DETAILED DESCRIPTION

[0020] The technical solutions will be further described below in combination with specific embodiments. It should be noted that the words indicating directions such as up, down, left, right, etc. in this article are only for the positions of the shown structures in the corresponding drawings. The serial numbers of the components in this article, such as first, second, etc., are only used to distinguish the described objects and do not have any sequence or technical meaning. The connection and coupling mentioned in this application include direct and indirect connection (coupling) unless otherwise specified.

[0021] A high voltage arrester convenient for high-altitude installation, as shown in Figure 1 The high voltage arrester 1 is provided with an installation base plate 2 at the bottom, two holes are provided on the installation base plate 2, and a fixed plate 3 is installed in cooperation with the installation base plate 2. The fixed plate 3 needs to be installed in advance at the position where the high voltage arrester 1 needs to be installed. When installing the high voltage arrester 1, the installation base plate 2 can be placed flat on the fixed plate 3. Two holes are provided on the fixed plate 3. After aligning the holes on the installation base plate 2 and the fixed plate 3, the threaded rod and the nut are used to fix them, so as to achieve the purpose of fixing the high voltage arrester 1.

[0022] In the above operation process, people need to judge by eyes that the holes on the installation base plate 2 and the holes on the fixed plate 3 are aligned before using the threaded rod and the nut to fix them. It needs to be observed by eyes, which will cause visual fatigue and reduce the installation efficiency.

[0023] Therefore, the blind insertion mechanism is arranged on the mounting base plate 2, the mounting base plate 2 is quickly mounted with the fixing plate 3 in a blind insertion manner, the screw rod 4 is arranged below the hole of the mounting base plate 2, the bottom of the screw rod 4 is connected with the U-shaped plate 5, the U-shaped plate 5 is slidably connected with the mounting base plate 2, the top of the mounting base plate 2 is hoisted by the unmanned aerial vehicle and transported to the position where installation is required, the mounting base plate 2 is inserted into the fixing plate 3 from the end of the fixing plate 3, the screw rod 4 is arranged below the fixing plate 3, and the fixing plate 3 is arranged between the mounting base plate 2 and the U-shaped plate 5, then the mounting base plate 2 and the high-voltage lightning arrester 1 are manually moved along the fixing plate 3, after the screw rod 4 and the hole are aligned, the U-shaped plate 5 and the screw rod 4 are driven to rise by the elastic assembly, and the screw rod 4 is inserted into the two holes, therefore, the blind insertion can be realized only by moving the mounting base plate 2 and the high-voltage lightning arrester 1, and the installation is more rapid and convenient.

[0024] As shown in Figure 1 , the elastic assembly comprises the telescopic rod 6, the telescopic rod 6 is fixedly connected with the bottom of the mounting base plate 2 and is symmetrically arranged, the first spring 7 is arranged on the telescopic rod 6, and the first spring 7 is arranged between the mounting base plate 2 and the fixing plate 3, as shown in Figure 1 , the state of the first spring 7 is in a stretched state, the top of the screw rod 4 is located below the fixing plate 3, the mounting base plate 2 moves together with the U-shaped plate 5 and the screw rod 4, when the screw rod 4 and the hole on the mounting base plate 2 are coincided, the first spring 7 pulls the U-shaped plate 5 to rise, the U-shaped plate 5 drives the screw rod 4 to rise and is inserted into the hole of the fixing plate 3 and the hole of the mounting base plate 2, and the blind insertion can be realized.

[0025] It should be particularly noted that, in order to facilitate installation, the mounting base plate 2 is arranged in cooperation with the fixing plate 3. The mounting base plate 2 is provided with protrusions downward on the front and rear sides, the gap distance between the protrusions is consistent with the width of the fixing plate 3, and the hole spacing of the mounting base plate 2 and the fixing plate 3 is also kept consistent.

[0026] The screw rod 4 is connected with the U-shaped plate 5 through bolts, the screw rod 4 can be detached from the U-shaped plate 5, and therefore the screw rod 4 can be regularly overhauled, and the screw rod 4 is convenient to disassemble and assemble.

[0027] During the installation process, the U-shaped plate 5 needs to be manually pressed downward first, the screw rod 4 is moved downward and separated from the hole, then the mounting base plate 2 and the U-shaped plate 5 are inserted into the fixing plate 3, the fixing plate 3 is usually provided with a plurality of hole groups which are distributed at equal intervals, and the mounting base plate 2 needs to be moved along the fixing plate 3 to the required position during installation, if the screw rod 4 contacts the hole on the periphery of the fixing plate 3, the screw rod 4 will be directly inserted, but when the required installation position is located in the central direction of the fixing plate 3, the mounting base plate 2 needs to be continuously pushed, so that the screw rod 4 is not inserted into the wrong hole position, at this time, the U-shaped plate 5 needs to be continuously kept in the pressed state, so as to ensure that the screw rod 4 is not inserted into the non-target hole position, when the hole close to the required installation position is approached, the U-shaped plate 5 is released, at this time, the first spring 7 will exert the elastic force, and the installation is completed.

[0028] But as the first spring 7 for installation of the elastic force is generally larger, if each installation need people to manually keep U-shaped plate 5 down, need to overcome the first spring 7 elastic force, so the operation is very laborious, improve the difficulty of installation work, therefore, in the top of U-shaped plate 5 set against the frame 8, against the frame 8 sliding type connection in the installation of the bottom plate 2 inside, against the frame 8 will U-shaped plate 5 top against, can replace the hand to hold U-shaped plate 5, save manpower, if, need to loosen U-shaped plate 5, can manually move left against the frame 8 can loosen U-shaped plate 5.

[0029] If, need to remove the high voltage arrester 1 down for maintenance, people can screw down the nut, the next step is to press down the U-shaped plate 5, make the screw rod 4 down and separate from the hole, and the U-shaped plate 5 down, can move forward against the frame 8 against the U-shaped plate 5.

[0030] Against the frame 8 activity type set in the installation of the bottom plate 2 inside, if the activity bottom plate by external force and produce vibration, may lead to against the frame 8 left and right displacement and may misloosen U-shaped plate 5, and cause unnecessary problems, therefore, as shown in Figure 2 The second spring 9 is set between the against frame 8 and the installation of the bottom plate 2, and the elastic force of the second spring 9 improves the stability of the against frame 8, so that the against frame 8 maintains the state of resisting the U-shaped plate 5. In addition, the second spring 9 can improve the convenience of using the against frame 8. When the U-shaped plate 5 moves up, the two side plates of the U-shaped plate 5 resist the against frame 8, which can overcome the force of the second spring 9 driving the against frame 8 to move right. After the U-shaped plate 5 moves down and resets, the second spring 9 drives the against frame 8 to move and reset against the top of the U-shaped plate 5.

[0031] When installing the high voltage arrester 1 in the air, the installation project is usually large, and the number of installations is not small. Therefore, when the unmanned aerial vehicle hoists the high voltage arrester 1, multiple high voltage arresters 1 need to be hoisted at a time. Considering the convenience of hoisting multiple high voltage arresters 1, a hook column 10 is arranged on the top of the installation bottom plate 2, and a rope reel 11 is arranged at the bottom of the installation bottom plate 2. The rope reel 11 is composed of a rope, a hook, and an automatic winding assembly. The rope reel 11 is a prior art, and the present embodiment will not be explained in detail. When the rope is used, the rope can be pulled out, and when it is not used, the rope is loosened, and the rope is automatically wound into the rope reel 11.

[0032] The rope in the rope reel 11 is pulled out and the hook on the rope is hooked on the hook column 10 of another high voltage arrester 1, so that two high voltage arresters 1 can be hoisted in layers, improving the convenience of hoisting by the unmanned aerial vehicle.

[0033] In view of the balance of the high-voltage lightning arrester 1 during hoisting and installation process, the hook column 10 and the rope reel 11 are arranged at the four sides of the installation base plate 2 respectively, so that the high-voltage lightning arrester 1 is in the middle position of the rope during hoisting, and the balance of the high-voltage lightning arrester 1 is improved.

[0034] When the unmanned aerial vehicle hoists the high-voltage lightning arrester 1 to the installation position, the installation base plate 2 is placed behind the fixed plate 3, and then the rope hook and the hook column 10 need to be manually separated. Therefore, in view of the safety and convenience of installation, the hook position is unstable due to the instability of the unmanned aerial vehicle operation, so as to avoid the hands being scratched by the hook when manually unhooking. Therefore, an adaptive unlocking function is arranged, as follows:

[0035] As shown in Figures 2-3 , the hook column 10 and the installation base plate 2 are slidingly connected, the hook column 10 is provided with a slope rail 13, the slope rail 13 and the hook column 10 are slidingly connected, the installation base plate 2 is slidingly connected with a first wedge block 14 on the front and rear sides, the first wedge block 14 and the slope rail 13 are fixedly connected, and the side of the fixed plate 3 is a slope structure.

[0036] When the installation base plate 2 is inserted into the fixed plate 3, the first wedge block 14 will contact the slope of the fixed plate 3, and through the cooperation of the first wedge block 14 and the slope, the first wedge block 14 will move upward, the first wedge block 14 will move upward, the slope rail 13 will move upward, the slope rail 13 will move inward, and the hook column 10 will move inward, so that the hook column 10 will automatically decouple from the hook, without the need for manual decoupling of the hook, realizing automation, and the rope is hung on the rope reel 11.

[0037] When the hook is decoupled, the rope reel 11 is still arranged on the installation base plate 2 when the next high-voltage lightning arrester is installed, and the rope reel 11 can be recycled. If the rope reel 11 and the installation base plate 2 are fixed on the fixed plate 3, the rope reel 11 is easy to be damaged by long-term wind and rain, so the rope reel 11 is arranged to be detachable, as shown in Figure 1 , Figure 3 , the installation base plate 2 is placed on the installation base plate 2, and the rope reel 11 is arranged at the bottom of the installation rack 15. When the unmanned aerial vehicle hoists the high-voltage lightning arrester 1, the installation rack 15 can be moved into the position on both sides of the installation base plate 2, and if the high-voltage lightning arrester 1 is installed, the installation rack 15 can be moved out to take out the rope reel 11.

[0038] In order to fix the position of the mounting rack 15, the embodiment is provided with a clamping assembly, which comprises a second wedge block 16 slidably connected on one side of the mounting bottom plate 2 close to the mounting rack 15, a wedge surface is arranged on the mounting rack 15, the wedge surface of the mounting rack 15 and the second wedge block 16 are in extrusion fit, and a third spring 17 is connected between the bottom of the second wedge block 16 and the mounting bottom plate 2.

[0039] When the mounting rack 15 moves inward on both sides of the mounting bottom plate 2, the wedge surface of the mounting rack 15 and the second wedge block 16 are in contact, so that the second wedge block 16 moves downward, and the third spring 17 is compressed. When the mounting rack 15 moves into the mounting bottom plate 2, the third spring 17 drives the second wedge block 16 to move upward to limit the mounting rack 15, so as to avoid the mounting rack 15 from falling off the mounting bottom plate 2.

[0040] When the mounting rack 15 is to be taken out, the second wedge block 16 needs to be manually pressed downward to unlock the mounting rack 15, which is very troublesome. Therefore, the embodiment proposes to automatically drive the second wedge block 16 to move downward to unlock the mounting rack 15 by the driving force of the upward movement of the U-shaped plate 5, which is as follows:

[0041] As shown in Figure 4 , a rotating extrusion frame 18 is rotatably connected on one side of the mounting bottom plate 2 close to the second wedge block 16, the rotating extrusion frame 18 and the second wedge block 16 are in extrusion fit, an extrusion strip 19 is fixedly connected on one side of the U-shaped plate 5 close to the rotating extrusion frame 18, and the extrusion strip 19 and the second wedge block 16 are in extrusion fit.

[0042] When the U-shaped plate 5 moves upward to drive the extrusion strip 19 to move upward, the extrusion strip 19 moves upward and contacts the rotating extrusion frame 18, which causes the rotating extrusion frame 18 to rotate, and the rotating extrusion frame 18 drives the second wedge block 16 to move downward, and the third spring 17 is compressed. Thus, the effect of automatically driving the second wedge block 16 to move downward can be achieved. When the U-shaped plate 5 moves downward to drive the extrusion strip 19 to move downward, the extrusion strip 19 moves downward and separates from the rotating extrusion frame 18, the third spring 17 drives the second wedge block 16 to move upward, and the second wedge block 16 pushes the rotating extrusion frame 18 to reverse and reset.

[0043] After the second wedge block 16 moves downward to unlock the mounting rack 15, the mounting rack 15 needs to be manually pulled out. The embodiment is provided with a push-out plate 20 on one side of the mounting bottom plate 2 close to the mounting rack 15, the push-out plate 20 and the mounting rack 15 are in extrusion fit, and a fourth spring 21 is connected between the push-out plate 20 and the mounting bottom plate 2.

[0044] When the mounting frame 15 moves into the left and right side positions in the mounting base plate 2, the mounting frame 15 pushes the push-out plate 20 to move inward, and the fourth spring 21 is in a compressed state. Then, after the second wedge block 16 moves downward to unlock the mounting frame 15, the fourth spring 21 drives the push-out plate 20 to move outward, and the push-out plate 20 automatically pushes the mounting frame 15 out, so as to remind people that the mounting frame 15 is unlocked, and facilitate people to pull out the mounting frame 15.

[0045] Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present application.
