Description
Technical field
The utility model relates to water conservancy construction technical field, is specifically related to a kind of reverse-stop type silting blocking device.
Background technique
The full excavation section long for channel or cut and fill section, concrete liner is adopted completely below general main canal one-level packway, for preventing underground water uplift pressure to the destruction of Concrete Lining of Canals plate, ponding hidden pipe is arranged under concrete liner plate, see Fig. 1, longitudinally all arrange two ponding hidden pipes at the bottom of Qu Po, canal, a ponding hidden pipe is arranged in lateral separation.Arrange a single slope drainage valve at longitudinal direction interval, drain valve end face and lining concrete are put down.When underground bigcatkin willow pressure exceedes channel hydraulic pressure, underground water is entered channel by single slope drainage valve by underground water, and when water crossed by channel, single slope drainage valve cuts out, and channel water does not enter underground by drain valve.
Run into rain channel ponding after Concrete Lining of Canals all completes and can reach more than 50cm; find that mud at the bottom of canal is also thicker after the drained water of channel ponding; One-way drainer at the bottom of traditional canal often by whole silting, cannot be able to be opened, and such underground water will threaten the safety of canal liner plate.
Model utility content
For the problem that One-way drainer silting at the bottom of current canal cannot effectively solve, the utility model provides a kind of reverse-stop type silting blocking device.
For achieving the above object, adopt following technological scheme: a kind of reverse-stop type silting blocking device, comprises silting blocking device cap from top to bottom, up and down cover plate successively, silting blocking device main body, lock sheet and fastener rings; Described silting blocking device main body is tubular structure, and its sidewall is provided with osculum; The upper end of silting blocking device main body is threaded connection silting blocking device cap, and lower end is threaded connection described fastener rings; Between described silting blocking device main body and silting blocking device cap, form inner chamber, described up and down cover plate can move up and down in this inner chamber, is positioned at bottom osculum when up and down cover plate falls, and is positioned at osculum top during rising.
On the downside of described up and down cover plate, be provided with guide rod, described silting blocking device main body wall be provided with pilot hole, this guide rod and pilot hole Matching installation.The outer rim of described silting blocking device cap is provided with the outward extending the brim of a hat.In described silting blocking device main body or fastener rings, movable balls can be installed.Silting blocking device osculum is located at silting blocking device side (the positive apparent direction of upper figure is osculum), the protection of the overhanging the brim of a hat is provided with above water outlet, up and down cover plate is established in inside, when underground bigcatkin willow pressure exceedes channel hydraulic pressure, will the movable balls jack-up (unlatching of check valve water cut-off device) in check valve, upwardly open after up and down cover plate in silting blocking device is stressed, water flows out from the osculum the silting blocking device overhanging the brim of a hat; When underground bigcatkin willow pressure was less than channel hydraulic pressure, the movable balls in check valve fell automatically (closedown of check valve water cut-off device), and in water cut-off device and silting blocking device, up and down cover plate is closed simultaneously, and silt particle cannot enter valve body.
Silting blocking device water outlet is located at current downstream direction, the moving direction of upper and lower cover plates is vertical with water (flow) direction, and when silting blocking device is by water impact, up and down cover plate can not be opened because of flow action, thus avoid silt particle to enter check valve inside from water outlet causing alluvial, anti-silting effective.
The utility model reverse-stop type silting blocking device replaces the common lid on check valve top, solves following technical barrier:
1. solve the technical problem of canal's moving phase check valve silting, can guarantee that check valve effectively runs, ensure canal's moving safety.
2. reverse-stop type silting blocking device is changed conveniently, and member replacing is easy, and maintenance cost is low.
3. can save the desilting expense to check valve, the normal operation of check valve can not be had influence on canel desilting.
Accompanying drawing explanation
Fig. 1 is reverse-stop type silting blocking device installment state schematic diagram;
Fig. 2 is the assembly structure schematic diagram of reverse-stop type silting blocking device.
In figure, label 1 silting blocking device cap, 2 is up and down cover plate, 3 is silting blocking device main body, and 4 is lock sheet, and 5 is fastener rings, 6 is guide rod, and 7 is guiding groove, and 8 is upper screw thread, 9 is nut, and 10 is lower screw thread, and 11 is water outlet, 12 is vertical tube, and 13 is the hidden pipe that longitudinally catchments, and 14 is sandy gravel, 15 is the hidden pipe that laterally catchments, and 16 is at the bottom of canal.
Embodiment
Embodiment: see Fig. 2, reverse-stop type silting blocking device, profile is streamlined, and height 48mm, it is made up of silting blocking device cap, up and down cover plate, silting blocking device main body, lock sheet, fastener rings, hydathode positioned inside " movable balls ".The outer rim of silting blocking device cap is provided with the outward extending the brim of a hat.
Silting blocking device main body is tubular structure, and its sidewall is provided with osculum.
The upper end of silting blocking device main body is threaded connection silting blocking device cap, and lower end is threaded connection described fastener rings; In described silting blocking device main body or fastener rings, movable balls can be installed.
Between described silting blocking device main body and silting blocking device cap, form inner chamber, up and down cover plate can move up and down in this inner chamber, is positioned at bottom osculum when up and down cover plate falls, and is positioned at osculum top during rising.
On the downside of described up and down cover plate, be provided with guide rod, described silting blocking device main body wall be provided with pilot hole, this guide rod and pilot hole Matching installation.
Silting blocking device osculum is located at silting blocking device side, the protection of the overhanging the brim of a hat is provided with above water outlet, up and down cover plate is established in inside, when underground bigcatkin willow pressure exceedes channel hydraulic pressure, will the movable balls jack-up (unlatching of check valve water cut-off device) in check valve, upwardly open after up and down cover plate in silting blocking device is stressed, water flows out from the osculum the silting blocking device overhanging the brim of a hat; When underground bigcatkin willow pressure was less than channel hydraulic pressure, the movable balls in check valve fell automatically (closedown of check valve water cut-off device), and in water cut-off device and silting blocking device, up and down cover plate is closed simultaneously, and silt particle cannot enter valve body.
Silting blocking device water outlet is located at current downstream direction, the moving direction of upper and lower cover plates is vertical with water (flow) direction, and when silting blocking device is by water impact, up and down cover plate can not be opened because of flow action, thus avoid silt particle to enter check valve inside from water outlet causing alluvial, anti-silting effective.
Reverse-stop type silting blocking device meets design requirement completely, avoids drainage system alluvial blocking, thus avoids underground water to damage channel, ensure that the safe operation of channel and the people of channel two sides and property safety.
