Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a large-scale public building fire emergency escape detection equipment and a use method thereof. Background Art

[0002] At present, compared with ordinary buildings, large public buildings have more complex structures, more densely populated people, and more concentrated wealth. Fires have a higher outbreak rate in emergencies in large public buildings. The incidence of fires has been rising in recent years at home and abroad. The economic losses and casualties caused by fires have attracted widespread attention from the society. Once a fire occurs, it often causes serious casualties and property losses. Therefore, the research and development and application of fire emergency escape detection equipment for large public buildings is particularly important.

[0003] In existing fire detection equipment, the air intake is a key component, and its role is to extract air samples from the fire scene for sensor analysis. However, the existing air intake design has obvious limitations, that is, they can usually only extract air samples from a fixed direction. Since the air intake can only extract air from a fixed direction, there are detection blind spots in other areas inside the building. These blind spots may be areas where the fire develops faster, or areas with high concentrations of smoke and harmful gases. If the fire situation in these areas cannot be detected in time, it will seriously affect the efficiency of fire emergency escape. Summary of the invention

[0004] The purpose of the present invention is to provide a large public building fire emergency escape detection device and a method of use, so as to solve the obvious limitations of the existing air intake cylinder design mentioned in the above background technology, that is, they can usually only draw air samples from one fixed direction. Since the air intake cylinder can only draw air from a fixed direction, there are detection blind spots in other areas inside the building. These blind spots may be areas where the fire develops faster, or areas with high concentrations of smoke and harmful gases. If the fire situation in these areas cannot be detected in time, the efficiency of fire emergency escape will be seriously affected.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a large public building fire emergency escape detection equipment, comprising a base, a box body fixedly installed at the bottom of the base, a sensor array fixedly installed inside the box body, an air intake cylinder arranged at the center of the bottom of the box body, a chassis 2 fixedly installed at the bottom of the air intake cylinder, a variable frequency motor fixedly installed inside the chassis 2, a connecting rod fixedly connected to the output end of the top of the variable frequency motor, the top of the connecting rod penetrates into the interior of the air intake cylinder, a slide rail is provided at the top position and the top position of the air intake cylinder, an annular slide plate is slidably connected inside the slide rail, a fixing rod is fixedly connected at the top and the center position of the surface of the connecting rod, a side of the fixing rod away from the connecting rod is fixedly connected to the inner wall of the annular slide plate, an annular plate is fixedly connected to the outer wall of the annular slide plate, the annular plate is sleeved with the air intake cylinder, an air intake hole is provided at the center of the front surface of the annular plate, and a plurality of air intake grooves are provided at the center position of the outer surface of the air intake cylinder.

[0006] Preferably, the sensor array includes a smoke sensor, a temperature sensor, a flame detector, a gas sensor and an infrared thermopile array sensor.

[0007] Preferably, alarms are fixedly mounted on both sides of the top of the box, and the bottom of the alarm is connected to the sensor array.

[0008] Preferably, the center of the top of the air intake cylinder is connected to an exhaust pipe, and the top of the exhaust pipe is connected to the center of the bottom of the box.

[0009] Preferably, a chassis 1 is fixedly installed at the center between the box body and the base, a suction fan is fixedly installed inside the chassis 1, the bottom of the chassis 1 is connected to the top of the box body, the top of the chassis 1 is connected to an air outlet duct, and the top of the air outlet duct passes through to the outside of the base.

[0010] Preferably, the four corners of the base are all threadedly connected with mounting bolts, and the tops of the mounting bolts penetrate to the outside of the base.

[0011] Preferably, iron strips are fixedly connected to both sides of the bottom of the fixing member, and a magnetic strip is fixedly connected to the bottom of the side plate, and the magnetic strip is magnetically connected to the iron strip.

[0012] Preferably, a handle is fixedly connected to the top of the fixing member.

[0013] A method for using a large public building fire emergency escape detection device comprises the following steps:

[0014] Step 1: First, fix the base to the appropriate location of the large public building with mounting bolts to ensure that the equipment is stable and easy to detect fire conditions.

[0015] Step 2. When a fire occurs, the suction fan starts, the variable frequency motor starts, and the annular slide plate is driven to slide and rotate in the slide rail through the connecting rod and the fixed rod. The rotation of the annular slide plate drives the annular plate to rotate. The annular plate can adjust its direction as needed to extract air samples from different angles, thereby detecting the fire more comprehensively and better collecting air samples at the fire scene.

[0016] Step 3: The air sample at the fire scene enters the air intake cylinder through the air intake hole and the air intake slot, and then enters the interior of the box through the exhaust pipe. Inside the box, the sensor array further detects and analyzes the air sample. When the sensor array detects any abnormal data, such as excessive smoke concentration, abnormal temperature rise, flame, excessive concentration of harmful gases or abnormal thermal radiation, the sensor transmits the signal to the alarm. After receiving the signal, the alarm will immediately start the alarm program and send out sound and light alarm signals to remind people to evacuate.

[0017] Step 4: The air outlet duct discharges the air inside the box to form an air circulation. Once the equipment detects a fire and starts the alarm program, it will connect with the building's emergency escape system to provide accurate fire location and escape route guidance to help people evacuate the fire quickly and safely.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The large public building fire emergency escape detection device has a connection mechanism, and a variable frequency motor drives the annular slide plate and the annular plate to rotate in the air intake cylinder. The present invention allows air samples to be extracted from multiple angles, thereby eliminating the detection blind area caused by the existing air intake cylinder that can only extract air samples from a single direction. This means that no matter from which direction the fire spreads, or in which area the smoke and harmful gases accumulate, the present invention can detect them in time, greatly improving the comprehensiveness and accuracy of fire detection. Since the equipment has the ability to extract air samples from multiple angles, even in the early stage of the fire, before the fire spreads to the location of the equipment, the existence of the fire can be detected through air samples in other areas, which greatly shortens the time for the fire to be discovered, improves the response speed of the equipment, and gains precious time for fire emergency treatment. The sensor array contains multiple sensors, which can simultaneously detect and analyze multiple parameters in the air sample. By comprehensively judging the changes in multiple parameters, the equipment can more accurately judge whether a fire has occurred, as well as the scale and scope of the fire, providing more reliable guidance for emergency escape.
