Description

Technical Field

[0001] This utility model relates to the field of soil pollution remediation, specifically to a sampling device for soil pollution remediation. Background Technology

[0002] With people's increasing awareness of environmental protection, soil remediation has become a top priority in current environmental protection tasks. In the early stages of soil remediation, environmental assessment units need to evaluate the degree of pollution of the soil to be remediated, which requires the use of sampling devices.

[0003] Currently, most soil sampling devices require staff to hold the soil at a designated location for sampling. If the soil is hard, they have to press it down or soak it in water to soften it. This results in low sampling efficiency and makes it difficult to perform solid-liquid separation after the sample is collected, reducing its practicality. In addition, it is inconvenient to move the device. Based on the above problems, this utility model provides a sampling device for soil pollution remediation. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for soil pollution remediation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for soil pollution remediation, comprising,

[0006] The protective box has perforations at the bottom of its inner wall.

[0007] A sampling mechanism is installed inside a protective box for loosening and sampling the soil. The sampling mechanism includes a threaded rod rotatably mounted on the inner side of the inner top wall of the protective box. A stepper motor is fixedly mounted on the top of the protective box, and the output end of the stepper motor is fixedly connected to the top of the threaded rod. A threaded sleeve is threadedly mounted on the outer surface of the threaded rod, and a drill bit is provided at the bottom end of the threaded sleeve. A fixing rod is fixedly mounted inside the protective box, and a sliding ring is slidably mounted on the surface of the fixing rod. The left end of the sliding ring is fixedly connected to the right side surface of the threaded sleeve.

[0008] A cylinder is fixedly installed on the inner side of the inner top wall of the protective box, on the left side of the threaded rod. A connecting post two is fixedly connected to the output end of the cylinder. A connecting post one of the same size as the connecting post two is detachably installed at the bottom end of the connecting post two. A fixing ring is provided in the middle of the outer surface of the connecting post one and the connecting post two. Fixing blocks are fixedly connected to both ends of the fixing ring. A fixing pin is screwed into the internal thread of one of the fixing blocks. A round hole for cooperating with the fixing pin is opened in the internal part of the other fixing block. A sampling tube is fixedly installed at the bottom end of the connecting post one. The drill bit and the sampling tube are both located directly above the through hole.

[0009] Furthermore, an electric telescopic rod is fixedly installed on the inner top wall of the protective box away from the cylinder. A push plate is fixedly connected to the output end of the electric telescopic rod. Three evenly distributed extrusion blocks are fixedly installed at the bottom end of the push plate. An installation plate is fixedly installed on the bottom of the inner wall of the protective box. Three evenly distributed positioning frames are fixedly connected to the upper surface of the threaded sleeve. A collection tank is set inside the positioning frame. A filter screen is fixedly set inside the collection tank. The extrusion blocks are vertically aligned with the collection tank. A leakage groove is opened on the upper surface of the installation plate below the three collection tanks. A liquid collection tank is set on the top of the installation plate away from the sliding ring.

[0010] Furthermore, the lower surface of the protective box is fixedly equipped with brackets on all four sides. The brackets are detachably equipped with casters. Bolts are threaded on the left side of the brackets. Two vertically corresponding screw holes are opened on both the left and right sides of the brackets. The bolts pass through the brackets and the casters and are threaded into the screw holes.

[0011] Furthermore, a protective cover is provided on the top of the protective box outside the stepper motor.

[0012] Furthermore, the front side of the protective box is hinged with two symmetrically distributed doors.

[0013] Furthermore, a handle is fixedly installed on the left side wall of the protective box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Before the staff takes samples, the entire device is fixed in the designated position. The stepper motor is started to drive the threaded rod to rotate. Due to the limiting effect of the sliding ring, the threaded sleeve on the threaded rod will move the bottom drill bit downward to loosen the soil. This can improve the sampling efficiency to a certain extent. After loosening the soil, the cylinder is started to drive the bottom sampling tube downward. The soil in the soil will be squeezed into the inside of the sampling tube. Then the cylinder is started again to bring the sampling tube back. The staff can unscrew the fixing pin to carry out subsequent operations on the soil inside the sampling tube, which improves the practicality of the entire device.

[0016] 2. After removing the sampling tube, pour the soil inside the sampling tube into the collection tank. When the soil in the three collection tanks is about equal, start the electric telescopic rod to push the three squeezing blocks below to squeeze the soil inside the collection tank. This will separate the solid and liquid of the sample. The solid will remain inside the collection tank, and the liquid will flow into the liquid collection tank through the trough. This will facilitate subsequent research by the staff and improve the practicality of the overall device.

[0017] 3. When the staff is taking soil samples, pull out the bolts and install the casters inside the fixed brackets with the bolts. Screw the bolts into the screw holes at the top. The four fixed brackets will improve the stability of the protective box during sampling. When it is necessary to move the protective box, unscrew the bolts and lower the casters outside the fixed brackets. Screw the bolts through the threads of the casters into the screw holes at the bottom to move the protective box. Attached Figure Description

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

[0024] Example 1: Please refer to Figures 1-4 A sampling device for soil pollution remediation, comprising,

[0025] The protective box 1 has a through hole 23 at the bottom of its inner wall, which provides conditions for loosening the soil and taking samples.

[0026] Sampling mechanism 24 is installed inside the protective box 1 and is used to loosen the soil and take samples. Sampling mechanism 24 includes a threaded rod 18 rotatably installed on the inner side of the inner top wall of the protective box 1. A stepper motor 17 is fixedly installed on the top of the protective box 1. The output end of the stepper motor 17 is fixedly connected to the top of the threaded rod 18. A threaded sleeve 21 is threadedly installed on the outer surface of the threaded rod 18. A drill bit 22 is provided at the bottom end of the threaded sleeve 21. A fixing rod 20 is fixedly installed inside the protective box 1. A sliding ring 19 is slidably sleeved on the surface of the fixing rod 20. The left end of the sliding ring 19 is fixedly connected to the right side surface of the threaded sleeve 21.

[0027] Based on the above features, before the staff takes samples, the entire device is fixed in the designated position, the stepper motor 17 is started, and the threaded rod 18 is driven to rotate. Because of the limiting effect of the sliding ring 19, the threaded sleeve 21, which is threaded on the threaded rod 18, will move downward with the bottom drill bit 22 to loosen the soil first, which can improve the sampling efficiency to a certain extent.

[0028] A cylinder 16 is fixedly installed on the inner side of the inner top wall of the protective box 1, on the left side of the threaded rod 18. The output end of the cylinder 16 is fixedly connected to a connecting post 2 15. A connecting post 10 of the same size as the connecting post 2 15 is detachably installed at the bottom end of the connecting post 2 15. A fixing ring 8 is provided in the middle of the outer surface of the connecting post 10 and the connecting post 2 15. Fixing blocks 12 are fixedly connected to both ends of the fixing ring 8. A fixing pin 11 is screwed into the internal thread of one fixing block 12. A round hole 32 that mates with the fixing pin 11 is opened in the internal part of the other fixing block 12. A sampling tube 9 is fixedly installed at the bottom end of the connecting post 10. The drill bit 22 and the sampling tube 9 are both located directly above the through hole 23.

[0029] Based on the above features, after loosening the soil, the cylinder 16 is activated, which moves the sampling tube 9 at the bottom downwards. The soil in the soil is squeezed and enters the interior of the sampling tube 9. Then, the cylinder 16 is activated again to bring the sampling tube 9 back. The operator can unscrew the fixing pin 11 to perform subsequent operations on the soil inside the sampling tube 9, which improves the practicality of the overall device.

[0030] In this embodiment, an electric telescopic rod 14 is fixedly installed on the inner top wall of the protective box 1 away from the cylinder 16. A push plate 31 is fixedly connected to the output end of the electric telescopic rod 14. Three evenly distributed extrusion blocks 30 are fixedly installed at the bottom end of the push plate 31. An installation plate 27 is fixedly installed at the bottom of the inner wall of the protective box 1. Three evenly distributed positioning frames 28 are fixedly connected to the upper surface of the threaded sleeve 21. A collection tank 29 is provided inside the positioning frame 28. A filter screen is fixedly provided inside the collection tank 29. The extrusion blocks 30 are vertically aligned with the collection tank 29. A leakage groove 26 is provided on the upper surface of the installation plate 27 below the three collection tanks 29. A liquid collection tank 25 is provided on the top side of the installation plate 27 away from the sliding ring 19.

[0031] Based on the above features, after removing the sampling tube 9, the soil inside the sampling tube 9 is poured into the collection tank 29. When the soil inside the three collection tanks 29 is approximately equal, the electric telescopic rod 14 is activated to push the three squeezing blocks 30 below to squeeze the soil inside the collection tank 29, thereby separating the solid and liquid of the sample. The solid remains inside the collection tank 29, and the liquid flows into the liquid collection tank 25 along the trough 26, which facilitates subsequent research by the staff and improves the practicality of the overall device.

[0032] Furthermore, a protective cover 7 is provided on the top of the protective box 1 outside the stepper motor 17, which can protect the stepper motor 17 inside.

[0033] Furthermore, the front of the protective box 1 is hinged with two symmetrically distributed doors 2, which facilitate the opening of the protective box 1 by staff when needed.

[0034] Example 2: Please refer to Figure 1 A sampling device for soil pollution remediation, which differs from Embodiment 1, is provided with a fixed bracket 3 fixedly installed on all four sides of the lower surface of the protective box 1. A universal wheel 5 is detachably installed inside the fixed bracket 3. A bolt 4 is threaded on the left side of the fixed bracket 3. Two vertically corresponding screw holes 6 are opened on both the left and right sides of the fixed bracket 3. The bolt 4 passes through the fixed bracket 3 and the universal wheel 5 and is threaded in the screw hole 6.

[0035] Based on the above features, when the staff takes soil samples, the bolt 4 is pulled out, the caster 5 is installed inside the fixed bracket 3 through the bolt 4, and the bolt 4 is screwed into the upper screw hole 6. The stability of the protective box 1 during sampling can be improved by the four fixed brackets 3. When it is necessary to move the protective box 1, the bolt 4 is unscrewed, the caster 5 is lowered out of the fixed bracket 3, and the bolt 4 is threaded through the caster 5 and screwed into the lower screw hole 6, so that the protective box 1 can be moved, which improves the practicality of the overall device.

[0036] Furthermore, a handle 13 is fixedly installed on the left side wall of the protective box 1, which allows staff to move the protective box 1 more conveniently.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
