Description

Technical Field

[0001] This utility model relates to the field of aeration technology, specifically a water flow-driven self-circulating aeration and oxygenation device. Background Technology

[0002] Aeration and reoxygenation of river water is an effective way to purify water.

[0003] In the prior art, an aeration device utilizing water flow force is disclosed in patent announcement number CN220078818U. The device includes an air inlet pipe, an air inlet assembly on the side of the air inlet pipe, an air inlet inclined pipe connected to the air outlet end of the air inlet pipe, a perforated pipe connected to the other end of the air inlet inclined pipe, a plurality of aeration holes on the surface of the perforated pipe, an air outlet inclined pipe at the other end of the perforated pipe, an air outlet pipe at the other end of the air outlet inclined pipe, and a waterproof assembly at the air inlet end of the air inlet pipe.

[0004] While the above scheme has many advantages, it also has the following disadvantages: the ventilation effect is achieved by rotating the fan blades. However, this ventilation method has obvious defects: the drawn-in air does not have enough pressure, resulting in uneven distribution of air bubbles in the water and difficulty in penetrating the water body. This leads to poor aeration effect, making it difficult to meet the demand for efficient oxygenation, and to some extent restricting the growth of aquatic organisms and the improvement of water quality. Utility Model Content

[0005] The purpose of this invention is to provide a water-driven self-circulating aeration and oxygenation device to solve the problem in the prior art where the drawn-in air does not have sufficient pressure, resulting in uneven distribution of bubbles in the water and difficulty in penetrating the water body, thus leading to poor aeration effect and difficulty in meeting the demand for efficient oxygenation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-driven self-circulating aeration and oxygenation device, comprising a rotating shaft, a connecting structure on the outside of the rotating shaft, a waterwheel body fixedly connected to the outside of the rotating shaft, rotating disks fixedly connected to both ends of the rotating shaft, a cylindrical block installed on one side of the rotating disk, a sliding frame slidably connected to the outside of the cylindrical block, an air cylinder on one side of the sliding frame, an air inlet pipe installed on the outside of the air cylinder, an aeration pipe installed at the bottom of the air cylinder, multiple aeration heads installed on the outside of the aeration pipe, a T-shaped piston rod slidably connected inside the air cylinder, the top end of the T-shaped piston rod passing through the top end of the air cylinder and slidably connected to the air cylinder, an L-shaped connecting rod fixedly connected to the outside of the T-shaped piston rod, and the L-shaped connecting rod fixedly connected to the top of the sliding frame.

[0007] Preferably, the connection structure includes a mounting frame, which is rotatably connected to the outside of the rotating shaft, and four fixed support rods are fixedly connected to the top of the mounting frame.

[0008] Preferably, the four fixed support rods are arranged in pairs, and the two pairs of fixed support rods are symmetrically distributed with respect to the vertical center line of the mounting frame. One end of each pair of fixed support rods is fixedly connected to a mounting plate. The symmetrically distributed fixed support rods and mounting plates can provide uniform support force and enhance the overall stability of the device.

[0009] Preferably, both air cylinders are fixedly connected to the mounting frame, and both aeration pipes pass through the mounting frame and are fixedly connected to the mounting frame.

[0010] Preferably, a one-way air inlet valve is installed on the outside of the air inlet pipe, and a one-way air outlet valve is installed on the outside of the aeration pipe, with the one-way air outlet valve located at the bottom of the mounting frame.

[0011] Preferably, two long protrusions are provided on the outer side of the air cylinder. The two long protrusions are symmetrically distributed with respect to the vertical center line of the air cylinder. A protrusion is slidably arranged inside each of the two long protrusions. Both protrusions are fixedly connected to the sliding frame. By providing symmetrically distributed long protrusions and slidably engaged protrusions on the outer side of the air cylinder, the movement of the sliding frame can be precisely guided.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application uses an L-shaped connecting rod to drive a T-shaped piston rod to reciprocate up and down inside the air cylinder. When the T-shaped piston rod moves downward, the air pressure inside the air cylinder increases, and the gas is forced into the aeration pipe through the one-way air outlet valve and discharged from the aeration head, forming bubbles that enter the water to achieve aeration and oxygenation. When the T-shaped piston rod moves upward, a negative pressure is formed inside the air cylinder, and outside air enters the air cylinder through the one-way air inlet valve, completing a self-circulation process. Through this water flow driven method, efficient aeration and oxygenation can be achieved without an additional power source, solving the problems of poor aeration effect and difficulty in meeting the demand for efficient oxygenation, and improving the self-purification capacity and water quality improvement effect of the water body.

[0014] 2. This application uses an installation plate to fix the device in a suitable location in a river or other water body, ensuring stable operation of the device in the water flow. At the same time, the air cylinder and aeration pipe are fixedly connected to the installation frame. The aeration pipe passes through the installation frame and is fixed thereto, ensuring the overall structural stability and operational reliability of the device. This installation and fixing method allows the device to be firmly installed in the water body. Attached Figure Description

[0021] Example: Figure 1 - Figure 4As shown, this utility model provides a technical solution for a water-driven self-circulating aeration and oxygenation device, including a rotating shaft 1. A connecting structure is provided on the outer side of the rotating shaft 1. A waterwheel body 2 is fixedly connected to the outer side of the rotating shaft 1. Rotating discs 6 are fixedly connected to both ends of the rotating shaft 1. A cylindrical block 7 is installed on one side of the rotating disc 6. A sliding frame 8 is slidably connected to the outer side of the cylindrical block 7. An air cylinder 100 is provided on one side of the sliding frame 8. An air inlet pipe 101 is installed on the outer side of the air cylinder 100. An aeration pipe 102 is installed at the bottom of the air cylinder 100. A one-way air inlet valve 111 is installed on the outer side of the air inlet pipe 101. A one-way air outlet valve 122 is installed on the outer side of the aeration pipe 102. The one-way air outlet valve 122 is located at the bottom of the mounting frame 3. Both air cylinders 100... The air cylinder 100 is fixedly connected to the mounting frame 3. Both aeration pipes 102 pass through the mounting frame 3 and are fixedly connected to the mounting frame 3. Multiple aeration heads 103 are installed on the outside of the aeration pipes 102. A T-shaped piston rod 10 is slidably connected inside the air cylinder 100. The top of the T-shaped piston rod 10 passes through the top of the air cylinder 100 and is slidably connected to the air cylinder 100. An L-shaped connecting rod 9 is fixedly connected to the outside of the T-shaped piston rod 10. The L-shaped connecting rod 9 is fixedly connected to the top of the sliding frame 8. Two long protrusions 11 are opened on the outside of the air cylinder 100. The two long protrusions 11 are symmetrically distributed with respect to the vertical center line of the air cylinder 100. A protrusion 110 is slidably arranged inside the two long protrusions 11. Both protrusions 110 are fixedly connected to the sliding frame 8.

[0022] Specifically, the waterwheel 2 in the device rotates under the impact of the water flow, driving the rotating shaft 1 to rotate, thereby causing the two rotating discs 6 to rotate. The cylindrical block 7 slides inside the sliding frame 8. The L-shaped connecting rod 9 drives the T-shaped piston rod 10 to move up and down reciprocally inside the air cylinder 100. When the T-shaped piston rod 10 moves downward, the air pressure inside the air cylinder 100 increases, and the gas is forced into the aeration pipe 102 through the one-way air outlet valve 122 and discharged from the aeration head 103, forming bubbles that enter the water to achieve aeration and oxygenation. When the T-shaped piston rod 10 moves upward, a negative pressure is formed inside the air cylinder 100, and outside air enters the air cylinder 100 through the one-way air inlet valve 111, completing a self-circulation process. Through this water flow driven method, efficient aeration and oxygenation can be achieved without an additional power source, solving the problems of poor aeration effect and difficulty in meeting the demand for efficient oxygenation, and improving the self-purification capacity and water quality improvement effect of the water body.

[0024] Specifically, by installing plate 5, the device can be fixed in a suitable position in a river or other water body to ensure stable operation of the device in the water flow. At the same time, air cylinder 100 and aeration pipe 102 are fixedly connected to the mounting frame 3. The aeration pipe 102 passes through the mounting frame 3 and is fixed thereto, ensuring the overall structural stability and operational reliability of the device. This installation and fixing method allows the device to be firmly installed in the water body.
