Description

利用压强差发电的自发电式路灯及其使用方法
技术领域
本发明属于照明设备，尤其是涉及一种利用自然能源发电的路灯。
背景技术
   为了节约能源，保护环境，目前已经出现了几种利用太阳能和风能提供电力的路灯。太阳能发电主要是利用太阳能电池板，风能发电主要是利用路灯顶部安装的风力发电机。上述发电装置均暴露在外，日晒雨淋，使用寿命较低，维修几率高，导致使用成本上升。
发明内容
本发明的目的是针对上述自然能源发电的路灯，提出一种维修几率较低的自然能源发电的路灯：将发电装置设置在能挡风遮雨的路灯立柱内部，利用路灯立柱内外的压强差发电，为路灯提供稳定的电源。
本发明的具体技术装置是这样实现的：包括路灯立柱、路灯发光件，其特征是，
在路灯立柱上部设置一弧面风帽，路灯立柱内设置多只风力发电机和一蓄电池及控制电路，路灯立柱下部设有多个进风口；控制电路分别与多只风力发电机、蓄电池及路灯发光件连接；
路灯立柱为透明材料，路灯立柱的朝北的部分，设有透明材料制作的半圆筒，半圆筒与路灯立柱等长，两者之间设有盐层；盐层中盐的表面设为黑色；
所述控制电路包括整流电路、稳压电路、继电器和光敏检测单元；所述多只风力发电机、整流电路、稳压电路、蓄电池、继电器和路灯发光件顺序电连接，所述继电器还与光敏检测单元电连接；
上述装置的使用方法：
气流流过弧形风帽，流速加快，压强降低，路灯立柱下部压强高的气流流向上部，形成一股强上升气流，流向外界；另一方面，路灯立柱内的黑色的盐层吸收太阳光的热量，并将热量储存在盐层中，吸收的太阳光的热量加热了路灯立柱内的空气，被加热的空气向上，形成另一股强上升气流，流向外界；这样，上述两股强上升气流，推动路灯立柱中多只风力发电机转动发电，多只风力发电机发的电通过控制电路储存在蓄电池内；当控制电路检测到环境亮度不足时，接通蓄电池与路灯发光件之间的电连接，蓄电池供电于路灯发光件照明；当控制电路检测到环境亮度充足时，断开蓄电池与路灯发光件之间的电连接，蓄电池停止向路灯发光件供电，路灯发光件熄灭，蓄电池继续储存电能；
如此周而复始，路灯发光件依靠自然能源发的电，在夜间照明，白天熄灭。
本发明与现有的路灯相比有如下有益效果：
一、由于利用自然能源的发电设施均在路灯立柱内部，维修的几率较低，从而使用成本较低。
二、本发明利用黑色盐层作为太阳能发电的设施，与太阳能电池板相比较，具有成本低，寿命长的优点。
附图说明
下面结合图和实施例对本发明进一步说明。
图1是本发明的总体示意图。
图2是图1的剖视图。
图3是图2中的路灯立柱1的横截面示意图。
图4是本发明的电路框图。
具体实施方式
本发明是在路灯立柱1内设置了多只风力发电机2（见图2）。在路灯立柱上部设置一弧面风帽3。路灯立柱中设置蓄电池4和控制电路11（实物未画出）。其中的连接关系参见图4的电路框图，所述控制电路11包括整流电路21、稳压电路22、继电器24和光敏检测单元26；多只风力发电机2、整流电路21、稳压电路22、蓄电池4、继电器24和路灯发光件7顺序电连接；继电器24还与一光敏检测单元26电连接。这样，发电的装置均在路灯立柱1内部，以防止在风吹雨淋状态下迅速的损耗。路灯立柱1下部设有多个进风口5。当自然气流流过弧形风帽3，流速会加快，根据伯努利原理，路灯立柱1上部的压强降低，路灯立柱1下部压强高的气流流向上部，形成一股强上升气流，从风帽下出去，流向外界。气流越快（或者说风越大），上升气流强度越大。该强上升气流是推动风力发电机转动的第一股动力源。根据烟筒效应，路灯立柱1越高，该上升气流强度也越大。
推动风力发电机转动的还有另一股上升的气流：本发明的路灯立柱1为透明材料，可以透过太阳光线。太阳光加热路灯立柱中的空气，根据热空气上升的原理，推动风力发电机转动发电。为了在晚上没有太阳时，路灯立柱内仍有上升的热气流，在路灯立柱1的朝北的部分，设有透明材料制作的半圆筒8（见图3），半圆筒8与路灯立柱1等长。在半圆筒8与路灯立柱1之间设有盐层9（盐具有良好的储热性能，在晚间能够放出热量，加热路灯立柱1内的空气）；盐层9中盐的表面设为吸收太阳光热良好的黑色，该黑色可以用涂黑色颜料的方法加以实现。该黑色有利于吸收太阳光的热量，加热路灯立柱内的空气。如果盐层的储热不足，热气流会减弱或消失。但前面提到的由压强差形成的强上升气流依然存在，即第一股动力源依然存在，仍旧会推动风力发电机转动发电。
风力发电机2发的电经整流电路21整流，经稳压电路22稳压后，储存在蓄电池4内；当光敏检测单元26中的光敏传感器检测到环境亮度不足时，启动继电器24接通蓄电池4与路灯发光件7之间的电连接，为路灯发光件7供电发光；当光敏检测单元26中的光敏传感器检测到环境亮度充足时，启动继电器24断开蓄电池4与路灯发光件7之间的电连接，蓄电池4停止向路灯发光件7供电，路灯发光件7熄灭。整流电路21、稳压电路22、蓄电池4、继电器24和路灯发光件7和光敏检测单元26，均可采用公知的元器件和公知的电路。
综上所述，本发明使用的方法是这样实现的：
当气流流过弧形风帽3，流速会加快，根据伯努利原理，路灯立柱1上部的压强降低，路灯立柱1下部压强高的气流流向上部，形成一股强上升气流，流向外界；另一方面，路灯立柱1内的黑色的盐层9吸收太阳光的热量，并将热量储存在盐层9中，吸收的太阳光的热量加热了路灯立柱1内的空气，被加热的空气向上，形成另一股强上升气流，流向外界；这样，上述两股强上升气流，推动路灯立柱1中多只风力发电机2转动发电。多只风力发电机2发的电经控制电路11中的整流电路21整流，经稳压电路22稳压后，储存在蓄电池4内；当光敏检测单元26中的光敏传感器检测到环境亮度不足时，启动继电器24接通蓄电池4与路灯发光件7之间的电连接，为路灯发光件7供电发光；当光敏检测单元26中的光敏传感器检测到环境亮度充足时，启动继电器24断开蓄电池4与路灯发光件7之间的电连接，蓄电池4停止向路灯发光件7供电，路灯发光件7熄灭，蓄电池4继续储存电能。
如此周而复始，路灯发光件7依靠自然能源发的电，在夜间照明，白天熄灭。
