The ship trajectory monitoring method and system based on Beidou positioning of the present invention belong to the field of radio positioning technology. The buoy component is applied to trajectory monitoring and navigation route planning. Before the ship sails, the obstacles faced by the ship during navigation or the ocean conditions during the ship's navigation can be monitored in advance according to the set buoy component, and the navigation route of the ship can be planned in advance. When the navigation route needs to be changed, the original coordinate position of the buoy component can be used as the center of the circle and a certain distance can be used as the radius to drive the collection buoy to rotate around the ocean to detect the sea conditions or obstacle information on the ocean surface. After comparison, the best navigation position is selected, and the buoy component is changed from the original coordinates to the existing best navigation position coordinates, thereby re-planning the navigation route of the ship, and the navigation route of the ship can be planned quickly, accurately and more safely.

The utility model discloses a reinforcing device for confined water layer shield equipment, which belongs to the technical field of shield construction and comprises a supporting main body and a reinforcing main body. The supporting body extends in the first linear direction. The reinforcing main body is arranged in the supporting main body, the reinforcing main body comprises a reinforcing wall body and an abutting piece, the reinforcing wall body and the supporting main body are coaxially arranged, a containing space is defined by the reinforcing wall body, the shield tunneling equipment can move in the containing space in the first linear direction, and a mounting space is formed between the reinforcing wall body and the supporting main body; the abutting piece is arranged in the mounting space, one end of the abutting piece is connected with the outer wall of the reinforcing wall, the other end of the abutting piece is connected with the supporting body, and the abutting piece can drive the reinforcing wall to move in the direction close to the shield tunneling equipment. Through cooperation of the supporting body, the reinforcing wall body and the abutting piece, the posture of the reinforcing wall body is adjusted through the abutting piece, tight connection between the shield tunneling equipment and an external structure is ensured, and the water stopping effect and stability of the device are enhanced.

This invention discloses a compact protein purification device, relating to the field of protein purification equipment technology. It includes a ring frame, a support column mounted below the ring frame, and a base connected to the support column; a moving mechanism mounted on the base, the moving mechanism including a third lifting rod mounted on the base, a rotating ring rotatably connected to the outside of the support column, and a disc connected to the rotating ring via an adjusting member. The third lifting rod drives the rotating ring, the adjusting member, and the disc to move vertically. It also includes a mixing cylinder and a processing mechanism mounted on the ring frame; a second annular groove formed inside the ring frame; a support frame slidably connected to the support column; a receiving cylinder located below the mixing cylinder; and a gravity chromatography column connected to the receiving cylinder via a connecting pipe. This compact protein purification device, by incorporating the processing mechanism and the moving mechanism, achieves the goal of improving the efficiency of the equipment.
