[0002] Forest fire is one of the eight major natural disasters in the world. The continuous burning of forest fire seriously threatens life, property and ecological security. It has the characteristics of wide occurrence, strong suddenness, great destructiveness, and difficult handling and extinguishing. The solidified foam fire extinguishing agent is a mixture of foam stock, surfactant, and foaming agent. It is an environmentally friendly and efficient adhesive solidified foam fire extinguishing agent used to solve the problems of high three-dimensional combustion intensity of forest fire, difficult water resources for fire extinguishing, difficult to open rapid fire barrier isolation belts, and poor equipment mobility. It can play a good fire extinguishing effect on forest fires. However, the current use of solidified foam fire extinguishing agents is to build factories near the forest. If a fire occurs, a large amount of solidified foam is produced in the factory, and then large equipment such as tank trucks are used to transport the prepared solidified foam fire extinguishing agent to the required fire extinguishing location for large-scale fire extinguishing; currently this method is mainly suitable for large-scale forest fire extinguishing; and in the early stage of a forest fire, if the forest ranger discovers the fire, and then prepares it in the above-mentioned factory, it will delay the fire extinguishing time.

[0003] Therefore, how to provide a new device that can be easily moved to the fire extinguishing area in the early stage of a forest fire, and quickly spray solidified foam fire extinguishing agent to fire sources at different locations to control and extinguish the early fire, thereby effectively improving the forest fire extinguishing effect, is the technical problem that the utility model needs to solve.

[0027] The liftable spraying platform comprises a spraying platform and a plurality of electric telescopic rods 4, the spraying platform is located above the crawler vehicle 1, the plurality of electric telescopic rods 4 are parallel to each other and are located between the spraying platform and the crawler vehicle 1, and the lower end of each electric telescopic rod 4 is fixedly connected to the upper part of the crawler vehicle 1, and the lower end is fixedly connected to the lower part of the spraying platform, and is used to drive the spraying platform to move up and down along the axis of the electric telescopic rod 4;

[0028] The circular slide 7 is fixed on the upper part of the spraying platform, and a plurality of electric sliders 8 are installed on the circular slide 7. A plurality of nozzles 9 are installed on each electric slider 8 one by one, so that each nozzle 9 can move along the circular track 7 to adjust the spraying direction; the water pump 6 is installed on the solidified foam stock tank 2, and the inlet of the water pump 6 is connected to the inside of the solidified foam stock tank 2, and the outlet of the water pump 6 is connected to the inlet of each nozzle 9 through a plurality of hoses 5, which is used to pump the solidified foam fire extinguishing agent from the solidified foam stock tank 2 to each nozzle 9 and then spray it out; the nozzle 9 is a flat nozzle with a vertically adjustable angle, and the vertical adjustment angle is 0°~60°. With this existing structure, the nozzle 9 has a larger spray angle in the vertical direction to meet the required requirements; an electric valve is installed at the inlet of the nozzle, and the electric valve is connected to the signal receiver 10 to control the connection state between the nozzle 9 and the water pump 6. This arrangement enables each nozzle 9 to be independently controlled to open and close, and under the premise that the power of the water pump 6 is not increased, if it is necessary to increase the spray flow rate of some nozzles 9, the electric valves of other nozzles 9 can be closed. In this way, the solidified foam fire extinguishing agent pumped by the water pump 9 is only sprayed through the nozzles 9 whose electric valves are not closed, thereby increasing the spray flow rate of the required nozzles 9.

[0029] The remote control terminal communicates wirelessly with the signal receiver 10, and is used to send control instructions to the signal receiver 10; the signal receiver 10 is installed above the spraying platform through a support rod, and the signal receiver 10 is connected to each electric telescopic rod 4, each electric slider 8, water pump 6 and tracked vehicle 1 through a data line, and is used to receive control instructions and control the electric telescopic rod 4, electric slider 8, water pump 6 and tracked vehicle 1; the explosion-proof battery supplies power to the signal receiver 10, the electric telescopic rod 4, the electric slider 8 and the water pump 6. The explosion-proof battery can be installed on the spraying platform or the curing foam stock tank 2 as needed;

[0030] As an improvement of the utility model, there are four electric sliders 8 and nozzles 9, and four evenly distributed limit blocks are installed on the circular slide rail 7. An electric slider 8 and nozzle 9 are installed on the circular slide rail 7 between two adjacent limit blocks, so that each electric slider 8 can only move between two adjacent limit blocks. In this way, the moving position of each electric slider 8 on the circular slide rail 7 can be controlled to prevent mutual collision during control.

[0031] As another improvement of the present invention, the solidified foam stock tank 2 is provided with a stirring blade 11 such as Figure 3 As shown, a motor is installed at the bottom of the solidified foam stock tank 2, the rotating shaft of the motor extends into the solidified foam stock tank 2 and is coaxially connected to the stirring blade 11, the motor is connected to the signal receiver 10 and powered by an explosion-proof battery, and is used to stir the solidified foam fire extinguishing agent in the solidified foam stock tank 2. By setting the stirring blade, the solidified foam fire extinguishing agent can be stirred according to the transportation time to ensure its foaming effect.

[0032] The above-mentioned crawler vehicle 1, curing foam liquid tank 2, electric telescopic rod 4, explosion-proof battery, water pump 6, electric slider 8, nozzle 9, signal receiver 10 and remote control terminal are all existing equipment or components, which can be directly purchased on the market. The process in which the remote control terminal sends control instructions to the signal receiver 10 to control the crawler vehicle 1, curing foam liquid tank 2, electric telescopic rod 4, explosion-proof battery, water pump 6, electric slider 8 and nozzle 9 is an existing control process. The utility model only uses the existing control power supply and does not improve the program and communication.

[0033] First, a solidified foam fire extinguishing agent is prepared by mixing a foam stock solution, a surfactant and a foaming agent, and the solidified foam fire extinguishing agent is placed in a solidified foam stock solution tank 2. Then, the staff begins to patrol the forest. During this process, if a fire is found somewhere in the forest, the staff will notify the personnel near the tracked vehicle 1 to control the tracked vehicle 1 to move to the designated position through the remote control terminal. According to the location of the fire source, the staff first manually adjusts the spray angle of the sprinkler 9 in the vertical direction, and then sends a control instruction through the remote control terminal. After receiving the instruction, the signal receiver 10 controls each electric telescopic rod 4 to telescopically adjust the height of the spraying platform to the desired position, and then controls each electric slider 8 to move to the desired position on the circular slide rail 7 and stop, so as to adjust the spray angle of the sprinkler in the horizontal direction, and finally starts the water pump. 6. The solidified foam fire extinguishing agent is pumped from the solidified foam stock tank 2 to each nozzle 9 and then sprayed out, thereby forming a fire isolation zone with a width of 20 to 30 meters on the unburned forest vegetation in the fire extinguishing area, and quickly extinguishing the fire source by lowering the temperature and isolating oxygen; during the spraying process, the horizontal angle of each nozzle can be adjusted to adapt to the development of the fire by adjusting the moving position of the electric slider 8 according to the fire situation; if the fire situation is more serious and the solidified foam fire extinguishing agent sprayed by the water pump 6 at the maximum power cannot achieve the desired effect, the electric valves of some nozzles 9 can be closed, and the remaining nozzles can be aimed at the fire source. At this time, the spray flow rate and flow rate of the solidified foam fire extinguishing agent of the remaining nozzles can be increased, so that the spraying of the solidified foam fire extinguishing agent is more concentrated, thereby improving the fire extinguishing effect on the fire source.

[0034] The above is only a preferred embodiment of the present invention.
