Problems solved by technology

This single-point locking method has poor sealing performance, and after the watertight door is manufactured, it can only be subjected to a hydraulic test with a pressure not higher than 0.25MPa, and the internal and external hydraulic tests will affect the structure of the watertight door. , performance is affected, so internal and external hydraulic tests can only be carried out by sampling inspection, but cannot ensure the pressure resistance of all products, resulting in potential safety hazards in later use

Embodiment Construction

[0013] Such as Figure 1 to Figure 3 As shown, the pressure-resistant watertight round door for ships of the present invention comprises a door panel 2 and a short cylinder 1 used as a door frame. The door panel 2 is an outwardly protruding spherical panel with a through hole at its central position. There is a glass plate, and the glass plate and the through hole are sealed and fixedly connected to form a glass observation window 3 . One side of the door panel 2 and the short cylinder 1 is hinged together by a hinge 11, and there is a locking mechanism 4 between the door panel 2 and the short cylinder 1 on the opposite side of the hinge point. The locking mechanism 4 includes a second bushing 16, the second The shaft sleeve 16 is fixed on the door panel 2, and the second shaft sleeve 16 has a second rotating shaft 17, the two ends of the second rotating shaft 17 protrude outside the second shaft sleeve 16, and there is a handle on the extended end thereof 6. A deadbolt 1...

Abstract

The invention relates to a pressure-proof watertight circular door for ships and warships. The pressure-proof watertight circular door comprises a door plate and a short cylinder, wherein the door plate and one side of the short cylinder are hinged together, and a locking mechanism is arranged between the door plate at the opposite side of a hinge point and the short cylinder. The characteristic of the pressure-proof watertight circular door is that a turning ring is sleeved on one end of the short cylinder close to the door plate, and is in axial fixed matching with the short cylinder and in radial rotatable matching with the short cylinder. Outer bosses are uniformly distributed at the periphery of the door plate, inner bosses are uniformly distributed at the inner side of one end of the turning ring corresponding to the door plate, and inner bosses are located above the outer bosses. A first shaft sleeve is fixed on the outer wall of the short cylinder, and a first rotating shaft is arranged in the first shaft sleeve. A gear is fixed on the first rotating shaft, an arc-shaped rack is fixed at the outer side of the turning ring, and the arc-shaped rack and the gear are meshed together. A handle for controlling the turning ring to rotate is arranged on the first rotating shaft. Due to the adoption of the watertight circular door, the sealing property can be improved; and after the watertight circular door is manufactured, hydraulic tests can be carried out on the inner side and the outer side of the watertight circular door, but the structure and the performance are not influenced, and thus, the potential safety hazard in the use process is lowered.

Description

technical field [0001] The invention relates to a watertight door for a ship, in particular to a watertight door on the bulkhead of a ship that is applicable to high water pressure requirements. Background technique [0002] At present, the watertight doors of water pressure resistance used on military ships or civilian ships usually include a single steel door panel and a short cylinder used as a door frame. The short cylinder is used to connect with the bulkhead of the ship, and the door panel and One side of the short cylinder is hinged together, and a locking mechanism located on the opposite side of the hinge point is used to realize the sealing fit between the door panel and the short cylinder. This single-point locking method has poor sealing performance, and after the watertight door is manufactured, it can only be subjected to a hydraulic test with a pressure not higher than 0.25MPa, and the internal and external hydraulic tests will affect the structure of the wate...
