Description

Technical Field

[0001] The present invention relates to the technical field of fire fighting equipment, and in particular to a bucket water sprinkler fire extinguishing control handle, system and application for a helicopter. Background Art

[0002] The helicopter fire bucket is a container for loading and spraying water or fire extinguishing agents, which has the advantages of efficient fire extinguishing, convenient water collection, and continuous operation. In the prior art, the water discharge valve of the bucket is generally locked by a lock head, which is controlled by a control handle. After the helicopter reaches the fire scene, the lock head can be unlocked by manually pressing the button of the control handle, so that the water discharge valve is opened under the action of water pressure. When the water spraying is completed, the steel wire rope of the lock head is automatically reset under the action of the coil spring, so that the water discharge valve of the bucket is automatically closed, so as to facilitate the subsequent water collection operation. The above technology has the following disadvantages in practical application: 1. The existing lock cannot control the opening degree of the drain valve, so it cannot control the water sprinkling speed, resulting in uneven regional water sprinkling, which is prone to excessive water sprinkling resulting in water resource waste, or insufficient water sprinkling resulting in ineffective fire suppression; 2. The control and unlocking of the lock relies on manual operation, which is prone to large deviations in the water sprinkling position due to operational errors, and the response speed of manual operation is relatively slow, which is prone to delay the best time for water sprinkling, thereby affecting the fire extinguishing effect; 3. The fire extinguishing control system currently has the problem of low intelligence, which is specifically manifested in the need to manually divide the fire extinguishing area, which is not only time-consuming but also labor-intensive. It not only wastes a lot of time and manpower, but may also lead to unreasonable regional division due to inaccurate subjective judgment; it is necessary to manually determine the priority of the watering fire extinguishing area, which is easily limited by personal experience and cognition, and it is difficult to scientifically and accurately assess the urgency of each area; it is necessary to manually formulate watering tasks, which is difficult to fully consider various complex factors, making task allocation inefficient; it is necessary to manually plan the watering route and water intake route, which increases the complexity and uncertainty of the operation; in summary, a large amount of data analysis is required during the entire fire-fighting operation, which is not only inefficient and prone to errors, but also unable to obtain the optimal fire-fighting strategy, greatly affecting the fire-fighting effect and resource utilization efficiency.

The watering task allocation unit 432 estimates the amount of water required for the fire zone according to the fire intensity and area of ​​the fire zone using the estimation algorithm, and then allocates the operation area based on the fire extinguishing priority and the water carrying capacity of the helicopter, and uses the path planning algorithm to plan the optimal watering path planning according to the starting position, water carrying capacity and watering speed of the helicopter. , according to the location, capacity and water intake speed of the water source, as well as the flight speed and water carrying capacity of the helicopter, the optimal water intake path is planned; the helicopter completes water intake according to the water intake path and flies to the operation area, and flies according to the water sprinkling path. For helicopters that use automatic water sprinkling control, the control handle directly controls the locking device 2 to open the drain valve 31 after the helicopter reaches the water sprinkling position. For helicopters that use manual water sprinkling control, after the helicopter flies to the water sprinkling position, the control handle is manually operated to control the locking device 2 to open the drain valve 31. The specific operation method of the control handle is: enter the mode selection by long pressing the switch button 192 in the button unit 19, and switch the control mode and water sprinkling speed by clicking the switch button 192. The confirmation button 191 is clicked to confirm, and the mode selection is exited by long pressing the switch button 192 again. The large flow indicator light 181, the small flow indicator light 182, the automatic mode indicator light 183, and the manual mode indicator light 184 in the indicator light unit 18 display the current mode and the watering speed by being always on, and the currently selected control mode and watering speed are indicated by flashing. After exiting the mode selection, the drain valve 31 can be controlled to open by clicking the confirmation button 191. Specifically, after clicking the confirmation button 191, the electromagnetic push rod 22 is started. If the current watering is low speed, the first electromagnet 228 is started. If the watering is high speed, the first electromagnet 228 and the second electromagnet 229 are started in sequence.After the first electromagnet 228 is started, the first electromagnet 228 will be electrically attracted to the push rod body 224, and the push rod body 224 drives the connecting rod assembly 23, so that the second lock plate 243 disengages from the block 238, and the second lock plate 243 cannot lock the plug 246. Under the action of the gravity of the water, the wire rope 247 drives the plug 246 to move downward and slide onto the first lock plate 242. One end of the second lock 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 winding spring 271 is wound. At the same time, the first electromagnet 228 loses power. Under the action of the first spring 225, the baffle 226 drives the push rod body 224 to reset , so that the block 238 is reset until the first limit block 223 is limited by the first limit hole 222. After the water is released, under the action of the coil spring 271, the capstan 27 rotates and resets, and the wire rope 247 is reeled in, so that the plug 246 moves up and resets. After the first electromagnet 228 and the second electromagnet 229 are started in sequence, the second electromagnet 229 will absorb the first electromagnet 228, and the first electromagnet 228 slides inward along the second limit hole 227, compressing the second spring 2210, so that the push rod body 224 slides further inward, so that the second lock plate 243 and the first lock plate 242 are both disengaged from the block 238, so that the plug 246 slides along the fourth shell 24 to the lowest position, and the drain valve 31 is opened at this time. When the second electromagnet 229 loses power, the first electromagnet 228 automatically resets under the action of the second spring 2210; the movement of the connecting rod assembly 23 is specifically as follows: the push rod body 224 drives the hollow guide rail 239, and the hollow guide rail 239 drives the first connecting rod 232 and the second connecting rod 236 through the first connecting member 231, and the first connecting rod 232 rotates on the second connecting member 233, driving the third spring 235 to deform, and the second connecting rod 236 drives the third connecting rod 237 to deflect on the cover plate 241, so that the stopper 238 on the third connecting rod 237 leaves the second lock plate 243, and after the push rod body 224 extends, it drives the hollow guide rail 239 to reset, so that the first connecting member 231 drives the first connecting rod 23 2 and the second connecting rod 236 are reset. During this process, the third spring 235 provides auxiliary resetting tension, and the blocking rod 234 limits the final position of the first connecting rod 232; during the execution of the watering task, the control handle and the camera 32 send data to the control center 4 in real time, which is stored by the data storage module 46, and the real-time monitoring module 44 visualizes the data. The data content includes the helicopter position, watering amount and fire zone image. The watering amount is determined by the watering amount statistics unit 112 according to the number of watering times. The automatic scheduling module 43 evaluates the fire intensity based on the fire zone image and dynamically adjusts the watering task. The control center 4 uses the remote command module 45 to establish contact with the helicopter and manually intervene in the watering task;Among them, the first housing 1 and the grip 11 are the outer shell of the control handle, the main control unit 16 in the circuit module 15 is used to execute control instructions, the positioning unit 17 is used to obtain position data, the power management unit 111 is used to manage power, the second housing 21 is the outer shell of the lock device 2, the third housing 221 is the outer shell of the electromagnetic push rod 22, the three fixing rods 25 are used to fix a third spring 235 and two fourth springs 244 respectively, and the guide frame 26 is used to guide the wire rope 247. ;
