[0015] The utility model has the following beneficial effects:

[0016] The environment benefit is remarkable:

[0017] Carbon emission reduction and carbon sink improvement: the application of zero-carbon planting concept to the slope roof effectively reduces carbon emissions caused by planting activities through optimizing energy use (such as zero-carbon photovoltaic power generation for power supply of the spraying system) and resource management in the planting process. At the same time, the photosynthesis of slope roof vegetation continuously absorbs carbon dioxide, increasing the carbon sink in the building environment, which helps to balance the carbon budget of the building itself and the surrounding area, and has a positive significance for mitigating climate change.

[0018] Ecological environment improvement: the increase of slope roof vegetation coverage area significantly improves the local ecological environment of the city. Plants purify the air, improve air quality, regulate the local climate, reduce the urban heat island effect, and create a more comfortable living environment for urban residents through the effects of absorbing harmful gases, adsorbing particulate matter, and reducing noise. They also provide habitats and breeding sites for birds, insects and other organisms, promoting the development of urban biodiversity.

[0019] Energy and resource utilization is efficient:

[0020] Energy self-sufficiency: the zero-carbon photovoltaic power generation device fully utilizes the top space of the slope roof to convert solar energy into electric energy, providing power support for the entire automatic spraying device. Not only does it meet the operational needs of water pumps, controllers and other equipment in the spraying system, achieving self-sufficiency of system energy, reducing dependence on traditional grid power, reducing carbon emissions in the process of energy production and transmission, but also supplying excess electricity to other electrical equipment in the building, improving the comprehensive utilization efficiency of energy.

[0021] Optimized management of water resources: the water storage tank in the automatic water storage and spraying device can effectively collect the rainwater resources of the slope roof, realizing full utilization of natural precipitation and reducing dependence on municipal water supply or other external water resources. Combined with the liquid level sensor and the reclaimed water supply system, water resources can be reasonably allocated according to the water level in the storage tank and the spraying demand, avoiding waste and shortage of water resources. At the same time, the precise humidity sensor controls the amount and time of spraying water to ensure that plants get the right amount of water while minimizing ineffective evaporation and loss, improving the utilization efficiency of water resources.

[0022] Planting benefits are improved:

[0023] Precise irrigation ensures plant growth: The automatic sprinkler system, based on soil moisture sensors and preset parameters, can accurately determine the water needs of plants and achieve precise irrigation. This avoids the problems of poor plant growth or death caused by the difficulty of controlling water quantity in traditional manual sprinkling, providing a stable and suitable water environment for slope roof plants, promoting the healthy growth of plants, and improving the success rate of planting and the survival rate of plants, which is conducive to creating a diversified and high-quality slope roof planting landscape.

[0024] Intelligent management reduces labor intensity: The entire system realizes multifunctional linkage by the controller, achieving automatic operation and intelligent management. Without frequent manual intervention, the labor intensity and labor cost in the planting management process are greatly reduced. Management personnel only need to perform regular equipment inspection and maintenance to ensure the normal operation of the system, improving the efficiency and convenience of planting management.

[0025] Building performance optimization:

[0026] Heat insulation reduces energy consumption: The slope roof vegetation layer and water storage layer play a role in heat insulation in different seasons. In summer, vegetation and water absorb and block solar radiation heat, reducing heat transfer into the building interior and reducing air conditioning cooling load; in winter, vegetation and water storage layer can also play a certain role in heat preservation, slowing down the loss of indoor heat and reducing heating energy consumption. Through this passive energy-saving measure, the energy consumption of the building is effectively reduced, and the energy-saving performance and comfort of the building are improved.

[0027] Prolong the service life of the building: The soil retaining and filtering device effectively prevents the damage of slope roof soil loss and rainwater erosion to the roof structure. By filtering rainwater and stabilizing slope soil, the integrity of the roof waterproof layer and structural layer is protected, reducing problems such as roof leakage and structural deformation caused by soil loss, prolonging the service life of the building, and reducing building maintenance and repair costs.

[0028] Enhance urban resilience:

[0029] Relieve the pressure of waterlogging: As a micro application of the concept of sponge city, the slope roof water storage device can collect and store a large amount of rainwater in the rainy season, effectively reducing the runoff of rainwater and reducing the drainage pressure of the municipal drainage system. In cooperation with other rainwater management facilities in the city, it helps to alleviate the problem of urban waterlogging and improve the resilience and disaster resistance of the city in dealing with extreme rainfall weather.

[0030] Promote the sustainable development of city: the application of zero-carbon planting slope roof automatic spraying device integrates the benefits of ecology, energy, building, water resources and other aspects, and promotes the development of city to green, low carbon and sustainable direction. It provides an innovative solution for the city to realize ecological environment protection, resource efficient utilization, building function optimization and resident life quality improvement under the condition of limited land resources, and promotes the overall sustainable development process of city.

When the water level is too high, the excess rainwater can be discharged through the overflow port to prevent the water storage tank 221 from overflowing; when the water level is too low and there is no precipitation for a long time, the controller 4 can open the reclaimed water switch to introduce the reclaimed water as a water source through the water inlet to ensure the continuous and stable operation of the spraying system, greatly improves the utilization rate of water resources, and meets the environmental protection and sustainable development concept.

[0045] Specifically, in the embodiment, the zero-carbon photovoltaic power generation device 3 comprises a photovoltaic roof panel 31, an inverter 32, a storage battery 33, and a power distribution room 34; the photovoltaic roof panel 31 is installed on the top of the slope roof 5 through the photovoltaic roof panel base 35; the power distribution room 34 is arranged at the back of the slope roof 5; the inverter 32 and the storage battery 33 are arranged in the power distribution room 34 respectively; the photovoltaic roof panel 31 is electrically connected with the storage battery 33 through the inverter 32; and the storage battery 33 is electrically connected with the water pump 223 and the controller 4 respectively.
