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.

Embodiment one, refer to fig. 1, 2, in the embodiment of the utility model provides an anti-warping escape canal double-edged fine-toothed comb, include: the grate comprises a grate body 1, a filter screen 2 and a fixed block 3, wherein the fixed block 3 is arranged at two sides of a drainage ditch 4, a fixed shaft 31 is arranged below the fixed block 3, the barb structure 32 inclines upwards along the axial direction of the fixed shaft 31, a threaded hole is arranged above the fixed block 3, bolt mounting holes 14 are arranged at two sides of the grate body 1, the grate body 1 is connected with the fixed block 3 through bolts 15, when the grate is arranged on the drainage ditch 4, the fixed shaft 31 is firstly inserted into the concrete which is not solidified and just poured at two sides of the drainage ditch 4, after the concrete is solidified, the fixed shaft 31 and the drainage ditch 4 form an integrated structure, the fixing function is strengthened, the barb structure 32 has the anti-falling effect, the concrete part of the support body 1 is prevented from falling for a long time, the grate body 1 is prevented from being lifted, and the grate body 1 and the fixed block 3 are locked through the bolts 15, therefore, when the grate body 1 needs to be taken away to maintain and clean the drainage ditch 4, the bolts 15 are unscrewed, and the grate body 1 is taken down.

The perforated strainer body 1 is provided with a plurality of water seepage holes 11, the water seepage holes 11 are uniformly distributed, the cross section of each water seepage hole 11 is in an inverted trapezoid shape, the cross section of each water seepage hole 11 is gradually increased from bottom to top, so that articles such as walking stick bicycle wheels and the like can be conveniently taken out when being clamped in the water seepage holes 11, a filter mesh screen 2 is arranged between the perforated strainer body 1 and a fixed block 3, the middle of the filter mesh screen 2 is concave, through holes are formed in the filter mesh screen 2 at positions corresponding to bolt mounting holes 14 of the perforated strainer body 1, bolts penetrate through the perforated strainer body 1 and the filter mesh screen 2 and are fixed on the fixed block 3, the bolt mounting holes 14 in the perforated strainer body 1 are countersunk holes, so that bolt heads are embedded in the perforated strainer body 1 and cannot obstruct passersby a passerby to walk, the filter mesh screen 2 is distributed above a drainage ditch 4, and when articles fall from the water seepage holes 11, the filter mesh, when wanting to get back article, unscrew the bolt, take off grate body 1, just can follow filter screen 2 and get back article, filter screen 2 can also play coarse filtration's effect to the rainwater, can prevent effectively that large-scale impurity from falling into escape canal 4, leads to drainage pipe to block up.

Be equipped with slotted hole 21 on the 2 lateral walls of filter screen, when displacement is great, the filter screen shines 2 upward debris and gathers more influence drainage, and slotted hole 21 on the lateral wall can act as the wash port and use, improves drainage performance, because the slotted hole sets up at 2 sides of filter screen, consequently can not hinder the interception function of filter screen 2.

In the second embodiment, as shown in fig. 2 and 3, the difference from the first embodiment is that the grate body 1 in the second embodiment is divided into a grate plate with bolt mounting holes 14 and a grate plate without bolt mounting holes, the two ends of the grate plate are respectively provided with a boss structure 12 and a sink structure 13 which are matched with each other, when a plurality of grate bodies 1 are mutually spliced, the grate body 1 in the middle can adopt a grate without the bolt mounting holes 14, the installation of the fixing block 3 is also omitted, the grate plates on the two sides of the grate body 1 are installed in the fixing block mode, and the grate in the middle is fixed by matching the bosses and the sink grooves.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
