[0023] Reference Figures 1 to 6 The embodiment of the utility model is a device for online detection of COD in wastewater in the printing and dyeing industry, which includes a protective shell 1: a pair of support blocks 2 are fixedly connected to the inner wall of the protective shell 1, and a water quality COD online detector 3 is fixedly connected to the top of the pair of support blocks 2. A pair of annular buffer pads 4 are fixedly connected to the inner wall of the protective shell 1, and the top of the protective shell 1 is movably connected to a sealing cover 5 through a hinge, and a vertical block 6 is fixedly connected to the side wall of the sealing cover 5. A bolt 7 passes through the vertical block 6, and a threaded groove matching the bolt 7 is opened on the side wall of the protective shell 1, and a protective groove 8 is provided at the bottom of the protective shell 1. A buffer rubber pad 9 is fixedly connected between the protective groove 8 and the bottom of the protective shell 1, and a placement mechanism is provided below the protective groove 8.

[0024] To facilitate heat dissipation, heat dissipation openings 10 are provided on both side walls of the protective shell 1 , and a dust filter 11 is fixedly connected to the inner wall of the heat dissipation opening 10 .

[0025] It is convenient to unscrew the bolt 7, and a rotating block 12 is fixedly connected to the bolt 7.

[0026] To facilitate the storage of test tubes, the placement mechanism includes a limit bin 13, which is fixedly connected to the bottom of the protective groove 8, and a placement plate 14 is provided in the limit bin 13, a rectangular ring 15 is fixedly connected to the side wall of the placement plate 14, and a plurality of limit grooves 16 are provided on the top of the placement plate 14, a rectangular groove 17 is provided at the bottom of the limit bin 13, a movable block 18 is provided in the rectangular groove 17, a clamping block 19 is fixedly connected to the top of the movable block 18, the top of the clamping block 19 passes through the top of the rectangular groove 17, a clamping groove 20 matching the clamping block 19 is provided at the bottom of the placement plate 14, a spring 21 is fixedly connected between the bottom of the movable block 18 and the inner wall of the rectangular groove 17, and a positioning rod 22 passes through the movable block 18, and both ends of the positioning rod 22 are fixedly connected to the inner wall of the rectangular groove 17.

[0027] To increase friction, anti-slip grooves are provided on the rectangular ring 15 .

[0028] To facilitate placement of multiple test tubes, a plurality of limiting grooves 16 are equidistantly distributed on the placement plate 14 .

[0029] Working principle: When the present invention is used, the sealing cover 5 is opened, the water quality COD online detector 3 is placed in the protective shell 1, and then the sealing cover 5 is closed. The bolt 7 is screwed into the threaded groove on the side wall of the protective shell 1 by the turning block 12. When the water quality COD online detector 3 is used, the bolt 7 is unscrewed by the turning block 12, and the sealing cover 5 is opened for use. At this time, the movable block 18 is pushed downward, and the movable block 18 drives the card block 19 away from the card slot 20, and then the placement plate 14 is pulled out through the rectangular ring 15. At this time, the test tube containing the treated printing and dyeing wastewater is placed in the limit slot 16, and then poured into the water quality COD online detector 3 measuring pool in turn. The operation is carried out in accordance with the requirements of the water quality COD online detector 3 manual, and then the instrument will automatically complete the measurement process and display the measurement results on the display screen. When the detection is completed Finally, press the movable block 18 downward, the movable block 18 drives the card block 19 to move downward, and squeezes the spring 21, and then inserts the placement plate 14 into the limit bin 13, release the movable block 18, and push the movable block 18 upward through the spring 21. The movable block 18 pushes the card block 19 upward and inserts it into the card slot 20 to fix the placement plate 14. When the water quality COD online detector 3 accidentally falls, if the side wall of the protective shell 1 is hit, the impact force squeezes the annular buffer pad 4, thereby absorbing the impact force through the annular buffer pad 4 to protect the water quality COD online detector 3. When the bottom of the protective shell 1 is impacted, the impact force acts on the limit bin 13 and pushes the protective groove 8 through the limit bin 13. The protective groove 8 squeezes the buffer rubber pad 9, thereby absorbing the impact force through the buffer rubber pad 9 to protect the water quality COD online detector 3.
