[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a pole tower. By arranging steel bars 102 and lightning protection components 200, it can prevent cracks from appearing on the outer concrete wall of the support column 101 due to damage caused by the impact of lightning, and prevent the support column 101 from bending, tilting or even breaking, which will cause the tension of the wire to tighten and affect the safe operation of the wire.

[0029] Specifically, the lightning receiving component 100 includes a support column 101 and a plurality of steel bars 102 inserted into the support column 101; and the lightning protection component 200 includes a connecting ring 201 arranged on the steel bars 102, a lightning blocking component 202 arranged at the bottom of the connecting ring 201, and a lightning inducing component 203 arranged in the support column 101; the lightning protection component 200 is arranged in the accommodating cavity N of the support column 101.

[0030] Among them, the steel bars 102 are evenly arranged in a circle around the axis of the support column 101, which is beneficial for the 360-degree outer wall of the concrete support column 101 to conduct lightning to the corresponding steel bars 102 when struck by lightning, and the steel bars 102 then conduct lightning to the lightning protection assembly 200, thereby avoiding the outer wall of the concrete support column 101 from being broken due to the inability to conduct lightning to the nearest steel bars 102 and lightning protection assembly 200 after being struck by lightning. After the connecting rings 201 are connected to the steel bars 102, it is beneficial for several steel bars 102 to use the same lightning arrester 202 and lightning induction component 203 to avoid waste.

[0031] In summary, by providing the steel bars 102 and the lightning protection component 200, when a certain location on the outer wall of the support column 101 is struck by lightning, the lightning is conducted to the connecting ring 201 through the guidance of the steel bars 102, and then conducted to the lightning blocking component 202 through the connecting ring 201. Since the resistance of the lightning blocking component 202 is high, the current is reduced, thereby reducing the impact on the support column 101. The high resistance of the lightning blocking component 202 converts electrical energy into heat energy, causing the lightning blocking component 202 to bend and abut against the lightning attracting component 203 and be electrically connected to the lightning attracting component 203, so that the lightning attracting component 203 guides the current to the ground. When the lightning blocking component 202 bends, the ventilation holes are exposed, allowing the wind to pass through the ventilation holes and cool the lightning blocking component 202 when passing through it, preventing cracks from appearing due to damage caused by the impact of lightning on a certain location on the outer concrete wall of the support column 101, and preventing the support column 101 from bending, tilting or even breaking, resulting in the tightening of the wire tension and affecting the safe operation of the wire.

[0032] Embodiment 2

[0033] Referring to Figures 1 to 4 , this is the second embodiment of the present utility model. Different from the previous embodiment, by providing the lightning blocking component 202 and the lightning attracting component 203, cracks are avoided from appearing due to damage caused by the impact of lightning on a certain location on the outer concrete wall of the support column 101, and the tightening of the wire tension caused by the bending, tilting or even breaking of the support column 101 is prevented, thereby affecting the safe operation of the wire.

[0034] Specifically, several steel bars 102 are evenly arranged around the axis of the support column 101 in a circumferential direction.

[0035] A first placement groove for accommodating the connecting ring 201 is formed in the support column 101, and the connecting ring 201 is fixedly sleeved with several steel bars 102.

[0036] A second placement groove for accommodating the lightning blocking component 202 is formed in the support column 101.

[0037] The lightning blocking component 202 includes a connecting block 202e provided at the bottom of the connecting ring 201.

[0038] A connecting rod 202d is provided on the connecting block 202e, and an inductance element 202c is provided at one end of the connecting rod 202d away from the connecting block 202e.

[0039] A fixing piece is provided at the bottom of the inductance element 202c, and a metal expansion strip 202a is provided on the fixing piece.

[0040] A ventilation hole penetrating through the support column 101 and communicating with the second placement groove is formed in the support column 101, and dust-proof L-shaped plates 202b adapted to the ventilation hole are provided at both ends of the metal expansion strip 202a.

[0041] Among them, the distance from the side wall of the accommodating space N to the outer wall of the support column 101 is about 5 cm to prevent the support column 101 from bending and breaking. A first mounting groove for accommodating the connecting ring 201 is opened in the support column 101, and an inspection door connected to the first mounting groove and the second mounting groove is provided on the support column 101.

[0042] Normally, the end surface of the dust-blocking L-shaped plate 202b blocks the ventilation holes to prevent dust from entering through the ventilation holes and adhering to the inductor element 202c, causing poor contact of the inductor element 202c. The inductance of the inductor element 202c is 10mH to 100mH.

[0043] The metal expansion strip 202a is made of aluminum and has a rectangular shape, and the fixing piece is made of aluminum and has a U-shape.

[0044] The support column 101 is wide at the bottom and narrow at the top, and the steel bars 102 are inclined toward the direction close to the axis of the support column 101 .

[0045] In summary, by providing the lightning arrester 202 and the lightning inducing member 203, when a certain place on the outer wall of the support column 101 is struck by direct lightning, the steel bars near the place will guide the current through the connecting ring 201, the connecting block 202e and the connecting rod 202d into the inductor element 202c. The inductor element 202c converts part of the electrical energy into thermal energy. The bent end of the metal expansion strip 202a after being heated contacts with the top of the conductive plate 203a to guide the current through the grounding guide wire 203b into the underground, thereby preventing the outer concrete outer wall of the support column 101 from being damaged and cracked due to the impact of lightning, and preventing the support column 101 from bending, tilting or even breaking, causing the tension of the wire to tighten and affecting the safe operation of the wire.

[0046] Example 3

[0047] Reference Figures 1 to 4 , which is the third embodiment of the utility model. Different from the previous embodiment, by providing a dust-blocking L-shaped plate 202b, wind enters the support column 101 from the ventilation hole and cools down the inductor element 202c, preventing the temperature from being higher than the tolerance value of the inductor element 202c, thereby improving the service life of the support column 101.

[0048] Specifically, a through hole communicating with the second placement groove is provided in the support column 101, and a ground guide line 203b connected to the ground is provided in the through hole.

[0049] The bottom inner wall of the second placement groove is provided with a conductive plate 203a fixedly connected to the ground guide wire 203b.

[0050] Among them, the conductive plate 203a faces the bottom of the metal expansion strip 202a, facilitating the contact between the end of the metal expansion strip 202a and the top of the conductive plate 203a when the metal expansion strip 202a bends. The cross-sectional area of the ground connection lead wire 203b is a galvanized flat steel of 80 square millimeters.

[0051] In summary, by providing the dust-proof L-shaped plate 202b, since the resistance of the inductive element 202c is high, part of the electrical energy is converted into heat energy, causing the two ends of the metal expansion strip 202a to bend away from the heating side after being heated, driving the dust-proof L-shaped plate 202b to expose the ventilation hole, enabling the wind to enter the support column 101 through the ventilation hole and cool the inductive element 202c, preventing the temperature from exceeding the tolerance value of the inductive element 202c and improving the service life of the support column 101.
