一、田野里的大風車是干嘛用的?

田野的風車通常是風力發電,為把風的動能轉為電能。風能是一種清潔無公害的的可再生能源能源,很早就被人們利用,主要是通過風車來抽水、磨面等。風力發電非常環保,且風能蘊量巨大,因此日益受到世界各國的重視。

風車可用于發電和磨麥子,利用風車驅動機械裝置,便能把小麥磨成粉,把玉米磨成玉米片

二、風車的寓意 風車相關介紹

1、風車象征著自由與幸福。

2、在中國來傳統文化里,又名吉祥輪、八卦風輪、四季平安符。在很多地方都有類似于風車的建筑,也成為了一道亮麗的風景線,在現代企業里風車也代表了事業蒸蒸日上的寓意。

3、風車是風力機將風能轉換為機械功的動力機械,它是一種以太陽為熱源、大氣為工作介質的熱能利用發動機;設置地點靈活、成本低,使區域性調節電力輸出成為了可能;風電效益相當大程度上取決于安裝地點的風力狀態,通過氣象測量可得到安裝地點。

三、風車磨坊的介紹

2000多年前,中國、巴比倫、波斯等國就已利用古老的風車提水灌溉、碾磨谷物,風車的作用主要是將風力轉化為槳輪轉動得來的動力,從而通過風車利用風能提水、供暖、制冷、航運、發電等,公元8世紀時在中亞已經出現了研磨谷物的風車磨坊。

四、急!!求救一篇介紹荷蘭風車的英文!

WINDMILL (MOLEN DE ROOS)

Originally there were 15 windmills within the old defensive walls of Delft, but only one survives today. This is called Molen De Roos (The Rose Windmill). It is located a short walk from the Oude Kerk (Old Church). It was used for grinding grain for bakers and barley, oats and corn for farmers. It needed extensive restoration work between 1988 and 1990, but is now back in full working order. When it is open to visitors a blue flag flies from the top of the windmill. There is no entrance charge, but voluntary donations help the Vereniging De Hollandsche Molen (The Dutch Windmill Association) to maintain the building.

Take a Virtual Windmill Tour of Windmills - by by Peter Melville

Holland is famous for its windmills, so no one will be surprised to learn that the world’s tallest windmills are to be found here. However, few Dutch, let alone tourists, will be able to tell you where they stand. And people might not even believe it when told that they are not out in the fields, but in heart of the most densely populated areas on the globe, near the second largest port in the world.

Schiedam lies to the west of Rotterdam, from where it is easily reached by public transport. Surrounded by 20th-century commercial and residential areas is the small yet charming 18th century town center, looking like a pocket-size Amsterdam. At the western edge of Schiedam’s old center, lined up along the former outer canal, stand the world’s five tallest windmills.

Their location explains their height.

When the windmills were built, between 1770 and 1803, they stood in what was then the edge of town and the industrial area. They were built for the grinding of grain needed for the distillation of gin, then Schiedam’s main industry. To catch as much wind as possible, they were made to stand high above the city, which came to lie at their feet.

In those days the canal was a moat, and the other side of the moat only flat farmland. That area started being built early in the 20th century, and now it is a semi-urban area of little architectural distinction. The result of this development for the windmills is that they are now surrounded by buildings and are part of the urban landscape. The highest windmills in the world stand in the middle of town.

These five windmills are what remain of an original twenty, the others having been made redundant by steam engines. In 1880, those twenty mills ground grain for the nearly 400 distilleries that made the famous jenever of Schiedam, where more gin was produced than in any other city in the world. Schiedam can no longer make that claim, but two of the five remaining windmills do still grind grain for the jenever industry. The blades of the other three windmills still turn as well, but only for show. Three of the five can be visited to see the interior: one houses a shop, one a museum and the third a restaurant.

In 1981 the Schiedam Windmills Society was founded. The Society’s aim is to assist in the operation and maintenance of these unique windmills, which had previously been badly neglected. In celebration of the Society’s 25th anniversary, on April 28 and 29 the blades of all five windmills will turn non-stop for 25 hours.

Let’s take a walk along the five windmills in Schiedam. Join us for the World's Tallest Windmills Virtual Tour.

荷蘭座落在地球的盛行西風帶,一年四季盛吹西風。同時它瀕臨大西洋,又是典型的海洋性氣候國家,海陸風長年不息。這就給缺乏水力、動力資源的荷蘭,提供了利用風力的優厚補償。

荷蘭的風車,最早從德國引進。開始時,風車僅用于磨粉之類。到了十六、七世紀,風車對荷蘭的經濟有著特別重大的意義。當時,荷蘭在世界的商業中,占首要地位的各種原料,從各路水道運往風車加工,其中包括:北歐各國和波羅的海沿岸各國的木材,德國的大麻子和亞麻子,印度和東南亞的肉桂和胡椒。在荷蘭的大港--鹿特丹和阿姆斯特丹的近郊,有很多風車的磨坊、鋸木廠和造紙廠。

隨著荷蘭人民圍海造陸工程的大規模開展,風車在這項艱巨的工程中發揮了巨大的作用。根據當地的濕潤多雨、風向多變的氣候特點,他們對風車進行了改革。首先是給風車配上活動的頂篷。此外,為了能四面迎風,他們又把風車的頂篷安裝在滾輪上。這種風車,被稱為荷蘭式風車(如左圖)。

荷蘭風車,最大的有好幾層樓高,風翼長達20米。有的風車,由整塊大柞木做成。十八世紀末,荷蘭全國的風車約有一萬二千架,每臺擁有6000匹馬力。這些風車用來碾谷物、粗鹽、煙葉、榨油,壓滾毛呢、毛氈、造紙,以及排除沼澤地的積水。正是這些風車不停地吸水、排水,保障了全國三分之二的土地免受沉淪和人為魚鱉的威脅。

二十世紀以來,由于蒸氣機、內燃機、渦輪機的發展,依靠風力的古老風車曾一度變得暗淡無光,幾乎被人遺忘了。但是,因為風車利用的是自然風力,沒有污染、耗盡之虞,所以它不僅被荷蘭人民一直沿用至今,而且也成為今日新能源的一種,深深地吸引著人們。

目前,荷蘭大約有兩千多架各式各樣的風車。荷蘭人很喜愛他們的風車,在民歌和諺語中常常贊美風車。風車的建筑物,總是盡量打扮得漂漂亮亮的。每逢盛大節日,風車上圍上花環,懸掛著國旗和硬紙板做的太陽和星星。
