Abstract

The utility model relates to a self-generating street lamp capable of generating power by using pressure difference. The self-generating street lamp is characterized in that a plurality of wind driven generators are arranged in a vertical column of the street lamp, wherein an arc wind cap is arranged on the upper part of the vertical column; a storage battery and an electric connection circuit are arranged in the vertical column; the vertical column is made of a transparent material; and a salt layer is arranged on a part, which faces the north, of the vertical column. A using method is that when air flow flows through the arc wind cap, the flow speed is increased, and the pressure intensity is reduced; the air flow with the high pressure intensity flows from bottom to top, so that strong upflow is formed; furthermore, the black salt layer in the vertical column absorbs heat of the sunshine, so that heated air moves upwards, and another strong upflow is formed; the strong upflow pushes the wind driven generators in the vertical column to rotate and generate power; and the power is used by the street lamp for lighting. The street lamp has the beneficial effects that a power generation facility is arranged in the vertical column of the street lamp, so that the maintenance rate is low, and the using cost is relatively low. The black salt layer is used as a solar power generation facility, so that the street lamp has the advantages of low cost and long service life when being compared with a solar battery panel.

The specific embodiment

The utility model is to be provided with many wind-driven generator 2(to see Fig. 2 in street lamp column 1).On street lamp column top, one cambered surface blast cap 3 is set.Battery 4 is set in the street lamp column and control circuit 11(material object does not draw).Annexation wherein is referring to the circuit block diagram of Fig. 4, and described control circuit 11 comprises rectification circuit 21, mu balanced circuit 22, relay 24 and photosensitive detecting unit 26; Many wind-driven generators 2, rectification circuit 21, mu balanced circuit 22, battery 4, relay 24 and street lamp illuminating part 7 orders are electrically connected to; Relay 24 also is electrically connected to a photosensitive detecting unit 26.Like this, the device of generating is all in street lamp column 1 inside, to prevent loss rapidly under the wind and weather state.Street lamp column 1 bottom is provided with a plurality of air inlets 5.When natural airflow flows through arc blast cap 3, flow velocity can be accelerated, and according to bernoulli principle, the pressure on street lamp column 1 top reduces, and the air flow direction top that street lamp column 1 bottom pressure is high, form one uprush, from blast cap, goes out, and flows to extraneous.Air-flow faster (wind is larger in other words), ascending air intensity is larger.This uprush is to promote first strand of power source that wind-driven generator rotates.According to chimney effect, street lamp column 1 is higher, and this ascending air intensity is also larger.

Promote the air-flow that also has another burst of rising that wind-driven generator rotates: street lamp column 1 of the present utility model is transparent material, can see through sunray.Air in sunshine heating street lamp column, according to the principle of hot air rising, promote wind-driven generator and rotate generating.In order there is no at night the solar time, still have the thermal current of rising in the street lamp column, in the part of being exposed to the north of street lamp column 1, the semicircular cylinder 8(that is provided with the transparent material making is shown in Fig. 3), semicircular cylinder 8 is isometric with street lamp column 1.Be provided with salt deposit 9(salt and there is good thermal storage performance between semicircular cylinder 8 and street lamp column 1, in night, can emit heat, the air in heating street lamp column 1); In salt deposit 9, the surface of salt is made as and absorbs the good black of sunlight heat, and this black can be realized by the method for coating black pigment.This black is conducive to absorb the heat of sunshine, the air in heating street lamp column.If the heat accumulation deficiency of salt deposit, thermal current can weaken or disappear.But the above-mentioned uprush formed by pressure difference still exists, first strand of power source still exists, and still can promote wind-driven generator and rotate generating.

Wind-driven generator 2 electricity, through rectification circuit 21 rectifications, after mu balanced circuit 22 voltage stabilizings, are stored in battery 4; Light sensor in photosensitive detecting unit 26 detects ambient brightness when not enough, and starting relay 24 is connected being electrically connected between batteries 4 and street lamp illuminating part 7, is street lamp illuminating part 7 power supply light emittings; Light sensor in photosensitive detecting unit 26 detects ambient brightness when sufficient, and starting relay 24 disconnects being electrically connected between batteries 4 and street lamp illuminating part 7, and battery 4 stops powering to street lamp illuminating part 7, and street lamp illuminating part 7 extinguishes.Rectification circuit 21, mu balanced circuit 22, battery 4, relay 24 and street lamp illuminating part 7 and photosensitive detecting unit 26, all can adopt known components and parts and known circuit.

In sum, the method that the utility model is used is achieved in that

Cross arc blast cap 3 when air flow stream, flow velocity can be accelerated, and according to bernoulli principle, the pressure on street lamp column 1 top reduces, and the air flow direction top that street lamp column 1 bottom pressure is high, form one uprush, flows to extraneous; On the other hand, the salt deposit 9 of the black in street lamp column 1 absorbs the heat of sunshine, and heat is stored in salt deposit 9, the heat of the sunshine absorbed has heated the air in street lamp column 1, heated air upwards, forms another strand of uprush, flows to extraneous; Like this, above-mentioned two strands of uprush, promote many wind-driven generators 2 in street lamp column 1 and rotate generating.Many rectification circuit 21 rectifications of wind-driven generator 2 electricity in control circuit 11, after mu balanced circuit 22 voltage stabilizings, be stored in battery 4; Light sensor in photosensitive detecting unit 26 detects ambient brightness when not enough, and starting relay 24 is connected being electrically connected between batteries 4 and street lamp illuminating part 7, is street lamp illuminating part 7 power supply light emittings; When the light sensor in photosensitive detecting unit 26 detects the ambient brightness abundance, starting relay 24 disconnects being electrically connected between batteries 4 and street lamp illuminating part 7, battery 4 stops to 7 power supplies of street lamp illuminating part, and street lamp illuminating part 7 extinguishes, and battery 4 continues store electrical energy.

So go round and begin again, street lamp illuminating part 7 relies on the natural energy resources electricity, and in night illumination, extinguish daytime.
