Description

Technical Field

[0001] The utility model relates to the technical field of forest fire prevention, in particular to a forest fire prevention early warning device. Background Art

[0002] Forest fire is the most dangerous enemy of forests and the most terrible disaster in forestry. It will bring the most harmful and devastating consequences to forests. Forest fire not only burns large tracts of forests and harms animals in the forests, but also reduces the reproductive capacity of forests, causes soil impoverishment, destroys forest water conservation, and even causes the ecological environment to lose balance.

[0003] The utility model with publication number CN218038212U discloses an early warning device for forest fire prevention. The device controls the rotation of a servo motor through a single-chip microcomputer, thereby driving the rotation of a linkage turntable to make the screw thread linked, so that the second column moves up and down in the first column, so that the staff can remotely control the overall height of the device; and by providing a temperature sensor and a smoke sensor, the temperature and smoke around the device are monitored by the temperature sensor and the smoke sensor respectively, thereby improving its early warning efficiency; and by providing a photoelectric sensor, the photoelectric sensor enables the stepping motor and the electric hydraulic push rod inside the electric control box to work automatically, thereby adjusting the angle of the solar panel, so that the device can absorb solar energy to the greatest extent.

[0004] However, despite the significant progress made in improving early warning efficiency, the scope of the device is still limited to monitoring and early warning, and has not been able to cross over to direct firefighting operations. Specifically, the system lacks built-in direct firefighting facilities, such as water spray systems, dry powder or carbon dioxide release devices, which means that in the face of sudden fires, its role is limited to timely alarms, but it cannot take any substantial physical intervention measures to directly suppress or extinguish the fire source. This is particularly disadvantageous for forest areas far away from cities, remote or inconveniently located, because even if the warning is timely, the arrival of firefighting forces and the launch of firefighting operations may still be delayed due to geographical restrictions, missing the best time to control the spread of the fire. In view of this, how to integrate or develop a device that can respond immediately and implement preliminary firefighting operations based on the existing early warning technology has become a technical problem that needs to be solved urgently, which is of great significance for building a more complete and efficient forest fire prevention and control system. Utility Model Content

[0005] The purpose of the utility model is to provide a forest fire warning device to solve the problem raised in the above background technology that most of the current forest fire warning devices lack the function of direct preliminary fire extinguishing, and can only alarm but cannot take physical intervention in the face of fire.

[0008] Preferably, a linkage rod is connected between the nozzle bracket and the push rod, and both ends of the linkage rod are hinged to the connection between the nozzle bracket and the push rod through a pin shaft.

[0009] Preferably, the upper and lower ends of the inner side of the U-shaped frame are both penetrated with adjusting studs through a threaded structure, and a sleeve is fixed to one end of the adjusting stud located at the inner end of the U-shaped frame, and the upper and lower ends of the inner side of the dry powder tank are both provided with a clamping column that matches the sleeve structure.

[0010] Preferably, a positioning column inserted into the bottom end of the U-shaped frame is fixed to the outer side of the bottom end of the dry powder tank, and the bottom end of the U-shaped frame is provided with an arc-shaped opening matched with the positioning column structure.

[0011] Preferably, the bottom end of the U-shaped frame is rotatably connected to a buckle, and the outer end of the buckle is connected to a positioning screw via a threaded structure, and the outer end of the positioning column is provided with a threaded hole that matches the positioning screw structure at the outer end of the buckle.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the forest fire warning device can not only quickly sound an alarm at the early stage of a fire by integrating the warning and initial fire extinguishing functions, but also take immediate and effective physical intervention measures, significantly shortening the response time, and is particularly suitable for remote or inconveniently accessible forest areas, effectively reducing fire losses. The device is provided with a dry powder tank installed through a U-shaped frame on the support rod body. Once the fire is confirmed, the electronic control system directs the cylinder to work, drives the push rod to open the plugging sleeve, instantly opens the dry powder release channel, and implements the initial fire extinguishing operation. The water spray mechanism equipped on the outside of the U-shaped frame serves as an auxiliary fire extinguishing facility, which releases water mist under suitable conditions, thereby enhancing the fire extinguishing effect and building a comprehensive fire prevention system that can monitor in real time and intervene in real time.

The early warning mechanism on the upper part of the support rod 1 of this structure integrates an electric control box, a surveillance camera and a solar panel to monitor the forest area and power supply, and realize early warning of fire. In addition, a dry powder tank 3 is installed on the support rod 1 through a U-shaped frame 2 to store the fire extinguishing medium. The powder outlet 4 of the dry powder tank 3 is ready to release the fire extinguishing agent. When the system detects a fire, the electric control system will activate the cylinder 8 to drive the push rod 7 to move and push the blocking sleeve 6, and the dry powder can be quickly sprayed out through the powder outlet 4 for initial fire extinguishing. At the same time, the water spraying mechanism arranged outside the U-shaped frame 2 is used as an auxiliary fire extinguishing means. It can provide additional water mist fire extinguishing support when the fire permits, forming a comprehensive fire prevention mechanism, so that the device realizes the functions of fire monitoring and preliminary intervention, and improves the efficiency and response of forest fire prevention. Speed, suitable for remote or inaccessible forest areas, effectively reducing fire losses, the water spraying mechanism at the top of the U-shaped frame 2 includes a water tank 9, a high-pressure pump 10, a high-pressure nozzle 11 and a nozzle bracket 12, the water tank 9 and the high-pressure pump 10 are both mounted on the top of the U-shaped frame 2, the nozzle bracket 12 is fixed to the outside of the top of the U-shaped frame 2, the high-pressure nozzle 11 is installed on the nozzle bracket 12 and is connected to the liquid outlet end of the high-pressure pump 10 through a hose, the liquid suction end of the high-pressure pump 10 is connected to the bottom end of the water tank 9, the water tank 9 and the high-pressure pump 10 of this structure are placed together on the top of the U-shaped frame 2, ensuring sufficient water source and pressure supply, when the high-pressure pump 10 is started, it absorbs water from the bottom of the water tank 9 through its liquid suction end, and then pressurizes until the high-pressure water flows through the hose. As for the high-pressure nozzle 11, the high-pressure nozzle 11 enables water to be sprayed forcefully in the form of atomization, covering a wider area, effectively cooling down and preventing the spread of fire. The bottom end of the nozzle bracket 12 is movably connected to the top of the U-shaped frame 2 through a hinge seat. A linkage rod 13 is connected between the nozzle bracket 12 and the push rod 7, and both ends of the linkage rod 13 are hinged to the connection between the nozzle bracket 12 and the push rod 7 through a pin shaft. When the push rod 7 of this structure is pushed horizontally, it will synchronously drive the nozzle bracket 12 through the linkage rod 13 to produce linkage. When the nozzle bracket 12 is subjected to force, it can be tilted and moved to different angles at the top of the U-shaped frame 2 to increase the spraying range of the high-pressure nozzle 11, so as to achieve a better fire extinguishing effect. The upper and lower ends of the inner side of the U-shaped frame 2 are interspersed with adjustment studs 15 through a threaded structure.The adjusting stud 15 is located at one end of the inner end of the U-shaped frame 2 and is fixed with a sleeve 16, and the upper and lower ends of the inner side of the dry powder tank 3 are provided with a clamping column 14 that matches the structure of the clamping column 16. The adjusting stud 15 of this structure can drive the clamping column 16 to move up and down by rotating at the upper and lower ends of the U-shaped frame 2. When the clamping column 16 moves, the dry powder tank 3 can be positioned by engaging the clamping column 14, which makes it convenient for the dry powder tank 3 to be disassembled and replaced inside the U-shaped frame 2. The outer side of the bottom end of the dry powder tank 3 is welded and fixed with a positioning column 5 inserted in the bottom end of the U-shaped frame 2, and the bottom end of the U-shaped frame 2 is provided with an arc-shaped opening that matches the structure of the positioning column 5. The bottom end of the U-shaped frame 2 is rotatably connected with a buckle 17 through a turn pin, and the outer end of the buckle 17 is a bent structure and is threaded. The structure is connected with a positioning screw, and the outer end of the positioning column 5 is provided with a threaded hole that matches the positioning screw structure at the outer end of the buckle 17. The positioning column 5 of this structure can be moved in the arc-shaped opening at the bottom end of the U-shaped frame 2 to achieve the adjustment of the dry powder tank 3 in the horizontal direction, and the buckle 17 can be rotated to use the positioning screw at the outer end to align with the threaded hole at the outer end of the positioning column 5. This design allows the operator to preset the direction of the dry powder tank 3 by adjusting the position of the positioning column 5, such as aligning the powder outlet 4 with the area in the forest most prone to fire, and firmly locking the dry powder tank 3 at the set optimal orientation angle, which is conducive to ensuring that the dry powder fire extinguishing agent can be quickly and accurately thrown at the fire source in an emergency, greatly enhancing the application efficiency of the device.

[0019] Working principle: When using the forest fire warning device, first install the dry powder tank 3 on the support rod body 1 through the U-shaped frame 2 to store the fire extinguishing medium. During the installation of the dry powder tank 3, the two adjusting studs 15 are rotated respectively. When the adjusting studs 15 are rotated at the upper and lower ends of the U-shaped frame 2, the clamping sleeve 16 will be driven to move up and down until the clamping sleeve 16 completes the positioning of the dry powder tank 3 by engaging the outside of the clamping column 14. During the installation of the dry powder tank 3, the positioning column 5 is moved in the arc-shaped opening at the bottom end of the U-shaped frame 2 until the dry powder tank 3 aligns the powder outlet 4 with a suitable angle position, and then the buckle 17 is rotated to use the positioning screw at the outer end to align and connect with the threaded hole at the outer end of the positioning column 5 to limit the position of the dry powder tank 3. When the device is in use, the surveillance camera continuously monitors the forest area, and the electronic control box uses solar panels to power the entire system. Once a fire occurs, the electronic control box immediately instructs the cylinder 8 to work, and the push rod 7 is pushed out, releasing the blocking of the blocking sleeve 6 on the powder outlet 4, and the fire extinguishing agent in the dry powder tank 3 is immediately sprayed toward the fire source through the powder outlet 4. At the same time, the water spraying mechanism on the top of the U-shaped frame 2 responds, and the high-pressure pump 10 draws water from the bottom of the water tank 9 and pressurizes it. The high-pressure water flow is sent to the high-pressure nozzle 11 along the hose and converted into water mist spraying to assist in fire extinguishing. The lateral movement of the push rod 7 is linked to the nozzle bracket 12, and the high-pressure nozzle 11 is adjusted in angle through the linkage rod 13 to optimize the fire extinguishing coverage, thereby completing a series of tasks.
