According to the American Vaux website November 11, the bicycle path built by Dutch Solar Road Company is composed of rows of crystal silicon solar panels buried in concrete covered with translucent steel. glass". The 70-metre-long lane is open to the public on November 12. The solar road project was launched in 2009 and inspired by van Gogh's paintings "The Starry Night." A group of road construction and technical service providers led by the Dutch Applied Research Organization (TNO) studied the solar energy utilization potential of the Dutch roads and tested how much electricity the solar cycle road can produce in three years and calculated The security conditions in different weather, hope that the energy it generates can be used for street lights, homes and electric cars. Dutch solar driveway The bike lane costs about 3.7 million US dollars (about 2266 million yuan), and by 2016 the full-length 100-meter lane when completed, it will generate electricity will only be enough for 3 families. Some analysts believe that the "Sun Road" does not appear to be cost-effective. In addition, there are still some significant obstacles to this solar panel bike path. For example, solar panels installed under the road and bicycle road surfaces are covered with dust and snow, reducing power generation efficiency. Solar Roads Inc. hopes to slightly tilt the solar panels during installation and apply a non-stick coating to it to allow the rain to flush away the dust. Another problem is that these solar panels do not face the sun like photovoltaic panels on the roof, which means that they are expected to produce 30% less electricity than conventional solar panels. Working principle:
The working principle of the plate bending machine is to make the work roll move through the action of hydraulic pressure, mechanical force and other external forces, so that the plate can be bent or rolled into shape. According to the rotational movement and position changes of work rolls of different shapes, elliptical parts, arc parts, cylindrical parts and other parts can be processed.
The upper roller of the symmetrical plate rolling machine is in the symmetrical position of the center of the two lower rollers, and the hydraulic oil in the hydraulic cylinder acts on the piston to make vertical lifting motion, and the last stage gear of the main reducer drives the gears of the two lower rollers to mesh for rotational motion, so as to roll the plate. provide torque. The flat plastic metal plate of the plate rolling machine passes between the three work rolls (two lower rolls and one upper roll) of the plate rolling machine. With the help of the lower pressure of the upper roll and the rotation of the lower roll, the metal plate passes through multiple passes. Continuous bending (inner layer compression deformation, middle layer unchanged, outer layer tensile deformation), resulting in permanent plastic deformation, rolled into the required cylinder, cone or part of them. The disadvantage of this hydraulic three-roll plate bending machine is that the end of the plate needs to be pre-bent with other equipment. This plate rolling machine is suitable for large plate rolling machines with a thickness of more than 50mm. A row of fixed idlers is added to the lower part of the two lower rollers to shorten the span of the two lower rollers, thereby improving the accuracy of the rolled workpiece and the overall performance of the machine.

Due to the different fields of use, the types of plate rolling machines are also different. According to the number of rolls, it is divided into three-roller and four-roller. The three-roller is divided into a symmetrical three-roller plate rolling machine, a horizontal down three-roll plate rolling machine, an arc down type plate rolling machine, an upper roll universal three-roll plate rolling machine, and a hydraulic CNC plate rolling machine. From the transmission, it is divided into mechanical type and hydraulic type. In terms of the development of the plate rolling machine, the upper roll universal type is the most backward, the horizontal downward type is slightly advanced, and the arc downward type is the most advanced.
