Description

Technical Field

[0001] The utility model belongs to the technical field of groundwater monitoring, and particularly relates to a monitoring device for groundwater pollution monitoring. Background Technique

[0002] Groundwater pollution is a serious environmental problem, which mainly refers to the phenomenon that human activities cause changes in the chemical composition, physical properties and biological characteristics of groundwater, and then lead to the decline of groundwater quality. The following is a detailed analysis of groundwater pollution: Definition: Groundwater pollution refers to the phenomenon that the content of harmful substances in groundwater increases due to human activities or natural processes, exceeding the self-purification capacity of the water body, thus causing water quality deterioration. Characteristics: Groundwater pollution has the characteristics of slow process, difficult to detect and difficult to treat. Due to the extremely slow flow of groundwater, the migration and diffusion of pollutants in the aquifer are also very slow, so the pollution often occurs gradually and is not easy to be detected. In addition, once groundwater pollution is formed, even if the pollution source is completely eliminated, it takes a long time for the water quality to recover.

[0003] At present, there are prominent problems in the groundwater monitoring well network within the factory boundaries of most petrochemical industry polluting enterprises, such as low density, lack of monitoring data at the factory boundary, insufficient monitoring frequency to support the groundwater environmental risk control within the factory boundary, and poor timeliness of groundwater monitoring. Existing products cannot achieve online intelligent detection and control of groundwater. Our product adds online monitoring of multiple characteristic pollutants in the petrochemical industry according to the national groundwater quality standard.

[0004] When deploying array sensors at designated positions, the main pipeline and branch pipeline methods are often used. To ensure that the monitored area meets the requirements, sensors are often required to be deployed on both the main pipeline and the branch pipeline. The existing sensor deployment method using only cables, reinforcement structures and sensors often cannot accurately deliver the sensors to the branch pipeline. If the sensors do not reach the accurate positions, it will directly lead to a decrease in monitoring accuracy, an unclear coverage range, and it is difficult to recover such sensors for maintenance and replacement, resulting in poor usability.

The storage wheel and the guide wheel are both rotatably embedded in the inner wall of the protective shell through a rotating shaft. The sensor body is embedded in the axial opening of the impact head. The cable is wound on the inner wall of the storage wheel. One end of the cable is signal-connected to the sensor body, and the other end of the cable is signal-connected to an external control center through Ethernet. The cable matches the guide wheel, and the sealing plug is threadedly connected to the top of the inner wall of the housing.

[0009] Furthermore, a lubricating ring is sleeved on the outer wall of the housing.

[0027] The release component is arranged on the inner wall of the housing 1, where: the release component includes an impact head 2, a protective shell 3, a storage wheel 4, a guide wheel 5, a sensor body 6, a cable 7, a sealing plug 101 and a guide hole 103. The guide hole 103 is opened on the outer wall at the bottom end of the housing 1. The impact head 2 is slidably embedded in the inner wall of the guide hole 103. Both the storage wheel 4 and the guide wheel 5 are rotatably embedded in the inner wall of the protective shell 3 through a rotating shaft. The sensor body 6 is embedded in the axial opening of the impact head 2. The cable 7 is wound around the inner wall of the storage wheel 4. One end of the cable 7 is signal-connected to the sensor body 6, and the other end of the cable 7 is signal-connected to an external control center through Ethernet. The cable 7 matches the guide wheel 5. The sealing plug 101 is threadedly connected to the top of the inner wall of the housing 1.

[0028] In a specific embodiment of the present invention, through the release component, the sensor can be quickly deployed to a specified position, and during groundwater exploration, continuous deployment of the sensor body 6 can be carried out between the main pipeline and the straight pipeline, avoiding the problem of poor detection accuracy caused by the failure to achieve array deployment of sensors during the process of monitoring groundwater pollution. Moreover, during the deployment process of the sensor, it has good operational convenience. First, install the sealing plug 101 on the outer wall of one end of the drilling rod, lower the housing 1 along the main pipeline. When at the branch pipeline, use the sealing plug 101 to convey high-pressure water flow to ensure that the guide hole 103 and the branch pipeline are on the same axis. Subsequently, use the high-pressure water flow to impact the impact head 2, so that the impact head 2 drives the sensor body 6 and the cable 7 to leave the housing 1. When the cable 7 is pulled, the cable 7 is guided by the guide wheel 5, and then the storage wheel 4 releases the cable 7 to ensure the stable movement of the impact head 2. When it is necessary to recover the specified sensor body 6 and the impact head 2 for maintenance or replacement, start the recovery motor 8. Through the rotation of the storage wheel 4, the cable 7 is retracted, and the impact head 2 slides to the inside of the guide hole 103.

[0029] Specifically, a lubricating ring 102 is sleeved on the outer wall of the housing 1.

[0030] In a specific embodiment of the present invention, the lubricating ring 102 can ensure the stable sliding of the housing 1.

[0031] Specifically, the sealing plug 101 matches the drilling rod, and the sealing plug 101 is used to supply high-pressure water.

[0032] In a specific embodiment of the present invention, the inner opening of the sealing plug 101 is used to supply high-pressure water.

[0033] Specifically, a sealing shell 301 is fixedly arranged on the outer wall of the protective shell 3, and a recovery motor 8 is embedded in the inner wall of the sealing shell 301.

[0034] In a specific embodiment of the present invention, the recovery motor 8 is used to drive the storage wheel 4 to rotate.

[0035] Specifically, the output end of the recovery motor 8 is fixedly arranged at the center of one side of the outer wall of the storage wheel 4.

[0036] In a specific embodiment of the present utility model, the output end of the recovery motor 8 is fixedly arranged at the center of one side of the outer wall of the storage wheel 4, which can ensure the stable recovery of the cable 7.

[0037] Specifically, the opening on one side of the outer wall of the protective shell 3 matches the cable 7.

[0038] In a specific embodiment of the present utility model, the opening on one side of the outer wall of the protective shell 3 matches the cable 7, which can prevent the cable 7 from getting stuck.

[0039] Working principle:

[0040] Through the release component, the sensor can be quickly deployed to the specified position, and during groundwater exploration, continuous deployment of the sensor main body 6 can be carried out between the main pipeline and the straight pipeline, avoiding the problem of poor detection accuracy caused by the lack of array deployment of the sensor during the monitoring of groundwater pollution. And during the deployment process of the sensor, it has good operation convenience. First, install the sealing plug 101 on the outer wall of one end of the drilling rod, lower the outer shell 1 along the main pipeline. When at the branch pipeline, use the sealing plug 101 to convey high-pressure water flow to ensure that the guiding hole 103 and the branch pipeline are on the same axis. Then use the high-pressure water flow to impact the impact head 2, so that the impact head 2 drives the sensor main body 6 and the cable 7 to leave the outer shell 1. When the cable 7 is pulled, the cable 7 is guided by the guiding wheel 5, and then the storage wheel 4 releases the cable 7 to ensure the stable movement of the impact head 2. When it is necessary to recover the specified sensor main body 6 and the impact head 2 for maintenance or replacement, start the recovery motor 8, and through the rotation of the storage wheel 4, take up the cable 7, and the impact head 2 slides to the inside of the guiding hole 103.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
