Description
Technical Field
[0001] This invention relates to the field of dust suppression technology in tunnel construction, specifically to an energy-saving and environmentally friendly intelligent dust suppression device for tunnel construction. Background Technology
[0002] Currently, most tunnels in my country are constructed using drill-and-blast and mechanical tunneling methods, which generate a large amount of dust during construction. Tunnel construction differs from other above-ground construction because it takes place in a relatively enclosed space, and dust generated during construction cannot be effectively controlled through conventional measures.
[0003] If the large amount of dust generated after blasting at the working face is not cleaned up in time, it will first affect the health of the workers, and secondly, the dust in the air will affect visibility and pose certain safety hazards to the construction operation. Summary of the Invention
[0004] The purpose of this invention is to provide an energy-saving and environmentally friendly intelligent dust suppression device for tunnel construction, which can quickly and effectively purify the dust generated by blasting during tunnel construction.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] An energy-saving and environmentally friendly intelligent dust suppression device for tunnel construction includes a vehicle-mounted mechanism, an isolation curtain mechanism installed on the vehicle-mounted mechanism, and a dust filtration mechanism installed on the vehicle-mounted mechanism.
[0007] The vehicle-mounted mechanism includes a vehicle chassis, with four sets of drive wheels at the bottom of the vehicle chassis that can be driven and steered independently, and an overall support plate fixedly installed on the top of the vehicle chassis;
[0008] The drive wheel assembly in the vehicle-mounted mechanism is controlled and driven by remote control.
[0009] The isolation curtain mechanism includes a curtain support housing fixed to the overall support plate and near the right end, multiple curtain support rods folded and fixed to the curtain support housing, and an isolation curtain fixed to the curtain support rods;
[0010] The curtain support housing is a hollow shell with an arc-shaped upper side. Multiple first fixed hinges are fixedly installed on the upper side of the curtain support housing. One end of the curtain support rod is fixedly connected to the pivot of the first fixed hinge. The pivot of the first fixed hinge extends along the tangent direction on the upper side of the curtain support housing, and the axis of the pivot of the first fixed hinge is perpendicular to the axis of the curtain support housing. The pivot of the first fixed hinge is driven to rotate by a motor.
[0011] An isolation curtain is fixed between every two adjacent curtain support rods;
[0012] The dust filtration mechanism includes a suction pipe fixed on the curtain support rod. The suction pipe has multiple suction holes that communicate with each other on its side wall. A dust collection box and an air extractor are fixed on the top of the overall support plate. The suction pipe is connected to the inside of the dust collection box through a pipe, and the input end of the air extractor is connected to the inside of the dust collection box through a pipe.
[0013] Preferably, the vehicle-mounted mechanism is equipped with an isolation exhaust compensation mechanism, which includes a first telescopic rod fixed to the top of the overall support plate. The first telescopic rod is a multi-stage electrically controlled telescopic rod. The outer rod of the first telescopic rod is connected to the top of the overall support plate through a second fixed hinge. The inner rod end of the first telescopic rod is fixedly provided with a compensation exhaust pipe, which is connected to the output end of the vacuum pump through a pipe.
[0014] Note: During the dust cleanup process after the blast, the exhaust pipe in the isolation exhaust compensation mechanism is used to exhaust air from the working face, causing the dusty air to flow more quickly toward the suction pipe.
[0015] Preferably, a hollow compensating exhaust ring is fixedly provided on the compensating exhaust pipe, the interior of the compensating exhaust ring is connected to the interior of the compensating exhaust pipe, the axis of the compensating exhaust ring is coaxial with the axis of the compensating exhaust pipe, and the compensating exhaust ring has multiple exhaust short pipes connected to its own interior, the axis of the exhaust short pipes being arranged to extend radially along the compensating exhaust ring.
[0016] Explanation: The multiple short exhaust pipes on the compensating exhaust ring exhaust air to the working face, forming an air curtain, which intensifies the flow of dusty air towards the suction pipe, making it easier to quickly collect and clean up the dust generated by the explosion.
[0017] Preferably, the compensating exhaust pipe is connected to the inner end of the first telescopic rod via a third fixed hinge, the support of the third fixed hinge is fixedly connected to the inner end of the first telescopic rod, the compensating exhaust pipe is fixedly connected to the rotating shaft of the third fixed hinge, and the rotating shaft of the third fixed hinge is driven to rotate by a motor.
[0018] Explanation: The motor drives the shaft of the third fixed hinge to rotate, thereby adjusting the orientation of the exhaust pipe and the exhaust airflow direction of multiple exhaust short pipes.
[0019] Preferably, the curtain support rod is connected to the curtain support housing through a curtain drive mechanism. The curtain drive mechanism includes a channel support block fixed inside the curtain support housing. The top of the channel support block has an arc-shaped structure, and the arc at the top of the channel support block is concentric with the arc on the upper side of the curtain support housing. A slide rail channel is formed between the top of the channel support block and the top of the curtain support housing.
[0020] A curtain drive slider is slidably fitted inside the slide rail channel. Racks are fixedly installed at the top and bottom of the slide rail channel. Multiple drive gears are rotatably fitted on the curtain drive slider. The drive gears mesh with the racks and are driven to rotate by a motor.
[0021] The upper side of the curtain support housing has a tilting connecting groove that connects the inside and outside. The support of the first fixed hinge is fixed on the drive slider, and the end of the first fixed hinge connected to the curtain support rod extends out from the tilting connecting groove.
[0022] Note: The relative positions of multiple screen support rods are adjusted through the screen drive mechanism, making it easy to fold and store the multiple screen support rods.
[0023] Preferably, the drive gear is driven to rotate by a motor through a worm gear transmission.
[0024] Explanation: The drive gear rotates through a worm gear transmission, which utilizes the self-locking characteristic of the worm gear transmission to fix the position of the curtain drive slider relatively within the slide rail channel.
[0025] Preferably, a spray interception mechanism is provided between the suction pipe and the dust collection box. The spray interception mechanism includes a dust interception pipe. A reducing pipe is fixedly provided at one end of the dust interception pipe. The diameter of the reducing pipe gradually decreases from the end closer to the dust interception pipe to the end farther away from the dust interception pipe. The end of the reducing pipe with a smaller diameter is connected to the suction pipe through a pipe.
[0026] Multiple hollow spray rings are fixed inside the dust interception tube. The axis of the spray rings is coaxial with the axis of the dust interception tube. Multiple atomizing nozzles are provided on the inner side of the spray rings and on the side near the reducing tube.
[0027] Multiple mud discharge pipes connected to the interior of the dust interception pipe are fixedly installed on the lower side of the pipe. The lower ends of the mud discharge pipes are connected to a mud recovery box, which is fixed to the overall support plate.
[0028] Note: The spray interception mechanism can settle the recovered dust, so that most of the dust is stored in the form of mud in the mud recovery box, while the remaining small amount of dust is concentrated in the dust collection box.
[0029] Preferably, the spray ring is connected to the inner wall of the dust interception tube via a spacing adjustment mechanism. The spacing adjustment mechanism includes a spacing adjustment slide rail fixed to the top of the dust interception tube. The spacing adjustment slide rail extends along a direction parallel to the axis of the dust interception tube. Multiple spacing adjustment sliders are slidably fitted on the spacing adjustment slide rail. The spacing adjustment sliders are driven by a motor to move along the spacing adjustment slide rail. The spray ring is fixedly connected to the spacing adjustment slider one-to-one.
[0030] Explanation: The spacing adjustment mechanism uses a motor to drive the spacing adjustment slider to move along the spacing adjustment slide rail, thereby adjusting the relative position of the spray ring inside the dust interception tube. Depending on the density of the dust, the water mist sprayed from the dust interception tube has a better dust suppression effect.
[0031] Preferably, an auxiliary cleaning pipe is fixedly installed on each of the front and rear sides inside the dust interception pipe, and the side wall of the auxiliary cleaning pipe has multiple drainage holes that communicate with each other inside and outside.
[0032] Note: The water flow from the drain hole of the auxiliary cleaning pipe can clean the inner wall of the dust interception pipe, preventing excessive dust and sludge from adsorbing onto the inner wall of the dust interception pipe.
[0033] Preferably, the overall support plate is provided with an isolation and pressure relief mechanism, which includes two second telescopic rods fixed to the right end of the overall support plate. The second telescopic rods are multi-stage electrically controlled telescopic rods, which extend in the front-back direction, and the inner rods of the two second telescopic rods face the ends that are far apart from each other.
[0034] A pressure relief curtain is hung on the second telescopic rod, and there is a suspension point between each inner rod of the second telescopic rod and the pressure relief curtain.
[0035] The pressure relief curtain has pressure relief holes, and a pressure relief hole curtain is fixedly installed at the pressure relief hole. Only the upper edge of the pressure relief hole curtain is fixedly connected to the pressure relief curtain at the upper side of the pressure relief hole, and a counterweight rod is fixedly installed at the lower edge of the pressure relief hole curtain.
[0036] Explanation: When blasting occurs at the tunnel face, a curtain wall composed of multiple isolation curtains relatively isolates the blasting area. At the moment of blasting, the air pressure in the relatively isolated area will change and increase rapidly. This may cause high-speed airflow to be generated at the location of the curtain wall composed of multiple isolation curtains due to the rapid increase in air pressure, which in turn will bring up a large amount of dust on the ground. The pressure relief holes in the isolation and pressure relief mechanism are designed to balance the airflow generated by this rapid increase in air pressure and to guide the airflow out of the pressure relief holes in a timely manner. The pressure relief curtain at the pressure relief hole will temporarily seal the pressure relief hole under the gravity of the counterweight rod.
[0037] Compared with the prior art, the beneficial effects of the present invention are:
[0038] 1. The present invention has a reasonable structural design and is easy to operate. The vehicle-mounted design facilitates the movement and relocation of the entire device, and makes it easy for staff to quickly deploy the entire device.
[0039] 2. The invention utilizes an isolation curtain connected by multiple curtain support rods to relatively isolate the blasting area during tunnel excavation, and uses a dust filtration mechanism to quickly clean up the dust generated by blasting, preventing dust from spreading in the air and creating a cleaner working environment for the workers.
[0040] 3. During the blasting process, the air pressure in the isolated area will change and increase rapidly. The isolation and pressure relief mechanism in this invention can basically eliminate the dust generated near the equipment due to the rapid change in air pressure. Attached Figure Description

[0050] Example:
[0051] An energy-saving and environmentally friendly intelligent dust suppression device for tunnel construction, such as... Figure 1 , Figure 3 As shown, it includes a vehicle-mounted mechanism 10, an isolation curtain mechanism 20 disposed on the vehicle-mounted mechanism 10, and a dust filter mechanism 30 disposed on the vehicle-mounted mechanism 10.
[0052] like Figure 1 As shown, the vehicle-mounted mechanism 10 includes a vehicle-mounted chassis 11.

[0056] An isolation curtain 23 is fixed between every two adjacent curtain support rods 22;
[0057] like Figure 5 As shown, the curtain support rod 22 is connected to the curtain support housing 21 through the curtain drive mechanism 24. The curtain drive mechanism 24 includes a channel support block 241 fixed inside the curtain support housing 21. The top of the channel support block 241 is an arc-shaped structure, and the arc at the top of the channel support block 241 is concentrically arranged with the arc on the upper side of the curtain support housing 21. A slide rail channel 240 is formed between the top of the channel support block 241 and the top of the curtain support housing 21.
[0058] A curtain drive slider 242 is slidably fitted inside the slide rail channel 240. Racks 243 are fixedly installed at the top and bottom of the slide rail channel 240.

[0059] The upper side of the curtain support housing 21 has a tilting connecting groove 211 that connects the inside and outside. The support of the first fixed hinge 210 is fixed on the drive slider 242. One end of the first fixed hinge 210 connected to the curtain support rod 22 extends out from the tilting connecting groove 211.
[0060] The drive gear 244 is driven to rotate by a motor through a worm gear transmission.
[0061] like Figure 1 As shown, the dust filtration mechanism 30 includes a suction pipe 31 fixed on the curtain support rod 22. The side wall of the suction pipe 31 has multiple suction holes that communicate with the inside and outside. The top of the overall support plate 12 is fixedly provided with a dust collection box 32 and an air extractor 33. The suction pipe 31 is connected to the inside of the dust collection box 32 through a pipe, and the input end of the air extractor 33 is connected to the inside of the dust collection box 32 through a pipe.
[0062] like Figure 3 As shown, a spray interception mechanism 34 is provided between the suction pipe 31 and the dust collection box 32, such as... Figure 6As shown, the spray interception mechanism 34 includes a dust interception pipe 341. A reducing pipe 342 is fixedly provided at one end of the dust interception pipe 341. The diameter of the reducing pipe 342 gradually decreases from the end near the dust interception pipe 341 to the end far away from the dust interception pipe 341. The end of the reducing pipe 342 with a smaller diameter is connected to the suction pipe 31 through a pipe.
[0063] Multiple hollow spray rings 343 are fixedly installed inside the dust interception tube 341. The axis of the spray rings 343 is coaxial with the axis of the dust interception tube 341. Multiple atomizing nozzles 344 are provided on the inner side of the spray rings 343 and on the side near the reducing tube 342.
[0064] Multiple mud discharge pipes 345 connected to the interior of the dust interception pipe 341 are fixedly installed on the lower side of the dust interception pipe 341. The lower ends of the mud discharge pipes 345 are connected to a mud recovery box 346, which is fixed on the overall support plate 12.

The spacing adjustment mechanism 35 includes a spacing adjustment slide rail 351 fixed to the top of the dust interception tube 341.

The spacing adjustment sliders 352 are driven by a motor to move along the spacing adjustment slide rail 351. The spray ring 343 is fixedly connected to the spacing adjustment sliders 352 one-to-one.
[0066] An auxiliary cleaning pipe 347 is fixedly installed on each of the front and rear sides inside the dust interception pipe 341. The side wall of the auxiliary cleaning pipe 347 has multiple drainage holes that are connected inside and outside.
[0067] like Figure 1 As shown, the vehicle-mounted mechanism 10 is equipped with an isolation exhaust compensation mechanism 40. The isolation exhaust compensation mechanism 40 includes a first telescopic rod 41 fixed to the top of the overall support plate 12. The first telescopic rod 41 is a multi-stage electrically controlled telescopic rod. The outer rod of the first telescopic rod 41 is connected to the top of the overall support plate 12 through a second fixed hinge 410. The inner rod end of the first telescopic rod 41 is fixedly provided with a compensation exhaust pipe 42. The compensation exhaust pipe 42 is connected to the output end of the vacuum pump 33 through a pipe.
[0068] like Figure 7 As shown, a hollow compensating exhaust ring 43 is fixedly provided on the compensating exhaust pipe 42. The interior of the compensating exhaust ring 43 is connected to the interior of the compensating exhaust pipe 42. The axis of the compensating exhaust ring 43 is coaxial with the axis of the compensating exhaust pipe 42. The compensating exhaust ring 43 has multiple exhaust short pipes 431 that are connected to its own interior. The axis of the exhaust short pipes 431 is arranged to extend radially along the compensating exhaust ring 43.
[0069] The compensating exhaust pipe 42 is connected to the inner rod end of the first telescopic rod 41 via a third fixed hinge 420. The support of the third fixed hinge 420 is fixedly connected to the inner rod end of the first telescopic rod 41. The compensating exhaust pipe 42 is fixedly connected to the rotating shaft of the third fixed hinge 420. The rotating shaft of the third fixed hinge 420 is driven to rotate by a motor.
[0070] like Figure 4 As shown, an isolation and pressure relief mechanism 50 is provided on the overall support plate 12. The isolation and pressure relief mechanism 50 includes two second telescopic rods 51 fixed to the right end of the overall support plate 12. The second telescopic rods 51 are multi-stage electrically controlled telescopic rods. The second telescopic rods 51 extend in the front-back direction, and the inner rods of the two second telescopic rods 51 face the ends that are far apart from each other.
[0071] A pressure relief curtain 52 is hung on the second telescopic rod 51, and there is a suspension point between each inner rod of the second telescopic rod 51 and the pressure relief curtain 52.
[0072] The pressure relief curtain 52 has a pressure relief hole 521. A pressure relief hole curtain 522 is fixedly installed on the pressure relief curtain 52 at the pressure relief hole 521. Only the upper edge of the pressure relief hole curtain 522 is fixedly connected to the pressure relief curtain 52 at the upper side of the pressure relief hole 521. A counterweight rod 523 is fixedly installed on the lower edge of the pressure relief hole curtain 522.
[0073] In practical application, the entire device is moved to a position close to the tunnel face along the centerline of the tunnel, with one end of the curtain support housing 21 facing the tunnel entrance. In the initial state, the multiple curtain support rods 22 are in a horizontally extended folded state.
[0074] Before the blasting operation, the first fixed hinge 210 is driven to rotate by a motor. The first fixed hinge 210 drives the curtain support rod 22 to deflect, so that the axis of the curtain support rod 22 extends along the radial direction of the upper side of the curtain support shell 21.
[0075] Then the motor drives the drive gear 244 to rotate through the worm gear transmission. Since the drive gear 244 meshes with the rack 243, it forces the curtain drive slider 242 to move along the slide rail channel 240. The curtain drive sliders 242 move away from each other in the slide rail channel 240.
[0076] The curtain drive slider 242 drives the curtain support rod 22 to move through the first fixed hinge 210, so that multiple curtain support rods 22 move away from each other. Then the isolation curtain 23 connected between the curtain support rods 22 will unfold, forming an isolation curtain wall in the tunnel. A relatively closed space is formed between the isolation curtain wall and the tunnel face.
[0077] The inner rod of the second telescopic rod 51 in the isolation and pressure relief mechanism 50 extends, causing the pressure relief curtain 52 to unfold, thereby improving the isolation and sealing performance of the isolation curtain wall.
[0078] During the blasting, a large amount of dust will be generated, and the air pressure in the relatively enclosed space between the isolation curtain wall and the tunnel face will change rapidly and increase. The airflow generated by the increased air pressure will be discharged from the pressure relief hole 521.
[0079] After the blast, the air extraction machine 33 is started. The air extraction machine 33 removes the air from the dust collection box 32, creating a negative pressure inside the dust collection box 32. The dust collection box 32 is connected to the suction pipe 31 through a pipe. The dusty air in the tunnel is sucked into the suction pipe 31 under the action of negative pressure. The dust that enters the suction pipe 31 is then collected into the dust collection box 32 through the pipe.
[0080] As the dust entering the suction pipe 31 is collected into the dust collection box 32 through the pipe, it is first processed by the spray interception mechanism 34. The dust entering the suction pipe 31 first enters the reducing pipe 342. As the air mixed with dust flows from the reducing pipe 342 toward the dust interception pipe 341, the air velocity will decrease due to the increase in the cross-section of the reducing pipe 342, which is conducive to the dust settling by water mist.
[0081] The air mixed with dust then passes through the dust interception pipe 341, and the dust is settled by the water mist sprayed by multiple atomizing nozzles 344 on the spray ring 343. After the dust settles with water, it turns into mud and flows into the mud recovery tank 346 through the mud discharge pipe 345.
[0082] Simultaneously with the start of the vacuum pump 33, the inner rod of the first telescopic rod 41 extends to move the compensating exhaust pipe 42 to the tunnel face. A dust filter is located between the input end of the vacuum pump 33 and the dust collection box 32. Clean air discharged from the output end of the vacuum pump 33 is introduced into the compensating exhaust pipe 42. Air in the compensating exhaust pipe 42 is ejected from the end. Part of the air in the compensating exhaust pipe 42 enters the compensating exhaust ring 43 and is then ejected from multiple exhaust short pipes 431, spraying air at the tunnel face. This forces the air containing a large amount of dust to flow from the tunnel face toward the suction pipe 31, facilitating the rapid collection of air containing a large amount of dust.
