Description

Technical Field

[0001] The utility model relates to the field of sampling equipment, and more specifically, to a sampling device for soil detection in environmental protection engineering. Background Art

[0002] Environmental protection projects refer to projects specifically done for environmental protection. Due to environmental pollution caused by industrial development, these projects are based on a set of assumed goals, apply relevant scientific knowledge and technical means, and use the organized activities of a group of people to deal with and solve environmental pollution problems.

[0003] After searching, the existing patent (application number: 202220094737.4) discloses a soil sampling device for environmental protection engineering. The utility model relates to a soil sampling device for environmental protection engineering, including a sampling frame, a sampling mechanism and four positioning mechanisms. The four positioning mechanisms are respectively located on the left and right sides of the sampling frame, and the sampling mechanism is located below the sampling frame. The positioning mechanism includes a fixed screw block, and the inner side of the fixed screw block is threadedly connected with a movable screw rod. The bottom end of the movable screw rod is fixedly connected with a rolling bearing, and the bottom of the rolling bearing is fixedly connected with a positioning block. The bottom of the positioning block is fixedly connected with a positioning cone block. The top of the movable screw rod is fixedly connected with a manual rotating handle, the bottom of the sampling frame is fixedly connected with a moving wheel, and the left side of the sampling frame is fixedly connected with a fixed push handle.

[0004] In the process of realizing the utility model, the inventor discovered that the prior art had the following problems: although the above technical solution achieves the purpose of facilitating the positioning of the sampling device and preventing the sampling device from shaking or shifting during the sampling process by having the positioning cone block on the positioning block press against the ground, since the sampling mechanism and the positioning mechanism in the above technical solution are both arranged on the frame, and the frame itself cannot be flipped, folded and stored, adding the sampling mechanism and the positioning mechanism to the frame will greatly increase the volume of the entire device. The increased volume will not only occupy a larger storage space, but also be inconvenient for transportation.

[0005] Therefore, a foldable sampling device is proposed to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a sampling device for soil detection in environmental protection engineering to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling device for soil detection in environmental protection engineering, comprising a bottom plate, a placement groove is provided on the surface of the bottom plate, a rotating plate is rotatably connected to the inner wall of the placement groove, a support plate is fixedly connected to the top of the rotating plate, a sampling mechanism and a fixed positioning mechanism are respectively provided on the surface of the support plate, a circular hole is provided on the surface of the bottom plate, a clamping mechanism is provided on the inner wall of the circular hole, the clamping mechanism comprises a round rod slidably connected to the inner wall of the circular hole, an inclined block is fixedly connected to one end of the round rod, a clamping groove matched with the inclined block is provided on the surface of the support plate, and an extrusion spring for driving the inclined block to insert into the clamping groove is provided on the surface of the round rod.

[0014] Technical effects and advantages of the utility model:

[0015] Compared with the prior art, the sampling device for soil testing in environmental protection projects can flip and fold the support plate by setting a bottom plate, a placement slot, a support plate and a clamping mechanism.

DETAILED DESCRIPTION

[0022] 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.

[0023] As attached Figure 1-Figure 4 The sampling device for soil detection in environmental protection engineering shown in the figure includes a base plate 1, a pulley for convenient movement of the base plate 1 is arranged at the bottom of the base plate 1, a placement groove is opened on the surface of the base plate 1, a rotating plate 2 is rotatably connected to the inner wall of the placement groove, a fixing rod 18 is threadedly connected to the bottom of the base plate 1, a threaded hole compatible with the fixing rod 18 is opened on the lower surface of the rotating plate 2, and a support plate 3 is fixedly connected to the top of the rotating plate 2.

[0024] When taking samples, first move the entire device to the designated position, then flip the support plate 3 to the right so that the angle between the support plate 3 and the base plate 1 is ninety degrees to ensure that the support plate 3 is in a vertical state, and then rotate the fixing rod 18 at the bottom of the base plate 1. As the fixing rod 18 continues to move, it will eventually be screwed into the threaded hole on the rotating plate 2, thereby fixing the rotating plate 2 to prevent the support plate 3 from shifting during operation.

[0025] The surfaces of the support plate 3 are respectively provided with a sampling mechanism and a fixed positioning mechanism, a circular hole is opened on the surface of the base plate 1, and a clamping mechanism is arranged on the inner wall of the circular hole. The clamping mechanism comprises a round rod 4 slidably connected to the inner wall of the circular hole, and an inclined block 5 is fixedly connected to one end of the round rod 4. A clamping groove matched with the inclined block 5 is opened on the surface of the support plate 3, and an extrusion spring 6 for driving the inclined block 5 to be inserted into the inside of the clamping groove is arranged on the surface of the round rod 4.

[0026] After finishing the sampling work, first rotate the fixing rod 18 to make the fixing rod 18 disengage from the threaded hole on the rotating plate 2 to ensure that the rotating plate 2 can rotate normally, and then adjust the position of the sampling mechanism and the fixing positioning mechanism according to the actual situation. When the position is adjusted, flip the support plate 3 to the left, so that the support plate 3 enters the placement groove on the bottom plate 1. Since the surface of the round rod 4 is provided with an extrusion spring 6 that drives the inclined block 5 to be inserted into the inside of the clamping groove, the inclined block 5 will enter the clamping groove on the support plate 3 under the action of the elastic force of the extrusion spring 6. After entering the clamping groove, the inclined block 5 can limit the support plate 3 and prevent the support plate 3 from rotating. After completing the flipping and folding work, the volume of the entire equipment will be reduced, which is more conducive to the staff to transport and move the equipment.

[0027] The sampling device for soil detection in environmental protection projects is capable of flipping and folding the support plate 3 by providing a bottom plate 1, a placement slot, a support plate 3 and a clamping mechanism. This not only reduces the size of the entire device, but also does not occupy a large storage space when the device size becomes smaller. Moreover, the entire device is more convenient to transport after being folded.

[0028] The sampling mechanism includes a driving motor 7 fixedly mounted on the top of the supporting plate 3, the output shaft of the driving motor 7 is fixedly connected to a threaded rod 8, the surface of the threaded rod 8 is threadedly connected to a sliding block 9, a rotating motor 10 is fixedly mounted on the upper surface of the sliding block 9, the output shaft of the rotating motor 10 is fixedly mounted with a sampling barrel 11 by bolts, and the bottom of the sampling barrel 11 is threadedly connected to a sampling drill bit 12.

[0029] When the sampling mechanism is used, the driving motor 7 will drive the threaded rod 8 to rotate, and the rotating motor 10 will drive the sampling drill bit 12 on the sampling tube 11 to rotate. At this time, the rotating threaded rod 8 will drive the rotating sampling drill bit 12 to move toward the ground until the sampling tube 11 reaches a suitable sampling depth.

[0030] The fixed positioning mechanism includes a threaded column 13 and a limiting rod 14 fixedly installed on the inner wall of the support plate 3. The surface of the threaded column 13 is threadedly connected to a movable plate 15. The surface of the movable plate 15 is provided with a sliding groove adapted to the limiting rod 14. A triangular plate 16 is fixedly installed on the surface of the movable plate 15. Three positioning columns 17 are fixedly installed at the bottom of the triangular plate 16.

[0031] When the fixing mechanism is used, the triangular plate 16 on the movable plate 15 is moved downward by rotating the threaded column 13. Similarly, the three positioning columns 17 on the triangular plate 16 will also move toward the ground and eventually penetrate into the ground. Since the three positioning columns 17 on the triangular plate 16 are arranged at the three angles of the triangular plate 16, they will have strong stability, thereby preventing the sampling mechanism from being greatly offset during operation, and ensuring that the sampling work can be carried out normally.

[0032] The sampling device for soil detection in environmental protection projects is provided with a fixed positioning mechanism. Since the fixed positioning mechanism includes a triangular plate 16 and a positioning column 17, and the triangular plate 16 is in a triangular shape, the triangle has strong stability, so the fixed positioning mechanism can improve the stability of the sampling device during operation and avoid large-scale shaking and displacement during sampling.

[0033] The working process of the utility model is as follows: when using the sampling device for soil detection in environmental protection projects, first move the entire device to the designated position, then flip the support plate 3 to the right, so that the angle between the support plate 3 and the base plate 1 is ninety degrees to ensure that the support plate 3 is in a vertical state, and then rotate the fixing rod 18 at the bottom of the base plate 1. As the fixing rod 18 continues to move, it will eventually be screwed into the threaded hole on the rotating plate 2, so that the rotating plate 2 can be fixed to prevent the support plate 3 from being offset during operation.

[0034] When the support plate 3 is fixed, the triangular plate 16 on the movable plate 15 is moved downward by rotating the threaded column 13. Similarly, the three positioning columns 17 on the triangular plate 16 will also move toward the ground and eventually penetrate into the ground. Since the three positioning columns 17 on the triangular plate 16 are arranged at the three angles of the triangular plate 16, they will have strong stability, thereby preventing the sampling mechanism from being greatly offset during operation, ensuring that the sampling work can be carried out normally.

[0035] During the final sampling, the driving motor 7 will drive the threaded rod 8 to rotate, and the rotating motor 10 will drive the sampling drill bit 12 on the sampling tube 11 to rotate. At this time, the rotating threaded rod 8 will drive the rotating sampling drill bit 12 to move toward the ground until the sampling tube 11 reaches a suitable sampling depth.

[0036] This is the working principle of the sampling device for soil testing in this environmental protection project.

[0037] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal connectivity between two components, or direct connection.
