Detailed Description
As shown in fig. 1 to 2, the outlet device of the vertical shaft at the underwater water outlet of the low-pressure water conveying pipeline comprises a vertical shaft 1 with a bottom plugged, and a mounting hole for accommodating the insertion of the water conveying pipeline 2 is formed in one side of the vertical shaft. And plugging the gap between the mounting hole and the water pipeline by using an anti-seepage material. The water conveying pipeline 2 can be an elbow pipeline 21 or a straight pipeline 22.
As shown in fig. 2, the end of the elbow pipe is provided with a blocking plate 23, and the blocking plate and the end of the elbow pipe are provided with a plurality of overflow holes 24. The overflow hole is designed to facilitate the water flow to enter the vertical shaft in a turbulent flow mode and then flow out of the vertical shaft, so that the phenomenon that a fountain is easily formed at the water outlet of the vertical shaft is avoided. FIG. 3 is a schematic diagram of a straight pipeline in use, and the principle is the same.
Fig. 4 is the utility model discloses add the structure schematic diagram when having out water grid 3, so add out water grid, reduce conduit rivers and arouse great undulant influence to the landscape surface of water, solve the shaft export simultaneously and block dirty poor problem of effect.
As shown in fig. 5 to 8, a plurality of sets of pressure spreading mechanisms are arranged in parallel on the water outlet grille 3, each pressure spreading mechanism includes a first shaft 31 and a second shaft 32, wherein a plurality of upper plates 33 are mounted on the first shaft, a plurality of lower plates are mounted on the second shaft, the upper plates and the lower plates are arranged at intervals, water discharging fluff is mounted in gaps between the adjacent upper plates or the adjacent lower plates, a middle pole 36 is mounted between the first shaft and the second shaft, and the upper plates and the lower plates are in contact with the middle pole and are placed on the upper side of the middle pole.
When water flow enters the vertical shaft from the water conveying pipeline, a large amount of turbulent water flows overflow from the overflow holes, the water outlet grille on the upper side of the vertical shaft is supported by the vertically upward water pressure, the upper plate and the lower plate rotate for a certain angle around the first shaft and the second shaft under the action of the water pressure, the direction of the water flow is changed while the pressure is reduced, and the fountain phenomenon caused by direct flushing of the water surface is avoided.
And the scheme is refined, and the density of the materials adopted by the upper plate and the lower plate is greater than that of water.
If the water pressure is small, a part of water flows out from the water discharging fluff, and at the moment, the upper plate and the lower plate are pressed on the middle pole to block the water flow from flowing out.
The scheme is further refined, as shown in fig. 7, two fixed disks 37 are respectively installed on two side walls of the shaft, a first shaft or a second shaft is respectively installed on the two fixed disks,
