Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to a sample collection device for soil remediation. Background Technology

[0002] Soil remediation refers to technical measures that restore contaminated soil to its normal function. It involves reducing the concentration of pollutants in the soil through physical, chemical, or biological methods to render the pollutants harmless and stabilize them, thereby achieving a detoxification effect.

[0003] In the preliminary work of soil remediation, a sampling device is used to sample the soil to be remediated and to analyze and test the soil quality to propose targeted remediation operations.

[0004] For example, utility model application No. 202320521201.0 discloses a soil remediation sample collection device. This sample collection device, through the structural design of four collection plates, allows for quick and convenient soil removal when soil needs to be removed. The rotating sleeve moves downward, pressing the vertical column downward. The vertical column, through a ball, presses a folded plate to rotate around a pivot. The folded plate can drive the collection plates to rotate, thereby opening the four collection plates and allowing the soil to fall out. This achieves the function of quick and convenient soil removal, solving the problem that current soil sample collection devices are inconvenient to remove soil from the sampling tube. However, similar sample collection devices in the above-mentioned document have relatively complex structures and large overall weight, making them relatively inconvenient to carry. At the same time, due to the complexity of the design, the overall production cost is relatively high.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its deficiencies, and proposed a sample collection device for soil remediation. Utility Model Content

[0006] The purpose of this invention is to provide a sample collection device for soil remediation, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sample collection device for soil remediation, comprising a support plate and a device frame. An adjusting push rod is vertically threaded in the middle of the support plate, and support rods are vertically threaded at the four diagonal corners of the bottom of the support plate. Two sets of support frames are slidably connected to the middle section surface of the support rods. The device frame is connected and installed at the bottom end of the adjusting push rod, and sampling inserts are connected around the perimeter of the device frame. The device frame includes a stabilizing column, a cross, a connecting pile, and a fixing bolt. Crosses are installed at both the upper and lower ends of the stabilizing column, and a connecting pile is vertically installed in the middle of the upper cross. A fixing bolt is horizontally inserted through the middle of the connecting pile.

[0008] Furthermore, the support plate includes a device plate, a rotating pile, and a docking pile. A rotating pile is vertically installed in the middle of the device plate, and docking piles are installed at the four corners of the bottom of the device plate.

[0009] Furthermore, the adjusting push rod includes a screw rod, a hand wheel, and a fixing hole. A hand wheel is installed at the top end of the screw rod, and a fixing hole is horizontally opened at the lower end of the screw rod. The screw rod vertically passes through the middle of the rotating pile in a threaded manner.

[0010] Furthermore, the support rod includes a main rod body, connecting threads, and a plug. Connecting threads are provided on the upper surface of the main rod body, and a plug is installed at the bottom end of the main rod body.

[0011] Furthermore, the plug is threadedly connected to the main rod body, and the main rod body is threadedly connected to the docking pile through the connecting threads. The support frame is arranged in a "囗" shape structure, and sleeve structures are provided at the four corners of the support frame to vertically penetrate the main rod body.

[0012] Furthermore, the fixing bolt is threadedly connected to the inside of the fixing hole. Four groups of stabilizing columns are installed in a circular array centered on the cross. The lower end of the screw rod is vertically inserted into the inside of the connecting pile.

[0013] Furthermore, the sampling plug board includes a sampling arc board, quick connectors, and an inverted board. Quick connectors are installed at the upper and lower ends of the side of the sampling arc board close to the device frame, and an inverted board is connected to the lower end of the side of the sampling arc board close to the device frame.

[0014] Furthermore, four groups of sampling plug boards are installed in a circular array centered on the cross, and one end of the cross is threadedly connected to the quick connector.

[0015] The present utility model provides a sample taking device for soil remediation, which has the following beneficial effects:

[0016] 1. This utility model adopts a modular structure for the support plate, adjusting push rod, support rod, support frame, device frame, and sampling insert plate. This allows for flexible assembly and disassembly while ensuring sufficient structural support after assembly. In use, simply screw the adjusting push rod vertically into the middle of the support plate, then screw the four sets of support rods to the bottom diagonal of the support plate. Next, vertically insert the bottom end of the adjusting push rod into the middle of the top of the device frame and secure it with fixing bolts. Finally, assemble the sampling insert plates using quick-connect couplings and cross-shaped threaded connections to complete the assembly. This structure allows for flexible disassembly of the device for easy transport and facilitates mass production. The modular design helps control production costs. When the device is damaged, only the damaged components need to be disassembled and replaced, thus enabling convenient maintenance.

[0017] 2. This utility model features a support frame that slides onto the surface of the support rod. The number of support frames can be adjusted according to the vertical depth of the support rod inserted into the soil. The support frame structure provides structural support and limits the four sets of support rods, preventing structural displacement and ensuring the stability of the entire device after insertion into the soil. This allows the device frame and sampling plate connected to its bottom to be stably screwed into the soil when the push rod is rotated and adjusted. Furthermore, the sampling arc plate uses a quick-connect fitting on one side to be threaded to one end of the cross, facilitating disassembly and removal of the sampled soil from between the device frame and sampling plate. This also facilitates subsequent cleaning of the device frame and sampling plate, ensuring the device's ease of use, flexibility, and stability. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] like Figures 1 to 6 As shown, a sample collection device for soil remediation includes a support plate 1 and a device frame 5. An adjusting push rod 2 is vertically threaded in the middle of the support plate 1, and support rods 3 are vertically threaded at the four diagonal corners of the bottom of the support plate 1. Two sets of support frames 4 are slidably connected to the middle section of the support rods 3. The device frame 5 is connected to the bottom end of the adjusting push rod 2, and sampling insert plates 6 are connected around the perimeter of the device frame 5. The device frame 5 includes a stabilizing column 501, a cross 502, a connecting pile 503, and fixing bolts 504. Cross 502s are installed at both the upper and lower ends of the stabilizing column 501, and a connecting pile 503 is vertically installed in the middle of the upper cross 502. The connecting pile 503... A fixing bolt 504 runs horizontally through the middle section. The fixing bolt 504 is threadedly connected to the inside of the fixing hole 203. Four sets of stabilizing columns 501 are installed in a circular array with the cross 502 as the center. The lower end of the screw rod 201 is vertically inserted into the inside of the connecting pile 503. When in use, simply screw the adjusting push rod 2 vertically into the middle of the support plate 1, then screw the four sets of support rods 3 to the bottom diagonal of the support plate 1, then vertically insert the bottom end of the adjusting push rod 2 into the middle of the top of the device frame 5, and connect and fix it with the fixing bolt 504. Finally, the sampling insert plate 6 is combined and connected with the cross 502 using the threaded connection structure of the quick connector 602 to complete the structural assembly.

[0027] like Figures 1 to 6As shown in the figure, the support plate 1 includes a device plate 101, a rotating pile 102 and a docking pile 103. A rotating pile 102 is vertically installed in the middle of the device plate 101, and docking piles 103 are installed at the four corners of the bottom of the device plate 101. The adjusting push rod 2 includes a screw rod 201, a hand wheel 202 and a fixing hole 203. A hand wheel 202 is installed at the top end of the screw rod 201, and a fixing hole 203 is horizontally opened at the lower end of the screw rod 201. The screw rod 201 vertically passes through the middle of the rotating pile 102 in a threaded manner. The support rod 3 includes a main rod body 301, a connecting thread 302 and a sampling rod 303. A connecting thread 302 is opened on the upper surface of the main rod body 301, and a sampling rod 303 is installed at the bottom end of the main rod body 301. The sampling rod 303 is threadedly connected with the main rod body 301, and the main rod body 301 is threadedly connected with the docking pile 103 through the connecting thread 302. The support frame 4 is arranged in a "囗" shape structure, and sleeve structures are provided at the four corners of the support frame 4 so that the main rod body 301 vertically passes through them. The sampling insertion plate 6 includes a sampling arc plate 601, a quick joint 602 and an inverted plate 603. Quick joints 602 are installed at the upper and lower ends of the side surface of the sampling arc plate 601 close to the device frame 5, and an inverted plate 603 is connected to the lower end of the side surface of the sampling arc plate 601 close to the device frame 5. Four groups of sampling insertion plates 6 are installed in a circular array with the cross 502 as the center, and one end of the cross 502 is threadedly connected with the quick joint 602. The sampling arc plate 601 is threadedly connected with one end of the cross 502 by using the quick joint 602 on one side surface, so that while the structures are easy to disassemble, it is convenient to take out the sampled soil from between the device frame 5 and the sampling insertion plate 6, and it is convenient to clean the surfaces of the device frame 5 and the sampling insertion plate 6 subsequently.

[0028] In summary, as Figures 1 to 6 shown in the figure, when using the sample-taking device for soil remediation, first, the sampling insertion plate 6 is structurally docked with one end of the cross 502 connected to the upper and lower ends of the stabilizing column 501 by using the quick joints 602 provided at the upper and lower ends of the side surface of the sampling arc plate 601. Then, by screwing the structure of the quick joint 602, the sampling insertion plate 6 can be quickly structurally docked and fixed with the device frame 5.

[0029] After using the above operations to complete the combination of the four groups of sampling insertion plates 6 and the device frame 5 in sequence, the main rod body 301 is vertically screwed into the interior of one of the docking piles 103 at the diagonal corners of the bottom of the device plate 101 from bottom to top by using the connecting thread 302 on the upper surface, so as to quickly dock and combine the four groups of support rods 3 with the support plate 1. After that, when the whole device needs to be inserted into the soil layer, only the four sampling rods 303 need to be screwed into the bottoms of the four groups of main rod bodies 301 respectively, so as to quickly and effectively carry out the insertion setting.

[0030] Then, the lead screw 201 can be vertically screwed into the interior of the rotating pile 102, and its thread can be passed through, so that the adjusting push rod 2 and the support plate 1 can be quickly combined. After the adjusting push rod 2 passes through the support plate 1, the bottom end of the lead screw 201 is vertically inserted into the interior of the connecting pile 503 at the top of the cross 502, and then used. The fixing bolt 504 is horizontally screwed into the interior of the connecting pile 503 and the fixing hole 203 in sequence, thereby connecting and fixing the device frame 5 and the adjusting push rod 2.

[0031] Finally, when using it, an appropriate number of support frames 4 can be prepared in advance, and four sets of support rods 3 can be vertically inserted into the sleeve structure at the four opposite corners of the support frame 4, so that the support rods 3 and the support frame 4 are structurally connected to ensure the structural stability of the support rods 3. After the entire device is inserted into the soil, the handwheel 202 at the top of the screw 201 is turned, thereby driving the device frame 5 and sampling plate 6 connected to the bottom of the screw 201 to rotate vertically from top to bottom and gradually enter the soil layer. The sampling arc plate 601 and the inverted plate 603 will rotate and cut the soil layer so that it can be extracted from the ground surface later.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
