Abstract
Description
A wave-shaped impeller structure Technical Field
[0001] This utility model relates to the field of wind turbine impeller technology, specifically a wave-shaped impeller structure. Background Technology
[0002] The impeller is the core component of a fan. It mainly converts the mechanical energy of the prime mover into the kinetic and pressure energy of the fluid (air or gas) through rotation. Its design and performance directly affect the fan's air volume, air pressure, efficiency, and operational stability. The wave-shaped impeller also has the effect of reducing noise and enhancing stability compared to a normal impeller.
[0003] Currently, due to the special shape of the wave-shaped impeller, dust and other impurities easily adhere to its surface in dusty working environments, which is very detrimental to the normal operation of the fan and requires regular cleaning. Since the impeller is connected to the motor through a coupling, frequent disassembly can easily cause wear on the bolts and threads, reducing the life of the coupling. Summary of the Invention
[0004] The purpose of this invention is to provide a wave-shaped impeller structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wave-shaped impeller structure, comprising: a main body; a rotating shaft, fixedly disposed inside the main body to drive the main body to rotate; a retainer, fixedly disposed on the main body, the rotating shaft passing through the inside of the retainer; a plurality of retaining strips, fixedly disposed inside the retainer, the surfaces of the retaining strips being in contact with the surface of the rotating shaft; a plurality of fixing grooves, formed on the surface of the rotating shaft; an adjusting sleeve, threaded onto the retainer; and a pressing bevel, clamped onto the inner surface of the adjusting sleeve; wherein the adjusting sleeve is configured such that when rotated, the pressing bevel presses against the retaining strips, causing one end of the retaining strip to enter the fixing groove.
[0006] Preferably, it further includes: a through hole, which is formed through the outer surface of the adjusting sleeve; a positioning bolt, which is fixedly disposed inside the through hole; and a plurality of slots, which are formed on the outer surface of the slot, and the slots are evenly distributed along the surface of the slot; when the positioning bolt is configured to extend one end into the slot, the position of the adjusting sleeve is fixed.
[0007] Preferably, it further includes: a rubber pad disposed on the adjusting sleeve, wherein the surface of the positioning bolt abuts against the surface of the rubber pad.
[0008] Preferably, it also includes: anti-slip texture, formed on the surface of the adjustment sleeve.
[0009] Preferably, it further includes: a positioning cover, disposed at one end of the rotating shaft, the one end of the positioning cover abutting against one end of the main body; and a fixing bolt, disposed on the positioning cover, the one end of the fixing bolt being fixedly disposed to one end of the rotating shaft.
[0010] Preferably, it further includes: a guide surface, formed on the end face of the card strip, wherein the extrusion bevel is in contact with the guide surface.
[0011] Preferably, a number of blades are fixedly mounted on the main body, and the blades are wavy in shape.
[0012] This utility model provides a wave-shaped impeller structure, which has the following beneficial effects:
[0013] (1) This utility model rotates the adjusting sleeve so that the adjusting sleeve moves on the card seat. During the movement of the adjusting sleeve, the squeezing inclined surface applies force to the card strip, causing the card strip to bend into the fixed groove, thereby achieving the fixation between the main body and the rotating shaft. The structure is simple and easy to operate, which improves the disassembly efficiency of the impeller and does not require disassembly of the coupling, thus improving the service life of the coupling.
[0014] (2) By setting up positioning bolts, through holes and slots, this utility model can limit the adjustment sleeve so that it cannot rotate, avoid the vibration generated during the rotation of the impeller causing the adjustment sleeve to loosen, and improve the fixing strength.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: Referring to 1-5, in this embodiment, a wave-shaped impeller structure includes: a main body 1; a rotating shaft 2, fixedly disposed inside the main body 1, driving the main body 1 to rotate; a retainer 3, fixedly disposed on the main body 1, with the rotating shaft 2 passing through the inside of the retainer 3; a plurality of retaining strips 4, fixedly disposed inside the retainer 3, with the surface of the retaining strips 4 in contact with the surface of the rotating shaft 2; a plurality of fixing grooves 15, formed on the surface of the rotating shaft 2; an adjusting sleeve 5, threaded onto the retainer 3; and a pressing inclined surface 6, clamped onto the inner surface of the adjusting sleeve 5. When the adjusting sleeve 5 is rotated, the pressing inclined surface 6 presses the retaining strips 4 so that one end of the retaining strips 4 enters the inside of the fixing groove 15. By setting the retaining strips 4, the main body 1 and the rotating shaft 2 can be connected together through cooperation with the fixing groove 15, so that when the rotating shaft 2 rotates, it can drive the main body 1 to rotate together. By setting the pressing inclined surface 6, a pushing force can be applied to the retaining strips 4, allowing them to enter the inside of the fixing groove 15. Furthermore, the strength of the retaining strips 4 can be improved through subsequent pressing and fitting.
[0023] It also includes: a through hole 7, which is opened through the outer surface of the adjusting sleeve 5; a positioning bolt 8, which is fixedly set inside the through hole 7; and several slots 9, which are opened on the outer surface of the seat 3 and are evenly distributed along the surface of the seat 3. When the positioning bolt 8 is set to extend into the slot 9 at one end, the position of the adjusting sleeve 5 is fixed. Through the cooperation between the slot 9 and the positioning bolt 8, the position of the adjusting sleeve 5 can be fixed to prevent it from becoming loose.
[0024] It also includes: a rubber pad 10, which is set on the adjusting sleeve 5, and the surface of the positioning bolt 8 abuts against the surface of the rubber pad 10 to improve the connection strength between the positioning bolt 8 and the through hole 7 and prevent it from loosening.
[0025] It also includes: anti-slip texture 11, which is formed on the surface of the adjustment sleeve 5 to facilitate the user to adjust the adjustment sleeve 5.
[0026] It also includes: a positioning cover 12, which is set at one end of the rotating shaft 2, with one end of the positioning cover 12 abutting against one end of the main body 1; and a fixing bolt 13, which is set on the positioning cover 12, with one end of the fixing bolt 13 fixedly set to one end of the rotating shaft 2, to further improve the connection strength and prevent it from falling off.
[0027] It also includes: a guide surface 16, which is opened on the end face of the card strip 4, and the extrusion slope 6 is in contact with the guide surface 16 to guide the deformation direction.
[0028] Several blades 14 are fixedly mounted on the main body 1. The blades 14 are wavy in shape and have excellent noise reduction effect.
[0029] This utility model provides a wave-shaped impeller structure, the specific working principle of which is as follows:
[0030] When cleaning and disassembling the impeller, the staff first uses a tool to rotate the positioning bolt 8 so that one end of it is disengaged from the slot 9, thus releasing the restriction on the adjusting sleeve 5. Then, the adjusting sleeve 5 is rotated to separate the pressing inclined surface 6 from the retaining strip 4. After separation, the staff can remove the fixing bolt 13 to directly remove the impeller for cleaning.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
