Description

Technical Field

[0001] The utility model relates to a temporary hole for a cable to pass through a wall. Technical Background

[0002] Affected by the humid environment by the sea, the equipment in the power plant is severely corroded. When workers repair the power supply, they need to open the door of the switchgear. The cable enters through the door. Over time, the moisture by the sea will enter the switchgear, resulting in condensation on the electrical equipment in the switchgear and generating many water droplets, which is likely to cause a short circuit in the circuit and lead to a trip. To sum up, a temporary hole for a cable to pass through a wall is needed to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problem of temporarily using a repair power supply without allowing moisture to enter the switchgear, and provides a temporary hole for a cable to pass through a wall.

[0004] To solve the above deficiencies, the utility model adopts the following technical solutions:

[0005] A temporary hole for a cable to pass through a wall, which comprises a mounting iron pipe passing through the wall. The mounting iron pipe is fixed through through-hole A. A rolling mechanism is fixedly installed inside the iron pipe. There is through-hole B in the wall above the iron pipe, and through-hole C in the wall below the iron pipe. The inner side of the wall is fixedly connected to baffle A at through-hole B through fixing bolts and fixing nuts. The outer side of the wall is fixedly connected to baffle B at through-hole B through fixing bolts and fixing nuts. Through-hole C is movably connected to baffle A on the inner side of the wall and baffle B on the outer side of the wall through a through-bolt.

[0006] Four groups of fixing buckles are fixed on the inner circumferential wall of the sleeve. Each group of fixing buckles has two. A roller is movably installed on each of the fixing buckles.

[0007] For the temporary hole for a cable to pass through a wall, rubber pads are adhesively bonded to the surfaces of baffle A and baffle B with glue. Beneficial Effects

[0008] 1. For the utility model, baffle A and baffle B are movably connected to the through-nut to realize the fixation of the baffles on both sides inside and outside the wall. The rubber pads adhesively bonded to the baffle surfaces can reduce the entry of moisture or rainwater, avoiding the generation of water droplets on the electrical equipment and causing short circuits.

[0009] 2. When the utility model is in use, the cable enters through-hole A from outside the wall. Through the rolling of the rollers inside the sleeve, the cable passes through the wall more easily, saving the working time of the maintenance personnel.

[0010] 2. The structure of the utility model is simple and easy to install, which improves the convenience of cable entry into the room for maintenance personnel during power source maintenance, enhances work efficiency, and eliminates potential safety hazards caused by unauthorized cable entry into the room. Description of the Drawings

Detailed Implementation Manner

[0016] Referring to Figure 1 - Figure 2 , a temporary hole for a cable to pass through a wall, which comprises an installation iron pipe 2 passing through the wall 1, and the installation iron pipe is fixed through the through hole A8. A rolling mechanism is fixedly installed inside the iron pipe, and the rolling mechanism includes a sleeve 15. Four groups of fixing buckles 16 are fixed on the inner circumferential wall of the sleeve, with two fixing buckles in each group. A roller 17 is movably installed on each fixing buckle. There is a through hole B9 on the wall above the iron pipe, and a through hole C10 on the wall below the iron pipe. The baffle A3 and the baffle B4 are fixedly connected on both sides inside and outside the wall through a fixing bolt 5 and a fixing nut 6 at the through hole B, and the baffle A and the baffle B are movably connected through a through bolt 7 at the through hole C.

[0017] Referring to Figure 3 , for the temporary hole for a cable to pass through a wall, there are two through holes D11 on the baffle A, and a rubber pad A13 is adhesively bonded to the surface of the baffle A.

[0018] Referring to Figure 4 , for the temporary hole for a cable to pass through a wall, there are two through holes E12 on the baffle B, and a rubber pad B14 is adhesively bonded to the surface of the baffle B.

[0019] Working Principle:

[0020] When maintenance personnel are performing maintenance on the power supply, the through nuts of this device are removed, the baffle A and the baffle B are slid upward, the cables that need to enter the room are passed through the iron pipes in the wall and into the room. The cables can smoothly enter the room through the rolling of the rollers. After the detection is completed, the cables are withdrawn, the baffle A and the baffle B are lowered and closed, and the baffle A and the baffle B are fixed by passing the through bolts through the through hole C under the wall and the through holes of the baffle A and the baffle B, which can prevent the seaside moisture from entering the power distribution room and avoid the occurrence of circuit short - circuit caused by water droplets on electrical equipment.
