WEISERV10.03Operating ConstructionXuzhou Weisi Water Affair Science & Technology Co.,Ltd.Jiangsu P.R.ChinaJD05 Tipping Bucket Rain Gauge Operating Construction1 OutlineThe instrument is precipitation measurement primary instrument which is consistent with related requirements of Chinese standard GB/T 11832-2002< Tipping Bucket Rain Gauge>, <Hydrological forecasting device-telemetering Rain Gauge>.The core part-tipping bucket adopts three-dimensional streamlined design，which turn over rain fluently, dust self-cleaning and wash easily.2 Structure and FeaturesAs shown in Fig. 1, the instrument consists of the rain receiver 1, filter 2, diversion funnel 3, tipping bucket bracket 4, tipping bucket 5, tipping bucket shaft sleeve 6, inclination adjusting device 7, horizontal adjusting device 8, permanent magnet steel 9, reed switch 10, output terminal 11, drain funnel 12, base 13, stainless steel housing 14, base support leg 15, diversion funnel filter 16, etc.Unlike other tipping gauges, the tipping bucket shaft sleeve is an integrated rotary positioning structure. The tipping bucket 5 is mounted on jewel bearing with 2 sleeves through the tipping shaft, which install conveniently, making the tipping bucket assembly and disassembly easier, and no need to adjust the distance between the two sleeves.3 Main technical parameters3.1 Rain Gauge Receiver: φ200mm; Edge angle: 40o～45°3.2 Resolution: 0.5mm3.3 Precipitation intensity : 0.01mm～4mm/min (Maximum permitted : 8mm/min)3.4 Accuracy level: ≤±3%(Indoor artificial precipitation: subject to water discharge of instrument ) 3.5 Signal: reed switch signal output（open, stop）3.6 Working condition: ambient temperature : 0℃～50℃relative humidity: <95%(40℃)3.7 Dimension：φ216×410 2Kg4 Installation and testing4.1 Checking the instrumenta. Make sure no parts are missing according to the packing list of operating instructionb. Read the product manual, and check the product certificate carefullyc. Check the appearance of the instrument ,especially the tipping bucket,and put it properly to prevent damaging the tipping bucket axis of the shaft and the end of the bucket at both ends of the arc-shaped water tip, and in any cases do not touch the bucket inner wall to avoid fouling it.4.2Installation and adjusting indoor4.2.1 Installing base support legAccording to fig.1, remove the housing, 3 stainless steel support legs should be installed in the circular base on the corresponding installation location with 2 M4 ×25 stainless steel countersunk head screws, flat washers, nuts, and tighten the screw nuts to prevent loosening, and then level overall of the instrument movement on the desktop.Fig. 1Fig. 2 Fig 34.2.2 Installing tipping bucketa Ensure drain funnel 12 with fig.2, and pull 12 up awany from the installing hole of base 13.b Ensure shaft sleeve 6 with fig.3, gently lift the handle on the right side of the sleeve 90°upwards，pull the right sleeve away from installing hole, the jewel bearing is shown in the sleeve.c The two magnets on the dome face the reed switch on the bracket 4, put the bucket into the centre of bracket 4 lightly, make the pivot aim to cnetre of the right installing hole, then put the right shaft sleeve into right installing hole till the right pivot of tipping bucket enter into bearing hole, turn the handle of the right sleeve down 90°to put the circular depression into location hole. The mounted tipping bucket should turn freely, the distance shoule be 0.3mm between bucket axis and 2 sleeves.4.2.3 Installing drain funnel 12Using 4.2.2 a opposite process to put the funnel 12 back,and impact downward.4.2.4 Adjusting the bracket level.Adjusting the N1/N2/N3, M1/M2/M3 screws till the bubble level in the centre.4.2.5 Checking the signalAdjust AVOmeter at 1K “Ω”, use test pencil (or Counter)to contact the output terminal behind instrument bracket, and stir the metering bucket lightly, then check the reed switch signal (“open, stop”is normal or not). The instrument has been adjusted to best optimum coupling position (the distance between reed switch and magnet is about 2±0.5mm). If output wrong, check reed switch is in good condition, or all connections touch well, or adjust position between reed switch and magnet, problem solved.4.3 Installation and adjusting outdoora. Manufacturing concrete baseManufacture the concrete base as Fig. 4, Measurement should be 40X40X17 cm (above the ground). The reciever’s height from ground is 70cm after installation; Punch3 φ12mm diameter installing holes in the concrete base, 10 cm depth, the installing holes locate equal 120° in φ240mm circle.b. Installing the base plate: put expansion bolts into installing holes respectively, and fasten the bolts with grommets and anchor nuts, then install stand plate of instrument base on the 3 expansion bolts.c. Adjusting movement level, tighten instrument base: change 3 heighten screws until bubble moves into the centre, then tighten the 3 stand legs and heighten screws of instrument with tighten screws.d Installing signal transmission lineLead the transmission line from machine room through protection tube to concrete base. Then pass trough wire hole in the base, connect with output signal terminal, lock the locking parts of cable tightly.图 45 Simulating precipitationThe instrument has been carried out artificial precipitation simulation precipitation test and has been based on factory inspection records to produced fig. 5 shows the relationship between rain intensity and accuracy curve for the user reference. Users in the completion of the indoor installation is generally no longer need to manually simulate the precipitation test, you can directly install the use of outdoor.If the accuracy is out of errorin during use, the instrument should be carried out artificial simulated precipitation test again , re-adjust the instrument, the method as follows:a Tools：1 dedicated rain measuring cylinder , a small dropper；b check before test：Taking down the housing to check the bubble level is in the centre, bucket is freely, the water is smooth or not, the reciever and diversion funnel should be wet adequately with clean water.c Water injection testUsing two-step dripping method as follows：Pour 10mm clean water into diversion funnel with rain measuring cylinder till the bucket almost turn over, then the rest water in the cylinder should be injected by dropper into tipping bucket drop bydrop till turn over,trial and error, record the tip times and water amount; If tip times is 20,the amount is 9.7-9.85mm, there is no need to adjust instrument. If ＞9.85mm, it means the inclination of tipping bucket is too large,curve left shift, improve the height of the adjustment screw;If＜9.7mm,it means too small, curve right shift,lower the hight of screw；Generally, a circle of screw means 3-4% of accuracy.Fig. 56 Maintenancea. Daily maintenanceThe use of the environment is very poor, so the inwall of rain reciever should always be wiped with a soft cloth to keep clean, if found leaves and other foreign matter, clean up to keep the water flow immediatly. When the instrument is not used for a long time, it should be covered with a cover on the reciever of the instrument.Long-term work of the instrument should be generally clean up once a month, 3 months must be cleaned once;b. Washing tipping bucketUse banister brush to clean dirt, foreign matter in the inside of every tipping buckets with soluble caustic soda. And wash the inside with clean water, strictly prohibit touch inside of bucket by fingers or oil dirty things, otherwise the instrument may be out of alignment.c.Checking tipping bucketHolding the tipping bucket to keep it in the horizontal position, check the tipping bucket can freely flip. If not, it indicats that the dirt may be exsited between pivot and bearing.In accordance with the instructions 4.2.2 disassembly tipping bucket to remove dirt and reinstall. Note: It is strictly forbidden to add grease or other solution to the jewel bearing when cleaning the bucket.7 Failure and ExclusionThe table lists normal failure of instrument, reason and elimination methodCaution: the failure above is not always caused by rain gauge, output transmission cable of instrument, collecting data device, telemetering terminal machine etc, also should be checked after checking instrument problem, and excluded one by one.8 Packing listTipping bucekt rain gauge …………………………………………………………....… 1 set Rain reciever overlay …………………………………………………………………… 1 pc Tipping bucket………………………………………………………………………… 1 pc Base fixed legs …………………………………………………..…………………… 3 pcs M5×25 screws …………………………………………………………………………… 3 pcs M8×120 a nchor bolts ……………………………………………..…....…………………3 pcs Operating Instruction ………...............…………………………………........……… 1 pc Certificate..…................…………………………………………….……………… 1 pc。
