Embodiment Construction

[0049] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] Such as figure 1 As shown, an airbag type underwater depth-fixing levitation device in this embodiment includes an actuator, a depth sensor 19 , a control system 20 and a power supply 21 .

[0051] The actuator includes an exhaust device, an air bag 11, an air bag connecting accessory and an inflating device.

[0052] The exhaust device is used to discharge the gas in the airbag 11 to the external water area, so as to reduce the volume of the airbag 11, thereby reducing the buoyancy of the system. The exhaust device is a motor-driven air valve, which consists of a valve cover 1, a valve body 2, a valve core spring 3, a valve core 4, a rubber pad 5, a motor 6, a reduction gear set 7, a gear 8, and a rack 9 , Rack spring 10 forms.

[0053] The valve cover 1 is connected to the opening of the air bag 11, and the lower end of the valve cover 1 ha...

Abstract

The invention relates to a gas bag type underwater depth-control suspension system which is suitable for a carrying platform for underwater operation, and belongs to the field of water suspension appliances. The gas bag type underwater depth-control suspension system comprises an actuator, a depth transducer, a control system and a power supply. The actuator comprises an exhaust device, a gas bag, a gas bag connection accessory and an inflation device, wherein the exhaust device is used for exhausting gas in the gas bag and reducing the buoyancy of a suspension system body, the gas bag is used for providing the buoyancy for the system body, the gas bag connection accessory is used for connecting the gas bag with a shell of the suspension system body, and the inflation device is used for inflating the gas bag and increasing the buoyancy of the suspension system body. The depth transducer is used for measuring the underwater depth of the suspension system in real time and transmitting a depth signal to the control system. The control system is used for receiving and processing the depth signal and then appropriately controlling the actuator to move according to a preset control rule. According to the gas bag type underwater depth-control suspension system, gas is used as buoyancy adjusting media and stored in high-pressure gas cylinders in a compression mode, the gas bag is in a folded state before being inflated, therefore, the suspension system is compact in whole structure, small in size, large in specific gravity, and capable of loading large weight.

Description

technical field [0001] The invention relates to an airbag type underwater depth-fixed suspension system, which is suitable for a carrying platform for underwater operations and belongs to the field of underwater suspension equipment. Background technique [0002] In the process of developing marine resources, it is often required that the operating equipment can be suspended in a predetermined depth range underwater, which requires that the equipment should have the function of underwater fixed-depth suspension. Underwater fixed-depth levitation technology has been widely used in both civilian and military fields, such as submarines, underwater robots, and fixed-depth mines. Existing levitation technologies are generally divided into two methods: lift adjustment and buoyancy adjustment. Lift regulation means that the suspension relies on the lift generated by the blades when the propeller rotates to control the depth change. In order to maintain the suspension depth, the p...
