Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a device for blocking cable inlet and outlet ports of a power distribution room. Background Art

[0002] The work of protecting high-voltage cabinets and low-voltage cabinets in distribution rooms from small animals has always faced great challenges, especially in the autumn and winter seasons, when small animals enter the distribution room, causing accidents such as line tripping and equipment short circuits in the distribution room. This can easily lead to short circuits and burnouts of distribution equipment, causing power outages, and directly affecting people's normal electricity use. At present, fireproof mud, rubber rings, etc. are commonly used to seal the inlet and outlet of cables in high- and low-voltage cabinets in distribution rooms. Due to the physical properties of fireproof mud and rubber rings, they are easy to fall off and deform in a humid environment, making the sealing tightness unable to meet actual needs. Although the existing sealing device has improved the sealing tightness, the sheath used to protect the cable is easy to slip after being damp, resulting in the sealing device not being ideal in moisture-proof effect.

[0003] After searching, Chinese patent CN209217643U discloses a plugging device for cable inlet and outlet of a power distribution room, including a detachable fastening device, a moisture-proof gasket and a detachable connecting sleeve, wherein the moisture-proof gasket is arranged between the detachable connecting sleeve and the detachable fastening device, and the detachable connecting sleeve is provided with a connector for connecting the detachable fastening device, and the connector is provided with an anti-slip structure for locking the moisture-proof gasket. The utility model has a simple structure, can be quickly disassembled and assembled, and is time-saving and labor-saving to install.

[0004] However, the installation end of the cable inlet and outlet sealing device of the utility model in the distribution room lacks a sealing structure. When the cable passes through the detachable fastening device, although it is sealed by the moisture-proof gasket, with the passage of time, the elasticity of the anti-slip structure decreases and the pressure of the moisture-proof gasket gradually decreases, causing moisture to easily enter from the unsealed end, easily causing a short circuit accident. Therefore, it cannot meet the use requirements. Therefore, a cable inlet and outlet sealing device for a distribution room is proposed to solve the above problems. Utility Model Content
