Description

Technical Field

[0001] The present invention belongs to the technical field of roof mechanisms, and particularly relates to a green building energy-saving roof structure. Background Art

[0002] A green building energy-saving roof refers to a special roof design adopted in green buildings, aiming to achieve energy-saving effects through various technical means; by integrating building photovoltaics, it can meet the daily electricity demand and improve the ecological benefits of green buildings.

[0003] For example, in an energy-saving and environmental protection type green building device with the existing publication number CN217998364U, multiple solar panels are symmetrically distributed on both sides of the roof. The solar panels on each side are evenly arranged. A cleaning plate that can slide up and down along the surface of the solar panel is provided on each solar panel, and a cleaning cotton for cleaning the surface of the solar panel is provided at the bottom of the cleaning plate.

[0004] In the above method, photovoltaic panels are directly laid on the roof. In case of bad weather, such as hail and strong wind weather, sundries carried by hail or strong wind will impact the photovoltaic panels, causing damage to the photovoltaic panels and affecting the service life of the photovoltaic panels. Moreover, after snowfall, ice layers are likely to appear on the photovoltaic panels, affecting the working efficiency of the photovoltaic panels. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a green building energy-saving roof structure, aiming to solve the problem that in case of bad weather, sundries carried by hail or strong wind will impact the photovoltaic panels, causing damage to the photovoltaic panels.

[0006] The present invention is implemented as follows. A green building energy-saving roof structure includes a roof, and further includes: a plurality of cylindrical grooves arranged along the length direction at the upper end of the roof. Mounting frames are fixed in the plurality of cylindrical grooves, and a plurality of photovoltaic panels are installed at the upper ends of the mounting frames; a plurality of protective cylinders are rotatably connected in the plurality of cylindrical grooves. An opening is provided on the side wall of the protective cylinder. A cavity is provided in the middle of the roof, and one end of the protective cylinder extends into the cavity; a driving component is provided in the cavity. The driving component is used to drive the plurality of protective cylinders to rotate synchronously. When the opening of the protective cylinder rotates upward, the upper end of the roof, the upper end of the mounting frame, the upper end of the photovoltaic panel, and the protective cylinder form a plane. When the opening of the protective cylinder rotates downward, the photovoltaic panel is located inside the protective cylinder, and a diversion groove is formed between every two protective cylinders.

[0007] In a further technical solution, one end of the mounting frame is fixed in the cylindrical groove, the other end of the mounting frame is fixed with a fixed shaft, a fixed rod is fixed on the fixed shaft, and the end of the fixed rod is fixed in the cavity.

[0008] Further technical solution: The driving component includes an installation cylinder. One end of the protective cylinder extending into the cavity is closed, and the installation cylinder is fixed to one end of the protective cylinder extending into the cavity. The fixed shaft penetrates through the protective cylinder and the installation cylinder, and the fixed shaft is rotatably connected within the installation cylinder. A gear is fixed on the installation cylinder. A guiding groove is provided at the bottom of the cavity. A sliding frame is slidably connected to the guiding groove. A rack is fixed on the sliding frame. The rack meshes with the gear. A moving module is arranged within the cavity, and the moving module is used to drive the sliding frame to move within the guiding groove.

[0009] Further technical solution: The moving module includes a lead screw rotatably connected to one end of the cavity. The lead screw is threadedly connected to the sliding frame. A first motor is fixed to one end of the roof, and the rotating end of the first motor is connected to the lead screw.

[0010] Further technical solution: A fresh air inlet is provided at the bottom of the cavity. An avoidance groove cooperating with the fresh air inlet is provided on the sliding frame. A through hole is provided at one end of the protective cylinder located within the cavity. A first filter screen is installed on the through hole. When the opening of the protective cylinder rotates upwards, the protective cylinder and the installation frame form a ventilation pipe, and the ventilation pipe communicates with the cavity through the through hole.

[0011] Further technical solution: A air supply component is provided at the other end of the roof. The air supply component includes an air inlet provided at the other end of the roof, and a second motor fixed to the other end of the roof. The rotating end of the second motor is connected to a driving shaft. The driving shaft extends into the cavity, and blades are fixed on the driving shaft.

[0012] Further technical solution: An arc-shaped heating plate is embedded on the inner wall of the protective cylinder. When the opening of the protective cylinder rotates downwards, the installation frame and the protective cylinder form a heating space.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In severe weather such as strong winds, hailstorms, and freezing rains, the driving component drives multiple protective cylinders to rotate synchronously. The opening of the protective cylinder rotates downwards, and the photovoltaic panel is located within the protective cylinder. Thus, the protective cylinder protects the photovoltaic panel from being eroded by rainwater and impacted by foreign objects, preventing damage.

[0015] 2. A diversion groove is formed between every two protective cylinders. The diversion groove can guide and drain the rainwater on the roof, improving the drainage efficiency of the roof, avoiding water accumulation on the roof, thereby preventing water leakage and roof damage. By draining water in a timely manner, the diversion groove protects the structure of the roof and the house, preventing structural damage caused by water accumulation.

[0016] 3. When the opening of the protective cylinder rotates upward, the mounting frame and the protective cylinder form a fresh air passage. External air enters the fresh air passage, passes through the through holes and enters the cavity. The air in the cavity enters the room through the avoidance groove and the fresh air outlet, thereby promoting indoor air circulation and supplying fresh air to the room.

[0017] 4. When the external wind force is small or there is no wind, the air supply component sends external air into the cavity from the air inlet, and the filtered air enters the room through the avoidance groove and the fresh air outlet, thereby promoting indoor air circulation and supplying fresh air to the room.

[0018] 5. By rotating the protective cylinder, the mounting frame scrapes off dust and other impurities on the first filter screen, thereby cleaning the first filter screen and improving the quality of fresh air in the room. When the opening of the protective cylinder rotates downward, the air in the cavity passes through the first filter screen and the through holes and enters the cleaning channel, and then blows away the dust and other impurities on the photovoltaic panel by means of wind, thereby improving the working efficiency of the photovoltaic panel. Moreover, when the air passes through the first filter screen, the first filter screen is backwashed.

[0019] 6. When there is snow or ice on the photovoltaic panel, rotate the protective cylinder so that the opening of the protective cylinder faces downward. The mounting frame and the protective cylinder form a heating space, which can gather the heat of the heating plate and reduce the heat dissipation, thereby saving energy and increasing the melting speed of the ice and snow on the photovoltaic panel.

When the opening 106 of the protective cylinder 105 rotates upwards, the upper end of the roof 101, the upper end of the mounting frame 103, the upper end of the photovoltaic panel and the protective cylinder 105 form a plane. When the opening 106 of the protective cylinder 105 rotates downwards, the photovoltaic panel is located inside the protective cylinder 105, and a diversion groove is formed between every two protective cylinders 105.

[0040] In the embodiment of the present invention, in the initial state, the opening 106 of the protective cylinder 105 rotates upwards, the photovoltaic panel is unobstructed, and the photovoltaic panel is in a working state. At this time, the upper end of the roof 101, the upper end of the mounting frame 103, the upper end of the photovoltaic panel and the protective cylinder 105 form a plane, thereby reducing the formation of angles for dirt accumulation. When the wind blows over the roof, the dust and impurities on the roof can be smoothly blown away, reducing the accumulation of dust and other impurities at the upper end of the roof 101, making the roof 101 more beautiful and clean, unobstructed, and improving the working efficiency of the photovoltaic panel; in bad weather such as strong wind, hail, and freezing rain, the driving component 2 drives the plurality of protective cylinders 105 to rotate synchronously, and the opening 106 of the protective cylinder 105 rotates downwards, and the photovoltaic panel is located inside the protective cylinder 105. Furthermore, the protective cylinder 105 protects the photovoltaic panel from being eroded by rainwater and impacted by foreign objects, resulting in damage. And a diversion groove is formed between every two protective cylinders 105, and the diversion groove can guide and discharge the rainwater on the roof 101, improving the drainage efficiency of the roof 101, avoiding water accumulation on the roof 101, thereby preventing water leakage and damage to the roof 101. By draining water in time, the diversion groove protects the structure of the roof 101 and the house, preventing structural damage caused by water accumulation.

[0041] As Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 12 and Figure 13As shown, as a preferred embodiment of the present invention, one end of the mounting frame 103 is fixed in the cylindrical groove 102, the other end of the mounting frame 103 is fixed with a fixed shaft 108, a fixed rod 109 is fixed on the fixed shaft 108, and the end of the fixed rod 109 is fixed in the cavity 107.

[0042] In the embodiment of the present invention, both ends of the mounting frame 103 are fixed, so that there is a gap between the side wall of the mounting frame 103 and the cylindrical groove 102, leaving space for the installation and rotation of the protective cylinder 105.

[0043] As Figures 1 - 10 As shown, as a preferred embodiment of the present invention, the drive assembly 2 includes an installation cylinder 201. One end of the protective cylinder 105 extending into the cavity 107 is closed, and the installation cylinder 201 is fixed to one end of the protective cylinder 105 extending into the cavity 107. The fixed shaft 108 passes through the protective cylinder 105 and the installation cylinder 201, and the fixed shaft 108 is rotatably connected in the installation cylinder 201. A gear 202 is fixed on the installation cylinder 201. A guide groove 203 is provided at the bottom of the cavity 107. A sliding frame 204 is slidably connected to the guide groove 203. A rack 205 is fixed on the sliding frame 204. The rack 205 meshes with the gear 202. A moving module is provided in the cavity 107. The moving module is used to drive the sliding frame 204 to move in the guide groove 203. The moving module includes a lead screw 206 rotatably connected to one end of the cavity 107. The lead screw 206 is threadedly connected to the sliding frame 204. One end of the roof 101 is fixed with a motor 207. The rotating end of the motor 207 is connected to the lead screw 206.

[0044] In the embodiment of the present invention, the motor 207 drives the lead screw 206 to rotate. Under the guiding action of the guide groove 203, the lead screw 206 drives the sliding frame 204 to move through threaded transmission. The sliding frame 204 drives the rack 205 to move. The rack 205 drives the gear 202 to rotate. The gear 202 drives the installation cylinder 201 to rotate. The installation cylinder 201 drives the protective cylinder 105 to rotate.

[0045] As Figures 1 - 12 As shown, as a preferred embodiment of the present invention, a fresh air inlet 303 is provided at the bottom of the cavity 107. An avoidance groove 302 cooperating with the fresh air inlet 303 is provided on the sliding frame 204. A through hole 301 is provided at one end of the protective cylinder 105 located in the cavity 107. A first filter screen is installed on the through hole 301. When the opening 106 of the protective cylinder 105 rotates upwards, the protective cylinder 105 and the mounting frame 103 form a ventilation pipe, and the ventilation pipe is communicated with the cavity 107 through the through hole 301.

[0046] In the embodiment of the present invention, the protective cylinder 105 is in the position of Figure 10In the [specific state], the mounting bracket 103 and the protective cylinder 105 form a fresh air passage. External air enters the fresh air passage, passes through the through-hole 301 and enters the cavity 107. The first filter screens the external air. The air in the cavity 107 enters the room through the avoidance groove 302 and the fresh air outlet 303, thereby promoting the circulation of indoor air and supplying fresh air to the room. When the protective cylinder 105 rotates, the protective cylinder 105 drives the first filter to rotate. The first filter rotates relative to the mounting bracket 103, and the mounting bracket 103 scrapes off dust and other impurities on the first filter, thereby cleaning the first filter and improving the quality of fresh air in the room.

[0047] In severe weather such as strong winds and heavy rains, the first motor 207 drives the lead screw 206 to rotate. Under the guiding action of the guiding groove 203, the lead screw 206 drives the sliding frame 204 to move through screw drive. The sliding frame 204 drives the rack 205 to move, the rack 205 drives the gear 202 to rotate the rod, the gear 202 drives the mounting cylinder 201 to rotate, and the mounting cylinder 201 drives the protective cylinder 105 to rotate. When the protective cylinder 105 rotates and protects the photovoltaic panel, after the sliding frame 204 moves, the avoidance groove 302 on the sliding frame 204 is misaligned with the fresh air outlet 303, thereby blocking the fresh air outlet 303 and playing an active closing role for the fresh air outlet 303 to prevent external moisture from entering the room through the fresh air outlet 303.

[0048] As Figures 1 - 12 shown, as a preferred embodiment of the present invention, the other end of the roof 101 is provided with a air supply component 4. The air supply component 4 includes an air inlet 401 provided at the other end of the roof 101, and a second motor 402 fixed to the other end of the roof 101. The rotating end of the second motor 402 is connected to a drive shaft 403. The drive shaft 403 extends into the cavity 107. A blade 404 is fixed on the drive shaft 403. A second filter is installed on the air inlet 401.

[0049] In the embodiment of the present invention, when the external wind force is small or there is no wind, the second motor 402 drives the drive shaft 403 to rotate, the drive shaft 403 drives the blade 404 to rotate. External air is filtered by the second filter and enters the cavity 107 from the air inlet 401. The filtered air enters the room through the avoidance groove 302 and the fresh air outlet 303, thereby promoting the circulation of indoor air and supplying fresh air to the room.

[0050] The protective cylinder 105 rotates to Figure 11In the [specific state], the avoidance groove 302 is misaligned with the fresh air inlet 303, thereby blocking the fresh air inlet 303. The mounting frame 103 and the protective cylinder 105 form a cleaning channel. At this time, the air in the cavity 107 passes through the first filter screen and the through hole 301 and enters the cleaning channel, and then cleans the photovoltaic panel by means of wind force, thereby blowing away dust and other impurities on the photovoltaic panel, improving the working efficiency of the photovoltaic panel. Moreover, when the air passes through the first filter screen, it performs backwashing on the first filter screen, achieving a cleaning effect on the first filter screen, thereby improving the filtering effect of the first filter screen, preventing impurities from blocking the first filter screen, and improving the quality of indoor fresh air.

[0051] As Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 11 , Figure 12 and Figure 13 shown, as a preferred embodiment of the present invention, an arc-shaped heating plate 104 is embedded on the inner wall of the protective cylinder 105. When the opening 106 of the protective cylinder 105 rotates downward, the mounting frame 103 and the protective cylinder 105 form a heating space.

[0052] In the embodiment of the present invention, when the protective cylinder 105 is in the Figure 10 state and there is snow or ice on the protective cylinder 105, the heating plate 104 is powered on to generate heat, melting the ice and snow on the protective cylinder 105, accelerating the melting of the ice and snow, and then quickly removing the ice and snow on the protective cylinder 105, avoiding affecting the operation of the photovoltaic panel due to the long melting time of the ice and snow; when the protective cylinder 105 is in the Figure 11 state and there is snow or ice on the photovoltaic panel, rotate the protective cylinder 105 so that the opening 106 of the protective cylinder 105 faces downward. The mounting frame 103 and the protective cylinder 105 form a heating space, and the heating plate 104 is powered on to generate heat, thereby melting the ice and snow in the heating space. The heating space can aggregate the heat of the heating plate 104, reduce the diffusion of heat, thereby saving energy, increasing the melting speed of the ice and snow on the photovoltaic panel, and avoiding affecting the operation of the photovoltaic panel due to the long melting time of the ice and snow.

[0053] In the above embodiment of the present invention, a green building energy-saving roof structure is provided. In the initial state, the opening 106 of the protective cylinder 105 rotates upward, the photovoltaic panel is unobstructed, and the photovoltaic panel is in a working state. At this time, the upper end of the roof 101, the upper end of the mounting frame 103, the upper end of the photovoltaic panel, and the protective cylinder 105 form a plane, thereby reducing the formation of dirt-trapping angles, reducing the accumulation of dust and other impurities on the upper end of the roof 101, and making the roof 101 more beautiful and tidy;

[0054] At this time, the mounting bracket 103 and the protective cylinder 105 form a fresh air passage. External air enters the fresh air passage, passes through the through hole 301 and enters the cavity 107. The first filter filters the external air. The air in the cavity 107 enters the room through the avoidance groove 302 and the fresh air outlet 303, thereby promoting the circulation of indoor air and supplying fresh air to the room. When the external wind force is small or there is no wind, the second motor 402 drives the drive shaft 403 to rotate, the drive shaft 403 drives the blades 404 to rotate. After the external air is filtered by the second filter, it enters the cavity 107 from the air inlet 401. The filtered air enters the room through the avoidance groove 302 and the fresh air outlet 303, thereby promoting the circulation of indoor air and supplying fresh air to the room;

[0055] In case of bad weather such as strong wind, hail and freezing rain, the first motor 207 drives the lead screw 206 to rotate. Under the guiding action of the guiding groove 203, the lead screw 206 drives the sliding frame 204 to move through screw transmission. The sliding frame 204 drives the rack 205 to move, the rack 205 drives the gear 202 to rotate the rod, the gear 202 drives the mounting cylinder 201 to rotate, the mounting cylinder 201 drives the protective cylinder 105 to rotate, and the opening 106 of the protective cylinder 105 rotates downward. The photovoltaic panel is located in the protective cylinder 105. Furthermore, the protective cylinder 105 protects the photovoltaic panel from being eroded by rainwater and impacted by foreign objects, so as to avoid damage. And a diversion groove is formed between every two protective cylinders 105. The diversion groove can guide and discharge the rainwater on the roof 101, improve the drainage efficiency of the roof 101, avoid water accumulation on the roof 101, thereby preventing water leakage and damage to the roof 101. By draining water in time, the diversion groove protects the structure of the roof 101 and the house, and prevents structural damage caused by water accumulation;

[0056] The avoidance groove 302 is misaligned with the fresh air outlet 303, thereby blocking the fresh air outlet 303. The mounting bracket 103 and the protective cylinder 105 form a cleaning passage. At this time, the air in the cavity 107 passes through the first filter screen and the through hole 301 and enters the cleaning passage, and then cleans the photovoltaic panel by means of wind force, thereby blowing away dust and other impurities on the photovoltaic panel, thus improving the working efficiency of the photovoltaic panel. And when the air passes through the first filter screen, it backwashes the first filter screen, achieving the cleaning effect on the first filter screen, thereby improving the filtering effect of the first filter screen, avoiding impurity blockage of the first filter screen, and improving the quality of fresh air in the room.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
