Technical Field

The invention relates to the technical field of wind driven generators, in particular to a fireproof sealing system for a tower cylinder of a wind driven generator and a construction method of the fireproof sealing system.

Background

Currently, wind power generation has become an important direction for the development of renewable energy sources worldwide. In recent years, the wind power industry in China is rapidly developing continuously, and the installed capacity is gradually enlarged. After a large number of novel wind turbine generator products are put into large-scale production and operation in a short time, the problems of quality and operational reliability are outstanding, and safety accidents occur frequently. In the operation safety accident of the wind turbine generator, the fire accident occupies a considerable proportion, the generator is always burnt out, and the economic loss is huge. Along with the increase of unit operating duration, unit spare part wears out ageing gradually, and the fault rate promotes constantly, and the conflagration risk is also bigger. The fire rapidly spreads in a narrow space, even a gap of one point becomes a fire spreading passage, and if the fire is not sealed and isolated, a large fire will be generated.

Wind generating sets are mostly distributed in remote areas, once a fire disaster occurs, fire extinguishing personnel cannot reach the wind generating sets quickly, and even if the fire extinguishing personnel arrive, the wind generating sets cannot work when facing a huge wind generating set, and only power supplies can be cut off. The above causes a loss that cannot be recovered in time when a fire occurs.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a fireproof plugging system for a tower cylinder of a wind driven generator and a construction method thereof, which can realize passive fire prevention, seal and isolate a fired area and an unfired area, ensure the continuity and integrity of a civil structure and prevent flame, smoke and toxic gas from spreading and spreading.

In one aspect of the present invention, a fireproof sealing system for a tower of a wind turbine is provided, which includes:

the fireproof plate covers a through hole used for penetrating a cable harness on the tower barrel, the fireproof plate is fixedly connected with a protective edge of the through hole, a wire fixing hole matched with the cross section of the cable harness is further formed in the fireproof plate, non-solidified fireproof mud is filled in a gap between the cable harness and the wire fixing hole, an overlap joint part is formed between the fireproof plate and the protective edge of the through hole of the tower barrel, and the solidified fireproof mud is filled in the overlap joint part.

The beneficial effects of the above technical scheme are: the PLASTIC LAMINATED that sets up can block the flame and pass through the hole and stretch, the non-setting type fire prevention mud that sets up meets fire and takes place the inflation, and the material is fine and close unrecoverable after the inflation, and form the carbomorphism protective layer, this carbomorphism protective layer can be high temperature resistant for a long time and not produce the crack, finally form the fire prevention district and separate, thereby reach flame and do not stretch, smog does not pierce through, delay heat transfer's effect by a wide margin, make this system can prevent fires passively, reduce the loss, when the conflagration breaing out, the core part can be in the state of sealed protection, because the PLASTIC LAMINATED can bear the high pressure, be that the outside is put out a fire through the high-pressure squirt promptly, also can not have water.

And the angle steel is fixed on one side of the through hole and used for supporting the fireproof plate. Some edges of some of the through holes are not provided with guard plates, so that when the fireproof plate is fixed, the fireproof plate on the side without the guard plates cannot be fixed, and the arranged angle steel can provide support for the fireproof plate in the position without the guard plates.

Further, the cable bundle is bundled by adopting a fire retardant belt. The fire retardant belt can prevent fires, and tie up the bundling and can make the cable regular more, reduced the cost of maintaining.

Further, fireproof paint is coated on the cable bundles positioned at the two ends of the wire fixing hole, and the coating length of each end is 450 mm and 550 mm. The fire-retardant coating can prevent the insulating material on the outer layer of the cable bundle from burning and can prolong the transmission time of high temperature in the cable bundle.

Further, the non-solidified type fire-proof mud is MP + non-solidified type fire-proof mud.

Further, the solidified fire-proof mud is CP25WB + solidified fire-proof mud.

In another aspect of the invention, a construction method for a fireproof sealing system of a tower of a wind driven generator is provided, which comprises the following steps:

s1, preprocessing, wherein the preprocessing comprises the steps of cleaning sundries penetrating through the holes, classifying cables according to functions and trends, and bundling the classified cables into bundles by using fire retardant belts;

s2, mounting a fireproof plate, cutting the size of the fireproof plate according to the size of the through hole, forming a wire fixing hole according to the cross section shape of a cable bundle to be penetrated, fixing the cut fireproof plate on a protective plate of the through hole through bolts, supporting and fixing the edge without the protective plate by using angle steel, and filling solidified fireproof mud in a gap between the fireproof plate and the protective plate;

and S3, threading, namely penetrating the treated cable bundle into a wire fixing hole of the fireproof plate, filling a gap between the cable bundle and the wire fixing hole with non-solidified fireproof mud, and coating fireproof paint on the cable bundle at two ends of the wire fixing hole.

Further, the thickness of the fireproof coating is 0.5-1.5 mm.
