Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Referring to Fig. 1-8, a kind of closed antifreeze gate has：
Dam body, the dam body back side are equipped with the telescoping cylinder of driving dam body overturning；
Lower shaft is arranged in the bottom of dam body, and lower shaft is the hollow structure for being internally provided with through-hole；
The both ends at the both ends of the lower shaft, closing through-hole are arranged in end cap；
Core is covered, is mounted in the through-hole of lower shaft, set core is the hollow structure for being internally provided with set core centre bore；Set core periphery is set
