Description

Technical Field

[0001] The invention relates to the technical field of pipeline robots, and in particular to an all-terrain pipeline detection robot with a new structure. Background Art

[0002] With the acceleration of urbanization and industrialization, various pipeline systems such as water supply, gas, and drainage are spread throughout the city's underground. Their safe and stable operation is directly related to residents' lives and economic development. However, traditional manual inspection and maintenance methods are inefficient, costly, and risky. The emergence of pipeline robots provides a revolutionary solution for pipeline inspection and maintenance. They can penetrate into complex and difficult-to-reach pipelines, and use the sensors and operating machinery they carry to perform precise inspection and maintenance operations, greatly improving efficiency and safety.

[0003] A pipeline robot is an integrated system of machinery, electricity and instrumentation that can automatically walk along the inside or outside of a small pipeline, carry one or more sensors and operating machinery, and perform a series of pipeline operations under remote control by staff or automatic control by a computer.

[0004] Pipeline robots often face challenges in complex environments when performing cleaning and maintenance tasks. Traditional pipeline robots cannot effectively cross obstacles such as silt and garbage in pipelines, which causes jams and prevents them from operating normally. Current pipeline robots are not flexible enough during movement and have difficulty operating normally in areas with many turns in the pipeline. In addition, as pipeline problems become increasingly complex, pipeline robots also need to be equipped with more modules to meet actual engineering needs. Current underwater pipeline robots have a simple structure and cannot reasonably carry infrared scanning, sonar and other modules. In response to these problems, this technology refers to the structure of the spider robot and increases the functionality of the pipeline robot by adding and improving the mechanical structure, allowing the pipeline robot to operate normally in a more complex pipeline environment. Summary of the invention

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] Please refer to Figure 1-2 , the specific implementation of a new type of all-terrain pipeline inspection robot is as follows:

[0037] The present invention relates to a novel all-terrain pipeline inspection robot, which has a high degree of flexibility and modular design and is suitable for inspection tasks in various complex pipeline environments. The specific structure and function implementation of the robot will be described in detail below.

[0038] First, the robot body 1 is the core part of the entire detection robot, which carries all functional modules and power equipment. The robot body 1 is made of high-strength lightweight materials to ensure sufficient structural strength and weight control. At the top of the robot body 1, a rear-end mechanical arm 8 is provided, which can be connected to other functional modules to meet the needs of different detection tasks.

[0039] Reference Figure 6At the front end of the robot body 1, front manipulator arms 5 are symmetrically arranged. The two manipulator arms are connected to the robot body 1 through a swing bar 19, and the swing bar 19 can rotate around its fixed axis to achieve the folding and extension of the manipulator arms. At the end of the swing bar 19, a rocker arm 20 is connected, and a plurality of piston cylinders 17 are arranged at the side ends of the rocker arm 20. These piston cylinders 17 can achieve the axial movement of the rocker arm 20 and the telescopic movement of the manipulator fingers 18 by advancing and contracting. The manipulator fingers 18 are used to grab obstacles or detect samples in the pipeline, and they can be replaced with other functional modules according to actual needs.

[0040] Reference Figure 1 , Figure 4 and Figure 8 In order to enhance the robot's obstacle-crossing ability and flexibility, a main power thruster 4 is symmetrically arranged at the side end of the robot body 1. The main power thruster 4 is the main power source of the robot, and is connected to the robot body 1 through a mechanical arm connection structure 3. The mechanical arm connection structure 3 includes a steering gear 12 and a steering plate 13 connected to the robot body 1. The steering gear 12 can realize the folding, extension and rotation of the mechanical arm connection structure 3 by driving the rotation of the steering plate 13. This design allows the main power thruster 4 to be flexibly adjusted according to the shape and size of the pipeline to adapt to different detection environments.

[0041] The specific structure of the main power thruster 4 includes a thruster steel frame 25 connected to the end of the robot arm connection structure 3. The thruster steel frame 25 is made of high-strength steel to ensure sufficient support strength and stability. At the front end and the end of the thruster steel frame 25, a front end constraint 26 and an end hinge constraint 24 are respectively provided. These two constraint structures are used to fix and support the main thruster motor 27 so that it can operate stably. The main thruster motor 27 is the core component of the main power thruster, which provides driving force to move the robot forward. Between the two main thruster motors 27, a motion spiral 23 is provided. The motion spiral 23 generates thrust through rotation, which combines with the driving force of the main thruster motor 27 to jointly push the robot forward.

[0042] Reference Figure 5 In order to further improve the flexibility and obstacle-crossing ability of the robot, an auxiliary screw propeller 2 is symmetrically arranged at the tail end of the robot body 1. The auxiliary screw propeller 2 includes an auxiliary propulsion motor 16, and its output end is connected to the turbine 14. An auxiliary propeller housing 15 is arranged outside the turbine 14 to protect the turbine 14 and guide the water flow. The auxiliary propulsion motor 16 generates thrust to help the robot move forward by driving the rotation of the turbine 14. At the same time, the auxiliary screw propeller 2 can also be folded, stretched, and rotated around an axis to adapt to different pipeline environments.

[0043] Reference Figure 3Inside the robot body 1, a battery 10 and a circuit board 11 are arranged. The battery 10 provides power support for the robot, and the circuit board 11 is responsible for controlling the various functions and movements of the robot. In order to enhance the perception ability of the robot, a sonar 9 is arranged at the bottom of the robot body 1. The sonar 9 can sense the pipeline environment and obstacle information around the robot by emitting and receiving sound waves, providing an important reference for the robot's navigation and obstacle avoidance.

[0044] In addition, a lighting lamp 6 and a high-definition camera mounting frame 7 are also provided at the front end of the robot body 1. The lighting lamp 6 is used to illuminate the inside of the pipeline to improve the visibility of the robot. The high-definition camera mounting frame 7 is used to install a high-definition camera to capture image information inside the pipeline. Such image information can be sent to the remote control center by wireless transmission for real-time monitoring and analysis by operators.

[0045] In the specific implementation, firstly, according to the shape and size of the pipeline, by adjusting the angle and position of the mechanical arm connection structure 3 and the main power propeller 4, the robot can adapt to different pipeline environments. Then, the main power propeller 4 and the auxiliary screw propeller 2 are started to make the robot start to move forward. During the process of moving forward, the sonar 9 continuously senses the surrounding pipeline environment and obstacle information, and transmits this information to the circuit board 11 for processing. According to this information, the operator can adjust the movement trajectory and speed of the robot through the remote control center to ensure that the robot can complete the detection task safely and accurately.

[0046] When the robot encounters an obstacle, it can grasp or bypass the obstacle by adjusting the posture of the front mechanical arm 5 and the telescopic movement of the mechanical finger 18. At the same time, the coupling power of the main power propeller 4 and the auxiliary screw propeller 2 can also help the robot achieve more complex movements, such as climbing, descending, turning, etc. These movement modes can greatly improve the robot's obstacle-crossing ability and flexibility.

[0047] Reference Figure 7 In addition, the external mounting module rack reserved by the rear-end robot arm 8 can also be added with various functional modules, such as sensors, detection instruments, etc. These functional modules can realize vertical movement and position adjustment through the linkage of the motion lever 21 and the piston cylinder 17. This design allows the robot to quickly replace and install corresponding functional modules according to different detection task requirements, thereby improving detection efficiency and accuracy.

[0048] In a specific embodiment, it is assumed that a circular pipe with a diameter of 500 mm needs to be detected. First, the main propeller 4 and the auxiliary propeller 2 of the robot are adjusted to a suitable angle and position so that they can adapt to the diameter and shape of the pipe. Then, the robot is started and moved forward. During the moving process, the sonar 9 continuously senses the obstacle information inside the pipe and transmits this information to the circuit board 11 for processing. The operator can adjust the movement trajectory and speed of the robot through the remote control center based on this information.

[0049] When the robot encounters obstacles in the pipeline, such as protruding pipe joints or sediments, the operator can grasp or bypass these obstacles by adjusting the posture of the front robot arm 5 and the telescopic movement of the robot finger 18. At the same time, the coupling power of the main power propeller 4 and the auxiliary screw propeller 2 can also help the robot achieve a more flexible movement mode, such as bypassing obstacles or changing the direction of movement.

[0050] During the inspection process, the high-definition camera can capture the image information inside the pipeline and send this information to the remote control center via wireless transmission. The operator can monitor and analyze this image information in real time to understand the condition and problems inside the pipeline. If further inspection or sampling analysis is required, the corresponding functional modules can be added through the external installation module rack reserved by the rear-end robot arm 8.

[0051] In addition, the pipeline inspection robot of the present invention also has high reliability and stability. The robot body 1 is made of high-strength lightweight materials, with sufficient structural strength and weight control. At the same time, the design of the main power propeller 4 and the auxiliary screw propeller 2 also fully considers the complexity and uncertainty factors of the pipeline environment, such as water flow, sediment, etc. These designs enable the robot to operate stably and complete the inspection task in various harsh environments.

[0052] In addition, the pipeline inspection robot of the present invention is also highly scalable and customizable. By replacing different functional modules and adjusting the structural parameters of the robot, the requirements of different pipeline environments and inspection tasks can be met. For example, for pipelines of different diameters and shapes, the angles and positions of the main power propeller 4 and the auxiliary screw propeller 2 can be adjusted to adapt; for different inspection task requirements, corresponding functional modules can be added to achieve them. This design enables the robot to have a wide range of applications and flexible application scenarios.

[0053] In the specific implementation process, the following points should be noted:

[0054] Before the robot enters the pipeline, the pipeline needs to be initially cleaned and inspected to ensure that the robot can enter smoothly and operate stably. At the same time, the various functions and equipment of the robot need to be tested and calibrated to ensure their accuracy and reliability.

[0055] During the operation of the robot, its status and position information need to be monitored in real time, and adjustments and controls need to be made according to the actual situation. If the robot fails or has an abnormal situation, it needs to be stopped immediately for inspection and maintenance.

[0056] After completing the inspection task, the robot needs to be cleaned and maintained to extend its service life and maintain its stable performance. At the same time, the inspection data needs to be analyzed and processed to obtain accurate inspection results and recommended measures.

[0057] In summary, the novel all-terrain pipeline inspection robot of the present invention has the characteristics of high flexibility, reliability and scalability, and is suitable for inspection tasks in various complex pipeline environments. By adjusting the structural parameters of the robot and replacing different functional modules, the needs and application scenarios of different customers can be met. At the same time, the robot also has a high level of intelligence and automation, and can independently complete the inspection task and transmit the inspection data in real time to the remote control center for analysis and processing. Therefore, the present invention has broad application prospects and market value.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
