Description

Technical Field

[0001] The present invention relates to the technical field of pipeline detection, and more specifically, to a pipeline detection device using an unmanned aerial vehicle. Background Art

[0002] Pipeline inspection is an important means to ensure the safe and reliable operation of pipeline systems. It involves regular inspection and maintenance of various types of pipelines (such as oil, natural gas, water, chemical materials, etc.). The main purpose of pipeline inspection is to find the location of problems inside the pipeline, such as corrosion, blockage, leakage, etc., and take timely measures to repair or replace the problematic pipeline parts.

[0003] When inspecting the inside of pipelines, especially buried pipelines, it is very time-consuming and laborious for staff to judge and find problem points alone, and it is impossible to find the problem points quickly and easily. Therefore, drones are usually operated to enter the pipelines for inspection, especially in some complex locations. Drones carry various sensors and cameras to enter the pipelines for inspection and can transmit real-time images, videos and other relevant data to the control center, which can improve inspection efficiency and quality while reducing labor costs and risks.

[0004] However, when current drones are patrolling and inspecting inside pipelines, it is easy for the drones to collide with the inner wall of the pipeline or fall due to improper operation or poor signals, which can easily cause the drones to malfunction and be damaged. The protection is poor, and the mobile patrol is not stable enough, which affects the detection effect. Moreover, when the drone malfunctions and cannot move, it is inconvenient to remove it from the pipeline, which is time-consuming and labor-intensive, and the use effect is not good.

[0005] Therefore, it is necessary to provide a UAV pipeline inspection device to solve the above technical problems. Summary of the invention

[0024] An adjusting column and two sleeve columns, wherein the two sleeve columns are slidably sleeved on both sides of the adjusting column, one of the sleeve columns is connected to the drone body, and the other sleeve column is connected to the adapter;

[0025] A fixing hole is formed on the adjusting column, and a fastening bolt matching the fixing hole is threadedly connected to the sleeve column.

[0026] Furthermore, a sliding cavity is opened inside one of the sleeves, and a connecting column is slidably connected to the inner wall of the sliding cavity. One end of the connecting column is connected to the adapter seat, and a reset member is arranged between the other end and the inner wall of the sliding cavity.

[0027] Furthermore, a shift groove is provided on the inner wall of the sliding cavity, and a limiting sliding block connected to the connecting column is slidably arranged in the shift groove.

[0028] Furthermore, it also includes a connecting shaft and a transmission component rotatably arranged on the support plate, the bottom of the connecting shaft is connected to the camera, and the transmission component is used to drive the connecting shaft to rotate.

[0029] Furthermore, the transmission component includes a second driving member arranged on the support plate, the output end of the second driving member is provided with a first gear, and the upper end of the connecting shaft is provided with a second gear meshing with the first gear.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-10 The unmanned aerial vehicle pipeline detection device includes an unmanned aerial vehicle body 1 and further includes:

[0050] A support plate 2 is arranged below the drone body 1, and a camera 3 and a lighting lamp 4 are arranged at the bottom of the support plate 2;

[0051] A traction rope 5, one end of which is connected to the support plate 2 and the other end of which is located outside the pipeline;

[0052] A retracting and releasing mechanism 6 is provided on the support plate 2 and is used for retracting and releasing the traction rope 5;

[0053] There are four connecting members 7, which are respectively arranged obliquely on both sides of the drone body 1;

[0054] The adapter seat 8 is connected to the end of the connecting member 7, and a ball 9 is rotatably embedded on the side of the adapter seat 8 away from the connecting member 7.

[0055] When in use, the device is placed at the entrance of the pipeline to be inspected, so that the ball 9 on the adapter 8 of the drone body 1 contacts the inner wall of the pipeline, and the ball 9 can roll on the adapter 8, and then the drone body 1 can be operated to move toward the inside of the pipeline. The four connecting parts 7 are arranged on both sides of the drone body 1 at an angle, and the ball 9 on the adapter 8 at the end of the connecting part 7 can roll along the inner wall of the pipeline, so that the drone body 1 can move stably and smoothly inside the pipeline for inspection, thereby making the inspection process of the drone body 1 more stable and improving the quality and effect of the inspection; and through the cooperation of each connecting part 7 and the ball 9, the drone body 1 can be prevented from falling or colliding with the inner wall of the pipeline due to improper operation or poor signal, the drone body 1 is well protected, the failure and damage of the drone body 1 are reduced, the service life and performance thereof are improved, and the drone body 1 has high practicality.

[0056] The drone body 1 can transmit images, videos and other data in real time through the camera 3 and other sensors in the pipeline, so that the staff can accurately and effectively detect and judge the inside of the pipeline. The lighting 4 can increase the brightness in the dark environment of the pipeline, making it more convenient for the staff to check.

[0057] When the drone body 1 moves toward the inside of the pipeline, the traction rope 5 is also released by the retracting and releasing mechanism 6, that is, one end of the traction rope 5 is outside the entrance of the pipeline, and the retracting and releasing mechanism 6 of the drone body 1 releases the wound traction rope 5 while moving toward the inside of the pipeline. When the drone body 1 fails in the pipeline and cannot move, the traction rope 5 can be pulled outside the pipeline to drive the drone body 1 to move outside the pipeline, and finally the failed drone body 1 can be taken out of the pipeline. The operation is simple and convenient, and the phenomenon that the drone body 1 is inconvenient to be taken out due to the failure of the drone body 1 in the deep of the pipeline is prevented, which saves a lot of time and labor, has high work efficiency, good use effect, and can be widely promoted and used.

[0058] When the drone body 1 moves out of the pipeline after the inspection, the retracting mechanism 6 will simultaneously wind the traction rope 5, which can prevent the traction rope 5 from being left in the pipeline, greatly reducing the occurrence of entanglement and knotting, and reducing the subsequent manual retraction operation, saving time and effort. And after the traction rope 5 is rolled up by the retracting mechanism 6, the movement and storage of the drone body 1 can be facilitated, avoiding clutter and having strong flexibility. And after the drone body 1 is pulled out by the traction rope 5 due to a malfunction, the traction rope 5 can also be rolled up by the retracting mechanism 6, which is simple and convenient.

[0059] In this embodiment, preferably, please refer to Figure 1 and Figure 7-9 , the retracting and releasing mechanism 6 comprises:

[0060] A vertical plate 61 is disposed on the support plate 2, and a rotating shaft 62 is rotatably disposed on the vertical plate 61;

[0061] A rope drum 63 is provided on the rotating shaft 62, and the traction rope 5 is wound and connected to the rope drum 63;

[0062] The driving component 64 is used to drive the rotating shaft 62 to rotate.

[0063] When the drone body 1 moves into the pipeline for inspection, the driving component 64 is disconnected from the rotating shaft 62. Since one end of the traction rope 5 is outside the pipeline, when the drone body 1 is extended into the pipeline, the traction rope 5 on it will drive the rope drum 63 and the rotating shaft 62 to rotate due to the tension, so that the traction rope 5 on the rope drum 63 will gradually be released, keeping the traction rope 5 always connected to the drone body 1. At this time, the driving component 64 is not needed, which not only reduces the instability of the operation of the driving component 64, but also enables the traction rope 5 to better follow the drone body 1 to perform the line release operation, and the use effect is good.

[0064] When the drone body 1 needs to be moved out after the inspection, the driving component 64 will be connected to the rotating shaft 62, and then the driving component 64 will drive the rotating shaft 62 to rotate, and the rotating shaft 62 will cause the rope drum 63 to rotate, so that the rope drum 63 will wind up the winding traction rope 5, and the traction rope 5 will gradually become shorter and be wound around the rope drum 63 to achieve the winding effect, effectively avoiding the situation where the traction rope 5 is tangled, facilitating the subsequent movement and storage, and also facilitating the next detection and use of the device.

[0065] In this embodiment, preferably, please refer to Figure 7-9 , the driving component 64 includes:

[0066] The first driving member 641 is arranged at the upper end of the support plate 2. The output end of the first driving member 641 is connected to the telescopic member 642. The end of the telescopic member 642 is connected to the plug post 643. The plug post 643 is provided with a limit assembly 645. The plug hole 644 is opened at one end of the rotating shaft 62 and is adapted to the plug post 643. The first driving member 641 in the present application can adopt a servo motor, and the telescopic member 642 can adopt an electric telescopic rod or a cylinder. When it is necessary to connect with the rotating shaft 62, the plug post 643 can be extended by the telescopic member 642, that is, the plug post 643 is inserted into the plug hole 644 of the rotating shaft 62, and the position of the plug post 643 is limited by the limit assembly 645. After that, the telescopic member 642, the plug post 643 and the rotating shaft 62 can be driven to rotate by starting the first driving member 641, thereby driving the rope drum 63 to rotate. When it is necessary to disconnect from the rotating shaft 62 , the plug post 643 is retracted through the telescopic member 642 , that is, the plug post 643 is separated from the insertion hole 644 of the rotating shaft 62 .

[0067] In this embodiment, preferably, please refer to Figure 8-9 The limiting component 645 includes an inner groove 6451 opened in the plug column 643, the inner wall of the inner groove 6451 is slidably connected to the limiting block 6452, and an elastic member 6453 is provided between the end of the limiting block 6452 and the inner wall of the inner groove 6451; a limiting groove 10 matching the limiting block 6452 is opened in the socket 644.

[0068] The elastic member 6453 in the present application can be a spring. When the plug post 643 is inserted into the socket 644, if the limit groove 10 in the socket 644 is not in the position of the limit block 6452, the limit block 6452 will be squeezed by the socket 644, and the limit block 6452 will be pressed to move into the inner groove 6451 and compress the elastic member 6453. Then, when the first driving member 641 rotates the plug post 643, when the limit block 6452 rotates to the position of the limit groove 10, the limit block 6452 is no longer compressed, and the limit block 6452 is reset by the elastic member 6453, and the limit block 6452 will eventually enter the limit groove 10, thereby connecting the plug post 643 and the rotating shaft 62, that is, when the plug post 643 rotates, it will drive the rotating shaft 62 to rotate together.

[0069] In this embodiment, preferably, please refer to Figure 1-3 and Figure 5-7 , the connecting member 7 comprises:

[0070] An adjusting column 72 and two sleeve columns 71, wherein the two sleeve columns 71 are respectively slidably sleeved on both sides of the adjusting column 72, wherein one sleeve column 71 is connected to the drone body 1, and the other sleeve column 71 is connected to the adapter 8;

[0071] The fixing hole 73 is formed on the adjusting column 72 , and a fastening bolt 74 matching the fixing hole 73 is threadedly connected to the sleeve column 71 .

[0072] After the fastening bolt 74 is screwed to disengage the fixing hole 73, the adjusting column 72 can be telescopically moved along the inside of the sleeve column 71, thereby changing the distance between the two sleeve columns 71, and then changing the extension distance of the adapter seat 8 and the ball 9, and then adjusting the extension distance of the adapter seat 8 and the ball 9 according to the pipes with different inner diameters, that is, the ball 9 can always be in contact with the inner wall of the pipe, which has strong flexibility and can be adaptively adjusted according to different pipe size specifications, and has high practicality. After the adjustment is completed, the fastening bolt 74 can be screwed to enter the corresponding fixing hole 73 to complete the fixation between the adjusting column 72 and the sleeve column 71.

[0073] The connecting piece 7 is also detachably connected to the drone body 1 and can be installed as needed. When not in use, the connecting piece 7 can be removed for easy storage and transportation.

[0074] In this embodiment, preferably, please refer to Figure 1-3 and Figure 5-7, a sliding cavity 11 is provided inside one of the sleeve columns 71, and a connecting column 12 is slidably connected to the inner wall of the sliding cavity 11, one end of the connecting column 12 is connected to the adapter 8, and a reset member 13 is arranged between the other end and the inner wall of the sliding cavity 11, and the reset member 13 includes a damper 131 and a spring 132. When the drone body 1 moves inside the pipeline, the ball 9 of the adapter 8 will move along the inner wall of the pipeline, and when encountering protruding impurities or obstacles on the inner wall of the pipeline, the adapter 8 and the ball 9 will be squeezed, and the adapter 8 will make the connecting column 12 move toward the sliding cavity 11, and compress the reset member 13, so that the adapter 8 and the ball 9 will move accordingly to adapt to the uneven condition of the inner wall of the pipeline, reducing interference with the movement of the drone body 1. And the damper 131 and the spring 132 of the reset member 13 can play the role of resetting and partially buffering the adapter 8 and the ball 9, reducing the damage to the adapter 8 and the ball 9.

[0075] In this embodiment, preferably, please refer to Figure 6 The inner wall of the slide cavity 11 is provided with a shifting groove 14, and a limiting slider 15 connected to the connecting column 12 is slidably arranged in the shifting groove 14. When the connecting column 12 moves, it drives the limiting slider 15 to move along the shifting groove 14, which can improve the stability and smoothness of the movement of the connecting column 12, and the moving distance of the connecting column 12 can be limited by the limiting slider 15, so as to prevent the connecting column 12 from being separated from the slide cavity 11, or the connecting column 12 from being over-extruded and affecting the reset member 13.

[0076] In this embodiment, preferably, please refer to FIG. Figure 2-4 , and also includes a connecting shaft 16 and a transmission component 17 rotatably arranged on the support plate 2, the bottom of the connecting shaft 16 is connected to the camera 3, and the transmission component 17 is used to drive the connecting shaft 16 to rotate.

And when the drone body 1 moves back from the inside of the pipeline, the camera 3 is rotated to the rearward moving position, which can facilitate the observation and operation of the staff and facilitate the removal of the drone body 1.

Figure 3-4 The transmission component 17 includes a second driving member 171 disposed on the support plate 2, a first gear 172 is disposed at the output end of the second driving member 171, and a second gear 173 meshing with the first gear 172 is disposed at the upper end of the connecting shaft 16. The second driving member 171 in the present application can be a servo motor, and starting the second driving member 171 will drive the first gear 172 to rotate, and the first gear 172 will drive the second gear 173 and the connecting shaft 16 to rotate.

[0078] In this embodiment, preferably, please refer to FIG. Fig.10The wings of the drone body 1 are all equipped with protective frames 18. The protective frames 18 can protect the wings of the drone body 1, greatly reducing the collision between the wings of the drone body 1 and objects such as impurities on the inner wall of the pipeline, effectively improving its service life, and the protective frames 18 can be disassembled and assembled for easy movement and storage.
