Description

Technical Field

[0001] The present invention relates to the technical field of flying probe protection, and in particular to a safety protection device and method for a flying probe. Background Art

[0002] After a disaster (such as searching for survivors in the rubble after an earthquake, or searching for missing ships on the vast ocean), the use of helicopters or other manned aircraft equipped with thermal imaging cameras and other advanced sensor systems can greatly improve search and rescue efficiency.

[0003] These manned aircraft are also usually equipped with safety protection equipment, which consists of components such as parachutes, trigger devices and protective shells. Their working principle is: when an unexpected situation occurs (such as sudden power failure of the manned aircraft), the operator can manually control the trigger device to open the parachute, so that the parachute moves out of the protective shell and comes into contact with the outside airflow to expand. After the parachute expands, it comes into contact with the outside air, slowing down the descent speed of the manned aircraft, thereby achieving safety protection for the personnel.

[0004] However, in actual operation, if the external airflow environment is unstable (for example, there is strong wind), the parachute may be disturbed by the airflow at the moment it moves out of the protective shell, causing the parachute to swing in the direction of the airflow, which will prolong the time it takes for the parachute to open, making it impossible for the parachute to fully unfold and contact the external airflow in the first place. If the parachute opens too slowly, the descent speed of the manned aircraft may not be slowed down in time, thereby increasing the risk of hitting the ground and reducing the survival rate. Summary of the invention

[0005] The present invention adopts the following technical solutions to solve the above technical problems. A safety protection device for a flying detector comprises:

[0006] a first storage shell, wherein the first storage shell is detachably connected to the second storage shell, the first storage shell and the second storage shell are jointly limitedly slidably connected to a sliding seat, and a spring is arranged between the sliding seat and the first storage shell;

The protective films distributed at intervals are all fixed to the side of the second storage shell away from the first storage shell. The protective films distributed circumferentially are all used to protect the parachute. The protective films distributed circumferentially are all squeezed and matched with the parachute.

[0020] Furthermore, it also includes:

[0021] a striking assembly, arranged in the second storage shell, for striking the protective films arranged at intervals, the striking assembly comprising: fixing frames, arranged at intervals, the fixing frames arranged at intervals being all fixedly connected to a side of the second storage shell away from the first storage shell, the fixing frames being provided with sliding grooves, the sliding grooves of the fixing frames being slidably connected with clamping members, the clamping members being in contact with and cooperating with the adjacent protective films;

[0022] The number of the extrusion rods is the same as that of the fixing frames, and they are respectively slidably connected to the adjacent fixing frames. The extrusion rods are slidably matched with the second storage shell, and the extrusion rods are pressed and matched with the sliding ring. A tension spring is arranged between the extrusion rods and the second storage shell. The fixing frame is provided with a third connecting rope for connecting the adjacent extrusion rods and the adjacent clamping member. The fixing frame is provided with a limiting groove, and the cross section of the limiting groove is an arc, which is used to guide the adjacent third connecting rope;

[0023] A limiting assembly is arranged on the second storage shell, and the limiting assembly is used to limit the extrusion rods that are distributed at intervals.

[0031] Furthermore, the clamping member is located directly below the detachable connecting parts of two adjacent protective films.

[0032] Furthermore, the method for using the safety protection device for the flying detector comprises the following steps:

[0033] In the first step, the device is first installed on the manned aircraft. When an unexpected situation occurs in the manned aircraft and the aircraft cannot fly in the air, the driving member drives the extrusion frame to squeeze all the limit members, so that the limit members release the limit of the adjacent extrusion rods;

[0034] In the second step, the extrusion rod pulls the clamping member through the adjacent third connecting rope, so that the clamping member pierces the adjacent protective film during the movement and throws out the traction member;

[0035] The third step is that during the movement of the extrusion rod, all the bayonet pins are squeezed through the sliding ring and all the connecting rods, so that the bayonet pins are separated from the limit of the sliding seat;

[0036] In the fourth step, the sliding seat is squeezed by the adjacent springs, so that the sliding seat drives the attached parts thereon to move upward until the sliding seat fits with the second storage shell, and at this time all the swing frames swing outward to pre-open the parachute;

[0037] Step 5: After the parachute is pre-opened, it is separated from the limits of the two adjacent rotating plates, so that the parachute is fully deployed to protect the manned aircraft;

[0038] Step 6: After the manned aircraft lands smoothly, the driving member drives the extrusion frame to reset and move, and reinserts all the limit members into the second storage shell, and then manually resets the sliding seat. After the sliding seat is reset, all the clamping members and the swing frame are also swung and reset;

[0039] Step 7: After all the clamps and the swing frame are reset, the parachute is stored in the second storage shell, and the two rotating plates on the swing frame are used to fix the parachute, and then the traction member is fixed to all the clamps.

[0040] The beneficial effects of the present invention are as follows: the present invention proposes a new parachute folding method, which aims to optimize the process of rapid deployment of the parachute. Specifically, when the parachute is triggered and unlocked, its lower part will be pre-opened, so that the airflow can actively enter the interior of the parachute. In this way, the parachute will not be separated from the protective shell until it is fully expanded by the airflow. This design ensures that the parachute is in a partially expanded state before it is completely separated from the protective shell, thereby greatly shortening the time required for the parachute to be fully deployed. This design can effectively reduce the problem of parachute deployment delay caused by unstable external airflow (such as strong wind environment), and improve the reliability and safety of the parachute in emergency situations.

[0041] The present invention adopts a method of pre-opening the small guide parachute and throwing it into the air, thereby reducing the molding time of the small guide parachute. Even when encountering strong winds, it can maintain its shape and function, ensuring the smooth deployment of the main parachute. This design can effectively solve the problem that in harsh environments such as strong winds, the small guide parachute is blown away before it is formed, resulting in the main parachute cannot be deployed in time, thereby improving the stability of the small guide parachute during the release process.

DETAILED DESCRIPTION

[0053] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0054] In order to solve the problem that the parachute molding time is prolonged due to the influence of strong wind environment during the opening process of the parachute in the existing safety protection equipment, the present invention designs a new parachute folding method, aiming to take into account how to quickly open the parachute during the winding process. Specifically, when the parachute is triggered and unlocked, the lower part of the parachute is pre-opened so that the airflow can actively enter the inside of the parachute. In this way, the parachute can be separated from the protective shell only after it is fully opened by the airflow. This design ensures that the parachute can maintain a pre-opened state before it is completely separated from the protective shell, thereby shortening the parachute molding time. At the same time, this also prevents the problem of prolonged parachute molding time due to the influence of strong wind environment during the process of separating from the protective shell.

[0055] Embodiment 1: A safety protection device for a flying probe, such as Figure 1-Figure 5 and Fig. 9 and Fig.10 As shown, it includes: a first storage shell 10, the first storage shell 10 is detachably connected to the second storage shell 11, the first storage shell 10 and the second storage shell 11 are jointly limited and slidably connected to a sliding seat 12, and a spring is arranged between the sliding seat 12 and the first storage shell 10; the bayonet pins 13 are arranged at intervals and are all slidably connected to the first storage shell 10, and the bayonet pins 13 arranged at intervals are all limited and matched with the sliding seat 12; the fixed seats 14 arranged at intervals are all fixedly connected to the sliding seat 12, and the fixed seats 14 are rotatably connected to the swing seat 12. The first storage shell 10 and the second storage shell 11 are both limitedly matched with the swing frame 15, and an elastic member 16 is fixedly connected between the swing frame 15 and the adjacent fixed seat 14; the parachute 17 is arranged on the sliding seat 12, and the parachute 17 is located in the first storage shell 10 and the second storage shell 11; the fixing components are consistent in number with the swing frame 15, and are arranged on the adjacent swing frame 15, and are used to fix the parachute 17; the upper part of the parachute 17 is recessed inward, and the parachute 17 shrinks inward circumferentially.

[0056] In the above scheme, the first storage shell 10 and the second storage shell 11 are both made of high-strength steel, and the first storage shell 10 and the second storage shell 11 are both polygonal. The adjacent springs of the sliding seat 12 are in a force storage state when they do not move upward. The second storage shell 11 is composed of a fixed shell and circumferentially evenly distributed limit blocks, and the circumferentially evenly distributed limit blocks are all located in the fixed shell. After the sliding seat 12 moves to contact the lower side of the circumferentially distributed limit blocks in the second storage shell 11 (which is the extreme position of the sliding seat 12), the sliding seat 12 no longer moves upward, thereby preventing the sliding seat 12 from moving out of the second storage shell 11 when it is squeezed by the adjacent springs. The upper sides of all the latches 13 are provided with inclined surfaces, and the elastic member 16 is an elastic dial. The elastic member 16 is composed of a semicircular paddle and two rectangular paddles. When the swing frame 15 does not swing, the adjacent elastic members 16 are in a power storage state. The parachute 17 is composed of an umbrella body 170, a first connecting rope 171 evenly distributed in the circumferential direction, a connecting ball 172, and a second connecting rope 173. The first connecting ropes 171 evenly distributed in the circumferential direction are all fixedly connected to the lower side of the outer side of the umbrella body 170, the connecting ball 172 is fixedly connected to the lower side of the first connecting ropes 171 evenly distributed in the circumferential direction, the second connecting rope 173 is fixedly connected to the lower side of the connecting ball 172, and the lower end of the second connecting rope 173 is fixedly connected to the sliding seat 12. During the use of the umbrella body 170, the staff uses Velcro to shape the umbrella body 170 so that the umbrella body 170 presents Figure 3 Velcro is not shown in the figure.

[0057] like Figure 4 and Figure 5 As shown, the fixed assembly includes: at least two extrusion plates 20, both of which are slidably connected to adjacent swing frames 15; a sliding frame 21, which is slidably connected to the adjacent swing frames 15, the extrusion plates 20 are provided with oblique grooves, the sliding frame 21 is extruded and matched with the oblique grooves in the adjacent extrusion plates 20, a spring is provided between the sliding frame 21 and the adjacent swing frames 15, and the opposite sides of the two adjacent extrusion plates 20 are rotatably connected with rotating plates 22, and the rotating plates 22 are in contact and matched with the parachute 17.

[0058] In the above scheme, when two adjacent rotating plates 22 are close to each other, the outer side of the umbrella body 170 is clamped and fixed, and the two extrusion plates 20 on the swing frame 15 are located on the upper side thereof, ensuring that the range of the umbrella body 170 clamped by the two adjacent rotating plates 22 after pre-expansion is consistent with the range after all the swing frames 15 are swung back to back, ensuring the maximum expansion of the umbrella body 170, the inclined grooves in the two adjacent extrusion plates 20 are V-shaped, and the initial position of the upper side of the sliding frame 21 is located on the back side of the inclined grooves of the two adjacent extrusion plates 20, the rotating plate 22 is located on the upper part of the adjacent swing frame 15, and the side of the rotating plate 22 away from the adjacent extrusion plate 20 is sprayed with a paint that increases friction.

[0059] like Figure 3-Figure 6As shown, it also includes: a sliding ring 30, a sliding groove is provided in the first storage shell 10, the sliding ring 30 is slidably connected in the sliding groove of the first storage shell 10, and a spring is provided between the first storage shell 10 and the sliding ring 30; a connecting rod 31, the number of which is the same as the bayonet 13, is slidably connected to the first storage shell 10, and an oblique groove is provided in the bayonet 13, and the connecting rod 31 is pressed and matched with the oblique groove in the adjacent bayonet 13;

[0060] like Figure 1-Figure 3 As shown, it also includes: a protective film 40, which is distributed circumferentially and detachably connected to each other, the spaced protective films 40 are all fixed to the side of the second storage shell 11 away from the first storage shell 10, the circumferentially distributed protective films 40 are all used to protect the parachute 17, and the circumferentially distributed protective films 40 are all squeezed and matched with the parachute 17.

[0061] In the above scheme, the spring in the slide groove of the first storage shell 10 is used to provide support for the sliding ring 30, and the side of the inclined groove in the pin 13 close to the central axis of the sliding seat 12 is lower than the side away from the central midline of the sliding seat 12, and all the protective films 40 form an easy-to-tear film. When all the protective films 40 are not damaged, the upper side of the second storage shell 11 is blocked.

[0062] Before the manned aircraft performs a travel mission, the user first installs the device to the required working position of the manned aircraft, and then places the external trigger device (which is an electric push rod, which will be located in the slide groove of the first storage shell 10 during use, and the telescopic end of the electric push rod will contact the sliding ring 30) in the first storage shell 10. Before placement, the first storage shell 10 and the second storage shell 11 can be disassembled (and the two can be reinstalled after placement). Through the above-mentioned operating steps, the preparation work before the manned aircraft travel mission is completed.

[0063] After completing the preparations for the manned aircraft to go out on a mission, the manned aircraft is flying normally in the air. When the power of the manned aircraft fails and it cannot continue to fly in the air (this situation is only an example and is not limiting), the user presses the sliding ring 30 downward through the external trigger device (the sliding ring 30 squeezes the adjacent springs during the movement, and the trigger device resets itself after use), so that the sliding ring 30 drives all the connecting rods 31 to squeeze the inclined grooves of the adjacent latch pins 13 respectively, so that all the latch pins 13 move backwards.

[0064] As all the latches 13 move backward, the limit on the sliding seat 12 is released, the sliding seat 12 and its accessory parts are squeezed upward by the adjacent springs, and the umbrella body 170 is squeezed into a folded state first. As the sliding seat 12 continues to move upward, the umbrella body 170 is disengaged from the Velcro, and the fixation of the umbrella body 170 is released.

[0065] After the sliding seat 12 drives all the swing frames 15 to move until the upper sides of all the swing frames 15 are in contact with the adjacent protective films 40 respectively, the protective films 40 are broken to expose the umbrella body 170 to the external environment. After the sliding seat 12 moves to be limited by the second storage shell 11, all the swing frames 15 are no longer in contact with the inner wall of the second storage shell 11. At this time, all the elastic members 16 drive the adjacent swing frames 15 to swing outward respectively, simulating the state of flowers blooming, and flipping the lower part of the outer side of the umbrella body 170 outward, actively opening part of the umbrella body 170, thereby shortening the opening time of the umbrella body 170 and allowing the airflow to enter the umbrella body 170 faster and open it.

[0066] After the umbrella body 170 is partially opened, external air flows into the umbrella body 170, causing the inside of the umbrella body 170 to expand. When the umbrella body 170 expands to a degree sufficient to break away from the clamping force applied to the umbrella body 170 by all two adjacent rotating plates 22, the umbrella body 170 drives the upper sides of the first connecting rope 171, the connecting ball 172 and the second connecting rope 173 to move toward the side away from the second storage shell 11.

[0067] After the umbrella body 170 is away from the second storage shell 11, the airflow continues to enter the umbrella body 170 and causes it to continue to expand. Fig. 9 After reaching the state of the middle position, the parachute body 170 applies a dragging force to the first connecting rope 171, the connecting ball 172 and the second connecting rope 173, thereby dragging the manned aircraft and reducing the falling speed of the manned aircraft, thereby achieving safety protection of the manned aircraft.

[0068] After the manned aircraft has landed safely, the user will first inspect the manned aircraft. After completing the inspection of the manned aircraft, the user will first separate the second storage shell 11 from the storage shell 10, and then press the sliding seat 12 downward until its lower side contacts the inclined surfaces on the upper sides of all the pins 13 (in the process of the sliding seat 12 moving downward, all the swing frames 15 swing inward and the adjacent elastic members 16 bend). The sliding seat 12 continues to move downward, squeezing all the pins 13 inward. When the sliding seat 12 slides enough for all the pins 13 to be inserted therein, the sliding seat 12 stops moving, and all the pins 13 are inserted into the sliding seat 12, thereby achieving the resetting of the sliding seat 12.

[0069] After the sliding seat 12 is reset, the staff folds the umbrella body 170 in half again, so that the umbrella body 170 is Figure 2 and Figure 3After it is in the state, the staff will then insert the lower side of the outside of the umbrella body 170 between the two rotating plates 22 on all the swing frames 15 in turn. The insertion process is as follows: the staff presses the sliding frame 21 downward (the adjacent springs are squeezed during the movement of the sliding frame 21), and the sliding frame 21 squeezes the inclined grooves in the two adjacent squeezing plates 20, so that the two adjacent squeezing plates 20 drive the adjacent rotating plates 22 to move backwards, and then insert the lower side of the outside of the umbrella body 170 between the two adjacent rotating plates 22, and then the staff releases the sliding frame 21, and the sliding frame 21 is squeezed by the adjacent springs to move upward and reset, so that the two adjacent rotating plates 22 are close to each other and contact the umbrella body 170 (the actions of subsequent parts can be repeated as above), and then the staff will re-stick the umbrella body 170 to the Velcro to complete the reset and storage of the umbrella body 170.

[0070] After completing the resetting and storage of the umbrella body 170, the staff will reinstall the second storage shell 11 on the upper side of the first storage shell 10, and then replace all the protective films 40. By blocking the upper side of the second storage shell 11 with all the protective films 40, the second storage shell 11 and the first storage shell 10 are kept in a closed environment to prevent mosquitoes or other debris from entering the second storage shell 11 and the first storage shell 10 (this situation is only an example and is not limited), which would cause the umbrella body 170 to be damaged before it is used.

[0071] During use, the parachute in the existing safety protection equipment will first release a small guide parachute, which is used to pull the parachute out of the safety protection equipment and assist in the formation of the parachute. However, in actual use, the small guide parachute is easily affected by the external environment. For example, in windy weather, the small guide parachute may be blown away by the strong wind before it is formed. In this way, the small guide parachute will not be able to help the parachute to form and pull it out of the safety protection equipment in time, which not only increases the time required for the parachute to fully deploy, but may also cause the parachute to fail to open normally, thereby posing a threat to the safety of the user. For this reason, the present invention reduces the forming time and improves the stability by pre-opening the small guide parachute and forming it before throwing it out. In this way, when encountering external interference such as strong winds, the small guide parachute can better maintain its shape and function, ensuring the smooth deployment of the main parachute.

[0072] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 3 , Figure 6-Figure 8 and Fig.10As shown, it also includes: a striking component, which is arranged in the second storage shell 11 and is used to strike the protective films 40 distributed at intervals. The striking component includes: a fixing frame 50, which is distributed at intervals. The fixing frames 50 distributed at intervals are all fixed to the side of the second storage shell 11 away from the first storage shell 10. The fixing frame 50 is provided with a sliding groove. A clamping member 51 is slidably connected in the sliding groove of the fixing frame 50. The clamping member 51 contacts and cooperates with the adjacent protective film 40; an extrusion rod 52, which is consistent with the number of the fixing frames 50 and is slidably connected to the adjacent fixing frames 50 respectively. The extrusion rod 52 is slidably matched with the second storage shell 11, the extrusion rod 52 is extruded and matched with the sliding ring 30, and the extrusion rod 52 is A tension spring is arranged between the second storage shells 11, a third connecting rope 53 for connecting adjacent extrusion rods 52 and adjacent clamping members 51 is arranged on the fixing frame 50, a limiting groove 60 is arranged in the fixing frame 50, and the cross-section of the limiting groove 60 is arc-shaped, which is used to guide the adjacent third connecting rope 53; a limiting component is arranged on the second storage shell 11, and the limiting component is used to limit the spaced extrusion rods 52; the clamping member 51 is located directly below the detachable connecting part of the two adjacent protective films 40; and also includes: a traction member 80, which is arranged on the parachute 17, and the traction member 80 is located in the second storage shell 11, and the spaced clamping members 51 are all used to clamp the traction member 80.

[0073] In the above scheme, the sliding groove of the fixed frame 50 is composed of an inverted U-shaped groove and a straight groove that are connected to each other. The sliding seat 12 is provided with notches with the same number as the clamping member 51, and the middle of the notch of the sliding seat 12 is in the same vertical line as the middle of the clamping member 51. During the movement of the sliding seat 12, the clamping member 51 will not affect the sliding seat 12. The clamping member 51 is composed of a sliding rod and a clamp that are fixed to each other. The initial position of the clamping member 51 is located at the lower part of the fixed frame 50 on the side close to the central axis of the second storage shell 11. The clamp of the clamping member 51 is used to fix the traction member 80. By clamping and fixing the traction member 80 by all the clamping members 51, the pre-opening of the traction member 80 is realized, thereby reducing the time for the traction member 80 to be autonomously opened in the later stage.

[0074] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the limiting assembly includes: limiting members 70, the number of which is consistent with the extrusion rods 52 and is distributed at intervals, and all are slidably connected to the second storage shell 11, and the limiting members 70 are limited by the adjacent extrusion rods 52; a fixing ring 71, which is fixed to the second storage shell 11, and the fixing ring 71 is fixed to all the limiting members 70; an extrusion frame 72, which is slidably connected to the fixing ring 71, and the extrusion frame 72 is extruded and matched with the spaced limiting members 70; a driving member 73, which is fixed to the fixing ring 71, and the telescopic end of the driving member 73 is fixed to the extrusion frame 72.

[0075] In the above scheme, the limit member 70 is composed of a locking block and a pull rope fixedly connected to each other. When the upper side of the limit member 70 contacts the lower side of the adjacent extrusion rod 52, the extrusion rod 52 cannot move downward, and the lower side of the extrusion frame 72 is squeezed and matched with the pull ropes in all the limit members 70. When the extrusion frame 72 squeezes the pull ropes in all the limit members 70, the pull rope pulls the locking block to release the reset of the adjacent extrusion rod 52. The driving member 73 is an electric push rod.

[0076] This embodiment replaces the external trigger device in Embodiment 1 by installing the driving member 73 and its accessory parts, without the need to install other additional parts.

[0077] When the manned aircraft carrying the present device encounters the unexpected situation mentioned in Example 1, the staff controls the telescopic end of the driving member 73 to move downward, and the telescopic end of the driving member 73 drives the extrusion frame 72 to move downward and squeeze the back side of all the limiting members 70, so that all the limiting members 70 move backward and release the limit of the adjacent extrusion rods 52, and all the extrusion rods 52 are pulled downward by the adjacent tension springs.

[0078] Taking the movement process of one of the extrusion rods 52 as an example, when the extrusion rod 52 moves downward, the adjacent clamping member 51 is dragged by the adjacent third connecting rope 53 (the third connecting rope 53 slides along the limiting groove 60 on the adjacent fixing frame 50 during the dragging process, so that the third connecting rope 53 moves along the specified trajectory), so that the clamping member 51 drives the traction member 80 to move upward. After the clamping member 51 moves to contact the connecting part of the two adjacent protective films 40, the two adjacent protective films 40 are actively torn apart, thereby saving the release time of subsequent parts.

[0079] When the clamping member 51 moves to the upper side of the fixing frame 50 and swings outward, the traction member 80 is actively and quickly thrown out, so that the traction member 80 remains stable during the throwing process, thereby reducing the impact of the external environment on the traction member 80. When the clamping member 51 moves along the adjacent fixing frame 50 to the side of the adjacent fixing frame 50 close to the second storage shell 11, the clamping member 51 moves downward. During this process, the squeezing rod 52 moves to contact the sliding ring 30 and squeezes the sliding ring 30 downward, so that the sliding ring 30 drives all the connecting rods 31 to squeeze the adjacent pins 13 respectively, thereby releasing the limit on the sliding seat 12. The subsequent movement process of the sliding seat 12 can repeat the process proposed in Example 1.

[0080] During the movement of the sliding seat 12 , the traction member 80 drives the lower side of the umbrella body 170 to move upward, and pulls out the lower side of the umbrella body 170 , thereby further shortening the molding time of the umbrella body 170 .

[0081] After the manned aircraft lands smoothly, the staff recovers the device. The recovery process is as follows: the staff controls the driving member 73 to drive the extrusion frame 72 to move upward so as not to squeeze all the limit members 70. Then the staff moves all the clamping members 51 to Figure 7 The state in the middle (which is the basic state of the clamping member 51 at this time), and then all the limiting members 70 are reinserted into the second storage shell 11, so that the limiting members 70 resume the limiting position of the adjacent squeezing rods 52.

[0082] After all the clamping members 51 are restored to the basic state, the staff manipulates all the clamping members 51 to clamp the traction member 80 so that the traction member 80 is in the basic state.

[0083] In addition, the present invention also provides a method for using the safety protection device for a flying detector, comprising the following steps:

[0084] In the first step, the device is first installed on the manned aircraft. When an unexpected situation occurs in the manned aircraft and the aircraft cannot fly in the air, the driving member 73 drives the extrusion frame 72 to squeeze all the limiting members 70, so that the limiting members 70 release the limiting of the adjacent extrusion rods 52;

[0085] In the second step, the squeezing rod 52 pulls the clamping member 51 through the adjacent third connecting rope 53, so that the clamping member 51 punctures the adjacent protective film 40 during the movement, and throws out the traction member 80;

[0086] Step 3: During the movement of the squeezing rod 52, all the bayonet pins 13 are squeezed through the sliding ring 30 and all the connecting rods 31, so that the bayonet pins 13 are separated from the limit of the sliding seat 12;

[0087] Step 4: The sliding seat 12 is squeezed by the adjacent springs, so that the sliding seat 12 drives the attached parts thereon to move upward until the sliding seat 12 fits with the second storage shell 11. At this time, all the swing frames 15 swing outward to pre-open the parachute 17.

[0088] Step 5: After the parachute 17 is pre-opened, it is separated from the limits of the two adjacent rotating plates 22, so that the parachute 17 is fully deployed to protect the manned aircraft;

[0089] Step 6: After the manned aircraft lands smoothly, the driving member 73 drives the extrusion frame 72 to reset and move, and all the limit members 70 are reinserted into the second storage shell 11, and then the sliding seat 12 is manually reset. After the sliding seat 12 is reset, all the clamping members 51 and the swing frame 15 are also swung and reset;

[0090] In the seventh step, after all the clamping members 51 and the swing frame 15 are reset, the parachute 17 is stored in the second storage shell 11 , and the two rotating plates 22 on the swing frame 15 fix the parachute 17 , and then the traction member 80 is fixed to all the clamping members 51 .

[0091] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
