[0036] The telescopic assembly 3 includes an octagonal telescopic rod 31 and a circular telescopic rod 32. The octagonal telescopic rod 31 slides inside the circular telescopic rod 32. An octagonal knob 311 is provided at the top of the outermost rod of the octagonal telescopic rod 31, and a beveled tooth column 312 is provided at the bottom of the innermost rod of the octagonal telescopic rod 31. The beveled tooth column 312 is provided with beveled teeth at the bottom.

An annular groove is provided on the beveled tooth column 312, and the four-column plate 261 is provided on the annular groove of the beveled tooth column 312.

[0037] A limiting protrusion 321 is provided between each layer of the circular telescopic rod 32, a locking device 322 is provided at the bottom of each layer of the circular telescopic rod 32, and a spring sheet 323 is provided at the top of the outermost layer of the circular telescopic rod 32. The spring sheet 323 is arranged in an octagonal sleeve at the lower end of the octagonal knob 311.

[0038] Among them, the depth of the collection bottle fixing device 1 in the water is controlled by the extension and retraction of the circular telescopic rod 32, and the octagonal telescopic rod 31 will extend and retract along with the circular telescopic rod 32, and by rotating the octagonal knob 311 on the top of the octagonal telescopic rod 31, the entire octagonal telescopic rod 31 is driven to rotate, and then the beveled tooth column 312 at the bottom of the octagonal telescopic rod 31 controls the rotation of the beveled tooth toggle ring 25, and the four-column spring member 26 ensures that the beveled teeth at the bottom of the beveled tooth column 312 are in meshing state with the beveled teeth 251 of the toggle ring, thereby controlling the opening and closing of the water intake hole 111, and during the process of water intake of the water intake hole 111, when the inspection personnel accidentally rotate the octagonal knob 311 in the opposite direction, the beveled tooth column 312 and the beveled tooth toggle ring 25 will only slide relative to each other, and will not cause the sealing cover plate 21 to close the water intake hole 111, thereby achieving the technical effect of stratified sewage sampling.

[0039] A bottle stopper 41 is provided on the top of the collection bottle 4, a water inlet 411 is provided below the bottle stopper 41, and horizontal plates 412 are symmetrically provided on both sides of the bottle stopper 41. The bottle stopper 41 is arranged in the bottle stopper slide 1112, and the horizontal plates 412 are attached to the side walls of the bottle stopper slide 1112.

[0040] A sealing slide cover 42 is provided on the top of the bottle stopper 41 , and the sealing slide cover 42 is snap-connected with the bottle stopper 41 . The length of the sealing slide cover 42 is greater than the diameter of the bottle stopper 41 . A through hole 421 is provided on the sealing slide cover 42 , and the sealing slide cover 42 slides in the slide cover slot 1113 .

[0041] Among them, before sewage sampling, when the collection bottle 4 is installed on the collection bottle fixing device 1, the horizontal plates 412 on both sides of the bottle plug 41 ensure that the sealing slide cover 42 is opposite to the slide cover slide groove 1113, and the sealing slide cover 42 is pushed into the slide cover slide groove 1113 to ensure that the through hole 421 is connected with the water inlet 411. When the collection bottle fixing device 1 is immersed in water, the sewage enters the collection bottle 4 by controlling the opening of the water intake hole 111, and the sampling of the sewage is completed. At the same time, during the movement of the sealing cover plate 21 to close the water intake hole 111 after the sampling is completed, the slide cover reset member 212 in the cover plate slider 211 will push the sealing slide cover 42 to make the sealing slide cover 42 close the bottle plug 41, thereby completing the closure of the collection bottle 4. When the water intake hole 111 is opened again due to improper operation, it will not affect the sealing of the collection bottle 4 by the bottle plug 41, thereby preventing the collection bottle 4 from being opened twice to contaminate the water sample, thereby affecting the accuracy of the detection.

[0042] During specific use, the collecting bottle 4 is installed in the collecting bottle placement device 12. During the process, the body of the collecting bottle 4 needs to be adjusted so that the wide side of the sealing slide cover 42 faces outward, and then the bottle plug 41 is pushed into the bottle plug slide groove 1112. As the bottle plug 41 is pushed in, the horizontal plate 412 on the side of the bottle plug 41 is squeezed by the bottle plug slide groove 1112, and then the bottle plug 41 is corrected so that the horizontal plate 412 fits against the inner wall of the bottle plug slide groove 1112. At the same time, all the sealing slide covers 42 are pressed into the slide cover slide groove 1113, and it is determined that the water intake hole 111 is in a state of being closed by the sealing cover plate 21.

[0043] According to the height of the layered water intake, the circular telescopic rod 32 is stretched in sections, and the locking device 322 is rotated to fix it. The octagonal telescopic rod 31 will be stretched at the same time as the circular telescopic rod 32. When the collection bottle fixing device 1 reaches the water intake layer, the octagonal knob 311 at the top of the octagonal telescopic rod 31 is rotated 45°, and the spring sheet 323 will limit the octagonal knob 311 so that the octagonal knob 311 can only rotate in multiples of 45°. As the octagonal telescopic rod 31 rotates, the oblique tooth column 312 at the bottom of the octagonal telescopic rod 31 will drive the oblique tooth toggle ring 25 to rotate. The double-column connecting rod 23 connected to the spring slider 24 will push the rotating rod 22 to rotate, and the rotating rod 22 will drive another double-column connecting rod 23 to move, and then drive the cover slider 211 of the sealing cover 21 to slide toward the center, and the water intake hole 111 is opened, and the water to be tested is collected into the collection bottle 4 through the water intake hole 111, the through hole 421 of the sealing sliding cover 42 and the water inlet 411 of the bottle plug 41.

[0044] During the sliding process of the cover slider 211, the sliding cover reset member 212 in the reset member groove 2111 slides on the surface of the sealing sliding cover 42. When the cover slider 211 moves to the innermost side and stops sliding, the protrusion at the bottom of the sliding cover reset member 212 breaks away from the obstruction of the sealing sliding cover 42, and the reset member spring 213 pushes the sliding cover reset member 212 to move downward, and the protrusion at the bottom of the sliding cover reset member 212 slides down to the rear side of the sealing sliding cover 42.

[0045] When there are no more bubbles coming out of the collection bottle 4 on the water surface, the octagonal knob 311 is turned again, thereby driving the helical gear toggle ring 25 to rotate, and the toggle column 252 of the helical gear toggle ring 25 no longer blocks the spring slider 24, and the slider reset spring 241 drives the spring slider 24 to reset, thereby driving the sealing cover plate 21 to move, so that the water intake hole 111 is closed. During the process, the cover plate slider 211 drives the slide cover reset member 212 to move, and the protrusion at the bottom of the slide cover reset member 212 will push the sealing slide cover 42 to move. When the slide cover reset member 212 moves to the inclined protrusion 1114, the inclined surface of the slide cover reset member 212 is pushed by the inclined protrusion 1114 to move the slide cover reset member 212 upward. When the sealing slide cover 42 completely closes the bottle stopper 41, the slide cover reset member 212 no longer squeezes the sealing slide cover 42, and is fixed on the inclined protrusion 1114 with the movement of the cover plate slider 211.
