Description

Technical Field

[0001] The invention relates to the technical field of fire fighting and extinguishing, in particular to a water throwing device for forest fire protection. Background Art

[0002] Forest fires have always been a major threat to the ecological environment and human safety, causing serious impacts on forest resources, biodiversity and the lives of surrounding residents. Traditional forest fire extinguishing methods face many difficulties in practical applications. In mountainous areas with complex terrain, it is difficult for fire trucks to reach the fire scene due to rugged roads and inconvenient transportation. If firefighters choose to enter on foot, not only will the journey take a long time, but they will also consume a lot of physical strength. When they arrive at the fire scene, they may have missed the best time to extinguish the fire, and the fire extinguishing efficiency is low. In addition, when faced with large-scale forest fires, existing fire-fighting equipment, such as conventional fire hoses and fire-extinguishing bombs, have limited coverage and cannot control the spread of fires over a large area in a short period of time, resulting in the continued expansion of the fire and causing more serious losses.

[0003] With the rapid development of drone technology, the use of drones for water-dropping and fire-fighting has brought new ideas for forest fire fighting. Drones are highly maneuverable and flexible, and can quickly reach areas that are difficult for fire trucks to reach, which to a certain extent makes up for the shortcomings of traditional fire-fighting methods. However, when drones perform water-dropping and fire-fighting tasks, there are also some urgent problems to be solved. Since drones need to maintain a certain safe distance from the fire source, they can only drop water from high altitudes, which makes it difficult to ensure the accuracy of water-dropping. In the process of falling from high altitudes, water is easily affected by various factors such as wind and airflow, deviates from the predetermined drop target, and cannot be accurately sprinkled at the fire source, reducing the fire-fighting effect and wasting precious water resources and fire-fighting time. Therefore, the development of a forest fire protection water-dropping device that can improve the accuracy of drone water-dropping is of great practical significance for improving the efficiency and effect of forest fire extinguishing.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] When a forest fire occurs, water can be added to the water tank 104 through the water filling port 105 with the help of a water pipe. Then, the operator can control the drone body 102 to quickly fly to the fire area based on the fire scene information obtained by the ground control center, and use the monitoring mechanism to monitor the fire and the environment around the drone. Then, the equipment can be hovered at a suitable position above the fire scene according to the size of the fire, and a small amount of water can be discharged from the water tank 104 with the help of a flow control mechanism, so that the discharged water forms a water line, and the state of the water line can be observed through the monitoring mechanism. The flight attitude of the drone body 102 is adjusted in time according to the position of the end of the water line, so that the end of the water line is accurately aligned with the fire point, and then the flow control mechanism is used to gradually increase the discharge volume, thereby realizing precise water delivery operation, which can effectively eliminate the waste of water caused by delivery errors, so that the water in the water tank 104 can be fully utilized to achieve efficient fire fighting operations.

[0032] As an embodiment of the present invention, please refer to Figure 2 , Figure 3 and Figure 4The flow control mechanism includes a telescopic cylinder 201 fixedly arranged on the side wall of the water tank 104, a lifting plate 202 is fixedly installed on the telescopic end of the telescopic cylinder 201, and a piston rod 203 is fixedly installed on the lower surface of the lifting plate 202. A mounting port is provided on the lower surface of the water tank 104, and a drain pipe 204 is fixedly installed in the mounting port. The outer wall of the drain pipe 204 is provided with water-permeable ports 205 distributed in an annular manner at equal distances, and the piston rod 203 is located in the drain pipe 204. A flow control component is also provided on the outer side of the piston rod 203 for adjusting the water output by moving the piston rod 203. When water is poured, the telescopic cylinder 201 can be used to move the water outflow. The movable lifting plate 202 moves upward, and the lifting plate 202 drives the piston rod 203 to move upward in the drain pipe 204, so that the water in the water tank 104 enters the drain pipe 204 through the water permeable port 205 and is discharged through the bottom end of the drain pipe 204, and the drainage volume can be controlled by the upward movement of the piston rod 203, until the water discharged from the drain pipe 204 forms a waterline. When the posture of the unmanned aerial vehicle 102 is controlled so that the end of the waterline is accurately aligned with the fire point, the lifting plate 202 can be further driven to move upward by the telescopic cylinder 1 201, thereby triggering the flow control component to quickly discharge a large amount of water in the water tank 104, thereby realizing a rapid fire extinguishing operation and having a better use effect.

When the piston rod 203 moves upward further, the piston rod 203 can drive the stepped plate 302 to move upward through the fixed rod 301, so that the spring 306 on the outside of the movable rod 303 is reset, and the sealing plate 305 at the bottom of the movable rod 303 is moved away from the drainage hole 307. At this time, the water in the water tank 104 can be discharged through the drainage hole 307, and as the piston rod 203 continues to move upward, the number of drainage holes 307 opened also increases, so that the drainage volume of the water tank 104 is proportional to the upward movement of the piston rod 203, and then the water injection volume can be flexibly controlled according to the fire size of different fire points, and the use effect is better.

[0034] As an embodiment of the present invention, please refer to Figure 2 , Figure 3and Figure 4 A water collecting bucket 308 is also fixedly installed on the lower surface of the water tank 104, and the drainage holes 307 are all connected to one end of the water collecting bucket 308.

[0036] As an embodiment of the present invention, please refer to Figure 7 and Figure 8 The monitoring unit includes a mounting tube 501, a fixing opening is provided on the outer wall of the adjustment plate 401, and the mounting tube 501 is fixedly arranged in the fixing opening, a universal ball 502 is rotatably arranged in the mounting tube 501, and a mounting rod 503 is fixedly installed on the outer wall of the universal ball 502, and a camera 504 is fixedly installed on the end of the mounting rod 503, and a positioning component is further provided on the upper surface of the adjustment plate 401 for adjusting the position of the universal ball 502 in the mounting tube 501, and the surrounding environment can be monitored through the camera 504, and the positioning component can be used to promote the universal ball 502 to rotate flexibly in the mounting tube 501, so that the direction of the camera 504 can be adjusted at multiple angles, so that the monitoring range is wider and the use effect is better.

When the position of the universal ball 502 in the installation tube 501 needs to be adjusted, the disc 603 can be moved by the extension of the telescopic cylinder three 602. The disc 603 can drive the universal ball 502 to rotate flexibly in the installation tube 501 with the help of the friction between the rubber gasket 604 and the universal ball 502, and the rotation direction can be flexibly controlled with the help of different extension amounts of different telescopic cylinders three 602, thereby realizing multi-angle control of the camera 504, and the use effect is better.

When the device lands, the water storage bag 704 will first contact the ground. Under the action of the gravity of the device, the water in the water storage bag 704 can be squeezed back into the water tank 104 along the support tube 701 until the support foot 705 at the bottom of the support plate 702 contacts the ground. The water storage bag 704 can play a good buffering role during the squeezing process, making the landing process of the device more stable and the use effect better.

[0039] During use, when a forest fire occurs, water can be added to the water tank 104 through the water filling port 105 with the help of a water pipe. Then, the operator can control the unmanned aerial vehicle 102 to quickly fly to the fire area according to the fire scene information obtained by the ground control center, and use the monitoring mechanism to monitor the fire and the surrounding environment of the unmanned aerial vehicle.
