Description

Technical Field

[0001] The invention belongs to the technical field of urban noise reduction construction, and in particular relates to a photovoltaic assembly of a built sound barrier and an installation method. Background Art

[0002] With the rapid advancement of urbanization, traffic noise pollution has become a key issue that seriously affects the quality of life of residents and the urban environment. Traditional sound barriers are widely used on both sides of urban roads, highways, railways and other traffic arteries, effectively reducing noise transmission, but their functions are single, focusing only on sound insulation, and not making full use of the space resources they occupy.

[0003] In recent years, solar energy technology has developed rapidly and environmental awareness has increased. Photovoltaic sound barriers combine solar photovoltaic technology with traditional sound barriers to achieve sound insulation and power generation functions, and have attracted much attention in the market.

[0004] Since there are a large number of existing sound barriers and they are located on both sides of traffic arteries with abundant solar energy resources, directly replacing them with photovoltaic sound barriers will not only be costly and time-consuming, but will also have many adverse effects on traffic and the surrounding environment. Therefore, the best solution is to further install photovoltaic modules based on the location of the existing sound barriers to enable them to perform their performance and utilize the solar energy resources at their location.

[0005] Currently, photovoltaic modules are usually equipped with corresponding installation mechanisms to fix photovoltaic panels. However, since the construction site is next to a major traffic artery, road transportation safety must be ensured, which places extremely high demands on the safety of construction operations and installation structures.

[0006] First point: The sound barriers are located on both sides of the road, which results in limited construction space for photovoltaic modules. On the one hand, the installation mechanisms of some photovoltaic panels may be too large or complicated to be installed efficiently without affecting traffic. On the other hand, the existing photovoltaic modules are installed in a way that tilts outward to increase the tracking angle of the photovoltaic panels, which increases the probability of traffic safety accidents and poses a traffic hazard.

[0007] Second, the harsh external environment, especially strong winds, poses a great threat to the stability of photovoltaic panel installation. Existing photovoltaic modules are often not well designed for wind resistance, and photovoltaic panels and fixing mechanisms may become loose, deformed, or even fall off under strong winds. If such a situation occurs, the probability of traffic accidents will be further increased.

[0008] Third, existing photovoltaic module installation solutions usually require drilling holes in the connecting main beams to facilitate subsequent installation with bolts. Once this installation method has deviations in the hole position, even a slight deviation, it can cause subsequent bolts to be unable to be installed smoothly, or cause the position of the photovoltaic panel after installation to be inaccurate and unstable. Therefore, there are problems of great construction difficulty and low efficiency. Summary of the invention

[0009] In view of this, the present invention provides a photovoltaic module for an existing sound baffle and an installation method, which can realize the installation of the photovoltaic module on the existing sound baffle by constructing a complete installation system for the photovoltaic module, thereby solving the current need for photovoltaic power generation in the field of sound baffles and the problems of high cost and long construction time for replacing new equipment.

[0010] The present invention is achieved in that:

[0011] The present invention provides a photovoltaic assembly with a built sound barrier, comprising a built sound barrier and a photovoltaic assembly, wherein the built sound barrier comprises a row of steel columns installed on both sides of a road, and sound barriers for isolating noise are installed between adjacent steel columns, wherein the photovoltaic assembly comprises a photovoltaic cell panel and connecting cards and fixers on both sides of the photovoltaic cell panel, the photovoltaic cell panel is fixedly installed with the steel columns through multiple groups of fixers on both sides, the connecting cards are fixedly arranged on the left and right sides of the photovoltaic cell panel, respectively, the fixer comprises a clamp and a fixing clamp, the clamp is provided with a screw hole, the fixing clamp comprises a fastening bolt and a stopper block, one end of the stud of the fastening bolt is connected to one side of the stopper block, and a rubber buffer pad is arranged on the other side of the stopper block, the fixing clamp makes one side of the rubber buffer pad of the stopper block contact with the inner side of the steel column through the position of the stud corresponding to the screw hole, and the inner side of the clamp is clamped corresponding to the inner side of the connecting card to fix the photovoltaic cell panel on the steel column.

[0012] On the basis of the above technical solution, the photovoltaic assembly with built sound barrier of the present invention can also be improved as follows:

[0013] Wherein, the clamp is a C-shaped clamp, and the two sides of the photovoltaic panel are fixed to the steel column by two groups of the fixing devices respectively, and the upper and lower ends of the side wall of the C-shaped clamp are provided with T-shaped slots, and a lateral support calibration member is connected between the two groups of C-shaped clamps located on the same side of the photovoltaic panel through the T-shaped slot, and the upper and lower ends of the lateral support calibration member are both T-shaped blocks adapted to the T-shaped slots.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a T-shaped slot for installing the lateral support calibration member, the lateral support calibration member can provide support force in the vertical direction. Since the photovoltaic panel has a certain weight, especially when the length of the photovoltaic panel is greater than the conventional size, the lateral support calibration member can share the weight by connecting the upper and lower adjacent C-shaped clips, thereby reducing the vertical pressure borne by the C-shaped clips; and the lateral support calibration member plays a key role in standardizing the installation alignment of the photovoltaic panel. During the installation process, after the upper and lower C-shaped clips on one side of the photovoltaic panel are connected by the lateral support calibration member, the position of this side of the photovoltaic panel is fixed on a standard plane. Because the lengths of the lateral support calibration members on both sides are the same, it is possible to ensure that the distance between the upper and lower C-shaped clips remains consistent, so that the installation position of the photovoltaic panel on this side is standardized. When multiple groups of photovoltaic panels are installed between adjacent steel columns, this alignment method can ensure that the edges of each photovoltaic panel are on the same straight line, achieving a uniform installation effect.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by arranging shock-absorbing gaskets to further buffer vibrations, the steel column is prevented from being subjected to vibrations transmitted to the fixer and causing the C-shaped clamp to loosen; by arranging multiple groups of grooves on the connecting card to cooperate with the protrusions on the C-shaped clamp to engage with each other, precise positioning is provided for the installation of the photovoltaic panel, and compared with the planar contact, this engaging method concentrates the pressure on the contact part of the protrusion and the groove, forming a mechanical interlocking structure, which can effectively resist external forces, prevent the photovoltaic panel from being displaced on the inner side of the C-shaped clamp, and significantly enhance its wind resistance.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] Embodiment 1:

[0041] like Figure 1-4As shown, it is a first embodiment of a photovoltaic assembly with a built sound barrier provided by the present invention. In this embodiment, it includes a built sound barrier 1 and a photovoltaic assembly 10. The built sound barrier 1 includes a row of steel columns 2 installed on both sides of the road. Sound barriers 3 for isolating noise are installed between adjacent steel columns 2. Among them, the photovoltaic assembly 10 includes a photovoltaic panel 4 and connection cards 12 and a fixture 11 on both sides of the photovoltaic panel 4. The photovoltaic panel 4 is fixedly installed with the steel column 2 through multiple groups of fixtures 11 on both sides. The connection cards 12 are respectively fixedly arranged on the left and right sides of the photovoltaic panel 4. On the right side, the fixer 11 includes a clamp 13 and a fixing clamp 14. The clamp 13 is provided with a screw hole. The fixing clamp 14 includes a fastening bolt 15 and a stop pressure block 16. One end of the stud of the fastening bolt 15 is connected to one side of the stop pressure block 16. A rubber buffer pad 17 is provided on the other side of the stop pressure block 16. The fixing clamp 14 makes one side of the rubber buffer pad 17 of the stop pressure block 16 contact with the inner side of the steel column 2 through the position of the screw hole corresponding to the stud, and the inner side of the clamp 13 is clamped corresponding to the inner side of the connecting card 12, so as to fix the photovoltaic panel 4 on the steel column 2.

[0042] Among them, in the above technical scheme, the clamp 13 is a C-shaped clamp, and the two sides of the photovoltaic panel 4 are fixed to the steel column 2 by two groups of fixers 11 respectively, and T-shaped slots 18 are provided at the upper and lower ends of the side wall of the C-shaped clamp. A lateral support calibration member 19 is connected between the two groups of C-shaped clamps located on the same side of the photovoltaic panel 4 through the T-shaped slot 18, and the upper and lower ends of the lateral support calibration member 19 are both T-shaped blocks that are adapted to the T-shaped slot 18.

[0043] Furthermore, in the above technical solution, multiple groups of photovoltaic panels 4 are fixedly installed between adjacent steel columns 2 through multiple groups of fixers 11, and the C-shaped clamp located at the bottom position is connected to the support rod 20 through the T-shaped slot 18 at the lower end to contact the bottom end of the steel column 2 with the ground.

[0044] Furthermore, in the above technical solution, a shock-absorbing gasket 21 is provided on the side where the connecting card 12 contacts the steel column 2, and the shock-absorbing gasket 21 is bonded and fixed to the connecting card 12. A plurality of groups of grooves 23 for limiting and fixing are provided on the surface where the connecting card 12 contacts the C-shaped clip, and a protrusion 22 matching the groove 23 is provided on the surface where the connecting card 12 contacts the C-shaped clip.

[0045] Among them, when the protrusion 22 of the C-shaped clamp cooperates with the groove 23 of the connecting card 12, a mechanical interlocking structure is formed, which can effectively resist external forces and prevent the photovoltaic panel 4 from lateral displacement in the C-shaped clamp; for example, when subjected to external forces in a large horizontal direction such as wind loads, the traditional planar contact method will cause the photovoltaic panel 4 to slide in the C-shaped clamp, and this interlocking design can limit the horizontal movement of the photovoltaic panel 4 through a blocking effect, so that the photovoltaic panel 4 is more firmly fixed in the C-shaped clamp.

[0046] Furthermore, in the above technical solution, an anti-retraction sleeve 5 is installed on the side of the fixer 11 close to the fastening bolt 15, two groups of dovetail tenon blocks 6 are arranged on the surface of the C-shaped clamp facing outward, and an adaptive dovetail groove 51 is opened at the position corresponding to the dovetail tenon block 6 on the anti-retraction sleeve 5, a U-shaped groove 52 is opened at one end of the anti-retraction sleeve 5, and a shock-absorbing anti-retraction rubber plug 53 is arranged on the inner side of the U-shaped groove 52.

[0047] Furthermore, in the above technical solution, the surface of the shock-absorbing and anti-retreat rubber plug 53 is provided with a protrusion, which is used to contact the surface of the fastening bolt 15 to play a role of fixing and preventing retreat. The protrusion is a granular protrusion, and the height dimension is set between 2 and 5 mm, and the width is between 1 and 3 mm. The spacing between adjacent granular protrusions is selected according to the diameter of the fastening bolt 15, usually 3 to 8 mm.

[0048] like Figure 1 ,6, further, in the above technical solution, the connection card 12 is fixedly connected to the photovoltaic panel 4 through the anti-detachment connection member 7, and the anti-detachment connection member 7 includes a fixed pull rod 71, a clamping member 72 at both ends, and a tension spring 73. A plurality of connection holes are symmetrically opened at both ends of the clamping member 72, and the connection holes are used to fix the fixed pull rod 71. A clamping mechanism is arranged in the middle of the fixed pull rod 71. The fixed pull rod 71 includes a first buckling end 711 and a second buckling end 712. A limited block is arranged at one end of the first buckling end 711, and a boss 71 is arranged at the other end of the first buckling end 711. 11. A convex ring 7112 is provided on the side wall of the boss 7111; a limiting block is provided at one end of the second buckling end 712, a cavity 7121 is provided at the other end of the second buckling end 712, and a concave ring 7122 is provided on the inner wall of the cavity 7121. The buckle mechanism includes the boss 7111, the convex ring 7112, the cavity 7121 and the concave ring 7122; one end of the connecting card 12 is fixedly connected to the clamping piece 72 at one end, one end of the photovoltaic panel 4 is fixedly connected to the clamping piece 72 at the other end, and the middle parts of the clamping pieces 72 on both sides are fixedly connected to the two ends of the tension spring 73 respectively.

[0049] When the built sound barrier 1 vibrates, the tension spring 73 will undergo elastic deformation, and the elastic force generated by it resists the transmission of vibration. This elastic deformation absorbs part of the vibration energy and changes the stiffness characteristics of the connection structure. According to the equivalent stiffness formula of series springs, the tension spring 73 is used to reduce the equivalent stiffness of the entire anti-detachment connector 7. Since the vibration frequency is proportional to the square root of the stiffness, the vibration frequency of the photovoltaic panel 4 is reduced. Therefore, the tension spring 73 is used to make the vibration frequency transmitted to the photovoltaic panel 4 different from the vibration frequency of the sound barrier 3, thereby effectively avoiding the occurrence of resonance, making the installation of the photovoltaic panel 4 more stable and preventing it from falling off.

A spring 57 is sleeved on the outer side of the movable coupling 56. An inclined platform is provided at one end of the card plate 54 close to the opening of the U-shaped groove 52. The inclined platform is used to facilitate guiding when fixed with the fastening bolts 15, so as to facilitate squeezing the card plate 54 to move to both sides. The shock-absorbing and anti-retraction rubber plug 53 is provided at the end of the U-shaped groove 52 and is fixedly connected to the inside of the U-shaped groove 52.
