Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 shows a schematic structural diagram of the present invention, and referring to fig. 1, for one embodiment of the present invention: the utility model provides a prosthetic oxygenating device in river course, is including setting up water pump 2, venturi mixing tube 3 and the air intake pipe 4 in river course 1, and the delivery port of above-mentioned water pump 2 is intake the end through outlet conduit 5 and above-mentioned venturi mixing tube 3 and is linked to each other, and the one end of above-mentioned air intake pipe 4 is connected on the pipe wall of the end of intaking of venturi mixing tube 3. In this embodiment, take out water through the water pump in the venturi mixing tube, take out the air in the environment simultaneously and mix the oxygenation in the venturi mixing tube, go out the water outlet end blowout through the venturi mixing tube at last to the river in the river oxygenate the organic pollutant of being convenient for to restore aquatic, avoid the organic matter to consume the dissolved oxygen that exists in the aquatic and lead to the water oxygen deficiency, the biological rotten smelly phenomenon production of aquatic.
Further, the diameter of the outlet end of the outlet pipe 5 is gradually reduced and extends into the venturi mixing tube 3. The diameter-changing operation is carried out on the water outlet end of the water outlet pipeline, so that the water flow speed in the water outlet pipeline is accelerated, the gas-liquid mixed water flow is conveniently sprayed out from the venturi mixing pipe, and the whole device is convenient to move.
Further, an annular slide 6 is provided above the waterway 1, and as shown in fig. 2, the water pump 2 is fixed to the slide 6 by a slider 7 and is movable along the slide 6. In order to satisfy the oxygenation treatment of the whole river channel, the oxygenation device is in a moving state, and in order to facilitate the movement of the oxygenation device and enable the oxygenation device to move according to a set direction, an annular slide way is arranged above the river channel, and a water pump is fixed on the slide way through a slide block so as to be added to the oxygenation service range.
Furthermore, in order to make the counter impact force when the gas-liquid mixed water flow is ejected through the water outlet end of the venturi mixing pipe to push the oxygenating device such as a water pump to move along the slide way, the upper end of the air inlet pipe 4 is fixed on the slide way 6 through a second slide block 8, so that the air inlet direction of the air inlet pipe 4 is consistent with the direction of the slide way 6; the water outlet direction of the venturi mixing pipe 3 is consistent with the direction of the slide way 6. After the water pump is started, the water at the bottom of the water pool is pumped up to be depressurized through the Venturi pipe, negative pressure is formed at the mixing pipe, air enters the mixing pipe, is mixed and mixed in the mixing pipe, and then the air is flushed out of the oxygenated water area by the recoil force to push the whole device of the water pump to move forward.
Furthermore, a secondary turbulent flow tube 9 is arranged inside the venturi mixing tube 3, and a plurality of secondary turbulent flow tubes 9 are arranged inside the venturi mixing tube 3 at intervals. And the gas and the liquid in the Venturi mixing pipe are subjected to secondary mixing through the secondary turbulent flow pipe, so that the mixing rate is improved. The secondary turbulent flow pipe is a thin pipe which penetrates through the venturi mixing pipe along the radial direction.
Further, the water inlet of the water pump 2 is connected with a lengthened water inlet pipe 10, and the lowest end of the water inlet pipe 10 is 0.4-0.6 m away from the bottom of the river channel 1. Because the bottom in the river course is attached with sludge, the sludge in the river course is used when the river course is oxygenated, and therefore the water inlet of the water pump is arranged 0.4-0.6 m, preferably 0.5 m away from the bottom of the river course.
Furthermore, a buoyancy tank 11 is disposed outside the water pump 2, the water inlet pipe 10 extends into the river channel 1 from the bottom of the buoyancy tank 11, and the water outlet end of the venturi mixing pipe 3 extends into the river channel 1 from the bottom of the buoyancy tank 11 and faces the water inlet pipe 10. The whole oxygenation device can float on the surface of river water by arranging the buoyancy box body, so that the oxygenation device can move along the track conveniently.
