Solar water heating equipment with good anti-freezing effect suitable for severe cold area

The invention relates to solar water heating equipment with a good anti-freezing effect suitable for a severe cold area. The solar water heating equipment with the good anti-freezing effect suitable for the severe cold area comprises a bottom plate, a water tank and at least two heat collecting pipes; the water tank and the heat collecting pipes are all fixedly connected to the top of the bottom plate; the water tank is cylindrical; the axis of the water tank is parallel to the bottom plate; the heat collecting pipes are uniformly distributed on the water tank along the axis of the water tank;the heat collecting pipes communicate with the water tank and are arranged in an inclined manner; at least two auxiliary mechanisms are arranged on the water tank; the auxiliary mechanisms are in one-to-one correspondence with the heat collecting pipes; two adjusting mechanisms are arranged in each heat collecting pipe; and the adjusting mechanisms are uniformly distributed by taking the axis ofeach heat collecting pipe
