Description

Technical Field

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

[0002] In many engineering fields such as water conservancy and hydropower, transportation, and mining, tunnel excavation is a crucial link. During the process of blasting excavation, water seepage may occur in some areas, forming puddles in the tunnel. The accumulated water in the puddles is difficult to be drained through the drainage system in the tunnel. Therefore, before the bottom slab is poured, the accumulated water and gravel at the bottom slab position need to be thoroughly cleared to avoid problems such as poor bonding of concrete and reduced strength.

[0003] Chinese Patent CN221503355U discloses a drainage device for tunnel construction, including a mobile vehicle, a filtering component, and several vibration mechanisms. The mobile vehicle is provided with a water tank, and the water tank is connected to a suction pipe through a water suction pump. The suction pipe is a flexible pipe, and the suction pipe is connected to a suction head, and the suction head is used to contact the water body in the external environment to suck water; the filtering component includes several filter tennis balls. The suction end of the suction head is provided with several suction holes, and the suction holes correspond to the filter tennis balls one by one. The outer wall of the filter tennis ball is tightly connected to the hole wall of the corresponding suction hole, so that the suction hole is communicated with the external environment through the filter tennis ball; the vibration mechanism is arranged inside the filter tennis ball to vibrate the filter tennis ball. However, the environment inside the tunnel after blasting excavation is complex, and the scattered gravel has different sizes. Clearing the accumulated water by the method of sucking water through a water suction pump may cause gravel with a smaller particle diameter to be sucked into the suction pipe, damaging the internal structure. If the pores of the filter tennis ball are too dense, it is difficult to ensure the efficiency of cleaning the accumulated water.

[0004] Therefore, the manual cleaning method is still generally adopted in the current industry, such as workers manually picking gravel, using a rag or sponge to absorb the accumulated water, etc. This method not only has low efficiency, but also is limited by factors such as the harsh environment inside the tunnel, and it is difficult to ensure the cleaning effect. At the same time, the labor cost is high, seriously affecting the construction progress. Summary of the Invention

[0013] Further, the step S3 specifically includes the following steps: S31.

[0025] Please refer to Figures 1 to 4 , this embodiment provides a tunnel water accumulation cleaning device, including a mobile vehicle main body 1 and a lifting arm. The mobile vehicle main body 1 is rotatably connected to the lifting arm, and further includes a rotating shaft 12, a roller 6, a first water absorption assembly 10, and a second water absorption assembly. The roller 6 is connected to the lifting arm and separated from the rotating shaft 12. The mobile vehicle main body 1 is provided with a water tank, and above the water tank is a water removal hopper 11 for accommodating the roller 6. The water removal hopper 11 includes two cross - arranged pressing plates, and there is a water inlet between the two pressing plates communicating with the water tank. When the roller 6 is located inside the water removal hopper 11, the roller 6 abuts against the pressing plates. Among them, the rotating shaft 12 is rotatably connected to the mobile vehicle main body 1, and the roller 6 is provided with an opening through which the second water absorption assembly passes. The first water absorption assembly 10 is connected to the outer wall of the roller 6. The number of the second water absorption assemblies is multiple, and the multiple second water absorption assemblies are arranged in sequence along the length direction of the rotating shaft 12. Each second water absorption assembly includes a first driving mechanism, a transmission assembly, and a water absorption unit 13. The first driving mechanism is a telescopic cylinder, including a fixed end and a telescopic end arranged oppositely. The fixed end is connected to the rotating shaft 12 and moves synchronously with the rotating shaft 12. The transmission assembly is connected to the telescopic end, and the water absorption unit 13 is connected to the transmission assembly and moves synchronously with the transmission assembly. Among them, when the water absorption unit 13 is located outside the first water absorption assembly 10, it is used to suck the accumulated water in the puddle. When the transmission assembly is connected to the roller 6, the transmission assembly pushes the roller 6 to rotate around the rotating shaft 12, and the water absorption unit 13 and the first water absorption assembly 10 jointly form an annular water absorption structure.

[0026] Specifically, the rotating shaft 12 in this embodiment is connected to a driving motor 20 and rotates under the drive of the driving motor 20. The transmission assembly is preferably a transmission plate, and the thickness of the transmission plate is greater than the thickness of the roller 6, making the rotation of the roller 6 more stable. The materials of the first water absorption assembly 10 and the water absorption unit 13 are preferably sponge.

[0027] In this embodiment, the first water absorption component 10 and the water absorption unit 13 are used to suck out 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 remaining in the tunnel on their water removal performance can be significantly reduced; the setting of the second water absorption component enables the second water absorption component to extend into the puddle in the tunnel when facing the puddle in the tunnel, and the second water absorption component specifically sucks out the accumulated water in the puddle; a number of second water absorption components are axially distributed on the roller 6, which can adapt to puddles of different depths and shapes, enabling the second water absorption component to touch the bottom as much as possible for water removal and improving the water removal performance.

[0028] Further in this embodiment, it further includes a water collecting hopper 19 for collecting the accumulated water in the second water absorption component and a first drain pipe. The water collecting hopper 19 is fixed to the inner wall of the roller 6; wherein, when the water absorption unit 13 is located inside the opening, the water absorption unit 13 moves to the upper part of the water collecting hopper 19 following the rotation of the rotating shaft 12, and the first driving mechanism drives the water absorption unit 13 to move towards the inner wall of the roller 6 to squeeze out the accumulated water absorbed by the water absorption unit 13 and flow it into the water collecting hopper 19; a drain hole is further provided at the bottom of the water collecting hopper 19, and the drain hole is connected to the first drain pipe. The length of the first drain pipe is less than the radius of the roller 6, and an openable and closable sealing cover is provided at the mouth of the water collecting hopper 19. There are various existing technologies for the openable and closable structure of the sealing cover. In this embodiment, the simplest one is adopted, and the hinge of the sealing cover is rotated by an electric motor to achieve opening and closing.

[0029] 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 position where the water collecting hopper 19 is located and the telescopic cylinder is greater than or equal to 240° - 310°. In this embodiment, the angle between the position where the water collecting hopper 19 is located 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 roller 6. 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 hopper 19. The sealing cover of the water collecting hopper 19 is opened, and the telescopic cylinder extends to squeeze the water absorption unit 13 against the inner wall of the roller 6. The internal accumulated water flows along the inner wall of the roller 6 into the water collecting hopper 19. The water collecting hopper 19 is used for temporarily collecting the accumulated water. After the accumulated water in the water collecting hopper 19 is full, the first drain pipe is opened to drain the accumulated water from the drain hole of the water collecting hopper 19, completing the drainage, and avoiding the need to frequently lift the heavy roller 6 by the lifting arm for water removal, which causes increased energy consumption and fatigue deformation of components.

[0030] Further, it further includes an air pump 18. The inside of the rotating shaft 12 is hollow to form an air chamber. The air pump 18 is communicated with the air chamber. A communication hole is provided between the air chamber and the first driving mechanism, and a valve is provided in the communication hole. The air chamber inside the rotating shaft 12 is used to communicate each telescopic cylinder, so as to realize the function of synchronously controlling all the water suction units 13 with one key. The communication between the air chamber and the telescopic cylinder can also be blocked by the valve to realize the function of independently controlling a single or multiple second water suction components. In this embodiment, the rotating shaft 12 passes out from both sides inside the roller 6. The rotating shaft 12 is connected to the lifting arm, and 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.

[0031] In this embodiment, as a further preference, 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 inside the outer cylinder 14. The top of the outer cylinder 14 is communicated with 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 inside 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 can not only provide buffering, but also limit the return position of the telescopic rod 17. When the telescopic rod 17 pushes the water suction unit 13 into the puddle and touches the bottom, the elastic contact of the compression spring 16 can make the transmission assembly tilt at a certain angle, so as to adapt to puddles with more complex shapes and further improve the water removal performance.

[0032] In one embodiment, the pressing plate in the water removal hopper 11 is an arc with a gradually increasing radian starting from the entering end of the roller 6. The radian of the pressing plate gradually increases. After the roller 6 enters the water removal hopper 11, as the roller 6 moves downward, the pressing plate gradually presses the first water suction component 10 and the water suction unit 13. When the roller 6 reaches the bottom of the water removal hopper 11, the pressing force reaches the maximum. Then the roller 6 rotates to continuously change the pressing area, and the accumulated water is continuously discharged into the water tank, thus completing the water removal work for the entire roller.

[0033] In one embodiment, the lifting arm includes a connecting arm 5, a gear set, a rack 9 and a cylinder 7. Both ends of the connecting arm 5 are respectively rotationally connected to the roller 6 and the mobile vehicle body 1. The gear set is fixedly connected to one end of the connecting arm 5 located on the mobile vehicle body 1. The cylinder 7 is fixed on one side of the mobile vehicle body 1, and the extending end of the cylinder 7 points to one side of the roller 6. The rack 9 is fixed on the extending end of the cylinder 7, and the rack 9 meshes with the gear set.

[0034] In this embodiment, the gear set is divided into a fixed gear 8 and a transmission gear 21. The transmission gear 21 is a stepped gear. The small gear of the transmission gear 21 meshes with the rack 9, and the large gear of the transmission gear 21 meshes with the fixed gear 8. In this embodiment, when the cylinder 7 retracts, it drives the rack 9 to move backward, and drives the connecting arm 5 to lift the roller 6 through the transmission gear 21. The roller 6 rotates around the fixed gear 8 and enters the water removal bucket 11. By the meshing of the rack 9 and the gear set to drive the connecting arm 5, the connection is reliable and stable, with stronger load capacity and not prone to fatigue damage.

[0035] In another embodiment, the lifting of the connecting arm 5 can also adopt a scheme of direct drive by a motor or a motor driving a gear set.

[0036] In one embodiment, it further includes a sludge pump 2, a sludge suction port, a sludge pipe 4 and a sludge box 3. The sludge pipe 4 connects the sludge suction port, the sludge pump 2 and the sludge box 3 in sequence. The sludge suction port is located behind the mobile vehicle body 1 and faces downward. In this embodiment, the sludge pump 2 and the sludge box 3 are fixed on the top of the mobile vehicle body 1, which is convenient for cleaning and maintenance. After the first water suction assembly 10 and the water suction unit 13 suck out the accumulated water, the mobile vehicle body 1 moves forward, and the sludge suction port at the rear sucks out the sludge and gravel together, further improving the cleaning efficiency.

[0037] In the above embodiment, preferably, it further includes a sensor for detecting the water content and a central processor. The sensor is respectively installed in the first water suction assembly 10 and the water suction unit 13, and the sensor is connected to the central processor. By the sensor detecting the water content of the first water suction assembly 10 and the water suction unit 13, the central processor judges the water removal mode and the water removal timing according to the water content, improving the automation level of this embodiment.

[0038] In this embodiment, the sensor can adopt a capacitive sensor. Its principle is that the dielectric constant of accumulated water is much higher than that of air. After the first water suction assembly 10 and the water suction unit 13 absorb water, the capacitance value will change significantly. The water removal mode and the water removal timing are judged by comparing the capacitance value with a preset threshold.

[0039] As Figure 5 shown, this embodiment also provides a control method for a tunnel accumulated water cleaning device, which is applied to the water pit water removal mode of the tunnel accumulated water cleaning device as described above, and includes the following steps: S1. Obtain the current accumulated water information on the tunnel ground, and judge whether there is a water pit on the tunnel ground that meets the preset conditions according to the current accumulated water information; the current accumulated water information includes the depth, and the preset condition is whether the depth is greater than the thickness of the first water suction assembly 10. When the depth is greater than the thickness of the first water suction assembly 10, it is determined that there is a water pit, and the water pit water removal mode is switched.

[0040] In one embodiment, the mobile vehicle body 1 is further provided with an image collector connected to the central processor. The image collector collects in real time the accumulated water image of the tunnel ground in front of the moving path of the mobile vehicle body 1. The central processor judges the depth of the accumulated water on the tunnel ground by comparing the gray value of the accumulated water image with a preset gray value. The specific judgment process is prior art and will not be elaborated here.

[0041] S2. When there is a puddle on the tunnel ground that meets the preset conditions, control the roller 6 to move directly above the puddle, and then control the roller 6 to rotate so that the opening corresponds to the puddle. Specifically, when the roller 6 moves directly above the puddle and the opening does not correspond to the puddle, the roller 6 idles until the opening is directly opposite the puddle.

[0042] S3. Control the first driving mechanism to move in a direction away from the rotating shaft 12 according to the current accumulated water information, so as to drive the second water absorption assembly to extend out of the opening. After reaching a preset duration, control the first driving mechanism to move in a direction close to the rotating shaft 12 to retract the second water absorption assembly to the inner side of the opening; specifically, control the movement stroke of the first driving mechanism according to the depth, so as to realize the precise control of the second water absorption assembly.

[0043] S4. Obtain the water content of each water absorption unit 13, and determine the maximum value of the water content in all the water absorption units 13, and judge whether the maximum value reaches the preset water content.

[0044] 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 absorbed, and return to step S1, and the mobile vehicle body 1 continues to move forward.

[0045] S6. When the maximum value reaches the preset water content, control the second water absorption assembly to remove water, and then return to step S3.

[0046] Further, step S3 specifically includes the following steps: S31. Obtain the width of the puddle; judge whether the width of the puddle is greater than the width of one water absorption unit 13.

[0047] S32. When the width of the puddle is greater than the width of one water absorption unit 13, control the roller 6 to move directly above the puddle, and then rotate the roller 6 so that the opening corresponds to the puddle.

[0048] S33. Control the corresponding number of the first driving mechanisms to move in a direction away from the rotating shaft 12 according to the current water accumulation information and the width of the puddle, so as to drive the second water absorption assembly to extend out of the opening. After reaching a preset duration, control the first driving mechanisms to return to retract the second water absorption assembly; wherein, in the second water absorption assembly extending out of the opening, the sum of the widths of the water absorption units 13 matches the width of the puddle.

[0049] Further preferably, in step S33, the controlling the corresponding number of the first driving mechanisms 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 absorption assembly to extend out of the opening is specifically as follows: When the width of the puddle is greater than n times the width of one water absorption unit 13 and less than n + 1 times the width of one water absorption unit 13, control n first driving mechanisms to move in a direction away from the rotating shaft 12 to drive the second water absorption assembly to extend out of the opening; wherein, n is a positive integer and n ≥ 1. For example, when the width of the puddle is 2.5 times the width of the water absorption unit 13, then control 2 first driving mechanisms to move in a direction away from the rotating shaft 12 to drive the second water absorption assembly to extend out of the opening.

[0050] Further, in step S6, the controlling the second water absorption assembly to remove water specifically includes the following steps: S61. Control all the first driving mechanisms to move in a direction close to the rotating shaft 12 so that the second water absorption assembly moves inside the roller 6. Control the rotating shaft 12 to rotate in the opposite direction of the mouth orientation of the water collecting hopper 19 until the water absorption unit 13 is above the mouth of the water collecting hopper 19, and open the sealing cover.

[0051] S62. Control the first driving mechanisms to move in a direction away from the rotating shaft 12 to squeeze the water absorption unit 13 so that the accumulated water remaining in the water absorption unit 13 flows into the water collecting hopper 19.

[0052] S63. Control the first driving mechanisms to move in a direction close to the rotating shaft 12, and control the rotating shaft 12 to reverse so that the second water absorption assembly corresponds to the opening and close the water collecting hopper 19.

[0053] S64. Control the first driving mechanisms to move in a direction away from the rotating shaft 12 so that the second water absorption assembly returns to the opening.

[0054] In another embodiment, a control method for a tunnel water accumulation cleaning device is further provided, which is applied to the tunnel water accumulation cleaning device as described above, and includes the following steps: S1. Obtain the current water accumulation information on the tunnel floor, and determine whether there is a puddle on the tunnel floor that meets the preset conditions according to the current water accumulation information.

[0055] S2a. If it is determined that there is no puddle, control the roller 6 to contact the ground and roll forward, and the first water absorption component 10 and the water absorption unit 13 together absorb the water on the ground.

[0056] S3a. Obtain the water content of the first water absorption component 10 and the water absorption unit 13, and compare the water content of the first water absorption component 10 with the preset water content, and the water content of the water absorption unit 13 with the preset water content to see if either one reaches the preset water content.
