Description

Technical Field

[0001] This utility model relates to the field of smoke generating equipment, specifically to a smoke screen releasing device. Background Technology

[0002] With the development of unmanned and intelligent equipment, more and more unmanned combat platforms will appear on the future battlefield. To improve their survivability on the battlefield, long-duration, continuous, large-area smoke screen equipment that can be mounted on unmanned platforms is needed. Currently, most smoke-generating equipment weighs between 30kg and 35kg. This equipment needs to be able to continuously release smoke screens that block visible light or interfere with near-infrared radiation for 5 to 10 minutes, ideally portable by a single soldier or vehicle-mounted. Existing domestic smoke-generating equipment mainly includes smoke canisters, smoke vehicles, and smoke grenades. The smoke generator mounted on the smoke vehicle typically includes a turbojet engine. The turbojet engine is a portable hot airflow generator suitable for vehicles, ships, boats, and other transport platforms. It mainly consists of the engine body, control box, engine oil filter, and accessories such as pipelines and valves. The smoke generator is mainly used for ground-based vehicle-mounted smoke screen deployment to protect large targets. Existing equipment is large in size and weight, and the assembly and disassembly are complex. Its adaptability and mobility do not meet the requirements for rapid deployment on unmanned combat platforms and portable use by a single soldier. Therefore, there is a need to provide a miniaturized smoke-generating device that produces uniform smoke. Utility Model Content

[0003] The present invention aims to provide a smoke screen release device, which provides a miniaturized smoke screen generating device that produces uniform smoke.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a smoke screen release device, comprising a turbojet engine, a smoke oil pump, and a nozzle section, wherein the smoke oil pump is connected to the nozzle section, the turbojet engine provides high-temperature and high-speed gas flow to the nozzle section, the nozzle section includes a flared nozzle and a smoke oil nozzle, a smoke oil ring pipe is fixedly sleeved on the outside of the smoke oil nozzle, an annular cavity is formed between the smoke oil ring pipe and the smoke oil nozzle, and a plurality of nozzles communicating with the annular cavity are arranged circumferentially on the inner wall of the smoke oil nozzle.

[0005] The beneficial effects of this plan are:

[0006] The fuel tank is connected to the turbojet engine. Fuel is injected and burned by the turbojet engine, generating high-temperature, high-speed combustion gases that are fed into the nozzle. Simultaneously, the fumes pump is connected to the nozzle, ensuring that the fumes and atomized fumes are thoroughly mixed with the high-temperature, high-speed combustion gases before forming a smoke screen and being discharged, creating a high-performance smoke barrier in the air. The flared nozzle has a smooth surface, preventing fumes from accumulating. A fumes ring tube is fitted outside the fumes nozzle, forming an annular cavity. The fumes are evenly distributed through this annular cavity to multiple nozzles circumferentially distributed on the inner wall of the nozzle. These nozzles atomize the fumes and spray them evenly into the flared nozzle. The evenly distributed nozzles and the annular cavity ensure thorough mixing of the fumes with the high-temperature, high-speed combustion gases, enhancing the smoke screen's shielding effectiveness.

[0007] Preferably, as an improvement, the surfaces of the e-liquid spray pipe and the flared spray pipe are each provided with a first flange, and the two first flanges are fixed relative to each other to achieve a sealed connection between the flared spray pipe and the e-liquid spray pipe.

[0008] The beneficial effects are: the flared nozzle and the e-liquid nozzle are fixedly connected by the first flange, ensuring the sealing of the connection and preventing oil leakage when the smoke screen is released.

[0009] Preferably, as an improvement, the e-liquid ring tube includes a semi-circular ring tube and connecting rings located on both sides of the semi-circular ring tube, and the connecting rings are sealed and fixedly connected to the e-liquid spray tube.

[0010] The beneficial effects are as follows: the semi-circular tube provides a smooth flow path for the e-liquid, reduces the resistance in the e-liquid flow, and makes the e-liquid evenly distributed within the circular range. The addition of the connecting ring increases the fixing area with the e-liquid nozzle, ensuring its stability. The sealed and fixed connection between the connecting ring and the e-liquid nozzle can effectively prevent e-liquid leakage between nozzle components, so that the system can maintain stable performance after long-term operation and avoid adverse effects on the equipment caused by oil or gas leakage.

[0011] Preferably, as an improvement, it also includes an e-liquid pipe for connecting the e-liquid pump and the annular cavity, with a one-way valve in the middle of the e-liquid pipe, and the e-liquid pump is a self-priming high-pressure, high-flow e-liquid pump.

[0012] The beneficial effects are as follows: The self-priming high-pressure, high-flow oil pump motor is integrated with the oil pump, which has the advantages of high torque, low noise, and small size. This allows the e-liquid pump to quickly draw in e-liquid without external pressure, ensuring the stability and continuity of the oil supply. By setting a one-way valve, it is ensured that the e-liquid can only flow in one direction, preventing backflow of e-liquid from contaminating the e-liquid pump or other components, keeping the equipment clean and functionally stable, and ensuring the stable operation of the e-liquid pump. The above equipment is compact in size, making it easy for individual soldiers to carry and install on small unmanned combat platforms.

[0013] Preferably, as an improvement, the turbojet engine includes an oil inlet, a turbine section, an electric motor section, and an exhaust nozzle section arranged in sequence, with the exhaust nozzle section opposite to the smoke and oil spray pipe.

[0014] Preferably, as an improvement, it also includes a connecting pipe, on the surface of the connecting pipe opposite to the e-liquid spray pipe, a second flange is provided, the two second flanges are opposite each other and fixed by bolts, and the tail spray is inserted into the connecting pipe.

[0015] The beneficial effects are as follows: By inserting the tail nozzle into the connecting pipe through the above-mentioned configuration, and connecting the connecting pipe to the smoke and oil spray pipe, the high-speed, high-temperature gas generated by the turbojet engine can be fully integrated into the smoke and oil spray pipe, ensuring its thorough mixing with the smoke and oil. This ensures efficient interaction between the gas and smoke and oil in the spray pipe, improving the smoke effect. Inserting the tail nozzle into the connecting pipe and fixing it with the second flange not only enhances the stability of the connection but also effectively prevents loosening caused by vibration or improper operation. The bolt connection ensures the tight fixation of the components, and the connection will not loosen due to overheating or airflow impact, increasing the durability of the equipment and the reliability of long-term operation, and enhancing the mechanical reliability of the entire device.

[0016] Preferably, as an improvement, the number of nozzles is six. Attached Figure Description

[0018] Figure 2 This is a schematic diagram of the structure of the e-liquid pump according to an embodiment of the present utility model. Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method:

[0020] The reference numerals in the accompanying drawings include: turbojet engine 1, smoke oil pump 2, flared nozzle 3, smoke oil nozzle 4, tail nozzle 5, annular cavity 6, nozzle 7, first flange 8, semi-circular annular pipe 9, connecting ring 10, smoke oil pipe 11, one-way valve 12, connecting pipe 13, bolt 14, and second flange 15.

[0021] Example

[0022] The implementation examples are basically as follows Figures 1-2 As shown, Figure 1The smoke screen dispensing device shown includes a turbojet engine 1, a smoke oil pump 2, a fuel supply unit, and a nozzle unit. The smoke oil pump 2 is connected to the nozzle unit. The fuel supply unit includes a smoke oil tank and a fuel tank. The fuel tank is connected to the turbojet engine 1. The turbojet engine 1 provides a high-temperature, high-speed gas flow to the nozzle unit. The nozzle unit includes a flared nozzle 3 and a smoke oil nozzle 4. A smoke oil ring pipe is fixedly sleeved on the outside of the smoke oil nozzle 4. An annular cavity 6 is formed between the smoke oil ring pipe and the smoke oil nozzle 4. Multiple nozzles 7 connected to the annular cavity 6 are arranged circumferentially on the inner wall of the smoke oil nozzle 4. The smoke oil is atomized into smoke oil through the nozzles 7. In this embodiment, the number of nozzles 7 is six to ensure that the smoke oil is evenly distributed circumferentially in the smoke oil nozzle 4. The fuel tank is connected to the turbojet engine 1. Fuel is injected and burned by the turbojet engine 1, generating high-temperature, high-speed combustion gases that are introduced into the nozzle section. Simultaneously, the fumes pump 2 is connected to the nozzle section, ensuring that the fumes and atomized fumes are fully mixed with the high-temperature, high-speed combustion gases in the nozzle section before forming a smoke screen and being discharged, creating a high-performance smoke screen in the air. The flared nozzle 3 has a smooth surface, preventing fumes from accumulating. A fumes ring tube is fitted outside the fumes nozzle 4, forming an annular cavity 6. The fumes are evenly distributed through the annular cavity 6 to multiple nozzles 7 circumferentially distributed on the inner wall of the nozzle. The nozzles 7 atomize the fumes and spray them evenly into the flared nozzle 3. The evenly distributed nozzles 7 and the annular cavity 6 ensure thorough mixing of the fumes and high-temperature, high-speed combustion gases, improving the smoke screen's obstruction and effectiveness.

[0023] Both the e-liquid nozzle 4 and the flared nozzle 3 have a first flange 8 on their opposing surfaces. The two first flanges 8 are fixedly positioned relative to each other to achieve a sealed connection between the flared nozzle 3 and the e-liquid nozzle 4. The flared nozzle 3 and the e-liquid nozzle 4 are fixedly connected by the first flanges 8 to ensure the sealing of the connection, preventing oil leakage during smoke screen release; Figure 1As shown, the e-liquid ring tube in this embodiment includes a semi-circular ring tube 9 and connecting rings 10 located on both sides of the semi-circular ring tube 9. The connecting rings 10 are sealed and fixedly connected to the e-liquid nozzle 4. The semi-circular ring tube 9 provides a smooth flow path for the e-liquid, reduces the resistance in the e-liquid flow, and makes the e-liquid evenly distributed in the ring range. Increasing the connecting rings 10 can increase the fixing area with the e-liquid nozzle 4, ensuring its fixing stability. The sealed and fixed connection between the connecting rings 10 and the e-liquid nozzle 4 can effectively prevent the e-liquid from leaking between the nozzle components, so that the system can still maintain stable performance after long-term operation, and avoid the adverse effects of oil or gas leakage on the equipment. It also includes an e-liquid pipe 11 for connecting the e-liquid pump 2 and the annular cavity 6. The e-liquid pipe 11 is also equipped with a one-way valve 12 in the middle. The e-liquid pump 2 is a self-priming high-pressure high-flow oil pump. The self-priming high-pressure high-flow oil pump motor is integrated with the oil pump, which has the advantages of high torque, low noise and small size. This allows the e-liquid pump 2 to quickly draw in e-liquid without external pressure, ensuring the stability and continuity of oil supply. By setting the one-way valve 12, it is ensured that the e-liquid can only flow in one direction, preventing the e-liquid from flowing back and contaminating the e-liquid pump 2 or other components, keeping the equipment clean and functionally stable, and ensuring the stable operation of the e-liquid pump 2. The above equipment is small in size, making it easy for a single soldier to carry and install on a small unmanned combat platform.

[0024] The turbojet engine 1 includes an oil inlet, a turbine section, a motor section, and a tail nozzle 5 arranged sequentially. The tail nozzle 5 is a conical nozzle facing the smoke and oil spray pipe 4. It also includes a connecting pipe 13. The surfaces of the connecting pipe 13 facing the smoke and oil spray pipe 4 are provided with second flanges 15. The two second flanges 15 are facing each other and fixed by bolts 14. The tail nozzle 5 is inserted into the connecting pipe 13. By inserting the tail nozzle 5 into the connecting pipe 13 through the above arrangement, the connecting pipe 13 is connected to the smoke and oil spray pipe 4, which can fully integrate the high-speed and high-temperature gas generated by the turbojet engine 1 into the smoke and oil spray pipe 4, ensuring that it is fully mixed with the smoke and oil. This ensures efficient interaction between the gas and smoke and oil in the spray pipe section, improving the smoke effect. By inserting the tail nozzle 5 into the connecting pipe 13 and fixing it with the second flanges 15, not only is the connection stability enhanced, but loosening caused by vibration or improper operation is also effectively avoided. The connection by bolts 14 ensures tight fixing of the components. The connection part will not loosen due to overheating or airflow impact, increasing the durability of the equipment and the reliability of long-term operation, and enhancing the mechanical reliability of the entire device.
