[0024] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.
[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
[0026] like Figure 1 , Figure 2 As shown, the present invention is a wave-breaking board for a three-purpose work boat, including a wave-breaking board body 11, which can be slidably arranged in a wave-breaking groove 9 on the hull, and a lifting device for lifting the wave-breaking board body 11 is provided in the wave-breaking groove 9. When the lifting device falls, the top surface of the wave-breaking board body 11 is flush with the top surface of the hull deck 2. The wave-breaking board body 11 is made of cast iron to ensure the strength of the wave-breaking board. When the lifting device is lifted, the upper part 6 of the wave-breaking board body 11 is exposed to block the impact of waves. When the lifting device falls, the wave-breaking board is located in the wave-breaking groove 9 as a whole, and the hull deck operation can be carried out to avoid obstruction to the deck work when it is not needed.
[0027] In this embodiment, the wave-breaking board body 11 is provided with a plurality of water holes 5 and 10 penetrating from front to back.
[0028] In this embodiment, the main body 11 of the wave-breaking board includes an upper part 6 exposed from the wave-breaking groove 9 when jacking up, and a lower part 3 always located in the wave-breaking groove 9, and the water holes 5, 10 are located in the upper part 6 of the main body of the wave-breaking board. The upper part 6 exposed from the wave-breaking groove 9 when jacking up is 0.9 meters higher than the deck; the width of the main body 11 of the wave-breaking board is 60% of the width of the deck, so as to ensure that the impact of the waves is alleviated to the minimum extent.
[0029] In this embodiment, the lower half 3 of the wave-breaking board body is a box-type structure, and the box-type structure is closely matched with the wave-breaking groove 9, and the wave-breaking groove 9 provides support for the box-type structure.
[0030] In this embodiment, the water holes include a columnar water hole 10 located at the top and a three-dimensional branched water hole 5 located at the bottom. The three-dimensional branched water hole 5 is composed of a main channel in the front half and several branched channels in the back half that are interconnected, and the several branched channels are inclined in several different directions. The three-dimensional branched water holes 5 are divided into two types, the bottom holes are large in size and sparsely distributed, and the upper holes are small in size and densely distributed; the columnar water holes 10 are of uniform size and evenly distributed.
[0031] In this embodiment, the lifting device is a hydraulic jack 8, and a channel 1 is provided on the hull for the hydraulic jack 8 to move up and down. The bottom of the hydraulic jack 8 is connected to a hydraulic device, and the hydraulic device is installed in the hull.
[0032] In this embodiment, a support block 7 is welded to the bottom of the wave-breaking board body 11. The purpose of providing the support block 7 is to increase the force-bearing area of the lower surface of the box-shaped structure and the top of the hydraulic push rod 8, thereby improving the service life of the present invention. When the hydraulic push rod 8 is lifted, the top of the hydraulic push rod 8 contacts the support block 7; when the hydraulic push rod 8 falls, the top of the hydraulic push rod 8 is separated from the support block 7 (see Figure 3 , Figure 4 ), at this time, the wave-breaking groove 9 supports the wave-breaking board body 11 to avoid damage to the hydraulic device due to problems with loading and unloading cargo on the deck when the wave-breaking board is not in use.
[0033] In this embodiment, there are two hydraulic push rods 8 and two channels 1, which are respectively located at 1 / 4 and 3 / 4 of the total length of the bottom of the wave-blocking groove 9.
[0034] In this embodiment, the four bottom corners of the wave-breaking board body 11 are all configured as rounded corners 4, so as to avoid the problem of the wave-breaking board body 11 being stuck due to horizontal force during the descending process.
[0035] When the wavebreak of the present invention is in use, the lifting device is raised, and the upper half 6 of the wavebreak body is exposed. When the deck 2 is hit by waves, the waves are broken and separated through the water holes 5 and 10, and the impact force of the waves is greatly weakened after passing through the wavebreak; at the same time, the lower half 3 of the wavebreak body is always located in the wavebreak groove 9, providing a torque to cope with the impact force of the waves. When the wavebreak is not in use, the wavebreak body 11 and the lifting device are separated, and the wavebreak as a whole is located in the wavebreak groove 9, and the wavebreak groove 9 supports the wavebreak body, and the deck strength is borne by the wavebreak body itself, which meets the requirements for deck strength.
[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
