Abstract
The present invention discloses a silt-preventing type submarine cable anchoring shaft. Current submarine cable anchoring shafts have certain requirements for the silt content of sea water, cooling water containing too many impurities such as mud and sand may block cooling water pipes, thereby influencing cooling and temperature reduction of submarine cables. The silt-preventing type submarine cable anchoring shaft is characterized in that a cooling sea water inlet is disposed in the top part of a shaft body, a cooling sea water tank and a sedimentation tank disposed right below the cooling sea water inlet are formed inside the shaft body, the sedimentation tank is communicated with the upper part of the cooling sea water tank on the shaft body, a sand draining port communicating with the outside is disposed in the bottom part of the sedimentation tank, a submarine cable anchoring clamp is disposed at the tank bottom of the cooling sea water tank, a float bowl water inlet communicating with the outside and a float bowl lifting cavity communicating with the float bowl water inlet are disposed on the shaft body at a submarine cable inlet side, and a liftable float bowl is disposed inside the float bowl lifting cavity. Mud and sand of the inlet sea water can be precipitated and automatically drained, thereby preventing the cooling water pipes of the submarine cable anchoring shaft from being blocked.
Description
Technical field
The present invention relates to the device to extra large cable anchoring in submarine cable transmission line, especially a kind of anti-silting type sea cable anchoring well.
Background technology
The section of logging in of submarine cable, owing to being positioned at the boundary of flood and field, needs to carry out anchoring to extra large cable, prevents extra large cable be subject to the impact of tide and wave and swing and cause extra large cable impaired.For this reason, extra large cable anchoring well is usually adopted to carry out anchoring to extra large cable.
Consider and cool to the extra large cable section of logging in, when utilizing the extra large cable section of logging in lay cooling water pipe, by refrigerated sea water in cooling water pipe, extra large cable anchoring well takes into account importing and the outflow of refrigerated sea water while providing refrigerated sea water to give the cooling of extra large cable.Due to cooling water pipe diameter little (usually between 0.4-0.8 rice), so have certain requirement to the silt content of seawater, containing the cooling water that the impurity such as silt particle are too many, can result in blockage to cooling water pipe, affect extra large cable and cool.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming the existence of above-mentioned prior art, a kind of anti-silting type sea cable anchoring well is provided, it can effectively fix extra large cable, and carries out precipitation silt particle to the refrigerated sea water passed into and automatically discharge silt particle, to prevent the cooling water pipe of extra large cable anchoring well by silting.
