Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) firefighting, in particular to a UAV dual-fire glass-breaking device and a glass-breaking bomb. Background Art

[0002] With the rapid development of the construction industry, more and more high-rise buildings are rising from the ground. In the event of fire or other special circumstances, these high-rise buildings generally rely on breaking windows to create access routes. Traditional high-altitude window breaking methods, generally using ladders and manual labor, are not only time-consuming but also pose safety risks to the operators involved. This makes it no longer suitable for existing high-rise window breaking rescue operations.

[0003] Currently, breaking windows in high-rise buildings is typically accomplished by using firefighting drones equipped with window-breaking grenades, which are then fired pneumatically or with gunpowder to strike the windows. The impact location is typically confirmed by the drone's onboard camera. During this confirmation and firing process, there can be deviations in the impact position, resulting in a single shot failing to effectively shatter the glass. Most current drones can only fire a single window-breaking grenade, lacking error tolerance. After firing, if the window is not broken, the drone must be controlled to return and reload. This results in a lack of error tolerance and low window-breaking efficiency in the current drone-mounted window-breaking grenade launcher.

[0004] In the utility model with application number: CN202321396981.7 and publication number: CN219948545U, a drone glass-breaking ball launching mechanism for a drone fire truck is disclosed, which includes a protective shell, a pneumatic device is arranged on the right side of the interior of the protective shell, and a plurality of first punching tubes and a plurality of second punching tubes are arranged in a circular array on the left and right sides of the pneumatic device.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] like Figure 1 As shown, in order to solve the above problems, this embodiment discloses a UAV dual-engine glass breaking device, comprising:

[0035] A fixing assembly 10, which is used to connect to the UAV tripod;

[0036] A pair of glass-breaking bullet launching assemblies 20 are cooperatively arranged at the lower end of the fixing assembly 10 and are respectively fixedly connected to both sides of the lower end of the fixing assembly 10. The pair of glass-breaking bullet launching assemblies 20 can respectively carry and launch one glass-breaking bullet.

[0037] The present invention is provided with a fixing assembly 10 and a pair of glass-breaking bullet launching assemblies 20. When in use, the pair of glass-breaking bullet launching assemblies 20 can be fixed to the tripod of the drone via the fixing assembly 10. Then, each of the pair of glass-breaking bullet launching assemblies 20 carries a glass-breaking bullet. When glass breaking is required, one of the glass-breaking bullet launching assemblies 20 is first used to launch a glass-breaking bullet to break the glass. If the glass is not broken, the other glass-breaking bullet launching assembly 20 can directly launch another glass-breaking bullet to break the glass. Compared with traditional glass-breaking devices carried by drones, the present invention can carry two glass-breaking bullets at the same time, has better fault tolerance and higher window-breaking efficiency when breaking glass, and solves the problem of the current window-breaking bullet launching mechanism carried by drones, which can only carry one window-breaking bullet when in use, resulting in a lack of fault tolerance and low window-breaking efficiency.

[0038] When in use, the utility model can carry two glass-breaking bombs at the same time and can be fired separately. When a single glass-breaking bomb fails to break the glass, the remaining glass-breaking bomb can be used to break the glass again. There is no need to return directly to refill the glass-breaking bomb, which saves the round-trip time of the drone and improves the efficiency of glass breaking. It can save a lot of time in case of fire and facilitate fire fighting and rescue.

[0039] like Figures 2 to 5 As shown, in order to facilitate the launch of glass-breaking bullets, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the glass-breaking bullet launching assembly 20 includes a shell 200, an air drive component 201 and a launch tube 202. The shell 200 includes a protective shell 203 and a protective cover 204. The protective shell 203 is provided with a mounting cavity 205. The mounting cavity 205 passes through the rear end of the protective shell 203. The protective cover 204 is provided at the rear end of the protective shell 203 and is connected to the protective shell 203. Removable connection, the air drive component 201 is arranged in the installation cavity 205 and is detachably connected to the protective shell 203. The front end of the protective shell 203 is provided with a through-hole 206 connected to the installation cavity 205. The front end of the air drive component 201 can extend from the through-hole 206 to the outside of the installation cavity 205. The launch tube 202 is detachably connected to the front end of the air drive component 201. The front end of the protective cover 204 can be inserted into the installation cavity 205 and contact with the rear end of the air drive component 201 to fix the air drive component 201.

[0040] When in use, the glass-breaking bomb can be driven by the gas-driven component 201, and then the glass-breaking bomb is launched along the launching tube 202, thereby facilitating the launch of the glass-breaking bomb.

[0041] like Figure 5 As shown, in order to facilitate the installation or replacement of the air drive component 201, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a limiting snap ring 207 is provided at the front end of the protective cover 204, and a limiting groove 208 is provided in the installation cavity 205 to cooperate with the limiting snap ring 207. When the front end of the protective cover 204 is inserted into the installation cavity 205 and the end portion contacts the rear end of the air drive component 201, the limiting snap ring 207 is clamped in the limiting groove 208.

[0042] The protective cover 204 is provided with a threading opening 209 penetrating the protective cover 204 .

[0043] The protective cover 204 and the protective shell 203 are matched by the limiting snap ring 207 and the limiting slot 208. During installation, the protective cover 204 can be pulled out to complete the separation of the protective cover 204 and the protective shell 203, and then the air drive component 201 can be installed into the installation cavity 205 or removed from the installation cavity 205. When installing the air drive component 201, it is only necessary to buckle the protective cover 204 into the protective shell 203, so that the limiting snap ring 207 is engaged in the limiting slot 208, and at the same time, the end of the front end of the protective cover 204 is in contact with the rear end of the air drive component 201 to complete the installation of the air drive component 201.

[0044] like Figures 3 to 5 As shown, in order to facilitate the gas-driven component 201 to drive the glass-breaking bomb, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the gas-driven component 201 includes a housing 210, a connector 211 and a blocking diaphragm 212. A housing cavity 213 is provided in the housing 210. The housing cavity 213 passes through the front end of the housing 210. The housing cavity 213 is filled with a gas generating agent. A trigger circuit 214 for triggering the gas generating agent to generate gas is provided at the rear end of the housing 210. One end of the trigger circuit 214 passes through the rear end of the housing 210 and extends to In the accommodating cavity 213, the other end of the trigger circuit 214 can extend from the threading port 209 to the outside of the protective cover 204, and the front end of the connector 211 can extend from the through port 206 to the outside of the installation cavity 205. The rear end of the connector 211 can be inserted into the accommodating cavity 213 and threadedly connected to the accommodating shell 210. A gas flow channel 215 passing through the connector 211 is provided in the connector 211, and a blocking diaphragm 212 is provided in the gas flow channel 215 for isolating the gas flow channel 215. One end of the launch tube 202 can be inserted into the gas flow channel 215 and is detachably connected to the front end of the connector 211.

[0045] The glass-breaking bullet can be loaded into the launch tube 202 and slidably connected to the launch tube 202 .

[0046] Among them, the gas flow channel 215 includes a first flow channel 216 and a second flow channel 217. The first flow channel 216 is arranged at the front end of the connecting head 211, and the second flow channel 217 is arranged at the rear end of the connecting head 211. A partition plate 218 is provided between the first flow channel 216 and the second flow channel 217. The partition plate 218 is provided with an air vent 219 for connecting the first flow channel 216 and the second flow channel 217. The diameter of the air vent 219 is smaller than the diameter of the first flow channel 216 and the second flow channel 217. The blocking diaphragm 212 is arranged in the second flow channel 217 and is detachably connected to the partition plate 218 by bolts. One end of the launch tube 202 can be inserted into the first flow channel 216 and is detachably connected to the inner wall of the first flow channel 216 by threads.

[0047] The blocking membrane 212 is made of a sealing aluminum foil and is arranged in conjunction with the vent hole 219 .

[0048] During use, the gas generating agent can be triggered through the trigger circuit 214, and then the gas generating agent generates gas to increase the gas and pressure of the accommodating cavity 213, so that the gas passes through the second flow channel 217, and then destroys the blocking diaphragm 212, and then enters the first flow channel 216 from the vent 219, and then enters the launch tube 202 from the first flow channel 216, thereby pushing the glass-breaking bullet in the launch tube 202 to be launched to break the glass.

[0049] Among them, the diameter of the vent hole 219 is smaller than the diameter of the first flow channel 216 and the second flow channel 217, so that the first flow channel 216, the vent hole 219 and the second flow channel 217 can form a venturi tube, thereby increasing the flow rate of the gas entering the first flow channel 216 from the second flow channel 217, thereby allowing the glass-breaking bullet to be launched faster.

[0050] When the rear end of the connector 211 is screwed into the accommodating cavity 213 , the sealing between the connector 211 and the accommodating shell 210 can be improved by adding sealant.

[0051] like Figure 5 As shown, in order to facilitate the installation of the air-driven component 201, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a clamping ring body 220 is fixedly provided on the outer side of the rear end of the connecting head 211, and a limiting portion 221 is provided at the front end of the protective shell 203 to cooperate with the clamping ring body 220, and the clamping ring body 220 can contact and limit the limiting portion 221.

[0052] The arrangement of the snap ring 220 and the limit portion 221 can prevent the air drive component 201 from being separated from the front end of the protective shell 203 during installation.

[0053] A plurality of grooves are provided on the outer side of the clamping ring body 220 . The provision of the grooves can facilitate the rotation of the connector 211 , thereby facilitating the threaded connection between the connector 211 and the accommodating shell 210 .

[0054] like Figure 6As shown, in order to facilitate the mounting of a pair of glass-breaking bullet launching assemblies 20 on the drone tripod, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the fixing assembly 10 includes a fixing clamp seat 100 and a fixing clamp block 101. The fixing clamp block 101 is arranged on the top of the fixing clamp seat 100 and is detachably connected to the fixing clamp seat 100 by a locking bolt. The fixing clamp seat 100 and the fixing clamp block 101 are respectively provided with an arc-shaped clamping groove 102 for clamping the drone tripod. When the fixing clamp seat 100 and the fixing clamp block 101 are connected, a clamping inner hole for clamping the drone tripod can be formed between the two arc-shaped clamping grooves 102. Arc-shaped matching grooves 103 are provided on both sides of the lower end of the fixing clamp seat 100 and are matched with the protective shell 203. The protective shell 203 in the pair of glass-breaking bullet launching assemblies 20 is fixedly connected to the arc-shaped matching grooves 103.

[0055] When in use, the pair of glass-breaking bullet launching assemblies 20 can be quickly mounted on the tripod of the UAV through the cooperation of the fixing clamp seat 100 and the fixing clamp block 101, which facilitates the mounting of the pair of glass-breaking bullet launching assemblies 20.

[0056] like Figure 7 As shown, a glass-breaking bomb is used in the above-mentioned dual-fired glass-breaking device for unmanned aerial vehicles, including a glass-breaking bomb body 30 and a glass-breaking warhead 31. The front end of the glass-breaking warhead 31 is a sharp end and the rear end is a cylindrical end. The cylindrical end of the glass-breaking warhead 31 is arranged at the front end of the glass-breaking bomb body 30 and is fixedly connected to the glass-breaking bomb body 30. An annular groove 300 is provided on the glass-breaking bomb body 30, and a sealing ring 301 is provided in the annular groove 300. The sealing ring 301 is fixedly connected to the annular groove 300. When the glass-breaking bomb is loaded into the launch tube 202, the sealing ring 301 forms a seal with the inner wall of the launch tube 202.

[0057] During use, the provision of the sealing ring 301 can create a certain friction between the glass-breaking bullet and the launch tube 202 , thereby preventing the glass-breaking bullet from easily escaping from the launch tube 202 .

[0058] The glass-breaking bullet 31 is made of tungsten alloy and has a sharp end. When fired, the sharp end is used to break the glass, which can achieve better glass-breaking efficiency.

[0059] like Figure 8 As shown, in order to facilitate the installation of the glass-breaking bullet, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that it also includes a pusher 40, which includes a pusher head 400, a pusher rod 401 and a handle 402 fixedly connected in sequence. The pusher head 400 is provided with a matching groove 403 that is matched with the sharp end of the glass-breaking bullet 31. One end of the pusher head 400 of the pusher 400 can be inserted into the launch tube 202 and slidably matched with the launch tube 202.

[0060] The arrangement of the ejector 40 can facilitate the loading of the glass-breaking bullet into the launch tube 202 .

[0061] Working principle of this utility model:

[0062] The present invention comprises a fixing assembly 10 and a pair of glass-breaking bullet launching assemblies 20. During use, the fixing assembly 10 can be used to fix the pair of glass-breaking bullet launching assemblies 20 to the tripod of a drone. Each of the pair of glass-breaking bullet launching assemblies 20 then carries a glass-breaking bullet. When glass breaking is required, one of the glass-breaking bullet launching assemblies 20 first launches a glass-breaking bullet to break the glass. If the glass is not broken, the other glass-breaking bullet launching assembly 20 can directly launch another glass-breaking bullet to break the glass. Compared to traditional glass-breaking devices carried by drones, the present invention can carry two glass-breaking bullets simultaneously, providing better fault tolerance and higher window-breaking efficiency.

[0063] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
