Description

Technical Field

[0001] This invention relates to the field of flood control and disaster relief technology, specifically to a modular tandem drainage vehicle for tunnels. Background Technology

[0002] Urban tunnels, long highway tunnels, and underground culverts face severe challenges in flood control and drainage. The narrow and long interior spaces of tunnels, with significant longitudinal slope differences, mean that in the event of severe flooding, the water level can rise rapidly, easily causing power outages in the internal power supply system, which in turn leads to interruptions in fresh air supply and the accumulation of toxic and harmful gases, seriously threatening the lives of rescue personnel and trapped people.

[0003] Currently, tunnel drainage mainly employs two methods: First, large drainage rescue vehicles (such as "dragon suction trucks") are used. These devices have high lift and large flow rates, but due to limitations in their overall structure and suction method, they can only operate in open areas such as tunnel entrances or under overpasses, unable to penetrate deep into the tunnel. For tunnels exceeding several hundred meters in length, drainage only at the tunnel entrance is insufficient to solve the problem of deep-seated water accumulation. Second, small rescue pumps are manually laid. Rescue personnel need to wade into the tunnel, laying cables and hoses step by step to advance the pumps inward. This method is not only inefficient and time-consuming, but also poses significant safety risks to workers in oxygen-deficient and toxic environments. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a modular, tandem drainage vehicle for tunnels, which effectively solves the problems of low efficiency and high risk associated with manually laying small emergency pumps in existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a modular tandem drainage vehicle for tunnels, comprising: Engineering vehicles; The deformable and retractable mechanism installed on the engineering vehicle retracts to the upper part of the chassis of the engineering vehicle in the transport state, and unfolds outward and downward in the working state to deliver the submersible pump to the area above the water accumulation area. A pump delivery mechanism connected to the deformation and retraction mechanism drives the submersible pump to move in the horizontal and vertical directions; In addition, the generator set, drainage pipeline and fresh air exhaust system are installed on the engineering vehicle.

[0006] Furthermore, the deformation and retraction mechanism includes a tilting arm and a tilting motor; one end of the tilting arm is hinged to the engineering vehicle, the tilting motor is connected to the tilting arm, and the tilting motor drives the tilting arm to rotate around the hinge point.

[0007] Furthermore, the pump delivery mechanism includes a lifting beam, a pump delivery frame, a guide roller, and a pump delivery motor; the lifting beam is fixed to the other end of the tilting arm; the pump delivery frame is slidably connected to the lifting beam; the guide roller is disposed on the pump delivery frame; the pump delivery motor is drivenly connected to the pump delivery frame; and the submersible pump is mounted on the pump delivery frame.

[0008] Furthermore, the exhaust port of the generator set is connected to an exhaust pipe; the engineering vehicle is also equipped with a heat dissipation window corresponding to the generator set.

[0009] Furthermore, the drainage pipeline includes an external pump connection pipe, a suction elbow, and a straight connecting rigid pipe; one end of the straight connecting rigid pipe is connected to the outlet of the submersible pump, and the other end of the straight connecting rigid pipe is connected to the suction elbow or to the external pump connection pipe.

[0010] Furthermore, the straight-connected rigid pipe is provided with support wheels and a rack; the engineering vehicle is provided with a pipe-lifting frame and lifting wheels, and the lifting wheels are in rolling contact with the straight-connected rigid pipe.

[0011] Furthermore, the fresh air and exhaust system includes a fresh air fan and an exhaust fan; the outlet of the fresh air fan is connected to a fresh air duct, and a fresh air inlet is provided at the end of the fresh air duct; the inlet of the exhaust fan is connected to an exhaust duct, and multiple exhaust manifolds are connected to the exhaust duct, and the exhaust outlet of the exhaust duct is located at the heat dissipation window.

[0012] Furthermore, the exhaust duct is mounted on the engineering vehicle via a tilting bracket, and the tilting bracket is connected to an exhaust bracket motor.

[0013] Furthermore, when the drainage truck is used as a lead vehicle or operates independently, the direct-connect rigid pipe is connected to the suction elbow; when the drainage truck is used as a relay vehicle, the direct-connect rigid pipe is connected to the external relay pipe of the pump.

[0014] Furthermore, it also includes a water hose, through which the external pump connection pipe is connected to a direct-connect rigid pipe of an adjacent drainage vehicle.

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art: This invention utilizes a pump delivery mechanism comprised of a tilting arm, a tilting motor, a lifting beam, a pump delivery frame, and the pump delivery motor to achieve the overall tilting and deployment of a submersible pump and related pipelines. In transport mode, the tilting arm tilts upwards, retracting the pump delivery frame and submersible pump to the roof of the vehicle, reducing the overall vehicle height and facilitating rapid maneuverability. In operation mode, the tilting arm tilts outwards and downwards, delivering the submersible pump above the flooded area. Combined with the sliding of the pump delivery frame, the lowering position of the submersible pump can be precisely adjusted. This deformable storage design significantly reduces on-site deployment time, allowing for operation by a single person without the need for external hoisting equipment.

[0016] Multiple drainage vehicles can be quickly connected in series via external pump extension pipes, direct-connect rigid pipes, and hoses. The lead vehicle sucks up water, and the relay vehicles lift it step by step, achieving continuous pumping of water accumulated in long tunnels. The drainage capacity increases linearly with the number of vehicles. At the same time, each vehicle is independently equipped with a fresh air fan, fresh air rigid pipe, and exhaust fan and exhaust pipe. It can provide fresh air to the depths of the tunnel and extract harmful gases after a power outage, ensuring the safety of rescue personnel and overcoming the shortcomings of traditional methods that cannot penetrate deep into the tunnel.

Detailed Implementation

[0020] 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] Example 1:

[0023] A modular, tandem drainage vehicle for tunnels is primarily used for flood control and emergency drainage in urban tunnels, long highway tunnels, and underground culverts. Multiple drainage vehicles can operate independently or be used in series to adapt to flood scenarios of varying lengths and depths. Each vehicle is deformable and retractable for easy transport and rapid deployment.

[0024] like Figure 1 and Figure 2 As shown, the modular tandem drainage vehicle for tunnels in this embodiment includes an engineering vehicle 101. The engineering vehicle 101 is a heavy-duty truck chassis, has self-propelled capability, and can quickly reach the disaster relief site.

[0025] like Figure 1 As shown, a tilting arm 102 is installed on the engineering vehicle 101, with one end of the tilting arm 102 hinged to the frame of the engineering vehicle 101. A tilting motor 103 is connected to the tilting arm 102, driving the tilting arm 102 to rotate around the hinge point. Specifically, the tilting motor 103 is a hydraulic motor or an electric motor, connected to the hinge shaft of the tilting arm 102 via a reduction mechanism. When the tilting motor 103 rotates forward, the tilting arm 102 tilts upward, causing the lifting beam 104, pump delivery frame 105, and submersible pump 308 on it to retract towards the roof of the vehicle. Figure 2 As shown; when the tilting motor 103 rotates in the opposite direction, the tilting arm 102 tilts outward and downward, sending the upper part to the side or front of the vehicle body.

[0026] The other end of the tilting arm 102 is fixed to a lifting beam 104. A slide rail (not shown in the diagram) is provided on the lifting beam 104, and the pump delivery frame 105 is slidably connected to the lifting beam 104 via a slider. A guide roller 106 is provided on the pump delivery frame 105; the guide roller 106 consists of multiple parallel rollers used to guide the lifting wire rope or chain of the submersible pump 308. A pump delivery motor 107 is drively connected to the pump delivery frame 105, and the pump delivery motor 107 drives the pump delivery frame 105 to slide back and forth along the lifting beam 104 via a lead screw or chain.

[0027] The movement process is as follows: After the tilting arm 102 tilts outward into position, the pump motor 107 starts, driving the pump frame 105 to extend forward. Figure 1 As shown, the pump delivery frame 105 extends from the side of the vehicle body above the water accumulation area, and its extension length can be adjusted according to site requirements. Subsequently, the winch mechanism (not shown in the diagram) mounted on the pump delivery frame 105 releases the steel wire rope, and the submersible pump 308 is lowered vertically into the water along the guide rod 106. In reverse operation, the winch mechanism lifts the submersible pump 308, the pump delivery motor 107 drives the pump delivery frame 105 to retract backward, and the tilting motor 103 drives the tilting arm 102 to tilt upward and retract to the roof of the vehicle, completing the storage.

[0028] The resulting effect: Through the combined motion of the rotating boom and the linear sliding of the pump delivery frame, the submersible pump can be quickly switched from the transport position to the working position. The entire process requires no external crane and can be completed remotely by a single person, reducing deployment time from tens of minutes to less than 5 minutes. When folded, the overall vehicle height is less than 4 meters, meeting the height restrictions for highway transportation.

[0029] like Figure 1 As shown, the engineering vehicle 101 is also equipped with a generator set 201 to provide power for the vehicle's submersible pump, fan, tilting motor, and pump delivery motor. The exhaust port of the generator set 201 is connected to an exhaust pipe 202, which extends upwards to the roof of the vehicle to discharge exhaust gases outside, preventing them from accumulating inside the tunnel. The engineering vehicle 101 is also equipped with a cooling vent 203, located at the cooling air duct outlet of the generator set 201, used to exhaust the cooling air from the generator set.

[0030] like Figure 1 and Figure 3 As shown, the engineering vehicle 101 is equipped with a pump external connection pipe 301, a suction elbow 302, and a straight connection rigid pipe 303. One end of the straight connection rigid pipe 303 is connected to the outlet of the submersible pump 308 via a flange or quick coupling. The other end of the straight connection rigid pipe 303 can be selectively connected to the suction elbow 302 or the pump external connection pipe 301.

[0031] The 303 direct-connect rigid pipe has a multi-section expansion sleeve structure, such as... Figure 1 As shown, a support wheel 304 and a rack 305 are provided on the pipe-laying frame 306. The engineering vehicle 101 is equipped with a pipe-laying frame 306 and lifting wheels 307. The pipe-laying frame 306 is fixed to the vehicle body, and the lifting wheels 307 are installed at the lower end of the pipe-laying frame 306, making rolling contact with the outer wall of the direct-connected rigid pipe 303. When the direct-connected rigid pipe 303 extends or retracts, the lifting wheels 307 roll along the pipe wall, providing support and guidance. The rack 305 is fixed to the lower side of the direct-connected rigid pipe 303 and meshes with a drive gear (not shown) provided on the vehicle body. The drive gear is driven by a telescopic motor (not shown), which drives the rack 305 to move, thereby causing the direct-connected rigid pipe 303 to extend and retract.

[0032] The operation process is as follows: When it is necessary to increase the pumping distance, the telescopic motor starts, drives the gear to rotate, and moves the rack 305 forward. The direct-connecting rigid pipe 303 extends forward under the support of the hanging wheel 307, with a maximum extension length of 6-8 meters. When it is necessary to retract, the telescopic motor reverses, and the direct-connecting rigid pipe 303 retracts backward.

[0033] The resulting effect: Through the rack and pinion telescopic mechanism, the automatic extension and retraction of the direct-connected rigid pipe is realized, enabling the submersible pump to reach a position further away from the vehicle body, adapting to water accumulation areas of different widths. At the same time, the length of the vehicle is reduced after being stored, making it easier to drive.

[0034] like Figure 1 As shown, the engineering vehicle 101 is equipped with a fresh air fan 401, the air outlet of which is connected to a fresh air duct 402. A fresh air inlet 403 is located at the end of the fresh air duct 402. The fresh air duct 402 is a retractable or connectable pipe that can extend forward along with the direct-connection duct 303. The fresh air fan 401 draws in fresh outside air and delivers it through the fresh air duct 402 to the working area deep inside the tunnel, providing breathing air for the rescue personnel. The effect: This solves the problem of interrupted fresh air supply after a power outage in the tunnel, ensuring the safety of the workers.

[0035] like Figure 1 and Figure 3 As shown, the engineering vehicle 101 is also equipped with an exhaust fan 501. The air inlet of the exhaust fan 501 is connected to an exhaust duct 502, and multiple exhaust manifolds 503 are connected to the exhaust duct 502. The exhaust outlet of the exhaust duct is located at the heat dissipation window. One exhaust manifold 503 is aligned with the heat dissipation window 203 of the generator set 201 to remove the hot air generated by the generator set; the remaining exhaust manifolds 503 are used to extract harmful gases and humid air from the tunnel.

[0036] The exhaust duct 502 is mounted on the engineering vehicle 101 via a tilting bracket 505. One end of the tilting bracket 505 is hinged to the vehicle body, and the other end is fixedly connected to the exhaust duct 502. An exhaust bracket motor 504 is connected to the tilting bracket 505. The output shaft of the exhaust bracket motor 504 is connected to the hinge shaft of the tilting bracket 505 via a reduction mechanism.

[0037] The movement process is as follows: In the transport state, such as... Figure 2 As shown, the exhaust bracket motor 504 drives the tilting bracket 505 to rotate upwards, lifting the exhaust duct 502 to the roof and retracting it, thus reducing the vehicle's width. In operation, as shown... Figure 1 As shown, the exhaust bracket motor 504 reverses, and the flip bracket 505 rotates downward, lowering the exhaust pipe 502 to the side below the vehicle body. At this time, a corrugated hose can be easily connected to the outlet of the exhaust pipe 502 to lead the exhaust gas to the outside of the tunnel.

[0038] The resulting effect: The flip-top design allows the exhaust duct to be compactly stored during transportation and can be quickly unfolded and connected to the external exhaust hose during operation, avoiding damage to the duct during transportation and improving on-site connection efficiency.

[0039] Example 2:

[0040] When used for drainage of short-distance culverts or underpasses, only one drainage vehicle is used. After the vehicle is parked at the edge of the flooded area, the tilting motor 103 is first started, and the tilting arm 102 tilts outward and downward 90 degrees; then the pump motor 107 is started, and the pump frame 105 extends forward to above the floodwater; the winch mechanism lowers the submersible pump 308 into the water. At the same time, the telescopic motor drives the direct-connection rigid pipe 303 to extend forward to an appropriate length and connects the suction elbow 302 to the front end of the direct-connection rigid pipe 303. The exhaust bracket motor 504 drives the tilting bracket 505 to tilt downward and connect the corrugated hose. The generator set 201, submersible pump 308, fresh air fan 401, and exhaust fan 501 are started. The floodwater is discharged to a distant location through the suction elbow 302, direct-connection rigid pipe 303, and submersible pump 308. As the water level drops, the vehicle can move forward and repeat the above actions. The effect is: single-vehicle operation is flexible and fast, suitable for shallow floodwater and short-distance scenarios.

[0041] When used for drainage in long tunnels, multiple drainage vehicles are connected in series. The first vehicle is arranged in an independent operation mode, but its direct-connection rigid pipe 303 is not connected to the suction elbow 302 at the front end. Instead, it is connected to the external connection pipe 301 of the pump of the relay vehicle behind it through a large-diameter water hose. The relay vehicle is as follows: Figure 3 The suction elbow 302 is removed, and its front end of the direct connection rigid pipe 303 is directly connected to its own external pump connection pipe 301. The external pump connection pipe 301 is then connected to the end of the direct connection rigid pipe 303 of the preceding vehicle via a water hose. In this way, the submersible pumps 308 of multiple vehicles are connected in series. The fresh air rigid pipe 402 and exhaust air pipe 502 of the relay vehicle are also connected to the preceding vehicle via flexible hoses, forming a continuous fresh air and exhaust air channel.

[0042] During operation, vehicles start simultaneously. The submersible pump on the lead vehicle pumps the accumulated water into a water pit at the location of the second vehicle; the submersible pump on the second vehicle pumps the water from that pit to the location of the third vehicle, and so on, until finally the last vehicle drains the water out of the tunnel. Each vehicle has independent power supply and control, and can move inward synchronously as the water level drops. The fresh air system delivers fresh air forward, while the exhaust system extracts exhaust gas backward.

[0043] The resulting effects: With multiple vehicles connected in series, the drainage capacity increases linearly with the number of vehicles. Theoretically, connecting N vehicles in series can increase the drainage height N times, capable of handling drops of several meters or even tens of meters within the tunnel. Simultaneously, the submersible pumps at each relay point always operate at a low suction lift, preventing damage from cavitation caused by excessively high suction lifts on a single large pump. The relay of fresh and exhaust air ensures air circulation throughout the tunnel, allowing rescue operations to continue deeper into the tunnel.

[0044] like Figure 2 As shown, in the transport state, movable parts are folded into the roof or sides, resulting in a compact overall shape and good maneuverability. For example... Figure 1 and Figure 3 As shown, in operation, each mechanism unfolds sequentially with smooth and orderly movements, and the entire deployment can be completed remotely by a single person. Compared with the traditional manual pump deployment method, the deployment time of this invention is reduced by more than 80%, the drainage efficiency is increased several times, and a safe and reliable fresh air environment is provided for the operators.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
