Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and in particular to a clamping device, a photovoltaic bracket and a photovoltaic system. Background Art

[0002] Photovoltaic modules are generally installed on roofs, hillsides or fields through photovoltaic brackets. The photovoltaic bracket generally includes a main shaft, purlins arranged on the main shaft, and a clamping piece. When the photovoltaic module is installed on the photovoltaic bracket, the edge of the photovoltaic module overlaps the purlin. When multiple photovoltaic modules are installed on the photovoltaic bracket, the adjacent edges of two photovoltaic modules overlap side by side on the same purlin, and then the clamping piece clamps the edge of the photovoltaic module between the clamping piece and the purlin, thereby realizing the installation and fixation of the photovoltaic module on the photovoltaic bracket.

[0003] It can be seen that in the related art, the photovoltaic bracket generally fixes the photovoltaic module by contacting the purlin with the lower surface of the photovoltaic module, and the clamping member contacts the upper surface of the photovoltaic module, thereby clamping the photovoltaic module. When the photovoltaic module is impacted by an external load, the photovoltaic module is prone to slide in a direction parallel to the surface of the photovoltaic module or along the main axis of the photovoltaic bracket, and the photovoltaic bracket has poor stability in installing the photovoltaic module.

[0023] In some embodiments, the first side wall and the second side wall are both formed with a slide groove, and one end of the connecting member cooperates with the slide groove of the first side wall, and the other end cooperates with the slide groove of the second side wall.

[0024] In some embodiments, the connecting member is provided with an adjustment threaded hole;

[0025] The clamping device also includes:

[0026] An adjusting rod passes through the bottom wall of the installation slot and cooperates with the adjusting threaded hole, and is used to drive the connecting member to move in a direction away from or close to the bottom wall of the installation slot.

[0051] See also Figure 1 , Figure 6 and Figure 7 The present application provides a clamping device 100 that can be used in a photovoltaic bracket to clamp adjacent edges of two adjacent photovoltaic modules 400, but is not limited thereto.

[0052] Please also read Figure 2 The clamping device 100 provided in one embodiment of the present application includes a base 10, a clamping assembly 20 and a connecting member 30. The base 10 is formed with a mounting groove 10a. The mounting groove 10a has a first side wall 11 and a second side wall 12 opposite to each other, and the first side wall 11 and the second side wall 12 are both formed with a guide surface 13. The clamping assembly 20 includes a first clamping block 21 and a second clamping block 22. The first clamping block 21 is arranged to fit the guide surface 13 of the first side wall 11; the second clamping block 22 is arranged to fit the guide surface 13 of the second side wall 12. The guide surface 13 is used to guide the first clamping block 21 and the second clamping block 22 to move relative to or opposite to each other. One end of the connecting member 30 is slidably connected to the first clamping block 21, and the other end is slidably connected to the second clamping block 22. The connecting member 30 is movably arranged in the mounting groove 10a along a direction perpendicular to the bottom surface of the mounting groove 10a, and is used to drive the first clamping block 21 and the second clamping block 22 to move along the guide surface 13.

[0053] The embodiment of the present application is described by taking the bottom surface of the mounting groove 10a of the clamping device 100 as an example when it is in normal use and is horizontal, and the direction perpendicular to the bottom surface of the mounting groove 10a is the vertical direction. The connecting member 30 is movably arranged in the mounting groove 10a along the vertical direction, that is, when the connecting member 30 moves along the vertical direction, it pushes the first clamping block 21 and the second clamping block 22 to move along the corresponding guide surface 13 respectively, and in the process of moving along the guide surface 13, it simultaneously moves in the relative or opposite directions, so that the photovoltaic module 400 can be clamped or loosened, such as Figure 3 and Figure 4 .

[0054] The base 10 is formed with a mounting groove 10a. The mounting groove 10a may be an open through groove formed on the base 10, and the cross section of the open through groove may be an isosceles trapezoid or an isosceles triangle, but is not limited thereto. In the embodiment of the present application, the cross section of the mounting groove 10a is an isosceles trapezoid as an example for explanation, and it can be understood that the mounting groove 10a has a bottom wall in addition to the first side wall 11 and the second side wall 12 facing each other. The first side wall 11 and the second side wall 12 form a guide surface 13 on one side surface facing the inside of the mounting groove 10a, and the bottom wall forms a bottom surface on one side surface facing the inside of the mounting groove 10a. The guide surface 13 may be an inclined surface. In order to facilitate the first clamping block 21 and the second clamping block 22 to cooperate with the component to be clamped, the guide surface 13 on the first side wall 11 and the guide surface 13 on the second side wall 12 are away from each other in the direction from the bottom surface of the mounting groove 10a to the opening of the mounting groove 10a.

[0055] The clamping assembly 20 includes a first clamping block 21 and a second clamping block 22, and the first clamping block 21 and the second clamping block 22 are relatively moved to clamp the part to be clamped. The first clamping block 21 and the second clamping block 22 may both have a fitting surface and a clamping surface. The first clamping block 21 is arranged to fit the guide surface 13 of the first side wall 11, that is, the fitting surface of the first clamping block 21 is fitted to the guide surface 13 of the first side wall 11, and can move relatively, so that the first clamping block 21 can move along the guide surface 13. Correspondingly, the second clamping block 22 is arranged to fit the guide surface 13 of the second side wall 12, that is, the fitting surface of the second clamping block 22 is fitted to the guide surface 13 of the second side wall 12, and can move relatively. The guide surface 13 of the first side wall 11 and the guide surface 13 of the second side wall 12 are arranged opposite to each other. After the first clamping block 21 and the second clamping block 22 are respectively fitted with their corresponding guide surfaces 13, the clamping surface of the first clamping block 21 and the clamping surface of the second clamping block 22 are arranged opposite to each other. When the first clamping block 21 and the second clamping block 22 move relative to each other along the corresponding guide surfaces 13, they clamp the part to be clamped; when the first clamping block 21 and the second clamping block 22 move away from each other along the corresponding guide surfaces 13, they release the part to be clamped.

[0056] The connecting member 30 is movably disposed in the mounting groove 10a along a direction perpendicular to the bottom surface of the mounting groove 10a. Figure 2 As shown, in some embodiments, the first side wall 11 and the second side wall 12 are further formed with a slide groove 14, one end of the connector 30 cooperates with the slide groove 14 of the first side wall 11, and the other end cooperates with the slide groove 14 of the second side wall 12, so that the connector 30 can move vertically in the slide groove 14. The slide groove 14 can not only accommodate the end of the connector 30, but also provide guidance for the movement of the connector 30, thereby improving the stability of the movement of the connector 30.

[0057] The two ends of the connecting member 30 are respectively connected to the first clamping block 21 and the second clamping block 22 by sliding. When the connecting member 30 moves in a direction perpendicular to the bottom surface of the installation groove 10a, the first clamping block 21 and the second clamping block 22 can be pushed to move along the corresponding guide surface 13 at the same time. It should be noted that in the process of the connecting member 30 moving in the vertical direction, in order to prevent the first clamping block 21 and the second clamping block 22 from being separated from the corresponding guide surface 13, a limiting structure can be provided. The limiting structure can be a limiting groove and a limiting protrusion that cooperate with each other. For example, taking the first clamping block 21 and the guide surface 13 of the first side wall 11 as an example, one of the first clamping block and the first side wall 11 is provided with a T-shaped groove, and the other is provided with a T-shaped protrusion that cooperates with the T-shaped groove; the limiting structure can also be an elastic component, which always squeezes the first clamping block 21 to fit with the guide surface 13 during the movement of the first clamping block 21 along the guide surface 13. The specific implementation form of the limiting structure is not limited to this.

[0058] like Figure 2 As shown, in some embodiments, the connecting member 30 may include an intermediate connecting portion 31 and a slide rail portion 32 distributed on opposite sides of the intermediate connecting portion 31, and the slide rail portion 32 is slidably matched with the first clamping block 21 and the second clamping block 22. The embodiment of the present application does not limit the specific shape of the slide rail portion 32 on the connecting member 30. For example, the cross-sectional shape of the slide rail portion 32 may be T-shaped, trapezoidal or triangular. In the embodiment of the present application, the cross-sectional shape of the slide rail portion 32 is T-shaped as an example for explanation. Correspondingly, a T-shaped slot is provided on the first clamping block 21 and the second clamping block 22.

[0059] To ensure that the first clamping block 22 and the second clamping block 22 can fit the guide surface 13, in some embodiments, as Figure 1 and Figure 2 As shown, the clamping device 100 may also include a first elastic member 41. The first elastic member 41 is connected between the first clamping block 21 and the intermediate connecting portion 31 and between the second clamping block 22 and the intermediate connecting portion 31, and the first elastic member 41 is in a compressed state. The first elastic member 41 may be a spring or an elastic rubber member, but is not limited thereto. In the embodiment of the present application, the first elastic member 41 is taken as an example for explanation. By connecting the first elastic member 41 in a compressed state between the first clamping block 21 and the intermediate connecting portion 31 and between the second clamping block 22 and the intermediate connecting portion 31, the first clamping block 21 and the second clamping block 22 can be tightly fitted with the corresponding guide surface 13 under the extrusion of the first elastic member 41. In addition, when it is necessary to release the clamping of the photovoltaic assembly 400 by the clamping assembly 20, after releasing the fixation of the connecting member 30, the first clamping block 21 and the second clamping block 22 can move in opposite directions under the action of the first elastic member 41, and the photovoltaic assembly 400 is automatically released.

[0060] The number of first elastic members 41 used in the clamping device 100 is at least two. In some embodiments, the number of first elastic members 41 can also be four, and one first elastic member 41 is arranged on both sides of the slide rail portion 32 on each side of the middle connecting portion 31 to improve the overall working stability of the clamping device 100.

[0061] Of course, if Figure 1 and Figure 2 As shown, in some embodiments, the clamping device 100 may further include a first guide rod 51. At least one first guide rod 51 is provided on both sides of the intermediate connecting portion 31. One end of the first guide rod 51 is fixedly connected to the intermediate connecting portion 31, and the other end is slidably connected to the first clamping block 21 or the second clamping block 22; or one end of the first guide rod 51 is slidably connected to the intermediate connecting portion 31, and the other end is fixedly connected to the first clamping block 21 or the second clamping block 22. In the embodiment of the present application, the first guide rod 51 is fixedly connected to the middle connection part 31 and is slidably connected to the clamping assembly 20 as an example for explanation, wherein the slidably connected guide rod and the clamping assembly 20 refers to the guide rod between the middle connection part 31 and the first clamping block 21 being slidably connected to the first clamping block 21 in the clamping assembly 20, and the guide rod between the middle connection part 31 and the second clamping block 22 being slidably connected to the second clamping block 22 in the clamping assembly 20, and correspondingly, the first clamping block 21 and the second clamping block 22 are formed with a first guide hole 23 that cooperates with the first guide rod 51. By providing the first guide rod 51, further guidance can be provided for the relative or opposite movement of the first clamping block 21 and the second clamping block 22.

[0062] In some embodiments, when the clamping device 100 includes both the first elastic member 41 and the first guide rod 51, the first guide rod 51 may be inserted into the first elastic member 41. It is understood that the number of first guide rods 51 in the clamping device 100 corresponds to the number of first elastic members 41. By inserting the first guide rod 51 into the first elastic member 41, the first elastic member 41 may be prevented from being offset during movement.

[0063] like Figure 1 and Figure 2As shown, in some embodiments, the clamping device 100 may further include a second elastic member 42. The second elastic member 42 is connected between the connecting member 30 and the bottom surface of the mounting groove 10a, and when the clamping assembly 20 clamps the part to be clamped, the second elastic member 42 is in a compressed state. The connecting member 30 moves toward the bottom surface of the mounting groove 10a, driving the first clamping block 21 and the second clamping block 22 to move relative to each other, so that the part to be clamped can be clamped. When the clamping assembly 20 clamps the part to be clamped, the second elastic member 42 is in a compressed state. When the part to be clamped needs to be released, after the force that fixes the position of the connecting member 30 relative to the bottom surface of the mounting groove 10a is released, the second elastic member 42 can push the connecting member 30 to move upward, so that the first clamping block 21 and the second clamping block 22 move in opposite directions, avoiding that the first clamping block 21 and the second clamping block 22 still maintain the clamping state of the part to be clamped under the action of gravity. Of course, the second elastic member 42 can also be a spring or an elastic rubber member, but is not limited to this. There is at least one second elastic member 42 disposed between the connecting member 30 and the bottom surface of the mounting groove 10a. In some embodiments, to ensure that the connecting member 30 can move stably under the extrusion of the second elastic member 42, two second elastic members 42 can be disposed, and the two second elastic members 42 are symmetrically disposed on the connecting member 30.

[0064] Of course, if Figure 2 As shown, in some embodiments, the clamping device 100 may further include a second guide rod 52. At least one second guide rod 52 is provided. One end of the second guide rod 52 is fixedly connected to the base 10, and the other end is slidably connected to the connecting member 30; or, one end of the second guide rod 52 is slidably connected to the base 10, and the other end is fixedly connected to the connecting member 30. In the embodiment of the present application, an example is taken for explanation that one end of the second guide rod 52 is fixedly connected to the base 10, and the other end is slidably connected to the connecting member 30. Correspondingly, a second guide hole 33 cooperating with the second guide rod 52 is formed on the connecting member 30. By providing the second guide rod 52, it is possible to provide guidance for the movement of the connecting member 30 in the direction along the bottom surface of the vertical mounting groove 10a, and at the same time, the second guide rod 52 can be restricted from rotating around the rotation axis of the bottom surface of the vertical mounting groove 10a.

[0065] In some embodiments, when the clamping device 100 includes both the second elastic member 42 and the second guide rod 52, the second guide rod 52 can be inserted into the second elastic member 42. It can be understood that the number of second guide rods 52 provided corresponds to the number of second elastic members 42 provided. By inserting the second guide rod 52 into the second elastic member 42, the second elastic member 42 can be prevented from being offset during movement.

[0066] The clamping device 100 provided in the above-mentioned embodiment of the present application, when moved toward the bottom surface of the mounting groove 10a through the connecting member 30 so that the first clamping block 21 and the second clamping block 22 clamp the part to be clamped, it can be understood that when using the clamping device 100 for clamping, a component is required to push the connecting member 30 to move and enable the clamping device 100 to maintain a clamped state.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, an adjusting threaded hole 34 may be provided on the connecting member 30. When using the clamping device 100, a bolt that cooperates with the adjusting threaded hole 34 may be used to drive the connecting member 30 to move by rotating the bolt. Of course, in some embodiments, the clamping device 100 may also include an adjusting rod 60, which penetrates the bottom wall of the mounting groove 10a and cooperates with the adjusting threaded hole 34 to drive the connecting member 30 to move in a direction away from or close to the bottom wall of the mounting groove 10a. The adjusting rod 60 may have a head structure, which abuts against a side surface of the bottom wall of the mounting groove 10a facing away from the inside of the mounting groove 10a.

[0068] like Figure 5 and Figure 6 As shown, in some embodiments, the present application also provides a photovoltaic bracket. The photovoltaic bracket includes a main shaft 300, a purlin 200 and a clamping device 100 in any of the above embodiments. The purlin 200 is arranged on the main shaft 300, the clamping device 100 is arranged on the side of the purlin 200 that is used to face away from the photovoltaic assembly 400, and the first clamping block 21 and the second clamping block 22 in the clamping device 100 are distributed on opposite sides of the purlin 200, so that when the adjacent edges of two adjacent photovoltaic assemblies 400 are overlapped on the same purlin 200, the first clamping block 21 and the second clamping block 22 on both sides of the purlin 200 can clamp the lower part of the two adjacent edges of the two photovoltaic assemblies 400. It should be noted that the embodiment of the present application does not impose any specific restrictions on the connection method between the clamping device 100 and the purlin 200. For example, a threaded hole may be provided on the base 10 in the clamping device 100, and the clamping device 100 and the purlin 200 may be connected by bolts.

[0069] like Figure 6 and Figure 7 As shown, in some embodiments, the present application further provides a photovoltaic system. The photovoltaic system includes at least two groups of photovoltaic components 400 and the photovoltaic bracket in the above embodiment. The adjacent two side edges of the two groups of photovoltaic components 400 are overlapped on the same purlin 200, and the clamping device 100 clamps the adjacent two side edges of the two groups of photovoltaic components 400.
