Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and in particular to a gimbal mounted on an unmanned helicopter for firefighting. Background Technology

[0002] As firefighting operations become increasingly complex, helicopters are needed to extinguish fires in scenarios such as high-rise residential fires, chemical industrial park leaks and fires, and forest fire detection. Traditional helicopters often lack dedicated buffer structures, and the vibrations during helicopter flight are directly transmitted to the firefighting equipment. Furthermore, the angle of the firefighting equipment cannot be adjusted, requiring the helicopter to adjust its flight angle to match the firefighting requirements, which places high demands on the operator. Utility Model Content

[0003] The purpose of this invention is to provide a gimbal for firefighting unmanned helicopters to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A gimbal for firefighting unmanned helicopters includes a base and a suspension bracket fixedly installed at the bottom of the helicopter body. The suspension bracket is fixedly installed at the bottom of the base, and an adjustment module is fixedly installed at the bottom of the suspension bracket. The adjustment module is used to adjust the angle and support firefighting equipment.

[0005] By adopting the above technical solution, fire-fighting equipment can be stably mounted under the helicopter. The rigid connection between the base and the suspension bracket prevents the mounted components from loosening and falling off during flight. Furthermore, the angle adjustment function of the adjustment module solves the problem of the changing location of fire sources and the complexity of obstacles at the fire scene.

[0006] In a further embodiment, the base includes an upper top plate, support columns, and a lower bottom plate. The upper top plate is fixedly installed on the bottom of the helicopter body. Multiple support columns are provided, and multiple support columns are fixedly installed on the bottom of the upper top plate. The same lower bottom plate is fixedly installed on the bottom of each support column.

[0007] By adopting the above technical solutions, the upper plate is fitted and fixed to the bottom of the helicopter, ensuring that the base is installed firmly as a whole; the design of multiple support columns can distribute the weight of the mounted components and avoid deformation of the base due to single-point stress.

[0008] In a further embodiment, the suspension bracket includes buffer columns, load-bearing columns, and a first connecting plate. The buffer columns are fixedly installed at the four corners of the top of the bottom plate. The first connecting plate is fixedly installed on the top of the buffer column. Multiple load-bearing columns are fixedly installed on the bottom of the first connecting plate. The same second connecting plate is fixedly installed on the bottom of the load-bearing columns.

[0009] By adopting the above technical solution, the buffer column can absorb the vibration during helicopter flight and prevent the vibration from being transmitted to the adjustment module and fire-fighting equipment below.

[0010] In a further embodiment, the adjustment module includes a first servo, a second servo, a first connecting rod, a second connecting rod, a first mounting bracket, a second mounting bracket, and a third mounting bracket. The first mounting bracket is fixedly mounted on the bottom of the second connecting plate, and the second mounting bracket is rotatably mounted on the bottom of the first mounting bracket. A first receiving groove is provided on the front side of the first mounting bracket. The first servo is fixedly mounted in the first receiving groove of the first mounting bracket. The rotating shaft of the first servo is fixedly mounted to one end of the first connecting rod. One end of the third connecting rod is rotatably mounted to the other end of the first connecting rod. The other end of the third connecting rod is rotatably mounted on the second mounting bracket. The first servo is used to drive the second mounting bracket to rotate around the first mounting bracket. The third mounting bracket is rotatably mounted on the front end of the second mounting bracket. A second receiving groove extending through the left and right sides is provided on the left side of the second mounting bracket. The second servo is fixedly mounted in the second receiving groove. The rotating shaft of the second servo is fixedly mounted to one end of the second connecting rod. One end of the fourth connecting rod is rotatably mounted to the other end of the second connecting rod. The other end of the fourth connecting rod is rotatably mounted on the third mounting bracket. The second servo is used to drive the third mounting bracket to rotate around the second mounting bracket.

[0011] By adopting the above technical solution, the first servo motor drives the second mounting bracket to rotate around the first mounting bracket, thereby controlling the angle of the fire-fighting equipment; the second servo motor drives the third mounting bracket to rotate around the second mounting bracket, thereby achieving rotation; and compared with direct rigid connection, the linkage transmission can reduce the impact force when the servo motor starts, while increasing the load-bearing capacity.

[0012] In a further embodiment, the second mounting bracket is U-shaped, and the third mounting bracket is located between the U-shapes of the second mounting bracket.

[0013] By adopting the above technical solution, the mounting points on both sides of the U-shape can make the third mounting bracket rotate more smoothly, avoiding swaying caused by force on one side.

[0014] In a further embodiment, the second connecting plate is located at the bottom of the lower base plate, and there is a buffer gap between the second connecting plate and the lower base plate.

[0015] In summary, this utility model has the following beneficial effects: 1. The angle of the fire-fighting equipment can be controlled by driving the second mounting bracket to rotate around the first mounting bracket via the first servo motor; the rotation can be achieved by driving the third mounting bracket to rotate around the second mounting bracket via the second servo motor; and compared with a direct rigid connection, the linkage transmission can reduce the impact force when the servo motor is started, while increasing the load-bearing capacity.

The suspension bracket 2 is fixedly installed at the bottom of the base 1, and an adjustment module 3 is fixedly installed at the bottom of the suspension bracket 2. The adjustment module 3 is used to adjust the angle and support firefighting equipment.

[0021] The base 1 includes an upper top plate 11, support columns 12 and a lower bottom plate 13. The upper top plate 11 is fixedly installed at the bottom of the helicopter body. Multiple support columns 12 are provided and fixedly installed at the bottom of the upper top plate 11. The same lower bottom plate 13 is fixedly installed at the bottom of the support columns 12.

[0022] The suspension bracket 2 includes a buffer column 21, a bearing column 22 and a first connecting plate 23. The buffer columns 21 are fixedly installed on the four corners of the top of the bottom plate 13. The first connecting plate 23 is fixedly installed on the top of the buffer column 21. Multiple bearing columns 22 are fixedly installed on the bottom of the first connecting plate 23. The same second connecting plate 4 is fixedly installed on the bottom of the bearing column 22.

[0023] Adjustment module 3 includes a first servo motor 31, a second servo motor 32, a first connecting rod 33, a second connecting rod 34, a first mounting bracket 35, a second mounting bracket 36, and a third mounting bracket 37. The first mounting bracket 35 is fixedly installed at the bottom of the second connecting plate 4, and the second mounting bracket 36 is rotatably installed at the bottom of the first mounting bracket 35. A first receiving groove is provided on the front side of the first mounting bracket 35. The first servo motor 31 is fixedly installed in the first receiving groove of the first mounting bracket 35. The rotating shaft of the first servo motor 31 is fixedly installed at one end of the first connecting rod 33, and one end of the third connecting rod 5 is rotatably installed at the other end of the first connecting rod 33. The first servo motor 31 is used to drive the second mounting frame 36 to rotate around the first mounting frame 35. The front end of the second mounting frame 36 is rotatably mounted with a third mounting frame 37. The left side of the second mounting frame 36 has a second through-hole groove. The second servo motor 32 is fixedly mounted in the second through-hole. The shaft of the second servo motor 32 is fixedly mounted to one end of the second connecting rod 34. The other end of the second connecting rod 34 is rotatably mounted with one end of the fourth connecting rod 6. The other end of the fourth connecting rod 6 is rotatably mounted on the third mounting frame 37. The second servo motor 32 is used to drive the third mounting frame 37 to rotate around the second mounting frame 36.

[0024] The second mounting bracket 36 is U-shaped, the third mounting bracket 37 is located between the U-shapes of the second mounting bracket 36, the second connecting plate 4 is located at the bottom of the lower base plate 13, and there is a buffer gap between the second connecting plate 4 and the lower base plate 13.

[0025] Specific implementation process: First, the fire-fighting equipment is fixed on the third mounting frame 37. During the flight of the helicopter to the fire scene, the top plate 11 of the base 1 is closely attached to the bottom of the fuselage. Multiple support columns 12 evenly transfer the weight of the mounted components to the fuselage to avoid structural deformation caused by single-point force. At the same time, the buffer columns 21 at the four corners of the suspension bracket 2 continuously absorb the vibration of the fuselage to prevent the fire-fighting equipment from deviating from the preset position due to vibration.

[0026] Based on the location of the fire source, the first servo motor 31 is activated. The first servo motor 31 rotates within the receiving slot of the first mounting bracket 35, and through the first connecting rod 33, it drives the third connecting rod 5 to move, causing the second mounting bracket 36 to slowly rotate around the first mounting bracket 35. Then, the second servo motor 32 is activated, and the second servo motor 32 pulls the fourth connecting rod 6 through the second connecting rod 34, causing the third mounting bracket 37 to rotate within the U-shaped gap of the second mounting bracket 36, thereby aiming at the fire source and extinguishing the fire.
