Description

Technical Field

[0001] The present invention relates to the field of submerged blowers, in particular to a submerged blower for improving water environment. Background Art

[0002] Dissolved oxygen in water is an indicator of the water's self-purification capacity. When the dissolved oxygen content is too low, it can negatively impact aquatic life and reduce the water's self-purification capacity. Therefore, it's sometimes necessary to manually adjust the dissolved oxygen content. Submerged blowers are often used to increase dissolved oxygen in water.

[0003] For example, the submersible blower for improving the water environment disclosed in authorization announcement number CN217462625U includes a base fixed to the bottom of the water, support columns fixedly connected at both ends of the base, a support plate disposed above the base, a submersible blower body disposed on the upper surface of the support plate, and adjustment brackets for adjusting the position of the submersible blower body disposed at both ends of the support plate, the adjustment brackets slidably connected to the support columns, and the support columns are provided with fixings for fixing the adjustment brackets. By adopting the above technical solution, the beneficial effect of the utility model is that it can reduce the impact of the low water level on the operation of the submersible blower.

[0004] Although the above patent can manually adjust the height of the submerged blower to adapt to changes in the water level, the submerged blower itself is relatively bulky and manual adjustment is very laborious. First, if the device is installed in the center of the water area, the operator still needs the help of a boat to adjust it, which is inconvenient to operate and poses a safety hazard; secondly, although a buffer spring is provided to cushion the body during adjustment, the spring will rust or weaken its elasticity if immersed in water for a long time, affecting its service life; thirdly, there is no synchronous air guide structure at the air outlet. When the height of the fuselage is adjusted, the air guide pipeline needs to be rearranged, which increases the complexity of operation and may cause the risk of gas leakage.

[0031] In this embodiment, the working depth of the submerged blower body 4 is automatically adjusted by the coordinated use of the electric reversing valve 13, the PLC controller 38 and the distance sensor 6, which solves the operational inconvenience of the existing technology requiring manual adjustment of bulky equipment with the help of a ship, and eliminates the safety hazards of the adjustment operation in the center of the water area. The system can automatically complete the lifting and lowering adjustment according to the water level changes without manual intervention, which significantly improves the operational safety and convenience.

[0032] Furthermore, through the sliding sealing cooperation between the air outlet duct 17 of the air guide mechanism and the air outlet pipe 3 7, and the use of the sealing ring 18 and the telescopic waterproof cover 2 19, the automatic adaptation of the air guide pipeline is achieved when the fuselage height is adjusted, which solves the complex operation and gas leakage risk caused by the need to re-lay the pipeline in the existing technology. This design ensures the continuity and sealing of the gas delivery pipeline during the lifting process, greatly simplifying the equipment maintenance work.

[0033] Working Principle: The device is fixedly connected to the base at the bottom of the water via the base 1, allowing the submersible blower body 4 to operate while fully submerged in water. After installation, the floating block 36 remains afloat on the water surface under the counterweight of the counterweight mounting seat 35 and does not completely submerge. The distance sensor 6 monitors the vertical position changes of the floating block 36 in real time. When the water level continues to drop and exceeds the set threshold, the PLC controller 38 first shuts down the submersible blower body 4, then controls the electric reversing valve 13 to switch to a connected state between the outlet pipe 1 14 and the outlet pipe 2 15 and opens the electric valve 27. At this time, the compressed gas in the four piston cylinders 1 20 is collected through the diverter pipe 23 to the five-way valve 24, and then enters the electric reversing valve 13 through the outlet pipe 4 25, the bellows 26 and the outlet pipe 2 15, and is finally discharged from the outlet pipe 1 14, causing the piston rod 1 21 to contract synchronously under the weight of the lifting frame 3. During this process, the air outlet duct 17 of the air guide mechanism slides within the air outlet pipe 3 7 as the lifting frame 3 descends, maintaining an airtight connection. The sealing ring 18 maintains an airtight connection, and the retractable waterproof cover 2 19 contracts synchronously to maintain waterproof performance. When the water level rises and the lift needs to be lifted, the PLC controller 38 controls the electric reversing valve 13 to switch the air outlet pipe 2 15 to a single state and open the electric valve 27. The compressed gas output by the submerged blower body 4 is sequentially diverted through the air outlet pipe 2 15, the bellows 26, the air outlet pipe 4 25, and the five-way valve 24 to the four diversion pipes 23, pushing the piston rod 1 21 to extend and lift the lifting frame 3. At this time, the air outlet duct 17 of the air guide mechanism slides upward within the air outlet pipe 3 7, and the retractable waterproof cover 2 19 extends accordingly. During routine operation, electric reversing valve 13 maintains a single open state for outlet pipe 14. Compressed gas is then delivered to outlet pipe 3 7 through outlet duct 17 of the air guide mechanism after noise reduction by muffler 3 16. Sealing ring 18 ensures a tight seal for the high-pressure gas, and retractable waterproof cover 2 19 provides reliable waterproof protection. Throughout the adjustment process, PLC controller 38 implements closed-loop control using feedback from distance sensor 6, ensuring that submersible blower body 4 always remains at the optimal operating depth.
