[0002] With the advancement of science and technology, drones are being used more and more widely in various fields, especially in the field of firefighting. Drone fire-fighting systems have the advantages of high efficiency, flexibility, and rapid response, and can quickly reach the scene of a fire to carry out firefighting operations. However, existing drone fire-fighting bomb dispensers still have some problems in actual use. During the operation of the drone, due to external forces such as vibration and wind, the connection between the suction cup and the drone is prone to loosening, causing the suction cup to swing during the movement of the drone. This instability not only affects the fixing effect of the fire-fighting bomb, but may also cause the fire-fighting bomb to fall, posing a serious safety hazard. For this reason, we propose a drone fire-fighting bomb dispenser. Utility Model Content

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0027] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] See also Figures 1-12The utility model provides an embodiment of a UAV fire extinguishing bomb dispenser, comprising a UAV body 100, and a bracket 200 installed at the bottom of the UAV body 100, the bracket 200 is provided with a negative pressure device, at least one sleeve 201 is installed on the bracket 200, a tube body 204 is provided through the sleeve 201, the upper end of the tube body 204 is connected to the negative pressure device, the lower end of the tube body 204 is connected to a suction cup 205, the fire extinguishing bomb body 300 is fixed by the suction cup 205, the upper and lower ends of the sleeve 201 are respectively connected to a support plate assembly, a thread 2041 is provided on the tube body 204, two nuts 207 and a check part are connected to the tube body 204, a thread 2041 is provided on the tube body 204, the nut 207 is connected to the tube body 204 through the thread 2041, the check part is connected between the nut 207 and the support plate assembly, the nut 207 and the check part are connected to form an integral structure and rotate synchronously, and the check part can only rotate counterclockwise after contacting the support plate assembly.

[0029] By adopting such a solution, suction is generated by a negative pressure device to adsorb fire extinguishing bombs or other fire extinguishing materials on the suction cup 205. When the UAV flies near the fire source, the operator can release the suction of the suction cup 205 by controlling the control system on the UAV body 100, thereby releasing the fire extinguishing bomb. By arranging support plate assemblies at both ends of the sleeve 201 and arranging a check portion between the nut 207 and the support plate assembly, as the nut 207 is tightened, the check portion is pushed closer to the support plate assembly. The check portion and the nut 207 cannot rotate relative to each other, and the check portion and the support plate assembly can only rotate in one direction. Therefore, as the nut 207 is continuously pressed, the check portion can prevent the tube body 204 from loosening.

[0030] In one embodiment, the support plate assembly includes an upper support plate 202 installed at the upper end of the sleeve 201 and a lower support plate 203 installed at the lower end of the sleeve 201. The check portion includes a first check plate 208 and a second check plate 210. The first check plate 208 and the second check plate 210 both have a through hole with a diameter larger than the tube body 204. The first check plate 208 is located above the upper support plate 202, and the second check plate 210 is located below the lower support plate 203. The upper support plate 202 and the lower support plate 203 are provided with The check groove 211, the first check plate 208 and the second check plate 210 are provided with a contact piece; wherein, the check groove 211 includes an inward concave portion forming a vertical surface and an inclined surface, the lower end of the inclined surface is connected to the bottom of the vertical surface, and the upper end of the inclined surface transitions to the surface of the upper support plate 202 and the lower support plate 203; the contact piece includes a check surface 216 and a driving surface 215, and locking is achieved when the check surface 216 contacts the vertical surface, and when the driving surface 215 contacts the inclined surface, the driving contact piece forms a retreat space.

[0031] With such a solution, when the check surface 216 is in close contact with the vertical surface in the check groove 211, a locking effect can be achieved. As the nut 207 drives the first check plate 208 and the second check plate 210 to continue to rotate, the driving surface 215 contacts the inclined surface to drive the entire contact piece to contract. When entering the next check groove 211, the contact piece rebounds to achieve re-limitation.

[0032] In one embodiment, the contact piece includes an elastic sheet 213, and the first check plate 208 and the second check plate 210 are both provided with a mounting groove 212. One end of the elastic sheet 213 is connected to the inner side of the mounting groove 212, and the lower end of the elastic sheet 213 is connected to a pull plate 214. In a natural state, the elastic sheet 213 is tilted downward, and the pull plate 214 is in a vertical state. The bottom surface of the elastic sheet 213 forms a driving surface 215, and the side of the pull plate 214 away from the elastic sheet 213 forms a check surface 216. At least one limiting protrusion 2081 is connected to the first check plate 208 and the second check plate 210, and the inner side of the limiting protrusion 2081 is provided with a groove 2082 with the same shape as the outer side of the nut 207.

[0033] With such a solution, a mounting groove 212 is provided on the first check plate 208 and the second check plate 210 for accommodating one end of the elastic sheet 213. One end of the elastic sheet 213 is fixed on the inner side of the mounting groove 212, and the other end is freely suspended and connected to the pull plate 214. When there is no external force, the elastic sheet 213 tilts downward due to its own elasticity, so that the pull plate 214 is in a vertical state. As the nut 207 drives the first check plate 208 and the second check plate 210 to rotate, if the check surface 216 is in close contact with the vertical surface in the check groove 211, a locking effect is achieved, and the driving surface 215 is in contact with the inclined surface. Due to the guiding effect of the inclined surface, the elastic sheet 213 and the pull plate 214 shrink and have retreat space.

[0034] Optionally, an air hole a2042 is provided in the tube body 204, an air hole b2051 is provided in the middle of the suction cup 205, the air hole b2051 is communicated with the air hole a2042, and the output end of the negative pressure device is connected to the air hole a2042.

[0035] Optionally, the number of sleeves 201 is three and they are equidistantly distributed on the bracket 200, and the negative pressure device includes a vacuum pump 400 mounted on the bracket 200 and a catheter assembly 206 connected to the upper end of each tube body 204, and the end of the catheter assembly 206 away from the tube body 204 is connected to the vacuum pump 400.

[0036] Optionally, a parachute assembly 101 is provided on the top of the drone body 100 .

[0037] The present invention uses the suction force generated by the negative pressure device to firmly attach the fire extinguishing bomb or other fire extinguishing material to the suction cup 205. When the drone flies near the fire source, the operator can release the suction force of the suction cup 205 through the control system to quickly release the fire extinguishing bomb. By providing a support plate assembly on the sleeve 201 and a check portion between the nut 207 and the support plate assembly, the structural stability of the entire device is enhanced, preventing the nut 207 from loosening due to external forces such as vibration during the operation of the drone, ensuring the safe transportation and delivery of the fire extinguishing bomb.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
