[0002] Grid line inspection refers to the process of regular inspection, maintenance and management of power transmission lines. Grid lines are important channels for transmitting electricity generated by power plants to various users. Therefore, grid line inspection needs to ensure the safe operation of the grid, reduce power outages caused by line failures, and guarantee the electricity demand of users. In order to consider the safety of grid line inspection and ensure that inspection personnel can remotely inspect the lines, the introduction of grid line inspection robots can effectively improve the safety of the grid and reduce the cost and risk of manual inspections.

[0003] However, traditional power grid line maintenance robots need to be manually charged regularly, which is inefficient and requires human intervention. When a power grid line maintenance robot with a wireless charging function is actually used, the wireless charging coil at the bottom of the battery needs to be aligned with the charging pile before charging. However, the height difference of the line may make alignment difficult, thereby affecting the wireless charging effect of the robot and causing unstable power. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 An embodiment of the utility model provides a robot for power grid line operation and inspection, including: a shell 1 and a wireless induction charging pile 14.

[0020] Among them, Figure 1 As shown, an obstacle detection mechanism 17 is installed inside the shell 1, and the obstacle detection mechanism 17 includes an ultrasonic sensor and a temperature sensor. The wireless induction charging pile 14 is installed on the power tower; two running wheels 2 are symmetrically installed inside the shell 1, and a first motor 10 is installed at the bottom of the shell 1. The rotating shaft of the first motor 10 passes through the bottom of the shell 1 and is fixedly connected to the end of one of the running wheels 2.

[0021] The power grid line operation and inspection robot is equipped with a battery 5 with a wireless induction charging coil 13. The power grid line runs through the inside of the shell 1 and fits between two running wheels 2. By starting the first motor 10 to drive one of the running wheels 2 to rotate, the shell 1 moves on the power grid line, and uses the obstacle detection mechanism 17 to sense and detect the surface temperature of the power grid line and obstacles.

[0022] Furthermore, two linear grooves 8 are symmetrically provided at the top and bottom of the shell 1, and a slider 16 is slidably installed inside the linear groove 8. The top and bottom of one of the walking wheels 2 are rotatably installed on the opposite sides of the two sliders 16, and the opposite sides of the two sliders 16 are threadedly connected with fastening bolts 7.

[0023] The top and bottom of one of the running wheels 2 are installed on two sliders 16, and the running wheel 2 is moved laterally along the linear groove 8 by sliding the slider 16. The distance between the two running wheels 2 is adjusted to adapt to cables of different diameters, and the slider 16 is fastened in the linear groove 8 by rotating the fastening bolt 7.

[0024] In this embodiment, Figure 1As shown, two vertical rails 3 are symmetrically installed at the bottom of the shell 1, and a movable rod 4 is slidably installed inside the vertical rails 3. A battery 5 is installed at one end of the bottom of the movable rod 4, and a threaded rod 6 is fixedly connected to the top of the battery 5. A second motor 11 is installed at the bottom of the shell 1, and the rotating shaft of the second motor 11 is fixedly connected to an internal threaded tube 12. The threaded rod 6 is threadedly connected to the inside of the internal threaded tube 12, and a wireless induction charging coil 13 is installed at the bottom of the battery 5, and the wireless induction charging coil 13 is electrically connected to the battery 5.

[0025] When the capacity of the battery 5 is low, it can be moved to the vicinity of the power tower of the power grid and close to the wireless induction charging pile 14, and enter the wireless charging induction area to wirelessly charge the battery 5. In order to ensure that the position of the wireless induction charging coil 13 at the bottom of the battery 5 is located above the wireless induction charging pile 14 for charging, when the battery 5 is close to the wireless induction charging pile 14, the internal threaded barrel 12 can be rotated by starting the second motor 11, so that the threaded rod 6 can be lifted and lowered in the internal threaded barrel 12, and the battery 5 and the wireless induction charging coil 13 can be lifted and lowered.

[0026] Furthermore, infrared receivers 9 are installed on both sides and the bottom of the battery 5, and an infrared transmitter 15 is installed on the top of the wireless induction charging pile 14. The wireless induction charging pile 14 can use the infrared transmitter 15 to send infrared signals. When the battery 5 approaches the wireless induction charging pile 14, the infrared receiver 9 can receive the infrared signal to determine whether it is close to the wireless induction charging pile 14. In addition, the infrared receiver 9 can also determine whether the height of the battery 5 is above the wireless induction charging pile 14 through the infrared signal sent by the infrared transmitter 15.

[0027] like Figure 1 As shown, a controller 18 is installed inside the housing 1, and the signal output ends of the obstacle detection mechanism 17 and the infrared receiver 9 are connected to the signal input end of the controller 18, and the controller 18 is electrically connected to the first motor 10 and the second motor 11 respectively.

[0028] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: the power grid line operation and inspection robot provided by the utility model includes an outer shell 1 and running wheels 2, and is equipped with a battery 5 with a wireless induction charging coil 13. The power grid line runs through the inside of the outer shell 1 and fits between the two running wheels 2. By starting the first motor 10 to drive one of the running wheels 2 to rotate, the outer shell 1 moves on the power grid line, and uses the obstacle detection mechanism 17 to sense and detect the surface temperature of the power grid line and obstacles.

[0029] When the capacity of the battery 5 is low, it can be moved to the vicinity of the power tower of the power grid and close to the wireless induction charging pile 14, and enter the wireless charging induction area to wirelessly charge the battery 5. In order to ensure that the position of the wireless induction charging coil 13 at the bottom of the battery 5 is located above the wireless induction charging pile 14 for charging, when the battery 5 is close to the wireless induction charging pile 14, the internal threaded barrel 12 can be rotated by starting the second motor 11, so that the threaded rod 6 is lifted and lowered in the internal threaded barrel 12, and the battery 5 and the wireless induction charging coil 13 are driven to lift and lower. By changing the height of the battery 5, the phenomenon of being unable to approach wireless charging due to the height difference between the wireless induction charging coil 13 and the wireless induction charging pile 14 is avoided, thereby improving the flexibility of wireless charging of the power grid line inspection robot.

[0030] In order to prevent the battery 5 from rotating or tilting during the lifting and lowering process, a vertical rail 3 is installed at the bottom of the shell 1. The movable rod 4 at the top of the battery 5 can be lifted and lowered on the vertical rail 3 during the rotation of the internal threaded tube 12, thereby improving the stability of the battery 5 and preventing the battery 5 from rotating and tilting.

[0031] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
