[0001] This utility model relates to the field of fence technology, and in particular to warning fences used at construction sites within substations. Background Technology

[0002] During the construction and maintenance of substations, warning fences are usually used to surround the construction and maintenance site in order to warn passers-by and prevent outsiders from entering.

[0003] For modular warning fences, when workers assemble them at the construction and maintenance site, one worker needs to hold the fence while another worker uses bolts to fix the fence to the side wall of the post. Workers need to cooperate to assemble the fence, which results in low installation efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide warning barriers for construction sites within substations to address the issue of low installation efficiency caused by workers having to cooperate with each other to assemble the barriers while one worker holds them up and another uses bolts to fix them to the side wall of the posts.

[0005] Warning fences for construction sites within substations include: a fence body consisting of posts and protective fences, wherein the protective fences are assembled to both sides of the posts by fixing bolts;

[0006] The protective fence is symmetrically provided with connecting pieces on both sides, which are connected to the protective fence by hinges and fixed to the inside of the support post by fixing bolts.

[0007] It also includes warning signs, which are placed above the inside of the protective fence.

[0008] In one embodiment, the support post has slots on the side walls facing the protective fence on both sides, and the connecting piece is inserted into the inside of the slots. The other two side walls of the support post have through holes that communicate with the slots. Fixing bolts are inserted into the through holes to fix the connecting piece inserted into the slots.

[0009] In one embodiment, the slots on the side walls of the support are arranged in parallel and staggered patterns.

[0010] In one embodiment, the inner ends of the two sets of slots do not penetrate the outer wall of the support.

[0011] In one embodiment, the hinge is disposed on the side wall of the protective fence facing the construction site, and the maximum rotation angle of the hinge is 90 degrees.

[0012] In one embodiment, the support post, protective fence, and connecting piece are all made of FRP material.

[0013] In one embodiment, the warning sign is fixedly installed inside the upper part of the protective fence, and a plurality of warning lights are provided around the side wall of the warning sign facing the outside of the protective fence. The interior of the plurality of warning lights is provided with a posting slot for posting warning signs on the side wall of the warning sign.

[0014] In one embodiment, several sets of the warning lights are electrically connected, and the warning sign is internally provided with a power supply for powering the warning lights.

[0015] Beneficial effects

[0016] 1. By horizontally staggering slots on both sides of the support column, the connecting pieces on both sides of the protective fence are inserted into the slots. The connecting pieces on both sides of the protective fence on both sides of the support column are at the same height. The connecting pieces on both sides of the support column are fixed by fixing bolts through the through holes, which further fixes the protective fence on both sides. Therefore, the operator only needs to tighten the bolts once to fix the protective fence on both sides at the same time, which improves the efficiency of the worker's installation.

[0017] 2. The connecting piece is mounted on the side wall of the protective fence facing the construction site via a hinge, and the maximum rotation angle of the hinge is [degree].

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figures 1-5 This invention describes a warning fence for use at construction sites within substations.

[0028] In one embodiment, a warning fence for a construction site within a substation includes: a fence body 100, which consists of a support post 101 and a protective fence 102, wherein the protective fence 102 is assembled to both sides of the support post 101 by fixing bolts 104.

[0029] like Figure 2 , Figure 3 and Figure 5 As shown, the protective fence 102 is symmetrically provided with connecting pieces 103 on both sides. The connecting pieces 103 are connected to the protective fence 102 by hinges 107. The connecting pieces 103 are fixed to the inside of the support column 101 by fixing bolts 104. The support column 101, the protective fence 102 and the connecting pieces 103 are all made of FRP material.

[0030] The support column 101 has slots 106 on the side walls facing the protective fences 102 on both sides. The connecting piece 103 is inserted into the inside of the slot 106. The other two side walls of the support column 101 have through holes 105. The through holes 105 are interconnected with the slots 106. The through holes 105 are inserted into the inside of the through holes 105 to fix the connecting piece 103 inserted into the slot 106.

[0031] In this embodiment, slots 106 are symmetrically provided on the upper and lower sides of the support column 101 facing the protective fence 102. Connecting pieces 103, which are symmetrically arranged on the upper and lower sides of the protective fence 102 and rotated by hinges 107, are respectively inserted into the slots 106. The connecting pieces 103 on both sides are fixed by means of fixing bolts 104 passing through the through hole 105 and the connecting pieces 103 inside the slots 106. Workers only need to tighten the fixing bolts 104 once to fix the protective fence 102 on both sides at the same time, reducing the number of times workers tighten the fixing bolts 104 and thus improving the installation efficiency of workers.

[0032] The support post 101, protective fence 102 and connecting piece 103 in this application are all made of FRP material. FRP is a new type of material composed of reinforcing fiber and matrix resin. Its characteristics are excellent insulation performance. When installed and used in high-voltage environments such as substations, it can avoid the risk of electric shock. The material has high strength and light weight, making installation more convenient and labor-saving. In addition, the material is resistant to acid and alkali and anti-aging, and can meet the needs of outdoor installation.

[0033] like Figure 3 and Figure 5 As shown, the slots 106 on both sides of the support column 101 are opened in parallel and staggered manner; the inner ends of the two sets of slots 106 do not penetrate the outer side of the support column 101.

[0034] In this embodiment, the slots 106 on both sides of the support column 101 are arranged in parallel and staggered. When the worker inserts the connecting piece 103 into the slots 106 on both sides of the support column 101, the connecting pieces 103 on both sides are on the same horizontal plane, which makes it easy for the fixing bolt 104 to pass through the through hole 105. The connecting piece 103 inside the slot 106 is fixed by the fixing bolt 104. The worker only needs to tighten the fixing bolt 104 once to install and fix the connecting pieces 103 on both sides.

[0035] Two sets of slots 106 are also provided so that the inner ends of the slots 106 do not penetrate the outer wall of the support column 101, in order to prevent workers from excessively inserting the connecting pieces 103 into the slots 106, and the fixing bolts 104 cannot accurately penetrate the through holes 105 and the round holes on the side walls of the two sets of connecting pieces 103 to fix the two sets of connecting pieces 103.

[0036] like Figure 4 and Figure 5 As shown, hinge 107 is installed on the side wall of protective fence 102 facing the construction site, and the maximum rotation angle of hinge 107 is 90 degrees;

[0037] In this embodiment, the hinge 107 is installed on the side wall of the protective fence 102 facing the construction site, and the maximum rotation angle of the hinge 107 is 90 degrees. This ensures that when the worker installs the fence, when it reaches a corner, by rotating the fence 102 90 degrees towards the side facing the construction site, the connecting piece 103 can be inserted into the slot 106 on the side wall of the support column 101. Similarly, the two sets of connecting pieces 103 can be fixed by using the fixing bolt 104 through the through hole 105, which further increases the practicality of this utility model.

[0038] like Figure 1 and Figure 2 As shown, it also includes a warning sign 200, which is set inside the upper part of the protective fence 102. The warning sign 200 is fixedly set inside the upper part of the protective fence 102. Several warning lights 202 are provided around the side wall of the warning sign 200 facing the outside of the protective fence 102. The interior of the several warning lights 202 is provided with a posting slot 201 for posting warning signs on the side wall of the warning sign 200.

[0039] Several sets of warning lights 202 are electrically connected, and the warning sign 200 is equipped with a power supply for powering the warning lights 202.

[0040] In this embodiment, a warning sign 200 is fixedly installed on the upper inside of the protective fence 102. Several warning lights 202 are installed around the side wall of the warning sign 200 facing the outside of the protective fence 102. The warning sign 200 is equipped with a power supply for powering the warning lights 202. In dark weather, the power supply can be provided to the warning lights 202 to warn pedestrians of the existence of the protective fence 102 and prevent pedestrians or vehicles from colliding with the fence body 100 and causing injury.

[0041] Furthermore, a posting slot 201 is provided inside several warning lights 202 on the side wall of the warning sign 200, allowing workers to post warning signs to remind pedestrians or vehicles as needed.

[0042] Working principle: During installation, workers fix the support column 101 to the ground with bolts, and the spacing between two adjacent sets of support columns 101 is fixed according to the width of the protective fence 102. After the support column 101 is fixed, the workers insert the connecting pieces 103 into the slots 106 on both sides of the support column 101 in sequence. Then, by passing the fixing bolt 104 through the through hole 105 and tightening the fixing bolt 104 with a nut, the connecting pieces 103 inside the slot 106 are further fixed. The workers only need to tighten the fixing bolt 104 once to fix the connecting pieces 103 on both sides, which reduces the installation time and improves the installation efficiency.

[0043] When the worker installs the fence at the corner, he rotates the connecting piece 103 90 degrees toward the side of the protective fence 102 facing the construction site, and then inserts the connecting piece 103 into the slot 106. At this time, the protective fence 102 connected to the connecting piece 103, which has been rotated 90 degrees, is at a 90-degree angle to the support post 101. The worker can then fix it by using the fixing bolt 104 through the through hole 105.

[0044] Additional notes:

[0045] It should be noted that the warning lights 202 and other devices mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. The power supply for the warning lights 202 inside the warning sign 200 can be selected according to the actual situation.
