Description

Technical Field

[0001] This utility model relates to the field of drone firefighting technology, specifically to a drone hose laying device. Background Technology

[0002] With the widespread application of drone firefighting technology, the limitations of traditional hose laying, which relies on manual handling, are becoming increasingly apparent.

[0003] Current fire hose laying methods heavily rely on manual labor and coordinated operations, requiring multiple people to work together to complete processes such as unfolding and securing. In dangerous or complex terrains such as steep slopes, ruins, and forests, the following significant drawbacks exist:

[0004] 1. Low efficiency, high dependence on manpower, requires multiple people to work together, slow laying speed, may delay the golden time for fire fighting in emergency fire, and high personnel safety risks in dangerous scenarios;

[0005] 2. Due to terrain limitations, it is inefficient in dangerous areas such as steep slopes and ruins. Traditional methods cannot be quickly deployed in areas that are difficult to reach by manpower, such as the vertical surfaces of high-rise buildings and canyons. Utility Model Content

Detailed Implementation

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1-3 As shown, the drone hose laying device according to an embodiment of the present invention includes a housing 10, a fixing frame 20, and a damping component 50.

[0029] like Figure 1 As shown, there is at least one housing 10, and at least one housing 10 is detachably and fixedly connected to the fixing frame 20. The housing 10 is used to store the fire hose 80. The housing 10 is fixed to the drone by the fixing frame 20. The housing 10 can adopt an aluminum alloy frame structure with partitions to ensure strength while reducing the overall weight.

[0030] like Figures 2-3 As shown, in some embodiments, there are three boxes 10, which are stacked and connected in a detachable manner. The width and height of the multiple boxes 10 can be consistent, and the lengths of the multiple boxes 10 can be unequal or equal. However, the stacked boxes 10 should be symmetrical in the middle to ensure the uniformity of the overall weight distribution and reduce the impact of uneven gravity on the control of the drone. Preferably, the length of each box 10 can be set to increase sequentially from top to bottom.

[0031] like Figures 1-3As shown, the mounting bracket 20 is detachably and fixedly connected to the housing 10. The base 21 can be fixed to the bottom of the lowest housing 10 with bolts and is equipped with anti-loosening washers. The base 21 and the housing 10 are symmetrical in the middle. Multiple connecting rods 22 are symmetrically and evenly distributed along the length of the housing 10. The bottom of the connecting rod 22 is fixed to the edge of the base 21 that extends out of the bottom of the housing 10, and the top of the connecting rod 22 extends upward above the uppermost housing 10 to facilitate the connection and fixation of the drone.

[0032] like Figure 3 As shown, the preferred base 21 is grid-shaped, which improves the load-bearing strength while reducing the weight of the fixing frame 20 to a certain extent.

[0033] like Figures 2-3 As shown, to further ensure the reliability of the fixed connection between the fixing frame 20 and the multiple boxes 10, the connecting rod 22 can be fixed to the side end face of the box 10 by bolts.

[0034] like Figures 1-5 As shown, a plurality of connectors 30 are fixed to the bottom of the housing 10, and a plurality of second connecting holes 70 are provided at the upper position of the side end face of the housing 10 along the length direction. The second connecting holes 70 can be fixed to the connectors 30 at the bottom of the housing 10 above by locking members 40.

[0035] Furthermore, such as Figures 2-5 As shown, the connector 30 is preferably a hinge. The connector 30 includes a fixed hinge and a movable hinge. The fixed hinge is fixed to the bottom of the housing 10 by bolts. The movable hinge has a first connecting hole 31. The movable hinge can rotate in the space below the bottom of the housing 10. The upper and lower adjacent housings 10 are connected by locking members 40 in sequence to the first connecting hole 31 of the upper housing 10 and the second connecting hole 70 of the lower housing 10 to form a detachable and fixed connection. The locking member 40 is preferably a bolt, and it is also equipped with an anti-loosening washer. Threads adapted to the locking member 40 are provided in both the first connecting hole 31 and the second connecting hole 70.

[0036] Furthermore, such as Figure 4 As shown, first connecting holes 31 can be made at the same corresponding positions on the fixed and movable pages of the connector 30. The connector 30 can be installed on the housing 10 as a binding member, without disassembly when not in use or when not in use. When not in use, the hinge can be completely folded, and the first connecting holes 31 on the movable page and the first connecting holes 31 on the fixed page can be connected in sequence with the locking member 40 (e.g., ...). Figure 3 As shown in the figure, this also serves to store the locking part 40, reducing the risk of losing small parts; when in use, there is no need to operate the connector 30 and locking part 40 stored on the bottom box 10, just unscrew the locking part 40 above the bottom box 10 and then install it to connect the adjacent box 10.

[0037] In some embodiments, such as Figure 7 As shown, two adjacent boxes 10 can be slidably connected along the length of the box 10. For example, a slide rail is provided at the bottom of the upper box, and a corresponding matching slide groove is provided at the top of the lower box. After two adjacent boxes 10 are slidably installed in a suitable position, the relative position of the connecting rod 22 to each box 10 can be fixed by bolt connection.

[0038] like Figures 4-5 As shown, a second opening is provided on the top of the housing 10. The second opening communicates with the cavity. The second opening facilitates the rearrangement and storage of the used water hose after the device is used in fire rescue operations, so that it can be stored for the next use.

[0039] like Figures 4-5 As shown, the box body 10 is provided with a first support bar 11 and a second support bar 12 inside, and the cover plate 60 can be fixed to the first support bar 11 and the second support bar 12 by bolts.

[0040] like Figures 4-5 As shown, the box body 10 has a cavity inside. A first opening is provided on one side of the box body 10 along its length direction, and the first opening communicates with the cavity. A plate-shaped damping member 50 can be fixed to the first opening on the side of the box body 10 by adhesive or bolts. A first opening 51 and a second opening 52 are provided at the lower end of the damping member 50. The first opening 51 and the second opening 52 are connected. The damping member 50 can be made entirely of damping rubber material or a rigid material with damping rubber strips embedded at the edge of the opening.

[0041] like Figure 1 , Figure 2 and Figure 6 As shown, the fire hose 80 stored in the bottommost box 10 is laid out in a rectangular wave pattern starting from the hose head 81 inside the box 10. After reaching the innermost side of the box 10, the hose end 82 is led out in a straight line from the left side inside the bottommost box 10. The hose end 82 of the lower box 10 extends to the upper box 10 and becomes the hose head 81 of the upper box 10. The fire hose 8 is laid out in each box 10 in this way until it extends to the uppermost box 10. The hose end 82 of the uppermost box 10 is stored inside the box 10. The hose head 81 passes through the second opening 52, and the hose end 82 passes through the first opening 51.

[0042] Furthermore, such as Figures 1-2As shown, the height of the second opening 52 increases sequentially from left to right. During use, the fire hose 80 slides out from the second opening 52. By controlling the drone to yaw and rotate slightly, the position of the fire hose 80 within the second opening 52 can be adjusted. If the fire hose 80 slides out too quickly, the drone is controlled to yaw to the left, driving the entire device to move the fire hose 80 towards the lower position within the second opening 52 to achieve deceleration in the high-damping zone. If the fire hose 80 slides out too slowly, the drone is controlled to yaw to the right, driving the entire device to move the fire hose 80 towards the higher position within the second opening 52 to achieve acceleration in the low-damping zone, thereby adjusting the speed of hose laying.

[0043] To better understand the working principle of this solution, a stacked structure with multiple layers of boxes 10 in some embodiments is used as an example, such as... Figure 2 and Figure 6 As shown, during use, after reaching the most suitable water outlet (fire truck) or water intake point (natural water source) from the fire scene, connect the drone to the device. Then, pull out a section of the water hose starter 81 (i.e., the sleeping bag starter) from the second opening 52 in the bottommost housing 10 and fix the starter. Afterward, control the drone to drive the device along the water hose laying path to start laying the water hose synchronously. During the laying process, the fire hose 80 slides out from the second opening 52 of the bottommost housing 10. In laying sections with complex terrain, control the drone to veer to the left to drive the entire device, so that the fire hose 80 moves closer to the second opening 52. The lower position within the second opening 52 achieves deceleration in the high-damping zone, and the drone is simultaneously controlled to decelerate to prevent the fire hose from stacking. On flat laying sections, the drone can be controlled to veer to the right to drive the entire device, causing the fire hose 80 to move towards the higher position within the second opening 52 to achieve acceleration in the low-damping zone. The drone is simultaneously controlled to accelerate, improving the laying efficiency of the fire hose 80. After the fire hose 80 in the lowest box 10 is laid, under the influence of the drone's pulling force, the fire hose 80 in the lowest box 10 can slide out from the connection between the first opening 51 and the second opening 52. Then, the laying of the fire hose 80 in the upper box 10 is started in the same way.

[0044] In practical use, this device can be customized to store fire hoses 80 of different lengths according to the size of the box 10 and the number of stacked boxes.
