Description

Technical Field

[0001] The present invention relates to the technical field of industrial lighting fixtures, and in particular to a warning light suitable for installation on a drone and an installation method thereof. Background Art

[0002] Warning lights are usually installed in outdoor high-altitude buildings to achieve high-altitude warning. Since outdoor high-altitude buildings are high (up to hundreds of meters), it is difficult to mount warning lights in the air using ordinary engineering machinery, which is difficult to operate, and it takes a lot of time and cost.

[0003] Using drones to mount warning lights on high-altitude buildings is a feasible way. The warning light is mounted on a drone, the drone is launched, and the warning light is sent to the designated target location, and the warning light is clamped on the high-altitude building by the clamp equipped on the warning light. This method of using drones to mount warning lights on high-altitude buildings is simple, efficient, and time-saving.

[0004] The clamps equipped with traditional warning lights mainly use clip clamping to achieve the installation of the warning light. The left and right clips are clamped to each other by the torque provided by the torsion spring. However, the force provided by the torsion spring is limited. The left and right clips are very easy to fall from a high altitude, which is very dangerous.

[0005] In order to improve the installation stability of the warning light, engineers tried to use thread locking instead of the traditional torsion spring clamping method. This is because thread locking has higher stability and is not easy to make the clamp loose. Engineers also encountered difficulties in the structural design of thread locking. On the one hand, rotation is required during thread locking, which is very time-consuming. On the other hand, further tightening is required after thread locking to prevent the thread from loosening. However, since it is a high-altitude operation scenario based on drones (not as simple as manually tightening screws on the ground), specific problems need to be analyzed specifically to design and develop a warning light suitable for drone installation and its installation method. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a warning light suitable for installation on a drone and an installation method thereof.

[0044] like Figure 1 As shown, the present invention discloses a warning light 10 suitable for installation on a drone, comprising a light body 20 and a clamping claw assembly 30. The light body 20 and the clamping claw assembly 30 are connected via an intermediate connecting rod 40.

[0045] like Figure 2 As shown, the clamping jaw assembly 30 includes: a base 100, a left clamping jaw 200, a right clamping jaw 300, a threaded column 400, and a trigger rod 500. The left clamping jaw 200 and the right clamping jaw 300 are rotatably arranged on the base 100 through a torsion spring (not shown in the figure), the threaded column 400 is installed on the base 100 and is located between the left clamping jaw 200 and the right clamping jaw 300, and the left clamping jaw 200 and the right clamping jaw 300 are respectively provided with a threaded structure 201 that is screwed with the threaded column 400; the trigger rod 500 is telescopically and movably arranged on the threaded column 400, and a supporting block 501 (such as Figure 3 and Figure 4 The left clamping jaw 200 and the right clamping jaw 300 are respectively provided with a pressing block 202 (as shown in Figure 3 and Figure 4 shown).

[0046] like Figure 3 As shown, when the abutting block 501 and the pressing block 202 are engaged with each other, the left clamping jaw 200 and the right clamping jaw 300 are separated from each other, and the threaded structure 400 is separated from the threaded column 400; Figure 4As shown, the trigger rod 500 is pressed to separate the abutting block 501 and the pressing block 202 from each other, and the left clamping jaw 200 and the right clamping jaw 300 are clamped together under the action of the torsion spring, and at the same time, the threaded structure 201 and the threaded column 400 are screwed together.

[0047] like Figure 3 and Figure 4 As shown, in this embodiment, a receiving cavity 401 is opened on the central axis of the threaded column 400, and the trigger rod 500 can be elastically and movably sleeved on the threaded column 400 through a trigger spring 502, and one end of the trigger rod 500 is exposed outside the receiving cavity 401 to form a trigger end 503.

[0048] like Figure 5 As shown, the warning light 10 suitable for installation in a drone further includes a tightening device 600 for further tightening the threaded structure 201 and the threaded column 400. The threaded column 400 is rotatably disposed on the base 100.

[0049] like Figure 6 As shown, the tightening device 600 includes: a clutch assembly 610 , a spring assembly 620 , a one-way ratchet 630 , and a speed-changing gear set 640 .

[0050] like Figure 6 and Figure 7 As shown, the clutch assembly 610 is disposed on the middle connecting rod 40 , and the clutch assembly 610 is clutch-connected with the spring assembly 620 , and the spring assembly 620 is unidirectionally drivenly connected with the speed change gear set 640 through the one-way ratchet 630 , and the speed change gear set 640 is connected with the threaded column 400 .

[0051] like Figure 6 , Figure 7 and Figure 8 As shown, the clutch assembly 610 is connected to the spring assembly 620 and drives it to rotate in the forward direction. The forward rotating spring assembly 620 stores elastic potential energy, and the one-way ratchet 630 rotates in the forward direction following the spring assembly 620 without driving the speed change gear set 640.

[0052] like Figure 6 , Figure 7 and Fig. 9 As shown, the clutch assembly 610 is separated from the spring assembly 620, the spring assembly 620 rotates in the opposite direction and releases elastic potential energy, the one-way ratchet 630 rotates in the opposite direction following the spring assembly 320 to drive the speed change gear set 640, and the speed change gear set 640 drives the threaded column 400 to rotate rapidly so that the threaded structure 201 and the threaded column 400 are further locked.

[0053] like Figure 6 and Figure 7As shown, specifically, the clockwork assembly 620 includes: a clockwork body 621, a central shaft 622, and a fixed ring 623. The central shaft 622 is disposed at the center of the clockwork body 621, and the fixed ring 623 is disposed at the outer edge of the clockwork body 621; wherein the fixed ring 623 is fixed on the base 100, and the one-way ratchet 630 is disposed on the central shaft 622.

[0054] like Figure 6 and Figure 7 As shown, specifically, the clutch assembly 610 includes a clutch sleeve 611 ; the clutch sleeve 611 is disposed at one end of the middle connecting rod 40 , and the clutch sleeve 611 is clutch-connected to the central rotating shaft 622 .

[0055] like Figure 6 and Figure 7 As shown, further, the clutch assembly 610 also includes a clutch spring 612 , and the clutch sleeve 611 is elastically and movably disposed at one end of the middle connecting rod 40 through the clutch spring 612 .

[0056] like Figure 6 and Figure 7 As shown, specifically, the speed change gear set 640 includes: a ring gear 641 and a planetary wheel 642. The ring gear 641 and the planetary wheel 642 are rotatably arranged on the base 100, and the inner ring of the ring gear 641 is meshed with the threaded column 400 through the planetary wheel 642; the one-way ratchet 630 drives the ring gear 641 to rotate, and the ring gear 641 further drives the threaded column 400 to rotate through the planetary wheel 642.

[0057] Next, the working principle and usage of the warning light 10 suitable for installation on a drone are described (please refer to Fig.10 ):

[0058] like Figure 3 As shown, the lamp body 20 is placed on the drone 50 (the drone 50 may be provided with a receiving groove for placing the lamp body 20), at this time, the abutting block 501 and the pressing block 202 are mutually engaged, the left clamping jaw 200 and the right clamping jaw 300 are separated from each other, and the threaded structure 201 is separated from the threaded column 400; the left clamping jaw 200 and the right clamping jaw 300 are broken apart to separate them from each other, and the abutting block 501 and the pressing block 202 are mutually engaged to prevent the left clamping jaw 200 and the right clamping jaw 300 from being clamped again under the action of the torsion spring;

[0059] The drone 50 is lifted into the air, so that the lamp body 20 approaches the mounted object 60;

[0060] like Figure 4As shown, when the lamp body 20 approaches the mount 60, its trigger rod 500 will first touch the mount 60 and be triggered, the abutting block 501 and the pressing block 202 will separate from each other, the left clamping jaw 200 and the right clamping jaw 300 will clamp each other under the action of the torsion spring, and at the same time, the threaded structure 201 and the threaded column 400 will be screwed together; in this process, the problem of needing to twist the thread for a long time is solved, which is simple and efficient; however, this is only the initial locking of the thread, and the threaded structure 201 and the threaded column 400 are still in a relatively loose state. If they are not tightened further, the threaded column 400 is easily affected by the outside world and reversed, affecting the stability of the connection;

[0061] like Figure 6 , Figure 7 and Figure 8 As shown, the clutch assembly 610 is connected to the spring assembly 620, the drone 50 rotates, and the lamp body 20 rotates accordingly. The lamp body 20 drives the clutch assembly 610 to rotate forwardly through the intermediate connecting rod 40, and the clutch assembly 610 drives the spring assembly 620 to rotate forwardly. The spring assembly 620 that rotates forwardly stores elastic potential energy, and the one-way ratchet 630 rotates forwardly with the spring assembly 620 without driving the speed change gear set 640. In this process, the drone 50 rotates itself and the various structures mutually move to realize that the spring assembly 620 can store elastic potential energy, and provides "instantaneous torque" for the subsequent spring assembly 620 to suddenly release the elastic potential energy to realize the locking of the threaded structure and the threaded column. The present invention particularly introduces the one-way ratchet 630, which has a unidirectional driving force. In the process of the spring assembly 620 storing elastic potential energy, the one-way ratchet 630 will not drive the speed change gear set 640 to rotate, which is very important.

[0062] like Figure 6 , Figure 7 and Fig. 9 As shown, the drone 50 suddenly drops and separates from the lamp body 20. Under the action of gravity, the clutch assembly 610 separates from the spring assembly 620. The spring assembly 620 rotates in the opposite direction and releases elastic potential energy. The one-way ratchet 630 rotates in the opposite direction following the spring assembly 620 to drive the speed change gear set 640. The speed change gear set 640 drives the threaded column 400 to rotate rapidly, so that the threaded structure 201 and the threaded column 400 are further locked. In this process, the spring assembly 620 suddenly releases elastic potential energy and provides "instantaneous torque". Only "instantaneous torque" can more effectively achieve the locking of the threaded structure 201 and the threaded column 400. It can be understood that it is equivalent to the daily screwing operation of people. In the final stage, it is necessary to provide a quick torque by hand. Only in this way can the screw be locked more firmly. In the process of high-altitude operation, if the drone rotates alone, it is impossible to provide this "instantaneous torque" and achieve a good tightening effect.

[0063] The present invention also discloses a method for installing a warning light, based on the above-mentioned warning light suitable for installation on a drone, the lamp body is installed on a high-altitude mount 60 through a drone 50;

[0064] The steps include:

[0065] Step 1: Place the lamp body on the drone. At this time, the abutting block and the pressing block are engaged with each other, the left clamping jaw and the right clamping jaw are separated from each other, and the threaded structure is separated from the threaded column.

[0066] Step 2: The drone is launched into the air, so that the lamp body approaches the mount;

[0067] Step 3: The trigger rod touches the mounted object and is triggered, the abutting block and the pressing block are separated from each other, the left clamping jaw and the right clamping jaw are clamped together under the action of the torsion spring, and the threaded structure and the threaded column are screwed together;

[0068] Step 4: The clutch assembly is connected to the spring assembly, the drone rotates, the lamp body rotates with it, the lamp body drives the clutch assembly to rotate forward through the middle connecting rod, the clutch assembly drives the spring assembly to rotate forward, the forward rotating spring assembly stores elastic potential energy, and the one-way ratchet follows the spring assembly to rotate forward without driving the speed change gear set;

[0069] Step 5: The drone descends and separates from the lamp body. Under the action of gravity, the clutch assembly separates from the clockwork assembly, the clockwork assembly rotates in the opposite direction and releases elastic potential energy, the one-way ratchet follows the clockwork assembly to rotate in the opposite direction and drives the speed change gear set, and the speed change gear set drives the threaded column to rotate rapidly, so that the threaded structure and the threaded column are further locked.

[0070] Here, the above-mentioned clutch spring 612 needs to be explained (please also refer to Figure 8 and Fig. 9 ), in step 4, during high-altitude operations, if the clutch assembly and the clockwork assembly have not been connected together, based on the lifting force of the drone, the clutch spring 612 will be in a compressed state, and a resisting force will be generated between the clutch sleeve 611 and the central shaft 622. When the drone rotates, the clutch sleeve 611 rotates accordingly. At a certain moment of rotation, based on the elastic force of the clutch spring 612, the clutch sleeve 611 will suddenly be sleeved on one end of the central shaft 622 to achieve connection.

[0071] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
