Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial ceiling fan, and in particular to a novel fan blade support plate and an industrial ceiling fan blade with the same. BACKGROUND

[0002] In the industrial field, industrial ceiling fans are widely used for ventilation and cooling in large spaces such as factories and warehouses. Currently, the commonly used support plate structure of industrial ceiling fan blades is a traditional flat metal plate, which is connected to the fan blade and the ceiling fan main shaft through bolts. The principle of this support plate is to use its rigidity to transfer the centrifugal force and other loads generated by the fan blade to the ceiling fan main shaft, maintaining the stable operation of the fan blade. The manufacturing process mainly involves cutting and stamping the metal plate, and then drilling holes to meet the connection requirements. In addition, some existing technologies will spray a rust-proof coating on the surface of the support plate to improve its service life. Related technologies can refer to the published patent document (CN201920119787.1), which describes a support plate structure for industrial ceiling fan blades similar to the above common structure.

[0003] Firstly, the strength and rigidity of the traditional flat support plate are limited, and it is difficult to effectively resist the large centrifugal force and vibration generated by the fan blade during high-speed operation of the industrial ceiling fan, which can easily cause the support plate to deform or even break, affecting the safety and stability of the ceiling fan. Secondly, the connection method of the existing support plate makes the fan blade installation and disassembly more cumbersome, and a lot of time and labor cost is required for fan blade maintenance and replacement. Thirdly, the existing support plate does not fully consider the aerodynamic factors in the design, which increases air resistance during the operation of the ceiling fan, reduces the ventilation efficiency of the ceiling fan, and also generates a lot of noise.

[0006] Two inwardly recessed and mutually parallel clamping grooves are formed in the middle position of the arc face along the length direction thereof, and a guide strip is formed between the two clamping grooves. A plurality of through holes penetrating the wall thickness of the support plate body are uniformly formed in the guide strip along the length direction thereof.

[0007] In order to facilitate the assembly of the new fan blade support plate, the connecting part between the side end surface and the arc surface and the horizontal surface adopts a circular arc transition.

[0008] In order to facilitate the realization of clamping, the width of the guide bar is greater than the width of the clamping groove;

[0009] Further, the width of the clamping groove gradually decreases from the top end to the bottom end;

[0010] Further, the connecting part between the top end of the clamping groove and the arc surface adopts a circular arc transition.

[0011] The utility model also provides an industrial ceiling fan blade, including the blade main part, the blade main part one end is fixed with above -mentioned new type fan blade support plate.

[0012] In order to facilitate the realization of the dismounting of the blade main body and the fan blade support plate, the blade main body is arc structure, and the blade main body has a jack that can be inserted into the support plate body, and a plurality of fixing holes corresponding to the through hole of the support plate body are formed on the surface of the blade main body, and the fixing hole and the through hole are fixed by a screw.

[0013] In order to guarantee the effectiveness and stability of the assembly of the blade main body and the fan blade support plate, the blade main body has an inner bottom surface that can be attached to the horizontal surface of the support plate body, an inner top surface that can be attached to the arc surface of the support plate body, and two inner baffles that can be attached to the two side end surfaces of the support plate body, and the inner top surface has a group of clamping strips that can be inserted into the clamping groove, and a guide groove for inserting the guide bar is formed between the two clamping strips.
