Description
Technical Field
The invention relates to the technical field of photovoltaic module supporting structures, in particular to an arched roof photovoltaic bracket. The invention also relates to an arched roof photovoltaic bracket with the arched roof photovoltaic bracket.
Background
The solar photovoltaic power generation system refers to a power generation system which is formed by utilizing solar energy and adopting special material electronic elements such as a crystalline silicon plate, an inverter and the like, is connected with a power grid and transmits power to the power grid. The solar photovoltaic power generation system mainly comprises a solar cell matrix, a storage battery pack, a charge-discharge controller, an inverter, an alternating current power distribution cabinet and a solar tracking control system. The world energy crisis promotes the rapid development of new energy industry, solar energy is the most important basic energy source in various renewable energy sources, and the application range of the solar photovoltaic power generation system is more and more wide in recent years, and the solar photovoltaic power generation system is applied to a plurality of industries.
The solar photovoltaic bracket (hereinafter referred to as photovoltaic bracket) is a special bracket designed for placing, installing and fixing a solar cell array in a solar photovoltaic power generation system. The design requirements for the photovoltaic bracket are: (1) The structure must be robust and reliable to withstand, for example, atmospheric corrosion, wind loads and other external effects. (2) The installation cost is low, and the maximum use effect is achieved with the minimum installation cost as much as possible. And (3) the maintenance cost is low. Maintenance-free or lower maintenance costs can be achieved as much as possible. The material selection principle of the photovoltaic bracket is as follows: materials with high wear resistance are selected as much as possible to resist wind and snow loads and other corrosive effects. The materials generally selected are aluminum alloy, carbon steel and stainless steel. The material further comprehensively utilizes the technical processes of aluminum alloy anodic oxidation, ultra-thick hot galvanizing, UV aging resistance and the like to improve the service life of the photovoltaic bracket and the solar tracking system.
Most of the existing photovoltaic brackets are installed on a wide ground, but this requires a large area of open area. However, those skilled in the art find that the roof of many large buildings can also be used for installing photovoltaic brackets, and the generated energy of the photovoltaic modules can be further improved after the photovoltaic modules are installed on the roof, so that the purpose of more efficiently utilizing solar energy is achieved. Photovoltaic brackets have been found to be mounted on flat or sloping roofs.
However, unlike installing photovoltaic brackets on the ground, the roof of a building is more limited in the manner in which the photovoltaic brackets are connected. That is, the installation of the photovoltaic bracket cannot damage the structure of the roof and cannot affect the waterproofing of the building, in addition, as the roof of the building has a certain height, after the photovoltaic bracket is installed on the roof, the photovoltaic bracket is positioned in the mid-air, and the wind speed in the high air is higher, so that the connection strength requirement on the photovoltaic bracket on the roof is higher. However, the conventional photovoltaic support is basically connected to the embedded device, and the embedded device needs to be fixedly connected to the roof. However, the fixing of the burying device to the roof is necessary to destroy the roof structure or increase the weight of the roof, which causes damage to the house, destroy the structure of the building, etc. Because of the above problems, many users are reluctant to accept the installation of photovoltaic brackets on roofs. Moreover, the roof types of buildings are many, especially arched or roof comprising an arc structure, on which the installation of the burying device is not only difficult, but also more damaging than planar or sloping roofs.
In addition, on the arch surface or the roof comprising the cambered surface structure, the photovoltaic bracket is inevitably subjected to integral deformation when the temperature changes, namely the integral length of the photovoltaic bracket is increased or contracted, the accumulated deformation amount is along the arch surface or the cambered surface on the arch surface or the roof comprising the cambered surface structure, namely the deformation amount is in a cambered shape, and therefore, the requirement on the compensation of the deformation is higher. The compensation of the deformation is required to be carried out along the arch surface or the cambered surface, and the stability of the photovoltaic bracket of the arch roof is ensured when the compensation is carried out.
In summary, how to provide a photovoltaic bracket that hardly damages a building when installed; the application range is wide, and the device can be installed on roofs with various shapes; the roof with various shapes has better deformation compensation function, and is a problem to be solved urgently by the person skilled in the art. Based on the above, the invention provides an arched roof photovoltaic bracket and an arched roof photovoltaic bracket to solve the technical problems.

Examples
As shown in fig. 1-8, in this embodiment an arched roof photovoltaic support is provided for an arched roof 6, the arched roof 6 being provided on a depending body 7. The arched roof photovoltaic bracket comprises a pull rod 3, a support assembly 2, an anchoring piece 1, a support assembly 2 and an angle adjusting assembly 4. The plurality of pull rods 3 and the plurality of support assemblies 2 are arranged, the pull rods 3 and the support assemblies 2 are alternately arranged, and one pull rod 3 is arranged between every two support assemblies 2. The free end of the foremost tie rod 3 is connected to the anchor 1 and the free end of the foremost tie rod 3 is connected to the angular adjustment assembly 4. The photovoltaic support comprises an anchor 1, a pull rod 3, alternating units of support assemblies 2 and pull rods 3, pull rods 3 and an angle adjusting assembly 4 which are sequentially connected from the beginning end to the end of the arched roof photovoltaic support, wherein the support assemblies 2 and the pull rods 3 are arranged at the two ends respectively in the alternating units of the support assemblies 2 and the pull rods 3, and the pull rods 3 and the support assemblies 2 are alternately connected in the middle.
The anchoring piece 1 fixes the arched roof photovoltaic support and the attaching body 7. The tie rod 3 is used for mounting a photovoltaic module (mainly a solar panel). The support assembly 2 comprises a land 22 and a rotating arm 21, the land 22 is abutted against the arched roof 6, one end of the rotating arm 21 is rotatably connected with the land 22, the other end of the rotating arm 21 is rotatably connected with the pull rods 3, two pull rods 3 are arranged on one rotating arm 21, and the other ends of the two pull rods 3 are respectively connected with the rotating arm 21 of the adjacent support assembly 2.
Because the land 22 is abutted with the arched roof 6, the land 22 and the arched roof 6 do not need to be anchored before, and the arched roof 6 and the attached body 7 thereof are not damaged. Since the anchor 1 is arranged at the initial end, the anchor 1 fixedly connects the pull rod 3 at the initial end with the arched roof 6 or the attaching body 7 thereof. If the anchoring piece 1 is fixedly connected with the attaching body 7, the photovoltaic bracket of the arched roof and the roof have no anchoring points, and the structure of the arched roof 6 is not damaged at all. If the anchor 1 is fixedly connected to the arched roof 6, only one anchoring point is present. Therefore, the arched roof photovoltaic support of the present application open arch has little effect of damaging the attached structure.
However, considering that the arched roof photovoltaic support is used for supporting the solar photovoltaic module, the solar photovoltaic module is usually installed outdoors, and the problem of expansion caused by heat and contraction caused by cold of the support with a large-scale steel structure cannot be ignored. Therefore, the arched roof photovoltaic support of the present application open arch is also provided with an angular adjustment assembly 4. The angular adjustment assembly 4 is connected to the endmost tie rod 3, i.e. the end remote from the anchor 1. The angle adjusting assembly 4 is used for compensating the total deformation of the arched roof 6 of all the pull rods 3.
Because the support assembly 2 comprises the land 22 and the rotating arm 21, the land 22 is abutted against the arched roof 6, one end of the rotating arm 21 is rotationally connected with the land 22, and the other end of the rotating arm 21 is rotationally connected with the pull rod 3. Taking an example of an increase in ambient temperature, where the tie rods 3 are extended, the swivel arms 21 of the support assemblies 2 will rotate around the floor 22, so that the extension of the tie rods 3 is accumulated by all the support assemblies 2 to the endmost tie rods 3, where the angular adjustment assemblies 4 located on the endmost tie rods 3 are used to compensate for the total deformation of all the arched roof 6 extending over the tie rods 3. The arched roof photovoltaic bracket is used for fixing the photovoltaic module, so that even if the arched roof photovoltaic bracket is used on an arched roof, the arched roof photovoltaic bracket can still ensure a better fixing effect even if the anchoring points are fewer.
As shown in fig. 4 and 5, further, the boom 21 is hinged to the floor 22 on the basis of the above embodiment. In order to increase the connection strength of the rotating joint of the rotating arm 21 and the ground disc 22, a larger and thicker pin shaft 23 is used, and in order to avoid bending deformation of the pin shaft 23, the structures of the rotating arm 21 and the ground disc 22 are reasonably designed so as to relatively separate the position of the stressed pivot of the pin shaft 23.
Further, on the basis of the above embodiment, an axial adjusting assembly 5 is arranged between the endmost pull rod 3 and the angular adjusting assembly 4, and the axial adjusting assembly 5 is used for adjusting the length of the endmost pull rod 3. The axial adjusting component 5 can compensate the deformation in the direction of the extension rod 3; on the other hand, the photovoltaic bracket can be adjusted according to the on-site condition during installation, so that the application range of the arched roof photovoltaic bracket is wider, and the universality is better.

The telescopic piece can be a telescopic rod; the axial adjusting component 5 can also cut off the last pull rod 3, one side of the cut-off part is provided with an internal thread, the other side is provided with an external thread, the internal thread and the external thread are sleeved and screwed, and the threads can be threads with good self-locking property.
Further, on the basis of the above embodiment, the axial adjustment assembly 5 uses a stud bolt, one end of which is connected to the tie rod 3, and the other end of which is connected to the attachment body 7. The turnbuckle is a part for adjusting tightness by utilizing the extension and contraction of a screw rod, and is also called a turnbuckle or a wire tightening buckle of a rigging.
On the basis of the above embodiment, further, the anchoring member 1 uses an anchoring screw, and a connecting portion is correspondingly arranged on the pull rod 3, and the anchoring screw passes through the connecting portion to be connected with the attaching body 7. Considering that the pull rod 3 is rod-shaped, a large stress area may not exist during anchoring, so that a connecting part is arranged, and the connecting part can be sheet-shaped. In addition, an inner screw hole can be arranged at the connecting part to enlarge the screw joint area of the screw thread on the anchoring screw rod.
The angle adjusting assembly 4 may have various structures, for example, a support may be provided on the attaching body 7, and a pulley may be provided on the support (similar to the structure of a fixed pulley). The pull rod 3 at the tail end is connected with a section of flexible rope which is wound on the fixed pulley. The purpose of compensating the total deformation of the arched roof 6 of all the pull rods 3 is achieved by tightening and releasing the flexible ropes.

One end of the fixing rod 42 is connected with the baffle 46, and the other end extends out of the base 41 through a through hole in the base 41 and is in sliding connection with the inside of the through hole. The spring 43 is sleeved on the fixing piece, and two ends of the spring are respectively abutted against the baffle 46 and the inner wall of the base 41. One end of the fixing rod 42 extending out of the base 41 is rotatably connected with one end of the pull ring 45, and the other end of the pull ring 45 is rotatably connected with the flower plate rotating arm 44.
The pattern plate rotating arm 44 is of a plate-shaped structure, the pattern plate rotating arm 44 and the energy storage suite are respectively arranged at two ends of the base 41, and the pattern plate rotating arm 44 is arranged outside the base 41. The pollen plate rotating arm 44 includes a fixed rotating hole, a first connecting hole 491 and a second connecting hole 492, and the fixed rotating hole is rotatably connected with the base 41. The first connecting hole 491 is arranged near the pull rod 3, and the first connecting hole 491 is connected with the pull ring 45 in a rotating way; the second connecting hole 492 is arranged close to the energy storage sleeve member, and the second connecting hole 492 is rotatably connected with the pull rod 3.
The spline rotating arm 44 is used for stably adjusting the position of the pull rod 3 when the pull rod 3 has overall length change, and on one hand, the overall displacement of the pull rod 3 after deformation is in a controllable state; on the other hand, the deformation process of the pull rod 3 is relatively stable, and the pull rod 3 maintains a relatively balanced stress state even in deformation, so that the change of the whole system is synchronous. The energy storage package comprises a spring 43 in a compressed state, the spring 43 in the compressed state having elastic potential energy.
In order to ensure that the photovoltaic module can be firmly connected to the photovoltaic module, the tension of the tie rod 3 on the tie rod is required to be approximately unchanged in the process of changing, namely to be fluctuated in a small range. The angular adjustment assembly 4 in this embodiment therefore has the function of changing the moment of the pull-up force of the tie rod 3, the adjustment principle of which is as follows:
Because the pull rod 3 is a rigid rod, the stress state is a pulling and pressing state, and therefore the acting line of the pulling force on the pull rod 3 is along the direction of the rod. Since the tie rod 3 is connected with the pattern plate rotating arm 44, and the pattern plate rotating arm 44 is a plate rotating around a fixed shaft, the rotation center of the pattern plate rotating arm 44 is the rotation center of the tie rod 3. Since the rotation moment of the pull rod 3 is the product of the pulling force and the arm thereof, and the work done by the rotation moment of the pull rod 3 is provided by the elastic potential energy of the spring 43. Therefore, in the case that the work performed by the rotation moment of the pull rod 3 is constant, the tension arm of the pull rod 3 is changed to ensure that the tension of the pull rod 3 is unchanged. The arm of force of the pull rod 3 is the vertical distance between the pull rod 3 and the rotation center of the pull rod. When each tie rod 3 of the arched roof photovoltaic bracket is deformed, the amount of deformation accumulated to the endmost tie rod 3 is adjusted by rotation of the flower plate rocker arm 44. That is, the flower plate rotating arm 44 rotates along with the change of the acting line direction of the pull force of the pull rod 3, so that the magnitude of the force arm of the pull force of the pull rod 3 is changed, and the aim of keeping the tension in the pull rod 3 constant is fulfilled.
Further to the above embodiments, the retaining rod 42 of the energy storage kit is screwed with the baffle 46. The fixing rod 42 is screw-connected with the baffle 46, so that the compression amount of the spring 43 can be adjusted by adjusting the position of the baffle 46, and the purpose of changing elastic potential energy can be achieved.
Further, on the basis of the above embodiment, the position where the pollen plate rotary arm 44 is rotatably connected to the base 41 is defined as the third connecting hole 48, and then the distance between the first connecting hole 491 and the third connecting hole 48 is different from the distance between the second connecting hole 492 and the third connecting hole 48. In the process of adjusting the arm of the pull rod 3 to ensure constant tension in the pull rod 3, the ground disc 22 of the support assembly 2 connected with the pull rod 3 is always abutted against the arched roof 6, so that the component force of the tension of the pull rod 3 in the direction vertical to the arched roof 6 is ensured to be sufficient, and the adjustment of the distance between the connecting holes is realized.
As shown in fig. 8, since the arc roof 6 to which the photovoltaic bracket is attached has a different surface curvature, in order to further improve the versatility of the photovoltaic bracket for an arc roof, a plurality of second connection holes 492 are provided, and the plurality of second connection holes 492 are all provided on the plate surface of the deck rotating arm 44. With the distance between the first connection hole 491 and the third connection hole 48 as a reference distance, the distance between the second connection hole 492 and the third connection hole 48 may be larger or smaller than the reference distance, and a series of distances may be provided to satisfy the need.
On the basis of the above embodiment, further, the pull ring 45 includes a first support arm and a second support arm, one ends of the first support arm and the second support arm are rotationally connected with the adjusting lever, an avoidance groove is formed between the first support arm and the second support arm, and the pull rod 3 passes through the avoidance groove. The other ends of the first and second arms are provided with a pattern plate rotating arm 44, respectively. The two flitch arms 44 are each connected to two arms by a pin 47. The pull ring 45 with the structure has better effect and longer service life when rotating. In addition, the pull rod 3 can pass through the middle of the pull ring 45, thereby protecting the pull rod 3 and increasing the acting area of a rotating point of the pull ring 45 in rotating connection.
The invention also provides an arched roof photovoltaic power station, which comprises an arched roof photovoltaic bracket and a photovoltaic module, wherein the photovoltaic module is connected with the pull rod 3 of the arched roof photovoltaic bracket. Taking a solar cell panel as an example of the photovoltaic module, when the photovoltaic module is used, one solar cell panel can be fixed on the pull rod of the group of arched roof photovoltaic brackets, and at the moment, the middle part of the back surface of the solar cell panel is fixed with the pull rod, and the edges of the adjacent panels are connected. Two groups of arched roof photovoltaic supports can be used for fixing a solar panel, namely two pull rods of the two groups of supports are used for respectively fixing two side edges of the solar panel.
