Description

a fish farming device

technical field

The utility model relates to a fish breeding device.

Background technique

The known industrialized fish farming devices are generally provided with one or more cylindrical culture tanks in the factory building, and an outlet pipe capable of maintaining the water level of the culture tank is provided at the center of the lower part, and a retaining net is provided at the entrance of the water outlet pipe. , to prevent the cultured fish from escaping from the water outlet, and at the same time allow fish excrement and uneaten bait to enter the water outlet pipe. A culture tank inlet pipe is arranged on the upper part of the side wall of the culture tank, and the axis line of the water outlet is less than the culture tank. The outer diameter of the tank is tangent to the circumference, and the water inlet of the water inlet pipe is connected with the intermittently working water pump. This drainage process can discharge the fish excrement and uneaten bait in the breeding tank, so as to purify the living environment of the fish and be more conducive to the growth of the fish. The shortcoming of this kind of fish farming device is that, because the water pump keeps starting and stopping for many years, this will greatly shorten the service life of the water pump, motor and electrical parts, cause the device cost and maintenance cost to rise, plus the consumption of electric energy, It will also greatly increase the cost of fish farming.

Utility model content

In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a new technical solution, which makes the fish farming device simple, low in cost, convenient in maintenance and reduces energy consumption while completing the same function of the prior art.

The technical scheme of the utility model is as follows:

A fish farming device, comprising a cylindrical culture tank, a culture tank outlet pipe located at the center of the bottom of the culture tank capable of controlling the water level of the culture tank, and a shelf net located at the entrance of the culture tank outlet pipe, characterized in that: it also includes a The water tank on the upper part of the tank has a ventilation pipe on the top, the water tank inlet pipe on the side wall of the water tank, and the siphon pipe fixed in the water tank. Its aperture is adapted to the aperture of the water tank inlet pipe. Pass through the bottom surface of the water tank and enter the set water surface of the culture tank inclined downward for a certain distance, and the axis of the siphon outlet is tangent to the circumference that is less than the outer diameter of the culture tank.

A convex top can be arranged on the upper part of the water tank, and the upper part of the siphon enters near the upper part of the inner space of the convex top.

A groove can also be provided at the bottom of the water tank, the water inlet of the siphon enters near the bottom of the groove, and at least one leak hole is occupied on the wall of the siphon below the upper plane of the groove.

It can be seen from the above first solution that since the water inlet pipe of the water tank is constantly filling the water tank, when the water level of the water tank rises to the water level that causes the siphon to produce a siphon, the water flow rate in the siphon will be very large, about half of the normal flow rate. 4-5 times, and due to the special arrangement of the siphon outlet, the high-speed water flow will make the water in the breeding tank swirl and discharge the fish excrement and uneaten bait through the net and the outlet pipe of the breeding tank. It can be seen that the technical effect produced by the technical solution of the utility model is equivalent to the technical effect produced by the water pump water supply of the known technology, but the technical solution of the utility model is simpler in structure and reliable in operation, which reduces device cost and maintenance cost, and avoids Energy consumption; As can be seen from the second solution, since the convex top is provided on the top of the water tank, the volume of the convex top cavity suddenly becomes smaller, and the speed of the water level in the lower cavity is also accelerated, which makes The siphon that is located in the convex top will form a more reliable siphon phenomenon; as can be seen from the third technical scheme, since a groove is arranged at the bottom of the water tank, and at least one is occupied on the siphon wall near the plane below the groove. Leakage hole, when the siphon phenomenon goes to the end, only the water in the groove, and the water injected by the water tank inlet pipe has no time to enter the groove, the water in the groove will be quickly sucked up by the siphon tube, and at the same time, the air leakage in the lower part of the siphon tube The hole will also suddenly inject air into the siphon to more reliably stop the siphon.

In the figure, 1 is the breeding tank, 3 is the water outlet pipe of the breeding tank, 4 is the gear net, 5 is the water tank, 51 is the ventilation pipe, 52 is the convex top, 53 is the groove, 6 is the water inlet pipe of the water tank, and 7 is the siphon. 71 is an air leakage hole.

Detailed ways

Referring to Fig. 1 and 2, a kind of fish culture device, comprises cylindrical fish culture tank 1, is provided with culture tank outlet pipe 3 at the bottom center of culture tank, is located at the shelf net 4 at the inlet of culture tank outlet pipe, also includes setting In the water tank 5 on the top of the breeding tank 1, the water tank inlet pipe 6 is arranged on the side wall of the water tank, and is connected with the water source by a valve. Located near the bottom of the groove 53 located at the lower part of the water tank, there are two air leakage holes 71 on the wall of the siphon tube lower than the upper plane near the groove, and the upper part of the siphon tube enters the upper part of the inner cavity of the convex top 52 located at the upper part of the water tank Nearby, the top wall of the convex top is provided with a ventilation pipe 51, and the outlet of the siphon passes through the bottom surface of the water tank and enters a certain distance below the setting water surface of the breeding tank inclined downward. tangent to the circumference of .

The utility model works like this: open the valve on the water inlet pipe 6 of the water tank and inject water into the water tank. The siphon tube injects into the breeding tank at high speed, and makes the water in the breeding tank form a vortex flow state. When the water level in the water tank drops to the groove, the water level drops faster, and the air has passed through the leak hole almost at the same time as the water inlet of the siphon tube is exposed to the water surface. Entering the siphon tube destroys the siphon phenomenon and terminates the siphon phenomenon. Since the water inlet pipe of the water tank keeps filling the water tank, after a period of time, when the water level rises to produce a siphon phenomenon, it starts to inject water into the breeding tank again, until the water level in the breeding tank rises to the water level controlled by the outlet pipe of the breeding tank, the water tank is turned off The valve of the water inlet pipe puts the fish to be cultured into the breeding tank and puts in the bait. After a period of time, the valve of the water inlet pipe of the water tank is opened, and the water tank can intermittently provide the water to the breeding tank to make the water in the breeding tank swirl. The new water, due to the swirling effect, makes the excrement of the fish and the uneaten bait all concentrate on the rack net at the center, and flows out through the outlet pipe of the breeding tank to purify the water in the breeding tank.
