真空升空体 Vacuum lift
本发明涉及一种升空体的碰，具体地说，是一种真空升空体。The invention relates to a bump of a levitation body, in particular to a vacuum levitation body.
人们已经制成升空气球， 用来庆贺、作宣传， 甚至携带空间实验或探测物体。 但由于使用氢气充气， 纖、 麻烦，危险。也有用氦气、 热气球，鍵本太 高。 People have made lift balloons to celebrate, advertise, and even carry space experiments or detect objects. However, due to the use of hydrogen gas filling, it is troublesome and dangerous. Also useful are helium, hot air balloons, and the keys are too high.
本发明的目的是»—种安全、成本低的升空体。 The object of the present invention is to provide a safe and low cost aerial vehicle.
本发明的技术 方案是： The technical solution of the present invention is:
本发明的真空升空体， 由形变小的轻 M 料做成薄夕 体，其内抽真空。 因为 通常的氢气球是由于氢气的比重只为空气比重的 1/15， 因而能升空， 且 3米直径的 氢气球可挂重量约 30斤， 因此只要将气球内的空气抽掉 14/ 15， 即构成只有 1/15的 ^气体的真空球体， 其内部的气体的比重就比氢气小了， 因而，具有升空能力。 如上舰，本发明的实现是： 其主要包括一个夕 h¾体， 且在其上设一抽气头， 以及该抽气头封闭件， 并对该夕 体内部抽真空， 气头封闭。 The vacuum levitation body of the present invention is made of a thin M material with a small deformation, and a vacuum is evacuated therein. Because the normal hydrogen balloon is because the specific gravity of hydrogen is only 1/15 of that of air, it can be lifted off, and a 3 meter diameter hydrogen balloon can hang about 30 kg, so as long as the air in the balloon is pumped out 14/15 That is, the vacuum sphere that constitutes only 1/15 of the gas, the specific gravity of the gas inside it is smaller than that of hydrogen, so it has the ability to lift off. As above, the present invention is realized as follows: It mainly includes a body and a suction head is provided thereon, and the suction head closure is evacuated to close the inside of the body.
本发明的优点是： 1、成本低， 与已有的氦升空气球相比， 其造价有明显的差 别； 2、 使用安全， 不像已有氢气升空气球那样存在易燃易 缺点， 3、制^ 便，应用现代的抽真空技术， 能十分容易地将其抽到 10-2的真空度。The advantages of the invention are: 1. Low cost, compared with the existing helium balloon, its cost is obviously different; 2. Safe to use, unlike the existing flammable and flammable shortcomings of the existing hydrogen balloon, 3 , the system will ^, the application of modern vacuum technology, can very easily be drawn into the vacuum of10-2.
本发明的附图简述如下： The drawings of the present invention are briefly described as follows:

根据附图给出本发明实施例， 以便 ¾ ^步明了本发明的结构，并结合对实 施例的描述， ¾ ^步 发明的技术细节。 The embodiments of the present invention are given according to the accompanying drawings, so as to clarify the structure of the present invention step by step, and in combination with the description of the embodiment, the technical details of the step invention.
阅图 1， 如图 J^， 本发明包括夕 体1， 在该夕 (¾体1上设一抽气头 2, 和该抽气头 2的封闭件 3 , 打开封闭件 3后将该夕 [^体 1抽成真空后 气头 2封闭。 Referring to FIG. 1, as shown in FIG. 1, the present invention includes a body 1, and a suction head 2 is provided on the body 1, and a closure member 3 of the suction head 2 is opened after the closure member 3 is opened. [^ After body 1 is evacuated, the gas head 2 is closed.
本实施例采用 1毫米厚钢板制成直径 4(«形夕 1， 将其抽成真空体， 真空 AIn this embodiment, a 1 mm thick steel plate is used to make a diameter of 4 («shaped evening 1, which is evacuated into a vacuum, and the vacuum A
