Embodiment Construction

[0035] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0036] In the present invention, unless otherwise stated, the use of directional words such as "upper, lower" generally refers to the upper, lower in the usual sense when the manhole cover is normally installed in the manhole with the opening facing upward. lower position. For example, the lower side of the pressing lock plate is the side where the pressing lock plate and the cover body are in contact with each other when the manhole cover is normally installed.

[0037] like Figure 3 to Figure 6 As shown, the installation structure of the manhole cover provided by the present invention includes a manhole 6, a cover body 1, a tightening handle 2 with an internal threa...

Abstract

The invention discloses a man-hole cover mounting structure, comprising a man-hole (6), a cover body (1), a fastening handle (2) with internal threads at the head part, and a pressing lock plate (3) hinged around the man-hole; a double-screw bolt (11) is arranged on the cover body (1); the fastening handle (2) is connected with the double-screw bolt (11) by the internal threads; a protruding part (32) is arranged the lower side, close to the hinging end, of the pressing lock plate (3); when the cover body (1) is positioned in the state of closing the man-hole (6), the fastening handle (2) presses the pressing lock plate (3) to enable the protruding part (32) to press the edge of the top face of the cover body (1). In addition, the invention also discloses a storage tank comprising the man-hole mounting structure, and the man-hole (6) is formed in the body of the storage tank. According to the man-hole cover mounting structure, the airtightness of the storage tank can be improved, the connection is firmer and more stable and problems such as material leakage are effectively avoided.

Description

technical field [0001] The invention relates to the field of material storage tanks, in particular to an installation structure of a manhole cover. In addition, the present invention also relates to a storage tank including the installation structure of the manhole cover. Background technique [0002] The manhole is a safety emergency ventilation device installed on the top of the storage tank. It is usually used in conjunction with fire extinguishers and mechanical breathing valves to avoid accidents caused by sudden overpressure or vacuum in the tank caused by accidental reasons. In addition, manholes are provided to facilitate access and ventilation for personnel during installation, cleaning and maintenance. [0003] Manhole covers are usually installed on manholes, which play an important role in preventing material loss and fire prevention. like figure 1 and figure 2 Shown is the most common installation structure of a manhole cover at present. After the circular ...
