Sinking and floating type port safety gate

Abstract

The invention relates to a sinking and floating type port safety gate. The safety gate comprises two opposite port dams, and further comprises at least two sets of traction devices; a shore side guidewheel is arranged on each port dam; a mooring rope penetrates between the two shore side guide wheels; the end parts of the mooring rope are wound around the shore-side guide wheels and then are vertically downward; at least one counterweight block is connected to each of the two ends of the mooring rope; a plurality of floating bodies capable of enabling the mooring rope to float on the water surface are connected to the part, located between the two shore side guide wheels, of the mooring rope in a penetrating mode; each traction device comprises a winch, an underwater guide wheel and a traction rope; one ends of the traction ropes are connected to the winches; the other ends of the traction ropes penetrate through the underwater guide wheels and then are tied on the mooring rope or thefloating bodies; the distance between the traction ropes of the two sets of traction devices on the mooring rope or the floating bodies is not smaller than the width of a ship; and the traction ropesare taken up through the winches so that the mooring rope can be placed underwater so as to ensure the ship to pass through. The safety gate has the advantage that the port safety can be realized byopening and closing the safety gate.

Description

technical field [0001] The invention belongs to the technical field of port safety protection, and in particular relates to a port safety door composed of floating body components capable of sinking and floating on the water surface and underwater. Background technique [0002] In the prior art, large and small ships are all berthed in the port, but most of the entrances of domestic ports are open without safety protection devices, so the ships docked in the port are vulnerable to foreign lawlessness. The invasion of merchant ships poses a huge security risk. In addition, because the water surface area of ​​the port is relatively open, the length is generally more than 100 meters, or even hundreds of meters, and the marine climate conditions are harsh, which brings great difficulties to the installation of isolation protection devices in the water surface area of ​​the port. [0003] The safety of the port is in urgent need of a safety protection door that can be opened and...
