[0025] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Such as Figures 1 to 6As shown in the figure, a load-bearing structure for a fire-fighting drone includes a lower mounting plate 1. A first bracket 2 is fixedly connected to the bottom of the lower mounting plate 1. A first stepping motor 3 is fixedly connected to the inner wall of the first bracket 2. The output end of the first stepping motor 3 is fixedly connected to a first rotating shaft 4. A first hollow plate 5 is fixedly connected to the surface of the first rotating shaft 4. An outer cylinder 6 is fixedly connected to the surface of the first hollow plate 5. An inlet / outlet 7 is provided on the upper surface of the outer cylinder 6. A second bracket 8 is fixedly connected to the bottom of the lower mounting plate 1. A second stepping motor 9 is fixedly connected to the inner wall of the second bracket 8. The output end of the second stepping motor 9 is fixedly connected to a second rotating shaft 10. An inner cylinder 11 is fixedly connected to the surface of the second rotating shaft 10. A partition plate 12 is fixedly connected to the surface of the inner cylinder 11. Second hollow plates 13 are fixedly connected to the front surface of the partition plate 12 and the surface of the inner cylinder 11. The surfaces of the second hollow plates 13 and the surface of the partition plate 12 are in contact with the inner wall of the outer cylinder 6. The back surface of the partition plate 12 and the back surface of the inner cylinder 11 are in contact with the front surface of the first hollow plate 5.

[0028] Among them, the number of partition plates 12 is four, and the four partition plates 12 are symmetrically distributed with the inner cylinder 11 as the center. Arc-shaped columns 14 are fixedly connected to the front surface of the first bracket 2 and the back surface of the second bracket 8. The upper surface of the arc-shaped column 14 is in contact with the inner wall of the outer cylinder 6. The outer cylinder 6 can be supported through the arc-shaped column 14, thereby effectively reducing the pressure on the first rotating shaft 4 and the second rotating shaft 10. Reinforcing blocks 17 are fixedly connected to the surface of the partition plate 12 and the surface of the inner cylinder 11. Through the reinforcing blocks 17, the fixation between the partition plate 12 and the inner cylinder 11 becomes more firm.

[0029] It should be noted that by arranging four partition plates 12 in the outer cylinder 6, four fire-fighting items can be placed in the outer cylinder 6. At the same time, through the first stepping motor 3, the position of the inlet / outlet 7 can be changed. Through the second stepping motor 9, the partition plate 12 can rotate in the outer cylinder 6. When transporting fire-fighting items, the inlet / outlet 7 can be rotated to the directly above, so that the fire-fighting items will not fall during the transportation process. When the inlet / outlet 7 is rotated to the upper left, firefighters can place the fire-fighting items into the outer cylinder 6 through the inlet / outlet 7. When the inlet / outlet 7 is rotated to the lower left, through the rotating partition plate 12, the four fire-fighting items in the cylinder can fall out of the inlet / outlet 7 in sequence.

[0030] As Figures 1 to 8 shown in the figure, a translation mechanism 15 is fixedly connected to the upper surface of the lower mounting plate 1. An upper mounting plate 16 is fixedly connected to the upper surface of the translation mechanism 15.

[0031] Among them, the translation mechanism 15 includes a rectangular cylinder 151, an electric push rod 152, a connecting block 153, a U-shaped plate 154, an upper guiding column 155 and a lower guiding column 156. The upper surface of the rectangular cylinder 151 is fixedly connected to the bottom of the upper mounting plate 16. The inner wall of the rectangular cylinder 151 is fixedly connected to the right end of the electric push rod 152. The left ends of the electric push rods 152 are fixedly connected to the right side of the connecting block 153. The front and rear sides of the connecting block 153 are in contact with the inner wall of the rectangular cylinder 151. The bottom of the connecting block 153 is fixedly connected to the inner wall of the U-shaped plate 154. The inner wall of the U-shaped plate 154 is in contact with the upper surface of the rectangular cylinder 151. The front and rear sides of the inner wall of the U-shaped plate 154 are fixedly connected to the surface of the upper guiding column 155. The front and rear sides of the rectangular cylinder 151 are fixedly connected to the surface of the lower guiding column 156. The upper surface of the lower guiding column 156 is in contact with the bottom of the upper guiding column 155.

[0032] It should be noted that the electric push rod 152 can control the left and right movement of the connecting block 153. At the same time, through the cooperation of the upper guiding column 155 and the lower guiding column 156, the U-shaped plate 154 can be supported, and the acting force on the connection between the connecting block 153 and the U-shaped plate 154 can be effectively reduced, so that the connection between the connecting block 153 and the U-shaped plate 154 is more firm. When the inlet and outlet 7 rotates to the upper left, the translation mechanism 15 can stagger the inlet and outlet 7 rotated to the upper left from the body of the fire-fighting drone, and it is convenient for firefighters to place fire-fighting items into the outer cylinder 6 through the inlet and outlet 7.

[0033] The working principle of the present utility model is as follows: First, the upper mounting plate 16 is fixed to the bottom of the fire-fighting drone. Then, through the electric push rod 152, the outer cylinder 6 is moved to the left by a certain distance, and through the first stepping motor 3, the inlet and outlet 7 is rotated to the upper left. At this time, the inlet and outlet 7 located in the upper left is staggered from the body of the drone. Then, firefighters place fire-fighting items into the outer cylinder 6 through the inlet and outlet 7. After the placement is completed, through the second stepping motor 9, the partition plate 12 is rotated. At this time, the fire-fighting items are staggered from the inlet and outlet 7. Then, firefighters can continue to place the next fire-fighting item into the outer cylinder 6.

[0034] After four fire-fighting items are placed, through the electric push rod 152, the outer cylinder 6 is returned to the initial position, and through the first stepping motor 3, the inlet and outlet 7 is rotated to the due upper position. Then, the fire-fighting items in the outer cylinder 6 are transported by the fire-fighting drone.

[0035] When the fire-fighting drone reaches the fire-fighting and rescue point, first, the first stepping motor 3 is used to turn the inlet and outlet 7 to the lower left, and the fire-fighting items located on the left side of the inner cylinder 11 fall from the inlet and outlet 7. Then, the fire-fighting drone is remotely controlled to fly to the next fire-fighting and rescue point. When reaching the next fire-fighting and rescue point, the second stepping motor 9 is used to rotate the partition plate 12. At this time, through the partition plate 12, the fire-fighting items below the inner cylinder 11 are rotated to the left side of the inner cylinder 11, and the fire-fighting items fall from the inlet and outlet 7 through the inclined partition plate 12.

[0036] Finally, when all the fire-fighting items in the outer cylinder 6 are delivered, the fire-fighting drone is remotely controlled to return.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
