[0002] The dam of a reservoir is usually provided with steps extending from the top of the dam to the bottom of the dam. Since the dam of a reservoir is large in scope and high in height, and the number of steps provided on the dam is limited, when an emergency such as drowning occurs, and the accident site is far from the steps, it takes time to reach the accident site via the steps, which is inconvenient for rescue. Therefore, ladders are generally provided on the dam of a reservoir, which play a role in timely rescue in the event of an emergency.

[0003] In the prior art, there is a portable reservoir ladder with announcement number CN219672561U, which includes: a supporting tube and a strap, wherein the strap goes around the outer circumference of the supporting tube, and both ends of the strap extend downward in parallel, a plurality of groups of pedals are evenly arranged vertically on the inner sides of both ends of the strap, and two restraining ropes are arranged in parallel on the outer sides of both ends of the strap, and a locking buckle is arranged above the supporting tube; a plurality of groups of rivet rings are arranged at both ends of the strap corresponding to the pedals to accommodate the ends of the pedals passing through; by arranging the strap in combination with the pedals as a rope ladder, it can be quickly erected and installed on the reservoir dam to guide rescue personnel into the water for rescue, and it is small in size and easy to carry, which can shorten the rescue time and is easy to use.

[0004] However, in the above scheme, when using the ladder, the supporting tube is fixed to the railing with a lock, and then the strap and the pedal are taken out of the supporting tube, and finally the pedals are inserted into the corresponding straps one by one, so as to form a rope ladder structure and complete the erection of the ladder. The process of installing the pedals on the straps is relatively cumbersome and requires a long installation time. Utility Model Content
