[0002] High-voltage towers are trapezoidal or triangular tower-shaped buildings, usually 25 to 40 meters high, with steel frame structures. High-voltage towers are mostly built near power plants and distribution stations in the wild. They are important facilities for the power sector, which can overhead wires and play a role in protection and support. The design, manufacture, installation, maintenance and quality inspection of high-voltage towers are important guarantees for the operation and development of modern power systems.

[0003] Cylindrical climbing poles are installed on high-voltage towers to facilitate workers to step on the climbing poles step by step to reach the top of the high-voltage tower for maintenance. This operation process is considered high-altitude work, which is considered a high-risk operation. Therefore, workers who maintain high-voltage towers need to have relevant special operation certificates such as high-altitude climbing certificates. In order to prevent idle people from climbing high-voltage towers for no reason, warning signs are generally set up around high-voltage towers to warn passers-by not to climb.

DETAILED DESCRIPTION

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. 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 any creative efforts shall fall within the scope of protection of the present invention.

[0020] Example 1 Safety warning device for high voltage tower, reference Figures 1-4 The invention comprises a fixing base 100 and a fixing mechanism 200. The fixing base 100 has a positioning groove 101 on its rear wall, which is plugged into a high-voltage tower climbing pole. The fixing mechanism 200 is located at a position of the fixing base 100 relative to the positioning groove 101 and is used to connect with the high-voltage tower climbing pole.

[0021] Specifically, such as Figure 4 、 Figure 5 As shown, the fixing mechanism 200 includes a rotating plate 210, a rotating plate slot 220, and a rotating plate drive mechanism 230. The rotating plate 210 is rotatably connected to the fixing base 100; the rotating plate slots 220 are provided on either side of the positioning slot 101 and engage with the rotating plate 210 to accommodate the rotating plate 210; and the rotating plate drive mechanism 230 is in driving connection with the rotating plate 210 to drive the rotating plate to rotate. In this embodiment, the rotating plate 210 is a semi-circular ring structure, and the rotating plate slot 220 is a semi-circular ring groove adapted to the rotating plate 210. When the rotating plate 210 rotates, the rotating plate 210 can enter the rotating plate slot 220.

[0022] like Figure 6 、 Figure 7As shown, the rotating plate driving mechanism 230 includes a gear 231, a driving rod 232, and a driving rod insertion slot 234. The gear 231 is disposed in a chamber within the fixing base 100 and is rotatably connected to the fixing base 100. The rotating plate 210 is provided with a tooth groove 211, and the gear 231 is meshed with the tooth groove 211. During the rotation of the gear 231, the rotating plate 210 is driven to rotate. The driving rod 232 is plugged into and engaged with the gear 231 to drive the gear to rotate. The driving rod insertion slot 234 is provided on the side wall of the fixing base 100 and communicates with the chamber where the gear 231 is located, for inserting the driving rod 232.

[0023] To limit the position of the gear, a stopper 233 is slidably connected to the fixing base 100 near the connection between the gear 231 and the drive rod 232. Specifically, the stopper 233 is connected to the fixing base 100 via a spring 235. When the drive rod 232 is plugged into the gear 231, the drive rod 232 squeezes the stopper 233 into the fixing base 100, unlocking the gear 231, thereby allowing the gear 231 to rotate under the drive of the drive rod 232. After the drive rod 232 leaves the gear 231, the stopper 233 plugs into any recessed area on the outer wall of the gear 231, locking the gear 231 and preventing it from rotating.

[0024] As a further solution of this example, the stopper 233 includes an extrusion block 2331 and a clamping block 2332; the clamping block 2332 is arranged at one end close to the gear 231 and is located on the outside of the gear 231; the extrusion block 2331 is arranged on a side close to the drive rod insertion slot 234 and is located on the outside of the drive rod insertion slot 234; the distance between the extrusion block 2331 and the center axis of the gear 231 is smaller than the distance between the clamping block 2332 and the center axis of the gear 231.

[0025] In this embodiment, a spiral groove 2321 is defined in the drive rod 232. The gear 231 is rotatably connected to the fixed base 100 via a rotating shaft 2312. The gear 231, its rotating shaft 2312, and its central portion are all annular in structure, allowing the drive rod 232 to be inserted into the center of the gear 231. A guide block 2311 is provided on the inner wall of the gear 231, near one end of the drive rod insertion groove 234, and slidably engages with the spiral groove 2321. As the drive rod 232 moves within the gear 231, the spiral groove 2321 and the guide block 2311 cause the gear 231 to rotate.

[0026] To drive the stopper 233 to move, the insertion end of the drive rod 232 is formed with a beveled structure. The end of the stopper 233 closest to the drive rod insertion slot 234, namely the extrusion block 2331, is formed with a beveled surface that mates with the beveled structure of the drive rod 232. Before the drive rod 232 is inserted into the gear 231, the beveled surface at the front end of the drive rod 232 contacts the beveled surface of the extrusion block 2331. As the drive rod 232 is inserted, the drive rod 232 presses the extrusion block 2331 into the fixed seat, thereby disengaging the block 2332 from the gear 231 and unlocking the gear 231. After the drive rod 232 is inserted into the gear 231, the spiral groove 2321 on the drive rod 232 mates with the guide block 2311 on the inner wall of the gear 231. As the spiral groove 2321 presses the guide block 2311, the gear 231 rotates.

[0027] In order to adapt to climbing poles of different distances, the fixing seat 100 is provided with at least one set of sliders 102 and sliding grooves 103 cooperating with the sliders 102 . The sliders 102 are provided with positioning grooves 101 and fixing mechanisms 200 .

[0028] The working principle of the safety warning device applied to high-voltage power towers in this embodiment is as follows: like Figure 1 、 Figure 2 As shown, the staff can fix the device on the high-voltage tower climbing pole close to the ground, adjust the position of the slider 102, and make the distance between the positioning groove 101 opened on the slider 102 and the positioning groove 101 opened on the rear wall of the fixing seat 100 adapt to the distance between the two climbing poles of the high-voltage tower, so that the staff can accurately fix the device on the high-voltage tower climbing pole, and then use a single or multiple devices to completely block the lower high-voltage tower climbing pole, so that it cannot play the role of assisting in climbing the high-voltage tower. In addition, the expansion and retraction of the rotating plate 210 of the device are both realized by the driving rod 232 with a special structure. It is impossible for idle personnel to remove the restriction of the high-voltage tower climbing pole by simple means, which ensures to the greatest extent that idle personnel cannot easily climb up the high-voltage tower. A metal "No Climbing" four-character slogan can be set on the front wall of the fixing seat 100 by welding, so that the device can restrict the use of the climbing pole while also serving as a verbal warning to idle personnel. When fixing this device to a high-voltage tower climbing pole, the staff needs to first determine the position through the two positioning grooves 101, so that the two adjacent high-voltage tower climbing poles are respectively inserted into the two positioning grooves 101. The depth of the positioning groove 101 is greater than the radius of the high-voltage tower climbing pole, and the height of its open end is greater than or equal to the diameter of the high-voltage tower climbing pole. Under such a structure, the high-voltage tower climbing pole inserted into the positioning groove 101 can be limited, thereby completing the pre-fixation of this device to the high-voltage tower.

[0029] After pre-fixing, the staff can pull out the driving rod 232 from the side of the fixing seat 100. As the driving rod 232 is pulled out, the spiral groove 2321 on it will squeeze the guide block 2311. Since the guide block 2311 and the gear 231 are fixed to each other, the gear 231 will rotate during the withdrawal of the driving rod 232. Under the meshing of the gear 231 and the tooth groove 211 of the rotating plate 210, the rotating plate 210 will rotate out of the fixing seat 100 and the positioning plate 210 will be pulled out from the rear side. The open end of the groove 101 is closed, thereby enclosing the high-voltage tower climbing pole inside the positioning groove 101. The rotating plate 210 itself is a semi-circular arc structure, but it is not arranged on the same axis as the positioning groove 101. The axis position of the rotating plate 210 is closer to the front than the axis position of the positioning groove 101. This design is to ensure that the part exposed to the outside after the end of the rotating plate 210 is inserted into the positioning groove 101 does not constitute a half arc, thereby ensuring to the greatest extent that this device cannot provide a foothold for auxiliary climbing for idle personnel.

[0030] After the drive rod 232 pulls out of the gear 231, the inclined surface at the front end of the drive rod 232 separates from the inclined surface of the extrusion block 2331. Without the obstruction of the drive rod 232, the extrusion block 2331 is pushed out of the fixed seat 100 by the spring 235. The clamping block 2332 then inserts into the corresponding tooth groove on the outer wall of the gear 231, thereby restricting the rotation of the gear 231 and firmly binding the device to the high-voltage tower support frame and the climbing pole, thereby effectively preventing unauthorized climbing by unauthorized personnel. Only when the drive rod 232 is reinserted, the end of the drive rod 232 will use the inclined surface to squeeze the extrusion block 2331 and the clamping block 2332 back into the fixed seat 100, otherwise the gear 231 will not rotate.

[0031] When it is necessary to disassemble the device, it is only necessary to reinsert the drive rod 232. Under the squeezing of the spiral groove 2321 on the guide block 2311, the gear 231 drives the rotating plate 210 to rotate and retract it into the rotating plate groove 220, thereby releasing the restriction on the climbing pole. The staff only needs to carry the drive rod 232 to complete the locking and unlocking of the climbing pole by the device.

[0032] In order to ensure the safety of maintenance personnel, a bend or a stopper is generally provided at the end of the climbing pole. In this device, a groove for accommodating the bend or the stopper can be provided on the rear wall of the fixing seat.

[0033] Example 2 The difference between this embodiment and the first embodiment is that the structures of the driving rod 232 and the gear 231 are different. Specifically, in this embodiment, Figure 8As shown, the end of the driving rod 232 is mounted on the insert block 2325. The gear 231 is rotatably connected to the fixing base 100 via a rotating shaft 2312. The rotating shaft 2312 is a solid structure. The end of the rotating shaft 2312 near the driving rod insertion slot 234 is provided with a slot 2313 that cooperates with the insert block 2325. When the driving rod 232 is rotated, the rotating shaft 2312 drives the gear 231 to rotate.

[0034] To drive the stopper to move, in this embodiment, the drive rod 232 includes a first rod portion 2322 and a second rod portion 2323. The first rod portion 2322 and the second rod portion 2323 are coaxially located. The diameter of the first rod portion 2322 is larger than that of the second rod portion 2323. The first rod portion 2322 is transitioned through a truncated cone 2324. The end of the stopper 233 near the drive rod insertion slot 234, i.e., the extrusion block 2331, has an inclined surface that matches the curved surface of the truncated cone 2324. Before the insertion block 2325 at the end of the second rod portion 2323 contacts the rotating shaft 2312 of the gear 231, the truncated cone 2324 contacts the inclined surface of the extrusion block 2331. As the drive rod 232 continues to be inserted, the truncated cone 2324 presses the extrusion block 2331 toward the fixed base 100, thereby causing the locking block 2332 to separate from the gear 231 and unlock the gear 231. The insert block 2325 at the end of the second rod portion 2323 is inserted into the slot 2313 on the rotating shaft 2312 , and the driving rod 232 is rotated, thereby driving the gear 231 to rotate via the rotating shaft 2312 .

[0035] The usage process of the driving rod 232 of this embodiment is as follows: when the device needs to be fixed on a climbing pole, the driving rod 232 is inserted into the driving rod insertion groove 234. During the insertion process, the round table 2324 squeezes the extrusion block 2331 toward the fixing seat 100, so that the locking block 2332 leaves the gear 231, thereby unlocking the gear 231. Then, the driving rod 232 continues to be inserted, so that the insert block 2325 at the end of the second rod portion 2323 is inserted into the slot 2313 on the rotating shaft 2312, and the driving rod 232 is rotated, and the gear 231 is driven to rotate through the rotating shaft 2312, thereby rotating the rotating plate 210 out of the fixing seat 100, and closing the open end of the positioning groove 101 from the rear side, and then the driving rod 232 is pulled out from the driving rod insertion slot 234. When the driving rod 232 is pulled out, the squeezing block 2331 is no longer squeezed by the outer wall of the driving rod 232. Under the action of the spring 235, the squeezing block 2331 and the clamping block 2332 are pushed out of the fixing seat 100, and the clamping block 2332 will be inserted into the corresponding tooth groove on the outer wall of the gear 231, thereby limiting the rotation of the gear 231.

[0036] When it is necessary to release the restriction of the climbing pole by the device, the driving rod 232 is simply inserted again and rotated to allow the rotating plate 210 to enter the rotating plate groove 220, thereby releasing the restriction of the rotating plate 210 on the climbing pole.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
