The drainage port is provided with a drainage network to prevent the spoilage of the aquaculture product from being lost due to drainage of the breeding water, The present invention relates to a drainage device of a multi-layer aquarium that can be easily assembled and disassembled to save working time and installation cost.

With the recent development of aquaculture technology, the technology to cultivate the target organisms in the aquarium instead of the sea has been established, and the concept of the concept of cultivating a variety of seafood in each floor, .

In general, aquaculture by seawater is largely divided into aquaculture and marine cage culture. Onshore aquaculture is a method of transplanting and cultivating a target organism into a terrestrial tank that can artificially control the habitat environment from the sea, , Marine cage is a way to put a net in the wide space of the sea and to confine the creature.

Recently, when the fishermen are plowed from the sea to the cage farms and cultured from the time of drowning, the time for exposing them to the risk of natural disasters becomes longer, and the yield is lowered. In order to improve these problems and improve the yield, It is increasing trend to cultivate fish and shellfish at high density in aquariums, and to cultivate them until they reach a certain value in caged fish farms.

Thus, in order to cultivate marine animals and plants at high density, aquaculture tank equipped with various facilities such as breeding water supply and drainage facilities, purification facilities or oxygen supply facilities in order to create the optimum environment for the growth of marine animals The environment protects aquatic organisms and forms a suitable breeding environment for aquaculture to a certain size.

However, the on-shore water tank system is provided with a drainage facility capable of removing pollutants periodically so that a small amount of water is continuously supplied to the inside of the water tank through the water supply pipe, and the water level in the water tank is maintained at a proper level by the water level maintenance pipe, There is a problem that the pollutants settled in the bottom of the water tank continue to accumulate in the water tank because the remaining water does not reach the small amount of continuous water. As a result, contaminants such as feed residue and excrement are deposited on the bottom of the water tank, and the stored water in the water tank is contaminated.

As a method to prevent this, a large amount of water supply and drainage can be continuously performed in the water tank, so that the pollutant is not accumulated but the water can be continuously discharged. However, another problem arises that the continuous water supply is costly. In addition, when the water level maintenance tube is removed from the discharge port of the drain pipe, a large amount of water is drained instantaneously by the water level, and the water is rapidly introduced into the drainage port and vortices are formed around the water discharge pipe. There was a problem that it swept and drained water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of a multi-layered aquarium drain according to the present invention will be made in detail with reference to the accompanying drawings and accompanying drawings.

1 is a photograph showing a drain hole of a conventional aquaculture tank. A drainage hole is formed in either one of the both ends of the water tank body, and a water level control pipe is installed in the drainage port, and when the water exceeding the height of the water level control pipe is supplied, the water is drained beyond the water level control pipe. If the water level control pipe is installed inside the water tank, it is not easy to clean the floor water in the aquaculture tank. Therefore, it is not possible to remove the debris such as the feed water periodically and the pollutant is deposited on the bottom of the water tank. There is a problem that aquatic organisms are killed.

In addition, it is necessary to install a through hole for the breeding water flow in the drain pipe installed outside the water level control pipe, and it is distributed in the space formed inside the drain pipe and the water level control pipe by the installed holes, There is a problem that the aquaculture can be lost through the drain pipe together with the breeding water, and when the water tank is composed of two or more layers, there is a problem that the drain pipe is separately formed in each water tank, so that it is not space intensive.

2 is a photograph showing a single-layer water tank in which the water drainage device of the present invention is formed. The water tank is composed of a water tank body having an upward opening and a constant height and length in the front, rear, left and right directions. The bottom of the water tank body is provided with flat irregularities having a flat upper surface and longitudinally provided with air blowing means And the water tank main body has a longitudinally-formed sidewall having a net-shaped cradle.

A rib is formed in the middle of the side wall of the water tank body, a flange is formed at the end of the side wall, and a rounded portion is formed between the bottom wall and the side wall, and between the side wall and the side wall. In general, a square water tank can be constructed adjacent to a large number of water tanks, so that utilization of the farm site is higher than that of the round water tank

The drainage device shown in the lower part of FIG. 2 includes a water discharge port formed at a bottom of one side of the water tank inside the water tank, lower than the bottom surface of the water tank; A drain pipe connected to the drain port and installed at an outer portion of the water tank; And a water level control pipe installed inside the drain pipe. The water level control pipes installed in the respective drain pipes and the drain pipes are separately manufactured and assembled by assembling methods such as bolt nut assembling or fitting assembly.

In addition, when aquaculture water is discharged to a drainage port, aquatic organisms may flow together and may be lost. Therefore, a drainage channel may be provided with a mesh of a certain size smaller than the size of aquatic organisms, As shown in FIG. The water drainage barrier having a certain mesh formed in the drainage outlet is formed variable, so that the feed residue settled on the floor is collected in the drainage outlet and the drainage water formed in the drainage outlet is closed, By separating, it is possible to drain only the waste to the outside without draining the entire breeding water. Fig. 3 is a schematic view of a retractable water level control tube and a breeding water barrier membrane formed in an ejection port.

The bottom of the water tank and the bottom of the tank on either side of the water tank body can provide a bottom surface inclination so that the bottom of the tank or the bottom of the water tank can collect the discharged water or the food waste well, and if the inclination is too gentle, , It may cause inconvenience to workers who work for cleaning and the like when it is too urgent, so it is desirable to make a slope of about 3 to 7%. Thus, the debris accumulated on the bottom of the water tank can be separated into the outflow port and discharged to the outside through the drain port, so that the feed waste and the excretion of the aquatic organism are decayed in the water tank to deteriorate the water quality, There is a side.

A water level control tube is formed inside the drain pipe formed on the outer wall of the aquaculture tank so that the water in the water tank can be maintained at a certain level. That is, a certain amount of water is continuously supplied to the water tank from the feeding water inlet, and the water is drained through the water level control pipe, so that the feeding water is exchanged for a predetermined period of time. The water level adjusting pipe formed inside the drain pipe is formed as a variable water level adjusting pipe so that the height of the water level adjusting pipe can be adjusted.

The variable water level control tube is composed of an inner tube and an outer tube, and an opening is formed on the inner tube, draining the water through the opening, and the inner tube moves up and down to adjust the position of the opening, A screw thread is formed at positions corresponding to each other so that the position of the inner tube or the outer tube can be rotated to adjust the position.

It is also preferable that the opening formed in the upper part of the inner tube forms a hole smaller than the size of aquatic organisms so as to prevent the loss of aquatic organisms. Instead of forming the thread, the inner tube and the outer tube are alternately sloped A relative position between the inner tube and the outer tube may be adjusted by forming a hole and inserting a pin into the hole. Or a bellows method in which a wrinkle portion is formed on the upper portion of the water level control tube and the water level is adjusted through expansion and contraction of the wrinkle portion.

That is, if the height of the variable water level control tube is increased to adjust the depth of the water in the water tank, the water depth of the water tank is increased and drained over the water level control pipe. Conversely, if the height is lowered,

The water level control pipe installed inside the water pipe is connected to the pipe pipe formed at the lower part of the water level control pipe and the pipe assembly or fitting assembly and the pipe pipe pipe is connected to the body pipe formed at the outside of the water tank at a certain angle. In other words, one or more branch pipes may be connected to the body pipe and connected to a drainage apparatus which is drained from several multi-story water tanks through a branch pipe.

4 is a photograph showing a multi-layered aquarium drain device according to the present invention. A water tank support having a predetermined height and at least one water tank support horizontally extending from the water tank support; A water tub main body having an upward opening and a constant height and a length; A discharge port formed at a bottom of one end of the water tub lower than the bottom surface of the water tub; A drain pipe connected to the drain port and installed at an outer portion of the water tank; One or more water tanks are installed in the water pipe.

The water level control pipe installed inside the drain pipe formed on the outer side of the water tank is connected to the branch pipe pipe connected to the lower level control pipe, and the branch pipe pipe is vertically arranged between the neighboring water tank and the water tank, And the branch piping pipe may be formed facing the body pipe or may be formed in a staggered state, and at least one branch pipe may be connected to the connection pipe of the body pipe. The angle formed by the body pipe and the branch pipe is 30 to 60 ^°, and is connected to a structure that can be disassembled and assembled.

The angle of the branch piping is suitably 45 degrees. If it is lower than this, it is difficult to drain the debris included in the breeding water in the branch pipe because it is accumulated in the branch pipe. If it is higher than this, There is a problem in that it can flow back to the drain pipe coming out from another aquarium.

The drain pipe, the branch pipe, the body pipe and the water level control pipe can be assembled and disassembled, so that it is easy to clean pipes contaminated by feed water containing feed residue and contaminants, and the drainage device of the multi- And the manufacturing cost and time can be shortened by simplifying the piping system of the multi-layer water tank and saving the installation cost, thereby contributing to the spread of the facilities of the multi-layer water tank farm.

The operator can easily assemble and disassemble the drain hole of the multi-layer aquarium so that the cleaning can be easily performed, the work efficiency can be improved, the working time can be shortened, and a plurality of the aquariums can be connected and managed by one drain pipe, The piping system required to construct the water tank in a multi-layer structure can be simplified to a minimum and the installation cost can be saved, so that there is a possibility that the facilities of the multi-layer water tank farm can be widely used.
