Multifunctional device for preventing power transmission line tower from being damaged by external force
The invention discloses an external damage prevention multifunctional device for a power transmission line tower, which is arranged around a tower foot of the power transmission line tower in a flood prevention area and comprises a concrete column, a spiral anchor rod and a horizontal grounding wire, the bottom of the concrete column and the top of the spiral anchor rod are connected through flange bolts. The concrete column is positioned above the spiral anchor rod; the spiral anchor rod is fixed under the ground; one part of the concrete columns are located under the ground, and the other part of the concrete columns are located above the ground and are perpendicular to the ground; the horizontal grounding wire is positioned below the ground and is flush with the position of the flange; one end of the horizontal grounding wire is connected with a grounding hole reserved in the flange, and the other end of the horizontal grounding wire is connected with a ground wire on the tower leg of the tower. The grounding device is simple in structure, convenient to carry, simple and convenient to install and high in universality, effectively reduces the impact damage of large floaters to a tower in a flood prevention area, and reduces the resistance of the grounding device.
本发明公开了输电线路杆塔防外力破坏多功能装置，设置在防洪区域的输电线路杆塔塔脚周围，防外力破坏多功能装置包括混凝土柱、螺旋锚杆和水平接地线；混凝土柱的底部和螺旋锚杆的顶部均通过法兰螺栓连接；混凝土柱位于螺旋锚杆的上方；螺旋锚杆固定于地面下方；一部分混凝土柱位于地面下方，另一部分混凝土柱位于地面上方，与地面垂直；水平接地线位于地面下方，与法兰的位置平齐；水平接地线一端与法兰预留的接地孔连接，另一端与位置对应的杆塔塔腿上的地线连接。结构简单，携带方便，安装简便，通用性强，有效的降低位于防洪区域内杆塔受到大块漂浮物撞击破坏以及降低接地装置的电阻。
