Abstract
Description
Technical Field
[0001] This utility model relates to the field of distribution cabinet technology, and in particular to a lightning protection distribution cabinet for a computer interlocking system. Background Technology
[0002] Distribution cabinets are mainly used to distribute power or signal lines to multiple branch circuits, enabling centralized control and distribution of electrical equipment or signal lines.
[0003] Currently used distribution cabinets mainly rely on lightning rods for lightning protection. However, the length of the lightning rods is fixed and cannot be adjusted. The lightning rods are always in a high position, which makes them prone to swaying or deformation in typhoon or strong wind areas, thereby increasing the load on the supporting structure and even causing the risk of breakage. They also occupy a lot of space during transportation and installation, increasing transportation costs and installation difficulty. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that the above-mentioned equipment is prone to breakage and increases the difficulty of transportation and installation due to the inability to adjust its length during use, and thus proposes a lightning protection distribution cabinet for a computer interlocking system.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightning protection distribution cabinet for a computer interlocking system, comprising: a lifting flashover connector;
[0006] The second lifting lightning arrester is movably inserted inside the first lifting lightning arrester. The length of the entire lightning protection device is controlled by lifting. The outer wall of the second lifting lightning arrester has two movable slots.
[0007] Two mounting bases are movably inserted inside the second lifting flash connector for installing and driving the corresponding folding structure. The top of one of the two mounting bases is fixedly connected to the top of the inner wall of the second lifting flash connector. Two fixed bases are fixedly installed on the outer walls of the two mounting bases. A rotating shaft is movably inserted into the inner walls of the four fixed bases. A folding flash connector is fixedly sleeved on the outer walls of the four rotating shafts. A shaft hole is opened on the outer walls of the four folding flash connectors. A rotating shaft is movably inserted between the inner walls of every two shaft holes.
[0008] During transportation or installation, the lightning protection device is in a retracted state, which facilitates transportation and installation in terms of time and cost. When the lightning rod is needed, the relevant device can be activated, and the mounting base at the bottom is raised by air pressure. At this time, the mounting base drives the lifting flashlight connector 2 to rise inside the lifting flashlight connector 1, thereby extending the height of the entire lightning protection device, reducing wind load, avoiding fatigue damage to the supporting structure, reducing the length of snow and ice accumulation, preventing the top ice block from tipping over due to excessive weight, and eliminating the risk of climbing for maintenance. After the lifting flashlight connector 2 has finished rising, the mounting base continues to rise, cooperating with the fixed mounting base at the top to squeeze the folded flashlight connector in the middle position. At this time, each pair of folded flashlight connectors on both sides begins to rotate the rotating shaft 1 inside the fixed base, thereby pushing the folded flashlight connector to rotate outward, so that it extends out from inside the lifting flashlight connector 2 through the movable slot, forming multi-pin collaborative protection, expanding the lightning protection coverage of the distribution cabinet and surrounding equipment, and reducing lightning blind spots.
[0009] Preferably, an insulating mounting bracket is fixedly sleeved on the outer wall of the lifting flash connector, and a distribution cabinet body is fixedly installed between the outer walls of the set of insulating mounting brackets. An insulating gas box is fixedly installed on one side of the outer wall of the distribution cabinet body, and an air pump is fixedly installed at the bottom of the inner wall of the insulating gas box. The insulating gas box is filled with insulating gas, which can be moved by the gas-driven device and can protect the internal air pump from damage caused by lightning strikes.
[0010] Preferably, the output end of the vacuum pump is fixedly connected to a gas delivery pipe, and the outer wall of the gas delivery pipe is fixedly inserted into the interior of the insulating gas box. After the vacuum pump is started, the insulating gas is delivered into the gas delivery pipe.
[0011] Preferably, the output end of the gas supply pipe is fixedly connected to an insulating interface, and the output end of the insulating interface is fixedly connected to a lifting flash connector, so that insulating gas can enter the interior of the lifting flash connector through the insulating interface.
[0012] Preferably, the bottom of the lifting flash connector is provided with a down conductor, and the bottom of the down conductor is provided with a grounding device. After the lifting flash connector is struck by lightning, the lightning is quickly conducted to the ground through the down conductor and the grounding device at the bottom, thus protecting the internal structure of the distribution cabinet.
[0013] Preferably, a limiting ring is fixedly inserted into the inner wall of the lifting flash connector one, and a sealing column is fixedly installed at the bottom of the other of the two mounting seats. The limiting ring supports the lifting flash connector two, facilitating the flow of gas to its bottom.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] In this invention, the lightning protection device remains in a retracted state during transportation and installation, significantly reducing logistics difficulties and costs. During use, insulating gas is injected into the lifting flashover unit one via an air pump. The gas pressure pushes the bottom mounting base upward, causing the lifting flashover unit two to extend vertically inside the lifting flashover unit one. When not in use, the lightning rod is at a lower height, significantly reducing fatigue damage to the supporting structure from wind loads and reducing the length of icing to prevent tipping. When the lifting flashover unit two reaches the set height, the mounting base continues to rise, working in conjunction with the top fixed base to compress the folded flashover unit, forcing it to unfold outward to form a multi-branch flashover network, expanding the lightning protection coverage of the distribution cabinet and surrounding equipment, and accurately eliminating lightning blind spots.

A rotating shaft 2 18 is movably inserted between the inner walls of every two shaft holes 17.
[0027] During transportation or installation, the lightning protection device is in a retracted state, which facilitates transportation and installation time and reduces costs. When the lightning rod is needed, the relevant device can be activated, and the mounting base 13 at the bottom is raised by air pressure. At this time, the mounting base 13 drives the lifting lightning arrester 2 10 to rise inside the lifting lightning arrester 1 6, thereby extending the height of the entire lightning protection device, reducing wind load, avoiding fatigue damage to the supporting structure, reducing the length of snow and ice accumulation, preventing the top ice block from tipping over due to excessive weight, and eliminating the risk of climbing for maintenance. After the lifting lightning arrester 2 10 has finished rising, the mounting base 13 continues to rise, cooperating with the fixed mounting base 13 at the top to squeeze the folded lightning arrester 16 in the middle position. At this time, each pair of folded lightning arresters 16 on both sides is forced to drive the rotating shaft 15 to rotate inside the fixed base 14, thereby pushing the folded lightning arrester 16 to rotate outward, so that it extends out from inside the lifting lightning arrester 2 10 through the movable slot 12, forming multi-needle collaborative protection, expanding the lightning protection coverage of the distribution cabinet and surrounding equipment, and reducing lightning blind spots.

An insulating gas box 2 is fixedly installed on one side of the outer wall of the junction box body 1. An air pump 3 is fixedly installed at the bottom of the inner wall of the insulating gas box 2. The insulating gas box 2 is filled with insulating gas, which can be moved by the gas-driven device and can protect the internal air pump 3 from damage caused by lightning strikes.
[0029] like Figure 2As shown, the output end of the vacuum pump 3 is fixedly connected to the air delivery pipe 4. The outer wall of the air delivery pipe 4 is fixedly inserted into the interior of the insulating gas box 2. After the vacuum pump 3 is started, the insulating gas is delivered into the interior of the air delivery pipe 4.
