Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail, but this embodiment should not be construed limitation of the present invention, only for example, simultaneously by illustrating that advantage of the present invention will become clearly and easy understand.
Before powerplant intakes trashrack, floating thing induction system is the floating thing treatment system be arranged on hydroelectric station dam, comprises interception gripping portion and transport portion;
Interception gripping portion comprises: some gate piers 11 of hydroelectric station dam upstream side; Gate slot group 13 is provided with between some gate piers 11; Gate slot group 13 updrift side is provided with inlet opening 10; Gate slot group 13 is generally trash rake gate slot, trashrack gate slot and draining bottom outlet maintenance gate slot from upstream to downstream direction.Multiple gate slot can control to open by functional requirement, and interception may enter the floating thing 14. of water wheels impact generating
Gate pier 11 is also provided with the wharf portal crane track 12 of double rail type; Wharf portal crane track 12 is provided with gate-type trash rake 9; Gate-type trash rake 9 is connected with gate-type trash rake grab bucket 92 by gate-type trash rake mechanical arm 91;
Transport portion comprises: the main sealing-tape machine 4 of hydroelectric station dam upstream side plank road formula; Main sealing-tape machine 4 is supported by the section steel beam 3 of lower end, both sides; Section steel beam 3 is arranged on the cantilever bracket 2 of below; Main sealing-tape machine 4 downstream is also provided with wave wall 7.The plank road formula design of main sealing-tape machine 4, does not go the confined space taking original dam body, is especially applicable to built power station and builds.
Conventional sealing-tape machine induction system is all arrange on the ground, relies on bottom bracing structure to build operation platform, and therefore it is built, runs the enough places of needs and space.The present invention is upstream face design arrangement floating thing sealing-tape machine induction system near water outside the dam body of power station, does not take any space of dam end face, avoids and causes interference to the normal operation of dam existing equipment (such as door machine, trashrack etc.).
Conventional sealing-tape machine delivery system device is made up of belt of adhesive tape machine, cylinder and motor, carrying roller, middle frame, supporting leg, and elevation is generally at more than 1m, and height space requires higher.Present invention eliminates middle frame and the supporting leg of sealing-tape machine delivery system device, adopt section steel beam 3 and cantilever bracket 2 to support, effectively reduce structure height.
Preferably, major bearing structures cantilever bracket 2 of the present invention is connected with adopting rear anchoring chemical anchor bolts 1 between dam concrete, carries out anchoring by Chemical Felter and concrete adhesion stress.Its anchorage length can be deep into steel concrete internal core district, and anchoring is firm, all applicable on newly-built or built dam.Can promote the use of the equal tool of key water control project that there is floating thing blocking water inlet problem.
Preferably, main sealing-tape machine 4 upstream side is also provided with access path 8.
Preferably, main sealing-tape machine 4 and access path 8 periphery are provided with and totally-enclosedly go along with sb. to guard him 6; Wherein totally-enclosed upper surface of going along with sb. to guard him 6 goes along with sb. to guard him part for profiled sheet cover 61; Profiled sheet cover 61 is provided with some floating thing receiving openings 62.Such design, to the protection be provided in main sealing-tape machine 4 under various meteorological condition, makes the rubbish in floating thing 14 can not pollute the environment of dam body.
Preferably, floating thing receiving opening 62 lower end is provided with hopper 5, makes floating thing 14 enter main sealing-tape machine 4 system more smooth-going.
Preferably, main sealing-tape machine 4 is three-roller type sealing-tape machine, and form haul concave surface, the sealing-tape machine of comparing plane structure improves carrying capacity.
Preferably, main sealing-tape machine 4 end arranged beneath has longitudinally secondary sealing-tape machine 41; Longitudinally also be furnished with laterally secondary sealing-tape machine 42 below secondary sealing-tape machine 41 end.Floating thing 14 smoothly can fall into the sealing-tape machine of lower end from the sealing-tape machine of upper end, and many sealing-tape machines cooperatively interact like this, wriggles and connects, and to adjust the building structure of the complexity adapted on dam structure, floating thing is transported to two sides to be further processed.
For Ge Zhou Ba: Gezhouba second Channel powerplant installs 7 generating sets altogether, before dam, face length degree is about 320m near water, and a unit has 3 water inlets, 7 generating set totally 21 inlet openings, crest access is wide about 6.5 meters, when clearing up 21 hole floating thing of water inlet, a large amount of automobile stop, at crest access, causes traffic congestion, add the discontinuity of Automobile Transportation, transport capacity is reduced greatly, and the floating thing sewage crossing current salvaged, causes dam crest environment pollution.Floating thing quantity of slag when flood season is large, and the non-flood period quantity of slag is little, and the haulage devices such as automobile are by requirement configuration in flood season, and the utilization rate therefore in 1 year is relatively low, and maintenance costs is large, causes waste.Use sealing-tape machine supply line transport floating thing, equipment investment is little, late maintaining expense is low, there is continuative transport ability, advantage that freight volume is large, simultaneously, sealing-tape machine supply line, according to dam crest existence conditions, is arranged in face near a river, dam crest upstream, does not disturb Transformation Plan of Gantry Crane operation, mechanical transport, affects, the floating thing sewage salvaged flows into the Changjiang river, does not affect dam crest environment.
Sealing-tape machine supply line overall length 300 meters, transport capacity is 150 ~ 300t/h, and it is 10000 yuan that supply line builds peace engineering (containing equipment) every meter of cost, production shift: 20 hours/day; 25 days/month.
Automobile Transportation scheme, according to dam crest road and facility condition, can select the Automobile Transportation floating thing of 10 ~ 15t.By annual cleaning 150,000 m
3floating thing is considered, sees the following form 1 by price level sealing-tape machine supply line annual operating and maintenance cost in 2009.
Table 1 sealing-tape machine, Automobile Transportation annual operating and maintenance cost summary sheet
It should be noted that: to those of ordinary skill in the art, can also make some changes or distortion to the present invention under the prerequisite not changing the principle of the invention, this belongs to protection scope of the present invention equally.
