[0002] Forest fire refers to a forest fire that loses human control, spreads and expands freely in the forest, and causes certain harm and losses to the forest, forest ecosystem and human beings. It is a disaster with strong suddenness, great destructiveness and difficult handling and rescue. Forest fire not only burns large tracts of forests and harms animals in the forest, but also reduces the reproductive capacity of the forest, causes soil impoverishment and destroys forest water conservation, and even causes the ecological environment to lose balance. Forest fire prevention workers are responsible for protecting forest resources, preventing and fighting forest fires. In field operations such as forest fire prevention, workers usually need to carry a large number of tools, equipment and materials to deal with various emergencies. Traditional backpacks have a single function and can only meet basic loading needs, and cannot provide convenient operation assistance for forest fire prevention workers.

In addition, any methods and materials similar or equivalent to those described herein may be applied to the present invention. The preferred implementation methods and materials described herein are for demonstration purposes only and are not intended to limit the content of this application.

[0030] The experimental methods in the following examples are conventional methods unless otherwise specified, and the experimental materials used in the following examples are purchased from commercial channels unless otherwise specified.

[0031] Reference Figure 1-4The present invention provides an embodiment: a propaganda and shouting multifunctional backpack, including a backpack body 1, a left ear bag 2 is arranged on one side of the backpack body 1, and a right ear bag 3 is arranged on one side of the left ear bag 2 of the backpack body 1. The left ear bag 2 can be used to place items such as a kettle and a map to provide necessary supplies and navigation guidance for workers when working in the field. The upper part of the left ear bag 2 is provided with a charging port 4, which can charge the speaker, and can also reversely charge a mobile phone or a walkie-talkie through the speaker, and has the function of plugging in a fire lamp, etc., which greatly facilitates the work and warning needs of the workers at night or in dim light environments. The right ear bag 3 is equipped with a retractable military shovel 5, and the back of the backpack body 1 is provided with two back shoulders 6. The bottom of the back shoulders 6 is provided with open ear bags 7 that pass through the bottom left and right. The open ear bags 7 are equipped with a No. 2 tool 8. The military shovel 5 and the No. 2 tool 8 can be seamlessly connected, so that they can be used together to effectively extinguish fires. The total length of the No. 2 tool 8 is 1.2 meters, and the No. 2 tool 8 can be retracted to 20 centimeters. The military shovel 5 has multifunctional uses such as chopping, sawing, shoveling, making tools, and field operations. For example, when opening up a fire isolation zone, the chopping and sawing functions of the military shovel 5 can quickly clear vegetation, and when encountering a small gully that needs to be filled, the shoveling function can come in handy. The shoulder strap 6 is provided with an adjustment component 9, through which the length of the shoulder strap 6 can be adjusted to meet the carrying needs of workers of different body shapes, ensuring that the backpack can fit the body closely and reduce shoulder pressure. The shoulder strap 6 is provided with a waist belt 10, which greatly increases the comfort of outdoor carrying and outdoor operations. The waist belt 10 can transfer part of the weight of the backpack to the waist, utilize the stronger load-bearing capacity of the waist, and disperse the overall carrying pressure. A small ear bag 11 is provided on each shoulder strap 6, which can be used to place some commonly used small tools or personal items, such as first aid medicines, compasses, etc., for easy access at any time. An outdoor speaker 12 is arranged at the bottom of the inner shell of the backpack body 1. The power of the outdoor speaker 12 is 10W. The outdoor speaker 12 is equipped with a memory card 13, Bluetooth 14 and a microphone 15. The microphone 15 is placed in one of the small ear bags 11. Shouting can be carried out through the outdoor speaker 12, which plays an effective role in fire prevention publicity. The staff can record fire prevention publicity knowledge, fire warning information, etc. into the memory card 13 in advance, and play them in a loop during the patrol; they can also connect to a mobile phone through Bluetooth 14 to play the latest fire prevention notice in real time or receive instructions from superiors. The volume of the upper part of the inner shell of the backpack body 1 is 50 liters, and the clothes of forest fire fighters, fire bombs and other tools can be placed on the inner shell.

[0032] The backpack body 1 is made of eye-catching red aramid fabric with good abrasion resistance, strong friction resistance and color fastness, and is reinforced and sewn to be waterproof, dustproof and fireproof. A sponge is arranged on the back of the backpack body 1, and a metal bracket is arranged inside the backpack body 1 to ensure that the waist is protected when carried and is not easily strained.

[0033] Working principle: Before entering the forest fire prevention area to perform tasks, the staff first adjusts the adjustment component 9 on the shoulder 6 according to their own body shape to make the shoulder 6 length suitable, and then tightens the waist belt 10 to adjust the backpack to the most comfortable carrying state. During the journey, daily supplies and navigation tools such as water bottles and maps are placed in the left ear bag 2 for easy access at any time; when fire prevention propaganda is needed, take out the microphone 15 from the small ear bag 11 where the microphone 15 is placed, use the outdoor speaker 12 at the bottom of the backpack liner, play the pre-recorded propaganda content through the memory card 13, or connect the mobile phone through Bluetooth 14 to play the latest information in real time. The 10W power of the speaker ensures that the sound can be effectively transmitted in the open forest. Once a fire hazard is found, quickly take out the retractable military shovel 5 from the right ear bag 3, pull out the second tool 8 from the open ear bag 7, adjust the second tool 8 to a suitable length according to the fire situation, and use the seamless docking function of the military shovel 5 and the second tool 8 to coordinate firefighting operations. During this period, if the power of the mobile phone or walkie-talkie is insufficient, it can be charged through the charging port 4 on the left ear bag 2 to ensure smooth communication. During the whole process, the backpack, with the excellent characteristics of its aramid fabric, resists external friction, water, fire, and dust. The internal metal bracket and the back sponge continue to provide waist protection and comfortable carrying experience for the staff, fully meeting the needs of forest fire prevention work.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0035] The present invention and its implementation methods are described above, which is not restrictive. The drawings are only one of the implementation methods of the present invention, and the actual application is not limited thereto.
