In order to facilitate an understanding of the invention, the invention will be described more fully and in detail below with reference to the accompanying drawings and preferred embodiments, but the scope of the invention is not limited to the specific embodiments below. It should be particularly noted that in the description of the present invention, it is to be understood that the terms "central", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Example 1:
a water pushing and oxygen increasing device is shown in figures 1-3 and comprises a bracket 11, an impeller 12 which is arranged between two side plates 111 of the bracket 11 and is totally submerged, an impeller cover 13 which is sleeved on the impeller 12, an air duct 14 of which one end extends out of the water surface and the other end is arranged close to the impeller cover 13, and a driving motor 15 which is arranged on the bracket 11 and is used for driving the impeller 12 to rotate; the impeller cover 13 is provided with an opening 131 for the water to enter and exit, and the water flows out from the opening 131 after being rotated by the impeller 12 to obtain kinetic energy. The impeller 12 is a long-axis impeller, and an impeller shaft 121 of the impeller 12 is erected between the two side plates 111; the air duct 14 has a plurality of air ducts 14, and each air duct 14 is distributed between the two side plates 111.
When the water pushing and oxygen increasing device works, the driving motor 15 drives the impeller 12 to rotate through the belt, the impeller 12 stirs the water body, and the water body is discharged from the opening 131 after kinetic energy is obtained by the rotation of the impeller 12. Thereby forming a water suction negative pressure area around the impeller cover 13, and sucking the air in the air duct 14 into the water by using the negative pressure effect, so that the water body near the impeller cover 13 has more dissolved oxygen. And then the impeller 12 continuously pushes the water body with the improved dissolved oxygen into a specified direction. Through the design, when the water pushing work is finished, oxygen in the air is automatically brought into the water by utilizing the fluidics principle, and the oxygen increasing does not need power, so that the purpose of finishing two working effects by one water pushing work power is realized, and a better energy-saving effect is achieved. The impeller 12 is provided with a long-shaft impeller, so that after the water pushing and oxygen increasing device disclosed by the invention acts, a large-span dynamic water flow can be produced, and the water pushing and oxygen increasing device is more suitable for large-scale flowing water body culture. The air ducts 14 can be installed and set in proper quantity on the base plate of the water pushing and oxygen increasing device according to requirements, so that not only is more selectivity provided for the oxygen increasing effect, but also the whole air supplying structure can still normally operate when a certain pipe is damaged or blocked.
In this embodiment, the bracket 11 further includes a front plate 112 and a bottom plate 113 located between the two side plates 111; the bottom plate 113 is located near the opening 131 and is perpendicular to the impeller 12 in the radial direction; a gap 114 for water flow to pass through is reserved between the panel 112 and the bottom plate 113; the bottom plate 113 is provided with a groove 1131 matched with the opening 131. By designing the specific style of the bracket 11 of the water pushing and oxygen increasing device and arranging the panel 112 and the bottom plate 113 near the impeller cover 13, the water body is ensured to flow in the direction beyond the fixed direction after the action of the impeller 12. The bottom plate 113 is located near the opening 131 and is perpendicular to the impeller 12 in a radial direction, so that the water body collides with the bottom plate 113 when flowing out of the opening 131 after being stirred by the impeller 12 and finally flows along the plane of the bottom plate 113.
In this embodiment, a water blocking member 115 is installed at one end of the water outflow side of the panel 112 near the gap 114; the angle of the water deflector 115 relative to the panel 112 is adjustable. The angle of the water retaining piece 115 and the water retaining piece 115 installed on the water outflow side of the water pushing and oxygen increasing device can be changed according to the rotating speed of the impeller 12, so that the flow direction of water flow is more controllable, the normal flow direction of water flow is prevented from being influenced by vortex formed when the water flow flows out of the position near the impeller 12, and the waste of water flow energy is avoided.
In this embodiment, the portion of the impeller housing 13 close to the air duct 14 has a plurality of small housing holes 132, and the wall of the air duct 14 close to the portion of the impeller housing 13 also has a plurality of micro-wall holes 141. When the negative pressure is applied, the air in the tube is divided into small bubbles when reaching the water body through the micro-wall holes 141, so that the oxygen is easier to dissolve into the water body. The impeller cup 13 having a plurality of small cup holes 132 also makes it easier for the highly oxygenated water around the impeller cup 13 to enter the impeller cup 13.
