所述伸缩支架3与电机4连接，该伸缩支架3通过电机4控制在打开状态与收拢状态之间切换。所述电机4的关闭可为手动关闭。当然所述伸缩支架3也可以通过手动进行关闭。所述雨棚5固定在伸缩支架3上。当伸缩支架3打开时，雨棚4随之打开。当伸缩支架3收拢时，雨棚5随之收拢。所述雨棚5用于遮挡雨。通常情况下，当所述雨水监控仪2检测到雨水为酸雨时，发送启动电机4的打开信号，促使电机4工作将伸缩支架3打开，从而使得将雨棚5打开，避免酸雨与雨棚5下的土壤及植物接触，从而实现保护植物及土壤的效果。所述雨,5由柔性的塑料制成。所以雨棚5可以随着伸缩支架3的打开与收缩而同步打开、收缩。
所述雨水采集器1开设有一容纳腔10，该容纳腔10用于收集雨水。所述雨水监控仪2的部分穿插在该容纳腔10内。具体地，至少可将雨水监控仪2检测的雨水部件穿插在容纳腔10内。当需要检测是否有酸雨的情况下，该雨水采集器1放置于户外。由于雨水采集器1是用于采集自然落下的雨水，因此容纳腔10朝向天空的方向是开口的，以便雨水落入容纳腔10内。通过容纳腔10对雨水进行收集，以便雨水监控仪2更好地与雨水接触，提高检测效率。
参照图3，所述雨水监控仪2包括第一采集模块21、第二采集模块22、计算模块23及控制模块24。所述第一采集模块21与雨水接触后产生电动势，并将该电动势发送至计算模块23。第一采集模块21包括测量电极与参比电极，所述测量电极是对氢离子具有选择性的电极。因此当将该第一采集模块21插入待测雨水中时，可根据雨水酸碱度而产生相应的电动势。所述计算模块23及控制模块24可组合为单片机的一部分模块。所述第二采集模块22可为温度传感器及折光仪。

第一壳体2121及第二壳体2131均由玻璃制成。所述第一检测溶液2122与第二检测溶液2132均为浓度为3mol/L左右的氯化钾溶液，其中第一检测溶液2122占第一壳体2121内部空间的1\9-1\51左右；第二检测溶液2132占第二壳体2131内部空间的1\9-1\51左右。所述第一电极导线2123及第二电极导线2133可为氯化银。
所述第二采集模块22用于检测被监控雨水的温度值和折射率，并将该温度值和折射率发送至计算模块23。所述计算模块23根据接收的电动势、温度值以及折射率计算雨水的PH值，并发送至控制模块24。所述控制模块24根据PH值的大小生成控制信号，并将控制信号发送至电机4。所述第二采集模块22可为折射仪又称折光仪。
所述计算模块23可为计算器，该计算模块23采用如下公式(1)(2)计算雨水的PH值：
Figure PCTCN2016092447-appb-000003
Figure PCTCN2016092447-appb-000004
其中：E为电动势；E0可为小于或等于E常数；E2与E1分别为第一采集模块21内第一检测溶液2122及第二检测溶液2132的电位，PH2与PH1为第一采集模块21内第一检测溶液2122及第二检测溶液2132的PH值；T为雨水的温度，R为雨水的折射率；lnα(H+)为雨水的PH值。通过在雨水监控仪2中设置第二采集模块22来采集雨水的温度值与折射率可有效的提高雨水监控仪2检测的精确度。lgR表示以10为底的对数，lnα(H+)表示以e为底的对数。

所述控制模块24包括接收模块241、判断模块242、信号生成模块243及发送模块244。所述接收模块241用于接收计算模块23发出的PH值。所述判断模块242用于判断接收模块241接收的PH值是否小于5.6，若是则说明该雨水为酸雨，需要将雨棚打开，否则可以不用打开雨棚。所述信号生成模块243用于根据所述判断模块判断242的结果为是时，生成打开电机4的打开信号。所述发送模块244用于将所述打开电机4的打开信号发送至电机4。
所述电机4在接收到所述打开电机4的打开信号之后启动，驱动所述伸缩支架3打开，进而将雨棚5打开。当雨棚5下具有植物时，可通过打开状态的雨棚5对雨水进行阻隔，防止雨水与植物接触。
所述伸缩支架3包括滑轨31、滑块32、第一伸缩组件33、第二伸缩组件34及横向杆35。所述滑轨31上开设有滑槽310。所述滑块32安装在滑槽310内，该滑块32与电机4通过链条连接。由于雨棚5为具有防水效果的柔性塑料制成，可通过两个伸缩组件来支撑雨棚5，避免雨水过多的堆积在雨棚5上，从而可有效提高雨棚5的耐用性。可通过电机5驱动滑块32在滑槽310滑动。所述横向杆35与滑轨31平行设置。所述第一伸缩组件33与滑块32及横向杆35均连接，该第一伸缩组件33根据滑块32的状态在伸长状态与收缩状态之间切换。以所述滑块32为两个时对第一伸缩组件33的伸缩状态进行描述， 当两个滑块32相互靠近至相互接触的状态下，该第一伸缩组件33呈完全打开状态，此时横向杆35与滑轨31之间的直线距离最大；当两个所述滑块32之间的直线距离逐渐增大时，该第一伸缩组件33实现逐渐收拢，此时横向杆35与滑轨31之间的距离逐渐缩短。所述第二伸缩组件34与所述滑轨31及横向杆35固接。
所述第一伸缩组件33包括至少一组伸缩杆组；各伸缩杆组包括两个交叉设置的第一伸缩杆331，并在交叉的位置设置有转轴332，该转轴332同时穿过两个第一伸缩杆331，使得两个第一伸缩杆331能以该转轴332进行旋转。当两个第一伸缩杆331在以转轴332为中心转动时，使得两个第一伸缩杆331之间的夹角发生变化，实现第一伸缩组件33伸长与缩短。结合图1，所述伸缩杆组为两组，各伸缩杆组包括四个的第一伸缩杆331，交叉设置的两个第一伸缩杆331为一对，该两对第一伸缩杆331相互交接。
所述第二伸缩组件34的伸缩状态与第一伸缩组件33的伸缩状态同步。所述第二伸缩组件34包括两个第二伸缩杆341，每个第二伸缩杆341包括至少两个空心管3411，且两个空心管3411直径不相同，直径小的空心管3411可穿插在大直径空心管3411内，当存在外力推拉的情况下，可实现小直径的空心管3411在大直径的空心管3411内做伸出或者缩进的操作，从而实现第二伸缩杆341伸长与缩短。图1中，每个第二伸缩杆341包括三个空心管3411。
综上，本发明的酸雨防护系统可通过雨水采集器1对雨水进行采集，然后通过雨水监控仪2对采集的雨水进行检测，并根据检测的结 果来控制电机4的工作进，若检测的到的是酸雨可控制电机4启动将伸缩支架3及雨棚5打开，通过雨棚5对酸雨进行阻挡达到防护雨棚5下方土壤及植物的效果。
对本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及形变，而所有的这些改变以及形变都应该属于本发明权利要求的保护范围之内。
