Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling, in particular to a water quality sampling device for deep water quality detection. Background Art

[0002] With the development of social economy, human beings are increasingly destroying the natural environment, and various resources in nature have also been greatly damaged and polluted. In particular, water resources are an important resource for human life activities. The quality of water is related to human life and health, so ecological environmental protection actions targeting water resources are imminent; in nature, most of the freshwater resources on land exist underground, and people usually obtain groundwater resources by digging wells. However, due to the complex underground environment, some water resources are often polluted by underground minerals or human activities, so it is necessary to sample and test the groundwater quality.

[0003] At present, a Chinese utility model with publication number CN220270912U discloses a water quality sampling device for ecological environment protection, which relates to the field of water quality sampling technology, including a mobile base, a lifting structure fixedly installed on the top of the mobile base, a driving structure fixedly installed on the movable end of the lifting structure, and a sampling component movably connected to the movable end of the driving structure. The water quality sampling device for ecological environment protection, by setting a lifting structure and a driving structure, uses an electric push rod inside the side frame to drive the mounting plate to drive the sampling component to adjust the height through the lifting frame, and then cooperates with the driving frame to drive the sampling component to adjust the position through the electric cylinder structure, so that when the sampling device is collecting in deep water, the sampling component can be easily extended underwater, ensuring the stable progress of water quality sampling work, and at the same time effectively sampling water quality far away from the water bank, which facilitates the work of the water quality sampling device.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that the above equipment, when used, can solve the problem that the existing environmental detection samplers mostly sample a single water layer at a time when taking water quality samples. If you want to take water quality samples at other depths, you need to empty the water source inside the device, and extract and lower the water sampler again, so that the entire sampling process requires multiple samplings, which is cumbersome to operate, causing the staff to spend a long time, inconvenient for the staff to use, and low work efficiency. However, during use, the device is not equipped with a cleaning structure. When sampling deep water through the sampling barrel, impurities and weeds in the deep water will be adsorbed to the surface of the barrier net, causing the weeds to block the barrier net, thereby reducing the sampling efficiency of the sampling barrel.

After the scraper 10 is installed, the connecting rope 4 is released through the winding frame 3 to make the sampling tube 5 fall into the deep water, and then the waterproof motor 121 is started to drive the worm 122 to rotate. Then the worm 122 drives the worm wheel 123 to rotate, and then the worm wheel 123 can drive the rotating rod 8 to rotate the mounting plate 9, and then drive the scraper 10 to rotate, so that the scraper 10 can cut the weeds at the bottom of the barrier net 6, and at the same time can scrape the bottom of the barrier net 6 to prevent the weeds from being adsorbed to the surface of the barrier net 6 and affecting the water intake effect of the sampling tube 5, thereby achieving the effect of easy cleaning, and the scraper 10 will drive the connecting plate 16 to make the brush 17 rotate with it, and the surface of the barrier net 6 can be cleaned by the brush 17, thereby improving the cleaning effect of the surface of the barrier net 6.

[0038] To sum up: this kind of water quality sampling device for deep water quality testing, by setting a rotating rod 8, a mounting plate 9, a scraper 10 and a driving assembly 12, can effectively enable the driving assembly 12 to drive the rotating rod 8 to rotate the mounting plate 9, and drive the scraper 10 through the mounting plate 9 to cut the bottom of the barrier net 6, and at the same time, the bottom of the barrier net 6 can be scraped, which solves the problem that the device has no cleaning structure. When sampling deep water through the sampling barrel, impurities and weeds in the deep water will be adsorbed to the surface of the barrier net, causing the weeds to block the barrier net, thereby reducing the sampling efficiency of the sampling barrel.
