Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Embodiment 1, by Figure 1-5The utility model relates to a water quality sampling device for sewage treatment, comprising a sampling tube 1, a hanger 2 is installed at the top end of the sampling tube 1, a sampling control component 3 is installed on the sampling tube 1, and an anti-blocking component 4 is installed at the bottom end of the sampling tube 1;

[0027] The sampling control assembly 3 includes a baffle 301 movably mounted inside the sampling tube 1. The bottom wall of the baffle 301 contacts the inner bottom wall of the sampling tube 1, and the outer wall of the baffle 301 contacts the inner wall of the sampling tube 1. The baffle 301 is evenly provided with first water inlet holes 302, and the bottom wall of the sampling tube 1 is provided with second water inlet holes 309 at the same angle. Stoppers 310 are evenly mounted on the inner bottom wall of the sampling tube 1. The diameter of the stoppers 310 is the same as that of the first water inlet holes 302. The inner diameter of the sampling tube 1 is the same, the block 310 is inserted into the first water inlet hole 302, the top of the sampling tube 1 is symmetrically installed with a top cylinder 304, the interior of the top cylinder 304 is movably installed with a movable block 305, the bottom end of the movable block 305 is fixedly installed with a vertical rod 303, the vertical rod 303 passes through the interior of the sampling tube 1, the bottom end of the vertical rod 303 is fixedly connected to the baffle 301, the top of the movable block 305 is fixedly installed with a first spring 306, the first spring 306 The top of the bottle 300 contacts the inner top wall of the top cylinder 304, and a magnetic block 307 is fixedly installed on the movable block 305. An electromagnet 308 is fixedly installed on the top of the top cylinder 304. The electromagnet 308 is electrically connected to a power supply and a sliding rheostat. The baffle 301 closes the second water inlet hole 309. At the same time, the baffle 310 is located in the first water inlet hole 302. When the sampling depth is not reached, water will not enter the sampling tube 1. During sampling, the baffle 301 moves upward, allowing water to enter the baffle 301 above the second water inlet hole 309 and the first water inlet hole 302, which is convenient for sampling. When the electromagnet 308 generates an attraction for the magnetic block 307, the baffle 301 moves upward, allowing water to enter the sampling tube 1. As the water pressure continues to increase, the baffle 301 moves downward until the second water inlet hole 309 is closed. The magnetic force of the electromagnet 308 is adjusted by the sliding rheostat, thereby facilitating the adjustment of the sampled water volume.

[0028] The anti-clogging component 4 includes a connecting ring 402 sleeved on the bottom end of the outer side of the sampling tube 1, a bottom retaining cage 403 is installed at the bottom end of the connecting ring 402, and a side plate 404 is symmetrically installed on the top of the connecting ring 402. A side tube 405 is fixedly installed on the side of the side plate 404 away from the sampling tube 1. A clamping rod 406 is movably installed inside the side tube 405. The end of the clamping rod 406 is clamped into the inside of the clamping groove 401. The clamping groove 401 is symmetrically opened on both sides of the sampling tube 1. A second spring is fixedly installed on the side of the clamping rod 406 away from the sampling tube 1. Spring 407, one end of the second spring 407 is fixedly connected to the inner wall of the end of the side tube 405 away from the sampling tube 1, and a pull rod 408 is fixedly installed on the side of the clamping rod 406 away from the sampling tube 1. The end of the pull rod 408 passes through the outside of the side tube 405, and the bottom retaining cage 403 is clamped and installed with the sampling tube 1. When the sampling tube 1 enters the sewage, the bottom retaining cage 403 can prevent large volumes of garbage from clogging the second water inlet 309. When the sampling is completed and the water needs to be drained, the connecting ring 402 is disassembled from the sampling tube 1 to facilitate sampling.

[0029] Working principle: During operation, first, the baffle 301 is in close contact with the inner bottom wall of the sampling tube 1 under the action of gravity, thereby closing the second water inlet hole 309 and sending the sampling tube 1 into the water through the lifting equipment. When the required sampling depth is reached, the electromagnet 308 is energized to generate attraction on the magnetic block 307, thereby pulling the baffle 301 to move upward, so that the first water inlet hole 302 leaves the block 310, allowing the sewage to enter the top of the baffle 301 through the second water inlet hole 309 and the first water inlet hole 302. When there is a lot of water above the baffle 301, the water pressure pushes the baffle 301 downward until the baffle 301 is in close contact with the inner bottom wall of the sampling tube 1, thereby stopping the water inflow. When it is necessary to control the water intake, the magnetic force of the electromagnet 308 is adjusted by the sliding rheostat, so that the baffle 301 moves downward under different water pressures, thereby controlling the sampling water volume.

[0030] When the sampling tube 1 moves downward, since the bottom end of the sampling tube 1 is provided with a bottom retaining cage 403, when the sampling tube 1 moves in the sewage, larger garbage, aquatic plants, etc. will not cause blockage to the second water inlet 309, ensuring smooth water inflow;

[0031] When draining water, pull the pull rod 408 outward to disengage the locking rod 406 from the locking slot 401, then remove the bottom retaining cage 403, and then control the electromagnet 308 to energize and move the baffle 301 upward, so that water is discharged from the second water inlet 309, completing the sampling.
