A rainwater source control and sewage interception device for water conservancy projects and its use method

technical field

The invention relates to the field of rain and flood source control and sewage interception, in particular to a rain and flood source control and sewage interception device for water conservancy projects and a use method thereof.

Background technique

Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. The development of water conservancy in water conservancy projects needs to be realized through a certain number of hydraulic structures. These hydraulic structures play the roles of water storage, water delivery, and diversion. Water storage, water delivery, and diversion of hydraulic structures are carried out for a long time. In rainy weather, it is easy to form rain floods. A large amount of sundries and impurities will be carried in the flow of rain and floods, and sundries and impurities will be brought into the water along ditches and pipelines. In the water body where the industrial structure acts, it will not only pollute the water body, but also affect the operation of the hydraulic structure. Therefore, in order to prevent and control pollution, it is necessary to control the source of the rainwater discharged from the ditches and pipelines, and to remove the larger debris and sediment impurities in the rainwater.

In the patent CN109721179A, the impurities are filtered through the filter screen, and the impurities in the sewage are crushed by the crushing device. The incompletely broken impurities are easily embedded in the mesh of the filter under the impact of the water flow, and it is not convenient to discharge the impurities embedded in the mesh of the filter; Impurities will block the filter to a certain extent, which will further increase the pressure of the water flow, and will easily cause damage to the filter in long-term use; at the same time, due to the large amount of sludge in the sewage, when the large impurities are broken, the impurities will be mixed with the sludge. If they are mixed together, it will be inconvenient to deal with the filtered mixed impurities in the future, and it will be inconvenient to recover the recyclable impurities, which will not only cause waste, but also easily cause environmental pollution.

Therefore, in the existing sewage treatment, there is the problem of inconvenient discharge of the impurities embedded in the mesh of the filter screen, the problem that the filter screen is easily damaged by long-term stress, and the processing inconvenience caused by the mixing of impurities and silt after the impurities are crushed The problem. For this reason, we propose a rainwater source control sewage interception device for water conservancy projects and its application method.

Since the bottom of the water diversion rod is elastically connected to the water guide through the elastic component, under the impact of the flood and the action of the elastic component, the water diversion rod will continue to undergo elastic vibration, which can shake off the sundries on the water diversion rod and facilitate the removal of debris. Slip down on the lower end of the water distribution rod. At the same time, it can also dry the water, speed up the filtration efficiency, and use the water to take away impurities and reduce the adhesion of impurities on the water distribution rod.

Embodiment one:

Please refer to Figure 1-10, a rainwater source control and sewage interception device for water conservancy projects, including a flood diversion component, a dredging component arranged in the middle of the flood diversion component, and a sundry separation component arranged at the end of the flood diversion component, And the sewage filter component arranged under the debris separation component; this design does not need to consume electric energy, and works through the action of flood without consuming energy. It can be used in an environment where power supply is inconvenient, and saves costs.

The flood guiding component includes a water guiding channel 1, and a rolling water slope 2 fixedly arranged at the water inlet end of the water guiding channel 1, and the rolling water slope 2 is used to roll the passing rainwater. The hydraulic structures built in the water conservancy project will have outfalls such as ditches and pipelines upstream of the river channels where they are located. In rainy weather, the rainwater gathered in the ditches and pipelines will enter the river channels from the outfalls. The water inlet end of the aqueduct 1 in the device is facing the outlet of the ditch/pipe, and the rainwater is controlled for source control and sewage interception.

In this design, the rainwater is discharged from the top of the rolling water slope 2, and the flowing flood water is rotated and rolled through the rolling water slope 2, which will "absorb" the debris in the water, and the flood rolls in the middle of the aqueduct 1, making it difficult for the debris to break away. During the tumbling process of the flood, a large number of air bubbles will be produced in the water. The air bubbles will reduce the buoyancy of the debris in the water, making the debris suspended in the water. able to separate.

The dredging assembly includes an arc panel 3 fixedly arranged at the bottom inside the middle section of the aqueduct 1, a floating shaft 4 movably arranged in the middle of the inner side of the middle section of the aqueduct 1, and a plurality of plates 5 fixedly arranged on the side of the floating shaft 4. Above the flood rolling position, the arc panel 3 is located on one side of the rolling water slope 2. The arc panel 3 is used to promote the rolling of the passing rainwater, and the floating shaft 4 is acted by buoyancy to press the floating objects in the rainwater into the water. The plate 5 is driven by the water flow to drive the floating shaft 4 to rotate;

In this design, the flood flows obliquely upwards from the height of the arc panel 3 through the arc panel 3, which can promote the flood to roll over, enhance the device’s ability to roll over the flood, and ensure that the sundries in the flood flowing down the rolling water slope 2 are swept away with the water flow. Rinse into the tumble vortex to ensure all debris is rinsed away. The floating shaft 4 presses the low-density suspended debris in the water, and the plate 5 can continuously change the position of the debris and change the suspension state of the debris in the water during the process of being driven by the water flow, so that the debris will not gather, so that The tumbling water flow and air bubbles can contact the sundries in a larger area, and the sundries can be washed more completely. And in the case of dispersing the sundries, at the same time, the sundries can not be easily discharged from the bottom of the floating shaft 4, so as to achieve the effect of cleaning the sundries for a long time. The floating shaft 4 presses the suspended debris with low density into the water, and makes the suspended debris with low density submerged in water, which is beneficial to form a comprehensive flushing of the debris.

In this design, through the tumbling of the flood, the blocky silt in the water can be washed away, decomposed and dissolved in the flood, so that it will not fall into the debris separation component during the filtration stage and will not be mixed in the debris. It solves the problem of the follow-up silt adhering to the sundries, and solves the problem of the mud clogging the sundries separation components. So that the separated sundries will not be attached by silt, etc., and will not affect the subsequent cleaning of the sundries. Therefore, the device is easy to recover the substances in the sundries and to perform other treatment on the sundries. After the sundries are conveniently disposed of, the problem of discarding the sundries can be reduced, and environmental pollution can be effectively reduced.

The debris separation assembly includes a plurality of evenly spaced water dividing rods 6 arranged at one end on the water outlet of the aqueduct 1, a rotating shaft 7 movably arranged on the water outlet of the aqueduct 1, a plurality of blocking plates 8 fixedly arranged on the side of the rotating shaft 7, and The scraper 9 is fixedly arranged on the side of the blocking plate 8 away from the rotating shaft 7, and the other end of the water dividing rod 6 is elastically connected with the water guide channel 1 through an elastic component. For debris, the blocking plate 8 is an arc-shaped plate structure, and the arc-shaped plate surface is used to carry debris. The side of the scraper 9 away from the blocking plate 8 is fixed with a plurality of evenly spaced scrapers 10, and the scrapers 10 are used To scrape off the sundries in the space between a plurality of water distribution rods 6 .

In order to make the width of the filtered sundries not change, so as to prevent the bulky sundries from flowing out from the gap during the rotation of the water dividing rod 6 . The flood is discharged from the outlet end of the channel 1 with debris and rushes into the blocking plate 8, and the debris stays in the arc surface of the blocking plate 8, which can reduce the erosion, collision and damage caused by the flood and the debris in the water to the water diversion rod 6. pressure, not only avoiding the damage of the water diversion rod 6 due to excessive force, but also reducing the damage caused by water and sundries to the water diversion rod 6, and then avoiding the damage caused by the sundries blocking the gap between the water diversion rods 6 The problem of reducing the filtering effect, such benefits can improve the service life of the water diversion rod 6, and make the impact and gravity of water and sundries act more on the blocking plate 8, which will generate a greater push for the blocking plate 8 The effect of force is not only convenient to protect the blocking plate 8, but also makes the blocking plate 8 have a stronger deflection force, and the blocking plate 8 drives the scraper 9 to rotate, which also makes the ability to scrape impurities stronger. The scraping blade 10 can go deep into the filter gap, push out the debris in the gap by scraping the debris, and can remove the stubborn debris, making the impurity removal more thorough. When the blocking plate 8 rotates to the lowest point quickly, the debris rolls down from the blocking plate 8 onto the water dividing rod 6, is pushed out by the follow-up scraper 9, and finally discharged from the bottom of the water dividing rod 6. Since the bottom of the water diversion rod 6 is elastically connected to the water guide channel 1 through the elastic component, under the impact of the flood and the action of the elastic component, the water diversion rod 6 will continuously undergo elastic vibrations, which can shake off the sundries on the water diversion rod 6 , to make things convenient for the sundries to slide down at the lower end of the water-distributing rod 6.

And it can hinder the sundries, and the sundries impact on the cutting block 11 under the action of the water flow, which will generate strong vibration to the sundries, which is beneficial to remove the impurities and silt on the surface of the sundries. At the same time, it can change the shape of debris, making it easier to expose the silt on it and be decomposed by water flow.

The side wall of the water guide 1 is provided with a chute 12, and the inside of the chute 12 is movably provided with a slider 13, and the end of the floating shaft 4 is movably connected with the slider 13.

In this design, the floating shaft 4 is always floating on the water surface, so that the device can automatically adjust the overall height of the dredging assembly according to the water storage volume in the boiling water area of the water guide 1, so that the floating shaft 4 and the plate 5 can be adjusted at different depths of water. able to work. When the floating shaft 4 is at the lowest position, there is a gap between the plate 5 and the inner bottom wall of the aqueduct 1 to accommodate the passage of debris. When the flood water is insufficient, the debris will be washed away from the gap with the water flow, preventing debris from being deposited inside the aqueduct 1 .

Wherein, the debris separating assembly further includes a rotary damper 14 fixedly arranged on the outer wall of the water guide 1 , and the end of the rotating shaft 7 is fixedly connected to the movable end of the rotary damper 14 .
