[0002] An aerator is a device that uses a power source such as an electric motor or a diesel engine to drive the working parts, so that the "oxygen" in the air can be quickly transferred to the aquaculture water. It can comprehensively utilize physical, chemical and biological functions. It can not only solve the problem of fish floating due to lack of oxygen in pond aquaculture, but also eliminate harmful gases, promote water convection exchange, improve water quality conditions, reduce feed coefficient, and increase fish pond activity and primary productivity, thereby increasing stocking density, increasing the feeding intensity of aquaculture objects, promoting growth, and significantly increasing per mu yield, fully achieving the purpose of increasing aquaculture income. Nowadays, there are many types of oxygenation equipment, and the effects of use are very different. For example, the prior art: CN106135113A, an aquaculture oxygenator, includes a motor and a returnless impeller connected to the motor, the motor can drive the returnless impeller to rotate as a whole, the returnless impeller includes a second shell with a accommodating space, and a centrifugal cavity formed in the accommodating space and capable of lifting water, the centrifugal cavity has a relative water inlet and a water outlet, the water inlet is located at the bottom end of the second shell, or the space from the water inlet to the bottom end of the second shell is an unobstructed hollow cavity.

[0003] There are other existing technologies:

[0004] CN105010219A, aquaculture oxygenator;

[0005] CN109832223A, aquaculture oxygenator.

[0006] The above-mentioned prior arts all achieve oxygenation of pond water by extracting water from the pond, breaking it up and spraying it out, thereby increasing the contact area between water and air and allowing oxygen in the air to dissolve into the water. Although this method is simple and effective, the above-mentioned prior arts, when extracting pond water, ignore the fact that the water in the pond is not just water, but also contains fish, algae and even some floating garbage. Once these impurities are pumped into the equipment, they will directly contact and collide with the rotating mechanism without any protection, which can easily damage the equipment. Therefore, the entire equipment needs to be protected to avoid the above situation. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1 The utility model provides a technical solution: an aquaculture oxygenation device.

[0023] Among them, a protective cover 2 is provided on the top of the outer shell 1, a motor 3 is provided inside the protective cover 2, a baffle 4 is provided at the bottom of the motor 3, a hole is provided in the center of the baffle 4, a blade rotating shaft 5 is installed through the hole, a blade 6 is fixedly connected to the outside of the blade rotating shaft 5, a propeller rotating shaft 8 is provided at the bottom of the blade rotating shaft 5, and a blade 6 is fixedly connected to the outside of the propeller rotating shaft 8, a water outlet window 7 is provided at the top of the outer side of the outer shell 1, a base 11 is provided at the bottom of the water outlet window 7, the base 11 is fixedly connected to the outside of the outer shell 1, a fixing plate 12 is installed on the other side of the base 11, a connecting rod 13 is fixedly connected to the other end of the fixing plate 12, a connecting piece 14 is provided at the other end of the connecting rod 13, a floating plate 15 is provided at the bottom of the connecting piece 14, and a filter screen 10 is provided at the bottom of the outer shell 1.

[0024] In this embodiment, the protective cover 2 plays a waterproof role to prevent moisture from affecting the internal motor 3. The motor 3 is started to drive the blade rotating shaft 5 and the propeller rotating shaft 8 to rotate. The propeller rotating shaft 8 drives the propeller 9 to rotate, and the water flow at the bottom is stirred by rotation. Part of the water flow is brought up and enters the blade 6 above. The blade 6 rotates through the blade rotating shaft 5. Under the action of centrifugal force, it is pushed upward by the blade 6 along the inner wall of the outer shell 1 and finally passes through the water outlet window 7 and is thrown out of the equipment. The water is decomposed into water mist and fully contacts with the air. The oxygen in the air is dissolved in the water mist. Finally, the water mist falls back to the water surface with oxygen, so that the oxygen content in the pond is increased.

[0025] The surface of the filter screen 10 is uniformly provided with diamond-shaped holes, and the filter screen 10 is fastened to the housing 1 by fasteners.

[0026] In this embodiment, the diamond-shaped holes are low in height and long in length, which can prevent fish from accidentally entering the device. At the same time, they can also isolate some larger debris, algae, etc., and prevent them from being stirred into the rotating shaft of the device and causing damage to the device.

[0027] The floating plate 15 is made of foam plastic, the floating plate 15 is fastened to the connecting plate 14 by fasteners, and the fixing plate 12 is fastened to the base 11 by fasteners.

[0028] In this embodiment, the floating plate 15 provides buoyancy for the entire device to ensure that the device will not sink into the water. Fasteners are used to lock the floating plate 15 and the connecting rod 13, which is convenient for disassembly and replacement. When the device is not in use, the fasteners on the connecting rod 13 are removed, and the floating mechanism can be folded up to minimize the occupied area of ​​the device.

[0029] The bottom of the water outlet window 7 is higher than the blades 6 , and the water outlet window 7 is rectangular and evenly distributed on the outside of the housing 1 .

[0030] In this embodiment, water flows into the blades 6. Since the blades 6 are inclined, water is given centrifugal force to move outward after contacting the blades 6. By contacting the inner wall of the shell 1, more water is accumulated and the water continues to move upward. Finally, the water reaches the water outlet window 7 and is thrown out. The evenly distributed rectangular water outlet windows 7 can maximize the use of the number and area of ​​the water outlet windows 7.

[0031] The bottom height of the floating plate 15 is lower than the top height of the propeller 9 .

[0032] In this embodiment, when the device is located in water, a part of the propeller 9 can be exposed out of the water, so that when the propeller 9 rotates, a large amount of water splashes upward, and a large amount of water splashes can fall on the blades 6, thereby participating in the circulation.

[0033] Working principle: the equipment floats on the water surface through the floating board 15, and a part of the propeller 9 is immersed in the water. The motor 3 is started to drive the blade rotating shaft 5 and the propeller rotating shaft 8 to rotate. The propeller rotating shaft 8 drives the propeller 9 to rotate, and the water flow at the bottom is stirred by rotation. A part of the water flow is brought up and enters the blade 6 above. The blade 6 rotates through the blade rotating shaft 5, and is pushed upward by the blade 6 along the inner wall of the shell 1 under the action of centrifugal force, and finally passes through the water outlet window 7 and is thrown out of the equipment. The water is decomposed into water mist and fully contacts with the air. The oxygen in the air is dissolved in the water mist. Finally, the water mist falls back to the water surface with oxygen, so that the oxygen content in the pond is increased. The filter net 10 at the bottom can prevent fish, algae and other debris from being involved in the equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
