Description

Technical Field

[0001] This patent relates to the technical field of fish farming equipment, and specifically relates to a fish transportation, breeding tank and its breeding method. Background Art

[0002] Fish breeding and transportation tanks, as the name implies, are used for breeding, feeding and transporting fish. Some are for feeding and transporting fry, while others are for breeding and transporting large fish. Existing fish breeding and transportation tanks supply air through an air pump and air pipes to increase the oxygen content. During long-term transportation and feeding, impurities and fish food deposited in the tank are difficult to clean, seriously polluting the water quality. The harmful gases generated by the fermentation of fish food and feces in fish ponds and the red tide in the sea are not conducive to the survival and growth of fish, and may even cause a large number of fish deaths, resulting in serious losses. When the fish in fish ponds or cages need to be sold or transferred, more than 90% of the pond water is drained, and then people catch fish in the turbid muddy water. People use nets to catch fish weighing 1 to 90 catties out of the water, and the fish are squeezed against each other, causing internal injuries and greatly reducing their lifespan. Then, people carry the fish 1 to 900 meters away and pour them into vehicles or containers for transportation, which requires a large amount of labor and causes harm to the fish. Summary of the Invention

The containers, tanks, and pipes are provided with 2 to 9 inlets and outlets, and some of the inlets and outlets are connected by pipes. At least one pipe and one outlet are provided with or connected to an air pump, or connected to the air pump with a tee and an air pipe. It is characterized in that: the containers, tanks, and pipes are placed in the fish pond, and when the inlet water sinks, plankton and fish are sucked in. After putting osmanthus fry into the containers, tanks, and pipes, cover them with a net or use a lid or door to screw and close. The air pump inputs compressed air into the outlet of the containers, tanks, and pipes. While pushing the water, fish food, and feces away, the water, fish food, and feces in the containers, tanks, and pipes replenish the outlet, and push the air away to increase the oxygen in the fish pond. When the water in the containers, tanks, and pipes decreases, the floating part of the containers, tanks, and pipes emerges above the water surface, and the water flows into the fish pond from the lower outlet of the containers, tanks, and pipes. Optionally, at least 1 to 9 air pipes are inserted through holes in the pipe body, and the pipe orifice is wrapped with an eight-shaped net or blocked with a plug with 1 to 9 holes to narrow the orifice diameter of the pipe to keep the fish in the pipe.

When the box sinks, the pneumatic and hydraulic cylinders shorten to generate pressure and compressed air. The air pump and the air cylinder input compressed air into the pipe at the outlet of the box. While pushing the water, fish food, and feces in the pipe away, the water, fish food, and feces in the box are replenished to the pipe at the outlet, and the air pushed out of the pipe is used to oxygenate the fishpond. As the water in the box decreases, the box floats up, and the pneumatic and hydraulic cylinders extend to inhale air and liquid; the inlet and the pipe generate negative pressure to inhale water, plankton, and fish. The air pump and the pressure storage tank input compressed air and pressure into the pneumatic and hydraulic cylinders to extend and lift the box so that part of it is exposed above the water surface, and the water flows into the fishpond from the lower outlet of the box; the pneumatic and hydraulic cylinders input compressed air and pressure to shorten and pull the box underwater, and the inlet and the pipe intake water to inhale water, plankton, fish, and shrimp.

Optionally, the ports of the cylinder are connected to the outlet and inlet of the box by pipes.

[0007] Optionally, the floating and sinking pressure plate is provided with 1 to 9 holes. The features are as follows: Water and fish are poured into the box from vehicles, the shore, or land. The oxygen-deficient water flows through the floating and sinking pressure plate to the bottom of the box, causing the airbag to hold up the floating and sinking pressure plate. The water and fish above cause the floating and sinking pressure plate to sink, squeezing out the precipitated impurities, fish food, feces, and oxygen-deficient water to leave the box. Optionally, a water floating device is provided below the holes. Optionally, the floating and sinking pressure plate is provided with a foot-operated air pump. The inlet pipe of the box is connected to the inlet of the foot-operated air pump. The features are as follows: Water and fish are poured into the box from vehicles, the shore, or land.

The air compression storage tank inputs compressed air to the air inlet at the bottom of the box through a pipe, squeezing out the precipitated impurities, fish food, feces, and oxygen-deficient water, which leave the box through the sewage outlet at the bottom of the box. At this time, the compressed air entering diffuses around the airbag, causing the floating and sinking pressure plate to lose buoyancy. Under the action of the weight of water and fish, the floating and sinking pressure plate presses down to make both water and air leave the box, and they are guided by pipes to places where pressure is required. Optionally, a check valve is installed on the floating and sinking pressure plate.

[0009] Optionally, a tee is installed at the sewage outlet at the bottom of the box and is respectively connected by pipes provided with switches. One of the pipes is connected to the inlet at the upper part of the box. The features are as follows: The oxygen-deficient water and air at the bottom of the box are squeezed out to leave the box, enter the pipe with a switch, and are precipitated and filtered. The mixed purified water and air are transported and sprayed into the box through the pipe connected to the upper part of the box to make the water oxygen-rich. When the box is sealed, these pressurized water and air increase the pressure on the floating and sinking pressure plate to press down.

[0010] Optionally, the air cylinder, liquid cylinder, foot-operated air pump, and floating and sinking pressure generate pressure and compressed air, which are guided by pipes to be stored in the air compression storage tank.

[0011] Optionally, the air compression storage tank inputs compressed air to the vortex tube, converts it through the vortex tube to obtain the required air, and then inputs it to the air inlet at the bottom of the box through a pipe.

[0012] Optionally, there is a gap between the floating and sinking pressure plate and the barrel wall of the box. The floating and sinking pressure plate is provided with a downward concave rubber bowl. It is characterized in that when the box is filled with water for fish farming, the water above the floating and sinking pressure plate and the precipitated impurities flow from the periphery of the rubber bowl to the lower part. When the floating and sinking pressure plate floats upward, the volume below the floating and sinking pressure plate increases and the pressure decreases. When the water and fish above reach a certain weight, the floating and sinking pressure plate presses down the rubber bowl against the box wall to prevent air, water, and precipitated impurities from leaking above the floating and sinking pressure plate. When the pressure is sufficient to open the one-way valve, compressed air, water, and precipitated impurities enter the pipeline. At the same time, air, water, and required substances outside the box enter above the piston from the upper end of the box.

[0013] This patent also provides a cultivation method for the fish tank. The cultivation method is applied to the fish tank and includes fish farming in waters such as fish ponds, reservoirs, rivers, seas, land, transportation, etc. The inlet and pipe diameters of containers, boxes, pipes, etc. are 1 to 90 cm. By sucking in water, plankton, and fish and discharging and sucking water, the functions of fish farming and fish catching are achieved.

[0025] Example 10 A fish-raising box, as Figure 10 shown, the pipe body is provided with openings for inserting an air delivery pipe 55, and the pipe orifice is wrapped with a figure-eight net 56 or a plug cap 57 with 1 to 9 holes. Optionally, the outlets of the box and the pipe are wrapped with a cloth bag 58.

[0026] The present patent also provides a cultivation method for a fish tank, which is applied to the fish tank provided by the present patent and includes containers, tanks, pipes, etc. that can hold and contain liquids and water, and are provided with multiple inlets and outlets. An air pump is provided at the outlet. The characteristics are as follows: When water enters the container and the container sinks, air is input into the container, pushing the water away to oxygenate the fishpond, and the water flows from the container into the fishpond; multiple holes are opened on the pipe body and one pipe orifice is blocked by an open plug. Air is sprayed into the pipe to move the water and fish into the pipe, and the water flows away from the holes and orifices; holes are opened on the pipe body to input air, and the pipe moves forward to collect fish. An air and hydraulic cylinder lifts the tank so that part of it is exposed above the water surface, and the water flows from the tank into the fishpond while the fish are inside the tank; the tank is pulled into the water to suck in water, plankton, fish, and shrimp; an air cylinder is additionally installed on the air and hydraulic cylinder, and a basin for growing crops is installed on it; air is input into the tank, and the floating and sinking pressure plate sinks to suck in water, plankton, fish; the telescopic air cylinder pushes and pulls the floating and sinking pressure plate to float and sink up and down, squeezing out the precipitated impurities, fish food, feces, and oxygen-poor water from the tank body; a foot-operated air pump is provided on the floating and sinking pressure plate to generate compressed air and spray it into the tank body; the oxygen-poor water and air at the bottom are squeezed out, precipitated, filtered, and then sprayed into the tank from the upper part to enrich the water with oxygen. The pressurized water and air cause the floating and sinking pressure plate to press downwards; the air and hydraulic cylinder, foot-operated air pump, and floating and sinking pressure generate pressure and compressed air, which are guided by pipes to be compressed and stored in an air storage tank; the required air is obtained through a vortex tube conversion and input into the air inlet; a rubber bowl is provided to press downwards so that air, water, and precipitated impurities enter the pipeline. At the same time, air, water, and required substances outside the tank enter from the upper end. The tank is placed on a shelf and a flexible hose is placed in the fishpond. A water pump pumps water to suck the water and fish in the fishpond into the tank, and the water is continuously drained outside the fishpond to drain the fishpond dry while the fish remain in the tank.

[0027] This patented fish tank is equipped with a floating and sinking pressure plate, and the floating and sinking pressure plate is provided with holes, a water floating device, an airbag, a telescopic cylinder, and a foot-operated air pump. The weight of the telescopic cylinder, fish, and water exerts pressure on the floating and sinking pressure plate, pushing away the water, air, sediment, etc. that can be pressed below, and frequently cleaning the sludge, garbage, and oxygen-deficient water deposited at the bottom. The air blocks the water from the floating and sinking pressure plate, the water floating device, and the airbag, causing them to lose buoyancy. Therefore, the floating and sinking pressure plate generates pressure and suction. The water pressed into the pipe comes into contact with air and starts to aerate. Therefore, there is sufficient time. The sediment is pressed into the pipe and discharged by opening the pressure check valve below. The water enters the upper inlet of the box through the pressure check valve above and is recycled. The material waits for the one-way valve at the inlet to utilize the pressure check valve above and allows the materials and feed required by the fish to enter the upper part of the box during the time when there is no pressure. The fish tank is placed in the water of a fishpond or the sea. The pressurized water is sprayed out from the discharge port in the required direction and place, and the fish tank can be moved to the required place. The suction inlet connecting pipe sucks in the required water and plankton, providing food for the oysters. The compressed storage tank allows air to enter, causing the floating and sinking pressure plate to lose buoyancy and its base to sink, pressing the water, air, and sediment into the pipe. The water enters the upper inlet of the box and is recycled. The compressed storage tank inputs pressure to the telescopic cylinder to shorten it. At the same time, the floating and sinking pressure plate presses downward, pressing the water and sediment into the sedimentation part for filtration. The sediment is discharged from the outlet, and the water is sprayed into the air from the spray port for aeration and then enters the box for recycling. The telescopic cylinder receives pressure input from the compressed storage tank at its corresponding inlet, driving the floating and sinking pressure plate to move up and down, enabling the compressed air, water, and sediment impurities to enter the pipeline. At the same time, the foot-operated air pump generates pressure and is connected to the compressed storage tank and the required places by pipes. The floating and sinking pressure plate presses downward to press the water and air into the upper inlet of the box for recycling. The fish and water enter above the floating and sinking pressure plate through the fish inlet and the one-way valve, and then water is injected into the fish transportation tank by another fish transportation tank to make the fish transportation tank operate. When fish are needed, most of the water in the box is drained, and then the switch at the fish discharge port is opened to release the fish, which saves time and effort.
