Description

Technical Field

[0001] The utility model belongs to the technical field of centrifugal fans, in particular to a centrifugal impeller with adjustable impeller angle. Background Art

[0002] Centrifugal impeller is a commonly used fluid conveying component that relies on centrifugal force to accelerate the fluid. It is usually used in equipment such as pumps, fans and compressors. When the fluid passes through the center of the impeller, the rotation of the impeller enables the fluid to gain energy, increase its pressure and speed, and thus transport the fluid to the periphery of the equipment.

[0003] In the currently existing impellers, the blades are mostly fixed and cannot be adjusted. The blade angles cannot be adjusted according to different media to maximize their efficiency, which causes the impeller to do some useless work and leads to a waste of resources.

[0004] To this end, we provide a centrifugal impeller with an adjustable impeller angle to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a centrifugal impeller with adjustable impeller angle, which solves the problem that the existing impeller angle cannot be adjusted by pushing the connecting rod to move through a hydraulic cylinder and utilizing the connecting tube on the surface of the connecting tube to change the angle of the blade.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0032] See also Figure 1-4 The utility model is a centrifugal impeller with an adjustable impeller angle, comprising a fixing component 100, including a fixing seat 101, a guide cover 102 arranged at the end of the fixing seat 101, and a blade 103 arranged inside the guide cover 102;

[0033] The regulating component 200 includes a power assembly 201 disposed inside the air deflector 102 , and a rotating assembly 202 disposed on a side wall of the power assembly 201 .

[0034] Specifically, the power assembly 201 includes a fixed plate 201a disposed inside the air deflector 102, a hydraulic cylinder 201b disposed at the end of the fixed plate 201a, a connecting rod 201c disposed on the outer wall of the hydraulic cylinder 201b, a guide rod 201d disposed at the end of the connecting rod 201c, and a slider 201e disposed at the bottom of the guide rod 201d.

[0035] Furthermore, the rotating assembly 202 includes a connecting tube 202a arranged on the slider 201e, a guide groove 202b opened on the side wall of the connecting tube 202a, a fixed frame 202c arranged outside the connecting tube 202a, a guide rail 202d opened on the fixed frame 202c, and a fixed tube 202e arranged at the end of the fixed frame 202c.

[0036] Among them, the connecting rod 201c is rotatably connected to the hydraulic cylinder 201b, the other end of the connecting rod 201c is rotatably connected to the guide rod 201d, the guide rod 201d is fixedly connected to the slider 201e, the guide rod 201d is slidably connected to the guide rail 202d, the slider 201e is slidably connected to the guide groove 202b, the fixed frame 202c is fixedly connected to the fixed tube 202e, and the end of the fixed frame 202c has no contact with the connecting tube 202a.

[0037] The operation process of this embodiment is as follows: first, the hydraulic cylinder 201b is started to make the hydraulic cylinder 201b push the connecting rod 201c to move, and a guide rod 201d is provided at the other end of the connecting rod 201c, and the guide rod 201d slides in the guide rail 202d in the fixed frame 202c to ensure that the end of the connecting rod 201c, i.e., the guide rod 201d, can be stably translated to one side without deviation. In addition, a slider 201e is also provided at the bottom of the guide rod 201d, wherein the shape of the slider 201e is consistent with the guide groove 202b provided on the surface of the connecting tube 202a. 201c will bring the slider 201e to move to the left, and the guide groove 202b is spirally distributed on the surface of the connecting tube 202a, so when the slider 201e moves, the connecting tube 202a will rotate under the action of the guide groove 202b, and the blade 103 is set on one side of the connecting tube 202a, so as to achieve the purpose of adjusting the angle of the blade 103. In addition, the fixed frame 202c is connected to the air guide cover 102 through the fixed tube 202e, and the width of the fixed frame 202c is greater than the diameter of the connecting tube 202a. This design can not affect the rotation of the connecting tube 202a. Specific embodiment 2

[0039] See also Figure 5 , based on the specific embodiment 1, it also includes a disassembly component 300, including a connecting component 301 arranged at the end of the connecting cylinder 202a, a fixing component 302 arranged inside the connecting component 301, and a driving component 303 arranged inside the fixing component 302;

[0040] The connecting assembly 301 includes a connecting seat 301a disposed at the end of the connecting tube 202a, a fixing groove 301b opened inside the connecting seat 301a, an intrusion tube 301c sleeved inside the connecting seat 301a, and a through hole 301d penetrating the outer wall of the intrusion tube 301c.

[0041] Specifically, the fixing assembly 302 includes a fixing block 302a disposed inside the intrusion tube 301c, a sleeve 302b fixed to the inner wall of the fixing block 302a, a connecting rod 302c sleeved inside the sleeve 302b, and an extension rod 302d disposed on the outer wall of the connecting rod 302c.

[0042] Furthermore, the driving assembly 303 includes a fixed rod 303a arranged inside the intrusion tube 301c, a driving motor 303b arranged at the top of the fixed rod 303a, a driving gear 303c arranged at the driving end of the driving motor 303b, a gear ring 303e arranged on one side of the driving gear 303c, a fixed shaft 303d passing through the inside of the gear ring 303e, and a guide hole 303f passing through the surface of the gear ring 303e; wherein the driving gear 303c and the gear ring 303e are meshingly connected.

[0043] The operation process of this embodiment is as follows: first, the driving motor 303b is used as the driving source of the driving gear 303c. When the driving motor 303b is started, it can drive the driving gear 303c to rotate. Since the outer side of the driving gear 303c is meshed and connected with the gear ring 303e, when the driving gear 303c rotates, it can drive the gear ring 303e to rotate. Among them, a guide hole 303f is opened on the surface of the gear ring 303e to limit the extension rod 302d. When the gear ring 303e rotates, the height of the guide hole 303f changes, thereby changing the height of the extension rod 302d, thereby controlling the height of the connecting rod 302c, and indirectly achieving the control of the movement of the fixed block 302a, wherein the sleeve 302b is used to control the connecting rod 302c. The motion trajectory ensures that it can move stably without deviation. Secondly, when the fixing block 302a extends out of the through hole 301d, it will be stuck in the fixing groove 301b, so that the entire impeller is fixed. The shape of the fixing groove 301b is adapted to the appearance of the fixing block 302a, which can ensure that the fixing block 302a is stuck therein without shaking, thereby ensuring that the impeller can run stably. In addition, if the blades need to be replaced, it is only necessary to control the drive motor 303b to rotate toward the other side, and indirectly control the gear ring 303e to rotate toward the other side, so that the fixing block 302a returns to the inside of the intrusion tube 301c, and then the impeller is taken out to the outside, avoiding the situation where the entire impeller needs to be replaced due to damage to a single blade 103.
