A splicing mechanism for fixing photovoltaic components and a photovoltaic curtain wall

Abstract

The present invention discloses a splicing mechanism and a photovoltaic curtain wall for fixing photovoltaic modules, which relate to the technical field of photovoltaic modules, including a plurality of photovoltaic panels, and also including a gap control splicing mechanism for connecting the photovoltaic panels, and an automatic adjustment mechanism for controlling the movement of the gap control splicing mechanism according to the temperature change between the photovoltaic panels. In the initial installation state, there is no restriction on the gap between the photovoltaic panels. Therefore, when installing adjacent photovoltaic panels, the probability of edge touching during the splicing process is greatly reduced due to the large installation gap left. When the installation is completed, the gap between the photovoltaic panels will be automatically adjusted. The gap of the photovoltaic panels can be automatically adjusted through the assembly. First, it can avoid the photovoltaic panels from being affected by the temperature and causing thermal expansion, which causes the edges to conflict with each other. Secondly, when the gap is increased, it can promote gas circulation, thereby improving the heat dissipation of the photovoltaic panels.

Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a splicing mechanism for fixing photovoltaic modules and a photovoltaic curtain wall. Background Art

[0002] Photovoltaic curtain wall is to use special resin to stick solar cells on glass, embed them between two pieces of glass, and convert light energy into electricity through batteries. It combines photovoltaic power generation technology and curtain wall technology, makes full use of the surface and space of the building, and converts the solar energy that traditional curtain walls try to shield outside the building into electricity that is beneficial to people. The biggest feature is that it has the functions of ventilation, environmental protection, and energy saving, which saves the consumption of precious fossil energy on the earth and reduces pollution to the environment. At the same time, it provides a new aesthetic decorative effect for modern buildings. Usually, photovoltaic curtain walls are made up of multiple photovoltaic panels.

[0003] However, when splicing the photovoltaic wall, attention should be paid to the splicing gap. In order to prevent the hot spot effect caused by thermal expansion and contraction, it is recommended to fill the splicing gap with moisture-proof materials (such as silicone grease, foam, etc.) and leave a certain gap between the components. If the gap is too small, the squeeze and collision of the panels may cause damage to the edge of the photovoltaic panel. If the gap is too large, rainwater and dust will penetrate. Therefore, there must be a gap between the photovoltaic panels, but the gap cannot be too large. Moreover, the gap will change during use. According to the above description, there are certain gap requirements for photovoltaic panels when splicing. However, if the gap is small, it will increase the difficulty of installation when splicing (the smaller the splicing gap, the greater the probability of edge touching during splicing). For this reason, it is not easy to splice the existing photovoltaic panels, which makes the splicing more difficult. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. The embodiments of the present invention provide a splicing mechanism and a photovoltaic curtain wall for fixing photovoltaic modules, so as to solve the technical problems that the existing photovoltaic modules are inconvenient to control the gap between photovoltaic panels when splicing, and the installation is difficult due to the small gap.

[0005] The embodiment of the present invention adopts the following technical scheme: a splicing mechanism for fixing photovoltaic components and a photovoltaic curtain wall, including a plurality of photovoltaic panels, and also including a gap-controlled splicing mechanism for connecting the photovoltaic panels, and an automatic adjustment mechanism for controlling the movement of the gap-controlled splicing mechanism according to temperature changes between the photovoltaic panels. The gap-controlled splicing mechanism includes a guide installation component and a regulating component, and the guide installation component is divided into a necking portion and an insertion portion from top to bottom, and a guide portion is arranged on the outside of the necking portion. Side connecting blocks are arranged on the photovoltaic panels at both ends of the photovoltaic curtain wall, and slide grooves are arranged in the side connecting blocks.

[0006] Furthermore, the diameter of the necking portion is larger than that of the inserting portion, and the connecting portion between the necking portion and the inserting portion is arc-shaped, while the inner diameter of the necking portion gradually decreases, and through grooves are provided at the inserting portion and the necking portion.

[0007] Further, the regulating component includes a connecting sliding block, the connecting sliding block is located in the guide installation component, control rods are rotatably connected on both sides of the sliding connecting block, and the end of the control rod is connected to a connecting block, a connecting frame is provided on the surface of the photovoltaic panel, a sliding groove is provided in the connecting frame, and the sliding groove is divided into a first part and a second part, a movable block is provided in the connecting block, and the movable block is located in the sliding groove, wherein a part of the sliding grooves is provided with a plurality of spring limit blocks, a groove is provided on the side wall of the spring limit block, and a movable limit rod is provided in the groove for limiting the position of the spring limit block, a movable limit block is provided on the inner side of the movable block, the movable limit block passes through the connecting frame, and a resisting telescopic rod is provided on one side of the bottom end of the movable limit block, and the contact surface between the movable end of the resisting telescopic rod and the movable limit is an inclined surface, a hydraulic telescopic rod is installed on the surface of the guide installation component, and the hydraulic telescopic rod is located between the two photovoltaic panels, the hydraulic telescopic rod and the resisting telescopic rod are connected by a connecting pipe, and a buffer block is provided below the connecting sliding block.

[0008] Furthermore, the end surface of the movable block is an arc surface, and in the initial state, the height of the movable limit block is higher than the height of the arc surface of the movable block.

[0009] Furthermore, one side surface of the spring limit block is a curved surface.

[0010] Furthermore, the end of the control rod is in an arc hook shape, and the end of the control rod is made of a plastic material.

[0011] Furthermore, the automatic adjustment mechanism includes a fixed end, the fixed end is located in the guide portion, a limiting block is arranged inside the fixed end, a movable end is arranged above the limiting block, and the limiting block and the movable end are connected by a spring.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] First, when the photovoltaic panels are spliced ​​by the gap control splicing mechanism, it can be roughly divided into two parts. The first is the preliminary splicing, and there is no need to control the gap between the photovoltaic panels. Therefore, when the gap splicing mechanism is installed, the installation difficulty is low, and the collision phenomenon between the gaps of the photovoltaic panels can be greatly reduced, thereby improving the installation safety. Secondly, when the guide installation components are plugged into each other, since the insertion part is much smaller than the necking part, the guide installation components can be inserted more conveniently. Subsequently, during the insertion process, the gap between the photovoltaic panels will be gradually reduced by the gap control splicing mechanism until it contacts the hydraulic telescopic rod (the hydraulic telescopic rod). The retracted length of the retracted rod is the width of the gap reserved for splicing) so as to automatically adjust the gap between the two photovoltaic panels without manual measurement and processing. Moreover, when the gap control splicing mechanism is used to control the gap between the photovoltaic panels, the automatic adjustment of the gap between the photovoltaic panels utilizes the weight of the upper photovoltaic panels. No additional power source is required to drive the mechanism, which makes the operation simple and effective, and greatly improves the installation efficiency. Secondly, during use, in different curtain walls, the height of the photovoltaic panels composed therein will change. Although the height of the guide installation assembly remains unchanged, the splicing mechanism will not affect the use of the photovoltaic panels, thereby improving the application range of the splicing mechanism.

[0014] Secondly, in the later use, the photovoltaic panels may change in size due to thermal expansion and contraction. For this reason, the gap between the photovoltaic panels can be automatically controlled through the cooperation of the gap control splicing mechanism and the automatic adjustment mechanism, thereby increasing the gap between the photovoltaic panels. After the gap between the photovoltaic panels is changed (due to the existence of the gap, even if the photovoltaic panels change in size due to thermal expansion and contraction, the photovoltaic panels will not touch each other, thereby improving safety. Secondly, when the gap is increased, efficient heat dissipation between the photovoltaic panels is facilitated), the adjustment performance of the automatic adjustment mechanism is also affected by the temperature of the photovoltaic panels. The higher the temperature of the photovoltaic panels, the larger the gap is adjusted.

[0015] To summarize, when the photovoltaic panels are spliced ​​using this component, there is no restriction on the gap between the photovoltaic panels in the initial installation state. Therefore, when adjacent photovoltaic panels are installed, the larger installation gap greatly reduces the probability of edge touching during the splicing process. When the installation is completed, the gap between the photovoltaic panels will be automatically adjusted to ensure that the gap between the photovoltaic panels is within a safe range (that is, the gap is large in the initial state and small in the installation completed state). At the same time, during subsequent use, the gap between the photovoltaic panels can be automatically adjusted through this component. First, it can avoid thermal expansion of the photovoltaic panels due to the influence of temperature, which causes the edges to conflict with each other. Secondly, when the gap is increased, it can promote gas circulation, thereby improving the heat dissipation of the photovoltaic panels. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Combine the following Figures 1 to 6 As shown, an embodiment of the present invention provides a splicing mechanism for fixing photovoltaic components and a photovoltaic curtain wall, including a plurality of photovoltaic panels 1, and also including a gap control splicing mechanism 2 for connecting the photovoltaic panels 1, and an automatic adjustment mechanism 3 for controlling the movement of the gap control splicing mechanism 2 according to temperature changes between the photovoltaic panels 1. The gap control splicing mechanism 2 includes a guide installation component 24 and a regulating component. The guide installation component 24 is composed of a necking portion 242 and an insertion portion 243 from top to bottom. A guide portion 241 is arranged on the outer side of the necking portion 242. Side connecting blocks 23 are arranged on the photovoltaic panels 1 at both ends of the photovoltaic curtain wall, and a slide groove is arranged in the side connecting block 23.

[0031] Specifically, the diameter of the necked portion 242 is larger than that of the inserting portion 243 , and the connecting portion between the necked portion 242 and the inserting portion 243 is arc-shaped. Meanwhile, the inner diameter of the necked portion 242 gradually decreases, and through grooves are provided at the inserting portion 243 and the necked portion 242 .

[0032] During operation, when the necking portion 242 is larger than the inner diameter of the inserting portion 243 , the inserting portion 243 can be easily inserted into the necking portion 242 , and the inner diameter of the necking portion 242 gradually decreases, which is convenient for limiting the position of the inserting portion 243 .

[0033] Specifically, the regulating component includes a connecting sliding block 25, the connecting sliding block 25 is located in the guide installation component 24, the two sides of the sliding connecting block 23 are rotatably connected with the control rod 21, the end of the control rod 21 is connected to the connecting block 23, the surface of the photovoltaic panel 1 is provided with a connecting frame 22, the connecting frame 22 is provided with a sliding groove, the sliding groove is divided into a first part and a second part, the connecting block 23 is provided with a movable block 28, the movable block 28 is located in the sliding groove, a part of the sliding groove is provided with a plurality of spring limit blocks 211, the side wall of the spring limit block 211 is provided with a groove, the groove is provided with a A movable limit rod 212 is provided to limit the position of the spring limit block 211, a movable limit block 29 is provided on the inner side of the movable block 28, the movable limit block 29 passes through the connecting frame 22, and a resisting telescopic rod 210 is provided on one side of the bottom end of the movable limit block 29, and the contact surface between the movable end 31 of the resisting telescopic rod 210 and the movable limit is an inclined surface, a hydraulic telescopic rod 27 is installed on the surface of the guide mounting assembly 24, and the hydraulic telescopic rod 27 is located between the two photovoltaic panels 1, the hydraulic telescopic rod 27 and the resisting telescopic rod 210 are connected by a connecting pipe 26, and a buffer block is provided under the connecting sliding block 25.

[0034] Specifically, the end surface of the movable block 28 is an arc surface, and in the initial state, the height of the movable limit block 29 is higher than the arc surface height of the movable block 28 .

[0035] During operation, although the end of the movable block 28 is an arc surface, the movable limit block 29 is still able to limit the movable block 28 due to the relatively high height of the movable limit block 29 in the initial state.

[0036] Specifically, one side surface of the spring limiting block 211 is a curved surface.

[0037] Specifically, the end of the control rod 21 is in an arc hook shape, and the end of the control rod 21 is made of a plastic material.

[0038] Specifically, the automatic adjustment mechanism 3 includes a fixed end 33, the fixed end 33 is located in the guide portion 241, a limiting block 32 is arranged inside the fixed end 33, a movable end 31 is arranged above the limiting block 32, and the limiting block 32 and the movable end 31 are connected by a spring.

[0039] During operation, a high expansion ratio gas or liquid is added to the gap between the limiting block 32 and the fixed end 33. When affected by the temperature, the internal medium will expand, thereby pushing the limiting block 32 upward in the opposite direction. It should be noted that the automatic adjustment mechanism 3 at this time needs to be adjusted and replaced according to the outer diameter of the photovoltaic panel 1 during actual use. When the diameter of the photovoltaic panel 1 is too large, the automatic adjustment mechanism 3 can be replaced with a temperature-controlled electric telescopic rod to ensure that the driving force can cause the upper photovoltaic panel 1 to move.

[0040] Working principle: When in use, first move the limit rod 212 so that the limit rod 212 moves out from the limit rod 212 in the elastic limit block, so that the spring limit can move, and then connect the connecting frame 22 to the photovoltaic panel 1. During the connection process, just pay attention to the installation height of the connecting frame 22, and then connect the side connecting block 23 to the outermost photovoltaic panel 1 (it is explained at this time that the height of the connecting frame 22 is a uniform height). When the installation is completed, the upper adjacent photovoltaic panel 1 is connected to the connecting frame 22, and then the control rod 21 movably connected to the connecting frame 22 is connected to the sliding block 25, and the friction coefficient between the buffer block under the connecting sliding block 25 and the inner wall of the guide installation assembly 24 is adjusted by bolts. When installing the connecting frame During the process of 22, no excessive requirements are made on the gap between the photovoltaic panels 1 (the gap can be lower than the active length when the insertion part is in the necking part 243). After the four photovoltaic panels 1 are installed, the insertion part 243 between the upper photovoltaic panels 1 is inserted into the necking part 242. At this time, the insertion part 243 can be guided to the position under the action of the guide part 241. Then, the pulling force on the upper photovoltaic panel 1 is relaxed. At this time, the upper photovoltaic panel 1 will automatically move downward under the action of gravity, and in the process of the insertion part 243 moving downward, it will contact the connecting sliding block 25, driving the connecting sliding block 25 to move downward synchronously. When the connecting sliding block 25 moves downward, at this time, due to the length of the control rod 21 connecting the connecting sliding block 25 and the connecting frame 22, The connecting block 23 is connected to the side plate 23 by the movable stop block 29, and the movable block 28 is connected to the side plate 23 by the movable stop block 29, so that the photovoltaic panel 1 at this location can be pulled and pulled through the control rod 21. 21 will also deflect, but the control rod 21 is not restricted in position, so it will not drive the photovoltaic panel 1 to move, so that when the displacement is performed, the photovoltaic panel 1 will only move in one direction. At the same time, in the process of the connecting sliding block 25 moving downward, it will first contact the buffer block to reduce the descending inertia, and then drive the buffer block to move downward. The downward movement of the buffer block will squeeze the movable end 31. Since the pressure in the limiting block 32 and the fixed end 33 is relatively large, the spring between the movable end 31 and the limiting block 32 will be squeezed first, so that the position of the movable end 31 changes. With the continuous displacement, the downward movement of the buffer block is actually affected by the downward movement of the connecting sliding block 25. Therefore, when the movable end 31 moves downward, the connecting sliding block 25 is actually moving downward at this time.The downward movement of the connecting sliding block 25 will continuously pull the connecting block 23 connected at the end to change its position through the control rod 21. Under the action of this movement trend, the gap between the two photovoltaic panels 1 is continuously reduced until the gap is small enough that the two photovoltaic panels 1 squeeze the hydraulic telescopic rod 27, so that the liquid in the hydraulic telescopic rod 27 enters the contact telescopic rod 210 through the connecting pipe 26, and the movable part of the contact telescopic rod 210 extends to contact the movable limit block 29, so that the movable limit block 29 moves downward, thereby releasing the limiting effect on the movable block 28, and the connecting sliding block 25 is displaced under the action of the control rod 21. When the control rod 21 is displaced, it will continuously squeeze the passing spring limit block 211. At this time, the downward movement of the connecting sliding block 25 no longer pulls the photovoltaic panel 1 to move, thereby achieving the effect of controlling the gap between the two photovoltaic panels 1. When a group of photovoltaic panels 1 is installed, the limit rod 212 is reset, so that the spring limit block 211 can no longer change its position. In the subsequent process, the position change of the control rod 21 will drive the photovoltaic panel 1 at that location to move, and then the control rod 21 located in the right slide groove of the connecting frame 22 will be connected to the connecting sliding block 25 in another splicing component, so as to complete the connection of multiple photovoltaic panels 1. The connection of multiple photovoltaic panels 1 is combined into a photovoltaic curtain wall (it should be noted that the connecting frame 22 in the photovoltaic panel 1 at the top is moved by human intervention). In the later use process, the gap between the photovoltaic panels 1 is small, which makes it difficult to remove the heat of the photovoltaic panel 1. At this time, the medium in the limiting block 32 and the fixed end 33 expands, which will push the movable end 31 to rise, thereby driving the movable limit block 29 to move upward. The upward movement of the movable limit block 29 will drive the photovoltaic panel 1 to move through the control rod 21, and at the same time, it will push the insertion part 243 located above the movable limit block 29, so that the gap between the photovoltaic panels 1 becomes larger, which promotes the heat dissipation effect.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
