TECHNICAL FIELD
[0001] The utility model relates to water body treatment especially a kind of reoxygenation device gas pipeline fixed assembly of improving the stability of reoxygenation device gas pipeline connection. BACKGROUND
[0002] Reoxygenation device is a kind of product applied to deep water lake, reservoir treatment, which forms pulse bubble piston flow by the sudden release of the air accumulated in pulse air chamber into riser, accelerates the rising, pushes / drives the water body at the bottom of deep water lake from riser to accelerate the rising, until pulse bubble bursts out of riser outlet and diffuses to water surface layer in radial pattern, simultaneously realizes the reoxygenation of upper water body and the vertical flow field circulation mixing between upper and lower water layer, while the water body rich in supersaturated dissolved oxygen in pulse air chamber backflows to the bottom of deep water lake in the forming process of pulse bubble, realizes the reoxygenation of bottom water body.
[0003] Gas compression device built on the shore compresses air, which is delivered to reoxygenation device through gas pipeline for use, and when gas pipeline is laid, it is usually fixed on the fixed block under water by fixed buckle, and compressed air enters reoxygenation device through the bottom of water, but the existing fixed buckle is usually connected rigidly, and when undercurrent surges under water or fish collides, gas pipeline is prone to shaking, and the joint is prone to loosening to cause leakage, which affects the work of reoxygenation device, and meanwhile, gas pipeline collides with fixing member in shaking to cause damage.

[0004] The utility model wants to solve the problem that the existing gas pipeline is fixed on floating block, and the fixing member is connected rigidly, which is prone to damage in strong wind and affects the operation of reoxygenation device, and provides a kind of reoxygenation device gas pipeline fixed assembly for improving the stability of reoxygenation device gas pipeline connection.
[0005] The reoxygenation device gas pipeline fixed assembly of the utility model is fixed on the fixed block under water and connected and fixed with the shore through steel cable, and is characterized in that the fixed assembly is fixed ring, and the fixed ring includes fixed circular ring, damping sheet, damping spring and buffer gasket, the fixed circular ring is composed of two half circular rings connected by upper and lower buckling, the two half circular rings are connected by pivot at one end, and the other end is provided with connecting sheet, and the two connecting sheets are fixed by bolt;A plurality of damping springs are fixed at equal intervals in the inner wall of fixed circular ring, and the bottom end of damping spring is perpendicular to fixed point;Damping sheet is coiled into circular shape, and outer wall is fixed on the top of damping spring;Buffer gasket is fixed on the inner wall of damping sheet.
[0006] The buffer gasket is made of high-elastic polymer material and is fixed on the inner wall of the damping sheet by screws or nails.
[0007] When installing the gas pipeline, the bolts between the two semicircular rings of the fixing ring are removed, then the upper semicircular ring is rotated to open around the rotating shaft, the gas pipeline is placed in the lower semicircular ring, then the upper semicircular ring is reversely rotated to cover the gas pipeline, and the bolts are used to fix and close; when the water surface fluctuates or the wind drives the gas pipeline to shake, the damping spring between the damping sheet and the fixing ring is used to greatly reduce the vibration of the gas pipeline, and then the deformation of the buffer gasket is used to further reduce the vibration of the gas pipeline.
