Description

Water quality detector for seaweed seedling detection Technical Field The invention relates to the technical field of detection equipment, in particular to a water quality detector for seaweed seedling detection. Background The seaweed is used as a key component of an offshore marine ecological system, has multiple ecological values of carbon fixation, oxygen release, water quality purification, bank protection, disaster reduction, and the like, provides habitat and breeding places for marine organisms, and in recent years, the seaweed bed ecological restoration and large-scale artificial seedling industry is gradually raised, so that the seaweed is one of the core works of marine ecological protection and restoration. The sensitivity of seaweed seedling raising to the water environment is extremely high, and the tiny fluctuation of water quality indexes such as water temperature, salinity, pH value, dissolved oxygen, ammonia nitrogen, nitrite and the like can directly influence the germination rate, seedling growth vigor and survival rate of seaweed seeds, even lead to root rot, whitening and death of the seedlings, so that the water quality of a seedling raising pond is accurately and comprehensively monitored in real time, and the seaweed seedling raising method is a key precondition for guaranteeing the seedling raising effect of seaweed and realizing large-scale standardized seedling raising. At present, conventional water quality detection equipment and current seaweed seedling raising matched water quality detectors in the market mostly adopt fixed installation designs, and equipment main bodies or detection probes are hung on and fixed in pool wall positions of a seaweed seedling raising pool, and water quality data acquisition is realized by single-point arrangement. Although the traditional detection equipment can meet the basic detection requirements of small water bodies and simple seedling cultivation scenes, obvious technical limitations exist in large-scale and large-area seaweed seedling cultivation operation, and the traditional detection equipment is difficult to adapt to the actual seedling cultivation production requirements. On one hand, the existing fixed water quality detector has extremely limited detection range, can only collect water quality data of a small-range water body around a probe, can not cover a water body for culturing seedlings Chi Quanyu, and the large-scale seaweed seedling raising pool generally has the characteristics of large water area and wide water body distribution, is influenced by factors such as water body flowability, seedling raising matrix deposition, uneven seedling density distribution, illumination difference and the like, is extremely easy to generate layering and differential distribution of water quality indexes of different areas and different water layers in the pool, and can only represent the water quality condition of local water bodies and can not objectively and comprehensively reflect the overall water quality environment of the seedling raising pool. On the other hand, the water quality regulation and control is carried out by depending on the data detected by the single-point pool wall, the regulation and control deviation is extremely easy to occur, the problems that the local water quality reaches the standard, the remote water body index exceeds the standard, the local water body is excessive in nutrition or pollution is deposited and the like are difficult to discover in time, not only the stable and proper global growth environment cannot be provided for seaweed seedling cultivation, but also the water quality regulation and control cost is increased, the seedling cultivation and control efficiency is reduced, and even the seedling cultivation loss is caused by the water quality assessment misalignment and untimely regulation and control, so that the efficient development of the seaweed large-scale seedling cultivation industry is restricted. Disclosure of Invention In view of the problems that the prior art has fixed single-point layout and limited detection range, only can collect local water data, cannot reflect the global water quality condition of a seedling pool, is easy to cause water quality regulation and control deviation, increases regulation and control cost, reduces seedling management and control efficiency, and is difficult to adapt to the requirements of large-scale seaweed seedling operation, the water quality detector for seaweed seedling detection is provided. The application provides a water quality detector for seaweed seedling detection, which aims to break through the technical limitation of traditional fixed detection equipment, realize real-time accurate comprehensive monitoring of the water quality of a whole seedling pool and multiple water layers, objectively reflect the whole water quality environment, avoid water quality regulation and control deviation, reduce water quality control cost, improve seedlin
