Description

Technical Field

[0001] This utility model relates to the field of drone accessory equipment technology, and in particular to a drone four-shot fire extinguishing bomb thrower. Background Technology

[0002] Existing drone fire extinguishing bomb throwing devices include two types: one that can only throw spherical fire extinguishing bombs, using a cavity to hold multiple spherical fire extinguishing bombs; after the drone reaches the target location, it opens the cavity door, and the spherical fire extinguishing bombs fall freely; and another type that can throw cylindrical fire extinguishing bombs, using a clamp to hold and fix the fire extinguishing bomb; after the drone reaches the target location, it controls the clamp to open and release the fire extinguishing bomb.

[0003] However, the first approach cannot precisely control the number of fire extinguishing bombs deployed. Furthermore, spherical fire extinguishing bombs are typically designed for direct throwing and lack the safety devices such as the safety pin found on bottled fire extinguishing bombs. During storage, transportation, or in non-emergency situations, spherical fire extinguishing bombs may be prematurely triggered due to accidental contact, high temperatures, or other unforeseen factors, posing a safety hazard.

[0004] The second option involves a complex clamp structure, requiring control to open the clamp, resulting in a complex transmission mechanism and high cost. Furthermore, this type of cylindrical fire extinguishing bomb, launched by a drone, lacks a safety pin, posing a safety hazard. Utility Model Content

[0005] Based on the above analysis, the present invention aims to provide a drone four-shot fire extinguishing grenade thrower to solve the problem that existing drone fire extinguishing grenade throwers cannot simultaneously release the safety pin.

[0006] On one hand, this utility model provides a four-fire extinguishing grenade launcher for unmanned aerial vehicles (UAVs), including a transfer platform, a first loading module, a second loading module, and fire extinguishing grenades; wherein, the transfer platform is fixedly connected to the UAV, and each of the two first loading modules and the two second loading modules carries one fire extinguishing grenade and is fixedly connected to the transfer platform respectively; both the first loading module and the second loading module include a driving element, which can drive a connecting rod to rotate to pull out the safety pin of the fire extinguishing grenade, thereby causing the fire extinguishing grenade to be released in free fall and simultaneously activated.

[0007] Furthermore, the first loading module includes a first support plate and a first loading unit. The first support plate has two parts, which are respectively fixed on both sides of the first loading unit. The second loading module includes a second support plate and a second loading unit. The second support plate has two parts, which are respectively fixed on both sides of the second loading unit, and the length of the second support plate is greater than the length of the first support plate.

[0008] Furthermore, the top end of the first support plate is provided with a first threaded hole for fixed connection with the adapter platform.

[0009] Furthermore, the first loading unit includes a mounting base, a drive element, and a connecting rod.

[0010] Furthermore, the driving element is fixedly mounted on the mounting base, one end of the connecting rod is located at the output end of the driving element, and the other end of the connecting rod is connected to the safety pin of the fire extinguishing bomb.

[0011] Furthermore, the driving element is a servo motor.

[0012] Furthermore, the mounting base is a block-shaped body, and the cross-section of the mounting base is hook-shaped, including a rectangular portion and an arc-shaped portion protruding from one side of the rectangular portion.

[0013] Furthermore, the rectangular portion of the mounting base is provided with a first mounting groove, which is used to fix the driving element.

[0014] Furthermore, the arc-shaped portion of the mounting base is provided with a second mounting groove, the cross-section of the second mounting groove is circular, and the diameter of the top of the second mounting groove is smaller than the diameter of its bottom.

[0015] Furthermore, the arcuate portion of the mounting base also includes openings, each of which faces outwards.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] (1) This utility model can drive the connecting rod to rotate through the driving element to remove the safety pin of the fire extinguishing bomb, so that the fire extinguishing bomb is activated while falling freely.

Detailed Implementation

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0033] Example 1

[0034] A specific embodiment of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, a four-fire extinguishing grenade launcher for unmanned aerial vehicles (UAVs) is disclosed, comprising a transfer platform 1, a first loading module 2, a second loading module 3, and fire extinguishing grenades 4. The transfer platform 1 is fixedly connected to the UAV. Each of the two first loading modules 2 and the two second loading modules 3 carries one fire extinguishing grenade 4 and is fixedly connected to the transfer platform 1. Both the first loading module 2 and the second loading module 3 include a driving element that drives a linkage to rotate, thereby disengaging the safety pin 41 of the fire extinguishing grenade 4, causing the fire extinguishing grenade 4 to be launched during free fall.

[0035] The adapter platform 1 is a flat plate structure. Its upper surface can be fixedly connected to the UAV, and its lower surface has four mounting positions arranged in a grid pattern. Each mounting position can install one first loading module 2 or one second loading module 3. In this embodiment, the two first loading modules 2 are located on the left side, and the two second loading modules 3 are located on the right side.

[0036] The structure of the first loading module 2 is as follows: Figures 4-7 As shown.

[0037] See Figure 4 The first loading module 2 includes a first support plate 21 and a first loading unit 22. The first support plate 21 consists of two parts, fixedly disposed on both sides of the first loading unit 22. A first threaded hole 211 is provided at the top of the first support plate 21, through which the first loading module 2 is fixedly connected to the transfer platform 1.

[0038] The first loading unit 22 includes a mounting base 221, a drive element 222, and a connecting rod 223. The mounting base 221 is used to mount the drive element 222 and the fire extinguishing bomb 4.

[0039] The drive element 222 is fixedly mounted on the mounting base 221. One end of the connecting rod 223 is located at the output end of the drive element 222, and the other end is connected to the safety pin 41 of the fire extinguishing bomb 4. It can be driven by the drive element 222 to rotate and pull out the safety pin 41 of the fire extinguishing bomb 4. The drive element 222 is preferably a servo motor, but it can also be other similar power elements.

[0040] See Figure 3 and Figure 7The mounting base 221 is a block-shaped body with a hook-shaped cross-section, including a rectangular portion and an arc-shaped portion protruding from one side of the rectangular portion. The outer diameter of the arc-shaped portion is equal to the length of the long side of the rectangular portion. One first support plate 21 is located outside the rectangular portion, and another first support plate 21 is located outside the arc-shaped cylindrical portion.

[0041] See Figure 5 , Figure 6 and Figure 7 The rectangular portion of the mounting base 221 is provided with a first mounting groove 2211, which is a rectangular groove that extends through the upper and lower surfaces of the rectangular portion. This first mounting groove 2211 is used to fix and mount the drive element 222. Two second threaded holes 2212 are respectively provided on the outer side of the wider side of the first mounting groove 2211 to assist in fixing the drive element 222. A first slot 2213 is provided on the outer longer sidewall of the first mounting groove 2211 for accommodating the power and signal lines of the drive element 222.

[0042] The arc-shaped portion of the mounting base 221 is provided with a second mounting groove 2214. The second mounting groove 2214 penetrates the upper and lower surfaces of the arc-shaped portion. The cross-section of the second mounting groove 2214 is circular, and the diameter of the top of the second mounting groove 2214 is smaller than the diameter of its bottom. That is, the second mounting groove 2214 is a groove that is narrow at the top and wide at the bottom, with a smooth transition in the middle. This design makes the second mounting groove 2214 suitable for mounting the fire extinguishing bomb 4.

[0043] A second slot 2215 is provided on the side of the second mounting slot 2214 adjacent to the first mounting slot 2211. The second slot 2215 is a semi-circular arc-shaped slot protruding towards the first mounting slot 2211. It is used to provide space for the safety pin 41 of the fire extinguishing bomb 4, so that the safety pin 41 is suspended after the fire extinguishing bomb 4 is placed in the second mounting slot 2214, avoiding interference between the safety pin 41 and the upper surface of the mounting base 221, or making it difficult to pull out due to friction.

[0044] The arc-shaped portion of the mounting base 221 also includes an opening 2216 that extends through the upper and lower surfaces of the arc-shaped portion, with rounded corners at the top on both sides of the opening. The opening 2216 facilitates the deployment of the fire extinguishing grenade 4, preventing jamming, and also allows the safety pin 41 to fall freely in the direction it is pulled out. See also Figure 3 The openings 2216 of the first loading module 2 and the second loading module 3 both face outwards so that the delivery of the fire extinguishing bombs 4 does not affect each other.

[0045] The structure of the second loading module 3 is as follows: Figure 8As shown, it includes a second support plate 31 and a second loading unit 32. The second support plate 31 is longer than the first support plate 21 to avoid interference with other equipment of the UAV. The structure of the second loading unit 32 is exactly the same as that of the first loading unit 22, and will not be described again here.

[0046] The structure of fire extinguishing bomb 4 is as follows Figure 9 As shown, it includes a cylinder body, a cylinder cover, a retaining ring, and a safety pin 41. The cylinder body and cylinder cover are fixedly connected as a single unit. Multiple retaining pins are evenly distributed on the outer circumference of the retaining ring, which can engage with the top of the second mounting groove 2214. The retaining ring also has a through hole through which the safety pin 41 passes and inserts into the cylinder cover, fixing the retaining ring to the cylinder cover. After the safety pin 41 is pulled out, the cylinder cover can be disengaged from the retaining ring, and the fire extinguishing bomb 4 is activated and enters the working state.

[0047] During operation, four fire extinguishing bombs 4 are loaded into the first loading module 2 and the second loading module 3 respectively. After the UAV flies to the target position, the controller controls one or more of the drive elements 222 to rotate, driving the connecting rod 223 to rotate, thereby pulling out the safety pin 41 of the corresponding fire extinguishing bomb 4. Then the fire extinguishing bomb 4 falls freely and is simultaneously activated to enter the working state. After landing, it can explode to extinguish the fire.

[0048] Compared with existing technologies, the UAV four-fire extinguishing grenade launcher provided in this embodiment can drive the linkage to rotate via a drive element to remove the safety pin of the fire extinguishing grenade, thereby causing the fire extinguishing grenade to be released during free fall. It achieves two functions in one action, with a simple structure and convenient operation. It can also deliver one to four fire extinguishing grenadees at a time, allowing for selection of the delivery location and quantity based on actual conditions, making fire suppression more targeted.

[0049] 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 changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
