Pin-connected panel intake under a kind of ocean water that the utility model provides, it comprises the foundation trench of being located at sea bottom surface and is fixed at least two interior box culverts of this foundation trench abreast, on the side plate of each box culvert, be equipped with water inlet and through hole, and the side plate of a box culvert is provided with delivery port therein, the through hole of adjacent two box culverts connects, on the upper surface of the top board of each described box culvert, be provided with upwardly extending watertight shutter, surround a chamber after the watertight shutter butt joint of adjacent two box culverts, in this chamber, be provided with the steel concrete junction plate, and pre-buried connecting reinforcement stretches in this junction plate in the box culvert top board.
Preferably, be provided with at the joint of the joint of adjacent two described watertight shutters and adjacent two described box culvert top boards and be used for the rubber seal that anti-sealing enters described chamber.
Preferably, described connecting reinforcement is " X " shape, plays the effect of two-way shearing resistance, and is consistent with the action characteristic of wave.
Preferably, described watertight shutter and described box culvert are formed by formed by integrally casting reinforced concrete.
Preferably, described watertight shutter is a thin wall construction, and its thickness is 150～200mm, removes unnecessary watertight shutter to make things convenient for the junction plate construction to solidify the back.
Preferably, all described box culverts are along arranged in a straight line, and the flat shape after all described box culvert assembly units is rectangle or rhombus.
Preferably, be provided with trashrack in described water inlet.
Preferably, the weight of each described box culvert is all less than 500 tons.
Compared with prior art, the utlity model has following advantage.
(1) pin-connected panel intake under the ocean water of the present utility model, the bottom of each box culvert is fixed in the foundation trench, and top connects into integral body by connecting reinforcement and junction plate, and good stability has improved capacity of anti-storm.
(2) pin-connected panel intake under the ocean water of the present utility model, easy construction, the reliability height, cost of investment is low.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
One of them embodiment of the present utility model is shown in Fig. 3 to 6, the pin-connected panel intake comprises the foundation trench 6 of being located at sea bottom surface and is fixed on this foundation trench 6 interior three box culverts 1,2,3(also can be two or more under the ocean water, intake is a plurality of when big, every box culvert Weight control is below 500t, to make things convenient for the transportation by driving lifting), box culvert adopts steel concrete to make, and is prefabricated on land or the half latent barge on the coast.Three box culverts 1,2,3 are along arranged in a straight line, and the flat shape after the assembly unit is rectangle (also can be rhombus).The through hole 12,23,24,32 of the inner chamber of three box culverts through being located on its side plate is communicated with.On the side plate of the same sides of three box culverts 1,2,3, offer water inlet 13,25,33, and be provided with trashrack 9, be used for tackling the floating thing of water, avoid the floating thing in the water to enter intake at water inlet 13,25,33 places.Offer two delivery ports 26 on the box culvert 2 of centre and its water inlet 25 opposing sideplates, this delivery port 26 is communicated with diversion box culvert 7, and all is embedded with rubber fastening band 83 sealings at box culvert 2 and diversion box culvert 7 joints.
On the upper surface of the top board of box culvert 1,2,3, be provided with upwardly extending watertight shutter 11,21,22,31, watertight shutter 11,21,22,31 end faces exceed construction period seawater position 500mm(as shown in Figure 6) more than, remove for convenience and anti-seawater corrosion, watertight shutter adopts thin wall concrete structure, about 180 mm of thickness of slab.After box culvert is installed splicing, two watertight shutters of adjacent two box culverts surround a chamber, top board joint at two watertight shutters and box culvert all is embedded with rubber fastening band 81,82 sealings, the condition that provides junction plate 4 concrete that can drain water or avoid building to be washed away by current for construction junction plate 4.
In the chamber that watertight shutter surrounds, be provided with the steel concrete junction plate, and pre-buried " X " shape connecting reinforcement 5 stretches in this junction plate in the box culvert top board.Connecting reinforcement 5 is used to strengthen the top board of box culvert and being connected of junction plate 4, plays the effect of two-way shearing resistance, and is consistent with the action characteristic of wave.
Bring into play effect of contraction jointly by the underwater concrete of box culvert bottom, junction plate 4 and " X " shape connecting reinforcement at box culvert top, the intake box culvert of piecemeal is connected into overall structure, thereby reach the stability requirement of satisfying the intake box culvert.
The job practices of intake of the present utility model is as follows.
(1) on the coast or half dive prefabricated box culvert and watertight shutter on the barge.
(2) earlier about the about 2.0m of the seabed excavation foundation trench 6(degree of depth), the fill block stone throwing bedding 61 again, leveling.；
