Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning, in particular to a fixing mechanism and a photovoltaic panel cleaning device. Background Art

[0002] Photovoltaic panels are devices that generate direct current (DC) electricity when exposed to sunlight. They are composed almost entirely of thin, solid-state photovoltaic cells made from semiconductor materials (such as silicon). After prolonged use, photovoltaic panels require surface cleaning.

[0003] Existing photovoltaic panels need to be fixed before cleaning. However, ordinary rotating cleaning devices are inconvenient to clamp when placing photovoltaic panels due to the rotation of the device. At the same time, conventional photovoltaic panels are only cleaned by contacting the photovoltaic panels with a rolling brush, which has limited cleaning effect on the photovoltaic panels. When dust adheres to the surface of the photovoltaic panels, the dust cannot be completely removed. At the same time, after the photovoltaic panels are cleaned, the water droplets on the surface of the photovoltaic panels cannot be removed, which will cause the dust to adhere to the surface of the photovoltaic panels again.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it designate a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figures 1 to 3 , which is the first embodiment of the utility model, provides a fixing mechanism, including a placement component 100 and a limiting component 200. The operator places the photovoltaic panel in the placement component 100. At this time, the device clamps the photovoltaic panel. When it is not placed, the placement component 100 is relatively fixed, which is convenient for the placement of the photovoltaic panel. After it is placed and clamped, the placement component 100 is released from the fixed state and can be driven to rotate during subsequent cleaning.

[0033] Specifically, the placement assembly 100 includes a support plate 101 and a clamping member 102 , wherein the support plate 101 is fixed by bolts and vertically installed on the upper part of the frame member 303 , and the side wall of the clamping member 102 is rotatably connected to the side wall of the support plate 101 .

[0034] Furthermore, the limiting assembly 200 includes a rotating member 201 and a locking member 202 , wherein the rotating member 201 is rotatably arranged at the connection between the clamping member 102 and the support plate 101 , and the locking member 202 is arranged inside the clamping member 102 and cooperates with the rotating member 201 .

[0035] During use, the operator places the photovoltaic panel between the two clamping members 102. When the photovoltaic panel is placed, it will press down a part of the clamping member 102. At this time, the two ends of the clamping member 102 will shrink and limit and fix the parts of the photovoltaic panel, thereby clamping and fixing the photovoltaic panel. When the photovoltaic panel is not placed, the clamping member 202 is not triggered. At this time, the clamping member 102 is in a state where it cannot rotate, which is convenient for the operator to place the photovoltaic panel. Later, after clamping, the clamping member 202 is triggered to enable the rotating member 201 to rotate, which is convenient for rotating and cleaning the photovoltaic panel during subsequent cleaning.

[0036] In summary, by setting the clamping part, the photovoltaic panel can be automatically clamped when placed in the clamping part. By setting the rotating part and the locking part, the clamping part can be stable and will not rotate when the photovoltaic panel is placed, which is convenient for installation. When the photovoltaic panel is clamped, the locking part will be triggered, and the lock of the rotating part will be unlocked at this time, which is convenient for subsequent rotation cleaning and enhances the cleaning effect.

[0037] Example 2

[0038] Reference Figures 2 and 3 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment:

[0039] Specifically, the clamping member 102 includes a clamping plate 102a, a clamping block 102b and a slider 102c, wherein a cavity is provided inside the clamping plate 102a, and the slider 102c is placed in the cavity, and the clamping block 102b is movably connected to the clamping plate 102a through the slider 102c.

[0040] Preferably, the clamping block 102b has a right-angled groove inside so that when the clamping blocks 102b are moved toward each other to clamp the photovoltaic panel, they can hold the four corners of the photovoltaic panel to prevent it from falling off when flipping over for cleaning.

[0041] Furthermore, the slider 102c includes a slide rod 102c-1, a slide groove 102c-2 and a spring No. 102c-3, wherein the slide groove 102c-2 is set through the interior of the clamping plate 102a, one end of the slide rod 102c-1 is connected to the clamping block 102b, and the other end is movably set inside the slide groove 102c-2, and the spring No. 102c-3 is sleeved on the rod body of the slide rod 102c-1, and its two ends are respectively against the side walls of the slide groove 102c-2 and the slide rod 102c-1.

[0042] Furthermore, the clamping member 102 also includes an unlocking rod 102c-4 and a limiting groove 102c-5, wherein the unlocking rod 102c-4 is in a curved shape and is movably arranged in the internal cavity of the clamping plate 102a, one end of which is exposed to the outside of the clamping plate 102a and cooperates with the photovoltaic panel, and the limiting groove 102c-5 is opened on the rod body of the sliding rod 102c-1 and is embedded in one end of the unlocking rod 102c-4.

[0043] Preferably, one end of the unlocking rod 102c-4 that cooperates with the limiting groove 102c-5 is provided with a beveled surface to facilitate the resetting of the clamping plate 102a.

[0044] Next, the rotating member 201 includes a ratchet 201 a and a rotating shaft 201 b , wherein the ratchet 201 a is connected to the side wall of the support plate 101 , and both ends of the rotating shaft 201 b are respectively connected to the support plate 101 and the clamping member 102 .

[0045] Preferably, the shaft 201b rotates on the side wall of the support plate 101. Similarly, the ratchet 201a passes through the shaft 201b and is fixedly set on the side wall of the support plate 101. When the ratchet 202a inside the clamping plate 102a clamps the ratchet 201a, the clamping plate 102a is limited and cannot rotate.

[0046] Furthermore, the locking member 202 includes a ratchet 202a, a connecting rod 202b and a No. 2 spring 202c, wherein one end of the connecting rod 202b passes through the side wall of the slide groove 102c-2 and is arranged inside it, the ratchet 202a is connected to one end of the connecting rod 202b and is movably engaged with the ratchet 201a, and the two ends of the No. 2 spring 202c respectively abut the ratchet 202a and the inner wall of the clamping plate 102a.

[0047] Preferably, a baffle is provided at the end of the slide rod 102c-1. When the clamping is completed, the baffle at the end of the slide rod 102c-1 will press against the side wall of the slide groove 102c-2, thereby pushing the connecting rod 202b passing through it. At this time, the ratchet 202a at the other end of the connecting rod 202b will disengage from the ratchet 201a.

[0048] During use, the operator places the photovoltaic panel in the middle of the clamping plate 102a. When the photovoltaic panel is pressed down, the exposed end of the unlocking lever 102c-4 is pressed. At this time, the beveled surface of the other end of the unlocking lever 102c-4 drops down and disengages from the retaining groove 102c-5. At this time, the compressed No. 1 spring 102c-3 resets and pushes the slide bar 102c-1 to move linearly, so that the clamping block 102b connected to the outside of the slide bar 102c-1 moves toward each other and clamps the photovoltaic panel.

[0049] Then, due to the movement of the sliding rod 102c-1, its end with the baffle pushes the connecting rod 202b, so that the ratchet 202a is disengaged from the ratchet wheel 201a. At this time, the clamping plate 102a can rotate around the rotating shaft 201b, which is convenient for subsequent rotation and cleaning.

[0050] In summary, the clamping member automatically clamps the photovoltaic panel once it is placed in the clamping member. The rotating member and the locking member ensure that the clamping member remains stable and does not rotate when the photovoltaic panel is placed, facilitating installation. Furthermore, once the photovoltaic panel is clamped, the locking member is triggered, unlocking the rotating member, facilitating subsequent rotational cleaning and enhancing the cleaning effect.

[0051] Example 3

[0052] Reference Figure 4 Figure 5 , which is the third embodiment of the present utility model, is based on the first two embodiments, but differs in that a photovoltaic panel cleaning device is provided.

[0053] Specifically, the cleaning assembly 300 includes a power member 301 , a wiping member 302 and a frame member 303 , wherein the power member 301 is connected to the inside of the frame member 303 , and the wiping member 302 is connected to the power member 301 and in contact with the photovoltaic panel.

[0054] Furthermore, the power part 301 includes a motor 301a, a ring 301b, a screw 301c and a synchronous belt 301d, wherein the motor 301a is fixed to the inside of the frame part 303 by bolts, and its output end is connected to the gear 301a-1, and a rack 301b-1 is provided inside the ring 301b, the gear 301a-1 is meshed and connected with the rack 301b-1, and the bottom of the ring 301b is slidably connected to the side wall of the frame part 303, and the screw 301c is set through the inside of the wiper part 302, and its two ends are wrapped and connected with the synchronous belt 301d, and the other end of the synchronous belt 301d is also wrapped and connected with the rotating shaft 201b.

[0055] Preferably, the motor 301a is a reversible motor, which can drive the stainless steel ring 301b to swing back and forth through the engagement of the gear 301a-1 and the rack 301b-1, and the two ends of the screw 301c are rotatably connected to the lower side wall of the support plate 101.

[0056] Furthermore, the wiping member 302 includes a brush 302a, a connecting rod 302b and a screw hole 302c, wherein the hairy surface of the brush 302a contacts the photovoltaic panel, and the other surface is vertically welded to the connecting rod 302b, the screw hole 302c is set through the rod body of the connecting rod 302b, and the screw 301c passes through its interior and engages with it.

[0057] Furthermore, the frame member 303 also includes a flushing pipe 303a, a fan 303b and a universal wheel 303c. The universal wheel 303c is movably connected to the bottom of the frame member 303. The flushing pipe 303a is arranged on one side of the wiping member 302 and is equipped with a water tank and a water pump. The fan 303b is connected to one side of the flushing pipe 303a and cooperates with the photovoltaic panel.

[0058] During use, the operator starts the reversible motor 301a, and the gear 301a-1 and the rack 301b-1 cooperate to drive the ring 301b to swing back and forth. At this time, the brush 302a welded on its upper part wipes the photovoltaic panel back and forth, and the screw hole 302c cooperates with the screw 301c to make the screw 301c rotate back and forth, and drive the synchronous belt 301d at both ends to drive the rotating shaft 201b to rotate, so that the photovoltaic panel can rotate back and forth, which is convenient for wiping the photovoltaic panel more completely. Then, by starting the water tank with a water pump, the flushing pipe 303a sprays water on the surface of the photovoltaic panel, which can be wiped more cleanly. After flushing and wiping are completed, it can be quickly dried under the action of the fan 303b. The entire device is portable because it is equipped with universal wheels 303c.

[0059] In summary, by setting up power parts and wiping parts, the effect of wiping the photovoltaic panels back and forth repeatedly can be achieved. At the same time, by setting up a synchronous belt, the wiping can be achieved while driving the clamping parts to rotate, thereby achieving comprehensive cleaning of the photovoltaic panels. By setting up a frame part, the effect of wiping while also spraying water for cleaning and air drying can be achieved.
