[0003] Although the gasoline generator and the distribution box are placed on a dry and stable insulating platform during the operation in the pit of the hydropower station, the pit of the hydropower station is relatively humid and dusty, so the original platform may become damp after a period of operation, and dust may enter the interior of the equipment, which may cause damage to the equipment. Therefore, the position of the gasoline generator and the distribution box needs to be replaced, which is more troublesome. In order to solve the above problems, a safety protection device for the pit operation of the hydropower station is urgently needed to solve the above problems. Utility Model Content

[0028] The dust-proof and dehumidifying component 3 includes a dust collecting box 35. The insulating platform 1 is slidably connected to the carrier 22 through a sliding groove provided inside the insulating platform 1. The dust collecting box 35 is fixedly installed on the bottom surface of the carrier 22. A dust conveying pipe 36 is fixedly installed on the top surface of the dust collecting box 35. An air inlet pipe 37 is fixedly installed on the top of the dust conveying pipe 36. A fan 311 is fixedly installed at one end of the air inlet pipe 37. A driving rod 310 is fixedly installed at one end of the rotating shaft of the fan 311. A filter 38 is fixedly mounted on the interior of the air inlet pipe 37, a scraper 39 is fixedly mounted on the exterior of the driving rod 310, and one side of the scraper 39 contacts the filter 38. An air conditioner 31 is fixedly mounted on the other end of the air inlet pipe 37, a ventilation duct 32 is fixedly mounted on one side of the air conditioner 31, a water pipe 33 is fixedly mounted on the bottom surface of the air conditioner 31, and a liquid storage tank 34 is fixedly mounted on the bottom surface of the carrier 22, and the liquid storage tank 34 is fixedly mounted on the bottom end of the water pipe 33.

[0029] The specific implementation method is as follows: first, the gasoline generator and the distribution box are placed in the insulating protection box 21 to prevent them from causing harm to the staff when a fault such as leakage occurs. Then, the fan 311 is started. The fan 311 draws external air into the air pipe 37 and filters the dust through the filter 38, so that the filtered air enters the air conditioner 31 and the air conditioner 31 is started. The start of the fan 311 causes the drive rod 310 to rotate, thereby causing the scraper 39 to rotate and scrape off the dust attached to the filter 38. The dust then enters the dust collection box 35 through the dust conveying pipe 36 for collection. The air entering the air conditioner 31 is condensed by the air, and the condensed water generated enters the liquid storage tank 34 through the water pipe 33. The condensed air is then input into the insulating protection box 21 through the ventilation pipe 32 to dissipate heat for the equipment therein.

[0030] The quick-release assembly 2 includes a first slider 23, the insulating platform 1 is slidably connected to the first slider 23 through a sliding groove provided therein, a carrier 22 is fixedly mounted on one side surface of the first slider 23, and a second slider 26 is fixedly mounted on one side surface of the carrier 22, the insulating platform 1 is slidably connected to the second slider 26 through a sliding groove provided therein, a positioning rod 28 is fixedly mounted inside the insulating platform 1, a rotating rod 25 is rotatably connected to the bottom surface of the insulating platform 1, a threaded rod 24 is fixedly mounted on the top of the rotating rod 25, the threaded rod 24 is rotatably connected to the inside of the insulating platform 1, the second slider 26 is slidably connected to the positioning rod 28 through a sliding hole provided therein, the first slider 23 is threadedly connected to the threaded rod 24 through a threaded hole provided therein, an insulating protection box 21 is fixedly mounted on the top surface of the carrier 22, a box body 27 is fixedly mounted on one side surface of the insulating protection box 21, an air conditioner 31 is fixedly mounted inside the box body 27, and a fan 311 is fixedly mounted on one inner wall of the box body 27.

[0031] The specific implementation method is as follows: when the insulating protection box 21 and the box body 27 need to be inspected or moved, the rotating rod 25 is rotated to rotate the threaded rod 24 to move the first slider 23 upward, thereby moving the carrier 22 upward until it is located at the unthreaded position of the threaded rod 24 and is taken out by moving the slider upward. The setting of the positioning rod 28 here not only facilitates installation and positioning, but also plays a certain stabilizing role for the entire device.

[0032] Working principle: First, put the gasoline generator and the distribution box into the insulating protection box 21 to avoid harm to the staff in the event of leakage or other faults. Then start the fan 311, which draws the external air into the air pipe 37 and filters it through the filter 38 to remove the dust. Then, the filtered air enters the air conditioner 31 and starts the air conditioner 31. The start of the fan 311 rotates the driving rod 310, which rotates the scraper 39 and scrapes off the dust attached to the filter 38. The dust then enters the dust collection box 35 through the dust conveying pipe 36 for collection, and the air entering the air conditioner 31 is removed by the air filter. The moisture is condensed, and the condensed water generated enters the liquid storage tank 34 through the water pipe 33. The condensed air is then input into the insulating protection box 21 through the ventilation duct 32 to dissipate heat for the equipment therein. When the insulating protection box 21 and the box body 27 need to be inspected or moved, the rotating rod 25 is rotated to rotate the threaded rod 24 to move the first slider 23 upward, thereby moving the carrier 22 upward until it is located at the unthreaded position of the threaded rod 24 and is removed by moving the slider upward. The setting of the positioning rod 28 here not only facilitates installation and positioning, but also plays a certain role in stabilizing the device as a whole.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
