Description

Technical Field

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

[0002] In environmental monitoring, on-site soil sampling is a crucial step in obtaining analytical samples, and it typically requires specialized sampling equipment. To facilitate rapid movement between different monitoring points in the field, existing sampling devices are usually equipped with wheels on their bases to improve portability and deployment efficiency.

[0003] However, while this wheeled mobility method offers ease of movement, it also introduces inherent structural flaws to actual sampling operations. Field environments often present complex terrain conditions, including unevenness, softness, or incline. When a wheeled sampling device is stationary on such ground and ready to drill for sampling, the wheeled structure itself cannot provide an absolutely stable working platform.

[0004] During drilling operations, the resulting vibrations and downforce are transmitted through the wheels to uneven ground, causing the entire device to sway or shift slightly. This instability not only affects the verticality of the drill rod and reduces sampling accuracy, but may even lead to sampling failure. More seriously, on some extremely uneven terrains, the vibrations during operation may cause the equipment to overturn, posing a safety hazard. This creates an irreconcilable contradiction between the ease of movement of the equipment and operational stability. To address these issues, an adjustable sampling device for environmental monitoring is proposed. Summary of the Invention

[0005] In view of the problems in the existing technology of adjustable sampling devices for environmental monitoring, which use a wheel structure and are prone to instability and shaking when operating on uneven ground in the field, thus affecting the drilling and sampling accuracy and safety, this utility model aims to provide an adjustable sampling device for environmental monitoring with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an adjustable sampling device for environmental monitoring, comprising: a base, wheels rotatably connected to the bottom of the base, a mounting plate fixedly connected to the base, and a drilling mechanism fixedly connected to the mounting plate; and at least one adjustment mechanism fixedly connected to the base.

[0007] The adjustment mechanism includes a lower sleeve and an upper sleeve that is slidably sleeved outside the lower sleeve. The adjustment mechanism also includes a second fixed column, a third fixed column, a rotating pedal, and an elbow lever.

[0008] Furthermore, the second and third fixed posts are fixed to the base; the rotating pedal is rotatably connected between the second and third fixed posts; one end of the elbow is rotatably connected to the rotating pedal, and the other end of the elbow is rotatably connected to the upper sleeve.

[0009] Preferably, the adjusting mechanism further includes a first fixed post and a spring; the first fixed post is fixed to the upper sleeve; the two ends of the spring are respectively connected to the first fixed post and the third fixed post.

[0010] Preferably, the device further includes a waterproof mechanism fixedly connected to the mounting plate; the waterproof mechanism includes a rainproof canopy, a first motor, a lead screw, and a telescopic linkage mechanism consisting of multiple connecting rods hinged together; the output shaft of the first motor is connected to the lead screw for transmission, and the lead screw drives the telescopic linkage mechanism to unfold or retract to drive the rainproof canopy to unfold or retract.

[0011] Preferably, the waterproof mechanism further includes a fixed plate and an adjusting block that is threadedly engaged with the lead screw; the lead screw is rotatably mounted in the fixed plate; and the adjusting block is connected to the telescopic linkage mechanism.

[0012] Preferably, the waterproofing mechanism further includes a receiving plate, a fixed rod fixed to the receiving plate, and a sliding plate slidably connected to the fixed rod; the sliding plate is connected to the telescopic linkage mechanism.

[0013] Preferably, the waterproofing mechanism further includes a connecting rod that connects the sliding plate and the rainproof canopy.

[0014] Preferably, the drilling mechanism includes a mounting frame, a second motor fixed on the mounting frame, a drill rod driven by the second motor, and sampling blades fixed to the drill rod.

[0015] Preferably, the device further includes a handrail fixedly connected to the base.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting an adjustment mechanism, includes a rotating pedal, an elbow lever, and a retractable sleeve. By stepping on the rotating pedal, the elbow lever can be driven to extend the sleeve and lift the base of the entire device off the ground. This solves the problem of platform shaking and poor stability caused by the wheels contacting the ground when the environmental monitoring sampling device is operating on uneven ground in the field. It achieves the technical effect of firmly fixing the equipment at the work site, ensuring the verticality and accuracy of the drilling and sampling process, and improving the sampling quality and operational safety.

[0017] 2. This utility model, by setting up a waterproof mechanism, which includes a motor, a lead screw, and a connecting rod telescopic mechanism, can automatically unfold or retract the rainproof tarpaulin to cover the equipment by driving the lead screw with the motor. This solves the problem in the prior art that field environmental monitoring sampling devices lack protection against severe weather, cannot work normally in rainy or snowy weather, and cause work interruption and low efficiency. It achieves the technical effect of enabling the equipment to operate normally in rainy or snowy weather, improving the environmental adaptability and all-weather operation capability of the device, and ensuring the continuity of monitoring work.

[0018] 3. This utility model integrates the drilling mechanism, the adjustment mechanism for fixing, the waterproof mechanism for protection, and the wheels and handrails for movement onto the same base, solving the problems of existing technologies where field sampling usually requires carrying multiple separation devices, is cumbersome to operate, and has poor coordination. It achieves the effect of high functional integration, compact structure, and convenient operation. A single person can complete the entire process of moving, fixing, sampling, and protecting the equipment, which greatly improves work efficiency. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

[0022] Please refer to Figures 1 to 7 This utility model provides an adjustable sampling device for environmental monitoring, which aims to solve the problems in the prior art where the equipment is unstable due to uneven ground during field operations, and lacks protective structures against rain and snow, thus limiting its applicability.

Reference Figure 4 , Figure 5 and Figure 6The adjustment mechanism 5 includes a lower sleeve 507 and an upper sleeve 501 that is slidably sleeved outside the lower sleeve 507. The adjustment mechanism 5 also includes a second fixed post 504, a third fixed post 506, a rotating pedal 505, and an elbow 502. The second fixed post 504 and the third fixed post 506 are fixed to the base 1. The rotating pedal 505 is rotatably connected between the second fixed post 504 and the third fixed post 506. One end of the elbow 502 is rotatably connected to the rotating pedal 505, and the other end of the elbow 502 is rotatably connected to the upper sleeve 501. The adjustment mechanism 5 also includes a first fixed post 503 and a spring 508. The first fixed post 503 is fixed to the upper sleeve 501, and the two ends of the spring 508 are respectively connected to the first fixed post 503 and the third fixed post 506. Reference Figure 2 and Figure 3 The waterproof mechanism 3 includes a rainproof canopy 4, a first motor 309, a lead screw 302, and a telescopic linkage mechanism consisting of multiple connecting rods 305 hinged together. The output shaft of the first motor 309 is connected to the lead screw 302. The lead screw 302 drives the telescopic linkage mechanism to unfold or retract, thereby causing the rainproof canopy 4 to unfold or retract. The waterproof mechanism 3 also includes a fixed plate 301 and an adjusting block 303 threadedly engaged with the lead screw 302. The lead screw 302 is rotatably installed in the fixed plate 301. The adjusting block 303 is connected to the telescopic linkage mechanism. The waterproof mechanism 3 also includes a receiving plate 306, a fixed rod 307 fixed on the receiving plate 306, and a sliding plate 304 slidably connected to the fixed rod 307. The sliding plate 304 is connected to the telescopic linkage mechanism. The waterproof mechanism 3 also includes a connecting rod 308, which connects the sliding plate 304 and the rainproof canopy 4. Reference Figure 7 The drilling mechanism 6 includes a mounting frame 601, a second motor 604 fixed on the mounting frame 601, a drill rod 602 that is connected to the second motor 604, and a sampling blade 603 fixed on the drill rod 602.

[0024] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the adjustable sampling device for environmental monitoring also includes an adjustment mechanism 5 and a waterproof mechanism 3, and specific structural cooperation and connection relationships are formed between the adjustment mechanism 5 and the base 1, and between the waterproof mechanism 3 and the mounting plate 2.

[0025] Please refer to the following carefully. Figures 4 to 6 The core structure of the adjustment mechanism 5 will be described in detail below: The adjustment mechanism 5 includes a lower sleeve 507 and an upper sleeve 501 that is slidably sleeved outside the lower sleeve 507. The adjustment mechanism 5 also includes a second fixed post 504 and a third fixed post 506, both of which are fixed to the base 1. A rotating pedal 505 is rotatably connected between the second fixed post 504 and the third fixed post 506. The adjustment mechanism 5 also includes an elbow 502, one end of which is rotatably connected to the rotating pedal 505, and the other end of which is rotatably connected to the upper sleeve 501.

[0026] In the assembled state, the rotating pedal 505, the elbow 502, the upper sleeve 501, and the base 1 together form an elbow-type linkage mechanism. By pressing down the rotating pedal 505, it rotates around the second fixed column 504 and the third fixed column 506. This rotation drives the elbow 502 to move, and in turn pushes the upper sleeve 501 to slide out relative to the lower sleeve 507. This elbow-type transmission structure ensures that a large locking force can be generated at the end of the stroke, so that the lower sleeve 507 can be stably supported on the ground, thereby lifting the entire base 1.

[0027] Please refer to Figure 2 and Figure 3 The core structure of waterproof mechanism 3 will be described in detail below: The waterproof mechanism 3 includes a first motor 309, a lead screw 302, an adjusting block 303 threadedly engaged with the lead screw 302, a telescopic linkage mechanism consisting of multiple connecting rods 305 hinged together, and a rainproof canopy 4. The output shaft of the first motor 309 is connected to the lead screw 302 for transmission. The adjusting block 303 is connected to one end of the telescopic linkage mechanism, and the other end of the telescopic linkage mechanism is connected to the rainproof canopy 4 through a sliding plate 304. This structure converts the rotational motion of the first motor 309 into the unfolding or retracting motion of the telescopic linkage mechanism through the lead screw 302, thereby realizing the automatic opening and closing of the rainproof canopy 4.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to achieve automatic reset of the adjustment mechanism 5, please refer to... Figure 4 and Figure 5 The adjustment mechanism 5 also includes a first fixed post 503 and a spring 508. The first fixed post 503 is fixed to the upper sleeve 501, and the two ends of the spring 508 are respectively connected to the first fixed post 503 and the third fixed post 506. The spring 508 is stretched to store elastic energy when the adjustment mechanism 5 is extended.

[0029] As another preferred embodiment, for achieving automated protection of the device, please refer to... Figure 1 and Figure 2The device also includes a waterproof mechanism 3 fixedly connected to the mounting plate 2. The waterproof mechanism 3 includes a rainproof canopy 4, a first motor 309, a lead screw 302, and a telescopic linkage mechanism consisting of multiple connecting rods 305 hinged together. The output shaft of the first motor 309 is connected to the lead screw 302 for transmission. The lead screw 302 is used to drive the telescopic linkage mechanism to unfold or retract, thereby driving the rainproof canopy 4 to unfold or retract.

[0030] As a specific implementation of waterproof mechanism 3, please refer to Figure 3 The waterproof mechanism 3 also includes a fixed plate 301 and an adjusting block 303 that is threadedly engaged with the lead screw 302. The lead screw 302 is rotatably installed in the fixed plate 301, and the adjusting block 303 is connected to the telescopic linkage mechanism, thereby accurately converting the rotational motion of the lead screw 302 into the linear telescopic motion of the telescopic linkage mechanism.

[0031] As a further limitation on waterproof mechanism 3, please refer to Figure 3 The waterproof mechanism 3 also includes a receiving plate 306, a fixing rod 307 fixed on the receiving plate 306, and a sliding plate 304 slidably connected to the fixing rod 307. The sliding plate 304 is connected to the moving end of the telescopic linkage mechanism. The waterproof mechanism 3 also includes a connecting rod 308, which is connected between the sliding plate 304 and the rainproof canopy 4, providing guidance and support for the unfolding of the rainproof canopy 4.

[0032] As a preferred implementation method, to achieve the soil sampling function, please refer to... Figure 7 The drilling mechanism 6 includes a mounting frame 601, a second motor 604 fixed on the mounting frame 601, a drill rod 602 that is connected to the second motor 604, and a sampling blade 603 fixed on the drill rod 602.

[0033] In a preferred embodiment, to facilitate the movement of the device, the device also includes a handrail 8 fixedly connected to the base 1.

[0034] The working principle of the adjustable sampling device for environmental monitoring of this invention is as follows: When field soil sampling is required, the operator first pushes the base 1 with the handle 8, so that the wheels 7 roll on the ground and move the entire device to the designated sampling location. Upon arrival at the designated location, the operator steps on and presses down the rotating pedal 505 of the adjustment mechanism 5. The rotating pedal 505 rotates around the second fixed post 504 and the third fixed post 506. This rotation causes the upper sleeve 501 to slide upward relative to the lower sleeve 507 via the elbow 502. During this process, the spring 508 connecting the first fixed post 503 and the third fixed post 506 is stretched. When the bottom of the lower sleeve 507 contacts the ground and reaches a stable locking position, the height of the adjustment mechanism 5 will be higher than the wheel 7, thereby lifting the base 1 and the wheel 7 off the ground together. In this way, the problem of device instability caused by uneven ground is solved, providing a stable working platform for subsequent sampling. When soil sampling is required, the second motor 604 on the drilling mechanism 6 is started. The second motor 604 drives the drill rod 602 to rotate at high speed through the transmission mechanism. The sampling blade 603 fixed on the drill rod 602 rotates synchronously and drills into the soil, bringing the soil sample out of the ground along the spiral structure of the drill rod 602. When encountering rain or snow during operation, the first motor 309 of the waterproof mechanism 3 is activated. The first motor 309 drives the lead screw 302 to rotate inside the fixed plate 301. The adjusting block 303, which is threadedly engaged with the lead screw 302, moves along the axial direction of the lead screw 302. The movement of the adjusting block 303 pushes the telescopic linkage mechanism composed of multiple connecting rods 305 to unfold. The unfolding of the telescopic linkage mechanism pushes the sliding plate 304 to slide along the fixed rod 307 fixed on the receiving plate 306. The connecting rod 308 connected to the sliding plate 304 moves accordingly, and finally the rainproof canopy 4 is unfolded smoothly to cover and protect the drilling mechanism 6 and other equipment below.
