Synchronizer

Technical Field

The invention relates to the technical field of fans, in particular to a synchronizer.

Background

Conventional air valve synchronizers are purely manually controlled or manually controlled electric actuator controls. The manual control is to adjust the required angle according to the required angle manually, and the air valve can not be opened or closed automatically. The air valve controlled by the manual control electric actuator is also opened or closed manually according to needs, and the air valve cannot be automatically opened or closed by air flow. The air valve has large wind resistance, and is very unfavorable for the axial flow fan with low wind pressure.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Hereinafter, a synchronizer according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, a synchronizer according to an embodiment of the present invention includes: a rotating shaft 100, a turntable 200.

Specifically, the outer circumferential wall of the rotary shaft 100 has a plurality of annular grooves 101 arranged at intervals in the axial direction of the rotary shaft 100, and the rotary shaft 100 has a first central through hole 102 penetrating the rotary shaft 100 in the axial direction of the rotary shaft 100.

The rotary disc 200 is connected to one end of the rotary shaft 100, a plurality of recesses 201 are formed in the outer circumferential wall of the rotary disc 200 and are evenly spaced along the circumferential direction of the rotary disc 200, a second central through hole 202 is formed in the rotary disc 200 and penetrates through the rotary disc 200 along the axial direction of the rotary disc 200, and the second central through hole 202 is coaxial with the first central through hole 102.

Advantageously, the synchronizer further comprises a mounting bracket 300, the mounting bracket 300 is arranged on the turntable 200, the mounting bracket 300 is provided with a plurality of mounting claws 301 corresponding to the plurality of notches 201 one by one, and each mounting claw 301 is matched in each corresponding notch 201.

Advantageously, each notch 201 passes through the carousel 200 in the axial direction of the carousel 200. Each notch 201 includes a rectangular opening portion and a semicircular bottom portion. The number of the plurality of annular grooves 101 is two.

Axial flow fans generally consist of a plurality of blades, and when the fan works, theoretical wind advances in the form of the operating frequency wave of the fan blades, and high-pressure areas and low-pressure areas are distributed in a staggered manner on the rotating plane of the fan. The wind pressure influence on the wind valve blade is different and is periodically fluctuated. The rotary self-operated air valve synchronizer is used for evenly distributing the force borne by each air valve blade and enabling the air valve blades to be opened stably.

According to the synchronizer provided by the embodiment of the invention, a self-operated mechanism design is adopted, electric or pneumatic control is not provided, the synchronizer is completely controlled by airflow, when the fan is started, the air valve is automatically opened, and when the fan is closed, the air valve is also automatically closed.

According to the synchronizer provided by the embodiment of the invention, the rotary type synchronization mechanism is adopted, the resistance is small, the structure is compact, the gap is small, and the impact wave influence formed when the fan blade rotates can be effectively overcome. The wind power generator has the advantages of low noise, low wind resistance and high efficiency.
