With the modern development, although the emergency rescue equipment develops rapidly, the corresponding emergency rescue material delivery means is difficult to meet the requirements, particularly, the emergency rescue equipment has defects in disaster rescue in areas with underdeveloped traffic and fire rescue in high-rise buildings, and the defects are mainly reflected in two aspects of delivery modes and delivery equipment. At present, two modes are mainly adopted for delivering fire rescue goods and materials in disaster areas with underdeveloped traffic and high-rise buildings, wherein the first mode is a solid rocket type emergency rescue delivery device, and the second mode is a high-pressure gas cylinder as a power source for delivering emergency goods and materials. Although the former has the advantages of large power, strong carrying capacity and the like, the solid rocket as an initiating explosive device with high risk is harsh on storage and use conditions, and most of the existing emergency rescue departments do not have the site and the conditions for storing the initiating explosive device. Although the latter is relatively loose in storage and use conditions, the weight of delivered materials is in direct proportion to the projection recoil and the weight of the projection device, so that the volume and the required gas quantity of the high-pressure gas cylinder are larger along with the increase of the weight of the delivered materials, and the requirement on a carrying platform is higher, therefore, the high-pressure gas cylinder can only be used for delivering rescue materials with smaller quality due to the limitations of the current carrying platform technology, cost and the like. Moreover, the high-pressure gas is easily affected by the environment, and the environment is often complicated and changeable on the disaster site, so that the delivery mode by adopting the high-pressure gas cylinder has the defect that the delivery accuracy is difficult to guarantee. In addition, the two delivery modes also have the problem of short delivery distance, and the delivery requirements of the goods and materials cannot be met when the natural disasters such as forest fires, mountain disasters and the like needing long-distance emergency goods and materials delivery are faced. Therefore, a need is urgently needed to develop a novel delivery device which has lower requirements on storage and use conditions and carrying platforms, is more accurate in delivery and can effectively increase the delivery distance so as to meet the needs of fire rescue in disaster areas with underdeveloped traffic and urban high-rise buildings.
