[0004] However, the device adopts a fixed method for the installation of lightning rods. When used in thunderstorms, the lightning rods lack the corresponding buffer structure and directly confront the wind force. As the use time increases, the lightning rods will bend, thus affecting the use effect of the lightning rods.

[0005] Therefore, it is necessary to provide a 5G antenna base station lightning protection device to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a 5G antenna base station lightning protection device to solve the existing problems in the above-mentioned background technology.

After the driving device drives the external rods and internal rods on the four sides of the lightning rod to fix each other, the lightning rod can no longer deflect and is in a fixed state relative to the bottom plate. Since the driving device drives the four lower connecting rods and the upper connecting rod to rotate at the same time, the length of the sleeve driven by the screw thread with the external rod is equal, so that the lightning rod is in a vertical state after fixation and will not deflect to one side, which is conducive to the normal use of the lightning rod.

[0011] As a further solution of the present invention, a through ball groove is provided at the center position of the top of the base plate, and the bottom of the lightning rod is connected to the inside of the ball groove in a ball joint manner.

[0012] During specific use, the bottom of the lightning rod arranged on the top of the base plate is connected to the inside of the ball groove in the form of a ball joint, so that the lightning rod can rotate freely at the bottom of the base plate.

[0013] As a further solution of the present invention, the outer bottom end of the connecting piece is fixedly connected to a limiting block, which is slidably connected to the inside of a groove on the bottom plate.

The front and rear sides of the limiting block are fixedly connected to guide blocks, and the guide blocks are slidably connected to the inside of the guide grooves.

[0014] During specific use, the guide block is slidably connected to the inside of the guide groove. The guide groove is arc-shaped, and its center coincides with the center of the limit block, so that the limit block can drive the guide block to rotate inside the guide groove. Through this mechanism, the rotation of the limit block inside the groove can be further limited, and the stability of the rotation of the limit block can be further improved, thereby improving the stability of the rotation of the connecting piece.

[0015] As a further solution of the present invention, the connecting member includes an upper connecting rod and a lower connecting rod, a slider is fixedly connected to the outer wall of the upper connecting rod, and a sliding groove is opened on the inner wall of the lower connecting rod, the slider is slidably connected to the inside of the sliding groove, the top end of the upper connecting rod is fixed to the inner top wall of the sleeve, the lower connecting rod passes through the external connecting rod and extends to the outside of the external connecting rod, and the limit block is fixedly connected to the outside of the lower connecting rod.

[0016] During specific use, the cooperation between the slider and the slide groove enables the lower connecting rod to rotate, thereby driving the upper connecting rod to rotate. During the rotation, the upper connecting rod and the lower connecting rod can slide relative to each other.

[0017] As a further solution of the present invention, the driving device includes a motor, the output end of the motor is fixedly connected to a transmission shaft, the output end of the transmission shaft is fixedly connected to a driving gear, the outer side of the driving gear is meshed with a gear ring, the outer side of the gear ring is rotatably connected to a rotating seat, and the rotating seat is fixedly connected to the bottom of the base plate.

[0019] During specific use, the output end of the motor can drive the driving gear to rotate, the driving gear can drive the ring gear to rotate, and then the ring gear can drive the driven gear to rotate, the driven gear can drive the universal joint to rotate, and the universal joint can be used to drive the lower connecting rod to rotate, and then the upper connecting rod can be driven to rotate, which can drive the sleeve to rotate. This mechanism drives the lower connecting rod to rotate through the universal joint. Even if the lightning rod is deflected, the deflected lower connecting rod can also be driven to rotate through the universal joint, thereby completing the adjustment of the lightning rod to make it in a vertical state.

[0020] As a further solution of the present invention, a lead is provided at the bottom of the lightning rod, and the lead is used to connect to a grounding device.

[0021] As a further solution of the present invention, the top of the bottom plate is fixedly connected to a connecting seat on both sides of the groove by bolts, and the external rod is hinged to the connecting seat through circular axes on its front and rear sides.

[0022] During specific use, the connecting seat facilitates the ball joint between the lightning rod and the bottom plate.

[0023] 1. A 5G antenna base station lightning protection device described in the present invention can squeeze the spring inside the left external rod when the wind blows the lightning rod to deflect to the left, which can play a buffering role, thereby protecting the lightning rod. Traditional lightning rods generally adopt a fixed connection method. In windy weather, the lightning rod resists the wind force, making the lightning rod easy to bend, thereby affecting the use of the lightning rod. This structure can protect the lightning rod by arranging springs in the front, back, left and right of the lightning rod.

[0024] 2. When the sleeve rotates and moves downward, it will gradually contact the external rod. Since the sleeve and the external rod are threadedly connected, when the sleeve moves downward and contacts the external rod, it will gradually be threadedly connected with the external rod. When the sleeve is threadedly connected with the external rod, the external rod, the sleeve and the internal rod are in a relatively fixed state. At this time, the internal rod cannot slide downward relative to the external rod, thereby avoiding deflection of the lightning rod. Since external rods and internal rods are provided on the four sides of the outside of the lightning rod, when the driving device drives the external rods and the internal rods on the four sides of the lightning rod to be fixed to each other, the lightning rod cannot be deflected and is fixed relative to the bottom plate. Since the driving device drives the four lower connecting rods and the upper connecting rod to rotate at the same time, the length of the sleeve driving the threaded engagement with the external rod is equal, so that the lightning rod is in a vertical state after fixation and will not deflect to one side, which is beneficial to the normal use of the lightning rod.

DETAILED DESCRIPTION

[0037] like Figure 1-10 As shown, a 5G antenna base station lightning protection device includes a base plate 1 and a connecting column 13 fixedly connected to the bottom of the base plate 1. The connecting column 13 is used to facilitate the installation of the entire device on an external device. A through ball groove 4 is provided at the center of the top of the base plate 1. The bottom of the lightning rod 6 provided on the top of the base plate 1 is connected to the inside of the ball groove 4 in a ball joint manner, so that the lightning rod 6 can rotate freely at the bottom of the base plate 1.

[0038] Furthermore, a connecting block 7 is fixedly connected to the top of the outer side of the lightning rod 6, an inner connecting rod 8 is arranged on the outer side of the connecting block 7, a hinge head 22 is arranged on the top of the inner connecting rod 8, and a slot is opened on the outer side of the connecting block 7, the hinge head 22 is hinged to the inside of the slot through a pin shaft, so that the inner connecting rod 8 can rotate around the pin shaft inside the slot, and a sleeve 5 is arranged at the bottom end of the inner connecting rod 8, a sleeve rod 9 is fixedly connected to the top of the sleeve 5, the bottom end of the inner connecting rod 8 extends to the inside of the sleeve rod 9 and is threadedly connected to the sleeve rod 9, and an inner cylinder 28 is also fixedly connected to the inside of the sleeve 5. A slide rod 21 is provided inside the inner cylinder 28, and the top end of the slide rod 21 extends into the inner cylinder 28 and is rotatably connected to the inner cylinder 28 through a tapered roller bearing. An external rod 10 is provided at the bottom end of the sleeve 5, and an external thread is provided on the outer side of the external rod 10. An internal thread meshing with the external thread is provided on the inner wall of the sleeve 5, so that the sleeve 5 can be threadedly connected to the outer side of the external rod 10, and the slide rod 21 can be slidably connected to the inside of the external rod 10. A cavity is provided inside the external rod 10, and a spring 27 is provided inside the cavity. The spring 27 is placed at the bottom end of the slide rod 21.

[0039] Furthermore, a through groove 3 is provided on the top of the base plate 1, and the bottom end of the lower connecting rod 26 passes through the groove 3, and a connecting seat 2 is fixedly connected to the top of the base plate 1 on both sides of the groove 3 by bolts, and the external rod 10 is hinged to the connecting seat 2 through the circular axis on its front and rear sides, so that the external rod 10 can rotate around the circular axis.

[0040] A connecting piece 20 is provided inside the sleeve 5. The connecting piece 20 is a rod. The top end of the connecting piece 20 is fixed to the top wall inside the sleeve 5. The bottom end of the connecting piece 20 extends downward through the sliding rod 21, the spring 27 and the external rod 10 and extends to the outside of the external rod 10. The outer bottom end of the connecting piece 20 is fixedly connected to a limiting block 11. The limiting block 11 is slidably connected to the inside of the groove 3. The limiting block 11 is set to an arc shape, and its center of circle coincides with the center line of the circular axis, so that the limiting block 11 also rotates around the circular axis. This structure is conducive to synchronously driving the limiting block 11 to rotate inside the groove 3 when the external rod 10 rotates, which is conducive to improving the stability of the connecting piece 20 rotating with the external rod 10 and improving the structural strength of the connecting piece 20.

[0041] In addition, guide grooves 32 are provided on the front and rear sides of the groove 3, and guide blocks 19 are fixedly connected on the front and rear sides of the limit block 11. The guide block 19 is slidably connected to the inside of the guide groove 32. The guide groove 32 is arc-shaped, and its center coincides with the center of the limit block 11, so that the limit block 11 can drive the guide block 19 to rotate inside the guide groove 32. Through this mechanism, the rotation of the limit block 11 inside the groove 3 can be further limited, and the stability of the rotation of the limit block 11 can be further improved, thereby improving the stability of the rotation of the connecting member 20.

[0042] Furthermore, the connecting member 20 includes an upper connecting rod 24 and a lower connecting rod 26. A slider 23 is fixedly connected to the outer side wall of the upper connecting rod 24, and a slide groove 25 is provided on the inner side wall of the lower connecting rod 26. The slider 23 is slidably connected to the inside of the slide groove 25. Through the cooperation between the slider 23 and the slide groove 25, the rotation of the lower connecting rod 26 can drive the upper connecting rod 24 to rotate, and while rotating, the upper connecting rod 24 and the lower connecting rod 26 can slide relative to each other. The top end of the upper connecting rod 24 is fixed to the inner top wall of the sleeve 5, the lower connecting rod 26 passes through the external connecting rod 10 and extends to the outside of the external connecting rod 10, and the limit block 11 is fixedly connected to the outside of the lower connecting rod 26. A driving device that can drive the lower connecting rod 26 to rotate is also provided at the bottom of the base plate 1.

[0043] When in use, since the ball at the bottom end of the lightning rod 6 is hinged in the ball groove 4, in windy weather, the wind can blow the lightning rod 6 to swing, and the lightning rod 6 can move horizontally in the left and right and front and back directions. When the lightning rod 6 is blown by the wind to move in the left and right directions, the hinge head 22 on the left side of the connecting block 7 can be pressurized, thereby squeezing the inner connecting rod 8, and the inner connecting rod 8 is threadedly connected to the sleeve rod 9, so the sleeve rod 9 can be pressed downward by the inner connecting rod 8. Since the sleeve rod 9 is fixed to the sleeve 5, the sleeve 5 can be pressed downward by the sleeve rod 9. The inner cylinder 28 fixedly connected inside the sleeve 5 is rotatably connected to the sliding rod 21 through a tapered roller bearing. Therefore, through The sleeve 5 can drive the slide rod 21 to slide inside the external rod 10 and squeeze the spring 27. The compression of the spring 27 can play a role of buffering and shock absorption. Therefore, it can be seen from the above description that when the wind blows the lightning rod 6 to deflect to the left, the spring 27 inside the left external rod 10 can be squeezed, which can play a buffering role, thereby protecting the lightning rod 6. Traditional lightning rods 6 generally adopt a fixed connection method. In windy weather, the lightning rod 6 resists the wind force, making the lightning rod 6 easy to bend, thereby affecting the use of the lightning rod 6. This structure can protect the lightning rod 6 by arranging springs 27 on the front, back, left and right sides of the lightning rod 6.

[0044] When it rains, the driving device can drive the lower connecting rod 26 to rotate, and the lower connecting rod 26 can drive the upper connecting rod 24 to rotate through the cooperation of the slider 23 and the slide groove 25, and the upper connecting rod 24 can drive the sleeve 5 to rotate. The sleeve 5 is threadedly connected to the inner connecting rod 8, and the inner connecting rod 8 is hinged to the connecting block 7 through the hinge head 22. Therefore, when the sleeve 5 is driven to rotate through the cooperation of the upper connecting rod 24 and the lower connecting rod 26, the threaded cooperation of the sleeve 5 and the inner connecting rod 8 can drive the sleeve 5 to move downward along the inner connecting rod 8, and when the sleeve 5 moves downward, it can squeeze the upper connecting rod 24, so that the upper connecting rod 24 slides along the outer side of the lower connecting rod 26. This structure can avoid interference between the sleeve 5 and the connecting piece 20 when it moves downward, so that the sleeve 5 can move downward smoothly. When the sleeve 5 rotates and moves downward, it will gradually contact the outer connecting rod 10. Since the sleeve 5 is threadedly connected to the outer connecting rod 10 When the sleeve 5 moves downward and contacts the external rod 10, it will gradually be threadedly connected with the external rod 10. After the sleeve 5 is threadedly connected with the external rod 10, the external rod 10, the sleeve 5 and the internal rod 8 are in a relatively fixed state. At this time, the internal rod 8 cannot slide downward relative to the external rod 10, thereby avoiding the deflection of the lightning rod 6. Since the external rods 10 and the internal rods 8 are arranged on the four sides of the outside of the lightning rod 6, when the driving device drives the external rods 10 and the internal rods 8 on the four sides of the lightning rod 6 to be fixed to each other, the lightning rod 6 cannot be deflected and is in a fixed state relative to the bottom plate 1. Since the driving device drives the four lower connecting rods 26 and the upper connecting rod 24 to rotate at the same time, the length of the sleeve 5 driving the threaded connection with the external rod 10 is equal, so that the lightning rod 6 is in a vertical state after being fixed and will not deflect to one side, which is conducive to the normal use of the lightning rod 6.

[0045] Furthermore, in order to improve the stability of the lightning rod 6 after it is fixed, a contraction portion 31 is provided on the outer side of the inner connecting rod 8. The diameter of the contraction portion 31 is smaller than the diameter of the inner connecting rod 8. A second limiting ring 30 is fixedly connected to the contraction portion 31 on the inner wall of the sleeve rod 9, and a first limiting ring 29 is fixedly connected to the bottom end of the outer side of the contraction portion 31.

[0046] When in use, when the sleeve 5 drives the sleeve rod 9 to rotate, so that it cooperates with the inner connecting rod 8 threadedly to drive the sleeve rod 9 to move downward, the second limiting ring 30 gradually approaches the first limiting ring 29. After the sleeve 5 is threadedly engaged with the outer connecting rod 10 for a certain length, the second limiting ring 30 contacts the first limiting ring 29. At this time, when the sleeve 5 continues to move downward along the outer connecting rod 10, the second limiting ring 30 and the first limiting ring 29 are squeezed, thereby generating an extrusion force between the inner connecting rod 8 and the sleeve rod 9, and then pulling the outer connecting rod 10 through the sleeve 5, so that the inner connecting rod 8 and the outer connecting rod 10 indirectly generate relative The pulling force is conducive to the mutual tension between the inner connecting rod 8 and the outer connecting rod 10. Therefore, the outer connecting rod 10 will generate a pulling force on the lightning rod 6 through the inner connecting rod 8, and the outer connecting rod 10 and the inner connecting rod 8 are arranged on the four sides of the lightning rod 6, so that the pulling force is generated on the four sides of the lightning rod 6 at the same time. Since the driving device drives the sleeve 5 to move downward at the same time, the pulling force generated on the four sides of the lightning rod 6 is the same. This mechanism can tighten the lightning rod 6 on the four sides of the lightning rod 6 at the same time, which can maintain the verticality of the lightning rod 6 on the one hand, and increase the stability of the lightning rod 6 on the other hand, which is conducive to improving the use effect of the lightning rod 6.

[0047] like Figure 1-2 As shown, the driving device includes a motor 12, the output end of the motor 12 is fixedly connected to a transmission shaft, the output end of the transmission shaft is fixedly connected to a driving gear 33, the outer side of the driving gear 33 is meshed with a ring gear 17, the outer side of the ring gear 17 is rotatably connected to a rotating seat 18, the rotating seat 18 is fixedly connected to the bottom of the base plate 1, the inner side of the ring gear 17 is meshed with a driven gear 15, the bottom end of the driven gear 15 is provided with a vertical shaft for mounting and supporting it, the top of the driven gear 15 is connected to a universal joint 16, and the bottom end of the lower connecting rod 26 is connected to the universal joint 16.

[0048] When in use, in thunderstorm weather, the output end of the motor 12 can drive the driving gear 33 to rotate, and the driving gear 33 can drive the ring gear 17 to rotate, and then drive the driven gear 15 to rotate through the ring gear 17, and the driven gear 15 can drive the universal joint 16 to rotate. The universal joint 16 can drive the lower connecting rod 26 to rotate, and then drive the upper connecting rod 24 to rotate, which can drive the sleeve 5 to rotate. This mechanism drives the lower connecting rod 26 to rotate through the universal joint 16. Even if the lightning rod 6 is in deflection, the deflected lower connecting rod 26 can also be driven to rotate through the universal joint 16, and then the lightning rod 6 can be adjusted to a vertical state.

[0049] The lead wire 14 at the bottom of the lightning rod 6 is used to connect to the grounding device.

[0050] Working principle: the sleeve 5 can be pressed downward by the sleeve rod 9, and the inner cylinder 28 fixedly connected inside the sleeve 5 is rotatably connected to the slide rod 21 through a tapered roller bearing. Therefore, the sleeve 5 can drive the slide rod 21 to slide inside the external rod 10 and squeeze the spring 27. The compression of the spring 27 can play a role of buffering and shock absorption. Therefore, it can be seen from the above description that when the wind blows the lightning rod 6 to deflect to the left, the spring 27 inside the left external rod 10 can be squeezed, which can play a buffering role, thereby protecting the lightning rod 6. Traditional lightning rods 6 generally adopt a fixed connection method. Strong winds and lightning rods 6 resist wind force, making lightning rods 6 easy to bend, thereby affecting the use of lightning rods 6. This structure can protect lightning rods 6 by arranging springs 27 on the front, back, left and right sides of lightning rods 6. When the sleeve 5 moves downward, When the outer rod 10 is moved and contacts with the outer rod 10, it will gradually be threadedly connected with the outer rod 10. When the sleeve 5 is threadedly connected with the outer rod 10, the outer rod 10, the sleeve 5 and the inner rod 8 are in a relatively fixed state. At this time, the inner rod 8 cannot slide downward relative to the outer rod 10, thereby avoiding the deflection of the lightning rod 6. Since the outer rods 10 and the inner rods 8 are arranged on the four sides of the outer part of the lightning rod 6, when the driving device drives the outer rods 10 and the inner rods 8 on the four sides of the lightning rod 6 to be fixed to each other, the lightning rod 6 can no longer deflect and is in a fixed state relative to the bottom plate 1. Since the driving device drives the four lower connecting rods 26 and the upper connecting rod 24 to rotate at the same time, the sleeve 5 drives the length of the threaded engagement with the external rod 10 to be equal, so that the lightning rod 6 is in a vertical state after being fixed and will not deflect to one side, which is conducive to the normal use of the lightning rod 6.
