For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following is a further description with reference to the accompanying drawings and specific embodiments: Example 1

[0029] like Figure 1 , Figure 4 , Figure 5 As shown, an intelligent fire-fighting robot for construction sites includes a cylinder 1, a cylinder cover 2, a scissor lift 4, a battery pack 21 and a spray mechanism 5. The upper end of the cylinder 1 is set to be open, and the lower end is provided with multiple running wheels, wherein two running wheels are respectively set to be a driving wheel 11 and a guide wheel 12, and the driving wheel 11 and the guide wheel 12 are respectively connected to the motor. Therefore, with the cooperation of multiple running wheels, the cylinder 1 can be stably placed, and through the operation of the motor, the driving wheel 11 can be controlled to rotate to provide power for the movement of the cylinder 1. In addition, under the operation of the motor, the guide wheel 12 can be operated to change the direction of movement of the cylinder 1. Therefore, the cylinder 1 can be moved arbitrarily in the construction site to realize inspection, and provide support for timely discovery of fire and taking fire extinguishing measures. The cylinder cover 2 is sealed and detachably arranged above the cylinder 1. Specifically, the cylinder cover 2 and the cylinder 1 can be fastened by bolts, and a sealing ring is arranged at the intersection. A material pipe 23 is arranged on the cylinder cover 2, and the material pipe 23 provides a channel for the material to be output from the cylinder 1, and at the same time provides a channel for the high-pressure injection of carbon dioxide into the cylinder 1. The scissor lift 4 is arranged in the middle above the barrel cover 2, and the spray mechanism 5 is arranged at the upper end of the scissor lift 4. Therefore, the height of the spray mechanism 5 can be changed through the operation of the scissor lift 4 to provide support for the device to effectively extinguish fire sources at different positions. The battery pack 21 is arranged on the side above the barrel cover 2 to provide electrical energy for the operation of the entire device. The spray mechanism 5 includes an infrared thermometer 6, an industrial camera 7, a controller 57 and a spray head 55. The spray head 55 is connected to the material pipe 23 through a pipeline, and a solenoid valve can be provided at the connection between the spray head 55 and the pipeline, or a solenoid valve can be provided at the connection between the material pipe 23 and the pipeline to control whether the material pipe 23 is connected to the spray head 55. The controller 57 is connected to the battery pack 21, and controls the various components of the device to work in an orderly manner, and transmits information with the outside world, and can report the fire situation to the control center in time. The temperature of the construction site is measured in real time by the infrared thermometer 6, and the monitoring information is transmitted to the controller 57 (which can be set as a PLC). If it is found that the temperature fluctuates greatly, the controller 57 controls the device to move and explore the fire source. In the process of exploring the fire source, the industrial camera 7 takes real-time video to determine the location of the fire source, and then the controller 57 controls the solenoid valve to work, so that the spray head 55 is connected to the space formed by the cylinder 1 and the cylinder cover 2, and the high-pressure compressed carbon dioxide is transported to the spray head 55 along the pipeline and sprayed at the fire source, so as to realize intelligent fire extinguishing.

[0030] like Figure 7 , Figure 8As shown, in order to realize the adjustable setting of the injection head 55, the injection mechanism 5 also includes a supporting plate 51, a turntable 53 and a telescopic cylinder 54. The turntable 53 is arranged above the supporting plate 51, and the central axis fixedly arranged below the turntable 53 passes through the supporting plate 51 and is connected to the motor. The injection head 55 is arranged on a bracket above the turntable 53. A support shaft 56 is arranged at the upper end of the bracket. An arc plate 58 and an inclined plate are arranged on the support shaft 56. An elastic plate 59 is arranged at the upper end of the arc plate 58. The injection head 55 passes through the arc plate 58. The elastic plate 59 squeezes the injection head 55, that is, the injection head 55 is snap-fitted onto the arc plate 58. The lower end of the inclined plate is connected to the upper end of the telescopic cylinder 54, and the lower end of the telescopic cylinder 54 is connected to the turntable 53. When the direction of the spray head 55 needs to be adjusted, the motor and the telescopic cylinder 54 (such as an electric cylinder) work together to control the spray head 55 to rotate on the horizontal plane through the motor, and control the spray head 55 to rotate on the vertical plane through the telescopic cylinder 54, so as to achieve multi-directional adjustment of the spray head 55. Since the spray head 55 is set through the arc plate 58 and its position is limited by the elastic plate 59, it is convenient to remove the spray head 55 according to needs. For example, when the staff finds that the device is inconvenient to extinguish the fire due to foreign objects blocking it, the staff can remove the spray head 55 and manually hold it to aim at the fire source to achieve manual fire extinguishing, which changes the current situation of purely mechanical fire extinguishing of the existing fire-fighting robot and effectively improves the fire extinguishing effect.

One end of the threaded rod 42 is connected to the convex plate of the cylinder cover 2 through a bearing, and the other end is connected to the motor. Through the operation of the motor, the threaded rod 42 is controlled to rotate, thereby forcing the connecting rod 41 to move, controlling the deformation of the scissor lift 4, changing the position of the upper end of the scissor lift 4, and providing support for adjusting the position of the spray head 55. A buckle groove 52 is provided on the supporting plate 51, and one end is connected to the supporting plate 44 by bolts, and the other end is in sliding contact with another supporting plate 44. The buckle plate 43 is located in the buckle groove 52.
