DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The purpose of the present invention is to provide a raft-type aquaculture equipment and its use method to solve the problems existing in the prior art, with a simple structure and being safe and reliable.

[0025] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] The present invention provides a raft-type aquaculture equipment, as Figures 1 to 3 shown, including a raft frame 101 for hanging culture, a ballast tank 200 fixedly arranged on the raft frame 101, and a mooring system. A buoy 103 is fixedly arranged below the raft frame 101. Preferably, a plurality of buoys 103 are provided and evenly distributed around the bottom of the raft frame 101; preferably, a plurality of ballast tanks 200 are provided and evenly distributed around the bottom of the raft frame 101. A water injection pipe 201, a drain pipe 202, and an air outlet pipe 203 are connected and communicated with the ballast tank 200. A switch valve is arranged on the water injection pipe 201, and a check valve and a drainage pump are arranged on the drain pipe 202. The check valve can adopt an existing device to prevent seawater from flowing back during drainage. A float ball is fixedly arranged at one end of the air outlet pipe 203 away from the ballast tank 200. The float ball can float on the water surface to ensure that the exhaust port of the air outlet pipe 203 is above the water surface. When no ballast water is injected, the ballast tank 200 provides buoyancy for the raft frame 101 like the buoy 103. After injecting ballast water, the raft frame 101 can sink to the required depth; the mooring system includes an anchor 301, a mooring cable 302, and a tensioning mechanism 303 fixedly arranged on the raft frame 101. One end of the mooring cable 302 is fixedly connected to the anchor 301. After the anchor 301 is connected to the mooring cable 302 and put into the water, the aquaculture equipment can be fixed at a fixed position on the seabed. The other end is wound around the tensioning mechanism 303, and the tensioning mechanism 303 can take in and release and fix the mooring cable 302.

[0027] The research results show that when the aquaculture equipment descends to a certain depth below the water surface, the force on the aquaculture equipment and the tension of the anchor rope decrease significantly; and the greater the wave height and the greater the period, the more obvious the decrease. Therefore, when the offshore raft aquaculture equipment faces bad weather, it can dive to a certain depth to effectively reduce the force on the equipment for avoidance; the raft aquaculture equipment provided by the present invention can realize the floating or sinking of the aquaculture equipment for risk avoidance by performing water inlet and drainage operations on the ballast tank 200 and cooperating with the adjustment of the tensioning mechanism 303. The device has a simple structure, is convenient for installation and replacement, can reduce the manual installation cost, the cost investment of the aquaculture equipment is relatively low, and it is safe and reliable to use, and is more convenient for rapid popularization among farmers.

[0028] In some embodiments, the raft frame 101 is formed by connecting multiple raft poles in a crisscross manner. The raft poles can be used to hang oysters horizontally. A floating cylinder 103 is fixed below the raft poles to provide buoyancy for the aquaculture equipment. The raft frame 101, the floating cylinder 103, and the ballast tank 200 are preferably made of HDPE environmental protection materials. The entire aquaculture equipment is environmentally friendly, low-pollution, and easy to produce standardized products.

[0029] In some embodiments, the raft poles are connected in a traditional manner, that is, they are connected and fixed through fasteners 102 formed by polymer injection molding.

[0030] In some embodiments, a plurality of mooring systems are provided and are evenly distributed around the raft frame 101. The tensioning mechanism 303 includes a cable winch barrel rotatably connected to the raft frame 101 and a ratchet wheel 402 located on one side of the cable winch barrel and fixedly connected to the cable winch barrel coaxially. A rotating handle 401 is provided on the side of the ratchet wheel 402 away from the cable winch barrel. A pawl 403 is movably arranged on the raft frame 101. The pawl 403 can be clamped on the ratchet wheel 402. The pawl 403 is preferably rotatably connected to the raft frame 101. A torsion spring is provided at the connection between the pawl 403 and the raft frame 101. Under the action of the torsion spring, the pawl 403 can be pressed against the ratchet wheel 402, so that the ratchet wheel 402 can only rotate in one direction. After manually lifting the pawl 403, the ratchet wheel 402 can rotate in both directions.

[0031] The present invention also provides a method for using a raft aquaculture equipment, which is applied to the raft aquaculture equipment. After installing the floating cylinder 103 and a certain number of ballast tanks 200 below the raft frame 101, a floating raft is formed. The floating raft is transported to a designated position in the offshore aquaculture area and connected to the mooring system that has been in place. The tensioning mechanism 303 is fixedly installed at a designated position on the floating raft. During operation, the process of the aquaculture equipment sinking for risk avoidance includes the following steps:

[0032] Step 1: The aquaculture personnel take a boat to the aquaculture area, open the water inlet of the ballast tank 200, and the floating raft loses buoyancy and sinks.

[0033] Step 2: The aquaculture personnel dive into the water and manually adjust the tensioning mechanism 303, which is a ratchet 402 mechanism that can rotate in one direction to tension the slack mooring cable 302 to ensure that the aquaculture equipment does not have a large displacement.

[0034] In some embodiments, it further includes Step 3: The floating ball can be used as a marker to facilitate quickly finding the location of the aquaculture equipment after the end of the disastrous weather.

[0035] The process of the aquaculture equipment floating up includes the following steps:

[0036] Step 1: The aquaculture personnel take a boat to the aquaculture area, find the area marked by the floating ball, dive into the water to close the water inlet of the ballast tank 200, and connect the drain pipe 202 to the connecting pipe of the on-board drainage pump to perform the drainage operation of the ballast tank 200.

[0037] Step 2: At the same time, the aquaculture personnel dive into the water, release the pawl 403 of the tensioning structure, and reverse-rotate the slack mooring cable 302 to ensure the smooth floating up of the aquaculture equipment.

[0038] Step 3: After surfacing, the aquaculture personnel appropriately adjust the tensioning mechanism 303 to ensure that each mooring cable 302 of the aquaculture equipment has a certain pre-tension, thereby restricting the movement distance of the floating raft.

[0039] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
