Description

Technical Field

[0001] This utility model relates to aerators for aquaculture, and more particularly to floats in aerators. Background Technology

[0002] The main structure of an aerator for aquaculture includes a main unit that drives the impeller to rotate and a connecting rod between the main unit and a float. The entire aerator relies on the float to float on the water surface. Most existing aerators of this type use a rigid-shell float, whose volume cannot be changed. An aerator requires at least three floats, which occupy a large amount of space, making transportation inconvenient, especially for long-distance international transport. To solve this problem, existing technology has developed an aerator using a flexible float. The volume of the float in this aerator changes with the inflation pressure; simply releasing the gas inside the float flattens it, solving the problem of the large space occupied by the float and its transportation inconvenience. However, this aerator presents a new problem: the volume of the float is affected not only by the inflation pressure but also by the ambient temperature. For example, the volume of the float changes significantly during two different times of day: under the blazing sun and at a cool night. This change in float volume leads to a change in the float's draft, which in turn causes a change in the depth to which the aerator's impeller is submerged. The impeller's immersion depth needs to be controlled within a certain range; too deep or too shallow a immersion depth will reduce the aerator's energy efficiency. The combined effects of inflation pressure and ambient temperature on the float volume make it difficult for users to accurately determine the impeller's immersion depth, ultimately reducing the aerator's actual energy efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an aerator with a flattenable float. This float solves both the problem of large float size hindering transportation and the difficulty in controlling the impeller's water immersion depth due to the influence of float inflation pressure and ambient temperature. This invention also provides an aerator with a flattenable float.

[0004] This invention is achieved as follows: the compressible float includes an inner liner and an outer shell. The inner liner is an elastic air bladder, and the outer shell is a non-elastic flexible bladder. The inner liner is connected to an air nozzle, and the inner liner is inflated and deflated through the air nozzle.

[0005] In the preferred embodiment, the top of the housing has an opening to which a vertical rigid hollow tube is connected. The rigid hollow tube is provided with an openable cover, and the air nozzle is located inside the rigid hollow tube.

[0006] In the preferred embodiment, the rigid hollow tube is connected to an inner sleeve, and the periphery of the opening of the outer shell is clamped onto the rigid hollow tube by the inner sleeve. The outer shell and the inner sleeve are connected and fixed to the rigid hollow tube by screws.

[0007] In the preferred embodiment, the lower end of the rigid hollow tube is fixed with an umbrella-shaped support, and when the outer shell is expanded to its maximum state, the upper part of the outer shell tightly presses against the umbrella-shaped support.

[0008] The outer shell is made of fiber-reinforced fabric, metal scales, or metal mesh.

[0009] The aerator with a flattenable float according to this utility model includes a main unit that drives the impeller to rotate, a float that floats the aerator on the water surface, and a connecting rod connecting the float and the main unit. In particular, the float is the flattenable float of this utility model, and the connecting rod is firmly connected to the rigid hollow tube. The buoyancy of the float is transmitted to the connecting rod through the rigid hollow tube, thereby making the aerator float on the water surface.

[0010] The advantages of this invention are: 1. Simply releasing the gas from the inner tank flattens the float, solving the problem of conventional hard-shell floats occupying too much space and being inconvenient for transportation. 2. Because the outer shell of the float is a flexible, inelastic bladder, its maximum volume remains constant. Therefore, as long as the inflation pressure of the inner tank is sufficient to tighten the outer shell, the volume of the float is no longer affected by the inflation pressure and ambient temperature. This means that the draft of the float and even the submersion depth of the impeller are no longer affected by the inflation pressure and ambient temperature. It achieves the function of conventional hard-shell floats while solving the problem of existing flexible float aerators having difficulty controlling the submersion depth of the impeller, enabling the aerator to achieve standard energy efficiency under different float inflation pressures and ambient temperatures.

[0014] To facilitate understanding of this utility model, the following embodiments provide a more comprehensive description of the present utility model. The embodiments illustrate implementation methods of the present utility model. However, the present utility model can be implemented in many different forms and is not limited to the implementation methods described in the embodiments.

[0015] See also Figure 1 , Figure 2The compressible float mainly consists of an inner bladder 1 and an outer shell 2. The inner bladder 1 is an elastic air bladder, which can be made of rubber. The outer shell 2 is a non-elastic flexible bladder. As a preferred embodiment, the outer shell 2 is made of fibrous rubber fabric, metal scales, or metal mesh. These materials provide good sun and impact resistance, preventing damage from collisions with fish fins and various planktonic objects in the water. The inner bladder 1 is connected to an air valve 3. The air valve 3 allows for inflation and deflation of the inner bladder 1. Preferably, the air valve 3 is a tire valve. Tire valves are unidirectional and easy to inflate and deflate.

[0016] In the preferred embodiment, the top of the outer casing 2 has an opening to facilitate the insertion and removal of the inner liner 1 from the outer casing 2. An upright rigid hollow tube 4 is connected to the opening. The rigid hollow tube 4 is equipped with an openable cover 5. The air nozzle 3 extends into the rigid hollow tube 4 through the top opening of the outer casing 2. The cover 5 and the rigid hollow tube 4 can be connected by threads. The rigid hollow tube 4 not only protects the air nozzle 3 but also connects to the connecting rod of the aerator. The rigid hollow tube 4 is preferably a cylindrical hollow tube, and can be made of materials such as stainless steel.

[0017] In the preferred embodiment, the rigid hollow tube 4 is connected to the inner sleeve 6, and the periphery of the top opening of the outer shell 2 is clamped onto the rigid hollow tube 4 by the inner sleeve 6. The outer shell 2 and the inner sleeve 6 are connected and fixed to the rigid hollow tube 4 by screws 7. This structure facilitates the replacement of the outer shell 2; the outer shell 2 can be separated from the rigid hollow tube 4 simply by removing the screws 7.

[0018] In the preferred embodiment, an umbrella-shaped support 8 is fixed to the lower end of the rigid hollow tube 4. In the outer shell 2, as... Figure 1 When fully expanded, the upper part of the outer shell 2 tightly presses against the umbrella-shaped support 8. The umbrella-shaped support 8 transfers the buoyancy of the float to the rigid hollow tube 4. This structure greatly reduces the swaying of the outer shell 2 relative to the rigid hollow tube 4, enhances the firmness of the connection between the outer shell 2 and the rigid hollow tube 4, and thus greatly reduces the up-and-down and left-and-right swaying of the aerator caused by the swaying of the float. This allows the aerator impeller to maintain a more accurate water depth, improves the stability of the aerator's operation, and ensures the amount of dissolved oxygen in the water. The connection between the umbrella-shaped support 8 and the rigid hollow tube 4 can be, but is not limited to, welding or integral molding.

[0019] It should be noted that the "inelasticity" of the outer shell described in this utility model is relative to the inner liner. As long as the maximum volume that the outer shell can expand to within the strength range of the outer shell material does not change significantly due to the increase in pressure of the inner liner, the outer shell is an inelastic flexible bladder.

[0020] The aerator with a flattenable float described in this utility model is as follows: Figure 3As shown. The aerator includes a main unit 10 that drives the impeller 9 to rotate, a float 11 that floats the aerator on the water surface, and a connecting rod 12 connecting the float 11 and the main unit 10. The float 11 is a compressible float provided by this invention. A float clamp 13 is fixed to the end of the connecting rod 12, which clamps the rigid hollow tube 4 at the top of the float, thereby fixing the float 11 to the connecting rod 12. The buoyancy of the float 11 is transmitted to the connecting rod 12 through the rigid hollow tube 4 and the float clamp 13, thereby making the aerator float on the water surface. Figure 3 In and Figure 1 , Figure 2 The same number indicates the same component, which will not be elaborated further.

[0021] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of this patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the scope of protection of this utility model. Therefore, the scope of protection of this utility model patent should be determined by the appended claims.
