Description

Oxygen Supplement for Fish Farms

The present invention relates to an oxygen supplement for fish farms to compensate for the insufficient oxygen content of fish farms, and in particular, by supporting the motor to the upper surface of the water by means of a float, the flying wing coupled to the shaft of the motor is in contact with the water surface The present invention relates to an oxygen supplement for fish farms configured to supplement the dissolved effect of oxygen by scattering and watering water on the surface by the rotation of a flying blade.

In general, fish farms are able to trap fish and fish them, and by putting a large number of fish in the confined fresh water in a narrow space, the fish are limited in oxygen concentration in the fish farms, which limits the activity of fish Eating less can result in slower growth or, in severe cases, fish die. In addition, fish food and excreta are accumulated on the bottom to form a float, which not only contaminates the water quality seriously but also promotes a decrease in oxygen dissolved amount.

In order to solve the above problems, oxygen is supplied to the fish farm by using aberrations, air compressors or bubble generation in the conventional fish farm. These oxygen supplements are usually supplied to the air and discharged to supply oxygen contained in the air discharged into the water. Among them, the oxygen dissolver announced by Korean Utility Model No. 83-2014 is representative. have.

This oxygen dissolving device installs a rotating mandrel made of a hollow part with a narrower cross section of the discharge part than the suction part inside the casing in which the air hole is perforated, and the upper part thereof is connected to the mandrel of a known motor and a cross-shaped material, and is known at the lower end. It is made by attaching the impeller. According to this oxygen dissolving machine, when the impeller is deeply inserted into the water and the motor is driven, air flows into the hollow part of the rotating mandrel through the vent hole of the casing, and is discharged into the water through the end of the rotating mandrel in the water, and the oxygen contained in the air It is supplied in water.

However, there are the following problems in the above oxygen dissolving group.

First, the impeller is installed on the outer circumferential surface of the end of the rotating mandrel and is exposed to the water, so that only the water in the water is stirred while rotating the impeller, and almost no suction force is actually generated. That is, only when the impeller is installed inside the hollow of the rotating mandrel or inside the casing, the axial flow suction input can be generated by the rotation of the impeller, and the air can be sucked by the axial flow suction input. However, in the oxygen dissolving device of the prior art, since suction force which can suck air only by the rotational force of the rotating mandrel is generated, the suction force hardly occurs.

Second, since the hollow of the rotating mandrel acts as a passageway through the water and the outside, the suction force of the air hardly works because the water is filled to the surface of the hollow.

Third, it is impossible to inhale the air and discharge it into the water by the oxygen dissolving agent, but even if the air is discharged into the water, the air rises immediately and escapes onto the water surface. Degrees fall.

Fourth, since there is no means to support the oxygen dissolving device at any place in the fish farm, there is no choice but to fix it at the edge of the fish farm, so that the oxygen dissolution is not only lowered, but also the water surface of the fish farm cannot be coped with. .

Fifth, if the water level is changed and the water level rises above the vent or the impeller, the oxygen dissolving function cannot be achieved at all, and the oxygen dissolving agent must be reinstalled each time the water level changes.

Furthermore, since the impeller is rotated underwater, the resistance of the water is greatly increased. Therefore, the power consumption is high and the maintenance cost is increased, and floating or water plants may be caught by the impeller, causing the motor to stop driving or damaging the impeller or the motor. In some cases, when the impeller is exposed to water, the fish approaching the impeller may die by hitting the impeller.

The present invention was devised to solve the conventional problems as described above, can be installed not only to improve the dissolved oxygen, but also to be automatically lifted according to the surface of the fish farm, and also made for a fish farm made to reduce the maintenance cost To provide an oxygen supplement.

In addition, an additional object of the present invention is to provide an oxygen supplement for fish farms that can prevent the impeller and the motor from being damaged and also protect the fish from being killed by the impeller.

In order to achieve the above object, the oxygen supplement device according to the present invention, three buoys arranged in a triangle, a triangle for fixing the buoys in turn, three inclined support rods inclined upwardly in the direction in which the bottom is connected to each other to meet each other And a square pyramid-shaped support frame having a support connecting the upper ends of the inclined support bars to each other; a motor fixed in an inverted state to the support ring; an impeller that is in contact with the surface of the motor and is in contact with the water surface; and the triangle It is installed on both sides of the vertically characterized in that it comprises a biped fixing column for supporting the support frame in accordance with the level of the fish farm.

In addition, according to the present invention, the hook is caught on the interruption of the rods of the triangle is installed in the three directions of the upper end of the upper opening and the bottom may be provided with a safety net consisting of a safety net.

According to the oxygen supplement device of the present invention configured as described above, when the motor is driven, the impeller in contact with the water surface is rotated by the rotation of the motor shaft. Accordingly, the water on the surface is scattered finely in all directions by the rotation of the impeller, thereby becoming almost atomized and contacting the air, thereby increasing the contact surface area of the water droplets and the air scattered, thereby increasing the oxygen dissolved degree. And, when the height of the surface is increased or the surface is lowered by the flood, etc., the lifting frame coupled to the triangle is lifted and lifted by the support frame, so that the impeller always touches the surface regardless of the water level. Will be maintained. In addition, it is possible to protect the impeller and the motor by preventing the access to the impeller by the safety floats, such as water plants or floats, it is possible to protect the fish by preventing the fish from accessing the impeller.

Other features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

As shown in FIG. 1, reference numeral 1 is a support frame for supporting a motor, and includes three sub-balls 11, 11, 11 arranged in a triangle, and a triangle 12 that sequentially connects the sub-balls 11. , Three inclined support rods 14, 14, 14 extending inclined upwardly in a direction in which the lower ends are connected to the sub-balls 11, and a support ring 15 connecting upper ends of the inclined support rods 14 to each other. ) The braces 11 may be fixed by fixing bolts 13 penetrating through them and coupled to respective corners of the triangle 12, and the inclined support rods 14 are coupled to the fixing bolts 13 to substantially fix the braces. (11) can be connected.

Therefore, the support frame 1 is in the form of a substantially square flame, the support ring 15 is located at the apex, and is placed on the water surface by the floats 11.

The motor 2 is fixed to the fixing bolt 22 which is fastened through one side of the support ring 15 by being supported by being inserted in an inverse position to the support ring 15 of the support frame 1 so that the shaft 21 extends underwater. Is fixed by. The upper and lower surfaces of the motor 2 are respectively provided with a waterproof plate 29 to protect the motor 2. The impeller 23 is fixed to the shaft 21 of the motor 2 and is in contact with the water surface. The impeller 23 is coupled to the lower end of the shaft 21 of the motor 2, for example, by coupling the fixing socket 25 to the shaft of the motor 2 through the connecting socket 24, the impeller ( 23 is condensed by fastening the fixing shaft 25 to the lower shaft 26 through the connecting socket 24, the lower shaft is condensed. Reference numeral 27 denotes a fixing nut for fixing the imafel 23 to the lower shaft 26, and reference numeral 28 denotes a power lead wire for supplying power to the motor 2.

Therefore, when power is supplied to the motor 2 through the power lead wire 28, the impeller 23 is rotated in accordance with the rotation of the motor 2 shaft to scatter the water on the surface of the water can be diffused in all directions in the atomized state. .

On the other hand, according to the present invention, the lifting ring 31 is in turn coupled to both rods of the triangle 12, the fixing column (3) is vertically inserted into the lifting ring (31) in turn. The holding pillars 3 are preferably inserted into the lifting ring 31 so that the support frame 1 can be lifted by the lifting ring 31 being lifted along the holding pillars 3. The lower end is preferably fixed to the bottom of the fish farm so that the support frame 1 does not move from side to side. Therefore, when the water level is changed, the lifting ring 31 is lifted along the stationary pillars 3 by the buoyancy of the floats 11, and accordingly, the support frame 1 can be lifted according to the water level by lifting the triangle 12. . That is, the impeller 23 can maintain the state which is always in contact with the water surface even if the water level changes.

In addition, according to the present invention, the upper end is supported on the triangle 12 may be further provided with a water safety tool (4) located in the lower water of the impeller (23). Since the hooks 41 caught in the rod stop portions of the triangle 12 are sequentially installed in three directions around the upper end of the safety guard 4, the safety guard 4 can be supported with the upper end raised to the surface of the water.

The bottom of the underwater safety tool 4 is preferably made of a safety net (42). Therefore, the safety ball 4 is in the shape of a bucket, the upper diameter of the safety ball 4 is preferably made approximately the same as the diameter of the circle connecting the rods of the triangle (12). Therefore, when water on the surface is scattered by the impeller 23 and is reduced, water from the lower part of the safety zone 4 is sucked and scattered through the safety net 42, so that suspended matter or water plants are caught in the safety net 42. Since it is blocked from access to the (23) side, floats and plants are not caught by the impeller 23.

According to the oxygen supplement device of the present invention configured as described above, when the motor 2 is driven, the impeller 23 in contact with the water surface is rotated by the rotation of the motor shaft 21. Since the impeller 23 is in contact with the surface of the water, the water of the water surface is finely atomized and scattered by the rotation of the impeller 23, so that the droplets in the nearly atomized state come into contact with the air. The total surface area of contact with air is widened, which increases oxygen solubility. In addition, since the impeller 23 rotates in contact with the surface of the water, it hardly receives rotational resistance due to water, thereby reducing the power required to rotate the impeller 23. In fact, a comparison experiment using the oxygen supplement device according to the present invention with a 200 watt motor 2 and the conventional oxygen supplement device with a 1 kilowatt capacity motor was used to supply oxygen to the water using the oxygen supplement according to the present invention. It turned out that one side can obtain the outstanding effect.

For example, when the height of the surface is increased or the surface is lowered due to flooding or the like, the lifting ring 31 coupled to the triangle 12 is lifted by the buoyancy by the floats 11, and thus the angle of the triangle 12 connected thereto is increased. As the support frame 1 is lifted by lifting, the impeller 23 always keeps in contact with the water surface regardless of the water level fluctuation. Thus, the impeller 23 is always rotated while the motor 2 is being driven, and thus the water of the water surface. This can be scattered continuously. When water on the surface of the water near the impeller 23 is reduced by the water of the water surface scattered by the impeller 23, the water in the lower portion of the underwater safety tool 4 is applied to the safety net 42 by the suction force by the rotation of the impeller 23. By being replenished with water through the water, fish as well as floats and plants are hooked to the safety net 42 and are blocked from access to the imefeller 23.

As described above, according to the oxygen supplement device according to the present invention, the impeller 23 is rotated in contact with the water surface, so that the water is easily scattered in all directions, and the water droplets and air scattered by the finely atomized state are scattered. Since the contact surface area with, the oxygen dissolved degree is remarkably improved, so that the growth of fish can be promoted to shorten the fishing period, thereby increasing the catch amount.

In addition, it is convenient to install the oxygen supplement because it can be supported at any place of the fish farm by allowing the oxygen supplement to float on the surface by the floats (11).

In addition, the support frame 1 can be elevated so that the impeller 23 can be in contact with the water at all times regardless of the water level change even without adjusting the height of the oxygen supplement, so there is no need to reinstall the oxygen supplement according to the water level. Not only is the maintenance easy, but also oxygen can be supplied by scattering water at all times while the motor 2 is being driven, so that the dissolved oxygen is further increased.

In addition, since the impeller 23 is rotated in contact with the water surface, since the resistance of water is not largely received, power consumption can be reduced, thereby reducing maintenance costs.

In addition, the provision of the underwater safety tool (4) to block the floating material, water plants and the like so as not to catch the impeller 23, the drive of the motor 2 is interrupted, or the imager 23 or the motor 2 may be damaged. It can be excluded, and the fish is also blocked by the underwater safety sphere (4) to approach the impeller 23, the fish is prevented from hitting the impeller 23 is prevented.
