Description

Technical Field

[0001] The present application relates to the technical field of steel structure roofs, and in particular to a steel structure building roof and its construction method. Background Art

[0002] A steel structure building roof generally refers to a roof with a load-bearing structure composed of building steel, which has the characteristics of high strength, short construction period, good seismic performance, etc.

[0003] In the related art, a steel structure building roof mainly includes a support frame and a horizontal plate installed at the top of the support frame. Support columns are arranged on the horizontal plate. Diagonal beams are obliquely arranged between the two sides of the support columns and the horizontal plate. Roof panels are arranged on the diagonal beams. The support frame is installed on the ground, then the horizontal plate is installed at the top of the support frame, then the support columns are installed on the upper surface of the horizontal plate, the diagonal beams are installed on the support columns, and finally the roof panels are installed on the diagonal beams to complete the installation of the roof.

[0004] In view of the above related art, when it rains, the rain hitting the steel roof panel will make a relatively loud noise, seriously affecting people's rest. Summary of the Invention

[0005] In order to reduce the noise generated by rain hitting the roof panel and not easily affect people's rest, the present application provides a steel structure building roof and its construction method.

[0006] In a first aspect, a steel structure building roof provided by the present application adopts the following technical solution:

[0007] A steel structure building roof includes roof panels on both sides. Rotating rods are rotatably arranged on one side of the two roof panels close to each other. The rotation axis of the rotating rod is parallel to the length direction of the roof panel. A flexible cloth is wound around the rotating rod. A driving member is arranged on the rotating rod to drive the rotating rod to wind up the flexible cloth. Guide blocks are respectively arranged on both sides of the end of the flexible cloth far from the rotating rod. The guide blocks slide on the corresponding roof panel. The sliding direction of the guide blocks is parallel to the inclined direction of the roof panel. A pulling assembly is arranged on the roof panel to pull the guide blocks to slide in a direction away from the rotating rod.

[0008] By adopting the above technical solution, the pulling assembly pulls the guide blocks to slide in a direction away from the rotating rod, so that the guide blocks pull the flexible cloth to move. The flexible cloth drives the rotating rod to rotate and unwind the flexible cloth, so that the flexible cloth covers the surface of the roof panel. When it rains, the rain falls on the flexible cloth, which can reduce the sound generated by the rain hitting, and thus not easily affect people's rest. After the rain stops, the driving member drives the rotating rod to wind up the flexible cloth, which helps to store the flexible cloth and prevent fallen leaves and other sundries from falling onto the flexible cloth.

[0009] Preferably, the pulling assembly includes a guiding pulley disposed on the guiding block, a pulling rope slidably lapped on the guiding pulley, and a pulling member disposed on the side of the roof panel away from the corresponding rotating rod. The pulling members correspond to the pulling ropes one by one. One end of the pulling rope is disposed on the side of the roof panel away from the corresponding rotating rod, and the other end is connected to the corresponding pulling member. The pulling member is used to pull or release the pulling rope.

[0010] By adopting the above technical solution, the pulling member pulls the pulling rope, and the pulling rope pulls the guiding block to move away from the rotating rod through the guiding pulley, which helps to pull the flexible cloth to cover the roof panel. Therefore, when rain falls, it is not easy for the rain to directly strike the roof panel and make a huge noise, reducing the impact on people's rest. At the same time, the cooperation between the guiding pulley and the pulling rope helps to reduce the pulling force required to pull the pulling rope, thus achieving the effect of saving effort.

[0011] Preferably, the pulling member includes a winding drum rotatably disposed on the roof panel, a gear coaxially sleeved on the winding drum, a water collecting cylinder disposed on the roof panel, a floating plate slidably disposed in the water collecting cylinder, and a rack disposed on the floating plate. The winding drum is located on the side of the roof panel away from the corresponding rotating rod. The end of the pulling rope away from the roof panel is wound around the winding drum. The sliding direction of the floating plate is perpendicular to the rotation axis of the winding drum. The rack is used to engage with the gear. When the rack moves upward, the gear drives the winding drum to rotate to wind up the pulling rope.

[0012] By adopting the above technical solution, when it rains, the rainwater in the water collecting cylinder gradually increases, and the rising water level drives the floating plate and the rack to move upward. The upward movement of the rack drives the corresponding gear to rotate, causing the winding drum to rotate to wind up the pulling rope. Therefore, it is convenient to make the pulling rope pull the guiding block to slide away from the rotating rod, which helps to cover the roof panel with the flexible cloth when it rains, reducing the noise generated by the rain hitting and not easily affecting people's rest. The movement of the rack driven by the rainwater during rain does not require manual adjustment, which is simple and convenient.

[0013] Preferably, a water receiving groove is disposed on the side of the roof panel away from the rotating rod. The side of the roof panel away from the rotating rod is connected to the water receiving groove. The water receiving groove is located between the water collecting cylinders on both sides of the roof panel, and the corresponding ends of the water collecting cylinders are connected to the water receiving groove.

[0014] By adopting the above technical solution, the setting of the water receiving groove helps to collect the rainwater on the roof panel, thereby accelerating the upward movement speed of the rack and helping to drive the guiding block to move toward the rotating rod in a timely manner.

[0015] Preferably, a through hole is formed in the bottom wall of the water collecting cylinder, and the diameter of the through hole is less than 1 mm.

[0016] By adopting the above technical solution, after the rain stops, the rainwater in the water collecting cylinder gradually flows out through the through hole, so as to facilitate the driving member to drive the rotating rod to wind up the flexible cloth in a timely manner.

[0017] Preferably, a protective cover is provided on the roof panel, the rotating rod rotates within the corresponding protective cover, an opening for the guide block and the flexible cloth to slide in or out is formed on one side of the protective cover close to the corresponding winding drum, an opening and closing plate for opening and closing the opening is rotatably provided on the protective cover, the rotation axis of the opening and closing plate is parallel to the length direction of the roof panel, and a rotating assembly for driving the opening and closing plate to rotate towards or away from the opening is provided on the protective cover.

[0018] By adopting the above technical solution, the rotating assembly drives the opening and closing plate to rotate away from the opening, opening the opening, so as to facilitate the guide block to drive the flexible cloth to move out of the protective cover to cover the roof panel; the rotating assembly drives the opening and closing plate to rotate towards the opening, which helps to protect the flexible cloth on the rotating rod and reduce the possibility of the flexible cloth being damaged by exposure to the sun.

[0019] Preferably, a rotating shaft is provided on the opening and closing plate, the rotating shaft is rotatably provided on the protective cover, the rotating assembly includes a torsion spring sleeved on the rotating shaft, a connecting rope provided on the opening and closing plate, and a transmission member provided on the protective cover. The torsion spring is used to drive the opening and closing plate to rotate towards the opening. One end of the torsion spring is provided on the opening and closing plate, and the other end is provided on the protective cover. A guide ring is provided on the side of the protective cover away from the opening. The connecting ropes correspond to the guide blocks one by one, and the guide rings correspond to the connecting ropes one by one. The connecting ropes slide through the corresponding guide rings and extend into the protective cover. The transmission member is used to pull or loosen the corresponding connecting ropes when the guide blocks slide. When the guide blocks slide away from the rotating rod, the transmission member pulls the corresponding connecting ropes.

[0020] By adopting the above technical solution, when the guide block moves away from the rotating rod, the transmission member pulls the connecting rope to move away from the opening and closing plate, so that the opening and closing plate rotates away from the opening, opening the opening, which helps the guide block and the flexible cloth to move out; when the guide block moves into the protective cover towards the rotating rod, the transmission member loosens the connecting rope, and under the action of the torsion spring, the opening and closing plate rotates towards the opening, which helps to block the opening and protect the flexible cloth, and prolongs the service life of the flexible cloth.

[0021] Preferably, the transmission member includes a slider sliding in the protective cover, a first magnet disposed on the side of the slider close to the opening, a first iron sheet disposed on the side of the guide block close to the rotating rod, a second iron sheet disposed on the side of the slider close to the opening, and a second magnet disposed on the protective cover. The sliders and the guide blocks are in one-to-one correspondence. The sliding direction of the slider is parallel to the sliding direction of the guide block. The slider is located on the side of the corresponding guide block close to the rotating rod. One end of the connecting rope located inside the protective cover is disposed on the corresponding slider. The first iron sheet is used for adsorption cooperation with the first magnet, and the adsorption force between the first iron sheet and the first magnet is greater than the torsion force of the torsion spring. The second magnet is located on the side of the slider close to the guide block, and the second magnet is used for adsorption cooperation with the second iron sheet. The adsorption force between the second iron sheet and the second magnet is greater than the torsion force of the torsion spring.

[0022] By adopting the above technical solution, when the guide block moves in the direction away from the rotating rod, the slider is pulled to slide in the direction close to the second magnet by the adsorption force between the first magnet and the first iron sheet, so that the slider pulls the connecting rope to rotate the opening and closing plate in the direction away from the opening, which helps to open the opening. When the slider moves to the position of the second magnet, the second iron sheet and the second magnet are adsorbed and matched to limit the sliding of the slider. When the guide block continues to move, the first magnet and the first iron sheet are separated, and the adsorption force between the second magnet and the second iron sheet helps to maintain the position of the slider, so that the opening and closing plate keeps the opening open.

[0023] Preferably, the driving member includes a torsion spring for driving the rotating rod to rotate and wind the flexible cloth. The torsion spring is sleeved on the rotating rod. One end of the torsion spring is disposed on the rotating rod, and the other end is disposed on the protective cover.

[0024] By adopting the above technical solution, the torsion spring drives the rotating rod to rotate to wind the flexible cloth, which helps to store and protect the flexible cloth and reduce the accumulation of fallen leaves and other sundries on the flexible cloth.

[0025] In the second aspect, a construction method for the roof of a steel structure building provided by the present application adopts the following technical solution:

[0026] A construction method for the roof of a steel structure building uses the steel structure building roof as described above, and includes the following steps:

[0027] Step 1: Install the support frame on the ground and install the horizontal plate on the top of the support frame;

[0028] Step 2: Install the support columns on the horizontal plate and install the inclined beams on the support columns;

[0029] Step 3: Install the roof plate on the inclined beam, rotatably install the rotating rod on the roof plate, install the pulling assembly on the roof plate, and respectively dispose the side of the flexible cloth away from the rotating rod on the guide block sliding on the roof plate.

[0030] In summary, the present application includes the following beneficial technical effects:

[0031] When it rains, the rainwater in the water collecting cylinder gradually increases, and the rising water level drives the floating plate and the rack to move upward. The upward movement of the rack drives the corresponding gear to rotate, causing the reel to rotate and wind up the pulling rope. Thus, it is convenient for the pulling rope to pull the guiding block to slide away from the rotating rod, which helps to cover the roof slab with the flexible cloth when it rains, reducing the noise generated by the rain hitting and not easily affecting people's rest.

Detailed Embodiment

[0038] The following further describes the present application in detail with reference to the attached Figures 1-5 drawings.

[0039] The embodiment of the present application discloses a roof of a steel structure building. Refer to Figure 1 and Figure 2The steel structure building roof includes a roof panel 1 inclined on both sides, and a protective cover 8 is anchored on the side where the roof panels 1 on both sides are close to each other by bolts. A rotating rod 2 is rotatably arranged in the protective cover 8, and the rotating axis of the rotating rod 2 is parallel to the length direction of the roof panel 1, and the length direction of the roof panel 1 is perpendicular to the arrangement direction of the roof panels 1 on both sides. A flexible cloth 3 is wound around the rotating rod 2, and a driving member for driving the rotating rod 2 to reel in the flexible cloth 3 is arranged on the rotating rod 2. The two sides of the flexible cloth 3 away from one end of the rotating rod 2 are respectively connected with guide blocks 4 by thin ropes, and the guide blocks 4 slide on the roof panel 1. The longitudinal section of the guide blocks 4 is I-shaped, and the sliding direction of the guide blocks 4 is parallel to the inclination direction of the roof panel 1, and the sliding direction of the guide blocks 4 is perpendicular to the length direction of the roof panel 1. A guide groove 19 slidably matched with the guide blocks 4 is opened on the roof panel 1, and a pulling component 5 for pulling the guide blocks 4 to slide in a direction away from the corresponding rotating rod 2 is arranged on the roof panel 1.

[0040] Reference Figure 3 and Figure 4 An opening 9 for the guide block 4 and the flexible cloth 3 to slide in or out is provided on the side of the protective covers 8 on both sides away from each other. The cross section of the opening 9 is adapted to the longitudinal section of the protective cover 8. An opening and closing plate 10 for opening and closing the opening 9 is rotatably provided on the top wall of the protective cover 8. The rotation axis of the opening and closing plate 10 is parallel to the length direction of the roof plate 1. A rotating shaft 12 is coaxially fixed on the opening and closing plate 10. The rotating shaft 12 rotates on the top wall of the protective cover 8. A rotating component 11 is provided on the protective cover 8 for driving the opening and closing plate 10 to rotate toward or away from the opening 9.

[0041] Reference Figure 2 and Figure 3 In order to facilitate the pulling of the guide block 4 to slide in the direction away from the rotating rod 2, the pulling assembly 5 includes a guide pulley 51 fixedly installed on the side of the guide block 4 away from the corresponding rotating rod 2, a pull rope 52 slidably overlapped on the guide pulley 51, and a pulling member 53 arranged on the side of the roof board 1 away from the corresponding rotating rod 2. The pulling member 53 corresponds to the pull rope 52 one by one. One end of the pull rope 52 is fixedly connected to the side of the roof board 1 away from the corresponding rotating rod 2, and the other end is connected to the corresponding pulling member 53. The pulling member 53 is used to pull or release the pull rope 52.

[0042] Reference Figure 3 and Figure 5, a support plate 20 is fixed to the side wall of the roof plate 1 by bolts. The support plates 20 correspond to the pulling members 53 one by one. The pulling member 53 includes a winding drum 531 rotatably arranged on the corresponding support plate 20, a gear 532 coaxially and fixedly sleeved on the winding drum 531, a water collecting cylinder 533 fixedly installed on the roof plate 1 by bolts, a floating plate 534 slidably arranged in the water collecting cylinder 533, and a rack 535 arranged on the floating plate 534. The winding drum 531 is located on the side of the roof plate 1 away from the corresponding protective cover 8. The rotation axis of the winding drum 531 is parallel to the length direction of the roof plate 1. The end of the pulling rope 52 away from the roof plate 1 bypasses the corresponding guiding pulley 51 and is wound around the winding drum 531, so that the pulling rope 52 is in a V shape. The diameter of the gear 532 is smaller than that of the winding drum 531.

[0043] Referring to Figure 3 and Figure 5 , a water receiving trough 6 is fixed to the side of the roof plate 1 away from the rotating rod 2 by bolts. The longitudinal section of the water collecting trough is U-shaped. The side of the roof plate 1 away from the rotating rod 2 is located above the water receiving trough 6 and is connected to the water receiving trough 6. The water receiving trough 6 is located between the water collecting cylinders 533 on both sides of the roof plate 1. The water collecting cylinder 533 is fixed below the corresponding end of the water receiving trough 6 and the cylinder opening is connected to the end of the water receiving trough 6. The water collecting cylinder 533 is located below the winding drum 531. The cylinder opening of the water collecting cylinder 533 is arranged upward. The cross section of the floating plate 534 is smaller than that of the water collecting cylinder 533. Counterweight blocks 21 are fixed to the opposite sides of the floating plate 534. Grooves 22 slidably matched with the counterweight blocks 21 are formed on the opposite inner walls of the water collecting cylinder 533. The top end of the groove 22 is lower than the upper surface of the water collecting cylinder 533, so that the counterweight blocks 21 are not easily separated from the water collecting cylinder 533. The sliding direction of the floating plate 534 is perpendicular to the rotation axis of the winding drum 531. The rack 535 is arranged in the vertical direction and is used to mesh with the gear 532. The number of teeth on the rack 535 is more than 6 times the number of teeth on the gear 532. When the counterweight block 21 abuts against the lower end of the groove 22, the rack 535 is disengaged from the corresponding gear 532. A through hole 7 is formed in the bottom wall of the water collecting cylinder 533. The diameter of the through hole 7 is less than 1 mm. In this embodiment, the diameter of the through hole 7 is 0.8 mm. When the rack 535 moves upward, the gear 532 drives the winding drum 531 to rotate and wind up the pulling rope 52.

[0044] Referring to Figure 1 and Figure 5 , a water outlet hole 23 is formed in the side wall of the water collecting cylinder 533. The position of the water outlet hole 23 is flush with the position of the top end of the groove 22, so as to facilitate the discharge of the redundant water in the water collecting cylinder 533.

[0045] Referring to Figure 3 and Figure 4 , the driving member includes a torsion spring 14 for driving the rotating rod 2 to wind up the flexible cloth 3. The torsion spring 14 is sleeved on the rotating rod 2. One end of the torsion spring 14 is fixedly connected to the rotating rod 2, and the other end is fixedly connected to the side wall of the protective cover 8.

[0046] When it rains, the rainwater that initially falls on the roof panel 1 flows into the water collecting trough 6 and converges. Then, it flows into the water collecting cylinder 533 from both ends of the water collecting trough 6. Since the diameter of the through hole 7 is very small, the water level in the water collecting cylinder 533 rises quickly. The rainwater drives the floating plate 534 and the counterweight 21 to move upward in the direction close to the winding drum 531, causing the rack 535 to gradually engage with the corresponding gear 532. The gear 532 drives the winding drum 531 to rotate, causing the winding drum 531 to wind up the pulling rope 52. The pulling rope 52 pulls the corresponding guide block 4 to slide away from the rotating rod 2 through the guide pulley 51. At this time, the opening and closing plate 10 is driven by the rotating assembly 11 to rotate away from the opening 9, opening the opening 9. The guide block 4 pulls the flexible cloth 3 to gradually cover the roof panel 1 through the thin rope. The flexible cloth 3 drives the rotating rod 2 to rotate and unwind the flexible cloth 3 until the flexible cloth 3 completely covers the roof panel 1. The counterweight 21 slides to the top of the groove 22. At this time, the excess water in the water collecting cylinder 533 flows out through the water outlet hole 23. The falling rainwater strikes the flexible cloth 3. The flexible cloth 3 has certain water absorption and ductility, so as to reduce the noise generated by the rain hitting and is not likely to affect people's rest. The cooperation of the pulling rope 52 and the guide pulley 51 can reduce the force required to pull the pulling rope 52, so as to ensure that the floating plate 534 can move upward to drive the rack 535 to drive the gear 532 to rotate.

[0047] When the rain stops, the rainwater in the water collecting cylinder 533 gradually flows out through the through hole 7, causing the floating plate 534 to move downward under the gravity of the counterweight 21, causing the rack 535 to drive the gear 532 and the winding drum 531 to rotate to unwind the pulling rope 52. At this time, under the action of the torsion spring 14, the rotating rod 2 is driven to rotate to wind up the flexible cloth 3. The flexible cloth 3 drives the guide block 4 to slide in the direction close to the rotating rod 2 until the guide block 4 moves into the protective cover 8. The opening and closing plate 10 is driven by the rotating assembly 11 to rotate in the direction close to the opening 9, so that the opening and closing plate 10 blocks the opening 9, which helps to store and protect the flexible cloth 3, making it difficult for fallen leaves and other sundries to fall onto the flexible cloth 3. At the same time, the flexible cloth 3 is not easily exposed to the sun, which helps to extend the service life of the flexible cloth 3; at the same time, no manual operation is required, which is simple and convenient.

[0048] Refer to Figure 3 and Figure 4, to facilitate driving the opening and closing plate 10 to rotate towards or away from the opening 9, the rotating assembly 11 includes a torsion spring 111 movably sleeved on the rotating shaft 12, a connecting rope 112 fixedly connected to the side of the opening and closing plate 10 away from the opening 9, and a transmission member 113 arranged on the protective cover 8. The torsion spring 111 is used to drive the opening and closing plate 10 to rotate towards the direction close to the opening 9. One end of the torsion spring 111 is fixedly arranged on the opening and closing plate 10, and the other end is fixedly arranged on the protective cover 8. The connecting rope 112 is located on the side of the opening and closing plate 10 close to the rotating shaft 12. A guiding ring 13 is fixedly connected to the side of the protective cover 8 away from the opening 9. The connecting ropes 112 correspond to the guiding blocks 4 one by one, and the guiding rings 13 correspond to the connecting ropes 112 one by one. The connecting ropes 112 slide through the corresponding guiding rings 13 and the protective cover 8 and extend into the protective cover 8. The transmission member 113 is used to pull or release the corresponding connecting ropes 112 when the guiding blocks 4 slide. When the guiding blocks 4 slide away from the rotating rod 2, the transmission member 113 pulls the corresponding connecting ropes 112.

[0049] Refer to Figure 2 , Figure 3 and Figure 4 , the transmission member 113 includes a slider 1131 sliding in the protective cover 8, a first magnet 1132 fixed to the side of the slider 1131 close to the opening 9, a first iron sheet 1133 fixed to the side of the guiding block 4 close to the rotating rod 2, a second iron sheet 1134 fixed to the side of the slider 1131 close to the opening 9, and a second magnet 1135 fixed to the side wall of the protective cover 8. The sliders 1131 correspond to the guiding blocks 4 one by one. The sliding direction of the slider 1131 is parallel to the sliding direction of the guiding block 4. The slider 1131 is located on the side of the corresponding guiding block 4 close to the rotating rod 2. The longitudinal section of the slider 1131 is T-shaped. A connecting groove 24 slidably matched with the slider 1131 is formed on the roof plate 1; one end of the connecting rope 112 located in the protective cover 8 is fixedly arranged on the corresponding slider 1131. The first iron sheet 1133 is used for adsorbing and cooperating with the first magnet 1132. The adsorption force between the first iron sheet 1133 and the first magnet 1132 is greater than the torsion force of the torsion spring 111. The second magnet 1135 is located on the side of the slider 1131 close to the opening 9. The second magnet 1135 is used for adsorbing and cooperating with the second iron sheet 1134. The adsorption force between the second iron sheet 1134 and the second magnet 1135 is greater than the torsion force of the torsion spring 111. A water-absorbing cloth 25 is bonded to the side of the opening and closing plate 10 close to the opening 9. When the second magnet 1135 and the second iron sheet 1134 are adsorbed and cooperated, the water-absorbing cloth 25 is located above the opening and closing plate 10.

[0050] When the guide block 4 moves away from the rotating rod 2, the adsorption between the first magnet 1132 and the first iron sheet 1133 drives the slider 1131 to slide towards the second magnet 1135, causing the slider 1131 to pull the connecting rope 112, and the opening and closing plate 10 rotates away from the opening 9, opening the opening 9 until the second iron sheet 1134 on the slider 1131 moves to adsorb with the second magnet 1135. At this time, the side of the opening and closing plate 10 away from the opening 9 approaches the top wall of the protective cover 8, and the second magnet 1135 blocks the sliding of the slider 1131. As the guide block 4 continues to move out of the protective cover 8, the first magnet 1132 and the first iron sheet 1133 are separated, and the adsorption force between the second magnet 1135 and the second iron sheet 1134 maintains the position of the slider 1131, thereby maintaining the position of the opening and closing plate 10, so that rainwater falls on the water absorption cloth 25 and is not likely to strike the top wall of the protective cover 8.

[0051] When the guide block 4 slides towards the rotating rod 2, the guide block 4 gradually approaches the slider 1131, causing the first magnet 1132 and the first iron sheet 1133 to adsorb, and then pushing the slider 1131 to slide away from the second magnet 1135, which helps to reduce the pulling force of the connecting rope 112 on the opening and closing plate 10. Under the action of the torsion spring 111, the opening and closing plate 10 rotates towards the opening 9 to gradually block the opening 9 and protect the flexible cloth 3.

[0052] Refer to Figure 1 and Figure 2 , a lapping plate 26 is fixed between the protective covers 8 on both sides. A notch (not shown in the figure) for the connecting rope 112 to pass through is provided on the lapping plate 26. The setting of the lapping plate 26 makes it difficult for rainwater to accumulate between the protective covers 8 on both sides.

[0053] The implementation principle of the embodiment of this application is as follows: When it rains, the rainwater falling on the roof slab 1 flows into the water receiving groove 6 and gathers, and then flows into the water collecting cylinder 533 from both ends of the water receiving groove 6. The water level in the water collecting cylinder 533 rises rapidly, and the rainwater drives the floating plate 534 and the counterweight 21 to move upward in the direction close to the winding drum 531, so that the rack 535 gradually meshes with the corresponding gear 532. The gear 532 drives the winding drum 531 to rotate, and the winding drum 531 winds up the pull rope 52. The pull rope 52 drives the corresponding guide block 4 to slide away from the rotating rod 2 through the guide pulley 51. The adsorption between the first magnet 1132 and the first iron sheet 1133 drives the slider 1131 to slide in the direction close to the second magnet 1135, so that the slider 1131 pulls the connecting rope 112, and the connecting rope 112 pulls the opening and closing plate 10 to rotate away from the opening 9, opening the opening 9 until the second iron sheet 1134 on the slider 1131 moves to adsorb with the second magnet 1135. The side of the opening and closing plate 10 away from the opening 9 is close to the top wall of the protective cover 8. As the guide block 4 continues to move, the flexible cloth 3 is pulled out of the protective cover 8 and gradually covers the roof slab 1. The first magnet 1132 and the first iron sheet 1133 are separated, and the adsorption force between the second magnet 1135 and the second iron sheet 1134 maintains the position of the opening and closing plate 10, so that the rainwater falls on the water absorption cloth 25; until the flexible cloth 3 completely covers the roof slab 1 and the counterweight 21 slides to the top of the groove 22. At this time, the excess water in the water collecting cylinder 533 flows out through the water outlet hole 23, and the falling rainwater hits the flexible cloth 3, which can reduce the noise generated by the rain hitting and is not likely to affect people's rest.

[0054] When the rain stops, the rainwater in the water collecting cylinder 533 gradually flows out through the through hole 7, and the water level drops. The floating plate 534 moves downward under the gravity of the counterweight 21. The rack 535 drives the gear 532 and the winding drum 531 to rotate to unwind the pull rope 52, reducing the pulling force on the guide block 4. At this time, under the action of the torsion spring 14, the rotating rod 2 is driven to rotate to wind up the flexible cloth 3. The flexible cloth 3 drives the guide block 4 to slide in the direction close to the rotating rod 2. The guide block 4 gradually approaches the slider 1131 and enters the protective cover 8, so that the first magnet 1132 and the first iron sheet 1133 are adsorbed. Then, the slider 1131 is pushed to slide away from the second magnet 1135, reducing the pulling force of the connecting rope 112 on the opening and closing plate 10. Under the action of the torsion spring 111, the opening and closing plate 10 rotates in the direction close to the opening 9, so as to gradually block the opening 9, which helps to store and protect the flexible cloth 3.
