Problems solved by technology

Because there is a gap between the well cover and the well seat, and it does not have the waterproof function, water often occurs in the power well, and even water at the bottom of the power well often occurs, which affects the safe operation of the cable and creates a safety hazard
[0003] On the other hand, because the gap between 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 gap between the well cover and the well seat is easy to enter the foreign matter. When the power well needs to be overhauled, it is often difficult to open the well cover
In addition, with the increasing demand for power cables, the theft of power manhole covers also continues to occur. The theft of power manhole covers will not only cause the loss of the power manhole cover itself, but will also cause the cables in the power well to be exposed and easily damaged. be destroyed, and will bring safety hazards to pedestrians and vehicles

specific Embodiment 1

[0053] Specific embodiment one: as figure 1 , figure 2 As shown, a water drainage power well structure includes a well body 1 and an electric well cover assembly for sealing the wellhead of the well body. The electric well cover assembly includes a well base 2.1 and a well cover 2.2. The well base 2.1 is fixed in the wellhead of the well body. The well base 2.1 includes an annular seat ring 2.1.1 and a vertical guide sleeve 2.1.2 arranged on the upper surface of the annular seat ring. In this embodiment, the annular seat ring and the vertical guide sleeve One piece. The edge of the well cover 2.2 is provided with an annular boss 2.2.1 extending downward. In this embodiment, the well cover and the annular boss are formed together. The well cover is supported on the annular seat ring through the annular boss, and the well cover is located in the vertical guide sleeve. The edge of the well cover 2.2 is provided with an outwardly extending annular flange 2.2.2, and the inner...

specific Embodiment 2

[0062] Specific embodiment two: the specific structure of this embodiment is with reference to specific embodiment one, and its difference is:

[0063] Such as image 3 , Figure 4 As shown, a water drainage power well structure also includes a linkage anti-theft and cover opening device 3 . The linked anti-theft and cover opening device 3 includes a walking support 3.5 arranged on the annular seat, a horizontal guide bush 3.2 arranged on the lower surface of the well cover, a sliding guide rod 3.3 slidably arranged in the horizontal guide bush, and a sliding guide rod 3.3 arranged on the well cover. The driving executive mechanism 3.7 used to drive the sliding guide rod to slide along the horizontal guide sleeve, the latch 3.4 connected with the sliding guide rod, the vertical support rod 3.12 arranged on the sliding guide rod, the rotation device arranged at the lower end of the vertical support rod The roller 3.6, the annular draw-in groove 3.1 arranged on the inner side...

Abstract

The invention discloses a power well structure for accumulating water drainage, and aims to provide a method that can effectively improve the water inflow of the power well in the prior art, and even cause water accumulation at the bottom of the power well, which affects the safe operation of cables in the power well Power well structure for water drainage. It includes a well body and an electric well cover assembly for sealing the wellhead of the well body. The electric well cover assembly includes a well seat and a well cover. The well seat is fixed in the well head of the well body. The vertical guide sleeve on the surface, the well cover is located in the vertical guide sleeve, the edge of the well cover is provided with an annular flange extending outward, and the inner surface of the vertical guide sleeve is provided with an annular groove for accommodating the annular flange. There is an annular water accumulation groove on the bottom surface of the well body, an annular diversion groove is provided on the side of the well body facing the vertical guide sleeve, and a number of diversion channels connecting the annular water accumulation groove and the annular diversion groove are arranged in the vertical guide sleeve, and the side wall of the well body There are several drainage channels inside.

Description

technical field [0001] The invention relates to the field of electric wells, in particular to a structure for accumulating water drainage electric wells. Background technique [0002] The electric well cover is installed on the wellhead of the well body of the electric well, and is used for sealing the wellhead of the electric well. Present electric well cover generally comprises well seat and well cover, and well seat is fixed on the wellhead of electric well, and well cover seals the wellhead of electric well. Because there is a gap between the well cover and the well base, and it does not have waterproof function, water often occurs in the power well, and even water accumulation at the bottom of the power well often occurs, which affects the safe operation of the cable and creates a safety hazard. [0003] On the other hand, because the gap between the well cover and the well seat is very small, the crowbar cannot be inserted between the well cover and the well seat, and...
