Description

Technical Field

[0001] This application relates to the technical field of tunnel dust suppression, and in particular to an intelligent control robot for rapid ventilation, smoke extraction and dust suppression in long tunnels. Background Technology

[0002] With the rapid development of highway construction in my country, the requirements for highway tunnel engineering construction are becoming increasingly stringent. Along with the deepening of the "people-oriented" concept, the occupational health, safety, and environmental protection awareness of construction units and workers is also constantly being enhanced. Improving the tunnel working environment, reducing safety risks, and strengthening environmental protection have thus become urgent issues facing current tunnel engineering construction.

[0003] During tunnel construction, drilling, blasting, excavation, transportation and other processes inevitably generate dust and harmful gases. These harmful substances are not easily dispersed in the relatively enclosed working environment inside the tunnel and remain suspended at the top of the tunnel. Generally, the dust is sucked out of the tunnel by wind power equipment for discharge. However, when encountering long tunnels, the wind power is often insufficient, resulting in poor dust removal effect. Summary of the Invention

[0004] To improve the dust removal effect in tunnels, this application provides an intelligent robot for rapid ventilation, smoke extraction and dust reduction in long tunnels.

[0005] This application provides an intelligent control robot for rapid ventilation, smoke extraction, and dust suppression in long tunnels, employing the following technical solution:

[0006] A smart robot for rapid ventilation, smoke extraction, and dust suppression in long tunnels includes a body that walks on the tunnel and a dust removal mechanism mounted on the body. The dust removal mechanism includes:

[0007] The suction pipe is installed on the machine body and sucks dust into the machine body as the machine moves;

[0008] A spray assembly, mounted on the machine body, is used to spray dust.

[0009] The discharge assembly, located on the machine body, is used to discharge dust and water into the tunnel.

[0010] By adopting the above technical solution, the machine moves inside the tunnel. As the machine moves, dust suspended at the top of the tunnel enters the machine through the suction pipe. The spray component is activated to spray the dust, which mixes with water and is then discharged through the discharge component. The machine also removes dust close to its location, thus greatly improving the efficiency and effectiveness of dust removal in the tunnel. At the same time, the machine absorbs dust as it moves, eliminating the need for ductwork compared to exhaust through ducts, saving the time spent on duct installation and further improving the efficiency and effectiveness of dust removal in the tunnel.

[0011] Optionally, the discharge assembly is provided in two parts and is used to guide dust and water into drainage ditches located on both sides of the tunnel. A baffle plate is provided inside the machine body and between the two discharge assemblies to block the movement of dust. The spray assembly is used to spray and remove dust located on the side of the baffle plate near the suction pipe and to allow dust and water to flow into the two discharge assemblies for discharge.

[0012] By adopting the above technical solution, dust enters the machine body through the suction pipe and collides with the baffle plate, slowing down its movement speed. At the same time, the spraying component sprays the dust located at the baffle plate, thereby greatly improving the dust removal effect. Dust and water are discharged into the drainage ditches located on both sides of the tunnel through two discharge components, thereby further greatly improving the dust removal efficiency and effect of the tunnel.

[0013] Optionally, the machine body is provided with inclined and arched guide plates and filter plates. The height of the guide plate near the suction pipe is higher than the height of the end near the baffle plate. The filter plate is located between the guide plate and the baffle plate and is at the same height and lowest near the two discharge components. When the spray component is activated, it sprays dust and causes the dust and water to move onto the filter plate under the action of the guide plate and then move to the two discharge components for discharge under the guidance of the filter plate. The filter plate is evenly provided with multiple filter holes for water to pass through. The machine body is also provided with a return component for returning the water passing through the filter holes to the spray component.

[0014] By adopting the above technical solution, the tunnel is relatively long, and the machine body and spraying components are in a moving state, which makes the water required for the spraying components large. Especially in long tunnels, it greatly increases the weight and size of the machine body when moving, and may even lead to the situation that the water is used up after moving into the tunnel, which greatly reduces the dust removal efficiency and effect on the tunnel.

[0015] The spray assembly is used to spray dust. The guide plate directs the water and dust mixture to the filter plate, which then directs the mixture to two drainage assemblies for discharge. Simultaneously, when water moves onto the filter plate, it can flow back to the spray assembly through the filter holes and the return assembly for recycling. When there is less dust in the air, the dust has a smaller obstruction effect on the filter holes, thus increasing the amount of water passing through them. Conversely, when there is more dust, less water passes through the filter holes. This allows the collected water to push the dust into the discharge assembly for discharge, thereby simultaneously improving the dust removal effect and water collection effect, significantly enhancing the dust removal efficiency and effectiveness of the tunnel.

[0016] Optionally, the reflow component includes:

[0017] A return hood is installed on the machine body and is used to catch water passing through the filter holes;

[0018] A return pipe is installed on the return hood and connected to the spray assembly, and is used to return water to the spray assembly.

[0019] By adopting the above technical solution, water flows into the return hood for collection, and then the water in the return hood flows back into the spray assembly through the return pipe for collection.

[0020] Optionally, the spray assembly includes:

[0021] The spray plate is installed on the machine body and has multiple spray holes evenly distributed on its upper and lower surfaces.

[0022] The spray box is installed on the machine body and is filled with spray water;

[0023] A spray pump is installed on the spray box and is equipped with a spray pipe that is connected to the spray plate and communicates with the spray holes.

[0024] By adopting the above technical solution, the spray pump is started, and the water in the spray box is sprayed out through the spray pipe and spray hole, so that the dust and water are mixed and flowed, thereby removing the dust.

[0025] Optionally, the discharge assembly includes:

[0026] A buffer tube is installed on the machine body and is in a horizontal position to catch dust and water passing through the filter plate. The buffer tube has multiple water passage holes with the same diameter as the filter holes and connected to the return flow component.

[0027] Drain pipes, installed on buffer pipes and sloping downwards, are used to discharge water and dust into drainage ditches.

[0028] By adopting the above technical solution, dust and water flow through the filter plate into the buffer pipe to form a certain buffer, which slows down the flow rate. This allows more water to enter the return component through the water inlet for recycling. Then, dust can enter the drain pipe under the push of the dust and water behind, and then fall down into the drainage ditch under the action of gravity for discharge. This achieves the discharge of dust and further improves the water collection effect, reduces the occurrence of water shortage, and greatly improves the dust removal efficiency and effect of the tunnel.

[0029] Optionally, both buffer tubes are provided with a suction assembly, the suction assembly comprising:

[0030] The suction tube is mounted on the buffer tube;

[0031] A water filter element, installed on the suction pipe, is used to remove water;

[0032] A fan is installed on the intake pipe to remove moisture-removing air.

[0033] By adopting the above technical solution, the fan starts, creating suction at the suction pipe. Dust around the suction pipe is drawn into the machine body under the suction force. Water sprays the dust and then enters the buffer pipe, where the water filter is used to filter the water. Air is blown out by the fan, further enhancing the dust absorption effect. Moreover, the baffle plate blocks dust and water, reducing the probability of dust and water moving to the water filter compared to direct entry into the fan. This reduces the probability of the water filter becoming clogged, thereby further improving the dust removal efficiency and effect in the tunnel.

[0034] Optionally, the suction pipe is provided with an enlarged end that expands outward to facilitate the entry of dust.

[0035] By adopting the above technical solution, more dust is drawn in, improving the efficiency and effectiveness of dust removal in the tunnel.

[0036] Optionally, the machine body is provided with a walking mechanism for propelling the machine body to move, the walking mechanism including:

[0037] Multiple movable seats are slidably mounted on the machine body along the direction close to or away from the tunnel sidewall;

[0038] A concentration detector, installed inside the suction pipe, is used to detect the dust concentration inside the tunnel.

[0039] Multiple support wheel sets are respectively mounted on multiple movable seats;

[0040] A driving component is used to drive multiple movable seats to move and to position multiple support wheel sets against the tunnel sidewall. The rotation of the multiple support wheel sets is used to drive the machine body to move and to control the moving speed of the machine body according to the dust concentration detected by the concentration detector.

[0041] By adopting the above technical solution, the multiple moving seats of the drive unit move, so that multiple support wheel sets press against the tunnel for positioning. The movement of multiple support wheel sets drives the machine body to move. The concentration detector detects the concentration and controls the moving speed of the machine body according to the concentration. The moving speed is faster when the concentration is low and slower when the concentration is high, thereby improving the dust removal efficiency and effect of the tunnel.

[0042] Optionally, the support wheel assembly includes:

[0043] Support rod one, set on the movable seat and tilted upwards, and rotatably mounted to press against the tunnel;

[0044] Support rod two, set on the movable seat and tilted downwards, and rotatably mounted on support wheel two that presses against the tunnel;

[0045] Two rotating components are respectively mounted on support rod one and support rod two and are electrically connected to the concentration detector to drive support wheel one and support wheel two to rotate.

[0046] By adopting the above technical solution, the rotating component drives support wheel one and support wheel two to rotate simultaneously, thereby driving the machine body to move. At the same time, support rod one and support rod two can distribute the pressure on the moving seat and increase the contact area with the tunnel, thereby improving the stability of the machine body during movement and improving the dust removal efficiency and effect on the tunnel.

[0047] In summary, this application includes at least one of the following beneficial technical effects:

[0048] By moving the machine inside the tunnel, dust suspended at the tunnel ceiling is drawn into the machine through the suction pipe. The spray system then sprays the dust, mixing it with water before it is discharged through the exhaust system. This method of cleaning up dust near its source significantly improves the efficiency and effectiveness of tunnel dust removal. Furthermore, the machine absorbs dust as it moves, eliminating the need for ductwork compared to extraction, thus saving time and further enhancing the efficiency and effectiveness of tunnel dust removal.

[0053] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0054] This application discloses an intelligent robot for rapid ventilation, smoke extraction, and dust suppression in long tunnels.

[0055] Reference Figure 1 and Figure 2 The intelligent control robot used for rapid ventilation, smoke removal and dust reduction in long tunnels includes a body 1 that walks on the top of the tunnel and a dust removal mechanism 2 installed on the body 1. The dust removal mechanism 2 is used to spray and discharge suspended dust, thereby removing dust in the tunnel. The body 1 is equipped with a walking mechanism 3 that propels the body 1 to walk.

[0056] The dust removal mechanism 2 includes a suction pipe 21. The body 1 is a shell structure. The suction pipe 21 is fixedly installed on one end of the body 1 and is connected to the inside of the body 1. The end of the suction pipe 21 away from the body 1 is provided with an outwardly enlarging end 22. The enlarging end 22 allows dust to enter the suction pipe 21 and enter the body 1 through the suction pipe 21.

[0057] The walking mechanism 3 includes multiple movable seats 31, a concentration detector 32, multiple support wheel sets 4, and a drive unit 33. The multiple movable seats 31 are distributed around the body 1 and move horizontally towards or away from the tunnel sidewall. The concentration detector 32 is fixedly installed inside the suction pipe 21 and is used to detect the dust concentration inside the suction pipe 21.

[0058] Multiple support wheel sets 4 are arranged one-to-one with multiple movable seats 31. The driving component 33 is an electric actuator, and multiple such actuators are arranged one-to-one with the multiple movable seats 31. The driving component 33 is connected to the movable seats 31. The multiple driving components 33 are activated simultaneously to drive the multiple movable seats 31 and the multiple support wheel sets 4 to move closer to the tunnel sidewall, so that the multiple support wheel sets 4 press against the tunnel sidewall for positioning. After the multiple support wheel sets 4 rotate, they are used to drive the machine body 1 to move. At the same time, the moving speed of the machine body 1 is determined according to the dust concentration detected by the concentration detector 32. When the dust concentration is higher than the specified value, the moving speed of the machine body 1 slows down, and when the dust concentration is lower than the specified value, the moving speed of the machine body 1 speeds up.

[0059] The support wheel assembly 4 includes a first support rod 41, a second support rod 42, and two rotating parts 43. One end of the first support rod 41 is fixedly installed on a section of the movable base 31 near the tunnel sidewall, and the other end of the first support rod 41 is inclined upward and rotatably mounted with a first support wheel 44. One end of the second support rod 42 is fixedly installed on a section of the movable base 31 near the tunnel sidewall, and the second support rod 42 is located below the first support rod 41. The other end of the second support rod 42 is inclined downward and rotatably mounted with a second support wheel 45. The first support wheel 44 and the second support wheel 45 press against the tunnel for positioning. The two rotating parts 43 are respectively fixedly installed on the first support rod 41 and the second support rod 42 and are used to drive the first support wheel 44 and the second support wheel 45 to rotate simultaneously, thereby moving the machine body 1 along the length of the tunnel. A control box for controlling the rotation speed of the rotating parts 43 is fixedly installed on the machine body 1. The control box is electrically connected to the concentration detector 32. The control box controls the rotation speed according to the dust concentration detected by the concentration detector 32, thereby controlling the movement speed of the machine body 1.

[0060] Reference Figure 1 and Figure 2 The dust removal mechanism 2 includes a spray assembly 5 and a discharge assembly 6. The body 1 moves so that dust in the tunnel enters the body 1 through the suction pipe 21. The spray assembly 5 is used to spray the dust, so that the dust and water are mixed. There are two discharge assemblies 6, which are corresponding to the tunnel sidewalls on both sides of the body 1. The two discharge assemblies 6 are used to discharge the dust and water mixture into the drainage ditches on both sides of the tunnel.

[0061] The end of the body 1 facing away from the suction pipe 21 is open and has an integrally installed baffle plate 11. The baffle plate 11 is located between the two discharge components 6 and is used to block the movement of dust, thereby slowing down the movement of dust and facilitating the spray component 5 to spray and remove the dust. An inclined guide plate 12 and an arched filter plate 13 are fixedly installed on the inner side wall of the body 1. The height of the guide plate 12 near the suction pipe 21 is lower than the height of the end away from the suction pipe 21, and the inner bottom wall of the suction pipe 21 is above the guide plate 12. The two ends of the filter plate 13 are fixedly installed on the inner bottom wall of the body 1. The filter plate 13 has multiple filter holes evenly opened on it to allow water to pass through and block dust from passing through. At the same time, the filter plate 13 extends to the bottom of the guide plate 12 away from the suction pipe 21. The filter plate 13 is located between the guide plate 12 and the baffle plate 11, and the two ends of the filter plate 13 near the two discharge components 6 are at the same height and the lowest point.

[0062] The spray assembly 5 is used to spray the dust on the guide plate 12 and the filter plate 13, so that the water and dust on the guide plate 12 move towards the filter plate 13 under the action of gravity. After the water and dust move onto the filter plate 13, they move towards the two discharge assemblies 6 under the action of gravity. At the same time, some water flows out through the filter holes. The body 1 is also provided with a return assembly 7 to return the water that has passed through the filter plate 13 to the spray assembly 5.

[0063] The spray assembly 5 includes a spray plate 51, a spray box 52, and a spray pump 53. The spray plate 51 is fixedly installed on the inner top wall of the machine body 1 and is in a horizontal state. The spray plate 51 is located above the guide plate 12 and the filter plate 13, and multiple spray holes are evenly opened on its lower surface. A rear mounting bracket 54 is fixedly installed on the lower surface of the machine body 1. The spray box 52 is fixedly installed on the mounting bracket 54 and is filled with spray water. The spray pump 53 is fixedly installed on the outer wall of the spray box 52 and communicates with the inside of the spray box 52. A spray pipe 55 is fixedly installed on the spray pump 53, which is fixedly connected to the spray plate 51 and communicates with the spray holes. When the spray pump 53 is started, the spray water is sprayed out through the spray pipe 55 and multiple spray holes to achieve the spraying and removal of dust in the air.

[0064] The discharge assembly 6 includes a buffer pipe 61 and a drain pipe 62. The two buffer pipes 61 are fixedly installed on the opposite side walls of the body 1 and are in a horizontal state. The two buffer pipes 61 are correspondingly set at both ends of the filter plate 13. Multiple water passage holes are evenly opened on the inner bottom wall of the buffer pipe 61, and the water passage holes have the same diameter as the filter holes. The water passage holes are connected to the return assembly 7, so that the water passing through the water passage holes also flows back into the spray assembly 5. The drain pipe 62 is integrally set on the end of the buffer pipe 61 away from the body 1, and the drain pipe 62 extends downward at an angle to the side wall of the tunnel.

[0065] Water and dust on the filter plate 13 move into the buffer tube 61. Since the buffer tube 61 is horizontal, the movement speed of water and dust is slowed down. This allows water to flow back into the spray assembly 5 through the water passage and the return assembly 7, while dust and some water continue to move into the drain pipe 62 and are finally discharged into the drainage ditch through the drain pipe 62. At the same time, the filter plate 13 can also prevent impurities that have moved into the buffer tube 61 from entering the return assembly 7.

[0066] The reflux assembly 7 includes a reflux hood 71 and a reflux pipe 72. The reflux hood 71 is fixedly installed on the lower surface of the body 1 and the buffer pipe 61, and the reflux hood 71 is in the shape of a bucket with a larger top and a smaller bottom. The reflux hood 71 is used to collect water that passes through the filter holes and water passage holes. The reflux pipe 72 is fixedly installed at the bottom of the reflux hood 71 and is fixedly connected to the upper surface of the spray box 52, so that the water in the reflux hood 71 flows back to the spray box 52 for collection through the reflux pipe 72.

[0067] Reference Figure 2 and Figure 3Each of the two buffer pipes 61 is equipped with a suction assembly 8, which includes a suction pipe 81, a water filter 82, and a fan 83. The two suction pipes 81 are respectively fixedly installed on the side wall of the two buffer pipes 61 away from the dust collection pipe 21, and the suction pipes 81 are arranged along the length of the machine body 1. The water filter 82 is fixedly installed inside the suction pipe 81 and is used to block water and allow air to pass through. The fan 83 is fixedly installed on the end of the suction pipe 81 away from the buffer pipe 61, and the two fans 83 are started at the same time, so that the dust in the tunnel is sucked into the dust collection pipe 21, allowing more dust to enter the machine body 1 for spray cleaning, while water is removed by the water filter 82, and air is output through the fan 83 and the suction pipe 81, thereby further improving the dust removal efficiency and effect of the tunnel.

[0068] The working principle of this application embodiment is as follows:

[0069] Multiple drive components 33 are activated simultaneously, causing support wheels 1 44 and 2 45 to press against the tunnel sidewall for positioning. Multiple rotating components 43 are activated simultaneously, driving the machine body 1 to move. At the same time, multiple fans 83 are activated, causing dust suspended in the tunnel to be sucked into the suction pipe 21. The dust moves to the spray plate 51, and the spray pump 53 is activated, causing water to spray out through the spray holes to spray the dust. At the same time, the dust moves to the baffle plate 11, which blocks the movement of the dust and slows down the movement speed. The dust and water mixture moves to the filter plate 13 under the action of the guide plate 12. The water flows back to the spray box 52 for recycling through the filter holes, return hood 71 and return pipe 72. At the same time, dust and some water are pushed into the buffer pipe 61. The water can continue to flow into the spray box 52 for recycling through the water passage hole. Finally, the dust and some water are discharged into the drainage ditches located on both sides of the tunnel through the drain pipe 62, thereby greatly improving the dust removal efficiency and effect of the tunnel.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
