Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5The present invention provides a technical solution: a solar lighting device for electric power engineering, comprising a first base 1, an inner column 2 and a spotlight 3, wherein the inner column 2 is fixedly connected to the center of the upper end surface of the first base 1, the inner column 2 is a solid cylinder, and sliders are symmetrically arranged on the left and right side walls of the inner column 2, an outer column 4 is sleeved on the outside of the inner column 2, and slide grooves are symmetrically opened on the left and right side inner walls of the outer column 4, and the sliders on the inner column 2 are slidably connected to the slide grooves on the inner walls of the outer column 4, and screw blocks 5 are symmetrically fixedly connected to the left and right side walls of the outer column 4, and screw rods 6 are threadedly connected in the two screw blocks 5, and the thread directions on the surfaces of the two screw rods 6 are the same, and the lower end of the screw rod 6 passes through the first base 1 and is connected to a first bevel gear 7, and a first servo motor 8 is connected to the side wall of the first base 1, and the output of the first servo motor 8 The output shaft end is connected with a long shaft 9, and the long shaft 9 is located in front of the first bevel gear 7. Two second bevel gears 10 are fixedly sleeved on the surface of the long shaft 9. The second bevel gear 10 is engaged with the first bevel gear 7. The first servo motor 8 is started, and the first servo motor 8 drives the two second bevel gears 10 on its surface to rotate through the long shaft 9. The two second bevel gears 10 drive the two first bevel gears 7 to rotate. The two first bevel gears 7 drive the two screw rods 6 to rotate. When the two screw rods 6 rotate, the two screw blocks 5 on their surfaces drive the outer column 4 to perform lifting movements. The upper end of the outer column 4 is rotatably connected with a lamp pole 11, and the upper end of the lamp pole 11 is connected to a spotlight 3. The left and right ends of the lamp pole 11 are symmetrically connected with first pull rope rings 12, and one end of a pull rope 13 is connected to each of the two first pull rope rings 12. The two pull ropes The other end of each of the two bases 13 is connected to a sliding part, which includes a slide 14. The lower end of the slide 14 is symmetrically connected to a first slide rail 15 on both sides. The upper end of the first base 1 is symmetrically provided with a first slideway 16. The first slide rail 15 is slidably connected in the first slideway 16. The upper end of the slide 14 is symmetrically connected to a first vertical plate 17. A short shaft 18 is rotatably connected between the two first vertical plates 17. A winding roller 19 is fixedly sleeved on the surface of the short shaft 18. A second pull rope ring 20 is provided on the surface of the winding roller 19. The other end of the pull rope 13 is connected to the second pull rope ring 20. The front end of the short shaft 18 passes through the first vertical plate 17 and is connected to a first pulley 21. The upper end of the slide 14 is connected to a second servo motor 22. The two sliding parts are controlled by a PLC (programmable logic controller). The two second servo motors 22 have the same rotation speed but opposite directions. The two second servo motors 22 are connected to the same power supply. When one of the motors rotates forward, the other motor rotates reversely, thereby ensuring that the two pull ropes 13 are always in a straight state. One of the second servo motors 22 is started to rotate in one direction, and the other second servo motor 22 rotates in the other direction. The second servo motor 22 drives the first pulley 21 to rotate through the second pulley 23 and the belt 24. The first pulley 21 drives the winding roller 19 to rotate through the short shaft 18, so that the winding roller 19 completes the movement of retracting and releasing the pull rope 13. The pull rope 13 drives the lamp pole 11 to rotate vertically at the upper end of the outer column 4 through the first pull rope ring 12, and the lamp pole 11 drives the spotlight 3 to rotate.Thereby changing the illumination angle of the spotlight 3, the output shaft end of the second servo motor 22 is connected to the second pulley 23, and a belt 24 is connected between the second pulley 23 and the first pulley 21. The surface of the slide 14 on one side close to the outer column 4 is connected to a stretching portion, and the stretching portion includes two first pull rods 25 symmetrically arranged front and back, one end of the two first pull rods 25 is symmetrically rotated front and back and connected to the surface of the slide 14, and the other ends of the two first pull rods 25 are both rotatably connected to one end of the second pull rod 26, and the other ends of the two second pull rods 26 are both rotatably connected to the surface of the outer column 4, and the two second pull rods 26 are symmetrically arranged front and back with the screw 6 as the center. When the block 5 drives the outer column 4 to rise and fall, the second pull rod 26 on the side wall of the outer column 4 drives the slide 14 to move horizontally on the first base 1 through the first pull rod 25, thereby ensuring that the two pull ropes 13 of the spotlight 3 are always in a straight state whether it is rising or falling, thereby ensuring that the irradiation angle of the spotlight 3 remains unchanged, thereby improving the accuracy of the spotlight 3 when irradiating. The surface of the outer column 4 and the fixed sleeve above the screw 6 are provided with a platform 27, and the upper end of the platform 27 is connected to a solar panel 28, and the solar panel 28 is electrically connected to the spotlight 3. The solar panel 28 absorbs solar energy and converts it into electrical energy to power the spotlight 3, which is more energy-saving.

[0019] Specifically, the diameter of the first bevel gear 7 is greater than the diameter of the second bevel gear 10, which reduces the rotation speed of the screw 6, thereby reducing the moving speed of the screw block 5, and then reducing the lifting speed of the outer column 4, avoiding the outer column 4 from lifting too fast and unstable.

[0020] Specifically, the platform 27 is a conical platform, the solar panel 28 is an annular panel, and the left and right sides of the platform 27 are symmetrically connected with guide parts, and the guide parts include two second vertical plates 29 symmetrically arranged front and back, and the first guide wheel 30 and the second guide wheel 31 are rotatably connected between the two second vertical plates 29, and the pull rope 13 passes through the first guide wheel 30 and the second guide wheel 31. By setting the first guide wheel 30 and the second guide wheel 31, the pull rope 13 can be guided. At the same time, the first guide wheel 30 and the second guide wheel 31 can rotate when they come into contact with the pull rope 13, thereby reducing the friction when connected with the pull rope 13, reducing the wear of the pull rope 13, and increasing the service life of the pull rope 13.

[0021] Specifically, a second slide 32 is provided at the upper end of the first base 1 and between the two first slides 16, and a second slide rail 33 is connected to the bottom of the slide 14. The second slide rail 33 is slidably connected in the second slide 32, and a return spring 34 is connected between the side wall of the second slide 32 and the inner wall of the second slide rail 32. When the screw block 5 drives the outer column 4 to descend, the outer column 4 pushes the slide 14 to move to the side away from the outer column 4 through the second pull rod 26 and the first pull rod 25. During the pushing process, the slide 14 is prone to get stuck. The return function of the return spring 34 can provide a pulling force to the slide 14, thereby preventing the slide 14 from getting stuck during the movement. A telescopic rod 35 is provided in the return spring 34, and the service life of the return spring 34 can be increased by setting the telescopic rod 35.

[0022] Specifically, the lower end of the first base 1 is connected to a rotating part, and the rotating part includes a second base 36. The second base 36 is provided with a groove 37. The side wall of the groove 37 is connected to a third servo motor 38. The upper end of the second base 36 is fixedly connected to an outer ring 39. The inner wall of the outer ring 39 is rotatably connected to an inner gear ring 40 through a ball bearing. The outer ring 39, the ball bearing and the inner gear ring 40 form a rotary support structure. The lower end of the outer ring 39 is fixedly connected to the upper end of the second base 36. The upper end of the inner gear ring 41 is fixedly connected to the first base 1. The output shaft end of the third servo motor 38 is connected to a spur gear 41. The spur gear 41 is engaged with the inner gear ring 40. When the third servo motor 38 is started, the third servo motor 38 drives the inner gear ring 39 to rotate through the spur gear 41. The inner gear ring 39 drives the first base 1 to rotate. The first base 1 drives the spotlight 3 to rotate on a horizontal plane through the outer column 4 and the lamp pole 11, thereby changing the irradiation direction of the spotlight 3.

[0023] Working principle: The present invention is a solar lighting device for electric power engineering. The device is moved to a designated working position, and the first servo motor 8 is started. The first servo motor 8 drives the two second bevel gears 10 on its surface to rotate through the long shaft 9. The two second bevel gears 10 drive the two first bevel gears 7 to rotate. The two first bevel gears 7 drive the two screw rods 6 to rotate. When the two screw rods 6 rotate, the two screw blocks 5 on their surfaces drive the outer column 4 to perform lifting and lowering movements. When the outer column 4 is lifted and lowered, the second pull rod 26 on the side wall of the outer column 4 drives the slide 14 to translate on the first base 1 through the first pull rod 25 to ensure that the pull rope 13 is always in a straight state. The two second servo motors 22 on the two sliding parts have the same rotation speed but opposite directions through the PLC (programmable logic controller). The two second servo motors 22 are connected to the same power supply, and one of the second servo motors 22 is started to rotate in one direction, and the other second servo motor 22 rotates in the other direction. The first pulley 21 rotates in one direction, and the second servo motor 22 drives the first pulley 21 to rotate through the second pulley 23 and the belt 24. The first pulley 21 drives the winding roller 19 to rotate through the short shaft 18, so that the winding roller 19 completes the movement of retracting and releasing the pull rope 13. The pull rope 13 drives the lamp pole 11 to rotate in a vertical plane at the upper end of the outer column 4 through the first pull rope ring 12. The lamp pole 11 drives the spotlight 3 to rotate, thereby changing the irradiation angle of the spotlight 3. The third servo motor 38 is started, and the third servo motor 38 drives the inner gear ring 39 to rotate through the spur gear 41. The inner gear ring 39 drives the first base 1 to rotate. The first base 1 drives the spotlight 3 to rotate on the horizontal plane through the outer column 4 and the lamp pole 11, thereby changing the irradiation direction of the spotlight 3 on the horizontal plane. Compared with traditional lighting devices, the irradiation angle, direction and height of the spotlight 3 are all adjustable, which is convenient for people to use, and when the height of the spotlight 3 changes, the height of the entire device also changes accordingly, thereby facilitating people to move the device.
