Description

Technical Field

[0001] The present invention relates to the technical field of tunnel drainage, and in particular to a tunnel water cleaning device and a control method thereof. Background Art

[0002] Tunnel excavation is a crucial step in many engineering fields, including water conservancy, hydropower, transportation, and mining. During blasting and excavation, water may seep into certain areas, forming puddles within the tunnel. These accumulated water are difficult to drain through the tunnel's drainage system. Therefore, before pouring the base slab, the accumulated water and gravel must be thoroughly removed to prevent problems such as loose concrete bonds and reduced strength.

[0003] Chinese patent CN221503355U discloses a tunnel construction drainage device, comprising a mobile vehicle, a filter assembly, and several vibrating mechanisms. The mobile vehicle is equipped with a water tank, which is connected to a water suction pipe via a water suction pump. The water suction pipe is a flexible hose and is connected to a water suction head, which is used to contact water in the external environment to absorb water. The filter assembly includes several filter balls, and the water suction end of the water suction head is provided with a plurality of water suction holes. The water suction holes correspond one to one with the filter balls, and the outer walls of the filter balls are tightly connected to the hole walls of the corresponding water suction holes, so that the water suction holes are connected to the external environment through the filter balls. The vibrating mechanism is located within the filter balls to vibrate the filter balls. However, the environment inside the tunnel after blasting excavation is complex, and the scattered gravel varies in size. Using a water suction pump to clean the accumulated water may cause the gravel with smaller particle diameters to be sucked into the water suction pipe, causing damage to the internal structure. If the pores of the filter balls are too dense, it is difficult to ensure the efficiency of the accumulated water cleaning.

[0004] Therefore, manual cleaning methods are still widely used in the industry, such as workers manually sorting gravel and using rags or sponges to absorb accumulated water. This method is not only inefficient but also difficult to guarantee cleaning results due to factors such as the harsh environment inside the tunnel. Furthermore, the high labor costs seriously affect construction progress. Summary of the Invention

[0050] See also Figures 1 to 4, this embodiment provides a tunnel water cleaning device, including a mobile vehicle body 1 and a lifting arm, the mobile vehicle body 1 is rotatably connected to the lifting arm, and also includes a rotating shaft 12, a roller 6, a first water absorption component 10 and a second water absorption component; the roller 6 is connected to the lifting arm, and the roller 6 is separated from the rotating shaft 12; the mobile vehicle body 1 is provided with a water tank, and a water removal bucket 11 for accommodating the roller 6 is provided above the water tank, and the water removal bucket 11 includes two cross-arranged extrusion plates, and a water inlet is provided between the two extrusion plates and connected to the water tank, and when the roller 6 is located inside the water removal bucket 11, the roller 6 abuts against the extrusion plates; wherein, the rotating shaft 12 is rotatably connected to the mobile vehicle body 1, and the roller 6 is provided with an opening for the second water absorption component to pass through; the first water absorption component 10 is connected to the outer wall of the roller 6; the second There are multiple water absorption components, and multiple second water absorption components are arranged in sequence along the length direction of the rotating shaft 12. Each second water absorption component includes a first driving mechanism, a transmission component and a water absorption unit 13. The first driving mechanism is a telescopic cylinder, including a fixed end and a telescopic end arranged relatively, the fixed end is connected to the rotating shaft 12 and moves synchronously with the rotating shaft 12, the transmission component is connected to the telescopic end, and the water absorption unit 13 is connected to the transmission component and moves synchronously with the transmission component; wherein, when the water absorption unit 13 is located on the outside of the first water absorption component 10, it is used to absorb accumulated water in the puddle; when the transmission component and the roller 6 are connected to each other, the transmission component pushes the roller 6 to rotate around the rotating shaft 12, and the water absorption unit 13 and the first water absorption component 10 together form an annular water absorption structure.

[0051] Specifically, the rotating shaft 12 in this embodiment is connected to the drive motor 20 and rotates under the drive of the drive motor 20. The transmission component is preferably a transmission plate, and the thickness of the transmission plate is greater than the thickness of the roller 6, so that the rotation of the roller 6 is more stable. The material of the first water absorption component 10 and the water absorption unit 13 is preferably sponge.

[0052] In this embodiment, the first water absorption component 10 and the water absorption unit 13 absorb the accumulated water in the tunnel. Since the first water absorption component 10 and the water absorption unit 13 are flexible, the influence of the gravel retained in the tunnel on the water removal performance can be significantly reduced; the second water absorption component is set up, when facing a puddle in the tunnel, the second water absorption component can extend into the puddle, and the second water absorption component specifically absorbs the accumulated water in the puddle; the roller 6 has several second water absorption components distributed axially, which can adapt to puddles of different depths and shapes, so that the second water absorption component can touch the bottom as much as possible to remove water, thereby improving the water removal performance.

[0053] This embodiment further includes a water collecting hopper 19 and a first drain pipe for collecting the accumulated water in the second water absorbing assembly, wherein the water collecting hopper 19 is fixed to the inner wall of the roller 6; wherein, when the water absorbing unit 13 is located on the inner side of the opening, the water absorbing unit 13 follows the rotating shaft 12 to move to the top of the water collecting hopper 19, and the first driving mechanism drives the water absorbing unit 13 to move toward the inner wall of the roller 6 to squeeze out the accumulated water absorbed by the water absorbing unit 13 and flow it into the water collecting hopper 19; the bottom of the water collecting hopper 19 is also provided with a drainage hole, which is connected to the first drain pipe, the length of the first drain pipe is less than the radius of the roller 6, and the mouth of the water collecting hopper 19 is provided with an openable and closable sealing cover. There are many types of openable and closable structures of sealing covers in the prior art, and this embodiment is the simplest one, which uses a motor to start the hinge rotation of the sealing cover to achieve opening and closing.

[0054] More specifically, both ends of the water collecting hopper 19 are connected to the two side walls of the roller 6, and the angle between the water collecting hopper 19 and the telescopic cylinder is greater than or equal to 240° to 310°. In this embodiment, the angle between the water collecting hopper 19 and the telescopic cylinder is 270°. After the accumulated water absorbed in the water absorption unit 13 reaches the preset water content, the telescopic cylinder retracts the water absorption unit 13 into the inside of the roller 6, and the rotating shaft 12 rotates clockwise to drive the second water absorption component to rotate until the water absorption unit 13 is located above the water collecting bucket 19. The sealing cover of the water collecting bucket 19 is opened, and the telescopic cylinder extends to squeeze the water absorption unit 13 on the inner wall of the roller 6. The internal accumulated water flows into the water collecting bucket 19 along the inner wall of the roller 6. The water collecting bucket 19 is used to temporarily collect the accumulated water. After the water in the water collecting bucket 19 is full, the first drain pipe is opened to let the accumulated water leak out from the drain hole of the water collecting bucket 19 to complete the drainage, thereby avoiding the heavier roller 6 requiring the lifting arm to frequently lift the roller 6 for dewatering, which causes increased energy consumption and component fatigue deformation.

[0055] Furthermore, it also includes an air pump 18. The interior of the rotating shaft 12 is hollow to form an air chamber. The air pump 18 is connected to the air chamber. A connecting hole is provided between the air chamber and the first driving mechanism, and a valve is provided in the connecting hole. The various telescopic cylinders are connected through the air chamber inside the rotating shaft 12, so that the function of synchronously controlling all water absorption units 13 with one button can be realized. The connection between the air chamber and the telescopic cylinder can also be blocked by a valve to realize the function of independently controlling a single or multiple second water absorption components. The rotating shaft 12 in this embodiment passes through the inside of both sides of the roller 6, and the rotating shaft 12 is connected to the lifting arm. The lifting arm is connected to the roller 6 to support the roller 6. The driving motor 20 and the air pump 18 are respectively fixed on the lifting arms on both sides.

[0056] In this embodiment, as a further preferred embodiment, the telescopic cylinder includes an outer cylinder 14, an inner cylinder 15, a compression spring 16, and a telescopic rod 17. The inner cylinder 15 is slidably connected to the outer cylinder 14. The top of the outer cylinder 14 is connected to the air chamber. A limiting structure is provided between the outer cylinder 14 and the inner cylinder 15. The compression spring 16 and the telescopic rod 17 are connected to the inner cylinder 15. One end of the telescopic rod 17 is connected to the compression spring 16, and the other end of the telescopic rod 17 extends out of the inner cylinder 15 and is connected to the transmission assembly. The compression spring 16 in the inner cylinder 15 not only provides a buffer but also limits the return position of the telescopic rod 17. When the telescopic rod 17 pushes the water absorption unit 13 into the puddle and touches the bottom, the elastic contact of the compression spring 16 can cause the transmission assembly to tilt at a certain angle, thereby adapting to more complex puddles and further improving the water removal performance.

[0057] In one embodiment, the squeezing plate in the dewatering hopper 11 is curved, with a gradually increasing curvature from the entry end of the roller 6. The curvature of the squeezing plate gradually increases. After the roller 6 enters the dewatering hopper 11, as the roller 6 moves downward, the squeezing plate gradually squeezes the first water absorbing assembly 10 and the water absorbing unit 13 until the roller 6 reaches the bottom of the dewatering hopper 11, where the squeezing force reaches its maximum. The roller 6 then rotates to continuously change the squeezing area, and the accumulated water is continuously discharged into the water tank, thereby completing the dewatering work of the entire roller.

[0058] In one embodiment, the lifting arm includes a connecting arm 5, a gear set, a rack 9 and a cylinder 7. The two ends of the connecting arm 5 are respectively rotatably connected to the roller 6 and the mobile vehicle body 1. The gear set is fixedly connected to the connecting arm 5 at one end of the mobile vehicle body 1. The cylinder 7 is fixed on one side of the mobile vehicle body 1, and the extended end of the cylinder 7 points to the side of the roller 6. The rack 9 is fixed on the extended end of the cylinder 7, and the rack 9 is engaged with the gear set.

[0059] In this embodiment, the gear train consists of a fixed gear 8 and a transmission gear 21. The transmission gear 21 is a stepped gear. The pinion of the transmission gear 21 meshes with the rack 9, while the larger gear of the transmission gear 21 meshes with the fixed gear 8. In this embodiment, the retraction of the cylinder 7 drives the rack 9 backward, which, through the transmission gear 21, drives the connecting arm 5 to lift the roller 6. The roller 6 rotates around the fixed gear 8 and enters the dewatering bucket 11. The meshing of the rack 9 and the gear train drives the connecting arm 5, resulting in a reliable and stable connection, greater load capacity, and reduced fatigue damage.

[0060] In another embodiment, the lifting of the connecting arm 5 may also be achieved by direct motor drive or motor drive gear set.

[0061] In one embodiment, the mobile vehicle further includes a sludge pump 2, a sludge suction port, a sludge pipe 4, and a sludge tank 3. The sludge pipe 4 connects the sludge suction port, the sludge pump 2, and the sludge tank 3 in sequence. The sludge suction port is located at the rear of the mobile vehicle body 1 and faces downward. In this embodiment, the sludge pump 2 and the sludge tank 3 are fixed to the top of the mobile vehicle body 1 for easy cleaning and maintenance. After the first water suction assembly 10 and the water suction unit 13 remove the accumulated water, the mobile vehicle body 1 moves forward, and the sludge suction port at the rear removes the sludge and gravel together, further improving cleaning efficiency.

[0062] In the above embodiment, a sensor for detecting water content and a central processing unit are preferably further included. The sensor is installed in the first water absorption assembly 10 and the water absorption unit 13, respectively, and is connected to the central processing unit. The sensor detects the water content of the first water absorption assembly 10 and the water absorption unit 13, and the central processing unit determines the water removal mode and timing based on the water content, thereby improving the automation level of this embodiment.

[0063] In this embodiment, the sensor can be a capacitive sensor. The principle is that the dielectric constant of accumulated water is much higher than that of air. The capacitance value of the first water absorption component 10 and the water absorption unit 13 will change significantly after absorbing water. The water removal mode and water removal timing are judged by comparing the capacitance value with the preset threshold.

[0064] like Figure 5 As shown, this embodiment also provides a control method for a tunnel water cleaning device, which is applied to the puddle water removal mode of the tunnel water cleaning device as described above, and includes the following steps:

[0065] S1. Obtain current water accumulation information on the tunnel ground, and determine whether there is a puddle on the tunnel ground that meets preset conditions based on the current water accumulation information; the current water accumulation information includes depth, and the preset condition is whether the depth is greater than the thickness of the first water absorption component 10. When the depth is greater than the thickness of the first water absorption component 10, it is determined that a puddle exists, and the mode is switched to puddle dewatering mode.

[0066] In one embodiment, the mobile vehicle 1 is further provided with an image collector connected to a central processing unit. The image collector captures real-time images of water accumulation on the tunnel floor ahead of the mobile vehicle 1's path. The central processing unit determines the depth of water accumulation on the tunnel floor by comparing the grayscale value of the water accumulation image with a preset grayscale value. The specific determination process is conventional and will not be elaborated on here.

[0067] S2. When a puddle that meets preset conditions exists on the tunnel floor, the roller 6 is controlled to move to directly above the puddle, and then the roller 6 is controlled to rotate so that the opening corresponds to the puddle. Specifically, if the opening does not correspond to the puddle after the roller 6 moves to directly above the puddle, the roller 6 is rotated idle until the opening corresponds to the puddle.

[0068] S3. According to the current water accumulation information, the first driving mechanism is controlled to move in a direction away from the rotating shaft 12 to drive the second water absorbing component to extend out of the opening. After a preset time is reached, the first driving mechanism is controlled to move in a direction close to the rotating shaft 12 to retract the second water absorbing component to the inner side of the opening; specifically, the movement stroke of the first driving mechanism is controlled according to the depth, so as to achieve precise control of the second water absorbing component.

[0069] S4. Obtain the water content of each of the water absorption units 13, determine the maximum water content of all the water absorption units 13, and judge whether the maximum water content reaches a preset water content.

[0070] S5. When the maximum value does not reach the preset water content, it is determined that the accumulated water in the puddle has been completely sucked out, and the process returns to step S1, and the mobile vehicle body 1 continues to move forward.

[0071] S6. When the maximum value reaches a preset water content, the second water absorption component is controlled to remove water, and then the process returns to step S3.

[0072] Furthermore, the step S3 specifically includes the following steps:

[0073] S31 , obtaining the width of the puddle; and determining whether the width of the puddle is greater than the width of one water absorption unit 13 .

[0074] S32. When the width of the water puddle is greater than the width of one water absorbing unit 13, the roller 6 is controlled to move to directly above the water puddle, and then the roller 6 is rotated so that the opening corresponds to the water puddle.

[0075] S33. According to the current water accumulation information and the width of the puddle, a corresponding number of the first driving mechanisms are controlled to move in a direction away from the rotating shaft 12 to drive the second water absorbing assembly to extend out of the opening. After a preset time is reached, the first driving mechanism is controlled to return to retract the second water absorbing assembly; wherein, in the second water absorbing assembly extending out of the opening, the sum of the widths of the water absorbing units 13 matches the width of the puddle.

[0076] Further preferably, in step S33, a corresponding number of the first driving mechanisms are controlled to move in a direction away from the rotating shaft 12 according to the width of the puddle, so as to drive the second water absorbing assembly to extend out of the opening, specifically:

[0077] When the width of the water puddle is greater than n times the width of the single water absorbing unit 13 and less than n+1 times the width of the single water absorbing unit 13, n first driving mechanisms are controlled to move away from the rotating shaft 12 to drive the second water absorbing assembly to extend out of the opening; where n is a positive integer, n ≥ 1. For example, when the width of the water puddle is 2.5 times the width of the water absorbing unit 13, two first driving mechanisms are controlled to move away from the rotating shaft 12 to drive the second water absorbing assembly to extend out of the opening.

[0078] Furthermore, controlling the second water absorbing component to remove water in step S6 specifically includes the following steps:

[0079] S61. Control all first drive mechanisms to move in the direction close to the rotating shaft 12 to move the second water absorption component to the inside of the roller 6, control the rotating shaft 12 to rotate in the opposite direction of the bucket mouth of the water collecting bucket 19 until the water absorption unit 13 is located above the bucket mouth of the water collecting bucket 19, and open the sealing cover.

[0080] S62 , controlling the first driving mechanism to move in a direction away from the rotating shaft 12 , squeezing the water absorption unit 13 , so that the accumulated water in the water absorption unit 13 flows into the water collecting bucket 19 .

[0081] S63 , controlling the first driving mechanism to move toward the direction close to the rotating shaft 12 , and controlling the rotating shaft 12 to reverse, so that the second water absorbing assembly corresponds to the opening, and the water collecting bucket 19 is closed.

[0082] S64: Control the first driving mechanism to move in a direction away from the rotating shaft 12 to return the second water absorbing assembly to the opening.

[0083] In another embodiment, a control method for a tunnel water cleaning device is provided, which is applied to the tunnel water cleaning device as described above, and includes the following steps:

[0084] S1. Obtain current water accumulation information on the tunnel ground, and determine whether there is a puddle on the tunnel ground that meets preset conditions based on the current water accumulation information.
