Description

Technical Field

[0001] The present invention relates to the technical field of river pollution detection, and in particular to a river pollution source tracing detection device. Background Art

[0002] River pollution refers to the direct discharge of untreated wastewater containing harmful substances from industry, life, agriculture, etc. into rivers. The discharge exceeds the river's own purification capacity, which will affect the river water and the river's environmental quality. In river pollution control, it is usually necessary to use a water sampler to sample the water in the river, and then judge the degree of pollution of the water in the river by analyzing the water samples.

[0003] After searching, it is found that the existing monitoring devices first place the sampler to the target location and then perform suction to extract the water sample. What's more, some devices can even extract polluted water at different levels. However, this detection method will undoubtedly destroy the original state and turbidity of the water due to the extraction process. Therefore, we propose a new detection equipment that can not destroy the physical state of the target water body to improve the accuracy of the detection. Summary of the invention

[0016] 1.

[0017] 2. Through the water guide plate, when there is a relatively obvious water flow speed in the test water area, the water guide plate can automatically adjust the posture of the device, and can quickly adjust the vertical surface between the two legs to be parallel to the direction of water flow, thereby reducing resistance while not muddying the water in the test area.

[0018] 3. By setting the pull ring and the rope slip ring, not only can the rope slip ring be kept in the middle position of the pull ring when lifting at a close distance, but also when pulling to the shore at a long distance, the rope slip ring will slide close to one of the side blocks, thereby preventing the device from being pulled over during pulling.

[0019] 4. Through the rack slide bar and the reset spring at its top, when it is necessary to change the direction of the water spray or offset the forward flow of the water, it is only necessary to control the reduction motor to start. At this time, the intermittent gear can slowly push the piston plate down, and then the pumped water will be sprayed backward at the required speed to generate propulsion power, avoiding the propeller-type propulsion that easily generates bubbles and then causes changes in the water quality in the detection area, affecting the actual detection results.
