Description

Novel reverse-flow type tourism wind-tunnel

Technical field

The utility model relates to a kind of wind-tunnel that is used for demonstration flight, training etc.

Background technology

Many vertical wind tunnels that are specifically designed to tourism and amusement are arranged, big, the problems such as energy consumption is high, cost is high, poor visual effect of these wind-tunnel ubiquity noises at present at home and abroad.Owing to there are these problems, make this class wind-tunnel can not build public places such as big commercial center of inlet flow rate and urban park in, thereby cause aspect popular colony and attraction spectators ability, being subjected to great restriction with the closely-related indoor parachuting of such wind-tunnel.Also therefore be affected aspect commerciality operation and the popularization.

Design now has " a kind of mini simple and easy experimental wind tunnel " (Chinese patent application 200620043509) to be made up of housing, exhaust blower, controller and power supply, housing is the inner hollow structure, exhaust blower is installed in an end of housing, to other end air draft, connection one is used to control the controller of described exhaust blower exhaust air rate between the exhaust blower power supply." a kind of annular backflow vertical wind tunnel " (Chinese patent application 200620118281), comprise power system and work hole body, work hole body comprises inlet inlet end, stable section, contraction section, active section and outlet exhaust end, wind-tunnel comprises that also covers in its outer shell, between a circular passage is arranged, power system is blown into air from work hole body inlet inlet end, pass work hole body and blow out from the outlet exhaust end, is back to the inlet inlet end through the circular passage.

Summary of the invention

The purpose of this utility model is at above-mentioned present situation, aims to provide that a kind of cost is low, noise is little, energy consumption is low, good visual effect.Be particularly suitable for building in the novel reverse-flow type tourism wind-tunnel of the big public place of inlet flow rates such as Urban Parks, commercial center, recreation center, theme park, scientific museum.

The implementation of the utility model purpose is, novel reverse-flow type tourism wind-tunnel, inflight phase, Fang Bianyuan, circle change side transition section are arranged, reflux section and stable section, first round corner section, second round corner section, the 3rd round corner section and the 4th round corner section are arranged between adjacent two sections successively, the inflight phase leading portion has diffuser, diffuser is equipped with protection network, back segment is provided with second contraction section, second contraction section loads protection network, the blower fan of two parallel connections is housed between Fang Bianyuan transition section, the circle change side transition section, and reflux section is equipped with air hole, establishes first contraction section in the stable section.

The utility model adopts the silent ventilator of two parallel connections to drive, adopt to the wind-tunnel loop seal, measure such as heat insulation and noise reduction, to reduce the noise total amount of wind-tunnel to the surrounding enviroment radiation; Inflight phase is made with the monoblock type organic glass, has strengthened visual effect; Reflux section adopts air hole, has solved the problem of temperature rise of wind-tunnel inside; The protection network with spring-supported wirerope establishment is adopted at the inflight phase two ends, has improved flight safety and comfortableness; Adopt the single loop recycle design to reclaim flowed energy, reduce the total energy consumption and the construction investment of equipment.

The utility model can be integrated in one functions such as collection amusement, exercise, demonstration, performance, training, can with the heavy construction integrated design; The utility model energy consumption is low, noise is low, small investment, attractive force are strong, can build the big public place of inlet flow rate in, as entertainment city, commercial center, park, tourist attractions, exhibition center, school and private garden etc.

Embodiment

With reference to Fig. 1, the utility model has inflight phase 1, Fang Bianyuan, circle change side transition section 5,7, reflux section 10 and stable section 12, first round corner section 4, second round corner section 8, the 3rd round corner section 11 and the 4th round corner section 14 are arranged between adjacent two sections successively, reflux section 10 is equipped with air hole 9, establishes first contraction section 13 in the stable section 12.The direction of arrow is airflow direction among the figure.

With reference to Fig. 2, the area of section of first round corner section 4 becomes the blower fan 6 that two parallel connections are housed between circle transition section 5, the circle change side transition section 7 less than the area of section of second round corner section 8 in the side.

With reference to Fig. 3, the area of section of the 4th round corner section 14 is less than the area of section of the 3rd round corner section 11, and stable section 12 leading portions are established first contraction section 13 that sectional area dwindles gradually.

With reference to Fig. 4, the area of section of first round corner section 4 is less than the area of section of second round corner section 8, and the sectional area of inflight phase 1 is significantly smaller than the sectional area of reflux section 10.Inflight phase 1 leading portion has diffuser 3, and diffuser is equipped with protection network, and back segment is provided with second contraction section, 15, the second contraction sections and loads protection network 16, and upper and

lower protection network

3,16 is with spring-supported, by the protection network of wirerope establishment.Reflux section 10 is equipped with air hole 9.

When using the utility model, start the blower fan 6 of two parallel connections, air-flow is through circle change side transition section 7, second round corner section 8 is changed into airflow direction to the right vertically downward by level, flow into again reflux section 10 the 3rd round corner section 11 with airflow direction by changing into level vertically downward left, adjust through stable section 12 again, flow into 13 compressions of first contraction section, thereby quicken, through the 4th round corner section 14 airflow direction is changed into left vertically upward by level, again through second contraction section compression, thereby accelerate to the needed speed of normal flight, enter inflight phase through protection network down 16 with design rate again.Airflow passes inflight phase 1 back is by diffuser 2, diffusion, deceleration, flow into first round corner section 4, airflow direction in first round corner section is by becoming level vertically upward to the right, and air-flow is divided into side's change circle transition sections 5 that two of two-way inflows are arranged in parallel then, flows into the blower fan 6 of two parallel connections again, through supercharging, and obtain to keep the energy that flows and need, with higher pressure flow into two the circle side of changeing transition sections 7 that are arranged in parallel being positioned at the blower fan downstream, through second round corner section 8, inflow reflux section 10.Flow so repeatedly, form the loop circulation.

When circulating current was flowed through air hole 9 places of reflux section 10, a part of air-flow flowed out wind-tunnel automatically, and sucked the extraneous fresh air with amount automatically, carried out gas displacement in this way, kept the pure and fresh degree of the air in the wind-tunnel.
