As an important component, the drainage trough must be designed and used to ensure that water can be effectively discharged without affecting the power generation efficiency or structural safety of the photovoltaic panels.
[0003] Currently, drainage channels are generally U-shaped structures. During use, they are installed at the bottom between two sets of photovoltaic power generation devices to collect and drain rainwater. However, in actual use, when the rainfall is heavy or the water flow is large, the U-shaped drainage channel will be impacted by the rainwater, causing deformation on both sides, which will affect the function of the drainage system. Therefore, there is an urgent need for a drainage channel for photovoltaic power generation device drainage system to solve the above problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0007] A drainage trough for a photovoltaic power generation device drainage system includes a drainage trough, with reinforcing members and sealing members installed on both sides of the drainage trough. The reinforcing members are located at the bottom of the sealing members. A drainage component is installed inside the drainage trough. The reinforcing members include a connecting plate installed at the bottom of the drainage trough.

[0011] As an improved technical solution, the drainage component includes a guide plate fixed inside the drainage channel. The guide plate is inclined, and a pulley is movably connected inside the guide plate. There are two sets of pulleys, which are arranged at equal intervals and correspond to each other.
[0012] As an improved technical solution, the guide plate has an internal mounting groove adapted to the pulley, and multiple sets of pulleys correspond one-to-one with the mounting groove.

[0031] like Figures 1 to 5 As shown in the figure, this embodiment provides a drainage trough for a photovoltaic power generation device drainage system. The drainage trough of this photovoltaic power generation device drainage system includes a drainage trough 1. Reinforcing members 2 and sealing members 4 are installed on both sides of the drainage trough 1. The reinforcing members 2 are located at the bottom of the sealing members 4. A drainage member 3 is installed inside the drainage trough 1.
[0032] The reinforcement component 2 includes a connecting plate 21 installed at the bottom of the drainage trough 1. A triangular reinforcing rib 22 is fixedly connected to one end of the connecting plate 21 away from the drainage trough 1. A base plate 23 is fixedly connected to the bottom of the triangular reinforcing rib 22. One side of the base plate 23 is fixedly connected to the connecting plate 21. The connecting plate 21, the triangular reinforcing rib 22, and the base plate 23 are all arranged at equal intervals. The triangular reinforcing rib 22 can disperse external forces and increase the rigidity of the drainage trough 1, making it less prone to bending or deformation under the impact of water flow or external pressure. At the same time, it can provide stronger support for the drainage trough 1 and enhance the overall stability of the drainage trough 1. In this way, when the drainage trough 1 is subjected to large water flow or heavy rain, it can help to balance the force and avoid local overload leading to damage.
[0033] Multiple sets of triangular reinforcing ribs 22 are connected by connecting rods 24. There are two sets of connecting rods 24, which correspond to each other. Anti-detachment blocks 25 are fixedly installed at both ends of the two sets of connecting rods 24. The connecting rods 24 can connect multiple sets of triangular reinforcing ribs 22, which facilitates their installation and transportation. The anti-detachment blocks 25 can prevent the triangular reinforcing ribs 22 from separating from the connecting rods 24. The setting of two sets of connecting rods 24 can prevent the triangular reinforcing ribs 22 from shifting.
[0034] The connecting plate 21 is equipped with plugs 26. Two sets of plugs 26 are located on both sides of the triangular reinforcing rib 22. The connecting plate 21 is connected to the drainage channel 1 through the plugs 26. The plugs 26 are bolt structures, which can facilitate the installation of the reinforcing parts 2 on both sides of the drainage channel 1.
[0035] The triangular reinforcing rib 22 has a through hole 27 inside. The through hole 27 is located between the two sets of connecting rods 24. The through hole 27 can reduce the overall weight of the triangular reinforcing rib 22 and optimize the material use of the triangular reinforcing rib 22 without reducing the strength.
[0036] The drainage component 3 includes a guide plate 31 fixed inside the drainage trough 1. The guide plate 31 is inclined, and a pulley 32 is movably connected inside the guide plate 31. There are two sets of pulleys 32, which are arranged at equal intervals and correspond to each other. The pulleys 32 provide a smooth track on both sides of the guide plate 31, reducing the friction between impurities and the wall of the drainage trough 1, thereby reducing the chance of impurities getting stuck or remaining. The presence of the pulleys 32 helps to reduce the adhesion of impurities, making them easier to slide in the trough. The inclined shape of the guide plate 31 facilitates the flow of water, thereby reducing the possibility of water remaining inside the drainage trough 1.
[0037] The inside of the guide plate 31 is provided with a mounting groove 33 that is adapted to the pulley 32. Multiple sets of pulleys 32 correspond one-to-one with the mounting groove 33, and the pulleys 32 are located inside the mounting groove 33.
[0038] The guide plate 31 has a water channel 34 inside. The water channel 34 is located at the bottom of the mounting groove 33 and the two are connected. This prevents water from entering the guide plate 31 after entering between the pulley 32 and the mounting groove 33. The water channel 34 can drain the water, thereby extending the service life of the guide plate 31.
[0039] The surface of the guide plate 31 is provided with guide grooves 35, which are arranged at equal intervals. Multiple sets of guide grooves 35 are located between two sets of pulleys 32. The guide grooves 35 are located at the top of the water channel 34 to facilitate the diversion of water source.
[0040] The sealing element 4 includes a mounting plate 41 fixed to the top of the drainage trough 1. There are two sets of mounting plates 41, which correspond to each other. A sealing strip 42 is installed inside the two sets of mounting plates 41. A rubber plate 43 is fixedly installed on the top of the sealing strip 42. The rubber plate 43 is trapezoidal, which can make the sealing strip 42 come into contact with the bottom of the photovoltaic equipment more tightly, thereby effectively preventing rainwater or other liquids from seeping into the drainage trough 1. It can also provide a buffer between the sealing strip 42 and the photovoltaic power generation equipment, reduce damage caused by vibration or external force, help extend the service life of the equipment, and ensure the stability of the device in long-term use. At the same time, it can also make the drainage trough 1 and the photovoltaic power generation device more tightly connected, thereby improving the stability of the entire structure and avoiding loosening or misalignment caused by external force or environmental changes.
[0041] In use, the connecting plate 21 is installed on both sides of the drainage trough 1 by means of the bolt 26 to increase the rigidity of the drainage trough 1. Then, the drainage trough 1 is installed at the bottom between the two sets of photovoltaic power generation devices, and the rubber plate 43 is tightly attached to the two sets of photovoltaic power generation devices. Then, the drainage trough 1 is fixed to the bottom of the two sets of photovoltaic power generation devices by means of fixing structures such as steel wire.
[0042] When the rain is heavy, the rainwater flows through the gap between the two sets of photovoltaic power generation devices into the drainage trough 1 and is discharged through the guide plate 31. At the same time, when large debris such as fallen leaves fall onto the guide plate 31, the rainwater washes the pulley 32, causing it to rotate. This allows the fallen leaves to move slowly as the pulley 32 rotates. Meanwhile, the pulley 32 can reduce the friction between the fallen leaves and the drainage trough 1, thus facilitating the discharge of large debris such as fallen leaves.
[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
