Description

Technical Field

[0001] The utility model relates to the technical field of water meter equipment, in particular to a water meter with antifreeze effect. Background Art

[0002] A water meter is an instrument for measuring water flow and is an essential part of a tap water system. The water meter includes a water meter body, a dial, and an interface. The water meter body is connected to the water supply pipeline through the interface, and the dial is installed on the water meter body to display the water flow. The water meter body includes various detection devices.

[0003] Chinese patent CN218847306U discloses an antifreeze tap water meter. In this utility model, when using water, the telescopic rod is shortened to drive the spring piece to slide a certain distance toward the outside of the water inlet end to avoid blocking the water flow. When not using water, the telescopic rod is extended to drive the spring piece to reset. Under the driving action of the driving mechanism, the spring piece is constantly vibrated to suppress the freezing of the water body, which has an antifreeze effect and ensures the normal operation of the water meter at low temperatures. However, this water meter does not take insulation and antifreeze measures for the water meter body. When encountering cold weather, the water inside the water meter will freeze and expand, causing the water meter to rupture or be damaged, affecting the normal water supply and causing economic losses to users. In addition, the instruments in the water meter are very likely to fail in cold weather, causing the water meter to be unable to work normally. Utility Model Content

DETAILED DESCRIPTION

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0027] like Figure 1-Figure 6As shown, the water meter with antifreeze effect in this embodiment includes a water meter body 105, which is connected to a water inlet pipe 102 and a water outlet pipe 103, and an insulating shell 104 is arranged outside the water meter body 105, and an upper shell cover 100 is clamped on the insulating shell 104, and an observation window 101 is arranged on the upper shell cover 100, and a heating mechanism is arranged inside the insulating shell 104, a defogger mechanism 300 is arranged at the position of the observation window 101 on the upper shell cover 100, and a locking mechanism 200 is arranged on the insulating shell 104 for facilitating the quick installation of the upper shell cover 100.

[0028] When the weather is cold, the locking mechanism 200 is used to install the upper shell cover 100 and the insulation shell 104 on the water meter body 105 to cover the entire water meter body 105. The upper shell cover 100 and the insulation shell 104 are both provided with insulation layers, which can effectively isolate the external cold air. The water inlet pipe 102, the water outlet pipe 103 and the water meter body 105 are heated by the heating mechanism to prevent the water from freezing. When the internal temperature of the upper shell cover 100 is higher than the external temperature, it is easy to cause fog on the observation window 101. When it is necessary to check the water meter body 105, the defogger mechanism 300 can be used to wipe the observation window 101 to remove the fog.

[0029] By setting the upper shell cover 100 and the heat-insulating shell 104, the external low temperature is effectively isolated and the heat loss inside the water meter body 105 is reduced. By setting the heating mechanism, the water inlet pipe 102, the water outlet pipe 103 and the water meter body 105 can be heated to prevent the water from freezing, ensuring that the water meter body 105 can still work normally in extremely cold weather. By setting the defogger mechanism 300, the fog on the observation window 101 can be easily removed, which is beneficial for the staff to check the water meter body 105, thereby improving the practicality and flexibility of the water meter.

[0030] like Figure 2-Figure 3 As shown, the heating mechanism includes a heating wire 108, and the heating wire 108 is arranged on the inner bottom wall of the insulation shell 104. A frame 107 is provided on the insulation shell 104 above the heating wire 108, and the water meter body 105 is placed on the frame 107. The heating wire 108 is powered by a battery. The water inlet pipe 102, the water outlet pipe 103 and the water meter body 105 are heated by the heating wire 108 to prevent water from freezing, thereby ensuring that the water meter body 105 can still work normally in extremely cold weather.

[0031] like Figure 1-Figure 4As shown, the defogger mechanism 300 includes a wiping rod 304, a guide groove 301 is provided at the position of the observation window 101 on the upper shell cover 100, one end of the wiping rod 304 is slidably fitted in the guide groove 301, a through hole is provided at a position on the upper shell cover 100 away from the guide groove 301, the other end of the wiping rod 304 extends to the outside of the upper shell cover 100 through the through hole, the wiping rod 304 is rotatably arranged in the through hole, a bellows 303 in contact with the wiping rod 304 is provided in the through hole, a handle 302 is provided on the end of the wiping rod 304 extending outside the upper shell cover 100, when it is necessary to check the water meter body 105, the wiping rod 304 is moved by the handle 302, so that the wiping rod 304 rotates along the guide groove 301, the observation window 101 is wiped by the wiping rod 304, and the mist on the observation window 101 is wiped off, so that the water meter body 105 can be better viewed, thereby improving the practicality of the water meter.

[0032] like Figure 2-Figure 6 As shown, the locking mechanism 200 includes a first latching tooth 204 and a second latching tooth 212. The heat-insulating shell 104 is symmetrically provided with an ear plate 201 along the central axis of the heat-insulating shell 104. A gear 202 is rotatably provided on the ear plate 201. The gear 202 is further provided with a moving column 203. The first latching tooth 204 is provided on the moving column 203 and is distributed along the circumference of the moving column 203. The upper shell cover 100 is provided with a side plate 210 corresponding to the guide groove 301. The side plate 210 is provided with a gear 202 rotating on the ear plate 201. The gear 202 is further provided with a moving column 203. The first latching tooth 204 is provided on the moving column 203 and is distributed along the circumference of the moving column 203. 203 is matched with a clamping block 211, and a second clamping tooth 212 is arranged on the clamping block 211. The second clamping tooth 212 is meshed and connected with the first clamping tooth 204. When the upper shell cover 100 is installed, the clamping block 211 is clamped into the movable column 203, and the gear 202 is rotated to drive the movable column 203 to rotate, so that the first clamping tooth 204 is meshed and connected with the second clamping tooth 212, thereby fixing the upper shell cover 100, realizing the rapid installation of the upper shell cover 100, and improving the convenience of water meter installation.

[0033] The ear plate 201 is provided with a mounting block 205, which is a hollow structure with an opening on one side. The opening of the mounting block 205 is close to the gear 202. A limiting block 207 is slidably matched inside the mounting block 205. A spring 206 is provided between the end of the limiting block 207 and the inner wall of the mounting block 205. The limiting block 207 is meshed and connected with the gear 202. When the gear 202 is not turned, the limiting block 207 is popped out of the mounting block 205 by the spring 206 and meshed with the gear 202 to fix the position of the gear 202 to prevent the gear 202 from rotating due to accidental touch, causing the upper shell cover 100 to loosen or fall off, thereby improving the reliability of the water meter.

[0034] like Figure 5As shown, the inner wall of the mounting block 205 is symmetrically provided with slide grooves 208 along the central axis of the mounting block 205, and sliders 209 are slidably fitted in the slide grooves 208. The ends of the two sliders 209 are fixedly connected to the side walls of the limit block 207. When the limit block 207 moves, the slider 209 is driven to slide in the slide groove 208, which guides and limits the movement of the limit block 207, makes the limit block 207 move more smoothly, enhances the fixing effect of the limit block 207 on the gear 202, and improves the stability of the water meter.

[0035] like Figure 3-Figure 4 As shown, positioning grooves 106 are provided at the four corners of the top of the thermal insulation shell 104, and positioning columns 110 corresponding to the positioning grooves 106 are provided at the bottom of the upper shell cover 100. When it is necessary to install the upper shell cover 100 on the thermal insulation shell 104, the positioning columns 110 are respectively inserted into the corresponding positioning grooves 106 to limit the position of the upper shell cover 100 and play a positioning role, making the installation of the upper shell cover 100 more convenient, reducing deviations, and improving the practicability of the upper shell cover 100 during installation.

[0036] A sealing gasket 109 is provided on the upper shell cover 100 and the thermal insulation shell 104 at the position of the water inlet pipe 102 and the water outlet pipe 103. The sealing gasket 109 is provided to enhance the sealing performance between the upper shell cover 100 and the thermal insulation shell 104, avoid the loss of heat inside the upper shell cover 100, improve the thermal insulation effect of the water meter body 105, and achieve a better anti-freeze effect.

[0037] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
