Embodiment Construction
[0013] The present invention will be further described below in conjunction with drawings and embodiments.
[0014] like figure 1 , figure 2 As shown, the present invention includes a cover plate 1 and a tank body 2 made of steel plates, wherein the cover plate 1 is in the shape of a shallow tank, and the tank body 2 is in the shape of a deep tank. Each group of tank bodies 2 of the present embodiment is fixedly connected by connecting plates 3 on both sides and eight welding studs 4. The heads of the welding studs 4 are welded on the inner side of the tank body 2. A total of 8 waist-shaped holes 31 matched with welding studs 4 are arranged in a row. After the welding studs 4 pass through the waist-shaped holes 31, they are screwed together with nuts 41. Screwing together, the two sections of tank body 2 are fixedly connected together, and the waist-shaped hole 31 can be used to adjust the upper and lower positions of the connected two sections of tank body 2 . The outer s...

The invention discloses an electromagnetic pulse shield bridge, comprising cover boards and slot bodies; each slot body is fixedly connected with a plurality of fastening pieces via connecting plates at both sides; the cover board is shallow slot-shaped; a shallow slot-shaped outer lining board having a matching shape is covered outside the shallow slot-shaped cover boards; the shallow slot-shaped outer lining board is pressed at the joint of the two cover boards; systematic wedge openings are installed at the lower side of the slot rim of the cover board; the slot body is deep slot-shaped; the upper ends of both sides of the deep slot-shaped slot rim are bent into an inverted U shape inward; the edge openings of shallow slot rim of the cover board are pressed against the bending part of the deep slot rim of the slot body; a deep slot-shaped inner lining board having a shape matching the internal side of the slot body is installed inside the joint of each slot body; the ends of the deep slot rim of the lining board are abutted inside the inverted U-shaped slot at the deep slot rim of the slot body; and the inner lining board is overlapped at the joint of the two slot bodies. The electromagnetic pulse shield bridge is in completely sealed state after installation and has very good electromagnetic pulse protection effect and stable connection between each component so that the shielding effect is more stable and disassembly and assembly are also very convenient.
Description
technical field [0001] The invention relates to a fully enclosed bridge, in particular to a trough-type electromagnetic pulse shielding cable bridge, which belongs to the technical field of power transmission lines. Background technique [0002] Cable tray is an installation channel used in horizontal wiring or vertical wiring system, among which the trough cable tray is a fully enclosed cable tray, which has the advantages of shielding interference and strong protection ability, and is suitable for dustproof, rainproof, protective The laying of power cables in a demanding environment is widely used for laying control cables for computers, communications, thermocouples and other high-sensitivity systems. In the electromagnetic radiation environment, electromotive force and current may be induced in any closed metal loop, and the generation and development of nuclear explosions and atmospheric lightning will generate strong electromagnetic pulses. If there is no defense, the ...
