Problems solved by technology

However, the current manhole cover is usually directly removed from the operation well. The manhole cover is not only easy to be lost if it is placed randomly, but also there is a possibility of accidentally falling into the well when the operation well head is fully open. In addition, the light in the operation well is poor, which is not conducive to the operator. overhaul

Embodiment

[0029] like Figure 1 to Figure 4As shown, the SF buried oil tank provided in this embodiment includes a tank body 1 and a manhole 2 and a well seat 3 arranged on the tank body 1. In this embodiment, in order to be able to monitor in real time whether the inner tank body leaks, The tank body 1 includes an inner resin-rich layer, an inner anti-seepage layer, a through-gap layer 11, an outer anti-seepage layer, and an outer resin-rich layer from the inside to the outside, wherein the inner and outer resin-rich layers are made of noon glass fiber surface felt, The resin content should not be less than 90%. The inner and outer anti-seepage layers are made of alkali-free glass fiber chopped strand mat or spray yarn, and the resin content is 65-75%. The through-gap layer 11 is filled with 3D fiberglass fabric material, mainly a composite of 3D glass fiber fabric and resin, and an anti-leakage detector is provided through the interstice layer 11, and the anti-leakage detector include...

Abstract

The invention discloses an SF buried oil tank, which includes a tank body, a manhole and a well seat arranged on the tank body, and an anti-seepage operation well is installed on the well seat, and the anti-seepage operation well includes from top to bottom The lower cylinder cover, the anti-consolidation upper cylinder, the leakage-proof middle cylinder and the leakage-proof lower cylinder are detachably connected in turn, and the leakage-proof lower cylinder is connected with the well seat. The cylinder cover includes a fixed cover plate and a movable cover plate, The fixed cover is buckled on the anti-consolidation upper cylinder, and a stepped through hole is processed in the middle of the fixed cover. One side of the movable cover is hinged to the side wall of the fixed cover on the side of the through hole and is used for movable sealing. The through hole is described, the lower surface of the movable cover is provided with two groups of clamping components, and the two groups of clamping components are respectively located on the two sides adjacent to the hinged side of the lower surface of the movable cover. The invention adopts the form of a half-open manhole cover, which reduces the risk of manhole cover loss and accidental falling into the well, and is equipped with a clamping component that can clamp a light source to irradiate the inside of the operation well, which is convenient for operators to perform maintenance.

Description

technical field [0001] The invention relates to the technical field of oil storage, in particular to an SF buried oil tank. Background technique [0002] The SF double-layer oil tank is composed of an inner tank and an outer tank, the inner tank shell is made of steel, the outer tank shell is made of glass fiber reinforced plastic, the outer tank completely contains the inner tank, and the outer tank is molded Manholes are formed, and there is a protective well seat at the manhole. The well seat is generally round or square. The purpose of the well seat is to surround the manhole on the one hand for protection, and on the other hand to connect the operation well and the ground to form a connection The operator generally enters the operation well by opening the manhole cover on the operation well, and repairs or maintains the connecting pipes at the manhole. However, the current manhole cover is usually directly removed from the operation well. The manhole cover is not only ...
