Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic roofs, in particular to a building photovoltaic roof structure. Background Art

[0002] Building photovoltaic roof is a new concept of applying solar power generation. Simply put, it is to install solar photovoltaic modules on the roof of the building to provide electricity. It has the function of shading and heat insulation for the building. It can not only reduce the indoor temperature of the building, but also use photovoltaic modules to provide electricity for the building, which has green, environmentally friendly and energy-saving effects.

[0003] When the existing building photovoltaic roof is in use, since the photovoltaic panels are directly installed on the roof, dust, fallen leaves and other debris are easily attached to its surface. Over time, the debris will accumulate more and more. If it is not cleaned in time, the dust will eventually cover the surface of the photovoltaic panel, reducing the lighting effect of the photovoltaic panel and greatly reducing the power generation efficiency of the photovoltaic panel. To this end, we propose a building photovoltaic roof structure to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 The invention discloses a photovoltaic roof structure for a building, comprising a roof body 1, a photovoltaic panel 2 is installed on the top of the roof body 1, a U-shaped frame 3 is provided on the top of the roof body 1, and a motor 4 is installed on one side of the U-shaped frame 3, the output end of the motor 4 passes through the inner wall of the U-shaped frame 3 and is connected with a threaded rod 5, and the end of the threaded rod 5 is connected to the inner wall of the U-shaped frame 3 through a bearing, the motor 4 can be powered by the photovoltaic panel 2, and the motor 4 can rotate forward and reverse, thereby driving the reciprocating movement of the scraper 9, and the motor 4 can be remotely controlled by the staff through a remote control, and its specific working principle is an existing mature technology, which will not be described in detail here, a threaded sleeve 6 is provided on the outer side of the threaded rod 5, and the two sides of the threaded sleeve 6 are connected to the positioning frame 8 through a connecting rod 7, and a scraper 9 is provided below the positioning frame 8, and the bottom end of the scraper 9 is set to be a rubber material, and is in contact with the upper surface of the photovoltaic panel 2, so that the cleaning operation of the photovoltaic panel 2 can be realized during the movement of the scraper 9.

[0023] Further, see Figure 3 It can be known that the inner wall of the U-shaped frame 3 is connected to a guide rod 11, and the outer side of the guide rod 11 is sleeved with a moving block 10, and the side of the moving block 10 is fixedly connected to the threaded sleeve 6. When in use, the threaded sleeve 6 can be guided by the mutual cooperation of the guide rod 11 and the moving block 10, which can effectively reverse the idling of the threaded sleeve 6.

[0024] Further, see Figure 2 and Figure 3 It can be known that the bottom end of the U-shaped frame 3 is symmetrically connected with a fixing plate 12, and the side of the fixing plate 12 close to each other is abutted against the roof body 1, and the inside of the fixing plate 12 is connected to the roof body 1 through bolts. When in use, the U-shaped frame 3 can be fixed to the position of the roof body 1 through the cooperation of the fixing plate 12 and the bolts, and when the photovoltaic components need to be inspected, the U-shaped frame 3 can be removed together with the scraper 9.

[0025] Further, see Figure 2It can be known that the inner wall of the top of the U-shaped frame 3 is connected to a protective plate 13, and the protective plate 13 is set to an arc structure. Through the setting of the protective plate 13, the threaded rod 5 can be protected to effectively prevent the threaded sleeve 6 from getting stuck during the movement. Since the protective plate 13 is set to an arc shape, the debris can be guided to the photovoltaic panel 2 and scraped away by the scraper 9, which can prevent the debris from accumulating on the top of the protective plate 13.

[0026] Further, see Figure 3 and Figure 4 It can be known that the positioning frame 8 is configured as a U-shaped structure. The positioning frame 8 configured with a U-shaped structure can facilitate the subsequent connection and fixation between it and the scraper 9. Limit blocks 17 are symmetrically inserted at both ends of the positioning frame 8, and a pulling bar 16 is connected to the side where the limit blocks 17 are away from each other. The pulling bar 16 is configured as a Z-shaped structure. The pulling bar 16 configured with a Z-shaped structure can facilitate the staff to push the two groups of pulling bars 16 together. The side where the limit blocks 17 are close to each other extends in the scraper 9, and positioning grooves compatible with the limit blocks 17 are symmetrically provided on both sides of the scraper 9. During use, through the cooperation between the pull bar 16 and the limit block 17, the staff can quickly remove the damaged scraper 9 from the inner side of the positioning frame 8.

[0027] Further, see Figure 4 It can be known that the inner side of the pull bar 16 is symmetrically connected with a spring 15, a groove is opened on the inner wall of the positioning frame 8 at a position corresponding to the spring 15, and the inner wall of the groove is connected to the other end of the spring 15. Through the setting of the groove and the spring 15, the tightness of the limit block 17 in the positioning groove inside the scraper 9 can be effectively guaranteed.

[0028] Further, see Figure 3 and Figure 4 It can be known that the outer side of the scraper 9 is symmetrically connected with a positioning block 14, and the interior of the positioning frame 8 is provided with a positioning groove compatible with the positioning block 14. When installing a new scraper 9, the staff can align the positioning block 14 connected to its side with the positioning groove opened inside the positioning frame 8. Through the mutual cooperation of the two, the preliminary connection between the positioning frame 8 and the scraper 9 can be completed, which can facilitate the staff to use the limit block 17 to connect and fix the scraper 9 later.

[0029] Working principle: When the utility model is used, the staff can first install the photovoltaic panel 2 and other photovoltaic components on the roof body 1, then place the U-shaped frame 3 at the center of the top of the roof body 1, and insert the bolts into the reserved holes opened inside the two sets of fixing plates 12 in sequence, and then use an electric drill to drive the bolts into the side walls of the roof body 1, so as to achieve the installation of the U-shaped frame 3. After using it for a period of time, the staff can remotely start the motor 4, so that it drives the rotation of the threaded rod 5, and then the threaded sleeve 6 can be threadedly matched with the threaded rod 5, so that the threaded sleeve 6 drives the movement of the two sets of connecting rods 7 and the positioning frame 8, and cooperates with the scraper 9 set under the positioning frame 8 to scrape off the debris attached to the photovoltaic panel 2;

[0030] When the scraper 9 is deformed and damaged, the staff can climb onto the roof body 1 using tools such as ladders, and then pull the two sets of pulling bars 16 set on the upper side of the positioning frame 8, thereby driving the two sets of limiting blocks 17 to move away from each other and pull them out from the inside of the scraper 9. Then the staff can translate the scraper 9, so as to remove it from the inner side of the positioning frame 8 for replacement. Through the mutual cooperation of the pulling bar 16 and the limiting block 17, the replacement efficiency of the scraper 9 can be effectively improved. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.
