本发明涉及农业技术领域，特别是涉及一种可展开收放的气囊部件、控制方法、气囊装置及透光室。
背景技术
农业生产在经济建设和社会发展中占有举足轻重的地位，良好的气候与生态环境条件是农业生产的重要保障，发展现代化农业和生态农业是今后农业发展的趋势。随着农业的现代化进程逐步加快，各类农业大棚日益普及，例如玻璃温室大棚、透明气膜大棚等农业大棚，这些建筑物由于需要具备透光性能，所以在夏天时农业大棚的内腔空间会因光照具有较高的环境温度，工作人员待在农业大棚的内腔空间会觉得又热又晒，现有技术中，通常可以采用空调制冷，但是空调制冷的方式能耗较大，而且制冷效果一般，尤其对于中小农业户来说，这种制冷方式的成本较高，也可以采用在大棚顶部覆盖遮光帘的方式降温，需要光照时再将遮光帘揭开，这样做不仅费时费力，而且遇大风等天气会将遮光帘吹走。
发明内容
基于此，有必要针对透光性建筑物因光照而温度较高的技术问题，提供一种可展开收放的气囊部件、控制方法、气囊装置及透光室。
本发明提供了一种可展开收放的气囊部件，包括：
气囊部，所述气囊部填充从气囊控制部供给的气体而膨胀展开，在展开状 态具有第一反射表面积，所述气囊部通过气囊控制部放气而实现收缩，在收缩状态具有第二反射表面积；

具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进，因此本发明不受下面公开的具体实施例的限制。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。

需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“上”、“下”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
参阅图1至图12所示，本发明一实施例提供了一种可展开收放的气囊部件，包括气囊部100和气囊控制部200，所述气囊部100填充从气囊控制部200供给的气体而膨胀展开，在展开状态具有第一反射表面积120，所述气囊部100通过气囊控制部200放气而实现收缩，在收缩状态具有第二反射表面积130，所述气囊控制部200与所述气囊部100连接，所述气囊控制部200被配置为用于控制所述气囊部100在展开状态和收缩状态之间转换。
在其中一个实施例中，气囊部100可以采用柔性材料制成，尤其是柔性反射材料，反射效果好。
在其中一个实施例中，气囊部100可以采用非弹性材料，非弹性材料变形展开后相比弹性材料不会有微小气孔造成漏气的问题，可以实现气囊部充入惰性气体如二氧化碳和/或空气，另外非弹性材料频繁膨胀收缩不会产生疲劳，使用寿命长。
在其中一个实施例中，所述气囊部100具有空腔，所述空腔被配置为能够充入气体以使所述气囊部100呈展开状态，或者排放气体以使所述气囊呈收缩状态，此时气囊可以采用柔性薄膜等柔性材料制成，在充入气体或排放气体后可以相应的改变自身的反射表面积，进而实现在展开状态和收缩状态的变换，优选采用非弹性的柔性反射材料，经过多次实验发现非弹性材料相比弹性材料通过充气膨胀到同样大小，需要的气压更低，对充气的泵体的要求较低，常规 技术下充气的泵体能提供的气压越低，充气速度越快，可以实现大体积的多个气囊部充气，此外非弹性材料变形展开后相比弹性材料不会有微小气孔造成漏气的问题，可以实现气囊部充入惰性气体如二氧化碳和/或空气，非弹性材料频繁膨胀收缩不会产生疲劳，使用寿命长。
气囊部100的可反光(光反射)效果可以基于气囊部100的本身，也可以通过其他结构辅助形成，例如在其中一个实施例中，气囊部100可以直接采用具有反光效果的材料，或者，也可以在气囊部100的外表面附加反光膜层，可以直接在所述气囊部的外表面的至少一部分表面区域设置反射膜层，或者在所述气囊的整个外表面设置反射膜层，如覆有铝或其它金属涂层的PET薄膜，PA，PVC或其他复合薄膜，本领域技术人员可以根据需求选择合适的结构和材料，在此不做限定。
在其中一个实施例中，所述气体可以为空气、二氧化碳或者空气和二氧化碳的混合物，其中，二氧化碳的保温隔热效果好，又可以有效地防止火灾危险，而空气具有获取容易、成本低的优点，本领域技术人员可以根据需求选择合适的物质作为气体，在此不做限定。
如图2和图3所示，气囊部100在展开状态和收缩状态之间转换的过程中，具有过程的变化，且展开状态和收缩状态也可以分别对应于气囊部100在展开状态和收缩状态之间转换的过程中具备的多个状态程度，例如展开状态可以为极限展开状态，或者展开程度为80％-100％之间的任意状态，如展开程度为80％、85％、90％、95％或100％等，同时，收缩状态可以为极限收缩状态，或者收缩程度为60％-0％之间的任意状态，如收缩程度为0％、5％、10％、15％、20％、25％、30％、35％、40％、45％、50％、55％、60％等，收缩状态还可以为气囊部100的自然放气状态或极限放气状态，自然放气状态即表示气囊部100空腔内的气体排放过程 中，当气囊部100的空腔内的气压和气囊部100外的大气压相同时，所述气囊部100可以呈自然下垂的状态，极限放气状态即表示气囊部100空腔内的气体排放尽，使气囊部100仅构成一根长条状或长片状的状态，气囊部100采用不同结构形式时，本领域技术人员可以根据需求限定其展开状态和收缩状态，在此不做限定。
气囊部100的展开状态和收缩状态可以进行程度上的调整，即可以调整气囊部100展开的程度或收缩的程度，在其中一个实施例中，气囊部100为气囊时，气囊部100的展开状态和收缩状态的程度可以通过控制充入或排放气体的量进行控制，或者参考图4所示，还可以在所述气囊部100上具有至少一个约束部110，约束部110具有对气囊部100相应位置形成约束的效果，因此所述约束部110可以被配置为用于改变所述第一反射表面积120的部分区域的反射角度，进而增大所述第一反射表面积120的水平反射面积，需要说明的是，当气囊部100被充入气体时，气囊部100会向四面八方整体展开，因此所述气囊部100在展开状态时具有第一反射表面积120中，只有一部分区域会形成反射效果，即水平反射面积，一旦设置了约束部110，约束部110会对其所在的位置形成约束，例如，约束部110可以约束气囊在约束部110处展开，形成该处横截面垂直轴小于水平轴的形状，例如横截面形状呈水平轴长度b大于垂直轴长度h，从而扩大水平方向的面积，进而增加气囊的水平反射面积，这样便可以改变所述第一反射表面积120的部分区域的反射角度，使原本朝向侧方展开的部分转变为朝向上方或下方，进而增大所述第一反射表面积120的水平反射面积。
约束部110可以是气囊制造过程中形成的一体结构，例如在其中一个实施例中，所述气囊部100可以包括至少两个囊片，至少两个所述囊片相互密封连接构成具有空腔的所述气囊，此时，相邻所述囊片之间的某些位置可以相互连 接起来构成约束部110，连接方式可以是粘合，不做限定，相同重量相同展开面积相同材料制成的气囊部100中，由于约束部110的存在，横截面形状呈水平轴长度b大于垂直轴长度h，其水平外表面面积相对于没有约束部110的气囊的水平外表面面积更大，可以更大范围的将透射进透明气膜农业大棚内可见光反射出去，节约材料，更经济。
约束部110可以采用各种结构形式，例如点状、条状等，例如在其中一个实施例中，参考图4所示，所述气囊部100可以沿着其纵向方向间隔设置多个点状的约束部110，且多个点状的约束部110可以呈直线或曲线排布，所述气囊部100可以沿着其横向方向对称设置点状的约束部110，因此当所述气囊部100充入气体后，约束部110可以对气囊部100的相应位置进行约束，实现水平反射面积的增大，本领域技术人员可以根据需求选择约束部110的结构形状、排布方式等，在此不做限定。
参考图4、5所示，气囊部100的结构形状可以是不规则的也可以是规则的，假设气囊部100横截面为云朵时，假设气囊部100的长度为a、宽度为b、高为h，气囊部100的长度a可以根据应用的透光室的情况进行调整，如透光室为透明气膜农业大棚时，可以根据透明气膜农业大棚的情况进行灵活设计，使气囊部100的长度a不超过透明气膜农业大棚的开间宽度，满足气囊部100能够在在透明气膜农业大棚的开间宽度上稳定装配。
气囊控制部200可以根据气囊部100的具体结构形式针对性设置，气囊控制部200可以根据需求采用各种结构形式，在其中一个实施例中，气囊控制部200包括泵体和管道，所述管道的一端与所述泵体连通，所述管道的另一端与气囊部100连通，所述泵体被配置为用于通过所述管道向气囊部100充入和/或排放所述气体，其中，泵体可以为一个或多个，例如泵体同时具备气体的充入和 排放功能时，泵体可以直接通过管道与气囊连通，当泵体仅具备气体的充入功能，或仅具备气体的排放功能时，泵体可以为两个，两个泵体分别通过不同的管道与气囊部100连通，一个泵体实现气体的充入，一个泵体实现气体的排放，而且，管道可以采用硬质或软质管道，而且气囊在展开状态至自然放气状态的放气过程中，也可以不采用泵体进行抽气，而是自然放气，此时气囊控制部200可以包括泄气阀，泄气阀安装在气囊上，打开泄气阀，气囊会直接向透明气膜农业大棚放出二氧化碳气体或空气或两者混合气体，实现自由放气，尤其是当放出的气体是二氧化碳时，可以增加大棚内二氧化碳浓度，提高农作物的光合作用，且防止火灾危险。
气囊部100可以采用一个单独使用，或采用多个形成配合，例如将多个气囊部100呈水平直线的形状悬挂在透光室的内部，或者将多个气囊部100呈斜向直线的形状悬挂在透光室的内部，使多个气囊部100与地面成一定角度布置，或者还可以将气囊部100构成为符合透光室顶棚形状的弧形、波浪形、曲线形等任意结构形式，使多个气囊部100并排放置在透光室内以覆盖大部分地面。同时，利用气囊控制部200与气囊部100配合使用时，也可以将一个气囊部100配合一个气囊控制部200进行一一控制，或者也可以将多个气囊部100共同配置一个气囊控制部200进行整体控制，本领域技术人员可以根据需求灵活设计，而且，当若干气囊部100转换为展开状态后，不同气囊部100之间可以有间距，也可以没有间距，这可以根据农作物的需求和当地光照条件，确定多个气囊部100的实际分布间距，以满足各种作物不同的光照需求。
而且，气囊控制部200还可以包括气压感应器、温度感应器和光照度感应器等，利用气压感应器、温度感应器和光照度感应器探测透光室的内腔空间环境中的气压、温度和光照度，作为调节多个气囊部100改变自身状态的依据， 控制多个气囊部100的反光效果，达到透光室的内腔空间(室内)降温或保温的目的。
气囊部100具有反射功能，可以反射阳光或其他光线，因此只要透光室具有一定程度的透光性，气囊部100均可以得以应用，例如透光室为透明气膜农业大棚时，当透明气膜农业大棚内不需要光照时，可以通过气囊控制部控制气囊部100向展开状态转换，以便使气囊部100增大自身的体积，获得面积较大的第一反射表面积120，气囊部100具有第一反射表面积120后可以将较多透射进透明气膜农业大棚内的可见光反射出去，从而达到减少光照防晒，以及降低透明气膜农业大棚内温度的目的。在夜间，气囊部100具有第一反射表面积120后可以将地面散发的热辐射反射回去，从而达到透明气膜农业大棚保温的目的，尤其气囊部100的空腔内如果充入二氧化碳，还能够利用二氧化碳获取更好的保温隔热效果。
当透明气膜农业大棚需要光照时，气囊控制部200可以控制气囊部100从展开状态向收缩状态转换，使得第一反射表面积120减小为第二反射表面积130，以便气囊部100减小自身的体积，从而获得面积较小的第二反射表面积130，气囊部100具有第二反射表面积130后可以降低对阳光的反射，使阳光透射进透明气膜农业大棚内到达地面。例如，当气囊部100如果因排放气体而泄气，呈自然下垂状态，那么阳光透射进透明气膜农业大棚内绝大部分(可达95％以上)会到达地面，当气囊部100继续排放气体使气囊部100转换为收缩状态时，气囊可以完全收缩为最小，成一根长条状或长片状构件，此时光照面积几乎不受遮挡或反射，与不设置气囊部100时的光照面积基本一致，可以为透明气膜农业大棚的内腔空间410作物生长提供充分的光照。从工程实践角度，经多次实验，气囊部100的收缩状态为自然下垂状态时，既满足透明气膜农业大棚的内 腔空间410作物生长的光照要求，又降低了对气囊控制部200的要求，提高了气囊控制部200的使用寿命，若自然下垂效果不好，可以在气囊部100下端设置配重，使得气囊部100放气(或排气)后，当其内部的气压和气囊部外的大气压相同时，所述气囊部自然下垂，满足透明气膜农业大棚的内腔空间410作物生长的光照要求。
本发明还提供了一种可展开收放的气囊部件控制方法，其气囊控制部执行的工序包括：
S1,给气囊部供给气体使得所述气囊部膨胀展开，在展开状态具有第一反射表面积120；
S2,给气囊部放气使得所述气囊部实现收缩，在收缩状态具有第二反射表面积130。
上述步骤S1和步骤S2没有先后顺序。
本发明还提供了一种气囊装置，包括所述可展开收放的气囊部件和吊装组件300，所述吊装组件300与所述可展开收放的气囊部件连接，所述吊装组件300被配置为用于吊装所述可展开收放的气囊部件，吊装组件300可以包括多个相互配合的部件，例如吊装组件300可以包括吊装件310和连接件320，吊装件310作为示例性说明可以是绳索，吊装件310负责装配在透光室的内腔空间410中，尤其是可以设置在内腔空间410的顶棚，连接件320根据气囊部100的长度设置多个，作为示例性说明可以是吊索，进而将可展开收放的气囊部件与吊装件310连接，实现对可展开收放的气囊部件的吊装。由于所述可展开收放的气囊部件的具体结构、功能原理以及技术效果均在前文详述，在此便不再赘述，任何有关于所述可展开收放的气囊部件的技术内容均可参考前文的记载。
