本考案は、廃水処理のための沈澱池に設備され
ているトラフ内に藻が発生、付着するのを防止す
る遮光装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a shading device that prevents algae from growing and adhering to a trough installed in a sedimentation pond for wastewater treatment.
従来の一般的廃水処理システムは、幾度も沈澱
池等を経て汚泥や有害物質が取り除かれた廃水を
最終沈澱池に導入して、該最終沈澱池に敷設され
ているトラフの溢流板(ノツチ板ともいう)を越

ラフ表面に藻類が発生・付着して排水の流れを阻
害するので、藻類の除去ないし掃除を頻繁に行な
わねばならないという欠点を有していた。 Conventional general wastewater treatment systems introduce wastewater from which sludge and harmful substances have been removed after passing through settling tanks several times into a final settling tank. Only the supernatant of the treated wastewater that overflows the drain (also known as a board) is discharged into rivers, etc. However, in the troughs used in this type of final settling basin, algae grows and adheres to the overflow plate surface and the trough surface, obstructing the flow of wastewater, so algae must be removed or cleaned frequently. It had the disadvantage that it did not.
このような藻類の発生・付着等を防止するため
本考案者らは、日光が当たらない所に藻が発生し

付着するのを抑えるという問題は解決されている
ものの、トラフ1内に堆積した汚泥等を掃除する
際における上方遮光板2の開閉作業が煩わしいも
のとなる問題を含んでいた。 In order to prevent the growth and adhesion of such algae, the present inventors focused on the fact that algae are difficult to grow in areas that are not exposed to sunlight, and installed an upper light shielding plate 2 that can be opened and closed above the trough 1 of the sedimentation basin. proposed a shading device for a trough, which is equipped with a side shading plate 3 that prevents sunlight from obliquely from the side (Utility Model Registration No. 1431807; Utility Model Registration No. 1431807;
(See Publication No. 33666). However, this light shielding device prevents algae from growing on the inner surface of the trough 1 and the overflow plate 4.
Although the problem of suppressing adhesion has been solved, there is still the problem that opening and closing the upper light shielding plate 2 when cleaning sludge and the like accumulated in the trough 1 becomes troublesome.

う。 That is, in the conventional light shielding device, the upper light shielding plate 2 attached to the pedestal 6 is opened and closed by the operator using the handle 5, so that the upper light shielding plate 2 is opened and closed by twisting and manufacturing problems. In consideration of operational problems and the fact that the trough 1 is over ten meters long, the upper light shielding plate 2 is divided into appropriate lengths and constructed independently of each other. Therefore, when a worker descends into the trough 1 for cleaning, the upper light shielding plate 2
It is a hassle to have to open and close each one one by one.
また、上方遮光板2を手頃な長さに分割した従
来の遮光装置においては、連なる上方遮光板2の

着するのを防止し得ない問題を有する。 In addition, in the conventional shading device in which the upper shading plate 2 is divided into convenient lengths, the sun shines through between the continuous upper shading plates 2, making it impossible to prevent algae from growing and adhering to some parts. There are no problems.
本考案は、上述の問題を解消しようとするもの
で、屋根即ち遮光板を手軽にトラフ全域において
同時に開閉し得るトラフ用遮光装置を提供するこ
とを目的とする。 The present invention aims to solve the above-mentioned problems, and aims to provide a trough light shielding device that can easily open and close the roof, that is, the light shielding plate over the entire trough at the same time.

している。 In order to achieve this purpose, the present invention divides the roof that covers the entire trough from sunlight in the longitudinal direction of the trough and attaches each to two rotating shafts installed parallel to the trough, and also controls the rotation of one of the rotating shafts. The rotary shafts are connected to each other by a rotation transmitting means that transmits reverse rotation to the other rotary shaft, and by rotating either of the rotary shafts, the roofs are rotated in opposite directions to open and close the trough simultaneously in the entire area. I have to.

ためのものである。 The above-mentioned light-shielding roof 7 has a convex cross-sectional shape, blocks sunlight from above the trough and from an angle, and covers the inner surface of the trough and the overflow plate 4 from sunlight. this roof 7
As shown in FIGS. 2 and 3, the trough 1 is divided into two parts along the longitudinal central axis of the trough 1, and the trough 1 directly below is divided into two parts by swinging toward and away from each other in the width direction of the trough 1. Open and close. A cushioning material 10 made of an elastic material such as rubber or plastic is attached to the dividing surface 9 of the roof 7 extending in the longitudinal direction of the trough. This cushioning material 10 crushes and cushions each other when the roof 7 is closed, and also prevents a gap from forming at the dividing surface 9 portion. Therefore, in this roof 7, even if the dividing planes 9 are not formed into parallel planes with a predetermined gap due to low manufacturing precision or twisting or bending of the product (roof) itself, the dividing planes 9 No sunlight leaks into the trough from this part. Further, in this embodiment, the roof 7 is integrally molded with the reinforcing ribs 10 using glass fiber reinforced plastic (hereinafter referred to as FRP), but it is also possible to mold it using other metals or plastics. It is. However, from the viewpoint of lightness and rigidity, it is desirable to use FRP. The reinforcing ribs 11 are for preventing deformation of the curved portion 7a that blocks sunlight entering the trough 1 from diagonally above.

成る。 The above-mentioned roof 7 is fixed to rotary shafts 13, 13' supported by bearings 12 on a pedestal 8 so as to be swingable. Two rotating shafts 13 and 13' that support the roof 7 are installed parallel to each other along the trough 1. Both ends of these rotating shafts 13, 13' are connected by a rotation transmitting means 15, and are provided so that they rotate in opposite directions at the same time by the same angle. In this embodiment, since the rotating shafts 13 and 13' are long, they are formed by connecting a plurality of shafts with a coupling 14.

を左右で異にすることも可能である。 The rotation transmitting means 15 transmits the rotation of one rotary shaft 13 to the other rotary shaft 13' as reverse rotation, and for example, in the case of this embodiment, two levers 16, 16' and one connection A link mechanism consisting of a link 17 is employed. In this link mechanism, one lever 16' of levers 16 and 16' each pin-connected to both ends of a connecting link 17 is fixed to the rotating shaft 13' in a hanging state, and the other lever 16 is fixed to the rotating shaft 13 in an upright position. , the two rotating shafts 13, 13' are connected so as to interlock in rotational motion. Therefore, one rotating shaft 13 is
When it is rotated by an operating lever 18 attached to one end, the other rotating shaft 13' rotates in the opposite direction, so that the roof 7 supported by these rotating shafts 13, 13' can be opened and closed. In the case of the rotation transmission means 15 using this link mechanism, as in this embodiment, the lever 1
It is possible to set the lengths of 6 and 16' to be equal to equalize the degree of opening of the left and right roofs 7, that is, the angle of rotation, or it is also possible to make the degree of opening of the left and right roofs 7 different by making the lever lengths different. It is.

In the case of a V-belt, pulleys may be attached to both rotating shafts 13 and 13', and the V-belt may be hung crosswise around these pulleys. In the case of chains and ropes with ends, they are installed by spanning them in an S-shape (diagonally) between sprockets or wheels on both shafts. In addition, when gears are used, the gears on both shafts are directly engaged with each other, or an even number of idle gears are interposed therebetween.
尚、前述の回転軸13を回転させる手段として

藻類が発生・付着することがない。 As described above, in the trough shading device of the present invention, the roof that covers the entire trough is divided into two in the longitudinal direction of the trough and each is attached to two rotating shafts that rotate in opposite directions. By means of an operation, for example a lever operation, the roof can be opened or closed to expose the entire trough. In addition, since the entire trough is divided into two parts by a dividing plane extending in the longitudinal direction of the trough, and the roof is opened and closed by rotating the roof in opposite directions, it is possible to open and close the roof by rotating the roof in opposite directions. Unlike other devices, there is no need to provide a gap in the split surface area, so sunlight will not leak through this area and algae will not grow or adhere to it.
