[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] In the related art, the busbar can be connected by a busbar clamp and bolts, where the busbar is clamped by the busbar clamp and the bolts are passed through the busbar clamp to fix the busbar.

[0036] However, after long-term use, there is a risk that the bolts will become loose. For this reason, the staff needs to climb up and down stairs to check each busbar clamp bolt, which results in low inspection efficiency and certain installation risks when climbing.

[0037] To solve the above problems, please refer to Figure 1 to Figure 2 The present application proposes an inspection device 100 for a busbar clamp bolt. In an embodiment of the present application, the inspection device 100 for a busbar clamp bolt includes a main body 10, a clamping portion 30 and a gripping portion 50.

[0038] The main body 10 can be arranged in a tubular or rod-shaped manner, and the material of the main body 10 can be a metal material such as aluminum, copper or stainless steel, so as to have advantages such as better strength. Of course, the material of the main body 10 can also be a plastic material, so as to have advantages such as light weight and convenience for workers to take the inspection device 100 for busbar clamp bolts, and this application does not limit this. The main body 10 includes two connecting ends 15 located at both ends of its length direction.

[0039] The clamping portion 30 can clamp the busbar clamp bolts. The clamping portion 30 can be set in a clamp shape to be similar to the outer surface shape of the busbar clamp bolts. Of course, the clamping portion 30 can also be in the form of two plates combined, and the outer surface of the busbar clamp bolts is clamped by the two plates. This application does not limit this. The clamping portion 30 can be aluminum, copper or stainless steel, etc., to have advantages such as better strength. Of course, the material of the clamping portion 30 can also be plastic material, to have advantages such as light weight to facilitate the staff to take the inspection device 100 of the busbar clamp bolts, etc. This application does not limit this.

[0040] The clamping part 30 is connected to a connection end 15, wherein the clamping part 30 can be an integral structure with the main body 10, for example, the clamping part 30 and the connection end 15 are fixedly connected by welding, etc., so that the connection strength between the clamping part 30 and the main body 10 can be improved. Of course, the clamping part 30 can also be a separate structure from the connection end 15, for example, connected by a snap connection, a threaded connection, etc., so that the corresponding clamping part 30 can be selected according to busbar clamp bolts of different sizes to connect with the main body 10.

[0041] The gripping portion 50 is connected to the other connecting end 15 and includes a first gripping portion 51 and a second gripping portion 53. The first gripping portion 51 can be arranged in a tubular shape or a rod shape, and the material of the first gripping portion 51 can be a metal material such as aluminum, copper or stainless steel, so as to have advantages such as better strength. The first gripping portion 51 is connected to the other connecting end 15 and extends along the length direction of the main body 10. It can be understood that the extension direction of the first gripping portion 51 is consistent with the extension direction of the main body 10.

[0042] The second gripping portion 53 may be arranged in a tubular shape or a rod shape, and the material of the second gripping portion 53 may be a metal material such as aluminum, copper or stainless steel, so as to have advantages such as better strength. The second gripping portion 53 may be connected to the side of the first gripping portion 51 close to the connection end 15. In this way, compared with the second gripping portion 53 being connected to the side of the first gripping portion 51 away from the connection end 15, the setting position of the second gripping portion 53 can reduce the interference with the staff's hand, that is, leaving enough space for the staff to hold the first gripping portion 51. Of course, the second gripping portion 53 may also be connected to the side of the first gripping portion 51 away from the connection end 15, and the embodiment of the present application does not limit this.

[0043] Among them, the extension direction of the second grip portion 53 is set at an angle with the extension direction of the first grip portion 51, that is, the extension direction of the second grip portion 53 will also be set at an angle with the main body 10, for example, at 60 degrees or 90 degrees, etc., that is, the connection between the main body 10, the first grip portion 51 and the second grip portion 53 can roughly form an L-shape, and the present application does not impose any restrictions on this.

[0044] To summarize, the staff can first stand on the ground or floor of the workshop, clamp the busbar clamp bolts by controlling the clamping part 30 of the inspection device 100 for controlling the busbar clamp bolts, and then apply force to the holding part 50 to detect whether the busbar clamp bolts on the ground or floor rotate to determine whether the busbar clamp bolts are loose. In this way, the staff does not need to climb the stairs to check each busbar clamp bolt. They can first check the busbar clamp bolts through the inspection device 100 for the busbar clamp bolts, and then climb the stairs specifically to maintain the busbar clamp bolts that are detected to be loose.

[0045] Furthermore, by providing the first gripping portion 51 and the second gripping portion 53, the extension direction of the first gripping portion 51 is arranged at an angle to the extension direction of the second gripping portion 53. Thus, compared with the related art in which the staff can only hold the gripping portion 50 at a single position to apply force, the arrangement of the embodiment of the present application enables the staff to not only hold the first gripping portion 51 with one hand, but also set the second gripping portion 53 with the other hand, so that the gripping portion 50 provides a larger gripping area for the staff, making it easier for the staff to move, apply force and operate the inspection device 100.

[0046] In actual operation, the staff can stand on the ground or floor, first hold the first grip 51 and the second grip 53 to control the movement of the clamp 30, so that the clamp 30 clamps the busbar clamp bolt, and then the staff can press the first grip 51 and the second grip 53 with both hands to observe whether the busbar clamp bolt will rotate. If the busbar clamp bolt under test does not rotate, the busbar clamp bolt is not loose; if the busbar clamp bolt under test rotates, the busbar clamp bolt is loose, and the staff can climb up the ladder to perform maintenance on the busbar clamp bolt, re-tighten it, and other operations.

[0047] Please refer to Figures 1 to 3 In some embodiments, the first grip portion 51 and the second grip portion 53 are both constructed as a tubular structure. It can be understood that the first grip portion 51 and the second grip portion 53 are hollow on the basis of being constructed as a tubular structure. In this way, the weight of the grip portion 50 can be reduced while ensuring the strength of the grip portion 50.

[0048] Furthermore, the first grip portion 51 and the second grip portion 53 are an integral structure. In this way, the connection strength between the first grip portion 51 and the second grip portion 53 can be improved by setting the integral structure, and the assembly steps of the first grip portion 51 and the second grip portion 53 can be reduced. Of course, in other embodiments, the first grip portion 51 and the second grip portion 53 can also be a split structure, for example, connected by a snap connection, a threaded connection, etc., so that the second grip portion 53 can be replaced or repaired by disassembling the second grip portion 53 as needed.

[0049] Please refer to Figure 1 to Figure 2 In some structural forms, the extension length of the second grip portion 53 is smaller than the extension length of the first grip portion 51. It is understandable that, on the basis that the second grip portion 53 and the first grip portion 51 are both tubular structures, and the diameter of the second grip portion 53 is consistent with the diameter of the first grip portion 51, when the extension length of the second grip portion 53 is smaller than the extension length of the first grip portion 51, it is possible to reduce the weight of the second grip portion 53 while ensuring that the second grip portion 53 provides sufficient gripping space for the staff, thereby reducing the overall weight of the grip portion 50, making it easier for the staff to pick it up. Of course, in other structural forms, the extension length of the second grip portion 53 can also be equal to the extension length of the first grip portion 51, and this application does not limit this.

[0050] Please continue to refer to Figure 1 to Figure 2 In some embodiments, an anti-skid structure 70 is formed on the outer surface of the first gripping portion 51. Thus, based on the provision of the anti-skid structure 70, when the staff member holds the first gripping portion 51, the anti-skid structure 70 can increase the friction with the staff member's hand, especially when the first gripping portion 51 is a tubular structure and the outer surface is relatively smooth, the anti-skid structure 70 can achieve a better anti-skid effect.

[0051] For example, the anti-skid structure 70 can be configured as an anti-skid rib, and the anti-skid rib can be arranged to extend along the circumference of the first gripping portion 51, so that an anti-skid effect can be achieved in the circumferential direction. Furthermore, the anti-skid rib can also be in a broken line shape or a wave shape, so that the anti-skid effect can be further improved. Of course, the anti-skid structure 70 can also be other structural forms such as anti-skid protrusions, which are not limited in the embodiments of the present application.

[0052] Please continue to refer to Figure 1 to Figure 2 In some embodiments, an anti-skid structure 70 is formed on the outer surface of the second gripping portion 53. Thus, based on the provision of the anti-skid structure 70, when the staff member holds the second gripping portion 53, the anti-skid structure 70 can increase the friction with the staff member's hand, especially when the second gripping portion 53 is a tubular structure and the outer surface is relatively smooth, the anti-skid structure 70 can achieve a better anti-skid effect.

[0053] For example, the anti-skid structure 70 can be configured as an anti-skid rib, and the anti-skid rib can be arranged to extend along the circumference of the second gripping portion 53, so that an anti-skid effect can be achieved in the circumferential direction. Furthermore, the anti-skid rib can also be in a broken line shape or a wave shape, so that the anti-skid effect can be further improved. Of course, the anti-skid structure 70 can also be other structural forms such as anti-skid protrusions, which are not limited in the embodiments of the present application.

[0054] Please continue to refer to Figure 1 to Figure 2 In some embodiments, an anti-slip structure 70 is formed on the outer surface of the first grip portion 51, and an anti-slip structure 70 is formed on the outer surface of the second grip portion 53. In this way, when the staff holds the first grip portion 51 and the second grip portion 53 at the same time, both can achieve an anti-slip effect.

[0055] Please refer to Figures 2 to 3 In some embodiments, the clamping portion 30 is formed with a clamping space 31 for clamping the busbar clamp bolt. The inner wall surface of the clamping space 31 is constructed as an inner concave arc surface 311. It can be understood that the outer surface of the busbar clamp bolt is arranged in an annular shape, and in order to enable the clamping portion 30 to clamp the busbar clamp bolt more stably to improve the inspection accuracy in the subsequent inspection step, the inner wall surface of the clamping space 31 is constructed as an inner concave arc surface 311, so that the shape of the inner wall surface of the clamping space 31 can be more matched with the outer surface shape of the busbar clamp bolt, thereby improving the stability of the clamping portion 30 clamping the busbar clamp bolt. In other embodiments, the inner wall surface of the clamping space 31 can also be constructed as a straight surface, which is not limited in the present application.

[0056] Please continue to refer to Figures 1 to 3 , further, the longitudinal cross-sectional area of ​​the clamping space 31 gradually decreases in the direction from the clamping portion 30 to the gripping portion 50. In this way, on the basis of the gradual decrease in the longitudinal cross-sectional area of ​​the clamping space 31, when the busbar clamp bolt gradually extends into the clamping space 31, the distance between the inner wall surface of the clamping space 31 and the outer surface of the busbar clamp bolt will gradually decrease, so that the inner wall surface of the clamping space 31 and the outer surface of the busbar clamp bolt are finally fitted to achieve stable clamping. In other embodiments, the longitudinal cross-sectional area of ​​the clamping space 31 in the direction from the clamping portion 30 to the gripping portion 50 may first increase and then decrease, and the present application does not limit this.

[0057] See also Figure 4In some embodiments, the length of the main body 10 is adjustable. In actual operation, when the staff detects different busbar clamp bolts, there will be a situation where the distance from the staff to the different busbar clamp bolts is inconsistent. Based on this, the embodiment of the present application sets the length of the main body 10 to be adjustable, and the staff can adjust the length of the main body 10 according to the actual distance situation, so that the inspection device 100 for busbar clamp bolts can adapt to more scenarios.

[0058] Please continue reading Figure 4 Furthermore, the main body 10 includes a plurality of sub-main bodies 11 and a connector 13, wherein one end of the sub-main body 11 closest to the clamping portion 30 is formed as a connecting end 15 connected to the clamping portion 30, and one end of the sub-main body 11 closest to the first gripping portion 51 is formed as a connecting end 15 connected to the first gripping portion 51, and two adjacent sub-main bodies 11 are detachably connected via the connector 13.

[0059] It can be understood that the connector 13 may include a connecting piece and at least two fasteners, wherein the connecting piece is provided with two fixing holes for the fasteners to pass through, and a fastener can pass through a corresponding fixing hole and the end thereof abuts against a sub-main body 11. In this way, through the setting of the connector 13, a corresponding number of sub-main bodies 11 can be selected for connection according to needs, so that the length of the main body 10 can be adjusted. For example, when the length of the main body 10 needs to be increased, a larger number of sub-main bodies 11 are selected for combination, and when the length of the main body 10 needs to be reduced, a smaller number of sub-main bodies 11 are selected for combination.

[0060] In other embodiments, the main body 10 may include at least two sub-main bodies 11, wherein the diameter of the sub-main body 11 close to the clamping portion 30 is larger than the diameter of the sub-main body 11 close to the first gripping portion 51, so that the two can be socketed together, and then a slot is provided in the sub-main body 11. After the length of the main body 10 is adjusted, it is fixed by inserting a pin into the slot. In this way, the length of the main body 10 can be adjusted, and the present application does not impose any restrictions on this.
