Description

Technical Field

[0001] This utility model relates to the field of aerator technology, specifically to a float for an impeller aerator and an aerator having the float. Background Technology

[0002] Aerators are used in aquaculture to increase the dissolved oxygen concentration in water. Their main technical effects are: maintaining a suitable dissolved oxygen concentration in the water to meet the physiological oxygen requirements of farmed fish; and simultaneously inhibiting the proliferation of anaerobic bacteria in the water, thereby preventing water quality deterioration from threatening the fish's living environment.

[0003] Impeller-type aerators are a commonly used type in this field. Their structure mainly includes an impeller, a drive motor, and a float. The impeller is the core aerator component, the drive motor is the power source, and the float is the suspension mechanism. The impeller-type aerator is suspended above the water surface by connecting the float to a support rod. While existing floats are relatively lightweight, their large size and fixed shape result in low space utilization during transportation, significantly increasing transportation costs and making loading, unloading, and transportation inconvenient. Furthermore, they require substantial storage space in both production and user sites, hindering production organization and user storage, thus significantly increasing production costs. Utility Model Content

[0005] The technical solution of this utility model for the float ball used in aerators is as follows:

[0006] A float for an impeller-type aerator includes a float cover, a neck, an upper part, and a lower part, wherein the neck and the upper part are integrally formed; a third connecting part is provided on the inner side of the float cover, a first connecting part is provided on the inner side of the neck along the neck opening, and a second connecting part is provided on the inner side of the lower part; the first connecting part can be connected to the second and third connecting parts respectively; the upper part and the lower part are fitted together; a plurality of guide parts and a first fitting part are provided on the outer periphery of the upper part, with an opening between the guide parts and the first fitting part; a second fitting part is provided on the outer periphery of the lower part corresponding to the position of the first fitting part, the second fitting part is inserted through the opening and fitted together with the first fitting part; a groove is provided on the outer periphery of the lower part, and a sealing ring is provided inside the groove. A third connecting part, a first connecting part, and a second connecting part are respectively provided on the float cover, the float neck, and the lower part of the float. The connection between the first and third connecting parts allows for a tight connection between the float cover and the float neck. The connection between the first and second connecting parts allows for a tight connection between the upper and lower parts of the float when stacked. This invention, by providing a guide part and a first fitting part on the upper part of the float, and a second fitting part on the lower part of the float, allows for quick disassembly and assembly of the upper and lower parts of the float. By providing a sealing ring in the groove at the lower part of the float, the overall structure of the float is sealed, preventing water ingress during use.

[0007] As an optimization, in the aforementioned float for impeller-type aerators, the second fitting part includes a vertical part and a horizontal part.

[0008] As an optimization, in the aforementioned float for impeller-type aerators, the guide portion is an inclined surface structure that slopes towards the opening, and the guide portion exerts a pressure force on the vertical part of the second fitting portion.

[0011] As an optimization, in the aforementioned float for impeller-type aerators, the first connecting part is located on the inner side of the float neck along the neck opening and has a concave threaded structure; the second connecting part is located at the center of the bottom of the lower part of the float and has a raised threaded structure; the third connecting part is located on the inner side of the float cover and has a raised threaded structure.

[0012] As an optimization, in the aforementioned float for impeller-type aerators, an opening is provided on the outer side of the second fitting portion. This opening prevents water accumulation, thereby preventing water from seeping into the float.

[0013] As an optimization, in the aforementioned float for impeller-type aerators, the sealing ring is an O-ring.

[0014] As an optimization, in the aforementioned float for impeller-type aerators, the outer circumferential diameters of the upper and lower parts of the float are the same, and when the outer circumferential diameter is the axis of symmetry, it is an asymmetrical shell structure. This structural design allows the upper and lower parts of the float to be stacked, thereby improving space utilization and reducing transportation and storage costs during storage and transportation.

[0015] The technical solution of this utility model for an aerator is as follows:

[0016] An impeller aerator includes the aforementioned float for an impeller aerator.

[0018] As an optimization, in the aforementioned impeller-type aerator, a ball neck sleeve is provided at the end of the support rod, and the ball neck sleeve mates with the ball neck. The ball neck sleeve is used to cover the ball neck of the float, and then the float cover bolt is tightened on the ball neck to achieve a tight connection between the float and the support rod.

[0019] As an optimization, in the aforementioned impeller aerator, the number of floats is at least three. At least three floats ensure stable operation of the impeller aerator.

[0020] Compared with the prior art, the technical effects of this utility model are as follows: (1) By setting the float as a split structure of the upper part and the lower part of the float, and setting the upper part and the lower part of the float as an asymmetrical structure, the upper part and the lower part of the float can be stacked, which facilitates the storage and transportation of the float, improves the utilization rate of transportation and storage space, and reduces transportation and storage costs. (2) The outer periphery of the upper part of the float is provided with a guide part and a first fitting part, and the outer periphery of the lower part of the float is provided with a second fitting part at the position corresponding to the first fitting part.

Detailed Implementation

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings, but this should not be construed as limiting the present utility model. Contents not described in detail in the following embodiments are all common knowledge in the art or can be implemented using conventional technical means in the art.

[0030] Reference to embodiments of this utility model Figure 1-7 .

[0031] Traditional floats (3) are integral structures, which are space-consuming and inconvenient to transport and store. This invention designs the float (3) as a split structure, consisting of an upper part (5) and a lower part (6), which can be stacked and fixedly connected, facilitating placement during transport and storage. Designing the float (3) as a split structure requires solving two problems: firstly, the disassembly and assembly of the split structure must be simple and quick; secondly, the assembled split structure must have good sealing properties to prevent water ingress. To solve these two problems, this invention proposes a float for an impeller-type aerator.

[0032] like Figure 2 As shown, the float 3 includes a float cover 7, a float neck 4, an upper float part 5, and a lower float part 6. The float cover 7 is screwed onto the float neck 4, and the upper float part 5 is fitted onto the lower float part 6. The float 3 has a hollow shell structure.

[0033] like Figure 7 As shown, the float cover 7 includes a third connecting portion 71, which is a threaded structure with a protrusion inside the float cover 7. The ball neck 4 includes a first connecting portion 41, which is located on the inner side of the neck of the ball neck 4 at the neck opening position. The first connecting portion 41 is a concave threaded structure and can be threadedly connected to the third connecting portion 71. A second connecting portion 62 is provided at the bottom center position of the lower part 6 of the float, and the second connecting portion 62 is a protruding threaded structure. Figure 6 As shown, the second connecting part 62 can be threadedly connected to the first connecting part 41.

[0034] like Figure 2 As shown, the upper part 5 and the lower part 6 of the float are fitted together. Figure 3 As shown, at the junction of the lower part 6 and the upper part 5 of the float, multiple second fitting portions 61 are provided on the outer periphery of the lower part 6. Each second fitting portion 61 is a protruding "7"-shaped structure, including a vertical portion 611 and a horizontal portion 612. The transition point between the vertical portion 611 and the horizontal portion 612 is an arc-shaped structure. An opening 62 is provided on the outer side of the second fitting portion 61 to facilitate water drainage and prevent water accumulation.

[0035] like Figure 3 and4 As shown, at the junction of the upper part 5 and the lower part 6 of the float, a first fitting part 52 and a guide part 51 are provided at the position corresponding to the second fitting part 61 on the outer periphery of the upper part 5 of the float. An opening 53 is provided between the guide part 51 and the first fitting part 52, and the opening 53 is used for the insertion of the second fitting part 61. Figure 3 As shown, the guide portion 51 is disposed in a groove on the outer periphery of the upper part 5 of the float. The first fitting portion 52 is disposed on one side of the groove and is integral with the side of the groove. The first fitting portion 52 is an inclined surface structure inclined towards the guide portion 51. The guide portion 5 is an inclined surface structure that can be slightly deformed under external pressure. The second fitting portion 61 is inserted along the opening 53, and the guide portion 51 is pressed and guided by the guide portion 51 to continue insertion until the horizontal portion 612 of the second fitting portion 61 locks the first fitting portion 52. At this time, the guide portion 51 has a pressing force on the vertical portion 611 of the second fitting portion 61, thereby fitting and fixing the upper part 5 of the float and the lower part 6 of the float.

[0036] like Figure 3 As shown, a groove is provided along the outer periphery of the lower part 6 of the float, and a sealing ring 8, which is an O-ring, is provided inside the groove. At the sealing ring 8, the upper part 5 and the lower part 6 of the float are in close contact.

[0037] like Figure 5 , 6 As shown, in order to stack the upper part 5 and the lower part 6 of the float, when the outer diameters of the upper part 5 and the lower part 6 of the float are the same and the outer diameters are the axis of symmetry, the upper part 5 and the lower part 6 of the float have an asymmetrical structure. The float 3 is a hollow shell structure. Figure 5 As shown, stacking the upper part 5 and the lower part 6 of the float can improve the utilization rate of the transport and storage space and reduce the transport and storage costs of the float during the transportation and storage process.

[0038] This utility model provides an impeller aerator having the aforementioned float 3 structure for an impeller aerator, such as... Figure 1 As shown, the system includes an aerator main unit 1, which is connected to floats 3 via a support rod 2. There are at least three floats 3, symmetrically placed around the aerator main unit 1. In this embodiment, there are three floats 3. The neck 4 of each float 3 is inserted into the neck sleeve 21 of the support rod 2, and then the float cover 7 is bolted to the neck 4 to connect and fix the float 3 to the support rod 2.

[0039] The foregoing general description of the utility model and its specific embodiments should not be construed as limiting the technical solution of the utility model. Those skilled in the art, based on the disclosure of this application, can add, reduce, or combine the disclosed technical features in the foregoing general description and / or specific embodiments (including examples) without departing from the constituent elements of the utility model, to form other technical solutions within the protection scope of this utility model.
