Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire extinguishing device technology, specifically a fire extinguishing robot for fire fighting. Background Technology
[0002] When a fire breaks out in a high-rise building, drones equipped with fire extinguishing devices can extinguish the fire at the source on higher floors. However, drones cannot accurately pinpoint the fire source, and the landing location of the extinguishing materials launched by the devices is easily off-target, resulting in poor fire extinguishing effectiveness for firefighting drones.
[0003] A patent search revealed a document titled "Unmanned Aerial Vehicle Firefighting Device and System" (CN215025561U). While this device addresses the aforementioned problems, it adjusts the fire extinguisher's firing angle vertically using a first and second active telescopic rod. However, due to the fire environment, firefighters must repeatedly operate the first and second active telescopic rods to continuously control the spray angle, a time-consuming and labor-intensive process that increases the difficulty of their work and reduces firefighting efficiency. Therefore, this invention designs a firefighting robot to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide a fire-fighting robot for fire protection, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting robot, including a drone, with a mounting column fixed at the bottom center of the drone. The mounting column is made of hollow material. A wireless receiving module is fixed at the top of the drone and connected to the drone via a wire. Rotating rods are connected to the lower left and right sides of the mounting column. A clearance hole is integrally provided inside the rotating rod and communicates with the interior of the mounting column. An installation tube is fixed at the lower rear end of the mounting column. A drainage assembly is provided outside the rotating rod. The drainage assembly includes a connecting rod fixed at the front end of the rotating rod. The connecting rod has an arc-shaped design and is made of hollow material. Connecting heads are fixed on the left and right sides inside the connecting rod. The connecting heads are fixedly inserted through the rotating rod and communicate with the interior of the connecting rod and the clearance hole. A number of spray heads are fixed at the front end of the connecting rod.
[0006] Furthermore, the axes of the two rotating rods are designed to be coaxial, the distance between the two rotating rods is three centimeters, and a partition is fixedly provided at the lower end of the mounting column.
[0007] Furthermore, a placement rod is fixedly provided at the upper end of the mounting column, and placement plates are fixedly provided on the left and right sides of the upper end of the placement rod. A pivot pin is connected to the end of the placement plate away from the placement rod.
[0008] Furthermore, a connecting plate is fixedly provided at the top of the rotating rod away from the mounting post, and a guide hole is integrally provided inside the connecting plate.
[0009] Furthermore, the guide hole is a through hole design, the guide hole has a rectangular cross-section when viewed from the side, and the guide hole is fitted onto the outside of the pivot pin.
[0010] Furthermore, a mounting plate is fixedly mounted on the left side of the outer rear end of the mounting column, a motor is fixedly mounted on the left side of the outer front end of the mounting plate, a worm gear is fixedly mounted on the front end of the motor, and the motor is connected to the wireless receiving module via a wire.
[0011] Furthermore, a worm gear is fixedly sleeved on the outer left side of the placement rod. The worm gear and the worm are designed to mesh with each other, and the worm and the worm gear are misaligned with the mounting column.
[0012] Furthermore, a limiting plate is fixedly provided at the outer front end of the mounting column. The limiting plate is parallel to the mounting plate and is rotatably sleeved on the outside of the worm gear. A counterweight is fixedly provided on the right side of the outer rear end of the limiting plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the arc-shaped design of the connecting rod, can make the liquid sprayed from inside the connecting rod into a fan shape, thereby expanding the range of the liquid sprayed out. Therefore, by using the device in this application, firefighters only need to point the connecting rod toward the designated point of fire extinguishing to quickly extinguish the fire in the fire area, which not only reduces the difficulty of the work of firefighters, but also improves the fire extinguishing efficiency of the fire area.
[0015] 2. Through the mechanical linkage design, this utility model only requires firefighters to turn on the motor, which will cause the motor-linked spray head to swing back and forth around the axis of the rotating rod. Thus, by using the device in this application, the range of liquid spraying is further expanded, thereby improving the fire extinguishing effect in the fire area. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a fire-fighting robot includes a drone 1. A mounting column 2 is fixed at the bottom center of the drone 1. The mounting column 2 is made of hollow material. A wireless receiving module 3 is fixed at the top of the drone 1. The wireless receiving module 3 is connected to the drone 1 via a wire. Rotating rods 4 are connected to the lower left and right sides inside the mounting column 2. A clearance hole 5 is integrally provided inside the rotating rod 4. The clearance hole 5 is connected to the inside of the mounting column 2. An installation pipe 6 is fixed at the lower rear end inside the mounting column 2. A drainage assembly 7 is provided outside the rotating rod 4. The drainage assembly 7 includes a connecting rod 701 fixed at the front end of the rotating rod 4. The connecting rod 701 has an arc-shaped design and is made of hollow material. Connecting heads 702 are fixed on the left and right sides inside the connecting rod 701. The connecting heads 702 are fixed through the rotating rod 4 and are connected to the inside of the connecting rod 701 and the clearance hole 5. A number of spray heads 703 are fixed at the front end inside the connecting rod 701.
[0025] Firefighters first connect the controller of the drone 1 to the wireless receiver module 3 via wireless connection. Then, they connect the fire truck's fire pipe to the installation pipe 6. Using the controller, they fly the drone 1 to the fire area, so that the connecting rod 701 faces the fire area. Then, they turn on the high-pressure water pump on the fire truck. At this time, the liquid flows from the installation pipe 6 through the installation column 2, through the clearance hole 5, and then through the connector 702 into the connecting rod 701. The liquid in the connecting rod 701 is then sprayed to the fire area by the spray head 703. The arc-shaped design of the connecting rod 701 makes the sprayed liquid form a fan shape, thereby expanding the fire extinguishing range of the liquid. Example 2
[0026] like Figure 1 , Figure 2 , Figure 4As shown, the axes of the two rotating rods 4 are designed to be coaxial, and the distance between the two rotating rods 4 is three centimeters. A partition plate 8 is fixed to the lower end of the mounting post 2, and a placement rod 9 is fixed to the upper end of the mounting post 2. Placement plates 10 are fixed to the left and right sides of the upper end of the placement rod 9. A pivot pin 11 is connected to the end of the placement plate 10 away from the placement rod 9. A connecting plate 12 is fixed to the top of the rotating rod 4 away from the mounting post 2. A guide hole 13 is integrally provided inside the connecting plate 12. The guide hole 13 is a through hole design, and the cross-section of the guide hole 13 in side view is rectangular. The guide hole 13 is fitted onto the outside of the pivot pin 11. A mounting plate 14 is fixedly mounted on the left side of the rear end of the mounting column 2. A motor 15 is fixedly mounted on the left side of the front end of the mounting plate 14. A worm gear 16 is fixedly mounted on the front end of the motor 15. The motor 15 is connected to the wireless receiving module 3 through a wire. A worm wheel 17 is fixedly sleeved on the left side of the placement rod 9. The worm wheel 17 and the worm gear 16 are designed to mesh with each other. The worm gear 16 and the worm wheel 17 are offset from the mounting column 2. A limiting plate 18 is fixedly mounted on the front end of the mounting column 2. The limiting plate 18 is parallel to the mounting plate 14. The limiting plate 18 is rotatably sleeved on the outside of the worm gear 16. A counterweight 19 is fixedly mounted on the right side of the rear end of the limiting plate 18.
[0027] According to the operation method in Embodiment 1, firefighters can turn on motor 15. Motor 15 drives worm gear 16 to drive worm wheel 17 to rotate, which in turn rotates placement rod 9, placement plate 10, and pivot pin 11. At this time, pivot pin 11 pushes guide hole 13 to rotate connecting plate 12, rotating rod 4, connecting rod 701, and spray head 703 in a reciprocating up-and-down swinging motion. The purpose is to further expand the range after liquid spraying, thereby improving the fire extinguishing effect in the fire area. Baffle 8 can prevent liquid from contacting placement rod 9, ensuring the stability of placement rod 9 during rotation. The weight of counterweight 19 is equal to the total weight of motor 15, worm gear 16, and worm wheel 17. The design of counterweight 19 ensures the stability of UAV 1 during flight.
