Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a device for monitoring new pollutants in groundwater. Background Technology

[0002] New pollutants in groundwater refer to new harmful chemical substances, other than traditional pollutants, that are characterized by bioaccumulation, persistence, and high toxicity, which enter the groundwater environment through various pathways, leading to water quality deterioration, harm to the ecosystem, or human health.

[0003] Devices for monitoring new pollutants in groundwater are specialized equipment that use in-situ sensing, automatic sampling, and other technologies to accurately capture new pollutants such as novel organic pollutants in groundwater.

[0004] However, existing devices for monitoring new pollutants in groundwater have the following shortcomings: Traditional devices for monitoring new pollutants in groundwater are prone to damage when placed into or removed from monitoring wells via cables. This is due to the narrow space inside the well and the ease with which the cables can sway, causing the device to collide with the well wall. This can result in inaccurate monitoring data and even structural damage to the well wall. Utility Model Content

[0005] The main purpose of this invention is to provide a device for monitoring new pollutants in groundwater, which can effectively solve the problems that directly cause device damage, monitoring data deviation, and even well wall structure damage.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 - Appendix Figure 6 As shown, a device for monitoring new pollutants in groundwater includes a main body 1. Second through-columns 7 are respectively arranged on the upper and lower sides of the main body 1. A third through-column 8 is arranged on the outer side of each second through-column 7. A protective mechanism 3 is assembled on the outer side of two third through-columns 8. A fixing mechanism 4 is assembled inside the side end of one third through-column 8. The protective mechanism 3 includes multiple first blocks 31. A second block 32 is slidably connected inside each first block 31. A first guide post 34 is arranged inside each first block 31. A first spring 35 is arranged on the outer side of each first guide post 34. An arc-shaped plate 36 is arranged on the side of every two second blocks 32 away from the main body 1. Multiple rollers 37 are arranged on the side of each arc-shaped plate 36 away from the main body 1. A first through-column 38 is arranged on the outer side of the middle of each roller 37. A second limiting groove 39 is opened on both the front and rear sides of each first through-column 38. Each arc-shaped plate 36 has multiple second guide posts 310 slidably connected inside. Each second guide post 310 has a second spring 311 on its outer side. Each second guide post 310 has an arc-shaped block 312 on its side away from the main body 1. Each second block 32 has a first limiting groove 33 on its side end. Each second block 32 is slidably connected to the outer side of the first guide post 34 on its side near the first guide post 34. One side of each first spring 35 is fixedly connected to the side end of the second block 32, and the other side of each first spring 35 is fixedly connected to the inside of the first block 31. The side end of each first through post 38 is located at the side end of the arc-shaped block 312. A cable 2 is provided on the top of the main body 1. A float 5 is provided on the outer side of the upper part of the main body 1. Multiple L-shaped support rods 6 are arranged in a ring inside the float 5. The outer side below each L-shaped support rod 6 is slidably connected to the inside of the second through post 7.

[0018] The overall effect of Embodiment 1 is as follows: the relevant components can improve the protective performance of traditional devices for monitoring new pollutants in groundwater through mechanical transmission. The function of setting the first through column 38, the second limiting groove 39 and the arc block 312 is to enable the roller 37 to rotate while moving inside the arc plate 36. By setting multiple rollers 37 on the outside of the arc plate 36, the sliding friction between the body 1 and the well wall is converted into rolling friction, which greatly reduces the impact risk during diving or retrieval. This mechanical transmission method prevents direct damage to the device, deviation of monitoring data, and even damage to the well wall structure.

[0019] Example 2, as Figures 1-6 As shown, the fixing mechanism 4 includes multiple threaded rods 41, each threaded rod 41 has a column plate 42 on its outer side, a third through column 8 has multiple column grooves 43 inside, each L-shaped support rod 6 has multiple threaded grooves 44 on its side near the threaded rod 41, and the outer side of each threaded rod 41 is threaded through the inner side of the second through column 7 and connected to the inner side of the L-shaped support rod 6. The diameter of each column groove 43 is larger than the diameter of the column plate 42.

[0020] The overall effect of embodiment 2 is as follows: by setting the fixing mechanism 4, the threaded rod 41 moves threadedly inside the third through post 8 and the second through post 7, fixing the L-shaped support rod 6 moving inside the second through post 7 at different positions, which makes it convenient for the operator to adjust the depth of the body 1. By setting the diameter of the column groove 43 to be larger than the diameter of the column plate 42, friction is prevented between the column plate 42 and the inside of the third through post 8. At the same time, the threaded rod 41 is limited to fall out of the inside of the third through post 8, which makes it convenient for the operator to rotate the threaded rod 41 at any time.

[0021] The float 5 is fitted onto the upper outer side of the main body 1, allowing the L-shaped support rod 6 to slide into the second through column 7. The threaded rod 41 is rotated so that it passes through the second through column 7 and is threaded into the threaded groove 44 of the L-shaped support rod 6. When the threaded rod 41 rotates, the column plate 42 moves towards the main body 1 inside the column groove 43, fixing the cable 2 to the top of the main body 1. The cable length is marked to indicate the cable release length corresponding to different diving depths. The operator controls the diving depth of the device by releasing or retrieving the cable 2, allowing the main body 1 to gradually sink to the target depth in the groundwater monitoring well. During the diving process, the roller 37 on the outer side of the arc plate 36 first contacts the inner wall of the monitoring well. The roller 37 rotates on the arc block 312 through the first through column 38, converting the sliding friction between the device and the well wall into rolling friction. When there are protrusions on the well wall or the cable is lightly... Slight shaking causes the device to deviate, and the well wall exerts lateral pressure on the roller 37. On one hand, it pushes the arc block 312 to compress the second spring 311, and the second guide post 310 slides in the arc plate 36. The lateral pressure is transmitted to the second block 32, causing the second block 32 to slide along the outside of the first guide post 34 and compress the first spring 35. The rebound force of the first spring 35 drives the second block 32 to reset, pushing the arc plate 36 to reset, avoiding hard contact between the device and the well wall. After reaching the designated depth, the monitoring components inside the main body 1 can accurately collect groundwater samples and analyze the concentration of new pollutants. After the monitoring is completed, the device is slowly retrieved through the cable 2. During the lifting process, the protective mechanism 3 repeats the buffering and guiding action of the diving stage. The roller 37 rolls to reduce the lifting resistance, and the first spring 35 and the second spring 311 buffer the possible lateral impact force.
