Description

Technical Field

[0001] The invention relates to a floating raft and an anchoring system thereof, belonging to the field of floating rafts. Background Art

[0002] my country's coastal nuclear power plants all use seawater as a cold source to provide cooling water for turbines and nuclear island equipment. In recent years, with the changes in the marine environment, nuclear power plant shutdowns caused by the invasion of marine organisms or marine garbage have occurred from time to time. In order to ensure the safety of the cold source system, each nuclear power plant has successively installed interception nets in the water intake open channel, relying on the larger flow area of ​​the net bag to achieve pre-filtration of circulating water. However, at present, all nuclear power plants use manual cleaning to clean up the garbage in the net bag, which is inefficient and cannot effectively deal with sudden outbreaks of marine organisms. The garbage cleaning operation in the net bag needs to be carried out by ships, and the safety risk of water operations is relatively high. When marine organisms suddenly break out, it is impossible to transport the cleaned marine organisms quickly, and it is impossible to use ships for continuous cleaning operations.

[0003] The invention patent with application number CN202011394633.7 discloses a retractable device for a nuclear power circulating water pre-filtration system, including a laying cable connected to a net bag, a net collecting cable connected to the net bag, a tensioning cable connected to the net bag, a retractable platform, a first retractable unit arranged on the retractable platform, a second retractable unit arranged on the retractable platform, and a third retractable unit arranged on the retractable platform; the first retractable unit is connected to the net collecting cable to drive the net collecting cable to telescopically move to achieve net laying or net collecting; the second retractable unit is connected to the laying cable to drive the laying cable to telescopically move to achieve net collecting or net laying; the third retractable unit is connected to the tensioning cable to drive the tensioning cable to telescopically move to assist the laying cable to lay the net. The retractable device for a nuclear power circulating water pre-filtration system realizes the full-section interception of the filtration system, so that the filtration system is effectively protected and the replacement efficiency of the filtration system can be improved. However, when the net is full of garbage, manual cleaning is usually used to clean the garbage in the net, which is inefficient and cannot effectively deal with sudden outbreaks of marine organisms. The cleaning operation of the garbage in the net needs to be carried out by ships, and the safety risk of water operations is relatively high. When marine organisms suddenly break out, it is impossible to transport the cleaned marine organisms quickly, resulting in the inability to use ships for continuous cleaning operations.

DETAILED DESCRIPTION

[0025] like Figure 1-4As shown, a floating row and its anchoring system in this embodiment include a floating row body 12 formed by sequentially splicing a plurality of floating row modules 11. Garbage at the tail of the net bag 5 can be cleaned on the floating row body 12 without the need for cooperation from a surface vessel. The sustainability of the interception function of the interception net can be ensured when marine organisms suddenly break out, and the rapid transportation of garbage is achieved with high cleaning efficiency. When a single floating row module 11 is damaged, it can be quickly replaced. Anchor chains 13 are provided on the upstream and downstream sides of each floating row module 11. One end of the anchor chain 13 is fixedly arranged on the floating row body 12. The other end of 13 is provided with an anchor 14, which is a delta anchor. The delta anchor is connected to the anchor chain 13 through a shackle. The weight of the delta anchor is 1 ton. The use of the delta anchor for anchoring can provide a large anchoring force. Anchor chains 13 and anchors 14 are provided in the upstream and downstream directions of the floating row body 12 to improve the stability of the floating row body 12. An adjusting mechanism 15 is provided at the bottom of each floating row module 11. The level of the floating row body 12 is adjusted by the adjusting mechanism 15 to reduce the inclination of the pedal 11.1 caused by waves, and further improve the stability of the floating row body 12.

[0027] The regulating mechanism 15 comprises a regulating tube 15.1 fixedly arranged horizontally at the bottom of the bracket 11.2, the regulating tube is arranged opposite to the bracket 11.2, the two ends of the regulating tube 15.1 are arranged in the upstream and downstream directions respectively, and the two ends of the regulating tube 15.1 are provided with air bags 15.2, two regulating plates 15.3 are arranged in the regulating tube 15.1 at intervals, the regulating plates 15.3 are slidably and sealedly connected with the regulating tube 15.1, and a moving component 15.4 is arranged between the two adjusting plates 15.3, and the moving component 15.4 drives the two adjusting plates 15.3 to move synchronously in the regulating tube 15.1 along the length direction of the regulating tube 15.1. When waves appear, the waves move from the upstream of the bracket 11.2 to the downstream of the bracket 11.2, and cause the bracket 11.2 to tilt, that is, the floating row module 11 is tilted, and when the tilt amplitude reaches a certain degree, the adjusting plate 15.3 is moved inward in the adjusting tube 15.1 by the moving assembly 15.4, and the air in the airbag 15.2 at the tilted high position is transported to the adjusting tube 15.1 to shrink the airbag 15.2, and the air in the adjusting tube 15.1 is transported to another airbag 15.2 to expand the airbag 15.2, and the buoyancy generated by the expanded airbag 15.2 is greater than that of the reduced airbag 15.2, that is, the buoyancy of the bracket 11.2 at the expanded position of the airbag 15.2 is greater than that of the bracket 11.2 at the reduced position of the airbag 15.2, and the buoyancy generated by the buoyancy difference is used to lift the height difference of the bracket 11.2, and offset the tilt caused by the waves pushing up the bracket 11.2, that is, the floating row module 11 is always within a certain tilt angle, avoiding the tilt angle being too large to affect the stability.

[0028] The moving assembly 15.4 includes a lead screw 15.41, one end of which is driven by an adjusting motor 15.42, a slider 15.43 is threadedly connected to the lead screw 15.41, a transmission rod 15.44 is fixedly arranged on the top and bottom of the slider 15.43, the transmission rod 15.44 and the lead screw 15.41 are parallel to the adjusting tube 15.1, and the two ends of the lead screw 15.41 are respectively fixedly arranged on two adjusting plates 15.3, and the adjusting motor 15.42 drives the lead screw 15.41 to rotate, so that the slider 15.43 moves axially on the lead screw 15.41 along the adjusting tube 15.1, and the movement of the slider 15.43 drives the two adjusting plates 15.3 to move synchronously through the transmission rod 15.44.

[0029] The bracket 11.2 is provided with a level sensor 15.45 and a PLC 15.46, and the level sensor 15.45 and the adjustment motor 15.42 are both connected to the PLC 15.46. The level sensor 15.45 detects the levelness and then transmits the data to the PLC 15.46. After calculation, the PLC 15.46 enables the adjustment motor 15.42 to drive the lead screw 15.41 to start, so that the adjustment plate 15.3 moves a corresponding distance according to the levelness, thereby realizing intelligence.
