[0029] 101 - First smoke detector; 102 - Second smoke detector; 103 - Fire alarm controller; 104 - Alarm device; 105 - Gas fire extinguishing device; 106 - Monitoring module Detailed Implementation Manner

[0030] The following will describe in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0031] As described in the background art, in the related art, the fire hazard caused by the damage of the filter capacitor in the tower base control cabinet cannot be detected in time, which easily leads to the burning of more equipment components and causes serious losses.

[0032] In view of this, the embodiments of the present disclosure provide a smoke alarm system for a wind turbine, which can timely detect the fire hazard of the filter capacitor in the tower base control cabinet and perform alarm processing, thereby improving the safety of the unit operation.

[0033] Figure 1 It is a schematic diagram of a smoke alarm system for a wind turbine shown according to an exemplary embodiment. Refer to Figure 1 , the smoke alarm system includes a first smoke detector 101, a second smoke detector 102, a fire alarm controller 103, and an alarm device 104. The first smoke detector 101 and the second smoke detector 102 are both communicatively connected to the fire alarm controller 103, and the fire alarm controller 103 is communicatively connected to the alarm device 104.

[0034] It should be understood that according to the results detected by the first smoke detector 101 and the second smoke detector 102 respectively, their respective alarm signals can be transmitted to the fire alarm controller 103. After receiving the signals from the smoke detectors, the fire alarm controller 103 can trigger the alarm device 104 to give an alarm prompt to notify relevant personnel to take necessary measures in time.

[0035] Exemplarily, the first smoke detector 101 and the second smoke detector 102 are both communicatively connected to the fire alarm controller 103. Specifically, the cable lines between the tower base grid connection cabinet and the tower base control cabinet can be arranged and wired. That is to say, the signal line of the first smoke detector 101 can be incorporated into the line of the second smoke detector 102 in the tower base grid connection cabinet. Thus, the fire alarm controller 103 can collect the smoke alarm signals in the tower base control cabinet while collecting the smoke alarm signals of the tower base grid connection cabinet, reducing the layout chaos of the cable lines and helping to improve the overall efficiency of wiring, thereby improving the reliability and comprehensiveness of smoke alarm.

[0036] Exemplarily, unique address codes can be assigned to each smoke detector through preset programming settings, and an address mapping table can be set in the fire alarm controller to associate each address code with the corresponding smoke detector. When a certain smoke detector alarms, the corresponding address code can be transmitted to the alarm controller through the signal line. The controller can identify the source of the alarm signal based on the received address information, thereby improving the reliability of alarm processing.

[0037] The first smoke detector 101 is arranged above the filter capacitor in the tower base control cabinet for detecting the fire situation of the filter capacitor.

[0038] It should be understood that the tower base control cabinet is used to control the operation and regulation of the wind turbine generator set, including the control and monitoring of equipment such as the fan, converter, and generator. The filter capacitor is a commonly used component in electrical equipment and can be used to filter the power signal to ensure stable voltage and current in the circuit. Since the filter capacitor generates a certain amount of heat during operation and the internal dielectric of the capacitor fails due to capacitor aging or damage, resulting in internal short circuit or breakdown of the capacitor, there is a certain degree of fire risk.

[0039] It should also be understood that if the filter capacitor catches fire, the smoke detector can quickly detect the smoke and give an alarm in time, effectively avoiding the occurrence of fire accidents and protecting the safety of equipment and personnel. Therefore, arranging the first smoke detector 101 above the filter capacitor can improve the detection sensitivity to the fire situation of the filter capacitor and ensure the safe and reliable operation of the equipment.

[0040] The second smoke detector 102 is arranged at a preset position in the tower base grid connection cabinet.

[0041] It should be understood that the tower base grid connection cabinet is used to connect the electric energy generated by the wind turbine generator set and send it into the power grid, and at the same time, it also plays a role in monitoring and protecting the wind turbine generator set. By installing a smoke detector at a preset position in the tower base grid connection cabinet, early detection and alarm of fire can be realized, ensuring the safe and stable operation of the equipment.

[0042] Both the fire alarm controller 103 and the alarm device 104 are arranged inside the tower base of the wind turbine generator set.

[0043] Exemplarily, the specific installation positions of the second smoke detector 102, the fire alarm controller 103 and the alarm device 104 can be determined according to the actual situation, in combination with the fire safety code and the requirements of the equipment layout. The embodiments of the present disclosure do not limit this.

[0044] In one embodiment, the alarm device 104 can be an audible and visual alarm.

[0045] It should be understood that the audible and visual alarm can include a buzzer and an alarm indicator light. When receiving the alarm signal sent by the fire alarm controller, it can trigger the buzzer to emit an alarm sound and at the same time trigger the flash lamp to flash for alarm indication.

[0046] Exemplarily, the sound emitted by the buzzer can be different types of sounds, such as electric bell sounds, alarm sounds, music sounds, etc., and the alarm indicator light can be set with different colors of lights according to requirements, such as red lights, yellow lights, blue lights, etc. The embodiments of the present disclosure do not limit this.

[0047] In one embodiment, as Figure 2 shown, the smoke alarm system can include a gas fire extinguishing device 105;

[0048] The gas fire extinguishing device 105 is arranged in the preset areas of the tower base control cabinet and the tower base grid connection cabinet;

[0049] The gas fire extinguishing device 105 is communicatively connected to the fire alarm controller 103.

[0050] It should be understood that the gas fire extinguishing device 105 can be used as a fire extinguishing means and is connected to the fire alarm controller 103 through a communication networking cable to trigger the activation of the fire extinguishing device in case of a fire. And arranging the gas fire extinguishing device 105 in the preset areas of the tower base control cabinet and the tower base grid connection cabinet can ensure timely fire extinguishing in case of a fire and prevent the spread of the fire from causing greater losses.

[0051] Exemplarily, the gas fire extinguishing device 105 can use fire extinguishing media such as carbon dioxide and heptafluoropropane, and can be arranged in the preset areas of the tower base control cabinet and the tower base grid connection cabinet in a suspended or fire detection tube type. The embodiments of the present disclosure do not limit this.

[0052] In one embodiment, the fire alarm controller 103 can include a display module for displaying alarm information. Among them, the display module can be an LED (light-emitting diode) display screen.

[0053] It should be understood that the LED display screen displays various information by controlling semiconductor light-emitting diodes. In the embodiments of the present disclosure, when the fire alarm controller 103 receives an alarm signal sent by the smoke detector, the relevant alarm information can be displayed on the LED display screen to achieve the effect of timely alarm.

[0054] Exemplarily, the content, pixel pitch, brightness, color, etc. of the LED display screen can be set according to the actual situation, and the embodiments of the present disclosure do not limit this.

[0055] In one embodiment, the first smoke detector 101 and the second smoke detector 102 can be relay-type smoke detectors or optoelectronic smoke detectors.

[0056] It should be understood that the relay-type smoke detector can detect and alarm smoke through an electromagnetic relay; while the optoelectronic smoke detector can use an optoelectronic sensor to detect the concentration of smoke particles in the air, and trigger an alarm when the concentration exceeds the set threshold. The signal line and power line of the smoke detector can be connected to the corresponding positions in the circuit for use according to the actual situation.

[0057] In one embodiment, as Figure 3 shown, the smoke alarm system can further include a monitoring module 106;

[0058] The monitoring module 106 is arranged inside the tower base of the wind turbine generator;

[0059] The monitoring module 106 is communicatively connected to the fire alarm controller 103.

[0060] Among them, the monitoring module 106 can be an infrared detector.

[0061] It should be understood that the infrared detector can judge the presence of a fire by detecting thermal radiation. When the tower base control cabinet or the tower base grid connection cabinet catches fire, the fire will generate infrared radiation. At this time, the infrared detector can detect this radiation, then convert it into an electrical signal, and then send a fire alarm signal to the fire alarm controller 103, so as to achieve the effect of timely alarm.

[0062] Exemplarily, the specific installation position of the monitoring module 106 can be determined according to the actual situation, in combination with fire safety specifications and equipment layout requirements, and the embodiments of the present disclosure do not limit this.

[0063] In one embodiment, the smoke alarm system can further include a communication module, and the fire alarm controller 103 sends alarm information to the booster station through the communication module.

[0064] It should be understood that the step-up substation is the central monitoring site of the wind farm, which collects the operation data and status information of each wind turbine. By transmitting the alarm information to the step-up substation, the fire situation of the entire wind farm can be uniformly monitored and responded to in the central control room. Specifically, the staff in the step-up substation can remotely understand the fire situation inside the tower base through the alarm information reported in a timely manner by the automatic fire protection device software, and take corresponding emergency measures according to the situation. And transmitting the alarm information to the step-up substation can be recorded and archived in the central control system, and these data can be used for post-event analysis of the fire cause to formulate more perfect preventive measures.

[0065] In one embodiment, the communication module can be a communication module capable of communicating through the Zigbee wireless communication protocol or the LoRa wireless communication protocol.

[0066] It should be understood that the Zigbee wireless communication protocol or the LoRa wireless communication protocol can be used for the communication between the alarm controller and the step-up substation, which is suitable for low-power and low-bandwidth long-distance wireless communication. In remote areas or places with poor signal coverage, a stable connection can also be maintained. In addition, considering the communication requirements of the alarm controller and the step-up substation and the characteristics of the communication environment, a suitable wireless protocol can be selected to achieve a stable communication connection between the two, ensuring the timely transmission of alarm information and the execution of control instructions.
