The pipe, the long spray bar and the multi-nozzle are characterized in that the working platform behind the water tank of the car body is attached to the lifting frame to connect the long spray bar and the multi-nozzle. After the electric water pump is pumped and pressurized from the water pipe of the water tank, it is connected through the "three links". The hose is divided into two channels (also single) into the long spray nozzle and multi-nozzle sprinkler. The movable lifting frame can be used to upgrade the long spray bar and multiple nozzles. The end of the long spray bar is equipped with “fire”.

The nozzle, that is, the water supply, is divided into short-range, medium-range and remote sprinkler irrigation. With water supply in place, wide irrigation area, high efficiency, good efficiency, high efficiency and low cost. Can also be used as a high-rise fire truck.

The development of automobile intelligent lighting device Liu Shenquan Qiao Jiangang Lv Yuliang (North China Institute of Technology Branch Taiyuan 030008) The signal is converted into a voltage signal after amplification, comparison and delay processing, and the single-chip microcomputer is used to judge the delay signal to control the relay switch, thereby achieving the running light. Automatic control and conversion to ensure safe driving.

Study on Calculation Method of Bearing Capacity of Permanent Magnetic Suspension Bearing in Ultra-High Speed ​​Centrifuge Guo Kexi Pan Cunyun (Changsha University of Electric Power, Changsha 410077) (National University of Defense Technology) Inductive strength, studied the calculation method of bearing capacity of permanent magnet bearing, and provided valuable value for design of permanent magnet bearing system The theoretical basis.

Research on a new type of intelligent locknut Li Junliang Du Yanliang Shen Yingming Sun Baochen (Institute of Large-scale Structural Health Diagnosis and Control, Shijiazhuang Railway Institute, Shijiazhuang 0520043) The nut of the seed is that it does not change the original structure of the mother, only changes the material, and uses the iron-based shape memory. The shape memory characteristics of the alloy material itself make the threaded connection firm and not loose. The feasibility of this nut was verified by experiments.
