Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to an open-air blasting blasthole drainage device. Background Art

[0002] In open-pit mining, large-scale earthwork projects and construction, blasting operations are a common and critical technical link. Traditional blasting methods often require filling explosives into pre-drilled blastholes and detonating them to achieve the purpose of breaking rocks. However, in actual operations, due to natural precipitation, groundwater infiltration or water accumulation during the drilling process, water accumulation to varying degrees often occurs in the blastholes. If this accumulated water is not removed in a timely and effective manner, it will have a significant negative impact on the blasting effect. Therefore, it is necessary to use a blasthole drainage device to drain the water in the blasthole.

[0003] In the prior art, when a traditional drainage device is used, since the blasthole is generally deep, in order to ensure that the pumping pipe can be inserted into the blasthole, it is necessary to use a telescopic rod to extend one end of the drainage pipe into the blasthole. However, when installing the drainage pipe and the telescopic rod, the drainage pipe is usually installed directly between the support plate at the bottom end of the telescopic rod with the help of bolts to facilitate pumping water from the blasthole. Although installation by bolts can improve the stability of the installation, it requires the operator to use additional tools, which is inconvenient for the operator to use and affects the use effect of the drainage device.

[0004] Therefore, there is a need for an open-air blasting hole drainage device to solve the problem that the existing drainage device requires operators to use tools when disassembling and assembling the drainage pipe, which is inconvenient for operators to use. Utility Model Content

[0027] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1 to 11 The utility model provides a technical solution: a drainage device for an open-air blasting hole, comprising a drainage device body 1, a telescopic rod 2, a drainage pipe 3 and a filter plate 5. The drainage pipe 3 is made of a hose as a whole, and the bottom end is a connecting hard pipe, which is convenient for plugging and installing with the filter plate 5. A support plate 4 is installed at the bottom end of the telescopic rod 2, and a slide groove 6 is opened on the right side of the inside of the support plate 4. A rubber plate 16 is installed on the inner wall of the slide groove 6; the left side of the rubber plate 16 fits with the drainage pipe 3, so that the rubber plate 16 increases the friction between the drainage pipe 3 and the support plate 4, thereby improving the stability of its installation and facilitating disassembly and assembly. The bottom end of the drainage pipe 3 passes through the right side of the support plate 4 and is plugged into the filter plate 5.

[0029] First, pass the drain pipe 3 through the right side of the support plate 4, and at the same time, keep the filter plate 5 installed with the support plate 4 using two plug posts 12, so as to drive the bottom end of the drain pipe 3 to be inserted into the top of the filter plate 5, and then drive the rubber plate 16 to slide to the left along the inner wall of the slide groove 6, and then drive the rubber plate 16 to clamp the drain pipe 3. When disassembly is required, drive the rubber plate 16 to move to the right along the inner wall of the slide groove 6 and shrink, so as to facilitate the disassembly of the drain pipe 3, and then the operator can disassemble and assemble the drain pipe 3 without the help of additional tools, thereby improving the use effect of the drainage device body 1.

[0030] Example 2: On the basis of Example 1, in order to drive the rubber plate 16 to clamp the drain pipe 3 and increase the stability of its installation, the right side of the support plate 4 is threadedly connected with a threaded rod 7, and two connecting blocks 17 are installed on the front and rear sides of the rubber plate 16. Two auxiliary grooves 15 are provided on the front and rear sides of the inner wall of the slide 6; the left end of the threaded rod 7 passes through the right side of the slide 6 and is rotatably connected to the rubber plate 16, and the front and rear connecting blocks 17 are both slidably connected to the inside of the auxiliary groove 15, so that by rotating the threaded rod 7, the rubber plate 16 is driven to move to the left along the inner wall of the slide 6 and fit against one side of the drain pipe 3, thereby clamping it and facilitating subsequent disassembly.

[0031] First, pass the drain pipe 3 through the right side of the support plate 4, then rotate the threaded rod 7 to drive the rubber plate 16 to slide to the left along the inner wall of the slide groove 6, and drive the connecting blocks 17 on the front and rear sides to slide along the inner wall of the auxiliary groove 15, thereby driving the rubber plate 16 to clamp the drain pipe 3. Since the rubber plate 16 is squeezed and pushed when moving to the left, it is in a deformed state, thereby increasing the friction between the drain pipe 3 and the support plate 4 and improving the stability of its installation. When disassembly is required, reverse the threaded rod 7 to drive the rubber plate 16 to move to the right along the inner wall of the slide groove 6 and shrink, thereby facilitating the disassembly of the drain pipe 3, and the drain pipe 3 can be disassembled and assembled without the operator having to use additional tools.

[0032] Embodiment 3: On the basis of embodiment 2, in order to realize the disassembly of the drain pipe 3 and the disassembly and cleaning of the filter plate 5 at the same time, movable grooves 8 are provided on the front and rear sides of the support plate 4, and a plug-in block 10 is installed on the inner wall of the movable groove 8. An elastic member 9 is installed on the right side of the plug-in block 10. Connecting ropes 11 are plugged into the front and rear sides of the interior of the support plate 4. Mounting grooves 13 are provided on the front and rear sides of the bottom of the support plate 4. A plug-in column 12 is plugged into the inner wall of the mounting groove 13. A slot 14 is provided on the right side of the plug-in column 12. The left end of the plug-in block 10 passes through the mounting groove 13 and is plugged into the inner wall of the slot 14. The right end of the elastic member 9 is installed on the inner wall of the movable groove 8, and the elastic member 9 is provided with a screw thread 11. It is placed on the outside of the connecting rope 11, so that the elastic force of the elastic member 9 is used to drive the plug-in block 10 to slide to the left along the inner wall of the movable groove 8, and then its left side is inserted into the inner wall of the slot 14, so as to clamp the plug-in column 12 and the support plate 4; one end of the connecting rope 11 is installed between the plug-in block 10, and the other end is installed between the right side of the rubber plate 16, so that when the threaded rod 7 is reversed to drive the rubber plate 16 to slide to the right, the connecting rope 11 is pulled to the right, and the left side of the plug-in block 10 is synchronously driven to disengage from the slot 14, thereby facilitating the removal of the filter plate 5, and the bottom ends of the front and rear columns 12 are installed between the top of the filter plate 5, so as to facilitate the disassembly and assembly of the filter plate 5.

[0033] When the drain pipe 3 is disassembled, the rubber plate 16 contracts to the right along the inner wall of the slide groove 6, thereby pulling the connecting ropes 11 on the front and rear sides to move to the right, thereby driving the plug-in block 10 to slide along the inner wall of the movable groove 8 and squeezing the elastic member 9, so that it is compressed on the inner wall of the movable groove 8. At this time, the left side of the plug-in block 10 is disengaged from the slot 14, making it convenient to pull the two plug posts 12 downward and disengage from the installation groove 13, thereby facilitating the disassembly of the filter plate 5. When the filter plate 5 needs to be installed, first insert the top end of the plug post 12 into the inner wall of the installation groove 13. At the same time, the drain pipe 3 is passed through the support plate 4 and inserted on the top of the filter plate 5. Then the threaded rod 7 is rotated to drive the rubber plate 16 to clamp the drain pipe 3. At this time, since the elastic member 9 is in a compressed state, it follows the rotation of the threaded rod 7 and gradually resets. The elastic force of the elastic member 9 is used to pull the two connecting ropes 11 to the left and reset, and drive the left side of the plug-in block 10 to gradually insert into the inner wall of the slot 14. In the process of clamping the drain pipe 3, the filter plate 5 can also be installed, thereby improving the use effect of the drainage device body 1 through linkage.

[0034] When the drain pipe 3 is in use, the drain pipe 3 is first passed through the right side of the support plate 4, and the filter plate 5 is installed with the support plate 4 by the two plug posts 12, thereby driving the bottom end of the drain pipe 3 to be inserted into the top of the filter plate 5, and then rotating the threaded rod 7 to drive the rubber plate 16 to slide to the left along the inner wall of the slide groove 6, and drive the connecting blocks 17 on the front and rear sides to slide along the inner wall of the auxiliary groove 15, thereby driving the rubber plate 16 to clamp the drain pipe 3. Since the rubber plate 16 is squeezed and pushed when it moves to the left, it is in a deformed state, thereby increasing the friction between the drain pipe 3 and the support plate 4 and improving the stability of its installation. When it needs to be disassembled, the threaded rod 7 is reversed to drive the rubber plate 16 to move to the right along the inner wall of the slide groove 6 and contract, thereby facilitating the disassembly of the drain pipe 3, and then the drain pipe 3 can be disassembled and assembled without the need for additional tools, thereby improving the use effect of the drainage device body 1;

[0035] When the drain pipe 3 is disassembled, the rubber plate 16 contracts to the right along the inner wall of the slide groove 6, thereby pulling the connecting ropes 11 on the front and rear sides to move to the right, thereby driving the plug-in block 10 to slide along the inner wall of the movable groove 8 and squeezing the elastic member 9, so that it is compressed on the inner wall of the movable groove 8. At this time, the left side of the plug-in block 10 is disengaged from the slot 14, making it convenient to pull the two plug posts 12 downward and disengage from the installation groove 13, thereby facilitating the disassembly of the filter plate 5. When the filter plate 5 needs to be installed, first insert the top end of the plug post 12 into the inner wall of the installation groove 13. At the same time, the drain pipe 3 is passed through the support plate 4 and inserted on the top of the filter plate 5. Then the threaded rod 7 is rotated to drive the rubber plate 16 to clamp the drain pipe 3. At this time, since the elastic member 9 is in a compressed state, it follows the rotation of the threaded rod 7 and gradually resets. The elastic force of the elastic member 9 is used to pull the two connecting ropes 11 to the left and reset, and drive the left side of the plug-in block 10 to gradually insert into the inner wall of the slot 14. In the process of clamping the drain pipe 3, the filter plate 5 can also be installed, thereby improving the use effect of the drainage device body 1 through linkage.
