[0021] The technical scheme of the utility model will be further described in conjunction with the drawings of the utility model embodiments. The utility model is not limited to the following specific embodiments. It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] As shown in the figure, the water ecological management sampling device comprises a sampling mechanism, a driving mechanism and a mounting mechanism. Figs. 1 to 3 The sampling mechanism comprises a sampling cylinder and a sampling pipe 200. The sampling cylinder comprises a main pipe 110 and two branch pipes 120. One end of the main pipe 110 is connected to the two branch pipes 120 respectively. One end of the sampling pipe 200 is connected to one of the branch pipes 120, and the other end is connected to the other branch pipe 120. The mounting mechanism is arranged at the end of the main pipe 110 away from the two branch pipes 120. The driving mechanism is partially arranged on the mounting mechanism and partially arranged inside the sampling cylinder.

[0023] Specifically, the main pipe 110 is provided with a sealing cover 300 away from one end of the two branch pipes 120, and the mounting mechanism is arranged on the sealing cover 300. The mounting mechanism comprises a fixing pipe 410 and two handles 420, the fixing pipe 410 is arranged on the sealing cover 300, one handle 420 is arranged at one end of the fixing pipe 410, and the other handle 420 is arranged at the other end of the fixing pipe 410. The sealing cover 300 is provided with a through hole 301, and the main pipe 110 communicates with the fixing pipe 410 through the through hole 301. The driving mechanism comprises a driving motor 510, a lead screw 520, a sliding block 530, two connecting assemblies and two samplers, the driving motor 510 is arranged on the fixing pipe 410, the lead screw 520 is arranged in the main pipe 110, the output shaft of the driving motor 510 is connected to the lead screw 520 after penetrating through the fixing pipe 410 and the through hole 301, and the sliding block 530 is slidingly arranged on the lead screw 520. One end of each connecting assembly is rotatably connected to the sliding block 530, and the other end is connected to one sampler. Each connecting assembly comprises a connecting rod 541, a limiting block 542 and a mounting rod 543, one end of each connecting rod 541 is rotatably connected to the sliding block 530, the other end is connected to the limiting block 542, and one end of each mounting rod 543 is arranged on the side of the limiting block 542 away from the connecting rod 541, and the other end is connected to the sampler. The inner side wall of each branch pipe 120 is provided with a track 121, and each limiting block 542 is slidingly arranged on the track 121. An inclined block 122 is arranged on the inner side wall of each branch pipe 120, and each inclined block 122 is in movable abutment with one sampler. Each sampler is a sampling box 600, and an elastic plate 610 is arranged on the side wall of each sampling box 600. Each elastic plate 610 is in movable abutment with one inclined block 122. One end of the sampling pipe 200 is detachably connected to one branch pipe 120, the other end is detachably connected to the other branch pipe 120, and the sampling pipe 200 movably communicates with the two branch pipes 120.

[0024] In the initial state, each sampling box 600 covers a branch pipe 120, and at this time, the elastic plate 610 on each sampling box 600 is in abutment and extrusion and contraction by the inclined block 122 on the branch pipe 120.

[0025] When the water ecological management sampling device is needed to sample the sludge, the two branch pipes 120 are inserted into the sludge, the driving motor 510 is started, the output shaft of the driving motor 510 rotates to drive the screw rod 520 to rotate, and then drives the sliding block 530 to slide downwards, at this time the sliding block 530 drives the two connecting rods 541 to move, and further, each connecting rod 541 is rotationally connected with a limiting block 542. Since each limiting block 542 is slidably arranged on a guide rail, when the connecting rod 541 pushes the limiting block 542, the limiting block 542 can only move along the guide rail. Then the mounting rod 543 is driven to move, that is, the mounting rod 543 pushes the sampling box 600 away from the branch pipe 120, and finally the whole sampling box 600 is pushed into the sludge. Since the inclined block 122 does not abut against the elastic plate 610 during the movement, the elastic plate 610 is not subjected to the extrusion force and can recover to the normal state, at this time the whole sampling box 600 can load the sludge therein. After sampling, the output shaft of the driving motor 510 reverses to drive the screw rod 520 to rotate, and then drives the sliding block 530 to slide upwards, at this time the sliding block 530 drives the two connecting rods 541 to move, that is, the two limiting blocks 542 are pulled back through the two connecting rods 541, the limiting block 542 drives the sampling box 600 after sampling to move towards the branch pipe 120 through the mounting rod 543, and finally the sampling box 600 covers the branch pipe 120, and the inclined block 122 abuts against the elastic plate 610 again. Since the inclined block 122 extrudes the elastic plate 610, a gap is formed, so that the sampled sludge can flow out along the gap. Since the gap is located at one side of the sampling pipe 200, the sludge flowing out can flow into the sampling pipe 200, that is, from both ends into the sampling pipe 200.

[0026] After sampling, the two branch pipes 120 are extracted from the sludge, and then the sampling pipe 200 is disassembled, and the sampled sludge can be obtained. The water ecological management sampling device is easy to operate, the sampled sludge can directly flow into the sampling pipe 200, and the problem of sludge flowing out can be well avoided during the whole sampling process, and the practicality is high.

[0027] In summary, the above-mentioned embodiments are not limiting embodiments of the present application, and any modification or equivalent deformation made by those skilled in the art on the basis of the essential content of the present application is within the technical scope of the present application.
