Description

Technical Field

[0001] This invention relates to the field of deep soil and water sampling devices, and in particular to a deep soil and water sampling device for wetlands and a sampling method for use with engineering machinery. Background Technology

[0002] Wetlands are important and rich ecosystems on Earth, with huge resource potential and environmental regulation functions, and are of great value for development and utilization. Soil sampling is often required in wetland research, which necessitates the use of sampling devices.

[0003] In practice, a common sampling device is a sampling cylinder with an open bottom. It is equipped with a motor that drives the sampling cylinder to rotate, and together with construction machinery (commonly excavators, tracked vehicles, trucks, etc.), the sampling cylinder is inserted into the ground, forcing the soil into the cylinder. The cylinder is then pulled out to extract the soil. While convenient, this method is only suitable for harder soils. When extracting more fluid mud, the downward-facing sampling cylinder causes the mud to flow out upon extraction, making sampling impossible. Summary of the Invention

[0004] In view of the problem in the above or existing technology that when sampling through a sampling tube with an opening at the lower end, the mud with high fluidity is removed, and the mud flows out when the sampling tube is pulled out of the ground due to the downward direction of the sampling tube, making it impossible to sample, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A drilling component includes a mounting ring fixed to a boom, a motor fixedly connected to the mounting ring via a bracket, a rotating drum with an open lower end fixedly connected to the output shaft of the motor, multiple inner grooves on the side wall of the rotating drum, and a water sampling tube with an open upper end disposed within each of the inner grooves, the water sampling tube moving outwards to sample water; a transmission component includes a guide assembly mounted on the mounting ring, a guide ring fixedly connected to the side wall of the rotating drum, a push-out assembly providing power to the water sampling tube inside the rotating drum, a threaded assembly providing power to the push-out assembly on the mounting ring, a lifting ring on the upper side of the rotating drum cooperating with the motor output shaft, and a rotating assembly and a one-way assembly providing power to the threaded assembly; a lifting component includes a telescopic assembly mounted on the lifting ring, and a centrifugal assembly providing power to lift the lifting ring on the motor output shaft.

[0006] In a preferred embodiment of the wetland deep soil and water sampling device of the present invention, the guiding component includes an annular groove disposed on the mounting ring, the guiding ring cooperates with the annular groove, and the outer side wall and the lower side wall of the guiding ring are provided with balls that cooperate with the annular groove.

[0007] In a preferred embodiment of the wetland deep soil and water sampling device of the present invention, the ejection component includes three L-shaped grooves disposed on a guide ring, the L-shaped grooves extending into the rotating cylinder, a sliding plate slidably connected in the L-shaped grooves, a plurality of push plates fixedly connected on the sliding plate, the plurality of inner grooves being divided into three rows, the L-shaped grooves communicating with the inner grooves through a connecting groove, the plurality of push plates extending into the inner grooves and fixedly connected to the water sampling cylinder, the lower end of the rotating cylinder being conical, and an expansion ring fixedly connected to the lower end of the rotating cylinder.

[0008] In a preferred embodiment of the wetland deep soil and water sampling device of the present invention, the threaded assembly includes three damping shafts that pass through and are rotatably connected to the mounting ring. A reciprocating screw is fixedly connected to the lower end of each of the three damping shafts. An annular opening is provided on the guide ring, and a transmission ring is provided without contact within the annular opening. The transmission ring is slidably connected to the inner wall of the annular groove and is threadedly connected to the reciprocating screw. An L-shaped plate that cooperates with the transmission ring passes through and is slidably connected to the L-shaped groove. The L-shaped plate is elastically connected to the inner wall of the L-shaped groove via a first spring. Inclined grooves are provided on both the front and rear side walls of the L-shaped plate. A U-shaped plate is fixedly connected to the sliding plate, and a lever that cooperates with the inclined groove is fixedly connected to the U-shaped plate.

[0009] As a preferred embodiment of the wetland deep soil and water sampling device of the present invention, the projected length of the inclined trough is greater than the length of the push plate, and the projected width of the inclined trough is less than the distance between the U-shaped plate and the bottom of the inner side of the L-shaped trough.

[0010] In a preferred embodiment of the wetland deep soil and water sampling device of the present invention, the rotating component includes a fixed ring fixedly connected to the lifting ring, the fixed ring having multiple locking blocks, a support disk fixedly connected to the damping rotating shaft, and an extension block cooperating with the locking blocks fixedly connected to the support disk.

[0011] As a preferred embodiment of the wetland deep soil and water sampling device of the present invention, the unidirectional component includes a receiving groove on a support plate, the extension block is elastically connected to the inner wall of the receiving groove by a second spring, and the extension block and the locking block are provided with mutually cooperating tangential edges.

[0012] In a preferred embodiment of the wetland deep soil and water sampling device of the present invention, the telescopic component includes a cylinder fixedly connected to a rotating cylinder, a connecting column slidably connected inside the cylinder, the upper end of the connecting column being fixedly connected to a lifting ring, and the connecting column being elastically connected to the inner wall of the cylinder via a third spring.

[0013] In a preferred embodiment of the wetland deep soil and water sampling device of the present invention, the centrifuge assembly includes a rigid rope fixedly connected to the motor output shaft, a counterweight ball fixedly connected to the rigid rope, and two strip-shaped openings on the lifting ring that cooperate with the rigid rope. The width of the strip-shaped openings is smaller than the diameter of the counterweight ball, and the inner wall of the lifting ring does not contact the motor output shaft.

[0014] A sampling method for use with engineering machinery includes: fixing an installation ring to the boom of the engineering machinery; turning on the motor to drive the rotating drum to rotate, and the boom movement driving the rotating drum downwards to drive the drum into the ground; determining whether the motor needs to be reversed based on the soil's fluidity; if the soil fluidity is low, the rotating drum can be directly pulled out; if the soil fluidity is high, the motor is reversed; driving multiple sampling cylinders to first extend out of the inner groove and then return to their original position via transmission to sample the mud; the rotating drum moving upwards to move the multiple sampling cylinders to the ground; and removing the soil from the sampling cylinders to complete the sampling process.

[0015] The beneficial effects of the wetland deep soil and water sampling device and its sampling method in conjunction with engineering machinery of the present invention are as follows:

[0016] 1. By setting up drilling and transmission components, multiple sampling tubes are installed on the side wall of the rotating drum. The rotating drum opening faces downward to extract harder soil, while the sampling tube opening faces upward to extract more fluid mud, thus making the application range wider.

[0017] 2. By setting up a rotating component and a one-way component, when the motor rotates forward, the rotating drum can be adjusted to rotate, making it easier for the drum to penetrate into the ground. When the motor rotates in reverse, the sampling drum can be driven to extend and then reset through transmission. This allows the extraction of hard soil and mud to share the power of a single motor, making it convenient to use and easy to maintain.

[0018] 3. By setting up a lifting component, when the motor output shaft rotates clockwise, the lifting ring can also be driven upward by centrifugal force. This drives the locking block and the extension block to separate through transmission, avoiding continuous collision between the locking block and the extension block and extending their service life.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example 1, referring to Figures 1 to 7This is the first embodiment of the present invention, which provides a wetland deep soil and water sampling device capable of sampling soil or groundwater-soil mixtures. It includes a drilling component, comprising a mounting ring 10 fixed to a boom, a motor 12 fixedly connected to the mounting ring 10 via a bracket 11, and a rotating drum 13 with an open lower end fixedly connected to the output shaft of the motor 12. The rotating drum 13 has multiple inner grooves 14 on its side wall, and a water sampling tube 15 with an open upper end is disposed within each inner groove 14. The water sampling tube 15 moves outward to sample water. A transmission component is also included, comprising a mounting ring 10 fixed to the boom. The guide assembly 20 on the ring 10, the guide ring 21 fixedly connected to the side wall of the rotating drum 13, the ejection assembly 22 that provides power to the water intake tube 15 inside the rotating drum 13, the threaded assembly 23 that provides power to the ejection assembly 22 on the mounting ring 10, the lifting ring 24 that cooperates with the output shaft of the motor 12 on the upper side of the rotating drum 13, the lifting ring 24 that provides power to the threaded assembly 23 and the one-way assembly 26; the lifting component includes the telescopic assembly 30 set on the lifting ring 24, and the centrifugal assembly 31 that provides power to lift the lifting ring 24 on the output shaft of the motor 12.

[0030] Specifically, the boom here is connected to construction machinery, commonly construction vehicles, excavators, etc. There are no specific restrictions, as long as it can provide downward force to the boom and can move on relatively wet ground. The connection between the construction machinery and the boom is existing technology and will not be elaborated here. Of course, the boom and the mounting ring 10 can also be fixed by mechanical gripping. There is no only one way to fix it. As long as the mounting ring 10 and the boom can form a stable effect, the motor 12 here is a servo motor 12, and its forward and reverse rotation speeds are different. This is existing technology and will not be elaborated here. The model of the motor 12 is adapted according to the depth of the drum 13 driven into the ground and is not limited here.

[0031] Furthermore, the guide assembly 20 includes an annular groove 201 disposed on the mounting ring 10, the guide ring 21 cooperates with the annular groove 201, and the outer side wall and the lower side wall of the guide ring 21 are provided with ball bearings 202 that cooperate with the annular groove 201; the ejection assembly 22 includes three L-shaped grooves 221 disposed on the guide ring 21, the L-shaped grooves 221 extend into the rotating cylinder 13, a sliding plate 222 is slidably connected in the L-shaped grooves 221, a plurality of push plates 223 are fixedly connected on the sliding plate 222, a plurality of inner grooves 14 are divided into three rows, the L-shaped grooves 221 communicate with the inner grooves 14 through a connecting groove, the plurality of push plates 223 extend into the inner grooves 14 and are fixedly connected to the water intake cylinder 15, the lower end of the rotating cylinder 13 is conical, and an expansion ring 224 is fixedly connected to the lower end of the rotating cylinder 13.

[0032] The ball bearing 202 reduces the frictional resistance between the guide ring 21 and the inner wall of the annular groove 201, extending the service life of the guide ring 21. There can be multiple L-shaped grooves 221, but no fewer than three. There are also no fewer than three water sampling tubes 15 in a row, which enables sampling at multiple locations and different depths, ensuring the breadth and accuracy of sampling. Elastic rubber is provided in the inner groove 14 to seal the upper end of the water sampling tube 15 and prevent the sample from leaking out after sampling.

[0033] Preferably, the threaded assembly 23 includes three damping shafts 231 that pass through and are rotatably connected to the mounting ring 10. Each of the three damping shafts 231 has a reciprocating screw 232 fixedly connected to its lower end. The guide ring 21 has an annular opening 233, within which a transmission ring 234 is disposed without contact. The transmission ring 234 is slidably connected to the inner wall of the annular groove 201 and threadedly connected to the reciprocating screw 232. An L-shaped groove 221 passes through and is slidably connected to the transmission ring 234. The L-shaped plate 235 is elastically connected to the inner wall of the L-shaped groove 221 via a first spring 236. The front and rear side walls of the L-shaped plate 235 are provided with inclined grooves 237. A U-shaped plate 238 is fixedly connected to the slide plate 222. A lever 239 that cooperates with the inclined groove 237 is fixedly connected to the U-shaped plate 238. The projected length of the inclined groove 237 is greater than the length of the push plate 223, and the projected width of the inclined groove 237 is less than the distance from the U-shaped plate 238 to the bottom of the horizontal side of the L-shaped groove 221.

[0034] It should be noted that there must be at least three damping shafts 231 here, which drive the transmission ring 234 to move from three positions, making the movement of the transmission ring 234 more stable. The L-shaped plate 235 is misaligned with the reciprocating screw 232, so that there will be no collision between the reciprocating screw 232 and the L-shaped plate 235. The L-shaped plate 235 is provided with a guide block, and a guide groove that cooperates with the guide block is provided on the inner wall of the L-shaped groove 221, so as to guide the L-shaped plate 235 when it moves up and down.

[0035] Furthermore, the rotating component 25 includes a fixed ring 251 fixedly connected to the lifting ring 24, the fixed ring 251 having multiple locking blocks 252, a support plate 253 fixedly connected to the damping shaft 231, and an extension block 254 cooperating with the locking blocks 252 fixedly connected to the support plate 253; the one-way component 26 includes a receiving groove 261 provided on the support plate 253, the extension block 254 being elastically connected to the inner wall of the receiving groove 261 by a second spring 262, and the extension block 254 and the locking blocks 252 having mutually cooperating cut edges 263.

[0036] It should be noted that the setting of the cutting edge 263 here means that when the two cutting edges 263 abut against each other, the extension block 254 will enter the receiving groove 261 under the action of extrusion force. When the non-cutting edge 263 of the extension block 254 abuts against the non-cutting edge 263 of the locking block 252, the lifting ring 24 drives the fixing ring 251 to rotate, which in turn drives the support plate 253 to rotate.

[0037] When sampling harder soil, turn on motor 12. The output shaft of motor 12 rotates clockwise (viewed from above, the same applies below), driving the rotating drum 13 to rotate. As the rotating drum 13 rotates, the guide ring 21 moves within the annular groove 201, guiding the rotating drum 13. After the rotating drum 13's rotation speed stabilizes, the cone at the bottom of the rotating drum 13 contacts the ground. The boom provides downward pressure, driving the rotating drum 13 into the ground. At this point, under the pressure, soil will enter the rotating drum 13. Then, motor 12 stops. To stop the rotation, the boom lifts the mounting ring 10, which drives the guide ring 21 upward, and then drives the rotating drum 13 upward. Once the rotating drum 13 reaches the ground, the soil inside the rotating drum 13 can be removed. During this process, when the output shaft of the motor 12 rotates and drives the lifting ring 24 to rotate (in this embodiment, the output shaft of the motor 12 is fixed to the lifting ring 24), the cut edge 263 of the locking block 252 on the fixed ring 251 cooperates with the cut edge 263 on the extension block 254, which will not drive the support plate 253 to rotate, and will not cause the damping shaft 231 to rotate.

[0038] When underground mud or water sampling is required, the rotating drum 13 is first moved to the required depth using the above method. During this process, the expanding ring 224 ensures that the hole drilled by the rotating drum 13 is larger than the diameter of the drum 13, preventing the surrounding soil from causing excessive pressure on the water sampling cylinder 15 and deforming it. When the rotating drum 13 reaches the required position, the output shaft of the motor 12 reverses, causing the lifting ring 24 to rotate. This causes the non-cut edge 263 of the locking block 252 on the fixed ring 251 to abut against the non-cut edge 263 of the extension block 254 on the support plate 253, which in turn causes the support plate 253 to rotate. This, in turn, causes the damping shaft 231 to rotate, causing the reciprocating screw 232 to rotate. This causes the transmission ring 234 to move up and down reciprocally. When the transmission ring 234 moves downward, it will press the L-shaped plate 235, causing the first... When the spring 236 is compressed, the lever 239 engages with the inclined groove 237 as the L-shaped plate 235 moves downward. The inclined groove 237 is higher on the left and lower on the right. When the L-shaped plate 235 moves downward, the lever 239 moves towards the L-shaped plate 235, the U-shaped plate 238 moves towards the L-shaped plate 235, and the slide plate 222 moves towards the L-shaped plate 235. This causes the push plate 223 to move outward, which in turn moves the sampling cylinder outward to sample water or mud. It is worth noting that when the sampling cylinder moves outward, the inner end of the sampling cylinder is always within the inner groove 14, which prevents mud from entering the inner groove 14 and affecting the sampling cylinder's reset. At the same time, an inclined edge is also provided on the sampling cylinder. At this time, the rotating cylinder 13 still rotates at a slight angle. The inclined edge cooperates with the rotation, allowing the mud to enter the sampling cylinder better.

[0039] The diameter of the fixed ring 251 is much larger than the diameter of the support plate 253, and the number of locking blocks 252 on the fixed ring 251 is much larger than the number of extension blocks 254 on the support plate 253. As a result, when the reciprocating screw 232 drives the transmission ring 234 to reciprocate, the angle of rotation of the lifting ring 24 is small, which will not cause excessive impact between the sampling tube and the underground soil. At the same time, the distance between the outer wall of the expanding ring 224 and the outer wall of the rotating cylinder 13 is smaller than the width of the sampling tube.

[0040] In summary, by setting up drilling and transmission components, the rotating drum 13 can be driven to sample harder soil by the forward and reverse rotation of the motor 12. Furthermore, by using the ejection component 22, the sampling tube can be automatically ejected after the rotating drum 13 enters the ground to sample mud or water. This integrates sampling of harder soil, mud, and water, resulting in a wider sampling range and more application scenarios.

[0041] Example 2, refer to Figures 1 to 7This is the second embodiment of the present invention. Unlike the previous embodiment, based on embodiment 1, this embodiment provides a lifting component for a deep wetland soil and water sampling device, which solves the problem of how to avoid the large wear caused by the constant collision between the extension block 254 and the locking block 252. It includes a telescopic component 30, which includes a cylinder 301 fixedly connected to the rotating cylinder 13. A connecting column 302 is slidably connected inside the cylinder 301. The upper end of the connecting column 302 is fixedly connected to the lifting ring 24. The connecting column 302 is elastically connected to the inner wall of the cylinder 301 through a third spring 303. The centrifugal component 31 includes a rigid rope 311 fixedly connected to the output shaft of the motor 12. A counterweight ball 312 is fixedly connected to the rigid rope 311. The lifting ring 24 is provided with two strip-shaped openings 313 that cooperate with the rigid rope 311. The width of the strip-shaped openings 313 is smaller than the diameter of the counterweight ball 312. The inner wall of the lifting ring 24 does not contact the output shaft of the motor 12.

[0042] Specifically, the width of the strip opening 313 is smaller than the diameter of the counterweight ball 312, so that when the counterweight ball 312 moves, it will not move to the upper side of the lifting ring 24. At the same time, the diameter of the lifting ring 24 is sufficient to prevent the counterweight ball 312 from moving to the outside of the lifting ring 24. In this embodiment, the inner wall of the lifting ring 24 does not contact the output shaft of the motor 12, thereby ensuring that the lifting ring 24 can perform lifting and lowering movements.

[0043] During use, it is worth noting that when the output shaft of motor 12 rotates clockwise, the speed is very fast, while the speed is slower when rotating counterclockwise. This rapid rotation of the output shaft causes the rigid rope 311 to rotate rapidly around it. Under the action of centrifugal force, the rigid rope 311 gradually moves from an inclined position to a horizontal position and maintains a stable horizontal state. During this process, the lifting ring 24 and connecting column 302 move upwards, and the third spring 303 extends, causing the fixing ring 251 to move upwards. This separates the locking block 252 from the extension block 254, thus facilitating rotation. The locking block 252 and the extension block 254 do not contact each other, thus avoiding continuous collision between them, reducing wear, and extending their service life. It is worth noting that the motor 12 rotates a full circle, and there are a large number of locking blocks 252, which ensures that the locking blocks 252 continue to cooperate with the extension block 254 when the lifting ring 24 is reset. The cylinder 301 is fixed to the rotating cylinder 13, so that the counterweight ball 312 and the lifting ring 24 rotate together, while the two remain relatively stationary, thus avoiding wear between the counterweight ball 312 and the lifting ring 24.

[0044] In summary, by setting up a lifting component, when the output shaft of motor 12 rotates, under the action of centrifugal force, it can also drive the rigid rope 311 to slowly change from an inclined state to a horizontal state, so that the lifting ring 24 moves upward, causing the locking block 252 and the extension block 254 on the fixed ring 251 to separate, avoiding the locking block 252 and the extension block 254 from colliding continuously, and extending the service life of the locking block 252 and the extension block 254.

[0045] Example 3 is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a sampling method in conjunction with engineering machinery, which includes:

[0046] S1: Secure the mounting ring 10 to the boom on the engineering machinery (such as tracked engineering vehicles);

[0047] S2: Turn on motor 12 to drive drum 13 to rotate, and the boom movement will drive drum 13 to move down and drive drum 13 into the ground;

[0048] S3: Determine whether motor 12 needs to be reversed based on the soil's fluidity;

[0049] S4: If the soil has low fluidity, simply remove the rotating drum 13;

[0050] S5: Motor 12 reverses when the soil has high fluidity;

[0051] S6: Multiple sampling cylinders are driven by transmission to first extend out of the inner groove 14 and then return to their original positions to sample the mud.

[0052] S7: Rotating drum 13 moves upward, causing multiple sampling cylinders to move to the ground;

[0053] S8: Remove the soil from the sampling tube to complete the sampling process.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
