Technical Field

The utility model relates to a sewage treatment technical field especially relates to an prevent stifled sewage grid.

Background

The sewage generally contains more impurity, generally utilizes the different filter media of various aperture sizes before carrying out chemical treatment, adopts the mode of separation to get rid of the impurity of aquatic outside, lets the great impurity of volume unable pass through, carries out subsequent chemical treatment mode again to obtain clean water.

However, in the use process of the traditional grating, under the impact action of water flow, some large impurities are easily adsorbed on the surface of the grating, so that the grating is blocked, and the normal passing of the water flow is further influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem in the background art and providing an anti-blocking sewage grid.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an anti-blocking sewage grid comprises a fixed plate and a grid body embedded in the middle of the fixed plate, wherein two connecting pipes are fixed on the upper side wall of the fixed plate, a lifting plate is inserted at the lower end of each connecting pipe, a telescopic spring is fixed between each lifting plate and the inner top wall of each connecting pipe, a floating block is fixed at the lower end of each lifting plate, openings communicated with the inner parts of the two connecting pipes are formed in the sides, close to each other, of the two connecting pipes, gears are installed in the two openings, saw teeth meshed with the gears are arranged on one side, close to the gears, of the lifting plate, cams are mounted on the outer wall of the fixed plate, connecting ropes are fixed between the middle parts of the two gears and the middle parts of the cams, the outside of grid body is equipped with the horizontal plate, the outer wall of cam contacts with the last lateral wall of horizontal plate, the lower lateral wall of horizontal plate is fixed with the pole of scraping of a plurality of vertical settings.

Preferably, two abutting rods are fixed on the upper side wall of the horizontal plate, the upper ends of the two abutting rods penetrate through the upper side wall of the fixing plate, and a return spring located between the upper side wall of the fixing plate and the horizontal plate is sleeved on the outer wall of each abutting rod.

Preferably, two of said floating blocks are located outside the grid body.

Preferably, a plurality of L-shaped protrusions are integrally formed on one side, close to the grating body, of each scraping rod, and the ends of the protrusions are turned inwards.

Compared with the prior art, this prevent stifled sewage grid's advantage lies in:

1. when the large impurities on the surface of the grating body excessively influence the normal passing of water flow, water is accumulated, the height of the water surface is increased, the floating block is driven to move upwards, the gears are driven to rotate through the meshing of the sawteeth and the gears, the two connecting ropes are wound, the cam is driven to rotate, and the horizontal plate is extruded to move through the cam;

2. when the longer end of the cam rotates away from the horizontal plate, the horizontal plate moves back under the action of the elastic force of the return spring, so that the up-and-down movement of the scraping rod is realized;

to sum up, the utility model discloses a drive the cam through the rising of the surface of water and rotate the reciprocating that realizes scraping the pole when grid body surface impurity piles up, strike off impurity, do not guarantee the normal use of grid with the help of external power.

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

Referring to fig. 1-2, an anti-blocking sewage grid, including fixed plate 1 and inlay the grid body 2 of establishing at fixed plate 1 middle part, the last lateral wall of fixed plate 1 is fixed with two connecting pipes 3, the lower extreme of every connecting pipe 3 is all inserted and is equipped with lifter plate 4, be fixed with expanding spring 14 between the interior roof of every lifter plate 4 and connecting pipe 3, the lower extreme of every lifter plate 4 all is fixed with floats piece 5, two float pieces 5 are located the outside of grid body 2, when rivers normally flow, rivers height is lower, float piece 5 this moment and be located lower position.

Openings communicated with the inner parts of the two connecting pipes 3 are respectively formed in one sides, close to the two connecting pipes, of the two connecting pipes, gears 11 are respectively installed in the two openings, sawteeth meshed with the gears 11 are arranged on one sides, close to the gears 11, of the lifting plates 4, cams 10 are installed on the outer wall of the fixing plate 1, connecting ropes 12 are respectively fixed between the middle parts of the two gears 11 and the middle parts of the cams 10, horizontal plates 6 are arranged on the outer sides of the grid bodies 2, the outer walls of the cams 10 are in contact with the upper side walls of the horizontal plates 6, when large impurities on the surfaces of the grid bodies 2 excessively affect normal passing of water flow, water is accumulated, the water surface height is increased, the floating blocks 5 are driven to move upwards, the gears 11 are driven to rotate through meshing of the sawteeth and the gears 11, the two connecting ropes 12 are wound, the cams 10 are driven to rotate, and when the longer ends of the cams 10 are, the lower lateral wall of horizontal plate 6 is fixed with the pole 9 of scraping of a plurality of vertical settings, and every one side integrated into one piece of scraping pole 9 and being close to grid body 2 has a plurality of archs 13 that are the setting of L type, and the tip of arch 13 is toward the inboard roll-over, and the setting is rolled over and is avoided the tip acutely, keeps away scratch grid body 2, scrapes off the large-scale impurity in surface of grid body 2 through the removal of scraping pole 9.

The lateral wall is fixed with two and supports pole 7 on the horizontal plate 6, and two upper ends that support pole 7 run through the lateral wall setting on the fixed plate 1, support the outer wall of pole 7 and go up the cover and be located fixed plate 1 and go up the reset spring 8 between lateral wall and the horizontal plate 6, when the longer end of cam 10 changes from horizontal plate 6, horizontal plate 6 moves back under reset spring 8's spring action, and then realizes scraping reciprocating of pole 9.

Further, unless otherwise specifically stated or limited, the above-described fixed connection is to be understood in a broad sense, and may be, for example, welded, glued, or integrally formed as is conventional in the art.

Now, the operation principle of the present invention is explained as follows:

when rivers normally flow, the rivers height is lower, this moment, it is in lower position to float piece 5, when the normal of the too much influence rivers of large-scale impurity on grid body 2 surfaces passes through, water piles up, the surface of water height risees, it up moves to drive floats piece 5, meshing drive gear 11 through sawtooth and gear 11 rotates, carry out the rolling of two connection ropes 12, and then drive cam 10 and rotate, horizontal plate 6 down moves when the longer end of cam 10 contacts with horizontal plate 6, when the longer end of cam 10 changes from horizontal plate 6, horizontal plate 6 moves back under reset spring 8's elasticity effect, and then realize reciprocating of scraping bar 9, strike off the impurity on grid body 2 surfaces through arch 13, resume the flow of rivers.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
