Description

Technical Field

[0001] This invention relates to the field of camouflage smoke emission technology, and in particular to a gas-jet smoke camouflage device. Background Technology

[0002] The purpose of camouflage is to ensure the concealment and security of military targets, improve battlefield survivability, eliminate various forms of exposure, and prevent them from being detected. All targets should be concealed when conditions permit. When the target area is large, smoke camouflage is typically used. Smoke camouflage is an engineering camouflage that uses smoke to obscure targets or confuse, interfere with, and lure the enemy. Because modern warfare is constantly changing and opportunities are paramount, rapidly completing camouflage in a short time is crucial for concealing deployments and improving the army's production capacity in combat. Logistics transport vehicles are among the key targets for enemy attacks and destruction during wartime. Effective camouflage of logistics transport vehicles is essential for improving their battlefield survivability and ensuring the successful completion of various transport support tasks.

[0003] Existing air-jet smoke camouflage devices have the following drawbacks: The smoke agent of existing air-jet smoke camouflage devices is usually stored in a storage tank. The smoke agent is generally made of one or more polymers, glycerin, propylene glycol, water and other additives. Different types of additives have different densities. The smoke agent stored in the storage tank for a long time may stratify, resulting in insufficient ignition and spraying of the smoke agent, which affects the viscosity, density and duration of the smoke screen. Summary of the Invention

[0004] The purpose of this invention is to provide an air-jet smoke camouflage device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gas-jet smoke screen camouflage device, comprising a storage tank and a smoke-jet pipe, wherein the storage tank has an internal movable cavity, a transmission gear is rotatably connected to the inner side wall of the movable cavity, and a first driven gear and a second driven gear are also rotatably connected to the inner side wall of the movable cavity. The first driven gear and the second driven gear are both meshed with the transmission gear, and a first driven rod and a second driven rod are respectively fixedly connected to one end of the first driven gear and the second driven gear. Spiral blades are fixedly connected to the surfaces of the first driven rod and the second driven rod.

[0006] As a preferred embodiment, a servo motor is fixedly connected to the outer wall of the storage tank, and a transmission rod is fixedly connected to the power output end of the servo motor, with one end of the transmission rod being fixedly connected to one end of the transmission gear.

[0007] As a preferred embodiment, the storage tank has a pump chamber inside, and a high-pressure pump is fixedly connected to the inner wall of the pump chamber. The inlet end of the high-pressure pump is fixedly connected to an inlet pipe, and one end of the inlet pipe extends into the storage tank. The outlet end of the high-pressure pump is fixedly connected to an outlet pipe, and the outlet pipe extends outside the pump chamber. An electronic trigger is provided on the surface of the outlet pipe. The outlet end of the outlet pipe is fixedly connected to a diverter, and the outlet end of the diverter is fixedly connected to a connecting pipe, and the outlet end of the connecting pipe is connected to the smoke spray pipe.

[0008] As a preferred embodiment, a first baffle and a second baffle are fixedly connected to the inner wall of the outlet pipe, a liquid passage cavity is formed between the first baffle and the second baffle, and liquid passage holes are uniformly arranged on the surface of both the first baffle and the second baffle. A sliding sleeve is embedded in and connected to the surface of both the first baffle and the second baffle, a sliding rod is slidably connected to the inner wall of the sliding sleeve, a stop plate is fixedly connected to the surface of the sliding rod, a rubber pad is fixedly connected to the upper surface of the stop plate, and a spring is provided between the lower surface of the stop plate and the second baffle.

[0009] As a preferred embodiment, a housing is fixedly connected to the side wall of the smoke pipe, and the surface of the housing has evenly arranged ventilation holes. A drive motor is fixedly connected to the inner side wall of the housing, and a fixing component is fixedly connected to the power output end of the drive motor. Ventilation blades are fixedly connected to the surface of the fixing component.

[0010] As a preferred embodiment, the surface of the smoke spray pipe is fixedly connected with uniformly arranged high-pressure nozzles.

[0011] As a preferred embodiment, the storage tank has an inlet on its surface, and a sealing cap is threaded onto the surface of the inlet.

[0012] As a preferred embodiment, the servo motor, high-pressure pump, drive motor, and electronic trigger are electrically connected to the vehicle's power supply via the vehicle's controller.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. The servo motor can be controlled by the transport vehicle controller. The rotation of the servo motor's power output end drives the transmission rod to rotate, which in turn drives the transmission gear to rotate. The transmission gear then drives the first driven gear and the second driven gear to rotate in opposite directions. This rotation of the first driven gear and the second driven gear drives the first driven rod and the second driven rod to rotate in opposite directions. This rotation of the first driven rod and the second driven rod drives the two spiral blades to rotate in opposite directions. The reverse rotation of the two spiral blades disrupts the symmetry of the aerosol circulation loop, increases resistance, prevents circular motion, increases turbulent motion, makes the mixing more thorough and rapid, avoids aerosol stratification, and ensures that the aerosol can burn completely.

[0015] 2. When the aerosol flows to the first baffle, it flows through the liquid passage to the stop plate. The aerosol presses against the stop plate, and flows into the liquid passage chamber. Then, it passes through the liquid passage on the second baffle and exits through the liquid outlet pipe. When the stop plate moves, it compresses the spring, putting the spring in a compressed state. When the aerosol stops flowing, the spring loses pressure and returns to its initial state. One end of the spring moves, causing the stop plate to move. The movement of the stop plate causes the rubber pad on it to move. The movement of the rubber pad forms a seal in the liquid passage chamber, which can effectively prevent the aerosol from flowing back.

[0016] 3. The smoke spray pipes are installed around the transport vehicle's cargo bed to form a surrounding smoke screen, quickly covering the vehicle. The high-pressure pump and electronic trigger can be controlled by the transport vehicle controller. The high-pressure pump creates negative pressure, causing the smoke agent in the storage tank to flow into the outlet pipe through the inlet pipe. The electronic trigger ignites the smoke agent in the outlet pipe, causing a chemical reaction that produces a large amount of smoke. The smoke flows through the outlet pipe into the connecting pipe, then into the smoke spray pipe, and finally is sprayed out by the high-pressure nozzles on the smoke spray pipe. The drive motor can be controlled by the transport vehicle controller to rotate the power output terminal, which in turn rotates the fixed components. The rotation of the fixed components rotates the ventilation blades, creating air convection that accelerates the diffusion of smoke, quickly forming a smoke screen to camouflage the transport vehicle and ensure its safety.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides, for example Figure 1-5 The device shown is a pneumatic smoke screen camouflage device, including a storage tank 1 and a smoke spray pipe 20. The storage tank 1 has a movable cavity 3 inside. A transmission gear 8 is rotatably connected to the inner side wall of the movable cavity 3. A first driven gear 9 and a second driven gear 10 are also rotatably connected to the inner side wall of the movable cavity 3. The first driven gear 9 and the second driven gear 10 are both meshed with the transmission gear 8. A first driven rod 11 and a second driven rod 12 are respectively fixedly connected to one end of the first driven gear 9 and the second driven gear 10. Spiral blades 13 are fixedly connected to the surfaces of the first driven rod 11 and the second driven rod 12. When the transmission gear 8 rotates, it drives the first driven gear 9 and the second driven gear 10 to rotate in opposite directions. The opposite rotation of the first driven gear 9 and the second driven gear 10 drives the first driven rod 11 and the second driven rod 12 to rotate in opposite directions. The opposite rotation of the first driven rod 11 and the second driven rod 12 drives the two spiral blades 13 to rotate in opposite directions. The opposite rotation of the two spiral blades 13 disrupts the symmetry of the aerosol circulation loop, increases resistance, prevents the occurrence of circular motion, increases turbulent motion, and makes the stirring more thorough and rapid, thus ensuring the complete combustion of the aerosol.

[0025] In this embodiment, a servo motor 6 is fixedly connected to the outer wall of the storage tank 1. A transmission rod 7 is fixedly connected to the power output end of the servo motor 6, and one end of the transmission rod 7 is fixedly connected to one end of the transmission gear 8. The servo motor 6 can be controlled by the control vehicle controller. The rotation of the power output end of the servo motor 6 drives the transmission rod 7 to rotate, and the rotation of the transmission rod 7 drives the transmission gear 8 to rotate. Through a series of transmissions, the smoke agent in the storage tank 1 is mixed and stirred to avoid the stratification of the smoke agent and ensure that the smoke agent can be fully burned.

[0026] In this embodiment, a pump chamber 2 is provided inside the storage tank 1. A high-pressure pump 14 is fixedly connected to the inner wall of the pump chamber 2. The inlet end of the high-pressure pump 14 is fixedly connected to an inlet pipe 15, and one end of the inlet pipe 15 extends into the storage tank 1. The outlet end of the high-pressure pump 14 is fixedly connected to an outlet pipe 16, and the outlet pipe 16 extends outside the pump chamber 2. An electronic trigger 17 is provided on the surface of the outlet pipe 16. A diverter 18 is fixedly connected to the outlet end of the outlet pipe 16. A connecting pipe 19 is fixedly connected to the outlet end of the diverter 18, and the outlet end of the connecting pipe 19 is connected to a smoke spray pipe 20. High-pressure nozzles 21 are fixedly connected to the surface of the smoke spray pipe 20. The smoke spray pipe 20 is erected... The smoke screen, which surrounds the truck bed, can quickly cover the truck when sprayed. The high-pressure pump 14 and electronic trigger 17 can be controlled by the truck controller. The high-pressure pump 14 creates a negative pressure, causing the smoke agent in the storage tank 1 to flow into the outlet pipe 16 through the inlet pipe 15. The electronic trigger 17 ignites the smoke agent in the outlet pipe 16, causing a chemical reaction that produces a large amount of smoke. The smoke flows through the outlet pipe 16 into the connecting pipe 19, then through the connecting pipe 19 into the smoke spray pipe 20, and finally is sprayed out by the high-pressure nozzles on the smoke spray pipe 20, quickly forming a smoke screen to camouflage the truck and ensure its safety.

[0027] In this embodiment, a first baffle 22 and a second baffle 23 are fixedly connected to the inner wall of the liquid outlet pipe 16. A liquid passage cavity 29 is formed between the first baffle 22 and the second baffle 23. Liquid passage holes 24 are evenly arranged on the surfaces of the first baffle 22 and the second baffle 23. Sliding sleeves 25 are embedded in and connected to the surfaces of the first baffle 22 and the second baffle 23. A sliding rod 26 is slidably connected to the inner wall of the sliding sleeve 25. A stop plate 27 is fixedly connected to the surface of the sliding rod 26. A rubber pad 28 is fixedly connected to the upper surface of the stop plate 27. A spring 30 is provided between the lower surface of the stop plate and the second baffle 23. When the aerosol flows... When the aerosol reaches the first baffle 22, it flows through the liquid passage 24 to the stop plate 27. The aerosol presses against the stop plate 27, and flows into the liquid passage chamber 29. Then it passes through the liquid passage 24 on the second baffle 23 and exits through the liquid outlet pipe 16. When the stop plate 27 moves, it compresses the spring 30, so that the spring 30 is in a compressed state. When the aerosol stops flowing, the spring 30 loses pressure and returns to its initial state. One end of the spring 30 moves, which drives the stop plate 27 to move. The movement of the stop plate drives the rubber pad 28 on it to move. The movement of the rubber pad 28 forms a seal on the liquid passage chamber 29, which can effectively prevent the aerosol from flowing back.

[0028] In this embodiment, a housing 31 is fixedly connected to the side wall of the smoke pipe 20. The surface of the housing 31 is provided with evenly arranged ventilation holes 32. A drive motor 33 is fixedly connected to the inner side wall of the housing 31. A fixing member 34 is fixedly connected to the power output end of the drive motor 33. A ventilation blade 35 is fixedly connected to the surface of the fixing member 34. The drive motor 33 can be controlled to run by the transport vehicle controller. The rotation of the drive motor 33 drives the fixing member 34 to rotate. The rotation of the fixing member 34 drives the ventilation blade 35 to rotate. The rotation of the blades forms air convection, which accelerates the diffusion of smoke.

[0029] In this embodiment, the surface of the storage tank 1 is provided with a feed inlet 4, and a sealing cap 5 is threaded onto the surface of the feed inlet 4. The servo motor 6, high-pressure pump 14, drive motor 33 and electronic trigger 17 are electrically connected to the vehicle power supply through the controller of the transport vehicle. The operation of the servo motor 6, high-pressure pump 14, drive motor 33 and electronic trigger 17 can be controlled by the controller of the transport vehicle. The operation is simple and convenient and easy to use.

[0030] The working principle of this invention is as follows: This invention is a pneumatic smoke screen camouflage device. The servo motor 6 is controlled by a transport vehicle controller. The rotation of the servo motor 6 drives the transmission rod 7, which in turn drives the transmission gear 8. The transmission gear 8 drives the first driven gear 9 and the second driven gear 10 to rotate in opposite directions. This rotation of the first driven gear 9 and the second driven gear 10 drives the first driven rod 11 and the second driven rod 12 to rotate in opposite directions. This rotation of the first driven rod 11 and the second driven rod 12 drives the two spiral blades 13 to rotate in opposite directions. The reverse rotation of the two spiral blades 13 ensures more thorough and rapid mixing, guaranteeing complete combustion of the smoke agent. The high-pressure pump 14 and the electronic trigger 17 are controlled by the transport vehicle controller. The high-pressure pump 14 creates a negative pressure, allowing the smoke agent in the storage tank 1 to flow into the outlet pipe 16 through the inlet pipe 15. When the smoke agent reaches the first baffle 22, it flows through the liquid passage 24 to the stop plate 27. The smoke agent presses against the stop plate 27, causing the smoke agent to flow... The aerosol enters the liquid passage chamber 29 and then exits through the liquid passage hole 24 on the second baffle 23 into the liquid outlet pipe 16. When the stop plate 27 moves, it compresses the spring 30, putting the spring 30 in a compressed state. When the aerosol stops flowing, the spring 30 loses pressure and returns to its initial state. One end of the spring 30 moves, causing the stop plate 27 to move. The movement of the stop plate causes the rubber pad 28 on it to move. The movement of the rubber pad 28 forms a seal on the liquid passage chamber 29, which can effectively prevent the aerosol from flowing back. The aerosol in the liquid outlet pipe 16 can be ignited by the operation of the electronic trigger 17, which produces a large amount of smoke through a chemical reaction. The smoke enters the connecting pipe 19 through the liquid outlet pipe 16, and then enters the smoke spray pipe 20 through the connecting pipe 19. Finally, it is sprayed out by the high-pressure nozzle on the smoke spray pipe 20. The drive motor 33 can be controlled by the transport vehicle controller to drive the power output end to rotate, which in turn drives the fixing part 34 to rotate. The rotation of the fixing part 34 drives the ventilation blades 35 to rotate. The rotation of the blades forms air convection, which accelerates the diffusion of smoke and quickly forms a smoke screen to camouflage the transport vehicle and ensure its safety.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
