Fan comprises the fluid reaction face of at least one blade, and wherein connects vaned fan hub.Usually for very little fan, blade and fan hub can be made into integral piece.But commercial Application needs larger fan usually, its blade and fan hub can not make integral piece, need between blade and fan hub, install a connection set additional.
The connection set adopted can determine the assembling of fan, key character that running is relevant with maintenance, such as: the adjustment of fan established angle, when not disturbing other blades the replacement of fan blade or fan blade adjustment, be arranged on the replacement of situation lower blade or the adjustment etc. of blade of its running position in equipment at fan, existing connection set is all installed on the fluid surface of fan blade, thus cause the streamline of the fluid surface of blade to be destroyed, the fan performance designed is changed.
Summary of the invention
The invention provides a kind of fan blade connection set and fan thereof, the connection set that it can solve existing fan is arranged on the fluid surface of fan blade, thus cause the streamline of the fluid surface of blade to be destroyed, and the problem that the setting angle of blade also not easily adjusts.
In order to solve the problems of the technologies described above, the technological scheme that fan blade connection set of the present invention adopts is: include body, the middle part of described body is column locating platform, the upper-end surface of this column locating platform is provided with the upper mounting plate of band mounting hole, its lower end surface is provided with the lower installation board of band mounting hole, and the space angle of described upper mounting plate and described lower installation board is α.
In technique scheme, scheme is more specifically: described space angle α is 0 ° ~ 90 °.
Further: described upper mounting plate is for being the centrosymmetric two clamping plates of described column locating platform; Described lower installation board is for being the centrosymmetric two clamping plates of described column locating platform.
Further: described column locating platform is cylindric or is flat column.
The technological scheme that fan of the present invention adopts is: include fan hub and blade, described fan hub is connected by fan blade connection set with described blade, described fan blade connection set, include body, the middle part of described body is column locating platform, the upper-end surface of this column locating platform is provided with the upper mounting plate for the band mounting hole be connected with the petiole of described blade, its lower end surface is provided with the lower installation board for the band mounting hole be connected with described fan hub, the space angle of described upper mounting plate and described lower installation board is α, described space angle α is 0 ° ~ 90 °.
In technique scheme, scheme is more specifically: described upper mounting plate is for being the centrosymmetric two clamping plates of described column locating platform; Described lower installation board is for being the centrosymmetric two clamping plates of described column locating platform; Described column locating platform is cylindric or is flat column.
Further: the petiole of described blade is provided with the attachment hole corresponding with the described mounting hole of described upper mounting plate; Described fan hub is provided with the positioning hole corresponding with the described mounting hole of described lower installation board.
Owing to adopting technique scheme, the present invention compared with prior art, has following beneficial effect:
1, because the middle part of the body of fan blade connection set of the present invention is column structure, can realize easily changing blades installation angle.
2, the petiole stretched out due to upper mounting plate of the present invention and fan blade blade root position is connected, and avoids being installed on the fluid surface of blade, can not destroy the streamline of the fluid surface of blade.
3, fan structure of the present invention is simple, and its blades installation and convenient disassembly, cost is low, is easy to popularization and application.
Accompanying drawing explanation
Fig. 1 is the structural representation of this fan blade connection set.
Fig. 2 is the stereogram of this fan blade connection set.
Fig. 3 is the plan view of this fan blade connection set.
Fig. 4 is the structural representation of this fan.
Embodiment
Below in conjunction with attached Example, the invention will be further described:
This fan blade connection set as depicted in figs. 1 and 2, include body, the middle part of body is column locating platform 1, the upper-end surface of this column locating platform is upper mounting plate 2, this upper mounting plate has 3 mounting holes 3, column locating platform 1 lower end surface is lower installation board 4, lower installation board 4 has 2 mounting holes 5, an entirety between column locating platform 1 and two mounting plates, mounting plate is cut by the upper and lower two ends of Cylindrical object and forms, upper mounting plate 2 is α, α with the space angle of lower installation board 4 is 42.22 °, and this angle is the established angle of fan blade; Upper mounting plate 2 is made up of two clamping plates 2-1 and 2-2, and this two clamping plates is for being column locating platform Central Symmetry; Lower installation board 4 is made up of two clamping plates 4-1 and 4-2, and this two clamping plates is for being column locating platform Central Symmetry, and column locating platform 1 is cylindric.
This fan as shown in Figure 3, include fan hub 6 and blade 7, fan hub 6 is connected by fan blade connection set with blade 7, the petiole 8 of blade 7 is provided with the attachment hole corresponding with the mounting hole 3 of the upper mounting plate 2 of fan blade connection set, petiole 8 and upper mounting plate 2 are threaded connection or rivet, fan hub 6 is provided with the positioning hole corresponding with the mounting hole 5 of the lower installation board 4 of fan blade connection set, and wheel hub 6 and lower installation board 4 are threaded connection or rivet; On the same line, the center that this device can determine the center of the petiole 8 that fan blade 7 is stretched out and fan hub 6 is just on a radial straight line for the symmetry center of two clamping plates 2-1 and 2-2 of the upper mounting plate 2 of fan blade connection set and two clamping plates 4-1 and 4-2 of lower installation board 4 and the symmetry center of column locating platform.The clip slot bottom surface of upper mounting plate and lower installation board just in time coordinates petiole and wheel hub end face respectively, is so also convenient to location and installation.Certainly, the bottom surface of upper and lower clip slot also can be in same plane with the upper and lower surface of column locating platform 1, can alleviate connection set weight like this thus reduce the driving force of fan.
