[0052] Figure 1 Schematic diagram of the working state of the safety device for high-rise building escape according to an embodiment of the present invention; Figure 2 is Figure 1 Cross-sectional view of the safety device for high-rise building escape shown in Figure 3 is Figure 1 Cross-sectional view of the storage state of the safety device for high-rise building escape shown in Figure 4 is Figure 2 Enlarged view of part A of the safety device for high-rise building escape shown in Figure 5 is Figure 2 Enlarged view of part B of the safety device for high-rise building escape shown in Figure 6 is Figure 2 Enlarged view of part C of the safety device for high-rise building escape shown in

[0053] As Figures 1 - 6 shown, the safety device for high-rise building escape includes a support ring 1, a mounting ring 7, a grid frame 23, a plurality of first support rods 19, a support plate 36, a support frame 11, a protective net 12, a motor 30, a first rotating rod 13, a rotating blade 14, an airbag 2, an air storage tank 21, rollers 45 and a plurality of second support rods 3.

[0054] The support ring 1 is arranged as a hollow cylinder; the installation ring 7 is connected to the first end face of the support ring 1 in the length extension direction in an openable and closable manner; the grid frame 23 is fixedly connected to the inner wall of the support ring 1 in the circumferential direction and bulges away from the installation ring 7; the first ends of a plurality of first support rods 19 are fixedly connected to the installation ring 7 at circumferential intervals, and the second ends extend away from the grid frame 23; the support plate 36 is fixedly connected to the second end of each first support rod 19; the support frame 11 is fixedly connected to the installation ring 7 in the circumferential direction and covers the support plate 36; the protective net 12 is laid on the surface of the support frame 11 facing the grid frame 23; the motor 30 is connected to the side of the support plate 36 facing the protective net 12; the first end of the first rotating rod 13 is drivingly connected to the output shaft of the motor 30, and the second end penetrates through the protective net 12 and the support frame 11; the rotating blade 14 is fixedly connected to the second end of the first rotating rod 13; the airbag 2 is connected to the side of the grid frame 23 facing away from the installation ring 7; the gas storage tank 21 is fixed to the side of the grid frame 23 facing the installation ring 7, the air injection pipe 41 connects the gas storage tank 21 and the airbag 2, and a valve is arranged on the air injection pipe 41; the roller 45 is connected to the side of the airbag 2 facing away from the grid frame 23; a plurality of second support rods 3 are rotatably connected to the outer wall of the support ring 1 in the circumferential direction and are located on the expansion path of the airbag 2.

[0055] When there is no high-rise building fire, the safety device for high-rise building escape is placed at positions such as balconies. The second support rod 3 is vertically arranged, the airbag 2 is not inflated, the roller 45 at the bottom of the airbag is separated from the ground, and the second support rod 3 supports the safety device.

[0056] When a high-rise fire occurs, personnel will lift up the installation ring 7 and the structure connected thereto, enter the interior of the grid frame 23, close the installation ring 7 to connect the installation ring 7 with the support ring 1, and then open the valve on the injection pipe 41 to quickly fill the gas inside the gas storage tank 21, such as carbon dioxide, into the airbag 2, so that the airbag 2 quickly expands and stretches, and the vertically arranged second support rod 3 located on the expansion path of the airbag 2 is bounced to a horizontal state, and the airbag 2 abuts against the bottom end of the second support rod 3. Moreover, a fixed wall or fixed plate structure is pre-set at the balcony or other location where the safety device is placed, and the height is less than the height of the rotating blade 14, and is arranged close to the second support rod 3. Therefore, when the second support rod 3 is deployed due to the springing of the airbag 2, the end of the second support rod 3 away from the support ring 1 hits the fixed wall or fixed plate structure on the side, so that the safety device is subjected to a reverse thrust. At the same time, during the deployment of the second support rod 3, the roller 45 at the bottom of the airbag 2 contacts the ground, so that the safety device subjected to the reverse thrust slides along the balcony or other location to the outside of the high-rise building under the drive of the roller 45 until it is separated from the high-rise building. At the same time, the motor 30 is started, and the output shaft of the motor 30 rotates to drive the first rotating rod 13 and the rotating blade 14 directly or indirectly connected thereto to rotate, thereby generating wind flow, generating an upward buoyancy on the safety device, reducing the pressure of the roller 45 at the bottom of the safety device on the balcony or other location, so that the safety device can move away from the wall more quickly and separate from the high-rise building under the reverse thrust of the second support rod 3 and the drive of the roller 45. After the safety device is completely separated from the high-rise building, during the process of falling from the high altitude, under the action of the wind flow generated by the rotation of the rotating blades 14, the safety device is subjected to a vertical reverse thrust in the high altitude, which slows down the landing speed of the safety device and reduces the vibration and impact of the personnel inside the safety device when landing. The generated wind flow will also blow away the smoke generated by the high-rise fire to reduce the impact on the personnel inside the safety device, and drive the wind flow inside the safety device to reduce the impact of high temperature on the personnel inside the safety device. At the same time, during the falling process, the protective net 12 and the support frame 11 block and intercept the falling objects generated by the high-rise fire, providing protection for the personnel inside the safety device.

[0057] By adopting the safety device for high-rise building escape of the present invention, when a fire occurs in a high-rise building, personnel can enter the safety device, inflate the airbag 2, make the second support rod 3 open horizontally and push the nearby wall panel backward, make the roller 45 slide on the ground, and at the same time drive the rotating blade 14 to rotate with the help of the motor 30 to generate upward buoyancy, under the joint action, the safety device is separated from the high-rise building, and in the process of falling from a high altitude, the buoyancy generated by the rotation of the rotating blade 14 is used to slow down the landing speed of the safety device, blow away the smoke, and reduce the internal temperature of the safety device. At the same time, the protective net 12 and the support frame 11 block and intercept the falling objects from the high altitude, so as to ensure that the personnel inside the safety device can safely fall from the high-rise building to the ground.

[0058] In this embodiment, the support ring 1 is of an annular structure and is horizontally arranged. An installation ring 7 is provided at the top of the support ring 1. The installation ring 7 is also of an annular structure and is horizontally arranged, and is detachably connected to the support ring 1. A plurality of first support rods 19 are circumferentially and fixedly arranged at intervals at the top of the installation ring 7. Each first support rod 19 is inclined upward at the same angle. The top of each first support rod 19 is fixed to the support plate 36. The support plate 36 is of a circular plate structure and is erected at the center above the installation ring 7. A support frame 11 is also fixed to the top of the installation ring 7. As Figure 1 shown, the support frame 11 is formed by connecting a plurality of arc-shaped rods. The bending arcs of the plurality of arc-shaped rods are the same, and they all bulge upward. They are arranged at equal intervals along the circumference of the installation ring 7 and are fixedly connected on the axis of the installation ring 7. A protective net 12 is laid on the inner side of the support frame 11. The protective net 12 is a grid net structure made of magnesium-aluminum alloy wires and has the same arc-shaped arch structure as the support frame 11. The motor 30 is arranged at the center of the top surface of the support plate 36. Storage batteries 16 are installed on both sides and are connected to the indoor circuit through power lines for charging and standby use. It is electrically connected to the motor 30 through wires to provide power for the motor 30. As Figure 2 shown, the lower end of the first rotating rod 13 is fixedly connected to the output shaft of the motor 30, and the upper end passes through the protective net 12 and the support frame 11 and extends to the outside. The upper end of the first rotating rod 13 is fixedly provided with a rotating blade 14. The rotating blade 14 is of a strip-shaped structure and is horizontally arranged. Its rotating diameter is larger than the diameter of the support ring 1. The rotating blade 14 and the first rotating rod 13 are driven by the motor 30 to rotate. As Figure 5 shown, a first installation hole 39 is opened in the middle of the top of the support frame 11. A first bearing 40 is installed inside the first installation hole 39. The first rotating rod 13 passes through the first bearing 40 to realize the rotatable connection with the support frame 11 and maintain the stability of the rotation of the first rotating rod 13. A grid frame 23 is fixed to the bottom end of the inner surface of the support ring 1. The grid frame 23 is of an arc-shaped structure and bulges away from the protective net 12, which can support the internal personnel of the safety device. The grid frame 23 and the protective net 12 enclose the internal space of the safety device. As Figure 2 and Figure 3As shown in the figure, a plurality of gas storage tanks 21 are fixed to the upper end of the grid frame 23, which store high-pressure carbon dioxide gas inside. The lower end of the grid frame 23 is connected to an airbag 2. The airbag 2 is made of flame-retardant cloth material and is an arc-shaped concave structure. The surface of the airbag 2 has good flame-retardant performance to avoid burning during the landing process due to the influence of high-rise building fires. The air outlet of each gas storage tank 21 is connected to a spray pipe 41. The lower end of the spray pipe 41 communicates with the inside of the airbag 2. A valve is installed on the spray pipe 41. When the safety device needs to be used, the valve is opened to quickly inflate the inside of the airbag 2. A plurality of rollers 45 are connected to the center position at the bottom end of the airbag 2. A plurality of second support rods 3 are circumferentially and spaced apart on the outer wall of the bottom end of the support ring 1. The second support rods 3 are long rectangular rod structures and are rotatably connected to the support ring 1. As Figure 3 shown, when there is no fire and the high-rise building escape safety device is in the storage state, the second support rods 3 are vertically arranged to play a supporting role. The airbag 2 is not inflated, and the rollers 45 are separated from the ground, and the safety device as a whole cannot move. As Figure 2 shown, when a fire occurs, the airbag 2 is inflated and expands into an arc-shaped structure. During the expansion process, the second support rods 3 located on the expansion path are pushed, causing the second support rods 3 to rotate relative to the support ring 1 and finally being in a horizontal state. Moreover, the rollers 45 at the bottom end of the airbag 2 come into contact with the ground and slide. In this embodiment, structures such as the support ring 1, the installation ring 7, the grid frame 23, the first support rod 19, the support plate 36, the first rotating rod 13, the rotating blade 14, and the protective net 12 are all made of magnesium alloy material, which is light in weight and high in hardness, can reduce the overall weight of the safety device, and is conducive to the safe landing and movement of the safety device from high altitude.

[0059] Figure 9 For Figure 2 the top view of the connection relationship between the support frame and the rotating plate of the high-rise building escape safety device shown; Figure 10 For Figure 2 the top view of the connection relationship between the first rotating rod and the second rotating rod of the high-rise building escape safety device shown. As Figures 2 - 4 、 Figure 9 and Figure 10 shown, optionally, the high-rise building escape safety device further includes a rotating plate 17, a rotating column 26, a support frame 15, a first helical gear 31, a second rotating rod 9, and a helical blade 10.

[0060] The rotating plate 17 is rotatably connected to one side of the support plate 36 facing the protective net 12; the motor 30 is fixedly connected to one side of the rotating plate 17 facing the protective net 12; the rotating column 26 penetrates through the support plate 36 and is fixedly connected to the rotating plate 17; the support frame 15 is fixedly connected to one side of the rotating plate 17 facing away from the support plate 36; the first helical gear 31 is sleeved on the first rotating rod 13 and is fixedly connected to the first rotating rod 13; the second helical gear 32 is sleeved on the second rotating rod 9 and is fixedly connected to the second rotating rod 9 and meshes with the first helical gear 31, the second rotating rod 9 penetrates through the support frame 15 and is rotatably connected to the support frame 15; the spiral blade 10 is fixedly connected to the circumference of the second rotating rod 9 penetrating through the support frame 15.

[0061] When there is no fire, the spiral blade 10 is placed facing the wall. When a fire occurs, the motor 30 is started. While the motor 30 drives the first rotating rod 13 to rotate, it drives the first helical gear 31 to rotate, and further drives the second helical gear 32 meshing with the first helical gear 31 to rotate. The rotation of the second helical gear 32 then drives the second rotating rod 9 and the spiral blade 10 directly or indirectly fixedly connected thereto to rotate. During the rotation of the spiral blade 10, it blows air towards the wall structure on the side of the safety device. Therefore, the safety device receives a reaction force in the same direction as the thrust generated by the second support rod 3. That is, when a fire occurs in a high-rise building, the top of the safety device receives the buoyancy generated by the rotation of the rotating blade 14. Its bottom is slidably arranged on the ground through the roller 45, and its side is jointly affected by the reaction force generated by the rotation of the spiral blade 10 and the reaction force generated by the deployment of the second support rod 3. Therefore, after people enter the safety device, the safety device can quickly leave the high-rise building and stay away from the high-rise building fire, improving safety. In addition, after the safety device leaves the high-rise building fire area and descends from a high altitude, during the descent, people inside the safety device can drive the rotating plate 17 connected thereto to rotate synchronously by rotating the rotating column 26, and then drive the support frame 15, the motor 30, the first rotating rod 13, the second rotating rod 9 and the spiral blade 10 directly or indirectly connected to the rotating plate 17 to rotate synchronously by a certain angle, so that the spiral blade 10 blows air in different directions, causing the safety device to receive reaction forces in different horizontal directions, driving the safety device to move in the reverse direction, enabling the movement direction of the safety device to be adjusted and controlled in different directions, and driving the generation of air flow inside the safety device, reducing the high temperature inside the safety device affected by the high-rise building fire, improving the comfort of the people inside the safety device, enabling the safety device to move in different directions away from the high-rise building fire during the slow descent process, and avoiding the safety device hitting other external objects, which is conducive to the safe landing of the safety device with people on the ground.

[0062] Such as Figures 2 - 4 、 Figure 9 and Figure 10As shown, in this embodiment, a rotating plate 17 is rotatably mounted on the top of the support plate 36. The rotating plate 17 is a circular plate structure, and its diameter is larger than the diameter of the support plate 36. A rotating column 26 is fixed in the middle of the bottom end of the rotating plate 17. The rotating column 26 is vertically arranged, and the lower end passes through the support plate 36. A motor 30 is fixed at the top center of the rotating plate 17. A first rotating rod 13 is installed on the top of the motor 30. The first rotating rod 13 is vertically arranged, and the bottom end thereof is sleeved with a first bevel gear 31. The second rotating rod 9 is horizontally arranged, and the left end of the second rotating rod 9 is sleeved with a second bevel gear 32, which is meshed with the first bevel gear 31. The top edge of the rotating plate 17 is fixed with a support frame 15. The support frame 15 is a rectangular frame structure. The right side wall thereof is penetrated with a second mounting hole 35. The second mounting hole 35 is internally installed with a second bearing 34. The second rotating rod 9 passes through the second bearing 34 to achieve a rotatable connection with the support frame 15. The spiral blade 10 is fixed to the right end circumference of the second rotating rod 9 and is vertically arranged. It fans the air from the inside of the safety device to the outside and generates a reverse thrust, driving the safety device to move in the opposite direction. It is arranged close to the protective net 12. The mesh of the protective net 12 is relatively large and does not hinder the fanning of the spiral blade 10 and the circulation of the wind. In order to prevent the second rotating rod 9 from generating excessive horizontal shaking during the rotation process, such as Figure 4 As shown, first limit plates 33 are fixed to the positions of the second rotating rod 9 on both sides of the second mounting hole 35. The outer diameter of the first limit plates 33 is larger than the inner diameter of the second mounting hole 35 to prevent the second rotating rod 9 from moving a large distance to the left and right, thereby affecting the normal meshing of the first bevel gear 31 and the second bevel gear 32. Figure 2 As shown, the top of the support frame 15 abuts against the inside of the protective net 12 to prevent up and down shaking, further reinforce and stabilize the second rotating rod 9, prevent the second rotating rod 9 and the spiral leaf 10 from shaking up and down during the rotation process, and reinforce and support the top of the protective net 12 and the support frame 11 to prevent the top of the support frame 11 from being hit and damaged by falling objects, and further prevent falling objects from hitting the top of the safety device and injuring the internal personnel during a high-rise fire. In addition, in this embodiment, the diameter of the first bevel gear 31 is larger than the diameter of the second bevel gear 32, so when the two are meshed and connected, the rotation speed of the second rotating rod 9 and the spiral leaf 10 is greater than the rotation speed of the first rotating rod 13 and the rotating leaf 14, which is conducive to increasing the horizontal driving force of the spiral leaf 10 on the safety device.

[0063] Optionally, the outer wall of the rotating column 26 is provided with an external thread; the high-rise escape safety device further comprises a fastening plate 38 , which is sleeved on the rotating column 26 on the side of the support plate 36 facing away from the rotating plate 17 and is threadedly connected to the rotating column 26 . With this arrangement, when the direction of the spiral blade 10 needs to be adjusted, the top end of the fastening plate 38 is clearance-matched with the bottom end of the supporting plate 36. Then, when the rotating plate 17, the supporting frame 15, the second rotating rod 9 and the spiral blade 10 are driven to rotate by rotating the rotating column 26, the fastening plate 38 threadedly connected to the rotating column 26 rotates synchronously therewith; when the spiral blade 10 is adjusted to the appropriate direction, the rotating column 26 is held and the fastening plate 38 is rotated so that the fastening plate 38 moves upward in a spiral relative to the rotating column 26 until it is tightly abutted against the lower end surface of the supporting plate 36, so that the rotating column 26 cannot rotate, thereby making the rotating plate 17 and the supporting plate 36 fit tightly to prevent shaking, and then the motor 30 and the first rotating rod 13 fixed to the rotating plate 17 are stably arranged to reduce the shaking of the first rotating rod 13.

[0064] like Figure 4 As shown, in this embodiment, a fastening plate 38 is provided on the lower side of the support plate 36. The fastening plate 38 is a circular plate structure and is arranged horizontally. A first connecting hole 29 is provided through the center of the support plate 36, and a second connecting hole 27 is provided through the corresponding position of the fastening plate 38, and an internal thread is provided, and a rotating column 26 is sleeved and threadedly connected with the rotating column 26.
