Figure 2-Figure 8 , a power supply equipment for tunnel construction provided by an embodiment of the present invention also includes an emergency flip protection device 4, which is installed on the installation frame 3, and the emergency flip protection device 4 is used to flip the two power supply distribution cabinets 1 into the temporary protection box 2; specifically, the emergency flip protection device 4 includes an L-shaped flip plate 401, and the L-shaped flip plate 401 is rotatably installed in the temporary protection box 2. The two power supply distribution cabinets 1 are both located on the top side of the L-shaped flip plate 401, and a flip shaft 402 is rotatably installed in the temporary protection box 2. The L-shaped flip plate 401 is installed on the flip shaft 402, and flip push rods 403 are installed at both ends of the flip shaft 402. A load-bearing frame 404 is movably installed on the installation frame 3, and two L-shaped lower push frames 405 are installed on one side of the load-bearing frame 404. The L-shaped lower push frame 405 moves downward to push the flip push rod 403 to rotate, and a connecting socket 414 is installed on the two power supply distribution cabinets 1.

[0024] It should be noted that, in the embodiment of the present invention, when a car or an engineering vehicle loses control and travels in the direction of the power supply distribution cabinet 1, it first presses on the load-bearing frame 404, and the load-bearing frame 404 moves downward, driving the two L-shaped lower push frames 405 to move downward, so that the L-shaped lower push frames 405 squeeze the flip push rod 403 to rotate, and the flip push rod 403 drives the L-shaped flip plate 401 to rotate through the flip shaft 402. The rotation of the L-shaped flip plate 401 drives the two power supply distribution cabinets 1 to rotate, and then the power supply distribution cabinet 1 is rotated into the temporary protection box 2; in addition, when the L-shaped flip plate 401 rotates, it drives the protection airbag 412 to rotate, so that the airbag cable 413 is pulled out, and at this time the protection airbag 412 explodes, so that the car or engineering vehicle can hit the protection airbag 412, which can further avoid the power supply distribution cabinet 1 and effectively protect the car or engineering vehicle at the same time; It should be further explained that when rockfall occurs in the tunnel, if the scale of the rockfall is large, it may hit the top guard plate 410, and the top guard plate 410 drives the two load-bearing brackets 409 to move, and the load-bearing brackets 409 drive the load-bearing frame 404 to move, thereby also achieving the purpose of flipping the power supply distribution cabinet 1 into the temporary protection box 2.

[0025] More specifically, the embodiment of the present invention further includes a water-immersion lifting protection device 5, which is mounted on the installation frame 3 and is used to lift and protect the power distribution cabinet 1. The water-immersion lifting protection device 5 includes a lifting floating plate 501, which is slidably mounted on the installation frame 3. The L-shaped flip plate 401 has two lifting chutes 508, and the two lifting chutes 508 are each slidably mounted with a lifting slide 509. The two connecting sockets 414 are respectively slidably mounted in the two lifting slides 509. It should be noted that in the embodiment of the present invention, when water accumulation occurs in the tunnel, the lifting floating plate 501 floats due to the rising water level, thereby causing the connecting slide 411 to move upward. The connecting slide 411 drives the power distribution cabinet 1 and the lifting slide 509 to move upward through the connecting socket 414, thereby achieving the purpose of driving the power distribution cabinet 1 upward when the water level rises, thereby preventing the power distribution cabinet 1 from being soaked by water.

[0026] More specifically, the embodiment of the present invention further includes an automatic linkage cleaning device 7, which is mounted on the mounting frame 3 and is used to clean the power distribution cabinet 1. The automatic linkage cleaning device 7 includes two linkage cleaning frames 701, which are respectively located on the sides of the two power distribution cabinets 1 that are separated from each other. The linkage cleaning frames 701 are used to clean the filter plate 6.

[0035] Please continue to refer to the instructions attached Figure 2 and Figures 9-11 More specifically, in the embodiment of the present invention, a driving plate 710 is installed between the two downward-pressing drive frames 703, and auxiliary rotating plates 711 are rotatably installed on both sides of the driving plate 710. It should be noted that in the embodiment of the present invention, when an automobile or construction vehicle passes in front of the power distribution cabinet 1, it first contacts and squeezes the auxiliary rotating plates 711, allowing the automobile or construction vehicle to smoothly move onto the driving plate 710.

[0036] In summary, the working principle of a power supply device for tunnel construction provided by an embodiment of the present invention is as follows: When the power supply distribution cabinet 1 is installed in the tunnel for use, if a car or an engineering vehicle loses control and drives towards the power supply distribution cabinet 1, it first presses on the load-bearing frame 404, causing the load-bearing frame 404 to move on the installation frame 3 through the four load-bearing pressure rods 406, and causing the four load-bearing springs 407 to move downward under the force, and the downward movement of the load-bearing frame 404 drives the two L-shaped lower push frames 405 to move downward, thereby causing the L-shaped lower push frames 405 to squeeze the flip push rod 403 to rotate, and the flip push rod 403 drives the L-shaped flip plate 401 to rotate through the flip shaft 402, and the rotation of the L-shaped flip plate 401 drives the two power supply distribution cabinets 1 to rotate, and the rotation of the power supply distribution cabinet 1 drives the two connecting sockets 414 to disengage from the two connecting slots 415, thereby causing the power supply distribution cabinet 1 to rotate into the temporary protection box 2 and be blocked by the closed limit strip 420, so that the power supply distribution cabinet 1 is suspended in the temporary protection box 2 to prevent the power supply distribution cabinet 1 from being hit; In addition, it should be noted that when the L-shaped flip plate 401 rotates, it drives the protective airbag 412 to rotate, thereby pulling out the airbag cable 413. At this time, the protective airbag 412 explodes, allowing the car or engineering vehicle to hit the protective airbag 412, which can further prevent the power supply distribution cabinet 1 from falling and effectively protect the car or engineering vehicle. In addition, when rockfall occurs in the tunnel, if the scale of the rockfall is large, it can hit the top guard plate 410, thereby causing the top guard plate 410 to drive the two load-bearing brackets 409 to move, and then the load-bearing brackets 409 drive the load-bearing frame 404 to move, thereby also achieving the purpose of flipping the power supply distribution cabinet 1 into the temporary protection box 2; Furthermore, when water accumulates in the tunnel, the lifting floating plate 501 floats due to the rising water level, thereby driving the two synchronous driving plates 506 to move, and the movement of the two synchronous driving plates 506 drives the synchronous push shaft 507 to move, so that the synchronous push shaft 507 synchronously squeezes the two wedge-shaped driving frames 502 to move, thereby causing the two wedge-shaped driving frames 502 to disengage from the two limiting slots 505. At this time, under the rebound force of the two lifting springs 504, the lifting spring 504 drives the lifting slide 503 to move, and the movement of the lifting slide 503 drives the connecting slide 411 to move, and the connecting slide 411 drives the power distribution cabinet 1 and the lifting slide 509 to move upward through the connecting socket 414, and the lifting slide 509 moves vertically upward in the lifting slide 508, thereby achieving the purpose of driving the power distribution cabinet 1 to move upward when the water level rises, thereby avoiding the problem of the power distribution cabinet 1 being soaked by water; Furthermore, when a car or an engineering vehicle passes in front of the power distribution cabinet 1, it can be moved to the driving plate 710 through the auxiliary rotating plate 711, and press the driving plate 710 downward. The downward movement of the driving plate 710 drives the two downward pressure driving frames 703 to move. The two downward pressure driving frames 703 move vertically in the two downward pressure grooves 708 and cause the push-up spring 709 to contract. At the same time, the two downward pressure driving frames 703 move through the two linkage rotating rods 702 to drive the two linkage cleaning frames 701 to move. When the filter plate 6 is fully cleaned, the filter 6 can be automatically cleaned by the filter element 701. When the filter plate 6 is fully cleaned, the filter plate ...
