Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of pressure buffer being applicable to large-scale vertical pivot blower fan.
Background technique
Wind-power electricity generation is a kind of novel device utilizing the natural resources exploitation energy, large-scale vertical pivot blower fan comes into operation in new exploitation of energy resources, but its critical piece shutter door is when mutually changing with contrary wind state with the wind, open and-shut mode also can change fast, shutter door bursts open or suddenly closes and all can produce the shock with blade frame, cause each parts damages, also can produce certain noise simultaneously.
Model utility content
The purpose of this utility model causes shock to blade frame, damage equipment parts for shutter door flip-flop state in existing large-scale vertical pivot blower fan, and the noise problem produced, provide a kind of can a kind of pressure buffer of large-scale vertical pivot blower fan.
The utility model is achieved through the following technical solutions: pressure buffer two ends are located between blade frame and hinge door, comprise connecting ring, cylinder, import/exhaust hole, adjusting knob, piston, seal ring and connecting rod, described connecting ring is connecting ring A and connecting ring B, lay respectively at the two ends of buffer, connecting ring A is connected on blade frame, cylinder is welded on connecting ring A, import/exhaust hole is provided with connecting ring A adjacent position, import/exhaust hole is provided with adjusting knob, connecting rod is connected with piston and is arranged in cylinder, piston is provided with seal ring, the connecting rod the other end is welded on connecting ring B, connecting ring B is connected with hinge door.
As further improvement of these options, described cylinder is provided with multiple import/exhaust hole.
The utility model has the following advantages compared to existing technology: the utility model is used in large-scale vertical pivot blower fan, when mutually changing between with the wind and against the wind, the state of shutter door changes suddenly, by pressure buffer, utilize the effect of atmospheric pressure effectively can alleviate the shock of shutter door and blade frame to the damage of each parts and noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, pressure buffer two ends are located between blade frame 1 and hinge door 2, comprise connecting ring, cylinder 7, import/exhaust hole 11, adjusting knob 10, piston 8, seal ring 9, connecting rod 5, it is characterized in that: described connecting ring is connecting ring A6 and connecting ring B4, lay respectively at the two ends of buffer, cylinder is welded on connecting ring A6, import/exhaust hole 11 is provided with connecting ring A6 adjacent position, import/exhaust hole 11 is provided with adjusting knob 10, connecting rod 5 is connected with piston 8 and is arranged in cylinder 7, piston 8 is provided with seal ring 9, connecting rod 5 the other end is welded on connecting ring B4.
Connecting ring A6 is connected with blade frame 1, connecting ring B4 is connected with hinge door 2, blade frame 1 is connected by hinge 3 with hinge door 2, when state with the wind, shutter door 2 is in closed condition, piston 8 is in the innermost portion of cylinder 7, when going to suddenly against the wind, shutter door 2 bursts open, as status in Fig. 1, connecting ring 4 and piston 8 are stretched out fast, negative pressure is produced in cylinder 7, the speed that hinge door 2 is opened slows down, reduce to impact, now cylinder 7 internal air pressure is less than external atmosphere pressure, import/exhaust hole will auto-admission, reduce pressure reduction, hinge door 2 is made to continue to open, until desired location, on the contrary, when contrary wind state, hinge door 2 is in open mode, suddenly go to the wind, hinge door 2 is closed suddenly, and connecting ring 4 is extruded with the direction of piston 8 to connecting ring 6, and piston 8 is to cylinder 7 internal motion, malleation is produced in cylinder 7, stop hinge door 2 quick closedown, simultaneously because cylinder 7 air pressure inside is greater than ambient pressure, import/exhaust hole is outwards vented, hinge door continues to close, until close completely, pore place is provided with adjusting knob, can regulate the speed of inlet and outlet as required.
Claims (2)
1. a pressure buffer, it is characterized in that, described pressure buffer two ends are located between blade frame and hinge door, comprise connecting ring, cylinder, import/exhaust hole, adjusting knob, piston, seal ring and connecting rod, described connecting ring is connecting ring A and connecting ring B, lay respectively at the two ends of buffer, connecting ring A is connected on blade frame, cylinder is welded on connecting ring A, import/exhaust hole is provided with connecting ring A adjacent position, import/exhaust hole is provided with adjusting knob, connecting rod is connected with piston and is arranged in cylinder, piston is provided with seal ring, the connecting rod the other end is welded on connecting ring B, connecting ring B is connected with hinge door.
2. a kind of pressure buffer as claimed in claim 1, it is characterized in that, described cylinder is provided with multiple import/exhaust hole.
