Description

Technical Field

[0001] This utility model relates to the field of wind tunnel design and research technology, and more specifically to an air duct for an entertainment wind tunnel. Background Technology

[0002] The entertainment wind tunnel combines aerodynamic principles with entertainment project design, using high-powered fans to generate stable high-speed airflow (usually 40-60 meters per second) to "blow" the participants into the air and suspend them, simulating the feeling of free fall during skydiving or weightlessness in space. Currently, existing recreational wind tunnels adopt a fixed vertical wind tunnel structure, which has high requirements for the load-bearing capacity of the bottom of the wind tunnel, resulting in high construction and operation costs, large energy consumption, and high investment costs, which is not conducive to more comprehensive promotion and application. Furthermore, existing recreational wind tunnels are limited to indoor or outdoor use, and their practicality needs to be improved.

[0003] Therefore, how to provide an entertainment wind tunnel that can save energy, reduce operating costs, is more practical, and combines education and entertainment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides an entertainment wind tunnel air duct, which aims to solve one of the problems in the above-mentioned background technology, and can save energy, reduce operating costs, and is more practical, combining education and entertainment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An entertainment wind tunnel air duct includes: The base contains a Q-type main propulsion duct and a Q-type booster duct. The Q-type booster duct is connected to the Q-type main propulsion duct. The ends of the Q-type booster duct and the Q-type main propulsion duct that are far apart from each other are both set as aerodynamic supply ends. The aerodynamic supply ends of the Q-type main propulsion duct are equipped with a medium-speed fan and a high-speed fan in sequence. The aerodynamic supply ends of the Q-type booster duct are also equipped with a medium-speed fan and a high-speed fan in sequence. The Q-type booster air duct is provided in three parts, and the airflow of the three Q-type booster air ducts converges with the airflow of the Q-type main booster air duct at one point. The central wind tunnel indoor flight air duct is located at the center of the base and at the intersection of the Q-type main thrust air duct and the Q-type booster air duct, and is connected to the Q-type main thrust air duct and the Q-type booster air duct. The system includes a large-circulation recirculation air duct and a half-circulation small-circulation recirculation air duct, both of which are mounted on the base. The large-circulation recirculation air duct is connected to the flight air duct inside the central wind tunnel via the Q-type main thrust air duct to form an O-type large circulation. The half-circulation small-circulation recirculation air duct is connected to the flight air duct inside the central wind tunnel via the Q-type booster air duct to form an O-type half-circulation small circulation.

[0006] Furthermore, the inner diameter of the Q-type main propulsion duct is larger than the inner diameter of the Q-type booster duct. Jet pipes are provided on both the Q-type main propulsion duct and the three Q-type booster ducts. The jet pipes are located between the medium-speed fan and the high-speed fan. N jet pipes are symmetrically arranged on both the Q-type main propulsion duct and the Q-type booster duct, where N≥2.

[0007] Furthermore, three half-loop return air ducts are provided corresponding to the Q-type booster air duct, and the three half-loop return air ducts are all connected to the Q-type booster air duct and the central wind tunnel indoor flight air duct to form an O-type half-loop.

[0008] Furthermore, both the air supply end of the Q-type booster duct and the Q-type main booster duct are equipped with an airflow backflow valve, which can be configured as a multi-curtain type or a multi-width type.

[0009] Furthermore, the Q-type main propulsion duct, the three Q-type booster ducts, the large circulation return air duct, and the three half-stroke small circulation return air ducts are arranged in a cross-shaped symmetrical configuration.

[0010] Furthermore, decorative rocket heads are provided at the top of both the central wind tunnel indoor flight air duct and the half-path small circulation return air duct.

[0011] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an entertainment wind tunnel air duct. By setting up a large circulation return air duct connected to the Q-type main propulsion air duct and the central wind tunnel indoor flight air duct to form an O-type large circulation, and a half-stroke small circulation return air duct connected to the Q-type booster air duct and the central wind tunnel indoor flight air duct to form an O-type half-stroke small circulation, simulated flight, wingsuit flight or skydiving training can be carried out in the central wind tunnel indoor flight air duct and the half-stroke small circulation return air duct. Outdoor flight can also be carried out at the external connection of the Q-type main propulsion air duct return air duct. By combining the O-type large circulation with the O-type half-stroke small circulation, the "air energy" involved in the operation can be circulated infinitely to achieve energy saving. The airflow in the O-type circulation is smooth and has little energy loss, low wind resistance and low noise. This entertainment wind tunnel utilizes multi-loop air movement to recover and reuse airflow power, thereby saving energy and reducing operating costs, while also being both educational and entertaining.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figure 1-8 This utility model discloses an entertainment wind tunnel air duct, comprising: The base 1 contains a Q-type main air duct 2 and a Q-type auxiliary air duct 3. The Q-type auxiliary air duct 3 is connected to the Q-type main air duct 2. The ends of the Q-type auxiliary air duct 3 and the Q-type main air duct 2 that are far apart from each other are both set as aerodynamic supply ends 4.

The aerodynamic supply ends 4 of the Q-type auxiliary air duct 3 are also equipped with medium-speed fans and high-speed fans in sequence. By setting up the Q-type main air duct 2 and the Q-type auxiliary air duct 3, multi-loop air movement is used to recover and reuse airflow power, so as to save energy and reduce operating costs. Three Q-type booster ducts 3 are set up, and the airflow of the three Q-type booster ducts 3 converges with the airflow of the Q-type main booster duct 2 at one point. By setting up three Q-type booster ducts 3, multi-loop air movement is achieved in the recirculation of the Q-type main booster duct 2 and the Q-type booster duct 3, recovering and reusing the airflow power, and reducing the operating cost of the wind tunnel "air energy". The central wind tunnel indoor flight air duct 5 is located at the center of the base 1 and is located at the intersection of the Q-type main thrust air duct 2 and the Q-type booster air duct 3. The large-circulation return air duct 6 and the semi-circulation return air duct 7 are both located on the base 1. The large-circulation return air duct 6 is connected to the central wind tunnel indoor flight air duct 5 through the Q-type main propulsion air duct 2 to form an O-type large circulation. The semi-circulation return air duct 7 is connected to the central wind tunnel indoor flight air duct 5 through the Q-type booster air duct 3 to form an O-type semi-circulation. Through the combination of the O-type large circulation and the O-type semi-circulation, the "air energy" participating in the operation can circulate infinitely to achieve energy saving. The airflow in the O-type circulation is smooth and has little energy loss, low wind resistance, and low noise.

[0017] In this embodiment, the inner diameter of the Q-type main air duct 2 is larger than the inner diameter of the Q-type auxiliary air duct 3. Jet pipes 8 are provided on both the Q-type main air duct 2 and the three Q-type auxiliary air ducts 3. The jet pipes 8 are located between the medium-speed fan and the high-speed fan. N jet pipes 8 are symmetrically arranged on both the Q-type main air duct 2 and the Q-type auxiliary air duct 3, where N≥2. The air intake is increased by setting jet pipes 8.

[0018] In this embodiment, three half-loop return air ducts 7 are provided corresponding to the Q-type booster air duct 3. All three half-loop return air ducts 7 are connected to the Q-type booster air duct 3 and the central wind tunnel indoor flight air duct 5 to form an O-type half-loop.

[0019] In this embodiment, the aerodynamic supply end 4 of the Q-type booster duct 3 and the Q-type main booster duct 2 is equipped with an airflow backflow valve 9, which is configured as a multi-curtain type or a multi-width type. The airflow backflow valve 9 prevents the airflow in the Q-type booster duct 3 and the Q-type main booster duct 2 from flowing backward, thus ensuring the stability of the device.

[0020] In this embodiment, the Q-type main push air duct 2, the three Q-type booster air ducts 3, the large circulation return air duct 6, and the three half-stroke small circulation return air ducts 7 are arranged in a cross-shaped symmetrical configuration.

[0021] In this embodiment, decorative rocket heads 10 are provided on the top of both the central wind tunnel indoor flight duct 5 and the half-path small circulation return duct 7. By providing decorative rocket heads 10, the central wind tunnel indoor flight duct 5 and the half-path small circulation return duct 7 are made to look like rockets ready to be launched, pursuing a realistic effect and enhancing the visual experience.

[0022] In addition, in this embodiment, the specific shape of the connection between the Q-type main thrust duct 2, the central wind tunnel indoor flight duct 5, and the large circulation return duct 6, as well as the Q-type booster duct 3, the central wind tunnel indoor flight duct 5, and the half-path small circulation return duct 7, is an inverted lowercase sigma "σ".

[0023] The section near the top of the central wind tunnel indoor flight duct 5 and the half-range small circulation return duct 7 is set up as an indoor flight section for indoor simulated flight or parachute training.

[0024] When this design is installed outdoors, outdoor simulated flight, wingsuit flight or parachute training is conducted at the recirculation end of the Q-type main thrust duct 2, which is located away from the indoor flight duct 5 of the central wind tunnel in the large circulation return air duct 6. A safety flight interception net 11 is installed at the recirculation end of the Q-type main thrust duct 2 to prevent accidental fall and improve safety.

[0025] The rocket launcher used in this design has a frame structure and can be equipped with an internal elevator, operations work room, power room, and a small number of operational guest rooms for personnel waiting for flight training, making it more practical.
