Abstract
The invention relates to an animal trapper and particularly relates to a benthonic animal trapper with a larger area, which is used for trapping underwater animals. The animal trapper comprises a square base and four square-frame-shaped side walls arranged around the periphery of the square base, wherein bottom edges of the four square-frame-shaped side walls are respectively and movably connected with four edges of the square base and side walls of the four square-frame-shaped side walls are connected two by two through vector-shaped fishing nets; and two radiuses of the vector-shaped fishing nets are respectively connected with adjacent side edges of the two square-frame-shaped side walls. When the trapper is placed below water, the four square-frame-shaped side walls are outwards expanded along the four edges of the square base to form a larger trapping area with the vector-shaped fishing nets, so as to trap the underwater animals on a large scale. Meanwhile, benthonic animals can enter the trapper from all the sides and are not limited by directions.
Description
Technical field
The present invention relates to a kind of animal trap, relate in particular to a kind of seizure larger area zoobenthos catcher of animal under water.
Background technology
In surface water body, many zoobenthos are arranged.People have successively invented the multiple seizure device of zoobenthos under water.The seizure at present more commonly used device of zoobenthos under water is to grab bucket, and its principle is the weight of utilizing trap tool itself to have, sinks under water, and takes out the bed mud of certain area, thereby calculates the macrobenthos quantity in the monitoring waters.Catching area is 1/16 ㎡ or 1/40 ㎡.But its performance also has a lot of not enough, and mainly there are the following problems:
(1) the seizure area of grabbing bucket is 1/16 ㎡ or 1/40 ㎡, can not large tracts of land catch animal under water;
(2) grab bucket because be to rely on the self gravitation effect to collect bed mud, larger to the riverbed interference ratio, cause that bed mud suspends, polluted-water.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of larger area zoobenthos catcher, but when this animal trap gathers zoobenthos not only large tracts of land catch animal under water, collecting efficiency is high, and substantially can polluted-water.
Technical scheme
A kind of larger area zoobenthos catcher, it is characterized in that: comprise a plinth and four square frame-shaped sidewalls that are centered around this square base surrounding, the base of described four square frame-shaped sidewalls is flexibly connected with four limits of plinth respectively and described four square frame-shaped sidewalls are adjacent is connected by fan-shaped fishing net between any two, and two radiuses of described fan-shaped fishing net are connected on the adjacent side of two square frame-shaped sidewalls; When catcher is put into to the bottom, four square frame-shaped sidewalls are along four outside drawouts in limit of plinth; Also be provided with two apertures and rope at described square frame-shaped sidewall away from the top margin both sides of plinth, an end of described rope connects described aperture, and the other end is fixed on a float; Described four square frame-shaped interior are nested with respectively square fishing net.
Wherein, described plinth is comprised of at least three conical socket structures, and the cone point of described conical socket structure injects in soil downwards, on described conical socket structure, is provided with a plurality of through holes.
Wherein, the base of described four square frame-shaped sidewalls is flexibly connected by hinge or is flexibly connected by pivotal axis with four limits of plinth respectively.
Beneficial effect
Compared with prior art, larger area zoobenthos catcher of the present invention has following advantage:
1, the present invention includes a plinth and be centered around four square frame-shaped sidewalls of this square base surrounding, the base of described four square frame-shaped sidewalls is flexibly connected with four limits of plinth respectively and described four square frame-shaped sidewalls are adjacent is connected by fan-shaped fishing net between any two, and two radiuses of described fan-shaped fishing net are connected on the adjacent side of two square frame-shaped sidewalls.When catcher is put into to the bottom, four square frame-shaped sidewalls are along four outside drawouts in limit of plinth, and form larger seizure area between fan-shaped fishing net, can large tracts of land catch animal under water.Zoobenthos can enter catcher from all quarter simultaneously, not limited by orientation.
2, the present invention, due to not disturbance bed mud substantially in capture-process, does not therefore produce secondary pollution to water body, is conducive to protect water ecological environment.
The accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of larger area zoobenthos catcher of the present invention;
In figure: 1, rope, 2, the square frame-shaped sidewall, 3, square fishing net, 4, plinth, 5, fan-shaped fishing net, 6, aperture, 7, float.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.
Larger area zoobenthos catcher as shown in Figure 1 comprises a plinth 4 and is centered around four square frame-shaped sidewalls 2 of these square base 4 surroundings, the base of described four square frame-shaped sidewalls 2 is flexibly connected with four limits of plinth 4 respectively and described four square frame-shaped sidewalls 2 are adjacent is connected by fan-shaped fishing net 5 between any two, and two radiuses of described fan-shaped fishing net 5 are connected on the adjacent side of two square frame-shaped sidewalls 2; When catcher is put into to the bottom, four square frame-shaped sidewalls 2 are along four outside drawouts in limit of plinth 4; And form larger seizure area between fan-shaped fishing net, can large tracts of land catch animal under water.Zoobenthos can enter catcher from all quarter simultaneously, not limited by orientation.
Also be provided with two apertures 6 and rope 1 at described square frame-shaped sidewall 2 away from the top margin both sides of plinth 4, an end of described rope 1 connects described aperture 6, and the other end is fixed on a float 7; Described four square frame-shaped sidewall 2 inside are nested with respectively square fishing net 3.The base of described four square frame-shaped sidewalls 2 is flexibly connected by hinge or is flexibly connected by pivotal axis with four limits of plinth 4 respectively.Animal trap is put into to water-bed 1-2 after week, start to collect catcher.Pull the float 7 on the water surface, thereby pull square frame-shaped sidewall 2 to close by rope 1, with plinth 4, form a square container, reach the purpose of seizure.
Described plinth 4 is comprised of at least three conical socket structures, and the cone point of described conical socket structure injects in soil downwards, on described conical socket structure, is provided with a plurality of through holes.Zoobenthos moves ahead to the placing bait place under the attraction that is subject to bait, crawls into the lowermost end of conical socket structure.Now just make zoobenthos be trapped in lowermost end, and be difficult for climbing out of, can prevent that the animal that enters capture area from escaping.
Above demonstration and described basic principle of the present invention and principal character and advantage thereof.The technology personage of the industry should understand; the present invention is not subject to the restriction of above-mentioned implementing regulations; what in above-mentioned implementing regulations and specification, describe is for principle of the present invention is described; under the prerequisite that does not break away from the principle of the invention and scope; the present invention also can have various changes and modifications, and these changes and improvements all belong in the claimed scope of the invention.
The claimed scope of the present invention defines with appending claims and other equivalent.
