Problems solved by technology

However, the current wind-powered fire extinguishing robot must be equipped with a large-sized, high-thrust fire-extinguishing fan to ensure a large fire-extinguishing wind, which requires a larger and heavier chassis.

Embodiment 1

[0033] Such as figure 1 As shown, a wind fire extinguishing device for a fire extinguishing robot in a narrow space described in this embodiment includes a group of two motors, an electronic speed controller, a mounting base, a mounting arm and a steering gear for driving the mounting arm, and the two motors are respectively Located on both sides of the mounting base, the propellers are connected to their respective motors to drive, the mounting arm is connected to the mounting base, and the steering gear that drives the mounting arm. A group of two motors are symmetrically installed on the mounting base, each motor drives a propeller to generate fire-extinguishing wind, the two motors and the propellers driven by them turn in opposite directions, and the direction of the fire-extinguishing wind blows to both sides. The mounting arm is driven by the servo to change the wind direction of the two motors, thereby realizing fire extinguishing.

[0034]Further, if the two motors a...

Embodiment 2

[0041] The only difference between this embodiment and Embodiment 1 is that the axes of the two motors are installed in a misaligned position, and the specific parameters are as follows: (1) The position of the two screw drive assemblies (motor, propeller) relative to the rotatable end of the mounting arm The vector sum of the generated torque is less than 5% of the maximum output torque of the steering gear; (2) The selection of parameters such as the rotational speed of the two motors meets the parameter selection rules mentioned above. Generally speaking, the distance between the axes of the two motors is 0.2-0.45 times the diameter of the two propellers.

Embodiment 3

[0043] The difference between this embodiment and Embodiment 1 is that a rectifier is installed between the two motors, and the rectifier is formed by rotating a parabola around the motor axis. A two-dimensional coordinate system is established with the vertices of the parabola. The Y axis of the two-dimensional coordinate system is parallel to the axis of the power output shaft of the motor, and the mounting arm points to the motor. The parabolic equation can be expressed by y 2 =-2px, where the value of p is 0.25~0.3d, and d is the distance from the blade tip track circle to the mounting seat when the propeller rotates.

Abstract

The invention discloses a wind fire-extinguishing device for a fire-fighting robot used in a narrow and small space. The wind fire-extinguishing device comprises a steering engine, a rotary installation arm and spiral driving assemblies. The power output end of the steering engine is connected with the installation arm. One end of the installation arm is a rotatable end, and at least one set of spiral driving assemblies is mounted at the other end of the installation arm. Each set of spiral driving assemblies includes two spiral driving assemblies which are separately arranged at the two endsof the working end of the installation arm. Each spiral driving assembly comprises an installation base, a motor and a propeller. The two propellers in each set of the spiral driving assemblies are driven by a power output shaft of the corresponding motor to steer and to rotate reversely. According to the wind fire-extinguishing device for the fire-fighting robot used in a narrow and small space,the purpose of minimizing the size and weight of a chassis is realized while strong wind is ensured, the chassis is made smaller and lighter, and the wind fire-fighting robot can shuttle in jungles, buildings and other narrow and small spaces to fight fires.

Description

technical field [0001] The invention relates to the technical field of intelligent equipment, in particular to a wind fire extinguishing device for a fire extinguishing robot. Background technique [0002] With the development of science and technology and the improvement of actual demand, in the future, fire extinguishing in small spaces will rely more and more on fire extinguishing robots. Traditional fire-fighting robots are bulky, complex, and huge in size, and cannot perform fire-fighting tasks in complex and narrow spaces such as jungles and buildings. Therefore, it is extremely urgent to develop a fire-fighting robot with simple structure, light weight, small size and easy control. [0003] At present, there are mainly the following types of fire extinguishing robots, namely water storage type, foam storage type, carbon dioxide storage type, and wind power type. Water storage type, foam storage type, and carbon dioxide storage type are the most commonly used fire ex...
