[0002] A green building refers to a building that maximally saves resources, including energy conservation, land conservation, water conservation, material conservation, etc., protects the environment and reduces pollution during the entire life cycle of the building, provides a healthy, comfortable and efficient use space for people, and coexists in harmony with nature. Green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization. It is the sharing of interests between humans and nature, between the present and the future, and is a means of sustainable development construction. Currently, in order to reduce the energy consumption of buildings, photovoltaic panels are usually installed on the roofs of houses, and the solar energy is converted into electrical energy for the use of electrical appliances inside the buildings. If the roof is not cleaned for a long time, more impurities and dust will accumulate, which will have a certain blocking effect on the photovoltaic panels and affect the photovoltaic effect of the photovoltaic panels. Therefore, it is necessary to clean the roof. Currently, manual cleaning and manual flushing are usually adopted. Manual cleaning is more cumbersome, time-consuming and laborious, and there are also potential safety hazards. Manual flushing is relatively wasteful of water resources. Therefore, we urgently need a new roof cleaning method. Content of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Embodiment 1

[0036] Refer to Figures 1 - 3 , a new type of photovoltaic roof for green buildings, which includes a roof body 1, a top frame 2, a water tank 15, an inclined surface 25, and a wiping unit. The roof body 1 is located at the top of the wall; the top frame 2 is placed on the top of the roof body 1. There are two water tanks 15, which are respectively located on both sides inside the top frame 2. There are two inclined surfaces 25, which are respectively placed on both sides of the top of the top frame 2; a plurality of photovoltaic panels 3 are embedded on each of the two inclined surfaces 25. Each inclined surface corresponds to a wiping unit.

[0037] The wiping unit includes a wiping plate 4, a spraying mechanism, a sliding mechanism, and a driving mechanism.

[0038] The wiping plate 4 is placed at the highest point of the inclined surface 25 and is installed on the spraying mechanism. The spraying mechanism includes a diversion pipe 10, branch pipes 11, nozzles 12, a movable pipe 13, and a water guiding hose 16. The diversion pipe 10 is placed on the inclined surface 25 and in front of the wiping plate 4; and the front end of the diversion pipe 10 is in a blocked state, and the rear end is connected to one end of the movable pipe 13. In this embodiment, the wiping plate 4 is fixed to the diversion pipe 10 so as to move together. There are multiple branch pipes 11, which are evenly installed on the diversion pipe 10, and each branch pipe 11 is provided with a nozzle 12. The other end of the movable pipe 13 passes through the sliding groove 14 on the top frame 2 and is connected to one end of the water guiding hose 16 inside the top frame 2, and the other end of the water guiding hose is connected to the water tank through a water pump. In this embodiment, the movable pipe 13 is a rigid pipe, which can slide in the sliding groove 14, and the sliding groove 14 can be designed as an inclined groove, and its inclination angle is the same as that of the inclined surface 25 to ensure the distance between the nozzle 12 and the roof, and thus ensure the spraying and flushing effect.

[0039] There are two sliding mechanisms, which are respectively located on both sides of the diversion pipe 10, and it includes a guiding groove 6 and an L-shaped plate 5. The guiding groove 6 is provided on the top frame 2. One end of the L-shaped plate 5 is connected to the diversion pipe 10, and the other end is placed in the guiding groove 6, and the L-shaped plate 5 can slide in the guiding groove 6. In this embodiment, the guiding groove 6 can be designed as an inclined groove, and its inclination angle is the same as that of the inclined surface 25, so as to drive the spraying mechanism and the wiping plate 4 to move along the inclined surface 25 of the roof.

[0040] The driving mechanism includes a driving motor 8, a lead screw 9, and a movable plate 7.

The movement of the movable plate 7 can ensure the synchronous movement of the movable pipe 13 and improve the stability between various structures.

[0042] In this embodiment, the structure in which the wiping plate 4 contacts the surface of the inclined plane 25 can be a soft structure such as a sponge or bristles.

[0043] Embodiment 2

[0044] See Figure 4 , different from Embodiment 1, the new type of photovoltaic roof for green buildings further includes a rainwater collection mechanism for collecting rainwater on the inclined plane 25. The rainwater collection mechanism includes a water inlet groove 17, a first filter screen 18, a water storage frame 19, a water guiding pipe 23, a partition plate 20, a water guiding groove, and a second filter screen 22. The water inlet groove 17 is placed at the bottom edge of the inclined plane 25, near the top frame 2. The first filter screen 18 is placed at the water inlet groove 17. The water storage frame 19 is placed inside the top frame 2, below the water inlet groove 17, and its bottom end is connected to the water tank 15 through the water guiding pipe 23. The partition plate 20 is installed inside the water storage frame 19 and is located below the water inlet groove 17. One end of the partition plate 20 is connected to the frame wall of the water storage frame 19, and the other end is connected to the top frame 2; on the side of the top frame 2, a drainage groove 21 is opened at the position of one end of the partition plate 20; a water guiding groove 26 is opened on the partition plate 20, and the second filter screen 22 is installed at the water guiding groove 26; in this embodiment, in order to facilitate drainage, the upper surface of the partition plate can be designed as an inclined plane, and the inclined plane slopes downward in the direction of the drainage groove 21 to drain excess water.

[0045] In this embodiment, a water guiding plate 24 can be inclinedly arranged below the water inlet groove 17. The upper end of the water guiding plate 24 is connected to the top frame 2 on the side of the water inlet groove 17; the lower end of the water guiding plate 24 is far from the drainage groove 21 and has a gap with the frame wall of the water storage frame 19. The water guiding plate 24 makes the rainwater entering from the water inlet groove 17 first flow to one end of the partition plate 20, and then flow along the other end direction of the partition plate 20 (the direction of the drainage groove 21). During the flowing process, it will pass through the water guiding groove 26, thus facilitating the collection and filtration of rainwater.

[0046] In rainy weather, when the rainwater flows downward along the inclined plane 25, it will pass through the water inlet groove 17, and the first filter screen 18 on the water inlet groove 17 can block impurities from entering the water storage frame 19, and the impurities will flow out along the inclined plane 25; the rainwater entering the water storage frame 19 will fall on the partition plate 20, and then enter the bottom end of the water storage frame 19 through the water guiding groove 26 on the partition plate 20. The setting of the second filter screen 22 can isolate smaller impurities from entering the bottom end of the water storage frame 19, and the smaller impurities will be discharged from the drainage groove 21 along with part of the water flow. The rainwater entering the bottom end of the water storage frame 19 will be introduced into the water tank 15 through the water guiding pipe 23 for storage. Corresponding drain pipes or other pipelines can be equipped on the water tank 15 to facilitate other functions of the rainwater and prevent the water tank 15 from storing too much water.

[0047] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0048] It should be understood that those of ordinary skill in the art can make improvements or transformations based on the above description, and all such improvements and transformations shall fall within the protection scope of the appended claims of this utility model.
