[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1-3 As shown, the present embodiment discloses a sample anti-slip device for a large-caliber sediment sampler, comprising an anti-slip fixing plate 1, an insert plate guide plate 6, an insert plate 2, and a driving module, wherein the driving module is installed in the insert plate guide plate, the driving shaft of the driving module extends to one side of the insert plate guide plate and is fixedly connected to the wheel axle 8, the insert plate 2 is located in the insert plate guide plate and is driven to move forward and backward by the driving module, an anti-slip fixing plate is fixedly provided on the side of the insert plate guide plate away from the driving shaft, a groove 9 for the insert plate to pass through is provided on the anti-slip fixing plate, a limiting slot-shaped hole 7 is also provided on the anti-slip fixing plate, and the limiting slot-shaped hole is an elliptical waist-shaped hole.

[0019] In this embodiment, the anti-dropping fixing plate is semicircular and is installed at the sampling tube joint when working.

[0020] The driving module includes a driving shaft, a gear set 5, and a linear motion transmission mechanism. The linear motion transmission mechanism is fixedly connected to one end of the plug plate to drive the plug plate to move back and forth. The gear set includes a driving gear and a driven gear. The driving gear is meshed with the driven gear. The diameter of the driving gear is smaller than that of the driven gear. The driving shaft is fixedly connected to the central axis of the driving gear, and the central axis of the driven gear is fixedly connected to the linear motion transmission mechanism.

[0021] In this embodiment, the linear motion transmission mechanism is a screw-sleeve matching structure, including a screw and a screw sleeve. One end of the screw 3 is fixedly connected to the central axis of the driven gear. The screw sleeve 4 is sleeved on the screw and can move back and forth along the screw. The screw sleeve is fixedly connected to one end of the plug plate.

[0022] The purpose of the linear motion transmission mechanism is to convert the rotational motion of the wheel axle into linear motion, thereby driving the plug board to move forward and backward. All structures that can achieve this purpose belong to the protection scope of this utility model.

[0023] After the sediment sampler is recovered on board, the sampling tube needs to be separated. The purpose of the anti-slip device in this embodiment is to divide the sample into sections. The circular edge of the plug plate is chamfered to reduce the resistance during cutting. After segmentation, it can also prevent the sample in the sampling tube from falling when the sampling tube is lifted and separated. Therefore, the shape and size of the plug plate are adapted to the shape and size of the sampling tube, so that the plug plate covers the cross-section of the sampling tube.

[0024] The use and installation of the utility model is as follows Figure 4 As shown, after the sediment sampler takes samples, when the sampling tube 10 is vertically hoisted to the deck unit, the upper and lower sampling tubes need to be separated. At this time, the anti-slip device 11 of this embodiment is installed at the sampling tube joint, specifically: the anti-slip fixing plate is installed on the outside of the joint at the lower end of the upper sampling tube, the limiting slot hole is aligned with the bolt hole on the sampling tube, the anti-slip fixing plate is fixed with bolts, and the wheel axle is rotated with an electric drill or wrench. The rotation of the wheel axle drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the lead screw to rotate, the thread sleeve slides back and forth along the lead screw, and at the same time drives the plug plate to extend from the groove. After the plug plate cuts off the samples in the upper and lower sampling tubes, the bottom of the sampling tube is covered. At this time, the hoisting of the sampling tube effectively prevents the sample from falling out of the sampling tube. The structure of the utility model is designed for a large-diameter sediment sampler. The diameter of the large-diameter sediment sampler exceeds 200 mm, so inserting the plug plate may be more laborious. Through the gear set, the diameter of the driving gear is smaller than the diameter of the driven gear. When the wheel shaft is rotated by external force to push the plug plate to move, the extrusion force during the insertion and material distribution process is increased to achieve a labor-saving effect.

[0025] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
