The tower body mainly plays a role of supporting the overhead line so as to keep a certain distance between the overhead line and the ground. The tower body can be a rod-shaped or tower-shaped structure and can be made of steel or reinforced concrete. The first conductive sheet 10 is disposed on the tower body, and the number of the first conductive sheets 10 may be at least one. In this embodiment, the number of the first conductive sheets 10 is four, four first conductive sheets 10 are all located at the tower foot of the tower body, and the four first conductive sheets 10 are distributed at intervals around the tower body. Correspondingly, in the present embodiment, the number of the second conductive sheet 20 and the connecting device 30 for connecting the tower body and the ground down conductor is four.
the first conducting strip 10 may be part of an angle iron for facilitating the mounting on the tower body. For example, the angle steel in an embodiment may include a mounting plate and the first conductive plate 10, which are bent from each other, the mounting plate is disposed on the tower body, so that the first conductive plate 10 is indirectly disposed on the tower body, and the tower body may be electrically connected to the first conductive plate 10 through the mounting plate. Of course, in other embodiments, the first conductive sheet 10 may also be a separate sheet-like structure, and one side of the first conductive sheet is disposed on the tower body by welding or the like. Similarly, the shape of the second conductive sheet 20 can also be designed flexibly, and in this embodiment, the second conductive sheet 20 is a separate sheet structure.
The connecting means 30 for connecting the tower body to the ground down conductor is used to contact the first conducting strip 10 with the second conducting strip 20, so that the first conducting strip 10 is electrically connected with the second conducting strip 20. The grounding body is used for being connected with the earth ground and can be buried in the earth so as to be connected with the earth ground. One end of the ground down lead is disposed on the second conductive sheet 20, and the other end is disposed on the ground body. When in normal operation, the tower body passes through the first conducting strip 10,
The second conducting strip 20, the grounding downlead and the grounding body are electrically connected with the ground, if the tower body is hit by thunder, the thunder and lightning current on the tower body can be conducted to the ground through the first conducting strip 10, the second conducting strip 20, the grounding downlead and the grounding body, and therefore the influence of the thunder and lightning current on the tower body can be avoided.
Referring to fig. 2, an embodiment of a connection device 30 for connecting a tower body and a ground down conductor includes a locking assembly 100, an insulating sleeve 200, a first insulating spacer 300, and a second insulating spacer 400, wherein the locking assembly 100 includes a rod 110, a first locking member 120, and a second locking member 130. The first locking member 120 is detachably disposed on the penetrating rod 110 and can move along the length direction of the penetrating rod 110, and the second locking member 130 is disposed on the penetrating rod 110. The insulation sleeve 200 is sleeved on the penetrating rod 110. The first insulating spacer 300 is sleeved on the through rod 110, and the first insulating spacer 300 is located between the first locking member 120 and the second locking member 130. The second insulating spacer 400 is sleeved on the through rod 110, and the second insulating spacer 400 is located between the first locking member 120 and the second locking member 130.
further, the first conductive sheet 10 is provided with a first through hole, and the second conductive sheet 20 is provided with a second through hole. In the tower, the penetrating rod 110 penetrates through the first penetrating hole and the second penetrating hole, the first insulating gasket 300 is located on one side of the first conducting strip 10, which faces away from the second conducting strip 20, and the second insulating gasket 400 is located on one side of the second conducting strip 20, which faces away from the first conducting strip 10;
When the ground down lead is electrically connected with the tower body, the first conducting strip 10 provided with the first through hole is arranged on the tower body in advance and is electrically connected with the tower body, and the second conducting strip 20 provided with the second through hole is electrically connected with the ground down lead. The first locking member 120 is separated from the penetrating rod 110 provided with the second locking member 130, the insulating sleeve 200 is sleeved on the penetrating rod 110, and the second insulating spacer 400 is sleeved on the penetrating rod 110. The penetrating rod 110 is inserted into the first through hole and the second through hole, and in this process, the insulating sleeve 200 is inserted into the first through hole and the second through hole along with the penetrating rod 110. The first insulating spacer 300 is sleeved on the penetrating rod 110, so that the first conductive plate 10 and the second conductive plate 20 are both located between the first insulating spacer 300 and the second insulating spacer 400. The first locking member 120 is disposed on the penetrating rod 110, and the first locking member 120 moves along the length direction of the penetrating rod 110, so as to lock the first insulating gasket 300, the first conducting strip 10, the second conducting strip 20, and the second insulating gasket 400 between the first locking member 120 and the second locking member, thereby enabling the first conducting strip 10 to contact with the second conducting strip 20 and realizing electrical connection, and thus the ground down lead and the tower body can be electrically connected through the first conducting strip 10 and the second conducting strip 20.
It is understood that when the down conductor is electrically connected to the tower body, the first insulating spacer 300 is located between the first locking member 120 and the first conducting plate 10, the second conducting plate 20 is located on a side of the first conducting plate 10 opposite to the first locking member 120, and the second insulating spacer 400 is located between the second locking member 130 and the second conducting plate 20.
When the electric connection between the grounding down conductor and the tower body is broken, the first locking member 120 is moved reversely along the length direction of the penetrating rod 110, so that a space is formed between the first conducting strip 10 and the second conducting strip 20. Since the insulating sleeve 200 is inserted into the first through hole and the second through hole, and the insulating sleeve 200 is sleeved on the penetrating rod 110, the insulating sleeve 200 can prevent the first conductive sheet 10 and the second conductive sheet 20 from being electrically connected through the penetrating rod 110. Since the first insulating spacer 300 is located between the first locking member 120 and the first conducting plate 10, and the second insulating spacer 400 is located between the second locking member 130 and the second conducting plate 20, the first insulating spacer 300 and the second insulating spacer 400 can prevent the first conducting plate 10 and the second conducting plate 20 from being electrically connected through the through rod 110, the first locking member 120 and the second locking member 130. Therefore, when a distance exists between the first conducting strip 10 and the second conducting strip 20, the electrical connection between the grounding down-lead and the tower body can be disconnected.
In summary, when the electrical connection between the grounding down conductor and the tower body is disconnected, the first locking member 120 is moved in the opposite direction along the length direction of the penetrating rod 110, so that the distance between the first conducting strip 10 and the second conducting strip 20 is formed. The above-described connection device 30 for connecting a tower body and a ground lead can shorten the time taken to electrically disconnect the ground lead from the tower body, without the need to unscrew the nut to completely separate the nut from the penetration rod 110 as in the conventional art, or to detach the penetration rod 110.
In this embodiment, the first fastening member 120 is a nut, and the first fastening member 120 is threadedly engaged with the threading rod 110. The first locking member 120 can be unscrewed from the penetrating rod 110, so as to facilitate the penetrating rod 110 to be inserted into the first through hole and the second through hole, and facilitate the insulating sleeve 200, the first insulating gasket 300, and the second insulating gasket 400 to be sleeved on the penetrating rod 110. The second locking member 130 is a quick-release handle, and the second locking member 130 is rotatably disposed on the rod 110. The existence of the quick-release handle can enable a distance to appear between the first conducting strip 10 and the second conducting strip 20 by rotating the quick-release handle on the premise that the first locking member 120 does not act, so that the quick disconnection of the electric connection of the grounding downlead and the tower body is realized.
in another embodiment, first retaining member 120 is a nut, first retaining member 120 is threadably engaged with threaded rod 110, and second retaining member 130 is a nut. At this time, the penetrating rod 110 and the second locker 130 may be combined to form a bolt. Alternatively, both the first locking member 120 and the second locking member 130 are nuts, and both the first locking member 120 and the second locking member 130 are in threaded engagement with the threading rod 110. In this case, the penetrating rod 110 may be a double-headed screw. Of course, in other embodiments, both first locking member 120 and second locking member 130 can be modified. For example, the first locking member 120 may be a pin, and the penetrating rod 110 has at least two insertion holes, and the at least two insertion holes are distributed along the length direction of the penetrating rod 110. By inserting the first locking member 120 into different insertion holes, on the one hand, the separable engagement of the first locking member 120 with the threading rod 110 can be achieved, and on the other hand, the first locking member 120 can be moved along the length direction of the threading rod 110.
When the second locking member 130 is a quick release handle, the quick release handle includes a quick release wheel 131, and the quick release wheel 131 is a cam or an eccentric wheel. The rotating quick release wheel 131 can press the second insulating spacer 400, the second conductive plate 20, the first conductive plate 10 and the first insulating spacer 300 onto the first locking member 120, and the first conductive plate 10 and the second conductive plate 20 can be spaced by the continuous rotation or the reverse rotation of the quick release wheel 131.
The quick release handle further comprises a handle 132, and the handle 132 is disposed on the quick release wheel 131, so that the quick release wheel 131 can be rotated by the handle 132. In the present embodiment, when the length direction of the handle 132 is the same as the length direction of the penetrating rod 110, a gap occurs between the first conductive plate 10 and the second conductive plate 20. After measurement, when the grounding down-lead is required to be electrically connected with the tower body again, the quick release wheel 131 is rotated to make the length direction of the handle 132 intersect with the length direction of the penetrating rod 110. In this embodiment, when the grounding down-lead is required to be electrically connected to the tower body again, the handle 132 needs to be rotated by at least 90 degrees to ensure the close contact between the first conductive plate 10 and the second conductive plate 20. Of course, in other embodiments, the rotation angle of the handle 132 can be designed flexibly, such as 60 degrees or 120 degrees.
referring to fig. 3, in the present embodiment, the connecting device 30 for connecting the tower body and the ground lead further includes a fixing pad 500, an arc surface 510 is formed on the fixing pad 500, and the arc surface 510 is used for cooperating with the quick release wheel 131 to fix the quick release wheel 131. Of course, in other embodiments, the fixing pad 500 can be omitted, the second insulating spacer 400 is located between the first insulating spacer 300 and the second locking member 130, and the second insulating spacer 400 has an arc surface 510 formed thereon, and the arc surface 510 is used for cooperating with the quick release wheel 131 to fix the quick release wheel 131.
referring to fig. 4, further, a locking groove 520 is formed on the arc surface 510, a locking block 133 is disposed on a peripheral wall of the quick release wheel 131, and the locking block 133 can extend into the locking groove 520 to prevent the quick release wheel 131 from rotating to some extent. When the grounding downlead is electrically connected with the tower body, the handle 132 is pulled to enable the quick release wheel 131 to rotate until the locking block 133 extends into the locking groove 520, and the handle 132 is stopped to be continuously pulled. When the grounding downlead is disconnected from the electric connection with the tower body, the quick release wheel 131 is rotated reversely. In this embodiment, the locking groove 520 is a bar-shaped groove, and the locking block 133 is bar-shaped. Of course, in other embodiments, the shapes of the locking groove 520 and the locking block 133 can be designed flexibly. Alternatively, the locking groove 520 and the locking block 133 may be omitted.
Referring to fig. 2 and 5, in the present embodiment, the through rod 110 includes a rod portion 111, the rod portion 111 includes a polished rod section and a threaded section, and the first locking member 120 is threadedly engaged with the threaded section. Specifically, the threaded section is provided with an external thread, and the first locking member 120 is screwed on the threaded section. The insulation sleeve 200 is sleeved on the polished rod section so as to increase the fit tightness between the insulation sleeve 200 and the penetrating rod 110, and to a certain extent, the insulation sleeve 200 can be prevented from wrinkling.
Furthermore, the penetrating rod 110 further includes a limiting portion 112, the limiting portion 112 is disposed at one end of the rod portion 111, the limiting portion 112 protrudes out of the rod portion 111 along a radial direction of the rod portion 111, and an end surface of the insulating sleeve 200 abuts against the limiting portion 112. When the insulating sleeve 200 is sleeved, the insulating sleeve 200 is sleeved on the threaded section, then the insulating sleeve 200 moves relative to the through rod 110 along the length direction of the through rod 110, and when the end surface of the insulating sleeve 200 abuts against the limiting part 112, the insulating sleeve 200 stops moving. The existence of the limiting part 112 can limit the position of the insulating sleeve 200, so that the insulating sleeve 200 can be conveniently moved to a desired position.
Referring to fig. 1, further, the insulation sleeve 200 is located between the threaded section and the limiting portion 112, so that the insulation sleeve 200 is not sleeved on the threaded section, thereby improving the close fit between the insulation sleeve 200 and the penetrating rod 110 to a certain degree. Of course, in other embodiments, an end of the insulating sleeve 200 away from the limiting portion 112 may be sleeved on the partial threaded section. It should be noted that in the present embodiment, the penetrating rod 110 is conductive, so when a distance occurs between the first conductive sheet 10 and the second conductive sheet 20, both the first conductive sheet 10 and the second conductive sheet 20 need to be sleeved on the insulating sleeve 200, and neither the first conductive sheet 10 nor the second conductive sheet 20 directly contacts the penetrating rod 110.

Of course, in other embodiments, the first elastic member 710 and the second elastic member 720 can be omitted.
the concrete working principle of the tower and the connecting device 30 for connecting the tower body and the grounding down lead in the embodiment is as follows:
When the ground down lead is electrically connected with the tower body, the tower body is erected on the ground in advance, and the first conducting strip 10 provided with the first through hole is arranged on the tower body in advance and is electrically connected with the tower body. The grounding body is embedded in the ground in advance to be connected with the ground, one end of the grounding downlead is arranged on the second conducting strip 20 provided with the second through hole, the other end of the grounding downlead is arranged on the grounding body, and the second conducting strip 20 is connected with the ground through the grounding downlead and the grounding body.
The first locking member 120 is separated from the penetrating rod 110 with the second locking member 130, the quick release handle is rotatably disposed on the penetrating rod 110, the insulating sleeve 200 is sleeved on the penetrating rod 110, the fixing pad 500, the second elastic member 720 and the second insulating pad 400 are sleeved on the penetrating rod 110, wherein the second elastic member 720 is located between the second insulating pad 400 and the fixing pad 500, and the fixing pad 500 is located between the second elastic member 720 and the quick release handle.
the penetrating rod 110 is inserted into the first through hole and the second through hole, and in this process, the insulating sleeve 200 is inserted into the first through hole and the second through hole along with the penetrating rod 110. The second conductive plate 20 is located between the first conductive plate 10 and the second insulating spacer 400, and both the first conductive plate 10 and the second conductive plate 20 are in contact with the penetrating rod 110 through the insulating sleeve 200.
The first insulating pad 300 and the first elastic member 710 are sleeved on the penetrating rod 110, wherein the first insulating pad 300 is located between the first conductive sheet 10 and the first elastic member 710. The first locking member 120 is disposed on the penetrating rod 110, and the first locking member 120 moves along the length direction of the penetrating rod 110 to lock the first insulating pad 300, the first elastic member 710, the first conductive plate 10, the second conductive plate 20, the second insulating pad 400, and the second elastic member 720 to a certain extent. The quick release wrench is rotated to test the tightness degree, if the resistance is not sensed when the length direction of the handle 132 is the same as the length direction of the threading rod 110, the first locking member 120 is continuously moved until the resistance is sensed when the length direction of the handle 132 is the same as the length direction of the threading rod 110. The handle 132 is pulled to rotate the handle 132 by at least 90 degrees, so as to ensure the close contact between the first conductive plate 10 and the second conductive plate 20, and the first conductive plate 10 is in close contact with the second conductive plate 20 to realize electrical connection, so that the grounding down lead can be electrically connected with the tower body through the first conductive plate 10 and the second conductive plate 20.
When the electric connection between the grounding downlead and the tower body is broken, the quick-release handle is reversely rotated, so that a space is formed between the first conducting strip 10 and the second conducting strip 20. Since the insulating sleeve 200 is inserted into the first through hole and the second through hole, and the insulating sleeve 200 is sleeved on the penetrating rod 110, the insulating sleeve 200 can prevent the first conductive sheet 10 and the second conductive sheet 20 from being electrically connected through the penetrating rod 110. Since the first insulating spacer 300 is located between the first locking member 120 and the first conducting plate 10, and the second insulating spacer 400 is located between the second locking member 130 and the second conducting plate 20, the first insulating spacer 300 and the second insulating spacer 400 can prevent the first conducting plate 10 and the second conducting plate 20 from being electrically connected through the through rod 110, the first locking member 120 and the second locking member 130. Therefore, when a distance exists between the first conducting strip 10 and the second conducting strip 20, the electrical connection between the grounding down-lead and the tower body can be disconnected.
in summary, when the electrical connection between the grounding down conductor and the tower body is disconnected, the quick-release handle is rotated reversely, so that a gap is formed between the first conducting strip 10 and the second conducting strip 20. Of course, in other embodiments, the first conductive plate 10 and the second conductive plate 20 may be spaced apart by moving the first locking member 120 in the reverse direction. The above-described connection device 30 for connecting a tower body and a ground lead can shorten the time taken to electrically disconnect the ground lead from the tower body, without the need to unscrew the nut to completely separate the nut from the penetration rod 110 as in the conventional art, or to detach the penetration rod 110.
