Description

Technical Field

[0001] This utility model relates to the field of atmospheric deposition collection technology, specifically an atmospheric deposition collector for investigating the causes of heavy metal pollution in arable land soil. Background Technology

[0002] When investigating the causes of heavy metal pollution in arable land soil, it is necessary to sample and test atmospheric deposition particles. Atmospheric deposition is an important source of heavy metal pollution in soil. Dust collection tanks can collect particulate matter in the atmosphere. By analyzing the heavy metal content in these particles, we can understand the contribution of atmospheric deposition to heavy metal pollution in soil. When using dust collection tanks, they are usually placed at a certain height above the ground to reduce ground interference. They are usually supported by brackets. However, since dust collection tanks are usually placed at a relatively high height, often between 5-12m above the ground, the brackets are usually fixed to improve stability. This results in long brackets that are inconvenient to store and store. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment of the invention, an atmospheric deposition collector for investigating the causes of heavy metal pollution in arable land soil includes multiple dust collection cylinders 200, comprising:

[0023] The system comprises a base plate 100, a support mechanism 300 for supporting multiple dust collection cylinders 200, and a bracket mechanism 400 for connecting to monitoring equipment to monitor the status of the multiple dust collection cylinders 200. The base plate 100 is located below the multiple dust collection cylinders 200. A rectangular groove is formed on the top surface of the base plate 100, and a connecting rod is fixedly connected between the two opposite inner sidewalls of the rectangular groove. A screw 110 is fixedly connected to the connecting rod. The support mechanism 300 is located between the base plate 100 and the multiple dust collection cylinders 200. At the location, the support mechanism 300 includes an internally threaded cylinder 310, which is screwed into the screw 110. A guide rope 320 is fixedly connected to the top of the internally threaded cylinder 310, and multiple slide cylinders 330 are slidably sleeved on the guide rope 320. One end of each slide cylinder 330 is fixedly connected to an insert, and each insert is movably inserted into the interior of an adjacent slide cylinder 330. The insert located at the bottom is fixedly connected to the top of the internally threaded cylinder 310. The bracket mechanism 400 is movably inserted into the clamping cylinder 340.

[0024] Specifically, by placing the base plate 100 on the ground, then screwing the internally threaded cylinder 310 into the screw 110, the internally threaded cylinder 310 is held in place against the base plate 100. Then, the guide rope 320 is straightened, and multiple sliding cylinders 330 are lowered down, so that two adjacent sliding cylinders 330 are interlocked through inserts to form a support rod. The guide rope 320 is then fixed to maintain the multiple sliding cylinders 330 in the support rod state. Thus, the taut guide rope 320 inside the multiple sliding cylinders 330 provides internal support for the interlocked sliding cylinders 330, thereby improving the stability of the multiple interlocked sliding cylinders 330. The guide rope 320 can be made of nylon rope, hemp rope, or polyester. A low-elasticity rope, such as a fiber rope, is used to support multiple dust-collecting cylinders 200 via a support mechanism 300. This allows the dust-collecting cylinders 200 to collect samples. When retrieving the dust-collecting cylinders 200, the internally threaded cylinder 310 can be unscrewed from the screw 110, and then the screw 110 can be rotated and retracted into the rectangular groove. The multiple interlocking slide cylinders 330 on the guide rope 320 can be disassembled and folded for storage, so that the multiple slide cylinders 330 are arranged side by side for easy storage by the user. The length of the slide cylinder 330 is fixed, and the number of slide cylinders 330 on the guide rope 320 can be set as needed. The base plate 100 can be used to stack heavy objects such as stones to increase the weight of the base plate 100. Example 1

[0025] like Figure 1-3 As shown, in this embodiment, the top of the uppermost slide cylinder 330 is movably sleeved with a retaining cylinder 340, and a threaded hole is provided on one side of the retaining cylinder 340. A bolt is screwed into the threaded hole, and one end of the bolt is rotatably connected to a stop block 341. Two insertion interfaces are provided at the top of the retaining cylinder 340.

[0026] In this embodiment, when multiple sliding cylinders 330 are interlocked to form a support rod, the clamping sleeve 340 is placed on the uppermost sliding cylinder 330, and then the guide rope 320 is tightened. Then, the bolt is manually turned so that the abutment block 341 presses against the guide rope 320, thereby facilitating the fixing of the guide rope 320. The surface of the abutment block 341 is provided with abrasive material to increase the friction with the guide rope 320 and prevent the guide rope 320 from slipping.

[0027] like Figure 3-4 As shown, in this embodiment, the support mechanism 400 includes:

[0028] The system comprises a U-shaped rod 410, a U-shaped plate 420, a support arm 430, and a connecting frame 440 for mounting monitoring equipment. The two arms of the U-shaped rod 410 are movably inserted into two insertion ports on the clamp 340. A connecting shaft is fixedly connected to the top of the U-shaped rod 410, and the U-shaped plate 420 is fixedly connected to the top of the connecting shaft. One end of the support arm 430 is rotatably connected between the two arms of the U-shaped plate 420, and the other end has an insertion hole. Two connecting collars are fixedly connected to one side of the connecting frame 440. A pin 441 is movably inserted into the insertion hole, and the pin 441 is movably inserted into the two collars. The outer wall of the pin 441, the inner walls of the two collars, and the inner wall of the insertion hole are all polygonal in cross-section. A rubber collar 210 can be detachably fitted onto the outer wall of any dust settling cylinder 200. A support ring 220 is movably fitted onto the outer wall of any dust settling cylinder 200. Each support ring 220 is located below the adjacent rubber collar 210. A support rod is provided on the outer wall of each support ring 220. A circular hole is opened at one end of each support rod. The inner wall of each circular hole is rotatably fitted with the connecting shaft. A thread is opened at the bottom of the outer wall of the connecting shaft, and a nut 201 is screwed into the bottom of the outer wall of the connecting shaft through the thread.

[0029] In specific implementation, the U-shaped rod 410 is fixed by inserting its two arms into two insertion interfaces. Then, multiple support rings 220 are rotated to distribute their ring bodies. Next, the nut 201 is turned to contact the support rods of the multiple support rings 220 and fix them together. Then, the dust-suppressing cylinder 200 is placed into the ring body of the support rings 220, so that the support rings 220 support the dust-suppressing cylinder 200 by supporting the rubber collar 210 on the dust-suppressing cylinder 200. When the position of the rubber collar 210 on the dust-suppressing cylinder 200 needs to be adjusted, the rubber collar 210 can be stretched to expand its inner diameter, and then the rubber collar 210 can be moved. The rubber collar 210 is then held fixed on the dust-suppressing cylinder 200 by its own elasticity. The monitoring equipment is fixed to the connecting frame 440 by the connector. After adjusting the angle of the connecting frame 440 by rotating it, the pin 441 is inserted into the two collars and the insertion hole to fix the relative position of the connecting frame 440 and the support arm 430. By rotating the support arm 430, the connecting frame 440 is moved away from the multiple dust collection cylinders 200, so that the monitoring equipment can monitor the internal situation of the multiple dust collection cylinders 200. When disassembling, the dust collection cylinders 200 can be taken out from the support rings 220, and the multiple support rings 220 can be rotated to stack the ring body. Then, the support arm 430 is rotated in the opposite direction to be close to the support rings 220. Then, the U-shaped rod 410 is taken out of the clamp 340, which makes it easy for users to disassemble and carry. Example 2

[0030] Based on Embodiment 1, the stability of the support arm 430 and the internal threaded cylinder 310 during use is improved by setting the support plate 421 and the connecting ring.

[0031] like Figure 2-3As shown, in this embodiment, a connecting ring is fixedly sleeved on the bottom of the outer side wall of the internally threaded cylinder 310, and an L-shaped support plate 421 is fixedly connected to one side of the U-shaped plate 420.

[0032] In practice, the contact surface between the internal threaded cylinder 310 and the base plate 100 can be increased by the connecting ring, thereby improving the stability of the internal threaded cylinder 310. Furthermore, the short arm of the support plate 421 supports the support arm 430, thereby improving the stability of the support arm 430 during use.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
