A test box is fixedly installed on one side of the top of the test platform, and a display screen is detachably installed on the other side of the top of the test platform. A floodlight is detachably installed in the center of the top of the test box. This invention utilizes a first push rod motor, a dust collection box, a micro dust pump, a discharge pipe, a floodlight, a base plate, a clamping plate, a display screen, an exhaust fan, a dust collection bag, and a first spring. The clamping plate, in conjunction with the first spring, limits the photovoltaic panel to the base plate.

[0023] Please see Figure 1-4 The present invention provides a technical solution: a photovoltaic tester, including a test platform 1, a test box 2 fixedly installed on one side of the top of the test platform 1, and a display screen 9 detachably installed on the other side of the top of the test platform 1; a floodlight 11 detachably installed in the middle of the top of the test box 2; the test box 2 contains a dust simulation mechanism, a collection mechanism, a limiting mechanism and a discharge mechanism.

[0024] A dust simulation mechanism is installed on one side of the inner cavity of the test chamber 2. The dust simulation mechanism includes a first push rod motor 8, a dust storage box 25, and a micro dust pump 27. The first push rod motor 8 is detachably installed on the outer side of one end near the monitoring mechanism. The input end of the first push rod motor 8 extends movably into the test chamber 2. The output end of the first push rod motor 8 is fixedly connected to a connecting plate 18. The dust storage box 25 is fixedly installed on the top of the connecting plate 18. The micro dust pump 27 is detachably installed on one end of the connecting plate 18. The micro dust pump 27 and the dust storage box 25 are fixedly connected through a connecting pipe. The outlet of the micro dust pump 27 is fixedly connected to an outlet pipe 26.

[0025] The collection mechanism includes an exhaust fan 17 and a dust collection bag 6. The exhaust fan 17 is fixedly connected to the inner wall of the test chamber 2 on the side away from the dust simulation mechanism. An exhaust pipe 5 is fixedly connected to the exhaust port of the exhaust fan 17. The exhaust pipe 5 is fixedly extended to the upper side of the test chamber 2. The dust collection bag 6 is fitted on the outside of the exhaust pipe 5 to collect the dust in a concentrated manner and reuse it.

[0026] The limiting mechanism includes a base plate 15, a clamping plate 16, and a first spring 24. The base plate 15 is fixedly connected to the middle of the bottom of the inner cavity of the test chamber 2. Slide grooves 22 are provided on both sides of the top of the base plate 15, and sliders 23 are movably connected within each of the two slide grooves 22. The clamping plate 16 is fixedly connected to the top of the sliders 23, and the first spring 24 is fixedly connected between the sliders 23 and the inner wall of the slide grooves 22.

[0027] The discharge mechanism includes a door 3, which is hinged to the front end of the test chamber 2.

[0028] In this invention, the photovoltaic panel is positioned on the base plate 15 by means of a first push rod motor 8, a dust collection box 25, a micro dust pump 27, a discharge pipe 26, a floodlight 11, a base plate 15, a clamping plate 16, a display screen 9, an exhaust fan 17, a dust collection bag 6, and a first spring 24. The clamping plate 16, in conjunction with the first spring 24, limits the photovoltaic panel to the base plate 15. Then, while the first push rod motor 8 drives the connecting plate 18 to move, the micro dust pump 27 sprays dust evenly onto the photovoltaic panel. Then, the exhaust fan 17 is activated to collect excess dust in the dust collection bag 6. Then, the floodlight 11 is activated to observe the data on the display screen 9 to determine the quality of the photovoltaic panel and the power output under dust cover. This allows for the simulation of outdoor environmental conditions indoors, thereby improving the quality of the data obtained from photovoltaic panel testing.

[0029] In an optional embodiment, a second push rod motor 19 is fixedly connected to the top of the connecting plate 18, the output end of the second push rod motor 19 extends movably through to the lower side of the connecting plate 18, a drive motor 20 is fixedly connected to the output end of the second push rod motor 19, a cleaning brush 21 is fixedly connected to the motor shaft of the drive motor 20, and an air inlet pipe 7 is fixedly connected to the end of the test box 2 near the first push rod motor 8.

[0030] It should be noted that, through the configuration of the second push rod motor 19, drive motor 20, cleaning brush 21, and air inlet pipe 7, when the photovoltaic panel test is completed, the second push rod motor 19 pushes the cleaning brush 21 to contact the surface of the photovoltaic panel, then the drive motor 20 is started to lift the dust on the surface of the photovoltaic panel, and then the exhaust fan 17 is started in conjunction with the air inlet pipe 7 to introduce gas into the test chamber 2, thereby extracting and collecting the dust in the dust collection bag 6. This not only avoids dust from polluting the working environment, but also allows for the full reuse of the dust.

[0031] In an optional embodiment, a baffle 4 is movably connected to the upper front end of the test chamber 2 via a connecting shaft, and an inner edge 12 is fixedly connected to the inner wall of the outlet of the test chamber 2, with a second spring 13 fixedly connected to the front end of the inner edge 12.

[0032] It should be noted that by setting up the test box 2, inner edge 12, baffle 4 and second spring 13, the baffle 4 is first rotated 180°, then the box door 3 is moved around the hinge and the second spring 13 is compressed, and then the baffle 4 is rotated 180° again and placed in front of the box door 3, so that the box door 3 can be opened quickly.

[0033] In an optional embodiment, a rubber sealing gasket 14 is fixedly connected to the outside of the door 3.

[0034] It should be noted that the rubber sealing gasket 14 increases the sealing between the door 3 and the test chamber 2, thereby preventing a large amount of dust from entering through the gaps and causing contamination on the outside of the test chamber 2.

[0035] In an optional embodiment, a clamp 10 is fitted at the connection between the dust collector bag 6 and the air outlet pipe.

[0036] It should be noted that the clamp 10 allows for easy assembly and disassembly of the dust collector bag 6, thus facilitating the cleaning of the collected dust.

[0037] In use, firstly, by turning the clamping plates 16 in opposite directions, the photovoltaic panel to be tested is placed between the two clamping plates 16. Then, with the spring force of the first spring 24 and the clamping plates 16, the photovoltaic panel is limited on the base plate 15. Then, the baffle 4 is turned 180°, and the box door 3 is turned around the hinge to compress the second spring 13. Then, the baffle 4 is turned 180° again and placed in front of the box door 3 to close the box door 3. Then, the first push rod motor 8 is started to drive the connecting plate 18 to move, and at the same time, the micro dust pump 27 is started to spray the dust in the dust collection box 25 evenly onto the photovoltaic panel. Then, the exhaust fan 17 is started to collect the excess dust in the test box 2 into the dust removal bag 6. Then, the floodlight 11 is started to observe the data on the display screen 9 to judge the quality of the photovoltaic panel and the power under dust cover. In this way, the outdoor environment can be simulated indoors, thereby improving the quality of the photovoltaic panel test data.

[0038] When the test is completed, the second push rod motor 19 pushes the cleaning brush 21 to contact the photovoltaic panel surface. Then, the drive motor 20 is started to make the dust on the photovoltaic panel surface fly up. Then, the exhaust fan 17 is started to enter the test chamber 2 in conjunction with the air inlet pipe 7, so as to extract and collect the dust in the dust collection bag 6. This not only avoids the dust from polluting the working environment, but also allows the dust to be fully reused. Then, the baffle 4 is moved to disengage from the chamber door 3, so that the elastic force of the second spring 13 pushes the chamber door 3 to open automatically. Then, the tested photovoltaic panel is taken out, and the photovoltaic panel test is completed.
