Description

Technical Field

[0001] This utility model relates to the field of inspection device technology, specifically an automated pipeline inspection device. Background Technology

[0002] Pipelines typically refer to pipeline systems or pipeline systems used to transport liquids, gases, or other substances. When using pipelines for long-distance transportation operations, the pipelines are laid over long distances and often pass through remote and inaccessible areas. Therefore, it is inefficient to inspect pipelines manually. As a result, drones are often used for pipeline inspection.

[0003] Existing technologies, such as patent document CN219120358U, disclose a pipeline inspection drone, including a drone body equipped with a GPS positioning module, a rotatable camera, a gas detection device, a marking device, and a controller installed inside the drone body. This patent uses the rotatable camera to allow operators to inspect gas pipelines by manipulating the drone. When the drone detects gas near the pipeline during inspection, the GPS positioning module sends the location information to the operator, enabling the operator to quickly reach the approximate leak location. Simultaneously, the marking device activates to mark the surface of the pipeline where gas was detected. This patented technology replaces manual inspection, saving time spent manually inspecting gas pipelines, improving work efficiency, and avoiding safety hazards associated with patrol personnel venturing into mountainous areas, thus ensuring personal safety.

[0004] The aforementioned and existing related technologies often have the following drawbacks: In practical applications, when inspecting pipelines in rainy or snowy weather, rain and snow easily adhere to the drone's lens, interfering with the footage captured by the drone and making it difficult for operators to identify the condition of the pipelines, thus reducing the drone's practicality; moreover, existing drones have a rigid metal shell, which is easily damaged when the drone lands directly on the ground. Therefore, we propose an automated pipeline inspection device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] An automated pipeline inspection device is provided in the embodiment, such as Figures 1 to 5 As shown, the device includes a drone body 1 equipped with a GPS positioning module. A camera 4 is fixedly mounted on the bottom of the drone body 1. The drone body 1 contains a controller and a gas detection device mounted on the drone body. The gas detection device, camera 4, and GPS positioning module inside the drone body 1 are electrically connected to the controller. The drone body 1 includes a square shell, with propellers 3 located at the four corners of the shell. Each propeller 3 is controlled by a motor 2, and the controller inside the drone body 1 controls the four motors 2 to work synchronously. This drone body 1 is prior art and requires no further detailed explanation. The automated pipeline inspection device in this embodiment, such as... Figure 1 As shown, a cleaning mechanism 7 is provided in front of the lens 5 of the camera 4, and four supports 6 are provided on the lower surface of the drone body 1. The four supports 6 are distributed at the four corners of the drone body 1 shell, and a buffer mechanism 8 is provided at the bottom of each support 6.

[0026] In the embodiments, such as Figures 1 to 4 As shown, the cleaning mechanism 7 includes a first electric push rod 701, which is fixedly connected to the camera 4. The first electric push rod 701 is vertically fixed to the top of the camera 4, and its output shaft is connected to a mounting frame 702 through a connecting plate. The mounting frame 702 is located in front of the camera lens and can be moved to the front of the lens 5 or above the camera 4 under the action of the first electric push rod 701. Multiple heating rods 703 are fixedly connected to the inner wall of the mounting frame 702 near the lens 5. Each heating rod 703 is covered with a rubber sleeve 704. Multiple water-absorbing wires 705 are fixedly connected to the arc surface of the rubber sleeve 704. When the mounting frame 702 moves to the front of the lens 5, the multiple water-absorbing wires 705 contact the surface of the lens 5. The first electric push rod 701 controls the mounting frame 702 to move up and down, and the water-absorbing wires 705 clean the water stains on the surface of the lens 5.

[0027] like Figure 2 and Figure 3As shown in the embodiment, the cleaning mechanism 7 further includes a collection box 708. A fixing block 706 is fixedly connected to the top surface of the camera 4 near the lens 5. A sliding rod 707 is slidably connected inside the fixing block 706. The collection box 708 is fixedly connected to one end of the sliding rod 707 near the lens 5. When the mounting frame 702 moves to a position higher than the camera 4, the collection box 708 is located directly below the mounting frame 702. A downwardly inclined slope is provided on the surface of the collection box 708 near the sliding rod 707. Pressure rods 709 are fixedly connected to both sides of the mounting frame 702. The pressure rods 709 are slidably connected to the inclined slope of the collection box 708. After the collection box 708 slides under the water-absorbing wire 705, it can collect the water droplets dripping from the surface of the water-absorbing wire 705, preventing the water droplets from falling back onto the surface of the lens 5. When the pressure rods 709 on both sides of the mounting frame 702 disengage from the collection box 708, the leaf spring 710 begins to extend. The slide rod 707 will use the tension of the leaf spring 710 to make the inclined surface of the collection box 708 contact the pressure rod 709 again, and make the collection box 708 return to its original position and slide under the water-absorbing wire 705. Multiple sponge blocks 711 are fixedly connected to the inner wall of the collection box 708. The sponge blocks 711 will absorb the water droplets again, preventing the water droplets from flowing out of the collection box 708.

[0028] like Figure 5 As shown, the buffer mechanism 8 in the embodiment includes a second electric actuator 81, which is fixedly connected to the bracket 6. A rack 82 is fixedly connected to the output end of the second electric actuator 81. A gear 83 is rotatably connected inside the bracket 6. The rack 82 meshes with the gear 83. An elastic plate 84 is fixedly connected to the arc surface of the gear 83. A connecting plate 85 is fixedly connected to the surface of the bracket 6. A clamping plate 86 is fixedly connected to the surface of the connecting plate 85. The clamping plate 86 is slidably connected to the rack 82. When the rack 82 slides along the surface of the clamping plate 86, the clamping plate 86 restricts the sliding path of the rack 82, allowing the rack 82 to make close contact with the gear 83.

[0029] The working process of this utility model is as follows: During pipeline inspection, the propeller 3 is rotated by the motor 2, which in turn causes the outer casing 1 to carry the camera 4 in flight. Then, the camera 4 can be used for automated inspection. During the inspection, when the lens 5 is covered by rain or snow, the output end of the first electric actuator 701 retracts. The output end of the first electric actuator 701 moves the mounting frame 702 downwards. The mounting frame 702 moves the pressure rod 709, which in turn presses the inclined surface of the collection box 708. The collection box 708 slides away from the fixed block 706. The sliding rod 707, aided by the sliding of the collection box 708, presses the leaf spring 710, putting it in a compressed state. The movement of the mounting frame 702 moves the heating rod 703, which in turn moves the rubber sleeve 704. The movement of the rubber sleeve 704 moves the water-absorbing wire 705. Then, the rubber sleeve 704 and the water-absorbing wire 705 come into contact with the lens 5. 4. The absorbent wire 705 wipes and absorbs water droplets from the surface of the lens 5. After cleaning, the output end of the first electric push rod 701 extends, and the mounting frame 702 slides upward. When the absorbent wire 705 disengages from the lens 5, the pressure rod 709 disengages from the collection box 708, and the leaf spring 710 extends. The sliding rod 707, with the help of the tension of the leaf spring 710, makes the inclined surface of the collection box 708 re-engage with the pressure rod 709, and the collection box 708... The device slides back to the bottom of the absorbent wire 705 to collect water droplets dripping from its surface, preventing them from falling back onto the lens 5. Simultaneously, the sponge block 711 absorbs the water droplets again, preventing them from flowing out of the collection box 708. Then, the heating rod 703 is activated, heating the rubber sleeve 704 and the absorbent wire 705 to quickly evaporate the moisture inside the absorbent wire 705, making it easier to clean the lens 5 with the absorbent wire 705 next time.

[0030] During the inspection process, the output end of the second electric actuator 81 is extended, and the retraction of the output end of the second electric actuator 81 causes the rack 82 to slide along the surface of the clamp 86. The clamp 86 restricts the sliding path of the rack 82, allowing the rack 82 to make close contact with the gear 83. The sliding of the rack 82 causes the gear 83 to rotate, and the rotation of the gear 83 causes the elastic plate 84 to rotate, thereby rotating the elastic plate 84 upward and retracting it, preventing the elastic plate 84 from hitting the pipe during the inspection, allowing the camera 4 to take pictures at a closer position to the pipe. When the drone lands, the output end of the second electric actuator 81 is retracted, at which time the elastic plate 84 will unfold. After the elastic plate 84 touches the ground, it can reduce the impact force between the bracket 6 and the ground, preventing damage to the outer shell 1.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
