[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but the embodiments should not be construed as limiting the present invention.

[0020] The utility model provides a simple device for measuring and sampling the thickness of rotary pile sediment. Figure 1-4 The utility model comprises a base 1, a fixed box 2 and an insertion rod 3, a closed cavity is provided on one side of the insertion rod 3, and first slide grooves 4 are provided on the opposite sides of the cavity, and first sliders 5 are slidably connected to the inside of the two first slide grooves 4, and the first sliders 5 can move through the first slide grooves 4, and a collecting box 6 is fixedly connected between the opposite surfaces of the two first sliders 5, and the collecting box 6 can be disassembled through the first slider 5. A tilting block (not marked in the figure) is provided on one side of the top of the collecting box 6. After the insertion rod 3 touches the bottom of the sediment, the device is pulled upward as a whole. When the device rises, the tilting block on the collecting box 6 will contact the sediment. When the device rises, the sediment is scraped off by the tilting block and falls into the collecting box 6 for collection. Then, the height of the bottom base 1 is subtracted from the scale pointed to by the third slider 13, so as to calculate the thickness of the sediment, and then the collecting box 6 is disassembled through the first slider 5, thereby realizing the measurement and sampling of the sediment thickness.

[0021] like Figure 5As shown, a servo motor 7 is fixedly connected to one side of the top of the fixed box 2, and a lead screw 8 is rotatably connected to one side of the fixed box 2 near the plug rod 3. The top of the lead screw 8 passes through the fixed box 2 and is fixedly connected to the output end of the servo motor 7, and the lead screw 8 is driven to rotate by the servo motor 7. A second slide groove 9 is provided on the inner wall of the fixed box 2 near the lead screw 8, and a second slider 10 is slidably connected inside the second slide groove 9 and on the surface of the lead screw 8. The second slider 10 can move through the second slide groove 9, and the second slider 10 is threadedly connected to the lead screw 8. The second slider 10 is fixedly connected to the plug rod 3 on the side away from the second slide groove 9. A pressure sensor (not marked in the figure) is provided on the plug rod 3, and the pressure sensor is connected to the servo motor 7 through an electric wire. A first rack 11 is fixedly connected to the side of the plug rod 3 away from the second slider 10, and a third slide groove 12 is provided on the inner wall of the fixed box 2 away from the second slide groove 9. A groove is provided on the outer wall of the fixed box 2 near the third slide groove 12. A scale line (not marked in the figure) is set on the side, and the groove is connected to the third slide groove 12. A third slider 13 is slidably connected inside the third slide groove 12 and between the grooves. The third slider 13 can move through the third slide groove 12. The third slider 13 is fixedly connected to the second rack 14 on the side close to the first rack 11. A gear 15 is rotatably connected to the inside of the fixed box 2 and between the first rack 11 and the second rack 14 by an axis. The gear 15 is meshed with the first rack 11 and the second rack 14. When in use, the device is placed on the top of the sediment, and then the servo motor 7 is started to drive the lead screw 8 to rotate, so that the second slider 10 drives the insertion rod 3 to descend. When the insertion rod 3 descends, the gear 15 is rotated through the first rack 11. When the gear 15 rotates, the second rack 14 is moved upward and kept stable by the third slider 13, so that the insertion rod 3 can be inserted into the bottom of the sediment. After the insertion rod 3 contacts the bottom of the sediment, the servo motor 7 is controlled to stop working by the pressure sensor.

[0022] like Figure 6 As shown, a movable groove is provided at the top of the base 1 and below the fixed box 2, and the bottom end of one side of the fixed box 2 is connected to the box door 16 by a hinge. By opening the box door 16, the collection box 6 can be easily replaced and installed and disassembled, and a "U"-shaped limit frame 17 is fixedly connected to the other side of the fixed box 2. A Z-shaped member 18 is slidably connected inside the "U"-shaped limit frame 17 and between the movable grooves. By pulling the Z-shaped member 18 backward, the bottom of the Z-shaped member 18 moves backward from the movable groove, so that the insertion rod 3 can be lifted and lowered from the movable groove.

[0023] Working principle: When in use, the device is placed on the top of the sediment, and the Z-shaped member 18 is pulled backward so that the bottom of the Z-shaped member 18 moves backward from the moving groove, and then the servo motor 7 is started to drive the lead screw 8 to rotate, so that the second slider 10 drives the insertion rod 3 to descend, and the gear 15 is rotated through the first rack 11 while the insertion rod 3 descends. While the gear 15 rotates, the second rack 14 moves upward and is kept stable by the third slider 13, so that the insertion rod 3 can be inserted into the bottom of the sediment. After the insertion rod 3 contacts the bottom of the sediment, the servo motor 7 is controlled to stop working by the pressure sensor, and the device is pulled upward as a whole. When the device rises, the tilting block on the collection box 6 will contact the sediment, and the sediment will be scraped off by the tilting block and fall into the collection box 6 for collection during the rise, and then the height of the bottom base 1 is subtracted from the scale pointed by the third slider 13, thereby calculating the thickness of the sediment, and then the collection box 6 is disassembled through the first slider 5, thereby realizing the measurement and sampling of the sediment thickness.
