The invention provides a dam migration device capable of adapting to the water level. The dam migration device comprises a dam passing pipe, ascending pipes, a connecting pipe and a dam lower pipe. A vent valve is arranged at the top of the ascending pipe located at the high position, and vent pipes are arranged at the tops of the other ascending pipes. The vent valve is provided with a reset device, and a linkage device is arranged on a switch of the vent valve and connected with a floater arranged in a dam. According to the migration device, the vent valve is adjusted along with the water level through the floater and the linkage device, so that the water flow speed of a channel is controlled, and the migration device can adapt to automatic adjustment of the water level within the range of 10 meters. The vent pipes are arranged on the ascending pipes, the pressure of the pipes can be kept, and the internal water flow speed is decreased. A retarding channel and a crawling channel are formed in each ascending pipe, and migration of small fishes and crawling migration organisms with poor physical power is facilitated. The device can automatically adapt to changes of the water level in the dam within the range, the water suction pressure is adjusted in a linkage mode, the proper water flow speed is kept, the formed migration channel effect is good, dam protection and migration ecological resource protection are achieved at the same time, and the dam migration device is worthy of application and popularization.
一种可适应水位的大坝洄游装置,包含过坝管、上升管、连接管和坝下管。处于高处的上升管的顶部设有通气阀，其它的上升管的顶部设有通气管，通气阀设有复位装置，通气阀的开关上设有连动装置，连动装置与大坝内设置的浮子连接。本洄游装置通过浮子、连动装置随水位调整通气阀，使通道水流速度得到控制，可适应10米范围的水位自动调整。上升管上设有通气管，可使管道保持压力，减缓内部水流速度。上升管中设有缓速通道和爬行通道，方便体力差的小鱼和爬行类洄游生物洄游。该装置可以在范围内自动适应坝内水位变动，连动调整吸水压力，保持合适的水流速度，形成的洄游通道效果好，兼具保坝和保护洄游生态资源，值得推广运用。
