Description
Technical field
The utility model relates to Hydraulic Engineering Design field, is specifically related to the siphon discharging device in power station.
Background technology
As everyone knows, downstream, power station is generally open channel, in particular cases, there is certain between power station and downstream river course to intercept, such as earth clearance is particularly thorny or be subject to the restriction of terrain and its features, cannot excavate open channel and be communicated with between power station with downstream river course, also cannot Pipes Buried Deep Underground or adopt push pipe to be communicated with.
Summary of the invention
The purpose of this utility model is: the siphon discharging device providing a kind of power station, when power station delivery port with exist between downstream river course certain obstruct the schemes such as open channel, Pipes Buried Deep Underground or push pipe can not be selected to be communicated with downstream river course in power station time, adopt syphon to realize being communicated with of power station and downstream river course.
Technical solution of the present utility model is: connect siphon discharging device at draft tube of hydropower station end, this siphon discharging device comprises syphon and pumped vacuum systems, syphon is totally-enclosed antiseep concrete reinforced pipe, its one end is connected with draft tube of hydropower station, its other end is submerged in downstream river course and designs the following certain depth of minimum generating water level, and pumped vacuum systems is arranged on syphon.
Wherein, syphon comprises ascent stage, hump section, descending branch, and every 20m establishes seam along its length, (contains and the parting between draft tube of hydropower station) and is connected with U-shaped metallic water stop sheet, U-shaped metallic water stop sheet outward opening, filled bitumen flax silk in seam between seam.
Wherein, the design pressure of siphonal hump section is greater than the pressure for vaporization of water, and it is high that vacuum is not more than 7.5m water column.
Wherein, install pumped vacuum systems in siphonal hump section, pumped vacuum systems is made up of vacuum pump, vacuum tank, pipeline, air admission valve, vacuum meter, and pipeline one end connects syphon, the pipeline other end connects vacuum pump and vacuum tank, pipeline connects air admission valve and vacuum meter.
The beneficial effects of the utility model are: when 1, cannot be communicated with by measures such as excavation open channel, Pipes Buried Deep Underground or push pipes when between power station with downstream river course, adopt siphon water-out manners can realize being communicated with of power station and downstream river course, solve similar water power station water outlet difficult problem; 2, adopt after siphon discharging device without the need to arranging downstream access door.
Accompanying drawing explanation
Fig. 1 is power station siphon discharging device elevational schematic view.
Fig. 2 is syphon parting sealing piece scheme of installation.
In figure: 1 draft tube of hydropower station, 2 syphons, 3 pumped vacuum systems, 4 U-shaped metallic water stop sheets, 5 Bituminous hemp fibers.
Detailed description of the invention
As shown in Figure 1, 2, siphon discharging device is connected at draft tube of hydropower station 1 end, this siphon discharging device comprises syphon 2 and pumped vacuum systems 3, syphon 2 is totally-enclosed antiseep concrete reinforced pipe, its one end is connected with draft tube of hydropower station 1, its other end is submerged in downstream river course and designs the following certain depth of minimum generating water level, and pumped vacuum systems 3 is arranged on syphon 2.
Wherein, syphon 2 comprises ascent stage, hump section, descending branch, and every 20m establishes seam along its length, (contains and the parting between draft tube of hydropower station) and is connected with U-shaped metallic water stop sheet 4, U-shaped metallic water stop sheet outward opening, filled bitumen flax silk 5 in seam between seam.
Wherein, the design pressure of the hump section of syphon 2 is greater than the pressure for vaporization of water, and it is high that vacuum is not more than 7.5m water column.
Wherein, install pumped vacuum systems 3 in the hump section of syphon 2, pumped vacuum systems 3 is made up of vacuum pump, vacuum tank, pipeline, air admission valve, vacuum meter, and pipeline one end connects syphon, the pipeline other end connects vacuum pump and vacuum tank, pipeline connects air admission valve and vacuum meter.
During start generating, first start pumped vacuum systems, make syphon 2 fill water body, then open stator, gate makes turbine-generator units put into operation; When satisfying the requirements, also first can open stator, gate and air admission valve to the exhaust of syphon 2 water-filling, close air admission valve startup pumped vacuum systems 3 after acquiring a certain degree again and be vented, can capacity be reduced like this, shorten the pumpdown time; Regularly should start vacuum pump in running and get rid of infiltration gas in syphon 2, maintain vacuum tank vacuum and be not less than design of siphon pipes vacuum; General not emptying syphon when turbine-generator units short-term is stopped transport, is not vented when being conducive to putting into operation next time or few exhaust; Open air admission valve during maintenance to tonifying Qi in syphon 2, get rid of water body in syphon, do not need to arrange downstream, power station access door.
