Description

Technical Field

[0001] This utility model relates to the field of building component technology, and in particular to an automatically adjustable square overflow outlet device for building roofs. Background Technology

[0002] Roof overflow systems should have two functions: discharging rainwater exceeding the design recurrence interval and providing emergency backup drainage in case of blockage in the rainwater drainage network. The installation of roof overflow systems is related to the structural safety of the roof, especially given the increasing frequency of extreme weather events globally and the frequent occurrence of roof collapses due to heavy rain. Overflow systems should consider the safety and reliability of the building throughout its entire life cycle, taking into account both normal and emergency uncertainties.

[0003] The placement of overflow outlets is crucial to both the structural safety and aesthetics of the roof. Determining the appropriate height and dimensions is challenging; placing them too low can lead to frequent overflows that negatively impact the building facade, while placing them too high may prevent timely drainage and compromise the roof's structural integrity. Therefore, the height of the overflow outlet is critical and should be determined based on the specific circumstances of each project. Currently, calculations primarily rely on formulas, but the accuracy of formulas used in different standards is somewhat controversial. Furthermore, daily use involves considering numerous parameters, making calculations complex and prone to errors.

[0004] A node structure for a rainwater overflow outlet on a building roof is disclosed in Chinese patent document CN214402477U. This node structure includes a roof body, an eaves fixed to one side of the roof body, a curtain wall vertically fixed to the roof body, multiple auxiliary overflow holes on the eaves, multiple main overflow holes reserved between the curtain wall and the roof body, a drain pipe installed in each main overflow hole, a sealant layer between the drain pipe and the curtain wall, a sealant paste layer between the drain pipe and the roof body, and a polyurethane waterproof layer arranged on the inner side of the drain pipe's inlet. Based on rainwater hopper data, this invention uses the bottom elevation of the overflow outlet to control the water depth in front of the hopper, avoiding pressure flow in the rainwater downpipe and preventing overflowing rainwater from being thrown into the air, thus reducing the impact on the surrounding area. The overflow outlet of this invention can effectively and promptly drain accumulated water from the roof, has a simple structure, good sealing performance, and extends the roof's service life. However, the node structure of this building roof rainwater overflow outlet is not convenient for automatic adjustment and relocation.

[0005] To address the shortcomings of the existing technology, providing an automatically adjustable square overflow outlet device for building roofs is a problem worthy of research. Utility Model Content

[0006] The purpose of this invention is to overcome the disadvantage that the height of the overflow outlet is inconvenient to adjust, and to provide an automatically adjustable square overflow outlet device for building roofs, which achieves the technical effect of adjusting the overflow outlet according to the specific construction conditions.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An automatically adjustable square overflow outlet device for building roof includes an overflow outlet installed on the building roof, lifting mechanisms installed at the four corners of the overflow outlet, a lifting seat slidably connected to the overflow outlet via the lifting mechanisms, water inlets opened on the four sides of the bottom of the lifting seat, and buoyancy mechanisms installed at the four corners of the lifting seat.

[0009] The bottom of the overflow outlet is connected to a dedicated backup drainage system.

[0010] The outer shape of the overflow port is adapted to the inner shape of the lifting seat. The top of the lifting seat is frustum-shaped. The water inlet and the top opening of the overflow port are connected, which can enable rapid drainage of extreme rainfall. By defining the shape of the overflow port and the lifting seat, there is no gap between them, which prevents rainfall from entering the overflow port through the gap between them.

[0011] The lifting mechanism includes sliding rods fixedly connected to the four corners of the overflow port, and sliding grooves opened at the four corners of the lifting seat.

[0012] The sliding rod is adapted to the shape of the sliding groove, and the sliding rod passes through the sliding groove. The lifting seat is slidably connected to the overflow port through the cooperation of the sliding rod and the sliding groove. By setting a lifting mechanism composed of the sliding rod and the sliding groove between the overflow port and the lifting seat, the lifting seat can be raised and lowered above the overflow port to complete the opening and closing adjustment.

[0013] The buoyancy mechanism includes several threaded holes at the four corners of the lifting seat, and buoyancy balls threaded onto the threaded holes.

[0014] The threaded holes are vertically and equidistantly distributed at the four corners of the lifting seat. The buoyancy of the four buoyant balls in the water is greater than the total weight of the lifting seat. By setting buoyant balls at the four corners of the lifting seat, when the water level on the roof of the building is higher than the warning value, buoyancy is generated on the lifting seat with buoyant balls, causing the lifting seat to rise. Then the water inlet and the overflow outlet are connected, and the accumulated water enters the overflow outlet from the water inlet to complete the drainage.

[0015] The lifting seat has slots on all four sides, which are located above the water inlet. By setting slots on the four sides of the lifting seat, decorative panels can be installed in the slots to decorate the lifting seat, so that the overflow outlet can be used as a decorative means to enhance the building facade when it is closed.

[0016] Positive and beneficial effects:

[0017] 1. This automatically adjustable square overflow outlet device for building roofs allows for adjustment of the height of the buoyancy ball on the lifting base by setting threaded holes of different heights. Adjusting the height of the buoyancy ball allows for different water levels required to connect the inlet and the overflow outlet. The higher the buoyancy ball, the higher the water level required for drainage when connecting the inlet and the overflow outlet, thus enabling rapid adjustment of the overflow outlet's drainage level. This allows the overflow outlet device to adjust the overflow water level according to the building's needs.

[0018] 2. This automatically adjustable square overflow outlet device for building roofs has a slidingly connected lifting seat on the outside of the overflow outlet. When the lifting seat is lowered, it closes the top opening of the overflow outlet, and the overflow outlet is in a closed state. When it is necessary to drain extreme rainfall, the lifting seat is raised under the action of the buoyancy mechanism, and the water inlet is connected to the top opening of the overflow outlet, so that the extreme rainfall can be drained quickly.

[0019] 3. The automatically adjustable square overflow outlet device for building roofs can be decorated with decorative panels by setting slots on the four sides of the lifting seat, so that the overflow outlet can be used as a decorative means to enhance the building facade when closed.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0030] like Figures 1 to 8 As shown, an automatically adjustable square overflow outlet device for building roof includes an overflow outlet 1 installed on the building roof, a lifting mechanism 2 installed at the four corners of the overflow outlet 1, a lifting seat 3 slidably connected to the overflow outlet 1 via the lifting mechanism 2, water inlets 4 opened on the four sides of the bottom of the lifting seat 3, and a buoyancy mechanism 5 installed at the four corners of the lifting seat 3.

[0031] The bottom of overflow outlet 1 is connected to a dedicated backup drainage system.

[0032] like Figures 1 to 3 As shown, the outer shape of the overflow port 1 is adapted to the inner shape of the lifting seat 3. The top of the lifting seat 3 is frustum-shaped. By setting the lifting seat 3 in a sliding connection on the outside of the overflow port 1, when the lifting seat 3 falls, it closes the top opening of the overflow port 1, and the overflow port is in a closed state. When it is necessary to drain extreme rainfall, the lifting seat 3 is raised under the action of the buoyancy mechanism 5, and the water inlet 4 is connected to the top opening of the overflow port 1, so that the extreme rainfall can be drained quickly. By limiting the shape of the overflow port 1 and the lifting seat 3, there is no gap between the two, and the situation of rainfall entering the overflow port 1 through the gap between the two is avoided.

[0033] Furthermore, setting the top of the lifting seat 3 to a frustum shape can prevent dust and other debris from accumulating on the lifting seat 3, which would increase the weight of the lifting seat 3 and prevent it from being lifted by the buoyancy mechanism 5. Example 2

[0034] like Figures 5 to 8 As shown, the lifting mechanism 2 includes sliding rods 201 fixedly connected to the four corners of the overflow port 1, and sliding grooves 202 opened at the four corners of the lifting base 3.

[0035] like Figures 5 to 8As shown, the sliding rod 201 and the sliding groove 202 are adapted to each other in shape. The sliding rod 201 passes through the sliding groove 202. The lifting seat 3 is slidably connected to the overflow port 1 through the cooperation of the sliding rod 201 and the sliding groove 202. By setting the lifting mechanism 2 composed of the sliding rod 201 and the sliding groove 202 between the overflow port 1 and the lifting seat 3, the lifting seat 3 can be raised and lowered above the overflow port 1 to complete the opening and closing adjustment. Example 3

[0036] like Figures 6 to 8 As shown, the buoyancy mechanism 5 includes several threaded holes 501 opened at the four corners of the lifting seat 3, and buoyancy balls 502 threadedly connected to the threaded holes 501.

[0037] like Figures 6 to 8 As shown, threaded holes 501 are vertically and equidistantly distributed at the four corners of the lifting seat 3. The buoyancy of the four buoyant balls 502 in the water is greater than the total weight of the lifting seat 3. By setting buoyant balls 502 at the four corners of the lifting seat 3, when the water level on the roof of the building is higher than the warning value, buoyancy is generated on the lifting seat 3 with buoyant balls 502, causing the lifting seat 3 to rise. Then the water inlet 4 is connected to the overflow outlet 1, and the accumulated water enters the overflow outlet 1 from the water inlet 4 to complete the drainage.

[0038] By setting threaded holes 501 of different heights on the lifting base 3, the height of the buoyancy ball 502 on the lifting base 3 can be adjusted. Adjusting the height of the buoyancy ball 502 can make the water level required to connect the inlet 4 and the overflow 1 different. The higher the height of the buoyancy ball 502, the higher the water level required for the inlet 4 and the overflow 1 to connect for drainage. This enables rapid adjustment of the drainage water level of the overflow outlet, allowing the overflow outlet device to adjust the overflow water level according to the building's needs. Example 4

[0039] like Figures 3 to 6 As shown, slots 6 are provided on all four sides of the lifting seat 3. The slots 6 are located above the water inlet 4. By setting slots 6 on the four sides of the lifting seat 3, decorative panels can be installed in the slots 6 to decorate the lifting seat 3. This allows the overflow outlet to serve as a decorative means to enhance the building facade when it is closed.

[0040] The working principle of this utility model is as follows:

[0041] S1. A sliding connection lifting seat 3 is provided on the outside of the overflow port 3. When the lifting seat 3 is lowered, it closes the top opening of the overflow port 1, and the overflow port is in a closed state. When it is necessary to drain extreme rainfall, the lifting seat 3 is raised under the action of the buoyancy mechanism 5, and the water inlet 4 is connected to the top opening of the overflow port 1.

[0042] S2. Threaded holes 501 of different heights are set on the lifting seat 3 so that the height of the buoyancy ball 502 on the lifting seat 3 can be adjusted. Adjusting the height of the buoyancy ball 502 can make the water level required to connect the inlet 4 and the overflow 1 different. The higher the height of the buoyancy ball 502, the higher the water level required to connect the inlet 4 and the overflow 1 for drainage, thereby realizing the rapid adjustment of the drainage water level of the overflow.

[0043] S3. Slots 6 are provided on the four sides of the lifting seat 3. Decorative panels can be installed in the slots 6 to decorate the lifting seat 3, so that the overflow port can be used as a decorative means to enhance the building facade when it is closed.

[0044] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
