The discovery of Higgs boson plays a crucial role in understanding the electroweak symmetry breaking sector. From now on, solving the dynamics of this sector needs precision measurements of the couplings of the Higgs boson to the standard model particles. In this work, we investigate the constrains on the anomalous dimension-six operators in the effective Lagrangian couplings, $HWW$ and $HWW\gamma$, through $ep\to \nu H +X$, $\gamma p\to W H +X$ and $e\gamma\to W H \nu$ processes in a high energy envisaged ep collider which is called Large Hadron electron Collider (LHeC). We obtained the best limits on couplings of anomalous $HWW$ and $HWW\gamma$ vertex that $f_{WW}$ about (-0.13, 0.065) in $e\gamma\to W H \nu H$ process and $f_{\varphi}$ about in one of the two intervals (-0.2, 0.2) or (0.65,1) in $ep\to \nu H +X$ at % 95 C.L. with the design luminosity of 10 fb$^{-1}$ and electron beam energy of 140 GeV.
