Description

Technical Field

[0001] The utility model relates to the technical field of building integrated photovoltaic, and is a vertical water guiding photovoltaic tile connector and a photovoltaic tile system. Background Art

[0002] BIPV (Building Integrated Photovoltaic) is a photovoltaic power generation system that is designed, constructed, and installed simultaneously with a new building and integrated with the building. It is an essential part of the building, playing both the functions of building materials (such as wind protection, rain protection, heat insulation, etc.) and power generation, making the building a green building. The application demand for photovoltaic tiles on tile roofs is increasing. Photovoltaic tiles usually have photovoltaic modules attached with aluminum alloy frames and are installed by hanging on-site, which is becoming a trend.

[0003] Existing products are divided into two installation methods: horizontal hanging installation and vertical clamping installation. Vertical installation means that the long axis of the photovoltaic tile is perpendicular to the ground, while horizontal installation means that the long axis of the photovoltaic tile is parallel to the ground. Due to the good decorative effect of vertical clamping installation, it is favored by the majority of users. Chinese patent document CN114809480A (202210633926.9) provides a photovoltaic shed roof structure and a photovoltaic parking shed. This patent uses a keel assembly and a crossbeam assembly to assemble multiple photovoltaic panels into a multi-row and multi-column arrangement. During use, a drainage slope is formed by the crossbeam assembly to achieve the effect of overall large-area drainage. The water seeping down from the crossbeam assembly is collected through an internal water collection tank and discharged from the end to the internal drainage channel on the keel assembly, thus realizing the vertical installation of the photovoltaic tile. However, the internal water collection tank in this patent is parallel to the ground, which is prone to water accumulation and increases the drainage pressure of the internal drainage channel on the keel assembly.

[0004] Chinese patent document CN208572012U (201821411963.0) discloses a connection mechanism between solar laminates, a solar photovoltaic module, and a solar roof surface. According to the characteristics of the high and low inclination of the component installation, the above patent uses the flying frame on the first frame to extend and overlap on the second frame of the lower photovoltaic module to achieve the waterproof function. However, the above patent needs to make the flying frame on the first frame reach a certain length to avoid backflow caused by wind, resulting in an increase in material cost and roof load. Summary of the Utility Model

[0005] The main object of the present utility model is to provide a vertical water-conducting photovoltaic tile connector and a photovoltaic tile system. The present utility model sets a first frame and a second frame at the edge of the connector to be connected, and seals and connects the sealing cover plate on the first frame with the glue-containing groove on the second frame, thereby solving the problem of water leakage at the joint where two connectors to be connected are parallel to the ground and improving the sealing effect.

[0006] The technical problem to be solved by the present utility model is realized by the following technical solutions: A vertical water-conducting photovoltaic tile connector, comprising a connector to be connected, a first frame and a second frame;

[0007] Both the first frame and the second frame include a horizontally arranged frame groove, and the edge of the connector to be connected is hermetically arranged in the frame groove;

[0008] The first frame is provided with a sealing cover plate on the right side of the frame groove;

[0009] The second frame is provided with a glue-containing groove with an upward opening on the left side of the frame groove;

[0010] The sealing cover plate overlaps above the glue-containing groove, and the sealing cover plate is hermetically connected with the glue-containing groove.

[0011] Preferably, a sealing glue is provided between the sealing cover plate and the glue-containing groove. By injecting the sealing glue into the glue-containing groove and using the sealing glue to hermetically connect the sealing cover plate with the glue-containing groove, the infiltration of rainwater can be effectively prevented.

[0012] Preferably, a first sealing edge is provided below the sealing cover plate;

[0013] The first sealing edge is located in the glue-containing groove, and the first sealing edge is in contact with or has a clearance fit with the side wall surface of the glue-containing groove. By providing a first sealing edge below the sealing cover plate and allowing the sealing glue to enter between the first sealing edge and the side wall of the glue-containing groove, a better sealing effect can be achieved.

[0014] Preferably, a second sealing edge is further provided below the sealing cover plate;

[0015] The second sealing edge is located on the left side of the first sealing edge;

[0016] The second sealing edge is arranged at an interval from the first sealing edge, and the second sealing edge is located in the glue-containing groove. The second sealing edge contacts and solidifies with the sealing glue in the glue-containing groove, and on the basis of the first sealing edge, it plays a dual-sealing role to avoid rainwater infiltration caused by insufficient thickness of the sealing glue at the first sealing edge.

[0017] Preferably, the second frame is provided with a glue overflow groove with an upward opening on the left side of the frame groove;

[0018] The glue overflow groove is located on the left side of the glue storage groove. By providing the glue overflow groove, it is used to control the amount of sealant added to the glue storage groove, ensuring that the sealing requirements are met. When there is sufficient sealant in the glue storage groove, it can prevent the sealant from overflowing outside the second frame to contaminate the surface of the photovoltaic module.

[0019] Preferably, the cross-section of the frame groove is a U-shaped structure;

[0020] The edge of the component to be connected is inserted into the frame groove, and a sealant or gasket is provided between the component to be connected and the frame groove. By setting the cross-section of the frame groove as a U-shaped structure, it is convenient for the installation and sealing of the component to be connected.

[0021] Preferably, the cross-section of the frame groove is a right-angled plate shape;

[0022] The edge of the component to be connected overlaps in the frame groove, and a sealant is provided between the component to be connected and the frame groove. By setting the cross-section of the frame groove as a right-angled plate shape, the edge of the component to be connected can be directly overlapped in the frame groove, which is more convenient for assembly.

[0023] The present utility model also discloses a vertically water-conducting photovoltaic tile system, which adopts the above-mentioned vertically water-conducting photovoltaic tile connector, and includes drainage structures arranged at intervals, and the component to be connected is fixedly arranged on the drainage structure;

[0024] The drainage structure includes a drainage groove with an upward opening, and the components to be connected are arranged at intervals along the width direction of the drainage groove;

[0025] The drainage grooves are respectively arranged at both ends of the first frame and the second frame, and the drainage grooves are located below the glue storage groove.

[0026] Preferably, the present utility model further includes a water guide member arranged at the end of the second frame;

[0027] The water guide member includes a water guide edge located below the glue storage groove, and the water guide edge is used to introduce the rainwater flowing down from both ends of the first frame and the second frame into the drainage groove, preventing the rainwater from dripping onto the interior of the building along the lower surface of the component to be connected;

[0028] Preferably, the water guide member is detachably arranged on the second frame. A clamping groove is arranged at the lower end of the second frame, and a plug-in edge is arranged above the water guide edge of the water guide member, and the plug-in edge is inserted into the clamping groove. By inserting the plug-in edge of the water guide member into the clamping groove at the lower end of the second frame, it is convenient for assembly.

[0029] Preferably, the component to be connected includes a plate or a photovoltaic module. The vertically water-conducting photovoltaic tile connector can meet the connection of the plate in conventional building materials while realizing the connection of the photovoltaic module.

[0030] Compared with the prior art, the beneficial effects of the present utility model are as follows: The edge of the component to be connected is hermetically arranged in the frame grooves of the first frame and the second frame, avoiding water leakage from the joint between the component to be connected and the first frame or the second frame.

[0031] Since the first frame is provided with a sealing cover plate on the right side of the frame groove, and the second frame is provided with a glue receiving groove with an upward opening on the left side of the frame groove. By overlapping the sealing cover plate above the glue receiving groove and hermetically connecting the sealing cover plate and the glue receiving groove, rainwater can flow away along the joint of the two components to be connected, without water leakage and water accumulation at the joint of the two components to be connected, improving the drainage effect.

[0032] In the vertical water-conducting photovoltaic tile system of the present utility model, the component to be connected is fixedly arranged on the drainage structures arranged at intervals. Since the drainage structures are provided with drainage grooves with upward openings, the drainage grooves are respectively arranged at both ends of the first frame and the second frame. Since the drainage grooves are located below the glue receiving grooves, the rainwater flowing down from above the vertical water-conducting photovoltaic tile connectors will gather in the drainage grooves and be effectively drained away, reducing the impact of rainwater on the components to be connected.
