Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, and in particular to an oxygen supply device for deep-sea aquaculture cages. Background Technology

[0002] Deep-sea aquaculture cages are devices used for aquaculture in deeper waters. They mainly consist of a frame system, netting, a fixing system, and supporting facilities. Through the interaction of the fixing platform and the characteristics of the cage itself, the cage is lowered to a limited underwater depth. The oxygen supply device is used to increase the dissolved oxygen content of the seawater within the cage, ensuring the respiratory needs of the cultured organisms. Its core function is to efficiently supplement the water with oxygen through various technologies. Typically, air is injected into the water using oxygen pumps, air supply pipes, and air distribution pipes to solve the problem of insufficient oxygen in the aquaculture area. However, due to waves and the corrosive nature of seawater in the aquaculture area, the oxygen supply device must not only prevent seawater intrusion but also be breathable to allow outside air to enter the oxygen pump. Existing technologies lack sufficient wave protection. For example, Chinese patent CN218635090U describes an oxygen supply device that simply installs the oxygen supply equipment on a floating board. When waves come, seawater splashes into the oxygen supply equipment, causing it to be damaged and affecting the oxygen supply to the aquaculture cage. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides an oxygen supply device for deep-sea aquaculture cages, which prevents seawater from entering the air pump due to waves, while also ensuring that air can smoothly enter the air pump to ensure a stable supply of oxygen.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] An oxygen supply device for a deep-sea aquaculture cage includes a float, an oxygen pump, a first air supply pipe, and an air distribution pipe. The float has a cavity, and the oxygen pump is installed inside the cavity. The upper side of the cavity is connected to the outside through an air intake channel. The oxygen pump is connected to the air distribution pipe through the first air supply pipe. The air distribution pipe has several air outlets. The air intake channel is above the sea level and includes a downwardly inclined section and an upwardly inclined section connected in sequence. The bottom of the downwardly inclined section and the upwardly inclined section have several drainage channels.

[0006] Furthermore, the side of the float is provided with an inverted L-shaped shield, which is fixed above the air inlet of the upper inclined part and covers the air inlet of the upper inclined part.

[0007] Furthermore, the side of the float is provided with a wave-proof groove, the upper end of the wave-proof groove is flush with the bottom of the inverted L-shaped shield, and the top of the wave-proof groove is a downward curved arc.

[0008] Furthermore, the float is composed of a left float and a right float, and an adhesive layer is provided between the left float and the right float.

[0009] Furthermore, the bottom of the float is provided with a through hole, through which the first gas supply pipe passes, and an adhesive layer is provided between the first gas supply pipe and the through hole.

[0010] Furthermore, it also includes an intercepting net, which has connectors around its perimeter for connecting to aquaculture cages. The intercepting net includes an outer frame and several V-shaped intercepting net strips, with a strip-shaped hole in the middle of each V-shaped intercepting net strip. The sides of several V-shaped intercepting net strips are connected in series.

[0011] Furthermore, the diameter of the mesh openings in the V-shaped intercepting mesh is larger than the diameter of the air outlet.

[0012] Furthermore, tension ropes are provided on both sides of the V-shaped interception net strip and on both sides of the air outlet, and the tension ropes are connected to the outer net frame.

[0013] Furthermore, the lower end of the connector is fixedly connected to the outer mesh frame, and the upper end of the connector is provided with a hook.

[0014] The beneficial effects of this invention are as follows: During the flow of external air, the air needs to flow downwards from the upper end of the upper inclined section into the lower inclined section, and then downwards from the lower end of the lower inclined section into the cavity. When waves cause seawater to enter through the upper inclined section, because seawater is denser than air, it is discharged from the bottom of the upper and lower inclined sections through the drainage channel, returning to the ocean and preventing seawater from entering the cavity. This invention is well adapted to the working environment at sea, preventing seawater from entering the air pump due to waves, while also ensuring smooth airflow into the air pump and a stable oxygen supply.

[0022] Example 1

[0023] Please refer to the attached document. Figure 1This application provides an oxygen supply device for deep-sea aquaculture cages, including a float 1, an oxygen pump 2, a first air supply pipe 3, and an air distribution pipe 4. The float 1 has a cavity, within which the oxygen pump 2 is housed. The upper side of the cavity is connected to the outside via an air intake channel 5. The oxygen pump 2 is connected to the air distribution pipe 4 via the first air supply pipe 3. The air distribution pipe 4 has several air outlets. The air intake channel 5 is above sea level and includes a downwardly inclined portion 20 and an upwardly inclined portion 21 connected in sequence. Several drainage channels 6 are provided at the bottom of the downwardly inclined portion 20 and the upwardly inclined portion 21. The float 1 floats on the sea surface. The oxygen pump 2 is housed within the cavity of the float 1 to prevent seawater corrosion of the oxygen pump 2. When the oxygen pump 2 is working, it pumps air into the first air supply pipe 3 and the air distribution pipe 4. Finally, the gas is discharged from the air outlets on the air distribution pipe 4, thereby supplying oxygen to the deep-sea aquaculture cages. The oxygen pump 2 uses air sourced from the atmosphere, which enters the cavity through the air intake channel 5. As the outside air enters the cavity, it first passes through the upper inclined section 21, then the lower inclined section 20, and finally enters the cavity. Therefore, the outside air flows downwards from the upper end of the upper inclined section 21 into the lower inclined section 20, and then downwards from the lower end of the lower inclined section 20 into the cavity. When waves cause seawater to enter through the upper inclined section 21, because seawater is denser than air, it is drained through the drainage channel 6 at the bottom of the upper and lower inclined sections 21 and finally discharged back into the ocean, preventing seawater from entering the cavity. This invention effectively adapts to the working environment at sea, preventing seawater from entering the pump due to waves, while also ensuring a smooth flow of air into the pump, guaranteeing a stable oxygen supply.

[0024] Specifically, the float 1 has an inverted L-shaped shield 7 on its side. The inverted L-shaped shield 7 is fixed above the air inlet of the upper inclined part 21 and covers the air inlet of the upper inclined part 21. The inverted L-shaped shield 7 is used to block seawater, further preventing waves from entering the cavity and ensuring the stable operation of the oxygenation pump 2.

[0025] Specifically, the float 1 has a wave-damping groove 8 on its side. The upper end of the wave-damping groove 8 is flush with the bottom of the inverted L-shaped shield 7, and the top of the wave-damping groove 8 is a downward-curved arc. When waves crash against the side of the float 1, seawater is stirred up along the wave-damping groove on the side of the float 1. When it reaches the top of the wave-damping groove, it flows downward along the arc-shaped structure, further reducing the possibility of seawater entering the oxygen pump 2 and ensuring the stable operation of the oxygen pump 2.

[0026] Specifically, the float 1 is composed of a left float 91 and a right float 101, with an adhesive layer 11 between them. The left float 91 and the right float 101 are bonded together by the adhesive layer 11 to form a whole. Half of the cavity, air intake channel 5, and drainage channel 6 are located on the left float 91, and the other half are located on the right float 101. The left float 91 and the right float 101 are bonded together after the oxygen pump 2 is installed, which facilitates installation and provides good waterproof performance.

[0027] Specifically, the bottom of the float 1 is provided with a through hole 12, through which the first gas supply pipe 3 passes. An adhesive layer 11 is provided between the first gas supply pipe 3 and the through hole 12. By using the adhesive layer 11 to bond the first gas supply pipe 3, the stability of the first gas supply pipe 3 is improved, and the sealing performance is improved, preventing water from entering the cavity through the through hole 12.

[0028] Example 2

[0029] Referring to the accompanying drawings, the difference between this embodiment and Embodiment 1 is that it also includes an intercepting net 13. The intercepting net 13 has connectors 14 around its perimeter for connecting to the aquaculture cage. The intercepting net includes an outer frame 15 and several V-shaped intercepting net strips 16. Each V-shaped intercepting net strip has a strip-shaped hole 17 in its center, and the sides of several V-shaped intercepting net strips 16 are connected in series. The intercepting net 13 is fixed to the bottom of the aquaculture cage via the connectors 14. When gas discharged from the air distribution pipe 4 flows upward, it is obstructed by the intercepting net 13, thus slowing down the upward and downward movement of the gas and increasing the time the gas stays in the seawater. This allows more time for oxygen to dissolve in the seawater, improving the oxygenation effect. The outer frame 15 of the intercepting net 13 provides fixation, improving the stability of the intercepting net 13. The strip-shaped holes 17 at the bottom of the V-shaped intercepting net strips 16 allow fish feces to pass through, preventing fish feces from being intercepted by the intercepting net 13.

[0030] Specifically, the diameter of the mesh openings in the V-shaped intercepting mesh 16 is larger than the diameter of the air outlet. This slows down the upward movement of the gas. Since the diameter of the bubbles is smaller than the diameter of the mesh openings, the bubbles can pass through the mesh openings, preventing them from being intercepted.

[0031] Specifically, tension ropes 18 are provided on both sides of the V-shaped intercepting net strip 16 and on both sides of the air outlet, and the tension ropes 18 are connected to the outer net frame 15. By tightening the V-shaped intercepting net strip 16 with the tension ropes 18, the net surface of the V-shaped intercepting net strip 16 is kept in a taut state, which is beneficial for intercepting air bubbles.

[0032] Specifically, the lower end of the connector 14 is fixedly connected to the outer mesh frame 15, and the upper end of the connector 14 is provided with a hook 19. The outer mesh frame 15 is fixed to the bottom of the breeding box by hanging the aquaculture net box through the hook 19.

[0033] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
