All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the present invention provides a ship, including a hull 1, a side 2, and a keel assembly 3 disposed on the hull 1, where the keel assembly 3 at least includes a longitudinal keel 31 disposed along a longitudinal extension of the hull 1, and a transverse keel 32 disposed along a transverse extension of the hull 1 and intersecting the longitudinal keel 31, and each longitudinal keel 31 is disposed continuously, and a notch for penetrating the longitudinal keel 31 is disposed at an intersection of each transverse keel 32 and the longitudinal keel 31. It should be further noted that, since the bottom portions of the longitudinal keels 31 and the transverse keels 32 are directly connected to the inner bottom surface of the hull 1, the notches are formed as a whole through from top to bottom.
The present invention also provides a vacuum forming method for a ship having a cross keel, as shown in fig. 3. Specifically, further explanation of the molding method is made below by preferred embodiments.
Step one, preparing a ship model: the ship model was checked, and after confirming that there was no leak point, a release agent was applied. Wherein, the new ship model needs to be coated with the release agent for 6-8 times, each time interval is 60min, and the new ship model is cured for more than 4 hours after the last coating.
Step two, spraying gel coat: before spraying, the flange edge (i.e. the counter bore of the flange edge) in the ship model is covered with paper tape, and then spraying is carried out. The spraying should ensure the uniform thickness of the gel coat at all positions in the ship model, and the thickness of the gel coat should be kept between 0.40 mm and 0.60 mm.
Step three, pasting an impermeable layer: resin is firstly dipped on a wool roller, then a chopped strand mat is paved, and burrs and the surface are polished. Wherein, the chopped strand mats should be as continuous as possible, a plurality of chopped strand mat sheets in the same layer of chopped strand mats can be connected in a lap joint mode, and the lap joint width is not less than 50 mm. After each layer of chopped strand mat is laid, a wool roller is used for dipping resin to coat the surface of the chopped strand mat, and then the next layer of chopped strand mat is laid. And the using amount of resin must be strictly controlled in the whole pasting and laying process, the whole pasting and laying process is required to be as flat as possible after the pasting and laying process is finished, no air bubbles, no glue running, no burrs and no resin accumulation exist, after the pasting and curing process, the surfaces are subjected to the removal of the left air bubbles, high aggregation points and burrs, wherein the burrs and the surfaces are polished by iron sand skins. The number of the layers of the chopped strand mats is 4-8.
Fourthly, laying of reinforcing materials: transversely and longitudinally crossed and laid, and the reinforced material is fixed by spraying glue. The reinforced materials are continuous as far as possible, reinforced sheets in the same reinforced layer are in lap joint, the lap joint width is not less than 50mm, lap joints between two adjacent reinforced layers are staggered by at least 100mm, and joints in 5 layers are not overlapped. Adjacent reinforcement layers need to be snug and not allow for buckling.
The fifth step, vertical fossil fragments and host computer seat to and laying of generator seat: prefabricating the longitudinal keels and the hardwood of the main machine base, placing aggregates, and paving the glass fiber aggregates according to the paving requirement. Wherein, longitudinal keel includes the keel structure of main joist chord side direction's longitudinal direction extension, and the main engine seat hardwood includes main engine seat and generator stand.
Sixthly, laying vacuum materials: the demoulding cloth is evenly paved in a longitudinal mode, and then the flow guide net is paved on the demoulding cloth.
Seventh step, laying a spiral pipe and a resin pipe: and longitudinally laying a spiral pipe, and sequentially inserting resin pipes on the spiral pipe. The number of the spiral pipes is multiple, the spiral pipes correspond to the extension direction one by one along the positions of the longitudinal keels, and the bottoms of the spiral pipes are communicated with one another. Of course, the plurality of spiral pipes, the flow guide net, the release cloth, and the like are integrally formed as a vacuum system.
Eighth step, vacuumizing and introducing resin: the whole vacuum system is vacuumized, the vacuum pressure is required to reach more than-0.09 MPa (namely the vacuum condition is required to be reached), and the air tightness is checked. The vertical detection of the vacuum pressure gauge requires that the integral leakage rate is not more than 2 percent after the vacuum pump is turned off for a half hour, and the vacuum pressure gauge is qualified.
Wherein the resin liquid is prepared by mixing vinyl resin and a curing agent according to the proportion of 100:1, and the resin liquid is sequentially led into the spiral pipe through the resin pipe. The whole leading-in process comprises the steps of leading resin into resin pipes communicated with spiral pipes positioned in the middle, enabling the resin to enter the spiral pipes, enabling the resin to permeate reinforcing materials in the transverse direction of a flow guide net, enabling the resin to flow to two spiral pipes adjacent to the spiral pipe in the middle along the transverse direction, inserting the resin pipes on the two adjacent spiral pipes into a prepared resin barrel, opening the two resin pipes, and closing the resin pipes of the spiral pipe in the middle (wherein when the resin pipes communicated with the spiral pipe in the middle are closed, the resin permeation condition in the spiral pipe in the middle needs to be observed, and if the resin flows slowly in a local area, the resin pipes communicated with the spiral pipe do not need to be closed, and the resin is continuously led in until the resin pipes are completely immersed); analogizing in turn, when resin soaks the next spiral pipe soon, the resin pipe of next spiral pipe intercommunication inserts in the resin bucket, opens resin pipe locking pliers and realizes the pouring of next spiral pipe, closes the last resin pipe with locking pliers simultaneously, adopts this kind of mode to constantly impel from the center to the outside and fills up every spiral pipe, soaks whole hull when resin, and every spiral pipe all fills up the back, closes all resin pipes, and the vacuum pump still will continue to take out the vacuum this moment, stops the vacuum pump when resin gel. The gel time of the resin is adjusted by adjusting the proportion of the curing agent, and the gel time is controlled to be 2-2.5h in the whole vacuum-pumping process.
Ninth step, primary gel curing and demolding: and (5) curing and molding the resin, and demolding.
Tenth step, constructing a transverse framework: the transverse framework is laid to be crossed with the longitudinal keel, and a groove is formed in the transverse framework to enable the longitudinal keel to be continuous. Meanwhile, the contact surface of the transverse framework and the contact surface of the longitudinal keel can be in contact with each other in the construction of the whole transverse framework, so that the transverse framework and the longitudinal keel can be tightly bonded to form a whole after filling, and meanwhile, the whole transverse framework is also formed into a vacuum system.
The tenth step, secondary adhesive bonding curing and demolding: the transverse framework is filled in the same way, and after the joint of the transverse keel and the longitudinal keel is bonded, the bonding is cured, and the whole ship structure is separated from the ship model, so that the ship is molded. The whole demoulding process is carried out after the reinforcing material and the compartment plate are formed and installed and the Babbitt hardness is more than or equal to 40.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
