Description

Technical Field

[0001] This application relates to the field of power grid equipment maintenance technology, specifically to a busbar safety fence. Background Technology

[0002] Currently, when performing maintenance work on 220kV GIS busbars, the safety measures to isolate them from adjacent operating busbars are typically implemented by using safety barriers with "Stop, High Voltage Danger" signs. However, since busbars are usually located at a high position, these safety barriers also need to be correspondingly high, and are usually fixed to the busbars by hanging. Therefore, cable ties are required to ensure the safety measure is stable and does not fall, which exposes workers to the risks of working at height when setting up the safety barriers.

[0003] Furthermore, if escalators are required for high-altitude work, the GIS busbar is typically quite long, and the safety railing needs multiple fixed points, which are set up along the busbar. Each time a worker secures a fixed point, they must move the escalator to the next fixed point. This process is time-consuming, labor-intensive, and extremely dangerous for workers at height. Summary of the Invention

[0004] This application is primarily intended to improve the efficiency and safety of deploying busbar safety fences.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a busbar safety fence, including a fixing component and a safety barrier. The fixing component includes a hook and a movable component. The hook includes a hook body and a first connecting part. The hook body has a groove. The movable component includes a top abutment, a connecting rod, and a docking part. The top abutment and the docking part are disposed on the connecting rod. The top abutment faces the groove. The connecting rod is movably connected to the first connecting part. The docking part is used to dock with an operating rod and, under the control of the operating rod, moves the top abutment and the connecting rod relatively closer to or away from the groove. The top abutment is used to abut the corrugated pipe connecting rod to confine the corrugated pipe connecting rod in the groove. The safety barrier includes a barrier body and a second connecting part. The second connecting part is disposed on the barrier body and is connected to the first connecting part.

[0006] In one specific embodiment, the connecting rod includes a lead screw, the first connecting portion has a first screw hole, the lead screw engages with the first screw hole, the docking portion is fixed to one end of the lead screw, and the abutment is rotatably connected to the other end of the lead screw. When the operating rod drives the docking portion to rotate, the lead screw rotates relative to the first screw hole, and the movable part moves relative to the hook.

[0007] In one specific embodiment, there are multiple second connecting parts, and the multiple second connecting parts are evenly arranged on the edge of the enclosure body parallel to the extension direction of the corrugated pipe connecting rod. The number of fixing components corresponds to the number of second connecting parts.

[0008] In one specific embodiment, the edge of the enclosure body includes an upper edge and a lower edge spaced apart. The upper edge and the lower edge are parallel to the extending direction of the corrugated pipe connecting rod. The plurality of second connecting parts are evenly arranged on the upper edge and the lower edge. The fixing component adjacent to the upper edge and the fixing component adjacent to the lower edge are connected to different corrugated pipe connecting rods.

[0009] In one specific embodiment, the safety fence further includes a splicing component, which is disposed on the edge of the fence body, and two adjacent fence bodies are connected by the splicing component; wherein, the splicing component includes a zipper, the zipper includes two corresponding chain straps and a pull tab, one chain strap is disposed on one fence body, the other chain strap is disposed on another adjacent fence body, and the pull tab is used to slide along the chain straps to engage the two chain straps and connect the two fence bodies.

[0010] In one specific embodiment, the extension direction of the zipper is perpendicular to the extension direction of the corrugated tube connecting rod.

[0011] In one specific embodiment, the main body of the enclosure includes a flexible fabric and a fixing frame. The fixing frame includes a longitudinal fixing rod, which is arranged parallel to the extension direction of the zipper. The second connecting part, the upper edge, and the lower edge are connected to the flexible fabric.

[0012] In one specific embodiment, the fixing frame further includes two transverse fixing rods, which are connected to the longitudinal fixing rod. The transverse fixing rods are parallel to the extension direction of the corrugated pipe connecting rod and are respectively connected to the upper edge and the lower edge.

[0013] In one specific embodiment, the fixing frame comprises a hollow tube.

[0014] In one embodiment, the flexible fabric has warning colors, patterns and / or text, and the surface of the flexible fabric is uniformly provided with a plurality of ventilation holes.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, in this embodiment, the groove of the hook accommodates the corrugated pipe connecting rod, and the top of the hook facing the groove limits the position of the corrugated pipe connecting rod within the groove, thereby detachably connecting the fixing component and the corrugated pipe connecting rod. Furthermore, since the hook also connects to the safety barrier, the safety barrier can be relatively fixed to the corrugated pipe connecting rod under the action of the fixing component. Because the fixing component has a mating part, the process of hanging the busbar safety fence onto the corrugated pipe connecting rod can be performed by workers using an operating rod, eliminating the need for workers to frequently move positions and / or climb to high places for complex high-altitude operations, thus improving the safety of deploying the busbar safety fence. Moreover, using an operating rod is simpler and less strenuous than using cable ties, and the structure provided in this application also greatly improves the efficiency of deploying the busbar safety fence.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application.

[0029] Currently, when performing maintenance work on 220kV GIS (Gas Insulated Switchgear) busbars, when it comes to setting up safety measures to isolate them from adjacent operating busbars, workers typically use safety barriers with "Stop, High Voltage Danger" signs. GIS busbars are usually equipped with busbar corrugated pipes, and adjacent sections of corrugated pipes are connected and fixed using corrugated pipe connecting rods. For commonly used safety barriers, the fixing points can be set on the corrugated pipe connecting rods. After fixing the safety barrier to the corrugated pipe connecting rods using cable ties, the safety barrier can cover the busbar corrugated pipes on at least one side, thus achieving a protective and warning effect.

[0030] However, since the busbar is usually located at a high position, the height of this safety fence also needs to be set accordingly. It is typically fixed to the busbar by suspension. Therefore, cable ties are needed to ensure the safety measure is stable and does not fall, which exposes workers to the risks of working at height when installing the safety fence.

[0031] Furthermore, if escalators are required for high-altitude work, the GIS busbar is typically quite long, and the safety railing needs multiple fixed points, which are set up along the busbar. Each time a worker secures a fixed point, they must move the escalator to the next fixed point. This process is time-consuming, labor-intensive, and extremely dangerous for workers at height.

[0032] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0033] See Figures 1 to 6 , Figure 1 This is a schematic diagram of the assembly structure of an embodiment of the busbar safety fence provided in this application. Figure 2 This is a schematic diagram of the assembly structure of another embodiment of the busbar safety fence provided in this application. Figure 3 This is a schematic diagram of the assembly structure of another embodiment of the busbar safety fence provided in this application. Figure 4 This is a cross-sectional structural diagram of the busbar safety fence and operating rod provided in this application. Figure 5 yes Figure 4 A magnified schematic diagram of a portion of region A in the middle. Figure 6 yes Figure 4 A partially enlarged structural diagram of region B. This application provides a busbar safety fence 1, which is hung on the corrugated pipe connecting rod 4 to provide protection and warning, ensuring the maintenance of the GIS busbar. The busbar safety fence 1 includes a fixing component 2 and a safety fence.

[0034] The fixing component 2 may include a hook 21 and a movable component 23. The hook 21 includes a hook body 211 and a first connecting portion 22, and the hook body 211 has a groove 212. The movable component 23 includes a top abutment 231, a connecting rod 232, and a mating portion 233. The top abutment 231 and the mating portion 233 are disposed on the connecting rod 232, and the top abutment 231 faces the groove 212. The connecting rod 232 is movably connected to the first connecting portion 22. The mating portion 233 is used to engage with the operating rod 6 and, under the control of the operating rod 6, moves the top abutment 231 and the connecting rod 232 relatively closer to or further away from the groove 212. The top abutment 231 is used to abut the corrugated pipe connecting rod 4 to confine the corrugated pipe connecting rod 4 within the groove 212. The safety barrier 3 may include a barrier body 31 and a second connecting portion 33. The second connecting portion 33 is disposed on the barrier body 31 and is connected to the first connecting portion 22.

[0035] In the structure provided in the embodiment, the groove 212 of the hook 21 accommodates the corrugated pipe connecting rod 4, and the top 231 facing the groove 212 limits the corrugated pipe connecting rod 4 within the groove 212, thereby detachably connecting the fixing component 2 and the corrugated pipe connecting rod 4. Since the hook 21 is also connected to the safety barrier 3, the safety barrier 3 can be relatively fixed to the corrugated pipe connecting rod 4 under the action of the fixing component 2. Because the fixing component 2 has a mating part 233, the process of hanging the busbar safety fence 1 onto the corrugated pipe connecting rod 4 can be performed by the operator using the operating rod 6. This eliminates the need for the operator to frequently move positions and / or climb to high places for complex high-altitude operations, improving the safety of deploying the busbar safety fence 1 and reducing the manpower and material consumption during deployment. Furthermore, using the operating rod 6 is simpler and less labor-intensive than manually binding with cable ties, and the structure provided in this application also greatly improves the efficiency of deploying the busbar safety fence 1.

[0036] Specifically, such as Figure 5 As shown, the second connecting part 33 may be provided with a connecting hole 331, and the first connecting part 22 may be provided with a second screw hole 222, with the connecting hole 331 and the second screw hole 222 correspondingly opened. The busbar safety fence 1 may also include a locking screw 7, which is used to pass through the connecting hole 331 and screw into the second screw hole 222, thereby connecting the second connecting part 33 and the first connecting part 22.

[0037] In one specific embodiment of this application, the connecting rod 232 may include a lead screw, and the first connecting portion 22 has a first screw hole 221, with the lead screw engaging with the first screw hole 221. The mating portion 233 may be fixed to one end of the lead screw, and the abutment 231 may rotatably connect to the other end of the lead screw. When the operating lever 6 drives the mating portion 233 to rotate, the lead screw may rotate relative to the first screw hole 221, and the movable member 23 may move relative to the hook 21.

[0038] With the structure provided in this embodiment, the docking part 233 docks with the operating rod 6, so that the movable part 23 can rotate under the control of the operating rod 6. Due to the meshing relationship between the lead screw and the first screw hole 221, the movable part 23 can move closer to or away from the groove 212 as the rotation direction is adjusted. Since the abutment 231 is rotatably connected to the lead screw, the abutment 231 does not rotate synchronously while moving closer to or away from the groove 212 with the lead screw. This allows for flexible control of the distance between the abutment 231 and the groove 212, thereby enabling flexible operation and adaptability to bellows connecting rods 4 of different sizes, improving the versatility of the fixing component 2.

[0039] In one specific embodiment of this application, there can be multiple second connecting portions 33. These multiple second connecting portions 33 can be evenly arranged along the edge of the enclosure body 31, parallel to the extending direction of the corrugated pipe connecting rod 4. The number of fixing components 2 corresponds to the number of second connecting portions 33.

[0040] For busbar safety fences 1 used for protection and warning purposes, the length and width are usually large to ensure they are conspicuous enough and effectively conceal the GIS busbar sections that need protection, such as SF6 pressure gauges. The length refers to the dimension along the extension direction of the corrugated pipe connecting rod 4, while the width refers to the dimension perpendicular to the corrugated pipe connecting rod 4.

[0041] Therefore, for busbar safety fences 1 with large length and width, multiple second connecting parts 33 and multiple fixing components 2 can be set to evenly distribute the mass of busbar safety fence 1, reduce the sway amplitude of busbar safety fence 1, and thus stably fix busbar safety fence 1 to corrugated pipe connecting rod 4, thereby improving the stability and safety of GIS busbar maintenance operations.

[0042] In one specific embodiment of this application, the edge of the enclosure body 31 includes an upper edge 312 and a lower edge 313 spaced apart. The upper edge 312 and the lower edge 313 are parallel to the extending direction of the corrugated pipe connecting rod 4. A plurality of second connecting parts 33 are evenly disposed on the upper edge 312 and the lower edge 313. The fixing component 2 adjacent to the upper edge 312 and the fixing component 2 adjacent to the lower edge 313 are connected to different corrugated pipe connecting rods 4.

[0043] To serve as a warning, the busbar safety fence 1 is typically not installed parallel to the horizontal plane. Therefore, the upper edge 312 can be the higher edge of the fence body 31 in the vertical direction, and the lower edge 313 can be the lower edge of the fence body 31 in the vertical direction. The fixing components 2 adjacent to the upper edge 312 and the lower edge 313 are respectively connected to different corrugated pipe connecting rods 4, thereby creating a pulling effect at multiple points on the fence body 31. This causes the fence body 31 to unfold between different corrugated pipe connecting rods 4, reducing the swaying amplitude of the busbar safety fence 1 and improving structural stability, thus fully achieving the effects of protection and warning.

[0044] Among them, see Figure 1 , Figure 2 There are usually multiple corrugated pipe connecting rods 4 used to connect the corrugated pipes. Multiple corrugated pipe connecting rods 4 form a hexahedron around the busbar corrugated pipe 5. The busbar safety fence 1 can be installed on the side of the hexahedron that is vertical and along the length of the busbar corrugated pipe 5. The fixing components 2 adjacent to the upper edge 312 and the lower edge 313 can be fixed on the two corrugated pipe connecting rods 4 that form this surface, so that the busbar safety fence 1 can just cover the side of the busbar corrugated pipe 5, and fully achieve the effect of protection and warning.

[0045] like Figure 5 As shown, under the influence of gravity, the groove 212 on the hook 211 adjacent to the upper edge 312 is oriented downwards. Figure 6 In the case of the safety enclosure 3, due to the width of the enclosure, the lower edge 313 is lower than the adjacent lower corrugated pipe connecting rod 4, so the groove 212 on the hook 211 adjacent to the lower edge 313 is also oriented downwards. However, if the lower edge 313 is higher than the adjacent lower corrugated pipe connecting rod 4, the groove 212 on the hook 211 adjacent to the lower edge 313 can also be oriented upwards.

[0046] Optionally, the bellows connecting rod 4 can be a column, and the fixing component 2 can rotate relative to the bellows connecting rod 4. The top abutment 231 can be provided with a mating groove 231a, the contour shape of which matches the contour shape of the outer periphery of the bellows connecting rod 4. This allows for a tight fit with the bellows connecting rod 4 when it abuts, improving the stability of the connection between the fixing component 2 and the bellows connecting rod 4.

[0047] In one specific embodiment of this application, the safety fence 3 may further include a splicing member 32, which is disposed on the edge of the fence body 31, and two adjacent fence bodies 31 can be connected by the splicing member 32.

[0048] Due to the required length of the busbar safety fence 1, the safety barrier 3 is also relatively long. However, different GIS busbars have different installation requirements. An excessively long or short safety barrier 3 may not meet the needs of some GIS busbars, thus affecting the versatility of the busbar safety fence 1. Furthermore, an excessively long safety barrier 3 is also inconvenient for installation, transportation, and storage, making it very troublesome to use.

[0049] Therefore, the edges of the main body of the enclosure 31 can be equipped with splicing parts 32, which allow workers to connect two main bodies of the enclosure 31 together to meet the needs of the site. During transportation and storage, multiple enclosure bodies 31 can also be disassembled and stored separately without taking up excessive storage space.

[0050] Optionally, the splicing component 32 may specifically include a zipper 32a, which may include two corresponding chain straps 322 and a zipper pull 323. One chain strap 322 is disposed on one enclosure body 31, and the other chain strap 322 is disposed on an adjacent enclosure body 31. The zipper pull 323 is used to slide along the chain straps 322 to engage the two chain straps 322, thereby connecting the two adjacent enclosure bodies 31.

[0051] In one specific embodiment of this application, the extension direction of the zipper 32a can be perpendicular to the extension direction of the corrugated pipe connecting rod 4. A zipper 32a perpendicular to the extension direction of the corrugated pipe connecting rod 4 can effectively divide the length of the safety barrier 3.

[0052] The safety barrier 3 is typically made of flexible plastic or fabric. Compared to a complete, longer safety barrier 3, the safety barrier 3 formed by connecting multiple barrier bodies 31 via zippers 32a has higher strength and rigidity due to the higher strength and rigidity of the meshing parts of the two chain straps 322. This results in greater resistance to deformation, reducing the swaying amplitude of the busbar safety fence 1 and improving structural stability. Furthermore, the zippers 32a also help the safety barrier 3 unfold in the width direction, further enhancing the stability of the busbar safety fence 1.

[0053] In one specific embodiment of this application, the main body 31 of the enclosure may specifically include a flexible fabric 311 and a fixing frame 9. (See also...) Figure 7 , Figure 8 , Figure 7 This is a structural schematic diagram of an embodiment of the fence body provided in this application. Figure 8 This is a structural schematic diagram of another embodiment of the enclosure body provided in this application. The fixing frame 9 may include a longitudinal fixing rod 91, which is arranged parallel to the extension direction of the zipper 32a. The second connecting part 33, the upper edge 312, and the lower edge 313 are connected to the flexible fabric 311.

[0054] The structure provided by this specific embodiment can provide further support to the main body 31 of the enclosure by using the longitudinal fixing rod 91 on the basis of the zipper 32a, which helps the flexible fabric 311 to unfold in the width direction, making it less likely to roll up, and can reduce the swaying amplitude of the busbar safety fence 1, improve the structural stability, and thus play a more stable role in protection and warning.

[0055] In one specific embodiment of this application, the fixing frame 9 may further include two transverse fixing rods 92. The two transverse fixing rods 92 are connected to the longitudinal fixing rod 91, and the transverse fixing rods 92 are parallel to the extension direction of the corrugated pipe connecting rod 4, and are respectively connected to the upper edge 312 and the lower edge 313.

[0056] In the structure provided in this specific embodiment, two transverse fixing rods 92 are respectively adjacent to the upper edge 312 and the lower edge 313, thereby helping the flexible fabric 311 to unfold in the length direction, making it less prone to rolling up, and thus enabling it to more stably perform its protective and warning functions. Furthermore, due to the mass of the transverse fixing rod 92 itself at the lower edge 313, the flexible fabric 311 can also unfold in the width direction under the action of gravity. Through the cooperation of the transverse fixing rods 92 and the longitudinal fixing rods 91, the flexible fabric 311 can be unfolded, reducing the swaying amplitude of the busbar safety fence 1, improving structural stability, and thus fully exerting its protective and warning functions.

[0057] Figure 7 , Figure 8 Two different fixed frame 9 structures are shown. Figure 7 In the structure of the enclosure body 31 embodiment shown, there are two longitudinal fixing rods 91. The two longitudinal fixing rods 91 are arranged on the left and right sides of the flexible fabric 311, so that the two longitudinal fixing rods 91 can cooperate with the two transverse fixing rods 92 to form an approximately quadrilateral fixing frame 9.

[0058] exist Figure 8 In the structure of the enclosure body 31 embodiment shown, there is one longitudinal fixing rod 91. One longitudinal fixing rod 91 is set in the middle of the flexible fabric 311, and the two ends of the longitudinal fixing rod 91 are respectively connected to two transverse fixing rods 92, thereby forming a fixing frame 9 that is approximately "I" shaped.

[0059] It should be noted that, Figure 7 , Figure 8 For illustrative purposes only, the number of longitudinal fixing rods 91 and transverse fixing rods 92, and the connection method between them, are not intended to be arbitrary. Figure 7 , Figure 8 The structures shown are limited.

[0060] In one specific embodiment of this application, the fixing frame 9 may include a hollow tube.

[0061] While the presence of the fixing frame 9 provides support for the flexible fabric 311 and improves the structural strength of the busbar safety fence 1, it also increases the mass of the busbar safety fence 1 and the burden on the corrugated pipe connecting rod 4. Therefore, the fixing frame 9 may include a hollow tube, thereby reducing the mass of the busbar safety fence 1 to a certain extent without excessively affecting its structural strength, and improving the stability and safety of GIS busbar maintenance operations.

[0062] In one specific embodiment of this application, the flexible fabric 311 may have warning colors, patterns, and / or text. For example... Figure 1 , Figure 2 As shown, the flexible fabric 311 can have a warning sign that reads "Stop at High Voltage Danger" to warn personnel who are not involved in the work, reduce the probability of emergencies during GIS busbar maintenance, and improve the safety of GIS busbar maintenance.

[0063] Optionally, the flexible fabric 311 can be set to a striking color such as yellow or red, thereby using color to achieve a warning effect.

[0064] Optionally, the surface of the flexible fabric 311 is uniformly provided with multiple ventilation holes 8. For the purpose of safety protection, the flexible fabric 311 has a certain area.

[0065] In the presence of airflow, the flexible fabric 311 may create some resistance to the airflow, causing it to deform and / or sway like a sail under the influence of the airflow. When the wind force is strong, the changes in the flexible fabric 311 may affect the corrugated pipe connecting rod 4 or even the busbar, causing the entire busbar to sway, which not only threatens the safety of personnel working at heights but may also cause power line failures.

[0066] To address this issue, the flexible fabric 311 provided in this embodiment can be uniformly provided with multiple ventilation holes 8. Airflow can pass through these ventilation holes 8 through the flexible fabric 311, reducing the deformation and swaying amplitude of the flexible fabric 311 caused by airflow, thereby reducing the impact of airflow on power lines and workers, improving the stability of the busbar safety fence 1, and effectively ensuring the safety of GIS busbar maintenance operations.

[0067] exist Figure 7 , Figure 8 Two different types of ventilation holes are shown in the diagram. Figure 7In the structure of the enclosure body 31 shown in the embodiment, the ventilation holes 8 are a plurality of near-circular through holes provided on the flexible fabric 311. The near-circular through holes can be formed directly on the flexible fabric 311 during the production of the flexible fabric 311, or they can be subsequently formed on the flexible fabric 311 using perforation equipment such as a perforation machine. In the latter case, the flexible fabric 311 originally located at the position of the near-circular through holes is removed during the perforation process.

[0068] exist Figure 8 In the structure of the illustrated enclosure body 31 embodiment, when no airflow passes through, the ventilation holes 8 are multiple arc-shaped fine holes provided on the flexible fabric 311. These arc-shaped fine holes can be formed directly on the flexible fabric 311 during production, or they can be subsequently created on the flexible fabric 311 using perforation equipment such as a perforation machine. The flexible fabric 311 within the circumference of the arc-shaped holes remains connected to the overall flexible fabric 311. When airflow passes through, this portion of the flexible fabric 311 will be lifted due to the presence of the ventilation holes 8, increasing the area of ​​the ventilation holes 8 and allowing airflow to pass through them.

[0069] For flexible fabric 311 printed with warning colors, patterns, and / or text, due to the absence of flexible fabric 311 at the near-circular through-holes, a method such as Figure 7 The shape of the ventilation opening 8 shown may not effectively maintain the integrity of the color, pattern, and / or text areas, thus potentially affecting the warning function of the busbar safety fence 1. However, using a design similar to... Figure 8 When the ventilation hole 8 is shaped as shown, the flexible fabric 311 within the circumference of the arc-shaped fine hole is not missing, thus maintaining the approximate integrity of the color, pattern and / or text area while airflow passes through, and better realizing the warning function of the busbar safety fence 1.

[0070] The above description is only a partial embodiment of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the scope of patent protection of this application.
