Description

Technical Field

[0001] This utility model relates to the field of forest fire prevention technology, and in particular to a forest fire monitoring device. Background Technology

[0002] Forests are a vital component of maintaining the balance of Earth's ecosystems, serving multiple functions such as water conservation and air purification. However, forest fires, as a sudden and destructive natural disaster, often lead to the destruction of large areas of forest and even endanger human lives and property. Especially under dry, high-temperature, and other climatic conditions, fires spread rapidly and are extremely difficult to extinguish. Therefore, establishing an effective forest fire early warning and monitoring mechanism is a key technological approach to achieving early detection and early response.

[0003] Existing monitoring devices primarily rely on clamping to tree trunks for fixation, which is cumbersome to install. Furthermore, they are unsuitable for trees of varying diameters and surface shapes, prone to issues such as insecure clamping, tilting, and displacement. This type of structure is also highly dependent on installation location, making it difficult to deploy in complex terrains such as sparse shrubbery or open forest canopies. Some existing devices rely on temporary batteries or manual power replacement, lacking self-circulating power supply systems such as solar power and energy storage batteries. This makes them unsuitable for unattended, 24 / 7 continuous monitoring, and unsuitable for long-term deployment in remote, inaccessible forest areas, resulting in high maintenance costs and low operational reliability. Utility Model Content

[0004] The main purpose of this invention is to propose a forest fire monitoring device, which aims to solve the problems existing in the prior art.

[0005] To address the aforementioned problems, this utility model proposes a forest fire monitoring device, comprising: a support column and a triangular limiting bracket. The support column is a hollow cylinder with multiple longitudinal slots arranged around its sidewalls. Each slot has a sliding groove on one side of its inner wall for sliding engagement. A protective box is fixedly mounted on the top of the support column. A thermal imager is centrally mounted on one side of the inner wall of the protective box. Support rods are fixedly mounted around the top surface of the protective box. Solar panels are fixedly mounted on the top of multiple support rods. Limiting devices are provided at both the upper and lower ends of the inner wall of the support column. The triangular limiting bracket is disposed in the slots of the support column.

[0006] In one embodiment, a damping disc is provided at the top of the support column, the damping disc is fixedly connected to the bottom of the protective box, and extension columns are provided at both the upper and lower ends of the inner wall of the support column.

[0007] In one embodiment, the triangular limiting bracket includes a limiting shell and a connecting collar. Each of the three limiting shells has a supporting leg on its inner wall, a slider is fixedly provided on one side extension end of each of the three limiting shells, and the connecting collar is fixed at the top of each of the three limiting shells. The slider is slidably disposed in the groove structure on both sides of the grooved inner wall of the support column.

[0008] In one embodiment, the top surface of the inner wall of each of the three limiting shells is provided with a protruding block that cooperates with the protrusion on one side of the top of the three supporting legs to limit the opening and closing of the supporting legs.

[0009] In one embodiment, the center point of the top end of the extension column is rotatably connected to the limiting device. The limiting device includes a rotating shaft, and three supporting rods are arranged at intervals in the circumferential direction of the rotating shaft. A limiting block is fixedly provided on one side of each of the three supporting rods. A baffle is fixedly provided on the top surface of the extension column near the three supporting rods. A spring is fixedly provided on one side of each of the three baffles. The three springs are fixedly connected to one side of each of the three supporting rods.

[0010] In one embodiment, an energy storage battery is fixedly installed on one side of the inner wall of the protective box, a smoke sensor is fixedly installed at the center of the top surface of the protective box, a temperature sensor is fixedly installed on one side of the smoke sensor, and a humidity sensor is fixedly installed on the other side of the smoke sensor.

[0011] In one embodiment, the limiting device is disposed on the inner wall of the support column, and the three limiting blocks are slidably fitted in the limiting guide groove provided on the lower end of the slotted inner wall of the support column. The three supporting connecting rods extend outward through the guide hole opened in the side wall of the support column near the limiting block.

[0012] Beneficial effects:

[0013] 1. This device, with its support column and multiple support legs at the bottom of the triangular limiting bracket, can be stably deployed on the ground without relying on external structures such as trees for clamping, achieving independent deployment. It is particularly suitable for areas with complex terrain such as sparse shrubs and open forest undergrowth, where there are no suitable anchoring conditions. The bracket has a slider structure on its outer side, which slides and engages with the groove structure on the support column, ensuring precise positioning and stability of the triangular limiting bracket on the support column. Furthermore, the limiting devices at the top and bottom of the support column, through the cooperation of springs and baffles, allow for quick reset and storage of the triangular limiting bracket, improving the overall portability and repeated deployment efficiency of the device.

[0014] 2. The lower end of the support column is an extended conical structure, significantly longer than the support legs of the triangular limiting bracket. During use, this cylindrical end can be first inserted into the soil to establish initial orientation. Then, the three support legs of the triangular limiting bracket are deployed to provide multi-directional stability and anti-tilting fixation for the support column. The initial embedding of the support column after insertion into the ground effectively resists lateral disturbances and enhances the device's resistance to tilting in soft soil or under wind conditions. This ground-inserted initial positioning significantly reduces the risk of overturning before the triangular limiting bracket is deployed.

[0015] 3. The solar panel and energy storage battery structure is supported by struts to achieve automatic charging and continuously power modules such as thermal imagers and smoke / temperature and humidity sensors. No external energy or frequent maintenance is required. It supports 24-hour remote infrared scanning and fire early warning, which significantly improves the device's continuous monitoring capability in remote forest areas, saves labor costs and reduces the intensity of manual labor.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To achieve the above-mentioned utility model objectives, such as Figure 1-5 As shown, this utility model provides a forest fire monitoring device, including: a support column 1 and a triangular limiting bracket 2. The support column 1 is a hollow cylinder with multiple longitudinal slots arranged around its side walls. Each slot has a sliding groove on one side of its inner wall for sliding engagement. A protective box 4 is fixedly installed at the top of the support column 1. A thermal imager 5 is installed in the center of one side of the inner wall of the protective box 4. Support rods 10 are fixedly installed around the top surface of the protective box 4. Solar panels 9 are fixedly installed at the top of the multiple support rods 10. Limiting devices 3 are provided at both the upper and lower ends of the inner wall of the support column 1. The triangular limiting bracket 2 is installed in the slots of the support column 1. A damping disc 1 is installed at the top of the support column 1. 02. The damping disc 102 is fixedly connected to the bottom of the protective box 4. The upper and lower ends of the inner wall of the support column 1 are provided with extension columns 101. The triangular limiting bracket 2 includes a limiting shell 201 and a connecting collar 204. The inner walls of the three limiting shells 201 are provided with support legs 202. The extension ends of the three limiting shells 201 are fixedly provided with sliders 203. The top ends of the three limiting shells 201 are fixedly connected with collars 204. The sliders 203 are slidably arranged in the groove structure on both sides of the slotted inner wall of the support column 1. The top surface of the inner wall of the three limiting shells 201 is provided with protrusions that cooperate with the protrusions on one side of the top of the three support legs 202 to limit and prevent the support legs 202 from opening and closing too much.

[0028] Specifically, after transporting the entire device to the target deployment area, the extended conical section at the lower end of the support column 1 is first vertically inserted into the underground soil. Since the length of this extended section is significantly greater than the length of the support leg 202 of the triangular limiting bracket 2, initial vertical orientation and simple stable positioning of the device can be achieved after insertion, providing a certain degree of anti-tilting capability and a stable foundation for the subsequent deployment of the triangular limiting bracket 2. Subsequently, the deployment of the triangular limiting bracket 2 is carried out. Through multiple longitudinal slots on the side wall of the support column 1, the sliders 203 on the three limiting shells 201 in the triangular limiting bracket 2 can slide up and down in the sliding groove structure. The operator manually presses down the connecting collar 204, causing the three limiting shells 201 connected to it to move downwards synchronously, thereby driving the three sliders 203 to slide to the set position in the corresponding sliding groove. When the sliders 203 slide to the set position, they contact the three limiting blocks 302 located in the limiting guide groove. Under pressure, the slider 203 slides and contracts within the guide groove, causing the support rod 303 to move backward. During the movement of the rod, the connected spring 304 is compressed. When the slider 203 continues to slide to the final positioning point, the spring 304 releases its restoring force, causing the support rod 303 to return to its original position, thereby causing the limiting block 302 to extend again, locking the slider 203 at the current height position, and realizing the stable deployment of the triangular limiting bracket 2. At this time, the support leg 202 automatically or manually rotates outward or folds out from the limiting shell 201. After reaching the preset angle, the protruding structure at its top contacts the limiting protruding block structure on the top surface of the inner wall of the limiting shell 201, forming a reliable limit to prevent the support leg 202 from becoming too large and causing instability. The three support legs 202 are arranged in an equal angle direction. With the ground-inserted support column 1 positioning structure, the overall wind resistance, overturning resistance and ground stability of the device can be effectively improved. It is particularly suitable for rapid deployment in complex terrain, soft ground or forest environments without attachments.

[0029] To achieve the above-mentioned utility model objectives, such as Figure 1-7As shown, this utility model provides a forest fire monitoring device. A limiting device 3 is rotatably connected to the center point of the top of the extension column 101. The limiting device 3 includes a rotating shaft 301, with three supporting rods 303 spaced 120 degrees apart circumferentially on the rotating shaft 301. A limiting block 302 is fixedly installed on one side of each of the three supporting rods 303. A baffle 103 is fixedly installed on the top surface of the extension column 101 near the three supporting rods 303, and a spring 304 is fixedly installed on one side of each of the three baffles 103. All three springs 304 are fixedly connected to the three supporting rods 303. On one side of the protective box 4, a storage battery 401 is fixedly installed on one side of the inner wall. A smoke sensor 7 is fixedly installed in the center of the top surface of the protective box 4. A temperature sensor 6 is fixedly installed on one side of the smoke sensor 7, and a humidity sensor 8 is fixedly installed on the other side of the smoke sensor 7. A limiting device 3 is installed on the inner wall of the support column 1. Three limiting blocks 302 are slidably fitted in the limiting guide groove provided on the lower end of the slotted inner wall of the support column 1. The three supporting connecting rods 303 extend outward through the guide hole opened on the side wall of the support column 1 near the end of the limiting block 302.

[0030] Specifically, the solar panel 9 is supported and fixed by multiple support rods 10 set on the top surface of the protective box 4. Its output end is electrically connected to the energy storage battery 401 fixedly installed on the inner wall of the protective box 4, providing a continuous and stable power supply for the core monitoring components inside the device, including the thermal imager 5, smoke sensor 7, temperature sensor 6, and humidity sensor 8. This ensures that the system can operate 24 hours a day, 365 days a year, and also has a certain rain protection function. The aforementioned thermal imager 5, smoke sensor 7, temperature sensor 6, and humidity sensor 8 all have good waterproof and dustproof capabilities, and can adapt to rain and dust pollution in the field deployment environment, improving the reliability and durability of the system. When the device is in working condition, the thermal imager 5 will continuously perform infrared imaging scanning on the target area to identify areas with abnormal temperature rises in the forest area, and realize early detection of fire signs. The smoke sensor 7 monitors the concentration changes of combustible particulate matter in the air in real time, and, combined with the environmental parameters collected by the temperature sensor 6 and humidity sensor 8, constructs a multi-source data cross-analysis mechanism, thereby improving the environmental monitoring capabilities. Even slight changes in environmental parameters can trigger a comprehensive assessment of potential fire hazards, significantly improving the accuracy and response speed of the forest fire early warning system. When the device needs to be removed or relocated on-site, the operator can manually push the support rod 303 located outside the guide hole on the side wall of the support column 1, thereby rotating the shaft 301 and causing the three support rods 303 to retract inward simultaneously. This also drives the three corresponding limit blocks 302 to slide inward along the limit guide groove, releasing the limit on the slider 203 in the triangular limit bracket 2. After the limit is released, the operator can move upward... Pushing the connecting collar 204 causes the triangular limiting bracket 2 to move upward as a whole. The slider 203 slides upward along the groove on the side wall of the support column 1 and enters the upper limiting device 3 for further limiting. At the same time, the three support legs 202 are manually folded and gathered into the limiting shell 201 in sequence, completing the compact storage of the entire device. Through the above operation process, the device can be quickly folded and conveniently gathered, with good mobility and reusability. It is suitable for temporary deployment or long-term fixed monitoring needs in various outdoor environments such as forests, grasslands, and open areas under forests.

[0031] The solar panel of this invention converts solar energy into direct current; secondly, the voltage and current are dynamically adjusted through a voltage regulator circuit or a maximum power point tracking (MPPT) controller; then, the adjusted electrical energy is input into the energy storage battery via a charging management module (such as a boost or buck circuit); finally, the battery uses a built-in protection circuit to achieve overvoltage, overcharge, and reverse connection protection, thereby ensuring safe and reliable energy storage. The above-mentioned principles of solar energy regulation and energy storage conversion are well known to those skilled in the art, therefore, this application will not elaborate on its circuit structure and control logic.

[0032] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
