Abstract

The utility model relates to an adjusting water meter, belonging to the water meter class. The utility model is composed of a shell, an impeller variable speed device and a pointer, and a gear rod at the end of the variable speed device is driven with a helical gear which is engaged with a sliding screw rod; the front end of the screw rod has a stopper, the back end has a step pin, and the back end of the screw rod has an adjusting sleeve; the front part of the adjusting sleeve has a pin gap, and the back end face has a magnet block; the back side on the water meter shell is fixed with a box body, a micromotor and a decelerator are installed in the box body, an outer suction disc is fixed on an output shaft of the decelerator, a magnet block is installed on the suction disc, and a power socket is also arranged on the box body. The distance of the stopper away from a water outlet is adjusted by the rotation of the motor, the distance is corresponding to the paid water fee of a water user, when the water fee is not paid in time, the stopper stops the water path, and water can not be used.

Description

Adjustable water meter

The utility model belongs to what water meter class.

Existing water meter has two kinds of dry type and wet types, and its structure is basic identical, by what be made up of the gear set variator of the impeller in the glass of the housing of intake-outlet and housing upper port and gland, the housing, impeller-driven and pointer.Though this water meter is the water measurement amount accurately, can not restrict water supply, the water user who has does not hand over the water rate water that does as usual, and just can not limit water user's water of not handing over water rate.

The purpose of this utility model is: provide a kind of and pay the adjustable water meter how many water rates comes quantitative water supply according to the water user.

The technical solution of the utility model is: based on by by impeller, the gear set variator of impeller-driven and the water meter that pointer is formed in the glass of the housing of intake-outlet and housing upper port and gland and dividing plate, the housing; The not end rack of gear set variator drives a spiral gear; Spiral gear is engaged with a sliding screw, and screw front end is equipped with shutoff, spiro rod rear end has the shelves pin, and spiro rod rear end is fitted with regulating sleeve; The front portion of regulating sleeve has two axial pin gap, rear end faces that magnet piece is housed; Rear side is fixed with a box body on water meter case, and micromotor and speed reduction unit are housed in the box body, is fixed with outer sucker on the output shaft of speed reduction unit, and magnet piece is housed on the sucker; On box body, also has supply socket.

Water meter of the present utility model has the management of the use of water of raising and water-saving good effect.

Accompanying drawing is a structural representation of the present utility model.

Drawing explanation and embodiment are described below: 1 is the housing that intake-outlet is arranged among the figure, and the upper port of housing has O-ring seal 3 and glass 4 and gland 2.The gear set variator 20 and the pointer 7 of impeller 19, impeller 19 drivings are housed in housing.The utility model is on the basis of above-mentioned existing water meter, do not hold rack to drive at the gear set variator spiral gear 23 is arranged, spiral gear 23 is engaged with a sliding screw 8, sliding screw 8 front ends are equipped with the shutoff 24 of corresponding water delivering orifice, can be fixed with the bidding quotation 22 of visual usefulness in the shutoff back, the position of bidding quotation 22 is to show the position of shutoff 24.There is shelves pin 21 rear end of sliding screw 8, and sliding screw 8 rear ends are fitted with regulating sleeve 10,9th, the support of regulating sleeve 10, the 6th, the support of screw rod 8; Regulating sleeve 10 front portions have two axial pin gap, rear end faces that magnet piece 16 is housed.Rear side is fixed with a box body 18 on water meter case 1, and micromotor 15 and speed reduction unit 13 are housed in the box body, is fixed with outer sucker 12 on the output shaft of speed reduction unit, on the sucker 12 magnet piece is housed.Supply socket 14 also is housed on box 18.After motor 15 energising, outer sucker 12 rotates, and regulating sleeve 10 rotates under the suction of magnet piece, rotates simultaneously at the effect lower slider screw rod 8 of shelves pin 21, and moves axially, and the number according to the water user pays dues is adjusted to corresponding position with screw rod 8.Water flowing afterwards, impeller 19 rotates, and spiral gear 23 rotates simultaneously, and at this moment 8 works of screw rod axially do not rotate to front slide, and until making shutoff 24 move to the mouth of a river, the water user then can't water as or else paying water rate.After the water user handed over money, the water resource management personnel come to insert socket 4 with special-purpose computer meter record instrument again rotated motor 15, opens the water route with moving after screw rod 8 and the shutoff 24.11 is that the top of location is protruding among the figure, and 17 is tachometer generators among the figure, sends the revolution pulse with what to computer meter record instrument and determines water adjusting quantity.Do not adopt the mode of computer meter record instrument, can not add sensor 17.5 is every the window of dish among the figure, makes bidding quotation 22 expose the purpose that reaches visual.
