Description

Technical Field

[0001] The utility model relates to the field of hydrological stratified water sample drilling, and particularly relates to a device for drilling hydrological exploration stratified water samples. Background Technique

[0002] The device for drilling stratified water samples in hydrological exploration is usually used to obtain groundwater samples during geological exploration, so as to analyze the water quality characteristics, stratum structure and groundwater flow conditions at different depths. Such devices are widely used in fields such as hydrogeological surveys, environmental monitoring and groundwater resource assessment. Its main function is to collect water samples from groundwater layers at different depths to ensure that the obtained data can accurately reflect the property differences of water bodies in each layer. The working principle is that during the drilling process, through special sampling equipment such as water sample bottles and closed water samplers, water samples are collected in strata at different depths. These devices usually need to obtain water samples from multiple layers or different water level layers without damaging the groundwater layer structure.

[0003] In the specific drilling and sampling of water at different levels, the usual devices directly drill holes in the ground, and then use water sampling devices to sequentially sample and test the water at different levels to achieve sampling of water at different levels. Although this method can sample water, it is more laborious to sample and has a low efficiency of sampling water, which is not convenient for the operator to use. Content of the Utility Model

[0024] Refer to Figures 1 - 4, the present utility model provides a technical solution: a layered water sample drilling device for hydrogeological exploration, including a vehicle body 11, above which there is a motor 14, the output end of the motor 14 is provided with a mounting frame 15, the bottom of the mounting frame 15 is provided with a mounting pipe 16, one side of the mounting pipe 16 is provided with a number of solenoid valves 17, inside the mounting pipe 16 there is a water storage cavity 18, inside the water storage cavity 18 there are a number of limiting rings 19, inside the mounting frame 15 there is a negative pressure pump 2, the bottom of the negative pressure pump 2 is provided with a fixed pipe 21, the bottom of the mounting pipe 16 is provided with a drill bit 25. Through the mutual cooperation of the vehicle body 11, hydraulic cylinder 12, mounting frame 13, motor 14, mounting frame 15, mounting pipe 16, drill bit 25, solenoid valve 17, water storage cavity 18 and filter screen 22, when the operator needs to simultaneously sample water at different levels, the operator can first move the vehicle body 11 to the position where drilling and water sampling are required. Then the operator can start the hydraulic cylinder 12 to drive the mounting frame 13 to move downward. When the mounting frame 13 moves, it can drive the motor 14 to move simultaneously. At this time, the operator can start the motor 14 to drive the mounting frame 15 to move simultaneously. The mounting frame 15 can drive the mounting pipe 16 to rotate, and the mounting pipe 16 drives the drill bit 25 to perform drilling operations on the ground. Through the continuous movement of the hydraulic cylinder 12, drilling operations on the ground can be carried out. When the drilling is completed, the operator can open the solenoid valves 17 at different depths, so that not only can water at different levels enter the interior of the water storage cavity 18, but also when the water enters, the water can be filtered by setting the filter screen 22. Thus, water at different levels can be collected at one time, which is convenient for the operator to perform subsequent detection and use.

[0025] Refer to Figures 1 - 4 , in a preferred embodiment, there is a support frame 3 on the top of the vehicle body 11, a hydraulic cylinder 12 is provided on the top of the support frame 3, the bottom of the hydraulic cylinder 12 is provided with a mounting frame 13, the motor 14 is arranged inside the mounting frame 13, there is a mounting groove 26 on the surface of the vehicle body 11, the size of the mounting groove 26 is larger than that of the mounting frame 13, a limiting groove 27 is opened inside the mounting groove 26, a number of mounting holes 23 are opened on the surface of the fixed pipe 21, a number of filter screens 22 are arranged inside the water storage cavity 18, and the filter screens 22 are arranged on one side of the mounting holes 23. Through the mutual cooperation of the negative pressure pump 2, fixed pipe 21, filter screen 22 and water storage cavity 18, when the operator needs to improve the sampling efficiency of water, the operator can start the negative pressure pump 2. The negative pressure pump 2 can generate negative pressure pumping inside the fixed pipe 21 during the sampling process. Under the action of negative pressure, it is easier for water to enter the water storage cavity 18 through the filter screen 22. Thus, not only can the water intake efficiency be improved, but also the loss of water can be prevented, and it is convenient for the subsequent operator to sample water and convenient for the operator to use.

[0026] Refer to Figures 1 - 4In a preferred embodiment, a plurality of drain valves 24 are provided on the other side of the mounting tube 16, the size of the drill bit 25 is larger than the size of the mounting tube 16, a push handle 28 is provided on the top of the vehicle body 11, and an anti-slip cover is provided on the surface of the push handle 28.

By providing the baffle, sand can be prevented from entering the mounting tube 16.

[0027] Specifically, the working process or working principle of the hydrological exploration stratified water sampling drilling device is as follows: in the specific drilling sampling of different water layers, the usual device is to directly drill holes in the ground, and then use the water sampling device to sample and test the water at different layers in turn to achieve sampling of water at different layers. Although this method can sample water, sampling is more troublesome and the efficiency of water sampling is low, which is inconvenient for the operator to use. Therefore, the technical solution can solve the above problems. When the operator needs to sample water at different layers at the same time, the operator can first move the vehicle body 11 to the position where drilling and water sampling are required, and then the operator can start the hydraulic cylinder 12 to drive the mounting frame 13 to move downward. When the mounting frame 13 moves, it can drive the motor 14 to move at the same time. At this time, the operator can start the motor 14 to drive the mounting frame 15 to move at the same time, and the mounting frame 15 can drive the mounting pipe 16 to move. The mounting tube 16 drives the drill bit 25 to perform a drilling operation on the ground. Through the continuous movement of the hydraulic cylinder 12, the ground can be drilled. When the drilling is completed, the operator can open the solenoid valves 17 of different depths, so that not only can water of different layers enter the interior of the water storage chamber 18, but also when the water enters, the water can be filtered by setting the filter net 22, so that the water of different layers can be collected at one time, which is convenient for the operator to use for subsequent testing. When the operator needs to improve the sampling efficiency of water, the operator can start the negative pressure pump 2. The negative pressure pump 2 can use the negative pressure pump 2 to generate negative pressure suction inside the fixed tube 21 during the sampling process. Under the action of negative pressure, it is easier for water to pass through the filter net 22 into the water storage chamber 18, which can not only improve the efficiency of water extraction, but also prevent the loss of water, and facilitate the subsequent operator to sample water and use it conveniently. At this point, all processes are completed.

Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
