Description

TECHNICAL FIELD

[0001] The present application relates to the field of generator technology, and in particular to a tunnel construction temporary power supply generator. BACKGROUND

[0002] A tunnel refers to a passageway dug in a mountain, underground or under the sea, used to cross geographical barriers, shorten travel distance or achieve specific transportation functions. Its core role is to break through natural terrain limitations through artificial engineering to improve transportation efficiency or resource transmission capacity. A tunnel is usually composed of an entrance, a body and auxiliary facilities. The entrance is responsible for connecting with the external environment, the body is the main passage space, and the auxiliary facilities include lighting, ventilation, drainage and other systems. Its construction needs to consider geological stability, and technologies such as concrete lining and anchor support are used to ensure structural safety. The typical characteristics are strong sealing, high space utilization and all-weather operation.

[0003] Because the tunnel is basically located in the wild, the tunnel needs to use a diesel generator for auxiliary power supply during construction to ensure that various equipment of the tunnel construction obtains normal power supply. It should be noted that when the generator is in use, air is taken in through the air inlet, and a filter element is arranged in the air inlet to filter the air. A condenser is provided to dissipate heat from the generator to ensure safe use of the generator. However, because the construction environment in the tunnel is closed, dust in the tunnel cannot be timely discharged, greatly shortening the service life of the filter element in the air inlet. In addition, during tunnel construction, impurities such as stones and mud are easily adhered to the air inlet or the condenser, thereby causing the air inlet or the condenser to not work normally, further causing the generator to have a reduced efficiency, and even causing the generator to be damaged due to poor heat dissipation.

[0070] When the generator main body 2 is in use, air is introduced through the air inlet head 4, and the air is filtered through the built-in filter element, and at the same time, heat is dissipated through the condenser 3. At this time, air enters the integrated air inlet tank 501 through the switching air inlet tank 502, and then enters the air inlet auxiliary pipe 9, and then enters the air inlet head 4 through the follow-up hose 8. At the same time, the air inlet auxiliary filter plate 503 filters the dust, stones or mud and other impurities in the external air, so as to avoid excessive wear and tear of the filter element in the air inlet head 4 and shorten the service life.

[0071] Further, with the continuous use of the air inlet auxiliary filter plate 503, the impurities on the air inlet auxiliary filter plate 503 accumulate and sink under force, thereby driving the air inlet auxiliary filter plate 503 to move downwards, and the load-bearing rod 510 moves in the load-bearing sleeve 511, and the load-bearing spring 512 is contracted under force. When the air inlet auxiliary filter plate 503 moves downwards, one of the switching racks 507 is driven to move, so that the switching rack 507 drives the switching gear 506 to rotate, and the switching gear 506 drives the other switching rack 507 to move, thereby driving the pipeline blocking plate 504 to move. When the weight of the air inlet auxiliary filter plate 503 reaches a specified weight, the pipeline blocking plate 504 is separated from the air inlet auxiliary pipe 9. At this time, the push-pull sliding plate 514 is driven to move under the pushing force of the plurality of pushing springs 515, so that the push-pull sliding plate 514 drives the air inlet auxiliary pipe 9 to move, and the air inlet auxiliary pipe 9 slides at the bottom side of the integrated air inlet tank 501 and moves to the position of the next pipeline blocking plate 504, and is blocked by the pipeline blocking plate 504, so that the air inlet auxiliary pipe 9 is aligned with the other switching air inlet tank 502. In addition, the movement of the air inlet auxiliary pipe 9 drives the bottom side sliding box 509 to move, so that the bottom side sliding box 509 moves on the positioning plate 516, so as to maintain the sealing property of the bottom side sliding box 509, and the movement of the bottom side sliding box 509 drives the top side sealing cover 508 to move, so that the next switching air inlet tank 502 is automatically exposed for use, realizing the automatic switching of the switching air inlet tank 502 and maintaining the continuous air intake of the air inlet head 4.

[0072] It should be noted that when the intake auxiliary pipe 9 moves, the wedge-shaped push block 610 is driven to move, so that the wedge-shaped push block 610 drives the arc-shaped top block 609 to move, the arc-shaped top block 609 drives the lifting linkage frame 607 to move upwards, the lifting linkage frame 607 moves vertically in the lifting sliding groove 611, and the lifting spring 612 is stressed, the lifting linkage frame 607 moves to drive the linkage shaft 608 to move, the linkage shaft 608 moves to drive the driven rotary lever 606 to rotate, so that the driven rotary lever 606 drives the unfolding rotary shaft 604 to rotate, the unfolding rotary shaft 604 rotates in the unfolding rotary groove 603, and the unfolding torsional spring 605 is stressed, so that the unfolding rotary shaft 604 drives the external blocking plate 601 to rotate, the external blocking plate 601 rotates on the mounting frame 602 through the two unfolding rotary shafts 604, and then the external blocking plate 601 is vibrated by the plurality of arc-shaped vibration blocks 613 when the external blocking plate 601 rotates, so that the impurities on the external blocking plate 601 are shaken off; in addition, when the intake auxiliary pipe 9 continuously moves, the wedge-shaped push block 610 is separated from the arc-shaped top block 609, and then the external blocking plate 601 is reset, so that the automatic cleaning of the external blocking plate 601 is realized, and the normal use of the condenser 3 is ensured.

[0073] Further, when the lifting linkage frame 607 moves upwards, the double-sided rack frame 705 is driven to move upwards, so that the double-sided rack frame 705 drives the two drive gears 706 to rotate, the drive gears 706 rotate to drive the connecting shaft 707 to rotate, the connecting shaft 707 rotates to drive the drive rotary lever 703 to rotate, the drive rotary lever 703 drives the drive sliding plate 702 to move through the drive rotary shaft 704, so that the drive sliding plate 702 drives the sliding scraping frame 701 to move, the sliding scraping frame 701 scrapes off the impurities on the top side of the generator housing 1, ensures the cleanliness of the generator housing 1, and then ensures the normal heat dissipation of the generator housing 1.

[0074] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
