Description

Technical Field

[0001] This invention relates to the field of robot line inspection technology, specifically to a communication engineering installation line inspection robot. Background Technology

[0002] A communication engineering installation line inspection robot is disclosed. The core value of this inspection robot is to replace manual labor in complex, dangerous, and inefficient scenarios to complete line inspection. The robot can walk along the line by means of wheel, track, or crawling mechanism, adapt to the complex terrain around the communication base station, flexibly deal with height differences and small obstacles, and integrate a multi-dimensional perception system such as high-definition zoom camera and infrared thermal imaging to accurately identify potential hazards such as loose lines and line connections.

[0003] However, existing technologies still have the following drawbacks in practical applications:

[0004] 1. In existing technologies, inspection robot lenses are susceptible to contamination and fogging. On the one hand, outdoor inspection scenarios are complex, with rainwater, dust, and other pollutants adhering irregularly. Lens protection designs rely solely on passive protection, such as simple dust covers and basic anti-fog coatings, lacking active cleaning interventions and failing to remove dynamically adhering pollutants in real time. On the other hand, in high-temperature and high-humidity environments, there is a significant temperature difference between the lens and the outside air. When the air humidity is saturated, water vapor quickly condenses into small water droplets on the cooler lens surface. Although anti-fog coatings can temporarily change the surface tension and delay fogging, the hydrophilic and hydrophobic properties of the coating material will decay over time and with temperature changes. Furthermore, during continuous operation, the heat exchange between the lens and the environment constantly disrupts the temperature balance, leading to anti-fogging failure.

[0005] During inspections, lens contamination and fogging can directly damage image quality, making it impossible to identify cable defects such as minor cracks and abnormal connectors. This causes the robot to "miss inspections," shifting the cost of manual inspection to subsequent maintenance and potentially leading to communication failures. From an efficiency perspective, blurred images require frequent manual intervention to clean the lens and restart the equipment, disrupting the preset inspection rhythm, extending the time for each task, and reducing overall inspection coverage efficiency. More importantly, the risk of missed inspections can accumulate into communication line failures, threatening the stability of the power grid and communication networks, and even causing safety accidents, thus weakening the core value of inspection robots in replacing manual labor.

[0006] 2. Existing inspection robots have significant shortcomings in lens protection and anti-light interference. First, when not in use, the lens is only protected by a fixed outer shell, with assembly gaps between the shell and the lens and no sealing structure, allowing dust and moisture to easily enter through the gaps. When in use, there is no effective light-shielding structure around the lens, only a fixed short light hood with a fixed angle and limited coverage. Side backlight can enter through the side gaps, and stray light can enter from all directions, thus failing to intercept light from multiple directions. These rays superimpose with the main light path inside the lens, destroying the image contrast.

[0007] The superposition of ambient light and main light path will cause a serious deterioration in image quality, resulting in glare, light spots and local overexposure in the image. The edge details and minor defects of the cable are obscured and difficult to distinguish clearly. As a result, the subsequent detection algorithm cannot accurately identify problems such as broken strands of conductors and damaged insulators, which greatly increases the risk of missed detection. At the same time, it will also increase the workload and cost of manual re-inspection and affect the efficiency of inspection.

[0008] Therefore, in view of this, the present invention proposes a communication engineering installation line inspection robot to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0009] To address the aforementioned technical problems, this invention provides a communication engineering installation line inspection robot to solve the technical problems mentioned in the background section.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a communication engineering installation line inspection robot, comprising an inspection carrier, a control module mounted on top of the inspection carrier, an inspection module mounted on top of the control module, a detection pre-processing mechanism provided on the side of the inspection module, the detection pre-processing mechanism comprising an outer tube, an assembly plate mounted inside the outer tube, and a connecting pipe evenly mounted on the output end of the outer tube; the outer tube and the inspection module are located on the same axis, and when the inspection module is in use, the outer tube will intermittently push gas to the position of the inspection module through the reciprocating movement of the internal assembly plate; the generated gas will be cooled when passing outside the inspection module, and will be purged when reaching the end position of the inspection module.

[0011] Furthermore, the control module includes a main control chip and a motion controller. The main control chip is responsible for overall system control and data processing, while the motion controller is used to precisely control the robot's motion behavior, including speed, direction, and position. The inspection module includes a protective shell and an inspection camera. The protective shell is in the shape of a regular hexagon.

[0012] Furthermore, an electric actuator shaft is installed inside the outer cylinder. The electric actuator shaft has a multi-section telescopic structure. The fixed end of the electric actuator shaft is fixedly connected to the inner wall of the outer cylinder, and the outer wall of the moving end is fixedly connected to the assembly plate. The electric actuator shaft is controlled by a control module and is initially in a retracted state.

[0013] Furthermore, the surface of the assembly plate is symmetrically connected to a limit rod through which a sliding connection is made. Both ends of the limit rod are fixedly connected to the inner wall of the outer cylinder. A one-way valve is installed inside the output end of the outer cylinder. Initially, the one-way valve is in a closed state.

[0014] Furthermore, a bearing base is sleeved on the side wall of the output end of the external cylinder, and the external cylinder and the connecting pipe are kept in communication through the bearing base. The connecting pipe is located between the protective shell of the inspection module and the inspection camera. The connecting pipe is slidably connected to the inspection module and runs through the front and rear sides of the inspection module. The connecting pipe is located at each diagonal position inside the protective shell, and notches are opened through the connecting pipe at the positions corresponding to the inspection cameras.

[0015] Furthermore, a centering ring is installed at the end of the connecting pipe away from the bearing base, and a drain pipe is evenly installed between the connecting pipe and the centering ring. The connecting pipe, the drain pipe, and the centering ring are connected. The drain pipe is funnel-shaped, and the centering ring is located outside the end of the inspection camera.

[0016] Furthermore, the centering ring cylinder is uniformly connected with nozzles, the nozzles are generally arc-shaped, and there is a groove between every two adjacent nozzles.

[0017] Furthermore, the side of the inspection module is provided with a detection auxiliary mechanism, which includes a first disc sleeved on the outside of the inspection module, a second disc fixedly connected to the side wall of the first disc, and a light shield fixedly connected to the side wall of the second disc. The light shield is corrugated in shape and is located in the upper half of the second disc.

[0018] Furthermore, a rotating ring is rotatably connected inside the first set of discs, and an electric rotating shaft is fixedly connected to the surface of the rotating ring. The end of the electric rotating shaft away from the rotating ring is installed inside the control module, and the electric rotating shaft is controlled by the control module.

[0019] Furthermore, the surface of the rotating ring is uniformly perforated with curved grooves, and each curved groove is slidably connected to a linkage plate. A positioning ring is installed on the side of the linkage plate away from the curved groove. Each positioning ring is provided with a right-angle groove near the linkage plate. The linkage plate and the positioning ring are slidably connected through the right-angle grooves, and the positioning ring is fixedly connected to the inner wall of the second disc.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) This device achieves intermittent blowing of the inspection camera by the reciprocating movement of the internal assembly plate of the outer tube. It can specifically solve the problems of lens contamination and fogging in the prior art. When the gas is gathered into the centering ring tube through the diversion tube and then sprayed out through the arc-shaped nozzle, the resulting ring airflow can fully cover the surface of the camera, remove rainwater, dust and other dynamically attached pollutants in time, and prevent them from forming obstructions or light spots on the lens, ensuring that the subtle defects of the cable edge are always clearly visible. Compared with the prior art, this active cleaning mechanism can respond to the pollution of the complex outdoor environment in real time, reduce the risk of missed detection due to the accumulation of pollutants, and at the same time, the barrier formed by the airflow can reduce the probability of external pollutants re-attaching. There is no need for frequent manual intervention in cleaning, ensuring the continuity of the inspection work and reducing the cost of manual inspection.

[0022] During actual purging, the gas generated at the nozzles undergoes convection, forming a dynamic circulation on the camera surface. This enhances the ability to remove stubborn contaminants and avoids cleaning dead spots caused by uneven airflow in a single direction, ensuring that every part of the lens is thoroughly cleaned. At the same time, the air curtain formed by the convection can more effectively block the intrusion of external moisture and dust, reducing the probability of lens fogging and secondary contamination. Especially in rainy or dusty environments, this structure allows the airflow to continuously maintain the cleanliness of the lens surface, ensuring that image clarity is not affected. The grooves provide a buffer space for the convective airflow, preventing the airflow from adjacent nozzles from interfering with each other and forming turbulence. This ensures the stability of the airflow and guides some gas to flow along the lens edge, enhancing the cleaning of contaminants in crevices.

[0023] Most importantly, as the airflow flows along the connecting pipe, it exchanges heat thoroughly with the protective shell and camera through the pipe wall. Combined with the direct blowing of the notch to the side of the lens, it can quickly remove the heat generated by the equipment, maintain the camera at a stable operating temperature, and reduce the temperature difference between the lens and the outside air. This not only avoids the decrease in imaging accuracy or equipment damage caused by overheating, but also slows down the degradation of the anti-fog coating performance, reduces fogging caused by the disruption of temperature balance during continuous operation, ensures stable imaging quality, reduces the need for manual secondary inspections, improves overall inspection efficiency, and reduces subsequent maintenance costs.

[0024] (2) This device effectively solves the problem of light interference in the prior art by using the light-shielding design of the detection auxiliary mechanism. When the inspection module is started, the linkage plate drives the second set of disks to form a stable distance with the first set of disks. The corrugated light shield fixed on the upper half of the second set of disks can cover the upper and side upper areas of the lens. The corrugated structure weakens the direct intensity of side backlight and stray light through surface diffuse reflection, reducing the probability of light directly entering the lens. At the same time, it uses its own shape to form a physical shield to avoid the image overexposure or contrast reduction caused by the superposition of strong light and the main light path, ensuring that the details and minor defects of the cable edge are clearly distinguishable. Compared with the problem of limited coverage of the fixed short light shield in the prior art, it significantly improves the imaging quality in complex lighting environments.

[0025] The detection auxiliary mechanism can flexibly switch between use and non-use states, balancing protection and convenience. When not in use, the linkage plate retracts, and the second set of discs fits tightly with the first set of discs, making the entire mechanism compact and reducing the impact on robot movement and storage, while also preventing damage to the light-shielding structure from external collisions. When in use, the linkage plate expands, creating a gap between the second set of discs and the first set of discs, ensuring that the light-shielding cover is in an effective light-shielding position. This design overcomes the shortcomings of insufficient protection of the lens fixing shell and the lack of a shrinkable sealing structure in the existing technology. It enhances the protection of the structure around the lens without affecting its use and reduces the possibility of dust and moisture intruding through gaps. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] It should be noted that the structure and working principle of the above-mentioned inspection carrier 1, control module 11, inspection module 12 and other devices are existing technologies and will not be described in detail here.

[0041] Example 1

[0042] Please refer to Figure 1 - Figure 9 As shown, a communication engineering installation line inspection robot includes an inspection carrier 1, a control module 11 mounted on top of the inspection carrier 1, an inspection module 12 mounted on top of the control module 11, and a detection pre-processing mechanism 2 provided on the side of the inspection module 12. The detection pre-processing mechanism 2 includes an outer tube 21, an assembly plate 23 installed inside the outer tube 21, and a connecting pipe 27 evenly installed at the output end of the outer tube 21. The outer tube 21 and the inspection module 12 are located on the same axis. When the inspection module 12 is in use, the outer tube 21 will intermittently push gas to the position of the inspection module 12 through the reciprocating movement of the internal assembly plate 23. The generated gas will be cooled when passing outside the inspection module 12 and will be purged when it reaches the end position of the inspection module 12.

[0043] It should be noted that the control module 11 includes a main control chip and a motion controller. The main control chip is responsible for the overall system control and data processing, while the motion controller is used to precisely control the robot's motion behavior, including speed, direction, and position. The inspection module 12 includes a protective shell and an inspection camera. The protective shell is in the shape of a regular hexagon.

[0044] Please refer to Figure 1 - Figure 9 As shown, an electric actuator shaft 22 is installed inside the outer cylinder 21. The electric actuator shaft 22 has a multi-section telescopic structure. The fixed end of the electric actuator shaft 22 is fixedly connected to the inner wall of the outer cylinder 21, and the outer wall of the moving end is fixedly connected to the assembly plate 23. The electric actuator shaft 22 is controlled by the control module 11 and is initially in a retracted state. Limit rods 24 are symmetrically slidably connected through the surface of the assembly plate 23. Both ends of the limit rods 24 are fixedly connected to the inner wall of the outer cylinder 21. A one-way valve 25 is installed inside the output end of the outer cylinder 21. The one-way valve 25 is initially in a closed state. A bearing base 26 is sleeved on the side wall of the output end of the outer cylinder 21. The outer cylinder 21 and the connecting pipe 27 are connected through the bearing base 26. The connecting pipe 27 is located between the protective shell of the inspection module 12 and the inspection... Between the cameras, the connecting pipe 27 is slidably connected to the inspection module 12 and runs through the front and rear sides of the inspection module 12. The connecting pipe 27 is located at each diagonal position inside the protective shell, and notches 28 are opened through the connecting pipe 27 at the positions corresponding to the inspection cameras. A centering ring cylinder 210 is installed at the end of the connecting pipe 27 away from the bearing base 26. Drainage pipes 29 are evenly installed between the connecting pipe 27 and the centering ring cylinder 210. The connecting pipe 27, drainage pipes 29, and centering ring cylinder 210 are kept connected. The drainage pipe 29 is funnel-shaped, and the centering ring cylinder 210 is located outside the end of the inspection camera. Nozzles 211 are evenly connected inside the centering ring cylinder 210. The nozzles 211 are arc-shaped, and there is a groove between every two adjacent nozzles 211.

[0045] Specifically, when the inspection robot enters the inspection operation stage, the control module 11 sends a start signal to the detection pre-processing mechanism 2. The electric push shaft 22 inside the outer cylinder 21 begins to reciprocate at a preset frequency. Initially, the electric push shaft 22 is in a fully retracted state, with its fixed end firmly connected to the inner wall of the outer cylinder 21 and its moving end fixed to the assembly plate 23. Therefore, when the electric push shaft 22 receives an extension command, its multi-section structure extends outwards sequentially, pushing the assembly plate 23 along the limit rod 24 towards the outer cylinder 21. The output end slides smoothly. As the assembly plate 23 moves, the enclosed space inside the outer cylinder 21 continuously shrinks, and the air pressure gradually increases. When the air pressure reaches the opening threshold of the one-way valve 25, the one-way valve 25 automatically opens, and the gas flows into the bearing base 26 through the output end of the outer cylinder 21. The bearing base 26 acts as a diversion hub, evenly distributing the gas to multiple sets of connecting pipes 27. These pipes run through the front and rear sides of the inspection module 12 and are located at diagonal positions inside the protective shell, forming an airflow channel surrounding the inspection camera.

[0046] When the gas flows within the connecting pipe 27, it exchanges heat with the protective shell and the inspection camera through the pipe wall, quickly carrying away the heat generated by the inspection camera during operation. Especially in high-temperature environments, the continuous airflow can effectively reduce the operating temperature of the camera, preventing overheating from causing a decrease in imaging accuracy or equipment damage. On the other hand, some of the gas is blown directly to the side of the camera through the notch 28 opened in the connecting pipe 27 corresponding to the inspection camera position, providing targeted cooling to the lens edge and the inside of the protective shell, further improving heat dissipation efficiency.

[0047] After passing through the heat dissipation stage, the gas continues to flow along the connecting pipe 27 and finally passes through the drainage pipe 29. At this time, the funnel-shaped drainage pipe 29 can accelerate the convergence of airflow, increase the outlet air pressure, and enter the centering ring cylinder 210. The centering ring cylinder 210 surrounds the outside of the end of the inspection camera. The nozzles 211 evenly distributed inside maintain an appropriate distance from the camera surface, and the groove design between every two adjacent nozzles 211 can avoid mutual interference of airflow. When the gas is ejected from the nozzles 211, it forms multiple precise annular airflows that fully cover the camera surface, powerfully blowing away the attached dust, rainwater, fog and other impurities. At the same time, the barrier formed by the airflow reduces the probability of external pollutants re-attaching.

[0048] When the electric actuator shaft 22 extends to its maximum stroke, the control module 11 issues a retraction command. The multi-section structure of the electric actuator shaft 22 retracts sequentially, causing the assembly plate 23 to slide in the opposite direction along the limit rod 24. The internal space of the outer cylinder 21 expands to form a negative pressure. The one-way valve 25 automatically closes due to the pressure difference on both sides to prevent backflow of external gas and contaminants. After the assembly plate 23 returns to its initial position, the electric actuator shaft 22 enters the extension cycle again. This process is repeated to achieve intermittent gas delivery. Throughout the process, the control module 11 adjusts the extension frequency and stroke of the electric actuator shaft 22 in real time based on the temperature data and camera imaging clarity parameters fed back by the inspection module 12, dynamically adjusting the gas delivery volume to ensure that the heat dissipation and purging effect are always adapted to the current inspection environment.

[0049] Based on Example 1, please refer to Figure 1 - Figure 9 As shown, a detection auxiliary mechanism 3 is provided on the side of the inspection module 12. The detection auxiliary mechanism 3 includes a first disc 31 sleeved on the outside of the inspection module 12. A second disc 32 is fixedly connected to the side wall of the first disc 31. A light shield 33 is fixedly connected to the side wall of the second disc 32. The light shield 33 is corrugated in shape and is located in the upper half of the second disc 32. A rotating ring 34 is rotatably connected inside the first disc 31. An electric rotating shaft 35 is fixedly connected to the surface of the rotating ring 34. The electric rotating shaft 35 is located away from the rotating ring 34. One end is installed inside the control module 11. The electric rotating shaft 35 is controlled by the control module 11. The surface of the rotating ring 34 is uniformly provided with curved grooves 36. The inside of each curved groove 36 is slidably connected with a linkage plate 37. A positioning ring 38 is installed on the side of the linkage plate 37 away from the curved groove 36. A right angle groove 39 is provided on each position of the positioning ring 38 near the linkage plate 37. The linkage plate 37 and the positioning ring 38 are slidably connected through the right angle groove 39, and the positioning ring 38 is fixedly connected to the inner wall of the second set of discs 32.

[0050] Specifically, when the inspection robot is not in operation, the components of the detection auxiliary mechanism 3 are in an initial retracted state: the first set of discs 31 are tightly fitted onto the outside of the protective shell of the inspection module 12 and are fixed to the shell; the second set of discs 32 are connected to the side wall of the first set of discs 31 by a fixed connection, and the two are kept in a tight fit; the rotating ring 34 is stationary inside the first set of discs 31, and the curved grooves 36 evenly distributed on its surface correspond one-to-one with the right-angle grooves 39 on the inner side wall of the positioning ring 38; the two ends of the linkage plate 37 are respectively embedded in the curved grooves 36 and the right-angle grooves 39, and because it is not driven by external force, it is retracted as a whole in the space formed by the two sets of discs and remains relatively stationary with respect to the positioning ring 38.

[0051] When the inspection module 12 starts and enters the working state, the control module 11 sends a command to the electric rotating shaft 35. The electric rotating shaft 35 starts to rotate and drives the rotating ring 34 to rotate synchronously in the first set of disks 31. This rotation amplitude is small, and it is only through the rotation of the rotating ring 34 that the relative displacement between the curved groove 36 and the right angle groove 39 is ensured. The arc path of the curved groove 36 generates a radial thrust on the embedded end of the linkage plate 37, while the right angle groove 39 provides a straight guide for the linkage plate 37. Under the dual action, the linkage plate 37 slides along the right angle groove 39 in a direction away from the axis of the inspection module 12, and gradually changes from the initial contracted state to the expanded state. Its sliding end in the curved groove 36 moves with the rotating ring 34, while the other end extends smoothly along the right angle groove 39. Throughout the process, the linkage plate 37 always maintains a posture parallel to the axis, and the positioning ring 38 drives the second set of disks 32 to form a stable distance with the first set of disks 31.

[0052] During this process, the design of the light shield 33 fixed to the upper half of the second set of discs 32 can be maintained by the position of the second set of discs 32, and can specifically cover the area above and to the side above the lens of the inspection module 12. The corrugated structure can weaken the direct intensity of side backlight and stray light through surface diffuse reflection, reducing the probability of light directly entering the lens. At the same time, it uses its own shape to form a physical blockage of light, avoiding overexposure or decreased contrast of the image caused by strong light interference, and ensuring that the inspection camera can clearly capture the details of the cable. When the inspection is completed, the control module 11 controls the electric rotating shaft 35 to rotate in the opposite direction, the rotating ring 34 drives the curved groove 36 to reset, and the linkage plate 37 retracts inward along the right angle groove 39 under the action of reverse thrust, returning to the initial position of being embedded in the curved groove 36. The second set of discs 32 and the positioning ring 38 re-attach to the first set of discs 31, and the entire detection auxiliary mechanism 3 returns to the retracted state, ready for the next inspection.

[0053] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
