Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning, in particular to a cleaning component for solar photovoltaic panels. Background Art

[0002] Photovoltaic panel assemblies are power generation devices that generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Photovoltaic panel assemblies are used on rooftops and building surfaces, and are even used as part of windows, skylights or shading devices. These photovoltaic facilities are usually referred to as building-attached photovoltaic systems.

[0003] Existing photovoltaic panels are usually arranged together. Photovoltaic panels have too much dust on their surfaces due to long-term use and need to be cleaned. Photovoltaic panels are usually cleaned by manual operation of cleaning tools such as electric mops. Since there are many photovoltaic panels, they need to be cleaned in sequence according to the arrangement, which results in high work intensity, time-consuming and labor-intensive. When cleaning is performed by operating cleaning tools, the cleaning surface of the tools is small, and some positions are not cleaned evenly, which easily leads to secondary pollution and causes poor cleaning effect. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a cleaning component for solar photovoltaic panels, which reduces the workload of cleaning photovoltaic panels, makes the cleaning more comprehensive, and is less likely to cause secondary pollution, thereby achieving a better cleaning effect.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cleaning assembly for solar photovoltaic panels comprises a horizontal frame for erecting on a photovoltaic panel body, the top end of the lower surface of the horizontal frame being fixedly connected to a first side plate, and the bottom end of the lower surface of the horizontal frame being provided with a second side plate, limiting wheels being provided in the second side plate and the first side plate, and the limiting wheels are in contact with the outer wall of the photovoltaic panel body, a motor is fixedly installed on the top end of the upper surface of the horizontal frame, a gear set is provided at the bottom end of the motor, and the motor is transmitted to the limiting wheel in the first side plate through the gear set, a scraper is provided in the horizontal frame, a pull rod is slidably sleeved on the bottom end of the horizontal frame, one end of the pull rod passes through the inner wall edge of the horizontal frame and is fixedly connected to the second side plate, and a spring sleeved on the outer wall of one end of the pull rod is fixedly connected between the second side plate and the inner wall edge of the horizontal frame.

[0007] Preferably, the pull rod is designed as a "U"-shaped structure, and one end of the pull rod away from the spring is slidably sleeved in the bottom end of the cross frame.

[0008] Preferably, rollers are arranged on both sides of the lower surface of the horizontal frame, and the outer walls of the rollers are wrapped with a rubber layer.

[0009] Preferably, the second side plate is designed as an "L"-shaped structure, and two balls are arranged on the upper surface of the second side plate to abut against the bottom of the photovoltaic panel body.

[0010] Preferably, rubber scrapers are clamped on the four sides of the scraper, and the shafts at both ends of the scraper are connected to the inner wall of the cross frame through bearings.

[0011] Preferably, positioning holes are formed on four sides of one end of the scraper, a threaded rod is threadedly connected to the upper surface of the cross frame, and the bottom end of the threaded rod is clamped in one of the positioning holes.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By respectively arranging the first side plate and the second side plate at both ends of the lower surface of the horizontal frame, and the second side plate can be elastically reset under the pull of the pull rod through the action of the spring, it is convenient to quickly set up the horizontal frame on the photovoltaic panel body and remove it at any time. The two corresponding limiting wheels are fitted with the two sides of the photovoltaic panel body, so that the horizontal frame can slide on the photovoltaic panel body, which is convenient for using the scraper and the rubber scraper to scrape and clean the photovoltaic panel body. At the same time, the motor and the gear set can drive the limiting wheel fitted with the top of the inclined surface of the photovoltaic panel body to rotate automatically, so as to drive the horizontal frame to automatically slide and clean the photovoltaic panel body quickly and evenly. The cleaning component is easy to install and use quickly, which reduces the work intensity for cleaning the photovoltaic panel, and the cleaning is more comprehensive, not easy to form secondary pollution, so that the cleaning effect is better.

[0014] 2. The scraper is connected to the cross frame through a bearing so that the scraper can rotate. Rubber scrapers for cleaning dust are set on the four sides of the scraper. The scraper can be rotated and connected to the positioning hole with a threaded rod to fix it. The rubber scrapers on the four sides of several scrapers can be used in turn to prevent the outer wall of a single rubber scraper from sticking too much dust and affecting the cleaning effect of the photovoltaic panel.

[0022] Specifically, Figure 2 and Figure 4As shown, the pull rod 9 is designed as a "U"-shaped structure, and the end of the pull rod 9 away from the spring 10 is slidably sleeved in the bottom end of the cross frame 1. Through its design, the pull rod 9 is easy to operate for pulling, and at the same time, the pull rod 9 and the cross frame 1 maintain stability, making its structure compact and safer to operate. The second side panel 11 is designed as an "L"-shaped structure, and two ball bearings 12 that are against the bottom of the photovoltaic panel body 3 are arranged on the upper surface of the second side panel 11. Through its design, the ball bearings 12 can fit with the bottom of the photovoltaic panel body 3, so that when the cross frame 1 maintains contact with the photovoltaic panel body 3, the friction of the contact surface is reduced, and the sliding of the cross frame 1 is convenient.

[0023] Specifically, Figure 2 and 3 As shown, rollers 8 are arranged on both sides of the lower surface of the horizontal frame 1, and the outer walls of the rollers 8 are wrapped with a rubber layer. Through the two rollers 8, when the horizontal frame 1 is in contact with the photovoltaic panel body 3 under the action of gravity, they are connected by the rollers 8. When the horizontal frame 1 slides, the rollers 8 can roll synchronously, so that the horizontal frame 1 can slide stably on the photovoltaic panel body 3. The rollers 8 maintain soft contact with the photovoltaic panel body 3 to prevent scratches on the photovoltaic panel body 3.
