Description

Technical Field

[0001] The present invention relates to the technical field of fire protection, and in particular to a modular cable penetration sealing fire protection device and a use method thereof. Background Art

[0002] With the development of industrial technology, modern circuit system technology is becoming more and more perfect. When laying cables on the roadside or around factory buildings, the main part of the cable can be buried underground, but the connection nodes of the cable need to be connected to the distribution box on the ground. For those areas where workers frequently move around, workers are prone to touch the cables, which can easily cause the cables to break away from the distribution box;

[0003] Secondly, the wiring of the cables is prone to electric sparks and even fire. Although the distribution box module can wrap the cable nodes, the overly tight wrapping also leads to poor heat dissipation of the distribution box module. Summary of the invention

[0004] The purpose of the present invention is to provide a modular cable penetration sealing fireproof device and a method of using the same. When the device is in use, when electric sparks appear at the connection ends of the cables, the flying sparks will be blocked by the fireproof cover, and the heat generated by the circuit system can be diffused through the airflow in the heat dissipation groove and the gap between the seals. When the cable is connected to a fault and sprays flames, the asbestos fireproof cover has the effect of blocking the flames, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a modular cable penetration sealed fireproof device and a method of using the same, comprising a module base, a cover plate cavity is provided on both sides of the left and right sides of the module base, a cover plate is fixedly installed inside the cover plate cavity by bolts, four mutually docking semicircular channels are provided on the cover plate cavity and the opposite side walls of the cover plate, the upper and lower semicircular channels form a threading groove, a cable is inserted inside the threading groove, a locking component is provided at the inner port of the threading groove, and a buffer mechanism is provided inside the threading groove; an assembly cavity is provided inside the module base, a quick wiring component is provided inside the assembly cavity, and a fireproof cover is provided at the top of the assembly cavity; the fireproof cover includes a fireproof cover, a heat dissipation groove is provided at the top of the fireproof cover, a seal is provided on the inner side of the heat dissipation groove, the seal is fixedly connected to the side wall of the fireproof cover through a support sheet, the cross-section of the heat dissipation groove and the seal is T-shaped, and the heat dissipation groove and the seal are suspended.

When a cable connection fault occurs and flames are ejected, the asbestos fireproof cover has the effect of blocking the flames.

[0017] Secondly, the cable to be processed passes through the wire threading trough, and the cable and the piston plate are hot-fused together. After the cable passes through the interior of the wiring short tube, a hexagonal bolt is inserted into the bolt rod, rotated and locked in position. The end of the cable is then bent upward 90 degrees and passed through the wiring through-hole on the side wall of the assembly block. After the wiring bridge is clamped at the ends of the two cables, the two cables can be connected. When the cable is collided, the cable will compress the strong spring to buffer the collision, and the wiring part inside the cable will not be pulled apart under the buffering condition.
