Description

Technical Field

[0001] This utility model patent belongs to the field of borehole drainage technology, specifically relating to a novel drainage device for water-bearing boreholes. Background Technology

[0002] Water-bearing borehole blasting is a recognized production challenge in the blasting industry. Due to the difficulty in controlling the quality of the charge and packing, blasting quality problems such as a high rate of large fragments and frequent ground-level explosions often occur. For water-bearing borehole blasting using pre-mixed emulsion explosives, the following problems often arise (such as...). Figure 1 ):

[0003] (1) After the explosive is put into the hole, it will become stuck in the water due to buoyancy. The explosive may not sink to the bottom or form a loading gap in the middle of the hole, which may lead to the occurrence of blasting at the root or the generation of residual explosive.

[0004] (2) Due to buoyancy, the explosive cartridges in the borehole are in an "overlapping" state, resulting in low charge density, insufficient explosive power, and easy generation of large explosive fragments; the continuity of charge in the borehole is poor, the detonation is unstable, and residual charge is easy to be generated.

[0005] Therefore, existing technologies often use drainage mechanisms to drain water-bearing blast holes. For example, Chinese Patent (CN221173165U) discloses a drainage device for water-bearing blast holes in open-pit mines, which includes a lifting frame and a water collection pipe set below the lifting frame. A floating block is set at the bottom of the water collection pipe, and two sliding rods are fixedly connected to the top of the floating block. A fixing ring is set in the inner cavity of the water collection pipe, and limit rings are welded to both sides of the inner cavity of the fixing ring.

[0006] The inventors discovered the following technical defects in this type of device:

[0007] 1. The device includes a lifting frame and a water collection pipe located below the lifting frame. Its structure is too complicated, making it difficult to assemble, use, and move.

[0008] 2. The device uses a lifting frame to collect, lift, and pour water, which is cumbersome, slow in water intake and drainage, and inconvenient to use in places where a lifting frame cannot be placed. It is subject to terrain limitations when in use.

[0009] Therefore, this paper proposes a novel drainage device for water-bearing boreholes. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figures 1 to 8 As shown, the prior art in this embodiment has the following problems: The inventor found that the prior art Chinese patent (CN221173165U) discloses a drainage device for water-bearing blast holes in open-pit mines, which also has the following technical defects: 1. The device includes a lifting frame and a water collection pipe set below the lifting frame. Its structure is too complicated, and it is troublesome to assemble and use, and it is not easy to transport; 2. The device uses the lifting frame to take water, lift, and pour water. The steps are complicated, the water intake and drainage speed is slow, and it is not convenient to use in places where the lifting frame cannot be placed. There are terrain limitations when using it.

[0035] Therefore, the inventor provides a novel drainage device for water-bearing boreholes, including a pull rope (not shown in the figure) and a water collection assembly. The pull rope is connected to the top of the water collection assembly. The water collection assembly also includes a top cover 5, a water collection sleeve 6, a counterweight 7, a set piston 8, and a handle 9. The top cover 5 and the counterweight 7 are respectively installed on the top and bottom of the water collection sleeve 6. The water collection sleeve 6 is formed by connecting several unit water collection tanks through corresponding internal and external threads 13 at its upper and lower ends. The set piston 8 is formed by connecting several unit pistons through corresponding threaded sleeves 21 at its upper and lower ends to a screw 22, and each unit piston is installed in a corresponding unit water collection tank. The handle 9 is connected to the screw 22 at the top of the set piston 8 through the threaded sleeve 21 at its bottom. The top cover 5 and the water collection sleeve 6 are both provided with rod holes 15 at their centers to accommodate the piston rod 18 of the set piston 8. A sealing structure is provided on the inner wall of the rod hole 15.

[0036] Its effects are as follows: The device has a simple structure, and users can assemble water collection components of appropriate length as needed for use in water-bearing boreholes of different depths. At the same time, the device can quickly draw water by pushing the piston to vent air and quickly drain water by pulling the piston, thereby quickly pumping out the water accumulated in the water-bearing borehole. It is easy to operate, portable, and has no terrain limitations.

[0037] Furthermore, a rope buckle 10 is provided on the top cover 5; this structure makes it easy for users to tighten the pull rope, thereby facilitating the lifting of the water collection component.

[0038] Furthermore, the unit water collection tank also includes a tank body 11, an internal thread 12, an external thread 13, a side hole 14, and a rod hole 15. The inner side of the top of the tank body 11 is provided with an internal thread 12, and the outer side of the bottom of the tank body 11 is provided with an external thread 13 corresponding to the top. Several side holes 14 are evenly provided on the upper side of the tank body 11, and a rod hole 15 is provided at the center of the bottom of the tank body 11. The internal thread 12 and external thread 13 in this structure allow multiple unit water collection tanks to be assembled by connecting them vertically. The number of unit water collection tanks can be selected according to the depth of the water-bearing borehole, so it can be applied to water-bearing boreholes of various depths. The side hole 14 in this structure can be used to cooperate with the up and down movement of the set piston 8 to quickly draw in and drain water.

[0039] Furthermore, a filter screen can be wound around the barrel 11 where the side hole 14 is located; this structure can be used to filter impurities in the water.

[0040] Furthermore, the unit piston also includes a piston seat 16, a rubber sleeve 17, a piston rod 18, an inflation channel 19, an exhaust check valve 20, a screw sleeve 21, a screw 22, and an inflation hole 23. The piston seat 16 is movably installed in the unit water collection tank and a rubber sleeve 17 is installed on its outer side. The piston seat 16 is connected to the piston rod 18 on three sides. The inflation channel 19 is located at the center of the piston seat 16 and the piston rod 18. An exhaust check valve 20 is provided on the piston seat 16 to connect the upper and lower tank bodies 11. The screw sleeve 21 is located at the bottom center of the piston seat 16. The screw 22 is located at the top of the piston rod 18 and is connected to the screw sleeve 21 at the bottom center of the previous piston seat 16. The inflation hole 23 is located on the side of the piston rod 18 below the screw 22 and is connected to the inflation channel 19.

[0041] Before pumping water, the piston seat 16 is pulled to the top of the barrel 11. During the pulling process, the inflation check valve 24 at the top of the handle 9 can inflate the barrel 11 below the piston seat 16 through the inflation channel 19 and inflation hole 23, thus preventing the unit piston from being unable to be pulled down by the air pressure. After reaching the top, the water collection assembly is placed into the water-filled cannon hole for pumping. At this time, the user can push the handle 9 down to press down the unit piston. During this process, the inflation check valve 24 closes and the exhaust check valve 20 opens, thus expelling the gas in the barrel 11 below the piston seat 16 upwards through the side hole 14. At this time, under the action of air pressure, the water around the barrel 11 will be quickly pressed into it, thus achieving rapid pumping. When draining water, the user lifts the water collection assembly and then pulls the handle 9 to pull the piston for rapid drainage. At this time, the inflation check valve 24 opens and the exhaust check valve 20 closes.

[0042] Furthermore, the movement space of the inflation hole 23 in the barrel 11 is located between the piston seat 16 and the rod hole 15, except for the inflation hole 23 on the piston rod 18 at the top of the piston 8; this structure design allows the space of the barrel 11 below the piston seat 16 to be connected with the inflation check valve 24 and the inflation channel 19, thereby reducing the influence of air pressure on the piston when the piston is pulled, enabling it to pull the piston quickly.

[0043] Furthermore, the air inlet 23 on the piston rod 18 at the top of the piston assembly 8 is sealed with tape (not shown in the figure); this structure is designed to prevent the gas in the space of the barrel 11 below the piston seat 16 from being discharged through the air inlet 23 on the piston rod 18 at the top of the piston assembly 8 during exhaust, ensuring that the gas can be discharged through the side hole 14, thereby achieving rapid water pumping.

[0044] Furthermore, an inflation check valve 24 is provided on the top of the handle 9; this structure ensures smooth inflation.

[0045] Furthermore, the sealing structure also includes a rubber groove 25 and a sealing ring 26. The rubber groove 25 is installed on the inner wall of the rod hole 15, and the sealing ring 26 is installed in the rubber groove 25. This structure is designed to ensure that the piston rod 18 can maintain a seal when it moves in the rod hole 15.

[0046] The working principle of this utility model:

[0047] Before pumping water, the piston seat 16 is pulled to the top of the barrel 11. During the pulling process, the inflation check valve 24 at the top of the handle 9 can inflate the barrel 11 below the piston seat 16 through the inflation channel 19 and inflation hole 23, thus preventing the unit piston from being unable to be pulled down by the air pressure. After reaching the top, the water collection assembly is placed into the water-filled cannon hole for pumping. At this time, the user can push the handle 9 down to press down the unit piston. During this process, the inflation check valve 24 closes and the exhaust check valve 20 opens, thus expelling the gas in the barrel 11 below the piston seat 16 upwards through the side hole 14. At this time, under the action of air pressure, the water around the barrel 11 will be quickly pressed into it, thus achieving rapid pumping. When draining water, the user lifts the water collection assembly and then pulls the handle 9 to pull the piston for rapid drainage. At this time, the inflation check valve 24 opens and the exhaust check valve 20 closes.
