Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shipbuilding, in particular to an underwater anti-destruction paint device for ships. Background Art
[0002] The underwater anti-destruction paint device for ships is a device used to protect ships from damage by lashing wires during the launching process. Its main functions should be: protection, which can prevent the paint surface from being damaged by the lashing wires during the launching process; safety guarantee, which ensures the safety of the ship launching process and avoids safety accidents caused by the breakage or damage of the lashing wires; extending the service life, which ensures the protection of the ship from damage by the lashing wire ropes, extends the service life of the ship, and reduces the cost of maintenance or replacement; improving efficiency, which reduces delays in ship launching caused by problems with the lashing wire ropes and improves work efficiency; reducing costs, which can reduce the total cost of ship launching through preventive maintenance and timely repairs.
[0003] The existing underwater anti-destruction paint device for ships is to install a nylon ball on the wire rope so that the wire rope does not directly contact the ship's painted surface to avoid paint damage. However, the existing device has certain disadvantages: first, the spherical device has a small contact area with the outer plate, resulting in a relatively large pressure after being stressed. When the wire rope and the round ball hit the paint surface together, the increased pressure on the round ball causes the spherical device to hit the paint surface with too much force, causing damage to the paint surface and prolonging the ship's launching time; second, the spherical device cannot be set with a device that can restrain the wire rope. Therefore, the wire rope shakes and swings in the spherical device, which makes it impossible for the spherical device to actively limit the movement of the wire rope, causing the wire rope to drive the spherical device to hit the paint surface more times, thereby increasing the probability of the paint surface being damaged, while reducing the possibility of the wire rope breaking or being damaged due to its autonomous swing; thirdly, the spherical device has no buffering and shock-absorbing measures. When the spherical device hits the paint surface with the swinging movement of the wire rope, the wire rope and the device can directly hit the paint surface because there are no buffering and shock-absorbing measures, causing damage to the paint surface. Utility Model Content
[0004] (1) Technical problems solved
[0005] In response to the deficiencies in the prior art, the utility model provides an underwater anti-destruction paint device for ships, which has the advantages of increasing the force-bearing area between the device and the ship, reducing the force pressure, thereby reducing the impact force of the spherical device when the wire rope swings, limiting the movement of the wire rope, reducing the number of collisions, reducing the probability of the wire rope being worn and broken due to excessive movement, and having sufficient buffering measures and excellent shock-absorbing ability, so that the paint surface is subjected to less impact force and can better protect the paint surface. It solves the problems of the device having a small force-bearing area so that the force of hitting the paint surface is too large, causing damage to the paint surface, the wire rope being unconstrained, causing the wire rope to swing freely, thereby driving the device to hit the paint surface multiple times, the free swinging causing long-term wear of the parts, resulting in damage and breakage, and the device having no buffering ability, which easily causes the wire rope belt device to directly contact the paint surface and cause damage to the paint surface.

[0017] (3) Beneficial effects
[0018] Compared with the prior art, the present invention provides an underwater anti-destruction paint device for ships, which has the following beneficial effects:
[0019] 1. The underwater anti-destruction paint device for ships is provided with an external protection module. By assembling a first external protection shell and a second external protection shell, a cylindrical underwater anti-destruction paint device for ships is formed. The cylindrical protection device makes the contact area between the device and the paint on the ship larger, which also makes the force-bearing area of the device larger, reducing the force pressure and thus the impact force of the steel wire rope driving the device hitting the paint surface when it moves, thereby ensuring the time of launching the ship to a certain extent.
[0020] 2. The underwater anti-destruction paint device for ships is provided with an internal protection module, a first fastener, a second fastener and a steel wire rope soft protection module. Through the assembly between these devices, the device can firmly bind the steel wire rope, thereby limiting the free swinging of the steel wire rope in the protection device, thereby reducing the number of times the device hits the paint surface due to the swing of the steel wire rope, and protecting the ship's paint surface to a certain extent. At the same time, because the movement of the steel wire rope is greatly restricted, the steel wire rope will not swing frequently, and the steel wire rope will not break due to friction between the steel wire rope and the ship's hull due to the swing. This protects the ship body and the paint surface to a certain extent, and extends the service life of the ship and the paint surface.
[0021] 3. The underwater anti-destruction paint device of the ship is provided with an external protection module and an external soft protection module. Through the use of an external anti-collision airbag, when the device is swung by the wire rope, the external anti-collision airbag can provide the first layer of shock absorption and buffering. When the swing impact amplitude is too large and the first layer of shock absorption and buffering fails, the use of the first rubber soft shell and the second rubber soft shell makes it possible to absorb the remaining impact force after the first layer of shock absorption and buffering by the second layer of shock absorption and buffering composed of the first rubber soft shell and the second rubber soft shell. This, to a certain extent, avoids the wire rope carrying the device directly hitting the ship body and paint surface to cause damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0031] See also Figure 1-4 The illustrated device is an underwater anti-destruction paint device for a ship, comprising an internal protection module 1, wherein the top and bottom of the internal protection module 1 are fixedly connected to a first support frame 2, the internal protection module 1 is fixedly connected to a first fastener 3 through the first support frame 2, the surface of the first fastener 3 is fixedly connected to a first threaded hole base 4, the inner wall of the first threaded hole base 4 is threadedly connected to a first bolt, the first threaded hole base 4 is threadedly connected to a second fastener 5 through the first bolt, the bottom of the second fastener 5 is fixedly connected to a second support frame 6, the second fastener 5 is fixedly connected to the internal protection module 1 through the second support frame 6, a hole is opened on the surface of the internal protection module 1, a steel wire rope soft protection module 7 is provided on the inner wall of the hole, an external protection module 8 is provided on the surface of the internal protection module 1, and an external soft protection module 9 is provided on the surface of the external protection module 8, a steel wire rope 10 is provided on the inner wall of the internal protection module 1, the first fastener 3, and the second fastener 5, and the steel wire rope 10 and the internal protection module 1, the first fastener 3, and the second fastener 5 are adapted to each other.
[0032] The first support frame 2 is welded between the internal protection module 1 and the first fastener 3, and the second support frame 6 is welded between the internal protection module 1 and the second fastener 5. The first threaded hole base 4 is welded on both sides of the first fastener 3. The first bolt is screwed into the first threaded hole base and continues to rotate until it is screwed into the second fastener 5 to complete the assembly between the first fastener 3 and the second fastener 5. The wire rope soft protection module 7 is installed in the hole on the surface of the internal protection module 1, the external protection module 8 is installed on the outside of the internal protection module 1, and the external soft protection module 9 is installed on the surface of the external protection module 8.
[0033] When using the device, the internal protection module 1, the first fastener 3, the second fastener 5 and the wire rope soft protection module 7 are used to wrap and fix the wire rope 10, and then the external protection module 8 is installed on the surface of the internal protection module 1 to form an external protection, and then the external soft protection module 9 is installed on the surface of the external protection module 8 to form the outermost soft protection device. When the wire rope swings, it drives the external soft protection module 9 to hit the hull first. When the external soft protection module 9 fails, the external protection module 8 also hits the hull and absorbs the impact kinetic energy to the greatest extent to protect the paint surface.
[0034] By providing an internal protection module 1, a first fastener 3, a second fastener 5 and a wire rope soft protection module 7, and by assembling these devices, the device can firmly bind the steel wire 10, thereby limiting the free swing of the steel wire rope 10 in the protection device, thereby reducing the number of times the device hits the paint surface due to the swing of the steel wire rope 10, protecting the ship's paint surface to a certain extent. At the same time, because the movement of the steel wire rope 10 is greatly restricted, the steel wire rope 10 will not swing frequently, which will prevent the steel wire rope 10 from breaking due to friction between the steel wire rope 10 and the ship's hull due to the swing. This protects the ship's body and paint surface to a certain extent, and extends the service life of the ship and the paint surface.
[0035] The internal protection module 1 includes a first internal protection shell 101, a mortise groove is provided on the side of the first internal protection shell 101, a mortise 102 is inserted into the inner wall of the mortise groove, and a second internal protection shell 103 is fixedly connected to one side of the mortise 102. A first threaded hole is provided on the surface of the first internal protection shell 101, a second bolt is threadedly connected to the inner wall of the first threaded hole, and the first threaded hole is threadedly connected to the mortise 102 through the second bolt.
[0036] The tenon 102 is integrally formed with the second internal protective shell 103, and the tenon groove is integrally formed with the first internal protective shell 101. The tenon 102 is inserted into the tenon groove on the first internal protective shell 101, thereby driving the second internal protective shell 103 and the first internal protective shell 101 to be assembled, and then the second bolt is screwed into the first threaded hole on the first internal protective shell 101 to complete the assembly. When in use, the first internal protective shell 101 and the second internal protective shell 103 are respectively placed on both sides of the wire rope 10, and then the tenon 102 is inserted into the tenon groove to connect the first internal protective shell 101 and the second internal protective shell 103, and the second bolt is screwed into the first threaded hole to complete the process operation.
[0037] like Figure 5 As shown, the wire rope soft protection module 7 includes a straight rod 701, a spring 702 is installed on the surface of the straight rod 701, a knob head 703 is threadedly connected to the top of the straight rod 701, one end of the straight rod 701 is fixedly connected to a rubber pad base 704, and a rubber pad 705 is provided on the inner wall of the rubber pad base 704, and the spring 702 and the hole are adapted to each other.
[0038] The straight rod 701 and the rubber pad base 704 are connected as one. Pass the straight rod 701 through the hole, then install the spring 702 on the straight rod 701, and then screw the knob head 703 onto the straight rod 701. Finally, glue the rubber pad 705 to the inner wall of the rubber pad base 704 by bonding to complete the installation. When in use, assemble the device according to the above steps, and then hold the knob head 703 in your hand to push the straight rod 701 forward, so that the straight rod 701 drives the rubber pad base 704 to move forward until the rubber pad 705 contacts the surface of the wire rope and presses against the wire rope, completing the process operation.
[0039] like Figure 6-Figure 7 As shown, the external protection module 8 includes a first external protection shell 801, and the surface of the first external protection shell 801 is fixedly connected with a first rubber soft shell 802 and a second threaded hole base 803 from top to bottom, the inner wall of the second threaded hole base 803 is threadedly connected with a third bolt, and the second threaded hole base 803 is threadedly connected with a second external protection shell 804 through the third bolt, and the surface of the second external protection shell 804 is fixedly connected with a second rubber soft shell 805.
[0040] The first rubber soft shell 802 and the second threaded hole base 803 are both integrally formed with the first external protective shell 801. The second external protective shell 804 is placed on the first external protective shell 801 and aligned with the second threaded hole base 803 on the first external protective shell 801. Then, the third bolt is screwed into the second threaded hole base 803 and continues to rotate until it is screwed into the second external protective shell 804. The second rubber soft shell 805 is integrally formed with the second external protective shell 804 to complete the assembly. When in use, the first external protective shell 801 and the second external protective shell 804 are respectively placed on both sides of the internal protective module 1, and then the first external protective shell 801 and the second external protective shell 804 are aligned. Then, the first external protective shell 801 and the second external protective shell 804 are connected and assembled by using the third bolt, so that the first external protective shell 801 and the second external protective shell 804 tightly wrap the internal protective module 1 to complete the process operation.
[0041] like Figure 7 As shown, the external soft protection module 9 includes an arc-shaped plate 901, the surface of the arc-shaped plate 901 is fixedly connected with a plate groove, the top of the plate groove is provided with a second threaded hole, the inner wall of the second threaded hole is threadedly connected with a fourth bolt, the second threaded hole is threadedly connected with a connecting plate 902 through the fourth bolt, and one side of the connecting plate 902 is fixedly connected with an external anti-collision airbag 903, and the plate groove and the connecting plate 902 are adapted to each other.
[0042] The plate groove is integrally formed with the curved plate 901. Place the connecting plate 902 into the plate groove, and then screw the fourth bolt into the second threaded hole on the plate groove. The connecting plate 902 is integrally formed with the external anti-collision airbag 903, so that the installation is completed. When in use, assemble the module according to the above steps, and then clip the curved plate 901 into the surface of the external protection module 8, so that the module is installed on the external protection module 8 to form a first layer of shock absorption and buffering. When the movement of the wire rope drives the entire device to impact the hull, the first layer of shock absorption and buffering is performed through the external anti-collision airbag 903 of the external soft protection module 9, so that the impact force of the device hitting the paint surface is greatly reduced, and the impact kinetic energy is greatly absorbed to complete the operation process.
[0043] By providing an external protection module 8 and assembling the first external protection shell 801 and the second external protection shell 804, a cylindrical ship underwater anti-destruction paint device is formed. The cylindrical protection device formed makes the contact area between the device and the paint on the ship larger, which also makes the force-bearing area of the device larger, reducing the force pressure and thus making the impact force of the steel wire rope 10 hitting the paint surface when the device moves, thereby ensuring the time for the ship to be launched into the water to a certain extent.
[0044] By providing an external protection module 8 and an external soft protection module 9, and by using an external anti-collision airbag 903, when the device is swung by the steel wire rope 10, the external anti-collision airbag 903 can perform a first layer of shock absorption and buffering. When the swing impact amplitude is too large and the first layer of shock absorption and buffering fails, the first rubber soft shell 802 and the second rubber soft shell 805 are used, so that after the first layer of shock absorption and buffering, the remaining impact force can be absorbed by the second layer of shock absorption and buffering composed of the first rubber soft shell 802 and the second rubber soft shell 805. This to a certain extent avoids the steel wire rope 10 carrying the device directly hitting the ship body and paint surface to cause damage.

The outer protective module 8 is installed on the outside of the inner protective module 1, and the outer soft protective module 9 is installed on the surface of the outer protective module 8. The tenon 102 is integrally formed with the second inner protective shell 103, and the tenon groove is integrally formed with the first inner protective shell 101. The tenon 102 is inserted into the tenon groove on the first inner protective shell 101, thereby driving the second inner protective shell 103 and the first inner protective shell 101 to be assembled, and then the second bolt is screwed into the first inner protective shell 101. The assembly is completed in a threaded hole. The straight rod 701 and the rubber pad base 704 are connected as a whole. The straight rod 701 is passed through the hole, and then the spring 702 is installed on the straight rod 701. Then the knob head 703 is screwed onto the straight rod 701. Finally, the rubber pad 705 is bonded to the inner wall of the rubber pad base 704 by bonding. The installation is completed. The first rubber soft shell 802 and the second threaded hole base 803 are integrally formed with the first external protective shell 801. The second external protective shell 804 is placed on the first external protective shell 801 and connected with the second external protective shell 804. Align the second threaded hole base 803 on an external protective shell 801, then screw the third bolt into the second threaded hole base 803 and continue to rotate until it is screwed into the second external protective shell 804.
