2results about How to "Low noise operation" patented technology

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.
