[0027] Reference Figs. 1-3 For an embodiment of the present application, a kind of power line all-around lightning protection device is provided, comprising: support unit 100 and lightning protection unit 200;

[0028] Wherein, support unit 100 includes support plate 101 and two insulator strings 102 fixedly connected at the top of support plate 101, the top of two insulator strings 102 is fixedly connected with ball head hanging ring 103, the inside of two ball head hanging rings 103 is all through with power line, the side of support plate 101 is fixedly connected with fixed plate 104, the side of fixed plate 104 is fixedly connected with semicircular plate 105 by bolt;

[0029] Lightning protection unit 200 includes T-shaped cylinder 201 fixedly connected at the top of support plate 101, multiple limiting grooves 202 are formed at the top of T-shaped cylinder 201, the inner wall of each limiting groove 202 is rotatably connected with deflection plate 203, the top of each deflection plate 203 is fixedly connected with rectangular plate 204, the top of each rectangular plate 204 is fixedly connected with side lightning rod 205, T-shaped cylinder 201 is provided with T-shaped rod 206 at the top, T-shaped rod 206 is fixedly connected with main lightning rod 207 at the top, the side of each side lightning rod 205 and main lightning rod 207 is fixedly connected with connecting line 208 penetrating support plate 101, lightning protection unit 200 further includes drive assembly 209 for driving side lightning rod 205 to deflect.

[0030] Specifically, the driving assembly 209 includes an electric telescopic rod 2091 fixedly installed at the top of the support plate 101, an output end of the electric telescopic rod 2091 is fixedly connected with a lifting disc 2092 located in the inner cavity of the T-shaped cylinder 201, the top of the lifting disc 2092 is fixedly connected with the T-shaped rod 206, and the top of the lifting disc 2092 is fixedly connected with a plurality of connecting blocks 2093. Each deflection plate 203 is hingedly connected with a connecting plate 2094 in common with a corresponding connecting block 2093.

[0031] The support plate 101 can be fixed on the antenna rod through the fixing plate 104 and the semicircular plate 105, the insulator string 102 suspends the power line through the ball head hanging ring 103, so that the wire is insulated from the antenna rod and the ground, the deflection plate 203 can be deflected in the limiting groove 202, the electric telescopic rod 2091 is located in the T-shaped cylinder 201, and the electric telescopic rod 2091 is used to drive the lifting disc 2092 to lift, the deflection plate 203 is arranged in an L shape, when all-around lightning protection is needed, the lifting disc 2092 is driven to rise by the electric telescopic rod 2091, the bottom of the connecting plate 2094 is deflected through the connecting block 2093, in the process of rising of the lifting disc 2092, the connecting plate 2094 pushes the deflection plate 203 upwards, so that one end of the deflection plate 203 connected with the rectangular plate 204 is deflected away from the main lightning rod 207, and the side lightning rod 205 is deflected through the rectangular plate 204, and all the side lightning rods 205 are deflected to an unfolded state through the plurality of connecting plates 2094.

[0032] At this time, the plurality of side lightning rods 205 are unfolded at equal distances with the main lightning rod 207 as the center line, and the plurality of side lightning rods 205 are in an inclined state, so that all-around lightning protection can be realized through the plurality of side lightning rods 205 and the main lightning rod 207, so that lightning can be hit by at least one of the side lightning rods 205 or the main lightning rod 207, and the connecting lines 208 of the side lightning rods 205 and the main lightning rod 207 are connected with the grounding wire to guide the lightning into the ground, thereby achieving the lightning protection effect, when not in use, the lifting disc 2092 is lowered through the electric telescopic rod 2091, at this time, the connecting plate 2094 pulls the deflection plate 203 downwards, so that one end of the deflection plate 203 connected with the rectangular plate 204 is deflected towards the main lightning rod 207.

[0033] When the plurality of side lightning rods 205 are in a vertical state, the lifting disc 2092 stops moving, at this time, the plurality of side lightning rods 205 are closely close to the main lightning rod 207, and form a stable whole, so that the gravity centers of the plurality of side lightning rods 205 and the main lightning rod 207 are concentrated together in non-lightning weather, thereby effectively ensuring the stability and safety of the overall structure in a strong wind environment.

[0034] Specifically, a plurality of round holes are formed in the top of the lifting disc 2092, the inner wall of the T-shaped cylinder 201 is fixedly connected with a disc 210, the output end of the electric telescopic rod 2091 penetrates through the disc 210, and one side of the T-shaped cylinder 201 is fixedly connected with a drain pipe 211.

[0035] However, when rainwater enters the T-shaped cylinder 201, the rainwater on the lifting disc 2092 can pass through the lifting disc 2092 through the round holes, and then the rainwater drops on the disc 210. The upper end of the drain pipe 211 is flush with the top of the disc 210, so that the rainwater on the disc 210 is discharged through the drain pipe 211, thereby avoiding the accumulation of rainwater in the T-shaped cylinder 201.

[0036] Further, the side wall of the T-shaped rod 206 is fixedly connected with a plurality of limiting blocks 212 distributed in a ring shape. One side of each limiting block 212 is provided with a semicircular notch matching the side lightning rod 205.

[0037] The limiting block 212 is used for limiting the side lightning rod 205. The distribution positions of the plurality of limiting blocks 212 correspond to the distribution positions of the plurality of side lightning rods 205. When the plurality of side lightning rods 205 are deflected to the vertical state, the side lightning rod 205 is deflected to the semicircular notch of the limiting block 212. The limiting block 212 can provide protection for the side lightning rod 205 to ensure that the side lightning rod 205 can remain stable in a strong wind environment, thereby reducing the damage of wind factors to the side lightning rod 205.

[0038] Still further, the outer wall of the T-shaped cylinder 201 is fixedly connected with a plurality of rectangular frames 213 distributed in a ring shape. The plurality of connecting lines 208 respectively penetrate through the corresponding rectangular frames 213. The inner wall of each rectangular frame 213 is fixedly connected with a rubber sleeve 214. The top and bottom of the rubber sleeve 214 protrude from the top and bottom of the rectangular frame 213, respectively.

[0039] The connecting lines 208 of the side lightning rod 205 and the main lightning rod 207 all penetrate through the rectangular frame 213. The rectangular frame 213 is used for limiting the connecting line 208, so that the plurality of connecting lines 208 will not be wound together during the deflection of the side lightning rod 205. The rubber sleeve 214 is used for providing flexible protection for the connecting line 208 to avoid the mutual friction between the connecting line and the rectangular frame 213. The top and bottom of the rubber sleeve 214 protrude from the top and bottom of the rectangular frame 213, respectively, so that the rubber sleeve 214 can protect the edges of the rectangular frame 213 to prevent the connecting line 208 from being pressed out of the creases by the edges of the rectangular frame 213.

[0040] During use, when all-around lightning protection is needed, the lifting disc 2092 is lifted by the electric telescopic rod 2091, so that each connecting plate 2094 pushes the corresponding deflection plate 203 upwards, and then the end of the rectangular plate 204 connected to each deflection plate 203 is deflected away from the main lightning rod 207; at this time, the plurality of side lightning rods 205 are evenly spread around the main lightning rod 207 as the center line, and the plurality of side lightning rods 205 are in an inclined state, and the plurality of connecting lines 208 cannot be entangled together through the rectangular frame 213 and the rubber sleeve 214; when the deflection is completed, the all-around lightning protection can be realized through the plurality of side lightning rods 205 and the main lightning rod 207, so that lightning can be hit by at least one of the side lightning rods 205 or the main lightning rod 207; the connecting lines 208 of the side lightning rods 205 and the main lightning rod 207 are connected to the ground wire to guide the lightning into the ground, thereby achieving the lightning protection effect.

[0041] When lightning protection is not needed, the lifting disc 2092 is lowered by the electric telescopic rod 2091, at this time, the connecting plate 2094 pulls the deflection plate 203 downwards, so that the end of the rectangular plate 204 connected to the deflection plate 203 is deflected towards the main lightning rod 207; when the plurality of side lightning rods 205 are in a vertical state and are deflected into the semicircular notches of the limiting blocks 212, the lifting disc 2092 stops moving, at this time, the plurality of side lightning rods 205 are closely close to the periphery of the main lightning rod 207, and form a stable whole, thereby effectively ensuring the stability and safety of the overall structure in a strong wind environment.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalent, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
