Description

Technical Field

[0001] This utility model relates to the field of dormitory safety, specifically to an automatic fire extinguishing bed that integrates detection and extinguishing functions. Background Technology

[0002] Dormitory safety has always been a crucial aspect of university management. The suddenness and destructive nature of fires make dormitory beds a key potential area for fire spread. Current technologies for controlling student dormitory fires generally rely on monitoring and alarm systems, issuing an alarm upon detection of a fire and then initiating automatic or manual firefighting operations. While mature automatic sprinkler systems exist, installing them in older dormitories is challenging due to hardware limitations, leading to significant fire control pressures. Therefore, there is an urgent need to develop a precision fire suppression system specifically designed for university dormitory beds. Utility Model Content

[0003] This utility model provides an automatic fire-extinguishing bed that integrates detection and extinguishing functions to solve the problem that it is difficult to install automatic sprinkler fire extinguishing systems in old dormitories and that fire control is under great pressure in the existing technology. It achieves the purpose of early warning and initial fire extinguishing for fires occurring on dormitory beds.

[0004] This utility model is achieved through the following technical solution:

[0005] An integrated automatic fire extinguishing bed includes a bed frame and a fire extinguishing assembly connected to the bed frame. The fire extinguishing assembly includes a housing, a fire extinguishing agent storage device located inside the housing, a spraying device connected to the fire extinguishing agent storage device, and a control device for controlling the opening and closing of the spraying device. The spraying direction of the spraying device is towards the bed frame. The fire extinguishing assembly also includes a fire monitoring assembly, which is signal-connected to the input terminal of the controller, and the output terminal of the controller is signal-connected to the control device.

[0006] To address the challenges of installing automatic sprinkler systems in older dormitories and the resulting pressure on fire control, this invention proposes an integrated fire-fighting bed with both detection and extinguishing capabilities. The bed frame can utilize existing technology. This application connects a detection and extinguishing component to the existing bed frame. This component includes a housing containing a fire extinguishing agent storage device and a spraying device pointing towards the bed frame. In operation, the fire monitoring component detects whether a fire has occurred in the direction of the bed frame and transmits the monitoring results to a controller. Under normal conditions, the control device remains off. When the controller receives a fire signal, it activates the control device, turning on the spraying device to spray fire extinguishing agent towards the bed frame, thus providing initial fire suppression, delaying the spread of the fire, and buying more time for manual firefighting. This invention requires no modification to the dormitory's hardware; only a suitably sized detection and extinguishing component needs to be installed on the existing bed frame. This reduces the difficulty of fire control in older dormitories and achieves the goal of early warning and initial fire suppression for fires occurring in dormitory beds.

[0007] In this application, the extinguishing agent storage device can store any extinguishing agent material in the prior art; the control device can be implemented by any device in the prior art that can control the opening and closing of the spray device; the fire monitoring component can be implemented by any device in the prior art that can sense or monitor fire; the controller can be implemented by existing mature equipment, such as single-chip microcomputers, PLC and other control modules.

[0008] Furthermore, the extinguishing agent storage device is a pressure vessel, and the control device is a discharge valve matched with the pressure vessel. This solution uses a pressure vessel as the extinguishing agent storage device, eliminating the need for additional power equipment and reducing equipment size and footprint. Under normal conditions, the discharge valve is kept closed; when fire extinguishing is required, the discharge valve is opened.

[0009] Furthermore, the spraying device includes a nozzle and a plurality of spray holes formed on the nozzle. When the control device is turned on, the extinguishing agent enters the nozzle from the extinguishing agent storage device and is sprayed out from each spray hole, which helps to improve the uniformity of the extinguishing agent spray.

[0010] Furthermore, the fire monitoring component includes a smoke sensor and a temperature sensor. During the research process, the inventors discovered that using either a smoke sensor or a temperature sensor alone carries a significant risk of false alarms. Therefore, this solution uses both smoke and temperature sensors simultaneously to collaboratively determine the occurrence of a fire. When the smoke concentration exceeds a preset threshold or the temperature abnormally rises to a dangerous level, a fire is identified. This method reduces the probability of false alarms and improves the accuracy of early warnings.

[0011] Furthermore, the fire monitoring component also includes an infrared thermal imaging probe, which can capture and analyze the heat distribution around the bed frame, thereby accurately locating the fire source and sending the location information of the fire area to the controller, enabling the controller to more accurately control the operation of the corresponding spray device.

[0012] Furthermore, a snap-fit ​​assembly is connected to the side of the housing, which is used to fasten to the edge of the bed frame. This solution achieves a detachable connection between the housing and the bed frame through the snap-fit ​​assembly, facilitating the replacement or maintenance of the housing and fire extinguishing agent storage device, etc. The specific structure of the snap-fit ​​assembly is not limited here, as long as it matches the corresponding bed frame and can be snapped to the edge of the existing bed frame in the dormitory.

[0013] Furthermore, the buckle assembly includes several C-shaped fasteners fixed to the top side of the box body. Student dormitory bed frames typically have at least two railings; this solution uses C-shaped fasteners to fasten the frame to the top railing. The C-shaped fasteners have an anti-fall function to prevent the box body from falling and are also easy to disassemble and replace.

[0014] Furthermore, the buckle assembly also includes several L-shaped fasteners located below the C-shaped fastener, which are fastened upside down onto the railing below to improve the installation stability of the detection and extinguishing assembly.

[0015] Furthermore, the bed frame is a double- or triple-layer structure, with each layer of the bed frame connected to the fire detection and extinguishing components; thus, this application better meets the fire prevention and extinguishing needs of existing student dormitories.

[0016] Furthermore, each layer of the bed frame is connected to the detection and extinguishing components at both the head and foot of the bed.

[0017] Compared with the prior art, this utility model has at least the following advantages and beneficial effects:

[0018] 1. This utility model provides an automatic fire-extinguishing bed with integrated detection and extinguishing capabilities. It does not require any modification to the dormitory's hardware.

Therefore, they should not be construed as limiting the scope of protection of this application.

[0029] Example 1:

[0030] like Figures 1 to 3The illustrated automatic fire extinguishing bed includes a bed frame 1 and a fire extinguishing assembly connected to the bed frame 1. The fire extinguishing assembly includes a housing 2, a fire extinguishing agent storage device 3 located inside the housing 2, a spraying device connected to the fire extinguishing agent storage device 3, and a control device 4 for controlling the opening and closing of the spraying device. The spraying direction of the spraying device is towards the bed frame 1. The fire extinguishing assembly also includes a fire monitoring component, which is signal-connected to the input terminal of the controller, and the output terminal of the controller is signal-connected to the control device 4.

[0031] like Figure 1 As shown, the bed frame 1 in this embodiment has a double-layer structure, and each layer of the bed frame 1 is connected to the detection and extinguishing components; each layer of the bed frame 1 is connected to the detection and extinguishing components in the head and foot directions.

[0032] In this embodiment, the extinguishing agent storage device 3 is a pressure vessel. For safety reasons, the housing 2 is installed inside the hollow area of ​​the bed frame, and can be normally covered by other materials such as bed boards and cabinets. The extinguishing agent used in the extinguishing agent storage device 3 can be dry powder, water, or inert gas, etc.

[0033] In this embodiment, the control device 4 is a release valve that matches the pressure vessel, preferably a solenoid valve.

[0034] The spraying device in this embodiment includes a spray pipe 5 and a plurality of spray holes 6 formed on the spray pipe 5; a nozzle, such as an atomizing nozzle, may also be installed on the spray holes 6. It should be noted that... Figure 1 To better showcase the spraying device, the bed frame railings and fire monitoring components corresponding to the fire detection and extinguishing components in the lower left corner have been omitted.

[0035] The controller in this embodiment is implemented using a microcontroller, such as an STM32F microcontroller module.

[0036] When the controller in this embodiment receives a fire signal, the control device 4 is activated and the spraying device is turned on. The spraying device sprays fire extinguishing agent in the direction of the bed frame to initially extinguish the fire and delay its spread. At the same time, the controller can also send fire alarm information to dormitory management personnel and / or fire departments wirelessly or via wired means.

[0037] In a more preferred embodiment, each housing 2 is provided with two fire extinguishing agent storage devices 3, which are connected to the nozzle 5 via a tee connector; the corresponding discharge valve is installed on the pipeline between the tee connector and the nozzle 5.

[0038] In addition, all electrical equipment in this application is powered by existing power supply methods, such as the mains power supply inside the dormitory, or a battery for each detection and extinguishing component.

[0040] An automatic fire extinguishing bed integrating detection and extinguishing functions, based on Example 1, such as... Figures 1 to 3 As shown, the fire monitoring component includes a smoke sensor 7 and a temperature sensor 8. The smoke sensor, as a primary early warning element, detects the concentration of smoke particles in the air around the bed. Once the smoke concentration exceeds a preset threshold, it immediately sends a primary early warning signal to the controller. The temperature sensor, as a secondary early warning element, uses a thermistor or thermocouple and is located in the first hole of the bed frame to monitor temperature changes around the bed. When the temperature abnormally rises to a dangerous level, it works in conjunction with the smoke sensor signal to determine the fire situation.

[0041] Preferably, the smoke sensor 7 is a high-sensitivity photoelectric or ionization sensor, such as the MQ-2 smoke sensor module; the temperature sensor 8 is a thermistor or thermocouple sensor, such as the PT-100 platinum resistance temperature sensor.

[0042] In a more preferred embodiment, the fire monitoring component further includes an infrared thermal imaging probe 9, such as the MLX90640BAA / B thermal infrared sensor module; this facilitates accurate location of the fire and sends the location information of the fire area to the controller.

[0043] In a more preferred embodiment, a snap-fit ​​assembly is connected to the side of the housing 2, the snap-fit ​​assembly being used to fasten to the edge of the bed frame 1. In this embodiment, the snap-fit ​​assembly includes several C-shaped fasteners 10 fixed to the top of the side of the housing 2, and L-shaped fasteners 11 located below the C-shaped fasteners 10.

[0044] In a more preferred embodiment, each nozzle 5 corresponds to a fire monitoring component; and the nozzle 5 is located between the corresponding C-shaped fastener 10 and L-shaped fastener 11.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
