Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a long-endurance water surface patrol UAV. Background Technology

[0002] A surface patrol drone is an unmanned aerial vehicle specifically designed for tasks such as monitoring, patrolling, and collecting data on water surfaces.

[0003] With the development of drone technology, it has been gradually introduced into engineering water surface inspection work. However, existing drones face the severe challenge of insufficient endurance. The vast water surface of engineering projects means that drones need to fly multiple times in the same water area for a long time to complete a comprehensive inspection mission. However, the battery capacity and energy density of mainstream drones are limited, and the endurance after a single charge is short, which is difficult to meet the needs of long-distance and long-duration inspections. Frequent returns to the base for charging not only consume a lot of time and reduce inspection efficiency, but also increase labor costs and operational complexity.

[0004] Therefore, a long-endurance surface patrol drone is needed. Utility Model Content

[0005] The main objective of this invention is to provide a long-endurance surface patrol drone that can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A long-endurance water surface patrol drone includes a patrol drone body, with landing gear fixedly connected to the lower left and right sides of the patrol drone body. A floating device is installed on the lower part of the outer surface of each of the two landing gears. A float seat device is provided at the lower part of the patrol drone body, and a traction mechanism is fixedly connected to the lower outer ring array of the float seat device.

[0008] Preferably, the flotation device includes two fixed blocks located on the lower front and rear sides of the outer surface of the landing gear. The lower ends of the two fixed blocks are fixedly connected to a flotation chamber. The upper ends of the two fixed blocks are provided with connecting plates. The fixed blocks and connecting plates located on the same side are connected by bolts. The interior of the flotation chamber is hollow.

[0009] Preferably, the floating base device includes a charging floating base and a wireless module. The charging floating base is located at the lower part of the patrol drone body, and a power transmission pile is fixedly connected to the middle of the upper end of the charging floating base. The wireless module is fixedly connected to the middle side of the lower part of the patrol drone body. The charging floating base is hollow inside, and a storage battery is installed in the inner cavity of the charging floating base.

[0010] Preferably, the three traction mechanisms are fixedly connected to the lower outer ring of the charging float.

[0011] Preferably, the traction mechanism includes a fixed base, which is fixedly connected to the lower outer ring of the charging float. A winding wheel is rotatably connected to the inner cavity of the fixed base. A traction rope is wound around the outer surface of the winding wheel. A traction hammer is fixedly connected to the lower part of the traction rope. A stepper motor is fixedly connected to the rotating shaft of the winding wheel. A waterproof shell for protecting the stepper motor is fixedly connected to the end of the fixed base connected to the stepper motor.

[0012] Preferably, the stepper motor is fixedly connected to the mounting base.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This device, through its designed floating base and traction mechanism, allows the floating base to float on the waters patrolled by the patrol drone. The traction mechanism then stabilizes the floating base in its designated position, preventing it from drifting with water surface fluctuations and improving its stability.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1, as Figure 1 and Figure 2 As shown, a long-endurance water surface patrol drone includes a patrol drone body 1. Landing gears 2 are fixedly connected to the lower left and right sides of the patrol drone body 1. Floating devices 5 are installed on the lower outer surface of both landing gears 2. A floatation device 3 is provided at the lower part of the patrol drone body 1. A traction mechanism 4 is fixedly connected to the lower outer ring array of the floatation device 3.

[0025] Before implementation, the float device 3 is placed on the water surface to be inspected, so that the float device 3 floats on the water surface. Then, the three traction mechanisms 4 are activated to raise and lower the float device 3, so that the float device 3 extends to the bottom of the water and is pulled to float on the water surface.

[0026] In the above, before the patrol drone body 1 patrols the water surface, the floating device 5 must be installed on the lower part of the landing gear 2.

[0027] After the float device 3 is placed and the floating device 5 is installed, the patrol drone 1 can be started to work, allowing the patrol drone 1 to patrol the water surface. When water sampling is required, the patrol drone 1 can be controlled to float downwards. The floating device 5 makes the patrol drone 1 float on the water surface, and then the patrol drone 1 can be remotely controlled to sample the patrolled water. After sampling, the floating device 5 can be used to float on the water surface, allowing the patrol drone 1 to patrol the lower parts of the water surface, reducing the power consumption of the patrol drone 1, extending its battery life, eliminating the need for frequent charging, and thus improving the patrol efficiency of the patrol drone 1.

[0028] In the above-mentioned scenario, when the battery of the patrol drone 1 is almost depleted, the patrol drone 1 can be controlled to fly to the upper part of the float device 3. After reaching the upper part of the float device 3 vertically, the patrol drone 1 can be controlled to float vertically downwards, so that the patrol drone 1 lands on the float device 3. Then, the patrol drone 1 is wirelessly charged through the float device 3, so that the patrol drone 1 does not need to fly to the shore to charge, reducing the time it takes for the patrol drone 1 to fly back to the shore each time. This allows the patrol drone 1 to charge in the patrolled waters, thereby improving the working efficiency of the patrol drone 1.

[0029] In a further embodiment, to achieve the purpose of mounting the flotation device 5 on the landing gear 2 so that the patrol drone body 1 can float on the water surface via the flotation device 5, see [reference needed]. Figure 3 The floating device 5 includes two fixing blocks 52, which are located on the front and rear sides of the lower part of the outer surface of the landing gear 2. The lower ends of the two fixing blocks 52 are fixedly connected to the floating chamber 51. The upper ends of the two fixing blocks 52 are provided with connecting plates 53. The fixing blocks 52 and connecting plates 53 located on the same side are connected by bolts 54. The floating chamber 51 is hollow inside.

[0030] In the above process, firstly, two fixing blocks 52 are attached to the lower part of the outer surface of the landing gear 2 to make the floatation tank 51 initially connected to the landing gear 2. Then, the connecting plate 53 is attached to the fixing blocks 52. Finally, the fixing blocks 52 and the connecting plate 53 are connected together by bolts 54, thereby fixing the floatation tank 51 to the landing gear 2.

[0031] As described above, after the floating chamber 51 is fixed on the landing gear 2, when the UAV needs to float on the water surface, the patrol UAV body 1 can be controlled to descend downwards, so that the floating chamber 51 contacts the water surface. Through the hollow design of the floating chamber 51, the purpose of floating the patrol UAV body 1 on the water surface can be achieved, so that the patrol UAV body 1 can take water samples or patrol low-lying areas, so that the patrol UAV body 1 does not have to be in flight all the time, reducing the power consumption required by the patrol UAV body 1.

[0032] Furthermore, in order to achieve the purpose of wirelessly charging the patrol drone body 1 by the floating base device 3, refer to... Figure 4 The floating device 3 includes a charging floating seat 31 and a wireless module 33. The charging floating seat 31 is located at the lower part of the patrol drone body 1. A power transmission pile 32 is fixedly connected to the middle of the upper end of the charging floating seat 31. The wireless module 33 is fixedly connected to the middle side of the lower part of the patrol drone body 1. The charging floating seat 31 is hollow inside, and a battery is installed in the inner cavity of the charging floating seat 31.

[0033] Furthermore, the three traction mechanisms 4 are fixedly connected to the lower outer ring of the charging float 31.

[0034] In the above, the wireless module 33 adopts the principle of electromagnetic induction. There is a transmitting coil in the power transmission pile 32. When AC power is applied, an alternating magnetic field is generated. When the receiving coil on the patrol drone body 1 is close to the power transmission pile 32, an induced electromotive force is generated under the action of the alternating magnetic field, which in turn generates an induced current in the receiving coil. After being processed by rectification, voltage regulation and other circuits, it charges the battery of the patrol drone body 1.

[0035] In the above process, when the patrol drone body 1 needs to be charged, the drone is first controlled to fly to the upper middle part of the charging float 31, and then the patrol drone body 1 is controlled to descend so that the wireless module 33 makes contact with the power transmission pile 32. When the wireless module 33 and the power transmission pile 32 are in contact, the battery in the charging float 31 will transmit the current to the wireless module 33 through the power transmission pile 32. Then the wireless module 33 will transmit the current to the patrol drone body 1 to charge the patrol drone body 1. This allows the patrol drone body 1 to be charged without flying to the shore, and the patrol drone body 1 can replenish its power during the patrol process, thereby improving the endurance of the patrol drone body 1.

[0036] As described above, the charging float 31 is hollow, which allows the charging float 31 and the power transmission pile 32 to float on the water surface. The traction mechanism 4 then stabilizes the charging float 31 in its placement position, preventing it from floating with the fluctuations of the water surface.

[0037] Furthermore, in order to ensure that the traction mechanism 4 stabilizes the charging float 31 in its placed position and prevents the charging float 31 from floating with the water surface fluctuations, refer to... Figure 5 The traction mechanism 4 includes a fixed base 41, which is fixedly connected to the lower outer ring of the charging float 31. A winding wheel 42 is rotatably connected to the inner cavity of the fixed base 41. A traction rope 43 is wound around the outer surface of the winding wheel 42. A traction hammer 44 is fixedly connected to the lower part of the traction rope 43. A stepper motor 45 is fixedly connected to the rotating shaft of the winding wheel 42. A waterproof shell 46 for protecting the stepper motor 45 is fixedly connected to one end of the fixed base 41 connected to the stepper motor 45.

[0038] Furthermore, the stepper motor 45 is fixedly connected to the mounting base 41;

[0039] Furthermore, the traction hammer 44 is cone-shaped.

[0040] In the above, the stepper motor 45 is powered by a battery installed in the charging float 31.

[0041] In the above description, after the charging float 31 is placed in the required position, the three stepper motors 45 can be started to work, so that the output ends of the three stepper motors 45 rotate simultaneously. When the output ends of the stepper motors 45 rotate, their output ends will drive the connected winding wheel 42 to rotate in the inner cavity of the fixed seat 41 through the coupling. When the winding wheel 42 rotates, it will release the traction rope 43 from the winding wheel 42. Then, due to the influence of the gravity of the traction hammer 44, the traction rope 43 will be pulled taut. At this time, the traction hammer 44 will also descend. When the traction hammer 44 descends to the bottom of the water, the stepper motors 45 can be turned off. The traction hammer 44 and the traction rope 43 will pull the charging float 31, so that the charging float 31 will not drift randomly.

[0042] As described above, the charging float 31 can be stabilized on the water surface to the greatest extent by the traction of the three traction hammers 44.

[0043] In the above, the waterproof housing 46 is used to protect the stepper motor 45, so that water will not come into contact with the stepper motor 45, thereby improving the safety of the stepper motor 45.

[0044] It should be noted that the specific installation method, circuit connection method, and control method of the stepper motor 45 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
