Description
Technical Field
[0001] This utility model relates to the field of electrical control device technology, and in particular to an integrated photovoltaic system electrical control device. Background Technology
[0002] Integrated photovoltaic electrical control equipment is a comprehensive electrical control device designed for photovoltaic power generation systems.

Existing integrated photovoltaic system electrical control devices typically incorporate heat dissipation structures to prevent overheating and ensure normal operation.
[0003] The Chinese patent with authorized publication number CN221353637U uses an exhaust fan for heat dissipation and a cleaning brush for automatic cleaning. However, in actual use, since photovoltaic power stations are generally located in open areas with a lot of dust, the cleaning brush needs to be cleaned frequently. During the cleaning process, if the exhaust fan runs continuously, the dust that has been cleaned will be re-adsorbed onto the dust filter. If the exhaust fan does not run, the heat dissipation efficiency will be reduced, resulting in poor performance. Summary of the Invention

[0023] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention. Example
[0024] Reference Figures 1 to 5 An integrated photovoltaic system electrical control device includes an equipment box 1. A dustproof component 2 is provided on one side of the equipment box 1. A heat dissipation component 4 connected to one side of the dustproof component 2 is provided inside the equipment box 1. A one-way pipe 3 is fixedly connected to the other side of the equipment box 1 and is connected to the inside of the equipment box 1. The air inside the equipment box 1 can be discharged to the outside through the one-way pipe 3. Since the one-way pipe 3 is unidirectional, it can allow outside air to enter the equipment box 1. The dustproof component 2 is used to remove sand and dust from the air, and the heat dissipation component 4 is used to blow air into the equipment box 1 for heat dissipation. Temperature sensors are provided in all electrical equipment installed inside the equipment box 1.
[0025] The dustproof component 2 includes a mounting housing 21 fixedly connected to one side of the equipment box 1. A collection box 22 and a third electric telescopic rod 29 are fixedly connected to the lower end of the mounting housing 21. A guide plate 23 is fixedly connected to the lower end of the third electric telescopic rod 29, and the guide plate 23 is in contact with the inner wall of the collection box 22. The upper end of the guide plate 23 is inclined. An installation assembly 24 is installed inside the mounting housing 21. Two sets of dust removal components 26 are installed vertically through the installation assembly 24. A first electric telescopic rod 25 is fixedly connected to the inner wall of one side of the mounting housing 21, and the dust removal components 26 are connected via the third electric telescopic rod 29. The telescopic mechanism controls the contact and separation between the guide plate 23 and the collection box 22. When the collection box 22 separates from the guide plate 23, the dust accumulated on the guide plate 23 can slide down along the guide plate 23 due to the inclined upper end of the guide plate 23, thereby cleaning the inside of the collection box 22. The continuous extension and retraction of the third electric telescopic rod 29 causes the guide plate 23 to vibrate vertically, which can promote the falling of dust and improve cleaning efficiency. The rapid extension and retraction of the first electric telescopic rod 25 to strike the mounting component 24 can cause the mounting component 24 and the two sets of dust removal components 26 to vibrate.
[0026] The mounting assembly 24 includes a fixed housing 241 fixedly connected to the inner wall of the lower end of the mounting housing 21. The upper end of the fixed housing 241 is fixedly connected to a mounting housing 242 and a guide housing 243 at a distance. Two sets of dust removal assemblies 26 are disposed between the mounting housing 242 and the guide housing 243. The upper and lower ends of the fixed housing 241 are provided with two sets of clearance holes 244 for the dust removal assembly 26 to move. The mounting housing 242 and the guide housing 243 are used to guide the dust removal assembly 26.
[0027] The lower inner wall of the fixed housing 241 is fixedly connected with a first guide strip 27 and a second guide strip 28 at intervals. The upper end of the first guide strip 27 is inclined to one side, and the upper end of the second guide strip 28 is inclined to both sides. The first guide strip 27, the second guide strip 28 and the two sets of dust removal components 26 are arranged alternately. The first guide strip 27 and the second guide strip 28 are used to guide the dust.
[0028] The dust removal assembly 26 includes a motor 261 fixedly connected to the inner wall of the upper end of the mounting housing 242 and a lead screw 262 fixedly connected to the lower end of the motor 261. The lower end of the lead screw 262 is rotatably connected to the inner wall of the mounting housing 242. A threaded block 263 is threadedly connected to the outer surface of the lead screw 262, and the threaded block 263 is slidably connected to the inner wall of the mounting housing 242. The motor 261 can control the threaded block 263 to move up and down along the lead screw 262.
[0029] A mounting frame 264 is fixedly connected to one side of the threaded block 263, and the two sides of the mounting frame 264 are slidably connected to the mounting housing 242 and the guide housing 243, respectively. A rubber layer is provided on the outer surface of the upper and lower ends of the mounting frame 264, and a filter screen 265 is fixedly connected to the inner side of the mounting frame 264. The two sets of mounting frames 264 are respectively set between the mounting housing 242 and the guide housing 243 and inside the fixed housing 241. Under the drive of the threaded block 263, the height of the mounting frame 264 and the filter screen 265 can be controlled by the motor 261. When the rubber layer contacts the clearance hole 244, a seal can be achieved to prevent air circulation.
[0030] A second electric telescopic rod 266 is fixedly connected to the inner wall of one side of the fixed housing 241. A strip brush 267 is fixedly connected to one end of the second electric telescopic rod 266, and the strip brush 267 is in contact with one side of the filter screen 265. The second electric telescopic rod 266 can drive the strip brush 267 to move back and forth on the filter screen 265, thereby brushing off the impurities remaining on the filter screen 265.
[0031] The heat dissipation assembly 4 includes a support pipe 44 that is fixedly connected to one side of the mounting housing 21 and a fan 45 that is fixedly connected inside the support pipe 44. One end of the support pipe 44 is fixedly connected to a connecting hose 43, and one end of the connecting hose 43 is connected to the inside of the equipment box 1. The support pipe 44 is used to support the fan 45, and the fan 45 can deliver air to the inside of the connecting hose 43.
[0032] A linear slide 41 is fixedly connected to the inner wall of one side of the equipment box 1. An air outlet pipe 42 is provided on one side of the linear slide 41. Multiple sets of air outlet holes are opened on the outer surface of the air outlet pipe 42, and the air outlet holes face the integrated electrical control equipment inside the equipment box 1. One end of the air outlet pipe 42 is fixedly connected to the connecting hose 43. The connecting hose 43 is provided with sufficient length for the air outlet pipe 42 to move. The air outlet pipe 42 can be moved up and down in the vertical direction by the linear slide 41, thereby expanding the air outlet area and improving the heat dissipation effect. The connecting hose 43 is used to connect the support pipe 44 and the air outlet pipe 42. All electrical structures of this device are electrically connected to the controller and are controlled by the controller. This is a mature existing technology.
[0033] In use, when the temperature of the integrated electronic control equipment inside the equipment box 1 exceeds a threshold, the fan 45 is activated to deliver air to the exhaust pipe 42. The air is then blown onto the integrated electronic control equipment inside the equipment box 1 for cooling. Simultaneously, the linear slide 41 causes the exhaust pipe 42 to move up and down repeatedly, expanding its exhaust range and reducing heat dissipation dead zones, thereby improving heat dissipation efficiency and effectiveness. When the integrated electronic control equipment experiences localized overheating, the linear slide 41 can adjust the exhaust pipe 42 to a higher-temperature area for targeted heat dissipation, further enhancing the heat dissipation effect. During the operation of the fan 45, when air passes through the filter screen 265, the sand and impurities mixed in the air can be filtered by the filter screen 265, preventing sand and dust from entering the equipment box 1 and affecting the normal operation of the integrated electrical control equipment. After a period of use, some sand and dust accumulate on the filter screen 265. The motor 261 moves the filter screen 265 inside the fixed housing 241 upward a certain distance until it contacts the inner wall of the upper end of the mounting housing 21. Then, another set of motors 261 moves the mounting frame 264 with impurities downward a certain distance until the upper end of the mounting frame 264 with impurities is flush with the upper end of the fixed housing 241. The impact of the first electric telescopic rod 25 causes the fixed housing 241, mounting frame 264, and filter screen 265 to vibrate, dislodging impurities from the filter screen 265 onto the first guide bar 27 or the second guide bar 28, thus cleaning the filter screen 265. Subsequently, the motor 261 moves the mounting frame 264 upwards. During this process, the second electric telescopic rod 266 drives the brush 267 to clean the filter screen 265, further removing impurities. Simultaneously, dust accumulated on the first guide bar 27 or the second guide bar 28 is swept away by the brush 267 during the vibration. The filter screen 265 is cleaned by falling into the collection box 22 and then moving downwards to reset the mounting frame 264 via the motor 261. After a period of use, the impurities inside the collection box 22 can be discharged by extending and retracting the third electric telescopic rod 29. This invention can not only dissipate heat from the integrated electronic control equipment inside the equipment box 1, but also remove dust from the blown-in air. With the setting of two sets of dust removal components 26, cleaning can be carried out alternately. No manual operation or cooling needs to be stopped during cleaning, and the dust removed will not re-adhere, effectively improving the efficiency and effect of cleaning.
