Description

Technical Field

[0001] This invention relates to the field of oyster farming technology, and more specifically to a wind and wave resistant oyster raft farming device and method. Background Technology

[0002] The artificial cultivation of Okinawa oysters has a history of more than 300 years in my country. In the early stages, the main cultivation methods were to use stones, tiles, ceramics, and plastic molds to collect and cultivate oysters on the tidal flats (in the near sea). Later, bamboo, wood, and cement products were used to collect and cultivate oysters, which greatly increased the yield.

[0003] Oyster farming has now evolved to utilize floating rafts for deep-water cultivation. Due to the improved farming environment, diseases are effectively controlled, the farming cycle is shortened, costs are reduced, and farming efficiency is improved.

[0004] Although floating raft aquaculture has helped control pests and diseases to some extent, the oyster farming facilities float on the sea surface during the process. When typhoons come, the strong winds and waves directly impact the floating rafts, making them extremely vulnerable to damage.

[0005] Therefore, it is an urgent problem for those skilled in the art to develop an oyster raft aquaculture device and method that can withstand wind and waves and has strong structural stability. Summary of the Invention

[0006] In view of this, the present invention provides an oyster raft aquaculture device and method that can resist wind and waves and has strong structural stability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wave-resistant oyster raft aquaculture device, comprising:

[0009] floating tank,

[0010] An aquaculture frame, comprising: an aquaculture plate, a fixing plate, and a connecting rod; the aquaculture plate is disposed at the bottom of the floating box; the fixing plate is disposed below the aquaculture plate; and the connecting rod is disposed between the aquaculture plate and the fixing plate.

[0011] The suspension ropes are provided in multiples and are evenly distributed between the breeding board and the fixing plate. The top of the suspension rope is connected to the breeding board and the bottom is connected to the fixing plate.

[0012] A wave deflector is located on the side of the aquaculture rack. One end of the wave deflector is hinged to the side of the fixed plate, and the other end is connected to a winch. The winch is connected to the aquaculture plate and drives the wave deflector to rotate up and down.

[0013] An anchor chain, one end of which is connected to the fixing plate and the other end is fixed to the seabed.

[0014] The beneficial effects of adopting the above technical solution are that the pontoon in this invention is an integrated type, which can enhance the stability of the structure, and the wave deflector can protect the oysters and resist the impact of wind and waves.

[0015] Preferably, the interior of the pontoon is hollow, and a water inlet is provided on the surface of the pontoon, at which a water pump is installed. The water pump can flush water into or drain water from the pontoon to increase its buoyancy; and the water volume in the pontoon can be adjusted according to the depth of the pontoon in the water.

[0016] Preferably, the float has a first hollow groove in the middle. The first hollow groove facilitates the removal of the sling with the oyster attached.

[0017] Preferably, multiple pontoons are arranged side by side. Each pontoon has a hook-shaped insertion slot on one side and a hook-shaped insertion block on the opposite side. The insertion slots and insertion blocks of adjacent pontoons are inserted into each other and secured with screws. The insertion of the insertion blocks into the insertion slots facilitates the connection of the pontoons, and the screw securing improves the stability of the connected pontoons.

[0018] Preferably, the surface of the aquaculture board is provided with a second hollow groove, and multiple aquaculture rods are arranged side by side in the second hollow groove, with the top of the suspension rope connected to the aquaculture rods.

[0019] Preferably, a limiting groove is formed on the surface of the aquaculture rod, and the suspension rope is placed in the limiting groove. The limiting groove can limit the position of the suspension rope.

[0020] Preferably, an iron block is provided at the bottom of the suspension rope, and a groove is formed on the top of the fixing plate at a position corresponding to the suspension rope. An electromagnet is provided at the bottom of the groove; the iron block is inserted into the groove. The iron block can increase the counterweight of the suspension rope, and at the same time, through the attraction of the electromagnet, the suspension rope can be stably connected between the breeding plate and the fixing plate, and it is also convenient to remove the suspension rope.

[0021] Preferably, the bottom of the anchor chain is provided with an adsorption cylinder, and the top of the anchor chain is connected to a motor, which is embedded inside the fixing plate.

[0022] Preferably, the surface of the wave deflector is provided with mesh holes.

[0023] Preferably, the float is equipped with a temperature sensor. The temperature sensor can detect the temperature of the water.

[0025] S1. First, install and connect multiple floating boxes. After the connection is completed, put the floating boxes and aquaculture racks into the water together.

[0026] S2, the adsorption tube is pre-buried in the seabed, and then the floating box and aquaculture rack are moved to the designated position by the motor retracting the anchor chain;

[0027] S3, the growth temperature of oysters is 6℃-32℃. Based on the temperature detected by the temperature sensor, the height of the oysters in the water is adjusted so that they can grow at the set temperature.

[0028] S4. When the wind speed on the sea surface reaches level 12-13, the pontoon will be lowered to a position 2.5-2.7m above the sea surface; when the wind speed on the sea surface reaches level 14-15, the pontoon will be lowered to a position 4.5-4.7m above the sea surface; when the wind speed on the sea surface is ≥ level 16, the pontoon will be lowered to a position 5.7-5.7m above the sea surface.

[0029] S5, when encountering strong winds, flip the wave deflector to the side of the aquaculture rack to block the wind and waves.

[0030] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an oyster raft aquaculture device and method resistant to wind and waves, the beneficial effects of which are:

[0031] (1) In this invention, the floating box is an integral piece, and the floating box and the aquaculture rack are rigidly connected. Its structure is highly stable and can effectively resist wind and waves.

[0032] (2) The wave deflector can protect the oysters, and by moving the depth of the pontoon, the impact of wind and waves can be effectively reduced. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] This invention discloses a wind and wave resistant oyster raft aquaculture device, comprising:

[0047] Floating tank 1,

[0048] The aquaculture frame 2 includes: an aquaculture plate 21, a fixing plate 22, and a connecting rod 23; the aquaculture plate 21 is located at the bottom of the floating box 1; the fixing plate 22 is located below the aquaculture plate 21; and the connecting rod 23 is located between the aquaculture plate 21 and the fixing plate 22.

[0049] Multiple hanging ropes 3 are provided and evenly distributed between the breeding board 21 and the fixing plate 22. The top of the hanging rope 3 is connected to the breeding board 21 and the bottom is connected to the fixing plate 22.
