Description

Technical Field

[0001] This utility model relates to the field of photovoltaic air-supported membrane structure technology, specifically to an energy system for a photovoltaic air-supported membrane structure. Background Technology

[0002] An air-supported membrane structure is an inflatable building structure made of special architectural membrane material and formed by air pressurization technology. It has a large span, can be constructed quickly, and can be disassembled, relocated, and reinstalled as needed. It is highly flexible and suitable for temporary sites or projects that require frequent relocation. A photovoltaic air-supported membrane structure is a new type of structure that combines air-supported membrane technology and photovoltaic technology. It generates solar power by installing photovoltaic modules on the top or walls of the air-supported membrane structure to save energy consumption during use. However, during use, dust and other debris will gradually accumulate on the outer surface of the photovoltaic modules, which will seriously affect the power generation of the photovoltaic system and lead to increased electricity costs. Utility Model Content

[0003] The purpose of this invention is to provide an energy system for a photovoltaic air-supported membrane structure, in order to solve the problem mentioned in the background art that photovoltaic modules tend to accumulate dust and debris over a long period of use, resulting in a decrease in power generation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an energy system for a photovoltaic air-supported membrane structure, comprising a mounting frame, the mounting frame being fixedly installed on a foundation wall, and an air-supported membrane being fixedly installed at one end of the mounting frame away from the foundation wall; an mounting corner being fixedly installed on the side surface of the mounting frame, and an arc-shaped bracket being fixedly installed on the outer surface of the mounting corner, wherein the outer surface of the arc-shaped bracket does not contact the outer surface of the air-supported membrane; a flexible solar panel is arranged between the arc-shaped brackets, and the flexible solar panel is divided into two parts based on the apex of the air-supported membrane; a spray filtration mechanism is arranged between the mounting frame and the arc-shaped brackets, and the outer surface of the flexible solar panel is rinsed through the spray filtration mechanism to keep the outer surface of the flexible solar panel clean.

[0005] Preferably, the spray filtration mechanism includes: a water collection tank, which is fixedly installed between arc-shaped supports, and the arc-shaped supports and the water collection tank are fixed to each other. The interior of the water collection tank is inclined, and a water collection pump is fixedly installed on the outer surface of the water collection tank and connected to the water collection tank. A spray washing frame is fixedly installed at the end of the arc-shaped supports away from the mounting frame, and the outer surface of the spray washing frame is provided with nozzles. The nozzles of the spray washing frame face both sides of the flexible solar panel. The spray washing frame is connected to the output end of the water collection pump.

[0006] By adopting the above technical solution, water can be pumped out of the water collection tank by the water collection pump and sent into the spray washing frame. Then, water can be sprayed onto the flexible solar panel through the spray holes set on the outer surface of the spray washing frame. The water washes away the dust and debris on the outer surface of the flexible solar panel, ensuring the power generation capacity of the flexible solar panel.

[0007] Preferably, a filter screen groove is fitted inside the water collection tank, and the outer surface of the filter screen groove is in contact with the outer surface of the water collection tank, with the flexible solar panel located above the filter screen groove.

[0008] By adopting the above technical solution, the dirt and dust washed off can be easily filtered, allowing the water to be reused and improving water utilization. At the same time, the dirt and dust can be collected in the filter screen groove for easy cleaning.

[0009] Preferably, a connecting support rod is installed through the arc-shaped brackets, and a nut is threaded on the outer surface of the connecting support rod. The nut on the outer surface of the connecting support rod fits into the outer surface of the arc-shaped bracket, and a flexible solar panel is fixedly installed on the outer surface of the connecting support rod.

[0010] By adopting the above technical solution, the connecting support rods can provide auxiliary support and fixation between the arc-shaped supports, while also providing support for the flexible solar panels and leaving a gap between the flexible solar panels and the air film, thereby reducing the temperature rise caused by direct sunlight on the air film.

[0011] Preferably, a movable frame is provided between the arc-shaped supports, and the outer surface of the movable frame is in contact with the outer surface of the arc-shaped supports. Guide rollers are fixedly installed on the outer surfaces of both ends of the movable frame, and the guide rollers are engaged with the arc-shaped supports. An output motor is fixedly installed on the outer surface of the movable frame, and the output end of the output motor passes through the outer surfaces of both ends of the movable frame.

[0012] By adopting the above technical solution, the movable frame can be fixedly engaged on the outer surface of the arc-shaped bracket, so that the movable frame can move upward on the arc-shaped bracket through the guide fixed rollers without falling off.

[0013] Preferably, a rotating engagement mechanism is provided between the arc-shaped support, the movable frame and the output motor, and the rotating engagement mechanism is used to clean stubborn stains on the outer surface of the flexible solar panel.

[0014] By using the above technical solution, stubborn stains adhering to the outer surface of the flexible solar panel can be removed by brushing rollers, ensuring the smoothness of the outer surface of the flexible solar panel and keeping the flexible solar panel clean without any residue.

[0015] Preferably, the rotating engagement mechanism includes: a strip ruler, which is fixed to the outer surface of the arc-shaped bracket, and the arc-shaped bracket and the strip ruler are concentrically designed; a first gear is fixedly installed at both ends of the output motor, and the first gear meshes with the strip ruler; a brush roller is rotatably installed on the outer surface of the movable frame, and both ends of the brush roller penetrate the outer surface of the movable frame; a second gear is fixedly installed at both ends of the brush roller, and the second gear is located on both sides outside the movable frame; a groove is formed on the side of the arc-shaped bracket near the flexible solar panel, and the groove engages with the second gear, and the diameter of the second gear is smaller than the diameter of the groove; the outer surface of the brush roller is in contact with the outer surface of the flexible solar panel.

[0016] Using the above technical solution, the output motor rotates to drive the first gear to rotate, so that the first gear meshes with the strip ruler, driving the moving frame to move on the arc-shaped support. At the same time as the arc-shaped support moves, the second gear meshes with the groove strip and drives the second gear to rotate. The rotation of the second gear causes the brushing roller to rotate along with the moving frame. The diameter difference between the groove strip and the second gear enables the brushing roller to accelerate the brushing of the outer surface of the flexible solar panel, so that the flexible solar panel can be brushed cleaner.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the energy system of the photovoltaic air-supported membrane structure:

[0018] 1. After prolonged use, the water collection pump needs to be activated to extract water from the water collection tank. The extracted water then enters the spray washing frame and is sprayed out, allowing the water to flow down from the highest point of the air film chamber. This washes away dust and dirt from the outer surface of the flexible solar panel, and the water returns to the water collection tank. The impurities and dust in the water will be filtered by the filter screen, preventing them from entering the water collection pump and spray washing frame and causing blockages or wear on parts. This also allows for the collection of dust and debris for easy cleaning, keeping the outer surface of the flexible solar panel clean and ensuring that the flexible solar panel maintains its optimal state when generating electricity.

[0019] 2. The air-supported membrane structure can be easily assembled and installed by splicing together mounting frames, mounting corners, arc-shaped brackets, and connecting support rods. The connecting support rods can strengthen the connection stability between arc-shaped brackets, making the arc-shaped brackets less prone to deformation and movement. Flexible solar panels can also be installed and supported through the connecting support rods, which facilitates the installation of flexible solar panels and provides stable support to reduce the chance of damage. The gap between the flexible solar panel and the air-supported membrane prevents direct sunlight from hitting the air-supported membrane, reducing the heat radiation received by the air-supported membrane. The gap between the flexible solar panel and the air-supported membrane allows air circulation, improving the stability of the installation and support of the flexible solar panel and reducing the temperature rise caused by heat radiation to the air-supported membrane.

[0020] 3. The rotation of the output motor drives the first gear to rotate, and when the first gear meshes with the bar ruler, it drives the moving frame to move. The moving frame can move along the outer surface of the arc-shaped support. The engagement of the guide fixing roller with the arc-shaped support prevents the moving frame from falling off the arc-shaped support during movement. Furthermore, the engagement of the second gear with the grooved strip allows the brushing roller to rotate along with the moving frame during movement. Together with the sprayed water, this can better clean stubborn stains on the outer surface of the flexible solar panel. As the moving frame moves, the brushing roller can rotate and scrub, making the flexible solar panel cleaner. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: an energy system for a photovoltaic air-supported membrane structure, including a mounting frame 1, which is fixedly installed on a foundation wall. An air-supported membrane is fixedly installed at one end of the mounting frame 1 away from the foundation wall. An mounting corner 2 is fixedly installed on the side surface of the mounting frame 1, and an arc-shaped support 3 is fixedly installed on the outer surface of the mounting corner 2. The outer surface of the arc-shaped support 3 does not contact the outer surface of the air-supported membrane. A flexible solar panel 5 is arranged between the arc-shaped supports 3, and the flexible solar panel 5 is divided into two parts based on the apex of the air-supported membrane. A spray filtration mechanism is arranged between the mounting frame 1 and the arc-shaped support 3 to rinse the outer surface of the flexible solar panel 5, keeping the outer surface of the flexible solar panel 5 clean.

[0030] When assembling the energy system of the photovoltaic air-supported membrane structure, the mounting frame 1 needs to be fixed to the wall base where it needs to be installed first. Then, the mounting corner 2 is fixed to the side surface of the mounting frame 1. After finding the horizontal position, the arc-shaped bracket 3 is fixed on the mounting corner 2, and the connecting support rod 4 is assembled and connected to the arc-shaped bracket 3. After the photovoltaic energy system is installed, the air model is installed on the outer surface of the mounting frame 1 and inflated to complete the assembly of the photovoltaic air-supported membrane structure.

[0031] The spray filtration mechanism includes: a water collection tank 7, which is fixedly installed between arc-shaped supports 3, and the arc-shaped supports 3 and the water collection tank 7 are fixed to each other. The interior of the water collection tank 7 is inclined, and a water collection pump 9 is fixedly installed on the outer surface of the water collection tank 7 and connected to the water collection tank 7. A spray washing frame 10 is fixedly installed at the end of the arc-shaped supports 3 away from the mounting frame 1, and the outer surface of the spray washing frame 10 is provided with nozzles. The nozzles of the spray washing frame 10 face the two sides of the flexible solar panel 5 respectively, and the spray washing frame 10 is connected to the output end of the water collection pump 9.

[0032] With prolonged use, debris and dust will inevitably accumulate on the outer surface of the flexible solar panel 5. At this time, the water collection pump 9 can be started first to draw water stored in the water collection tank 7 and send it into the spray washing frame 10. This allows the water to fall freely from the top of the air film chamber to wash the outer surface of the flexible solar panel 5, washing away the dust and dirt and keeping the outer surface of the flexible solar panel 5 clean. This eliminates the need to climb up and down to clean the flexible solar panel 5, improving cleaning efficiency and reducing the difficulty and danger of cleaning, so that the flexible solar panel 5 can maintain optimal power generation.

[0033] The water collection tank 7 has a filter screen groove 8 installed inside, and the outer surface of the filter screen groove 8 is in contact with the outer surface of the water collection tank 7. The flexible solar panel 5 is located above the filter screen groove 8.

[0034] As the water sprayed down from the washing rack 10 carries dust and dirt, it is intercepted by the filter screen 8, preventing debris from entering the water collection tank 7. This reduces blockages and damage caused by debris entering the pipes, improves water utilization, and facilitates cleaning.

[0035] A connecting support rod 4 is installed through the arc-shaped brackets 3, and a nut is threaded on the outer surface of the connecting support rod 4. The nut on the outer surface of the connecting support rod 4 fits against the outer surface of the arc-shaped brackets 3. A flexible solar panel 5 is fixedly installed on the outer surface of the connecting support rod 4.

[0036] The connecting support rod 4 and the nut can be used to fix and reinforce the arc bracket 3, reducing the chance of deformation and damage to the arc bracket 3. The connecting support rod 4 can also be used to fix the flexible solar panel 5 and provide support for the flexible solar panel 5, and leave a gap between the flexible solar panel 5 and the air film to reduce the temperature rise caused by direct sunlight on the air film.

[0037] A movable frame 11 is provided between the arc-shaped brackets 3, and the outer surface of the movable frame 11 is in contact with the outer surface of the arc-shaped brackets 3. Guide and fixing rollers 14 are fixedly installed on the outer surfaces of both ends of the movable frame 11, and the guide and fixing rollers 14 are engaged with the arc-shaped brackets 3. An output motor 12 is fixedly installed on the outer surface of the movable frame 11, and the output end of the output motor 12 passes through the outer surfaces of both ends of the movable frame 11.

[0038] By engaging the guide roller 14 with the arc-shaped bracket 3, the movable frame 11 can move on the arc-shaped bracket 3 in a fixed direction, and the movable frame 11 will not fall off the arc-shaped bracket 3 when it moves.

[0039] A rotating engagement mechanism is provided between the arc-shaped bracket 3, the movable frame 11, and the output motor 12. The rotating engagement mechanism cleans stubborn stains on the outer surface of the flexible solar panel 5. The rotating engagement mechanism includes: a strip ruler 6, which is fixed on the outer surface of the arc-shaped bracket 3 and the arc-shaped bracket 3 and the strip ruler 6 are concentrically designed; a first gear 13 is fixedly installed at both ends of the output motor 12 and meshes with the strip ruler 6; a brush roller 16 is rotatably installed on the outer surface of the movable frame 11 and its two ends penetrate the outer surface of the movable frame 11; a second gear 15 is fixedly installed at both ends of the brush roller 16 and is located on both sides outside the movable frame 11; a groove strip 17 is provided on the side of the arc-shaped bracket 3 near the flexible solar panel 5 and engages with the second gear 15; the diameter of the second gear 15 is smaller than the diameter of the groove strip 17; and the outer surface of the brush roller 16 is in contact with the outer surface of the flexible solar panel 5.

[0040] As the output motor 12 rotates, it drives the first gear 13 to rotate as well. Through the meshing of the first gear 13 with the strip ruler 6, the moving frame 11 can move on the arc support 3 when the output motor 12 starts. As the moving frame 11 moves, the groove strip 17 will cause the second gear 15 to rotate, driving the brushing roller 16 to rotate. This allows the brushing roller 16 to clean and brush the outer surface of the flexible solar panel 5, removing stubborn stains from the outer surface of the flexible solar panel 5 and preventing stubborn stains from remaining on the outer surface of the flexible solar panel 5. The diameter difference between the second gear 15 and the groove strip 17 allows the brushing roller 16 to rotate faster. Combined with the water sprayed by the spray frame 10, the flexible solar panel 5 can be brushed cleaner.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
