Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic heat dissipation and dust removal, and relates to a new energy photovoltaic heat dissipation and dust removal structure. Background Art

[0002] Photovoltaic modules are one of the important components of a solar power generation system, used to convert solar energy into electrical energy. Photovoltaic modules usually consist of elements such as solar cells, external brackets, glass cover layers, and backplates. Existing photovoltaic modules are composed of a solar panel and a support system, etc. The solar panel is exposed outdoors for a long time, and dust will adhere to its surface, which will affect the absorption of solar energy by the panel and requires a cleaning device to clean its surface.

[0003] Chinese Patent Publication No. CN220156479U discloses a new energy photovoltaic heat dissipation and dust removal structure. This device mainly consists of a frame and a jet component. Among them, the jet component is rotationally connected to a three-way pipe through a bearing and is equipped with multiple groups of nozzles. During operation, the airflow generated by the fan is introduced into the jet component through the three-way pipe and evenly ejected through the multiple groups of nozzles on the two jet components. These jet airflows form a flowing layer on the surface of the photovoltaic panel, which can not only directly blow away the dust particles adhering to the panel surface, but also drive the surrounding air to flow, achieving effective heat dissipation of the photovoltaic panel while removing dust, so as to achieve the dual functions of a single device for both dust removal and heat dissipation.

[0004] However, this technical solution has obvious limitations in practical applications: when the environmental humidity is high, the dust on the surface of the photovoltaic panel is easily mixed with water vapor to form sticky coagulants, and it is difficult to completely remove such mixed pollutants only by gas blowing. Especially in the rainy season or high-humidity areas, the dust removal method relying solely on air flow will be greatly reduced in effect. Therefore, it is urgent to develop an improved new energy photovoltaic heat dissipation and dust removal structure to solve the technical problem that the existing technology cannot effectively remove the dust-water mixed coagulants and improve the cleaning and maintenance effect of the photovoltaic panel in complex environments.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] As Figures 1-9 shown, the technical solution adopted by the present invention is as follows: A new energy photovoltaic heat dissipation and dust removal structure includes a support frame 1.

One end of the first spring 18 is fixedly connected to the rotating ring 15, and the other end of the first spring 18 is fixedly connected to the fixing plate 16.

[0034] A groove is formed on the upper end face of the moving column 11, a connecting elbow 19 is fixedly installed inside the moving column 11, one end of the connecting elbow 19 is communicated with the groove, the other end of the connecting elbow 19 is communicated with the storage groove 13, a telescopic pipe 20 is fixedly connected to the side of the water spraying plate 12 corresponding to the storage groove 13, and the other end of the telescopic pipe 20 is fixedly connected to the connecting elbow 19.

[0036] A support rod 22 is fixedly installed on the upper end face of the moving column 11, and a spiral blade 23 is fixedly installed at the top end of the support rod 22.

The gear 8 is meshed with the adjacent toothed plate 9.

[0038] The cleaning member 6 includes a rotating ring 24 and a cleaning brush 25.

[0039] A guide rail 26 is provided on one side of the upper end surface of the support frame 1, and a guide block 27 is slidably installed inside the guide rail 26. A water pipe 28 is fixedly installed on the guide block 27. One end of the water pipe 28 is connected to the inside of the fixed pipe 4, and the other end of the water pipe 28 is connected to an external water supply device.

[0040] In this embodiment: a receiving plate 32 is fixedly installed on the opposite surface of the two tooth plates 9, and a plurality of moving rods 33 are slidably installed on the side of the receiving plate 32 close to the opening of the support frame 1, and a baffle 34 is fixedly installed on the other end of the moving rod 33. The outer side of the moving rod 33 is sleeved with a third spring 35, one end of the third spring 35 is fixedly connected to the receiving plate 32, and the other end of the third spring 35 is fixedly connected to the baffle 34. The elastic pressure of the third spring 35 is adapted to photovoltaic panels of different thicknesses, and the baffle 34 automatically fits the edge of the plate body to prevent displacement or vibration during the cleaning process.

[0041] Working principle:

[0042] When in use, pull the baffle 34 to extend the third spring 35, place the photovoltaic solar panel on the upper end surface of the receiving plate 32, loosen the baffle 34, and allow the third spring 35 to return to its original state to drive the baffle 34 to limit the photovoltaic solar panel to prevent the photovoltaic solar panel from shaking when cleaning.

[0043] The motor 30 is started, and the output shaft of the motor 30 rotates to drive the screw 29 to rotate. The screw 29 cooperates with the thread of the slider 3 to drive the slider 3 to slide inside the slide groove 2, thereby driving the fixed pipe 4 to move on the solar panel, and the water is supplied to the water pipe 28 through the external water supply equipment, so that the water impacts the moving column 11 through the water outlet pipe 10 at the bottom side of the fixed pipe 4, and the moving column 11 is rushed out to the bottom of the water outlet pipe 10, driving the first spring 18 to extend. When the water spray plate 12 on the moving column 11 moves downward to the inside of the water outlet pipe 10, the first spring 18 is extended. The second spring 21 returns to its original state and drives the water spray plate 12 to flip toward the outside of the storage groove 13, so that the water spray plate 12 flips to the outside of the movable column 11, and the water flows into the water spray plate 12 through the connecting elbow 19 and the telescopic tube 20, and is finally discharged through the water spray hole 14; when the water flows hit the spiral blade 23, it drives the spiral blade 23 and the support rod 22 to rotate, and the rotation of the support rod 22 drives the movable column 11 to rotate, so that the movable column 11, the fixed plate 16 and the rotating ring 15 rotate synchronously, so that the water spray plate 12 can rotate to drain water while moving horizontally, so that the spraying is more uniform.

[0044] After cleaning is completed, the water flow no longer impacts the moving column 11, so that the first spring 18 returns to its original state and drives the moving column 11 back to the inside of the water outlet pipe 10, and the water spray plate 12 is stored into the storage groove 13 under the drive of the second spring 21 to restore its original state, thereby realizing the storage of the moving column 11 and the water spray plate 12 to avoid being exposed to the outside for a long time and reducing the service life.

[0045] When the fixed pipe 4 moves, it drives the gear 8 to move. The gear 8 meshes with the toothed plate 9, causing the gear 8 to rotate on its own axis while moving. The rotation of the gear 8 drives the rotation of a plurality of cleaning members 6 through the connecting rod 7, so that the cleaning brush 25 rotates during the movement to brush the solar panel, improving the cleaning effect.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
