Solar energy is an inexhaustible, clean, pollution-free and renewable green energy source. Photovoltaic power is considered to be the most important new energy in the twenty-first Century, with unparalleled advantages of other conventional energy such as cleanness, high security, the relative universality and sufficiency of energy, the long life and the maintenance free. The solar street lamps do not need to lay cables, do not have AC power supply, do not generate electricity, and use DC power supply and control. It has the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical and so on. It can be widely used in urban main roads, sub arterial roads, residential areas, factories, tourist attractions, parking lots and other places. The lamp pole structure of the product parts: steel lamp pole and bracket, the surface is sprayed with plastic, and the battery panel is connected with a special anti-theft stainless steel screw.

The solar street lamp system can guarantee normal work in rainy weather for more than 15 days. Its system is composed of LED light source (including drive), solar panel, battery (including battery insulation box), solar street lamp controller, street lamp lamp pole (including base) and auxiliary material and wire rod, and so on, which constitute [1].

Single crystal silicon or polysilicon solar cell components are generally selected for solar cell components; LED lamp head is generally used for high power LED light source; the controller is usually placed in the lamp pole with light control, time control, overcharge protection and reverse protection. More advanced controllers have four seasons to adjust the lighting time function and half power work. Able, intelligent charge and discharge function and so on; the battery is usually placed in the ground or there will be a special storage battery incubator, which can be used as valve controlled lead-acid battery, colloid battery, iron and aluminum battery or lithium battery. Solar lamps are fully automated without trenching and wiring, but the lampposts need to be installed on embedded parts (concrete bases).

1. high luminous efficiency, low power consumption, long service life and low working temperature.

2. safety and reliability.

3. the reaction speed is fast, the volume of the unit is small, and the environment is green.

4. in the same brightness, power consumption is 1/10 of the incandescent lamp, 1/3 of the fluorescent lamp, and 50 times the life of the incandescent lamp, 20 times the fluorescent lamp, and the fourth generation of lighting products after the incandescent lamp, the fluorescent lamp, and the gas discharge lamp.

The emergence of 5. single high-power ultra bright LED is possible in the LED application field to the high efficiency lighting source market, and will be one of the greatest inventions after Edison's invention of the incandescent lamp. [3]

Battery pack bracket

1) dip angle design

In order to allow solar cells to receive as much solar radiation as possible in a year, we need to choose the best tilt angle for solar cell components.

The discussion on the optimum tilt angle of solar cell components is based on different regions.

2) wind resistant design

In the solar street lamp system, a problem that needs to be attached great importance to is the design of wind resistance. The wind resistant design is mainly divided into two parts, one is the wind resistance design of the battery module bracket, the other is the wind resistance design of the lamp pole. The following two blocks are analyzed respectively.

Wind resistance design of solar cell component support

According to the technical parameters of the battery assembly manufacturers, the solar cell components can withstand an upwind pressure of 2700Pa. If the wind resistance coefficient is selected as 27m/s (equivalent to ten typhoons), according to the non viscous fluid mechanics, the wind pressure of the battery module is only 365Pa. Therefore, the components themselves can withstand the wind speed of 27m/s without damage. Therefore, the key to the design is the connection between the battery bracket and the lamp post.

In the design of the street lamp system, the connection between the battery component bracket and the lamp post is designed and connected by bolts.

The wind resistance design of the lamp pole of the road lamp

The parameters of the street lamp are as follows:

The dip angle of the battery board A = 16O height of the lamp pole = 5m

The width of the bottom weld of the lamppost is designed to be 4mm = the bottom diameter of the lamppost = 168mm

The face of the weld is the damage surface of the lamp pole. The resistance point W of the lamp pole is calculated from the point P to the action plate F of the lamp post.

PQ = [5000+ (168+6) /tan16o] * Sin16o = 1545mm=1.545m. Therefore, the moment of wind load on the failure surface of the lamp pole is M = F * 1.545.

According to the maximum allowable wind speed designed by 27m/s, the basic load of 2 x 30W dual head solar street lamp panel is 730N. Consider the safety factor of 1.3, F = 1.3 * 730 = 949N.

So, M = F * 1.545 = 949 * 1.545 = 1466N.m.

According to mathematical derivation, the resistance moment of circular failure surface is W = Pi x (3R2 Delta +3r 2+ 2+ 3).

In the upper form, R is the inner diameter of the ring and the width of the ring.

Failure surface resistance moment W = Pi x (3R2 Delta +3r Delta 2+ delta 3)

= * * * (3 x 842 x 4+3 x 84 x 42+43) = 88768mm3

=88.768 x 10-6 M3

The stress induced by the action moment of the wind load on the failure surface = M/W

= 1466/ (88.768 x 10-6) =16.5 * 106pa =16.5 Mpa<<215Mpa

Among them, 215 Mpa is the flexural strength of Q235 steel.

Therefore, the width of the designed weld meets the requirements. As long as the welding quality is guaranteed, the wind resistance of the lamp pole is no problem.

Controller

The main function of the solar charge and discharge controller is to protect the battery. The basic functions must be overcharge protection, over discharge protection, light control, time control, anti reverse connection, charging trickle protection, undervoltage protection, waterproof protection and so on. [1]

1) selection of devices

In the selection of devices, at present, there is a single chip computer and a comparator. There are many schemes, each has its own characteristics and advantages. It should be selected according to the needs of the customer group.

2) surface treatment

This series of products use the new technology of electrostatic coating, mainly with FP professional building materials paint. It can meet the customer's requirements for the harmony of color and environment on the surface of the product. At the same time, the product has high self cleaning, strong corrosion resistance and aging resistance. It is suitable for any climate environment. The processing technology is designed for hot dip zinc on the basis of coating, so that the product performance is greatly improved, to meet the most stringent requirements of AAMA2605.2005, other indicators have reached or exceeded the requirements of GB.

3) charge trickle protection

When the battery is charged by the Yijia solar panel, the battery will lose the water or lose control when it reaches the peak voltage. If the battery is charged, the battery can not be saturated if the charge is stopped. After charging to the peak voltage, the controller depressurizes 1V immediately and enters a trickle charge state. It ensures that the battery can be stable in full state and avoids the loss of water or out of control. It is similar to the cycle charge of the battery. It not only protects the battery from a high efficiency, but also raises the charge times and the service life of the battery. Longer.
