Description

TECHNICAL FIELD

[0001] The utility model relates to fire fighting equipment technical field, especially a glass curtain wall broken window fire fighting device. BACKGROUND

[0002] With the acceleration of urbanization, high-rise buildings are increasingly popular in modern cities. However, high-rise building fires have the characteristics of fast fire spread, evacuation difficulty, limited rescue, etc., which seriously threaten the safety of people's life and property.

[0003] At present, the fire safety of high-rise buildings in China's "Building Design Fire Protection Code" has formulated relevant requirements: residential buildings with a building height of more than 100 meters must be equipped with automatic fire extinguishing system and automatic fire alarm system; residential buildings with a building height of 54 to 100 meters are required to install fire alarm system in public areas, and it is recommended to install fire detector in the suite; high-rise residential buildings with a building height of less than 54 meters are recommended to install fire alarm system in public areas, and must be installed if it needs to link control fire facilities. In addition, all public areas of high-rise residential buildings should be equipped with fire alarm device with voice function or emergency broadcasting system.

[0004] However, the existing specification has obvious shortcomings: for high-rise buildings with a building height of 25 to 100 meters, especially residential buildings, there is no mandatory requirement to install automatic fire extinguishing system. This regulatory gap leads to the fact that such buildings are difficult to be effectively controlled when a fire occurs, and it is easy to cause serious casualties and property losses. Traditional fire rescue equipment such as fire truck ladder and aerial work platform is often subject to multiple factors when dealing with such high-rise fires: first, the working height of the equipment itself is limited; second, the congestion of urban roads affects the arrival of rescue vehicles at the scene; third, the surrounding environment of the building limits the operation space. These factors together make it difficult for traditional fire rescue methods to meet the growing demand for high-rise building fire protection.

[0005] Especially in the actual rescue process, due to the fact that fire vehicles cannot arrive at the fire scene in time, or because of the obstruction of parking, greenery and other facilities around the building, the operation cannot be effectively carried out, which greatly delays the best opportunity for fire fighting. These problems have been fully confirmed in major fire accidents in many cities in China, highlighting the urgency of developing new high-rise building fire rescue equipment. INVENTION CONTENTS

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] like Figures 1 to 4 As shown in the figure, the glass curtain wall window breaking fire-fighting device described in this embodiment is used for high-rise building fire rescue. It aims to provide a device that can overcome height limitations and safely and efficiently break through the glass curtain wall of a high-rise building for fire fighting and rescue. The device mainly includes: a telescopic boom 10, a basket 20 installed at the end of the telescopic boom, a drive assembly 30 installed in the basket, an impact head 40 connected to the drive assembly, and an adsorption mechanism 50 for adsorbing the window breaking device onto the glass curtain wall.

[0024] The telescopic boom 10 is primarily used to vertically raise and lower the window-breaking device from the top of a high-rise building to the target floor. In this embodiment, the telescopic boom 10 preferably adopts a structure consisting of a drive motor 11, two scissor-type guide mechanisms 12 arranged parallel in the vertical direction, and two rigid chains 13. The drive motor 11 precisely controls the extension and retraction length of the rigid chains 13, thereby driving the scissor-type guide mechanisms 12 to extend or retract, thus achieving smooth raising and lowering of the telescopic boom 10. This structure not only has a high load-bearing capacity, but also, in conjunction with the guidance of the scissor-type guide mechanisms 12, effectively reduces the impact of external factors such as wind on the stability of the boom.

[0025] In this embodiment, the suspended platform 20 is fixedly installed at the end of the telescopic boom 10 to support components such as the drive assembly 30, the impact head 40, and the adsorption mechanism 50, and to provide an installation platform and operating space for these components. In this embodiment, the suspended platform 20 may be made of high-strength alloy material to ensure that it has sufficient load-bearing capacity, and the size of the suspended platform should be designed according to actual needs to meet the installation requirements of the internal components.

[0026] The impact head 40 is connected with the driving assembly 30 and can reciprocate between a first position and a second position under the driving of the driving assembly 30, the second position is located outside the vertical projection of the basket 20, and the purpose is to enable the impact head 40 to effectively contact and break the outer surface of the glass window of the target floor; in the embodiment, the impact head 40 is preferably made of a high-hardness and wear-resistant material, such as tungsten steel or alloy steel, to ensure that it has sufficient impact force and service life.

[0027] In addition, when the basket 20 reaches the target floor, the suction mechanism 50 is extended and adsorbed on the outer wall of the building or the glass to be broken before the driving action of the driving assembly 30. The main purpose of the suction mechanism 50 is to provide stable and reliable support for the entire window breaking device, effectively prevent it from shaking or deviating when impacting the glass, avoid the deviation of the impact head due to shaking, and affect the window breaking efficiency. In the embodiment, the suction mechanism 50 can adopt a telescopic pneumatic suction disc structure which is simple in structure, strong in adsorption force and easy to control. Specifically, a plurality of suction discs form a local vacuum with the surface of the glass curtain wall, generate a strong adsorption force, and thus firmly fix the entire window breaking device on the outer wall of the building, form a stable connection, effectively reduce the shaking of the basket 20 in the air caused by wind and other factors, and thus reduce the reaction force during window breaking, so that the driving assembly 30 can more easily drive the impact head 40, improve the window breaking efficiency, and provide a channel for subsequent fire extinguishing operations.

[0028] In some embodiments, the driving assembly 30 drives the impact head 40 to move in any of the following ways: swing in a circular path between the first position and the second position, reciprocate in a straight line between the first position and the second position, or launch the impact head 40 from the first position to the second position and return it to the first position through a recovery mechanism. Among them, the swing driving is suitable for window breaking scenes that require a larger acting area, for example, when it is necessary to quickly clean a larger area of broken glass, the swing angle and frequency can be adjusted to make the impact head 40 repeatedly hit the glass, thereby accelerating the breaking of the glass; the reciprocating driving is suitable for window breaking scenes that require accurate impact, for example, when it is necessary to quickly break a double or multi-layer glass curtain wall, the straight-line reciprocating motion can be used to concentrate the force on the glass, thereby improving the window breaking efficiency; and the launching driving is suitable for scenarios that require long-distance window breaking, for example, when there are obstacles outside the building, or when it is necessary to avoid the impact head 40 from colliding with the building, the impact head 40 can be launched to the target position for window breaking through the launching mode, and the impact head 40 is safely recovered through the recovery mechanism.

[0029] The specific driving mode can be selected flexibly according to the actual deployment of the building facade style to ensure that the glass curtain wall can be quickly and effectively broken in an emergency. More importantly, the design advantage lies in ensuring the recycling of the impact head 40, thereby effectively avoiding the safety hazards that may be caused by the unexpected loss of the impact head 40 and the interruption of rescue caused thereby, and ensuring the continuous operation of the window breaking operation.

[0030] In a specific embodiment, as shown in Figure 1 , Figure 4 , the driving assembly 30 is a multi-degree-of-freedom mechanical arm, the impact head 40 is a striker mounted at the end of the mechanical arm, and the front end of the striker is provided with a conical needle.

[0031] Specifically, the multi-degree-of-freedom mechanical arm can realize multi-angle and multi-directional movement, and can flexibly adjust the position and posture of the striker, thereby adapting to different shapes of window frames and avoiding obstacles, ensuring that the striker can accurately hit the impact point of the glass. Even if the position of the target window is irregular, inclined, or blocked by other objects, the mechanical arm can flexibly adjust the posture to ensure that the striker can smoothly contact the glass surface, so as to cope with various complex glass curtain wall structures and improve the efficiency and success rate of window breaking.

[0032] In some embodiments, as shown in Figure 1 , Figure 4 , the end of the mechanical arm is provided with a high-pressure spray head 60 for fire extinguishing, and the high-pressure spray head 60 is connected to an external fire water source through a water supply pipe 61. In this way, after the mechanical arm drives the striker to quickly break the glass curtain wall and creates conditions for the fire extinguishing agent to enter the room, the mechanical arm quickly adjusts the posture, aims the high-pressure spray head 60 at the fire source, and starts spraying. Because the mechanical arm has multiple degrees of freedom, the high-pressure spray head 60 can realize multi-directional movement such as up and down, left and right, and front and back, and can aim at any angle of the fire source to realize three-dimensional precise fire extinguishing.

[0033] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 3 , a guide rail 70 and a rotating support 71 are further included, the guide rail 70 is fixed to the top of the high-rise building and extends along the outer edge of the high-rise building, the rotating support 71 is movably assembled on the guide rail 70, the rotating support 71 is provided with a telescopic support arm 72, the telescopic support arm 72 at least partially extends out of the high-rise building, and the top end of the telescopic hoist arm 10 is connected to the distal end of the telescopic support arm 72 extending out of the outer edge of the high-rise building.

[0034] With this structural design, the guide rail 70 provides a moving path for the rotating support 71, enabling it to move freely along the outer edge of the building, thus covering various facades of the building. The rotating support 71 can move along the guide rail 70 and rotate, allowing adjustment of the breaking window angle. The telescopic support arm 72 is arranged on the rotating support 71 and is used to support the telescopic boom 10 and adjust the distance between the telescopic boom 10 and the outer facade of the building. For example, when the fire source is located at a corner of the building, the rotating support 71 can move to the appropriate position along the guide rail 70 and adjust the direction by rotating, so that the telescopic boom 10 can accurately reach the target position for breaking windows and fire extinguishing operations. This design greatly improves the coverage and flexibility of the fire breaking window device.

[0035] Specifically, as shown in Figure 1 、 Figure 2 , the telescopic boom 10 includes a driving motor 11, two vertically parallel arranged scissor-type guide mechanisms 12, and two rigid chains 13 arranged between the two scissor-type guide mechanisms 12, forming a compact overall structure. The telescopic support arm 72 is provided with two parallel chain boxes 14, the driving motor 11 is arranged at the distal end of the telescopic support arm 72 and located between the two chain boxes 14. The driving motor 11 is connected with the sprocket in the chain box 14 through a double shaft transmission mechanism, the top ends of the two rigid chains 13 extend into the corresponding chain box 14 and mesh with the corresponding sprocket. The distal end of the telescopic support arm 72 is provided with a hanging seat 15 opposite to the hanging basket 20, the hanging seat 15 is provided with a guide hole for the rigid chain 13 to pass through, the upper end of the scissor-type guide mechanism 12 is fixedly connected with the hanging seat 15, and the lower end is fixedly connected with the hanging basket 20. In actual application, when high-altitude fire extinguishing is needed, the driving motor 11 is started, the sprocket is driven to rotate through the double shaft transmission mechanism, and then the rigid chain 13 is driven to extend or retract, the extension and retraction of the rigid chain 13 directly drives the scissor-type guide mechanism 12 to expand or contract, thereby driving the hanging basket 20 to realize precise lifting movement. Because the rigid chain has high strength and rigidity, the hanging basket 20 can remain stable even in strong wind environment, ensuring the smooth progress of breaking window and fire extinguishing operations.

[0036] In some embodiments, as Figure 2As shown, the rotating support 71 is provided with a water storage tank 73, which is communicated with the high-pressure nozzle 60 through a water supply pipe 61; the telescopic support arm 72 is provided with a pipe winder 74, which is adaptively connected with the water supply pipe 61, and is used to wind and unwind the water supply pipe 61 along with the lifting movement of the basket 20. In specific implementation, the water storage tank 73 is provided with a quick connector, so as to be quickly connected with an external fire-fighting water source, and at the same time, a certain amount of fire-fighting water is pre-stored in the water storage tank 73, so as to ensure that the initial fire extinguishing can be performed by using the self-carried water source before the fire-fighting rescue force arrives at the scene, thereby rapidly controlling the spread of the fire and gaining valuable time for subsequent rescue. In addition, the arrangement of the pipe winder 74 can solve the problem of length change of the water supply pipe 61 during the lifting movement of the basket 20, and can ensure smooth water supply while avoiding the winding or breakage of the water supply pipe 61 due to excessive length, thereby affecting the reliability of the fire extinguishing operation. In addition, the water tank 60 is arranged on the rotating support 71, which not only can effectively utilize the space, but also can add counterweight to the rotating support 71, thereby significantly improving the stability of the entire device during high-altitude operation and reducing the safety risk.

[0037] In some embodiments, as Figure 1 As shown, the distal end of the telescopic support arm 72 is pivotally connected with a guide pulley 75, and the water supply pipe 61 passes through the guide pulley 75 and is communicated with the high-pressure nozzle 60. In this way, the guide pulley 75 plays a buffering role, and when the telescopic support arm 10 moves up and down, the water supply pipe 61 does not directly bend, but slides along the arc of the guide pulley 75, thereby greatly reducing the bending stress borne by the water supply pipe 61 and avoiding the risk of pipe wall damage and leakage caused by excessive bending.

[0038] The glass curtain wall window breaking fire-fighting device provided by the embodiment can effectively overcome the limitations of conventional fire-fighting equipment in terms of operation height, traffic accessibility and environmental adaptability, and the device can quickly reach the target floor and be firmly fixed on the surface of the glass curtain wall through the adsorption mechanism, and can maintain stability even in the face of double-layer glass curtain wall structure, and can efficiently break the glass through the integrated window breaking device, and quickly open a channel for the fire extinguishing agent to enter the fire scene, thereby realizing timely fire control. This design not only effectively prevents the spread of fire, but also maximizes the safety of personnel life and property, and provides a more reliable, efficient and practical technical solution for high-rise building fire safety.
