The concrete application of the spawning ground monitoring device of 360 degree of rotation monitorings of the present embodiment is as follows:
As it is shown in figure 1, the spawning ground monitoring device that 360 degree rotate monitoring to be transferred to the appointment position in seabed, pass through bracing frame
The spawning ground monitoring device that 360 degree rotate monitoring is supported on seabed, and regulates bracing frame in seabed by regulation spike
Location status, make vertical conduit and vertically rotating shaft be in vertical state in seabed.
Then, it is monitored shooting/taking pictures to spawning ground, in this process by camera head and/or camera arrangement:
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, floating
Ball will move piston body up move along vertical conduit by connecting rope band, in this process vertically the water in mozzle through the
One check valve constantly flows in vertical conduit, and extraneous water flows into and constantly flows in vertical mozzle, thus at vertical water conservancy diversion
Form top-down current in pipe and also drive driving wheel rotation, wheel rotation by vertical rotating shaft drive transparent cabinet and
Interior camera head and/or camera arrangement are around vertical axis of rotation, so that camera head and/or camera arrangement can be 360
In the range of degree, spawning ground is monitored shooting/taking pictures, thus effectively increases camera head or the camera arrangement pair of monitoring device
Spawning ground is monitored the angular field of view shooting/taking pictures.
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
It is positioned at the water of the vertical conduit below piston body during individual and constantly flows into cleaning mozzle through the second check valve, and by
Flushing nozzle ejects towards the lateral surface of transparent cabinet obliquely, thus in transparent cabinet rotation process to transparent cabinet outside
Face is washed away, it is to avoid deposit is attached to the lateral surface of transparent cabinet, thus avoids because monitoring is assembled/be attached to deposit etc.
Equipment surface, and affect the problem that camera head or camera arrangement are monitored the definition shooting/taking pictures to spawning ground.
On the other hand, make piston body move down along vertical conduit at back-moving spring, due to the effect water of the first check valve
Stream forms current from bottom to top in may not flow into vertical mozzle, thus avoids the direction of rotation driving impeller to become
Change, it is ensured that drive impeller to rotate around same direction all the time.
