Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Aiming at the defects of the traditional culture equipment submergence and descent system, the submergence and descent system mainly adopts a winch-anchor chain fixing device and a floating frame-air pump buoyancy adjusting device for submergence and descent. The winch-anchor chain fixing system can ensure that the anchor chain is descended, keep the tension of the anchor chain in the return process and limit the horizontal displacement of the aquaculture net cage. When the winch is in a working state and a submergence completion state, one section of the anchor chain connecting the winch and the fixed pulley is in a loose state, so that the service life of the winch is prevented from being influenced by the excessive work. In addition, the floating frame-air pump buoyancy adjusting device can provide necessary buoyancy during normal work, gradually loses buoyancy in the submerging process, completes submerging work by matching with the winch-anchor chain fixing device, and gradually restores buoyancy in the restoring process, so that the aquaculture net cage is restored to a working state. The tension of the two-section anchor chain is controlled to be in a reasonable interval through buoyancy adjustment, and the purposes of stable submergence and recovery and protection of the two-section anchor chain are achieved.
The technical scheme of the invention is as follows:
an autonomous submerging system for a culture net cage comprises a winch-anchor chain fixing device and a floating frame-air pump buoyancy adjusting device. The winch-anchor chain fixing device consists of a winch, a floating winch base, three lockable pulleys, a fixed pulley locking device, a slideway, a first section of anchor chain, a second section of anchor chain, an anchor and a floating frame. The floating frame-air pump buoyancy regulating device consists of floating frame, automatic control valve, powerful pump and compressed air tank.
The winch is fixedly connected with the floating winch base, the floating winch base is hinged with one section of the slideway, the other end of the slideway is hinged with the floating frame, the winch is connected with the fixed pulley through one section of the anchor chain, the other section of the anchor chain moves in the slideway, the fixed pulley is connected with the anchor through two sections of the pulleys, the fixed pulley locking device serves as a lockable pulley auxiliary device and is located at the same position with the fixed pulley, and the other end of the anchor is fixedly connected with the ground.
The floating frame is provided with an automatic control valve, a powerful pump and a compressed air tank. When the automatic control valve is closed, the floating frame is in a watertight state, when the automatic control valve is opened, the floating frame is connected with water, when the internal pressure of the floating frame is lower than the water pressure, the water is poured into the floating frame, and when the internal pressure of the floating frame is increased, the water is discharged from the valve.
The powerful pump is matched with the compressed air pipe. The powerful pump can pump compressed air into the floating frame, promotes the inside pressure of floating frame. The high-pressure air tank can be supplemented with high-pressure air at the water surface.
The slide way is provided with an escalator for people to pass through.
An autonomous submerging system of a culture net cage is composed of a winch 1, a floating winch base 2, three lockable pulleys 3, a fixed pulley locking device 4, a slideway 5, a first section anchor chain 6, a second section anchor chain 7, anchors 8 and a floating frame 9. The winch 1 is fixedly connected with a floating winch base 2, the floating winch base 2 is hinged with one end of a slideway 5, the other end of the slideway 5 is hinged with a floating frame 9, the winch 1 is connected with a fixed pulley 3 through a section of anchor chain 6, the section of anchor chain 6 moves in the slideway 5, the fixed pulley 3 is connected with an anchor 8 through a section of anchor chain 7, a fixed pulley locking device 4 is used as a lockable pulley auxiliary device and is positioned at the same position with the fixed pulley 3, and the other end of the anchor 8 is fixedly connected with the ground; an automatic control valve 10 is arranged on the floating frame 9, a powerful pump 11 is arranged on the floating frame, and a compressed air tank 12 is arranged at the other end of the powerful pump 11; the slideway is provided with an escalator for people to pass through.
When the aquaculture net cage needs to descend and avoid danger in the face of complex sea conditions, the shore-based control room sends an descent command, and the descent system starts to work. The fixed pulley locking device is unlocked, and the winch tightens one section of anchor chain to drive the fixed pulley to rotate and tighten the two sections of anchor chains. Meanwhile, the automatic control valve is opened, the air pressure bottom and the water pressure in the floating frame lose buoyancy, and the equipment begins to descend.
When the floating frame is completely immersed in water, the automatic control valve is closed. At the moment, the floating frame loses most buoyancy, and the residual buoyancy is the pretightening force of the two-section anchor chain to control the horizontal displacement of the aquaculture net cage.
After the winch is descended to a proper position, the winch stops working, and the fixed pulley locking device locks the fixed pulley. At this time, one section of the anchor chain is loosened, and the winch is not stressed. The two sections of anchor chains are only subjected to preset pretightening force.
And when the complex sea condition disappears and the net cage needs to be restored to a normal state, the shore-based control room sends a restoration instruction. The automatic control valve is opened, the air in the compressed air pipe is pumped into the floating frame by the high-pressure pump, the pressure inside the floating frame is higher than the water pressure, the ballast water is discharged, and the floating frame restores the buoyancy. Meanwhile, the fixed pulley locking device opens the fixed pulley, and the winch works in the reverse direction. The breeding net cage returns to the working state under the action of buoyancy, and the hoist controls the returning rhythm to ensure the stable returning of the breeding device.
When the breeding equipment returns to the working state, the winch stops working, and the fixed pulley locking device locks the fixed pulley. After the recovery state is stable, the air is pumped into the air compression tank by the high-pressure air pump line, and the initial air pressure of the air pipe is recovered.
After one or more times of descending work, the worker performs normal maintenance work through the escalator.
At present, the submergence and recovery operation of the traditional submergence-submersible aquaculture net cage is mainly completed by professional divers, the submergence operation of the system is not completed by the professional divers, and the submergence and recovery operation can be realized by the remote control of a shore-based command center. No matter in a working state or a submergence state, the anchor chain can be always in a tensioning state through the winch-anchor chain fixing device, the position of the culture equipment is effectively controlled, large displacement cannot be generated in the horizontal direction, and the condition that the net cage is collided due to overlarge displacement in the horizontal direction during submergence is avoided. In addition, the buoyancy adjusting device of the floating frame and the air pump can actively adjust the buoyancy, and the tension of the anchor chain in a submerging state is effectively reduced. In addition, through the design of two sections of anchor chains, the winch is stressed only in the process of submergence and restoration, the working strength of a stress component of the autonomous submergence and descent system is effectively reduced, and the service life of the submergence and descent system is prolonged.
