[0002] A dredger is a vessel specially used to maintain the depth and transparency of waters and remove silt and weeds. It is generally made of steel and has a strong output power and suction and discharge capacity. It can remove silt, sediment and other materials, so that the silt and weeds in the waters are kept within a certain depth range for large ships to navigate. In engineering construction, dredgers are used to deepen ports, waterways, rivers and other waters, increase throughput and transportation efficiency, and protect the water environment and ensure water ecological balance.
[0003] However, in the prior art, when a dredging vessel is clearing silt from an area, water in the area may splash, and silt on the bottom of the water may splash onto the pulley along with the detected water source. If the pulley is not cleaned in time, the splashing water droplets and silt may cause the pulley to rust. At the same time, the silt may affect the coordination between the pulley and the traction rope, causing the traction rope to detach from the pulley. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1-3 The pulley assembly of the dredging ship includes a mounting seat 1, a slide groove 5 is provided on the lower end surface of the mounting seat 1, a limiting device is provided in the slide groove 5, a mounting frame 2 is symmetrically provided on the lower end surface of the mounting seat 1, a pulley is connected between the two mounting frames 2 through a rotating shaft, and the output end of the limiting device is in contact with the pulley, a mounting plate 4 is commonly connected to the lower end surfaces of the two mounting frames 2, a moving groove 9 is provided on one side of the mounting plate 4, a limiting groove 10 is provided on the upper end surface of the mounting plate 4, and the limiting groove 10 is connected with the moving groove 9, a cleaning device is provided in the limiting groove 10, and the output end of the cleaning device is in contact with the pulley, and the output end of the cleaning device is slidably carded in the moving groove 9.
[0022] The limiting device includes a threaded rod 6, and the threaded rod 6 is installed in the slide groove 5 through a bearing. One end of the threaded rod 6 passes through the slide groove 5 and extends outward to be installed with a motor 3, and the motor 3 is fixedly installed on one side of the mounting seat 1. The threaded rod 6 is threadedly connected with a slider 7, and the slider 7 is slidably clamped in the slide groove 5, and a limiting plate 8 is provided on the lower end surface of the slider 7.
[0023] A protective groove is provided on the inner wall of the limiting plate 8 .
[0024] The cleaning device includes a spring 11, and the spring 11 is fixedly connected in the limiting groove 10, one end of the spring 11 is fixedly connected to a fixing rod 12, a pressure plate 14 is fixedly connected to the outer wall of the fixing rod 12, and the pressure plate 14 is slidably clamped in the movable groove 9, and a cleaning plate 13 is fixedly installed on one end of the fixing rod 12 away from the spring 11, and the cleaning plate 13 is in contact with the pulley.
[0025] The inner wall of the cleaning plate 13 is polished, and the inner walls on both sides of the cleaning plate 13 are inclined. It should be noted that such a design can ensure that both sides of the cleaning plate 13 can clean the outer wall of the pulley.
[0026] The diameter of the fixing rod 12 is smaller than the diameter of the limiting groove 10 . It should be noted that such a design can ensure that the fixing rod 12 can slide in the limiting groove 10 .
[0027] When the utility model is in use, the pull rope can be first passed through the pulley, and then the motor 3 is started. The output shaft of the motor 3 drives the threaded rod 6 to rotate, and then the threaded rod 6 drives the threaded slider 7 to slide in the slide groove 5. At this time, the limit plate 8 will move with the slider 7 until the limit plate 8 slides to the top of the pulley.
[0028] When the pulley rotates, the cleaning plate 13 will clean the groove on the outer wall of the pulley. Because the pulley will generate friction with the cleaning plate 13 when rotating, the cleaning plate 13 will be worn after a long period of friction. The fixing rod 12 can drive the cleaning plate 13 to always contact the pulley through the spring 11 until the cleaning plate 13 needs to be replaced. By pressing the pressing plate 14, the fixing rod 12 can compress the spring 11 downward. At this time, the fixing rod 12 will drive the cleaning plate 13 to disengage from the pulley, and the cleaning plate 13 can be replaced.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
