Description

Technical Field

[0001] This utility model relates to a diversion device for drilling holes for water exploration and drainage in mines, belonging to the technical field of diversion equipment for drilling holes for water exploration and drainage in mines. Background Technology

[0002] In the past, a common method to prevent water inrush in mines was to pre-construct a borehole fixing operation. The installation and fixing of borehole casings in underground mines typically involved drilling a hole, inserting a casing, and then fixing it with cement. However, this operation must be carried out at the initial stage of drilling. If this equipment is not available initially, this method is unlikely to succeed in the event of unforeseen circumstances later. Alternatively, the original drill rod can be directly inserted into the hole to block the water; this method is feasible but expensive. In surface foundation pit operations, pipe insertion for drainage is a common practice. Application CN202020706924.4 discloses a drainage device for underground water exploration and drainage boreholes in mines, comprising a casing, a water-stop rubber strip, a conical rubber pad, a steel plate, a hose with a fire-fighting water connector, and ground anchor reinforcement. The conical rubber pad is fitted onto the outer side of the casing's tail end, and the tail end is threadedly connected to the fire-fighting water connector on the hose. Other exposed parts of the casing's outer side are wrapped with a water-stop rubber strip. A pre-drilled hole is provided in the middle of the steel plate, which is engaged with the fire-fighting water connector. One end of the steel plate is fixedly connected to the ground anchor reinforcement. This utility model is a plug-and-play rapid drainage device, mainly used to solve the problem of sudden water inrush in underground boreholes; it drains water, creates a dry environment, quickly controls the situation from worsening, and prepares for the next stage of construction.

[0003] However, the device still has the following problems: the length of the ground anchor steel bar needs to be set in advance according to different installation locations before installation. The length of the ground anchor steel bar required in different locations is different. Therefore, the actual use and installation are more complicated and inconvenient.

[0004] Therefore, this utility model proposes a new solution. Utility Model Content

[0005] The main purpose of this utility model is to provide a drainage device for drilling holes for water exploration and drainage in mines, in order to overcome the shortcomings of the existing technology.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A drainage device for drilling water exploration holes in mines includes a drainage pipe, an expansion pipe connected to the outer wall of one end of the drainage pipe, a compression pipe threaded to the outer wall of the drainage pipe and a sealing element connected to the outer wall of the compression pipe, a valve installed at the end of the drainage pipe away from the expansion pipe, and a connecting pipe connected to one end of the valve.

[0008] Preferably, two symmetrical handles are fixedly connected to the outer wall of the extrusion tube.

[0009] Preferably, the handle has a mounting hole, and a ground nail is installed on the inside of the mounting hole.

[0014] Preferably, a metal ring plate is fixedly connected to one end of the expansion tube near the extrusion tube.

[0015] Preferably, the expansion tube is a rubber expansion tube, which includes a fixed section fixedly connected to the outer wall of the drainage tube, a movable section above the fixed section, and an expansion section connecting the movable section and the fixed section.

[0016] Preferably, a fixing plate is fixedly connected to the bottom outer wall of the drainage tube, and the fixing section is connected to the top of the fixing plate.

[0017] The beneficial technical effects of this utility model are as follows: The drainage device for underground water exploration and drainage drilling in mines according to this utility model:

[0018] 1. With the setup of drainage tube, expansion tube and squeezing tube, when in use, insert this device into the borehole, and then control the relative rotation of the drainage tube and squeezing tube to compress the expansion tube, so that the middle part of the expansion tube bulges outward and squeezes against the inner wall of the borehole, and fixes the device by friction.

[0029] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0030] like Figures 1-6As shown in the figure, the drainage device for underground water exploration and drainage drilling in mines provided in this embodiment includes a drainage pipe 1, an expansion pipe 2 connected to the outer wall of one end of the drainage pipe 1, a compression pipe 3 threadedly connected to the outer wall of the drainage pipe 1 and a sealing member 4 connected to the outer wall of the compression pipe 3, a valve 5 installed at the end of the drainage pipe 1 away from the expansion pipe 2, and a connecting pipe 6 connected to one end of the valve 5. With the arrangement of the drainage pipe 1, expansion pipe 2, and compression pipe 3, the device is inserted into the borehole during use. Then, the drainage pipe 1 and compression pipe 3 are rotated relative to each other, compressing the expansion pipe 2. This causes the middle part of the expansion pipe 2 to bulge outward and press against the inner wall of the borehole, fixing the device in place by friction. This method is suitable for drainage in boreholes at different locations. Because the expansion pipe 2 is pressed against the inner wall of the borehole, it can seal the space between the drainage pipe 1 and the borehole, allowing water to flow out only through the drainage pipe 1, thus enabling water drainage. With the valve 5 and connecting pipe 6, a water supply pipe is connected to the outside of the device during use, and the flow rate is controlled by the valve 5. The sealing element 4, in conjunction with the expansion pipe 2, provides a double-layer seal, preventing water from flowing out through the gap between the drainage pipe 1 and the borehole.

[0031] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, two symmetrical handles 7 are fixedly connected to the outer wall of the extrusion tube 3. Each handle 7 has a mounting hole 8, and a ground nail 9 is installed inside the mounting hole 8. A rotating ring 10 is connected to the end of the drainage tube 1 furthest from the expansion tube 2. With the handles 7 and the rotating ring 10 in place, when extruding the expansion tube 2, two people can rotate the handles 7 and the rotating ring 10 respectively to rotate the drainage tube 1 and the extrusion tube 3 relative to each other, thus compressing the expansion tube 2. Alternatively, the handles 7 can be fixed to the outer wall of the borehole opening using the ground nail 9, and then the rotating ring 10 can be rotated to rotate the drainage tube 1 and the extrusion tube 3 relative to each other, thus compressing the expansion tube 2.

[0032] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, a screw hole 11 is provided on the outer wall of the extrusion tube 3, and a screw 12 is installed on the inner side of the screw hole 11. Several limiting grooves 13 are provided on the outer wall of the drainage tube 1 along the circumferential direction. With the setting of screw hole 11, screw 12 and limiting grooves 13, after compressing the expansion tube 2, tightening the screw 12 can prevent the drainage tube 1 and the extrusion tube 3 from reversing relative to each other. It should be noted that the expansion tube 2 can generate a large margin when compressed, so that the screw 12 can enter the limiting groove 13.

[0033] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the sealing component 4 includes several stepped rubber discs 14, the diameter of which decreases from top to bottom. The rubber discs 14, in conjunction with the expansion tube 2, provide a double-layer seal, preventing water from flowing out through the gap between the drainage tube 1 and the borehole.

[0034] In this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, a metal ring plate 15 is fixedly connected to one end of the expansion tube 2 near the extrusion tube 3. The metal ring plate 15 prevents the extrusion tube 3 from directly contacting the expansion tube 2 and causing wear on the expansion tube 2, while also reducing friction during rotation.

[0035] In this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, the expansion tube 2 is a rubber expansion tube. The expansion tube 2 includes a fixed section 201 fixedly connected to the outer wall of the drainage tube 1. A movable section 202 is provided above the fixed section 201. An expansion section 203 is connected between the movable section 202 and the fixed section 201. A fixing plate 16 is fixedly connected to the bottom outer wall of the drainage tube 1, and the fixed section 201 is connected to the top of the fixing plate 16. The expansion tube 2 includes a fixed section 201, a movable section 202, and an expansion section 203. When the drainage tube 1 and the extrusion tube 3 rotate relative to each other and extrude the expansion tube 2, the movable section 202 will be extruded and moved toward the fixed section 201, thereby causing the expansion section 203 to protrude and fit against the inner wall of the borehole.

[0036] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the drainage device for underground water exploration and drainage boreholes provided in this embodiment is as follows:

[0037] Step 1: First, connect the external water supply pipe to the connecting pipe 6;

[0038] Step 2: Insert the device into the borehole so that the handle 7 is against the wall. Use the ground nail 9 to fix the extrusion tube 3. Then rotate the rotating ring 10 so that the drainage tube 1 and the extrusion tube 3 rotate relative to each other, compressing the expansion tube 2. This causes the expansion section 203 in the middle of the expansion tube 2 to bulge outward and press against the inner wall of the borehole.

[0039] Step 3: Open valve 5 to drain water.
