Description

Technical Field

[0001] This invention relates to the field of water meter antifreeze technology, specifically a water meter antifreeze and heat preservation device for high-altitude and cold regions. Background Technology

[0002] In cold, high-altitude regions, winters are frigid, with temperatures often dropping below freezing and extreme low temperatures being common. In such environments, water meters, as crucial devices for measuring water consumption, are widely used in residential homes, commercial spaces, and public facilities. Because water meters are typically installed outdoors or in cold stairwells, their normal operation faces significant challenges. Low temperatures can easily cause the water inside the meter to freeze, leading to problems such as meter damage, inaccurate readings, or even complete malfunction, affecting residents' normal water use and the management of water supply departments. To address the issue of freezing water meters in high-altitude and cold regions, some insulation measures have been adopted. For example, in some areas, simple insulation materials such as rock wool and foam are wrapped around the outside of the water meters. In addition, some places are trying electric heat tracing, which uses electric heating tape wrapped around the water meter and water pipes to generate heat and prevent freezing. Traditional water meter antifreeze and insulation installation methods often lack optimized designs specifically for cold regions. The installation steps are relatively complex and require a significant investment of manpower and time. For example, some outdated installation methods require complex connections and adjustments between the water meter and pipes. There is no convenient installation structure, making it difficult for installers to operate in cold environments and making it difficult to guarantee the accuracy and stability of the installation, thus increasing installation costs and the probability of errors. Summary of the Invention

This solves the problem that traditional water meter antifreeze and insulation installation methods often lack optimized designs specifically for high-altitude and cold regions, have relatively complex installation steps, and require a large investment of manpower and time.

The first installation shell and the second installation shell slide on the upper and lower sides of the water meter, respectively. The first installation shell and the second installation shell are provided with connecting components on the left and right sides. The first installation shell and the second installation shell are fixed with a bottom shell on the side near the outer shell. The two bottom shells are threaded with two fixing bolts on the side near the outer shell.

[0005] Preferably, the antifreeze mechanism includes a fan, which is installed on the side of the second mounting shell away from the first mounting shell. Multiple evenly distributed heating tubes are installed inside the side of the second mounting shell away from the first mounting shell. A heater is installed at the bottom of each heating tube. An electric wire is installed on the side of the heater away from the heating tube. A ventilation plate is installed on the side of the first mounting shell away from the second mounting shell.

[0006] Preferably, both insulation mechanisms include insulation block one, and the two insulation blocks one are respectively installed on the opposite side of the mounting shell one and the mounting shell two, and insulation block two is installed on the opposite side of the two insulation blocks one.

[0007] Preferably, the connecting assembly includes a connecting block one and a connecting block two. The connecting block one is installed on the side of the mounting shell one near the mounting shell two, and the connecting block two is installed on the side of the mounting shell two near the mounting shell one. A connecting rod is installed on the side of the connecting block two near the connecting block one, and a right-angled trapezoidal block one is installed on the side of the connecting rod away from the connecting block two. A pull rod is slidably connected inside the connecting block one. A limit plate is installed on the side of the pull rod near the connecting block two, and a spring is installed on the side of the limit plate near the pull rod. The right-angled trapezoidal block two is installed on the side of the limit plate away from the pull rod, and a pull block is installed on the side of the pull rod away from the limit plate.

[0008] Preferably, the two insulation blocks are positioned opposite each other and abut against the side of the water meter closest to the outer casing.

[0009] Preferably, the fan is electrically connected to the integrated sensor, and the end of the wire away from the heater is installed on the side of the integrated sensor closer to the water meter.

[0010] Preferably, the side of the second right-angled trapezoidal block away from the limiting plate is slidably connected to the side of the first right-angled trapezoidal block near the second right-angled trapezoidal block, and the side of the second right-angled trapezoidal block away from the connecting block is slidably connected to the side of the first right-angled trapezoidal block near the connecting block.

[0012] This invention provides a freeze-proof and heat-insulating device for water meters in high-altitude and cold regions. It has the following beneficial effects: 1. This invention features an ingeniously designed installation mechanism. The first and second installation shells can be easily slid into the water meter. The connecting components, through the cooperation of pull blocks, pull rods, and other parts, enable quick connection and disassembly. The operation is simple and convenient. The bottom shell and fixing bolts can firmly fix the installation mechanism to the outer shell. This not only facilitates the initial installation of the water meter, but also allows for quick and convenient operation during later maintenance, repair, or replacement of the water meter. This greatly improves the practicality and maintainability of the device, reduces maintenance costs and time, and provides convenience for the management and maintenance of water meters in high-altitude and cold regions.

[0013] 2. This invention monitors the internal temperature of the device in real time by integrating sensors. When the temperature is lower than the set value, the fan and heater are quickly activated. The fan promotes the uniform circulation of heat generated by the heating element, accurately providing a suitable temperature for the water meter. This effectively prevents the water inside the water meter from freezing, avoiding problems such as inaccurate metering and damage caused by freezing. It ensures that the water meter can stably and accurately measure water consumption in cold environments, guaranteeing the normal water demand of residents and the water supply system.

[0014] 3. This invention, through the close cooperation of insulation block one and insulation block two, fully wraps the water meter to form a highly efficient heat insulation layer, which significantly reduces the heat exchange between the water meter and the cold external environment, allowing the internal heat of the water meter to be maintained for a long time, effectively keeping the water meter in a suitable temperature state, reducing the impact of low temperature caused by heat loss, and further improving the antifreeze performance of the water meter.

The ventilation grille 10 is used to provide good air exchange capacity inside the outer shell 1, so that the air flow inside the outer shell 1 remains unobstructed. The valve 11 is used to control the flow and cut off of water in the pipe.

[0019] The installation mechanism 3 includes a first installation shell 301 and a second installation shell 302. The first installation shell 301 and the second installation shell 302 slide on the upper and lower sides of the water meter 2, respectively. The first installation shell 301 and the second installation shell 302 are provided with connecting components 4 on the left and right sides. The first installation shell 301 and the second installation shell 302 are fixed with a bottom shell 303 on the side near the outer shell 1. The two bottom shells 303 are threaded with two fixing bolts 304 on the side near the outer shell 1.

[0020] In this invention, mounting shell 1 301 and mounting shell 2 302 are used to install and connect the antifreeze mechanism 6 and the protection mechanism. The base plate 303 is used to connect the mounting shell to the inner wall of the outer shell 1, and the fastening bolt 304 is used to connect the base plate 303 to the inner wall of the outer shell 1. The bolt connection provides a stable fixing effect, so that mounting shell 1 301 and mounting shell 2 302 can be installed inside the outer shell 1, thereby enabling better connection of other components.

[0021] Please see the appendix Figure 1 - Appendix Figure 2 The antifreeze mechanism 6 includes a fan 601, which is installed on the side of the second mounting housing 302 away from the first mounting housing 301. Multiple evenly distributed heating tubes 602 are installed inside the side of the second mounting housing 302 away from the first mounting housing 301.

[0023] Please see the appendix Figure 5 Both insulation mechanisms 5 include insulation block 1 501. The two insulation blocks 1 501 are respectively installed on the opposite side of mounting shell 1 301 and mounting shell 2 302. Insulation block 2 502 is installed on the opposite side of the two insulation blocks 1 501. The opposite side of the two insulation blocks 2 502 abuts against the side of the water meter 2 near the outer shell 1.

[0024] In this invention, the insulation mechanism 5 consists of insulation block 1 501 and insulation block 2 502. The two insulation mechanisms 5 are respectively set on the opposite side of mounting shell 1 301 and mounting shell 2 302, and together provide all-round insulation for water meter 2. Insulation block 1 501 is made of high-quality polyurethane foam material, which has an extremely low thermal conductivity and can effectively prevent heat transfer. The shape of insulation block 1 501 is customized according to the internal space of mounting shell 1 301 and mounting shell 2 302 to ensure a tight fit without gaps. Insulation block 2 502 is installed on the opposite side of the two insulation blocks 1 501. Insulation block 2 502 is made of polystyrene foam board, and its surface is covered with a layer of aluminum foil. The aluminum foil can reflect heat and further improve the insulation efficiency. The shape design of insulation block 2 502 matches the curved surface of the water meter 2 near the outer shell 1, which can better fit the water meter 2 and reduce heat loss.

[0025] Please see the appendix Figure 4 The connecting component 4 includes a first connecting block 401 and a second connecting block 402. The first connecting block 401 is installed on the side of the first mounting shell 301 near the second mounting shell 302, and the second connecting block 402 is installed on the side of the second mounting shell 302 near the first mounting shell 301. A connecting rod 403 is installed on the side of the second connecting block 402 near the first connecting block 401, and a right-angled trapezoidal block 404 is installed on the side of the connecting rod 403 away from the second connecting block 402. A pull rod 405 is slidably connected inside the first connecting block 401, and a limit plate 407 is installed on the side of the pull rod 405 near the second connecting block 402. A spring 406 is installed. A right-angled trapezoidal block 408 is installed on the side of the limiting plate 407 away from the pull rod 405. A pull block 409 is installed on the side of the pull rod 405 away from the limiting plate 407. The spring 406 is sleeved on the outer periphery of the pull rod 405. The end of the spring 406 away from the limiting plate 407 is installed inside the connecting block 401. The side of the right-angled trapezoidal block 408 away from the limiting plate 407 is slidably connected to the side of the right-angled trapezoidal block 404 near the right-angled trapezoidal block 408. The side of the right-angled trapezoidal block 408 away from the connecting block 402 is slidably connected to the side of the right-angled trapezoidal block 404 near the connecting block 402.

[0026] In this invention, a pull rod 405 is slidably connected inside the connecting block 401. The pull rod 405 is made of high-strength plastic material, possessing a certain degree of flexibility and wear resistance. A limiting plate 407 is installed on the side of the pull rod 405 near the connecting block 402. The size of the limiting plate 407 is slightly larger than the sliding channel inside the connecting block 401 to prevent the pull rod 405 from dislodging from the connecting block 401. A spring 406 is installed on the side of the limiting plate 407 near the pull rod 405. The spring 406 is made of high-strength stainless steel, possessing good elasticity and durability. 406 is sleeved on the outer periphery of the pull rod 405, with one end fixed to the limiting plate 407 and the other end installed inside the connecting block 401. A right-angled trapezoidal block 408 is installed on the side of the limiting plate 407 away from the pull rod 405. The right-angled trapezoidal block 408 and the right-angled trapezoidal block 404 cooperate to achieve the locking function. A pull block 409 is installed on the side of the pull rod 405 away from the limiting plate 407. The shape of the pull block 409 is designed to facilitate user operation. By pulling the pull block 409, the movement of the pull rod 405 can be controlled, thereby realizing the locking and unlocking operation of the connecting component 4.

[0027] Working principle: The integrated sensor 7 continuously monitors the internal ambient temperature of the device. When the temperature drops to the set antifreeze temperature point, it transmits a signal to the electrically connected fan 601 and heater 603 to activate the antifreeze protection mechanism. The heater 603 is powered on and provides heat to the heating tube 602, causing the heating tube 602 to heat up. The air inside the housing 302 is heated by the heat radiation from the heating tube 602. After receiving the signal, the fan 601 starts to run and blows the heated air toward the water meter 2. When the hot air passes over the surface of the water meter 2, it transfers heat to the water meter 2 to prevent the water in the water meter 2 from freezing due to low temperature. Insulation block 2 502 and insulation block 1 501 can effectively reduce the heat exchange between water meter 2 and the external environment, prevent heat loss, and further enhance the heat preservation effect of water meter 2. Combined with heating circulation, they can better maintain water meter 2 within a suitable temperature range. When installing water meter 2, slide mounting shell 1 301 from above water meter 2 and mounting shell 2 302 from below water meter 2 onto the outer periphery of water meter 2. Then, connect and fix them through connecting component 4. Align right trapezoidal block 1 404 on connecting rod 403 on one side of connecting block 2 402 with connecting block 1 401. Pull pull block 409, which drives pull rod 405 to move outward. Limit plate 407 on pull rod 405 compresses spring 406, and at the same time moves right trapezoidal block 2 408. Then, right trapezoidal block 1 404 enters the interior of connecting block 1 401. Release pull block 409, spring 406 rebounds, and pushes right trapezoidal block 2 408 to lock with right trapezoidal block 1 404, thus completing the connection between mounting shell 1 301 and mounting shell 2 302.

[0028] Next, the two bottom shells 303 are brought close to the outer shell 1, and the mounting mechanism 3 is firmly fixed to the outer shell 1 by the threaded fixing bolts 304, so that the water meter 2 is stably installed inside the outer shell 1, ensuring that the heat preservation and antifreeze device can effectively play its role around the water meter 2. The temperature display screen 9 displays the temperature inside the outer shell 1 in real time, so that users can understand the internal temperature status of the device at any time. The vent grille 10 ensures proper air exchange between the inside and outside of the outer shell 1, making temperature monitoring and regulation more accurate. The valve 11 is used to control the flow and cut-off of water in the pipe connected to the water meter 2, which is convenient for operation during maintenance, repair or other needs.
