[0001] The utility model belongs to the technical field of high-voltage power transmission and distribution lines, in particular to an electric shock protection device for a high-voltage power transmission and distribution line tower. Background Art
[0002] High-voltage transmission and distribution line towers are supports used to support transmission lines in overhead transmission lines. Their function is to ensure the stability and reliability of transmission lines. High-voltage transmission towers enable power lines to be transmitted at high altitudes, reducing the electromagnetic resistance and friction on the ground, thereby improving the efficiency of power transmission. Towers can be divided into reinforced concrete poles, steel pipe poles, angle steel towers and steel pipe towers according to their manufacturing materials. At the same time, according to the stress conditions in the transmission and distribution lines, they can be divided into suspension towers and tension towers. High-voltage transmission and distribution line towers are an indispensable part of the power system. Their design, manufacture, installation and maintenance must strictly comply with relevant standards and specifications to ensure the safe, stable and efficient operation of the power system.
[0003] During daily use, high-voltage transmission and distribution line towers are relatively safe. However, due to some unexpected circumstances or improper human construction operations nearby, the line may be disconnected. At this time, if the broken wire is grounded, it will continue to discharge to the ground. When animals move nearby or people are unaware, electric shock incidents may occur. It may also come into contact with construction machinery, causing electric shock to operators. Therefore, an anti-electric shock device for high-voltage transmission and distribution line towers is proposed. Utility Model Content

[0006] The firing assembly includes a main body shell, a pair of sliding push blocks are slidably connected inside the main body shell, and a first counterweight block is movably connected inside the main body shell.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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] like Figures 1 to 4 As shown, the utility model provides an electric shock protection device for a high-voltage transmission and distribution line tower, comprising a tower body 1, a pair of insulating ceramic frames 2 fixedly connected to both sides of the tower body 1, a firing assembly 3 fixedly connected to the bottom between the pair of insulating ceramic frames 2, a transmission line 4 movably connected inside the firing assembly 3, a retraction assembly 5 fixedly connected to both sides of the tower body 1, a second counterweight 6 placed inside the retraction assembly 5;
[0022] The firing assembly 3 includes a main shell 301 , a pair of sliding push blocks 302 are slidably connected to the interior of the main shell 301 , and a first counterweight block 304 is movably connected to the interior of the main shell 301 .
[0023] The above scheme is adopted: when the transmission line 4 is disconnected due to human or other reasons, the transmission line 4 will fall downward, and the sliding push blocks 302 on both sides will be driven by the transmission line 4 to move, so that the sliding push blocks 302 push the support baffle 303 to move, causing the first counterweight block 304 to lose support and fall from the inside of the main shell 301, so that it pulls the clamping block 503 to move through the action of gravity, and releases the clamping block 503 with the load-bearing bracket 501, so that the second counterweight block 6 can fall out from the inside of the load-bearing bracket 501, and under the action of gravity, the transmission line 4 is pulled downward by the traction rope, so that the wire end of the disconnected transmission line 4 is pulled up and suspended in the air, and cannot be touched.
[0024] like Figure 2 and Figure 3As shown, the firing assembly 3 also includes a sliding push block 302 fixedly connected to the transmission line 4, and the sliding push block 302 is located between a pair of support baffles 303. A limit rod is provided inside the main body shell 301, located on both sides of a pair of first counterweights 304, and a spring is provided at one end of the support baffles 303 away from each other, and the spring is wrapped around the outside of the first counterweight 304. The first counterweight 304 is located inside the support baffle 303, and the transmission line 4 is within the distance between the pair of tower bodies 1, and a baffle is provided every third.
[0025] The above scheme is adopted: by setting a firing assembly 3, the sliding push block 302 pushes the support baffle 303 to move, and the limiting rod is used to limit the first counterweight block 304, and the first counterweight block 304 is pushed down from the support baffle 303, so that the first counterweight block 304 loses support, and the first counterweight block 304 falls from the bottom of the main body shell 301, and the firing traction belt 504 is pulled under the action of gravity. By setting a spring at one end of the support baffle 303 away from each other, the support baffle 303 is limited by the spring, which can prevent the transmission line 4 from pushing the support baffle 303 to move due to wind or a few birds landing on the transmission line 4. By setting a baffle on the transmission line 4, it can be prevented that the transmission line 4 is completely pulled to the vicinity of the tower body 1 and then falls off the tower body 1, thereby discharging near the tower body 1, or falling onto the tower body 1, thereby discharging the tower body 1.
[0026] like Figure 2 、 Figure 3 and Figure 4 As shown, the pulling assembly 5 includes a load-bearing bracket 501, and the bottom of the load-bearing bracket 501 is rotatably connected to the bottom support plate 502, and the bottom support plate 502 is elastically connected to the clamping block 503. The end of the clamping block 503 close to each other is fixedly connected to the firing traction belt 504, the clamping block 503 is clamped to the load-bearing bracket 501, and the firing traction belt 504 is fixedly connected to the bottom of the first counterweight block 304. The second counterweight block 6 is located on the upper side of the clamping block 503, and a traction rope is provided on the side of the second counterweight block 6. One end of the traction rope is sleeved on the outside of the transmission line 4 and is located between the main shell 301 and the insulating ceramic frame 2.
[0027] The above scheme is adopted: by setting up a pulling component 5, the firing traction belt 504 pulls the clamping block 503 to move, and the clamping block 503 and the load-bearing bracket 501 are released, so that the second counterweight block 6 can fall from the inside of the load-bearing bracket 501, and the firing traction belt 504 is fixedly connected to the bottom of the first counterweight block 304, so that the first counterweight block 304 can be pulled to move by the firing traction belt 504 under the action of gravity, and a traction rope is set on the side of the second counterweight block 6, and one end of the traction rope is sleeved on the outside of the transmission line 4, so that the second counterweight block 6 can pull the transmission line 4 when falling, so that the disconnection can be pulled to be suspended in the air.
[0028] The working principle and usage process of the present invention are as follows: during use, when the power transmission line 4 is disconnected due to human or other reasons, the power transmission line 4 will fall downward and drive the sliding push blocks 302 on both sides to move, so that the sliding push blocks 302 push the support baffle 303 to move, causing the first counterweight block 304 to lose support and fall from the inside of the main shell 301, and then the clamping block 503 is pulled to move by triggering the traction belt 504, releasing the clamping block 503 with the load-bearing bracket 501, so that the clamping block 503 flips downward, so that the second counterweight block 6 can fall out from the inside of the load-bearing bracket 501, and by pulling the power transmission line 4 downward, the disconnected part of the power transmission line 4 is pulled up and suspended in the air to prevent people or animals from coming into contact with it and getting an electric shock.
[0029] It is worth noting that when the disconnection point of the power transmission line is too close to the firing assembly 3 at one end, the weight is insufficient and the sliding push block 302 will not be pulled to move, and the block can be directly suspended in the air.
[0030] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
[0031] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
