Description

Technical Field

[0001] The utility model relates to the technical field of water extraction devices, in particular to a drilling water extraction device for preventing and controlling groundwater pollution. Background Art

[0002] With the rapid development of industrial production, the problem of groundwater pollution in my country has become increasingly prominent, and the impact of groundwater pollution on the environment and economic development has become increasingly apparent. Therefore, it is necessary to carry out necessary monitoring, and once groundwater pollution is found, timely measures should be taken to prevent it from happening. When monitoring groundwater, it is usually necessary to use drilling equipment to drill monitoring wells and take samples regularly through water sampling devices.

[0003] When the water extractor is in use, the water intake pipe is positioned on the center pole so that it is at a certain distance from the plug below and is lowered into the monitoring well. After water extraction is completed, the collision block is made to fall vertically along the cable and hit the water intake pipe, so that it is separated from the center pole and connected to the plug below. However, the position of the water intake pipe in the well cannot be controlled, and the sampling tube and cable in the detection well are easy to stick to the well wall, making it easy for the counterweight block to collide with the well wall during the falling process and reduce the impact force, thereby reducing the impact effect on the water intake pipe, making it difficult for the water intake pipe to be separated from the center pole, and thus unable to be connected and closed with the plug, reducing the water extraction effect.

[0004] Therefore, a drilling water extraction device for preventing and controlling groundwater pollution is proposed. Utility Model Content

[0027] The end of the center rod 2 away from the cable 1 is fixedly connected with a plugging assembly, and the plugging assembly is detachably connected to the end of the water intake pipe 3 away from the counterweight block 4. When the positioning assembly is separated from the counterweight block 4, the plugging assembly is connected to the water intake pipe 3;

[0028] Two support blocks 6 are symmetrically fixed on the outer wall of the counterweight block 4, and screws 7 are fixed on the support blocks 6. A support rod 24 is slidably connected to the screw 7, and a locking nut 8 is threadedly connected to the screw 7. The support rod 24 is located between the support block 6 and the locking nut 8, and a roller 9 is rotatably connected to the end of the support rod away from the counterweight block 4.

[0029] According to a further optimized solution, the positioning assembly includes a positioning block 10 fixedly connected to the center rod 2, the positioning block 10 is located at the connection between the cable 1 and the center rod 2, and a positioning groove 11 is formed at one end of the counterweight block 4 close to the cable 1, and the positioning groove 11 is clamped with the positioning block 10.

[0030] According to a further optimized solution, an avoidance groove 12 is provided at one end of the collision block 5 close to the positioning block 10 . When the collision block 5 collides with the counterweight block 4 , the avoidance groove 12 is covered outside the positioning block 10 .

[0031] A further optimized solution is that the sealing assembly includes a plugging cover 13 fixedly connected to the end of the center rod 2 away from the cable 1, the outer wall of the plugging cover 13 is slidably connected to the inner wall of the water intake pipe 3, a first magnetic ring 14 is fixedly connected to the outer wall of the plugging cover 13, and a second magnetic ring 15 is fixedly connected to the outer wall of the water intake pipe 3 near the end of the plugging cover 13. When the plugging cover 13 slides into the inner wall of the water intake pipe 3, the first magnetic ring 14 is magnetically attracted to the second magnetic ring 15.

[0032] To further optimize the solution, an end of the blocking cover 13 away from the water intake pipe 3 is fixedly connected to a water outlet pipe 16 , a switch 17 is fixedly connected to the water outlet pipe 16 , and a water flow channel 18 connected to the water outlet pipe 16 is opened on the water intake pipe 3 .

[0033] To further optimize the solution, a conical block 19 is fixedly connected to the center rod 2 , and a conical groove 20 is formed at one end of the counterweight block 4 away from the positioning groove 11 . When the first magnetic ring 14 is magnetically attracted to the second magnetic ring 15 , the conical block is inserted into the conical groove 20 .

[0037] The starting motor 22 drives the cable 1 to extend, so that the water intake pipe 3 can be continuously lowered to the bottom of the monitoring well. When lowering, the positioning block 10 is stuck in the positioning groove 11. At this time, the plugging cover 13 is separated from the water intake pipe 3, thereby opening the bottom of the water intake pipe 3. When the water intake pipe 3 is full of water, the collision block 5 is manually lowered to make it fall along the cable 1 and collide with the counterweight block 4. The counterweight block 4 is subjected to a strong impact force, so that the positioning block 10 is separated from the positioning groove 11 on the counterweight block 4. At this time, the water intake pipe 3 sinks downward under the action of gravity and impact force, so that the plugging cover 13 slides into the water intake pipe 3. At the same time, the first magnetic ring 14 and the second magnetic ring 15 are adsorbed together, and the conical block 19 is inserted into the conical groove 20, thereby blocking both ends of the water intake pipe 3. Then the cable 1 is lifted to lift the water intake pipe 3 up. Turn on the switch 17 to divide the samples in the water intake pipe 3 into different sample bottles for sealing.
