AI Technical Summary
Existing mine water sample extraction and filtration devices cannot clean the filter screen in a timely manner, resulting in the accumulation of impurities. Furthermore, water samples from different water layers are easily mixed, making it impossible to achieve single-sampling and multi-group sealing.
The sampling tube is adjusted by rotating the shaft, with a certain interval time, so that the sampling tube is filled with liquid in a static state. The rotating shaft also drives the filter screen to change the filtration position. Combined with the reciprocating block and brush head to clean impurities, a single tube can be sampled and multiple sets of seals can be achieved.
This method ensures that single-sampling is less prone to mixing, prevents impurities from accumulating on the filter screen, and guarantees water sample separation and clean filtration.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of water sample extraction technology. Specifically, it is a mine water sample extraction and filtration device. Background Technology
[0002] During the mining process, since the minerals are buried deep underground, it is necessary to test the groundwater in the mining area and the surrounding area. The places that need to be tested are generally the drilled wells and the groundwater channels opened up by the drills. At the same time, geological water needs to be sampled to facilitate the analysis of water quality.
[0003] The sampling area contains a large amount of silt and debris, and filters are usually used for filtration. However, existing extraction and filtration devices cannot clean the filters in a timely manner, and the water samples from the sampling water layer are easily mixed with water samples from other water layers, making it impossible to isolate water samples from different water layers. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is to provide a mine water sample extraction and filtration device that can drive the sampling tube to adjust its position through a rotating shaft and has a certain interval time so that the sampling tube can be stationary, which facilitates the filling of the sampling tube with liquid. By rotating the sampling tube to take samples, the device can achieve the effect of single sampling and multiple sealing, making the samples less likely to mix.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] The device includes a pipe body, an internal rotating shaft, a mounting plate rotatably mounted in the middle of the pipe body, a sampling tube mounted on the surface of the mounting plate, a driving block rotatably mounted on one side of the rotating shaft, a driving column mounted on the lower surface of the mounting plate, a partition installed inside the pipe body, a shielding frame mounted on the upper surface of the partition, a water inlet located below the partition, a through hole on one side of the pipe body, a filter screen rotatably mounted on one side of the partition, and a rotating shaft engaging one side of the filter screen.
[0007] The technical solution of this utility model has achieved the following beneficial technical effects:
[0008] The rotating shaft can adjust the position of the sampling tube and has a certain interval to allow the sampling tube to remain stationary, which facilitates the filling of the sampling tube with liquid. By rotating the sampling tube, a single sampling can achieve the effect of multiple sealing groups, making the samples less likely to mix. The rotating shaft can also drive the filter screen to rotate, causing the filter screen to change its filtration position and preventing impurities from accumulating on the filter screen due to prolonged residence. The rotating shaft can also cause the reciprocating block at the bottom to move back and forth, cleaning impurities from the surface of the filter screen. Attached Figure Description

[0014] This implementation example is attached to the instruction manual. Figure 1 As shown, the tube 1 of this solution is a hollow tube. Inside the tube 1, there is a rotatable rotating shaft 2. The rotating shaft 2 needs to be driven by a motor to rotate. The motor is located above the rotating shaft 2. Since the motor is existing technology, this solution will not describe the motor in detail. The motor used in this solution is a servo motor. The motor has a power-off self-locking function, and a support installation position for the complete motor needs to be reserved at the top of the tube 1. The upper and lower ends of the tube 1 can be disassembled. The lower end of the tube 1 is an impact frame, which is fastened to the lower end of the tube 1. The upper end of the tube 1 is a threaded cap, which can also be disassembled. The two sides of the tube 1 can be equipped with rings for easy rope suspension, so that the tube 1 can be suspended below the water surface.
[0015] As per the instruction manual Figure 2 As shown, the instruction manual is attached. Figure 2 The tube 1 was cut in half to reveal its interior. The rotating shaft 2 runs through the center of the tube 1 and has three sets of structures: upper, middle, and lower. First, there is the driving block 5, which is rotatably mounted on one side of the rotating shaft 2. A torsion spring, or driving spring 18, is located at the edge of the center of rotation of the driving block 5. The driving spring 18 is viewed from below, so it cannot be fully shown. The purpose of the driving spring 18 is to keep the driving block 5 in the position shown in the instruction manual. Figure 3The configuration shown allows the drive block 5 to rotate and then reset. The purpose of drive block 5 is to rotate the mounting plate 3. Since the sampling tube 4 is mounted on the mounting plate 3 (which can be understood as an integral part, but can also be fixed with bolts or other means for continuous use), the sampling tube 4 can be rotated to adjust its position. The sampling tube 4 has a side opening 19 on one side and an inlet at the bottom. Only one sampling tube 4 is shown in the attached instruction manual. Figure 2 As shown, it can communicate with the outside world. For example, the other three sampling tubes 4 will form a barrier under the action of the tube body 1 and the partition 7. Because the inner wall of the tube body 1 is made of sealing material, and the top of the partition 7 is also made of sealing material, it will be sealed as the sampling tube 4 rotates.
[0016] As per the instruction manual Figure 3 As shown, the drive block 5 controls the rotation of the sampling tube 4 (i.e., the mounting plate 3). Two drive columns 6 are located below the mounting plate 3, with an included angle of 45 degrees between them reaching the center of the mounting plate 3. A shielding frame 8 is located above the partition plate 7 (the shielding frame 8 can be integrally mounted above the partition plate 7). Above the shielding frame 8 are four strips, with an angle of 90 degrees between these four strips reaching the center of the plate. Figure 2 As shown, one of the driving posts 6 is already hidden above the four strips. When the rotating shaft 2 rotates counterclockwise, after a 45-degree rotation, the left driving post 6 will rotate to the left side of the four strips (while the right driving post 6 is exposed in the upper left). At this point, under the action of the blocking bracket 8, the driving block 5 is forced to rotate, which in turn twists the driving spring 18, passing over the left driving post 6. As the rotating shaft 2 rotates 315 degrees, it will encounter the exposed driving post 6 in the upper left corner, as shown in the instruction manual. Figure 2 As initially described, the cycle of motion is repeated, thus driving block 5 to drive column 6 to specific positions with intervals, and the maximum rotation is 45 degrees, as per the instruction manual. Figure 2 The 45-degree rotation shown in the diagram ensures that all sampling tubes 4 in this scheme are sealed, and allows for a time interval. It also allows time for the liquid to fill the sampling tube 4 after the tube body 1 is submerged in water, thus completing the sampling.
[0017] The above describes how the rotating shaft 2 drives the sampling tube 4 to operate in an orderly manner. A gear is installed in the middle of the rotating shaft 2, as shown in the instruction manual. Figure 3 As shown, a filter screen 11 is rotatably disposed on the surface of the partition 7. The filter screen 11 extends through the top of the partition 7 and has a gear that can mesh with the rotating shaft 2, so that the rotating shaft 2 drives the filter screen 11 to rotate. The rotation of the filter screen 11 can change the filtering position.
[0018] As per the instruction manual Figure 2As shown, the sampling tube 4 on the left is in the sampling state at this time, and the upper and lower parts are connected, so that the liquid can automatically fill the sampling tube 4. After the sampling tube 4 is rotated 45 degrees, the upper and lower parts of the sampling tube 4 will be sealed.
[0019] As per the instruction manual Figure 4 As shown, a control disk 12 is located at the lower end of the rotating shaft 2. A control groove 13 is formed on the upper surface of the control disk 12. The distance from the control groove 13 to the center of the circle continuously changes. A reciprocating block 14 is attached to the control groove 13. The reciprocating block 14 is laterally slidably disposed inside the partition 7. Therefore, as the control disk 12 rotates, the reciprocating block 14 moves back and forth, as shown in the attached instruction manual. Figure 2 As shown, the brush head 15 is rotated above the reciprocating block 14. One side of the brush head 15 is a common household brush. To ensure that the brush in this design cleans in one direction, the brush is rotated and positioned above the reciprocating block 14. A guide block 17 is provided on one side of the brush, as shown in the instruction manual. Figure 4 The guide block 17 shown is mounted on the partition 7 and corresponds to the movement trajectory of the brush. Figure 4 As the control panel 12 rotates clockwise, the reciprocating block 14 slides downwards and to the right. A rotational spring 16, which is also a torsion spring, is located on one side of the center of rotation of the brush head 15, ensuring that the brush head 15 remains as described in the instruction manual. Figure 4 At this position, as the reciprocating block 14 moves, the cylinder on one side of the brush head 15 (the brush head 15 has a cylinder on one side) will contact the inclined surface of the lower left side of the guide block 17, forcing the brush head 15 to move away from the filter screen 11. After the reciprocating block 14 reaches the right side, it will reach the right inclined surface of the guide block 17, and the rotating spring 16 will reset, causing the cylinder to move upward under the action of the inclined surface of the guide block 17. That is, the brush head 15 rotates and moves closer to the filter screen 11, achieving the effect of one-way contact with the filter screen 11. In other words, the brush head 15 cleans the filter screen 11 on one side, while the brush head 15 is retracted on the other side.

A water inlet 9 is opened below the baffle 7. A through hole 10 is provided on one side of the pipe body 1. A filter screen 11 is rotatably mounted on one side of the baffle 7. The rotating shaft 2 is engaged on one side of the filter screen 11. A control plate 12 is mounted on one end of the rotating shaft 2. A control panel is opened on the top of the control plate 12. The surface of the control tank 13 is connected to a reciprocating block 14, which is slidably disposed on one side of the partition 7. A brush head 15 is rotatably disposed on one side of the reciprocating block 14, and a rotating spring 16 is disposed on one side of the brush head 15. A guide block 17 is disposed on one side of the partition 7. A motor is installed inside the tube body 1, and a rotating shaft 2 is installed at the output end of the motor.
