Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a ventilation device for an electrical room of a thermal power plant. Background Art

[0002] Thermal power generation is the main form of power generation in my country. With the continuous improvement of thermal power generation technology, the power load capacity of power plants is getting higher and higher. Thermal power plants are gradually developing towards large capacity, high parameters and high performance. The capacity of electrical rooms is constantly increasing, and the heat dissipation is increasing, forming many high-heat electrical rooms. Since a large number of transformers and other equipment are installed inside the plant, a large amount of heat will be generated when the transformers and other equipment are operating normally. If the internal heat cannot be dissipated in time, it will not only affect the normal operation of the thermal power plant, but also cause certain safety hazards.

[0003] In the prior art, common heat dissipation and ventilation devices in the electrical room of a thermal power plant mostly use exhaust ducts to extract the heat inside the electrical room. However, this method has poor air circulation, resulting in unsatisfactory heat dissipation effects. In addition, in order to prevent dust accumulation from affecting electrical equipment, most electrical rooms are closed spaces, which further leads to slow heat dissipation and easily creates safety hazards.

[0004] Therefore, a ventilation device for an electrical room of a thermal power plant is proposed to solve the above problems. Utility Model Content

[0011] As a preferred implementation, the bottom of the installation frame is installed through the top of the installation platform.

[0012] As a preferred implementation, the surface of the top of the support base is fixedly connected to the bottom of the electrical room, and one end of the support base is connected through an air supply duct.

[0013] As a preferred implementation, the surfaces of the hollow steel frame and the mounting frame are coated with an insulating coating, and the insulating coating is made of phenolic resin paint.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. The utility model installs a hollow steel frame on the bottom side of the interior of the electrical room, and the bottom is suspended by a mounting platform. The mounting platform should be pre-buried in the ground so that the bottom of the electrical room is flush with the external ground. Different numbers of mounting racks are installed above the hollow steel frame according to usage requirements. Electrical equipment is installed on the mounting racks. The hair dryer and the exhaust fan are started by an external controller. After the hair dryer is started, air is sent downward through the mounting pipe to blow the heat emitted by the electrical equipment on the top of the mounting rack to the bottom of the electrical room and enter the support base through the hollow steel frame. After the exhaust fan is started, the hot air in the support base is extracted and sent to the outside through the air supply pipe, so that air flow heat is formed inside the electrical room to enhance the heat dissipation effect.

[0016] 2. In the utility model, two installation frames are installed on the top of the installation platform. Two layers of filter plates are installed inside the installation frames through the installation slots. When the hair dryer is started, the external air is drawn through the installation frames and sent into 1. The air passing through the installation frames will first be filtered through the filter plates before entering the electrical room. By setting the filtering device, the air flow is ensured to improve the heat dissipation effect, while preventing the dust in the air from affecting the electrical equipment.
