Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel accessories, specifically an installation structure for a photovoltaic panel cleaning brush. Background Technology

[0002] During long-term use, photovoltaic panels are exposed to the air for extended periods, which causes dust to accumulate on their surface, affecting their power generation efficiency. Therefore, it is necessary to clean the surface of photovoltaic panels regularly.

[0003] If photovoltaic panels are installed over a large area, the cleaning brushes often need to be cleaned multiple times to ensure the quality of the cleaning process. However, repeated cleaning can waste a lot of time and may not guarantee the cleaning quality of the brushes. As a result, the brushes may carry uncleaned dust into subsequent cleaning operations, which is detrimental to the cleaning quality of the photovoltaic panels. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an installation structure for a photovoltaic panel cleaning brush that is easy to disassemble and replace, thereby improving the cleaning efficiency and quality of photovoltaic panels.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: an installation structure for a photovoltaic panel cleaning brush, including a connecting frame and a fixing frame. The fixing frame is fixedly connected to one side of the connecting frame. The side of the connecting frame away from the fixing frame is used to fixally connect a cleaning brush strip. The fixing frame is used to fixally connect to a drive rod. One end of the fixing frame is embedded in the connecting frame. The other end of the fixing frame is fixedly connected to the connecting frame through a pull-locking assembly. The pull-locking assembly includes a pull tab. One end of the pull tab is located on the outside of the connecting frame for pull-out operation. The other end of the pull tab is located on the inside of the connecting frame, and the other end of the pull tab is provided with a control pin. The pull tab controls the control pin to insert into or move away from the fixing frame through the pull-out operation.

[0006] Compared with the prior art, the advantages of this utility model are as follows: Through the design of the pull-locking component, when it is necessary to replace the cleaning brush strip, simply pull the pull tab to move the control pin away from the fixed frame, release the control pin from the fixed frame, and separate the fixed frame from the connecting frame. Then, the connecting frame with the cleaning brush strip can be directly replaced. The pull tab design makes the control structure more prominent, making it easier to apply force to the pull tab to control the control pin, thereby achieving the purpose of easy replacement of the cleaning brush strip. After the cleaning brush strip is replaced, the control drive rod can then perform the cleaning operation of the photovoltaic panel, which can avoid the cleaning brush strip carrying dust during the cleaning operation, thus ensuring cleaning efficiency and cleaning quality. After the cleaning operation of all photovoltaic panels is completed, the cleaning brush strips on multiple connecting frames can be disassembled and cleaned uniformly. At this time, the cleaning effect of the cleaning brush strip can be better guaranteed, and dust on the cleaning brush strip can be avoided, thereby improving the cleaning efficiency and cleaning quality of the cleaning brush strip.

[0007] As an improvement of this utility model, the connecting frame is provided with a limiting hole for the movement of the control pin, and the fixing frame is provided with a fixing hole for the control pin to be inserted. When the fixing frame and the connecting frame are connected and fixed, the fixing hole is located on the extension line of the limiting hole towards the fixing frame. Through this improvement, the design of the limiting hole can ensure the stability of the movement direction of the control pin. When the fixing frame needs to be fixedly connected to the connecting frame, the control pin can move along the limiting hole towards the fixing hole until the control pin is inserted into the fixing hole to complete the fixed connection between the fixing frame and the connecting frame.

[0008] As an improvement of this utility model, a spring connecting post is provided on the side of the actuating piece away from the control pin. A spring is sleeved on the spring connecting post. One end of the spring abuts against the connecting frame, and the other end of the spring abuts against the actuating piece. Through this improvement, the spring can automatically reset the control pin after it is actuated. At the same time, under the action of the spring, the control pin can be kept in its normal position to ensure the stability of the fixed connection between the fixing frame and the connecting frame. The design of the spring connecting post can ensure the stability of the spring under force and ensure the direction of the spring force, avoiding the actuating piece from tilting or the spring from tilting.

[0009] As an improvement of this utility model, the end of the control pin near the fixed frame is provided with an insertion inclined surface, the fixed hole is provided on a fixed block, and the end of the fixed block near the connection side of the connecting frame and the fixed frame is provided with an installation inclined surface. Through this improvement, the design of the insertion inclined surface not only facilitates the better insertion of the control pin into the fixed hole, but also facilitates the installation inclined surface to push the control pin along the insertion inclined surface when the fixed frame is installed on the connecting frame, so that the control pin retracts into the connecting frame until the fixed frame is installed in place, the fixed hole reaches the extension line of the limit hole, the control pin is reset and inserted into the fixed hole.

[0010] As an improvement of this utility model, a mounting base is fixedly connected inside the connecting frame. One end of the mounting base is used to splice with the connecting frame to form a limiting hole, and the other end of the mounting base is used to splice with the connecting frame to form a directional hole. The directional hole is used to move and connect with the spring connecting column. Through this improvement, the limiting hole and the directional hole are formed, ensuring that the control pin moves and connects along the limiting hole and the spring connecting column moves and connects along the directional hole, thereby ensuring the stability of the movement of the pull plate and preventing it from deviating or turning. At the same time, the installation of the pull plate inside the connecting frame is also realized.

[0011] As an improvement of this utility model, the inner wall of the connecting frame is provided with mounting buckles on both sides to prevent the mounting seat from detaching from the connecting frame, and the two ends of the mounting seat are provided with limiting ribs to restrict the movement of the mounting seat on the connecting frame. Through the improvement, the mounting seat is fixedly connected.

[0012] As an improvement of this utility model, the connecting frame is provided with a pulling hole for the pulling plate to move, and the pulling plate is provided with a sealing block for sealing the pulling hole when the fixed frame and the connecting frame are fixedly connected. Through this improvement, it is prevented that dust will enter the connecting frame during use, thus affecting the quality of the cleaning brush.

[0013] As an improvement of this utility model, a spring is provided between the connecting side of the fixed frame and the connecting frame. With this improvement, after the control pin moves away from the fixed frame, the spring can pop out the fixed frame to realize the quick separation of the fixed frame and the connecting frame, which facilitates the disassembly of the cleaning brush.

[0014] As an improvement of this utility model, the other end of the fixing frame is provided with an arc-shaped protrusion. The arc-shaped protrusion is located on the side of the fixing frame away from the spring and is used to abut against the connecting frame. With this improvement, during the process of the spring popping out of the fixing frame, the arc-shaped protrusion can serve as a rotation fulcrum for the fixing frame, which facilitates the safe popping out of the fixing frame and avoids deformation and damage at the contact point between the fixing frame and the connecting frame.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-2 As shown, an installation structure for a photovoltaic panel cleaning brush includes a connecting frame 1 and a fixing frame 2. The fixing frame 2 is fixedly connected to one side of the connecting frame 1. The side of the connecting frame 1 away from the fixing frame 2 is used to fix a cleaning brush strip. The fixing frame 2 is used to fixably connect to a drive rod. One end of the fixing frame 2 is embedded in the connecting frame 1, and the other end of the fixing frame 2 is fixedly connected to the connecting frame 1 by a pull-locking assembly 3. The pull-locking assembly 3 includes a pull tab 3.1, one end of which is located on the outside of the connecting frame 1 for pull-out operation. The other end of the actuating piece 3.1 is located inside the connecting frame 1, and the other end of the actuating piece 3.1 is provided with a control pin 3.1.1. The actuating piece 3.1 controls the control pin 3.1.1 to insert into or move away from the fixed frame 2 by actuating operation. The fixed frame 2 is provided with a connecting post 2.4 fixedly connected to the drive rod. The connecting frame 1 is provided with a connecting groove for fixing and connecting the cleaning brush strip. The drive rod and the cleaning brush strip are both conventional cleaning accessories. The drive rod can be a handheld rod for manual cleaning operations or a transmission connecting rod for automatic cleaning operations.

[0023] like Figure 2-4As shown, the connecting frame 1 has a limiting hole 1.1 for the movement of the control pin 3.1.1, and the fixing frame 2 has a fixing hole 2.1 for insertion into the control pin 3.1.1. When the fixing frame 2 is connected and fixed to the connecting frame 1, the fixing hole 2.1 is located on the extension line of the limiting hole 1.1 towards the fixing frame 2. The side of the actuating piece 3.1 away from the control pin 3.1.1 has a spring connecting post 3.1.2, and a return spring 3.2 is sleeved on the spring connecting post 3.1.2. One end of the return spring 3.2 abuts against the connecting frame 1, and the other end of the return spring 3.2 abuts against the actuating piece 3.1. The end of the control pin 3.1.1 near the fixing frame 2 has an insertion inclined surface 3.1.1.1. The fixing hole 2.1 is located on a fixing block 2.2, and the end of the fixing block 2.2 near the connection side of the connecting frame 1 and the fixing frame 2 has an installation inclined surface 2.2.1.

[0024] A mounting base 4 is fixedly connected inside the connecting frame 1. One end of the mounting base 4 is used to splice with the connecting frame 1 to form a limiting hole 1.1, and the other end of the mounting base 4 is used to splice with the connecting frame 1 to form a directional hole 1.2. The directional hole 1.2 is used for movable connection with the spring connecting post 3.1.2. The inner wall of the connecting frame 1 is provided with mounting buckles 1.3 on both sides to prevent the mounting base 4 from detaching from the connecting frame 1. Both ends of the mounting base 4 are provided with limiting ribs 1.4 to restrict the movement of the mounting base 4 on the connecting frame 1. The lower end of the mounting buckle 1.3 is provided with an inclined surface to facilitate the embedding of the mounting base 4 into the connecting frame 1.

[0025] like Figure 1-3 As shown, the connecting frame 1 is provided with a pulling hole 1.5 for the moving piece 3.1, and the pulling piece 3.1 is provided with a closing block 3.1.3 for closing the pulling hole 1.5 when the fixed frame 2 and the connecting frame 1 are fixedly connected.

[0026] like Figure 2 , Figure 5 As shown, a push-out spring 5 is provided between the connecting side of the fixed frame 2 and the connecting frame 1. An arc-shaped protrusion 2.3 is provided at one end of the fixed frame 2 that is embedded in the connecting frame 1. The arc-shaped protrusion 2.3 is located on the side of the fixed frame 2 away from the spring and is used to abut against the connecting frame 1.

[0027] When the cleaning brush strip needs to be replaced, simply pull the actuating piece 3.1 along the direction of the actuating hole 1.5 to disengage the control pin 3.1.1 from the fixing hole 2.1. Then, under the action of the ejection spring 5, the fixing bracket 2 pops out the connecting bracket 1 around the arc-shaped protrusion 2.3. Manually separate the connecting bracket 1 from the fixing bracket 2, and then reverse the operation to install the connecting bracket 1 with the cleaning brush strip that has not been used for cleaning onto the fixing bracket 2. However, it is not necessary to pull the actuating piece 3.1 during the installation process. When the connecting bracket 1 is inserted, the other end of the fixing bracket 2 is pressed around the arc-shaped protrusion 2.3. At this time, the mounting inclined surface 2.2.1 pushes the control pin 3.1.1 along the insertion inclined surface 3.1.1.1 to move, so that the control pin 3.1.1 retracts into the connecting bracket 1 until the fixing bracket 2 is installed in place and the fixing hole 2.1 reaches the extension line of the limit hole 1.1. The control pin 3.1.1 is reset under the action of the return spring 3.2 and inserted into the fixing hole 2.1, thus completing the installation of the fixing bracket 2 on the connecting bracket 1.
