[0017] 1. This depth-adjustable water microorganism detection equipment for aquaculture is used by researchers to obtain water samples at different water levels during the process of sampling water bodies. First, the extension rod is stretched to the required position, and the sling rope can be released from the reel through the eccentric handle. The length of the sling rope can then be adjusted according to the water level data of different areas inside the river. The researchers can use the weight of the sampling rack on the sling rope to throw one end of the sling rope so that the sampling rack falls into the water at a certain depth, and then start the servo motor, which drives the rotating rod to rotate. , the lifting cross plate can be made to perform reciprocating lifting and lowering motion through the reciprocating thread groove, and the lifting cross plate drives the water suction rod to perform lifting and lowering motion.

The depth-adjustable water microorganism detection equipment for aquaculture, when the water suction rod rises and then descends, the water suction rod drives the limiting plate 1 to descend, so that the limiting plate 1 pushes the piston to descend and exposes the water suction port. The limiting plate 2 blocks the water inlet on the water suction cylinder through the spring and the blocking ball, so that the water in the water suction cylinder is discharged into the water suction rod through the water suction port, and the water to be tested is transported to the sampling test tube through the water suction pipe. The excess gas in the sampling test tube is discharged through the exhaust valve. After the sampling is completed, the sampling test tube is taken out and tested, so that the user can quickly take out the water sample and quickly sample the water sample at the next position, thereby improving the efficiency of water sample collection.

Because the gear is engaged with the annular gear plate, when the cleaning rod drives the gear to move, the gear can drive the cleaning rod to rotate.

A water suction port 307 is provided on the outer wall of the water suction rod 306, and a limiting plate 308 is fixedly connected to the outer wall of the water suction rod 306.

The piston 310 is located between the limiting plate 1 308 and the limiting plate 2 309. The outer wall of the piston 310 is slidably connected to the inner wall of the water suction cylinder 305. This arrangement is because the friction between the piston 310 and the inner wall of the water suction cylinder 305 is greater than the friction between the piston 310 and the water suction rod 306.

[0037] The bottom of the second limiting plate 309 is fixedly connected to a spring 311 , and one end of the spring 311 away from the second limiting plate 309 is fixedly connected to a blocking ball 312 . This arrangement is to enable the blocking ball 312 to block the water suction end of the water suction cylinder 305 .

[0038] The inner wall of the water suction rod 306 is fixedly connected to a water suction pipe 31, the outer wall of the water suction pipe 31 is provided with an exhaust valve 32, the outer wall of the water suction pipe 31 is fixedly connected to a connecting bottle cap 33, the top of the connecting bottle cap 33 is fixedly connected to the bottom of the sampling rack 201, and the inner wall of the connecting bottle cap 33 is threadedly connected to a sampling test tube 34.

[0039] The bottom end of the rotating rod 302 is fixedly connected to the rotating rod 401, and the rotating rod 401 passes through the top of the filter cartridge 203 and extends to the outside. The end of the rotating rod 401 away from the rotating rod 302 is fixedly connected to the connecting seat 402.

This arrangement is to allow the rotating rod 302 to drive the rotating rod 401 to rotate, and the rotating rod 401 drives the connecting seat 402 and the cleaning rod 403 to rotate. Because the gear 405 is engaged with the annular gear plate 406, when the cleaning rod 403 drives the gear 405 to move, the gear 405 can drive the cleaning rod 403 to rotate, and the cleaning rod 403 drives the brush 404 to clean the filter slot 407, reducing the accumulation of floating objects in the filter slot 407, which can improve the quality of the water sample and facilitate subsequent detection.

[0040] In summary, the working principle of the depth-adjustable water microorganism detection equipment for aquaculture in the embodiment of the present invention is as follows: when scientific researchers need to take samples of water, if they need to obtain water samples at different water levels, they first stretch the extension rod 101 to the required position, and can release the hanging rope 104 from the take-up reel 103 through the eccentric handle 102, and then can adjust the release length of the hanging rope 104 according to the water level data of different areas inside the river, and the scientific researchers can throw one end of the hanging rope 104 through the weight of the sampling rack 201 on the hanging rope 104, so that the sampling rack 201 falls into a position at a certain depth in the water, and then start the servo motor 301, which drives the rotating rod 302 to rotate. The lifting cross plate 304 is made to perform a reciprocating lifting motion through the reciprocating thread groove 303, and the lifting cross plate 304 drives the water suction rod 306 to perform a lifting motion. When the water suction rod 306 rises, the friction force between the piston 310 and the inner wall of the water suction cylinder 305 is greater than the friction force between the piston 310 and the water suction rod 306. The water suction rod 306 rises without the piston 310 moving. The water suction rod 306 can drive the limiting plate 2 309 to pull the piston 310 to rise. When the piston rises, it will block the water suction port 307, and in the process of the piston 310 rising, water is sucked into the water suction cylinder 305 through negative pressure. The sucked water passes through the filter cylinder 203, and the filter notch 407 filters floating objects or large particles of impurities in the water, thereby improving the quality of the sample and facilitating detection.

[0041] When the water suction rod 306 rises and then descends, the water suction rod 306 drives the limiting plate 1 308 to descend, so that the limiting plate 1 308 pushes the piston 310 to descend and exposes the water suction port 307. The limiting plate 2 309 blocks the water inlet on the water suction cylinder 305 through the spring 311 and the blocking ball 312, so that the water in the water suction cylinder 305 is discharged into the water suction rod 306 through the water suction port 307, and the water to be tested is transported to the sampling tube 34 through the water suction pipe 31. The excess gas in the sampling tube 34 is discharged through the exhaust valve 32. After the sampling is completed, the sampling tube 34 is taken out and tested. It is convenient for users to quickly take out water samples and quickly sample water samples at the next location, thereby improving the efficiency of water sample collection; the rotating rod 302 drives the rotating rod 401 to rotate, and the rotating rod 401 drives the connecting seat 402 and the cleaning rod 403 to rotate. Because the gear 405 is engaged with the annular gear plate 406, when the cleaning rod 403 drives the gear 405 to move, the gear 405 can drive the cleaning rod 403 to rotate, and the cleaning rod 403 drives the brush 404 to clean the filter slot 407, reducing the accumulation of floating objects in the filter slot 407, which can improve the quality of the water sample and facilitate subsequent detection.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
