Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic solar panels, and in particular to a fixing piece of an integrated water tank bracket of a photovoltaic panel, which is used for installing, supporting and fixing the photovoltaic panel. Background Art

[0002] At present, affected by the photovoltaic environment, large-scale photovoltaic power station projects have been growing rapidly in the past two years. The current situation of my country's large population and limited land has forced many photovoltaic power stations to develop on the roofs of large factories, but installing photovoltaic panels on the roof of a factory is different from installing them on the ground. In the BIPV (building integrated photovoltaic) field of the industry, photovoltaic panels are used as the roof of a building. Photovoltaic panels are generally installed on the purlins and beams of the building through brackets as the roof; in the BAPV (photovoltaic attached to a building) field of the industry, photovoltaic panels are generally installed on the surface of the top of the building (such as a colored steel tile roof) through brackets.

[0003] Existing photovoltaic systems all install photovoltaic modules on brackets through fixings, and the brackets are fixed on buildings. The bracket structure is an important component that determines the waterproof performance, and the structure of the fixings is the most important component that determines the installation efficiency and stability of the photovoltaic panels.

[0004] In the prior art, there is a sink bracket with a "J"-shaped fixing base + sink design. The fixing base is first fixed to the building, and then the sink is installed on the fixing base, and then the photovoltaic panel is horizontally mounted on the two sinks. Although it can effectively block rainwater and drain water quickly, this type of bracket is cumbersome to install and fix, has a complex structure, poor stability, and high installation cost.

[0005] In response to the above problems, our company has developed an integrated water tank bracket for photovoltaic panels (application number: CN201920199482.6), which perfectly solves the above problems. The above patent also provides an X-shaped fixing piece, which has a simple structure and a single function during use. It is necessary to align the photovoltaic panel and then fix the X-shaped fixing piece and the clamping piece at the same time, which is troublesome to operate and there is still the feasibility of further optimization. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a fixing piece for an integrated water tank bracket of a photovoltaic panel, which has a reasonable structure and good stability, and can improve the installation efficiency and installation stability of the photovoltaic panel.

[0007] The technical solution of the present invention:

[0008] A fixing part of an integrated water tank bracket of a photovoltaic panel, the water tank bracket comprising a water tank which is narrow at the top and wide at the bottom and is arranged in the middle, a support plate which is arranged at the edge of the water tank and is inclined upward, and a bracket for supporting and fixing the support plate, the fixing part comprising a lower clamping block arranged in the water tank, a middle clamping block pressed against the support plate, an upper pressing block for clamping and fixing the photovoltaic panel, and a bolt structure for tightening and fixing the lower clamping block, the middle clamping block, and the upper pressing block, wherein the width of the lower clamping block and the middle clamping block is greater than the width at the edge of the water tank.

[0009] Furthermore, the lower clamping block is a hollow isosceles trapezoidal structure that is narrow at the top and wide at the bottom, and a through hole for installing a bolt structure is provided at the center of the upper surface of the lower clamping block. The middle clamping block is a hollow isosceles trapezoidal structure that is wide at the top and narrow at the bottom, and the upper and lower surfaces of the middle clamping block are provided with through holes for accommodating the bolt structure in the same position. The upper pressure block is a splint structure, and a through hole for installing the bolt structure is provided at the center of the splint structure. The bolt structure comprises a bolt and two nuts, and the bolt passes through the upper surface of the lower clamping block, the upper surface of the middle clamping block, the nut, and the upper pressure block nut in sequence from bottom to top, and is fixed by tightening the two nuts.

[0010] Furthermore, a limiting protrusion is provided on the upper surface of the lower clamping block, and an upwardly concave limiting groove is provided on the lower surface of the middle clamping block, and the limiting protrusion and the limiting groove match in size.

[0011] Furthermore, the limiting protrusion includes two "7"-shaped screw clamping plates arranged opposite to each other, the spacing between the upper panels of the two screw clamping plates is greater than the diameter of the bolt screw, the bolt is a T-bolt, the spacing between the lower vertical plates of the two screw clamping plates is less than the length of the bolt head in the long direction, and the width of the head is less than the gap between the upper panels of the two screw clamping plates.

[0012] Furthermore, the upper surface of the middle clamping block is provided with two clamping edges for pressing outwards to position the photovoltaic panel, and the height of the clamping edges exceeds the highest point of the support plate.

[0013] Furthermore, the middle portion of the upper pressing block is concave downward to form a locking groove that presses outward to limit the photovoltaic panel, and the width of the locking groove is the same as the width of the locking edge.

[0014] Furthermore, the upper pressing block is provided with a snap-fit ​​structure for mounting and fixing a cover plate of the water tank bracket.

[0015] Furthermore, the snap-in structure is a strip-shaped snap-in protrusion arranged on the inner side walls on both sides of the snap-in slot, and the snap-in protrusion matches the snap-in on the outer side surfaces of two strips arranged on the bottom surface of the cover plate, and the gap between the two strips is smaller than the width of the snap-in slot.

[0016] Furthermore, when the middle clamping block is fixed, the height of the upper surface of the middle clamping block is lower than the highest point of the support plate.

[0017] Furthermore, the bracket is an oblique support plate formed by bending and extending the outer edge of the support plate downward and then bending and extending horizontally outward, and the horizontal bending section of the oblique support plate is fixed to the wall by bolts.

[0018] Compared with the prior art, the present invention fixes the lower clamping block and the middle clamping block at the notch of the water tank by bolts and nuts, and there is a half-section of bolt above the middle clamping block, and then the photovoltaic panel is horizontally mounted on the bracket, and then the photovoltaic panel is clamped and fixed by nuts and upper pressure blocks. The fixing parts of the present invention are fixed in two steps, first the fixing parts are fixed at the notch of the water tank, and then the photovoltaic panel is fixed and clamped. Since the photovoltaic panel is flat and has a large area, it is difficult for a person to go deep into the lower bracket to operate the original X-shaped fixing parts after it is horizontally mounted on the bracket. Therefore, the present invention has the effect of easy installation and improved installation efficiency, and the two-step fixation connects the photovoltaic panel and the bracket more firmly and tightly, thereby improving the stability and service life of the photovoltaic panel.

[0019] The lower clamp block and the middle clamp block of the isosceles trapezoidal structure can well match the shape of the sink bracket, have a large contact area with the sink bracket, are firmly and stably installed, and will not deflect to cause the bolt to loosen; the protrusion of the lower clamp block matches the groove of the middle clamp block, and further limits the lower clamp block and the middle clamp block to ensure that the two are installed and fixed on the sink bracket on the same axis, which is more firm, and there is no gap between the embedded lower clamp block and the middle clamp block, which completely prevents the possibility of loosening caused by deflection; the head of the bolt and the limiting protrusion of the lower clamp block are designed so that the head of the bolt is hooked on the bottom surface of the upper panel of the clamping screw plate, and the head of the bolt is stretched and fixed on the inner side wall of the lower vertical plate of the clamping screw plate by rotation, so that the clamping screw plate is stretched outward and fixed tightly together with the groove of the middle clamp block, so that the fixing of the lower clamp block and the middle clamp block is not only bolt fixing, but also clamping and fixing of the lower clamp block by the middle clamp block, making the connection more firm. The prismatic positioning edge on the middle clamp block can be used to position and limit the photovoltaic panel. During installation, the edge of the photovoltaic panel is directly placed against the side wall of the positioning edge for positioning. The installation is fast and accurate. The photovoltaic panel can also be positioned in the subsequent process to prevent deviation or skew. The positioning groove of the upper clamp block has the same function as the positioning edge, but at the same time, the bolts and nuts can be hidden below the plane of the photovoltaic panel to prevent the protruding bolts from scratching, and it is more beautiful. The design of the cover plate can prevent dead branches and leaves from falling into the sink and affecting the drainage of the sink. The buckle device design set between the cover plate and the upper pressure block is exquisitely designed. With a set of fixings, the photovoltaic panel and the sink bracket can be perfectly and firmly fixed together, thereby improving construction efficiency and reducing costs. The middle clamp block also supports the photovoltaic panel to improve stability. The integral bent sink bracket has better support, is more convenient and quick to make, has no welding, and is more solid and durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1:

[0027] A fixing part for an integrated water tank support of a photovoltaic panel, such as Figure 1 As shown, the water tank bracket 1 includes a water tank 11 which is narrow at the top and wide at the bottom and is arranged in the middle, a support plate 12 which is arranged at an angle upward along the edge of the water tank 11, and a bracket 13 for supporting and fixing the support plate 12. The fixing part 2 includes a lower clamping block 21 arranged in the water tank, a middle clamping block 22 pressed against the support plate 12, an upper pressing block 23 for clamping and fixing the photovoltaic panel 4, and a bolt structure 24 for tightening and fixing the lower clamping block 21, the middle clamping block 22, and the upper pressing block 23. The width of the lower clamping block 21 and the middle clamping block 22 is greater than the width of the edge of the water tank 11.

[0028] Furthermore, the lower clamping block 21 is a hollow isosceles trapezoidal structure that is narrow at the top and wide at the bottom, and a through hole for installing a bolt structure 24 is provided at the center of the upper surface of the lower clamping block 21. The middle clamping block 22 is a hollow isosceles trapezoidal structure that is wide at the top and narrow at the bottom, and the upper and lower surfaces of the middle clamping block 22 are provided with through holes for accommodating the bolt structure in the same position. The upper pressure block 23 is a splint structure, and a through hole for installing the bolt structure is provided at the center of the splint structure. The bolt structure 24 comprises a bolt 241 and two nuts 242, and the bolt passes through the upper surface of the lower clamping block, the upper surface of the middle clamping block, the nut, and the upper pressure block nut in sequence from bottom to top, and is fixed by tightening the two nuts.

[0029] Furthermore, a limiting protrusion 211 is provided on the upper surface of the lower clamping block 21 , and an upwardly concave limiting groove 221 is provided on the lower surface of the middle clamping block 22 . The limiting protrusion 211 and the limiting groove 221 match in size.

[0030] Furthermore, the limiting protrusion 211 includes two "7"-shaped screw clamping plates arranged opposite to each other, the spacing between the upper panels 2111 of the two screw clamping plates is greater than the diameter of the bolt screw rod, the bolt 241 is a T-bolt, the spacing between the lower vertical plates 2112 of the two screw clamping plates is less than the length of the head 2411 of the bolt 241 in the long direction, and the width of the head 2411 is less than the gap between the upper panels 2111 of the two screw clamping plates. Using this customized bolt to replace the circular bolt through hole of the original design not only saves the trouble of inserting the screw rod of the bolt into the through hole of the lower clamping block, making the installation simpler and easier to operate, but also the head of the bolt, after being tightened, moves along the arc direction to expand the lower vertical plate, so that the lower clamping block expands and presses against the middle clamping block, and the connection is more secure.

[0031] Furthermore, the upper surface of the middle clamping block 22 is provided with two locking edges 222 for pressing outwardly to position the photovoltaic panel, and the height of the locking edges 222 exceeds the highest point of the support plate 12 .

[0032] Furthermore, the middle portion of the upper pressing block 23 is concave downward to form a locking groove 231 that presses outward to limit the photovoltaic panel 4 , and the width of the locking groove 231 is the same as the width of the locking edge 222 .

[0033] Furthermore, the upper pressing block 23 is provided with a snap-fit ​​structure 31 for mounting and fixing the cover plate 3 of the water tank bracket.

[0034] Furthermore, the snap-fit ​​structure 31 is a strip-shaped snap-fitting protrusion 311 arranged on the inner side walls on both sides of the snap-fitting groove 231, and the snap-fitting protrusion 311 matches the snap-fitting 313 on the outer side surfaces of two strips 312 arranged on the bottom surface of the cover plate 3, and the gap between the two strips 312 is smaller than the width of the snap-fitting groove 231.

[0035] Furthermore, when the middle clamping block 22 is fixed, the height of the upper surface of the middle clamping block 22 is lower than the highest point of the support plate 12 .

[0036] Furthermore, the bracket 13 is a diagonal brace plate formed by bending and extending the outer edge of the support plate 12 downward and then bending and extending horizontally outward, and the horizontal bending section of the diagonal brace plate is fixed to the building by bolts.

[0037] Compared with the prior art, the present invention fixes the lower clamp and the middle clamp at the notch of the water tank by bolts and nuts, and there is a half bolt above the middle clamp, and then the photovoltaic panel is horizontally mounted on the bracket, and then the photovoltaic panel is clamped and fixed by nuts and upper pressure blocks. The fixing parts of the present invention are fixed in two steps, first fixing the fixing parts at the notch of the water tank, and then fixing and clamping the photovoltaic panel. Since the photovoltaic panel is flat and has a large area, after it is horizontally mounted on the bracket, the X-type fixing parts in the company's existing patents are difficult to install and inefficient, but the fixing parts of the present invention are easier to install and improve the installation efficiency compared with the X-type fixing parts, and the two-step fixing connects the photovoltaic panel and the bracket more firmly and tightly, improving the stability and service life of the photovoltaic panel.

[0038] The lower clamp block and the middle clamp block of the isosceles trapezoidal structure can well match the shape of the sink bracket, have a large contact area with the sink bracket, are firmly and stably installed, and will not deflect to cause the bolt to loosen; the protrusion of the lower clamp block matches the groove of the middle clamp block, and further limits the lower clamp block and the middle clamp block to ensure that the two are installed and fixed on the sink bracket on the same axis, which is more firm, and there is no gap between the embedded lower clamp block and the middle clamp block, which completely prevents the possibility of loosening caused by deflection; the head of the bolt and the limiting protrusion of the lower clamp block are designed so that the head of the bolt is hooked on the bottom surface of the upper panel of the clamping screw plate, and the head of the bolt is stretched and fixed on the inner side wall of the lower vertical plate of the clamping screw plate by rotation, so that the clamping screw plate is stretched outward and fixed tightly together with the groove of the middle clamp block, so that the fixing of the lower clamp block and the middle clamp block is not only bolt fixing, but also clamping and fixing of the lower clamp block by the middle clamp block, making the connection more firm. The prismatic positioning edge on the middle clamp block can be used to position and limit the photovoltaic panel. During installation, the edge of the photovoltaic panel is directly placed against the side wall of the positioning edge for positioning. The installation is fast and accurate. The photovoltaic panel can also be positioned in the subsequent process to prevent deviation or skew. The positioning groove of the upper clamp block has the same function as the positioning edge, but at the same time, the bolts and nuts can be hidden below the plane of the photovoltaic panel to prevent the protruding bolts from scratching, and it is more beautiful. The design of the cover plate can prevent dead branches and leaves from falling into the sink and affecting the drainage of the sink. The buckle device design set between the cover plate and the upper pressure block is exquisitely designed. With a set of fixings, the photovoltaic panel and the sink bracket can be perfectly and firmly fixed together, thereby improving construction efficiency and reducing costs. The middle clamp block also supports the photovoltaic panel to improve stability.
