Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection technology, specifically relating to a drone pipeline inspection device. Background Technology

[0002] Drone pipeline inspection is a new method that utilizes drone technology to inspect, monitor, and maintain pipelines. This technology is typically used for inspecting long-distance, hard-to-reach pipeline facilities such as oil and gas pipelines, water supply pipelines, and power pipelines. Drone inspection offers advantages over traditional manual or ground-based inspections.

[0003] Problems with existing technology:

[0004] When floods occur, large amounts of water and debris such as branches sometimes flood the pipes, making the situation inside the pipes very complicated. Sometimes the exit is blocked, and the open space is blocked by branches. This makes it difficult for the drone's battery to maintain its original range under such circumstances. If the water is flowing, it may also block its retreat, making it unable to return or deviating from its original plan to continue looking for an exit. Utility Model Content

[0005] The purpose of this invention is to provide a drone pipeline inspection device. By using a shrink cover and a serrated plate design, the drone can reduce its size by tightening its wings when encountering narrow passages, thus attempting to pass through them. At the same time, the design of the detachable base allows the drone to be selectively installed. By using the detachable base in conjunction with the drone, the drone can move inside the pipeline or stay on the water surface with only a small amount of power, effectively reducing the drone's power consumption and thus dealing with possible accidents.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A drone pipeline inspection device includes: a body, a shrink cover on the top of the body, multiple wings slidably disposed on the outer side of the body corresponding to the shrink cover, and a disassembly base detachably installed at the bottom of the body;

[0008] A helical toothed plate is fixedly connected to the side of the wing near the shrinking cover. A sliding groove is provided on the fuselage corresponding to the position of the helical toothed plate. The helical toothed plate is slidably installed in the sliding groove. The bottom of the shrinking cover is engaged with the helical toothed plate.

[0009] The fuselage has an air inlet at the position of one of the wings, the disassembly base has an interface at the position of the air inlet, and the disassembly base has an air outlet on the side of the interface.

[0010] A motor is fixedly installed at the top center of the machine body, and the output end of the motor is fixedly connected to the shrink cover.

[0011] A T-shaped slider is fixedly installed at the bottom of the machine body, and a T-shaped groove is fixedly connected to the top of the disassembly base. The T-shaped groove is inserted into the T-shaped slider.

[0012] The end of the machine body is fixedly connected to a support lug 1, and the disassembly base is fixedly connected to a support lug 2 below the support lug 1. The support lug 2 and the support lug 1 are connected by bolts through internal threads.

[0013] The interface is connected to the air outlet, and balance blocks are fixedly installed on both sides of the detachable base.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention, through the design of a shrink cover and a serrated plate, enables a drone to reduce its size by tightening its wings when encountering narrow passages, thus allowing it to attempt to pass through such passages.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1 As shown, a UAV pipeline inspection device includes: a body 1, a shrink cover 2 on the top of the body 1, multiple wings 3 slidably disposed on the outer side of the body 1 corresponding to the shrink cover 2, and a disassembly base 4 detachably installed at the bottom of the body 1.

[0026] The body 1 is the body of the drone, the shrink cover 2 is used to move the wing 3 closer to the top of the body 1 to reduce its size, and the detachable base 4 is used to enable the drone to stay and float on the water surface.

[0027] See attached document Figures 2-4 A helical toothed plate 301 is fixedly connected to the side of the wing 3 near the shrink cover 2. A sliding groove is provided on the fuselage 1 at the position corresponding to the helical toothed plate 301. The helical toothed plate 301 is slidably installed in the sliding groove. The bottom of the shrink cover 2 is engaged with the helical toothed plate 301. A motor 302 is fixedly installed at the top position in the middle of the fuselage 1. The output end of the motor 302 is fixedly connected to the shrink cover 2.

[0028] According to the above structure, when encountering a narrow passage, the drone can drive the shrinking cover 2 to rotate by starting the motor 302. Through the threaded connection between the bottom of the shrinking cover 2 and the helical tooth plate 301, the wing 3 is moved closer to the top of the body 1. At this time, about one-third of the projected area of ​​the wing 3 overlaps with the body 1, which reduces the diameter of the drone and allows it to attempt to pass through the narrow passage. In this new situation, two-thirds of the projected area of ​​the wing 3 does not overlap with the body 1, allowing the drone to still fly, but the motor driving the wing 3 to fly needs to output more power. The shrinking cover 2 has a ring on the side, and the bottom of the ring is set with progressive threaded protrusions. The top of the helical tooth plate 301 has a corresponding threaded groove. The two are meshed and connected. During the rotation, the threaded protrusion pushes the threaded groove in the thread direction, causing the helical tooth plate 301 to slide.

[0029] See attached document Figures 2-5The fuselage 1 has an air inlet 101 at the position of one of the wings 3. The disassembly base 4 has an interface 401 at the position of the air inlet 101. The disassembly base 4 has an air outlet 402 on one side of the interface 401. A T-shaped slider 103 is fixedly installed at the bottom of the fuselage 1. A T-shaped groove 404 is fixedly connected to the top of the disassembly base 4. The T-shaped groove 404 and the T-shaped slider 103 are inserted and installed. A support ear 102 is fixedly connected to the end of the fuselage 1. A support ear 2 405 is fixedly connected to the disassembly base 4 at the position below the support ear 102. The support ear 2 405 is connected to the internal thread of the support ear 102 by a bolt 406. The interface 401 is connected to the air outlet 402. Balance blocks 403 are fixedly installed on both sides of the disassembly base 4.

[0030] Based on the above structure, due to the complex internal conditions of the pipes after water is poured in, it is necessary to conserve power and prepare for any unexpected situations. In this case, the disassembly base 4 can be connected. First, the T-shaped groove 404 and the T-shaped slider 103 of the disassembly base 4 are slidably installed. Then, the first support 102 and the second support 405 are threaded together via the second support 405 to make it more secure. Then, the drone, along with the disassembly base 4, is placed on the water surface. When it encounters calm water, one of the wings 3 near the interface 401 is activated. One-third of the wing 3 overlaps with the projection of the fuselage 1, generating airflow. This airflow enters the air inlet 101 and then into the interface 4. 01 The airflow is ejected from the vent 402, propelling the drone and the detachable base 4 forward. The remaining two-thirds of the airflow is blown towards the water surface, providing some propulsion. When encountering obstacles on the water surface, the drone can take off and pass over the obstacles, thus saving power. When the drone is blocked at both ends by debris brought by the water flow, the drone can rely on the detachable base 4 to float steadily on the water surface, waiting for the obstacles to be removed or for rescue. The balance block 403 is used to maintain the stability of the drone on the water surface. At the same time, the even distribution of the balance block 403 can make the center of the detachable base 4 stable through the filling material, so that the drone will not tilt due to the center of gravity when it takes off.

[0031] The working principle of this utility model is as follows: the body 1 is the body of the drone, the shrink cover 2 is used to move the wing 3 closer to the top of the body 1 to reduce its volume, and the detachable base 4 is used to enable the drone to stay and float on the water surface; when encountering a narrow passage, the drone can drive the shrink cover 2 to rotate by starting the motor 302, and move the wing 3 closer to the top of the body 1 through the threaded connection between the bottom of the shrink cover 2 and the inclined tooth plate 301, so that it can be connected to the detachable base 4. When encountering a calm water surface, one of the wings 3 near the interface 401 is activated, and one-third of the wing 3 overlaps with the projection of the body 1 to generate airflow. The airflow enters the air inlet 101 and then enters the interface 401 and is ejected from the air outlet 402, propelling the drone and the detachable base 4 forward. The other two-thirds of the airflow blows towards the water surface to play a certain role in propulsion. When encountering obstacles on the water surface, it can take off and fly over the obstacles, thereby saving power.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
