[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, provides an assembly mechanism, which solves the problem of inconvenient and labor-intensive installation of photovoltaic panels, and includes a main body A, a snap-on assembly 100, and an insertion assembly 200.

[0034] Specifically, the clamping assembly 100 is installed at one end of the outer side of the main body A, and includes a box body 101, an extrusion member 102 and an engagement member 103. The extrusion member 102 is arranged in the inner cavity of the box body 101, and the extrusion member 102 and the engagement member 103 are in contact and connected.

[0035] Furthermore, the insertion component 200 includes an extraction plug 201 and a pressing block 202 , and the pressing block 202 is installed outside the extraction plug 201 .

[0036] When in use, the worker aligns the plug-in unit 201 on one of the photovoltaic panels with the box body 101 and snaps it into place. The pressing block 202 on the plug-in unit 201 pushes the engaging member 103 to rotate. Since the engaging member 103 is in contact and connected with the extruding member 102, the extruding member 102 is rotated and moved, so that the plug-in unit 201 is stuck in the box body 101 and cannot be pulled out, thereby achieving fixation. The worker only needs to align the plug-in unit 201 on the photovoltaic panel with the box body 101 and snap it into place to achieve fixation, which reduces workload and improves installation efficiency.

[0037] In summary, by setting the snap-on component 100 on the outside of the photovoltaic panel, the insertion component 200 is connected, the snap-on component 100 and the insertion component 200 are engaged with each other, and the insertion component 200 is not easy to be pulled out, thereby realizing the assembly of two photovoltaic panels, reducing workload and improving installation efficiency.

[0038] Example 2

[0039] Reference Figure 1 to Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment,

[0040] Specifically, the extrusion member 102 is arranged in the inner cavity of the box body 101, and includes a push plate 102a, a lifting groove 102b, and a lifting block 102c. The push plate 102a is arranged at the bottom end of the inner cavity of the box body 101, and the push plate 102a moves on the bottom side of the box body 101. The lifting groove 102b is opened through the top of the push plate 102a, and the inner side of the lifting groove 102b is in contact with and connected with the lifting block 102c. The lifting block 102c moves up and down inside the lifting groove 102b, and a first spring 102c-1 is installed at the bottom end of the lifting block 102c.

[0041] Furthermore, the extrusion member 102 also includes an unlocking plate 102d, a second spring 102e, and a pressure rod 102f. The unlocking plate 102d is installed at the end of the push plate 102a away from the lifting groove 102b, and moves with the movement of the push plate 102a. The second spring 102e fixes the connection between the box body 101 and the unlocking plate 102d, and the pressure rod 102f is arranged on the outside of the push plate 102a, and the pressure rod 102f is located at one end of the lifting block 102c.

[0042] Furthermore, the engaging member 103 includes a power gear 103a, a rotating shaft 103b, and a track 103c. The power gear 103a is meshed with the lifting block 102c. When the power gear 103a rotates, it drives the lifting block 102c to move horizontally. The bottom end of the rotating shaft 103b is arranged on the inner side of the track 103c, and the rotating shaft 103b is arranged through the inner side of the power gear 103a, that is, the power gear 103a is fixedly connected with the rotating shaft 103b, and the track 103c is installed on the inner side of the box body 101. The power gear 103a can move up and down along the track 103c through the rotating shaft 103b.

[0043] Furthermore, the plug-in assembly 201 includes a push block 201a and a slot 201b. The slot 201b is disposed outside the push block 201a. The push block 201a is in contact with the box body 101. One end of the push block 201a close to the box body 101 is in a frustum shape.

[0044] Furthermore, the pressing block 202 is provided in plurality and all are installed at one end of the outer side of the pushing block 201a. The pressing block 202 is in contact with and connected to the power gear 103a, and the pressing block 202 pushes the power gear 103a to rotate.

[0045] Furthermore, the box body 101 includes a shell 101a, a support plate 101b, and an insertion port 101c. The insertion port 101c is arranged at one end of the shell 101a, and the insertion port 101c is in contact with the push block 201a. The support plate 101b is installed on the inner side of the shell 101a and is arranged at a position close to the insertion port 101c. A squeezing ball 101b-1 is arranged on the bottom side of the support plate 101b, and the squeezing ball 101b-1 is in contact with the card slot 201b.

[0046] Preferably, the curvature of the end surface of the support plate 101b fits the squeezing ball 101b-1, the shape of the slot 201b is complementary to the squeezing ball 101b-1, and one end of the push plate 102a is beveled. When the push plate 102a moves, the beveled cut squeezes the squeezing ball 101b-1 to rise.

[0047] When in use, a worker aligns the push block 201a on one of the photovoltaic panels with the insertion port 101c on the box body 101 and inserts it. A pressure block 202 is installed on the outer side of the top of the push block 201a. Since the pressure block 202 is in contact with the power gear 103a, it pushes the power gear 103a to rotate. The rotation of the power gear 103a drives the lifting block 102c to move horizontally. The lifting block 102c is set on the inner side of the lifting groove 102b, so the movement of the lifting block 102c drives the push plate 102a to move. When the push plate 102a moves, the oblique cut at one end squeezes the squeezing ball 101b-1 to rise. At this time, the squeezing ball 101b-1 rises and is inserted into the slot 201b to limit the push block 201a, so that the push block 201a is initially fixed.

[0048] At the same time, since the top of the push block 201a is in a truncated cone shape, when the pressing block 202 is stuck in the rotating power gear 103a, the truncated cone-shaped push block 201a squeezes the power gear 103a and moves downward at the same time until the push block 201a is stuck. At this time, the power gear 103a squeezes the lifting block 102c and drops to the bottom of the lifting groove 102b. At this time, the power gear 103a is located at the bottom of the lifting groove 102b, and the compressed first spring 102c-1 wants to push the lifting block 102c, but at this time the pressure rod 102f is located at the power gear 103a, blocking the power gear 103a from moving upward; when the push block 201a is about to be pulled out, the squeezing ball 101b-1 is pushed downward, and the pressure block 202 on the push block 201a cannot contact the power gear 103a. At the same time, due to the slope angle of the oblique cut at one end of the push plate 102a and the short distance between the push plate 102a and the top of the box body 101, the squeezing ball 101b-1 cannot push the push plate 102a backward, so the push block 201a cannot be easily pulled out, and the push block 201a is fixed in position again.

[0049] When a worker needs to replace the photovoltaic panel, the second spring 102e is in a stretched state, and the worker only needs to move the unlocking plate 102d. Since the unlocking plate 102d is fixedly connected to the push plate 102a, moving the unlocking plate 102d drives the push plate 102a to move back, reset it, and release the limit on the push block 201a.

[0050] Example 3

[0051] Reference Figure 1 to Figure 7 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a dust cleaning device for photovoltaic panels, which solves the problem of inconvenient operation and installation of existing photovoltaic panels. It includes a rotating component 300 and a cleaning component 400.

[0052] Specifically, the rotating assembly 300 includes a housing 301 and a rotating member 302 . The rotating member 302 is disposed inside the housing 301 , and the bottom end of the rotating member 302 is fixedly mounted on the bottom end of the inner side of the housing 301 .

[0053] Furthermore, the cleaning assembly 400 includes a pushing member 401 and a cleaning member 402 . The pushing member 401 is fixedly connected to one end of the cleaning member 402 , that is, the pushing member 401 moves with the cleaning member 402 .

[0054] Furthermore, the rotating member 302 is arranged on the inner side of the shell 301, including a rotating column 302a, a rotating belt 302b and a motor 302c. The bottom end of the motor 302c is installed on the bottom of the inner side of the shell 301, and the other end of the motor 302c is provided with a rotating column 302a. The motor 302c drives the rotating column 302a to rotate, and the rotating column 302a is in contact and connected with the rotating belt 302b. When the rotating column 302a rotates, the rotating belt 302b moves synchronously, and a protrusion 302b-1 is installed on the outer side of the rotating belt 302b, and a support rod 302b-2 is provided on the top of the protrusion (302b-1). A groove 301a is opened at the top of the shell 301.

[0055] Preferably, the shape of the groove 301a is the same as the moving track of the rotating belt 302b.

[0056] Furthermore, the protrusion 302b-1 is installed on the outside of the rotating belt 302b, that is, when the rotating belt 302b moves, the protrusion 302b-1 also moves therewith, and a support rod 302b-2 is provided on the top of the protrusion 302b-1, that is, the support rod 302b-2 also moves successively, and one end of the support rod 302b-2 away from the protrusion 302b-1 is in contact with and connected to the pushing member 401, and the support rod 302b-2 can drive the pushing member 401 to move.

[0057] Preferably, a block is provided at the top of the support rod 302b-2, so that the contact connection between the support rod 302b-2 and the pushing member 401 is more stable.

[0058] Furthermore, the pushing member 401 includes a moving plate 401a, a connecting rod 401b, and a sliding groove 401c. The moving plate 401a is provided with a sliding groove 401c, and the support rod 302b-2 is in contact with the sliding groove 401c, that is, the sliding groove 401c limits the movement trajectory of the support rod 302b-2 therein, and the connecting rod 401b is installed at the outer bottom end of the moving plate 401a, and a cleaning member 402 is provided at one end of the connecting rod 401b away from the moving plate 401a. The cleaning member 402 is displaced following the movement of the connecting rod 401b, that is, the photovoltaic panel is cleaned.

[0059] Preferably, the sliding groove 401c is configured to be in the shape of a long strip, that is, the movement trajectory of the support rod 302b-2 in the sliding groove 401c is up and down movement.

[0060] Furthermore, the cleaning member 402 includes a cleaning block 402a, a cleaning stick 402b and a support rod 402c. The cleaning block 402a is installed on one end of the connecting rod 401b away from the movable plate 401a. The connecting rod 401b drives the cleaning block 402a to move. The axis of the cleaning stick 402b is located on the inner side of the cleaning block 402a. The support rod 402c movably connects the cleaning stick 402b and the cleaning block 402a, that is, the support rod 402c is fixedly connected to the cleaning block 402a, and the cleaning stick 402b is movably connected to the support rod 402c, and bristles 402b-1 are evenly arranged on the outer side of the cleaning stick 402b. When the cleaning stick 402b rotates, the bristles 402b-1 can rotate accordingly, and then the photovoltaic panel is cleaned by the bristles 402b-1.

[0061] Furthermore, the number of motors 302c is set to two, the rotating column 302a and the motor 302c are set correspondingly, and both ends of the rotating belt 302b are in contact with the rotating column 302a. When the motor 302c drives the rotating column 302a to rotate, the rotating belt 302b moves accordingly.

[0062] During use, the staff drives the motor 302c, and the motor 302c drives the rotating column 302a to rotate. Since the rotating column 302a is in contact and connected with the rotating belt 302b, when the rotating column 302a rotates, the rotating belt 302b also moves synchronously, and the protrusion 302b-1 on the outside of the rotating belt 302b also moves with it. Since the support rod 302b-2 is installed on the protrusion 302b-1, the other end of the support rod 302b-2 drives the moving plate 401a to move.

[0063] When the support rod 302b-2 moves with the protrusion 302b-1, the support rod 302b-2 will move in the sliding groove 401c. When the support rod 302b-2 moves to the rotating column 302a, the support rod 302b-2 moves from the upper end to the lower end of the sliding groove 401c. During this process, the movable plate 401a will have a small displacement, and the support rod 302b-2 continues to move, driving the movable plate 401a to move in the opposite direction. In this way, the cleaning block 402a can move back and forth, which can more comprehensively clean the photovoltaic panel and improve the power generation efficiency.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
