Abstract
A solar power generation system can be expected to be installed, for example, in a desert. Installing a solar power generation system in a desert, however, is not easy. A reason for that is that dust in the desert is attached to and accumulates on the solar power generation system.
Therefore, one feature of the present invention is that dust is removed using a temperature difference.
According to the present invention, dust can be efficiently removed.

FIG.2 (b) is a figure explaining the solar energy power generation system of a present Example from the back. The solar power generation system is arranged to stand on the ground 112. The solar power generation system has a solar power generation unit 111. The solar power generation unit 111 includes a solar power generation array 107 and frames 108, 109, and 110 that hold the solar power generation array 107. A plurality of first modules 106 are arranged on the front side of the solar power generation array 107.

FIG. 9 is a diagram illustrating changes in the positions of the rotation mechanism 102 (particularly the holding unit 409) and the solar power generation unit 111 with respect to time. The vertical axis 901 in FIG. 9 represents the position, and the horizontal axis 902 represents the time.
図４の状態を初期状態とする。図４では砂漠の気温は所定時刻（図９のt0）で所定の初期温度T0であり、媒体の体積はV0であるとする。図４の状態から砂漠の気温がT1（＜T0）と変化した場合は、図５を用いて説明できる。図５では気温が低くなったため、媒体４０６の体積は減少する。その結果ピストン４０３、ロッド４０７、保持部４０９、及び保持部４０９に保持された太陽発電ユニット１１１は矢印５０１の方向へ移動する。太陽発電ユニット１１１は保持部４０９によって保持されているため、太陽発電ユニット１１１の単位時間当たりの移動量と保持部４０９の単位時間当たりの移動量は実質的に同視でき、図９では符号９０３によって表現できる。保持部４０９の第１の突起４１０が図９の時刻t1でピン４１３に接触すると、保持部４０９は矢印５０３の方向へ回転する。その結果太陽発電ユニット１１１の保持は解除され、太陽発電ユニット１１１は矢印５０２の方向へ移動することになる。太陽発電ユニット１１１は図２（a）に示すように一方の端部が回転可能なように固定されている。よって、太陽発電ユニット１１１は保持部４０９の保持が解除された瞬間からモーメントによって初期位置Y0へ戻ろうとする。t1以降の保持部４０９の移動量は砂漠の気温に依存するので符号９０４で表現でき、太陽発電ユニット１１１の移動量は符号９０５によって表現できる。
Let the state of FIG. 4 be an initial state. In FIG. 4, it is assumed that the desert air temperature is a predetermined initial temperature T 0 at a predetermined time (t 0 in FIG. 9) and the volume of the medium is V 0 . When the desert temperature changes from T 1 (<T 0 ) in the state of FIG. 4, this can be explained using FIG. In FIG. 5, the volume of the medium 406 decreases because the temperature has decreased. As a result, the piston 403, the rod 407, the holding unit 409, and the solar power generation unit 111 held by the holding unit 409 move in the direction of the arrow 501. Since the solar power generation unit 111 is held by the holding unit 409, the movement amount per unit time of the solar power generation unit 111 and the movement amount per unit time of the holding unit 409 can be substantially equated. In FIG. Can express. When the first protrusion 410 of the holding unit 409 contacts the pin 413 at time t 1 in FIG. 9, the holding unit 409 rotates in the direction of the arrow 503. As a result, the holding of the solar power generation unit 111 is released, and the solar power generation unit 111 moves in the direction of the arrow 502. As shown in FIG. 2A, the solar power generation unit 111 is fixed so that one end thereof can rotate. Therefore, the solar power generation unit 111 tries to return to the initial position Y 0 by the moment from the moment when the holding of the holding unit 409 is released. Since the movement amount of the holding unit 409 after t 1 depends on the desert temperature, it can be expressed by reference numeral 904, and the movement amount of the solar power generation unit 111 can be expressed by reference numeral 905.
その後、図９の時刻t2では、図６に示すように太陽発電ユニット１１１は板１０４に衝突する。衝突の際に発生した衝撃力（その他の表現としては力積）によって、図３に示す塵埃や太陽発電ユニット１１１に付着した塵埃は効果的に除去される。
Then, at time t 2 in FIG. 9, the solar power generation unit 111 as shown in FIG. 6 impinges on the plate 104. The dust shown in FIG. 3 and the dust attached to the solar power generation unit 111 are effectively removed by the impact force generated during the collision (in other words, impulse).
その後、図７に示すように砂漠の気温がT2（＞T1）となると、媒体４０６の体積は増加する。その結果ピストン４０３、ロッド４０７、保持部４０９は矢印７０２の方向へ移動する。保持部４０９が太陽発電ユニット１１１に接触すると、傾斜面４１２が形成されていることによって保持部４０９は矢印７０１の方向に回転する。
Then, as shown in FIG. 7, when the desert air temperature reaches T 2 (> T 1 ), the volume of the medium 406 increases. As a result, the piston 403, the rod 407, and the holding portion 409 move in the direction of the arrow 702. When the holding unit 409 comes into contact with the solar power generation unit 111, the holding unit 409 rotates in the direction of the arrow 701 due to the formation of the inclined surface 412.
そして、図８に示すように砂漠の気温がT3(≒T0)となると、太陽発電ユニット１１１は再度保持部４０９に保持される。
Then, as shown in FIG. 8, when the desert temperature reaches T 3 (≈T 0 ), the solar power generation unit 111 is held by the holding unit 409 again.
このように実施例１は砂漠の気温に応じて太陽発電ユニット１１１をその一部を回転中心として回転させること（その他の表現としてはモーメントを発生させることで）で人手によらず塵埃を除去できる。また、衝撃力（その他の表現としては力積）を利用することで単純に太陽発電ユニット１１１を揺らすよりも効果的に塵埃を除去できる。
As described above, according to the first embodiment, dust can be removed regardless of human hands by rotating the solar power generation unit 111 around a part of the rotation center according to the desert temperature (in other words, by generating a moment). . Further, by using the impact force (in other words, impulse), dust can be removed more effectively than simply swinging the solar power generation unit 111.
次に実施例２について説明する。実施例２では実施例１と異なる部分について説明する。図１０は本実施例を説明する図である。本実施例は脚１００に第１のバイメタル１０００を配置し、太陽発電ユニット１１１に第２のバイメタル１００２を配置する。第１のバイメタル１０００には突起１００１が形成されている。突起１００１には傾斜面１００３が形成されている。
Next, Example 2 will be described. In the second embodiment, parts different from the first embodiment will be described. FIG. 10 is a diagram for explaining this embodiment. In this embodiment, the first bimetal 1000 is disposed on the leg 100, and the second bimetal 1002 is disposed on the solar power generation unit 111. A protrusion 1001 is formed on the first bimetal 1000. An inclined surface 1003 is formed on the protrusion 1001.
図１０の状態を所定の温度T0での初期状態とする。図１１のよう砂漠の気温がT1（＜T0）にとなった場合、第２のバイメタル１００２は矢印１００４の方向に湾曲する。湾曲した第２のバイメタル１００２は傾斜面１００４によって移動する。その結果、図１２に示すように太陽発電ユニット１１１は矢印１００４の方向に移動する。太陽発電ユニット１１１の位置は突起１００１によって保持される。その後、砂漠の気温がT2(>T1)となると、図１３に示すように第１のバイメタル１０００は矢印１００５の方向へ湾曲する。その結果、太陽発電ユニット１１１の保持は解除され、太陽発電ユニット１１１は実施例１と同様に矢印１００６の向きに移動し、図１４に示すように板１０４に衝突する。
The state shown in FIG. 10 is assumed to be an initial state at a predetermined temperature T 0 . When the desert air temperature reaches T 1 (<T 0 ) as shown in FIG. 11, the second bimetal 1002 curves in the direction of the arrow 1004. The curved second bimetal 1002 moves by the inclined surface 1004. As a result, the solar power generation unit 111 moves in the direction of the arrow 1004 as shown in FIG. The position of the solar power generation unit 111 is held by the protrusion 1001. Thereafter, when the desert temperature reaches T 2 (> T 1 ), the first bimetal 1000 is bent in the direction of the arrow 1005 as shown in FIG. As a result, the holding of the solar power generation unit 111 is released, the solar power generation unit 111 moves in the direction of the arrow 1006 as in the first embodiment, and collides with the plate 104 as shown in FIG.
以上、本発明の実施例について説明したが、本発明は実施例に限定されない。例えば、図１５に示すように太陽光発電システムはフレーム１１０を用いず、フレーム１０８、１０９によって太陽発電アレイ１０７の端部を保持する構成しても良い。図１５の場合、脚１００と脚１０１との距離を規定するフレーム１００７によって、脚１００と脚１０１とを接続することが望ましい。
Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments. For example, as shown in FIG. 15, the solar power generation system may be configured to hold the end of the solar power generation array 107 by the frames 108 and 109 without using the frame 110. In the case of FIG. 15, it is desirable to connect the leg 100 and the leg 101 by a frame 1007 that defines the distance between the leg 100 and the leg 101.
さらに、塵埃を除去する機構は本実施例の内容に限定されない。温度（例えば、太陽光発電システムが設置される場所の温度）に応じて塵埃を除去する思想に基づくものは本明細書の開示の範囲内である。さらに、板１０４の形状も本実施例の内容に限定されない。衝撃力（その他の表現としては力積）によって塵埃を除去する思想に基づくものは本明細書の開示の範囲内である。

Those based on the idea of removing dust according to the temperature (for example, the temperature of the place where the photovoltaic power generation system is installed) are within the scope of the disclosure of this specification. Further, the shape of the plate 104 is not limited to the contents of this embodiment. It is within the scope of the disclosure of the present specification that is based on the idea of removing dust by impact force (in other words, impulse).
