Abstract

This invention discloses a modular safety protection device for an inspection robot, belonging to the field of inspection robot technology. The proposed solution includes a robot protection mechanism comprising an inspection robot with steering components and arc-shaped guide rails on both sides. The invention uses the steering components to drive a hydraulic control component to steer, causing the sliding rollers to enter the arc surface of the arc-shaped guide rails.

This provides targeted protection against strong light, rain, snow, or falling objects. Furthermore, the device, combined with buffer rods and buffer springs, further cushions impacts, allowing the inspection robot to flexibly adjust its protection mode in complex environments.

Description

Technical Field

[0001] This invention relates to the field of inspection robot technology, and in particular to a modular safety protection device for inspection robots. Background Technology

[0002] Inspection robots are widely used in complex environments such as power substations, chemical industrial parks, and mining tunnels. Their operating environments often present numerous safety hazards, such as falling objects from heights, impacts from ground obstacles, and erosion from severe weather. These hazards can easily damage the robot's body and cause malfunctions in core components (such as cameras), thus interrupting inspection operations and increasing maintenance costs. Therefore, safety protection devices are an indispensable core component of inspection robots, and their protective performance directly determines the robot's operational reliability and lifespan. However, existing safety protection devices are mostly fixed structures, providing protection against only a single risk and failing to adapt to the diverse risks in different scenarios. They lack switchable, targeted protective structures when facing strong light, rain, snow, or falling objects from heights. Furthermore, the protection design for cameras is inadequate; most only use fixed protective covers, which cannot withstand strong impacts and easily obstruct the lens, affecting image capture.

[0003] To address the above problems, this invention proposes a modular safety protection device for inspection robots. Summary of the Invention

[0009] Preferably, the steering assembly includes a fixed frame, which is fixedly connected to the inspection robot. A first motor is fixedly mounted on the fixed frame, and an adjusting shaft is fixedly connected to the output shaft of the first motor. The steering component is mounted on the adjusting shaft, and the adjusting shaft is rotatably mounted on the inspection robot via bearings.

[0010] Preferably, the protective component includes multiple protective frames, two of which are fixedly connected to the two sides of the upper cylinder respectively, a shielding cloth is fixedly connected to the top of the multiple protective frames, the multiple protective frames are hinged to two telescopic frames, the two ends of the telescopic frames are respectively hinged to one end of the two telescopic frames, two guide openings are provided on the protective frames, and multiple ends of the telescopic frames are slidably connected in the corresponding guide openings.

[0011] Preferably, the drive assembly includes a second motor, which is mounted on a support shaft. The output shaft of the second motor is fixedly connected to a first gear, and a second gear meshes with one side of the first gear. The second gear is rotatably mounted on the support shaft via a bearing structure.

[0012] Preferably, the active protection component includes a turntable, which is mounted on a bearing structure.

[0015] Compared with the prior art, the present invention provides a modular safety protection device for inspection robots, which has the following beneficial effects: 1. The modular safety protection device of this inspection robot uses a steering component to drive the hydraulic control component to turn, causing the sliding roller to enter the arc surface of the arc guide rail. At this time, the hydraulic control component drives the protection component to retract and position itself in front of the inspection robot to provide protection, effectively resisting the frontal impact of ground obstacles. Similarly, the protection component can automatically deploy when it moves above the inspection robot, thereby protecting the top of the inspection robot. This provides targeted protection against strong light, rain and snow, or falling objects from heights. In addition, the buffer rod and buffer spring can further buffer the impact, allowing the inspection robot to flexibly adjust the protection mode in complex environments.

[0016] 2. The modular safety protection device of this inspection robot can activate the drive component to rotate the active protection component and the passive protection component when an impact occurs through the hydraulic control component. On the one hand, centrifugal force can be used to throw the impacting object away to avoid damage to the camera. On the other hand, the passive protection component and the active protection component form a hollow protective cage structure, which can effectively reduce the obstruction rate of the detection probe and ensure that the camera can clearly record the dangerous process.

[0017] 3. The modular safety protection device of this inspection robot drives the hydraulic control component to rotate through the steering component. During the steering process of the hydraulic control component, the guide rail can realize the extension and retraction control of the protection component, thereby meeting the protection needs of the top and front of the inspection robot in multiple scenarios. This can help block interference light and rain and snow, improve the clarity of the detection probe. When encountering a strong impact that exceeds the buffer, the drive component drives the active protection component and the passive protection component to rotate, which can accurately resist the core risks of the detection probe and ensure that the inspection data is not interrupted. The two work together to achieve multi-level protection according to the impact intensity, which greatly reduces the failure rate and provides reliable safety guarantee for the stable inspection of the inspection robot in complex scenarios.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: Refer to Figures 1-6A modular safety protection device for inspection robots includes a robot protection mechanism 100, which includes an inspection robot 101. Both sides of the inspection robot 101 are provided with a steering component 102 and an arc-shaped guide rail 105. The steering component 102 includes a fixed frame 1021, which is fixedly connected to the inspection robot 101. A first motor 1022 is fixedly installed on the fixed frame 1021. An adjusting shaft 1023 is fixedly connected to the output shaft of the first motor 1022. A steering component 1069 is installed on the adjusting shaft 1023. The adjusting shaft 1023 is rotatably installed on the inspection robot 101 through a bearing. A hydraulic control component 106 is connected to the steering component 102. The hydraulic control assembly 106 includes a lower cylinder 1061, with a steering component 1069 fixedly connected to the lower part of the lower cylinder 1061. A lower piston rod 10610 is disposed inside the lower cylinder 1061, extending out of the lower cylinder 1061 and fixedly connected to a sliding roller 10611. The sliding roller 10611 is slidably connected in an arc-shaped guide rail 105. The sliding roller 10611 enters the arc surface of the arc-shaped guide rail 105, causing the lower piston rod 10610 to move upwards, thereby controlling the hydraulic pressure. The upper piston rod 1068 is controlled to move, causing the telescopic frame 1072 to automatically retract the shielding cloth 1073, thus achieving the effect of front protection for the inspection robot 101. When the sliding roller 10611 slides upward, the lower piston rod 10610 moves downward, which in turn hydraulically drives the upper piston rod 1068 to retract, causing the telescopic frame 1072 to unfold. The unfolding of the shielding cloth 1073 can smoothly achieve the effect of top protection for the inspection robot 101. The lower cylinder 1061 is connected to the hose 1066. The upper cylinder 1067 is connected to the upper cylinder 1067. A buffer structure 108 is fixedly connected above the two upper cylinders 1067. The buffer structure 108 can buffer the impact from the front. An upper piston rod 1068 is provided in the upper cylinder 1067. A buffer cavity 1062 is fixedly connected above the upper cylinder 1067. A pressure sensor 1063 is installed on the bottom wall of the buffer cavity 1062. The pressure sensor 1063 can detect the impact pressure of the buffer rod 1064 and convert the pressure signal into an electrical signal. This can activate the detection protection component to directly protect the detection probe 104. A buffer rod 1064 is provided in the buffer cavity 1062. The buffer rod 1064 extends upward through the buffer cavity 1062 and is fixedly connected to the upper cylinder 1067. A buffer spring 1065 is fixedly connected between the buffer rod 1064 and the upper wall of the buffer cavity 1062. The buffer rod 1064 can work with the buffer spring 1065 to further weaken the impact force, thereby improving the buffering effect. Above each of the two hydraulic control components 106, a protective component 107 is provided. The protective component 107 includes multiple protective frames 1071. Two of the protective frames 1071 are fixedly connected to the two sides of the upper cylinder 1067, respectively. A shielding cloth 1073 is fixedly connected above the multiple protective frames 1071. The shielding cloth 1073 can be made of high-strength waterproof material, which can play a good role in rain protection and impact protection. The multiple protective frames 1071 are hinged to two telescopic frames 1072. The two ends of the telescopic frames 1072 are respectively hinged to one end of the two telescopic frames 1072. The shielding cloth 1073 can be automatically opened and retracted by telescopic frames 1072, which is convenient for switching the use scenario and avoids affecting the line of sight of the detection probe 104. Two guide ports 1074 are opened on the protective frame 1071. The multiple ends of the telescopic frame 1072 are slidably connected in the corresponding guide ports 1074. The inspection robot 101 is equipped with a support shaft 103, and a detection probe 104 is installed on the top of the support shaft 103. A detection protection mechanism 200 for protecting the detection probe 104 is provided on the support shaft 103.

[0023] In this embodiment: the first motor 1022 drives the adjusting shaft 1023 to rotate the hydraulic control component 106, causing the sliding roller 10611 to enter the arc surface of the arc guide rail 105. At this time, the hydraulic control component 106 drives the telescopic frame 1072 to retract, the protective frame 1071 and the shielding cloth 1073 to retract, and are located in front of the inspection robot 101 to provide protection, effectively resisting the frontal impact of ground obstacles. Similarly, the protective component 107 can be automatically deployed when it moves above the inspection robot 101, thereby protecting the top of the inspection robot 101. This provides targeted protection when facing strong light, rain and snow, or falling objects from a height. Moreover, in conjunction with the buffer rod 1064 and the buffer spring 1065, it can further buffer the impact, allowing the inspection robot 101 to flexibly adjust the protection mode in complex environments.

[0024] Example 2: Refer to Figures 7-10The modular safety protection device for the inspection robot includes a detection and protection mechanism 200, which includes a drive assembly 201. The drive assembly 201 includes a second motor 2012, which is mounted on a support shaft 103. The output shaft of the second motor 2012 is fixedly connected to a first gear 2011. A second gear 2013 meshes with one side of the first gear 2011. The second gear 2013 is rotatably mounted on the support shaft 103 via a bearing structure 2014. The bearing structure 2014 ensures the smooth rotation of the second gear 2013 and the turntable 2021. An active protection assembly 202 is provided on the drive assembly 201. The active protection assembly 202 includes a turntable 2021, which is mounted on the bearing structure 2014. Multiple outer protective frames are fixedly connected above the turntable 2021. 2022, the inner protective frame 2032 and the outer protective frame 2022 are made of high-strength lightweight alloy material, which can effectively reduce the load while ensuring the protective strength. The top of multiple outer protective frames 2022 are fixedly connected to an outer ring 2023. The inner wall of the turntable 2021 is fixedly connected to a first magnet 2024 and a push plate 2025. After the turntable 2021 rotates, the outer protective frame 2022 is pre-rotated to the front of the detection probe 104. At this time, the outer protective frame 2022 and the inner protective frame 2032 form a protective cage to protect the detection probe 104. At the same time, when the turntable 2021 drives the first magnet 2024 to correspond with the second magnet 2045 and generate magnetic attraction, the pin 2041 can be automatically removed from the fixing of the positioning sleeve 109. Then the push plate 2025 can directly contact the limiting component 204, thereby driving the passive protection component 203 to rotate. The active protection component 202 includes a passive protection component 203. The passive protection component 203 includes a rotating ring 2031, which is connected to a turntable 2021 via a bearing. Multiple inner guards 2032 are fixedly connected to the top of the rotating ring 2031, and an upper plate 2033 is fixedly connected to the top of each inner guard 2032. The upper plate 2033 is connected to the outer ring 2023 via a bearing. A limit component 204 is connected to the bottom of the passive protection component 203. The limit component 204 includes a mounting sleeve 2044, which is fixedly connected to the bottom of the rotating ring 2031. A pin 2041 slides within the mounting sleeve 2044, with one end of the pin 2041 fitting into a positioning sleeve 109. One end of the 1 is fixedly connected to the operating lever 2042, and the other end of the pin 2041 is fixedly connected to the second magnet 2045. The second magnet 2045 and the mounting sleeve 2044 are fixedly connected to the first spring 2043. The first spring 2043 fixes the pin 2041, so that the pin 2041 is stably engaged in the positioning sleeve 109. This ensures that the active protection component 202 can rotate in advance. The first magnet 2024 moves to the position of the second magnet 2045, so that the first magnet 2024 and the second magnet 2045 magnetically attract the pin 2041 to be removed from the positioning sleeve 109. The limiting component 204 engages with the positioning sleeve 109, and the positioning sleeve 109 is fixedly connected to the support shaft 103. In this embodiment: when an impact occurs through the hydraulic control component 106, the impact signal can be sensed by pressure and the second motor 2012 can be started, causing the first gear 2011 and the second gear 2013 to drive each other. The bearing structure 2014 drives the active protection component 202 and the passive protection component 203 to rotate. On the one hand, centrifugal force can be used to throw the impacting object out to avoid damage to the camera. On the other hand, the passive protection component 203 and the active protection component 202 form a hollow protective cage structure, which can effectively reduce the obstruction rate of the detection probe 104 and ensure that the camera can clearly record the dangerous process.

[0025] Example 3: Reference Figures 1-3 , Figure 7 and Figure 9 The modular safety protection device for the inspection robot includes a robot protection mechanism 100, which includes an inspection robot 101. Both sides of the inspection robot 101 are provided with a steering component 102 and an arc-shaped guide rail 105. A hydraulic control component 106 is connected to the steering component 102, and a protection component 107 is provided above the two hydraulic control components 106. The inspection robot 101 is equipped with a support shaft 103, and a detection probe 104 is installed on the top of the support shaft 103. A detection protection mechanism 200 for protecting the detection probe 104 is provided on the support shaft 103. The detection and protection mechanism 200 includes a drive component 201, an active protection component 202 is provided on the drive component 201, a passive protection component 203 is provided inside the active protection component 202, a limit component 204 is connected below the passive protection component 203, the limit component 204 engages with the positioning sleeve 109, and the positioning sleeve 109 is fixedly connected to the support shaft 103.

[0026] In this embodiment: the steering component 102 drives the hydraulic control component 106 to rotate, so that the guide rail of the hydraulic control component 106 can realize the extension and retraction control of the protection component 107 during the steering process, thereby meeting the protection needs of the top and front of the inspection robot 101 in multiple scenarios. This can help block interference light and rain and snow, and improve the image clarity of the detection probe 104. When encountering a strong impact that exceeds the buffer, the drive component 201 drives the active protection component 202 and the passive protection component 203 to rotate, which can accurately resist the core risks of the detection probe 104 and ensure that the inspection data is not interrupted. The two work together to achieve multi-level protection according to the impact intensity, which greatly reduces the failure rate, thereby providing a reliable safety guarantee for the stable inspection of the inspection robot 101 in complex scenarios.

[0027] Working principle: When performing front protection for the inspection robot 101, the first motor 1022 drives the adjusting shaft 1023 to rotate. The adjusting shaft 1023 drives the steering component 1069 and the lower cylinder 1061 to rotate, causing the buffer rod 1064 to drive the upper cylinder 1067 to rotate. The upper piston rod 1068 drives the protection component 107 to rotate. At the same time, the lower piston rod 10610 drives the sliding roller 10611 to enter the arc surface of the arc guide rail 105. The lower piston rod 10610 generates an upward thrust, which causes the liquid to enter the upper cylinder 1067 through the hose 1066. The upper piston rod 1068 is hydraulically driven to drive the telescopic frame 1072 to retract. The telescopic frame 1072 drives the protective frame 1071 and the shielding cloth 1073 to retract smoothly. At this time, the buffer structure 108 protects against the impact in front, and the buffer rod 1064 and the buffer spring 1065 further buffer and protect. When top protection of the robot is required, the drive component 201 drives the hydraulic control component 106 to rotate upward, so that the protection component 107 moves above the inspection robot 101 and unfolds to achieve top protection. When the impact force is large, the buffer rod 1064 presses against the pressure sensor 1063. After the pressure sensor 1063 is under pressure, it controls the second motor 2012 to drive the first gear 2011 and the second gear 2013 through impact sensing. The bearing structure 2014 drives the turntable 2021 to rotate. The turntable 2021 drives the outer protective frame 2022 to rotate in advance. When the first magnet 2024 and the second magnet 2045 correspond and are magnetically attracted, the pin 2041 is disengaged from the positioning sleeve 109. Then the push plate 2025 directly drives the rotating ring 2031 to rotate through the limit component 204, causing the inner protective frame 2032 to rotate, thereby protecting the detection probe 104. At the same time, the detection probe 104 can successfully capture inspection data.

[0028] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
