Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and particularly to an oxygen supply device for a breeding pond. Background Art

[0002] Aquatic animals need sufficient oxygen during their growth process to maintain their life activities and promote metabolism. Especially in a high-density aquaculture environment, the demand for oxygen by aquatic animals is more urgent. If the oxygen content in the breeding pond is insufficient, it will lead to slow growth of aquatic animals, an increase in the feed coefficient, and even the occurrence of diseases and deaths. Therefore, providing a stable and sufficient oxygen supply is one of the keys to the success of aquatic animal breeding.

[0003] After retrieval, the patent with the Chinese patent number CN111642455A discloses an annular oxygen supply device for an aquaculture pond. Its structure includes a base, a motor, a blower, an air inlet pipe, a filter barrel, an air supply pipe, and an oxygen supply structure. The motor is horizontally installed at the upper end of the base, the blower is fixed at the upper end of the base, the air inlet pipe is installed at the left end of the blower, the filter barrel is vertically installed in front of the blower, the air supply pipe is fixed at the upper right end of the filter barrel, and the oxygen supply structure is horizontally installed at the right end of the air supply pipe. The oxygen supply structure includes a connecting pipe, an annular pipe, a branch pipe, and an output structure. The connecting pipe is fixed to the left side of the annular pipe. In the present invention, an output structure is provided at the upper end of the annular pipe, which diffuses horizontally outward, reducing the probability of contact with fish feces, thereby ensuring the clarity of the water quality; a limiting structure is provided at the lower end of the movable structure to send oxygen intermittently, making it less likely to contact the feces that are sinking, thereby preventing the feces from being washed away and ensuring the clarity of the water quality, and better breeding fish. The patent with the Chinese patent number CN111642455A solves the problem that since the oxygen supply device supplies oxygen at the bottom of the pond, the oxygen will be directly sent out from the bottom, and the feces produced by fish sink to the bottom under the influence of gravity, and will contact the vertically sent oxygen during this process, causing the feces to be washed away by the oxygen, and thus making the water quality in the breeding pond turbid and affecting the breeding of fish.

[0004] However, in actual use of the above patent, the bearing is a support and transmission component for the rotating components in the aerator. It is difficult to lubricate the bearing during operation, which will lead to an increase in frictional resistance. During the operation of the aerator, if the frictional resistance of the bearing is large, more energy will be consumed to overcome this resistance, resulting in an increase in energy consumption. Therefore, an oxygen supply device for an aquatic animal breeding pond needs to be proposed. Summary of the Invention

[0005] The object of the present invention is to solve the problem in the prior art that the bearing is a support and transmission component of the rotating component in the aerator. It is difficult to lubricate the bearing during operation, which will increase the frictional resistance.

Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] As Figure 1 - Figure 8 shown, an oxygen supply device for a breeding pond includes a protective box 2. A bearing seat 5 is fixedly installed inside the protective box 2. A bearing body 8 is arranged inside the bearing seat 5. A storage tank 9 for storing lubricating fluid is arranged above the bearing seat 5. A liquid outlet pipe 12 for conveying the lubricating fluid is arranged below the storage tank 9. An opening mechanism for controlling the outflow of the lubricating fluid inside the storage tank 9 is arranged below the storage tank 9. The opening mechanism includes a third motor 29 fixedly installed below the storage tank 9. A universal shaft 28 is arranged at the output end of the third motor 29. The universal shaft 28 is fixedly connected to a threaded rod 27. The threaded rod 27 is threadedly connected to a push rod 14. A fixing disk 13 is fixedly connected to the lower part of the storage tank 9. A first chute 16 is formed at the edge of the fixing disk 13. The first chute 16 is slidably connected to the push rod 14. The push rod 14 is fixedly connected to a turntable 15. A third chute 19 is formed on the surface of the turntable 15. A plurality of baffle plates 17 are slidably connected to the third chute 19. A plurality of second chutes 18 are formed on the surface of the fixing disk 13. The second chutes 18 are slidably connected to the baffle plates 17.

[0033] One side of the bearing seat 5 is fixedly connected with a fixing frame 11. A second motor 26 is fixedly installed at the lower part of the fixing frame 11. The output end of the second motor 26 is provided with a pushing mechanism for pushing lubricating fluid to the surface of the bearing body 8. The pushing mechanism includes a first rotating shaft 20 arranged at the output end of the second motor 26. The first rotating shaft 20 is fixedly connected with a first rotating plate 21. The first rotating plate 21 is movably connected with a second rotating plate 22. The second rotating plate 22 is rotatably connected with a first connecting rod 23. The first connecting rod 23 is rotatably connected with a pushing column 24 for pushing the lubricating fluid to flow from the inside of the liquid outlet pipe 12 to the surface of the bearing body 8. A spring 25 is fixedly connected inside the pushing column 24. One side of the spring 25 away from the pushing column 24 is fixedly connected with the fixing frame 11.

[0034] The universal shaft 28 is rotatably connected with the storage box 9. The turntable 15 is rotatably connected with the fixed disk 13. The first rotating shaft 20 is rotatably connected with the fixing frame 11. The second rotating plate 22 is rotatably connected with the fixing frame 11.

[0035] The pushing column 24 is slidably connected with the fixing frame 11 and is slidably connected with the liquid outlet pipe 12.

[0036] In this embodiment, the bearing seat 5 fixedly installed inside the protection box 2 keeps the bearing body 8 stable. When it is necessary to lubricate the bearing body 8, start the third motor 29 fixedly installed at the lower part of the storage box 9, so that the universal shaft 28 arranged at the output end of the third motor 29 rotates. The universal shaft 28 drives the threaded rod 27 fixedly connected to the side away from the third motor 29 to rotate. The rotation of the threaded rod 27 will cause the push rod 14 connected by threads to move on the threaded rod 27, that is, the push rod 14 will slide inside the first chute 16. When the push rod 14 slides, it will drive the fixedly connected turntable 15 to rotate inside the fixed disk 13. The rotation of the turntable 15 will drive the baffle 17 to slide inside the third chute 19 through the third chute 19 opened on its surface. At the same time, the upper part of the baffle 17 is slidably connected with the second chute 18 opened on the surface of the fixed disk 13, that is, the baffle 17 will slide to the other side of the second chute 18, that is, finally the baffles 17 will move away from each other, so that the lubricating fluid stored inside the storage box 9 flows into the inside of the liquid outlet pipe 12.

[0037] After the lubricating fluid flows into the inner part of the liquid outlet pipe 12, start the second motor 26 fixedly installed at the lower part of the fixing frame 11, so that the first rotating shaft 20 arranged at the output end of the second motor 26 rotates. The first rotating shaft 20 will drive the fixedly connected first rotating plate 21 to rotate. The first rotating plate 21 will drive the second rotating plate 22 to rotate through the protruding block on the upper part of the second rotating plate 22. When the second rotating plate 22 rotates, it will drive the rotatably connected first connecting rod 23 to move. And the first connecting rod 23 and the pushing column 24 are rotatably connected, that is, the second rotating plate 22 will drive the pushing column 24 to slide inside the liquid outlet pipe 12 through the first connecting rod 23, which is convenient for pushing the lubricating fluid flowing into the inner part of the liquid outlet pipe 12 to the surface of the bearing body 8 for lubrication. When the pushing column 24 pushes the lubricating fluid inside the liquid outlet pipe 12 to the surface of the bearing body 8, the spring 25 fixedly connected to the pushing column 24 will be compressed. When the first rotating plate 21 pushes the second rotating plate 22 to rotate half a circle, at this time, under the elastic action of the spring 25, the pushing column 24 will return to its original position, that is, the lubrication of the bearing body 8 can be continuously realized, and the resistance that the device needs to overcome during oxygenation is also reduced accordingly, improving the energy utilization efficiency. For the long-term operating oxygen supply system of the aquaculture pond, this improvement can significantly reduce the operating cost.

[0038] Embodiment 2

[0039] As Figure 1 - Figure 8 As shown, a bracket 1 for keeping the device stable is fixedly installed at the lower part of the protection box 2.

[0040] An oxygenation mechanism is arranged inside the protection box 2, and the oxygenation mechanism is used to increase the dissolved oxygen in the water body.

[0041] The oxygenation mechanism includes a first motor 6 fixedly installed inside the protection box 2. A speed reducer 7 is arranged at the output end of the first motor 6. An impeller shaft 4 is arranged on the side of the speed reducer 7 away from the first motor 6. The impeller shaft 4 penetrates through the protection box 2 and extends to one side of the protection box 2. The impeller shaft 4 penetrates through the center of the bearing body 8. An impeller body 3 for increasing the dissolved oxygen in the water body is arranged on the side of the impeller shaft 4 away from the speed reducer 7.

[0042] A liquid adding port 10 for adding lubricating fluid into the storage box 9 is arranged on one side of the storage box 9.

[0043] In this embodiment, starting the first motor 6 will drive the gearbox 7 provided at the output end to operate. After being decelerated by the gearbox 7, the power is transmitted to the impeller shaft 4. The impeller shaft 4 rotates smoothly under the support of the bearing body 8, that is, ultimately drives the impeller body 3 to rotate continuously. Some or all of the blades on the impeller body 3 are immersed in water. Driven by the first motor 6, the blades rotate at high speed and strike the water surface. The rotation of the blades generates a strong acting force. On the one hand, it presses the surface water into the bottom of the pool, and on the other hand, it pushes the water to flow backward, forming water body flow. When the blades strike the water surface, they will stir air into the water to form dissolved oxygen. At the same time, the water flow generated by the rotation of the blades can also promote the water body flow, enabling the dissolved oxygen to quickly diffuse throughout the water area. The bracket 1 facilitates keeping the device stable during oxygenation, and the liquid filling port 10 facilitates adding lubricating liquid into the storage box 9.

[0044] Meanwhile, an intelligent system is provided inside the protection box 2. When the dissolved oxygen reaches 4.5 mg / L, the device automatically starts for oxygenation and can be controlled via mobile phone. A grain storage bin is provided at the lower part of the protection box 2. When 'feeding' is clicked on the mobile phone, food can be automatically fed. When 'oxygenation' is clicked, the oxygenation pump automatically starts.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
