Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an oxygenation device for aquaculture. Background Technology

[0002] An impeller aerator increases dissolved oxygen in water by agitating and aerating it. In use, the entire aerator is floated in the center of the pond and secured with ropes. During operation, the high-speed rotation of the impeller breaks the surface tension of the water, allowing for greater contact between air and water. As water is thrown into the air, the contact area with the air increases significantly, causing oxygen to dissolve rapidly. Simultaneously, the powerful water flow generated by the impeller's rotation promotes strong convection and mixing, accelerating oxygen diffusion and thus increasing the overall dissolved oxygen level in the water.

[0003] In existing technologies, the impeller of a wheel-type aerator is located within the water body when it rotates, which may harm organisms in the aquaculture area. For example, when shrimp molt, their muscles need to concentrate their strength to contract, and their bodies absorb water and expand to open the old shell. At this time, the shrimp can hardly move on their own. Moreover, due to their small size and weight, when they are molting within the operating range of the wheel-type aerator, they are easily carried upward by the convection generated by the impeller's rotation into the impeller's rotation range, and may be killed by the rotating impeller, causing certain economic losses to farmers.

[0004] Therefore, this application provides an oxygenation device for aquaculture to meet the needs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an aeration device for aquaculture to solve the problem that the upward convection generated by the existing impeller will carry aquatic organisms such as fish and shrimp into its own rotation range, causing damage to the aquatic organisms such as fish and shrimp.

[0006] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0007] An oxygenation device for aquaculture, comprising:

[0008] Electric motor;

[0009] The protective plate is designed in the shape of a funnel, with the tip pointing downwards and the opening upwards. It is located at the bottom of the motor and has an internal interlayer, completely inside the aquaculture pond.

[0010] Several flow holes are provided, which are opened on the protective plate and penetrate the protective plate;

[0011] A sliding element is slidably connected within the protective plate interlayer;

[0012] Filter holes are formed on the sliding member and penetrate the sliding member, and their number and position correspond to the flow holes;

[0013] The filter end is provided with several, each disposed within a corresponding filter hole;

[0014] Several rotating adjustment components are provided, all of which are installed on the top of the protective plate;

[0015] The limiting component is located within the interlayer of the protective plate, and its top is fixed to the bottom of the rotating adjustment component, forming a "Z" shape.

[0016] Preferably, the motor, impeller, and protective plate are coaxial, and the opening area at the top of the protective plate is larger than the rotating working area of ​​the impeller.

[0017] Preferably, the diameter of the filter hole is smaller than the diameter of the flow hole.

[0018] Preferably, the impeller is located at the bottom of the motor and fixedly connected to the output end of the motor, and is used to rotate and stir the surface water of the aquaculture pond to increase the dissolved oxygen content of the water.

[0019] The connecting rods, having no fewer than three, are evenly fixed to the outside of the motor, and use their own buoyancy to drive the impeller to a suitable position.

[0020] The same number of buoyancy balls as the connecting rods are fixed to the end of the corresponding connecting rod away from the motor, and are used to provide buoyancy so that the impeller is in a designated position.

[0021] Preferably, the grooves are formed on the top of the sliding member, and their number and position correspond to those of the limiting member.

[0022] Preferably, the limiting member is configured such that its end away from the rotating adjusting member rotates and enters the top of the slide groove, thus blocking the movement of the sliding member.

[0023] Preferably, the number of fixed connectors is equal to that of the connecting rods, and the bottom of each connector is fixedly connected to the top of the protective plate, while the top of each connector is clamped to the outside of the connecting rods to fix the protective plate.

[0024] Preferably, the fixing connector is configured as a detachable structure.

[0025] This invention provides an oxygenation device for aquaculture. Compared with the prior art, it has the following advantages:

[0026] 1. By setting a funnel-shaped protective plate, the top opening area is larger than the rotating working area of ​​the impeller. When the water flow stirred by the impeller carries small aquatic organisms such as fish and shrimp upwards, the organisms will come into contact with the outside of the protective plate and move away from the impeller along the outside of the protective plate. This avoids being carried into the rotating range of the impeller and being hit and injured, thus protecting the small aquatic organisms.

[0027] 2. By installing a sliding component within the interlayer of the protective plate, and a filter end within the filter hole on the sliding component, the filter end can prevent objects such as aquatic plants and small stones carried by the water flow from contacting the impeller through the flow hole, thus preventing these objects from affecting the normal rotation of the impeller. At the same time, the operator can rotate the adjusting component to move the limiting component out of the top of the sliding component, thereby moving the sliding component. The contact and collision between the sliding component and the protective plate causes the protective plate to vibrate, shaking off the attached mud and other substances, thereby ensuring the cleanliness and normal use of the protective plate, avoiding the impact of impurities on equipment operation, and also avoiding potential harm to aquatic organisms.

[0037] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0038] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0039] Reference Figure 1 - Figure 7 An oxygenation device for aquaculture, comprising:

[0040] Motor 10 must be waterproof;

[0041] The protective plate 20 is set in a funnel shape with the tip pointing downwards and the opening upwards. It is located at the bottom of the motor 10 and has an internal interlayer. It is completely located in the aquaculture pond. The protective plate 20 can be made of materials such as polyethylene and polypropylene, which have waterproof properties, certain strength, and low mass, so as to avoid its mass and buoyancy affecting the stability of the oxygenation equipment.

[0042] The flow holes 21 are provided in several forms, which are opened on the protective plate 20 and penetrate the protective plate 20. They can be set into various shapes such as circles, rectangles, and polygons.

[0043] Sliding member 22 is slidably connected within the interlayer of protective plate 20, and the material used for sliding member 22 is the same as the material used for protective plate 20;

[0044] Filter holes 23 are formed on and through the sliding member 22. Their number and position correspond to the flow holes 21. The shape of filter holes 23 is the same as the shape of flow holes 21.

[0045] The filter end 24 is provided in several forms, each set in a corresponding filter hole 23. The filter end 24 can be set in a circular, square, wedge-shaped or other shapes.

[0046] Several rotating adjustment components 25 are provided and are all installed on the top of the protective plate 20. The rotating adjustment components 25 can be set into cylindrical, square, or other rotatable shapes to facilitate rotation by the staff.

[0047] The limiting member 26 is located in the interlayer of the protective plate 20 and its top is fixed to the bottom of the rotating adjustment member 25. It is in the shape of a "Z". The limiting member 26 can also be set as an "L" shape. When rotating, it can rotate to the top of the sliding member 22 or one side of the top of the sliding member 22.

[0048] The motor 10, impeller 11, and protective plate 20 are coaxial, and the opening area at the top of the protective plate 20 is larger than the rotating working area of ​​the impeller 11. The size of the protective plate 20 can be determined according to the power of the motor 10. When the motor 10 has a larger power and the impeller 11 rotates faster, a larger protective plate 20 is required so that smaller aquaculture organisms such as fish and shrimp can move along the outside of the protective plate 20 to a position further away from the impeller 11, avoiding being carried into its rotation range by the rotating impeller 11 and being injured. When the motor 10 has a smaller power, a smaller protective plate 20 can be used, thereby ensuring that the fish and shrimp are blocked while reducing the contact time between the fish and shrimp and the protective plate 20, and reducing the possibility of injury to the fish and shrimp when in contact with the protective plate 20.

[0049] The diameter of the filter hole 23 is smaller than the diameter of the flow hole 21, which improves the filtering and blocking effect of the filter hole 23 and the filter end 24 inside the filter hole 23 on the flow hole 21.

[0050] Impeller 11 is located at the bottom of motor 10 and is fixedly connected to the output end of motor 10. It is used to rotate and stir the surface water of aquaculture pond to increase the dissolved oxygen content of the water.

[0051] The connecting rod 12, having no fewer than three, is evenly fixed to the outside of the motor 10, and uses its own buoyancy to drive the impeller 11 to a suitable position;

[0052] The number of buoyancy balls 13 is the same as that of the connecting rods 12. They are fixed to the end of the corresponding connecting rod 12 away from the motor 10 and are used to provide buoyancy so that the impeller 11 is in a designated position. The buoyancy balls 13 can be inflated and deflated. The buoyancy balls 13 change their own buoyancy according to the gas inside them, thereby changing the buoyancy of the entire oxygenation equipment.

[0053] The groove 221 is formed on the top of the slider 22. The number and position of the groove 221 correspond to the limiting member 26. The shape of the groove 221 is the same as the trajectory shape of the limiting member 26 moving on the top of the slider 22, which makes it easier for the limiting member 26 to fix the slider 22.

[0054] The limiting member 26 is configured such that after the end away from the rotating adjustment member 25 rotates, it enters the top of the slide groove 221, blocking the movement of the sliding member 22.

[0055] Fixed connectors 27, the same number as connecting rods 12, are fixedly connected to the top of the protective plate 20 at the bottom and clamped to the outside of the connecting rods 12 at the top, for fixing the protective plate 20.

[0056] The fixing connector 27 is designed to be detachable. The fixing connector 27 can be clamped onto the connecting rod 12 by a clip or fixed onto the connecting rod 12 by a waterproof bolt and nut structure.

[0057] Working process and principle: The equipment provides buoyancy through the connecting rod 12 and the buoyancy ball 13, positioning the motor 10 and the connected impeller 11 at a suitable surface water position. The motor 10 drives the impeller 11 to rotate and agitate the surface water, increasing the dissolved oxygen content. Simultaneously, the funnel-shaped protective plate 20, located at the bottom of the impeller 11 and completely within the pond, has a larger opening area at its top than the rotating working area of ​​the impeller 11. When the water flow agitated by the impeller 11 carries smaller aquaculture organisms such as fish and shrimp upwards, they come into contact with the outer side of the protective plate 20 and move upwards along the outer side of the protective plate 20, simultaneously moving away from the impeller 11, thus avoiding being pulled into the rotating area of ​​the impeller 11 and being struck and injured by it. The protective plate 20 has an internal interlayer, within which the sliding member 22 can slide. Its initial position is as follows... Figure 2 and Figure 4 As shown, the sliding member 22 is located at the bottom of the interlayer of the protective plate 20, and the filter end 24 acts as a barrier to prevent objects such as aquatic plants and small stones carried by the water flow from contacting the impeller 11 through the flow hole 21, thus affecting the rotation of the impeller 11. After the aeration equipment has been working for a period of time, the operator can stop the operation of the motor 10, remove the aeration equipment, and rotate the adjusting member 25 to move the limiting member 26 out from the top of the sliding member 22. At this time, the sliding member 22 can move up and down inside the protective plate 20, and the contact and collision between the sliding member 22 and the protective plate 20 during movement causes the protective plate 20 to vibrate, shaking off the mud and other substances attached to the protective plate 20, ensuring the cleanliness of the protective plate 20, and preventing the protective plate 20 from being corroded due to long-term adhesion of mud and other substances, which would affect the use of the protective plate 20.

[0058] When the rotating adjustment component 25 rotates, it drives the bottom "Z"-shaped limiting component 26, causing one end of the limiting component 26 to enter the groove 221 at the top of the sliding component 22, thus fixing the position of the sliding component 22. In addition, the fixing connector 27 fixes the top of the protective plate 20 to the connecting rod 12, ensuring the stability of the overall structure, and ultimately achieving efficient oxygenation while protecting the farmed organisms from harm.

[0059] Therefore, although the present invention has been described herein with reference to specific embodiments thereof, freedom of modification, various changes and substitutions are also within the scope of the above disclosure, and it should be understood that in some cases, certain features of the present invention may be adopted without departing from the scope and spirit of the invention and without corresponding use of other features.
