With the continuous progress of the domestic navy's vibration and noise reduction technology, the level of acoustic stealth of domestic ships has made great progress. Especially with the application of a series of new materials and new technologies on the ship, the corrosion resistance and maintenance conditions of the ship have been greatly improved. Due to the weight limitation of the steel enclosure door, the thickness of the steel plate cannot be too thick, so the stiffness is small and vibration noise problems are easy to occur. The steel enclosure door cannot be covered with sound-absorbing tiles, so it no longer meets the low acoustic characteristic requirements of the enclosure as a whole. At the same time, the steel enclosure door is prone to corrosion, which is not conducive to the maintenance of the enclosure door. SUMMARY

In addition, the terms "first", "second" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0050] The present application proposes a mechanical transmission flip-up opening type conformal surrounding shell door.

[0051] Reference Figures 1 to 1 1. In the preferred embodiment, a mechanical transmission flip-up opening type conformal surrounding shell door comprises a composite material door panel 1, a door frame 2 and a transmission mechanism 3 for driving the composite material door panel 1 to open or close, the composite material door panel 1 is a double-curved surface saddle-shaped structure, the composite material door panel 1 comprises an outer shell 11 made of glass fiber reinforced vinyl composite material (i.e. formed after pouring vinyl resin with glass fiber cloth), a steel framework 12 located inside the cavity of the outer shell 11 and an anti-sound type hard PVC foam 13 filled in the cavity of the outer shell 11.

[0052] Specifically, in the present embodiment, referring to Figures 3a to 3e , the steel framework 12 comprises one border, two horizontal T-shaped rib plates and two vertical T-shaped rib plates.

[0053] Further, referring to Figure 5 and Figure 6The preformed composite reinforcing block 14 is made of glass fiber reinforced vinyl composite material and is made by hand (formed by pouring vinyl resin into multiple layers of glass fiber cloth to form the preformed composite reinforcing block 14) and is attached to the steel framework 12 after being ground and polished and is a transition structure between the anti-sound type rigid PVC foam 13 and the steel framework 12.

[0054] Specifically, referring to Figure 5 and Figure 6 , the front and rear ends of the steel framework 12 are respectively attached to the inner side walls of the shell 11, and the front and rear ends of the anti-sound type rigid PVC foam 13 are respectively attached to the inner side walls of the shell 11, the gaps at the above-mentioned attachment points are filled with vinyl resin and are integrally formed, and together constitute the main body structure of the composite door panel 1.

[0055] The preformed composite reinforcing block 14 is made of glass fiber reinforced vinyl composite material and is made by hand (formed by pouring vinyl resin into multiple layers of glass fiber cloth to form the preformed composite reinforcing block 14) and is attached to the steel framework 12 after being ground and polished and is a transition structure between the anti-sound type rigid PVC foam 13 and the steel framework 12.

[0056] Specifically, in this embodiment, referring to Figure 9 , the transmission mechanism 3 is a worm gear transmission mechanism, which includes a bracket 31 fixedly connected to the composite door panel 1, a rotating shaft 32 penetrating through the bracket 31, a bearing seat 33 for supporting the rotating shaft 32 to rotate, a worm gear 34 sleeved on the rotating shaft 32, and a worm 35 engaged with the worm gear 34, rotating the worm 35 to drive the worm gear 34 to rotate and in turn drive the composite door panel 1 to open or close.

[0057] Specifically, in this embodiment, the worm 35 is supported on the fixed seat and rotates relative thereto, and a hand wheel 36 is fixedly connected to the end of the worm 35.

[0058] The worm wheel 34, the rotating shaft sleeve 37 and the rotating shaft 32 are connected by means of a key connection, which ensures reliable torque transmission. The rotating shaft 32 and the bearing seat 33 are connected by means of a sleeve, which reduces friction. When the hand wheel 36 is rotated, the worm 35 rotates through two bearings, one of which is a thrust bearing and the other of which is a rolling bearing. Both bearings are provided with oil injection holes for injecting lubricating oil to reduce friction. The bracket 31 and the steel framework 12 of the composite door panel 1 are connected by means of bolts. When the hand wheel 36 is rotated, the worm 35 drives the worm wheel 34 and the rotating shaft 32 to rotate, and then drives the composite door panel 1 to rotate through the rotating shaft sleeve 37 and the bracket 31, thereby achieving the opening and closing of the composite door panel 1. The bearing seat 33 and the worm mechanism are connected to the steel structure of the enclosure by means of bolts. In order to prevent the composite door panel 1 from falling accidentally during the opening and closing process, the transmission mechanism 3 is designed to be self-locking (self-locking can be achieved when the helix angle of the worm 35 is smaller than the friction angle of the worm 35 contacting the worm wheel 34), that is, the opening and closing of the composite door panel 1 can only be controlled by rotating the hand wheel 36, and the composite door panel 1 will not automatically fall back due to gravity, thereby ensuring safety.

[0059] The enclosure door adopts a worm wheel 34 and worm 35 mechanical transmission mode to realize the everted opening of the composite door panel 1. Mechanical transmission has the advantages of convenience and reliability, which is beneficial to maintenance during service.

[0060] Further, with reference to Figure 10a and Figure 10b , the mechanical transmission everted opening type conformal enclosure door further comprises a stop mechanism 4 for limiting the rotation angle of the composite door panel 1. The stop mechanism 4 comprises a limiting block 41 fixed to the rotating shaft 32 and a limiting baffle 42 fixed to the bearing seat 33. The limiting baffle 42 limits the limiting block 41 to limit the rotation angle of the rotating shaft 32.

[0061] By providing the stop mechanism 4, the composite door panel 1 is prevented from colliding with the door frame 2 when the opening angle is too large, thereby preventing the composite door panel from being worn.

[0062] Further, with reference to Figure 11a , Figure 11b , the mechanical transmission everted opening type conformal enclosure door further comprises a locking mechanism 5 for locking the composite door panel 1 to the door frame 2. The composite door panel 1 is fixed with a locking block 15, and a recess is formed in the locking block 15. The locking mechanism 5 comprises a guide frame 51 fixed to the door frame 2, a seat plate 52 in sliding connection with the guide frame 51, a handle 53 installed on the seat plate 52 and hinged thereto, a lock cylinder 54 and a lock rod 56 installed on the handle 53, and a pin shaft 55 installed on the seat plate 52. The lock rod 56 can be pulled into the recess of the locking block 15 to lock the door panel. Two locking mechanisms 5 can be provided at the position of the cross ribs of the enclosure door.

[0063] The handle 53 rotates around the pin shaft 55. When locking, the lock rod 56 is pulled into the groove of the lock block 15, and the handle 53 is rotated. When the center of the lock rod 56 is just above the center of the pin shaft 55, the locking is achieved. When opening, the handle 53 is rotated in the opposite direction. When the center of the lock rod 56 is just above the center of the pin shaft 55, the lock rod 56 is separated from the groove of the lock block 15, and the opening is achieved. Then, the seat plate 52 is slid along the guide frame 51 to the other end to avoid affecting the passage of people.

[0064] When the enclosure door is from the closed state to the open state, the following steps can be taken:

[0065] 1. Open the locking mechanism 5 (two places). Rotate the handle 53, and the lock rod 56 is separated from the lock block 15 on the composite door plate 1. Slide the seat plate 52 along the guide frame 51 to the other end of the guide frame 51.

[0066] 2. Open the composite door plate 1. Rotate the hand wheel 36 clockwise, and the force moment is transmitted through the worm 35 and the worm gear 34. The composite door plate 1 rotates around the rotating shaft 32 to open. The opening speed is determined by the rotation speed of the hand wheel 36.

[0067] When the enclosure door is from the open state to the closed state, the following steps can be taken:

[0068] 1. Close the composite door plate 1. Rotate the hand wheel 36 counterclockwise, and the force moment is transmitted through the worm 35 and the worm gear 34. The composite door plate 1 rotates around the rotating shaft 32 to close. The opening speed is determined by the rotation speed of the hand wheel 36.

[0069] 2. Lock the locking mechanism 5. Slide the seat plate 52 along the guide frame 51 to connect the lock rod 56 to the lock block 15 on the composite door plate 1. Rotate the handle 53 to tighten the lock rod 56, and lock the composite door plate 1.

[0070] The mechanical transmission flip-up type conformal enclosure door proposed in this embodiment has the following beneficial effects:

[0071] 1. The enclosure door is located at the bow of the submarine command room enclosure, and is the passage for personnel to enter and exit the command room enclosure. The structure line of the bow requires the outer line of the enclosure door to match it. The composite door plate 1 adopts a double-curved saddle-shaped structure design, which conforms to the shape of the enclosure door on the one hand and reduces the flow resistance on the other hand.

[0072] 2. The door plate adopts a steel skeleton 12 + composite material structure design, which has excellent sound reflection characteristics. On the one hand, the composite door plate 1 has sound reflection characteristics, which matches the acoustic index of the command room enclosure.

[0073] 3. Since the enclosure door is in a complex use environment of dry and wet alternation and pressure alternation, the components of the enclosure door are made of corrosion-resistant materials such as composite materials and stainless steel, which improves the maintenance conditions.

[0074] 4、Door plate adopts steel skeleton 12+ composite material structure design, has big potential depth water pressure bearing capacity, door plate structure strength and rigidity has greater promotion compared with original steel door, front can bear 0.1MPa single side load, and its structure strength can bear the impact of wave load.

[0077] A steel jig is manufactured according to the theoretical line shape of the door plate, and the steel skeleton 12 of the door plate is manufactured by segmental butt welding on the steel jig after the steel jig passes the line shape inspection;

[0078] After the steel skeleton 12 passes the line shape inspection, surface rust, welding slag and oil stains are removed, and the steel skeleton 12 is cleaned with acetone and dried;
