Embodiment Construction

[0033] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0034] Such as Figure 1-6 As shown, the water channel forming the V-shaped flow pattern in this embodiment includes an upstream rectangular water channel 1 , a gradual transition section water channel 2 , a downstream inverted trapezoidal water channel 3 , a water supply system 4 and a reservoir / return water system 5 . The inlet of the upstream rectangular waterway 1 is connected to the water supply system 4, the gradual change section waterway 2 is res...

Abstract

The invention discloses a water channel capable of forming a V-shaped flow state and used for fire fighting rescue and a flow state design method. The water channel comprises a water supply system, an upstream rectangular water channel, a transition section water channel, a downstream inverted trapezoidal water channel and a reservoir/backwater system which are sequentially communicated from top to bottom, wherein the bottom plate of the upstream rectangular water channel is a horizontal plane, the bottom plates of the transition section water channel and the downstream inverted trapezoidal water channel are slope surfaces, the side wall of the upstream rectangular water channel is a vertical surface, the side wall of the downstream inverted trapezoidal water channel is an inclined surface, and the side wall of the transition section water channel is provided with a flow guide element which gradually changes the side wall vertical surface of the upstream rectangular water channel into the side wall inclined surface of the downstream inverted trapezoidal water channel. The water channel utilizes the guiding effect of the guide element to guide water flow to the center of the water channel to change the direction, so that an inclined V-shaped flow state is formed.

Description

technical field [0001] The invention relates to a water channel for forming a V-shaped flow state in fire rescue and a flow state design method, belonging to the field of emergency rescue. Background technique [0002] Water area rescue is an extremely important content in emergency rescue missions. At present, the theoretical knowledge of water rescue personnel in my country is insufficient, and the training venues are scarce. The daily training is mostly based on basic physical fitness, fire fighting skills and equipment familiarity. The simulation training of water rescue is still limited to natural river waters, and there are few simulation training. Due to the complex topography of natural rivers and great danger, it is easy to cause casualties during the training process; when training in complex water environment, it is easy to lead to the deterioration of the psychological quality and judgment of the trainees, and there are emotions of anxiety, fear, and fear of diff...
