Therefore, even if a detector carries the machine body to move, the water sample bottle can be kept in a stable state and cannot shake in the detection opening.

Description

Technical Field

[0001] The utility model belongs to the technical field of water quality detection devices, and in particular relates to a water quality detection device for grouper breeding. Background Art

[0002] Grouper farming is a complex process involving multiple links, including the selection of the breeding environment, the selection of fry, feed feeding, water quality management, and disease prevention. Grouper farming can be done in ponds or cages. Pond farming requires digging a pond to simulate the marine environment. The water quality must be clear and pollution-free, and a good circulation and filtration system is required. Cage farming needs to be carried out in sea areas with little wind and waves and less pollution, and the sand and reef conditions on the seabed and the flow rate of seawater must be considered. Whether it is a pond or a cage, it is necessary to ensure that the water quality is stable and suitable for the growth of groupers. Groupers need a good water quality environment for growth. Therefore, it is necessary to regularly test the water quality, including indicators such as pH, ammonia nitrogen, and nitrite, and keep the water quality stable and fresh. At the same time, the breeding density also needs to be controlled to avoid excessive water quality deterioration.

[0003] There are many devices on the market for detecting the good water quality environment required for the growth of grouper. Among them, a small handheld detector is favored for its convenience. However, this handheld grouper aquaculture water quality detector requires the inspector to maintain a relatively stable state during the test to ensure the stability of the sample bottle inside the instrument. But in actual operation, the test process takes a certain amount of time to get the result, which requires the inspector to suspend other work during the on-site testing at the farm and wait for the instrument to complete the test in a stable posture. This practice will undoubtedly limit the work efficiency of the inspector. Therefore, we need to improve these defects of the existing instruments when they are used to improve the efficiency and convenience of the detection work. Utility Model Content

[0020] A hollow column 6 is fixedly mounted on one side of the bottom plate 5 , an extrusion sleeve 9 is mounted inside the hollow column 6 , and a spring 10 is connected to one side of the extrusion sleeve 9 .

[0021] When in use, the grouper breeding water sample is placed in the detection port 4, and then the flip cover 2 is closed, and the detection program is started on the operation screen 3, so that the grouper breeding water sample can be tested, so as to analyze the grouper breeding water quality.

[0022] Preferably: slide grooves 7 are provided on both sides of the hollow column 6 , and bumps 8 are movably installed inside the slide grooves 7 .

[0023] During specific use, when the extrusion sleeve 9 moves, it will drive the protrusion 8 to move, and when the protrusion 8 moves, it will move along the trajectory of the slide groove 7, thereby keeping the moving trajectory of the extrusion sleeve 9 stable, thereby preventing the extrusion sleeve 9 from rotating arbitrarily inside the hollow column 6.

[0024] Preferably, one side of the protrusion 8 is fixedly mounted on the inner wall of the extrusion sleeve 9 , and the maximum diameter of the extrusion sleeve 9 is smaller than the inner diameter of the hollow column 6 .

[0025] During specific use, one end of the extrusion sleeve 9 is located inside the hollow area of ​​the hollow column 6 , and the extrusion sleeve 9 can be extended and retracted in the hollow column 6 .

[0026] Preferably: a recessed notch is provided on one side of the extrusion sleeve 9, the inner diameter of the notch of the extrusion sleeve 9 is adapted to the maximum diameter of the spring 10, the end of the spring 10 away from the notch is connected to the outer wall of the base plate 5, and the base plate 5, the hollow column 6, the slide groove 7, the protrusion 8, the extrusion sleeve 9 and the spring 10 constitute an elastic telescopic structure.

[0027] When in use, the spring 10 inside the extrusion sleeve 9 will maintain its reset state and continuously apply a thrust to one side. This thrust will cause the extrusion sleeve 9 to move along a predetermined track, thereby driving the projections 8 on both sides to move along the track of the chute 7.

[0028] Preferably, the bottom plate 5 is located at the center end of the flip cover 2 , and when the flip cover 2 is closed, the bottom plate 5 , the hollow column 6 and the extrusion sleeve 9 are located directly above the detection port 4 .

[0030] Working principle: First, install the spring 10 inside the extrusion sleeve 9 to ensure a secure installation. Then, weld one side of the hollow column 6 to the surface of the bottom plate 5 to ensure a secure connection. Finally, fix one side of the bottom plate 5 to fit tightly to one side of the outer wall of the flip cover 2 by means of fixed bonding.

[0031] When it is necessary to put the water sample bottle for grouper farming to be tested into the testing port 4, just flip the cover 2 and lock it on the body 1. At this time, the bottom of the squeeze sleeve 9 will be tightly pressed against the top of the water sample bottle. At the same time, the spring 10 inside the squeeze sleeve 9 will maintain its reset state and continuously apply thrust to one side. This thrust will cause the squeeze sleeve 9 to move along a predetermined trajectory, thereby driving the protrusions 8 on both sides to move along the trajectory of the slide groove 7.

[0032] In this way, the squeezing sleeve 9 can move along a fixed path, ensuring that the water sample bottle is stably squeezed and fixed inside the detection port 4.
