Description

Unmanned feed supply ship for fish farms {UNMANNED FEED SUPPLYING SHIP}

The present invention relates to an unmanned feed supply ship for fish farms. More specifically, the present invention relates to an unmanned feed supply ship for fish farms, and more specifically, allows workers to distribute feed while driving around the fish farm by manipulating a control device, thereby increasing the convenience and efficiency of feed supply as well as improving the convenience and efficiency of feed supply. This relates to an unmanned feed supply ship for fish farms that can increase the amount of dissolved oxygen in a fish farm by generating bubbles and blowing them out while driving.

In general, in addition to land-based aquaculture facilities that cultivate various types of fish at high density by installing aquaculture tanks inside buildings, cage fish are moored with scaffolding structures to a certain extent in water areas such as lakes, rivers, and the sea. In cage aquaculture facilities where various types of fish are cultivated at high density, the most important aspect of farm management is the periodic supply of food necessary for fish growth, that is, feed, according to the required time period.

Previously, manual work was done in which the farm manager went directly to the site and scooped up the feed stored in the feed storage bin with a bucket, etc., and scattered the feed. However, this caused labor waste and economic burden, so recently automated feed supply devices have been used. There is a trend toward replacing field managers.

A typical conventional feed supply device installs a rotary valve at the bottom outlet of the feed storage hopper as a gate to discharge and block the feed, and uses a blower to transfer the feed to the cage net or aquaculture tank. A blower-type supply device (refer to prior art literature) that uses a blower (blower) and a screw-type supply device that both inputs and transports feed by directly connecting a screw conveyor to the bottom outlet of the feed storage bin.

However, since conventional feed supply devices were usually used one at a time for each cage net or aquaculture tank, there was a problem of excessive costs due to installation and maintenance of feed supply devices in large-scale fish farms, and it was difficult to prevent this. For this reason, when it is desired to feed multiple aquaculture tanks or cage water with a single feed supply device, a scaffolding structure for cage water in a relatively narrow space or a manifold containing a valve mechanism across the bottom of the farm is used. Because an additional feed distribution device in the form of a manifold (管: Manifold) had to be installed, not only was it difficult to efficiently utilize space in the fish farm, but there was also a problem in that setting up the feed distribution device and controlling the feed supply route were also very difficult.

As a background technology of the present invention, a feed supply device for a feed supply ship in a fish farm is disclosed in Republic of Korea Patent Publication No. 10-2022-0011443.

The present invention was created in consideration of the above-mentioned situation, and the purpose of the present invention is to increase the convenience and efficiency of feed supply by scattering feed while the operator drives the fish farm by operating the control device, and to prevent bubbles from forming when the hull is driven. The purpose is to provide an unmanned feed supply ship for fish farms that can increase the amount of dissolved oxygen in the fish farm by generating and spewing out.

Feed injection unit 300 for discharging; It is characterized in that it is configured to include; a bubble ejection device 500 installed on the lower side of the stern of the hull 100 to eject fine bubbles to the rear of the hull 100.

In addition, it is configured to further include an air blowing device 400 that blows air into the inside of the extension pipe 210 while mounted on the feed supply tank 200, and the bubble blowing device 500 A submersible pump 510 installed in the mounting hole 511 formed on the lower side of the stern of the hull 100, a jet nozzle unit 520 that ejects fine bubbles backward while connected to the submersible pump 510, and , One longitudinal side is connected to the blowing nozzle unit 520, and the other longitudinal side extends to the upper side of the hull 100, and includes an external air inlet pipe 550 that allows external air to flow in.

According to the present invention, as the hull travels through the fish farm and supplies feed by scattering it, work convenience and efficiency for feed supply are improved, and the effect of increasing the amount of dissolved oxygen in the fish farm can be obtained due to the generation of bubbles when the hull runs.

It may be rotated by the rotation motor 127 to adjust the traveling direction of the hull.

That is, when the propeller 121 is driven, the hull 100 travels, and in such a state, when a change in direction of the hull 100 is necessary, when the rotation motor 127 is driven, the rotation motor As the rudder connected to the sphere 127 rotates, the other rudder also rotates in the same direction by the joint connecting bar 126. Here, a guard frame 130 may be installed on the hull 100 to protect the propeller 121.

In addition, the feed supply tank 200 is installed on the upper side of the hull 100 and is filled with aquaculture feed inside, and an extension pipe 210 extending in the bow direction of the hull 100 is installed.

Here, an opening and closing cover 220 is installed on the upper side of the feed supply tank 200 to open and close the inside, and a rotating stirring wing (not shown) is installed inside the feed supply tank 200 as necessary. This will prevent the feed filled inside the feed supply tank 200 from clumping together or being concentrated on one side of the inside of the tank.
