[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution including: an insulating umbrella body 1 and a clamping mechanism 2 detachably mounted on the umbrella body; the clamping mechanism 2 includes a first clamping arm 22 and a second clamping arm 23, and a clamping space for the utility pole 4 is formed between the first clamping arm 22 and the second clamping arm 23. The first clamping arm 22 can move away from or close to the utility pole 4, and the second clamping arm 23 can rotate to allow the utility pole 4 to enter the clamping space.

[0026] During installation, the insulating umbrella and clamping mechanism are carried to the designated position. First, the second clamping arm 23 is rotated to create a clamping space for the utility pole 4. Then, the first clamping arm 22 is pushed closer to the second clamping arm 23 so that the clamping mechanism is clamped onto the utility pole 4. Finally, the umbrella is installed below the clamping mechanism. In other words, the movable first clamping arm 22 in this invention makes the clamping space adjustable, thus making it suitable for utility poles 4 of different sizes, while greatly ensuring the safety of the workers.

[0027] In a further embodiment, the insulating umbrella body 1 includes two separate half-umbrella surfaces, each half-umbrella surface being composed of three umbrella blades, which are connected by hinges.

[0028] The system is designed with two separate half-canopies, which can be fitted onto the outside of the utility pole 4 and then secured by an upper clamping mechanism to ensure the safety of personnel working on live lines. When workers climb the utility pole 4, the half-canopies can be folded into individual canopy pieces for easy carrying.

[0029] In a further embodiment, the clamping mechanism 2 includes a locking member for adjusting the distance between the two clamping arms; it also includes a self-locking member 26 disposed on the locking member for locking the clamping arms after the distance is adjusted.

[0030] That is, the first clamping arm 22 is moved by the locking component so that the clamping mechanism clamps the utility pole 4, and the position of the first clamping arm 22 is locked by the self-locking component, thus ensuring the fixing effect of the clamping mechanism.

[0031] In a further embodiment, a limiting component is also included. The limiting component includes a fixed base 24, on which two sets of light rods 25 are arranged side by side. The two sets of light rods 25 cooperate with the first clamping arm 22 and the second clamping arm 23 to form a clamping space. The two ends of the first clamping arm 22 are slidably mounted on the light rods 25. One end of the second clamping arm 23 is rotatably connected to the light rod 25. The bottom of the other end of the second clamping arm 23 is provided with a notch. A knob plug 27 is provided at the notch to disengage or lock the second clamping arm 23 from the other light rod 25.

[0032] When attaching the clamping mechanism 2 to the outside of the power line, the knob plug 27 can be adjusted first to open the notch at the bottom of the second clamping arm 23, one end of the second clamping arm 23 can be taken out from a smooth rod 25, and the second clamping arm 23 can be rotated around the other end of the smooth rod 25 to attach the clamping mechanism to the outside of the power pole 4.

[0033] In a further embodiment, both ends of the second clamping arm notch are provided with threads that are adapted to the knob plug 27, wherein the knob plug 27 is an L-shaped handle-type self-locking spring positioning pin.

[0034] In a further embodiment, the first clamping arm 22 and the second clamping arm 23 are each provided with rollers 28 on their relatively close sides; thus, it is convenient to adjust the position of the clamping mechanism relative to the utility pole 4.

[0035] In a further embodiment, four rotating locking members 5 are rotatably installed at the bottom of the fixing base 24, and rotating grooves 11 are provided on the two half umbrella surfaces; when the rotating locking member 5 is rotated to the first position, the rotating locking member 5 can be inserted into the rotating groove 11, and when the rotating locking member 5 is rotated to the second position, the rotating locking member 5 can lock the fixing base 24 to the half umbrella surface;

[0036] When installing the umbrella canopy, first rotate the locking component to the first position, and install the two halves of the umbrella canopy onto the clamping mechanism through the rotating groove. Then rotate the locking component to the second position to fix the half umbrella canopy onto the utility pole 4 through the clamping mechanism 2 and assemble them into a complete insulating umbrella canopy to ensure the safety of workers under high-voltage power lines.

[0037] In a further embodiment, the locking member includes a positioning plate 21 disposed on the fixed base 24, the positioning plate 21 being located at the end of the first clamping arm 22 away from the second clamping arm 23, and a self-locking member 26 being provided at the end of the positioning plate 21 away from the first clamping arm 22; it also includes a pull rod 29, one end of which is mounted on the first clamping arm 22, and the other end of which passes through the self-locking member 26, so that the self-locking member 26 limits the position of the pull rod 29.

[0038] When adjusting the clamp spacing, the first clamping arm 22 is moved by the pull rod first. After the first clamping arm 22 is adjusted to a suitable position, the position of the pull rod 29 can be limited by the self-locking part 26 to prevent it from moving.

[0039] In a further embodiment, a compression spring is also sleeved on the pull rod 29. The two ends of the compression spring abut against the positioning plate 21 and the first clamping arm 22 respectively, and the elastic element is in a compressed state when the first clamping arm 22 clamps the utility pole 4.

[0040] When clamping the utility pole 4, first open the second clamping arm 23, and then pull the lever 29 to move the first clamping arm 22 backward to put the utility pole 4 into the clamping space, so as to provide stable clamping of the utility pole 4 by squeezing the compression spring.

[0041] In a further embodiment, the end of the pull rod 29 away from the first clamping arm 22 is provided with a handle 262, and the self-locking component 26 includes a cam self-locking handle 261 and a clamping seat; the clamping seat is provided with a pull rod channel, and the cam self-locking handle 261 is provided above the clamping seat to adjust the clamping degree of the pull rod; the self-locking component can also be other structures in the prior art that can lock the pull rod 29.

[0042] By setting the cam self-locking handle 261, the position of the pull rod 29 can be quickly locked, which facilitates the rapid erection of the insulating umbrella and creates a safe space for subsequent live work on the utility pole 4; at the same time, it can provide a large locking force on the pull rod, which ensures the locking effect on the utility pole 4 and further ensures the stability of the insulating umbrella.

[0043] In a further embodiment, each of the two halves of the umbrella is provided with an insulating splicing strip 3 at one end close to each other, and a notch 31 is provided at the splicing point of the two insulating splicing strips 3; since the utility pole 4 is usually fixed with a cable, the cable can pass through the insulating umbrella through the notch 31; at the same time, it avoids affecting the insulation effect and causing safety hazards by directly setting a notch on the insulating umbrella.

[0044] In a further embodiment, the insulating splicing strip 3 is fixed to the two halves of the umbrella surface by Velcro; thus facilitating the disassembly and replacement of the insulating splicing strip 3.

[0045] Working principle and usage process of this utility model:

[0046] The staff first rotates the second clamping arm 23 to open it, and then puts the utility pole 4 into the clamping space. During this process, the compression spring pushes the first clamping arm to automatically clamp the utility pole 4. The first clamping arm is locked by the cam self-locking handle 261, and the two folded half-umbrellas are opened. Then, the two half-umbrellas are fixed to the bottom of the clamping mechanism by rotating the locking piece 5, thus completing the installation of the insulating protective umbrella. For disassembly, the umbrella can be removed first, and then the clamping mechanism can be taken off.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
