Description

Technical Field

[0001] The invention relates to the technical field of hydropower station protection, in particular to an equipment moisture-proof isolation device for a pumped storage power station. Background Art

[0002] Electrical cabinets and switch cabinets are commonly used equipment in hydropower stations. Due to the special environment of hydropower stations, they are often humid, and ordinary cabinets cannot effectively prevent internal equipment from getting damp, thus affecting their use.

[0003] At present, the moisture-proof measures commonly used in the cabinets of hydropower stations are heating, placing dehumidifiers, or installing insulation layers to remove moisture. Although these measures can alleviate the impact of environmental humidity on the equipment in the cabinets to a certain extent.

[0004] However, in actual application, it is found that these cabinets usually have average moisture-proof performance and cannot cope with relatively harsh and humid environments; they do not have a warning function, and their moisture-proof performance will decrease after long-term use. Once a situation that cannot be coped with suddenly occurs, the staff cannot respond in time, which can easily cause the equipment to be damaged by moisture; moreover, these existing cabinets are usually fixed in use, which is not convenient for staff to move the cabinets when replacing or adjusting the equipment. Summary of the invention

[0005] The object of the present invention is to provide a moisture-proof isolation device for equipment in a pumped storage power station. The present invention has the advantages of better moisture-proof performance and easy transportation and use.

[0006] The technical solution of the present invention is as follows: a moisture-proof isolation device for equipment in a pumped-storage power station comprises an isolation cabinet, a supporting base plate arranged at the bottom of the isolation cabinet, air intake structures correspondingly distributed on the left and right sides of the isolation cabinet, an exhaust unit arranged in the middle of the lower part of the supporting base plate and connected to the isolation cabinet, and a plurality of adjustment feet correspondingly distributed below the supporting base plate; the adjustment feet are correspondingly distributed on the outer part below the supporting base plate, and a roller foot is correspondingly provided on the inner side of each adjustment foot; the height of the adjustment foot is adjustable, and the bottom height of the roller foot is within the height adjustment range of the bottom of the adjustment foot; and a cabinet door that can be opened and closed is provided in front of the isolation cabinet.

[0007] In the aforementioned moisture-proof isolation device for pumped-storage power stations, the adjustable foot comprises a liftable foot unit and a lifting unit arranged outside the foot unit for adjusting the lifting of the foot unit; the lifting unit is linked to the foot unit through a bevel gear set.

[0008] In the aforementioned moisture-proof isolation device for pumped-storage power stations, the foot unit includes a foot seat, a threaded rod lifting sleeved under the foot seat, and a foot block rotatably connected to the bottom of the threaded rod.

[0009] In the aforementioned moisture-proof isolation device for equipment in a pumped-storage power station, the lifting unit includes a vertically arranged rotating handle and a horizontally arranged rotating shaft connected to the rotating handle; the bevel gear set includes a main bevel gear sleeved on the end of the rotating shaft and a secondary bevel gear horizontally arranged in a base seat and meshing with the main bevel gear; the secondary bevel gear drives the threaded rod to rotate and lift.

[0010] In the aforementioned moisture-proof isolation device for equipment of a pumped-storage power station, the roller foot comprises a roller seat rotatably connected to a supporting base plate and a roller rotatably disposed in the roller seat.

[0011] In the aforementioned moisture-proof isolation device for equipment in a pumped-storage power station, a filter chamber is provided at the bottom of the air intake structure, and an observation chamber connected to the isolation cabinet is provided at the top; air ducts for air intake are correspondingly opened in the air intake structure, the filter chamber and the observation chamber; the air duct of the air intake structure is filled with replaceable moisture-proof filler; the air duct of the filter chamber is filled with replaceable filter filler; the observation chamber is transparent, and a replaceable color-developing filler is provided in the air duct of the observation chamber.

[0012] In the aforementioned moisture-proof isolation device for equipment in a pumped-storage power station, an openable and closable protective cover is provided on the outer side of the air intake structure, and the protective cover corresponds to the airway.

[0013] In the aforementioned moisture-proof isolation device for equipment in a pumped storage power station, the filter chamber is in the shape of an inverted trapezoid with a larger top and a smaller bottom, and an air inlet for air intake is provided on the outer side of the bottom of the filter chamber.

[0014] In the aforementioned moisture-proof isolation device for pumped-storage power stations, a waterproof plate is provided on the top of the isolation cabinet, a water receiving pan is provided above the waterproof plate, and a pair of drainage pipes connected to the water receiving pan are provided on the rear side of the waterproof plate.

[0015] In the aforementioned moisture-proof isolation device for equipment in a pumped-storage power station, the exhaust unit includes an exhaust chamber, an exhaust fan arranged in the exhaust chamber, exhaust holes distributed on the outer wall of the exhaust chamber, and filter material filled in the exhaust chamber.

[0016] Compared with the prior art, the present application arranges air intake structures on both sides of the isolation cabinet and arranges an exhaust unit at the bottom of the isolation cabinet. The air intake structure and the exhaust unit are combined to form an air circulation in the isolation cabinet. The exhaust unit discharges the gas in the isolation cabinet from the bottom, and the air intake structure filters and dehumidifies the gas entering the isolation cabinet, effectively ensuring that the isolation cabinet is not affected by moisture.

[0017] By arranging a supporting base plate at the bottom of the isolation cabinet, and arranging corresponding adjusting feet and roller feet at the bottom of the supporting base plate, the bottom height of the adjusting feet can be telescopically adjusted according to actual needs, and the bottom height of the roller feet is within the adjustment range of the adjusting feet. When the bottom of the adjusting feet is higher than the roller feet, the roller feet are in contact with the ground, thereby facilitating the movement and transportation of the isolation cabinet by the roller feet; when the bottom of the adjusting feet is lower than the roller feet, the bottom of the adjusting feet abuts against the ground, thereby supporting and fixing the isolation cabinet, ensuring that the isolation cabinet can be used stably.

[0018] Therefore, the present invention has the advantages of better moisture-proof performance and convenient transportation and use. BRIEF DESCRIPTION OF THE DRAWINGS
