Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown, an anti-theft power well includes a well body 1 , the well body 1 is hollow inside, and a mounting groove 12 is opened on the top thereof, and the mounting groove 12 is used for placing a well cover 2 . The cross section of the well cover 2 is circular, and its upper surface is inclined from the center to the surroundings, and the center is the highest point; the side walls of the well cover 2 are inclined. The well body 1 is also provided with a drainage groove 13, one end of the drainage groove 13 communicates with the installation groove 12, and the other end leads to the outside of the well body 1, so as to facilitate the drainage of the water flow on the well cover 2, thereby preventing the water flow from entering the well body 1 and affecting the well. Operation of electrical facilities.

[0039] Such as figure 1 , ...

Abstract

The invention relates to electrical infrastructures and discloses a theftproof electricity manhole. The theftproof electricity manhole comprises a manhole body and a manhole lid at the top of the manhole body, wherein the manhole lid is provided with a circular stepping groove, a rotating ring is rotatingly connected inside the circular stepping groove and provided with a plurality of inserting holes, inside which are slidingly connected with sliding columns of different lengths, the bottom of every sliding column is fixedly provided with a gear piece, and all the gear pieces are assembled into a gear; the manhole lid is rotatingly connected with a rotating rod for driving the gear pieces to rotate, the bottom of the manhole lid is fixedly provided with a connecting rod which is provided with a bar groove, and a rack engaged with the gear pieces is slidingly connected inside the bar groove; the inner wall of the manhole body is provided with a sliding groove allowing the rack to enterin; a plurality of bolts with elastic blocks are matched by insertion inside the inserting holes, and the insides of the inserting holes are provided with clamping grooves for clamping the elastic blocks. Due to the fact that the sliding columns are different in length, the gear pieces can be assembled only when the bolts of accurate lengths are inserted, namely the lengths serve as a password toachieve theftproof effects; meanwhile, the theftproof electricity manhole is convenient to mount and dismount and saves time and labor.

Description

technical field [0001] The invention relates to an electric power infrastructure, in particular to an anti-theft electric well. Background technique [0002] In terms of electricity, for the convenience of maintenance and threading, a vertical passage for people to enter is excavated at intervals, that is, a power well. At present, ductile iron manhole covers are widely used in urban water supply wells, sewage wells and water meter wells because of their good pressure bearing capacity and long service life. They are also often used as manhole covers for power wells. However, due to the recycling value of iron, manhole covers are often stolen, burying safety hazards for pedestrians. If manhole covers are stolen, passers-by can easily fall into the well, causing personal safety accidents. [0003] The Chinese patent document with the notification number CN201406694Y discloses a new type of anti-theft inspection well cover and its special opening sleeve, including the upper co...
