The bottom hung of described net cage 2 has weight 1.
The process of bascule of the present invention is as follows:
1, sink:
As the user from sending the sinking instruction by SMS on the bank, the marine control system be arranged on net cage receives instruction and moves the sinking program by wireless network, breather valve 10 in four float component is opened, like this, under the effect of water pump (water pump is parts common in prior art, and its mounting means is also very common, not shown), floating drum 6 is by water inlet 3 water inlets of lower end, and net cage 2 starts to sink.
In the process of sinking, when net cage 2 balance, the conducting liquid 15 in balance pipe 11 as shown in Figure 3.When net cage 2 is uneven, conducting liquid 15 in place's bend pipe 12 on the low side as shown in Figure 4, now, two terminals 13 in place on the low side bend pipe are connected by conducting liquid 15, after experiencing electric current, sensor 14 outside balance pipe 11 just information is passed to marine control system, marine control system is sent the correction order, closes the water inlet 3 of the floating drum 6 of this pipe bent position.As time goes on, that lateral balance pipe 11 on the low side will be no longer on the low side because of not intaking.In like manner, when higher the time, will flow to place on the low side by balance pipe 11 interior conducting liquids 15, thereby expose two terminals 13 and disconnecting circuit, now sensor also can send this information to marine control system, and marine control system is sent the correction order again, opens the water inlet of the floating drum 6 of this pipe bent position, like this, a higher side will slowly be avaled.So just guaranteed the balance of net cage in the sinking process.
When the water surface curve in floating drum 6 arrives upper water level 7, the sensor at this place sends signal to marine control system, and marine control system is given an order and closed breather valve 10.Because total gravity of the water in net cage 2, weight and floating drum 6 is greater than the buoyancy of seawater, net cage 2 still sinks until the preset depth of water, now, the weight seabed interaction, total gravity will be less than the buoyancy of seawater, and net cage will float over preset depth of water place.Now return information is given user on the bank, informs that user's net cage has sunk to the preset depth of water, waits for user's floating order.
2, floating:
When the user from by SMS, send on the bank the floating instruction, the marine control system be arranged on net cage receives instruction and moves the floating program by wireless network, the breather valve 10 of four floating drums 6 is all closed, start charge valve 8 simultaneously and start to the interior inflation of floating drum 6, when the gas in floating drum 6 reaches certain value, water inlet 3 starts outside draining.Along with the seawater in floating drum 6 is discharged gradually, net cage 2 starts floating.
Net cage floats up to sea, and when the water level in floating drum 6 arrives lower water level 4, the sensor at this place sends signal to marine control system, and marine control system is given an order and closed charge valve 8, and now net cage returns to the poised state of front floating on water.Now marine control system return information is given user on the bank, informs that user's net cage has completed floating, and starts the gas compensation program, gives in compressed air cylinder 5 and carries out gas make-up.
At net cage in floating during state, for avoiding the impact because of factors such as water, air valve are slowly revealed, the infiltrations of floating drum weld seam, cause net cage to issue and give birth to heavy phenomenon in the situation of no user sinking instruction, in system, the lower level sensor of floating drum detects the position of the water surface automatically, if water level is during higher than lower water level 4, marine control system automatically performs the floating program, in floating drum, inflates, and makes net cage be restored to equilbrium position.
The electrical schematic diagram of the automatic sedimentation system of Deep sea net cage of the present invention as shown in Figure 5 is known, and SB1 controls the switch of water pump, and SW1 is location switch, and KM1 is for controlling total valve, and KM2, KM3, KM4 and KM5 are respectively the breather valves of four floating drums.
When net cage sinks, SB1 disconnects, and KM1 connects, and location switch SW1 connects, and KM2, KM3, KM4 and KM5 all connect.At this moment in four floating drums, intake, net cage starts to sink.While an on the low side place floating drum occurring when net cage sinks, bascule just there will be the situation of Fig. 4, and sensor 14 passes to marine control system to information, and marine control system will disconnect the breather valve switch of controlling this floating drum.As time goes on, originally on the low side will perk, sensor 14 can pass to marine control system to information again, marine control system will be connected the breather valve switch of controlling this floating drum, thereby to water filling in floating drum.During to the preset depth of water, by the water level detected in floating drum, whether arrive upper water level when normal, the sensor by upper water level place sends information, is disconnected to bit switch SW1 and four breather valve K switch M2, KM3, KM4 and KM5.
When net cage floats, connect SB1, booster air pump, be switched to bit switch SW1, at this moment by charge valve to aeration of float, net cage will slowly float.When floating process appearance imbalance, the charge valve of the floating drum at a higher place is closed automatically, stops inflation, at leisure, the floating drum at a higher place will sink, and at this moment charge valve will automatically be opened and continue inflation, until net cage climbs up on top of the water above, at this moment the water level in floating drum will reach lower water level.Now, start the gas compensation program, prevent that net cage from sinking because of gas leakage.
