[0002] In today's water supply system, water meters are key devices in the metering mechanism, and their accurate measurement and stable operation are crucial. Water meters are widely used in various places such as residential houses, commercial buildings, and industrial facilities. They bear the heavy responsibility of accurately measuring water consumption and are the basis for achieving rational allocation and efficient management of water resources. Generally, water meters are equipped with an impeller inside, which is connected to the water metering mechanism. When water flows through the water meter, it drives the impeller to rotate, and the impeller causes the digital display on the water metering mechanism to change, thereby measuring the water usage. However, there are the following defects:

A second spring 50514 is fixedly installed on the side of the inner plate 50513 close to the shell 1. One end of the second spring 50514 is fixedly connected to the inner wall of the end of the fixed cylinder 50512. A magnetic block 50515 is installed on the inner plate 50513, and an electromagnet 50516 is installed on the end of the fixed cylinder 50512. The turntable 501 is close to the housing 1. A rotation groove 50511 is provided at one end of the fixed cylinder 50512, and the outer wall of the fixed shaft 5051 is in close contact with the inner wall of the rotation groove 50511. The electromagnet 50516 is energized to drive each second friction plate 5052 to move outward. On the one hand, it pushes the first friction plate 50410 to move, so that the ice-breaking cone 5045 moves out of the outside of the fan blade 503 to break the ice. On the other hand, the rotation of the rotating shaft 502 causes friction between the first friction plate 50410 and the second friction plate 5052 to generate heat, and transfers the heat to the turntable 501, thereby heating the inside of the shell 1 and having an anti-freeze effect.

[0041] The heating efficiency enhancement component 506 includes a plate groove 5061 opened at an equal angle on the outer wall of the turntable 501, the plate groove 5061 and the fan blade 503 are staggered, and a heat conducting plate 5062 is movably installed inside the plate groove 5061.

The first friction plates Two heat-conducting blocks 5066 are symmetrically installed on one side of 50410 close to the fan blade 503, wherein the materials of the turntable 501, the heat-conducting block 5066, the heat-conducting plate 5062, the internal baffle 5063 and the external baffle 5064 are all made of heat-conducting metal materials. During the outward movement of the first friction plate 50410, the heat-conducting plate 5062 between the two adjacent first friction plates 50410 is driven to move outward through the third connecting rod 5065, and the heat-conducting plate 5062 is in close contact with the turntable 501, thereby increasing the contact area with the water in the shell 1, thereby improving the heating effect on the water and improving the anti-freezing effect.

[0042] Working Principle: When in operation, first connect the water inlet pipe 3 to one end of the water pipe and the water outlet pipe 4 to the other end of the water pipe. After water enters the housing 1 from the water inlet pipe 3, the water pressure acts on the fan blades 503, driving the rotating shaft 502 to rotate. Then, the water flows out from the water outlet pipe 4. The rotation of the rotating shaft 502 drives the counting mechanism in the meter body 2 to measure the amount of water flowing through the housing 1.

[0043] When the device is used in winter, ice chips are likely to form inside the housing 1 at low temperatures, which in turn affects the rotation of the shaft 502, and in turn causes the water flow rate inside the housing 1 to slow down, resulting in freezing inside the housing 1.

[0044] At this time, the user energizes the electromagnet 50516. After being energized, the electromagnet 50516 generates a repulsive force on the magnetic block 50515, pushing the push rod 50510 and the sliding block 5058 toward the side of the guide cylinder 5053, and pushing each second friction plate 5052 toward the side away from the fixed axis 5051 through multiple second connecting rods 5059. During the outward movement of the second friction plates 5052, the first friction plates 50410 are pushed toward the fan blade 503 until the end face of the heat conducting block 5066 contacts the inner wall of the internal cavity 5041. The movement of the first friction plate 50410 drives the movement of each push plate 5047, and pushes the piston block 5044 outward along the side groove 5043 through the first connecting rod 5048, so that the ice breaker 5045 moves to the fan blade On the outside of 503, during the rotation of the rotating shaft 502, the ice-breaking cone 5045 on the fan blade 503 can break the ice inside the shell 1, ensuring the flow rate of water and playing an anti-freezing role. The second friction plate 5052 moves outward, and its convex outer wall is in close contact with the concave outer wall of the first friction plate 50410. When the second friction plate 5052 is located between two adjacent first friction plates 50410, the second friction plate 5052 can contact the two first friction plates 50410, thereby ensuring the outward movement of the second friction plate 5052, pushing each first friction plate 50410 to move outward synchronously, and during the rotation of the rotating shaft 502, ensuring the contact between the first friction plate 50410 and the second friction plate 5052, and preventing the first friction plate 50410 from moving back;

[0045] During the water flow, the rotating shaft 502 is driven to rotate, causing the first friction plate 50410 and the second friction plate 5052 to move relative to each other. As the rotating shaft 502 rotates continuously, the first friction plate 50410 and the second friction plate 5052 continuously rub against each other, generating heat through friction. The heat generated is transferred to the rotating disk 501 through the heat conducting block 5066, thereby heating the interior of the housing 1, thereby improving the antifreeze effect of the housing 1.

[0046] When the first friction plate 50410 moves toward the side of the fan blade 503, the third connecting rod 5065 pushes the heat conducting plate 5062 between the two adjacent fan blades 503 to move outward, and the heat conducting plate 5062 is in close contact with the turntable 501, thereby increasing the contact area between the turntable 501 and the water in the shell 1, improving the heating effect on the shell 1, and improving the anti-freezing effect. In the original state, the external baffle 5064 is in close contact with the outer wall of the turntable 501 to prevent water from entering the internal cavity 5041. After moving, the internal baffle 5063 is in close contact with the inner wall of the internal cavity 5041 to prevent water from entering the internal cavity 5041. At the same time, the external baffle 5064 can further increase the contact area with water.
