Description

Technical Field

[0001] The utility model belongs to the field of hydrogeological drilling, and particularly relates to a layered water-stop device for hydrogeological drilling. Background Technique

[0002] The hydrogeological drilling situation in areas with multiple aquifers is relatively complex. In order to obtain complete and accurate information such as the water volume, water level, and water quality of each aquifer, it is necessary to conduct water-stop and pumping tests on each aquifer separately. Layered pumping is an important part of hydrogeological exploration technology, which can not only promote the smooth progress of engineering project planning and construction work, but also play an important guiding role in modern urban construction.

[0003] According to the Chinese patent with the publication number "CN219511887U", a layered water-stop device for hydrogeological drilling is disclosed, including: a tank body assembly connected to an external lifting device; a multi-stage water intake assembly including a control cable provided, a hydraulic cylinder connected to the lower end of the control cable, a first telescopic rod, a second telescopic rod, and a third telescopic rod connected to the lower end of the hydraulic cylinder, a first partition plate and a first baffle connected to the first telescopic rod, a second partition plate and a second baffle connected to the second telescopic rod, a third partition plate and a third baffle connected to the third telescopic rod; a protection assembly. The existing water intake device for hydrogeological drilling needs to take water repeatedly many times to obtain water bodies at different underground levels. The labor intensity of the operation is large, and the equipment is damaged more seriously. By arranging the first telescopic rod, the second telescopic rod, and the third telescopic rod that can be controlled in multiple stages in the water intake tank body, and each telescopic rod body is provided with a partition plate and a block, the water bodies of different underground layers can be obtained separately at one time without interference from each other. The equipment structure is simple and the operation is convenient;

[0004] From the above structure, it can be seen that by arranging the first telescopic rod, the second telescopic rod, and the third telescopic rod that can be controlled in multiple stages in the water intake tank body, and each telescopic rod body is provided with a partition plate and a block, the water bodies of different underground layers can be obtained separately at one time without interference from each other. The equipment structure is simple and the operation is convenient. When in specific use, the tank body assembly and the multi-stage water intake assembly are installed respectively, and the first telescopic rod, the second telescopic rod, and the third telescopic rod are controlled through the control cable, so that the first baffle, the second baffle, and the third baffle just seal the first water inlet. The equipment is put into the water intake hole. When reaching the bottom water intake layer, the third telescopic rod is adjusted to open the third baffle, so that the water body flows into the interior of the water intake tank shell through the first water inlet. From the above structure, it can be seen that the above device conducts the layered sampling effect of water samples through a complex structure, which increases the production cost of the device, and at the same time, it is inconvenient to maintain due to the complex structure when the device needs to be maintained.

Under the rotation of the water intake motor, the connecting rod rotates. Under the rotation of the connecting rod, the driving bevel gear rotates. The rotation of the driving bevel gear causes the driven bevel gear to rotate, thereby causing the screw rod to rotate. Under the rotation of the threaded rod, the screw barrel moves on the surface of the screw rod, causing the baffle to be moved out of the inner part of the water inlet. Thus, water can enter the inner part of the water intake cavity through the water inlet, achieving the effect of stratified water intake. Then, after the water intake is completed, the water intake motor can be reversed to make the baffle contact the water inlet, so that the water inlet is closed to block the outflow of water.

[0016] Second, first, control the retracting and releasing motor to make the winding rod rotate. Under the rotation of the winding rod, the fixed box and the wire will move downward along with the water intake component. Thus, the winding rod can exert a traction effect on the water intake component, and when the retracting and releasing component is reversed, the water intake component can be pulled up. Furthermore, it is more convenient to take water. When the water intake cylinder extends out of the hole after the water intake is completed, rotate the bidirectional lead screw. Under the action of the threaded hole, the fixed plates move closer together. When the fixed plates move closer together, they will contact the water intake cylinder. Thus, the fixed plates can exert a clamping effect on the water intake component, increasing the stability of the water intake component during water intake. BRIEF DESCRIPTION OF THE DRAWINGS

The bidirectional lead screw 51 is threadedly connected to the threaded holes 52; by rotating the bidirectional lead screw 51, the fixing plates 53 approach each other under the action of the threaded holes 52, and when the fixing plates 53 approach each other, they will contact the water intake cylinder 31, so that the water intake assembly 3 can be clamped under the action of the fixing plates 53, increasing the stability of the water intake assembly 3 when taking water.

[0027] Reference Figure 2 , the fixing plates 53 are slidably connected to the inner side of the bracket 1. Limiting slide rods 16 are fixedly connected to the inner side of the bracket 1. Limiting holes 15 are formed in the other ends of the fixing plates 53.

[0028] Reference Figure 1 The other end of the bidirectional lead screw 51 penetrates through the bracket 1 and is fixedly connected to a turntable 8. The other end of the turntable 8 is fixedly connected to the outer ring of a bearing 9, and the inner ring of the bearing 9 is fixedly connected to a handle 10. First, hold the handle 10. After holding the handle 10, then rotate the turntable 8. Under the rotation of the turntable 8, the bidirectional lead screw 51 fixedly connected thereto can be rotated. Thus, with the arrangement of the handle 10 and the turntable 8, it is convenient to rotate the bidirectional lead screw 51.

[0029] Principle and advantages of use: First, control the winding and unwinding motor 25 to rotate the winding rod 21. Under the rotation of the winding rod 21, the fixed box and the wire 24 will move downward along with the water intake assembly 3. Thus, under the action of the winding rod 21, the water intake assembly 3 can be pulled. Put the water intake cylinder 31 into the hole through the winding and unwinding assembly 2. Then, after placing the water intake cylinder 31 in a suitable position, control the water intake motor 34 to rotate through the switch 11 and the wire 24. Under the rotation of the water intake motor 34, the connecting rod 44 rotates. Under the rotation of the connecting rod 44, the driving bevel gear 42 rotates. The rotation of the driving bevel gear 42 causes the driven bevel gear 43 to rotate, thereby causing the screw rod 37 to rotate. Under the rotation of the threaded rod, the screw barrel 38 moves on the surface of the screw rod 37 to move the baffle 39 out of the water inlet 40. Thus, water can enter the water intake cavity 33 through the water inlet 40, achieving the effect of stratified water intake. Then, after the water intake is completed, reverse the water intake motor 34 to make the baffle 39 contact the water inlet 40, so that the water inlet 40 is closed to block the outflow of water. Then, when reversing the winding and unwinding assembly 2, the water intake assembly 3 can be lifted, making it more convenient to take water. When the water intake cylinder 31 extends out of the hole after the water intake is completed, rotate the bidirectional lead screw 51. Under the action of the threaded hole 52, the fixing plates 53 move closer together. When the fixing plates 53 move closer together, they will contact the water intake cylinder 31. Thus, under the action of the fixing plates 53, the water intake assembly 3 can be clamped, increasing the stability of the water intake assembly 3 during water intake.
