Diving equipment with adjustable buoyancy

Abstract

The invention discloses diving equipment with adjustable buoyancy, and relates to the technical field of diving equipment. The diving equipment comprises a fixing block, wherein a binding device is mounted at the top of the fixing block; the bottom of the fixing block is fixedly connected with a gas storage pipe; the bottom of the gas storage pipe is communicated with a hose; the end, away from the gas storage pipe, of the hose communicates with a floating ball through a control pipe. The floating ball is filled with a weighting block, an exhaust device is installed in the control pipe, the outer side of the hose is sleeved with an air exhaust block, a driving groove is formed in one side of the inner wall of the air exhaust block, a gear is rotatably connected between the two sides of theinner wall of the driving groove, and a gear groove is formed in one side of the hose. According to the diving equipment with the adjustable buoyancy, the structure of a buoyancy adjusting device ofthe diving equipment can be simplified, the cost of the diving equipment is reduced, the functions of the buoyancy adjusting device are increased, the storage of breathable gas is increased while thebuoyancy of the equipment is reduced to achieve diving, and the diving time is prolonged.

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
