The device comprises an active heat preservation assembly and a passive heat preservation assembly. The active heat preservation assembly comprises a heat preservation box, an active heating box, a water supply pipe, a mounting cylinder and a lime column. The active heating box is fixedly arranged at the bottom of the outer wall of the heat preservation box. Through the active heat preservation assembly and the passive heat preservation assembly, firstly, under the daily heat preservation condition and in the low-temperature environment with a low intensity, the residual heat in the water supply pipe is used to collect and reuse the residual heat of the water meter, so that the internal pipeline of the water meter is prevented from being frozen. Secondly, when the temperature decreases to a situation that the passive heat preservation assembly cannot cope with, the active heat preservation assembly is used to make the lime column continuously generate heat.

Description

Technical Field

[0001] This invention belongs to the field of water meter technology, specifically relating to a water meter protection device and its control system for extremely cold weather. Background Technology

[0002] A water meter is an instrument used to measure water flow. Most of them measure the cumulative flow of water. They are generally divided into two categories: volumetric water meters and velocity water meters. Originating in the UK, water meters have been developed for nearly two hundred years. When selecting a water meter, you should first estimate the flow rate and range you usually use, and then choose the water meter with the closest commonly used flow rate as your first choice.

[0003] Extreme cold, also known as extreme cold weather, refers to the degree of coldness in winter temperatures. The term "extreme cold" as defined and listed in meteorological books should be an abbreviation for "extremely cold weather," "extremely cold meteorological environment," or "extremely cold temperature environment." The degree of coldness in winter has always been a concern for people and is often measured in degrees Celsius, such as -4 degrees Celsius or -10 degrees Celsius.

[0004] With continued economic development, the demand for mineral resources and domestic water use is increasing. In actual production and daily life, it has been found that water meters frequently freeze. Current technology ensures that the water temperature is between 4 and 7 degrees Celsius during water supply to prevent water from freezing in the pipes. However, the water pipes entering homes cannot guarantee a constant flow of water. Therefore, people still turn on the taps when not using water to avoid freezing the pipes. However, in extremely cold conditions, many water pipes still freeze and burst. Subsequent measures such as wrapping the water pipes do not alleviate the freezing problem. Summary of the Invention

[0005] The purpose of this invention is to provide a water meter protection device and its control system for extremely cold weather, which aims to solve the problems of sealing and leakage warning.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A water meter protection device for extremely cold weather includes an active insulation component and a passive insulation component. The active insulation component includes an insulation box, an active heating box, a water supply pipe, an installation cylinder, and a lime column. The active heating box is fixedly installed at the bottom of the outer wall of the insulation box. Two installation cylinders are provided, fixedly installed on both sides of the bottom of the outer wall of the insulation box, and installation holes are provided on both sides of the bottom of the inner wall of the insulation box. The bottom end of the water supply pipe is connected to the center of the top of the outer wall of the installation cylinder through the installation holes. The lime column is rotatably embedded in the inner wall of the installation cylinder.

[0008] The passive insulation component includes a passive heating box, a circulation pipe, a protective ring, a sleeve, a water meter, and a T-connector. There are two passive heating boxes, which are respectively connected and installed on both sides of the outer wall of the insulation box. The water meter is embedded in the inner wall of the insulation box and is connected to the T-connector. The output end of the T-connector is connected to the circulation pipe through a diverter pipe and a flexible hose. The protective ring is connected and installed at the center of both sides of the outer wall of the insulation box. The sleeve is fitted onto the output end of the water meter.

[0009] Furthermore, the sleeve and the tee pipe are connected by a hose and a valve.

[0010] Furthermore, a padding layer is bonded to one side of the bottom of the inner wall of the insulated box, and the outer wall of the padding layer is attached to the top of the outer wall of the water meter.

[0011] Furthermore, a heat dissipation block is fixedly installed on the inner wall of the passive heating box, and one side of the outer wall of the heat dissipation block is attached to one side of the outer wall of the circulation pipe. A sealing plate is slidably embedded on the top of the outer wall of the insulation box, and a pressure pipe is connected to one side of the outer wall of the active heating box.

[0012] A control system for a water meter protection device for extreme cold weather, using any one of the above-mentioned water meter protection devices for extreme cold weather, includes:

[0013] The control planning module is used for temperature control management and data processing.

[0014] Active insulation module, used to improve insulation performance in extremely cold conditions;

[0015] Passive insulation modules are used for insulation work in general extremely cold conditions;

[0016] The valve drive module is used to switch between active and passive insulation valves.

[0017] The control planning module, the active insulation module, and the passive insulation module are connected by bidirectional signals, and the control planning module is connected by bidirectional signals to the valve drive module.

[0018] Furthermore, the planning module includes a switching module, a prompting module, and a data storage module.

[0019] Furthermore, the active heat preservation module includes a material supply calibration module, a water supply valve module, and a pressure control module.

[0020] Furthermore, the passive insulation module includes a circulating water supply valve module, a temperature detection module, and a water meter detection module.

[0021] Furthermore, the valve drive module includes a valve status update module and a data transceiver module.

[0022] Furthermore, the water supply valve module is used to control the water supply to the active insulation module.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In this solution, active and passive insulation components are used. First, under normal insulation conditions and in environments with low temperatures, the residual heat inside the water supply pipes is continuously collected and reused to prevent the water meter's internal pipes from freezing. Second, when the temperature drops to a level that the passive insulation components cannot handle, the active insulation components are used to control the water supply, allowing the lime column to continuously generate heat. When the lime column fails, the passive insulation components reuse the residual heat to prevent heat loss. In actual working environments, polyurethane or similar insulation materials are still required to wrap the insulation box to ensure sufficient insulation. Attached Figure Description

[0040] Please see Figure 1-7 The technical solution provided in this embodiment is as follows:

[0041] A water meter protection device for extremely cold weather includes an active insulation component and a passive insulation component. The active insulation component includes an insulation box 1, an active heating box 3, a water supply pipe 9, an installation cylinder 10, and a lime column 11. The active heating box 3 is fixedly installed at the bottom of the outer wall of the insulation box 1. Two installation cylinders 10 are provided, and the two installation cylinders 10 are fixedly installed on both sides of the bottom of the outer wall of the insulation box 1. Installation holes are opened on both sides of the bottom of the inner wall of the insulation box 1. The bottom end of the water supply pipe 9 is connected to the center of the top of the outer wall of the installation cylinder 10 through the installation holes. The lime column 11 is rotatably embedded in the inner wall of the installation cylinder 10.

[0042] The passive insulation component includes a passive heating box 2, a circulation pipe 4, a protective ring 7, a sleeve 13, a water meter 14, and a three-way pipe 15. There are two passive heating boxes 2, which are respectively connected and installed on both sides of the outer wall of the insulation box 1. The water meter 14 is embedded in the inner wall of the insulation box 1 and is connected to the three-way pipe 15. The output end of the three-way pipe 15 is connected to the circulation pipe 4 through a diverter pipe and a flexible hose. The protective ring 7 is connected and installed at the center of both sides of the outer wall of the insulation box 1. The sleeve 13 is sleeved on the output end of the water meter 14.

[0043] In a specific embodiment of the present invention, the active insulation component can insulate the water meter 14 and the water supply pipe 9 in extremely cold environments. This also prevents the pipe's internal circulation from decreasing due to prolonged periods without water use, and avoids the passive insulation component failing, which could cause the stagnant water inside the pipe to freeze. Secondly, the passive insulation component can provide insulation under normal conditions. In extremely cold regions, waterworks typically heat the water source to a certain extent to maintain a temperature of 5-7 degrees Celsius. The residual heat generated during this process can be reused. The insulation box 1, the active heating box 3, and the passive heating box 2 can effectively achieve the insulation effect. However, in actual processing, a vacuum structure is required to further enhance the insulation effect. The part of the active heating box 3 connected to the insulation box 1 does not use a vacuum structure to facilitate heat transfer.

[0045] In a specific embodiment of the present invention, the sleeve 13 and the three-way pipe 15 are connected by a hose and a valve, which can divert circulating water containing heat from the water supply pipe 9, and ensure the insulation of the connection between the sleeve 13 and the water meter 14 and the three-way pipe 15.

[0046] Specifically, a pad 12 is bonded to one side of the bottom of the inner wall of the insulated box 1, and the outer wall of the pad 12 is attached to the top of the outer wall of the water meter 14.

[0047] In a specific embodiment of the present invention, the padding layer 12 can ensure that water droplets do not condense on the outer wall of the water meter 14, thus preventing freezing.

[0048] Specifically, a heat dissipation block 5 is fixedly installed on the inner wall of the passive heating box 2, and one side of the outer wall of the heat dissipation block 5 is attached to one side of the outer wall of the circulation pipe 4. A sealing plate 6 is slidably embedded on the top of the outer wall of the heat preservation box 1, and a pressure pipe 8 is connected to one side of the outer wall of the active heating box 3.

[0049] In a specific embodiment of the present invention, the heat dissipation block 5 can improve the efficiency of heat dissipation and the heat preservation effect, and the circulation pipe 4 can realize the circulation of heat components.

[0050] The control system of the water meter protection device for extreme cold weather according to claim 1 uses the water meter protection device for extreme cold weather according to claims 1-4, comprising:

[0051] Control planning module 16 is used for temperature control management and data processing;

[0052] The active insulation module 17 is used to improve the insulation effect in extremely cold conditions;

[0053] Passive insulation module 18 is used for insulation work under general severe cold conditions;

[0054] Valve drive module 19 is used to switch between active and passive insulation valves;

[0055] The control planning module 16, the active insulation module 17, and the passive insulation module 18 are connected by bidirectional signals, and the control planning module 16 is connected by bidirectional signals to the valve drive module 19.

[0056] In a specific embodiment of the present invention, the bidirectional signal connection between the control planning module 16, the active insulation module 17 and the passive insulation module 18 can realize the switching and activation of the active insulation and passive insulation functions. The bidirectional signal connection between the control planning module 16 and the valve drive module 19 can assist in the management of the valve, avoid erroneous operation, and improve the accuracy of use.

[0057] Specifically, the control planning module 16 includes a switching module, a prompting module, and a data storage module.

[0058] In a specific embodiment of the present invention, the function switching between active heat preservation and passive heat preservation is realized by using a switching module.

[0059] Specifically, the active insulation module 17 includes a material supply calibration module, a water supply valve module, and a pressure control module.

[0060] In a specific embodiment of the present invention, the water supply can be managed through the feeding calibration module, and the pressure control module assists the active heating box 3 in depressurizing to avoid pressure rise during heating.

[0061] Specifically, the passive insulation module 18 includes a circulating water supply valve module, a temperature detection module, and a water meter detection module.

[0062] In a specific embodiment of the present invention, a circulating water supply valve module is used to control the function of the circulating pipe 4.

[0063] Specifically, the valve drive module 19 includes a valve status update module and a data transceiver module.

[0064] In a specific embodiment of the present invention, the valve status update module can ensure the working efficiency of the valve, avoid erroneous opening, and improve the accuracy of operation.

[0065] Specifically, the water supply valve module is used to control the water supply to the active insulation module 17.

[0066] In a specific embodiment of the present invention, the water supply valve module can ensure precise control of the valve.

[0067] The working process of the water meter protection device and its control system for extremely cold weather provided by this invention is as follows:

[0068] First, install the insulation box 1 in the designated working position. Connect the three-way pipe 15 to all components requiring circulating water, such as the circulation pipe 4, the sleeve 13, and the water supply pipe 9. All connections must be controlled by solenoid valves, with control granted to the valve drive module 19. Then, the control planning module 16 monitors the internal temperature of the insulation box 1 in real time. Water is diverted through the three-way pipe 15, flowing into the circulation pipe 4 and the sleeve 13, and then returning to the water supply pipe 9. Subsequently, during use, if the water in the pipes becomes stagnant due to prolonged periods without water use, or if the passive insulation components are unable to withstand extremely cold weather, the system can be switched using the appropriate module. Activate the active heat preservation component and open the valve connected to the water supply pipe 9 to allow water to enter the top of the lime column 11. The lime column 11 is made of quicklime packaged in pressed non-woven fabric. The quicklime and water generate heat. Control the water flow in the water supply pipe 9 to ensure the heating time. Once the quicklime reaction is complete, the generated residual heat and the passive heat preservation component are used for continuous heat preservation. When the temperature drops below zero degrees Celsius, start the next water supply pipe 9 and use a new lime column 11 for heating. In actual use, there may be a problem of the water supply pipe 9 being idle. A circulation pump can be used to assist the circulation pipe 4 and the sleeve 13 in water circulation to ensure heat collection.

[0069] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
