[0003] For example, the oxygen content detection device for aquaculture water quality with the announcement number "CN219065447U", the moving plate is moved up and down by the rotation of the rotating column, so that the lifting plate fixedly connected with the moving plate is moved up and down, so as to change the height of the oxygen content detector, and the oxygen content detector is lifted to facilitate the water quality oxygen content test of water of different depths, effectively placing the oxygen content in water quality is insufficient. However, the above-mentioned oxygen in water is detected, because the length of the lifting plate is fixed, the staff needs to detect the water area at a certain distance, so that the working safety is low during the detection process near the water area, and the staff needs to rotate the detection disc reciprocally when driving the detection head into the water and separating from the water, the operation process is more complicated, and the practicability is low.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] An automatic water body oxygen concentration detection device is designed, which comprises a box body and a dissolved oxygen meter, the dissolved oxygen meter is fixedly connected to the outer wall of the box body through a support, the right side of the outer wall of the box body is provided with an automatic water body oxygen concentration detection structure, the left side of the outer wall of the box body is provided with a position adjusting structure, the lower end of the inner wall of the box body is slidably connected with two scrapers, the outer wall of the scraper is provided with a spring, and the two ends of the spring are fixedly connected with the scraper and the box body.

[0007] Preferably, the automatic water oxygen concentration detection structure includes a motor, a worm gear fixedly connected to the end of the motor output shaft, the two ends of the worm gear being rotatably connected to the housing via bearings, the outer wall of the worm gear meshing with a worm wheel, the rotating shaft of the worm wheel being rotatably connected to the housing via bearings, a spool fixedly connected to the rotating part of the worm wheel, the rotating shaft of the spool being rotatably connected to the housing via bearings, and a cable wound around the upper end of the outer wall of the spool.

[0008] Preferably, the outer wall of the motor is fixedly connected to the housing via a bracket, and the upper end of the cable is electrically connected to the dissolved oxygen meter.

[0009] Preferably, the outer wall of the cable is in contact with the two scrapers, and the end of the cable is electrically connected to the detection head.

[0010] Preferably, the position adjustment structure includes a housing, with two sliding rods fixedly connected to the inner wall of the housing, the outer walls of the sliding rods slidably connected to a cross plate, the outer walls of the cross plate slidably connected to the housing, the right ends of the two cross plates fixedly connected to the box body, and an electric telescopic rod fixedly connected to the middle of the inner wall of the housing, the output end of the electric telescopic rod fixedly connected to the box body.

This allows the spool to unwind the cable wound around its outer wall. The motor then drives the detection head to move up and down, transporting the detection head to the detection area and retrieving it. This reduces manual operation steps, making the process more automated and convenient, and significantly improving practicality. Attached Figure Description
