Water quality detection and sampling device for intelligent aquarium life support system

Abstract

The invention, which relates to the technical field of intelligent aquariums, discloses a water quality detection and sampling device for an intelligent aquarium life support system. The water qualitydetection and sampling device comprises a trough plate; and the outer side of the trough plate is fixedly connected with a first clamping plate. A moving rod enables a screw to move left and right and thus a first sliding plate is driven to move up and down so as to provide a power source of the follow-up operation. When the first sliding plate moves down, a third sliding plate and a second sliding plate falls in a stepped manner and thus sampling can be carried out on water layers with three depths once; a sample bottle moves down and thus a third gear rotates, so that a second gear rotatesclockwise to enable a cover plate to be far away from a discharge hole of the sample bottle; and after sample injection completion, the sample bottle moves up to enable the cover plate to be close toa water injection hole so as to seal the water injection hole, so that the water injection hole is kept to be in a closed state when the sample bottle moves up and down and the water injection hole isin an opening state when being at a sampling position. Therefore, a phenomenon that shallow water enters the sample bottle in sampling of a deep layer and thus errors of sample detection of the deepwater are caused is avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent aquariums, in particular to a water quality detection and sampling device used in a life support system of an intelligent aquarium. Background technique [0002] The aquarium is a place for aquatic life display and popular science education, as well as a place for the protection and research of aquatic biological resources. In order to maintain the life activities of fish in the aquarium, it is particularly important to test its water quality. [0003] Most of the fish in the aquarium are seawater fish. In order to ensure the healthy life of the fish, the water quality needs to be tested regularly. The factors affecting the water quality mainly include water temperature, dissolved oxygen, salinity, nitrogen compounds, pH, hardness, carbon dioxide, phosphoric acid Salt, copper ions, iron ions, silicate, other trace elements and redox potential, such as phosphate, phosphorus is the nutrient salt...

Problems solved by technology

[0003] Most of the fish in the aquarium are sea fish. In order to ensure the healthy life of the fish, the water quality needs to be tested regularly. The factors affecting the water quality mainly include water temperature, dissolved oxygen, salinity, nitrogen compounds, pH, hardness, carbon dioxide, phosphoric acid Salt, copper ions, iron ions, silicate, other trace elements and redox potential, such as phosphate, phosphorus is the nutrient salt for the growth of algae in seawater, but too much phosphorus will make the growth of algae out of control, greatly affecting the viewing effect, And it will seriously pollute the water quality. Most of the uneaten residual bait, fish metabolites and corpses in the water will rot in the water because they cannot be effectively treated. The rotten substances will release a large amount of nitrogen compounds into the water. In the environment, it will slow down the growth rate of aquatic organisms, reduce their immunity, and even cause the death of organisms in severe cases, and because there are many fish in the aquarium, different fish choose to live in different depths of water according to their living habits, and the corresponding The water quality is also different, so it is particularly necessary to detect water layers at different depths. When sampling with existing water quality sampling equipment, it can only be carried out on water layers at the same depth. When detecting water layers at different depths, manual sampling is required. Adjust the drop height of the sampling mechanism. In order to ensure the accuracy of the test results, it is usually necessary to take multiple samples. Frequent adjustment of the height of the sampling mechanism is not conducive to the long-term use of the equipment, and it is easy to shorten its service life, and the operation is also cumbersome.

[0004] Aiming at the deficiencies of the prior art, the present invention provides a water quality testing and sampling device for an intelligent aquarium life support system, which has the advantages of simultaneously sampling water layers of different depths and convenient operation, and solves the problem of inconvenient operation. It can sample water layers of three depths at one time, and the operation is more convenient. When the sample bottle moves up and down, the sample inlet is closed, and when it is in the sampling position, it is open, so as to avoid deep sampling. Shallow water enters the sample bottle, causing errors in the detection of deep water samples
