DETAILED DESCRIPTION

[0026] The following is an explanation of the implementation of the present invention by specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The technical scheme in the embodiment of the present invention is clearly and completely described through the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all embodiments.

[0027] Referring to Figure (1), the household high-rise fire escape backpack device includes five parts: a five-point safety belt, a slow-descent device, a handbrake safety device, an intelligent distance-measuring deceleration device, and a backpack shell. When a fire occurs, a person puts on the backpack through the five-point safety belt and hangs the safety hook at the top of the entire device on a hanger outside the window or a fixed position to start escaping. The first end of the five-point safety belt is connected to the backpack shell. When descending, the slow-descent device located at the bottom of the backpack shell works to reduce the speed to 1.5m / s. The person operates the handbrake safety device located just above the backpack shell and squeezes the brake handle at the lower right end of the backpack shell. The brake line is tightened to start braking, and the movement continues after releasing. When there is still 5m from the ground, the intelligent distance-measuring deceleration device located in the middle and upper part of the backpack shell works to reduce the speed to within 0.5m / s. The safety rope starts from the top safety hook and is connected to the intelligent distance-measuring deceleration device and the slow-descent device in sequence. Various devices work together to achieve safe landing from a high-rise building. After landing, the five-point safety belt is untied to achieve escape.

[0028] The five-point safety belt (52) comprises a first backpack buckle (31), a second backpack buckle (32), a third backpack buckle (33), a fourth backpack buckle (34), a fifth backpack buckle (35), and a sixth backpack buckle (36). The first ends of the first backpack buckle (31) and the second backpack buckle (32) are located at the upper right and upper left ends of the backpack shell (1). The first ends of the third backpack buckle (33) and the fourth backpack buckle (34) are located at the left and right ends of the middle of the backpack shell (1). The first ends of the fifth backpack buckle (35) and the sixth backpack buckle (36) are located at the lower right and lower left ends of the backpack shell (1). The ends of the six backpack buckles are respectively connected to the first shoulder strap (37), the second shoulder strap (38), the third shoulder strap (39), the fourth shoulder strap (40), the fifth shoulder strap (41), and the sixth shoulder strap (42). The other ends of the six shoulder straps except the third shoulder strap (39) are connected to the Then, the first buckle (43), the second buckle (44), the fourth buckle (45), the fifth buckle (46), and the sixth buckle (47) are connected. The end of the third shoulder strap (39) is connected to the central buckle (48). When wearing the shoulder strap, the third shoulder strap (39) and the fourth shoulder strap (40) are first passed around the left and right waists respectively, and the fourth buckle (45) is inserted into the central buckle (48). Then, the first shoulder strap (37) and the second shoulder strap (38) are passed around the left and right shoulders from the back respectively, and the first buckle (43) and the second buckle (44) are inserted into the central buckle (48). Finally, the fifth shoulder strap (41) and the sixth shoulder strap (42) are passed around the crotch respectively, and the fifth buckle (46) and the sixth buckle (47) are inserted into the central buckle (48) to fix and protect the person. After the person lands, the central buckle (48) is pressed to unlock the five buckles and escape.

[0029] The descent control device (49) comprises a safety hook (53) located at the top of the entire device, a descent control housing (2) located outside the device and functioning to protect and support the internal mechanism, and a drum gear (3) located inside the descent control housing (2). A safety rope (54) is connected to the bottom of the safety hook (53) until it is connected to and wound around the outside of the drum gear (3) at the bottom. The drum gear (3) has a circle of gears inside. When escaping, the safety hook (53) must first be hung on a hanger outside the window or a fixed position. During the descent control process, the person descends and drives the drum gear (3) to rotate, which drives the pendulum gear (5) meshing with the internal gear of the drum gear (3) to start rotating. The pendulum gear (5) drives the shaft gear (6) meshing with it to rotate. When the shaft gear (6) rotates, the escape wheel (10) coaxial with it also rotates. The shaft gear (6) and the escape wheel (10) are coaxial and are fixedly connected to the shaft via a flat key. The pendulum gear (5) is fixedly connected to the shaft via a flat key. The inlet pin (8) and the outlet pin (9) located at the front end of the pendulum (7) can only swing left and right under the restriction of the weight block (4). At the same time, the inlet pin (8) and the outlet pin (9) consume the kinetic energy of the system by colliding with the escape wheel (10), and then control the rotation speed of the drum gear (3) and the rope release speed through the engagement of the shaft gear (6) and the pendulum gear (5), so as to realize the slow and uniform descent of the person. The pendulum (7) and the pendulum gear (5) are coaxial, and the pendulum (7) and the weight block (4) are connected by pins. The specific process is as follows: initially, the pendulum (7) is located at the left extreme position, at which time the escape wheel (10) and the inlet pin (8) are in contact at the tangent point of the tooth surface between the pendulum (7) and the escape wheel (10). When the drum gear (3) starts to rotate, torque is input, and the pendulum gear (5) meshing with the internal gear of the drum gear (3) starts to rotate. The torque is transmitted to the escape wheel (10) coaxial with the shaft gear (6) through the meshing of the pendulum gear (5) and the shaft gear (6). The escape wheel (10) then transmits the torque to the inlet pin (8). At the same time, the pendulum (7) accelerates clockwise under the action of the weight block (4) until the pendulum (7) and the escape wheel (10) are in contact. After the top of its gear teeth is disengaged from the meshing and meshing with the escape wheel (10), the pendulum (7) rotates freely at a uniform speed, and the escape wheel (10) rotates at an accelerated speed under the action of the input torque. The two collide with each other, consume energy, and the speed decreases. The remaining kinetic energy of the pendulum (7) forces the escape wheel (10) to rotate counterclockwise, so that the pendulum (7) stops when it is at the right limit position. At this time, the pin (9) contacts the tangent point of the tooth surface of the escape wheel (10). The escape wheel (10) forces the pendulum (7) to rotate counterclockwise at an accelerated speed under the action of the input torque, and completely disengages at the top of the gear teeth. After rotating a corresponding angle, the pin is ejected, and the above process is repeated to achieve the slow descent process.

[0030] The handbrake safety device (51) comprises a brake handle (24), the brake handle (24) is connected to the backpack shell (1) through a shaft, and the surface of the connection between the shaft and the backpack shell (1) is provided with a thread, and the two ends of the shaft at the connection are respectively fixedly connected to the backpack shell (1) through the cooperation of nuts and threads, and the brake handle (24) is located at the lower right end of the backpack shell (1). When braking, the brake handle (24) is squeezed, and the brake line (27) is tightened to close the ring buckle (25) and the push plate (26), driving the push rod (28) to push the wire hook (29) upward, and the other end of the wire hook (29) moves downward to the eight-shaped ring (30), and the safety rope (54) is wrapped around the eight-shaped ring (30). The wire hook (29) and the eight-shaped ring (30) cooperate to clamp the safety rope (54) to stop the movement of the safety rope to achieve braking. The propulsion sheet (26) and the wire-gripping hook (29) are fixed to two ends of the push rod (28) via pins, the propulsion sheet (26) and the figure-eight ring (30) are connected via pins, and the push rod (28) and the wire-gripping hook (29) are fixedly connected via pins.

[0031] The intelligent distance measuring and deceleration device (50) comprises a laser distance measuring sensor (11) located at the bottom of the backpack shell (1). When the laser distance measuring sensor (11) detects that there is still 5 m from the ground, an electrical signal is sent to a single chip microcomputer (12) fixed on a side panel at the left end inside the backpack shell (1) through a signal line (55). The single chip microcomputer (12) controls an electric push rod (13) located directly above the safety clamp shell (15) to pull upward a thin rod (14) located inside the safety clamp shell (15) below it. The electric push rod (13) is connected to the thin rod (14). The safety clamp inclined wedge synchronization frame (22) located directly below the thin rod (14) moves upward along with the thin rod (14), and at the same time pulls the left clamping block (20) and the right clamping block (21) matched therewith to slide upward, so that the two clamping blocks move along the left slide groove (18) fixed by the left fixed inclined wedge (19) and the right fixed inclined wedge (19) respectively. 16), the right slide groove (17) slides upward, the left clamping block (20) is connected to the left slide groove (16), the left slide groove (16) is fixedly connected to the left fixed wedge (18) by bolts, the right clamping block (21) is connected to the right slide groove (17), the right slide groove (17) is fixedly connected to the right fixed wedge (19) by bolts, the left fixed wedge (18) and the right fixed wedge (19) are fixed in the safety clamp bushing (23) by bolts, and the safety clamp wedge synchronization frame (22) is fixedly connected to the left clamping block (20) and the right clamping block (21) by bolts, so that when the left clamping block (20) and the right clamping block (21) slide upward along the slide groove, the two clamping blocks respectively gather toward the middle along the left through groove (56) and the right through groove (57) located inside the safety clamp wedge synchronization frame (22), clamping the safety rope (54) located between the two clamping blocks, achieving deceleration, and allowing people to land safely. The thin rod (14) is tightly connected to the safety gear wedge synchronization frame (22), and the safety gear bushing (23) is fixedly connected to the safety gear housing (15) by bolts.

[0032] The utility model can store 50 meters of safety rope (54), and can be used to escape from high buildings of different heights. Through the escapement mechanism in the descending device (49), the utility model is applicable to the backpack structure and avoids the situation that the friction descending device commonly used in the market fails when it encounters water or oil, thereby ensuring the safety of the product. At the same time, the backpack is equipped with a 24V, 12500 mAh battery for the electric push rod, and the battery is fully charged to enable the electric push rod (limit load 2000N) to work continuously for 5 hours under a push (pull) force of 1000N, and the battery can be stored for one year.

[0033] In the utility model, a slow-descent device and an intelligent distance-measuring deceleration device are installed inside the backpack shell (1), and the two are connected together by a safety rope. The outside is connected to a five-point safety belt, a handbrake safety device and a safety hook, thereby ensuring that the relative positions of the various devices are fixed and ensuring the power transmission during the operation and descent process of the household high-rise fire escape backpack device.
