Description
Technical field
The utility model is related to a kind of air-conditioner set wind turbine more particularly to a kind of rail vehicle air conditioner group wind turbine sawtooth leaves
Wheel.
Background technology
Air-conditioning draught fan is a kind of new, energy saving, high efficiency, speed variable, low-noise centrifugal ventilation machine, the type wind turbine knot
Structure is compact, easy for installation, small, air quantity is big, pressure is high, with small vibration, adapted three-phase regulator or frequency converter, can carry out stepless
Speed governing is the industries such as air-conditioning, purification ideal especially suitable for the ventilation place that noise requirements are tight, air quantity excursion is big
Auxiliary products.Impeller is vital component in air-conditioning draught fan, and existing air-conditioner set draught fan impeller was using
Following shortcoming is primarily present in journey：First, during the work time, impeller uses the blade of vertical bar shaped substantially, and wind effect is poor,
Defeated wind efficiency is low, and stability is poor, easily generates noise；2nd, existing impeller blade end is than sharp, in the mistake that repair is replaced
Hand is easily scratched in journey, repair is inconvenient, poor safety performance；3rd, existing impeller blade root is more weak, structural strength
Difference, usage time grown it is easy fracture, service life is short, four, due to existing impeller blade it is non-dismountable, once it is single
Blade, which is damaged, to be needed to replace entire impeller, and dismounting is inconvenient, and replacement cost is high.
Utility model content
Technical problem to be solved in the utility model is：There is provided a kind of wind effect good air-conditioning draught fan impeller
Structure.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：Rail vehicle air conditioner group wind turbine
Sawtooth impeller, including：Wheel disc and the axis hole being arranged in the middle part of wheel disc, are evenly arranged with several fixed spiral shells on the outside of the wheel disc
Set, one end of spiral vane are connected with fixed swivel nut by fixing bolt, are set on the other end of the spiral vane
The arc panel of downward bending is equipped with, several zigzag openings are provided in the upper end of the spiral vane, in the spiral shape
Blade handling are provided on one end that blade is connected with fixing bolt and grab block, are connected in the spiral vane with fixing bolt
One end both sides connect are respectively arranged with cambered surface reinforcing rib.
The utility model has the advantages that：Above-mentioned rail vehicle air conditioner group wind turbine sawtooth impeller, structure novel, when beautiful
Still, blade uses helical structure, and several zigzag openings are opened up in blade upper end, make impeller entirety wind effect good, defeated wind
Efficient, stability is good, low noise, and blade tip is additionally provided with the arc panel of downward bending, can have during replacement is repaired
Effect prevents sharp blade tip from scratching the hand of staff, and root of blade is strengthened using cambered surface reinforcing rib, and structure is strong
It spends, is not susceptible to fracture, service life is long, and bolt and the single connection of wheel disc is respectively adopted in blade, and is set in root of blade
Block is grabbed in handling, can carry out independent dismounting and change to individual blade, convenient disassembly, and replacement cost is low.
Description of the drawings
Fig. 1 is the structure diagram of the utility model rail vehicle air conditioner group wind turbine sawtooth impeller.
In figure：1st, wheel disc, 2, axis hole, 3, fixed swivel nut, 4, spiral vane, 5, fixing bolt, 6, arc panel, 7, sawtooth
Shape opening, 8, blade handling grab block, 9, cambered surface reinforcing rib.
Specific embodiment
The particular content of the utility model is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, rail vehicle air conditioner group wind turbine sawtooth impeller, including：Wheel disc 1 and it is arranged on the middle part of wheel disc 1
Axis hole 2, several fixed swivel nuts 3 are evenly arranged in the outside of the wheel disc 1, and one end of spiral vane 4 passes through fixing bolt 5
It is connected with fixed swivel nut 3, the arc panel 6 of downward bending is provided on the other end of the spiral vane 4, in the spiral shell
The upper end of rotation shape blade 4 is provided with several zigzag openings 7, in one end that the spiral vane 4 is connected with fixing bolt 5
On be provided with blade handling grab block 8, be respectively arranged in one end both sides that the spiral vane 4 is connected with fixing bolt 5
Cambered surface reinforcing rib 9.
Above-mentioned rail vehicle air conditioner group wind turbine sawtooth impeller, structure novel, beautiful fashion, blade use spiral shape knot
Structure opens up several zigzag openings in blade upper end, makes that impeller entirety wind effect is good, and defeated wind is efficient, and stability is good, noise
Low, blade tip is additionally provided with the arc panel of downward bending, and sharp blade tip is can effectively prevent during replacement is repaired
The hand of staff is scratched, root of blade is strengthened using cambered surface reinforcing rib, and structural strength is good, is not susceptible to fracture, make
With long lifespan, bolt and the single connection of wheel disc is respectively adopted in blade, and in root of blade handling is set to grab block, can be to single leaf
The independent dismounting and change of piece progress, convenient disassembly, replacement cost are low.
