Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tunnel flushing, and particularly relates to an adjustable flushing device. BACKGROUND

[0002] A tunnel is a closed space, and dust is easy to accumulate in the tunnel. Part of the dust in the tunnel is caused by the emission of a transportation tool, and another part is caused by the "chimney convection effect" of the tunnel and the air "piston effect" caused by the transportation tool entering and leaving the tunnel. The dust is sucked into the tunnel, which causes the dust to be sucked into the tunnel. If the dust is not cleaned in time, it will have a destructive effect on various facilities in the tunnel.

[0003] Chinese invention patent 2019108419266 discloses a rail type automatic flushing device for a deep tunnel, which comprises a water tank, a flushing main pipe, a flushing hose, an automatic telescopic pipe reel, a rail and a moving mechanism. The flushing main pipe is connected with the water tank. The flushing hose is wound on the automatic telescopic pipe reel, and one end of the flushing hose is connected with the flushing main pipe, and the other end is connected with a water spraying mechanism. The rail is arranged in the deep tunnel, and the moving mechanism is arranged on the rail. The water spraying mechanism is fixedly arranged on the moving mechanism. The flushing device has poor adjustment effect and low adjustment efficiency.

[0004] Chinese invention patent 2011101405139 discloses a passive self-pressurized mobile flushing device for a coal mine underground rail lane, which comprises a water storage tank and an air compressor fixed on a board car. The air compressor is connected with the water storage tank through a board car wheel shaft belt mechanism. The water storage tank is connected with a medicament tank, a hand pump and a back pressure valve. The other end of the hand pump is connected with the medicament tank. The other end of the back pressure valve is connected with a water spraying pipe. The flushing device has poor flushing effect and low flushing efficiency.

[0005] The existing flushing device has the following problems. When the device is used, the spray head is fixedly installed, so the angle of the spray head cannot be adjusted during spraying, resulting in a small flushing range, and the device has great limitations during use, and the flushing efficiency is reduced.

[0006] When the liquid level in the water distribution tank continuously decreases, the centrifugal force received by the water in the water distribution tank is different due to the difference in the weight of the water, and the distance of the water sprayed from the water distribution tank is different, thereby easily reducing the flushing effect on the dust and other objects in the tunnel.

[0007] When the liquid level in the water distribution tank changes, the shaking of the vehicle body causes the change of the impact force of the water in the water distribution tank on the inner wall, which affects the normal work of the water distribution tank, and further drives the alarm response of the alarm triggering unit in advance, thereby reducing the alarm accuracy of the device.

Therefore, when the electric push rod 76 is activated, it drives the drive rod 12 to move away from the central shaft 75, increasing the distance between the drive rod 12 and the central shaft 75. When the drive circular plate 10 rotates, the rotation diameter of the drive rod 12 increases through the central shaft 75 and the electric push rod 76.

[0045] The other end of the driving rod 12 is connected to a torque-driven rotating shaft 17. The driving rod 12 is connected to a torque-driven square groove 14 on the torque-driven block 13.

The auxiliary spring 44 is in a buffering and resetting state. When the driving block 13 drives the driving rack 15 to move forward, the driving rack 15 drives the two driving gears 16 to rotate, and the driving shaft 17 rotates. The two rotating blocks 18 on the driving shaft 17 move in the rotating rod 68, and the rotating spring 69 is in a buffering state. When the driving block 13 drives the driving rack 15 to move forward, the rotating spring 69 is reset, and the rotating block 18 is reset to the initial position, thereby improving the stability of the driving shaft 17.

[0050] The double-acting stop mechanism includes the extension gear 50 connected with the extension rack 40, the driving threaded shaft 51 provided on the extension gear 50, the driving base 52 fixedly provided on the extension side plate 47, and the double-acting side plate 53 fixedly connected with the driving base 52 at both ends of the driving threaded shaft 51; the double-acting side plate 54 is symmetrically provided on the driving threaded shaft 51, the positioning block 55 is provided on the double-acting side plate 54, the positioning block 55 and the positioning rod 56 are slidably connected, one end of the positioning rod 56 is fixedly connected with the positioning circular plate 57, the other end of the positioning rod 56 is fixedly connected with the driving base 52; the positioning spring 58 is sleeved on the positioning rod 56, one end of the positioning spring 58 is fixedly connected with the driving base 52, and the other end of the positioning spring 58 is fixedly connected with the positioning block 55; the connecting rod 59 is provided on the double-acting side plate 54, the brake side plate 60 is fixedly connected with the connecting rod 59, the brake rod 61 is provided on the brake side plate 60, one end of the brake rod 61 is fixedly connected with the brake circular plate 62, the other end of the brake rod 61 is fixedly connected with the touch side plate 63, and the brake side plate 60 and the touch side plate 63 are connected through the responsive touch unit; the brake spring 64 is sleeved on the brake rod 61, one end of the brake spring 64 is fixedly connected with the brake circular plate 62, and the other end of the brake spring 64 is fixedly connected with the brake side plate 60; the touch side plate 63 is connected with the abutting inclined block 74 fixedly provided on the water distribution tank 65.

The two ends of the driving threaded shaft 51 are threaded, so that the two double extension side plates 54 connected by threads move in the same direction, and are limited by the positioning block 55 in the positioning rod 56, so that the positioning spring 58 is in a buffering state. The connecting rod 59 drives the brake side plate 60 to move, so that the two brake side plates 60 move in the same direction. When the water distribution tank 65 rotates from the initial state, one of the trigger side plates 63 slowly moves away from the contact inclined block 74 on the water distribution tank 65, and the other brake side plate 60 moves towards the rotating water distribution tank 65, and then the other contact inclined block 74 contacts the other trigger side plate 63. When the water distribution tank 65 rotates back, the above operation is repeated to return to the original initial position, so that one of the trigger side plates 63 limits the rotation of the water distribution tank 65, avoiding the driving disc 10 on the rotating and variable assembly moving too far, which causes the water distribution tank 67 to rotate too much and waste water resources. When the water distribution tank 65 rotates to the maximum position and moves back, the water in the water distribution tank 65 has an inertial effect, which produces an impact force and causes vibration. The buffer provided by the brake rod 61 and the brake spring 64 offsets the impact force, avoiding the vibration of the water distribution tank 65, improving the stability of the water distribution tank 67 when spraying, and improving the efficiency of the flushing.

The contact between the two is connected with an alarm unit provided in the plc control panel.

[0053] When the rotating and variable assembly moves too far due to long-term operation, the rotating range of the rotating shaft 17 is expanded, which affects the efficiency of the flushing. When the trigger eccentric rod 70 on the trigger side plate 63 enters the trigger sleeve 71, the moving contact piece 72 and the static contact piece 73 are in contact, which sends a signal to the alarm unit in the plc control panel. The alarm unit sends an alarm to remind the operator, and automatically sends an interrupt signal to the driving motor 8 through the plc control panel, so that the driving motor 8 stops working to avoid wasting water resources.

[0054] At the same time, the touch plate 63 and the touch inclined block 74 are provided with sensors, and when the spray head 67 is driven to rotate to a distance, the two sensors are in contact, so that one of the two record modules in the PLC control board originally displays 0 and jumps to 1, and when the spray head 67 is rotated to reset, the sensor provided on the touch plate 63 and the touch inclined block 74 is in contact, so that the other record module also displays 1, and when the detection module in the PLC control board detects that the two record modules are both 1, the counting module starts from 0 and accumulates +1, and the two record modules are reset to 0; since the water sprayed each time is the same, the number of times the water tank 3 can spray is the same, and the value in the counting module is subtracted by the display module to display in real time in the train body 2, so as to avoid the influence of insufficient water on the flushing efficiency in the middle of flushing.

[0055] Second embodiment

[0056] Based on the first embodiment, when the water in the water tank 65 is continuously sprayed out along the pipeline 66 and the spray head 67, the water level in the water tank 65 continuously decreases, and when the water tank 65 rotates with the rotating shaft 17, the water in the water tank 65 is subjected to different centrifugal forces due to its own gravity, so that the water in the water tank 65 is sprayed out at different distances along the spray head 67, and the flushing effect on the dust and other objects in the tunnel is reduced; at this time, if the rotation angle of the water tank 65 is adjusted, the limiting and stabilizing effect of the water tank 65 by the linkage stabilizing unit and the double-limiting stop mechanism is enhanced, but since the water level in the water tank 65 decreases, the impact force of the water in the water tank 65 on the inner wall when the train body 2 shakes is reduced, which further reduces the normal working effect of the water tank 65 by the linkage stabilizing unit and the double-limiting stop mechanism, and at the same time, the increase of the rotation angle of the water tank 65 also drives the linkage alarm unit to respond to the alarm in advance, which further reduces the alarm accuracy of the device.

[0057] In order to solve the above problems, in actual use, the subsequent use is carried out according to the above process, that is, when the water in the water distribution tank 65 is continuously discharged along the pipeline 66 and the distribution spray head 67 and the dust and other objects in the tunnel are washed in advance, the liquid level value detected by the liquid level sensor decreases, indicating that the amount of water in the water distribution tank 65 decreases at this time. The driving motor 8 is started and the driving block 9 on the output end drives the driving disc 10 to rotate. At this time, the electric push rod 76 is started and elongated, so that the driving disc 10 rotates to increase the rotating diameter of the driving disc 12 through the central shaft 75 and the electric push rod 76. The driving disc 12 moves in the square slot 14 to increase the moving distance, so that the square block 13 drives the square rack 15 to move forward to increase the moving distance, so that the two square gears 16 are engaged to rotate, and the rotating angle of the square shaft 17 is increased, and the rotating angle of the distribution spray head 67 on the square shaft 17 is increased. Further improve the distance of water sprayed along the distribution spray head 67, avoid the decrease of the spray range due to the gravity of the water distribution tank 65 when the liquid level in the water distribution tank 65 decreases, and finally reduce the washing effect of the dust and other objects in the tunnel in advance.

[0058] At the same time, the rotating block 18 moves to drive the fixed seat 19 to move, and through the rope 20 and the fixed pulley 21, the take-up reel 22 is driven to rotate, so that the coupling bevel gear 28 on the coupling shaft 26 is driven to rotate, so that the matching bevel gear 29 is engaged to rotate, so that the matching gear 32 on the matching shaft 30 is driven to rotate, and the two matching racks 33 are engaged to move, so that they are limited to move in the auxiliary base 36 through the matching rod 35, so that the two matching springs 37 are in a buffering state. The two extension square plates 39 move towards each other through the hydraulic splice rod 38, and the force of the extension square plate 47 contacting the water distribution tank 65 is increased through the extension square plate 39 moving towards each other. However, at this time, due to the decrease of the liquid level in the water distribution tank 65, when the water distribution tank 65 shakes with the train body 2, the impact force of the water in the water distribution tank 65 on the inner wall of the water distribution tank 65 decreases, and the impact force of the extension square plate 47 on the water distribution tank 65 is still the original value, which will cause the impact force of the extension square plate 47 on the inner wall of the water distribution tank 65 to be too large, thereby reducing the stability and safety of the water distribution tank 65.

[0059] Therefore, the hydraulic splice rod 38 is started and elongated, and the other end of the extension square plate 39 is moved away from the water distribution tank 65. When the hydraulic splice rod 38 drives the extension square plate 39 to move towards the water distribution tank 65, the extension square plate 47 contacts the side wall of the water distribution tank 65 to a smaller extent, thereby reducing the impact and collision force of the extension square plate 47 on the outer wall of the water distribution tank 65 when the liquid level in the water distribution tank 65 decreases. While ensuring that the limiting vibration effect of the extension square plate 47 on the water distribution tank 65 meets the demand, the safety and stability of the entire device are improved.

[0060] When the extension side plate 39 moves forward, the distance of the extension rack 40 moving is reduced, the rotating angle of the engaged extension gear 50 is reduced, the driving threaded shaft 51 rotates, the two ends of the driving threaded shaft 51 are threaded, the two double extension side plates 54 connected by threads move in the same direction, the double extension side plates 54 are limited to move in the positioning rod 56 through the positioning block 55, the positioning spring 58 is in a buffering state, the brake side plate 60 is moved through the connecting rod 59, the two brake side plates 60 move in the same direction and the distance is reduced, the brake side plate 60 moves towards the rotating water distribution tank 65, and the distance is reduced, and then the water distribution tank 65 moves the touching inclined block 74 to the touching side plate 63, the distance is increased, the touching inclined block 74 and the touching side plate 63 are in stable contact with each other, the extrusion force of the touching side plate 63 on the touching inclined block 74 is in a stable value, and the extrusion force of the touching inclined block 74 on the touching side plate 63 is too large due to the too large rotating angle of the water distribution tank 65, so that the rotating resistance of the water distribution tank 65 is too large and damage occurs.

[0061] At the same time, when the touching side plate 63 is extruded by the touching inclined block 74 to move towards the end of the brake side plate 60, the touching side plate 63 moves the top touching inclined block 74 along the touching sleeve 71, and the distance is equal, the moving contact piece 72 and the static contact piece 73 do not contact, the alarm of the alarm contact unit does not occur, and the whole device is in a stable working state.

[0062] When the water in the water distribution tank 65 is drained, the water in the water distribution tank 65 is continuously raised, the liquid level value detected by the liquid level sensor is continuously increased, the driving round rod 12 is moved towards the end of the central shaft 75, the rotating diameter of the driving round rod 12 is reduced and restored to the original value, the hydraulic rod 38 is reversely started and shortened to the original value, and the above process is repeated to continue to wash the dust and other objects in the tunnel.

[0063] The device has strong adaptability and high stability, can automatically adjust the extension length of the electric push rod 76 and the hydraulic rod 38 according to the water level in the water distribution tank 65, can ensure the washing effect of the dust and other objects in the tunnel, can ensure the contact and collision effect of the touching side plate 47 on the water distribution tank 65, can avoid the reduction of the stability effect due to the change of the water level in the water distribution tank 65, can correspondingly adjust the contact stability effect of the touching inclined block 74 and the touching side plate 63, and can improve the stability and alarm accuracy of the water distribution tank 65.
