Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0043] The tower barrel generally refers to the tower part of a wind turbine generator, which is an important structure for supporting the entire wind turbine generator. As a connecting component between the wind turbine generator set and the foundation ring, the tower barrel can bear the gravity loads of the upper nacelle, hub, blades, etc., the vibration loads caused by the wind wheel, and the environmental wind loads, and is an important component required to realize functions such as maintenance and power transmission and transformation of the wind turbine generator set.

[0044] Currently, the internal structure of the tower barrel consists of a main shaft, a generator, a frequency converter, and a lubrication system. To ensure the safe operation of the wind turbine generator set, a series of safety protection measures are also taken inside the tower barrel, including a lightning protection device equipped in the tower barrel to protect the wind turbine generator set from the influence of lightning strikes, and an inclination monitoring device arranged inside the tower barrel to monitor the verticality inside the tower barrel, timely detect the inclination or displacement of the tower barrel, and prevent structural instability.

[0045] However, using this traditional fire extinguishing device for the wind turbine tower barrel does not have an automatic fire extinguishing function, cannot accurately extinguish the ignitable materials inside the tower barrel, and has relatively high potential safety hazards.

[0046] To this end, the present application provides a fire extinguishing device for a wind turbine tower barrel and a wind power generation unit. By using a detection component to detect the temperature inside the tower barrel to detect signs of fire, when the detection component detects signs of fire inside the accommodation cavity, the controller controls the monitoring component to open to confirm whether there is a fire inside the tower barrel. When it is confirmed according to the image collected by the monitoring component that there is a fire, the controller controls the fire extinguisher to move towards the fire starting position to accurately extinguish the fire starting material. After the fire extinguishing is completed, the fire extinguisher moves to the initial position. Compared with the traditional fire extinguishing device for a wind turbine tower barrel, this structure has an automatic fire extinguishing function and can accurately extinguish the fire starting material inside the tower barrel.

[0047] The following further elaborates on a fire extinguishing device for a wind turbine tower barrel in this embodiment.

[0048] Figure 1 It is a schematic internal structure diagram of a fire extinguishing device for a wind turbine tower barrel provided by an embodiment of the present application; Figure 2 It is a schematic structure diagram of a fire extinguisher in a fire extinguishing device for a wind turbine tower barrel provided by an embodiment of the present application.

[0049] As Figure 1 shown, an embodiment of the present application provides a fire extinguishing device 10 for a wind turbine tower barrel, including a tower barrel body 100 and an automatic fire extinguishing component 200; the tower barrel body 100 has an accommodation cavity 110; the automatic fire extinguishing component 200 is arranged inside the accommodation cavity 110, and the automatic fire extinguishing component 200 includes a detection component 210, a controller 220, a monitoring component 240, and a fire extinguisher 230; the detection component 210 and the fire extinguisher 230 are respectively signal-connected to the controller 220, the detection component 210 is configured to detect the temperature inside the accommodation cavity 110, and the controller 220 is configured to control the opening and closing of the fire extinguisher 230 according to the temperature detected by the detection component 210; the fire extinguisher 230 is movably arranged on the cavity wall of the accommodation cavity 110 to move the fire extinguisher 230 to a first position or a second position; when the fire extinguisher 230 is in the first position, the fire extinguisher 230 faces the fire starting material and extinguishes the fire starting material; when the fire extinguisher 230 is in the second position, the fire extinguisher 230 stops extinguishing the fire.

[0050] Among them, when the detection component 210 detects fire information, the controller 220 controls the monitoring component 240 to open and controls the fire extinguisher 230 to move along the circumference or the axis of the accommodation cavity 110, so that the fire extinguisher 230 moves near the fire starting point and faces the fire starting material for fire extinguishing operation. At this time, the fire extinguisher 230 is in the second position; when the detection component 210 detects that the environmental temperature is within a preset threshold range and the monitoring component 240 detects that the flame at the fire starting point inside the accommodation cavity 110 is extinguished, the controller 220 controls the fire extinguisher 230 to return to the initial position. At this time, the fire extinguisher 230 is in the first position.

[0051] Among them, a complex electrical and electronic system is provided inside the tower barrel structure. The cables inside the tower barrel may short-circuit due to insulation aging, wear, or improper installation, or the electrical equipment may overheat under high-load operation, thus triggering a fire. In the embodiment of the present application, the fire extinguisher 230 is arranged above the electrical equipment with potential safety hazards. In this way, after a fire breaks out, the fire extinguishing distance can be shortened, the fire can be effectively controlled, and the spread of the fire can be prevented.

[0052] Among them, as an optional implementation manner, the fire extinguisher 230 uses a carbon dioxide fire extinguisher. The purpose of such a setting is to quickly reduce the oxygen concentration around the fire source, thereby extinguishing the flame, and carbon dioxide is non-conductive, which makes the carbon dioxide fire extinguisher very safe when extinguishing the burning material and will not cause secondary disasters such as electric shock or short circuit.

[0053] Among them, a plurality of ventilation openings are further provided on the cavity wall of the accommodating cavity 110. Openable and closable windows are provided at the plurality of ventilation openings to prevent overheating of the electrical equipment caused by poor ventilation inside the accommodating cavity 110 and ineffective heat dissipation, thereby increasing the fire risk.

The controller 220 makes necessary adjustments according to the feedback signal.

[0056] Among them, after the controller 220 receives a fixing instruction, the controller 220 drives the electromagnet to fix the fire extinguisher 230 with the elastic buckle. When the controller 220 receives a release instruction, the controller 220 disconnects the power supply of the electromagnet, so that the elastic buckle releases the fire extinguisher 230, and the fire extinguisher 230 can be moved. Specifically, the elastic buckle is made of spring steel and has a certain elastic deformation ability.

[0057] In some embodiments, the accommodating cavity 110 further includes a telescopic member 111.

[0066] Detection members 210 and fire extinguishers 230 are movably arranged on the cavity walls of the respective sub-cavities 113, which can provide multi-layer protection for the inside of the tower barrel to improve the overall safety of the inside of the tower barrel.

[0067] Among them, the types of the detection component 210 include but are not limited to temperature detectors, smoke detectors, gas detectors, etc. The detection component 210 is electrically connected to the alarm. When the value detected by the detection component 210 is greater than or equal to the preset threshold, the detection component 210 triggers an alarm.

[0068] Among them, a partition member 114 is further provided in each sub-cavity 113, and maintenance personnel can perform maintenance on the electrical equipment inside the partition member 114.

[0069] In some embodiments, a chain is further provided below the slide rail. The chain extends along the circumferential direction of the slide rail.

[0073] Among them, the monitoring component 240 selects high-temperature-resistant materials, which can enable the monitoring component 240 to serve in a high-temperature environment for a long time, improving the performance and reliability of the monitoring component 240.

[0074] In some embodiments, the automatic fire extinguishing assembly 200 further includes a plurality of light sources 250, and the plurality of light sources 250 are evenly arranged on the cavity wall of the accommodating cavity 110.

[0075] Among them, the purpose of arranging a plurality of light sources 250 inside the tower barrel is that it can help the staff clearly see the internal structure of the tower barrel, prevent accidents such as slipping or collision, and in case of emergencies, such as fires or equipment failures, good lighting can help personnel evacuate quickly and safely.
