Description

Technical Field

[0001] The present invention relates to the technical field of unpowered diving deceleration devices for submersibles, and in particular to a submersible light shell device with a deceleration function and a use method thereof. Background Art

[0002] In deep-sea exploration, in-situ observation of submersibles sitting on the bottom can effectively improve operational efficiency and increase concealment. In order to enhance the stability of the bottom, the submersible will have a large underwater negative buoyancy. For submersibles with slender rotating bodies, the vertical flow area is small, and it is impossible to effectively slow down, resulting in a faster diving speed. Diving too quickly will cause the flow field near the submersible to be complex, and at the same time cause the submersible to shake and rotate, which has a negative impact on sampling, communication and detection. Using fixed wings to slow down will reduce the diving speed, increase the diving time, and destroy concealment. Therefore, it is necessary to maintain a high speed during the long diving process, while performing intermittent deceleration to obtain a better working state at low speed. During long dives, the motor drives the wing panels to intermittently unfold and actively reduce the speed, which is abnormally energy-consuming and expensive, and cannot be applied to mass production. In order to achieve the above functions, there is no relevant solution yet, and new designs need to be carried out. Summary of the invention

[0003] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a submersible light shell device with a deceleration function and a method of use, so that when the rotating body submersible is diving motionlessly, the light shell can be automatically opened to perform active intermittent deceleration, so as to facilitate the equipment in the cabin to achieve a better working state.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A submersible light shell device with a deceleration function comprises a reset ring, the top surface of the reset ring is evenly spaced with four vertical slide rails, a support ring is installed on the upper part of the slide rails, the support ring is mounted on the outer ring of the slide rails through rollers, four hinges are evenly distributed in the circumferential direction of the support ring, each hinge is installed with a flippable wing plate, and the bottom of a single wing plate is connected to the reset ring through a reset rope assembly.

[0006] Its further technical solution is:

[0007] The slide rail is made of channel steel, and the opening of the channel steel faces outward.

[0008] The roller is arranged in the channel steel and is sleeved on the support ring so as to rotate around the support ring.

[0009] The inner circle diameters of the support ring and the wing plate are larger than the outer circle diameter of the slide rail.

[0010] The support ring adopts a rigid circular ring structure.

[0011] The structure of a single hinged part is as follows: it includes ear plates fixed at intervals on the outer ring of the support ring, a hinge shaft is installed between the two ear plates, a connecting rod is installed in the middle of the hinge shaft, the outer end of the connecting rod is fixed to the wing plate, a torsion spring is installed between the connecting rod and the ear plate, and the torsion spring is sleeved on the hinge shaft.

[0012] The wing plate has negative buoyancy underwater, and is formed by axially cutting a thin-walled cylindrical light shell into four equal parts, and the bottom surface has a round chamfer.

[0013] The reset rope assembly comprises a cable and a winch. The cable is a high-strength light rope, which is fixedly connected to the inner wall surface of the middle part below the wing plate after extending from the winch. The winch is fixed on the reset ring.

[0014] The reset ring is a rigid circular ring.

[0015] A method for using a submersible light shell device with a deceleration function includes the following operation procedures:

[0016] S1: Dive preparation;

[0017] Before the submersible dives, the wing panels are opened at a large angle, and the clamping reset ring is moved downward to achieve position stability and large-angle pre-expansion of the wing panels;

[0018] S2: intermittent deceleration during the dive;

[0019] During the unpowered dive of the submersible, periodic deceleration is achieved. A complete cycle includes the following processes:

[0020] S2.1: deceleration process of wing panel deployment;

[0021] As the diving speed increases, the water flow force pushes the wing plate to gradually expand to the maximum angle of 90°; subject to the damping deceleration of the roller, the wing plate moves up with the entire sliding assembly at a low speed, and the cable releases its length;

[0022] S2.2: Wing plate automatic closing process;

[0023] When the cable is released, the cable suddenly tightens the wing plate, and under the combined action of the upward inertia force of the sliding component and the closing force of the torsion spring, the wing plate closes and is maintained in a closed state by the torsion spring;

[0024] S2.3: the acceleration process of the wing plate moving downward;

[0025] When the wing panels are closed, the submersible begins to move downward at a low speed under the action of its own negative buoyancy, the diving resistance of the submersible decreases, and the diving speed gradually increases;

[0026] S2.4: Wing panel recovery and deployment process;

[0027] When the wing moves down and hits the reset ring, the inertial force causes a collision force, causing the wing to unfold at a large angle again, starting a new cycle.

[0028] The beneficial effects of the present invention are as follows:

[0029] The present invention has a compact and reasonable structure and is easy to operate. Through the cooperation between the slide rails, support rings, wing plates, rollers, reset ropes and other components, the light outer shell can be automatically opened to perform active intermittent deceleration during the motionless dive of the rotating body submersible, so that the equipment in the cabin can reach a better working state. The light outer shell also serves as the deceleration wing and the longitudinal frame also serves as the slide rail, which improves the integration of the equipment, reduces the burden on the equipment, and reduces the overwidth, making it easier to transport and protect. The present invention adopts a design without a pressure-resistant structure and does not require energy and electronic equipment. It is suitable for full-sea depth environments, reduces costs, and improves reliability in long-term service.

[0030] The present invention can perform powerless and continuous intermittent deceleration and opening and closing of the light outer shell during diving, which is convenient for the operation of equipment in the cabin.

[0031] The present invention adopts a design without a pressure-resistant structure, energy source and electronic equipment, is applicable to full-sea depth environments, reduces costs, and improves reliability in long-term service;

[0032] The present invention uses a light shell as a deceleration wing and a longitudinal frame as a slide rail, thereby improving the integration of the equipment, reducing the burden on the equipment, reducing the excess width, and facilitating transportation and protection.

[0044] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0045] like Figure 1-Figure 8 As shown, the submersible light shell device with deceleration function of this embodiment includes a reset ring 7, four vertical slide rails 1 are evenly distributed on the top surface of the reset ring 7, a support ring 2 is installed on the upper part of the slide rail 1, the support ring 2 is sleeved on the outer ring of the slide rail 1 through a roller 3, four hinges 4 are evenly distributed in the circumferential direction of the support ring 2, each hinge 4 is installed with a flippable wing plate 5, and the bottom of a single wing plate 5 is connected to the reset ring 7 through a reset rope assembly 6.

[0046] The slide rail 1 is made of channel steel, and the opening of the channel steel faces outward.

[0047] The roller 3 is arranged in the channel steel, and the roller 3 is sleeved on the support ring 2 and can rotate around the support ring 2.

[0048] The inner diameters of the support ring 2 and the wing plate 5 are larger than the outer diameter of the slide rail 1 .

[0049] The support ring 2 adopts a rigid circular ring structure.

[0050] The structure of a single hinged part 4 is as follows: it includes ear plates 41 fixed at intervals on the outer ring of the support ring 2, a hinge shaft 42 is installed between the two ear plates 41, a connecting rod 44 is installed in the middle of the hinge shaft 42, the outer end of the connecting rod 44 is fixed to the wing plate 5, a torsion spring 43 is installed between the connecting rod 44 and the ear plate 41, and the torsion spring 43 is sleeved on the hinge shaft 42.

[0051] The wing plate 5 has negative buoyancy underwater. The wing plate 5 is formed by axially cutting a thin-walled cylindrical light shell into four equal parts, and the bottom surface has a round chamfer.

[0052] The reset rope assembly 6 includes a cable 61 and a winch 62 . The cable 61 is a high-strength light rope, which extends from the winch 62 and is fixedly connected to the inner wall surface of the middle part below the wing plate 5 . The winch 62 is fixed on the reset ring 7 .

[0053] The reset ring 7 is a rigid ring.

[0054] The method for using the submersible light shell device with deceleration function of this embodiment includes the following operation process:

[0055] S1: Dive preparation;

[0056] Before the submersible dives, the wing plate 5 is opened at a large angle, and the clamping reset ring 7 is moved downward to achieve position stability and large-angle pre-expansion of the wing plate 5;

[0057] S2: intermittent deceleration during the dive;

[0058] During the unpowered dive of the submersible, periodic deceleration is achieved. A complete cycle includes the following processes:

[0059] S2.1: the deceleration process of the wing panel 5 when it is unfolded;

[0060] As the diving speed increases, the water flow force pushes the wing plate 5 to gradually expand to a maximum angle of 90°; subject to the damping deceleration of the roller 3, the wing plate 5 moves up with the entire sliding assembly at a low speed, and the cable 61 is released with the movement;

[0061] S2.2: The wing panel 5 is automatically closed;

[0062] When the cable 61 is released, the cable suddenly tightens the wing plate 5. Under the combined effect of the upward inertia force of the sliding assembly and the closing force of the torsion spring 43, the wing plate 5 is closed and maintained in the closed state by the torsion spring 43.

[0063] S2.3: the wing plate 5 moves downward and accelerates;

[0064] When the wing plate 5 is closed, it starts to move downward at a low speed under the action of its own negative buoyancy, the diving resistance of the submersible is reduced, and the diving speed gradually increases;

[0065] S2.4: The wing panel 5 resumes the deployment process;

[0066] When the wing plate 5 moves downward and touches the reset ring 7, the inertial force induces a collision force and causes the wing plate 5 to be unfolded at a large angle again, starting a new cycle.

[0067] The specific structure and function of the submersible light shell device with deceleration function described in the present invention are as follows:

[0068] It mainly includes a slide rail 1, a support ring 2, a hinge 4, a wing plate 5, a reset rope assembly 6 and a reset ring 7.

[0069] The support ring 2 , the roller 3 , the hinge 4 and the wing plate 5 form a sliding assembly, which can be lifted and lowered vertically on the slide rail 1 .

[0070] There are four sets of slide rails 1, rollers 3, wing plates 5, hinges 4 and reset rope assemblies 6, which are symmetrical about the axis of the rotating body submersible.

[0071] The vertical symmetry planes of the wing plate 5, the hinge 4 and the reset rope assembly 6 coincide with each other and pass through the axis of the submersible.

[0072] The inner diameters of the support ring 2 and the wing plate 5 are larger than the outer diameter of the slide rail 1 .

[0073] The slide rail 1 is fixedly connected to the hull, parallel to the axis of the submersible, and also serves as a longitudinal frame. The slide rail 1 is a channel steel with an opening facing outward.

[0074] The support ring 2 is a rigid circular ring, which is sleeved on the slide rail 1 .

[0075] The roller 3 has its own rolling friction damping, which can effectively reduce speed.

[0076] The roller 3 is fixedly connected to the support ring 2 and can rotate around the support ring 2 .

[0077] The roller 3 is located inside the slide rail 1 and has a squeezing force with the slide rail 1 , and cannot slide, but can only roll up and down along the slide rail 1 .

[0078] The hinge member 4 includes an ear plate 41 , a hinge shaft 42 , a torsion spring 43 and a connecting rod 44 .

[0079] The ear plate 41 is installed outside the supporting ring 2 .

[0080] The hinge shaft 42 is horizontally connected to the inner sides of the two ear plates 41 .

[0081] The torsion spring 43 is sleeved on the hinge shaft 42, and its two ends are respectively fixed on the ear plate 41 and the connecting rod 44. The torsion spring 43 has an initial torsion force for closing the wing plate 5.

[0082] The upper part of the connecting rod 44 is sleeved on the hinge shaft 42 through a through hole, and the lower part is fixedly connected to the middle part of the outer surface above the wing plate 5. When the wing plate 5 is unfolded 90 degrees, the upper end of the connecting rod 44 is just pressed on the supporting ring 2 to achieve the angle limit.

[0083] The wing plate 5 has negative buoyancy underwater and is formed by cutting a thin-walled cylindrical light shell into four equal parts axially, and has a rounded chamfer on the bottom surface.

[0084] The reset rope assembly 6 includes a cable 61 and a winch 62 .

[0085] The cable 61 is a high-strength light rope, which extends from the winch 62 and is fixedly connected to the inner wall surface of the middle part below the wing plate 5.

[0086] The winch 62 is fixed on the reset ring 7, exerting a certain pulling force on the cable 61 to maintain the cable 61 in a taut state. When the pulling force of the cable 61 is large, the cable is released. When the cable 61 is released, the cable 61 will be instantly taut.

[0087] The reset ring 7 is a rigid circular ring, fixedly connected to the slide rail 1, with an outer diameter the same as that of the wing plate 5, and a chamfered upper outer edge.

[0088] In actual use, it is completed through the following steps:

[0089] S1: Dive preparation;

[0090] Before the submersible dives, the wing plate 5 is opened at a large angle by external force, and the sliding assembly moves downward under the action of its own gravity. Under the action of the torsion spring 43, the wing plate 5 has a clamping force on the reset ring 7, so as to achieve the stability of the position and the large-angle pre-expansion of the wing plate 5.

[0091] S2: Unpowered intermittent deceleration diving process. After the submersible is launched into the water, it dives unpowered under the action of its own negative buoyancy and enters the intermittent deceleration diving process, including the following steps:

[0092] A: Deceleration process of wing panel 5 unfolding;

[0093] As the diving speed increases, the thrust of the ocean current on the wing plate 5 increases.

[0094] The roller 3 has a squeezing friction with the slide rail 1, and under the effect of its own damping, it can only roll upward at a low speed, causing the entire sliding assembly to move upward at a low speed.

[0095] Under the push of the ocean current, the wing plate 5 is gradually unfolded. When it is unfolded to 90°, the upper end of the connecting rod of the wing plate 5 is pressed on the support ring 2 to limit further rotation, thereby achieving the stability of the angle of the wing plate 5.

[0096] Afterwards, the wing plate 5 moves upward with the sliding assembly, and generates an upward friction force on the slide rail 1 through the roller 3, thereby decelerating the submersible.

[0097] The cable 61 is connected to the wing panel 5 and its length is released as the wing panel 5 is unfolded and moved upward.

[0098] B: The automatic closing process of the flap 5;

[0099] After the cable 61 is released, the wing 5 is suddenly tightened. When the wing 5 is fully deployed, the diving speed of the submersible is reduced, so the closing force required for the wing 5 is also reduced. Since the sliding component has a large upward kinetic energy, it will produce a large impact tension on the cable 61, causing the opening angle of the wing 5 to decrease. After the opening angle of the wing 5 is reduced, the windward area is reduced, and the hydrodynamic deployment force is also greatly reduced. Under the closing force of the torsion spring 43 and the tension of the cable 61, the wing 5 is automatically closed, and the torsion spring 43 maintains the closed state.

[0100] C: The downward movement process of the wing plate 5;

[0101] When the wing plate 5 is closed, the hydrodynamic thrust on the sliding assembly disappears. The sliding assembly begins to slide down under the action of its own negative buoyancy, and is limited in speed by the roller 3, maintaining a certain speed to move downward.

[0102] D: The wing panel 5 resumes the deployment process;

[0103] When the wing plate 5 moves downward and touches the reset ring 7, the impact force causes the wing plate 5 to unfold because the contact position between the lower edge of the wing plate 5 and the upper edge of the reset ring 7 has opposite chamfers. When the wing plate 5 is unfolded at a small angle, the closing force of the torsion spring 43 is small, so the impact force is sufficient to cause the wing plate 5 to unfold at a larger angle.

[0104] The unfolding angle of the wing plate 5 generated by the collision is sufficient to cause the hydrodynamic force on the wing plate 5 to push the wing plate 5 to unfold again, until the wing plate 5 unfolds to 90° and turns to move upward, starting a new deceleration cycle.

[0105] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
