Abstract
The invention relates to an overhead dragging and energy dissipating type ship arresting system supported by a floating foundation. The ship arresting system comprises the floating foundation, support frames, arresting cables (or nets), an anchor system and the like, wherein the support frames are arranged on the floating foundation, and are used for supporting the arresting cables (or nets) to the design heights. The height of each arresting cable (or the uppermost arresting cable on the arresting net) is higher than the maximum height of the ship head or the ship tail. When a ship hits the arresting cables (or nets), the arresting cables (or nets) and gravity anchors connected with the arresting cables (or nets) are driven to move to a bridge, the kinetic energy of the ship can be consumed in the dragging process of the gravity anchors, and finally the ship is prevented from moving close to the bridge. During dragging, the drag of each gravity anchor is approximately in direct proportional to the gravity, so the dragging distance after the ship hits the arresting cables (or nets) is controlled by designing the weight of each gravity anchor. A fixing foundation is not adopted for the arresting facility, and the arresting facility easily restores after being hit.

Another kind of being arranged on outside the certain distance that non-navigable comes shipboard.Block the compositions such as chain (rope or net) as patent of invention ZL200510095592.0 and utility model patent ZL200620025697.9, ZL201020138761.0, the disclosed fender system of ZL201020697102.0 by the gravity block (anchor) that is arranged at the end, sea (water) and the water surface.This type of fender system, if adopt steel material to make, its surface floating body that is arranged at (floating drum) and the anchor chain fixed etc. are subject to seawater corrosion; If the employing composite material, because exposing in the sun, its be arranged at the water surface to block parts easily aging.Therefore, the useful life of this type of fender system is relatively short, and maintenance cost is higher.
Due to when blocking boats and ships, if boats and ships are horizontal turn after its horizontal water resistance much larger than vertical water resistance, the mooring floating is blocked facility and need be put anchoring force and satisfy and to block the anchorage facility of requirement, otherwise can't finally block boats and ships.ZL201120293789.6 utilizes the check cable (or net) higher than the stem height, can block driftage and drift boats and ships, but that its bracing frame is is fixed, and is higher at the expenditure of construction of profundal zone.
Summary of the invention
In order further to reduce the expenditure of construction that blocks ship's repairs ﹠ maintenance facilities, adapt to better SEA LEVEL VARIATION and profundal zone application requirements, the invention provides a kind of elevated dragging energy eliminating type ship blocking system that is supported by floating foundation.
The technical solution adopted for the present invention to solve the technical problems is: utilize floating foundation to support check cable (or net), the height of check cable (or going up a check cable in arresting net most), higher than the height of bow and stern, lower than the height of works on ship; There is gravity anchor in the two ends system of check cable (or net), can be also gravity anchor in the centre of check cable (or net) in order to increase anchoring force and to reduce pull-out distance, in order to prevent being buried because sediment deposition causes gravity anchor that rear resistance is excessive can't drag of anchor, gravity anchor is placed on the platform of certain altitude, or leaves water stream channel bottom gravity anchor.When ship collision check cable (or net), bow (or stern) will pierce check cable (or going up a check cable in arresting net most) below, drive this check cable (or net) and connected gravity anchor and move to bridge location.Under the tension force effect of check cable (or net), gravity anchor will drag of anchor.Can provide reliable resistance when gravity anchor drags of anchor, its size is approximated to direct ratio with the weight of gravity anchor.The distance that gravity anchor drags of anchor is far away, and the kinetic energy of its consumption is more.Therefore can be according to the tonnage of ship of setting up defences, ship's speed and the concrete conditions such as flow velocity, wind speed, the interaction force of fender system and boats and ships is controlled in certain scope, can not only block boats and ships, the loss that the while also is conducive to alleviate boats and ships.
The invention has the beneficial effects as follows, adopt floating foundation to support check cable (or net), can adapt to better SEA LEVEL VARIATION, be convenient in the profundal zone and be not easy to build fixed basis and build the higher waters use of fixed basic expense, and easily recovering after being subjected to ship collision.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the top view of the present invention when utilizing many bodies floating foundation.
Fig. 2 is the lateral view of the present invention when utilizing many bodies floating foundation.
In figure: 1. elemental floating body, 2. bracing frame, 3. go up check cable, 4. in check cable, 5. descend check cable, 6. connecting strand, 7. gravity anchor, 8. anchor chain (or rope), 9. mooring gravity anchor, 10. mooring anchor chain (or rope).
The specific embodiment
In Fig. 1, floating foundation is made of 3 elemental floating bodies (1), also can by a plurality of or single stability preferably elemental floating body (1) consist of.Bracing frame (2) is arranged on above floating foundation, and the upper check cable (3) of support, middle check cable (4) and lower check cable (5) reach design height.Upper check cable (3), middle check cable (4) and lower check cable (5) connect into arresting net by connecting strand (6).Check cable (the upper check cable (3) in arresting net) to the minimum constructive height of the water surface should be greater than the maximum height of set up defences bow and stern.Lower check cable (5) adjoined water surface.The radical of middle check cable (4) can have many, also can not establish, and needs to require to determine according to blocking.There are anchor chain (or rope) (8) and gravity anchor (7) or gravity anchor group in system at the two ends of check cable (or net), can be also gravity anchor (7) in the centre of check cable (or net) in order to increase anchoring force and to reduce pull-out distance, in order to prevent that rear resistance is excessive can't drag of anchor by being buried because sediment deposition causes gravity anchor (7), gravity anchor is placed in apart from the mud face to be had on the platform of certain altitude, or leaves water stream channel bottom gravity anchor.
Come the ship to from top to bottom in Fig. 1, come the ship to from left to right in Fig. 2, the horizontal projection of upper check cable (3) is in elemental floating body (1) outside, entered before boats and ships bump against floating foundation check cable below.Even boats and ships directly bump against floating foundation and cause the floating foundation displacement, this moment, boats and ships pierced the below of check cable (3), upper check cable (3) will drive gravity anchor (7) under the boats and ships effect mobile, and consume boats and ships kinetic energy in the process of dragging of anchor, and stop ship motion.When ship collision, usually first bump against middle check cable (4) and lower check cable (5), by connecting strand (6), upper check cable (3) is drawn and fall on ship deck, thereby the gravity anchor (7) that drives the arresting net direct bearing drags of anchor, constantly consume boats and ships kinetic energy, finally stop boats and ships to move to bridge location.
For the drift boats and ships that run out of steam, though after clashing into arresting net, speed can descend, at drag force, block under the External Force Acting such as power, boats and ships are understood horizontal turning, and the lateral current power after horizontal turning can be very large.Can't provide enough large anchoring force and boats and ships lateral current active force to balance each other if block facility, boats and ships also can continue to drift about to bridge location.For blocking the lateral drift boats and ships, adopt the strategy of strong upper check cable (3), weak middle check cable (4), lower check cable (5) and connecting strand (6), at the lower check cable of boats and ships lateral current power effect (4), lower check cable (5) or connecting strand (6) with disrumpent feelings, and castle or deck house are usually located at the rear portion of boats and ships, upper check cable (3) will with the boats and ships Upper Structure, boats and ships finally can become vertical state again.
Floating foundation is fixing by mooring anchor chain (10) and mooring gravity anchor (9).The parameters such as the weight of the supporting capacity of the spacing of adjacent floating foundation, check cable (or net), gravity anchor (7) and overall dimensions should be according to the crashproof appropriate design that requires.The quantity of floating foundation is determined according to blocking length and floating foundation distance computation.
In order to reduce the workload that arresting system recovers after ship collision, check cable (or net) is connected 7 with the direct bearing gravity anchor) with bracing frame (2) between be connected a little less than adopting, this connection can be born the active force that wind, wave, stream cause, should connect after ship collision and can disconnect, thereby reset as long as reinstall arresting net when recovering and move gravity anchor (7).
