A kind of anti-silting type extra large cable anchors well
Technical field
The present invention relates to the device to extra large cable anchoring in submarine cable transmission line of electricity, especially a kind of anti-silting type extra large cable anchoring
Well.
Background technology
Submarine cable log in section due to the boundary positioned at flood and field, need extra large cable is anchored, prevent sea
Cable is subject to the impact of tide and wave to swing and lead to extra large cable impaired.For this reason, generally anchor is carried out to extra large cable using extra large cable anchoring well
Gu.
Cool in view of section is logged in extra large cable, when logging in section using extra large cable and laying cooling water pipe, cooling water
Pass through refrigerated sea water in pipe, while extra large cable anchoring well provides refrigerated sea water to give extra large cable cooling, take into account leading of refrigerated sea water
Into and out.Because cooling water pipe diameter is little(Generally between 0.4-0.8 rice), so having necessarily to the silt content of sea water
Requirement, containing the too many cooling water of the impurity such as silt particle, cooling water pipe can be resulted in blockage, impact extra large cable cool.
Content of the invention
The technical problem to be solved is the defect overcoming above-mentioned prior art to exist, and provides a kind of anti-silting type sea
Cable anchors well, and it can effectively fix extra large cable, and the refrigerated sea water being passed through is carried out precipitate silt particle and be automatically drained out silt particle, to prevent
Extra large cable anchors the cooling water pipe of well by silting.
For this reason, the present invention adopts the following technical scheme that:A kind of anti-silting type extra large cable anchors well, including well body with positioned at well body
The extra large cable anchorage clip of bottom it is characterised in that
The top of described well body is provided with a refrigerated sea water water inlet, forms a refrigerated sea water pond and and be located at cooling in well body
Sedimentation tank immediately below seawater inlet port, described sedimentation tank is communicated on the top of well body with refrigerated sea water pond, the bottom of sedimentation tank
Portion is provided with a sand removing hole communicating with the external world, and described extra large cable anchorage clip is located at the at the bottom of pond in refrigerated sea water pond;
It is provided with one positioned at the well body of extra large cable entrance side to communicate with the extraneous floating drum water inlet communicating with floating drum water inlet
Buoy lifting chamber, this buoy lifting intracavity puts a liftable floating drum;
The inner end axle of the sediment outflow baffle plate that can swing up and down is connected on the medial wall of sedimentation tank, the outer end of sediment outflow baffle plate
It is placed in outside well body by sand removing hole and uses cooperatively with floating drum, realize turning off or on of sand removing hole.
When the present invention uses, sea water promotes sediment outflow baffle plate to be rotated up the buoyancy of floating drum, until the middle part of sediment outflow baffle plate
Conflict on the roof of sand removing hole, now sand removing hole is in the state of being closed(I.e. at the incoming tide);When the sea water in sedimentation tank, silt particle
Gravity and sediment outflow baffle plate deadweight more than floating drum buoyancy when(I.e. at ebb tide, the now decline with sea water, the buoyancy of floating drum subtracts
Little), sediment outflow baffle plate rotates down, and the middle part of sediment outflow baffle plate is departed from the roof of sand removing hole, and sand removing hole is in open state, mud
Sand is discharged at sand removing hole.
The extra large cable anchoring well of the present invention is generally disposed at extra large cable and logs near section disengaging sea water section, protects in extreme low water
Card extra large cable entrance is located under tidal level;In minimum high tide level, the refrigerated sea water water inlet of anchoring well is located under tidal level.
Further, the top of described well body is provided with a backflow guide plate, and the bottom of this backflow guide plate is located in sedimentation tank, and returns
Form one between the top of the bottom of conductance plate and sedimentation tank medial wall to be used for entering the sea water after precipitation in refrigerated sea water pond
Inflow entrance.The refrigerated sea water being flowed into by water inlet is carried out water conservancy diversion by backflow guide plate, makes sea water form backflow, in the work of gravity
With under, the silt particle thing in sea water is deposited on sediment outflow baffle plate, the sea water after precipitation pass through flow back guide plate enter refrigerated sea water pond in.
Further, a drain pipe being communicated with refrigerated sea water pond, this drain pipe are connected on the well body of extra large cable entrance side
On be provided with an anti-silting cover plate equipped with a check valve, the mouth of pipe of drain pipe.Anti-silting cover plate covers drain pipe port at the incoming tide, prevents silt particle
Alluvial is in drain pipe port;Refrigerated sea water passes through the unidirectional outflow of check valve at ebb tide, and refrigerated sea water is gathered in pipe, reaches certain
During pressure, anti-silting cover plate is opened, and discharges refrigerated sea water.
Further, a cooling water pipe being communicated with refrigerated sea water pond is connected on the well body of extra large cable outlet side, described
Cooling water pipe is used for being enclosed within extra large cable and logs in section, logs in section cooling to extra large cable.
Further, equipped with filter screen on the inner face of described cooling water pipe.Sea water in refrigerated sea water pond is entered by filter screen again
Enter in cooling water pipe, prevent silt blocking cooling water pipe.
Further, described refrigerated sea water water inlet is 2-4 rice with the difference in height of floating drum water inlet, makes to exist up and down pressure
Difference, at the incoming tide float buoyancy can support the pressure that sea water pours in and silt particle gravity, sand removing hole is in the state of being closed.
Further, equipped with cat ladder on the medial wall in described refrigerated sea water pond, the well body top surface directly over cat ladder has
One manhole.Manhole is manhole, closes at ordinary times, needs to open during maintenance, maintainer can be entered by manhole, enters along cat ladder
In refrigerated sea water pond.
Further, the top of described well body is provided with an anti-collision warning device, and passing ships are reminded in warning, prevents from clashing into extra large cable
Anchoring well;Described anti-collision warning device includes ban board support and the LED ban board being arranged on ban board support and the sun
Energy charging panel, solar charging panel is powered to LED ban board, and warning red and white all brushed by ban board support and well body
Paint.The ship of warning paint warning process on daytime, LED ban board flashing reminds night ship to note anticollision.
Further, described refrigerated sea water water inlet is provided with metal grate, and metal grate is in order to slightly larger the moulding of blocking volume
The floating things such as strand foam, branch, water bottle enter in well body.
Further, extra large cable logs in section and accesses extra large cable anchoring well by extra large cable entrance, and is fixed in extra large cable anchorage clip, extra large cable anchor
Gu folder is arranged on anchor frame base.
The present invention anti-silting type extra large cable anchor Cementing application logs in section in submarine cable, solves this section of extra large cable anchoring fixation and asks
Topic, and refrigerated sea water is provided, and the refrigerated sea water being passed through is carried out precipitate silt particle and be automatically drained out silt particle it is therefore prevented that extra large cable anchor
The cooling water pipe of well cementation is by silting.
