Description

Technical Field

[0001] This application relates to the field of urban building roof renovation technology, and in particular to a prefabricated urban building roof system. Background Technology

[0002] Prefabricated construction is a new type of building that is being vigorously promoted in my country. Prefabricated construction is fast, less affected by weather conditions, and produces very little construction waste. However, this construction method has certain limitations; it is less commonly used in high-rise buildings and has certain restrictions on the size of components. Therefore, besides prefabricated wall panels, prefabricated roofs are the most commonly used prefabricated building materials. With the acceleration of urbanization, the sixth facade of the city (i.e., prefabricated urban building roofs) is an important part of the urban skyline, and its aesthetics and functionality are receiving increasing attention.

[0003] However, existing roofs generally suffer from problems such as monotonous design, high maintenance costs, and low energy efficiency. Especially in cities with abundant natural landscape resources, roof space has failed to fully realize its potential, becoming a bottleneck for improving the city's image. Therefore, an improvement is now being made to a prefabricated urban building roof system. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this application provides a prefabricated urban building roof system, which overcomes the shortcomings of the existing technology and aims to solve the problems that existing roofs generally have, such as simple design, high maintenance costs, and low energy efficiency. The roof space has not been able to fully realize its potential and has become a bottleneck for improving the city's image.

[0005] To achieve the above objectives, this application provides the following technical solution: a prefabricated urban building roof system, comprising a building roof, a planting box, a photovoltaic power generation mechanism, and a power distribution cabinet. A rainwater storage box is fixedly installed on the upper surface of the building roof to the right of the planting box. A rainwater collection hopper is fixedly connected to the top of the rainwater storage box. An irrigation unit is provided between the planting box and the rainwater storage box. The irrigation unit includes a water pump. The inlet of the water pump is fixedly connected to the outlet of the rainwater storage box through a water pipe. An irrigation pipe is fixedly connected to the outlet of the water pump. The irrigation pipe is located inside the planting box and has several nozzles fixedly installed on its upper surface.

[0006] By adopting the above technical solution, planting boxes are set on the top of the building roof and easy-to-maintain plant species are planted inside. This not only beautifies the environment but also effectively absorbs rainwater, reduces the heat island effect, and improves air quality. Rainwater is collected and stored through the cooperation between the rainwater collection hopper and the rainwater storage tank. The rainwater is pumped out of the rainwater storage tank and delivered to the sprinkler heads through the irrigation pipe for irrigation, achieving efficient use of water resources. Solar energy is converted into electricity through the cooperation between the photovoltaic power generation mechanism and the distribution cabinet to supply the roof system for daily use. In other words, this utility model revitalizes the space of the building roof through innovative design, forming a building roof that integrates aesthetics, ecology, and energy conservation.

[0008] By adopting the above technical solution, when the liquid level sensor detects that the remaining water in the rainwater storage tank is insufficient and the next irrigation work cannot be carried out normally, the liquid level sensor sends a start signal to the water replenishment pump to control its start, and the water replenishment pump replenishes the rainwater storage tank with tap water for irrigation.

[0009] As a preferred technical solution of this application, a filter screen is fixedly installed on the top of the rainwater collection hopper, and filter cotton is provided inside the rainwater collection hopper.

[0010] By adopting the above technical solution, rainwater is filtered through filter screens and filter cotton, reducing impurities in the rainwater.

[0011] As a preferred technical solution of this application, the side wall of the rainwater storage tank is fixedly connected to an overflow pipe above the water supply pipe.

[0012] By adopting the above technical solution, excess rainwater can be safely discharged through the overflow pipe, preventing damage caused by overfilling of the rainwater storage tank.

[0013] As a preferred technical solution of this application, the inside of the planting box is lined with earthwork cloth, a support block is fixedly installed at the bottom of the planting box, and a gap is left between the planting box and the building roof through the support block. An overflow hole is opened through the inner bottom wall of the planting box.

[0014] By adopting the above technical solutions, the design of the support block and overflow hole helps to prevent excessive water accumulation in the planting box, protect the plant roots from damage, ensure the respiration of the plant roots, avoid root hypoxia, and prevent the loss of planting soil by setting up the soil cover.

[0015] As a preferred technical solution of this application, the photovoltaic power generation mechanism includes a concrete foundation poured on the top of the building roof, an installation frame fixedly installed on the top of the concrete foundation, the installation frame being assembled by welding square steel, and a photovoltaic panel fixedly installed on the top of the installation frame.

[0016] By adopting the above technical solution, photovoltaic panels are installed at an angle on the top of the building roof through the cooperation between the concrete foundation and the mounting frame, and the photovoltaic panels convert light energy into electrical energy.

[0017] As a preferred technical solution of this application, the photovoltaic panel is electrically connected to the distribution cabinet, and the distribution cabinet is electrically connected to the outlet pump and the makeup pump.

[0018] By adopting the above technical solution, solar energy is converted into electrical energy through photovoltaic panels to form direct current (DC). The power distribution cabinet can convert DC to alternating current (AC) and regulate the voltage and frequency to ensure that the electrical energy can meet the usage requirements of the outlet pump and the replenishment pump.

[0019] As a preferred technical solution of this application, both the rainwater storage tank and the rainwater collection hopper are made of stainless steel.

[0020] By adopting the above technical solution, stainless steel material has high strength and is not easily corroded, so rainwater storage tanks and rainwater collection hoppers made from it are not easily damaged and have a long service life.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. In this utility model, by setting up planting boxes on the top of the building roof and planting easy-to-maintain plant species inside, not only can the environment beautify, but rainwater can also be effectively absorbed, the heat island effect reduced, and air quality improved.

In other words, this utility model revitalizes the space of the building roof through innovative design, forming a building roof that integrates aesthetics, ecology, and energy saving.

[0023] 2. In this utility model, when the liquid level sensor detects that the remaining water in the rainwater storage tank is not enough to carry out the next irrigation work normally, the liquid level sensor sends a start signal to the water replenishment pump to control its start.
