Description
Technical Field
[0001] The utility model relates to the field of fire detection, in particular to a fire detection hot smoke generating device. Background Art
[0002] The inspection of building fire protection facilities is to use specified methods to test the specific technical performance indicators of building fire protection facilities for each system of building fire protection facilities to determine whether the building fire protection facilities meet the indicators specified in the specifications and requirements, and ensure that the building fire protection facilities can achieve the expected use effect. When a fire or other fire accident occurs indoors, smoke will be generated. At this time, smoke sensors are needed to sense, alarm and spray water in time. Smoke sensors also need to be inspected regularly to ensure that smoke sensors can conduct real-time detection of indoor conditions and take timely alarm measures. Before different buildings are officially put into use, it is a very important task to evaluate the performance of their smoke protection and exhaust systems through on-site hot smoke tests without causing damage to the site. The fire scene conditions are simulated by a hot smoke generating device to test whether the smoke detectors meet the standards.
[0003] When the fire detection hot smoke generating device is in use, smoke is usually generated in the device and then brought close to the smoke sensor to check whether the smoke sensor can be used normally. However, since the installation locations of smoke sensors in buildings are very scattered, this will result in the need to constantly move the device to the place where detection is required when detecting the smoke alarm. In addition, in order to protect the surrounding environment during the movement, it is also necessary to extinguish the smoke cake and ignite the smoke cake after the smoke generating device is moved to the appropriate place. This is a waste of time and affects work efficiency.
[0004] After searching Chinese patents, a fire detection hot smoke generating device (publication number CN220237651U) was found, which includes a base plate and a box body. The upper surface of the base plate is fixedly connected to the lower surface of the box body, the lower surface of the base plate is fixedly connected with a universal wheel, the upper surface of the base plate is fixedly connected with a support frame, the side of the support frame is fixedly connected with a handle, a sealing mechanism, the sealing mechanism is arranged on the box body, and is used to control the amount of smoke exhaust in the box body and the smoke exhaust switch, the ventilation mechanism, the ventilation mechanism is arranged in the box body, and is used to control the direction and flow rate of the smoke flow in the box body, and also includes a dust collection mechanism, the dust collection mechanism is arranged on the box body, and is used to collect dust generated by the smoke production in the box body, which solves the problem that in order to protect the surrounding environment from being affected during the movement, the smoke cake needs to be extinguished, and the smoke cake needs to be ignited after the smoke generating device is moved to an appropriate place, which is very time-consuming and affects the work efficiency.
[0005] The above patent facilitates the collection of dust generated by smoke production in the box, but when the smoke cake is burning inside the container, there is only one outlet for ventilation to the outside, resulting in insufficient oxygen inside the container, which will cause incomplete combustion of the smoke cake.
[0006] Therefore, it is necessary to invent a fire detection hot smoke generating device to solve the above problems. Utility Model Content
