Abstract
The utility model relates to a simple collecting net for buoyancy plankton. The simple collecting net comprises a main net (1), floaters (2) and a heavy hammer (5), wherein the main net (1) encloses to form a cone with open bottom and conic node; the floaters (2) are mounted in the opening of the bottom of the main net (1) and distributed in the opening; the opening of the bottom of the main net (1) is connected with the heavy hammer (5) through a rope; a flowmeter (3) is arranged in the center of the opening of the bottom of the main net (1); a one-way connecting mechanism (6) is mounted in the opening of the conic node of the main net (1) and connected with a hard conic net support. According to the utility model, the simple collecting net has the following advantages: the simple collecting net can be placed horizontally, the accuracy in plankton collection can be effectively improved, escape can be prevented, the production cost is low, and the repeating utilization rate and the practicability are high.
Description
Technical field
The utility model belongs to trawlnet technical field, particularly relates to a kind of simple and easy buoyancy plankton nets.
Background technology
At present domestic in aquatic product fishery field of scientific study, carrying out gathering netting gear conventionally because of water impact effect in the horizontal trawlnet operation process of plankton, produce impulse force and cannot be normally completely floating, be difficult to accomplish netting gear horizontal positioned, the part plankton simultaneously entering in dictyosome also can escape out in dictyosome because of washing away of current, and impact gathers biological accuracy.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple and easy buoyancy plankton nets, and cost of manufacture is low, and recycling rate of waterused is high, practical.
The utility model solves the technical scheme that its technical problem adopts: a kind of simple and easy buoyancy plankton nets is provided, comprise main body etting, float and weight, described main body etting surrounds the taper shape of a bottom and vertex of a cone place opening, float is equipped with at described main body etting bottom opening place, described float is distributed in opening part, described main body etting bottom opening place connects weight by rope, described main body etting bottom opening center arranges a flowmeter, described main body etting vertex of a cone opening part is equipped with a unidirectional gathering unit, described unidirectional gathering unit connects a hard conic net support.
On described unidirectional gathering unit with ball float.
The mesh of described main body etting is greater than the mesh of conic net support.
Described main body etting opening part is equipped with 4 floats.
Described unidirectional gathering unit is check valve.
Beneficial effect
The utility model has the advantage of, can horizontal positioned, effectively improve and gather biological accuracy, prevent from escaping, cost of manufacture is low, and recycling rate of waterused is high, practical.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, a kind of simple and easy buoyancy plankton nets, comprise main body etting 1, float 2 and weight 5, described main body etting 1 surrounds the taper shape of a bottom and vertex of a cone place opening, float 2 is equipped with at described main body etting 1 bottom opening place, described float 2 is distributed in opening part, described main body etting 1 bottom opening place connects weight 5 by rope 4, described main body etting 1 bottom opening center arranges a flowmeter 3, described main body etting 1 vertex of a cone opening part is equipped with a unidirectional gathering unit 6, and described unidirectional gathering unit 6 connects a hard conic net.
On described unidirectional gathering unit 6 with ball float 7.
The mesh of described main body etting 1 is greater than the mesh of conic net support.
Described main body etting 1 opening part is equipped with 4 floats 2.
Described unidirectional gathering unit 6 is check valves.
In practical application, install 2, one flowmeters 3 of 4 floats additional at main body etting 1 bottom opening place, hang a weight 5 by a rope 4 simultaneously, increase a unidirectional gathering unit 6 at main body etting 1 vertex of a cone opening part.Unidirectional gathering unit 6 covers have the support of 4 ball floats 7, on unidirectional gathering unit 6, hard conic net are installed, and the mesh aperture of conic net is less than etting, and conic net support can be changed and clean.
