[0002] Wind power generation, as a green and clean energy, has been widely used. However, compared with traditional energy, wind power generation has the characteristics of volatility and intermittency, which makes the power output of wind farms unstable. In order to efficiently and reliably connect the electricity generated by wind power generation to the power grid, substation equipment plays a vital role in wind farms.

[0003] The patent with publication number CN209497169U relates to a box-type substation for wind turbines, including a transformer room, a low-voltage room and a high-voltage room, wherein the high-voltage room includes a high-voltage incoming line terminal, a high-voltage outgoing line terminal and a self-test device, wherein the high-voltage incoming line terminal is connected to a plurality of wind power generation equipment, and the high-voltage outgoing line terminal of the high-voltage room is connected to the transformer room, wherein the transformer room includes a transformer, a temperature sensor and a heat dissipation device, wherein one end of the transformer is connected to the low-voltage room, wherein the self-test device includes a self-test incoming line terminal, a battery and a self-test system, wherein the self-test incoming line terminal is connected to a single wind power generation equipment, and ... low-voltage room and a high A battery is connected to the incoming line end of the inspection, and the battery is connected to a self-inspection system. The device adopts an independent unidirectional wind power generation equipment to power the self-inspection device. A fault occurring at any position will not affect the normal operation of the self-inspection device, and the fault problem can be detected by the self-inspection device. The detection is more comprehensive, the structure is reasonable, and the practicability is strong. However, during the long-term use of the device, the vents of the substation will be covered with dust because no one has cleaned them for a long time, which makes it difficult for the heat inside the substation to dissipate. Therefore, a box-type substation for wind power generation is proposed to solve the above-mentioned problems. Summary of the invention

The bidirectional screw rod 43 rotates to drive the sliding plate 47 to move backward, and the movement of the sliding plate 47 drives the straight rod 48 to move.

The movable plate 1 511 is rotatably connected to the inner wall of the fire extinguishing box 510. When smoke and fire are generated inside the substation, the smoke detector 7 will detect the generated smoke and transmit the signal to the motor 42, thereby extending the reversal time of the motor 42. At this time, the sliding plate 47 moves to drive the inclined block 1 51 to move. After the reversal time of the motor 42 is extended, the inclined block 1 51 will contact the inclined bar 53, so that the inclined block 1 51 generates a squeezing force on the inclined bar 53, forcing the inclined bar 53 moves upward, the inclined bar 53 moves upward and contacts with the limit block 59, and generates an extrusion force on the limit block 59 to move the limit block 59, and the movement of the limit block 59 will release the limit on the card block 58.

[0016] Working principle: when the vent of the substation is full of dust, the motor 42 starts, the motor 42 starts to drive the bidirectional screw rod 43 to rotate forward, the bidirectional screw rod 43 rotates to drive the sliding plate 47 to move backward, the sliding plate 47 moves to drive the straight rod 48 to move, the straight rod 48 moves to produce an extrusion force on the hinged rod 49 to make the hinged rod 49 move and rotate, the hinged rod 49 moves to drive the sliding rod 410 to move, the sliding rod 410 moves along the slide groove of the inner wall of the U-shaped frame 45, the sliding rod 410 moves to drive the scraper 411 to move, so that the dust, mud and other impurities attached to the surface of the air permeable plate 46 can be dropped, thereby improving the air permeability in the substation. The heat dissipation effect of the whole part is achieved. At the same time, the movement of the sliding rod 410 drives the fixed rod 412 to move, the movement of the fixed rod 412 drives the brush roller 413 to move, and the movement of the brush roller 413 drives the transmission wheel 414 to move. When the transmission wheel 414 moves, it will generate friction with the surface of the air-permeable plate 46 to cause self-rotation. The rotation of the transmission wheel 414 drives the brush roller 413 to rotate, thereby further cleaning the dust on the surface of the air-permeable plate 46 and avoiding the blockage of the air holes on the inner wall of the air-permeable plate 46, so that the ventilation effect inside the substation is further enhanced. Similarly, the reversal of the motor 42 will repeat the above effect again, but the forward rotation time of the motor 42 will be the same as the reversal time.

[0017] When smoke and fire are generated inside the substation, the smoke detector 7 will detect the generated smoke and transmit a signal to the motor 42, thereby extending the reversal time of the motor 42. At this time, the sliding plate 47 moves to drive the inclined block 1 51 to move. After the reversal time of the motor 42 is extended, the inclined block 1 51 will contact the inclined bar 53, so that the inclined block 1 51 generates a squeezing force on the inclined bar 53, forcing the inclined bar 53 to move upward. The upward movement of the inclined bar 53 will contact the limit block 59 and generate a squeezing force on the limit block 59 to move the limit block 59. The movement of the limit block 59 will release the limit on the card block 58. After the card block 58 releases the limit, it will bounce back. The spring 1 56 will bounce back and reset, driving the sliding rod 2 55 to move upward. The upward movement of the sliding rod 2 55 drives the inclined block 2 57 to move upward.

At the same time, the rotation of the movable plate 1 511 will produce an extruding force on the push plate 515, thereby pushing the push plate 515 to move, so that the push plate 515 can push out all the dry powder remaining in the fire extinguishing box 510 to avoid the generation of residual dry powder.

At the same time, the rotation of the rotating plate 65 drives the card plate 66 to rotate. The rotation of the card plate 66 will contact the inner wall of the box shell 2 to make the card plate 66 rotate, so that when no fire occurs, the vibration caused by the rotation of the wind turbine can be avoided, causing the rotating plate 65 to rotate by itself and drive the partition plate 2 64 to fall, thereby preventing the temperature inside the substation from dissipating.
