Abstract

The invention relates to the technical field of drainage equipment, in particular to a bolt type underwater sealing door. The sealing door comprises a doorframe fixed on a wall, and a door panel which can be laterally opened and is hinged to the side of the front of the doorframe, wherein a sealing strip is arranged between the doorframe and the door panel; the sealing door is characterized in that a plurality of bolt structures are formed between the door panel and the doorframe; each bolt structure comprises a locking wedge block fixed on the inner side of the doorframe and a rotating shaft penetrating through the door panel; a wedge head is arranged on the inner side end, which penetrates through the door panel, of the rotating shaft; a handle is mounted on the end, which is positioned on the outer side of the door panel, of the rotating shaft; the wedge head is of a plate structure of which one end is fixed on the inner side end of the rotating shaft and can rotate along with the rotating shaft; when the other end of the wedge head rotates to the side, which deviates from the door panel, of the wedge block and is tightly attached to the wedge block, the door panel is closed onto the doorframe. The sealing door disclosed by the invention is simple in structure and convenient to mount and operate, can be widely applied to underwater communicating part of underground facilities so as to allow operators or construction equipment to pass, and has an extremely high popularization value.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a bolt type underwater airtight door. Background technique [0002] In my country's urban water supply and drainage projects, large underground storage tanks (such as storage tanks, etc.) are often composed of a group of relatively independent unit storage tanks, which are connected to each other through the overflow at the top of the partition wall. During the initial stage of construction and later maintenance of the reservoirs, equipment and personnel can only be transported in and out through the entrances and exits built on the ground at the top of the reservoirs of each unit. Several entrances and exits on the top of each unit storage tank will greatly affect the landscape on the top ground of the large underground storage tank. As cities in our country have higher and higher requirements for ground landscape, for large underground storage tanks, it is required ...
