Description

Technical Field

[0001] The utility model relates to the technical field of pergolas, and particularly relates to a drainage device and a pergola equipped with the drainage device. Background Art

[0002] In the fields of building structures and outdoor pergolas, the importance of drainage devices is self-evident. With the increasing diversification of building designs, the application of outdoor pergola structures is becoming more and more extensive. However, these pergola structures usually have a large canopy area and irregular shapes, which pose great challenges to drainage.

[0003] Existing drainage devices often have the following limitations: it is difficult to control the water accumulation area. Due to the irregular shape of the canopy, water is likely to accumulate in certain areas, and existing drainage devices are difficult to effectively guide this accumulated water to the drain outlet, resulting in difficulty in effectively controlling the water accumulation area and increasing the risk of structural damage. The drainage efficiency is low. The design of some drainage devices is unreasonable, the drainage channels are narrow or there is a risk of blockage, resulting in low drainage efficiency. During heavy rainfall, the accumulated water that cannot be drained in time will exert pressure on the canopy structure and even cause problems such as leakage. Maintenance is inconvenient. During the use of some drainage devices, the maintenance difficulty is relatively large. For example, some components are difficult to disassemble and clean, and are prone to accumulating dirt and debris, further affecting the drainage effect. Moreover, when the device fails, the repair is also relatively difficult, requiring a lot of time and effort.

[0004] Therefore, in order to solve the problems such as difficult control of the water accumulation area, low drainage efficiency, and complex installation and maintenance existing in existing pergolas, it is urgently necessary to design a drainage device and a pergola equipped with the drainage device to solve the above technical problems. Summary of the Utility Model

[0005] In order to solve the problems such as difficult control of the water accumulation area, low drainage efficiency, and complex installation and maintenance existing in existing pergolas, the present application provides a drainage device and a pergola equipped with the drainage device.

[0006] On the one hand, the utility model proposes a drainage device, which includes a cover plate assembly, a drain hopper, a diversion pipe, and a support steel column assembly: the cover plate assembly is installed on the top surface of the drain hopper, and the diversion pipe is fixed to the bottom of the drain hopper; the drain hopper includes an integrally formed first connecting portion, a drainage portion, and a second connecting portion along the drainage direction. The lower edge of the cover plate assembly is fixedly connected to the inner side wall of the first connecting portion, and one end of the diversion pipe is fixedly connected to the second connecting portion; the top of the support steel column assembly is fixed to the outer side wall of the first connecting portion, and the other end of the diversion pipe discharges water through the first through hole of the support steel column assembly.

[0007] In some specific embodiments, the cover plate assembly includes an openable cover plate, ear buttons, and a threaded portion. A plurality of drain holes are provided on the inner surface of the openable cover plate. The ear buttons are circumferentially and spaced apart along the outer periphery of the openable cover plate. The threaded portion is provided at the lower edge of the openable cover plate for fixedly connecting to the first connecting portion.

[0008] In some specific embodiments, through holes for the positioning posts to pass through are provided on the ear buttons. With the through holes designed on the ear buttons, accurate positioning during installation can be ensured, thus avoiding water leakage problems caused by installation deviation. After the positioning posts pass through the through holes, the precise combination of the cover plate assembly and the water leakage hopper can be ensured, thereby enhancing the sealing performance and protection of the drainage device and improving the overall reliability.

[0009] In some specific embodiments, the cross-sectional diameter of the first connecting portion is greater than the cross-sectional diameters of the drainage portion and the second connecting portion.

[0010] In some specific embodiments, the minimum cross-sectional diameter of the drainage portion is greater than the cross-sectional diameter of the diversion pipe. With the design of different cross-sectional diameters, a smooth water flow guide can be formed inside the water leakage hopper, effectively preventing blockage or backflow of water during the drainage process, ensuring that the drainage portion can accommodate more water, while the diversion pipe can effectively accelerate the water flow speed to ensure a smooth drainage process.

[0011] In some specific embodiments, the support steel column assembly includes a central support steel pipe provided with a first through hole and a second through hole. The first through hole and the second through hole are respectively provided on the side wall and the bottom of the central support steel pipe.

[0012] In some specific embodiments, the support steel column assembly further includes a sealing plate, and the sealing plate is detachably installed with the second through hole. With the setting of the sealing plate, it is convenient to maintain or clean the drainage device when needed.

[0013] On the other hand, the present utility model proposes a pergola installed with a drainage device. The pergola includes a ceiling structure and columns. The ceiling structure is fixed on the upper part of the columns. The ceiling structure includes a membrane cloth and a concave steel frame structure. The membrane cloth is installed along the concave steel frame structure and is provided on the upper surface of the concave steel frame structure. The lowest point of the ceiling structure is provided with the above-mentioned drainage device, and the cover plate assembly is installed on the lowest point position of the concave steel frame structure through the membrane cloth. The concave steel frame structure optimizes the natural flow direction of rainwater, can minimize the retention time of rainwater on the ceiling to the greatest extent, and enhances the overall drainage efficiency.

[0014] In some specific embodiments, the ceiling structure further includes diagonal bracing steel pipes. One end of the diagonal bracing steel pipe is connected through the center bracing steel pipe of the support steel column assembly, and the other end of the diagonal bracing steel pipe is connected through the column. The diversion pipes are distributed along the diagonal bracing steel pipe and the cavity structure of the column for draining water. The design of the diagonal bracing steel pipe not only plays a role in structural support but also can serve as a drainage channel to introduce the diversion pipes into the column and then drain the water from the diversion pipes into the drainage system.

[0015] In some specific embodiments, the top plane of the pergola is in the shape of a water droplet.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. The setting of the diameters of each cross-section in the drainage device improves the treatment capacity during rainwater collection. The smallest diameter of the diversion pipe effectively increases the flow velocity of the water flow, ensuring that the water flow can be quickly discharged from the system.

[0018] 2. The detachable design of the sealing plate not only facilitates the daily maintenance of the system but also enables convenient maintenance when the drainage device becomes blocked or fails.

[0019] 3. The drainage device is installed at the lowest point of the membrane cloth, realizing the natural flow, collection, diversion, and discharge of rainwater from the ceiling structure, ensuring that rainwater can be quickly collected and discharged through the drainage device, and avoiding water accumulation problems. Through this systematic drainage device, the service life of the ceiling can be effectively extended, and structural deformation or damage caused by water accumulation can be avoided.

[0020] 4. The support steel column assembly cooperates with the concave steel frame in the pergola structure to provide a stable support for the membrane cloth and also provides a reasonable installation space for the drainage device, effectively solving the problem of water accumulation in outdoor pergolas, extending the service life of the pergola, and improving the stability of the overall structure.
