To provide a dirt removal device capable of easily checking the communication state between a sewage storage tank and a sewage inlet of a railway vehicle.SOLUTION: A disclosed dirt removal device includes: a box-shaped sewage inlet with an opening in the top; a lid to cover the opening of the sewage inlet; a tubular dirt removal arm for introducing dirt removed from a sewage storage tank of a railway vehicle into the sewage inlet that is attached to the lid; a suction hose that is attached to the tip of the dirt removal arm and is capable of being connected to a discharge outlet of the sewage storage tank of the railway vehicle; and a valve for checking the water supply attached to the middle of the dirt removal arm outside the sewage inlet. The valve for checking the water supply includes: a shaft body; an opening/closing lid rotatable on the shaft body; and a balance weight rotated together with the opening/closing lid on the shaft body, which is attached to the opening/closing lid. The opening/closing lid is configured to change the position of the balance weight as the flow rate of wastewater in the dirt removal arm increases.SELECTED DRAWING: Figure 3
【課題】鉄道車両の汚物タンクと汚水枡との連通状態の確認を容易に行うことができる汚物抜き取り装置を提供する。【解決手段】本発明に係る汚物抜き取り装置は、上面に開口部を有する箱形形状の汚水枡と、汚水枡の開口部を覆う蓋と、蓋に取り付けられ、汚水枡に鉄道車両の汚物タンクから抜き取られた汚物を導入するための管状の汚物抜き取りアームと、汚物抜き取りアームの先端部に取り付けられ、鉄道車両の汚物タンクの排出口に接続可能なサクションホースと、汚水枡の外部において、汚物抜き取りアームの途中に取り付けられる給水確認弁とを備える。給水確認弁は、軸体と、軸体を中心として回転可能な開閉蓋と、開閉蓋に取り付けられ、軸体を中心として開閉蓋と一体的に回転可能なバランスウェイトとを含み。開閉蓋は、汚物抜き取りアーム内の汚水の流量の増加に伴って、バランスウェイトの位置を変化させる。【選択図】図3
