Detailed Description
The invention is further illustrated by the following examples.
The invention designs a foldable and unfoldable double-layer large inflatable palace lantern which can be used for celebration activities. The inflatable palace lantern adopts a double-layer design and comprises an outer covering, an inner container, a mooring rope and the like. The strength of the outer skin supporting structure and appearance decoration are carried out; the design of the multilayer airtight inner container provides airtight reliability, and ensures that the palace lantern can be used for a long time; and the mooring rope and the ground mooring point perform fixed-point mooring. The inflatable palace lantern made of flexible materials can be folded and stored conveniently, can be unfolded quickly by filling helium gas during use, has beautiful and elegant decorative effect after being inflated, and can bring good atmosphere baking effect to large-scale celebration activities.
The outer skin is used as a main showing and force bearing part and is formed by sewing a textile material, and the appearance is sewn or bonded with an ornament, so that the appearance and the strength of the lantern are ensured to meet the requirements; the inner container is positioned inside the outer skin, mainly plays a role of air tightness and is formed by heat sealing of a composite film material; the inflatable palace lantern is connected with a ground mooring point through the mooring rope, and is used for fixing the palace lantern and providing certain wind resistance. The inflatable palace lantern is shown in figure 1.
The main body shape of the outer skin is an ellipsoid formed by rotating an ellipse around a vertical central axis. The outer skin material is generally coated nylon silk, the main color of the outer skin material is red at happy occasion, the outer skin material is formed by sewing and splicing 16-48 frames according to the size of the palace lantern, and a reinforcing belt is arranged between the frames, so that the outer skin material has the functions of bearing force and keel, and the appearance is more vivid. And connecting points are sewn at the maximum diameter position and the bottom position of the outer skin on the reinforcing belt and are used for connecting mooring ropes. The outer skin is sewed with golden decorative moire from top to bottom, 1 golden decorative strip is sewed on each reinforcing band, the top supports the holder with a low-density acrylic plate, and the holder at the bottom naturally droops for forming, so that the attractiveness is increased. The outer skin is shaped as in figure 2.
The inner container is made of multilayer composite film, and is formed by heat sealing 16-48 pieces according to the size of the palace lantern, so that enough air tightness can be ensured. The size of the inner container should exceed the corresponding size of the outer skin by 3%, the preferable value is 3% -10%, the inner container is too small in size and is easy to bear force before the outer skin, the inner container is damaged, and the inner container is too large in size and is poor in fit with the outer skin, and wrinkles are easy to occur. The elongation rate of the selected liner material is larger than that of the outer skin, so that when the palace lantern is inflated and expanded, the outer skin bears the force, the force of the liner is small, and the structural airtight stability of the liner is ensured. The top of the inner container is thermally sealed with a connecting point for connecting and fixing with the inner side of the top of the outer skin. The structure of the inner container is schematically shown in figure 3.
The inner bag is in the use, can take place the friction with outer covering often, so the inner bag surface also need have certain wearability when guaranteeing the gas tightness, so the inner bag divide into the three-layer, and outmost select for use comparatively firm nylon composite film, but the gas tightness is slightly poor, and two-layer PE composite film of fine and close laminating is selected for use to the inboard, and the gas tightness is high but not wear-resisting, and two-layer each other is backup.
In order to prevent residual gas from remaining between the airtight films, local bulges appear after inflation forming, and therefore the appearance display effect is influenced. A few of air holes are formed in staggered positions on the outer nylon composite film, so that residual gas can be extruded out during folding, and after inflation, the inner side and the outer side without residual gas are attached under the action of gas expansion force, and the airtight reliability of multilayer margin design is guaranteed.
In order to ensure that residual gas is positioned and extruded in a short time, the area sum of the air holes and the area ratio of the whole nylon composite film is St/Sb＝1/105And the area of a single air hole is not more than 10cm2The strength and the air tightness of the ball body can be obviously reduced when the area of the air holes is too large; the air holes are uniformly distributed on the surface of the ball body, so that the positioning and the gas extrusion are convenient. For example, every 10m of the surface of the nylon composite film is penetrated outside2Uniformly distributed 1 piece by 1cm2Big and small air holes. Therefore, when residual gas is found in the using process, the positioning and the extrusion of the residual gas can be ensured within 5 minutes; and the size and the number of the holes do not influence the strength and the air tightness of the material body.
The mooring rope is used for fixing the inflatable palace lantern and the ground mooring point. The mooring rope is generally made of light-weight and high-strength aramid fiber rope, PE rope and the like. The mooring rope can be divided into a primary mooring rope and a secondary mooring rope. The main mooring ropes 1 are gathered at multiple points through the bottom connection point of the outer skin and then fixed with the ground, the buoyancy of the inflatable palace lantern can be balanced, the inflatable palace lantern is suspended at a certain height, and the length of the main mooring ropes is determined by the suspension height of the inflatable palace lantern. The auxiliary mooring ropes can be symmetrically distributed and are tied by three points, as shown in fig. 4, the auxiliary mooring ropes are respectively fixed on the outer skin reinforcing belt and are adjacent to 2 connecting points F and 1 bottom connecting point E, and then the auxiliary mooring ropes are fixedly connected with the ground after being gathered. Through adjusting the rope length that 3 points were moored, can make the atress direction of vice rope of mooring pass through the centroid of lantern, not only avoided the atress on the outer covering to concentrate, guaranteed simultaneously to aerify palace lantern stability under the gust condition. The number and the length of the auxiliary mooring ropes are determined by the suspension height of the inflatable palace lantern and the wind power condition of the celebration field.
The stress of the palace lantern in the floating process in the air can be calculated according to a space concurrent force system, the force on the mooring rope can be synthesized, the space concurrent force system can be simplified into a plane concurrent force system, and the stress condition of the palace lantern in any wind direction is shown in figure 5.
FbAs buoyancy, FqAerodynamic forces due to horizontal wind, F1Is the resultant force of the two; fs1And Fs2To tie down the force of the rope, F2Is the resultant of the two. When the palace lantern is in the air, there is F1＝F2。
When the wind is small, F2Is within the included angle alpha of the mooring rope system, the palace lantern is kept still in the air, as shown in figure 6.
When the wind power increases to a certain degree, F2Will exceed the range of the included angle alpha, causing the force of the mooring rope on one side to be 0 and to be loose, and the lower head of the palace lantern to generate a larger displacement, as shown in fig. 7, the relationship can be obtained
s is the mooring span and h is the palace lantern pressure core height.
According to the force analysis, for example, the east-west width of the usable space of the east-west side of the square is 30m, and the north-south length is 767 m. As can be seen from Table 1, when the floating height of the palace lantern is 22.5m, and the mooring span of things is 30m, the capability of resisting wind power of more than three levels can be achieved.
TABLE 1 wind force applied to palace lantern under different wind force and mooring span required for stabilization
In order to stabilize the system, the force direction of the mooring rope must pass through the centroid of the palace lantern, and the centroid is close to the centroid because the palace lantern is symmetrical, namely the elongation line of the mooring rope passes through the centroid O (as shown in fig. 8). Because the strength of the mooring rope is higher than that of the outer skin material, in order to avoid stress concentration on the outer skin, the mooring rope is fixed on the outer skin in a three-point connection mode. The tying points are selected from three points including two points above and one point below: the point E is positioned at the intersection of the upper edge of the lower holder and the radial belt; F. f' is positioned on the equator and the diameter of the palace lanternAnd the belt is intersected (the radial belt is a local reinforced part of the outer skin, so that the stress is better). Point A is the ground tie point, point I is on the OA line, and then according to
And
the specific location of three fixing points on the outer skin can be determined.
The volume of the large celebration palace lantern is large, such as the diameter of the palace lantern is 5m, and the inflation volume is 70m3. Due to the layered design of the inner container and the outer skin, if the inner container and the outer skin are dislocated during inflation, the appearance is distorted and deformed, and the display effect is affected. Therefore, the inner container and the outer skin need to be connected and fixed, and dislocation is avoided. If the number of the connecting points is too large, on one hand, the workload is increased, and on the other hand, the connecting points are stressed intensively, so that the appearance is influenced by the depression. And set up the tie point and can not cause the concave point in the vision on the top, simultaneously in top and bottom (there is the inflation inlet bottom, connect the inflation equipment and be in fixed state during the inflation) fixed back, under the effect of gas expansion power, inner bag and outer covering are laminated the effect better naturally.
The inner container and the outer covering are respectively unfolded and laid. Four buckles are arranged on the outer side of the top of the inner container, and one buckle is arranged on the inner side of the top of the outer skin (the strength of the material of the inner container is 1/4 which is about the strength of the outer skin, so four buckles are arranged) as shown in fig. 9. When the inner container is connected with the outer skin, the inner container is firstly placed in the outer skin, the connecting rope sequentially penetrates through the 4 buckle loops at the top of the inner container, and then the buckle loops at the top of the inner container are connected with the buckle loops at the top of the outer skin through the connecting rope. Is tied with 3 flat knots. The ends were rubberized. 2, respectively supporting the top and the bottom of the outer skin, and straightening the outer skin and the inner container.
After assembly, a pre-inflation can be performed, and the outer skin and the inner container can be attached to each other in advance by the air expansion force, as shown in fig. 10. After the pre-inflation is finished, the inflatable palace lantern can be folded and packaged.
Folding process of the inflatable palace lantern: exhausting, flatly laying, folding, squeezing air and curling.

curling: finally, the liner is folded in a Z shape with the length of 1 meter, as shown in figure 12.
And (4) placing the folded inflatable palace lantern into a packaging box, and then storing.
Because the large palace lantern is bulky, need many people to cooperate and accomplish the inflation development process. 2 inflation personnel are responsible for gas source inflation and pressure gauge interpretation; the bottom nursing staff 2 are responsible for fixing the bottom of the palace lantern during inflation and sealing the air inlet after the palace lantern is fully inflated; a plurality of lateral caregivers fix the lateral direction of the palace lantern during inflation, and fix the mooring belt after the palace lantern is fully inflated; and 2 top nursing personnel are responsible for fixing the top of the palace lantern during inflation.
