In water air pump inoperative, under the buoyancy of upper scaffold, piston body will up be moved along vertical cylinder body, make piston
Body is against on annular upper limit position block.
It is specifically used as follows:
Open water pump, headlamp and monitor camera；Then, sinking type spawning ground monitoring device is transferred to by connecting rope 1a
Seabed, sinking type spawning ground monitoring device is supported by pedestal 1 and seabed.
(fish-egg can pass through the net of filtering net cylinder after pump working, extraneous seawater and fish-egg are filtered by filtering net cylinder
Hole), the fish-egg in seawater is entered in vertical cylinder body with seawater by water inlet, is then pumped out by drainage joint, connecting tube and water
The mouth of a river be expelled back into it is marine (seawater can smoothly by water inlet enter vertical cylinder body, then under the buoyancy of upper scaffold,
Holding is against on annular upper limit position block by piston body)；In this process, headlamp observes interface by cylinder body and cabinet is observed
Interface is that light source is provided in vertical cylinder body, and monitor camera observes interface by cylinder body and cabinet observes interface in vertical cylinder body
Seawater in fish-egg carry out shooting monitoring, as extraneous seawater constantly enters in vertical cylinder body, so can effectively improve
Effect increases the monitoring region of monitoring device, and the limitation at the visual angle of device not monitored and underwater obstacles.
In addition, with increasing for the attachment filtered on filtering net cylinder, attachment will block during pump working
The mesh of screen tube enter seawater can not by water inlet in vertical cylinder body, at this point, as the intracorporal water of vertical cylinder is by water pump
Extraction, piston body 5 will overcome the buoyancy of upper scaffold, will move down along vertical cylinder body, until piston body is against annular lower limit
On block；During moving down along vertical cylinder body, cleaning set and bristle will move down together with piston body, to pass through bristle
It will be cleaned up with the attachment on filtering net cylinder, extraneous seawater enable smoothly to enter vertical cylinder body by water inlet；
After extraneous seawater smoothly can enter vertical cylinder body by water inlet, piston body is by under the buoyancy of upper scaffold, edge
Vertical cylinder body up moves, and is against piston body on annular upper limit position block, while cleaning set and bristle being driven to move up reset together,
So guarantee that filtering net cylinder is not attached to object blocking, enables the prolonged work well of sinking type spawning ground monitoring device.
