Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment, and in particular to an oxygenation and sewage discharge device for aquaculture ponds. Background Technology

[0002] In the process of aquaculture, fish pond drainage is an indispensable link. Impurities floating on the water surface in the pond during the breeding or raising of fish fry are not easy to collect. Long-term accumulation can easily lead to the deterioration of water quality in the pond. In addition, the limited oxygen supply in the pond greatly affects the survival rate of fish fry. Summary of the Invention

[0003] This invention addresses the technical problems of existing aquaculture ponds, such as difficulty in collecting impurities, poor sewage discharge, and limited oxygen supply, which are detrimental to the survival of fish fry. It provides an aquaculture pond oxygenation and sewage discharge device that can both supply oxygen to the pond and effectively collect impurities.

[0004] Therefore, the technical solution of this utility model is an oxygenation and sewage discharge device for aquaculture ponds, comprising an aquaculture pond, an air inflation device on the outside of the aquaculture pond, an air inlet pipe fixedly installed on the upper part of the aquaculture pond, the air inflation device being connected to the air inlet pipe, a valve being provided on the air inlet pipe, an air guide pipe being provided at the other end of the air inlet pipe, a nano-air pipe being fixedly installed at the bottom of the aquaculture pond, the nano-air pipe being connected to the air guide pipe; a sewage discharge pipe being provided in the center of the aquaculture pond, a reducing pipe being connected above the sewage discharge pipe, a sewage collection pipe being connected at the other end of the reducing pipe, and a sieve hole being provided on the upper part of the sewage collection pipe.

[0005] Preferably, the lower end of the air guide tube is provided with a three-way valve, the upper end of the three-way valve is connected to the air guide tube, and the other two ports of the three-way valve are connected to the nano-air tube.

[0006] Preferably, the nanotube is fixed to the inner edge of the bottom of the aquaculture pond by a snap fastener.

[0007] Preferably, the sewage collection pipe and the reducing pipe are connected by threads, and the height of the sewage collection pipe can be adjusted by the length of the thread.

[0008] Preferably, the air duct is a flexible tube.

[0009] Preferably, the aquaculture pond is circular or a regular polygon.

[0010] Preferably, each air intake pipe is connected to the same inflation device, or each air intake pipe is equipped with a separate inflation device.

[0011] The beneficial effects of this utility model are:

[0012] (1) By setting up nano-air pipes at the bottom of the aquaculture pond, connecting the nano-air pipes to the air guide pipes, and connecting the air guide pipes to the external air filling device through the air inlet pipes, oxygen is delivered to the nano-air pipes. The nano-air pipes release oxygen into the aquaculture pond, which can not only increase the oxygen in the water, but also generate airflow by releasing oxygen. Under the airflow pressure, impurities in the water gather towards the center of the aquaculture pond where the pressure is relatively low. The impurities first enter the collection pipe through the screen holes on the collection pipe, and then enter the discharge pipe through the reducer pipe and are discharged from the bottom of the aquaculture pond. This can not only ensure the discharge effect and the oxygen content of the aquaculture pond, but also avoid accidentally discharging the fish fry.

[0013] (2) Since the sewage collection pipe and the reducing pipe are connected by threads, the length of the thread can be adjusted to adapt to different water levels, so as to ensure that the lowest point of the screen hole on the sewage collection pipe is flush with the water surface, so that the impurities floating on the water surface can pass through the screen hole and enter the sewage collection pipe smoothly, and the fish fry underwater will not flow out through the screen hole.

[0014] (3) There are no fewer than four air inlets, which are evenly distributed along the aquaculture pond. The corresponding air guide pipes extend to the bottom of the aquaculture pond and work with the nano air pipes fixed at the bottom of the aquaculture pond to gather impurities upward and towards the center of the aquaculture pond from all directions, thereby achieving the collection of impurities.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] like Figure 1-4 As shown, an oxygenation and sewage discharge device for aquaculture ponds includes an aquaculture pond 1. An air inflation device 10 is installed on the outside of the aquaculture pond 1. An air inlet pipe 6 is fixedly installed on the upper part of the aquaculture pond 1, and the air inflation device 10 is connected to the air inlet pipe 6. A valve 9 is installed on the air inlet pipe 6, and an air guide pipe 8 is installed at the other end of the air inlet pipe 6. The air guide pipe 8 is a flexible hose, allowing for easy angle adjustment and connection. A nano-air pipe 2 is fixedly installed at the bottom of the aquaculture pond 1, and is secured to the inner edge of the bottom of the aquaculture pond 1 by clips. The nano-air pipe 2 is connected to the air guide pipe 8. A sewage discharge pipe 3 is located at the center of the aquaculture pond 1, and a reducing pipe 4 is connected above the sewage discharge pipe 3. The other end of the reducing pipe 4 is connected to a sewage collection pipe 5, and the sewage collection pipe 5 has a sieve hole 11 at its upper part.

[0025] The lower end of the air guide pipe 8 is equipped with a T-junction 7, the upper end of which is connected to the air guide pipe 8. The other two ports of the T-junction 7 are connected to nano-air tubes 2. One end of the nano-air tube 2 is connected to a T-junction 7, and the other end is connected to the adjacent port of the adjacent T-junction 7. There can be one or more air inlet pipes 6. When multiple air inlet pipes 6 are set, they are evenly distributed along the breeding pond 1. Each air inlet pipe 6 can be connected to the same inflation device 10, or each air inlet pipe 6 can be equipped with a separate inflation device 10, depending on the actual needs. The air guide pipe 8 corresponding to the air inlet pipe 6 extends to the bottom of the breeding pond 1 and cooperates with the nano-air tubes 2 fixed at the bottom of the breeding pond 1 to gather impurities upward and towards the center of the breeding pond 1 from all directions, thus achieving impurity collection.

[0026] The sludge collection pipe 5 and the reducing pipe 4 are connected by threads. The height of the sludge collection pipe 5 can be adjusted by the length of the thread to adapt to different water levels. This ensures that the lowest point of the screen hole 11 on the sludge collection pipe 5 is flush with the water surface, allowing impurities floating on the water surface to pass through the screen hole 11 and enter the sludge collection pipe 5 smoothly, while the fish fry underwater will not flow out through the screen hole 11.

[0027] By installing nano-air pipes 2 at the bottom of the aquaculture pond 1, and connecting air guide pipes 8 to the nano-air pipes 2, which are connected to an external aeration device 10 via an air inlet pipe 6, oxygen is supplied to the nano-air pipes 2. The nano-air pipes 2 release oxygen into the aquaculture pond 1, which not only increases the oxygen in the water, but also generates airflow by releasing oxygen. Under the pressure of the airflow, impurities in the water gather towards the center of the aquaculture pond 1 where the pressure is relatively low. The impurities first enter the collection pipe 5 through the screen holes 11 on the collection pipe 5, and then enter the discharge pipe 3 through the reducer pipe 4, and are discharged from the bottom of the aquaculture pond 1. This not only ensures the sewage discharge effect and the oxygen content of the aquaculture pond, but also avoids the accidental discharge of fish fry.

[0028] like Figure 5As shown, the breeding pond 1 can also adopt a square structure, and the air inlet pipe 6 can be set at the four corners of the square. The two ends of the nano air pipe 2 are respectively connected to the adjacent interfaces of two adjacent tees 7.

[0029] like Figure 6 As shown, aquaculture pond 1 adopts a square structure, and... Figure 5 The difference is that one end of the nano-air tube 2 is connected to the tee 7, while the other end is directly fixed to the bottom of the breeding pond without being connected to the tee 7, which makes it convenient to modify the existing breeding pond 1.

[0030] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
