The invention discloses an oil-water separation device with a residue removal function, and belongs to the field of water treatment.The oil-water separation device is characterized in that a solid-liquid separation module is integrated on an oil-water separation module, a liquid outlet of the solid-liquid separation module is connected with a liquid inlet pipeline of the oil-water separation module, before oil-water separation, solid residues are removed firstly and prevented from entering the oil-water separation module, and then the oil-water separation module is separated; solid residues do not need to be manually removed or an oil outlet and a water outlet do not need to be continuously cleaned; a conical hopper box and a vacuum oil collection box are arranged on an oil-water separation box, an oil suction pipe is arranged in the vacuum oil collection box, the bottom end of the oil suction pipe extends into the conical hopper box, an oil outlet is formed in the side face of the vacuum oil collection box, a vacuum pipe is arranged at the top of the vacuum oil collection box, and the vacuum pipe is connected with a vacuum system. The floating oil is collected more thoroughly; the vacuum oil collecting tank is arranged at the top of the conical hopper box, negative pressure oil suction is adopted, a valve is arranged on a pipeline, oil outlet is more convenient, and automatic control can be achieved.

This utility model provides a suspended synchronous belt conveyor, which is U-shaped and includes a conveyor support, a drive motor, a drive pulley, a first guide pulley, a second guide pulley, a driven pulley, and a synchronous belt. The synchronous belt is sequentially wound around the drive pulley, the first guide pulley, the second guide pulley, and the driven pulley to form a closed transmission path. This suspended synchronous belt conveyor not only has high transmission efficiency and smooth operation but also achieves low-noise operation. By setting multiple sets of limiting components and a symmetrically distributed pulley and idler system, it effectively limits synchronous belt deviation, ensures uniform force distribution, reduces wear and sway, and extends the service life of the synchronous belt. Furthermore, the suspended synchronous belt conveyor also includes a hanging component, which facilitates the hanging and conveying of material bags. The overall structure is stable, easy to disassemble and maintain, and improves the practicality and reliability of the device.

This utility model discloses an unmanned security patrol vehicle, relating to the field of security equipment technology. It includes a vehicle body and a chassis, the chassis being welded from aluminum alloy. The vehicle body includes a driver's cab at the front and a rear trunk. The trunk contains a mounting bracket for storing emergency equipment, and an electric door is located on the outside of the trunk. Wheels and a power system are mounted on the chassis. Doors are located on both sides of the driver's cab, with alarm buttons above the doors. An alarm horn and a protective shell are located on the top of the vehicle body. An intelligent monitoring and control system is housed inside the protective shell, and a camera component is mounted on a bracket. This vehicle integrates four major functions: unmanned driving, anti-riot and explosion protection, fire assistance, and emergency alarm, solving the problem of limited functionality in existing patrol vehicles. It supports switching between unmanned automatic patrol and manual operation, improving patrol efficiency. In case of fire, the trunk can be remotely and automatically opened.

The utility model discloses a stator iron core and a motor, the stator iron core comprises an iron core body and first damping structures arranged on the peripheral surface of the iron core body, and a plurality of first damping structures are arranged along the axial direction of the iron core body at intervals. According to the technical scheme of the utility model, the technical problem that the existing stator core damping structure is poor in vibration and noise reduction effect is solved.
