Description

Technical Field

[0001] The present invention relates to the technical field of forest fire prevention equipment, and more specifically, to a forest fire monitoring and early warning device based on Beidou. Background Technique

[0002] The forest fire monitoring and early warning device based on Beidou utilizes the high-precision positioning and communication capabilities of the Beidou satellite navigation system to provide strong technical support for forest fire prevention and control. These devices can track and accurately locate the fire point in real time, and combined with intelligent devices such as unmanned aerial vehicles and sensors, they can achieve efficient monitoring and early warning of forest fires, playing an important role in forest fire prevention and control and providing a solid guarantee for protecting the green homeland.

[0003] The patent with the publication number CN219130025U discloses a forest fire prevention monitoring device, which includes an equipment support frame and a monitoring head fixedly installed at the top of the equipment support frame. A monitoring camera and a carbon dioxide concentration sensor are fixedly installed on the monitoring head. The threaded sleeve threaded with the threaded rod drives the wiping box to wipe the dust on the surface of the monitoring camera, ensuring that the monitoring camera always maintains a good monitoring effect. There is no need for staff to wipe on-site, effectively solving the defect that due to the accumulation of dust on the monitoring camera, an effective early warning cannot be made for the spread of forest fires.

[0004] However, when many traditional monitoring devices are designed, their monitoring directions are fixed, or adjusting the direction requires manually moving the entire device. This not only increases the complexity of the operation but also limits the flexibility of monitoring. Especially when it is necessary to monitor multiple directions or a large area, it is particularly inconvenient. At the same time, the key components such as the camera and sensor of the traditional monitoring device are directly exposed to the external environment. Due to the lack of an effective protection mechanism, when facing bad weather or a fire, the existing devices often have difficulty ensuring the safety of the monitoring equipment, resulting in frequent maintenance and replacement of the equipment and increasing the use cost.

[0005] In view of this, we propose a forest fire monitoring and early warning device based on Beidou. Summary of the Invention

[0054] In this embodiment, as Figure 4 shown, the storage cylinder 130 is fixedly connected to the top surface of the fixing cylinder 110 by bolts.

[0057] Specifically, the flap 141 and the plate end convex shaft 142 are integrally formed. The end of the plate end convex shaft 142 extends into the inner part of the limit sliding groove 132, and the shaft end gear 143 is fixedly connected to the end position of the plate end convex shaft 142 through a pin.

[0058] Furthermore, after the shaft end gear 143 is toggled, it rotates, driving the plate end convex shaft 142 and the flap 141 to rotate together, so as to accommodate the wind direction sensor 600 and the wind speed sensor 700 into the inner part of the cylinder through groove 131.

[0059] In this embodiment, as Figure 6 shown, the driving device 200 includes two sets of symmetrically arranged electric push rods 210 and a T-shaped push rod 220 provided at the end of the telescopic rod of the electric push rod 210;

[0060] Specifically, the electric push rod 210 is fixedly connected to the bottom surface of the upper partition plate 120 through screws, and the top surface of the horizontal plate at the bottom of the T-shaped push rod 220 is clamped and fixed to the bottom end of the telescopic rod of the electric push rod 210.

[0061] Furthermore, after the electric push rod 210 is started, the position of the T-shaped push rod 220 can be changed.

[0062] In this embodiment, as Figures 7 - 9 shown, the monitoring angle adjustment device 300 includes a rotating cylinder 310 for providing an installation platform for the flame recognition camera 330 and a pressing part 320 provided at the central position inside the rotating cylinder 310;

[0063] Specifically, the rotating cylinder 310 includes a fixed cylinder body 311, a fixed ring body 312 provided at the central position inside the fixed cylinder body 311, and a limit bracket 313 provided on the bottom surface inside the fixed cylinder body 311. A ring wall convex groove 3120 is formed on the inner ring wall of the fixed ring body 312.

[0064] Furthermore, the pressing part 320 includes a pressing rod 321, a number of rod wall convex blocks 322 provided on the outer wall of the circular plate at the bottom end of the pressing rod 321, and a first pressure spring 323 provided below the pressing rod 321.

[0065] Further, the fixed cylinder body 311 is rotatably connected to the top surface of the lower partition plate 120. The fixed ring body 312 and the limiting bracket 313 are integrally formed with the fixed cylinder body 311. The flame recognition camera 330 is fixedly connected to the inner top surface of the fixed cylinder body 311 by screws.

[0066] Further, the circular plate at the bottom end of the pressing rod 321 is slidably connected to the inside of the fixed ring body 312. The rod wall convex block 322 is integrally formed with the pressing rod 321. The end of the rod wall convex block 322 extends into the inside of the ring wall convex groove 3120. The upper and lower ends of the first pressure spring 323 respectively abut against the top surface of the fixed cylinder body 311 and the bottom surface of the circular plate at the bottom end of the pressing rod 321.

[0067] Further, the electric push rod 210 in the control driving device 200 is started to drive the T-shaped push rod 220 to move downward, and then drive the pressing rod 321 in the pressing part 320 to move downward inside the fixed ring body 312. The rod wall convex block 322 on the fixed ring body 312 moves inside the ring wall convex groove 3120, so that the fixed ring body 312 together with the rotating cylinder 310 rotates by a certain angle as a whole, thereby changing the irradiation angle of the flame recognition camera 330, and the first pressure spring 323 changes the position of the pressing rod 321 through its own elastic force.

[0068] In this embodiment, as Figure 10 shown, the linkage device 400 includes a moving circular plate 410, a lifting plate 420 arranged below the moving circular plate 410, a plurality of connecting ropes 430 arranged between the moving circular plate 410 and the lifting plate 420, fixed frame bodies 440 arranged on the top surfaces of the front and rear ends of the moving circular plate 410, frame wall toothed plates 450 arranged on the outer side walls of the left and right ends of the fixed frame bodies 440, and a plurality of second pressure springs 460 arranged on the inner bottom surfaces of the fixed frame bodies 440;

[0069] Specifically, the moving circular plate 410 is slidably connected to the inside of the fixed cylinder 110. A square through groove that penetrates up and down is provided at the central position inside the moving circular plate 410 to provide a moving interval for the lifting plate 420. The two ends of the connecting rope 430 are adhesively fixed to the bottom surface of the moving circular plate 410 and the outer side wall of the lifting plate 420 respectively.

[0070] Further, the fixed frame body 440 is snap-fitted and fixed to the top surface of the moving circular plate 410. The frame wall toothed plate 450 is integrally formed with the fixed frame body 440 and meshes with the shaft end gear 143. The upper and lower ends of the second pressure spring 460 are respectively welded and fixed to the inner top surface of the fixed frame body 440 and the bottom surface of the groove wall of the limiting chute 132.

[0071] Further, control the electric push rod 210 to drive the T-shaped push rod 220 to move upward, and then drive the upper lifting plate 420 to move upward. At this time, one end of the connecting rope 430 moves upward together with the upper lifting plate 420, while the other end drives the entire movable circular plate 410 to move downward, thereby causing the entire position of the fixed frame 440 to move downward. During the downward movement of the frame wall tooth plate 450 on the outer wall of the fixed frame 440, it contacts the shaft end gear 143 and drives it to rotate.

[0072] Finally, it should be noted that the electric push rod 210 involved in the present invention is a general standard part or a component known to those skilled in the art. Its structure and principle can be known by those skilled in the art through technical manuals or through conventional experimental methods. At the idle place of this device, connect the electric push rod 210 to an external power source through a wire. The specific connection means should refer to the working principle in the present invention. The electrical components are electrically connected in accordance with the sequence of their subsequent operations. All of its detailed connection means are well-known technologies in the art.

[0073] When the Beidou-based forest fire monitoring and early warning device of the present invention is in use, the flame recognition camera 330 in the monitoring angle adjustment device 300 analyzes the spectral information of the forest through the internal spectral analysis device, while the air sensor 500 analyzes the atmospheric pressure, air temperature and humidity, and carbon dioxide information in the forest, and the wind direction sensor 600 and the wind speed sensor 700 respectively analyze the wind direction and wind speed of the forest. Multiple groups of sensors transmit the analyzed information to the electric control system installed in the fixed cylinder 110 later, and the electric control system sends a signal to the Beidou satellite, and then the satellite transmits the information of multiple groups of monitoring devices installed in the forest back to the signal base station built beside the forest, so as to monitor the forest environment in real time. The above is the prior art and will not be elaborated here;

[0074] When the Beidou-based forest fire monitoring and early warning device needs to adjust the monitoring range, control the electric push rod 210 in the driving device 200 to start, drive the T-shaped push rod 220 to move downward, and drive the lower pressure rod 321 in the lower pressure part 320 to move downward inside the fixed ring body 312;

[0075] The rod wall convex block 322 on the fixed ring body 312 moves inside the ring wall convex groove 3120, and causes the fixed ring body 312 and the rotating cylinder 310 as a whole to rotate by a certain angle, thereby changing the irradiation angle of the flame recognition camera 330;

[0076] When a forest fire breaks out or bad weather such as heavy rain occurs in the forest, control the electric push rod 210 to drive the T-shaped push rod 220 to move upward, and drive the upper lifting plate 420 to move upward;

[0077] At this time, one end of the connecting rope 430 moves upward together with the upper lifting plate 420, while the other end drives the entire movable circular plate 410 to move downward, thereby causing the entire position of the fixed frame 440 to move downward;

[0078] During the downward movement of the frame wall tooth plate 450 on the outer wall of the fixed frame 440, it contacts the shaft end gear 143 and drives it to rotate, thereby driving the fixed position of the plate end convex shaft 142 together with the flap 141 to flip, so as to accommodate the wind direction sensor 600 and the wind speed sensor 700 installed on the flap 141 into the interior of the cylinder through groove 131, playing a role in protecting the monitoring sensors.

[0079] The foregoing description of the specific exemplary embodiments of the present invention is for the purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and obviously, many changes and variations are possible in light of the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the invention and its practical applications, so that those skilled in the art can implement and utilize the various different exemplary embodiments of the present invention, as well as various different selections and changes. The scope of the present invention is intended to be defined by the specification and its equivalents.
