The invention discloses a trigger type dust removal vehicle for environment governance, relates to the technical field of environment, and mainly aims to solve the problem that a traditional dust removal vehicle needs to use a pump machine, so that limitation is caused. The dust removal vehicle comprises a base, a water tank is fixed to the top of the base, the bottom of one side of the water tankis connected with the base through a supporting frame in a rotating manner, a propping plate is fixed in the middle of the other side of the water tank, a jacking assembly capable of lifting the propping plate is arranged below the propping plate, a water outlet channel is formed in the part, on the same side of the supporting frame, of a tank body of the water tank, the water outlet channel is in an inverted U shape, and a water inlet end of the water outlet channel is higher than a water outlet end. According to the trigger type dust removal vehicle for environment governance, the water tank one end of which is rotationally connected is arranged, and the water outlet channel capable of forming a siphon is formed in the water tank so that the siphon effect can be triggered by inclining the water tank during use, then the water flow can be generated under the condition that the pump machine is not needed, the overall use limitation is greatly reduced, and compared with the traditionaldust removal vehicle, the dust removal vehicle has great improvement.
