Description

Technical Field

[0001] This application relates to the field of axial fans, and more particularly to an intelligent axial fan. Background Art

[0002] Axial fans are widely used. The air flow is in the same direction as the axis of the fan blades. For example, electric fans and the fans of air conditioner outdoor units operate in an axial flow manner. The reason for being called "axial flow" is that the gas flows parallel to the axis of the fan. Axial fans are usually used in occasions where a higher flow rate and a lower pressure are required. However, the existing axial fans are not convenient for angle adjustment, and manual adjustment has a low degree of automation and is time-consuming and laborious. Therefore, there is an urgent need for an intelligent axial fan to solve the above problems. Summary of the Invention

One end of the connecting block 318 abuts against the limiting member 317, one end is connected to the connecting block 318, and the other end is connected to the inner wall of the second accommodating cavity 322; wherein, an annular limiting groove 324 is provided at a position corresponding to the groove body 323 on the connecting seat 310.

When the cover plate 320 is installed on the fixed seat 316, the pressing block 321 presses the connecting block 318, the connecting block 318 moves downward, one end of the limiting member 317 disengages from the groove body 323, and the end of the limiting member 317 facing the connecting seat 310 moves, so that the other end of the limiting member 317 is inserted into the annular limiting groove 324 to limit the connecting seat 310, thereby ensuring that the connecting seat 310 can rotate stably, and further improving the stability of the angle adjustment of the blade 305.

[0066] The limiting member 317 includes a top rod 326, a connecting ring 327, and a second spring 328; the top rod 326 movably penetrates through the groove body 323. The connecting ring 327 is fixedly provided on the outer wall of the top rod 326.

The mounting base 301 is provided with a first heat dissipation vent 335 at one end of the fan 334, and the protective housing 333 is provided with a second heat dissipation vent 336 facing the output direction of the fan 334. The first and second heat dissipation vents 335 and 336 allow the fan 334 to exhaust air outward, continuously transferring heat generated by the shaft 302. This significantly enhances the cooling effect on the shaft 302 and prevents malfunctions caused by excessive shaft temperature. The heat conduction frame 337 is fixed to the inner wall of the mounting base 301 and is sleeved around the outer periphery of the shaft 302, contacting the shaft 302.

[0069] A bottom plate 338 is provided on the bottom of the mounting base 301. A third accommodation cavity 339 is provided in the placement rack 300.

A plurality of through cavities 348 are opened on the baffle 347, and the through cavities 348 are communicated with the oil storage chamber 346. When shock-absorbing, the first elastic member is compressed, the piston rod 342 slides in the cylinder 344, the cylinder 344 is filled with mechanical oil, the oil storage chamber 346 is filled with part of the mechanical oil, and the end of the oil storage chamber 346 away from the baffle 347 is filled with nitrogen. The gas can be compressed. When the piston assembly 345 presses down, the gas is compressed, and the mechanical oil flows from the through cavity 348 into the oil storage chamber 346. When the piston assembly 345 moves upward, the mechanical oil flows back from the through cavity 348 into the cylinder 344. The mechanical oil slows down the flow rate through the through cavity 348, and further slows down the sliding speed of the piston rod 342, reducing the number of rebounds of the first elastic member, thereby playing a role in reducing vibration.

[0072] The blade 305 is made of aluminum alloy, which can enhance the ability to bear the aerodynamic load of the wind blade 305 while reducing density, weight and cost, thereby reducing the fatigue load of the blade 305 and improving the fatigue life. Or in other embodiments, the blade 305 is treated with polyurethane coating for anti-corrosion. The waterborne polyurethane anti-corrosion coating forms a dense coating on the surface of the object to be coated. This coating can effectively isolate the matrix and the corrosive environment, prevent water, oxygen and other substances that may cause corrosion from contacting the protected surface. The polyurethane material itself has good chemical resistance and can resist the erosion of various chemical substances, which makes it perform well in the chemical corrosion environment. At the same time, the polyurethane material also has good anti-strain performance, and can maintain the continuity and protection ability of the coating even when the object deforms.
