Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of parachute training equipment, specifically relating to a parachute training device. Background Technology
[0002] A skydiving wind tunnel is a vertical wind tunnel that can generate a certain speed of vertical airflow. When a person enters the airflow in a certain posture, they can float freely in the air without any tools, supported by the strong wind. This allows people to make various flying movements in the air by changing their posture and center of gravity, achieving the same effect as real flying.
[0003] The existing skydiving training devices have several drawbacks, including:
[0004] 1. Because the parachute fails to adhere to the wind tunnel wall during ascent and descent, the parachute sways severely during the ride, and excessive swaying could lead to a rapid descent. Furthermore, since the parachute is not in close contact with the wall, its vertical movement relies primarily on wind speed, resulting in a lower weight capacity, and passengers may find the strong winds unbearable.
[0005] 2. The fan blows at an angle towards the passengers, resulting in a poor experience. In extreme cases, such as when the fan blades break, there is a risk of safety accidents.
[0006] 3. Controlling the parachute's upper and lower landing points mainly relies on manually switching the fan power on and off, which may lead to risks such as human error.
[0007] 4. The parachute uses a counterweight to adjust the safety rope for raising and lowering. However, the counterweight cannot be adjusted in time during operation, and its function cannot be realized when the passenger is heavy. Utility Model Content
[0008] The purpose of this invention is to provide a parachute training device. By installing a wind tunnel body on a set equipment base and supplying airflow from bottom to top, a simulated descent operation of a parachute in the wind tunnel body is realized.

Detailed Implementation
[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0029] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0030] Reference Figures 1-3A skydiving training device, comprising:
[0031] The wind tunnel body 1 is a columnar structure and is vertically arranged. An equipment door 2 is provided on the bottom side of the wind tunnel body 1.
[0032] Equipment base 3, which is disposed at the bottom of the wind tunnel body 1, is used to support the wind tunnel body 1;
[0033] A concealed fan 4 is installed in the equipment base 3 and transports airflow to the wind tunnel body 1; and
[0034] The wind tunnel body 1 is equipped with a parachute 5, and the top of the parachute 5 is connected to the fall arrestor 7 on the equipment base 3 by a fall arrestor rope 6.
[0035] A wind tunnel body 1 is installed on a base 3, and a hidden fan 4 is installed in the base 3 to blow air from bottom to top. At the same time, a parachute 5 is installed inside the wind tunnel body 1. The parachute 5 simulates a descent inside the wind tunnel body 1 under the action of wind. In order to achieve a better simulation effect, the parachute 5 is raised and lowered by a fall arrestor rope 6 and a fall arrestor 7, so that the parachute 5 can stably perform simulation operations inside the wind tunnel body 1, thereby improving the effect of skydiving training.
[0036] In actual use, the equipment door 2 provides access for personnel to enter and exit the wind tunnel body 1. The user enters the wind tunnel body 1 from the stairs 22 and securely binds the parachute 5 to the bottom. Then, the parachute 5 is blown from below, thereby simulating the operation of the parachute.
[0037] Preferably, the wind tunnel body 1 is provided with a mounting frame 8 at its upper end, and a pulley group 9 is provided in the middle of the mounting frame 8. The fall arrestor rope 6 passes around the pulley group 9 and is fixedly connected to the top of the parachute 5.
[0038] To enable the upper end of the parachute 5 to be pulled by force, a mounting frame 8 is provided on the upper end of the wind tunnel body 1, and a pulley group 9 is provided on the mounting frame 8. By passing the fall arrestor rope 6 around the pulley group 9 and fixing it to the top of the parachute 5, the upper end of the parachute 5 can be pulled by force. More specifically, the pulley group 9 is located near the center of the wind tunnel body 1, so that the parachute 5 can be placed on the central axis of the wind tunnel body 1 after being pulled by force, ensuring better balance.
[0039] Preferably, the pulley assembly 9 includes a fall arrestor rope fixing mounting position 10 and a top fall arrestor rope pulley 11. The fall arrestor rope 6 passes through the top fall arrestor rope pulley 11 and is fixedly connected to the fall arrestor rope fixing mounting position 10. The middle part of the fall arrestor rope 6 located between the top fall arrestor rope pulley 11 and the fall arrestor rope fixing mounting position 10 is movably connected to a fixed pulley 12 provided at the top of the parachute 5.
[0040] More specifically, the fall arrestor rope fixing installation position 10 in the pulley block 9 is set on the mounting frame 8 to fix the end of the fall arrestor rope 6. At the same time, the fall arrestor rope 6 passes through the top fall arrestor rope pulley 11, and the middle part of the fall arrestor rope 6 located between the top fall arrestor rope pulley 11 and the fall arrestor rope fixing installation position 10 is movably connected to the fixed pulley 12 set on the top of the parachute 5. Thus, the parachute 5 is set on the fall arrestor rope 6 through the sliding connection between the fixed pulley 12 and the fall arrestor rope 6. By controlling the winding of the other end of the fall arrestor rope 6, the winding control of the parachute 5 in the wind tunnel body 1 can be realized.
[0041] Preferably, a laser emitter assembly 13 is provided on the inner wall of the wind tunnel body 1. The laser emitter assembly 13 includes an upper dead center laser sensor receiver 14 and an upper dead center laser sensor emitter 15 located above the wind tunnel body 1, and a lower dead center laser sensor receiver 16 and a lower dead center laser sensor emitter 17 located below the wind tunnel body 1. The upper dead center laser sensor receiver 14 and the upper dead center laser sensor emitter 15 are arranged opposite each other in the diameter direction of the wind tunnel body 1, and the lower dead center laser sensor receiver 16 and the lower dead center laser sensor emitter 17 are arranged opposite each other in the diameter direction of the wind tunnel body 1.
[0042] Because the parachute 5 can be suspended in the wind tunnel body 1 under the pull of the fall arrestor rope 6; however, in order to better control the predetermined position of the parachute 5 in the wind tunnel body 1, a corresponding laser sensor is set to detect the position of the parachute 5 in the wind tunnel body 1, and then control the winding operation of the fall arrestor 7. Specifically, the cooperation between the upper dead point laser sensor receiver 14 and the upper dead point laser sensor transmitter 15 in the laser transmitter assembly 13 realizes the position detection of the upper end of the parachute 5, and the cooperation between the lower dead point laser sensor receiver 16 and the lower dead point laser sensor transmitter 17 realizes the position detection of the lower end of the parachute 5.
[0043] Preferably, the upper end of the wind tunnel body 1 is provided with an air outlet position partition 18, the upper end of the air outlet position partition 18 is provided with a rain cover 19, and the bottom of the air outlet position partition 18 is fixedly connected to the mounting frame 8.
[0044] By providing an air outlet position partition 18 at the upper end of the wind tunnel body 1, the air outlet position partition 18 provides a fixed installation for the rain cover 19. Furthermore, the bottom of the air outlet position partition 18 is fixedly connected to the mounting bracket 8, so that the upper end of the wind tunnel body 1 can achieve both direct overhead shielding and exhaust operation for the area around the bottom of the rain cover 19.
[0045] Preferably, a rolling bearing dust removal assembly 20 is provided on the edge of the parachute 5 near the inner wall of the wind tunnel body 1, and multiple rolling bearing dust removal assemblies 20 are evenly distributed along the circumference of the parachute 5.
[0046] Because the equipment is quite tall and placed outdoors, dust easily accumulates on the inner and outer walls. A rolling bearing dust removal component 20 is installed on the edge of the parachute. By moving the parachute 5 up and down, dust can be removed from the inner wall of the tube while overcoming the sliding friction between the parachute and the inner wall.
[0047] Preferably, a safety elastic net 21 is provided at the bottom of the wind tunnel body 1.
[0048] During the ascent of parachute 5, the fall arrestor 7 will automatically tighten the rope. During the descent, the rope can be automatically pulled out and is in servo mode. When the parachute suddenly falls, the fall arrestor will stop releasing the rope in time. At this time, the person can be slowly lowered by hand. In extremely special circumstances, if the person falls rapidly and the fall arrestor fails, or the safety rope breaks, the parachute breaks, or all three safety measures fail, the person will fall onto the bottom safety elastic net 21 to ensure the person's safety.
[0049] Preferably, the wind tunnel body 1 is a transparent cylindrical structure.
[0050] Setting the wind tunnel body 1 as a transparent cylindrical structure facilitates observation of the internal conditions of the wind tunnel body 1, thereby improving the training effect and safety of parachuting.
[0051] The working principle and process of this utility model:
[0052] The parachute training device provided by this utility model, when in use, involves installing a wind tunnel body 1 on a set equipment base 3, and setting a hidden fan 4 in the equipment base 3 to blow air from bottom to top. At the same time, a parachute 5 is set inside the wind tunnel body 1. The parachute 5 simulates a descent in the wind tunnel body 1 under the action of wind force. In order to achieve a better simulation effect, the parachute 5 is raised and lowered by a set fall arrestor rope 6 and a fall arrestor 7, so that the parachute 5 can stably perform simulation operations inside the wind tunnel body 1, thereby improving the effect of parachute training.
[0053] Furthermore, the fall arrestor rope fixing installation position 10 in the pulley block 9 is set on the mounting frame 8 to fix the end of the fall arrestor rope 6. At the same time, the fall arrestor rope 6 passes through the top fall arrestor rope pulley 11, and the middle part of the fall arrestor rope 6 located between the top fall arrestor rope pulley 11 and the fall arrestor rope fixing installation position 10 is movably connected to the fixed pulley 12 set on the top of the parachute 5. Thus, the parachute 5 is set on the fall arrestor rope 6 through the sliding connection between the fixed pulley 12 and the fall arrestor rope 6. By controlling the winding of the other end of the fall arrestor rope 6, the winding control of the parachute 5 in the wind tunnel body 1 can be realized.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
