Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to an ocean fan which is resistant to bearing corrosion. Background Art

[0002] Compared with hydropower, wind power, nuclear power, etc., solar power generation has no emissions and noise, mature application technology, and is safe and reliable. Therefore, developed countries have made long-term plans for the development and utilization of solar energy as the main content of the energy revolution. The best way to utilize solar energy is photovoltaic conversion, which is to use the photovoltaic effect to make sunlight shine on silicon materials to generate current and directly generate electricity.

[0003] With the rapid development of my country's photovoltaic industry, more and more offshore photovoltaic projects have emerged in recent years. Offshore photovoltaic projects can effectively utilize vast marine resources and reduce the occupation of land resources by constructing solar photovoltaic power generation systems in marine environments such as offshore and mudflats. As one of the main auxiliary components for heat dissipation in photovoltaic power generation systems, the reliability and service life of the fan affect the operation of the photovoltaic power generation system. When the fan is operating at sea, if its interior is invaded by seawater, salt spray, dust, etc., after a long time, the fan bearing will be corroded by seawater and dust, affecting the reliability of the fan operation and reducing the service life of the fan. Therefore, the anti-corrosion of fan bearings is a problem that technicians in this field continue to work on. Utility Model Content

[0031] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0032] Combination Figures 1 to 3 As shown, the anti-bearing corrosion marine fan of this embodiment mainly includes: an outer frame 1, a support sleeve 2, a winding motor 3, a shaft core 4, a blade assembly 5 and a sealing assembly. Among them, a mounting hole is provided on the bottom wall 11 of the outer frame 1, and the support sleeve 2 is fixedly installed on the bottom wall 11 through the mounting hole. The support sleeve 2 can be a copper sleeve; the winding motor 3 is sleeved on the outer wall of the support sleeve 2; the shaft core 4 is rotatably connected to the inner wall of the support sleeve 2 through a bearing; the blade assembly 5 is fixedly connected to the shaft core 4 and can rotate with the shaft core 4; the sealing assembly includes a first sealing member arranged at one end of the support sleeve 2 and a second sealing member 72 arranged at the other end of the support sleeve 2, and the first sealing member is sleeved on the shaft core 4.

[0033] Specifically, if Figure 2 As shown, the shaft core 4 of this embodiment is connected to the inner wall of the support sleeve 2 through the first bearing 61 and the second bearing 62 to improve the rotation stability of the shaft core 4. The first seal is located at one end of the first bearing 61 away from the second bearing 62, and the second seal 72 is located at one end of the second bearing 62 away from the first bearing 61.

[0034] like Figure 3 As shown, the first seal includes a copper column 711, a permanent magnet ring 712 and a steel sleeve 713. The copper column 711 is sleeved on the shaft core 4, the permanent magnet ring 712 and the steel sleeve 713 are sleeved on the outer wall of the copper column 711 respectively, the permanent magnet ring 712 is located at one end of the steel sleeve 713 close to the first bearing 61, and a plurality of first grooves (not shown in the figure) are provided on the inner wall of the steel sleeve 713, and the first grooves are filled with magnetic fluid. The permanent magnet ring 712 can be a magnet ring. With the above scheme, the permanent magnet ring 712 and the magnetic fluid work together to form a good sealing structure, which plays a good protective role on the first bearing 61 and the second bearing 62, and prevents seawater and dust from flowing into the support sleeve 2 from the end where the first seal is located and corroding the two bearings.

[0035] The second sealing member 72 can be a rubber magnet. The rubber magnet can play a sealing role on one hand, preventing seawater and dust from entering the support sleeve 2 from the end where it is located and corroding the bearing; on the other hand, it can generate magnetic attraction to the shaft core 4, so that the two bearings are evenly stressed.

The third body 53 has an inner cavity 531 at one end facing the support sleeve 2, and the inner cavity 531 is used for the end of the support sleeve 2 to extend into. With the above scheme, a structure similar to a maze can be formed between the end of the third body 53 and the end of the support sleeve 2, which can further prevent seawater and dust from entering the interior of the support sleeve 2. Preferably, there is a gap between the end of the support sleeve 2 and the bottom of the inner cavity 531. In other words, the end of the support sleeve 2 does not contact the bottom of the inner cavity 531, so as not to affect the rotation of the fan blade assembly 5.

[0037] Preferably, in order to prevent the fan blades 54 from being stuck by salt due to salt mist crystallization, Figure 2 and Figure 4As shown, the first body 51 of this embodiment is connected to the fourth body 55 at one end facing the bottom wall 11 of the outer frame 1, and the bottom wall 11 of the outer frame 1 is provided with a second groove so that the end of the fourth body 55 extends therein, and the outer wall of the fourth body 55 is provided with a plurality of guide wings 56.

[0038] like Figure 2 As shown, the winding motor 3 of this embodiment has an injection-molded insulating seat 31 outside its core. In other words, the core of the winding motor 3 is insulated by injection molding, which is beneficial to prevent seawater from corroding the core of the winding motor 3.

[0039] In summary, the fan of this embodiment has the following advantages:

[0040] 1. The permanent magnet ring 712 of the first seal and the magnetic fluid work together to form a good sealing structure, which provides good protection for the first bearing 61 and the second bearing 62, and prevents seawater and dust from flowing into the support sleeve 2 from one end of the first seal and corroding the two bearings.

[0041] 2. The rubber magnet of the second sealing member 72 can play a sealing role on the one hand to prevent seawater and dust from entering the support sleeve 2 from the end where it is located and corroding the bearing; on the other hand, it can generate magnetic attraction to the shaft core 4 so that the two bearings are evenly stressed.

[0042] 3. A maze-like structure can be formed between the end of the third main body 53 of the fan blade assembly 5 and the end of the support sleeve 2, which can further prevent seawater and dust from entering the interior of the support sleeve 2.

[0043] 4. The guide wings 56 can sweep away salt crystals during rotation to prevent the fan blades 54 from being stuck by salt.

[0044] 5. The iron core of the winding motor 3 is insulated by the injection molding process, which is beneficial to prevent seawater from corroding the iron core of the winding motor 3.
