Description

Technical Field

[0001] The invention relates to the technical field of geological monitoring sampling, in particular to a soil sampler for geological monitoring. Background Art

[0002] The soil sampler for geological monitoring is an application tool used for monitoring the soil composition under the surface. The existing general sampler uses a soil drilling device to break the hard soil base and gravel base on the surface, and then uses the soil drilling equipment to form holes at the location to be sampled on the surface. The holes are reserved to facilitate the subsequent penetration of sampling equipment. The soil at the location to be tested is taken out using a sampling tube that penetrates deep into the ground to complete the sampling operation.

[0003] Existing soil samplers, such as sampling equipment that uses a drill to break the soil, have limitations when used. For example, they can complete rapid sampling operations during conventional soil sampling, but they are not suitable for semi-fluid soil and mixed materials under the surface.

[0004] Or in order to improve the efficiency of breaking the semi-rock base, drilling equipment with dust reduction and cooling water is added when drilling the foundation stone. After the surface soil base is broken, the soil at the deep drilling formation is in a semi-fluid liquid mixed state. During sampling, the semi-fluid mixed state of the soil will form a large damping external force. When the sampling equipment goes deeper, the damping external force reaction affects the penetration of the sampling equipment; and at the same time, under the action of gravity, the semi-fluid soil is deposited downward, and the upper soil will continue to accumulate downward, affecting the sampling accuracy of the lower soil, affecting the efficiency of soil sampling and the accuracy of subsequent soil geological testing.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original soil sampler for geological monitoring. Summary of the invention

[0006] The purpose of the present invention is to provide a soil sampler for geological monitoring to solve the problem that the existing soil sampler for geological monitoring has a single function and is affected by the properties of the geological soil used and the low efficiency of the soil sampler during drilling.

[0007] To achieve the above object, the present invention provides the following technical solution: a soil sampler for geological monitoring, comprising:

[0008] A positioning member, wherein the sampling tube is fixed through the middle, a rotating assembly is installed on the outer wall of the upper end of the sampling tube through an elastic telescopic rod, and a sampling cone rod is fixed on the output shaft end of the rotating assembly;

[0009] It also includes: a sampling cone rod, which is coaxially arranged with the sampling tube, and the left and right sides of the sampling tube are provided with inclined plates, and a connecting rod is fixed between the inclined plates on both sides, and the upper end of the connecting rod is connected to the electromagnetic controller on the outer wall of the upper end of the sampling tube;

[0010] The electromagnetic controller controls the connection rods on the left and right sides of the sampling tube to rise and fall synchronously in different directions.

[0011] Preferably, the upper and lower ends of the elastic telescopic rod are respectively hingedly rotatably arranged with the bottom shell of the rotating assembly and the upper outer wall of the sampling tube, wherein the elastic telescopic rod is evenly distributed at equal angles.

[0013] The electromagnetic combiner includes an electromagnet and a permanent magnet.

[0014] Preferably, the lower end of the sampling cone rod is a spiral cone, and the outer wall of the upper section is a smooth round rod;

[0015] The maximum outer diameter of the spiral cone at the lower end of the sampling cone rod is equal to the outer diameter of the sampling tube, and the sampling cone rod and the sampling tube form a relative lifting structure.

[0016] Preferably, the inclined plates are arranged in two groups on the left and right sides of the interior of the sampling tube, the inclined plates in each group are parallel to each other and inclined, and the inclined plates between the two groups are staggered in the horizontal plane.

[0017] Preferably, the arc-shaped outer wall of the inclined plate is in contact with the inner wall of the sampling tube, and the middle part of the inclined plate is in a through-type fitting and sliding connection with the outer wall of the smooth round rod of the upper section of the sampling cone rod, and a feeding port for sampling and feeding is provided at the top of the sampling tube;

[0018] The inclined plate shortens the upper cantilever arm of the sampling cone rod.

[0019] Preferably, the uppermost inclined plate inside the sampling tube is tilted toward the discharge port, wherein an elastic rubber film is provided at the bottom of the straight edge of the inclined plate inside the sampling tube.

[0020] Preferably, the electromagnetic controller is a magnetic lifting component controlled by an electromagnet, which uses magnetic repulsion and attraction to control the lifting movement of the connecting rod and the inclined plate.

[0021] Preferably, the positioning member is installed in a through-type manner on the positioning bracket, wherein the positioning bracket is provided with a hydraulic pushing component for pushing the positioning member to rise and fall, and the positioning bracket is provided with a hydraulic pressurizing component connected to the hydraulic pushing component.

When the soil drilling is completed, the accumulated soil on the inclined plate can also be pushed down without affecting the synchronous lifting and lowering operation of the connecting rod in different directions.

DETAILED DESCRIPTION

[0038] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 4-Figure 9 The present invention provides a technical solution: a soil sampler for geological monitoring, comprising:

[0040] The positioning member 1 has a fixed sampling tube 2 through the middle thereof, and a rotating assembly 3 is installed on the outer wall of the upper end of the sampling tube 2 through an elastic telescopic rod 4, and a sampling cone rod 5 is fixed to the output shaft end of the rotating assembly 3; in the above scheme, if Figure 4 As shown, the sampling cone rod 5 is driven to rotate by the rotating assembly 3 to complete the soil drilling and sampling operations, wherein the rotating assembly 3 can be selected in many ways, such as an electric rotating device or a hydraulic rotating device.

[0041] This embodiment also includes Figure 5-Figure 9The technical scheme shown is as follows: first, the upper and lower ends of the elastic telescopic rod 4 are respectively hingedly rotated with the bottom shell of the rotating component 3 and the upper outer wall of the sampling tube 2, wherein the elastic telescopic rod 4 is evenly distributed at equal angles; a spring is sleeved on the outer wall of the middle section of the elastic telescopic rod 4, and an electromagnetic combiner 401 is also arranged inside the elastic telescopic rod 4, and the electromagnetic combiner 401 controls the extension and retraction of the elastic telescopic rod 4; wherein the electromagnetic combiner 401 includes an electromagnet and a permanent magnet; wherein the installation setting of the elastic telescopic rod 4 realizes the preliminary positioning of the sampling cone rod 5 and the rotating component 3, so that the rotating component 3 can stably drive the sampling cone rod 5 to rotate and destroy the base soil, and at the same time, the elastic telescopic rod 4 can perform vertical buffering and shock-absorbing protection on the sampling cone rod 5 in sampling, so that the sampling cone rod 5 can be lifted and lowered, and at the same time, the electromagnetic combiner 401 drives the elastic telescopic rod 4 to freely extend and retract, so that the sampling cone rod 5 can perform buffering and lifting protection during operation, and can also control the lifting and lowering of the sampling cone rod 5 to complete subsequent sampling operations.

[0042] The sampling cone rod 5 is coaxially arranged with the sampling tube 2, and the left and right sides of the inside of the sampling tube 2 are provided with inclined plates 6, and a connecting rod 7 is fixed between the inclined plates 6 on both sides, and the upper end of the connecting rod 7 is connected to the electromagnetic controller 8 on the outer wall of the upper end of the sampling tube 2; the lower end of the sampling cone rod 5 is a spiral cone, and the outer wall of the upper section is a smooth round rod; the maximum outer diameter of the spiral cone at the lower end of the sampling cone rod 5 is equal to the outer diameter of the sampling tube 2, and the sampling cone rod 5 and the sampling tube 2 form a relative lifting structure; the inclined plates 6 are arranged on the left and right sides of the inside of the sampling tube 2 There are two groups, and the inclined plates 6 in each group are parallel and inclined to each other, and the inclined plates 6 between the two groups are staggered in the horizontal plane; the arc-shaped outer wall of the inclined plate 6 is in contact with the inner wall of the sampling tube 2, and the middle part of the inclined plate 6 is in a through-type fitting and sliding connection with the outer wall of the smooth round rod of the upper section of the sampling cone rod 5, and the top of the sampling tube 2 is provided with a discharge port 201 for sampling and discharging; the inclined plate 6 shortens the upper cantilever force arm of the sampling cone rod 5; the electromagnetic controller 8 controls the connection rods 7 on the left and right sides of the sampling tube 2 to rise and fall synchronously in different directions.

[0043] By using the above technical solution, firstly, the arrangement and distribution of the inclined plates 6 can stabilize the installation of the sampling cone rod 5, so that it can be lifted and lowered stably without left and right front and back azimuth deviation during lifting and lowering. At the same time, the lifting and lowering operation of the sampling cone rod 5 when drilling the soil can push the soil toward the lower port of the sampling tube 2 under the action of the lifting power, so that the soil material is gathered at the lower port position of the sampling tube 2, which is convenient for subsequent sampling; wherein the electromagnetic controller 8 controls the inclined plate 6 to be lifted and lowered continuously through the connecting rod 7, and the inclined plates 6 on the left and right sides are lifted and lowered synchronously in different directions. For example, when the inclined plate 6 at the bottom on the left receives the soil material gathered at the lower port of the sampling tube 2, when it rises, the soil sample material is lifted and lowered under the influence of gravity and sampling. Under the action of the external force of the rotation and lifting of the sample cone rod 5, it is shaken off and the fallen soil sample material falls onto the lowest inclined plate 6 on the right side. The lowest inclined plate 6 on the right side continues to lift and lower so that the sample material on it falls onto the second to last inclined plate 6 on the left side. Similarly, during the synchronous lifting and lowering movement of the inclined plates 6 on the left and right sides in different directions, the soil material, including the sample in a semi-fluid mixed state, is transported from bottom to top to the uppermost inclined plate 6. The sample material accumulated on the uppermost inclined plate 6 falls to the position of the discharge port 201 on the sampling tube 2 due to the influence of external force factors such as its tilt state and movement, thereby realizing the discharge of the soil sample material, which is convenient for the monitoring personnel to take samples and use in subsequent soil testing.

[0044] During the lifting and lowering movement of the above-mentioned inclined plate 6, the kinetic energy of its lifting and lowering can guide the accumulated soil samples downward. At the same time, the rotation and lifting kinetic energy of the sampling cone rod 5 can also accelerate this process, thereby improving the material extraction and sampling efficiency of the soil sample. The installation of the inclined plate 6 can limit the sampling cone rod 5, thereby preventing the sampling cone rod 5 from being twisted and damaged due to the large span of the force arm during rotation, thereby achieving the protection effect of the sampling cone rod 5.

[0045] Furthermore, in the present technical solution, the uppermost inclined plate 6 inside the sampling tube 2 is tilted toward the discharge port 201, wherein an elastic rubber film is provided at the bottom of the straight edge of the inclined plate 6 inside the sampling tube 2; the electromagnetic controller 8 is a magnetic lifting component controlled by an electromagnet, and uses magnetic repulsion and suction to control the lifting and lowering movement of the connecting rod 7 and the inclined plate 6; the lifting and lowering of the connecting rod 7 and the inclined plate 6 are controlled by the repulsion and suction of the electromagnet, so as to control the stable lifting and lowering of the connecting rod 7, and at the same time, the elastic rubber film of the inclined plate 6 is set, and through the guidance of the elastic rubber film, the soil samples accumulated on the upper inclined plate 6 are stably guided to the lower inclined plate 6 during the lifting and lowering process of the inclined plate 6, and the soil samples are stably transported from bottom to top through the staggered setting of the inclined plates 6.

[0047] When drilling and sampling the soil, the hydraulic pushing component 10 drives the positioning member 1 and the sampling tube 2 thereon to rise and fall, thereby achieving the effect of adjusting the sampling depth. At the same time, a lateral rod 12 is also provided on the positioning bracket 9. The setting of the lateral rod 12 enables it to be installed on a mobile frame to complete the soil sampling operation. At the same time, a handle can also be provided on the lateral rod 12, so that the sampler can be used by hand for easy transportation and use.
