[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0035] Example 1

[0036] like Figure 1 - Figure 8As shown, the present invention discloses a high-efficiency photovoltaic parallel drive device applied to a photovoltaic tracking system, comprising a device body 1, a mounting base plate 2 is fixedly connected to the back of the device body 1, it should be noted that a plurality of screw holes are provided on the mounting base plate 2, and the device body 1 is fixedly installed through the screw holes on the mounting base plate 2, specifically, a threaded groove that matches the screw holes on the mounting base plate 2 is provided at a position of the mounting surface close to the mounting base plate 2, and then the mounting base plate 2 is installed on the mounting surface by bolts, a transmission box 3 is fixedly connected to the side of the device body 1, a steering mechanism 4 is fixedly connected to the top of the transmission box 3, and a driving mechanism 5 is fixedly connected to the side of the steering mechanism 4, the driving mechanism 5 transmits power to the device body 1 through the steering mechanism 4 and the transmission box 3, when in use, the driving mechanism 5 is first opened, the output shaft of the driving mechanism 5 transmits power to the transmission box 3 through the steering mechanism 4, and the transmission box 3 then transmits power to the device body 1, so that the device body The body 1 completes the steering operation. The device body 1 includes a worm gear 11, a flange 12 is arranged inside the worm gear 11, and a support bearing 14 is arranged on the inner side of the worm gear 11. The support bearing 14 is used to fix the worm gear 11 so that the worm gear 11 rotates stably. An oil chamber 15 is opened on the inner wall of the worm gear 11. A fixing ring 16 is fixedly connected to the side of the flange 12 near the oil chamber 15. An adjusting slide 17 matching the oil chamber 15 is fixedly connected to the side of the fixing ring 16. An automatic calibration mechanism 18 is arranged on the back of the worm gear 11 and the cavity between the mounting base plate 2. It should be noted that when the flange 12 rotates, the flange 12 will drive the fixing ring 16 on its outer side to rotate synchronously. Since the side of the fixing ring 16 is fixedly connected to the adjusting slide 17 matching the oil chamber 15, the rotating fixing ring 16 will drive the adjusting slide 17 to slide inside the oil chamber 15, thereby causing an angle difference between the worm gear 11 and the flange 12. Specifically, when working:

[0037] The flange 12 is directly connected to the photovoltaic panel by bolts to control the direction of the photovoltaic panel so that the photovoltaic panel can follow the direction of the sun's illumination and improve the illumination effect of the photovoltaic panel. When in use, the driving mechanism 5 is first turned on. The output shaft of the driving mechanism 5 transmits power to the transmission box 3 through the steering mechanism 4. The transmission box 3 then transmits power to the device body 1, specifically, the power is transmitted to the worm gear 11, so that the worm gear 11 rotates a certain angle. As the worm gear 11 works for a long time, the transmission between the driving mechanism 5, the steering mechanism 4 and the transmission box 3 will produce fatigue, resulting in the angle of the worm gear 11. If it is not precise enough, the hydraulic oil in the oil chamber 15 can be used to push the adjusting slide 17 to move the adjusting slide 17 to a fixed angle in the oil chamber 15, and the adjusting slide 17 will drive the flange 12 through the fixing ring 16 to move the flange 12 to a fixed angle, while the worm gear 11 will not move at this time. Therefore, the angle of the flange 12 can be further adjusted by adjusting the slide 17, so that the flange 12 can adjust the angle of the photovoltaic panel to the set position, thereby realizing the angle calibration function of the photovoltaic panel and ensuring the accuracy of the high-efficiency photovoltaic parallel drive device in controlling the angle of the photovoltaic panel.

[0038] Example 2

[0039] like Figure 3 As shown, a fixed bearing 31 is provided inside the transmission box 3, and an enveloping worm 32 is installed on the inner side of the fixed bearing 31. The enveloping worm 32 is meshed with the worm wheel 11. The fixed bearing 31 is provided inside the transmission box 3, and the enveloping worm 32 is inserted on the inner side of the fixed bearing 31. When the enveloping worm 32 rotates, since the enveloping worm 32 is meshed with the worm wheel 11, the enveloping worm 32 will drive the worm wheel 11 to rotate.

[0040] like Figure 3 and Figure 4 As shown, a driven bevel gear 41 is arranged inside the steering mechanism 4, and the driving mechanism 5 includes a driving motor 51, and the output end of the driving motor 51 is connected to a planetary reducer 52, and the side of the planetary reducer 52 away from the driving motor 51 is connected to an active bevel gear 53, and the active bevel gear 53 is meshed with the driven bevel gear 41, and the bottom center position of the driven bevel gear 41 is fixedly connected to the top of the enveloping worm 32. It should be noted that the output shaft of the driving motor 51 is connected to the input shaft of the planetary reducer 52, and the output shaft of the planetary reducer 52 is connected to the The active bevel gear 53 is fixedly connected. When in use, the driving motor 51 is turned on, and the power of the driving motor 51 is transmitted to the planetary reducer 52 through the output shaft. The power of the planetary reducer 52 is transmitted to the active bevel gear 53 through the output shaft. Since the active bevel gear 53 is meshed with the driven bevel gear 41, the rotating active bevel gear 53 will drive the driven bevel gear 41 to rotate. Since the bottom center position of the driven bevel gear 41 is fixedly connected to the top of the enveloping worm 32, the rotating driven bevel gear 41 will drive the enveloping worm 32 to rotate synchronously.

[0041] Example 3

[0042] like Figure 6 - Fig.12 As shown, the automatic calibration mechanism 18 includes a movable base plate 181, and an oil tank 182 is fixedly connected to the middle position of the movable base plate 181. A movable piston 183 is arranged inside the oil tank 182, and a piston rod 184 is inserted into the inner side of the movable piston 183. The movable piston 183 divides the oil tank 182 into a first inner cavity 182a and a second inner cavity 182b. The adjusting slide 17 divides the oil chamber 15 into a first cavity 15a and a second cavity 15b. The first inner cavity 182a is connected to the first cavity 15a through an oil pipe, and the second inner cavity 182b is connected to the second cavity 15b through an oil pipe. A sealing ring 13 is connected to the side of the worm gear 11 near the oil chamber 15. The sealing ring 13 is used to seal the oil chamber 15 to prevent the hydraulic oil in the oil chamber 15 from leaking. It should be noted that the movable piston 183 can move in the inner cavity of the oil tank 182 to Fig. 9 For example, when the movable piston 183 moves toward the first inner chamber 182a, the movable piston 183 will compress the hydraulic oil in the first inner chamber 182a. Since the first inner chamber 182a is connected with the first cavity 15a through the oil pipe, and the second inner chamber 182b is connected with the second cavity 15b through the oil pipe, the hydraulic oil in the first inner chamber 182a can enter the first cavity 15a through the oil pipe. At the same time, the second inner chamber 182b will increase, so the second inner chamber 182b will suck the hydraulic oil in the second cavity 15b through the oil pipe. Since the hydraulic oil in the first cavity 15a increases and the hydraulic oil in the second cavity 15b decreases, the adjusting slide 17 will move in the oil chamber 15 toward the second cavity 15b, thereby realizing the automatic movement of the adjusting slide 17. Conversely, when the movable piston 183 moves to the second cavity 15b, the adjusting slide 17 will move in the oil chamber 15 toward the first cavity 15a.

[0043] like Figure 1 - Fig. 9 As shown, one end of the piston rod 184 is connected to an adjustment mechanism 187, and one end of the movable bottom plate 181 away from the adjustment mechanism 187 is fixedly connected to a fixed magnet 185, and an electromagnetic block 186 is provided on the side of the fixed magnet 185 away from the movable bottom plate 181. It should be noted that the magnetic poles generated by the electromagnetic block 186 when energized are the same as the magnetic poles on the fixed magnet 185, so that when the electromagnetic block 186 is energized, the electromagnetic block 186 will generate a magnetic repulsion force with the fixed magnet 185, and the electromagnetic block 186 is fixed to the inner side of the device body 1, while the movable bottom plate 181 is movable on the inner side of the device body 1. It should be noted that a movable groove that matches the movable bottom plate 181 can be opened at a position close to the movable bottom plate 181 on the inner side of the device body 1, so as to ensure that the movable bottom plate 181 can slide stably in the movable groove;

[0044] like Figure 1 - Fig. 9 As shown, the electromagnetic block 186 is fixed inside the device body 1, and barbs are arranged on both sides of the electromagnetic block 186. The barbs are used to limit the moving distance of the movable base plate 181. A spring is also arranged on the inner side of the barb. When the electromagnetic block 186 is energized, the electromagnetic block 186 will generate a magnetic repulsion force with the fixed magnet 185, so that the fixed magnet 185 drives the movable base plate 181 to move to the side away from the electromagnetic block 186, and when moving, the fixed magnet 185 will overcome the elastic force of the spring. When the electromagnetic block 186 is disconnected from the power supply, the electromagnetic block 186 will not generate a magnetic repulsion force with the fixed magnet 185. At this time, the elastic force of the spring will act on the fixed magnet 185, so that the fixed magnet 185 drives the movable base plate 181 to move to one side of the electromagnetic block 186, so that the movable base plate 181 automatically returns to its position.

[0045] like Fig. 9 and Fig.10 As shown, the adjusting mechanism 187 includes an adjusting wheel 1871, the inner side of which is rotatably connected to an adjusting rod 1872, and one end of the adjusting rod 1872 away from the adjusting wheel 1871 is rotatably connected to the piston rod 184. When the adjusting wheel 1871 rotates, the adjusting wheel 1871 drives the piston rod 184 to move through the adjusting rod 1872, and the piston rod 184 drives the moving piston 183 in the inner cavity of the oil tank 182 to move. Therefore, the movement of the moving piston 183 can be controlled by the rotation of the adjusting wheel 1871.

[0046] like Fig. 9 - Fig.12 as well as Fig.15 As shown, a moving cavity 1873 is provided inside the top of the adjusting wheel 1871, and a moving gear ring 1874 is provided inside the moving cavity 1873. An adjusting tooth 111 matching the moving gear ring 1874 is fixedly connected to the back of the worm gear 11 near the moving gear ring 1874. An oil cylinder 1875 is installed inside the adjusting wheel 1871, and the output end of the oil cylinder 1875 is connected to the moving cavity 1873. It should be noted that the oil pipe between the first inner cavity 182a and the first cavity 15a and the oil pipe between the second inner cavity 182b and the second cavity 15b The tube passes through the movable chamber 1873. When the oil cylinder 1875 sucks the hydraulic oil in the movable chamber 1873, the movable ring gear 1874 will move toward the inside of the movable chamber 1873 and squeeze the oil pipe to seal the oil pipe. When the oil cylinder 1875 discharges the hydraulic oil into the movable chamber 1873, the hydraulic oil entering the movable chamber 1873 will support the movable ring gear 1874. At the same time, the movable ring gear 1874 will break away from the squeezed oil pipe, so that the first inner chamber 182a is connected to the first cavity 15a, and the second inner chamber 182b is connected to the second cavity 15b.

[0047] In the actual operation process, the driving motor 51 is turned on first, and the power of the driving motor 51 is transmitted to the planetary reducer 52 through the output shaft, and the power of the planetary reducer 52 is transmitted to the active bevel gear 53 through the output shaft. Since the active bevel gear 53 is meshed with the driven bevel gear 41, the rotating active bevel gear 53 will drive the driven bevel gear 41 to rotate. Since the bottom center position of the driven bevel gear 41 is fixedly connected to the top of the enveloping worm 32, the rotating driven bevel gear 41 will drive the enveloping worm 32 to rotate synchronously, and the rotating enveloping worm 32 will drive the worm wheel 11 to rotate. At this time, the oil cylinder 1875 sucks the hydraulic oil in the moving chamber 1873 to move the moving ring gear 1874 to the moving chamber 1873. The inner side of the cavity 1873 moves and squeezes on the oil pipe to seal the oil pipe, so that there will be no relative movement between the worm gear 11 and the flange 12. The rotation angle of the worm gear 11 is the rotation angle of the flange 12. When the backstage personnel find that the rotation angle of the photovoltaic panel connected to the flange 12 deviates through monitoring or other means, for example, the photovoltaic panel cannot reach the required rotation angle, that is, when the photovoltaic panel is driven by the worm gear 11 and the flange 12, the steering angle of the photovoltaic panel is small. Taking the clockwise rotation of the worm gear 11 as an example, when the clockwise rotation of the worm gear 11 is completed, the flange 12 needs to continue to rotate clockwise by a certain angle to ensure that the steering angle of the photovoltaic panel is restored to the preset level. Specifically, follow the following steps:

[0048] First, the steering angle R0 and steering time t of each adjustment of the worm gear 11 are obtained, and the steering angle per unit time of the worm gear 11 can be obtained as R0 / t. The backstage personnel then obtain the smaller steering angle of the photovoltaic panel through monitoring or other means. For example, the smaller steering angle of the photovoltaic panel is obtained as R1, and the adjustment time of the flange 12 based on the rotation speed of the worm gear 11 can be obtained as (R1 / R0)×t;

[0049] During the next adjustment of the worm gear 11, when the adjustment time of the worm gear 11 reaches t-(R1 / R0)×t, the oil cylinder 1875 is opened to inject hydraulic oil into the moving chamber 1873, so that the moving ring gear 1874 will move outward under the action of the hydraulic oil and mesh with the adjusting tooth 111 on the worm gear 11. When the moving ring gear 1874 meshes with the adjusting tooth 111, the rotating worm gear 11 will drive the adjusting wheel 1871 to rotate through the moving ring gear 1874, and the rotating adjusting wheel 1871 will drive the piston rod 184 to move through the adjusting rod 1872, and the piston The rod 184 will drive the movable piston 183 in the inner cavity of the oil tank 182 to move. Since the flange 12 needs to continue to rotate clockwise, it is necessary to adjust the slide 17 to move toward the first cavity 15a in the oil cavity 15, that is, the movable piston 183 moves toward the second inner cavity 182b. The rotation time of the flange 12 relative to the worm gear 11 is (R1 / R0)×t, and the rotation angle is R1, that is, when the worm gear 11 completes the rotation of R0, the rotation angle of the flange 12 relative to the worm gear 11 is R1, so that the smaller angle of the photovoltaic panel can be restored to make the steering angle of the photovoltaic panel at the set value;

[0050] When the worm wheel 11 completes its rotation, the oil cylinder 1875 draws hydraulic oil from the moving chamber 1873, causing the moving gear ring 1874 to move toward the inside of the moving chamber 1873, and at the same time squeezes the oil pipe to seal the oil pipe, so that the relative position between the worm wheel 11 and the flange 12 is also locked;

[0051] When the steering angle of the photovoltaic panel is too large, for example, the steering angle of the photovoltaic panel is too large by an angle R1, then when the worm gear 11 completes the clockwise rotation, the flange 12 needs to rotate counterclockwise to offset the large steering angle of the photovoltaic panel, so as to ensure the accuracy of the steering angle of the photovoltaic panel. Unlike the clockwise adjustment of the flange 12, it is necessary to open the oil cylinder 1875 and inject hydraulic oil into the moving chamber 1873 while connecting the circuit of the electromagnetic block 186, so that the electromagnetic block 186 generates a magnetic field, and the electromagnetic block 186 will generate a magnetic repulsion force with the fixed magnet 185, so that the fixed magnet 185 drives the moving base plate 181 to move to the side away from the electromagnetic block 186, and when moving, the fixed magnet 185 will overcome the elastic force of the spring, such as Fig.13 and Fig.14 As shown, the meshing state of the movable gear ring 1874 and the adjusting tooth 111 changes, that is, the center of the movable gear ring 1874 is adjusted from the inner side of the adjusting tooth 111 to the outer side of the adjusting tooth 111, so that Fig.13 and Fig.14 Taking the adjusting tooth 111 in the embodiment as an example, when the adjusting tooth 111 rotates counterclockwise, Fig.13 The adjusting tooth 111 will drive the moving gear ring 1874 to rotate counterclockwise synchronously, and Fig.14When the adjusting tooth 111 in the middle rotates counterclockwise, the adjusting tooth 111 will make the mobile gear ring 1874 rotate clockwise, so that the adjusting tooth 111 drives the mobile gear ring 1874 to rotate in the opposite direction, and the direction of rotation of the adjusting wheel 1871 will also be opposite. At this time, the mobile piston 183 moves toward the first inner cavity 182a. When the mobile piston 183 moves toward the first inner cavity 182a, the mobile piston 183 compresses the hydraulic oil in the first inner cavity 182a. Since the first inner cavity 182a is connected to the first cavity 15a through the oil pipe, the second inner cavity 182b is connected to the second inner cavity 182b through the oil pipe. The two cavities 15b are interconnected, so the hydraulic oil in the first inner cavity 182a can enter the first cavity 15a through the oil pipe. At the same time, the second inner cavity 182b will increase, so the second inner cavity 182b will suck the hydraulic oil in the second cavity 15b through the oil pipe. Since the hydraulic oil in the first cavity 15a increases and the hydraulic oil in the second cavity 15b decreases, the adjusting slide 17 will move in the oil cavity 15 toward the second cavity 15b, that is, the flange 12 will rotate counterclockwise to offset the large steering angle of the photovoltaic panel and restore the steering angle of the photovoltaic panel to a normal value.

[0052] It should also be noted that pressure sensors are installed at the middle positions on both sides of the adjusting slide 17. The two pressure sensors are used to collect the pressure value between the adjusting slide 17 and the inner wall of the oil chamber 15. When the adjusting slide 17 contacts the inner wall of the first cavity 15a, the reading of the pressure sensor on the side of the adjusting slide 17 close to the first cavity 15a will change, indicating that the adjustment amplitude of the adjusting slide 17 has reached the highest state. At this time, the rotation of the worm gear 11 can be calibrated. The calibration range is to move the adjusting slide 17 back to the middle position of the oil chamber 15. Specifically, taking the case where the adjusting slide 17 contacts the inner wall of the first cavity 15a as an example, the worm gear 11 is calibrated in the following manner:

[0053] At the same time, the circuits of the drive motor 51, the cylinder 1875 and the electromagnetic block 186 are turned on. The drive motor 51 causes the worm wheel 11 to continue to rotate clockwise through the enveloping worm 32, and causes the flange 12 to rotate counterclockwise. When the worm wheel 11 completes its rotation, the time t1 when the worm wheel 11 completes its rotation is recorded. The rotation time of the worm wheel 11 in the next cycle is t+t1.

[0054] When the adjusting slide 17 contacts the inner wall of the second cavity 15b, the calibration of the worm gear 11 is performed in the following manner:

[0055] At the same time, the circuits of the drive motor 51, the cylinder 1875 and the electromagnetic block 186 are turned on. The drive motor 51 causes the worm wheel 11 to continue to rotate counterclockwise through the enveloping worm 32, while causing the flange 12 to rotate clockwise. When the worm wheel 11 completes rotation, the time t2 when the worm wheel 11 completes rotation is recorded. The rotation time of the worm wheel 11 in the next cycle is t-t2.
