Description

Technical Field

[0001] The present application relates to the technical field of snow removal in photovoltaic power stations, and specifically to a snow melting device for photovoltaic power stations. Background Art

[0002] Snow removal in photovoltaic power stations is an important operation and maintenance task, aiming to improve the power generation efficiency and safety of photovoltaic power stations.

[0003] In snow removal of photovoltaic power stations, manual snow removal is usually carried out using tools. Some larger power stations use inclined brackets to remove snow naturally by adjusting the angle. There are also heating devices installed on photovoltaic panels to remove snow by heating. However, manual snow removal wastes manpower and has low efficiency. Inclined snow removal depends on gravity and is not convenient for removing frozen snow blocks, resulting in poor snow removal effect. Installing heating devices on photovoltaic panels will complicate the structure of the photovoltaic panels themselves, and directly heating the photovoltaic panels easily leads to a decrease in the service life of the photovoltaic panels.

[0004] Therefore, the present application provides a reliable, effective snow removal and automated snow melting device for photovoltaic power stations to solve the above problems. Utility Model Content

[0005] The present application provides a snow melting device for photovoltaic power stations, aiming to solve the problems of waste of manpower, poor snow removal effect and poor stability in the existing snow removal of photovoltaic power stations as proposed in the background art.

[0006] To achieve the above object, the present application provides the following technical solution: A snow melting device for photovoltaic power stations includes a mounting frame for installing photovoltaic panels and a fixing frame fixed on the ground for supporting the mounting frame.

[0007] A plurality of mounting grooves are formed on the mounting frame in a linear array distribution, and a geothermal regulation mechanism is arranged in the mounting grooves.

[0008] The geothermal regulation mechanism includes a coil pipe fixedly installed in the mounting groove, a plurality of buried pipes embedded in the mounting frame for connecting the coil pipes in series to form a coil pipe group, a buried water tank buried underground, and a circulation pump connected to the outlet end of the coil pipe group through a return pipe. Among them, the outlet end of the circulation pump is connected to the buried water tank, and the inlet end of the coil pipe group is connected to the buried water tank through an upper water pipe. In this way, using geothermal energy, a renewable energy source, for heating not only reduces energy consumption compared with directly installing heating devices on photovoltaic panels, but also avoids the impact of heating on the life of photovoltaic panels. The entire snow melting process is automatically completed by mechanical devices without manual intervention, greatly improving work efficiency and reducing labor costs. The geothermal regulation mechanism can effectively increase the temperature of the environment around the photovoltaic panels, melt snow and ice, and improve the snow melting effect.

[0009] Preferably, a support frame for placing a photovoltaic panel is fixedly connected at a position corresponding to the upper side of the coil pipe in the installation groove, so as to fix the photovoltaic panel above the coil pipe through the support frame to provide stability.

[0010] Preferably, the outer wall of the coil pipe is provided with fins to improve the heat exchange efficiency of the coil pipe through the fins.

[0011] Preferably, the materials of the installation frame and the support frame are both aluminum. Aluminum has good thermal conductivity, and the heat exchange efficiency with the photovoltaic panel can be improved through the heat conduction of the structures of the installation frame and the support frame.

[0012] Preferably, both the coil pipe and the buried pipe are copper pipes. The coil pipe and the buried pipe are made of copper pipes, which have good thermal conductivity and are durable.

[0013] Preferably, the bottom surface of the installation frame is closed, and together with the photovoltaic panel, it can make the installation groove form a closed environment, thereby improving the heat exchange effect between the coil pipe group and the photovoltaic panel and achieving better heat preservation.

[0014] Preferably, a cleaning mechanism is arranged on the installation frame. The cleaning mechanism includes a gantry that moves horizontally on the installation frame, a lead screw that is rotatably installed on the side of the installation frame and is used to drive the gantry to move, and a motor that is fixedly installed on the side of the installation frame and whose output end is connected to the lead screw. Among them, a scraping strip is arranged on one side of the gantry close to the photovoltaic panel. When the water after snow melting or the remaining snow blocks need to be removed, the cleaning mechanism is started. The motor drives the lead screw to rotate, and then drives the gantry to move horizontally on the installation frame. The scraping strip on the gantry contacts the surface of the photovoltaic panel to scrape off the remaining water or snow blocks.

[0015] Preferably, the material of the scraping strip is rubber to reduce damage to the photovoltaic panel.

[0016] The snow melting device for the photovoltaic power station utilizes the renewable energy of geothermal energy for heating. Compared with directly installing a heating device on the photovoltaic panel, it not only reduces energy consumption but also avoids the influence of heating on the service life of the photovoltaic panel. The entire snow melting process is automatically completed by mechanical devices without manual intervention, greatly improving work efficiency and reducing labor costs. The geothermal regulation mechanism can effectively increase the temperature of the environment around the photovoltaic panel, melt snow and ice blocks, and improve the snow melting effect.

[0017] The snow melting device for the photovoltaic power station can not only melt snow on snowy days through the geothermal regulation mechanism, but also cool the photovoltaic panel on the ground through the temperature difference between the underground and the ground in a high-temperature environment, enabling the photovoltaic panel to generate electricity in a stable temperature environment, thereby ensuring the power generation efficiency of the photovoltaic panel.

[0018] The snow melting device for the photovoltaic power station, combined with the physical cleaning of the cleaning mechanism, avoids ice cubes hovering on the surface of the photovoltaic panel, ensuring the cleanliness of the photovoltaic panel surface and the power generation efficiency.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0028] Embodiment 1

[0029] This embodiment provides a snow melting device for a photovoltaic power station. As Figure 1 - Figure 2 shown, the snow melting device for the photovoltaic power station includes a mounting frame 1 for installing a photovoltaic panel and a fixing frame 2 fixed on the ground for supporting the mounting frame 1.

[0030] A plurality of mounting grooves 11 distributed in a linear array are formed on the mounting frame 1, and a geothermal regulation mechanism 3 is arranged in the mounting grooves 11;

[0031] The geothermal regulation mechanism 3 includes a coiled pipe 311 fixedly installed in the installation groove 11, a plurality of buried pipes 13 embedded in the installation frame 1 for connecting the coiled pipes 311 in series to form a coiled pipe group 31, a buried water tank 4 buried underground, and a circulation pump 34 connected to the outlet end of the coiled pipe group 31 through a return pipe 32. Among them, the outlet end of the circulation pump 34 is connected to the buried water tank 4, and the inlet end of the coiled pipe group 31 is connected to the buried water tank 4 through a water supply pipe 33.

[0032] During use, geothermal energy is stored in the buried water tank 4 and driven by the circulation pump 34. It enters the coiled pipe group 31 in the installation frame 1 through the water supply pipe 33. The coiled pipe group 31 is formed by connecting a plurality of coiled pipes 311 in series through the buried pipes 13 embedded in the installation frame 1. These coiled pipes 311 are distributed under the photovoltaic panels. The hot water heated by geothermal energy circulates in the coiled pipe group 31 and transfers heat to the air in the installation groove 11 or the bottom of the photovoltaic panel through heat conduction and convection, thereby increasing the temperature of the environment around the photovoltaic panel to achieve the purpose of snow melting. The heat-exchanged water then returns to the buried water tank 4 through the return pipe 32 to form a closed-loop cycle.

[0033] Furthermore, a support frame 12 for placing the photovoltaic panel is fixedly connected at a position corresponding to the upper part of the coiled pipe 311 in the installation groove 11. When installing the photovoltaic panel in the installation groove 11, through the support of the support frame 12, it is convenient for wire installation, ensuring that the photovoltaic panel is suspended above the coiled pipe 311, which is convenient for ensuring the heat exchange between the air around the photovoltaic panel and the coiled pipe 311.

[0034] Furthermore, the outer wall of the coiled pipe 311 has fins 312. When the circulating water passes through the coiled pipe 311, the fins 312 can better dissipate and absorb heat, which is beneficial to improving the heat exchange efficiency with the air around the photovoltaic panel.

[0035] Specifically, the materials of the installation frame 1 and the support frame 12 are both aluminum. Aluminum has good thermal conductivity, and the heat can be conducted through the structures of the installation frame 1 and the support frame 12 to improve the heat exchange efficiency with the photovoltaic panel. At the same time, the heat exchange efficiency between the installation frame 1 and the support frame 12 and the buried pipes 13 is also improved.

[0036] Among them, both the coiled pipe 311 and the buried pipe 13 are copper pipes, which have good thermal conductivity and are durable.

[0037] It should be noted that the bottom surface of the installation frame 1 is closed, and together with the photovoltaic panel, it can make the installation groove 11 form a closed environment, thereby improving the heat exchange effect between the coiled pipe group 31 and the air around the photovoltaic panel and achieving better heat preservation.

[0038] Embodiment 2

[0039] Different from Embodiment 1, after snow melting, water stains and broken ice will stay on the surface of the photovoltaic panel for a relatively long time before gradually sliding off or evaporating, shortening the lighting time of the photovoltaic panel and affecting the power generation efficiency. Therefore, as Figure 3 shown, a cleaning mechanism 5 is provided on the mounting frame 1. The cleaning mechanism 5 includes a gantry 51 that moves horizontally on the mounting frame 1, a lead screw 53 rotatably mounted on the side of the mounting frame 1 for driving the gantry 51 to move, and a motor 54 fixedly mounted on the side of the mounting frame 1 with its output end connected to the lead screw 53. Among them, a scraping strip 52 is provided on the side of the gantry 51 close to the photovoltaic panel, and the material of the scraping strip 52 is rubber.

[0040] After snow melting through the geothermal regulation mechanism 3, secondary treatment of the surface of the photovoltaic panel can be selected according to the actual situation. Specifically, the motor 54 drives the lead screw 53 to rotate, thereby driving the gantry 51 to move horizontally on the mounting frame 1. The scraping strip 52 on the gantry 51 contacts the surface of the photovoltaic panel, scraping off the remaining moisture or snow blocks, so that the photovoltaic panel is exposed to sunlight in the first time, ensuring the power generation efficiency. And the material of the scraping strip 52 is rubber, which can reduce the damage to the photovoltaic panel.

[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
