Description

I Изобретение относитс к рыбозаградительным устройствам, позвол ющим осуществл ть водозабор из водоемов , имеющих рыбохоз йственное значение .I The invention relates to fish barrier devices that allow water to be drawn from water bodies of commercial importance.

Известно рыбозащитное устройство дл водозаборной всасывающей камеры, размещенной на дне водоема, содержащее сетчатый барабан, установленный на входе всасывающей камеры, с воз- мЬжностью поворота вокруг Шарнира в вертикальной плоскости, промывное и поплавково-балластное приспособлени Ci ., A fish protection device for an intake suction chamber located at the bottom of a reservoir is known, which contains a mesh drum installed at the entrance of the suction chamber, with the possibility of turning around the Hinge in a vertical plane, washing and float-ballast devices Ci.,

Недостатком известного рыбозащитного устройства вл етс мала эффективность очистки его от наносов.A disadvantage of the known fish protection device is the low efficiency of cleaning it from sediment.

Цель изобретени - повышение эффективности очистки от наносов. . The purpose of the invention is to increase the efficiency of sediment removal. .

Это достигаетс тем, что на дне водоема выполнена каменна постель, на которой размещены барабан с промывным и поплавково-балластным приспособлени ми , шарнир выполнен С This is achieved by the fact that at the bottom of the reservoir a stone bed is made on which a drum with washing and float-ballast devices is placed, the hinge is made C

;фланцем, п|эичем устройство снабжено гидромонитором с клапаном, взаимодействующий с фланцем шарнира.; flange, n | eichem device is equipped with a water jet with a valve, interacting with the flange of the hinge.

На фиг.1 изображено рь озащитное устройство с водозаборной всасывающей камерой, общий вид; на фиг.2 то же, со стороны водоприема.Figure 1 shows the pry defensive device with intake suction chamber, General view; figure 2 is the same, from the side of the intake.

Устройство состоит из сетчатого барабана 1, жестко прикрепленного Л балластной емкости 2, котора свободно установлена на каменной постели 3 водозаборной всасывающей камеры k. В балластную емкость вмонтированы промывное приспособление, состо щее из эжекторных насадок S,The device consists of a net drum 1, rigidly attached L of the ballast tank 2, which is freely mounted on the stone bed 3 of the suction chamber k. A washing device is installed in the ballast tank; it consists of ejector nozzles S,

и воздухопровод 6. Сетчатый барабан при помощи патрубка 7 и вертикального шарнира 8 соединен с водозаборной всасывающей камерой 4. На вертикальном шарнире 8 выполнено флан- and air duct 6. The mesh drum is connected by a pipe 7 and a vertical hinge 8 to the intake suction chamber 4. On the vertical hinge 8, a flange is made

Claims

The 26 connection 9a on the suction intake chamber k is fitted with a hydraulic monitor 10 with a water supply pipe 11 and a valve 12. The device works as follows. If it is necessary to clean the mesh drum 1 from sediments into the ballast tank 2, compressed air is supplied through the air duct 6, which displaces water from the ballast tank 2 through the ejector nozzles 5. Expiring 1cc from ejector nozzles 5 strong water jets wash off part of the sediment from the mesh drum 1. As water flows out of the ballast tank 2, water-air mixture begins to be pulled out through the ejector nozzles 5, which tears off the sediment from the mesh drum 1 of difficult-to-remove sediments. After it has been displaced, water is drained from the ballast tank 2, through ejector nozzles 5, and compressed air flows out, which finally cleans the mesh drum from sediments, transporting them to the surface of the reservoir and dispersing it to the sides from the fish protection device. As water is displaced from the ballast tank 2, the fish protection device becomes positive. buoyancy and floats. The fish protection device is limited by the free running of the vertical hinge 8 with a flange joint E, which presses valve 12 and actuates the jet monitor 10 connected to the water supply pipe 11. A powerful jet of water flowing through the jetting nozzle 10, washes away all sediment from the stone bed. At the end of the complete cleaning of the mesh drum 1 from sediment,: the supply of compressed air to the ballast-g 4 capacity tank 2 is stopped. Through the ejector nozzles 5, water begins to flow into the ballast tank 2, the fish protection device gradually loses its positive buoyancy and gently sits on the stone bed 3. As the fish protection device is lowered, the flange connection 9 of the vertical hinge 8 releases the valve 12, which, under pressure from the water into the water supply tube 11, sits down in place and closes the access of water to the jet monitor 10. Claims of the invention A fish protection device for a water intake suction chamber located at the bottom of a reservoir containing a mesh bar A ban mounted at the entrance of the suction chamber can be rotated around a hinge in a vertical plane, washing and float-ballast devices, characterized in that, in order to increase the efficiency of cleaning from sediments, a stone bed is made at the bottom of the reservoir, on which a drum with washing and float-ballast devices, the hinge is made with a flange, and the device is equipped with a hydromonitor with a valve that interacts with the flange of the hinge.
