Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, and more particularly to a contaminated soil treatment sampling device. Background Art

[0002] Contaminated soil remediation refers to taking various measures to reduce or eliminate pollutants in the soil in order to restore the ecological function and use value of the soil. At present, contaminated soil remediation technologies can be divided into four categories: physical remediation, chemical remediation, biological remediation and phytoremediation. In practical applications, it is necessary to make a comprehensive selection based on factors such as pollution type, pollution degree, and soil properties. Contaminated soil remediation sampling is a crucial part of the environmental remediation process. It provides a scientific basis for subsequent pollution assessment, remediation plan design and effect verification.

[0003] A soil sampling drill is a device used to collect samples from contaminated soil. It usually includes manual sampling drills, electric sampling drills and vibration sampling drills. Manual sampling drills are easy to operate and suitable for shallow soils; electric sampling drills are driven by motors and are suitable for deep soils; vibration sampling drills are combined with vibration functions and are suitable for hard soil and clay to improve penetration ability.

[0004] At present, when the vibrating sampling drill is used for actual sampling, the staff holds the two handles on the sampling drill, holds the sampling drill vertically and close to the ground, and then starts the vibration motor. At the same time, the staff presses the sampling drill downward to provide downward pressure for drilling, and performs sampling in conjunction with vibration. However, this sampling method still has certain defects: 1. The staff presses the sampling drill downward to provide downward pressure for drilling, which not only fails to ensure the stability and uniformity of the downward pressure, causing the sampling drill to tilt or shift in the soil, affecting the quality and accuracy of the sampling, but also the sampling drill will generate recoil force during vibration sampling, and long-term vibration sampling will cause staff fatigue.

[0005] 2. The sampling drill lacks guidance during the sampling process. Without guidance, the sampling drill is more likely to tilt in the soil, affecting the verticality and stability of the sampling. Especially when sampling hard soil or clay, the sampling drill is more likely to deviate from the predetermined sampling path.

[0006] 3. When sampling in shallow layers, the operator can keep the sampling drill stable through manual control. However, as the sampling drill is inserted deeper into the soil, the resistance of the soil gradually increases, and the sampling drill is more likely to shake, causing tilt or deviation, affecting the stability and quality of sampling. Summary of the invention

[0007] The present invention provides a contaminated soil treatment sampling device, which solves the technical problems in the prior art that the downward pressure provided by a worker pressing a sampling drill downward for drilling cannot ensure the stability of the downward pressure and the sampling drill lacks guidance during the sampling process.

[0008] The present invention provides a contaminated soil treatment sampling device, comprising a mounting ring, a multi-stage guide shock-taking unit and a side-piercing tripod unit respectively arranged on the upper and lower sides of the mounting ring, wherein the multi-stage guide shock-taking unit comprises a multi-stage guide component and a shock-taking component arranged on the multi-stage guide component, the side-piercing tripod unit comprises a tripod component and a soil-piercing component for fixing the tripod component, and a self-unlocking counterweight unit is arranged on the multi-stage guide shock-taking unit, wherein the self-unlocking counterweight unit comprises a counterweight component for providing downward pressure to the shock-taking component, a control component for cooperating with the tripod component to fix and unlock the counterweight component, and a pulling component for pulling the control component.

[0010] When sampling, the vibration component is placed perpendicular to the ground and the tripod component is unfolded. When unfolding, the tripod component will drive the pulling component to pull the control component, unlock the counterweight, so that the vibration component falls to the ground and the soil piercing component is driven into the soil to fix the tripod. Then, when the vibration component vibrates, the counterweight presses down the vibration component to insert the soil for sampling, and the soil piercing component penetrates deeper as the vibration component vibrates.

[0011] Furthermore, the multi-stage guide assembly also includes a guide slider 1 slidably connected in the guide slot, a mounting plate is commonly installed between several guide sliders, several circumferentially distributed fixing rods are fixedly installed on the inner side of the mounting ring, and a guide sleeve is commonly installed between several fixing rods.

[0012] Furthermore, the vibration sampling assembly includes a vibration motor fixedly mounted on the top of the mounting plate, the top of the vibration motor is fixedly connected to the counterweight block, the bottom of the vibration motor is fixedly mounted with a sampling tube that passes through the mounting plate, and the guide sleeve sliding sleeve is arranged on the outside of the sampling tube.

[0013] Furthermore, the tripod assembly includes three support rods hinged on the outside of the mounting ring and distributed in a circle, a sliding sleeve is provided on the outside of the sampling tube, a connecting rod 1 and a connecting rod 2 are hinged on one side of the support rod close to the sliding sleeve, the connecting rod 1 and the connecting rod 2 are hinged to each other, a spring telescopic rod is hinged on the bottom of the fixed plate, the spring telescopic rod is hinged to the connecting rod 2, and when the support rod is in the unfolded state, the hinge point of the spring telescopic rod and the connecting rod 2 is farther away from the sampling tube than the hinge point of the connecting rod 1 and the connecting rod 2.

[0014] Furthermore, the soil-piercing assembly includes a mounting sleeve hinged at the bottom end of the support rod and a mounting rod fixedly installed in the mounting sleeve, a horizontal support plate fixedly installed at the bottom end of the mounting rod for contacting the ground so that the sampling tube is perpendicular to the ground, a plurality of vertical pointed feet fixedly installed at the bottom of the horizontal support plate, an inclined pointed foot fixedly installed on the side of the vertical pointed foot away from the mounting ring, and the tip of the inclined pointed foot is inclined upward.

[0015] Furthermore, the control assembly includes a reset spring fixedly mounted on a side of the fixed plate away from the counterweight block and a reset plate fixedly mounted on the other end of the reset spring.

[0016] Furthermore, a slot is provided on one side of the guide slide block 2 close to the fixed plate, and an insertion rod is fixedly installed on one side of the reset plate close to the counterweight block, which slides through the fixed plate and matches with the slot.

[0017] Furthermore, the pulling assembly includes an L-shaped mounting frame fixedly mounted on the side of the fixed plate away from the counterweight block, and two fixed pulleys are rotatably mounted on the mounting frame, one of which is located on the right side of the reset plate, and the other is located below the reset plate, and a pull rope is commonly wound around the outer sides of the two fixed pulleys.

[0018] Furthermore, an annular groove is provided at the hinge between the support rod and the mounting ring, the top end of the pull rope is fixedly connected to the reset plate, and the bottom end of the pull rope is fixedly installed in the annular groove after passing through the hinge axis between the support rod and the mounting ring. When the support rod is unfolded, the pull rope will be pulled downward.

[0019] Furthermore, a cylinder is fixedly mounted on the bottom of the mounting ring via a bottom plate, and an ear plate fixedly connected to an output end of the cylinder is fixedly mounted on the outer side of the sliding sleeve.

[0020] The beneficial effects of the present invention are: 1. The present application provides a stable downward force to the vibration sampling component by setting a counterweight block that can be automatically unlocked and naturally falls under the action of gravity, thereby eliminating the need for workers to manually apply downward force during the sampling process, reducing the labor intensity of the workers, and the continuous falling of the counterweight block ensures that the sampling tube is always subjected to uniform downward pressure during the process of entering the soil, which is more stable than the downward pressure applied by the workers, thereby improving the success rate and quality of sampling.

[0021] 2. During the vibration sampling process of the present application, the bottom end of the support rod will gradually rotate slightly outward with the vibration, thereby squeezing the inclined pointed foot outward, causing the inclined pointed foot to be subjected to an outward squeezing force in the horizontal direction, further penetrating into the soil, increasing the contact area and friction with the soil, and then as the vibration sampling proceeds, the support of the tripod assembly will become more and more stable, greatly improving the stability of the entire vibration sampling process.

[0022] 3. The present application utilizes the force generated by the rotation of the support rod to drive the pull rope to pull the reset plate to drive the insertion rod to disengage from the slot, thereby achieving automatic unlocking of the counterweight assembly, thereby improving the sampling efficiency while improving the automation level of the self-unlocking counterweight unit.

[0023] 4. In the sampling process, the present application guides the counterweight block in the vertical direction through a pair of guide sliders, guides the vibration motor in the vertical direction through a second guide slider, and guides the sampling tube in the vertical direction through a guide sleeve and a sliding sleeve, thereby forming a multi-level vertical guide reinforcement, so that the counterweight block, the vibration motor and the sampling tube can all move downward stably in a vertical state, thereby ensuring that the path of the sampling tube in the soil is a straight line, avoiding the problem of sampling failure caused by path deviation due to inclined insertion, and thus greatly improving the sampling accuracy.

[0030] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0031] See also Figure 1 and Figure 2 In this embodiment, a contaminated soil treatment sampling device is proposed, including a mounting ring 1, a multi-stage guide shock unit 4 and a side-piercing tripod unit 2 respectively arranged on the upper and lower sides of the mounting ring 1, wherein the multi-stage guide shock unit 4 includes a multi-stage guide component 401 and a shock component 402 arranged on the multi-stage guide component 401, and the side-piercing tripod unit 2 includes a tripod component 201 and a soil piercing component 202 for fixing the tripod component 201, and the multi-stage guide shock unit 4 is provided with The self-unlocking counterweight unit 5 includes a counterweight assembly 501 for providing downward pressure to the shock-taking assembly 402, a control assembly 502 and a pulling assembly 503 for pulling the control assembly 502, the control assembly 502 is used to cooperate with the tripod assembly 201 to fix and unlock the counterweight assembly 501, the multi-stage guide assembly 401 includes a plurality of fixed plates 4011 fixedly mounted on the inner wall of the mounting ring 1 and distributed in a circle, and the shock-taking assembly 402 includes a sampling tube 4022.

[0032] See also Figure 1 , Figure 4 and Figure 5 The tripod assembly 201 includes three support rods 2011 hinged on the outside of the mounting ring 1 and distributed in a circle, a sliding sleeve 2015 is provided on the outer sliding sleeve of the sampling tube 4022, and a connecting rod 1 2012 and a connecting rod 2013 are hinged on the side close to the support rod 2011 and the sliding sleeve 2015 respectively, and the connecting rod 1 2012 and the connecting rod 2 2013 are hinged to each other, and a spring telescopic rod 2014 is hinged on the bottom of the fixed plate 4011, and the spring telescopic rod 2014 is hinged to the connecting rod 2 2013, and the hinge point of the spring telescopic rod 2014 and the connecting rod 2 2013 when the support rod 2011 is in the unfolded state is farther away from the sampling tube 4022 than the hinge point of the connecting rod 1 2012 and the connecting rod 2 2013.

[0033] See also Figure 1 , Figure 4 and Figure 5 The soil-piercing assembly 202 includes a mounting sleeve 2021 hinged at the bottom end of the support rod 2011 and a mounting rod 2022 fixedly installed in the mounting sleeve 2021. A horizontal support plate 2023 for contacting the ground so that the sampling tube 4022 is perpendicular to the ground is fixedly installed at the bottom end of the mounting rod 2022. A plurality of vertical pointed feet 2024 are fixedly installed at the bottom of the horizontal support plate 2023. An inclined pointed foot 2025 is fixedly installed on the side of the vertical pointed foot 2024 away from the mounting ring 1, and the tip of the inclined pointed foot 2025 is tilted upward.

[0034] See also Figure 1 and Figure 4 The cylinder 3 is fixedly mounted on the bottom of the mounting ring 1 through a base plate 6, and an ear plate 7 fixedly connected to the output end of the cylinder 3 is fixedly mounted on the outer side of the sliding sleeve 2015.

[0035] When in use, the staff grasps the fixing plate 4011, places the shock assembly 402 perpendicular to the ground, and then starts the cylinder 3. The output end of the cylinder 3 contracts, driving the ear plate 7 to move upward, thereby driving the sliding sleeve 2015 to slide upward, and then driving the top of the second connecting rod 2013 to press upward on the hinge point between it and the spring telescopic rod 2014, thereby driving the spring telescopic rod 2014 to rotate toward the side close to the support rod 211 and gradually extend, pushing the second connecting rod 2013 to rotate downward, thereby causing the second connecting rod 2013 to squeeze The hinge point between it and the connecting rod 2012 drives the connecting rod 2012 to push the support rod 2011 to rotate outward and unfold, thereby making the tripod assembly 201 unfold as a whole. At the same time, during the overall unfolding process of the tripod assembly 201, the control assembly 502 is pulled by the pulling assembly 503 to unlock the counterweight assembly 501, and then the counterweight assembly 501 slides downward under the action of gravity and squeezes the shock-taking assembly 402 downward, driving the shock-taking assembly 402 to fall vertically to the ground under the guidance of the multi-stage guide assembly 401.

[0036] Then the staff presses down the three horizontal support plates 2023 and inserts the vertical pointed feet 2024 and the inclined pointed feet 2025 into the soil of the groove. During the insertion process, the inclined pointed feet 2025 will form a wedge effect when entering the soil, so that the soil is pushed away, thereby reducing the resistance required for insertion, so that the vertical pointed feet 2024 and the inclined pointed feet 2025 can smoothly penetrate the soil, thereby achieving the fixation of the vibration component 402. The horizontal support plates 2023 are supported on the ground, which increases the contact area between the tripod component 201 and the ground, so that the pressure of the support rod 2011 on the ground is more evenly dispersed, reducing the situation of excessive local pressure, avoiding the sinking or sliding of the support point, which causes the vibration to tilt during the vertical downward sampling process, and improves the sampling stability. At the same time, after the inclined pointed feet 2025 are inserted into the soil, lateral resistance is formed to resist the action of external lateral forces, thereby effectively preventing the lateral movement of the tripod component 201.

[0037] Then, the vibration component 402 is inserted into the soil for sampling, and as the vibration component 402 continues to vibrate downward for sampling, downward pressure is applied to the mounting ring 1 and transmitted to the support rod 2011. When the support rod 2011 is subjected to downward pressure, it rotates with its hinge point with the mounting ring 1 as the fulcrum (because the vertical pointed foot 2024 and the inclined pointed foot 2025 have been inserted into the soil at this time, and the horizontal support plate 2023 is in contact with the ground, the support rod 2011 is only slightly rotated at this time), so that the bottom end of the support rod 2011 rotates slightly outward, thereby squeezing the inclined pointed foot 2025 outward, so that the inclined pointed foot 2025 is pressed downward. The pointed feet 2025 are subjected to an outward extrusion force in the horizontal direction (it should be noted that: because the rotation range of the support rod 2011 is very limited, the rotation angle is very small, and the soil will exert friction and resistance on the vertical pointed feet 2024, the actual activity space of the vertical pointed feet 2024 will not be significantly increased as a result), and further penetrate into the soil, increasing the contact area and friction with the soil. As the vibration sampling proceeds, the support of the tripod assembly 201 will become more and more stable, greatly improving the stability of the entire vibration sampling process, until the vibration sampling assembly 402 is inserted into the soil to the required sampling depth and the sampling is completed.

[0038] See also Figure 2 and Figure 3 A guide slot 4012 is provided on a side close to several fixing plates 4011, and the counterweight assembly 501 includes a second guide slider 5011 slidably connected in the guide slot 4012, and a counterweight block 5012 is installed between several second guide sliders 5011.

[0039] See also Figure 2 and Figure 3The control component 502 includes a reset spring 5021 fixedly installed on the side of the fixed plate 4011 away from the counterweight block 5012 and a reset plate 5022 fixedly installed on the other end of the reset spring 5021. A slot 5024 is provided on the side of the guide slider 5011 close to the fixed plate 4011, and a plug rod 5023 is fixedly installed on the side of the reset plate 5022 close to the counterweight block 5012, which slides through the fixed plate 4011 and cooperates with the slot 5024.

[0040] See also Figure 2 , Figure 3 and Figure 5 The pulling assembly 503 includes an L-shaped mounting frame 5031 fixedly mounted on the fixed plate 4011 away from the counterweight block 5012, and two fixed pulleys 5032 are rotatably mounted on the mounting frame 5031, one of the fixed pulleys 5032 is located on the side of the reset plate 5022 away from the fixed plate 4011, and the other fixed pulley 5032 is located below the reset plate 5022, and a pull rope 5033 is wound around the outer sides of the two fixed pulleys 5032, and an annular groove 5034 is provided at the hinge between the support rod 2011 and the mounting ring 1, the top end of the pull rope 5033 is fixedly connected to the reset plate 5022, and the bottom end of the pull rope 5033 is fixedly mounted in the annular groove 5034 after passing through the hinge axis of the support rod 2011 and the mounting ring 1, and the pull rope 5033 will be pulled downward when the support rod 2011 is unfolded.

[0041] When in use, during the overall unfolding of the tripod assembly 201, the support rod 2011 rotates outward with the hinge axis with the mounting ring 1 as the center, and the pull rope 5033 is pulled downward synchronously. At the same time, the downward pulling force is converted into horizontal pulling force under the action of the two fixed pulleys 5032, thereby pulling the reset plate 5022 to drive the insertion rod 5023 to move away from the fixed plate 4011 and stretch the reset spring 5021, thereby driving the insertion rod 5023 to disengage from the slot 5024, so as to unlock the guide slider 2 5011 and the counterweight block 5012. The force generated by the rotation and expansion of the support rod 2011 drives the pull rope 5033 to pull the reset plate 5022, causing the insertion rod 5023 to disengage from the slot 5024, thereby realizing the automatic unlocking of the counterweight assembly 501, thereby improving the sampling efficiency while improving the degree of automation of the self-unlocking counterweight unit 5. Then, under the action of gravity, the counterweight block 5012 drives the guide slider 2 5011 to slide vertically downward along the guide slot 4012. The downward sliding of the counterweight block 5012 will squeeze the shock-taking assembly 402 downward, driving the shock-taking assembly 402 to fall vertically to the ground under the guidance of the multi-stage guide assembly 401.

[0042] See also Figure 1 , Figure 2 and Figure 4The multi-stage guide assembly 401 also includes a guide slider 4013 slidably connected in the guide groove 4012, a mounting plate 4014 is commonly installed between a plurality of guide sliders 4013, a plurality of circumferentially distributed fixing rods 4015 are fixedly installed on the inner side of the mounting ring 1, and a guide sleeve 4016 is commonly installed between the plurality of fixing rods 4015. It should be noted that, in order to reduce friction, balls are embedded in the guide slider 4013 and the guide slider 2 5011, and rolling friction is performed between the guide slider 4013 and the guide slider 2 5011 and the guide groove 4012 through the balls.

[0043] See also Figure 1 , Figure 2 and Figure 4 The vibration extraction assembly 402 also includes a vibration motor 4021 fixedly mounted on the top of the mounting plate 4014. The top of the vibration motor 4021 is fixedly connected to the counterweight block 5012. The sampling tube 4022 is fixedly mounted on the bottom of the vibration motor 4021 and fixedly passes through the mounting plate 4014. The guide sleeve 4016 is slidably mounted on the outside of the sampling tube 4022.

[0044] When in use, after the vertical pointed foot 2024 and the inclined pointed foot 2025 are inserted into the soil of the groove, the staff starts the vibration motor 4021, and the unbalanced rotor inside the vibration motor 4021 starts to rotate, generating high-frequency vibration in the vertical direction and transmitting it to the sampling tube 4022 through the mounting plate 4014, so that the sampling tube 4022 generates high-frequency up and down vibration in the vertical direction. Under the action of gravity, the counterweight block 5012 applies a stable downward pressure to the vibration motor 4021 and the sampling tube 4022 through the mounting plate 4014. Under the combined action of the downward pressure and the vibration assistance, the sampling tube 4022 continuously moves downward and is inserted into the soil. In this process, the guide slider 1 4013 is guided along the guide slot 4 012 slides vertically downward to guide the counterweight 5012 in the vertical direction, the guide slider 5011 guides the vibration motor 4021 in the vertical direction, the guide sleeve 4016 and the sliding sleeve 2015 guide the sampling tube 4022 in the vertical direction, thereby forming a multi-level vertical guide reinforcement, the counterweight 5012, the vibration motor 4021 and the sampling tube 4022 can all stably move downward in a vertical state, thereby ensuring that the path of the sampling tube 4022 in the soil is a straight line, avoiding the problem of sampling failure caused by path deviation due to inclined insertion, and thus greatly improving the sampling accuracy, until the sampling tube 4022 is inserted into the soil to the required sampling depth to complete the sampling.

[0045] After the sampling is completed, the staff holds the counterweight 5012 and pushes the counterweight 5012 upward, thereby driving the vibration motor 4021 and the sampling tube 4022 to move upward, pulling the sampling tube 4022 out of the soil and driving the guide slider 2 5011 to move to the top of the guide slide 4012 through the counterweight 5012, then pulling the vertical pointed foot 2024 and the inclined pointed foot 2025 out of the soil, and then, the output end of the cylinder 3 pushes the ear plate 7 to move downward, thereby driving the sliding sleeve 2015 to move downward, and then driving the connecting rod 2 The hinge point of 2013 and the sliding sleeve 2015 moves downward, causing the spring telescopic rod 2014 to rotate and shrink away from the support rod 2011, thereby causing the support rod 2011 to rotate toward the sampling tube 4022, and then the tripod assembly 201 is retracted. During the rotation of the support rod 2011 toward the sampling tube 4022, the tension on the reset spring 5021 gradually decreases, causing it to shrink and reset, and then the insertion rod 5023 is driven by the reset plate 5022 to be reinserted into the slot 5024 to fix the counterweight block 5012.

[0046] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
