A kind of solid projectile projectile and its projecting device and projecting method

Abstract

The invention relates to a solid projection bullet as well as a projection device and a delivery method thereof. The solid projection bullet is characterized by comprising a shell case; functional mediums such as gravels or / and soil are filled inside the shell case; and the shell case is made of fiber fabric, or the shell case is made of a flexible or rigid material which is easy to break due to collision. The solid projection bullet provided by the invention uses the gravels or / and the soil as the functional mediums. The solid projection bullets containing the different functional mediums can be selected. The solid projection bullet can be delivered by using a projection device, so that not only can the high firing range or the long-distance extinguishment be realized, but also a lot of the other functions can be realized, such as the solid projection bullet using the sand or the soil as the functional mediums can used for the high-firing range or the long-distance extinguishment in the fields, such as a high-rise building, a forest, an oil field and the like; and the solid projection bullet using the soil as the functional medium can realize the ecological recovery of a sandy land or relieve water and soil loss and the like of a barren mountain and a grass field.

Description

technical field [0001] The present invention relates to a kind of fire-fighting equipment, especially a kind of equipment that can be used for high-rise fire extinguishing, remote fire extinguishing in dangerous places, grasslands and forests, and an ecological protection equipment, especially equipment for water and soil conservation and vegetation restoration in arid areas, specifically The invention relates to a sand-stone or soil-based solid projectile, a long-distance projectile device and a projectile method thereof. Background technique [0002] In recent years, with the continuous and rapid development of the national economy, people's daily production and life have put forward higher and higher requirements for fire protection work, especially in places such as oil fields, oil depots, forests, grasslands, and high-rise buildings. , People are not easy to approach, therefore, long-distance fire extinguishing devices and high-range fire extinguishing devices have beco...

Problems solved by technology

[0006] On the other hand, with the worsening of global warming, many hillsides and grasslands in arid areas of our country are suffering from serious soil erosion and barrenness, unable to conserve forests and grasslands and absorb slow-release rainwater. As a result, rains cause floods and dry seasons are bare. The vegetation forest on the mountain must be supplemented with soil on the barren hill, but the existing transportation equipment does not have the road to the mountain, and it is basically a primitive method of transporting up the mountain by people on their shoulders. Ecological protection equipment and method for projecting soil and fertilizer to distant grasslands on hillsides
