Description
Technical field
The present invention relates to harvester, a kind of specifically be used at the bottom of artificial fish shelter or the sea reef on biology and aufwuch harvester.
Background technology
Development along with economic society, owing to reasons such as overfishing and offshore pollutions, the marine eco-environment is subjected to heavy damage, artificial fish shelter and sea reef can improve environments such as subsea, keep somewhere organic, increase the sea area primary productivity simultaneously,, promote the maintenance and the reparation of living marine resources for the marine economy biology provides good nursing ground and feeding ground.
Biology and aufwuch provide good bait for various fishery resources at the end.The research of the biology and the aufwuch succession of community is an important ring of artificial fish shelter research at the end, can disclose the mature condition that artificial fish shelter is grown.
In actual scientific research, adhere to and the biological relatively difficulty of gathering at the end, give at the bottom of the artificial fish shelter on the research of biology and aufwuch brought bigger difficulty, gather facility so demand developing biology and aufwuch urgently at a kind of the end of practicality easy to use.
Summary of the invention
The object of the invention be to provide a kind of be used at the bottom of artificial fish shelter or the sea reef on biology and aufwuch harvester.
For achieving the above object, the technical solution used in the present invention is:
A kind of be used at the bottom of artificial fish shelter or the sea reef on biology and aufwuch harvester, comprise etting and sample collecting bag, harvester is made of steel ring, rope and etting; One end of etting links to each other with the sample collecting bag, and the other end is connected on the steel ring by static line, and steel ring is connected with guide line by the sling that at least two above root head-ropes form.
The other end of described etting is evenly equipped with fixing hole, and static line passes the fixing hole tighten on steel ring.
Described etting from top to bottom is followed successively by top etting, middle part etting, bottom etting, and wherein the top etting links to each other with steel ring, and the bottom etting is connected with the sample collecting bag.
Described top etting is by canvas material or quality softness, and the low and wear-resistant material of permeability rate, middle part etting are nylon or polythene net material, and the bottom etting is the bolting silk material.
Described middle part etting is the nylon or the polythene net material of one deck at least, and the aperture is 30mm.
Top etting and bottom etting aspect ratio are 2: 1, and the bottom etting equates with the height of sample collecting bag.
Described bottom etting is inverted taper type, and upper diameter is 1100mm, and lower diameter is 250mm, and the bottom etting is 0.5mm for the bolting silk aperture.
Described steel ring diameter is 1100mm, and the head-rope vertical height is 800mm, and head-rope is connected to form the most stable taper by sling and steel ring, and the sling that head-rope forms is connected with guide line.
Described sample collecting bag is a hollow cylinder, and is high 400 millimeters, and diameter is 250 millimeters, and the one end is connected with the bottom etting, and the other end tightens up network interface by rope.
The invention has the beneficial effects as follows:
1, the present invention can obviously prevent the escape of biology and aufwuch at the end, has increased the sampling type and the quantity of biology and aufwuch at the end, has improved the accuracy of sampling.
2, the present invention has improved the operating efficiency of gathering biology and aufwuch at the end.
3, etting of the present invention separates with the stainless (steel) wire circle, is convenient to the daily clean and maintenance of facility such as etting; Zhuan Zhi etting part top is for holding the canvas material cylinder-like structure of artificial fish shelter (sea reef) simultaneously, and this structure can be born the friction and the strength thereof of artificial fish shelter (sea reef); The middle part is the nylon material net, and this part is not only supported artificial fish shelter, can filter out biology and aufwuch simultaneously at the end; This facility bottom is a bolting silk material net, and this part is collected top and washed away biology and aufwuch at the end of getting off; The bottommost of this facility is the sample collecting bag of bolting silk material.
4, compare with other similar collection facility, present invention includes canvas material, nylon material and bolting silk material three types, and three types of effects of playing have nothing in common with each other.The top etting permeability rate of canvas material is low, plays the effect that support is held, the wearing and tearing of anti-artificial fish shelter simultaneously; Middle part nylon material netting gear permeability rate is big, plays the effect of supporting the top artificial fish shelter, can make that biology and aufwuch are filled in lower floor's etting at the end simultaneously; Bottom bolting silk material etting network interface is less, plays the effect of holding biology and aufwuch at the end, filtered water stream.
5, the present invention utilizes the current that form in the sampling process, will adhere to that biology and aufwuch are washed in the sample collecting bag at the end, and is easy and simple to handle, alleviated operation easier; Simultaneously this facility prevents biological escape at the end, has increased the species number and the population density of biology and aufwuch at the end.
6. harvester of the present invention is a kind of separate netting gear that connects each other again; This facility can obviously increase aufwuch and biological kind, quantity and efficient of gathering at the end, reduces aufwuch and biologically at the end loses and escape.This facility can make that the collection of biology and aufwuch makes things convenient for efficient quick at the end.
