The invention relates to a clearing device, in particular to a moss clearing device for a water inlet pipe mesh enclosure in an aquaculture pond. The technical problem of the invention is to provide the moss clearing device for the water inlet pipe mesh enclosure in the aquaculture pond, which does not require people to go down into water, finds the position of the water inlet pipe in a short time, and can prevent water plants from enwinding equipment. The technical embodiment of the invention is as follows: the moss clearing device for the water inlet pipe mesh enclosure in the aquaculture pond comprises a sliding rail, sliding blocks, a mounting frame, a clearing mechanism, clamping blocks, a rack, a gear, a hand compression bar and the like, wherein clamping grooves are formed in the upper side and lower side of the left part of the sliding rail. The moss clearing device does not require people to go down into water for clearing through the arranged clearing mechanism, is beneficialto the physical and psychological health of people and has a relatively good clearing effect; the sliding blocks and the sliding rail are arranged, and when the sliding blocks move to the lower end of the sliding rail, first guide rods at the upper and lower sides are all clamped in the clamping slots, and the clearing mechanism just moves to the left side of the water inlet pipe, and then can clear moss; and the time of finding the position of the water inlet pipe is relatively short.
