The monitoring device of fish spawning ground protection zone is supported on seabed, spawning ground carried out by camera device and/or camera arrangement
Monitoring shoots/taken pictures.
Buoyant device swims in sea and together fluctuated up and down with the fluctuation of wave.When ball float with the fluctuation of wave toward moving up
When dynamic, ball float will drive piston body up to be moved along vertical conduit by connecting rope, in this process in vertical mozzle
Water is flowed into and constantly flowed into vertical mozzle toward stream in vertical conduit, extraneous water by the first check valve is continuous, so that
Top-down current are formed in vertical mozzle and drive driving wheel rotation, wheel rotation is driven transparent by vertical rotating shaft
Casing and its interior camera device and/or camera arrangement are around vertical axis of rotation, so that camera device and/or camera arrangement can
With in the range of 360 degree spawning ground be monitored and shoot/take pictures, so as to effectively increase the camera device of monitoring device or take pictures
Device is monitored the angular field of view for shooting/taking pictures to spawning ground.
Simultaneously as present invention utilizes the power resources that wave rotates as camera device and/or camera arrangement, so
Do not need power equipment to expend the power supply energy of camera device and/or camera arrangement, thus do not interfere with the continuation of the journey of monitoring device
Time, monitoring device is set to work long hours under water.
When ball float moves down with the fluctuation of wave, back-moving spring makes piston body be moved down along vertical conduit, at this
The water in vertical conduit during individual below the piston body constantly flows into cleaning mozzle by the second check valve, and by
Flushing nozzle ejects towards the lateral surface of transparent cabinet obliquely, on the outside of in transparent cabinet rotation process to transparent cabinet
Face is washed away, and avoids deposit from being attached to the lateral surface of transparent cabinet, so as to avoid because monitoring is assembled/be attached to deposit etc.
Apparatus surface, and influence camera device or the problem of camera arrangement is monitored the definition for shooting/taking pictures to spawning ground.
On the other hand, piston body is made to be moved down along vertical conduit in back-moving spring, due to the effect water of the first check valve
Stream may not flow into vertical mozzle the current formed from bottom to top, so as to avoid becoming in the direction of rotation of driving impeller
Change, ensure that driving impeller rotates around same direction all the time.
