Abstract

The invention relates to a ventilation structure and a cable protection device. The ventilation structure includes: a main body with a cavity, a first ventilation port and a second ventilation port located at both ends of the main body and communicated with the cavity; a waterproof component, including a waterproof member arranged in the cavity, and the waterproof member has opposite sides to each other. the first end and the second end and the ventilation holes provided at both ends; the inner diameter of the cavity gradually decreases from the end provided with the first ventilation port to the end provided with the second ventilation port; the waterproof member is close to the second ventilation port It is arranged that the first end of the waterproof member is closer to the second ventilation opening than the second end, and the radial dimension of the ventilation hole gradually decreases from the first end to the second end. The cable protection device includes: a casing, a window, and the ventilation structure as described above. Compared with the prior art, the cable protection device can not only meet the requirements of the cable maintenance working environment for rainproof and dustproof, but also realize ventilation and ventilation, and improve the working environment of the cable maintenance staff by setting the ventilation structure. .

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a ventilation structure and a cable protection device for cable wiring. Background technique [0002] In electric power engineering, when carrying out high-voltage cable wiring work in cable wells, the requirements for the site environment are relatively high, and the site needs to have certain functions such as rain and dust protection. A canvas shed was substituted and sealed all around. However, the airtightness of this kind of shed is too strong, and the air is not circulated. Especially in summer, when people make cable joints in the shed, it is sultry and uncomfortable, and it is easy to suffer from heat stroke, which seriously affects the work efficiency. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a ventilation structure and a cable protection device for cable wiring work in order to solve the ventilation problem, which can take ...
