[0032] The angle adjusting mechanism is used for controlling the synchronous overturning of the pair of inclined baffles 13 upward or downward, so as to adjust the inclination angle of the slope structure through the overturning of the pair of inclined baffles 13. When the inclined baffles 13 are overturned, the inclined baffles 13 and the extension plates 12 are relatively rotated through the rotating shaft hinge, so that the extension plates 12 can keep the horizontal state and adapt to the angle change of the inclined baffles 13 through the horizontal movement.

[0033] After the angle adjustment of the inclined baffles 13 is completed, the blanking plate 24 is installed at the lower end edge of the inclined baffles 13, and the blanking plate 24 is kept in the horizontal state, so as to facilitate the receiving of the falling objects and rainwater.

[0035] Please refer to the accompanying drawings Figure 3 and the accompanying drawings Figure 4 The angle adjusting mechanism comprises a rotating shaft 17, a control rotating rod 18, a driven gear 21, a driving gear 22, a servo motor 23 and a buffer inclined baffle. The upper ends of the pair of inclined baffles 13 are respectively embedded with the rotating shaft 17, and the driven gear 21 is coaxially and fixedly connected on the rotating shaft 17. The buffer inclined baffle is arranged above the pair of inclined baffles 13, the control rotating rod 18 is installed at the bottom of the buffer inclined baffle, the driving gear 22 is coaxially and fixedly connected on the control rotating rod 18 and is in meshing transmission connection between the pair of driven gears 21. The servo motor 23 is installed on the buffer inclined baffle through a motor protection box, and the output shaft of the servo motor 23 is coaxially and fixedly connected with the control rotating rod 18.

[0036] Preferably, the length of the rotating shaft 17 is slightly smaller than the length of the inclined baffle 13, and a notch is arranged in the upper end of the inclined baffle 13 for embedding the rotating shaft 17, and the driven gear 21 can be arranged in the middle of the rotating shaft 17. The length of the control rotating rod 18 can be consistent with the length of the rotating shaft 17, and the driving gear 22 can be arranged in the middle of the control rotating rod 18, and a pair of driven gears 21 are symmetrically arranged on both sides of the driving gear 22, so that the rotation of the driving gear 22 synchronously drives the rotation of the pair of driven gears 21, and the pair of driven gears 21 drives the pair of inclined baffles 13 to synchronously turn upward or downward around the rotating shaft 17.

[0037] The servo motor 23 can be installed on the buffer inclined baffle and beside the end of the control rotating rod 18 through the motor protection box, and the servo motor 23 drives the control rotating rod 18 to synchronously rotate through the output shaft. Preferably, the servo motor 23 can adopt the bidirectional rotating motor of the prior art, so that the control rotating rod 18 drives the driving gear 22 to rotate forward or reversely, thereby realizing the upward or downward turning function of the pair of inclined baffles 13.

[0038] Please refer to the accompanying drawings Figure 2 and the accompanying drawings Figure 3 , the buffer inclined baffle comprises a fixed inclined plate 14, a contraction inclined plate 15, a damping spring 16, a connecting rod 19 and a fixed block 20; the lower ends of the pair of fixed inclined plates 14 are respectively rotatably connected with the lower ends of the pair of inclined baffles 13 through rotating shaft hinges, the lower ends of the pair of contraction inclined plates 15 are respectively movably inserted into the upper ends of the pair of fixed inclined plates 14, and the upper ends of the pair of contraction inclined plates 15 are respectively rotatably connected with the two side ends of the fixed block 20 through rotating shaft hinges; the upper end of the connecting rod 19 is vertically fixedly connected with the bottom of the fixed block 20, and the lower end of the connecting rod 19 is movably sleeved with the control rotating rod 18 through a sleeve; and the damping springs 16 are respectively and intervally arranged between the fixed inclined plate 14 and the inclined baffle 13 and between the contraction inclined plate 15 and the inclined baffle 13.

[0039] Preferably, the fixed inclined plate 14 and the contraction inclined plate 15 can be made of light and high-strength plate members such as aluminum alloy plates, which are used for shielding sunlight, rain and falling objects and are not easy to be deformed and damaged. The fixed inclined plate 14 and the contraction inclined plate 15 are connected in a plug-in manner and arranged above the inclined baffle 13 through the damping springs 16, when the falling objects impact the fixed inclined plate 14 and the contraction inclined plate 15, the fixed inclined plate 14 and the contraction inclined plate 15 buffer the impact force in a relative expansion and contraction manner, and the elastic force generated by the compression of the damping springs 16 is further used to buffer the impact force, thereby reducing the damage rate of the buffer inclined baffle. The number, elastic coefficient, arrangement interval and position of the damping springs 16 can be adaptively adjusted according to the actual buffering requirements.

[0040] The connecting rod 19 is sleeved on the control rotating rod 18 through a sleeve, preferably, rotating bearings are arranged in the sleeve to facilitate the rotation of the control rotating rod 18 in the sleeve without affecting the stability of the connecting rod 19 and the fixing block 20.

[0041] Please refer to the accompanying Figure 1 to the accompanying Figure 4 The use method and working principle of the utility model are as follows:

[0042] The protective roof is stably arranged on the ground through the six supporting legs 2 at the bottom of the bottom plate 1, so that the pair of inclined baffles 13 are covered above the construction area. The height of the supporting legs 2 can be adaptively adjusted according to actual use requirements, so that the rest plate 3 on the bottom plate 1 can be used for the construction personnel to sit and rest.

[0043] The height of the pair of inclined baffles 3 can be adjusted according to the construction height requirement, so as to adjust the construction height below the roof and the sun-shading and ventilation effect of the roof. Specifically, the rocker 6 is manually rotated, so that the rocker 6 drives the first bevel gear 7 to synchronously rotate, the first bevel gear 7 meshes and drives the second bevel gear 9 to synchronously rotate, and the second bevel gear 9 drives the transmission rod 8 and the threaded rod 10 to synchronously rotate. Since the pair of lifting rods 5 are connected to the two ends of the fixed plate 11 and cannot rotate, the rotation of the threaded rod 10 is converted into the linear motion of the lifting rod 5 along the axial direction of the threaded rod 10 under the threaded transmission, so as to realize the ascending or descending motion of the lifting rod 5 relative to the fixed rod 4, and further realize the height adjustment of the pair of inclined baffles 13.

[0044] The inclination angle of the pair of inclined baffles 3 can be adjusted according to the construction use requirement, so as to adjust the construction height below the roof and the sun-shading and ventilation effect of the roof. Specifically, the servo motor 23 is started, the servo motor 23 drives the control rotating rod 18 to rotate, the control rotating rod 18 drives the driving gear 22 to synchronously rotate and meshes and drives a pair of driven gears 21 on the two sides, the driven gears 21 drive the inclined baffles 13 to rotate upward or downward through the rotating shaft 17 as the axial direction, and the inclined baffles 13 rotate through the rotating shaft hinge relative to the extension plate 12, so that the extension plate 12 only does small amplitude expansion and contraction motion relative to the fixed plate 11 in the horizontal direction, so as to adapt to the angle change of the inclined baffles 13.

[0045] The pair of inclined baffles 12 synchronously rotate through the pair of driven gears 21, so that the pair of extension plates 12 synchronously expand and contract relative to the fixed plate 11. After the inclined baffles 13 are rotated to the position, the pair of extension plates 12 and the fixed plate 11 can be locked and fixed through a plurality of bolts and nuts, so that the pair of inclined baffles 13, the pair of extension plates 12 and the fixed plate 11 form a roof structure of a stable isosceles triangle, and the buffer inclined baffles also form a roof structure of a stable isosceles triangle on the pair of inclined baffles 13, thereby constituting a roof of a double-layer slope structure.

[0046] When the inclined baffle 13 rotates upward, the damping spring 16 is compressed, the retractable inclined plate 15 extends into the fixed inclined plate 14, the fixed inclined plate 14 rotates relative to the inclined baffle 13 through the hinge shaft, and the retractable inclined plate 15 rotates relative to the fixed block 20 through the hinge shaft to adapt to the angle change of the inclined baffle 13. Similarly, when the inclined baffle 13 rotates downward, the damping spring 16 is stretched, the retractable inclined plate 15 extends out of the fixed inclined plate 14, the fixed inclined plate 14 rotates relative to the inclined baffle 13 through the hinge shaft, and the retractable inclined plate 15 rotates relative to the fixed block 20 through the hinge shaft to adapt to the angle change of the inclined baffle 13.

[0047] When the falling object falls on the fixed inclined plate 14 and the retractable inclined plate 15, the impact force causes the fixed inclined plate 14 and the retractable inclined plate 15 to retract relative to each other, the impact force causes the damping spring 16 to be compressed, and the elastic force of the damping spring 16 and the relative retraction of the fixed inclined plate 14 and the retractable inclined plate 15 form a buffer, effectively protecting the safety of the ceiling. At the same time, the falling object slides along the fixed inclined plate 14 and the retractable inclined plate 15 to the discharge plate 24, and the horizontally arranged discharge plate 24 and the protection plate 26 arranged at the edge thereof can effectively prevent the falling object from falling to the ground, thereby avoiding the situation that the falling object injures people.

[0048] When rain falls on the discharge plate 24, the fixed inclined plate 14 and the retractable inclined plate 15, it flows into the water tank 27 through the water outlet 25 on the discharge plate 24, facilitating the collection and reuse of rainwater.

[0049] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application, therefore, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
