The utility model relates to electronic display screen heat preservation technical field, concretely relates to a kind of electronic display screen heat preservation device suitable for severe cold area outer wall.The heat preservation device includes heat preservation subassembly;Installation groove for installing the heat preservation subassembly is opened on the outer wall outer wall surface;The heat preservation subassembly includes heat preservation cavity, temperature controller and heater;The side of heat preservation cavity away from the outer wall is transparent wall surface;Electronic display screen, the temperature controller and the heater are arranged in the heat preservation cavity;The electronic display screen, the temperature controller and the heater are connected with power supply, and the temperature controller and the heater are connected.The utility model can solve the problem that electronic display screen is easily frozen in the prior art in severe cold area without heat preservation measure or heat preservation measure is not in place, or dull and slow reaction and display abnormality appear.

This invention discloses a lubricating oil metal shavings detection device, including an oil shavings separator connected to a sliding pipeline. A shavings sensor is installed on one side of the oil shavings separator, and the shavings sensor is connected to a shavings conditioner via a cable. The oil shavings separator can place metal shavings and lubricating oil in the lubricating oil below the shavings sensor and expel air from the lubricating oil from the top. The shavings sensor generates an induced voltage based on the metal shavings detected below and transmits the induced voltage signal to the shavings conditioner via the cable. The shavings conditioner can collect the number and size of the shavings based on the induced voltage transmitted by the shavings sensor and transmit this information to a host computer. In this invention, the shavings sensor uses a permanent magnet as the magnet, which can generate a stable magnetic field, has strong anti-interference ability against electromagnetic fields, and has more stable performance. The induced voltage in the induction coil is enhanced by increasing the lubricating oil flow rate. The entire device is a mechanical structure and is not affected by aircraft electromagnetic interference.
