Detailed Implementation

[0055] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments.

[0056] like Figures 1 to 14 As shown, a water-blocking device for the ventilation shaft opening 3 of a subway station is installed at the ventilation shaft opening 3. A sealing door panel stacking area 2 for storing sealing door panels 1 is provided on one side of the ventilation shaft opening 3. The water-blocking device for the ventilation shaft opening 3 of the subway station includes a guide rail system 58 and a transport system 57.

[0057] The guide rail system 58 includes guide rails 15 respectively laid on the two opposite outer sides of the ventilation shaft opening 3, and the guide rails 15 extend from the ventilation shaft opening 3 to the blocking door panel stacking area 2.

[0058] The transport system 57 includes a transport device that drives the blocking door panel 1 to move along the guide rail 15. The transport device includes a lifting mechanism, a traveling mechanism and a control unit. The lifting mechanism is mounted on the traveling mechanism. The control unit is used to control the lifting mechanism to adjust the horizontal height of the blocking door panel 1 and to control the traveling mechanism to adjust the moving position of the blocking door panel 1.

[0059] When not in use, the blocking door panel 1 is placed in the blocking door panel stacking area 2;

[0060] During operation, the control unit controls the lifting mechanism to make the height of the sealing door panel 1 consistent with the height of the well frame 7 of the ventilation shaft opening 3. The control unit controls the traveling mechanism to move the sealing door panel 1 from the sealing door panel stacking area 2 to the designated position to seal the ventilation shaft opening.

[0061] In this invention, the sealing door panel 1 is placed in the sealing door panel stacking area 2 beforehand. The lifting mechanism in the transport system 57 lifts the sealing door panel 1 to the same height as the well frame 7 of the ventilation shaft opening 3. Then, the traveling mechanism in the transport system 57 transports the sealing door panel 1 to the ventilation shaft opening 3 via the guide rail system 58. Finally, the lifting mechanism places the sealing door panel 1 into the ventilation shaft opening 3 to achieve the effect of sealing the ventilation shaft opening 3 with the sealing door panel 1.

[0062] In addition, the present invention also includes a control unit, which comprises a control box 22, an operation control box, and a PLC. The PLC is housed in the control box 22 and has a preset control program. The control program controls the start, stop, and running path of the lifting mechanism and the traveling mechanism. The operator can control the control unit through the operation control box.

[0063] In some embodiments of the present invention, the door panel stacking area 2 includes a storage rack 5, and the storage rack 5 is equipped with a cover 4. The cover 4 and the storage rack 5 extend the service life of the present invention and ensure its stability during use.

[0064] In detail, the present invention has a sealing and / or water-blocking function, and the transportation of multiple sealing door panels 1 is achieved by the corresponding lifting mechanism and walking mechanism to achieve smooth and fast handling.

[0065] The normal state is defined as the state in which the ventilation shaft opening 3 does not need to be sealed. That is, when not in operation, the sealing door panel 1 is stacked in the sealing door panel stacking area 2 and protected by the storage rack 5 and the covering shed 4.

[0066] Meanwhile, the well frame 7 is pre-embedded and fixed at the ventilation shaft opening 3. Sealing strips and fixing and / or positioning components adapted to the sealing door panel 1 are installed on the well frame 7 for subsequent installation and sealing operations of the sealing door panel 1. The sealing door panel 1 is also equipped with a door panel support 46. When the sealing door panel 1 is placed on the well frame 7, it is positioned on the well frame 7 via the door panel support 46.

[0067] The sealing door panel stacking area 2 is located adjacent to the ventilation shaft opening 3 to facilitate the storage and transportation of the sealing door panels 1.

[0068] The movement trajectory, speed curve, and starting and ending points of each sealing panel 1 on the guide rail 15 driven by the transport system 57 are all controlled by the control unit, ensuring that the entire sealing conversion process is convenient, accurate, and efficient, significantly improving the automation level and operational reliability of the invention. As a specific embodiment of the invention, the time from initiation to complete sealing does not exceed 5 minutes, ensuring rapid response in emergency situations.

[0069] In some embodiments of the present invention, the sealing door panel 1 includes a sealing door panel 1 body, the sealing door panel 1 body is a steel beam plate structure, an annular pressing plate 36 is provided around the inner panel, and a rubber pad 13 is provided on the inner side of the sealing door panel 1.

[0070] The sealing door panel 1 includes an initial sealing door panel 1, at least one intermediate sealing door panel 1 and a final sealing door panel 1. The initial sealing door panel 1 and the intermediate sealing door panel 1 are also provided with a center seam adhesive strip groove 20 at the end near the sealing door panel stacking area 2.

[0071] Each sealing door panel 1 is associated with a control unit, which controls the movement path of each sealing door panel 1.

[0072] In detail, in this invention, when the sealing door panels 1 are stacked in the sealing door panel stacking area 2, the sealing door panel 1 at the bottom is the final sealing door panel 1, the sealing door panel 1 at the top is the initial sealing door panel 1, and the sealing door panel 1 between the initial sealing door panel 1 and the final sealing door panel 1 is the intermediate sealing door panel 1. When the sealing door panels 1 are placed on the well frame 7 to seal the ventilation shaft opening 3, the sealing door panel 1 furthest from the sealing door panel stacking area 2 is the initial sealing door panel 1, and the sealing door panel 1 closest to the sealing door panel stacking area 2 is the final sealing door panel 1.

[0073] The sealing strips of each sealing door panel 1 and the well frame 7, as well as the sealing strips of the middle seams between adjacent sealing door panels 1, work together to achieve the effect of squeezing the sealing strips to improve the sealing effect.

[0074] A center seam rubber strip groove 20 is set in the middle gap between the sealing door panels 1. The sealing strip and the embedded pressure plate structure effectively prevent gas and moisture leakage, provide good buffering and sealing protection, improve the sealing performance of the ventilation shaft, and enhance its stability and durability under various environmental conditions.

[0075] Preferably, the sealing door panel 1 is a steel beam plate structure, using a 5mm thick high-strength panel to ensure its stability and durability under heavy loads. The frame of the sealing door panel 1 is welded from high-quality channel steel and I-beams, which not only provides excellent load-bearing capacity but also enhances the rigidity of the overall structure. The sealing door panel 1 has sufficient strength and rigidity to cope with various extreme working conditions.

[0076] Furthermore, a support steel plate 35 is provided on the well frame 7, the support steel plate 35 is arranged along the circumference of the well frame 7, and a rubber strip groove 20 is provided on the support steel plate 35;

[0077] Angle steel 25 is provided at the corner of the supporting steel plate 35; a first positioning component 11 and a first fixing component 9 are provided on the supporting steel plate 35; when the sealing door plate 1 reaches the designated position, the first positioning component 11 is adapted to and connected with the second positioning component 12 on the sealing door plate 1, and the first fixing component 9 and the second fixing component 10 provided on the sealing door plate 1 lock the sealing door plate 1 onto the well frame 7.

[0078] As a specific embodiment of this implementation, the first positioning component 11 and the second positioning component 12 are respectively a positioning post and a positioning groove adapted to the positioning post, and the first fixing component 9 and the second fixing component 10 are respectively a latch and a latch seat.

[0079] In detail, a highly efficient positioning mechanism is employed during the precise alignment of the sealing door panel 1 and the well frame 7. Matching positioning posts and positioning slots are respectively set on the sealing door panel 1 and the well frame 7. Each sealing door panel 1 is equipped with positioning posts at its four corners, which can be precisely inserted into the positioning slots of the well frame 7 during installation. This ensures that the sealing door panel 1 is accurately installed in place, avoids the cumulative effect of installation deviation on the overall sealing effect of the ventilation shaft, and enables the sealing door panel 1 to be quickly aligned and locked, while maintaining structural stability and reliability.

[0080] Precision-machined locking seats are set at the four corners of the sealing door panel 1, perfectly matching the locking buckles. After installation, the operator inserts the locking buckles into the locking seats, which can quickly and tightly lock the sealing door panel 1 to the well frame 7, simplifying the installation process, improving work efficiency, ensuring a tight fit between the sealing door and the well frame 7 and the sealing door panel 1, and greatly improving the sealing performance of the ventilation shaft opening 3.

[0081] As a specific embodiment of the present invention, the sealing of the sealing gate panel 1 and the well frame 7 adopts a sealing strip and pressure plate structure to ensure high airtightness and watertightness. The sealing strip is made of high-quality elastic material, such as ethylene propylene diene monomer (EPDM) rubber, which has excellent weather resistance, heat resistance, and chemical resistance, and its aging resistance and sealing performance meet high standards. The pressure plate design allows the sealing gate panel 1 to fit tightly into the well frame 7, enhancing the sealing effect.

[0082] In some embodiments of the present invention, the walking mechanism includes a transport trolley 6, the bottom of which is provided with wheels 24, which move on a guide rail 15.

[0083] The transport trolley 6 includes a frame 19, which includes transport supports respectively set on two tracks and crossbeams 45 connected to the upper part of the two transport supports; each transport support is provided with a first drive mechanism, which is connected to the wheel 24 and drives the wheel 24 to run; the crossbeam 45 is provided with a second drive mechanism, which drives the lifting mechanism to start and stop.

[0084] In this embodiment, each wheel 24 is equipped with a guide roller 17, and each guide roller 17 is connected to the control unit to run along a predetermined trajectory.

[0085] In this embodiment, each first drive mechanism includes a servo motor 26. The drive shaft 28 of the servo motor 26 is connected to the driving gear of the transition gear set 33 via a coupling 29. The driven gear of the transition gear set 33 drives the drive gear 34 to rotate. A guide rack 16 is provided on the guide rail 15, and the guide rack 16 meshes with the drive gear 34. That is, in this invention, the drive gear 34 is driven to rotate by the servo motor 26, and the drive gear 34 meshes with the guide rack 16 on the guide rail 15 to achieve the effect of the transport trolley 6 moving on the guide rail 15.

[0086] The first drive mechanism also includes a gear mounting base 31, a transition gear set 33 and a drive gear 34 are both mounted on the gear mounting base 31, and a hinge 32 is provided on the gear mounting base 31. The hinge 32 allows the gear mounting base 31 to rotate flexibly to accommodate the smooth travel of the transport trolley 6 on the guide rail 15.

[0087] Furthermore, the gear mounting base 31 is provided with a compression spring 30 for pressing and providing preload to the drive gear 34, so as to ensure tight meshing between the drive gear 34 and the guide rack 16.

[0088] In this embodiment, the lifting mechanism includes a second drive mechanism and a lifting unit;

[0089] The second drive mechanism includes a power source, which is mounted on the crossbeam 45 and connected to the second drive mechanism.

[0090] Two lifting units are respectively set on a transport bracket, and each transport bracket is provided with a trolley track 44 arranged along the direction of the transport bracket;

[0091] Each lifting unit includes a lifting trolley 43, a lifting support 8, a lifting chain 42, a hydraulic cylinder 41, a lifting pulley 47, a chain connecting seat 48, and a chain fixing seat 49;

[0092] The chain connecting seat 48 and the lifting support 8 are respectively installed on the lifting trolley 43; the hydraulic cylinder 41 includes a cylinder body and a piston rod that extends and retracts within the cylinder body, and the piston rod extends and retracts relative to the cylinder body in the vertical direction. The end of the piston rod is provided with a lifting pulley 47, and the lifting pulley 47 includes a lifting pulley 47 groove.

[0093] The chain fixing seat 49 is located at the lower part of the cylinder body. One end of the lifting chain 42 is fixed on the chain fixing seat 49, and the other end is located on the chain connecting seat 48. The middle section of the lifting chain 42 is arranged around the pulley groove.

[0094] When the piston rod extends upward, it pushes the lifting pulley 47 to extend upward, and the lifting chain 42 drives the chain connecting seat 48, the lifting trolley 43 and the lifting support 8 to rise.

[0095] In detail, in this invention, when the piston rod extends upward relative to the cylinder body, it pushes the lifting pulley 47 to rise. At this time, since the lifting chain 42 is set in the pulley groove of the lifting pulley 47, the lifting pulley 47 pushes the lifting chain 42 to drive the chain connecting seat 48 and the lifting support 8 to rise, and pushes the lifting trolley 43 to rise in the trolley track 44, thereby achieving the effect of lifting the blocking door panel 1. When the piston rod of the hydraulic cylinder 41 performs telescopic movement, it drives the lifting chain 42 to move. Since the lifting chain 42 is connected to the lifting trolley 43, the movement of the lifting chain 42 enables the lifting trolley 43 to achieve the lifting function.

[0096] In this invention, a lifting chain 42 is connected to a lifting trolley 43 to achieve linkage with the trolley. The middle part of the chain rests in the pulley groove at the top of the hydraulic cylinder.

[0097] The lifting pulley 47 is configured to function like a movable pulley. Utilizing the unique mechanical transmission principle of the lifting pulley 47, the lifting chain 42 can move at twice the speed of the hydraulic cylinder 41. This speed-enhancing mechanism effectively accelerates the lifting speed of the lifting trolley 43, thereby significantly improving the overall efficiency of the lifting system.

[0098] Secondly, to improve the system's adaptability in flood-prone environments, the servo motor 26 and other electrical components are all installed at a height of at least 1 meter above the ground, effectively preventing direct damage to the electrical equipment from floodwaters and further enhancing the overall stability and reliability of the system.

[0099] Third, the frame 19 of the transport vehicle 6 is made of high-strength square tubes and other high-quality profiles welded together. Its structural design has been optimized according to the size of the sealing door panel 1 to ensure that the size of the frame 19 is perfectly matched with the sealing door panel 1, providing a stable and reliable load-bearing platform for the sealing door panel 1.

[0100] Fourth, a stop 14 is provided at the end of the guide rail 15 to prevent the transport trolley 6 from detaching from the guide rail 15. Correspondingly, a collision-resistant rubber block 18 is also provided at the front of the transport trolley 6, which can collide with the stop 14 to buffer the power of the transport trolley 6.

[0101] Furthermore, the coupling 29 in the first drive mechanism is a telescopic universal coupling 29, which can effectively compensate for relative displacement caused by vibration, impact, etc., so that the meshing of the gears and guide rail racks 16 always maintains an appropriate buffer margin when the trolley moves, further improving the reliability and durability of operation. A reducer 27 is also connected between the coupling 29 and the servo motor 26.

[0102] Furthermore, the gear mounting base 31 is provided with a compression spring 30 for pressing and providing preload to the drive gear 34, so as to ensure tight meshing between the drive gear 34 and the guide rack 16.

[0103] In detail, as a specific embodiment of the present invention, the transport trolley 6 adopts a four-wheel structure, that is, it includes four rollers, which allows the transport trolley 6 to move smoothly horizontally along the guide rail 15. Furthermore, to prevent the transport trolley 6 from derailing, each roller is equipped with a guide roller 17, and each guide roller 17 can be connected to a control unit, which enables it to run safely and smoothly along a predetermined trajectory. First drive mechanisms are respectively installed on the frames 19 on both sides of the transport trolley 6. Synchronous drive of the transport trolley 6 is achieved through two first drive mechanisms, ensuring its stability and accuracy during movement. Moreover, the travel path of the transport trolley 6 is controlled by a PLC in the control unit, which assigns a specific path program to different blocking gate panels 1, thereby achieving automated operation.

[0104] In addition, the mounting base can be flexibly rotated within a certain range in the first drive mechanism via the hinge 32, which can effectively adapt to the slight deformation and unevenness of the guide rail 15.

[0105] In detail, in the lifting mechanism of the present invention, a micro hydraulic station 21 is used as a power source, and the synchronous operation of the second drive mechanism located on both sides of the transport trolley 6 is realized through the micro hydraulic station 2121.

[0106] In this invention, the lifting mechanism includes a pulley, which drives the lifting chain 42 to move. The speed at which the lifting chain 42 moves can reach twice the extension and retraction speed of the hydraulic cylinder 41, effectively improving the lifting efficiency.

[0107] The lifting trolleys 43 on both sides of the transport trolley 6 are driven by a single power unit to achieve synchronous operation. The miniature hydraulic station 21, as the power source, possesses high efficiency and stable performance characteristics. Its compact design allows it to be easily installed on top of the transport trolley 6, facilitating maintenance without affecting the overall layout of the trolley 6. Key components such as cylinders, chains, and pulleys are built into the lifting trolleys 43, forming a simple yet efficient transmission system.

[0108] By precisely controlling the hydraulic oil flow and pressure of the lifting trolleys 43 on both sides through the hydraulic synchronous flow divider valve, a fast and stable synchronous lifting motion is achieved, ensuring the levelness and stability of the blocking door 1 during the lifting process. This effectively avoids problems such as jamming or damage to the blocking door 1 that may be caused by asynchronous lifting, and provides a strong guarantee for the smooth progress of the sealing operation at the ventilation shaft entrance 3.

[0109] In some embodiments of the present invention, the sealed water-blocking device at the ventilation shaft opening 3 of the subway station is also equipped with a manual operation device 50 for transporting and operating the transport system 57.

[0110] The manual operating device 50 includes an oil tank 54. The oil tank 54 and the oil pump 55 form an oil circulation circuit through an oil inlet pipe 51 and an oil return pipe 52. The oil pump 55 is also externally connected to a foot pedal 53, which is connected to the oil pump 55 through a return spring 56. Preferably, the oil tank 54 is also provided with a handrail 59 so that the operator can maintain balance when alternately stepping on the foot pedal 53.

[0111] In detail, in the event of a power outage or electrical equipment failure, a manual emergency operation mode can be immediately activated. The operator manually pedals the 53-type hydraulic pump 55 to replace the electric drive unit, thereby realizing the lifting and opening / closing action of the sealing door panel 1.

[0112] Furthermore, the foot-operated hydraulic pump 55 adopts a dual-plunger hydraulic pump design and is equipped with a return spring 56. During operation, the user stands on the two pedals of the foot pedal 53 mechanism with both hands holding the handles 59, and uses their own weight to alternately step on the pedals to press the two pumps 55, which then alternately and continuously supply oil.

[0113] During operation, the two oil pumps 55 alternately supply oil, effectively ensuring the continuity and stability of the oil supply. Each plunger oil pump 55 is equipped with a hydraulic check valve at its outlet to ensure that the two oil pumps 55 do not interfere with each other when working alternately, preventing hydraulic oil backflow, thereby maintaining the stability of the system pressure and enabling the door panel to be raised and lowered smoothly and reliably.

[0114] In use, connect the inlet and outlet oil pipes of the oil pump 55 to the inlet and outlet oil pipes of the transport trolley 6. By stepping on the hydraulic pump 55, drive the lifting trolley 43 to raise the sealing door panel 1, thus detaching the sealing door panel 1 from the well frame 7. Then, push the transport trolley 6 back to the sealing door panel stacking area 2, preparing to place the sealing door panel 1 back into the stacking area 2. Next, step on the hydraulic pump 55 again to drive the lifting trolley 43 to slowly lower the sealing door panel 1 onto the stacking area 2, completing the retrieval of all sealing door panels 1.

[0115] In a specific embodiment of the present invention, the normal state is defined as the condition where the ventilation shaft opening 3 does not need to be sealed. In this state, the shaft frame 7 is pre-embedded and fixed to the ventilation shaft opening 3. The shaft frame 7 is provided with key structures such as the installation groove for the sealing strip 40 and the installation positioning groove for the sealing door panel, for subsequent installation and sealing operations of the sealing door panel. The guide rail 15 of the transport trolley 6 is laid on both sides of the ventilation shaft, connecting the ventilation shaft and the sealing door panel stacking area 2. This stacking area is set adjacent to the ventilation shaft opening for convenient storage and transportation of the sealing door panels. The sealing door panels 1 are horizontally stacked on a dedicated stacking rack in the stacking area, while the transport trolley 6 is parked in the stacking area.

[0116] When it is necessary to seal the ventilation shaft opening 3, the operator's operation shall include at least the following steps:

[0117] 1. First, turn on the power of the transport vehicle 6 and press the "Automatic Shutdown" button on the control panel. At this time, the transport vehicle 6 will automatically correct its origin position to ensure the accuracy and consistency of subsequent operations.

[0118] 2. After calibration, the transport trolley 6 moves to the stacking position of the sealing door panel. The lifting trolleys 43 on both sides of the trolley are activated, smoothly lifting the first sealing door panel off the stacking rack and raising it to a specific transport height to prepare for the transport of the sealing door panel.

[0119] 3. The traveling mechanism of the transport trolley 6 runs precisely along the guide rail 15 to the installation position of the initial sealing door panel 37 according to the pre-set program, ensuring that the initial sealing door panel 37 can be accurately positioned.

[0120] 4. After reaching the installation position, the lifting mechanism of the transport trolley 6 slowly lowers the sealing door panel to the corresponding installation position on the well frame 7, and makes the sealing door panel detach from the sealing door panel support 46, thus completing the installation of the initial sealing door panel 37.

[0121] 5. After the initial sealing door panel 37 is installed, the transport trolley 6 automatically returns to the sealing door panel stacking position to prepare for the transport of the next sealing door panel.

[0122] 6. The transportation method of the intermediate sealing door panel 38 and the final sealing door panel 39 is similar to steps 2 to 4 of the initial sealing door panel 37, and steps 2 to 5 are repeated.

[0123] 7. Once all the door panels have been transported and installed, the transport trolley 6 will automatically return to the canopy 4 and park there.

[0124] 8. After all the sealing door panels are installed in place, the operator inserts the movable latch into the locking seat of the sealing door panel to lock the sealing door panel tightly to the well frame 7 to ensure a sealing effect.

[0125] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
