Technical Field
[0001] This utility model relates to the technical field of fire-extinguishing ball throwing devices, specifically a fire-extinguishing ball throwing device for drones. Background Technology
[0002] Drones are unmanned aircraft that use radio remote control equipment and onboard program control devices. In the process of using drones for fire fighting, fire extinguishing devices are usually used to drop fire extinguishing balls so that the fire extinguishing balls explode and automatically spray dry powder to extinguish the fire.
[0003] In existing technologies, when drones drop fire extinguishing balls, the balls are typically mounted on four drop points on the bottom of the drone. After the drone moves to the designated location, the fire extinguishing balls are dropped. However, in actual use, the four drop points are evenly distributed at the four corners of the drone's bottom, resulting in inconsistent landing positions. When all fire extinguishing balls need to be dropped from a single point, the drone's position needs to be recalibrated, causing the fire extinguishing balls to not be dropped in a timely manner. Therefore, an improved drone fire extinguishing ball dropping device is needed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a device for throwing fire extinguishing balls by a drone 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-extinguishing ball throwing device for drones, including a support leg, a fixed-point dropping mechanism at the top of the support leg, and an installation mechanism at the top of the fixed-point dropping mechanism.
[0006] The fixed-point dropping mechanism includes an alternating throwing component and a limiting component, with the limiting component located outside the alternating throwing component.
[0007] Preferably, the alternating throwing assembly includes a fixed shell, which is fixedly installed on the top of the support leg. A throwing tube is fixedly installed inside the fixed shell. A branch tube is fixedly installed on the top of the throwing tube. A placement tube and a motor are fixedly installed on the top of the fixed shell. The fire extinguishing ball body is disposed inside the placement tube. An arc groove plate is fixedly installed on the bottom of the drive shaft of the motor to facilitate the throwing of the fire extinguishing ball body from a single point by the alternating throwing assembly.
[0008] Preferably, the arc groove plate is disposed inside the fixed shell, and the bottom of the arc groove plate is movably installed with the top of the bifurcation pipe to facilitate the alternating throwing of the fire extinguishing ball body.
[0009] Preferably, the limiting component includes a connecting seat, which is fixedly installed on the outside of the placement tube. A double-rod bidirectional threaded rod is rotatably installed inside the connecting seat. Limiting rods are fixedly installed on both the inner and outer sides of the connecting seat. A limiting block is slidably installed on the outside of the limiting rod, so as to limit the fire extinguishing ball body through the limiting component.
[0010] Preferably, the limiting block has a threaded groove inside, and the double-rod bidirectional threaded rod is threaded inside the threaded groove inside the limiting block, which facilitates the movement of the limiting block under normal conditions.
[0011] Preferably, the installation mechanism includes a connecting bracket, which is fixedly installed on the top of the fixed shell. A fixing block one is fixedly installed at the end of the connecting bracket away from the fixed shell. A fixing block two is provided on the top of the fixing block one. Bolts are provided inside the fixing block one and the fixing block two. Nuts are installed on the external threads of the bolts, so as to facilitate the connection and fixation of the device to the drone through the installation mechanism.
[0012] Preferably, holes are provided at the corresponding positions of the fixing block one and fixing block two and the bolt, and the bolt is slidably installed inside the holes provided inside the fixing block one and fixing block two, so as to facilitate fixing the fixing block one and fixing block two.
[0013] Compared with the prior art, this utility model provides a device for throwing fire extinguishing balls by a drone, which has the following beneficial effects:
[0014] 1. The fire extinguishing ball throwing device of this drone, through the set fixed-point falling mechanism, allows the fire extinguishing ball body to be loaded through the set placement tube during use. The transmission of the double-rod bidirectional threaded rod can limit the fire extinguishing ball body to prevent it from falling out of the placement tube. Through the rotation of the arc groove plate, the fire extinguishing ball body can be dropped alternately. When the fire extinguishing ball body falls, it will be thrown out from the inside of the throwing tube in sequence inside the bifurcation tube, so that the fire extinguishing ball body can be fixed at a certain point for throwing. There is no need to calibrate the position of the drone when throwing at a fixed point, ensuring that the fire extinguishing ball body can be thrown in a timely manner as needed.
[0015] 2. The fire-throwing device of the drone, through the set installation mechanism, can be fixed to the drone by covering the first and second fixing blocks on the drone's feet and tightening them with bolts and nuts during use, thus realizing the function of installing and fixing the fire-throwing device to the drone.

[0025] Example 1:
[0026] Please see Figure 1-4 This utility model provides a technical solution: a fire-extinguishing ball throwing device for drones, including a support leg 1, a fixed-point falling mechanism 2 is provided on the top of the support leg 1, and an installation mechanism 3 is provided on the top of the fixed-point falling mechanism 2.
[0027] The fixed-point dropping mechanism 2 includes an alternating throwing component 21 and a limiting component 22, with the limiting component 22 located outside the alternating throwing component 21.
[0028] Furthermore, the alternating throwing assembly 21 includes a fixed shell 211, which is fixedly installed on the top of the support leg 1. A throwing tube 212 is fixedly installed inside the fixed shell 211. A branch tube 213 is fixedly installed on the top of the throwing tube 212. A placement tube 214 and a motor 216 are fixedly installed on the top of the fixed shell 211. The fire extinguishing ball body 215 is provided inside the placement tube 214. An arc groove plate 217 is fixedly installed at the bottom of the drive shaft of the motor 216 to facilitate the throwing of the fire extinguishing ball body 215 from a single point by the alternating throwing assembly 21.
[0029] Furthermore, the arc groove plate 217 is disposed inside the fixed shell 211, and the bottom of the arc groove plate 217 is movably installed with the top of the branch pipe 213, which facilitates the alternating throwing of the fire extinguishing ball body 215.
[0030] Furthermore, the limiting component 22 includes a connecting seat 221, which is fixedly installed on the outside of the placement tube 214. A double-rod bidirectional threaded rod 222 is rotatably installed inside the connecting seat 221. Limiting rods 223 are fixedly installed on both the inner and outer sides of the connecting seat 221. A limiting block 224 is slidably installed on the outside of the limiting rod 223, so as to limit the fire extinguishing ball body 215 through the limiting component 22.
[0031] Furthermore, the limiting block 224 has a threaded groove inside, and the double-rod bidirectional threaded rod 222 is threaded inside the threaded groove inside the limiting block 224, which facilitates the movement of the limiting block 224 under normal conditions.
[0032] Example 2:
[0033] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the installation mechanism 3 includes a connecting bracket 31, which is fixedly installed on the top of the fixed housing 211. A fixing block 32 is fixedly installed at the end of the connecting bracket 31 away from the fixed housing 211. A fixing block 33 is provided on the top of the fixing block 32. Bolts 34 are provided inside the fixing blocks 32 and 33. Nuts 35 are installed on the external threads of the bolts 34, so as to facilitate the connection and fixation of the device to the drone through the installation mechanism 3.
[0034] Furthermore, holes are provided at the corresponding positions of the fixing block 32 and fixing block 33 and the bolt 34, and the bolt 34 is slidably installed inside the holes provided inside the fixing block 32 and fixing block 33, so as to fix the fixing block 32 and fixing block 33.
[0035] In actual operation, when this device is used, the support leg 1 is placed on the ground, and the drone's footplate is placed inside the fixing block 32. The connecting bracket 31 then supports the drone. Next, the fixing block 33 is placed on top of the drone's footplate. The fixing blocks 32 and 33 are then tightened using bolts 34 and nuts 35, completing the installation between the device and the drone. Then, the double-bar bidirectional threaded rod 222 is rotated, causing the limiting block 224 to move out of the placement tube 214 under the restriction of the limiting rod 223. The fire extinguishing ball body 215 is then placed inside the placement tube 214. The double-bar bidirectional threaded rod 222 is rotated to limit the fire extinguishing ball body 215 by the limiting block 224. At this time, the device can be taken to the place where fire needs to be extinguished by a drone for throwing. When a fixed point is needed, the drone does not need to move. The drive motor 216 causes the arc groove plate 217 to rotate. When the arc groove plate 217 and the branch pipe 213 alternately contact, the fire extinguishing ball body 215 will fall alternately. After the fire extinguishing ball body 215 enters the interior of the branch pipe 213, it will roll into the interior of the throwing pipe 212 and be thrown out from the interior of the throwing pipe 212, ensuring that each fire extinguishing ball body 215 is thrown and falls from a single point.
