Description

Technical Field

[0001] The invention relates to the technical field of ship cables, and in particular to a cable tensioning early warning device for ship mooring. Background Art

[0002] As one of the essential tools for mooring a ship, the function of the cable is to connect one end to the ship and the other end to a fixed object on the shore, thereby restraining the ship and preventing it from drifting away from the shore.

[0003] Nowadays, cables need to withstand huge tension during use, especially when the wind and waves are strong, the cables will withstand greater tension. As the service life increases, the strength and tensile resistance of the cables will gradually decrease. Therefore, cables often break due to overload, causing unnecessary economic losses. In order to prevent the cables from breaking due to excessive force, it is best to monitor the force of the cables in real time and issue an alarm when the tension approaches the critical value.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 and Figure 2The embodiment of the present application proposes a cable tensioning warning device for ship mooring, including a cable tensioning mechanism 100, a distance measuring sensor 200, a signal transmitter 300 and a receiving warning terminal (not shown in the figure), wherein the cable tensioning mechanism 100 includes a first shell 101 and a second shell 102, the first shell 101 and the second shell 102 are both box structures with one end open, the open ends of the first shell 101 and the second shell 102 are arranged opposite to each other, and the first shell 101 is sleeved on the outside of the second shell 102, and the bottom surfaces of the first shell 101 and the second shell 102 are both provided with rollers 103; the inner surface of the first shell 101 and the outer surface of the second shell 102 are in contact with each other, and the two are slidably connected.

[0033] More specifically, the first shell 101 is provided with a plurality of first guide columns 104 distributed along its length direction, and a first positioning plate 105 is commonly provided at the ends of the plurality of first guide columns 104, and a plurality of second guide columns 106 are provided inside the second shell 102, the second guide columns 106 are parallel to the first guide columns 104, and the ends of the plurality of second guide columns 106 all penetrate the first positioning plate 105 and are commonly provided with a second positioning plate 107, and the outer sides of the first guide columns 104 and the second guide columns 106 are both sleeved with tensioning springs 108, the tensioning springs 108 are located between the first positioning plate 105 and the second positioning plate 107, and the two ends of the tensioning springs 108 are respectively abutted against the first positioning plate 105 and the second positioning plate 107; the first guide columns 104 and the second guide columns 106 are both distributed along the length direction of the first shell 101, and the first guide columns 104 and the second guide columns 106 are respectively fixedly connected to the inner walls of the first shell 101 and the second shell 102.

[0034] In addition, a first limiting rod 109 is provided on the inner wall of the first shell 101, and a second limiting rod 110 is provided on the inner wall of the second shell 102. Both the first limiting rod 109 and the second limiting rod 110 are parallel to the first guide column 104, and the first limiting rod 109 penetrates the second positioning plate 107 and the first positioning plate 105 respectively, and is also fixedly connected to the first positioning plate 105. The second limiting rod 110 penetrates the first positioning plate 105 and the second positioning plate 107 respectively, and is also fixedly connected to the second positioning plate 107. A limiting sleeve 113 is also provided at the middle position of the first limiting rod 109 and the second limiting rod 110; in the initial state, the tension spring 108 is in a slightly compressed state. When the first shell 101 and the second shell 102 are pulled away from each other by a force, the distance between the first positioning plate 105 and the second positioning plate 107 is gradually reduced, so that the tension spring 108 is continuously compressed.

[0035] It is worth mentioning that a first fixing column 111 is provided at the outer end of the first shell 101, and a second fixing column 112 is provided at the outer end of the second shell 102. The first fixing column 111 is used to connect with a fixed object on the hull, and the second fixing column 112 is used to connect a cable, and the cable is used to connect with a fixed object on the shore, so as to limit the position of the ship.

[0036] Furthermore, the distance sensor 200 is arranged in the first shell 101, and the detection end of the distance sensor 200 points to the second positioning plate 107; the signal transmitter 300 is arranged in the first shell 101, and the distance sensor 200 is connected to the receiving warning terminal through the signal transmitter 300. The distance sensor 200 is used to measure the distance from the second positioning plate 107 to the inner wall of the first shell 101 in real time, and transmit the signal to the receiving warning terminal, which includes a signal receiving module, a signal processing module, a display screen and an alarm module, wherein the signal processing module is used to convert the distance signal into a tension signal, and transmit the tension signal to the display screen for display. When the tension is too large, the alarm module is activated to sound an alarm to remind the staff that the force on the cable is too large.

[0037] To sum up, in the specific implementation of this embodiment, the cable tensioning mechanism 100 is connected to the cable. When the force on the cable increases, the first shell 101 and the second shell 102 will produce relative displacement, thereby compressing the tensioning spring 108. Therefore, the sum of the elastic forces of several tensioning springs 108 is equivalent to the force on the cable. The receiving early warning terminal can convert the compression amount of the tensioning spring 108 into the tension of the cable.

[0038] Specifically in this embodiment, since a limiting sleeve 113 is also provided in the middle position of the first limiting rod 109 and the second limiting rod 110, when the compression amount of the tension spring 108 is too large, the first positioning plate 105 and the second positioning plate 107 will abut against the limiting sleeve 113, thereby protecting the tension spring 108 and preventing the tension spring 108 from being overly compressed and causing irreversible damage. It should be noted that, specifically in this embodiment, when the second positioning plate 107 moves to the position of the limiting sleeve 113, the total elastic force of the plurality of tension springs 108 is 80 tons.

[0039] Example 2: Please refer to Figure 3 - Figure 8The embodiment of the present application proposes a cable tensioning warning device for mooring and docking. The difference between this embodiment and the first embodiment is that a seat plate 500 is provided below the cable tensioning mechanism 100, a rotating seat 400 is rotatably provided on the top surface of the seat plate 500, the first shell 101 is fixedly connected to the rotating seat 400, and the seat plate 500 is fixedly installed on the hull. Since the ship is easily affected by wind and waves on the water, the ship will inevitably shift to a certain extent. At this time, the cable will pull the cable tensioning mechanism 100 to swing, that is, pull the rotating seat 400 to rotate on the seat plate 500.

[0040] Furthermore, the first positioning plate 105 is provided with a plurality of first through holes 114 facing the first guide column 104, the first positioning plate 105 is also provided with a plurality of second through holes 118 for the second guide column 106 to pass through, and the four corners of the first positioning plate 105 are provided with limiting holes for the first limiting rod 109 and the second limiting rod 110 to pass through. A displacement plate 115 is movably provided on the side of the first positioning plate 105 facing away from the second positioning plate 107, and a third through hole 116 is movably provided on the displacement plate 115 for the second guide column 106 to pass through. An embedded rod 117 is provided on the displacement plate 115 and at a position facing the first through hole 114. The first guide column 104 is a hollow tube structure, and the embedded rod 117 is movably inserted into the corresponding first guide column 104. Specifically, the embedded rod 117 and the first guide column 104 are slidably matched.

[0041] On the other hand, the diameter of the first through hole 114 is not less than the diameter of the tension spring 108, and one end of the tension spring 108 extends into the inner side of the first through hole 114. The outer sleeve of the embedded rod 117 is provided with an abutment ring 119, and the abutment ring 119 is fixedly connected to the displacement plate 115; when the displacement plate 115 is fitted with the first positioning plate 105, the abutment ring 119 is embedded in the first through hole 114, and the corresponding tension spring 108 abuts against the abutment ring 119. It should be noted that in the first embodiment, one end of the tension spring 108 directly abuts against the first positioning plate 105, while in the present embodiment, the tension spring 108 abuts against the abutment ring 119, which is the fundamental difference between the present embodiment and the first embodiment.

[0042] In order to enable the displacement plate 115 to slide along the length direction of the first guide column 104, in the present embodiment, a plurality of mounting columns 120 are provided on the side of the first positioning plate 105 facing away from the second positioning plate 107, and the ends of the plurality of mounting columns 120 are commonly connected to an assembly plate 121, and a plurality of fourth through holes 122 are penetrated through the assembly plate 121 for the second guide column 106 to pass through, and the displacement plate 115 is located between the assembly plate 121 and the first positioning plate 105, and a screw 123 is provided on the assembly plate 121 that rotates toward the side of the displacement plate 115, and a screw sleeve 124 is fixedly provided on the side of the displacement plate 115 that faces the assembly plate 121, and the screw 123 is threadedly connected to the screw sleeve 124; therefore, the axial directions of the screw 123 and the screw sleeve 124 are consistent with the axial direction of the first guide column 104, and when the screw 123 rotates, the displacement plate 115 can be driven to approach or move away from the assembly plate 121.

[0043] In this embodiment, the top surface of the seat plate 500 is provided with a slide rail 501 along its radial direction, and a displacement block 502 is slidably provided on the slide rail 501. A winding wheel 127 is sleeved on the outside of the screw rod 123, and a rope 128 is wound around the outside of the winding wheel 127. The end of the rope 128 passes through the second housing 102 and is fixedly connected to the displacement block 502. A threading tube 125 is provided on the bottom surface of the second housing 102, and two limiting arc plates 503 are provided on the top surface of the displacement block 502. The bottom end of the threading tube 125 extends between the two limiting arc plates 503, and the end of the rope 128 passes through the threading tube 125 and is connected to the displacement block 502. In the initial state, the centers of the circles corresponding to the two limiting arc plates 503 coincide with the central axis of the rotating seat 400, and the spacing between the limiting arc plates 503 is slightly larger than the diameter of the threading tube 125, and the bottom end of the threading tube 125 can move freely between the two limiting arc plates 503.

[0044] It should be noted that a spring 126 is sleeved on the outer side of the screw 123, the inner end of the spring 126 is fixedly connected to the screw 123, and the outer end of the spring 126 is fixedly connected to the assembly plate 121; in a natural state, the spring 126 is in a tightened state, and the rope 128 is in a straightened state. When the rope 128 is pulled by an external force, the winding wheel 127 will rotate, and the spring 126 will be further tightened; when the rope 128 is released by an external force, the screw 123 can be driven to rotate under the torsion of the spring 126, so that the rope 128 is always in a tightened state.

[0045] It is worth mentioning that, in the initial state of this embodiment, the length direction of the first shell 101 and the second shell 102 must be kept consistent with the length direction of the cable and the length direction of the slide rail 501, and at this time, the bottom end of the threading tube 125 is located in the middle position of the two limiting arc plates 503, the displacement plate 115 is in contact with the first positioning plate 105, and the abutment ring 119 is located on the inner side of the first through hole 114.

[0046] When the ship is affected by wind and waves and pulls the cable, the first shell 101 and the second shell 102 slide relative to each other, the tension spring 108 is compressed, and the signal transmitter 300 transmits the compression signal to the receiving warning terminal in real time. Due to the uncontrollability of the direction of wind and waves, there must be a certain angle between the direction of the ship's force and the direction of the cable. The external force can be decomposed into a force parallel to the direction of the cable, hereinafter referred to as F1, and a force perpendicular to the direction of the cable, hereinafter referred to as F2. Among them, the tension F1 offsets the tension of the cable, and the tension F2 will push the ship to swing around the cable fixed point, so that the rotating seat 400 will rotate.

[0047] As is known to all, when the tension F1 is larger, it can be offset by the cable. When the tension F2 is larger, the ship will swing with the cable as the radius. At this time, the ship is very likely to hit other obstacles and cause unnecessary damage. Therefore, the farther the ship deviates from the initial position, the higher the risk factor of the ship. At this time, we hope that the cable tension warning device has a higher sensitivity. Based on this, the seat plate 500 and the rotating seat 400 structure are set in this embodiment.

[0048] When the ship swings toward the cable side, the rotating seat 400 will rotate, so that the bottom end of the threading tube 125 moves between the two limit arc plates 503, and then the rope 128 pulls the winding wheel 127 and the screw 123 to rotate, and finally the displacement plate 115 moves toward the assembly plate 121, and the tension spring 108 will stretch, and the elastic force of the tension spring 108 will decrease. Therefore, when the ship deviates from the initial position, the displacement distance of the displacement plate 115 is greater, and the pulling force of the second positioning plate 107 to the alarm distance is smaller, that is, the higher the sensitivity, the easier it is to trigger the alarm.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
