Description

Technical Field

[0001] The present invention relates to the field of valve technology, and in particular to a valve heating device with improved safety and durability. Background Art

[0002] A valve is a pipeline control component that controls the flow of fluid. It has functions such as diversion, cut-off, throttling, check, diversion or overflow pressure relief. The valve is mainly composed of a valve body, a valve core and a valve handle. The opening and closing of the valve is usually achieved by the valve handle driving the valve core.

[0003] The patent with application number: CN202110984885.3 discloses a water pipe valve that is not easy to freeze in a cold environment, including a handle, a valve stem, a valve shell, a cleaning mechanism, an antifreeze mechanism, a valve pipe and a sealing mechanism. The valve protects the valve pipe through the antifreeze shell. The insulation plate on the inner wall of the antifreeze shell can ensure that the inner cavity of the antifreeze shell is in a warm state for a long time, further avoiding the phenomenon of ice and blockage of water placed inside the valve pipe during irrigation.

[0004] In the above patent, although the antifreeze shell, insulation board and heating wire are used to prevent ice and blockage inside the valve tube, the valve handle is easily frozen and rusted in rainy and snowy days during outdoor use, resulting in poor safety and durability. Secondly, the solar panel is horizontally arranged and exposed to the outside. After rainy and snowy weather, rain and snow are easily accumulated on the surface of the solar panel, which will affect the photoelectric conversion efficiency of the solar panel.

[0005] Therefore, a valve heating device with improved safety and durability is proposed to solve the above problems. Summary of the invention

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a valve heating device with improved safety and durability, and has the following beneficial effects:

[0020] 1. The present invention contracts the temperature-controlled thermistor spring so that the hot air flow inside the antifreeze pipe can flow to the top surface of the heat conduction groove, and transfer the heat to the photovoltaic panel, so that the photovoltaic panel can operate within a temperature range with relatively high electrical efficiency. When ice forms on the surface of the photovoltaic panel, the ice and snow can be melted into the contact layer with the photovoltaic panel, so that the ice and snow can easily slide down the inclined surface of the photovoltaic panel, and it is also convenient for rainwater to slide down. When the external environment becomes hot, the temperature-controlled thermistor spring expands and rebounds, so that the sleeve wraps the heat conduction port to block the heat flow, and avoid excessive heat from affecting the power generation efficiency of the photovoltaic panel. The valve pipe and the valve handle can be protected by the provision of a protective box and a protective cover to avoid freezing and rusting. The above structure can not only realize all-round protection of the valve pipe and the valve handle, but also automatically clean the snow on the surface of the photovoltaic panel, and avoid the influence of cold temperature on the photovoltaic panel, thereby improving the safety and durability of the device as a whole, improving the power generation efficiency of the photovoltaic panel after rainy and snowy weather, and ensuring that the valve can work normally during daily use.

[0021] 2. Through the setting of the balancing shell, the present invention can convert the gravitational potential energy into kinetic energy when the accumulated snow falls on the surface of the balancing shell, driving the protective box to deflect greatly. At this time, the springs on both sides of the slider are deformed. After the accumulated snow falls from the surface of the balancing shell, the spring drives the protective box to swing back and forth, causing the accumulated snow to slide off, thereby further improving the overall cleaning effect of the device on the snow on the surface of the photovoltaic panel.

[0022] 3. The present invention opens the protective box by pushing the protective cover. During this process, the round rod is compressed and the pull wire 2 is pulled by the fixed rod, so that the brush rod slides down along the slide rail through the track wheel. At the same time, the bristles clean the dust or snow and other obstructions on the surface of the photovoltaic panel. Moreover, the brush rod starts to pull and is pulled back to its original position. In the process of passing through the cleaning rod, the magnet 1 is alternately pushed by the magnets 2 on both sides, and combined with the elastic force of the spring 3, the bristles scrape the surface of the cleaning rod back and forth, thereby automatically cleaning the stains on the surface of the bristles, further improving the overall practicality of the device.

A heat conduction groove 311 is arranged inside the support seat 306, and two groups of heat conduction pipes 312 and two groups of sleeves 313 are arranged on the front and rear sides of the heat conduction groove 311. The two groups of heat conduction pipes 312 are respectively connected to the inlet and outlet of the heat conduction groove 311, and the two groups of sleeves 313 are installed on the top of the protective cover 302. The heat conduction pipes 312 are movably plugged into the sleeves 313. A heat conduction port 314 is provided at the bottom of the heat conduction pipe 312, and a group of circulation pipes 1 315 and a group of circulation pipes 2 316 are fixedly connected at the bottom of the two groups of sleeves 313, respectively. An antifreeze pipe 317 is fixedly sleeved at the middle of the valve pipe 1, and the antifreeze pipe 317 is located inside the protection box 301. The upper and lower sides of the antifreeze pipe 317 are respectively connected to the circulation pipes 1 315 and the circulation pipes 2 316, and the inner wall of the antifreeze pipe 317 is fixedly installed with a heating wire 318, and the heating wire 318 is electrically connected to the battery pack 310;

[0045] Specifically, the protection box 301 and the protection cover 302 are provided to protect the valve pipe 1 and the valve handle 2 from rust, thereby improving their safety and durability; the enclosure 307 is provided to prevent rain and snow from entering between the protection cover 302 and the support seat 306, thereby preventing ice from forming and affecting the normal operation of the internal structure of the enclosure 307; the temperature-controlled thermistor spring 308 is made of a thermosensitive material, and can shrink or expand with the outside temperature, thereby controlling whether the circulation pipe 1 315 is connected to the heat-conducting pipe 312; the battery pack 310 can be charged by an external power supply or by a solar panel, and the battery pack 310 provides electrical energy to generate heat from the heating wire 318, thereby keeping the internal environment of the antifreeze pipe 317 warm, thereby preventing ice from forming inside the valve pipe 1;

[0046] Among them, when the external environment of the protection box 301 and the protection cover 302 is cold, the temperature control thermistor spring 308 contracts, so that the heat pipe 312, the circulation pipe 1 315, the circulation pipe 2 316 and the antifreeze pipe 317 are connected, and the hot air flow inside the antifreeze pipe 317 can flow to the top surface of the heat conduction groove 311, and transfer the heat to the photovoltaic panel 309, so that the photovoltaic panel 309 can operate in a temperature range of 10°C to 30°C with higher power generation efficiency. When the surface of the photovoltaic panel 309 is frozen, the ice and snow can be melted and the contact layer with the photovoltaic panel 309 can be easily slid down along the inclined surface of the photovoltaic panel 309. When the external environment becomes hot, the temperature control thermistor spring 308 expands and rebounds, so that the sleeve 313 wraps the heat conduction port 314, blocks the heat flow, and prevents excessive heat from affecting the power generation efficiency of the photovoltaic panel 309.

[0047] Preferably, the bonding portion between the support seat 306 and the photovoltaic panel 309 is made of a heat-conducting material, and the top of the heat-conducting groove 311 is parallel to the top surface of the support seat 306;

[0048] Specifically, through this arrangement, heat can be transferred to the photovoltaic panel 309 more evenly.

[0049] Preferably, the diameters of the circulation pipe 1 315 and the circulation pipe 2 316 are both larger than the diameter of the heat conducting pipe 312, and the antifreeze pipe 317 is made of a heat-insulating material;

[0050] Specifically, the internal temperature of the antifreeze pipe 317 can be higher than the temperature between the insulation layer 303 and the antifreeze pipe 317, and the temperature between the insulation layer 303 and the antifreeze pipe 317 is higher than the external temperature of the protection box 301 in cold weather. The double-layer insulation improves the insulation effect and can concentrate the main heat in the antifreeze pipe 317, thereby reducing the power consumption of the heating wire 318.

[0051] Preferably, the elastic connecting member 304 comprises an inner ring plate 3041 fixedly mounted on the left and right sides of the protection box 301 and an outer ring plate 3042 fixedly sleeved on the left and right sides of the valve tube 1, the outer ring plate 3042 is rotatably connected to the outer surface of the inner ring plate 3041, a fan-shaped groove 3043 is provided on the inner side of the inner ring plate 3041, an arc rod 3044 is fixedly mounted in the fan-shaped groove 3043, a slider 3045 is fixedly mounted on the inner side of the outer ring plate 3042, the slider 3045 is slidably connected in the fan-shaped groove 3043 through the arc rod 3044, a spring 3046 is arranged between the front and rear sides of the slider 3045 and the inner ring plate 3041, the spring 3046 is sleeved on the outer surface of the arc rod 3044, and a balancing shell 319 is fixedly mounted on the bottom of the front and rear sides of the protection box 301;

[0052] Specifically, the fan-shaped groove 3043 can limit the shaking amplitude of the protection box 301 to avoid the situation where the protection box 301 shakes too much; when the snow on the surface of the photovoltaic panel 309 slides down, the accumulated snow falls on the surface of the balance shell 319, which can convert the gravitational potential energy into kinetic energy, drive the protection box 301 to deflect significantly, and shake the accumulated snow off the surface of the photovoltaic panel 309.

[0053] Preferably, the number of the springs 3046 is two, and the spring coefficient of the spring 3046 located on the front side of the slider 3045 is greater than that of the spring 3046 located on the rear side, so that the protective box 301 is easy to tilt toward the side where the height of the photovoltaic panel 309 is lower, and the elastic connecting member 304 is located below one-half of the height of the protective box 301, thereby increasing the instability of the protective box 301, so that when snow accumulates on the surface of the photovoltaic panel 309, the protective box 301 is easy to tilt, so that the snow on the top of the photovoltaic panel 309 can slide off and be removed.

[0054] Preferably, the second elastic connector 305 includes a sliding shell 3051 fixedly installed on the left and right sides of the top of the protective box 301, a round rod 3052 is fixedly installed inside the sliding shell 3051, and a second slider 3053 is fixedly installed on the left and right sides of the bottom of the protective cover 302, and the second slider 3053 is slidably connected to the sliding shell 3051 through the round rod 3052. The outer surface of the round rod 3052 is sleeved with a second spring 3054, and the second spring 3054 is arranged between the sliding shell 3051 and the second slider 3053. The sliding direction of the protective cover 302 is to slide in a horizontal direction along the photovoltaic panel 309 from high to low;

[0055] Specifically, when the protective cover 302 is slid open, snow and the like on the top surface of the photovoltaic panel 309 will fall out of the protective box 301, and the valve can be operated or repaired after the protective box 301 is opened.

[0056] For further example 2, please refer to Figures 8 to 12As shown:

[0057] It also includes a board cleaning component 4, which includes a cleaning frame 401 fixedly mounted on the top of the support seat 306, and slide rails 402 are provided on the left and right sides of the cleaning frame 401. A brush rod 403 is provided on the inner side of the top of the cleaning frame 401, and bristles 404 are provided on the bottom surface of the brush rod 403. The two ends of the brush rod 403 are slidably connected with an insertion rod 405, and a spring 406 is provided between the insertion rod 405 and the brush rod 403. The end of the insertion rod 405 away from the brush rod 403 is fixedly connected to a track wheel 407, and the insertion rod 405 is slidably connected to the slide rail 402 through the track wheel 407. A fixed block 408 is fixedly installed in the middle of the track wheel 407. A round shaft 409 is rotatably connected to the inner cavity of the top of the cleaning frame 401. A spring is arranged between the round shaft 409 and the cleaning frame 401, and the spring 410 is sleeved on the outer surface of the round shaft 409. Both ends of the round shaft 409 are wrapped around A pull wire 1 411 is arranged around, and one end of the pull wire 1 411 away from the circular shaft 409 is fixedly connected to the fixed block 408, and a pull wire 2 412 is also fixedly connected to the fixed block 408. The left and right sides of the bottom of the cleaning frame 401 are rotatably connected with pulleys 413, and fixed rods 414 are also fixedly installed on the left and right sides of the top of the protection box 301. One end of the pull wire 2 412 away from the fixed block 408 is fixedly installed on the end of the fixed rod 414 through the pulley 413. A plurality of cleaning rods 415 are fixedly installed on the inner side of the top of the cleaning frame 401, and the plurality of cleaning rods 415 are arranged in a row in the horizontal direction. Magnets 1 416 are fixedly installed on the tops of the two ends of the brush rod 403, and a plurality of magnets 2 417 are fixedly installed on the left and right sides of the top of the cleaning frame 401, and the plurality of magnets 2 417 on the left and right sides of the top of the cleaning frame 401 are staggered, and the magnets 1 416 and the magnets 2 417 repel each other.

[0058] Specifically, when the protective cover 302 slides open, the pull wire 412 is pulled, so that the bristles 404 clean the dust, snow and other obstructions on the surface of the photovoltaic panel 309; the brush rod 403 starts to pull and is pulled back to its original position. During the process of passing through the cleaning rod 415, the magnet 1 416 is alternately pushed by the magnets 417 on both sides, so that the bristles 404 scrape the surface of the cleaning rod 415, thereby automatically cleaning the stains on the surface of the bristles 404.

[0059] Preferably, the cleaning rack 401 is a U-shaped structure, and the opening is downward along the tilt direction of the photovoltaic panel 309;

[0060] Specifically, this arrangement facilitates the falling of large pieces of snow on the surface of the photovoltaic panel 309 .

[0061] Preferably, the surface of the cleaning rod 415 is configured to have a rough structure for cleaning the bristles 404 .

[0062] Everything in the above example works like this:

[0063] When the external environment of the protection box 301 and the protection cover 302 is cold, the temperature control thermistor spring 308 contracts due to the cold, driving the support seat 306 and the heat pipe 312 to descend. At this time, the heat conduction port 314 at the bottom of the heat pipe 312 is connected with the circulation pipe 1 315 and the circulation pipe 2 316, so that the heat conduction pipe 312, the circulation pipe 1 315, the circulation pipe 2 316 and the antifreeze pipe 317 are connected. Then, the hot air flow inside the antifreeze pipe 317 flows upward through the circulation pipe 1 315, and flows from one side of the heat conduction groove 311 to the other side of the heat conduction groove 311. It flows to the other side, and after cooling, the airflow passes through the circulation pipe 316 and enters the antifreeze pipe 317 over and over again, and transfers heat to the photovoltaic panel 309, so that when ice forms on the surface of the photovoltaic panel 309, the contact layer between the ice and snow and the photovoltaic panel 309 is melted, making it easy for the ice and snow to slide down the inclined surface of the photovoltaic panel 309. When the external environment becomes hot, the temperature-controlled thermistor spring 308 expands and rebounds, causing the sleeve 313 to wrap around the heat conduction port 314, blocking the circulation of hot air and preventing excessive heat from affecting the power generation efficiency of the photovoltaic panel 309.

[0064] When the snow on the surface of the photovoltaic panel 309 slides down, the accumulated snow falls on the surface of the balancing shell 319, which can convert the gravitational potential energy into kinetic energy, driving the protection box 301 to deflect greatly. At this time, the springs 1 3046 on both sides of the slider 1 3045 are deformed. After the accumulated snow falls from the surface of the balancing shell 319, the springs 1 3046 drive the protection box 301 to swing back and forth, thereby further sliding the accumulated snow off.

[0065] During each operation of the valve, the protective cover 302 is pushed to open the protective box 301. During this process, the round rod 3052 is compressed, and the pull wire 2 412 is pulled by the fixed rod 414, so that the brush rod 403 slides down along the slide rail 402 through the track wheel 407. At the same time, the bristles 404 clean the dust or snow on the surface of the photovoltaic panel 309. In addition, the pull wire 1 411 drives the round shaft 409 to rotate, so that the spring 410 is deformed. When the hand pushing the protective cover 302 is released, the round rod 3052 and the spring 410 rebound, driving the protective cover 302 and the brush rod 403 back to their original positions.

[0066] The brush rod 403 starts to be pulled and is pulled back to its original position. During the process of passing through the cleaning rod 415, the magnet 1 416 is alternately pushed by the magnet 2 417 on both sides, and with the elastic force of the spring 3 406, the bristles 404 reciprocate to scrape the surface of the cleaning rod 415, thereby automatically cleaning the stains on the surface of the bristles 404.
