Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a soil and rock sampling device for environmental monitoring in soil and rock areas. Background Technology

[0002] Environmental monitoring in geotechnical areas aims to ensure engineering safety, protect the environment, and study geological processes. Monitoring content covers the physical properties of soil and rock (deformation, stress, and strain), groundwater (water level and quality), soil environment (composition and pollution), and geological hazards (landslides and debris flows). Various monitoring methods are employed, including surface, underground, remote sensing, and geophysical monitoring. Monitoring frequency depends on the characteristics of the monitored object and engineering requirements, with higher frequency during construction and appropriately lower frequency during operation. The monitoring cycle is determined based on the engineering design service life and geological stability.

[0003] Sampling devices are used in the environmental monitoring of soil and rock areas to sample soil and rock. Publication number CN220251400U discloses a soil and rock sampling device, which "includes a base plate, with fixed rods fixedly connected to both sides of the top of the base plate, a fixed plate fixedly connected to the bottom of the fixed rods, a hydraulic cylinder mounted on the top of the fixed plate, a motor fixedly connected to the piston rod of the hydraulic cylinder passing through the bottom of the fixed plate, a sampling component located below the motor, and a fixing component located on the outside of the fixed rods… This facilitates the classification, sampling, and collection of soil, gravel, and fine sand in the sampled soil and rock, and allows staff to easily sample different types of soil and rock." This invention achieves the goal of improving the sampling efficiency of staff and facilitating their use by conducting separate tests. In the prior art, the sampling tube and the drive shaft of the motor are fixedly connected, which makes it impossible to remove the sampling tube separately after the sampling work is completed, thus making the cleaning of the sampling tube difficult. Moreover, its fixing mechanism is relatively simple, and it can only fix the device on a relatively flat ground. If sampling is carried out on an uneven ground, the device may tilt, which will affect the accuracy of the sampling. Therefore, this application proposes a soil and rock sampling device for environmental monitoring in soil and rock areas to meet the requirements. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices, such as the inconvenience of cleaning the sampling tube and the inability to keep it horizontal in different terrains, this utility model provides a soil and rock sampling device for environmental monitoring in soil and rock areas.

[0005] The technical implementation scheme of this utility model is as follows: a soil and rock sampling device for environmental monitoring in soil and rock areas, comprising a base plate, an inverted U-shaped mounting frame fixedly connected to the top of the base plate, a hydraulic rod mounted on the top of the mounting frame, a motor mounted at the bottom of the hydraulic rod, a drive shaft mounted at the bottom of the motor, a sampling cylinder arranged below the drive shaft, an installation assembly arranged between the sampling cylinder and the drive shaft, rollers mounted at the bottom of each of the four corners of the base plate, a support plate arranged on one side of each roller, a support fixedly connected to the bottom of the support plate, an adjustment assembly arranged at the connection between the support plate and the base plate, guide grooves opened on the inner walls of both sides of the mounting frame, and guide blocks slidably connected to the guide grooves fixedly connected to both sides of the motor.

[0006] Optionally, the mounting assembly includes a mounting ring, a mounting groove, a mounting hole, a cavity, a through groove, and a mounting block. The mounting ring is fixedly connected to the top of the sampling cylinder. The mounting groove passes through the middle of the mounting ring and is adapted to the size of the drive shaft. Several sets of mounting holes are provided and are opened on the outer periphery of the drive shaft near the bottom. The cavity is annular and is opened inside the mounting ring. The through groove passes through the inner wall of the cavity near the mounting groove. The mounting block is slidably connected to the through groove and is adapted to the size of the mounting hole.

[0007] Optionally, the mounting assembly further includes a rotating ring, a top block, a first sliding groove, a first slider, and a first spring. The rotating ring is rotatably connected to the cavity. The top block is fixedly connected to the side of the rotating ring near the mounting block, and the ends of the top block and the mounting block that are in contact with each other are arc-shaped. The first sliding groove is opened on one side of the mounting ring and communicates with the cavity. The first slider is fixedly connected to the rotating ring and slidably connected to the first sliding groove. The first spring is installed inside the first sliding groove, and its two ends are respectively fixedly connected to one side of the first slider and one side of the inner wall of the first sliding groove.

[0008] Optionally, the mounting assembly further includes a second slide groove, a second slider, and a second spring. The second slide groove is formed on the inner wall of the bottom of the cavity and is located below the mounting block. The second slider is fixedly connected to the bottom of the mounting block and slidably connected to the second slide groove. The second spring is installed inside the second slide groove and its two ends are respectively fixedly connected to the inner wall of the second slider away from the rotating ring and the second slide groove away from the rotating ring. The elastic force of the first spring is greater than the sum of the elastic forces of multiple sets of second springs.

[0009] Optionally, the adjustment assembly includes a mounting base, an adjustment groove, a fixing hole, a connecting groove, and a fixing rod. The mounting base is fixedly connected to the top of the base plate. The adjustment groove passes through the mounting base and the base plate and is adapted to the size of the support plate. Several sets of fixing holes are provided and pass through the support plate. The connecting groove passes through the inner wall of one side of the adjustment groove. The fixing rod is movably connected to the connecting groove and is adapted to the size of the fixing hole.

[0010] Optionally, the adjustment assembly further includes a third slide groove, a third slider, a third spring, and a pull block. The third slide groove is formed on the inner wall of the connecting groove. The third slider is fixedly connected to the outer periphery of the fixed rod and slidably connected to the third slide groove. The third spring is sleeved on the outer periphery of the fixed rod and its two ends are respectively fixedly connected to the inner wall of the third slider on the side away from the adjustment groove and the side of the third slide groove away from the adjustment groove. The pull block is fixedly connected to the outer end of the fixed rod.

[0011] This utility model has the following advantages:

[0012] 1. This utility model features an installation assembly. A first slider slides along a first groove, compressing a first spring. A rotating ring drives a top block to move synchronously within the cavity with the first slider. When the top block moves away from the rear of the mounting block, a second spring rebounds and, through the second slider, moves the mounting block towards the inner side of the cavity. When the mounting block is submerged in the through groove, the sampling cylinder is placed at the bottom of the drive shaft, aligning the drive shaft's mounting hole with the mounting block. The first slider is then released, and the first spring rebounds, driving the rotating ring and top block to move in opposite directions. When the top block contacts the mounting block, it pushes the mounting block towards the mounting groove. When the mounting block is inserted into the mounting hole, the drive shaft is fixed within the mounting groove, thus completing the installation of the sampling cylinder. This design allows for rapid installation and removal of the sampling cylinder, improving cleaning efficiency after sampling.

[0013] 2. This utility model features an adjustment component. Pulling the pull block outward causes it to slide the third slider along the third groove via the fixed rod, compressing the third spring. When the fixed rod moves out of the fixed hole, the support plate slides down the adjustment groove until the support is in close contact with the ground. Then, the pull block is released, the third spring rebounds, and the third slider moves the fixed rod inward. When the fixed rod is inserted into the fixed hole at the current height, the support plate is fixed at the current height. This design allows the device to remain fixed and level under different terrains, thus avoiding the inability to collect samples at accurate locations due to device tilt. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in this document are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] A soil and rock sampling device for environmental monitoring in soil and rock areas includes a base plate 1, an inverted U-shaped mounting frame 2 fixedly connected to the top of the base plate 1, a hydraulic rod 3 mounted on the top of the mounting frame 2, a motor 4 mounted at the bottom of the hydraulic rod 3, a drive shaft 5 mounted at the bottom of the motor 4, a sampling cylinder 6 disposed below the drive shaft 5, an installation assembly 7 disposed between the sampling cylinder 6 and the drive shaft 5, rollers 8 mounted at the bottom of each of the four corners of the base plate 1, a support plate 9 disposed on one side of each roller 8, a support 10 fixedly connected to the bottom of the support plate 9, an adjustment assembly 11 disposed at the connection between the support plate 9 and the base plate 1, guide grooves 12 opened on both sides of the inner wall of the mounting frame 2, and guide blocks 13 slidably connected to the guide grooves 12 fixedly connected to both sides of the motor 4.

[0023] It should be noted that the installation component 7 allows the sampling tube 6 to be quickly installed and disassembled, thereby improving the cleaning efficiency of the sampling tube 6 after use. The adjustment component 11 can keep the device level by adjusting the height of the support plate 9, thereby avoiding the device tilting and making it impossible to collect samples from the accurate location.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, the mounting assembly 7 includes a mounting ring 71, a mounting groove 72, a mounting hole 73, a cavity 74, a through groove 75, and a mounting block 76. The mounting ring 71 is fixedly connected to the top of the sampling cylinder 6. The mounting groove 72 passes through the middle of the mounting ring 71 and is adapted to the size of the drive shaft 5. The mounting hole 73 is provided in several sets and is opened on the outer periphery of the drive shaft 5 near the bottom. The cavity 74 is annular and is opened inside the mounting ring 71. The through groove 75 passes through the inner wall of the cavity 74 near the mounting groove 72. The mounting block 76 is slidably connected to the through groove 75 and is adapted to the size of the mounting hole 73.

[0025] It should be noted that the drive shaft 5 is placed in the mounting groove 72, and then the mounting block 76 is inserted into the mounting hole 73. At this time, the drive shaft 5 can be fixed in the mounting groove 72, thereby completing the connection between the sampling cylinder 6 and the drive shaft 5.

[0026] like Figure 3 As shown, the mounting assembly 7 also includes a rotating ring 77, a top block 78, a first sliding groove 79, a first slider 710, and a first spring 711. The rotating ring 77 is rotatably connected to the cavity 74. The top block 78 is fixedly connected to the side of the rotating ring 77 near the mounting block 76, and the ends of the top block 78 and the mounting block 76 that are in contact are both arc-shaped. The first sliding groove 79 is opened on one side of the mounting ring 71 and communicates with the cavity 74. The first slider 710 is fixedly connected to the rotating ring 77 and slidably connected to the first sliding groove 79. The first spring 711 is installed inside the first sliding groove 79 and its two ends are fixedly connected to one side of the first slider 710 and one side of the inner wall of the first sliding groove 79, respectively.

[0027] It should be noted that when the first slider 710 slides along the first groove 79 to compress the first spring 711, the rotating ring 77 will drive the top block 78 to move synchronously with the first slider 710 in the cavity 74. When the first slider 710 is released, the first spring 711 rebounds and can drive the rotating ring 77 and the top block 78 to move in the opposite direction through the first slider 710.

[0028] like Figure 4 As shown, the mounting assembly 7 also includes a second slide groove 712, a second slider 713, and a second spring 714. The second slide groove 712 is formed on the bottom inner wall of the cavity 74 and is located below the mounting block 76. The second slider 713 is fixedly connected to the bottom of the mounting block 76 and slidably connected to the second slide groove 712. The second spring 714 is installed inside the second slide groove 712 and its two ends are respectively fixedly connected to the inner wall of the second slider 713 away from the rotating ring 77 and the inner wall of the slide groove 712 away from the rotating ring 77. The elastic force of the first spring 711 is greater than the sum of the elastic forces of multiple sets of second springs 714.

[0029] It should be noted that when the first spring 711 is compressed, the top block 78 moves away from the rear of the mounting block 76. At this time, the second spring 714 rebounds and drives the mounting block 76 to move into the cavity 74 through the second slider 713. When the first spring 711 rebounds, since the elastic force of the first spring 711 is greater than the sum of the elastic forces of multiple sets of second springs 714, the top block 78 will push the mounting block 76 towards the mounting groove 72 and compress the second spring 714 through the second slider 713.

[0030] like Figure 5 and Figure 6 As shown, the adjustment assembly 11 includes a mounting base 111, an adjustment groove 112, a fixing hole 113, a connecting groove 114, and a fixing rod 115. The mounting base 111 is fixedly connected to the top of the base plate 1. The adjustment groove 112 passes through the mounting base 111 and the base plate 1 and is adapted to the size of the support plate 9. Several sets of fixing holes 113 are provided and pass through the support plate 9. The connecting groove 114 passes through the inner wall of one side of the adjustment groove 112. The fixing rod 115 is movably connected to the connecting groove 114 and is adapted to the size of the fixing hole 113.

[0031] It should be noted that by removing the fixing rod 115 from the fixing hole 113, the support plate 9 can be raised and lowered along the adjusting groove 112, and by inserting the fixing rod 115 into the fixing hole 113, the support plate 9 can be fixed at the current height.

[0032] like Figure 6 As shown, the adjustment assembly 11 also includes a third slide groove 116, a third slider 117, a third spring 118, and a pull block 119. The third slide groove 116 is formed on the inner wall of the connecting groove 114. The third slider 117 is fixedly connected to the outer periphery of the fixed rod 115 and slidably connected to the third slide groove 116. The third spring 118 is sleeved on the outer periphery of the fixed rod 115 and its two ends are respectively fixedly connected to the inner wall of the third slider 117 on the side away from the adjustment groove 112 and the side of the third slide groove 116 on the side away from the adjustment groove 112. The pull block 119 is fixedly connected to the outer end of the fixed rod 115.

[0033] It should be noted that pulling the pull block 119 outward will cause the third slider 117 to slide outward along the third slide groove 116 via the fixed rod 115 and compress the third spring 118. Releasing the pull block 119 will cause the third spring 118 to rebound, which will then cause the fixed rod 115 to move inward via the third slider 117.

[0034] In a specific application scenario, the first slider 710 first slides along the first groove 79 to compress the first spring 711. During this process, the rotating ring 77 drives the top block 78 to move synchronously with the first slider 710 within the cavity 74. When the top block 78 moves away from behind the mounting block 76, the second spring 714 rebounds and drives the mounting block 76 to move inward into the cavity 74 via the second slider 713. When the mounting block 76 is submerged in the through groove 75, the sampling cylinder 6 is placed at the bottom of the drive shaft 5 and the mounting hole 73 of the drive shaft 5 is closed. Aligning with mounting block 76, the first slider 710 is then released. The first spring 711 rebounds and, through the first slider 710, drives the rotating ring 77 and the top block 78 to move in opposite directions. When the top block 78 contacts mounting block 76, because the elastic force of the first spring 711 is greater than the sum of the elastic forces of multiple sets of second springs 714, the top block 78 will push mounting block 76 towards mounting groove 72 and, through the second slider 713, compress the second springs 714. When mounting block 76 is inserted into mounting hole 73, the drive shaft 5 is fixed in mounting groove. Within 72, the installation of sampling cylinder 6 is completed, and sampling can begin. During sampling, first, the device is moved to the desired sampling position using roller 8. Then, the pull block 119 is pulled outwards, causing it to slide outwards along the third slide groove 116 via the fixing rod 115, thus compressing the third spring 118. When the fixing rod 115 moves out of the fixing hole 113, the support plate 9 slides downwards along the adjusting groove 112 until the support 10 is tightly against the ground. Then, the pull block 119 is released, and the third... Spring 118 rebounds and drives the fixing rod 115 to move inward through the third slider 117. When the fixing rod 115 is inserted into the fixing hole 113 at the current height, the support plate 9 can be fixed at the current height. By adjusting the four sets of support plates 9 in this way, the device can be fixed in the current position and kept horizontal. Then, the hydraulic rod 3 and motor 4 are started to make the sampling cylinder 6 rotate downward and start sampling. After sampling is completed, the above operation is repeated in reverse to release the device and remove the sampling cylinder 6 for sample collection and cleaning.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
