Description

Self-cleaning Storm-water inlet

The utility model relates to a kind of inlet for stom water of removing mud voluntarily and having anti-theft feature, is specially adapted to the drainage of road.

The applicant has applied for that to Patent Office of the People's Republic of China name is called antitheft grate inlet for stom water patent on August 6th, 92, and its number of patent application is 92216707.9.The inlet for stom water that this patent documentation is described is the mud sump of depositing that is fixed with grate by top, be located at the catch-basin of depositing mud sump one side and communicating with it, the manhole cover base of band latch is bearing in the lock case of catch-basin both sides and is contained in the lockset that constitutes away from the lock box of depositing on mud sump one side and pin well lid on catch-basin and by being contained in the locked groove below the well lid.The grate of this antitheft grate inlet for stom water is fixed on to be deposited on the mud sump, and well lid pins by lockset again.Therefore, grate and lockset can not stolen, and well lid can not removed by the people easily yet, so entail dangers to vehicle and pedestrian's safety not.But the mud of depositing in the mud sump also will be by manually going cleaning, and this can increase a large amount of hand labors.

The purpose of this utility model is to provide a kind of inlet for stom water, and making is having on the basis of theftproof performance, can reach to remove the mud of depositing in the mud sump voluntarily, thereby alleviate workman's work.

The utility model auto purification type inlet for stom water is deposited mud sump, on depositing mud sump, the iron grate is fixed on and deposits above the mud sump by the holdfast back-grouting, catch-basin is positioned at deposits mud sump one side, the well lid of seat on catch-basin, the one end has latch can insert the grate lower end, its corresponding end is bearing in the lock case of catch-basin both sides and is contained in catch-basin and pin well lid away from the lockset of depositing on mud sump one side that lock box constituted by being contained in the locked groove below the well lid.Its feature is: depositing mud sump near the water-filling pond that the kerb side has the upper and lower through hole of process to be attached thereto, a plurality of through holes are arranged between water-filling pond and the kerb, the water-filling pond is to link to each other by the control pipeline with catch-basin; The control funnel that a band filter screen is arranged below the control pipe outlet at catch-basin place, on near the rainwater borehole wall of depositing the mud sump side, hang a gate by hinge, this gate just blocks the breach of depositing between mud sump and the catch-basin, one be cross wishbone lever by hinged support on the two side of catch-basin, an end rectangular with it withstands on the gate, and it is hinged with the control funnel that the other end is fork-shaped.

Can also a swash plate be set on the mud sump depositing, be divided into upper and lower two parts depositing mud sump, the mud, the rubbish that are leaked down by grate is deposited on top.

The utility model auto purification type inlet for stom water is work like this:

When fine, rubbish that is leaked down by grate and mud are deposited in to be deposited in the mud sump or deposits on the swash plate that the concrete of mud sump makes, rain or other reasons flow into deposit mud sump water not for a long time, can drain by the inflow catch-basin of the gap between the gate and the rainwater borehole wall and from underground pipeline, the water yield for a long time, water flows into the water-filling pond by the through hole of depositing between mud sump and the water-filling pond, when the water level in water-filling pond is raised to above the control pipeline between water-filling pond and the catch-basin, water flows into the control funnel through this pipeline, when the water level of control funnel is increased to certain altitude, wishbone lever tilts, an end that withstands on gate rises, releasing is to the constraint of gate, and gate is opened under the pressure of depositing mud sump side water, water in depositing mud sump or the mud on its swash plate pour catch-basin and drain from underground pipeline, when rainwater after a little while, the water that flows in the control funnel goes into not pay, and wishbone lever recovers horizontal level, makes closing gate; If do not rain for a long time, rubbish and mud pile with deposits mud sump, and when raining, rainwater can flow into the water-filling pond from the through hole between kerb and the water-filling pond, then pour the control funnel by the control pipeline, thereby open the sluices, rainwater and rubbish and the mud deposited in the mud sump flow into underground pipeline together, and the rainwater well lid need not opened generally speaking, in the time will making regular check on maintenance, the available dedicated key is opened the lockset on the well lid, removes well lid, dredging underground pipeline or maintenance or replacing component.

The utility model advantage compared with prior art is: it can clear up the mud of depositing in the mud sump voluntarily, does not need manually to open lid again, draws out rubbish and mud from deposit mud sump.Therefore can save workman's work greatly.
