Abstract
The invention discloses a pressure-tolerant well cover. A well ring and a gland are fastened and connected by virtue of bolts, a gap is arranged between the well ring and the gland, the well cover is embedded in the gap, and the well cover is in a shape of a dome. Compared with the prior art, the invention has the advantages that a pressure can be dispersed downward and outward when the dome-shaped well cover is pressed and the well cover can bear a higher force and is more pressure-tolerant.
Description
Technical field
The invention belongs to the communal facility field, be specifically related to the well lid of various wells in a kind of network of underground.
Background technology
Transmission line of electricity enters the city or enters densely populated zone, just changes cable into by overhead wire, and laying and the maintenance in later stage and inspection for the ease of cable must arrange cable shaft in certain length or specific position.Current, the well lid of cable shaft is often damaged by pressure by vehicle, has increased maintenance workload, simultaneously, has also caused the generation of some accidents.The present invention uses the inboard stressed principle much smaller than the outside of eggshell, well lid is made convex, to satisfy the needs of urban construction and power network development.
Summary of the invention
Given this, the well lid that provides a kind of durable, withstand voltage network of underground well head to use is provided the object of the invention.
For solving above technical problem, technical scheme provided by the invention is, a kind of withstand voltage well lid is provided, and walling crib is connected by screw fastening with gland, is provided with a slit between walling crib and the gland, and well lid is embedded in this slit, and described well lid is dome-shaped.
Preferably, described walling crib is torus.
Preferably, described well lid hollow, the close edge of upper surface is provided with feeding port.
Preferably, the main body of described gland is torus, and its lower surface is divided into plane area and sphere district, fits in plane area and walling crib upper surface, fits in the upper surface of sphere district and well lid.
Compared with prior art, during the Arched well cover pressurized, outwards dispersive pressure downwards, so the strength that well lid can bear is larger, more withstand voltage.

The specific embodiment
Describe below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1 to Fig. 6.The withstand voltage well lid that the present embodiment is described is made of walling crib 1, well lid 2 and gland 3 three parts.Walling crib 1 is torus, is provided with screw on it, correspondingly with it is, also is provided with screw on the gland 3, and walling crib 1 and gland 3 are connected by screw fastening.The main body of gland 3 is torus, and its lower surface is divided into plane area and sphere district, fits in plane area and walling crib 1 upper surface.Between walling crib 1 and the gland 3 slit is arranged, well lid 2 is embedded in this slit, fits in the sphere district of gland 3 and the upper surface of well lid 2.Described well lid 2 is dome-shaped, hollow, and the close edge of upper surface is provided with feeding port 21.Walling crib 1 equates with external diameter and the internal diameter of gland 3.The bottom surface of well lid 2 is annular, the sphere district equal diameters of the external diameter of this annular and gland 3, and internal diameter equates with the internal diameter of walling crib 1.
During installation, first with prefabricated profiled walling crib by design attitude into fixing, after walling crib is fixing, well lid is put on the walling crib, the well lid trim ring is placed on the well lid by the mode of being convenient to screw fastening, and carries out fastening with screw.
Only be preferred embodiment of the present invention below, should be pointed out that above-mentioned preferred embodiment should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with the claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
