[0002] During tunnel construction, especially when using a tunnel boring machine (TBM) for tunnel excavation, the generation of large amounts of dust is a common and serious problem. Dust not only affects the health of construction workers and increases safety risks in the construction environment, but also causes wear and tear on construction equipment and reduces construction efficiency. Traditional dry dust removal methods mainly use equipment such as gravity settling chambers, cyclone dust collectors or bag dust collectors for dust removal. These devices often need to be fixed and are not suitable for excavation construction sites.

[0003] Wet dust removal devices usually capture dust particles in the air by spraying water mist. Such devices can effectively reduce the dust concentration in the air and improve the construction environment.

DETAILED DESCRIPTION

[0019] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0020] like Figure 1As shown, a TBM tunnel construction integrated wet dust removal device includes a vehicle body 1 and a rotary sprayer 2 on the top thereof, a moving part 3 capable of driving the vehicle body 1 to move is provided at the bottom thereof, the vehicle body 1 is a hollow compartment, the inner cavity of the vehicle body 1 is divided into a first space 5 and a second space 6 by a partition 4, one side of the upper part of the vehicle body 1 is the first space 5 capable of accommodating an energy storage device 7, and the other side of the upper part of the vehicle body 1 and the lower part are the second space 6 capable of accommodating a filter assembly and sewage; a suction device is provided at the front side of the vehicle body 1 for sucking the sewage in the invert and discharging it into the second space 6; the rotary sprayer 2 can extract the upper clear liquid of the sewage and spray water mist around; the moving part 3, the rotary sprayer 2, and the suction device are all connected to a controller and an energy storage device 7. When the vehicle body moves in the tunnel, the suction device is used to suck the sewage in the invert, and the upper clear liquid of the sewage after passing through the filter assembly can enter the rotary sprayer, and then spray water mist into the tunnel space, so as to achieve the purpose of dust reduction during construction.

[0021] In a specific embodiment of the present invention, Figure 1 , 2 As shown, the rotary sprayer 2 includes a rotating component 8, a rotating platform 9 and a plurality of spray pipes 10, wherein the plurality of spray pipes 10 are radially arranged around the rotating platform 9, and a universal nozzle 11 is arranged at the end of the spray pipe 10; the bottom of the rotating platform 9 is connected to a water delivery pipe 40 in the middle of the vehicle body 1, and the water delivery pipe 40 extracts the upper clear liquid of the sewage through a pump 12, and the rotating platform 9 is driven to rotate by the rotating component 8. Among them, the rotating component can adopt a motor and a gear transmission mechanism, and a sleeve with a slewing bearing is set on the outside of the water delivery pipe, and the rotating platform is fixed to the top of the sleeve, and the motor drives the slewing bearing meshing with the gear to rotate, thereby driving the sleeve and the rotating platform to rotate.

[0022] To further optimize the above scheme, a water purification filter 13 is provided inside the rotating platform 9, and the water inlet of the water purification filter 13 is connected to the water supply pipeline 40 through a rotating joint and a water outlet of the water purification filter 13 is connected to multiple spray pipes 10. The water extracted by the water purification filter is purified, and then flows to the universal nozzle through the spray pipe for atomization and high-speed spraying; the rotating platform rotates under the drive of the rotating part, so that the interior of the tunnel space can be filled with uniform and delicate water mist to achieve the purpose of dust reduction. Among them, the filter membrane 47 of the water purification filter can be disassembled and replaced, and a removable cover is provided on the top of the rotating platform for replacing the filter membrane of the water purification filter. At the same time, the filter membrane can be made of stainless steel filter, PP cotton, activated carbon, etc., which can be placed in the storage room 46 in the first space 5, and the filter membrane and the energy storage device are separated by a partition.

[0023] As a preferred structure, Figure 3As shown, the universal nozzle 11 includes a housing 14 and a plurality of nozzles 15 on its surface. The housing 14 is composed of two polygonal pyramids, the large ends of the two polygonal pyramids are connected, each inclined surface of the two polygonal pyramids is provided with a nozzle 15, and the middle of the nozzle 15 is provided with a spray hole 16. The universal nozzle with this structure can spray fine water mist in different directions, and the water mist can fill the tunnel as the rotating platform rotates.

[0024] Further optimize the above scheme, such as Figure 1 As shown, the upper and lower sides of the rotating platform 9 are respectively provided with circular cathode plates 17, and the universal nozzle 11 is arranged on the inner side of the edge of the cathode plate 17; the anode plate 18 is inclinedly arranged on the rear side of the vehicle body 1, and the bottom of the anode plate 18 is provided with a dust storage tank 19 filled with water; the anode plate 18 and the cathode plate 17 are both connected to the energy storage device 7. When it is necessary to clean the dust efficiently, the switch of the cathode plate can be turned on. The cathode plate carries negative electricity. When the water mist is sprayed evenly, the water mist can be given a negative charge, so that the water mist has a higher dust attraction, achieving a more efficient and comprehensive dust cleaning effect. At the same time, as the vehicle body moves, the water mist carrying negative charges above attracts the surrounding dust to form dust particles, which fall downward under the action of gravity and are attracted to the anode plate below, reducing the impact of dust on the surrounding environment. When there is enough dust on the anode plate, it will slide into the dust storage tank below. The clean water inside the dust storage tank can collect dust and reduce the flying of dust.

[0025] In a specific embodiment of the present invention, Figure 1 As shown, the suction device includes a suction pipe 20, a pump body 21 and a suction head 22. The pump body 21 is controlled by a controller and connected to the suction pipe 20. A U-shaped elbow 23 is provided at the top of the suction pipe 20. The outlet end of the U-shaped elbow 23 is arranged above the opening of the second space 6 at the top of the vehicle body 1. The suction head 22 is arranged at the bottom of the suction pipe 20. The upper inner cavity of the suction head 22 is a funnel-shaped one with a small top and a large bottom, and its bottom shape is square. The middle part of the suction head 22 is a honeycomb structure. The square suction head with a honeycomb structure is more suitable for the internal structure of the inverted arch. The use of the honeycomb structure can generate greater suction locally and avoid sucking larger debris into the suction pipe.

[0026] When designing specifically, Figure 1 , 4As shown, the suction tube 20 is connected to a lifting mechanism 24, which is used to drive the suction tube 20 to move up and down; the lifting mechanism 24 includes a worm wheel 25 and a worm 26 meshing therewith, the outer wall of the suction tube 20 is provided with a tooth shape meshing with the worm wheel 25, and the end of the worm 26 is provided with a hand crank 27; the outside of the suction tube 20 is provided with a sleeve 28, and the outside of the worm wheel 25 and the worm 26 is provided with a shell 29, the shell 29 is fixedly connected to the sleeve 28, and the force-applying part of the hand crank 27 extends to the outside of the shell 29. The worm is driven to rotate by turning the hand crank, and the worm drives the worm wheel to rotate, thereby driving the suction tube to move up and down. Of course, the worm wheel can also be driven by a micro motor, and the start and stop of the micro motor can be controlled by a controller.

[0027] To further optimize the above solution, a steering mechanism is provided between the suction tube 20 and the suction head 22. Figure 5 As shown, the steering mechanism includes a driving component 30, a slewing bearing 31 and a connecting pipe 32. The driving component 30 and the slewing bearing 31 are both arranged at the bottom of the sleeve 28. The output end of the driving component 30 is provided with a driving gear 33 that can mesh with the slewing bearing 31. The driving component 30 is controlled by a controller. The connecting pipe 32 is L-shaped. The horizontal end of the connecting pipe 32 is connected to the suction head 22 through a downwardly bent elbow. The slewing bearing 31 is sleeved on the outer wall of the vertical part of the connecting pipe 32. The upper end of the connecting pipe 32 is connected to the lower end of the suction pipe 20 through a rotating joint 34. The above-mentioned steering mechanism can drive the suction head to rotate within a certain range, further expanding the scope of cleaning sewage. In specific production, the junction of the elbow and the suction head 22 is connected by a hose. The outer part of the hose is covered with a spring 50. One end of the spring 50 is connected to the elbow, and the other end can be pressed against the outer table of the suction head 22. The suction head can be pressed against the bottom surface of the invert by the spring, so that it can contact the mud as much as possible; at the same time, it can also provide a buffer force for the suction head to prevent the suction head from hitting hard objects and being damaged.

[0028] In a specific embodiment of the present invention, Figure 1As shown, the filter assembly includes two horizontally arranged screen partitions with screen holes, and a discharge door corresponding to the upper and lower inner cavities of the screen partition is provided on the side wall of the vehicle body 1; the two screen partitions are respectively a fine-pore screen plate 35 and a coarse-pore screen plate 36 arranged at intervals from bottom to top, the screen hole size of the fine-pore screen plate 35 is smaller than the screen hole size of the coarse-pore screen plate 36, the inner side of the coarse-pore screen plate 36 is separated from the first space 5 by a partition 4, and a buffer pad 37 is laid on the bottom partition of the first space 5, and the fine-pore screen plate 35 matches the bottom plate area of ​​the vehicle body 1 and is arranged below the first space 5 and the coarse-pore screen plate 36; The unloading door is composed of a lower door 38, a middle door 39 and an upper door 48 arranged on the front side wall of the vehicle body 1 from bottom to top.

The second space 6 is divided into three compartments by using a coarse-pore sieve plate 36 and a fine-pore sieve plate 35. Muddy sewage with different particle sizes and roughness will flow into different compartments to achieve graded filtration of sewage. The filtered debris can be cleaned through the lower door 38, the middle door 39 and the upper door 48. The lower end of the water supply pipe 40 extends to below the liquid surface of the lowest compartment to facilitate the extraction of the upper clear liquid.

[0029] like Figure 6 , 7 As shown, the locking mechanism includes a fixing block 51, a locking rod 52, a locking spring 53 and a limiting ring 54, wherein the limiting ring 54 is arranged on the outer wall of the lower door 38, and a space for the locking rod 52 to move up and down is provided between the limiting ring 54 and the outer wall of the lower door 38, the upper end of the locking spring 53 is connected to the cylindrical locking rod 52, and the lower end is connected to the fixing plate 55 on the outer wall of the lower door 38; the fixing block 51 is arranged on the outer wall of the vehicle body 1, and the side of the fixing block 51 is provided with a locking hole 510 and an open slideway 511 on the outside, the locking hole 510 can accommodate the end of the locking rod 52, the slideway 511 is connected to the bottom of the locking hole 510, and the locking rod 52 can enter the locking hole 510 along the slideway 511; the locking mechanism on both sides of the middle door 39 and the upper door 48 has the same structure as the locking mechanism on both sides of the lower door 38. During operation, the locking mechanisms on both sides of the lower door, the middle door and the upper door are in a locked state. When slag discharge is required, the locking rod 52 is pressed downward to disengage it from the locking hole 510 and slide outward along the slideway 511, and then reset in the limit ring 54 under the action of the locking spring 53; when dust removal is needed again, the lower door, the middle door and the upper door are closed, and the locking mechanism can be locked by reverse operation.

[0030] During specific design, drainage holes 45 are designed at the bottom of the lowest cabin, and water can be drained when not in use. Simultaneously, hydraulic push plates are provided in the three cabins of the second space 6, and the slag and gravel at the bottom of the three cabins are scraped and discharged when not in use.

[0031] In a specific embodiment of the present invention, Figure 1 As shown, the walking part 3 includes four wheels, a plurality of wire spokes 41 are provided inside the wheels, an arc-shaped permanent magnet 42 is provided on the upper outer side of the wheels, the wire spokes 41 are connected to the motor 44 at the bottom of the vehicle body 1 through a transmission line 43, and the motor 44 is connected to the energy storage device 7 through a cable. Among them, the motor includes a stator (with windings) and a rotor (with permanent magnets), and the wheel has a built-in electronic control system that can switch between motors and motor modes when necessary (this is a prior art, and its detailed structure is not repeated here). When the vehicle body needs to accelerate, an external power supply provides electrical energy to the motor, and the current flows through the winding to generate a magnetic field that interacts with the permanent magnet, driving the wheel to accelerate. When the vehicle body passes through a tunnel with a slope downward or needs to slow down, the motor will switch to a power generation mode, and the kinetic energy of the wheel will be converted into electrical energy. The specific working process is as follows: When the wheel rotates, the wire spokes cut the magnetic flux lines and generate current. When braking is needed, the reaction force of the electric motor is used to produce a braking effect and slow down the wheel. When the wheel slows down, the induced current can also flow back to the energy storage device through the power recovery device for future acceleration and energy recovery. Because the vehicle body runs very slowly, it can also be equipped with a traditional friction brake system to supplement the wheel with auxiliary braking. This technology is used in existing new energy electric vehicles.

[0032] To further optimize the above solution, an intelligent navigation module can be installed in the controller to facilitate remote control. A touch screen (not shown) is provided on the side of the vehicle body 1, which is connected to the controller and is more convenient to operate on the touch screen. At the same time, an audible and visual alarm and a camera can be installed on the outside of the vehicle body to warn surrounding staff and monitor the surrounding environment.

[0033] In summary, the present invention has the following advantages compared with the prior art: 1. By integrating anode plates and cathode plates in the wet dust removal device and using the electric field enhancement system to enable the sprayed water mist to carry electric charge, the adsorption capacity and dust removal efficiency of dust particles are significantly improved, and the dust removal effect is effectively improved, especially when dealing with fine dust particles.

[0034] 2. The mobile vehicle body can be flexibly moved in the tunnel to ensure comprehensive and uniform coverage of the construction area and enhance the dust removal effect. The present invention can adapt to different construction environments and tunnel lengths, and improves the flexibility and adaptability of operation.

[0035] 3. Energy recovery is achieved through wheel deceleration, and the kinetic energy during the operation of the equipment is converted into electrical energy, which is stored in the energy storage device to power the motor, anode plate, cathode plate or other components. This technical improvement not only reduces energy consumption, but also improves the energy utilization efficiency of the equipment.

[0036] 4. Optimized dust removal system design: The anode plate, cathode plate and rotary sprayer are integrated into the mobile vehicle body, making the overall structure more compact, easier to operate and maintain, and reducing the complexity and operating costs of the equipment.

[0037] 5. The present invention improves the intelligent operation and safety of the car and reduces the manual burden by equipping it with an intelligent navigation module, a touch screen, an audible and visual alarm and a camera.

[0038] The present invention can effectively capture dust during tunnel construction, significantly improve the health of construction workers, reduce respiratory diseases and health risks, while improving the safety of the construction environment, reducing the risk of accidents and equipment wear caused by dust, thereby improving construction efficiency and economic benefits; at the same time, it can also reduce secondary pollution caused by sewage discharge, optimize the working environment, and improve the comfort and work efficiency of construction workers, reflecting significant advantages in construction safety, health protection and environmental sustainable development.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
