That is, it will be understood by those skilled in the art that the buoyancy providing unit 110 may be configured such that three or more buoyancy members 111 may be properly connected by a plurality of supports 119 to perform the same function. It also falls within the scope of the present invention.

The positive network 120 is fixed on the support 119 installed on the upper portion of the body 112 of the plurality of supports (119). Positive network 120 is a low-height rectangular shape made of a mesh (mesh) member, the oyster plaque is accommodated therein. Mesh size of the positive network 120 may be appropriately adjusted according to the growth of the oyster chip. In other words, the mesh size of the positive network 120 may be appropriately selected within a diagonal length of 1 to 50mm according to the size of the oyster chip.

The air supply unit 130 supplies air to the accommodation space 112a inside the body 112 as necessary, thereby increasing buoyancy of the body 112. The air supply unit 130 includes an air pump 131 and a connection hose 132. Although not shown in detail, the air pump 131 may be properly installed outside the sea water. In this embodiment, the air pump 131 is described as being provided with one corresponding to each of the two buoyancy member 110, but, alternatively, only one air pump 131 may be used. The air pump 131 may be automatically controlled by a controller (not shown) or manually by an administrator. In the present embodiment, the air pump 131 is described as being driven by external power, but alternatively, a manpower operated by a manager may be used. The connection hose 132 connects between the air pump 131 and the inlet pipe 113 provided in the buoyancy member 110. The connection hose 132 is connected with the middle portion of the inlet pipe 113.

The drift prevention means 140 is a rope fixed to both longitudinal ends of each body 112 of the two buoyancy members 111, respectively. Each rope is secured to the bottom of the seawater, preventing the marine oyster farming device 100 from drifting and being swept away by waves or waves.

The settlement limiting means 150 includes a float 151 and an extension 152 connected to the float 151. The body 151 is connected to both longitudinal ends of each body 112 by the extension part 152, respectively. The floating body 151 provides buoyancy so that the marine oyster farming device 100 does not sink below a predetermined depth. The extension 152 connects the body 151 and the body 112. In this embodiment, the extension portion 152 is described as a rope. Alternatively, the extension portion 152 may have a pillar shape extending upwardly. The length of the extension 152 determines the depth limit for settlement of the marine oyster farming device 100. The floating body 151 also functions as a buoy to inform the position of the positive network 120 when it is located below the sea level.

The controller (not shown) is connected to the air discharge valve 115 and the air pump 131 by wire or wirelessly to control the operation. The controller (not shown) outputs a control signal for opening / closing the air discharge valve 115 and operating the air pump 131, and may include a timer to automatically output the control signal at a predetermined time.

The power supply unit (not shown) provides power for the operation of the air discharge valve 115, the air pump 131, and the control unit (not shown). As a power supply unit (not shown), various methods of supplying power may be used. In this embodiment, solar power generation will be described.

The operation of the above embodiment will now be described in detail with reference to the drawings.

2 shows a submerged state in which the positive network 120 is immersed in the seawater to an appropriate depth. In this state, the receiving space 112a in the body 112 of the buoyancy member 111 is filled with seawater, and the seawater oyster farming device 100 is forced to sink downward. If the sinking force is insufficient due to buoyancy, additional load may be added. And, at this time, while the seawater oyster culture apparatus 100 is prevented from sinking deeper than necessary by the settlement limiting means 150, the exact position of the sunken seawater oyster culture apparatus 100 can be grasped. After the dive state shown in FIG. 2 lasts for a set time, the controller (not shown) outputs a control signal to the air pump 131 to operate the air pump 131, and also sends a control signal to the on / off valve 115. It outputs and closes the shut-off valve 115. Air is supplied by the air pump 131 to the passage 113a in the inlet pipe 113 through the connecting hose 132, and the air passes through the passage 113a to the accommodation space 112a inside the body 112. Supplied. As the accommodation space 112a is filled with air, the buoyancy of the buoyancy member 111 gradually increases. When the amount of air required for the rise of the seawater oyster farming device 100 is filled in the receiving space 112a, the seawater oyster farming device 100 starts to rise up and eventually, as shown in FIG. 120) is injured above sea level. After the floating state shown in FIG. 3 is maintained for a set time, the controller (not shown) outputs a control signal to the open / close valve 115 to open the closed open / close valve 115. Accordingly, the air filled in the receiving space 112a in the body 112 is discharged to the outside through the discharge pipe 114, and at the same time seawater is supplied to the receiving space 112a through the inlet pipe 113 to receive the receiving space ( 112a) will be filled with seawater. As the receiving space 112a is filled with seawater, the buoyancy of the buoyancy member 111 gradually decreases, so that the seawater oyster farming device 100 does not sink below the water so that the positive network 120 is submerged. Will be placed in the same dive. By repeating the above-described diving and floating conditions periodically, it is exposed to strong sun in summer and bitter cold wind in winter, so that it is possible to nourish oysters with good nutritional quality. The marine oyster culture apparatus 100 is to maintain a fixed position by the drift prevention means 140, which is a rope fixed to the floor.

In the above embodiment, the timing of the ups and downs of the marine oyster farming apparatus 100 has been described as being automatically controlled by a controller (not shown). However, the ups and downs timing may be appropriately manually adjusted by an administrator.
