Description

Industrial ceiling fan

Technical field

The utility model relates to a kind of fan, and more particularly, it relates to a kind of industrial ceiling fan.

Background technology

Existing large scale industry ceiling fan, its blade does not have tens meters to tens meters not etc., electric machine rotation drives blade propeller running, the angled cutting air movement that does of blade and horizontal plane, thereby generation wind-force, because the flabellum average physique of Industrial fan is larger, it is in the time of work, can send larger noise, existing industrial ceiling fan comprises the connected fixed disk of rotor and is connected to the blade on fixed disk.

By retrieval, the patent that Chinese Patent Application No. is 201120266227.2 discloses a kind of blade for industrial ceiling fan, and this blade profile is crescent shape, hollow setting in blade is provided with guide groove in cavity upper wall, is provided with guide rail on fixed disk, when fixing, gathering sill is inserted in guide rail, then fix with bolt, owing to being cavity between the upper wall of cavity and lower wall, and blade wall has larger span, connect unstablely, easily produce vibrations, make a noise etc.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of noise little, the industrial ceiling fan of stable connection.

For achieving the above object, the utility model provides following technical scheme: a kind of industrial ceiling fan, comprise motor, the fixed disk being connected with rotor, on described fixed disk, be provided with fixed bar, on described fixed bar, be fixed with blade, described blade profile is hollow crescent shape, described blade comprises upper wall and lower wall, between described upper wall and lower wall, be provided with connecting plate, described connecting plate respectively with upper wall, lower wall is fixedly connected with, described connecting plate quantity is two and is symmetrical arranged, described connecting plate middle part is provided with depressed area, on described fixed bar, be provided with the projection coordinating with described depressed area, described depressed area is slidably arranged in projection.

For fear of because of the excessive shock conditions causing of span between blade upper wall and lower wall, between upper wall and lower wall, be provided with connecting plate, to between upper wall and lower wall, link together, avoid upper wall and lower wall appearance vibrations in fan rotation process, produce noise, on connecting plate, be provided with depressed area, on fixed bar, be provided with the projection coordinating with depressed area simultaneously, when installation, alignd with projection in depressed area, then depressed area is slipped in projection, at this moment with bolt, blade is connected with fixed bar again, blade will firmly be fixed on fixed bar like this, simultaneously, depressed area and convex inner walls are close to, so when blade working, can mutually not shake generation noise.

Preferably, the opening of described depressed area is less than bottom.

Depressed area can be stuck in projection, make the two connection tightr, and arrange like this and can make connecting plate there is stronger elasticity, can increase the mechanical property of blade.

Preferably, the afterbody of described blade is provided with deflector, on described deflector, is provided with fixed block, is provided with the opening coordinating with described depressed area on described fixed block, and insert in opening described depressed area.

Deflector is set can increase the service behaviour of blade, and the fixed block coordinating with depressed area is set simultaneously on blade, makes deflector tight with being connected of blade, can closely not occur vibrations and noise because connect at work.

Preferably, described fixed bar length is described length of blade 1/5.

Because the length span of blade is large, and work time has larger rotating speed, to this, in the time of fixed blade, need to increase constant intensity, to this, when fixed bar is length of blade 1/5 time, can meet blade trouble free service under maximum (top) speed.

In sum, the present invention has following beneficial effect: by cross section being the connecting plate that connection blade upper wall and lower wall are set in hollow meniscate blade, strengthened the mechanical property of blade, while avoiding blade working, vibrations produce noise simultaneously, blade are connected more stable.

Detailed description of the invention

With reference to accompanying drawing, the utility model embodiment is described further.

As Figure 1-3, a kind of industrial ceiling fan, comprise motor 1, the fixed disk 2 being connected with motor 1 rotor, on described fixed disk 2, be provided with fixed bar 4, on described fixed bar 4, be fixed with blade 3, described blade 3 cross sections are hollow crescent shape, described blade 3 comprises upper wall 6 and lower wall 7, between described upper wall 6 and lower wall 7, be provided with connecting plate 5, described connecting plate 5 respectively with upper wall 6, lower wall 7 is fixedly connected with, for fear of because of the excessive shock conditions causing of span between blade 3 upper walls 6 and lower wall 7, between upper wall 6 and lower wall 7, be provided with connecting plate 5, to between upper wall 6 and lower wall 7, link together, avoid upper wall 6 in fan rotation process to occur vibrations with lower wall 7, produce noise, described connecting plate 5 quantity are two and are symmetrical arranged, described connecting plate 5 middle parts are provided with depressed area 10, on described fixed bar 4, be provided with the projection coordinating with described depressed area 10, when installation, alignd with projection in depressed area 10, then depressed area 10 is slipped in projection, at this moment with bolt, blade 3 is connected with fixed bar 4 again, blade 3 will firmly be fixed on fixed bar 4 like this, described depressed area 10 is slidably arranged in projection, depressed area 10 is close to convex inner walls, when so blade 3 is worked, can mutually not collide and produce vibrations and then produce noise.

As shown in Figure 4, the opening of described depressed area 10 is less than bottom, and depressed area 10 can be stuck in projection, makes the two connection tightr, and arranges like this and can make connecting plate 5 have stronger elasticity, can increase the mechanical property of blade 3.

As shown in Figure 5, the afterbody of described blade 3 is provided with deflector 8, on described deflector 8, be provided with fixed block 9, on described fixed block 9, be provided with the opening coordinating with described depressed area 10, insert in opening described depressed area 10, and deflector 8 is set can increase the service behaviour of blade 3, and the fixed block 9 coordinating with depressed area 10 is set simultaneously on blade 3, make deflector 8 tight with being connected of blade 3, can closely not occur vibrations and noise because connect at work.

Described fixed bar 4 length are 1/5 of described blade 3 length, because the length span of blade 3 is large, and when work in, has larger rotating speed, to this, in the time of fixed blade 3, need to increase constant intensity, to this, when fixed bar 4 be blade 3 length 1/5 time, can meet blade 3 trouble free service under maximum (top) speed.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model. It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
