Description

Technical Field

[0001] The utility model relates to a wooden roof panel photovoltaic support structure, belonging to the technical field of photovoltaic panel installation. Background Art

[0002] With the popularization of photovoltaic power generation, photovoltaic panels can be installed on roofs, ground, water surface and other locations. The installation environment can also adapt to the harsh weather conditions in the desert and the humid weather conditions in the mountains. Therefore, the installation freedom of photovoltaic panels is relatively high.

[0003] In real life, civilian photovoltaic panels are usually installed on roofs, but some roofs and main structures are wooden structures. When installing photovoltaic panels on wooden structures, screws are required to connect the photovoltaic panel support structure to the wooden structure. When the screws are screwed or nailed into the wooden structure, cracks are prone to occur at the nail holes of the wooden structure, which affects the connection strength of the photovoltaic panels and greatly reduces the connection strength and stability. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a wooden roof panel photovoltaic support structure, which solves the problem in the prior art that cracks are easily generated at the nail holes connecting the photovoltaic panels and the wooden structure, thereby affecting the connection strength of the photovoltaic panels and greatly reducing the connection strength and stability.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a photovoltaic support structure of a wooden roof panel, comprising a heavy wood structure, a wooden top structure and a photovoltaic panel assembly, wherein the heavy wood structure supports the wooden top structure, and a plurality of wooden boards are fixedly installed on the wooden top structure, and there are gaps between adjacent wooden boards, wherein the photovoltaic panel assembly comprises a photovoltaic panel structure, a connecting structure and a supporting structure, wherein the connecting structure comprises a vertical supporting piece, a horizontal supporting piece, an abutting piece, a connecting bolt, a pressure spring, a connecting nut and a limiting block, wherein the vertical supporting piece is vertically arranged and the horizontal supporting piece and the abutting piece are respectively fixedly arranged at the vertical ends of the same side of the vertical supporting piece, wherein the vertical supporting piece, the horizontal supporting piece and the abutting piece form a main connecting frame, wherein the two main connecting frames form a group and the two main connecting frames are symmetrically arranged, and the connecting frame is connected to the photovoltaic panel structure. The axial level of the connecting bolt passes through the two vertical support plates located in the same group of main connecting frames, and the connecting nut is threadedly connected to the end of the connecting bolt away from the bolt head. There is a gap between the two vertical support plates in the same group of main connecting frames, and a limit block is arranged in the gap and is threadedly connected to the connecting bolt. The pressure spring is sleeved on the connecting bolt and arranged between the limit block and the vertical support plate. The two ends of the pressure spring are respectively fixedly connected to the vertical support plate and the limit block. The supporting structure is fixed to a side of the horizontal support plate away from the vertical support plate, the photovoltaic panel structure is connected to the supporting structure, and the vertical support plate is provided with an abutment plate at one end, which extends through the gap between adjacent wooden boards to the side of the wooden board facing the wooden top structure and abuts against the wooden top structure. The abutment plate is located on the side of the wooden board facing the wooden top structure and abuts against the wooden board.

[0006] By adopting the above technical scheme, the end of the vertical support piece is abutted against the wooden top structure, and the abutting piece is abutted against the wooden board. At this time, the displacement of the main connecting frame in the vertical direction can be limited. Then, by connecting the connecting bolts on the main connecting frame and tightening them with the connecting nuts and the limit blocks, the spacing between the two main connecting frames can be fixed. Since the interval between the wooden boards is fixed and the edges of the gaps between the vertical support piece and the wooden boards are always in an extruded state and there is friction under the fixing action of the connecting nuts and the limit blocks, the purpose of limiting the horizontal displacement of the two main connecting frames can be achieved under the action of friction and the fixed gap between the wooden boards. At this time, the connecting structure can be stably connected to the wooden boards and there is no need to use screws to punch holes or the like to connect to the wooden structure, which reduces the probability of cracking at the connection of the wooden boards, which is beneficial to improving the connection strength and connection stability between the photovoltaic panel and the wooden structure. At the same time, the elastic force of the pressure spring always makes the limit block face the side of the abutted vertical support piece. At this time, the limit block is not prone to the problem of self-spin loosening during practical use, further ensuring the connection stability between the photovoltaic panel and the wooden structure.

[0007] The utility model is further configured as follows: there is a space between the connecting bolt and the wooden board and a clamping plate fixedly connected to the vertical support plate is detachably arranged in the space, and a rubber gasket sleeved on the connecting bolt is arranged between the bolt head of the connecting bolt and the vertical support plate and between the connecting nut and the vertical support plate.

[0008] By adopting the above technical scheme, after the clamping plate is fixed to the vertical support plate, it jointly supports the wooden board with the abutment plate, thereby further limiting the vertical movement of the vertical support plate, which is beneficial to strengthening the vertical connection strength between the main connecting frame and the wooden board. At the same time, the rubber gasket can prevent the connecting bolts, connecting nuts and limit blocks from applying excessive pressure to the vertical support plate after the two main connecting frames are fixed to the wooden board, causing deformation of the surface of the vertical support plate, which is beneficial to protecting the practical life of the vertical support plate.

[0009] The utility model is further configured as follows: the supporting structure includes a supporting profile, a plug-in groove, a limiting profile, an expansion cavity, a tightening threaded rod, a first connecting nut sleeve and a second connecting nut sleeve, the supporting profile is fixedly connected or abutted with the horizontal supporting piece, two supporting profiles are arranged side by side and there is a space between adjacent supporting profiles, the plug-in groove is arranged on the side of the supporting profile away from the horizontal supporting piece and towards the side where the two supporting profiles are away from each other, one end of the limiting profile extends between the two supporting profiles, and the other end of the limiting profile abuts against the end face of the side of the supporting profile away from the horizontal supporting piece, the expansion cavity is opened in the limiting profile and is provided with an opening facing the side away from the horizontal supporting piece, the tightening threaded rod is arranged in the expansion cavity, one end of the tightening threaded rod extends toward the direction of the horizontal supporting piece and penetrates the limiting profile and the horizontal supporting piece, the first connecting nut sleeve is rotatably arranged on the end wall of the side of the expansion cavity away from the opening, the second connecting nut sleeve is rotatably arranged on the end face of the side of the horizontal supporting piece away from the supporting profile, the first connecting nut sleeve and the second connecting nut sleeve are threadedly connected with the tightening threaded rod, and the photovoltaic panel structure is plugged into the plug-in groove.

At this time, the two ends of the photovoltaic panel structure can be plugged into the plug-in grooves on the adjacent supporting structure, thereby maintaining the stability of the photovoltaic panel structure. There is no need to remove the locking parts during disassembly and repair, and disassembly and maintenance are relatively convenient. When the supporting profile abuts against the horizontal supporting sheet, the supporting profile limits the vertical movement of the supporting profile and applies pressure to the supporting profile toward the horizontal supporting sheet. At this time, the supporting profile is tightly abutted against the horizontal supporting sheet, and the two ends of the clamping threaded rod are respectively threadedly connected through the first connecting nut sleeve and the second connecting nut sleeve so that the limiting profile can provide continuous pressure to the supporting profile, thereby ensuring the stability of the supporting profile.

[0011] The utility model is further configured as follows: a sliding groove is provided on one side of two vertical support pieces in the same group that are away from each other, a pressure plate is slidably arranged in the sliding groove, the side of the pressure plate that is away from the vertical support piece extends to the outside of the sliding groove and can abut against the connecting bolt, the end of the tightening threaded rod abuts against the pressure plate, and adjustment grooves extending in the same direction as the sliding groove are provided on two opposite sides of the sliding groove, the connecting bolt passes axially through the adjusting groove and the connecting bolt can slide along the extending direction of the adjusting groove.

[0012] By adopting the above technical solution, by rotating the clamping threaded rod and keeping the first connecting nut sleeve and the second connecting nut sleeve stationary, the clamping threaded rod is made to move axially under the action of the thread, so that the end of the clamping threaded rod can push the pressure plate toward the direction of the connecting bolt, and finally make the pressure plate abut against the connecting bolt, thereby limiting the vertical sliding of the connecting bolt, which is beneficial to improving the stability of the connecting bolt after connection, and due to the setting of the above-mentioned clamping plate, the connecting bolt can generate pressure on the clamping plate toward the abutment plate under the pressure of the pressure plate. At this time, the clamping plate and the abutment plate have a clamping effect on the wooden board, thereby further improving the connection stability between the main connecting frame and the wooden board.

[0013] The utility model is further configured as follows: an expansion plate is fixedly installed at the opening of the expansion cavity, a fixing column is detachably clamped on the expansion plate, one end of the fixing column extends into the expansion cavity, the other end of the fixing column extends to a side of the expansion plate away from the horizontal support sheet, an outer side of one end of the fixing column away from the horizontal support sheet is threadedly connected to a limiting nut, and one end of the fixing column away from the horizontal support sheet is threadedly connected to a fixing bolt, the photovoltaic panel structure is installed on a side of the fixing column away from the horizontal support sheet, and the fixing bolt limits the movement of the photovoltaic panel structure by passing through the photovoltaic panel structure and being threadedly connected to the fixing column.

[0014] By adopting the above technical solution, when the natural environment in which the photovoltaic panel structure is located is relatively harsh, the photovoltaic panel structure and the fixed column are locked and fixed by fixing bolts, which can avoid the photovoltaic panel falling off due to external wind force to the greatest extent. Compared with the above-mentioned plug-in structure, this connection method has a higher upper force limit.

[0017] The beneficial effect of the utility model is that the end of the vertical support piece is abutted against the wooden top structure, and the abutting piece is abutted against the wooden board, so that the displacement of the main connecting frame in the vertical direction can be limited. Then, by connecting the connecting bolts on the main connecting frame and tightening them with the connecting nuts and the limit blocks, the spacing between the two main connecting frames can be fixed. Since the interval between the wooden boards is fixed and the edges of the gaps between the vertical support piece and the wooden boards are always in an extruded state and there is friction under the fixing action of the connecting nuts and the limit blocks, the purpose of limiting the horizontal displacement of the two main connecting frames can be achieved under the action of the friction and the fixed gap between the wooden boards. At this time, the connecting structure can be stably connected to the wooden board and there is no need to use screws to punch holes and the like to connect to the wooden structure, which reduces the probability of cracking at the connection of the wooden board, which is beneficial to improving the connection strength and connection stability between the photovoltaic panel and the wooden structure. At the same time, the elastic force of the pressure spring always makes the limit block face the side of the abutted vertical support piece.

[0027] like Figure 2 and Figure 5As shown, there is a space between the connecting bolt 20 and the wooden board 15, and a clamping plate 25 fixedly connected to the vertical support sheet 10 is detachably arranged in the space, and a rubber gasket 21 sleeved on the connecting bolt 20 is arranged between the bolt head of the connecting bolt 20 and the vertical support sheet 10 and between the connecting nut 23 and the vertical support sheet 10.

[0029] like Figure 2 and Figure 6As shown, a sliding groove 11 is provided on one side of two vertical support sheets 10 of the same group that are away from each other, and a pressure plate 26 is slidably arranged in the sliding groove 11.

[0031] Example 1

[0032] The photovoltaic panel structure includes a plug-in photovoltaic panel frame 38 and a plug-in photovoltaic panel 39. The plug-in photovoltaic panel frame 38 is arranged on opposite sides of the plug-in photovoltaic panel 39 and is fixedly connected to the plug-in photovoltaic panel 39. The end of the plug-in photovoltaic panel frame 38 away from the plug-in photovoltaic panel 39 is inserted into the plug-in slot 31 to form a plug-in structure.

[0033] Example 2

[0034] The photovoltaic panel structure includes a fixed photovoltaic panel frame 44 and a fixed photovoltaic panel 45. The fixing bolts 43 vertically penetrate the fixed photovoltaic panel frame 44 and are threadedly connected to the fixing columns 41. The fixed photovoltaic panels 45 are fixedly arranged on two opposite sides of the fixed photovoltaic panel frame 44.

[0035] By abutting the end of the vertical support piece 10 against the wooden top structure, and abutting the abutting piece 14 against the wooden board 15, the displacement of the main connecting frame in the vertical direction can be limited. Then, by connecting the connecting bolts 20 to the main connecting frame and tightening them with the connecting nuts 23 and the limit blocks 24, the spacing between the two main connecting frames can be fixed. Since the intervals between the wooden boards 15 are fixed and the edges of the gaps between the vertical support piece 10 and the wooden boards 15 are always in an extruded state and friction exists under the action of the friction and the wooden board. The fixed gap between the boards 15 can limit the horizontal displacement of the two main connecting frames. At this time, the connecting structure can be stably connected to the wooden board 15 and there is no need to use screws to drill holes or other methods to connect to the wooden structure, which reduces the probability of cracking at the connection between the wooden board 15, and is beneficial to improving the connection strength and stability between the photovoltaic panel and the wooden structure. At the same time, the elastic force of the pressure spring 22 always makes the limit block 24 face the side of the abutting vertical support piece 10. At this time, the limit block 24 is not prone to the problem of self-spin loosening during practical use, further ensuring the connection stability between the photovoltaic panel and the wooden structure.

[0036] When the external environment of the photovoltaic panel is relatively stable and not prone to adverse weather conditions, the photovoltaic panel structure can be installed by plugging into the plug-in slot 31. When the support profile 30 is fixedly connected to the horizontal support sheet 13, the photovoltaic panel structure can be plugged into the plug-in slot 31. At this time, the two ends of the photovoltaic panel structure can be plugged into the plug-in slot 31 on the adjacent support structure, thereby maintaining the stability of the photovoltaic panel structure. There is no need to remove the locking piece during disassembly and repair, and disassembly and maintenance are relatively convenient. When the support profile 30 abuts against the horizontal support sheet 13, the support profile 30 limits the vertical movement of the support profile 30 and applies pressure to the support profile 30 toward the horizontal support sheet 13. At this time, the support profile 30 is tightly abutted against the horizontal support sheet 13, and the two ends of the compression threaded rod 34 are respectively threadedly connected through the first connecting nut sleeve 35 and the second connecting nut sleeve 36 so that the limiting profile 32 can provide continuous pressure to the support profile 30, thereby ensuring the stability of the support profile 30.

[0037] By rotating the clamping threaded rod 34 and keeping the first connecting nut sleeve 35 and the second connecting nut sleeve 36 stationary, the clamping threaded rod 34 is moved axially under the action of the thread, so that the end of the clamping threaded rod 34 can push the pressure plate 26 toward the connecting bolt 20, and finally make the pressure plate 26 abut against the connecting bolt 20, thereby limiting the vertical sliding of the connecting bolt 20, which is beneficial to improving the stability of the connecting bolt 20 after connection. In addition, due to the setting of the above-mentioned clamping plate 25, the connecting bolt 20 can generate pressure on the clamping plate 25 toward the abutment sheet 14 under the pressure of the pressure plate 26. At this time, the clamping plate 25 and the abutment sheet 14 have a clamping effect on the wooden board 15, thereby further improving the connection stability between the main connecting frame and the wooden board 15.

[0038] When the natural environment in which the photovoltaic panel structure is located is relatively harsh, the photovoltaic panel structure and the fixing column 41 are locked and fixedly connected by the fixing bolts 43, which can avoid the photovoltaic panel falling off due to external wind force to the greatest extent. Compared with the above-mentioned plug-in structure, this connection method has a higher upper force limit.

[0039] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model.
