Description

Technical Field

[0001] The utility model belongs to the technical field of reservoir inspection drones, and particularly relates to an emergency landing protection device for reservoir inspection drones. Background Technique

[0002] Reservoirs, especially large reservoirs, are mainly used for water storage. The water resources stored in the reservoir are used to provide water for agricultural production, industrial production, and urban life. At the same time, power generation, flood control and other important functions can also be achieved through reservoir water storage.

[0003] During the use of the reservoir, it is necessary to regularly inspect the reservoir. On the one hand, through inspection, the reservoir and its resources can be protected from illegal damage and theft. More importantly, through the inspection of the reservoir, the safety status of the reservoir dam can be closely observed. Especially during heavy rain, the water level of the reservoir rises rapidly. If the risk of dam break of the reservoir dam is not discovered in time, extremely serious natural disasters will be caused.

[0004] For large reservoirs, due to the large area occupied by the reservoir, it is obviously impossible to conduct a full-range inspection of the reservoir manually. Therefore, in the actual work process, drones are mostly used to regularly inspect above the reservoir. During the inspection of large reservoirs by drones, once the battery power of the drone is insufficient and the drone cannot return to the reservoir shore, the drone can only fall into the reservoir and cannot be retrieved in the large reservoir.

[0005] At the same time, during the inspection of the reservoir by the drone, due to the influence of the reservoir on the signal of the drone, the signal reception intensity is not high during the inspection. Once the drone cannot receive the signal, the drone is very likely to lose control and fall.

[0006] Therefore, during the annual inspection of the reservoir, there are many cases where the drone falls into the reservoir due to insufficient power and weak signal. As an intelligent device, the purchase cost of the drone is relatively high. Undoubtedly, this defect leads to too high a cost for reservoir inspection. Even if a buoy is mounted on the drone for easy retrieval, after retrieval, the drone cannot be used normally due to water ingress and damage to the circuit components. Content of the Utility Model

[0044] Embodiment 1

[0045] As Figures 1-5 shown, a reservoir inspection UAV emergency landing protection device includes a UAV landing mechanism floating in the reservoir. When the UAV inspecting above the reservoir runs out of power or has a weak signal, the UAV landing mechanism is used to immediately shut down the UAV emergently to avoid falling into the reservoir.

[0046] Specifically, the UAV landing mechanism includes pontoons 1 arranged on the front and rear sides (the pontoons 1 are plastic cylinders with a middle hole inside, and their shape is: the pontoons 1 include a cylindrical part, and conical parts 11 are integrally formed at both ends of the cylindrical part. The structure of the conical parts 11 reduces the resistance during operation in water). A load-bearing frame 22 is fixedly assembled and connected between the above-mentioned pontoons 1. The specific structure is: the load-bearing frame 22 includes a main board part, convex board parts are integrally formed at the front and rear ends of the main board part respectively, and annular seats 21 fixedly installed on the pontoons 1 are respectively fixedly connected to the convex board parts (fastened by bolts).

[0047] At the same time, a UAV carrying box is fixedly connected to the top of the above-mentioned load-bearing frame 22; the UAV carrying box is used for loading the box body 5 of the UAV, and waterproof covers 51 are hinged on both sides of the top of the box opening of the box body 5 and are arranged in cooperation on both sides.

[0048] The specific method is: the same as the existing hinge structure of the cover body, hinge seats 535 arranged at intervals on both sides are fixedly connected to the top of the box body 5, and the lower end of the waterproof cover 51 is hinged on the hinge seat 535 through a pin shaft.

[0049] At the same time, the waterproof cover 51 is driven by a gear structure to flip open or close. Specifically, the gear structure includes a driven gear 531 installed on the waterproof cover 51 (the driven gear 531 is fixedly connected to the lower end position of the rear side wall of the waterproof cover 51 through a connecting shaft), the driven gear 531 meshes with a driving gear 532, and the driving gear 532 is assembled and connected with a motor 533.

[0050] The installation method of the motor 533 is: a motor installation groove is opened on the side wall of the box body 5, the motor 533 is assembled in the motor installation groove, the motor installation groove is fixedly connected with a groove cover 534, and the output shaft of the motor 533 is rotatably connected to the groove cover 534 (the groove cover is fastened by bolts, the same as the existing rotation connection method, and a bearing for rotatably connecting the output shaft is installed on the groove cover 534).

[0051] During the working process, when the UAV cannot fly from above the reservoir to the shore due to insufficient power, at this time, the UAV is controlled to drive towards the nearest UAV landing mechanism (multiple UAV landing mechanisms are floatingly arranged in the reservoir to facilitate the emergency landing of the UAV), and it drives and lands in the box body 5. Subsequently, driven by the motor, the driving gear 532 drives the driven gear 531 to rotate, and the waterproof covers 51 on both sides are covered. During the covering process, waterproofing is achieved. Specifically, when the UAV landing mechanism travels in the water to the shore, water is prevented from entering the box body 5 through the covered waterproof covers 51.

[0052] Embodiment 2

[0053] As Figures 1-5As shown, on the basis of the structure of Embodiment 1, in order to achieve that when the drone falls into the box body 5, the waterproof cover 51 automatically closes. According to the existing conventional method, a sensor 52 for controlling the operation of the motor is installed at the bottom inside the box body 5, specifically a pressure sensor. When the drone falls onto the sensor 52, the motor operates at this time to drive the box body 5 to close.

[0054] The above method of controlling the motor through the sensor is a conventional method of motor control work disclosed in the prior art. Specifically, it is the same as the existing method. The sensor is electrically connected to the controller, and the controller is electrically connected to the motor to achieve control work.

[0055] Embodiment 3

[0056] As Figures 1-5 shown, on the basis of the structure of Embodiment 1, in order to achieve a high sealing performance after the waterproof cover 51 is closed, the above waterproof covers 51 are locked through a locking structure. Specifically, the locking structure includes a plurality of lock tongues 54 fixedly connected to the left waterproof cover 51. Correspondingly, lock holes 55 adapted to the lock tongues 54 are provided on the right waterproof cover 51. And the lock tongues 54 and the lock holes 55 are connected through an elastic buckle structure.

[0057] The elastic buckle includes elastic lock protrusions 541 elastically assembled on the side walls on both sides of the lock tongue 54. (Specifically, the elastic buckle structure is a conventional elastic lock buckle structure disclosed in the prior art, which is the same as the existing elastic lock buckle structure. Sliding grooves adapted to the side walls on both sides of the lock tongue 54 are provided, and the lower end of the elastic lock protrusion 541 is slidably connected to the sliding groove, and elastic expansion and contraction are realized through a small spring fixedly connected in the sliding groove.) Lock grooves 551 adapted to the elastic lock protrusions 541 are provided on the hole side wall of the lock hole 55 (the upper end of the elastic lock protrusion 541 is hemispherical, adapted to the hemispherical lock groove 551, and the purpose is to facilitate detachment after locking); when the lock tongue 54 is inserted into the lock hole 55, the elastic lock protrusion 541 is elastically squeezed and elastically limited in the lock groove 551.

[0058] During the detachment process, under the drive of an electric shock, the lock tongue 54 on the flipped waterproof cover 51 slides relative to the lock groove, and the curved elastic lock protrusion 541 is more likely to detach from the lock groove 551 during the relative sliding process. During the relative sliding and detachment from the lock groove 551, the elastic lock protrusion 541 elastically expands and contracts under the action of a small spring (not shown in the figure).

[0059] Embodiment 4

[0060] As Figures 1-5As shown, based on the structure of Example 3, the emergency landing protection device for reservoir inspection UAV further includes an emergency network connection mechanism installed at the top of the parking frame 22. The emergency network connection mechanism is used to catch the falling UAV when the UAV loses signal or the power is insufficient to support it to fly into the box 5.

[0061] Specifically, the emergency network connection mechanism includes four rectangularly distributed grid rods 4; a nylon net bag 41 is fixedly connected between the tops of the grid rods 4, and the nylon net bag 41 is located above the drone carrying box. There is enough clearance between the nylon net bag 41 and the box 5, so that the drone can fall into the box 5 easily.

[0062] Once the drone signal is lost, or the power is insufficient to support the drone to fly into the box 5, the drone will fall into the nylon net bag 41 to easily hold the drone.

[0063] Specifically, since the nylon net bag 41 has a certain area, it can effectively catch the falling drone.

[0064] Example 5

[0065] like Figures 1-5 As shown, based on the structure of Example 4, this embodiment is the same as the existing propeller-driven walking mode on the hull in the water, and two propeller mechanisms are installed on the right side wall of the above-mentioned parking frame 22 with intervals in front and behind. Specifically, it is the same as the existing propeller-driven walking mode on the hull. The above-mentioned propeller mechanism includes a motor mounting frame 3, a driving motor is installed in the motor mounting frame 3, and the driving motor is installed with a motor housing 32 (the motor housing 32 plays a role in sealing and protecting the motor, the motor housing 32 is installed on the motor mounting frame 3, and the motor mounting frame 3 is fixed on the side wall of the parking frame 22), and a driving shaft is installed on the output shaft of the driving motor (the driving shaft is rotatably connected to the motor housing 32, and a sealed bearing is installed on the motor housing 32 in the same way as in the existing sealing method), and a propeller 31 is installed on the end of the driving shaft. Same as the existing method, during the driving process of the propeller 31, the entire device travels in the water.

[0066] This method is designed to carry the drone to the shore when the drone is in the process of being caught. When the drone is about to fall, the drone can be driven close to the shore. If the operator finds that the drone has low battery and weak signal on the shore, the entire device can be immediately lowered and driven to the vicinity of the drone.

[0067] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
