Description

Drum-type elastic ship navigation tunnel channel anti-collision side wall device Technical Field The utility model relates to the technical field of ship anti-collision, in particular to a roller type elastic ship navigation tunnel channel anti-collision side wall device. Background The ship navigation tunnel is an important and novel ship passing facility in development of a high-head cascade water transportation channel of a high mountain gorge river, is used as a very special semi-closed shallow water narrow water channel, is greatly different from the conventional limited water area navigation, has a width which is only 1-2 meters larger than the width of a ship, and has the advantages of limited channel depth, small margin depth, smaller tunnel section coefficient and large ship operation difficulty due to the influence of channel bank wall effect and bottom suction effect. The prior navigation tunnel has the defects that the side wall of the navigation channel adopts a general reinforced concrete structure, the rigidity is high, but the side wall of the navigation channel is damaged due to frequent deflection and rubbing in the navigation process of the ship, and even collapse is possibly caused by collision, so that the navigation safety of the ship and the structural stability of the tunnel are greatly influenced. Therefore, it is necessary to develop a novel device which is applicable to the navigation environment characteristics of the water tunnel and can effectively provide protection for the navigation safety of ships and the safety of the side wall structure of the navigation groove. Disclosure of utility model The utility model aims to provide a roller-type elastic ship navigation tunnel gutter anti-collision side wall device, which aims to solve the problems that the side wall of a gutter is damaged due to frequent deflection and rubbing during the ship navigation process, and even collapse is possibly caused by collision, so that the ship navigation safety and the structural stability of a tunnel are greatly influenced. In order to achieve the above purpose, the utility model provides a drum-type elastic ship navigation tunnel channel anti-collision side wall device, which comprises a wall body, a stay bar, a string rod, a spring sleeve, a damping spring, a pressing plate and an anti-collision roller, wherein the wall body is provided with a mounting groove, the spring sleeve is detachably connected with the wall body and is positioned on the inner side wall of the mounting groove, the pressing plate is slidably connected with the spring sleeve and is positioned on the inner side wall of the spring sleeve, the stay bar is fixedly connected with the pressing plate and is positioned on one side of the pressing plate, the stay bar is slidably matched with the spring sleeve, the string rod is fixedly connected with the stay bar and is positioned at one end of the stay bar, one end of the damping spring is fixedly connected with the pressing plate and is positioned on one side of the pressing plate, the other end of the damping spring is fixedly connected with the spring sleeve and is positioned on the inner side wall of the spring sleeve, and the anti-collision roller is rotatably connected with the string rod and is positioned on the outer side wall of the string rod.
