Description

Technical Field

[0001] This utility model relates to the field of solar power generation technology, specifically a photovoltaic power prediction testing device. Background Technology

[0002] Photovoltaic power prediction testing equipment is commonly used to evaluate and verify the power generation performance of photovoltaic systems. This equipment is crucial to the photovoltaic industry, helping manufacturers verify product performance and providing investors and operators with a reliable basis for projected returns. Simultaneously, these test results also help research institutions and engineers optimize photovoltaic materials and system design, improving energy conversion efficiency.

[0003] In the prior art, the illumination angle of the light source of such devices is fixed and cannot be adjusted according to the geographical location where the photovoltaic panel is installed. Therefore, a photovoltaic power prediction testing device is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a photovoltaic power prediction testing device with advantages such as adjustable sunlight angle. This solves the problem in existing technologies where the light source angle is fixed and cannot be adjusted according to the geographical location of the photovoltaic panel installation.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A photovoltaic power prediction testing device includes a box, a solar simulator and a photovoltaic panel. An arc-shaped ring extending to the right side of the box is rotatably connected inside the box. A worm gear ring is fixedly connected to the top of the arc-shaped ring. A mounting block is slidably connected to the arc-shaped ring on the outside of the arc-shaped ring. A left-right swinging component extending into the mounting block and drivingly connected to the worm gear ring is provided on the right side of the mounting block. A solar simulator is provided at the bottom of the mounting block. A front-back swinging component fixedly connected to the arc-shaped ring is provided on the right side of the box. An inclination adjustment component extending to the front side is provided on the bottom wall of the inner cavity of the box. A photovoltaic panel adapted to the solar simulator is provided on the top of the inclination adjustment component.

[0008] The beneficial effects of this utility model are:

[0009] This photovoltaic power prediction testing device uses a back-and-forth swinging component to drive an arc ring to swing back and forth, which in turn drives a solar simulator to swing back and forth, causing a left-and-right swinging component to rotate. Since the left-and-right swinging component is connected to a worm gear ring transmission, it drives a mounting block to slide outside the arc ring, causing the solar simulator to swing left and right. This allows adjustment of the solar simulator's illumination angle, simulating different angles of sunlight. The tilt adjustment component drives the photovoltaic panel to move, thus adjusting the tilt angle of the photovoltaic panel. The output end of the photovoltaic panel is connected to a power measurement module, which then tests the voltage, current, and power output of the photovoltaic panel. It has the advantage of adjustable sunlight angle.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the left and right swinging assembly includes a first stepper motor and a first worm gear. The right side of the mounting block is provided with a first stepper motor whose output end extends into it. The output end of the first stepper motor is fixedly connected to a first worm gear that is rotatably connected to the left wall of the inner cavity of the mounting block. The first worm gear meshes with a worm gear ring.

[0012] Furthermore, the back-and-forth swing assembly includes a second stepper motor, a second worm gear, and a first worm wheel. The second stepper motor is located on the right side of the housing, and the output end of the second stepper motor is fixedly connected to the second worm gear. The outer side of the right end of the arc ring is fixedly connected to the first worm wheel located on the right side of the housing and meshing with the second worm gear.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the second stepper motor drives the second worm to rotate. Since the second worm meshes with the first worm wheel, it then drives the arc ring to swing back and forth, which in turn drives the solar simulator to swing back and forth. This causes the first stepper motor to drive the first worm to rotate inside the mounting block. Since the first worm meshes with the worm wheel gear ring, it drives the mounting block to slide outside the arc ring, which in turn drives the solar simulator to swing left and right, thereby adjusting the irradiation angle of the solar simulator.

[0014] Furthermore, the tilt adjustment assembly includes a mounting base, a drive shaft, a mounting block, a second worm gear, a third worm, and a third stepper motor. The mounting base is fixedly connected to the bottom wall of the inner cavity of the housing. The drive shaft extending to its right side is rotatably connected inside the mounting base. The mounting block located inside the mounting base is rotatably connected to the outside of the drive shaft. A photovoltaic panel is provided on the top of the mounting block. The second worm gear is fixedly connected to the right end of the drive shaft. The third worm, extending to its front side and meshing with the second worm gear, is rotatably connected inside the housing. The front side of the housing is provided with a third stepper motor mounting base whose output end is fixedly connected to the front end of the third worm.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by driving the third worm gear to rotate through the third stepper motor, and since the third worm gear meshes with the second worm wheel, it then drives the mounting block to rotate in the mounting base through the transmission shaft, thereby adjusting the tilt angle of the photovoltaic panel.

[0016] Furthermore, a one-way glass that communicates with the interior is embedded on the front side of the enclosure.

[0017] The advantage of adopting the above-mentioned further solution is that the internal operating status of the device can be better observed through the one-way glass, avoiding discomfort or glare to the eyes caused by the sunlight simulator. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the embodiments, by Figure 1-3Provided is a photovoltaic power prediction testing device. This utility model includes a housing 1, a solar simulator 2, and a photovoltaic panel 3. The housing 1 has an arc-shaped ring 4 rotatably connected to its right side. The top of the arc-shaped ring 4 is fixedly connected to a worm gear ring 5. The outer side of the arc-shaped ring 4 is provided with a mounting block 6 slidably connected to it. The right side of the mounting block 6 is provided with a left-right swinging component 7 extending into it and drivingly connected to the worm gear ring 5. The bottom of the mounting block 6 is provided with the solar simulator 2. The right side of the housing 1 is provided with a front-back swinging component 8 fixedly connected to the arc-shaped ring 4. The bottom wall of the inner cavity of the housing 1 is provided with a tilt adjustment component 9 extending to its front side. The top of the tilt adjustment component 9 is provided with a photovoltaic panel 3 adapted to the solar simulator 2.

[0024] The left and right swing assembly 7 includes a first stepper motor 701 and a first worm 702. The right side of the mounting block 6 is provided with a first stepper motor 701 whose output end extends into it. The output end of the first stepper motor 701 is fixedly connected to a first worm 702 that is rotatably connected to the left wall of the inner cavity of the mounting block 6. The first worm 702 meshes with the worm gear ring 5.

[0025] The front and back swing assembly 8 includes a second stepper motor 801, a second worm 802 and a first worm wheel 803. The second stepper motor 801 is provided on the right side of the housing 1. The output end of the second stepper motor 801 is fixedly connected to the second worm 802. The outer side of the right end of the arc ring 4 is fixedly connected to the first worm wheel 803 located on the right side of the housing 1 and meshing with the second worm 802.

[0026] The second stepper motor 801 drives the second worm 802 to rotate. Since the second worm 802 meshes with the first worm gear 803, it drives the arc ring 4 to swing back and forth, which in turn drives the solar simulator 2 to swing back and forth. This causes the first stepper motor 701 to drive the first worm 702 to rotate within the mounting block 6. Since the first worm 702 meshes with the worm gear ring 5, it drives the mounting block 6 to slide outside the arc ring 4, which in turn drives the solar simulator 2 to swing left and right, thereby adjusting the irradiation angle of the solar simulator 2.

[0027] The tilt adjustment assembly 9 includes a mounting base 901, a drive shaft 902, a mounting block 903, a second worm gear 904, a third worm 905, and a third stepper motor 906. The mounting base 901 is fixedly connected to the bottom wall of the inner cavity of the housing 1. The drive shaft 902, extending to its right side, is rotatably connected inside the mounting base 901. The mounting block 903, located inside the mounting base 901, is rotatably connected to the outside of the drive shaft 902. A photovoltaic panel 3 is provided on the top of the mounting block 903. The second worm gear 904 is fixedly connected to the right end of the drive shaft 902. The third worm 905, extending to its front side and meshing with the second worm gear 904, is rotatably connected inside the housing 1. The front side of the housing 1 is provided with a mounting base 901 for the third stepper motor 906, whose output end is fixedly connected to the front end of the third worm 905.

[0028] The third stepper motor 906 drives the third worm 905 to rotate. Since the third worm 905 meshes with the second worm wheel 904, it then drives the mounting block 903 to rotate in the mounting base 901 through the transmission shaft 902, thereby adjusting the tilt angle of the photovoltaic panel 3.

[0029] The front side of the enclosure 1 is fitted with a one-way glass 10 that communicates with its interior;

[0030] The one-way glass 10 allows for better observation of the device's internal operating status, preventing the sunlight simulator 2 from causing discomfort or glare to the eyes.

[0031] Working principle:

[0032] Step 1: The second stepper motor 801 drives the second worm 802 to rotate. Since the second worm 802 meshes with the first worm gear 803, it drives the arc ring 4 to swing back and forth, which in turn drives the solar simulator 2 to swing back and forth. This causes the first stepper motor 701 to drive the first worm 702 to rotate within the mounting block 6. Since the first worm 702 meshes with the worm gear ring 5, it drives the mounting block 6 to slide outside the arc ring 4, which in turn drives the solar simulator 2 to swing left and right, thereby adjusting the irradiation angle of the solar simulator 2.

[0033] The second step is to drive the third worm 905 to rotate through the third stepper motor 906. Since the third worm 905 meshes with the second worm wheel 904, it then drives the mounting block 903 to rotate in the mounting base 901 through the transmission shaft 902, thereby adjusting the tilt angle of the photovoltaic panel 3.

[0034] Step 3: Connect the output terminal of photovoltaic panel 3 to the power measurement module, and then test the voltage, current and power output of photovoltaic panel 3.
