Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic power generation box-type substations, and particularly relates to a photovoltaic power generation box-type substation. Background Technology

[0002] Photovoltaic power generation box-type substations, also known as photovoltaic step-up box-type transformers, or simply photovoltaic box-type substations, are a specific application of box-type substations in new energy photovoltaic power generation.

[0003] For example, Chinese patent CN219459007U discloses a photovoltaic power generation box-type substation, including a substation, photovoltaic panels fixedly installed on the top of the substation, a fixed frame fixedly connected to the top of the substation, a drive rod rotatably connected to the outside of the fixed frame, a fixed bracket threadedly connected to the outside of the drive rod, an installation block snapped onto the outside of the fixed bracket, and a cleaning wipe fixedly connected to the outside of the installation block. The advantages of this utility model are: by setting the installation block and limiting post, it is convenient to quickly wipe the photovoltaic panels on the substation; the structure is simple and easy to use; it ensures the cleanliness of the photovoltaic panels while facilitating the replacement of the cleaning wipe, making it convenient to use and reducing production costs; by setting the fixed block and the lead pipe, it is convenient to concentrate and discharge rainwater from the top of the substation and the photovoltaic panels, avoiding water accumulation around the substation and effectively preventing water seepage into the substation, thus providing a certain degree of protection for the substation.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as the need for two motors to operate when wiping the photovoltaic panels, which increases power consumption and manufacturing costs. Furthermore, the motors are exposed to the elements, making them susceptible to damage from wind, sun, and rain. Therefore, we propose a photovoltaic power generation box-type substation. Utility Model Content

[0006] The purpose of this utility model is to provide a photovoltaic power generation box-type substation to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a photovoltaic power generation box-type substation, including a substation, two photovoltaic panels and two cleaning wipers, and further including:

[0008] A triangular top plate is fixedly installed on the top of the substation. A U-shaped rod is fixedly installed on the top of the triangular top plate. Two photovoltaic panels are fixedly installed on the top of the triangular top plate. A threaded rod is rotatably installed inside the U-shaped rod. A slider is slidably installed inside the U-shaped rod and on the threaded rod. Movable plates are fixedly installed on both sides of the slider. Two cleaning wipes are respectively inserted into the bottom of the two movable plates.

[0009] Two sets of fixing components are located within two movable plates and are used to fix two cleaning wipes respectively;

[0010] The power chamber is located inside the spiral rod. A first bevel gear and a second bevel gear are rotatably mounted inside the power chamber. One end of the second bevel gear passes through one side of the power chamber and is coaxially connected to the threaded rod. A groove is provided inside the triangular top plate. A motor is fixedly mounted inside the groove. One end of the motor passes through the top of the groove and is coaxially connected to the first bevel gear.

[0011] In this technical solution, when cleaning the two photovoltaic panels is required, the operator can start the motor. The motor's output shaft will drive the first bevel gear to rotate. Under the meshing action, the first bevel gear will drive the second bevel gear to rotate. Subsequently, the second bevel gear will drive the threaded rod to rotate. Under the action of the thread, the threaded rod will drive the slider to move. The slider will drive the two moving plates to move. Subsequently, the two moving plates will drive the two cleaning wipes to move. During the movement, the cleaning wipes will clean the surface of the photovoltaic panels. Under the action of the dustproof net, the heat generated by the motor will be dissipated to the outside through the dustproof net. In addition, the dustproof net can block dust and prevent dust from contacting the motor. The motor is installed in the groove, which also prevents the motor from being exposed to wind and sun.

[0012] In the above technical solution, the fixing component further includes:

[0013] A chute is formed inside a movable plate. A limiting block is slidably installed inside the chute. One end of the limiting block passes through the bottom of the chute and extends into the cleaning wipe. A pull rod is fixedly installed on the top of the limiting block. One end of the pull rod passes through the top of the chute and extends to the outside. A spring is sleeved on the pull rod and inside the chute.

[0014] In this technical solution, when disassembling the cleaning wipe, the worker can pull the lever by hand. The lever will cause the limit block to move upward, and the spring will be compressed and contracted until one end of the limit block is completely pulled out of the cleaning wipe, thereby releasing the fixation of the cleaning wipe. Then the cleaning wipe can be pulled out from the bottom of the moving plate.

[0015] In the above technical solution, one end of the limiting block is inserted into the cleaning wipe, both ends of the spring are tightly welded to the inner wall of the slide groove and the top of the limiting block, and the pull rod is slidably connected to the slide groove and the moving plate.

[0016] In this technical solution, it is ensured that one end of the limiting block can be inserted into the cleaning wipe, the spring structure is stable, and the pull rod can slide in the slide groove and the moving plate.

[0017] In the above technical solution, a dustproof net is further fixedly installed in the groove and below the motor.

[0018] In this technical solution, the heat generated by the motor will be dissipated to the outside through the dustproof net, and the dustproof net can block dust and prevent dust from contacting the motor. The motor is installed in the groove, which can also prevent the motor from being exposed to wind and sun.

[0019] In the above technical solution, the output shaft of the motor is rotatably connected to the triangular top plate and the boom rod, and the first bevel gear meshes with the second bevel gear.

[0020] In this technical solution, to ensure the normal operation of the motor, the motor is started, and the output shaft of the motor will drive the first bevel gear to rotate. Under the action of meshing, the first bevel gear will drive the second bevel gear to rotate.

[0021] In the above technical solution, a U-shaped guide pipe is fixedly installed at the bottom of the triangular top plate, and a drain pipe is fixedly installed at the bottom of the U-shaped guide pipe.

[0022] In this technical solution, it is ensured that the water flowing down from the triangular top plate can enter the U-shaped inlet pipe, and then enter the drain pipe for centralized drainage.

[0023] In the above technical solution, the slider is further connected to the threaded rod by a thread.

[0024] In this technical solution, the rotation of the threaded rod ensures that it can drive the slider to move.

[0025] The beneficial effects of this utility model are:

[0026] This photovoltaic power generation box-type substation, through the cooperation of a triangular top plate, a U-shaped rod, a movable plate, a threaded rod, a power chamber, a first bevel gear, a second bevel gear, a motor, a groove, a dustproof net, and a slider, ensures that only one motor is needed when cleaning two photovoltaic panels. This reduces the overall power consumption and manufacturing cost of the device. Furthermore, the motor is placed in the groove, which protects it from wind, sun, and rain, and also prevents external dust from contacting the motor, thus making it less prone to damage.
