The application discloses an electric vehicle charging protection device, which comprises a main body, a shielding part and a movable part, wherein the shielding part and the movable part are fixed on the main body; a controller, a button and a connecting port are arranged on the main body, the controller is connected with an external power supply and an electric device through the connecting port; a sleeve is arranged at the lower end of the shielding part, a connecting rod is arranged at the upper end of the main body, the shielding part is inserted into the sleeve through the connecting rod and is fixed at the upper end of the main body, so as to cover the button and the connecting port; the movable part comprises a support, a rotating block and a motor, the motor is fixed in the shielding part through the support, one end of the rotating block is connected with a driving end of the motor, the motor drives the rotating block to rotate and generates centrifugal force; the button and the motor are electrically connected with the controller. Through the arrangement of the shielding part and the movable part, the movable part drives the shielding part to move, the rotating block rotates and generates centrifugal force to make the accumulated snow above the shielding part fall off, the situation that the shielding part is deformed due to too much accumulated snow is avoided, and the safety and stability of the electric vehicle charging protection device are improved.

The application discloses a fan blade inspection device in the technical field of fan blade inspection, which comprises a fixing frame, a contraction mechanism arranged on the fixing frame, two moving mechanisms arranged in the fixing frame, an angle adjusting mechanism arranged in the fixing frame, a mounting block mounted on the angle adjusting mechanism, two multistage telescopic mechanisms arranged on the mounting block and in transmission connection, a connecting frame fixedly connected to the mounting block, an inspection table mounted on one end of the connecting frame, and two fixed components mounted on the bottom surface of the fixing frame.

The utility model provides a kind of liquid cooling pipeline with impurity removal function belongs to liquid cooling pipeline technical field, including first liquid cooling pipeline, drainage valve, filter, U-shaped pipeline, stop valve and second liquid cooling pipeline in turn communication, by stop valve can make impurity be retained in U-shaped pipeline, by drainage valve can be to the immersion liquid in U-shaped pipeline drainage to first liquid cooling pipeline, by filter can play the role of filtering impurity, by the impurity in U-shaped pipeline can reach the effect of removing impurity in immersion liquid.The utility model provides a kind of liquid cooling pipeline with impurity removal function, solve the technical problem that current used pipeline does not have the function of cleaning impurity, can threaten immersion liquid cooling system safety, with can remove impurity in immersion liquid, prevent to cause influence to immersion liquid cooling system safety.

The present application relates to a kind of typhoon can be released with platform's water isolation sleeve support system and its use method, wherein, typhoon can be released with platform's water isolation sleeve support system for supporting the water isolation sleeve of subsea well, subsea well is configured with deepwater self-elevating production platform around, the deepwater self-elevating production platform includes hull, the water isolation sleeve support system includes moving mechanism, bottom foundation and water isolation sleeve support frame, moving mechanism is set on the deck of hull;Bottom foundation is set to the sea bottom near deepwater self-elevating production platform;The bottom end of water isolation sleeve support frame is detachably connected on the bottom foundation, and the top end of water isolation sleeve support frame is connected with hull by moving mechanism.When typhoon is encountered, the moving mechanism releases water isolation sleeve support frame, realizes that water isolation sleeve support frame is quickly released from deepwater self-elevating production platform when typhoon is encountered;When deepwater self-elevating production platform moves or reinstallation, the moving mechanism will water isolation sleeve support frame be lifted to the deck of hull, realize that deepwater self-elevating production platform is moved together with water isolation sleeve support frame and reinstallation.
