[0002] Hydrogeological survey refers to the hydrogeological investigation and research work carried out to find out the hydrogeological conditions of a region. It aims to understand the causes, distribution and movement of groundwater and surface water, and provide a basis for the rational exploitation and utilization of water resources and the correct design and construction of foundation and piling projects. It includes two aspects: underground and above-ground hydrological surveys. Engineering hydrogeological surveys generally require the use of sampling devices.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: a sampling device for engineering hydrogeological survey, comprising a bottom plate 1, a frame 2 is fixed on the top of the bottom plate 1, a scale 3 is fixed on the top of the bottom plate 1, an adjusting component 200 for adjusting the height of the sampling device is installed inside the frame 2, and a sampling component 300 for sampling a target water source is installed at the bottom of the adjusting component 200;

[0024] Through the coordinated use of the base plate 1, the scale 3, the adjustment component 200 and the sampling component 300, in actual use, the water source at the target depth can be effectively sampled accurately, effectively avoiding the situation where the obtained water sample may be mixed with water from other depths, thereby ensuring the accuracy of the detection of the water source at the target depth, thereby ensuring that the expected use effect can be achieved, and improving the practicability of the sampling device used for engineering hydrogeological surveys.

[0025] In this embodiment, the adjusting component 200 is a structure for adjusting the height of the sampling component 300 .

[0026] like Figure 1 As shown, the adjustment component 200 includes a first motor 201 fixed to the inner top wall of the frame 2, the output shaft of the first motor 201 is fixed with a screw rod 202, the outer side of the screw rod 202 is threadedly connected with a threaded barrel 203, a limit rod 204 is fixed to the right side of the threaded barrel 203, the inside of the limit rod 204 is adjusted with a fixed rod 205, a moving block 206 is fixed to the left side of the threaded barrel 203, and a limit plate 207 is fixed to the outer side of the fixed rod 205.

[0027] It should be noted that the top end of the fixing rod 205 is fixed to the inner top wall of the frame 2, and the bottom end of the fixing rod 205 is fixed to the top of the bottom plate 1, so that the fixing rod 205 is fixed to ensure the stability of the upper and lower movements of the limiting rod 204.

[0028] In addition, the back side of the limit plate 207 is fixed to the inner rear side wall of the frame 2 to fix the limit plate 207 to ensure that the limit plate 207 can limit the limit rod 204. The adjustable distance from the bottom of the fixed rod 205 to the top of the limit plate 207 is smaller than the adjustable distance of the screw 202 in the threaded barrel 203, which effectively avoids the screw 202 and the threaded barrel 203 from falling off.

[0029] In addition, the moving block 206 is slidably connected to the outside of the scale 3, ensuring that the moving block 206 can facilitate the staff to read.

[0030] The sampling assembly 300 in this embodiment is a structure for accurately sampling water sources at a target depth.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the sampling assembly 300 includes an adjusting cylinder 301 slidably connected to the inner rear side wall of the frame 2, a sampling cup 302 is slidably connected inside the adjusting cylinder 301, a conical head 303 is threadedly connected to the bottom of the adjusting cylinder 301, a second motor 304 is fixed to the inner top wall of the adjusting cylinder 301, a rotating rod 306 is fixed to the output shaft of the second motor 304, a mounting plate 305 is fixed to the bottom of the second motor 304, connecting rods 307 are fixed to the left and right sides of the rotating rod 306, arc plates 308 are fixed to the opposite ends of the two connecting rods 307, and water inlet holes 309 are opened on the left and right sides of the adjusting cylinder 301.

[0032] It should be noted that a through hole 4 is provided at the top of the base plate 1, and the diameter of the through hole 4 is larger than the outer diameter of the adjusting cylinder 301, ensuring that the adjusting cylinder 301 can pass through the through hole 4 smoothly. Four fixing holes 5 are provided at the top of the base plate 1, which are convenient for fixing the base plate 1 through the fixing holes 5, thereby ensuring the stability of the sampling device 1.

[0033] In addition, the inner diameter of the adjusting cylinder 301 is equal to the outer diameter of the sampling cup 302, so that the sampling cup 302 is more stable in the adjusting cylinder 301. The mounting plate 305 is fixed inside the adjusting cylinder 301. The second motor 304 is installed more stably through the mounting plate 305. The top of the adjusting cylinder 301 is fixed to the bottom of the threaded cylinder 203, ensuring that the threaded cylinder 203 can drive the adjusting cylinder 301 to move up and down for adjustment.

[0034] In addition, the width and height of the arc plate 308 are much larger than the diameter of the water inlet 309, ensuring that the arc plate 308 can effectively block the water inlet 309. The second motor 304 rotates clockwise, and is set to rotate 180° each time when it is on, and each rotation interval is five seconds, ensuring that after the second motor 304 is turned on, it can drive the arc plate 308 to rotate to release the blockage of the water inlet 309, thereby allowing the water from the outside to enter the regulating cylinder 301. After five seconds, the arc plate 308 is driven to block the water inlet 309, and then the second motor 304 can be turned off.

[0035] The working principle of the above embodiment is:

[0036] When in use, first fix the bottom plate 1 to the target location through the fixing hole 5, and ensure that the through hole 4 is located above the target drill hole, then put the sampling cup 302 on the conical head 303, and then rotate the conical head 303 to fix the conical head 303 and the adjusting cylinder 301, and then turn on the first motor 201 to drive the screw rod 202 to rotate, and the threaded cylinder 203 moves up and down on the outside of the screw rod 202 under the rotation thrust of the internal thread and the limiting action of the limiting rod 204, thereby driving the adjusting cylinder 301 to move up and down and adjust, and at the same time drives the moving block 206 to move up and down on the outside of the scale 3 to adjust, so that the staff can judge the depth conveniently. When the adjusting cylinder 301 reaches the target depth, turn on the second motor 3. 04, the arc plate 308 is driven to rotate by the rotating rod 306 and the connecting rod 307, so that the arc plate 308 loses the limit on the water inlet hole 309, so that the water outside the regulating cylinder 301 enters the regulating cylinder 301 through the water inlet hole 309 and is stored in the sampling cup 302. The second motor 304 rotates again after an interval of five seconds, so that the arc plate 308 closes the water inlet hole 309 again, thereby completing the sampling of the water source at the target depth. Subsequently, the conical head 303 is rotated to separate the conical head 303 from the regulating cylinder 301, and the sampling cup 302 can be taken out of the regulating cylinder 301. The conical head 303 should be rotated slowly to prevent the sampling cup 302 from falling off when it is separated from the regulating cylinder 301 due to excessive speed.

[0037] Compared with the prior art, the sampling device for engineering hydrogeological survey, through the coordinated use of the base plate 1, the scale 3, the adjustment component 200 and the sampling component 300, can effectively and accurately sample the water source at the target depth during actual use, effectively avoiding the situation where the obtained water sample may be mixed with water from other depths, thereby ensuring the accuracy of the detection of the water source at the target depth, thereby ensuring that the expected use effect can be achieved, improving the practicability of the sampling device for engineering hydrogeological survey, and solving the problem of low practicability of the existing sampling device for engineering hydrogeological survey.
