Description

Technical Field

[0001] This invention relates to the field of water oxygenation technology, and more particularly to a water oxygenation device. Background Technology

[0002] In the process of raising fish or other aquatic animals, existing ponds or fishponds often need to use aeration devices to provide a certain amount of oxygen to the water in order to increase the oxygen content in the water and provide a good living environment for aquatic animals.

[0003] To increase the oxygen content of the water at the bottom of ponds or fishponds, a national patent (publication number: CN204104538U) discloses a pressurized fine-hole spray aeration device utilizing the bottom water of a fishpond. This device includes a container tank with a main inlet pipe connected to its bottom, leading to the bottom of the pond. Several branch inlet pipes are connected to the main inlet pipe, extending outwards from the bottom. The container tank is also connected to an air inlet pipe, which is connected to an air compressor. Several branch outlet pipes are connected to the container tank and are positioned on the surface of the pond water. The device also includes a microcontroller system connected to the air compressor. This device promotes water flow, thereby achieving a good oxygenation effect.

[0004] However, the device uses an air compressor to inject oxygen-containing gas mainly to increase the air pressure inside the container, so that the water at the bottom can be sprayed out through the outlet branch pipe. After the water level is lowered, the oxygen-containing gas can only contact the surface of the water in the container. Even if a pumping and venting switching device is set up to pump water or vent the container, it is still impossible to continuously inject oxygen-containing gas into the water. This results in a small contact time and contact area between the oxygen-containing gas and the inside of the water, which greatly reduces the oxygenation effect. Summary of the Invention

[0005] In view of this, the present invention provides a water oxygenation device to solve the problem of poor oxygenation effect of existing oxygenation devices.

[0006] To achieve one or more of the above objectives or other objectives, the present invention proposes: a water oxygenation device, comprising: a water tank, an air inlet pipe and a plurality of water outlet pipes, wherein the air inlet pipe and the water outlet pipes are both connected to the interior of the water tank;

[0007] The water tank is submerged below the water surface, and the bottom of the water tank is provided with a water inlet that connects to the bottom of the water body;

[0008] The air inlet pipe is installed through the water tank. The air inlet end of the air inlet pipe is used to connect to the air supply equipment, and the air outlet end of the air inlet pipe extends into the water in the water tank.

[0009] Several water outlet pipes are respectively installed through the water tank, with the inlet end of the water outlet pipe extending into the water in the water tank and the outlet end extending out of the water tank;

[0010] The top of the water tank is also equipped with a water level adjustment mechanism, which is used to adjust the water level in the water tank so that the water level is always higher than the air outlet of the air inlet pipe.

[0011] Preferably, the water level regulating mechanism includes an inlet pipe and a float valve. The float valve is located at the lower end of the inlet pipe, the upper end of the inlet pipe is located in the water outside the water tank, the float valve is located inside the water tank, and the height of the float valve is not lower than the water level inside the water tank.

[0012] Preferably, a plurality of the water outlet pipes are arranged obliquely upward on the side wall of the water tank, and the water outlet end of the water outlet pipe is located in the water body outside the water tank.

[0013] Preferably, the air outlet of the air inlet pipe is connected to a distribution pipe, which is horizontally arranged inside the water tank.

The oxygen-containing gas, in the form of bubbles, fully contacts the water in the tank. After the bubbles rise to the surface, they continue to contact the water surface. Then, the continuously increasing air pressure pumps the water and some of the bubbles out of the tank through the water outlet pipe, which improves the oxygenation effect of the water. Furthermore, the water level in the tank is adjusted by the water level regulating mechanism, so that the air inlet pipe can always inject oxygen-containing gas into the water in the tank, which increases the contact time and contact area between the oxygen-containing gas and the water in the tank, thereby improving the oxygenation effect of the water.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects and not to describe a particular order.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figure 1-3 The image shows an embodiment provided by the present invention.

[0032] This invention provides a water oxygenation device, comprising: a water tank 10, an air inlet pipe 20, and several water outlet pipes 30. The air inlet pipe 20 and the water outlet pipes 30 are both connected to the interior of the water tank 10. Specifically, the water tank 10 is submerged below the water surface of a fishpond, fish pond, or other body of water. The position of the water tank 10 can be fixed by setting up a fixing frame or other means to prevent the water tank 10 from sinking to the bottom or floating to the surface. The bottom of the water tank 10 is provided with an inlet 11 that connects to the bottom of the water body. Under the action of water pressure, water with low oxygen content at the bottom of the water body will enter the water tank 10 through the inlet 11. An air inlet pipe 20 is installed through the water tank 10. The air inlet end of the air inlet pipe 20 is located above the water tank 10 and is used to connect to the air supply equipment. The air outlet end of the air inlet pipe 20 extends downward into the water body inside the water tank 10. By connecting the air supply equipment such as a blower to the air inlet pipe 20, oxygen-containing gas is directly injected into the water body inside the water tank 10, causing the air content inside the water tank 10 to continuously increase. Several water outlet pipes 30 are installed through the water tank 10 and are arranged diagonally upward on the side wall of the water tank 10. The water inlet end of the water outlet pipe 30 extends downward into the water body inside the water tank 10, and the water outlet end extends diagonally upward outside the water tank 10. As the air pressure inside the water tank 10 gradually increases, the water inside the water tank 10 will be sprayed out from the water outlet pipes 30 into the water body outside the water tank 10. A water level regulating mechanism 40 is also provided on the top of the water tank 10. The water level regulating mechanism 40 is used to regulate the water level in the water tank 10 so that the water level is always higher than the air outlet of the air inlet pipe 20. Specifically, the water level regulating mechanism 40 includes an inlet pipe 41 and a float valve 42. The float valve 42 is located at the lower end of the inlet pipe 41, and the upper end of the inlet pipe 41 is located in the water outside the water tank 10. The float valve 42 is located inside the water tank 10, and the height of the float valve 42 is not lower than the water level in the water tank 10. In this embodiment, the float valve 42 can be purchased directly from the market and can control the opening or closing of the water inlet pipe 41 according to the water level. When the air pressure of the air inlet pipe 20 is too high, causing the water level in the water tank 10 to be lower than the height of the float valve 42, the float valve 42 will automatically open, allowing water to enter the water tank 10 from the outside to the inside through the water inlet pipe 41, thereby maintaining the water level in the water tank 10. It can be understood that the height of the float valve 42 is higher than the air outlet of the air inlet pipe 20 and the water inlet of the water outlet pipe 30, which can ensure that the air outlet of the air inlet pipe 20 and the water inlet of the water outlet pipe 30 are always in the water body.

[0033] In the process of using the water oxygenation device provided in this embodiment of the invention, oxygen-containing gas is directly injected into the water through the air inlet pipe 20 with a small diameter. Since most of the gas in the oxygen-containing gas is insoluble in water and cannot be dissolved in water immediately, and the density of the gas is less than that of water, the oxygen-containing gas injected into the water will float to the water surface in the form of bubbles, thereby generating a large number of bubbles. Compared with direct contact with the surface of the water, a large number of spherical or irregular spherical bubbles can contact the water with a larger surface area, thereby greatly increasing the oxygen content of the water inside the water tank 10. After rising to the top of water tank 10, the bubbles re-aggregate and gradually push the water level downwards, continuing to contact the water surface. This process is similar to the principle in existing technology (a pressurized fine-hole spray aeration device utilizing the bottom water of a fishpond (Announcement No.: CN204104538U)) where an air compressor injects oxygen-containing gas to spray water out of the container. However, compared to the aforementioned existing technology, after the oxygen-containing gas pushes the water in the container away from the top wall of the container, it can only contact the water surface and cannot continuously inject into the water. In contrast, the water aeration device provided in this embodiment controls the water level at a suitable height through the water level adjustment mechanism 40, allowing the water to flow downwards. The extended air inlet pipe continuously injects oxygen-containing gas into the water, allowing for large-area and prolonged contact between the gas and the water. Even after escaping from the water, the gas continues to contact the surface, dissolving oxygen and further increasing the contact area. This significantly raises the oxygen content of the water in tank 10. When the air pressure inside tank 10 exceeds the water pressure at the outlet of outlet pipe 30, the oxygenated water is ejected from tank 10 through outlet pipe 30, agitating and oxygenating the water outside. This promotes circulation and exchange between the oxygen-deficient bottom layer and the oxygen-rich upper layer of fishponds and ponds, resulting in overall oxygenation of the water area. Furthermore, some air bubbles are discharged directly from outlet pipe 30 during their ascent, providing additional oxygenation to the water outside tank 10.

[0034] Furthermore, the air outlet of the air inlet pipe 20 is connected to a distribution pipe 21. The distribution pipe 21 can be a common aeration pipe. The distribution pipe 21 is horizontally set inside the water tank 10, so that the air inlet pipe 20 can generate more bubbles in the water, thereby allowing the oxygen-containing gas to contact the water over a larger area. Specifically, the bottom of the distribution pipe 21 has several air outlets 22 distributed along its length. The air outlets 22 have a small diameter, which can generate more and finer bubbles. The more small bubbles there are, the larger the contact area between the oxygen-containing gas in the bubbles and the water, and the more oxygen is dissolved in the water. By setting up the distribution pipe 21, the oxygen content of the water in the water tank 10 can be further increased.

[0035] Furthermore, an inverted air-collecting groove 12 is provided inside the water tank 10. The opening of the air-collecting groove 12 is located above the air distribution pipe 21. The bottom of the air-collecting groove 12 is connected to the water inlet 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 rise directly to the top of the water tank 10, while the other part of the bubbles will first pass through the bottom of the air-collecting groove 12 and enter the water outlet pipe 30. This allows the water outlet pipe 30 to carry a large number of small bubbles during the water discharge 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 outside the water tank 10.

[0036] Furthermore, an air baffle 13 is installed below the air distribution pipe 21. The purpose of the air baffle 13 is to block the air bubbles emerging from the air distribution pipe 21, shorten the downward distance the bubbles travel after being ejected, and allow small bubbles to enter the water outlet pipe 30 before they coalesce into large bubbles, making the water flow from the water outlet pipe 30 smoother. At the same time, it allows more oxygen-containing gas to enter the water outside the water tank 10 in the form of small bubbles, increasing the contact area between the gas and the water outside the water tank 10 and improving the oxygenation effect. Two air baffles 13 can be provided, spaced apart, so that while blocking some air bubbles, the gap between the two air baffles 13 will not obstruct the water inlet of the water tank 10.

[0037] Furthermore, the top of the water tank 10 is connected to a vent pipe 43. The vent end of the vent pipe 43 is connected to the pipe body of the water outlet pipe 30 that extends out of the water tank 10. When the air inlet pipe 20 introduces air into the water tank 10, some of the gas will be directly discharged from the vent pipe 43 and flow into the water outlet pipe 30, and then discharged into the water body outside the water tank 10 along with the water outlet pipe 30. This serves two purposes: firstly, it regulates the air pressure inside the water tank 10; secondly, it directly increases the contact area between the oxygenated air and the water body outside the water tank 10, thereby directly increasing the oxygen content of the water body outside the water tank 10. It is understood that the direction of the outer end of the vent pipe 43 should be approximately the same as the water outlet direction of the water outlet pipe 30, that is, the angle between the air outlet direction of the vent pipe 43 and the water outlet direction of the water outlet pipe 30 should be an acute angle, which can prevent water from the water outlet pipe 30 from flowing back into the water tank 10 through the vent pipe 43. The number of vent pipes 43 is usually only 1-2, which are connected to the two water outlet pipes 30 on different sides of the water tank 10 respectively.

[0038] Furthermore, the inlet 11 is set in a horizontal direction. Specifically, the inlet 11 can be set on opposite sides of the bottom of the water tank 10. A filter screen 111 is installed outside the inlet 11 to reduce the amount of silt or debris at the bottom of the water body entering the water tank 10, avoid causing the outlet pipe 30 to accumulate or become blocked, and also prevent 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 body turbid.

[0039] Obviously, the embodiments described above are merely some embodiments of the present invention, not all embodiments. The accompanying drawings show preferred embodiments of the present invention, but do not limit the patent scope of the present invention. The present invention can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this invention.
