Problems solved by technology

[0002] The water valve driving device of a conventional smart water meter touches the switch, the motor stops rotating, and the gears do not stop due to inertia, which may easily cause the gears to be stuck. Turn the magnet holder to the middle position, and a pair of magnets will generate a force opposite to the direction of rotation. It is easy to stop, and the drive worm will also be stuck

Embodiment Construction

[0010] Please refer to the figure, a water meter water valve driving device for intelligent meter reading. The front of the frame 12 is fixed with a rotating magnet frame 2 through a rotating shaft 11, and there are two antennae 2-1 at both ends. The rotating magnet frame is equipped with a pair of The magnets 3a and 3b are equipped with two switches 1 that can be touched by the antennae 2-1 of the magnet frame in the middle of the rotation path of the rotating magnet frame. The reverse side of the frame is cast with two shaft seats 12-1 for installing the transmission worm 7, the thin shafts at both ends of the worm are sleeved in the shaft seat, and the two ends of the transmission worm mesh with the driving gear 6 and the driven gear 8 respectively. There is a moving magnet 4 in the center, a movable magnet positioning frame 9 above the rotating magnet frame 2, a movable magnet 5 inside, and a water valve 10 above the positioning frame.

Abstract

A water valve driving device used for realizing intelligent meter copying and set on water meter is fixing rotary magnetic iron frame at front surface of frame, setting a pair of magnetic iron in said magnetic iron frame, arranging two contacts enabling to contact with two switches at two sides of horizontal axle in said magnetic iron frame, engaging two ends of driving worm separately with driving gear and driven gear, setting magnetic positioning frame on rotary magnetic iron frame and setting water valve on said positioning frame.

Description

technical field [0001] The invention relates to a water meter water valve driving device for intelligent meter reading. Background technique [0002] When the touch rod of the water valve drive device of the conventional smart water meter touches the switch, the motor stops rotating, and the gear is easy to get stuck due to the inertia of the gear. When the magnet frame is rotated to the middle position, a pair of magnets generate a force opposite to the rotation direction. It is easy to stop, and the transmission worm will also be stuck. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above defects and provide a water meter water valve driving device for intelligent meter reading. [0004] The technical solution of the present invention is to provide a water meter water valve driving device for intelligent meter reading. The rotating magnet frame is in the shape of a waist with only two tentacles. The two switches are arranged si...
