Description

Technical Field

[0001] This application relates to the technical field of siphon drainage structures, and in particular to a siphon drainage structure for a double-layer structural slab roof. Background Art

[0002] The siphonic roof rainwater drainage system is a drainage system designed based on the siphon principle and natural gravity. Its core lies in achieving air-water separation through a specially designed rainwater hopper, so that the rainwater riser remains in a full-flow state; when the water in the riser reaches a certain capacity, a siphon effect will be generated, and then during the rainfall process, due to the continuous siphon effect, the entire system can quickly drain the rainwater on the roof.

[0003] During the use of the existing device, the roof may be exposed to wind and sun for a long time, making it easy for sundries to accumulate and dust to gather at the rainwater hopper. Moreover, these sundries and dust are likely to interfere with the drainage at the siphonic rainwater hopper during rainy weather, reducing the drainage efficiency. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, this application provides a siphon drainage structure for a double-layer structural slab roof, which overcomes the deficiencies of the prior art and aims to solve the problems that the roof is exposed to wind and sun for a long time, making it easy for sundries to accumulate and dust to gather at the rainwater hopper, and these sundries and dust are likely to interfere with the drainage at the siphonic rainwater hopper during rainy weather, reducing the drainage efficiency.

[0005] To achieve the above object, this application provides the following technical solution: A siphon drainage structure for a double-layer structural slab roof, including a wall, on one side of the wall, a plurality of first structural plates and second structural plates are installed. A plurality of the first structural plates are all located above the second structural plates, and a fixed beam is provided between them for connection. On one side of each of the plurality of first structural plates, a water guide groove is provided. Inside the water guide groove, a drainage box is installed. A first water inlet is provided around the drainage box, and the first water inlet corresponds to the sedimentation tank. Inside the drainage box, a water guide plate is provided. Below the water guide plate, a siphonic rainwater hopper is provided. Above the drainage box, a protective cover is installed. On one side of the protective cover, a mounting block is fixedly connected. Inside the protective cover, a drainage rack is provided. Above the drainage rack, a first limiting plate is provided. Above the four sides of the drainage rack, a third water inlet is provided, and the third water inlet is arranged corresponding to the water guide plate. Below the four sides of the drainage rack, a water outlet is provided. Inside the drainage rack, a fixing block is installed. Above the fixing block, a third limiting plate is provided. Inside the third limiting plate, an internal filter cylinder is fixedly connected. Below the internal filter cylinder, a filter port is provided. Below the siphonic rainwater hopper, a connecting pipe is installed. The other end of the connecting pipe is fixedly connected to a suspension pipe. One end of the suspension pipe is fixedly connected to a drain pipe.

[0006] By adopting the above technical solution, by setting a water guide groove, when it rains, the water flow will converge inside the water guide groove, and then enter the inside of the drainage box through the first water inlet. After flowing along the water guide plate to the third water inlet, it then enters the inside of the internal filter cylinder through the third water inlet, and reaches the space between the drainage rack and the internal filter cylinder from the filter port. By setting the filter port, the sundries inside the water can be filtered. Since the water will flow out from the water outlet to the inside of the siphonic rainwater bucket and then flow to the suspended pipe through the connecting pipe as the water volume increases subsequently, and then flow out from the drain pipe. A protective cover is installed above the drainage box, and the protective cover is fixed and limited by setting an installation block. At the same time, the drainage rack can be limited by the first limiting plate. When the rain falls on the upper part of the protective cover, it can directly flow into the inside of the internal filter cylinder along the protective cover to participate in the filtration. In this way, the rainwater on the roof will pass through the triple filtration of the first water inlet, the third water inlet and the internal filter cylinder. Larger dust or sundries will directly remain outside the drainage box and will not enter the inside of the drainage box to cause blockage. Relatively small dust and the like will be filtered a second time inside the internal filter cylinder to ensure that there will be no blockage problem. The rainwater flowing down from above will also be filtered inside the internal filter cylinder, which improves the filtering performance and anti-blocking performance of the device, and avoids affecting the normal use of the device due to the blockage of foreign objects. By setting the installation block, the first limiting plate and the fixing block, it is convenient for the daily maintenance work of the staff. During maintenance, the device can be disassembled and cleaned more conveniently, preventing the drainage performance from being affected due to the accumulation of internal dust.

[0007] As a preferred technical solution of the present application, a sedimentation tank is arranged inside the water guide groove, and a limiting block is arranged outside the drainage box, and the limiting block is located above the first water inlet.

[0008] By adopting the above technical solution, by setting the sedimentation tank, the water flowing from the water guide groove to the drainage box can be sedimented in the sedimentation tank, and the large impurities contained in the water are sedimented into the inside of the sedimentation tank to prevent blockage. Setting the limiting block can limit the large sundries to prevent the sundries that are not sedimented in time from blocking the first water inlet, which improves the practicability of the device.

[0009] As a preferred technical solution of the present application, clamping blocks are installed on both sides below the protective cover, and the clamping blocks are clamped to the drainage box. A connecting block is installed below the first limiting plate, and the connecting block is clamped to the protective cover.

[0010] By adopting the above technical solution, by setting the clamping blocks and the connecting blocks, the device can be more stable during use, preventing the device from being damaged due to abnormal phenomena.

[0011] As a preferred technical solution of the present application, a filter screen is arranged above the inner side of the drainage rack, and a second limiting plate is installed above the filter screen.

[0012] By adopting the above technical solution, the water above can be filtered by setting a filter screen, and debris can be prevented from entering the interior of the drainage rack during normal placement, improving the practicality of the device.

[0013] As a preferred technical solution of the present application, a plurality of second water inlets are provided inside the protective cover.

[0014] By adopting the above technical solution, by setting the second water inlets, the speed of rainwater entering the device can be accelerated in the case of heavy rainfall, and the drainage speed of the device can be increased.

[0015] As a preferred technical solution of the present application, a water guide inclined plate is installed above the first structural plate.

[0016] By adopting the above technical solution, by setting the water guide inclined plate, it can effectively help the first structural plate to drain water, prevent damage to the house caused by water remaining above the first structural plate, and improve the practicality of the device.

By setting the filter port, debris inside the water can be filtered. Since the water will flow out from the water outlet to the interior of the siphonic rainwater bucket and then to the suspended pipe through the connecting pipe as the water volume increases later, and then flows out from the drain pipe. A protective cover is installed above the drainage tank. The protective cover is fixed and limited by setting installation blocks. At the same time, the drainage rack can be limited by the first limiting plate. When rainwater falls on the protective cover, it can directly flow into the interior of the internal filter cylinder along the protective cover to participate in filtration. In this way, the rainwater on the roof will pass through the triple filtration of the first water inlet, the third water inlet and the internal filter cylinder.

Relatively small dust and the like will be filtered for the second time inside the internal filter cylinder to ensure that there will be no blockage problem. The rainwater flowing down from above will also be filtered inside the internal filter cylinder. In this way, the filtering performance and anti-blocking performance of the device are improved, and the normal use of the device is prevented from being affected by the blockage of foreign objects. By setting installation blocks, the first limiting plate and fixing blocks, it is convenient for the daily maintenance work of the staff.
