Abstract

The present invention relates to a multifunctional plankton catcher for collecting plankton from fresh water or seawater comprising: a first filter part for collecting relatively large-sized macroplankton; and a second filter part for collecting meso and micro plankton. Since a circular net in the first filter part and a fabric net in the second filter part can be replaced with nets whose meshes vary in size, one plankton catcher can perform a role as a number of plankton catchers. Additionally, a handle or a string can be selectively combined in the first filter part, thereby being able to be used in many ways depending on the place and collecting methods. And an exclusive collection bottle can be combined with the catcher if combining a bottle cap with a cock in the second filter part so that the convenience in handling is increased enough to control with one hand and the applicability is improved by allowing a funnel or a lid to be combined with the cock. Lastly, the plankton catcher can be made of metal or plastic selectively so that the weight and manufacturing costs are adjustable, thereby being able to be produced and used as a tool for education as well as research.

Description

{Multifunctional plankton net}

The present invention relates to a plankton collecting net for collecting plankton inhabiting seawater and fresh water, and more particularly, to a plankton collecting net for collecting plankton in seawater and fresh water, and more particularly, The present invention relates to a multifunctional plankton collecting net which can be easily operated by combining bottles at the lower end of a cock, and designed to use a handle or a string according to collection situations.

To collect plankton inhabiting seawater or freshwater, a plankton net or a plankton net is used. The tool typically connects a fabric net with a round ring of metal wrapped in a durable fabric to filter the water, the mesh is in the form of an inverted cone that tapers downward and the cock is mounted at the bottom . The plankton is collected by hanging a line on the circular ring side of the plankton collecting net and putting it in the water and pulling the line, and the water is filtered and the creatures in the water are collected in the lower part.

Since plankton inhabits in a wide variety of sizes, plankton harvesting nets with various mesh sizes are commercially available. However, since plankton harvesting network is expensive equipment because it is specialized equipment used in life sciences field, it is difficult to have a lot of budget in order to have various plankton collecting networks in elementary, middle and high schools. In addition, when preparing multiple plankton collecting nets, transportation problems arise because they take up a large amount of mass and volume. In addition, it is an inconvenient and cumbersome process for adults as well as for the underprivileged to do the work of opening cocks and putting collecting bottles on their own. Finally, the plankton harvesting net is usually hoped for by dragging a ship on a ship, and when collecting with students, it is often collected on the coast rather than this way. However, there is a problem in that it is inefficient because it is difficult to move the plankton harvesting network as desired.

In order to solve the above-mentioned problems of existing plankton collection networks, the present invention can be used to separate or combine plankton collection networks according to the purpose of the plankton collection network, It is a technical task to not only carry out collecting for various purposes but also to be convenient for transportation by reducing mass and volume.

In addition, the present invention improves the conventional method that requires the hands of several persons when opening the cock and puts the collected product in a bottle, so that it can be carried out by itself, and also enables easy use of the plankton collecting net even on the coast. Is another technical problem to be solved.

The present invention as a first means for solving the above technical problems is characterized in that the plankton collecting net is divided into a first filtration section and a second filtration section so that only the first filtration section is used alone, The filter net of the round net and the filter net of the second filter part can be used by replacing the mesh net according to the size of the plankton to be collected, .

According to the present invention as a second means for solving the above-mentioned technical problems, a collection bottle can be easily collected alone by allowing a dedicated collection bottle to be connected to the lower end of the second filtration part, A plurality of holes can be used to connect the lines, and a plankton collecting net can be used to hold the knob so that various usages can be applied.

According to the present invention as described above, in order to collect relatively large macroplankton such as a mackerel or a pest in the coast, it is possible to insert and attach a relatively large net mesh to the first filtration part, Depending on the size of the plankton to be used, it is possible to use the circular network inside the first filtration unit instead of the plural plankton collecting net, and to use it by replacing the circular net with the mesh of different meshes, and the plankton below the meso microplankton It is possible to use the second filtration unit in combination with the first filtration unit and to use the cloth mesh of the second filtration unit according to the size of the plankton to be collected by replacing it with another cloth mesh.

In addition, it is possible to collect the collected material easily by allowing the dedicated collection bottle to be connected to the lower end of the second filtration part. If the dedicated collection bottle is not used, the funnel can be combined to move the collected material When the plankton collecting net is not used, there is an effect that the lid can be combined and stored in order to prevent contamination of the inside of the cock.

In addition, since the plankton collecting net can be prevented from being connected to a hole located in the first filtering section, and the plankton collecting net can be used more conveniently on the coast by joining the handle to the first filtering section, It can be used in various ways according to the situation and place of using the collection network.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, the plankton collecting net according to the first embodiment of the present invention is divided into two parts, that is, the first filtering part 10 shown in FIG. 3 and the second filtering part 20 shown in FIG. 5 to 6, the first filtration part 10 is constituted by four parts including a circular mesh coupling part 11, a circular mesh 12, a second filtration part coupling part 13, and a knob 14, The circular net 12 is inserted between the circular mesh connecting part 11 and the second filtering part connecting part 13 to be coupled. At this time, each of the circular mesh connecting portion 11 and the second filtering portion connecting portion 13 has threaded concavities and convexities so that the respective portions can be rotated or combined or separated. The mesh of the circular net (12) can be manufactured in various sizes and can be installed by changing the circular net (12) having different mesh. This can reduce the economic burden caused by having a plurality of plankton collecting net separately, It is advantageous to reduce mass and volume.

1 and 3, when the handle 14 is coupled to the handle engagement portion 16, the plankton gathering net can be gripped with one hand and the groove on the handle engagement portion 16 and the The shape of the groove and the projection and the manner of engaging the knob 14 with the grip engaging portion 16 may be different from the shape of the groove 14. [ May be applied. In addition, a knob rubber 15 was attached to the knob 14 to prevent the plankton gathering net from being missed in the water. Although not shown in the drawings, the knob rubber 15 has various irregular patterns on the surface of the knob rubber 15, The frictional force can be further increased.

As shown in FIG. 3, when only the first filtration part is used, relatively large large plankton such as mackerel and pest can easily be collected on the coast. In order to collect the medium and small plankton, the first filtration unit 10 may be combined with the second filtration unit 20 shown in FIG. 4, which is shown in a perspective view in FIG. 5 to 6, the second filtration portion includes a fabric net coupling portion 21, a fabric net 22, a cock coupling portion 23, a cock 24, a bottle cap 25 for coupling a cock, (31). The wide hole side of the inverted cone-shaped cloth net 22 is inserted between the second filtration portion coupling portion 13 of the first filtration portion 10 and the fabric net coupling portion 21, (13) and the fabric net engaging portion (21). That is, the upper end portion of the fabric net 22 is tightly fixed between the second filter portion engaging portion 13 and the fabric net engaging portion 21 to be firmly fixed. Then, the narrow hole side of the fabric net 22 is inserted between the cock engaging portion 23 and the cock 24, and then the cock engaging portion 23 and the cock 24 are engaged. That is, the lower end of the fabric net 22 is tightly fixed between the cock engaging portion 23 and the cock 24 and is firmly fixed. 6, there are threaded projections and depressions at the adjacent portions between the second filter portion engagement portion 13 and the fabric net engagement portion 21 and between the cock engagement portion 23 and the cock 24 Therefore, the two parts can be rotated or joined together or separated. When the plankton collection network is used in a state where the first filtration part 10 and the second filtration part 20 are combined with each other, the plankton is smaller than the mesh size of the circular mesh 12 and larger than the mesh size of the mesh net 22 And the circular net 12 functions to prevent undesired foreign matter from being collected. The cloth net 22 may be made of various materials, but generally a thin nylon fabric is used in a large amount. The woven net 22 of the net 22 mainly has a mesh net having a mesh size of 5 to 1,400 μm. Since a variety of woven fabrics can be used depending on the size, there is an effect that the utilization range of one plankton gathering net becomes very wide.

The bottle cap 25 for coupling the cock is first joined to the lower end of the cock 24 and then the exclusive small collection bottle 31 is used in combination. The dedicated large collection bottle 32 of FIG. 5 may be used have. Only a special small collection bottle 31 and a dedicated large collection bottle 32 are separated from the cock 24 after the collection, The lid 33 can be closed to safely transport and store the collected material without pouring it.

When a bottle or a container other than the dedicated collection bottle is used, the cock-binding funnel 26 can be coupled to the lower end of the cock 24 to precisely transfer the collected product. The shape of the funnel for the cock or cock is expressed in the general form and it can be made variously according to the convenience of the user and the container which is frequently used. Also, after the plankton collecting net is transported or used and cleaned, the cock lid 27 is coupled to the cock 24 to prevent foreign matter from entering into the cock, thereby preventing contamination.

As shown in FIG. 2, the plankton collecting net can be used in a manner that is expected to be achieved by separating the handle 14 and then connecting the line to the line connecting portion 17, so that the plankton collecting net can be selected in accordance with the gathering place or situation .

The circular net 12 and the cock 24 except the cloth net 22 and the handle rubber 15 are made of a metal material such as stainless steel which does not rust in water and all other parts are made of a plastic material It has been devised as an embodiment of the invention, but it can be made for the weaker students that all parts can be made of relatively light plastic material, and conversely, if the emphasis is on durability, all parts can be made of metal Come on.

As described above, according to the present invention, it is possible to replace various net meshes in one plankton collecting net, to use the cock and the bottle more conveniently, and to select and use the handle and the line. Therefore, And it can be used variously according to material and cost, so that it can be used for education, research and academic use.
