Description

Technical Field

[0002] The polar environment is complex and changeable, and submarine detector accidents occur frequently in icy waters. When a submarine safety accident occurs, it is difficult to rescue it in time without special rescue equipment, which can easily cause casualties.

[0003] At present, the environment in which submarines operate underwater can usually be divided into three areas, namely shallow water, sub-deep water and deep water. If a submarine crashes and sinks in deep water, the submarine's pressure body may be destroyed by the sea water pressure in a very short time, and the people on board will have no hope of survival.

[0004] Therefore, it is very necessary to strengthen the research on submarine rescue means and technologies. For the problem of submarine underwater rescue, it is generally achieved through a life-saving submersible, that is, a life-saving submersible is a diving device that can maneuver underwater. It is manually operated to dock with the rescue platform of the crashed submarine to form a channel to transfer the crew in the crashed submarine to the deep-diving lifeboat and then transfer it to the mother ship. When a submarine crashes in the polar region, the existing life-saving submersible returns to the mother ship after the underwater rescue is successful. Due to the obstruction of the ice area, it is difficult for the life-saving submersible to break the ice and surface smoothly, which increases the difficulty of external rescue and greatly affects the underwater rescue effect.

[0022] Preferably, the auxiliary ice-breaking assembly support portion includes a docking ring 6306, two vertical plates 6307, and two limiting rods 6308; The two limiting rods 6308 are fixedly arranged on both sides of the transmission rod 621, one end of the limiting rod 6308 is fixedly arranged on the bottom surface of the side where the housing 62 is connected to the docking seat 61, and the axis of the limiting rod 6308 is parallel to the axis of the transmission rod 621; The docking ring 6306 is sleeved on the outside of the transmission rod 621, and the docking ring 6306 is rotatably connected to the end of the rotating cylinder 6304 away from the docking seat 61; One end of the two vertical plates 6307 is connected to the two limiting rods 6308 respectively, and the other ends of the two vertical plates 6307 are fixedly connected to the docking ring 6306.

In this embodiment, a limiting hole is provided on the vertical plate 6307, so that the limiting rod 6308 can pass through the limiting hole to realize the reciprocating movement of the vertical plate 6307 along the axis of the transmission rod 621. Among them, one end of the limiting rod 6308 is fixedly connected to the inside of the shell, so as to realize the stable lateral movement guide cooperation. At the same time, through the combination of the limiting rod and the vertical plate, the docking ring is in a static state, and is driven by the reciprocating lateral movement of the rotating drum to realize the synchronous reciprocating lateral movement.

[0023] Preferably, the ice-breaking cutting plate driving unit includes a limiting sleeve 6311, a connecting plate 6312, a first connecting rod 6313, a vertical pipe 6314, a compression spring 6315, a second connecting rod 6316, and a moving shell 6317; The limiting sleeve 6311 is fixedly connected to the side wall surface at the top of the shell 62, and the axis of the limiting sleeve 6311 is perpendicular to the axis of the transmission rod 621; the first connecting rod 6313 is coaxially arranged inside the limiting sleeve 6311, and the first connecting rod 6313 passes through the side wall surface at the top of the shell 62, and is fixedly connected to the icebreaking cutting plate 64 through the connecting plate 6312; wherein, the connecting plate and the icebreaking cutting plate are fastened by bolts, and the setting of the icebreaking cutting plate is used for auxiliary telescopic impact icebreaking for inclined buoyancy, thereby enhancing the inclined buoyancy effect of the lifesaving submersible.

[0024] One end of the vertical pipe 6314 is sleeved inside the limiting sleeve 6311 and is coaxially arranged with the limiting sleeve 6311; a compression spring 6315 and a damper 63111 coaxial with the vertical pipe 6314 are arranged inside the vertical pipe 6314; The other end of the first connecting rod 6313 extends into the interior of the vertical pipe 6314 and is fixedly connected to one end of the compression spring 6315; the other end of the compression spring 6315 is fixedly connected to the damper 63111; the other end of the damper is fixedly connected to the second connecting rod 6316; through the energy dissipation cooperation between the damper and the compression spring, the counter-impact force of impact breaking ice can be reduced.

[0026] The other end of the second connecting rod 6316 extends into the first guide groove 6318 and is rotatably connected to the roller 63100; Specifically, when the movable shell 6317 moves along the axial direction of the transmission rod 621 , the roller can move along the second guide groove, so that the second connecting rod 6316 can move along the axial direction of the limiting sleeve 6311 , thereby making the icebreaking cutting plate 64 approach or move away from the shell 62 .

[0027] Preferably, the auxiliary ice-breaking assembly 63 further includes a docking tube 632; The docking tube 632 is disposed inside the housing 62, and the docking tube 632 is rotatably connected to the bottom surface of the housing 62 connected to the docking seat 61; Two guide grooves 633 are symmetrically arranged on the inner wall surface of the docking tube 632; the center plane of the two guide grooves 633 is the plane where the axis of the transmission rod 621 is located; A limiting ring 634 coaxial with the transmission rod 621 is fixedly provided on the transmission rod 621; Two protrusions 635 are symmetrically arranged on the outer wall of the limiting ring 634; The two protrusions 635 are slidably connected to the two guide grooves 633 respectively; The docking tube 632 is fixedly connected to the rotating shaft 611; When the driving shaft inside the front cabin 2 drives the rotating shaft 611 to rotate, the rotating shaft drives the docking cylinder 632 to rotate synchronously, and then through the cooperation of the protrusion 635 and the guide groove 633, the transmission rod rotates synchronously. When the transmission rod rotates, the rotating cylinder 6304 fixed on the transmission rod rotates, and then due to the cooperation between the convex shaft 6303 and the convex shaft groove 6305, the rotating cylinder 6304 can reciprocate along the axial direction of the transmission rod 621, so that the auxiliary icebreaking assembly support part can reciprocate along the axial direction of the transmission rod 621.

[0028] Preferably, the auxiliary ice-breaking assembly support further includes a fixing plate 640; The fixing plate 640 is disposed inside the shell 62 , and one end of the fixing plate 640 is fixedly connected to the bottom surface of the shell 62 away from the docking seat 61 ; the other end is fixedly connected to the outer wall surface of the limiting sleeve 6311 .

[0029] Preferably, the cross-sectional area of ​​the ice-breaking drill bit 65 gradually increases from the side connected to the impact head 66 to the side connected to the transmission rod 621, so that the ice-breaking drill bit is cone-shaped as a whole, and the impact head is located in the direction of the cone head.

[0030] In this embodiment, when carrying out rescue activities, the propulsion system 4 is used to achieve movement and adjustment of the travel direction, so that the life-saving submersible can quickly move to the wrecked submarine to be rescued, and dock with the life-saving platform of the wrecked submarine through the docking skirt 5 to form a hard seal and equalize the pressure with the interior of the submarine. After docking, the life-saving submersible of this embodiment and the internal pressure of the wrecked submarine are balanced by pumping water, thereby establishing a life-saving transfer channel. In this way, the crew of the wrecked submarine can be transferred to the interior of the cabin 1, and then transferred to the lifeboat by the lifeboat. Secondly, during the rescue journey or rescue process, the staff can observe the external environment through the observation window 7 and the side windows set on the side of the front cabin to ensure the accuracy of the travel route and the subsequent intuitive observation of the icebreaking rescue situation.

[0031] The ice breaking device 6 in this embodiment includes a docking seat 61 fixedly connected to the front cabin body 2, a shell 62 fixedly connected to the docking seat 61 for protecting and cooperating with internal parts, and a rotating shaft 611 connected to the driving shaft inside the front cabin body 2 is arranged at the center line inside the docking seat 61; In this embodiment, the docking tube can not only realize the rotation transmission cooperation, but also realize the guidance of the subsequent reciprocating lateral movement. Through the limiting docking effect of the protrusion on the limiting ring and the guide groove inside the docking tube, the rotation and the subsequent reciprocating lateral movement process can be carried out simultaneously; The support of the support seat by the fixing rod and the cooperation between the rotating drum and the cam shaft can ensure that the cam shaft is in a stable installation and use state, and the ice-breaking drill bit can rotate synchronously with the transmission rod and move back and forth close to and away from the housing, and the bolts are fastened to connect the ice-breaking drill bit and the impact head. The impact head of this embodiment is made of titanium alloy, and its front end is in the shape of a bullet head, which can provide the maximum impact force when impacting the ice surface.

[0032] The scraper arranged on the outside of the ice-breaking drill bit of this embodiment is arranged in a serrated shape.

[0033] The auxiliary ice-breaking assembly of this embodiment can realize reciprocating telescopic auxiliary ice-breaking coordination during the tilting and floating process of the life-saving submersible, thereby improving the ice-breaking effect.

[0034] The convex shaft of the present embodiment is overall in a smooth round convex shape and can move smoothly in the convex shaft groove.

[0035] In this embodiment, through the cooperation between the rectangular guide groove and the protrusion on the outside of the limit ring, the subsequent lateral movement guiding effect can be stably realized. During the rotation of the drum, the circulating groove (cam shaft groove) opened on the outside is cooperated to transmit with the cam shaft to realize the simultaneous rotation and reciprocating lateral movement activities; the icebreaker drill bit is arranged in the shape of a cone head drill bit as a whole, and scrapers are installed on the upper and lower sides of the outer end of the icebreaker drill bit to ensure the high efficiency of the inclined floating icebreaking effect.

[0036] Specifically, when rescuing a wrecked submarine in an ice area, the buoyancy of the front cabin and the rear cabin is adjusted to achieve the tilting and buoyant movement of the life-saving submersible. During the tilting and buoyant process of the life-saving submersible, the ice-breaking device installed on the front cabin will be tilted to a position relative to the bottom of the ice layer, and cooperate with the driving device provided inside the front cabin to achieve the tilting and buoyant movement of the life-saving submersible. At the same time, with the operation of the driving device, the rotation of the rotating shaft is realized, and the docking tube will rotate synchronously, and cooperate with the limit device provided inside. The positioning ring is used to meet the synchronous rotation drive of the transmission rod. As the transmission rod rotates, the rotating drum installed on the outside of the transmission rod will rotate at the same time. The transmission rod can not only realize the rotation of the rotating drum, but also realize the rotation of the icebreaker drill bit, so that the icebreaker drill bit in an inclined floating state and rotating rapidly contacts the bottom of the thinner ice layer, so that the icebreaker drill bit can rotate and break the ice layer. At the same time, during the inclined floating process, the impact head installed on the icebreaker drill bit will be in advance connected with the ice layer to impact and break the ice layer. , ensuring the high efficiency of the subsequent icebreaking drill bit's rapid rotation and icebreaking effect, avoiding the occurrence of the problem of the icebreaking drill bit slipping during rotation and breaking ice. At the same time, the scrapers installed on the upper and lower sides of the icebreaking drill bit can rotate simultaneously with the icebreaking drill bit to scrape and break the ice layer through the external serrated end, accelerate the breaking of the ice layer, and make the lifesaving submersible quickly float to the surface. Secondly, during the rotation of the drum, the circulation groove opened on the outside of the drum can cooperate with the convex shaft to make the drum rotate and connect with the circulation groove opened on the outside of the drum. The convex shaft will be stabilized by the support seat and the fixed rod, so that the rotating drum in the rotating state can perform reciprocating and transverse movement at the same time. Therefore, the transmission rod will again perform the reciprocating and transverse movement of the transmission rod through the limiting docking effect of the limiting ring provided on the right and the rectangular groove (guide groove) opened inside the docking tube. Therefore, the icebreaking drill bit in the rotating icebreaking state will achieve the effects of rotating icebreaking and reciprocating impact icebreaking at the same time, so as to greatly improve the icebreaking effect on the front side of the life-saving submersible and accelerate the tilting and floating effect of the life-saving submersible.

[0037] The arrangement of the rotating drum, cam shaft, icebreaker drill bit and scraper, that is, when the rotating drum rotates with the transmission rod, the rotating drum cooperates with the docking effect of the circulating groove opened on the outside and the cam shaft, so that the rotating drum can synchronously realize the reciprocating lateral movement driving activity of the transmission rod during the rotation process, so that the transmission rod can not only realize the rotation impact driving of the icebreaker drill bit, but also enable the icebreaker drill bit to realize reciprocating impact icebreaking activity. At the same time, in cooperation with the scrapers arranged on both sides of the outer end, the icebreaking effect of the icebreaker drill bit is significantly enhanced.

[0038] In the present embodiment, the upper end of the limiting sleeve extends to the outside of the upper end of the shell, and maintains a stable supporting and guiding state through the limiting sleeve and the fixing plate, so that the subsequent telescopic impact icebreaking state is stable; the icebreaking surface outside the icebreaking cutting plate is set in a knife-edge shape, and the icebreaking cutting plate is made of titanium alloy as a whole, ensuring that the icebreaking cutting plate has a long life, wear resistance and corrosion resistance; in the present embodiment, the icebreaking drill bit, the impact head, the scraper and the icebreaking cutting plate work together to achieve a thin ice layer with a thickness of 0.5m-0.8m, thereby accelerating the tilting and floating rate of the life-saving submersible, reducing the probability of breaking ice by itself, and avoiding the occurrence of icebreaking damage to the cabin.

[0039] The icebreaker cutting plate as a whole will realize reciprocating extension and contraction icebreaking activities on the ice layer during the process of the life-saving submersible tilting and floating up, so as to deepen the icebreaking range and icebreaking effect, so that the cabin will not directly contact the ice layer during the process of tilting and floating up, which can avoid the collision and damage between the cabin and the ice layer, thereby significantly enhancing the icebreaking range and icebreaking effect, and improving the efficiency of icebreaking rescue; Secondly, when the ice-breaking cutting plate reciprocates and retracts to break ice, the damper installed inside the vertical tube can cooperate with the compression spring installed outside the damper to achieve the energy dissipation of the counter-impact force when the ice-breaking cutting plate impacts and breaks ice, avoid the impact of the counter-impact force on the internal structure, and ensure the stability of the reciprocating telescopic ice-breaking effect. The vertical tube can cooperate with the damper and compression spring installed inside to enable the ice-breaking cutting plate to reciprocate and retract to assist in ice-breaking, and achieve the energy dissipation of the counter-impact force, ensuring the stability of the overall structure. At the same time, under the limiting guidance of the limiting sleeve, the stability of the reciprocating telescopic ice-breaking direction and process can be guaranteed.

[0040] Specifically, the second guide groove on the moving shell of the auxiliary icebreaking assembly can move the internal connecting rod outward and inward through its own tilting direction. In this way, the icebreaking cutting plate will be indirectly transmitted to make the icebreaking cutting plate reciprocate and extend to break ice, so as to deepen the icebreaking range and efficiency, speed up the efficiency of the life-saving submersible's tilting and floating, and avoid the direct collision between the cabin and the ice layer during the tilting and floating process, thereby ensuring the overall safety of the life-saving submersible.
