[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a hydraulic system of a cutter-suction dredger. The hydraulic system of the cutter-suction dredger includes a main body component 100 and a lifting component 200, and the cooperation of the two can facilitate maintenance personnel to carry out repairs and replacements.

[0027] The main assembly 100 includes a hydraulic pump 101 , an air outlet pipe 102 and a base 103 . The air outlet pipe 102 is fixed to one side of the hydraulic pump 101 , and the base 103 is fixed to the bottom of the hydraulic pump 101 .

[0028] The hydraulic pump 101 converts the mechanical energy input by the engine into liquid pressure energy. This energy conversion device plays a vital role in the hydraulic transmission system, providing the system with necessary pressure oil, thereby driving various hydraulic equipment of the cutter suction dredger to work. The outlet pipe 102 is used to discharge the gas inside the system to prevent the gas from accumulating in the system and affecting the normal operation of the hydraulic system. The base 103 is used to support the hydraulic pump 101 to prevent the hydraulic pump 101 from deflecting. A filter is arranged on the top of the outlet pipe 102. The filter can effectively prevent dust, particles or other impurities in the air from entering the hydraulic system. If these impurities enter the system, they may cause wear, blockage or damage to the pump, valve or other hydraulic components, thereby affecting the performance and stability of the entire hydraulic system.

[0029] The lifting assembly 200 is disposed on the hydraulic pump 101 and includes a lifting member 201 , a cleaning member 202 and a driving member 203 . The lifting member 201 is located at the bottom of the hydraulic pump 101 , the cleaning member 202 is disposed on the air outlet pipe 102 , and the driving member 203 is located on the cleaning member 202 .

[0030] The height of the hydraulic pump 101 can be adjusted by the setting of the lifting member 201, which can facilitate maintenance personnel to carry out repairs and replacements. When the hydraulic pump needs to be maintained, the height of the hydraulic pump can be adjusted to make it easier to approach and operate, thereby improving maintenance efficiency. The lifting member 201 can be driven to move by the setting of the driving member 203. While driving the lifting member 201 to move, the driving member 203 also drives the cleaning member 202 to move, so that the filter net on the top of the outlet pipe 102 can be cleaned to prevent the outlet pipe 102 from being blocked.

[0042] The first fixed block 202c is fixed to one side of the air outlet pipe 102, and the first fixed block 202c is used to support the cleaning brush 202a to prevent the cleaning brush 202a from being offset. The second fixed block 202d is fixed to one side of the hydraulic pump 101, and the second fixed block 202d can be set to support the rotating shaft 202b to prevent the rotating shaft 202b from being offset.

[0043] Specifically, the driving member 203 includes a second gear 203a, a rack 203b and a fixed plate 203c.

[0044] When the rotating rod 201g needs to be rotated, the movement of the rack 203b will drive the second gear 203a to rotate, and the rotation of the second gear 203a will drive the rotating rod 201g to rotate. There are two fixed plates 203c, both of which are fixed to the inner wall of the protective shell 201c. The setting of the fixed plate 203c can support the rack 203b to prevent the rack 203b from deviating.

[0045] Example 3

[0046] Reference Figure 2 and Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0047] Specifically, the driving member 203 further includes a cylinder 203d and a base 203e. The cylinder 203d is fixed to one side of the rack 203b, and the base 203e is fixed to the bottom of the cylinder 203d.

[0048] The rack 203b can be driven to move by the cylinder 203d. The base 203e is fixed to the inner wall of the protective shell 201c. The base 203e is used to support the cylinder 203d to prevent the cylinder 203d from deflecting.

[0049] Specifically, the driving member 203 further includes a rotating sleeve 203f and a driving rod 203g. The rotating sleeve 203f is fixed to the bottom of the rotating shaft 202b. The driving rod 203g is inserted into the bottom of the rotating sleeve 203f. The driving rod 203g and the rotating sleeve 203f are movably connected.

[0050] A rotation groove corresponding to the driving rod 203g is provided in the rotating sleeve 203f. When the driving rod 203g moves in the rotating sleeve 203f, it drives the rotating sleeve 203f to rotate. At this time, the rotation of the rotating sleeve 203f can drive the rotating shaft 202b to rotate.

[0051] Specifically, the driving member 203 further includes a moving block 203h and a pressing block 203i. The moving block 203h is fixed to the bottom of the driving rod 203g, and the pressing block 203i is fixed to one end of the rack 203b.

[0052] When the rack 203b moves, it will drive the squeezing block 203i to move. The movement of the squeezing block 203i will squeeze the moving block 203h to make the moving block 203h rise. At this time, the movement of the moving block 203h can drive the driving rod 203g to move in the rotating sleeve 203f.

The movement of the lifting rod 201a can drive the base 103 to move. When the base 103 moves, it will drive the support rod 201d to move. At this time, the movement of the support rod 201d can support the base 103 to prevent the base 103 from deviating during movement. The height of the hydraulic pump 101 can be adjusted by the movement of the base 103.

[0054] While adjusting the height of the hydraulic pump 101, the rack 203b will drive the extrusion block 203i to move when it moves. The movement of the extrusion block 203i will squeeze the moving block 203h to make the moving block 203h rise. At this time, the movement of the moving block 203h can drive the driving rod 203g to move in the rotating sleeve 203f. When the driving rod 203g moves in the rotating sleeve 203f, it will drive the rotating sleeve 203f to rotate. At this time, the rotation of the rotating sleeve 203f can drive the rotating shaft 202b to rotate. The rotation of the rotating shaft 202b will drive the cleaning brush 202a to rotate. At this time, the filter net can be cleaned by the rotation of the cleaning brush 202a.
