Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic, in particular to a photovoltaic module installation and positioning structure. Background Technique

[0002] Photovoltaic modules, also known as solar panels, are the core part of a solar power generation system. Their main function is to convert solar energy into electrical energy. The working principle of photovoltaic modules is based on the photovoltaic effect. That is, when photons irradiate semiconductor materials, the energy of the photons is absorbed, generating electron-hole pairs. These electrons and holes move towards the positive and negative electrodes respectively under the action of an electric field, forming an electric current. Photovoltaic modules mainly consist of solar cells, encapsulation films, photovoltaic glass, frames, junction boxes, etc., and are also divided into crystalline silicon modules and thin film modules according to different materials used.

[0003] When a photovoltaic module needs to be used, it needs to be fixedly installed on a corresponding photovoltaic module mounting bracket. Through this mounting bracket, not only can the photovoltaic module be carried and fixed, but also the position and angle of the module can be determined to ensure that they can effectively receive solar radiation and convert it into electrical energy. The design and installation of the photovoltaic bracket are crucial for the efficiency and stability of the entire solar power generation system. And such a photovoltaic module mounting bracket for fixing and positioning photovoltaic modules can be called a photovoltaic module installation and positioning structure.

[0004] However, if this photovoltaic module installation and positioning structure is used outdoors for a long time in areas with heavy industrial pollution, the air in the industrial area may contain acidic gases such as sulfides and nitrides. These pollutants will combine with water vapor to form acidic substances, thereby causing chemical corrosion to the photovoltaic module installation and positioning structure and affecting its service life. Therefore, it does not meet the existing requirements, and for this reason, we propose a photovoltaic module installation and positioning structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a photovoltaic module installation and positioning structure to solve the problems raised in the above background technique. That is, if this photovoltaic module installation and positioning structure is used outdoors for a long time in areas with heavy industrial pollution, the air in the industrial area may contain acidic gases such as sulfides and nitrides. These pollutants will combine with water vapor to form acidic substances, thereby causing chemical corrosion to the photovoltaic module installation and positioning structure and affecting its service life.

[0006] To achieve the above object, the utility model provides the following technical solution: A photovoltaic module installation and positioning structure, including a photovoltaic module installation and positioning frame. On one side of the photovoltaic module installation and positioning frame, there is a return frame. On one side inside the return frame, a stepping motor is fixedly installed.

At the lower end surface of the transmission rotating shaft, a lifting threaded rod is fixedly connected. On the lower side of the outer surface of the lifting threaded rod, an internal threaded sleeve matching its external thread is sleeved. On the outside of the internal threaded sleeve, an L-shaped plate is fixedly provided. On the surface of the L-shaped plate facing the photovoltaic module installation and positioning frame, a cleaning nozzle mounting plate is fixedly provided, and on the surface of the cleaning nozzle mounting plate facing the photovoltaic module installation and positioning frame, a plurality of flushing cleaning nozzles are installed.

On the surface of the base facing the return frame, a connecting rod is fixedly provided, and the other end of the connecting rod is fixed to the return frame.

[0008] Preferably, on both sides of the lifting threaded rod, a guide rod vertically passing through the L-shaped plate movably is provided, and the upper and lower end surfaces of the guide rod are fixed to the inner wall of the return frame.

[0009] Preferably, in front of the return frame, a water storage tank is provided. On one side of the outer surface of the water storage tank, a plurality of water delivery pipes with the same number and corresponding positions as the flushing cleaning nozzles are connected, and the other end of the water delivery pipe is connected to the corresponding flushing cleaning nozzle.

[0010] Preferably, on the other side of the outer surface of the water storage tank, a water replenishing pipe is connected, and the other end of the water replenishing pipe is connected to a faucet.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] The photovoltaic module installation positioning frame 1 (model D23), the flushing cleaning nozzle 5 (model CH22.50T), and the stepper motor 11 (model 2HSS5T-LC) mentioned in the present utility model can be obtained by purchasing from the market or customizing privately.

[0023] Please refer to Figures 1 to 4, an embodiment provided by the present utility model: a photovoltaic module installation and positioning structure, including a photovoltaic module installation and positioning frame 1. On one side of the photovoltaic module installation and positioning frame 1, there is a square frame 2. On one side inside the square frame 2, a stepping motor 11 is fixedly installed. The output shaft of the stepping motor 11 is connected to a transmission rotating shaft 12 through a coupling. At the lower end surface of the transmission rotating shaft 12, a lifting threaded rod 10 is fixedly connected. On the lower side of the outer surface of the lifting threaded rod 10, an internal thread sleeve 15 that matches its external thread is sleeved. On the outside of the internal thread sleeve 15, an L-shaped plate 4 is fixedly provided. On the surface of the L-shaped plate 4 facing the photovoltaic module installation and positioning frame 1, a cleaning nozzle mounting plate 13 is fixedly provided, and on the surface of the cleaning nozzle mounting plate 13 facing the photovoltaic module installation and positioning frame 1, a plurality of cleaning nozzles 5 for flushing are installed.

[0024] On both sides of the lifting threaded rod 10, a guide rod 7 vertically passing through the L-shaped plate 4 is provided, and the upper and lower end surfaces of the guide rod 7 are fixed to the inner wall of the square frame 2; through the guide rod 7 vertically passing through the L-shaped plate 4, the L-shaped plate 4 itself cannot rotate.

[0025] When the photovoltaic module installation and positioning frame 1 is used outdoors for a long time in an area with heavy industrial pollution, start the stepping motor 11 once a week. The stepping motor 11 can drive the lifting threaded rod 10 connected to it through the transmission rotating shaft 12 to rotate. Since the internal thread sleeve 15 sleeved on the lower side of the outer surface of the lifting threaded rod 10 is directly fixed to the L-shaped plate 4, the internal thread sleeve 15 cannot rotate. When the lifting threaded rod 10 connected to the internal thread sleeve 15 through a threaded structure rotates, under the transmission of the threaded structure, the internal thread sleeve 15 will move up and down accordingly. At this time, move the internal thread sleeve 15 upward. When the internal thread sleeve 15 moves upward, the L-shaped plate 4 fixed to it and the cleaning nozzle mounting plate 13 fixed to the outer surface of the L-shaped plate 4 will move upward together. As the cleaning nozzle mounting plate 13 rises, a plurality of cleaning nozzles 5 for flushing fixed to the outer surface of the cleaning nozzle mounting plate 13 will move upward synchronously. When the cleaning nozzles 5 for flushing move, water is sprayed through the cleaning nozzles 5 for flushing to wash away the chemical corrosive substances contaminated on the outer surface of the photovoltaic module installation and positioning frame 1. When the cleaning nozzles 5 for flushing can no longer move upward, drive the transmission rotating shaft 12 to rotate in the reverse direction through the stepping motor 11 to drive the cleaning nozzles 5 for flushing to move downward. After the cleaning nozzles 5 for flushing move up and down three times, turn off the stepping motor 11. Through the above technical solution, the photovoltaic module installation and positioning frame 1 can be prevented from being damaged by chemical corrosive substances, thereby increasing the service life of this photovoltaic module installation and positioning frame 1 in an area with heavy industrial pollution.

[0026] On both sides of the lower end surface of the photovoltaic module installation positioning frame 1, a base 14 is fixedly provided. On the surface of the base 14 facing the return-shaped frame 2, a connecting rod 3 is fixedly provided, and the other end of the connecting rod 3 is fixed to the return-shaped frame 2; a water tank support base is provided on the lower end surface of the water storage tank 8, and the surface of the water tank support base facing the return-shaped frame 2 is fixedly connected to the return-shaped frame 2 by bolts; the photovoltaic module installation positioning frame 1 and the return-shaped frame 2 are indirectly fixedly connected through the connecting rod 3, and the return-shaped frame 2 is directly fixedly connected to the water tank support base for supporting the water storage tank 8 by bolts. Through the rigid connection among the three, it can prevent the photovoltaic module installation positioning frame 1, the return-shaped frame 2, and the water storage tank 8 from moving, thereby causing misalignment of some structures of the entire device and ultimately affecting its use.

[0027] In front of the return-shaped frame 2, there is a water storage tank 8. On one side of the outer surface of the water storage tank 8, a plurality of water delivery pipes 6 with the same number and corresponding positions as the flushing nozzles 5 for flushing are connected, and the other ends of the water delivery pipes 6 are connected to the corresponding flushing nozzles 5; through the water storage tank 8 and the water delivery pipes 6, water sources can be provided for the operation of the flushing nozzles 5.

[0028] On the other side of the outer surface of the water storage tank 8, a water replenishing pipe 9 is connected, and the other end of the water replenishing pipe 9 is connected to a faucet; through the water replenishing pipe 9, water sources can be filled into the interior of the water storage tank 8.

[0029] Above the stepping motor 11, there is a circular cover plate on the outer surface of the return-shaped frame 2, and the return-shaped frame 2 and the circular cover plate are fixed by screws; through the circular cover plate, the stepping motor 11 can be protected, and when the stepping motor 11 fails, the circular cover plate can be removed for maintenance.

[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
