Description

Technical Field

[0001] This invention relates to the field of drainage unit technology, specifically a self-lifting and pushable rapid drainage unit. Background Technology

[0002] As is well known, waterlogging control in confined and complex spaces such as underground utility tunnels, civil defense projects, and underground parking garages is a core task for urban flood control, drainage, and the safe operation and maintenance of underground facilities. It places stringent requirements on the spatial adaptability, positioning accuracy, operational stability, and continuous operation efficiency of drainage equipment.

[0003] However, conventional drainage equipment is mostly a fixed, integrated structure, which is too large to fit into narrow spaces such as pipe corridors and air-raid shelters. Even if smaller equipment can fit, it lacks flexible movement and precise alignment, making it difficult to connect to scattered water accumulation points. Some equipment with folding bases can reduce the size and fit the space, but due to insufficient rigidity at the folding point, the vibration generated by the pump operation can cause the folding part to misalign and loosen, making it unable to stably support the equipment. Moreover, there is no reliable locking mechanism after precise alignment, and the equipment is prone to deviating from the water accumulation point due to vibration, resulting in insufficient water intake and low drainage efficiency. After the equipment is locked, the overall structure is completely fixed, which cannot adapt to scenarios with varying elevations, such as water accumulation on the slope of pipe corridors or stepped water accumulation in air-raid shelters. The water inlet cannot fit the water surface at different heights, and low-level water cannot be completely drained. At the same time, existing equipment generally uses a combination of fixed guide pipes and simple filters. Simple filters can only intercept large particles of debris and cannot block fibrous debris. After the fibers become entangled in the filter, there is no automatic peeling and cleaning structure, which requires frequent shutdowns for disassembly and cleaning, seriously interrupting drainage operations and reducing overall drainage efficiency.

[0004] Therefore, a self-lifting and pushable rapid drainage unit is needed. Summary of the Invention

[0005] In order to overcome the problems of existing self-lifting and pushable rapid drainage units lacking flexible pushing and precise alignment structure, easy equipment deviation from water accumulation point due to vibration, and frequent shutdown for disassembly and cleaning, the present invention provides a self-lifting and pushable rapid drainage unit.

[0012] Furthermore, based on the aforementioned solution, a bottom cylinder is fixedly installed on the other side of the top of the base, and a sleeve rod is slidably installed inside the bottom cylinder, with the top of the sleeve rod fixedly installed to the bottom of the mounting plate.

The push handle 52 is for the operator to hold and drive the entire device to move.

[0042] First, refer to Figure 1 In this embodiment, the sliding plate 10 of the folding component 8 slides along the sliding groove 9, causing the baffle 11 and the rotating wheel 13 to unfold or retract. The motor 17 drives the rotating plate 18 to rotate, and the baffle 11 moves through the first rotating rod 16, thereby realizing the folding and unfolding of the rotating wheel 13, reducing the overall volume of the device, and adapting to movement in narrow spaces.

[0043] Then, refer to Figure 9 In this embodiment, the hydraulic rod 20 drives the lifting plate 21 to move vertically, causing the vertical plate 23 to slide along the vertical groove 22, so that the fixed plate 24 and the anti-slip point 25 touch the ground and form a locking structure, increasing the frictional resistance between the device and the ground, and preventing the device from shifting due to vibration during the operation of the water pump 4.

[0044] Secondly, see Figure 10 In this embodiment, the bidirectional lead screw 33 of the lifting assembly 2 rotates to drive the moving block 32 to move, so that the first lifting rod 27 and the second lifting rod 29 rotate in opposite directions, pushing the lifting plate 31 and the mounting plate 3 to rise and fall, adjusting the height of the water pump 4 and the water pipe 7 to adapt to water accumulation scenarios with different height differences.

[0045] Again, see Figure 2 In this embodiment, the slide rail 37 on the auxiliary plate 35 cooperates with the slider 38 to drive the support frame 39 and the water pipe 7 to slide, adjust the position of the water inlet end of the water pipe 7, so that the water pipe 7 can fit the water surface of different water levels, and improve the drainage effect of low water level water accumulation.

[0046] In addition, see Figure 9 In this embodiment, the bottom cylinder 40 and the sleeve rod 41 cooperate with the lifting action of the mounting plate 3 to guide both sides of the mounting plate 3, so as to prevent the mounting plate 3 from tilting during the lifting process and ensure the smooth operation of the water pump 4 and the water storage tank 5.

[0047] In addition, see Figure 8 In this embodiment, the screen 49 at the front end of the pumping pipe 7 performs preliminary filtration, and the screen 43 inside the pumping pump 4 performs secondary filtration. Turning the handle 45 drives the brush 46 to rotate, cleaning the fiber debris on the surface of the screen 43. There is no need to stop the machine to disassemble, and the drainage operation is kept continuous.

[0048] In addition, see Figure 5 In this embodiment, the protective cover 19 completely encloses the motor 17, the rotating plate 18 and the first rotating rod 16 to prevent water and debris from entering the transmission components, prevent jamming and corrosion of the transmission components, and extend the service life of the folding assembly 8.

[0049] Finally, see Figure 3 In this embodiment, the water storage tank 5 receives the water discharged by the water pump 4 through the delivery pipe 6, the valve 50 controls the water discharge, and the push handle 52 makes it convenient for the operator to hold the pushing device and flexibly connect to different water accumulation points.

[0050] Working principle: When using this self-lifting and movable rapid drainage unit, first move the device to the entrance of a narrow space that needs drainage, such as an underground pipe gallery, civil defense project, or underground garage. The operator holds the push handle 52 and drives the device to move as a whole through the rotating wheels 13 on both sides of the baffle 11. The rotating wheels 13 roll along the ground, allowing the device to smoothly enter the narrow space. During the movement, the sliding plate 10 remains extended along the sliding groove 9, and the baffle 11 and rotating wheels 13 are in the unfolded position to ensure that the device moves smoothly.

[0051] After the device is moved to the vicinity of the designated water accumulation point, the motor 17 at the bottom of the base 1 is started. The output shaft of the motor 17 rotates, causing the rotating plate 18 to rotate in a circle. When the rotating plate 18 rotates, it pulls the first rotating rods 16 at both ends. The first rotating rods 16 rotate around the rotating column 15. At the same time, the first rotating rods 16 slide along the slide groove 14. The first rotating rods 16 pull the rotating column 15 and the baffle 11 to move towards the center of the base 1. The baffle 11 drives the sliding plate 10 to slide inward along the sliding groove 9. The rotating wheels 13 on both sides of the baffle 11 gradually retract as the baffle 11 moves. The rotating wheels 13 are no longer in contact with the ground. After the baffle 11 moves to the designated position, the motor 17 is turned off, and the folding and storage of the rotating wheels 13 is completed.

[0052] After the rotating wheel 13 is folded, the hydraulic rod 20 at the top of the base 1 is activated. The output shaft of the hydraulic rod 20 extends upward, driving the lifting plate 21 to move upward. The lifting plate 21 drives the vertical plates 23 on both sides to slide upward along the vertical groove 22 of the baffle 11. The vertical plates 23 drive the bottom fixing plate 24 and anti-slip point 25 to move upward synchronously. After the rotating wheel 13 is completely retracted, the output shaft of the hydraulic rod 20 is controlled to retract downward. The lifting plate 21 drives the vertical plates 23 to slide downward along the vertical groove 22. The fixing plate 24 and anti-slip point 25 move downward until the anti-slip point 25 is in close contact with the ground. The hydraulic rod 20 stops running. The fixing plate 24 and anti-slip point 25 form a support and locking structure, fixing the entire device in the current position to prevent the device from shifting due to vibration generated by the subsequent operation of the water pump 4.

[0053] After the device is fixed, adjust the height of the lifting component 2 according to the water level and terrain difference at the water accumulation point. The operator holds the crank 34 and rotates it. The crank 34 drives the bidirectional lead screw 33 to rotate synchronously. The rotation of the bidirectional lead screw 33 drives the two sets of moving blocks 32 to slide in opposite directions. The moving blocks 32 drive the rotating shaft 30 to move. The rotating shaft 30 drives the first lifting rod 27 and the second lifting rod 29 to rotate around the intersection point. The bottom end of the first lifting rod 27 rotates along the base frame 26, and the bottom end of the second lifting rod 29 slides along the transverse groove 28 of the base frame 26. The intersection angle of the first lifting rod 27 and the second lifting rod 29 increases, pushing the top lifting plate 31 to move upward. The lifting plate 31 drives the mounting plate 3 to rise and fall upward. The mounting plate 3 drives the water pump 4, the water storage tank 5 and the water pumping pipe 7 to rise synchronously.

[0054] Turning the crank handle 34 in the opposite direction causes the two sets of moving blocks 32 to slide in opposite directions, reducing the angle between the first lifting rod 27 and the second lifting rod 29. The lifting plate 31 then causes the mounting plate 3 to fall downwards. After adjusting to the height at which the water inlet end of the pumping pipe 7 can touch the water surface, stop turning the crank handle 34 to complete the height adjustment. During the lifting and lowering of the mounting plate 3, the bottom sleeve rod 41 slides vertically along the bottom cylinder 40. The auxiliary plate 35 slides and engages with the side wall of the mounting plate 3 to guide the lifting and lowering of the mounting plate 3 and keep the mounting plate 3 horizontal and stable.

[0055] After the height adjustment is completed, adjust the water inlet position of the water pumping pipe 7. The operator pushes the support frame 39, which drives the slider 38 to slide along the slide rail 37 on the auxiliary plate 35. The slider 38 moves along the limiting groove 36, and the support frame 39 drives the water pumping pipe 7 to move synchronously, pushing the water inlet end of the water pumping pipe 7 to the center of the water accumulation position. The screen bucket 49 is completely immersed in the water, completing the alignment adjustment of the water pumping pipe 7.

[0056] Then, the water pump 4 is started. Under the suction of the water pump 4, the water first passes through the screen 49 for preliminary filtration. Large particles in the water are intercepted by the screen 49. The filtered water enters the water pumping pipe 7 and is transported to the inlet of the water pump 4. Before entering the water pump 4, the water passes through the screen 43 at the screening tank 42 for secondary filtration. Fine fibrous impurities in the water are intercepted by the screen 43. The filtered clean water is pressurized by the water pump 4 and transported to the water storage tank 5 through the delivery pipe 6 for storage.

[0057] During drainage operations, fibrous debris will gradually adhere to the surface of the screen 43. The operator does not need to stop the machine. Simply turn the rotating handle 45 on the outside of the water pump 4. The rotating handle 45 rotates around the handle groove 44, which drives the brush 46 inside the screening tank 42 to rotate synchronously. The bristles of the brush 46 continuously wipe the surface of the screen 43, peeling off the attached fibrous debris from the screen 43 to prevent the screen 43 from clogging. The soft pad 47 deforms flexibly with the rotation of the rotating handle 45, always covering the handle groove 44 to prevent water and debris from overflowing from the handle groove 44. The screen bucket 49 on the side of the water pump 7 continuously intercepts large particles of debris. The debris on the surface of the screen bucket 49 only needs to be cleaned periodically. There is no need to disassemble the water pump 7.

[0058] After the water in the water storage tank 5 has been stored to a certain amount, open the valve 50 on the side of the water storage tank 5 to discharge the water into the designated drainage pipe or collection area. After the discharge is completed, close the valve 50 and continue the water pumping operation. For multiple scattered water accumulation points, turn off the water pump 4, start the hydraulic rod 20 to move the fixed plate 24 and the anti-slip point 25 upward, start the motor 17 to unfold the rotating wheel 13, and hold the push handle 52 to push the device to the next water accumulation point. Repeat the above positioning, locking, height adjustment and drainage operations.

[0059] After the drainage operation is completed, stop the water pump 4, remove the water pipe 7 from the water accumulation area, turn the rocker handle 34 in the opposite direction to make the lifting component 2 fall back to the initial height, start the hydraulic rod 20 to retract the fixing plate 24 and anti-slip point 25, start the motor 17 to unfold the rotating wheel 13, and hold the push handle 52 to push the device out of the narrow space to complete the drainage operation.

[0060] When the device moves in a confined space, the folded rotating wheel 13 reduces the overall width of the device, allowing it to pass smoothly through narrow passages. The locked fixing plate 24 and anti-slip points 25 ensure stable operation of the device and prevent it from deviating from the water accumulation point due to vibration. The adjustable height adapts to water accumulation scenarios with different terrains such as steps and slopes. The dual filtration and self-cleaning structure prevents the filter screen from clogging, eliminating the need for frequent shutdowns for cleaning and maintaining a continuously efficient drainage state to meet the rapid drainage needs of confined underground spaces.

[0061] During operation, the protective cover 19 continuously protects the motor 17 and transmission components at the bottom, preventing water and sediment from entering and causing damage. The cooperation between the sliding groove 9 and the sliding plate 10 ensures that the rotating wheel 13 folds smoothly. The cooperation between the vertical groove 22 and the vertical plate 23 ensures that the fixed plate 24 rises and falls stably. The cooperation between the slide rail 37 and the slider 38 ensures that the water pumping pipe 7 is adjusted accurately. All components work together to realize the device's functions of self-lifting, pushing, rapid drainage, and self-cleaning and anti-clogging. It is suitable for flood control, drainage and waterlogging management operations in various narrow and complex spaces such as underground pipe corridors, civil defense projects, and underground garages.
