Description

Technical Field

[0001] The invention relates to an original soil taking device for an overwater covering layer, belonging to the technical field of overwater covering layer soil taking. Background Art

[0002] The overwater cover refers to various material layers covering the water body, with thickness ranging from a few centimeters to several meters or even thicker, and the thickness depends on many factors such as sedimentation rate, water flow conditions, biological activities, etc. The material layer is composed of many different components and characteristics, including inorganic matter (such as mud, gravel) and organic matter (such as plant residues and animal remains). The combination and proportion of the substances determine the physical, chemical and biological properties of the cover. The overwater cover can affect environmental factors such as the dissolved oxygen content, water temperature, and light conditions of the water body, thereby affecting the survival and reproduction of aquatic organisms. At the same time, pollutants in the cover may also have a negative impact on water quality. In order to more accurately obtain the physical, chemical and biological properties of the overwater cover, it is necessary to take soil samples of the overwater cover.

[0003] The overwater covering layer is mostly formed by the deposition of impurities in the water, and its main characteristic is that it has rich water content. When taking soil from the overwater covering layer, it is necessary to ensure the integrity of the soil as much as possible because of the need to test its composition and water content.

[0004] Most of the existing soil sampling devices use a drilling coring machine to extract soil samples. If it is directly used to extract soil from the overwater layer, it is easy to damage the original soil. Especially when the water content is high, the pattern is easy to slip, and other tools are needed to achieve soil sampling, which makes it difficult to ensure the integrity of the original soil sample. In addition, the original soil sampling needs to be sealed and preserved in time, but the traditional soil sampling device does not have such a function. Therefore, it is not feasible to use the traditional soil sampling device directly for the original soil sampling of the overwater layer. Summary of the invention

[0041] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] The carrier assembly 100 is provided with a soil taking assembly 500 that can be raised and lowered, and the soil taking assembly 500 is connected to the carrier assembly 100 via a disassembly assembly 400;

[0044] The support assembly 200 is installed on one side of the bottom of the carrier assembly 100;

[0045] The reset component 300 is fixedly mounted on the bottom of the bracket component 200, and the reset component 300 is correspondingly arranged on one side of the carrier component 100;

[0046] The collecting assembly 600 is movably connected below the bracket assembly 200. When the collecting assembly 600 rotates, the collecting assembly 600 is fitted and sleeved with the bottom of the soil taking assembly 500. When the collecting assembly 600 and the soil taking assembly 500 are spliced, the soil taking assembly 500 corresponds to the resetting assembly 300.

[0047] The carrier assembly 100 includes a vertical plate 101, a driving motor 102 is fixedly installed on one side of the top of the vertical plate 101, and both ends of the other side of the vertical plate 101 are fixedly connected to the support 103, the inside of the support 103 is rotatably connected with the long screw 208104, the output end of the driving motor 102 and the long screw 208104 are fixedly connected to the pulley 105, and the pulleys 105 are connected by a belt 106 for transmission; two symmetrically distributed limit plates 109 are fixedly installed on the side wall of the vertical plate 101, and the cross-sections of the two limit plates 109 are both L-shaped structures and are symmetrically distributed on both sides of the support 103, and a drilling rig 108 is provided between the two limit plates 109, and the bottom of the drilling rig 108 is fixedly connected to the base 107, and the base 107 is located inside the limit plate 109 and is slidably connected to the surface of the vertical plate 101.

[0048] In the present technical solution, the carrier assembly 100 serves as a carrier of the soil-taking device, which can drive the soil-taking device to rise and fall, not only realizing rapid lifting and lowering of the drilling hole, but also facilitating the preservation of soil samples in cooperation with the subsequent collecting assembly 600. During operation, after the vertical plate 101 is stably installed, the driving motor 102 is started, and the cooperation of the belt 106 and the pulley 105 drives the long screw 208104 to rotate on the support 103, so that the long screw 208104 drives the drilling rig 108 on the base 107 to move, and the base 107 is limited by the limiting plate 109 to realize the stable lifting and lowering of the drilling rig 108, thereby driving the drilling rig 108, the disassembly and assembly assembly 400 and the soil-taking assembly 500 to move downward to perform soil-taking operations on the water covering layer.

[0049] The bracket assembly 200 includes a transverse plate 201, which is fixedly connected to one side of the bottom of the vertical plate 101. Both sides of the top of the transverse plate 201 are fixedly connected to the vertical plate 101 through inclined reinforcing rods 202. The middle part of the reinforcing rod 202 is connected to the collecting assembly 600 through a swinging mechanism. An air pump 206 is also fixedly installed on the surface of the transverse plate 201, and the air pump 206 is connected to the bottom of the collecting assembly 600 through a hose 207.

[0050] In the present technical solution, the horizontal plate 201 is stably installed on the side wall of the vertical plate 101 by means of the reinforcing rod 202. The reinforcing rod 202 is also used for connecting the swing mechanism. The collecting assembly 600 is connected through the swing mechanism to facilitate the movement of the collecting assembly 600. After the collecting assembly 600 is moved into place and matched with the soil collecting assembly 500, the air pump 206 is started to circulate air through the hose 207, so as to facilitate the rapid storage of soil samples.

[0051] The swing mechanism includes a swing rod 203, the middle part of the swing rod 203 is rotatably connected to the reinforcing rod 202, the top of the swing rod 203 is fixedly connected to the cross rod 204, the middle part of the cross rod 204 is rotatably connected to the telescopic end of the first electric push rod 205, and the first electric push rod 205 is rotatably connected to the side wall of the vertical plate 101, the bottom of the swing rod 203 is threadedly connected to the screw 208, and the screw 208 is rotatably connected to the inside of the collection component 600.

[0052] In the present technical solution, when the first electric push rod 205 is extended, it pushes the cross bar 204 and the rocker arm 203 to rotate. When the rocker arm 203 rotates around the middle of the reinforcing rod 202, it drives the collecting assembly 600 to approach the soil-excavating assembly 500. Since the rocker arm 203 is movably connected to the collecting assembly 600 through the screw rod 208, and the screw rod 208 is movably inserted above the collecting assembly 600, the center of gravity of the collecting assembly 600 is located below the screw rod 208. At this time, the rotation of the rocker arm 203 makes the collecting assembly 600 always in a vertical state and move it to the bottom of the soil-excavating assembly 500, so that the collecting assembly 600 and the soil-excavating assembly 500 can cooperate and dock with each other.

[0053] The reset assembly 300 includes a second electric push rod 301, which is fixedly installed at the bottom of the cross plate 201. The telescopic end of the second electric push rod 301 is fixedly connected with a plug plate 302. A plurality of arc-shaped protrusions 303 are provided on one side edge of the plug plate 302. The plug plate 302 is slidably connected to the bottom surface of the cross plate 201. When the plug plate 302 moves, the plug plate 302 and the protrusions 303 both extend into the interior of the soil taking assembly 500.

[0054] In the present technical solution, after the collecting component 600 and the soil taking component 500 cooperate and complete docking, the long hole 512 of the soil taking component 500 corresponds to the reset component 300, and when the second electric push rod 301 is extended to push the plug plate 302 to move, the plug plate 302 drives the protrusion 303 to extend into the long hole 512, and when it contacts the cutting rope 511, the cutting rope 511 is limited by the protrusion 303. When the second electric push rod 301 is shortened, the cutting rope 511 is reset by pulling the protrusion 303, and after the cutting rope 511 moves to the outside of the rotating drum 501, the cutting rope 511 is limited again by the baffle 507.

[0055] The disassembly and assembly component 400 includes a fixed plate 401, which is fixedly connected to the output end of the drilling rig 108. The edge of the fixed plate 401 is fixedly connected to the turntable 403 through a vertical rod 402. The turntable 403 and the fixed plate 401 are respectively fixedly connected to the two ends of the third electric push rod 405. The telescopic end of the third electric push rod 405 passes through the turntable 403 and is fixedly connected to the end head 406. The end head 406 contacts the top surface of the connecting head 502. The bottom edge of the turntable 403 is movably connected to the clamp 408 through a fixing piece 404, and the edge of the end head 406 is connected to the clamp 408 through a connecting rod 407.

[0056] In the present technical solution, the third electric push rod 405 is extended to drive the end head 406 to move. At this time, the end head 406 pulls the connecting rod 407 to rotate, so that the connecting rod 407 pulls the clamping jaw 408 to rotate on the fixing member 404, so that the clamping jaw 408 is clamped on the surface of the connecting head 502, and the clamping jaw 408 is clamped into the inside of the card slot 503, thereby completing the stable fixation of the soil taking assembly 500. After the operation is completed, the drilling rig 108 drives the fixed plate 401 to rotate when working, so that the fixed plate 401 drives the vertical rod 402 and the turntable 403 to rotate at the same time, and the turntable 403 drives the soil taking assembly 500 on the clamping jaw 408 to rotate to perform the drilling and coring operation.

[0057] The soil taking assembly 500 includes a rotating drum 501, a connecting head 502 is fixedly connected to the top of the rotating drum 501, a slot 503 matching with a claw is provided on the top edge of the connecting head 502, a cutting edge 504 is provided at the bottom of the rotating drum 501, a plurality of drill bits 505 are provided on the rotating drum 501 above the cutting edge 504, and a long hole 512 with a semicircular structure is opened on the surface of the drill drum above the drill bit 505, an electromagnetic telescopic rod 506 is fixedly installed on the outer wall of the rotating drum 501, the electromagnetic telescopic rod 506 consists of an electromagnetic coil and an armature, the electromagnetic coil is installed to the side wall of the rotating drum 501, the armature is movably connected to the inside of the electromagnetic coil, and the armature is fixedly connected to a baffle 507 with an arc structure, the baffle 507 is fitted and connected to the surface of the rotating drum 501, and the baffle 507 is distributed correspondingly to the long hole 512 on the rotating drum 501.

[0058] In the present technical solution, when the disassembly assembly 400 drives the soil taking assembly 500 to rotate, the soil layer is cut by the cutting edge 504 and the drill bit 505, and the shear force generated during drilling diffuses outward, while the soil sample is stored inside the rotating drum 501. The soil around the soil sample is destroyed by the cutting edge 504 and the drill bit 505 without affecting the soil sample inside the rotating drum 501. At the same time, the exposed drill bit 505 is used to ensure that the surface structure of the rotating drum 501 is not affected by the soil. After the drilling is completed, the electromagnetic telescopic rod 506 is energized. At this time, the magnetic field generated by the electromagnetic coil drives the armature to retract, and then drives the baffle 507 to move upward. At this time, the baffle 507 is separated from the cutting rope 511, so that the cutting rope 511, which was originally an arc-shaped structure, is pulled and straightened, and the generated tension cuts the bottom of the soil sample.

[0059] The bottom of the rotating drum 501 is fixedly connected to the first set of plates 508 and the second set of plates 513 respectively. The first set of plates 508 and the second set of plates 513 are both arc-shaped structures and are connected to each other. The first set of plates 508 has an arc-shaped rod 509 movably sleeved inside. One end of the arc-shaped rod 509 located on the outside of the first set of plates 508 is fixedly connected to a connecting block 510. The connecting block 510 is located on one side of the baffle 507. The connecting block 510 is connected to the rejuvenation surface through a cutting rope 511. The connection between the cutting rope 511 and the rotating drum 501 is located on the other side of the baffle 507, and the cutting rope 511 is fitted and connected to the surface of the baffle 507.

[0060] In the present technical solution, the first set of plates 508 is used to limit the arc rod 509, so that the arc rod 509 can move inside the first set of plates 508. The arc rod 509, the first set of plates 508 and the second set of plates 513 are all arc structures, which can make the arc rod 509 move around the surface of the rotating drum 501. The arc rod 509 can drive the connecting block 510 to move, and the other end of the arc rod 509 moves inside the first set of plates 508 through the spring 517. When the baffle 507 blocks the cutting rope 511, the pull rope is in a stretched state. When the baffle 507 is separated from the cutting rope 511, the spring 517 pulls the connecting block 510 to move, so that the connecting block 510 pulls the cutting rope 511 from the arc state to the vertical state, and the cutting rope 511 passes through the long hole 512 and is embedded in the rotating drum 501. When the rotating drum 501 drives the cutting rope 511 to rotate, the bottom of the cylindrical soil sample is cut. During the shear force generated during cutting, the spring 517 also plays a buffering function, so that the cutting rope 511 can be gradually cut at its bottom as the rotating drum 501 rotates.

[0061] The cross-sections of the first set of plates 508 and the second set of plates 513 are both U-shaped structures. The first set of plates 508 are connected to the arc rod 509 via a spring 517. The arc rod 509 is fixedly connected to a fixing rod 515 located on one side of the spring 517. The fixing rod 515 is an arc structure and extends to the inside of the second set of plates 513. The end of the second set of plates 513 away from the fixing rod 515 is rotatably connected to a support plate 514. The other end of the support plate 514 is connected to the fixing rod 515 via a movable rod 516, and the movable rod 516 is tiltedly arranged inside the second set of plates 513.

[0062] In the present technical solution, when internal cutting is performed after the drilling is completed, the arc rod 509 is pulled by the spring 517 to move toward the inside of the first set of plates 508, and the arc rod 509 drives the fixed rod 515 to move to the inside of the second set of plates 513. The fixed rod 515 drives the support plate 514 to move inside the second set of plates 513 through the movable rod 516. At this time, the support plate 514 is driven by the movable rod 516 of the inclined structure to rotate from the inside of the second set of plates 513 to the inside of the rotating drum 501, and then cooperates with the cutting rope 511 to achieve cutting. At the same time, the bottom of the soil sample is supported by the cutting rope 511 and the support plate 514, so that after the drilling is completed, the soil sample is lifted by the cutting rope 511 and the support plate 514, and separated from the soil with the rotating drum 501.

[0063] The collecting assembly 600 includes a collecting barrel 601, a convex edge 602 is provided on the top of the collecting barrel 601, the inner diameter of the convex edge 602 is the same as the inner diameter of the bottom of the rotating barrel 501, an external thread connected to the barrel cover is provided on the edge of the convex edge 602, a piston 603 is sealed inside the collecting barrel 601, a push rod 604 is fixedly connected to the bottom of the collecting barrel 601, the collecting barrel 601 is connected to the hose 207, and both sides of the top of the collecting barrel 601 are movably connected to the screw 208.

[0064] In the present technical solution, when the long screw 208104 rotates forward, after the soil sample is taken out from the soil through the rotating drum 501, the rotating drum 501 moves to the top of the horizontal plate 201. At this time, the collecting drum 601 is moved to the bottom of the rotating drum 501 by the swing mechanism. At this time, the rotating drum 501 is driven to fit the top edge of the convex edge 602 by the reverse rotation of the long screw 208104, thereby completing the docking between the rotating drum 501 and the collecting drum 601. At the same time, the air pump 206 on the horizontal plate 201 works to send the outside air into the collecting drum 601 through the hose 207. The positive pressure formed at this time pushes the piston 603 to move upward to the convex edge 602 position. After the rotating drum 501 is docked with the collecting drum 601, the long hole 512 corresponds to the reset assembly 300, and the plug plate 302 drives the protrusion 303 to move The rotary drum 501 moves to the inside of the rotary drum 501, and the protrusion 303 moves to the cutting rope 511 located in the middle of the rotary drum 501. When the protrusion 303 retreats, the cutting rope 511 is pulled to move to the outside of the rotary drum 501 again. The baffle 507 moves down to block the long hole 512. At this time, the soil sample in the rotary drum 501 falls above the piston 603, and the air pump 206 stops working to discharge the gas. The piston 603 falls on the push rod 604 to preserve the soil sample. At this time, the rotary drum 501 continues to rise, so that the protrusion 303 is separated from the cutting rope 511, and the cutting rope 511 falls back to the surface of the baffle 507. The shortening of the second electric push rod 301 is used to drive the collecting barrel 601 to reset, and the screw 208 is unscrewed to remove the collecting barrel 601 from the swing rod 203, and then the barrel cover is tightened on the convex edge 602 to preserve the soil sample.
