Abstract: A fastening tool. In the fastening tool, a top part guiding matching portion engages a top part guiding portion in a sliding fit; a pressing part guiding matching portion engages a pressing part guiding portion in a sliding fit; a lever hinged to a base part; a transmission part engages a transmission part guiding slot in a sliding fit; the transmission part is driven to slide by the pressing part, and the lever is driven to rotate by the transmission part, then the top part is driven to slide out, due to a reaction force acting on the pressing part by the transmission part and the friction between the pressing part and the base part, the pressing part remains to be self-locked by friction, which can constrain the pressing part and the top part is locked.

Abstract: A hierarchical control method for an island power grid energy storage system for increasing new energy generation fluctuation is disclosed. The method includes implementing a rolling dispatch method based on an idea of model predictive control; comprehensively considering a response capability of the energy storage system to grid-wide economic dispatch instructions and life loss of energy storage lithium batteries, and constructing an objective function of an intraday control model of the energy storage system with economic optimization; and constructing, on a basis of satisfying the objective function of the intraday control model, a real-time control model of the energy storage system and solving the model, and determining charge and discharge plans of a lithium battery energy storage system and a supercapacitor energy storage system.

Abstract: An electronic apparatus includes: a first body including a first side and a second side arranged opposite to each other, and including a first input/output device disposed at the first side; a second body including a third side and a fourth side arranged opposite to each other, and including a second input/output device disposed at the third side; and a connector disposed at the first side and the fourth side. The second body rotates relative to the first body through the connector. During rotation of the second body, orientations of the first side and the third side substantially satisfy a same condition. The electronic apparatus includes a first attitude and a second attitude, which are switchable through the rotation of the second body. The second body does not block the first input/output device when the electronic apparatus is in the first attitude and the second attitude.

Abstract: An installation tool and installation method for fixing pins. In the mounting tool a cavity is provided in a tube body for accommodating a plurality of fixing pins. A first sliding groove and a second sliding groove are provided opposite each other and connected to the cavity. A first opening and a second opening are provided in two ends of the tube body. A pressing pin passes through the sliding grooves and is movably arranged on the tube body. The driving nut is adapted to driving the pressing pin to move towards the second opening.
