Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically to a control handle, system, and application for a bucket-type fire-fighting system for helicopters. Background Technology

[0002] A helicopter fire bucket is a container used to load and spray water or fire extinguishing agents, offering advantages such as high fire extinguishing efficiency, convenient water access, and continuous operation. In existing technology, the bucket's drain valve is typically locked by a lock, which is controlled by a handle. After the helicopter reaches the fire site, manually pressing a button on the handle unlocks the lock, allowing the drain valve to open under water pressure. After spraying water, the lock's wire rope automatically resets under the action of a spring, automatically closing the bucket's drain valve and facilitating subsequent water access. The above-mentioned technologies have the following drawbacks in practical applications: 1. Existing locks cannot control the opening degree of the drain valve, thus making it impossible to control the water spraying speed, resulting in uneven water spraying in different areas. This can easily lead to over-spraying and wasting water resources, or under-spraying and failing to effectively suppress the fire; 2. The control and unlocking of the locks rely on manual operation, which is prone to significant deviations in spraying position due to operational errors. Furthermore, the reaction speed of manual operation is relatively slow, which can delay the optimal spraying time and thus affect the fire extinguishing effect; 3. The current fire extinguishing control system suffers from low intelligence, specifically requiring manual division of fire extinguishing zones, which is not only costly but also... The process involves significant time and manpower constraints, and subjective judgments can lead to unreasonable area divisions. The need for manual prioritization of water-spraying zones is limited by individual experience and understanding, making it difficult to scientifically and accurately assess the urgency of each area. Manually planning water-spraying tasks is also problematic, as it fails to fully consider various complex factors, resulting in inefficient task allocation. Furthermore, the need for manual planning of water-spraying and water-collection routes increases operational complexity and uncertainty. In summary, the entire firefighting operation requires extensive data analysis, which is not only inefficient and prone to errors but also fails to yield optimal firefighting strategies, significantly impacting firefighting effectiveness and resource utilization efficiency.

[0014] In step two above, the control center uses a data collection module to collect data on the size, intensity, topography, and wind direction of the fire, uses an automatic scheduling module to plan the operational area, allocate helicopter water-dropping tasks, and converts the results into instructions sent to the helicopters and control handles. The control handles switch control modes and water-dropping speeds according to the instructions. Specifically, planning the operational area involves using an image recognition algorithm to identify and divide the fire into multiple fire zones, using a priority assessment algorithm to evaluate the threat level of each fire zone, and determining the fire suppression priority accordingly. Allocating helicopter water-dropping tasks involves using an estimation algorithm to estimate the amount of water needed for each fire zone based on its intensity and area, then allocating the operational area based on the fire suppression priority and the helicopter's water capacity, and using a path planning algorithm to plan the optimal water-dropping path based on the helicopter's starting position, water capacity, and water-dropping speed, and the optimal water intake path based on the location, capacity, and water intake speed of the water source, as well as the helicopter's flight speed and water capacity.

[0018] In step six above, the control center uses the remote command module to establish contact with the helicopter and manually intervene in the water spraying mission.

[0020] Preferably, in step three, the control handle operation method is as follows: press and hold the switch button to enter mode selection, press the switch button to switch the control mode and water spraying speed, press the confirmation button to confirm, press and hold the switch button again to exit mode selection, the indicator light unit displays the current mode and water spraying speed by being constantly lit, and indicates the currently selected control mode and water spraying speed by flashing, and after exiting mode selection, the drain valve can be opened by pressing the confirmation button.

[0034] Please see the appendix Figure 8 The present invention provides an embodiment of the application of a bucket-based fire suppression control system for helicopters, comprising the following steps: Step 1, preparation; Step 2, task planning; Step 3, fire suppression; Step 4, real-time monitoring; Step 5, dynamic adjustment; Step 6, manual intervention; Step 7, completion of the fire suppression task.

[0035] In step one above, the bucket body 3 is unfolded, the support frame 33, the first steel cable 34 and the second steel cable 35 are installed, the first steel cable 34 and the second steel cable 35 are connected to the locking device 2, the control handle is connected to the locking device 2, the camera 32 and the control center 4 respectively, the control center 4 is connected to the helicopter, and the locking device 2 is installed on the helicopter by the suspension rope.

[0036] In step two above, the control center 4 uses the data collection module 42 to collect data on the size, intensity, topography, and wind direction of the fire, uses the automatic scheduling module 43 to plan the operational area, allocate helicopter water-dropping tasks, and converts the results into instructions to send to the helicopter and the control handle. The control handle switches the control mode and water-dropping speed according to the instructions. Specifically, planning the operational area involves: using an image recognition algorithm to identify and divide the fire into multiple fire zones; using a priority evaluation algorithm to assess the threat level of the fire zones and determine the fire suppression priority accordingly; allocating helicopter water-dropping tasks involves: using an estimation algorithm to estimate the amount of water required for the fire zones based on the intensity and area of ​​the fire; then allocating the operational area based on the fire suppression priority and the helicopter's water load; and using a path planning algorithm to plan the optimal water-dropping path based on the helicopter's starting position, water load, and water-dropping speed, and to plan the optimal water intake path based on the location, capacity, and water intake speed of the water source, as well as the helicopter's flight speed and water load.

[0037] In step three above, the helicopter collects water according to the water collection path and flies to the work area. Following the spraying path, for helicopters using automatic spraying control, the control handle directly controls the locking device 2 to open the drain valve 31 after the helicopter reaches the spraying position. For helicopters using manual spraying control, the control handle is manually operated after the helicopter reaches the spraying position to control the locking device 2 to open the drain valve 31. Specifically, the control handle operation method is as follows: Press and hold the switch button 192 to enter mode selection; press the switch button 192 to switch the control mode and spraying speed; press the confirmation button 191 to confirm; press and hold the switch button 192 again to exit mode selection. The indicator light unit 18 displays the current mode and spraying speed by being constantly lit and by flashing to indicate the currently selected control mode and spraying speed. After exiting mode selection, pressing the confirmation button 191 will open the drain valve 31.

[0038] In step four above, the control handle and camera 32 send data to the control center 4 in real time, and the real-time monitoring module 44 visualizes the data, which includes the helicopter position, water spray volume and fire zone image.

[0039] In step five above, the automatic scheduling module 43 assesses the fire situation based on the fire zone image and dynamically adjusts the water spraying task.

[0040] In step six above, the control center 4 uses the remote command module 45 to establish contact with the helicopter and manually intervene in the water spraying task.

[0041] In step seven above, steps three through six are repeated until the fire extinguishing task is completed.

[0042] Working principle: When using this invention, the bucket body 3 is unfolded, and the support frame 33, the first steel cable 34, and the second steel cable 35 are installed. The first steel cable 34 is connected to the second mounting hole 212, and the second steel cable 35 is connected to the wire rope 247. The first mounting hole 211 is connected to the helicopter's hoisting rope, the first signal line 14 is connected to the second signal line 2211, and the power line 12 is connected to the power supply through the plug 13. The control center 4 establishes a data connection with the helicopter through the second communication unit 41, and establishes a data connection with the control handle through the second communication unit 41 and the first communication unit 110. The control center 4 uses the data collection module 42 to collect data on the size of the fire, the fire intensity, the terrain, and the wind direction. The automatic scheduling module 43 plans the operational area, assigns water-spraying tasks to helicopters, and converts the results into instructions sent to the helicopters and control handles. The control handles switch control modes and spraying speeds according to the instructions. The operational area planning unit 431 uses an image recognition algorithm to identify and divide the fire scene into multiple fire zones. It uses a priority evaluation algorithm to assess the threat level of the fire zones and determine the fire suppression priority accordingly. The water-spraying task allocation unit 432 estimates the required water volume for each fire zone based on its fire intensity and area using an estimation algorithm. Then, based on the fire suppression priority and the helicopter's water load, it allocates the operational area and uses a path planning algorithm to plan the optimal spraying path based on the helicopter's starting position, water load, and spraying speed. Based on the location, capacity, and water collection speed of the water source, as well as the helicopter's flight speed and water load, an optimal water collection path is planned. The helicopter collects water according to the path and flies to the work area. Following the spraying path, for helicopters using automatic spraying control, the control handle directly controls the locking device 2 to open the drain valve 31 after the helicopter reaches the spraying position. For helicopters using manual spraying control, the control handle is manually operated after the helicopter reaches the spraying position to control the locking device 2 to open the drain valve 31. The specific operation method of the control handle is as follows: Enter mode selection by long-pressing the switch button 192 in the button unit 19; switch control mode and spraying speed by tapping the switch button 192. Confirm by pressing the confirmation button 191, and exit mode selection by pressing and holding the switch button 192 again. The current mode and water spraying speed are displayed by the high flow rate indicator 181, low flow rate indicator 182, automatic mode indicator 183, and manual mode indicator 184 in the indicator unit 18 through constant illumination, and by flashing to indicate the currently selected control mode and water spraying speed. After exiting mode selection, the drain valve 31 can be opened by pressing the confirmation button 191. Specifically, after pressing the confirmation button 191, the electromagnetic push rod 22 is activated. If the current water spraying speed is low, the first electromagnet 228 is activated. If the water spraying speed is high, the first electromagnet 228 and the second electromagnet 229 are activated in sequence.After the first electromagnet 228 is activated, it becomes energized and attracts the push rod body 224. The push rod body 224 drives the connecting rod assembly 23, causing the second locking plate 243 to disengage from the stop block 238. The second locking plate 243 can no longer lock the plug 246. Under the influence of gravity, the wire rope 247 moves the plug 246 downward, sliding it onto the first locking plate 242. One end of the second locking plate 243 deflects into the through groove 245 and then automatically resets under the action of the fourth spring 244. The wire rope 247 drives the winch 27 to rotate on the connecting shaft 272, and the coil spring 271 winds up. At the same time, the first electromagnet 228 is de-energized, and under the action of the first spring 225, the stop plate 226 drives the push rod body 224 to reset. This causes the stop block 238 to reset until the first limit block 223 is limited by the first limit hole 222. After the water is drained, the winch 27 rotates and resets under the action of the coil spring 271, winding up the wire rope 247, causing the plug 246 to move upward and reset. After the first electromagnet 228 and the second electromagnet 229 are activated in sequence, the second electromagnet 229 will attract the first electromagnet 228. The first electromagnet 228 slides inward along the second limit hole 227, compressing the second spring 2210, causing the push rod body 224 to slide further inward, thereby causing the second locking plate 243 and the first locking plate 242 to disengage from the stop block 238, allowing the plug 246 to slide along the fourth housing 24 to the lowest position. At this time, the drain valve 31 opens. At its maximum, after the second electromagnet 229 is de-energized, the first electromagnet 228 automatically resets under the action of the second spring 2210. The movement of the linkage assembly 23 is as follows: the push rod body 224 drives the hollow guide rail 239, which in turn drives the first connecting rod 232 and the second connecting rod 236 via the first connecting member 231. The first connecting rod 232 rotates on the second connecting member 233, causing the third spring 235 to deform. The second connecting rod 236 then drives the third connecting rod 237 to deflect on the cover plate 241, causing the stop block 238 on the third connecting rod 237 to leave the second locking plate 243. After the push rod body 224 extends, it drives the hollow guide rail 239 to reset, causing the first connecting member 231 to drive the first connecting rod 232... 2. The second link 236 is reset. During this process, the third spring 235 provides an auxiliary reset force, and the stop lever 234 limits the final position of the first link 232. During the water spraying task, the control handle and camera 32 send data to the control center 4 in real time. The data storage module 46 stores the data, and the real-time monitoring module 44 visualizes the data. The data includes the helicopter position, water spray volume, and fire zone image. The water spray volume is determined by the water spray volume statistics unit 112 based on the number of sprays. The automatic scheduling module 43 assesses the fire based on the fire zone image and dynamically adjusts the water spraying task. The control center 4 uses the remote command module 45 to establish contact with the helicopter and manually intervene in the water spraying task.The first housing 1 and the grip 11 form the outer shell of the control handle. The main control unit 16 in the circuit module 15 executes control commands, the positioning unit 17 acquires position data, and the power management unit 111 manages the power supply. The second housing 21 forms the outer shell of the locking device 2, and the third housing 221 forms the outer shell of the electromagnetic push rod 22. Three fixing rods 25 are used to fix one third spring 235 and two fourth springs 244, respectively. The guide frame 26 guides the wire rope 247.

The control handle switches the control mode and water-spraying speed according to the instructions. Specifically, planning the operation area involves: using an image recognition algorithm to identify and divide the fire area into multiple fire zones, using a priority evaluation algorithm to assess the threat level of the fire zone, and determining the fire extinguishing priority accordingly. Assigning helicopter water-spraying tasks involves: using an estimation algorithm to estimate the amount of water required for the fire zone based on the intensity and area of ​​the fire zone, then assigning the operation area based on the fire extinguishing priority and the helicopter's water load, and using a path planning algorithm to plan the optimal water-spraying path based on the helicopter's starting position, water load, and water-spraying speed, and planning the optimal water-taking path based on the location, capacity, and water-taking speed of the water source, as well as the helicopter's flight speed and water load.
