Given vectors $\overrightarrow{m}=(\sqrt{3}\sin \omega x,1)$, $\overrightarrow{n}=({\cos }^{2}\omega x+1)$, let the function $f(x)= \overrightarrow{m}\cdot \overrightarrow{n} +b$.  
(Ⅰ) If the graph of the function $f(x)$ is symmetric about the line $x= \frac{\pi}{6}$, and $\omega\in[0,3]$ when, find the intervals of increase for the function $f(x)$.  
(Ⅱ) Under the condition of (Ⅰ), when $x\in[0, \frac{7\pi}{12}]$, the function $f(x)$ has exactly one zero point, find the range of the real number $b$.
