我的家乡每逢抗旱打井时,常因泵管掉入井内以及废井内的水泥管子等无法打捞而犯愁。一次.我无意中将拳头塞人一段钢管内,把拳头一张,竟将那段钢管提了起来,由此激发了我的灵感。于是根据这个启示,构思了“内张式深井打捞器”。 Every time my hometown resists drought and drills wells, I often run into trouble because the pump pipe falls into the well and the cement pipe in the waste well cannot be salvaged. Once, I accidentally plugged a fist into a steel tube, put a fist on it, and actually lifted it up, which inspired my inspiration. Based on this revelation, he designed the “inner Zhang deep well salvage device.”
