Description

Crawler-type emergency rescue device for fire fighting

Technical Field

The invention belongs to the technical field of fire fighting facilities, and particularly relates to a crawler-type emergency rescue device for fire fighting.

Background

The emergency rescue mentioned above mainly includes emergency treatment of the barrage lake and fire fighting occasions, but is not limited by the aforementioned application occasions, such as emergency water supply for drought areas, emergency drainage for flood areas, and so on. In the case of the aforementioned barrier lakes, which are formed by blocking the river channels and storing a large amount of water due to debris flow caused by, for example, landslide, seasonal snow melting in snowy mountains, and a large amount of rainfall lasting in weather, immeasurable losses are caused if drainage and flood discharge to the barrier lakes are not timely and measures are not proper. At present, the drainage and flood discharge of barrier lakes still generally adopt the traditional blasting method, the manual flood discharge opening excavation method, the diversion pipe installation method and the like, and the method has the disadvantages of high danger and high flood discharge cost on one hand and the worry of causing secondary disasters on the other hand; in the case of the aforementioned fire fighting, in many fire sites, especially hazardous chemical fire sites, the speed of fire fighting and the effectiveness of the fire fighting are adversely affected by the difficulty, or even inability, of the fire fighting vehicle and the fire fighter to move too close together. It goes without saying that the above-mentioned technical problems are substantially solved if an emergency rescue facility is used which is capable of both autonomous walking and the formation of a powerful water column under remote control is used. The 'emergency rescue water cannon device' recommended by Chinese patent application publication No. CN110613908A has the following advantages: the automatic walking effect of the robot can be reflected, so that the requirement of no need of rescuers to follow the robot can be met; the water cannon can form a strong water column from water which is from the water diversion mechanism and reasonably pressurized by the pipeline, so that the requirements of effectively flushing a barrage lake to discharge flood and realizing the close fire extinguishing on the fire scene of the storage of dangerous chemicals and flammable and explosive articles which do not allow fire-fighting vehicles and fire fighters to be close to can be met; small volume, relatively simple and convenient structure, flexibility, economy, low price and strong practicability.

Although the above CN110613908A has many advantages, the following disadvantages still exist: firstly, although the equipped crawler traveling device can meet the flexible traveling requirement in disaster relief, the crawler traveling device is only limited to the required shuttle traveling in a disaster relief site, but is not suitable for long-distance walking from a public security fire department to a disaster place, so that a special 'fire fighting carrier loader' is required to carry the fire fighting carrier loader to a disaster relief site under normal conditions, when the emergency rescue water cannon device climbs to the fire fighting carrier loader (which is conventionally called as loading), it is often necessary to rest one end of a pair of guide plates on a "fire truck" by means of a pair of inclined guide plates, the other end is supported on the ground so as to make the emergency rescue water cannon device get on the vehicle slowly, which is slow and has a worry of losing safety, and is particularly inconvenient to be sent to complex terrains such as marsh, sand, mountain roads and beaches for taking water and the like; secondly, because the structure is compact and must be compact, when the engine needs to be periodically and/or repaired, the oil tank which shields the engine must be removed, otherwise, the engine cannot be monitored and protected due to the blockage of the oil tank. This results in an increased additional effort before the care on the one hand and a significant increase in the work intensity of the care staff on the other hand. In view of the foregoing, there is still a need for further improvement, and the technical solutions described below are made in this context.
