Description
Technical field
The present invention relates to a kind of trap setting, and in particular to one kind is triggered from floating type benthonic shrimp crab sample catcher.
Background technology
Due to the destroying of water area ecological environment, the seriously polluted quality for having influence on existence aquatic products in waters.The opposing party
Face, as the improvement of people's living standards, while aquatic products production and consumption yield is greatly improved, the quality of aquatic products is asked
Topic also increasingly attracts attention.Therefore, the research that whether quality about aquatic products is contaminated influenceing gradually is taken seriously；But
Firstly the need of capture aquatic products sample to be detected before aquatic product quality is monitored.
Current shrimping device is generally the shrimp-catching net of fishery harvesting, shrimp pot etc.；In shrimping by under shrimp-catching net or shrimp pot
It is put into waters, is then after a period of time has passed carried shrimp-catching net or shrimp pot by plant equipment or manually operated mode
Rise, so as to complete a shrimping operating process.Current this fishery harvesting catch Trapping net for shrimp and crab, shrimping crab pot catch it is big, it is simultaneously
For capturing shrimp crab to be detected when not being suitable for monitoring the aquatic product quality in waters.On the other hand, this fishery harvesting is used at present
Catch Trapping net for shrimp and crab, shrimping crab pot need not only to operate inconvenience by way of manual operation to play Trapping net for shrimp and crab or shrimp crab pot, and
Shrimp can be captured by generally requiring multi-pass operation；By its be in deepwater regions shrimping crab it is more inconvenient.
The content of the invention
The invention aims to overcome deficiency of the prior art to be triggered there is provided one kind from floating type benthonic shrimp crab
Sample catcher, its quantity of the catch is small；And it is easy to operate, it can automatically be floated after capture shrimp crab, realize automatic sampling.
The technical scheme is that：
One kind triggering is from floating type benthonic shrimp crab sample catcher, including support frame and some is arranged on support frame
It is described to include the vertical stop collar being arranged on support frame from floating catcher from floating catcher, it is plugged in vertical stop collar
Interior netted shrimping cylinder, gravitation ball and the automatic releasing device being arranged on netted shrimping cylinder, the outside of the netted shrimping cylinder
Face top is simultaneously provided with upper limit position block above vertical stop collar；In the middle part of the netted shrimping cylinder inner bottom surface provided with cross-sectional area certainly
In the middle part of the conical limit guide pin bushing being gradually reduced on down, the upper and lower ends opening of conical limit guide pin bushing, and netted shrimping cylinder bottom surface
Provided with the shrimp-entering mouth corresponding with the lower port of conical limit guide pin bushing, the gravity of the gravitation ball is more than outside buoyancy, gravitation ball
Footpath is more than the internal diameter of conical limit guide pin bushing upper port and less than the internal diameter of conical limit guide pin bushing lower port, and gravitation ball is limited positioned at taper
Below the upper port of position guide pin bushing, and gravitation ball is connected by connecting line with netted shrimping cylinder inner top surface；The netted shrimping cylinder
It is interior to be provided with the buoyant device that netted shrimping cylinder be made to float, and buoyant device is fixedly installed on the lower end of netted shrimping cylinder；It is described
Automatic releasing device includes the position-limiting drum for being vertically arranged in netted shrimping cylinder inner top surface, is arranged on the side surface upper part of netted shrimping cylinder
And the horizontal guide pin bushing below vertical stop collar, the spacing pin in horizontal guide pin bushing is slidably arranged on, limiting block is arranged on

Move to netted shrimping cylinder outside, the touch pole is located at the opposite sides of collar stop with horizontal guide pin bushing, and touch pole is provided with limit
Position fixture block, the position-limiting drum lateral surface is oppositely arranged provided with avoidance through hole, and the avoidance through hole with horizontal guide pin bushing, described to touch
Bar, which is passed through, avoids through hole；Bait pouch is provided with above through hole in the lower ending opening of the position-limiting drum, position-limiting drum and positioned at avoiding.
The quantity of the catch of the shrimp crab sample catcher of this programme is small, suitable for carrying out capture shrimp crab sample different waters
Product, thus use is monitored suitable for aquatic products sample quality, provide shrimp crab sample for monitoring aquatic product quality；And its not only side of operation
Just, and can capture shrimp crab after can float automatically, realizes automatically sample.
On the other hand, because buoyant device is fixedly installed on the lower end of netted shrimping cylinder, when netted shrimping cylinder floats, net
Shape shrimping cylinder makes shrimp-entering mouth upward by occurring upset, and now gravitation ball will block conical limit guide pin bushing under Gravitative Loads, so that
The shrimp crab of capture in netted shrimping cylinder is avoided to be run away by shrimp-entering mouth.
Preferably, buoyant device is annular buoyancy ring, and annular buoyancy ring set is located on conical limit guide pin bushing.This programme
Buoyant device can be floated and after overturning in netted shrimping cylinder, improve the stability and gravity ball sealing of netted shrimping cylinder
The stability of stifled conical limit guide pin bushing.
Preferably, netted shrimping cylinder medial surface top is provided with upset balancing weight.The upset balancing weight of this programme coordinates floating
Power apparatus, which can be effectively ensured after netted shrimping cylinder floats, will occur rotary movement.
Preferably, the length of connecting line is less than the spacing between netted shrimping cylinder upper/lower terminal.
Preferably, cutting ferrule is arranged with spacing pin, and the cutting ferrule is fixed in netted shrimping cylinder by connecting rod
On side, the cutting ferrule is located at the opposite sides of collar stop with horizontal guide pin bushing.
Preferably, also including pull rope from floating catcher, one end of pull rope is connected with netted shrimping cylinder.Traction
Rope can be not only used for transferring catcher, and after netted shrimping cylinder floats can also be conducive to obtaining netted shrimping cylinder.
Preferably, also including decentralization rope, one end of decentralization rope is connected with support frame.Decentralization rope can be used for reclaiming branch
Support, is conducive to the recycling of support frame.
The beneficial effects of the invention are as follows：With quantity of the catch it is small, suitable for aquatic products sample quality monitor use；And operation side
Just, the characteristics of can automatically be floated after capturing shrimp crab, realize automatic sampling.
