Description

Technical Field

[0001] This invention relates to the field of forest fire prevention technology, specifically a fire early warning device for forest fire prevention. Background Technology

[0002] Forest fires are the most dangerous enemy of forests and the most terrible disaster for forestry, bringing the most harmful and devastating consequences. Forest fires not only burn down large areas of forest and harm animals within them, but also reduce the forest's reproductive capacity, cause soil depletion, damage the forest's water conservation capacity, and can even lead to an imbalance in the ecological environment.

[0003] To prevent fires, fire warning devices are usually installed in forests to remind people entering the forest to be more aware of fire prevention. However, existing fire warning devices are usually buried in the soil. Rainwater flows quickly in forests and often contains soil, which has a strong impact force and can easily cause the fire warning devices to loosen, tilt, or even fall over. Therefore, in view of the above situation, there is an urgent need to develop a fire warning device for forest fire prevention to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a fire early warning device for forest fire prevention, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A forest fire early warning device includes: Base; A fixed housing, which is fixedly connected to the base; A warning mechanism, which is slidably connected to the fixed shell, is used to provide early warning to passing personnel; A fixing mechanism is disposed between the fixing shell and the base, and is connected to the warning mechanism; The fixing mechanism includes: A control component, which is fixedly connected and disposed inside the fixed housing; A positioning component, which is connected to the base and the control component, is used to cooperate with the control component to achieve multiple fixations of the base; A lifting assembly is disposed between the control assembly and the warning mechanism, and is connected to the fixed housing, for use in conjunction with the control assembly to extend and retract the warning mechanism.

[0006] Compared with the prior art, the beneficial effects of the present invention are: When the device is in operation, the base contacts the ground, and the control component drives the positioning component. The positioning component can achieve multiple fixations to the base, ensuring the stability of the connection between the base and the ground. The control component can also drive the lifting component, which can raise and lower the warning mechanism, completing the raising and lowering of the warning mechanism. The warning mechanism extends from the inside of the fixed shell, thereby warning passers-by and facilitating the transportation and carrying of the equipment. Compared with the prior art, fire warning devices are usually buried in the soil. However, rainwater flows quickly in forests and usually contains soil, which has a large impact force, easily causing the fire warning device to loosen, tilt, or even fall over. By setting up a fixing mechanism and using the positioning component, the device can be fixed in multiple ways, thereby ensuring the device's firmness in the soil, increasing the stability of the device, and enabling the raising and lowering of the device, thus improving the convenience of the device during transportation.

[0021] In this embodiment, a fixing rod 16 is fixedly connected between the top of the base plate 17 and the lifting plate 9. The fixing rod 16 is slidably connected to the shell wall of the base 1 and the fixed shell 2.

[0025] In this embodiment, the support plate 30 is threadedly connected to the adjusting rods 14 on both sides. Connecting boxes 31 are fixedly connected to the inner sides of the shell walls at both ends of the fixed shell 2. The first piston 32 includes a first push rod fixedly connected to the support plate 30. The other end of the first push rod is fixedly connected to the first piston. The first piston is slidably connected to the piston tube 33. The piston tube 33 is fixedly connected to the outer side of the bottom end of the connecting box 31. During the rotation of the adjusting rod 14, the support plate 30 can be raised and lowered. The support plate 30 can not only raise and lower the warning mechanism 3, but also raise and lower the first piston. As the first piston inserts into the inner side of the piston tube 33, the support plate 30 continues to move, allowing air to flow inside the connecting box 31. The air enters the inner side of the warning mechanism 3 along the connecting tube 34 and the rubber tube 35, driving the warning mechanism 3 and enabling its deployment. By setting the lifting assembly 7, it can cooperate with the control assembly 5 to raise and lower the warning mechanism 3. Furthermore, the warning mechanism 3 can be fully deployed after it has risen a certain distance, providing adequate protection for the warning mechanism 3.

[0026] In one embodiment of the present invention, please refer to Figure 1 and Figure 6 The warning mechanism 3 includes: a fixed frame 36, which is fixedly connected to the support plate 30; a support frame 37, which is disposed inside the fixed frame 36 and connected to the fixed frame 36 via a rotating rod 38; a display screen 39, which is fixedly connected to the support frame 37 and is used to warn passersby; suction blocks 40, which are symmetrically disposed on both sides of the display screen 39 and fixedly connected to the support frame 37, and are used to cooperate with the fixed frame 36 to fix the support frame 37; and a flipping assembly 41, which is disposed between the rotating rod 38 and the lifting assembly 7, and is used to cooperate with the lifting assembly 7 to drive the rotating rod 38 to flip the support frame 37.

[0027] In this embodiment, the fixing frame 36 is fixedly connected to the outer side of the top end of the support plate 30. Rotating rods 38 are rotatably connected to both sides of the top end of the fixing frame 36. A support frame 37 is provided between the two rotating rods 38, and the rotating rods 38 are fixedly connected to the support frame 37. The display screen 39 is disposed between the fixing frame 36 and the support frame 37, and is fixedly connected to the support frame 37. Adsorption blocks 40, made of magnets, are provided on both sides of the display screen 39 and are fixedly connected to the support frame 37. The magnetic force between the adsorption blocks 40 and the fixing frame 36 is... In addition to the adsorption connection, the outer side of the fixing frame 36 is also equipped with a buzzer that is fixedly connected to the support plate 30. By setting the warning mechanism 3, the fixing frame 36 and the support frame 37 can protect the display screen 39. As the support plate 30 rises, the air discharged from the inside of the connecting box 31 enters the inside of the flipping assembly 41 along the connecting pipe 34 and the rubber tube 35. The flipping assembly 41 drives the rotating rod 38 to rotate, realizing the flipping of the support frame 37. The support frame 37 drives the display screen 39 to rotate, exposing the display screen 39, thereby realizing the warning to passers-by.

[0028] In one embodiment of the present invention, the flipping assembly 41 includes: a transmission box 47, which is fixedly connected to the support plate 30 and connected to the lifting assembly 7 via a vent pipe 48; a control pipe 46, which is disposed between the rotating rod 38 and the transmission box 47 and fixedly connected to the transmission box 47; an adjusting plate 44, which is disposed between the control pipe 46 and the rotating rod 38 and connected to the control pipe 46 via a second piston member 45; and a rack 43, which is fixedly connected to the adjusting plate 44 and meshes with a gear 42 fixedly connected to the outside of the rotating rod 38, for cooperating with the movement of the adjusting plate 44 to achieve the flipping of the support frame 37.

[0029] In this embodiment, the transmission box 47 is fixedly connected to the outer side of the top of the support plate 30. A control tube 46 is fixedly connected to the top of the transmission box 47. The second piston 45 includes a second piston slidably connected to the inner side of the control tube 46. A second push rod is fixedly connected between the second piston and the adjusting plate 44. A rack 43 is fixedly connected to the outer side of the top of the adjusting plate 44. The rack 43 meshes with a gear 42 fixedly connected to the outer side of the rotating rod 38. Air enters the inner side of the transmission box 47 along the vent pipe 48, realizing the lifting and lowering of the second piston inside the control tube 46, thereby realizing the movement of the adjusting plate 44. The adjusting plate 44 drives the rack 43 to move, which, in conjunction with the gear 42, realizes the rotation of the rotating rod 38. By setting the flipping component 41, the support frame 37 can be flipped in conjunction with the operation of the lifting component 7, so that the display screen 39 can be fully protected during use, which helps to extend the service life of the equipment.

[0030] In one embodiment of the present invention, the invention further includes: a top plate 49 disposed on the outside of the support frame 37; a fixed column 51 disposed between the top plate 49 and the support plate 30 and fixedly connected to the support plate 30; and a movable rod 50 disposed between the top plate 49 and the fixed column 51, fixedly connected to the top plate 49, and connected to the fixed column 51 via a second elastic member.

[0031] In this embodiment, a plurality of fixed posts 51 are symmetrically arranged on the outer side of the fixed frame 36 and fixedly connected to the support plate 30. A movable rod 50 is slidably connected to the inner side of the fixed post 51. A second elastic element, which is a spring, is fixedly connected between the movable rod 50 and the fixed post 51. The top end of the movable rod 50 is fixedly connected to the top plate 49. By setting the top plate 49, the warning mechanism 3 can be sheltered from wind and rain, and after being recycled, it can cooperate with the fixed shell 2 to achieve all-round protection of the warning mechanism 3, which helps to improve the service life of the equipment.

[0032] In one embodiment of the present invention, a sensor 52 is fixedly connected to the outside of the fixed shell 2. The sensor 52 is electrically connected to the controller. The sensor 52 can detect wind force and rainfall. When the wind force is too strong or the rainwater flow speed is too fast, the sensor 52 drives the control component 5 through the controller, so that the warning mechanism 3 is retracted into the inside of the fixed shell 2 to protect the equipment.

[0033] This forest fire early warning device, through the installation of a fixing mechanism 4 and the use of a positioning component 6, achieves multiple fixations to the device, ensuring its stability within the soil and increasing its overall stability. It also allows for easy deployment and retrieval of the device, enhancing its ease of transport. A control component 5 and a telescopic component 11 drive the lifting plate 9 to move. The lifting plate 9 then drives the positioning component 6 to insert into the soil, achieving initial fixation of the base 1. A driving component 10 rotates the driving rod 12, which, via pulleys and belts, drives the adjusting rods 14 on both sides to rotate. The adjusting rods 14, on one hand, drive the lifting component 7 to raise and lower the warning mechanism 3; on the other hand, they provide a secondary drive to the positioning component 6, achieving further fixation of the device and ensuring its stability within the soil, thus increasing the device's overall stability. By setting the positioning component 6, the lifting plate 9, driven by the telescopic component 11, works with the fixing rod 16 to lift the base plate 17. The base plate 17 drives the positioning nail 18 to insert into the soil, completing the initial fixation of the base 1. The adjusting rod 14 can drive the reinforcing component 29. The reinforcing component 29, together with the positioning nail 18 inserted into the soil, achieves multiple fixations for the equipment, ensuring the equipment's firmness in the soil and thus increasing the stability of the device. By setting the lifting component 7, it can work with the control component 5 to lift the warning mechanism 3. It can also unfold the warning mechanism 3 after it has risen a certain distance, providing full protection for the warning mechanism 3. By setting the top plate 49, it can shield the warning mechanism 3 from wind and rain, and after being retrieved, it can work with the fixing shell 2 to achieve all-round protection for the warning mechanism 3, which helps to extend the service life of the equipment.

[0034] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
