Description

Technical Field

[0001] This utility model relates to the field of tear gas spray technology, specifically a tear gas spray modification kit for use on drones. Background Technology

[0002] Tear gas is a chemical substance that emits tear gas, causing irritation and tearing. It can be launched in the form of a jet or a grenade and is widely used to disperse demonstrators in riot situations. It can also be used as a weapon. With the advancement of technology, drones can safely and reliably deliver the munitions. Currently, drones carrying tear gas canisters drop the munitions directly onto the ground. This allows demonstrators to pick up the munitions and throw them at police locations or unoccupied areas. In addition, current drone-borne tear gas canisters can only disperse the tear gas in one location, resulting in a slow spread and a short duration of use.

[0003] To address the shortcomings of traditional training sprayers, such as high cost, non-reusability, and short usage time, this solution proposes a tear gas sprayer modification kit for drone mounting. Utility Model Content

[0004] The purpose of this invention is to provide a tear gas spray modification kit for use on drones, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modification kit for a tear gas sprayer mounted on a drone, comprising a drone, a mounting bracket fixedly mounted on the top of the drone and a mounting box fixedly mounted on the bottom of the drone, a storage box threaded onto the mounting bracket, a feeding tube fixedly mounted on the top of the storage box, a sealing cap threaded onto the feeding tube, a mounting box rotatably mounted inside the mounting box, a tear gas sprayer fixedly mounted on the mounting box, and a through hole provided on the mounting box, a common connecting hose fixedly mounted between the tear gas sprayer and the storage box, and a mounting rod fixedly mounted on the top of the tear gas sprayer, with a rotatable mounting attachment on the mounting rod. A rotating shaft has a swing arm and a connecting rod fixedly sleeved at both ends. A movable rod is movably installed in the through hole. One end of the movable rod is rotatably connected to the connecting rod, and the other end of the movable rod is rotatably connected to a linkage rod. A servo motor is fixedly installed in the fixed box. A turntable is fixedly sleeved on the output shaft of the servo motor. The top of the turntable is rotatably connected to the linkage rod. A push switch is provided on the top of the tear gas sprayer. A press block is fixedly installed on the swing arm. Fixed rods are fixedly installed at the four corners of the top of the drone. A propeller is rotatably installed on any fixed rod, and a light is fixedly installed at the bottom of any fixed rod. A photosensitive module is provided on the servo motor.

[0006] Preferably, the sealing cap has anti-slip texture.

[0007] By adopting the above technical solution, users can easily increase friction when adding or removing the sealing cover, preventing slippage and ensuring the safety and convenience of operation.

[0008] Preferably, a micro motor is fixedly installed inside the mounting box, a micro lead screw is fixedly sleeved on the output shaft of the micro motor, a lead screw guide sleeve is threaded onto the micro lead screw, a support connecting rod is rotatably installed between the lead screw guide sleeve and the fixed box, a slide rail is fixedly installed inside the mounting box, a slider is slidably installed on the slide rail, and the slider is fixedly connected to the lead screw guide sleeve.

[0009] By adopting the above technical solution, the horizontal movement of the lead screw guide sleeve can be achieved through the drive of the micro motor, and then the rotation of the fixed box and the tear gas sprayer can be driven by the support connecting rod, so as to achieve flexible adjustment of the spray direction. The slide rail and slider facilitate the stable horizontal movement of the lead screw guide sleeve.

[0010] Preferably, a wireless control module connected to the wires of the micro motor is fixedly installed inside the mounting box.

[0011] By adopting the above technical solution, the start and stop of the micro motor can be remotely controlled wirelessly through the wireless control module, thereby remotely adjusting the spray direction of the tear gas sprayer and improving the flexibility and safety of operation.

[0012] Preferably, multiple heat dissipation holes are provided on both sides of the fixing box.

[0013] By adopting the above technical solution, the heat generated by the servo motor inside the fixed box during operation can be effectively dissipated, preventing equipment failure due to overheating and improving the stability and service life of the servo motor.

[0014] Preferably, a return spring is sleeved on the movable rod, with one end of the return spring fixed to the movable rod and the other end fixed to the inner wall of the through hole.

[0015] By adopting the above technical solution, after the servo motor drives the turntable to rotate, the elastic force of the return spring can restore the moving rod, connecting rod, swing rod and other components to their initial positions, preparing them for the next operation and ensuring the stability and reliability of the mechanical transmission.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0019] III. High-efficiency diffusion and coverage: The micro-motor drives the spray direction adjustment mechanism, which, combined with the flexible movement of the drone, enables multi-angle and multi-position spraying, accelerating the diffusion speed and coverage of the tear gas.

[0020] IV. Extended service life: The storage tank is continuously supplied with material through a connecting hose, and a single filling can meet the needs of long-term spraying, far exceeding the time limit of traditional disposable ammunition.

[0021] V. Reliable Structure and Easy Maintenance: Lever linkage and photosensitive control simplify mechanical transmission, and the overall modular design facilitates quick maintenance and improves equipment durability. Attached Figure Description
