Diving equipment with adjustable buoyancy

Abstract

The invention discloses a diving equipment with adjustable buoyancy, which relates to the technical field of diving equipment. The bottom of the air pipe is connected with a hose, the end of the hose away from the air storage pipe is connected with a floating ball through a control pipe, the inside of the floating ball is filled with a weight block, and an exhaust device is installed in the inside of the control pipe. The outer side of the hose is sleeved with an air extraction block, a driving groove is opened on one side of the inner wall of the air extraction block, a gear is rotatably connected between the two sides of the inner wall of the driving groove, and one side of the hose is provided with a gear groove. The buoyancy-adjustable diving equipment can simplify the structure of the buoyancy adjustment device of the diving equipment, reduce the cost of the diving equipment, increase the function of the buoyancy adjustment device, and increase the storage of breathable gas while reducing the buoyancy of the equipment to achieve diving. Increase dive time.

Description

technical field [0001] The invention relates to the technical field of diving equipment, in particular to diving equipment with adjustable buoyancy. Background technique [0002] The original intention of diving is to carry out underwater surveys, salvage, repairs and underwater engineering operations, with or without carrying professional tools to enter the activities below the surface of the water, and then diving has gradually developed into an activity that focuses on underwater activities. Content, so as to achieve the purpose of physical exercise, leisure and entertainment leisure sports, widely loved by the public. In order to achieve a deeper dive, it is usually necessary to carry tools to increase the gravity of the diver.

Problems solved by technology

[0003] Chinese invention CN106477011A discloses a buoyancy adjustment and pressure compensation system and method for submersibles, including a shell, which is filled with a certain pressure of gas, and more than two elastic airbags are installed on the shell, and the elastic airbags are filled with Gas at a certain pressure, and through the perforated protective shell covering it, is in contact with the inside and outside of the housing. The pressure of the gas inflated in each elastic airbag is different, and the gas pressure in the housing is lower than that in the elastic airbag. The gas pressure; the shell is equipped with an elastic water bag, a two-way seawater hydraulic pump and a seawater solenoid valve. When diving, the control system controls the seawater solenoid valve to energize and connect the one-way waterway from the external water environment to the elastic water bag. When the gas pressure is greater than or equal to the pressure of the external water environment, the control system controls the motor to rotate and drive the two-way seawater hydraulic pump to press the water in the external water environment into the elastic water bag. The volume of the shell remains unchanged and the mass increases to achieve diving, but the structure is complicated and the cost is high. The function is single and can only reduce the buoyancy to achieve the purpose of diving. The volume occupied by the gas inside the device cannot be converted into breathable gas storage after the reduction, and the capacity of breathable gas cannot be increased while reducing the buoyancy to achieve the dive. , increasing the dive time
