[0035] During use, the device is moved to the track of rail transit, and the device is stably installed on the track surface through the use of the moving mechanism 4. Then, with the cooperation of the moving mechanism 4, the device will move stably along the track, and during the movement, the existing detection camera, lighting and control panel installed in the controller body 2 are used to take pictures of the situation in the track, so that the subsequent staff can formulate corresponding strategies according to the water accumulation in the track. Then, with the cooperation of the extraction pump body 3 and the suction mechanism 5, the accumulated water in the track is extracted, and the extended pipe installed by the staff is used to directly transport the accumulated water in the track to the drainage channel and sewer, so as to complete the rapid treatment of the accumulated water in the track, thereby ensuring the stability of the equipment during operation, and eliminating the need for staff to manually move and install the drainage components, thereby improving the overall safety of the drainage process.

[0036] By the attached Figure 2 As shown, it is a structural schematic diagram of the moving mechanism 4 in this embodiment, the moving mechanism 4 includes a fixed base plate 41, an electric push rod 42, a moving shell 43 and a driving component 44, the fixed base plate 41 is fixedly installed on the lower surface of the support base 1, the electric push rod 42 is symmetrically fixedly installed on both sides of the fixed base plate 41, the moving shell 43 is installed at the output end of the electric push rod 42, and a driving component 44 for driving the support base 1 to move is installed inside the moving shell 43.

[0037] During use, the distance between the two groups of mobile shells 43 can be adjusted through the cooperation of the electric push rod 42 and the telescopic rods installed on both sides of the electric push rod 42, so that the mobile shell 43 and the driving component 44 can be stably fitted with the edge of the track, so that the driving component 44 can subsequently drive the entire device to move along the track, which is convenient for the suction mechanism 5 and the extraction pump body 3 to cooperate to quickly extract and process the accumulated water in the track, simplifying the steps of the overall operation of the equipment, and when in use, the driving component 44 can allow the equipment to be stably installed on the track, and will not shake randomly due to the impact of water flow, thereby ensuring the stability of the equipment during use.

[0038] By the attached Figure 3 and Figure 4 As shown, it is a schematic diagram of the structure of the driving component 44 in this embodiment, the driving component 44 includes a driving wheel 441, a linkage support rod 442, a meshing gear 443, a meshing belt 444 and a driving motor 445, the driving wheel 441 is equidistantly mounted on the bottom end of the fixed base plate 41, the linkage support rod 442 is fixedly mounted on the top of the driving wheel 441, the linkage support rod 442 is fixedly mounted on the outside of the linkage support rod 442, and a plurality of groups of meshing gears 443 are meshingly mounted on the outside with a meshing belt 444, the driving motor 445 is fixedly mounted on the upper surface of the movable shell 43, and the output end of the driving motor 445 is fixedly connected to the end of one group of linkage support rods 442.

[0039] During use, by moving the position of the movable shell 43 itself, the driving wheel 441 will fit with the edge of the track, and the groove of the driving wheel 441 itself is used to lock the overall position of the equipment. Then, under the drive of the driving motor 445, one group of linkage support rods 442 drives the meshing gears 443 and the driving wheel 441 corresponding to the group of linkage support rods 442 to rotate. At this time, with the cooperation of the meshing gears 443 and the meshing belts 444, multiple groups of meshing gears 443 work at the same speed and the same direction, so that multiple groups of driving wheels 441 can drive the stable movement of the components on the upper end of the support base 1, thereby realizing the stable movement of the equipment itself.

[0040] By the attached Figure 4 As shown, it is a schematic diagram of the structure of the driving component 44 in this embodiment. The driving component 44 also includes a cleaning slider 446, which is fixedly installed on the top of the moving shell 43. The cleaning slider 446 is provided with a fitting groove that fits with the side of the track.

[0041] During use, by installing the cleaning slider 446, when the driving assembly 44 moves along the track as a whole, the supporting base 1 will push the cleaning slider 446 to move synchronously, allowing the cleaning slider 446 to slide along the surface of the track, so that the cleaning slider 446 can push and clean the impurities, stones, etc. attached and attached to both sides of the track, thereby ensuring the cleanliness of the track, preventing the presence of impurities on the surface of the track from affecting the stability of the driving assembly 44 itself during operation, and improving the safety of the equipment during operation.

[0042] By the attached Figure 5 and Figure 6 As shown, it is a structural schematic diagram of the suction mechanism 5 in this embodiment, the suction mechanism 5 includes a water inlet pipe 51, a water extraction pipe 52, a rotating frame 53 and a limit assembly 54, the water inlet pipe 51 is installed on the side of the extraction pump body 3, and the water inlet pipe 51 is connected to the water inlet end of the extraction pump body 3, and two groups of water extraction pipes 52 are arranged, and the water extraction pipes 52 are installed at the end of the water inlet pipe 51. The side of the support base 1 is symmetrically equipped with a rotating frame 53 for adjusting the water inlet angle of the water extraction pipe 52, and the limit assembly 54 is rotatably installed at the end of the rotating frame 53.

[0043] During use, with the cooperation of the extraction pump body 3 and the water inlet pipe 51, the accumulated water extraction pipe 52 can quickly extract the accumulated water in the target area, and with the cooperation of the rotating frame 53, a limiting component 54 is installed at the end of the rotating frame 53. At this time, the rotating frame 53 as a whole will be tilted due to the imbalance of weight, and the limiting component 54 will shift into the track, so that the limiting component 54 can fit into the track as much as possible, so that the water suction port of the accumulated water extraction pipe 52 can fit more closely to the bottom of the accumulated water, making the overall extraction effect of the accumulated water extraction pipe 52 more stable and thorough.

[0044] By the attached Figure 7 As shown, it is a structural schematic diagram of the limit assembly 54 in this embodiment, the limit assembly 54 includes a limit cylinder 541, a matching mounting seat 542 and a movable roller 543, the limit cylinder 541 is rotatably mounted on the end of the rotating frame 53, the matching mounting seat 542 is fixedly mounted on the bottom of the limit cylinder 541, the accumulated water extraction pipe 52 is slidably connected to the limit cylinder 541, the matching mounting seat 542 is provided with a filter screen for filtering and extracting impurities in the wastewater, and the movable rollers 543 are symmetrically fixedly mounted on both sides of the matching mounting seat 542.

[0045] During use, the end of the water extraction pipe 52 is inserted into the limiting cylinder 541 to ensure that the end of the water extraction pipe 52 is in contact with the upper surface of the matching mounting seat 542. Then, through the operation of the extraction pump body 3, the water extraction pipe 52 will extract the accumulated water outside the matching mounting seat 542. At this time, the filter screen installed in the matching mounting seat 542 can filter the impurities in the accumulated water to prevent the granular impurities from entering the water extraction pipe 52 and damaging the inner wall of the water extraction pipe 52. In addition, when the equipment is moving, the matching mounting seat 5 Under the action of gravity and its own weight, 41 will deflect to the side close to the ground with the cooperation of the rotating frame. At this time, the movable rollers 543 pretending to be on both sides of the matching mounting seat 542 will move along the track surface, so that the matching mounting seat 542 can move up and down with the height of the track surface, so that the matching mounting seat 542 can always fit the ground, and the subsequent water extraction pipe 52 inserted into the limiting cylinder 541 can stably extract the accumulated water, thereby improving the working quality of the equipment itself and ensuring the stability of the equipment when extracting water.

[0046] By the attached Figure 7 As shown, it is a schematic diagram of the structure of the limit assembly 54 in this embodiment. The limit assembly 54 also includes a limit member 544, which is installed on the side of the limit cylinder 541. The limit member 544 is used to lock the position of the accumulated water extraction pipe 52 after it is inserted into the limit cylinder 541.

[0047] During use, through the use of the limit member 544, when the water extraction pipe 52 is inserted into the limit cylinder 541, the limit member 544 locks the position of the water extraction pipe 52 itself, so that the end of the water extraction pipe 52 can be stably fitted with the surface of the matching mounting seat 542, and the water extraction pipe 52 can stably extract water from the ground between the rails. When the equipment moves, although the limit assembly 54 will shake up and down, due to the existence of the limit member 544, the water extraction pipe 52 is still stably installed in the limit cylinder 541. The overall extraction effect of the subsequent water extraction pipe 52 is more stable, which ensures the stability of the equipment during operation and improves the overall work quality.

[0048] By the attached Figure 7 As shown, it is a structural schematic diagram of the limit assembly 54 in this embodiment, the limit member 544 is composed of a fixed block, a locking block, a pulling rod and a spring, the fixed block is fixedly installed on the side of the limit cylinder 541, the fixed block and the limit cylinder 541 are jointly provided with a sliding groove, the locking block is slidably installed in the sliding groove, the pulling rod is fixedly installed at the end of the locking block, the pulling rod is slidably connected to the fixed block, the spring is sleeved on the outside of the pulling rod, and when the locking block slides toward the side close to the accumulated water extraction pipe 52, the spring is in a released state.

[0049] When in use, the water extraction tube 52 is inserted into the limiting tube 541. During the insertion process, the end of the water extraction tube 52 squeezes the locking block, and the locking block automatically moves into the sliding groove. At this time, the spring is in a force storage state. When the water extraction tube 52 is inserted into the target position, the locking block automatically pops out under the action of the spring, locks the position of the water extraction tube 52 itself, and realizes rapid installation and plug-in of the pipeline. When the water extraction tube 52 is subsequently disassembled, it is only necessary to pull the pulling rod so that the pulling rod pulls the locking block to retract into the sliding groove. When the locking block slides into the sliding groove, the spring is in a force storage state. At this time, the locking block no longer squeezes the water extraction tube, and the water extraction tube can be pulled out from the limiting tube 541. Later, as the staff releases the pulling rod, the spring will release its accumulated elastic force to reset the locking block for subsequent reuse.

[0050] By the attached Figure 8 As shown, it is a structural schematic diagram of the output mechanism 6 in this embodiment. The emergency drainage device also includes an output mechanism 6, and the output mechanism 6 includes an output pipe 61, a pipe joint 62 and a support assembly 63. The output pipe 61 is installed at the water outlet end on the side of the extraction pump body 3, the pipe joint 62 is fixedly installed at the end of the output pipe 61, and the support assembly 63 is installed on the upper surface of the controller body 2.

[0051] During use, the output pipe 61 is used to install the output pipe 61 to the water outlet end of the extraction pump body 3. Then, through the cooperation of the output pipe 61 and the pipe joint 62, the staff connects the pipe of corresponding length to the pipe joint 62, so that after the overall equipment moves a certain distance, the extraction pump body 3 can still transport the accumulated water through the pipe. When in use, the support component 63 is used to support the position of the output pipe 61 and the pipe joint 62 to prevent the pipe joint 62 and the output pipe 61 from falling directly into the track under the action of gravity, affecting the safety and stability of the equipment during use.

[0052] By the attached Figure 8 As shown, the support assembly 63 is composed of a support frame and a rotating connecting rod. The rotating connecting rod is rotatably mounted on the upper surface of the controller body 2, and the support frame is rotatably mounted on the end of the rotating connecting rod.

[0053] During use, the support frame fits to the bottom end of the output pipe 61 to support the output pipe 61, and the use of the rotating connecting rod can adjust the position of the pipe joint 62, which is convenient for the staff to adjust the position of the pipe joint 62 according to the position of the sewer outlet and the length of the pipe connected to the pipe joint 62, thereby ensuring the stability of the component during use.

[0054] By the attached Fig. 9As shown, it is a structural schematic diagram of the alarm mechanism 7 in this embodiment. The emergency drainage device also includes an alarm mechanism 7 installed in the forward direction of the support base 1. The alarm mechanism 7 includes a side connecting shell 71, a circuit touch plate 72, a floating sphere 73 and a touch switch 74. The side connecting shell 71 is symmetrically installed on both sides of the support base 1, the circuit touch plate 72 is slidably installed inside the side connecting shell 71, the floating sphere 73 is installed on the side of the circuit touch plate 72, and the touch switch 74 is fixedly installed on the upper surface of the side connecting shell 71, and the touch switch 74 is electrically connected to the controller body 2.

[0055] During use, when the equipment moves to the wading area along the track, the floating sphere 73 adjusts its own height according to the water level under the action of the buoyancy of the water, so that the circuit touch plate 72 slides inside the side connecting shell 71. When the water level reaches the target threshold, the circuit touch plate 72 fits with the touch switch 74. At this time, the touch switch 74 will send out an alarm signal. Under the action of the controller body 2, it reminds the staff that the water level in the current area is high and the equipment cannot enter stably. It is necessary to lower the water level after dealing with the overflowed water in the current area before continuing to move forward, which plays a warning role, thereby ensuring the safety and stability of the equipment during operation.

[0056] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
