A kind of novel artificial fish shelter
Technical field
The present invention relates to aquatic livestock propagation apparatus technical field, particularly a kind of fish multiplication type artificial fish shelter.
Background technology
Artificial fish shelter is artificial structure in marine setting; its objective is and improve the marine site ecotope; build the good environment of marine organisms breath; the place of breeding, growth, forage and protection is provided for biologies such as fishes and shrimps; reach the purpose of protection, propagation and raising catch, can purify water simultaneously and reduce the generation of red tide.Its principle may for: one, artificial fish shelter moves upward current, forms upwelling, and nutritious seawater is brought up, the attraction shoal of fish comes to look for food; Two, artificial fish shelter can produce shade, and many fish are liked shade, comes so be ready to swim across, and is clustered in this; Three, artificial fish shelter can provide the hiding-place of hiding stormy waves and the world to fish.
At present, the material category of existing artificial fish shelter is various, and stone, wooden case, waste tire, waste and old ship etc. are deposited to the seabed, function is relatively poor, and be not suitable as fish shelter facility in the oceanic pasture, particularly for the marine site of silt substrate, anti-mud effect is undesirable.
Summary of the invention
For solving the above-mentioned problems in the prior art, the utility model provides a kind of novel artificial fish shelter, for the marine site of silt substrate, has both considered the situation of sinking to the bottom, fish-gathering effect, has sheltered the fish effect, again cost is optimized, made artificial fish shelter create maximum value with minimum cost.
For achieving the above object, the utility model artificial fish shelter comprises fish shelter base and fish shelter support two parts, and it is characterized in that: described fish shelter base is to be made by armored concrete, and described fish shelter support is that composite is made.
Further, described fish shelter base bottom is provided with four support columns, and the bottom of diagonal angle support column is connected with " ten " font cement beam.
Further, be provided with two crossbeams above the described fish shelter base, support the also composite panel of fixed band circular hole.
Further, described fish shelter support is top little following big landing shape, and bottom and the top surface of support are square, and the housing of support is the composite square tube with certain thickness and hollow.
Further, four of described fish shelter support sides are equipped with a crossbeam.
Further, four sides of described fish shelter support are equipped with composite panel, and the both sides of composite panel and the housing of support all have certain distance, have through hole on the composite panel.
Further, the top of described fish shelter support is provided with composite panel, and the width of this composite panel is less than the tetragonal length of side in top, and length equates that with the square length of side composite panel is provided with through hole.
The shade that artificial fish shelter of the present utility model is made is many, and dead area is big, and it is remarkable to shelter the fish effect.The support column of fish shelter base can prevent that the main body of artificial fish shelter from sinking in the silt in seabed.The employed composite panel of fish shelter is equipped with through hole, is convenient to leak silt.Whole artificial fish shelter simple in structure, multiple functional, easy to make, consumptive material is few, and cost is low.

Fig. 1 is the structural representation of artificial fish shelter among the embodiment;
Embodiment
The utility model, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment in order further to explain.Should be appreciated that specific embodiment described herein only in order to explain the utility model, does not limit the utility model.
Embodiment:
As shown in Figure 1, the base 2 of artificial fish shelter is provided with four support columns 21, and the cross section of each support column is square.Be provided with cruciform girder 22 between two support columns in diagonal angle, play the effect of support and anti-mud.The upper surface of artificial fish shelter base 2 is provided with two crossbeams 23, support and fixing composite material plate 11, make shade and protect the place for fish, be evenly equipped with a plurality of through holes on the composite panel 11, can prevent sedimentation, play the space of playing for immature fish provide simultaneously.Artificial fish shelter support 1 is big little trapezoidal shape down, and four sides of support are equipped with crossbeam 13 and composite panel 12, and composite panel 12 is provided with two through holes, is convenient to fish and shuttles back and forth.The end face of artificial fish shelter is provided with composite panel 15, and through hole is set on it, for fish provide shade and protect the place.Artificial fish shelter base of the present utility model adopts armored concrete to make, and not only cost is low, and durable in use.The artificial fish shelter support adopts composite, and the place of breeding, growth, forage and protection can effectively be provided for fish.
Although be the example purpose, preferred embodiment of the present utility model is disclosed, it also is possible those skilled in the art will recognize various improvement, increase and replacement, therefore, scope of the present utility model should be not limited to above-described embodiment.
