Technical Field

[0001] The utility model relates to the field of earthquake search and rescue, and specifically, to an earthquake search and rescue device based on an unmanned aerial vehicle (UAV). Background Art

[0002] UAVs play an important role in earthquake search and rescue. After an earthquake occurs, ground traffic is often blocked, the environment of the ruins is complex and dangerous, and it is difficult for personnel to quickly reach certain areas for search and rescue. With its unique advantages, a UAV can quickly respond and start working. Its main functions include: rapid reconnaissance, being able to quickly fly to the disaster area, and through devices such as high-definition cameras and thermal imagers carried on it, quickly obtain large-area images of the disaster area, helping rescue personnel understand the overall disaster situation, including the range of building collapses, road blockage conditions, etc. Detection of vital signs, equipped with life detection sensors such as acoustic detectors and infrared sensors, can detect sounds, body temperatures and other vital signs emitted by survivors under the ruins, providing accurate target positions for rescue operations. Communication relay, in areas where communication facilities are damaged, the UAV can serve as a temporary communication relay station to expand the communication coverage range and ensure the smooth flow of information between rescue personnel and the command center. Material delivery, it can deliver urgently needed medicines, food, drinking water and other materials to trapped areas that are difficult to reach, providing timely assistance to survivors. Assessment of dangerous areas, entering areas that may be dangerous, such as near buildings about to collapse, assessing the degree of danger, providing a decision-making basis for the actions of rescue personnel, and reducing unnecessary casualties.

[0003] During the search and rescue process, UAVs are often in a relatively harsh environment, especially in areas with more dust. When a UAV passes through an area with a large amount of dust, the dust will enter the interior through the outer shell of the UAV, thereby affecting the operation of its internal electronic components and further affecting the stability of the UAV's operation.

[0004] Therefore, we make improvements in this regard and propose an earthquake search and rescue device based on a UAV. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0033] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] Please refer to Figure 1 - Figure 5 , a seismic search and rescue device based on a drone, including a housing 1. A support rod 101 is fixedly connected to the upper surface of the housing 1. The other end of the support rod 101 is fixedly connected to a hydraulic rod 102. The movable end of the hydraulic rod 102 is fixedly connected to a collection bucket 103. A chute 104 is arranged on the side of the collection bucket 103. An air delivery pipe 105 is slidably connected to the inner wall of the chute 104. A through hole 106 is arranged at a position close to the upper end of the inner wall of the chute 104. A plurality of ventilation slots 107 are annularly arranged on the side of the collection bucket 103 directly above the through hole 106. The other end of the air delivery pipe 105 communicates with a flow guide plate 108. An opening 109 is arranged on the surface of the flow guide plate 108 close to the air delivery pipe 105.

[0035] When cleaning the surface of the housing 1, when the drone is flying, its propeller 6 rotates. The rotation of the propeller 6 generates wind energy. The generated wind energy enters the air delivery pipe 105 along the opening 109. Then the hydraulic rod 102 moves downward, driving the collection bucket 103. When the collection bucket 103 slides downward, the through hole 106 on its surface abuts against the air delivery pipe 105. At this time, the wind energy enters the collection bucket 103 along the air delivery pipe 105 and the through hole 106. The wind energy entering the interior of the collection bucket 103 is discharged to the surface of the housing 1 along the ventilation slots 107 due to the pressure in the bucket, realizing the cleaning of the housing 1.

[0036] A movable rod 2 is fixedly connected to the lower surface of the collection bucket 103. The movable rod 2 is a variable-diameter pipe and contracts from the lower end to the upper end. A bolt 201 is fixedly connected to the lower surface of the movable rod 2.

[0037] The movable rod 2 fixedly connected to the lower surface of the collection bucket 103 can realize the contraction of the movable plate 3 through sliding. The movable rod 2 is set as a variable-diameter pipe so that the movable plate 3 can slide and reset. When the movable rod 2 slides downward, the movable plate 3 slides towards each other due to the stretching of the spring 4. Similarly, when the movable rod 2 moves upward, the movable plate 3 slides in the opposite direction.

[0038] The outer surface of the movable rod 2 abuts against a movable plate 3. The movable plate 3 passes through the side surface of the housing 1 and is slidably connected thereto. A connecting rod 301 is fixedly connected to the lower surface of the movable plate 3. The connecting rod 301 is L-shaped, and a sleeve 302 is fixedly connected to the horizontal portion of the connecting rod 301. There are two sleeves 302, and any one sleeve 302 is slidably connected to the inner wall of the other sleeve 302. Jacks 303 are provided on the upper surfaces of the two sleeves 302.

[0039] The movable plate 3 abutting against the outer surface of the movable rod 2 is used to control the sliding of the connecting rod 301. The sliding of the connecting rod 301 can drive the sliding of the sleeve 302. The sliding of the sleeve 302 can make it slidably connected and achieve socketing. When the movable rod 2 slides downward, it drives the downward sliding of the bolt 201. When the sleeve 302 achieves socketing, the jacks 303 provided on the upper surface of the sleeve 302 are aligned. At this time, the bolt 201 slides downward and is inserted into the jack 303 to achieve the docking and fixation of the connecting rod 301. After the connecting rod 301 is fixed, the device to be transported can be clamped to the fixed rod through a buckle, and at this time, the fixed transportation of the device is achieved.

[0040] A spring 4 is fixedly connected to the surface of the movable plate 3 close to the movable rod 2. The other end of the spring 4 is fixedly connected to the side surface of another movable plate 3.

[0041] The spring 4 fixedly connected to the surface of the movable plate 3 close to the movable rod 2 is used to pull the movement, thereby realizing the opposite sliding of the connecting rod 301. When the movable rod 2 slides downward, the surface of the movable plate 3 loses abutment. Due to the elastic action, the spring 4 will pull the movable plate 3. During the pulling process of the movable plate 3, it drives the sliding of the connecting rod 301. The sliding of the connecting rod 301 can drive the sliding of the sleeve 302.

[0042] The flow guide plate 108 is arc-shaped, and a baffle 5 is fixedly connected to the upper surface of the flow guide plate 108.

[0043] The flow guide plate 108 is set to be arc-shaped. On the one hand, it can adapt to the rotation radius of the propeller 6. On the other hand, it can converge the generated wind energy to the opening 109 and convey the wind energy. The baffle 5 fixedly connected to the upper surface of the flow guide plate 108 can prevent the generated wind energy from overflowing, so that the collected wind energy cannot achieve the effect of cleaning the housing 1.

[0044] A propeller 6 is provided directly below the baffle 5. The propeller 6 is provided directly above the housing 1.

[0045] The propeller 6 provided directly below the baffle 5 can generate wind energy by rotating. The generated wind energy enters the inside of the air delivery pipe 105 and the collection barrel 103 through the opening 109 for exhaust cleaning.

[0046] The usage process of a seismic search and rescue device based on a drone provided by the present utility model is as follows:

[0047] When cleaning the outer shell 1, wind energy is generated by the rotation of the propeller. The generated wind energy enters the air duct 105 along the opening 109. Then, the hydraulic rod 102 moves downward, driving the collection bucket 103. When the collection bucket 103 slides downward, the through holes 106 on its surface abut against the air duct 105. At this time, the wind energy enters the collection bucket 103 along the air duct 105 and the through holes 106. The wind energy entering the interior of the collection bucket 103 is discharged to the surface of the outer shell 1 along the ventilation grooves 107 due to the pressure inside the bucket, realizing the cleaning of the outer shell 1;

[0048] When fixing the materials, the downward sliding of the movable rod 2 drives the downward sliding of the bolt 201. When the socket 302 is sleeved, the jacks 303 provided on the upper surface of the socket 302 are aligned. At this time, the bolt 201 slides downward and is inserted into the jacks 303, realizing the docking and fixing of the connecting rod 301. After the connecting rod 301 is fixed, the materials to be transported can be clamped on the fixing rod through the buckle, realizing the fixed transportation of the materials.
