The practical use of the trigger float-over discharge device in this embodiment is as follows,
firstly, the triggered upper floating releasing type releasing appliance is transported to a releasing sea area (the depth of the releasing sea area is generally 30-100 meters);
secondly, placing the snail seeds in the breeding box on a transport ship, wherein in the embodiment, the total weight of the snail seeds placed in the breeding box is 50-70 kg, specifically, the snail seeds are placed in the breeding box through the placing opening, and then the cover plate is connected with the breeding box through a binding belt so as to cover the placing opening.
And thirdly, the triggered floating releasing device is thrown into the seawater and is settled to the seabed.
In actual operation, the triggered floating and releasing type releasing device can be directly thrown into seawater and settled to the seabed, and specifically, in the process of throwing the triggered floating and releasing type releasing device into the seawater, the culture box body is manually pulled upwards along the vertical supporting sleeve by manpower, so that the top surface of the culture box body is abutted against the lower end of the vertical supporting sleeve; keeping the top surface of the breeding box body against the lower end of the vertical supporting sleeve, completely putting the triggered floating and releasing type releasing device into seawater, moving the breeding box body upwards along the vertical supporting sleeve under the buoyancy action of the floating block, and making the top surface of the breeding box body against the lower end of the vertical supporting sleeve; then, releasing and triggering the upper floating discharge type releasing device to enable the upper floating discharge type releasing device to be settled to the seabed;
in addition, for convenience of operation, the vertical guide rod and the vertical support sleeve on the breeding box body are prevented from being separated, and the sliding balancing weight and the transverse guide rod are prevented from being separated in the process of throwing the trigger floating releasing type releasing device into sea water and the process of sinking the trigger floating releasing type releasing device to the seabed; before an operator puts the triggering floating-up releasing type releasing device into seawater, the vertical guide rod can be bonded on the vertical support sleeve and the sliding balancing weight can be bonded on the transverse guide rod through temporary bonding hydrolysis glue (namely glue which can be automatically dissolved in the water again after solidification, such as water-soluble UV glue); then, the triggering floating releasing type releasing device is thrown into the sea water and settled to the seabed.
As shown in fig. 1, after the upper floating discharge type releasing device is triggered to settle to the seabed, the upper floating discharge type releasing device is supported on the seabed through the bottom surface of the base, and at the moment, the top surface of the breeding box is kept to be propped against the lower end of the vertical supporting sleeve under the buoyancy action of the floating block by the breeding box;
after that, the snail seeds are attached to and grow in the breeding box body (if the vertical guide rod is bonded on the vertical support sleeve and the sliding balancing weight block is bonded on the horizontal guide rod through the temporary bonding hydrolysis glue, in the process, the temporary bonding hydrolysis glue is gradually hydrolyzed and melted, so that the vertical guide rod can slide along the vertical support sleeve again, and the sliding balancing weight block can slide along the horizontal guide rod again), and gradually grow up along with the snail seeds in the breeding box body (generally for 2-4 weeks), as shown in fig. 3, when the sum of the gravity of the snail seeds in the breeding box body and the gravity of the falling-off floating-type snail seed temporary breeding device is greater than the buoyancy of the floating block, the breeding box body sinks along the vertical support sleeve. After vertical guide arm and vertical support cover separation, the breed box will slide the balancing weight and take place to rotate (the relative both sides that the balancing weight and the kicking block were located the breed box) under the combined action of kicking block, the speed of sinking of one side of the breed box at slip balancing weight place will be greater than the speed of sinking of one side of the breed box at kicking block place, so that breed the box and rotate, one side of the breed box at messenger's slip balancing weight place distributes down, one side of the breed box at kicking block place distributes up, so, after one side of the breed box at slip balancing weight place distributes down, the slip balancing weight will follow horizontal guide arm landing and subside to the seabed. After the sliding balancing weight is separated from the transverse guide rod, the breeding box body floats upwards under the buoyancy action of the floating block. In the floating process of the breeding box body and before the connecting rope is tightened, because the snail seeds are attached to the inner side surface of the breeding box body, the scraper blade and the sealing and shielding plate are blocked and cannot move downwards, the breeding box body, the scraper blade, the sealing and shielding plate and the snail seeds in the breeding box body float together; as shown in fig. 4, when the connecting rope is in a stretched state, the scraper and the shielding plate stop floating, the breeding box body continues floating under the action of the floating block, so that the snail seeds attached to the inner side surface of the breeding box body are scraped off by the scraper and fall down from the snail discharge port, namely the snail seeds fall down at a height of about 20 meters away from the seabed, and thus, the problem that the survival rate of the snail seeds is reduced because the snail seeds are sown on the sea surface in the prior art and are easily taken away by ocean currents due to the fact that the ocean currents close to the sea surface are large and distributed to an area of the seabed which is not suitable for the adhesion and growth of the snail seeds is effectively solved; and the snail seeds can be diffused and distributed to the seabed of the designated release sea area, so that the recovery of snail populations is facilitated. In addition, the snail seeds can be protected by the culture box within 2-4 weeks after being thrown to the seabed.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
