Technical Field

[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. Water meters are divided into volumetric water meters and velocity water meters. The internal structure of a water meter can be divided into three parts from the outside to the inside: a shell, a sleeve, and an inner core. When the water meter is in use, it is necessary to use the water meter shell to install the water meter. When selecting the specifications of the water meter, you should first estimate the size and flow range of the flow rate usually used, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice. However, when the existing water meters are in use, the external ambient temperature is too low, causing the water in the pipe to freeze, which in turn causes freezing damage to the inside of the water meter. In severe cases, the water meter may freeze and crack, affecting the subsequent use of the water meter. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-6 The utility model provides a technical solution: a water meter case to prevent freezing and cracking, including a shell 10, a connecting pipe 1 20, a connecting pipe 201, a cavity 30, a blocking block 301, elastic silicone 302, a shell 40, a heating box 50, a heat conducting rod 1 501, a heating wire 502, a heat conducting rod 2 503, a pipeline 504, and a chamber 505;

[0034] The water meter case can prevent the outer shell 10 from freezing and cracking. The specific implementation is as follows:

[0035] The housing 10 is configured as a hollow cylindrical structure, and a connection tube 1 20 is fixedly connected to the surface of one end of the housing 10; a connection tube 201 is fixedly connected to the surface of the housing 10, and a storage mechanism is provided inside the housing 10, and the storage mechanism includes: a cavity 30 is embedded in the surface of the housing 10, and a block 301 is embedded in the bottom of the cavity 30, and an elastic silicone 302 is fixedly connected to the surface of the block 301, and the other end of the elastic silicone 302 is fixedly connected to the watch case 40, The watch case 40 is installed on the surface of the cavity 30, the connecting tube 201 and the connecting tube 1 20 are symmetrically arranged on both sides of the outer shell 10, and the outer shell 10 is respectively connected with the connecting tube 201 and the connecting tube 1 20, the blocking block 301 is slidably connected with the cavity 30, a gasket is arranged between the cavities 30, and the cavity 30 and the outer shell 10 are connected through, the elastic silicone 302 is arranged as a shrinkage structure, and the elastic silicone 302 is arranged between the blocking block 301 and the watch case 40.

[0036] The block 301 blocks the cavity 30, and a gasket is provided on the surface of the block 301 to seal the cavity 30 to prevent water from entering the cavity 30. When the water pressure inside the shell 10 increases, the air pressure drives the block 301 to move upward inside the cavity 30, causing the elastic silicone 302 to shrink. At the same time, the pressure inside the shell 10 is relatively small, and the elastic force received by the elastic silicone 302 is reduced. The elastic silicone 302 restores and drives the block 301 to move downward, so that the position of the block 301 is restored. An ultrasonic transducer is provided inside the case 40, and the ultrasonic transducer can use ultrasonic waves to The water flow is detected. When the water is stopped, the water remains inside the shell 10 and accumulates inside the shell 10. When the temperature drops, the water condenses on the inner bottom surface of the shell 10. When the water freezes, its volume increases, causing the water to condense upward from the bottom of the shell 10. When the ice condenses, the end of the ice fits with the bottom of the block 301. At this time, the ice pushes the block 301 upward, causing the block 301 to move upward inside the cavity 30. At this time, the block 301 pushes the elastic silicone 302 upward, causing the elastic silicone 302 to shrink. At this time, the ice condenses inside the cavity 30, which can increase the ease of the inside of the shell 10 and prevent the shell 10 from freezing and cracking.

[0037] The water meter case heats the interior of the housing 10 to melt the ice inside the housing. The specific implementation is as follows:

[0038] A heating mechanism is provided on the surface of the shell 10, and the heating mechanism includes: a heating box 50 is fixedly connected to the bottom of the shell 10, and a heat-conducting rod 1 501 is embedded in the interior of the heating box 50, a heating wire 502 is fixedly connected to the interior of the heating box 50, and the end of the heat-conducting rod 1 501 penetrates the heating box 50 and is inserted into the interior of the shell 10, and a heat-conducting rod 2 503 is fixedly connected to the end of the heat-conducting rod 1 501, and the heat-conducting rod 2 503 is arranged in the interior of the shell 10, and a pipe 504 is symmetrically fixedly connected to the surface of the heating box 50, a chamber 505 is installed on the surface of the connecting pipe 1 20 and the connecting pipe 2 201, and the chamber 505 is connected to the pipe 504, the heating box 50 and the pipe 504 are through-connected, and the pipe 504 and the chamber 505 are through-connected, the heat-conducting rod 2 503 is arranged on the inner bottom surface of the shell 10, and the end of the heat-conducting rod 1 501 is arranged corresponding to the position of the heating wire 502.

[0039] When the water inside the shell 10 condenses, ice condenses on the surface of the second heat-conducting rod 503, and the heating wire 502 is started. The heating wire 502 heats the inside of the heating box 50, and the heat-conducting rod 1 501 absorbs the heat inside the heating box 50. At the same time, the heat-conducting rod 1 501 transfers the heat to the second heat-conducting rod 503. At this time, the temperature of the second heat-conducting rod 503 becomes higher, which can heat the ice on the surface of the second heat-conducting rod 503 to melt the ice on the surface of the second heat-conducting rod 503, and transfer the heat to the inside of the shell 10 to heat the ice inside. At the same time, the heat inside the heating box 50 enters the inside of the chamber 505 through the pipe 504 to heat the chamber 505. At this time, the chamber 505 transfers the heat to the surfaces of the second connecting pipe 201 and the first connecting pipe 20, so that the temperatures of the surfaces of the second connecting pipe 201 and the first connecting pipe 20 increase, and the condensed ice inside the second connecting pipe 201 and the first connecting pipe 20 melts.

[0040] Working principle: When using the anti-freeze cracking water meter case, a cavity 30, a block 301 and elastic silicone 302 are set to prevent the outer shell 10 from freezing and cracking. A heat conducting rod 1 501, a heating wire 502 and a heat conducting rod 2 503 are set to heat the inside of the outer shell 10 to melt the ice inside, thereby increasing the overall practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
