The utility model belongs to the technical field of oil cylinders, and particularly relates to a mechanical locking oil cylinder which comprises a cylinder body, a locking cavity is formed in the cylinder body, a locking mechanism is installed in the locking cavity, the locking mechanism comprises a matching round block, a matching rod is fixedly installed on the matching round block, a steel ball is installed on the matching rod in a sliding mode, and the steel ball is arranged on the matching rod. When hydraulic oil is introduced into the oil inlet pipe, the steel ball is propped open so as to enter the left side of the sliding cavity to prop out the piston rod, and when hydraulic oil is stopped from being introduced from the oil inlet pipe, under the action of the spring, the piston rod is locked by the locking piston. The steel ball is pressed against the second L-shaped cavity, so that the function of locking the piston rod is achieved, after hydraulic oil is introduced from the oil return pipe, the hydraulic oil presses the locking piston out of the matching cavity, so that the steel ball is pressed away, so that locking of the piston rod is unlocked, the design structure is simple, and the automatic locking function is achieved.

The application discloses a marine low-speed diesel engine propulsion system safety monitoring instrument, and relates to the technical field of ship safety monitoring. The lower side of the outer wall of the base is provided with a positioning block one, the side of the diesel engine body close to the base is provided with a groove one, the groove one is matched with the positioning block one, the lower side of the outer wall of the positioning block one is provided with a mounting groove, the inside of the mounting groove is provided with a pressure sensor, the middle part of the outer wall of the base is provided with a mounting hole, the inside of the mounting hole is provided with a pre-tightening bolt, the inner wall of the base is provided with a shearing groove in the radial direction, and the inside of the shearing groove is provided with a buffer block in interference. The positioning block one, the groove one, the pre-tightening bolt, the pressure sensor, the acceleration sensor and the temperature sensor are installed, the function of stable information collection is realized, the base installation pre-tightening force can be maintained in the vibration working condition through the self-locking of the positioning block one and the groove one, and the equipment information collection accuracy and stability are improved.
