Activated sludge oxygen production conveying device

The utility model provides an activated sludge oxygen production conveying device, which relates to the technical field of oxygen transportation and mainly structurally comprises a base and clamping plates, a mounting seat is arranged on the base, the clamping plates are mounted on two sides of the mounting seat, a ratchet wheel and a pawl for controlling the clamping plates to open and close are arranged on the base, the ratchet wheel and the pawl are pivoted on the base, and the ratchet wheel is meshed with the pawl. The clamping plate and the ratchet wheel rotate coaxially, the ratchet wheel is prevented from retreating through clamping of the pawl stressed by the positioning column and the spring, when the oxygen bottle is placed in the mounting base, the clamping plate can automatically gather and clamp the oxygen bottle, when the oxygen bottle needs to be taken down, only the cam needs to be rotated to loosen the pawl, and convenience and safety in the carrying process of workers are greatly improved. 本
