[0021] A wind-pressure resistant metal roof structure for a hydropower station powerhouse, such as Figures 1-3 As shown, the system includes a steel structure 1, on which a roof panel 101 is mounted. It also includes a first support mechanism, which comprises two sets of U-shaped frames A201 slidably mounted within the roof panel 101 in a front-to-back direction. Each set consists of two frames, located on the front and rear sides of the roof panel 101 respectively, and arranged opposite each other. Two sets of sliding grooves A are perforated in the roof panel 101, each set consisting of two grooves, arranged opposite each other. A component is elastically slidably mounted within the sliding grooves A and fixedly installed on the top of the U-shaped frames A201. The vertical plate A202, steel structure 1 has two sets of purlin frames A203 fixedly installed inside, each set consisting of two, and arranged opposite each other on the left and right. The purlin frame A203 is located on the lower side of the corresponding U-shaped frame A201. A turntable A204 is rotatably installed inside the purlin frame A203. A support bar A205 is hinged to the turntable A204. A support bar B206 is hinged to the support bar A205. A turntable B207 is hinged to the support bar B206. A switching mechanism for changing the direction of the support bar A205 and the support bar B206 is installed inside the purlin frame A203.

[0022] like Figures 3-6As shown, the first supporting mechanism further comprises a sliding block A301 elastically slidingly installed in the purlin frame A203, the rotating disc B207 is rotatably installed at one side of the sliding block A301, the U-shaped frame A201 is fixedly provided with an extrusion plate A302 near the sliding block A301, the top of the sliding block A301 is fixedly provided with a convex shaft A, one side of the extrusion plate A302 is provided with a groove A matched with the convex shaft A, the extrusion plate A302 can move the sliding block A301 by matching with the convex shaft A when moving, and the first limiting assembly is installed on the U-shaped frame A201.

[0023] As shown in Figure 5 With Figure 6 As shown, the first limiting assembly comprises a pair of elastic telescopic rods A401 installed on the inner wall of the U-shaped frame A201, the telescopic end of the elastic telescopic rod A401 is fixedly provided with a limiting block A402, the limiting block A402 is slidingly installed on the purlin frame A203, a pair of clamping grooves A matched with the limiting block A402 are provided on the front and rear sides of the sliding block A301, and the limiting block A402 can limit the sliding block A301 when clamped into the clamping groove A.

[0024] As shown in Figure 7 With Figure 8 As shown, the switching mechanism comprises an adjusting plate 501 slidingly installed on the U-shaped frame A201 in the front-rear direction, the U-shaped frame A201 is provided with a through groove located below the adjusting plate 501, the adjusting plate 501 is fixedly provided with an L-shaped rod located in the through groove, the bottom of the L-shaped rod is fixedly provided with a driving rack 502, the driving rack 502 is elastically slidingly installed in the purlin frame A203 in the front-rear direction, the elastic force of the driving rack 502 is smaller than that of the vertical plate A202, the purlin frame A203 is rotatably installed with a driving gear 503 engaged with the driving rack 502, the wheel shaft of the driving gear 503 is fixedly connected with the rotating disc A204, and the adjusting plate 501 can rotate the rotating disc A204 when moving.

[0025] At the beginning, the strut A205 and the strut B206 are all retracted in the corresponding purlin frame A203, the strut A205, the strut B206 and the purlin frame A203 form an upward triangle structure, so as to reduce the volume for installation when building a factory building, when the strong wind flows from front to back, because the elastic force of the driving rack 502 is smaller than the elastic force of the vertical plate A202, when the two adjusting plates 501 on the front side are impacted by the strong wind, the driving rack 502 corresponding to the adjusting plate 501 abuts against the inner wall of the purlin frame A203, the driving rack 502 keeps the two adjusting plates 501 on the front side stable through the L-shaped rod, the two adjusting plates 501 on the back side are blown by the strong wind and slide backward along the corresponding U-shaped frame A201, the adjusting plate 501 drives the corresponding L-shaped rod to slide backward along the through slot of the U-shaped frame A201, the L-shaped rod drives the corresponding driving rack 502 to slide and elastically retract along the purlin frame A203, the driving rack 502 drives the driving gear 503 to rotate, the wheel shaft of the driving gear 503 drives the rotating disc A204 to rotate, the rotating disc A204 drives the rotating disc B207 to rotate one hundred and eighty degrees through the strut A205 and the strut B206, it needs to be explained that the internal space of the purlin frame A203 is enough for the strut A205 and the strut B206 to rotate, then the four vertical plates A202 are elastically extended and slide backward along the sliding slot A of the roof plate 101 under the action of the strong wind, and drive the U-shaped frame A201 to slide backward, the U-shaped frame A201 drives the extrusion plate A302 to move backward, and drives the limiting block A402 to move backward through the elastic expansion rod A401, the limiting block A402 extends into the purlin frame A203, the extrusion plate A302 extrudes the convex shaft A on the sliding block A301 through the groove A thereon, the convex shaft A is forced to drive the sliding block A301 to elastically retract and slide, the sliding block A301 drives the strut B206 to move through the rotating disc B207, the strut B206 drives the strut A205 to move, then the sliding block A301 contacts and extrudes the wedge surface of the limiting block A402, the limiting block A402 is forced to drive the elastic expansion rod A401 to elastically retract, until the limiting block A402 is aligned with the clamping groove A of the sliding block A301, the elastic expansion rod A401 elastically extends and drives the limiting block A402 to slide and clamp into the clamping groove A to limit the sliding block A301, the strut A205 and the strut B206 on the front side form a stable upward triangle structure with the purlin frame A203, thereby providing a force against the positive pressure for the two purlin frames A203 on the front side, preventing the two purlin frames A203 on the front side from being bent downward under the action of the positive pressure, at the same time, the strut A205 and the strut B206 on the back side form a stable downward triangle structure with the purlin frame A203, thereby providing a force against the negative pressure for the two purlin frames A203 on the back side, preventing the two purlin frames A203 on the back side from being bent upward under the action of the negative pressure.

[0026] When the strong wind flows from back to front, the two adjusting plates 501 on the back side are impacted by the strong wind, and the driving racks 502 corresponding thereto abut against the inner wall of the purlin frame A203. The driving racks 502 keep the two adjusting plates 501 on the back side stable through the L-shaped rods. The two adjusting plates 501 on the front side are blown by the strong wind and slide forward along the corresponding U-shaped frames A201. The adjusting plates 501 drive the corresponding L-shaped rods to slide forward along the through grooves of the U-shaped frames A201. The L-shaped rods drive the corresponding driving racks 502 to slide elastically and shrink along the purlin frames A203. The driving racks 502 drive the driving gears 503 to rotate. The wheel shafts of the driving gears 503 drive the rotating discs A204 to rotate. The rotating discs A204 drive the rotating disc B207 to rotate one hundred and eighty degrees through the struts A205 and the struts B206. Subsequently, the four vertical plates A202 are blown by the strong wind and elastically shrink and slide forward along the sliding grooves A of the roof plates 101, and drive the U-shaped frames A201 to slide forward. The U-shaped frames A201 drive the pressing plates A302 to move forward, and drive the limiting blocks A402 to move forward through the elastic extension rods A401. The limiting blocks A402 extend into the purlin frames A203. The pressing plates A302 extrude the convex shafts A on the sliding blocks A301 through the grooves A. The convex shafts A are driven to slide elastically and shrink. The sliding blocks A301 drive the struts B206 to move through the rotating disc B207. The struts B206 drive the struts A205 to move. Subsequently, the sliding blocks A301 contact and extrude the wedge surfaces of the limiting blocks A402. The limiting blocks A402 are driven to elastically shrink and extend the elastic extension rods A401 until the limiting blocks A402 are aligned with the clamping grooves A of the sliding blocks A301. The elastic extension rods A401 elastically extend and drive the limiting blocks A402 to slide and clamp into the clamping grooves A to limit the sliding blocks A301. The struts A205 and the struts B206 on the back side form an upward stable triangular structure with the purlin frames A203, thereby providing the two purlin frames A203 on the back side with a force resisting the positive pressure to prevent the two purlin frames A203 on the back side from bending downward under the action of the positive pressure. Meanwhile, the struts A205 and the struts B206 on the front side form a downward stable triangular structure with the purlin frames A203, thereby providing the two purlin frames A203 on the front side with a force resisting the negative pressure to prevent the two purlin frames A203 on the front side from bending downward under the action of the negative pressure.

[0027] As Figure 8 With Figure 9As shown, it also includes a second support mechanism, which includes two sets of U-shaped frames B601 that are slidably installed in the roof panel 101 in the front-back direction, with two in each set. The two sets of U-shaped frames B601 are located between the two sets of U-shaped frames A201 and are arranged opposite each other. Two sets of sliding grooves B are opened through the roof panel 101, with two in each set and arranged opposite each other. Vertical plates B602 that are fixedly installed on the U-shaped frames B601 are slidably installed in the sliding grooves B. Two sets of purlin frames B603 are fixedly installed in the steel structure 1, with two in each set and arranged opposite each other. The purlin frames B603 are located on the lower side of the corresponding U-shaped frames B601. A support bar C604 is hinged in the purlin frame B603, and a support bar D605 is hinged on the support bar C604.

[0028] like Figure 10 and Figure 11 As shown, the second support mechanism also includes a slider B701 that is elastically slidably installed in the purlin frame B603. The support bar D605 is hinged to the slider B701. An extrusion plate B702 is fixedly installed on the inner wall of the U-shaped frame B601 near the slider B701. A convex shaft B is fixedly installed at the bottom of the slider B701. A groove B that cooperates with the convex shaft B is opened on one side of the extrusion plate B702. When the extrusion plate B702 moves, it can make the slider B701 move by cooperating with the convex shaft B. A second limiting component is installed on the U-shaped frame B601.

[0029] like Figure 10 and Figure 11 As shown, the second limiting component includes a pair of elastic telescopic rods B801 installed on the inner wall of the U-shaped frame B601. A limiting block B802 is fixedly installed at the telescopic end of the elastic telescopic rod B801. The limiting block B802 is slidably installed on the purlin frame B603. A pair of slots B that cooperate with the limiting block B802 are provided on the front and rear sides of the slider B701. When the limiting block B802 is inserted into the slot B, it can limit the slider B701.

[0030] Initially, both support bars C604 and D605 retract into their corresponding purlin frames B603 to reduce volume and facilitate installation during factory construction. When strong winds flow from front to back or from back to front, the vertical plate B602 slides along the groove B of the roof panel 101 due to the impact of the strong winds, causing the U-shaped frame B601 to slide along the roof panel 101. The U-shaped frame B601 drives the pressing plate B702 to move, and through the elastic telescopic rod B801, it drives the limiting block B802 to move. The limiting block B802 extends into the purlin frame B603, and the pressing plate B702 presses against the convex shaft B on the slider B701 through its groove B. The convex shaft B, under force, causes the slider B701 to elastically contract. Sliding, slider B701 drives support bar D605 to move, support bar D605 drives support bar C604 to move, then slider B701 contacts and presses against the wedge-shaped surface of limiting block B802, limiting block B802 is forced to cause elastic telescopic rod B801 to elastically contract until limiting block B802 is aligned with the slot B of slider B701, elastic telescopic rod B801 elastically extends and drives limiting block B802 to slide into slot B to limit slider B701. Support bar C604, support bar D605 and purlin frame B603 form a downward stable triangular structure, which in turn provides purlin frame B603 with a force to resist negative pressure and prevent purlin frame B603 from bending upward under the action of negative pressure.

[0031] like Figure 12 and Figure 13 As shown, it also includes a reinforcing mechanism, which includes three sets of lifting rods 901 that slide vertically through and are installed on the roof panel 101. Each set consists of two rods, which are arranged opposite each other on the left and right. A swing plate 902 is hinged to the top of the lifting rod 901. A pull-down assembly 903 is connected to the lifting rod 901. The pull-down assembly 903 consists of a transmission rack, a transmission gear, and a swing arm. The transmission rack is fixedly installed at the bottom end of the lifting rod 901. The transmission gear is rotatably installed on the column of the factory structure (the column is existing technology and is not shown in the figure, so it will not be described here). The swing arm is fixedly installed at the end of the transmission gear and is hinged to the steel structure 1.

[0032] like Figure 12 and Figure 13 As shown, it also includes a horizontal plate 1001 fixedly installed on the top of the swing plate 902. When a strong wind impacts the horizontal plate 1001, the horizontal plate 1001 can drive the swing plate 902 to swing with the wind.

[0033] like Figure 13 As shown, it also includes a rectangular frame 1101 that is elastically slidably installed on the upper part of the outer wall of the lifting rod 901 in the horizontal direction. A pair of support rods 1102 that cooperate with the swing plate 902 are hinged inside the rectangular frame 1101. The support rods 1102 are used to provide support for the swing plate 902.

[0034] Initially, the swing plate 902 is in a horizontal state. When a strong wind flows from front to back, the horizontal plate 1001 is impacted by the strong wind, causing the swing plate 902 to rotate backward. The impact of the strong wind provides lift to the bottom of the swing plate 902. The swing plate 902, under this force, causes the lifting rod 901 to rise. The lifting rod 901 causes the transmission rack in the pull-down assembly 903 to rise. The transmission rack drives the transmission gear to rotate, and the transmission gear causes the swing arm to swing downward, so that the swing arm applies a downward pull force to the steel structure 1. The greater the lift provided by the strong wind to the swing plate 902, the greater the pull force of the swing arm on the steel structure 1. The greater the downward force applied by structure 1, the more the rectangular frame 1101 is blown by the strong wind and elastically contracts and slides backward along the outer wall of the lifting rod 901, driving the two support rods 1102 inside to move. The front support rod 1102 is squeezed upward by the outer wall of the lifting rod 901 and elastically contracts and rotates, while the rear support rod 1102 elastically releases and rotates downward. Subsequently, the front support rod 1102 contacts the bottom of the swing plate 902, providing support for the swing plate 902 and preventing the swing plate 902 from swinging arbitrarily when impacted by strong wind, which would prevent the swing plate 902 from receiving stable lift.

[0035] When a strong wind flows from back to front, the horizontal plate 1001 is impacted by the strong wind, causing the swing plate 902 to rotate forward. The strong wind impact provides lift to the bottom of the swing plate 902, which in turn causes the swing rod to exert a downward pull on the steel structure 1. At the same time, the rectangular frame 1101 is blown by the strong wind and extends forward elastically along the outer wall of the lifting rod 901, which drives the two support rods 1102 inside to move. The rear support rod 1102 is squeezed upward by the outer wall of the lifting rod 901 and rotates elastically, while the front support rod 1102 is released elastically and rotates downward. The rear support rod 1102 contacts the bottom of the swing plate 902, providing support for the swing plate 902 and preventing the swing plate 902 from swinging arbitrarily when impacted by the strong wind, which would cause the swing plate 902 to be unable to receive stable lift.

[0036] When the strong wind subsides, it no longer impacts the vertical plate A202 and the adjusting plate 501. The vertical plate A202 elastically releases or retracts to its sliding reset, driving the U-shaped frame A201 to move and reset. The U-shaped frame A201, through the elastic telescopic rod A401, drives the limiting block A402 to move and reset. The limiting block A402 disengages from the slot A of the slider A301, and the slider A301 releases its restraint and slides to its reset. It then drives the support bar B206 to move through the turntable B207. The support bar B206 drives... When support bar A205 moves, it retracts into the purlin frame A203 along with support bar B206. Subsequently, the rack 502 is elastically released and slides back to its original position, driving the L-shaped rod to move and the drive gear 503 to rotate. The L-shaped rod drives the adjusting plate 501 to move and reset, and the drive gear 503 drives the turntable A204 to rotate in reverse. The turntable A204, through support bars A205 and B206, drives the turntable B207 to rotate 180 degrees, thus resetting the first support mechanism.

[0037] Through the cooperation of the first support mechanism, the second support mechanism, and the reinforcing mechanism, a stable supporting force can be provided for the roof structure when strong winds pass over the factory roof, preventing damage to the roof structure.
