[0002] Currently, most wind-powered fire extinguishers on the market are small, including handheld, backpack, and some modified from small robots. They require manual carrying to approach the fire source or placing the equipment next to the fire source to carry out fire extinguishing operations, thus putting fire extinguishing personnel or equipment in danger. In addition, this type of equipment has a small air volume and low air pressure, resulting in low fire extinguishing efficiency. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0026] Reference Figure 1 This onboard large-scale wind-powered fire extinguishing device is mounted on the stick C of the excavator's working device via a pin shaft. It consists of two main parts: an air supply system A and an installation, airflow guiding, and heat insulation system B. For example... Figures 2-3 As shown, the air supply system consists of a centrifugal fan 1, shaft 2, bearing 3, coupling 4, hydraulic motor 5, fan bracket 6, motor bracket 7, first rigid pipe 8, second rigid pipe 9, connector 10, hose 11, bolts 12, etc. The centrifugal fan 1 includes two symmetrical fan brackets 6, with an impeller and shaft 2 connected between them. Bearing 3 is also mounted on shaft 2. One end of the centrifugal fan 1 is fixed to the motor bracket 7 by bolts 12. The hydraulic motor 5 is connected to the motor bracket 7, and the hydraulic motor 5 is connected to the hose 11 via connector 10. The other end of the hose 11 is sequentially connected to the first rigid pipe 8 and the second rigid pipe 9, with the hose 11 connected to the second rigid pipe 9. Shaft 2 passes through the motor bracket 7 and is connected to the hydraulic motor 5 via coupling 4. The assembly relationship of the centrifugal fan is as follows. Figure 4 As shown.

[0027] like Figure 5 Centrifugal fan 1 is an integrally welded centrifugal fan. This fan transports gas by the centrifugal force generated by the rotation of the impeller. The gas enters the impeller axially and is thrown out of the impeller radially under the action of the high-speed rotating impeller. After entering the air guide shroud, it flows out tangentially and is discharged through the air outlet. Compared with axial flow fans, centrifugal fans have higher air pressure and less requirements on the medium flowing through them.

[0028] Reference Figure 6The installation and heat insulation system B consists of a heat duct 13, an air outlet 14, a heat duct bracket 15, a connecting support 16, a dustproof net 17, a motor cover 18, and heat insulation sponge. The front end of the heat duct 13 is the air outlet 14, and its rear end and two sides are clamped by the heat duct bracket 15. The heat duct bracket 15 is formed by parallel left and right side frames and a bottom side plate. One side frame is connected to the dustproof net 17, the other side frame is connected to the motor cover 18, and the bottom side plate is connected to the connecting support 16. The heat duct 13 is shaped like a snail shell, and the air outlet is triangular. Heat insulation sponge is installed inside the motor cover 18. The heat duct 13, air outlet 14, heat duct bracket 15, connecting support 16, dustproof net 17, and motor cover 18 are connected by bolts. This connection method has the following advantages:

[0029] 1) It is convenient to replace the air outlets of different shapes (sizes) to adapt to the needs of different scenarios;

[0030] 2) Facilitates cleaning of the dust filter (air inlet) and ensures unobstructed airflow;

[0031] 3) Different sizes of working devices can be matched by changing parts.

[0032] Principle Explanation: The engine drives the main pump to rotate, generating pressurized oil. This pressurized oil passes through the hydraulic main valve and then through pipelines to the end of the working device (this action is controlled by the control device in the cab). Figure 7 As shown, pressurized oil enters motor 5 through pipelines, driving the motor to rotate. The motor then drives centrifugal fan 1 to rotate via coupling 3, drawing air in through dust filter 17 and discharging it through outlet 14, forming a high-flow-rate, high-pressure airflow, thereby enabling long-distance firefighting operations. Figure 8 As shown.

[0033] Operation Description: By operating the boom cylinder and stick cylinder, the boom and stick are moved, adjusting the extension distance and position of the onboard large-scale wind-powered fire extinguishing device. This keeps the excavator and operator away from the fire source. Then, by operating the bucket cylinder, the angle of the onboard large-scale wind-powered fire extinguishing device's outlet relative to the fire source is adjusted, thus achieving long-distance fire extinguishing operations. Figure 9 As shown.

[0034] This device creates a new wind-powered fire extinguishing system by changing the installation method of the centrifugal fan or the structure of the air guide hood and air outlet; it also changes the driving method of the centrifugal fan, replacing the hydraulic motor with an electric motor; in addition to fire extinguishing operations, this device can also be used for snow blowing, dust removal, and cleaning operations.

[0035] The present invention provides a detailed description of an airborne large-scale wind-powered fire extinguishing device. Specific examples have been used to illustrate the structure and working principle of the present invention. The descriptions of the embodiments are merely for the purpose of helping to understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
