Description

Technical Field

[0001] The present invention belongs to the technical field of aeration equipment, and particularly relates to a waterproof and heat dissipation structure and an aerator using the structure. Background Art

[0002] China is a major country in aquaculture in the world. The pond aquaculture area alone reaches about 20 million mu, and the aquaculture output ranks first in the world. Recently, with the continuous expansion of the aquaculture area and density in China and the increasingly harsh weather conditions, the requirement of aquatic products for dissolved oxygen is getting higher and higher. Low dissolved oxygen makes them breathe faster, and lower dissolved oxygen will cause them to float on the water surface or even die.

[0003] Generally, the lack of oxygen in fish ponds often occurs at night, especially at dawn when the air pressure is low and the dissolved oxygen is the lowest. Aquaculture farmers stay up all night to observe the fish population. The main purpose of the aerator is to increase the dissolved oxygen in the water body. It can comprehensively utilize physical, chemical, and biological functions. It can not only solve the problem of fish floating on the water surface due to lack of oxygen in pond aquaculture, but also eliminate harmful gases, promote the convective exchange of water bodies, improve water quality conditions, increase the activity and primary productivity of fish ponds, thereby increasing the stocking density, enhancing the feeding intensity of aquaculture objects, promoting growth, and significantly increasing the per mu yield, fully achieving the purpose of increasing aquaculture income.

[0004] Since the aerator is used in places with water such as fish ponds, the water splashes generated during use often spray onto the aerator from all directions. There is a motor structure inside the aerator, and once water enters, it will cause certain damage to the internal structure of the aerator and shorten the service life of the aerator.

[0005] Currently, most aerators on the market are waterproof by setting a waterproof cover on the motor housing. The motor is protected by the waterproof cover to achieve the waterproof effect. This waterproof method has a complex structure, a large volume, and will cause heat dissipation problems for the motor. At the same time, it cannot solve the problem of condensed water inside the waterproof cover.

[0006] Therefore, it is necessary to design a new waterproof and heat dissipation structure for the aerator. Summary of the Invention

[0007] The purpose of the present invention is to solve the problems that the waterproof structure of the existing aerator is complex and cannot solve the heat dissipation and condensed water problems, and to provide a waterproof and heat dissipation structure and an aerator using the structure.

[0008] To achieve the above object, the technical solution adopted by the present invention is: a waterproof and heat dissipation structure, including an installation body, one end of the installation body is configured as a connection end, and the other end is configured as a receiving end. The connection end includes a first connection sleeve and a second connection sleeve arranged coaxially. A shaft hole penetrating the installation body is provided at the center of the first connection sleeve. A plurality of through holes communicating with the inside of the receiving end are provided between the first connection sleeve and the second connection sleeve. A plurality of heat dissipation fins are provided on the outer side wall of the receiving end.

[0009] Preferably, the first connection sleeve is arranged inside the second connection sleeve, and the height of the second connection sleeve is greater than that of the first connection sleeve.

[0010] Preferably, a plurality of support ribs are provided between the first connection sleeve and the second connection sleeve. The height of the support ribs is the same as that of the first connection sleeve, and the through holes are arranged between adjacent support ribs.

[0011] Preferably, a concave end cover is provided at the end of the receiving end away from the connection end, and the end cover is made of nylon material.

[0012] Preferably, a drive board is accommodated in the receiving end. A junction box for connecting the drive board is provided on the side wall of the receiving end, and air vents are provided in the junction box.

[0013] Preferably, three connection seats are evenly distributed in the circumferential direction on the outer side wall of the receiving end, and threaded holes are provided at the bottoms of the connection seats.

[0014] An aerator includes the above waterproof and heat dissipation structure, including a direct drive motor. The motor shaft of the direct drive motor is installed in a shaft hole matching it. A first waterproof platform and a second waterproof platform are provided on the motor shaft. The first connection sleeve is sleeved outside the first waterproof platform, and the second connection sleeve is sleeved outside the second waterproof platform; it includes a floating ball, and the floating ball is fixedly connected to the connection seat through a bracket.

[0015] Preferably, the first connection sleeve is tightly sleeved outside the first waterproof platform, and the ends of the first connection sleeve and the support ribs abut against the end face of the second waterproof platform.

[0016] Preferably, a gap communicating with the through holes is left between the second connection sleeve and the second waterproof platform.

[0017] After adopting the above technical solution, a waterproof and heat dissipation structure provided by the present invention and an aerator using this structure have the following beneficial effects:

[0018] 1) Through the integrated design of the connection end and the receiving end, the present invention realizes the integrated design of the waterproof structure and the heat dissipation structure, solves the disadvantages of the separate design of the waterproof structure and the heat dissipation structure in the prior art, and solves the problems of complex structure, unclear effect, and high cost;

[0019] 2) The present invention respectively sleevs the first connecting sleeve and the second connecting sleeve on the outer sides of the first waterproof platform and the second waterproof platform of the direct drive motor. Through the stepped design of the first waterproof platform and the second waterproof platform, and the buckling connection mode between the connecting end and the motor shaft end, the structure is simple and has a good waterproof effect at the same time;

[0020] 3) Through the design of the heat dissipation fins on the outer side wall of the accommodating end, the present invention can enable the installation body to have a good heat dissipation effect. At the same time, the design of the concave end cover can enable the condensed water generated inside the end cover due to the day-night temperature difference to flow down along the inner wall of the accommodating end from the periphery of the end cover, without affecting the driving board inside the accommodating end. At the same time, the condensed water can flow out between the second connecting sleeve and the second waterproof platform along the through hole; The concave end cover is made of nylon material, which has advantages such as large thermal resistance and good heat insulation effect;

[0021] 4) Through the design of the connecting seat on the outer side wall of the accommodating end, the present invention can enable the float mounting bracket to be fixedly connected with just one screw, which has the advantages of convenient disassembly and low cost.

DETAILED DESCRIPTION OF THE INVENTION

[0028] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0029] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "attachment", "fixation" and the like shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] As Figures 1-5 shown, a waterproof and heat-dissipating structure provided by the present invention includes an installation body 1. One end of the installation body 1 is configured as a connection end 2, and the other end is configured as a receiving end 3, that is, the connection end 2 and the receiving end 3 are integrally formed. The connection end 2 includes a first connection sleeve 4 and a second connection sleeve 5 arranged coaxially. A shaft hole 6 penetrating the installation body 1 is provided at the center of the first connection sleeve 4. The shaft hole 6 is an oval shaft hole. Specifically, the first connection sleeve 4 is arranged inside the second connection sleeve 5, and the height of the second connection sleeve 5 is greater than that of the first connection sleeve 4. A plurality of through holes 7 communicating with the inside of the receiving end 3 are provided between the first connection sleeve 4 and the second connection sleeve 5. Specifically, a plurality of support ribs 9 are provided between the first connection sleeve 4 and the second connection sleeve 5. The height of the support ribs 9 is the same as that of the first connection sleeve 4. The through holes 7 are provided between adjacent support ribs 9.

[0031] Furthermore, a driving board 11 is accommodated in the receiving end 3. A junction box 12 for connecting the driving board 11 is provided on the side wall of the receiving end 3. An air vent hole 13 is provided in the junction box 12 to enhance the air permeability inside the receiving end 3, that is, the connection between the outer cover of the junction box 12 and the junction box 12 is not completely sealed and a gap can be left to ensure air permeability, that is, to further enhance the heat dissipation effect and reduce the generation of condensed water. An inwardly concave end cap 10 is provided at the end of the receiving end 3 away from the connection end 2. The inwardly concave design of the end cap 10 enables condensed water to flow down along the lower periphery when condensed water is formed inside the end cap 10, without damaging the driving board 11. The end cap 10 is made of nylon material, which has advantages such as high thermal resistance and good heat insulation effect.

[0032] Furthermore, a plurality of heat dissipation fins 8 are provided on the outer side wall of the receiving end 3, which can provide a good heat dissipation effect for the installation body 1. Three connection seats 14 are evenly distributed in the circumferential direction on the outer side wall of the receiving end 3. A threaded hole 15 is provided at the bottom of the connection seat 14.

[0033] The present invention also provides an aerator, which includes the above waterproof and heat dissipation structure, a direct drive motor 16 and a floating ball. The motor shaft 17 of the direct drive motor 16 is installed in a shaft hole 6 that matches it. A first waterproof platform 18 and a second waterproof platform 19 that match the first connecting sleeve 4 and the second connecting sleeve 5 are provided on the motor shaft 17, that is, the first waterproof platform 18 is arranged on the second waterproof platform 19. The first connecting sleeve 4 is sleeved outside the first waterproof platform 18, and the second connecting sleeve 5 is sleeved outside the second waterproof platform 19. With such a design, through the double protection of the first connecting sleeve 4 and the second connecting sleeve 5 from outside to inside and from bottom to top, it can effectively prevent water splashes from entering the motor shaft when the aerator is in use, thus avoiding the phenomenon of damage to the aerator.

[0034] Further, the first connecting sleeve 4 is tightly sleeved outside the first waterproof platform 18, and the end of the first connecting sleeve 4 and the support rib 9 abuts against the end face of the second waterproof platform 19, which can not only ensure the waterproof performance of the cooperation between the first connecting sleeve 4 and the first waterproof platform 18, but also ensure the stability of the connection between the waterproof and heat dissipation structure and the direct drive motor. A gap communicating with the through hole 7 is left between the second connecting sleeve 5 and the second waterproof platform 19. When there is condensed water inside the accommodating end 3, it can flow out from the through hole 7 and flow out of the outside of the installation body 1 along the gap between the second connecting sleeve 5 and the second waterproof platform 19.

[0035] Further, the floating ball is fixedly connected to the connecting seat 14 through a bracket. Specifically, one end of the bracket away from the floating ball is inserted into the connecting seat 14 and tightened by a screw in the threaded hole 15, so as to fix the bracket in the connecting seat 14. One screw can fix one bracket, which has the advantages of simple structure and convenient disassembly.

[0036] When the aerator is in use, the waterproof and heat dissipation structure is connected to the direct drive motor 16, and the outer rotor of the direct drive motor 16 is driven by the drive plate 11 to drive the outer blades to rotate, so as to achieve the effect of oxygenation. The waterproof and heat dissipation structure floats on the water surface under the action of the floating ball. When the aerator is working, the splashes generated can be first blocked outside by the second connecting sleeve 5 and the second waterproof platform 19 and will not enter the inside of the motor shaft. Even in special cases, if a little splash enters the inside of the second connecting sleeve 5 and the second waterproof platform 19, it will be blocked again by the first connecting sleeve 4 and the first waterproof platform 18 and flow down again between the second connecting sleeve 5 and the second waterproof platform 19 under the action of gravity. To sum up, through the above double waterproof protection, the splashes cannot enter the motor shaft part; in addition, during the use of the aerator, when condensate is generated in the end cover 10 due to the temperature difference between day and night, the condensate can flow along the arc of the end cover 10 to the periphery, flow down along the inner wall of the receiving end 3, and be discharged from the through hole 7. Similarly, under the action of the first connecting sleeve 4 and the first waterproof platform 18, the condensate cannot enter the motor shaft part either and can only flow out between the second connecting sleeve 5 and the second waterproof platform 19; in addition, through the arrangement of the heat dissipation fins 8 and the ventilation holes 13, the good heat dissipation performance during the use of the aerator can be ensured, the generation of condensate can be reduced, and the service life of the aerator can be further guaranteed.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
