DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See Figures 1 to 3In the embodiment of the present invention, a rapid water pollution detection device includes an air cylinder 1 and multiple groups of detection tubes 9. The bottom of the air cylinder 1 is provided with an air hole 5, and the air hole 5 is fixedly connected to a threaded sealing cylinder 8. The top of the detection tube 9 is slidably connected to a sliding cylinder 10, and one end of the sliding cylinder 10 is fixedly connected to a sliding sealing plate 11. The sliding sealing plate 11 is slidably connected to the inner wall of the detection tube 9. A spring 12 is provided between the sliding sealing plate 11 and the detection tube 9. The other end of the sliding cylinder 10 is fixedly connected to the sliding cylinder 10. One end is fixedly connected with a threaded connector 17, which is threadedly connected to the threaded sealing cylinder 8. A collection port 18 is provided at the bottom of the detection tube 9, and a sliding sealing tube 20 is slidably connected in the collection port 18. A mixing bucket 21 is fixedly connected to the top of the sliding sealing tube 20, and a water outlet 22 is provided in the side wall of the mixing bucket 21. A second fixing frame 13 is fixedly connected to the sliding cylinder 10, and a drug injection tube 14 is fixedly connected to the second fixing frame 13. The drug injection tube 14 is fixedly connected to the mixing bucket 21. The drug injection tube 1 4 is provided with a liquid guide groove 15 connected with the mixing bucket 21. Before use, the utility model is first injected into the detection tube 9 through the liquid guide groove 15. At this time, the reagent is injected into the mixing bucket 21 along the liquid guide groove 15. Later, when it is necessary to test the water quality, the detection tube 9 is first installed and fixed to the gas cylinder 1 through the threaded connection between the threaded connector 17 and the threaded sealing cylinder 8. Then, the collection port 18 of the detection tube 9 is inserted into the water body, and the gas in the detection tube 9 is sucked into the gas cylinder 1 along the sliding cylinder 10. At this time, the air pressure in the detection tube 9 is reduced. At this time, the water body enters the mixing bucket 21 along the sliding sealing tube 20 under the push of the air pressure difference, and then mixes with the reagent in the mixing bucket 21, and finally enters the detection tube 9 along the water outlet 22. The staff then observes the water body in the detection tube 9, thereby realizing rapid detection of the water body, and after one test is completed, one set of detection tubes 9 can be rotated and removed, and a new set of detection tubes 9 can be screwed into the threaded sealing cylinder 8, thereby realizing rapid replacement of the detection tube 9.

[0019] In one embodiment of the present invention, see Figures 1 to 3 A blocking cap 23 fixedly connected to the sliding sealing tube 20 is provided in the mixing bucket 21. The utility model blocks the bottom of the liquid guide groove 15 through the blocking cap 23, thereby preventing the reagent from entering the sliding sealing tube 20 along the liquid guide groove 15 and flowing out along the sliding sealing tube 20, resulting in loss and waste of reagent.

[0020] In one embodiment of this invention, see Figures 1 to 3A connecting rod 2 is slidably connected inside the gas cylinder 1, and one end of the connecting rod 2 is fixedly connected to a gas plug 4. The gas plug 4 is slidably connected to the gas cylinder 1, and the other end of the connecting rod 2 is fixedly connected to a pull ring 3. The utility model can drive the connecting rod 2 to slide and retract inside the gas cylinder 1 by pulling the pull ring 3, and the connecting rod 2 drives the gas plug 4 to slide and retract, and then the gas in the detection tube 9 is absorbed or injected through the sliding and retracting of the gas plug 4.

[0021] In one embodiment of this invention, see Figures 1 to 3 A sealing port 16 is provided at the top of the injection tube 14, a first fixing frame 6 is fixedly connected to the air hole 5, a sealing plug 7 is fixedly connected to the first fixing frame 6, and the sealing plug 7 is slidably connected to the sealing port 16. The utility model can pre-inject the detection reagent into the mixing bucket 21 along the sealing port 16 and the liquid guide groove 15 before the detection tube 9 is installed. Then, during the process of installing the detection tube 9 on the gas cylinder 1, the sealing plug 7 is inserted into the sealing port 16, thereby sealing the sealing port 16.

[0022] In one embodiment of this invention, see Figures 1 to 3 The sliding sealing tube 20 is fixedly connected to a water drawing tube 19, and the outer diameter of the water drawing tube 19 is smaller than the sliding sealing tube 20. The utility model draws water by setting the water drawing tube 19, and when the water needs to be released, the detection tube 9 can be pulled and the detection tube 9 can be pulled in the direction away from the gas cylinder 1. At this time, the detection tube 9 slides and shrinks from the collection port 18 into the detection tube 9. At this time, the water drawing tube 19 moves into the collection port 18. At this time, since the outer diameter of the water drawing tube 19 is smaller than the sliding sealing tube 20, there will be a drain port between the collection port 18 and the water drawing tube 19. The air plug 4 can be pushed in time to inject the gas in the gas cylinder 1 into the detection tube 9, thereby discharging the water in the detection tube 9 along the drain port.
