Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, and in particular to a cabin wind speed alarm device for improving operation safety. Background Art

[0002] As global demand for renewable energy continues to grow, wind power generation, as a key component of clean energy, is becoming increasingly important. Wind turbines, particularly combined power wind turbines, are widely used in wind farms around the world due to their high efficiency and environmental friendliness in converting wind energy into electricity.

[0003] Currently, the nacelle design of some United Power wind turbines doesn't fully consider the need for real-time wind speed monitoring and early warning, especially in remote areas with abundant wind resources, such as mountainous areas and wilderness areas. These areas often suffer from unstable communication signals or patchy coverage. Wind turbine nacelles lack internal wind speed alarms, and traditional wind speed alarms rely on additional anemometers for data collection and measurement, which is costly.

[0004] Operators rely on communication devices like telephones and walkie-talkies to exchange information with station staff to obtain critical data such as wind speed. However, this reliance on external communication is not only inefficient, but also significantly reduces the timeliness and accuracy of information transmission in poor communication conditions. More importantly, if an alarm is not immediately issued when wind speed suddenly increases or changes dramatically, operators may face serious personal safety risks due to their inability to take timely safety measures. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a cabin wind speed alarm device for improving operational safety, aiming to solve at least one of the above-mentioned technical problems.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A cabin wind speed alarm device for improving operational safety includes a wind speed detection module, a first voltmeter, a voltage comparison module, an alarm module and a power supply module arranged in the cabin, the wind speed detection module, the alarm module and the power supply module are all connected to the voltage comparison module, and the first voltmeter is connected to the wind speed detection module.

[0007] The beneficial effect of the present invention is that, by setting up a wind speed detection module in the cabin, it is possible to monitor the wind speed changes around the cabin in real time and accurately, and output the corresponding voltage. The current output voltage value of the wind speed detection module is detected by a first voltmeter, and the voltage value is input into a voltage comparison module. A reference voltage can be set in the voltage comparison module. When the input voltage does not exceed the reference voltage, the normally closed port of the relay is closed; when the input voltage exceeds the reference voltage, the normally open port of the relay is closed, and the alarm module sounds an alarm. The device can realize an abnormal wind speed warning by using the wind speed detection module that comes with the cabin, without the need for an additional anemometer for collection and measurement, thus reducing the alarm cost and realizing an immediate alarm for abnormal wind speed, which helps to avoid safety accidents caused by excessive wind speed.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the alarm module includes an indicator light, which is connected in parallel with the voltage comparison module.

[0010] The beneficial effect of adopting the above further solution is that when the input voltage is higher than the reference voltage, the indicator light flashes, which can significantly enhance the intuitiveness of the alarm signal and thus improve alertness to changes in wind speed.

[0011] Furthermore, the alarm module further includes a buzzer, which is connected in parallel with the voltage comparison module.

[0012] The beneficial effect of adopting this further solution is that it combines an indicator light and a buzzer to achieve a dual audio and visual alarm. When the measured voltage value exceeds the preset reference voltage threshold, not only the indicator light will prompt, but the buzzer will also sound, providing a visual and auditory alarm signal to personnel, improving the reliability and effectiveness of the alarm.

[0013] Furthermore, the wind speed detection module includes a voltage-type anemometer and a current-type anemometer, and the device also includes a current-voltage conversion module, the input end of the current-voltage conversion module is connected to the current-type anemometer, and the output end of the current-voltage conversion module is connected to the voltage comparison module.

[0014] The beneficial effect of adopting this further solution is that the combination of voltage-type and current-type anemometers can cover a wider wind speed measurement range. Different anemometer models may have different measurement ranges and accuracies, improving the overall measurement accuracy and reliability. The simultaneous use of voltage-type and current-type anemometers, along with the current-to-voltage conversion module, effectively creates a redundant design. If one anemometer or module fails, the other will still function normally, ensuring the stability of the overall system operation.

[0015] Furthermore, the device also includes a conversion switch, which is used to connect the voltage-type anemometer or the current-type anemometer through a conversion interface, one input end of the conversion switch is connected to the voltage-type anemometer, the other input end of the conversion switch is connected to the current-voltage conversion module, and the output end of the conversion switch is connected to the voltage comparison module.

[0016] The benefit of this further solution is that the switch allows users to switch measurement sources in real time based on actual needs, allowing for quick switching between a voltage-based anemometer and a current-based anemometer (processed by the current-to-voltage conversion module). This flexibility allows the device to adapt to different measurement scenarios and requirements.

[0017] Furthermore, the power supply module includes a first switch and a power conversion module, the input end of the first switch is connected to the 220V power supply, the output end of the first switch is connected to the power conversion module, the power conversion module is connected to the voltage comparison module, and the power conversion module is used to convert 220V AC power into 24V DC power.

[0018] The beneficial effect of adopting the above further solution is that it converts the high voltage of 220V to the low voltage of 24V, greatly reducing the voltage level in the circuit, reducing safety risks such as electric shock and short circuit, and improving the safety of users when operating and maintaining equipment.

[0019] Furthermore, the power supply module further includes a second voltmeter for detecting the voltage of the power conversion module, and the second voltmeter is connected in parallel with the power conversion module.

[0020] The beneficial effect of adopting the above further solution is that the second voltmeter can monitor the voltage output by the power conversion module in real time, providing the user with instant voltage feedback. This helps the user understand the working status of the power conversion module and ensure that the output voltage is stable within an appropriate range.

[0021] Furthermore, the power supply module further includes a battery pack and a plurality of second switches connected in parallel with the voltage comparison module.

[0022] The beneficial effects of adopting this further solution are: the battery pack acts as a redundant power source, seamlessly taking over power supply duties in the event of a main power outage or failure, ensuring that the voltage comparison module (and possibly other modules connected in parallel) can continue to operate normally. In the event of a system failure, controlling the on / off state of the second switch can conveniently isolate the faulty module or power path, simplifying troubleshooting. Furthermore, as an independent power supply unit, the battery pack also facilitates independent maintenance and testing. When battery replacement or other maintenance work is required, closing the corresponding second switch ensures electrical safety during maintenance and simplifies the replacement process.

[0023] Furthermore, a third switch is connected between the power supply module and the voltage comparison module.

[0024] The beneficial effect of adopting this further solution is that the third switch allows the user to independently control the power supply from the power module to the voltage comparison module. This independent control mechanism allows the user to disconnect the power supply to the voltage comparison module when it is not needed, thereby reducing energy consumption and extending the service life of the entire device. If the voltage comparison module fails, closing the third switch isolates the faulty module from the power module, preventing the fault from spreading and affecting other circuit modules, thereby improving device safety.

[0025] Furthermore, the cabin wind speed alarm device is installed in a portable box, and the device is powered by connecting to a 220V power supply in a cabin control cabinet.

[0026] The advantages of adopting this further solution are: the portable case design makes the entire device easy to carry and move, facilitating rapid deployment and transfer between different cabins or locations. By connecting to the 220V power supply in the cabin control cabinet, the device can be flexibly installed in any suitable location within the cabin without requiring additional power wiring or modification. This reduces installation difficulty and cost, while improving installation efficiency. Furthermore, the portable case provides physical protection for the device, preventing it from being directly affected by the external environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] like Figure 1As shown, a cabin wind speed alarm device for improving operational safety includes a wind speed detection module 1, a first voltmeter 2, a voltage comparison module 3, an alarm module 4 and a power supply module 5 arranged in the cabin, the wind speed detection module 1, the alarm module 4 and the power supply module 5 are all connected to the voltage comparison module 3, and the first voltmeter 2 is connected to the wind speed detection module 1.

[0032] Among them, the wind speed detection module 1 is used to detect the wind speed outside the cabin in real time and convert the wind speed signal into an electrical signal; the first voltmeter 2 is used to display the voltage value output by the wind speed detection module 1, thereby indirectly reflecting the magnitude of the wind speed; the voltage comparison module 3 is used to receive the voltage value and compare the voltage value with a preset reference voltage threshold. When the voltage value corresponding to the detected wind speed exceeds the preset threshold, the voltage comparison module 3 outputs a trigger signal; the alarm module 4 is used to receive the trigger signal and activate the alarm according to the trigger signal.

[0033] By setting up a wind speed detection module 1 in the cabin, it is possible to monitor the wind speed changes around the cabin in real time and accurately, and output the corresponding voltage. The current output voltage value of the wind speed detection module 1 is detected by a first voltmeter 2, and the voltage value is input into a voltage comparison module 3. A reference voltage can be set in the voltage comparison module 3. When the input voltage does not exceed the reference voltage, the normally closed port of the relay is closed; when the input voltage exceeds the reference voltage, the normally open port of the relay is closed, and the alarm module 4 sounds an alarm. This device can realize an abnormal wind speed warning using the wind speed detection module 1 that comes with the cabin, without the need for an additional anemometer for collection and measurement, reducing the alarm cost, realizing an immediate alarm for abnormal wind speed, and helping to avoid safety accidents caused by excessive wind speed.

[0034] In the embodiment of the present application, the voltage comparison module 3 is an LM393 voltage comparison module 3 , and when its reference value is set to 1.6V, it represents that the wind speed threshold is 8m / s.

[0035] Optionally, the cabin wind speed alarm device is housed in a portable enclosure, which connects to the 220V power supply in the cabin control cabinet to power each module. This portable enclosure design makes the entire device easily portable and mobile, facilitating rapid deployment and transfer between different cabins or locations. Connecting to the 220V power supply in the cabin control cabinet allows the device to be flexibly installed in any suitable location within the cabin. Furthermore, the portable enclosure provides physical protection for the device, preventing it from being directly affected by the external environment.

[0036] Optionally, the alarm module 4 includes an indicator light 41 and a buzzer 42, both of which are connected in parallel with the voltage comparison module 3. When the voltage value input to the voltage comparison module 3 does not exceed a preset reference voltage threshold, the indicator light 41 is constantly on, indicating that the current wind speed is within a safe range. When the voltage value obtained by the voltage comparison module 3 exceeds a preset reference voltage threshold, the buzzer 42 is energized, indicating that the current wind speed exceeds a safe range.

[0037] Optionally, the wind speed detection module 1 includes a voltage-type anemometer 11 and a current-type anemometer 12. The voltage-type anemometer 11 is directly connected to the voltage comparison module 3. The current-type anemometer 12 is connected to a current-voltage conversion module 13. The input end of the current-voltage conversion module 13 is connected to the current-type anemometer 12, and the output end of the current-voltage conversion module 13 is connected to the voltage comparison module 3.

[0038] In this embodiment of the present application, by calculating the relationship between the output voltage of the voltage-type anemometer 11 and the wind speed, the wind speed comparison is converted to a voltage comparison. For a 0-10V / 0-50m / s anemometer, the current wind speed value can be obtained by multiplying the current voltage value by 5. For a 0-10V / 0-50m / s anemometer, the current-to-voltage conversion module 13 can convert the 4-20mA current output by the anemometer into a 0-10V voltage for detecting the current wind speed value of the current-type anemometer 12.

[0039] Furthermore, the cabin wind speed alarm device also includes a conversion switch 6, which is connected to the voltage-type anemometer 11 or the current-type anemometer 12 through a conversion interface. One input end of the conversion switch 6 is connected to the voltage-type anemometer 11, the other input end of the conversion switch 6 is connected to the current-voltage conversion module 13, and the output end of the conversion switch 6 is connected to the voltage comparison module 3. The conversion switch 6 allows the user to switch the measurement source in real time according to actual needs, that is, to quickly switch between the voltage-type anemometer 11 and the current-type anemometer 12. Due to the different measurement accuracy of the voltage-type anemometer 11 and the current-type anemometer 12, the device can adapt to different measurement scenarios and needs.

[0040] Optionally, the power module 5 includes a first switch 51, a power conversion module 52, a second voltmeter 53, a battery pack 54, and multiple second switches 55. The input end of the first switch 51 is connected to a 220V power supply, the output end of the first switch 51 is connected to the power conversion module 52, and the second voltmeter 53 is connected in parallel with the power conversion module 52. The second voltmeter 53 is used to detect the voltage of the power conversion module 52. The battery pack 54 and the multiple second switches 55 are connected in parallel to the voltage comparison module 3. In the embodiment of the present application, two second switches 55 are provided, and both second switches 55 are connected in series with the battery pack 54. The battery pack 54 serves as a redundant power supply and seamlessly takes over the power supply task when the main power supply is interrupted or fails, ensuring that the voltage comparison module 3 and other modules can continue to operate normally.

[0041] A third switch 7 is also connected between the power supply module 5 and the voltage comparison module 3. The third switch 7 allows the user to independently control the power supply from the power supply module 5 to the voltage comparison module 3. This independent control mechanism allows the user to cut off the power supply to the voltage comparison module 3 when it is not needed, thereby reducing energy consumption and extending the service life of the entire device.

[0042] When the cabin wind speed alarm device fails, the faulty module or power supply channel can be isolated by controlling the switch states of the first switch 51, the second switch 55 and the third switch 7, thereby simplifying the fault troubleshooting process and improving the safety of the device.

[0043] The present invention provides a cabin wind speed alarm device for improving operational safety. The device can be installed in a portable case and connected to a 220V power outlet in the cabin control cabinet. A power module 5 converts the 220V power supply into a 24V power supply, thereby powering the various modules of the device. A first voltmeter 2 measures the voltage output by the anemometer. For a voltage-type anemometer 11, the signal line of the voltage-type anemometer 11 is connected to the input port of a voltage comparison module 3. For a current-type anemometer 12, the signal line of the current-type anemometer 12 is connected to a current-voltage conversion module 13, which converts the current signal into a voltage signal.

[0044] By comparing the voltage value of the voltage comparison module 3 with the preset reference voltage threshold, when the input voltage value exceeds the preset reference voltage threshold, the alarm module 4 will sound an alarm, thus realizing an abnormal wind speed warning.
