Description

Technical Field

[0001] This utility model relates to the field of warning device technology, and in particular to a drone warning light device for use at highway accident scenes. Background Technology

[0002] In the field of highway transportation, after a traffic accident, to prevent secondary accidents caused by passing vehicles failing to notice the accident scene in time, it is necessary to set up warning devices around the accident site. Currently, the most common warning methods are placing warning triangles and turning on vehicle hazard lights. With the rapid development of drone technology, drones are increasingly being used in emergency rescue. Utilizing the rapid deployment capabilities of drones, combined with high-brightness warning lights, an aerial warning zone can be formed, eliminating the need for rescue personnel to manually place warning devices and significantly shortening the time required to form a warning zone.

[0003] For example, Chinese patent CN221394094U discloses a device for mounting high-voltage line warning lights on a drone, including a drone body and a connecting plate. A fixing plate is bolted to the lower surface of the drone body, and lifting rings are fixedly connected to the four corners of the lower surface of the fixing plate. Connecting seats are fixedly connected to the four corners of the upper surface of the connecting plate. By setting lifting rings at the lower end of the drone body and hooks on the connecting plate, the warning device can be mounted on the drone body through the interaction of the hooks and lifting rings. The device, equipped with a buzzer, a warning light body, and a warning sign, can achieve the warning function, enabling high-altitude warning via the drone body. It can be quickly deployed where needed, has a wider coverage area, and is highly flexible, allowing it to be moved to the location requiring warning at any time, thus improving the mobility of the high-voltage line warning light device.

[0004] However, since the warning light body is located on the upper surface of the skateboard, the skateboard partially obstructs the light-emitting surface of the warning light body. Especially when the warning light body needs to radiate warning light to the side or downward, the obstruction of the skateboard will directly weaken the range and intensity of light propagation, causing the warning signal to be unable to be clearly received by surrounding vehicles or people, which seriously affects the warning effect of the warning device.

[0028] Example 1:

[0029] This utility model embodiment provides a drone warning light device for use at highway accident scenes, such as... Figures 1-5As shown, it includes: a drone body 1 and a warning light body 2. The drone body 1 includes a fuselage shell 3. A mounting plate 4 is provided below the fuselage shell 3. The mounting plate 4 is detachably connected to the fuselage shell 3 through a connecting mechanism. A mounting hole 5 is provided in the center of the mounting plate 4. The warning light body 2 is placed in the mounting hole 5. A clamping mechanism is provided on the mounting plate 4. The clamping mechanism includes a fixing block 6. The fixing block 6 is located in front of the warning light body 2. A sliding hole is provided in the fixing block 6. A clamping rod 7 is slidably arranged in the sliding hole. A clamping block 8 is provided at one end of the clamping rod 7 near the warning light body 2. The clamping block 8 contacts the outer wall of the warning light body 2. A return spring 9 is sleeved on the outside of the clamping rod 7. One end of the return spring 9 is connected to the clamping block 8. The other end of the return spring 9 is connected to the fixing block 6. The end of the clamping rod 7 away from the warning light body 2 extends to the front of the fixing block 6 and is provided with a pull rod 10.

[0030] The diameter of the warning light body 2 is smaller than the diameter of the mounting hole 5;

[0031] A baffle 11 is fixedly installed on the upper end of the warning light body 2, and the diameter of the baffle 11 is larger than the diameter of the mounting hole 5;

[0032] The clamping block 8 is arc-shaped, and the side of the clamping block 8 closest to the warning light body 2 is adapted to the outer wall of the warning light body 2.

[0033] The working principle and beneficial effects of the above technical solution are as follows: Initially, the mounting plate 4 separates from the fuselage shell 3, which does not increase the load on the drone body 1. When the drone body 1 is used without warning operations, it does not increase the energy consumption of the drone body 1, ensuring the endurance of the drone body 1. When a road accident occurs and a warning is needed, first pull the lever 10 forward, causing the clamping lever 7 to move away from the mounting hole 5. The return spring 9 is compressed, and the clamping block 8 moves away from the mounting hole 5, increasing the space at the upper end of the mounting hole 5. Then, the luminous area of ​​the warning light body 2 is inserted into the mounting hole 5 with the luminous area facing down. The warning light body 2 uses an existing traffic warning light with a built-in battery. The lower end of the lamp body 2 passes through the mounting hole 5 until the luminous area of ​​the warning lamp body 2 is completely below the mounting plate 4. Then, the pull rod 10 is released. Under the action of the return spring 9, the clamping rod 7 moves the clamping block 8 towards the warning lamp body 2 until the arc-shaped inner wall of the clamping block 8 is tightly fitted with the outer wall of the warning lamp body 2. At this time, the installation of the warning lamp body 2 is completed. The clamping block 8 is made of elastic non-slip rubber material. On the one hand, it will not damage the outer wall of the warning lamp body 2. On the other hand, it can radially fix the warning lamp body 2 through friction, preventing the warning lamp body 2 from slipping out of the mounting hole 5. A baffle 11 is fixedly installed at the upper end of the warning lamp body 2. The clamping block 8 holds the warning lamp body 2 in place. After the body 2 is clamped, the lower surface of the baffle 11 contacts the upper surface of the clamping block 8. Since the diameter of the baffle 11 is larger than the diameter of the mounting hole 5, the baffle 11 can axially limit the warning light body 2, preventing the warning light body 2 from falling downward from the mounting hole 5, further improving the reliability of the warning light body 2. After the warning light body 2 is installed, the mounting plate 4 is connected to the fuselage shell 3 of the drone body 1 through the connecting mechanism. Then, the warning light body 2 is turned on, and the drone body 1 is started. The drone body 1 can then carry the warning light body 2 and quickly fly to the airspace above the highway accident scene and hover. Since the warning light body 2 is directly installed in the mounting hole 5 of the mounting plate 4, the warning light body 2... The luminous area is not obstructed by the mounting plate 4 or other structures, and the warning light emitted can radiate unobstructed to the sides, down and surrounding areas, forming a complete three-dimensional warning area, which enhances the warning effect. Passing vehicles can clearly receive the warning signal and avoid it in time, reducing the risk of secondary accidents caused by obstruction of the warning signal. When the warning function is not needed or the warning light body 2 needs to be charged or maintained, the operator first removes the mounting plate 4 from the outer shell 3, and then pulls the lever 10 again to make the clamp 8 disengage from the outer wall of the warning light body 2, releasing the radial fixation of the warning light body 2. Then the warning light body 2 can be taken out from the mounting hole 5 upwards, which is convenient and quick.

[0034] Example 2:

[0035] Based on the above embodiment 1, as follows Figure 1As shown, a transparent protective cover 12 is provided at the bottom of the mounting plate 4. The upper end of the transparent protective cover 12 is fixedly connected to the lower surface of the mounting plate 4. The central axis of the transparent protective cover 12 is on the same straight line as the central axis of the mounting hole 5.

[0036] The working principle and beneficial effects of the above technical solution are as follows: the diameter of the transparent protective cover 12 is larger than the diameter of the warning light body 2. The transparent protective cover 12 is made of transparent materials such as polyvinyl chloride and acrylic. The transparent protective cover 12 can protect the warning light body 2 and prevent external debris such as airflow, dust, and gravel from directly contacting the warning light body 2, thereby extending the service life of the warning light body 2.

[0037] Example 3:

[0038] Based on Example 1 or 2, such as Figures 1-5 As shown, the connecting mechanism includes two fixed plates 13, which are symmetrically arranged on the left and right sides of the upper surface of the mounting plate 4. The fixed plates 13 are fixedly connected to the mounting plate 4. A double-headed screw 14 is rotatably arranged between the two fixed plates 13. A turntable 15 is arranged at the center of the double-headed screw 14. The threads at both ends of the double-headed screw 14 have opposite directions. Clamping plates 16 are threaded to both ends of the double-headed screw 14. The lower surface of the clamping plate 16 is slidably connected to the slide rail 17. The slide rail 17 is fixedly arranged on the upper surface of the mounting plate 4.

[0039] A first anti-slip plate 18 is fixedly installed on the side of the clamping plate 16 near the warning light body 2;

[0040] A rotating hole 19 is provided at the upper end of the clamping plate 16. A first screw 20 is provided in the rotating hole 19. The upper end of the first screw 20 extends to the top of the rotating hole 19 and is provided with a knob. The lower end of the first screw 20 is rotatably connected to the bottom wall of the rotating hole 19. A slide groove 21 is provided on the side of the clamping plate 16 near the warning light body 2. One side of the slide groove 21 is connected to the inside of the rotating hole 19. A slider 22 is provided on the first screw 20. The slider 22 is threadedly connected to the outer wall of the first screw 20 through a first threaded hole. One end of the slider 22 extends to the outside of the slide groove 21 and is provided with a pressure plate 23. The slider 22 is slidably connected to the inner wall of the slide groove 21.

[0041] A second anti-slip plate 24 is fixedly installed on the lower surface of the pressure plate 23;

[0042] The side wall of the clamping plate 16 is provided with a second threaded hole, one end of which is connected to the rotating hole 19. A tightening bolt 25 is provided on the outside of the clamping plate 16, and one end of the tightening bolt 25 is connected to the inner wall of the second threaded hole via thread transmission.

[0043] The working principle and beneficial effects of the above technical solution are as follows: When installing the mounting plate 4, first place the mounting plate 4 directly below the fuselage shell 3 of the UAV body 1, so that the two clamping plates 16 are located on both sides of the fuselage shell 3. Then move the mounting plate 4 upward until the baffle 11 contacts the lower surface of the fuselage shell 3. The two ends of the double-headed screw 14 are respectively rotatably connected to the fixing plate 13. Rotate the turntable 15. The rotation of the turntable 15 drives the double-headed screw 14 to rotate. The clamping plates 16 can then slide along the slide rail 17 on the upper surface of the mounting plate 4 in a direction that moves closer to each other. As the clamping plates 16 gradually move closer to each other... Near the fuselage shell 3, the first anti-slip plate 18 on the inner side of the clamping plate 16 is tightly fitted to the side wall of the fuselage shell 3. The friction between the first anti-slip plate 18 and the fuselage shell 3 forms a lateral clamping force, completing the initial lateral fixation of the mounting plate 4 to the fuselage shell 3 and preventing the mounting plate 4 from shifting in the horizontal direction. Then, the knob is turned, which drives the first screw 20 to rotate in the rotating hole 19. The rotation of the first screw 20 drives the slider 22 to slide downward along the inner wall of the slide groove 21. The slider 22 drives the pressure plate 23 to move closer to the upper surface of the fuselage shell 3 until the pressure plate... The second anti-slip plate 24 on the lower surface of the 23 makes tight contact with the upper surface of the fuselage shell 3, forming a longitudinal clamping force. Then, rotating the tightening bolt 25 can lock the first screw 20, preventing the first screw 20 from rotating arbitrarily. Through the contact between the first anti-slip plate 18, the second anti-slip plate 24 and the fuselage shell 3, the mounting plate 4 is fixed both laterally and longitudinally, further improving the stability of the connection between the mounting plate 4 and the fuselage shell 3. Both the first anti-slip plate 18 and the second anti-slip plate 24 are made of anti-slip rubber material, which can increase friction and prevent the drone body 1 from flying over During the process, vibration or airflow impact may cause the mounting plate 4 to loosen or shift, further improving the stability of the warning light body 2, thereby ensuring the warning effect of the warning light device; when removing the mounting plate 4, first loosen the tightening bolt 25, then turn the knob in the opposite direction to separate the second anti-slip plate 24 from the upper surface of the body shell 3, then turn the turntable 15 in the opposite direction to make the side clamps 16 slide away from the body shell 3, and the first anti-slip plate 18 separate from the body shell 3, so that the mounting plate 4 can be removed from the bottom of the body shell 3, thereby achieving quick removal of the mounting plate 4.
