Description

Technical Field

[0001] The invention relates to the technical field of water meter boxes, in particular to a solar energy storage type heating antifreeze water meter box. Background Art

[0002] The antifreeze water meter box is mainly for some high-cold areas and tap water units in the north. The freezing of water meters is a problem that every tap water company is troubled by and has no solution to. The previous ideas for dealing with it were, first, burying the water meter underground (installing the water meter about one meter underground, using geothermal heat to ensure that the water meter is not frozen). The second is to choose an antifreeze water meter box, but the water meter boxes on the market currently simply add an antifreeze layer, but under the condition of continuous low temperature, freezing will still occur. As a result, the maintenance workload of the water supply unit is huge, and the loss is difficult to estimate. The trouble caused by the buried water meter is that it is inconvenient to read the meter, it is difficult for the staff to read the meter and there are safety hazards. The loss or damage of the water meter well will cause safety hazards to passers-by, especially at night and drunk people. Every year, pedestrians fall into the buried meter well, and then seek compensation or lawsuits from the tap water company. Now the automation is gradually improving, and the application of smart water meters is increasing. If the water meter is installed underground, the moisture will greatly shorten the service life of the water meter and increase the operating cost of the tap water company.

[0003] Traditional water meter boxes are often unable to effectively prevent water meters and water pipes from freezing and cracking in cold weather because they lack effective built-in heating or antifreeze systems. Many traditional systems rely on external power supplies or require manual intervention to protect water meters from freezing damage, and require regular manual inspection and maintenance, especially in winter. Frequent monitoring and maintenance are required to prevent freezing and damage. Traditional water meter boxes often cannot automatically adjust their operating modes according to environmental changes, and are not flexible enough to respond to changes in wind and temperature. In many ordinary water meter box designs, anti-rust and anti-corrosion measures are insufficient, especially in rainy or humid environments, where water meters and pipes are prone to rust and corrosion. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a solar energy storage type heating antifreeze water meter box, which solves the problems that traditional water meter boxes lack effective antifreeze, automatic adjustment and anti-corrosion systems under harsh climatic conditions, require external power supply and frequent manual maintenance, and are susceptible to environmental corrosion.

[0015] Working principle: First of all, the water meter box is different from the ordinary deep-buried water meter box. Its box shell is set outdoors. The photovoltaic power storage mechanism installed on the top of the water meter box is used in conjunction with long-term outdoor sunlight to provide the electricity needed for the heating and antifreeze mechanism to work. At the same time, the wind force of the air that may be formed at any time outdoors is used to drive the unpowered driving mechanism to operate. At the same time, the discharge guide mechanism is used to suck the paste anti-rust liquid stored in the storage tank, and toward the valved water pipes and resin dial water meters that are the main working inside the water meter box. The paste's adhesion is used to make the outer surfaces of the valved water pipes and the resin dial water meters able to adhere to the rust-proof anti-rust liquid in real time. At the same time, when the outdoor wind drives the unpowered driving mechanism to operate, it generates circulating wind inside the box shell, which generates the anti-rust liquid generated by the heating and antifreeze mechanism. The hot air is transported to the surface of the valved water pipe and the resin dial water meter to prevent the valved water pipe and the resin dial water meter from being frozen and damaged in a low temperature environment. The box shell included in this water meter box is responsible for installing the valved water pipe and the resin dial water meter for measuring the water pipe flow rate. The box shell is installed in the open outdoors by anchoring. The valved water pipe itself is equipped with a gate valve that can be cut off and opened. Multiple groups of valved water pipes and corresponding resin dial water meters are arranged in a longitudinal distribution inside the box shell, and the anti-rust spraying mechanism located inside the box shell corresponds to the installation status of the valved water pipe and the resin dial water meter. The uniform sprinkler assembly contained therein is also arranged in a longitudinal arrangement inside the box shell, and is crossed between adjacent valved water pipes to ensure that the uniform sprinkler assembly can always be maintained. Above the valved water pipe and the resin dial water meter, the suction pipe included in the anti-rust spraying mechanism extends to the interior of the storage tank. At the same time, the groove installed at the bottom can make the paste anti-rust liquid inside the storage tank converge inside the valved water pipe and pass through the water flow. When it is transported through the resin dial water meter, the resin dial water meter is used to detect the flow rate of the water flow. At the same time, the storage tank installed at the bottom of the box shell is pre-filled with the paste anti-rust liquid not higher than the height of the exhaust grille. The exhaust grilles installed on both sides of the storage tank and at the top have a trapezoidal discharge hood structure. While discharging the air inside the box shell, it blocks the external environmental water from entering the box shell, thereby avoiding the contamination of the paste anti-rust liquid. The suspension frame installed on the top of the box shell is used to fix the photovoltaic The photovoltaic power storage mechanism includes an inclined bracket with a conical structure at the top. By utilizing its structural characteristics, the photovoltaic panels that receive light in an inclined manner can be installed in a relative manner on both sides to improve the efficiency of light-receiving power generation. The electricity generated by the photovoltaic panels is received and stored by the energy storage batteries included in the photovoltaic power storage mechanism. When the water meter is operating in normal weather, there is no need to supply power to the heating and antifreeze mechanism through the photovoltaic power storage mechanism, and the unpowered drive mechanism operates in real time according to the ambient wind conditions of the outdoor installation. The unpowered drive mechanism includes a large-diameter shaft sleeve on the outside of the small-diameter shaft column, and both are restricted to rotate inside the casing by two sets of bearings installed on the suspension frame. The small-diameter shaft column and the large-diameter shaft sleeve each extend out of the casing and are located in the suspension frame. A set of unpowered fan blades are installed.The blades of the unpowered fan blades are of an arc-shaped V-shaped structure to achieve unilateral wind reception, and the ambient wind will simultaneously drive the small-diameter shaft column and the unpowered fan blades corresponding to the large-diameter shaft sleeve to rotate, so that the small-diameter shaft column and the large-diameter shaft sleeve can rotate at any time in an unpowered manner according to the outdoor ambient wind. The exhaust fan blades installed on the large-diameter shaft sleeve inside the casing synchronously follow the large-diameter shaft sleeve, and form a blowing flow of air inside the casing and toward the valved water pipe and the resin dial water meter, while the small-diameter shaft column drives the spiral conveying blades installed inside the casing to rotate inside the suction pipe and the small-diameter guide pipe included in the anti-rust spraying mechanism, so that the paste-like anti-rust liquid stored in the storage tank is also drawn into the suction pipe and the small-diameter guide pipe. Due to the inner wall diameter of the small-diameter guide pipe The diameter of the spiral conveying blade is smaller than the suction pipe, so that the outer ring diameter of the spiral conveying blade inside the suction pipe is larger than the outer ring diameter inside the small-diameter guide pipe, and the diameter gradually decreases from bottom to top. After the paste anti-rust liquid enters the small-diameter guide pipe, the passing area is reduced, thereby increasing the conveying pressure, so that the paste anti-rust liquid is sent into each uniform sprinkler assembly along the small-diameter guide pipe in a pressurized form by the spiral conveying blade, and the two-way conveying pipe included in the uniform sprinkler assembly is arranged on both sides of the small-diameter guide pipe. The paste anti-rust liquid enters the two-way conveying pipe through the small-diameter guide pipe, and then enters the frame pipe of the rectangular frame structure through the two-way conveying pipe. The frame pipe is always located above the valved water pipe and the resin dial water meter. The pressurized anti-rust liquid enters and flows along the frame pipe. The dripping anti-rust paste liquid falls to the discharge guide mechanism. The V-shaped guide plate included in the discharge guide mechanism is a V-shaped structure. The inclined plate structures on both sides can realize the diversion of air and the anti-rust paste liquid. At the same time, the return inclined plates installed on both sides of the box shell can change the flow direction of the air when they come into contact with the circulating air directly, so that the air is blown back into the box shell. The anti-rust paste liquid dripping on the V-shaped guide plate re-enters the storage tank along the gap reserved between the V-shaped guide plate and the inner wall of the box shell. The unpowered driving mechanism circulates and draws in the anti-rust paste liquid and sprays it on the water pipe with valve and the resin dial water meter, thereby utilizing the ambient wind to continuously provide anti-rust protection for the water pipe with valve and the resin dial water meter in an unpowered manner. The antifreeze locking structure contained in the unpowered driving mechanism operates following the small-diameter shaft column. The linkage disk contained in the uniform sprinkler assembly is installed on the top of the small-diameter shaft column and rotates following the small-diameter shaft column. A circle of arc-shaped tooth keyways is provided on the outer ring of the linkage disk, and the component box contained in the uniform sprinkler assembly is installed on the suspension frame. A sliding extension strip is installed in the water storage cavity opened therein. In order to prevent the extension strip from sliding out of the water storage cavity, a chuck is installed at one end of the extension strip located inside the water storage cavity, and an arc-shaped key is installed at the end of the extension strip facing the linkage disk.The arc angle of the arc key can be exactly embedded in the arc keyway, and three-quarters of the water is stored in the water storage chamber. Under normal room temperature, the linkage disk drives the arc keyway to rotate, and the arc keyway will push the arc key and the extension strip to rotate along the inner wall of the water storage chamber. The retaining spring installed between the chuck and the inner wall of the water storage chamber is compressed and squeezed by the displacement of the chuck, so that the arc key can be attached to the linkage disk at any time and engage the arc keyway at any time. In the cold weather in winter, the thermal conductive copper extended on the side wall of the water storage chamber The copper sheet will transfer the low temperature outside to the water temporarily stored in the water storage chamber. When the freezing temperature is reached, the temperature conducted by the heat-conducting copper sheet will drive the water temporarily stored in the water storage chamber to freeze and form a solid locking state that wraps around the extension strip, the chuck and the retaining spring, so that the extension strip is frozen and locked by ice and cannot operate. The arc-shaped key at the outer end of the extension strip is also meshed and locked in the arc-shaped tooth keyway, driving the linkage disk, the small-diameter shaft column and the corresponding unpowered fan blades to be unable to rotate with the circulation of the ambient wind. At the same time, the spiral conveying blades and And the overall anti-rust spraying mechanism, thereby automatically shutting down the anti-rust liquid spraying operation in a low-temperature environment, preventing the attached anti-rust liquid from freezing on the outer surface of the valved water pipe and the resin dial water meter due to the low-temperature environment, thereby causing damage to the valved water pipe and the resin dial water meter, and the large-diameter shaft sleeve and its corresponding fixed non-powered fan blades and exhaust fan blades will not be affected by the antifreeze locking component, and continue to form air flow ventilation force inside the box shell. In a low-temperature environment, the energy storage battery contained in the photovoltaic power storage mechanism synchronously turns on the heating antifreeze mechanism located inside the box shell, driving the heating antifreeze mechanism The included heating wire generates high-temperature air above the interior of the box shell, and pushes the hot air toward the heating wire along the wind force formed by the exhaust fan blades, blowing the hot air to the valved water pipe and the resin dial water meter, and blowing it back along the return ramp, so that in the low-temperature environment outside, the interior of the box shell can form a continuous hot air circulation state through solar photovoltaic power supply, reducing the risk of freezing and cracking of the valved water pipe and the resin dial water meter when working in a low-temperature environment. The hot air will be guided along the ramps on both sides of the V-shaped guide plate, and finally discharged from the exhaust grilles installed on both sides of the storage tank. ,

[0016] The present invention provides a solar energy storage type heating antifreeze water meter box. It has the following beneficial effects: 1. The present invention has efficient energy utilization and self-sufficient energy: by adopting photovoltaic panels to capture sunlight and convert it into electrical energy, the photovoltaic power storage mechanism not only optimizes energy use and reduces dependence on external power sources, but also improves the light receiving efficiency of the photovoltaic panels through the conical design of the inclined bracket, thereby enhancing the efficiency of energy capture and conversion. In a low-temperature environment, the electric energy provided by the photovoltaic power storage mechanism activates the heating and antifreeze mechanism to generate the necessary heat to prevent the water meter and pipe from freezing. This thermal management system converts solar energy into electrical energy, reducing dependence on the traditional power grid. At the same time, the circulation of hot air is optimized through the exhaust fan blades and the return inclined plate. This integrated energy solution enables the equipment to work stably in a low-temperature environment.

[0017] 2. Optimized physical structure design of the present invention: The longitudinal arrangement of the anti-rust spray mechanism and the uniform sprinkler assembly inside the housing and their cross-layout ensure full coverage of the valved water pipes and the resin dial water meter, thereby providing continuous and effective anti-rust protection. This layout design makes full use of the space while ensuring the uniformity of the spray coverage. The storage tank at the bottom of the housing is designed to store the paste anti-rust liquid. In addition, the design of the suspension frame and the exhaust grille at the top of the housing effectively blocks the intrusion of external water and impurities, protects the purity of the internal machinery and the anti-rust liquid, reduces maintenance requirements and ensures the long-term operation efficiency of the system.

[0018] 3. Intelligent and automated features of the present invention: Through the automated spraying mechanism and energy management system, and through the carefully designed blade structure and bearing configuration, the unpowered drive mechanism can efficiently convert ambient wind energy into mechanical motion, reducing the need for human intervention and improving operational efficiency and reliability. The automated anti-rust and heating systems reduce the workload of daily maintenance, while enhancing the sustainability and economy of the system.

[0019] 4. The present invention has an intelligent freezing prevention mechanism: in extremely cold weather, the locking structure of the linkage disk and the extension strip automatically locks, suspending the movement of the unpowered mechanism to prevent the frozen paste-like anti-rust liquid from causing damage to the pipes and water meters. The intelligent locking feature of this design prevents mechanical damage and reduced efficiency when operating at low temperatures. The design of the system not only optimizes energy use and reduces environmental impact, but also reduces maintenance requirements and operating costs through intelligent design. In addition, the efficient integration of the automated spraying mechanism and the thermal management system ensures continuous anti-rust protection and anti-freeze functions without frequent manual intervention.

By utilizing its structural characteristics, the inclined light-receiving photovoltaic panel 52 can be installed in a relative manner on both sides to improve the efficiency of light-receiving power generation. The electricity generated by the photovoltaic panel 52 is contained in the photovoltaic power storage mechanism 5. The energy storage battery 53 contained therein receives and stores the energy. When the water meter is operating in normal weather, there is no need to supply power to the heating and antifreeze mechanism 9 through the photovoltaic power storage mechanism 5. The antifreeze locking structure contained in the unpowered driving mechanism 7 follows the small-diameter shaft column 71 to operate. The linkage disk 74 contained in the uniform sprinkler assembly is installed on the top of the small-diameter shaft column 71 and rotates with the small-diameter shaft column 71. The outer ring of the linkage disk 74 is provided with a circle of arc-shaped tooth key grooves 75, and the component box 77 contained in the uniform sprinkler assembly is installed on the suspension frame 3.

At the same time, the spiral conveying blade 76 and the overall anti-rust spraying mechanism 6 are also stopped synchronously, thereby automatically shutting down the anti-rust liquid spraying operation in the low-temperature environment.The attached anti-rust liquid is prevented from freezing on the outer surface of the valved water pipe 11 and the resin dial water meter 12 due to the low temperature environment, thereby causing damage to the valved water pipe 11 and the resin dial water meter 12. The large-diameter shaft sleeve 72 and its corresponding fixed non-powered fan blades 73 and exhaust fan blades 714 will not be affected by the antifreeze locking component, and continue to form air flow ventilation force inside the box shell 1.

[0025] Please see attached Figure 1 -Attached Figure 8 The anti-rust spraying mechanism 6 is located on the housing 1 and is used to spray the anti-rust liquid paste onto the water meter and the water pipe. The anti-rust spraying mechanism 6 includes a suction pipe 61 and a uniform sprinkler assembly. The suction pipe 61 is fixedly connected to the inside of the housing 1 and extends to the bottom of the storage tank 2. A through notch is provided at the bottom of the suction pipe 61. A small-diameter guide pipe 62 is fixedly connected to the top of the suction pipe 61. The inner diameter of the small-diameter guide pipe 62 is smaller than the inner diameter of the suction pipe 61. The uniform sprinkler assembly is uniformly arranged on the small-diameter guide pipe 62 and crosses between adjacent valved water pipes 11. The uniform sprinkler assembly includes a bidirectional delivery pipe 6 3 and the frame pipe 64, the two-way delivery pipe 63 is arranged on both sides of the small-diameter guide pipe 62, the inner port of the frame pipe 64 is arranged on the port of the two-way delivery pipe 63 away from the small-diameter guide pipe 62, and the bottom wall of the horizontal delivery pipe part of the frame pipe 64 is provided with evenly distributed sprinkler ports 65, and the small-diameter shaft column 71 drives the spiral delivery blade 76 installed inside the box shell 1 to rotate inside the suction pipe 61 and the small-diameter guide pipe 62 included in the rust-proof spraying mechanism 6, so that the paste-like rust-proof liquid stored in the storage tank 2 is also sucked into the suction pipe 61 and the small-diameter guide pipe 62, and the small-diameter shaft column 71 drives the spiral delivery blade 76 installed inside the box shell 1 to rotate inside the suction pipe 61 and the small-diameter guide pipe 62 ... Since the inner wall diameter of the small-diameter guide pipe 62 is smaller than that of the suction pipe 61, the outer ring diameter of the spiral conveying blade 76 located inside the suction pipe 61 is larger than the outer ring diameter located inside the small-diameter guide pipe 62. The diameters gradually decrease from bottom to top. After the paste-like anti-rust liquid enters the small-diameter guide pipe 62, the passing area is reduced, thereby increasing the conveying pressure, so that the paste-like anti-rust liquid is conveyed into each uniform sprinkler assembly along the small-diameter guide pipe 62 by the spiral conveying blade 76 in a pressurized form. The bidirectional conveying pipes 63 included in the uniform sprinkler assembly are arranged on both sides of the small-diameter guide pipe 62. The paste-like anti-rust liquid passes through the small-diameter guide pipe 62. The small-diameter guide pipe 62 enters into the two-way delivery pipe 63, and then enters into the frame pipe 64 of the rectangular frame structure through the two-way delivery pipe 63. The frame pipe 64 is always located above the valved water pipe 11 and the resin dial water meter 12. The pressurized anti-rust liquid flows along the frame pipe 64, and also flows out along the sprinkler port 65 installed at the bottom of the frame pipe 64 toward the valved water pipe 11 and the resin dial water meter 12 until it falls on the valved water pipe 11 and the resin dial water meter 12, and is attached to the valved water pipe 11 and the resin dial water meter 12 in the form of a package.

[0026] Please see attached Figure 1 -Attached Fig.12The unpowered driving mechanism 7 is located on the box shell 1, and cooperates with the wind force of the external environment and the suction pipe 61 and the small-diameter guide pipe 62 to suck the paste anti-rust liquid and form air circulation inside the meter box. The unpowered driving mechanism 7 includes a small-diameter shaft column 71, a large-diameter shaft sleeve 72 and an antifreeze locking component. The small-diameter shaft column 71 is rotatably connected to the top bearing of the suspension frame 3 and extends to the inside of the box shell 1, the small-diameter guide pipe 62 and the suction pipe 61 in turn. The large-diameter shaft sleeve 72 is rotatably connected to the bottom bearing of the suspension frame 3 and extends to the inside of the box shell 1. The tops of the small-diameter shaft column 71 and the large-diameter shaft sleeve 72 are fixedly connected with unpowered fan blades 73. The blades of the unpowered fan blades 73 are set to an arc-shaped V-shaped structure to avoid wind in both directions, and are placed together on the suspension frame 3. Inside, the small-diameter shaft column 71 extends to the side wall of the suction pipe 61 and the small-diameter guide pipe 62, and is fixedly connected with a spiral conveying blade 76. The diameter of the spiral conveying blade 76 located on the inner side of the suction pipe 61 is larger than the diameter of the inner side of the small-diameter guide pipe 62. The large-diameter shaft sleeve 72 extends to the bottom end of the inside of the box shell 1 and is fixedly connected with an exhaust fan blade 714. The exhaust fan blade 714 is located between the heating and antifreeze mechanism 9 and the top wall of the box shell 1.

The component box 77 is fixedly connected to the inner side of the suspension frame 3. The side wall and the output port are facing the linkage disk 74. A water storage chamber 78 is arranged at a position away from the linkage disk 74 inside the component box 77. The water storage chamber 78 is filled with water. The water storage chamber 78 is slidably connected to the side wall of the linkage disk 74 with an extension strip 79. The end of the extension strip 79 facing the linkage disk 74 is fixedly connected with an arc-shaped card key 710. The arc-shaped card key 710 is engaged with the arc-shaped tooth key groove 75. The end of the extension strip 79 located inside the water storage chamber 78 is fixedly connected with a chuck 711. A retaining spring 712 is arranged between the chuck 711 and the inner side wall of the water storage chamber 78. The side wall of the water storage chamber 78 is fixedly connected with a uniformly distributed and through-extending thermal conductive copper sheet 713. When the water meter is operating in normal weather, there is no need to power the heating and antifreeze mechanism 9 through the photovoltaic power storage mechanism 5. , and the unpowered driving mechanism 7 operates in real time according to the ambient wind conditions of the outdoor installation. The small-diameter shaft column 71 included in the unpowered driving mechanism 7 includes a large-diameter shaft sleeve 72 on the outside, and both are restricted to rotate inside the box shell 1 by two sets of bearings installed on the suspension frame 3. The small-diameter shaft column 71 and the large-diameter shaft sleeve 72 each extend out of the box shell 1 and are both located in the suspension frame 3. A set of unpowered fan blades 73 are installed. The blades of the unpowered fan blades 73 themselves are arc-shaped V-shaped structures to achieve unilateral wind reception, and the ambient wind will simultaneously drive the small-diameter shaft column 71 and the unpowered fan blades 73 corresponding to the large-diameter shaft sleeve 72 to rotate, so that the small-diameter shaft column 71 and the large-diameter shaft sleeve 72 can rotate at any time in an unpowered manner according to the outdoor ambient wind.The exhaust fan blade 714 installed inside the large diameter shaft sleeve 72 synchronously follows the large diameter shaft sleeve 72 and forms a blowing flow of air inside the housing 1 and toward the valved water pipe 11 and the resin dial water meter 12. The small diameter shaft column 71 drives the spiral conveying blade 76 installed inside the housing 1 to rotate inside the suction pipe 61 and the small diameter guide pipe 62 included in the anti-rust spraying mechanism 6.

[0027] Please see attached Figure 1 -Attached Figure 8 The discharge guide mechanism 8 is located on the box shell 1 and is used to guide the transportation of hot air and paste anti-rust liquid. The discharge guide mechanism 8 includes a V-shaped guide plate 81 and two sets of oppositely arranged return inclined plates 82. The V-shaped guide plate 81 is fixedly connected to the junction of the box shell 1 and the inner side of the storage tank 2.

The V-shaped guide included in the discharge guide mechanism 8 The guide plate 81 is a V-shaped structure, and the inclined plate structures on both sides can guide the air and the paste-like anti-rust liquid. At the same time, the return inclined plates 82 installed on both sides of the interior of the box shell 1 can change the circulation direction of the air when they come into direct contact with the circulating air, so that the air is blown back into the box shell 1, and the paste-like anti-rust liquid dripping onto the V-shaped guide plate 81 re-enters the storage tank 2 along the gap reserved between the V-shaped guide plate 81 and the inner wall of the box shell 1, so that the unpowered driving mechanism 7 can circulate the paste-like anti-rust liquid and spray it on the valved water pipe 11 and the resin dial water meter 12.

[0028] Please see attached Figure 1 -Attached Figure 7 The heating and antifreeze mechanism 9 is located on the box shell 1, and cooperates with the energy storage battery 53 to generate hot air for antifreeze.

The fixed frame 91 is provided with uniformly distributed heating wires 92, and the heating wires 92 are powered by the cables of the energy storage battery 53. In a low temperature environment, the energy storage battery 53 contained in the photovoltaic power storage mechanism 5 synchronously turns on the heating and antifreeze mechanism 9 located inside the box shell 1, driving the heating wires 92 contained in the heating and antifreeze mechanism 9 to generate high-temperature air above the inside of the box shell 1, and the wind force formed by the exhaust fan blades 714 is pushed toward the direction of the heating wires 92, and the hot air is blown to the valved water pipe 11 and the resin dial water meter 12.
