[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a fall prevention device for a power transmission line inspection robot, such as... Figure 1-4 As shown, the fall protection device for the power transmission line inspection robot includes: mounting plates 2 fixed on both sides of the robot body 1; a connecting rod 3 installed on the top of the mounting plate 2; a limiting wheel 4 rotatably mounted on the connecting rod 3, the limiting wheel 4 having a slot 6 that can be locked onto the outside of the power transmission line; a motor box 5 fixed on the connecting rod 3 and connected to the limiting wheel 4 for driving the limiting wheel 4 to rotate; a limiting box 7 movably sleeved on the connecting rod 3, the limiting box 7 having a baffle 8 installed on it for closing the slot 6; and a limiting component set on the limiting box 7 for stabilizing the height of the limiting box 7.

[0022] In this embodiment, the inspection robot body 1 serves as the main body of the entire inspection system, responsible for performing inspection tasks on the power transmission line. By incorporating the fall protection device of this patent, the stability and safety of the inspection robot in complex environments are improved. The mounting plate 2 serves as the foundation for connecting other components, providing a stable mounting platform to ensure that subsequent components can be securely installed on the robot. The connecting rod 3 serves as a key structural support, ensuring that the limit wheel 4 can rotate smoothly and providing an installation position for the motor box 5. When the robot encounters obstacles or unstable conditions, the limit wheel 4 can clamp onto the power transmission line to prevent the robot from falling. The design of the slot 6 increases the contact area with the power transmission line, improving stability. The motor box 5 is used to drive the limit wheel 4 to rotate. Through the drive of the motor, the position and angle of the limit wheel 4 can be adjusted to better adapt to the shape of the power transmission line and obstacles, ensuring the safety of the robot. The baffle 8 can close the slot 6 to prevent the limit wheel 4 from detaching from the power transmission line, increasing stability.

[0023] In a further preferred embodiment of the present invention, the limiting component includes a cylinder 10, a spring 11, and a locking block 12. The cylinder 10 is fixed on the limiting box 7, the spring 11 is installed inside the cylinder 10, the locking block 12 is fixed on the spring 11, and the connecting rod 3 is provided with a locking slot 15, the locking block 12 can extend into the locking slot 15.

[0024] In this embodiment, the cylinder 10 serves as the mounting base for the spring 11 and the locking block 12, providing a stable mounting environment that ensures the normal operation of the spring 11 and the locking block 12. This also helps improve the durability and reliability of the entire limiting assembly. The elastic force of the spring 11 allows the locking block 12 to fit tightly into the latch 15 of the connecting rod 3, thereby increasing the stability of the limiting assembly. Simultaneously, the elasticity of the spring 11 also allows the locking block 12 to have some buffer space when subjected to external force, preventing damage due to excessive compression. The locking block 12 is a key component in the limiting assembly. By cooperating with the latch 15 of the connecting rod 3, it stabilizes the height of the limiting box 7. When the connecting rod 3 rises or falls, the locking block 12 automatically adjusts its position under the push of the spring 11, ensuring it always maintains tight contact with the latch 15, thus preventing the limiting box 7 from shaking or falling off.

[0025] In a further preferred embodiment of the present invention, a limiting plate 9 for supporting the limiting box 7 is fixed on the connecting rod 3. The limiting plate 9 is located below the bayonet 15, and a shock-absorbing pad 17 that can contact the bottom of the limiting box 7 is fixed on the top of the limiting plate 9.

[0026] In this embodiment, the limiting plate 9 provides a stable support surface, which effectively supports the limiting box 7 in the vertical direction. This design not only enhances the stability of the entire fall protection device, but also reduces the displacement of the limiting box 7 caused by shaking or external force, thereby ensuring that the fall protection device can always remain in the correct position. The shock-absorbing pad 17 is designed to absorb and disperse the impact force that may be generated between the limiting box 7 and the limiting plate 9, and also improves the durability and reliability of the entire fall protection device.

[0027] In a further preferred embodiment of the present invention, the cylinder 10 is provided with a movable opening, and the locking block 12 is fixed with a guide rod 13 that can extend to the outside of the cylinder 10 through the movable opening, and a pull ring 14 is fixed on the guide rod 13.

[0028] In this embodiment, the movable opening provides a channel for the guide rod 13, allowing it to extend smoothly to the outside of the cylinder 10. The design of the movable opening enables the guide rod 13 and the connected pull ring 14 to be easily operated and adjusted without interfering with the internal structure of the cylinder 10. This design not only improves the flexibility and operability of the entire device but also ensures the integrity and safety of the internal structure. The guide rod 13 acts as a bridge connecting the locking block 12 and the pull ring 14, allowing the operator to easily control the position and state of the locking block 12 through the pull ring 14. When it is necessary to adjust the fit between the locking block 12 and the locking slot 15 on the connecting rod 3, the operator only needs to pull the guide rod 13 through the pull ring 14 to move the locking block 12 up and down, thereby adjusting the tightness of the limiting component.

[0029] In a further preferred embodiment of this utility model, the limiting wheel 4 is externally fixedly fitted with a rubber anti-slip sleeve 16 that can contact the power transmission line, and the baffle 8 can contact the inner wall of the slot 6.

[0030] In this embodiment, the rubber anti-slip sleeve 16 is designed to enhance the friction between the limiting wheel 4 and the power transmission line, thereby improving the stability and safety of the inspection robot on the power transmission line. In complex environments, such as when there are obstacles such as arcs, clamps, and spacers on the power transmission line, the rubber anti-slip sleeve 16 can ensure that the limiting wheel 4 is tightly attached to the power transmission line, preventing the robot from falling due to slipping or shaking. In addition, the rubber material also has a certain degree of elasticity and wear resistance, which can extend the service life of the limiting wheel 4. Under normal circumstances, the baffle 8 closes the slot 6. When needed, the baffle 8 can be opened to allow the limiting wheel 4 to move away from the power transmission line.

[0031] In a further preferred embodiment of this utility model, the motor box 5 consists of a protective shell and a motor. The protective shell is mounted on the connecting rod 3, the motor is fixed inside the protective shell, the output shaft of the motor is connected to the limiting wheel 4, and copper foil for isolating electromagnetic signals is pasted on the inner wall of the protective shell.

[0032] In this embodiment, the design of the motor box 5 integrates the motor and its related components into a compact and fully functional structural unit. This design not only improves the integration and aesthetics of the entire inspection robot, but also facilitates the installation, maintenance, and replacement of the motor. The main function of the protective shell is to prevent the motor from being interfered with or damaged by the external environment. It provides a robust shell that can resist the intrusion of wind, rain, dust, and other impurities, thereby ensuring that the motor can operate stably for a long time. In addition, the protective shell can also play a certain role in sound insulation and vibration reduction, reducing the noise and vibration of the motor during operation. The motor is a key component that drives the rotation of the limit wheel 4. The design of the copper foil is mainly to reduce the electromagnetic interference generated during the operation of the motor, which is of great significance for ensuring the stability and reliability of other electronic devices inside the inspection robot.

[0033] In a further preferred embodiment of the present invention, an isolation plate is installed between the spring 11 and the locking block 12, and the isolation plate is in contact with the outer wall of the limiting box 7.

[0034] In this embodiment, the presence of the isolation plate limits the range of movement of the locking block 12 on the spring 11, preventing the locking block 12 from excessively disengaging from the cylinder 10, which could affect the service life of the spring 11, cause damage to the spring 11, and thus affect the adjustment of the position of the baffle 8.

[0035] In summary, compared with related technologies, this device, through the coordinated action of components such as mounting plate 2, connecting rod 3, limiting wheel 4, and motor box 5, ensures that the robot can smoothly inspect power transmission lines and effectively prevents falls when encountering obstacles or unstable conditions. At the same time, the design of limiting components, limiting plate 9, and shock-absorbing pad 17 further enhances the stability and durability of the device. In addition, the detailed design of rubber anti-slip sleeve 16 and copper foil also improves the functionality and safety of the device. Overall, the anti-fall device of this utility model provides a more reliable and safer guarantee for power transmission line inspection robots.
