Description

Technology area

[0001] The invention relates to solar energy, in particular to the field of solar module mounts. State of the art

[0002] Numerous devices are known for attaching solar modules to pitched roofs. An analogue of the proposed invention is the device described on the website http: / / www.chikosolar.com.cn.product-detail / 7-solar-rail-system.html, which uses a system of rails and anchors to attach the solar module. This analogue has a similar feature to the claimed invention—such a mounting system can be used on all types of pitched roofs, but it has disadvantages related to the need to drill holes in the roof. Another analogue is the device described on the website https: / / www.sunballast.it / en, which includes weights to prevent the solar modules from shifting.This analogue has the same function as the claimed invention—no need for holes in the roof—but it requires additional weighting of the structure. A prototype of the proposed invention is the device described on the website page https: / / www.artsignenergy.com / best-non-penetrating-solar-panel-roofmounting-systems_p172.html, in which the solar panel is mounted on folds located longitudinally along the roof slope. This prototype has the same function—no need for holes in the roof—as in the claimed invention. However, it has disadvantages, since the entire load of the solar panel mounting system is absorbed by the fold, which has a low load-bearing capacity, and its use is only possible on folded roofs. Disclosure of the invention

[0003] The aim of the present invention is to create a universal system for attaching solar modules to roofs with different types of covering, which does not require the use of weights or drilling holes in the roofs.

[0004] The technical result of the implementation of this invention is that when installing a solar module mounting system on any type of roof, no holes need to be drilled into the roof and no weights need to be installed.

[0005] Another object of the claimed invention is to reduce the labor required to install the SCSP on the roof by using lifting mechanisms with minimal use of manual labor.

[0006] Another technical result is the possibility of creating such a SCSP that allows the entire internal installation of the SCSP on the ground under factory conditions and installation on the roof in assembled state using lifting mechanisms with minimal use of manual labor.

[0007] A further object of the claimed invention is to provide an effective protection for solar modules against hail, snow and ice, with the possibility of cleaning both the solar modules and the protection itself from precipitation, dust and dirt without manual work.

[0008] Another technical result is the possibility of creating a protection system and cleaning systems, the installation of which, due to their complexity, is best carried out on site under factory conditions.

[0009] Solar roof mounting systems, also referred to as SCPS, typically consist of several main components: - Weights that support the load of the solar module mounting system and remain motionless due to their mass and the frictional force on the roof surface; - an anchor attached to the weight or supporting elements of the roof through an opening in the roofing material; - a curved plate attached to this anchor; - a support rail attached to a curved plate or anchor; - brackets attached to these support rails; - Solar modules on support rails or brackets.

[0010] The tasks solved by installing the SCSP are limited to power generation. To ensure uninterrupted power supply, it is necessary to ensure reliable mounting of the solar modules, prevent their detachment due to wind and snow, and provide for the possibility of maintenance, protection against hail, removal of dirt, snow, ice, dust, and bird droppings, as well as the repair and replacement of damaged solar modules.

[0011] The problem solved by this invention is to create a mounting system for solar modules that can solve such problems without having to drill holes in the roof.

[0012] This problem is solved by arranging a counterweight beam 6 on the roof slope 1, which is connected to a support beam 3 located on the other roof slope 1. If necessary, the support beam 3 and the counterweight beam 6 can be equipped with supports 2.

[0013] The feature of using a counterweight beam 6, located on the other side of the roof 1 and connected to the support beam 3, is a necessary element of the invention, since it is this new technical solution that enables an inventive step - balancing the weight of the support beam 3 and all parts connected to it, thereby generating the necessary clamping force, which was previously achieved by using anchors mounted through openings in the roof.

[0014] This feature allows, firstly, that no openings have to be made in the roof, secondly, that this construction can be used on any type of roof with different coverings, thirdly, that the labor costs for installing the solar modules 5 are reduced, fourthly, that there is the possibility of installing protective segments such as blinds and mechanisms for their movement, fifthly, that a mechanism for cleaning the solar modules can be installed on the movable protective segments, for example a brush with a cleaning solution, and sixthly, that a scraper is installed to clear the blind segments of snow and ice as these segments move.

[0015] The features specified in the independent claims characterize particular methods for implementing the proposed invention. The use of supports 2 allows the load of the SCSP to be concentrated at the locations of the load-bearing elements of the roof (above the purlins and rafters). The use of elastic material in the support 2 or the beams 3 and 6 allows for an even distribution of the load from the SCSP across the roof surface 1. Fastening the counterweight beam 6 and / or the support beam 3 to the underside of the roof overhang 1 using clamps 12 allows for an increase in their pressing force on the roof 1. The use of a hinged fastening 7 allows for the compensation of angle differences between different roof slopes 1. The installation of the declared SCSP devices pre-assembled on the ground using lifting mechanisms allows for a reduction in labor costs for the construction of a solar power plant.By using the blind segments 8, the solar modules 5 can be protected from hail, snow, and dirt. The solar modules 5 can be cleaned using a paper clip-shaped cleaning mechanism 10. Using a scraper 10, the blind segments 8 can be cleaned and freed of ice and snow. By using a previously unknown arrangement of blind segments 8 below and above the solar modules 5, it is possible to reduce the dimensions of the SCSP structure and eliminate the need for a separate blind drum 9 for supporting the blind segments 8 in the open position. Short description of the drawings In Fig. 1 shows an embodiment of the invention with a rigid connection of the support beam 3 and the counterweight beam 6 In Fig. Figure 2 shows a mounting system for solar modules mounted on a roof 1, which consists of a support 2 to which a support beam 3 is attached, a bracket 4, a solar module 5, a counterweight beam 6, a hinge bracket 7, blinds 8, blind shafts 9, a wiper 10, a step 11 and a handle 12. In Fig. Figure 3 shows the position of the proposed device in installation position above the roof 1. In Fig. Figure 4 shows the position of the proposed device on a pitched roof 1.

[0016] In the present invention, the following designations of the main elements of the design are used: 1 roof 2 Support 3 supporting beam bracket 4 5 solar modules 6 counterweight carriers 7 Folding bracket 8 blind segments 9 Blind shaft 10 scrapers 11 Solar module cleaning mechanism 12 Recording 13 Hooks of the lifting device 14 loop Implementation of the invention

[0017] The claimed system can be realized in the form of at least one support beam 3 resting on at least one column 2 located on one of the roof slopes 1 and having brackets 4 if necessary, a solar panel 5, a counterweight beam 6 connected to another column 2 located on another roof slope 1, these beams 3 and 6 being rigidly connected to each other or by an articulated bracket 7.

[0018] Since the counterweight beam 6 is located on the other side of the roof 1, its weight, through the rigid or articulated attachment 7, balances the weight of the support beam 3 with the supports 2, brackets 4 and solar modules 5 attached to it, and therefore the claimed device does not require the use of openings in the roof.

[0019] Within the support 3 or between two supports 3, interconnected blind segments 8 are arranged, which move under the influence of blind shafts 9. The specific design of the connection and automatic movement of the blind segments 8, the use of an electric drive, automation, and telemechanics for this purpose, as well as the design of the blind shafts 9 are known to the person skilled in the art and are not considered in the context of this invention.

[0020] The mounting system for solar modules works as follows: The weight of the support beam 3, the support 2, the brackets 4 and the solar modules 5, when interacting with a roof slope 1, is transferred via a rigid connection or articulated connection 7 to the counterweight beam 6, which rests on the other roof slope 1 via the support 1 and thereby prevents the support beam 3 with all parts attached to it from sliding down the roof slope 1.

[0021] If necessary, the counterweight beam 6 and / or the support beam 3 can be fastened with clamps 12 to the underside of the overhang of the roof slopes 1, thereby providing additional fastening of the beams 3 and 6 to the roof 1.

[0022] Due to the possibility of using handles 12, which are anchored to the lower roof overhang and / or to other supporting structures, including the ground, such an SCSP can be fixed on flat roofs.

[0023] A mechanism known from the prior art for moving the blind segments 8 can be attached to the support beam 3, namely in the form of a blind shaft 9 with a bearing unit for the blind segments 8 or in the form of two blind shafts 9 which move the blind segments 8 from a closed position (above the solar panels 5) to an open position (below the solar panels 5).

[0024] A scraper 10 can be attached to one of the shafts of the blinds 9, which scrapes snow off the blinds 8 as they move.

[0025] In one embodiment of the claimed invention, solar modules and / or brackets and / or blind segments with blind shaft and / or wiper are also arranged on a counterweight support, which is relevant when the roof ridge is located in a direction close to the north = south line.

[0026] In a further embodiment of the claimed invention, the support beam 3 on which the solar modules are located and / or consoles and / or blind segments with blind shaft and / or a wiper are placed on a pitched roof 1 and fastened with clamps 12.

[0027] Steps 11 can be installed between adjacent support beams 3 and / or counterweight beams 6 to facilitate maintenance of the solar modules 5.

[0028] It is also possible to use a solar panel mounting system where the position of the blind segments 8 can be controlled automatically, taking into account information received from sensors and the Internet about weather conditions, time of year and time of day.

[0029] An important feature of the proposed solar module mounting system is the ability to assemble the solar module mounting system 5 on the ground under factory conditions and deliver it to the roof in assembled condition using a lifting mechanism.

[0030] The presence of a shield ... on a different roof slope The counterweight beam 6 connected to the support beam 3 is a necessary element of the invention, since this new technical solution allows for an inventive step - the transfer of the load from the solar modules located on the support beam and their fixing system to the counterweight beam, thus creating the possibility of fixing the SCSP without fixing holes in the roof.

[0031] The feature ... consisting of at least one support beam on which at least one solar module is located directly or via at least one bracket attached to the support beam ... enables the technical implementation of the following feature of the invention: ... the mounting system for solar modules is mounted on the ground and, in the mounted state, transported to the roof via a lifting mechanism ...

[0032] The specified set of features contains an inventive step and allows solving the posed technical problem - to assemble an SCSP with solar modules 5, blind segments 8, blind shafts 9, automatic control devices, inverters, etc., entirely on the ground under factory conditions, to test its functionality and to mount it on the roof 1 without drilling holes in the roof, using lifting mechanisms and working at height with minimal use of manual labor.

[0033] This problem is solved by arranging a counterweight beam 6 on the roof slope 1, which is connected to a support beam 3 located on the other roof slope 1. If necessary, the support beam 3 and the counterweight beam 6 can be equipped with supports 2.

[0034] The particularity of using a counterweight beam 6 located on the other side of the roof 1 and connected to the support beam 3 is a necessary element of the invention since this new technical solution allows an inventive step - namely to balance the weight of the support beam 3 and all the parts connected to it and thereby generate the necessary clamping force, which until now was achieved by using anchors mounted through openings in the roof.

[0035] This feature allows, firstly, that no openings need to be made in the roof 1, secondly, that this construction can be used on all types of roofs 1 with different roof coverings, thirdly, that the labor costs for installing the solar modules 5 are reduced, fourthly, that protection for the solar modules 5 in the form of blind segments 8 and mechanisms for their movement (blind drums 9) can be mounted on the rigid support beam 3 and / or on the counterweight beam 6, fifthly, that a mechanism known from the prior art for cleaning the solar modules 11 can be mounted on the movable segments of the blinds 8, for example a brush with a cleaning agent, and sixthly, that a scraper 10 can be mounted in the lower part of the beams 6 and / or 3 to clean the segments of the blinds 8 of snow and ice when these segments of the blinds 8 move.

[0036] The above features characterize specific methods for implementing the proposed invention. The use of supports 2 allows the load of the SCSP to be concentrated at the locations of the load-bearing elements of the roof (above the purlins and rafters). The use of elastic material in the support 2 or the beams 3 and 6 allows for an even distribution of the load from the SCSP across the roof surface 1. Fastening the counterweight beam 6 and / or the support beam 3 to the underside of the roof overhang 1 using clamps 12 allows for an increase in their pressing force on the roof 1. The use of a hinged fastening 7 allows for the compensation of angle differences between different roof slopes 1. The installation of the declared SCSP devices pre-assembled on the ground using lifting mechanisms allows for a reduction in labor costs for the construction of a solar power plant.By using the blind segments 8, the solar modules 5 can be protected from hail, snow, and dirt. A cleaning mechanism in the form of a clip 10 allows cleaning of the solar modules 5. A scraper 10 allows cleaning of the blind segments 8 and removal of ice and snow. By using a previously unknown arrangement of blind segments 8 below and above the solar modules 5, it is possible to reduce the dimensions of the SCSP structure and eliminate the need for a separate blind drum 9 for supporting the blind segments 8 in the open position.
