The utility model discloses a centering and leveling device of an engineering surveying and mapping instrument, which relates to the technical field of engineering surveying and mapping and comprises a base, a lifting component, a mounting rod and a leveling seat. The lifting assembly comprises a plurality of lifting structures which are arranged on the base at intervals; the mounting rod extends in the vertical direction, the bottom end of the mounting rod is supported on the top of the base, and the angle of the mounting rod can be adjusted relative to the base; a mounting position is formed on the leveling seat, the mounting rod is mounted at the mounting position, a spirit level for detecting the levelness of the leveling seat is arranged on the leveling seat, the plurality of lifting structures are arranged around the mounting position, a plurality of supporting positions are formed at the bottom of the leveling seat, and each supporting position is supported at the top of the corresponding lifting structure. According to the centering and leveling device of the engineering surveying and mapping instrument, leveling is easy and convenient, the occupied space is small, and the engineering surveying and mapping instrument can be leveled in a narrow area.

The present application relates to the technical field of water gate cleaning, and particularly relates to a gate slot underwater cleaning device and a use method. The gate slot underwater cleaning device comprises a frame, the frame comprises a bottom plate and vertical supports arranged at four corners of the bottom plate; one climbing structure is arranged on each vertical support, each climbing structure is provided with a climbing frame, the climbing frame and the vertical support are fixedly connected through a connecting rod, the climbing frame is suitable for being electromagnetically attracted to the inner wall of the gate slot; a horizontal sensor is arranged on the bottom plate; a controller is in communication connection with the horizontal sensor and the climbing frame; in a water entry state, the horizontal sensor senses the levelness of the bottom plate and transmits the levelness to the controller in real time, the controller controls the climbing frame to move up and down along the gate slot, so that the bottom plate is kept in a horizontal state. The present application solves the problem that the automatic cleaning device is affected by multiple factors such as water flow after entering the water, and the automatic cleaning device is inclined when moving along the gate slot, thereby affecting the dirt cleaning effect.
