Description

Technical Field

[0001] This invention relates to the field of laser equipment technology, specifically to a laser device for countering unmanned aerial vehicles (UAVs). Background Technology

[0002] Anti-drone laser devices, which emit high-energy laser beams to interfere with or damage the optical sensors, navigation systems, or airframe structure of drones, are an important low-altitude security measure. The core high-power laser of such devices generates a significant amount of heat during operation, requiring efficient heat dissipation to ensure stable output power and extend device lifespan. When deployed outdoors, these devices also face challenges from adverse weather conditions such as rain, fog, and sandstorms. Rain and fog severely attenuate laser energy, significantly reducing the effective range.

[0003] In existing technologies, heat dissipation and rain protection are typically two separate systems. Heat dissipation often uses fixed fans or air ducts to directly blow air onto the heat sink, with a fixed airflow direction. Rain protection relies on simple physical shields or adding a light-transmitting protective window to the laser outlet, which not only introduces optical window losses and contamination problems but also fails to prevent interference from diffuse water mist. Currently, there is a lack of an integrated solution that can intelligently switch operating modes according to the environment, combining efficient heat dissipation with active rain / fog protection functions. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a laser device for countering drones, which can switch between "assisted high-efficiency heat dissipation" and "active rain and fog protection" modes according to the usage scenario, thereby ensuring that the device maintains optimal working condition in complex outdoor environments.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser device for countering unmanned aerial vehicles (UAVs), comprising a base, a mounting bracket mounted on the base, and a laser body mounted on the mounting bracket, and further comprising an auxiliary heat dissipation mechanism; the auxiliary heat dissipation mechanism comprises a heat sink and a blowing assembly; the heat sink is mounted on the top of the laser body, the blowing assembly is disposed above the heat sink, the blowing assembly comprises a wind cavity that can rotate relative to the laser body, and a plurality of main air nozzles disposed on the wind cavity, and when not driven by an external force, the main air nozzles face the heat sink under the action of gravity.

[0007] Preferably, the length direction of the air cavity covers the width direction of the heat sink, and the plurality of main air nozzles are arranged at equal intervals along the length direction of the air cavity.

[0008] Preferably, it further includes a rainproof air curtain mechanism; the rainproof air curtain mechanism includes a drive component for driving the air cavity to rotate; the drive component is connected to the air cavity and is used to drive the air cavity to rotate, so as to change the air outlet direction of the main air nozzle.

[0009] Preferably, the drive assembly includes a drive motor, an active take-up reel, a driven take-up reel, and a cable; the drive motor is fixedly mounted; the active take-up reel is connected to the output shaft of the drive motor, the driven take-up reel is coaxially and fixedly connected to the rotating shaft of the air chamber, and one end of the cable is connected to the active take-up reel, and the other end is connected to the driven take-up reel.

[0010] Preferably, it further includes a limiting component; the limiting component includes a swing arm that rotates with the air cavity and a fixed limiting part; the swing arm cooperates with the limiting part to limit the air cavity to a rainproof working position parallel to the laser emission path.

[0011] Preferably, it further includes a side air curtain mechanism; the side air curtain mechanism includes two side air chambers and multiple side air nozzles; the two side air chambers are respectively disposed on the left and right sides of the laser body; the side air nozzles are disposed on the side air chambers, and their air outlet direction is parallel to the laser emission path of the laser body.

[0012] Preferably, the side air curtain mechanism further includes a second air pump and a second connecting pipe; the second air pump supplies air to the two side air chambers through the second connecting pipe.

[0014] Preferably, a frame is fixedly connected to the laser body, the frame is U-shaped, and the air cavity and the side air cavity are both fixedly connected to the frame.

[0015] This invention provides a laser device for countering unmanned aerial vehicles (UAVs). It has the following beneficial effects: 1. This anti-drone laser device features a rotatable air cavity design. In clear weather or when maximum heat dissipation is required, the air cavity keeps the main nozzle facing downwards under gravity, efficiently blowing heat directly onto the heat sink to improve heat dissipation performance. When it rains or requires fog protection, the drive mechanism can quickly rotate the air cavity, turning the main nozzle forward and blowing out a high-speed, dense air curtain along the laser emission path, effectively dispersing raindrops and fog in the path and significantly improving the laser's penetration ability in adverse weather conditions.

[0016] 2. The anti-drone laser device, through the setting of the side air curtain mechanism, can work together with the forward main air curtain to form an inverted U-shaped three-dimensional air curtain barrier covering the laser output port, which has a better defense effect against interference from the side, front and above, and is especially suitable for heavy rain or strong winds and rain.

[0017] 3. This anti-drone laser device shares the same air chamber and air source for both heat dissipation and main rain protection functions. Functional switching is achieved through simple mechanical rotation, resulting in a compact structure, controllable cost, and fewer potential failure points. An independent side air curtain serves as a supplement, enhancing system redundancy and reliability. The device base integrates a power supply and wheels, allowing for rapid deployment in critical outdoor locations such as rooftops and plazas, adapting to complex security deployment needs.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] This invention provides a laser device for countering unmanned aerial vehicles (UAVs), such as... Figures 1 to 6 As shown, it includes a mobile base, a laser emitting unit, and a multi-functional airflow management unit.

[0022] The mobile base includes a base 1 with multiple casters 2 equipped with brakes at its bottom for easy movement and positioning of the equipment. The interior space of the base 1 houses a high-capacity battery or other power supply to power the entire equipment. A mounting bracket 4 is fixed to the base 1 via columns or a frame.

[0023] The core of the laser emitting unit is the laser body 3, which is securely mounted on the base 1 via a mounting bracket 4. Numerous heat sinks 6 are tightly fitted to the top of the laser body 3 to increase the heat dissipation area. A U-shaped frame 5 is fixedly mounted around the laser body 3, serving as the primary mounting carrier for the subsequent airflow management unit.

[0024] The multi-functional airflow management unit integrates an auxiliary heat dissipation mechanism, a rainproof air curtain mechanism, and a side air curtain mechanism.

[0025] The main component of the auxiliary heat dissipation mechanism is the air blowing assembly. This assembly includes a long, narrow air chamber 9, which is rotatably mounted on the top crossbeam of the U-shaped frame 5 via a pivot. Figure 1 As shown, in its natural state, due to its overall center of gravity design, the air chamber 9, through counterweight or structural asymmetry, naturally faces downwards under gravity when not subjected to external force, directly facing the heat sink 6 array below. The air chamber 9 is connected to the first air pump 7 mounted on the base 1 via the first connecting pipe 8. After the high-pressure gas provided by the first air pump 7 enters the air chamber 9, it is ejected at high speed from the equally spaced main air nozzles 10, forming a uniform air curtain that directly washes the surface of the heat sink 6, carrying away heat.

[0026] The rainproof air curtain mechanism is used to change the function of the aforementioned blowing components. For example... Figure 5 As shown, it includes a drive assembly comprising a drive motor 15 fixed to the frame 5. An active take-up reel 16 is coaxially fixed to the output shaft of the drive motor 15. A driven take-up reel 17 is coaxially fixed to the rotating shaft of the air chamber 9. A cable 18, consisting of steel wire rope, is fixed at both ends and wound around these two take-up reels. When the drive motor 15 receives a rainproof mode command and rotates, it winds or releases the cable 18, thereby pulling the air chamber 9 to rotate around its rotating shaft against gravity. To prevent over-rotation and ensure precise positioning, a limiting assembly is provided: a swing arm 19 is fixed to the rotating shaft of the air chamber 9 and rotates with it; a limiting part 20 is fixed to the frame 5 and is configured as a limiting crossbar. When the air chamber 9 rotates until the main air nozzle 10 is fully forward and the airflow direction is parallel to the laser emission path, the swing arm 19 abuts against the limiting part 20, configuring this position as the rainproof working position.

[0027] As a supplement, the side air curtain mechanism includes two side air chambers 13, which are vertically fixed on the two side arms of the U-shaped frame 5, located on the left and right sides of the light outlet of the laser body 3. Each side air chamber 13 has multiple side nozzles 14 arranged vertically, with their nozzles all facing forward and parallel to the laser beam. The two side air chambers 13 are connected to another second air pump 11 through a second connecting pipe 12.

[0028] An environmental sensing module and a central controller can also be configured. The environmental sensing module is configured with a rain sensor and a humidity sensor. When the sensors detect that the rainfall or fog concentration reaches the threshold, the controller can automatically instruct the motor to work, switch modes, and start the air pump accordingly to achieve fully automatic intelligent protection.

[0029] Working principle: Sunny Day / High-Intensity Cooling Mode: The equipment is in normal operating condition. The first air pump 7 starts, and high-pressure airflow blows vertically downwards through the main air nozzle 10 onto the heat sink 6, achieving efficient auxiliary forced air cooling. At this time, the rainproof air curtain mechanism is not activated, the cable 18 is in a slack state, and the side air curtain mechanism is normally closed.

[0030] Light rain / fog / rainproof mode: Operators manually switch between these modes. The control system first instructs the drive motor 15 to operate, which, via the cable 18, smoothly rotates the air chamber 9 from its downward heat dissipation position to its forward rainproof position, precisely positioned by the swing arm 19 and the limiting part 20. At this time, the air outlet direction of the main air nozzle 10 changes to forward along the laser emission path. The first air pump 7 continues to operate, and the high-speed airflow it emits forms an air curtain in front of the laser beam, effectively dispersing and blocking raindrops and fog in the path, reducing their attenuation of laser energy.

[0031] Heavy rain / strong crosswind weather / three-dimensional protection mode: Based on the activation of the forward main air curtain, the second air pump 11 is further activated to supply air to the two side air chambers 13. The side air nozzles 14 spray air forward, which connects spatially with the air curtain generated by the main air nozzles 10 to form a stronger "inverted U-shaped" three-dimensional air curtain barrier, providing more comprehensive protection.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
