Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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. 1-12, the present invention provides a technical solution: the utility model provides a detachable simple and easy double-deck grid, includes preceding grid 1 and back grid 2, and preceding grid 1 and back grid 2 are all pegged graft in grid ditch 3, and the net has been put to the equipartition on preceding grid 1 and the back grid 2, and the net straggly on preceding grid and the back grid arranges, forms the grid that the double-deck straggly distributes. The double-layer grid net is distributed in a staggered manner, and if the water inlet impurities are large, single-layer interception is adopted. The quality of the inlet water is less in impurity, and double-layer interception is adopted. Through two layers of matching and combination, different water inlet impacts are matched.

The grille ditch 3 is internally provided with a grille groove 4 matched with the front grille 1 and the rear grille 2, the tops of the front grille 1 and the rear grille 2 are both provided with a hanger 5, the hanger 5 is connected with a lifting bar 6, the middle parts of the front grille 1 and the rear grille 2 are both provided with a plurality of reinforcing ribs 7, the top of the front grille 1 is provided with a rod sleeve 8, a door blocking rod 9 is arranged in the rod sleeve 8 in a penetrating way, the bottom of the front grille 1 is detachably connected with a slag groove 10, both sides of the reinforcing ribs 7 in the middle part of the front grille 1 are both sleeved with a torsion spring shaft 11, the torsion spring shaft 11 is matched with a grille door 12, the bottom of the grille door 12 is provided with a plurality of stop lugs 13, the front grille 1, the rear grille 2 and the grille door 12 are both provided with grille nets 14 (grids), the bottom of the rear grille 2 is provided with an angle steel frame 15, the fixed interval of angle steel in the angle steel frame of both sides is 800mm, and the graticule mesh aperture of preceding grid 1 and back grid 2 is 10.

The reinforcing ribs 7 on the front grating 1 and the rear grating 2 are equal in number, two grating doors 12 are arranged on the front grating 1, the grating doors 12 are in running fit with the reinforcing ribs 7 through torsion spring shafts 11, the stop lugs 13 are matched with the reinforcing ribs 7, and the depth of the slag groove 10 is preferably 0.2-0.25 times of the height of the grating doors 12.

The working principle is as follows: when the detachable simple double-layer grating is used, the front grating 1 and the rear grating 2 carry out double-layer interception treatment on sewage passing through the grating channel 3, the front grating 1 and the rear grating 2 are both inserted into the grating groove 4 on the grating channel 3, the front grating 1 or the rear grating 2 is placed or taken out through the lifting tabs 6, when a single grating needs to be cleaned, the front grating 1 or the rear grating 2 needing to be cleaned can be lifted out of the grating channel 3 through the lifting tabs 6 to be cleaned, when one layer of grating is taken out, one layer of grating is still left in the grating channel 3 to continue sewage interception, the grating nets 14 on the front grating 1 and the rear grating 2 are distributed in a staggered mode, if the inflow impurities are large, single-layer interception can be adopted according to the requirement, when the inflow water quality impurities are small, double-layer interception can be adopted according to the requirement, and the mode of the combination of the two layers of gratings can be adopted, different water inflow impacts are matched, the grille door 12 on the front grille 1 can be locked through the shutter rod 9, when the shutter rod 9 is inserted, the shutter rod 9 blocks the grille door 12 to prevent the grille door 12 from opening, the using effect of the front grille 1 and the rear grille 2 is the same at the moment, when the shutter rod 9 is pulled out, the grille door 12 loses the limiting effect of the shutter rod 9, when sewage water flow impacts greatly and impurities in water are large, the large impurities can overcome the elasticity of the torsion spring shaft 11 to push the grille door 12 open when impacting on the grille door 12, the large impurities can fall into the slag groove 10 at the bottom of the rear side of the front grille 1, the design can prevent the large impurities from damaging the front grille 1 to buffer the impact force of the large impurities, the service life of the device is prolonged, after the large impurities pass through the grille door 12, the slag groove 10 can reset under the resilience force of the torsion spring shaft 11, and the arrangement of the slag groove 10 also enables the impurities between the front grille 1 and the rear grille 2 to be easily cleaned, when the front grating 1 is lifted, the slag groove 10 can be lifted and detached together for cleaning.
