The present invention will be described in detail with reference to the accompanying drawings.
As shown in figure 1, the utility model provides an anti impact structure suitable for icebreaker topside, including upper portion sandwich panel 2-1, lower part sandwich panel 2-2 and anti impact structure. The upper sandwich plate 2-1 and the lower sandwich plate 2-2 are arranged in parallel, and the shock-resistant structure is positioned between the upper sandwich plate 2-1 and the lower sandwich plate 2-2.
As shown in fig. 2, the upper sandwich panel 2-1 and the lower sandwich panel 2-2 are each composed of a set of skin panels 3-2 and sandwich panels 3-1. The surface of the skin plate is coated with an insulating layer. The sandwich plates 3-1 are positioned between the skin plates which are arranged in parallel and are arranged in a wave shape. The gap between the skin plate 3-2 and the sandwich plate 3-1 is provided with a first filler.
The insulating material is water-based fluorocarbon coating, the coating has excellent high temperature resistance, weather resistance, corrosion resistance, pollution resistance and cold resistance, and can not cause poisoning phenomenon if food is carelessly contacted with the coating, so that the insulating material is a very safe and reliable product, and the protective effect of the coating reaches 20 a. The coating is of a baking type and a self-drying type, so that the coating is very convenient to construct and coat, the whole construction process is rapid and timely, and the use of the ship body is not influenced.
The first filler is TPEE/PVC elastomer alloy material, has plasticity and elasticity, high mechanical strength and good cold resistance, can replace rubber, plastic and metal, and is called engineering elastomer.
The skin plate 3-2 and the sandwich plate 3-1 are both made of 52CnMnB high-strength spring steel, and have excellent fatigue resistance, elastic reduction resistance, heat resistance, low temperature resistance, oxidation resistance and corrosion resistance. It also has high tensile strength, yield ratio, plasticity, toughness, etc.
As shown in figure 3, the anti-impact structure is symmetrical about the left and the right, and is provided with a tooth-like pressure-resistant device 2-5, a backing plate 2-4, an elliptical pressure-resistant device 2-8, a spring 2-7 and a second filler 2-6 respectively at the left and the right of a group of arched plates 2-3. The group of arch plates 2-3 are welded between the upper sandwich plate 2-1 and the lower sandwich plate 2-2, the group of backing plates 2-4 are used for supporting the tooth-like compression-resistant device 2-5, the oval compression-resistant device 2-8 is embedded in the tooth-like compression-resistant device 2-5, and the second filler is located in a gap between the tooth-like compression-resistant device 2-5 and the oval compression-resistant device 2-8. The structural strength and the compression resistance are effectively guaranteed. The arched plates on the two sides bear the impact force of most ice surfaces on the side of the icebreaking ship, and the icebreaking ship has the advantages of stability and compression resistance. The redundant impact force can be dispersed on the tooth-like compression-resistant device, and the teeth on the device can effectively disperse the force and reduce the impact of stress. When the tooth-like tooth pressure-resistant device is stressed to bend inwards and the internal oval pressure-resistant device is stressed to bend outwards, the rest force is reduced by buffering and offsetting the second filler.
The second filler 2-6 is DAI-EC Alloy filler material, which is a novel cold-resistant elastomer material with good cold resistance, compression resistance and permanent deformation.

It is an austenite precipitation strengthening high elastic alloy of Fe-Ni-Cr system. After solution treatment, the product has good plasticity, low hardness and easy processing and forming. After solid solution or cold strain, aging treatment is carried out to obtain high mechanical property and elastic property. The alloy has the characteristics of higher strength, high elastic modulus, smaller elastic after-effect, hysteresis, weak magnetism, good corrosion resistance, thermal stability and the like, and can work under the conditions of higher temperature and larger stress or corrosive medium. 3J1 can operate below 250 ℃. The alloy can also be used at low temperature (such as near-200 ℃).
The springs 2-7 are 60W4MnBA springs and have high tensile strength, yield ratio, plasticity, toughness, hardness, elastic limit and fatigue strength. At present, quenching and medium-temperature tempering are mostly adopted in the production of the steel plate spring to obtain a uniform and fine tempered troostite structure so as to meet the requirement of the service performance of the steel plate spring.
When the utility model discloses be suitable for a structure of shocking resistance of icebreaker topside receives arbitrary direction external force and acts on sandwich panel 3-2 surface on, at first absorb some energy by its inside wave battenboard 3-1 and TPEE PVC elastomer alloy material, then spread into in the structure of shocking resistance of inside. The arch plates 2-3 arranged on the left and the right are used for bearing the energy entering the interior from the moment of impact, and play a role in stabilizing and resisting pressure. Finally, after the tooth-like compression-resistant devices 2-5, the internal elliptical compression-resistant devices 2-8 and the DAI-EC Alloy filling materials 2-6 absorb shock and absorb energy, the stress is fully dispersed, and a good shock-resistant effect is achieved.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
