Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation, and particularly relates to a protection structure for a busbar box. Background Art

[0002] A busbar box, also known as a combination box or a busbar box, is a device used in a solar photovoltaic power generation system. Its main function is to collect the output currents of multiple photovoltaic modules or photovoltaic strings together and connect them to an inverter or other power transmission facilities through a common outlet. When using the busbar box, it is necessary to install the busbar box on a protection structure for the busbar box, so that the protection structure for the busbar box protects the busbar box.

[0003] For the existing protection structure of the busbar box, different support rods are connected and fixed by bolts, so that different support rods are combined into a support frame, and then the busbar box is installed and fixed on the support frame by bolts, so that the support frame protects the busbar box during use. However, in the actual use process, since the busbar box is widely used in various scales of photovoltaic power generation systems, from small household roof systems to large-scale ground power station projects, when installing and protecting the busbar box, considering the environmental factors of the installation of the support frame, it is necessary for personnel to painstakingly assemble support frames of different specifications, and this process is relatively troublesome and time-consuming.

However, the protection scope of the present utility model is not limited to the following embodiments. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0021] Such as Figure 1 、 2As shown in the figure, it includes a first support 101. On the left and right sides of the first support 101, there are sliding seats 102 slidably arranged. On the lower surfaces of the sliding seats 102, there are bases 103. On the rear side of the upper surface of the first support 101, there are two symmetrically distributed sliding cylinders 105 on the left and right. Inside the sliding cylinders 105, there are sliding columns 106 slidably arranged. Between the tops of the sliding columns 106, there is a second support 107. On the left and right sides of the second support 107, there are sliding seats 108 slidably arranged. Between the sliding seat 102 and the vertically adjacent sliding seat 108, there is an H-shaped frame 109 slidably arranged. On the side of the sliding seat 102 and the sliding seat 108 close to the H-shaped frame 109, there are two symmetrically distributed mounting plates 110 front and rear. On the upper surfaces of the mounting plates 110, there are mounting grooves. On the first support 101, there is also a first adjusting module for adjusting the distance between the H-shaped frames 109. On the H-shaped frame 109, there is also a second adjusting module for adjusting the distance between the first support 101 and the second support 107.

[0022] As Figure 2 , 3 shown, the first adjusting module includes guide rails 201 uniformly arranged inside the first support 101. Between the guide rails 201, there are two symmetrically distributed sliding seats 202 slidably arranged. On the left and right sides of the sliding seats 202, there are two symmetrically distributed connecting rods 203 up and down rotatably arranged. On one end of the sliding seat 102 close to the vertical center of the first support 101, there are two symmetrically distributed rotating seats 204 front and rear. The ends of the connecting rods 203 far from the sliding seats 202 are respectively rotatably connected to the adjacent rotating seats 204. On the first support 101, there is also a first driving unit for driving the sliding seat 202 to move; the first driving unit includes a two-way screw rod 205 rotatably arranged in the middle of the first support 101. The two sliding seats 202 are both threadedly connected to the two-way screw rod 205. The front end of the two-way screw rod 205 is provided with an internal hexagonal head 206.

[0023] As Figure 2 , 4 shown, the second adjusting module includes a guiding chute 301 opened in the middle of the H-shaped frame 109. Inside the guiding chute 301, there are two symmetrically distributed sliders 302 slidably arranged. On the upper and lower sides of the sliders 302, there are connecting rods 304 rotatably arranged. On the side of the sliding seat 102 and the sliding seat 108 close to the H-shaped frame 109, there are rotating plates 303. The ends of the connecting rods 304 far from the sliders 302 are respectively rotatably connected to the adjacent rotating plates 303. On the H-shaped frame 109, there is also a second driving unit for moving the sliders 302; the second driving unit includes a two-way screw rod 305 rotatably arranged in the middle of the H-shaped frame 109. The front ends of the two-way screw rod 305 are both provided with knobs 306.

[0024] As Figure 1 , 2As shown, two fixing plates 104 which are symmetrically distributed left and right are provided on both the front and rear sides of the base 103.

[0025] During use, the operator turns the hexagon socket head 206 with an external tool, causing the hexagon socket head 206 to drive the two-way lead screw 205 connected thereto to rotate. Then, due to the threaded relationship between the two-way lead screw 205 and the sliding seat 202, the sliding seats 202 on the front and rear sides move towards or away from each other, causing the two sliding seats 202 to slide between the guide rails 201. During the movement of the sliding seat 202, rotation occurs between the sliding seat 202 and the connecting rod 203, and rotation occurs between the connecting rod 203 and the rotating seat 204. Thus, the sliding seat 202 drives the sliding seats 102 on the left and right sides to move towards or away from each other through the connecting rod 203. At this time, the sliding seat 108 moves towards or away from each other under the action of the sliding seat 102, driving the H-shaped frames 109 on the left and right sides to move towards or away from each other, adjusting the distance between the H-shaped frames 109 on the left and right sides so that the distance between the H-shaped frames 109 adapts to the installation environment; by turning the knobs 306 on the left and right sides, the knobs 306 drive the two-way lead screw 305 connected thereto to rotate. Then, due to the threaded relationship between the two-way lead screw 305 and the slider 302, the sliders 302 on the front and rear sides move towards or away from each other. During the movement of the slider 302, rotation occurs between the slider 302 and the connecting rod 304, and rotation occurs between the connecting rod 304 and the rotating plate 303. Thus, the slider 302 drives the H-shaped frame 109 to slide between the support 101 and the support 107 through the connecting rod 304, further adjusting the distance between the support 101 and the support 107 so that the distance between the support 101 and the support 107 can quickly adapt to the vertical height of the installation environment. By freely adjusting the distance between the sliding seats 102, the distance between the sliding seats 108, and the distance between the sliding seat 102 and the sliding seat 108 in cooperation, the protective support frame composed of the support 101, the sliding seat 102, the H-shaped frame 109, the sliding seat 108, and the support 107 can freely extend and contract, and can freely adapt to the installation environment to protect the busbar trunking.

[0026] According to another embodiment of the present invention, as Figure 1 、 2 shown, rubber pads are provided on the sides of the mounting plate 110 close to the H-shaped frame 109. When the busbar trunking is installed between the mounting plates 110 by bolts, the rubber pads provided on the mounting plate 110 can make the mounting plate 110 in flexible contact with the busbar trunking, thereby effectively avoiding damage to the outer shell of the busbar trunking due to excessive tightening of the bolts during installation.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
