Vertical real-time control device of non-tide water depth measuring measurement rod of GPS (Global Positioning System)

The utility model discloses a vertical real-time control device of a non-tide water depth measuring measurement rod of a GPS (Global Positioning System). The vertical real-time control device comprises a fixing rack, a turbulent flow cover, a rocker, an attitude and position sensor and a mini-type control computer, wherein the upper end of the rocker is connected with a transverse electric cylinder and a vertical electric cylinder; the transverse electric cylinder and the vertical electric cylinder are arranged in a right angle; one end of each of the transverse electric cylinder and the vertical electric cylinder is connected with the upper end of the rocker through one spherical hinge, and the other ends of the transverse electric cylinder and the vertical electric cylinder are connected with the fixing rack through one spherical hinge; the lower end part of the rocker is connected with a support plate through a Hooke hinge; the support plate is fixedly connected with the internal lower part of the turbulent flow cover; a measuring rod is mounted inside the rocker in a penetrating manner; a GPS positioning block is mounted at the upper end of the measuring rod, and a sonar emitter is mounted at the lower end of the measuring rod; the mini-type control computer collects an attitude signal of the measuring rod, generates a control signal, and transmits the control signal to the electric cylinders; and the electric cylinders draw the measuring rod to a vertical position through retraction. With the adoption of the vertical real-time control device provided by the utility model, the measuring rod keeps a vertical state all along, so that the sounding precision is improved.
