Electric manhole cover for easy opening and maintenance

Abstract

The invention discloses a power well lid convenient to open for overhauling. According to the power well lid convenient to open for overhauling, the thievery-prevention function is achieved, and the well lid is conveniently opened so as to overhaul a power cable well. The power well lid comprises a well seat, a well lid body and a linkage-type thievery-prevention and lid opening device; the well seat comprises an annular seat ring and a vertical guiding sleeve arranged on the upper surface of the annular seat ring; an annular boss formed in the mode of extending downwards is arranged at the edge of the well lid body; and the linkage-type thievery-prevention and lid opening device comprises a travelling supporting piece, a horizontal guiding sleeve, a sliding guiding rod, a driving executing mechanism, a plug pin, a vertical supporting rod, an idler wheel, an annular clamping groove and a plug pin via hole, wherein the travelling supporting piece is arranged on the annular seat ring, the horizontal guiding sleeve is arranged on the lower surface of the well lid body, the sliding guiding rod is slidably arranged in the horizontal guiding sleeve, the driving executing mechanism is used for driving the sliding guiding rod to slide along the horizontal guiding sleeve, the plug pin is connected with the sliding guiding rod, the vertical supporting rod is arranged on the sliding guiding rod, the idler wheel is rotationally arranged at the lower end of the vertical supporting rod, the annular clamping groove is formed in the inner side face of the vertical guiding sleeve, and the plug pin via hole is formed in the annular boss.

Description

technical field [0001] The invention relates to the field of electric cable wells, in particular to an electric well cover that is easy to open and maintain. Background technique [0002] The electric well cover is installed on the wellhead of the electric cable well, and is used for sealing the wellhead of the electric cable well. The current electric well cover generally includes a well base and a well cover. The well base is fixed on the wellhead of the electric cable well. The well base includes an annular seat ring and a vertical guide sleeve arranged on the upper surface of the annular seat ring. On the annular seat, thereby sealing the wellhead of the power cable well. In the current electric well cover, because the gap between the vertical guide sleeve of the well cover and the well seat is very small, the crowbar cannot be inserted between the well cover and the well seat, and during the long-term use of the electric well cover, the vertical gap between the well co...

Problems solved by technology

In the current electric well cover, since the gap between the vertical guide sleeve of the well cover and the well seat is very small, the crowbar cannot be inserted between the well cover and the well seat, and during the long-term use of the electric well cover, the vertical gap between the well cover and the well seat The gap between the guide sleeves is also easy to enter foreign matter. When the power cable well needs to be overhauled, there is often the problem of difficulty in opening the well cover.

[0003] On the other hand, with the increasing demand for power cables, the theft of cable manhole covers also continues to occur. The theft of cable manhole covers will not only cause the loss of the cable manhole cover itself, but also cause the loss of cables in the power cable well. Exposed, easy to be damaged, and will bring safety hazards to pedestrians and vehicles
