[0012] Advantages of the present invention:
[0013] A high-precision water meter for preventing freezing and cracking according to the present invention is provided with a detection body, a detection cavity, a rolling body, a measurement through hole, a sliding plate, a square groove, etc. Water flow enters the measurement through hole, pushes the sliding plate to slide in the measurement through hole, and the measurement through hole slides to discharge the water on the other side outwards through the square groove on the other side. When the sliding plate moves to the limit position, the servo motor drives the rolling body to rotate a certain angle, controls the next group of measurement through holes to align with the opening of the square groove, and the counting table accumulates and displays the rotation amount of the rolling body, completing the accurate measurement of the water flow. Compared with the rotary water meter, this device has higher measurement accuracy. By setting the servo motor, the rotation speed of the rolling body can be controlled, thereby controlling the flow rate of the water flow passing through this device, and reducing or increasing the flow rate of the water flow at the outlet according to needs.
[0014] When the outside temperature is lower than a certain level and the water flow in the pipe is stationary, in order to protect this device, the outlets at both ends of the square groove are disconnected. The servo motor drives the rolling body to rotate rapidly in the detection cavity, and the water inside the measurement through-hole is thrown out in all directions under the action of centrifugal force. The water flow enters the rotating communication ring and the water collecting tank through the drainage cavity. Another part of the water enters the side wall groove through the filtering arc plate and finally converges into the water collecting tank and is discharged, draining the water inside the water meter to avoid damage to the water meter caused by the expansion of frozen water. Compared with traditional heating protection, this device saves a large amount of energy and has high reliability.
[0015] By setting the descaling head, movable body, support rollers, arc plate, etc., this device can utilize the power of water flow. The descaling head rotates and moves in the measurement through-hole, and the descaling head descales the inner cavity of the water meter measurement through-hole regularly to avoid excessive accumulation of water scale, which may cause the sliding plate to fail to slide smoothly in the measurement through-hole. By setting sensors to indirectly detect water scale and automatically clean it, the measurement accuracy of this device is guaranteed. Brief Description of the Drawings

A sliding plate 14 is slidably provided inside the measurement through-hole 13. Square grooves 28 are communicated with the front and rear sides of the detection cavity 11. The connection opening between the square grooves 28 and the detection cavity 11 can be aligned with the opening of the measurement through-hole 13. A drainage cavity 29 is communicated with the side of the measurement through-hole 13. A side wall groove 18 is provided on the wall body of the detection cavity 11. A filtering arc-shaped plate 19 is provided at the opening of the side wall groove 18. The drainage cavity 29 is communicated with one end of the rolling body 12. A water collecting groove 21 is provided on the wall body of the detection cavity 11. A rotating communication ring 20 is provided at the opening of the drainage cavity 29. The rotating communication ring 20 is communicated with the water collecting groove 21. The rotating communication ring 20 is rotatably connected with the water collecting groove 21. The water collecting groove 21 is communicated with the side wall groove 18 and the drainage cavity 29. A drain pipe 22 is communicated with the outside of the water collecting groove 21.

The counting meter 15 is installed on the upper side of the connecting body 46. Sensors 48 are installed on the end walls at both ends of the measurement through-hole 13.
[0024] Install this device at a designated pipeline. Water flow enters the square groove 28 on one side and further enters the measurement through-hole 13. The water flow pushes the sliding plate 14 to slide inside the measurement through-hole 13. The sliding of the measurement through-hole 13 discharges the water on the other side outwards through the square groove 28 on the other side. When the sliding plate 14 moves to the limit position and touches the sensor 48, the servo motor 17 drives the rolling body 12 to rotate by a certain angle, controlling the next group of measurement through-holes 13 to be aligned with the opening of the square groove 28. The rotation of the rolling body 12 drives the pointer inside the counting meter 15 to rotate through the connecting body 46. In this way, the transfer and measurement of the water flow are completed reciprocally. When the outside temperature is lower than a certain degree and the water flow in the pipe is stationary, in order to protect this device, the outlets at both ends of the square groove 28 are disconnected. The connecting body 46 disconnects the connection between the counting meter 15 and the rolling body 12.

[0027] Preferably, an adjusting telescopic rod 39 is hinged outside the active body 47. The shaft of the adjusting telescopic rod 39 is rotatably connected to the end of the sliding rod 38.
[0028] The telescopic movement of the adjusting telescopic rod 39 drives the sliding rod 38 to slide in the chute of the active body 47. The adjusting telescopic rod 39 provides power for the support roller 37 to disengage from or engage with the roller chute 36.

[0030] The telescopic movement of the telescopic rod 40 drives the two groups of arc-shaped plates 41 to engage with or disengage from the threads of the central rod 30. When the arc-shaped plates 41 are threadedly connected to the outside of the central rod 30, the support roller 37 disengages from the roller chute 36.

[0034] The spring 35 pushes the straight tooth bar 33 to move outward. The straight tooth bar 33 drives the roller 32 to abut against the side wall of the detection cavity 11. When the rolling element 12 rotates in the detection cavity 11, the roller 32 rolls. The resistance brought by rolling friction is smaller, and it can play a certain sealing role to prevent water from overflowing through the gap between the rolling element 12 and the detection cavity 11.
