The invention discloses a power management system for optimizing charging and discharging of a battery. The power management system comprises a voltage transformation main circuit, a current sampling circuit, a feedback loop module and a control logic module, the voltage transformation main circuit is connected to a voltage source and supplies power to a battery and a system at an output end through a built-in switch tube combined circuit structure; the current sampling circuit is used for receiving inductive current in the transformation main circuit and outputting a voltage signal; and the feedback loop module receives the voltage signal of the current sampling circuit and the sampling output voltage of the transformation main circuit, generates two paths of duty ratio signals, outputs the two paths of duty ratio signals to the control logic module, converts the two paths of duty ratio signals into four paths of driving signals, outputs the four paths of driving signals to switch tubes in the transformation main circuit, and completes driving and control of six switch tubes. The device can work in a buck-boost fast charging mode for fast charging and can also work in a dual-output working mode for independently supplying power to a battery and a system, the space area of an inductor under small-size equipment can be saved, and the service life of the battery can be prolonged.

The invention provides a preparation method of bismuth oxide modified straw biochar and application of the bismuth oxide modified straw biochar in estrogen contaminated soil remediation. The preparation method comprises the following steps: SS1, pretreatment of biochar; step SS2, preparation of biochar; and step SS3, grinding, screening, cleaning and drying the prepared biochar to obtain the bismuth oxide modified straw biochar. Straw particles and a bismuthic acid solution are mixed, surface modification and ultrasonic activation are carried out, then anaerobic pyrolysis of the biochar is carried out, the prepared bismuth oxide-biochar has the advantages that the infiltration capacity of bismuth oxide is larger, the loading capacity is higher, the combination of the bismuth oxide and the biochar is firmer, and the use durability is better.

This utility model relates to the field of milling machine processing technology and discloses a multi-angle rotating milling head, including a spindle connected to the milling machine to realize the milling work of the milling head. The spindle includes a columnar support cylinder with multiple positioning grooves evenly formed circumferentially inside the support cylinder. The support cylinder is integrally formed from high-strength aluminum alloy material with a tensile strength of not less than 500MPa and a yield strength of not less than 450MPa. A reinforcing mechanism is detachably assembled inside the spindle. The reinforcing mechanism includes a central connecting column, and multiple curved panels are embedded and fixedly arranged circumferentially on the outer surface of the connecting column. The multiple curved panels are distributed at a 120° angle to each other. This utility model uses high-quality materials and a reasonable structure, resulting in high strength, light weight, stable multi-angle operation, convenient disassembly and maintenance, reduced costs, and improved component recycling rate and equipment service life.
