Description

Technical Field

[0001] The utility model relates to the technical field of gas utilization and evacuation, and particularly relates to a gas evacuation device for construction tunnels. Background Technique

[0002] Tunnel construction refers to the engineering process of excavating and building tunnels underground or underwater. Such projects usually involve complex geological conditions and environmental factors and are mainly used in fields such as transportation (such as railways, highways), water conservancy projects, urban infrastructure, and mining. During tunnel construction, gas may exist inside. If this gas fails to be effectively controlled and treated, it may pose a great threat to construction safety. Therefore, a gas evacuation device is needed to extract and discharge the gas.

[0003] After retrieval, a patent with the Chinese patent application number CN215327947U discloses a gas utilization and evacuation device for a gas drainage station, including an air extraction pipe. One side of the outer surface of the air extraction pipe is fixedly connected to a sedimentation tank. One side of the outer surface of the sedimentation tank is fixedly connected to a fan. One side of the outer surface of the fan is fixedly connected to a buffer pipe. One side of the outer surface of the buffer pipe is fixedly connected to a gas storage tank. The other side of the outer surface of the sedimentation tank is fixedly connected to a water storage tank. One side of the upper surface of the water storage tank is fixedly connected to a generator;

[0004] Although in the above patent, through the cooperation of the air extraction pipe, sedimentation tank, fan, and water storage tank, the gas extracted by the air extraction pipe or other substances in it are drawn into the sedimentation tank. Water is poured over the sedimentation tank to extinguish some sparks. The filter screen in front of the fan filters some blocky objects or fine dust, and the debris box below can be cleaned and replaced at any time. However, there are still the following deficiencies in the use process: 1. Some substances will adhere to the filter screen, easily causing the filter screen to be blocked and difficult to clean, affecting the normal use of the device's functions; 2. The device is not convenient to move.

[0005] Therefore, there is an urgent need for a gas evacuation device for construction tunnels to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a gas evacuation device for construction tunnels to solve the problems raised in the above background technique.

[0007] In order to achieve the above invention purpose, the utility model provides the following technical solutions:

[0008] A gas evacuation device for construction tunnels includes a base. The top wall of the base is fixedly connected to a sedimentation tank. The outer wall of the sedimentation tank is fixedly connected to an air extraction pipe. The top wall of the base is also fixedly connected to an air extraction box, and further includes:

[0009] A push-pull handle, fixedly connected to the outer wall of the base;

[0010] Vibration anti-blocking assembly, the vibration anti-blocking assembly includes a filter pipe fixedly connected to the outer wall of the precipitation tank, the filter pipe is communicated with the air extraction box through a connecting pipe, symmetrically distributed telescopic rods are fixedly connected to the inner wall of the filter pipe, and the end of the telescopic rod away from the filter pipe is fixedly connected to a vibration pipe. A filter plate is fixedly connected to the outer wall of the vibration pipe. A first strong spring is sleeved on the outer wall of the telescopic rod, and the first strong spring is fixedly connected to the vibration pipe. The end of the first strong spring away from the vibration pipe is fixedly connected to the filter pipe. Symmetrically distributed connecting plates are fixedly connected to the outer wall of the filter pipe. The end of the connecting plate away from the filter pipe is fixedly connected to a driving motor. Symmetrically distributed driving wheels are rotatably connected to the outer wall of the filter pipe, and the output end of the driving motor is fixedly connected to the driving wheel. Two groups of driven wheels are rotatably connected to the outer wall of the filter pipe. The driven wheels and the driving wheels are connected by a belt drive. An extrusion block is fixedly connected to the outer wall of the driving wheel, and the outer wall of the extrusion block abuts against the outer wall of the vibration pipe;

[0011] Buffer assembly, arranged on the outer wall of the base.

[0012] As a preferred technical solution of the present application, the buffer assembly includes fixed columns symmetrically and fixedly connected to the outer wall of the base. Uniformly distributed sliding blocks are slidably connected to the outer wall of the fixed columns on the same side. A lifting plate is fixedly connected between the sliding blocks on the same side. Uniformly distributed second strong springs are fixedly connected between adjacent lifting plates. A sliding sleeve is slidably connected to the outer wall of the fixed column, and the top wall of the sliding sleeve is fixedly connected to the sliding block. A universal wheel is fixedly connected to the end of the sliding sleeve away from the sliding block.

[0013] As a preferred technical solution of the present application, a wind collecting plate is fixedly connected to the inner wall of the air extraction box, a fan is also fixedly connected to the inner wall of the air extraction box, and a controller is rotatably connected to the outer wall of the wind collecting plate.

[0014] As a preferred technical solution of the present application, an air storage tank is fixedly connected to the top wall of the base, a pressure gauge is fixedly connected to the top wall of the air storage tank, the air storage tank is communicated with the air extraction box through a slow air pipe, and an observation window is arranged on the top wall of the slow air pipe.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] In the solution of the present application:

[0018] 1. By setting the output end of the drive motor to drive the drive wheel to rotate, and transmitting the power to the drive wheel on the other side through a belt, the synchronous rotation of the extrusion blocks on both sides is realized. These extrusion blocks will alternately extrude the vibration tube, causing the vibration tube to vibrate inside the filter tube, and thus the filter plate will also vibrate accordingly. This mechanism can effectively help the substances attached to the filter plate to fall off, prevent the filter plate from being blocked, and ensure the normal operation of the equipment function. This method solves the problem that some substances on the filter net in the prior art are likely to adhere and cause blockage;

[0019] 2. By setting multiple universal wheels, the equipment can be moved flexibly. At the same time, multiple lifting plates slide on the fixed columns through sliding blocks. When the universal wheels encounter a bumpy road surface, the sliding sleeve will squeeze the sliding block, and then squeeze to shorten the distance between the lifting plates, and then compress the second strong spring. The compressed second strong spring will generate a reaction force, acting on the lifting plate, so as to offset the extrusion force of the lifting plate. This mechanism effectively reduces the bumpiness of the equipment during the movement process, and at the same time reduces the risk brought by the flow of the stored gas, improves safety, and solves the problem that the device in the prior art is not easy to move.

[0028] For the purposes, technical solutions and advantages of the embodiments of the present utility model to be clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model.

[0029] As Figure 1-6 shown, an exhaust gas equipment for construction tunnels proposed in this embodiment includes a base 1, a precipitation tank 2 fixedly connected to the top wall of the base 1, an air extraction pipe 10 fixedly connected to the outer wall of the precipitation tank 2, and an air extraction box 6 fixedly connected to the top wall of the base 1. It further includes:

[0030] A push-pull handle 8 fixedly connected to the outer wall of the base 1;

[0031] A vibration anti-clogging component, the vibration anti-clogging component includes a filter tube 12 fixedly connected to the outer wall of the sedimentation box 2, the filter tube 12 is connected to the exhaust box 6 through a connecting tube 15, the inner wall of the filter tube 12 is fixedly connected with a symmetrically distributed telescopic rod 18, the end of the telescopic rod 18 away from the filter tube 12 is fixedly connected with a vibration tube 16, the outer wall of the vibration tube 16 is fixedly connected with a filter plate 17, the outer wall of the telescopic rod 18 is sleeved with a first strong spring 19, and the first strong spring 19 is fixedly connected to the vibration tube 16, the end of the first strong spring 19 away from the vibration tube 16 is fixedly connected to the filter tube 12, the outer wall of the filter tube 12 is fixedly connected with a symmetrically distributed connecting plate 20, the end of the connecting plate 20 away from the filter tube 12 is fixedly connected with a driving motor 21, the outer wall of the filter tube 12 is rotatably connected with a symmetrically distributed driving wheel 22, and the output end of the driving motor 21 is fixedly connected to the driving wheel 22, the outer wall of the filter tube 12 is rotatably connected with two groups of driven wheels 24, the driven wheel 24 The drive wheel 22 is connected to the drive wheel 22 through a belt 25. The outer wall of the drive wheel 22 is fixedly connected with an extrusion block 23, and the outer wall of the extrusion block 23 is against the outer wall of the vibration tube 16. The output end of the drive motor 21 drives the drive wheel 22 connected to the output end of the drive motor 21 to rotate, and the belt 25 is used to transmit the rotation to the driven wheel 24 and the drive wheel 22 on the other side, so that the extrusion blocks 23 connected to the two drive wheels 22 can rotate. Due to the special structure of the extrusion blocks 23, when the extrusion blocks 23 rotate, they will squeeze the vibration tube 16 in turn to move in the filter tube 12, so as to achieve the extrusion vibration of the vibration tube 16. There is a thin rubber body (not marked in the figure) at the contact point between the vibration tube 16 and the filter tube 12, which can be pulled and deformed arbitrarily when following the movement of the vibration tube 16, and play a sealing role. When the vibration tube 16 vibrates, it drives the filter plate 17 to vibrate, so as to achieve the vibration and fall off of the material attached to the filter plate 17, so as to ensure the normal operation of the equipment.

[0032] The buffer component is arranged on the outer wall of the base 1 .

[0033] like Figure 6As shown, as a preferred embodiment, on the basis of the above method, further, the buffer assembly includes fixed columns 26 symmetrically and fixedly connected to the outer wall of the base 1. Sliding blocks 27 are evenly distributed and slidably connected to the outer walls of the fixed columns 26 on the same side. A lifting plate 28 is fixedly connected between the sliding blocks 27 on the same side. Second strong springs 29 are evenly distributed and fixedly connected between adjacent lifting plates 28. A sliding sleeve 30 is slidably connected to the outer wall of the fixed column 26, and the top wall of the sliding sleeve 30 is fixedly connected to the sliding block 27. A universal wheel 31 is fixedly connected to the end of the sliding sleeve 30 away from the sliding block 27. The device is moved through the universal wheel 31. When the universal wheel 31 encounters a bumpy road section, it is pushed by the protruding part of the bumpy road section to slide the sliding sleeve 30 on the fixed column 26, and then squeeze the sliding block 27 to slide on the fixed column 26, thereby driving the lifting plate 28 to move. When the lifting plate 28 moves, it will squeeze and shorten the distance between the second strong springs 29. The second strong springs 29 will be compressed and deformed under extrusion and react on the lifting plate 28, thereby offsetting the extrusion impact force brought by the lifting plate 28 and reducing the bump of the device.

[0034] As Figure 2 shown, as a preferred embodiment, on the basis of the above method, further, a wind collecting plate 13 is fixedly connected to the inner wall of the air extraction box 6, and a fan 14 is also fixedly connected to the inner wall of the air extraction box 6. A controller 7 is rotatably connected to the outer wall of the wind collecting plate 13. By rotating the controller 7, the fan 14 operates. When the fan 14 operates, it will generate air extraction. The wind carries gas and substances into the precipitation tank 2 through the air extraction pipe 10. The spiral structure of the wind collecting plate 13 can accelerate the wind speed.

[0035] As Figure 1 shown, as a preferred embodiment, on the basis of the above method, further, an air storage tank 3 is fixedly connected to the top wall of the base 1, a pressure gauge 4 is fixedly connected to the top wall of the air storage tank 3, and the air storage tank 3 is connected to the air extraction box 6 through a buffer pipe 5. An observation window 11 is arranged on the top wall of the buffer pipe 5 to check the operation status of the device through the observation window 11.

[0036] As Figure 1 shown, as a preferred embodiment, on the basis of the above method, further, a debris box 9 is slidably connected to the inner wall of the precipitation tank 2 to collect the impurities filtered by the filter plate 17 through the debris box 9.

[0037] Specifically, when the gas drainage equipment for the construction tunnel is in use: First, the equipment is moved by pushing the push-pull handle 8. Specifically, the equipment is moved by the universal wheels 31. When the universal wheels 31 encounter a bumpy road section, they are squeezed by the protruding parts of the bumpy road section, thereby pushing the sliding sleeve 30 to slide on the fixed column 26, and then squeezing the sliding block 27 to slide on the fixed column 26, and then driving the lifting plate 28 to move. When the lifting plate 28 moves, it will squeeze and shorten the distance between the second strong springs 29. The second strong springs 29 will be compressed and deformed under the extrusion and react on the lifting plate 28, so as to offset the extrusion impact force brought by the lifting plate 28 and reduce the bumpiness of the equipment; The fan 14 is operated by rotating the controller 7. When the fan 14 operates, it will generate suction. The wind carries gas and substances into the sedimentation tank 2 through the suction pipe 10. The substances will stay on the filter plate 17 and part of the substances will fall into the debris box 9 by carrying the substances through an external water pipe (not shown in the figure). The gas passes through the filter plate 17 and enters the vibration pipe 16, and then passes through the connecting pipe 15, the suction box 6, and the buffer pipe 5, and finally enters the gas storage tank 3 for storage. When some substances adhere to the filter plate 17 and are difficult to fall off, at this time, the output end of the driving motor 21 drives the driving wheel 22 connected to the output end of the driving motor 21 to rotate, and is transmitted to the driven wheel 24 and the driving wheel 22 on the other side through the belt 25 to rotate, so as to realize the rotation of the extrusion block 23 connected by the two driving wheels 22. Due to the special structure of the extrusion block 23, when the extrusion block 23 rotates, it will alternately squeeze the vibration pipe 16 to move in the filter pipe 12, so as to realize the extrusion vibration of the vibration pipe 16. There is a thin rubber body (not shown in the figure) at the contact between the vibration pipe 16 and the filter pipe 12, which can be arbitrarily stretched and deformed when following the movement of the vibration pipe 16 to play a sealing role. When the vibration pipe 16 vibrates, it drives the filter plate 17 to vibrate, so as to realize the vibration and falling off of the substances attached to the filter plate 17 and ensure the normal operation of the equipment.

Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
