[0039] The working principle of the present invention is as follows: the external lifting device drives the support base 101 to move through the hook 102, and the support base 101 drives the support box 103 to move, and then the whole is lifted into the river channel where sampling is required.
[0040] When the position adjustment component and the connecting unit are working: the output shaft of the motor 201 drives the position adjustment plate 202 to rotate, and when the position adjustment plate 202 rotates, it drives the connecting shaft 306 to slide through the arc groove 204, and the connecting shaft 306 drives the connecting shaft 2 304 to slide in the slide groove 205, and the connecting shaft 2 304 drives the connecting shaft 2 304 to move through the connecting shaft 2 304, and the connecting frame 302 drives the sampling component to move, thereby adjusting the spacing between the multiple sampling components, so as to facilitate the sampling of sludge in different ranges in the river channel. It has a wide range of applications and is convenient to adjust, which greatly improves the efficiency of sludge sampling and saves the time for adjusting the sampling components.
[0041] When the sampling unit is working: the output shaft of the motor 2 406 drives the screw 404 to rotate, and when the screw 404 rotates, it drives the sliding frame 405 to slide downward on the sampling tube 1 401, and the sliding frame 405 drives the power mechanism to move downward through the support rod 403, and the power mechanism drives the opening and closing mechanism and the sampling tube 2 407 to move downward, so that the sampling tube 2 407 is moved out of the sampling tube 1 401, and under the action of the sampling teeth 505, the power mechanism, the opening and closing mechanism and the sampling tube 2 407 are inserted into the silt in the river channel, so that the silt enters the sampling tube 2 407, and by setting a plurality of sampling teeth 505, the motor 2 406 and the screw 404, the sampling tube 2 407, the power mechanism and the opening and closing mechanism can be quickly and efficiently inserted into the silt in the river channel, so as to improve the efficiency of silt sampling.
[0042] When the power mechanism and the opening and closing mechanism are working: the output shaft of the motor three 506 drives the gear 507 to rotate through the rotating shaft 512, the gear 507 drives the gear ring 508 to rotate, the gear ring 508 drives the rotating ring 509 to rotate, the rotating ring 509 drives the connecting pin 511 to slide through the arc groove 2 510, the connecting pin 511 drives the slider 515 to slide in the slide groove 2 514 through the opening and closing plate 504, and then adjusts the spacing between the multiple opening and closing plates 504. After the sampling is completed, the multiple opening and closing plates 504 are close to each other, and the lower end of the sampling tube 2 407 is blocked by the multiple opening and closing plates 504, so as to separate the silt entering the sampling tube 2 407 after sampling from the silt in the river channel, and at the same time, it can prevent the silt entering the sampling tube 2 407 from sliding into the river channel under the action of gravity when the whole is moved out of the river channel, thereby improving the effect of silt sampling.
[0043] When the pushing unit is working: after the sampling is completed, the whole is moved out of the river channel to the position of the sludge collection device through the external lifting device, so that the multiple opening and closing plates 504 are separated from each other (the working principle is opposite to that when they are close to each other), and the lower end of the sampling tube 407 is exposed. The output shaft of the motor 406 drives the screw 404 to rotate in the opposite direction. When the screw 404 rotates, it drives the sliding frame 405 to slide upward on the sampling tube 1 401. The sliding frame 405 drives the power mechanism to move upward through the support rod 403. The power mechanism drives the opening and closing mechanism and the sampling tube 2 407 to move upward, thereby moving the sampling tube 2 407 into the sampling tube 1 401. At this time, under the action of the pushing plate 602, the sample in the sampling tube 2 407 is The sludge is pushed out into the sludge collecting device, and the moving distance of the sampling tube 407 is recorded by the electronic scale 603. When the specified distance (i.e. the sampling depth) is reached, the multiple opening and closing plates 504 are brought close to each other to cut off the sludge, and then the position of the sludge collecting device is adjusted to collect the sludge at the next depth, so that the sludge at different depths can be classified and collected, so as to facilitate the subsequent classification and detection of the sludge at different depths. When the sampling tube 407 completely enters the sampling tube 1 401, the sludge sampled in the sampling tube 407 is completely pushed out by the pushing plate 602, thereby improving the efficiency of sludge separation and further improving the overall sampling efficiency.
