Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, a kind of fixed point fish-egg auxiliary monitoring device, comprising: clump weight 1, the suspension rack 3 and the master that suspend in water Dynamic capture type fish-egg auxiliary device 4.
Clump weight sinks to seabed.
It is connected between clump weight and suspension rack by connecting rope 2.
As shown in Figure 1, Figure 2, Figure 3 shows, active capture type fish-egg auxiliary device includes the fixed vertical sleeve being arranged on suspension rack 4.1, it is installed on the tripping sleeve 4.2 that is slidably arranged on surely vertical sleeve, the annular being arranged on surely vertical sleeve lateral surface Plate 4.3 and annular lower installation board 4.4 and several from-inner-to-outers are sequentially sleeved at the attachment net cylinder 4.5 outside surely vertical sleeve.
The lower end closed of fixed vertical sleeve, the upper end opening of fixed vertical sleeve.Positioned at annular upper mounting plate and the lower peace of annular Fixed vertical sleeve between loading board be equipped with it is several be connected to lateral surface in fixed vertical sleeve cross water through-hole 4.7.Fixed vertical sleeve Lateral surface on and be located at the lower section of annular lower installation board and be equipped with the drainpipe 4.9 being connected with surely vertical sleeve, in drainpipe Equipped with second one-way valve 4.10.Second one-way valve allows the seawater in surely vertical sleeve to be discharged to the external world by second one-way valve.
The upper and lower ends of tripping sleeve are open.The upper end of tripping sleeve is located at the top of fixed vertical sleeve.Tripping sleeve Lower end is located between annular upper mounting plate and annular lower installation board.The lateral surface of tripping sleeve is equipped with sleeve floating block 4.6, floats Sleeve is floated across the sea by sleeve floating block, and the first check valve 4.8 is equipped in the lower port of tripping sleeve.First check valve is permitted Perhaps the first check valve of seawater in fixed vertical sleeve enters in tripping sleeve.
Adhere to net cylinder to be located between annular upper mounting plate and annular lower installation board.
Attachment net cylinder includes the mesh sheet of annular.It is gradually reduced by the mesh for the attachment net cylinder being sequentially distributed inside outside.
Annular lower installation board is fixed on the lateral surface lower part of surely vertical sleeve.The lower end surface of attachment net cylinder, which is against under annular, pacifies On the upper surface of loading board.The upper surface of annular lower installation board is equipped with and the attachment one-to-one annular spacing groove of net cylinder, attachment net The lower end of cylinder is located in corresponding annular spacing groove.
The upper surface of attachment net cylinder is against on the lower surface of annular upper mounting plate.Annular upper mounting plate includes being set in erect surely Installation set 4.31 on straight sleeve, the ring plate 4.32 being arranged on installation set lateral surface and it is arranged in installation set for will Installation set is fixed on the holding screw on surely vertical sleeve.Annular upper mounting plate is fixed on surely vertical sleeve by holding screw On.
The specific works of the fixed point fish-egg auxiliary monitoring device of the present embodiment are as follows:
As shown in Figure 1, launching fixed point fish-egg auxiliary monitoring device into specified sea area.
Tripping sleeve utilizes the fluctuation of wave, constantly float up and down (when sleeve floating block is in wave wave crest, tripping sleeve Rise to high point;When sleeve floating block is in wave trough, tripping sleeve drops to low spot);
During tripping sleeve is moved up along fixed vertical sleeve, the first check valve prevents the underwater stream in tripping sleeve, thus outer The seawater on boundary will enter fixed vertical sleeve by crossing water through-hole, and fixed vertical set will be entered by crossing water through-hole by forming extraneous seawater The water flow of cylinder;In this process, extraneous seawater will pass sequentially through each attachment net cylinder, and seawater will drive water in this process Most fish-egg in the fish-egg of middle floating will be attached in attachment net cylinder;
In tripping sleeve along fixed vertical sleeve folding process, the first check valve is opened, and second one-way valve is opened, vertical because depending on Water in sleeve is hardly extruded, i.e., the water flow that the water in vertical sleeve is outflowed by crossing water through-hole will not be generated, to keep away The fish-egg for exempting to be attached in attachment net cylinder is washed disengaging.
In this way, the fish-egg that can effectively improve in the seawater near active capture type fish-egg auxiliary device is attached to attachment Adhesive rate in net cylinder, thus the case where more reliably reacting the fish-egg quantity in the seawater.
After a period of time, such as after two weeks, fixed point fish-egg auxiliary monitoring device is lifted, is taken out, by attachment net cylinder Fish-egg, research and analysis is carried out to the oviposition situation in fish spawning ground.
