Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation equipment, and in particular relates to a shockproof structure of a photovoltaic power generation panel. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert light energy into electrical energy. It generates electricity primarily by absorbing sunlight through photovoltaic panels, making it a green, environmentally friendly, and sustainable method of power generation.

[0003] In specific applications, photovoltaic power generation equipment can be arranged in a variety of environments with good lighting conditions, including some environments where there may be large vibrations or jitters. However, the current existing technology for the installation and fixation of photovoltaic equipment is mostly rigid, and there is no vibration filtering structure in between. This also causes the photovoltaic power generation equipment fixed on the vibration surface to shake or vibrate accordingly. Long-term vibration may cause damage to internal devices and loose connections between components, affecting the service life of the equipment. Utility Model Content

[0004] The purpose of the utility model is to address the above-mentioned problems existing in the prior art and to propose a shockproof structure for a photovoltaic power generation panel that can buffer and reduce vibrations in all directions.

[0005] In order to achieve the purpose of innovation, the following technical solutions can be used to achieve the purpose: a shock-proof structure of a photovoltaic power generation panel, including a base and a mounting seat, the mounting seat is fixedly connected to the photovoltaic power generation panel through an angle adjustment structure, the mounting seat is connected to the base, and a shock-absorbing buffer module is detachably arranged between them, and the shock-absorbing buffer module includes a horizontal buffer structure and a vertical buffer structure.

[0006] The photovoltaic panel is mounted on a mounting base, with an angle adjustment structure provided between the mounting base to adjust the inclination angle of the photovoltaic panel. The mounting base is provided on the base, and a shock-absorbing and buffering module is provided between the base and the mounting base to filter vibrations between the mounting base and the base, thereby reducing the shaking of the photovoltaic panel and avoiding loose connections between the components of the photovoltaic panel that may be caused by shaking, thereby increasing the service life and providing conditions for installing photovoltaic panels in unstable environments. Specifically, the shock-absorbing and buffering module includes a horizontal buffer structure and a vertical buffer structure, which can buffer vibrations in the horizontal and vertical directions to achieve the effect of shock absorption in all directions; and the shock-absorbing and buffering module and the base are detachably connected, which is convenient for loading and unloading and subsequent maintenance.

[0007] In the above-mentioned shockproof structure of the photovoltaic panel, the horizontal buffer structure includes a circular buffer cylinder, a circular buffer seat and a buffer spring. The buffer cylinder can be detachably inserted into a circular matching slot. The matching slot is opened at the upper end of the base, and the inner diameter is adapted to the outer diameter of the buffer cylinder. The buffer seat can be arbitrarily slid horizontally in the buffer cylinder, and a number of buffer springs are connected between the buffer seat and the buffer cylinder.

[0008] A matching slot is provided on the upper end surface of the base, and the buffer tube can be slidably inserted into the matching slot to form a detachable connection, which is convenient for loading and unloading and subsequent maintenance. The buffer seat is arranged in the buffer tube, and the buffer seat is attached to the inner bottom surface of the buffer tube and can slide arbitrarily in the horizontal direction. A buffer spring is arranged between the side surface of the buffer seat and the side surface of the buffer tube. Through the compression and stretching of the buffer spring, the horizontal movement of the buffer seat is elastically blocked, thereby achieving the effect of filtering the vibration in the horizontal direction.

[0009] In the above-mentioned shockproof structure of the photovoltaic power generation panel, at least three buffer springs are evenly distributed circumferentially between the buffer seat and the buffer cylinder, and the two ends of the buffer spring are respectively fixed to the inner wall of the buffer cylinder and the outer wall of the buffer seat.

[0010] The buffer spring is arranged horizontally between the buffer tube and the buffer seat, and its two ends are fixed to the sides of the buffer tube and the buffer seat respectively. The fixing method can be in the form of gluing, or the spring end can be fixed by screwing screws horizontally into the buffer tube or the buffer seat.

[0011] In the above-mentioned shockproof structure of the photovoltaic panel, the vertical buffer structure includes a limit cylinder, a limit column and a compression spring. The limit cylinder is fixed to the upper end of the buffer seat, and the limit column is vertically fixed to the lower side of the mounting seat. The limit column is positioned opposite to the limit cylinder, and the limit column is inserted into the limit cylinder. The compression spring is compressed between the inner bottom surface of the limit cylinder and the lower end surface of the limit column.

[0012] The limiting column is fixed on the lower surface of the mounting seat, the limiting column is inserted into the limiting cylinder, and a compression spring is arranged between the limiting column and the limiting cylinder, and the elastic force of the compression spring achieves a buffering effect on vertical vibration.

[0013] In the above-mentioned anti-vibration structure of the photovoltaic power generation panel, the shock-absorbing and buffering modules are provided in four groups, which are evenly distributed between the base and the mounting seat.

[0014] There are 4 groups of shock-absorbing and buffering modules evenly distributed, that is, shock-absorbing and buffering modules are set at the four corners, which makes the support force of the mounting seat more uniform and the buffering effect better.

[0015] In the above-mentioned anti-vibration structure of the photovoltaic power generation panel, the mounting seat is in a cap shape, the mounting seat covers the base, and a first offset allowable space exists between the side wall of the mounting seat and the side wall of the base.

[0016] The mounting seat is cap-shaped and covers the base. From the horizontal cross-section, the mounting seat is larger than the base. There is a first offset allowable space in the horizontal direction between the base and the mounting seat, which ensures that the mounting seat can be offset to a certain extent in the horizontal direction relative to the base to ensure that the horizontal buffer structure fully exerts the buffering and shock-absorbing function in the horizontal direction. Not only that, it can also prevent rainwater and the like from entering between the mounting seat and the base, thereby extending the service life of the shock-absorbing and buffering module.

[0017] In the above-mentioned shockproof structure of the photovoltaic panel, at least 4 groups of positioning and anti-slip structures are evenly distributed circumferentially between the base and the side wall of the mounting seat. The positioning and anti-slip structures include positioning through holes, connecting screw holes and positioning bolts. The positioning through holes are opened on the side walls of the mounting seat, and the connecting screw holes are opened on the outer wall of the base. The positions of the connecting screw holes and the positioning through holes correspond to each other. The positioning bolts pass through the positioning through holes and are connected to the connecting screw holes. A washer is provided between the positioning bolts and the positioning through holes.

[0018] The positioning and anti-slip structure is used to limit the mounting seat cover to the base to prevent the mounting seat from being lifted and detached from the top of the base. It has a limiting effect in the vertical direction. At the same time, in the horizontal direction, when the shock-absorbing and buffering module fails and the horizontal displacement of the mounting seat relative to the base is too large, the positioning and anti-slip structure can intervene to block the further displacement of the mounting seat and limit the horizontal displacement of the mounting seat relative to the base to a certain range. It has a limiting effect in the horizontal direction. Specifically, the positioning bolt passes through the positioning through-hole on the side of the mounting seat and is connected to the base. A washer is provided between the positioning bolt and the positioning through-hole to prevent the bolt head of the positioning bolt from passing through the positioning through-hole. The positioning bolt and the upper and lower side walls of the positioning through-hole form a limiting range in the vertical direction. The positioning bolt and the side walls of the positioning through-hole, as well as the washer and the outer periphery of the positioning through-hole, form a limiting range in the horizontal direction.

[0019] In the above-mentioned shock-proof structure of the photovoltaic panel, the inner diameter of the positioning through hole is larger than the outer diameter of the screw of the positioning bolt, the outer diameter of the washer is larger than the inner diameter of the positioning through hole, and there is a second offset allowable space between the limiting bolt and washer and the outer wall of the mounting seat, and a rubber sleeve is provided on the inner wall of the positioning through hole.

[0020] The size of the positioning through hole is larger than the screw size of the positioning bolt, ensuring that the positioning bolt has a range of movement in the positioning through hole. The size of the washer is larger than the positioning through hole, ensuring that the washer will not pass through the positioning through hole. A rubber sleeve is provided on the inner wall of the positioning through hole to reduce the wear of the positioning bolt. There is a distance between the washer and the outer wall of the mounting seat, and there is a second offset allowable space, which ensures that the mounting seat has an offset range of horizontal movement.

[0021] In the above-mentioned shock-proof structure of the photovoltaic panel, the angle adjustment structure includes two strip plates respectively hinged to the two sides of the mounting seat, and a locking groove is opened in the strip plates along the length direction. The lower end of the photovoltaic panel is hinged to the mounting seat, and locking screws are fixed laterally on both sides. The locking screws are inserted into the locking grooves and are locked and fixed by locking nuts.

[0022] The strip plate is hinged to the side of the mounting base, and a locking screw is fixed to the side of the photovoltaic panel. The locking screw slides into the locking groove of the strip plate, and the locking nut engages with the locking screw. When tightened, the strip plate and the photovoltaic panel are locked and fixed. By adjusting the fixed position on the locking groove, the angle of the photovoltaic panel can be adjusted. There are two strip plates, one on each side, which are evenly stressed and more stable.

[0023] In the above-mentioned earthquake-proof structure of the photovoltaic panel, the strip plate is L-shaped, including a short section and a long section connected as one piece, the outer end of the short section is hinged to the mounting seat, and the shape of the locking groove is adapted to the shape of the strip plate.

[0024] The strip plate is L-shaped, and correspondingly, the locking groove is also L-shaped. One end of the short section of the strip plate is hinged to the mounting seat, and the other end of the long section and the short section are fixed integrally. When the angle between the photovoltaic panel and the mounting seat is small, the locking screw is locked on the short section. At this time, due to the angle between the short section and the long section, it is equivalent to the long section of the strip plate being horizontally bent, which controls the length of the strip plate that is warped upward. When the angle between the photovoltaic panel and the mounting seat is large, the locking screw mainly cooperates with the locking groove on the long section.

[0025] Compared with the prior art, the utility model has the following advantages:

[0026] 1. The photovoltaic panel is mounted on a mounting base with an angle adjustment structure installed between them to adjust the inclination angle of the photovoltaic panel. The mounting base is installed on the base, and a shock-absorbing buffer module is installed between the base and the mounting base to filter vibrations between the mounting base and the base, reducing the shaking of the photovoltaic panel and avoiding loose connections between the components of the photovoltaic panel caused by shaking, thereby increasing the service life and providing conditions for installing photovoltaic panels in unstable environments. Specifically, the shock-absorbing buffer module includes a horizontal buffer structure and a vertical buffer structure, which can buffer vibrations in the horizontal and vertical directions to achieve the effect of shock absorption in all directions; and the shock-absorbing buffer module and the base are detachable, which is convenient for loading and unloading and subsequent maintenance.

[0027] 2. The positioning and anti-slip structure is used to limit the mounting seat cover on the base to prevent the mounting seat from being lifted and detached from the top of the base, and has a limiting effect in the vertical direction. At the same time, in the horizontal direction, when the shock-absorbing and buffering module fails and the horizontal displacement of the mounting seat relative to the base is too large, the positioning and anti-slip structure can intervene to block the further displacement of the mounting seat and limit the horizontal displacement of the mounting seat relative to the base to a certain range, which has a limiting effect in the horizontal direction.

[0028] 3. The strip plate is hinged to the side of the mounting base, and a locking screw is fixed to the side of the photovoltaic panel. The locking screw slides into the locking groove of the strip plate, and the locking nut engages with the locking screw. When tightened, the strip plate and the photovoltaic panel are locked and fixed. By adjusting the fixed position on the locking groove, the angle of the photovoltaic panel can be adjusted. There are two strip plates, one on each side, which are evenly stressed and have a stable structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0036] Specific implementation examples Figure 1-5 As shown, the shock-proof structure of the photovoltaic power generation panel 3 includes a base 1 and a mounting seat 2. The photovoltaic power generation panel 3 is fixedly connected to the mounting seat 2 through an angle adjustment structure 9. The mounting seat 2 is connected to the base 1, and a shock-absorbing buffer module 4 is detachably arranged therebetween. The shock-absorbing buffer module 4 includes a horizontal buffer structure 5 and a vertical buffer structure 6.

[0037] Specifically, the photovoltaic panel 3 is mounted on the mounting base 2, with an angle adjustment structure 9 provided therebetween to adjust the inclination angle of the photovoltaic panel 3. The mounting base 2 is provided on the base 1, and a shock-absorbing and buffering module 4 is provided between the base 1 and the mounting base 2, which can be used to filter the vibration between the mounting base 2 and the base 1, reduce the shaking of the photovoltaic panel 3, and avoid the problem of loose connections between the components of the photovoltaic panel 3 that may be caused by shaking, thereby improving the service life and providing conditions for installing the photovoltaic panel 3 in an unstable environment. Specifically, the shock-absorbing and buffering module 4 includes a horizontal buffer structure 5 and a vertical buffer structure 6, which can buffer vibrations in the horizontal and vertical directions to achieve the effect of shock absorption in all directions; and the shock-absorbing and buffering module 4 and the base 1 are detachably connected, which is convenient for loading and unloading and subsequent maintenance.

[0038] like Figure 2 、 3As shown in Figure 5, the horizontal buffer structure 5 includes a circular buffer tube 51, a circular buffer seat 52 and a buffer spring 53. The buffer tube 51 can be detachably inserted into the circular matching slot 11. The matching slot 11 is opened at the upper end of the base 1, and the inner diameter is adapted to the outer diameter of the buffer tube 51. The buffer seat 52 can be arbitrarily slid horizontally in the buffer tube 51. There are four buffer springs 53 evenly distributed circumferentially between the buffer seat 52 and the buffer tube 51. The two ends of the buffer spring 53 are respectively fixed on the inner wall of the buffer tube 51 and the outer wall of the buffer seat 52.

[0039] Specifically, a matching slot 11 is provided on the upper end surface of the base 1, and the buffer tube 51 can be slidably inserted into the matching slot 11 to form a detachable connection, which is convenient for loading and unloading and subsequent maintenance. The buffer seat 52 is provided in the buffer tube 51, and the buffer seat 52 is attached to the inner bottom surface of the buffer tube 51 and can slide arbitrarily in the horizontal direction. A buffer spring 53 is provided between the side surface of the buffer seat 52 and the side surface of the buffer tube 51. Through the compression and stretching of the buffer spring 53, elastic retardation of the horizontal movement of the buffer seat 52 is achieved, thereby achieving the effect of filtering vibrations in the horizontal direction. The buffer spring 53 is laterally arranged between the buffer tube 51 and the buffer seat 52, and its two ends are respectively fixed to the sides of the buffer tube 51 and the buffer seat 52, and the fixing method is gluing. As an optimization of this embodiment, a wear-resistant layer 54 is provided between the buffer seat 52 and the buffer tube 51, and the wear-resistant layer 54 is fixedly laid on the inner bottom surface of the buffer tube 51.

[0040] like Figure 2 As shown, the shock-absorbing buffer module 4 is provided with 4 groups, evenly distributed between the base 1 and the mounting seat 2, including a limiting cylinder 61, a limiting column 62 and a compression spring 63. The limiting cylinder 61 is fixed to the upper end of the buffer seat 52, and the limiting column 62 is vertically fixed to the lower side of the mounting seat 2. The limiting column 62 is positioned opposite to the limiting cylinder 61, and the limiting column 62 is inserted into the limiting cylinder 61. The compression spring 63 is compressed between the inner bottom surface of the limiting cylinder 61 and the lower end surface of the limiting column 62.

[0041] Specifically, a limiting post 62 is fixed to the lower surface of the mounting base 2 and inserted into a limiting cylinder 61. A compression spring 63 is provided between the limiting post 62 and the limiting cylinder 61. The elastic force of the compression spring 63 provides a buffering effect against vertical vibration. Four groups of shock-absorbing and buffering modules 4 are evenly distributed, that is, shock-absorbing and buffering modules 4 are arranged at the four corners, which provides more uniform support force on the mounting base 2 and better buffering effect.

[0042] like Figure 4As shown, the mounting seat 2 is in a cap shape, and the mounting seat 2 covers the base 1. There is a first offset allowable space 81 between the side wall of the mounting seat 2 and the side wall of the base 1. At least four groups of positioning and anti-slip structures 7 are evenly distributed circumferentially between the base 1 and the side wall of the mounting seat 2. The positioning and anti-slip structures 7 include positioning through holes 71, connecting screw holes 72 and positioning bolts 73. The positioning through holes 71 are opened on the side walls of the mounting seat 2, and the connecting screw holes 72 are opened on the outer side walls of the base 1. The connecting screw holes 72 and the positioning through holes 71 correspond in position. The positioning bolts 73 pass through the positioning through holes 71 and are connected to the connecting screw holes 72. A washer 74 is provided between the positioning bolts 73 and the positioning through holes 71. The inner diameter of the positioning through hole 71 is larger than the outer diameter of the screw of the positioning bolt 73, and the outer diameter of the washer 74 is larger than the inner diameter of the positioning through hole 71. There is a second offset allowable space 82 between the limiting bolt and washer 74 and the outer wall of the mounting seat 2, and a rubber sleeve 75 is provided on the inner wall of the positioning through hole 71.

[0043] Specifically, the mounting seat 2 is in the shape of a cap and covers the base 1. From a horizontal cross-section, the mounting seat 2 is larger than the base 1. There is a first horizontal offset allowable space 81 between the base 1 and the mounting seat 2, which ensures that the mounting seat 2 can be offset to a certain extent in the horizontal direction relative to the base 1, so as to ensure that the horizontal buffer structure 5 can fully exert its buffering and shock-absorbing function in the horizontal direction. Not only that, it can also prevent rainwater and the like from entering between the mounting seat 2 and the base 1, thereby extending the service life of the shock-absorbing and buffering module 4. The positioning and anti-slip structure 7 is used to limit the mounting seat 2 to the base 1 to prevent the mounting seat 2 from being lifted off from the top of the base 1, and has a limiting effect in the vertical direction. At the same time, in the horizontal direction, when the shock-absorbing and buffering module 4 fails and the mounting seat 2 is horizontally offset too much relative to the base 1, the positioning and anti-slip structure 7 can intervene to block the further offset of the mounting seat 2, and limit the horizontal offset of the mounting seat 2 relative to the base 1 to a certain range, and has a limiting effect in the horizontal direction. Specifically, a positioning bolt 73 passes through a positioning hole 71 on the side of the mounting base 2 and is connected to the base 1. A washer 74 is provided between the positioning bolt 73 and the positioning hole 71 to prevent the bolt head of the positioning bolt 73 from passing through the positioning hole 71. A vertical limit range is formed by the positioning bolt 73 and the upper and lower side walls of the positioning hole 71. A horizontal limit range is formed by the positioning bolt 73 and the two side walls of the positioning hole 71, as well as the washer 74 and the outer periphery of the positioning hole 71. The size of the positioning hole 71 is larger than the screw size of the positioning bolt 73, ensuring that the positioning bolt 73 has a range of movement in the positioning hole 71. The size of the washer 74 is larger than the positioning hole 71, ensuring that the washer 74 does not pass through the positioning hole 71. A rubber sleeve 75 is provided on the inner wall of the positioning hole 71 to reduce wear on the positioning bolt 73. There is a distance between the washer 74 and the outer wall of the mounting base 2, providing a second offset allowance space 82, which ensures that the mounting base 2 has a horizontal offset range.

[0044] like Figure 1 As shown, the angle adjustment structure 9 comprises two strips 91 hinged to either side of the mounting base 2. Locking slots 92 are defined along the length of the strips 91. The photovoltaic panel 3 is hinged at its lower end to the mounting base 2, and has locking screws 93 fixed transversely on either side. These locking screws 93 are inserted into the locking slots 92 and secured with locking nuts 94. The strips 91 are L-shaped, comprising an integrally connected short section 95 and a long section 96. The outer end of the short section 95 is hinged to the mounting base 2, and the shape of the locking slots 92 matches that of the strips 91.

[0045] Specifically, the strip plate 91 is hinged to the side of the mounting base 2, and a locking screw 93 is fixed to the side of the photovoltaic panel 3. The locking screw 93 slides into the locking groove 92 of the strip plate 91, and the locking nut 94 engages with the locking screw 93. When tightened, the strip plate 91 and the photovoltaic panel 3 are locked and fixed. By adjusting the fixed position on the locking groove 92, the angle of the photovoltaic panel 3 can be adjusted. There are two strip plates 91, one on each side, which are evenly stressed and more stable. The strip plate 91 is L-shaped, and correspondingly, the locking groove 92 is also L-shaped. One end of the short section 95 of the strip plate 91 is hinged to the mounting base 2, and the long section 96 is fixed integrally with the other end of the short section 95. When the angle between the photovoltaic panel 3 and the mounting base 2 is small, the locking screw 93 is locked on the short section 95. At this time, due to the angle between the short section 95 and the long section 96, it is equivalent to the long section 96 of the strip plate 91 being horizontally bent, which controls the length of the strip plate 91 that is warped upward. When the angle between the photovoltaic panel 3 and the mounting base 2 is large, the locking screw 93 mainly cooperates with the locking groove 92 on the long section 96.

[0046] Specific working principle: During installation, first install the buffer seat 52 into the buffer tube 51, install the buffer spring 53 between the buffer tube 51 and the buffer seat 52 and fix it, then insert the buffer tube 51 into the matching slot hole of the base 1, align the limiting column 62 with the limiting tube 61 and install the mounting seat 2, and insert the positioning bolt 73 from the positioning through hole 71 on the side of the mounting seat 2, screw the positioning bolt 73 into the connecting screw hole 72 of the mounting seat 2 and fix it, and the connection and installation between the mounting seat 2 and the base 1 are completed.

[0047] When adjusting the tilt angle of the photovoltaic power generation panel 3 , loosen the locking nut 94 , rotate the photovoltaic power generation panel 3 to a desired angle, and tighten the locking nut 94 to secure it.

[0048] During operation, when the mounting seat 2 and the base 1 vibrate relative to each other, in the horizontal direction, the buffer seat 52 slides in the buffer tube 51, and the elastic expansion and contraction of the buffer spring 53 buffers and weakens the vibration in the horizontal direction; in the vertical direction, the limiting column 62 slides up and down in the limiting tube 61, and the compression spring 63 between them expands and contracts to buffer and weaken the vibration in the vertical direction.

[0049] In the event of a failure of the shock-absorbing and buffering module 4, when the horizontal offset range of the mounting base 2 is too large, the side wall of the positioning hole 71 is blocked by the positioning bolt 73, forming a protective limit; in the vertical direction, when the mounting base 2 is about to detach upward, the lower side wall of the positioning hole 71 is blocked by the positioning bolt 73, preventing the mounting base 2 from detaching upward.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
