Description

Technical Field

[0001] This utility model relates to the field of BIPV water channel technology, specifically to a building roof water channel for BIPV. Background Technology

[0002] BIPV drainage channels refer to drainage channels integrated with a system. BIPV systems typically integrate photovoltaic modules with the structure, facade, or roof of a building to generate clean solar power, while BIPV drainage channels are auxiliary facilities designed to effectively guide and discharge rainwater or snowmelt.

[0003] A water channel for waterproofing building roofs used in BIPV (publication number: CN222632664U) includes: a channel body, with the channel body installed at the gap between each pair of adjacent photovoltaic panels, and a protrusion extending upward from the center of the channel body; the protrusion divides the channel body into two water collection channels, each water collection channel having several diversion channels; a filter screen is fixed at the bottom of the diversion channels; a water collection chamber is fixed at the bottom of the channel body; the slope on both sides of the protrusion accelerates the drainage speed of the water flow, thereby improving drainage efficiency; due to the protrusion, a relatively high area is formed in the center of the channel body, making it easier for water to flow to both sides and avoiding water accumulation in the center; this helps reduce the potential damage of moisture to the building and photovoltaic panels, while keeping the channel body dry and clean; moreover, the protrusion changes the direction and speed of the water flow, making it easier for impurities and particles to settle in the water collection chamber, making cleaning work more convenient and efficient.

[0004] The aforementioned patents achieve more convenient and efficient cleaning through the cooperation of components such as the trough and the diversion trough. However, they cannot achieve the same level of cleaning and unblocking effect by using the water guide plate. Furthermore, the aforementioned patents cannot clean heavily adhered dirt. Therefore, we propose a water guide trough for building roofs in BIPV. Utility Model Content

[0005] This utility model proposes a building roof drainage channel for BIPV, which solves a problem in the related technology of building roof drainage channels for BIPV.

[0006] According to one aspect, at least one embodiment of the present invention provides a drainage channel for a building roof of a BIPV (Building Integrated Photovoltaic) system, comprising: a container, wherein a drainage channel plate is fixedly connected to the top of the container, and a dredging and cleaning device is provided on the top of the drainage channel plate;

[0007] The unclogging and cleaning device includes a slot on the top of a water guide plate. A rotating shaft is rotatably connected to the inner side of the slot, and a gear is fixedly connected to the circumference of the rotating shaft. A toothed rod is slidably connected to the inner side of the water guide plate, and a support rod is fixedly connected to one end of the toothed rod. An extension rod is fixedly connected to the side of the support rod, and a fixing rod is fixedly connected to the side of the extension rod. A push plate is fixedly connected to one end of the fixing rod. These components work together mechanically to achieve the functions of unclogging and cleaning. The movement of the push plate effectively removes accumulated debris from the water tank, achieving the desired unclogging and cleaning effect.

[0008] For example, in at least one embodiment of this utility model, a drainage channel for a building roof used in BIPV is provided, which further includes: the width of the drainage channel plate is one meter, and the height of the drainage channel plate is fifty centimeters. These dimensions ensure that the drainage channel plate has sufficient capacity and effective drainage function, can cope with changing weather conditions and water flow, avoid water blockage or water accumulation, thereby keeping the building or related areas dry and safe.

[0009] The gear meshes with the rack, and the diameter of the push plate matches the opening diameter of the water guide trough. The meshing of the gear and rack ensures efficient power transmission and precise movement of the push plate, while the design that the push plate diameter matches the opening diameter enhances the cleaning effect and working efficiency of the device.

[0010] The push plate and fixing rods are provided in multiple ways, and the multiple fixing rods are fixedly connected by connecting rods. This design of multiple fixing rods and connecting rods can enhance the stability of the structure, distribute the force evenly, improve the cleaning effect, and at the same time increase durability and ease of maintenance, ensuring the high efficiency and reliability of the entire system in long-term use.

[0011] The rotating shaft has multiple handles arranged in a circular array along its circumference. This arrangement of multiple handles along the circumference improves operational comfort, precision, and safety, while also enhancing the device's durability and providing more flexible operation.

[0012] The slot is located at the top of the water guide plate, and multiple water guide plates are provided. The design of slots at the top of the water guide plate and multiple water guide plates can effectively improve the guiding and distribution efficiency of water flow, prevent water accumulation, enhance the stability of the equipment, and improve the overall performance and durability of the drainage system.

[0013] The multiple water guide plates mesh with each other, and the bottom of the pusher plate contacts the top of the water guide plates. The design of meshing between the multiple water guide plates and contact between the pusher plate and the water guide plates can effectively improve the guidance, flow efficiency, stability and control of water flow, while reducing friction and the possibility of water backflow, thereby ensuring the smooth operation of the entire drainage system.

[0014] According to another aspect, at least one embodiment of this utility model also provides a solution for a building roof drainage channel in BIPV, comprising: a channel plate maintenance device provided on the side of the push plate, the channel plate maintenance device including a coating box, the side of the coating box being fixedly connected to the side of the push plate, an inlet provided on the top of the coating box, a rotating shaft rotatably connected to the top of the inlet, a cover plate fixedly connected to the circumferential surface of the rotating shaft, a slot opened on the side of the coating box, a rotating column rotatably connected to the inner side of the slot, and a coating roller fixedly connected to the circumferential surface of the rotating column. The channel plate maintenance device, through automatic coating and maintenance functions, can protect the drainage channel plate, evenly distribute the coating, extend the life of the drainage channel plate, reduce manual intervention, and improve overall operational efficiency. It achieves the effect of preventing the drainage channel plate from rusting.

[0015] For example, in at least one embodiment of this utility model, a water-guiding channel for a building roof used in BIPV further includes: the side of the water-guiding channel plate is located on the displacement trajectory of the coating roller, and two slots are provided, with the two slots being symmetrical about the longitudinal axis of the coating box. The function of the water-guiding channel plate and the slots is to ensure that the paint can flow evenly during the coating process, prevent paint waste or uneven distribution, thereby improving the quality of the coating effect.

[0016] Two rotating columns and coating rollers are provided, each corresponding to one of the two slots. A return torsion spring is fixedly connected to the circumferential surface of the rotating shaft, with one end of the return torsion spring fixedly connected to the top of the feed inlet. The synchronous operation of the two rotating columns and coating rollers improves the uniformity and coating quality of the coating.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. This utility model achieves its functionality through the coordinated operation of components such as a rotating shaft, gears, racks, extension rods, push plates, and handles. The operator rotates the handle, which in turn rotates the rotating shaft. This rotation drives the gears, which in turn drive the racks to move horizontally. The horizontal movement of the racks then drives the support rods, which in turn drives the extension rods, which in turn drives the fixed rods, which in turn drive the push plates. This horizontal movement of the push plates effectively unclogs and cleans the water channel. This achieves the functions of unclogging and cleaning; the movement of the push plates effectively removes accumulated debris from the water channel, resulting in a clear and unclogging effect.

[0019] 2. This utility model achieves automatic coating and maintenance functions through the coordinated operation of components such as a rotating shaft, gripping rod, push plate, coating box, rotating column, and coating roller. The operator rotates the gripping rod, which in turn rotates the rotating shaft. The rotating shaft then rotates the gear, which in turn drives a meshing rack to move horizontally. This horizontal movement of the rack drives a support rod, which in turn drives an extension rod, which in turn drives a fixing rod, which in turn drives a push plate, which in turn drives the coating box, which in turn drives the rotating column, which in turn drives the coating roller. This horizontal movement of the coating roller coats the sides of the water guide channel plate. This achieves automatic coating and maintenance, protecting the water guide channel plate, uniformly distributing the coating, extending the lifespan of the water guide channel plate, reducing manual intervention, and improving overall operational efficiency.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-6 As shown, it illustrates a building roof drainage channel for BIPV in one embodiment of the present invention, comprising: a container 1, a drainage channel plate 2 fixedly connected to the top of the container 1, and a dredging and cleaning device 3 provided on the top of the drainage channel plate 2;

[0033] The unblocking and cleaning device 3 includes a slot 31, which is formed on the top of the water guide plate 2. A rotating shaft 32 is rotatably connected to the inner side of the slot 31, and a gear 33 is fixedly connected to the circumferential surface of the rotating shaft 32. A toothed rod 34 is slidably connected to the inner side of the water guide plate 2. A support rod 35 is fixedly connected to one end of the toothed rod 34, and an extension rod 36 is fixedly connected to the side of the support rod 35. A fixing rod 37 is fixedly connected to the side of the extension rod 36, and a push plate 38 is fixedly connected to one end of the fixing rod 37. These components achieve the functions of unblocking and cleaning through mechanical linkage. The movement of the push plate 38 can effectively clean the accumulated debris in the water tank, achieving the effect of unblocking and cleaning.

[0034] In some examples, the drainage channel 2 is also included to have a width of one meter and a height of fifty centimeters. These dimensions ensure that the drainage channel 2 has sufficient capacity and effective drainage function to cope with varying weather conditions and water flow, preventing water blockage or water accumulation, thereby keeping the building or related area dry and safe.

[0035] Gear 33 meshes with rack 34, and the diameter of push plate 38 is the same as the diameter of slot 45 of water guide plate 2. The meshing of gear 33 and rack 34 ensures effective power transmission and precise movement of push plate 38, while the design that the diameter of push plate 38 is the same as the diameter of slot 45 enhances the cleaning effect and working efficiency of the device.

[0036] Multiple push plates 38 and fixing rods 37 are provided, and connecting rods 39 are fixedly connected to each other. This design of multiple fixing rods 37 and connecting rods 39 can enhance the stability of the structure, distribute the force evenly, improve the cleaning effect, and at the same time increase durability and ease of maintenance, ensuring the high efficiency and reliability of the entire system in long-term use.

[0037] A plurality of grips 310 are provided on the circumferential surface of the rotating shaft 32, and the plurality of grips 310 are arranged in an array along the circumference of the rotating shaft 32. The design of the plurality of grips 310 arranged in an array along the circumference of the rotating shaft 32 can improve the comfort, accuracy and safety of operation, while enhancing the durability of the equipment and providing a more flexible operating method.

[0038] The slot 31 is located at the top of the water guide plate 2, and multiple water guide plates 2 are provided. The design of the slot 31 at the top of the water guide plate 2 and multiple water guide plates 2 can effectively improve the guiding and distribution efficiency of water flow, prevent water accumulation, enhance the stability of the equipment, and improve the overall performance and durability of the drainage system.

[0039] Multiple guide plates 2 mesh with each other, and the bottom of the push plate 38 contacts the top of the guide plates 2. The design of meshing multiple guide plates 2 and contact between the push plate 38 and the guide plates 2 can effectively improve the guidance, flow efficiency, stability and control of water flow, while reducing friction and the possibility of water backflow, thereby ensuring the smooth operation of the entire drainage system.

[0040] The operator rotates the lever 310, which drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the gear 33 to rotate, which in turn drives the meshing rack 34 to move horizontally. The horizontal movement of the rack 34 drives the support rod 35 to move horizontally, which in turn drives the extension rod 36 to move horizontally. The horizontal movement of the extension rod 36 drives the fixed rod 37 to move horizontally, which in turn drives the push plate 38 to move horizontally. The horizontal movement of the fixed rod 37 drives the connecting rod 39 to move horizontally, which in turn drives multiple fixed rods 37 to move horizontally. The horizontal movement of the push plate 38 thus unclogs and cleans the dirt in the water guide plate 2.

[0041] like Figures 1-6 As shown, this illustration depicts a BIPV (Building Integrated Photovoltaic) roof drainage channel, which is largely the same as the technical solution in Embodiment 1. Therefore, only the differences are described, including: a channel plate maintenance device 4 is provided on the side of the push plate 38. The channel plate maintenance device 4 includes a coating box 41, the side of which is fixedly connected to the side of the push plate 38. An inlet 42 is provided at the top of the coating box 41, and a rotating shaft 43 is rotatably connected to the top of the inlet 42. A cover plate 44 is fixedly connected to the circumferential surface of the rotating shaft 43. A slot 45 is opened on the side of the coating box 41, and a rotating column 46 is rotatably connected to the inner side of the slot 45. A brushing roller 47 is fixedly connected to the circumferential surface of the rotating column 46. The channel plate maintenance device 4, through automatic coating and maintenance functions, can protect the drainage channel plate 2, evenly distribute the coating, extend the life of the drainage channel plate 2, reduce manual intervention, and improve overall operational efficiency. This achieves the effect of preventing the drainage channel plate 2 from rusting.

[0042] In some examples, the water guide plate 2 is located on the displacement trajectory of the coating roller 47, and two slots 45 are provided, which are symmetrical about the longitudinal axis of the coating box 41. The function of the water guide plate 2 and the slots 45 is to ensure that the paint can flow evenly during the coating process, prevent paint waste or uneven distribution, and thus improve the quality of the coating effect.

[0043] Two rotating columns 46 and coating rollers 47 are provided, corresponding to two slots 45. A return torsion spring 48 is fixedly connected to the circumferential surface of the rotating shaft 43, and one end of the return torsion spring 48 is fixedly connected to the top of the feed inlet 42. The two rotating columns 46 and coating rollers 47 improve the uniformity and coating quality of the coating by working synchronously.

[0044] For example, as shown in Figures 1-6, the operator rotates the lever 310, which drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the gear 33 to rotate, which in turn drives the meshing rack 34 to move horizontally. The horizontal movement of the rack 34 drives the support rod 35 to move horizontally, which in turn drives the extension rod 36 to move horizontally. The horizontal movement of the extension rod 36 drives the fixing rod 37 to move horizontally, which in turn drives the push plate 38 to move horizontally. The horizontal movement of the push plate 38 drives the coating box 41 to move horizontally, which in turn drives the rotating column 46 to move horizontally. The horizontal movement of the rotating column 46 drives the coating roller 47 to move horizontally, thus coating the side of the water guide plate 2.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
