Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of emergency escape and rescue devices, in particular to a low-airspeed slow-drop parachute. Background Art
[0002] When a fire occurs, due to the rapid spread of fire and smoke, traditional escape routes such as stairs are often quickly blocked, making it difficult for residents of high-rise buildings to escape by conventional means. In this case, people often choose to escape from windows, but when the floor height exceeds a certain limit (such as 20 meters), directly jumping down to escape will bring extremely high life risks because the impact force of the ground is far beyond the range that the human body can withstand.
[0003] At the same time, even if the fire truck can arrive at the scene in time, it is difficult for the fire truck to carry out effective direct rescue due to the height limit of high-rise buildings, which further increases the difficulty and risk of escaping from high-rise building fires.
[0004] In order to solve the above problems, it is necessary to develop a technology or equipment that can provide a safe and effective escape method for residents of high-rise buildings in emergency situations. Utility Model Content
[0005] In order to solve the problems existing in the background technology, the utility model provides a low airspeed slow-drop parachute.
[0006] To achieve the above object, the utility model adopts the following technical scheme: a low airspeed slow-drop parachute, comprising a parachute bag, a parachute rope, a main parachute canopy, a fixing plate, a gas generator, a trigger, a safety belt, a gas generator and a buffer protection mechanism;
[0007] The main canopy is connected to the parachute bag through an umbrella rope. A cavity is provided in the main canopy. A fixing plate is fixed in the cavity. The fixing plate is fixedly connected to a gas generator 1. A gas generator 2 is provided in the parachute bag. The gas generator 2 is communicated with a buffer protection mechanism. The buffer protection mechanism is fixedly connected to the parachute bag. A trigger is provided on the outer wall of the parachute bag. The trigger is respectively connected to signals of gas generator 1 and gas generator 2. A safety belt 1 is provided on the parachute bag.
[0008] The buffer protection mechanism includes a safety seat, a protection airbag, and a safety belt;
[0009] The safety seat is fixedly connected to the parachute bag, the lower end of the safety seat is fixedly connected to the protective airbag, the protective airbag is communicated with the second gas generator, and the safety seat is provided with a second safety belt.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1. Improve safety: The rapid inflation and deployment of the main canopy and the activation of the buffer protection mechanism can significantly slow down the user's falling speed in a short period of time, thereby greatly reducing the risk of injury caused by falling from a high altitude. The soft buffer layer provided by the protective airbag further reduces the impact force when in contact with the ground, enhancing the safety of the user.
[0012] 2. Increased stability: The design of using safety belt one to fix the torso and safety belt two to fix the legs increases the user's stability in the air and reduces the occurrence of accidents caused by shaking or instability.
[0013] 3. Quick start: The trigger can start gas generator one and gas generator two at the same time, so that the main canopy and the protective airbag are inflated and deployed almost at the same time, providing timely protection for the user.
[0014] 4. Easy to use: The parachute bag is designed to be easy to carry and the safety belt is easy to adjust, allowing the user to put on and start the parachute quickly and easily.

[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] This embodiment describes a low airspeed slow-drop parachute, including a parachute bag 1, a parachute rope 2, a main parachute 3, a fixing plate 4, a gas generator 5, a trigger 6, a safety belt 7, a gas generator 8 and a buffer protection mechanism;
[0024] The main canopy 3 is connected to the parachute bag 1 through the parachute rope 2. A cavity is provided in the main canopy 3, and a fixing plate 4 is fixed in the cavity. The fixing plate 4 is fixedly connected to a gas generator 5. A gas generator 2 8 is provided in the parachute bag 1. The gas generator 2 8 is communicated with a buffer protection mechanism, and the buffer protection mechanism is fixedly connected to the parachute bag 1. A trigger 6 is provided on the outer wall of the parachute bag 1. The trigger 6 is respectively connected to the gas generator 5 and the gas generator 2 8 signals. A safety belt 7 is provided on the parachute bag 1.
[0025] The buffer protection mechanism includes a safety seat 9, a protection airbag 10, and a safety belt 11;
[0026] The safety seat 9 is fixedly connected to the parachute bag 1 , and the lower end of the safety seat 9 is fixedly connected to the protective airbag 10 . The protective airbag 10 is communicated with the gas generator 8 , and the safety seat 9 is provided with a safety belt 11 .
[0027] The working principle of slow parachute at low airspeed is as follows:
[0028] 1. Preparation: The user first carries the parachute bag 1 on his back and secures his torso with a safety belt 7 to ensure that the parachute bag will not fall off or shift during jumping and falling; at the same time, the user secures his legs with a safety belt 11 to increase stability and safety in the air.
[0029] 2. Open the parachute: When the user is ready to jump, the whole system is started by trigger 6; trigger 6 is connected to the signal of gas generator 1 5 and gas generator 2 8, so the two gas generators are started at the same time (the gas generator is the prior art).
[0030] 3. Inflation of the main canopy: After receiving the signal from the trigger 6, the gas generator 5 will quickly inject the gas stored inside (usually compressed nitrogen or other inert gas) into the cavity of the main canopy 3; the main canopy 3 will quickly unfold due to the injection of gas, forming a large deceleration surface to slow down the user's falling speed.
[0031] 4. The buffer protection mechanism is activated: At the same time, the gas generator 8 will also receive the signal from the trigger 6 and quickly inject the internal gas into the protective airbag 10; the protective airbag 10 is located under the safety seat 9. When the airbag is filled with gas, it will form a soft buffer layer to further reduce the impact force when the user contacts the ground.
[0032] 5. Safely reach the ground: Under the dual effects of the main canopy 3 and the protective airbag 10, the user's falling speed is significantly slowed down, so that he can safely reach the ground; after reaching the ground, the user can unfasten the safety belt 1 7 and the safety belt 2 11 and get out of the parachute bag 1.
[0033] The design of the low-speed slow-descent parachute fully considers the safety and comfort of the user. Through the rapid deployment of the main canopy and the activation of the buffer protection mechanism, it can effectively slow down the user's falling speed in a short period of time and reduce the risk of injury caused by falling from a high altitude.
[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other forms of assembly without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalents of the claims be included in the present invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
