Description

Technical Field

[0001] This utility model relates to the field of engineering supervision technology, and in particular to an engineering supervision sampling device. Background Technology

[0002] Engineering supervision refers to a professional service activity in which a qualified supervision unit, entrusted by the client, monitors the construction of a project on behalf of the client, in accordance with the nationally approved project construction documents, relevant laws and regulations on engineering construction, engineering construction supervision contracts, and other engineering construction contracts. During the construction process, it is necessary to sample and analyze the soil at the construction site. Soil sample collection is the foundation of soil science research and geological exploration, providing a material basis for determining the physicochemical properties of soil samples.

[0003] Existing engineering supervision sampling devices cannot sample soil at specific depths during use. When it is necessary to collect soil at different depths, the sampling depth cannot be adjusted accurately according to the sampling requirements, making it difficult to meet actual needs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an engineering supervision sampling device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an engineering supervision sampling device, including a mounting column, a drill bit fixed at the bottom of the mounting column, a base plate threadedly connected to the mounting column and sleeved on the mounting column, a sliding groove is provided on the side wall of the mounting column, a sampling box is provided in the sliding groove and slidably connected to the inner wall of the sliding groove, and a driving component for driving the sampling box to move is installed on the mounting column.

[0006] By adopting the above technical solution, when it is necessary to sample soil at a specific depth, the staff rotates the base plate to move it to a suitable height, inserts the mounting post and ground nail into the soil until the bottom of the base plate contacts the ground, and then drives the sampling box to move and extend it from the chute opening to sample the soil. Then, the driving component drives the sampling box to fully enter the chute and removes the mounting post upwards, thereby taking out the soil sample. This allows for easy adjustment of the accurate sampling depth according to sampling needs.

[0007] Furthermore, the inner wall of the chute is provided with a moving groove and an installation groove. The driving assembly includes a rack fixed to the side wall of the sampling box and slidably connected to the inner wall of the moving groove, a vertical rod that is rotatably connected to the mounting column, a gear fixedly sleeved on the vertical rod and meshing with the rack, and a handwheel fixed to the upper end of the vertical rod. The lower end of the vertical rod is rotatably connected to the bottom wall of the installation groove.

[0008] By adopting the above technical solution, when it is necessary to move the sampling box, the staff drives the vertical rod and gear to rotate through the handwheel. Since the gear meshes with the rack and pinion, and the rack is fixed to the sampling box, the sampling box can be moved, which facilitates soil sampling.

[0009] Furthermore, a limiting groove is formed in the inner wall of the movable groove, and a limiting block is fixed to the side wall of the rack and slidably connected to the inner wall of the limiting groove.

[0010] By adopting the above technical solution, the limiting block and the limiting groove are slidably connected, which limits the movement range of the rack and the sampling box, preventing the sampling box from completely detaching from the groove and enhancing the stability of the sampling box.

[0011] Furthermore, a ground nail is fixed to the side wall of the sampling box near the chute opening, and the ground nail is a pyramid with its apex pointing away from the sampling box.

[0012] By adopting the above technical solution, the sampling box is drilled into the soil through ground nails during the movement, which makes it easier for staff to move the sampling box by driving the drive component and facilitates soil sampling.

[0013] Furthermore, a collection box is provided inside the sampling box.

[0014] By adopting the above technical solution, the collection box is placed inside the sampling box, and the collected soil falls into the collection box, making it convenient for staff to take out soil samples from the sampling box.

[0015] Furthermore, an upper magnetic block is embedded at the bottom of the collection box, and a lower magnetic block that is magnetically attracted to the upper magnetic block is embedded in the bottom wall of the sampling box.

[0016] By adopting the above technical solution, the upper and lower magnetic blocks are magnetically attracted to each other, thus adsorbing and fixing the collection box inside the sampling box, thereby enhancing the stability between the collection box and the sampling box.

[0017] Furthermore, an annular rubber sheet is fitted onto the mounting column, and the upper surface of the annular rubber sheet is fixed to the lower surface of the base plate.

[0018] By adopting the above technical solution, the annular rubber sheet is made of rubber material, and its surface has a large coefficient of friction. The base plate is pressed against the ground by the annular rubber sheet, which increases the friction between the base plate and the ground and enhances the stability of the sampling device. In addition, the annular rubber sheet also reduces the wear on the bottom of the base plate.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, when it is necessary to sample soil at a specific depth, the staff rotates the base plate to move it to a suitable height, inserts the mounting post and ground nail into the soil until the bottom of the base plate contacts the ground, and then drives the sampling box to move and extend it from the chute opening to sample the soil. Then, the staff drives the sampling box to fully enter the chute and removes the mounting post upwards to extract the soil sample, which makes it easy to adjust the accurate sampling depth according to the sampling needs.

[0021] 2. In this application, when it is necessary to move the sampling box, the staff drives the vertical rod and gear to rotate through the handwheel. Since the gear meshes with the rack and the rack is fixed to the sampling box, the sampling box can be moved, which facilitates soil sampling.

[0022] 3. In this application, the limiting block and the limiting groove are slidably connected, which limits the movement range of the rack and the sampling box, preventing the sampling box from completely detaching from the groove and enhancing the stability of the sampling box.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-4As shown in the figure, this application discloses an engineering supervision sampling device, including a mounting column 1, a drill bit 2, a base plate 3, a sampling box 4, and a driving assembly 5.

[0030] Mounting post 1 is a vertically positioned cylindrical structure. A sliding groove 11 is formed on the side wall of mounting post 1, and a moving groove 12 and a mounting groove 13 are formed on the inner wall of the sliding groove 11. Drill bit 2 is a cone-shaped structure with its apex pointing downwards, and it is fixed to the lower end of mounting post 1. Base plate 3 is a circular plate-shaped structure, fitted onto mounting post 1 and threadedly connected to it, with the axis of base plate 3 coinciding with the axis of mounting post 1. Sampling box 4 is a cuboid box-shaped structure, positioned within the sliding groove 11 and slidably connected to the inner wall of the sliding groove 11.

[0031] The drive assembly 5 is mounted on the mounting column 1 and is used to drive the sampling box 4 to move. The drive assembly 5 includes a rack 51, a vertical rod 52, a gear 53, and a handwheel 54. The rack 51 is horizontally arranged and fixed to the side wall of the sampling box 4. The vertical rod 52 is a vertically arranged round rod structure that passes through the mounting column 1 and is rotatably connected. The gear 53 is fixedly sleeved on the vertical rod 52 and meshes with the rack 51. The axis of the gear 53 coincides with the axis of the vertical rod 52. The handwheel 54 is fixed to the upper end of the vertical rod 52, and the axis of the handwheel 54 coincides with the axis of the vertical rod 52.

[0032] When soil sampling at a specific depth is required, the operator rotates the base plate 3 to move it to a suitable height, inserts the mounting post 1 and the ground nail 7 into the soil until the bottom of the base plate 3 contacts the ground, and then drives the vertical rod 52 and gear 53 to rotate by the handwheel 54. Since the gear 53 meshes with the rack 51 and the rack 51 is fixed to the sampling box 4, the sampling box 4 moves and extends out of the groove 11 to sample the soil. Then, by rotating the handwheel 54 in the opposite direction, the sampling box 4 is driven to fully enter the groove 11 and the mounting post 1 is taken out upwards, thereby taking out the soil sample. This allows for accurate adjustment of the sampling depth according to sampling needs.

[0033] To prevent the sampling box 4 from completely detaching from the slide groove 11, a limiting groove 14 is provided on the inner wall of the moving groove 12. A limiting block 6 is fixed on the side wall of the rack 51 and is slidably connected to the inner wall of the limiting groove 14. The limiting block 6 is slidably connected to the limiting groove 14, which limits the movement range of the rack 51 and the sampling box 4, thereby preventing the sampling box 4 from completely detaching from the slide groove 11 and enhancing the stability of the sampling box 4.

[0034] To facilitate soil sampling, a ground nail 7 is fixed to the side wall of the sampling box 4 near the opening of the chute 11. The ground nail 7 is a pyramid with its apex pointing away from the sampling box 4. During the movement of the sampling box 4, the ground nail 7 penetrates into the soil, making it easier for the staff to move the sampling box 4 by driving the drive component 5, thus facilitating soil sampling.

[0035] To facilitate the removal of soil samples, a collection box 8 is provided inside the sampling box 4. The collected soil falls into the collection box 8, making it easy for staff to remove the soil samples from the sampling box 4.

[0036] To enhance the stability between the collection box 8 and the sampling box 4, an upper magnetic block 81 is embedded at the bottom of the collection box 8, and a lower magnetic block 41 is embedded in the bottom wall of the sampling box 4, which is magnetically attracted to the upper magnetic block 81. The upper magnetic block 81 and the lower magnetic block 41 are magnetically attracted to each other, thus adsorbing and fixing the collection box 8 inside the sampling box 4, thereby enhancing the stability between the collection box 8 and the sampling box 4.

[0037] To enhance the stability of the sampling device, an annular rubber sheet 9 is fitted onto the mounting column 1. The upper surface of the annular rubber sheet 9 is fixed to the lower surface of the base plate 3. The annular rubber sheet 9 is made of rubber material and has a large coefficient of friction. The base plate 3 is pressed against the ground by the annular rubber sheet 9, which increases the friction between the base plate 3 and the ground, thereby enhancing the stability of the sampling device. In addition, the annular rubber sheet 9 also reduces the wear on the bottom of the base plate 3.

[0038] The working principle of the engineering supervision sampling device in this embodiment is as follows: When it is necessary to sample the soil at a specific depth, the staff rotates the base plate 3 to move it to a suitable height, inserts the mounting column 1 and the ground nail 7 into the soil until the bottom of the base plate 3 contacts the ground, and then drives the vertical rod 52 and the gear 53 to rotate by the handwheel 54. Since the gear 53 meshes with the rack 51 and the rack 51 is fixed to the sampling box 4, the sampling box 4 moves and extends out of the groove 11 to sample the soil. Then, by rotating the handwheel 54 in the opposite direction, the sampling box 4 is driven to fully enter the groove 11 and the mounting column 1 is taken out upward, thereby taking out the soil sample, which makes it easy to adjust the accurate sampling depth according to the sampling needs.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
