Description

Technical Field

[0001] The utility model relates to the field of photovoltaic component cleaning, in particular to a dual-mode photovoltaic component cleaning device. Background Art

[0002] Dual-mode photovoltaic modules, also known as bifacial photovoltaic modules, are a special photovoltaic module design. Unlike traditional photovoltaic modules that can only use the light incident on the front, the back of bifacial photovoltaic modules also has the ability to convert light into electricity. This module can absorb sunlight from both the front and back, thereby improving the efficiency of photoelectric conversion and increasing power generation.

[0003] Photovoltaic panels refer to facilities that use the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity. The core of photovoltaic facilities is solar panels.

Therefore, the photovoltaic panels need to be cleaned regularly. However, the current automated photovoltaic panel cleaning device has a relatively complex structure, inconvenient maintenance, and high manufacturing cost. Therefore, it is necessary to improve the prior art. Application number: CN202022004038.X, discloses a photovoltaic panel cleaning device, which can automatically clean photovoltaic panels, and has a simple structure, convenient maintenance, and low manufacturing cost.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a dual-mode photovoltaic module cleaning device provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the rear view of the bracket shown; Figure 3 for Figure 1A schematic diagram of the structure of the sliding frame portion shown; Figure 4 for Figure 3 A schematic diagram of the structure of a rear view of a portion of the sliding frame shown; Figure 5 for Figure 4 The enlarged schematic diagram of the structure of area A shown in the figure shows a dual-mode photovoltaic module cleaning device, comprising: a bracket 1, a cleaning component 2 is arranged on the top of the bracket 1, and an auxiliary cleaning component 3 is arranged on the inner side of the cleaning component 2;

[0024] The cleaning assembly 2 includes a fixed frame 21 which is arranged on the top of the bracket 1 in a mirror image. A sliding frame 22 is arranged on the opposite side of the two fixed frames 21 so as to slide left and right along the length direction thereof. A hollow plate 23 is arranged on the inner side of the sliding frame 22 so as to slide forward and backward. Two sliding rods 24 are arranged on the bottom of the hollow plate 23 so as to slide up and down. A cleaning sponge 25 is arranged at the bottom of the two sliding rods 24.

[0025] Photovoltaic panels are arranged at the top of the bracket 1 and at the bottom on the opposite side of the two fixing frames 21. The sliding frame 22 slides left and right along the groove of the fixing frame 21, driving the cleaning sponge 25 to move left and right on the photovoltaic panel, thereby cleaning it. When the cleaning sponge 25 stops moving, it will be inside the pool 4, and the cleaning effect of water is better.

[0026] The auxiliary cleaning component 3 includes racks 31 arranged on the top of both sides of the hollow plate 23, a placement plate 32 is slidably provided on the opposite side of the two fixed frames 21, and two connecting gears 33 are rotatably provided on the left and right sides of the bottom of the placement plate 32. The bottom of the two connecting gears 33 is provided with half gears 34, and the two half gears 34 are respectively engaged with the two racks 31.

[0027] The rotation of the output end of the first motor 36 drives the gear 35 to rotate, and then drives the two connecting gears 33 to rotate. The two connecting gears 33 drive the half gears 34 at their bottoms to rotate. Whenever the half gear 34 on one side pushes the rack 31 to move to one side, the half gear 34 on the other side will push the rack 31 to reset, thereby causing the hollow plate 23 to move back and forth on the inner side of the sliding frame 22, so that the cleaning sponge 25 moves left and right on the surface of the photovoltaic panel and moves back and forth at the same time, achieving a better cleaning effect.

[0028] A gear 35 is disposed at the bottom of the placement plate 32 and on a side opposite to the two connecting gears 33 . The gear 35 meshes with the side opposite to the two connecting gears 33 .

[0029] The two connecting gears 33 are rotationally connected to the placement plate 32 , and the half gears 34 at the bottom of the two connecting gears 33 are fixedly connected to the corresponding connecting gears 33 .

[0030] A first motor 36 for driving the gear 35 to rotate is provided at the top of the placement plate 32 . The output end at the bottom of the first motor 36 passes through the top of the placement plate 32 and extends to the bottom thereof. The output end at the bottom of the first motor 36 is fixedly connected to the top of the gear 35 .

[0031] The cleaning assembly 2 further comprises a water pool 4 arranged on the left side of the top of the bracket 1 and located on the top of the cleaning sponge 25 , and a spring 5 is arranged on the peripheral side of the two sliding rods 24 and located on the top of the cleaning sponge 25 .

[0032] The edge of the pool 4 is inclined. When the cleaning sponge 25 moves, its angle matches the angle of the edge of the pool 4 , thereby changing the force direction, so that the spring 5 retracts and the cleaning sponge 25 can enter the pool 4 .

[0033] A rotating screw rod 26 is laterally arranged on the inner side of the two fixed frames 21, and the peripheral side surfaces of the two rotating screw rods 26 are respectively threadedly connected to the front and rear sides of the sliding frame 22. The right ends of the two rotating screw rods 26 pass through the inner side of the fixed frame 21 and extend to the right side thereof. The right ends of the two rotating screw rods 26 are provided with oblique teeth. A rotating frame 27 is arranged on the right side of the two fixed frames 21. A connecting rod 28 is rotatably arranged on the opposite side of the two rotating frames 27. The peripheral side surface of the connecting rod 28 is meshed with the right ends of the two rotating screw rods 26 by being provided with oblique teeth.

[0034] The rotation of the output end of the second motor 29 drives the connection rod 28 to rotate, and then the setting of the oblique teeth drives the two rotating screws 26 to rotate synchronously, driving the sliding frame 22 to slide left and right on the fixed frame 21.

[0035] A second motor 29 for driving the connecting rod 28 to rotate is provided on the inner side of the bracket 1 and below the front fixing frame 21 , and the output end of the second motor 29 is connected to the front end belt of the connecting rod 28 .

[0036] The working principle of a dual-mode photovoltaic module cleaning device provided by the utility model is as follows:

[0037] Step 1: When the surface of the photovoltaic panel needs to be cleaned, the rotation of the output end of the second motor 29 drives the connection rod 28 to rotate, and then drives the two rotating screws 26 to rotate synchronously, so that the sliding frame 22 slides left and right along the direction of the fixed frame 21, and the cleaning sponge 25 moves left and right on the surface of the photovoltaic panel;

[0038] Step 2: During the movement of the cleaning sponge 25, the rotation of the output end of the first motor 36 drives the rotation of the gear 35, which in turn drives the rotation of the two connecting gears 33, which drives the rotation of the two half gears 34, and then the two half gears 34 respectively mesh with the rack 31 intermittently, driving the hollow plate 23 to reciprocate back and forth inside the sliding frame 22, so that the cleaning sponge 25 moves left and right on the surface of the photovoltaic panel and moves forward and backward at the same time, which significantly improves the cleaning effect;

[0039] Step 3: During the cleaning process, the cleaning sponge 25 is pressed against the photovoltaic panel by the setting of the sliding rod 24 and the spring 5 to improve the cleaning effect. When the cleaning is completed and the assembly returns to the initial position, since the edge of the pool 4 is inclined, when the cleaning sponge 25 moves, its own angle coincides with the angle of the edge of the pool 4, thereby changing the force direction, so that the spring 5 retracts and the cleaning sponge 25 can enter the pool 4 to soak and wait for the next cleaning.

[0040] Compared with the related art, the dual-mode photovoltaic module cleaning device provided by the utility model has the following beneficial effects:

[0041] The rotation of the output end of the first motor 36 drives the gear 35 to rotate, which in turn drives the two connecting gears 33 to rotate, and drives the two half gears 34 to rotate. Then, the two half gears 34 respectively and intermittently mesh with the rack 31, driving the hollow plate 23 to reciprocate back and forth inside the sliding frame 22, so that the cleaning sponge 25 moves left and right on the surface of the photovoltaic panel and moves forward and backward at the same time. The structure is simple and practical, which effectively improves the cleaning effect of the photovoltaic panel and improves the conversion rate of the photovoltaic panel.

[0042] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
