Description

Technical Field

[0001] The utility model relates to the technical field of safety protection of distribution boxes, and particularly relates to a safety protection structure for a distribution box in tunnel construction. Background Technique

[0002] In the field of tunnel construction, as the core equipment for power distribution and control, the safe and stable operation of the distribution box is directly related to the smooth progress of the entire construction process and the safety of the operators. The tunnel environment is complex and changeable, with limited space and often accompanied by adverse factors such as humidity and dust, which pose extremely high requirements for the distribution box and its protection structure.

[0003] Most of the traditional protection structures for distribution boxes are of fixed design, that is, customized installation is carried out according to the size of a specific model of distribution box. This method has significant limitations. Since different sizes of distribution boxes require different specifications of protection structures, it increases the procurement cost and maintenance difficulty. In addition, the distribution boxes in tunnel construction often need to be placed in a limited space, and the traditional protection structure is particularly clumsy and inconvenient when facing size changes or space limitations, and it is difficult to meet the flexible and changeable requirements of tunnel construction. At the same time, when the width of the distribution box is relatively large, the top baffle of the traditional protection structure often cannot completely cover its top, resulting in poor protection effect and potential safety hazards. Therefore, in view of the above technical problems, a safety protection structure for a distribution box in tunnel construction is proposed here. Content of the Utility Model

[0004] The purpose of the utility model is to provide a safety protection structure for a distribution box in tunnel construction, which can adaptively adjust the internal space of the protection structure according to the size of the distribution box. It can not only be applicable to distribution boxes of various sizes, but also greatly improve the space utilization rate in the tunnel, and can extend the extension plate outward to fully cover the upper end of the distribution box, greatly improving the protection range of this structure.

[0005] The utility model is realized through the following technical solutions:

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figures 1-7 , a safety protection structure for a tunnel construction distribution box proposed by the present utility model, including a bottom plate 1, several groups of equally spaced vertical rods 2 fixedly connected to the upper side of the bottom plate 1, a lifting rod 3 slidably connected to the upper end of the vertical rod 2, through holes 4 are opened on the outer parts of the vertical rod 2 and the lifting rod 3, and the through holes 4 opened on the lifting rod 3 are arranged at equal intervals. A linkage positioning mechanism is installed on the outer part of the vertical rod 2. The top of the lifting rod 3 is fixedly connected with a top baffle 10. An installation groove 11 is opened on the outer part of the top baffle 10. An extension plate 12 is slidably connected to the inside of the installation groove 11. A toothed plate 13 is fixedly connected to the bottom of the extension plate 12. A driving motor 14 is fixedly connected to the outer part of the top baffle 10. A telescopic mechanism is installed inside the installation groove 11.

[0025] The linkage positioning mechanism includes a sliding rod 5, a connecting plate 6, a spring 7 and a connecting rod 8. The sliding rod 5 is slidably connected to the inside of the through hole 4, and the sliding rod 5 penetrates through the vertical rod 2 and the lifting rod 3. The connecting plate 6 is fixedly connected to the sliding rod 5. The spring 7 is fixedly connected between the connecting plate 6 and the vertical rod 2, and the spring 7 is sleeved on the outer side of the sliding rod 5.

[0026] The connecting rod 8 is fixedly connected between two groups of connecting plates 6. By controlling the movement of the connecting rod 8, all the connecting plates 6 can be controlled to move accordingly, achieving a linkage effect.

[0027] A reinforcing rod 9 is fixedly connected between two adjacent groups of vertical rods 2, and the protective strength of this structure can be enhanced through the reinforcing rod 9.

[0028] The telescopic mechanism includes a rotating rod 15 and a gear 16. The rotating rod 15 is rotatably connected to the inner side of the installation groove 11. The gear 16 is fixedly connected to the outside of the rotating rod 15, and the gear 16 meshes with the toothed plate 13. The rotating rod 15 is fixedly connected to the driving motor 14.

[0029] Blocking plates 17 are fixedly connected to both sides of the upper end of the bottom plate 1. A sliding plate 18 is fixedly connected to the bottom of the top baffle 10, and the sliding plate 18 is slidably connected to the blocking plates 17. By providing the blocking plates 17 and the sliding plate 18, the protection of the left and right sides of the distribution box can be achieved.

[0030] Based on the working principle of a safety protection structure for a tunnel construction distribution box in the embodiment, before use, when adjusting the internal space of this protection structure according to the size of the distribution box, first, the connecting rod 8 can be pulled, which can drive all the connecting plates 6 to drive the sliding rods 5 connected thereto to be pulled out and stretch the spring 7, thereby releasing the lifting rod 3, enabling it to contract up and down within the vertical rod 2 for adjustment until it can be fully adapted to the size of the distribution box. Align the through holes 4 on the surfaces of the vertical rod 2 and the lifting rod 3. Then, release the connecting rod 8, and the connecting plates 6 can drive the sliding rods 5 to be reinserted into the through holes 4 under the drive of the spring 7, thus completing the positioning of the vertical rod 2 and the lifting rod 3. In this way, the internal space of the protection structure can be adaptively adjusted according to the size of the distribution box, which can not only be applicable to distribution boxes of various sizes but also greatly improve the space utilization rate in the tunnel. Moreover, when the distribution box is placed inside this structure for protection, if its width is relatively wide and the top baffle 10 cannot completely cover and protect its top, at this time, the driving motor 14 can be operated to drive the rotating rod 15 to drive the gear 16 to rotate. Since the toothed plate 13 meshes with the gear 16, the extension plate 12 can be extended outward to provide full coverage protection for the upper end of the distribution box, greatly improving the protection range of this structure.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
