The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0026] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] like Figure 1-3 The example shown is an embodiment provided by the utility model.

[0029] The embodiment of the utility model provides a water oxygenation device, including: a water tank 10 immersed below the water surface of a water area such as a fish pond or a fish pond, a water inlet 11 connected to the bottom of the water body is provided at the bottom of the water tank 10, and under the action of water pressure, water with low oxygen content at the bottom of the water body will enter the water tank 10 from the water inlet 11. In specific implementation, the position of the water tank 10 can be fixed by setting a fixing frame or the like to prevent the water tank 10 from sinking to the bottom or floating on the surface. An air inlet pipe 20, a plurality of water outlet pipes 30 and a plurality of aeration pipes 40 are respectively connected to the water tank 10, the outer end of the air inlet pipe 20 is the air inlet end, the inner end of the air inlet pipe 20 is the air outlet end, the outer end of the water outlet pipe 30 is the water outlet end, the inner end of the water outlet pipe 30 is the water inlet end, the outer end of the aeration pipe 40 is the air outlet end, and the inner end of the aeration pipe 40 is the air inlet end. When in use, the outer end of the air inlet pipe 20 is connected to an air supply device such as a blower and an air compressor, and the inner end of the air inlet pipe 20 extends into the water body in the water tank 10. The air supply device directly injects the oxygen-containing gas into the water body in the water tank 10 through the air inlet pipe 20, and the oxygen-containing gas entering the water tank 10 constantly contacts the inside and the surface of the water body to dissolve oxygen; the inner end of the water outlet pipe 30 extends into the water body in the water tank 10, and the inner end position of the water outlet pipe 30 is higher than the inner end of the air inlet pipe 20, and the water outlet end of the water outlet pipe 30 is located below the water surface of the water body outside the water tank 10. Under the action of the internal air pressure of the water tank 10, the water body inside the water tank 10 will be pumped out to the water body outside the water tank 10 through the water outlet pipe 30, and the water outlet pipe 30 will produce a siphon effect at its water inlet end when draining water, which can siphon a part of the water that has not yet emerged from the water surface. The oxygen-containing gas is then sucked in by the water tank 10 and then discharged from the water tank 10 in the state of a gas-liquid mixture, and further contacts with the water body outside the water tank 10 to dissolve oxygen; the inner end of the aeration pipe 40 is connected to the inside of the water tank 10, and the inner end of the aeration pipe 40 is located higher than the inner end of the outlet pipe 30. The outlet end of the aeration pipe 40 is located below the water surface of the water body outside the water tank 10. After the oxygen-containing gas inside the water tank 10 emerges from the water body in the water tank 10, it will continue to contact with the surface of the water body inside the water tank 10 to dissolve oxygen. When the accumulated air pressure inside the water tank 10 exceeds the aeration pressure of the aeration pipe 40, it will be released into the water body outside the water tank 10 through the aeration pipe 40. The aeration pipe 40 intermittently exhausts air as the air pressure inside the water tank 10 changes, and the large amount of oxygen-containing bubbles generated will further contact with the water body outside the water tank 10 to dissolve oxygen. During the entire use process, the oxygen-containing gas continuously contacts the water inside the water tank 10, the water surface and the water outside the water tank 10 to dissolve oxygen, which increases the contact time and contact area between the oxygen-containing gas and the water, and improves the dissolved amount and utilization rate of oxygen.

[0030] Furthermore, the air intake pressure of the air intake pipe 20 is greater than or equal to the sum of the aeration pressure of the aeration pipe 40 and the water outlet pressure of the water outlet pipe 30, so that the aeration pipe 40 can continuously and uninterruptedly output the oxygen-containing gas to the outside of the water tank 10, and the water outlet pipe 30 can also continuously output the gas-liquid mixture to the outside of the water tank 10, thereby increasing the discharge amount of the oxygen-containing gas and increasing the total amount of dissolved oxygen in the water.

[0031] Furthermore, a plurality of water outlet pipes 30 are arranged on the side wall of the water tank 10 in an obliquely upward diffusion shape, and a plurality of aeration pipes 40 are arranged horizontally and distributed on the side wall of the water tank 10, so that the oxygen-containing gas and the gas-liquid mixture can be more evenly diffused into the water body around the water tank 10, thereby improving the oxygenation effect.

[0032] Furthermore, the inner end of the air inlet pipe 20 is connected to an air distribution pipe 21, which is horizontally arranged in the water tank 10. The bottom of the air distribution pipe 21 is provided with a plurality of air outlet holes 22 along the length direction. The air outlet holes 22 have a smaller diameter and can produce more and smaller bubbles. The more small bubbles there are, the larger the contact area between the oxygen-containing gas in the bubbles and the water body, and the more sufficient the oxygen dissolved in the water body is, which can further increase the oxygen content of the water body in the water tank 10.

[0033] Furthermore, an inverted air collecting tank 12 is provided inside the water tank 10, and the notch of the air collecting tank 12 is located above the air distribution pipe 21, and the bottom of the air collecting tank 12 is connected to the inner end of the water outlet pipe 30. When a large number of bubbles emerge from the air distribution pipe 21, some of the bubbles will directly rise to the top of the water tank 10, and the other part of the bubbles will first pass through the bottom of the air collecting tank 12 and enter the water outlet pipe 30, so that the water outlet pipe 30 can carry a large number of small bubbles during the water outlet process. The small bubbles emerge from the water outlet end of the water outlet pipe 30, which can have a better oxygenation effect on the water body outside the water tank 10. In addition, an air baffle 13 is provided below the air distribution pipe 21 to block the bubbles emerging from the air distribution pipe 21, shorten the downward movement distance of the bubbles after being ejected, and allow small bubbles to enter the water outlet pipe 30 before they converge into large bubbles, so that the water outlet pipe 30 can discharge water more smoothly, and at the same time, more oxygen-containing gas can enter the water body outside the water tank 10 in the form of small bubbles, thereby increasing the contact area between the two air baffles 13 and the water body outside the water tank 10, thereby improving the oxygenation effect. The air baffle 13 can be provided in two pieces, and the two air baffles 13 are arranged at intervals. While blocking some bubbles, the gap between the two air baffles 13 will not hinder the water inlet of the water tank 10.

[0034] Furthermore, the water inlet 11 is horizontally arranged on two opposite side walls of the water tank 10, and a filter screen 111 is installed outside the water inlet 11 to reduce the silt or debris at the bottom of the water body from entering the water tank 10, avoiding siltation or blockage of the outlet pipe 30, and avoiding the silt at the bottom of the fish pond or fish pool from surging to the upper part of the water body, making the water turbid.

[0035] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents. Any equivalent structure made using the contents of the utility model specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the utility model.
