Technical Field

[0001] This invention relates to the field of power supply equipment technology, and in particular to a power supply equipment for tunnel construction. Background Technology

[0002] During tunnel construction, temporary power supply is required for lighting. This necessitates the installation of power distribution cabinets within the tunnel. However, due to the large number of passing cars and construction vehicles, accidents causing these cabinets to lose control could result in them crashing into the cabinets. Additionally, tunnel collapses could damage the cabinets, or flooding could submerge them, leading to a power outage and forcing construction to halt, severely impacting the project's progress. Summary of the Invention

[0003] The purpose of this invention is to provide a power supply device for tunnel construction to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0012] Both sides of the connector socket are provided with synchronous slots, and both sides of the inner wall of the connector slot are provided with shrinkage grooves. Synchronous rods are movably installed in both shrinkage grooves. The two synchronous rods are respectively locked in the two synchronous slots. A connecting spring is installed on the inner wall of the shrinkage groove, and the connecting spring is installed on the synchronous rod.

[0013] Furthermore, in a preferred embodiment of the present invention, load-bearing pressure bars are slidably installed at the four corners of the mounting frame, and the load-bearing pressure bars are installed on the load-bearing frame;

[0014] Load-bearing springs are installed at the four corners of the mounting frame. The load-bearing springs are mounted on the load-bearing frame, and protective covers are installed on the mounting frame and the load-bearing frame.

[0015] Furthermore, in a preferred embodiment of the present invention, a sealing limit strip is installed on the inner wall of the temporary protective box, the sealing limit strip being used to restrict the position of the L-shaped flip plate.

[0016] Furthermore, in a preferred embodiment of the present invention, lifting carriages are slidably installed in both of the two load-bearing supports, both of the two lifting carriages are installed on the top guard plate, and the connecting slide is installed on the two lifting carriages;

[0017] A lifting spring is installed on the bottom side of the lifting carriage, and the lifting spring is installed on the inner wall of the load-bearing bracket.

[0018] Furthermore, in a preferred embodiment of the present invention, wedge-shaped drive frames are movably installed on both of the two load-bearing supports, and limiting slots are provided on both of the two lifting slides, with the two wedge-shaped drive frames respectively inserted into the two limiting slots;

[0019] Two synchronous drive plates are installed on the top side of the lifting floating plate, and a synchronous push shaft is installed between the two synchronous drive plates.

[0020] Furthermore, in a preferred embodiment of the present invention, the automatic linkage cleaning device further includes two downward driving frames, which are slidably mounted on both sides of the load-bearing frame, and a linkage rotating rod is rotatably mounted on the top side of the downward driving frame, and the linkage cleaning frame is mounted on the linkage rotating rod;

[0021] The load-bearing frame has downward pressure grooves on both sides, and the two downward pressure drive frames are slidably installed in the two downward pressure grooves respectively. An upward push spring is installed on the inner wall of the downward pressure groove and is installed on the downward pressure drive frame.

[0022] Furthermore, in a preferred embodiment of the present invention, the pressing drive frame is provided with a mounting slot, a mounting shaft is rotatably mounted in the mounting slot, the linkage rod is mounted on the mounting shaft, and a limit stop is installed on the top side of the pressing drive frame, the limit stop being used to limit the position of the linkage rod;

[0023] A support torsion spring is installed on the inner wall of the mounting slot, and the support torsion spring is mounted on the mounting shaft.

[0024] Furthermore, in a preferred embodiment of the present invention, a traveling plate is installed between the two downward pressing drive frames, and auxiliary rotating plates are rotatably installed on both sides of the traveling plate.

[0025] The beneficial effects of the power supply equipment for tunnel construction proposed in this invention are:

[0026] In this invention, by setting up an emergency rollover protection device, when a car or construction vehicle loses control and travels towards the power distribution cabinet and presses against the load-bearing frame, the load-bearing frame moves downward, causing the two L-shaped push brackets to move downward. This causes the L-shaped push brackets to press the rollover push rod to rotate. The rollover push rod drives the L-shaped rollover plate to rotate via the rollover shaft. The rotation of the L-shaped rollover plate causes the two power distribution cabinets to rotate. The rotation of the power distribution cabinets causes the two connecting sockets to disengage from the two connecting slots, thereby causing the power distribution cabinets to rotate into the temporary protection box for protection. When the L-shaped rollover plate rotates, it causes the protective airbag to rotate, thereby causing the airbag cable to be pulled out. At this time, the protective airbag will deploy, allowing the car or construction vehicle to collide with the protective airbag, which can further prevent the power distribution cabinet from being damaged and can also effectively protect the car or construction vehicle. In addition, when a rockfall occurs in the tunnel, if the rockfall is large and hits the top guard plate, the top guard plate will cause the two load-bearing supports to move, which in turn causes the load-bearing supports to move the load-bearing frame, thus achieving the purpose of rolling the power distribution cabinet into the temporary protection box.

[0027] Furthermore, in this invention, by setting up a water-soaking lifting protection device, when water accumulates in the tunnel, the lifting floating plate floats upward due to the rising water level, thereby driving two synchronous driving plates to move. The movement of the two synchronous driving plates drives the synchronous push shaft to move, causing the synchronous push shaft to synchronously squeeze the two wedge-shaped driving frames to move. This causes the two wedge-shaped driving frames to disengage from the two limiting slots. At this time, under the rebound force of the two lifting springs, the lifting springs drive the lifting slide to move. The movement of the lifting slide drives the connecting slide to move. The connecting slide drives the power distribution cabinet and the lifting slide to move upward through the connecting socket. The lifting slide moves vertically upward within the lifting slide groove, thereby achieving the purpose of driving the power distribution cabinet to move upward when the water level rises, avoiding the problem of the power distribution cabinet being soaked in water.

[0028] Furthermore, in this invention, by setting up an automatic linkage cleaning device, when a car or engineering vehicle passes in front of the power distribution cabinet, it can move onto the traveling plate via an auxiliary turntable and press the traveling plate down. The downward movement of the traveling plate drives two downward pressing frames to move, which in turn drives two linkage cleaning frames to move. When the car or engineering vehicle leaves the auxiliary turntable, under the rebound force of two upward pushing springs, it drives the two downward pressing frames to move up, realizing the vertical up and down movement of the linkage cleaning frames. Therefore, the filter plate is thoroughly cleaned, achieving the purpose of automatic cleaning of the filter plate and ensuring the heat dissipation effect of the power distribution cabinet.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] Please refer to the attached instruction manual. Figures 1-11The present invention provides a power supply device for tunnel construction, which includes two power distribution cabinets 1 and a temporary protection box 2. The temporary protection box 2 is installed underground and has an installation frame 3. Both power distribution cabinets 1 are located inside the temporary protection box 2, and filter plates 6 are installed on both sides of the power distribution cabinets 1. A connecting sleeve 8 connects the two power distribution cabinets 1.

[0045] Further, please refer to the appendix to the instruction manual. Figures 2-8 The present invention provides a power supply equipment for tunnel construction, which further includes an emergency flip protection device 4. The emergency flip protection device 4 is installed on the mounting frame 3 and is used to flip two power distribution cabinets 1 into a temporary protection box 2. Specifically, the emergency flip protection device 4 includes an L-shaped flip plate 401, which is rotatably installed in the temporary protection box 2. Both power distribution cabinets 1 are located on the top side of the L-shaped flip plate 401. 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. Both ends of the flip shaft 402 are equipped with flip push rods 403. A load-bearing frame 404 is movably installed on the mounting frame 3. Two L-shaped push brackets 405 are installed on one side of the load-bearing frame 404. The L-shaped push brackets 405 move down to push the flip push rods 403 to rotate. Both power distribution cabinets 1 are equipped with connection sockets 414.

[0046] It should be noted that, in this embodiment of the invention, when a car or construction vehicle loses control and travels toward the power distribution cabinet 1, it first presses on the load-bearing frame 404. The load-bearing frame 404 moves down, causing the two L-shaped pushers 405 to move down, which in turn causes the L-shaped pushers 405 to press the flipping push rod 403 to rotate. The flipping push rod 403 drives the L-shaped flipping plate 401 to rotate through the flipping shaft 402. The rotation of the L-shaped flipping plate 401 drives the two power distribution cabinets 1 to rotate, thereby causing the power distribution cabinets 1 to rotate into the temporary protection box 2. In addition, when the L-shaped flipping plate 401 rotates, it drives the protective airbag 412 to rotate, thereby causing the airbag cable 413 to be pulled out. At this time, the protective airbag 412 explodes, allowing the car or construction vehicle to collide with the protective airbag 412, which can further avoid the power distribution cabinet 1 and effectively protect the car or construction vehicle.

[0047] It should be further explained that when a rockfall occurs in the tunnel, if the rockfall is large, it can hit the top guard plate 410. The top guard plate 410 will move the two load-bearing brackets 409, and the load-bearing brackets 409 will move the load-bearing frame 404, thereby achieving the same purpose of flipping the power distribution cabinet 1 into the temporary protection box 2.

[0048] More specifically, in this embodiment of the invention, a water-soaking lifting protection device 5 is also included. The water-soaking lifting protection device 5 is installed on the mounting frame 3 and is used to lift and protect the power distribution cabinet 1. The water-soaking lifting protection device 5 includes a lifting float 501, which is slidably installed on the mounting frame 3. Two rising grooves 508 are provided on the L-shaped flip plate 401, and rising carriages 509 are slidably installed in each of the two rising grooves 508. Two connecting sockets 414 are slidably installed in the two rising carriages 509 respectively. It should be noted that in this embodiment of the invention, when water accumulates in the tunnel, the lifting float 501 floats upward due to the rising water level, causing the connecting slide 411 to move upward. The connecting slide 411, through the connecting sockets 414, drives the power distribution cabinet 1 and the rising carriages 509 upward, thereby achieving the purpose of moving the power distribution cabinet 1 upward when the water level rises, preventing the power distribution cabinet 1 from being submerged in water.

[0049] More specifically, in this embodiment of the invention, an automatic linkage cleaning device 7 is also included. The automatic linkage cleaning device 7 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 located on opposite sides of the two power distribution cabinets 1. The linkage cleaning frames 701 are used to clean the filter plate 6. It should be noted that in this embodiment of the invention, when a car or engineering vehicle passes in front of the power distribution cabinet 1, the vertical up-and-down movement of the linkage cleaning frames 701 thoroughly cleans the filter plate 6, achieving the purpose of automatic cleaning of the filter plate 6.

[0050] Please continue to refer to the instruction manual appendix. Figures 2-8 Furthermore, the emergency overturning protection device 4 provided in this embodiment of the invention for power supply equipment for tunnel construction also includes two load-bearing supports 409, both load-bearing supports 409 are installed on the load-bearing frame 404, and a top guard plate 410 is movably installed on the top side of the two load-bearing supports 409.

[0051] In addition, a connecting slide 411 is movably installed between the two load-bearing brackets 409, a protective airbag 412 is installed on one side of the L-shaped flip plate 401, an airbag cable 413 is connected to the protective airbag 412, the airbag cable 413 is connected to the connecting slide 411, and both connecting sockets 414 are inserted into the connecting slide 411. It should be noted that, in this embodiment of the invention, when a car or construction vehicle loses control and travels towards the power distribution cabinet 1, it presses against the load-bearing frame 404. The load-bearing frame 404 moves downward, causing the two L-shaped push brackets 405 to move downward, which in turn causes the L-shaped push brackets 405 to press the flip push rod 403 to rotate. The flip push rod 403 drives the L-shaped flip plate 401 to rotate via the flip shaft 402. The rotation of the L-shaped flip plate 401 drives the two power distribution cabinets 1 to rotate. The rotation of the power distribution cabinets 1 causes the two connecting sockets 414 to disengage from the two connecting slots 415, thereby causing the power distribution cabinets 1 to rotate into the temporary protection box 2. In addition, when the L-shaped flip plate 401 rotates, it drives the protective airbag 412 to rotate, thereby causing the airbag cable 413 to be pulled out. At this time, the protective airbag 412 explodes, allowing the car or construction vehicle to collide with the protective airbag 412, which can both avoid the power distribution cabinet 1 and effectively protect the car or construction vehicle.

[0052] More specifically, in this embodiment of the invention, the connecting slide 411 has two connecting slots 415, and two connecting sockets 414 are respectively inserted into the two connecting slots 415; both sides of the connecting sockets 414 are provided with synchronous slots 417, and both sides of the inner walls of the connecting slots 415 are provided with shrinkage grooves 416, and synchronous levers 418 are movably installed in both shrinkage grooves 416. The two synchronous levers 418 are respectively locked in the two synchronous slots 417, and a connecting spring 419 is installed on the inner wall of the shrinkage groove 416. The connecting spring 419 is installed on the synchronous lever 418. It should be noted that, in this embodiment of the invention, when the L-shaped flip plate 401 is reset, the connecting socket 414 is inserted into the connecting slot 415, and the two synchronous locking rods 418 are squeezed back into the two shrinking grooves 416, and the two connecting springs 419 are subjected to force. When the connecting socket 414 continues to move, under the rebound force of the two connecting springs 419, the two synchronous locking rods 418 are locked in the two synchronous locking slots 417, thereby achieving the purpose of quickly connecting the power distribution cabinet 1 and the connecting slide 411.

[0053] More specifically, in this embodiment of the invention, load-bearing pressure rods 406 are slidably installed at the four corners of the mounting frame 3, and the load-bearing pressure rods 406 are installed on the load-bearing frame 404; in addition, load-bearing springs 407 are installed at the four corners of the mounting frame 3, and the load-bearing springs 407 are installed on the load-bearing frame 404, and protective sleeves 408 are installed on the mounting frame 3 and the load-bearing frame 404. It should be noted that, in this embodiment of the invention, when a car or engineering vehicle loses control and moves towards the power distribution cabinet 1, it first presses on the load-bearing frame 404, causing the load-bearing frame 404 to move on the mounting frame 3 through the four load-bearing pressure rods 406, and causing the four load-bearing springs 407 to move downward under force.

[0054] Please continue to refer to the instruction manual appendix. Figures 2-8 More specifically, in this embodiment of the invention, a sealing limit strip 420 is installed on the inner wall of the temporary protection box 2. The sealing limit strip 420 is used to restrict the position of the L-shaped flip plate 401. It should be noted that in this embodiment of the invention, when the L-shaped flip plate 401 drives the power distribution cabinet 1 to rotate into the temporary protection box 2, it is blocked by the sealing limit strip 420, so that the power distribution cabinet 1 is suspended in the temporary protection box 2.

[0055] Please refer to the instruction manual attached. Figure 2 and Figures 6-8 More specifically, in this embodiment of the invention, lifting slides 503 are slidably installed inside both load-bearing brackets 409. Both lifting slides 503 are mounted on the top guard plate 410, and connecting slides 411 are mounted on both lifting slides 503. Lifting springs 504 are installed on the bottom side of the lifting slides 503, and the lifting springs 504 are mounted on the inner wall of the load-bearing brackets 409. It should be noted that in this embodiment of the invention, when the lifting slides 503 are unlocked, the lifting springs 504 cause the lifting slides 503 to move. The movement of the lifting slides 503 causes the connecting slides 411 to move. The connecting slides 411, through the connecting socket 414, cause the power distribution cabinet 1 and the lifting slides 509 to move upwards, thereby achieving the purpose of automatically raising the power distribution cabinet 1.

[0056] More specifically, in this embodiment of the invention, wedge-shaped drive frames 502 are movably installed on both load-bearing brackets 409, and limiting slots 505 are opened on both lifting slides 503, with the two wedge-shaped drive frames 502 respectively inserted into the two limiting slots 505;

[0057] Furthermore, two synchronous driving plates 506 are installed on the top side of the lifting float plate 501, and a synchronous push shaft 507 is installed between the two synchronous driving plates 506. It should be noted that, in this embodiment of the invention, the lifting float plate 501 floats due to the rise in water level, thereby driving the two synchronous driving plates 506 to move. The movement of the two synchronous driving plates 506 drives the synchronous push shaft 507 to move, and the synchronous push shaft 507 synchronously squeezes the two wedge-shaped drive frames 502 to move, causing the two wedge-shaped drive frames 502 to disengage from the two limiting slots 505, thereby achieving the purpose of automatically unlocking the lifting slide 503.

[0058] Please refer to the instruction manual attached. Figure 2 and Figures 9-11 Furthermore, the power supply equipment for tunnel construction provided in this embodiment of the invention, the automatic linkage cleaning device 7 also includes two downward driving frames 703, the two downward driving frames 703 are slidably installed on both sides of the load-bearing frame 404, the top side of the downward driving frame 703 is rotatably installed with a linkage rotating rod 702, and the linkage cleaning frame 701 is installed on the linkage rotating rod 702.

[0059] Furthermore, both sides of the load-bearing frame 404 are provided with downward pressure grooves 708, and two downward pressure drive frames 703 are slidably installed in the two downward pressure grooves 708 respectively. An upward push spring 709 is installed on the inner wall of the downward pressure groove 708 and is mounted on the downward pressure drive frame 703. It should be noted that, in this embodiment of the invention, the downward movement of the traveling plate 710 drives the two downward pressure drive frames 703 to move. The two downward pressure drive frames 703 move vertically within the two downward pressure grooves 708, causing the upward push spring 709 to contract. Then, under the rebound force of the upward push spring 709, the downward pressure drive frame 703 can move vertically up and down, thereby causing the linkage cleaning frame 701 to move vertically and thoroughly clean the filter plate 6.

[0060] More specifically, in this embodiment of the invention, a mounting groove 705 is provided on the pressing drive frame 703, a mounting shaft 706 is rotatably mounted in the mounting groove 705, a linkage rod 702 is mounted on the mounting shaft 706, and a limit block 704 is installed on the top side of the pressing drive frame 703. The limit block 704 is used to limit the position of the linkage rod 702.

[0061] Furthermore, a support torsion spring 707 is installed on the inner wall of the mounting slot 705, and the support torsion spring 707 is mounted on the mounting shaft 706. It should be noted that, in this embodiment of the invention, when the L-shaped flip plate 401 rotates, it drives the linkage cleaning frame 701 to rotate, which in turn drives the linkage rotating rod 702 to rotate. The linkage rotating rod 702 rotates within the mounting slot 705 via the mounting shaft 706, causing the support torsion spring 707 to be stressed. This achieves the purpose that when the L-shaped flip plate 401 rotates, the linkage cleaning frame 701 does not affect the rotation of the L-shaped flip plate 401. At the same time, the position of the linkage rotating rod 702 is limited by the limiting block 704, so that the linkage rotating rod 702 can remain perpendicular to the power distribution cabinet 1.

[0062] Please continue to refer to the instruction manual appendix. Figure 2 and Figures 9-11 More specifically, in this embodiment of the invention, a traveling 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 traveling plate 710. It should be noted that, in this embodiment of the invention, when a car or engineering vehicle passes in front of the power distribution cabinet 1, it first contacts and presses against the auxiliary rotating plates 711, allowing the car or engineering vehicle to smoothly move onto the traveling plate 710.

[0063] In summary, the working principle of the power supply equipment for tunnel construction provided in this embodiment of the invention is as follows:

[0064] When the power distribution cabinet 1 is installed in the tunnel, if a car or engineering vehicle loses control and moves toward the power distribution cabinet 1, it will first press on the load-bearing frame 404, causing the load-bearing frame 404 to move on the mounting frame 3 through the four load-bearing pressure rods 406, and causing the four load-bearing springs 407 to move downward under force. The downward movement of the load-bearing frame 404 will cause the two L-shaped push brackets 405 to move downward, which will then cause the L-shaped push brackets 405 to squeeze the flip push rod 403 to rotate. The flip push rod 403 will drive the L-shaped flip plate 401 to rotate through the flip shaft 402. The rotation of the L-shaped flip plate 401 will drive the two power distribution cabinets 1 to rotate. The rotation of the power distribution cabinets 1 will cause the two connecting sockets 414 to disengage from the two connecting slots 415, thereby causing the power distribution cabinets 1 to rotate into the temporary protection box 2 and be blocked by the sealing limit strip 420. This will cause the power distribution cabinets 1 to be suspended in the temporary protection box 2, preventing the power distribution cabinets 1 from being impacted.

[0065] In addition, it should be noted that when the L-shaped flip plate 401 rotates, it drives the protective airbag 412 to rotate, which in turn causes the airbag cable 413 to be pulled out. At this time, the protective airbag 412 explodes, allowing the car or engineering vehicle to collide with the protective airbag 412. This can further prevent the power distribution cabinet 1 from collapsing, and at the same time effectively protect the car or engineering vehicle. Furthermore, if a rockfall occurs in the tunnel and the rockfall is large, it can hit the top guard plate 410, which in turn causes the top guard plate 410 to move the two load-bearing brackets 409. This, in turn, causes the load-bearing brackets 409 to move the load-bearing frame 404, thus achieving the same purpose of flipping the power distribution cabinet 1 into the temporary protection box 2.

[0066] Furthermore, when water accumulates in the tunnel, the lifting floating plate 501 rises due to the rising water level, which in turn moves the two synchronous driving plates 506. The movement of the two synchronous driving plates 506 moves the synchronous push shaft 507, which in turn squeezes the two wedge-shaped driving frames 502, 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 springs 504 move the lifting slide 503. The movement of the lifting slide 503 moves the connecting slide 411. The connecting slide 411 moves the power distribution cabinet 1 and the rising slide 509 upward through the connecting socket 414. The rising slide 509 moves vertically upward in the rising slide groove 508, thereby achieving the purpose of moving the power distribution cabinet 1 upward when the water level rises, avoiding the problem of the power distribution cabinet 1 being submerged in water.

[0067] Furthermore, when a car or engineering vehicle passes in front of the power distribution cabinet 1, it can be moved onto the traveling plate 710 by the auxiliary rotating plate 711 and pressed down on the traveling plate 710. The downward movement of the traveling plate 710 drives the two downward pressing drive frames 703 to move. The two downward pressing drive frames 703 move vertically in the two downward pressing grooves 708 and cause the upward pushing spring 709 to contract. At the same time, the movement of the two downward pressing drive frames 703 drives the two linked cleaning frames 701 to move through the two linked rotating rods 702. It should be noted that when the car or engineering vehicle drives away from the auxiliary rotating plate 711, the rebound force of the two upward springs 709 drives the two downward pressing drive frames 703 to move upward. This causes the downward pressing drive frames 703 to drive the linkage cleaning frame 701 to move upward through the linkage rotating rod 702, realizing the vertical movement of the linkage cleaning frame 701, thereby fully cleaning the filter plate 6 and achieving the purpose of automatic cleaning of the filter plate 6. In addition, when the L-shaped flip plate 401 rotates, it drives the linkage cleaning frame 701 to rotate. The linkage cleaning frame 701 drives the linkage rotating rod 702 to rotate. The linkage rotating rod 702 rotates in the mounting groove 705 through the mounting shaft 706, and causes the support torsion spring 707 to be stressed. Therefore, when the L-shaped flip plate 401 rotates, the linkage cleaning frame 701 does not affect the rotation of the L-shaped flip plate 401.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
