[0028] like Figures 1 to 5As shown, a lubricating device for a power station dynamically adjustable axial flow fan comprises: a fixed tube 1, a motor 102 is provided on the outside of the fixed tube 1, a fixed frame 104 and a fan blade are provided inside the fixed tube 1, and a synchronous belt 103 is provided at the output end of the motor 102; a connecting component 4 is provided inside the fixed frame 104 for providing power transmission to the fan blade, the connecting component 4 comprises a lubricating part and a transmission part, the lubricating part is provided inside the fixed frame 104, the transmission part is provided inside the lubricating part, and the lubricating part cooperates with the transmission part to guide the oil; a circulating component 2 is provided inside the fixed tube 1 for circulating the oil To cool down, specifically, during the use of the fan, lubricating oil is added to the inside of the connecting component 4 through the circulation component 2. The added oil fully lubricates the fan during use under the guidance of the connecting component 4 to avoid wear of the fan due to long-term use. The fan blades are arranged inside the fixed tube 1, so that during use, the fan blades are driven to rotate by the cooperation of the motor 102 and the synchronous belt 103 to achieve the effect of driving air flow. The fixed frame 104 provides support for the fan blades to avoid the fan blades from moving relative to the fixed tube 1 during use.

[0029] like Figures 1 to 5 As shown, a mounting bracket 101 and a storage component 3 are further provided on the outside of the fixed tube 1. Specifically, the position of the fixed tube 1 is fixed by the mounting bracket 101, and the storage component 3 and the fixed tube 1 can be connected by welding or threading. A filling port is provided on the outside of the storage component 3 to facilitate the filling of lubricating oil during use. The storage component 3 is a sealed container that can store lubricating oil. There is no restriction on the shape of the storage component 3 during use, such as cylindrical or cubic box shape.

[0030] like Figures 1 to 5 As shown, the lubricating part includes a fixed sleeve 403, which is arranged inside the fixed frame 104, and the axis of the fixed sleeve 403 is parallel to the opening direction of the fixed tube 1, and a first lubrication groove 405 is provided inside the fixed sleeve 403. Liquid storage tanks 404 are provided at both ends of the first lubrication groove 405. Specifically, the liquid storage tanks 404 inside the fixed sleeve 403 can temporarily store lubricating oil, and the first lubrication groove 405 is connected to the liquid storage tanks 404 at both ends, so that the lubricating oil can flow inside the liquid storage tank 404 and the first lubrication groove 405 during use, providing lubrication to the transmission part during the flow of the lubricating oil. The first lubrication groove 405 can be in the shape of a spiral groove or an inclined groove. The first lubrication groove 405 can guide the flow direction of the lubricating oil during use, so that the lubricating oil can flow evenly inside the fixed sleeve 403, avoiding the existence of lubrication dead corners during the lubrication process.

[0031] like Figures 1 to 5As shown, the transmission member includes a rotating shaft 401, which is arranged inside a fixed sleeve 403. The rotating shaft 401 rotates relative to the fixed sleeve 403, and the axis of the rotating shaft 401 coincides with the axis of the fixed sleeve 403. A plurality of spiral pieces 402 are provided on the outside of the rotating shaft 401. The spiral pieces 402 correspond to the liquid storage tank 404, and the spiral pieces 402 rotate inside the liquid storage tank 404. One end of the rotating shaft 401 is connected to the fan blade, and the other end of the rotating shaft 401 is connected to the synchronous belt 103. Specifically, The other end of the rotating shaft 401 and the output end of the motor 102 are both provided with pulleys, and the synchronous belt 103 is arranged on the outside of the pulley, so that when in use, the power is transmitted to the fan blades through the cooperation of the synchronous belt 103 and the rotating shaft 401, and the spiral pieces 402 rotate in a spiral manner. The spiral directions of the spiral pieces 402 are the same, ensuring that the flow direction of the lubricating oil is the same. During the rotation of the rotating shaft 401, the spiral pieces 402 can be driven to rotate inside the liquid storage tank 404. The spiral spiral pieces 402 can rotate in the process of rotation. The first lubricating groove 405 can push the lubricating oil from the liquid reservoir 404 at one end to the inside of the liquid reservoir 404 at the other end, thereby achieving the effect of the lubricating oil flowing inside the fixed sleeve 403. Both ends of the fixed sleeve 403 are provided with sealing rings to block the lubricating oil, thereby preventing the lubricating oil from leaking from both ends of the fixed sleeve 403 during the lubrication process. During the use of the fan, the motor 102 and the synchronous belt 103 are first used to drive the rotating shaft 401 and the fan blades to rotate. When the rotating shaft 401 rotates, the spiral piece 402 is also driven to rotate. Since the spiral piece 402 rotates inside the liquid reservoir 404, it can promote the lubricating oil temporarily stored in the liquid reservoir 404 to circulate. During the circulation of the lubricating oil, the temperature between the rotating shaft 401 and the fixed sleeve 403 can be absorbed. At the same time, the circulation component 2 is used to cool the lubricating oil after absorbing heat, thereby preventing the temperature between the rotating shaft 401 and the fixed sleeve 403 from being too high, thereby preventing the contact surface between the rotating shaft 401 and the fixed sleeve 403 from being damaged.

[0032] like Figures 1 to 5 As shown, a second lubrication groove 406 is further provided on the outside of the rotating shaft 401, and the second lubrication groove 406 is arranged between the spiral sheets 402. Specifically, the second lubrication groove 406 on the outside of the rotating shaft 401 can further guide the lubricating oil flowing inside the fixed sleeve 403, ensuring that the lubricating oil can fully flow between the rotating shaft 401 and the fixed sleeve 403.

[0033] like Figures 1 to 5As shown, the circulation component 2 includes a guide pipe 201 and a connecting pipe 204. The guide pipe 201 is arranged inside the fixed pipe 1. The two ends of the guide pipe 201 are respectively provided with a liquid inlet pipe 202 and a liquid outlet pipe 203. The connecting pipe 204 and the liquid outlet pipe 203 are connected to the storage member 3. The connecting pipe 204 and the liquid inlet pipe 202 are both connected to the fixed sleeve 403, and the connecting pipe 204 and the liquid inlet pipe 202 are connected to the liquid storage tank 404. Specifically, the shape of the guide pipe 201 can be a spiral coil or a serpentine tube, so as to increase the contact area with the air during use, so that the lubricating oil liquid after absorbing heat can be cooled during use. The guide tube 201 is made of a material with good heat transfer. The air flowing during the rotation of the fan blades further increases the heat dissipation effect of the guide tube 201. The cooperation of the connecting tube 204, the liquid inlet pipe 202, the guide tube 201 and the liquid outlet pipe 203 can recycle the lubricating oil stored in the storage component 3. When in use, the connecting tube 204 introduces the lubricating oil stored in the storage component 3 into the liquid storage tank 404. The introduced lubricating oil flows into the guide tube 201 through the liquid inlet pipe 202 under the push of the spiral sheet 402 for cooling. The cooled lubricating oil flows into the storage component 3 through the liquid outlet pipe 203 for recycling.
