Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire alarms, and in particular to a fire alarm for a cabin of a wind turbine generator set. Background Art
[0002] Fire warning devices, also commonly known as fire alarms, are devices designed to emit sound and light signals by monitoring fire-related factors such as smoke and temperature when a fire occurs. The main function of this device is to issue immediate warnings in the early stages of a fire so that people can quickly take countermeasures, such as evacuating or using fire extinguishers, thereby reducing casualties and property losses.
[0003] With reference to the utility model patent with authorized publication number CN219061904U, a fire alarm device for a wind turbine cabin is disclosed, including an installation fixing connecting plate, an installation bolt hole, a fire alarm support box, an exhaust assembly for a wind turbine cabin and a fire alarm device assembly. The exhaust assembly for the wind turbine cabin includes a dustproof ventilation net, a top ventilation net, a ring plate connecting plate, a support ring plate, a motor connecting shaft, an exhaust motor, a rotating exhaust transmission shaft and a rotating exhaust fan blade. The fire alarm device assembly includes a smoke sensor controller, a connecting support ring, a buckle fixing block, a connecting fixing buckle, a rotating motor, an alarm light rotating shaft and a luminous buzzer alarm light.
[0004] The components provided in the above patent can only sound an alarm in the wind turbine cabin, and the core component, the smoke sensor controller, can only judge the concentration of the smoke. When the smoke concentration reaches a certain concentration, it judges it as a fire and then sounds an alarm. The actual operation conditions in the wind turbine cabin cannot be observed, and sometimes misjudgment may occur. This is also a technical drawback of the existing smoke alarm system. For this reason, we propose a wind turbine cabin fire alarm to solve the above shortcomings. Utility Model Content

[0015] In the utility model, a fire warning device for a cabin of a wind turbine is provided with a smoke alarm on the upper side of the wind turbine. When a fire in the wind turbine causes smoke, the smoke alarm senses it and determines that there may be a fire. At this time, the electric motor in the monitoring mechanism drives the roller to rotate in the track groove, thereby causing the arc plate to rotate around the ring, so that the infrared temperature probe and the camera on the arc plate follow the trajectory of the ring for 360° rotation monitoring.

When the surface temperature of the wind turbine is too high, the infrared temperature probe can feedback the working state of the high temperature overload of the wind turbine in advance, and the camera can directly provide the monitoring picture on the spot, which is provided to the staff of the wind power fire control center for observation and judgment. The utility model uses the infrared temperature probe and the camera in the monitoring mechanism to cooperate with the smoke alarm to comprehensively monitor the working state of the wind turbine, so as to avoid the misjudgment of the smoke alarm. At the same time, the infrared temperature probe can feedback the working state of the high temperature overload of the wind turbine in advance to prevent the wind turbine from being overloaded and burned. In addition, the camera can directly provide the monitoring picture on the spot, which is convenient for comprehensively judging the operating state of the wind turbine.

[0024] In this embodiment, the monitoring mechanism 8 includes an arc plate 81, a flat seat 82 is provided at the bottom of the arc plate 81, an infrared temperature measuring probe 83 and a camera 84 are installed on the flat seat 82, first side supports 85 are symmetrically provided on both sides of the arc plate 81, an electric motor 86 is fixedly installed on the outer side of the first side support 85, the output end of the electric motor 86 rotates to pass through the inner side of the first side support 85 and a roller 87 is fixedly installed on the output end of the electric motor 86, and the roller 87 is slidably engaged with the inner side of the rail groove 72.
[0025] By setting up in the above manner, starting the electric motor 86 can drive the inner roller 87 to rotate, and the roller 87 rotates inside the track groove 72, thereby driving the arc plate 81 and the infrared temperature measuring probe 83 and camera 84 on the arc plate 81 to rotate around the track groove 72, thereby realizing the 360° no-blind-angle monitoring capability of the infrared temperature measuring probe 83 and camera 84.
[0026] In this embodiment, the smoke alarm 6 is located directly above the wind turbine generator set 3 .
[0027] By means of the above arrangement, when smoke is generated in the wind turbine set 3, the smoke alarm 6 can receive the smoke signal relatively quickly.
[0028] In this embodiment, the distance between the two inner mounting seats 73 is slightly greater than the thickness of the mounting plate 5 .
[0029] By the above arrangement, the distance between the two inner mounting seats 73 is slightly larger than the thickness of the mounting plate 5, so that when the ring 71 is installed, it is convenient to slide and push the inner mounting seat 73 from the side of the mounting plate 5. After the inner mounting seat 73 is fixedly installed, the smoke alarm 6 can be installed.
[0030] In this embodiment, the flat seat 82 is screwed and installed on the outer side of the arc plate 81 , and the first side support 85 is screwed and installed on the side of the arc plate 81 .
[0031] Through the above-mentioned arrangement, the screw connection design of the flat seat 82 and the first side support 85 facilitates the subsequent disassembly and maintenance work.
[0032] In this embodiment, the arc plate 81 is symmetrically and fixedly mounted with second side supports 88 , and a roller 89 is rotatably mounted between the two second side supports 88 .
[0033] By the above-mentioned arrangement, the roller 89 is arranged so that when the roller 87 rotates inside the track groove 72, the arc plate 81 is driven to rotate around the ring 71.

[0034] The working principle of a wind turbine cabin fire warning device provided by the utility model is as follows:
[0035] When in use, the smoke alarm 6 remains in the on state. When smoke is generated in the wind turbine 3 and the smoke floats upward to the smoke alarm 6, the smoke alarm 6 detects the smoke signal. At this time, the electric motor 86 starts immediately, driving the roller 87 at the gas inner measuring end to rotate, and then driving the entire arc plate 81 to rotate around the outer side of the ring 71, so that the infrared temperature measuring probe 83 and the camera 84 on the arc plate 81 can perform 360° no-dead-angle monitoring. The infrared temperature measuring probe 83 monitors the location where the smoke occurs and determines the temperature information. The camera 84 feeds back the real-time monitoring picture of the scene to the wind power fire control center, and the staff of the wind power fire control center comprehensively judges the situation on the scene. Under normal daily working conditions, the electric motor 86 is in intermittent drive rotation, driving the infrared temperature measuring probe 83 and the camera 84 to perform intermittent cruise monitoring. The infrared temperature measuring probe can feedback the high-temperature overload working state of the wind turbine 3 in advance to prevent the wind turbine from overload and burning.
[0036] Compared with the related art, the wind turbine cabin fire warning device provided by the utility model has the following beneficial effects:
[0037] The utility model provides a wind turbine cabin fire warning device. The infrared temperature probe 83 and camera 84 in the monitoring mechanism arranged in the utility model cooperate with the smoke alarm 6 to comprehensively monitor the working status of the wind turbine 3 to avoid misjudgment of the smoke alarm 6.
