Description

Photovoltaic power generation system and its application

Technical Field

The present invention relates to the field of photovoltaic power generation, and in particular to a photovoltaic power generation system and applications thereof.

Background technique

Photovoltaic power generation system is a power generation system that uses solar cells to directly convert solar energy into electrical energy. Its characteristics are high reliability, long service life, no pollution to the environment, and the ability to generate electricity independently and connect to the grid. It is favored by all walks of life and has broad development prospects. Photovoltaic panels are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). They are an important part of the photovoltaic power generation system and will generate direct current when exposed to sunlight.

Most photovoltaic panel groups in the prior art are fixedly installed and directly exposed to the external environment. Dust and other impurities are easily deposited on the surface of the photovoltaic panel group after long-term operation. The dirt on the surface of the photovoltaic panel group affects the transmittance of light, thereby affecting the amount of radiation received by the surface of the component, thereby reducing the power generation efficiency of the photovoltaic component.

For example, the Chinese invention patent (application number: CN202310090710.7) discloses a “photovoltaic power generation component”, and its specification discloses: In a photovoltaic power generation component, a solar panel is a relatively core component, and its main function is to convert solar energy into electrical energy. In actual use, photovoltaic panels are usually exposed to the external environment. With continuous use, a layer of impurities will adhere to the surface of the photovoltaic panel, making it impossible for the semiconductor material on the surface of the photovoltaic panel to receive light well, which greatly reduces the power generation efficiency. The above patent can prove the defects of the existing technology.

Therefore, the protection module is set up to cover and protect the photovoltaic components, and the protection module is operated after the cleaning module is operated, ensuring the cleanliness of the photovoltaic components when they are used again.

Example 2

A photovoltaic power generation application, specifically, please refer to FIG. 2 to FIG. 4 , including a photovoltaic assembly, the photovoltaic assembly including a bracket 100, a support base 101 disposed on the top of the bracket 100, and a U-shaped frame 102 disposed in the middle of the support base 101;

The photovoltaic panel group 200 includes a pair of first photovoltaic panels 201 and a pair of second photovoltaic panels 202. The two first photovoltaic panels 201 are symmetrically installed on both sides of the upper surface of the support base 101, and the second photovoltaic panels 202 are symmetrically slidably inserted at both ends of the support base 101. By symmetrically distributing the two first photovoltaic panels 201 and the two second photovoltaic panels 202 on the support base 101, wherein the second photovoltaic panels 202 are slidably inserted, the second photovoltaic panels 202 can slide outward in the working state, so that the second photovoltaic panels 202 and the first photovoltaic panels 201 can be exposed to receive sunlight for converting electrical energy, and the space brought by the support base 101 is reasonably utilized. When the second photovoltaic panel 202 moves back to the inside of the support base 101, the second photovoltaic panel 202 is protected to ensure the working efficiency of the second photovoltaic panel 202.

The cleaning assembly 300 includes protective members 301 symmetrically arranged on both sides of the U-shaped frame 102, a connecting plate 302 is slidably arranged on the inner side of the U-shaped frame 102, a group of guide members 400 corresponding to the first photovoltaic panel 201 are arranged on both sides of the support seat 101, and a first cleaning member 303 is slidably arranged between the two opposite guide members 400, the two ends of the protective member 301 are respectively hinged to the corresponding connecting plate 302 and the first cleaning member 303, the protective member 301 is a plate-like structure, and the area of the protective member 301 is not less than the area of the first photovoltaic panel 201, when the connecting plate 302 slides downward along the U-shaped frame 102, the protective member 301 gradually covers the surface of the first photovoltaic panel 201, thereby protecting the first photovoltaic panel 201, and by cooperating with the above-mentioned support seat 101 to protect the second photovoltaic panel 202, it can play a protective role for the entire photovoltaic panel group 200, reducing the risk of impurities accumulating when the photovoltaic panel group is exposed to the external environment when it is not working.

The end of the support seat 101 is elastically provided with a second cleaning member 304. The first cleaning member 303 cleans the first photovoltaic panel 201 during the outward movement of the protective member 301, and simultaneously drives the second cleaning member 304 to contact the second photovoltaic panel 202. The first cleaning member 303 and the second cleaning member 304 are used to clean the dust and impurities on the surface of the first photovoltaic panel 201 and the second photovoltaic panel 202 to ensure their energy conversion efficiency.

The driving assembly 500 is arranged at the bottom of the bracket 100, and is used to drive the connecting plate 302 to slide downward along the U-shaped frame 102 and the second photovoltaic panel 202 to move back into the support seat 101. During the movement back of the second photovoltaic panel 202, it contacts the second cleaning member 304 to complete the cleaning of the second photovoltaic panel 202.

Example 3

A photovoltaic power generation application provided in Example 2 is further optimized. Specifically, please refer to Figures 2-8. A group of storage grooves 103 for plugging in the second photovoltaic panel 202 are symmetrically opened at both ends of the support base 101, and a group of linear slots 104 parallel to the sides of the support base 101 are symmetrically opened at the bottom of the support base 101. A connecting column 203 slidably connected to the linear slot 104 is set at the bottom end of the second photovoltaic panel 202.

Specifically, the driving assembly 500 includes a rotating member 501 arranged at the middle of the bottom end of the support seat 101, and the rotating member 501 is driven by a driving member 502 installed on the bracket 100 (the driving member 502 is a forward and reversible motor, which is connected to the control module, and the details are not repeated in this case), and a first piston member 503 is arranged between the rotating member 501 and the connecting column 203, and the end of the first piston member 503 is connected to the rotating member 501. Specifically, the first piston member 503 includes a first piston cylinder installed on the side of the rotating member 501, and the outer end of the first piston cylinder has a first piston rod, and the end of the first piston rod is provided with a connecting block, which is annular and movably sleeved on the connecting column 203. Then, when the rotating member 501 rotates to drive the entire first piston member 503 to rotate synchronously, since the linear slot 104 plays a guiding and limiting role, the connecting column 203 will drive the second photovoltaic panel 202 to move along the linear slot 104, and correspondingly, the medium in the first piston cylinder will be squeezed.

The top of the rotating member 501 is connected to the first pipe member 505 located on the top of the support seat 101 through a rotating connector 504, and the side of the first pipe member 505 is connected to a downward second piston member 506. In this case, the number of the second piston member 506 corresponds to the number of the first piston member 503, that is, two are also provided. The end of the second piston member 506 is connected to the connecting plate 302 through a connecting rod 507. The medium squeezed in the first piston cylinder enters the second piston member 506, thereby driving the connecting rod 507 and the connecting plate 302 to move downward (the connecting plate 302 has a second through groove 509 for the first pipe member 505 and the second piston member 506 to pass through, and the support seat 101 has a first through groove 508 for the piston rod of the second piston member 506 and the connecting rod 507 to press down), thereby controlling the corresponding work of the protective member 301, the first cleaning member 303 and the second cleaning member 304.

Example 4

Please refer to FIG. 2 to FIG. 11 , a photovoltaic power generation application, the first cleaning member 303 includes a connecting seat 3031 with an opening at the bottom, the bottom of the connecting seat 3031 is slidably provided with a first brush 3032, the guide member 400 has a circular guide groove 401, both ends of the bottom of the connecting seat 3031 are provided with a first movable notch 3033, the end of the first brush 3032 is provided with a guide rod 3034 that passes through the first movable notch 3033 and slides along the circular guide groove 401, the end of the circular guide groove 401 close to the outer end of the support seat 101 is embedded with a magnetic block 402, the end of the guide rod 3034 is provided with a guide block 3035 that repels the magnetic block 402, when the guide block 3035 slides along the bottom of the circular guide groove 401, the first brush 3032 cleans the first photovoltaic panel 201, correspondingly, when the guide block 3035 runs to the outer end of the circular guide groove 401, the thrust generated by the protective member 301 is greater than the magnetic block 4 02 has a repulsive force on the guide block 3035, so the guide block 3035 can move to the top of the magnetic block 402. At this time, the protective member 301 covers the surface of the first photovoltaic panel 201, and the first photovoltaic panel 201 moves back to the storage groove 103. The thrust of the guide block 3035 by the protective member 301 disappears, and the repulsive force pushes the guide block 3035 upward, and the guide block 3035 moves to the groove above the circular guide groove 401. When the protective member 301 covers the first photovoltaic panel 201 and protects it, the first plate brush 3032 has completed a cleaning of the first photovoltaic panel 201. Therefore, when the protective member 301 moves up with the connecting plate 302, the guide block 3035 moves along the groove above the circular guide groove 401, so that the first plate brush 3032 is separated from the first photovoltaic panel 201 during the exposure of the first photovoltaic panel 201, which reduces the frequency of friction use of the first plate brush 3032 and increases the service life of the first plate brush 3032.

Correspondingly, the second cleaning member 304 includes a second brush 3041 movably arranged at the notch of the receiving groove 103, a groove 3042 parallel to the guide member 400 is provided on the support seat 101, a second movable groove 3043 is provided between the end of the groove 3042 and the notch of the receiving groove 103, a lower pressure plate 3044 is elastically provided in the groove 3042, and the end of the second brush 3041 has a convex column 3045 passing through the second movable groove 3043 and connected to the lower pressure plate 3044, a lower pressure block 3046 corresponding to the lower pressure plate 3044 is provided on the guide rod 3034, and the lower pressure block 3046 and the opposite ends of the lower pressure plate 3044 are both provided with an arc, and the first brush 3032 is moved along the bottom of the circular guide groove 401 During sliding, the lower pressure plate 3044 is squeezed and the second brush 3041 is driven to contact the surface of the second photovoltaic panel 202. That is, while the protective member 301 is protecting the first photovoltaic panel 201 and the first cleaning member 303 is cleaning the first photovoltaic panel 201, the second photovoltaic panel 202 is driven by the driving member 502 to move into the storage groove 103, contact the second brush 3041, and push out dust and other impurities on its surface, thereby completing the cleaning of the second photovoltaic panel 202. Correspondingly, when the second photovoltaic panel 202 moves outward, the first brush 3032 is separated from the first photovoltaic panel 201, so that the lower pressure plate 3044 is elastically reset, and the second brush 3041 is separated from the second photovoltaic panel 202, thereby increasing the service life of the second brush 3041.

When the bracket 100 is installed, the U-shaped frame 102 is vertically facing the end where the sun rises. Therefore, when the sun shines on the photovoltaic component, the U-shaped frame 102 and the protective member 301 and other structures produce a shadow at the corresponding rear end, thereby improving the conversion efficiency of the first photovoltaic panel 201.

The use process of the photovoltaic power generation application provided by the present invention is as follows:

When the bracket 100 is installed, the U-shaped frame 102 is vertically facing the end where the sun rises;

At night or before snow and wind, the control module controls the driving member 502 to drive the rotating member 501 to rotate. The rotation of the rotating member 501 drives the entire first piston member 503 to rotate synchronously. Since the linear notch 104 plays a guiding and limiting role, the connecting column 203 moves along the linear notch 104 driven by the rotation of the first piston member 503. Correspondingly, the connecting column 203 squeezes the first piston member 503, and the first piston member 503 enters the second piston member 506, and then drives the connecting plate 302 to move downward through the connecting rod 507, that is, the second photovoltaic panel 202 moves synchronously with the protective member 301. When the protective member 301 completely covers the first photovoltaic panel 201, the second photovoltaic panel 202 synchronously and completely enters the storage groove 103. As shown in Figure 11, during the movement of the protective member 301, the first cleaning member 303 is pushed to move along the surface of the first photovoltaic panel 201 to clean the first photovoltaic panel 201. At the same time, the lower pressing block 3046 squeezes the lower pressing plate 3044, so that The second cleaning member 304 moves downward, that is, the second photovoltaic panel 202 moving into the storage groove 103 is cleaned synchronously. After the protective member 301 completely covers the first photovoltaic panel 201, the thrust of the protective member 301 on the guide block 3035 disappears, and then the repulsive force of the magnetic block 402 on the guide block 3035 pushes the guide block 3035 to move upward. That is, during the resetting process of the protective member 301, the first photovoltaic panel 201 and the second photovoltaic panel 202 have been cleaned, and the first photovoltaic panel 2 01 and the second photovoltaic panel 202 are protected by the protective member 301 and the storage groove 103, which reduces the accumulation of impurities. Therefore, the guide block 3035 moves along the groove above the circular guide groove 401, and the first brush 3032 is separated from the first photovoltaic panel 201. Correspondingly, the squeezing of the elastically arranged lower pressure plate 3044 disappears synchronously, and the second brush 3041 is separated from the second photovoltaic panel 202, thereby reducing the use frequency of the first brush 3032 and the second brush 3041 and increasing their service life.
