Description

Technical Field

[0001] This invention relates to the field of solar energy control system technology, specifically to an MPPT controller that is easy to maintain. Background Technology

[0002] The MPPT controller monitors the output voltage and current of the photovoltaic panel and adjusts them according to the lighting conditions to make it work at the maximum power point, thereby maximizing the energy conversion efficiency of the photovoltaic system. It is widely used in new energy fields such as solar photovoltaic systems, wind power systems, and hybrid energy systems, and is a key device for improving the utilization rate of renewable energy and system efficiency.

[0003] However, existing MPPT controllers still have the following drawbacks:

[0004] First, the internal components of existing MPPT controllers are generally concentrated on a small motherboard, and the controller itself is also small in size. This means that if an operator needs to perform internal maintenance, the confined space and surrounding side walls will restrict the operator's movement during maintenance, making the operation difficult and inconvenient. For example, it is not easy to disassemble and replace faulty components, resulting in reduced maintenance efficiency. Due to the limited space, operators may be restricted during maintenance, which may easily lead to misoperation or improper operation, increasing the risk of accidents during maintenance, such as accidentally touching other components or circuits and causing secondary damage. In addition, it is not possible to fully ensure that the connections of components are secure or the contacts of circuits are good, thereby affecting the performance and stability of the equipment and leading to a decline in quality.

[0005] Secondly, after prolonged use, the main circuit board inside the MPPT controller may experience reduced efficiency due to aging. Therefore, it is necessary to test the performance of the circuit board. However, there are many controllers in a photovoltaic panel, and the detection pins connected to the circuit board are fixed, resulting in a time-consuming and inefficient testing process. In large-scale photovoltaic systems, this makes the maintenance and troubleshooting process of the entire system very slow. In addition, due to the low efficiency, the time and manpower costs required to test each MPPT controller will increase. In the long run, this may lead to a significant increase in maintenance costs and affect the economic benefits of the photovoltaic system.

[0006] Finally, after prolonged operation, the internal components of the MPPT controller will inevitably generate heat, and dust will accumulate on their surfaces, especially in the gaps. This dust accumulation in the gaps of important components, including switches, leads to poor heat dissipation, causing internal heat buildup, which in turn increases the internal temperature of the controller. Excessive temperature affects the stable operation of the circuit board components and may even increase the risk of equipment damage. Dust accumulation will increase the workload of the internal components of the controller and shorten the lifespan of the controller. Summary of the Invention

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0016] Furthermore, the cleaning mechanism is provided in two sets and symmetrically distributed on the upper and lower sides of the upper half of the outer shell. The cleaning mechanism includes a worm gear, which is fixedly connected to the side of the fan near the lower half of the outer shell. The other end of the worm gear passes through the side wall of the lower half of the outer shell and is located inside the lower half of the outer shell. The end of the worm gear away from the main component is meshed with a gear, and a support plate is fixedly connected to the lower surface of the gear.

[0017] Furthermore, the length of the support plate is adapted to the diameter of gear one, and a connecting rod one is rotatably connected to one end of the support plate. A connecting rod two is rotatably connected to the end of the connecting rod one away from the fan. Both the connecting rod two and the connecting rod one are horizontally arranged. The end of the connecting rod two near gear one is rotatably connected to the lower half of the outer shell, and the end of the connecting rod two away from gear one is fixedly connected to the brush.

[0018] Furthermore, the pop-out mechanism is provided in two sets and symmetrically distributed on the left and right sides of the main component. The pop-out mechanism includes an inclined quadrilateral bracket, the top of which is rotatably connected to a shelf, and a folding rod is rotatably connected to the end of the shelf near the storage box. The top of the folding rod is rotatably connected to the side wall of the upper shell.

[0019] Furthermore, a second gear is fixedly connected to the top of the first gear, and the second gear meshes with the chain. Positioning holes are evenly distributed on the upper surface of the chain.

[0020] Furthermore, the detection mechanism includes a first helical tooth, which is rotatably connected to the bottom end of a quadrilateral bracket. The side of the first helical tooth away from the shelf is engaged with a second helical tooth. The second helical tooth is rotatably connected to the side wall of the lower half of the outer shell. A sliding shaft is fixedly connected to the middle of the second helical tooth. A telescopic rod is slidably connected to the surface of the sliding shaft. The first telescopic rod is horizontal.

[0024] (III) Beneficial Effects

[0025] Compared with known prior art, the technical solution provided by this invention has the following beneficial effects:

[0026] 1. The device is equipped with a worm gear, connecting rod 1, and a brush. The worm gear meshes with gear 1, which rotates and drives connecting rod 1 and connecting rod 2 to oscillate back and forth. During the oscillation, the brush cleans the dust from the surface of the main components. This device can clean the internal motherboard, preventing excessive dust accumulation that could cause components to overheat. It sweeps out all the dust blocking the gaps in important components, effectively improving heat dissipation efficiency, preventing excessive internal heat accumulation that could reduce the stability and efficiency of the controller, reducing the risk of equipment damage, and extending its service life.

[0027] 2. By incorporating a quadrilateral bracket and a folding rod, opening the lower half of the outer shell causes the folding rod to unfold from a folded position, simultaneously raising the shelf. The shelf then causes the quadrilateral bracket at the bottom to rise from a flattened position, moving the shelf and main components to the outside of the upper half of the outer shell. This device can move the mainboard components, originally stored inside the controller, to the outside, allowing operators to perform maintenance on the mainboard without having to operate within the confined space of the controller. The maintenance process is no longer difficult or inconvenient. Specifically, faulty components can be easily disassembled and replaced, greatly improving maintenance efficiency. It is no longer limited by space, avoiding accidental contact and preventing secondary damage. It also ensures that the components are connected securely enough, without affecting the stability of the equipment.

[0028] 3. With a hollow frame, plug, and positioning rod, the telescopic rod one moves on a chain, and the positioning rod fixed at the top intermittently inserts into the positioning hole. At the same time, the plug at the top and the telescopic rod two also continuously extend and shorten. Its extension and contraction are controlled by the insertion of the inclined boss and groove. The interface is tested during the extension and contraction cycle. This device can perform performance testing on the pin sockets of the main boards inside the controller. The intermittent testing using automatic conveying equipment can effectively deal with the inconvenience of manual testing due to the large number of internal pins. The automatic testing equipment can prevent the negative effects of long testing time and low efficiency. Especially in large photovoltaic systems, it can make the maintenance and troubleshooting process faster and reduce maintenance costs. Attached Figure Description

[0058] As a preferred embodiment of this example, Figure 1 - Figure 15As shown, the pop-out mechanism 300 is provided in two sets and symmetrically distributed on the left and right sides of the main component 106. The pop-out mechanism 300 includes an inclined quadrilateral bracket 301. The top of the quadrilateral bracket 301 is rotatably connected to the shelf 105.

[0059] In this embodiment, as Figure 1 - Figure 15 As shown, a gear 203 is fixedly connected to the top of gear 202. Gear 203 and chain 304 are meshed together. Positioning holes 305 are evenly provided on the upper surface of chain 304.

[0060] Compared with existing technologies, this device can move the motherboard components that were originally stored inside the controller to the outside, allowing operators to perform maintenance on the motherboard without having to operate it inside the confined space of the controller. The maintenance process is no longer difficult or inconvenient. Specifically, faulty components can be easily disassembled and replaced, greatly improving maintenance efficiency. It is no longer limited by space, which can prevent accidental contact and other situations, thus preventing secondary damage. It can also ensure that the components are connected securely enough, without affecting the stability of the equipment.

[0061] In this embodiment, as Figure 1 - Figure 15 As shown, a detection structure is proposed. The detection mechanism 400 includes a detector 408 that displays interface detection data. The detector 408 is disposed in the inner cavity of the upper half shell 101 and close to the upper and lower ends.

[0062] In this embodiment, as Figure 1 - Figure 15 As shown, the detection mechanism 400 includes a helical tooth 401, which is rotatably connected to the bottom end of the quadrilateral bracket 301.

[0065] In this embodiment, as Figure 1 - Figure 15 As shown, a contact plate 412 is fixedly connected to the side of the spring 410 near the main component 106. The contact plate 412 is fixedly connected to the bottom end of the plug 407. The size of the contact plate 412 is adapted to the groove direction on the surface of the interface 107.

[0066] Compared with existing technologies, this device can perform performance testing on the pin sockets of the main boards inside the controller. By using the intermittent testing of the automatic conveying equipment, it can effectively deal with the inconvenience of manual testing due to the large number of internal pins. The automatic testing equipment can prevent the negative effects of long testing time and low efficiency. Especially in large photovoltaic systems, it can make the maintenance and troubleshooting process faster and reduce maintenance costs.

[0067] The following is a detailed explanation of the working principle of the above embodiments:

[0068] To repair the controller, you must first open it and expose the motherboard before you can perform any repairs.

[0069] Therefore, the key task is to move the motherboard to the outside. The upper half-shell 101 and the lower half-shell 102 are the front and rear halves of the controller, respectively. They are rotatably connected and together form a sealed space to enclose the internal components. Keeping the lower half-shell 102 stationary, the upper half-shell 101 is manually rotated. Since the upper half-shell 101 and the lower half-shell 102 are rotatably connected, the upper half-shell 101 can be rotated open around the connecting shaft. At this time, the sealed space is opened. The inner wall of the upper half-shell 101 is rotatably connected to the folding rod 302. The folding rod 302 is divided into two folded parts. Its top end is connected to the upper half-shell 101, while the bottom end is rotatably connected to the shelf 105. The main component 106 is fixedly connected inside the shelf 105. The main component 106 controls the entire MPPT to work normally. When the upper shell 101 is rotated and opened clockwise, the upper part of the folding rod 302 is also rotated and lifted upward. The lower part of the folding rod 302 is connected to the shelf 105 and rises upward together. On both sides of the shelf 105, a quadrilateral bracket 301 is rotatably connected. The quadrilateral bracket 301 is in the shape of a parallelogram and can be flexibly extended. Its bottom end is rotatably connected to the lower shell 102. When the shelf 105 and the main component 106 are lifted upward together, since the top of the quadrilateral bracket 301 is rotatably connected to the shelf 105, the two inclined sides of the quadrilateral bracket 301 are also passively changed from a horizontal state to a vertical state.

[0070] Furthermore, since the top movement trajectory of the quadrilateral bracket 301 is arc-shaped, when the shelf 105 and the main component 106 are pulled up by the folding rod 302, they will also be affected by the top movement trajectory of the quadrilateral bracket 301. Under this influence, the shelf 105 will shift towards the storage box 103. The combination of the two trajectories can move both the shelf 105 and the main component 106 out of the interior and out of the interior, making it convenient for maintenance personnel to perform maintenance.

[0071] In the process of repairing the MPPT controller, the key step is to test the interface 107 in the main component 106. By checking whether the connection is established and obtaining data, including the current, battery voltage, and temperature of the main component 106, the performance of the main component 106 is judged. As the shelf 105 and the main component 106 are pulled up by the folding rod 302, the shelf 105 moves to the outside under the influence of the quadrilateral bracket 301. While the inclined side of the quadrilateral bracket 301 rotates, its bottom end is fixedly connected to the helical tooth 401. When the helical tooth 401 rotates, the helical tooth 402 that is meshed with the surface of the helical tooth 401 also rotates. One side of the helical tooth 402 is rotatably connected to the inner wall of the lower half of the outer shell 102, while the other side is fixedly connected to the telescopic rod 403. The helical tooth 402 and the telescopic rod 403 rotate together under the drive of the helical tooth 401.

[0072] In the initial position, the telescopic rod 403 and the various components connected to its top are horizontal and separated from the interface 107 on the main component 106 by a certain distance. Driven by the helical gear 402, the telescopic rod 403 rotates from a horizontal state to a vertical state. Since the helical gear 402 is engaged with the helical gear 401, the helical gear 401 is rotated by the quadrilateral bracket 301. However, when the side of the quadrilateral bracket 301 rotates to a completely upright position, the quadrilateral bracket 301 is restricted by the upper shell 101 and can no longer rotate, so that the rotation angle of the side of the quadrilateral bracket 301 is a right angle. Therefore, after a series of transmissions, the telescopic rod 403 connected by the helical gear 402 rotates by a right angle.

[0073] The top of the telescopic rod 403 is fixedly connected to the hollow frame 404. As the telescopic rod 403 changes from horizontal to vertical, the hollow frame 404, the plug 407 connected to the hollow frame 404, and the detector 408 also change from a horizontal to a vertical state. After rotating 90 degrees, the plug 407 rotates from the bottom to the air and becomes vertical. The height of the plug 407 is consistent with the height of the interfaces 107 on both sides of the main component 106. However, at this time, the plug 407 is not yet inserted into the interface 107, but only temporarily touches the upright frame around the interface 107, waiting for detection.

[0074] After removing the main component 106 and the shelf 105 from the inside, the main component 106 will inevitably generate heat due to prolonged use. During maintenance, this heat needs to be dissipated. At this time, the operator manually starts the fan 104 located in the storage box 103. The storage box 103 is semi-enclosed, and the fan 104 is controlled from the outside via a switch. The blades of the fan 104 rotate, blowing air into the upper half of the outer shell 101 and the lower half of the outer shell 102 to cool the main component 106. Simultaneously, a worm gear 201 is fixedly connected to the side of the main component 106 near the upper half of the outer shell 101. The worm gear 201 meshes with a gear 202, and the lower surface of the gear 202 is fixed... A support plate 203 is connected. Under the meshing of the worm gear 201, the gear 1 202 and the support plate 203 rotate. At the same time, one end of the support plate 203 is rotatably connected to the connecting rod 1 204, and the other end of the connecting rod 1 204 is rotatably connected to the connecting rod 2 205 and the brush 206. Under the rotation of the support plate 203, the connecting rod 1 204 will swing. The end of the connecting rod 2 205 away from the brush 206 is rotatably connected to the lower half of the outer shell 102. So the final effect is that the connecting rod 2 205 and the brush 206 swing back and forth with the connection point with the lower half of the outer shell 102 as the center under the action of the connecting rod 1 204. During the swinging process of the brush 206, the dust accumulated on the surface of the main component 106 can be swept and cleaned.

[0075] In addition, while gear 1 202 rotates, gear 2 303 is fixedly connected to the top of gear 1 202. The surfaces of the two gears 2 303 are meshed with a chain 304. The length of the chain 304 is the same as the length of the shelf 105. If the length of the chain 304 is less than the length of the shelf 105, the moving area of ​​the detection component moving on the chain 304 cannot penetrate the left and right sides of the shelf 105, and therefore cannot completely cover the interface 107 on the main component 106. Only when the length of the chain 304 is equal to or greater than the shelf 105 can the interface 107 on the main component 106 be fully inspected. Positioning holes 305 are evenly distributed on the upper surface of the chain 304. The spacing of the positioning holes 305 is the same as the spacing of the interface 107 on the main component 106. Consistent spacing ensures accurate performance testing of interface 107. Only when positioning hole 305 and interface 107 are aligned can subsequent steps be guaranteed. Previously, plug 407 and tester 408 had changed from a flat position to a vertical position, and plug 407 had contacted the upright frame around interface 107. Telescopic rod 403 is fixedly connected to positioning rod 411. Telescopic rod 403 can extend and retract. Positioning rod 411 is connected to the upper part of telescopic rod 403. Positioning rod 411 is at a right angle. Initially, positioning rod 411 and telescopic rod 403 are horizontal. When it becomes vertical, positioning rod 411 also becomes vertical, and its bottom end can be inserted into positioning hole 305 on the surface of chain 304 with the help of the rotation force of telescopic rod 403. After insertion, the positioning rod 411 can move together with the chain 304. At the same time, the helical tooth 402 and the telescopic rod 403 are connected by a sliding shaft 413, which can slide on the sliding shaft 413. This means that when the chain 304 rotates, the telescopic rod 403 can move together with the chain 304.

[0076] In the initial state, the plug 407 is not inserted into the interface 107, and the spring 410 is in a compressed state. At the same time, the inclined boss 405 is also inserted and engaged with the groove 409. The engagement of the inclined boss 405 and the groove 409 can limit the length of the telescopic rod 406 within a certain range and keep it in a shortened state. In this shortened state, the plug 407 and the interface 107 are not in contact.

[0077] Next, the positioning rod 411 is inserted into the chain 304, and the telescopic rod 403 moves together with the positioning hole 305. When the telescopic rod 403 causes the plug 407 and the detector 408 to stand upright, the plug 407 cannot be directly inserted into the interface 107 because the contact platform 412 is fixedly connected below the plug 407. The contact platform 412 will abut against the baffle 108 around the interface 107. Since the length of the object is longer than the plug 407, the plug 407 cannot be inserted into the interface 107. Directly below each interface 107, the baffle 108 has a recessed notch that can fit the protrusion. The size of the recess is just enough to allow the protrusion below the plug 407 to insert into it. When the telescopic rod 403 slides on the sliding shaft 413, causing the plug 407 to move to the position of the interface 107, the protrusion below the plug 407 inserts into the recess below the baffle 108. At this time, under the elastic force of the top spring 410, the plug 407 is pressed into the interface 107, so that the plug 407 and the interface 107 are inserted. At the same time, the telescopic rod 406 also becomes longer. The detector 408 connected to the other end of the telescopic rod 406 can display various data of the interface 107 and the main component 106, reflecting the working performance. There is only one plug 407. The plug 407 and the detector 408 are connected and tested to multiple interfaces 107 in sequence as they move with the bottom chain 304.

[0078] When the plug 407 is inserted into the interface 107, the telescopic rod 406 is extended. Previously, the groove 409 was positioned to engage with the inclined boss 405. However, now that the telescopic rod 406 is extended, the relative position of the groove 409 changes, disengaging from the inclined boss 405. The inclined boss 405 moves away from the groove 409 and rises to a certain extent. Simultaneously, the hollow frame 404, fixedly connected to the inclined boss 405, also causes the telescopic rod 403 to rise. The telescopic rod 403 is stretched, and the top of the telescopic rod 403 is stretched. Since the upper part of the telescopic rod 403, that is, the extended part of the telescopic rod 403, is fixedly connected to the positioning rod 411, the positioning rod 411 is also rising. After rising, it disengages from the positioning hole 305. At this time, although the chain 304 is still rotating, the positioning rod 411 is no longer in contact after leaving the positioning hole 305. At this time, the chain 304 and the positioning rod 411 are two unrelated objects and are not affected.

[0079] After the data detection by the detector 408 is completed, the telescopic rod 403 needs to be moved further to detect the next interface 107. At this time, the operator manually presses the hollow frame 404 at the top, causing it to descend. The hollow frame 404 will then lower the inclined boss 405, causing it to re-engage with the groove 409. When the inclined boss 405 re-engages with the groove 409, the telescopic rod 406 is affected. Due to the orientation of the groove 409, when the inclined boss 405 is inserted, a resistance force is generated, compressing and shortening the telescopic rod 406. The shortening of the telescopic rod 406 will disengage the plug 407 inserted into the interface 107, while simultaneously compressing and accumulating elastic force again in the release spring 410. When the plug 407... After completely separating from interface 107, the hollow frame 404 also compresses a certain distance, and the telescopic rod 403 and positioning rod 411 also descend a certain distance. At this time, the positioning rod 411 will descend to re-insert with the chain 304 and positioning hole 305. When the positioning rod 411 is inserted into the positioning hole 305 again, the two are combined into a whole. At this time, the plug 407 has completely separated from interface 107. Under the influence of the lower chain 304, the telescopic rod 403 and plug 407 start to move to the next interface 107 again. During the middle of the movement, although the spring 410 has elasticity, the contact platform 412 at the bottom of the plug 407 will always abut against the baffle 108 to prevent the plug 407 from popping out, until it moves to the next interface 107. The contact platform 412 is inserted into the groove under the baffle 108, allowing the plug 407 to pop into the interface 107.

[0080] The above process will then be repeated until all tests are completed.
