Description

Technical Field

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

[0002] As an indispensable part of the modern power system, the importance of outdoor grid-connected boxes lies in their ability to effectively and safely transmit the electric energy from various power generation facilities (such as photovoltaic power stations and wind power stations) to user terminals or directly connect to the power grid. Globally, with the increasing emphasis on low-carbon, sustainable development and the use of clean energy, distributed power generation systems, especially photovoltaic power generation, are facing unprecedented development opportunities. In this context, the role of outdoor grid-connected boxes has become increasingly prominent. It is not only a bridge for power transmission, but also an important guardian of the safe and efficient operation of the entire power generation system, providing multiple protection and monitoring functions.

[0003] Traditional outdoor grid-connected boxes are usually made of metal and have a high level of protection (such as IP54 or higher) to withstand harsh environmental conditions and ensure the safety of internal electrical components. The box cover is flexible in design, with one side hinged to the box body and the other side opened and closed by conventional locks, which is convenient for maintenance and operation. The internal layout is compact, integrating key electrical components such as DC input modules, DC junction boxes, and AC output modules to form a complete power conversion and transmission system. At the same time, in order to improve the heat dissipation efficiency, heat dissipation holes are cleverly opened on the side walls of the box to effectively manage the internal temperature.

[0004] However, in the hot and humid southern regions, especially during the rainy season, this design faces challenges. Frequent rainfall and high humidity can cause rain and water vapor to penetrate through the heat dissipation holes and invade the interior of the box, posing a potential threat to the precision electrical modules. The intrusion of water vapor may not only cause electrical faults such as short circuits and corrosion, but also accelerate component aging, seriously affecting the performance stability and service life of the grid-connected box, so there is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide an outdoor waterproof grid-connected box to solve the problem in the above-mentioned related technologies that rainwater and water vapor may penetrate through the heat dissipation holes, invade the interior of the box and affect the performance of the electrical module.

[0006] The present application provides an outdoor waterproof grid-connected box adopting the following technical solution: An outdoor waterproof grid-connected box, comprising a box body and a box door installed on the box body. A plurality of heat dissipation openings are provided on two opposite vertical side surfaces of the box body, and a guide cover with an upward opening is fixedly provided on the inner edge of the heat dissipation opening on the box body; a substrate is provided below the box body, and a plurality of vertical rods are fixedly provided on the substrate, and the upper end parts of the vertical rods are fixedly connected to the bottom side surface of the box body; a partition board located above the guide cover is slidably provided on the inner wall of the box body. A plurality of blocking holes are provided on the partition board, and a water-absorbing cotton is fixedly provided. Both ends of the partition board are fixedly provided with connecting rods that penetrate through the bottom of the box body and extend to the outside of the box body, and a control component for driving the connecting rods to slide up and down is provided on the substrate. When the partition board slides up and down synchronously with the connecting rods, the opening of the guide cover can be blocked.

[0007] By adopting the above technical solution, a guide cover with an upward opening and a slidable partition board (with water-absorbing cotton) are provided. In a humid or rainy environment, rainwater and water vapor can be effectively prevented from invading the interior of the box body through the heat dissipation holes. When the external environment is humid, the partition board descends and closely adheres to and blocks the opening of the guide cover, and the water-absorbing cotton further absorbs a small amount of moisture that may penetrate in, thus greatly reducing the threat of water vapor to the internal electrical modules.

[0008] Optionally, the control component includes a reset member for driving the connecting rod to slide downward and reset, and a driving member for driving the connecting rod to slide upward and reset; the driving member includes a push rod slidably provided on the upper side surface of the substrate, an electric cylinder fixedly provided on the substrate, and a battery for supplying energy to the electric cylinder. The electric cylinder is used to drive the push rod to slide reciprocally. A guiding inclined surface is provided on the lower edge of the connecting rod, and the push rod can slide along the guiding inclined surface and squeeze the connecting rod to slide upward.

[0009] By adopting the above technical solution, when controlling the partition board to slide up and down, the electric cylinder is used to drive the push rod to slide, and the guiding inclined surface is used to squeeze the connecting rod to rise, realizing the rapid blocking and opening of the partition board. This design not only improves the convenience and response speed of operation, but also enhances the reliability and stability of the device. At the same time, the structure is compact and occupies little space, which is beneficial to the overall layout of the grid-connected box. In addition, by adjusting the stroke and speed of the electric cylinder, it can flexibly adapt to different working environments and requirements.

[0010] Optionally, the reset member includes a spring, a baffle fixedly provided on the outer periphery of the connecting rod, and a guiding block fixedly provided on the inner wall of the box body. A guiding hole for the connecting rod to penetrate is provided on the guiding block, the guiding block is located above the baffle, and both ends of the spring are fixedly connected to the side surfaces of the guiding block and the baffle close to each other.

[0011] By adopting the above technical solution, the reset member realizes the automatic reset function of the connecting rod (and the partition plate) sliding downward through the combination of a spring, a baffle plate and a guide block. When the driving member releases the extrusion of the connecting rod, the elastic force of the spring pushes the baffle plate and the connecting rod to slide smoothly along the guide hole until they are closely attached and block the guide cover. This design not only improves the automation degree of the equipment, but also enhances the stability and reliability of the structure. At the same time, the setting of the guide block and the guide hole ensures the smoothness and accuracy of the sliding of the connecting rod, which is beneficial to extending the service life of the equipment.

[0012] Optionally, a plurality of support rods are hinged on the opposite vertical sides of the substrate, a roller is fixedly arranged at one end of the support rod, and an adjusting member for controlling the rotation adjustment of the support rod is arranged on the push rod; the roller can rotate with the support rod to a state protruding from the bottom side of the substrate, and can also rotate to a state flush with the bottom side of the substrate.

[0013] By adopting the above technical solution, the substrate realizes the flexible placement and stable support of the grid-connected box on different terrains through the design of hinged support rods and rollers. The adjusting member can control the rotation of the support rod, so that the roller protrudes from the bottom side of the substrate for easy movement, or rotates to be flush with the substrate to maintain stability. This design not only improves the portability and adaptability of the grid-connected box, but also facilitates rapid deployment and adjustment in complex environments. At the same time, the design of the roller reduces friction and resistance, which is beneficial to reducing energy consumption and wear during the movement process and extending the service life of the equipment.

[0014] Optionally, the adjusting member includes an adjusting rod fixedly arranged on the outer periphery of the push rod, a limiting rod is vertically fixedly arranged at the end of the support rod far away from the roller, a limiting convex block is fixedly arranged at the end of the limiting rod far away from the support rod, and a limiting notch is opened on the limiting convex block; the adjusting rod can slide synchronously with the push rod, and during this process, it squeezes the limiting rod and makes the support rod rotate until the end of the adjusting rod is stuck into the limiting notch, and the roller is in a state protruding from the bottom side of the substrate at this time.

[0015] By adopting the above technical solution, the adjusting member realizes the precise control of the rotation of the support rod during the sliding of the push rod through the cooperation of the adjusting rod with the limiting rod and the limiting convex block. When the push rod slides, the adjusting rod squeezes the limiting rod to make the support rod rotate until the end of the adjusting rod is stuck into the limiting notch. At this time, the roller protrudes from the bottom side of the substrate, which is convenient for the movement of the grid-connected box. This design not only improves the convenience and accuracy of the operation, but also enhances the stability and reliability of the structure.

[0016] Optionally, an elastic clamping member is arranged on the outer periphery of the adjusting rod, and a positioning groove for the elastic clamping member to be clamped into is opened on the inner wall of the limiting notch.

[0017] By adopting the above technical solution, the elastic clamping member on the adjusting rod cooperates with the positioning groove on the inner wall of the limiting notch, realizing the stable clamping between the adjusting rod and the limiting convex block. This design not only enhances the stability of the adjusting rod after being inserted into the limiting notch, preventing accidental detachment due to external forces, but also improves the safety and reliability of the grid-connected box during movement.

[0018] Optionally, a guiding inclined surface is provided on the opening edge of the limiting notch.

[0019] By adopting the above technical solution, the design of the guiding inclined surface enables the adjusting rod to slide into the limiting notch more smoothly, reducing the resistance and friction during the clamping process, which is beneficial to reducing the operation difficulty and improving the work efficiency.

[0020] Optionally, a reinforcing rod is fixedly provided on the bottom side of the box body above the support rod, and the outer side surface of the limiting convex block is an arc surface; when the roller rotates to a state flush with the bottom side of the substrate, the bottom side surface of the support rod in this state is flush with the bottom side of the substrate, and the lower end of the reinforcing rod abuts against the outer side surface of the limiting convex block at this time.

[0021] By adopting the above technical solution, when the roller rotates to be flush with the bottom side of the substrate, it provides additional support and limitation for the support rod. This design not only enhances the stability of the grid-connected box in the stationary state, preventing shaking or tilting due to external forces, but also improves the strength and durability of the structure. At the same time, the arc surface design makes the abutting process smoother, reducing friction and wear, which is beneficial to extending the service life of the equipment.

[0022] Optionally, an elastic pad is fixedly provided on the outer side surface of the limiting convex block.

[0023] By adopting the above technical solution, the elastic pad can increase the contact area between the limiting convex block and the reinforcing rod, improve the friction force between the two, thereby ensuring that the support rod is more stable in the stationary state and not prone to shaking or tilting. At the same time, the elastic pad can also play a buffering role, reducing the direct collision and friction between the limiting convex block and the reinforcing rod, and extending the service life of the equipment.

[0024] Optionally, a protective cover with a downward opening is fixedly provided on the outer edge of the heat dissipation port on the box body.

[0025] By adopting the above technical solution, the protective cover can effectively block external impurities such as dust and water droplets from entering the inside of the heat dissipation port, keeping the heat dissipation channel clean and unobstructed, thereby ensuring the normal heat dissipation of the electrical components inside the grid-connected box and preventing failures or damages caused by overheating. At the same time, the downward opening design can also guide liquids such as rainwater to flow down along the outer wall of the protective cover, avoiding it directly dripping into the heat dissipation port, further improving the waterproof performance of the grid-connected box.

[0026] In summary, the present application includes the following beneficial technical effects: In a humid or rainy environment, by providing a guide cover with an upward opening and a partition board (with absorbent cotton) that can slide up and down, rainwater and water vapor can be effectively prevented from invading the interior of the box through the heat dissipation holes. When the external environment is humid, the partition board descends and closely fits and seals the opening of the guide cover, and the absorbent cotton further absorbs a small amount of moisture that may penetrate, thus greatly reducing the threat of water vapor to the internal electrical modules.

[0032] Referring to Figure 3 and Figure 4 , a protection component 4 is provided inside the box body 1. The protection component 4 includes a blocking plate 41 slidably arranged on the inner wall of the box body 1 and located above the guiding cover 14. A plurality of blocking holes 411 are opened on the blocking plate 41, and these holes allow a certain amount of air to flow through. At the same time, a water-absorbing cotton 42 is fixedly provided on the blocking plate 41 to block and absorb a small amount of moisture that may enter through the blocking holes 411. Connecting rods 43 that penetrate through the bottom of the box body 1 and extend to the outside of the box body 1 are fixedly provided at both ends of the blocking plate 41. A control component 5 for driving the connecting rods 43 to slide up and down is provided on the base plate 3. When the blocking plate 41 slides up and down synchronously with the connecting rods 43, the opening of the guiding cover 14 can be blocked.

[0033] Reference Figure 3 and Figure 4 The control assembly 5 includes a reset member 51 for driving the connecting rod 43 to slide downward and reset, and a driving member 52 for driving the connecting rod 43 to slide upward and reset; the reset member 51 includes a spring 511 in a compressed state, a baffle 512 fixed on the outer periphery of the connecting rod 43, and a guide block 513 fixed on the inner wall of the box body 1, wherein the guide block 513 is provided with a guide hole 5131 for the connecting rod 43 to pass through, the guide block 513 is located above the baffle 512, and the two ends of the spring 511 are respectively fixedly connected to the side surfaces of the guide block 513 and the baffle 512 close to each other; The driving member 52 includes a push rod 521 slidably mounted on the upper side of the base plate 3, an electric cylinder 522 fixedly mounted on the base plate 3, and a battery 523 for supplying energy to the electric cylinder 522.

The push rod 521 can slide along the guide slope 431 and squeeze the connecting rod 43 to slide upward. In other embodiments, a protective shell (not shown in the figure) for external protection of the electric cylinder 522 and the battery 523 is fixedly mounted on the base plate 3 by screws to strengthen the protection of the electric cylinder 522 and the battery 523, which will not be described in detail here. When the outside is dry, if it is necessary to release the blockage of the guide cover 14 to restore heat dissipation, the electric cylinder 522 in the control assembly 5 will start and drive the push rod 521 to slide along the guide slope 431, squeezing the connecting rod 43 to slide upward, thereby releasing the blockage of the baffle plate 41 and the absorbent cotton 42 on the guide cover 14; When the outside is humid or rainy, if it is necessary to block the opening of the guide cover 14, the electric cylinder 522 is reset first, and then the reset member 51 in the control assembly 5 will automatically function to reset the connecting rod 43 and the blocking plate 41 downward and tightly fit and block the guide cover 14.

[0034] Reference Figure 5 and Figure 6 Two mutually symmetrical support rods 32 are hinged on the opposite vertical side surfaces of the base plate 3, wherein a roller 36 is fixedly arranged at one end of the support rod 32, and an adjusting member 6 for controlling the rotation and adjustment of the support rod 32 is arranged on the push rod 521; the adjusting member 6 comprises an adjusting rod 61 fixedly arranged on the outer periphery of the push rod 521, wherein a limiting rod 33 is vertically fixedly arranged on the end of the support rod 32 away from the roller 36, and a limiting protrusion 34 is integrally formed on the end of the limiting rod 33 away from the support rod 32, and a limiting notch 341 is provided on the limiting protrusion 34; When the grid connection box needs to be moved a short distance, first apply force to lift the whole grid connection box upward by a certain distance, and then start the electric cylinder 522 to make the push rod 521 and the adjusting rod 61 fixed thereon slide synchronously. During the sliding process of the adjusting rod 61, the limiting rod 33 is squeezed, so that the supporting rod 32 rotates around the hinge point until the end of the adjusting rod 61 is stuck in the limiting notch 341 on the limiting convex block 34. At this time, the roller 36 protrudes from the bottom side of the base plate 3, facilitating the movement of the grid connection box.

[0035] When the grid connection box moves to the designated position and is ready for installation, run the electric cylinder 522 in reverse to make the adjusting rod 61 disengage from the limiting notch 341 and release the locking of the supporting rod 32; then the user manually rotates the supporting rod 32 back to its position, making the roller 36 flush with the bottom side of the base plate 3, and at the same time the bottom side of the supporting rod 32 is also flush with the bottom side of the base plate 3 to ensure the stability of the grid connection box.

The elastic clamping member 62 includes a compression spring 621 and an arc-shaped convex block 622. A placement groove 611 for placing the compression spring 621 and the arc-shaped convex block 622 is opened on the outer periphery of the end of the adjusting rod 61. The compression spring 621 squeezes one side of the arc-shaped convex block 622, so that a part of the arc-shaped convex block 622 protrudes from the opening of the placement groove 611, and the outer side surface of the protruding part is an arc surface, and the arc length corresponding to the arc surface is a minor arc; A guiding inclined surface 3411 is provided on the opening edge of the limiting notch 341, and a positioning groove 3412 for the elastic clamping member 62 to be clamped into is opened on the inner wall of the limiting notch 341; it is convenient for the end of the adjusting rod 61 to be inserted into the limiting notch 341 along the guiding inclined surface 3411 until the elastic clamping member 62 is clamped into the corresponding positioning groove 3412.

[0037] Refer to Figure 5 As shown in [relevant figure number], a reinforcing rod 15 is fixedly arranged on the bottom side surface of the box body 1 above the supporting rod 32. The outer side surface of the limiting convex block 34 is an arc surface, and an elastic pad 35 made of rubber is fixed on the outer side surface of the limiting convex block 34 by glue; When the roller 36 rotates to a state flush with the bottom side of the base plate 3, the lower end of the reinforcing rod 15 abuts against the elastic pad 35, and one side of the push rod 521 abuts against one side of the limiting rod 33. This design not only improves the support stability of the base plate 3 for the box body 1, but also can reduce vibration and noise to a certain extent and improve the overall performance of the grid connection box.

[0038] The implementation principle of the embodiment of this application is: When it is humid, the sliding baffle 41 and the absorbent cotton 42 are used to block the guiding cover 14, and when it is dry, the electric cylinder 522 is driven to release the blockage to restore heat dissipation; the moving and fixing of the grid connection box are realized through the support rod 32, the roller 36 and the adjusting member 6; the elastic clamping member 62 on the adjusting rod 61 is convenient for clamping into the positioning groove 3412 of the limiting convex block 34 to lock the support rod 32; the design of the reinforcing rod 15 and the elastic pad 35 improves the support stability of the box body 1 and reduces vibration and noise.
