They bear the heavy responsibility of accurately measuring water consumption and are the basis for achieving reasonable allocation and efficient management of water resources. Generally, water meters are equipped with impellers inside, which are connected to the water metering mechanism. When water flows through the water meter, it drives the impeller to rotate, and the impeller changes the digital display on the water metering mechanism, thereby measuring the amount of water used. However, there are the following defects: In low temperature environments, existing water meters face severe challenges.

[0020] The rotating metering assembly 5 includes a turntable 501 installed inside the housing 1. A rotating shaft 502 is coaxially installed on the turntable 501. The rotating shaft 502 is connected to the meter body 2. The rotation of the rotating shaft 502 drives the counting mechanism inside the meter body 2 to meter the water volume. A fan blade 503 is equiangularly installed on the outer side of the rotating shaft 502, and a convex ice-breaking member 504 is arranged inside the fan blade 503.

A plurality of rows and columns of side grooves 5043 are symmetrically formed on both sides of the movable groove 5042. A piston block 5044 is movably installed inside the side groove 5043. Ice-breaking cones 5045 are uniformly arranged at the end of the piston block 5044 away from the inside of the movable groove 5042. A moving driving member is arranged inside the movable groove 5042. The moving driving member synchronously drives the piston blocks 5044 on the corresponding fan blades 503 to move. An internal cavity 5041 is formed inside the turntable 501.

A piston block 5044 is movably installed inside the side groove 5043. Ice-breaking cones 5045 are uniformly arranged at the end of the piston block 5044. During anti-freezing, after pushing the first friction plate 50410 to move, each piston block 5044 is pushed to move so that the ice-breaking cones 5045 move to the outside of the fan blade 503. When the rotating shaft 502 rotates, the ice-breaking cones 5045 can break the ice debris in the water inside the housing 1, avoiding freezing caused by excessive ice debris.

[0022] The heating and anti-freezing component 505 includes a fixed shaft 5051 coaxially and fixedly installed inside the internal cavity 5041. Second friction plates 5052 are arranged at equal angles on the outer side of the fixed shaft 5051. The number of the second friction plates 5052 is the same as the number of the fan blades 503. Guide cylinders 5053 are installed at equal angles on the outer side of the fixed shaft 5051. Guide rods 5054 are movably installed inside the guide cylinders 5053. One end of each guide rod 5054 is fixedly connected to the corresponding second friction plate 5052. A moving groove 5056 is formed inside the fixed shaft 5051. Second sliding grooves 5057 are formed at equal angles on the outer side of the moving groove 5056. The second sliding grooves 5057 correspond to the guide cylinders 5053 one by one. A sliding block 5058 is slidably installed inside the moving groove 5056. A first sliding groove 5055 is formed on one side of each guide cylinder 5053 close to the sliding block 5058. Second connecting rods 5059 are hingedly installed at equal angles on the outer side of the sliding block 5058. The other ends of the respective second connecting rods 5059 are hinged to the respective guide rods 5054. A fixed cylinder 50512 is fixedly installed on one side of the housing 1 away from the watch body 2. An internal plate 50513 is movably installed inside the fixed cylinder 50512. A push rod 50510 is fixedly installed on the internal plate 50513. The push rod 50510 penetrates into the moving groove 5056 and is fixedly connected to the sliding block 5058. A second spring 50514 is fixedly installed on one side of the internal plate 50513 close to the housing 1. One end of the second spring 50514 is fixedly connected to the inner wall of the end of the fixed cylinder 50512. A magnet 50515 is installed on the internal plate 50513. An electromagnet 50516 is installed at the end of the fixed cylinder 50512. A rotating groove 50511 is formed at one end of the turntable 501 close to the fixed cylinder 50512. The outer wall of the fixed shaft 5051 is in close contact with the inner wall of the rotating groove 50511. When the electromagnet 50516 is energized, it drives each second friction plate 5052 to move outwards. On the one hand, it pushes the first friction plate 50410 to move, so that the ice-breaking cone 5045 moves out of the outer side of the fan blade 503 to break the ice. On the other hand, the rotation of the rotating shaft 502 causes friction heat generation between the first friction plate 50410 and the second friction plate 5052, and the heat is transferred to the turntable 501, thereby heating the inside of the housing 1 to achieve an anti-freezing effect.

[0023] The heating enhancement component 506 includes plate grooves 5061 equiangularly formed on the outer wall of the turntable 501. The plate grooves 5061 are arranged staggeredly with the fan blades 503. A heat conduction plate 5062 is movably installed inside the plate grooves 5061. An inner baffle 5063 is installed at one end of the heat conduction plate 5062 located inside the inner cavity 5041, and an outer baffle 5064 is installed at the other end of the heat conduction plate 5062. Two third connecting rods 5065 are symmetrically and hingedly installed on the side of the inner baffle 5063 away from the heat conduction plate 5062. The other ends of the two third connecting rods 5065 are respectively hinged to two adjacent first friction plates 50410. Two heat conduction blocks 5066 are symmetrically installed on the side of the first friction plate 50410 close to the fan blade 503. Among them, the materials of the turntable 501, the heat conduction blocks 5066, the heat conduction plate 5062, the inner baffle 5063, and the outer baffle 5064 are all made of heat-conducting metal materials. During the outward movement of the first friction plate 50410, the heat conduction plate 5062 between two adjacent first friction plates 50410 is driven to move outward through the third connecting rod 5065, and the heat conduction plate 5062 is in close contact with the turntable 501, so as to increase the contact area with the water in the housing 1, thereby improving the heating effect on the water and enhancing the anti-freezing effect.

[0024] Working principle: During 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 the water enters the housing 1 from the water inlet pipe 3, the water pressure acts on the fan blade 503, pushing 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. When the device is used in winter, ice slag is likely to appear inside the housing 1 at low temperatures, which will affect the rotation of the rotating shaft 502, and then cause the water flow rate inside the housing 1 to slow down easily, resulting in freezing inside the housing 1. At this time, the user energizes the electromagnet 50516. After the electromagnet 50516 is energized, it generates a repulsive force on the magnetic block 50515, pushing the push rod 50510 and the sliding block 5058 to move towards the side of the guide cylinder 5053. Through a plurality of second connecting rods 5059, each second friction plate 5052 is pushed to move away from the fixed shaft 5051. During the outward movement of the second friction plate 5052, each first friction plate 50410 is pushed to move towards the side of the fan blade 503 until the end face of the heat conduction 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 through the first connecting rod 5048, the piston block 5044 is pushed to move outward along the side groove 5043, so that the ice-breaking cone 5045 moves to the outside of the fan blade 503. During the rotation of the rotating shaft 502, the ice-breaking cone 5045 on the fan blade 503 can break the ice slag in the housing 1 to ensure the water flow rate and play an anti-freezing role. Among them, when the second friction plate 5052 moves outward, its convex outer wall is closely attached to 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, so as to ensure that when the second friction plate 5052 moves outward, each first friction plate 50410 is pushed to move outward synchronously, and during the rotation of the rotating shaft 502, the contact between the first friction plate 50410 and the second friction plate 5052 is ensured, and the back movement of the first friction plate 50410 is avoided; During the water flow, the rotating shaft 502 is driven to rotate, causing a relative displacement between the first friction plate 50410 and the second friction plate 5052. During the continuous rotation of the rotating shaft 502, the first friction plate 50410 and the second friction plate 5052 continuously rub against each other, generating heat through friction, and the heat generated is transferred to the turntable 501 through the heat conduction block 5066 to heat the inside of the housing 1, thereby improving the anti-freezing effect of the housing 1; When the first friction plate 50410 moves towards the side of the fan blade 503, the heat conduction plate 5062 between two adjacent fan blades 503 is pushed to move outward through the third connecting rod 5065. The heat conduction plate 5062 is closely attached to the turntable 501, thereby increasing the contact area between the turntable 501 and the water in the housing 1, improving the heating effect on the housing 1 and the anti-freezing effect. In the original state, the external baffle 5064 is closely attached to the outer wall of the turntable 501 to prevent water from entering the internal cavity 5041. After moving, the internal baffle 5063 is closely attached to 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.
