Description

Technical Field

[0001] This application relates to the technical field of new energy devices, and particularly to a device for cleaning ice and snow on the surface of photovoltaic modules based on high-pressure hot air sweeping. Background Art

[0002] Large-scale ground photovoltaic power stations cover a large area and are mostly built in places with harsh natural conditions such as deserts and gobi. When winter comes, these photovoltaic power stations are mostly covered with snow. After the wind and snow, due to the low temperature, the ice and snow accumulated on the photovoltaic modules are very difficult to melt. The presence of ice and snow will hinder sunlight irradiation and limit the temperature rise of the photovoltaic panels, thus reducing the power generation efficiency of the photovoltaic panels. In addition, the heavy pressure of ice and snow will accelerate the aging of the photovoltaic panels, which may cause cracks and damage. Therefore, it is particularly important to remove ice and snow from the surface of photovoltaic modules.

[0003] When cleaning the ice and snow on the surface of photovoltaic modules, soft items should be used, such as cleaning with a plastic shovel or a wooden shovel, and sharp tools should be avoided to prevent scratching or even breaking the tempered glass of the photovoltaic modules. Also, the photovoltaic modules cannot be directly flushed with hot water because uneven surface temperature may cause the glass layer to burst, resulting in faults and damage to the photovoltaic modules. Nor can people step on the photovoltaic modules for cleaning because photovoltaic modules have certain load-bearing requirements, and stepping on them may cause hidden cracks or damage to the modules, thus affecting the service life of the photovoltaic modules.

[0004] In the prior art, the measures to prevent ice and snow accumulation on the surface of photovoltaic modules mainly include the following points: (1) Inclined snow removal. Many solar panel manufacturers will tilt the solar panels at a certain angle or use a tracking bracket to tilt the photovoltaic panels so that the snow can slide off by itself. However, this method relies on the self-gravity of the ice and snow, and the effect of removing ice and snow is limited. (2) Electric heating devices or heating coils can help the photovoltaic panels remove snow. The heating device can form hot air around the photovoltaic panels, thereby accelerating the melting of the snow. However, the heating power of the heating device needs to be reasonably controlled to avoid causing the temperature of the photovoltaic panels to be too high and affecting their performance. (3) Self-cleaning nano film layer, which has super hydrophilicity and can make the snow melt and slide off more easily. However, the existence of this nano film layer will affect the power generation efficiency of the photovoltaic modules and increase the new energy utilization cost of the photovoltaic equipment. (4) Manual snow removal. In sunny weather, people can use professional snow removal tools to gently scrape off the snow safely. However, this method requires a large amount of manpower and material resources and has low efficiency. It can be seen that the existing methods for removing ice and snow from photovoltaic modules all have certain industrial application problems and cannot be widely used on a large scale.

[0034] At present, large-scale ground photovoltaic power stations are mostly built in places with relatively harsh natural conditions. In these areas, there is a lot of snow cover in winter and it is difficult to melt. The existence of ice and snow accumulation will reduce the power generation efficiency of photovoltaic panels, accelerate the aging of photovoltaic panels, and affect the service life of photovoltaic power stations. Therefore, it is particularly important to remove ice and snow from the surface of photovoltaic modules. In the prior art, common measures to prevent snow and ice accumulation on the surface of photovoltaic modules include inclined snow removal, electric heating snow removal, self-cleaning nanofilm snow removal, and manual snow removal, etc. However, the above methods for removing ice and snow from photovoltaic modules each have defects, there are certain industrial application problems, and they cannot be widely promoted and used on a large scale.

[0035] In order to solve the technical problems that the existing methods for removing ice and snow from photovoltaic modules have certain industrial application problems and cannot be widely promoted and used on a large scale, the present application provides a device for removing ice and snow from the surface of photovoltaic modules based on high-pressure hot air sweeping. Among them, the device removes ice and snow based on a high-pressure hot air system and a fully automatic crawler-type mobile sweeping robot, and the operation is more flexible and convenient, which can replace manual labor, making the investment in new energy utilization small and the effect good, and is conducive to the promotion and use by enterprises.

[0036] For the convenience of description in the following embodiments, a device 100 for removing ice and snow from the surface of photovoltaic modules based on high-pressure hot air sweeping according to an embodiment of the present application is taken as an example for description.

[0037] Please refer to Figure 1 , Figure 1 , a device 100 for removing ice and snow from the surface of photovoltaic modules based on high-pressure hot air sweeping provided by some embodiments of the present application, includes a photovoltaic power station 110, an energy storage system 120 connected to the photovoltaic power station 110. The device further includes a fully automatic crawler-type mobile sweeping robot 130 provided on the surface of the photovoltaic power station 110, a pipeline regulating device 140 connected to the energy storage system 120, a high-pressure hot air system 150, and a remote operation system 160 respectively connected to the high-pressure hot air system 150, the fully automatic crawler-type mobile sweeping robot 130, and the pipeline regulating device 140. The fully automatic crawler-type mobile sweeping robot 130 is provided with an air distributor 131 with adjustable angle and a self-driven sweeping brush 132. The air distributor 131 is connected to the high-pressure hot air system 150 to realize multi-angle cleaning of the ice and snow on the surface of the photovoltaic module.

[0038] The technical solution of the embodiment of the present application, compared with the traditional resistance heating and the angle adjustment of photovoltaic modules for ice and snow removal operations, uses the high-pressure hot air system 150 to make the ice and snow removal process faster and more thorough. And through the setting of the fully automatic crawler-type mobile sweeping robot 130, multi-angle cleaning and multi-stage cleaning of the ice and snow on the surface of the photovoltaic module can be realized, improving the treatment effect and efficiency of snow and ice accumulation on the surface of the photovoltaic module, and further avoiding the adverse effects of ice and snow on the power generation efficiency, structure and service life of the photovoltaic panel.

[0039] Further, in the embodiment of the present application, asFigure 3 As shown, the air distributor 131 is provided with multiple levels of air outlets 131-1 and bilateral angle adjustment shafts 131-2. The air outlet directions of the multiple levels of air outlets 131-1 are arranged facing the surface of the photovoltaic module, and the bilateral angle adjustment shafts 131-2 realize the relative angle adjustment between the multiple levels of air outlets 131-1 of the air distributor 131 and the surface of the photovoltaic module.

[0041] Furthermore, in the embodiment of the present application, as Figure 2 shown, the full-automatic crawler-type mobile cleaning robot 130 is further provided with a movable platform 133, a structural support body 134 fixed to the movable platform 133, a pipeline support and guiding roller 135 arranged on the structural support body 134, an upper arm 136 connecting the structural support body 134 and the air distributor 131, and a front arm 137 movably connecting the structural support body 134 and the self-driven cleaning brush 132.

[0042] In this embodiment, through the setting of the positions of the air distributor 131 and the self-driven cleaning brush 132, when the full-automatic crawler-type mobile cleaning robot 130 travels on the surface of the photovoltaic power station 110, the high-pressure hot air delivered by the air distributor 131 is first used to melt and blow off the ice and snow, and then the self-driven cleaning brush 132 is used for secondary cleaning to remove the ice and snow, realizing the deep cleaning of the surface of the photovoltaic module.

[0043] Furthermore, in some embodiments, the upper arm 136 is movably connected to the bilateral angle adjustment shafts 131-2 of the air distributor 131 to realize the multi-angle adjustment of the air distributor 131; the front arm 137 adjusts the relative height between the self-driven cleaning brush 132 and the surface of the photovoltaic module to realize the cleaning of the ice and snow on the surface of the photovoltaic module.

[0044] In this embodiment, the movable connection between the upper arm 136 and the bilateral angle adjustment shaft 131-2 drives the air distributor 131 to adjust the angle, so as to clean the ice and snow on the surface of the photovoltaic module from multiple angles by using the multi-stage air outlet 131-1; the front arm 137 adjusts the relative height between the self-driven cleaning brush 132 and the surface of the photovoltaic module, which can avoid damaging the surface of the photovoltaic module while cleaning the surface of the photovoltaic module.

[0045] Further, in some embodiments, please refer to Figure 1 As shown, the high-pressure hot air system 150 includes an air compressor air source 151, a pressure and air volume regulator 152, and a gas heater 153, and also includes a pipeline 154 that successively connects the air compressor air source 151, the pressure and air volume regulator 152, and the gas heater 153; the pipeline 154 successively passes through the pipeline adjustment device 140, the pipeline support and guide roller 135, and is connected to the air distributor 131 of the fully automatic tracked mobile cleaning robot 130. The air distributor 131 is also provided with an air distribution main pipe 131-3 and a quick air inlet 131-4 arranged above the air distribution main pipe 131-3. The multi-stage air outlet 131-1 is arranged below the air distribution main pipe 131-3, and the bilateral angle adjustment shaft 131-2 is arranged on both sides of the air distribution main pipe 131-3; the pipeline 154 is connected to the quick air inlet 131-4 of the air distributor 131.

[0046] In this embodiment, the gas provided by the air compressor air source 151 is regulated by the pressure and air volume regulator 152, then transported to the gas heater 153 through the pipeline 154 for heating, and then transported to the quick air inlet 131-4 of the air distributor 131, and output from the multi-stage air outlet 131-1 to the surface of the photovoltaic module, realizing the application of high-pressure hot air in cleaning the ice and snow on the surface of the photovoltaic module; and in this process, the pipeline 154 is adjusted by the pipeline adjustment device 140, mainly for the contraction adjustment of the pipeline 154 to make it suitable for the traveling speed of the fully automatic tracked mobile cleaning robot 130, and at the same time, the direction of the pipeline 154 is controlled by the pipeline support and guide roller 135.

[0047] Further, in some embodiments, the photovoltaic power station 110 includes a photovoltaic module 111, a photovoltaic support system 112, and an inverter 113 arranged on the photovoltaic support system 112. The inverter 113 connects the photovoltaic module 111 and the energy storage system 120, and the photovoltaic support system 112 is fixedly connected to the photovoltaic module 111 and the basic building. The inside of the movable platform 133 is provided with a driving battery 138, and the outer surface is provided with an anti-slip flexible track 139, and the anti-slip flexible track 139 is in contact with the surface of the photovoltaic module 111.

[0048] In this embodiment, the photovoltaic module 111 absorbs solar energy and converts it into electric energy, and supplies power to the energy storage system 120 through the inverter 113 for energy storage for subsequent use.

[0049] Further, in some embodiments, the energy storage system 120 is respectively connected to the pipeline regulating device 140, the air compressor air source 151 of the high-pressure hot air system 150, the air pressure and air volume regulator 152, and the gas heater 153, and the remote operation system 160 is respectively connected to the air compressor air source 151, the air pressure and air volume regulator 152, and the gas heater 153 of the high-pressure hot air system 150.

[0050] In this embodiment, the energy storage system 120 is connected to the pipeline regulating device 140, the air compressor air source 151 of the high-pressure hot air system 150, the air pressure and air volume regulator 152, and the gas heater 153 through cables and supplies power to them using the energy stored in itself; the remote operation system 160 maintains communication connections with the fully automatic tracked mobile cleaning robot 130, the pipeline regulating device 140, the air compressor air source 151 of the high-pressure hot air system 150, the air pressure and air volume regulator 152, and the gas heater 153 to realize the regulation and control of the output power of the air compressor air source 151, the output power of the gas heater 153, the output air pressure and air volume of the air pressure and air volume regulator 152, the rotation speed of the self-driven cleaning brush 132 of the fully automatic tracked mobile cleaning robot 130, and the rotation speed of the pipeline regulating device 140.

[0051] The working principle of the device 100 for cleaning ice and snow on the surface of photovoltaic modules based on high-pressure hot air is as follows:

[0052] Under sunny weather conditions, the photovoltaic modules 111 of the photovoltaic power station 110 absorb solar energy and convert it into electrical energy, which is supplied to the energy storage system 120 through the inverter 113 for energy storage. When snow and ice weather occurs, the remote operation system 160 is activated, and the working parameters are set: the output power of the air compressor air source 151, the output power of the gas heater 153, the output air pressure and volume of the air pressure and volume regulator 152, the rotation speed of the self-driven cleaning brush 132 of the fully automatic tracked mobile cleaning robot 130, and the rotation speed of the pipeline regulating device 140, etc. The energy storage system 120 starts to supply power to the air compressor air source 151, the gas heater 153, the air pressure and volume regulator 152, and the pipeline regulating device 140 respectively. The air compressor air source 151 starts to output compressed air. After being regulated by the air pressure and volume regulator 152 and heated by the gas heater 153, the compressed air is fed to the air distributor 131 of the fully automatic tracked mobile cleaning robot 130 through the pipeline 154 of the pipeline regulating device 140. The compressed air enters through the quick air inlet 131-4 and sprays out from the multi-stage air outlet 131-1 through the main air distribution pipe 131-3, realizing the rapid melting and blowing off of the snow and ice on the surface of the photovoltaic module 111 under the action of high-pressure hot air. During the gas blowing process, the fully automatic tracked mobile cleaning robot 130 is activated, and the fully automatic tracked mobile cleaning robot 130 is controlled to move on the surface of the photovoltaic module 111 through the remote operation system 160. The angle of the air distributor 131 is adjusted through the bilateral angle adjustment shaft 131-2. While the high-pressure hot air is blowing, the self-driven cleaning brush 132 is rotated, and the height of the self-driven cleaning brush 132 is adjusted through the front support arm 137 to realize the function of secondary deep cleaning and snow and ice removal. When the fully automatic tracked mobile cleaning robot 130 moves on the surface of the photovoltaic module 111, the pipeline regulating device 140 realizes the automatic retraction and extension of the pipeline 154 according to the distance of the travel. After the snow and ice removal operation is completed, the gas heater 153 and the fully automatic tracked mobile cleaning robot 130 are closed in sequence, then the air compressor air source 151 is closed, and finally the remote operation system 160 is closed.
