Description

Technical Field

[0001] The invention relates to the technical field of marine engineering ship equipment, and in particular to a shallow water planing ship with a swinging cutter head and a control method thereof. Background Art

[0002] When ships are under construction at sea, the corresponding offshore structures are sometimes distributed in a straight line with a length of hundreds of meters. When the construction ship approaches the construction site, the structures become obstacles instead, and it is difficult to anchor to one side. The hull cannot use the bow and stern "figure eight anchors" to resist environmental loads such as wind, waves, and currents that may come from all directions at sea. Even if a small angle is forcibly adopted for anchoring, the hull's lateral positioning ability is very weak. The hull is subject to lateral environmental loads and is easily offset and collides with buildings during the construction process.

[0003] If thrusters are used for dynamic positioning, the main drawbacks include but are not limited to: high cost, low positioning reliability, and the dilemma of not being able to work in shallow water, which cannot solve the above problems well. Installing positioning piles on the ship can only solve the problem of stationary position, but cannot solve the problem of ship position control during ship movement. Therefore, a shallow water planing construction ship and its control method are needed. Summary of the invention

[0034] like Figure 1-Figure 7 As shown, the present invention provides a shallow water planing boat with a swinging blade head, comprising a hull 100, a connecting frame 200, a sliding shoe mechanism 300, and a plurality of anchoring mechanisms 400, wherein the anchoring mechanisms 400 are arranged at the head and tail of the hull 100, the connecting frame 200 is hinged on the hull 100, and the sliding shoe mechanism 300 is arranged at one end of the connecting frame 200 away from the hull 100; the sliding shoe mechanism 300 comprises a main blade assembly and a swinging blade head assembly 320, and the main blade assembly comprises a main sliding blade 311 And the sliding shoe 310, the main sliding knife 311 is fixedly arranged at the bottom of the sliding shoe 310, a hinge is arranged between the sliding shoe 310 and the connecting frame 200, and the sliding shoe 310 is hinged in the vertical direction through the hinge; the swinging cutter head assembly 320 includes a swinging cutter head 321 and a swinging cutter head driving source 330, the swinging cutter head 321 is hingedly connected to the main sliding knife 311, the swinging cutter head driving source 330 is arranged on the sliding shoe 310, and the swinging cutter head driving source 330 is transmission-connected to the swinging cutter head 321.

[0035] The shallow water planing boat with a swinging blade head of the present invention first fixes the hull 100 on the sea surface through the anchoring mechanism 400, and then the operator lowers the connecting frame 200 into the sea to make the sliding shoe mechanism 300 contact the seabed, and the main sliding blade 311 and the swinging blade head 321 are embedded in the seabed to provide a lateral constraint for the hull 100, so that the load on the hull 100 in the front and rear directions is offset by the anchoring mechanism 400, and the load on the hull 100 in the left and right directions is offset by the main sliding blade 311. 1 and the swinging blade head 321 cooperate to offset, and the loads in the up and down directions on the hull 100 are offset by the connecting frame 200 hinged to the hull 100, and the hinged parts between the connecting frame 200 and the sliding shoe 310; that is, the hull 100 will not drift left and right with the waves when it is fixed on the sea surface for construction. At the same time, the main sliding knife 311 and the swinging blade head 321 are in the form of thin sheets, and the hull 100 is subject to left and right constraints during construction in shallow water areas, thereby ensuring that the hull 100 moves in a straight line and will not collide with obstacles on the sea.

[0036] Preferably, in this embodiment, the hull 100 adopts a barge type to facilitate construction in shallow water areas and provide a larger deck area. The orientation of the main slide 311 and the slide shoe 310 is the same as the bow and stern direction of the hull 100. The connection point between the connecting frame 200 and the hull 100 is a hinge point 210.

[0037] Preferably, Figure 5 , Figure 6As shown, the sliding shoe 310 includes a sliding shoe inclined plate 312 and a sliding shoe bottom plate 317. The sliding shoe inclined plate 312 is arranged at the edge of the sliding shoe bottom plate 317, and the main sliding knife 311 is arranged on the bottom surface of the sliding shoe bottom plate 317; a main sliding knife hinge hole 313 is arranged at the end of the main sliding knife 311, and a swinging knife head hinge hole 322 is arranged at the end of the swinging knife head 321. The main sliding knife hinge hole 313 is aligned with the swinging knife head hinge hole 322, and a vertical hinge shaft 323 passes through the two in the up and down direction; the vertical hinge shaft 323 is fastened to the swinging knife head 321, and the top of the vertical hinge shaft 323 passes through the sliding shoe bottom plate 317 and is transmission-connected to the swinging knife head drive source 330, and the swinging knife head drive source 330 is arranged on the top surface of the sliding shoe bottom plate 317. In this embodiment, the sliding shoe inclined plate 312 is sealed and connected to the sliding shoe bottom plate 317, and the sliding shoe inclined plate 312 is arranged obliquely upward at the edge of the sliding shoe bottom plate 317. The sliding shoe inclined plate 312 and the sliding shoe bottom plate 317 form a ship shape, which ensures that the sliding shoe 310 will not be completely embedded in the mud and sand of the seabed when moving or stationary. The main sliding knife 311 and the swinging knife head 321 are both vertical blade-shaped structures, which are embedded in the seabed mud and sand when working, and are used to provide lateral (left and right) restraint force for the hull 100. The number of the main sliding knife hinge hole 313 and the swinging knife head hinge hole 322 are both two, which are respectively arranged at the opposite end faces of the main sliding knife 311 and the swinging knife head 321 in the up and down directions, and the main sliding knife hinge hole 313 and the swinging knife head hinge hole 322 are arranged crosswise. The spacing between the two swinging knife head hinge holes 322 is smaller than the spacing between the two main sliding knife hinge holes 313. The two swing cutter head hinge holes 322 are tightly connected to the vertical hinge shaft 323 through a key 325. When the vertical hinge shaft 323 rotates, the swing cutter head 321 rotates together. A key slot is provided on the vertical hinge shaft 323, and the key 325 is a flat key.

[0038] Preferably, Figure 3 , Figure 4 As shown, a swing wing plate 324 is further provided between the swing blade driving source 330 and the vertical hinge shaft 323, and the middle part of the swing wing plate 324 is fixedly connected to the vertical hinge shaft 323; the swing blade driving source 330 adopts a spring cylinder, and the number of the swing blade driving sources 330 is two, and swing wing plate connection holes are symmetrically opened on the left and right sides of the connection point between the swing wing plate 324 and the vertical hinge shaft 323, and a small ear plate 316 is provided on the bottom plate 317 of the sliding shoe, and one end of the spring cylinder is connected to the swing wing plate connection hole, and the other end is connected to the small ear plate 316. In this embodiment, when the spring cylinder on the left side contracts, the spring cylinder on the right side extends, and the swing wing plate 324 will deflect to the left, thereby driving the vertical hinge shaft 323 to deflect to the left, and then the swing blade 321 deflects to the left, thereby realizing the steering of the hull 100. Similarly, the working process of the spring cylinder on the right side is similar to that of the spring cylinder on the left side.

[0039] Furthermore, the outer periphery of the horizontal sleeve 314 may be provided with ribs, the ribs extending along the length direction of the sliding shoe 310, the swing wing 324 is provided on the ribs, and the vertical hinge shaft 323 penetrates the ribs from top to bottom.

[0040] Preferably, Figure 7 As shown, the swing cutter head driving source 330 includes a cylinder body 331, a piston rod 332, a piston 333, and a disc spring 334. The piston 333 is arranged at the end of the piston rod 332, and the piston 333 is movably arranged in the cylinder body 331; there are a plurality of disc springs 334, which are arranged in the cylinder body 331. In this embodiment, the total length of the plurality of disc springs 334 is designed so that after the two spring cylinders are installed, the disc springs 334 are just in a slightly compressed state, and the loads on both sides are balanced, which is equivalent to automatically centering the swing cutter head 321 by balancing the two spring cylinders against each other. The disc spring 334 is used because it has a large spring stiffness and can generate a stronger elastic force under a smaller compression amount, which is conducive to having a stronger direction-keeping ability under external interference loads.

[0041] Preferably, Figure 3-Figure 6 As shown, the hinged member includes a horizontal shaft sleeve 314, which is fixed on the top surface of the sliding shoe bottom plate 317. The end of the connecting frame 200 away from the hull 100 is provided with a connecting frame through hole, which is aligned with the horizontal shaft sleeve 314, and a horizontal pin 222 is passed through the two. The end of the connecting frame 200 away from the hull 100 is hingedly connected to the sliding shoe 310 through the connecting frame through hole, the horizontal pin 222, and the horizontal shaft sleeve 314. The sliding shoe 310 can rotate in the vertical direction around the horizontal pin 222, so as to ensure that the sliding shoe 310 is in a horizontal state.

[0042] Preferably, Figure 2-Figure 4 As shown, the connecting frame 200 is a tripod, which includes a main side rod 225 and a secondary side rod 220. One end of the main side rod 225 is hinged on the hull 100, and the other end is provided with a main side rod through hole, and the main side rod through hole is connected to the horizontal shaft sleeve 314 through a horizontal pin 222; one end of the secondary side rod 220 is hinged on the hull 100, and the other end is fixedly connected to the end of the main side rod 225 away from the hull 100. In this embodiment, a U-shaped hinge head 221 is provided at the end of the main side rod 225 away from the hull 100, and the main side rod through hole is provided on the two side walls of the U-shaped hinge head 221, and the two side walls of the U-shaped hinge head 221 are located on the left and right sides of the horizontal shaft sleeve 314.

[0043] Furthermore, in this embodiment, there is a hinge point 210 between the main side rod 225 and the hull 100, and there is a hinge point 210 between the secondary side rod 220 and the hull 100, that is, there are two hinge points 210 between the connecting frame 200 and the hull 100. When the hull 100 heaves or pitches, it can adapt to the movement without causing the sliding shoe mechanism 300 at the end of the connecting frame 200 to rise or fall.

[0044] Preferably, Figure 5 , Figure 6 As shown, the main side rod 225 is also provided with a fixing ear plate 223, and the sliding shoe 310 is also provided with a tail pin hole 315. The fixing ear plate 223 and the tail pin hole 315 are connected by a connecting plate 224. The two ends of the connecting plate 224 are respectively provided with connecting plate through holes. The fixing ear plate 223 is aligned with any connecting plate through hole, and a connecting pin is passed through the two; the tail pin hole 315 is aligned with another connecting plate through hole, and a connecting pin is passed through the two; the connecting plate 224 is replaceable. In this embodiment, the connecting plate 224 is replaceable, that is, the length specification of the connecting plate 224 can be changed. When the length of the connecting plate 224 changes, the angle between the sliding shoe 310 and the main side rod 225 can be different, so that the sliding shoe 310 can be in a horizontal state on the seabed at different depths and different slopes.

[0045] Preferably, Figure 1 , Figure 2 As shown, at least two sets of anchoring mechanisms 400 are provided, which are respectively provided at the head and the tail of the hull 100. The anchoring mechanisms 400 include a winch 401, an anchor cable 402, a fairlead 403, and an anchor claw 404. The winch 401 and the fairlead 403 are both provided on the hull 100. One end of the anchor cable 402 is wound around the winch 401, and the other end of the anchor cable 402 passes through the fairlead 403 and is connected to the anchor claw 404. Further, in this embodiment, the winch 401 is used to retract and release the anchor cable 402, and the fairlead 403 is used to assist in the retracting and releasing of the anchor cable 402. In order to achieve smoother retracting and releasing of the anchor cable 402, a plurality of fixed pulleys may be provided on the hull 100 to support and reverse the anchor cable 402.

[0046] To achieve the above purpose or other purposes, the present invention also discloses a control method for a shallow water planing boat with a swinging cutter head, using the above shallow water planing boat with a swinging cutter head, the steps are as follows:

[0047] A1: First, the operator manufactures the above components according to the above description and assembles the components and connects them to the hull 100;

[0048] A2: Then, the operator controls the hull 100 to move toward the shallow water construction area. When it reaches the construction location next to the offshore obstacle (such as Figure 2As shown in FIG. 1 , the anchor claw 404 and the anchor cable 402 on the anchoring mechanism 400 are led out to a certain distance in the front and rear direction of the hull 100 by the anchoring ship, and the anchor cable 402 is tightened by the winch 401 in the anchoring mechanism 400, and the anchor claw 404 is deeply inserted into the seabed, so that the hull 100 is fixed in the front and rear direction by the anchor claw 404;

[0049] A3: The operator selects connecting plates 224 of different lengths and specifications according to the depth of the seabed in the construction area to connect the fixed ear plate 223 on the main side rod 225 with the tail pin hole 315 on the sliding shoe 310, and then rotates the connecting frame 200 so that the sliding shoe mechanism 300 at the end of the connecting frame 200 abuts against the seabed, and the main sliding knife 311 and the swinging knife head 321 penetrate into the seabed mud in the front and rear directions, thereby offsetting the load on the hull 100 in the left and right directions; the through hole of the connecting frame is hinged on the horizontal shaft sleeve 314 through the horizontal pin shaft 222, so that when the hull 100 is subjected to the load in the up and down directions, the connecting frame 200 will swing in the up and down directions around the horizontal pin shaft 222, thereby offsetting the load in the up and down directions, so that the hull 100 can float stably on the sea surface (such as Figure 1 , Figure 2 shown);

[0050] A4: When the hull 100 in step A3 is floating stably on the sea surface, the construction equipment on the hull 100 performs construction operations; when the construction of the hull 100 is completed at this location and needs to move forward to the next location, the operator tightens the front anchor cable 402 through the winch 401 and loosens the rear anchor cable 402 at the same time, and the main slide 311 guides on the seabed, so that the hull 100 will move toward the front end, and vice versa.

[0051] When the hull 100 deviates and needs to adjust its direction, the operator controls the spring cylinder on one side to extend and the spring cylinder on the other side to be compressed. The extension of the spring cylinder pushes the swing wing plate 324 to deflect, and then the vertical hinge shaft 323 follows the deflection of the swing wing plate 324. The vertical hinge shaft 323 drives the swinging cutter head 321 to rotate through the key 325, and then the hull 100 is moved in the set direction by retracting and releasing the anchor cable 402; the deflection angle of the swinging cutter head 321 is adjusted by the extended length of the spring cylinder. Generally speaking, the swinging cutter head 321 only needs to be deflected by a very small angle, and the hull 100 can complete the deviation correction after running a certain distance.

[0052] After the angle of the hull 100 is adjusted, the swinging blade head 321 still needs to return to the center position. The swinging wing plate 324 is placed in the center position by controlling the spring cylinders on both sides, thereby ensuring that the swinging blade head 321 is in the center position.

[0053] The shallow water planing boat with a swinging cutter head according to the present invention has the following beneficial effects:

[0054] 1. In the present invention, the combined action of the anchoring mechanism 400 and the sliding shoe mechanism 300 enables the hull 100 to move in a straight line in shallow water without drifting left and right.

[0055] 2. A tail pin hole 315 is provided on the sliding shoe 310, and a fixing ear plate 223 is provided on the main side rod 225. The tail pin hole 315 and the fixing ear plate 223 are connected by connecting plates 224 of different lengths. In this way, connecting plates 224 of different specifications can be replaced according to the water depth to ensure that the sliding shoe bottom plate 317 is basically in a horizontal state and will not be embedded in the seabed mud.

[0056] 3. A swinging cutter head 321 is provided at the bottom of the sliding shoe 310, and a swinging cutter head driving source 330 is provided at the top of the sliding shoe 310. The swinging cutter head 321 is driven by the swinging cutter head driving source 330 to deflect a certain angle, so as to adjust the steering of the hull 100, thereby correcting the lateral deviation of the hull 100.

[0057] 4. The mooring mechanism 400 can anchor for hundreds of meters, the hull 100 is about tens of meters long, the hull 100 can move more than ten positions before adjusting the anchor position, and the hull 100 can work along the construction area, and the operation effect is significantly improved.

[0058] 5. The connecting frame 200 and the sliding shoe mechanism 300 of the present invention have low manufacturing costs, and the mooring mechanism 400 can adopt the equipment on the original hull 100, which has low cost and is easy to promote, thus solving the problem that some construction areas cannot anchor normally and the risk of moving the ship is high.

[0059] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
