This invention belongs to the field of flow battery energy storage technology, and relates to a negative electrode electrolyte for alkaline all-iron flow batteries and its preparation method. The negative electrode electrolyte is prepared from iron salts, a complexing agent, a promoting component, an alkaline component, an auxiliary electrolyte, and water. The total iron concentration is 0.1–2.0 mol / L, the molar ratio of the complexing agent to the iron salt is 1.5–4, the molar ratio of the promoting component to Fe is 0.05–1.0, the alkaline component concentration is 2.0–6.0 mol / L, and the auxiliary electrolyte concentration is 0–2.0 mol / L. The negative electrode electrolyte of this invention for alkaline all-iron flow batteries has a high total iron concentration, which not only avoids the precipitation of elemental iron during charging and discharging, but also effectively prevents the formation of ferric hydroxide precipitate, improves the stability of iron ions, and greatly extends the cycle life of the negative electrode electrolyte. It can be widely used in aqueous alkaline all-iron flow batteries.

This invention discloses a multifunctional pen integrating laser ranging and illumination, comprising a pen body and a clip. The clip has a protrusion, and the pen body is equipped with a display module and an interactive input component. The core of this invention lies in its unique spatial layout. The laser emitting module of the laser ranging component is cleverly positioned within the protrusion of the clip, while the laser receiving part is located in the center of the pen body. Simultaneously, a pen tip is coaxially mounted inside the pen body, with the pen tip pointing in the opposite direction to the ranging and transmitting / receiving direction. Furthermore, a Hall effect knob control component is fitted externally to the pen body for convenient interaction, and an internal linkage power supply structure automatically activates the circuit and illuminates the light-emitting unit when the pen is rotated. This invention perfectly integrates the ranging optical path into a compact pen body, achieving a highly efficient working experience where measurement is performed at one end and illumination and recording are performed at the other without interference.

This utility model discloses a deck vertical lifting structure for a remote-controlled lawnmower, including a body, a deck suspension plate, an electric push rod, a transmission assembly, and a reset assembly. The body is a frame structure with fixed plates fixedly connected to the upper part of both sides of the rear. The electric push rod is fixedly connected to the front end of the fixed plates. The output end of the electric push rod is fixedly connected to the transmission assembly below via a U-shaped seat. The lower part of the transmission assembly is fixedly connected to the edge of the deck suspension plate. The middle part of the reset assembly is fixedly connected to the inner side of the body of the machine, and the bottom part is fixedly connected to the upper surface of the deck suspension plate. The electric push rod converts the horizontal driving force into a vertical force through the transmission assembly and transmits it to the deck suspension plate, realizing the lowering or raising of the deck suspension plate. The reset assembly enables the deck suspension plate to quickly reset when it needs to be raised after lowering. This application has the following advantages: improved mowing efficiency, improved mowing quality, enhanced terrain adaptability, reduced operating difficulty, and reduced structural space.
