Technical Field
[0001] The utility model relates to intelligent fire fighting equipment, in particular to an intelligent fire fighting escape device. Background Art
[0002] When a fire occurs, the stairwell will be "occupied" by thick smoke, and the elevator will stop running due to the fire. In order to deal with high-rise fires, most families will prepare escape tools. Currently, the most common ones on the market are slow-descent ropes, soft ladders, and escape bags. Although slow-descent ropes can also be used for emergency escape, there are some shortcomings. For example, only one person can be lowered at a time, and the rope needs to be retracted before descending. This is too slow for fire rescue, which is extremely urgent and cannot be delayed for a second. Although escape bags and soft ladders can achieve rapid escape for multiple people, they may not be used by some people with lower limb disabilities and people in wheelchairs, especially people with lower limb disabilities living alone. The reason is: the soft ladder requires the escapee to use both hands and feet to climb down quickly, and when using an escape bag, since most escape bags are installed at the window, it is difficult for people with lower limb disabilities to rely on their own abilities to enter the bag entrance.
[0003] To this end, we have designed an intelligent fire escape device for people with lower limb disabilities. If a fire occurs when they live alone, they can escape alone without relying on the help of others. Utility Model Content

DETAILED DESCRIPTION
[0025] The utility model is described in detail below in conjunction with the accompanying drawings.
[0026] like Figure 1-6 As shown, an intelligent fire escape device includes a lifting platform 1, a support platform 3 and an escape bag 5. A plastic protective cover 2 is arranged on the outside of the lifting platform 1 to protect the internal parts and improve the appearance. The lifting platform 1 includes a base 11, which can be fixed to the wall on one side of the bottom plate or the window sill by bolts. A horizontally arranged long axis 17 is arranged on the base 11, and worms 19 are arranged at both ends of the long axis 17. Two lead screws 13 are arranged on the corresponding base 11. The lead screws 13 are fixed by a shaft bracket 12. A worm wheel 20 is fixed at the lower end of the lead screw 13. The worm wheel 20 is matched with the corresponding worm 19 for transmission. A slider 14 sliding along the shaft bracket 12 is respectively arranged on the two lead screws 13. The slider 14 is threadedly connected to the lead screw 13. A short axis 15 is rotatably arranged on the opposite side of the two sliders 14. The two short axes jointly fix a horizontal cushion 16, and the horizontal cushion 16 rotates with the short axis.
[0027] The slider 14 can be driven up and down by rotating the lead screw 13, thereby driving the horizontal cushion 16 to move up and down, wherein the long shaft 17 is driven to rotate by the reduction motor 18, and the long shaft 17 and the reduction motor 18 are respectively provided with mutually meshing helical gears.
[0028] In addition, a missing gear 21 is fixed on one of the short shafts 15, and a spur rack 22 is arranged along the length direction of the shaft bracket 12 near the missing gear 21, and the middle and upper sections of the spur rack 22 are provided with teeth. When the missing gear 21 moves upward with the short shaft 15, the missing gear 21 and the spur rack 22 can mesh. After meshing, the missing gear 21 rotates and drives the horizontal cushion 16 to rotate a certain angle through the short shaft 15. The escapee using the present device can slide freely into the escape bag by using the inclined horizontal cushion 16.
[0029] like Figure 3 As shown, a retaining tooth 211 is provided on the missing gear 21. The retaining tooth 211 is the two outermost teeth of the missing gear 21. The radial length of the retaining tooth 211 is greater than that of other teeth. When the missing gear 21 rotates a certain angle, one of the retaining teeth 211 presses against the spur rack 22, limiting the rotation angle of the missing gear 21 in the clockwise or counterclockwise direction, thereby limiting the angle of the horizontal seat cushion 16. More specifically, when the horizontal seat cushion 16 is raised, one of the retaining teeth 211 limits its rotation angle to no more than 90 degrees. When the horizontal seat cushion 16 is not in contact with the teeth of the spur rack 22, the other retaining tooth 211 limits the horizontal seat cushion 16 to be roughly horizontal.
[0030] like Figure 4 As shown, the horizontal seat cushion 16 includes a seat cushion body and a rotatable swivel pad 4 arranged on the seat cushion. The swivel pad 4 is arranged at the upper center of the horizontal seat cushion 16. A receiving groove matching the size of the swivel pad 4 is provided on the upper side of the horizontal seat cushion 16. The swivel pad 4 can rotate horizontally in the accommodating groove. In order to increase friction, a rubber anti-slip pad (not shown in the figure) is provided on the upper side of the swivel pad 4.
[0031] After the escapee is transferred from the wheelchair to the horizontal cushion 16, he can rotate by holding the guardrails on both sides of the horizontal cushion 16 and turn his face toward the escape bag, which is more conducive to escape.
[0032] In addition, it also includes a driving device 6 for driving the rotating pad 4 to rotate. The driving device 6 is a motor, which is arranged at the bottom of the lifting platform 1, and the motor shaft is fixedly connected to the rotating pad 4. The rotating pad 4 can be automatically rotated by the motor. A start-stop switch 8 is arranged on one side of the protective cover 2, which can be used as one of the manual start-up methods of the device, and can control the manual start and stop of the reduction motor 18 and the driving device 6, or can be started by a remote controller. This is a conventional technology and will not be described in detail here.
[0033] In a preferred embodiment, the rotating pad 4 rotates only 180 degrees at a time.
[0034] In order to make the device more time-saving and labor-saving, an intelligent control module can also be configured. The intelligent control module includes a pressure sensor and a controller. The pressure sensor is arranged on the horizontal cushion 16, and is used to detect the position of the escaped person and transmit the data to the controller. The controller is arranged on the base 11 and is connected to the reduction motor 18 to control the operation of the reduction motor 18. In addition, the controller is also connected to the drive device 6.
[0035] When the escapee is transferred from the wheelchair to the horizontal cushion 16, the pressure sensor receives a steady pressure and transmits the acquired data to the controller. After receiving the signal, the controller starts the reduction motor 18 and the drive device 6 to automatically raise the horizontal cushion 16 and rotate the rotating cushion 4. The utility model can save the step of the escapee pressing the start switch by setting an intelligent control module, solve the disadvantage of accidentally touching the start switch in daily life, and save time and steps.
[0036] Specific reference Figure 6 The support platform 3 is arranged between the lifting platform 1 and the windowsill. The height of the support platform 3 is slightly higher than the lower edge of the window 7 and lower than the height of the horizontal cushion 16 after it is raised. The lower edge of the entrance of the escape bag 5 is arranged on the upper side of the support platform 3, and the rest of it extends out of the window.
[0037] Specifically, Figure 5 As shown, the upper edge of the support platform 3 away from the lifting platform 1 extends horizontally outward to form an extension portion 31, and the upper end surface of the extension portion 31 is convex arc-shaped. The extension portion 31 is provided to achieve a smooth transition to avoid falling instantly after entering the bag and not being able to react in time.
[0038] The utility model can help people with lower limb disabilities to escape from fire danger by using escape bags, and can effectively reduce casualties caused by lower limb disabled people due to mobility difficulties when encountering fire. The utility model has a simple and compact structure, is designed for special groups of people, and can provide a way for lower limb disabled people to save themselves in case of sudden fire.
[0039] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
