Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling inspection, in particular to a sampling inspection device for soil remediation. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. In the soil remediation industry, there are more than 100 existing soil remediation technologies and more than 10 commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. During the soil remediation process, sampling equipment is needed to conduct multi-point sampling of the remediated soil to check the soil remediation status.

[0003] A Chinese patent (CN220398945U) discloses a soil sampling device for environmental quality inspection, comprising a sampling device body and side vertical rods arranged on the left and right sides of the paper sampling device body, a side support rod is installed at one end of the side vertical rod away from the sampling device body, an end of the side vertical rod close to the sampling device body is fixedly connected to an electric guide rail, an output end of the electric guide rail is fixedly connected to a vertical moving rod, a slide groove is provided on the upper side of the vertical moving rod close to the sampling device body, a pallet rack is arranged on the lower side of one end of the vertical moving rod close to the sampling device body and the output end of the slide groove, and the two pallet racks are slidably connected to the corresponding slide grooves.

[0004] Although the above scheme can offset the vibration force generated when the driving machine starts by the shock absorber to achieve the effect of improving the stability of the downward movement of the sampling device body; however, in this scheme, when it is necessary to change the next sampling point, the soil sampling device described in this scheme needs to be moved. If the sampling device body is removed from between the side vertical rods for moving, after moving to the next sampling point, the sampling device body needs to be reinstalled between the two side vertical rods, which is very troublesome to operate. If the soil sampling device described in this scheme is moved as a whole, it is necessary to keep the soil sampling device in this scheme in a nearly vertical state for moving to prevent the sampling device body from falling out from between the two side vertical rods. However, in the process of keeping the soil sampling device in this scheme in a nearly vertical state for moving, it is easy to make the soil sampling device in this scheme be lifted too low, causing the lower end of the fixed rod to scrape the ground, which is easy to trip the carrier.

In this embodiment, there are three fixed rods 4, and correspondingly, there are also three elastic members 5. It can be understood that in other embodiments, the fixed rods 4 and the elastic members 5 can also be other numbers, and it is only necessary to ensure that the number of the fixed rods 4 and the elastic members 5 is the same and one-to-one corresponding. In this embodiment, there are two rollers 3. It can be understood that in other embodiments, the rollers 3 can also be other numbers.

[0030] The initial state of the soil remediation sampling device of the utility model is as follows: the elastic member 5 supports the fixing rod 4 upward, and the lower end of the fixing rod 4 is higher than the lower end of the roller 3 .

[0031] Before using the soil remediation sampling device of the present invention to collect soil: place the soil remediation sampling device of the present invention at the sampling point. Then press down the fixing rod 4 to insert the lower end of the fixing rod 4 into the soil. In the process of pressing down the fixing rod 4, the elastic member 5 is compressed (see Figure 3 At this time, the soil remediation sampling device of the utility model has good stability and is not prone to horizontal movement.

[0032] When using the soil remediation sampling equipment described in the utility model to collect soil: start the sampling drill 1, and apply a vertical downward force to the sampling drill 1, so that the sampling drill 1 slides downward relative to the frame 2, so that the lower end of the sampling drill 1 is inserted into the soil to collect the soil; after completing the soil collection, apply an upward force to the sampling drill 1 to pull the lower end of the sampling drill 1 out of the soil, and the lower end of the sampling drill 1 will bring out the collected soil, and then pull the lower end of the fixed rod 4 out of the soil, the elastic member 5 elastically resets to the initial state, and the lower end of the fixed rod 4 is restored to be higher than the lower end of the roller 3. At this time, the soil sampling of the sampling point is completed.

[0033] When it is necessary to move the soil remediation sampling equipment described in the utility model to the next sampling point: stabilize the frame 2 and pull the frame 2, so that the soil remediation sampling equipment described in the utility model can be moved as a whole. In the process of pulling the frame 2, the roller 3 can roll and support the frame 2, which is more labor-saving when pulling the frame 2. Under the support of the elastic member 5, the lower end of the fixed rod 4 is higher than the lower end of the roller 3. When moving the soil remediation sampling equipment described in the utility model, the lower end of the fixed rod 4 is not easy to scratch the ground, which can reduce the possibility of the carrier being tripped.

[0034] In this embodiment, the frame 2 includes a base plate 6 and a mounting frame 7. The base plate 6 is provided with a first through hole for the lower end of the sampling drill 1 to pass through at a position corresponding to the lower end of the sampling drill 1. The base plate 6 is provided with a second through hole at a position corresponding to the fixed insertion rod 4. The sampling drill 1 can be slidably arranged on the mounting frame 7 up and down, and the roller 3 can be rotatably arranged on the lower side of the base plate 6. The fixed insertion rod 4 is slidably fitted in the second through hole. The lower end of the elastic member 5 is supported on the base plate 6, and the upper end of the elastic member 5 supports the fixed insertion rod 4 upward.

[0035] Since the sampling drill 1 can be slidably arranged on the mounting frame 7, the sampling drill 1 is slid downward on the mounting frame 7 so that the lower end of the sampling drill 1 passes through the first through hole and is inserted into the soil. With this structure, the sampling drill 1 can be slidably arranged on the frame 2, and the lower end of the sampling drill 1 can be inserted downward into the soil. Since the fixed insertion rod 4 is slidably fitted in the second through hole, with this structure, the fixed insertion rod 4 can be slidably arranged on the lower end of the frame 2. Since the lower end of the elastic member 5 supports the bottom plate 6, and the upper end of the elastic member 5 supports the fixed insertion rod 4 upward, with this structure, the elastic member 5 can be arranged on the frame 2 and support the fixed insertion rod 4 upward.

[0036] In this embodiment, a locking part is further included, and the locking part is fixed on the bottom plate 6. The locking part is used to lock the position of the fixing rod 4 after the lower end of the fixing rod 4 is inserted into the soil. In this embodiment, there are three locking parts. It can be understood that in other embodiments, the locking parts can also be other numbers, as long as the number of the locking parts and the fixing rod 4 is the same and one-to-one corresponding.

[0037] After the fixing rod 4 slides downward and is inserted into the soil, the locking portion locks the fixing rod 4 to keep it inserted into the soil, thereby preventing the fixing rod 4 from being pulled out of the soil upward under the elastic force of the elastic member 5 .

[0038] In this embodiment, the locking portion includes a cylinder 8 fixedly mounted on the upper side surface of the base plate 6, the cylinder 8 and the second through hole are arranged coaxially, the upper end of the cylinder wall of the cylinder 8 is recessed downward to form a first notch 9, and the lower end of a side wall of the first notch 9 is recessed along the circumferential direction of the cylinder 8 to form a second notch 10; the fixed insertion rod 4 includes an insertion rod body 11 and a buckle block 12, the insertion rod body 11 is located in the cylinder 8, the buckle block 12 is fixedly mounted on the outer surface of the insertion rod body 11, the buckle block 12 is located above the cylinder 8, the buckle block 12 is adapted to both the first notch 9 and the second notch 10, and when the buckle block 12 is located in the first notch 9 and facing the second notch 9, the lower end of the insertion rod body 11 is located in the soil.

[0039] Before inserting the rod body 11 downward into the soil, rotate the rod body 11 in the second through hole so that the buckle block 12 faces the first notch 9. Then apply a downward force to the rod body 11 to move the rod body 11 downward. When the buckle block 12 moves into the first notch 9 and faces the second notch 10, stop the rod body 11 from moving downward. At this time, the lower end of the rod body 11 is located in the soil. Then rotate the rod body 11 so that the buckle block 12 rotates with the rod body 11 into the second notch 10. At this time, the fixed rod 4 can be locked and cannot move upward. With this structure, the locking portion can lock the position of the fixed rod 4 after the lower end of the fixed rod 4 is inserted into the soil.

[0040] In this embodiment, the elastic member 5 is a coil spring, which is sleeved on the plug rod body 11 , with the lower end of the coil spring abutting against the bottom plate 6 , and the upper end of the coil spring abutting against the buckle block 12 .

[0041] With this structure, the elastic member 5 can be arranged on the frame 2 and support the fixing rod 4 upwards. When the fixing rod 4 is pressed down, the elastic member 5 can be compressed.

[0042] In this embodiment, the fixing rod 4 further includes a pressing plate 13 , and a collar 14 is connected to the upper end of the pressing plate 13 . The inner cavity of the collar 14 is used to accommodate the foot of the user.

[0043] When the fixing rod 4 needs to be inserted downward into the soil or the fixing rod 4 needs to be pulled upward from the soil, the carrier puts his feet into the ring 14, and the carrier can use his feet to press down, rotate and lift the fixing rod 4 without bending down and using his hands to press down, rotate or lift the fixing rod 4, which is more convenient when it is necessary to press down, rotate or lift the fixing rod 4.

[0044] In this embodiment, the roller 3 is located at the left part of the lower end of the bottom plate 6, and the rotation axis of the roller 3 is arranged along the front-back direction. The frame 2 also includes a foot 15 arranged on the lower side of the bottom plate 6. The foot 15 is arranged on the right part of the lower side of the bottom plate 6, and the lower end of the foot 15 is at the same height as the lower end of the roller 3. In this embodiment, there are two feet 15, and it can be understood that in other implementations, the number of feet 15 can also be other numbers.

[0045] The roller 3 is arranged on the left part of the lower side of the bottom plate 6, and the foot 15 is arranged on the right part of the lower side of the bottom plate 6, and its lower end is at the same height as the lower end of the roller 3. The roller 3 and the foot 15 jointly support the bottom plate 6, so that the frame 2 can be supported on the ground more stably.

[0046] When the soil remediation sampling device of the utility model needs to be moved, the lower end of the frame 2 is kept stationary, and the upper end of the frame 2 is pulled to the left, so that the upper end of the frame 2 is in a state of tilting to the left. At this time, the foot 15 can be separated from the ground, and only the roller 3 is left to support the frame 2 (see Figure 4 As shown), the rack 2 can be stabilized and pulled.

[0047] In this embodiment, the mounting frame 7 includes a plurality of guide rods 16, which are vertically fixed on the base plate 6; it also includes the loading part, which is used to install the sampling drill rig 1, and the loading part can be slidably arranged on the plurality of guide rods 16 up and down.

[0048] Since the loading part is used to install the sampling drill 1, the loading part can be slidably arranged on the plurality of guide rods 16, and after the sampling drill 1 is installed on the loading part, the sampling drill 1 can be slidably arranged on the plurality of guide rods 16. With this structure, the sampling drill 1 can be slidably arranged on the mounting frame 7.

[0049] In this embodiment, the sampling drill 1 includes a machine body 17 and a sampling drill rod 18, the sampling drill rod 18 is fixedly arranged at the lower end of the machine body 17, and the lower end of the sampling drill rod 18 is used to be inserted downward into the soil to collect soil samples; the loading part includes a sliding sleeve 19, a first carrier plate 20, a side plate 21, a second carrier plate 22, a baffle 24 and a bolt 26, the sliding sleeve 19 is multiple, and the multiple sliding sleeves 19 are slidably matched on the multiple guide rods 16 in a one-to-one correspondence, the first carrier plate 20 is arranged between the multiple guide rods 16, the first carrier plate 20 and the multiple sliding sleeves 19 are fixedly connected, the side plate 21 is two, and the upper ends of the two side plates 21 are fixedly connected to the first carrier plate 20 The lower side surface of the two side plates 21 are respectively located on the front and rear sides of the second carrier plate 22, and the lower ends of the right sides of the two side plates 21 are provided with thread grooves 25. The second carrier plate 22 is connected between the lower ends of the two side plates 21 in a manner that can slide in the left and right directions. The second carrier plate 22 is penetrated by a third through hole for the sampling drill rod 18 to pass downward. The baffle plate 24 is fixed to the right end of the second carrier plate 22. The baffle plate 24 is provided with fourth through holes at positions corresponding to the two thread grooves 25. There are two bolts 26, and the two bolts 26 are respectively located in the two fourth through holes. The screw-in ends of the two bolts 26 are respectively used to be screwed with the two thread grooves 25.

[0050] The first carrier plate 20 is slidably connected to the multiple guide rods 16 via the multiple sliding sleeves 19. With this structure, the loading part can be slidably arranged on the multiple guide rods 16. The guide rods 16 can guide the sliding of the sliding sleeves 19 to ensure the stability of the loading part sliding up and down.

[0051] When the sampling drill 1 needs to be installed on the loading part, first pull the second carrier plate 22 horizontally toward the right end of the frame 2 until the second carrier plate 22 exposes an area for placing the machine body 17, lift the sampling drill 1 and insert the sampling drill rod 18 at the lower end of the sampling drill 1 downward into the third through hole (see Figure 5 As shown in the figure, the machine body 17 can be placed on the upper side of the second carrier plate 22. Then the second carrier plate 22 is pushed horizontally toward the left end of the frame 2 until the baffle plate 24 and the side plate 21 are against each other, and the machine body 17 is located between the two side plates 21. The two bolts 26 are respectively screwed with the corresponding thread grooves 25, so that the baffle plate 24 and the two side plates 21 can be connected and fixed, and the second carrier plate 22 can be fixed between the two side plates 21.
