[0002] Traditional firefighting and rescue mainly rely on fire trucks and firefighters to directly enter the scene and use fire ladders for high-pressure firefighting and rescue. Usually, the firefighting efficiency is low and the firefighters are also in danger of their lives. Especially when there is a high-level fire source, it is even impossible to carry out firefighting and rescue work.

On the same structural member, the side facing the inside of the overall structure of the drone fireproof bomb mounting and delivery device is the inner side, and the side facing the outside of the overall structure of the drone fireproof bomb mounting and delivery device is the outer side.

[0044] Combine the following Figure 1-Figure 9 , more specifically describe the technical solution of the drone fireproof bomb mounting and delivery device of the utility model:

[0045] like Figure 1 , 2 As shown in FIG. 3 , this embodiment shows a UAV fireproof bomb mounting and delivery device, which is used to mount and deliver a fireproof bomb 200. The main body structure of the fireproof bomb 200 of this embodiment is cylindrical, and two fireproof bomb clip ring grooves 201 are arranged axially parallel on the main body structure for fastening when loading the bomb.

[0046] like Figure 2 As shown, the drone landing gear 100 of this embodiment is composed of multiple structural beams, which are specifically steel pipes. The drone fire bomb mounting and delivery device of this embodiment is installed on two upper structural beams 101 arranged parallel to the Y axis and arranged oppositely on the upper part of the drone landing gear 100. This embodiment is preferably capable of simultaneously mounting and delivering two fire bombs 200 arranged side by side along the X axis.

[0047] Specifically, the drone fireproof bomb mounting and delivery device of this embodiment includes a fixing frame assembly 1, two sets of unhooking assemblies 2 and two sets of movable mounting assemblies 3.

[0048] The fixing frame assembly 1 is mounted on two upper structural beams 101 and is detachably connected to the upper structural beams 101; the two unhooking assemblies 2 are hoisted and connected to the middle of the two upper structural beams 101 respectively; and the two ends of the movable mounting assembly 3 are respectively connected to the fixing frame assembly 1 and the unhooking assembly 2.

[0049] like Figure 3 As shown, the fixing frame assembly 1 includes a main beam unit, an axial positioning unit 12 , a fixing hook unit 13 and a fixing frame connecting unit 14 .

[0050] The main beam unit of this embodiment includes two main beams 11 symmetrically arranged at both ends of the upper structural beam 101; the two oppositely arranged main beams 11 are arranged parallel to the X axis and mounted on the two opposite upper structural beams 101. A fixing frame connection unit 14 is connected to each end of the main beam 11; the fixing frame connection unit 14 can be engaged with the upper structural beam 101 arranged in the Y direction on the upper part of the drone landing gear 100, thereby fixing the main beam 11 to the drone landing gear 100. This arrangement allows the spacing between the two main beams 11 to be adjusted.

[0051] Preferably, the main beam 11 is a shell made of a plate, specifically a rectangular shell, which can effectively reduce the weight of the device of the utility model.

[0052] like Figure 5 and Figure 6 As shown, the fixing frame connection unit 14 includes a positioning connection subunit 141 , a fixing frame connection power source 142 and a fixing frame movable clamping plate 143 .

[0053] The positioning connection subunit 141 is limited on the upper structural beam 101 and connected to the main beam 11. The first end of the fixed frame movable clamp 143 is rotatably connected to the positioning connection subunit 141 through the fixed frame connected power source 142, and is fixed to the UAV landing gear through the positioning connection subunit 141, specifically locked on the upper structural beam 101.

[0054] like Figure 6As shown, the positioning and connecting subunit 141 includes two fixing frame mounting plates 1411 and a fixing frame connection positioning body 1412. Specifically in this embodiment, the fixing frame connection positioning body 1412 is an arc plate structure of a semi-cylindrical annulus that shapes the upper structural beam 101. The inner arc surface of the fixing frame connection positioning body 1412 is shaped and snapped onto the upper half of the upper structural beam 101. The two fixing frame mounting plates 1411 are respectively connected to the two sides of the outer arc surface of the arc plate structure of the fixing frame connection positioning body 1412, and the spacing between the two fixing frame mounting plates 1411 is not less than the width of the main beam 11, and can clamp the main beam 11 and be fixedly connected to the main beam 11.

[0055] The fixed frame connection power source 142 of this embodiment is a fixed frame steering gear, which is connected to the outer facade of a fixed frame mounting plate 1411. The output shaft of the fixed frame connection power source 142 passes through the fixed frame mounting plate 1411 and is movably connected to the fixed frame movable clamping plate 143 located between the two fixed frame mounting plates 1411. The rotation center of the fixed frame movable clamping plate 143 is provided with a rotation center hole. The fixed frame connection power source 142 can drive the fixed frame movable clamping plate 143 to rotate around the output shaft of the fixed frame connection power source 142.

[0056] The fixed frame movable clamping plate 143 of this embodiment is a semi-cylindrical arc plate structure matched with the fixed frame connection positioning body 1412. The fixed frame movable clamping plate 143 can be rotated to close with the fixed frame connection positioning body 1412 and be shaped to surround and cover the upper structural beam 101.

[0057] The two fixing frame connection units 14 can position and connect a main beam 11 to the upper structural beam 101 of the UAV landing gear 100 .

[0058] Preferably, the fixed frame connection power source 142 of this embodiment includes a fixed frame power output shaft 1421 with external teeth; the fixed frame movable clamping plate connection part 1431 is provided at the rotation center hole of the fixed frame movable clamping plate 143 of this embodiment, and the fixed frame movable clamping plate connection part 1431 is specifically an internal tooth hole with matching external teeth of the fixed frame power output shaft 1421. The gear pair formed by the fixed frame power output shaft 1421 and the fixed frame movable clamping plate 143 can ensure that the rotation power of the fixed frame connection power source 142 is stably transmitted to the fixed frame movable clamping plate 143, and the position is stable after the fixed frame movable clamping plate 143 rotates to the position and closes the arc plate structure with the fixed frame mounting plate 1411, so as to ensure that the main beam 11 is stably positioned and connected to the upper structural beam 101.

[0059] like Figure 4As shown, the axial positioning unit 12 of this embodiment includes two pairs of axial positioning card plates 121 arranged in groups, a total of four axial positioning card plates 121. The two pairs of axial positioning card plates 121 are symmetrically connected to the two sides of the main beam 11, and the two axial positioning card plates 121 of each group are symmetrically connected to the two oppositely arranged main beams 11 through the upper ends and the lower ends extend downward from the main beam 11. The two axial positioning card plates 121 of each group can jointly clamp and axially limit a fire bomb 200.

[0060] Preferably, the axial positioning unit 12 further includes an axial positioning connector 122. Multiple axial positioning connectors 122 are connected between each set of axial positioning card plates 121, together forming a fire-proof bomb upper clamping unit. The axial positioning connector 122 is specifically a steel pipe. Using axial positioning connectors 122 of different lengths can change the spacing of the main beam 11 to adapt to the mounting of fire-proof bombs 200 of different length specifications.

[0061] Further preferably, two axial positioning connectors 122 are connected between each group of axial positioning card plates 121, and the two axial positioning connectors 122 are symmetrically arranged on both sides of the axial positioning card plates 121; so that the axial positioning connectors 122 can avoid the upper part of the fireproof bomb 200 while enhancing the rigidity of the positioning unit on the fireproof bomb, thereby increasing the mounting height of the fireproof bomb 200 as much as possible, ensuring that the overall structure of the drone fireproof bomb mounting and delivery device of this embodiment is compact.

[0062] like Figure 4 and Figure 2 As shown, an axial positioning card plate fixing portion 1211 is provided at the lower portion of the axial positioning card plate 121; the lower surface of the axial positioning card plate fixing portion 1211 is similar to the shape / appearance of the fireproof bomb 200, specifically, a circular arc with a downward opening. In this embodiment, the axial positioning card plate fixing portion 1211 is fixed in the fireproof bomb fixing ring groove 201 of the fireproof bomb 200.

[0063] Preferably, the axial positioning card plate fixing portion 1211 is an arc plate structure with a certain axial width, which is equivalent to the arc at the lower part of the axial positioning card plate 121 being provided with flanges on both sides along the axial edge. Further preferably, the axial width of the axial positioning card plate fixing portion 1211 is not greater than the width of the fireproof bullet card ring groove 201. Even more preferably, the axial width of the axial positioning card plate fixing portion 1211 is equal to the minimum value of the width of the fireproof bullet card ring groove 201 to eliminate the influence of the root chamfer.

[0064] The inner diameter of the arc plate of the axial positioning card plate fixing part 1211 is not greater than the outer diameter of the fire-proof bullet locking ring groove 201. When the radius of the arc plate is equal to the outer diameter of the fire-proof bullet locking ring groove 201, the axial positioning card plate fixing part 1211 can safely axially position the card plate 121 with the maximum contact area with the fire-proof bullet 200; when the radius of the arc plate is less than the outer diameter of the fire-proof bullet locking ring groove 201, the axial positioning card plate fixing part 1211 can ensure contact with the fire-proof bullet 200 at the position of the two busbars.

[0065] This design can effectively improve the mounting stability of the fireproof bomb 200 while enabling the drone fireproof bomb mounting and delivery device of the same structure in this embodiment to be suitable for mounting multiple types of fireproof bombs within a certain range of diameter sizes.

[0066] The center distance between the arc plates of the axial positioning clamping parts 1211 of the two pairs of axial positioning clamping plates 121 is greater than the diameter of the mounted fireproof bomb 200.

[0067] like Figure 3 and Figure 4 As shown, the middle of the two main beams 11 of this embodiment are respectively connected with oppositely arranged fixed hook units 13, the upper end of the fixed hook unit 13 is connected to the main beam 11, and the lower end extends downward from the main beam 11. Each fixed hook unit 13 includes a fixed hanging plate 131 and a fixed hook 132; the fixed hook 132 is connected to the lower end of the fixed hanging plate 131.

[0068] In this embodiment, two fixing hooks 132 are arranged and connected along the X-axis direction at the lower end of the fixing hanging plate 131 ; each fixing hook 132 is connected to the second end of a movable mounting assembly 3 .

[0069] There can be one or two fixing hooks 132. Preferably, two fixing hooks 132 are selected in this embodiment.

[0070] like Figure 2 As shown, the decoupling assembly 2 is connected to the UAV landing gear 100 and is located between the two main beams 11 , and is preferably arranged in the middle position of the two main beams 11 .

[0071] like Figure 7 and Figure 8 As shown, the unhooking assembly 2 includes an unhooking mounting frame 21, an unhooking power source 22, an unhooking execution unit 23 and a slider 24. The unhooking mounting frame 21 is connected to the UAV landing gear 100; the unhooking power source 22 is connected to the outer facade of the unhooking mounting frame 21; the unhooking execution unit 23 is connected to the output part of the unhooking power source 22 in the unhooking mounting frame 21; and the slider 24 is connected in the unhooking mounting frame 21.

[0072] like Figure 7As shown, the unhooking mounting frame 21 of this embodiment is a shell structure, and the upper end of the unhooking mounting frame 21 can be connected to the upper structural beam 101 of the UAV landing gear 100 with an auxiliary connection structure.

[0073] like Figure 7 , Figure 8 and Fig. 9 As shown, the unhooking power source 22 is connected to the outer side elevation of the unhooking mounting frame 21 close to the inside, and the output shaft of the unhooking power source 22 is the unhooking power output shaft 221; the unhooking power output shaft 221 passes through the side wall of the shell structure of the unhooking mounting frame 21 and enters the shell of the unhooking mounting frame 21. The upper end of the unhooking execution unit 23 is connected to the unhooking power output shaft 221 inside the shell, and the lower end of the unhooking execution unit 23 extends out of the lower part of the unhooking mounting frame 21 to connect to the first end of the movable mounting assembly 3.

[0074] The slider 24 is connected to the inside of the unhooking mounting frame 21 and is located on the inner vertical surface of the housing side wall on the same side as the unhooking power source 22. The slider 24 can guide the displacement of the unhooking execution unit 23.

[0075] like Figure 8 and Fig. 9 As shown, the decoupling power source of this embodiment is a decoupling steering gear, and the decoupling power output shaft 221 of this embodiment is a decoupling steering gear output shaft with external teeth. The decoupling power source 22 of this embodiment is movably connected to the decoupling execution unit 23 through the decoupling power output shaft 221.

[0076] like Figure 8 and Fig. 9 As shown, the unhooking execution unit 23 includes a guide rod 232 ; a slide groove 241 is provided on the slider 24 ; and the lower end of the guide rod 232 is movably limited in the slide groove 241 .

[0077] The uncoupling execution unit 23 also includes a rocker arm 231; a rocker arm input connection part 2311 is provided at the upper end of the rocker arm 231; the rocker arm input connection part 2311 and the output part of the uncoupling power source 22 form a rotating pair; the uncoupling execution unit 23 also includes a uncoupling mechanism 233; the rocker arm 231, the guide rod 232 and the uncoupling mechanism 233 are hingedly connected in sequence.

[0078] The rocker arm 231 is a connecting rod with shaft holes at both ends. The upper end of the rocker arm 231 is provided with a rocker arm input connection part 2311, specifically an inner tooth hole at the upper end of the rocker arm 231 that matches the outer tooth of the unhooking power output shaft 221; the rocker arm input connection part 2311 and the unhooking power output shaft 221 form a rotation pair, specifically a gear pair. The shaft hole at the lower end of the rocker arm 231 is hinged to the upper end of the guide rod 232, and the lower end of the guide rod 232 is hinged to the upper end of the unhooking mechanism 233.

[0079] The lower end of the guide rod 232 can be movably limited on the slider 24, specifically, on the slide groove 241 provided on the slider 24 along the Z axis. Driven by the unhooking power source 22, the lower end of the guide rod 232 makes a linear displacement along the Z axis, driving the upper end of the unhooking mechanism 233 to also synchronously make a linear displacement along the Z axis, so that the lower end of the unhooking mechanism 233 performs an opening and closing action. The unhooking mechanism 233 can close the first end of the connection / open the release movable mounting assembly 3.

[0080] The unhooking mechanism 233 is a four-bar linkage; the upper ends of the two connecting rods at the upper part of the four-bar linkage are hinged to the lower end of the guide rod 232 to form the unhooking upper hinge point of the four-bar linkage; the lower ends of the two connecting rods at the upper part of the four-bar linkage are respectively hinged with the first unhooking body 2331 and the second unhooking body 2332 to form two unhooking intermediate hinge points.

[0081] The first dehooking body 2331 and the second dehooking body 2332 are specifically hook-shaped structures with a straight rod on the upper part and a curved rod with an arc-shaped hook on the lower part; the first dehooking body 2331 and the second dehooking body 2332 have the same structure. In the installed state, the two are cross-hinged in the middle to form a dehooking lower hinge point, and the arc-shaped hooks of the two are arranged opposite to each other.

[0082] Preferably, the side elevation of the lower end of the first decoupling body 2331 is provided with a first decoupling body engaging portion 23311, specifically a vertically penetrating boss provided in the middle of the side elevation; the side elevation of the lower end of the second decoupling body 2332 is provided with a second decoupling body engaging portion 23321, specifically a vertically penetrating groove provided in the middle of the side elevation.

[0083] This preferred design enables the gravity applied to the lock tongue by the movable mounting assembly 3 to avoid the gap between the first decoupling body 2331 and the second decoupling body 2332 when the fireproof bomb 200 is mounted, and is carried on the solid structure, and the gravity is shared by the first decoupling body 2331 and the second decoupling body 2332. This preferred design is conducive to improving the safety of mounting the fireproof bomb 200.

[0084] The working process of the four-bar linkage of the unhooking mechanism 233 is as follows:

[0085] The first decoupling body 2331 and the second decoupling body 2332 are hinged at the middle of their respective structures to form a second hinge point. The power is output through the decoupling power source 22 to output the rotational power → the rocker arm 231 generates a rotational motion → the guide rod 232 generates a rotational motion with the lower end limited to the displacement in the Z-axis direction / downward → the upper ends of the first decoupling body 2331 and the second decoupling body 2332 move up / down with the lower end of the guide rod 232 and generate a rotational motion around their respective second hinge points → the lower ends of the first decoupling body 2331 and the second decoupling body 2332 are closed to form a locking tongue / locking tongue opens → the first end of the movable mounting assembly 3 is locked / released.

[0086] One end of the movable mounting component 3 can be detachably connected to the decoupling component 2, and the other end of the movable mounting component 3 is connected to the fixed hook unit 13. The movable mounting component 3 limits the support of the lower part of the fireproof bomb 200; so that the fireproof bomb 200 is limited between the axial positioning card plate 121 and the movable mounting component 3.

[0087] like Figure 4 As shown, the movable mounting assembly 3 includes a movable mounting support body 31, a hanging rope 32 and a bullet holding belt 33; the two ends of the hanging rope 32 are symmetrically connected to the movable mounting support body 31, specifically located on both sides of the center point of the movable mounting support body 31, and the middle part of the hanging rope 32 is hung in the locking tongue; the two ends of the movable mounting support body 31 are respectively connected to the first end of a bullet holding belt 33; the second end of each bullet holding belt 33 is fixedly connected to the fixed hook unit 13 on the same side.

[0088] Specifically, the lengths of the lanyard 32 and the bomb belt 33 can be adjusted to maximize the mounting height of the fireproof bomb 200 and shorten the distance between the comprehensive center of mass of the fireproof bomb 200 and the center of mass of the drone in the mounted state, which is beneficial to improving the flight performance of the drone.

[0089] Preferably, the bullet holding belt 33 is a belt structure with a certain width, and the width of the bullet holding belt 33 is not greater than the width of the fireproof bullet card ring groove 201. Further preferably, the width of the bullet holding belt 33 is equal to the groove bottom width of the fireproof bullet card ring groove 201.

[0090] In this embodiment, only with regard to the Y-axial installation positioning of the center position of each structure, the installation distance of the first ends of the two bullet holding belts 33, the installation distance of the two axial positioning clamps 121 of the same group, and the installation distance of the two fixed hanging plates 131 are equal, and are equal to the spacing between the two fireproof bullet clamp ring grooves 201.

[0091] In this embodiment, the two decoupling assemblies 2 are arranged along the X-axis direction, and the spacing between them is greater than the sum of the diameters of the mounted fireproof bombs 200 , that is, the sum of the diameters of the mounted fireproof bombs 200 is smaller than the distance between the two opposite upper structural beams 101 .

[0092] The main structure of the utility model, such as the main beam 11, the axial positioning unit 12, etc., mostly adopts a shell and plate structure, and the bomb belt 33 of the utility model adopts a non-metallic material; these technical measures can effectively reduce the weight of the UAV fireproof bomb mounting and delivery device, which is beneficial to increase the effective load and improve the flight performance of the UAV.

[0093] The unmanned aerial vehicle fireproof bomb mounting and delivery device of the utility model is modularly configured, and can adapt to different unmanned aerial vehicles and / or different types of fireproof bomb mountings by replacing one or more structural parts such as the main beam, the axial positioning connector, the movable mounting support body, the fixed frame connecting unit, etc., and has a wide range of applicability.

[0094] The utility model can realize the synchronous clamping and automatic control of the installation and unloading process of the drone fireproof bomb mounting and delivery device on the drone landing gear 100 by setting a fixed frame connected to the power source 142; the operation steps are simplified and the reliability of the device clamping the fireproof bomb 200 is improved.

[0095] The utility model is provided with a decoupling power source 22, which can realize the automatic simultaneous / time-sharing decoupling and delivery of two decoupling components 2 arranged in the X-axis direction, so that multiple fireproof bombs 200 can be delivered simultaneously under the same device to improve delivery reliability and delivery efficiency; and the fireproof bombs 200 can be delivered accurately in batches to different operating areas in one flight to improve the operating range.

[0096] The above are only the preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited to them. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. At the same time, any equipment equipped with the device to expand the application field and produce complex technical effects belongs to the scope of protection of the utility model of the device.
