On, the top of protective casing 5 is fixedly linked by fixed mount with the pre-buried anchor on the borehole wall 13.Circulating pump in the present embodiment can be
Immersible pump, is preferably to protect circulating pump, and its height of the protective casing in the present embodiment is more than the height of immersible pump, at least dives
More than 3 times of water pump height.
To ensure that the seawater in seawater siphon recovery well can use in real time, the present embodiment is provided with two in seawater siphon recovery well
The individual circulating pump 3 and two seawater pipelines 4, one of circulating pump 3 are used as stand-by pump, another circulating pump
3 be working barrel.When working barrel needs to overhaul or broken down, stand-by pump can be opened.Preferably to meet installing space
It is required that, the outlet of two circulating pumps 3 is oppositely arranged in the present embodiment.
For ease of construction, above-mentioned circulating pump 3 along guide rail 6 by directly gliding come Fast Installation, and above-mentioned guide rail 6 passes through connection
Part 7 is connected with above-mentioned seawater pipeline 4.And seawater pipeline 4 is fixed on the borehole wall by fastener 2, such as by anchor ear by seawater pipe
Road is confined, and then anchor ear is fixedly linked with the borehole wall by bolt etc..In the present embodiment seawater pipeline 4 along the borehole wall 13 it is vertical to
On, the fastener 2 is the anchoring piece being fixed on the borehole wall 13, and segmentation fixation is carried out to seawater pipeline 4 by anchoring piece.For just
In construction and maintenance, the power cable and control cable of above-mentioned circulating pump 3 are arranged in a row composition cable row, and cable, which is arranged, to be passed through
Auxiliary fixing member segmentation is fixed.
To save energy consumption, and it is easy to the circulating pump in regulation, the present embodiment to be variable frequency pump.
The seawater pipeline 4 in embodiment, the present embodiment is used as the one of the seawater taking device extracting seawater of the present invention
Outlet be connected with the heat-exchanger rig being placed in Natural gas pipeline system, be such as connected with the import of seawater heat exchanger, seawater to make heat exchange
Device can be made full use of the seawater preheating of extracting seawater, realize the use of seawater preheating.Such as by seawater heat exchanger be placed in
In the connected natural gas line of expander outlet, for heating the cryogenic natural gas after acting.
As another use embodiment of the seawater taking device extracting seawater of the present invention, the outlet of seawater pipeline 4 passes through
Condenser is connected with the water inlet pipe of closed cold device in one branch pipe unit circulation, when may be implemented in compressor emergency shutdown with this, passes through
Circulating pump 3 cools down the standby water of circulation to provide unit, and thoroughly closes non-the big of condenser offer cooling water and follow pump, saves
The energy consumption of overall unit.
Based on existing power plant, how above-mentioned seawater taking device is set, the present invention also provides a kind of seawater of power plant
The seawater taking device of power plant in the construction method of taking device, the present embodiment takes for the seawater of power plant as described above
With device, concrete construction method is：First, by the seawater emptying in the seawater siphon recovery well of power plant, as shown in Fig. 1 and Fig. 2,
Fixed again in shaft bottom it is described connect termination 9 soon, gradually lay seawater pipeline 4 upwards from shaft bottom, and make seawater pipeline 4 and the phase of the borehole wall 13
Fixed, the bottom of seawater pipeline 4 is connected and communicated with connecing termination 9 soon, and guide rail 6 is laid along seawater pipeline 4, and circulating pump 3 is along leading
Rail 6 glides and is connected and interfixes with connecing termination 9 soon.The construction method of the present embodiment its need by the seawater siphon of power plant return
The seawater emptying in well is received, is then set according to present situation in well and connects termination 9 and seawater pipeline 4 soon, most the edge of circulating pump 3 at last
Guide rail 6 glides and fixed, and whole work progress short time consumption is short, and makes power plant's downtime short, the installation of circulating pump 3 side of connecing soon
Just.
To stablize above-mentioned whole seawater taking device, sea of the present embodiment in the seawater siphon recovery well by the power plant
After water emptying, first constructed in the shaft bottom mounting seat 8 being made up of armored concrete and support base as shown in Figure 2, then will be described
Connect termination 9 soon to be fixed in mounting seat 8, guide rail bottom is fixed on support base.The present embodiment is in shaft bottom construction generation reinforcing bar
Concrete pad, i.e. mounting seat 8 and support base, termination and guide rail are connect with this soon to consolidate, and it can also be by setting in shaft bottom
The firm seat of other forms connects termination and guide rail soon to consolidate, and only needs shock resistance and corrosion-resistant, is not described in detail here.
For ease of the firm laying of seawater pipeline and guide rail, the present embodiment lays fixed seawater pipe also on the above-mentioned borehole wall 13
The anchoring piece in road 4 and guide rail 6.
Further to avoid the circulating pump 3 in impact of the well maritime interior waters to seawater pipeline and circulating pump, the present embodiment and institute
State connect soon termination 9 arrangement need meet：The circulating pump 3 and the line of centres for connecing termination 9 soon, with connecing from circulating pump 3 and soon end
The first 9 nearest boreholes wall are parallel.Seawater pipeline and circulating pump i.e. in the present embodiment press close to same borehole wall arrangement.
