Description

Technical Field

[0001] The utility model relates to the technical field of geological survey of water conservancy projects, in particular to a device for measuring and taking underwater soft soil in geological survey of water conservancy projects. Background Art

[0002] The geological survey of water conservancy projects is the process of investigating, studying and evaluating the geological conditions at the construction site of the water conservancy project. In the geological survey of water conservancy projects, underwater soft soil measuring devices are usually used to sample the underwater soft soil so that the samples can be tested later.

[0003] The Chinese patent "A device for measuring underwater soft soil in geological survey of water conservancy projects" with the authorization announcement number "CN215296810U" uses a rubber extrusion head and a piston rod to achieve the suction of underwater soft soil by the measuring tube, thus achieving the soil suction effect.

[0004] However, the water flow rate will have a certain impact on the sampling quality. When the water flow rate in the bottom of the water is faster, the soft soil sample and water will mix more significantly, resulting in mixed sampling, which in turn affects the accuracy and completeness of the sampling position.

[0005] Therefore, a device for measuring underwater soft soil in geological survey of water conservancy engineering is proposed to solve the above problems. Utility Model Content

[0008] Preferably, the adjustment assembly includes a first screw rod rotatably connected to the inner wall of the survey pipe, the inner wall of the movable frame is threadedly connected to the surface of the first screw rod, and the top of the first screw rod is fixedly connected to a servo motor. The servo motor and the first screw rod are used to adjust the position of the protective cover, thereby ensuring that the conical block can be inserted into the soft soil at the bottom of the water, so that the protective cover can perform protective operations around the measuring pipe.

[0009] Preferably, the inner wall of the protective cover is fixedly connected with annularly distributed soil-breaking blocks, and the soil-breaking blocks are triangular in shape. The soil-breaking blocks are used to loosen the soft soil around the measuring tube, so that the measuring tube can be inserted into the underwater soft soil with less effort.

[0010] Preferably, a sliding block is fixedly connected to the surface of the survey tube, and a measuring frame is slidably connected to the surface of the sliding block.

[0011] Preferably, the top end of the measuring frame is fixedly connected to a second cylinder, and the bottom end of the second cylinder is fixedly connected to the top of the sliding block.

The second screw rod, the observation block, the second cylinder and the measuring frame are used to limit the downward movement range of the slider, so that the underwater soft soil measuring device for geological survey of water conservancy projects can accurately measure soft soil at different depths.

[0014] Preferably, the inner top wall of the survey tube is fixedly connected with a movable rod, and the inner wall of the movable frame is slidably connected to the surface of the movable rod. The movable rod is used to limit the movable frame's moving range, ensuring that the movable frame will not deviate during movement.

[0015] The beneficial effects of the utility model are:

[0016] 1. The protective cover and the conical block are used to protect the area around the measuring tube, thereby blocking the water flow in the bottom of the water from affecting the sampling effect of the measuring tube, improving the accuracy and integrity of the position of the samples taken by the underwater soft soil measuring device in the geological survey of water conservancy projects, and using the servo motor and the first screw rod to adjust the position of the protective cover, thereby ensuring that the conical block can be inserted into the underwater soft soil, so that the protective cover can perform protective operations around the measuring tube;

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When it is necessary to sample the underwater soft soil, the survey tube 1 moves down to a suitable position on the bottom of the water, and the servo motor 542 is started. The output shaft of the servo motor 542 rotates to drive the first screw rod 541 to rotate, and the first screw rod 541 rotates to drive the movable frame 51 to move down. The movable frame 51 moves down to drive the protective cover 52 to move down, and the protective cover 52 moves down to drive the conical block 53 to move down, so that the conical block 53 and the protective cover 52 are inserted into the soft soil, so that the protective cover 52 surrounds the measuring tube 4. At this time, the measuring tube 4 starts to sample the soft soil.

[0026] like Figure 2 As shown, the inner wall of the protective cover 52 is fixedly connected with an annularly distributed soil breaking block 543, and the shape of the soil breaking block 543 is triangular. The downward movement of the protective cover 52 drives the soil breaking block 543 to move downward, so that the soil breaking block 543 loosens the soft soil around the measuring pipe 4.

[0029] like Figure 3 As shown, the inner top wall of the survey pipe 1 is fixedly connected with a movable rod 549, and the inner wall of the movable frame 51 is slidably connected to the surface of the movable rod 549.

The lower end of the second cylinder 545 drives the survey tube 1 to move downward through the slider 546, so that the slider 546 abuts against the observation block 548, and then stops driving the survey tube 1 to move downward, so that the measuring tube 4 in the survey tube 1 can be inserted into the soft soil of the corresponding depth; the servo motor 542 is started, and the output shaft of the servo motor 542 rotates through the first screw rod 541 and the movable frame 51 to drive the protective cover 52 and the tapered block 53 to move downward, so that the tapered block 53 and the protective cover 52 are plugged into the soft soil, so that the protective cover 52 surrounds the measuring tube 4, and at this time the measuring tube 4 starts to sample the soft soil.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
