Background technology
Hydraulic engineering is the general name of the every engineering construction built to control, utilize and protect the water resources and environment on earth's surface and underground.Hydraulic engineering is eliminate water damage and develop the engineering that water resource is built, and is divided into flood control works, farmland water conservancy works, hydraulic power project, navigation channel and port engineering, water supply and drainage system, environmental bydraulic engineering engineering, sea-beach reclamation engineering etc. by its service object.The hydraulic engineering that can simultaneously service for the plurality of target such as flood control, water supply, irrigation, generating, is called comprehensive utilization hydraulic engineering.Hydraulic engineering needs to build dam, dike, spillway, sluice, water inlet, channel, cross the different types of hydraulic structures such as mortise, log chute, fish pass, to realize its target.
Currently for farmland water conservancy works, it is usually and adopts the mode building tall and big barrage to obtain high water level to irrigate, this mode is in the good effect of a lot of local acquirement, but some areas are limited by landform, it is impossible to build tall and big barrage, cause water conservancy irrigation difficulty, add the amount of labour.For above-mentioned present situation, prior art proposes use aqueduct to solve above-mentioned technical problem, as China Patent No. " 201320295742.2 " discloses a kind of hydraulic engineering pipeline on November 13rd, 2013, its technical scheme is that described pipeline includes heavy caliber aqueduct and conduit, it is characterized in that the water inlet end of described heavy caliber aqueduct is provided with a defecator, a described defecator includes being with female filtering cover, described filtering cover is provided with a drainage screen, described filtering cover is connected with described heavy caliber aqueduct threaded engagement, it is additionally provided with secondary filter net near water side in described heavy caliber aqueduct, described conduit is provided with flow control valve and switch valve.Although the pipeline in this patent can stop dirt in diversion process, but in actual application, however it remains following defect: one is that a drainage screen is easily blocked, and cleaning after blocking and change complex procedures；Two is the caliber caliber more than conduit of aqueduct, causes that water yield is less, and diversion is inefficient；Three is the direct impact filtration net of dirt, it is easy to cause drainage screen to damage.
Utility model content
The purpose of this utility model is in that to solve the above-mentioned problems in the prior art, it is provided that a kind of hydraulic engineering defecator, and this utility model one is able to avoid dirt directly to impact filter screen, reduces the damage probability of filter screen；Two are able to reduce the blocking probability of filter screen；Three are able to quickly clear up dirt, reach the purpose of fast filtering.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of hydraulic engineering defecator, it is characterized in that: include water inlet pipe, outlet pipe, filter ball, cylindrical filter screen and the blow-off pipe with valve, described filter ball includes the upper shell and the lower house that are fixed together, the upper end closed of described cylindrical filter screen, lower end is connected to the middle part of lower house, described water inlet pipe is fixedly connected on upper shell, one end of described outlet pipe is positioned at outside filter ball, the other end stretches in cylindrical filter screen from upper shell, described blow-off pipe is connected on lower house, and blow-off pipe is correspondingly arranged at below cylindrical filter screen.
Described cylindrical filter screen includes outer net and Intranet, and the filter opening aperture of described Intranet is less than the filter opening aperture of outer net.
Described cylindrical filter screen is connected on lower house by four springs, and one end of spring is connected in cylindrical filter screen, and the other end is connected on lower house.
Being provided with groove on described lower house, the lower end of described cylindrical filter screen is positioned at groove.
The middle part of described cylindrical filter screen is provided with filter plate, and described outlet pipe is positioned at above filter plate.
Employing the utility model has the advantage of:
One, in this utility model, water inlet pipe is fixing with filter ball to be connected, the volume making water inlet pipe water outlet increases suddenly, current can be cushioned, this structure not only contributes to reduce the current impact to cylindrical filter screen, also helps the probability reducing dirt entrance cylindrical filter screen in current and minimizing dirt is attached in cylindrical filter screen and blocks the probability of cylindrical filter screen.It addition, when the dirt in filter ball is more, can promptly be cleaned out the dirt in filter ball by the blow-off pipe with valve；And when the dirt in cylindrical filter screen is more, only lower house need to be separated with upper shell, and rock lower house and can get rid of the dirt in cylindrical filter screen.There is the advantage that cleaning speed is fast and filter efficiency is high.
Two, in this utility model, the structure of two-layer cylindrical filter screen is set, is conducive to improving the filter ball filter effect to dirt.
Three, in this utility model, the structure that cylindrical filter screen is connected with lower house by four springs so that people can use bigger power to rock cylindrical filter screen without causing that filter screen shifts, when the dirt cleared up in cylindrical filter screen, better effects if.
Four, in this utility model, by being arranged on the groove on lower house, it is possible to cylindrical filter screen is positioned, it is prevented that it shifts under the impact of current.
Five, in this utility model, the dirt below filter plate can be reduced in cylindrical filter screen by filter plate and enter the probability of outlet pipe, be conducive to improving filter effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Figure is labeled as: 1, water inlet pipe, 2, outlet pipe, 3, cylindrical filter screen, 4, blow-off pipe, 5, upper shell, 6, lower house, 7, spring, 8, filter plate.
