Description
【０００１】[0001]
本考案は、冷水塔に関するものである。 The present invention relates to a cold water tower.
【０００２】[0002]
図４及び図５は従来の冷水塔の一例を示すもので、建屋１の天板２中央部に突 設したファンスタック３内のファン４を回転駆動することにより、前記建屋１内 の空気をファンスタック３から上方に排気して建屋１側部に設けたルーバ５から 外気６を取り込み、且つ温水供給管７を介して導いた温水８を建屋１内上部のス プレイノズル９から散水し、該散水した温水８を充填物１０中を滴下させる間に 前記外気６との直接接触により熱交換させて冷却し、該冷却した水８’を建屋１ 内下部の冷水タンク１１に回収するようにしてある。 FIG. 4 and FIG. 5 show an example of a conventional cold water tower, in which the air in the building 1 is moved by rotationally driving a fan 4 in a fan stack 3 projecting in the center of a top plate 2 of the building 1. The exhaust air is exhausted upward from the fan stack 3, the outside air 6 is taken in from the louver 5 provided on the side of the building 1, and the hot water 8 guided through the hot water supply pipe 7 is sprayed from the spray nozzle 9 in the upper part of the building 1, During the dropping of the sprinkled warm water 8 into the filler 10, the sprinkled warm water 8 is directly contacted with the outside air 6 to exchange heat for cooling, and the cooled water 8'is collected in a cold water tank 11 in the lower part of the building 1. There is.
【０００３】 前記ファン４は、ファンスタック３内下側に架設したビーム１２に取り付けら れた減速機１３のトルク伝達軸１４に軸支されており、前記減速機１３には、天 板２上に配置したモータ１６の駆動軸１５が接続されていて、前記モータ１６の 駆動トルクが前記減速機１３のギヤ機構により減速されてファン４に伝達される ようになっている。The fan 4 is rotatably supported by a torque transmission shaft 14 of a speed reducer 13 mounted on a beam 12 installed on the lower side of the fan stack 3, and the speed reducer 13 is mounted on the top plate 2. Is connected to the drive shaft 15 of the motor 16, and the drive torque of the motor 16 is reduced by the gear mechanism of the speed reducer 13 and transmitted to the fan 4.
【０００４】 前記減速機１３内には、ギヤ歯の摩耗防止の為に潤滑油１７が充填されている が、該潤滑油１７は前記トルク伝達軸１４に設けられた図示しない撥ね掛け板に よって掻き回される為、前記減速機１３内に潤滑油１７のガス１８が発生する。Lubricating oil 17 is filled in the speed reducer 13 in order to prevent wear of gear teeth. The lubricating oil 17 is provided by a splash plate (not shown) provided on the torque transmission shaft 14. The gas 18 of the lubricating oil 17 is generated in the speed reducer 13 because it is stirred.
【０００５】 その為、前記減速機１３には、ファンスタック３を貫通して一端を外部に開口 した排気管１９の他端が接続されており、減速機１３内に発生したガス１８が大 気中に排出されるようになっている。Therefore, the speed reducer 13 is connected to the other end of the exhaust pipe 19 which penetrates the fan stack 3 and has one end open to the outside, and the gas 18 generated in the speed reducer 13 is large. It is designed to be discharged inside.
【０００６】[0006]
【考案が解決しようとする課題】 しかしながら、積雪量が多い地域では、前記排気管１９の排気口２０が天板２ 上につもった雪２１に埋まって閉塞してしまうことがあり、このような場合には 、減速機１３内に発生したガス１８が排出されなくなって前記減速機１３内の圧 力が上昇し、この圧力上昇によりオイルシール部から潤滑油１７が漏出して減速 機１３のギヤ機構が焼きつく虞れがあった。However, in an area with a large amount of snow, the exhaust port 20 of the exhaust pipe 19 may be buried in the snow 21 on the top plate 2 and may be blocked. In this case, the gas 18 generated in the speed reducer 13 is no longer discharged, and the pressure inside the speed reducer 13 rises. Due to this pressure increase, the lubricating oil 17 leaks out from the oil seal portion and the gear of the speed reducer 13 is leaked. There was a risk that the mechanism would burn.
【０００７】 また、天板２の積雪に埋まらないよう前記排気管１９を図６に示す如くファン スタック３外で上方に屈曲させ、排気口２０を天板２から十分に離間した位置に 開口させることも考えられるが、このように排気管１９の排気口２０を天板２か ら離間させると、吹雪等の際に前記排気口２０が乱流状態の風雪に晒され易くな り、側方から（場合によっては斜め下方から）吹き付ける雪２１により排気口２ ０が詰まる虞れがある。Further, the exhaust pipe 19 is bent upward outside the fan stack 3 as shown in FIG. 6 so as not to be buried in the snow on the top plate 2, and the exhaust port 20 is opened at a position sufficiently separated from the top plate 2. However, if the exhaust port 20 of the exhaust pipe 19 is separated from the top plate 2 in this way, the exhaust port 20 is likely to be exposed to turbulent wind and snow during a snowstorm or the like. There is a possibility that the exhaust port 20 may be blocked by the snow 21 blown from above (or obliquely from below in some cases).
【０００８】 本考案は、上述の実情に鑑みてなしたもので、積雪量の多い地域でも減速機用 排気管の排気口の閉塞を確実に防止し得る冷水塔を提供することを目的としてい る。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cold water tower that can reliably prevent the exhaust port of a reduction gear exhaust pipe from being blocked even in an area with a large amount of snow. It

本考案は、ファンの減速機に接続されてファンスタック外部まで延びる排気管 の排気口を、建屋の天板上に立設され且つ上部に開口部を有する筒状壁で包囲し 、該筒状壁を前記開口部が開放された状態で包囲し且つ下部に大気に連通する開 口部を備えた防雪カバーを前記筒状壁の上部に設けたことを特徴とする冷水塔に 係るものである。 According to the present invention, the exhaust port of an exhaust pipe connected to a fan speed reducer and extending to the outside of the fan stack is surrounded by a cylindrical wall which is erected on the top plate of a building and has an opening at the top. The present invention relates to a cold water tower, comprising a snow cover which surrounds a wall in a state where the opening is opened and which has a lower part having an opening communicating with the atmosphere at the upper part of the tubular wall. .
【００１０】[0010]
従って本考案では、建屋の天板上に雪がつもっても、排気管の排気口は筒状壁 及び防雪カバーにより包囲されているので閉塞することがなく、減速機内で発生 したガスは排気管を通して筒状壁内に排気され、更に該筒状壁上部の開口部を抜 けて防雪カバー下部の開口部から大気中に排気される。 Therefore, in the present invention, even if there is snow on the roof of the building, the exhaust port of the exhaust pipe is not blocked because it is surrounded by the cylindrical wall and the snow cover, and the gas generated in the reducer passes through the exhaust pipe. The air is exhausted into the tubular wall, and the air is exhausted into the atmosphere through the opening in the lower part of the snow cover through the opening in the upper part of the tubular wall.
【００１１】[0011]
以下本考案の実施例を図面を参照しつつ説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【００１２】 図１及び図２は本考案の一実施例を示すもので、図中図４及び図５と同一の符 号を付した部分は同一物を表わしている。1 and 2 show an embodiment of the present invention, in which the same reference numerals as those in FIGS. 4 and 5 represent the same parts.
【００１３】 前述した図４及び図５の冷水塔と略同様に構成した冷水塔２２において、ファ ン４の減速機１３に接続されてファンスタック３外部まで延びる排気管１９の排 気口２０を、建屋１の天板２上に立設され且つ上部に複数の開口部２３を有する 筒状壁２４で包囲する。In a cold water tower 22 configured substantially similar to the cold water towers of FIGS. 4 and 5 described above, an exhaust port 20 of an exhaust pipe 19 connected to the speed reducer 13 of the fan 4 and extending to the outside of the fan stack 3 is provided. , Is erected on the top plate 2 of the building 1 and is surrounded by a cylindrical wall 24 having a plurality of openings 23 in the upper part.
【００１４】 前記筒状壁２４の軸心部には、該筒状壁２４の底部から上部を貫通して上方に 延び且つ前記上部から突出した上側部分にネジ部２５を形成した支持シャフト２ ６を立設し、該支持シャフト２６のネジ部２５には、前記開口部２３が開放され た状態で前記筒状壁２４を包囲する下部開口の防雪カバー２７を螺着し、該螺着 部をロックナット２８により固定する。At the axial center portion of the tubular wall 24, a support shaft 26 is formed in which a threaded portion 25 is formed in an upper portion that extends upward from the bottom of the tubular wall 24 through the upper portion and projects from the upper portion. And a snow cover 27 of a lower opening surrounding the tubular wall 24 is screwed to the threaded portion 25 of the support shaft 26 with the opening 23 open, and the threaded portion is attached. It is fixed by the lock nut 28.
【００１５】 尚、本実施例においては、防雪カバー２７下端と筒状壁２４外周との間が前記 防雪カバー２７下部の開口部２９となる。In this embodiment, an opening 29 at the bottom of the snow cover 27 is located between the lower end of the snow cover 27 and the outer circumference of the cylindrical wall 24.
【００１６】 而して、防雪カバー２７の下端が予想される積雪高さＸより高くなるよう支持 シャフト２６のネジ部２５に対する前記防雪カバー２７の螺着位置を調整し、ロ ックナット２８により固定しておけば、建屋１の天板２上に雪２１がつもっても 、排気管１９の排気口２０は筒状壁２４及び防雪カバー２７により包囲されてい るので閉塞することがなく、減速機１３内で発生したガス１８は排気管１９を通 して筒状壁２４内に排気され、更に該筒状壁２４上部の開口部２３を抜けて防雪 カバー２７下部の開口部２９から大気中に排気される。Then, the screwing position of the snow cover 27 with respect to the threaded portion 25 of the supporting shaft 26 is adjusted so that the lower end of the snow cover 27 is higher than the expected snow height X, and the snow nut 27 is fixed with the lock nut 28. If the snow 21 is kept on the top plate 2 of the building 1, since the exhaust port 20 of the exhaust pipe 19 is surrounded by the cylindrical wall 24 and the snow cover 27, it will not be blocked and the speed reducer 13 will be closed. The gas 18 generated inside is exhausted into the cylindrical wall 24 through the exhaust pipe 19, passes through the opening 23 in the upper part of the cylindrical wall 24, and is exhausted to the atmosphere from the opening 29 in the lower part of the snow cover 27. To be done.
【００１７】 従って上記実施例によれば、積雪量の多い地域でも減速機１３用排気管１９の 排気口２０の閉塞を確実に防止することができ、減速機１３内に発生したガス１ ８を良好に排出することができるので、減速機１３内の圧力上昇による潤滑油１ ７の漏出、及びこれに起因する減速機１３のギヤ機構の焼きつきを確実に防止す ることができる。Therefore, according to the above-described embodiment, it is possible to reliably prevent the exhaust port 20 of the exhaust pipe 19 for the speed reducer 13 from being blocked even in an area with a large amount of snow, and to prevent the gas 18 generated in the speed reducer 13. Since the oil can be satisfactorily discharged, it is possible to reliably prevent the leakage of the lubricating oil 17 due to the pressure increase in the speed reducer 13 and the seizure of the gear mechanism of the speed reducer 13 due to the leakage.
【００１８】 図３は本考案の他の実施例を示すもので、前述した図１及び図２の実施例での 支持シャフト２６による支持手段に換えて、防雪カバー２７を筒状壁２４の上側 外周に刻設したネジ部３０に直接螺着させて支持するよう構成した例であり、図 示では筒状壁２４の上面全てを開口部２３として開口し且つ防雪カバー２７の下 部に適宜数の開口部２９を穿設した構造としてある。FIG. 3 shows another embodiment of the present invention. Instead of the supporting means by the support shaft 26 in the embodiment of FIGS. 1 and 2, the snow cover 27 is provided above the cylindrical wall 24. This is an example in which the screw portion 30 engraved on the outer periphery is directly screwed and supported, and in the figure, the entire upper surface of the cylindrical wall 24 is opened as an opening portion 23, and an appropriate number is provided under the snow cover 27. The opening 29 is provided as a structure.
【００１９】 尚、本考案の冷水塔は、上述の実施例にのみ限定されるものではなく、本考案 の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。The cold water tower of the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the scope of the present invention.
