Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically, it relates to a tethered, power-supplying dry powder firefighting UAV. Background Technology

[0002] As a new industrial technology, drone firefighting has been widely used in various fields. Many fire departments have successfully used firefighting drones to conduct fire scene reconnaissance and monitoring, and drop rescue supplies, with very obvious results. The entire fuselage is made of new carbon fiber materials, providing a safe and fireproof power system.

[0003] Firefighting drones are characterized by precise fire location, clear imaging, real-time fire risk data monitoring, instant monitoring, night flight capability, wireless digital transmission, and avoidance of overhead power lines. These drones can be quickly relocated and can conduct fire reconnaissance and rapid fire suppression over large areas of urban high-rise buildings and forests. However, these firefighting drones are generally battery-powered, and the battery life is limited. When continuous firefighting is required, this will seriously affect the progress of firefighting, reduce the efficiency and effectiveness of fire suppression. Furthermore, since the charging and storage time of rechargeable batteries is limited, batteries need to be charged and discharged periodically. If the battery supply is insufficient during a fire, it will delay the opportunity to fight the fire.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A tethered power supply dry powder firefighting drone includes a drone body. A tethered power supply onboard unit is fixedly installed at the bottom of the drone body. A tethered cable is connected to the bottom of the tethered power supply onboard unit and is electrically connected to the tethered cable. A landing gear is fixedly installed at the bottom of the drone body. Symmetrically arranged fixing plates are fixedly connected to the landing gear. A common storage reel is fixedly connected to the outer wall of opposite sides of the two fixing plates. A positioning hole is opened at the end of the storage reel. The diameter of the positioning hole is larger than the diameter of the tethered cable.

[0007] In a preferred embodiment of this utility model, the landing gear is fixedly connected to symmetrically arranged mounting plates at its bottom, and the two mounting plates are fixedly connected to the same support base on opposite sides of their bottoms.

[0008] In a preferred embodiment of this utility model, the top of the support base is provided with an installation groove, the inner wall of the installation groove is slidably provided with an installation seat, the top outer wall of the installation seat is fixedly connected with a tank seat, and the inner wall of the tank seat is fixedly provided with a dry powder tank.

[0009] In a preferred embodiment of this utility model, a symmetrically arranged positioning plate is fixedly connected to one side of the outer wall of the mounting base, and both positioning plates are connected to the support base by bolts.

[0010] In a preferred embodiment of this utility model, a spray bar is connected to the outlet of the dry powder tank, and a solenoid valve is provided at the outlet of the dry powder tank. A nozzle is fixedly connected to the end of the spray bar.

[0011] In a preferred embodiment of the present invention, a sturdy support is fixedly connected to the outer wall of the spray bar, and a sturdy support rod is fixedly connected to one side of the outer wall of each of the two fixed plates. The two sturdy support rods are symmetrical to each other, and one end of each of the two sturdy support rods is fixedly connected to the outer walls of the two sides of the sturdy support.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention, through the onboard terminal of the tethered power supply and the tethered cable, allows the AC power (V) generated by the generator on the ground to be stepped up by a power conversion device and converted into DC power (V). This DC power is then delivered to the onboard terminal of the tethered power supply via the tethered cable, where it is stepped down to a safe voltage (V) to power the electronic equipment and flight propulsion system on the UAV. When the tethered cable is not needed, it can be wound up and stored on a storage reel. After storage, the end of the tethered cable is passed through the positioning hole and secured to the end of the storage reel.

[0014] This invention, through the design of a support base, mounting groove, mounting seat, canister base, and positioning plate, allows the dry powder canister to be securely installed at the bottom of the drone body. When the dry powder canister needs to be replaced, the spray bar is removed from the discharge port of the dry powder canister. After disassembly, the positioning plate is removed from the support base. After removal, the mounting seat is pulled and moved within the mounting groove until it moves to the outside of the support base, at which point the dry powder canister can be removed. This facilitates replacement of the dry powder canister when it runs out. When firefighting is required, the drone body is controlled to fly to the fire location, and the solenoid valve at the dry powder canister discharge port is opened, allowing the dry powder to be sprayed towards the fire location through the spray bar and nozzle, thus achieving firefighting.
