Description

Technical Field

[0001] The present invention relates to the technical field of substation safety protection warning technology, and in particular to a substation safety protection warning device. Background Art

[0002] Substations are an important part of the power system, responsible for increasing and decreasing voltage as well as transmitting and distributing electrical energy. Since power substations involve high-voltage electricity, they carry relatively high safety risks. Substations mainly include: box-type substations, outdoor substations, indoor substations, and underground substations. Here, we focus on box-type substations. To ensure the safe and stable operation of power substations and protect the lives and property of staff and the public, a series of strict safety protection measures must be taken. A common method is to set up guardrails outside the substation to restrict unauthorized personnel from entering the substation and prevent animals from breaking in.

[0003] Traditional fences are basically rectangular frame structures composed of horizontal and vertical bars and connected by welding or bolts. The right-angle connections are easily affected by wind loads, collisions, etc., which lead to stress concentration, and then cause local deformation or even fracture, affecting the overall protection stability. At the same time, the bottom of the fence is usually directly bolted to the ground, lacking effective anti-topple treatment. In the event of strong winds, excessive impact force or uneven foundation settlement (such as non-cement hard ground such as soil), it is easy to tilt or collapse as a whole, which makes it difficult to meet the protection needs of high-security areas. Summary of the Invention

[0004] In view of the above problems, the embodiments of the present application provide a substation safety protection warning device to solve the technical problems in the related art that the substation is prone to overall tilting or collapse and is difficult to meet the protection requirements of high-security level areas.

[0008] According to an embodiment of the present invention, a support rod is fixedly installed on the lower end of the two connecting plates of the same reinforcement and close to the side of the beam, and a close block is fixedly installed on the lower end of the support rod, which is close to the bottom beam. The close block is close to the bottom beam, and with the cooperation of the support rod, the reinforcement is supported.

[0009] According to an embodiment of the present invention, threaded holes are provided in the middle of the fastening block and the middle of the docking block, the upper end of the threaded hole of the docking block is provided with a chamfer, two bolts are threadedly connected in the threaded holes, and positioning plates are fixedly installed inside and outside the fastening block, and a slot that cooperates with the vertical beam of the guardrail is provided on the positioning plate on the outside.

[0010] According to an embodiment of the present invention, the docking part includes a horizontal plate, and the opposite ends of the two clamping blocks on the same horizontal beam are fixedly installed with a horizontal plate. Rectangular slots that match the vertical beams are evenly opened on the horizontal plate. Fixed plates are fixedly installed on both ends of the horizontal plate and located inside and outside the guardrail. The positioning plate and the fixed plate are both connected with T-shaped rods that slide up and down, and two bracket plates are fixedly installed on the lower ends of the positioning plate and the fixed plate.

[0011] According to an embodiment of the present invention, the two horizontal plates on the same horizontal beam are plugged in and out of each other in a clockwise order, an insert block is fixedly installed at the lower end of the joint of the upper horizontal plate, and a slot matching the insert block is provided at the upper end of the joint of the lower horizontal plate. The front horizontal plate on the right horizontal beam and the corresponding insert block are both provided with threaded holes, and a bolt is threadedly connected in the threaded hole.

[0012] According to an embodiment of the present invention, the fixing plate and the positioning plate are both connected with T-shaped rods for sliding up and down movement. A contact plate is inserted at the bottom of the T-shaped rod on the fixing plate, and the two contact plates located on the inner and outer sides of the same beam are correspondingly inserted.

[0014] According to an embodiment of the present invention, based on the environment of the ground where the substation is installed, when the ground soil is soft, conical plugs are evenly fixedly installed on the bottom of the contact plate. The conical plugs are existing technology and are not shown in the schematic diagram.

[0015] It can be seen from the above technical solutions that the present invention has the following advantages:

[0016] 1. In the present invention, a triangular structure is formed by cooperating with the crossbeam of the guardrail through the reinforcement piece. The geometric stability of the triangle is used to disperse the vertical pressure and horizontal impact force on the crossbeam to the vertical beam and the reinforcement piece, thereby improving the strength and impact resistance of the guardrail. The plug-in design is convenient for on-site assembly. The reinforcement piece cooperates with the docking piece and the supporting piece to form additional diagonal braces for the crossbeam and the vertical beam, thereby preventing the crossbeam and the vertical beam from bending and deforming due to external forces, thereby enhancing the anti-overturning ability of the upper part of the guardrail, and providing doubly supporting the guardrail to prevent it from tilting or collapsing, so as to achieve the purpose of meeting the protection requirements of high-safety level areas. At the same time, the cross plates in the docking piece must be fixed in a chain-like manner in sequence, which enhances the coordinated force of all reinforcement pieces while avoiding the situation where the reinforcement structure fails due to arbitrary disassembly by non-professionals, and ensures that a single reinforcement piece cannot be disassembled alone to prevent the loss of local structure from affecting the overall stability.

[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] See Figure 1 and Figure 2 A substation safety protection warning device includes a protection unit 1 and a guardrail. The four corners of the guardrail are each provided with a protection unit 1. The four protection units 1 are contacted and aligned with each other in a clockwise manner. The two opposite protection units 1 on the right side are fixedly connected by bolts 2. The protection unit 1 includes a reinforcement 11. The four corners of the crossbeam on the guardrail are each provided with a reinforcement 11. The reinforcement 11 and the crossbeam form a triangular structure to enhance the stability of the guardrail. A docking piece 12 is fixedly installed on the reinforcement 11 and above the crossbeam. Adjacent docking pieces 12 are contacted and aligned with each other. Symmetrical support pieces 13 are provided on the docking piece 12 and the reinforcement 11. The support piece 13 supports the docking piece 12 and the reinforcement 11.

[0031] See Figure 6 A rectangular groove is provided at the bottom of the vertical beam on the guardrail, and an extension plate 125 is connected to the rectangular groove for sliding up and down. A cylindrical spring 126 is fixedly installed between the upper end of the extension plate 125 and the rectangular groove. A fixed groove is provided in the middle of the outer contour of the extension plate 125, and a mesh bag is fixedly installed in the fixed groove. The width of the mesh bag is greater than the width of the fixed groove, and the mesh bag is filled with stone particles.

[0032] First, observe whether there is a gap between the bottom of the beam of the guardrail body and the ground. If there is a gap, the cylindrical spring 126 there drives the extension plate 125 to extend from the bottom of the beam to block the main position of the gap. At this time, the stone particles in the mesh bag move to the irregular edge of the gap under the action of gravity, and cooperate with the extension plate 125 to block the gap.

[0033] See Figure 2 、 Figure 7 and Figure 8 The two connecting plates 112 are staggered up and down, and the two connecting plates 112 are provided with a slot that matches the corresponding docking block 113. The outer ends of the two connecting plates 112 are slidably connected with a fastening block 114. The lower ends of the two connecting plates 112 of the same reinforcing member 11 and one side of the crossbeam are fixedly installed with a support rod 115. The lower end of the support rod 115 is fixedly installed with a close-fitting block 116 that is in close contact with the bottom crossbeam. The close-fitting block 116 is in close contact with the bottom crossbeam with the cooperation of the support rod 115 to support the reinforcing member 11.

[0034] See Figure 2 and Figure 4 The docking member 12 includes a transverse plate 121. The opposite ends of the two clamping blocks 111 on the same crossbeam are fixedly installed with transverse plates 121. Rectangular slots that match the vertical beams are evenly opened on the transverse plate 121. Fixed plates 122 are fixedly installed on the transverse plate 121 and at both ends inside and outside the guardrail. The two transverse plates 121 on the same crossbeam are plugged in clockwise order. The lower end of the docking point of the upper transverse plate 121 is fixedly installed with an insert block 123. The upper end of the docking point of the lower transverse plate 121 is provided with a slot that matches the insert block 123. The front cross plate 121 on the right crossbeam and the corresponding insert block 123 are both provided with threaded holes, and the threaded holes are threaded with bolts 2.

[0035] See Figure 1 and Figure 2The support member 13 includes a T-shaped rod 131, and the T-shaped rod 131 is connected to the fixed plate 122 for sliding up and down. Two bracket plates 132 are fixedly installed on the lower end of the fixed plate 122, and a rectangular plate 133 is fixedly installed on the lower end of the bracket plate 132 on the same side. The rectangular plate 133 slides up and down with the T-shaped rod 131. A telescopic rod 134 is hinged on the rectangular plate 133. The bottom of the telescopic rod 134 is smooth and is set to an arc surface. A fixed block 135 is fixedly installed on the T-shaped rod 131 and directly below the rectangular plate 133. A linkage rod 136 is hinged between the fixed block 135 and the lower part of the telescopic rod 134.

[0036] See Figure 2 、 Figure 7 and Figure 8 , threaded holes are provided in the middle of the fastening block 114 and the middle of the docking block 113, the upper end of the threaded hole of the docking block 113 is chamfered, and two bolts 117 are threadedly connected in the threaded holes. The fastening block 114 is fixedly installed with positioning plates 118 on the sides facing the box-type substation and away from the box-type substation. A T-shaped rod 131 is connected to the positioning plate 118 for sliding up and down, and two bracket plates 132 are fixedly installed at the lower end of the positioning plate 118. A slot that cooperates with the guardrail vertical beam is provided on the outer positioning plate 118.

[0037] It should be noted that the positioning plate 118 on the side facing the box-type substation is smaller than the positioning plate 118 on the side away from the box-type substation.

[0038] 113, and then the fastening block 114 is fixed to the outer side of the connecting plate 112. The surface prevents the connecting plate 112 from moving. At the same time, after the cross plates 121 on the two clamping blocks 111 on the previous reinforcement member 11 are connected to the corresponding vertical beams, the cross plates 121 on the two clamping blocks 111 on the next reinforcement member 11 move down and connect with the corresponding vertical beams. The cross plate 121 after the next installation is plugged into the adjacent cross plate 121 after the previous installation, until the plug block 123 on the cross plate 121 on the last installed clamping block 111 is inserted into the slot on the cross plate 121 on the first installed clamping block 111. At this time, insert the bolt 123 into the threaded hole to fix the cross plate 121 on the first installed clamping block 111 and the cross plate 121 on the last installed clamping block 111. When disassembling, the bolt 123 must be taken out and the disassembly must be carried out in a certain order.

[0039] See Figure 2 It should be noted that the installation order of the horizontal plate 121 is to install it in a clockwise direction. The horizontal plate 121 on the right side of the rear side is installed first, followed by the horizontal plate 121 on the left side of the rear side, and then the horizontal plate 121 on the left side of the front side, and finally the horizontal plate 121 on the right side of the front side. At this time, all the mounting plates form a whole and are fixed by bolts 12. Therefore, when disassembling, it is necessary to remove bolts 12, and then slightly lift up the horizontal plate 121 that was installed first, so that the horizontal plate 121 that was installed last can be removed first, and then disassemble it counterclockwise.

[0040] See Figure 2 and Figure 5 A contact plate 124 is inserted at the bottom of the T-shaped rod 131 on the fixed plate 122, and the two contact plates 124 located on the inner and outer sides of the same beam are correspondingly connected. According to the environment of the ground where the substation is installed, when the ground soil is soft, conical columns are evenly fixed on the bottom of the contact plate 124. The conical columns are existing technology and are not shown in the schematic diagram.

[0041] When the contact plate 124 at the bottom of the T-shaped rod 131 contacts the ground, the T-shaped rod 131 is squeezed and tends to move upward, which drives the inclination angle of the linkage rod 136 to change, and the inclination angle between the linkage rod 136 and the T-shaped rod 131 becomes smaller, thereby driving the inclination angle of the telescopic rod 134 to change, and the inclination angle between the telescopic rod 134 and the rectangular plate 133 becomes smaller, thereby driving the lower part of the telescopic rod 134 to move downward and fit closely to the ground, so that the contact plate 124 and the bottom of the telescopic rod 134 are both in close contact with the ground, so as to achieve the purpose of supporting the docking member 12 and the reinforcement member 11. At the same time, the contact plates 124 at the bottom of the T-shaped rod 131 on the same side are aligned and plugged in to increase stability. If the ground soil is soft, the tapered plug at the bottom of the contact plate 124 is inserted into the ground to further increase stability.
