A deep-sea propulsion device with linear telescopic and full-rotation functions and its operation method

Abstract

A deep-sea propulsion device with linear telescopic and full-rotation functions and its operating method include a platform with a propulsion device installed inside via fasteners. The propulsion device can achieve the extension, retraction, and rotation of a deep-sea propeller. When retracted into place, the light outer shell of the propeller closes without affecting the linear shape of the entire platform. The propeller's extension and retraction functions are achieved by using a deep-sea linear telescopic oil cylinder with a displacement monitoring function, and the propeller's rotation function is achieved by using a deep-sea swing oil cylinder with a built-in angle sensor. The deep-sea linear telescopic oil cylinder with a displacement monitoring function is used to respectively achieve the propeller's telescopic locking and rotation locking functions, preventing the propeller from displacing again after extension and rotation, which could cause equipment failure. At the same time, the light outer shell of the propeller of the large deep-sea mobile platform can achieve synchronous telescopic and rotational functions with the propeller.

Description

Technical Field

[0001] The present invention relates to the technical field of recyclable and rotatable propellers used in the deep sea, and in particular to a deep sea propulsion device with linear telescopic and full-rotation functions and an operating method thereof. Background Art

[0002] Currently, the auxiliary or emergency propulsion devices commonly used on large deep-sea mobile platforms often have thrusters placed outside the platform's light hull or configured as slotted thrusters. When a large deep-sea mobile platform is sailing, the outboard thrusters and slotted holes significantly increase the resistance to navigation. To achieve a certain speed, the power of the main propulsion motor must be increased. Furthermore, large deep-sea mobile platforms often have fixed thrusters deployed to change the direction of thrust, achieving vector propulsion, resulting in an excessive number of thrusters. Both the increased resistance to navigation and the excessive number of thrusters reduce efficiency, increase economic costs, reduce economic benefits, and increase environmental pollution, resulting in numerous disadvantages. Summary of the Invention

[0003] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a deep-sea propulsion device with linear telescopic and full-rotation functions and an operating method, which can not only achieve 360° thrust steering, but also retract the thruster into the platform's light shell.

[0004] The technical solutions adopted in the present invention are as follows:

[0005] A deep-sea propulsion device with linear extension and full rotation functions includes a platform with a propulsion device installed inside the platform via fasteners. The propulsion device can realize the extension, retraction and rotation of the deep-sea propeller. When retracted into place, the light outer shell of the propeller is closed without affecting the linear shape of the entire platform.

[0006] The structure of the propulsion device is as follows: it includes a frame, a sliding cylinder body is installed inside the frame, a guide rod body is provided on the outside of the sliding cylinder body, a telescopic cylinder body with a deep-sea built-in displacement sensor is installed inside the sliding cylinder body, the output end of the telescopic cylinder body is fixed to the top of the frame, the bottom of the telescopic cylinder body is fixed to the lower fixed cylinder of the telescopic cylinder, the lower fixed cylinder of the telescopic cylinder is installed on the lower fixed cylinder of the telescopic cylinder, the swing cylinder body is supported and installed by a swing cylinder fixing frame, a lower bracket plate is fixed to the bottom of the frame, the lower fixed cylinder of the telescopic cylinder, the swing cylinder fixing frame, the outer shell of the swing cylinder body, the sliding bearing on the swing cylinder, and the swing cylinder sliding bearing are fixed together by bolts;

[0007] The rotating shafts of the swing cylinder body and the swing oil cylinder body are connected by bolts. At the same time, the swing cylinder body is connected to the propeller connecting flange and the deep-sea propeller by bolts. The rotation of the rotating shaft of the swing oil cylinder body can drive the rotation of the deep-sea propeller.

[0008] The sliding cylinder body, the swing cylinder sliding bearing and the bottom supporting plate are connected by bolts, and the swing cylinder body can rotate in the swing cylinder upper sliding bearing, the swing cylinder sliding bearing and the swing cylinder lower sliding bearing;

[0009] The telescopic locking oil cylinder is fixedly connected to the lower bracket plate by bolts. A through hole for the extension rod of the oil cylinder is opened on the sliding bearing of the sliding cylinder. A through hole is opened on the upper and lower ends of the sliding cylinder body respectively. This ensures that after the sliding cylinder body moves up and down into position, the extension rod of the telescopic locking oil cylinder of the deep-sea built-in displacement sensor can be inserted into the through holes on the upper and lower ends of the sliding cylinder body, ensuring the mechanical limit of the sliding cylinder body and ensuring that the thruster no longer moves up and down after being extended and retracted into position.

[0010] The bottom of the swing cylinder body is connected by fasteners, a sliding bearing under the swing cylinder and a bottom support plate. The bottom surface of the swing cylinder body is also equipped with a deep-sea propeller through a propeller connecting flange. The bottom of the deep-sea propeller is a light shell.

[0011] As a further improvement of the above technical solution:

[0012] The sliding cylinder body is a thin-walled cylinder, and a through hole is opened in the middle of the sliding cylinder body.

[0013] The top surface of the sliding cylinder body is provided with a flange and reinforcing ribs.

[0014] The cross section of the lower fixing tube of the telescopic oil cylinder is in a "J"-shaped structure.

[0015] The top of the guide rod body is fixed by a guide rod locking nut, and the bottom of the guide rod body is connected to the lower bracket plate through a guide rod sliding bearing.

[0016] The thruster connecting flange is in an I-shaped structure.

[0017] A method for operating a deep-sea propulsion device with linear telescopic and full-rotation functions includes the following operating procedures:

[0018] When a large deep-sea mobile platform is launched and needs to use a deep-sea propulsion device with linear telescopic and full-rotation functions, the output rods of the slewing locking cylinder and the telescopic locking cylinder are both in the longest state, and the deep-sea thruster is in the telescopic and slewing position locking state. First, the output shaft of the telescopic locking cylinder is retracted to the shortest, and the deep-sea thruster is in the telescopic unlocked state. At this time, the telescopic cylinder body begins to extend, and the slewing locking cylinder, the lower fixed cylinder of the telescopic cylinder, the swing cylinder body, the swing cylinder fixing frame, the sliding bearing on the swing cylinder, the swing cylinder sliding bearing, the swing cylinder body, the lower sliding bearing of the swing cylinder, the bottom support plate, the thruster connecting flange, the deep-sea thruster, and the light shell extend at the same time. When the output shaft of the telescopic cylinder body of the deep-sea built-in displacement sensor is extended When the cam is in the state of rotation and the cam is in the state of unlocking, the output shaft of the rotary locking oil cylinder of the deep-sea built-in angle sensor is retracted to the shortest position, and the output shaft of the rotary locking oil cylinder of the deep-sea built-in angle sensor is inserted into the upper through hole of the sliding cylinder body. The sliding cylinder body is mechanically limited, the telescopic state of the propeller is locked, and the light shell is also extended to the outermost side at the same time. When the propeller needs to rotate, the output shaft of the rotary locking oil cylinder is first retracted to the shortest position, the deep-sea propeller is in the state of rotation unlocking, and the output shaft of the swing cylinder body starts to rotate, driving the deep-sea propeller to rotate. When the output shaft of the swing cylinder body rotates into place, the output shaft of the rotary locking oil cylinder is extended to the longest position, and the output shaft of the rotary locking oil cylinder is inserted into a preset opening in the swing cylinder fixing frame of the deep-sea built-in angle sensor, and the propeller rotation is locked.

[0019] When the deep-sea large mobile platform does not need to be applied to the deep-sea propulsion device with linear telescopic full-rotation function, the output rods of the slewing locking cylinder and the telescopic locking cylinder are both in the longest state, and the deep-sea thruster is in the telescopic and slewing position locking state. First, the slewing locking cylinder output shaft is retracted to the shortest state, and the deep-sea thruster is in the unlocked state of rotation. The output shaft of the swing cylinder body starts to rotate in the opposite direction. When the output shaft of the swing cylinder body rotates into place, the slewing locking cylinder output shaft is extended to the longest, and the slewing locking cylinder output shaft is inserted into the original opening preset in the swing cylinder fixing frame, and the thruster rotation is locked; then the telescopic locking cylinder output shaft is retracted to the shortest state, and the deep-sea thruster is in the unlocked state of rotation. In the telescopic unlocking state, the telescopic cylinder body begins to retract, pulling back the rotary locking cylinder, the lower fixed cylinder of the telescopic cylinder, the swing cylinder body, the swing cylinder fixing frame, the sliding bearing on the swing cylinder, the swing cylinder sliding bearing, the swing cylinder body, the lower sliding bearing of the swing cylinder, the bottom support plate, the thruster connecting flange, the deep-sea thruster, and the light shell at the same time. When the output shaft of the telescopic cylinder body is retracted to the shortest, the output shaft of the telescopic locking cylinder is extended to the longest, and the output shaft of the telescopic locking cylinder is inserted into the lower through hole of the sliding cylinder body. The sliding cylinder body is mechanically limited, the thruster is locked in the telescopic state, and the light shell is retracted, thereby realizing the closure of the light shell of the large deep-sea mobile platform, and the hydrodynamics are not affected.

[0020] The beneficial effects of the present invention are as follows:

[0021] The present invention has a compact and reasonable structure and is easy to operate. It realizes the extension and retraction function of the propeller by adopting a deep-sea linear telescopic oil cylinder with a displacement monitoring function, realizes the rotation function of the propeller by adopting a deep-sea swing oil cylinder with a built-in angle sensor, and realizes the telescopic locking and rotation locking functions of the propeller by adopting a deep-sea linear telescopic oil cylinder with a displacement monitoring function, respectively, to prevent the propeller from being displaced again after being extended and rotated into place, thereby causing equipment failure. At the same time, the light outer shell on the outside of the propeller of the deep-sea large mobile platform can realize the function of synchronous extension and rotation with the propeller. When the propeller is extended, it will open with the light outer shell to perform power position control. When the propeller is retracted into place, the light outer shell on the outside of the propeller will close, which will not affect the linear shape of the entire platform. Therefore, the resistance of the deep-sea large mobile platform will not increase, and the purpose of reducing environmental pollution and increasing economic benefits can be achieved.

A method for operating a deep-sea propulsion device with linear, telescopic, and fully rotating functions as claimed in claim 1, characterized in that: The following operating procedures are included: When a large deep-sea mobile platform (b) is launched into the water and needs to be applied to a deep-sea propulsion device (a) with a linear telescopic and full-rotation function, the output rods of the slewing locking oil cylinder (6) and the telescopic locking oil cylinder (21) are both in the longest state, and the deep-sea propeller (12) is in the telescopic and slewing position locking state. First, the output shaft of the telescopic locking oil cylinder (21) is retracted to the shortest, and the deep-sea propeller (12) is in the telescopic unlocking state. At this time, the telescopic oil cylinder body (2) begins to extend, and the slewing locking oil cylinder (6), the lower fixed cylinder of the telescopic oil cylinder (7), the swing oil cylinder body (8), the swing oil cylinder fixing frame (14), the upper sliding bearing of the swing cylinder (15), the swing cylinder sliding bearing (16), the swing cylinder body (17), the lower sliding bearing of the swing cylinder (18), the bottom support plate (19), the propeller connecting flange (20), the deep-sea propeller (12), and the light shell (13) are extended at the same time. When the deep-sea built-in displacement sensor After the output shaft of the telescopic oil cylinder body (2) is extended to the longest, the output shaft of the telescopic locking oil cylinder (21) of the deep-sea built-in displacement sensor is extended to the longest, and the output shaft of the telescopic locking oil cylinder (21) of the deep-sea built-in displacement sensor is inserted into the upper through hole of the sliding cylinder body (5). The sliding cylinder body (5) is mechanically limited, the propeller is locked in the telescopic state, and the light shell (13) is also extended to the outermost side at the same time; when the propeller needs to rotate, the output shaft of the rotary locking oil cylinder (6) is first retracted to the shortest, the deep-sea propeller (12) is in the rotation unlocking state, and the output shaft of the swing cylinder body (17) starts to rotate, driving the deep-sea propeller (12) to rotate. When the output shaft of the swing cylinder body (17) rotates into place, the output shaft of the rotary locking oil cylinder (6) is extended to the longest, and the output shaft of the rotary locking oil cylinder (6) is inserted into a preset opening in the swing oil cylinder fixing frame (14) of the deep-sea built-in angle sensor, and the propeller rotation is locked; When the deep-sea large mobile platform (b) does not need to be applied to the deep-sea propulsion device (a) with linear telescopic full-rotation function, the output rods of the slewing locking oil cylinder (6) and the telescopic locking oil cylinder (21) are both in the longest state, and the deep-sea propeller (12) is in the telescopic and slewing position locking state. First, the output shaft of the slewing locking oil cylinder (6) is retracted to the shortest state, and the deep-sea propeller (12) is in the unlocked state of rotation. The output shaft of the swing cylinder body (17) starts to rotate in the reverse direction. When the output shaft of the swing cylinder body (17) rotates into place, the output shaft of the slewing locking oil cylinder (6) is extended to the longest, and the output shaft of the slewing locking oil cylinder (6) is inserted into the original opening preset in the swing cylinder fixing frame (14), and the propeller rotation is locked; then the output shaft of the telescopic locking oil cylinder (21) is retracted to the shortest state, and the deep-sea propeller (12) is in the telescopic unlocked state. The telescopic oil cylinder body The body (2) starts to retract, and the rotary locking oil cylinder (6), the lower fixed cylinder of the telescopic oil cylinder (7), the swing oil cylinder body (8), the swing oil cylinder fixed frame (14), the upper sliding bearing of the swing cylinder (15), the swing cylinder sliding bearing (16), the swing cylinder body (17), the lower sliding bearing of the swing cylinder (18), the bottom supporting plate (19), the propeller connecting flange (20), the deep-sea propeller (12), and the light shell (13) are pulled back at the same time. When the output shaft of the telescopic oil cylinder body (2) is retracted to the shortest, the output shaft of the telescopic locking oil cylinder (21) is extended to the longest, and the output shaft of the telescopic locking oil cylinder (21) is inserted into the lower through hole of the sliding cylinder body (5). The sliding cylinder body (5) is mechanically limited, the propeller is locked in the telescopic state, and the light shell (13) is retracted, so that the light shell (13) of the deep-sea large mobile platform (b) is closed, and the hydrodynamic force is not affected.
