Description

Technical Field

[0001] The present application relates to the technical field of grid-connected boxes, and in particular to an outdoor grid-connected box. Background Art

[0002] As a key component of a photovoltaic power station, the outdoor grid-connected box plays a vital role in the photovoltaic power generation system near the user's site. Its operating mechanism focuses on the self-generation and self-use of the user side, and transmits the excess electricity to the power grid, which effectively promotes energy self-sufficiency and efficient utilization. The core of the design of the grid-connected box is to ensure the safe and stable operation of the system, realize the harmonious connection between the inverter and the mains power grid, and at the same time improve the overall reliability of the system and the accuracy of power metering.

[0003] In the related art, a grid-connected box used outdoors includes a box body and a box door, wherein a vertical edge on one side of the box door is hinged to the box body, and the other side is detachably connected to the box body through a conventional lock structure; a corresponding mounting cross plate is fixed to the inner wall of the box body by screws, and a related electrical module can be fixed to the mounting cross plate by screws.

[0004] When the grid-connected box is installed outdoors and there are many birds nearby, the birds may excrete feces on the top of the box when flying over. If it is not cleaned for a long time, it may cause corrosion to the upper surface of the box. Since the grid-connected box is often installed at a certain height, the traditional cleaning method - that is, relying on ladders or stools to assist personnel to approach the top of the box for cleaning, is not only time-consuming and labor-intensive, but also requires a lot of preliminary preparation, which greatly reduces the cleaning efficiency. This not only increases the operation and maintenance costs, but may also aggravate the risk of damage to the box due to untimely cleaning. There is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide an outdoor grid-connected box to solve the problem of low efficiency when cleaning the top of the box in the above-mentioned related technologies.

[0006] The outdoor grid-connected box provided in this application adopts the following technical solution: An outdoor grid-connected box comprises a box body and a box door installed on the vertical side of the box body, an exhaust port is provided on the vertical side of the box door; a base plate is fixedly provided on the side of the box body away from the box door, the base plate is flush with the outer edge of the box body, and extension plates are fixedly provided on two opposite vertical sides of the base plate, and a plurality of fixing holes are provided on the extension plates; a fixing plate is hingedly provided on the middle part of the upper side of the base plate, a scraper is fixed on the side of the fixing plate facing the base plate, a connecting rod is ball-jointed at the end of the fixing plate away from the base plate, and a holding rod is ball-jointed at the end of the connecting rod; a limiting notch is provided on the extension plate in the vertical direction for the connecting rod to be inserted, a limiting piece is provided at the lower part of the base plate for limiting the holding rod, and the holding rod can drive the scraper to clean the upper side of the box body through the connecting rod when controlled.

[0007] By adopting the above technical solution, the grid-connected box can be easily fixed on the wall through the design of the base plate, extension plate and fixing holes. At the same time, the hinged and ball-jointed connection of the cleaning component makes the installation and maintenance process simpler and faster. The grid-connected box is designed with a convenient cleaning component. The user only needs to operate the grip rod to use the scraper driven by the connection rod and the fixing plate to clean the upper side of the box. This design avoids the tedious process of relying on ladders or stools to assist personnel to approach the top of the box for cleaning in the traditional cleaning method, greatly improving the cleaning efficiency and reducing the operation and maintenance costs.

[0008] Optionally, the limiting member includes a plurality of protruding blocks fixed to the lower side of the substrate, and a plurality of the protruding blocks are fixed with a bending rod located below the box body and parallel to the lower side of the box body; the plurality of bending rods are parallel to each other, and a clearance gap is provided between the bending rod and the bottom side of the box body for the gripping rod to rotate and engage, and the gripping rod can rotate to the bottom of the substrate along the clearance gap.

[0009] By adopting the above technical solution, the clearance gap formed between the bending rod and the bottom side of the box allows the gripping rod to be easily rotated to the bottom of the base plate when needed to achieve a locked state. When it is necessary to unlock for cleaning, the user only needs to simply turn the gripping rod out of the clearance gap to restore it to its free state. This design greatly simplifies the locking and unlocking process and improves the convenience of operation.

[0010] Optionally, a plurality of rollers are fixedly provided on the bottom side of the bending rod away from the box body, and the holding rod can be rotated to the bottom of the box body along the clearance gap to support the bending rod.

[0011] By adopting the above technical solution, when the grid-connected box is moved a short distance in the early stage or needs to be relocated in the later stage, the holding rod can be rotated along the clearance to the bottom of the box to support the bending rod. At this time, the roller can easily roll on various ground surfaces, which is convenient for short-distance movement of the grid-connected box.

[0012] Optionally, an elastic clamping piece is arranged on the outer circumference of the holding rod, and a positioning groove for the elastic clamping piece to be clamped into is formed on the side of the base plate facing the bending rod.

[0013] By adopting the above technical solution, the matching design of the elastic clamping piece and the positioning groove can ensure the stability of the gripping rod in the locked state. When the elastic clamping piece is clamped into the positioning groove, it prevents the gripping rod from being loosened or falling off accidentally, thereby ensuring the safety and reliability of the cleaning operation.

[0014] Optionally, the box body is provided with a protective cover with an opening facing downward at the outer edge of the exhaust port.

[0015] By adopting the above technical solution, although the protective cover blocks the exhaust port to a certain extent, its downward opening design can ensure that the heat or moisture generated inside the box will not be excessively blocked when it is discharged. At the same time, the protective cover can also play a certain degree of diversion effect, so that the heat or moisture can be discharged from the box more smoothly, thereby improving the exhaust efficiency.

[0016] Optionally, the outer side surface of the box body is slidably provided with control rods located on both sides of the protective cover in the vertical direction, and the outside of the box body is provided with a blocking plate located below the protective cover, and the blocking plate is provided with a plurality of blocking holes; the two ends of the blocking plate are respectively fixedly connected to the sides of the two control rods close to each other, and the outside of the box body is provided with a pushing member for driving the blocking plate to slide upward to seal the protective cover, and a resetting member for sliding downward to release the blocking of the protective cover.

[0017] By adopting the above technical solution, the user is allowed to flexibly adjust the position of the blocking plate according to the external environmental conditions. In humid or rainy weather, the blocking plate can be slid upward by the pusher to block the lower opening of the protective cover, which can effectively prevent rain or other humid substances from entering the box and protect the electrical components from damage. On the contrary, in dry or hot weather, the blocking plate can be slid downward by the reset member to release the blockage, which can ensure that the hot air inside the box is discharged smoothly and maintain the normal operation of the equipment.

[0018] Optionally, the pushing member includes a push plate located outside the box body, and the lower ends of the two control rods are fixedly connected to the side surface of the push plate; a guide slope is provided on the side edge of the push plate away from the control rod, and the holding rod can squeeze the push plate upward along the guide slope when rotating in the clearance gap, and the holding rod is misaligned with the push plate when rotating along the clearance gap to the bottom of the base plate.

[0019] By adopting the above technical solution, the design realizes the linkage between the holding rod and the push plate. When the holding rod rotates in the clearance gap, it can squeeze the push plate along the guiding slope, thereby driving the blocking plate to slide upward and block the lower opening of the protective cover; the ingenious design between the push plate, control rod and holding rod makes the whole structure compact and reasonable. This layout not only saves space, but also makes the appearance of the grid-connected box more neat and beautiful. At the same time, the compact structure also helps to improve the stability and reliability of the equipment.

[0020] Optionally, a filter screen is fixedly provided on the side of the blocking plate facing the protective cover, and the hole size of the filter screen is smaller than the size of the blocking hole.

[0021] By adopting the above technical solution, the filter screen serves as an additional barrier, which can effectively prevent small foreign particles from the outside (such as dust, insects, fibers, etc.) from entering the interior of the box through the blocking holes. These foreign particles may contaminate or damage the electrical components inside the box, thereby affecting the normal operation of the grid-connected box. Therefore, the presence of the filter screen improves the protection performance of the grid-connected box. Since the filter screen is fixedly installed on the blocking plate and is located outside the box, users can easily clean and maintain it. When the filter screen is blocked by pollutants, users only need to remove it and clean it to restore its filtering performance. This design reduces the maintenance difficulty and cost.

[0022] Optionally, the reset member includes a spring in a compressed state, a guide block fixedly installed outside the box, and a baffle fixedly installed on the outer periphery of the control rod. A guide hole for the control rod to penetrate and slide is provided on the guide block. The baffle is located below the guide block, and the two ends of the spring are respectively fixedly connected to the side surfaces of the baffle and the guide block close to each other.

[0023] By adopting the above technical solution, when it is necessary to release the blockage of the protective cover by the blocking plate, first release the pushing of the blocking plate by the pushing member, and then the elastic potential energy stored in the spring in the compressed state will be released, pushing the baffle and the control rod to slide downward. This process does not require an external power source or manual operation, realizing the automatic reset of the blocking plate and improving the convenience and efficiency of operation.

[0024] Optionally, the outer peripheral surface of the connecting rod is an arc surface.

[0025] By adopting the above technical solution, when it is necessary to rotate and snap the connecting rod into the limiting notch, since the outer peripheral surface of the connecting rod is an arc surface, the arc surface design enables the connecting rod to be more easily aligned with the limiting notch when approaching it; due to the natural guiding property of the arc surface, it can help the connecting rod gradually adjust its direction during the rotation process until it is successfully snapped into the limiting notch. This reduces the operation difficulty and time and improves the installation and disassembly efficiency.

[0026] In summary, the present application includes the following beneficial technical effects: The grid-connected box is designed with a convenient cleaning component. Users only need to operate the holding rod to drive the scraper driven by the connecting rod and the fixing plate to clean the upper side of the box. This design avoids the cumbersome process of relying on ladders or stools to assist personnel to approach the top of the box for cleaning in the traditional cleaning method, greatly improves the cleaning efficiency, and reduces the operation and maintenance cost.

A substrate 3 is fixedly provided on the side of the box body 1 away from the box door 2 by screws. The outer edges of the substrate 3 and the box body 1 are flush. Extension plates 31 are integrally formed on the two opposite vertical sides of the substrate 3, and a number of fixing holes 311 are provided on the extension plates 31; when installing this grid-connected box, it is fixed in the positioning holes pre-opened on the wall by screws passing through the fixing holes 311.

[0032] Refer to Figure 2 and Figure 3 , A cleaning assembly 4 is provided outside the box body 1. The cleaning assembly 4 includes a fixing plate 41 hinged to the middle of the upper side of the substrate 3, a scraper 42 fixed to the side of the fixing plate 41 facing the substrate 3. The end of the fixing plate 41 away from the substrate 3 is ball-jointed with a connecting rod 43, and the end of the connecting rod 43 is ball-jointed with a holding rod 44; the outer peripheral surface of the connecting rod 43 is an arc surface, and a limiting notch 312 for the connecting rod 43 to be inserted is provided on the extension plate 31 in the vertical direction. A limiting member 5 for limiting the holding rod 44 is provided at the lower part of the substrate 3. When it is necessary to clean the upper side of the box body 1, the user can first release the limit of the limiting member 5 on the holding rod 44, then hold the holding rod 44, and drive the fixing plate 41 to rotate through the connecting rod 43, so that the scraper 42 cleans the upper side of the box body 1; after cleaning, first turn the connecting rod 43 into the limiting notch 312, and then use the limiting member 5 to limit the holding rod 44 again.

[0033] Refer to Figure 2 and Figure 3 , The limiting member 5 includes two protruding blocks 51 fixed to the lower side of the substrate 3. Bend bars 52 located below the box body 1 and parallel to the lower side of the box body 1 are integrally formed on the two protruding blocks 51; the two bend bars 52 are parallel to each other, and a clearance for the holding rod 44 to rotate and be inserted is provided between the bend bars 52 and the bottom side of the box body 1. When it is necessary to lock and limit the holding rod 44 after cleaning, the user rotates the holding rod 44 along the clearance to the lower side of the substrate 3; when it is necessary to clean and release the locked state of the holding rod 44, the user rotates the holding rod 44 in the reverse direction out of the clearance.

[0034] Refer to Figure 3 and Figure 4Two rollers 53 are fixed on the bottom side of the bending rod 52 away from the box body 1; when the outdoor grid-connected box needs to be moved a short distance, the holding rod 44 can be rotated along the clearance to the bottom of the box body 1 to support the bending rod 52, thereby improving the installation stability of the bending rod 52.

[0035] Reference Figure 4 and Figure 5 Two groups of elastic clips 45 are arranged on the outer periphery of the holding rod 44, wherein the elastic clips 45 include a compression spring 451 and an arc-shaped protrusion 452. A placement groove 441 is provided on the holding rod 44 for the compression spring 451 and the arc-shaped protrusion 452 to be placed. The compression spring 451 presses one side of the arc-shaped protrusion 452 so that a part of the arc-shaped protrusion 452 protrudes out of the opening of the placement groove 441. The protruding part of the arc-shaped protrusion 452 is an arc surface, and the arc length corresponding to the arc surface is a minor arc; a positioning groove 32 is provided on the side of the substrate 3 facing the bending rod 52 for the protruding part of the arc-shaped protrusion 452 to be clamped.

[0036] Reference Figure 6 and Figure 7 A protective cover 13 with an opening downward is fixedly arranged on the outer edge of the exhaust port 11 on the outside of the box body 1, and a protective assembly 6 is arranged on the outside of the box body 1, wherein the protective assembly 6 includes two control rods 63 slidably arranged on the outer side of the box body 1 in the vertical direction, wherein the two control rods 63 are located on both sides of the protective cover 13, and a blocking plate 61 is arranged on the outside of the box body 1 and is located below the protective cover 13, and a plurality of blocking holes are evenly opened on the blocking plate 61; A filter screen 62 is fixedly arranged on the side of the blocking plate 61 facing the protective cover 13. The hole size of the filter screen 62 is smaller than the size of the blocking hole. The two ends of the blocking plate 61 are respectively fixedly connected to the sides of the two control rods 63 close to each other. The outside of the box body 1 is provided with a pusher 64 for driving the blocking plate 61 to slide upward to block the protective cover 13, and a reset member 65 for sliding downward to release the blocking of the protective cover 13. When the outside is humid or rainy, the pushing member 64 can drive the blocking plate 61 to slide upward, thereby blocking the lower opening of the protective cover 13; when the outside is dry or hot, the pushing member 64 is first released, and then the resetting member 65 drives the blocking plate 61 to slide downward and reset, thereby releasing the blockage of the lower opening of the protective cover 13; since the hole size of the filter screen 62 is smaller than the size of the blocking hole, it is used to further filter the gas entering the box body 1 to prevent impurities such as dust and water droplets from entering.

[0037] Reference Figure 7The pushing member 64 includes a pushing plate 641 located outside the box body 1, and the lower ends of the two control rods 63 are fixedly connected to the upper side of the pushing plate 641; a guiding inclined surface 6411 is provided on the side edge of the pushing plate 641 away from the control rod 63, and the holding rod 44 can press the pushing plate 641 upward along the guiding inclined surface 6411 when the making way gap is rotated, and the holding rod 44 is misaligned with the pushing plate 641 when it rotates along the making way gap to the bottom of the substrate 3.

[0038] Reference Figure 7 and Figure 8 The reset member 65 includes a spring 651 in a compressed state, a guide block 652 fixed to the outside of the box body 1, and a baffle 653 fixed to the outer periphery of the control rod 63, wherein the baffle 653 is located below the guide block 652, and a guide hole 6521 is provided on the guide block 652 for the control rod 63 to pass through and slide, and the two ends of the spring 651 are respectively fixedly connected to the side surfaces of the baffle 653 and the guide block 652 that are close to each other; when the holding rod 44 and the push plate 641 are misaligned, the spring 651 in a compressed state is reset, and the baffle 653 is squeezed in the reverse direction, so that the blocking plate 61 slides downward.

[0039] The implementation principle of the embodiment of the present application is: When the upper side of the box body 1 needs to be cleaned, the user can easily operate it. First, by releasing the constraint of the limiter 5 on the holding rod 44, the user can freely hold the holding rod 44. Then, using the linkage effect of the connecting rod 43, the user can rotate the fixing plate 41, thereby driving the scraper 42 to thoroughly clean the upper side of the box body 1. This design not only simplifies the cleaning process, but also improves the cleaning efficiency. After cleaning, the user only needs to insert the connecting rod 43 into the limiting notch 312 and re-fix the holding rod 44 with the limiting member 5 to ensure the stability and safety of the cleaning component 4; When the external environment is relatively humid or rainy, the holding rod 44 rotates along the clearance and squeezes the push plate 641 along the guide slope 6411, driving the blocking plate 61 to slide upward to block the lower opening of the protective cover 13. At this time, the filter screen 62 can prevent impurities such as water droplets from entering the box body 1; When the external environment is dry or hot, first release the squeezing effect of the holding rod 44 on the push plate 641 (for example, by rotating the holding rod 44 to another position), and then the spring 651 is reset, driving the control rod 63 and the blocking plate 61 to slide downward and reset, thereby releasing the blockage of the lower opening of the protective cover 13. At this time, the exhaust port 11 can smoothly discharge the hot air in the box body 1.
