Description

Technical Field

[0001] The present invention relates to the technical field of underwater operation equipment and its peripheral accessories, in particular to a telescopic buoyancy regulating float. Background Art

[0002] For underwater tools requiring buoyancy adjustment, especially those requiring precise depth control, this has become a pressing issue. Traditionally, buoyancy adjustment involves changing the position of actuators through a series of mechanical transmissions, thereby adjusting the device's volume and thus controlling buoyancy. However, this transmission process requires mechanical self-locking to maintain the device's volume, resulting in low energy efficiency and wasteful energy. Furthermore, the technology for providing high-precision, reciprocating buoyancy adjustment in deep-sea environments is not yet mature. Furthermore, due to weight and volume constraints, the energy resources carried by the tools are extremely limited, making it difficult to control the reciprocating rise and fall of tools in the deep sea.

[0003] Chinese patent application number 201410338760.3 discloses a self-adjusting buoyancy float, including a variable-volume float, a hydraulic push rod, a depth detection device, and a hydraulic push rod control device. It uses a foldable body and lacks a strong mechanical structure to support the enormous pressure from the deep sea. This can easily damage the body during buoyancy adjustment, or the body cannot be extended due to excessive water pressure, thus failing to achieve buoyancy adjustment. Chinese patent application number 201610147200.9 discloses a buoyancy adjustment device. This technical solution has a complex system structure and the device design can achieve limited buoyancy adjustment, far from meeting the requirements of deep-sea buoyancy adjustment. The rotary drive used in this solution is reversible, and when the external pressure is too high, the push box end cover will move inward, failing to achieve the required buoyancy adjustment.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The present invention provides a telescopic buoyancy regulating float, comprising a float body 1, a telescopic device, a power device 2, a bladder, a detection device 3 and a control device. The telescopic device comprises a fixed frame 4, a movable frame 5 and a guide rail 6. The fixed frame 4 is connected to the guide rail 6, and the movable frame 5 is slidably arranged on the guide rail 6. The power device 2 is transmission-connected to the movable frame 5, and the power device 2 can drive the movable frame 5 to slide back and forth. The bladder is sleeved on the outside of the fixed frame 4 and the movable frame 5. The bladder is made of elastic material. The back and forth sliding of the movable frame 5 can cause the volume of the bladder to change. The detection device 3 can detect the buoyancy required by the underwater equipment. The detection device 3 and the power device 2 are both connected to the control device. The guide rail 6, the power device 2, the detection device 3 and the control device are all arranged on the float body 1. The relative sliding direction of the guide rail 6 and the movable frame 5 is parallel to the axial direction of the float body 1.

[0024] The telescopic buoyancy regulating float of the present invention is provided with a telescopic device, which adopts a fixed frame 4 and a movable frame 5. The movable frame 5 slides back and forth on the guide rail 6. By changing the distance between the fixed frame 4 and the movable frame 5, the purpose of changing the volume of the bladder is achieved. The change in the volume of the bladder will change the drainage volume of the underwater equipment, and thus change the buoyancy of the underwater equipment. When the detection device 3 detects that the buoyancy of the equipment needs to be increased, the control device transmits a signal to the power device 2, and the power device 2 drives the movable frame 5 to slide, increasing the distance between the movable frame 5 and the fixed frame 4, so that the volume of the bladder increases, and the drainage volume of the bladder increases, so that the buoyancy of the equipment as a whole increases, and the float body 1 drives the equipment to float; when the detection device 3 detects that the buoyancy of the equipment needs to be reduced, the control device transmits a signal to the power device 2, and the power device 2 drives the movable frame 5 to slide, reducing the distance between the movable frame 5 and the fixed frame 4, so that the volume of the bladder decreases, and the drainage volume of the bladder decreases, so that the buoyancy of the equipment as a whole decreases, and the float body 1 drives the equipment to sink, until the detection device 3 detects that the buoyancy reaches the requirement, the control device sends a stop signal to the power device 2, the power device 2 stops, the movable frame 5 stops sliding, and the buoyancy adjustment is completed.

[0025] More specifically, the fixed frame 4 is connected to one end of the guide rail 6 , and the number of the movable frames 5 is multiple, thereby ensuring the buoyancy adjustment range of the buoyancy adjustment float.

[0026] In addition, there are two guide rails 6, which are arranged on both sides of the float body 1. The fixed frame 4 and the movable frame 5 are both inverted U-shaped guide rails 6 with slide grooves. The two ends of the fixed frame 4 are respectively connected to the two guide rails 6, and the two ends of the movable frame 5 are respectively slidably arranged in the slide grooves. Both sides of the movable frame 5 are slidably connected to the guide rails 6, thereby improving the sliding uniformity of the movable frame 5.

[0027] In order to reduce the side friction between the movable frame 5 and the slide groove, the movable frame 5 is provided with a pulley, which is rotatably arranged in the slide groove, so that the movable frame 5 slides smoothly and reduces energy consumption.

[0028] Furthermore, the control device and the power device 2 are arranged on the bottom side wall of the buoy body 1, the telescopic device is arranged on the top of the control device and the power device 2, and the movable frame 5 is arranged between the fixed frame 4 and the power device 2. When operating in water, the control device and the power device 2 are located at the bottom of the buoy body 1, and the bladder is located at the top of the control device and the power device 2. The power device 2 and the control device can also play a role in adjusting the balance.

[0029] Furthermore, the power device 2 includes a motor and a drum 10. The drum 10 is connected to the motor transmission, and the motor can drive the drum 10 to rotate. The drum 10 is connected to the movable frame 5 through a pull rope 11. The rotation of the drum 10 can drive the movable frame 5 to move back and forth. The drum 10 pulls the movable frame 5 away from or close to the fixed frame 4 through the pull rope 11 to adjust the volume of the bladder. In other specific embodiments of the present invention, the motor can also drive the movable frame 5 to move through a sprocket chain or the like. The motor has a self-locking function, which can prevent the movable frame 5 from shaking after the buoyancy adjustment is completed, thereby ensuring the reliability of the buoyancy adjustment.

[0030] The telescopic buoyancy regulating float of the present invention is provided with a telescopic device. The telescopic device adopts a fixed frame 4 and a movable frame 5. The movable frame 5 slides back and forth on the guide rail 6 to achieve the purpose of changing the volume of the bladder. A support rod assembly 7 is set between the fixed frame 4 and the movable frame 5 to ensure the reliability of the telescopic device. The change in the volume of the bladder will change the drainage volume of the underwater equipment, and then change the buoyancy of the underwater equipment. The present invention changes the volume of the bladder through a mechanical telescopic device to achieve buoyancy adjustment. The structure is simple and easy to install. At the same time, a detection device 3 is provided. The detection device 3 can detect the buoyancy of the underwater equipment in real time, and then adjust the buoyancy according to actual conditions. The overall structure is compact, easy to use, and convenient to disassemble and maintain.
