Forest fire control helicopter for spraying water by using mechanical power

Abstract

The invention discloses a forest fire control helicopter for spraying water by using mechanical power. The forest fire control helicopter comprises a body (1), a water pump belt disc (3), a belt disc gear (4), a sling rotary disc (10) and a fire pump water valve (21), wherein the lower part of a front cabin of the body (1) is provided with a gear box; the water pump belt disc (3) is movably sleeved on a power shaft (2) and the belt disc gear (4) is hinged with a fire pump (20) to rotate and operate; a bevel gear at the lower end of the power shaft (2) is hinged with a bevel gear of the power shaft of the gear box; the bevel gear (8) on a driven shaft (7) is rotated through the gear and a back gear; and the bevel gear (8) is hinged with a sling bevel gear (9), the sling rotary disc (10) is operated, and a water tank (22) is lifted through a wire rope (12) and positioned through an automatic buckle (12). The technology is scientific in design and unique in conception and is an ideal forest and high-level water spray fire extinguishing helicopter.

Description

(1) Technical field [0001] The invention relates to an improved invention of a multifunctional forest fire-fighting water spray helicopter. (2) Background technology [0002] In the prior art, known forest fires on the market have used water sources to pour into the fire-fighting helicopter in the center of the fire at one time to achieve the fire-extinguishing effect. The birth of this technology has broken through forest fires and has advanced special-purpose forest fire-fighting helicopters. After analysis: the one-time irrigation method to achieve the effect of forest fire extinguishing has the following problems: 1. Forest mountainous areas are generally located in undulating terrain, especially the terrain with large slopes. The one-time irrigation seems to be poured into the ground like a water column to form a fire The direction of spreading is opposite: a. The flame spreads and burns upwards; b. The water source for irrigation will flow down along the slope. 2. The...

AI Technical Summary

Problems solved by technology

After analysis: the one-time irrigation method to achieve the effect of forest fire extinguishing has the following problems: 1. Forest mountainous areas are generally located in undulating terrain, especially the terrain with large slopes. The one-time irrigation seems to be poured into the ground like a water column to form a fire The opposite direction of spreading: a. The momentum of the flame spreads and burns upwards; b. The water source for irrigation will flow down along the slope

2. The characteristics of forest fires are that the flames burn violently upwards and spread quickly, and the area is large. Especially the small trees that have died for a long time, dry bark, branches, etc. are the best materials for burning. Using one-time irrigation to extinguish the fire will lost effect

Therefore, the one-time irrigation method cannot achieve the best fire extinguishing effect.
