DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] The present invention provides a robot for power inspection, such as Figures 1 to 4 As shown, it includes a vehicle body 1, which moves on the ground using multiple wheels on the bottom surface. A slide groove is provided on the top of the vehicle body 1, and a moving frame 2 is movably installed inside the slide groove. Side bars 3 are fixed on both sides of the moving frame 2, and inner grooves corresponding to the side bars 3 are provided on both inner side walls of the slide groove. A cylinder is installed inside the slide groove, and the output end of the cylinder is transmission-connected to the side of the moving frame 2. When the cylinder works, the output end of the cylinder pushes the moving frame 2 to move inside the slide groove. A lifting component is installed on the moving frame 2, and a mounting platform 4 is fixed on the front side of the moving frame 2 using the lifting component. The lifting component controls the mounting platform 4 to move up and down. A ring 5 is provided on the front side of the mounting platform 4, and a camera 6 is installed on the inner side of the ring 5 using a buffer component. A lens 7 is provided on the front side of the camera 6, and the camera 6 uses the lens 7 to inspect the power system. When it is necessary to inspect the power system, the vehicle body 1 is started, and the vehicle body 1 moves on the ground using multiple wheels. The moving vehicle body 1 detects the power system in real time through the lens 7 at the front side end of the camera 6, and the moving vehicle body 1 inspects the power system using the lens 7. The cylinder is started, and the cylinder output end pushes the moving frame 2 to move inside the slide groove of the vehicle body 1. The moving moving frame 2 moves inside the inner groove using the side bars 3. The side bars 3 cooperate with the inner groove to prevent the moving frame 2 from shifting during the sliding process inside the slide groove. The moving moving frame 2 drives the camera 6 inside the mounting platform 4 to move synchronously using the lifting component. The moving camera 6 uses the lens 7 to approach the power equipment, which is convenient for accurate detection of the power equipment.

[0027] exist Figure 1 and Figure 2In the figure, the lifting component includes two rotating rods 8, both of which are located on the inner side of the mobile frame 2, and the top of the rotating rod 8 passes through the top surface of the mobile frame 2, a gear 9 is fixed to the top of the rotating rod 8, and a rack 10 is arranged on the top surface of the mobile frame 2. The two gears 9 are matched by the rack 10 for transmission, and a lifting plate 11 is arranged on the inner side of the mobile frame 2, and the center of the front side of the lifting plate 11 is connected to the mounting platform 4, the rotating rod 8 spirally passes through the end of the lifting plate 11, and the spiral cooperation of the rotating rotating rod 8 and the lifting plate 11 makes the lifting plate 11 move up and down on the inner side of the mobile frame 2, and the top surface of the gear 9 is transmission-connected to the output end of the motor, and the motor is fixedly mounted on the top surface of the mobile frame 2. Start the motor, and the motor output end drives the gear 9 to rotate. The rotating gear 9 uses the rack 10 to drive another gear 9 to rotate synchronously. The rotating gear 9 drives the rotating rod 8 to rotate inside the mobile frame 2. At this time, the two rotating rods 8 rotate synchronously. Since the rotating rod 8 spirally penetrates the end of the lifting plate 11, the rotating rotating rod 8 and the spiral cooperation of the lifting plate 11 make the lifting plate 11 move up and down inside the mobile frame 2. The up and down movement of the lifting plate 11 is used to control the synchronous up and down movement of the camera 6 on the front side of the mounting platform 4. The lens 7 of the camera 6 facilitates real-time inspection of power equipment at different heights.

[0028] exist Figures 2 to 5 In the embodiment, the buffer component includes an inner ring 12, which is located on the inner side of the circular ring 5. A groove is provided on the front side of the mounting platform 4, which corresponds to the circular ring 5. Two opposite ring strips are fixed to the inner side wall of the inner ring 12, and the inner end faces of the ring strips are provided with internal threads. A threaded strip is provided on the surface of the camera 6, and the camera 6 is spirally plugged into the inner side of the inner ring 12 using the two ring strips. Two opposite protrusions 13 are fixed on the outer side of the circumference of the inner ring 12. A side groove corresponding to the protrusion 13 is provided on the surface of the circular ring 5. An inner rod 14 is provided inside the side groove. The protrusion 13 is sleeved on the surface of the inner rod 14. A spring 15 is sleeved on the surface of the inner rod 14. One end of the spring 15 is connected to the rear side of the protrusion 13, and the other end of the spring 15 is connected to the front side of the groove. When the front side of the buffer component contacts the electrical equipment, the reaction force of the electrical equipment on the buffer component causes the camera 6 to drive the inner ring 12 to move backward, and the inner ring 12 gradually moves toward the inside of the groove. The moving inner ring 12 slides on the surface of the inner rod 14, and the moving inner ring 12 uses the protrusion 13 to cooperate with the spring 15 on the surface of the inner rod 14, and uses the elastic force of the spring 15 to absorb the impact force between the electrical equipment and the buffer component, thereby avoiding the impact force directly acting on the surface of the lens 7, thereby facilitating the protection of the lens 7.

[0029] exist Figure 3 and Figure 5In the figure, two ring strips are provided with grooves 16 on their surfaces, a slide bar 17 is inserted into the outer end of the groove 16, a rear slide plate 18 is fixed to the rear end of the slide bar 17, the two rear slide plates 18 are arranged opposite to each other, and the two opposite rear slide plates 18 are connected by a spring sheet 19, and two opposite wedge blocks 20 are provided on the inner side wall of the groove circumference, and the inner inclined surface of the wedge block 20 corresponds to the outer side surface of the rear slide plate 18. The slide bar 17 moves synchronously driven by the buffer component, and the moving slide bar 17 drives the rear slide plate 18 to enter the groove until the outer side surface of the rear slide plate 18 contacts the inner inclined surface of the wedge block 20. The rear slide plate 18 continues to move backward and slides on the inner inclined surface of the wedge block 20. The pressure of the inner inclined surface of the wedge block 20 on the rear slide plate 18 makes the rear slide plate 18 close to the camera 6. The moving rear slide plate 18 drives the slide bar 17 close to the camera 6, and the moving slide bar 17 slides inside the groove 16. At this time, the two relative rear slide plates 18 approach each other and cooperate to squeeze the spring sheet 19, and the elastic force of the spring sheet 19 is used to further buffer the impact force of the power equipment and the buffer component, thereby further improving the protection effect on the lens 7.

[0030] exist Figure 3 and Figure 5 In the figure, a front slide plate 21 is fixed to the front end of the slide bar 17, a circular plate 22 is provided on the front side of the camera 6, the lens 7 is located at the center of the front side of the circular plate 22, two limiting plates 23 corresponding to the front slide plate 21 are fixed to the rear side of the circular plate 22, a moving plate 24 is provided between the two limiting plates 23, the moving plate 24 is located at the front side of the front slide plate 21, and the surface of the limiting plate 23 is provided with side grooves corresponding to the moving plate 24, a screw rod penetrating the front slide plate 21 is fixed to the rear side of the moving plate 24, and a nut is spirally sleeved on the rear end of the screw rod. The movable rear slide plate 18 utilizes the slide bar 17 to drive the front slide plate 21 to synchronously approach the camera 6. The front slide plate 21 utilizes the screw and nut to drive the movable plate 24 to move inside the side grooves of the two limiting plates 23, and the moving front slide plate 21 gradually approaches the outer circumferential surface of the camera 6 until the inner concave surface of the front slide plate 21 fits against the surface of the camera 6. The impact force of the power equipment on the buffer component is absorbed by the spring 15 and the shrapnel 19 to avoid the impact force acting on the camera 6 and the lens 7, so that the camera 6 can be fully protected to ensure the safety of the camera 6 during the inspection process.

[0031] exist Figure 2 , Figure 3 and Figure 5In the embodiment, two opposite arc plates 25 are inserted on the surface of the circular plate 22, and the arc plates 25 are made of transparent rubber material. The rear end of the camera 6 is provided with a side strip 26 corresponding to the arc plates 25. The front sides of the two arc plates 25 are pasted with transparent films 27, and the rear sides of the transparent films 27 are correspondingly pasted on the surface of the lens 7. The transparent films 27 are pasted on the front sides of the two arc plates 25, and when the buffer component is close to the power equipment, when the front side of the arc plate 25 contacts the power equipment, the impact force of the power equipment on the arc plate 25 causes the arc plate 25 to move, and the transparent film 27 prevents the power equipment from contacting the lens 7, which is convenient for protecting the lens 7, and the lens 7 detects the power equipment through the transparent film 27.

[0032] The circular plate 22 is provided with an annular groove 28 corresponding to the arc plate 25 on its surface, and a rubber strip 29 is provided inside the annular groove 28, one end of the rubber strip 29 is connected to the arc plate 25, and the other end of the rubber strip 29 is connected to the inner end surface of the annular groove 28. The two arc plates 25 correspond to the two front slide plates 21 one by one, and a connecting frame 30 is installed on the side of the front slide plate 21 by screws, and one end of the connecting frame 30 is hinged to the side of the arc plate 25. The impact force causes the arc plate 25 to drive the front slide plate 21 to move backward by using the connecting frame 30, and the front slide plate 21 uses the screw and nut to make the circular plate 22 move synchronously with the front slide plate 21, and the moving circular plate 22 drives the protrusion 13 on the inner ring 12 to squeeze the spring 15 through the camera 6, and the moving front slide plate 21 drives the rear slide plate 18 to move backward synchronously by using the slide bar 17.

[0033] When the front slide plate 21 approaches the camera 6, the moving front slide plate 21 uses the connecting frame 30 to push the arc plate 25 to slide inside the annular groove 28, and the moving arc plate 25 cooperates to squeeze the rubber strip 29 inside the annular groove 28. The moving arc plate 25 drives the transparent film 27 to rotate on the surface of the lens 7. The rotating transparent film 27 wipes the surface of the lens 7, which is convenient for cleaning the lens 7 and maintaining the clarity of the lens 7.

[0034] Working principle of the present invention:

[0035] Reference Figures 1 to 5 As shown, the vehicle body 1 is started, and the vehicle body 1 moves on the ground using multiple wheels. The moving vehicle body 1 detects the power system in real time through the lens 7 at the front side end of the camera 6, and the moving vehicle body 1 inspects the power system using the lens 7. The cylinder is started, and the cylinder output end pushes the moving frame 2 to move inside the slide groove of the vehicle body 1. The moving moving frame 2 moves inside the inner groove using the side bars 3. The side bars 3 cooperate with the inner groove to prevent the moving frame 2 from deviating during the sliding process inside the slide groove. The moving moving frame 2 drives the camera 6 inside the mounting platform 4 to move synchronously using the lifting component, and the moving camera 6 uses the lens 7 to approach the power equipment.

[0036] Start the motor, and the motor output end drives the gear 9 to rotate. The rotating gear 9 uses the rack 10 to drive another gear 9 to rotate synchronously. The rotating gear 9 drives the rotating rod 8 to rotate inside the mobile frame 2. At this time, the two rotating rods 8 rotate synchronously. Since the rotating rod 8 spirally penetrates the end of the lifting plate 11, the rotating rotating rod 8 and the spiral cooperation of the lifting plate 11 make the lifting plate 11 move up and down inside the mobile frame 2. The up and down movement of the lifting plate 11 is used to control the synchronous up and down movement of the camera 6 on the front side of the mounting platform 4. The lens 7 of the camera 6 facilitates real-time inspection of power equipment at different heights and accurate detection of power equipment.

[0037] When the movable buffer component contacts the electrical equipment using the arc plate 25, and the front end of the arc plate 25 contacts the electrical equipment, the impact force of the electrical equipment on the arc plate 25 causes the arc plate 25 to move, and the transparent film 27 prevents the electrical equipment from contacting the lens 7, thereby facilitating the protection of the lens 7, and the lens 7 can detect the electrical equipment through the transparent film 27.

[0038] The impact force causes the arc plate 25 to drive the front slide plate 21 to move backwards by using the connecting frame 30, and the front slide plate 21 uses the screw and nut to make the circular plate 22 move synchronously with the front slide plate 21, and the moving circular plate 22 drives the protrusion 13 on the inner ring 12 to squeeze the spring 15 through the camera 6, and the moving front slide plate 21 drives the rear slide plate 18 to move backward synchronously by using the slide bar 17. When the front slide plate 21 approaches the camera 6, the moving front slide plate 21 uses the connecting frame 30 to push the arc plate 25 to slide inside the annular groove 28, and the moving arc plate 25 cooperates to squeeze the rubber strip 29 inside the annular groove 28, and the moving arc plate 25 drives the transparent film 27 to rotate on the surface of the lens 7, and the rotating transparent film 27 wipes the surface of the lens 7, which is convenient for cleaning the lens 7 and maintaining the clarity of the lens 7.

[0039] The reaction force of the power equipment on the arc plate 25 causes the camera 6 to drive the inner ring 12 to move backward, and the inner ring 12 gradually moves toward the inside of the groove. The moving inner ring 12 slides on the surface of the inner rod 14, and the moving inner ring 12 uses the protrusion 13 to cooperate with the spring 15 on the surface of the inner rod 14, and uses the elastic force of the spring 15 to absorb the impact force between the power equipment and the buffer component, avoiding the impact force directly acting on the surface of the lens 7, thereby facilitating the protection of the lens 7.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
