Description

Technical Field

[0001] The utility model relates to the technical field of fire protection facility detection, in particular to a temperature sensing detector for detecting building fire protection facilities. Background Art

[0002] Thermal fire detectors mainly use thermistors to detect fires. In the initial stage of a fire, on the one hand, a large amount of smoke is generated, and on the other hand, a large amount of heat is released during the combustion process, causing the ambient temperature to rise sharply. The thermistor in the detector undergoes physical changes, responding to abnormal temperatures, temperature rates, and temperature differences, thereby converting temperature signals into electrical signals and performing alarm processing. When installing thermal fire detectors, in order to ensure that the thermal fire detectors can detect and alarm normally, it is necessary to test the thermal fire detectors;

[0003] Traditional temperature detectors for detecting building fire protection facilities have some shortcomings. Burning objects emit a large amount of smoke, which allows the temperature detector to sense the smoke changes in the environment and issue a smoke alarm. However, the large amount of smoke emitted by burning objects cannot be affected by the external wind direction like a real fire source, resulting in uneven smoke emission, which in turn causes the temperature sensor to trigger the smoke inaccurately.

A shielding frame 713 is fixedly connected to the outer side of the upper end of the sedimentation bin 75 near the docking pipe 76.

[0022] In this embodiment, a cover plate 711 is movably connected to the inner side of the docking groove 74, a handle 712 is fixedly connected to the upper end of the cover plate 711, the docking tube 76 and the sedimentation bin 75 are interconnected, the axis lines of the docking tube 76, the dispersion bin 77 and the baffle 78 are located on the same straight line, the dispersion block 710 is fan-shaped, and there are multiple groups of mounting grooves 79 and dispersion blocks 710.

[0023] Specifically, the burning material is placed inside the burning bin 71, and then the burning material is ignited, and then the handle 712 is held tightly, and the cover plate 711 is inserted into the inner side of the docking groove 74, so that the burning bin 71 forms a closed space, so that the burning material emits a large amount of smoke, and the smoke is allowed to float to the inner side of the connecting pipe 73 through the connecting hole 72, and the smoke is allowed to float to the inner side of the precipitation bin 75, and at the same time, the smoke floats to the inner side of the dispersion bin 77 through the docking pipe 76, so that the baffle 78 disperses the smoke to four groups, and the smoke is dispersed outward through the installation groove 79 and the dispersion block 710, and at the same time, the external air is blown through the shielding frame 713 When the smoke reaches the dispersion bin 77, the smoke will float with the air and float naturally upward, so that the temperature sensor detector body 2 can sense the smoke in the air and then judge the fire situation. The combustible material burns in the inner side of the incineration bin 71 and the smoke floats to the inner side of the sedimentation bin 75, so that the smoke is dispersed outward from the dispersion bin 77, and the external air is blown to the dispersion bin 77 through the shielding frame 713, so as to facilitate the smoke to float naturally upward with the air, and to simulate the smoke emitted by the real fire source floating upward due to the external wind direction, so that the temperature sensor detector body 2 can perform accurate detection.

[0024] In this embodiment, the upper end of the support base 1 is fixedly connected to a support frame 3 near the rear side of the incineration bin 71, the outer side of the support frame 3 is slidably connected to a slide 4, the front end of the slide 4 is fixedly connected to a support plate 5, the lower end of the support plate 5 is fixedly connected to a mounting frame 6, the temperature detector body 2 is installed on the inner side of the mounting frame 6, the inner inner wall of the support frame 3 is fixedly connected to a fixing plate 8, the upper end of the fixing plate 8 is installed with a hydraulic cylinder 9, the upper end of the hydraulic cylinder 9 is installed at the lower end of the slide 4, and the temperature detector body 2 is located above the dispersion bin 77.

[0025] Specifically, by installing the temperature detector body 2 on the inner side of the mounting frame 6, and then starting the hydraulic cylinder 9, the hydraulic cylinder 9 pushes the slide 4 upward, and the slide 4 moves upward along the support frame 3. At the same time, the slide 4 drives the support plate 5 to move upward, so that the temperature detector body 2 moves upward, which can achieve the purpose of simulating the installation of the temperature detector body 2 on the top of the building, thereby facilitating the effective detection of the temperature detector body 2.

Since the inner space of the precipitation bin 75 is large, the smoke stays in the inner side of the precipitation bin 75, so that the impurities in the smoke are precipitated in the inner side of the precipitation bin 75, and at the same time The smoke floats to the inner side of the dispersion bin 77 through the butt joint 76, so that the baffle 78 disperses the smoke to the four groups, and disperses the smoke outward through the mounting groove 79 and the dispersion block 710. At the same time, the external air blows to the dispersion bin 77 through the shielding frame 713, so that the smoke floats with the air and naturally floats upward, so that the temperature sensing detector body 2 can sense the smoke in the air and then judge the fire situation. The combustible material burns in the inner side of the incineration bin 71 and the smoke floats to the inner side of the sedimentation bin 75, so that the smoke is dispersed outward from the dispersion bin 77, and the external air is blown to the dispersion bin 77 through the shielding frame 713, so as to facilitate the smoke to float naturally upward with the air, and to simulate the smoke emitted by the real fire source floating upward due to the external wind direction, so that the temperature sensing detector body 2 can perform accurate detection.
