Description

TECHNICAL FIELD

[0001] The application relates to the technical field of robot line inspection, in particular to a communication engineering installation line inspection robot. BACKGROUND

[0002] A communication engineering installation line inspection robot, the core value of the inspection robot is to replace manual line detection in complex, dangerous and inefficient scenes, the robot can walk along the line through wheels, tracks or crawling mechanisms, adapt to complex terrains around communication base stations, flexibly cope with high and low differences and small obstacles, integrate multi-dimensional perception systems such as high-definition zoom cameras and infrared thermal imaging, and accurately identify line looseness, line connection and other hidden dangers.

[0003] However, the prior art still has the following defects when used in detail:

[0004] 1. In the prior art, the lens of the inspection robot is easily affected by pollution and fogging; on the one hand, the outdoor inspection scene is complex, and pollutants such as rainwater and dust are irregularly attached, and the lens protection design only relies on passive protection, such as a simple dust cover and a basic anti-fog coating, lacks active cleaning intervention, and cannot remove dynamically attached pollutants in real time; on the other hand, in a high-temperature and high-humidity environment, there is a significant temperature difference between the lens and the outside air, and when the air humidity is saturated, water vapor quickly condenses into small droplets on the lens surface with lower temperature, the anti-fog coating can temporarily change the surface tension to delay fogging, but the hydrophilic and hydrophobic properties of the coating material will decay over time and temperature, and in continuous operation, the heat exchange between the lens and the environment constantly breaks the temperature balance, resulting in anti-fog failure.

[0005] During the inspection process, lens pollution and fogging can directly damage the imaging quality, making it impossible to identify cable defects such as fine cracks and joint abnormalities, resulting in missed detection by the robot, transferring the cost of manual inspection to the subsequent operation and maintenance link, and possibly causing communication failure; from the efficiency point of view, frequent manual intervention to clean the lens and restart the device is required due to image blur, which disrupts the preset inspection rhythm, prolongs the time consumption of a single task, and reduces the overall inspection coverage efficiency; more importantly, the risk of missed detection can accumulate into communication line failure, threatening the stability of the power grid and communication network, and even causing safety accidents, which weakens the core value of the inspection robot replacing manual work.

[0006] 2. Existing inspection robots have obvious deficiencies in lens protection and light interference prevention. First, when not in use, the lens is only protected by a fixed outer shell. There is an assembly gap between the outer shell and the lens, and there is no sealing structure, so dust and water vapor can easily enter through the gap; when in use, there is no effective light-shielding structure around the lens, and it is only equipped with a fixed short light-shielding hood with a fixed angle and limited coverage. Side backlight can invade from the side gaps, and stray light can be incident from all directions, making it impossible to intercept multi-directional light. These rays are superimposed on the main light path in the lens, destroying the imaging contrast.

[0007] The superposition of ambient light and the main light path will lead to a serious decline in image quality, with glare, light spots and local overexposure appearing in the picture. The edge details and minor defects of the cable will be obscured, making it difficult to clearly distinguish them. As a result, the subsequent detection algorithm will be unable to accurately identify problems such as broken wires and damaged insulators, greatly increasing the risk of missed detection. At the same time, it will also increase the workload and cost of manual re-inspection, affecting inspection efficiency.

[0008] In view of this, the present invention proposes a communication engineering installation line inspection robot to remedy and improve the shortcomings of the existing technology. Summary of the Invention

[0009] In order to solve the above technical problems, the present invention provides a communication engineering installation line inspection robot to solve the technical problems raised in the above background technology.

[0010] In order to achieve the above purpose, the technical solution adopted by the present invention is: a communication engineering installation line inspection robot, including an inspection carrier, a control module is installed above the inspection carrier, an inspection module is installed above the control module, and a detection pretreatment mechanism is provided on the side of the inspection module, and the detection pretreatment mechanism includes an external tube, an assembly plate is installed inside the external tube, and a connecting pipe is evenly installed at the output end of the external tube; the external tube and the inspection module are located on the same axis, and when the inspection module is in use, the external tube will intermittently push gas to the position of the inspection module through the reciprocating movement of the internal assembly plate, and the generated gas will be cooled when passing through the outside of 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. The motion controller is used to accurately control the robot's movement behavior, including speed, direction and position. The inspection module includes a protective shell and an inspection camera. The protective shell is a regular hexagon.

[0012] Furthermore, an electric push shaft is installed inside the external tube, and the electric push shaft as a whole has a multi-section telescopic structure. The fixed end of the electric push shaft is fixedly connected to the inner wall of the external tube, and the outer wall of the movable end is fixedly connected to the assembly plate. The electric push shaft is controlled by a control module and is in a retracted state in the initial state.

[0013] Furthermore, a limiting rod is symmetrically passed through the surface of the assembly plate through which the limit rod is slidably connected, both ends of the limiting rod are fixedly connected to the inner wall of the external tube, and a one-way valve is installed inside the output end of the external tube. In the initial state, the one-way valve is in a closed state.

[0014] Furthermore, the side wall of the output end of the external tube is sleeved with a supporting base, and the external tube and the connecting pipe are maintained in communication through the supporting base. The connecting pipe is located between the protective shell and the inspection camera in the inspection module. The connecting pipe is slidably connected to the inspection module and passes through the front and back sides of the inspection module. The connecting pipe is located at each diagonal position inside the protective shell, and the connecting pipe is provided with a notch at the position corresponding to the inspection camera.

[0015] Furthermore, a centering ring tube is installed at one end of the connecting pipe away from the supporting base, and drainage tubes are evenly installed between the connecting pipe and the centering ring tube. The connecting pipe, drainage tube and centering ring tube are kept connected. The drainage tube is funnel-shaped as a whole, and the centering ring tube is located outside the end of the inspection camera as a whole.

[0016] Furthermore, the interior of the centering ring is evenly connected with nozzles, the nozzles are in an arc shape as a whole, and a groove is provided between every two adjacent nozzles.

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

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

[0019] Furthermore, curved grooves are evenly penetrated through the surface of the rotating ring, and linkage plates are slidably connected to the inside of the curved grooves. A positioning ring is installed on the side of the linkage plate away from the curved grooves, and right-angle grooves are correspondingly opened at the positions of the positioning rings close to 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 set of discs.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) This device realizes intermittent purging of the inspection camera through the reciprocating movement of the internal assembly plate of the external tube, which can specifically solve the problem of the lens being easily contaminated and fogged in the existing technology. When the gas is gathered to the centering ring tube through the drainage tube and then ejected through the arc-shaped nozzle, the formed annular airflow can fully cover the surface of the camera, and promptly remove dynamically attached pollutants such as rainwater and dust to avoid them from forming obstructions or light spots on the lens, ensuring that the subtle defects on the edge of the cable are always clearly visible; compared with the existing technology, this active cleaning mechanism can respond to pollution in complex outdoor environments in real time, reduce the risk of missed inspections due to the accumulation of pollutants, and at the same time, the barrier formed by the airflow can reduce the probability of external pollutants attaching again, without the need for frequent manual intervention for cleaning, ensuring the continuity of the inspection work and reducing the cost of manual investigation.

[0022] During the actual purge process, the gas generated at the nozzle will undergo convection, and the convective airflow will form a dynamic circulation on the surface of the camera, which can enhance the ability to remove stubborn pollutants, avoid cleaning dead corners caused by uneven force of single-direction airflow, and ensure that every part of the lens can be fully purged. At the same time, the air curtain formed by convection can more effectively block the invasion of external water vapor and dust, reduce the probability of lens fogging and secondary pollution, especially in rainy and dusty environments. This structure allows the airflow to continuously maintain the cleanliness of the lens surface, ensuring that the image clarity is not affected; and the presence of the groove provides a buffer space for the convective airflow, preventing the airflows ejected from adjacent nozzles from interfering with each other to form turbulence, which not only ensures the stability of the airflow, but also guides part of the gas to flow along the edge of the lens, strengthening the cleaning of pollutants in the gaps.

[0023] What is particularly important is that when the airflow flows along the connecting pipe, it fully exchanges heat with the protective casing and camera through the pipe wall. Combined with the direct blowing of the notch on 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 decline in imaging accuracy or equipment damage due to overheating, but also delays the attenuation of the anti-fog coating performance, reduces the fogging phenomenon 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 operation and maintenance costs.

[0024] (2) This device effectively solves the problem of light interference in the existing technology through the shading design of the detection auxiliary mechanism. When the inspection module is started, the linkage plate drives the second set of discs to form a stable distance with the first set of discs. The corrugated light shield fixed on the upper half of the second set of discs can specifically cover the upper and upper side 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 shielding to avoid overexposure or contrast reduction caused by the superposition of strong light and the main light path, ensuring that the edge details and subtle defects of the cable are clearly visible. Compared with the problem of limited coverage of the fixed short light shield in the existing technology, the imaging quality in complex light environments is significantly improved.

[0025] The detection auxiliary mechanism can flexibly switch between the use and non-use states, taking into account both protection and convenience. When not working, the linkage plate retracts, and the second set of discs fits tightly against the first set of discs, making the entire mechanism compact, reducing the impact on the movement and storage of the robot, while avoiding damage to the shading structure due to external collisions; when working, the linkage plate expands to form a distance between the second set of discs and the first set of discs, ensuring that the light shield is in an effective shading position. This design overcomes the defects of insufficient protection of the lens fixed shell and the lack of a shrinking sealing structure in the prior art, enhances the protection of the lens peripheral structure without affecting use, and reduces the possibility of dust and water vapor invading through gaps.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0040] It should be noted that the structures and working principles of the above-mentioned inspection carrier 1, control module 11, inspection module 12 and other components belong to the existing technology 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 is installed above the inspection carrier 1, an inspection module 12 is installed above the control module 11, and a detection preprocessing mechanism 2 is provided on the side of the inspection module 12. The detection preprocessing mechanism 2 includes an external tube 21, an assembly plate 23 is installed inside the external tube 21, and a connecting pipe 27 is evenly installed at the output end of the external tube 21; the external tube 21 and the inspection module 12 are located on the same axis, and when the inspection module 12 is in use, the external tube 21 will intermittently push gas to the position of the inspection module 12 through the reciprocating movement of the internal assembly plate 23, and the generated gas will be cooled when passing through the outside of the inspection module 12, and will be purged when reaching 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 overall system control and data processing, and the motion controller is used for accurately controlling the motion behavior of the robot, including speed, direction and position, the inspection module 12 includes a protective shell and an inspection camera, and the protective shell is a regular hexagon.

[0044] Please refer to Figure 1 - Figure 9 As shown in the figure, the inside of the outer sleeve 21 is provided with an electric push shaft 22, the electric push shaft 22 is in a multi-section telescopic structure as a whole, the fixed end of the electric push shaft 22 is fixedly connected with the inner wall of the outer sleeve 21, the outer wall of the moving end is fixedly connected with the assembly plate 23, and the electric push shaft 22 is controlled to operate by the control module 11, and is in a retracted state in the initial state, the surface of the assembly plate 23 is symmetrically penetrated by a limiting rod 24 in sliding connection, both ends of the limiting rod 24 are fixedly connected with the inner wall of the outer sleeve 21, and the inside of the output end position of the outer sleeve 21 is provided with a check valve 25, which is in a closed state in the initial state, the side wall of the output end of the outer sleeve 21 is sleeved with a bearing base 26, the outer sleeve 21 and the communication pipeline 27 are kept in communication through the bearing base 26, the communication pipeline 27 is located between the protective shell and the inspection camera in the inspection module 12, the communication pipeline 27 is in sliding connection with the inspection module 12 and penetrates through the front and rear sides of the inspection module 12, the communication pipeline 27 is located at each diagonal position inside the protective shell, and each of the communication pipeline 27 is provided with a notch groove 28 at the position corresponding to the inspection camera, one end of the communication pipeline 27 away from the bearing base 26 is provided with a centering ring cylinder 210, and the communication pipeline 27 and the centering ring cylinder 210 are uniformly provided with a drainage pipe 29, the communication pipeline 27, the drainage pipe 29 and the centering ring cylinder 210 are kept in communication, the drainage pipe 29 is in a funnel shape as a whole, and the centering ring cylinder 210 is located outside the end of the inspection camera as a whole, the inside of the centering ring cylinder 210 is uniformly communicated with a nozzle 211, the nozzle 211 is in a circular arc shape as a whole, and each two adjacent nozzles 211 are spaced apart by a groove.

[0045] Specifically, when the inspection robot enters the inspection operation stage, the control module 11 sends a start signal to the detection preprocessing mechanism 2, and the electric push shaft 22 in the external tube 21 begins to reciprocate at a preset frequency. Since the electric push shaft 22 is in a fully retracted state in the initial state, its fixed end is firmly connected to the inner wall of the external tube 21, and the movable end is fixed to the assembly plate 23, so when the electric push shaft 22 receives the extension command, its multi-section structure extends outward in turn, pushing the assembly plate 23 along the limit rod 24 to the outer tube 21. The output end slides smoothly. As the assembly plate 23 moves, the enclosed space inside the external tube 21 continues to shrink 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 supporting base 26 through the output end of the external tube 21. The supporting base 26 serves as a diversion hub to evenly distribute the gas to multiple groups of connecting pipes 27. These pipes pass through the front and back sides of the inspection module 12 and are located diagonally inside the protective shell to form an airflow channel surrounding the inspection camera.

[0046] When the gas flows in the connecting pipe 27, on the one hand, it exchanges heat with the protective shell and the inspection camera through the pipe wall, and quickly takes away the heat generated by the inspection camera when it is working - especially in a high temperature environment, the continuous airflow can effectively reduce the operating temperature of the camera, avoiding the reduction of imaging accuracy or damage to the equipment due to overheating; on the other hand, part 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 position of the inspection camera, and the edge of the lens and the inside of the protective shell are cooled in a targeted manner, further improving the heat dissipation efficiency.

[0047] The gas that has passed through the heat dissipation link continues to flow along the connecting pipe 27 and finally passes through the drainage pipe 29. At this time, the drainage pipe 29 with a funnel-shaped structure can accelerate the convergence of the airflow, increase the outlet air pressure, and enter the centering ring tube 210. The centering ring tube 210 as a whole surrounds the outside of the end of the inspection camera. The nozzles 211 evenly distributed inside it maintain an adaptive 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 nozzle 211, multiple circular airflows with precise directions are formed, which fully cover the surface of the camera, and vigorously blow away impurities such as dust, rainwater, fog, etc., while using the barrier formed by the airflow to reduce the probability of external pollutants adhering again.

[0048] When the electric push shaft 22 is extended to its maximum stroke, the control module 11 issues a contraction command, and the multi-section structure of the electric push shaft 22 retracts in turn, driving the assembly plate 23 to slide in the opposite direction along the limit rod 24. The internal space of the external tube 21 expands to form a negative pressure, and the one-way valve 25 automatically closes due to the air pressure difference on both sides to prevent external gas and pollutants from flowing back. After the assembly plate 23 returns to its initial position, the electric push shaft 22 enters the extension cycle again, and intermittent gas delivery is achieved in this reciprocating manner. During the whole process, the control module 11 will adjust the extension and retraction frequency and stroke of the electric push shaft 22 in real time according to the temperature data and camera imaging clarity parameters fed back by the inspection module 12, and dynamically adjust the gas delivery volume to ensure that the heat dissipation and purge effects 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, and the detection auxiliary mechanism 3 includes a first set of discs 31 that are sleeved on the outside of the inspection module 12. The side wall of the first set of discs 31 is fixedly connected to the second set of discs 32. The side wall of the second set of discs 32 is fixedly connected to the light shield 33. The light shield 33 is in a corrugated shape as a whole and is located in the upper half of the second set of discs 32. The interior of the first set of discs 31 is rotatably connected to a rotating ring 34. The surface of the rotating ring 34 is fixedly connected to an electric shaft 35. The electric shaft 35 is away from the rotating ring 34. One end is installed inside the control module 11, and the electric shaft 35 is controlled by the control module 11. The surface of the rotating ring 34 is evenly penetrated with curved grooves 36, and the interior of the curved grooves 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. The positioning ring 38 is correspondingly provided with a right-angle groove 39 at the position close to 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 in a non-working state, the various components of the detection auxiliary mechanism 3 are in an initial contracted state: the first set of discs 31 is tightly sleeved on the outside of the protective shell of the inspection module 12 and is fixed to the shell; the second set of discs 32 is connected to the side wall of the first set of discs 31 by a fixed connection, and the two maintain a compact fit; the rotating ring 34 is in a stationary state inside the first set of discs 31, and the curved grooves 36 evenly distributed on its surface correspond one-to-one to the right-angle grooves 39 on the inner 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. Since it is not driven by external force, the whole is contracted in the space formed by the two sets of discs and remains relatively stationary with 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, and the electric rotating shaft 35 starts to rotate and drives the rotating ring 34 to rotate synchronously in the first set of discs 31. The rotation amplitude is small, and it is only through the rotation of the rotating ring 34 that the curved groove 36 and the right-angle groove 39 are ensured to produce relative displacement: the arc path of the curved groove 36 produces radial thrust on the embedded end of the linkage plate 37, and the right-angle groove 39 provides a linear guide for the linkage plate 37. Under the dual action, the linkage plate 37 slides along the right-angle groove 39 in the direction away from the axis of the inspection module 12, gradually changing from an initial contracted state to an expanded state - its sliding end in the curved groove 36 moves with the rotating ring 34, and the other end extends smoothly along the right-angle groove 39. During the whole process, the linkage plate 37 always maintains a posture parallel to the axis, and drives the second set of discs 32 and the first set of discs 31 to form a stable distance through the positioning ring 38.

[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 used to maintain the position of the second set of discs 32 to specifically cover the area above and above the side of the inspection module 12 lens. 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 for the light, avoiding overexposure or contrast reduction 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 shaft 35 to rotate in the opposite direction, and the rotating ring 34 drives the curved groove 36 to reset. The linkage plate 37 retracts inward along the right-angle groove 39 under the action of the reverse thrust and returns to the initial position embedded in the curved groove 36. The second set of discs 32 is re-fitted with the first set of discs 31 along with the positioning ring 38, and the entire detection auxiliary mechanism 3 returns to the retracted state, ready for the next inspection.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
