Description

Technical Field

[0001] The present invention relates to the technical field of drainage devices, and specifically to a rapid drainage device for water-rich inclined shafts in tunnels. Background Art

[0002] An inclined shaft refers to a passage that is set according to needs in a super-long tunnel, forms a certain included angle with the main tunnel and leads directly to the ground. It is an important entrance and exit for mucking, transporting materials and equipment during the construction of the main tunnel, and is also an important ventilation port during the construction and operation periods of the super-long tunnel and an important passage for emergency rescue.

[0003] When an inclined shaft is being built, there will be a lot of accumulated water inside, so it is necessary to drain the accumulated water in the inclined shaft. Most of the existing drainage devices directly put the water pump into the accumulated water for extraction during use, and it is necessary to dig a sump in the inclined shaft to transfer the accumulated water. As a result, the flowing of the accumulated water below will drive the movement of the water pump, which is likely to cause damage to the water pump and reduce the drainage stability. Digging a sump increases the construction volume and cost, which is not conducive to use. Summary of the Invention

[0025] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0026] Please refer to Figures 1-5, which is a structural diagram of a rapid drainage device for a water-rich inclined shaft in a tunnel provided by an embodiment of the present invention, includes a hoist 1. A first flexible member 2 is wound around the hoist 1. A counterweight 3 is fixedly installed at the movable end of the first flexible member 2. A fixed block 5 is fixedly installed at one end of the first flexible member 2 close to the counterweight 3. The fixed block 5 is connected to a bottom plate 9. A support assembly 29 is arranged on one side surface of the bottom plate 9. A first water pump 13 is fixedly installed on the bottom plate 9. The first water pump 13 is communicated with a water suction pipe 14. A detection pipe 16 is fixedly installed on the bottom plate 9. The detection pipe 16 penetrates through the bottom plate 9 and one end is arranged in an open structure. A first pressure sensor 17 is fixedly installed in the detection pipe 16. An elastic member 19 is fixedly installed on the surface of the first pressure sensor 17. One end of the elastic member 19 far from the first pressure sensor 17 is fixedly installed with a floating plate 18 slidably installed in the detection pipe 16. A movable plate 20 is detachably connected to the first flexible member 2. A water tank 21 is fixedly installed on one side surface of the movable plate 20. A second pressure sensor 22 is fixedly installed on one side in the water tank 21. The water tank 21 is communicated with the first water pump 13 through a first water pipe 24. A second water pump 23 is fixedly installed on the water tank 21. The second water pump 23 is communicated with a second water pipe 25.

[0027] A plurality of groups of rollers 4 are rotatably installed on one side surface of the counterweight 3 at intervals.

[0028] A protective cover 15 distributed around the water suction pipe 14 is fixedly installed on the bottom plate 9.

[0029] A second flexible member 6 is fixedly connected to the fixed block 5. One end of the second flexible member 6 far from the fixed block 5 is fixedly connected to a hook 7. The hook 7 is used in cooperation with a hanging ring 8 fixedly installed on the bottom plate 9.

[0030] In practical applications of the embodiments of the present invention, the hoist 1 is fixed at the entrance of the inclined shaft, the counterweight 3 is placed in the inclined shaft, the bottom plate 9 is connected to the fixed block 5, and the state of the support assembly 29 is adjusted according to the inclination degree of the inclined shaft, so that while the support assembly 29 is in smooth contact with the inclined shaft, the bottom plate 9 can be in a horizontal state. Then, the hoist 1 releases the first flexible member 2, and under the action of gravity, the counterweight 3 and the bottom plate 9 quickly descend along the inclined shaft. Under the action of the counterweight 3, the first flexible member 2 is in a tensioned state, improving the stability when subsequent components descend. After the bottom plate 9 descends to the limit distance of the lift of the first water pump 13, the first water pipe 24 is communicated with the water tank 21, then the moving plate 20 is fixedly connected to the first flexible member 2, and then the moving plate 20 is made to follow the first flexible member 2 into the inclined shaft. Subsequently, an appropriate number of moving plates 20 can be added according to the depth of the inclined shaft. When the bottom plate 9 moves downward to contact the water surface, the water surface will push the floating plate 18 upward and compress the elastic member 19. Thus, the first pressure sensor 17 detects that the pressure reaches the set first threshold value. At this time, the hoist 1 stops releasing the first flexible member 2. At this time, the water in the inclined shaft is pumped out by the first water pump 13 and the water suction pipe 14. The first water pump 13 transports the water to the water tank 21 through the first water pipe 24. When the second pressure sensor 22 in the water tank 21 reaches the set threshold value, the second water pump 23 is started to continue transporting the water in the water tank 21 upward. When the detected value of the second pressure sensor 22 is less than the threshold value, it indicates that there is less water in the water tank 21. At this time, the second water pump 23 is stopped to avoid the second water pump 23 idling, thereby reducing energy consumption. After the water in the inclined shaft is discharged outward, the water surface drops. At this time, the floating plate 18 moves downward, so that the pressure detected by the first pressure sensor 17 drops. When the pressure drops to the set second threshold value, the hoist 1 continues to release the first flexible member 2 to make the bottom plate 9 continue to descend, so that the bottom plate 9 moves downward following the water surface, ensuring that the water suction pipe 14 always remains below the water surface and realizing rapid and continuous drainage. When the water in the inclined shaft increases, the water surface rises and pushes the floating plate 18 upward. At this time, the pressure detected by the first pressure sensor 17 exceeds the set first threshold value. Thus, the hoist 1 winds up the first flexible member 2 to make the bottom plate 9 move upward until it exposes above the water surface, ensuring that the accumulated water in the inclined shaft can always be pumped from the water surface, avoiding the influence on the first water pump 13 caused by the flowing of the accumulated water, and ensuring the stability of the extraction and discharge of the accumulated water. The accumulated water is transferred through the moving water tank 21, avoiding digging a sump in the inclined shaft, reducing the construction volume, and improving the inventiveness and flexibility of use, increasing the speed and efficiency of drainage, and being beneficial to use.

[0031] In an example of the present invention, the first flexible member 2 is a wire rope. Of course, it can also be a flexible member made of other materials. By arranging a drainage member below the wire rope, the stability is improved. The second flexible member 6 is a guy wire, and the bottom plate 9 is connected through the guy wire to reduce the influence of factors on the fixed block 5 on the bottom plate 9. The elastic member 19 is a spring. Of course, it can also be other elastic members such as elastic balls. The spring deforms to apply pressure to the first pressure sensor 17.

[0032] As Figure 1 , Figure 3 shown, as a preferred embodiment of the present invention, a plurality of sets of rollers 4 are also rotatably installed on the surface of the moving plate 20 away from the water tank 21 at intervals. A connecting plate 26 is fixedly installed in the middle of the surface of the moving plate 20 away from the water tank 21. One end of the connecting plate 26 away from the moving plate 20 is detachably connected with a connecting block 27.

[0033] Semicircular grooves for cooperating with the first flexible member 2 are provided on both the connecting plate 26 and the connecting block 27. A plurality of second fixing screws 28 for threadedly connecting with the connecting plate 26 are provided on the connecting block 27.

[0034] In actual application of the embodiment of the present invention, the connecting block 27 is removed, and then the first flexible member 2 is placed in the groove between the connecting plate 26 and the connecting block 27. Then, the connecting block 27 is fixed on the connecting plate 26 through the second fixing screw 28 and the first flexible member 2 is pressed tightly, so that the moving plate 20 is fixed on the first flexible member 2. The distance between the moving plate 20 and the fixed block 5 is controlled according to the lift of the first water pump 13. According to the depth of the inclined shaft, multiple moving plates 20 can be conveniently added to ensure rapid drainage.

[0035] As Figures 1-3 shown, as a preferred embodiment of the present invention, the first pressure sensor 17 is electrically connected to the winch 1 through the first control module, and the second pressure sensor 22 is electrically connected to the second water pump 23 through the second control module.

[0036] In actual application of the embodiment of the present invention, the winch 1 is controlled to wind or release the first flexible member 2 according to the pressure change of the first pressure sensor 17. When the pressure of the first pressure sensor 17 increases to the set threshold value, it indicates that the water level rises at this time. At this time, the winch 1 winds the first flexible member 2. Otherwise, the first flexible member 2 is released. The second pressure sensor 22 detects the water content in the water tank 21. When the second pressure sensor 22 reaches the set threshold value, it indicates that there is still more water in the water tank 21 at this time. At this time, the second water pump 23 is turned on to drain the water in the water tank 21. When the reading of the second pressure sensor 22 is less than the threshold value, the second water pump 23 stops working.

[0037] As Figure 1 , Figure 2 , Figure 5As shown, as a preferred embodiment of the present invention, the support assembly 29 includes a telescopic member 10. There are multiple groups of telescopic members 10, and the telescopic members 10 are fixedly installed on the bottom plate 9. One end of the telescopic member 10 away from the bottom plate 9 is fixedly installed with a mounting plate 11. Rollers 4 are also rotatably installed on the surface of the mounting plate 11 away from the telescopic member 10 and are spaced apart.

[0038] A first fixing screw 12 for fixing the length of the telescopic member is threadedly connected to the telescopic member 10.

[0039] When the embodiment of the present invention is actually applied, the lengths of the telescopic members 10 on both sides are adjusted according to the inclination degree of the inclined shaft, so that when the rollers 4 contact the bottom surface of the inclined shaft, the bottom plate 9 is in a horizontal state at this time. After the adjustment is completed, the length of the telescopic member 10 is fixed by the first fixing screw 12, so as to contact the inclined shaft through the rollers 4, reduce the friction force, and improve the smoothness of movement.

[0040] In an example of the present invention, the telescopic member 10 is a telescopic rod. Of course, it can also be a plate member that slides through the bottom plate 9. The telescopic rod drives the mounting plate 11 to move up and down, so as to adjust the bottom plate 9 to be in a horizontal state.

[0041] The above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of this patent.
