[0023] The rotating structure 8 includes a mounting shell 81, a motor 82, a first pulley 83, a second pulley 84 and a connecting shaft 85. The mounting shell 81 is fixed to the front side of the top of the movable plate 6, the motor 82 is fixed to the front side of the top of the mounting shell 81, the first pulley 83 is rotatably connected to the front side of the inside of the mounting shell 81, the output shaft of the motor 82 passes through the mounting shell 81 and is fixedly connected to the top of the first pulley 83, the second pulley 84 is rotatably connected to the middle part of the inside of the mounting shell 81, and the second pulley 84 is connected to the first pulley 83 through a belt transmission, and the connecting shaft 85 is fixed to the second pulley. The bottom of the pulley 84, and the bottom end of the connecting shaft 85 passes through the movable plate 6 and is fixedly connected to the top of the threaded rod 9. The diameter of the first pulley 83 is smaller than the diameter of the second pulley 84. When the staff turns on the motor 82, the output shaft of the motor 82 can drive the first pulley 83 below to rotate, and the second pulley 84 is driven to rotate by the first pulley 83 through the belt. The connecting shaft 85 at the bottom of the second pulley 84 can drive the threaded rod 9 below to rotate. Since the diameter of the first pulley 83 is smaller than that of the second pulley 84, the second pulley 84 can rotate slowly.

[0024] The limiting structure 12 includes an electric push rod 121, a limiting plate 122 and a limiting groove 123. The electric push rod 121 is fixed on the front side of the vertical plate 2, the limiting plate 122 is fixed on the front end of the output shaft of the electric push rod 121, and the limiting groove 123 is opened on the front and rear sides of the lifting sleeve 10. The front side of the limiting plate 122 extends to the interior of the limiting groove 123 and is slidably connected to the inner wall of the limiting groove 123. When the threaded rod 9 rotates, the limiting plate 122 is inserted into the interior of the limiting groove 123, thereby limiting the lifting sleeve 10, so that the lifting sleeve 10 can drive the sampling bottle 11 below to move up and down for subsequent wastewater sampling.

[0025] There are several cleaning scrapers 14, and the cleaning scrapers 14 are distributed in a ring with the center of the sampling bottle 11 at the center of the circle. After the sampling bottle 11 rotates, the cleaning scrapers 14 around the sampling bottle 11 can clean the foam and other floating objects on the water surface.

[0026] Guide grooves 15 are provided on the left and right sides of the inner wall of the slide groove 5, and guide blocks 16 are fixed to the rear of the left and right sides of the movable plate 6. The guide blocks 16 are located inside the guide groove 15 and are slidably connected to the inner wall of the guide groove 15. When the output shaft of the cylinder 4 pushes the connecting block 7 to move, the movable plate 6 moves inside the slide groove 5, and the guide blocks 16 also slide inside the guide groove 15, and the movable plate 6 is guided by the guide blocks 16.

[0027] Working principle: when it is necessary to sample the wastewater, the staff pushes the device to the sampling location, and then opens the upper cylinder 4 and the electric push rod 121, so that the movable plate 6 and the sampling bottle 11 below move to the front side. When the sampling bottle 11 moves to the top of the sampling area, the staff can turn on the motor 82 to rotate the threaded rod 9, and the lifting sleeve 10 moves downward on the surface of the threaded rod 9. When the sampling bottle 11 falls above the water surface, the staff opens the electric push rod 121 to move the limit plate 122 out of the limit groove 123. At this time, the lifting sleeve 10 is not limited by the limit plate 122 and rotates with the rotation of the threaded rod 9. The cleaning scraper 14 below the sampling bottle 11 begins to move above the water surface below. The floating foam and other floating objects are cleaned and moved to other positions. After the cleaning is completed, the staff will open the electric push rod 121 again, and the limit plate 122 is inserted into the limit groove 123 on the surface of the lifting sleeve 10, so that the limit plate 122 limits the lifting sleeve 10 again, so that the sampling bottle 11 continues to fall. When the water surface is above the through hole 13 on the surface of the sampling bottle 11, the wastewater will flow into the interior of the sampling bottle 11, and then the wastewater is sampled. After the sampling is completed, the staff controls the output shaft of the motor 82 to reverse, so that the sampling bottle 11 rises again. After rising to a certain height, the staff will turn off the motor 82, and then rotate the sampling bottle 11 to remove the sampling bottle 11 from the bottom of the lifting sleeve 10, so as to complete the sampling of the wastewater.
