Description

Technical Field

[0001] This utility model relates to the field of smoke simulation technology, and in particular to a smoke simulation device for building fire protection testing. Background Technology

[0002] With the acceleration of urbanization and the increase in high-rise buildings, fire safety issues are becoming increasingly prominent. Smoke is one of the main causes of casualties during a fire. Therefore, as the core equipment of the fire early warning system, the performance and reliability of smoke detectors are directly related to the emergency response speed and the success rate of personnel escape during a fire. However, traditional smoke detector detection methods are usually limited to testing in static environments and cannot truly simulate the dynamic smoke diffusion and personnel escape scenarios at a fire scene. Existing fire drill equipment is mostly single-function and cannot meet the performance testing of smoke detectors. The smoke generated by the smoke generators is often not realistic enough, resulting in poor drill effects and even potential safety hazards. Therefore, developing a comprehensive fire test device that can simulate a real fire smoke environment and test the performance of smoke detectors is of great practical significance. Currently, most existing smoke simulation devices on the market use simple smoke generators, resulting in uneven smoke diffusion and a lack of detection capabilities for the dynamic response of smoke alarms. These devices are insufficient to meet the high standards required for modern fire protection testing and drills. Therefore, there is an urgent need for an intelligent fire protection testing device that integrates smoke simulation and alarm detection to improve the testing efficiency of fire protection equipment and provide strong support for fire prevention and emergency response.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0021] A smoke simulation device for building fire protection testing, such as Figures 1 to 7 As shown, the device includes a simulation chamber 1 and an alarm detection assembly. A smoke exhaust assembly is installed on the top of the simulation chamber 1, and a smoke generator 11 is fixed to the inner wall of one side of the simulation chamber 1. The alarm detection assembly includes a slide rail 12 and a sliding seat 19. The slide rail 12 is fixed between the inner walls of the two sides of the simulation chamber 1 by bolts, and the sliding seat 19 is slidably connected to the outer wall of the slide rail 12. A rotating ring 20 is rotatably connected between the two sliding seats 19, and a pad 21 is fixed to the bottom of the rotating ring 20. A connecting rope 23 is fixed to the bottom of the pad 21, and an installation plate 38 is installed at the bottom of the connecting rope 23. A waist binding mechanism is fixed to the side wall of the installation plate 38, and a smoke alarm 37 is installed on the waist binding mechanism. The simulation chamber 1 can simulate an indoor environment. The smoke generator 11 generates smoke after it is turned on. In this embodiment, the smoke generator 11 is preferably an atomizing type powered by a battery. It atomizes the liquid into tiny particles to form smoke through ultrasonic waves or high-pressure airflow. Its working principle is as follows: the liquid, usually water-based or glycerin-based smoke liquid, is injected into the atomizing device. Ultrasonic waves or high-pressure airflow decompose the liquid into tiny particles. These particles are suspended in the air to form a smoke-like effect. It is non-toxic, environmentally friendly, and suitable for indoor space drills. When a fire test needs to be simulated, the tester enters the simulation chamber 1 and puts on the waist restraint mechanism. The tester moves inside the simulation chamber 1. During the movement, the waist restraint mechanism drives the smoke alarm 37 to move synchronously. At the same time, the smoke generator 11 is activated to generate smoke. In this embodiment, the smoke generator 11 is preferably photoelectric. When the smoke alarm 37 detects smoke, it issues an alarm. The simulation can be performed to see if the smoke alarm 37 can issue an alarm when smoke is present. At the same time, the smoke alarm 37 moves continuously, and its alarm response rate at different locations can be detected to ensure that the smoke alarm 37 can issue an alarm in time when a fire occurs in actual use to ensure fire safety. Meanwhile, the testing personnel can move inside the simulation chamber 1 and conduct escape simulations in conjunction with the smoke generator 11. That is, when smoke appears, they can move from one end of the simulation chamber 1 to the other end to improve their psychological quality and escape experience in the event of a fire, thereby increasing the probability of escape when a fire occurs in reality.

[0022] The waist binding mechanism includes a strap 22, a hook and loop fastener 33, and a smooth hook and loop fastener 34. The strap 22 is fixed to the side wall of the mounting plate 38 by adhesive bonding. The smooth hook and loop fastener 34 and the hook and loop fastener 33 are respectively sewn to both sides of the strap 22, and the hook and loop fastener 33 and the smooth hook and loop fastener 34 are used together. When the waist binding mechanism needs to be worn around the waist, after wrapping the binding strap 22 around the waist, the hook and loop fastener 33 and the smooth hook and loop fastener 34 are glued together to fix the binding strap 22 to the waist.

[0023] A push-button alarm 32 is fixed to the side wall of the strap 22, and a fog light 31 is installed on the top of the mounting plate 38; Once the testing personnel enter the simulation chamber 1, to ensure safety, if they feel unwell, they can press the push-button alarm 32 to sound an alarm so that support personnel outside the simulation chamber 1 can quickly enter and provide assistance. The fog light 31 helps support personnel quickly locate the testing personnel after they enter the simulation chamber 1. The fog light 31 and the push-button alarm 32 are preferably battery powered. The push-button alarm 32 works by consisting of a pressable switch or button. When this button is pressed, the internal circuit of the alarm is activated. After the circuit is connected, a specific current or voltage change is generated. This change is detected by the internal sensor, which outputs the signal after receiving it.

[0024] Both sides of the simulation cabin 1 are connected to safety doors 2 via hinges; Safety door 2 facilitates the entry of testing personnel into the simulation chamber 1. By setting up two sets of safety doors 2, testing personnel can enter from one side of the simulation chamber 1 and exit from the other side.

[0025] The smoke extraction assembly includes an air pump 4, an exhaust hood 6, and a support plate 7. The exhaust hood 6 is fixed to the top of the simulation chamber 1, and the support plate 7 is fixed to the top of the simulation chamber 1 by bolts. The air pump 4 is installed on the outer wall of the support plate 7, and a solenoid valve 8 is fixed to one end of the air pump 4. The solenoid valve 8 and the exhaust hood 6 are connected by an exhaust pipe 5. Once the simulation is complete, open the solenoid valve 8 and use the air pump 4 to extract the smoke from inside the simulation chamber 1, thereby preventing the smoke from accumulating inside the simulation chamber 1.

[0026] The bottom inner wall of the simulation cabin 1 is respectively fixed with a barrier plate 13 and a stepped obstacle 14; By setting up barrier panels 13 and stepped obstacles 14, stairs and obstacles in an indoor environment can be simulated, improving the realism of the environmental simulation.

[0027] A control panel 3 is installed on one outer wall of the simulation cabin 1; The control panel 3 is used to control the entire device, including controlling the start of the air pump 4, solenoid valve 8 and smoke generator 11, as well as receiving and displaying signals from the push-button alarm 32 and smoke alarm 37. When the smoke alarm 37 detects smoke, it will emit an alarm signal. This signal is an electrical signal that is transmitted wirelessly to the control panel 3. The control panel 3 should have a corresponding receiving module to receive and process this signal. When the person being tested feels unwell and presses the push-button alarm 32, the signal output by the push-button alarm 32 is also received by the receiving module of the control panel 3 via wireless transmission.

[0028] Working Principle: The simulation chamber 1 can simulate an indoor environment for fire detection drills. A smoke generator 11 is fixed to one inner wall of the simulation chamber 1, creating a non-toxic and environmentally friendly smoke effect to simulate a fire scene. After entering the simulation chamber 1, the testing personnel wear the waist restraint mechanism. Through the design of the slide rail 12 and sliding seat 19, the testing personnel can move freely inside the simulation chamber 1, simultaneously driving the smoke alarm 37 to move synchronously. When the smoke generator 11 is activated and produces smoke, the smoke alarm 37 will monitor the smoke and sound an alarm, simulating the response of the smoke alarm during an actual fire. By continuously moving the smoke alarm 37, its alarm response rate at different locations can be detected. A push-button alarm 32 is fixed to the side wall of the simulation chamber 1. When the testing personnel feel unwell, they can press the alarm to send a distress signal to the external support personnel. A fog light 31 is installed on the top of the mounting plate 38 to facilitate the support personnel to quickly spot the testing personnel after entering the simulation chamber 1. Both sides of the simulation chamber 1 are connected to safety doors 2 by hinges to facilitate the entry and exit of the testing personnel. After the simulation is completed, the solenoid valve 8 is opened through the control panel 3, and the air pump 4 is used to extract the smoke inside the simulation chamber 1 from the exhaust hood 6 through the exhaust pipe 5 to prevent smoke accumulation. The bottom inner wall of the simulation chamber 1 is fixed with a barrier plate 13 and a stepped barrier 14 to simulate stairs and obstacles in the indoor environment to improve the realism of the simulation. Example 2

[0029] A smoke simulation device for building fire protection testing, in order to further ensure operational safety, such as... Figures 1 to 7 As shown, this embodiment makes the following additions based on embodiment 1: a rotating column 24 is rotatably connected between the two sliding seats 19, and a reel 10 is fixed to the outer circumference of the rotating column 24 by a pin, and a safety rope 26 is wound around the outer circumference of the reel 10, and a coil spring 18 is installed between the outer circumference of the rotating column 24 and the side wall of the sliding seat 19; a tension sensor 15 is fixed to one side of the inner wall of the simulation cabin 1 by screws, and the tension sensor 15 and the end of the safety rope 26 away from the reel 10 are fixedly connected; As the testing personnel move inside the simulation chamber 1, the end of the safety rope 26 away from the reel 10 is fixed to the tension sensor 15. Therefore, when the testing personnel move, as the sliding seat 19 slides along the slide rail 12, the rotating column 24 and the reel 10 rotate along the sliding seat 19 to unwind the safety rope 26. During this process, the tension sensor 15 will monitor the tension applied by the safety rope 26. In this way, the support personnel can determine that the testing personnel are in a moving state. If the testing personnel fall and cannot move due to an accident, or faint due to physical discomfort and cannot press the push-button alarm 32, the tension value detected by the tension sensor 15 will tend to stabilize, thereby reminding the support personnel to enter the simulation chamber 1 for rescue and ensure the safety of the testing personnel. Specifically, the tension sensor 15 and the control panel 3 are electrically connected. The tension sensor 15 converts the detected tension into an electrical signal. The control panel 3 is based on a programmable logic control panel (PLC), which has input / output channels and data processing capabilities. The control panel 3 and the tension sensor 15 communicate wirelessly for signal transmission. The control panel 3 receives the signal from the tension sensor 15, processes the data, and makes corresponding control decisions. One or more tension thresholds are set in the program to determine the state of the personnel being tested, such as normal movement, falling, or fainting. The signal from the tension sensor 15 is monitored in real time and compared with the set thresholds. When the tension value is stable and below or above a certain threshold, an alarm signal is triggered, and the support personnel are notified to carry out rescue.

[0030] A connecting plate 16 is fixed to one side of the inner wall of the simulation chamber 1 by bolts, and a T-shaped rod 17 is slidably connected to the through hole on the surface of the connecting plate 16. A spring 28 is snapped between the top inner wall of the T-shaped rod 17 and the top outer wall of the connecting plate 16. A U-shaped frame 29 is welded to the bottom of the T-shaped rod 17, and a support roller 27 is rotatably connected to the inner wall of the U-shaped frame 29. A bracket 25 is fixed to one side of the inner wall of the simulation chamber 1 by bolts, and a support roller 30 is rotatably connected to the inner wall of the bracket 25. The elastic force of spring 28 enables support roller 27 and support roller 30 to support safety rope 26.

[0031] A buffer mechanism is installed on one side of the inner wall of the simulation chamber 1. The buffer mechanism includes a mounting cylinder 9 and a buffer rod 36. The mounting cylinder 9 is fixed to the inner wall of one side of the simulation chamber 1 by bolts, and the buffer rod 36 is slidably connected to the inner wall of the through hole opened at one end of the mounting cylinder 9. A spring 35 is engaged between the outer wall of one side of the buffer rod 36 and the inner wall of one side of the mounting cylinder 9. After the tester moves from one side of the simulation chamber 1 to the other side, when the waist restraint mechanism is released from the waist, the spring force of the coil spring 18 allows the sliding seat 19 to move in the opposite direction along the slide rail 12 to reset. When the sliding seat 19 moves to contact the buffer rod 36, the spring 2 35 can buffer and protect the sliding seat 19.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
