[0002] Photovoltaic panels are a type of power generation device that is different from other common forms of power generation. They do not require rotating equipment such as prime movers and generators, but directly convert sunlight into electrical energy. They have high economic value and are often installed in wider areas.

[0003] As the application of photovoltaic panels becomes more widespread, and some residents also install photovoltaic panels outdoors, water is easily gathered on the photovoltaic surface in rainy weather. The water seeps into the photovoltaic mounting base from the edge of the photovoltaic panel, causing the sealing of the photovoltaic mounting base to decrease and causing the bottom of the photovoltaic panel to be in a wet state for a long time, affecting the service life of the photovoltaic panel. At the same time, the flow of water causes dust to adhere to the surface of the photovoltaic panel, reducing the working efficiency of the photovoltaic panel. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 6 The present invention provides a technical solution: a photovoltaic panel assembly that is easy to drain, comprising:

[0030] A photovoltaic panel assembly for facilitating drainage, comprising:

[0031] A base 1, wherein a receiving groove 2 is formed on the base 1, and a plurality of drainage holes 19 are evenly formed on the receiving groove 2;

[0032] The clamping assembly is arranged in the receiving groove 2. The clamping assembly is provided in multiple groups. When the clamping assemblies rotate to approach each other and abut against each other, the photovoltaic panel is clamped.

[0033] When the photovoltaic panel 20 is not installed, the clamping assembly is stored in the storage groove 2. When the photovoltaic panel 20 needs to be installed, the clamping assembly is rotated to make them approach and abut against each other, and then cooperate to form a supporting shape and a supporting space to support and clamp the photovoltaic panel 20. Since multiple groups of clamping assemblies cooperate to install the photovoltaic panel 20 and the clamping assembly can rotate, the air in the supporting space formed at the bottom end of the photovoltaic panel 20 can circulate. Therefore, in rainy and snowy weather, the bottom end of the photovoltaic panel 20 can be prevented from being in a wet state for a long time.

[0034] In this embodiment, the clamping assembly includes a slider 10. A plurality of sliding grooves 3 are formed in the storage groove 2, and the sliding grooves 3 are radially distributed along the center of the storage groove 2. The sliders and the sliding grooves 3 are in one-to-one correspondence. A clamping wing 4 is rotatably connected to the slider 10, and the clamping wings 4 are connected and locked by a pin 11.

[0035] By sliding some of the sliders 10 away from the center of the storage groove 2 and simultaneously rotating the corresponding clamping wings 4 in the vertical direction, the clamping wings 4 are rotated and approached to each other, and the clamping wings 4 are connected and locked by the pin 11. At this time, this part of the clamping wings 4 forms a semi-enclosed structure. As Figure 2 shown, it is provided with four clamping wings 4. At this time, any three sliders 10 can be slid, the corresponding clamping wings 4 are rotated and fixed by the pin 11. At this time, a semi-enclosed structure in the shape of "匚" is formed between the clamping wings 4.

[0036] In this embodiment, a positioning assembly is provided on any two opposite clamping wings 4, and the positioning assembly is used for the preliminary positioning of the photovoltaic panel.

[0037] In this embodiment, the positioning assembly includes a mounting block 5, a linkage member one 6 and a linkage member two 7. The mounting block 5 is fixedly connected to the clamping wing 4. An installation cavity is formed in the mounting block 5. The linkage member one 6 is slidably connected to the mounting block 5 in the vertical direction. The bottom end of the linkage member one 6 is inserted into the installation cavity. A first rack 16 is connected to the bottom end of the linkage member one 6. A gear 9 is rotatably connected in the installation cavity. The gear 9 meshes with the first rack 16. The linkage member two 7 has an "L" - shaped structure. A second rack 8 is connected to the horizontal section of the linkage member two 7. The second rack 8 meshes with the gear 9. A contact plate 17 is provided on the linkage member two 7.

[0038] The photovoltaic panel 20 is placed on the structure formed by the clamping wings 4 in a semi-enclosed shape. At this time, the gravity of the photovoltaic panel 20 exerts a certain pressure on the linkage member 6, thereby driving the linkage member 6 to slide downward. At this time, the first rack 16 drives the gear 9 to rotate, thereby driving the linkage member 2 7 and the second rack 8 to slide horizontally, so that the abutment plate 17 abuts and clamps the two sides of the photovoltaic panel 20, thereby completing the preliminary positioning of the photovoltaic panel 20, and then the remaining clamping wings 4 are rotated to connect and position, thereby forming a fully enclosed clamping and positioning for the photovoltaic panel 20.

[0039] In this embodiment, a dovetail groove is provided on the horizontal section of the linkage member 2 7 , and a dovetail tenon is installed at the bottom of the abutment plate 17 , and the dovetail tenon is inserted in the dovetail groove.

[0040] The sliding direction of the abutment plate 17 is limited by the setting of the dovetail tenon, and due to the contraction shape of the dovetail groove opening, the possibility of the abutment plate 17 being separated from the linkage member 7 during the sliding process is reduced to a certain extent.

[0041] In this embodiment, a spring and a telescopic rod 18 are connected between the vertical section of the second linkage member 7 and the abutment plate 17 , and the spring is disposed inside the telescopic rod 18 .

[0042] The spring is arranged in the telescopic rod 18. To a certain extent, the telescopic rod 18 not only guides the movement of the abutment plate 17, but also wraps the spring, thus playing a certain protective role.

[0043] In this embodiment, a wiper assembly is provided on any of the clamping wings 4 , and the wiper assembly is used to move along the surface of the photovoltaic panel 20 to wipe the water.

[0044] In this embodiment, the wiper assembly includes a mounting plate 12, a scraper 13 and a connecting belt 14. The scraper 13 is fixedly connected to the bottom end of the mounting plate 12. One end of the connecting belt 14 is fixedly connected to the mounting plate 12. The other end of the connecting belt 14 is wrapped with a connecting rod. The connecting rod is rotatably set in the clamping wing 4. A torsion spring is also set between the clamping wing 4 and the connecting rod.

[0045] By pulling the scraper 13, the connecting rod rotates to release the connecting belt 14, so that the scraper 13 can move along the photovoltaic panel 20, that is, to scrape off the water stains remaining on the photovoltaic panel 20. After scraping, the scraper 13 is released, and the connecting rod rotates under the reset action of the torsion spring, driving the scraper 13 back to its original position.

[0046] In this embodiment, a water diversion groove 21 is provided on the parallel clamping wings 4 of the wiper assembly. The bottom surface of the water diversion groove 21 is inclined, and the lower side of the water diversion groove 21 is connected to the drain pipe 15.

[0047] The water stains on the photovoltaic panel 20 are drained by the arrangement of the water diversion trough 21 and the drainage pipe 15 .

[0048] In this embodiment, a torsion elastic member is disposed between the slider 10 and the clamping wing 4 , and the torsion elastic member is used to drive the clamping wing 4 to move toward the base 1 .

[0049] The torsional elastic member can be a tension spring. Through the setting of the tension spring, when the photovoltaic panel 20 is disassembled, the clamping wing 4 can automatically rotate and return to a horizontal state under the action of the tension spring. At the same time, the tension spring generates a certain resistance force to prevent the clamping wings 4 from clamping the photovoltaic panel 20 too tightly, causing damage to the photovoltaic panel 20, so that the clamping wings 4 can better fit the clamping of the photovoltaic panel 20.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
