Detailed description of the invention
Below the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
As shown in Figures 1 to 3, structure of fetching water comprises: water intaking box culvert 100 and channel of approach 200.
The vertical type box culvert that water intaking box culvert 100 is made for steel concrete.Water intaking box culvert 100 is that water intaking face 101 is (in the present embodiment towards the one side at the water sources such as rivers,lakes and seas, the water source of water intaking structure is seawater), surge chamber 110 is provided with in water intaking box culvert 100, surge chamber 110 is rectangular shape, the inwall of surge chamber 110 101 sides near water intaking face is front, the opening 111 of surge chamber 110 is being provided with vis-a-vis side, channel of approach 200 is provided with channel 210, the entrance width of channel 210 is greater than outlet 212 width, and the both sides inwall of channel 210 is from the import of channel 210 to outlet 212 rounding off.The import of channel 210 is docked with the opening 111 of surge chamber 110, and channel 210 is communicated with surge chamber 110.
Also be provided with at least two water intaking passages in water intaking box culvert 100, water intaking passage is provided with intake on water intaking face 101.Water intaking passage comprises officially enroll aquaporin 121 and side water intaking passage 122.Some (at least one) officially enroll aquaporin 121 be arranged near water intaking box culvert 100 in the middle part of position, aquaporin 121 of officiallying enroll is communicated with from the front of surge chamber 110 with surge chamber 110.Article four, water intaking passage 122 in side is divided into two groups, be located at the position of water intaking box culvert 100 near dual-side edge respectively, side water intaking passage 122 is communicated with from the side of surge chamber 110 with surge chamber 110, side water intaking passage 122 comprises the outer section, bending section, the inner segment that connect successively to surge chamber 110 direction from intake, outer section is arranged side by side with aquaporin 121 of officiallying enroll, inner segment by bending section towards the side to surge chamber 110.Side water intaking passage 122 is communicated with surge chamber 110 from the side, the inside making full use of water intaking box culvert 100 arranges water intaking passage, when the water intaking area of intake is identical, opening 111 width of surge chamber 110 is less than the overall width of water intaking box culvert 100, the import of channel 210 is directly docked with the opening 111 of surge chamber 110, the entrance width of channel 210 and opening 111 width of surge chamber 110 match, and channel 210 need not be made overall across water intaking box culvert 100, reduce the construction area of channel of approach 200, reduce costs, environment is more friendly.
When taking water, seawater enters surge chamber 110 from intake, then enters channel 210, and the condensing plant exporting 212 supply power plant via channel 210 uses, and the hot water of power plant's condensing plant discharge also can oppositely enter marine.Interchannel partition wall of fetching water doublely can do diversion pier, and flow rate of water flow is evenly distributed, and reduces water intaking structure to the disturbance of upper strata or low layer water body, and reduces entrainmenting fish.
The both sides Qu Bi of channel of approach 200 is generally and adopts the finely divided material of sandstone or stone to pile up to make, structure loosely, have by the risk of current scour loss, for this reason, for dodging the water impact flowed out from water intaking box culvert 100 in prior art, the width of channel 210 import of channel of approach 200 is greater than the width of water intaking box culvert 100, and the canal wall of channel of approach 200 and reinforcement walls 300 extend to face, place, water intaking face 101, take up an area huge, unfriendly to ecological environment, cost is high.In the present embodiment, water enters surge chamber 110 from intake by water intaking passage, then caused in power plant by channel of approach 200, by the buffering of surge chamber 110, the current introduced can not directly impact channel of approach 200, channel of approach 200 directly docks with the opening 111 of surge chamber 110, and need not extend to water source place, reduces the construction area of the length of channel of approach 200, reduces costs.
The inwall of channel is the round and smooth arc tangent with water intaking box culvert 100 back side (i.e. face, surge chamber 110 opening 111 place), is beneficial in the smooth and easy gently canalize 210 of water.Side water intaking passage 122 is provided with bending section, while reduction surge chamber 110 opening 111 width, the center flowing to surge chamber 110 of the current entering surge chamber 110 can be made, and just to the inwall of Ground shock waves channel 210, channel 210 inwall can not be reduced and be subject to washing away of current.Simultaneously, the cross section place of channel of approach 200 is provided with reinforcement walls 300, consolidation can be provided to support for piling up of building stones, channel 210 inwall of channel of approach 200 is tangent with water intaking box culvert 100 back side, the cross section of canal wall is positioned at the outside of the side of canal wall, at the joint of channel of approach 200 with water intaking box culvert 100, the width of channel of approach 200 is less than the width of water intaking box culvert 100, the outside of the canal wall of channel of approach 200 is inwardly made a concession formation relative to the outer wall of water intaking box culvert 100 and is made a concession recessed, reinforcement walls 300 be located at make a concession recessed in, channel of approach 200 and the total width of reinforcement walls 300 are not more than the width of water intaking box culvert 100 entirety, and, the maximum width of channel of approach 200 is less than or equal to the width in the front of water intaking box culvert 100, save building to take up an area, environmentally friendly, reduce costs.
As shown in 4,5 figure, water intaking box culvert 100 also includes load-carrying portion 130, and with the actual face of putting of box culvert 100 of fetching water for datum, load-carrying portion 130 is located at the top of water intaking box culvert 100, water intaking passage is located at the bottom of water intaking box culvert 100, and load-carrying portion 130 is positioned at the top of water intaking passage.Load-carrying portion 130 is provided with and takes up groove, takes up in groove to fill out to establish sandstone or other weights, plays the effect of suppression firm water intaking box culvert 100.The long-term high flow surface in top of water intaking box culvert 100, the upper limb absolute altitude of intake, less than or equal to 3m below the on-site mean low-water of water intaking structure, can be avoided the higher seawater of surface temperature, avoid sucking the floating foreign material of seawater surface.Further, intake lower edge absolute altitude greater than or equal to water intaking the on-site seabed of structure top 1m.Like this, the higher seawater of surface temperature and the more seawater of bottom silt can be avoided, get middle level low temperature seawater, can significantly reduce unit design back pressure, improve unit efficiency, alleviate the live load of filter plant.
Each technical characteristic of above embodiment can combine arbitrarily, for making description succinct, all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this manual is recorded.
Above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
