Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal roofing technology, and in particular to a leak-proof device for steel structure metal roofs. Background Technology
[0002] The roof is made of rigid metal and is the uppermost enclosure and load-bearing structure of the house. One of its main functions is to "protect from wind and rain". Roofs can be divided into flat roofs and pitched roofs according to the different drainage slopes. Generally, the slope of a flat roof is less than 10%, and the most commonly used slope is 2 to 3%, while the slope of a pitched roof is more than 10%.
[0003] Currently, traditionally, Chinese buildings use pitched roofs, including double-slope and four-slope roofs. These roofs have a relatively large slope, are flexible, drain quickly, and have good waterproofing. Since the 1960s, in order to reduce the self-weight of the roof, lower the project cost, and increase the degree of prefabrication and assembly of the roof, they have been generally replaced by reinforced concrete flat roofs. These roofs mostly use precast perforated roof panels and cast-in-place reinforced concrete roof panels. Flat roofs have lower costs, are easy to construct, have a simple structure, and a clean appearance. They are suitable for building plans of various shapes and sizes, and this type of roof is currently the most widely used.
[0004] However, most existing building roofs are flat structures. When it rains, the roof drainage is slow or incomplete, and water accumulation can cause leakage. In addition, the roof drainage pipes lack filtration mechanisms, and rainwater can wash away some debris, causing blockages in the roof drainage pipes and affecting roof drainage. Utility Model Content
[0005] To overcome the fact that most existing building roofs are flat structures, which cause slow or incomplete drainage during rainy days, resulting in water accumulation and leakage, and that roof drainage pipes lack filtration mechanisms, rainwater can wash away debris, leading to blockages in the roof drainage pipes and affecting roof drainage.
[0006] The technical solution of this utility model is as follows: a steel structure metal roof anti-leakage device, including a roof body, water outlet seats are provided on both sides of the bottom end of the roof body, water outlet is provided on the top surface of the water outlet seat, filter plate is fixedly connected to the inner side of the water outlet, water outlet pipe is provided below the water outlet at the bottom end of the water outlet seat, connecting frame is fixedly connected to the top end of the roof body, servo motor is fixedly connected to the top end of the connecting frame, transmission rod is fixedly connected to the bottom end of the servo motor at the inner side of the connecting frame, first lead screw is provided below the transmission rod at the inner wall of the connecting frame, displacement seats are movably connected to both ends of the first lead screw, and one end of the displacement seat extends to the top surface of the water outlet.
[0007] Preferably, the displacement seat is moved on the surface of the roof body and the filter plate by a servo motor in conjunction with a transmission rod and a first lead screw. A cleaning brush is provided at the bottom of the displacement seat. During the displacement process, the displacement seat cleans the surface of the roof body and the filter plate with the cleaning brush to prevent rainwater from remaining on the surface of the roof body and corroding the roof body, which could lead to leakage of the metal roof.
[0008] Preferably, the two sloping sides of the roof body are trapezoidal.
[0009] Preferably, bolts are provided at both ends of the bottom surface of the connecting frame, and the connecting frame is fixedly connected to the roof body by the bolts.
[0010] Preferably, the transmission rod is located at the output end of the servo motor at the bottom, and the transmission rod is connected to the servo motor via a coupling.
[0011] Preferably, bevel gears are provided at the intersection of the transmission rod and the first lead screw, and the transmission rod and the first lead screw are connected by bevel gear transmission.
[0012] Preferably, the first lead screw is a double-threaded lead screw, with the threads at both ends of the first lead screw being symmetrical about the first lead screw as the center, and the first lead screw meshing with the two displacement seats.
[0013] Preferably, a cleaning brush is provided at the bottom of the displacement seat. The cleaning brush is made of woven stainless steel wire and is in contact with the surface of the roof body and the filter plate.
[0014] The beneficial effects of this utility model are:
[0015] This steel structure metal roof waterproofing device uses a servo motor and a transmission rod to rotate the first lead screw. The first lead screw meshes with two displacement seats, causing the displacement seats to move on the surfaces of the roof body and the filter plate. The bottom of the displacement seat is equipped with a cleaning brush. During the displacement process, the displacement seat cleans the surfaces of the roof body and the filter plate with the cleaning brush, preventing rainwater from remaining on the surface of the roof body and corroding it, thus preventing the metal roof from leaking.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5 This utility model provides a technical solution: a steel structure metal roof anti-leakage device, including a roof body 1, with water outlet seats 9 on both sides of the bottom end of the roof body 1, a water outlet 5 on the top surface of the water outlet seat 9, a filter plate 6 fixedly connected to the inner side of the water outlet 5, a water outlet pipe 7 located below the water outlet 5 at the bottom end of the water outlet seat 9, a connecting frame 2 fixedly connected to the top end of the roof body 1, a servo motor 3 fixedly connected to the top end of the connecting frame 2, a transmission rod 10 fixedly connected to the bottom end of the servo motor 3 located inside the connecting frame 2, and a transmission rod 10 located below the connecting frame 10. The inner wall of component 2 is provided with a first lead screw 11, and both ends of the first lead screw 11 are movably connected to displacement seats 4. One end of the displacement seat 4 extends to the top surface of the outlet 5. Then, through the servo motor 3, in conjunction with the transmission rod 10 and the first lead screw 11, the displacement seat 4 is moved on the surface of the roof body 1 and the filter plate 6. The bottom end of the displacement seat 4 is provided with a cleaning brush 13. During the displacement process, the displacement seat 4 cleans the surface of the roof body 1 and the filter plate 6 through the cleaning brush 13 to prevent rainwater from remaining on the surface of the roof body 1 and corroding the roof body 1, which would lead to leakage of the metal roof.
[0024] Please see Figures 2-3 In this embodiment, the roof body 1 has two sloping sides and is trapezoidal. Bolts are provided at both ends of the bottom surface of the connecting frame 2. The connecting frame 2 is fixedly connected to the roof body 1 by bolts, which facilitates the connection between the connecting frame 2 and the roof body 1.
[0025] Please see Figures 4-5The transmission rod 10 is located at the output end of the servo motor 3. The transmission rod 10 and the servo motor 3 are connected by a coupling. A bevel gear 12 is provided at the intersection of the transmission rod 10 and the first lead screw 11. The transmission rod 10 and the first lead screw 11 are connected by the bevel gear 12. The first lead screw 11 is a double-threaded lead screw. The threads at both ends of the first lead screw 11 are symmetrical about the first lead screw 11. The first lead screw 11 meshes with the two displacement seats 4. A cleaning brush 13 is provided at the bottom of the displacement seat 4. The cleaning brush 13 is woven from stainless steel wire. The cleaning brush 13 is in contact with the surface of the roof body 1 and the filter plate 6, and then the roof body 1 and the filter plate 6 are cleaned by the cleaning brush 13.
[0026] When it rains during operation, rainwater flows through the sloping surfaces on both sides of the roof body 1 and is fed into the inside of the outlet 5, where it is then discharged. The servo motor 3, in conjunction with the transmission rod 10, causes the first lead screw 11 to rotate. The first lead screw 11 meshes with the two displacement seats 4, thereby causing the displacement seats 4 to move on the surfaces of the roof body 1 and the filter plate 6. A cleaning brush 13 is provided at the bottom of the displacement seat 4. During the displacement process, the displacement seat 4 cleans the surfaces of the roof body 1 and the filter plate 6 with the cleaning brush 13 to prevent rainwater from remaining on the surface of the roof body 1 and corroding it, which could lead to leaks in the metal roof.
[0027] Through the above steps, the servo motor 3, in conjunction with the transmission rod 10 and the first lead screw 11, causes the displacement seat 4 to move on the surfaces of the roof body 1 and the filter plate 6. A cleaning brush 13 is provided at the bottom of the displacement seat 4. During the displacement process, the displacement seat 4 cleans the surfaces of the roof body 1 and the filter plate 6 through the cleaning brush 13, preventing rainwater from remaining on the surface of the roof body 1 and corroding it, thus preventing leakage of the metal roof. This solves the problem that most existing building roofs are planar structures, and leakage occurs when the roof drainage is slow or incomplete during rainy weather, resulting in water accumulation. In addition, the roof drainage pipes lack a filtration mechanism, and rainwater washes away some debris, causing blockage of the roof drainage pipes and affecting roof drainage.
