Technical Field

[0001] The present invention relates to the technical field of safety fences, in particular to a movable, quickly deployed safety fence for a substation. Background Art

[0002] Safety fences are primarily used to restrict and prevent activities within a specific range of power sites, thereby eliminating or mitigating potential safety hazards. Depending on the location of use, safety fences can be classified into various types, including fences, fences, and warning tapes. For example, a metal frame safety fence is used outside the GIS high-voltage switch room in a substation to prevent unauthorized personnel from entering the GIS high-voltage switch room, thereby increasing the safety of the GIS high-voltage switch room.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1 See also Figure 1-8 A movable substation quick-deployment safety fence includes two support columns 1, the bottom end of the support column 1 is fixedly connected to a positioning mechanism 4, the bottom of the positioning mechanism 4 is provided with a moving mechanism 5, and the top of the support column 1 is provided with a protective mechanism 6.

[0022] A protective frame 2 is fixedly connected between the two support columns 1 .

[0023] There are two connecting frames 401, and the upper surfaces of the connecting frames 401 are fixedly connected to the bottom surfaces of the two support columns 1 respectively. The front and rear sides of the interior of the connecting frames 401 are slidably connected with telescopic cylinders 403. The interior of each telescopic cylinder 403 is slidably connected with a telescopic plate 404. The head end of each telescopic plate 404 is threadedly connected to a threaded rod 405 in the vertical direction, and the bottom end of the threaded rod 405 is rotatably connected to a support plate 406.

[0024] Sliding frames 501 are fixed on the left and right sides of the lower end of the connecting frame 401 respectively. The sliding frames 501 are horizontally arranged in the left and right directions. The lower end of the sliding frame 501 is installed with a connecting seat 505 through a moving mechanism. The lower end of the connecting seat 505 is rotatably installed with a roller 506. The moving mechanism drives the connecting seat 505 to move up and down in the vertical direction.

[0025] The protective frame 2 has an opening inside, with a protective door 3 movably hinged at the opening. Four support blocks 402 are fixedly connected to the bottom surfaces of the two connecting frames 401. The protective frame 2 not only connects the two support columns 1, increasing the connection between them, but also ensures the proper functioning of the isolation and protection system. With the protective door 3 open, workers can easily pass through the protective frame 2 into the substation GIS high-voltage switch room for inspections or work. The support blocks 402 prevent the entire safety fence from contacting the ground through the support blocks 402 unless the threaded rod 405 is rotated to bring the support plate 406 into contact with the ground, thus preventing damage to the equipment.

[0026] The telescopic cylinder 403 and the telescopic plate 404 are fixed by the positioning mechanism when they slide outward to the extended state. The positioning mechanism 4 includes a clamping groove 407 respectively provided on the inner top wall of the connecting frame 401 and the inner top wall of the telescopic cylinder 403. The interior of the telescopic cylinder 403 and the interior of the telescopic plate 404 are both slidably connected with a clamping frame 408 in the vertical direction. The inner bottom wall of the telescopic cylinder 403 and the inner bottom wall of the telescopic plate 404 are fixedly connected with two compression springs 409. The top ends of the compression springs 409 are fixedly connected to the bottom surfaces of the corresponding clamping frames 408. When the compression springs 409 are in a free state, the top ends of the clamping frames 408 are inserted into the inner ends of the corresponding clamping grooves 407. Each telescopic cylinder 403 and each telescopic plate 404 are vertically slidably connected to a push-on frame 410. One side of each push-on frame 410 is fixedly connected to one side of the corresponding clip-on frame 408. Two reinforcing ribs 411 are fixedly connected to the upper surface of the connecting frame 401. One side of each reinforcing rib 411 is fixedly connected to the outer surface of the support column 1. The push-on frame 410 moves with the movement of the clip-on frame 408. Pressing the push-on frame 410 downward can drive the clip-on frame 408 downward to disengage from the clip-on slot 407, thereby unlocking the clip-on frame 408 and making it easier to operate. The reinforcing ribs 411 can increase the connection strength between the connecting frame 401 and the support column 1, preventing the connecting frame 401 from loosening from the support column 1.

[0027] The bottom end of each threaded rod 405 is fixedly connected to an anti-slip ring 412, and each anti-slip ring 412 is rotatably connected to the inside of the support plate 406. The anti-slip ring 412 can limit the position of the threaded rod 405 inside the support plate 406 without affecting the smooth rotation of the threaded rod 405, ensuring that the threaded rod 405 can smoothly drive the support plate 406 to move up and down.

[0028] The inner bottom wall of each telescopic cylinder 403 and the inner bottom wall of each telescopic plate 404 are fixedly connected with a telescopic rod 413 in the vertical direction. Each telescopic rod 413 is arranged inside the corresponding compression spring 409. The telescopic end of each telescopic rod 413 is fixedly connected to the bottom surface of the corresponding clamping frame 408. The telescopic rod 413 can prevent the compression spring 409 from deflecting, thereby increasing the reliability of the use of the compression spring 409.

[0029] The specific implementation method of this embodiment is as follows: when the support column 1, protective frame 2 and protective door 3 need to be arranged outside the substation GIS high-voltage switch room for isolation protection, it is only necessary to pull the telescopic cylinder 403 outward from the inside of the connecting frame 401, and at the same time pull the telescopic plate 404 out of the inside of the telescopic cylinder 403 until the telescopic cylinder 403 and the telescopic plate 404 slide outward until the clamping frame 408 is perpendicular to the clamping groove 407, and the elastic force provided by the compression spring 409 cooperates with the limit of the telescopic rod 413 to simultaneously push the clamping frame 408 and the pressing frame 410 upward until the top of the clamping frame 408 is clamped into the inside of the clamping groove 407. At this time, the position of the telescopic cylinder 403 and the telescopic plate 404 after being expanded outward can be fixed, and then the threaded rod 405 is manually rotated to cooperate with the threaded connection relationship between the threaded rod 405 and the telescopic plate 404, and the limit of the anti-slip ring 412, so that the threaded rod 405 can drive the support The plate 406 moves downward until the support plate 406 contacts the ground. At this time, the support column 1 and the protective frame 2 can be positioned by the support plate 406, and the installation and arrangement of the support column 1 and the protective frame 2 are completed. When the substation safety fence protects and encloses the GIS high-voltage switch room, there is no need to use bolts to fix the safety fence to the ground, which increases the convenience of installation and arrangement of the substation safety fence and reduces the workload of the staff. At the same time, it will not cause damage to the ground outside the substation GIS high-voltage switch room, thereby improving the arrangement efficiency of the safety fence. When the device needs to be folded up, it is only necessary to rotate the threaded rod 405 in the opposite direction to fold up the support plate 406, and then press the pressing frame 410 downward to allow the pressing frame 410 to drive the clamping frame 408 to move downward until it is disengaged from the clamping groove 407. At this time, the telescopic cylinder 403 can be retracted into the connecting frame 401, and the telescopic plate 404 will also be retracted into the telescopic cylinder 403.

[0030] Example 2 See also Figure 1-8The moving mechanism 5 includes two sliding seats 502 installed at the bottom of the sliding frame 501 in a sliding manner along the left and right directions. The interior of the sliding frame 501 is rotatably connected with a bidirectional screw 503. The axis of the bidirectional screw 503 is horizontally arranged along the left and right directions. The thread rotation directions of the two thread segments of the bidirectional screw 503 are opposite. The thread segments of the bidirectional screw 503 on the sliding seat 502 and the corresponding side are threadedly connected. The inner wall of the sliding frame 501 is movably hinged with a movable plate 504. The end of the movable plate 504 away from the sliding seat 502 is movably hinged with the connecting seat 505. The left and right sides of the bottom surface of the connecting base 505 are fixedly connected to rollers 506, one end of the bidirectional screw 503 is coaxially connected to a first bevel gear 507, and the front and rear ends of the outer end of the connecting frame 401 are respectively mounted with stabilizing frames 510. The front and rear ends of the rotating rod 508 are rotatably mounted in the corresponding stabilizing frames 510 on the same side. The axis of the rotating rod 508 is arranged horizontally along the front-to-back direction. The front and rear ends of the rotating rod 508 are respectively fixedly connected to second bevel gears 509, which mesh with the corresponding first bevel gear 507 on the same side. The stabilizing frames 510 can limit the position of the rotating rod 508, increase the rotational stability of the rotating rod 508, and allow the rotating rod 508 to smoothly drive the second bevel gear 509 to rotate.

[0031] The head end of the rotating rod 508 is fixedly connected to a rotating plate 511, and the rotating plate 511 is fixedly connected to a handle 512. The axis of the handle 512 is parallel to the axis of the rotating rod 508. Manually holding the handle 512 and cooperating with the rotating plate 511 can facilitate the staff to manually rotate the rotating rod 508, thereby increasing the convenience of rotating the rotating rod 508.

[0032] The specific implementation method of this embodiment is as follows: when it is necessary to move the position of the support column 1 and the protective frame 2 and fine-tune the installation position of the safety fence, it is only necessary to manually hold the handle 512 and cooperate with the rotating plate 511 to rotate the rotating rod 508. The engagement of the first bevel gear 507 and the second bevel gear 509 and the limit of the stabilizing frame 510 can drive the bidirectional screw 503 to rotate. When the bidirectional screw 503 rotates, the bidirectional thread on the bidirectional screw 503 and the limit of the sliding frame 501 on the sliding seat 502 can drive the sliding seat 502 to slide closer to each other inside the sliding frame 501. As the sliding seats 502 approach each other, the movable plate 504 can push the connecting seat 505 and the roller frame 506 to move downward until the roller frame 506 contacts the ground, so that the support plate 406 and the support block 402 are both off the ground. Then, the rolling of the roller frame 506 can quickly move the position of the safety fence, further increasing the convenience of safety fence arrangement and position adjustment.

[0033] Example 3 See also Figure 1-8The protective mechanism 6 includes two telescopic frames 601, which are respectively slidably inserted into the interior of the corresponding support column 1 on the same side in the vertical direction. The inner bottom wall of the support column 1 is fixedly connected to a multi-stage electric push rod 602 in the vertical direction. The telescopic end of the multi-stage electric push rod 602 is fixedly connected to the bottom surface of the telescopic frame 601 on the same side. The internal rotation of the telescopic frame 601 is connected to a winding rod 611. The axis of the winding rod 611 is set in the vertical direction. The upper and lower end surfaces of the winding rod 611 are elastically connected to the inner wall of the telescopic frame 601 through a spring spring 603. The outer surface of the reeling rod 611 is fixedly connected to a protective net 604. The sides of the two protective nets 604 that are close to each other are fixedly connected to a docking plate 605. The sides of the docking plates 605 that are close to each other are fixedly connected to three positioning brackets 606. The six positioning brackets 606 are internally engaged with a positioning pin 607. The inner side walls of the two support columns 1 are each provided with two sliding grooves 608. The two sides of each telescopic frame 601 are fixedly connected to two auxiliary blocks 609, each of which is slidably connected to the inside of the sliding groove 608. The auxiliary blocks 609 slide in the sliding groove 608 to limit the sliding position of the telescopic frame 601 inside the support column 1, preventing the telescopic frame 601 from loosening from the support column 1 and improving the sliding safety of the telescopic frame 601.

[0034] The bottom surface of the telescopic frame 601 is fixedly connected with a reinforcement ring 610, and the inner wall of the inner circle of the reinforcement ring 610 is fixedly connected to the outer surface of the telescopic end of the multi-stage electric push rod 602 corresponding to the same side. The reinforcement ring 610 can increase the connection firmness between the multi-stage electric push rod 602 and the telescopic frame 601, making it difficult for the multi-stage electric push rod 602 to loosen from the telescopic frame 601, thereby ensuring the matching strength between the multi-stage electric push rod 602 and the telescopic frame 601.

[0035] The specific implementation of this embodiment is as follows: when it is necessary to install the upper enclosure of the safety fence, it is only necessary to use the power provided by the multi-stage electric push rod 602 to cooperate with the support column 1 and the auxiliary block 609 to slide inside the sliding groove 608 to limit the telescopic frame 601, so as to push the telescopic frame 601 to move upward, and then manually pull the docking plate 605 outward to drive the protective net 604 wound on the winding rod 611 to be pulled out from the telescopic frame 601. As the protective net 604 is pulled out, the protective net 604 can drive the winding rod 611 to rotate. When the winding rod 611 rotates, it can drive the clockwork spring 603 to accumulate elastic force. When the protective net 604 is pulled outward until the positioning hole on the positioning frame 606 is completely vertical, the positioning pin 607 is inserted into the positioning frame 606 can fix the position of the protective net 604, so that the upper enclosure of the substation safety fence does not need to be installed and fixed with bolts, which improves the installation convenience of the upper enclosure of the substation safety fence and further increases the overall layout convenience of the safety fence. When the protective net 604 needs to be folded up, it is only necessary to pull out the positioning pin 607 from the inside of the positioning frame 606 to release the limit of the docking plate 605 and the protective net 604. At this time, the elastic force accumulated by the clockwork spring 603 can be used to drive the winding rod 611 to rotate in the opposite direction, and the protective net 604 can be rewound onto the winding rod 611. Then the multi-stage electric push rod 602 is retracted to drive the telescopic frame 601 to retract into the support column 1, and the folding and storage of the protective net 604 can be completed.

[0036] The working principle of the present invention is as follows: when it is necessary to arrange the support column 1, the protective frame 2 and the protective door 3 outside the GIS high-voltage switch room of the substation for isolation protection, it is only necessary to pull the telescopic cylinder 403 outward from the inside of the connecting frame 401, and at the same time pull the telescopic plate 404 out from the inside of the telescopic cylinder 403, until the telescopic cylinder 403 and the telescopic plate 404 slide outward until the clamping frame 408 is perpendicular to the clamping groove 407, and the elastic force provided by the compression spring 409 cooperates with the limit of the telescopic rod 413 to simultaneously push the clamping frame 408 and the pressing frame 410 upward until the top end of the clamping frame 408 is clamped into the inside of the clamping groove 407. At this time, the position of the telescopic cylinder 403 and the telescopic plate 404 after being expanded outward can be fixed, and then the threaded rod 405 can be manually rotated. By coordinating the threaded connection between the threaded rod 405 and the telescopic plate 404 and the limiting position of the anti-slip ring 412, the threaded rod 405 can drive the support plate 406 to move downward until the support plate 406 contacts the ground. At this time, the support column 1 and the protective frame 2 can be positioned by the support plate 406 to complete the installation and arrangement of the support column 1 and the protective frame 2. When the substation safety fence protects and encloses the GIS high-voltage switch room, there is no need to use bolts to fix the safety fence to the ground, which increases the convenience of installation and arrangement of the substation safety fence and reduces the workload of the staff. At the same time, it will not cause damage to the ground outside the substation GIS high-voltage switch room, thereby improving the layout efficiency of the safety fence. When the device needs to be retracted, it is only necessary to rotate the threaded rod 4 in the opposite direction. 05 Fold up the support plate 406, then press the pressing frame 410 downwards, so that the pressing frame 410 drives the clamping frame 408 to move downwards until it disengages from the clamping slot 407. At this time, the telescopic cylinder 403 can be retracted into the connecting frame 401, and the telescopic plate 404 will also be retracted into the telescopic cylinder 403. When it is necessary to move the position of the support column 1 and the protective frame 2 to fine-tune the installation position of the safety fence, it is only necessary to manually hold the handle 512 and cooperate with the rotating plate 511 to rotate the rotating rod 508. The engagement of the first bevel gear 507 and the second bevel gear 509 with the limit of the stable frame 510 can drive the bidirectional screw 503 to rotate. When the bidirectional screw 503 rotates, it cooperates with the bidirectional thread on the bidirectional screw 503 and the sliding frame 501 to the sliding seat The limit of 502 can drive the sliding seat 502 to slide in a mutually approaching manner inside the sliding frame 501. As the sliding seats 502 approach each other, the connecting seat 505 and the roller frame 506 can be pushed downward by the movable plate 504 until the roller frame 506 contacts the ground, so that the support plate 406 and the support block 402 are both off the ground. Then, the position of the safety fence can be quickly moved by the rolling of the roller frame 506, which further increases the convenience of arranging and adjusting the position of the safety fence. When the upper enclosure of the safety fence needs to be installed, it is only necessary to use the power provided by the multi-stage electric push rod 602 to cooperate with the support column 1 and the auxiliary block 609 to slide in the sliding groove 608 to limit the telescopic frame 601, which can push the telescopic frame 601 to move upward.Then manually pull the docking plate 605 outwards, which can drive the protective net 604 rolled up on the reeling rod 611 to be pulled out from the telescopic frame 601. As the protective net 604 is pulled out, the protective net 604 can drive the reeling rod 611 to rotate. When the reeling rod 611 rotates, it can drive the clockwork spring 603 to accumulate elastic force. When the protective net 604 is pulled outwards until the positioning hole on the positioning frame 606 is completely vertical, the positioning pin 607 is inserted into the positioning frame 606 to fix the position of the protective net 604, so that the upper enclosure of the substation safety fence does not need to be installed and fixed with bolts, which is convenient for installation. This improves the installation convenience of the upper enclosure of the substation safety fence and further increases the convenience of the overall layout of the safety fence. When the protective net 604 needs to be retracted, the positioning pin 607 is simply pulled out from the inside of the positioning frame 606 to release the limit of the docking plate 605 and the protective net 604. At this time, the accumulated elastic force of the spring 603 can drive the reeling rod 611 to rotate in the opposite direction, rewinding the protective net 604 onto the reeling rod 611.
