具体实施方式
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体实施方式以及附图说明，进一步阐述本发明的优选实施方案。
实施例1：
请参阅图1-图5：
一种天然气储存罐，其结构包括储存筒1、通气阀2、固定块3、底板4，所述储存筒1通过焊接连接于底板4上方，所述通气阀2安装在储存筒1左侧，所述固定块3通过焊接连接于储存筒1顶部，所述储存筒1包括支撑杆11、浮板12、隔离板13、橡胶板14、弹簧15，所述支撑杆11安装在储存筒1内部，所述浮板12嵌设于支撑杆11外侧，所述隔离板13两端通过焊接连接于储存筒1内底部且安装在支撑杆11底部，所述橡胶板14嵌固于隔离板13上表面，所述弹簧15安装在隔离板13底部与储存筒1内底部，所述支撑杆11有五根且贯穿浮板12内部，并且隔离板13两端为曲状，避免浮板12发生偏移。
图中，所述支撑杆11包括限位筒111、固定杆112、滑槽113，所述限位筒111安装在支撑杆11四周，所述固定杆112嵌固于限位筒111内部，所述滑槽113嵌设于限位筒111外表面，所述固定杆112与固定块3相连，利于稳定支撑杆11，避免支撑杆11倾斜。
图中，所述浮板12包括夹环121、通孔122、滑轮123，所述夹环121嵌固于浮板12内部，所述通孔122嵌设于夹环121内侧，所述滑轮123安装在通孔122表面，所述通孔122通过间隙连接于限位筒111外表面且滑轮123在滑槽113上移动，利于根据储存筒1内液化天然气的多少改变浮板12的位置。
图中，所述夹环121包括定位杆a1、卡栓a2，所述定位杆a1通过焊接连接于夹环121内部，所述卡栓a2活动卡合连接于定位杆a1中段，所述卡栓a2有两块且位于滑轮123两侧，利于将滑轮123固定在夹环121内侧。
本实施例的具体原理：将储存筒1安装在底板4上，打开通气阀2往储存筒1装入液化天然气，弹簧15上的隔离板13与固定块3将支撑杆11安装在储存筒1内，支撑杆11表面的浮板12浮在液化天然气上方，跟随储存筒1内液化天然气的多少浮板12的位置会改变，此时浮板12内部的滑轮123在支撑杆11的滑槽113上移动，使浮板12始终水平置于液化天然气上表面，避免在运输过程中，储存筒1内的液化天然气会摇晃与储存筒1内壁摩擦，避免液化天然气受热燃爆。
实施例2：
请参阅图6-图7：
图中，所述通气阀2包括盖子21、转轴22、阀盖23，所述盖子21安装在通气阀2左侧，所述转轴22间隙连接于盖子21上方，所述阀盖23安装在通气阀2右侧，所述盖子21为半球形，并且阀盖23焊接在储存筒1右端，利于往储存筒1内存取液化天然气。
图中，所述阀盖23包括拉紧簧b1、铰链b2、阀门b3、固定板b4，所述拉紧簧b1通过焊接连接阀盖23与铰链b2，所述铰链b2右上壁紧贴盖子21上内壁，所述阀门b3安装在阀盖23中部，所述固定板b4焊接在阀盖23底部，所述铰链b2绕转轴22转动，利于控制盖子21的开合。
图中，所述固定板b4包括气压缸b41、压块b42、夹板b43、卡块b44，所述气压缸b41嵌设于固定板b4内部，所述压块b42间隙连接于固定板b4右侧，所述夹板b43通过焊接连接于气压缸b41一侧，所述卡块b44配合安装于夹板b43内侧，所述左侧卡块b44与盖子21底部末端相焊接，且卡块b44末端为菱形，并且夹板b43末端截面为三角形，利于将盖子21进行固定。
本实施例的具体原理：在拉紧簧b1拉动铰链b2带动盖子21绕转轴22下转，使盖子21底部末端的卡块b44卡入夹板b43内侧，从而将通气阀2关闭，避免运输过程中液化天然气泄漏，当需要存取液化天然气时，按下压块b42挤压气压缸b41，使气压缸b41内的气压推动盖子21底部向外弹出，此时卡块b44脱离夹板b43，然后绕转轴22即可打开盖子21，通过阀门b3进行存取液化天然气。

1.一种天然气储存罐，其结构包括储存筒(1)、通气阀(2)、固定块(3)、底板(4)，所述储存筒(1)通过焊接连接于底板(4)上方，所述通气阀(2)安装在储存筒(1)左侧，所述固定块(3)通过焊接连接于储存筒(1)顶部，其特征在于：所述储存筒(1)包括支撑杆(11)、浮板(12)、隔离板(13)、橡胶板(14)、弹簧(15)，所述支撑杆(11)安装在储存筒(1)内部，所述浮板(12)嵌设于支撑杆(11)外侧，所述隔离板(13)两端通过焊接连接于储存筒(1)内底部且安装在支撑杆(11)底部，所述橡胶板(14)嵌固于隔离板(13)上表面，所述弹簧(15)安装在隔离板(13)底部与储存筒(1)内底部；所述支撑杆(11)包括限位筒(111)、固定杆(112)、滑槽(113)，所述限位筒(111)安装在支撑杆(11)四周，所述固定杆(112)嵌固于限位筒(111)内部，所述滑槽(113)嵌设于限位筒(111)外表面；所述浮板(12)包括夹环(121)、通孔(122)、滑轮(123)，所述夹环(121)嵌固于浮板(12)内部，所述通孔(122)嵌设于夹环(121)内侧，所述滑轮(123)安装在通孔(122)表面；所述夹环(121)包括定位杆(a1)、卡栓(a2)，所述定位杆(a1)通过焊接连接于夹环(121)内部，所述卡栓(a2)活动卡合连接于定位杆(a1)中段；所述通气阀(2)包括盖子(21)、转轴(22)、阀盖(23)，所述盖子(21)安装在通气阀(2)左侧，所述转轴(22)间隙连接于盖子(21)上方，所述阀盖(23)安装在通气阀(2)右侧；所述阀盖(23)包括拉紧簧(b1)、铰链(b2)、阀门(b3)、固定板(b4)，所述拉紧簧(b1)通过焊接连接阀盖(23)与铰链(b2)，所述铰链(b2)右上壁紧贴盖子(21)上内壁，所述阀门(b3)安装在阀盖(23)中部，所述固定板(b4)焊接在阀盖(23)底部；所述固定板(b4)包括气压缸(b41)、压块(b42)、夹板(b43)、卡块(b44)，所述气压缸(b41)嵌设于固定板(b4)内部，所述压块(b42)间隙连接于固定板(b4)右侧，所述夹板(b43)通过焊接连接于气压缸(b41)一侧，所述卡块(b44)配合安装于夹板(b43)内侧。
2.根据权利要求1所述的一种天然气储存罐，其特征在于：将储存筒(1)安装在底板(4)上，打开通气阀(2)往储存筒(1)装入液化天然气，弹簧(15)上的隔离板(13)与固定块(3)将支撑杆(11)安装在储存筒(1)内，支撑杆(11)表面的浮板(12)浮在液化天然气上方，跟随储存筒(1)内液化天然气的多少,浮板(12)的位置会改变，此时浮板(12)内部的滑轮(123)在支撑杆(11)的滑槽(113)上移动，使浮板(12)始终水平置于液化天然气上表面，避免在运输过程中，储存筒(1)内的液化天然气会摇晃与储存筒(1)内壁摩擦，避免液化天然气受热燃爆，在拉紧簧(b1)拉动铰链(b2)带动盖子(21)绕转轴(22)下转，使盖子(21)底部末端的卡块(b44)卡入夹板(b43)内侧，从而将通气阀(2)关闭，避免运输过程中液化天然气泄漏，当需要存取液化天然气时，按下压块(b42)挤压气压缸(b41)，使气压缸(b41)内的气压推动盖子(21)底部向外弹出，此时卡块(b44)脱离夹板(b43)，然后绕转轴(22)即可打开盖子(21)，通过阀门(b3)进行存取液化天然气。
