[0028] Example 1, such as Figures 1-4As shown, the wastewater quality monitoring and sampling device includes a sampler 1. The surface of the sampler 1 is equipped with a cleaning device 2 and a depth-fixing device 3. The surface of the sampler 1 has an inlet and a handle is fixedly connected to the surface of the sampler 1. When sampling wastewater, the sampler 1 is placed inside the wastewater. Under the action of the depth-fixing device 3, sampling is performed. After sampling, monitoring is carried out. After the test is completed, the wastewater is emptied and the inside of the sampler 1 is cleaned by the cleaning device 2 to avoid the generation of pollutants, thereby achieving the purpose of wastewater quality monitoring and sampling.
[0029] Reference Figure 2 The cleaning device 2 includes a magnetic ring 21 slidably connected to the surface of the sampler 1, and a cleaning ring 22 slidably connected to the inner wall of the sampler 1. The cleaning ring 22 is magnetically connected to the magnetic ring 21. A scraper 23 is fixedly connected to the top of the cleaning ring 22. Under the action of the scraper 23, the contaminants on the inner wall of the sampler 1 can be cleaned, thus achieving the cleaning function. When sampling sewage, the sampler 1 is placed inside the sewage, and sampling is performed under the action of the depth-fixing device 3. After sampling, monitoring is performed. After the test is completed, the sewage is emptied. The cleaning device 2 cleans the inside of the sampler 1, preventing the generation of contaminants, thus achieving the function of sewage quality monitoring and sampling. A brush 24 is fixedly connected to the bottom of the cleaning ring 22. The bristles of the brush 24 are in close contact with the inner wall of the sampler 1. Under the action of the brush 24, the dirt scraped off is removed. The contaminants can be cleaned by the brush 24. The inner wall of the magnetic ring 21 has a circular groove, and a ball bearing 26 is rotatably connected inside the groove. Under the action of the ball bearing 26, the magnetic ring 21 will not get stuck on the surface of the sampler 1. A baffle 25 is fixedly connected to the side of the sampler 1 and is located at the bottom of the sampler 1. Under the action of the baffle 25, the magnetic ring 21 will not slip off the surface of the sampler 1. After sampling, the wastewater is poured out, and the magnetic ring 21 is slid up and down, which drives the cleaning ring 22 to move. Then, under the action of the scraper 23 and the brush 24, the inner wall of the sampler 1 is scraped clean. Under the action of the ball bearing 26, the magnetic ring 21 will not get stuck on the surface of the sampler 1. Under the action of the baffle 25, the magnetic ring 21 will not slip off the surface of the sampler 1, thus achieving the cleaning effect.
[0030] Reference Figures 3-4The depth-fixing device 3 includes a pull rope 32 fixedly connected to the handle surface. A float 33 is mounted on one end of the pull rope 32. An adjusting frame 34 is fixedly connected to the surface of the float 33. The pull rope 32 is also fixedly connected to the surface of the adjusting frame 34. A sliding rod is slidably connected inside the sampler 1. A weight 31 is fixedly connected to one end of the sliding rod, and a stop block 38 is fixedly connected to the other end. Under the action of the weight 31, the sampler 1 can collect wastewater for monitoring after reaching a certain depth. The float 33 and pull rope 32 allow the sampler 1 to achieve a fixed depth. A retaining ring 37 is fixedly connected to the surface of the stop block 38. The retaining ring 37 fits tightly against the inlet, allowing the stop block 38 to be locked inside the inlet, preventing wastewater from flowing into the sampler 1 during sampling. A locking rod 35 is inserted into the side of the adjusting frame 34, with one end of the locking rod 35 inserted into the inner part of the adjusting frame 34. Under the action of the locking rod 35, the pull rope 32 can be fixed to the surface of the adjusting frame 34, thereby achieving the function of fixation. A spring 36 is sleeved on the surface of the locking rod 35. The pull of the spring 36 is fixedly connected to one end of the locking rod 35 and one end of the adjusting frame 34. Under the action of the spring 36, the locking rod 35 is inserted into the interior of the adjusting frame 34 in a self-locking state. When it is necessary to collect sewage at a certain depth, the pull rope 32 is adjusted to a suitable length under the action of the adjusting frame 34. Under the action of the spring 36, the locking rod 35 is inserted into the interior of the adjusting frame 34 in a self-locking state, thereby fixing the adjusting frame 34 and preventing the pull rope 32 from becoming longer. The sampler 1 is dropped into the sewage. When the sampler 1 sinks to a certain depth, under the action of the weight 31, the stop block 38 moves down and separates from the inlet, thereby allowing the sewage to enter the interior of the sampler 1, thereby achieving the function of fixed depth.
[0031] Working principle: When the wastewater quality monitoring sampling device is needed, the sampler 1 is placed inside the wastewater. Under the action of the depth-fixing device 3, sampling is performed. After sampling, monitoring is conducted. After testing, the wastewater is emptied, and the inside of the sampler 1 is cleaned by the cleaning device 2 to prevent the formation of pollutants, thus achieving the purpose of wastewater quality monitoring sampling. After sampling, all the wastewater is poured out, and the magnetic ring 21 slides up and down, thereby moving the cleaning ring 22. Under the action of the scraper 23 and the brush 24, the inner wall of the sampler 1 is scraped clean. Under the action of the ball bearing 26, the magnetic ring 21 will not re-emerge on the surface of the sampler 1. The phenomenon of the sampler getting stuck is prevented by the baffle 25, which prevents the magnetic ring 21 from slipping off the surface of the sampler 1, thus achieving the cleaning function. When it is necessary to collect sewage at a certain depth, the pull rope 32 is adjusted to a suitable length by the adjustment frame 34. Under the action of the spring 36, the locking rod 35 is inserted into the interior of the adjustment frame 34 in a self-locking state, thereby fixing the adjustment frame 34 and preventing the pull rope 32 from becoming too long. The sampler 1 is then dropped into the sewage. When the sampler 1 sinks to a certain depth, the baffle 38 moves down and separates from the inlet under the action of the weight 31, thus allowing the sewage to enter the interior of the sampler 1, thereby achieving the function of fixing the depth.
