Description

Technical Field

[0001] The present invention relates to the technical field of sofa production, and in particular to an emergency buoy releasing device and method for a Jiaolong manned submersible. Background Art

[0002] Submarines, also known as submarines, submarines, and submersible boats, are ships that can operate underwater. Submarines are of various types and shapes, ranging from small civilian submersible detectors that are fully automatic or operated by one or two people and have an operating time of several hours, to Russian Typhoon-class nuclear submarines that can carry hundreds of people and dive continuously for 3-6 months. During the use of the Jiaolong submersible used in China, an emergency buoy release device will be installed on its outside, and emergency buoys will be used to call for help in an emergency.

[0003] During use of the existing emergency buoy releasing device for the Jiaolong manned submersible, in order to ensure that the position of the emergency buoy rising to the sea surface is in a corresponding state with the submersible below, the buoy needs to be pulled by a rope. The rope is wrapped around the outside of the winding roller. The buoy's own buoyancy is in a constant state. During the process of floating up, if it suddenly accelerates, there must be other power pushing it on the outside. This power pushing is the acceleration of the flowing seawater caused by the swimming of marine organisms. The emergency buoy is more likely to be pushed laterally. At this time, the rope unwinding speed increases, which causes the emergency buoy to slowly deviate to the predetermined position, reducing its rescue effect and causing the release device to lack use value. Summary of the invention

[0004] The present invention discloses an emergency buoy releasing device for a Jiaolong manned submersible, which aims to solve the problem that in order to ensure that the position of the emergency buoy rising to the sea surface is in a corresponding state with the submersible below, the buoy needs to be pulled by a rope, the rope is wound around the outside of a winding roller, the buoy's own buoyancy is in a constant state, and if it suddenly accelerates during its floating process, there must be other driving forces on its outside, which are caused by the movement of marine organisms to accelerate the flow of seawater, and the emergency buoy is more likely to be driven lateral, and the rope unwinding speed increases at this time, which causes the emergency buoy to slowly deviate toward a predetermined position, reducing its rescue effect.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] By providing a speed regulating component, during the process of releasing the buoy body, when the buoy body is floating up, if the flow of marine life causes the flow of water outside the buoy body to accelerate, the buoy body will passively move in the direction deviating from the predetermined track, which will increase the pay-out speed of the rope. When the rope movement speed increases, the rotation speed of the contact swivel will increase, which will increase the contact time between the contact swivel and the friction rod in the same period of time, greatly increasing the friction resistance of the contact swivel. The contact swivel and the rope are in a state of squeeze contact. By limiting the rotation speed of the contact swivel, the pay-out speed of the rope is limited, ensuring that the accelerated seawater cannot cause impact on the buoy body in other directions, ensuring that the buoy body can reach the original track. The compression spring rod here is always in a compressed state, ensuring that the friction resistance between the friction rod and the contact swivel will only increase, not decrease.

[0011] By providing a manual release component, when releasing the buoy body, the personnel inside the submersible manually pull the pull rope to cause the extrusion spring rod to be continuously compressed. The misaligned teeth on the extrusion plate cannot limit the rope, and the buoy body slowly rises under the action of its own buoyancy. This method is a manual operation, which avoids power damage to the submersible in the deep sea due to malfunction, and makes it impossible to release the buoy body through electric equipment, thereby ensuring that the release device can be applied to various emergency situations.

[0012] In a preferred solution, one side of one of the end plates is fixedly connected with a plurality of fixing rods, and the other ends of the plurality of fixing rods are fixedly connected with the same fixing plate, a driving assembly is provided on the side of the fixing plate facing the end plate, the driving assembly comprises a motor box, the motor box is fixedly connected to one side of the fixing plate, a driving motor is fixedly connected to the inner side of the motor box, and the output shaft of the driving motor is fixedly connected to a docking shaft via a coupling, a docking frame is fixedly connected to the outer side of the docking shaft, hydraulic cylinders are distributed in a ring shape on the inner side of the docking frame, the output end of each hydraulic cylinder is fixedly connected with an embedded column, an embedded groove is provided in a ring shape on the outer side of the rotating shaft, and the number and position of the embedded columns and embedded grooves are matched.

[0013] By providing a driving component, when the personnel inside the submersible are rescued at the marking point of the buoy body and the rope is reeled in, the hydraulic cylinder is adjusted to drive the embedding column to be inserted into each embedding groove, and then the driving motor is started. The driving motor drives the docking shaft to rotate, and then drives the reeling roller to reel in the rope, completing the collection of the buoy body. This is convenient and efficient, and further improves the use value of the releasing device.

[0014] A method for using an emergency buoy release device for a Jiaolong manned submersible is applied to the above-mentioned emergency buoy release device for a Jiaolong manned submersible. The method for using comprises the following steps:

By limiting the rotation speed of the contact swivel, the pay-off speed of the rope is limited, ensuring that the accelerated seawater cannot cause impacts on the buoy body in other directions, and ensuring that the buoy body can reach the original track.

[0019] When releasing the buoy body, the personnel inside the submersible manually pull the pull rope to cause the extrusion spring rod to be continuously compressed. The misaligned teeth on the extrusion plate cannot limit the rope, and the buoy body slowly rises under the action of its own buoyancy.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] The present invention discloses an emergency buoy releasing device for a Jiaolong manned submersible, which is mainly used to ensure that the position of the emergency buoy rising to the sea surface is in a corresponding state with the submersible below. The buoy needs to be pulled by a rope, and the rope is wound around the outside of the winding roller. The buoy's own buoyancy is in a constant state. During its floating process, if it suddenly accelerates, there must be other driving forces on its outside. The driving force is the acceleration of the flowing seawater caused by the swimming of marine organisms. The emergency buoy is more likely to be driven laterally. At this time, the rope unwinding speed increases, which causes the emergency buoy to slowly deviate toward a predetermined position, reducing its rescue effect.

[0031] Reference Figure 1-Figure 8 A buoy release device for an emergency buoy of a Jiaolong manned submersible includes a mounting plate 1, a sliding sleeve 18 and a buoy body 5. A connecting rod 4 is fixedly connected to the outside of the sliding sleeve 18, and a connecting plate 17 is fixedly connected to the side of the connecting rod 4 close to the top. A speed adjustment component 13 is provided on the connecting plate 17. The speed adjustment component 13 includes two side plates 1302, and the two side plates 1302 are fixedly connected to the outside of the connecting plate 17. Two shaft plates 1306 are fixedly connected to the opposite sides of the two side plates 1302, and the opposite sides of the two shaft plates 1306 on the same side plate 1302 are connected to the same rotating shaft 1304 through bearings. The outsides of the two rotating shafts 1304 are fixedly connected to contact swivels 1301. The two connecting The two sides of the contact rotating ring 1301 at proximal positions are fixedly connected with limiting arc blocks 1303, and the opposite sides of the two side plates 1302 are fixedly connected with two abutment blocks 1305, each abutment block 1305 is fixedly connected with an outer cylinder 1307 on the side facing the contact rotating ring 1301, each outer cylinder 1307 is slidably connected with an inner sliding rod 1310, each inner sliding rod 1310 is fixedly connected with a compression spring rod 1309 at one end located on the inner side of the outer cylinder 1307, and the other end of the compression spring rod 1309 is fixedly connected to the inner side of the outer cylinder 1307, and each inner sliding rod 1310 is fixedly connected with a friction long rod 1308 at one end close to the contact rotating ring 1301, and the friction long rod 1308 is in contact with the outer side of the contact rotating ring 1301.

[0032] It should be noted that during the release of the buoy body 5, when the buoy body 5 is floating up, if the flow of marine life causes the flow of water outside the buoy body 5 to accelerate, the buoy body 5 will passively move in the direction deviating from the predetermined track, which will cause the pay-off speed of the rope 9 to increase. When the moving speed of the rope 9 increases, the rotation speed of the contact swivel 1301 increases, which will cause the contact time of the contact swivel 1301 with the friction rod 1308 to increase in the same time, so that the friction resistance of the contact swivel 1301 is greatly increased, and the contact swivel 1301 and the rope 9 are in a state of extruded contact. By limiting the rotation speed of the contact swivel 1301, the pay-off speed of the rope 9 is limited, ensuring that the accelerated seawater cannot cause impact on the buoy body 5 in other directions, ensuring that the buoy body 5 can reach the original track. The compression spring rod 1309 here is always in a compressed state, ensuring that the friction resistance between the friction rod 1308 and the contact swivel 1301 will only increase, not decrease.

[0036] It should be noted that when releasing the buoy body 5, the personnel inside the submersible manually pull the pull rope 1503, so that the extrusion spring rod 1508 is continuously compressed, and the offset teeth 1506 on the extrusion plate 1505 cannot limit the rope 9. The buoy body 5 slowly rises under the action of its own buoyancy. This method is a manual operation, which avoids power damage to the submersible in the deep sea due to malfunction, and makes it impossible to release the buoy body 5 through electric equipment, thereby ensuring that the release device can be applied to various emergency situations.

[0039] S1: When releasing the buoy body 5, the personnel inside the submersible manually pull the pulling rope 1503, so that the squeezing spring rod 1508 is continuously compressed, and the misaligned teeth 1506 on the squeezing plate 1505 cannot limit the rope 9, and the buoy body 5 slowly rises under the action of its own buoyancy;

[0040] S2: During the ascent of the buoy body 5, if the buoy body 5 passively moves in a direction deviating from the predetermined track, the contact time of the contact swivel 1301 and the friction rod 1308 increases within the same period of time, so that the friction resistance of the contact swivel 1301 is greatly increased, and the contact swivel 1301 and the rope 9 are in a state of squeeze contact.

A method for using the emergency buoy release device of the Jiaolong manned submersible, applied to the emergency buoy release device of the Jiaolong manned submersible as claimed in claim 9, characterized in that: The method of use comprises the following steps: S1: When releasing the buoy body (5), a person inside the submersible manually pulls the pulling rope (1503), so that the squeezing spring rod (1508) is continuously compressed, and the misaligned teeth (1506) on the squeezing plate (1505) cannot limit the rope (9), and the buoy body (5) slowly rises under the action of its own buoyancy; S2: During the ascent of the buoy body (5), if the buoy body (5) is passively moved in a direction deviating from the predetermined track, the contact time of the contact swivel (1301) and the friction rod (1308) increases within the same period of time, so that the friction resistance of the contact swivel (1301) is greatly increased, and the contact swivel (1301) and the rope (9) are in a state of squeeze contact. By limiting the rotation speed of the contact swivel (1301), it is ensured that the buoy body (5) floats to a predetermined position; S3: When the personnel inside the submersible are rescued at the marking point of the buoy body (5), the rope (9) is reeled in by adjusting the hydraulic cylinder (1602) to drive the embedding column (1603) to fit into each embedding groove (1607), and then starting the drive motor (1605). The drive motor (1605) drives the docking shaft (1606) to rotate, and then drives the reeling roller (11) to reel in the rope (9), thereby completing the collection of the buoy body (5).
