The intelligent warning device for forest fire prevention provided by this patent has the advantages of voice playback function and strong protection ability.

[0004] However, the device still has some shortcomings: the device can play voice prompts to alert people to pay attention to forest fire prevention, but the equipment has certain shortcomings in monitoring forest fires. Therefore, when a small fire or abnormal situation occurs inside the forest, it is difficult for forest rangers to be informed in time and extinguish the fire in time. The fire may easily increase due to untimely alarm, causing forest damage. Summary of the invention

[0005] The present invention provides a warning device for forest fire prevention, which solves the problem in the related art that when a small fire or abnormal situation occurs inside the forest due to obstruction by grass or shrubs, it is difficult for forest rangers to be informed in time and thus put out the fire in time.

[0006] The technical solution of the present invention is as follows: A warning device for forest fire prevention, comprising a base, a slide groove is arranged at the bottom of the base, an electric turntable is arranged at the top of the base, and an electric telescopic rod is arranged at the top of the electric turntable; An anti-missing device is provided at the top of the telescopic end of the electric telescopic rod, a stabilizing device is provided at the periphery of the anti-missing device, and a pressing device is provided above the stabilizing device; The anti-missing device includes an alarm mechanism, the bottom of which is fixedly installed on the top of the telescopic end of the electric telescopic rod, a smoke gas measuring instrument is fixedly installed on the back of the inner wall of the alarm mechanism, a recording component is fixedly installed at the center of the top of the alarm mechanism, a number of vertical rods are fixedly installed at the top corners of the alarm mechanism, a protective top plate is fixedly installed on the top of the vertical rods, the protective top plate is inclined, a circular plate is fixedly installed at the bottom edge of the alarm mechanism, a number of conical columns are fixedly installed at the bottom edge of the circular plate, an extension plate is slidably installed inside the base slide groove, and a square groove is opened inside the extension plate, and an L-shaped arc panel is fixedly installed on the top of the extension plate away from the base.

[0007] Optionally, several of the vertical rods are symmetrically distributed on the top of the alarm mechanism, and several of the conical columns are equidistantly distributed on the bottom of the circular ring plate. The outer walls of the conical columns are located on the arc motion trajectory of one end of the L-shaped arc panel close to the top of the electric telescopic rod. The entire device is placed in the forest, and the alarm mechanism plays voice to warn pedestrians while monitoring the forest fire situation. When the alarm mechanism changes the smoke detection direction and the monitoring height irregularly and automatically, the electric turntable starts, and the electric turntable rotates along the top of the base, driving the electric telescopic rod to rotate. At the same time, the electric telescopic rod starts, and the telescopic end of the electric telescopic rod drives the alarm mechanism to achieve lifting and rotation movement, and the alarm mechanism drives the smoke meter to move synchronously. At the same time, the alarm mechanism drives the recording component to rotate and rise. This expands the working range of the smoke gas measuring instrument and the recording component. When a fire occurs, the alarm mechanism sounds an alarm and transmits a signal to the data terminal through the wireless terminal. At the same time, the alarm mechanism drives the vertical rod to revolve and move upward, and the vertical rod drives the protective top plate to move synchronously. The top slope of the protective top plate guides rainwater, fallen leaves and other materials; the alarm mechanism realizes revolution and upward movement through the electric telescopic rod, driving the circular plate to move synchronously. During the process of the circular plate's revolution and upward movement, it will resist the outer wall of the conical column to generate a resistance force. During the gradual rise of the circular plate's revolution, the circular plate resists the L-shaped arc panel and gradually moves away from the base. The L-shaped arc panel pulls the extension plate from the inside of the base slide groove to gradually extend away from the center of the base. At this time, the extension plate effectively expands the contact area between the base and the ground.

[0008] Optionally, the stabilizing device comprises a long block, a plurality of oblique cone rods and a plurality of U-shaped telescopic plates, the outer wall of the long block is slidably mounted inside the square groove of the extension plate, the tops of the plurality of oblique cone rods are equidistant and fixedly mounted on the bottom of the long block, the bottoms of the plurality of U-shaped telescopic plates are symmetrical and fixedly mounted on both ends of the top of the extension plate, the bottom of the telescopic end of the U-shaped telescopic plate contacts the top edge of the long block, and when the extension plate moves away from the base through the L-shaped arc panel, it drives the long block to move synchronously, the long block drives the oblique cone rod to slide synchronously along the ground, and at the same time, the extension plate drives the U-shaped telescopic plate to move synchronously, and the bottom of the telescopic end of the U-shaped telescopic plate always contacts the top of the long block, so in the process of the oblique cone rod sliding along the ground, it gradually penetrates into the ground through the cone surface.

[0009] Optionally, the stabilizing device also includes a U-shaped plate, a plurality of friction wheels, a screw rod, a transverse plate and a trapezoidal inclined block, both ends of the U-shaped plate are fixedly mounted on the side of the U-shaped telescopic plate close to the center of the extension plate, a plurality of friction wheels are symmetrically and rotatably mounted inside the end of the U-shaped plate close to the center of the base, both ends of the screw rod are fixedly mounted on the side of the friction wheel close to the center of the U-shaped plate, the transverse plate passes through the inside and is spirally mounted on the outer wall of the screw rod, and the bottom of the trapezoidal inclined block is fixedly mounted on the top of the long block.

[0010] Optionally, the outer wall of the friction wheel contacts the top of the base, the outer wall of the screw rod is a non-self-locking spiral, and the transverse plate is slidably installed on the inner wall of the U-shaped plate away from one end of the screw rod, and the top inclined surface of the trapezoidal inclined block is located on the movement trajectory of the transverse plate. In the process of the U-shaped telescopic plate moving away from the base, the U-shaped plate is driven to move synchronously, and the long block drives the trapezoidal inclined block to move synchronously. The U-shaped plate pulls the friction wheel to slide synchronously along the top of the base and generates friction force, and the friction wheel begins to rotate inside the U-shaped plate through the friction force, and the friction wheel drives the screw rod to rotate when it rotates. When the screw rod rotates, it drives the spirally connected transverse plate through the spiral groove on its own outer wall to generate a force for horizontal movement, and the transverse plate will gradually slide along the top of the trapezoidal inclined block and its inclined surface. At this time, the downward pressure generated by the transverse plate on the trapezoidal inclined block gradually increases.

[0011] Optionally, the downward pressing device includes a contact plate, a hollow U-frame and an elastic telescopic plate, the bottom of the contact plate is fixedly mounted on the top of the transverse plate, the bottom of the hollow U-frame is fixedly mounted on the top of the U-shaped plate, the top of the fixed end of the elastic telescopic plate is fixedly mounted on the top of the inner wall of the hollow U-frame, the top arc surface of the contact plate is in contact with the telescopic end of the elastic telescopic plate, and the transverse plate drives the contact plate to move synchronously during the horizontal movement, and the U-shaped plate drives the hollow U-frame to move synchronously, so the contact plate will contact the telescopic end of the elastic telescopic plate at the bottom of the hollow U-frame during the transverse movement of the contact plate, as the top arc surface of the contact plate contacts the telescopic end of the elastic telescopic plate, when the telescopic end of the elastic telescopic plate contracts upward, the elastic force of the built-in spring prompts the contact plate to generate a downward movement force, and the downward pressure of the transverse plate on the trapezoidal inclined block is further enhanced through the transmission of force.

[0012] Optionally, the pressing device also includes a linkage plate, a cylinder, a plurality of inclined plates, a friction plate, an elastic arc sheet and a knocking column. The outer wall of the linkage plate passes through and is fixedly installed inside the telescopic end of the elastic telescopic plate. The bottom of the cylinder is fixedly installed on the top of the linkage plate. If the bottom of the inclined plate is symmetrical and hinged at the outer wall of the cylinder, the top of the friction plate is slidably installed on the top of the inner wall of the hollow U frame, both ends of the elastic arc sheet are fixedly installed on the side of the inclined plate close to the cylinder, and the bottom of the knocking column is fixedly installed on the bottom of the inner wall of the elastic arc sheet.

[0013] Optionally, a torsion spring is arranged between the bottom of the inclined plate and the cylinder, the bottom of the friction plate is hinged to the top of the inclined plate, the top of the inner wall of the hollow U-frame is located on the movement trajectory of the top of the knocking column, and when a single elastic telescopic plate is resisted by the contact plate and moves upward, it drives the linkage plate to move synchronously, and the linkage plate drives the telescopic ends of the remaining elastic telescopic plates to telescope synchronously, thereby expanding the resistance force of the telescopic end of the single elastic telescopic plate on the contact plate. At the same time, the linkage plate drives the cylinder to move synchronously, the cylinder drives the inclined plate to move synchronously, and the inclined plate drives the friction plate to move synchronously. The friction plate is limited by the top of the inner wall of the hollow U-frame, prompting the hinge axis of the inclined plate to start rotating, and the inclined plate takes the hinge axis as the The axis drives the friction plate to slide along the top of the inner wall of the hollow U frame away from the cylinder. During the sliding process, friction will be generated between the friction plate and the top of the inner wall of the hollow U frame, thereby further increasing the resistance force of the telescopic end of the elastic telescopic plate during extension and contraction, and the friction plate will pull the elastic arc piece to move synchronously and deform during the sliding process. When the elastic arc piece is deformed, it drives the knocking column to move toward the top of the inner wall of the hollow U frame and knock. The hollow U frame generates slight vibration through the knocking of the knocking column, and the U-shaped plate at the bottom of the hollow U frame is caused to vibrate synchronously through the transmission of force, thereby prompting the transverse plate to carry a slight vibration force and slide along the inclined surface of the trapezoidal inclined block.

[0014] The working principle and beneficial effects of the present invention are: 1. In the present invention, by setting the anti-missing device, through the alarm mechanism, the smoke meter, the video recording component, the vertical rod, the protective top plate, the circular plate, the conical column, the extension plate and the L-shaped arc panel, the alarm mechanism can effectively expand the measuring and recording range of the smoke meter and the video recording component during the movement, so as to avoid the small fire or abnormal situation inside the forest due to the obstruction of grass or shrubs, which makes it difficult for the forest ranger to know in time and put out the fire in time, and effectively improve the timeliness of the alarm to prevent the occurrence of fire; at the same time, when the alarm mechanism is in operation, the extension plate can automatically extend to expand the contact area between the base and the ground, shortening the installation and debugging time when the device is put into use as a whole, and avoiding the tilting and collapse phenomenon caused by the increase of wind force when the alarm mechanism is raised, thereby improving the stability of the warning equipment during the overall use and reducing the maintenance frequency.

[0015] 2. In the present invention, through the setting of the stabilizing device, through the cooperation of the extension plate, the long block, the inclined cone rod, the U-shaped telescopic plate, the U-shaped plate, the friction wheel, the screw, the transverse plate and the trapezoidal inclined block, the inclined cone rod gradually penetrates into the ground during the movement, and when the inclined cone rod is resisted by the harder ground and generates an upward movement force, the telescopic end of the U-shaped telescopic plate provides downward pressure for the inclined cone rod, so that the inclined cone rod is always close to the ground, ensuring that the inclined cone rod can gradually penetrate into the ground during the movement, further warning the stability of the equipment after extension; and relying on the gradual increase of the downward pressure of the trapezoidal inclined block on the transverse plate, the long block drives the inclined cone rod to move, so that it can gradually penetrate into the ground instead of all at once, causing the extension process of the extension plate to be blocked, while ensuring that the inclined cone rod can stably penetrate into the ground without affecting the alarm mechanism's revolution monitoring and recording process.

[0016] 3. In the present invention, by setting the downward pressure device, through the cooperation of the transverse plate, the resistance plate, the hollow U frame, the elastic telescopic plate, the linkage plate, the cylinder, the inclined plate, the friction plate, the elastic arc plate and the knocking column, the downward pressure of the transverse plate on the inclined cone rod is increased by relying on the elastic telescopic plate, so that the inclined cone rod can penetrate deeper into the ground during the movement, that is, the overall strong wind resistance of the warning device is improved, and the possibility of the entire device being tilted after being hit by wild animals when stored in the forest is reduced, and the tilt and blur of the recording image of the recording component is prevented from affecting the monitoring; at the same time, the downward pressure of the transverse plate during the transverse movement is increased for the second time, while the movement speed of the transverse plate is slowed down, so that the inclined cone rod has sufficient time and downward pressure to penetrate into the ground, and the inclined cone rod is prevented from being damaged by penetrating too quickly, and the vibration force carried by the transverse plate reduces the sense of stagnation when sliding on the inclined surface of the trapezoidal inclined block.

[0024] A number of vertical rods 44 are symmetrically distributed at the top of the alarm mechanism 41, and a number of conical columns 47 are equidistantly distributed at the bottom of the circular plate 46. The outer wall of the conical column 47 is located on the arc motion trajectory of one end of the L-shaped arc panel 49 close to the top of the electric telescopic rod 3. Through the above cooperation, the alarm mechanism 41 can effectively expand the measurement and recording range of the smoke meter 42 and the recording component 43 during the movement, so as to avoid the small fire or abnormal situation inside the forest due to the obstruction of grass or shrubs, which makes it difficult for forest rangers to know in time and put out in time, effectively improve the timeliness of the alarm to prevent fire. At the same time, the protective top plate 45 blocks and guides fallen branches or rainwater in the forest to prevent the alarm mechanism 41 from being damaged; through the above cooperation, when the alarm mechanism 41 is self-operating, the extension plate 48 can automatically extend to expand the contact area between the base 1 and the ground, shortening the installation and debugging time of the overall device when it is deployed, and avoiding the tilting and collapse phenomenon caused by the increase of wind force when the alarm mechanism 41 is raised, thereby improving the stability of the overall use of the warning equipment and reducing the maintenance frequency.

[0025] In this embodiment, the device is placed in the forest as a whole, and the alarm mechanism 41 plays voice to warn pedestrians, and monitors the forest fire situation at the same time. When the alarm mechanism 41 changes the smoke detection direction and monitoring height at irregular intervals and automatically, the electric turntable 2 is started, and the electric turntable 2 rotates along the top of the base 1 to drive the electric telescopic rod 3 to rotate. At the same time, the electric telescopic rod 3 is started, and the telescopic end of the electric telescopic rod 3 drives the alarm mechanism 41 to achieve lifting and rotation movement, and the alarm mechanism 41 drives the smoke measuring instrument 42 to move synchronously, and the alarm mechanism 41 drives the recording component 43 rotates and rises, thereby expanding the working range of the smoke meter 42 and the video recording component 43.

When a small fire or abnormal situation occurs inside the forest, it is difficult for the forest ranger to be informed in time and put out the fire in time, which effectively improves the timeliness of the alarm to prevent the occurrence of fire. At the same time, the protective top plate 45 blocks and guides fallen branches or rainwater in the forest to prevent the alarm mechanism 41 from being damaged; the alarm mechanism 41 realizes revolution through the electric telescopic rod 3 and drives the circular plate 46 to move synchronously when it moves upward. During the revolution and upward movement of the circular plate 46, it will resist the outer wall of the conical column 47 to generate a resistance force. During the gradual upward revolution of the circular plate 46, the circular plate 46 resists the L-shaped arc panel 4. 9 gradually moves away from the base 1, and the L-shaped arc panel 49 pulls the extension plate 48 to extend from the inside of the base 1 slide slot gradually toward the center of the base 1. At this time, the extension plate 48 effectively expands the contact area between the base 1 and the ground. Through the above cooperation, when the alarm mechanism 41 is self-operating, the extension plate 48 can automatically extend to expand the contact area between the base 1 and the ground, shortening the installation and debugging time of the overall device when it is deployed, and at the same time avoiding the tilting and collapse phenomenon caused by the increase of wind force when the alarm mechanism 41 is raised, thereby improving the stability of the warning equipment during overall use and reducing the maintenance frequency.

[0026] Example 2 Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: Compared with embodiment 2, further, it also includes a stabilizing device 5 and a pressing device 6; The stabilizing device 5 includes a long block 51, a plurality of inclined cone rods 52 and a plurality of U-shaped telescopic plates 53. The outer wall of the long block 51 is slidably installed inside the square groove of the extension plate 48. The tops of the plurality of inclined cone rods 52 are equidistant and fixedly installed at the bottom of the long block 51. The bottoms of the plurality of U-shaped telescopic plates 53 are symmetrical and fixedly installed at both ends of the top of the extension plate 48. The bottom of the telescopic end of the U-shaped telescopic plate 53 contacts the top edge of the long block 51. Through the above cooperation, the inclined cone rod 52 gradually penetrates into the ground during the movement, and when the inclined cone rod 52 is resisted by the harder ground and generates an upward movement force, the telescopic end of the U-shaped telescopic plate 53 provides downward pressure for the inclined cone rod 52, so that the inclined cone rod 52 is always close to the ground, ensuring that the inclined cone rod 52 can gradually penetrate into the ground during the movement, further warning the stability effect of the equipment after extension.

[0027] The stabilizing device 5 also includes a U-shaped plate 54, a plurality of friction wheels 55, a screw rod 56, a transverse plate 57 and a trapezoidal inclined block 58.

Through the above cooperation, the downward pressure of the trapezoidal inclined block 58 by the transverse plate 57 is gradually increased, so that the long block 51 drives the inclined cone rod 52 to move, and it can gradually penetrate into the ground instead of all at once, causing the extension process of the extension plate 48 to be blocked, while ensuring that the inclined cone rod 52 can stably penetrate into the ground without affecting the revolution monitoring and recording process of the alarm mechanism 41.

[0029] When in use, when the extension plate 48 moves away from the base 1 through the L-shaped arc panel 49, it will drive the long block 51 to move synchronously, and the long block 51 will drive the inclined cone rod 52 to slide synchronously along the ground, and at the same time, the extension plate 48 will drive the U-shaped telescopic plate 53 to move synchronously, and the bottom of the telescopic end of the U-shaped telescopic plate 53 will always resist the top of the long block 51.

At this time, the downward pressure generated by the transverse plate 57 on the trapezoidal inclined block 58 gradually increases. Through the above cooperation, the downward pressure on the trapezoidal inclined block 58 by the transverse plate 57 gradually increases, so that the long block 51 drives the inclined cone rod 52 to move in the process, which can gradually penetrate into the ground instead of all at once, causing the extension process of the extension plate 48 to be blocked, while ensuring that the inclined cone rod 52 can stably penetrate into the ground without affecting the revolution monitoring and recording process of the alarm mechanism 41; The downward pressure device 6 includes a contact plate 61, a hollow U-frame 62 and an elastic telescopic plate 63. The bottom of the contact plate 61 is fixedly mounted on the top of the transverse plate 57, the bottom of the hollow U-frame 62 is fixedly mounted on the top of the U-shaped plate 54, and the top of the fixed end of the elastic telescopic plate 63 is fixedly mounted on the top of the inner wall of the hollow U-frame 62. The top arc surface of the contact plate 61 contacts the telescopic end of the elastic telescopic plate 63. Through the above cooperation, the elastic telescopic plate 63 is used to increase the downward pressure of the transverse plate 57 on the inclined cone rod 52, so that the inclined cone rod 52 penetrates deeper into the ground during movement, that is, the overall strong wind resistance of the warning device is improved, and the possibility of the overall device being tilted after being hit by wild animals when stored in the forest is reduced, so as to prevent the tilt and blur of the recording image of the recording component 43 from affecting monitoring.

[0030] The pressing device 6 also includes a linkage plate 64, a cylinder 65, a plurality of inclined plates 66, a friction plate 67, an elastic arc piece 68 and a knocking column 69.

If the bottom of the inclined plate 66 is symmetrical and hinged at the outer wall of the cylinder 65, the top of the friction plate 67 is slidably installed on the top of the inner wall of the hollow U frame 62, both ends of the elastic arc piece 68 are fixedly installed on the side of the inclined plate 66 close to the cylinder 65, and the bottom of the knocking column 69 is fixedly installed on the bottom of the inner wall of the elastic arc piece 68.

[0031] A torsion spring is arranged between the bottom of the inclined plate 66 and the cylinder 65, the bottom of the friction plate 67 is hinged to the top of the inclined plate 66, and the top of the inner wall of the hollow U-frame 62 is located on the movement trajectory of the top of the knocking column 69. Through the above coordination, the linkage plate 64 and the friction plate 67 further enhance the resistance force when the telescopic end of the elastic telescopic plate 63 contracts upward on the original basis, that is, the downward pressure of the transverse plate 57 is secondary lifted during the transverse movement process, while the movement speed of the transverse plate 57 is slowed down, so that the inclined cone rod 52 has sufficient time and downward pressure to penetrate into the ground, preventing the inclined cone rod 52 from penetrating too quickly and being damaged, and the transverse plate 57 carries the vibration force to reduce the feeling of stagnation when sliding on the inclined surface of the trapezoidal inclined block 58.

[0032] When in use, the horizontal movement of the transverse plate 57 drives the contact plate 61 to move synchronously, and the U-shaped plate 54 drives the hollow U frame 62 to move synchronously. Therefore, during the transverse movement of the contact plate 61, it will contact the telescopic end of the elastic telescopic plate 63 at the bottom of the hollow U frame 62. As the arc surface of the top of the contact plate 61 contacts the telescopic end of the elastic telescopic plate 63, when the telescopic end of the elastic telescopic plate 63 contracts upward, the elastic force of the built-in spring causes the contact plate 61 to generate a downward movement force, and the downward pressure of the transverse plate 57 on the trapezoidal inclined block 58 is further enhanced through the transmission of force. Through the above cooperation, the elastic telescopic plate 63 increases the downward pressure of the transverse plate 57 on the inclined cone rod 52, so that the inclined cone rod 52 During the movement, the depth of the ground is deeper, which improves the overall strong wind resistance of the warning device and reduces the possibility of the device being tilted after being hit by wild animals when stored in the forest, thereby preventing the tilt and blur of the recording image of the recording component 43 from affecting monitoring; when a single elastic expansion plate 63 is resisted by the contact plate 61 and moves upward, it drives the linkage plate 64 to move synchronously, and the linkage plate 64 drives the remaining elastic expansion plates 63 to extend and retract synchronously, thereby expanding the resistance force of the single elastic expansion plate 63 to the contact plate 61, and at the same time the linkage plate 64 drives the cylinder 65 to move synchronously, the cylinder 65 drives the inclined plate 66 to move synchronously, and the inclined plate 66 drives the friction plate 67 to move synchronously. The wiping plate 67 is limited by the top of the inner wall of the hollow U-frame 62, causing the hinge axis of the inclined plate 66 to start rotating. The inclined plate 66 drives the friction plate 67 to slide along the top of the inner wall of the hollow U-frame 62 in the direction away from the cylinder 65 with the hinge axis as the axis. During the sliding process, friction plate 67 will generate friction with the top of the inner wall of the hollow U-frame 62, thereby further increasing the resistance of the elastic telescopic plate 63 during the telescopic extension. In addition, during the sliding process of friction plate 67, elastic arc piece 68 is pulled to move synchronously and deform. When elastic arc piece 68 is deformed, it drives knocking column 69 to move toward the top of the inner wall of the hollow U-frame 62 and knock. The hollow U-frame 62 is knocked by knocking column 69 to produce Slight vibration is generated, and the U-shaped plate 54 at the bottom of the hollow U-frame 62 is caused to vibrate synchronously through the transmission of force, so that the transverse plate 57 can carry the slight vibration force to slide along the inclined surface of the trapezoidal inclined block 58. Through the above cooperation, the linkage plate 64 and the friction plate 67 are relied on to further enhance the resistance force when the telescopic end of the elastic telescopic plate 63 contracts upward on the original basis, that is, the downward pressure during the transverse movement of the transverse plate 57 is increased for the second time, while the movement speed of the transverse plate 57 is slowed down, so that the inclined cone rod 52 has sufficient time and downward pressure to penetrate into the ground, thereby preventing the inclined cone rod 52 from penetrating too quickly and being damaged, and the transverse plate 57 carries the vibration force to reduce the feeling of stagnation when sliding on the inclined surface of the trapezoidal inclined block 58.
