Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of offshore substation equipment, especially to an elastic floor suitable for offshore substations. BACKGROUND

[0002] The offshore substation is a pivotal project of the offshore wind farm and is responsible for the collection, voltage increase and sending out of the electric energy of the offshore wind farm. The offshore substation is divided into an upper block and a lower structure. The upper block is usually a steel structure type of multi-deck. According to the functional requirements, the upper block is provided with electrical equipment rooms such as a main transformer room, a GIS room, a switch cabinet room, a communication and relay protection room, a battery room, and auxiliary functional rooms such as a fire pump room, a living pump room, a temporary rest room and a heating and ventilation machine room. Steel fences and outfitting materials are arranged around each room.

[0003] At present, the rooms of the offshore substation mainly achieve the purposes of heat preservation and fire prevention through outfitting materials. The main electrical equipment rooms have relatively low requirements for heat preservation due to the heat generated by the equipment. The rooms such as the fire pump room, the living pump room and the temporary rest room basically have no heat source. If the heat preservation effect of the pump room and the like is poor, the water tank and the pump set are prone to freeze in winter, which causes the paralysis of the fire-fighting system and the domestic water supply system, posing a serious safety risk to the offshore substation. If the heat preservation effect of the temporary rest room is poor, the comfort of the maintenance and repair personnel is seriously affected and the energy consumption of the heating and ventilation system is increased.

[0004] Traditionally, there are two methods for heat preservation and fire prevention of the floor of the room of the offshore substation. One is to directly arrange fireproof materials (ceramic cotton) under the steel deck and fix the fireproof materials through steel nails and steel plates. This method has the advantage of fully exerting the heat preservation of the rock wool to provide good heat preservation performance for the room. However, the steel nails and the steel plates under the steel deck are placed in the corrosive environment of the sea for a long time, which causes the rusting and falling off of the steel nails and the steel plates, and further causes the falling off of the ceramic cotton. The falling-off steel plates may cause damage to the cables and the equipment or harm to the personnel. The other is to directly arrange fireproofing material on the steel deck. The fireproofing material is mainly a cement-based fireproof material. Since the fireproofing material is arranged on the deck, the construction and maintenance are convenient. However, the heat preservation of the fireproofing material is not as good as that of the ceramic cotton. The heat preservation of the rooms such as the pump room and the temporary rest room is insufficient, which increases the energy consumption of the heating and ventilation system and affects the comfort of the maintenance personnel in winter. Therefore, we propose an elastic floor suitable for offshore substations. CONTENT OF THE UTILITY MODEL
