Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and more specifically to an automatic cleaning device for photovoltaic panels. Background Technology

[0002] Photovoltaic panels, also known as solar panels, are assemblies consisting of several solar cell modules assembled on a single panel in a specific manner, and are typically used as a unit in a photovoltaic array.

[0003] Individual solar cells cannot be used directly as power sources. To function as power sources, several individual cells must be connected in series and parallel and tightly packaged into a module. Solar cell modules (also called solar panels) are the core and most important component of a solar power generation system. Their function is to convert solar energy into electrical energy, which can then be either stored in batteries or used to power loads. The quality and cost of the solar panels directly determine the quality and cost of the entire system.

[0004] However, since photovoltaic panels are placed outdoors, dust easily accumulates on their surface, affecting the photoelectric conversion effect and potentially reducing the power generation efficiency of the photovoltaic panels by as much as 35%-40%.

[0005] Therefore, how to provide an automatic photovoltaic panel cleaning device that can automatically clean photovoltaic panels and achieve good cleaning results is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides an automatic cleaning device for photovoltaic panels, which aims to solve the problems in the background art and achieve automatic and efficient cleaning of photovoltaic panels.

[0027] See Figure 1 and 2 The present invention discloses an automatic photovoltaic panel cleaning device, comprising: a base plate 1, a top support plate 3, a bottom support plate 4, a cleaning component 5, and a power component 6.

[0028] A photovoltaic panel 2 is inclinedly arranged above a base plate 1. A top support plate 3 is fixedly connected to one end of the base plate 1 and perpendicular to the base plate 1, supporting the top of the photovoltaic panel 2. A bottom support plate 4 is fixedly connected to the end of the base plate 1 away from the top support plate 3, supporting the bottom of the photovoltaic panel 2. A cleaning component 5 is slidably connected to the photovoltaic panel 2. One end of a power component 6 is connected to the base plate 1, and the other end of the power component 6 is connected to the cleaning component 5. Driven by the power component 6, the cleaning component 5 slides on the photovoltaic panel 2 to clean the photovoltaic panel 2. In this embodiment, the base plate 1 is connected to the ground and is used to support and fix the top support plate 3 and the bottom support plate 4. The top support plate 3 and the bottom support plate 4 are used to support and fix the top and bottom of the photovoltaic panel 2, respectively. The power component 6 is used to provide power to the cleaning device, and the cleaning component 5 is used to clean the working surface of the photovoltaic panel 2.

[0029] The cleaning component 5 includes a movable frame 51, a water storage tank 52, a brush roller 53, a sliding wheel 54, and a scraper 55. The movable frame 51 is hinged to the brush roller 53, the sliding wheel 54, and the power component 6. The brush roller 53 rolls on the upper surface of the photovoltaic panel 2, and the sliding wheel 54 rolls on the lower surface of the photovoltaic panel 2. The water storage tank 52 is fixedly connected to the movable frame 51 and is located above the brush roller 53. The bottom of the water storage tank 52 is provided with a water permeable hole 521. The scraper 55 is connected to the water storage tank 52, and one end of the scraper 55 away from the water storage tank 52 rests against the photovoltaic panel 2. In this embodiment, the water storage tank 52 is used to store rainwater or dew. During operation, the movable frame 51 slides along the direction of the photovoltaic panel 2, and the water storage tank 52 sprays water onto the surface of the photovoltaic panel 2 through the water permeable hole 521. During the sliding process of the movable frame 51, the brush roller 53 can brush away the dirt and dust on the surface of the photovoltaic panel 2, and then the scraper 55 can scrape away the water generated by the photovoltaic panel 2.

[0030] The movable frame 51 includes a first connecting rod 511, a second connecting rod 512, a third connecting rod 513, and a fourth connecting rod 514. The first connecting rod 511, the second connecting rod 512, the third connecting rod 513, and the fourth connecting rod 514 are sequentially hinged to form a quadrilateral structure. The brush roller 53 is located at the hinge of the first connecting rod 511 and the second connecting rod 512.

In this embodiment, the support hydraulic cylinder 62 is used to support the cleaning assembly 5, and the power hydraulic cylinder 61 is used to provide power for the movement of the cleaning assembly 5. During operation, the power hydraulic cylinder 61 pulls or pushes the middle part of the support hydraulic cylinder 62, causing the power hydraulic cylinder 61 to contract or extend. The support hydraulic cylinder 62 can reciprocate. During the reciprocating swing of the support hydraulic cylinder 62, the support hydraulic cylinder 62 drives the cleaning assembly 5 to slide along the photovoltaic panel 2, thereby achieving the technical effect of driving the cleaning assembly 5 to clean the photovoltaic panel 2.

[0033] A water collection plate 7 is provided at the end of the bottom support plate 4 away from the bottom plate 1. The water collection plate 7 includes an inclined plate 71 and a connecting plate 72. The connecting plate 72 is connected to the bottom support plate 4 and is vertically arranged. The inclined plate 71 is connected to the end of the connecting plate 72 away from the bottom support plate 4. The inclined plate 71 is inclined towards the photovoltaic panel 2. In this embodiment, the water collection plate 7 is used to collect rainwater and dew. The bottom of the inclined plate 71 is close to the water storage tank 52. The inclined plate 71 can guide rainwater and dew into the water storage tank 52.

[0034] A first support 31 is provided at the end of the top support plate 3 away from the bottom plate 1.
