为什么要买这个呢？当然是要先货比三家

之前买了一个风力发电的小风扇。所以这次就不用开箱了。

就是这个玩意儿。日常使用微风就能转动发光，这个倒是没什么问题。

但是如果把它装在电动车上，就会出现问题。

1.货比三家

会出现什么问题？

就是它的塑料风扇会自动碎裂。换了几个新的小风扇以后，它还是会自动碎裂。最后我要把这个风扇叶子剪小一点，面积剪小一点。还是碎的。

看了另外一款风力发电。

要么太大，要么太贵，怎么也没有这个9块9的便宜。

还有下面这种奇形怪状。

那就把已有的产品进行改造吧。

2.第1次改

先重复一下原因。

之前这种风力发电的风扇有个巨大的问题，就是风速过高的时候，扇叶的就会碎裂。换了几次的都是这个效果。

那么就买一个螺旋桨吧。

电动螺旋桨。可是这里碰到一个问题。就是电动螺旋桨是分正转和反转的。

没办法区分，那就一样买一个吧。

买了一个正，一个反转。

那么到底是用哪个？

这个简单，对它吹一下就行。

哪个方向和现在已有的风扇的方向相同就行了。

最后选的，这个顺时针转。

方向与这个扇叶子推动的方向相同。

体积要小很多。

但是结构非常坚实。

为什么这么说呢？因为这个是螺旋桨呀，是要在水里面推动船前进。

必须，必须要坚固耐用。

质量杠杠的。

那么就把它装上去。

装上去的时候又发现一个问题。

两个孔径大小不一样。虽然孔径大小特别相似，但就是差那么一点点。这个原装的应该是0.5毫米左右，但是它这一款大概有0.8毫米。

我说的是这个内孔的直径。没办法，只能用螺丝胶固定一下。

这个时候就发现自己知识的浅薄了。

螺丝胶这种东西是厌氧胶水。

必须要在密闭的情况下才能凝固，而在空气接触的情况下一直就是水。

尝试着固定了一下，发现完全没有用。

先装上去看一晚上。

过了1夜之后发现。还是没有用。

过了一晚上他还是松动的，这个胶水不凝固的。

3.二次改造

那就没办法了，直接上502胶水吧。

直接涂上去就行。

不过想的太简单。

最后又出现问题。

因为这个502是直接涂到杆子上去。

最后把这个马达给凝固了

等到完全干燥以后，马达转不动。

废了，废了。

又要重新买一个。

这个时候螺旋桨已经没问题了，它里面的缝隙已经被填住了，可以直接塞好。

就是浪费了一个马达。

正好大概是这个样子。

直接贴到前轮

看一下细节。

坚固耐用。

这就是本次改造的目的。

螺旋桨总不会碎了吧？

那么实际效果怎么样？

装好了之后做个gif。

让大家看一下实际的效果。

实际效果放在最后一张。

大概就这么安装粘贴就好了。

可以看到当速度达到一定的时候，才能发出绿色的光芒

石蓓梅3207船的概念是什么 -
桓雁货18930427328 ______ 利用机器推进的大船都可称为轮船.小一点的船叫小船(舟或艇).每一只轮船都有一个叫船身的身体.早期的轮船是木制的,在船两侧或尾部装有带桨板的轮子,用人力转动轮子,桨板向后拨水使船前进.现在的轮船,船身多用金属制成,以...

石蓓梅3207有谁知道船舶螺旋推进器结构?帮帮忙,急用谢谢!
桓雁货18930427328 ______ 螺旋桨你见过吧...螺旋桨被原动机主轴带动转起来就会把水住船后推(跟随电风扇原理差不多),从而获得反作用力,螺旋桨尾轴把这个力传给推力轴承,从而推动船体前进. 由于电机的输出轴要垂直于螺旋桨面,而螺旋桨必须完全浸没,且要保证线路不能浇上水.如果船比较小,电机安在水线上稍向后倾斜放置(最佳角度跟船的重量、电机的功率等有关,可多次实验以取最好角度),此时螺旋桨就不是垂直水流了,但其有向上的分力,可减小船舶的阻力.电机输出轴直接接螺旋桨,要保证水封,以防有水顺轴浸入电机.如果保证不了,电机还是放在水上好.

石蓓梅3207跪求各位大神,轮船的前进和拐弯的驱动形式是什么?能不能具体一点?附图的话最好了~ -
桓雁货18930427328 ______ 轮船要分了,货轮和游轮.轮船都是螺旋桨推进,一般而言,货轮的变向都是后舵控制方向,不排除豪华货轮有变向推进器,自我泊船的.一般游轮也是螺旋桨推经,通畅会有变向的螺旋桨推进器或者小型变向推进器,实现自我泊船.

石蓓梅3207什么是双距螺旋桨!是怎样的构造…?和变距螺旋桨有什么不同?能用在轻型飞机上吗? -
桓雁货18930427328 ______ 前者简单的说就是双桨共轴,但力矩不等.通过改变转角控制飞机的速度.而后靠改变每个桨叶的倾斜角来改变输出扭矩,即转速的不变情况下改变推力.在旋翼机上变矩只起到调节作用,以调整节流阀来控制引擎输出功率.

石蓓梅3207为什么轮船螺旋桨在水中低速旋转效率才高 -
桓雁货18930427328 ______ 1.轮船的动力来源 可以来自两种不同的机器:涡轮机和蒸汽机. 蒸汽机由三个部分组成:蒸汽炉、汽缸和冷凝器.在蒸汽炉中,通过燃烧过程水沸腾为蒸汽.通过管道蒸汽被送到汽缸.阀门控制蒸汽到达汽缸的时间.蒸汽在汽缸内推动活塞做...

石蓓梅3207雪龙号极地考察船的船舶设计 -
桓雁货18930427328 ______ 该船原设计为北极地区多用途运输船,经升级改造后,“雪龙”号主甲板以上的所有设备设施全部更新.船上的洁净实验室面积也从原来的200多平方米扩大到580平方米,并全部更换了实验室设备,还新建了大气取样室、数据处理中心、样品...

石蓓梅3207船模螺旋桨怎么制作啊?怎么才能让它的推力更大?用什么材料耐用而且推力大? -
桓雁货18930427328 ______ 个人制作螺旋桨,讲不了太多的高科技,因为我们没那个条件,所以我建议就用钣金下料和焊接.螺旋桨形状我们可以选电风扇为参考,注意不是吊扇,而是台式,落地式,或者壁挂,需要高速旋转带安全网罩的那种,用一个轴焊接三个叶片,...

石蓓梅3207船舶螺旋桨有哪些优点?
桓雁货18930427328 ______ 1829年,奥地利人约瑟夫•莱塞尔发明了可实用的船舶螺旋桨,克服了明轮推进效率低、易受风浪损坏的缺点.此后螺旋桨推进器逐渐取代了明轮.

石蓓梅3207为什么船常被叫做轮船
桓雁货18930427328 ______ 首先说＂轮＂字,过去把用机器推进的船称为轮船,因为那时的船舶带有“轮子”.当蒸汽机发明后用在船上,蒸汽机通过装在船的两侧或船尾部的轮状推进装置推进船舶...

石蓓梅3207船舶螺旋桨中图谱桨的代号含义,比如MAU系列桨的MAU4 - 55,4代表桨叶数,55代表什么? -
桓雁货18930427328 ______ 代表盘面比,55的意思是盘面比为0.55
