Description

Technical field:

[0001] The utility model belongs to the field of wind turbines, and in particular relates to a fireproof plugging device for a cable through hole of a tower platform of a wind turbine. Background technology:

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of a wind wheel, a generator, a tail, a tower, a speed limit safety mechanism, and cables.

[0003] During the cable laying process of a wind turbine, the cables will successively pass through a multi-layer working platform (referred to as the tower platform) built inside the tower. A through hole for the cable to pass through is opened at the outer edge of the tower platform. After passing through the through hole, the cable is fixed on the inner wall of the tower. Although the through hole facilitates the smooth passage of the cable, there will still be a large gap left after the cable passes through. When a fire occurs in the tower, the gap created by the through hole forms a chimney effect, causing the fire to spread rapidly upward along the gap, which poses a major hidden danger to the fire safety of the wind turbine. Utility model content:

[0004] The utility model aims to provide a fireproof plugging device for cable through holes of a wind turbine tower platform, and overcomes the deficiencies of the above-mentioned prior art, and effectively solves the existing problem of fire safety caused by the gap of the cable through hole.

[0005] The content of the utility model: A fireproof plugging device for cable passage holes of a wind turbine tower platform, comprising a tower platform, a cable passage opening being opened on the tower platform, a fireproof plugging plate being matched with the cable passage opening, a through hole being opened on the fireproof plugging plate, the through hole being used for the cable to pass through, an enclosure being matched with the cable passage opening, the enclosure being vertically fixedly mounted on the top wall of the tower platform, a plurality of brackets being mounted on the fireproof plugging plate, and the top ends of the brackets being hung on the enclosure.

[0006] Furthermore, a blocking strip is installed on the fireproof blocking plate, and the blocking strip is used to reduce the opening of the through hole.

[0007] Furthermore, the fireproof blocking plate, the blocking plate strip and the hanging bracket are fixedly connected by bolts.

[0008] Furthermore, the through hole is U-shaped.

[0009] The beneficial effects of the utility model are as follows: the gap between the cable passage and the cable can be reduced by the fireproof blocking plate, thereby eliminating the chimney effect formed by the gap, thereby preventing the fire from spreading rapidly upward along the gap when a fire occurs, and reducing the potential fire safety hazards.

[0015] Specifically, the gap between the cable passage 2 and the cable 5 can be reduced by the fireproof blocking plate 3 .

[0016] During actual use, the fireproof plug 3 is placed in the cable passage 2, and the cable 5 is passed through the through hole 4. At this time, the fireproof plug 3 can block the gap between the cable passage 2 and the cable 5; the plugging strip 6 further reduces the opening of the through hole 4, so that the gap between the through hole 4 and the cable 5 is minimized, and the plugging strip 6 can be installed on the top wall or bottom wall of the fireproof plug 3; the enclosure 7 can not only prevent the operators from stepping on the fireproof plug 3, but also prevent the operators from kicking the cable 5 and causing damage to it; the fireproof plug 3 can be quickly hung on the top edge of the enclosure 7 through the bracket 8; the bolt 9 can facilitate the rapid installation or disassembly between the fireproof plug 3 and the plugging strip 6 and the bracket 8; the U-shaped through hole 4 facilitates the rapid passage of the cable 5.
