Description

Technical Field

[0001] The present invention relates to an aerator for aquaculture, and particularly to the floating balls of the aerator. Background Art

[0002] The main structure of an aerator for aquaculture includes a main machine that drives the impeller to rotate, and a connecting rod connected between the main machine and the floating balls. The entire aerator floats on the water surface relying on the floating balls. Most existing such aerators adopt floating balls with a hard shell structure, and the volume of the floating balls cannot be changed. At least three floating balls need to be configured for one aerator, and the space occupied by the floating balls is relatively large, which is not conducive to transportation, especially not conducive to international long-distance transportation. To solve this problem, there has emerged in the prior art an aerator that uses flexible floating balls. The volume of the floating balls of this aerator changes with the change of the inflation pressure. As long as the gas in the floating balls is discharged, the floating balls can be flattened, solving the problem that the large space occupied by the floating balls is not conducive to transportation. However, this kind of aerator has new problems: the volume of the floating balls is not only affected by the inflation pressure, but also affected by the ambient temperature. For example, the volume of the floating balls will change significantly at two different time periods, when the sun is shining brightly and at night when it is cool. The change in the volume of the floating balls will cause the draft depth of the floating balls to change, and further cause the immersion depth of the impeller of the aerator to change. The immersion depth of the impeller needs to be controlled within a certain range. If it is too deep or too shallow, the energy efficiency of the aerator will be reduced. The influence of the inflation pressure and the ambient temperature on the volume of the floating balls at the same time makes it difficult for users to grasp the immersion depth of the impeller, and ultimately reduces the actual use energy efficiency of the aerator. Summary of the Invention

[0003] The object of the present invention is to provide a collapsible floating ball for an aerator, which can not only solve the problem that the large space occupied by the floating ball is not conducive to transportation, but also solve the problem that it is difficult to grasp the immersion depth of the impeller of the aerator due to the influence of the inflation pressure and the ambient temperature of the floating ball. The present invention also provides an aerator with collapsible floating balls.

[0004] The present invention is implemented as follows: The collapsible floating ball includes an inner bladder and an outer shell. The inner bladder is an elastic airbag, the outer shell is a non-elastic flexible bladder, the inner bladder is connected with a nozzle, and the inner bladder is inflated and deflated through the nozzle.

[0005] As the best implementation mode, the top of the outer shell has an opening, the opening is connected with a vertical rigid hollow tube, the rigid hollow tube is provided with an openable protective cover, and the nozzle is located in the rigid hollow tube.

[0006] As the best implementation mode, the rigid hollow tube is connected with an inner sleeve, the periphery of the opening of the outer shell is clamped on the rigid hollow tube by the inner sleeve, and the outer shell and the inner sleeve are connected and fixed to the rigid hollow tube through screws.

[0007] As a preferred embodiment, an umbrella-shaped supporting seat is fixed to the lower end of the rigid hollow tube, and in the state where the outer shell expands to the maximum, the upper part of the outer shell tightly presses against the umbrella-shaped supporting seat.

[0008] The material of the outer shell is fiber gum cloth, metal scales or wire mesh.

[0009] The floatable aerator of the present invention includes a main engine for driving the impeller to rotate, a float for floating the aerator on the water surface, and a connecting rod connected between the float and the main engine. In particular, the float is the collapsible float of the present invention, the connecting rod is firmly connected to the rigid hollow tube, and the buoyancy received by the float is transmitted to the connecting rod through the rigid hollow tube, thereby floating the aerator on the water surface.

[0010] The advantages of the present invention are as follows: 1. As long as the gas in the inner bladder is released, the float can be flattened, solving the problem that the conventional hard-shell float occupies a large space and is not conducive to transportation. 2. Since the outer shell of the float is an inelastic flexible bladder and its maximum volume is constant, as long as the inflation pressure of the inner bladder is sufficient to tighten the outer shell, the volume of the float will no longer be affected by the inflation pressure of the float and the ambient temperature, so that the draft depth of the float and even the water entry depth of the impeller will no longer be affected by the inflation pressure of the float and the ambient temperature, achieving both the functions of the conventional hard-shell float and solving the problem that it is difficult to control the water entry depth of the impeller of the existing flexible float aerator, enabling the aerator to reach the standard energy efficiency under different inflation pressures of the float and ambient temperatures.

[0012] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below through embodiments. The embodiments give the implementation manners of the present invention. However, the present invention can be implemented in many different forms and is not limited to the implementation manners described in the embodiments.

[0013] See also Figure 1 、 Figure 2The flattenable float is mainly composed of an inner liner 1 and an outer shell 2. The inner liner 1 is an elastic air bag and can be made of rubber. The outer shell 2 is an inelastic flexible capsule. As the best embodiment, the outer shell 2 is made of fiber colloid cloth, metal scales or metal wire mesh. The outer shell made of these materials has good sun resistance and collision resistance, which can prevent the outer shell 2 from being damaged by collision with the wing tip of the fish and various floating objects in the water. The inner liner 1 is connected to an air nozzle 3. The air nozzle 3 can be used to inflate and deflate the inner liner 1. The air nozzle 3 is preferably a tire air nozzle. The tire air nozzle is unidirectional and easy to inflate and deflate.

[0014] As the best embodiment, the top of the shell 2 is provided with an opening, which is convenient for the liner 1 to be placed into the shell 2 or taken out from the shell 2 through the opening. The opening is connected to an upright rigid hollow tube 4. The rigid hollow tube 4 is provided with an openable protective cover 5. The air nozzle 3 extends into the rigid hollow tube 4 from the top opening of the shell 2. The protective 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 has the function of connecting with the connecting rod of the aerator. The rigid hollow tube 4 is preferably a cylindrical hollow round tube, which can be made of materials such as stainless steel.

[0015] As a best embodiment, the rigid hollow tube 4 is connected to the inner sleeve 6, the periphery of the top opening of the outer shell 2 is clamped on the rigid hollow tube 4 by the inner sleeve 6, and the outer shell 2 and the inner sleeve 6 are connected and fixed to the rigid hollow tube 4 by screws 7. This structure is convenient for replacing the outer shell 2, and the outer shell 2 can be separated from the rigid hollow tube 4 by simply removing the screws 7.

[0016] As the best embodiment, an umbrella-shaped support seat 8 is fixed to the lower end of the rigid hollow tube 4. Figure 1 In the state shown as expanded to the maximum, the upper part of the shell 2 is tightly pressed against the umbrella-shaped support seat 8. The umbrella-shaped support seat 8 transmits the buoyancy of the float to the rigid hollow tube 4. This structure can greatly reduce the shaking of the shell 2 relative to the rigid hollow tube 4, enhance the firmness of the connection between the shell 2 and the rigid hollow tube 4, thereby greatly reducing the up and down and left and right shaking of the aerator due to the shaking of the float, so that the impeller of the aerator maintains a more accurate water entry depth, improves the stability of the aerator and ensures the amount of dissolved oxygen in the water. The connection method of the umbrella-shaped support seat 8 and the rigid hollow tube 4 can be, but is not limited to, welding or integral molding.

[0017] It should be noted that the shell described in the present invention is "inelastic" relative to the liner. As long as the maximum volume that the shell can expand to is within the tolerable range of the shell material strength, the shell is an inelastic flexible capsule as long as the maximum volume that the shell can expand to does not change significantly due to the increase in the liner pressure.

[0018] The aerator with a flattenable floating ball according to the present invention is as follows Figure 3As shown in the figure. The aerator includes a main machine 10 that drives the impeller 9 to rotate, a floating ball 11 that floats the aerator on the water surface, and a connecting rod 12 connected between the floating ball 11 and the main machine 10. The floating ball 11 is a collapsible floating ball provided by the present invention. A floating ball clamp 13 is fixed at the end of the connecting rod 12, and the floating ball clamp 13 clamps the rigid hollow tube 4 at the top of the floating ball, thereby fixing the floating ball 11 on the connecting rod 12. The buoyancy force received by the floating ball 11 is transmitted to the connecting rod 12 through the rigid hollow tube 4 and the floating ball clamp 13, so as to float the aerator on the water surface. Figure 3 in the same as Figure 1 , Figure 2 The same numbers represent the same components and will not be described in detail again.

[0019] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
