Green building energy-saving roof

Abstract

This utility model relates to the field of green building technology and discloses a green building energy-saving roof. It achieves the separation of dirty water and rainwater through a structure including a diversion valve, a drain outlet, a float, and a water collection pipe. At the beginning of rainfall, the first wave of rainwater flows from the surface of the solar panel into the guide channel. Subsequently, mixed with dust and debris, it flows through the rainwater pipe into the diversion valve. Dirty water flows into the diversion valve from the rainwater pipe and is discharged through the gaps between the floats. During the middle of the rainy season, after the dirty water mixed with dust on the surface of the solar panel and inside the guide channel has been drained, clean rainwater flows into the diversion valve through the guide channel. The continuous flow of clean rainwater into the diversion valve causes the water level to rise, driving the float to the bottom of the water collection pipe. When the float reaches the lowest point of the water collection pipe, it pulls the pull rope upwards. As the rope rises, it pulls a baffle plate, which then blocks the opening of the drain outlet. Clean rainwater accumulates and flows into the water tank through the water collection pipe, effectively separating dirty water from rainwater.

Description

Technical Field

[0001] This utility model relates to the field of green building technology, and in particular to a green building energy-saving roof. Background Technology

[0002] Green buildings, throughout their entire life cycle, conserve resources, protect the environment, reduce pollution, and provide people with healthy, suitable, and efficient living spaces, maximizing the harmonious coexistence of humans and nature in high-quality architecture. Roof energy conservation mainly includes thermal insulation roofs, flat-to-slope roof conversions, ventilated roofs, green roofs (green roofs), water-storage roofs, and other new types of roofs.

[0003] In existing technologies, roof rainwater pipes accumulate dust and leaf debris during dry periods. When it rains, the first wave of rainwater washes the impurities into the collection box, clogging the subsequent filters. This requires manual dismantling and cleaning. Solar panels are usually installed on energy-saving roofs, but dust and bird droppings on the surface of the solar panels can reduce power generation efficiency by 10% to 20%. Manually climbing the roof to clean them is dangerous and laborious. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a green building energy-saving roof that features the advantages of separating dirty water from clean rainwater and spray cleaning, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a green building energy-saving roof, including a roof, solar panels uniformly distributed on the surface of the roof, guide channels on both sides of the roof, a diversion valve on one side of the bottom of the roof, a rainwater pipe fixedly connected between the guide channels and the diversion valve, a water tank located on the ground on one side of the roof, a float switch inside the water tank, a water pump located on one side of the roof located on the side of the water tank, a main sprinkler pipe located at the top center of the roof, and sprinkler heads uniformly arranged in a linear array on both sides of the main sprinkler pipe, the sprinkler heads being set at an oblique angle, and the spray angle of the sprinkler heads being parallel to the tilt angle of the roof.

[0006] The above structural design, through the coordination of the diversion valve, guide channel, and rainwater pipe, achieves the separation of water mixed with impurities from clean rainwater. The design is simple and inexpensive to maintain or replace. The interaction between the water tank, float switch, water pump, and main sprinkler pipe enables automatic cleaning of the solar panels.

[0007] Preferably, the bottom of the diversion valve is provided with a drain port, a baffle is rotatably installed at the bottom of the drain port, a ball frame is uniformly arranged in a circular shape around the bottom of the diversion valve outside the drain port, a float is provided inside the diversion valve above the ball frame, and a pull rope is fixedly connected between the float and one side of the baffle.

[0008] With the above structural setup, dirty water flows into the diversion valve through the rainwater pipe. As the dirty water outlet opens and discharges from it, rainwater continues to flow into the diversion valve, and the water level gradually rises. The rainwater then flows into the water tank through the collection pipe, achieving the effect of rainwater separation.

[0009] Preferably, a water inlet pipe is provided between the water tank and the diversion valve, a drain pipe is provided at the bottom of the water tank, and a valve body is provided at the end of the drain pipe.

[0010] With the above-described structure, when users need rainwater from the tank to wash things, they can turn the valve to allow the water inside the tank to flow out through the drain pipe.

[0011] Preferably, the float switch includes a signal device and a connecting wire. The signal device is fixedly installed on the top of the water tank on one side of the water inlet pipe. The bottom of the signal device is located inside the water tank and has a connecting wire. A level gauge is installed in the middle of the connecting wire, and a float box is fixedly connected to the bottom end of the connecting wire.

[0012] With the above-mentioned structure, when the water level inside the tank causes the float box to rise above the liquid level, the signal device will send a signal to the water pump, causing the water pump to start working.

[0013] Preferably, an input pipe is fixedly connected between the inlet of the water pump and the interior of the water tank, and an output pipe is fixedly connected between the outlet of the water pump and the inlet of the main sprinkler pipe.

[0014] With the above-described structure, the water pump draws rainwater from inside the water tank through the input pipe, and then pumps it into the main sprinkler pipe through the output pipe, causing the rainwater to be sprayed obliquely through the sprinkler heads and wash the surface of the solar panel from top to bottom.

[0015] This utility model has the following advantages: 1. This green building energy-saving roof achieves the separation of dirty water and rainwater through a structure including a diversion valve, a sewage outlet, a float, and a water collection pipe. At the beginning of rainfall, the first wave of rainwater flows from the surface of the solar panels into the guide channel. Subsequently, mixed with dust and debris, it flows through the rainwater pipe into the diversion valve. Dirty water flows into the diversion valve from the rainwater pipe and is discharged through the gaps between the floats. In the middle of the rainy season, after the dirty water mixed with dust from the surface of the solar panels and the guide channel has been drained, clean rainwater flows into the diversion valve through the guide channel. The continuous flow of clean rainwater into the diversion valve causes the water level to rise, driving the float to the lowest point of the water collection pipe. When the float reaches the lowest point of the water collection pipe, it pulls the pull rope upwards. As the rope rises, it pulls the baffle to rotate and block the opening of the sewage outlet. Clean rainwater accumulates and flows into the water tank through the water collection pipe, effectively separating dirty water from rainwater.

[0016] 2. This green building energy-saving roof achieves automatic spraying and washing of solar panels through a structure including a water tank, float switch, water pump, and sprinkler main pipe. As the water level inside the tank slowly rises, it causes the float box to float continuously. When the water tank is about to be filled with rainwater, the float box rises above the level gauge position due to the water level. At this time, the signal device sends a signal to the water pump. After the water pump starts, it draws water from the water tank through the input pipe and pumps it into the sprinkler main pipe through the output pipe. The sprinkler main pipe sprays rainwater out through the spray heads, washing the surface of the solar panels from top to bottom. After washing for a period of time, the water level inside the tank drops to the designated position, the float box descends, and the water pump shuts off. The spraying is triggered again when the water tank is filled with rainwater, thus achieving the effect of automatic spraying and washing. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4A green building energy-saving roof includes a roof 1, on which solar panels are uniformly distributed. Drainage channels 11 are provided on both sides of the roof 1. A diversion valve 2 is provided on one side of the bottom of the roof 1. A rainwater pipe 12 is fixedly connected between the drainage channels 11 and the diversion valve 2. A water tank 3 is located on the ground on one side of the roof 1. A float switch 4 is installed inside the water tank 3. A water pump 5 is located on one side of the roof 1, located on the side of the water tank 3. A sprinkler main pipe 6 is located in the middle of the top of the roof 1. Sprinkler heads 61 are uniformly arranged in a linear array on both sides of the sprinkler main pipe 6. The sprinkler heads 61 are set at an angle, and the spray angle of the sprinkler heads 61 is parallel to the tilt angle of the roof 1.

[0021] In practical applications, this device separates water mixed with impurities from clean rainwater through the cooperation of the diversion valve 2, the guide channel 11, and the rainwater pipe 12. The structure is simple and inexpensive to maintain or replace. Before rain, dust and debris accumulate inside the guide channel 11 and the rainwater pipe 12. Since the diversion valve 2 is dry, the float 24 is initially positioned at the top of the frame 23, while the baffle 22 hangs down due to gravity, keeping the drain outlet 21 open. At the beginning of the rain, the first wave of rainwater falls on the surface of the roof 1 above the solar panels and then slides down the surface into the guide channel 11. Inside, rainwater mixes with dust and debris to form dirty water. The dirty water flows into the diversion valve 2 through the rainwater pipe 12. Since the drain port 21 is open, the dirty water is discharged from the drain port 21. During the middle of the rain, after the dirty water inside the guide channel 11 and the rainwater pipe 12 is drained, the rainwater continues to flow into the diversion valve 2, and the water level gradually rises. The water level inside the diversion valve 2 causes the float ball 24 to rise. The float ball 24 pulls the baffle 22 through the pull rope 25 to rotate and block the opening of the drain port 21. After the water level causes the float ball 24 to rise a certain distance, the rainwater flows into the water tank 3 through the water collection pipe 31, achieving the effect of rainwater separation.

[0022] By setting up the cooperation between the water tank 3, float switch 4, water pump 5 and spray pipe 6, the effect of automatic cleaning of solar panels is achieved. The float switch 4 detects the water level inside the water tank 3 through the float box 44. When the water tank 3 is almost full, the float switch 4 sends a signal to the water pump 5 to start the water pump for a period of time. When the water pump 5 is working, it draws water from the water tank 3 through the input pipe 51 and then pumps it into the spray pipe 6 through the output pipe 52. The spray pipe 6 sprays water out through the spray head 61 to clean the solar panels.

[0023] Please see Figures 1-2 The bottom of the diversion valve 2 is provided with a drain port 21. A baffle 22 is rotatably installed at the bottom of the drain port 21. A ball frame 23 is evenly provided in a circular shape around the bottom of the drain port 21. A float ball 24 is provided inside the diversion valve 2 above the ball frame 23. A pull rope 25 is fixedly connected between the float ball 24 and one side of the baffle 22.

[0024] Before it rains, the float 24, lacking buoyancy, will automatically droop, and the baffle 22 will also droop due to gravity, opening the drain outlet 21. In the early stages of rain, after about half a minute to one minute, the first wave of rainwater mixes with dust and debris from the roof surface 1 and the inside of the drainage channel 11, and is discharged into the diversion valve 2 through the rainwater pipe 12. The dirty water is discharged through the drain outlet 21. In the middle of the rain, the amount of rainwater increases, and the roof surface 1 and the inside of the drainage channel 11 are cleaned. Clean rainwater enters the diversion valve 2 through the rainwater pipe 12. The inflow of water into the diversion valve 2 is greater than the outflow of water from the drain outlet 21. At this time, the water level inside the diversion valve 2 rises, causing the float 24 to float upwards. When the float 24 floats, it pulls the baffle 22 upwards through the pull rope 25, blocking the opening of the drain outlet 21, allowing clean rainwater to accumulate inside the diversion valve 2. After accumulating to a certain water level, it is discharged into the water tank 3 through the water collection pipe 31.

[0025] Please see Figures 1-3 A water inlet pipe 31 is provided between the water tank 3 and the diversion valve 2, and a drain pipe 32 is provided at the bottom of the water tank 3. A valve body 33 is provided at the end of the drain pipe 32.

[0026] The water tank 3 actually serves to store rainwater. When the user needs the rainwater in the water tank 3 to wash things, the water inside the water tank 3 can be drained out through the drain pipe 32 by turning the valve body 33.

[0027] Please see Figures 1-3 The float switch 4 includes a signal device 41 and a connecting line 42. The signal device 41 is fixedly installed on the top of the water tank 3 on one side of the water inlet pipe 31. The bottom of the signal device 41 is located inside the water tank 3 and the connecting line 42 is provided. A level gauge 43 is provided in the middle of the connecting line 42 and a float box 44 is fixedly connected to the bottom end of the connecting line 42.

[0028] The accumulation of rainwater inside the water tank 3 can cause the float box 44 to float upwards. When the water level inside the water tank 3 causes the float box 44 to float upwards above the level gauge 43, the signal device 41 will send a signal to the water pump 5 to start the water pump 5.

[0029] Please see Figures 1-4 The water pump 5 is fixedly connected to the water tank 3 by an input pipe 51, and the water pump 5 is fixedly connected to the sprinkler main pipe 6 by an output pipe 52. The power supply for the water pump 5 comes from a solar panel.

[0030] When the water pump 5 receives the signal from the signaler 41, it can start working for a short time. The water pump 5 draws rainwater from the water tank 3 through the input pipe 51, and then pumps it into the sprinkler main pipe 6 through the output pipe 52, so that the rainwater is sprayed out obliquely through the sprinkler head 61 and washes the surface of the solar panel from top to bottom. After the water level in the water tank 3 drops a certain distance, the float box 44 drops and the water pump 5 stops working.

[0031] Working principle: Before it rains, there is no water inside the diversion valve 2. The float ball 24 falls on the top of the ball frame 23, and the baffle 22 hangs down naturally by gravity, which opens the opening of the sewage outlet 21. Dust and debris accumulate on the surface of the solar panel and inside the guide channel 11. On rainy days, at the beginning of the rain, the first wave of rainwater flows from the surface of the solar panel into the interior of the guide channel 11. Then, mixed with dust and debris, it flows through the rainwater pipe 12 into the interior of the diversion valve 2. After the dirty water flows into the interior of the diversion valve 2 from the rainwater pipe 12, it enters the drain port 21 through the gap between the ball brackets 23 and is discharged into the interior of the diversion valve 2. Although the water level rises slowly, it is not enough to make the float completely float. During the middle of the rainy season, after the dirty water mixed with dust on the surface of the solar panel and inside the diversion channel 11 is drained, clean rainwater flows into the diversion valve 2 through the diversion channel 11. The clean rainwater continues to flow into the diversion valve 2, causing the water level to drive the float ball 24 to rise. When the water level causes the float ball 24 to float to the lowest surface of the water collection pipe 31, the float ball 24 rises and pulls the pull rope 25 to rise synchronously. When the pull rope 25 rises, it pulls the baffle 22 to rotate and block the opening of the dirty outlet 21. The clean rainwater accumulates and flows into the water tank 3 through the water collection pipe 31. Rainwater flows into the water tank 3 through the collection pipe 31 and accumulates inside. As the water level inside the water tank 3 slowly rises, it causes the float box 44 to float continuously. When the water tank 3 is about to be filled with rainwater, the float box 44 rises above the level gauge 43 due to the water level. At this time, the signal device 41 sends a signal to the water pump 5. After the water pump 5 starts, it draws water from the water tank 3 through the input pipe 51 and pumps it into the sprinkler main pipe 6 through the output pipe 52. The sprinkler main pipe 6 sprays rainwater out through the sprinkler head 61, washing the surface of the solar panel from top to bottom. After washing for a period of time, the water level inside the water tank 3 drops to the designated position, the float box 44 descends, and the water pump 5 shuts off. The sprinkler system will be triggered again when the water tank 3 is filled with rainwater.
