[0002] Currently, natural gas venting pipes are an indispensable and crucial component in natural gas processing, storage, and transportation systems. Due to their long-term exposure to the atmosphere and the continuous harsh conditions of sunlight, high temperatures, and rain, the anti-corrosion coating on the surface of venting pipes gradually ages and peels off, leading to corrosion and rust on the metal base. To ensure the normal operation and service life of natural gas venting pipes, their anti-corrosion coating needs to be repaired regularly. However, the diverse structural forms of current natural gas venting pipes and the lack of unified standards present numerous challenges to anti-corrosion coating repair work.

[0003] At present, the repair of anti-corrosion layers generally adopts the manual high-altitude sandblasting method. On the one hand, the high-altitude working environment is complex, the construction efficiency is low and the difficulty is extremely high, and the construction personnel face high safety risks. On the other hand, the operation process is seriously affected by human factors, the continuity is difficult to guarantee, the repair quality is inconsistent, and it cannot consistently meet the actual project needs.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] This embodiment provides a high-altitude repair device for the anti-corrosion layer of a natural gas vent pipe, which reduces human intervention, improves safety, and enhances the repair quality and efficiency of the anti-corrosion layer.

[0038] like Figures 1-2 As shown, the high-altitude repair device for the anti-corrosion layer of the natural gas vent pipe mainly includes a flight mechanism 10 and an anti-corrosion layer repair mechanism. The anti-corrosion layer repair mechanism includes a storage tank 20, a pushing component, a spray gun 30, an adjusting component 40, a supply tank 50, and a hose 60. The storage tank 20 is detachably connected to the flight mechanism 10. The pushing component is located inside the storage tank 20, and one end of the spray gun 30 is placed inside the storage tank 20 and communicates with the pushing component. One end of the adjusting component 40 is movably connected to the outer wall of the storage tank 20, and the other end of the adjusting component 40 is connected to the spray gun 30. The adjusting component 40 is configured to adjust the position of the spray gun 30. The supply tank 50 is located on the ground and is used to hold rust-removing media or anti-corrosion paint. One end of the hose 60 is connected to the supply tank 50, and the other end of the hose 60 is connected to the pushing component.

[0039] Based on the above design, the flight mechanism 10 has the capability to precisely carry the anti-corrosion repair mechanism to the high-altitude working position of the natural gas vent pipe 100. The detachable connection design between the storage tank 20 and the flight mechanism 10 enhances flexible assembly, facilitating rapid equipment configuration according to actual task requirements. The flight mechanism 10 carries the anti-corrosion repair mechanism into the air, avoiding direct climbing of the natural gas vent pipe 100 by personnel, thereby reducing human intervention, lowering safety hazards, and improving safety. One end of the adjustment component 40 is movably connected to the outer wall of the storage tank 20, and the other end is connected to the spray gun 30. The adjustment component 40 allows for precise adjustment of the spray gun 30's position according to the actual shape, diameter, and structure of the natural gas vent pipe 100, enabling the spray gun 30 to approach the surface of the natural gas vent pipe 100 from all directions and multiple angles, improving the efficiency of anti-corrosion repair. The supply tank 50 is placed on the ground and is used to hold large quantities of rust-removing media or anti-corrosion paint. The hose 60 connects to the push assembly. The hose 60 possesses excellent flexibility, ensuring it doesn't affect the flight maneuverability of the flight mechanism 10 while continuously and stably supplying the storage tank 20 with rust-removing media or anti-corrosion paint throughout the repair process. This effectively solves the inefficiency problem caused by the limited capacity of the storage tank 20, requiring frequent interruptions to replace it, significantly improving the continuity of the repair work and increasing work efficiency. The push assembly continuously and stably provides rust-removing media or anti-corrosion paint, working in conjunction with the automated spray gun 30 to avoid the intermittent interruptions of manual spraying of rust-removing media or anti-corrosion paint, thus improving the repair quality and efficiency of the anti-corrosion layer.

[0040] It should be noted that in this embodiment, there are two anti-corrosion repair mechanisms. One mechanism has a supply tank 50 for holding rust-removing media (e.g., quartz sand), and the other mechanism has a supply tank 50 for holding anti-corrosion paint. The flight mechanism 10 takes off carrying the anti-corrosion repair mechanism containing the rust-removing media and performs sandblasting on the natural gas vent pipe 100 to remove surface oxidation, rust coatings, or contaminants. Then, the flight mechanism 10 returns to the ground carrying the anti-corrosion repair mechanism containing the rust-removing media. The operator replaces the repair mechanism with one containing anti-corrosion paint. Then, the flight mechanism 10 takes off again carrying the repair mechanism containing anti-corrosion paint and performs anti-corrosion paint spraying on the natural gas vent pipe 100.

[0041] In some alternative embodiments, the pushing component can be configured as a compressed air pump to draw in the quartz sand or anti-corrosion paint from the supply tank 50, and then use compressed air to generate an airflow to force the quartz sand or anti-corrosion paint from the storage tank 20 into the spray gun 30 along the pipeline for spraying. Alternatively, the pushing component can be configured as a diaphragm pushing pump, which uses the reciprocating movement of the diaphragm to create negative and positive pressures within the pump chamber, thereby drawing in and expelling quartz sand or anti-corrosion paint to achieve continuous media delivery. The pushing component can also be configured as a jet pump, which uses the negative pressure generated by a high-speed fluid (such as air) passing through a nozzle to draw in quartz sand or anti-corrosion paint and mix it with the fluid, using the kinetic energy of the fluid to propel the media forward.

[0042] like Figures 1-2 As shown, in this embodiment, the adjustment assembly 40 includes a universal joint ball head 41 and a telescopic rod 42. One end of the universal joint ball head 41 is connected to the storage tank 20, and the other end is connected to one end of the telescopic rod 42. The other end of the telescopic rod 42 is connected to the spray gun 30. The universal joint ball head 41 includes a ball head seat and a ball. The ball head seat is fixed to the storage tank 20, and the ball is embedded in the ball head seat and connected to the telescopic rod 42. The ball can rotate within the ball head seat. The flexibility of the ball's rotation within the ball head seat allows the spray gun 30 to rotate flexibly, covering all directions of the surface of the natural gas vent pipe 100 as much as possible, ensuring no blind spots in rust removal and painting operations. At the same time, the tight connection between the ball and the telescopic rod 42 ensures efficient force transmission, making the adjustment action of the spray gun 30 smoother and more stable, improving reliability and durability. The telescopic rod 42 allows for more flexible adjustment of the distance between the spray gun 30 and the surface of the natural gas vent pipe 100. The telescopic rod 42 can precisely control the distance between the spray gun 30 and the surface of the natural gas vent pipe 100, thereby achieving more precise rust removal and painting effects and further improving the repair quality.

[0043] In some alternative implementations, the telescopic rod 42 is an electric actuator or a hydraulic actuator.

[0044] like Figure 2 As shown, the high-altitude repair device for the anti-corrosion layer of the natural gas vent pipe in this embodiment also includes a flexible connector 21. One end of the flexible connector 21 is connected to the storage tank 20, and the other end is connected to the spray gun 30. The flexible connector 21 allows the spray gun 30 to rotate flexibly relative to the storage tank 20 when the adjusting component 40 adjusts the position of the spray gun 30, avoiding interference between the spray gun 30 and the storage tank 20. For example, the flexible connector 21 can be configured as a flexible silicone sleeve.

[0045] like Figure 2As shown, the flight mechanism 10 includes a drone 11 and a connecting frame 12. The connecting frame 12 is located below and connected to the drone 11, forming an accommodating space between the connecting frame 12 and the drone 11. The storage box 20 is disposed within this accommodating space. This design not only ensures the stable installation of the storage box 20 but also makes full use of the spatial layout of the drone 11, optimizing the overall structure. The drone 11, as a flight platform, possesses flexible flight capabilities, enabling it to quickly and accurately carry the anti-corrosion layer repair mechanism to a high-altitude working position.

[0046] Furthermore, in this embodiment, the storage box 20 is provided with a connecting plate 22 at its bottom, and the connecting plate 22 is detachably connected to the connecting frame 12. For example, it can be detachably connected by bolts or by snap-fit, thereby facilitating the disassembly and replacement of the anti-corrosion layer repair mechanism.

[0047] For example, four connecting plates 22 are provided, and the four connecting plates 22 are located at the four corners of the bottom of the storage box 20, which improves the stability and reliability of the storage box 20 and reduces stress concentration.

[0048] Furthermore, in this embodiment, the connecting frame 12 includes a first connecting rod 121 and a second connecting rod 122. The first connecting rod 121 is connected to the connecting plate 22, and one end of the second connecting rod 122 is connected to the middle of the first connecting rod 121, while the other end is connected to the drone 11. This effectively disperses the pressure of the storage box 20 and its internal medium on the connecting frame 12, enhancing its load-bearing capacity and stability. Simultaneously, this layout also helps to better distribute the load on the drone 11, ensuring the balance and flight attitude stability of the drone 11 during flight, and guaranteeing the smooth progress of the repair operation.

[0049] like Figure 2As shown, the drone 11 in this embodiment includes a power system 15, a flight control system 16, an adjustable camera 13, and a propeller 14. The power system 15 includes a stepper motor, an electronic speed controller (ESC), and a battery. The stepper motor is connected to the propeller 14 via a transmission connection. The ESC is used to adjust the speed of the stepper motor, and the battery powers the stepper motor and ESC. The flight control system 16 is electrically connected to the stepper motor of the power system 15 and is used to control the flight attitude and trajectory of the propeller 14, ensuring that the drone 11 can stably fly to the working position of the natural gas vent pipe 100 according to a preset route and attitude, and maintain a stable flight state throughout the repair process. The adjustable camera 13 is signal-connected to the flight control system 16 and is used to collect the position data of the natural gas vent pipe 100 in real time and transmit it to the flight control system 16. Based on this real-time data, the flight control system 16 fine-tunes the flight attitude of the drone 11 to ensure that the spray gun 30 can accurately align with the surface of the natural gas vent pipe 100, providing precise positioning support for subsequent rust removal and painting repair operations. Through the efficient operation of the power system 15, the precise control of the flight control system 16, and the real-time feedback monitoring of the adjustment camera 13, the three work closely together to form a highly stable, precise, and flexible flight control platform.

[0050] Specifically, in this embodiment, two adjustment components 40 are configured, and the two adjustment components 40 are symmetrically arranged about the plane containing the axis of the spray gun 30. The flight control system 16 is electrically connected to the adjustment components 40. When the flight mechanism 10 arrives at the working position of the natural gas vent pipe 100, the adjustment camera 13 will collect image information of the surface of the natural gas vent pipe 100 in real time and transmit this data to the flight control system 16. The flight control system 16 has preset operating parameters, such as the ideal distance between the spray gun 30 and the surface of the natural gas vent pipe 100, and the range of spray angles. The flight control system 16 compares and analyzes the real-time images with the preset parameters to determine whether the current position of the spray gun 30 meets the operating requirements.

[0051] If the position of the spray gun 30 needs adjustment, the flight control system 16 will generate a corresponding control signal based on the analysis results. For the adjustment component 40 of the telescopic rod 42, which is an electric push rod, the flight control system 16 converts the control signal into an electrical signal and transmits it to the drive motor of the electric push rod. The drive motor starts according to the signal command, driving the lead screw or nut to rotate, causing the electric push rod to extend or retract, thereby changing the position of the spray gun 30 in the vertical direction. By changing the extension or retraction distance of the two electric push rods, the position of the spray gun 30 in the horizontal direction is changed (i.e., the spray gun 30 turns left or right). The flight control system 16 continuously monitors the image fed back by the adjustment camera 13, and evaluates in real time whether the position of the spray gun 30 has reached the preset ideal state. Once it has, it stops sending control signals to the electric push rod.

[0052] Throughout the adjustment process, the flight control system 16 continuously receives image information from the adjustment camera 13 and evaluates in real time whether the position and attitude of the spray gun 30 meet the operational requirements. If there is any deviation, the flight control system 16 will continuously adjust the control signal until the spray gun 30 is precisely and stably aligned with the optimal operating position on the surface of the natural gas vent pipe 100.

[0053] The working process of the high-altitude repair device for the anti-corrosion layer of the natural gas vent pipe in this embodiment is as follows:

[0054] (I) Preliminary Preparations

[0055] Equipment Assembly and Inspection: Prepare two sets of anti-corrosion repair mechanisms. One set contains quartz sand in storage box 20, and the other set contains anti-corrosion paint in storage box 20. Conduct a comprehensive inspection of the flight mechanism 10 and the anti-corrosion repair mechanism to ensure that all components are securely connected. Check that the power system 15, flight control system 16, and adjustment camera 13 of the flight mechanism 10 are functioning normally, that the spray gun 30 is unobstructed, that the adjustment component 40 is flexible and reliable, and that the hose 60 is tightly connected without leakage.

[0056] Operation planning and parameter setting: A detailed operation plan is formulated based on factors such as the location, height, shape, corrosion level, and surrounding environment of the natural gas vent pipe 100. Relevant parameters, including flight altitude, speed, working pressure of the spray gun 30, and flow rates of quartz sand and anti-corrosion paint, are input into the control terminals of the flight mechanism 10 and the anti-corrosion layer repair mechanism to ensure precise control of the operation process.

[0057] (II) Sandblasting and Rust Removal Stage

[0058] Flight to work location: The operator starts the flight mechanism 10 via the control terminal (remote control handle), carrying the anti-corrosion repair mechanism containing quartz sand. The flight control system 16 automatically controls the flight attitude and trajectory according to preset parameters, adjusts the camera 13 to monitor the surrounding environment in real time and provide feedback information, assisting the flight control system 16 in precise navigation, so that the flight mechanism 10 flies smoothly and accurately to the work location of the natural gas vent pipe 100.

[0059] Sandblasting and rust removal operation: After the flight mechanism 10 arrives at the working position of the natural gas vent pipe 100, the flight control system 16 controls the push component to start working, pushing the quartz sand from the storage tank 20 to the spray gun 30. At the same time, the adjustment component 40 flexibly adjusts the position and angle of the spray gun 30 according to the actual situation of the surface of the natural gas vent pipe 100 and the preset parameters, so that the spray gun 30 maintains a suitable distance and optimal spray angle from the surface of the natural gas vent pipe 100. Under the action of high-pressure fluid, the spray gun 30 sprays the quartz sand at high speed onto the surface of the natural gas vent pipe 100, using the impact force of the quartz sand to remove rust, old paint, oxide scale and other impurities from the surface until the metal is exposed. During this process, the flight control system 16 adjusts the flight attitude in real time according to the information fed back by the adjustment camera 13 to ensure the stable operation of the anti-corrosion layer repair mechanism, and the spray gun 30 can evenly and comprehensively cover the surface of the natural gas vent pipe 100, achieving an efficient and thorough rust removal effect.

[0060] (III) Equipment Replacement Phase

[0061] Return to Ground: After the sandblasting and rust removal operation is completed, the flight control system 16 controls the flight mechanism 10, carrying the anti-corrosion repair mechanism, to smoothly return to the designated ground position. Operators wait on the ground for the flight mechanism 10 to land and take necessary safety precautions to ensure the safety of equipment and personnel.

[0062] Equipment Replacement: After the flight mechanism 10 lands, the operator quickly removes the anti-corrosion repair mechanism containing quartz sand from the flight mechanism 10 and places it properly. Then, the anti-corrosion repair mechanism containing anti-corrosion paint is installed back onto the flight mechanism 10, ensuring a secure and reliable connection and that all components are functioning normally.

[0063] (iv) Painting Stage

[0064] Flight to work position: The operator restarts the flight mechanism 10 via the control terminal (remote control handle), and the anti-corrosion repair mechanism carrying the anti-corrosion paint takes off. The flight control system 16 automatically controls the flight mechanism 10 to fly to the work position of the natural gas vent pipe 100 according to preset parameters and previously recorded work information, in preparation for painting work.

[0065] Painting Operation: After the flight mechanism 10 arrives at the working position of the natural gas vent pipe 100, the flight control system 16 controls the push component to push the anti-corrosion paint from the storage tank 20 to the spray gun 30. The adjustment component 40 flexibly adjusts the position and angle of the spray gun 30 according to the surface condition of the natural gas vent pipe 100 and preset parameters, so that the spray gun 30 maintains a suitable distance and optimal spraying angle from the surface of the natural gas vent pipe 100. Under a certain pressure, the spray gun 30 evenly sprays the anti-corrosion paint onto the surface of the rust-removed natural gas vent pipe 100, forming a uniform, continuous, and dense anti-corrosion paint film. During the painting process, the flight control system 16 monitors the flight attitude in real time and makes fine adjustments as needed to ensure that the anti-corrosion paint is sprayed evenly, without omissions or drips, and to guarantee the quality of anti-corrosion. At the same time, the thickness and number of anti-corrosion paint layers can be controlled according to the material, design requirements, and environmental factors of the natural gas vent pipe 100 to meet different anti-corrosion needs.

[0066] (V) Completion and Conclusion of the Work

[0067] Evacuation and Recovery: After the painting operation is completed, the flight control system 16 controls the flight mechanism 10, carrying the anti-corrosion repair mechanism, to smoothly evacuate the area of ​​the natural gas vent pipe 100 and return to the designated recovery point on the ground.
