[0030] Example 1

[0031] refer to Figures 1-3 The wireless charging system for inspection robots includes a power supply system for charging piles and a charging system for inspection robots.

[0032] It includes a wireless charging system, which comprises a wireless power supply system and a wireless charging system;

[0033] The charging pile power supply system adopts a wireless power supply system;

[0034] The inspection robot charging system uses a wireless charging system.

[0035] The power supply system of the charging pile is equipped with a power supply induction coil 1, and the charging system of the inspection robot is equipped with a charging induction coil.

[0036] It also includes a magnetic attraction system for the charging pile power supply system and the inspection robot charging system;

[0037] The magnetic attraction system includes a first permanent magnet 2 disposed in the power supply system of the charging pile, and a second permanent magnet in the charging system of the inspection robot.

[0038] The power supply system of the charging pile is equipped with a retractable system, and the first permanent magnet 2 is located at the telescopic end of the retractable system.

[0039] The above design firstly, by setting up a wireless charging system and a power supply induction coil 1 for the wireless power supply system, the inspection robot can be charged without an exposed charging head, eliminating concerns about oxidation and dust accumulation, thus improving the stability of the inspection robot during long-term operation. Secondly, a magnetic attraction system is also set up. Through the first permanent magnet 2 in the charging pile power supply system and the second permanent magnet in the inspection robot charging system, the permanent magnets automatically calibrate their positions when they are attracted. During the inspection robot's charging, the charging pile and the inspection robot can be aligned and attracted together, improving the stability of the inspection robot's charging and reducing energy loss. Finally, the first permanent magnet 2 is located at the telescopic end of the telescopic system. The telescopic system is controlled by the inspection robot's central control system. When the inspection robot is charging, the telescopic system pushes the first permanent magnet 2 to the bottom surface of the power supply induction coil 1, and when it is charging, the telescopic system moves the first permanent magnet 2 to a position away from the bottom surface of the power supply induction coil 1, facilitating the docking and detachment of the inspection robot from the charging pile during charging, thus facilitating the daily operation of the inspection robot.

[0040] The charging pile power supply system includes a housing 3, and the power supply induction coil 1 is connected and disposed in the inner wall of the housing 3. The housing 3 is provided with a side strip 31, which extends outward from the side of the housing 3. The direction in which the side strip 31 extends outward is consistent with the electromagnetic emission direction of the power supply induction coil. At least three side strips 31 are provided, and the at least three side strips 31 form a positioning groove. The positioning groove matches the outer surface shape of the charging position of the inspection robot. The outward structure of the side strip 31 is chamfered towards the positioning groove. The positioning groove facilitates the accuracy and stability of the docking between the inspection robot and the charging pile.

[0041] At least one of the side strips 31 is located at the bottom, and at least two notches 32 are provided on the lower side strip 31; an inclined surface is provided above the notch 32, and the height of the inclined surface gradually decreases from both sides of the notch 32 toward the middle of the notch 32; when the inspection robot docks with the positioning slot in the charging pile, the at least two notches 32 on the lower side strip 31 can be used to calibrate the drive wheel of the inspection robot through the inclined surface, thereby facilitating the inspection robot to return to the charging pile position.

[0042] The outer casing 3 also includes a first pipe 5, one end of which is fitted around the induction coil. A second pipe 4 is also fitted around the first pipe, and the first pipe 5 and the second pipe 4 are concentrically arranged. The first permanent magnet 2 is disposed in the middle channel between the first pipe 5 and the second pipe 4, and slides along the middle channel. The first pipe 5 and the second pipe 4 facilitate the sliding of the first permanent magnet 2.

[0043] The wall thickness of the outer casing 3 at the location where the first pipe 5 and the second pipe 4 are installed is less than 5mm; the maximum distance between the first permanent magnet 2 and the bottom of the intermediate channel is 30-60mm. The wall thickness of the outer casing 3 being less than 5mm ensures the strength of the attraction force when the first permanent magnet 2 and the second permanent magnet attract each other, and the maximum distance between the first permanent magnet 2 and the bottom of the intermediate channel being 30-60mm ensures that the first permanent magnet 2 and the second permanent magnet are sufficiently far apart to not affect the movement of the inspection robot after it is fully charged.

[0044] In use, the retractable system is controlled by the central control system of the inspection robot. When the inspection robot is charging, the retractable system pushes the first permanent magnet 2 to the bottom of the power supply induction coil 1. During the charging process, the charging pile and the inspection robot can be aligned and attracted together, which improves the charging stability of the inspection robot and reduces energy loss. When the inspection robot is charging, the retractable system moves the first permanent magnet 2 to a position away from the bottom of the power supply induction coil 1, which facilitates the separation of the inspection robot from the charging pile during charging and makes it convenient for the daily work of the inspection robot.

[0045] Example 2

[0046] refer to Figure 1 and Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0047] The telescopic system includes a screw telescopic stepper motor 8, which is fixed to the outer casing 3 and located on the side opposite to the central channel. The screw 81 of the screw telescopic stepper motor 8 points towards the first permanent magnet 2, and a rotary head is provided at the top of the screw 81, which serves as the telescopic end of the telescopic system. The telescopic system also includes a frame 6, one end of which is connected to the first permanent magnet 2, and the other end of which engages with the rotary head. A rotary groove is provided in the frame 6, and the rotary head can be rotatably embedded in the rotary groove, driving the frame 6 to move back and forth. The screw telescopic stepper motor 8 ensures that the telescopic end has sufficient tension, and the engagement of the rotary head and the rotary groove facilitates the pulling of the frame 6 when the screw 81 rotates without the frame 6 rotating.

[0048] The frame 6 is provided with at least two connecting columns, and the at least two connecting columns are parallel to the extension direction of the screw 81; the stability of the first permanent magnet 2 when sliding is ensured by providing two connecting columns.

[0049] The outer casing is also provided with a fixing frame 7, which has at least two openings. The connecting post passes through the openings, and the positions of the at least two openings and the at least two connecting posts correspond one-to-one. By setting the openings of the fixing frame 7 and the connecting posts to slide, the first permanent magnet 2 and the frame 6 can slide horizontally, which facilitates the pushing and pulling of the first permanent magnet 2 in the middle channel and improves its operational stability.

[0050] During use, as the screw telescopic stepper motor 8 rotates and pulls, the rotary head rotates in the rotary groove and drives the frame 6 to slide along the opening, facilitating the pulling out of the first permanent magnet 2. The cooperation between the rotary head and the rotary groove makes it convenient for the screw 81 to pull the frame 6 while the frame 6 does not need to rotate, thus facilitating the pushing and pulling of the first permanent magnet 2 in the middle channel and improving the stability of the operation of the first permanent magnet 2.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
