The concrete application of the littoral zone fisheries conservation seabed monitoring system of the present embodiment is as follows:
As it is shown in figure 1, littoral zone fisheries conservation seabed monitoring system to be transferred to the appointment position in seabed, will by bracing frame
Spawning ground, in seabed, is carried out by littoral zone fisheries conservation seabed monitoring system support by camera head and/or camera arrangement
Monitoring shoots/takes pictures.
Buoyant device swims in sea and the fluctuation with wave is fluctuated the most up and down.When ball float up moves with the fluctuation of wave
Time dynamic, ball float will move piston body by connection rope band and up move along vertical conduit, in this process in vertical mozzle
Water constantly flows through the first check valve in vertical conduit, and meanwhile, the water in vertical conduit above piston body is single through the 4th
Constantly flow in vertical mozzle to valve, thus in vertical mozzle, form top-down current and drive driving impeller
Rotating, wheel rotation drives transparent cabinet and interior camera head thereof and/or camera arrangement around vertical rotating shaft by vertical rotating shaft
Rotate, so that camera head and/or camera arrangement can be monitored shooting/taking pictures in spawning ground in the range of 360 degree, from
And effectively increase the camera head of monitoring device or camera arrangement is monitored the angular field of view that shoots/take pictures to spawning ground.
Simultaneously as present invention utilizes the power resources that wave rotates as camera head and/or camera arrangement, so
Need not power equipment and expend camera head and/or the power supply energy of camera arrangement, thus do not interfere with the continuation of the journey of monitoring device
Time, monitoring device is enable to work long hours under water.
When ball float moves down with the fluctuation of wave, back-moving spring makes piston body move down along vertical conduit, at this
Water extraneous during individual is flowed in vertical conduit by the 3rd check valve, meanwhile, is positioned at vertical conduit below piston body
Water constantly flows into cleaning mozzle through the second check valve, and is sprayed towards the lateral surface of transparent cabinet obliquely by Flushing nozzle
Go out, thus in transparent cabinet rotation process, transparent cabinet lateral surface is washed away, it is to avoid deposit is attached to transparent cabinet
Lateral surface, thus avoid because monitoring device surface is assembled/be attached to deposit etc., and affect camera head or camera arrangement pair
The problem that spawning ground is monitored the definition shooting/taking pictures.
On the other hand, make piston body move down along vertical conduit at back-moving spring, due to the first check valve and the 4th list
In the effect current of valve may not flow into vertical mozzle, form current from bottom to top, thus avoid in the rotation driving impeller
Direction changes, it is ensured that drive impeller to rotate around same direction all the time.
