Description

Technical Field

[0001] This utility model relates to the field of freshwater fish farming technology, specifically to an oxygenation device for freshwater fish farming ponds. Background Technology

[0002] Freshwater aquaculture refers to the production of raising and breeding aquatic economic animals and aquatic economic plants using ponds, reservoirs, lakes, rivers and other inland waters. It is an important part of the inland aquaculture industry. Existing freshwater aquaculture can also be carried out by building aquaculture ponds. However, this method requires the use of oxygenation equipment to supply oxygen. The equipment cannot be moved to expand the oxygenation range, thus reducing the oxygenation efficiency. There are now patent documents that have improved this.

[0003] For example, Chinese patent CN220897629U discloses an oxygenation device for freshwater fish farming ponds, specifically relating to the field of freshwater aquaculture technology. The device includes a float, with a connecting plate fixedly connected to the left and right ends of the float. An oxygenation structure is fixedly connected to the upper end of the float, a support block is fixedly connected to the front of the upper end of the float, a stirring structure is fixedly connected to the rear end of the support block, a propulsion structure is fixedly connected to the front of the lower end of the float, and a lifting structure is fixedly connected to the middle of the float. This oxygenation device for freshwater fish farming ponds, as described in this utility model, can simultaneously agitate and oxygenate the pond by driving a transmission shaft with a motor, while the meshing motion of gears one and two drives the connecting shaft to rotate. This causes the fan blades to rotate, propelling the device to float and expand the oxygenation range. This design improves the oxygenation efficiency of the device in the farming pond and also enhances its practicality and versatility.

[0004] The equipment described in the above document, while capable of moving the aerator to increase the oxygenation range and adjusting the depth of the oxygen delivery pipe, still has significant drawbacks in practical use, such as:

[0005] The inside of the aquaculture pond will have a large amount of impurities and algae floating on it, and the air outlet pipe is prone to a large amount of buildup in the water, which will block the air outlet and affect the oxygen supply. It will also be inconvenient for staff to clean it later. In addition, the fan blades used to propel the equipment forward can easily cause harm to the fish due to the high-speed rotation of the fan blades and the stirring blades at the bottom.

[0006] Therefore, a freshwater fish farming pond aeration device that is easy to use and highly safe has been designed to address these shortcomings. Utility Model Content

[0007] In view of the shortcomings of the existing technology, this utility model provides an oxygenation device for freshwater fish farming ponds, which solves the problems that existing oxygenation equipment is inconvenient to use and can easily harm fish.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an oxygenation device for a freshwater fish farming pond, comprising a load-bearing top platform, a protective net frame fixedly connected to the bottom of the load-bearing top platform via a bracket, a motor fixedly connected to the top of the load-bearing top platform via a bracket, a rotating rod fixedly connected to the output shaft of the motor via a coupling, the bottom end of the rotating rod passing through the load-bearing top platform and the protective net frame and extending to the inner side of the protective net frame, one end of the rotating rod extending to the inner side of the protective net frame being rotatably connected to the bottom of the inner cavity of the protective net frame via a bearing, and a stirring blade fixedly connected to the surface of the rotating rod and located inside the protective net frame.

[0009] Preferably, both sides of the bottom of the load-bearing platform are fixedly connected to a horizontal seat by a bracket. The top of the horizontal seat is provided with a telescopic opening that extends to the bottom, and several telescopic openings are provided. An air outlet pipe is slidably installed on the inner side of the telescopic opening, and a square air frame is fixedly connected between the top ends of the air outlet pipes on both sides.

[0010] Preferably, oxygen pumps are fixedly connected to both sides of the top of the load-bearing platform, and air guide pipes are fixedly connected to the front and rear of the two oxygen pumps on opposite sides, with the end of the air guide pipe away from the oxygen pump connected to the square air frame.

[0011] Preferably, the front and rear sides of the top of the load-bearing platform are provided with limiting grooves that extend to the bottom. An L-shaped pull plate is slidably installed on the inner side of the limiting groove, and the bottom end of the L-shaped pull plate is fixedly connected to the square air frame. The surface of the rotating rod is fixedly connected to an inclined pressure seat that cooperates with the L-shaped pull plate through a bracket.

[0012] Preferably, the bottom of the transverse seat is fixedly connected to a scraper cylinder that works in conjunction with the air outlet pipe, and the air outlet pipe is in contact with the inner wall of the scraper cylinder. Beneficial effects

[0013] This invention provides an aeration device for freshwater fish farming ponds. Compared with existing technologies, it has the following advantages:

[0014] (1) The oxygenation device for the freshwater fish farming pond is equipped with air outlet pipes installed on both sides of the bottom of the load-bearing top platform using horizontal seats and telescopic openings, and is used in conjunction with L-shaped pull plates and inclined pressure seats. The configuration of these structures can improve the oxygen delivery range and delivery volume through several air outlet pipes. When the inclined pressure seat rotates, it can squeeze the L-shaped pull plate to drive the air outlet pipes to rise and fall continuously, so that the scraper can scrape off the impurities and stains on the surface of the air outlet pipes, ensuring the smooth flow of oxygen and facilitating subsequent cleaning and maintenance.

[0015] (2) The oxygenation device for the freshwater fish farming pond has a protective net frame installed on the bottom of the load-bearing top platform and stirring blades on the surface of the rotating rod. These structures allow the rotating stirring blades to stir the water and increase its contact area with oxygen, thus improving oxygenation. At the same time, the protective net frame can also provide protection to prevent fish from being injured by impact. Attached Figure Description

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figure 1-4This utility model provides a technical solution: an oxygenation device for a freshwater fish farming pond, including a load-bearing top platform 1. A protective mesh frame 2 is fixedly connected to the bottom of the load-bearing top platform 1 via a bracket. A motor 3, a servo motor, is fixedly connected to the top of the load-bearing top platform 1 via a bracket. The output shaft of the motor 3 is fixedly connected to a rotating rod 4 via a coupling. The bottom end of the rotating rod 4 passes through the load-bearing top platform 1 and the protective mesh frame 2 sequentially and extends to the inner side of the protective mesh frame 2. One end of the rotating rod 4 extending to the inner side of the protective mesh frame 2 is rotatably connected to the bottom of the inner cavity of the protective mesh frame 2 via a bearing. The surface of the rotating rod 4 and located within the protective mesh frame 2... A stirring blade 5 is fixedly connected to the inner side. Horizontal seats 6 are fixedly connected to both sides of the bottom of the load-bearing top platform 1 via brackets. A telescopic port 7 extending through to the bottom is opened at the top of the horizontal seat 6, and several telescopic ports 7 are provided. An air outlet pipe 9 is slidably installed on the inner side of the telescopic port 7. A square air frame 8 is fixedly connected between the top ends of the two air outlet pipes 9. The inner side of the square air frame 8 is hollow. Oxygen pumps 10 are fixedly connected to both sides of the top of the load-bearing top platform 1. Air guide pipes 11 are fixedly connected to the front and rear of the opposite side of the two oxygen pumps 10, and the end of the air guide pipe 11 away from the oxygen pump 10 is connected to the square air frame 8.

[0023] Before use, the load-bearing top platform 1 is installed on the inside of the breeding pond using a fixing mechanism. When oxygenation is needed, the motor 3 and two oxygen pumps 10 are started at the same time. When the oxygen pumps 10 are started, oxygen is input into the inside of the square air frame 8 through the air guide pipe 11. Then the square air frame 8 distributes the oxygen through several air outlet pipes 9 for oxygen delivery.

[0024] Furthermore, the front and rear sides of the top of the load-bearing platform 1 are provided with limiting grooves 12 that extend to the bottom. An L-shaped pull plate 13 is slidably installed on the inner side of the limiting groove 12. The top of the L-shaped pull plate 13 will not be completely in contact with the top of the load-bearing platform 1, and there is a space between the L-shaped pull plate 13 and the load-bearing platform 1 that is squeezed by the inclined pressure seat 14. The bottom end of the L-shaped pull plate 13 is fixedly connected to the square air frame 8. The surface of the rotating rod 4 is fixedly connected to the inclined pressure seat 14 that cooperates with the L-shaped pull plate 13 through the bracket. The bottom of the transverse seat 6 is fixedly connected to the scraper cylinder 15 that cooperates with the air outlet pipe 9, and the air outlet pipe 9 is in contact with the inner wall of the scraper cylinder 15.

[0025] At the same time, the start of motor 3 uses rotating rod 4 to drive stirring blade 5 and several inclined pressure seats 14 to rotate slowly. When stirring blade 5 rotates, it will drive water to stir and flow, increasing the contact between water and oxygen. When the inclined pressure seats 14 rotate, they will continuously squeeze L-shaped pull plates 13, thereby causing the L-shaped pull plates 13 on both sides to pull the square air frame 8 and the air outlet pipe 9 to rise and fall. When the air outlet pipe 9 rises and falls, it retracts to the inside of scraper cylinder 15. At the same time, scraper cylinder 15 will also scrape off impurities and algae on the surface of air outlet pipe 9 to prevent blockage.
