Description

Technical Field

[0001] The present invention relates to the technical field of engineering fire protection windows, and specifically to an escape device based on engineering fire protection. Background Art

[0002] Engineering fire protection windows are important safety facilities in buildings and are rescue channels designed for emergencies such as fires. Engineering fire protection windows play a crucial role in fire rescue and are one of the important measures to ensure the safety of personnel's lives and property.

[0003] Referring to Chinese Publication No. CN216076824U, this patent discloses an escape device based on building engineering fire protection, including a protective outer frame, and both the front and rear of the protective outer frame are open. A top box is fixedly installed above the protective outer frame, and a backup power supply is arranged inside the top box. Hinges are fixedly installed on both sides of the protective outer frame, and an outer frame window is hingedly installed on the protective outer frame through the hinges, and the number of outer frame windows is two. Entrance and exit openings are respectively formed through both sides of the front of the top box, and a partition is welded and installed inside the top box.

[0004] In case of a fire, due to the installation of traditional protective fences, it is difficult to escape from the fire scene, and the height of the floor is relatively large, making it difficult to directly escape from the window position. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an escape device based on engineering fire protection to solve the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An escape device based on engineering fire protection includes a fence, a grid window is fixedly connected to the outer wall of the fence, and a warning mechanism is fixedly connected to the outer wall of the fence.

[0007] The warning mechanism includes:

[0008] A threaded column, which is fixedly connected to the outer wall of the fence;

[0009] A bolt, which is threadedly connected to the threaded column. The bolt can be rotated, and then the fence and the grid window can fall off. The setting of the bolt facilitates disassembly, and thus can quickly escape in case of a fire, improving the survival probability. When the bolt is rotated and loosened, the warning device is activated to emit a warning sound, and then a warning is issued to keep the people downstairs away, avoiding secondary injuries to the people downstairs during the descent. Moreover, the warning sound can effectively remind the surrounding residents, improving the fire rescue speed and reducing casualties;

[0010] A mounting block, to which the bolt is threadedly connected.

[0011] Preferably, a warning device is fixedly connected to the outer wall of the fence, and a plate switch is movably connected to the outer wall of the warning device.

[0012] Preferably, the warning device is in movable contact with a bolt, and a plum blossom groove is formed on the outer wall of the bolt.

[0013] Preferably, a gas generator is fixedly connected to the outer wall of the fence, and an airbag is fixedly connected to the outer wall of the gas generator.

[0014] Preferably, the number of the gas generator and the airbag is two, and the airbags are both located inside the fence and the grille window.

[0015] Preferably, a buffer mechanism is fixedly connected to the outer wall of the grille window. The buffer mechanism includes a mounting plate, and the outer wall of the mounting plate is fixedly connected to the outer wall of the grille window.

[0016] Preferably, a spring is fixedly connected to the outer wall of the mounting plate, a limit hook is fixedly connected to the end of the spring, the limit hook is clamped on the outer wall of the grille window. The setting of the gravity block can increase the gravity on one side of the grille window, making one side of the grille window face the ground, avoiding skewing during the landing process, increasing the survival probability. When a person is in the fence, the spring will also play a buffering role when touching the ground, providing further buffering and improving the buffering effect.

[0017] Preferably, a gravity block is also fixedly connected to the end of the spring, a connecting rod is fixedly connected to the outer wall of the gravity block, a telescopic rod is fixedly connected to the outer wall of the connecting rod, a parachute is fixedly connected to the outer wall of the telescopic rod, a raised block is fixedly connected to the outer wall of the limit hook. When the airbag initially expands, it will squeeze against the limit hook. The friction between the airbag and the raised block will drive the limit hook to fall off from the grille window. After the limit hook falls off from the grille window, the spring elastically elongates, and then drives the connecting rod to move. When the fence is falling towards the ground, the parachute faces the ground, and the airflow blows onto the parachute. The parachute is bounced open by the airflow impact. The parachute can spread out more than ten times its area. After the parachute spreads out, it bulges around the fence to withstand the airflow impact, and then the parachute buffers the falling speed. By utilizing the effect of the parachute being impacted by the airflow and then generating buffering, the fence slowly descends to the ground, achieving the rescue effect on people. The airbag is in movable contact with the limit hook.

[0018] The present invention provides an escape device based on engineering fire protection. It has the following beneficial effects:

[0019] 1. The escape device based on engineering fire protection can rotate bolts by rotation, and then the fence and the grille window can fall. The bolts are convenient for disassembly, so that people can escape quickly in case of fire, improving the survival rate. When the bolts are rotated and loosened, the warning device starts to emit a warning sound and then gives a warning to keep people downstairs away, avoiding secondary injuries to people downstairs during landing. Moreover, the warning sound can effectively remind the surrounding residents, improving the fire rescue speed and reducing casualties.

[0020] 2. The escape device based on engineering fire protection starts the gas generator to inflate the airbag. After inflation, the airbag expands. When people escape, they are located between the fence and the grille window. At this time, the expansion pad of the airbag is between people and the fence and the grille window, avoiding the collision between people and the fence when landing, playing a buffering effect. Moreover, the airbag can buffer again when landing, further improving the survival rate.

[0021] 3. The escape device based on engineering fire protection: when the airbag starts to expand initially, it will squeeze against the limit hook. The friction between the airbag and the convex block will drive the limit hook to fall off from the grille window. After the limit hook falls off from the grille window, the spring elastically elongates and then drives the connecting rod to move. When the fence falls towards the ground, the parachute faces the ground. The airflow blows onto the parachute, and the parachute bounces open under the impact of the airflow. The parachute can unfold to an area more than ten times its original size. After unfolding, the parachute bulges around the fence to withstand the airflow impact, and then the parachute buffers the falling speed, taking advantage of the impact of the airflow on the parachute to produce a buffering effect, so that the fence slowly descends to the ground, playing a rescue effect on people.

[0022] 4. The escape device based on engineering fire protection: through the setting of the gravity block, the gravity on one side of the grille window can be increased, making one side of the grille window face the ground, avoiding skewing during the landing process, and improving the survival rate. People are located in the fence, and the spring will also play a buffering role when it touches the ground, further buffering and improving the buffering effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0035] Embodiment 1, please refer to Figures 1-4 , the present invention provides a technical solution: An escape device based on engineering fire protection, including a fence 1, a grid window 2 is fixedly connected to the outer wall of the fence 1, and a warning mechanism 3 is fixedly connected to the outer wall of the fence 1;

[0036] The warning mechanism 3 includes:

[0037] A threaded column 32, the threaded column 32 is fixedly connected to the outer wall of the fence 1;

[0038] A bolt 33, the bolt 33 is threadedly connected to the threaded column 32;

[0039] A mounting block 31, the bolt 33 is threadedly connected to the mounting block 31.

[0040] A warning device 35 is fixedly connected to the outer wall of the fence 1, and a plate - type switch 34 is movably connected to the outer wall of the warning device 35.

[0041] The warning device 35 is in movable contact with the bolt 33, and a plum blossom groove 36 is provided on the outer wall of the bolt 33.

[0042] A gas generator 6 is fixedly connected to the outer wall of the fence 1, and an airbag 5 is fixedly connected to the outer wall of the gas generator 6.

[0043] The number of the gas generator 6 and the airbag 5 is two, and the airbags 5 are both located inside the fence 1 and the grid window 2.

[0044] During use, the mounting block 31 is installed in the wall at the window position and fixed by means of expansion screws. Then, the threaded column 32 is placed at the position of the mounting block 31, and the bolt 33 fixes the threaded column 32 and the mounting block 31, thereby fixing the fence 1 and the grid window 2 at the window position.

[0045] Combined with the attached Figure 2 As shown, in case of a fire, the bolt 33 can be rotated by rotation, and then the fence 1 and the grid window 2 can fall down.

[0046] Combined with the attached Figure 1 As shown, during installation, the bolt 33 presses the plate switch 34. At this time, the warning device 35 is in a power-off state. Then, when the bolt 33 rotates and loosens, the bolt 33 no longer presses the plate switch 34. Then, the warning device 35 is powered on and starts. The warning device 35 starts to emit a warning sound and then gives a warning to keep the people downstairs away.

[0047] Combined with the attached Figure 4 As shown, the warning device 35 and the gas generator 6 are electrically connected. Then, when the warning device 35 starts, the gas generator 6 will be started. The gas generator 6 is a device similar to that for inflating and starting a car in case of an emergency. Then, the gas generator 6 starts to inflate the airbag 5. After the airbag 5 is inflated, it expands. When people escape, they are located in the fence 1 and the grid window 2. At this time, the expansion pad of the airbag 5 is between the people and the fence 1 and the grid window 2.

[0048] Embodiment 2. Please refer to Figures 1-9 , on the basis of Embodiment 1, the present invention provides a technical solution:

[0049] A buffer mechanism 4 is fixedly connected to the outer wall of the grid window 2. The buffer mechanism 4 includes a mounting plate 42, and the outer wall of the mounting plate 42 is fixedly connected to the outer wall of the grid window 2.

[0050] A spring 41 is fixedly connected to the outer wall of the mounting plate 42, and a limit hook 47 is fixedly connected to the end of the spring 41. The limit hook 47 is clamped on the outer wall of the grid window 2.

[0051] The end of the spring 41 is also fixedly connected with a gravity block 44. The outer wall of the gravity block 44 is fixedly connected with a connecting rod 45. The outer wall of the connecting rod 45 is fixedly connected with a telescopic rod 46. The outer wall of the telescopic rod 46 is fixedly connected with a parachute 43. The outer wall of the limit hook 47 is fixedly connected with a raised block 48. The airbag 5 is in movable contact with the limit hook 47.

[0052] Combined with the attached Figure 8 and 9 As shown, the airbag 5 is located at a position adjacent to the limit hook 47, and the limit hook 47 is a semi-circular hook on the grid window 2. When the airbag 5 starts to expand initially, it will squeeze against the limit hook 47. The friction between the airbag 5 and the raised block 48 will drive the limit hook 47 to fall off from the grid window 2. The spring 41 itself has elasticity. After the limit hook 47 falls off from the grid window 2, the spring 41 elastically elongates, and then drives the connecting rod 45 to move. When the fence 1 is falling towards the ground, the parachute 43 faces the ground. The airflow blows onto the parachute 43, and the parachute 43 bounces open under the impact of the airflow. The parachute 43 can unfold to an area more than ten times its original size. Then, when the parachute 43 unfolds, it will also pull the telescopic rod 46 to elongate. After the parachute 43 unfolds, it bulges around the fence 1 to bear the impact of the airflow, and then the parachute 43 buffers the falling speed.

[0053] Combined with the attached Figure 8 As shown, the setting of the gravity block 44 can increase the gravity on one side of the grid window 2, making one side of the grid window 2 face the ground. At this time, a person is inside the fence 1, and then the spring 41 will also play a buffering role when it touches the ground.

[0054] Embodiment 3, please refer to Figures 1-9 This invention provides another technical solution:

[0055] An escape device based on engineering fire protection, including a fence 1. The outer wall of the fence 1 is fixedly connected with a grid window 2. The outer wall of the fence 1 is fixedly connected with a warning mechanism 3.

[0056] The warning mechanism 3 includes:

[0057] A threaded column 32, which is fixedly connected to the outer wall of the fence 1;

[0058] A bolt 33, which is threadedly connected to the threaded column 32;

[0059] A mounting block 31, to which the bolt 33 is threadedly connected.

[0060] The outer wall of the fence 1 is fixedly connected with a warning device 35. The outer wall of the warning device 35 is movably connected with a plate switch 34.

[0061] The warning device 35 is in movable contact with the bolt 33, and a plum blossom groove 36 is formed on the outer wall of the bolt 33.

[0062] The outer wall of the fence 1 is fixedly connected with a gas generator 6, and the outer wall of the gas generator 6 is fixedly connected with an airbag 5.

[0063] There are two gas generators 6 and airbags 5, and the airbags 5 are both located inside the fence 1 and the grid window 2.

[0064] The outer wall of the grid window 2 is fixedly connected with a buffer mechanism 4. The buffer mechanism 4 includes a mounting plate 42, and the outer wall of the mounting plate 42 is fixedly connected with the outer wall of the grid window 2.

[0065] The outer wall of the mounting plate 42 is fixedly connected with a spring 41. The end of the spring 41 is fixedly connected with a limit hook 47, and the limit hook 47 is clamped on the outer wall of the grid window 2.

[0066] The end of the spring 41 is also fixedly connected with a gravity block 44. The outer wall of the gravity block 44 is fixedly connected with a connecting rod 45. The outer wall of the connecting rod 45 is fixedly connected with a telescopic rod 46. The outer wall of the telescopic rod 46 is fixedly connected with a parachute 43. The outer wall of the limit hook 47 is fixedly connected with a raised block 48, and the airbag 5 is in movable contact with the limit hook 47.

[0067] During use, the mounting block 31 is installed in the wall at the window position and fixed by means of expansion screws. Then the threaded column 32 is placed at the position of the mounting block 31, and the bolt 33 fixes the threaded column 32 and the mounting block 31, thereby fixing the fence 1 and the grid window 2 at the window position;

[0068] An electric screwdriver and other devices can be set on the fence 1 in advance, and then tools such as a screwdriver or a wrench are installed. The screwdriver is adapted to the plum blossom groove 36 and then drives the bolt 33 to rotate. The wrench is adapted to the plum blossom groove 36 and can drive the bolt 33 to rotate, and then quickly escape;

[0069] Combined with the attached Figure 2 As shown, in case of a fire, the bolt 33 can be rotated by turning, and then the fence 1 and the grid window 2 can fall down;

[0070] Combined with the attached Figure 1 As shown, during installation, the bolt 33 presses the plate switch 34. At this time, the warning device 35 is in a power-off state. Then when the bolt 33 rotates and loosens, at this time the bolt 33 no longer presses the plate switch 34, and then the warning device 35 is powered on and starts. The warning device 35 starts to emit a warning sound and then gives a warning to keep the people downstairs away.

[0071] Combined with the attached Figure 4As shown, the warning device 35 and the gas generator 6 are electrically connected. Then, when the warning device 35 is activated, the gas generator 6 will be activated. The gas generator 6 is a device similar to that used for inflating and starting in case of an emergency in a vehicle. Then, when the gas generator 6 is activated, it inflates the airbag 5. After the airbag 5 is inflated, it expands. When people are escaping, they are located in the fence 1 and the grille window 2. At this time, the expansion pad of the airbag 5 is between the people and the fence 1 and the grille window 2.

[0072] Combined with the attached Figure 8 and 9 As shown, the airbag 5 is located near the limit hook 47. The limit hook 47 is a semi-circular hook on the grille window 2. When the airbag 5 starts to expand initially, it will squeeze against the limit hook 47. The friction between the airbag 5 and the raised block 48 will cause the limit hook 47 to fall off the grille window 2. The spring 41 itself has elasticity. After the limit hook 47 falls off the grille window 2, the spring 41 elastically elongates, and then drives the connecting rod 45 to move. When the fence 1 falls towards the ground, the parachute 43 faces the ground. The airflow blows onto the parachute 43, and the parachute 43 bounces open due to the impact of the airflow. The parachute 43 can unfold to an area more than ten times its original size. Then, when the parachute 43 unfolds, it also pulls the telescopic rod 46 to elongate. After the parachute 43 unfolds, it bulges around the fence 1 to withstand the impact of the airflow, and then the parachute 43 buffers the falling speed.

[0073] Combined with the attached Figure 8 As shown, the setting of the gravity block 44 can increase the gravity on one side of the grille window 2, making one side of the grille window 2 face the ground. At this time, people are located in the fence 1. Then, the spring 41 will also play a buffering role when it touches the ground.

[0074] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
