The invention discloses a technical scheme for solving the problems of large volume after shrinkage and damage to articles to be protected in the process of shrinkage, which comprises the following steps: the square flexible shed roof realizes the standard folding in the transverse direction and the longitudinal direction through a mechanical device.
The specific method comprises the following steps: the mechanical device for the standard folding of the flexible shed top comprises a plurality of main beams, a plurality of folding mechanisms and a plurality of folding mechanisms, wherein the main beams are provided with main beam hinges at two ends and are arranged in a zigzag mode along the longitudinal central axis of the flexible shed top, and the main beams are connected end to end through the main beam hinges; the rotation axis of the main beam hinge is vertical to the installation plane of the flexible shed top; the included angle between the main beam and the longitudinal central axis of the flexible shed top is 1-30 degrees when the flexible shed top is in an extension state. And a fixed guide rod and a movable guide rod which respectively extend towards the two sides of the main beam along the transverse direction are arranged at the hinge of each main beam. The top of the flexible shed is provided with a rigid folding piece along the transverse direction corresponding to the positions of the fixed guide rod and the movable guide rod, and the rigid folding piece is provided with a fixed guide rod mounting hole and a movable guide rod mounting hole. The fixed guide rod and the movable guide rod respectively penetrate through the corresponding fixed guide rod mounting hole and the corresponding movable guide rod mounting hole towards the two sides of the main beam along the transverse direction, and then the fixed guide rod shed top connecting point and the movable guide rod shed top connecting point which are positioned at the ends of the fixed guide rod mounting hole and the movable guide rod shed top connecting point are respectively fixedly connected with the corresponding positions on the two longitudinal edges of the flexible shed top. The fixed guide rod shed top connecting point can move along the fixed guide rod; the connecting point of the shed top of the movable guide rod is fixedly arranged at the end head of the movable guide rod. The other end of the fixed guide rod is fixedly connected with the main beam hinge rotating shaft; the movement guide bar slides relative to the main beam hinge. The main beams can independently rotate around the main beam hinge rotating shaft between the main beams and the fixed guide rod.
The flexible shed roof may be collapsed in the following manner.
The first method is as follows: and a set of girder hinge electromechanical module is arranged on each girder hinge and used for controlling the rotation of the girder, the movement of a fixed guide rod shed top connection point on the fixed guide rod and the sliding of the movable guide rod relative to the girder hinge. When the flexible shed top needs to be folded in a contracting mode, the plurality of main beam hinge electromechanical modules simultaneously control the fixed guide rod shed top connection points on the fixed guide rods to move towards the main beam hinge direction along the transverse direction, control the movable guide rods to do movement along the transverse direction opposite to the movement direction of the fixed guide rod shed top connection points, and drive the movable guide rod shed top connection points on the movable guide rods to move towards the main beam hinge direction, so that the longitudinal two edges of the flexible shed top are driven to respectively draw close from the two sides to the middle main beam. In the process that the longitudinal two edges of the flexible shed top are drawn close to the main beam, the hard folding pieces which are originally transversely and straightly arranged are changed into zigzag arrangement, so that the flexible shed top is driven to be transversely and normally folded. When the flexible shed top is transversely folded and closed from two sides to the middle main beam in a standard manner, the main beam hinge electromechanical module controls the main beams to rotate mutually so as to enable the main beams to contract in a zigzag manner along the longitudinal central axis of the flexible shed top, and thus the transversely folded flexible shed top is driven to be longitudinally folded in a standard manner. And after the main beams of all the sections are contracted and closed, the flexible shed top is folded according to the specification.
Furthermore, in the structure that the electrical module is arranged on the main beam hinge, the standard folding process of the flexible shed top is reversely carried out, namely the standard extending process of the flexible shed top.
Furthermore, in the structure of installing the electromechanical module on the girder hinge, the transverse standard folding and the longitudinal standard folding of the flexible shed top can be carried out by time intervals and simultaneously, namely, the flexible shed top is transversely folded and closed from two sides to the middle girder, and simultaneously, each section of girder contracts in a zigzag manner along the longitudinal central axis of the flexible shed top to carry out the longitudinal standard folding.
Furthermore, in the structure of mounting the electrical module on the main beam hinge, the extension and retraction of each section of main beam can be performed simultaneously or sequentially. When each section of girder stretches out and draws back in proper order, the folding and vertical folding of standardizing of horizontal standard need be gone on in the time sharing section.
Further, in the structure in which the electrical module is mounted on the main beam hinge, the flexible ceiling mounting plane can be deflected at the main beam hinge with the ceiling mounting plane transverse axis as the axis by changing the mounting angle of a main beam hinge rotating shaft in the middle position.
Furthermore, in the structure of installing the electromechanical module on the main beam hinge, one main beam hinge or the main beam is connected with a base fixing point on other objects, and one of the main beam hinge and the main beam is optionally connected with the base fixing point.
Further, in the structure of installing the electromechanical module on the hinge of the main beam, in the case of needing to enhance the wind resistance, additional fixing points are added at the far end of each section of the main beam after extending. The additional fixed points can be connected with the main beams after the main beams at all sections are extended, and can be separated when all sections of the main beams are contracted.
The second method comprises the following steps: and a torsion spring is arranged on a main beam hinge connected with the main beam. The extension of each section of main beam along the longitudinal central axis of the flexible shed top is against the elasticity of the torsion spring; each section of main beam contracts in a zigzag manner along the longitudinal central axis of the flexible shed top and leans against the tension of the main beam pull rope. The movement of the fixed guide rod shed top connection point on the fixed guide rod and the sliding of the movable guide rod relative to the main beam hinge are controlled by the guide rod pull rope. When the flexible shed top needs to be contracted and folded, the guide rod pull rope controls the fixed guide rod shed top connection point on the fixed guide rod to move towards the direction of the main beam hinge along the transverse direction, controls the movable guide rod to transversely move in the direction opposite to the movement direction of the fixed guide rod shed top connection point, and drives the movable guide rod shed top connection point on the movable guide rod to move towards the direction of the main beam hinge, so that the longitudinal two edges of the flexible shed top are driven to respectively draw close from the two edges to the middle main beam. In the process that the longitudinal two edges of the flexible shed top are drawn close to the main beam, the original hard folding pieces which are transversely and straightly arranged along the rice are changed into zigzag arrangement, so that the flexible shed top is driven to be transversely and normally folded. When the flexible shed top is transversely folded and closed from two sides to the middle main beam in a standard way, the pull ropes of the main beams pull the main beams to enable the main beams to contract in a zigzag way along the longitudinal central axis of the flexible shed top, so that the transversely folded flexible shed top is driven to be longitudinally folded in a standard way. And after the main beams of all the sections are contracted and closed, the flexible shed top is folded according to the specification.
Furthermore, in the structure of installing the torsion spring on the main beam hinge, the standard folding process of the flexible shed top is reversely carried out, and the standard extending process of the flexible shed top is realized.
Furthermore, in the structure that the torsion spring is arranged on the main beam hinge, the control of the main beam pull rope and the guide rod pull rope can be completed by a pull rope control electromechanical module or manually.
Further, in the structure of installing torsion spring on the girder hinge, the horizontal standard of gentle matter shed roof is folding can be gone on with vertical standard is folding by the time quantum, also can go on simultaneously, and each section girder is the zigzag shrink along the vertical axis of gentle matter shed roof and carries out vertical standard folding when the girder from both sides to the centre of gentle matter shed roof is folding to be drawn close to from horizontal standard promptly.
Furthermore, in the structure that the torsion spring is installed on the main beam hinge, the extension and retraction of each section of main beam can be carried out simultaneously, and the extension and retraction of each section of main beam can be carried out sequentially by adjusting the elasticity of the torsion spring. When each section of girder stretches out and draws back in proper order, the folding and vertical folding of standardizing of horizontal standard need be gone on in the time sharing section.
Further, in the structure in which the torsion spring is mounted on the main beam hinge, by changing the mounting angle of a main beam hinge rotating shaft at the intermediate position, the flexible ceiling mounting plane can be deflected at the main beam hinge with the ceiling mounting plane transverse axis as the axis.
Further, in the structure of installing the torsion spring on the main beam hinge, one main beam hinge or the main beam is connected with a foundation fixing point on other objects, and one of the main beam hinge and the main beam is optionally connected with the foundation fixing point.
Further, in the structure of installing the torsion spring on the main beam hinge, under the condition that the wind resistance is required to be enhanced, additional fixing points are added at the far end of each section of the main beam after being extended. The additional fixed points can be connected with the main beams after the main beams at all sections are extended, and can be separated when all sections of the main beams are contracted.
The third method comprises the following steps: a group of secondary beams are arranged at the mirror image positions of the sections of the main beams, which take the longitudinal central axis of the flexible shed roof as the axis, secondary beam hinges are arranged at the two ends of the secondary beams, the secondary beams are connected end to end through the secondary beam hinges, and the rotation axis of the secondary beam hinges is perpendicular to the mounting plane of the flexible shed roof. The middle point of the auxiliary beam and the middle point of the main beam are connected through a middle hinge, and the rotation axis of the middle hinge is vertical to the mounting plane of the top of the flexible shed. The main beam and the auxiliary beam form a series-connected shear fork structure through a main beam hinge, an auxiliary beam hinge and a middle hinge. In the series-connected scissors fork structure, a pulley and a pulley pull rope are arranged on the fixed guide rod, an auxiliary beam hinge connection point and a fixed guide rod shed top connection point are respectively arranged at corresponding positions on the pulley pull rope, and the auxiliary beam hinge connection point and the fixed guide rod shed top connection point on the pulley pull rope are respectively connected with an auxiliary beam hinge rotating shaft and the corresponding positions on the longitudinal edge of the flexible shed top. One end of the fixed guide rod is fixedly connected with the main beam hinge rotating shaft. The auxiliary beam hinge connection point on the pulley pull rope and the fixed guide rod shed top connection point do mirror image relative movement when in use. When the auxiliary beam hinge connection point is positioned at one end of the fixed guide rod far away from the main beam hinge, the fixed guide rod shed top connection point is positioned at one end of the fixed guide rod close to the main beam hinge; when the auxiliary beam hinge connection point moves towards one end of the fixed guide rod close to the main beam hinge, the fixed guide rod shed top connection point moves towards one end of the fixed guide rod far away from the main beam hinge; when the auxiliary beam hinge joint moves to the end, close to the main beam hinge, of the fixed guide rod, the fixed guide rod shed top joint moves to the end, far away from the main beam hinge, of the fixed guide rod. In the series-connected scissors structure, one end of a movable guide rod is fixedly connected with a hinge rotating shaft of the auxiliary beam, and the other end of the movable guide rod is connected with the corresponding position of the longitudinal edge of the flexible shed top through a shed top connecting point of the movable guide rod on the movable guide rod. When the flexible shed roof needs to be contracted and folded, the main beam and the auxiliary beam are rotated to enable the main beam hinge and the auxiliary beam hinge to respectively move towards the direction far away from the longitudinal central axis of the flexible shed roof, so that the serially connected shear fork structures are contracted along the longitudinal central axis of the flexible shed roof. Under the drive of the auxiliary beam hinge, the fixed guide rod shed top connection point on the pulley pull rope and the movable guide rod shed top connection point on the movable guide rod move towards the direction close to the main beam hinge, so that the longitudinal two edges of the flexible shed top are driven to respectively approach the main beam in the middle from the two edges. In the process that the longitudinal two edges of the flexible shed top are drawn close to the main beam, the hard folding pieces which are originally transversely and straightly arranged are changed into zigzag arrangement, so that the flexible shed top is driven to be transversely and normally folded. When the flexible shed top is transversely folded from two sides to the middle girder in a standard way, all sections of girders shrink in a zigzag way along the longitudinal central axis of the flexible shed top, namely the transverse standard folding and the longitudinal standard folding of the flexible shed top are carried out simultaneously. When the main beams of each section are contracted and closed, the transverse standard folding and the longitudinal standard folding of the flexible shed top are finished simultaneously.
Furthermore, in the series-connected scissors structure, the standard folding process of the flexible shed top is reversely carried out, namely the standard stretching process of the flexible shed top.
Furthermore, in the tandem scissors structure, the rotation of the main beam and the auxiliary beam can be completed by the scissors electromechanical module or manually.
Furthermore, in the tandem scissors structure, the flexible shed roof installation plane can deflect by taking the transverse axis of the shed roof installation plane as the axis at the transverse section vertical to the longitudinal central axis of the flexible shed roof through changing the installation angles of a pair of main beam hinge rotating shafts and auxiliary beam hinge rotating shafts which are positioned at the same transverse section vertical to the longitudinal central axis of the flexible shed roof. The axes of the main beam hinge rotating shaft and the auxiliary beam hinge rotating shaft are subjected to mirror image deflection in a transverse section perpendicular to the longitudinal central axis of the flexible shed roof, namely the deflection angles are the same and the directions are opposite.
Furthermore, in the tandem scissors structure, the transverse storage space can be effectively utilized under the condition that the fixed guide rod and the movable guide rod are as long as the main beam, namely, the width of the flexible shed top is the largest after the flexible shed top is extended under the condition of the same transverse storage space width.
Furthermore, in the tandem scissors structure, a main beam hinge or a middle hinge or a main beam is connected with a base fixing point on other objects. One of the three optional parts is connected with the basic fixed point.
Further, in the tandem scissors structure, an additional fixing point is added at the far end of the tandem scissors structure after stretching under the condition that the wind resistance is required to be enhanced. The additional fixing point can be connected with the scissors structure in series after being extended and can be disconnected when being contracted.

Detailed Description
The first embodiment is as follows: and a set of girder hinge electromechanical modules 2 are arranged on each girder hinge 6 and used for controlling the rotation of the girder 1, the movement of the fixed guide rod shed top connection point 4 on the fixed guide rod 3 and the sliding of the movable guide rod 5 relative to the girder hinge 6. When the flexible shed top 8 needs to be folded, the plurality of main beam hinge electromechanical modules 2 simultaneously control the fixed guide rod shed top connection points 4 on the fixed guide rods 3 to move towards the main beam hinges 6 along the transverse direction and control the movable guide rods 5 to do movement along the transverse direction, wherein the movement direction is opposite to the movement direction of the fixed guide rod shed top connection points 4, and the movable guide rod shed top connection points 7 on the movable guide rods 5 are driven to move towards the main beam hinges 6, so that the longitudinal two edges of the flexible shed top 8 are driven to respectively approach the main beam 1 in the middle from the two edges. In the process that the longitudinal two edges of the flexible shed top 8 are drawn close to the main beam 1, the hard folding pieces 9 which are originally transversely and straightly arranged are changed into zigzag arrangement, so that the flexible shed top 8 is driven to be transversely and normally folded. When the flexible shed top 8 is transversely folded and closed from two sides to the middle main beam 1 in a standard manner, the main beam hinge electromechanical module 2 controls the main beam 1 sections to rotate mutually, so that the main beam 1 sections shrink in a zigzag manner along the longitudinal central axis of the flexible shed top, and the transversely folded flexible shed top 8 is driven to be longitudinally folded in a standard manner. And after the main beams 1 of all the sections are contracted and closed, the flexible shed top 8 is folded according to the specification, and then the folding is finished. The standard folding process of the flexible shed roof 8 is reversely carried out, namely the standard extending process of the flexible shed roof 8.
Example two: a torsion spring 10 is arranged on a main beam hinge 6 connecting the main beam 1 and the main beam 1. The extension of each section of main beam 1 along the longitudinal central axis of the flexible shed top is against the elasticity of the torsion spring 10; each section of main beam 1 contracts in a zigzag manner along the longitudinal central axis of the flexible shed top and leans against the tension of the main beam pull rope 11. The movement of the fixed guide rod shed top connection point 4 on the fixed guide rod 3 and the sliding of the movable guide rod 5 relative to the girder hinge 6 are controlled by a guide rod pull rope 12. When the flexible shed top 8 needs to be folded, the guide rod pull rope 12 controls the fixed guide rod shed top connection point 4 on the fixed guide rod 3 to move towards the main beam hinge 6 along the transverse direction, controls the movable guide rod 5 to do movement along the transverse direction opposite to the movement direction of the fixed guide rod shed top connection point 4, and drives the movable guide rod shed top connection point 7 on the movable guide rod 5 to move towards the main beam hinge 6, so that the longitudinal two edges of the flexible shed top 8 are driven to respectively draw close from the two edges to the main beam 1 in the middle. In the process that the longitudinal two edges of the flexible shed top 8 are drawn close to the main beam 1, the hard folding pieces 9 which are originally transversely and straightly arranged are changed into zigzag arrangement, so that the flexible shed top 8 is driven to be transversely and normally folded. After the flexible shed top 8 is transversely folded and drawn close to the main beam 1 in the middle from two sides in a standard way, the main beam pull rope 11 pulls the main beam to ensure that each section of the main beam 1 contracts in a zigzag way along the longitudinal central axis of the flexible shed top, so that the transversely folded flexible shed top 8 is driven to be longitudinally folded in a standard way. And after the main beams 1 of all the sections are contracted and closed, the flexible shed top 8 is folded according to the specification, and then the folding is finished. The control of the main beam pull rope 11 and the guide rod pull rope 12 is completed by a pull rope control electromechanical module 13. The standard folding process of the flexible shed roof 8 is reversely carried out, namely the standard extending process of the flexible shed roof 8.
Example three: a group of auxiliary beams 14 are arranged at the mirror image positions of the sections of the main beams 1 with the longitudinal central axis of the flexible shed top as the axis, auxiliary beam hinges 15 are arranged at the two ends of each auxiliary beam 14, the auxiliary beams 14 are connected end to end through the auxiliary beam hinges 15, and the rotation axis of each auxiliary beam hinge 15 is perpendicular to the mounting plane of the flexible shed top. The middle point of the secondary beam 14 is connected with the middle point of the main beam 1 through a middle hinge 16 with the rotation axis vertical to the installation plane of the flexible shed top. That is, the main beam 1 and the auxiliary beam 14 form a series-connected scissor fork structure through the main beam hinge 6, the auxiliary beam hinge 15 and the middle hinge 16.

One end of the fixed guide rod 3 passes through the fixed guide rod mounting hole 30 and is fixedly connected with the main beam hinge rotating shaft 21. The secondary beam hinge connection point 19 on the pulley pull rope 18 and the fixed guide rod shed roof connection point 4 do mirror image relative movement when in use. Namely, when the auxiliary beam hinge connection point 19 is positioned at one end of the fixed guide rod 3 far away from the main beam hinge 6, the fixed guide rod shed top connection point 4 is positioned at one end of the fixed guide rod 3 close to the main beam hinge 6; when the auxiliary beam hinge connection point 19 moves towards one end of the fixed guide rod 3 close to the main beam hinge 6, the fixed guide rod shed top connection point 4 moves towards one end of the fixed guide rod 3 far away from the main beam hinge 6; the fixed guide bar ceiling connection point 4 moves to the end of the fixed guide bar 3 away from the main beam hinge 6 when the secondary beam hinge connection point 19 moves to the end of the fixed guide bar 3 near the main beam hinge 6. In the series-connected scissors structure, one end of the movable guide rod 5 penetrating through the movable guide rod mounting hole 31 is fixedly connected with the auxiliary beam hinge rotating shaft 20, and the other end is connected with the corresponding position of the longitudinal edge of the flexible shed roof through the movable guide rod shed roof connecting point 7 on the movable guide rod 5. When the flexible shed roof 8 needs to be contracted and folded, the shearing fork electromechanical module 22 pushes the main beam 1 and the auxiliary beam 14 to rotate, the main beam hinge 6 and the auxiliary beam hinge 15 respectively move towards the direction far away from the longitudinal central axis of the flexible shed roof, and the shearing fork structures connected in series contract along the longitudinal central axis of the flexible shed roof. Under the drive of the auxiliary beam hinge 15, the fixed guide rod shed top connection point 4 on the pulley pull rope 18 and the movable guide rod shed top connection point 7 on the movable guide rod respectively move from two sides to the main beam hinge 6, so that the longitudinal two edges of the flexible shed top 8 are driven to respectively draw close from two sides to the main beam 1 in the middle. In the process that the longitudinal two edges of the flexible shed top 8 are drawn close to the main beam 1, the hard folding pieces 9 which are originally transversely and straightly arranged are changed into zigzag arrangement, so that the flexible shed top 8 is driven to be transversely and normally folded. When the flexible shed roof 8 is transversely folded and closed from two sides to the middle main beam 1 in a standard manner, each section of main beam 1 contracts in a zigzag manner along the longitudinal central axis of the flexible shed roof, namely, the transverse standard folding and the longitudinal standard folding of the flexible shed roof 8 are carried out simultaneously. When the main beams 1 of all the sections are contracted and closed, the transverse standard folding and the longitudinal standard folding of the flexible shed top 8 are finished simultaneously. The standard folding process of the flexible shed roof 8 is reversely carried out, namely the standard extending process of the flexible shed roof 8.
