Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to an unmanned aerial vehicle (UAV) for intelligent inspection of hydropower stations. Background Art

[0002] The application of drones in the inspection of hydropower stations is gradually becoming an industry trend. They provide an efficient and safe inspection method with high cost-effectiveness. For example, in the inspection of dams and waters, drones can be equipped with high-resolution cameras to perform precise patrol missions, automatically detect potential safety issues such as cracks, and accurately measure the location and size of cracks. During the inspection of hydropower stations, drones may run out of power and fall, and the scale of the hydropower station has a significant impact on this risk. Large hydropower stations usually cover a wide area, have many buildings and equipment, and need to inspect a large area, which requires drones to fly longer distances and for longer periods of time, thereby increasing power consumption and increasing the risk of running out of power. At the same time, the terrain of large hydropower stations may be more complex, with more objects that may block signals, which may interfere with the signal transmission of the drone, resulting in the inability to accurately receive the return command, thereby increasing the risk of falling. If the inspection route planning is unreasonable, such as the flight distance is too long or the inspection time exceeds the battery life of the drone, it is easy to cause the battery to run out. In addition, if special circumstances are encountered during the inspection, such as complex meteorological conditions such as strong winds, the drone may consume more power to maintain stable flight, which may also cause the battery to run out prematurely.

[0003] To sum up, once a drone crashes, the consequences are very serious. Since drones usually fly at high speeds at high altitudes, once they lose control and fall rapidly to the ground, the body and its components will suffer serious damage, and such damage may render the drone unusable. In addition, if the drone unfortunately falls into the water, it will sink quickly due to its weight, resulting in the loss of the body and difficulty in recovering important data and equipment. Therefore, the present application provides a drone for intelligent inspection of hydropower stations to meet the needs. Summary of the invention

[0008] Optionally, a plurality of second air pipes are fixedly connected to the outer wall of the parachute, one ends of the plurality of second air pipes extend inwardly through the top of the parachute body and are connected to an air inlet opened on the top of the parachute body; a plurality of first air pipes are fixedly connected to the drone body, one ends of the plurality of first air pipes are connected to a pair of the landing gears, and the other ends of the plurality of first air pipes extend inwardly through the fixed shell; a plurality of through holes are opened on the lifting plate, one ends of a plurality of the through holes are connected to a plurality of the first air pipes, and the other ends of a plurality of the through holes are connected to a plurality of the second air pipes.

[0009] Optionally, an isolation layer is commonly fixed on the plurality of extrusion rods, the isolation layer comprises a plurality of folded portions, and the plurality of folded portions are located between the plurality of extrusion rods.

[0010] Optionally, the sizes of the plurality of third expansion pieces are adapted to the sizes of the plurality of second sliding grooves, and the plurality of third expansion pieces are located in the plurality of second sliding grooves to slide in a limited position.

[0011] Optionally, the protection component includes a fixing tube fixedly connected to a pair of the landing gears, a rubber body fixedly connected inside the pair of the fixing tubes, a second interface opened in the rubber body, the second interface is connected to a first interface opened at the bottom end of the pair of the landing gears, a movable rubber pad is fixedly connected between the first interface and the second interface, airbag rolls are fixedly connected to the opposite ends of the pair of the fixing tubes, and the pair of the airbag rolls are connected to the second interface.

[0012] Optionally, the aperture of the first interface gradually decreases toward the direction of the second interface to form a separating ring body, and the rubber pad is located at one end of the narrower aperture, a protrusion is fixedly connected to the bottom end of the second interface, a push rod is fixedly connected to the top end of the protrusion, and an extrusion ring is fixedly connected to the end of the push rod away from the protrusion.

[0013] Optionally, the bottom end of the rubber body is fixedly connected to a support portion, the bottom end of the support portion is fixedly connected to a plurality of sliding rods, the plurality of sliding rods all extend outward through the fixed tube and are fixedly connected to a floating plate, and the plurality of sliding rods are slidably connected to the fixed tube.

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

[0015] In the above scheme, by setting a deceleration component, when the battery is exhausted, the magnetism of the electromagnet ring disappears, causing the parachute to detach from the fixed shell. During the fall of the drone body, the pop-up parachute gradually opens, decelerating the falling speed of the drone body and increasing air resistance, greatly reducing the impact force of the drone body when it lands, thereby reducing the risk of damage to the drone body.

[0016] By providing a plurality of first expansion pieces, when the plurality of first expansion pieces are separated from the fixed shell, the top of the umbrella body can be driven to unfold, which is further conducive to the rapid unfolding of the above-mentioned umbrella body.

[0017] By setting up a protective component, after the parachute is opened, part of the air enters the airbag roll through a series of circulation. The unfolded airbag roll acts as a buoyancy bag to provide floating ability, which can protect the landing of the drone body after the fall. Since the buoyancy bag providing floating ability has buoyancy, when the drone body falls into the water, the buoyancy bag can make the drone body float, preventing the drone body from sinking to the bottom and being lost.

[0018] The above-mentioned deceleration component and protection component can cooperate to achieve a dual protection effect on the drone body. On the one hand, the deceleration component can reduce the falling speed of the drone body to prevent it from being damaged by high-speed impact. On the other hand, the protection component can buffer and protect the bottom of the drone body after landing. In addition, after the deceleration component is opened, it can also guide the falling drone body, so that the protection component on the landing gear can smoothly contact the water surface or the ground.

[0019] By setting up a float, on the one hand, after the drone body lands, the float can improve the buffering protection ability of the protective component; on the other hand, when the drone body lands, the float contacts the ground or water surface, which can prevent the leakage of internal air after the airbag is rolled up and unfolded, ensuring continuous floating ability.

[0047] like Figures 1 to 18 As shown, an embodiment of the present invention provides a drone for intelligent inspection of a hydropower station, including a drone body 1, a pair of landing gears 2 for support are fixedly connected to the bottom of the drone body 1; it also includes a deceleration component 3 for decelerating the drone body 1 during a fall, and a protection component 4 for protecting the drone body 1 after the fall, the deceleration component 3 and the protection component 4 are respectively mounted on the drone body 1 and the pair of landing gears 2.

[0048] like Figure 3 , Figure 6 and Fig.13As shown, the deceleration assembly 3 includes an umbrella body 9, a lifting plate 12, and a fixed shell 6 fixedly connected to the top of the drone body 1. The size of the umbrella body 9 is adjusted according to actual needs. A top cover 7 adapted to the fixed shell 6 is fixedly connected to the top of the umbrella body 9. When the top cover 7 is installed on the fixed shell 6, the two cooperate to form a rounded arc structure, which is beneficial to reduce the wind resistance of the drone body 1 during flight. A plurality of equidistantly arranged first expansion pieces 11 are fixedly connected to the peripheral edge of the top cover 7; wherein, the plurality of first expansion pieces 11 are fixed to the outer peripheral side wall of the umbrella body 9, and the top cover 7 is installed on the outer top of the umbrella body 9. The first expansion pieces 11 are made of hard material, and The first expansion piece 11 is connected to the top cover 7 by an elastic material, such as an elastic sheet. When the first expansion piece 11 is not subjected to stress, it remains in the expanded state. When the first expansion piece 11 bends inward, the elastic sheet connected to the top cover 7 is in a compressed state. The advantage of this arrangement is that in the initial state, a plurality of first expansion pieces 11 are embedded in the fixed shell 6, and the elastic sheet is in a compressed state, so that the top cover 7 can be installed in cooperation with the fixed shell 6, and the umbrella body 9 is also folded and compressed in the fixed shell 6. When the first expansion piece 11 is separated from the fixed shell 6, the first expansion piece 11 will return to its original position from the compressed state and drive the top of the umbrella body 9 to unfold, thereby helping the umbrella body 9 to unfold quickly.

[0049] like Figures 3 to 14As shown, the fixed shell 6 is fixedly connected with an electromagnet ring 8 and a fixed plate 22, the electromagnet ring 8 is close to the top of the fixed shell 6, the electromagnet ring 8 is connected in series with the battery and the voltage regulator in the drone body 1, the function of the voltage regulator is to ensure the stable matching of the voltage during the power-on process, when the battery is exhausted, the magnetism of the electromagnet ring 8 disappears, the above structure belongs to the prior art, and will not be repeated here; the top of the fixed plate 22 is fixedly connected with a plurality of equidistantly arranged second expansion pieces 23, the ends of the plurality of second expansion pieces 23 away from the fixed plate 22 are fixedly connected with third expansion pieces 24, the side walls of the fixed plate 22 are fixedly connected with a plurality of equidistantly arranged mounting portions 26, and the plurality of mounting portions 26 are rotatably connected There is an L-shaped extrusion rod 13, wherein the second expansion piece 23 is a V-shaped elastic structure, the third expansion piece 24 is a serrated structure composed of multiple V-shaped structures, and the third expansion piece 24 and the fixed plate 22 are respectively arranged at the upper and lower ends of the second expansion piece 23, and the three are an integrated structure; one end of the extrusion rod 13 is fixedly connected with a slide column 25, and the slide column 25 and the second slide groove 20 provided on the inner wall of the jacking plate 12 are limited and slidable, and the sizes of the third expansion pieces 24 and the second slide grooves 20 are adapted, and the third expansion pieces 24 are located in the second slide grooves 20 and are limited and slidable, and the other end of the extrusion rod 13 is fixedly provided with a first slide groove 17, and the limited sliding in the first slide groove 17 is a clamping rod 18, and the outer end of the clamping rod 18 rolls A ball 19 is connected, and when the lifting plate 12 is pressed down, the extrusion rod 13 is driven to rotate, so that the ball 19 contacts the clamping groove 16 opened in the fixed shell 6, wherein the fixed plate 22 is fixed to the bottom end of the fixed shell 6, the L-shaped extrusion rod 13 is hinged on the mounting portion 26 of the peripheral side wall of the fixed plate 22, and the third expansion piece 24 and the slide column 25 are both located in the second slide groove 20 on the inner wall of the lifting plate 12. The advantage of this arrangement is that in the initial position, a plurality of second expansion pieces 23 are unfolded, and when the first expansion piece 11 is installed in the fixed shell 6, it is in a compressed state. At the same time, the bottom end of the first expansion piece 11 will squeeze the lifting plate 12 to move it downward. At this time, the second expansion piece 23 is in a compressed state, and the L-shaped extrusion rod 13 is in a compressed state. The pressure rod 13 will also start to rotate due to the pressure of the lifting plate 12. During the rotation process, the sliding column 25 at one end of the extrusion rod 13 slides in the second slide groove 20 and applies pressure to the third expansion piece 24 to compress it; the clamping rod 18 at the other end of the extrusion rod 13 and a plurality of first expansion pieces 11 are magnetically matched with the electromagnet ring 8. When the first expansion piece 11 is installed in the fixed shell 6, they contact and are adsorbed by the inner wall of the electromagnet ring 8. At the same time, the clamping rod 18 slides upward under the magnetic effect of the electromagnet ring 8 and is stuck in the clamping groove 16, thereby preventing the extrusion rod 13 from resetting and driving the lifting plate 12 to push upward;Since the elastic force of the second expansion piece 23 and the third expansion piece 24 is greater than the elastic force of the first expansion piece 11, when the battery power is exhausted, the magnetism of the electromagnet ring 8 disappears, the first expansion piece 11 is no longer subject to magnetic constraints, and the extrusion rod 13 moves downward and resets under its own gravity. The ball 19 at the top slides in the clamping groove 16, which helps the extrusion rod 13 to reset. In this process, the second expansion piece 23 and the third expansion piece 24 in the compressed state reset and drive the lifting plate 12 to move upward, and the lifting plate 12 squeezes the first expansion pieces 11 in the fixed shell 6 when it is pushed upward, so that the parachute 9 is separated from the fixed shell 6. During the falling process of the drone body 1, the popped-up parachute 9 gradually opens to slow down the falling speed of the drone body 1. The realization of the above functions does not require additional sensor detection and control, does not consume excess power, and reduces the risk of damage to the drone body 1 due to falling. In addition, the outer wall of the top cover 7 can be set to a conspicuous material, such as a reflective sticker, which is conducive to finding the drone body 1 after it falls and facilitates subsequent salvage. ;

[0050] like Fig.15 As shown, an isolation layer 14 is fixed on the plurality of extrusion rods 13, and the isolation layer 14 includes a plurality of folding portions 15, and the plurality of folding portions 15 are located between the plurality of extrusion rods 13. The isolation layer 14 is made of thin rubber or other flexible materials. The advantage of such a configuration is that the isolation layer 14 is used to isolate the extrusion rods 13 from the umbrella body 9 to prevent the umbrella body 9 from being scratched or interfered by structures such as the extrusion rods 13 when the umbrella body 9 is folded and compressed into the fixed shell 6, thereby ensuring that the normal triggering of the umbrella body 9 is not affected.

[0051] like Figure 7 , Figure 8 and Figures 16 to 18As shown, the outer wall of the parachute body 9 is fixedly connected with a plurality of second air pipes 10, one end of the plurality of second air pipes 10 penetrates through the top of the parachute body 9 to extend inwardly, and is communicated with the air inlet 40 opened on the top of the parachute body 9; a plurality of first air pipes 5 are fixedly connected to the drone body 1, one end of the plurality of first air pipes 5 are connected to a pair of landing gears 2, and the other end of the plurality of first air pipes 5 penetrates through the fixed shell 6 to extend inwardly; a plurality of through holes 21 are opened on the lifting plate 12, one end of the plurality of through holes 21 are connected to the plurality of first air pipes 5, and the other end of the plurality of through holes 21 are connected to the plurality of second air pipes 10, and the protective component 4 includes a fixed pipe 27 fixedly connected to the pair of landing gears 2, a rubber body 28 is fixedly connected to the pair of fixed pipes 27, and a second interface 30 is opened in the rubber body 28, The second interface 30 is communicated with the first interface 29 opened at the bottom end of a pair of landing gears 2, and a movable rubber pad 37 is fixedly connected between the first interface 29 and the second interface 30. The opposite ends of a pair of fixed tubes 27 are fixedly connected with air bag rolls 39, and the pair of air bag rolls 39 are communicated with the second interface 30; wherein, the parachute 9 is connected to the through hole 21 on the top plate 12 through a plurality of second air pipes 10, and these second air pipes 10 are not only used as connecting ropes of the parachute 9, but also can be used as air ducts. The advantage of such a setting is that during the fall of the drone, when the parachute 9 is unfolded, part of the air will enter the second air pipe 10 through the air inlet 40 on the top of the parachute 9, and then flow into the first air pipe 5, and the air then enters the fixed air pipe 5 through the hollow structure of the landing gear 2. The rubber body 28 in the tube 27 eventually reaches the airbag roll 39 at both ends of the fixed tube 27. The airbag roll 39 is curled in the initial state. As air is injected, it gradually unfolds to form a buoyancy bag that provides floating ability, providing buffering protection for the drone body 1 after falling. Due to the buoyancy of the buoyancy bag that provides floating ability, the drone body 1 can float when it falls into the water during the inspection of the hydropower station, avoiding the sinking and loss of the drone body 1. The above-mentioned deceleration component 3 and protection component 4 can cooperate to achieve a dual protection effect on the drone body 1. On the one hand, the deceleration component 3 can reduce the falling speed of the drone body 1 to prevent it from being damaged by high-speed impact. On the other hand, the protection component 4 can buffer and protect the bottom of the drone body 1 after landing. In addition, the two cooperate to reduce the speed of the deceleration component 3. After the deceleration component 3 is opened, it can also guide the falling drone body 1, so that the protection component 4 on the landing gear 2 can smoothly contact the water surface or the ground; in addition, the cooperation between the deceleration component 3 and the protection component 4 provides double protection for the drone body 1. The deceleration component 3 can reduce the falling speed of the drone body 1 to avoid damage caused by high-speed impact; the protection component 4 provides buffer protection for the bottom of the drone body 1 after landing. The combination of the two, after the deceleration component 3 is unfolded, it can guide the falling drone body 1. After the deceleration component 3 is unfolded, it will always be located on the top of the drone body 1, so that the protection component 4 is always located at the bottom of the drone body 1, thereby ensuring that the protection component 4 can smoothly contact the water surface or the ground.

[0052] like Fig.17 As shown, the aperture of the first interface 29 gradually decreases toward the direction of the second interface 30, and a separating ring body 38 is formed, and the rubber pad 37 is located at one end of the narrower aperture, wherein one side edge of the rubber pad 37 is fixedly connected to the separating ring body 38. Since the rubber pad 37 is blocked by the separating ring body 38, it can only flip in one direction. By setting the separating ring body 38 and the rubber pad 37, when air enters the second interface 30 through the first interface 29, the rubber pad 37 between the two interfaces will be squeezed open, and when the air stops entering, the rubber pad 37 will be reset, thereby blocking the two interfaces and slowing down the leakage of air in the expanded and unfolded airbag roll 39.

[0053] like Figures 16 to 18 As shown, a protrusion 31 is fixedly connected to the bottom end of the second interface 30, a push rod 35 is fixedly connected to the top of the protrusion 31, and an extrusion ring 36 is fixedly connected to the end of the push rod 35 away from the protrusion 31, and a support portion 32 is fixedly connected to the bottom end of the rubber body 28, wherein the support portion 32 and the rubber body 28 are an integrated rubber structure, and a plurality of slide rods 33 are fixedly connected to the bottom end of the support portion 32, and the plurality of slide rods 33 all extend outward through the fixed tube 27 and are fixedly connected to a floating plate 34, and the plurality of slide rods 33 are slidably connected to the fixed tube 27, wherein the slide rod 33 and the fixed tube 27 are sealed and slidably connected, such as the sealed sliding structure between the piston and the piston cylinder in the prior art, which will not be described in detail here, and the function of the floating plate 34 is to, On the one hand, after the drone body 1 lands, the float 34 first contacts the ground, and the support portion 32 at the inner end of the float 34 is squeezed and compressed inward, thereby improving the buffering protection capability of the protective component 4; on the other hand, when the drone body 1 lands, the float 34 contacts the ground or water surface, and under the influence of gravity, the drone body 1 applies downward pressure, and at the same time, the support portion 32 at the inner end of the float 34 is squeezed inward, thereby pushing the top rod 35 and the extrusion ring 36 to move inward. This action causes the extrusion ring 36 to press tightly against the edge of the rubber pad 37, thereby enhancing the sealing effect of the first interface 29 and the second interface 30. Therefore, after the drone body 1 lands, it can prevent the leakage of internal air after the airbag roll 39 is unfolded, thereby ensuring continuous floating capability.

[0054] The working principle of the technical solution provided by the present invention is as follows: during installation, firstly, a plurality of first expansion pieces 11 on the side walls around the top cover 7 are pressed inward and inserted into the fixed shell 6, and the folding method of the umbrella body 9 under the top cover 7 is subject to the actual installation.

[0055] When the battery is exhausted, the magnetism of the electromagnet ring 8 disappears, causing the parachute 9 to separate from the fixed shell 6. During the falling process of the drone body 1, the pop-up parachute 9 gradually opens. The parachute 9 can decelerate the falling speed of the drone body 1 and increase the air resistance, thereby greatly reducing the impact force of the drone body 1 when it lands.

[0056] After the parachute body 9 in the above structure is opened, part of the air can enter the various air tubes through the air inlet 40 at the top of the parachute body 9 and enter the rubber body 28 in the fixed tube 27, so that the airbag roll 39 gradually expands and unfolds. The unfolded airbag roll 39 serves as a floating bag that provides floating ability, and can protect the landing of the drone body 1 after falling. Since the floating bag that provides floating ability has buoyancy, when the drone body 1 falls into the water, the floating bag can make the drone body 1 float, preventing the drone body 1 from sinking to the bottom and being lost.

[0057] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
