The utility model discloses a field sampling solution collecting appliance for measurement on the contamination degree of a power grid. The appliance comprises a mounting plate, a funnel stand, a funnel, a solution collecting bottle, and bolts. By adopting the appliance, the problem that the collection of a sampling solution is incomplete because of loss of part of a contaminated cleaning solution in the field sampling and collecting processes of the contaminated solution during the measurement on the contamination degree of the power grid, so that the deviation in evaluation of the contamination degree is caused is solved; and the field sampling solution collecting appliance is novel and appropriate in combination, convenient to use, simple to manufacture and low in price, and is especially applicable to the field collection operation of the contaminated sampling solution in the measurement on the contamination degree of the power grid.
