The method for operating the floating steering and anti-collision device for navigation wall section ships entering and exiting a lock as claimed in any one of claims 1 to 9, characterized in that it comprises the following steps: 步骤1，浮式调向防撞单元的安装：Step 1: Installation of floating steering and anti-collision unit: 采用吊装设备，将通过连杆（25）组装连接之后的浮筒（20）和浮筒支架主体（12）整体吊装放入到导航墙闸墙（28），并保证支架导向轮组和浮筒导向轮组与闸墙导轨（29）构成滑动导向配合；Using a lifting device, the buoy (20) and the buoy bracket body (12) assembled and connected by the connecting rod (25) are hoisted as a whole and placed into the navigation wall gate wall (28), and it is ensured that the bracket guide wheel group and the buoy guide wheel group form a sliding guide fit with the gate wall guide rail (29); 步骤2，浮式调向防撞单元的浮动升降：Step 2: Floating and lifting of the floating direction adjustment and anti-collision unit: 待整个浮式调向防撞单元安装布置完成之后，浮筒（20）在水的浮力作用下，使整个浮式调向防撞单元与水面相对位置保持不变；支架导向轮组和浮筒导向轮组用于克服与闸墙导轨（29）的摩擦力，保证上下移动顺畅；After the entire floating direction-adjusting and anti-collision unit is installed and arranged, the buoy (20) maintains the relative position of the entire floating direction-adjusting and anti-collision unit to the water surface under the buoyancy of the water; the bracket guide wheel group and the buoy guide wheel group are used to overcome the friction with the gate wall guide rail (29) to ensure smooth up and down movement; 步骤3，船舶的防撞：Step 3, ship collision avoidance: 当船舶在闸室内部航行，在受到水流不稳定冲击，撞向闸墙时，船舶将首先撞向橡胶护舷主体（1），此时橡胶护舷主体（1）利用橡胶挤压吸能，缓冲撞击力，降低碰撞噪音和震动，保护导航墙水工结构和船舶自身不受破坏；When a ship is sailing inside the lock chamber and is impacted by unstable water flow and collides with the lock wall, the ship will first collide with the rubber fender body (1). At this time, the rubber fender body (1) absorbs energy by rubber extrusion, buffers the impact force, reduces collision noise and vibration, and protects the navigation wall hydraulic structure and the ship itself from damage; 同时橡胶护舷主体（1）将同步的将冲击传递给弹性缓冲机构，弹性缓冲机构将会被压缩，吸收船舶撞击或挤靠能量；At the same time, the rubber fender body (1) will synchronously transmit the impact to the elastic buffer mechanism, and the elastic buffer mechanism will be compressed to absorb the energy of the ship's collision or squeezing; 步骤4，船舶位置的恢复：Step 4, recovery of ship position: 在船舶撞击橡胶护舷主体（1）之后，在弹性缓冲机构压缩缓冲效果下，船舶速度逐渐降为0后，弹性缓冲机构慢慢恢复，释放能量，将橡胶护舷主体（1）向外推，从而将力以柔和的方式作用于船舶，使斜跨引航道的船舶摆正方向；After the ship hits the rubber fender body (1), under the compression and buffering effect of the elastic buffer mechanism, the ship speed gradually drops to 0, and the elastic buffer mechanism slowly recovers, releasing energy and pushing the rubber fender body (1) outward, thereby applying force to the ship in a gentle manner, so that the ship diagonally crossing the pilot channel can be straightened; 步骤5，浮式调向防撞单元的更换：Step 5: Replacement of the floating steering and anti-collision unit: 当防撞装置出现损坏时，通过安装在浮筒支架主体（12）上的吊耳将防撞装置整体吊出，采用备用件换新后，整体运回场内进行检修，以缩短停航检修时间，降低对通航的影响。When the anti-collision device is damaged, the anti-collision device is hoisted out as a whole through the lifting lugs installed on the buoy support body (12), and after being replaced with spare parts, the device is transported back to the yard for maintenance, so as to shorten the suspension maintenance time and reduce the impact on navigation.
