Description

Replaceable metal impeller

Technical Field

The utility model relates to the technical field of metal impellers, in particular to a replaceable metal impeller.

Background

The impeller is a wheel disc provided with movable blades, and can also be a wheel disc and a total of the movable blades arranged on the wheel discThe impellers can be classified according to the shape and the opening and closing conditions, and the impellers consist ofWheel hubThe wind passes through the impeller to drive the impeller to rotate, so that the generator is driven to rotate, wind energy is converted into electric energy, and at the moment, the impeller is required to have a large enough windward surface when rotating so as to extract enough energy from the wind; meanwhile, when the wind speed is too high, the windward angle of the blades needs to be automatically adjusted, the damage to machinery due to too high stress is avoided, the abrasion is accelerated due to the non-uniformity of gas flow inside the impeller, the damage to the center of the impeller is the largest, and unnecessary economic loss can be caused due to the fact that partial damage needs to be completely replaced, so that the replaceable metal impeller is provided.

SUMMERY OF THE UTILITY MODEL

The object of the present invention is to provide an alternative metal impeller to solve the problems set forth in the background above.

In order to achieve the purpose, the utility model provides the following technical scheme: the replaceable metal impeller comprises an impeller, wherein a round block is fixedly connected to the center of the impeller, semicircular blocks are symmetrically arranged in the inner cavity of the round block, a stud is sleeved in the inner cavity of each semicircular block, the outer wall of the stud is in threaded connection with the round block, an inner rod is symmetrically arranged in the inner cavity of each semicircular block, and a bearing is sleeved on the outer wall of the inner rod.

Preferably, the inner cavity of the round block is provided with a groove, one side of the semicircular block is fixedly connected with an inner block, the inner block is made of rubber, and the outer wall of the inner block is in interference connection with the groove.

Preferably, one end of the stud is fixedly connected with a support block.

Preferably, the number of the studs is four.

Preferably, the number of the bearings is four.

Compared with the prior art, the utility model has the beneficial effects that: run through the semicircle piece through the double-screw bolt, carry out threaded connection through rotating messenger double-screw bolt and circle piece, can fix the semicircle piece at the circle piece inner chamber, then cup joint the circle piece at the bull stick outer wall, through the rotation reducing wear of bearing, can dismantle simultaneously, conveniently replace the part that damages, can replace the damage part, need not replace completely, can save the loss of impeller, reduce holistic working cost.
