Description

Technical Field

[0001] This invention relates to the field of integrated power supply technology, and in particular to an integrated DC power supply device based on a photovoltaic system. Background Technology

[0002] In the operation and power supply scenarios of photovoltaic systems, it is often necessary to use integrated DC power supply equipment based on photovoltaic systems to rectify, store and stabilize the electrical energy generated by photovoltaic modules. This is to avoid unstable power supply or waste of electrical energy due to fluctuations in photovoltaic output and low power conversion efficiency, which would affect the reliability of photovoltaic system power supply, the operational stability of load equipment and energy utilization efficiency.

[0003] Existing integrated DC power supply equipment based on photovoltaic systems has significant deficiencies in terms of ease of maintenance, safety protection, and dustproof reliability. The bolt-fixed disassembly method requires a cumbersome process involving power outage, wire disconnection, and multi-step loosening. Furthermore, the bolts are prone to corrosion and rust due to environmental factors, further increasing the difficulty of disassembly and extending maintenance time. At the same time, the disassembly process lacks a power-off unlocking mechanism, requiring manual operation of insulated tools and step-by-step power disconnection, which can easily lead to electric shock risks due to operational negligence. In terms of dustproofing, the fixed filters used in the equipment can only achieve basic interception and cannot cope with the continuous accumulation of fine particulate dust in the photovoltaic environment, which is prone to clogging, resulting in reduced heat dissipation efficiency, and even causing equipment overheating shutdown or fire hazards.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides an integrated DC power supply device based on a photovoltaic system. The integrated DC power supply device based on a photovoltaic system includes a main component 1 and an auxiliary component 2.

[0034] Specifically, the main component 1 includes a bottom shell 11, a connector 12 fixed on one side of the bottom shell 11, an adjustment fixing component 13 fixed on the surface of the bottom shell 11, and a magnetic connection shell 14 provided on one side of the bottom shell 11.

[0035] The bottom shell 11 is the core load-bearing structure of the main component 1, providing an installation reference and protective space for the wiring component 12, the adjusting and fixing component 13 and the subsequent auxiliary components 2, preventing internal components from being affected by external impacts and dust interference. The wiring component 12 is used to realize the electrofusion connection between the main component 1 and the external equipment, ensuring that the internal circuit receives a stable power supply. The adjusting and fixing component 13 can adjust the installation position and fixing angle of the bottom shell 11 through telescopic, threaded engagement and other methods to adapt to the installation requirements of different usage scenarios, and provide a certain amount of heat dissipation space by adjusting its position. The magnetic connection shell 14 can cover the subsequent components, which simplifies the installation process and facilitates later disassembly and maintenance, while also helping to enhance the sealing of the sides of the bottom shell 11.

[0036] Specifically, auxiliary component 2 is located on top of main component 1, including a cover plate 21 fitted onto the top of bottom shell 11, an access member 22 on one side of bottom shell 11, a plug-in member 23 that mates with access member 22 fixed on the surface of bottom shell 11, a filter member 24 at the bottom of cover plate 21, the filter member 24 being slidably connected to the inner wall of bottom shell 11, an air blowing member 25 fixed on the top of filter member 24, and a dust collecting member 26 being slidably connected to the inner wall of filter member 24.

[0037] Auxiliary component 2 expands the functionality of the main component 1. The cover plate 21 is fitted onto the top of the bottom shell 11, forming a closed cavity with the bottom shell 11 to further protect the internal components. Simultaneously, its surface heat dissipation structure assists in heat dissipation of the main component 1, maintaining stable internal temperature. The access component 22 and the plug-in component 23 are a collaborative structure: the access component 22 enables the access of external functional modules. During the access process, the plug-in component 23 is triggered by structures such as the irregularly shaped extrusion plate, causing the plug-in component 23 to engage with the plugged-in plate of the cover plate 21, reinforcing the cover plate. The connection stability between component 21 and the bottom shell 11 is ensured. It filters impurities through graded filter holes to prevent impurity accumulation from affecting the operation of the components. The air blowing component 25 is fixed to the top of the filter component 24 and blows away impurities attached to the surface of the filter component 24 through air jet to prevent filter hole blockage and maintain filtration efficiency. The dust collection component 26 is slidably connected to the inner wall of the filter component 24 to collect the impurities intercepted by the filter component 24. When the impurities accumulate to a certain extent, the dust collection component 26 can be pulled out separately for emptying and cleaning without disassembling the entire filter component 24, thus improving maintenance convenience.

[0038] Example 2, refer to Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the adjusting fastener 13 includes a side fixing plate 131 disposed on one side of the bottom shell 11, a side threaded hole 132 fixed on one side of the side fixing plate 131, and a telescopic adjusting rod 133 fixed on the surface of the side fixing plate 131, the telescopic adjusting rod 133 being fixed to one side of the bottom shell 11.

[0040] The side fixing plate 131 provides lateral fixing support for the bottom shell 11. The side threaded hole 132 can be used to insert bolts to realize the fastening connection between the adjusting fastener 13 and the external structure. The telescopic adjustment rod 133 adjusts the relative distance between the side fixing plate 131 and the bottom shell 11 through telescopic movement to adapt to different installation space requirements, while providing certain heat dissipation conditions to ensure that the overall installation position of the bottom shell 11 is accurate and stable.

[0041] Specifically, a first buckle 15 is fixed to the inner wall of the bottom shell 11, and a second fixing rod 16 is fixed to the surface of the bottom shell 11.

[0042] Both the first buckle 15 and the second fixing rod 16 are connection structures between the bottom shell 11 and the cover plate 21. They achieve quick docking of the bottom shell 11 and the cover plate 21 through buckle engagement and rod positioning, while ensuring the sealing and structural stability of the two after connection and avoiding unexpected separation.

[0043] Specifically, the cover plate 21 includes a cover plate body 211 sleeved on the surface of the bottom shell 11, a heat dissipation fin plate 213 fixed on the top of the cover plate body 211, and a heat dissipation connector 214 embedded on the top of the cover plate body 211.

[0044] The cover body 211 covers the bottom shell 11 to form a closed space, protecting the internal components from external interference. The heat dissipation fins 213 accelerate the dissipation of internal heat by increasing the heat dissipation area. The heat dissipation connector 214 can be filled with a heat-conducting medium or connected to the heat dissipation pipes to further improve the heat dissipation efficiency. The two work together to ensure that the internal components of the bottom shell 11 operate at a suitable temperature. At the same time, when disassembling the cover body 211, it provides a certain gripping space for the operator's hands.

[0045] Specifically, the bottom of the cover plate body 211 is fixed with a second buckle 212 that cooperates with the second fixing rod 16. A first fixing rod 218 that cooperates with the first buckle 15 is provided on one side of the second buckle 212. The bottom of the cover plate part 21 is fixed with a plugged plate 215 that cooperates with the plug-in part 23. The bottom of the cover plate part 21 is fixed with a connecting vertical rod 217. The bottom of the connecting vertical rod 217 is fixed with a plug-in spline 216.

[0046] The second buckle 212 engages with the second fixing rod 16, and the first fixing rod 218 engages with the first buckle 15. The double buckle cooperation ensures that the cover plate body 211 is tightly connected to the bottom shell 11. The inserted plate 215 cooperates with the insert 23 to achieve deep fixation between the cover plate 21 and the bottom shell 11. The connecting vertical rod 217 drives the insert spline 216 to dock with the filter element 24, thereby limiting the position of the cover plate 21 on the filter element 24.

[0047] Specifically, the access component 22 includes an access cable 221 disposed on one side of the bottom shell 11, a cable connection end 224 fixed on one side of the access cable 221, a fixing sleeve 222 sleeved on the surface of the access cable 221, and a shaped extrusion plate 223 fixed on the surface of the fixing sleeve 222.

[0048] The access cable 221 enables external signal or power access through the cable connector 224, providing power or transmitting data to the internal components of the bottom shell 11. The irregularly shaped extrusion plate 223 can extrude subsequent components as the access cable 221 is installed, triggering the fixing action of the connector 23, thus achieving the coordination of access and fixing.

[0049] Specifically, the connector 23 includes a movable plate 231 disposed on one side of the bottom shell 11. A connector rod 232 that mates with the connector plate 215 is fixed to one side of the movable plate 231. A movable connecting plate 233 is fixed to one side of the movable plate 231. A first fixed sliding rod 235 is slidably connected to the inner wall of the movable connecting plate 233. A spring piece 234 is disposed on the outer side of the first fixed sliding rod 235. The spring piece 234 is fixed to the surfaces of the movable connecting plate 233 and the bottom shell 11 respectively. A fixed... The base 2311 is fixed to the outside of the bottom shell 11. The top of the base 2311 is fixed with a second fixed slide rod 239. The surface of the second fixed slide rod 239 is fitted with an anti-bending clamping sleeve 2310 that cooperates with the irregular extrusion plate 223. The surface of the anti-bending clamping sleeve 2310 is fixed with a return spring 238. A first extrusion block 237 is fixed to one side of the anti-bending clamping sleeve 2310. A second extrusion block 236 that cooperates with the first extrusion block 237 is fixed to one side of the movable plate 231.

[0050] The irregularly shaped extrusion plate 223 extrudes the anti-bending clamping sleeve 2310, causing it to slide along the second fixed slide bar 239 and compress the return spring 238. This causes the first extrusion block 237 to extrude the second extrusion block 236, pushing the movable plate 231 to move. The movable connecting plate 233 slides along the first fixed slide bar 235. The spring piece 234 provides elastic buffering and return force. The movable plate 231 drives the insertion rod 232 to insert into the inserted plate 215, realizing the insertion and fixing of the cover plate 21 and the bottom shell 11. The return spring 238 and the spring piece 234 ensure that the components can be reset when disassembled, which is convenient for maintenance.

[0051] Specifically, the filter element 24 includes a fixed horizontal plate 245 fixed to the inner wall of the bottom shell 11. A positioning sleeve 247 is fixed to the top of the fixed horizontal plate 245. A plug groove 248 that mates with the plug spline 216 is fixed to the top of the positioning sleeve 247. A connecting spring 246 is sleeved on the surface of the positioning sleeve 247. An inclined filter plate 241 is provided on the top of the connecting spring 246. The top of the inclined filter plate 241 is provided with filter micropores 243 and filter coarse pores 242. A vibration motor 244 is fixed to one side of the inclined filter plate 241.

[0052] The fixed horizontal plate 245 provides an installation base for the positioning sleeve 247. The plug spline 216 is inserted into the plug slot 248 to realize the positioning linkage between the cover plate 21 and the filter element 24. The connecting spring 246 provides elastic support for the inclined filter plate 241 and buffers vibration. The inclined filter plate 241 filters large particles of impurities through the coarse pores 242 and filters fine impurities through the micro pores 243, realizing graded filtration. The vibration motor 244 drives the inclined filter plate 241 to vibrate, preventing impurities from clogging the filter pores and maintaining filtration efficiency.

[0053] Specifically, the air blowing component 25 includes an elastic airbag 251 fixed to the top of the inclined filter plate 241. An embedded one-way air supply valve 253 is embedded in the top of the elastic airbag 251. A connecting pipe 252 is fixed to one side of the elastic airbag 251. An air jet pipe 254 is fixed to the top of the inclined filter plate 241. The connecting pipe 252 is fixed to the top of the air jet pipe 254.

[0054] The embedded one-way air supply valve 253 allows external air to enter the elastic air bladder 251 in one direction, causing the air bladder to expand and store air pressure. When the inclined filter plate 241 vibrates, it compresses the elastic air bladder 251, causing the elastic air bladder 251 to contract. The gas is then transported to the jet pipe 254 through the connecting pipe 252. The jet pipe 254 sprays air in a direction to blow away impurities attached to the surface of the inclined filter plate 241, assisting the filter element 24 in maintaining the filtration effect. It also obliquely blows dust and impurities to ensure that they move to the side closer to the filter coarse holes 242, reducing the frequency of manual cleaning.

[0055] Example 3, referring to Figures 3-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, the dust collection component 26 includes a mounting groove 262 formed at the bottom of the inclined filter plate 241, a mounting slider 263 slidably connected to the inner wall of the mounting groove 262, and a dust collection shell 261 fixed to the bottom of the mounting slider 263.

[0057] When using the cover plate 21, first align the cover plate body 211 of the cover plate 21 with the top of the bottom shell 11 and lower it so that the second buckle 212 at the bottom of the cover plate body 211 is fastened to the second fixing rod 16 of the bottom shell 11, and the first fixing rod 218 is inserted into the first buckle 15, thus completing the initial installation of the cover plate 21.

[0058] Then, pick up the access cable 221 of the access component 22, align the cable connection end 224 with the interface of the bottom shell 11 and insert it. Push the access cable 221 so that the fixing sleeve 222 on the surface moves the irregular extrusion plate 223 closer to the anti-bending clamping sleeve 2310 of the plug-in component 23. The irregular extrusion plate 223 squeezes the anti-bending clamping sleeve 2310, causing it to slide along the second fixed slide rod 239 toward the movable plate 231 and compress the return spring 238, thereby completing the anti-bending protection of the access cable 221.

[0059] When the anti-bending clamping sleeve 2310 moves, the first pressing block 237 on its surface presses the second pressing block 236 of the movable plate 231, causing the movable plate 2310 to slide along the first fixed slide rod 235 through the movable connecting plate 233 and compress the spring piece 234. The insertion rod 232 on one side of the movable plate 231 moves accordingly and is finally inserted into the insertion plate 215 of the cover plate 21, thus locking the cover plate 21. At this time, the connection cable 221 is installed and fixed.

[0060] When disassembling the device, first manually pull out the access cable 221 of the connector 22. At this time, the fixing sleeve 222 on the surface of the cable drives the irregular extrusion plate 223 to disengage from the anti-bending clamping sleeve 2310 of the plug-in 23. The anti-bending clamping sleeve 2310 is reset along the second fixed slide bar 239 under the elastic force of the return spring 238. The first extrusion block 237 on its surface no longer extrudes the second extrusion block 236 of the movable plate 231. The movable plate 231 is reset along the first fixed slide bar 235 under the action of the spring piece 234, which drives the plug-in rod 232 to disengage from the plugged plate 215 of the cover plate 21, releasing the limitation on the cover plate 21. Then, hold the heat dissipation fins 213 on the top of the cover plate body 211 with both hands and pull it up. The second buckle 212 at the bottom of the cover plate body 211 disengages from the second fixing rod 16 of the bottom shell 11, and the first fixing rod 218 disengages from the first buckle 15, thus completing the disassembly of the cover plate 21.

[0061] When the device is placed outdoors, dust and impurities in the air will enter the inner cavity of the bottom shell 11 through the heat dissipation connector 214 of the cover plate 21, and eventually fall onto the surface of the inclined filter plate 241 of the filter element 24. The vibration motor 244 on one side of the inclined filter plate 241 will start, driving the inclined filter plate 241 to vibrate up and down along the positioning sleeve 247. The connecting spring 246 assists in its vibration, preventing the filter micropores 243 and filter coarse pores 242 from being blocked by dust. At the same time, during the vibration, the inclined filter plate 241 will squeeze the elastic air bag 2 of the air blowing element 25. 51. The gas in the elastic airbag 251 is delivered to the jet pipe 254 through the connecting pipe 252. The airflow from the jet pipe 254 blows the dust and impurities on the surface of the inclined filter plate 241 to the lower side. Larger impurities fall through the filter coarse holes 242 and are collected in the inner cavity of the dust collection shell 261 of the dust collection component 26. When cleaning is required, the dust collection shell 261 can be slid out along the mounting groove 262 by the mounting slider 263. The elastic airbag 251 is replenished with gas from the outside through the embedded one-way air replenishment valve 253 to ensure continuous blowing function.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
