Problems solved by technology

[0003] The water meter is connected in series on the water pipe, and in order to observe the verticality of the water meter, the water meter and the connecting pipes at both ends must be exposed outside, and every winter, the temperature drops, when the temperature drops below zero, the exposed connecting pipe and the inside of the water meter The water in the water will freeze into ice, which will cause the pipe wall to burst, damage the water meter, and affect the normal water use of the door. The faucet at home is turned on and kept in a trickle state. When encountering low temperature, the effect is not ideal, and it will also cause waste of water resources and waste of money.

Embodiment

[0023] refer to Figure 1-5 , a water meter antifreeze device, including a water meter box 1, a plurality of water meters 2 are installed in the water meter box 1, each water meter 2 is connected to a connecting pipe 3 at both ends, and a first protective frame is fixedly connected to the inner wall of the water meter box 1 rear side 4. The upper end of each connecting pipe 3 and the part in the water meter box 1 are connected with a connecting block 6. The upper end of the connecting block 6 is sealed and rotated through and provided with a rotating shaft 7. The lower end of the rotating shaft 7 extends to the inside of the connecting pipe 3 and fixes the sleeve Connected with the first bevel gear 8, on the inner wall of the connecting pipe 3 and at the left and right positions of the connecting block 6, there is a rotating cylinder 9 rotatably connected. The opposite sides of the two rotating cylinders 9 in the tube 3 are fixedly connected with annular bevel gears 11, and ea...

Abstract

The invention discloses a water meter anti-freezing device which comprises a water meter box, a plurality of water meters are installed in the water meter box, the two ends of each water meter communicate with connecting pipes, a first protection frame is fixedly connected to the inner wall of the rear side of each water meter, and the part, located in the water meter box, of the upper end of each connecting pipe communicates with a communicating block, a rotating shaft is rotationally arranged at the upper end of the communicating block in a sealed and penetrating mode, the lower end of the rotating shaft extends to the position close to the interior of the connecting pipe and is fixedly connected with a first bevel gear in a sleeving mode, rotating cylinders are rotationally connected to the positions, on the left and right positions of the communicating block, of the inner wall of the connecting pipe, and four spoilers are evenly and fixedly connected to the inner walls of the rotating cylinders in the circumferential direction, annular bevel gears are fixedly connected to the opposite sides of the two rotating cylinders located in the same connecting pipe. The anti-freezing device has the advantages that when the temperature is lower than zero DEG C, water in the connecting pipe can be kept in a moving state, the anti-freezing effect is achieved, and compared with an existing anti-freezing method, the anti-freezing device is more practical and effective.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to a water meter antifreeze device. Background technique [0002] A water meter is an instrument for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. Water meters are instruments that record the water consumption of tap water. They are installed on water pipes. The rotation of the pointer or character wheel on the watch indicates the amount of water passing through. [0003] The water meter is connected in series on the water pipe, and in order to observe the verticality of the water meter, the water meter and the connecting pipes at both ends must be exposed outside, and every winter, the temperature drops, when the temperature drops below zero, the exposed connecting pipe and the inside of the water meter The water in the water will freeze into ice, which will c...
