[0036] For building integrated photovoltaics, simply speaking, it is a technology of integrating photovoltaic components on a building, which can replace part of the traditional building structure as a functional part of the building structure. Considering the characteristics of photovoltaic components, a drainage structure needs to be set up to ensure the safety of the building integrated photovoltaics. However, the existing drainage structure of the building integrated photovoltaics is single, and cannot meet the use requirements of photovoltaic components in different scenes.

[0037] Therefore, the embodiments of the present application provide a drainage structure, which can meet the use requirements of photovoltaic components in different scenes, and the support moves towards or away from the bottom of the drainage groove, so that the depth of the flow guide space of the drainage structure is adjustable, thereby adapting to different drainage requirements and environmental conditions.

[0038] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the drawings.

[0039] As Figure 1 ,Figure 2 and Figure 3 The drainage structure provided by the embodiment of the utility model shows,

[0040] The support seat 10 is provided with installation positions for installing photovoltaic modules on both sides, and is provided with a concave drainage groove.

[0041] The support piece 20 is movably arranged in the drainage groove, and a flow guide space is formed between the support piece 20 and the inner side wall of the drainage groove. The support piece 20 moves along the height direction of the drainage groove, so that the depth of the flow guide space is adjustable.

[0042] In the technical scheme adopted in this embodiment, the support seat 10 is arranged to facilitate the installation of the photovoltaic module on the roof of the building main body. The concave drainage groove arranged on the support seat 10 is used to collect and guide water flow. The support piece 20 is arranged in the drainage groove and forms a flow guide space with the inner side wall of the drainage groove, which is used to temporarily store or guide water flow. Moreover, the support piece 20 is movably connected with the drainage groove, so that the height position of the support piece 20 can be adjusted according to different drainage requirements and environmental conditions. It can be understood that the closer the support piece 20 is to the bottom of the drainage groove, the deeper the flow guide space is. The farther the support piece 20 is from the bottom of the drainage groove, the shallower the flow guide space is. When it is necessary to reduce the risk of water accumulation and overflow, the depth of the flow guide space is increased to effectively collect and guide rainwater. When it is necessary to clean the drainage structure, the depth of the flow guide space is reduced to facilitate the cleaning of the sundries in the flow guide space. The technical scheme provided by the embodiment of the utility model changes the position of the support piece 20 to adjust the depth of the flow guide space, thereby improving the flexibility of the flow guide space and effectively meeting the use requirements of the photovoltaic module in different scenarios.

[0043] Specifically, the drainage structure includes the support seat 10 and the support piece 20.

[0044] The support seat 10 can be made of metal materials such as stainless steel and iron, has a certain bearing capacity, is usually fixed on the roof of the building main body, and can provide support for the photovoltaic module. The concave drainage groove arranged on the support seat 10 can be used to collect and guide water flow, so that rainwater can be discharged in an orderly manner, thereby reducing the risk of water accumulation or erosion of the photovoltaic module caused by scattered water flow. It can be understood that the deeper the drainage groove is, the smaller the risk of water accumulation and overflow is. Moreover, the concave drainage groove can more easily guide water and sundries to the drainage opening, thereby reducing the maintenance workload. The shape of the drainage groove can be designed according to the actual use, so as to meet the requirements of buildings and engineering and ensure that rainwater can be effectively discharged.

[0045] The support 20 is movably arranged on the support base 10 and can form a guide space with the side wall of the drain groove. It can be understood that the depth of the guide space can be changed by the movement of the support 20, so as to change the guide capacity of the drainage structure. Thus, the drainage efficiency can be adjusted in real time to adapt to different drainage requirements when the rainfall or other conditions change. The support 20 can be a telescopic plate and is movably connected with the support base 10. When it is necessary to increase the depth of the guide space, the support 20 is moved towards the bottom of the drain groove until abuts against the bottom of the drain groove. At this time, the guide space is the largest, so as to accelerate the water flow speed and reduce the risk of water accumulation. When it is necessary to reduce the depth of the guide space, the support 20 is moved towards the opening of the drain groove until the height of the opening of the drain groove is consistent. At this time, the guide space is the smallest, so as to facilitate the cleaning of the sundries retained in the guide space. Of course, in order to improve the stability of the support 20, a limiting piece can also be arranged on the side wall of the drain groove, so that the guide space is more stable and the displacement of the support 20 caused by water flow impact is reduced.

[0046] Further, with reference to Figure 2 、 Figure 3 and Figure 4 , in an embodiment of the present application, the support 20 comprises:

[0047] a first support plate 21, which is internally provided with a placing cavity and both sides of which are provided with openings in communication with the placing cavity;

[0048] a second support plate 22, which is movably arranged in the placing cavity and is provided with two second support plates 22 spaced apart along the width direction of the placing cavity, and each second support plate 22 corresponds to an opening; and

[0049] a resilient member 23, which is arranged in the placing cavity and is provided with at least two resilient members 23 spaced apart along the length direction of the placing cavity, and each second support plate 22 is connected with at least one resilient member 23;

[0050] wherein one end of each second support plate 22 can pass through an opening and abut against the inner side wall of the drain groove, so as to form a guide space between the support 20 and the inner side wall of the drain groove.

[0051] In the technical scheme adopted in this embodiment, the support 20 further comprises a first support plate 21, a second support plate 22 and an elastic member 23. In this embodiment, the first support plate 21 serves as a main body structure and is internally provided with a placing cavity for accommodating the second support plate 22 and the elastic member 23. Moreover, the first support plate 21 is provided with openings on both sides and in communication with the placing cavity, so that the second support plate 22 can extend out of the openings and abut against the inner side wall of the drain groove. The elastic member 23 is arranged in the placing cavity, and the second support plate 22 is pressed against the elastic member 23 in the placing cavity, so that the elastic member 23 is elastically deformed and has elastic force, thereby exerting a reaction force on the second support plate 22, so that the second support plate 22 can stably abut against the inner side wall of the drain groove. The elastic member 23 can be a spring, and an external force is exerted on the first support plate 21, so that the first support plate 21 moves towards the opening direction of the drain groove. At this time, the second support plate 22 can extend out of the placing cavity and abut against the side wall of the drain groove under the action of the spring elastic force. An external force in the opposite direction is exerted on the first support plate 21, so that the first support plate 21 moves towards the bottom direction of the drain groove. At this time, the second support plate 22 is accommodated into the placing cavity under the pressing action of the side wall of the drain groove. It can be understood that the second support plate 22 always abuts against the inner side wall of the drain groove, so as to ensure that a stable flow guiding space is formed between the support 20 and the inner side wall of the drain groove.

[0052] Further, with reference to Figure 3 In an embodiment of the utility model, the inner side wall of the placing cavity is provided with a fixed block 24, one end of the elastic member 23 is connected with the fixed block 24, and the other end is connected with the second support plate 22. The elastic member 23 has a tendency to move the second support plate 22 towards the inner side wall of the drain groove.

[0053] In the technical scheme adopted in this embodiment, the fixed block 24 can provide a fixed point for the elastic member 23, so that the elastic member 23 can store and release energy and provide continuous elastic force for the second support plate 22. Preferably, the fixed block 24 is arranged on the central axis of the placing cavity, so that the elastic force provided by the elastic members 23 on both sides is the same, thereby making the contact between the two second support plates 22 and the inner side wall of the drain groove more stable.

[0054] Further, with reference to Figure 2 、 Figure 3 In an embodiment of the utility model, the side of the second support plate 22 towards the inner side wall of the drain groove is provided with a slope with the same angle as the inner side wall of the drain groove, so that the second support plate 22 abuts against the inner side wall of the drain groove.

[0055] In the technical scheme adopted in the embodiment, the second support plate 22 can be more naturally attached to the inner side wall of the drain groove by being thus arranged. Moreover, as the angles of the inclined surfaces are the same, the second support plate 22 can be in close contact with the inner side wall of the drain groove without the need for additional adjustment or clearance. Meanwhile, the contact between the second support plate 22 and the inner side wall of the drain groove is more close, reducing the possibility of accumulation of sundries on the contact surface. In addition, the inclined arrangement of the inner side wall of the drain groove makes the movement of the second support plate 22 in the placement cavity more smooth.

[0056] Further, with reference to Figure 2 、 Figure 3 In an embodiment of the utility model, the sum of the width of the placement cavity and the width of the first support plate 21 extended by the two second support plates 22 is equal to the width of the opening of the drain groove.

[0057] In the technical scheme adopted in the embodiment, the support 20 and the drain groove can be seamlessly connected by being thus arranged, the sealing performance of the drain structure can be improved, the possibility of moisture penetrating into the structure can be reduced, and the stability of the entire drain structure is enhanced.

[0058] Further, with reference to Figure 3 、 Figure 4 In an embodiment of the utility model, the drain structure further comprises a sliding rail 25 fixedly connected to the inner side of the placement cavity of the first support plate 21, and the two second support plates 22 are both in sliding connection with the sliding rail 25.

[0059] In the technical scheme adopted in the embodiment, the sliding rail 25 can improve the smoothness of the sliding of the second support plate 22. The sliding rail 25 is in sliding connection with the second support plate 22, so that the position of the second support plate 22 can be flexibly adjusted to adapt to the size between the inner side walls of the drain groove at different heights.

[0060] Further, in an embodiment of the utility model, the drain structure further comprises a driving mechanism in driving connection with the support 20 to drive the support 20 to move along the height direction of the drain groove.

[0061] In the technical scheme adopted in this embodiment, the movement of the support 20 can be achieved by manual direct operation, thus the drainage structure can be simplified, but it needs to consume manpower to achieve, and there is limitation in operation, and the drainage efficiency is affected, in this embodiment, the drainage structure further comprises a driving mechanism, the driving mechanism is arranged on the support base 10, and the driving mechanism is in driving connection with the support 20, so as to drive the support 20 to move along the height direction of the drainage groove. It can be understood that the driving mechanism can drive the support 20 to move linearly relative to the support base 10 when working, so that the size of the flow guide space formed between the support 20 and the inner side wall of the drainage groove of the support base 10 changes. Through the arrangement of the driving mechanism, manual operation can be replaced, and the convenience of the drainage structure is improved

[0062] Further, in an embodiment of the utility model, the driving mechanism is a cylinder or a telescopic rod or a folding frame.

[0063] In the technical scheme adopted in this embodiment, different driving mechanisms can be selected according to the required movement range, force, speed and space limitation of the drainage structure, the driving mechanism can use a cylinder, can also use a telescopic rod, and can also use a folding frame, which is not limited here.

[0064] Further, referring to Figure 4 In an embodiment of the utility model, the drainage structure further comprises sealing pads 30, at least two sealing pads 30 are arranged along the width direction of the placement cavity of the first support plate 21, and at least one sealing pad 30 is arranged corresponding to each opening.

[0065] In the technical scheme adopted in this embodiment, the sealing pads 30 arranged can improve the sealing performance of the drainage structure, reduce the penetration of water from the gap between the first support plate 21 and the second support plate 22 into the placement cavity, and ensure that the water flow is effectively guided. It can be understood that the sealing pads 30 can accurately correspond to each opening, when the second support plate 22 passes through the opening and abuts against the inner side wall of the drainage groove, the sealing pads 30 are compressed to form a sealed state, preventing water from leaking around the second support plate 22, and enhancing the integrity of the drainage structure, so that the cooperation between the components is more closely.
