Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a special device for water supply and drainage in buildings. Background Technology

[0002] Building drainage typically involves installing drainage ditches on the outside of the roof to collect rainwater, and then draining the water from the drainage ditches into vertical drainage pipes installed on the outside of the building through drainage outlets, from where it is discharged or collected for reuse.

[0003] Chinese Patent No. CN220888826U discloses a building water supply and drainage device, including a collection tank, a collection chamber with an upward opening inside the collection tank, a slag discharge port on the side wall of the collection tank, a top plate at the opening of the collection chamber, and a filter assembly that can be raised and lowered inside the collection chamber. The filter assembly includes a filter plate, and the outer edge of the filter plate is provided with a blocking ring for sealing the slag discharge port. By incorporating a collection chamber, an inlet pipe, and a filter assembly, rainwater entering the collection chamber through the inlet pipe can be filtered by the filter assembly. Compared to existing drainage devices that do not have a filter assembly, this invention can filter the rainwater entering the collection chamber by setting up a filter assembly, preventing impurities from accumulating in the collection chamber and causing pipe blockage. However, the aforementioned patent has a poor sealing effect on the slag discharge port using a plugging ring, which easily leads to water leakage during the drainage filtration process. Furthermore, the scraper located inside the collection tank has a poor cleaning effect on the filter plate, resulting in slag leakage, which in turn affects the cleaning effect of the filter plate. Therefore, we propose a special water supply and drainage device for buildings to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a special device for water supply and drainage in buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A special water supply and drainage device for buildings includes a collection tank, two limiting members on the outside of the collection tank, two lifting members on the outside of the collection tank, a sealing cover on the top of the collection tank, a connecting column connected to the bottom surface of the sealing cover, a filter screen connected to the bottom surface of the connecting column, a sewage pipe connected to the bottom surface of the collection tank, a sewage discharge electric butterfly valve connected to the outer surface of the sewage pipe, a drain pipe connected to the outer surface of the collection tank, a drain electric butterfly valve connected to the outer surface of the drain pipe, and a controller installed on the outer surface of the collection tank.

[0007] In a further embodiment, each of the two lifting components includes two support plates connected to the outer surface of the collection tank. An electric cylinder is installed on the upper surface of each of the two support plates. The telescopic ends of the two electric cylinders are connected to a lifting plate. The bottom surface of the lifting plate is connected to the bottom surface of the sealing cover.

[0008] In a further embodiment, the bottom surface of the lifting plate is connected to two protective covers, and the two electric cylinders are respectively located inside the two protective covers.

[0009] In a further embodiment, both of the limiting members include two reinforcing plates connected to the outer surface of the collection tank, the upper surfaces of the two reinforcing plates are connected to limiting slides, the inner walls of the two limiting slides are slidably connected to limiting sliders, and the sides of the two limiting sliders that are close to each other are respectively connected to the outer surfaces of the two protective covers.

[0010] In a further embodiment, an annular seat is connected to the outer surface of the collection tank, and an annular plate is connected to the bottom surface of the sealing cap, with the bottom end of the annular plate extending into the interior of the annular seat.

[0011] In a further embodiment, the outer surface of the collection tank is connected to a water inlet pipe, and the outer surface of the water inlet pipe is connected to a water inlet flange.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes two lifting components on the outside of the collection tank to move the lifting plate, sealing cover, connecting column, and filter screen upwards. This provides power for the lifting and lowering of the filter screen until it moves above the collection tank and is at the same height as the top of the tank. At this point, cleaning tools can directly clean the filter screen from all angles. Compared to traditional internal cleaning methods, this method can more thoroughly remove impurities, prevent sludge leakage, ensure the filtration effect of the filter screen, and facilitate subsequent drainage. In addition, controlling the closing of the drain electric butterfly valve and the opening of the sewage electric butterfly valve facilitates the cleaning of particulate matter settled inside the collection tank, improving the cleaning effect inside the collection tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4In this utility model, a special device for water supply and drainage in buildings includes a collection tank 1. Two limiting members 2 and two lifting members 3 are provided on the outside of the collection tank 1. A sealing cover 4 is provided on the top of the collection tank 1. A connecting column 5 is connected to the bottom surface of the sealing cover 4, and a filter screen 6 is connected to the bottom surface of the connecting column 5. A drain pipe 9 is connected to the bottom surface of the collection tank 1, and a drain electric butterfly valve 10 is connected to the outer surface of the drain pipe 9. A drain pipe 7 is connected to the outer surface of the collection tank 1, and a drain electric butterfly valve 8 is connected to the outer surface of the drain pipe 7. A controller 15 is installed on the outer surface of the collection tank 1. The collection tank 1 provides the installation base for other components and, together with the filter screen 6, intercepts impurities in the water. Through the cooperation of the limiting members 2 and the lifting members 3, the lifting and lowering of the sealing cover 4 and the filter screen 6 can be controlled. The drain pipe 9 and the drain pipe 7 are responsible for discharging impurities and filtered water, respectively. The electric butterfly valve controls the opening and closing of the pipeline, and the controller 15 is used to coordinate the operation of each component to achieve automated operation.

[0023] In a further embodiment, each of the two lifting components 3 includes two support plates 301 connected to the outer surface of the collection tank 1. An electric cylinder 302 is installed on the upper surface of each of the two support plates 301. The telescopic ends of the two electric cylinders 302 are connected to a lifting plate 16. The bottom surface of the lifting plate 16 is connected to the bottom surface of the sealing cover 4. Two protective covers 303 are connected to the bottom surface of the lifting plate 16. The two electric cylinders 302 are located inside the two protective covers 303 respectively. When it is necessary to clean the filter screen 6, the controller 15 controls the electric cylinders 302 to extend, driving the lifting plate 16 to rise, thereby lifting the sealing cover 4, the connecting column 5 and the filter screen 6 together upward, so as to facilitate the cleaning of the lifted filter screen 6. The electric cylinders 302 can be protected by the protective covers 303.

[0024] In a further embodiment, each of the two limiting components 2 includes two reinforcing plates 201 connected to the outer surface of the collection tank 1. The upper surface of each of the two reinforcing plates 201 is connected to a limiting slide 202. The inner wall of each of the two limiting slides 202 is slidably connected to a limiting slider 203. The side of each limiting slider 203 that is close to the other is connected to the outer surface of each of the two protective covers 303. During the operation of the lifting component 3, the limiting slider 203 slides within the limiting slide 202, restricting the movement direction of the protective cover 303, the lifting plate 16 and the sealing cover 4, ensuring that they can only rise and fall in the vertical direction, avoiding deviation and shaking, ensuring the stability and safety of the device operation, and at the same time assisting the lifting component 3 in accurately controlling the lifting height of the filter screen 6.

[0025] In a further embodiment, an annular seat 14 is connected to the outer surface of the collection tank 1, and an annular plate 13 is connected to the bottom surface of the sealing cover 4. The bottom end of the annular plate 13 extends into the interior of the annular seat 14. An inlet pipe 11 is connected to the outer surface of the collection tank 1, and an inlet flange 12 is connected to the outer surface of the inlet pipe 11. Through the cooperation between the annular seat 14 and the annular plate 13 on the bottom surface of the sealing cover 4, and with a sealing gasket installed between them, the top of the collection tank 1 can be sealed to prevent water leakage and the entry of debris. Through the inlet pipe 11 and the inlet flange 12, it can be connected to an external water source pipe to introduce water to be filtered into the device, which facilitates the filtration of water.

[0026] The working principle of this utility model is as follows: When water enters the collection tank 1 through the inlet pipe 11 and the inlet flange 12, the water first passes through the filter screen 6, which filters out impurities in the water. Then, it is discharged from the collection tank 1 through the drain pipe 7 and flows into the external drainage system. When the filter screen 6 needs to be cleaned, the lifting component 3 is controlled by the controller 15 to move the lifting plate 16 and the sealing cover 4 upward, and at the same time, the connecting column 5 and the filter screen 6 are moved upward until the filter screen 6 is moved above the collection tank 1 and is at the same level as the top of the collection tank 1. Then, with the help of cleaning tools, it is easy to deeply clean the debris above the filter screen 6. In addition, the opening of the sewage discharge electric butterfly valve 10 allows the settled impurities to be discharged from the collection tank 1 through the sewage discharge pipe 9. After the sewage discharge and drainage operations are completed, the controller 15 controls the electric cylinder 302 to retract, causing the sealing cover 4 to descend, and the annular plate 13 to re-insert into the annular seat 14 to seal the collection tank 1, waiting for the next drainage operation.
