Description

Technical Field

[0001] This application relates to the technical field of drones, and in particular to a window-breaking device for a fire-fighting drone. Background Technology

[0002] As a new industrial technology, drone-based firefighting has been widely applied in various fields. In China, many fire departments have successfully used drones for fire scene reconnaissance and monitoring, and for dropping rescue supplies, with very significant results. During the Tianjin explosion rescue operation, various departments also used drones to conduct high-altitude reconnaissance of the accident site, providing some reference information for rescue decisions.

[0003] A search revealed Chinese Patent Publication No. CN213313008U, which discloses a window-breaking device for fire-fighting drones. The device includes a fixed housing, an impact device, and an auxiliary spring. The fixed housing is mounted on the fire-fighting drone. An opening is located at the front end of the tube, and the opening includes an adsorption part. The impact device is slidably mounted within the tube. The impact device includes an impact part connected to a driving part, which drives the impact part to slide. A locking device is provided between the driving part and the fixed housing to fix the impact device within the tube. The auxiliary spring is located between the fixed housing and the driving part, and when the locking device is unlocked, it drives the impact device to slide. By fixing the opening to the window, the reaction force when the driving part propels the impact device out of balance can be avoided, reducing the ejection force of the impact device. Simultaneously, the dual thrust improves the success rate of window breaking.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing technologies require the elasticity of a spring to push the impact part to break the window. Each use requires compressing the spring to store energy, which is inefficient and not suitable for high-frequency impacts. Moreover, the elasticity of the spring is prone to decrease after prolonged use, affecting the window-breaking effect. In order to overcome the shortcomings of the existing technologies, this application uses a drive motor and toothed blocks to drive the toothed column to reciprocate, thereby enabling the toothed column to drive the impact pin to impact at a high frequency, achieving the window-breaking effect.

A recoil chamber is fixedly connected to the outer surface of the drive chamber, and a motor chamber is fixedly connected to the upper surface of the drive chamber. A drive motor is fixedly installed inside the motor chamber, and a toothed block is fixedly connected to the output end of the drive motor.

[0014] 1.
