Description

Technical Field

[0001] This invention relates to the field of power transmission safety protection component installation technology, specifically a power transmission safety protection component and its installation method. Background Technology

[0002] In power transmission lines, high-voltage surge arresters are used to protect electrical equipment from high transient overvoltages during lightning strikes and to limit follow current time. Under the influence of overvoltage and high current, high-voltage surge arresters exhibit low resistance, thus limiting the residual voltage across the arrester and protecting the electrical equipment. However, when installing high-voltage surge arresters on the top of power poles in rugged mountainous areas inaccessible by aerial work platforms, manual handling is often required, hindering quick installation and removal and making replacement inconvenient.

[0003] To address the aforementioned issues, Chinese invention patent CN112736829B proposes a hybrid installation structure for surge arresters. This patent utilizes a limiting seat. Inside the limiting seat, limiting blocks move forward and backward on opposite sides under the action of springs, causing their slots to engage with the outer side of a limiting rod, thus restricting the lateral displacement of the limiting rod. A first fixing seat is secured by the limiting rod. During surge arrester installation, the first fixing seat and limiting rod are placed outside the surge arrester. The limiting rod is then passed through a baffle and a limiting hole, and the first gasket is pressed down, causing the limiting blocks to engage the limiting rod, thus completing the surge arrester installation. When the surge arrester needs to be removed, the two limiting blocks can be moved out of the limiting slots using an operating rod, and then the first fixing seat can be pulled to the left to remove the surge arrester, thereby facilitating the removal and installation of the surge arrester.

[0004] However, high-voltage surge arresters often need to maintain a certain posture during installation, and the posture of high-voltage surge arresters varies in different installation environments. This patent can only adjust the distance between the tower and the surge arrester, but cannot adjust the posture of the high-voltage surge arrester.

[0005] In reality, high-voltage surge arresters also need to be installed on the top of utility poles in rugged mountainous areas where ladder trucks cannot reach. In such cases, it is often necessary for people to manually climb to the top of the utility pole to install the high-voltage surge arrester. This installation method is time-consuming and labor-intensive, and there is a risk that the high-voltage surge arrester will fall and be damaged. Summary of the Invention

[0042] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0043] See Figure 1 and Figure 3A power transmission safety protection component includes an adjustable-position integrated surge arrester 1 and a climbing device 2 for installing the integrated surge arrester 1. The climbing device 2 includes a climbing frame 21, a climbing assembly 22, a climbing spring 23, a pushing assembly 24, a support arm 25, and a bracket 26. Two support arms 25 are provided, one fixedly mounted on the top front side of the climbing frame 21, and the other slidingly mounted on the middle front side of the climbing frame 21. The climbing assembly 22 is hinged to the front of each support arm 25. A climbing spring 23 is provided between the sliding support arm 25 and the bottom of the climbing frame 21, and a pushing assembly 24 is hinged to the lower part of the sliding climbing assembly 22. A bracket 26 is installed on the top of the climbing frame 21. A stud 261 is provided on the upper part of the bracket 26. When the integrated surge arrester 1 needs to be installed, the lower support arm 25 is first pushed downwards and the climbing assembly 24 is compressed. The spring 23 is raised, and then the position of the lower support arm 25 is locked. The climbing assembly 22 is then fitted onto the outside of the utility pole. Next, the integrated surge arrester 1 is connected to the upper part of the bracket 26. Finally, as the worker climbs the utility pole, they push the pushing assembly 24 upwards, which in turn moves the entire climbing device 2 upwards, thereby lifting the integrated surge arrester 1. When the climbing device 2 reaches an obstacle in the middle of the utility pole, the two climbing assemblies 22 rise sequentially, allowing the climbing device 2 to cross the obstacle and reach the top of the utility pole, thus installing the integrated surge arrester 1 at the top of the pole. Finally, the attitude of the integrated surge arrester 1 is adjusted to adapt to the current installation environment requirements. This invention assists workers in lifting and installing the integrated surge arrester 1 to the top of the utility pole, thereby improving installation efficiency; and allows the adjustable integrated surge arrester 1 to adapt to different installation attitude requirements.

[0044] See Figures 1-4 and Figures 8-11The climbing assembly 22 includes a rotating ring 221, a locking sleeve 222, a wheel frame 223, a climbing wheel 224, an adjusting component 225, a backstop component 226, and a climbing spring 227. Two rotating rings 221 are provided, symmetrically arranged left and right. The rear parts of the two rotating rings 221 are respectively hinged to the left and right sides of the support arm 25. Locking sleeves 222 are slidably inserted into the rotating rings 221 at equal intervals along their circumference. The interior of the locking sleeve 222 is close to the center of the rotating ring 221. A wheel frame 223 is rotatably mounted on one side of the rotating ring 221; an adjusting component 225 is slidably inserted inside the wheel frame 223 on the side away from the center of the rotating ring 221; the adjusting component 225 is located on the side of the wheel frame 223 away from the center of the rotating ring 221; anti-reverse components 226 are rotatably mounted at equal intervals along the circumference of the rotating ring 221; a climbing spring 227 is provided between the locking sleeve 222 and the inner wall of the rotating ring 221; a climbing wheel 224 is rotatably mounted on the side of the wheel frame 223 near the center of the rotating ring 221; when integrated When lightning arrester 1 needs to be installed, the rotating ring 221 is fitted onto the outside of the utility pole. The locking sleeve 222 moves towards the utility pole under the elastic force of the climbing spring 227. The locking sleeve 222 drives the wheel frame 223 to move synchronously until the climbing wheel 224 abuts against the outside of the utility pole. The anti-reverse component 226 fixes the direction of movement of the locking sleeve 222, ensuring that the locking sleeve 222 can only move towards the utility pole. As the climbing assembly 22 rises, the diameter of the utility pole decreases, due to the wheel frame 22... 3. Driven by the climbing spring 227, the climbing wheel 224 is pressed against the outside of the utility pole. At the same time, under the action of the anti-reverse component 226, it cannot move to the outside of the utility pole, so that the rotating ring 221 can only move towards the top of the utility pole. The climbing component 22 is used to limit the movement direction of the climbing device 2, so that it can only move towards the top of the utility pole, thereby assisting the worker to lift the integrated surge arrester 1 to the top of the utility pole, saving the worker's physical strength, simplifying the worker's operation, and further improving the installation efficiency.

[0045] See Figure 8 and Figure 10 The two rotating rings 221, hinged to the same support arm 25, are combined into a ring structure and fixed in position by a pin hole. When the rotating rings 221 are fitted onto the outside of the utility pole, the support arm 25 is moved to the rear of the utility pole, and then the two rotating rings 221 are rotated to fit onto the outside of the utility pole. Finally, locking pins are inserted simultaneously into the front of the two rotating rings 221, thereby fixing the position of the rotating rings 221 on the outside of the utility pole. The rotating rings 221 are used to fix the climbing device 2 on the outside of the utility pole so that the climbing device 2 can climb up the utility pole, thereby assisting the workers in the installation work.

[0046] See Figure 3 and Figure 8The pushing assembly 24 includes a retaining ring 241, a pushing handle 242, a retaining spring 243, and a retaining block 244. Two retaining rings 241 are provided; each retaining ring 241 is hinged to the lower side of two rotating rings 221 located at the bottom. A retaining spring 243 is provided between the upper part of the retaining rings 241 on the side furthest from each other and the rotating rings 221. A pushing handle 242 is provided on the side of the retaining rings 241 furthest from each other, and retaining blocks 244 are provided at equal intervals along the circumference of the right side of each retaining ring 241. A spring guide post is provided between the retaining block 244 and the retaining ring 241. When the climbing device 2 needs to move upward, the worker holds the pushing handle 242 and pushes it upward. 2. The clamping ring 241 rotates and compresses the clamping spring 243. The clamping ring 241 causes the clamping block 244 to disengage from the outer surface of the utility pole, thereby causing the clamping ring 241 to drive the rotating ring 221 to move upward. When the worker continues to climb, the push handle 242 removes the external force. The elastic force of the clamping spring 243 causes the clamping ring 241 to rotate until the clamping block 244 presses against the outside of the utility pole, thereby further fixing the position of the climbing device 2 when the worker climbs. The push component 24 is used to further fix the position of the climbing device 2 during the gap when the climbing device 2 rises, thereby improving the stability of the climbing device 2 when climbing and avoiding the risk of the integrated surge arrester 1 falling and being damaged.

[0047] See Figure 4 , Figure 8 , Figure 11 and Figure 12The locking sleeve 222 has slots evenly spaced along its length on the side near the anti-reverse member 226 for the anti-reverse member 226 to engage; a tension spring is provided between the adjusting member 225 and the wheel frame 223; a locking block is provided on the side of the adjusting member 225 near the locking sleeve 222; the locking sleeve 222 has two locking slots spaced 90° apart at the position of the locking block; when the locking sleeve 222 moves toward the utility pole, the slots on the outside of the locking sleeve 222 pass through the anti-reverse member 226 in sequence; when the locking sleeve 222 stops moving, the anti-reverse member 226 moves to the nearest slot, thereby locking the position of the locking sleeve 222; when the climbing device 2 needs to temporarily stop or needs to rotate around the utility pole, the adjusting member 225 is pulled away from the utility pole until the locking block is completely disengaged from the locking slot. The lifting device 2 is then rotated 90° by adjusting the adjusting member 225, which in turn rotates the wheel frame 223 90° synchronously. The locking block is then inserted into another slot, rotating the wheel frame 223 90° and locking it in place. This ensures the axis of the climbing wheel 224 is parallel to the axis of the utility pole, allowing the climbing device 2 to rotate around the utility pole and locking it at a certain height on the pole for easy installation of the integrated surge arrester 1. The locking sleeve 222 keeps the climbing wheel 224 pressed against the outside of the utility pole, thus restricting the direction of movement of the climbing device 2. The adjusting member 225 rotates the wheel frame 223, allowing the climbing device 2 to rotate around the utility pole for easy installation of the integrated surge arrester 1, thus increasing the practicality of the invention.

[0048] See Figure 8 and Figure 11 The anti-reverse component 226 has an inclined surface on the side near the locking sleeve 222, facing the center of the moving rotating ring 221. When the climbing device 2 rises, the locking sleeve 222, pushed by the climbing spring 227, engages with the inclined surface of the anti-reverse component 226, pushing the anti-reverse component 226 away from the locking sleeve 222. When the climbing device 2 stops, the anti-reverse component 226 automatically inserts into the corresponding slot under its own elastic force, thereby preventing the locking sleeve 222 from moving away from the utility pole. The anti-reverse component 226 is used to limit the movement direction of the locking sleeve 222, so that the climbing device 2 can only move upward, thus assisting the lifting of the integrated surge arrester 1. This facilitates the operation of workers and improves the efficiency of installation.

[0049] See Figure 3 , Figure 8 and Figure 9A positioning pin 251 is slidably inserted into the rear of the sliding support arm 25; a positioning spring 252 is provided between the positioning pin 251 and the support arm 25; a linkage frame 254 is installed at the rear of the positioning pin 251; symmetrical unlocking arms 253 are provided at the front ends of the left and right sides of the linkage frame 254 for pushing the corresponding rotating ring 221 backward; when the climbing device 2 climbs to the position of the obstacle in the middle of the utility pole, the upper rotating ring 221 is opened, and then the pushing component 24 is pushed upward until the upper climbing component 22 passes over the obstacle. After that, the upper rotating ring 221 is put back on the outside of the utility pole, and then the lower rotating ring 221 is opened. When the lower rotating ring 221 is opened, the unlocking arm 253 is pushed backward. The unlocking arm 253 drives the positioning pin 251 to move backward through the linkage frame 254 until it exits from inside the climbing frame 21. Then, the elastic force of the climbing spring 23 pushes the lower support arm 25 upward. The lower support arm 25 drives the climbing component 22 at its front to move upward to pass over the obstacle. Then, the rotating ring 221 at the lower part is once again sleeved and locked on the outside of the utility pole, so that the climbing device 2 can pass over the obstacle and continue to climb. The positioning pin 251 is used to lock the climbing spring 23 in the pre-compressed position in the initial state, so that the climbing spring 23 can push the lower climbing component 22 over the obstacle at the obstacle position, thereby enabling the climbing device 2 to pass over the obstacle and increasing the applicability of the present invention.

[0050] See Figure 3 , Figure 8 and Figure 9 The climbing frame 21 is provided with a locking hole at the position corresponding to the positioning pin 251; the climbing spring 23 is compressed to the pre-tight position, and then the positioning pin 251 is automatically inserted into the locking hole under the elastic force of the positioning spring 252 to lock the state of the climbing spring 23; the positioning pin 251 is used to cooperate with the locking hole to keep the climbing spring 23 in the pre-tight state, so as to facilitate the auxiliary lifting of the lower climbing component 22 at the position of the obstacle.

[0051] See Figure 1 and Figures 5-7The integrated surge arrester 1 includes a surge arrester body 11, a surge arrester base 12, a first support arm 13, a second support arm 14, a fixed support arm 15, and a rotating sleeve 16. The surge arrester base 12 is fixedly sleeved on the lower part of the surge arrester body 11. The first support arm 13 is hinged to the right end of the surge arrester base 12. The second support arm 14 is hinged to the right end of the first support arm 13. The fixed support arm 15 is hinged to the right end of the second support arm 14. The rotating sleeve 16 is rotatably mounted on the lower part of the surge arrester base 12. The inner wall of the rotating sleeve 16 is threaded. When the integrated surge arrester 1 is raised to the installation position, the fixed support arm is secured by bolts. The right end of 15 is installed in the designated position. Then, the rotating sleeve 16 is rotated to remove the surge arrester body 11 from the bracket 26. Then, by rotating and adjusting the angle of the surge arrester base 12, the first support arm 13 and the second support arm 14, the surge arrester body 11 is adjusted to the required posture. Then, the positions of the surge arrester base 12, the first support arm 13 and the second support arm 14 are fixed, thereby fixing the surge arrester body 11 in the required position. The integrated surge arrester 1 is used to adaptively adjust the posture of the surge arrester body 11 so that it can be installed quickly and adapt to different installation requirements.

[0052] See Figure 6 The surge arrester base 12, first support arm 13, second support arm 14 and fixed support arm 15 are fixed in position by means of pin holes; the pin holes between the surge arrester base 12, first support arm 13, second support arm 14 and fixed support arm 15 are used to quickly lock the surge arrester body 11, which greatly reduces installation time and improves installation efficiency.

[0053] See Figure 13 Furthermore, this invention also provides a method for installing a power transmission safety protection component, the specific steps of which are as follows:

[0054] First, push down the lower support arm 25 and compress the climbing spring 23. The lower support arm 25 drives the lower climbing component 22 to move down to the position where the positioning pin 251 is located in the locking hole. Then, the positioning pin 251 is automatically inserted into the locking hole under the elastic force of the positioning spring 252, keeping the climbing spring 23 in the pre-tight state.

[0055] The second step involves moving the support arm 25 to the rear of the utility pole, then rotating the two rotating rings 221 to fit onto the outside of the utility pole. Finally, locking pins are inserted simultaneously into the front of the two rotating rings 221 to fix their positions on the outside of the utility pole. Under the elastic force of the climbing spring 227, the locking sleeve 222 moves towards the utility pole, causing the climbing wheel 224 to move synchronously to press against the outside of the utility pole. The anti-reverse component 226 automatically inserts into the corresponding slot under its own elastic force, thereby preventing the locking sleeve 222 from moving away from the utility pole.

[0056] Third, the worker pushes the handle 242 upwards, causing the clamping ring 241 to rotate and compress the clamping spring 243. The clamping ring 241 causes the clamping block 244 to disengage from the outer surface of the utility pole, thereby causing the clamping ring 241 to move the rotating ring 221 upwards. When the rotating ring 221 moves upwards, the locking sleeve 222 engages with the inclined surface of the anti-reverse component 226 under the push of the climbing spring 227, pushing the anti-reverse component 226 away from the locking sleeve 222. When the worker moves upwards, the external force of the push handle 242 is removed, and the elastic force of the clamping spring 243 causes the clamping ring 241 to rotate until the clamping block 244 is pressed against the outside of the utility pole. The anti-reverse component 226 automatically inserts into the corresponding slot under its own elastic force.

[0057] Fourthly, when the climbing device 2 moves to the obstacle position, the upper rotating ring 221 is opened, and then the climbing device 2 is pushed upward by the pushing component 24 until the upper climbing component 22 passes over the obstacle and the lower climbing component 22 is located close to the lower side of the obstacle; then the lower rotating ring 221 is opened, and when the lower rotating ring 221 is opened, the unlocking arm 253 is pushed backward. The unlocking arm 253 drives the positioning pin 251 to move backward through the linkage frame 254 until it exits from the locking hole. Then, the elastic force of the climbing spring 23 pushes the lower support arm 25 upward. The lower support arm 25 drives the climbing component 22 in front of it to move upward to pass over the obstacle. Then, the lower rotating ring 221 is locked again on the outside of the utility pole; thus, the climbing device 2 passes over the obstacle and continues to climb.

[0058] Fifth step: After the climbing device 2 has climbed to the installation position, pull the adjusting component 225 away from the utility pole until the locking block is completely disengaged from the slot. Then rotate the adjusting component 225 90°. The adjusting component 225 drives the wheel frame 223 to rotate 90° synchronously. Then insert the locking block into another slot, thereby rotating the wheel frame 223 90° and locking it in position, so that the climbing device 2 can rotate around the utility pole.

[0059] Step 6: Align the right end of the fixed support arm 15 with the installation position, and install the fixed support arm 15 in the designated position using bolts. Then, rotate the rotating sleeve 16 to remove the surge arrester body 11 from the bracket 26. Next, adjust the angle of the surge arrester base 12, the first support arm 13, and the second support arm 14 by rotating and adjusting them to the required posture. Then, fix the positions of the surge arrester base 12, the first support arm 13, and the second support arm 14 to fix the surge arrester body 11 in the required position. This completes the installation of the integrated surge arrester 1.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
