Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, and more specifically, to a solar photovoltaic panel coating and protection tool. Background Art

[0002] Solar photovoltaic panels refer to devices that use the photovoltaic effect of semiconductor materials under light conditions to directly convert solar energy into electrical energy. They are the most direct way of utilizing solar energy. Most of their materials are silicon. Solar photovoltaic panels are a renewable energy device that does not pollute the environment.

[0003] The core of solar photovoltaic panels is crystalline silicon wafers, whose surface is very fragile and easily damaged. They are usually placed in outdoor environments, and their surfaces are easily contaminated by dust, water vapor and rain. In order to protect the surface of photovoltaic panels and prevent pollutants from entering the interior of photovoltaic panels, photovoltaic panels usually need to be coated to ensure the normal operation of photovoltaic panels.

[0004] At present, when performing coating and maintenance operations on photovoltaic panels, it is usually necessary to use a roller to evenly spread the paint on the surface of the photovoltaic panel. However, after the paint is applied, excess and unevenly applied paint will remain on the surface of the photovoltaic panel, which will cause the workers to frequently absorb the excess paint during the coating and maintenance, further making the coating and maintenance operation steps cumbersome and the coating and maintenance efficiency low, so it needs to be improved and optimized.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 7 As shown, the utility model provides a solar photovoltaic panel coating tool, comprising a handle 1, a connecting rod 2 is fixedly installed at the bottom of the handle 1, a mounting block 3 is fixedly installed at the bottom of the connecting rod 2, and a roller 4 is rotatably installed on the right side of the mounting block 3;

[0028] A mounting groove 5 is provided inside the mounting block 3, and mounting holes 6 are provided on the front and rear sides of the mounting groove 5. A fixing block 8 is detachably installed inside the mounting groove 5, a connecting block 7 is fixedly installed on the left side of the fixing block 8, a fixing rod 13 is fixedly installed inside the connecting block 7, a rotating rod 14 is rotatably connected to the outer wall of the fixing rod 13, a roller 15 is rotatably installed on the right side of the rotating rod 14, a pressing plate 16 is fixedly installed on the top of the rotating rod 14, a resist plate 17 is fixedly installed inside the connecting block 7, and the pressing plate 16 and the resist plate 17 are elastically connected by a spring 18.

[0029] When it is necessary to carry out coating and protection operation on the solar photovoltaic panel, the staff first installs the roller 2 15. At this time, the staff picks up the connecting block 7 and ensures that the roller 2 15 is located under the roller 1 4. Then, the fixing block 8 on the right side of the connecting block 7 and the mounting groove 5 are aligned with each other, and the fixing block 8 is buckled into the inside of the mounting groove 5. When the fixing block 8 and the mounting groove 5 are in contact, the inner wall of the mounting groove 5 and the fixing head 12 conflict with each other, and due to the design of the inclined surface of the fixing head 12, the fixing head 12 will be pushed by the inner wall of the mounting groove 5, and the fixing head 12 is further received into the inside of the fixing block 8. At this time, the fixing head 12 will squeeze the notch 9 through the movable rod 10. After the connecting block 7 and the mounting block 3 are fitted with each other, the fixing head 12 moves to the mounting hole 6. After losing the conflict with the inner wall of the mounting block 3, the elastic potential energy of the notch 9 pushes the fixing head 12, so that the fixing head 12 is buckled into the mounting hole 6 to complete the fixation. If it is necessary to remove the connecting block 7, , the staff only needs to use two fingers to press the fixing head 12 inward through the installation hole 6 to retract the fixing head 12 into the inside of the fixing block 8, and then pull out the connecting block 7 to complete the disassembly. After the installation of the roller 2 15 is completed, the staff pulls the extension rod 20 upward to extend the extension rod 20 to a position suitable for coating and protection work, and then rotates the screw 22 to make the screw 22 pass through the inside of the fixing hole 19 and fix the extension rod 20 and the handle 1. At this time, the painting operation can be started. After the staff sprays the paint on the surface of the roller 1 4, the roller 1 4 and the surface of the photovoltaic panel are fitted together. At this time, the roller 2 15 will also fit the photovoltaic panel, and the rotating rod 14 will rotate along the fixing rod 13 to a suitable position. When the rotating rod 14 rotates, the pressure plate 16 will squeeze the spring 2 18, and through the elastic potential energy of the spring 2 18, the roller 2 15 will always fit the surface of the photovoltaic panel to absorb excess paint.

[0030] Through the elastic potential energy of the notch 9, the fixing head 12 fixes the mounting block 3 and the connecting block 7, and then through the elastic potential energy of the spring 2 18, when the roller 1 4 is performing the coating operation, the roller 2 15 always contacts the photovoltaic panel to absorb the uneven and excess paint. Compared with the traditional device, the device enables the roller 2 15 to be quickly installed and disassembled as needed through the design of the fixing block 8 and the mounting groove 5, and the coating operation is completed at one time through the coordinated operation between the roller 1 4 and the roller 2 15, which effectively improves the coating efficiency.

[0031] The outer wall of the handle 1 is movably sleeved with an extension rod 20;

[0032] The outer wall of the handle 1 is provided with fixing holes 19, and there are six groups of fixing holes 19, which are vertically arranged on the outer wall of the handle 1. A control block 21 is fixedly installed on the outer wall of the extension rod 20, and a screw 22 is sleeved on the internal thread of the extension rod 20. One end of the screw 22 is located on the outer wall of the control block 21, and the other end passes through the control block 21 and the fixing holes 19, and is located inside the handle 1.

[0033] After the roller 15 is installed, the worker pulls the extension rod 20 upward to extend the extension rod 20 to a position suitable for coating work, and then rotates the screw rod 22 to pass through the fixing hole 19 and fix the extension rod 20 and the handle 1. At this time, the painting operation can begin.

[0034] By setting the extension rod 20, the gripping length can be adjusted. By rotating the screw rod 22, the screw rod 22 passes through the fixing hole 19 and fixes the extension rod 20 and the handle 1. Compared with the traditional device, the device can extend the extension rod 20 to the length that is most comfortable for the staff to grip for coating and maintenance operations, thereby alleviating the work burden of the staff.

[0035] Among them, slots 9 are opened on the front and back sides inside the fixed block 8, and a movable rod 10 is movably installed inside the slot 9. One end of the movable rod 10 and the inner wall of the slot 9 are elastically connected through a spring 11.

[0036] When the fixing head 12 moves to the mounting hole 6 and loses the resistance of the inner wall of the mounting block 3 , the elastic potential energy of the notch 9 pushes the fixing head 12 so that the fixing head 12 is buckled into the mounting hole 6 to complete the fixation.

[0037] Among them, one end of the two groups of movable rods 10 is fixedly installed with a fixing head 12, and the fixing head 12 is slidably installed on the front and rear sides inside the fixing block 8. The two groups of fixing heads 12 are located inside the mounting hole 6.

[0038] If it is necessary to remove the connecting block 7, the staff only needs to use two fingers to press the fixing head 12 inward through the mounting hole 6 to retract the fixing head 12 into the interior of the fixing block 8, and then pull out the connecting block 7 to complete the disassembly.

[0039] The shape of the fixing head 12 is a right-angled trapezoid, with its inclined surface facing the right side.

[0040] Among them, roller 1 4 uses high-density sponge, and the outside of the sponge is covered with microfiber cloth, which is responsible for coating and protection.

[0041] Among them, the roller 2 15 adopts nylon cloth and is responsible for absorbing excess paint.

[0042] The working principle and use process of this utility model:

[0043] When it is necessary to carry out coating and protection operation on the solar photovoltaic panel, the staff first installs the roller 2 15. At this time, the staff picks up the connecting block 7 and ensures that the roller 2 15 is located under the roller 1 4. Then, the fixing block 8 on the right side of the connecting block 7 and the mounting groove 5 are aligned with each other, and the fixing block 8 is buckled into the inside of the mounting groove 5. When the fixing block 8 and the mounting groove 5 are in contact, the inner wall of the mounting groove 5 and the fixing head 12 conflict with each other, and due to the design of the inclined surface of the fixing head 12, the fixing head 12 will be pushed by the inner wall of the mounting groove 5, and the fixing head 12 is further received into the inside of the fixing block 8. At this time, the fixing head 12 will squeeze the notch 9 through the movable rod 10. After the connecting block 7 and the mounting block 3 are fitted with each other, the fixing head 12 moves to the mounting hole 6. After losing the conflict with the inner wall of the mounting block 3, the elastic potential energy of the notch 9 pushes the fixing head 12, so that the fixing head 12 is buckled into the mounting hole 6 to complete the fixation. If it is necessary to remove the connecting block 7, , the staff only needs to use two fingers to press the fixing head 12 inward through the installation hole 6 to retract the fixing head 12 into the inside of the fixing block 8, and then pull out the connecting block 7 to complete the disassembly. After the installation of the roller 2 15 is completed, the staff pulls the extension rod 20 upward to extend the extension rod 20 to a position suitable for coating and protection work, and then rotates the screw 22 to make the screw 22 pass through the inside of the fixing hole 19 and fix the extension rod 20 and the handle 1. At this time, the painting operation can be started. After the staff sprays the paint on the surface of the roller 1 4, the roller 1 4 and the surface of the photovoltaic panel are fitted together. At this time, the roller 2 15 will also fit the photovoltaic panel, and the rotating rod 14 will rotate along the fixing rod 13 to a suitable position. When the rotating rod 14 rotates, the pressure plate 16 will squeeze the spring 2 18, and through the elastic potential energy of the spring 2 18, the roller 2 15 will always fit the surface of the photovoltaic panel to absorb excess paint.
