The specific embodiment
Referring to Fig. 1-6 is the utility model drain cover and modular construction schematic diagram thereof, it comprises grate frame 7, grate face frame 8, grate plate 9 and postpones shutter, wherein grate frame 7 is the construction built-in fitting, be positioned at the bottom of drain cover, grate face frame 8 is the completion installed part, be installed on the top of grate frame 7, the foldable grate plate 9 of polylith is arranged side by side in grate face frame 8, hide whole grate face frame 8 internal drainage parts, grate face frame 8 both sides are provided with the delay shutter that is connected with every block of foldable grate plate 9, and postponing shutter is the deceleration device that slows down grate plate reversal rate.Grate plate 9 horizontal positioned during no ponding, isolated internal and external environment; When liquid stream is flowed through the grate face, by the pressure of liquid self, open the rotation grate plate 9 on the grate face frame, open the passage between the external world and the sewer, liquid stream is flowed among the sewer smoothly, flow is bigger, and the amplitude that rotation grate plate 9 is opened is just big more, and flow velocity is fast more.Otherwise, along with the minimizing of flow quantity, it also reduces the pressure that rotates grate plate 9 thereupon, rotates grate plate 9 and closes gradually until resetting, close the passage between the external world and the sewer, go round and begin again, need not any extrinsic motive and the energy, under the effect that postpones shutter, can be after being subjected to certain pressure, slowly open again in the certain hour and rotate grate plate 9, leave the reaction time of people's abundance for, the generation of avoiding above-mentioned object to drop, river bend pin, step on sky etc.
The parts concrete structure of drain cover, link position concern as follows:
Every grate plate 9 cross sections are wedge shape, two ends are provided with a hole 10, be fixed in by axle in the axis hole of grate face frame 8 inwall both sides, one connects one grate face frame 8 is arranged and expires, axle one end is fixed in 9 holes 10 of grate plate, the other end passes the axis hole of grate face frame 8 inwalls, the grate plate 9 wherein the tip of the axis of a side is provided with contact block 16, also can contact block 16 all be set two ends, contact block 16 is used for being connected with the delay shutter, give axle with the force transmission that postpones shutter, drive grate plate 9 and do corresponding motion, the contact block 16 general fixed forms that adopt perpendicular to axle.
The embodiment one that postpones shutter:
Referring to Fig. 5, gear postpones shutter by the torsion spring 14 that is fixed on the pinion 13, middle gear 12 with pinion 13 engagements, form with the gear wheel 11 and the shell 15 of middle gear 12 engagements, above-mentioned all parts are fixed in the shell 15, torsion spring 14 1 ends are fixed on the pinion 13, the other end stretches out shell 15 and is connected with described contact block 16, its workflow is: when liquid stream is flowed through the grate face, the pressure of liquid self, give to press and rotate grate plate 9, driven gear postpones large size gear 11 rotations in the shutter 5, drives medium size gear 12 simultaneously successively, small size gear 13 rotates in the mode that rotating speed successively decreases.Do to slow down when turning to small size gear 13 at rotary power, the torsion spring 14 that drives between fixing and small size gear 13 and the shell 15 is done afterburning rotation, form elastic force, the grate plate turned over for 9 times and opened this moment, liquid stream is flowed among the sewer smoothly, and flow is bigger, and the pressure of liquid self is just bigger, the amplitude of rotating 9 unlatchings of grate plate is just big more, and flow velocity is fast more.Otherwise, minimizing along with flow quantity, its to rotate grate plate 9 and with it the gear of interlock postpone shutter 5 pressure and reduce simultaneously, the torsion spring 14 of this moment will discharge previously stored elastic force energy, rotation grate plate 9 be resetted close, close the passage between the external world and the sewer, after the grate face is in closed condition, with place or road be on same plane substantially, finish a workflow, reciprocation cycle need not any extrinsic motive and the energy.
The embodiment two that postpones shutter:
The operating principle that piston postpones shutter 6 is: by the qualification to hydraulic oil 23 specific dischargies, implement the control to the unit interval, to reach in the example, to the delay unlatching of rotation grate plate 9 and the job requirement of quick closedown.Piston postpones shutter 6 and is provided with piston rod 24, be provided with hydraulic oil 23 in the cylinder, one end of described piston rod 24 is provided with piston rod 17, the other end is provided with bottom 25, described piston rod 17 1 ends connect described contact block 16, piston 18 in the other end and the piston rod 24 is connected, 25 of piston 18 and bottoms are provided with return spring 22, described piston 18 is provided with two unidirectional pod apertures 21 of different directions, this unidirectional pod apertures 21 is to be made of the steel ball and the spring that are stuck in the wedged hole, and wherein the aperture of the big liquid flow hole 20 of inside water conservancy diversion is greater than the aperture of the little liquid flow hole 19 of outside water conservancy diversion.Its workflow is: when liquid stream is flowed through the grate face, the pressure of liquid self, give to press and rotate grate plate 9, interlock contact block 16 is exerted pressure to piston 18 by the piston rod 17 that is in contact with it the formula connection, piston 18 behind the pressurized forces the hydraulic oil 23 in the piston rod 24, push the hoodle 21 that is positioned at little liquid flow hole 19 open, hydraulic oil 23 through the bottom of little liquid flow hole 19 from piston rod 24, is pressed into the top release, makes and rotate slowly unlatching of grate plate 9, open the passage between the external world and the sewer, liquid stream is flowed among the sewer smoothly, and flow is bigger, and the pressure of liquid self is just bigger, the amplitude of rotating 9 unlatchings of grate plate is just big more, and flow velocity is fast more.Otherwise, minimizing along with flow quantity, it is to rotating the grate plate 9 and the contact block 16 of interlock with it, piston rod 17 to 18 applied pressures of piston reduce simultaneously, the big elastic spring 22 that is between piston 18 bottoms and the bottom 25 will be oppressed piston 18 rollbacks, behind hydraulic oil 23 pressurizeds on piston rod 24 tops, push the hoodle 21 that is positioned at big liquid flow hole 20 open, with the top of the big liquid flow hole 20 of hydraulic oil 23 warps from piston rod 24, be back to the bottom of piston rod 24 fast, not having the back piston 18 of pressure until the outside returns fully, rotation grate plate 9 is resetted close, close the passage between the external world and the sewer, after the grate face is in closed condition, with place or road be on same plane substantially, finish a workflow, reciprocation cycle need not any extrinsic motive and the energy.
Note drain cover in order to warn passerby, we are provided with the caution enamelled coating on grate plate 9 surfaces, polylith grate plate 9 enamelled coating when the grate face is in closed condition constitutes a complete pattern, we can drain cover according to the difference of place to use, be designed to different shape and pattern, simultaneously can be in its surface engraving, be depicted as colorful picture or write words and expressions, not only can be used as warning function, can also be as the billboard media and the carrier of promote products.
