Description

Technical Field

[0001] The invention belongs to the technical field of sponge city construction, and particularly relates to a green roof used in a sponge city. Background Art

[0002] Sponge city, also known as "water-elastic city", refers to a city that can adapt to environmental changes and respond to natural disasters caused by rainwater like a sponge. Its core concept is to achieve the natural accumulation, infiltration and purification of rainwater through six measures of "infiltration, retention, storage, purification, use and discharge", thereby promoting the ecological, safe and sustainable development of the urban water circulation system.

[0003] Sponge cities reduce losses to cities caused by natural disasters such as rain by adapting to environmental changes. However, the numerous buildings in the city will cause rainwater to quickly drain into the green spaces of sponge cities, causing the green spaces of sponge cities to lose their water storage capacity. In addition, most of the rainwater collected on the roofs of existing sponge cities is directly discharged into rainwater pipes. A large amount of rainwater gathers in rainwater wells, causing the runoff of rainwater wells to increase rapidly, increasing the probability of waterlogging in sponge cities.

[0004] As the preferred place for photovoltaic power generation in sponge cities, most of the existing building roofs are built with rooftop photovoltaic structures. However, the buildings in sponge cities are mostly tall. At the same time, with the increase in extreme weather, the roofs of buildings will be impacted by natural disasters such as storms, strong winds, and gusts, which can easily cause damage to the rooftop photovoltaic structures and cause large economic losses.

[0005] In addition, most of the existing sponge city building roofs are used as places for photovoltaic power generation. In order to maintain the rainwater collection capacity of the building roofs, most of the existing photovoltaic green roofs choose to reduce the coverage of the roof photovoltaic structure to leave a certain range for the rainwater collection structure, thereby preventing the roof photovoltaic structure from affecting rainwater collection, resulting in the two being separated from each other, making it difficult to achieve coordinated processing of photovoltaic power generation and rainwater collection.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention can realize photovoltaic power generation, rainwater collection, rainwater storage and green plant maintenance on the roof of the building by constructing a photovoltaic water collection system and a green water storage system on the roof of the building. The photovoltaic water collection system can generate electricity and collect rainwater, and the generated electricity and collected rainwater are stored in the green water storage system. The green plants in the green water storage system can reduce the temperature around the photovoltaic water collection system, reduce the probability of failure of the photovoltaic water collection system due to excessive temperature, and realize the coordinated processing of photovoltaic power generation and rainwater collection; the photovoltaic water collection structure of the present invention can adjust the height and angle as needed, and reduce the impact of storms, strong winds, gusts, etc. on the photovoltaic panel body by lowering the height, which can improve the impact strength and stability of the photovoltaic panel body and enhance the ability of the photovoltaic panel body to cope with storms, strong winds, gusts, etc.; the green water storage system can reduce the impact of extreme weather on the sponge city by storing rainwater and planting green plants, reduce the impact of rainwater on the sponge city, reduce the temperature of the building roof, and improve the livability of the building.

[0018] (2) The tracking structure adjusts the horizontal rotation of the tracking base through the tracking chassis, thereby adjusting the horizontal rotation of the photovoltaic panel body on the tracking base in the opposite direction, so that the photovoltaic panel body can track the direction of light and improve the power generation efficiency of the photovoltaic panel body; the tracking adjuster adopts a tracking telescopic rod and a tracking adjustment part. The tracking adjustment part is connected by a spiral airbag and a tracking spring. The height and tilt angle of the tracking base are adjusted by flexible lifting. When the photovoltaic water collection structure on the tracking base is impacted by storms, strong winds, gusts, etc., it can reduce the impact force on the photovoltaic panel body, thereby improving the ability of the photovoltaic panel to resist external impacts, ensuring the safety of the photovoltaic panel body and preventing damage to the photovoltaic panel body.

[0019] (3) The photovoltaic water collection structure can further adjust the height of the photovoltaic panel body through a photovoltaic bracket that can be raised and lowered and folded, so that the photovoltaic panel body at different positions can be adjusted to different heights according to the power generation demand, meet the lighting needs of each photovoltaic panel body, and improve the power generation efficiency of the photovoltaic water collection structure; when impacted by storms, strong winds, gusts of wind, etc., the photovoltaic panel body can be lowered to the lowest position, making it lower than the height of the parapet, reducing the impact force on it and further reducing the possibility of damage; at the same time, the inclination angle of the photovoltaic panel body can be further adjusted through the light source tracker to increase the power generation efficiency of the photovoltaic panel body. When it rains, by further adjusting the inclination angle of the photovoltaic panel body, the collected rainwater can be conveniently transmitted to the greening water storage system through the arc-shaped water collection plate, which is convenient for rainwater collection and storage.

[0020] (4) The present invention uses a cleaning structure to fully clean the photovoltaic panel body. By cleaning the photovoltaic panel body, problems such as a decrease in power generation efficiency of the photovoltaic panel body due to long-term use can be prevented. At the same time, a serpentine-shaped cleaning pipeline is used to reduce the temperature of the photovoltaic panel body to prevent the temperature from being too high and causing malfunctions.

[0021] (5) The present invention stores the electricity generated by the photovoltaic water collection system and the collected rainwater through the greening water storage system. The greening water storage system is suspended on the parapet and will not affect the normal drainage of the building roof. At the same time, it realizes the irrigation of green plants by automatic water absorption, forming a spatial structure for energy storage, water storage and green plant planting, which can significantly reduce the temperature of the building roof and improve the livability of the building.

[0033] A green roof for a sponge city, using the following method, including the following steps; S1. Using the photovoltaic water collection structure 408 in the photovoltaic water collection system 4 to adjust the photovoltaic panel body 425.

[0034] Due to the differences in light intensity and angle in different regions, the photovoltaic water collection structure 408 of the present invention can perform real-time tracking according to light intensity and angle, making it convenient for the photovoltaic panel body 425 to adjust the tilt angle according to the light direction, thereby improving the light energy conversion efficiency of the photovoltaic panel body 425.

[0035] The photovoltaic water collection structure 408 is raised and lowered by tracking the photovoltaic bracket 424 that can be raised and lowered and folded on the chassis 404, so that each photovoltaic panel body 425 can adjust the height of the photovoltaic panel body 425 according to actual needs, and it is convenient to change the height and position of the photovoltaic panel body 425 according to the lighting time and lighting angle, thereby improving the light energy conversion efficiency of the photovoltaic panel. At the same time, when the photovoltaic panel body 425 on the roof of the building 3 is threatened by storms, strong winds, etc., the height of the photovoltaic panel body 425 is lowered, and the parapet 1 on the outer periphery of the roof of the building 3 is used to reduce the impact on the photovoltaic panel body 425, thereby ensuring the safety of the photovoltaic panel body 425; the converted electric energy of the photovoltaic panel body 425 is transmitted to the energy storage battery 209 in the energy storage platform 201 in the greening water storage system 2 for storage and use.

[0036] The photovoltaic water collection structure 408 adjusts the inclination angle of the photovoltaic panel body 425 through the light source tracking disk 427 of the light source tracker 423, and realizes the adjustment of the angle of the photovoltaic panel body 425 through multiple tracking push rods 428. The ball joint heads 430 at both ends of the tracking push rods 428 rotate in the photovoltaic ball joint seat and the light source ball joint seat 429 respectively to meet the needs of angle adjustment of the photovoltaic panel body 425; by adjusting the inclination angle of the photovoltaic panel body 425, it is convenient to improve the power generation efficiency of the photovoltaic panel body 425. When it rains, by adjusting the inclination angle of the photovoltaic panel body 425, it is also convenient to use the photovoltaic panel body 425 to collect rainwater, thereby meeting the purpose of collecting rainwater on the building roof 3.

[0037] S2. Use the tracking structure in the photovoltaic water collection system 4 to adjust the photovoltaic panel body 425.

[0038] The tracking structure can adjust the horizontal rotation angle of the photovoltaic panel body 425, and further adjust the height and tilt angle of the photovoltaic panel body 425 through the tracking regulator 409, which can further improve the application range of the photovoltaic panel body 425. The tracking regulator 409 adopts a flexible structure, which can reduce the impact force on the photovoltaic panel body 425 when impacted by gusts of wind, thereby improving the stability and safety of the photovoltaic panel body 425.

[0039] When the photovoltaic panel body 425 needs to rotate horizontally to meet the need of the photovoltaic panel body 425 to track sunlight, the tracking motor 403 drives the tracking gear ring 406 to rotate, so that the tracking chassis 404 rotates along the tracking shaft 405 in the tracking groove 410 of the building roof 3, and the tracking gear 402 moves along the tracking ring groove to ensure the rotation stability of the tracking chassis 404, thereby driving the entire photovoltaic water collection system 4 to rotate horizontally on the building roof 3, and adjusting the horizontal position of the photovoltaic panel body 425 to meet the need of the photovoltaic panel body 425 to track light.

[0040] The height and tilt angle of the photovoltaic panel body 425 are further adjusted by using the tracking regulator 409, which increases the adjustment range of the photovoltaic panel body 425 and improves the ability of the photovoltaic panel body 425 to resist sudden impacts such as gusts of wind; the tracking regulator 409 fills the boosting chamber 415 with pressurized gas through the boosting air pump 417, and the boosting gas enters each spiral airbag 422 along the boosting air pipe 413. By controlling the air intake in the spiral airbag 422, the lifting height of the spiral airbag 422 is controlled. By adjusting the lifting height of each spiral airbag 422, the tracking folding ring 416 is folded and stretched, so that the angle of the tracking base 407 changes, which can meet the adjustment requirements of the tilt angle of the photovoltaic panel body 425.

[0041] During the adjustment process of each spiral airbag 422 of the tracking adjustment member 411, the tracking telescopic rod 412 is extended and retracted, and the positioning ring 420 and the connecting ring 418 slide on the tracking telescopic rod 412. The positioning protrusion 421 can prevent the spiral airbag 422 under the tracking spring 419 from being completely flattened within a certain area restricted by the positioning ring 420 and the connecting ring 418, thereby affecting the normal use of the spiral airbag 422. The reversing exhaust valve 414 realizes the air intake and deflation of the spiral airbag 422 by reversing, which can meet the inflation and deflation requirements of the spiral airbag 422; the flexible protective shell covering the tracking spring 419 and the spiral airbag 422 can prevent the spiral airbag 422, the tracking telescopic rod 412, and the tracking spring 419 from making hard contact, thereby ensuring the stability and safety of the three during long-term use, and a smooth coating is applied on the flexible protective shell.

[0042] In addition, when the photovoltaic panel body 425 is subjected to sudden impacts such as gusts of wind, the spiral airbag 422 and the tracking spring 419 can absorb the impact force on the photovoltaic panel body 425, prevent the photovoltaic panel body 425 from being damaged, and improve the safety and stability of the photovoltaic panel body 425.

[0043] S3. Use the cleaning structure 426 in the photovoltaic water collection system 4 to clean the photovoltaic panel body 425.

[0044] After the photovoltaic panel body 425 has been working for a long time, dust and other impurities will adhere to the surface, affecting the power generation efficiency. The cleaning structure 426 is used to clean the surface of the photovoltaic panel body 425, so as to maintain the power generation efficiency of the photovoltaic panel body 425. Specifically, the photovoltaic panel body 425 generates heat during the power generation process, which increases the temperature of the photovoltaic panel body 425. The cleaning pipes serpentinely distributed on the back of the photovoltaic panel body 425 absorb the heat of the photovoltaic panel body 425, which can reduce the temperature of the photovoltaic panel body 425 and maintain the power generation efficiency of the photovoltaic panel body 425. The cleaning pipes are connected to the water tank 202. The cleaning structure 426 draws water in the cleaning pipes into the booster box 433 through the booster pump 432, and cleans the sealed bearing 443 along the hollow cleaning pipe 443. 4 flows into the hollow cleaning screw 438, and is uniformly sprayed toward the photovoltaic panel body 425 through the pressurized cleaning hole 439. The cleaning motor 442 of the pressurized cleaning member 434 drives the hollow cleaning screw 438 to rotate along the cleaning sealing bearing 444. Under the friction between the photovoltaic panel body 425 and the cleaning bristles 441 on the cleaning screw barrel 440, the cleaning screw barrel 440 cannot rotate on the photovoltaic panel body 425. Therefore, as the hollow cleaning screw 438 rotates, the cleaning screw barrel 440 rotates on the hollow cleaning screw 438, and the cleaning screw barrel 440 is engaged with the thread on the hollow cleaning screw 438, so that the cleaning screw barrel 440 moves along the hollow cleaning screw 438, thereby driving the cleaning bristles 441 to clean the wet surface of the photovoltaic panel body 425.

[0045] During the cleaning process, the traction motor 437 drives the box sleeve 436 to rotate, and the box sleeve 436 engages with the thread on the cleaning guide rail 431, so that the box sleeve 436 moves along the cleaning guide rail 431, and the box bearing 435 drives the booster box 433 to move along the cleaning guide rail 431, thereby driving the booster cleaning part 434 to move left and right along the photovoltaic panel body 425 when cleaning the photovoltaic panel body 425, and can completely clean the surface of the photovoltaic panel body 425, thereby realizing the cleaning process of the photovoltaic panel body 425.

[0046] S4. Greening and water storage of green roofs in sponge cities.

[0047] The greening water storage system 2 on the building roof 3 is used to collect rainwater and water green plants. When it rains, the raindrop sensor on the water diverter 205 detects the falling of raindrops, and the control processor controls the photovoltaic water collection structure 408 and the tracking structure to adjust, so that the lower end of the photovoltaic panel body 425 tilts toward the arc-shaped water collection plate 401, the water diverter 205 is opened, and the water diversion push rod 213 pushes the uppermost arc-shaped water diversion plate 212 away from the water storage tank 202 and the parapet 1, and the water diversion limiting ball 215 on the bottom surface of the arc-shaped water diversion plate 212 is on the top surface of the arc-shaped water diversion plate 212 under the arc-shaped water diversion plate 212. The arc-shaped water diversion plate 212 moves in the water diversion limit groove 214 on the upper part. After the water diversion limit ball 215 reaches the end of the water diversion limit groove 214, the lower arc-shaped water diversion plate 212 moves with the upper arc-shaped water diversion plate 212, thereby unfolding the arc-shaped water diversion plates 212 that are folded with each other, and then the arc-shaped water guide plate 211 is driven to move in the arc-shaped water diversion port through the lower arc-shaped water diversion plate 212, so that the uppermost arc-shaped water diversion plate 212 is close to the end of the arc-shaped water collecting plate 401, which is convenient for guiding the rainwater into the arc-shaped water collecting plate 401 along the water diverter 205 and the arc-shaped water diversion port into the water storage tank 202, thereby completing the collection of rainwater.

[0048] The rainwater in the water tank 202 is interconnected through the water pipe, and can eventually flow into each water tank 202. The rainwater flows into the flexible floating tube 207 through the filter net, so that the rainwater flows into the water diversion pipe 208. The rainwater in the water diversion pipe 208 is adsorbed into the greening soil in the greening trough 204 through the water diversion rope 203 in the water diversion sleeve, thereby realizing continuous water supply treatment for the green plants in the greening trough 204; when there is too much rainwater, the rainwater overflows the water tank 202, is filtered through the water filter net 206, and is discharged into the sewer pipe through the drainage trough 210, so as to prevent excessive rainfall from affecting the roof 3 of the building.
