Abstract

Изобретение относитс к насосостроению и может быть использовано при строительстве и реконструкции насосных станций. Цель изобретени - повышение надежности работы водозаборного устройства, обеспечение устойчивого вертикального перемещени приемного конфузора при заборе воды из открытых водоисточников с сильным течением и обеспечение забора воды с необходимого уровн . Внутри цилиндрической обечайки 3 вертикально и соосно размещена всасывающа труба 1 с конфузорным участком 2. Обечайка 3 установлена на дне водоисточника. Конфузор 4 охватывает обечайку 3, св зан с поплавками (П) 5 и снабжен направл ющими 6 его вертикального перемещени . Устройство дл предотвращени воронкообразовани выполнено в виде направл ющих лопаток 7, закрепленных на П 5 и по периметру верхней части конфузора 4 с образованием сливных окон. Сваи 9 закреплены на дне водоисточника. Направл ющие 6 выполнены на сва х 9. Жесткие т ги соединены с П 5 и подвижно св заны с направл ющими 6. Отбойные щиты 11 установлены на П 5 с возможностью вертикального перемещени . За счет установки обечайки 3 в насосе не попадают донные наносы, а П 5 и щитов 11 - плавающие тела. 2 з.п. ф-лы, 2 ил.The invention relates to pump engineering and can be used in the construction and reconstruction of pumping stations. The purpose of the invention is to increase the reliability of the water intake device, to ensure a stable vertical movement of the receiving confuser when drawing water from open water sources with a strong current and to ensure water withdrawal from the required level. Inside the cylindrical shell 3 vertically and coaxially placed the suction pipe 1 with confused section 2. The shell 3 is installed at the bottom of the water source. The confuser 4 encloses the shell 3, is connected with the floats (P) 5 and is provided with guides 6 for its vertical movement. The device for preventing the funnel formation is made in the form of guide vanes 7 fixed on the П 5 and along the perimeter of the upper part of the confuser 4 with the formation of drain windows. Piles 9 are fixed at the bottom of the water source. The guides 6 are made on their sleeves 9. The rigid rods are connected to the P 5 and are movably connected to the guides 6. The fender boards 11 are mounted on the P 5 with the possibility of vertical movement. Due to the installation of the shell 3 in the pump does not get bottom sediments, and P 5 and shields 11 - floating bodies. 2 hp f-ly, 2 ill.

Claims

Claim

1. A water intake device containing a suction pipe with a confuser section vertically and coaxially placed inside a cylindrical shell mounted at the bottom of the water source, a movable receiving confuser covering a cylindrical shell connected to the smelter and provided with guides for its vertical movement and a device for preventing eronogenesis, characterized the fact that, in order to increase reliability by preventing the ingress of floating bodies into the suction pipe of the pump, a device for prevent funnel formation. is made in the form of guide vanes mounted on the float and around the perimeter of the upper part of the confuser with the formation of drain windows.

2. The device according to π. 1, characterized in that, in order to ensure stable vertical movement of the torpedo confuser during the intake of water from open water sources with a strong current, it is equipped with piles fixed to the bottom of the water source and rigid rods, while the guides of vertical movement of the confuser are made on piles, and rods connected to the float and movably connected to the guides.

3. The device according to p. I, characterized in that, in order to ensure the intake of water from the required level, it is equipped with baffle plates mounted on the float with the possibility of vertical movement.
