Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, the monitoring device of protection zone, a kind of Fish spawning ground is included buoyant device 21, connects rope 20, bracing frame 1, the transparent cabinet 8 being rotatably provided on bracing frame by vertical rotating shaft 5, the vertical conduit 2 being arranged on bracing frame, the piston body 15 being slidably arranged in vertical conduit, is arranged on vertical conduit medial surface and is positioned at the lower position block 14 below piston body, piston body can be made to move down back-moving spring 16, the vertical mozzle 3 being arranged on bracing frame and the cleaning mozzle 10 being arranged on bracing frame resetted.Transparent cabinet is positioned at the lower section of vertical conduit.There is in transparent cabinet sealed internal chamber.Transparent cabinet is cylindrical, and transparent cabinet is coaxial with vertical rotating shaft.Being provided with camera head 9 and/or camera arrangement in sealed internal chamber, the camera head of the present embodiment is video camera, and camera arrangement is photographing unit.The power supply of camera head and/or camera arrangement is positioned at transparent cabinet.The photographic head of camera head is arranged in the horizontal direction.The camera lens of camera arrangement is arranged in the horizontal direction.
The vertically upper end open of conduit, lower end closed.Vertically it is provided with web plate 18 in the upper end open of conduit.Back-moving spring is between web plate and piston body.Vertically on conduit medial surface and be positioned at the upper limit position block 17 above piston body.Vertically the surface of conduit is provided with connection rope spacing ring 19.Connect above the middle part of the upper end open that rope spacing ring is positioned at vertical conduit.Buoyant device is buoyant spheres.The one end connecting rope is connected with buoyant device, is connected in the other end is down stretched into vertical conduit by the upper end open of vertical conduit and with piston body.Connect rope through connecting rope spacing ring.
Vertically the upper end open of mozzle, lower end are connected with vertical conduit by the first connecting tube 7.First connecting tube is positioned at the lower section of lower position block.The first check valve 6 it is provided with in first connecting tube.First check valve allows current to be flowed from vertical mozzle toward vertical duct direction.Vertically one end of rotating shaft is stretched in vertical mozzle, specifically, is provided with and dodges hole in the middle part of the lower end of vertical mozzle, and the upper end of vertical rotating shaft is through dodging hole and stretching in vertical mozzle.Vertically in rotating shaft and be positioned at vertical mozzle and be provided with driving impeller 4.
The one end cleaning mozzle is connected with vertical conduit by the second connecting tube 13, and the other end is towards the side of transparent cabinet.Second connecting tube is positioned at the lower section of lower position block.The second check valve 12 it is provided with in second connecting tube.Second check valve allows current from vertical conduit toward cleaning the flowing of mozzle direction.Being located at Flushing nozzle 11 towards one end cleaning mozzle of the side of transparent cabinet, this Flushing nozzle sprays obliquely towards the side of transparent cabinet.Camera head and/or camera arrangement are positioned at cleaning mozzle and the lower section of Flushing nozzle.
The concrete application of the monitoring device of the protection zone, Fish spawning ground of the present embodiment is as follows:
As it is shown in figure 1, the monitoring device of protection zone, Fish spawning ground to be transferred to the appointment position in seabed, by bracing frame, the monitoring device of protection zone, Fish spawning ground is supported on seabed, is monitored shooting/taking pictures to spawning ground 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, ball float will move piston body by connection rope band and up move along vertical conduit, water in vertical mozzle constantly flows through the first check valve in vertical conduit in this process, extraneous water flows into and constantly flows in vertical mozzle, thus in vertical mozzle, form top-down current and drive driving wheel rotation, wheel rotation drives transparent cabinet and interior camera head thereof and/or camera arrangement around vertical axis of rotation by vertical rotating shaft, so that camera head and/or camera arrangement can be monitored shooting/taking pictures in spawning ground in the range of 360 degree, thus 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, owing to 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 cruising time of monitoring device, enable monitoring device 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, the water being positioned at the vertical conduit below piston body in this process constantly flows into cleaning mozzle through the second check valve, and ejected towards the lateral surface of transparent cabinet obliquely by Flushing nozzle, thus in transparent cabinet rotation process, transparent cabinet lateral surface is washed away, deposit is avoided to be attached to the lateral surface of transparent cabinet, thus avoid because monitoring device surface is assembled/be attached to deposit etc., and affect the problem that camera head or camera arrangement are monitored the definition shooting/taking pictures to spawning ground.
On the other hand, piston body is made to move down along vertical conduit at back-moving spring, form current from bottom to top in may not flow into vertical mozzle due to the effect current of the first check valve, thus avoid the direction of rotation driving impeller to change, it is ensured that drive impeller to rotate around same direction all the time.
