Incremental launching semi-submersible cross sea landing float bridge

Abstract

The invention provides an incremental launching semi-submersible cross-sea landing floating bridge, belonging to the field of ship marine engineering technique. The floating bridge is assembled by a pushed floating box, a basis floating box and a beachhead floating box which are connected with a tugboat by the buckling between handle retaining blocks and handles. The floating boxes are connected with each other by an underwater transverse joint part and an underwater longitudinal joint part. The floating box is internally provided with inflatable chambers and fixed air chambers. The top end of the inflatable chamber is provided with an electric-controlled deflation valve and an inflation valve is arranged below the left inclined part. The tugboat is provided with a compressor and an electric control unit. When the compressor is started, the inflation valve can be used to inflate the inflation chamber, thus leading the floating bridge to float upwards and facilitating the landing transport. The electric control unit emits the signal and opens the electric-controlled deflation valve so as to lead the inflatable chamber to deflate and the floating bridge to be submerged. The floating bridge has the flexibility of changeable length and width and the concealment of hiding under the water; the floating bridge can move and migrate freely in the horizontal direction and can select the landing point at any points, have wide application range, low manufacturing cost, low cost and quick and convenient assembly.

Description

Technical field: [0001] The invention relates to a sea-crossing landing pontoon, in particular to a push-push semi-submersible cross-sea landing pontoon, which belongs to the technical field of ship ocean engineering. Background technique: [0002] Maritime transportation operations often require a channel connecting ships in the sea and the coast to perform the function of landing and unloading; moreover, a pontoon bridge that can move flexibly and land on the shore by itself is needed. Existing various pontoon bridges do not possess the functions of moving flexibly in horizontal position and voluntarily landing on the shore. In the prior art, the application number is 02268130.2, and the utility model patent named "submersible pontoon bridge" has a structure consisting of a pontoon, a gravity block connector and a gravity block. The block connector is connected with the pontoon, and the gravity block is placed on the riverbed according to the length and width of the ponto...

In the prior art, the application number is 02268130.2, and the utility model patent named "submersible pontoon bridge" has a structure consisting of a pontoon, a gravity block connector and a gravity block. The block connector is connected with the pontoon, and the gravity block is placed on the riverbed according to the length and width of the pontoon equidistantly to position the pontoon below the water surface. It is a device that cannot move the horizontal position and cannot be used flexibly; the application number is 03225689.2 , a utility model patent titled "a kind of submersible floating bridge", the bridge deck is erected on the pier, the pier is fixed on the submersible float, and the submersible float is connected to the stator through a cable or a rigid connection. This patent can reduce the construction of pier in water. engineering, but it is also relatively fixed in horizontal position and difficult to move, and the bridge deck itself is always floating on the water surface, lacking in concealment; the application number is 200310116211.3, and the invention patent named "Convenience Navigation Sea-Crossing Pontoon Bridge" includes floating on the water surface The buoyant joints connected in turn and the anchor blocks sunk at the bottom of the water. The buoyant joints on the pontoon bridge are connected to the navigable pipeline through the bridge in the water. The navigable pipeline has multiple channels, and its longitudinal middle part is sunk and suspended below the water surface. , both ends are exposed to the water and connected to the pontoon bridge, so that vehicles can reach the other shore through the pontoon bridge and the convenient navigation pipeline.
