Description

Multifunctional floor for manned submersible cabin and cabin space adjustment method

technical field

The invention relates to the technical field of manned submersibles, in particular to a multifunctional floor used in a manned submersible cabin and a cabin space adjustment method.

Background technique

The manned compartment of the manned submersible is the work and rest space for the submersible to perform underwater tasks. Since the working depth of the manned submersible is generally several thousand meters, the manned cabin is subjected to huge deep water static pressure. In order to meet the structural strength requirements, the manned cabin is generally designed as a spherical shell type, and the inner diameter of the cabin is generally not greater than 2.1m, and Usually need to carry 3 submersibles to perform dive missions. At the same time, a large number of submersible display and control devices 8 and life support devices 9 need to be installed inside the narrow cabin, and the space 10 for personnel activities is extremely limited. The typical layout of the manned submersible cabin is shown in Figure 1, which is the side of the manned submersible cabin. View, Figure 2 is the front view of the manned submersible cabin.

There are two main working states for the submersible in the cabin: the first is the rest state, the submersible observes the display interface in front of the cabin and monitors the data of the submersible. In the observation state, the submersible observes the external environment of the submersible through the side observation window. At this time, the submersible generally leans forward as much as possible on the basis of the knee-tuck sitting position, or observes the external environment in a side-lying posture.

According to the analysis of ergonomics, when the submersibles on both sides are at rest, the floor area should be as large as possible to facilitate the personnel to change the sitting position, thereby improving comfort; when the submersibles on both sides are in the observation state, the upper body should be supported , which can delay muscle fatigue and facilitate long-term observation of the external environment of the submersible.

SUMMARY OF THE INVENTION

2. The adjustment process of increasing the sitting posture space suitable for the submersible's resting state: remove the positioning pin 502, pull out the support rod 401 from the limit hole 402, and push the support plate 2. At this time, the first link 301, the second link Both the connecting rod 302 and the support rod 401 are rotated until the first connecting rod 301 , the second connecting rod 302 and the support rod 401 are crossed and folded under the fixed floor 1 , and the support plate 2 returns to the recessed position of the fixed floor 1 .

The concrete structure and working principle of the present invention are as follows:

As shown in Figures 3 and 4, in order to adapt to the internal structure of the submersible, the fixed floor 1 is made into a fan shape as a whole, and its arc edge is attached to the interior of the submersible. One of the straight sides of the fan shape is provided with a gap 101. There is a support plate 2 that fits right into it. In order to improve the comfort of the submersible, the support plate 2 in this embodiment is set in the shape of a right-angled trapezoid, and the acute angle at the bottom edge is chamfered. A connecting plate 7 is arranged at the right angle of the bottom edge of the supporting plate 2. The connecting plate 7 is a right-angled angle steel, one of which is fixed on the side of the supporting plate 2 facing the bottom surface, and the other is used to hinge the first connecting rod 301 and the second connecting rod. 302 , the ends of the first connecting rod 301 and the second connecting rod 302 are hinged at the two ends of the diagonal line of the board surface of the connecting plate 7 respectively. The ends of the first connecting rod 301 and the second connecting rod 302 facing away from the connecting plate 7 are both bent and disposed, and the bending angle of the second connecting rod 302 is greater than the bending angle of the first connecting rod 301 . In order to prevent the first link 301 and the second link 302 from affecting each other during the movement, the two ends of the second link 302 are hinged on the connecting plate 7 and the higher end of the side diagonal of the connecting piece 6 respectively, and The side diagonals of the connecting plate 7 and the connecting piece 6 are in the same direction; the two ends of the first link 301 and the two ends of the second link 302 are hinged on the same side of the connecting plate 7 and the connecting piece 6, and are located at the above-mentioned diagonal corners the other end of the line. Both ends of the first link 301 and the second link 302 are connected by hinges.

The support rod 401 and the support plate 2 are also connected by hinges. The connection positions of the support rod 401 and the connecting rod assembly 3 and the support plate 2 are located at the upper and lower bottom edges of the support plate 2 respectively, so as to play a stable supporting role for the support plate 2 .

Referring to Figure 3, Figure 4 and Figure 5, it is a structural diagram of the open state of the support plate 2; with reference to Figure 6, it is a state when the support plate 2 is opened or retracted to half; The board is fully retracted. The use process is as follows: the support plate 2 is raised from the floor plane around the link assembly 3, and then descends to the plane of the support block 501 after bypassing the highest point. At the same time, the positioning pin 502 is inserted into the support block 501, and the rotating support rod 401 is inserted into the limit hole 402. , the opening process of the support plate 2 is completed. At this time, the support plate 2 is in an open state to provide upper body support for the submersible observation; the retraction process of the support plate 2 is the opposite. 402 Pull out, and then move the support plate 2 around the connecting rod assembly 3 from the plane of the support block 501 to the gap 101 of the fixed floor 1. At this time, the first connecting rod 301, the second connecting rod 302 and the support rod 401 The cross-folding is stored under the support plate 2, and the support plate 2 is in a retracted state at this time.

The present invention increases the floor area when the support plate 2 is folded, which is convenient for the submersible to change posture; when the support plate 2 is opened, the feet can be extended under the floor to increase the angle of the thigh and the trunk, so that the sitting posture of the human body is more stretched, and the human body is more comfortable. The upper body provides support and greatly increases the working comfort of the submersibles on both sides of the manned submersible's narrow cabin.

The above description is an explanation of the present invention, not a limitation of the present invention. For the limited scope of the present invention, refer to the claims, and any form of modification can be made within the protection scope of the present invention.
