Description
Technical Field
The utility model belongs to the technical field of shellfish ammonia discharge rate detects, especially relate to a different water layer shellfish ammonia discharge rate survey normal position experimental apparatus.
Background
In the field of scientific research of aquatic fishery, no special in-situ experimental device is provided for measuring the ammonia discharge rate of shellfish in water bodies with different water layers in the prior art. Generally, the ammonia discharge rate of shellfish with different water layers cannot be directly tested in situ, and is usually tested by indirectly collecting water samples with different water layers or in a laboratory simulation state. The field water condition is greatly influenced by multiple factors, so that the analysis result of the field water condition is larger than the actual shellfish in or out of the field physiological activity, and the deviation occurs, so that the accuracy of the experimental data is reduced.
Disclosure of Invention
The utility model aims to solve the technical problem that a different water layer shellfish ammonia discharge rate survey normal position experimental apparatus is provided, can realize developing the collection to different water layer shellfish ammonia discharge rate survey samples in the normal position in open water.
The utility model provides a technical scheme that its technical problem adopted provides a different water layer shellfish ammonia discharge rate survey normal position experimental apparatus, including floater, raft cage, plummet, connecting pipe and sampling tube, this experimental apparatus includes two sets of shellfish culture assemblies, shellfish culture assembly loops through connecting rope series connection through floater, a plurality of raft cages and plummet and forms, through the connecting pipe intercommunication between two sets of shellfish culture assembly corresponding raft cages, sampling tube one end and connecting pipe intercommunication, the other end are equipped with the gag.
The circumference of the raft cage is of a solid structure, and the upper side face and the lower side face of the raft cage are of screen structures.
The connecting pipe is of a T-shaped three-way pipe structure, and the sampling pipe is connected with the middle branch pipe of the connecting pipe through a threaded structure.
And the connecting pipe is provided with a screen mesh at the port communicated with the raft cage.
The number of the raft cages in the shellfish culture assembly is set to be 3-7.
Advantageous effects
The utility model discloses a multistage raft cage is bred the shellfish of different water layers respectively, leads to in corresponding sampling tube through the water of connecting pipe in with different level raft cages to can realize developing the collection to different water layer shellfish ammonia extraction rate survey samples in the normal position in open water, device simple structure is with low costs, and can reuse, the suitability is strong.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The in-situ test device for measuring the ammonia discharge rate of the shellfish in different water layers shown in figure 1 comprises a floating ball 1, a raft cage 2, a plumb bob 3, a connecting pipe 4 and a sampling pipe 5.
The experimental device comprises two sets of shellfish culture assemblies, wherein the shellfish culture assemblies are formed by sequentially connecting floating balls 1, five-stage raft cages 2 and plumbs 3 in series through connecting ropes. The circumference of the raft cage 2 is of a solid structure made of polyethylene plates, the upper side surface and the lower side surface of the raft cage are of screen mesh structures, the raft cage is used for breeding shellfish with different water layers, and water can freely pass through the raft cage 2 from top to bottom so as to meet the requirement of ingestion of the shellfish.
The raft cages 2 corresponding to the two sets of shellfish culture assemblies are communicated through connecting pipes 4, and the connecting pipes 4 are respectively provided with a screen at the end communicated with the raft cages 2. Take over 4T type tee bend tubular construction for the polyethylene material, sampling tube 5 is the polyethylene pipe, and the middle part branch connection of helicitic texture and connecting pipe 4 is passed through to one end, and the other end is equipped with the gag, can take out the water of collecting in the sampling tube 5 through opening the gag and be used for the ammonia nitrogen concentration of survey water, further converts out the ammonia discharge rate of different water layer shellfish.
