Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a roof rainwater hopper structure. Background Technology

[0002] Due to factors such as weather, water often accumulates on roofs. To facilitate the drainage of water from the roof, the leveling and sloping layer of the roof is usually designed with a certain slope, ultimately sloping towards the drainage outlet, so that the water on the roof flows into the rainwater pipe and is drained away.

[0003] In the organized drainage system of a roof, the key component is the rainwater hopper; existing rainwater hoppers are prone to clogging, which affects their drainage function. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a roof rainwater hopper structure, which aims to solve the technical problem that existing rainwater hoppers are prone to clogging and affect the drainage function of the rainwater hopper.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] One embodiment of this utility model provides a roof rainwater hopper structure, including:

[0007] The drainage body is installed on a wall with a drainage outlet; the drainage body has a bent structure, the water outlet of the drainage body is a vertical structure, the water inlet of the drainage body is a drainage inlet, and the drainage inlet is located inside the drainage outlet.

[0008] A steel water hopper is installed on the outer wall of the wall and is connected to the bottom of the water outlet of the main drainage unit.

[0009] The drainage body includes an overflow channel and a drainage channel. The overflow channel is located outside the drainage channel. A filter cartridge is installed at the water inlet of the drainage channel. The filter cartridge is used to filter the rainwater before it passes through the drainage channel. This pre-filtration of the rainwater can prevent blockage inside the rainwater hopper structure and reduce maintenance costs.

[0010] Furthermore, the drainage channel is equipped with a grating at the water inlet, and the grating has strip channels that can also ensure the discharge of rainwater, and the grating itself also has a filtering function.

[0011] A cleaning rod is also fixedly installed on the grille;

[0012] The grille is made of stainless steel, and the width of the grille's strip channels can be adjusted according to actual drainage needs.

[0013] Furthermore, the filter cartridge is rotatably mounted on the grid, and the cleaning rod cooperates with the outer wall of the filter cartridge. That is, when the filter cartridge rotates, the cleaning rod can clean the deposits on the filter surface of the outer wall of the filter cartridge.

[0014] Furthermore, a connecting shaft is coaxially fixedly connected to the filter cartridge, and the other end of the connecting shaft extends through and into the overflow channel. An impeller is installed on the connecting shaft located in the overflow channel.

[0015] Furthermore, the filter cartridge is detachably connected to the end of the connecting shaft, and the filter cartridge is installed on the grid in a detachable connection manner.

[0016] Furthermore, a filter screen is installed at the water inlet of the overflow channel.

[0017] Compared with the prior art, the beneficial effects of this utility model's roof rainwater hopper structure are:

[0018] First, if the drainage channel of this utility model is functioning smoothly, rainwater from the building roof will be discharged into the steel water hopper through the drainage channel; when the drainage channel cannot meet the discharge of rainwater, the water level in the drainage inlet will rise, and drainage will continue through the overflow channel to ensure the drainage effect of the entire rainwater hopper structure.

[0019] Second, the rainwater from the building roof is drained into a steel water tank through the drainage system, and then discharged into the building's groundwater treatment system through the water pipe at the bottom of the steel water tank.

[0020] Third, rainwater from the building roof is normally discharged through the drainage channel. When the grille and filter cartridge become blocked, causing the water level in the drainage inlet to rise, the rainwater from the roof enters the overflow channel and is discharged through the overflow channel. The rainwater passing through the overflow channel will impact the impeller, causing the impeller to rotate. The rotating impeller will cause the filter cartridge to rotate to a certain extent. When the filter cartridge rotates, the cleaning rod will clean the filter material on the filter surface of the filter cartridge. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] like Figure 1 The diagram shown is a structural diagram of a roof rainwater hopper structure provided in an embodiment of the present invention. The roof rainwater hopper structure provided by the present invention includes a drainage body 2, which is installed on a wall 1 with a drainage outlet 11. The wall 1 is generally a parapet wall structure of a building roof, and the drainage outlet 11 is used for roof drainage.

[0030] Furthermore, the drainage body 2 has a bent structure, the water outlet of the drainage body 2 is a vertical structure, and the water inlet of the drainage body 2 is a drainage inlet 23, which is located inside the drain outlet 11.

[0031] The roof rainwater hopper structure of this embodiment also includes a steel hopper 3, which is installed on the outer wall of the wall 1. The steel hopper 3 is connected to the bottom end of the water outlet of the drainage body 2. Through the drainage body 2, the rainwater on the roof of the building is discharged and enters the steel hopper 3. The water pipe at the bottom of the steel hopper 3 is then used to discharge the rainwater into the building's groundwater treatment system.

[0032] Furthermore, in this embodiment of the present invention, the drainage body 2 includes an overflow channel 21 and a drainage channel 22. The overflow channel 21 is located outside the drainage channel 22. Under normal circumstances, if the drainage function of the drainage channel 22 is smooth, rainwater from the building roof will be discharged into the steel water hopper 3 through the drainage channel 22. When the drainage channel 22 cannot meet the discharge of rainwater, the water level in the drainage inlet 23 rises. At this time, drainage continues through the overflow channel 21.

[0033] Please continue to refer to Figures 1-4 In this embodiment of the utility model, a filter cylinder 42 is provided at the water inlet of the drainage channel 22. The filter cylinder 42 is used to filter the rainwater before it passes through the drainage channel 22. The pre-filtration of the rainwater can prevent the internal blockage of the rainwater hopper structure and reduce maintenance costs.

[0034] Preferably, in this embodiment of the present invention, a grille 5 is provided at the water inlet of the drainage channel 22. The grille 5 has a strip channel 51, which can also ensure the discharge of rainwater. The grille 5 itself also has a filtering function.

[0035] In addition, a cleaning rod 52 is fixedly installed on the grid 5; in this embodiment, the filter cartridge 42 is rotatably installed on the grid 5, and the cleaning rod 52 cooperates with the outer wall of the filter cartridge 42. That is, when the filter cartridge 42 rotates, the cleaning rod 52 can clean the deposits on the filter surface of the outer wall of the filter cartridge 42.

[0036] Please continue to refer to Figures 1-4 In this embodiment of the utility model, a connecting shaft 41 is coaxially fixedly connected to the filter cartridge 42, and the other end of the connecting shaft 41 extends through and into the overflow channel 21. An impeller 4 is installed on the connecting shaft 41 located in the overflow channel 21.

[0037] In an optional embodiment, the filter cartridge 42 and the end of the connecting shaft 41 can be detachably connected, and the filter cartridge is installed on the grid 5 in a detachable connection manner, which facilitates the cleaning and replacement of the filter cartridge 42.

[0038] The detachable connection method provided in the embodiments of this disclosure can be a bolt connection, and is not specifically limited thereto;

[0039] In an optional embodiment, the grille 5 is made of stainless steel, and the width of the strip channel 51 of the grille 5 can be adjusted according to actual drainage needs.

[0040] Understandably, in some cases, rainwater from the building roof is normally discharged through the drainage channel 22. When the grille 5 and filter cartridge 42 are blocked, causing the water level in the drainage inlet 23 to rise, the rainwater from the roof enters the overflow channel 21 and is discharged through the overflow channel 21. The rainwater passing through the overflow channel 21 will impact the impeller 4, causing the impeller 4 to rotate. The rotating impeller 4 will cause the filter cartridge 42 to rotate to a certain extent. When the filter cartridge 42 rotates, the cleaning rod 52 will clean the filter material on the filter surface of the filter cartridge 42.

[0041] Preferably, multiple cleaning rods 52 can be provided. As long as the filter cartridge 42 rotates to a certain extent, multiple cleaning rods 52 can simultaneously clean the surface of the filter cartridge 42, so that the filter cartridge 42 can restore the water-passing effect and ensure the smooth progress of the drainage process.

[0042] Please continue to refer to Figure 1 In this embodiment of the present invention, a filter screen 6 is provided at the water inlet of the overflow channel 21. The filter screen 6 is also used for filtration, which also prevents debris from entering the overflow channel 21 and causing blockage when water flows through it.

[0043] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.

[0044] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.

[0045] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
