[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0034] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.
[0035] Please refer to Figures 1 to 18 The embodiment of the present application discloses a photovoltaic support 100 for carrying a photovoltaic module 200. The photovoltaic module 200 may be a monocrystalline silicon photovoltaic module, a polycrystalline silicon photovoltaic module, a thin-film photovoltaic module, etc. The disclosed photovoltaic support 100 may include a base 110, an adjustment support 120, and a control member 130. The base 110 is the structural foundation of the photovoltaic support 100 and is used to connect with a bearing object such as a roof, a wall, a concrete pile foundation, etc. to support the photovoltaic module 200.
[0036] During the specific installation process of the photovoltaic bracket 100, Figures 1 to 6 As shown, one end of the adjusting bracket 120 is connected to the photovoltaic module 200, and the adjusting bracket 120 can be connected to the backlight side of the photovoltaic module 200. The specific connection method can be bonding, clamping, bolt connection, etc. The other end of the adjusting bracket 120 is rotatably connected to the base 110. The adjusting bracket 120 and the base 110 can be connected by a rotating shaft to achieve relative rotation, and a flexible connector can be set between the adjusting bracket 120 and the base 110 to achieve relative rotation, so that the adjusting bracket 120 can adjust the inclination of the photovoltaic module 200 by rotation. It should be noted that the inclination angle is the angle between the panel surface of the photovoltaic module 200 and the horizontal plane. Reasonable selection of the inclination angle of the photovoltaic module 200 can maximize the use of solar energy and improve power generation efficiency. The inclination angle of the photovoltaic module 200 depends on factors such as geographical location, season, climate conditions, and usage requirements.
[0037] The rotation of the adjusting bracket 120 relative to the base 110 can adjust the inclination angle of the photovoltaic assembly 200, but the timing of the relative rotation of the adjusting bracket 120 and the base 110 needs to be controlled. Specifically, Figure 3As shown in FIG8 , the control member 130 is disposed on the base 110 and is slidably connected to the base 110 . The control member 130 may be a buckle, a gear, etc. The control member 130 has a first position and a second position and can be switched between the first position and the second position by sliding.
[0038] When the control member 130 is in the first position (eg Figure 7 ), the control member 130 and the adjustment bracket 120 are in a locked state, and the rotation state of the adjustment bracket 120 can be limited by a snap connection so that the adjustment bracket 120 and the base 110 are relatively fixed; when the control member 130 slides from the first position to the second position (as shown in FIG. Figure 8 As shown), the control member 130 and the adjustment bracket 120 are in an unlocked state and no longer restrict and interfere with each other, so that the adjustment bracket 120 and the base 110 can rotate relative to each other.
[0039] Corresponding to specific usage scenarios, when the inclination angle of the photovoltaic component 200 needs to be adjusted, the control component 130 can be slid to the second position first. At this time, the adjustment bracket 120 and the base 110 can rotate relative to each other, and the inclination angle of the photovoltaic component 200 can be flexibly adjusted. After the inclination angle is adjusted, the control component 130 can be slid from the second position to the first position, so that the control component 130 and the adjustment bracket 120 are in a locked state. At this time, the adjustment bracket 120 and the base 110 are relatively fixed, so that the inclination angle of the photovoltaic component 200 is fixed.
[0040] From the above, it can be seen that the photovoltaic bracket 100 disclosed in the embodiment of the present application improves the relevant technology. By sliding the control member 130 between the first position and the second position, the inclination angle of the photovoltaic component 200 can be adjusted or locked without the aid of other tools. The operation is simple, thereby improving the efficiency of the inclination angle adjustment of the photovoltaic component 200.
[0041] like Figures 3 to 6 As shown, a first rack 122 is provided at the end of the adjustment bracket 120 close to the base 110, and a second rack 131 is provided at the control member 130. When the control member 130 is in the first position, the first rack 122 is meshed with the second rack 131. Under the limiting action of the second rack 131, the control member 130 and the adjustment bracket 120 are in the locked state, so that the adjustment bracket 120 and the base 110 are relatively fixed, and the inclination angle of the photovoltaic component 200 can be maintained fixed; when the control member 130 slides from the first position to the second position, the first rack 122 is separated from the second rack 131, so that the control member 130 and the adjustment bracket 120 are in the unlocked state, the adjustment bracket 120 and the base 110 can rotate relative to each other, and the inclination angle of the photovoltaic component 200 can be adjusted.
[0042] like Figures 3 to 6As shown, the above-mentioned base 110 may include a accommodating cavity 1121 and a shaft rod 1122 arranged in the accommodating cavity 1121, and the two ends of the shaft rod 1122 are respectively connected to the two opposite cavity walls of the accommodating cavity 1121, and the end of the adjusting bracket 120 close to the base 110 is provided with an axial hole 121, the end of the adjusting bracket 120 is arc-shaped, and is provided with the above-mentioned first rack 122, the shaft rod 1122 is passed through the axial hole 121, so that the adjusting bracket 120 is rotatably connected to the base 110, the first rack 122 extends into the accommodating cavity 1121 along with the end of the adjusting bracket 120, and the second rack 131 also extends into the accommodating cavity 1121, and meshes with the first rack 122.
[0043] Furthermore, if Figure 7 , Figure 8 , Fig.11 As shown, the control member 130 may include a pressing portion 132, a sliding shaft 133 and a locking portion 134. The pressing portion 132 is connected to the end of the sliding shaft 133, and the locking portion 134 is connected to the side of the sliding shaft 133. The pressing portion 132, the sliding shaft 133 and the locking portion 134 may be an integrated structure, or may be made separately and then assembled together by bonding, bolting, etc. The cavity wall of the accommodating cavity 1121 is provided with a through hole 1123, the sliding shaft 133 is penetrated through the through hole 1123 and is slidably connected to the through hole 1123, at least part of the locking portion 134 and the sliding shaft 133 extends into the accommodating cavity 1121, and at least part of the pressing portion 132 extends out of the accommodating cavity 1121 and is slidably connected to the through hole 1123. The pressing portion 132 may be a button, and the user may slide the control member 130 from the first position to the second position by pressing it.
[0044] The surface of the locking portion 134 facing the adjusting bracket 120 is provided with the second rack 131. When the sliding shaft 133 slides relative to the through hole 1123, the first rack 122 is meshed with or separated from the second rack 131. Specifically, when the control member 130 is in the first position, the first rack 122 is meshed with the second rack 131, and the control member 130 and the adjusting bracket 120 are in the locking state, so that the adjusting bracket 120 and the base 110 are relatively fixed; a certain pressure is applied to the pressing portion 132, so that the control member 130 slides from the first position to the second position, at which time the first rack is separated from the second rack 131, and the control member 130 and the adjusting bracket 120 are in the unlocking state, so that the adjusting bracket 120 and the base 110 can rotate relative to each other.
[0045] In an optional embodiment of the present application, Figures 7 and 8As shown, the control member 130 also includes an elastic arm 135, which is connected to the sliding shaft 133 or the locking portion 134. The elastic arm 135 is made of a material with a certain elasticity, such as metal or plastic. A third rack 136 is provided on the surface of the elastic arm 135 facing the adjustment bracket 120. The third rack 136 and the second rack 131 are spaced apart along the axial direction of the sliding shaft 133.
[0046] When the control member 130 is in the first position, the first rack 122 is meshed with the second rack 131, and the control member 130 and the adjusting bracket 120 are in the locking state, so that the adjusting bracket 120 and the base 110 are relatively fixed; a certain pressure is applied to the pressing portion 132 to slide the control member 130 from the first position to the second position, at which time the first rack 122 is separated from the second rack 131, and the third rack 136 is elastically meshed with the first rack 122 instead, and the third rack 136 does not hinder the rotation of the first rack 122 and the adjusting bracket 120. When rotating the adjusting bracket 120, only a slight force needs to be applied to transmit the force to the third rack 136 through the first rack 122. The elastic arm 135 will be elastically deformed by the above-mentioned force, so that the first rack 122 and the third rack 136 can slide relative to each other, thereby rotating the adjusting bracket 120.
[0047] During the adjustment process, the elastic arm 135 and the third rack 136 can apply damping to the adjustment bracket 120 through the first rack 122, thereby improving the controllability of the adjustment process. In addition, the first rack 122 and the third rack 136 both include multiple teeth, and the multiple teeth can also be used as a scale reference for the inclination adjustment process, making the inclination adjustment process more precise.
[0048] For the switching operation of the control member 130 between the first position and the second position, the user may manually apply pressure or traction to the pressing portion 132 to slide the control member 130 relative to the base 110. In order to further improve the convenience of operation, as Figures 7 and 8 As shown, the control member 130 may further include an elastic member 137, which is sleeved on the end of the sliding shaft 133 away from the pressing portion 132, the cavity wall of the accommodating cavity 1121 is provided with a guide groove 1124, the end of the sliding shaft 133 away from the pressing portion 132 extends into the guide groove 1124, and the elastic member 137 is elastically supported between the groove body of the guide groove 1124 and the sliding shaft 133. The elastic member 137 may be a metal spring, a rubber spring, etc.
[0049] By providing the elastic member 137, when the user pushes the pressing portion 132 to make the control member 130 move from the first position (such as Figure 7 ) slide to the second position (such as Figure 8), the elastic member 137 will be in a compressed state. At this time, the first rack 122 and the second rack 131 are separated, and the first rack 122 and the third rack 136 are elastically meshed, so that the adjustment bracket 120 can be rotated to adjust the inclination angle; after the adjustment is completed, the user removes the thrust applied to the pressing portion 132, and the elastic member 137 releases the elastic potential energy, pushing the control member 130 to slide from the second position to the first position. At this time, the first rack 122 and the third rack 136 are separated and re-meshed with the second rack 131, so that the adjustment bracket 120 and the base 110 are relatively fixed. In addition, the meshing of the first rack 122 and the second rack 131 is also beneficial to maintaining the inclination angle of the photovoltaic module 200, and the photovoltaic module 200 and the adjustment bracket 120 are not prone to position displacement.
[0050] The relative rotation of the bracket 120 and the base 110 can adjust the inclination of the photovoltaic assembly 200. In actual use, the azimuth of the photovoltaic assembly 200 also needs to be adjusted. The azimuth refers to the angle between the direction of the photovoltaic assembly 200 and the south direction. Specifically, Figures 9 to 14 As shown, the base 110 may include a base body 111, a rotating base 112 and a fastener 113, the adjusting bracket 120 is rotatably connected to the rotating base 112 to adjust the inclination angle of the photovoltaic assembly 200, and the rotating base 112 is rotatably connected to the base body 111 to adjust the azimuth angle of the photovoltaic assembly 200. The base body 111 and the rotating base 112 may be coaxially arranged and relatively rotatable around a common axis direction.
[0051] The fastener 113 is connected to the base body 111 and the rotating seat 112 respectively. When the fastener 113 is in a locked state, the base body 111 and the rotating seat 112 are relatively fixed. When the fastener 113 is in a loose state, the base body 111 and the rotating seat 112 can rotate relatively.
[0052] The fastener 113 may be a lock buckle, a locking nut 1131, etc. Taking the locking nut 1131 as an example, a thread 1111 may be provided on the side of the base body 111, and a flange 1125 may be provided on the edge of the rotating seat 112 close to the base body 111, and the flange 1125 may extend into the interior of the locking nut 1131. During actual installation, the locking nut 1131 is screwed together with the base body 111 to a locked state, and under the constraint of the locking nut 1131, the base body 111 and the rotating seat 112 may be relatively fixed; when the azimuth angle of the photovoltaic module 200 needs to be adjusted, the base body 111 and the rotating seat 112 may be separated from each other by simply loosening the locking nut 1131.
[0053] With the above-mentioned locking nut 1131, if the locking nut 1131 is over-screwed out, it is easy to fall off the base body 111, causing unnecessary losses. Based on the above situation, the thread 1111 on the side of the base body 111 can be divided into a first sub-thread 1111a and a second sub-thread 1111b, and along the screwing direction of the locking nut 1131, the first sub-thread 1111a and the second sub-thread 1111b are arranged at intervals.
[0054] When used, the locking nut 1131 is screwed into the first sub-thread 1111a of the base body 111, and passes through the non-threaded area 1111 between the first sub-thread 1111a and the second sub-thread 1111b (such as Fig.13 As shown), screw it into the second sub-thread 1111b (as shown Fig.12 As shown in the figure, the rotating seat 112 is locked on the base body 111. When the azimuth angle of the photovoltaic module 200 needs to be adjusted, the locking nut 1131 is screwed upwards so that the locking nut 1131 enters the non-threaded area 1111 and cannot be screwed upwards further, thereby preventing the locking nut 1131 from falling off, and further preventing the photovoltaic module 200 from being separated from the base body 111, thereby ensuring safety.
[0055] like Figure 12 to Figure 14 As shown, the surface of the base body 111 that is in contact with the rotating seat 112 is provided with a first tooth ring 1112, and the surface of the rotating seat 112 that is in contact with the base body 111 is provided with a second tooth ring 1126. The first tooth ring 1112 is meshed with the second tooth ring 1126, thereby increasing the friction between the base body 111 and the rotating seat 112 to avoid relative rotation between the base body 111 and the rotating seat 112 when in a locked state, thereby improving the stability of the photovoltaic bracket 100.
[0056] Please refer to Figures 1 to 18 The embodiment of the present application also discloses a photovoltaic system, including a photovoltaic assembly 200 and the above-mentioned photovoltaic bracket 100, and an adjustment bracket 120 is connected to the photovoltaic assembly 200. By adopting the above-mentioned photovoltaic bracket 100, the inclination angle of the photovoltaic assembly 200 can be adjusted or locked by sliding the control member 130 between the first position and the second position, without the need for other tools, and the operation is simple, thereby improving the efficiency of the inclination angle adjustment of the photovoltaic assembly 200.
[0057] Regarding the specific connection method between the adjustment bracket 120 and the photovoltaic assembly 200, in an optional embodiment of the present application, as follows: Figures 15 to 18As shown, a slider 123 can be provided on the side of the adjustment bracket 120 facing away from the base 110, and a slide groove 210 can be provided on the surface of the photovoltaic module 200 for connecting with the adjustment bracket 120. The slider 123 is inserted into the slide groove 210 and engaged with the slide groove 210, so that the adjustment bracket 120 and the photovoltaic module 200 can be quickly installed. When disassembling the photovoltaic module 200, it is only necessary to take the slider 123 out of the slide groove 210.
[0058] like Figure 17 to Figure 18 As shown, in order to further improve the reliability of the connection between the photovoltaic component 200 and the adjustment bracket 120, a first elastic buckle 220 can be provided at the edge of the slide groove 210, and a second elastic buckle 124 can be provided at the edge of the slider 123. When the slider 123 extends into the slide groove 210, the first elastic buckle 220 is engaged with the second elastic buckle 124. The above double protection can prevent the photovoltaic component 200 from being separated from the adjustment bracket 120.
[0059] like Fig.16 As shown, since the photovoltaic assembly 200 will be equipped with more wire harnesses, in order to reduce the shaking and bending of the wire harnesses and improve the aesthetics of the photovoltaic assembly 200, the photovoltaic bracket 100 may also include a wire harness storage portion 125, which is connected to the adjustment bracket 120 and is used to store the wire harness of the photovoltaic assembly 200. The wire harness storage portion 125 may be a storage groove, a wire hole, etc. The wire harness storage portion 125 and the adjustment bracket 120 may be an integrated structure, or they may be made separately and then assembled together by welding, bolting, etc.
[0060] The above embodiments of the present application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
[0061] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
