Specifically, the fire extinguishing water bomb launcher for a plant protection unmanned aerial vehicle is configured as a split structure, which has components such as a hanging box 100, a mounting plate 200, a bottom cover 300, a hinge member 400, a first connecting portion 500, a second connecting portion 600, and a strap 700. When in use, the two bottom covers 300 are brought close to each other for fitting, and one end of the strap 700 away from the first connecting portion 500 is detachably connected to the second connecting portion 600. The mounting plate 200 is installed and connected to the plant protection machine, and the water bombs are placed in the hanging box 100. The plant protection machine drives the hanging box 100 above the fire point, and then the end of the strap 700 is separated from the second connecting portion 600. Under the gravity of the water bombs, the two bottom covers 300 move away from each other, causing the bottom of the hanging box 100 to open, and the water bombs automatically fall for fire extinguishing work. The water bomb launcher in this application not only has a simple design and low cost, but also is convenient to carry and launch water bombs, is easy to use, and can improve the work efficiency of fire extinguishing operations.

[0032] Please refer to Figures 1 to 5 , a fire extinguishing water bomb launcher for a plant protection unmanned aerial vehicle, including a hanging box 100. Mounting plates 200 for detachably connecting to the plant protection machine are fixed on any two opposite outer peripheral walls of the hanging box 100.

[0033] The hanging box 100 is in the shape of a rectangular box, with both the upper and lower ends of the hanging box 100 being open. A pair of symmetrically placed bottom covers 300 are provided at the bottom of the hanging box 100. Hinge members 400 are provided at the mutually remote ends of the two bottom covers 300, and the hinge members 400 are respectively installed on the peripheral walls of the corresponding ends of the hanging box 100. When the two bottom covers 300 are mutually fitted, the bottom of the hanging box 100 is hermetically sealed.

[0034] First connecting portion 500 and second connecting portion 600 are respectively and fixedly installed on the two peripheral walls of the hanging box 100 where the hinge members 400 are installed. A strap 700 is installed on the first connecting portion 500, and the other end of the strap 700 is detachably connected to the second connecting portion 600. And when the two bottom covers 300 are mutually fitted, the strap 700 is in a taut state and supports on the lower end surfaces of the two bottom covers 300.

[0035] The hanging box 100 is a rectangular box, and its structural design aims to provide stable support and accommodate water bombs. The capacity of the hanging box 100 is usually 20 - 100 liters. Commonly used materials for making the hanging box 100 are high-strength plastics or metal alloys, etc., which can ensure that the product has sufficient durability and stability during use.

[0036] The material of the bottom cover 300 is usually selected as wear-resistant and lightweight aluminum alloy, and its surface is subjected to technical treatments such as anti-corrosion coating or high-temperature spraying, etc., to increase the corrosion resistance and durability of the parts, thereby extending the product life.

[0037] The strap 700 serves to bind and support the bottom cover 300. The strap 700 can be made of nylon. Nylon is a lightweight, durable and material with good tensile properties. The strap 700 may need to be specially reinforced during manufacturing to resist external impacts or pressures.

[0038] The strap 700 is a closed-loop annular structure. Pull rings 701 are sleeved at both ends of the strap 700. The pull ring 701 at one end of the strap 700 is installed on the first connection part 500. Through the closed-loop strap 700, the strength of the strap 700 can be improved to avoid breakage when hoisting water bombs.

[0039] The first connection part 500 is a buckle. The buckle includes a base 501 fixed on the side wall of the hanging box 100. A buckle handle 502 is rotatably hinged at the lower end of the base 501. The pull ring 701 at one end of the strap 700 passes through the inside of the buckle handle 502 and is rotatably connected to it. When opening the buckle, the buckle handle 502 rotates around the hinge at the lower end of the base 501, and the buckle handle 502 drives the pull ring 701 at this end of the strap 700, causing the pull ring 701 to move downward. At this time, it is convenient to detachably install the other pull ring 701 with the second connection part 600. After the pull ring 701 of the strap 700 far from the first connection part 500 is installed with the second connection part 600, then close the buckle, so that the buckle handle 502 drives the connected pull ring 701 to move upward, tightening the strap 700.

[0040] The second connecting part 600 includes a housing 601 with an open lower end. The housing 601 is fixed to the side wall of the hanging box 100 away from the end of the first connecting part 500. Inside the hanging box 100, a pair of vertically downward fixed bars 602 are fixed. A horizontally placed circular through-hole is provided between the two fixed bars 602. A latch rod 603 is slidably connected between the two circular through-holes. A fixing ring 702 is fixedly installed on the pull ring 701 at the end of the strap 700 away from the first connecting part 500. The fixing ring 702 is sleeved on the latch rod 603. A driving member is provided inside the housing 601. The driving member is connected to one end of the latch rod 603 and is used to drive it to move along the circular through-hole. During installation, first, the driving member is used to drive the latch rod 603 to move, so that the latch rod 603 is pulled out from the fixed bar 602 away from the connecting member end. Then, the fixing ring 702 is placed between the two fixed bars 602. The driving member is used to drive the latch rod 603 to pass through the fixing ring 702 and insert it into the circular through-hole of the other fixed bar 602. When it is necessary to put in water bombs, the driving member is used to drive the latch rod 603 again, so that the fixing ring 702 can be detached, and the strap 700 can be separated from the second connecting part 600.

[0041] The driving member includes a rotating motor 604 fixed inside the housing 601. A horizontally placed rotating shaft is provided at the output end of the rotating motor 604. A first crank 605 is fixedly sleeved on the rotating shaft. The other end of the first crank 605 is rotatably hinged to a second crank 606. The end of the second crank 606 away from the first crank 605 is rotatably hinged to one end of the latch rod 603. By turning on the rotating motor 604, the output end of the rotating motor 604 drives the rotating shaft, the first crank 605, the second crank 606 and the latch rod 603 in sequence, which is convenient for automatically controlling the movement of the latch rod 603 in the circular through-hole and for automatically releasing the connection between the second connecting part 600 and the strap 700.

[0042] Preferably, a PLC controller for controlling the operation of the rotating motor 604 can be provided inside the housing 601. A signal receiver is installed on the housing 601, and a remote control for emitting signals is provided. After receiving the signal, the signal receiver transmits it to the PLC controller, and the PLC controller analyzes the signal and controls the operation of the rotating motor 604.

[0043] Preferably, the driving member can also be set as a telescopic cylinder. The output end of the telescopic cylinder is connected to the latch rod 603, and the latch rod 603 is driven to move by the telescopic cylinder.

[0044] The hinge member 400 is a hinge. The bottom cover 300 and the side wall of the hanging box 100 are rotatably hinged through the hinge. Preferably, the number of hinges provided on any bottom cover 300 is at least two, which can improve the connection stability between the bottom cover 300 and the hanging box 100, enable the bottom cover 300 to rotate around the hinge, and facilitate opening or closing the bottom cover 300.

[0045] A limiting ring 800 is installed on the bottom cover 300 corresponding to the end of the first connecting portion 500. The limiting ring 800 is located at one end of the bottom cover 300 away from the hinge member 400. One end of the strap 700 away from the first connecting portion 500 passes through the limiting ring 800. Through the arrangement of the limiting ring 800, the dislocation and sliding of the strap 700 after being tightened are avoided.

[0046] The mounting plate 200 is a right-angled strip plate placed obliquely downward. One side of the mounting plate 200 is fixed to the outer side wall of the hanging box 100, and the other side of the mounting plate 200 extends vertically towards the end away from the side wall of the hanging box 100. A card slot adapted to the side of the mounting plate 200 away from the side wall of the hanging box 100 is provided on the plant protection machine. And the mounting plate 200 is placed obliquely, which can cooperate with the gravity of the hanging box 100 to improve the stability of the installation and connection of the hanging box 100.
