Description

Technical Field

[0001] This utility model relates to the field of safety protection facilities technology, specifically a safety fence for power plant maintenance. Background Technology

[0002] During power plant maintenance, the complex and diverse equipment necessitates fencing to protect the maintenance area and ensure worker safety. However, since high-voltage electrical equipment may be involved, strict control over personnel and equipment access is crucial. This necessitates the use of an efficient and safe fencing system that effectively restricts personnel access while also considering the practicality and environmental adaptability of the protective measures.

[0003] Traditional safety fences typically employ a telescopic pole structure, such as the fence design in patent number CN216714059U. This type of fence is primarily constructed by connecting multiple poles to form a telescopic frame, usually with relatively large gaps between them. However, the large gaps between the poles result in poor interception of small animals, failing to effectively prevent them from entering the maintenance area. For high-security locations like power plants, traditional pole-type telescopic fences have certain shortcomings in terms of protective capabilities and security, especially in preventing small animals from entering, which can easily create potential safety hazards. Therefore, existing technology urgently needs improvement to enhance the practicality and safety of fences in power plant maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a safety fence for power plant maintenance, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety fence for power plant maintenance, comprising a base, a support frame on the base, two openings on the support frame, and a guardrail mechanism inside the support frame.

[0006] The panel mechanism includes:

[0007] A rotating rod, which is rotatable about its own axis, is disposed inside the support frame;

[0008] A panel, comprising multiple panels that are rotatably connected in pairs, wherein the first panel is connected to the rotating rod and the last panel is connected to a positioning rod.

[0009] A slot, wherein the slot is disposed on the base;

[0010] A braking assembly, which is disposed on the support frame, is used to limit the rotation of the rotating rod.

[0011] Preferably, the braking assembly includes:

[0012] An extension section is provided at one end of the rotating rod and rotatably connected to the base. The extension section is located at the other end of the rotating rod and has several first positioning holes.

[0013] A groove, wherein the groove is formed on the support frame;

[0014] The top cover is provided with a first positioning post that matches the first positioning hole and a protruding part that matches the groove.

[0015] Preferably, the support frame is provided with a second positioning hole, and the top cover is provided with a second positioning post that matches the second positioning hole.

[0016] Preferably, the base is provided with a limiting post.

[0017] Preferably, the railing has an arc-shaped structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This safety fence for power plant maintenance effectively reduces the height of the fence from the construction ground by setting arc-shaped panels and spacing of less than 3cm, thereby reducing the possibility of small animals entering the maintenance area. In addition, the arc-shaped design of the panel structure helps to improve space utilization and facilitates storage, ensuring that the panels can be easily retracted into the support frame, thus improving the convenience and space management efficiency during use. Furthermore, this design allows for adjustment of the extended length of the panels as needed and fixation by the top cover, making it highly adaptable. Attached Figure Description

[0031] Example

[0032] Please see Figure 1-6As shown, the present invention provides a safety fence for power plant maintenance: a safety fence for power plant maintenance includes a base 1, a support frame 2 on the base 1, two openings 3 on the support frame 2, and a guardrail mechanism 4 inside the support frame 2.

[0033] The balustrade mechanism 4 includes a rotating rod 401, a balustrade 402, a slot 404, and a braking assembly 405. The rotating rod 401 is rotatable around its own axis and is located inside the support frame 2. The balustrade 402 includes multiple balustrade panels 4021 that are rotatably connected in pairs. The balustrade panel 4021 at the first end is connected to the rotating rod 401, and the balustrade panel 4021 at the end is connected to a positioning rod 403. The slot 404 is located on the base 1, and the braking assembly 405 is located on the support frame 2. The braking assembly 405 is used to limit the rotation of the rotating rod 401.

[0034] like Figure 2-3 As shown, fixing plates are further provided on the periphery of slot 404 and the top of rotating rod 401 to achieve the stability of the overall structure.

[0035] During installation, the operator first needs to fix the base 1 to the road surface under maintenance, then pull out the guardrail 402, and after a suitable length, insert the positioning rod 403 at the end of the guardrail 402 into the slot 404. Finally, the rotation of the rotating rod 401 is restricted by the braking assembly 405.

[0036] The braking assembly 405 includes an extension 4051, a groove 4053, and a top cover 4054. One end of the rotating rod 401 is rotatably connected to the base 1. The extension 4051 is located at the other end of the rotating rod 401. The extension 4051 has several first positioning holes 4052. The groove 4053 is located on the support frame 2. The top cover 4054 has first positioning pins 4055 that match the first positioning holes 4052 and protrusions 4056 that match the grooves 4053.

[0037] In this embodiment, the structure of the groove 4053 is as follows: Figure 3 As shown, the structure of the protruding portion 4056 is as follows: Figure 6 As shown.

[0038] When braking the rotating rod 401, the operator needs to rotate the rotating rod 401 appropriately. After ensuring that the first positioning hole 4052 and the first positioning post 4055 are aligned, the rod is fixed. After fixing, the protruding part 4056 will be placed in the groove 4053, and the friction between them will prevent the rotating rod 401 from rotating.

[0039] The support frame 2 is provided with a second positioning hole 5, and the top cover 4054 is provided with a second positioning post 6 that matches the second positioning hole 5. This design can further enhance the limiting effect of the top cover 4054 on the rotating rod 401, and ensure that the top cover 4054 remains fixed after docking with the first positioning hole 4052 and no longer rotates.

[0040] The base 1 is equipped with a limiting post 7. This design can restrict the position of the guardrail 402 after it is inserted into the support frame 2, so as to avoid collision between the guardrails 402 during transportation and damage to the connecting structure.

[0041] The parapet 402 has an arc-shaped structure, which helps to improve space utilization and ensures that the parapet 402 can be effectively stored in the support frame 2.

[0042] The distance between the guardrail 402 and the base is less than 3cm. This design effectively reduces the height of the guardrail 402 from the construction ground, thereby further reducing the possibility of small animals entering the maintenance area.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
