The first synchronous belt 2 is arranged in the middle of the cavity, the area of the cavity above the first synchronous belt 2 is a dry area 107, and the area of the cavity below the first synchronous belt 2 is a liquid area 106.

As shown in fig. 6, the outlet pipe 102 is connected to the lower half of the cavity inside the housing 1, i.e. the liquid area 106, and the through connection port of the inlet pipe 101 and the housing 1 is not higher than the center of the housing 1.

Three end surfaces of the water guard 201 positioned below the first timing belt 2 are respectively contacted with the inner walls of both sides and the bottom surface of the housing 1. In order to prevent the water from being blown, the water guard 201 is inclined. As shown in fig. 11 and 12, the inner walls of the two sides of the cavity inside the housing 1 are each concavely provided with an annular sliding groove 103, the end surfaces of the two sides of the end of the water baffle 201 are each convexly provided with a sliding rod 202, the height of the sliding groove 103 is the same as the outer diameter of the sliding rod 202, and the sliding rod 202 is slidably disposed inside the sliding groove 103.

The heating device 13 can dry the surface of the water baffle 201 moved to the inside of the drying area 107, and the dried mucous membrane is easy to fall off when being impacted by water once, thereby achieving the purpose of cleaning the water baffle 201. Meanwhile, in order to increase the sterilization effect, an ultraviolet lamp may be embedded in the inner wall of the drying region 107.

The heating device 13 and the ultraviolet lamp can be connected with an external power supply, and can also generate electricity by the water meter, and then the heating device 13 and the ultraviolet lamp are driven to work. The outer part of the shell 1 is fixedly provided with a generator 11 and an electric control box 12, the roller 3 or the sleeve 4 drives an input shaft of the generator 11 to rotate, and the generator 11 is electrically connected with the electric control box 12.

The output shaft 5 is sleeved with a driven gear 501. The sleeve 4 is internally provided with an intermediate gear 6, and two ends of a central shaft of the intermediate gear 6 are respectively inserted into the end faces of the two support columns 104.

The intermediate gear 6 is meshed with the ring gear 401 and the driven gear 501, respectively, that is, the ring gear 401, the intermediate gear 6, and the driven gear 501 are sequentially meshed. The number of teeth of the ring gear 401 is greater than that of the intermediate gear 6, and the number of teeth of the intermediate gear 6 is greater than that of the driven gear 501.

The top surface of the shell 1 is upwards concavely provided with a rotating groove 105, a striking device is arranged in the rotating groove 105, and the striking device comprises a rotating shaft 7 arranged in the rotating groove 105.

A plurality of rubber ropes 701 are fixed on the circumferential surface of the rotating shaft 7, and striking balls 702 are fixed at the tail ends of the rubber ropes 701. The distance from the hitting ball 702 to the axis of the rotating shaft 7 is smaller than the distance from the axis of the rotating shaft 7 to the top surface of the rotary groove 105, so that when the rotating shaft 7 rotates and the hitting ball 702 moves upwards, the rotary groove 105 does not interfere with the hitting ball.

For safety, as shown in fig. 3 and 4, the first pulley 502, the second pulley 703 and the second timing belt 8 are covered with a protective cover 9.

The working method of the water meter comprises the following steps:

A. water flow enters from the water inlet pipe 101 and then flows into the liquid area 106 below the first synchronous belt 2, the water baffle 201 is pushed to move towards the direction of the water outlet pipe 102, the first synchronous belt 2 drives the roller 3 to rotate, the central shaft of the roller 3 is fixedly connected with the input shaft of the gauge head 10, and therefore the roller 3 rotates to drive the gauge head 10 to count and measure water consumption.

B. The water flow always flows in the liquid flow field 106 below the first timing belt 2 and does not flow into the drying region 107 above the first timing belt 2, and the heating device 13 heats the water guard 201 inside the drying region 107 to dry the mucous membrane formed on the surface thereof. When water is used, the water flow pushes the first synchronous belt 2 to rotate again, the dried water baffle 201 rotates to the position of the water inlet pipe 101, and the water flow blows off the dry mucous membrane above the water baffle 201, so that the surface of the water baffle 201 is clean;

C. the output shaft 5 drives the input shaft of the generator 11 to rotate, so that electricity is generated, the electricity is stored in the storage battery after being rectified by the charging module in the electric control box 12, and the storage battery supplies power for the heating device 13.

Since the number of teeth of the ring gear 401 is larger than that of the intermediate gear 6, the number of teeth of the intermediate gear 6 is larger than that of the driven gear 501. The rotational speed of the output shaft 5 is therefore greater than the rotational speed of the roller 3, facilitating power generation.

D. The output shaft 5 drives the rotating shaft 7 to rotate through the second synchronous belt 8, the rotating shaft 7 drives the rubber rope 701 and the striking ball 702 to rotate, and in the moving process of the first synchronous belt 2, the rotating striking ball 702 strikes the water baffle 201 to vibrate the dry mucous membrane on the water baffle 201.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
