Description

Technical Field

[0001] The invention belongs to the technical field of emergency transfer systems, and in particular relates to a reinforced steel cable type shipborne hazardous chemicals accident emergency transfer system and a laying method thereof. Background Art

[0002] my country's conventional emergency transfer technology for shipborne hazardous chemicals adopts a floating pipeline, that is, a transfer hose is used to connect the shore and the accident ship, and then the liquid hazardous chemicals in the accident ship are transferred to the shore through the shore pumping system. However, this technical solution has poor environmental adaptability. In inland areas with high water flow rates, the transfer hose may be broken, resulting in leakage of liquid hazardous chemicals during emergency transportation, seriously polluting the waters and damaging the ecological environment. Summary of the invention

[0003] In view of this, the present invention provides a reinforced steel cable type shipborne hazardous chemicals accident emergency transfer system and its laying method, which can perform long-distance emergency transfer of shipborne hazardous chemicals under high flow conditions in inland rivers, and improve the emergency handling capability of shipborne hazardous chemicals accidents under extreme conditions.

[0004] The present invention is achieved through the following technical solutions:

[0005] A reinforced steel cable type shipborne hazardous chemicals accident emergency transfer system, comprising: an operating boat, an on-water pumping platform, a shore hazardous chemicals storage platform, a suction hose, a delivery hose, a fixed steel cable, a hydraulic winch and a pipe clamp;

[0006] The working boat is used to tow the fixed steel cable and the conveying hose, and to move the water pumping platform to a set position;

[0007] The fixed steel cable is wound around a hydraulic winch; the hydraulic winch is installed on the beach, and the end of the fixed steel cable on the hydraulic winch is connected to the accident ship carrying liquid hazardous chemicals under the action of the working boat;

[0008] The above-water pumping platform is composed of two or more pontoon modules, and a generator set and a suction pump are installed on the platform. The generator set is used to provide power to the suction pump, and the suction pump is used to suck and pump the liquid hazardous chemicals on the accident ship; under the action of the workboat, the above-water pumping platform moves to a position set at a distance from the accident ship, and the input end of the suction pump extends into the storage tank containing liquid hazardous chemicals in the accident ship through a suction hose;

[0009] The beach hazardous chemicals storage platform is used for storing liquid hazardous chemicals, and the beach hazardous chemicals storage platform is installed on the beach;

[0010] The delivery hose is a transfer channel for liquid hazardous chemicals, one end of which is connected to a storage container in the shore hazardous chemicals storage platform, and the other end is connected to the output end of the suction pump of the water pumping platform under the action of the working boat;

[0011] The pipe clamp is used to connect the fixing steel cable and the conveying hose together, and two or more pipe clamps are arranged at intervals.

[0012] Furthermore, it also includes a buoyancy component; two or more of the buoyancy components are installed at intervals on the fixed steel cable to bear the weight of the liquid hazardous chemicals, the conveying hose and the fixed steel cable, so that the conveying hose can float on the water surface.

[0013] Furthermore, the buoyancy component is a floating ball or a buoy.

[0014] Furthermore, the hydraulic winch has a mechanical braking function for keeping the fixed steel cable in a taut state.

[0015] Furthermore, the delivery hose is located on the side of the flow-facing surface of the fixed steel cable.

[0016] Based on the above-mentioned method for laying a reinforced steel cable type shipborne hazardous chemicals accident emergency transfer system, the specific steps are as follows:

[0017] Step 1: Fix the hydraulic winch on the beach, and wind one end of the fixed steel cable around the hydraulic winch, connect the other end to the working boat, and use the working boat to pull the fixed steel cable and sail towards the accident ship;

[0018] Step 2: The working boat sets buoyancy components at set intervals while pulling the fixed steel cable toward the accident ship;

[0019] Step 3: After the working boat reaches the set distance from the accident ship, connect the other end of the fixed steel cable to the accident ship, and then use the hydraulic winch to pull the fixed steel cable in the opposite direction to keep the fixed steel cable in a taut state;

[0020] Step 4: Use the workboat to move the water pumping platform to a set distance from the accident ship and anchor it;

[0021] Step 5: Connect one end of the delivery hose to the hazardous chemicals storage platform on the shore, and the other end to the work boat, and drive the work boat to the water pumping platform. While the work boat pulls the delivery hose, use a pipe clamp to connect the oil delivery hose to the fixed steel cable at set intervals;

[0022] Step 6: After the working boat travels to the set distance from the water pumping platform, connect the other end of the delivery hose to the output end of the suction pump of the water pumping platform;

[0023] Step 7: Extend one end of the suction hose into the set position of the storage tank for liquid hazardous chemicals of the accident ship, and connect the other end of the suction hose to the input end of the suction pump.

[0024] Furthermore, in step seven, one end of the suction hose is extended into the storage tank of the liquid hazardous chemicals of the accident ship in the following manner:

[0025] A hole is drilled at the set position of the storage tank for liquid hazardous chemicals on the accident ship, and then a flange made of sealing material is installed at the opening position and fixed. The flange is then connected to one end of the ball valve, and the other end of the ball valve is connected to one end of the suction hose.

[0026] Furthermore, in step seven, during the process of pumping liquid hazardous chemicals, the operating boat reciprocates along the length direction of the delivery hose to perform regular inspections of the transfer system.

[0027] Beneficial effects: The present invention improves the environmental adaptability of the accident emergency transfer system by adding a fixed steel cable, can adapt to operations under high flow rates, has a fast installation speed, and can avoid leakage accidents of liquid hazardous chemicals when the conveying hose is broken.
