Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: an underground filtering device for a sponge city comprises an outer frame 1, wherein a fixing plate 2 is fixedly connected to the outer side surface of the outer frame 1, the device can be fixed above a rainwater port through the fixing plate 2, a rain grate 4 is movably connected to the inner side wall of the outer frame 1 through a supporting plate 3 arranged on the inner side wall of the outer frame, the rain grate 4 can filter some sundries with large volume out of rainwater, the supporting plate 3 is a rectangular frame, the supporting plate 3 can support the rain grate 4 and enable a filtering box 6 to pass through the inner side wall of the outer frame 1, the outer frame 1 is movably connected with a filtering box 6 through four supporting rods 5 fixedly connected to the lower side surface of the outer frame, each supporting rod 5 comprises an L-shaped vertical rod and a bottom plate fixedly connected to the lower end of the vertical rod, the bottom plate can support the filtering box 6, the vertical rod can limit the position of the filtering box 6, and a filtering cover 7 is fixedly connected to the inner side, the filter mantle 7 can filter out the comparatively little rubbish of volume (say so that wastepaper, broken leaves etc.) in the rainwater, the filter mantle 7 comprises two swash plates 701 and two riser 702, two equal fixed connection of riser 702 are on the inside downside of rose box 6, and the one end of two swash plates 701 respectively with two riser 702 fixed connection, other end interconnect, all be equipped with a plurality of through holes on swash plate 701 and the riser 702, the downside of rose box 6 and the below that is located filter mantle 7 are opened and are had through-hole 9, and the jam that prevents that two swash plates 701 and two riser 702 can be fine sets up, and debris can be along the swash plate 701 landing after being filtered out by filter mantle 7, then fall between riser 702 and the lateral wall of rose box 6, and water can directly drop the inside that advances the sewer through swash plate 701 and through-hole 9.

Specifically, the through hole 9 is rotatably connected with a filter plate 8 through a rotary groove 10 arranged on one side wall of the through hole, the mesh number of filter holes on the filter plate 8 is larger than that of the filter cover 7, debris such as pebble, silt and the like in the rainwater can be filtered, the number of filter holes on the two side surfaces of the filter box 6 and the two sides of the filter cover 7 is the same as that of the filter plates 8, the silt can be filtered, the filtering efficiency can be increased, a notch 11 is arranged on one side surface of the filtering plate 8 far away from the rotary groove 10, the notch 11 is movably clamped with a clamping plate 13, the clamping plate 13 is rotatably connected to the lower side surface of the filter box 6 through a rotating shaft 12, the width of the rotating clamping plate 13 is the same as that of the notch 11, the clamping plate 13 can be rotated to control whether to be clamped with the notch 11 or not, therefore, whether the filter plate 8 is turned away or not can be realized, and sundries filtered out from the filter plate 8 can be cleaned up after the filter plate is turned away.

Specifically, the upper side of the clamping plate 13 is fixedly connected with the protrusion 15, the lower side of the filter plate 8 is provided with the bayonet 14 corresponding to the protrusion, and the bayonet 14 and the protrusion 15 are arranged to prevent the clamping plate 13 from rotating randomly, so that the filter plate 8 is automatically rotated and cannot work.

particularly, all be equipped with spring 16 between the downside of rose box 6 and four bearing rod 5, spring 16's one end and bearing rod 5 fixed connection, the other end and rose box 6 fixed connection, if torrential rain weather appears, the inside untimely condition of drainage probably appears because of the hole is less in rose box 6, rose box 6 inside water that this moment filter box 6 can more and more make also more and more heavy, rose box 6 will overcome spring 16's elasticity downstream like this, thereby it lets the rainwater process to make to produce the gap between rose box 6 and the rain grate 4, thereby be applicable to this kind of special environment demand, municipal drainage system all has corresponding staff to regularly to patrol and examine the maintenance, if discover here inlet for stom water offal and receive the influence, can open rain grate 4 and clear up.

Specifically, spring 16's the outside just is located fixedly connected with protective housing 17 on the support rod 5, the downside of rose box 6 is opened and is had the slot 18 that corresponds with it, and protective housing 17 can protect spring 16, prevents that spring 16 from leading to rustting because long-time and water contact to reduce its life.

Specifically, a plurality of reinforcing ribs 19 are arranged between the outer side surface of the outer frame 1 and the fixing plate 2, and the arrangement of the reinforcing ribs 19 can enable the fixing plate 2 and the outer frame 1 to be connected more stably.

The working principle is as follows: when the rain grate is used, the outer frame 1 is firstly installed at a designated rainwater inlet position through the fixing plate 2, then the filter box 6 is placed among the four supporting rods 5, and finally the rain grate 4 is covered, rainwater enters the filter box 6 through the rain grate 4 in the rainy day, then flows into the interior of a sewer through the filter cover 7 and the filter plate 8, and filters out some sundries with larger volume when passing through the rain grate 4, the filter cover 7 filters out some sundries with smaller volume, and the filter plate 8 filters out stone silt and the like; the filter box 6 is cleaned as required to prevent blockage, the filter box 6 can be taken out only by moving the rain grate 4 away during cleaning, sundries filtered out by the filter cover 7 can be poured out after the sundries are taken out, then the filter plate 8 can be rotated away after the clamping plate 13 is rotated, the sundries filtered out by the filter plate 8 can be cleaned at the moment, and the filter box 6 can be put back after the cleaning is finished.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
