[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the "one embodiment" or "embodiments" referred to herein are intended to encompass a particular feature, structure, or characteristic in at least one implementation of the present application. The appearances of the "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive.

[0031] Embodiment 1

[0032] With reference to Figures 1-9 For the first embodiment of the present application, the embodiment provides a high-efficiency dredging cutter suction dredger, which comprises a main body assembly 100, including a platform 101, the platform 101 is provided with positioning piles 102, and the positioning piles 102 are fixed with lifting mechanisms 103 on one side.

[0033] The platform 101 is a carrier of the entire dredging ship equipment and operation area, and the number of the positioning piles 102 is two, which are symmetrically distributed on the platform 101. The positioning piles 102 are used to stably fix the dredging ship on the riverbed before the dredging ship works, and are the basic guarantee for accurate positioning and stable operation of the dredging ship. When the dredging ship reaches the designated working area, the positioning piles 102 are lowered and inserted into the riverbed, so as to make the ship body stable as a fulcrum, resist the influence of external forces such as water flow and waves on the ship body, ensure that the ship body does not displace or shake during dredging, provide a stable working platform for the dredging equipment such as the cutter suction device, and ensure that the dredging operation can be carried out according to the predetermined accuracy and range, thereby improving the accuracy and quality of the dredging work. The lifting mechanism 103 is used to control the lifting of the positioning pile 102, which is the prior art, and the working principle of the present scheme will not be described in detail, and the person skilled in the art can clearly understand the working principle.

[0034] The stabilizing assembly 200 is arranged on the platform 101 and comprises a connecting block 201 fixed to the top of the positioning pile 102. The connecting block 201 can be driven to move synchronously with the lifting of the positioning pile 102. The positioning pile 102 is provided with a stabilizing piece 202 on one side. The stabilizing piece 202 is arranged to improve the stability of the positioning pile 102 during lifting, thereby improving the accuracy of positioning and prolonging the service life of the positioning pile 102. The platform 101 is fixed with a moving piece 203, which is used to reduce the space occupied by the stabilizing piece 202 in the working area of the dredging ship, so as to avoid the space interference caused by the sand dredging and other operation links of the dredging ship after positioning is completed. One positioning pile 102 corresponds to two groups of stabilizing pieces 202 and moving pieces 203.

[0035] The stabilizer 202 comprises a winch 202a, a steel wire rope 202b is wound on the winch 202a, a sliding groove 201-1 is formed on the connecting block 201, a sliding block 202c is arranged in the sliding groove 201-1, the sliding block 202c is movably connected with one end of the steel wire rope 202b, a first spring 202d is fixed at one end of the sliding block 202c, and the other end of the first spring 202d is fixed with the inner wall of the sliding groove 201-1.

[0036] The motor in the winch 202a and the motor of the lifting mechanism 103 can be synchronously switched, which is prior art, and the working principle is clear to those skilled in the art, and the speed of the two motors is set, so that the winch 202a can be synchronized to wind and release when the lifting mechanism 103 operates to lift the positioning pile 102, and the steel wire rope 202b is always in a tight state. Since the positioning pile 102 is arranged on both sides of the positioning pile 102, under the action of the two steel wire ropes 202b, the positioning pile 102 can stably move up and down, and the steel wire rope 202b shares part of the load of the positioning pile 102 in the lifting process. Especially for the long positioning pile 102, the bending moment and shear force generated by its own gravity and external force are reduced, the internal stress level of the positioning pile 102 structure is reduced, thereby significantly prolonging the service life of the positioning pile 102 and improving the reliability of the entire positioning system.

[0037] The first spring 202d is a high-strength spring and is used for buffering. When the positioning pile 102 is impacted by external force or vibrates during lifting, the steel wire rope 202b will transmit the force to the first spring 202d. The first spring 202d absorbs and buffers the force by elastic deformation, converts kinetic energy into elastic potential energy, and then releases the elastic potential energy after the force disappears, so that the relative position of the steel wire rope 202b and the positioning pile 102 returns to the equilibrium state, thereby reducing the impact of the impact force on the connecting part, effectively absorbing the excessive tension generated by the instantaneous force change of the positioning pile 102, avoiding damage to the steel wire rope 202b due to bearing overload tension, prolonging the service life of the steel wire rope 202b, and the sliding block 202c is externally fixed with a connecting ring, and one end of the steel wire rope 202b is connected with the sliding block 202c through the connecting ring.

[0038] Embodiment 2

[0039] Reference Figures 1-9 This is the second embodiment of the utility model, and the embodiment is based on the previous embodiment.

[0040] Specifically, the moving piece 203 includes a fixed block 203a fixed on the platform 101, a sliding groove 203a-1 is formed in the fixed block 203a, a moving block 203b is arranged in the sliding groove 203a-1, the moving block 203b slides in the sliding groove 203a-1, so as to change the relative position of the moving block 203b and the positioning pile 102, the moving block 203b is fixed with a supporting block 203f, the bottom of the winch 202a is fixed with the supporting block 203f, so as to stably connect the winch 202a and the moving block 203b, when the moving block 203b moves, the winch 202a can move synchronously.

[0041] Specifically, the winch 202a is provided with a first disc 203c on one side, the first disc 203c is fixed with a rotating block 203d, a first through groove 203a-2 is formed in the fixed block 203a, and a rack 203e is fixed in the first through groove 203a-2.

[0042] When the positioning pile 102 moves downward for positioning, the winch 202a is started synchronously, the first disc 203c will rotate synchronously, and then drive the rotating block 203d to rotate synchronously, the first through groove 203a-2 is located in the same plane with the first disc 203c and the rotating block 203d, so when the rotating block 203d rotates, the rotating block 203d can rotate into the first through groove 203a-2, a plurality of tooth blocks are fixed on the rack 203e, adjacent tooth blocks have a large distance, and the length of the tooth blocks and the rotating block 203d is relatively long, when the rotating block 203d rotates to the position of contacting the tooth blocks on the rack 203e, the tooth blocks hinder the rotating block 203d from rotating, but at this time the winch 202a is still running, so that the first disc 203c and the winch 202a relatively fixed to the fixed block 203a move to the direction close to the positioning pile 102, when the tooth blocks are separated from the rotating block 203d, the winch 202a continues to drive the first disc 203c to rotate, but at this time the two will not move to the direction of the positioning pile 102, until the winding drum of the winch 202a rotates one circle, then it will move a small distance again.

[0043] When the positioning pile 102 descends to the lowest position, the distance between the winch 202a and the positioning pile 102 is the smallest at this time, so that when the positioning is completed, the space occupied by the steel wire rope 202b and the winch 202a on the platform 101 is reduced, so as to avoid affecting the subsequent dredging work.

[0044] When the positioning pile 102 rises to the highest position, the distance between the winch 202a and the positioning pile 102 is the largest, so as to avoid that the positioning pile 102 shakes greatly.

[0045] Specifically, the stabilizing assembly 200 further comprises a locking member 204 arranged in the fixed block 203a, the locking member 204 is arranged for locking the relative position of the moving block 203b in the sliding groove 203a-1, and ensuring that the position of the winch 202a does not change after the positioning pile 102 stops lifting, so that the steel wire rope 202b is always in a tight state, thereby improving the stability of positioning.

[0046] The locking member 204 comprises a second disc 204a arranged on one side of the first disc 203c, the fixed block 203a is provided with a second through groove 203a-3, the second disc 204a is movable in the second through groove 203a-3, and the second disc 204a is fixed with a protruding block 204b, and the protruding block 204b is in a fan shape.

[0047] When the winch 202a is started, the second disc 204a is driven to rotate synchronously, thereby driving the protruding block 204b to rotate.

[0048] Specifically, the fixed block 203a is provided with a moving groove 203a-4, the moving groove 203a-4 is provided with a locking block 204c, one side of the locking block 204c is fixed with a second spring 204d, the other end of the second spring 204d is fixed with the inner wall of the moving groove 203a-4, the second spring 204d provides a continuous pushing force for the locking block 204c, so that the end surface of the locking block 204c is located in the sliding groove 203a-1, and the number of the locking blocks 204c is more than one.

[0049] Specifically, the moving block 203b is provided with a locking groove 203b-1, the locking groove 203b-1 is clamped with the locking block 204c, and the two are clamped, so that the position of the moving block 203b in the sliding groove 203a-1 is locked, and when the two are not in the clamped state, the moving block 203b can slide in the sliding groove 203a-1 at will.

[0050] Embodiment 3

[0051] Refer to Figures 1-9 For the third embodiment of the utility model, the embodiment is based on the first two embodiments.

[0052] Specifically, the locking block 204c is provided with an inclined groove 201c-1, the protruding block 204b has an inclined surface 204b-1, and the inclined surface 204b-1 can be in contact with the inclined groove 201c-1.

[0053] When the winch 202a starts to drive the second disc 204a and the protrusion 204b to rotate, with the rotation of the protrusion 204b, the inclined surface 204b-1 of the protrusion 204b will press the inclined groove 201c-1, so that the second spring 204d is compressed, the locking block 204c is separated from the locking groove 203b-1, and at this time the moving block 203b can move. With the rotation of the protrusion 204b, when the inclined surface 204b-1 of the protrusion 204b is separated from the inclined groove 201c-1, and the locking block 204c and the locking groove 203b-1 are again coaxial, the two are engaged again, thereby limiting the movement of the moving block 203b.

[0054] Specifically, the protrusion 204b has a symmetrical structure, and the rotating block 203d also has a symmetrical structure. The part of the protrusion 204b close to the symmetry axis has a longer length, and the part away from the symmetry axis has a shorter length.

[0055] With the rotation of the protrusion 204b, the shorter part of the protrusion 204b will first approach the inclined groove 201c-1 and leave a small gap between the protrusion 204b and the inclined groove 201c-1. With the further rotation of the protrusion 204b, the length of the protrusion 204b gradually increases, the distance between the protrusion 204b and the inclined groove 201c-1 gradually decreases, and the protrusion 204b contacts the inclined groove 201c-1. Then the protrusion 204b presses the inclined groove 201c-1, so that the second spring 204d is compressed, the locking block 204c is separated from the locking groove 203b-1, and the protrusion 204b continues to rotate. When the inclined surface 204b-1 of the protrusion 204b is separated from the inclined groove 201c-1, the second spring 204d recovers and exerts a pushing force on the locking block 204c.

[0056] By setting the relative position of the rotating block 203d and the protrusion 204b as shown in the figure, the symmetry axes of the two are parallel, so that the same process can be realized in both directions of rotation of the winch 202a.

[0057] When the winch 202a rotates, the inclined surface 204b-1 of the protrusion 204b first contacts the inclined groove 201c-1, so that the locking block 204c is separated from the locking groove 203b-1, and the locking of the moving block 203b is released. Then the rotating block 203d contacts the tooth block on the rack 203e, so that the moving block 203b moves a small distance in the sliding groove 203a-1. When the rotating block 203d is separated from the tooth block on the rack 203e, the moving block 203b moves a small distance, and the locking groove 203b-1 on the moving block 203b is again coaxial with the locking block 204c. Under the action of the second spring 204d, the two are engaged again, locking the position of the moving block 203b.

[0058] Specifically, the winch 202a includes a reel 202a-1, and the first disc 203c and the second disc 204a are fixed to the reel 202a-1.

[0059] The motor of the winch 202a drives the reel 202a-1 to rotate, the winding drum on the reel 202a-1 rotates, and the steel wire rope 202b is wound or unwound, and the reel 202a-1 drives the first disc 203c and the second disc 204a to rotate synchronously.

[0060] Specifically, the main body assembly 100 further comprises a dredging mechanism 104, which is movably connected with the platform 101. The dredging mechanism 104 directly acts on the soil at the bottom of the water through various dredging devices such as a reamer, a grab bucket, and a shovel, and excavates the soil from the riverbed or the seabed. This is the prior art, and the present scheme will not be described in detail, and those skilled in the art can clearly understand the working principle.

[0061] In use, the lifting mechanism 103 is started to move the positioning pile 102 downward to fix the position of the ship body. At this time, the winch 202a is started synchronously to wind the steel wire rope 202b. The steel wire rope 202b is always taut, and shares part of the load borne by the positioning pile 102 in the lifting process, thereby reducing the bending moment and shear force generated by the self-gravity and external force of the positioning pile 102, prolonging the service life of the positioning pile 102, and improving the reliability of the entire positioning system.

[0062] The winch 202a also drives the second disc 204a and the protrusion 204b to rotate. The shorter part of the protrusion 204b will first approach the chute 201c-1 and leave a very small gap with the chute 201c-1. The protrusion 204b is further rotated, the length of the protrusion 204b gradually increases, the distance between the protrusion 204b and the chute 201c-1 decreases, and the protrusion 204b contacts the chute 201c-1. Then, the protrusion 204b extrudes the chute 201c-1, so that the second spring 204d is compressed, the locking block 204c is separated from the locking groove 203b-1, and the protrusion 204b continues to rotate. When the inclined surface 204b-1 of the protrusion 204b is separated from the chute 201c-1, the second spring 204d recovers and exerts a pushing force on the locking block 204c.

[0063] At the same time, the winch 202a drives the first disc 203c to rotate. When the rotating block 203d rotates to a position where it contacts the tooth block on the rack 203e, the tooth block hinders the rotation of the rotating block 203d. However, at this time, the winch 202a is still running, so that the first disc 203c moves a small distance in the direction of approaching the positioning pile 102 relative to the fixed block 203a of the winch 202a, which is just enough to make the locking groove 203b-1 on the moving block 203b again coaxial with the locking block 204c. Under the action of the second spring 204d, the two are engaged again to lock the position of the moving block 203b.

[0064] With the lowering of the positioning pile 102, this process will continue until the positioning pile 102 stops moving and ensures that the locking groove 203b-1 is engaged with the locking block 204c, locking the moving block 203b position, at this time the distance between the winch 202a and the positioning pile 102 is the smallest, so as to reduce the space occupied by the steel wire rope 202b and the winch 202a on the platform 101 after the positioning is completed, thereby avoiding affecting the subsequent dredging work.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
