Description

Technical Field

[0001] The invention belongs to the field of impellers, and in particular relates to a noise-reducing impeller with a heat dissipation function. Background Art

[0002] With the development of industrial technology, modern impeller technology has become more and more perfect. For the impellers used in locomotive air conditioners, there will be a certain noise during the high-speed rotation of the locomotive impeller, which will affect the driver. In addition, different models require a variety of impellers. The shape of the impeller in the past was one-piece and could not be changed, which requires the customization of different impellers. After the impeller has been used for a period of time, dust will accumulate at the corners of the blades. It is rather troublesome to take out the impeller and wipe off the dust. If it is in the wild and it is difficult to find a suitable tool, if the staff's fingers cannot be inserted into the gap of the impeller for cleaning, it is necessary to use a stick wrapped with a cloth strip to wipe it, which is a rather troublesome operation. Summary of the Invention

[0003] The object of the present invention is to address the deficiencies of the prior art and provide a noise-reducing impeller with a heat dissipation function. When the device is in use, the impeller hub and blades rotate at high speed, and the air inside the blades flows from the inside of the blades to the outside of the blades under the action of centrifugal force. When negative pressure is formed inside the blades, air is replenished from the air duct, and then the impeller hub and blades can continuously agitate the airflow from the inside to the outside. When the gap between the blades needs to be adjusted, the stabilizing ring is removed, and the staff rotates the angle of the jumper ring again. The torsional groove on the top of the jumper ring drives the sliding bar at the bottom of the blade, and all the blades rotate to a certain angle. The locking bars on the top of all the blades are closed toward the axis of the impeller hub. When the stabilizing ring is assembled again, the locking bar on the top of the blade can be connected to the locking sleeve on the inner side, and then the blades can be positioned at three angles, and the gap between the blades can also be changed to three widths, thereby solving the problems mentioned in the background technology.

[0004] To solve the above problems, the present invention provides the following technical solutions: a noise reduction impeller with heat dissipation function, comprising an impeller hub, a plurality of blades in an annular array are arranged on the top of the impeller hub, the edges of the blades and the impeller hub are movably arranged, and an angle adjustment mechanism is provided at the bottom of the blades; a circular protrusion is provided in the middle of the impeller hub, and the circular protrusion in the middle of the impeller hub is stamped by a mold, an axial hole is provided at the center position of the impeller hub, a pipe shaft is inserted into the inside of the axial hole, and a plurality of air ducts are also provided on the outside of the axial hole; a dust removal component is also provided inside the pipe shaft.

[0005] During use, the impeller hub and blades rotate at high speed, and the air inside the blades flows from the inside to the outside of the blades under the action of centrifugal force. When negative pressure is formed inside the blades, air is replenished from the airway, and the impeller hub and blades can continuously stimulate the airflow from the inside to the outside.

[0010] Furthermore, the stabilizing mechanism includes a locking sleeve in an annular array at the bottom of the stabilizing ring, each group of locking sleeves consists of three, and a locking bar is provided at the top of the blade, the axis of the locking bar coincides with the axis of the sliding bar, and each group of locking sleeves can be plugged into the locking bar in the vertical direction, and the material of the locking sleeves is rubber.

When the stabilizing ring is assembled again, the locking strips on the top of the blades can be connected to the locking sleeves in the inner circle, so that the blades can be positioned at three angles and the gaps between the blades can also be changed to three widths.

[0012] Furthermore, the jumper ring is composed of two half rings, and the two half jumper rings are fixedly connected by countersunk bolts. A snap-fit piece is provided on the inner side wall of the jumper ring, and an annular groove matching the snap-fit piece is provided on the outer side wall of the impeller hub.

[0013] When in use, the cross-over ring is snapped together in two halves, which provides greater stability between the cross-over ring and the impeller hub.

[0015] During use, when the dust on the blades needs to be cleaned, the staff will remove the impeller assembly and push the lifting block upwards along the wire groove. When the root of the dust removal sheet is separated from the top end of the tube shaft, the two dust removal sheets can be laid flat and unfolded, and the dust removal sheets can be inserted into the gaps between the blades. Push the lifting block up and down along the wire groove, and the two dust removal sheets will be inserted up and down in the gaps between the blades to clean the dust.

The inside of the dust removal piece is a plastic plate, and the outside of the dust removal piece is wrapped with a sponge layer.

[0019] During use, the right-angled triangular spring piece is separated from the opening at the top of the tube shaft.

When negative pressure is formed inside the blades, air is replenished from the air duct, and then the impeller hub and blades can continuously agitate the airflow from the inside to the outside. When the gap between the blades needs to be adjusted, the stabilizing ring is removed, and the staff rotates the angle of the jumper ring again. The torsional groove on the top of the jumper ring will drive the sliding strip at the bottom of the blade, and all the blades will rotate to a certain angle. The locking strips on the top of all the blades are closed toward the axis of the impeller hub. When the stabilizing ring is assembled again, the locking strip on the top of the blade can be connected to the locking sleeve on the inner side, so that the blades can be positioned at three angles, and the gap between the blades can also be changed to three widths.

[0021] Secondly, when the dust on the blades needs to be cleaned, the staff will remove the impeller assembly and push the lifting block up along the wire groove. The right-angled triangular spring piece will detach from the opening at the top of the tube shaft. At this time, the right-angled triangular spring piece will be completely pushed out by the spring, and the two dust-removing pieces will also lie flat and unfold and be inserted into the gap between the blades. After the two dust-removing pieces are unfolded, the magnet blocks on their side walls will absorb the iron right-angled triangular spring piece, and push the lifting block up and down along the wire groove. The two dust-removing pieces will penetrate up and down in the gap between the blades to clean the dust. After pulling out the pin, the fixed short tube and the dust-removing piece can be converted to different angles to clean the dust. BRIEF DESCRIPTION OF THE DRAWINGS
