Description

Technical Field

[0001] This utility model relates to the technical field of substation safety protection equipment, and in particular to a power maintenance fence. Background Technology

[0002] In substation maintenance operations, existing fencing technology often requires manual erection and dismantling, which is cumbersome and inefficient. When substation maintenance is required, it is impossible to quickly complete the installation and dismantling of fencing in a short period of time, which increases the working time and labor intensity of operators and reduces work efficiency. Utility Model Content

[0003] This utility model provides a power maintenance fence that facilitates rapid installation and dismantling of the fence in a short time, reduces operational difficulty and time, improves installation efficiency, and enhances the safety management level of substations.

[0004] This utility model provides a power maintenance fence, which includes a warning tape assembly, a drive assembly, and a rotating rod. The rotating rod includes a rotating end and a mounting end located at opposite ends of the rod body. The rotating end is rotatably connected to the drive assembly, and the mounting end is used to install the warning tape assembly. The drive assembly includes a drive component, a transmission component, and a limiting component. The drive component drives the transmission component to rotate the rotating rod around a horizontal axis, thereby causing the mounting end to move in a direction away from or close to the ground, causing the rotating rod to stand up or fall down. The limiting component is tractively connected to the rotating rod and is used to limit the extreme positions of the rotating rod's rotation, so that the rotating rod stops in the standing or falling position.

[0005] This utility model's technical solution involves setting up a driving assembly and a rotating rod. The driving assembly includes a driving component, a transmission component, and a limiting component. The driving component drives the transmission component to rotate the rotating rod around a horizontal axis, causing the installation end to move in a direction away from or close to the ground, thus raising or lowering the rotating rod. The limiting component is connected to the rotating rod and limits its rotation to the extreme positions, ensuring the rotating rod stops at the raised or lowered position. This allows for quick and convenient installation of a fence during equipment maintenance and repair, ensuring the safety of operators without disrupting normal workflow. The power maintenance fence can be quickly erected or lowered for rapid installation and dismantling, significantly reducing manual operation time and labor intensity, and improving work efficiency.

[0006] According to the foregoing embodiments of this utility model, the transmission assembly includes a first output shaft, which is connected to the rotating end of the rotating rod. The rotation axis of the first output shaft is perpendicular to the rotation axis of the rotating rod. This utility model's technical solution, by directly connecting the first output shaft to the rotating rod, facilitates stable transmission, has a compact structure, and enables rapid standing or falling movements of the rotating rod, thereby improving the rotation response speed of the rotating rod.

[0007] According to the aforementioned embodiments of this utility model, the transmission assembly includes a second output shaft, a third output shaft, and a connecting rod structure. The second output shaft is rotatably connected to the rotating end of the rotating rod, and the third output shaft is rotatably connected to the rotating output end of the driving member. The connecting rod structure includes a first end and a second end arranged opposite to each other. The first end is rotatably connected to the second output shaft, and the second end is rotatably connected to the third output shaft. The rotating output end of the driving member sequentially drives the third output shaft, the first end, the second end, and the second output shaft to rotate, thereby driving the rotating end of the rotating rod to rotate. This utility model's technical solution achieves the flipping motion of the rotating rod by setting a connecting rod structure, allowing for flexible adjustment of the rotating rod's flipping angle and stroke. This adapts to the isolation requirements of different sites and heights, enhancing its applicability.

[0008] According to any of the foregoing embodiments of the present invention, the limiting component includes a positioning block and a triggering element. The positioning block rotates synchronously with the transmission component. The transmission component drives the rotating rod to stand up or fall down. When the transmission component drives the rotating rod to rotate to the limit position, the positioning block triggers the triggering element, and the driving element stops driving the rotation of the transmission component to lock the rotating rod in the standing or falling position.

[0009] According to the aforementioned embodiments of this utility model, the power maintenance fence further includes a movable mounting base, and a drive assembly is disposed inside the mounting base. The mounting base also includes a cover and a seat. The cover is detachably disposed on the top surface of the seat to open or close the seat. A receiving cavity is formed between the cover and the seat to accommodate the drive assembly. One side of the seat includes a first through hole, and at least a portion of the transmission assembly extends out of the first through hole and connects to a rotating rod. A first sealing structure is also provided between the cover and the seat, including a sealing strip disposed along the edge of the cover. This utility model's technical solution, by providing a movable mounting base and disposing of the drive assembly inside the mounting base, allows the mounting base to be placed directly on the ground or moved to different positions as needed. The drive assembly drives the rotating rod to stand upright, forming a fence without digging a pit, facilitating installation. This utility model's technical solution, by providing a first sealing structure, makes the power maintenance fence dustproof, rainproof, and waterproof, suitable for harsh environments, and extends its service life.

[0010] According to the aforementioned embodiments of this utility model, the power maintenance fence further includes a second sealing structure, which is disposed in the first through hole to seal the connection between the transmission component and the mounting base. By providing the second sealing structure, this utility model's technical solution makes the power maintenance fence dustproof, rainproof, and waterproof, helps ensure the long-term stable operation of the drive component, facilitates its application in harsh environments, and extends its service life.

[0011] According to the aforementioned embodiments of this utility model, the second sealing structure includes a sealing plate, a first sealing ring, and a second sealing ring. The sealing plate includes a first cover plate and a second cover plate. The first cover plate is disposed on the outer side of the seat body, and the second cover plate is located on the inner side of the seat body and correspondingly disposed with respect to the first cover plate. Both the first and second cover plates include a second through hole communicating with the first through hole. At least a portion of the transmission assembly can pass through the first and second through holes to the outside of the seat body. The first sealing ring is disposed at the second through hole of the first cover plate. The first cover plate also includes a mounting position for installing the second sealing ring, which is located near the side where the second cover plate is located. The second sealing ring is used to seal the connection between the first and second cover plates. This utility model's technical solution, by setting a sealing plate, a first sealing ring, and a second sealing ring, not only ensures the normal rotation of the transmission assembly but also facilitates dustproofing, rainproofing, and waterproofing, ensuring long-term stable operation of the drive assembly, making it suitable for harsh environments, and extending its service life.

[0012] According to the aforementioned embodiments of the present invention, the rotating end of the rotating rod includes two mounting walls arranged opposite to each other, and a mounting groove for mounting a transmission component is formed between the two mounting walls. The mounting walls and the transmission component are connected by fasteners, so that the transmission component can drive the rotating rod to rotate.

[0013] According to the aforementioned embodiments of this utility model, the warning tape assembly includes: a housing, a warning tape, and a sensing component. The housing is detachably connected to the mounting end of the rotating rod. The warning tape is coiled and retracted within the housing, which has an opening for the warning tape to be pulled out. The sensing component is disposed within the housing and includes a first sensing element and a second sensing element. The first sensing element is disposed on either side of the opening and is used to detect the stretching of the warning tape. The second sensing element is disposed at the bottom of the housing and is used to detect the connection between the housing and the mounting end. This utility model's technical solution, by providing a warning tape assembly including a warning tape and a sensing component, allows the warning tape to extend and connect with the adjacent power maintenance fence, forming a clear safety boundary. This effectively isolates the substation's maintenance area from live equipment, reduces the risk of accidental entry into dangerous areas, prevents operator misoperation, and thus improves the substation's safety management level.

[0014] According to the aforementioned embodiments of this utility model, the power maintenance fence also includes a control unit. The control unit is communicatively connected to the maintenance system to drive or stop the rotation of the drive component, thereby driving or stopping the rotation of the rotating rod driven by the drive transmission assembly. This utility model's technical solution, by connecting the control unit to the maintenance system, facilitates meeting error prevention requirements and linking it to operation tickets. The power maintenance fence can be operated on the unit intervals that need management, preventing the wrong area from being fenced off. When the unit interval is energized, it is impossible to issue a command to control the rotating rod of the power maintenance fence to fall.

[0015] This utility model's technical solution effectively isolates the maintenance area and energized equipment in a substation, forming a clear safety boundary, reducing the risk of accidental entry into dangerous areas, and preventing operator misoperation, thereby significantly improving the substation's safety management level. The power maintenance fence can be placed directly on the ground, and its erection or lowering is achieved by a drive component that rotates the rod, allowing for rapid installation or dismantling in a short time. This greatly reduces manual operation time and labor intensity, improving work efficiency. During equipment inspection and maintenance, safety intervals can be quickly and conveniently set up to ensure operator safety without disrupting normal workflows. The power maintenance fence can be customized according to the terrain conditions and protection requirements of different substations, enhancing adaptability. The range and height of the power maintenance fence can also be quickly adjusted according to actual conditions, facilitating refined substation management and improving management efficiency.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0036] This utility model provides a power maintenance fence that facilitates rapid installation and dismantling of the fence in a short time, reduces operational difficulty and time, improves installation efficiency, and enhances the safety management level of substations.

[0037] like Figures 1 to 3 As shown, this embodiment of the utility model provides a power maintenance fence, which includes a warning tape assembly 100, a drive assembly 200, and a rotating rod 300. The rotating rod 300 includes a rotating end 310 and a mounting end 320 located at opposite ends of the rod body. The rotating end 310 is rotatably connected to the drive assembly 200, and the mounting end 320 is used to mount the warning tape assembly 100.

[0038] like Figures 1 to 3 As shown, the drive assembly 200 includes a drive member 210, a transmission assembly, and a limiting assembly 260. The drive member 210 drives the transmission assembly to rotate the rotating rod 300 around the horizontal axis, thereby moving the mounting end 320 in a direction away from or close to the ground, causing the rotating rod 300 to stand up or fall down. The limiting assembly 260 is connected to the rotating rod 300 and is used to limit the extreme positions of the rotation of the rotating rod 300, so that the rotating rod 300 stops in the standing position or the fallen position.

[0039] This utility model's technical solution utilizes a drive assembly 200 and a rotating rod 300. The drive assembly 200 includes a drive component 210, a transmission component, and a limiting component 260. The drive component 210 drives the transmission component to rotate the rotating rod 300 around a horizontal axis, causing the mounting end 320 to move away from or near the ground, thus allowing the rotating rod 300 to stand up or fall down. The limiting component 260 is connected to the rotating rod 300 and limits its rotation to the extreme positions, ensuring the rotating rod 300 stops at either the upright or fallen position. During equipment maintenance and repair, this allows for quick and convenient installation of a fence, ensuring the safety of operators without disrupting normal workflow. The power maintenance fence can be quickly erected or lowered for rapid installation and dismantling, significantly reducing manual operation time and labor intensity, and improving work efficiency.

[0040] Specifically, in this embodiment, the drive component 210 is a worm gear reducer motor with a self-locking function, used to lock the rotating rod 300 in an upright or fallen state. In other embodiments, other forms of drive components 210 may also be used, and this application does not limit the form of the drive component 210.

[0041] like Figure 4 As shown, the transmission assembly includes a first output shaft 220, which is connected to the rotating end 310 of the rotating rod 300. The rotation axis of the first output shaft 220 is perpendicular to the rotation axis of the rotating rod 300. This invention, by directly connecting the first output shaft 220 to the rotating rod 300, facilitates stable transmission, has a compact structure, and enables the rotating rod 300 to quickly stand up or fall down, thus improving the rotation response speed of the rotating rod 300.

[0042] like Figure 5 As shown, the transmission assembly includes a second output shaft 230, a third output shaft 240, and a connecting rod structure 250. The second output shaft 230 is rotatably connected to the rotating end 310 of the rotating rod 300, and the third output shaft 240 is rotatably connected to the rotating output end of the driving member 210. The connecting rod structure 250 includes a first end 251 and a second end 252 arranged opposite to each other. The first end 251 is rotatably connected to the second output shaft 230, and the second end 252 is rotatably connected to the third output shaft 240. The rotating output end of the driving member 210 sequentially drives the third output shaft 240, the first end 251, the second end 252, and the second output shaft 230 to rotate, thereby driving the rotating end 310 of the rotating rod 300 to rotate. This utility model's technical solution achieves the flipping motion of the rotating rod 300 by setting the connecting rod structure 250. The flipping angle and stroke of the rotating rod 300 can be flexibly adjusted, adapting to the isolation requirements of different sites and different heights. It can be flexibly adjusted according to various tilt angle requirements on site, which is beneficial to enhancing applicability.

[0043] like Figure 4 As shown, the limiting component 260 includes a positioning block 261 and a trigger 262. The positioning block 261 rotates synchronously with the transmission component. The transmission component drives the rotating rod 300 to stand up or fall down. When the transmission component drives the rotating rod 300 to rotate to its limit position, the positioning block 261 can trigger the trigger 262, and the driving component 210 stops driving the rotation of the transmission component to lock the rotating rod 300 in the standing or falling position. In this embodiment, the trigger 262 is a magnetic blow-out switch. In other embodiments, other forms of trigger 262 may also be used, and this application does not limit the form of the trigger 262.

[0044] In one embodiment, the positioning block 261 detects the stroke of the connecting rod structure 250 by rotating the rod 300 to its limit position, thereby triggering the trigger element 262, which helps to further improve the positioning accuracy and self-locking reliability.

[0045] like Figure 4 As shown, the extreme positions of the rotating rod 300 include a first extreme position and a second extreme position. When the transmission assembly drives the rotating rod 300 to rotate to the first extreme position and the second extreme position, the corresponding positions of the positioning block 261 are respectively provided with trigger elements 262. When the transmission assembly drives the rotating rod 300 to rotate to the first extreme position, the transmission assembly drives the rotating rod 300 to stand up, the positioning block 261 triggers the trigger element 262 at the first extreme position, and the driving member 210 stops driving the rotation of the transmission assembly to lock the rotating rod 300 in the standing position; when the transmission assembly drives the rotating rod 300 to rotate to the second extreme position, the transmission assembly drives the rotating rod 300 to fall down, the positioning block 261 triggers the trigger element 262 at the second extreme position, and the driving member 210 stops driving the rotation of the transmission assembly to lock the rotating rod 300 in the fallen position.

[0046] In this embodiment, the angle between the first and second extreme positions of the rotating rod 300 is 90°. When the rotating rod 300 rotates to the first extreme position, it stands vertically, the positioning block 261 triggers the trigger element 262, and both the transmission assembly and the rotating rod 300 stop rotating, locking the rotating rod 300 in the upright position. When the rotating rod 300 rotates to the second extreme position, it falls horizontally, the positioning block 261 triggers the trigger element 262, and both the transmission assembly and the rotating rod 300 stop rotating, locking the rotating rod 300 in the fallen position.

[0047] In other embodiments, the first limit position and the second limit position may be determined according to the actual maintenance needs. This application does not limit the first limit position and the second limit position.

[0048] In one embodiment, when the rotating rod 300 rotates to either the first or second limit position, the power maintenance fence is in either a maintenance state or a reset state, respectively. In the maintenance state, the rotating rod 300 is vertically erected; in the reset state, the rotating rod 300 is horizontally lowered. The power maintenance fence is communicatively connected to the anti-misoperation system platform and associated with the operation ticket, which helps to meet the anti-misoperation requirements. Upon receiving the communication signal from the anti-misoperation system platform, the power maintenance fence switches the rotating rod 300 to the first limit position for the unit interval requiring maintenance management. The power maintenance fence raises the rotating rod 300 to form a fenced area, which helps to avoid enclosing the wrong unit interval.

[0049] In one implementation, when the rotating rod 300 rotates to either the first or second extreme position, the power maintenance fence either encloses the energized unit interval or releases the enclosure of the unit interval, respectively. When the unit interval is energized, the anti-misoperation system platform cannot issue commands to control the rotating rod 300. The power maintenance fence is in position where the energized unit interval is enclosed, and the rotating rod 300 is erected to enclose the energized unit interval, preventing operators from accidentally entering the energized unit interval and improving safety. Before the unit interval is energized, the anti-misoperation system platform can send a signal to verify the status of the power maintenance fence. Only when the rotating rod 300 is erected and encloses the energized unit interval can a signal be sent allowing the unit interval to be energized. Before the rotating rod 300 falls horizontally, it is necessary to verify whether the unit interval is still energized. Only when the unit interval is de-energized can the rotating rod 300 fall horizontally, and the power maintenance fence releases the enclosure of the unit interval.

[0050] like Figure 8 As shown, the power maintenance fence also includes a movable mounting base 400, with a drive assembly 200 disposed inside the mounting base 400. The mounting base 400 can be placed directly on the ground, reducing the amount of construction work.

[0051] like Figure 8 As shown, the mounting base 400 also includes a cover 420 and a seat 430. The cover 420 is detachably disposed on the top surface of the seat 430 to open or close the seat 430. A receiving cavity is formed between the cover 420 and the seat 430 to accommodate the drive assembly 200. One side of the seat 430 includes a first through hole 410, through which a portion of the transmission assembly extends and is connected to the rotating rod 300. A first sealing structure 440 is also provided between the cover 420 and the seat 430, and the first sealing structure 440 includes a sealing strip disposed along the edge of the cover 420.

[0052] This utility model's technical solution features a movable mounting base 400, with a drive component 200 housed inside. The mounting base 400 can be placed directly on the ground or moved to different positions as needed. The drive component 200 drives the rotating rod 300 to stand upright, forming a fence without the need for digging, facilitating installation. Furthermore, the first sealing structure 440 of this utility model provides dust, rain, and water protection for the power maintenance fence, effectively preventing rainwater and dust from entering through the cover 420, making it suitable for harsh environments and extending its service life.

[0053] like Figures 7 to 8 As shown, the power maintenance fence also includes a second sealing structure 500, which is disposed in the first through hole 410 to seal the connection between the transmission component and the mounting base 400. By providing the second sealing structure 500, this utility model's technical solution makes the power maintenance fence dustproof, rainproof, and waterproof, helps ensure the long-term stable operation of the drive component 200, facilitates its application in harsh environments, and extends its service life.

[0054] like Figures 7 to 8 As shown, the second sealing structure 500 includes a sealing plate 510, a first sealing ring 520, and a second sealing ring 530.

[0055] The sealing plate 510 includes a first cover plate 511 and a second cover plate 512. The first cover plate 511 is disposed on the outer side of the seat 430, and the second cover plate 512 is located on the inner side of the seat 430 and is disposed corresponding to the first cover plate 511. Both the first cover plate 511 and the second cover plate 512 include a second through hole 513 that communicates with the first through hole 410. Part of the transmission component can pass through the first through hole 410 and the second through hole 513 to the outside of the seat 430. The first sealing ring 520 is disposed at the second through hole 513 of the first cover plate 511.

[0056] Furthermore, the first cover plate 511 also includes a mounting position for installing the second sealing ring 530. The mounting position is located near the side where the second cover plate 512 is located. The second sealing ring 530 is used to seal the connection between the first cover plate 511 and the second cover plate 512.

[0057] The present invention, by setting a sealing plate 510, a first sealing ring 520 and a second sealing ring 530, can not only ensure the normal rotation of the transmission component, but also help to prevent dust, rain and water, help to ensure the long-term stable operation of the drive component 200, help to be suitable for harsh environments and extend service life.

[0058] Preferably, the inner circumferential surfaces of the first sealing ring 520 and the second sealing ring 530 are matched with the outer circumferential surface of the transmission assembly to avoid affecting the rotation of the transmission assembly. Specifically, the first sealing ring 520 includes a plug seal, and the second sealing ring 530 includes an O-ring seal.

[0059] like Figure 3 as well as Figure 8 As shown, the rotating end of the rotating rod includes two opposing mounting walls 311, with a mounting groove 312 formed between the two mounting walls 311 for mounting a transmission component. The mounting walls 311 and the transmission component are connected by fasteners 313, enabling the transmission component to drive the rotating rod 300 to rotate. Specifically, the fasteners 313 are mounting screws, and both the mounting walls 311 and the transmission component have connecting holes that mate with the mounting screws. The rotating rod 300 and the transmission component are then securely connected by the mounting screws.

[0060] like Figures 9 to 10 As shown, the warning tape assembly 100 includes a housing 110, a warning tape, and a sensing component 120. The housing 110 is detachably connected to the mounting end 320 of the rotating rod 300, and the warning tape assembly 100 is detached from the mounting end 320 of the rotating rod 300 when the rotating rod 300 is lowered. The warning tape is coiled and retracted within the housing 110, which has an opening for the warning tape to be pulled out.

[0061] The sensing component 120 is disposed within the housing 110. The sensing component 120 includes a first sensing element 121 and a second sensing element 122. The first sensing element 121 is disposed on either side of the opening and is used to detect the stretching of the warning tape. The second sensing element 122 is disposed at the bottom of the housing 110 and is used to detect the connection between the housing 110 and the mounting end 320.

[0062] This utility model's technical solution involves setting up a warning tape assembly 100, which includes a warning tape and a sensing component 120. The warning tape extends out and connects with the adjacent power maintenance fence to form a clear safety boundary, effectively isolating the substation's maintenance area from live equipment, reducing the risk of accidentally entering dangerous areas, preventing operator misoperation, and thus improving the substation's safety management level.

[0063] By setting the first sensor 121, the tension state of the warning tape can be detected, and abnormal breakage or failure to return the warning tape to its proper position can be detected in a timely manner. By setting the second sensor 122, the connection between the housing 110 and the mounting end 320 can be detected, avoiding the failure of the fence due to loose connection, which helps to improve the safety monitoring capability.

[0064] like Figure 11As shown, the power maintenance fence also includes a control unit, which is communicatively connected to the maintenance system to drive or stop the rotation of the drive component 210, thereby driving or stopping the rotation of the rotating rod 300 driven by the drive transmission assembly. This utility model's technical solution, by connecting the control unit to the maintenance system, facilitates meeting error prevention requirements and linking it to operation tickets. The power maintenance fence can be operated on the unit intervals that need management, preventing the wrong area from being fenced off. When the unit interval is energized, it is impossible to issue a command to control the rotating rod 300 of the power maintenance fence to fall.

[0065] Specifically, the maintenance system can remotely or automatically control the start and stop of the drive component 210, and manipulate the transmission assembly to drive the rotating rod 300 to rotate. Furthermore, before power is applied, the status of the power maintenance fence can be checked, such as whether the rotating rod 300 is upright and whether the warning tape is in place. If safety conditions are not met, an early warning is issued and power is prohibited, ensuring operational safety and facilitating intelligent and automated management. Through the coordinated operation of the control unit, drive component 200, and limit component 260, the rotation and precise locking of the power maintenance fence are achieved, improving operational efficiency, meeting the needs of intelligent maintenance, and avoiding safety risks caused by human error.

[0066] This utility model's technical solution effectively isolates the maintenance area and energized equipment in a substation, forming a clear safety boundary, reducing the risk of accidental entry into dangerous areas, and preventing operator misoperation, thereby significantly improving the substation's safety management level. The power maintenance fence can be placed directly on the ground, and the rotating rod 300 is raised or lowered by the drive component 200, enabling rapid installation or dismantling in a short time, greatly reducing manual operation time and labor intensity, and improving work efficiency. During equipment inspection and maintenance, safety intervals can be quickly and conveniently set up to ensure the safety of operators without affecting normal workflow.
