Disposable ocean profile parameter measuring instrument

The invention relates to a disposable ocean profile parameter measuring instrument, and belongs to the field of ocean profile parameter measurement, wherein the disposable ocean profile parameter measuring instrument comprises a counter weight, a buoyancy compartment, a detection mechanism and a controller; the counter weight is connected with the buoyancy compartment through a connecting mechanism, and the controller is arranged in the buoyancy compartment; the controller is in communication connection with the connection mechanism and the detection mechanism; and the controller is used for controlling the connecting mechanism to separate the counter weight from the buoyancy compartment through mechanical transmission under the condition that a detector descends to a set depth, and the controller is also used for controlling the detection mechanism to detect ocean profile parameters. After the detector sinks to a target position, the buoyancy compartment of the detector can be quickly separated from the coun
