Description

Technical Field

[0001] This utility model relates to the field of fire-fighting drone technology, and in particular to a fire-fighting drone that can change the spray angle of a water spray pipe. Background Technology

[0002] Firefighting drones are emergency rescue equipment that integrates modern aviation technology, the Internet of Things, and artificial intelligence. By operating from the air, they overcome terrain limitations and significantly improve the efficiency and safety of fire fighting and disaster response.

[0003] A utility model patent with patent authorization announcement number CN221418624U discloses a fire-fighting drone, including a drone body, a water supply pipe, a charging cable, and a partition component. The water supply pipe is fixed to the bottom of the drone body, one end of which moves with the drone body, and the other end extends to the ground and connects to a water supply device. One end of the charging cable is electrically connected to the drone body, and the other end extends to the ground and connects to a power source. The partition component includes a first connector, a second connector, and a top abutment. The first connector is detachably installed on the water supply pipe, the second connector is detachably installed on the charging cable, and the top abutment is connected to both the first and second connectors. The top abutment is used to restrict the first connector from moving away from or towards the second connector.

[0004] However, existing fire-fighting drones also have certain shortcomings. Most existing fire-fighting drones use a fixed installation method to connect the water spray pipe to the drone components, which restricts the spray angle of the water spray pipe, resulting in poor spray range and efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fire-fighting drone that can change the spray angle of a water hose.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fire-fighting drone capable of changing the spray angle of a water hose includes a drone body. Two evenly distributed landing gears are fixedly mounted on the lower end of the drone body. Four evenly distributed drone rotors are arranged on the surface of the drone body. A servo motor is fixedly mounted on the lower end of the drone body. A small gear is fixedly sleeved on the outer side of the output shaft of the servo motor. A support shaft contacts the lower end of the drone body. A large gear is fixedly sleeved on the outer side of the support shaft, meshing with the small gear. A rotating disk is fixedly sleeved on the outer side of the support shaft. A limit block is fixedly connected to the lower end of the drone body, and the limit block is slidably connected to the rotating disk. A water hose body is fixedly mounted on the lower end of the support shaft. A delivery hose is provided on the lower side of the water hose body. A lubrication mechanism is provided at the lower end of the drone body.

[0008] In addition, a preferred structure is that four limiting blocks are provided, and the four limiting blocks are arranged in a circular array on the rotating disk. By setting the limiting blocks, the rotating disk can be limited and supported to ensure the rotational stability of the support shaft.

[0009] In addition, a preferred structure is that a limiting post is fixedly connected to the lower end of the drone body, and a baffle is fixedly connected to the right side of the output shaft of the servo motor. Through the cooperation of the limiting post and the baffle, the deflection angle of the output shaft of the servo motor can be limited, avoiding problems such as accidental impact of the water spray pipe body.

[0010] Furthermore, in a preferred configuration, the lubrication mechanism includes an oil reservoir. The lower end of the UAV body is fixedly connected to the oil reservoir, and a sealing column is slidably connected to the inner wall of the oil reservoir. A connecting rod is fixedly connected to the upper end of the sealing column, and a magnetic block is fixedly connected to the upper end of the connecting rod. The magnetic block is slidably connected to the oil reservoir, and a spring is provided on the outer side of the connecting rod. An electromagnet is fixedly installed on the inner wall of the oil reservoir. Through the combined use of the electromagnet, magnetic block, and other structures, the sealing column can be disengaged from the flow hole of the oil reservoir, thereby allowing the lubricating oil to flow and drip for use.

[0011] In addition, a preferred structure is that the sealing post is located directly above the meshing point of the large gear and the small gear, and the sealing post is made of rubber. By setting the sealing post, the oil reservoir can be sealed.

[0012] In addition, a preferred structure is that one end of the spring is welded to the oil reservoir, and the other end of the spring is fixedly connected to the magnetic block. The magnetic block can be connected and used by means of the spring.

[0013] In addition, a preferred structure is that the electromagnet is located directly above the magnetic block, and the electromagnet is fixedly connected to the oil reservoir through two symmetrically distributed support plates. By setting the electromagnet, the magnetic block can be magnetically attracted.

[0014] The beneficial effects of this utility model are as follows: by setting up a delivery hose, water can be input into the spray pipe. Under the action of the spray pipe, the water can be sprayed at high pressure. Under the action of servo motor, large gear and other structures, the support shaft can drive the spray pipe to rotate, thereby adaptively adjusting the spray angle of the spray pipe. With the cooperation of rotating disk, limit block and other structures, the rotational stability of the support shaft and other components can be ensured. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4A fire-fighting drone that can change the spray angle of a water hose includes a drone body 1. Two evenly distributed landing gears 2 are fixedly installed at the lower end of the drone body 1. Four evenly distributed drone rotors 3 are provided on the surface of the drone body 1. A servo motor 4 is fixedly installed at the lower end of the drone body 1. A small gear 5 is fixedly sleeved on the outside of the output shaft of the servo motor 4. A support shaft 6 is in contact with the lower end of the drone body 1. A large gear 7 is fixedly sleeved on the outside of the support shaft 6. The large gear 7 meshes with the small gear 5. A rotating disk 8 is fixedly sleeved on the outside of the support shaft 6. A limit block 9 is fixedly connected to the lower end of the drone body 1. The limit block 9 is slidably connected to the rotating disk 8. A water hose body 10 is fixedly installed at the lower end of the support shaft 6. A delivery hose 11 is provided on the lower side of the water hose body 10.

[0022] Reference Figure 1 , Figure 2 , Figure 3 There are four limit blocks 9, which are arranged in a circular array on the rotating disk 8. By setting the limit blocks 9, the rotating disk 8 can be limited and supported to ensure the rotation stability of the support shaft 6. The lower end of the UAV body 1 is fixedly connected to the limit post 12, and the right side of the output shaft of the servo motor 4 is fixedly connected to the baffle 13. By using the limit post 12 and the baffle 13 together, the deflection angle of the output shaft of the servo motor 4 can be limited to avoid accidental impacts to the water spray pipe body 10.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The lower end of the drone body 1 is provided with a lubrication mechanism 14, which includes an oil reservoir 140. The oil reservoir 140 is fixedly connected to the lower end of the drone body 1. A sealing column 141 is slidably connected to the inner wall of the oil reservoir 140. A connecting rod 142 is fixedly connected to the upper end of the sealing column 141. A magnetic block 143 is fixedly connected to the upper end of the connecting rod 142. The magnetic block 143 is slidably connected to the oil reservoir 140. A spring 144 is provided on the outer side of the connecting rod 142. An electromagnet 145 is fixedly installed on the inner wall of the oil reservoir 140. Through the cooperation of the electromagnet 145, the magnetic block 143 and other structures, the sealing column 141 can be disengaged from the flow hole of the oil reservoir 140, so that the lubricating oil can flow and drip for use.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The sealing post 141 is located directly above the meshing point of the large gear 7 and the small gear 5. The sealing post 141 is made of rubber. By setting the sealing post 141, the oil reservoir 140 can be sealed. One end of the spring 144 is welded to the oil reservoir 140, and the other end of the spring 144 is fixedly connected to the magnetic block 143. By setting the spring 144, the magnetic block 143 can be connected. The electromagnet 145 is located directly above the magnetic block 143. The electromagnet 145 is fixedly connected to the oil reservoir 140 through two symmetrically distributed support plates. By setting the electromagnet 145, the magnetic block 143 can be magnetically attracted.

[0025] The specific implementation process of this utility model is as follows: In use, through the setting of the delivery hose 11, water can be continuously delivered to the drone body 1 flying into the air via the water spray pipe body 10. Under the action of the water spray pipe body 10, the water can be sprayed at high pressure to achieve the effect of fire extinguishing and fire fighting. When the servo motor 4 drives the output shaft to rotate, it can drive the pinion 5 to rotate. Under the meshing relationship, the pinion 5 can drive the large gear 7 to rotate, thereby driving the support shaft 6 to rotate and driving the water spray pipe body 10 to rotate, adjusting the angle of the water spray pipe body 10. When the support shaft 6 rotates, it can drive the rotating disk 8 to rotate along the inner wall of the limiting block 9, thereby limiting and supporting the rotation of the support shaft 6, so as to ensure the rotational stability of the support shaft 6 and other components.

[0026] When the electromagnet 145 is powered on, a strong magnetic force is generated, which magnetically attracts the magnetic block 143, pulling the connecting rod 142 to move. This causes the spring 144 to deform and move the sealing column 141, causing the sealing column 141 to disengage from the flow hole of the oil reservoir 140. This allows the lubricating oil to flow and drip, ultimately bringing the lubricating oil into contact with the large gear 7 and the small gear 5, lubricating them and reducing hard wear between them, thus ensuring good transmission performance.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
