Цель изобретения - повышение эффективности промывки.The purpose of the invention is to increase the washing efficiency.

Поставленная цель достигается тем, что устройство снабжено отжимным приспособлением, выполненным в виде шарнирно закрепленных на оси спаренных колес пары роликов, установленных с зазором для ввода гибкого трубопровода, причем нижний ролик выполнен съемным.This goal is achieved by the fact that the device is equipped with a squeezing device made in the form of a pair of rollers pivotally mounted on the axis of the paired wheels mounted with a gap for introducing a flexible pipe, and the lower roller is removable.

На фиг.1 изображено устройство, общий вид; на фиг.2 - то же, вид сверху, на фиг.З - разрез А-А на фиг.2.Figure 1 shows the device, a General view; figure 2 is the same, a top view, figure.Z - section aa in figure 2.

Устройство для промывки гибких трубопроводов состоит из спаренных, колей 1, соединенных между собой через ось 2, на которой через кронштейн 3 шарнирно закреплены ролики 4 и 5 с определенным зазором 6 для ввода трубопровода 7. Устройство снабжено ручкой 8. При этом нижний ролик 5 выполнен съемным. Диаметр колес 1 выбирается в зависимости от рельефа трассы трубопровода 7 и его° диаметра.A device for washing flexible pipelines consists of paired, tracks 1 connected to each other through an axis 2, on which rollers 4 and 5 are pivotally mounted through a bracket 3 with a certain clearance 6 for introducing a pipeline 7. The device is equipped with a handle 8. The lower roller 5 is made removable. The diameter of the wheels 1 is selected depending on the relief of the route of the pipeline 7 and its ° diameter.

Устройство работает следующим образом.The device operates as follows.

После окончания полива и прекращения подачи воды, устройство подключается к началу трубопровода 7. Для этого ролик 5 снимается, и поливной трубопровод 7 вводится между роликами 4 и 5. Нижний ролик закрепляется с определенным зазором 6 на прежнее место. В трубопровод 7 подается определенный расход воды, который достаточен для свободного передвижения устройства по направлению трассы трубопровода 7. В месте прохода через ролики 4 и 5 поперечное сечение потока сужается, а скорость движения воды здесь повышается в несколько раз. При этом выше сужения образуется напор воды, который увеличивается до определенного предела и двигает устройство по направлению . течения воды. Осаждающиеся наносы при взаимодействии с потоком промываются, постепенно перемещаются на концевой участок трубопровода и сбрасываются в сбросную сеть.After the end of irrigation and the cessation of water supply, the device is connected to the beginning of the pipeline 7. To do this, the roller 5 is removed, and the irrigation pipe 7 is inserted between the rollers 4 and 5. The lower roller is fixed with a certain clearance 6 to its former place. A certain flow rate of water is supplied to the pipeline 7, which is sufficient for the free movement of the device in the direction of the route of the pipeline 7. At the passage through the rollers 4 and 5, the cross section of the stream narrows, and the speed of water here increases several times. In this case, a water pressure forms above the narrowing, which increases to a certain limit and moves the device in the direction. water currents. The precipitated sediments, when interacting with the flow, are washed, gradually moved to the end section of the pipeline, and discharged into the discharge network.

Для качественной промывки трубопровода поливальщик наблюдает за ходом промывки, управляя устройством при помощи вспомогательной ручки 8. Для лучшего передвижения устройства все его элементы выполняются из лег кого материала. Скорость передвижения устройства по длине трубопровода 7 зависит от количества отложившихся наносов и регулируется подачей воды в шланг. При большом количестве наносов возможна последовательная работа нескольких устройств на одном шланге.For high-quality flushing of the pipeline, the irrigator monitors the flushing process, controlling the device with the auxiliary handle 8. For better movement of the device, all its elements are made of lightweight material. The speed of movement of the device along the length of the pipeline 7 depends on the amount of deposited sediment and is regulated by the flow of water into the hose. With a large number of sediments, several devices can work sequentially on one hose.

Claims

The invention relates to agriculture and can be used when flushing flexible pipe pumps. Under production conditions, flushing of flexible pipelines from sediment deposition of sediments is carried out manually due to the creation of large washing out rates of water movement and partially due to the creation of water hammer 1. However, this method is very time consuming and the duration of the irrigation hose comes to 6 hours. There is also known a method for flushing flexible pipelines, carried out by a device, including a pressure source connected to pipeline 2. However, the use of this device does not provide high quality washing. The purpose of the invention is to increase the efficiency of washing. The goal is achieved by the fact that the device is provided with a squeezing device made in the form of a pair of rollers mounted on the axis of the paired wheels, which are installed with a gap to enter the flexible pipe, the lower roller being made removable. Figure 1 shows the device, a general view; figure 2 is the same, top view, fig.Z - section aa in figure 2. A device for flushing flexible pipelines consists of paired, oscillations 1 interconnected through an axis 2, on which rollers 4 and 5 are hinged through bracket 3 with a defined gap 6 for insertion of pipe 7. The device is equipped with a handle 8. The lower roller 5 is complete removable. The diameter of the wheels 1 is selected depending on the relief of the route of the pipeline 7 and its diameter. The device works as follows. After the end of irrigation and the water supply is stopped, the device is connected to the beginning of the pipeline 7. To do this, roller 5 is removed, and irrigation pipe 7 is inserted between rollers 4 and 5. The lower roller is fixed with a certain gap 6 to its original place. Pipe 7 is supplied with a certain water flow, which is sufficient for free movement of the device in the direction of the route of pipe 7. At the point of passage through rollers 4 and 5, the flow cross section is narrowed, and the speed of water movement here increases several times. In this case, a water head is formed above the constriction, which increases to a certain limit and moves the device in the direction of water flow. The sedimented sediments of the contact with the flow are washed gradually moving to the end section of the pipeline and discharged into the discharge network. For a good flushing of the pipeline, the drifter observes the flushing progress, controlling the device with the aid of an auxiliary handle 8. For the best movement of the device, all its elements are made of lightweight material. The speed of movement of the device along the length of the pipeline 7 depends on the amount of deposited sediment and is regulated by the flow of water into the hose. With a large amount of sediment it is possible to work consistently with several devices on the same hose. Claim 1. A device for flushing flexible pipes, including a pressure source connected to a pipeline, characterized in that, in order to increase the efficiency of washing, the device is equipped with a release device made in the form of a pair of rollers mounted on an axis of paired wheels of rollers mounted with a clearance for input flex. 2. The device pop. 1, differs from the fact that the lower roller is made removable. Sources of information taken into account in the examination 1. Sheinkin G.Yu. and others.
