具体实施方式
本发明是一种集发电送风功能于一体的风力发电机，可适用于海洋、陆地以及城市群中，其功能在于实现风力发电的同时，可利用电能送风，以满足在无风时需要送风的需求，提高风机经济效益。该风力发电机的高度以及大小可根据使用需求以及使用场合进行调整。
如图1-3所示，包括扩张式旋翼1以及容置腔体，所述扩张式旋翼1与转动轴18的一端固定连接，使得当转动轴18转动时可带动扩张式旋翼1一起转动，所述扩张式旋翼1具有可收缩功能，能够根据需求进行扩张和收缩以满足风能与机械能的相互转换；所述转动轴18的另一端伸入容置腔体内、与容置腔体转动连接；所述容置腔体内，从转动轴18到电网11依次连接有减速器3、可逆电机5、变压器10，所述可逆电机5与变压器10电性连接，所述变压器10可设置在容置腔体内，或者设置在容置腔体外部以使得容置腔体体积更加小巧，所述变压器10安装于电网11前端，其功能在于输电变压，实现并网，所述电网11位于变压器10后端，其功能在于将转换的电能进行传输。
所述可逆电机5上设置有顺逆转控制器9，顺逆转控制器9可控制可逆电机5实现机械能与电能的双向转换，从而选择发电、送风的不同模式；所述减速器3与可逆电机5之间设置有转速传感器4，转速传感器4可采集扩张式旋翼1的转速，所述可逆电机5后端设置有功率传感器6，可采集可逆电机5的功率数据。可逆电机5与顺逆转控制器9皆可采用现有技术中所有的，适用于风力发电的。
所述容置腔体内还设置有控制系统8，所述控制系统8与转速传感器4、功率传感器6、顺逆转控制器9电性连接；所述容置腔体外表面上侧设置有测风仪7，所述测风仪7上设置有气象专用传感器，气象专用传感器可测量风速、风向等数据，所述气象专用传感器与控制系统8电性连接。
控制系统8获取来自转速传感器4、功率传感器6、气象专用传感器所测量的相应数据，当测风仪7测得的风速较低时，控制系统8根据预先设置好的数据控制顺逆转控制器9，使得可逆电机5处于送风模式，此时风机将储存的电能转换为机械能。吹风工作时，电能由电网11传入，经变压器10、顺逆转控制器9对发电、送风模式进行控制选择后，电能经可逆电机5，利用可逆电机5磁场对电流作用将电能转换为机械能，并传入减速器3，减速器3利用齿轮结构对转速进行调整控制，转速调整后，机械能传至扩张式旋翼1，推动扩张式旋翼1旋转，产生风能，从而实现机械能到风能的转换。
当测风仪测得的风速较高达到一定数值时，控制系统8控制顺逆转控制器9使得可逆电机5，使其处于发电模式，将风能转换为电能储存起来。发电工作时，在有风条件下，风力推动扩张式旋翼1开始旋转，扩张式旋翼1旋转后带动转动轴18旋转，由此实现将风能转换成机械能，转动轴18连接扩张式旋翼1与减速器3，通过转动轴18将扩张式旋翼1上的机械能传递给减速器3，减速器3利用齿轮结构对转速进行调整控制，转速调整后，机械能传至可逆电机5，可逆电机5依靠电磁感应产生电能，由此机械能通过可逆电机5转换为电能，电能传至变压器10，通过变压器10对输变电压进行调整，再经顺逆转控制器9对发电、送风模式进行控制选择后，并入电网11，最终实现电能输送。
控制系统8也可同时获取测风仪7和转速传感器4的数据，根据预先设置的数值，从而控制顺逆转控制器9使得可逆电机5在送风、发电模式之间转换。当测风仪7测得的风速较低、扩张式旋翼1的转速也较 低或没有转速时，此时可逆电机5处于送风模式；当测风仪7测得的风速以及扩张式旋翼1的转速达到一定数值，使得风机不能继续运行在送风模式时，可逆电机5处于发电模式。当可逆电机5的功率过大时，此时控制系统8控制顺逆转控制器9，使得可逆电机5停止工作。
所述转动轴18外侧设置有套筒，所述转动轴18与套筒可转动连接；所述套筒一端与扩张式旋翼1分离、另一端与容置腔体固定连接。转动轴18在套筒内，相对于套筒可无阻碍转动，套筒对转动轴18起到保护的作用。

所述每组刚性扇叶上远离棘爪16的一端设置有通孔，所述通孔中可滑动连接有钢缆14，所述钢缆14一端与远离固定扇叶13的活动扇叶19固定连接、另一端与钢缆锁紧电机15连接，所述钢缆锁紧电机15与棘轮17固定连接。当需要将活动扇叶19打开时，松开钢缆锁紧电机15，使得钢缆14呈非锁紧状态，此时活动扇叶19在重力作用下张开，活动扇叶19上的棘爪16相对棘轮17活动，活动扇叶19完全打开时，棘爪16卡在棘轮17上，使得活动扇叶19不会反向运动回固定扇叶13处；当需要将活动扇叶19收回时，通过转动轴18向活动扇叶19运动方向相反的方向转动一定角度，此时固定扇叶13带动活动扇叶19随着转动轴18一起转动，使得棘轮17与棘爪16呈分离状态，将钢缆锁紧电机15转动拉紧钢缆14，即可使得活动扇叶19收回。
所述固定扇叶13及数片活动扇叶19靠近转动轴18的一端可活动 分离也可铰连接，所述的刚性扇叶为三组。
具体工作方式为：1、转速传感器、功率传感器、测风仪、控制系统，对风机的转速、风机发电功率、以及风场中的风速进行实时采集，控制系统在对采集来的数据进行综合分析后，对顺逆转控制器发出命令；
2、顺逆转控制器具备发电、送风双模式选择控制功能，当接受到控制系统发来的命令后，顺逆转控制器开始进行模式选取。当风场风力资源充足且需要电能源时，风机通过控制系统分析后发出命令，顺逆转控制器将风机调整为发电模式；
3、在风力作用下，收紧状态下的扩张式旋翼开始旋转，风能由扩张式旋翼转换成机械能，利用传动系统将机械能传递至减速器，经减速器转速调整后，机械能传至可逆电机产生电流，电能后经过顺逆转控制器、变压器装置，实现了电能的输电变压，最终并入电网；
4、当风场风力资源匮乏且需要风能时，风机通过控制系统分析后发出命令，顺逆转控制器将风机调整为送风模式。电能由电网发出，经变压器顺逆转控制器传至可逆电机，利用可逆电机磁场对电流作用将电能转换为机械能，再经减速器进行转速调节后，利用传动系统将机械能传至扩张式旋翼，以驱动扩张状态下的扩张式旋翼旋转，产生风能。
上述实施方式是优选的实施方式，应当指出的是，上述优选实施方式不应视为对本发明的限制，本发明的保护范围应当以权利要求所限定的范围为准。对于本技术领域的普通技术人员来说，在不脱离发明的精神和范围内，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
