Description

Technical Field

[0001] The present invention relates to the technical field of hatch cover locking, in particular to a hatch cover locking device for a deep-sea manned submersible. Background Art

[0002] Deep-sea manned submersibles are essential tools for exploring the depths of the ocean, and the locking mechanism of their hatches is directly related to the safety and reliability of the submersible. In extreme deep-sea environments such as high pressure, low temperature, and severe corrosion, the hatches must be able to lock tightly to prevent seawater from seeping in and protect the lives of divers.

[0003] The submersible needs to lock the hatch cover when diving. When the hatch cover and the hatch are locked by the rotating barrel bolt and the buckle, the direction of the submersible changes constantly when diving underwater, which makes the hatch cover easily affected by the constant changes in the water flow and the erosion of the hatch cover. When diving, the bolts and buckles locking between the hatch cover and the hatch are easily loosened or the locking force is weakened due to the constant erosion of the water flow, which affects the locking strength between the hatch and the hatch cover and the sealing after locking.

[0038] The present invention has the following beneficial effects:

[0039] 1. The present invention, through the opening and closing assembly, the elastic assembly and the auxiliary mechanism, when the diving depth of the submersible continues to increase, the pressure in the water will continue to increase. At this time, the rubber layer will produce an upward deformation in the top cover under the action of the water pressure as the diving depth and pressure increase. At this time, the sliding of the L rod will make the L rod contact the inner wall of the main body, thereby forming a blocking force between the hatch cover and the main body, which can increase the locking force between the hatch cover and the main body, so that the hatch cover can automatically increase the locking force between the hatch cover and the main body as the water pressure increases, so that the locking force of this device can be stronger as the water depth increases, thereby reducing the situation where the locking force of the bolts on the hatch cover is loosened or weakened due to the continuous changes and impacts of the flow direction and pressure in the water when the submersible dives and navigates in the water, thereby further enhancing the locking strength when locked.

[0040] 2. The present invention, through the fixing component and the shaking component, can make the straight groove frame stuck in the groove on one side of the tooth groove when pushed by the inclined rectangular plate. The engagement between the straight groove frame and the tooth groove can keep the rectangular plate stable in position during the navigation of the submarine, thereby reducing the situation in which the rectangular plate and the square frame drive the rubber layer to slide downward and reset under the flow of water when the submarine dives non-vertically, and reduces the situation in which the locking strength is constantly changing due to the possible reset and the rectangular plate driving the straight groove frame to shake up and down under the flow of water, thereby further maintaining the stability of the locking force between the hatch cover and the main body while ensuring the stability of the position of the square frame and the rectangular plate when the submarine is sailing at any angle and when the water flows.

[0041] 3. In the present invention, the disc squeezes the water inside the hollow cylinder through the fixed component and the sliding component when it moves downward. At this time, the disc can be blocked by the resistance of the water in the hollow cylinder and it is difficult to slide downward, thereby reducing the situation where the rubber layer and the square frame lose the locking force between the hatch cover and the main body as the pressure decreases when the submersible surfaces. This ensures the locking force between the hatch cover and the main body when the submersible surfaces, while reducing the resetting of the L rod when the submersible surfaces, thereby ensuring the locking force of the submersible when diving in deep water.

[0042] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] Auxiliary mechanism 2, which is installed on the top of the main body 1 and is used to enhance the locking strength of the main body 1;

[0057] The sliding mechanism 3 is mounted on the outer surface of the auxiliary mechanism 2 to ensure the stability of the main body 1 when it is locked;

[0058] The top of the main body 1 is hinged with a hatch cover 101, and the top of the hatch cover 101 is bolted to a top cover 111. A rubber layer 121 is fixedly connected to the inside of the top cover 111. A curved elastic disk 122 is provided on the top of the rubber layer 121. The top of the curved elastic disk 122 is fixedly connected to the top inner wall of the top cover 111.

[0059] The locking of the main body 1 by the auxiliary mechanism 2 can be combined with the sliding mechanism 3 to enhance the locking strength of the main body 1 under the pressure of water pressure during diving.

[0060] Body 1 includes:

[0061] An opening and closing component 11 is installed on the top of the main body 1;

[0062] The elastic component 12 is installed inside the opening and closing component 11;

[0063] The locking assembly 13 is installed at the bottom of the opening and closing assembly 11 through a flip piece.

[0064] The auxiliary mechanism 2 includes a hollow cylinder 201 fixedly connected to the inner wall of the top of the hatch cover 101. The auxiliary mechanism 2 includes:

[0065] The fixing assembly 21 is installed on the top of the hatch cover 101;

[0066] Sliding component 22, the sliding component 22 is installed on the outer surface of the fixed component 21;

[0067] The translation assembly 23 is installed at the bottom of the sliding assembly 22 .

[0068] The sliding mechanism 3 includes a square frame 301 slidably arranged at the bottom of the top cover 111. The sliding mechanism 3 includes:

[0069] The shaking assembly 31 is installed on the side wall of the square frame 301.

[0070] The opening and closing assembly 11 includes a plurality of oblique slots 112 formed on the outer surface of the hatch cover 101;

[0071] The outer surface of the top cover 111 is provided with a plurality of rectangular grooves 113 , and the interior of the hatch cover 101 is provided with a plurality of L-grooves 114 ;

[0072] The elastic component 12 includes an annular groove 123 formed on the top outer wall of the hatch cover 101. When the hatch cover 101 and the main body 1 are closed, the adjusting frame 131 is rotated to cause the triangular plate 132 to slide downward. When the triangular plate 132 slides downward, the locking frame 134 is pushed to rotate through the intermediate rod 133.

[0073] The flip member includes an adjustment frame 131 rotatably connected to the top inner wall of the hatch cover 101;

[0074] A plurality of guide rods are fixedly connected to the inner wall of the top of the hatch cover 101, and a triangular plate 132 is slidably connected to the outer surface of the guide rod, and the triangular plate 132 is threadedly connected to the outer surface of the adjustment frame 131;

[0075] The locking assembly 13 includes a plurality of intermediate rods 133 rotatably connected to the outer surface of the triangular plate 132. The end of the intermediate rod 133 away from the triangular plate 132 is rotatably connected to a locking frame 134. The top of the locking frame 134 is rotatably connected to the top inner wall of the hatch cover 101. When the submersible is locked and dives into the water, the water around the submersible will enter the top cover 111 through multiple inclined holes 112 and rectangular grooves 113 as the submersible dives deeper. Then, as the submersible dives deeper, the pressure in the water will continue to increase. At this time, the rubber layer 121 will produce an upward deformation in the top cover 111 under the action of the water pressure as the diving depth and pressure increase.

[0076] The fixing assembly 21 includes a rectangular column 211 fixedly connected to the outer wall of the top of the hatch cover 101. The interior of the rectangular column 211 is hollow, and the interior of the rectangular column 211 is connected to the interior of the hollow cylinder 201.

[0077] The left and right sides of the rectangular column 211 are both provided with tooth grooves 212, and a T-shaped rod 213 is slidably connected between the two tooth grooves 212;

[0078] The two tooth grooves 212 are connected, and the inclined ring 222 generates an oblique lateral pushing force on the side walls of the multiple L rods 231 when sliding. At this time, the multiple L rods 231 will slide outward in the L groove 114 after being pushed.

[0079] The sliding assembly 22 includes connecting rods 221 fixedly connected to the front and back of the T-shaped rod 213, and the ends of the two connecting rods 221 away from the T-shaped rod 213 are fixedly connected to the tilting ring 222;

[0080] Among them, a disc 223 is provided at the bottom of the inclined ring 222, and the disc 223 is fixedly connected to the bottom outer wall of the T-shaped rod 213. The side wall of the disc 223 is provided with a plurality of tapered holes. When the rubber layer 121 is deformed upward under the action of water pressure and drives the T-shaped rod 213 to rise, the rise of the T-shaped rod 213 can enable the water flow to pass through the multiple tapered holes and enter between the bottom of the disc 223 and the hollow cylinder 201. Later, when the submersible floats up and the surrounding pressure decreases, the arc-shaped elastic disc 122 will push the rubber layer 121 to reset as the pressure decreases under the release of its own elastic potential energy.

[0081] The translation assembly 23 includes a plurality of L-shaped rods 231 slidably connected to the top outer wall of the hatch cover 101 , and one end of the L-shaped rod 231 away from the rectangular column 211 is slidably connected to the inside of the L-shaped groove 114 ;

[0082] Among them, the end of the L rod 231 away from the rectangular column 211 is fixedly connected to the spring plate 232, and the end of the L rod 231 close to the spring plate 232 is fixedly connected to the horizontal plate 233. The downward sliding of the square frame 301 will drive the T-shaped rod 213 and the disc 223 to move downward synchronously. When the disc 223 moves downward, it will squeeze the water inside the hollow cylinder 201. At this time, when the water inside the hollow cylinder 201 is squeezed by the disc 223, only a very small part of the water will flow outward through the small holes in the tapered hole.

[0083] The square frame 301 is slidably connected to the outer surface of the rectangular column 211 , and the top of the square frame 301 is fixedly connected to the bottom of the rubber layer 121 ;

[0084] The shaking assembly 31 includes a rectangular plate 311 rotatably connected to the left and right sides of the square frame 301 , and two connecting bars 312 are rotatably connected to the bottom of the rectangular plate 311 ;

[0085] A straight slot frame 313 is rotatably connected between the two connecting bars 312 , and the straight slot frame 313 is slidably connected to the outer surface of the T-shaped rod 213 ;

[0086] A return spring is fixedly connected to the inside of the straight groove frame 313. One end of the straight groove frame 313 is fixedly connected to the outer wall of the T-shaped rod 213 under the pressure of the return spring. When the straight groove frame 313 is pushed by the inclined rectangular plate 311, it can be stuck in the groove on one side of the tooth groove 212. Through the engagement between the straight groove frame 313 and the groove of the tooth groove 212, the rectangular plate 311 can maintain a stable position during the navigation of the submarine.

[0087] During use, when the hatch cover 101 and the main body 1 are closed, the triangular plate 132 slides downward by rotating the adjusting frame 131. When the triangular plate 132 slides downward, the locking frame 134 is pushed to rotate through the intermediate rod 133. When multiple locking frames 134 rotate, they will be stuck on the inner wall of the main body 1. Then, by continuing to rotate the adjusting frame 131, the locking frame 134 can firmly lock the hatch cover 101 and the main body 1, thereby completing the locking purpose.

[0088] When the submersible is locked and dives into the water, the water around the submersible will enter the top cover 111 through the multiple inclined holes 112 and the rectangular grooves 113 as the submersible dives deeper. Then, as the submersible dives deeper, the pressure in the water will continue to increase. At this time, the rubber layer 121 will produce an upward deformation in the top cover 111 under the action of the water pressure as the diving depth and pressure increase. When the rubber layer 121 deforms, it will push the arc-shaped elastic disk 122 to slide upward. When the rubber layer 121 deforms upward, it will drive the square frame 3 01 and the rectangular plate 311 slide upward, and at this time the bottom of the rectangular plate 311 will also slide upward under the inflow of water. When the square frame 301 and the rectangular plate 311 slide upward, the straight groove frame 313 will be driven to rise through the connecting bar 312. Then, when the straight groove frame 313 rises, the inclined ring 222 will be driven to slide synchronously through the connecting rod 221. When the inclined ring 222 slides, it will generate an oblique lateral driving force on the side walls of the multiple L rods 231. At this time, the multiple L rods 231 will slide outward in the L groove 114 after being pushed. At this time, the sliding of the L rods 231 will The L rod 231 is in contact with the inner wall of the main body 1, and when the L rod 231 continues to slide, the spring plate 232 can be compressed, so that the spring plate 232 is in close contact with the inner wall of the main body 1, thereby increasing the locking strength. At the same time, when the L rod 231 slides, the cross plate 233 is inserted into the groove of the inner wall of the main body 1, thereby forming a blocking force between the hatch cover 101 and the main body 1. At the same time, as the diving depth and water pressure continue to increase, the deformation force of the rubber layer 121 will increase, thereby being able to pass through the spring plate 232 and the cross plate 233. The blocking of the inner wall of the main body 1 can increase the locking force between the hatch cover 101 and the main body 1, so that the hatch cover 101 can automatically enhance the locking force with the main body 1 as the water depth pressure increases, so that the locking force of this device becomes stronger as the water depth increases, thereby reducing the situation in which the locking force of the bolts on the hatch cover 101 becomes loose or weakened due to the continuous changes and impacts of the flow direction and pressure in the water when the submersible dives and navigates in the water, thereby further enhancing the locking strength during locking.

[0089] When the submersible is performing a non-vertical diving movement, causing the water around the submersible to flow through multiple inclined slots 112 and the inclined slots 112 in the top cover 111, the rectangular plate 311 can rotate when the water flows. When the rectangular plate 311 rotates, the straight slot frame 313 is pushed by the connecting bar 312 to slide horizontally on the surface of the T-bar 213 and stretch the internal reset spring. When the straight slot frame 313 is pushed by the inclined rectangular plate 311, it can be stuck in the groove on one side of the tooth groove 212. The engagement of the straight slot frame 313 with the groove of the tooth groove 212 can make the rectangular plate 311 maintains a stable position during the navigation of the submarine, thereby reducing the possibility of the rectangular plate 311 and the square frame 301 sliding downward and resetting under the flow of water when the submarine dives non-vertically, and reducing the possibility of resetting when the water flows and the rectangular plate 311 driving the straight groove frame 313 to swing up and down under the flow of water, resulting in continuous changes in the locking strength, thereby further maintaining the stability of the locking force between the hatch cover 101 and the main body 1 while ensuring the stability of the position of the square frame 301 and the rectangular plate 311 when the submarine navigates at any angle and when the water flows.

[0090] Since the strength of the hatch cover 101 under the water pressure is also reduced when the submersible surfaces, when the water flows into the interior of the top cover 111 through the multiple inclined holes 112 and the rectangular grooves 113, the water flows into the interior of the rectangular column 211 and the hollow cylinder 201 through the tooth grooves 212. When the rubber layer 121 is deformed upward under the action of water pressure and drives the T-shaped rod 213 to rise, the rise of the T-shaped rod 213 can allow the water to pass through the multiple tapered holes and enter between the bottom of the disc 223 and the hollow cylinder 201. Later, when the submersible surfaces and the surrounding pressure decreases, the arc-shaped elastic disc 122 will push the rubber layer 121 to reset as the pressure decreases due to the release of its own elastic potential energy. When the rubber layer 121 drives the square frame 301 to reset, the downward sliding of the square frame 301 will drive the T-shaped rod 213 and the disc 223 to move downward synchronously, and the disc 223 will squeeze when it moves downward. The water inside the hollow cylinder 201 is compressed. At this time, when the water inside the hollow cylinder 201 is squeezed by the disc 223, only a very small part of the water will flow outward through the small holes in the tapered hole. At this time, most of the water will be blocked by the disc 223 and it will be difficult to flow outward through the tapered hole. At this time, the disc 223 can be blocked by the resistance of the water in the hollow cylinder 201 and it will be difficult to slide downward, thereby blocking the downward force of the square frame 301 when it floats up, and further reducing the situation where the rubber layer 121 and the square frame 301 lose the locking force between the hatch cover 101 and the main body 1 as the pressure decreases when the submersible floats up, thereby ensuring that the locking force between the hatch cover 101 and the main body 1 is ensured when the submersible floats up, while reducing the situation where the L rod 231 is reset when the submersible floats up, thereby ensuring the locking force of the submersible when diving in deep water.

[0091] When the submersible floats to the surface, the water inside the top cover 111 will be discharged outward through the inclined hole groove 112 and the rectangular groove 113. At this time, the elastic potential energy on the arc-shaped elastic disk 122 will be completely released. The potential energy released at this time can further push the disc 223 downward, so that the disc 223 can completely discharge the water in the hollow cylinder 201 when the pressure disappears during the floating process at a height close to the water surface, so that the square frame 301 can be reset.
