Technology and life: starting with solar cars

Chapter 121

The design of the mecha is not too troublesome. Like solar cars, it adopts the method of mechanically lifting solar panels and solar concentrating glass panels.However, this mechanical lifting method can only be used for the home version of the mecha, and it is not suitable for those non-home version of the mecha.The main reason is that this kind of mechanical design is not very strong, and it is only suitable for high-intensity mecha activities. During high-intensity activities of the mecha, it is likely to damage the solar concentrating part of the mecha, especially the solar glass plate. Parts are even more easily damaged. After all, it is made of glass, and its hardness is acceptable, but its toughness is relatively poor, and it cannot be compared with those metal materials such as steel.

As mentioned earlier, the solar panel of the mecha is a solar panel of 1 meter 5X50 cm. Like the solar car, the material of the solar panel of 1 meter 5X50 cm is made of copper. It is used to strengthen the shape of the solar panel of the mecha, so as not to deform the solar panel, and at the same time transmit the solar energy to the wire, and this wire will continue to transmit the electric energy converted from the solar energy to the battery pack of the mech, like this The solar charging of the armor has been realized.The solar panel of the armor and the solar panel of the solar car are made of the same material. They are both made of monocrystalline silicon. The advantage of this material is that the utilization rate of solar light is higher. Moreover, the lifespan of this kind of monocrystalline silicon is longer than that of polycrystalline silicon. For the solar concentrating panels of mechs with a relatively small area, it must be monocrystalline silicon with a higher conversion rate of solar energy. Besides, monocrystalline silicon The price difference between polysilicon and polysilicon is not big, so it is definitely appropriate to choose monocrystalline silicon. The reason for choosing polysilicon is mainly because of the problem of solar energy collection, which can be calculated a little more.

The material of the solar panel is selected, and the conductive metal of the solar panel is also selected, then the design of the solar glass panel should be the next step.Like a solar car, you can freely design the number of convex lenses and the radius of curvature of the convex lens on a solar glass plate, as long as the focal length of the convex lens on the solar glass plate is kept within 40 cm, because if the solar glass plate If the focal length of the convex lens is too large, the distance between the solar glass plate and the back of the mecha will be too large, and the greater the distance between the solar glass plate and the back of the mecha, the mechanical part that concentrates the solar energy will be under the influence of gravity. It is more prone to failure under the action, so the height of the solar glass plate must be controlled, and the smaller the distance between the solar glass plate and the back of the mecha, the smaller.The smaller the distance between the solar glass plate and the mech, the better the stability of the mecha, the better the stability of the mecha, the less likely the mech is to break down, so the focal length selection of the convex lens of the solar glass plate In practice, it is better to be cautious, and it is better to choose as much as possible and make a convex lens with a relatively small focal length.Moreover, the design of the solar glass plate needs to be slightly improved. The solar glass plate removes the connecting part between the convex lenses, which looks good, but it does not need to be removed on the mecha, because it can increase the The stability of the mecha can also be said to increase the stability of the solar glass panel. There is a glass connection between the convex lenses. Ok let the solar glass panel withstand the force of the mech.The entire glass plate is designed to be the same size as the solar panel, or it is also possible to be 10 cm smaller than the length and width of the solar panel.For example, the solar panel of the armor is 1 meter 5X50 cm. At this time, we can design a solar glass plate of 1 meter 4X40 cm. The number of convex lenses on this glass plate can be carved according to the actual situation, for example, every 5 cm It is possible to make a convex lens or make a convex lens every 10 cm.If we use the method of multiplying every 10 cm by 10 cm to make a convex lens, then the length of 1 meter 4 can make 14 convex lenses of 10 cm, and the width of 40 cm can make 4 convex lenses. At this time, the entire solar glass panel 14 multiplied by 4 equals 56 convex lenses. The number of 56 convex lenses is very different from the number of convex lenses of solar cars, which naturally has a disadvantage in terms of lighting.In order to make up for the disadvantage of this area, the size of the convex lens can be changed. For example, if the size of the convex lens is set to 5 cm by 5 cm, the number of convex lenses will be doubled to 56 times. With 2, that is, the number of 112 convex lenses, there is no doubt that the collected solar light will be more at this time, which is more conducive to the collection of solar light.And there is no need to worry about problems with the solar panel due to too many solar concentrating points, because the glass on the solar panel and the metal material copper can withstand the high temperature of the solar concentrating point, so there is no need to worry about the solar panel being damaged. burnt out.

As for the solar mechanical part of the mecha, it is also like a solar car. It uses machinery to lift the mechanical part of the solar energy, but the difference is that the mechanical part is affected by gravity because the solar panel is perpendicular to the ground, so In the mechanical lifting part of the mecha, we must find ways to make the mechanical part of the mech stronger. For example, give the solar glass panels more positions to grab, so that as many solar glass panels as possible can be fixed to the mecha. When there are more connecting rods between the mechanical part of the mecha and the solar glass plate of the mecha, the solar concentrating part of the mecha will be more firm at this time.Still the same as the solar car, the solar glass plate and the mecha are connected together with connecting rods. The solar car is connected by two connecting rods to the car and the solar glass plate, and it is better to keep the mech in the mecha because of the need to overcome the gravity. Stability, so after all, let there be more connections between the mech and the solar panel. For example, put connecting rods around the solar glass panels, so that there are 4 connecting rods between the solar glass panels. The connection is more stable.At the same time, this part of the connecting rod can be changed from a hollow connecting rod to a solid connecting rod. The solid connecting rod has a better load-bearing effect than the hollow connecting rod.
