具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。图1至图8给出了本申请的具体实施方式。
如图1至图5所示，本实施例为一种水下摄影设备，包括依次连接的主动传动箱体1、从动传动箱体2和防水摄影机10，还包括设置在从动传动箱体2内的第二磁体7以及设置在主动传动箱体1内的依次连接的电源22、马达5 和第一磁体6，第一磁体6与马达5驱动的主动轴9连接，第一磁体6和第二磁体7相对设置，第二磁体7连接有从动轴8，从动轴8贯穿从动传动箱体2的一个端面，从动轴8的一端与第二磁体7连接，另一端与防水摄影机10连接，主动传动箱体1为全密封结构，从动轴8与从动传动箱体2通过防水密封轴承连接，主动传动箱体上还设置有与电源22连接的充电口23，充电口23的防水等级为IP68。上述设置可以确保电子零件处于密封状态，不会进水，方便进行水底工作，还可以工作在高粉尘环境中。
上述水下摄影设备的具体工作过程为，电源用于为马达5供电，马达5带动设备的主动传动箱体1内的第一磁体6转动，在上下隔空的情况下以磁力带动从动传动箱体2内的第二磁体7转动，继而传送动力至从动轴8，使得从动轴8带动防水摄影机10转动。上述的传动过程可以实现无接触的传动，机械动力传递无需依靠物面间的紧密啮合或依靠相互间的接触摩擦来完成，结构简单。可以实现设备的完全密封，胜任水下工作。
作为一种可选的实施方式，防水摄影机10通过夹持机构固定连接在从动轴8上。夹持机构可以选择为凹形固定件，凹形固定件内侧安装硅胶套。硅胶套的使用保护了安装在凹形固定件上的智能设备不受损坏。
如图5和图6所示，水下摄影设备还包括设置在主动传动箱体1内的控制系统，控制系统包括控制模块11、转速模块3、转向模块4和通信模块12，其中，转速模块3与马达5连接，用于控制马达5的转速，转向模块4与马达5连接，用于控制马达5的转动方向，控制模块11与防水摄影机10连接，用于控制防水摄影机10的工作，通信模块12分别与控制模块11、转速模块3和转向模块4连接。
具体的，本实施例中转速模块和转向模块的具体工作原理可以依托现有技术的各种电路结构来实现，例如，变速可以通过调节直流电机的电压来改变电机的转速，此外还可以用脉宽调制(PWM，Pulse Width Modulation)来实现调速。方波的有效电压跟电压幅值和占空比有关，可以通过占空比实现改变有效电压。再如，变向通过改变电压极性来改变转动方向，具体的可以利用H 桥电路来改变马达的电压极性，从而改变马达的转向。通过单片机产生可控的PWM波来驱动H桥，根据需要来改变H桥中接马达的电压极性，从而改变马达的转向，通过控制单片机控制PWM的占空比，改变马达两端的有效电压，从而控制马达的转速。
具体的，控制模块11用于发送拍摄指令及选择拍摄的类型，拍摄的类型包括拍照、全景拍摄、延时摄影和镜像中的至少一种。例如，具体实施过程中，控制模块可选择的设置以下参数：拍摄时间及拍摄类型，例如7.5秒/15秒：全景拍摄(panorama)；30s/60s镜像：shortVideo；15min/60mins：延时摄影(time lapse)；或者设置为1秒/15秒：全景拍摄(panorama)；30s/60s镜像：shortVideo；1min/60mins：延时摄影(time lapse)。需要说明的是，控制模块的参数可选择的根据用户需要设置为其他数值，本实施例中仅仅为说明列举其中一种，控制模块参数包括并不限于上述数值。
具体的，本申请水下摄影设备中，通信模块12可以为蓝牙通信模块、WIFI通信模块、2.4G/3G/4G通信模块、红外线通信模块、超声波通信模块或雷达通信模块，但通信模块并不局限于上述列举的各种通信模块。
作为一种可选的实施方式，水下摄影设备还包括与通信模块12连接的遥控装置(图中未示出)。用户按下遥控装置上的按键，该按键信息通过通信模块发送到控制模块，控制模块接收到指令后，通过通信模块将该信息发送到防水摄影机，防水摄影机开始工作。
如图5所示，第一磁体6通过第一固定件19与主动轴9连接，第二磁体7通过第二固定件20与从动轴8连接，第一固定件19位于主动传动箱体1内，第二固定件20位于从动传动箱体2内。此外，从动轴8通过齿轮组21与第二磁体7或第二固定件20连接。
用户开启电源后，电池驱动马达5，带动设备内与第一磁体6连接的第一固定件19转动，并带动第一磁体6转动，在上下隔空的情况下以磁力带动第二磁体7转动，继而传送动力至与第二磁体7连接的第二固定件20，第二固定件20与齿轮组21连接，推动齿轮转动，最后将动力传至从动轴8，推使从 动轴8轴心以不同速度和方向转动。齿轮组21的设置可以通过多种齿轮的啮合组合传递扭矩、改变速度和改变扭矩方向。
第一固定件19和第二固定件20的材质为阻磁性材料，如此使得第一固定件19背离第一磁体6一侧以及第二固定件20背离第二磁体7一侧的磁感线的强度较低，增强第一磁体6与第二磁体7之间的磁力耦合。
在上述各实施例中，第一磁体6和第二磁体7可以选择为各种天然磁石，还可以为各种人造磁体，除了磁石之外，还可以选择为电磁铁。
如图8所示，作为一种较为优选的实施方式，第一磁体6和第二磁体7相对的端面上的磁极按照NS极交替方式圆周排列。本实施例中，具体的，多个磁铁呈环状布置于第一固定件上形成第一磁体，任意两个相邻的磁铁的磁极布置方向相反，如具有八个磁铁，四个磁铁磁极以N-S向布置，四个磁铁的磁极以S-N向布置，且相邻磁铁的磁极布置方向相反，同理，第二磁体在第二固定件上的布置方式按照相同原理设置。如此设置的优点在于，第一磁体与第二磁体在相对静止的过程中，任意相对的位置均为N-S极相互吸引的状态，当在第一磁体受驱动转动一周的过程中，第二磁体经历的磁感线的变化较大，同时可以得到在空间上正弦分布的磁场，获得较强的磁力耦合，增强传动效果。
为了提高磁力传动效果，主动传动箱体1和从动传动箱体2的材质均为非磁性材料。
作为一种可选的实施方式，如图7所示，水下摄影设备还包括连接在主动传动箱体1上的手柄18。
如图1至图7所示，为了方便控制，本申请水下摄影设备还可以设置控制按键，控制按键包括电源键13、与转向模块4连接正转控制键14和反转控制键15、与控制模块11连接的模式选择键16以及与转速模块3连接的转速控制键17。
具体的，
控制按键设置在主动传动箱体1的外部；或
控制按键设置在手柄18上；或
控制按键设置在遥控装置上。
进一步的，本申请水下摄影设备还设置有漏水报警系统，漏水报警系统包括设置于主动传动箱体1和/或从动传动箱体2内的触水感应器、语音报警器和设置于遥控器上的蜂鸣器，触水感应器与语音报警器连接，语音报警器和蜂鸣器连接。当设备漏水时，箱体内底部的触水感应器优先接触到水并感应，产生一个电流信号，触发语音报警器和蜂鸣器工作，反复播放预先录好的漏水声音信号，从而实现设备第一时间漏水就通知操作者的功能。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
工业实用性
本申请的水下摄影设备，可以通过第一磁体与第二磁体之间的磁耦合，实现主动轴与从动轴之间不通过直接接触便能进行力与力矩的传递，可将主动传动箱体的动密封化为静密封，实现零泄漏，增强防水功能，适合于在水下工作。
