[0025] The present invention provides a sampling device for water conservancy environment survey, and its beneficial effects include:

[0026] 1. The setting of the sampling mechanism can effectively reduce the disturbance of the sample. When the first piston is inserted into the sludge, it can block the mixing of the surrounding sludge to a certain extent and maintain the purity of the sample. During the advancement of the second piston, it can also further reduce the interference of external factors on the sample, so that the obtained sludge sample can more truly reflect its in-situ state.

[0027] 2. Through the setting of the material receiving mechanism, the sampled sludge can be squeezed and drained. The physical properties of the drained sludge can be measured more accurately. When measuring the dry density of the sludge, the drained sample can eliminate the interference of moisture on the measurement result. Dry density is an important physical parameter of the sludge. It is related to the compaction degree and pore structure of the sludge. Measuring the dry density of the drained sample can better understand the engineering properties of the sludge.

[0028] 3. Through the setting of density measurement mechanism, the silt density can be measured at the location where the silt is obtained. In construction projects and water conservancy projects, accurate measurement of silt density is crucial to assessing the stability of the foundation. Silt with different densities has different diffusion and adsorption capabilities for pollutants. Accurate measurement of silt density can provide an important basis for pollution control and environmental risk assessment. BRIEF DESCRIPTION OF THE DRAWINGS

The staff keeps the sampling time of the entire sampling device consistent, and thus the number of hammerings can be kept consistent. The downward movement of the fifth threaded rod 407 can drive the fourth pulley 421 to rotate, and the rotation of the fourth pulley 421 can drive the second threaded cylinder 426 to rotate, and the rotating second threaded cylinder 426 can make the seventh threaded rod 424 move upward, and then the third piston plate 423 can move upward.The staff can judge the density of the sludge by the height of the third piston plate 423 inside the scale box 422.

[0045] Reference Figure 1-Figure 10 This embodiment also proposes a sampling method for water conservancy environment survey, which is applicable to the above-mentioned sampling device for water conservancy environment survey, and the steps are as follows:

[0046] S1: First, the staff pushes the entire device to the position where sampling is required, and then starts the first motor 201, the first motor 201 can drive the first threaded rod 202 to rotate, the rotation of the first threaded rod 202 can drive the mounting plate 204 to move on the surface of the support column 203, and then determine the height of the mounting plate 204 on the support column 203 according to the sampling depth;

[0047] S2: Then start the second motor 205, which can drive the rotating cylinder 206 to rotate. In the initial state, the height of the first piston plate 212 is higher than the feed port 208, and the fluid sludge enters between the first piston plate 212 and the second piston plate 215 through the feed port 208, and then the second motor 205 is reversed to suck the obtained sludge into the interior of the sampling cylinder 207;

[0048] S3: When the sludge reaches the inside of the receiving box 301, the two clamping plates 319 are driven by the double-groove pulley 310 to move closer to or farther from each other, so that the squeezing plate 320 squeezes the sludge inside the receiving box 301, so that the water in the sludge falls to the bottom of the receiving box 301 through the filter plate 321, thereby achieving solid-liquid separation of the sludge;

[0049] S4: At the same time, the hammer head 409 hammers inside the hammer box 405, and the staff can judge the density of the sludge by the height of the third piston plate 423 inside the scale box 422;

[0050] S5: Then the second motor 205 is stopped, the first motor 201 is reversed, the entire sampling device is lifted, and the staff takes out the separated sludge and water for testing.

[0051] Specifically, the working process or working principle of the sampling device for water conservancy environment survey is as follows: first, the staff pushes the entire device to the position where sampling is required, and then starts the first motor 201. The first motor 201 can drive the first threaded rod 202 to rotate. The rotation of the first threaded rod 202 can drive the mounting plate 204 to move on the surface of the support column 203, so that the height of the mounting plate 204 can be changed, thereby accurately sampling the depth. Then, the second motor 205 is started. The second motor 205 can drive the rotating cylinder 206 to rotate. When the rotating cylinder 206 rotates driven by the second motor 205, it can drive the gear ring 209 to rotate. The rotation of the gear ring 209 can drive the two first gears 210 to rotate. The rotation of the rotating cylinder 206 can drive the sliding plate 216 to rotate. The rotation of the sliding plate 216 can drive the second threaded rod 211 to move up and down. The up and down movement of the second threaded rod 211 can drive the first piston plate 212 The first gear 210 moves up and down inside the sampling barrel 207. When the first gear 210 rotates, the second gear 213 can be driven to rotate. The rotation of the second gear 213 can drive the third threaded rod 214 to move up and down. The up and down movement of the third threaded rod 214 can drive the second piston plate 215 to move up and down inside the sampling barrel 207. When the staff needs to take samples, the first piston plate 212 is at the bottom of the second piston plate 215. In the initial state, the height of the first piston plate 212 is higher than the feed port 208. Driven by the second motor 205, the first piston plate 212 moves downward, so that the debris entering the sampling barrel 207 is squeezed downward, and the fluid sludge enters between the first piston plate 212 and the second piston plate 215 through the feed port 208. Then the second motor 205 is reversed to move the first piston plate 212 and the second piston plate 215 upward, and the obtained sludge is sucked into the interior of the sampling barrel 207.

[0052] The silt inside the sampling cylinder 207 can enter the interior of the receiving box 301, and the fixing foot 302 can fix the entire sampling cylinder 207 in the silt at the bottom of the water to prevent the sampling cylinder 207 from rotating together with the rotating cylinder 206. When the rotating cylinder 206 rotates, the rotating rotating cylinder 206 can drive the double-groove pulley 310 to rotate, and the rotating double-groove pulley 310 can drive the first pulley 309 to rotate. The rotating first pulley 309 can drive the first rotating shaft 307, and the rotating first rotating shaft 307 can drive the second bevel gear 308 to rotate. The rotating second bevel gear 308 can drive the first bevel gear 304 to rotate, and the rotation of the first bevel gear 304 can drive the rotating disk 305 to rotate. The rotation of the rotating disk 305 can drive the eccentric plate 311 to rotate eccentrically, and the eccentric plate 311 can rotate eccentrically. The eccentric rotation of 1 can make the fourth threaded rod 312 slide up and down, and the up and down sliding of the fourth threaded rod 312 can drive the first threaded cylinder 314 to rotate, thereby driving the second pulley 313 to rotate, and the up and down movement of the fourth threaded rod 312 can drive the connecting column 315 to move up and down, and the up and down movement of the connecting column 315 can drive the first mounting block 316 to slide up and down on the inner wall of the material receiving box 301, and the up and down movement of the first mounting block 316 can drive the sliding block 317 to slide horizontally on the inner wall of the material receiving box 301 under the action of the rotating plate 318, so that the two clamping plates 319 can move closer to or away from each other, so that the extrusion plate 320 squeezes the sludge inside the material receiving box 301, so that the water in the sludge falls to the bottom of the material receiving box 301 through the filter plate 321.

[0053] When the second pulley 313 rotates, the third pulley 402 can be driven to rotate. When the third pulley 402 rotates, the rotating third pulley 402 can drive the sixth threaded rod 419 to move up and down. The up and down movement of the sixth threaded rod 419 can drive the electric telescopic rod 418 to move up and down. The up and down movement of the electric telescopic rod 418 can drive the second mounting block 411 to move up and down inside the hammer box 405. When the second mounting block 411 moves downward, the arc plate 412 can be driven to move downward. When the arc plate 412 contacts the connector 410, the arc plate 412 rotates under the action of the connector 410. At this time, the arc plate 412 pushes the sliding sleeve 415 to squeeze the spring 417. The shape of the connector 410 is thick at the top and thin at the bottom. When the arc plate 412 moves to the thinner end of the connector 410, the arc plate 412 returns to its original shape under the action of the spring 417, so that the arc plate 412 can clamp the connector 410. At this time, the arc plate 412 moves upward under the action of the sixth threaded rod 419, so that the hammer head 409 moves upward. The arc plate 412 moves in a row, and when the arc plate 412 moves to the toggle groove 420, the toggle groove 420 squeezes the top of the arc plate 412, so that the bottom of the arc plate 412 opens outward and contacts the clamping of the hammer head 409. The hammer head 409 falls to the surface of the baffle 406 under the action of gravity, thereby hammering the fifth threaded rod 407. In this reciprocating manner, the hammer box 405 and the electric telescopic rod 418 can adjust the height of the hammer box 405 and the length of the electric telescopic rod 418 according to the sinking distance of the fifth threaded rod 407, so that the arc plate 412 can always The hammer head 409 is clamped, and the staff makes the sampling time of the entire sampling device consistent, so that the number of hammering times can be kept consistent. The downward movement of the fifth threaded rod 407 can drive the fourth pulley 421 to rotate, and the rotation of the fourth pulley 421 can drive the second threaded cylinder 426 to rotate. The rotating second threaded cylinder 426 can make the seventh threaded rod 424 move upward, and thus the third piston plate 423 can move upward. The staff can judge the density of the sludge by the height of the third piston plate 423 inside the scale box 422.
