[0027] Since the pressing edge 10 will press the photovoltaic module 20 from the top during clamping of the component, if hard contact is adopted, on the one hand, point contact may be caused, the contact area is reduced, and damage to the two is easy, and on the other hand, under the condition of shaking, vibration is easy to cause damage to the component and the pressing block, in order to solve the above technical problems, in an embodiment, the stepless adjustable photovoltaic module 20 fixing side pressing block further comprises a buffer layer 14 arranged at the bottom of the arc-shaped pressing head, and the buffer layer 14 is bonded with the arc-shaped pressing head through a bonding layer or is clamped through a clamping piece.

[0028] By arranging the buffer layer 14 at the bottom of the arc-shaped pressing head, soft contact of the pressing head and the component is realized, the contact area is increased, damage caused in the process of installation and the like is reduced, and at the same time, the arrangement of the buffer layer 14 can buffer in the process of vibration and the like, reduce collision caused by hard contact, and improve the safety and service life in use.

[0037] The base 30 is arranged on the cross beam 40. If the base 30 is smooth, it will not be easy to fix. In order to improve the fixing efficiency, in one embodiment, the steplessly adjustable photovoltaic module 20 fixing side pressing block further comprises an anti-slip tooth structure 34 arranged at the bottom of the base 30.

[0038] By arranging the anti-slip tooth structure 34, the friction between the base 30 and the cross beam 40 is improved, and the installation reliability is improved.

[0039] The shape, size, and the like of the anti-skid tooth structure 34 are not limited in the present application, including but not limited to the above-mentioned size and anti-skid structure.

[0042] The forming method of the trapezoidal reinforcing cavity 33 is not limited in the present application. In an embodiment, the trapezoidal reinforcing cavity 33 includes a trapezoidal long side, a trapezoidal short side, a trapezoidal bottom side, and a trapezoidal oblique side. The trapezoidal long side and the trapezoidal short side are arranged vertically and parallel to each other. The trapezoidal short side is arranged on the side of the base 30 close to the photovoltaic assembly 20. The trapezoidal long side is arranged on the side of the base 30 away from the photovoltaic assembly 20. The trapezoidal bottom side is arranged on the side of the base 30 close to the bottom of the base 30.

[0043] The connection method and size of the trapezoidal long side, the trapezoidal short side, the trapezoidal bottom side, and the trapezoidal oblique side are not limited in the present application, including but not limited to bolt connection, welding, clamping, and the like.

[0046] In one embodiment, the stepless adjustable photovoltaic module fixing side pressing block is composed of the pressing edge 10 and the base 30. The pressing edge 10 is composed of an arc-shaped pressing head, a rubber pad, an arc-shaped arch back 12, and a plug-in shaft seat groove 13. The plug-in shaft seat groove 13 is used to be plugged and connected with the round head bearing 32 of the base 30. The inner groove is set to be circular, which can make the plug-in adjustable pressing block-pressing edge 10 rotate around the round head bearing 32, and is the key function to realize stepless adjustment. The arc-shaped arch back 12 is set to be an arc-shaped arch upward, which is used to enhance the overall bending resistance of the pressing edge 10 through the arching effect. The arc-shaped pressing head is set to be arc-shaped, which is used to make the contact area of the pressing edge 10 with the module equal regardless of the angle adjustment of the pressing edge 10, so that the stress is more uniform, and the installation stability of the adjustable pressing block is increased. The arc-shaped pressing head is provided with a rubber pad, which is used to make the contact of the arc-shaped pressing head with the photovoltaic module 20 flexible and transition, so that the force transmission is more uniform, and stress concentration does not occur.

[0047] The base 30 is composed of a base body 31, a round head bearing 32, a trapezoidal reinforcing cavity, and an anti-skid tooth structure 34. The round head bearing 32 is used to be plugged with the plug-in shaft seat groove 13 of the pressing edge 10. The bearing is set to be a round head, which can make the plug-in adjustable pressing block-pressing edge 10 rotate around the round head bearing 32, and is the key function to realize stepless adjustment. The trapezoidal reinforcing cavity is composed of a trapezoidal long side, a short side, a bottom side, and an inclined side, which is used to make the structure of the adjustable pressing block-base 30 more stable. Without the reinforcing inclined side, the structure is more prone to instability under stress. The reinforcing long side is used to support the adjustable pressing block-pressing edge 10 and receive the force transmitted from above. The reinforcing short side is used to be in close contact with the photovoltaic module 20, which increases the overall stability of the pressing block. The reinforcing bottom side is used to increase the contact surface between the stepless adjustable photovoltaic module fixing side pressing block and the cross beam 40, which increases the overall stability. At the same time, the anti-skid tooth is provided above, which improves the friction between the adjustable side pressing block and the cross beam 40, so that the pressing block is less likely to loosen and slip under stress.

[0048] The cross beam 40 is fixed on the cross beam 40 through a bolt and a clamping nut. The limiting clamping groove of the clamping nut and the rotary hem of the cross beam 40 are clamped with each other, which can prevent the clamping nut from rotating during bolt installation. Only the inner hexagonal bolt needs to be rotated to complete the installation.

[0049] In conclusion, the side pressing block for fixing photovoltaic module with stepless adjustment provided by the embodiments of the utility model, through setting the pressing edge on the top of the base, setting the round head bearing at one end, rotating connection with the plug-in shaft seat slot corresponding to the pressing edge, clamping the photovoltaic module through the base of the side part, the crossbeam of the bottom and the pressing edge of the top, finally, fixing the photovoltaic module through the connecting bolt in turn through the pressing edge, the base and the crossbeam, since the round head bearing is rotatingly connected with the plug-in shaft seat slot, only the height of the photovoltaic module clamped by the pressing edge needs to be rotated, so the fixing of the photovoltaic module with different thickness can be realized, stepless adjustment is realized, the applicability is stronger, the problem that the pressing block materials are easily confused in the process of the application of the modules with different heights in large quantities is effectively solved, the problems of the error of distinguishing in storage and transportation and the error of installation on site are avoided.
