[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "top" and "bottom", generally refer to the top and bottom of the device in actual use or working state, specifically the direction of the drawing in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0022] See also Figure 1 , Figure 2 As shown, an embodiment of the utility model provides a wiring device for photovoltaic electrical detection, including a box body 1, a wiring port 2 and a cover plate 3 adapted to the wiring port 2 are provided on the top of the box body 1, and the wiring can be carried out from the wiring port 2 by opening the cover plate 3. After the wiring is completed, the internal wiring of the box body 1 can be protected by re-covering the cover plate 3. Specifically, the embodiment of the utility model has horizontally arranged slide grooves 4 on both sides of the wiring port 2, one end of the slide groove 4 is open, and the two sides of the cover plate 3 can be slidably inserted into the corresponding slide grooves 4, so that the cover plate 3 can slide along the slide groove 4 relative to the box body 1 to open or close the wiring port 2. Furthermore, a handle 5 can be provided on the cover plate 3 to facilitate pulling the cover plate 3. An observation glass 6 can also be embedded on the cover plate 3 to observe the wiring situation inside the box body 1.

[0023] A plurality of pairs of threading holes 7 are arranged on both sides of the box body 1. When wiring, the wires to be connected can be respectively inserted into the box body 1 from the corresponding threading holes 7 on both sides, which is convenient for wire management. An adjusting ring 8 is coaxially fixed to the outer end of the threading hole 7 (i.e., the end facing the outer side of the box body 1). A threaded tube 9 is connected through the outer end of the adjusting ring 8. The outer peripheral wall of the threaded tube 9 is threadedly connected to the inner peripheral wall of the adjusting ring 8. A plurality of deformation seams 10 are arranged at intervals along the circumference of the outer end of the threaded tube 9. The length direction of the deformation seam 10 is consistent with the length direction of the threaded tube 9. The diameter of the outer end of the threaded tube 9 gradually decreases toward the inner end. When the threaded tube 9 is rotated to move the threaded tube 9 into the adjusting ring 8, the outer end of the threaded tube 9 can be squeezed inward by the adjusting ring 8, thereby clamping and fixing the wires passing through. When wiring, the wires can be passed through the threaded tube 9 into the box body 1, and the threaded tube 9 can be rotated according to the diameter of the wires to adjust the diameter of the outer end of the threaded tube 9, so as to clamp the wires so that the wires can remain relatively fixed, which not only improves the stability of the internal wiring, but also ensures the sealing of the threading point.

[0024] Further, such as Figure 2 , Figure 3 As shown, in the embodiment of the utility model, an arc-shaped support plate 11 is provided between each pair of threading holes 7, and a damping expansion joint 12 is connected between the bottom of the arc-shaped support plate 11 and the inner bottom wall of the box body 1. The arc-shaped support plate 11 can support and dampen the wiring inside the box body 1, thereby reducing the probability of loose wiring.

[0025] Furthermore, in the embodiment of the utility model, the cover plate 3 is detachably provided with a cover such as Figure 4 The protective cover 13 shown can enhance the protection of the internal wiring of the box body 1; a sealing gasket 14 is provided between the protective cover 13 and the cover plate 3, which can improve the sealing of the box body 1 and prevent concrete and the like from entering the box body 1 from the top and causing damage to the wires.

[0026] In addition, in order to facilitate carrying or transporting, the embodiment of the utility model is also equipped with a portable handle 15 on the box body 1, and the two ends of the portable handle 15 are rotatably connected to the two sides of the box body 1, so that the portable handle 15 can be rotated relative to the box body 1, which is convenient for use. Considering that when the box body 1 is lifted by the portable handle 15, the box body 1 usually shakes back and forth, causing the box body 1 to easily collide with the front object, therefore, an alloy protective plate 16 can be set on the outer side wall of the box body 1 (especially the outer side wall of the front side), and the protective plate 16 is used to protect the box body 1 from collision.
