[0004] However, the above-mentioned disclosed solution has the following deficiencies: The existing water circulation device has a small structure and a small volume, resulting in a small volume of water that can be driven, so it cannot be applied to an environment with a large water body such as a pond, and it is difficult to be fixed and used stably in the pond for a long time. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the technical problem that the existing water circulation device has a small structure and a small volume, resulting in a small volume of water that can be driven, so it cannot be applied to an environment with a large water body such as a pond, and it is difficult to be fixed and used stably in the pond for a long time, and to provide a water circulation device for a fish-vegetable symbiotic pond.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions to implement;

[0007] A water circulation device for a fish-vegetable symbiotic pond according to the present utility model includes a five-way joint; a plurality of rigid straight pipes are connected and fixed to the five-way joint; a plurality of horizontal one-way holes are formed on the side surface of the rigid straight pipe; the end of the rigid straight pipe is connected and fixed to a four-way joint; an arc-shaped pipe is connected and fixed between the four-way joints; a plurality of upward holes are formed at the upper end of the arc-shaped pipe; a first hose is vertically connected and fixed to the four-way joint; a second hose is vertically connected and fixed to the five-way joint; the upper end of the second hose is connected and fixed to a water pump.

[0008] Further, the other end of the water pump is connected and fixed to a water inlet and outlet pipe.

[0009] Further, an air pump is connected and fixed to the upper end of the first hose; a floating plate is fixed to the lower ends of the air pump and the water pump.

[0010] Further, a plurality of mounting holes are formed on the floating plate; a warning pipe is inserted into the mounting hole.

[0011] Further, the water pump is specifically a double-suction pump; a one-way valve is connected and fixed to the lower end of the first hose.

[0012] The water circulation device for a fish-vegetable symbiotic pond provided by the present utility model has the following beneficial effects:

[0013] 1. By energizing and operating the water pump, the water on the surface of the pond is discharged along the second hose, five-way joint, rigid straight pipe, four-way joint and arc-shaped pipe and through the horizontal one-way holes and upward holes. Thus, under the jet of the horizontal one-way holes forming a circular shape, the excrement and nutrients in the arc-shaped pipe are driven to move upward to the surface of the water body, and are directly absorbed by the plant roots soillessly cultivated on the water surface, enabling the plants to grow rapidly. This solves the problem that the existing water circulation device cannot drive the water circulation movement of deep and distant water bodies.

[0014] 2. The floating plate isolates the air pump and the water pump from the water surface, enabling them to remain dry and operate normally. By energizing and operating the air pump, the air is sucked and conveyed into the first hose, four-way joint, rigid straight pipe, horizontal one-way holes and upward holes and discharged. Through the horizontal one-way holes in the same direction, the discharged air can blow the fish excrement accumulated at the bottom of the pond upward, and is driven by the air discharged from the upward holes to the upper end of the pond water body, and is then absorbed by the plant roots planted on the water surface of the pond. Thus, the nutrients in the excrement produced by the fish are fully utilized, and the soilless cultivation nutrients of the plants are recycled in the pond. At the same time, oxygen can be added to the water body while injecting gas, keeping the growth environment of the fish comfortable. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, under the jet of the horizontally circular one-way holes 3, the excrement and nutrients in the arc-shaped pipe 5 are driven to move upward to the surface of the water body, and are directly absorbed by the plant roots of the soilless cultivation on the water surface, so that the plants can grow rapidly, solving the problem that the existing water circulation device cannot drive the water circulation of deep and far-reaching water bodies.

[0024] The other end of the water pump 10 is connected and fixed to a water inlet and outlet pipe 12; during operation, the water inlet and outlet pipe 12 is inserted below the liquid level of the pond, so that the water pump 10 can transport the water on the surface layer of the pond to the bottom of the pond for circulation when it is energized, so that the nutrients in the fish excrement at the bottom of the pond can be driven to rise above the pond, and are fully absorbed and utilized by the roots of the soilless cultivation plants planted on the surface of the pond, so that the soilless cultivation has rich nutrients and can grow rapidly, solving the problem that the existing water circulation device cannot drive the water circulation of deep and far-reaching water bodies.

[0025] The upper end of the first hose 7 is connected and fixed to an air pump 8; a floating plate 9 is fixed to the lower ends of the air pump 8 and the water pump 10; during operation, the floating plate 9 separates the air pump 8 and the water pump 10 from the water surface, so that they can keep themselves dry and can be used normally; by energizing the air pump 8 to work, the air is sucked and transported into the first hose 7, four-way joint 4, hard straight pipe 2, horizontal one-way holes 3 and upward holes 6 and discharged. Through the horizontally one-way holes 3 in the same direction, the discharged air can blow the fish excrement accumulated at the bottom of the pond upward, and is driven to the upper end of the pond water body by the air discharged from the upward holes 6, and is absorbed by the plant roots planted on the surface of the pond water body, so that the nutrients in the excrement produced by the fish are fully utilized, and the soilless cultivation nutrients of the plants are recycled in the pond; at the same time, oxygen can be added to the water body while injecting gas, so that the growth environment of the fish is kept comfortable.

[0026] A plurality of mounting holes 13 are formed in the floating board 9; a warning tube 14 is inserted into the mounting hole 13; during operation, a labeling object and a warning object can be inserted through the warning tube 14, so as to facilitate searching and positioning, thereby facilitating the management and connection of soilless cultivation plants, and solving the problem that the existing water circulation device is placed in the water body and cannot be accurately and quickly searched.

[0027] The water pump 10 is specifically a double-suction pump; a check valve is connected and fixed to the lower end of the first hose 7; during operation, the medium passing through the first hose 7 can only move from top to bottom through the check valve, so that when the water pump 10 is working, pond water will not be transported into the air pump 8 and cause damage. At the same time, the water pump 10 is specifically a double-suction pump. When the water pump 10 transports water in the reverse direction, the water at the bottom of the pond can be absorbed through the horizontal one-way hole 3 and the upward hole 6 and discharged above the pond water body through the water inlet and outlet pipe 12, so as to be absorbed by the roots of the soilless cultivation plants floating on the pond, so that the nutrients in the excrement of the fish can be timely absorbed by the roots of the plants, so that the plants can continuously and timely absorb nutrients; when the water pump 10 transports water in the forward direction, the water above the pond water body is absorbed through the water inlet and outlet pipe 12 and then conveyed along the second hose 11 to the horizontal one-way hole 3 and the upward hole 6 for discharge, so that the nutrients generated by the feces of the fish located below the pond can be rotated upward to the surface of the water body, so that they can be absorbed by the roots of the soilless cultivation plants floating on the water body, so that the roots can continuously absorb the nutrients from the excrement of the fish during growth, thereby realizing the symbiotic cultivation of fish and vegetable plants, and solving the problem that the existing water circulation device is difficult to adapt to the large environment.

[0028] With the above solution, when the utility model is in use, the water pump 10 is powered on and operates to discharge the water on the surface layer of the pond along the second hose 11, five-way joint 1, rigid straight pipe 2, four-way joint 4 and arc pipe 5 and through the horizontal one-way holes 3 and upward holes 6. Thus, under the jet of the horizontal one-way holes 3 formed in a circular ring shape, the excrement and nutrients located in the arc pipe 5 are driven to move upward to the surface of the water body, and are directly absorbed by the plant roots of the soilless cultivation on the water surface, so that the plants can grow rapidly, solving the problem that the existing water circulation device cannot drive the water circulation movement of deep and distant water bodies; the inlet and outlet pipe 12 is inserted under the liquid level of the pond, so that when the water pump 10 is powered on and operates, the water on the surface layer of the pond is transported to the bottom of the pond for circulation movement, so that the nutrients in the fish excrement located at the bottom of the pond can rise above the pond, and are fully absorbed and utilized by the roots of the soilless cultivation plants planted on the surface of the pond, so that the soilless cultivation has rich nutrients and can grow rapidly, solving the problem that the existing water circulation device cannot drive the water circulation movement of deep and distant water bodies; the floating plate 9 isolates the air pump 8 and the water pump 10 from the water surface, so that they can keep themselves dry and can be used normally; when the air pump 8 is powered on and operates, the air is sucked and transported to the first hose 7, four-way joint 4, rigid straight pipe 2, horizontal one-way holes 3 and upward holes 6 and discharged. Through the horizontal one-way holes 3 in the same direction, the discharged air can blow the fish excrement accumulated at the bottom of the pond to move upward, and is driven by the air discharged from the upward holes 6 to the upper end of the pond water body, and is then absorbed by the plant roots planted on the surface of the pond water body, so that the nutrients in the excrement produced by the fish are fully utilized, and the soilless cultivation nutrients of the plants are recycled in the pond; at the same time, when injecting gas, oxygen can be added to the water body, so that the growth environment of the fish is kept comfortable; through the warning pipe 14, label objects and warning objects can be inserted, so that it is convenient to search and locate, and thus it is convenient to manage and connect the soilless cultivation plants, solving the problem that the existing water circulation device is located in the water body and cannot be accurately and quickly searched; through the one-way valve, the medium passing through the first hose 7 can only move from top to bottom, so that when the water pump 10 is working, the pond water will not be transported into the air pump 8 and cause damage. At the same time, the water pump 10 is specifically a double-suction pump. When the water pump 10 transports in the reverse direction, the water at the bottom of the pond can be absorbed through the horizontal one-way holes 3 and upward holes 6 and discharged above the pond water body through the inlet and outlet pipe 12, and is then absorbed by the roots of the soilless cultivation plants floating on the pond, so that the nutrients in the fish excrement can be timely absorbed by the plant roots, so that the plants can continuously and timely absorb nutrients;When the water pump 10 conveys water forward, it absorbs the upper water of the pond water body through the inlet and outlet pipe 12 and then conveys it along the second hose 11 to the horizontal one-way hole 3 and the upward hole 6 for discharge. As a result, the nutrients generated by the feces of the fish located below the pond can be rotated upward to the water surface, so that they can be absorbed by the plant roots using soilless cultivation floating on the water body. The roots can continuously absorb the nutrients from the fish excrement during growth, thus realizing the symbiotic cultivation of fish and vegetable plants, and solving the problem that the existing water circulation device is difficult to adapt to the large environment.
