[0020] Through those skilled in the art, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of the electrical components working successively in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0021] Embodiment: When the two boats are at a certain distance, the two hydraulic winches 10 work simultaneously to adjust the optimal angle. When they are at the right distance, the hydraulic telescopic rod 12 extends into the tail of the front boat. When the two boats are completely close, the electromagnet is controlled by the travel switch to work, and at the same time, the wireless transmission signal 19 is started for the general command to receive.

After the connection of the two boats is completed, when laying the pontoon bridge 2 at night, the infrared catcher 17 at the bow of the pontoon bridge 2 catches the infrared sensor 18 at the tail of the pontoon bridge 2. When the two pontoon bridges 2 approach, at a certain distance, the two hydraulic winches 10 work to pull the two boats closer and adjust the optimal angle, reducing the manual labor and saving a large amount of manpower and material resources, improving the installation efficiency of the pontoon bridge and saving the installation time.
