[0024] With reference to Figure 1 And Figure 4The scraping assembly comprises a connecting rod 19 fixedly connected to one side of the front upper rod 14 and the rear upper rod 13, one side of the connecting rod 19 is connected with a scraper 16 in contact with the upper surface of the guide rail 1, and one side of the scraper 16 is fixedly connected with a triangular pyramid 17 in contact with the upper surface of the guide rail 1. Through the scraper 16 and the triangular pyramid 17, the seaweed and plankton adsorbed on the guide rail 1 can be cleaned during the movement of the track trolley on the guide rail 1, preventing the normal operation of the track trolley and improving the stability of the track trolley. The scraper 16 and the triangular pyramid 17 are arranged at the front and rear of the track trolley, so that the seaweed and plankton can be cleaned when the track trolley moves forward or backward on the guide rail 1, improving the practicability of the track trolley. The triangular pyramid 17 can push the seaweed and plankton out of the guide rail 1 without damaging them, preventing the damaged seaweed and plankton from accumulating on the upper side of the guide rail 1 and the subsequent personnel from cleaning. The seaweed and plankton are pushed back into the river or the ocean, protecting the ecological environment. The scraper 16 and the connecting rod 19 are connected with an adjusting bolt 20, which can adjust the distance between the scraper 16, the triangular pyramid 17 and the upper surface of the guide rail 1, facilitating the scraping of seaweed and plankton according to the actual environment.
