[0020] As Figures 1-3 shown, the present utility model provides a water quality detection and extraction device for a sewage treatment plant, which includes a plurality of sampling bottles 4. A valve is provided at the drainage port 40 of the sampling bottle 4. The sampling bottles 4 are arranged on the front side of a vertical lower probe plate 2. The upper end of the lower probe plate 2 is fixedly connected with a horizontally arranged hanging edge support plate 1. The lower probe plate 2 and the hanging plate support plate 1 form an L-shaped structure. When in use, the lower probe plate 2 is extended downward along the edge into the sewage pool, and the hanging plate support plate 1 is supported on the edge of the sewage pool, so that the device can be effectively supported and installed, which is very convenient. A handle 11 is installed on the hanging edge support plate 1, and it is convenient to extract and place the device through the handle 11.

[0021] A strip groove 20 is vertically opened on the front side wall of the lower probe plate 2. The sampling bottle 4 is installed in the strip groove 20 in an adjustable manner through an adjusting member. An adjusting tooth groove 21 is provided on one side of the opening of the strip groove 20 along its length direction. The strip groove 20 is a T-shaped groove. A T-shaped slider 5 is vertically slidably installed in the strip groove 20. A first sliding hole 501 is horizontally opened at the end of the slider 5 extending out of the strip groove 20 perpendicular to the lower probe plate 2. A first push rod 51 is slidably installed in the first sliding hole 501. A second sliding hole 502 is vertically and communicatively opened at the inner bottom of the first sliding hole 501. The second sliding hole 502 penetrates outward toward the adjusting tooth groove 21 side. A second push rod 52 is slidably arranged perpendicular to the first push rod 51 in the second sliding hole 502. One end of the second push rod 52 extends out of the second sliding hole 502 and is engaged with the adjusting tooth groove 21, and a second spring 54 is provided between the other end and the inner wall of the second sliding hole 502; the outer end of the first push rod 51 is fixedly connected with the sampling bottle 4, and a wedge block 512 is provided at the inner end. An inclined hole 520 matching the inclined surface of the wedge block 512 is opened in the middle of the second push rod 52; A limiting block 511 is fixedly provided in the middle of the first push rod 51 in the first sliding hole 501. A boss 503 is provided on the inner wall of the first sliding hole 501 away from the limiting block 511. A first spring 53 is sleeved on the first push rod 51, and both ends of the first spring 53 are abutted against the boss 503 and the limiting block 511 respectively.

[0022] When the sampling bottle 4 is adjusted vertically, first unlock the fixing of the locking member 341 on the collar 34, then horizontally press the sampling bottle 4 to make the first push rod 51 slide into the first sliding hole 501 and compress the first spring 53. The wedge block 512 at the end of the first push rod 51 will squeeze the inclined hole 520 through the inclined plane, thereby retracting the second push rod 52 into the second sliding hole 502 to unlock the engagement with the adjustment tooth groove 21. At this time, keep the horizontal pressure on the sampling bottle 4 and move the sampling bottle 4 up and down to make the slider 5 move up and down in the strip groove 20, thereby adjusting the vertical height of the sampling bottle 4 and the distance between adjacent samples. After the height of the sampling bottle 4 is adjusted in place, release the pressure on the sampling bottle 4. Under the action of the elastic force of the two springs, the sampling bottle 4, the first push rod 51 and the second push rod 52 rebound and reset. Through the outward extension of the second push rod 52 and the engagement with the corresponding adjustment tooth groove 21, the slider 5 can be locked, and then the height adjustment of the sampling bottle 4 is completed, which is very convenient to use.

[0023] A sealing cover 41 is movably arranged at the upper opening of the sampling bottle 4; a sleeve 33 and a threaded rod are vertically arranged on the front side wall of the lower probe plate 2. The sleeve 33 is slidably installed up and down on the lower probe plate 2, and the threaded rod is threadedly sleeved on the upper end of the sleeve 33. The upper end of the threaded rod is power-connected to the motor 31 on the lower probe plate 2. Specifically, the sleeve 33 is a square tube, and a first mounting seat 302 is fixed on the lower probe plate 2. The sleeve 33 is slidably sleeved in the square opening of the first mounting seat 302. Through the cooperation of the square tube and the square opening, the sleeve 33 can be effectively limited so that it can only slide up and down. A second mounting seat 301 is fixed on the lower probe plate 2, and the upper end of the screw 32 is rotatably installed on the second mounting seat 301. The output shaft of the motor 31 is coaxially fixed to the upper end of the screw 32. By driving the screw 32 to rotate by the motor 31, the sleeve 33 is driven to move up and down stably.

[0024] A collar 34 is movably sleeved on the sleeve 33, and the collar 34 is fixed on the sleeve 33 through a locking member 341. Among them, the locking member 341 can adopt a hand-tightening type quick-fastening bolt, and the quick-fastening bolt is threadedly installed on the collar 34, and its end penetrates through the collar 34 and abuts against the outer wall of the sleeve 33. The quick-fastening bolt can make the tightening and loosening operation of the collar 34 on the sleeve 33 simpler and more convenient.

[0025] A connecting rod 35 is arranged between the collar 34 and the sealing cover 41, and both ends of the connecting rod 35 are horizontally hinged on the collar 34 and the sealing cover 41 respectively. Since both ends of the connecting rod 35 are horizontally hinged on the collar 34 and the sealing cover 41, when the collar 34 moves vertically, the sealing cover 41 will move up and down through the connecting rod. When the sampling bottle 4 drives the sealing cover 41 to move horizontally, using the swing of the connecting rod 35 will not affect the horizontal adjustment action of the sealing cover 41 following the sampling bottle 4, making it more convenient to use.

[0026] When using the utility model, first adjust the height of the sampling bottle 4 and the distance between adjacent sampling bottles 4 according to the water level depth of the sewage tank and the interval height of the water layer to be extracted. When adjusting specifically, first loosen the quick tightening bolt on the collar 34, then press the sampling bottle 4 to retract the second push rod 52 into the second sliding hole 502 to unlock it from the adjustment tooth groove 21. Then, while maintaining the pressure, move the sampling bottle 4 up and down to the adjusted height, release the pressure on the sampling bottle 4, and the second push rod 52 rebounds outward and extends to engage with the corresponding adjustment tooth groove 21. Repeat the above steps to complete the height adjustment of different sampling bottles 4 in sequence. During this period, the connecting rod collar 34 will move up and down synchronously on the sleeve 33. Then, tighten the quick tightening bolt again to fix the collar 34 on the sleeve 33. Place the hanging edge support plate 1 and the downward probing plate 2 beside the sewage tank, start the motor 31 to drive the screw rod 32 to act, the sleeve 33 moves upward, driving all the sealing caps 41 to open synchronously. After the water sample enters the sampling bottle 4 to complete the sampling, the motor 31 rotates reversely to seal the sealing cap 41 on the sampling bottle 4 to prevent the water sample from spilling. Finally, take the device out of the sewage tank and use the valve on the sampling bottle 4 to drain the sewage to complete the sampling.
