[0024] To enable those skilled in the art to more clearly understand the purpose, technical solutions, and advantages of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] Reference Figures 1 to 4 , Figure 1 and Figure 4 A specific embodiment of the outdoor drainage system of this utility model is shown. In the embodiment shown in the accompanying drawings, the outdoor drainage system is applied to a building balcony or rooftop, including a drainage pipe 30, a wall-mounted floor drain 10, a water level sensor 50, and a controller. The wall-mounted floor drain 10 is installed on the building side wall 3, and its lower end is located at the connection between the building side wall 3 and the ground 2 to avoid water residue on the ground 2 when draining water. A first opening and closing device is provided at the inlet of the wall-mounted floor drain 10. In this embodiment, the drainage pipe 30 is pre-embedded under the ground 2, and the wall-mounted floor drain 10... The outlet of the drain is connected to the drainage pipe 30; the water level sensor 50 is located next to the wall drain 10 to detect whether the water level reaches or exceeds the top of the wall drain 10; the controller is electrically connected to the water level sensor 50 and the first opening and closing device, and is used to control the first opening and closing device to push outward when the water level reaches or exceeds the top of the wall drain 10, so as to open the inlet of the wall drain 10, and can also drain the water accumulated on the balcony or roof when the wall drain 10 is blocked by leaves, garbage, etc. Preferably, in this embodiment, the controller can be installed on the wall of the balcony or roof through a control box, and the controller can be implemented based on a microcontroller or single-chip microcomputer.
[0026] Understandably, in this invention, the floor 2 refers to the floor of a balcony, the floor of any floor, or the floor of the top floor. Based on the above design, the outdoor drainage system of this invention is equipped with a wall-mounted floor drain 10. Because the wall-mounted floor drain 10 is installed on the side wall of the building and its lower end is located at the connection between the side wall 3 and the floor 2, it can drain all the water accumulated on the balcony or roof. When the wall-mounted floor drain 10 is blocked by leaves, garbage, etc., causing the water level to reach or exceed the top of the wall-mounted floor drain 10, the garbage can be pushed outward by the first opening and closing device, and the inlet can be opened to allow the water to drain out from the open inlet, which can prevent water from flowing back into the room, thereby avoiding economic losses and improving the user experience.
[0027] In some embodiments, the outdoor drainage system further includes a floor drain 20, which is disposed on the ground 2. A second opening and closing device is provided at the inlet of the floor drain 20. The outlet of the floor drain 20 is connected to the drainage pipe 30, and the controller is electrically connected to the second opening and closing device. When the detected water level reaches or exceeds the top of the wall-mounted floor drain 10, the controller controls the second opening and closing device to push outwards, thereby opening the inlet of the floor drain 20. Based on this design, this utility model can be configured with dual floor drains, i.e., simultaneously installing a wall-mounted floor drain 10 and a floor drain 20, to better and faster drain accumulated water from balconies or rooftops. The second opening and closing device at the inlet of the floor drain 20 allows the controller to activate and push outwards when the detected water level reaches or exceeds the top of the wall-mounted floor drain 10, thus opening the inlet of the floor drain 20 and accelerating drainage.
[0028] In some embodiments, the first and second opening / closing devices have the same structure. It can be understood that the specific structure of the floor drain 20 and the wall drain 10 are also substantially the same. In this embodiment, both the first and second opening / closing devices include a cover 41 and a driving member 42, such as... Figure 2 As shown, the cover 41 is installed at the inlet of the wall drain 10 / floor drain 20. The driving component 42 is connected to the cover 41 and is used to drive the cover 41 to push out, so that the cover 41 opens the inlet of the wall drain 10 / floor drain 20.
[0029] Specifically, the cover 41 includes a first filter cover 411 and a second filter cover 412. The first filter cover 411 and the second filter cover 412 can be disc-shaped. The first filter cover 411 is fixed to the top edge of the wall drain 10 / floor drain 20. The first filter cover 411 is provided with a plurality of first filter holes 413. The second filter cover 412 is disposed inside the first filter cover 411. The second filter cover 412 is provided with a plurality of second filter holes 414 corresponding to the plurality of first filter holes 413. The driving member 42 is connected to the first filter cover 411 to drive the first filter cover 411 to push out when the detected water level reaches or exceeds the top of the wall drain 10. Preferably, in this embodiment, the driving component 42 may include a cylinder, and the driving component 42 may be installed inside the wall drain 10 via a mounting component 70. The mounting component 70 includes a first mounting plate 71 fixed to the inner wall of the wall drain 10 and a second mounting plate 72 formed by bending upward from the other end of the first mounting plate 71. The cylinder barrel is fixed to the second mounting plate 72. Figure 3 As shown, in this embodiment, the piston rod of the cylinder can be connected to the first filter cover 411 via a connecting rod 73. In some other embodiments, the piston rod can be directly connected to the first filter cover 411. When the detected water level reaches or exceeds the top of the wall drain 10, the piston rod of the cylinder pushes outward, causing the first filter cover 411 connected to the cylinder to push outward (the pushed-out state is as shown). Figure 3 As shown in the diagram, the height of the ejection is approximately 4-5 cm. Based on the above design, during normal operation, the second filter hole 414 and the first filter hole 413 overlap. When leaves, debris, or other debris clog the first filter hole 413, the first filter cover 411 can be ejected outwards by a cylinder, pushing the debris outwards. Water enters through the gap between the first filter cover 411 and the second filter cover 412, flows through the second filter hole 414 into the drain pipe inside the wall drain 10, and is then discharged through the drain pipe 30.
[0030] In this utility model, the water level sensor 50 detects the water level height of the accumulated water. The water level sensor 50 detects the current water level of the accumulated water in the balcony or roof. If the current water level reaches or exceeds the top of the wall drain 10, the water level sensor 50 sends a signal to the controller. The controller controls the drive unit 42 in the first opening and closing device and / or the second opening and closing device to work, so as to push the first filter cover 411 of the cover 41 in the first opening and closing device and / or the second opening and closing device outward.
[0031] Continue to refer to Figure 4In some embodiments, the drainage pipe 30 is a PVC pipe, and an ultraviolet lamp ring 60 is installed at the end of the drainage pipe 30. The ultraviolet lamp ring 60 is connected to a power source via wires to sterilize and disinfect the water flowing through the end of the drainage pipe 30. Furthermore, a waterproof layer can be provided on the surface of the ultraviolet lamp ring 60 to extend its service life. Based on the above design, when the power is turned on, the ultraviolet lamp ring 60 operates to emit ultraviolet light, which sterilizes and disinfects the water flowing through the end of the drainage pipe 30, purifying the discharged water and thus preventing secondary water pollution.
[0032] In summary, this utility model's outdoor drainage system is equipped with a wall-mounted floor drain and a water level sensor. The wall-mounted floor drain has a first opening and closing device at its inlet. When the detected water level reaches or exceeds the top of the wall-mounted floor drain, the controller activates the first opening and closing device to push it outwards, thus opening the inlet. This allows debris such as leaves to be pushed outwards when clogging the drain, and the opening of the inlet allows water to drain out, preventing backflow into the room. A second opening and closing device is also provided for the floor drain, enabling dual-drain drainage for better and faster drainage of water from balconies or rooftops, preventing water residue. Furthermore, an ultraviolet lamp ring is installed at the end of the drainage pipe to sterilize the water discharged, thus preventing secondary water pollution.
