Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle fire extinguishing devices, in particular to a barrel-type launching device for unmanned aerial vehicle-mounted fire extinguishing bombs. Background Art

[0002] With the rise of drones in recent years, scientific research teams in various countries are also developing drone equipment for high-rise building firefighting. At present, the high-rise building firefighting equipment that the fire department is most interested in is the firefighting drone. By carrying special fire-fighting bombs on the drone, fires in high-rise buildings can be quickly and accurately extinguished. However, there are certain safety hazards in the storage, transportation and use of existing drone fire-fighting bombs. The main manifestations are that accidental collisions during transportation may trigger the launch device of the fire-fighting bomb; during storage, changes in ambient temperature and humidity will affect the effectiveness of the fire-fighting bomb; during use, there is a lack of misoperation filtering mechanism, which is prone to misoperation accidents.

[0003] Generally, military airborne cartridge launchers usually use a slider to fit the airborne launcher, and use an electromechanical fuse to lock and unlock the missile. This type of launcher has extremely high design requirements. The presence of electrical and pyrotechnics has a significant impact on its working reliability. It also belongs to the pyrotechnic control field and has high costs, which limits its scope of civilian use. Summary of the invention

[0004] In view of the above technical problems, the purpose of the utility model is to provide a safe and reliable cylinder-type launching device for unmanned aerial vehicle-mounted fire extinguishing bombs, which can reliably lock the fire extinguishing bombs in the launching device when the fire extinguishing bombs are transported; during the storage of the fire extinguishing bombs, the launching tube and its front and rear fragile membranes ensure that the fire extinguishing bombs are stored in a dry and enclosed space, ensuring the long-term storage performance of the fire extinguishing bombs; before the fire extinguishing bombs are used, the operator can manually and conveniently unlock them on the ground to make the fire extinguishing bombs ready for launching; when the fire extinguishing bombs are launched, the launching device gives the fire extinguishing bombs an initial direction.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme.

[0006] The utility model discloses a cylinder-type launching device for fire-extinguishing bombs carried by unmanned aerial vehicles, comprising a launching tube and a bomb body installed in the inner cavity of the launching tube, a locking mechanism is fixedly installed on the outer wall of the launching tube, the locking mechanism comprises a through hole arranged on the outer wall of the launching tube, a locking pin connected to the outer wall of the launching tube by threads, a locking pin hole is arranged on the bomb body, the locking pin hole and the through hole are both located on the axis of the locking pin, and the outer end of the locking pin is fixedly connected to the rotating handle.

[0007] Through this solution, during transportation and storage, the locking mechanism fixes the fire extinguishing bomb body axially in the launching device, and the launching tube constrains the bomb body circumferentially, thereby improving the safety during transportation and storage.

[0008] Preferably, a locking pin seat is fixedly installed on the outer wall of the launching tube at a position corresponding to the through hole, and an internal threaded hole is provided on the locking pin seat. The internal threaded hole is coaxially arranged with the through hole, and the locking pin is installed in the internal threaded hole.

[0009] Through this solution, the locking pin and the locking pin seat are firmly connected, which is beneficial to improving the reliability of the locking pin when in use.

[0010] Preferably, fragile membranes are installed at both ends of the launching tube.

[0011] Through this solution, the front and rear fragile films ensure that the storage environment in the cylinder remains dry during the storage period, avoiding the failure of the fire extinguishing bomb caused by changes in environmental humidity.

[0012] Preferably, an electronic connector adapter and a UAV mechanical interface are installed on the launching tube.

[0013] Through this solution, it can be easily connected to the drone carrier.

[0014] Preferably, the launching tube is made of a composite material wrapped with glass fibers; and the locking pin seat is fixed to the launching tube by binding with glass fibers.

[0015] Through this solution, the launching tube is light in weight and high in strength, and the locking pin seat is firmly connected to the launching tube and is not easy to fall off.

[0016] Preferably, a linkage protection box is arranged between the electronic connector adapter and the locking mechanism, and the linkage protection box includes a box cover covering the electronic connector adapter and a linkage plate fixedly connected to the box cover, the box cover is clamped on the electronic connector adapter, and the linkage plate is clamped on the locking pin.

[0017] Through this solution, the linkage protection box can be removed to connect the fire extinguishing bomb to the external transmitting power supply only after the locking pin is released, so as to prevent the fire extinguishing bomb from being launched without being unlocked, thereby ensuring the safety of the fire extinguishing bomb and the UAV.

[0018] The technical effects of the utility model are embodied in the following aspects:

[0019] (I) The utility model is a launch device designed for fire-extinguishing bombs carried by unmanned aerial vehicles. The launch tube of the main structure is formed by winding glass fiber, which has the distinctive characteristics of light weight and high strength, and can meet the stringent requirements of unmanned aerial vehicles on their load weight.

[0020] (II) The utility model makes a design guarantee for the safety of launch. Before executing the fire-fighting task, the lock is manually unlocked. Only after the lock is unlocked in place can the linkage protection box be removed, and then the fire-extinguishing bomb can be connected to the external launch power supply to ensure the safety of the fire-extinguishing bomb. That is, when the linkage protection box is not removed, the electrical interface between the launch device and the UAV is in a state of being protected by the linkage protection box; and when the fire-extinguishing bomb is in the storage and transportation state, the linkage protection box docking plug-in is used for sand and dust protection.

[0021] (III) The utility model fully considers the reliability of the performance of the fire extinguishing bomb during transportation and storage. During storage, the launch tube and front and rear fragile membranes of the launch device ensure that the fire extinguishing bomb is stored in a dry environment; during transportation, the locking mechanism ensures that the fire extinguishing bomb is reliably locked axially in the launch tube, and the inner wall of the launch tube constrains the fire extinguishing bomb circumferentially.

[0022] (IV) The present invention fully considers ergonomics. The design of the handle and the locking mechanism fully considers the feasibility of operation by firefighters wearing cotton gloves in winter; the front and rear fragile membrane screws are connected to the front and rear end surfaces of the launch tube to fully consider the convenience of fire extinguishing bomb maintenance and life extension; the connector, linkage protection box, and locking mechanism are all designed on the same side of the handle, so as to prevent the connector, linkage protection box, and locking mechanism from unnecessary bumps when the firefighters use the handle to carry the fire extinguishing bomb.

[0027] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the utility model. These all fall within the scope of protection of the utility model. The utility model is further described in detail in conjunction with the accompanying drawings and preferred embodiments as follows:

[0028] like Figure 1As shown, the utility model of a barrel-type launch device for fire-extinguishing bombs carried by unmanned aerial vehicles comprises a launch barrel 101 and a bomb body 302 installed in the inner cavity of the launch barrel 101, and a locking mechanism 103 is fixedly installed on the outer wall of the launch barrel 101. The launch barrel 101 is a cylindrical structure made of glass fiber wrapped with composite materials, with a thickness of about 2mm and a mass of only about 2kg. The characteristics of light weight and high strength can meet the stringent requirements of unmanned aerial vehicles for carrying loads; fragile membranes 106 are installed at both ends of the launch barrel 101. There is one fragile membrane 106 on the front and rear end faces of the launch barrel 101, and the fragile membrane 106 covers the end face of the launch barrel 101 and is fixedly connected along the periphery of the end face of the launch barrel 101 with screws. The front and rear fragile membranes and the launching tube ensure that the fire extinguishing bomb is stored in a dry environment in the tube during the storage period. When launched, the fire extinguishing bomb relies on the kinetic energy in the shooting direction provided by the engine to open the front fragile membrane, and relies on the engine pressure to open the rear fragile membrane. The fire extinguishing bomb body is launched toward the target along the axis of the launching tube. The fragments of the fragile membrane will not have any adverse effect on the fire extinguishing bomb itself.

[0029] like Figure 2 , Figure 3 As shown, the locking mechanism 103 includes a through hole 209 provided on the outer wall of the launch tube 101, a locking pin 202 connected to the outer wall of the launch tube 101 by threads, a locking pin hole 312 provided on the projectile body 302, the locking pin hole 312 and the through hole 209 are both located on the axis of the locking pin 202, and the outer end of the locking pin 202 is fixedly connected to the rotating handle 201. A locking pin seat 113 is fixedly installed on the outer wall of the launch tube 101 at a position corresponding to the through hole 209, and the locking pin seat 113 is tied and fixed to the launch tube 101 by glass fiber 301. An internal threaded hole is provided on the locking pin seat 113, and the internal threaded hole is coaxially arranged with the through hole 209, and the locking pin 202 is installed in the internal threaded hole. When the fire extinguishing bomb is stored and transported, the locking mechanism 103 reliably locks the fire extinguishing bomb in the launch tube 101 to prevent the fire extinguishing bomb from moving freely in the launch tube 101 and affecting its performance and product integrity.

[0030] The locking mechanism 103 is fixed on the outer wall of the launch tube 101. By rotating the locking pin 202 through the rotary handle 201, the locking pin 202 can be moved axially, and the locking pin 202 can be withdrawn from the locking pin hole 312 provided on the projectile 302 and retracted into the locking pin seat 113, thereby unlocking the projectile 302 in the launch tube 101.

[0031] In addition, in order to facilitate the use of drones, the launch tube 101 is equipped with an electronic connector adapter 105 and a drone mechanical interface 108. The electronic connector adapter 105 is provided with an inner electrical interface and an outer electrical interface for electrical connection. The inner electrical interface is located in the inner cavity of the launch tube 101 and connected to the projectile 302. The outer electrical interface is located outside the launch tube 101 and is connected to the drone electrical interface when in use, so as to facilitate the use of the drone to control the launch of the projectile 302. The drone mechanical interface 108 realizes the mechanical connection between the launch tube 101 and the drone.

[0032] A linkage protection box 104 is arranged between the electronic connector adapter 105 and the locking mechanism 103. The linkage protection box 104 includes a box cover 114 covering the electronic connector adapter 105 and a linkage plate 124 fixedly connected to the box cover 114. The box cover 114 is clamped on the electronic connector adapter 105, and the linkage plate 124 is clamped on the locking pin 202.

[0033] like Figure 3 As shown, when the locking mechanism 103 is in the locked state, the linkage plate 124 of the linkage protection box 104 is pressed under the rotary handle 201, and the linkage protection box 104 cannot be removed from the electronic connector adapter 105, and thus cannot be connected to the electrical interface of the drone. Figure 4 As shown, when the locking mechanism 103 is in the unlocked state, the handle 201 pressing the linkage plate 124 is released, and the linkage protection box 104 can be removed from the electronic connector adapter 105, thereby exposing the external electrical interface of the electronic connector adapter 105, and connecting the external electrical interface to the electrical interface of the drone, thereby forming the launch condition for the fire extinguishing bomb body 302 to be unlocked and launched in the launch tube 101.
