Description

Technical Field

[0001] This application relates to the technical field of distribution boxes, and in particular to a comprehensive distribution box. Background Technology

[0002] With the acceleration of social development and industrialization, electricity demand continues to rise, and the scale and complexity of power grid construction are constantly expanding. Against this backdrop, power distribution equipment, as a key component ensuring the stable operation of the power system, faces higher demands. Integrated distribution boxes, as electrical devices integrating power distribution, control, and protection functions, have emerged, offering significant advantages in integrated and modular design, and flexibly adapting to power distribution needs in different scenarios. Thanks to their excellent performance, integrated distribution boxes are widely used in various fields such as industrial production, commercial operations, and residential power supply, becoming an important tool for ensuring reliable power supply and improving system management efficiency.

[0003] In related technologies, an integrated distribution box for outdoor environments includes a box body, wherein a door is installed on the vertical side of the box body, one vertical edge of the door is rotatably connected to the box body, and the other vertical edge of the door is detachably connected to the box body through a conventional locking structure; at the same time, in order to ensure heat dissipation of electrical equipment inside the box, several heat dissipation vents are opened on the vertical inner wall of the box body, and the heat generated by the operation of the equipment is removed through air circulation, so as to maintain a suitable operating temperature inside the box and ensure the normal operation of electrical equipment.

[0004] However, in outdoor environments where such integrated distribution boxes are used, rainwater can easily enter the box through the ventilation vents during frequent rain. This intrusion causes a sharp increase in humidity inside the box, potentially leading to decreased insulation performance of electrical equipment, short circuits, and other malfunctions. This severely impacts the performance and lifespan of the electrical equipment and could even cause a complete power system outage, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an integrated distribution box that solves the problem in the aforementioned related technologies where external rainwater easily enters the box through the heat dissipation vents, affecting the performance of the internal electrical equipment.

[0006] The integrated distribution box provided in this application adopts the following technical solution:

[0007] A comprehensive distribution box includes a box body, an installation cavity and a door for sealing the opening of the installation cavity are provided on the vertical side of the box body, and a plurality of heat dissipation vents are provided on the two opposite vertical sides of the box body; an upward-opening guide shroud is fixed on the inner wall of the heat dissipation vents of the box body, and a protective plate is installed on the inner wall of the box body along the vertical direction on the side of the guide shroud away from the heat dissipation vents.

[0008] By adopting the above technical solution, an upward-opening guide shroud is installed on the inner wall of the heat dissipation vent. When rainwater falls, the guide shroud can block and guide the rainwater, allowing it to flow away along the shroud and preventing it from directly entering the enclosure. This reduces the humidity inside the enclosure and decreases the risk of electrical equipment insulation degradation, short circuits, and other malfunctions caused by excessive humidity, ensuring the normal operation of the electrical equipment and extending its service life. Simultaneously, a protective plate is installed on the side of the guide shroud away from the heat dissipation vent. This not only provides space for the guide shroud to ensure proper heat dissipation but also provides some protection for the inner wall of the enclosure and the guide shroud, preventing accidental collisions with internal components. This further ensures the safety and stability of the electrical equipment inside the enclosure and improves the overall reliability and practicality of the integrated distribution box.

[0009] Optionally, the protective plate is provided with a number of positioning protrusions that can abut against the inner wall of the box on the side edge facing the air guide shroud; the protective plate is provided with a number of fixing through holes, the inner wall of the box is provided with fixing screw holes that can coincide with the fixing through holes, and the box is provided with fixing bolts that pass through the fixing through holes and are screwed into the fixing screw holes.

[0010] By adopting the above technical solution, the positioning protrusions enable quick and accurate positioning of the protective plate during installation, improving installation efficiency and accuracy. The fixing bolts penetrate the fixing through-holes in the protective plate and screw into the fixing screw holes on the inner wall of the box, ensuring a stable installation and guaranteeing the protective plate's consistent protective function. Furthermore, this detachable fixing method facilitates subsequent maintenance and replacement of the protective plate, reducing maintenance difficulty and costs, and contributing to maintaining the overall stability of the integrated distribution box's performance.

[0011] Optionally, an extension plate is vertically fixed to the lower edge of the protective plate, and a locking plate is vertically fixed to the upper edge of the protective plate. The locking plate and the extension plate are arranged side by side and both face the inner wall of the box with the heat dissipation vent. The side of the extension plate away from the protective plate is rotatably connected to the inner wall of the box, and the side of the extension plate away from the locking plate abuts against the inner wall of the box when the protective plate is rotated to a horizontal state. The inside of the box is provided with a locking device to keep the protective plate in a vertically upward state.

[0012] By adopting the above technical solution, the extension plate is rotatably connected to the inner wall of the enclosure, allowing the protective plate to rotate to a horizontal position. At this point, the side of the extension plate abuts against the inner wall of the enclosure, providing a platform for placing maintenance tools and facilitating maintenance operations. Under normal conditions, the locking mechanism keeps the protective plate vertically upward, meeting normal protection requirements.

[0013] Optionally, the locking plate has a locking through hole, and the inner wall of the box has a locking screw hole that coincides with the locking through hole when the protective plate is in a vertical state. The locking component is a locking bolt that passes through the locking through hole and is screwed into the locking screw hole.

[0014] By adopting the above technical solution, a locking through hole is opened on the locking plate, and a corresponding locking screw hole is opened on the inner wall of the box. The locking bolt is screwed into the locking screw hole through the locking through hole to lock the protective plate. The structure is simple and the operation is convenient. This locking method is stable and reliable, ensuring that the protective plate remains stable in the vertical position, effectively playing a protective role, preventing the protective plate from shifting due to shaking or external force, ensuring the safety of the internal components of the integrated distribution box, and facilitating installation, disassembly and maintenance.

[0015] Optionally, a barrier plate can be detachably installed on both sides of the protective plate facing the extension plate. The barrier plate has several connecting holes. The length direction of the barrier plate is perpendicular to the length direction of the extension plate. The two ends of the barrier plate face the locking plate and the extension plate, respectively.

[0016] By adopting the above technical solution, a barrier plate can be detachably installed on the side of the protective plate, facilitating flexible installation and replacement according to actual needs. The barrier plate has connecting holes, which, without affecting gas flow and ensuring heat dissipation, can also seal the gap between the protective plate and the inner wall of the enclosure when the protective plate is in a specific state. This reduces the entry of external impurities into the enclosure, minimizing their impact on electrical equipment and improving the stability and safety of the integrated distribution box.

[0017] Optionally, the end of the barrier plate facing the extension plate is provided with a connector for connecting to the protective plate, and the locking plate is provided with a locking notch for the other end of the barrier plate to be inserted.

[0018] By adopting the above technical solution, the connector provides a flexible and stable way to connect the barrier plate and the protective plate, facilitating the installation of the barrier plate and allowing for subsequent disassembly or adjustment according to actual needs. The locking notch further enhances the stability of the barrier plate installation, enabling the barrier plate to be accurately positioned and firmly fixed, thereby effectively fulfilling its function of sealing gaps and preventing impurities from entering the enclosure, ensuring the normal operation and safety of the electrical equipment inside the integrated distribution box.

[0019] Optionally, the barrier plate is provided with an elastic snap-fit ​​component, and the inner wall of the locking notch is provided with a positioning groove for the elastic snap-fit ​​component to snap into.

[0020] By adopting the above technical solution, when the barrier plate is embedded in the locking notch, the elastic snap-fit ​​component can engage with the positioning groove, achieving a stable connection between the barrier plate and the locking notch. This snap-fit ​​method is not only convenient to install, requiring no complicated tools, but also effectively prevents the barrier plate from loosening or shifting, enhancing its installation reliability. Simultaneously, when disassembly is required, a certain amount of external force can be used to disengage the elastic snap-fit ​​component from the positioning groove, facilitating the maintenance and replacement of the barrier plate and improving the usability of the integrated distribution box.

[0021] Optionally, the connector includes a connecting block slidably disposed on the side of the protective plate facing the extension plate, and a connecting rod rotatably connected at one end to the connecting block. The connecting block can reciprocate along the length of the extension plate. The other end of the connecting rod is rotatably connected to the end face of the barrier plate facing the extension plate. The rotation surfaces of the connecting rod and the barrier plate are both perpendicular to the length of the extension plate. Several elastic scrapers are fixed on the side of the protective plate away from the protective plate. When the protective plate is in a horizontal state, the barrier plate can rotate towards the direction of the flow guide to a vertical state. When the barrier plate is in a vertical state, the elastic scrapers can be inserted into the opening of the flow guide. At this time, the elastic scrapers can clean the inner wall of the flow guide as the connecting block slides.

[0022] By adopting the above technical solution, when the protective plate is in a horizontal state, the baffle plate can be rotated to a vertical state. At this time, the elastic scraper on the side of the protective plate can be inserted into the opening of the guide shroud and slide along with the connecting block to clean the inner wall of the guide shroud. This effectively removes dust, debris, and other accumulated dust and debris from the guide shroud, ensuring the ventilation and heat dissipation effect of the guide shroud, thereby maintaining a good heat dissipation environment inside the integrated distribution box and reducing the risk of equipment failure due to poor heat dissipation. Moreover, this method of cleaning by rotating the baffle plate and sliding the connecting block does not require additional complicated cleaning tools and operating procedures. It can be easily completed in the daily maintenance of the equipment, reducing maintenance costs and difficulty, and improving the reliability and stability of the integrated distribution box operation.

[0023] Optionally, the end of the barrier plate facing the extension plate is ball-jointed with the end of the connecting rod away from the connecting block, and the protective plate has receiving grooves on its side facing the extension plate, the same number as the elastic scraper; the elastic scraper can rotate with the barrier plate to the side facing the protective plate, and the elastic scraper can be inserted into the receiving groove for storage after it is locked into the locking notch at one end of the barrier plate.

[0024] By adopting the above technical solution, when the elastic scraper rotates with the baffle plate to face the side of the protective plate, and one end of the baffle plate is engaged in the locking notch, the elastic scraper can be inserted into the receiving slot for storage. This design not only makes the overall structure more compact and saves space inside the box, but also prevents the elastic scraper from being damaged by accidental collisions when not in use, thus extending its service life. Furthermore, when cleaning the guide shield is required, simply rotating the baffle plate to the appropriate position allows the elastic scraper to function, making operation convenient and efficient. This design, which balances flexible installation, space utilization, and component protection, helps improve the overall performance and reliability of the integrated distribution box.

[0025] Optionally, the protective plate has a guide groove on the side facing the extension plate for the connecting block to be inserted and slid, and a limiting protrusion is fixed on the opposite two sides of the connecting block. The inner wall of the guide groove has a limiting groove for the limiting protrusion to be inserted and slid.

[0026] By adopting the above technical solution, a guide groove is opened on the side of the protective plate for the connecting block to be inserted and slid. At the same time, limiting protrusions are provided on both sides of the connecting block, and a limiting groove is provided on the inner wall of the guide groove to cooperate with it. This can play a precise guiding role in the sliding of the connecting block, prevent it from deviating during the sliding process, and ensure the stability of the moving trajectory of the connecting block.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When rain falls, the deflector can block and guide the rainwater, allowing it to flow away along the deflector and preventing it from directly entering the enclosure. This reduces the humidity inside the enclosure, thereby reducing the risk of electrical equipment insulation degradation, short circuits, and other malfunctions caused by excessive humidity. It ensures the normal operation of electrical equipment and extends its service life.

[0029] 2. Installing a protective plate on the side of the air guide shroud away from the heat dissipation vent not only provides space for the air guide shroud to ensure its normal airflow and heat dissipation, but also provides a certain degree of protection for the inner wall of the box and the air guide shroud, avoiding accidental collisions of internal components, further ensuring the safety and stability of the electrical equipment inside the box, and improving the overall reliability and practicality of the integrated distribution box.

[0042] The present application will be further described in detail below with reference to all the accompanying drawings.

[0043] Example 1:

[0044] Reference Figure 1 and Figure 2 A comprehensive distribution box includes a box body 1, wherein a mounting cavity 11 is provided on the vertical side of the box body 1 and a box door 2 for sealing the opening of the mounting cavity 11 is installed; one vertical edge of the box door 2 is rotatably connected to the vertical edge of the opening of the mounting cavity 11, and the other vertical edge of the box door 2 is detachably connected to the box body 1 through a conventional lock structure.

[0045] The box body 1 and the box door 2 can be injection molded using any of the following: PC+ABS, PC+ASA gold-containing plastic, or PP+LGF (long glass fiber reinforced polypropylene); or they can be molded using high-performance SMC composite materials or machined and welded using stainless steel materials.

[0046] Reference Figure 3The box body 1 has several heat dissipation vents 12 on its two opposite vertical sides. The box body 1 has an upward-facing guide shroud 13 fixed on the inner wall of the heat dissipation vents 12. The guide shroud 13 is processed by a stamping machine. After the heat dissipation vents 12 are stamped out, the guide shroud 13 is formed simultaneously. The inner wall of the box body 1 has a protective plate 3 installed in the vertical direction on the side of the guide shroud 13 away from the heat dissipation vents 12.

[0047] Reference Figure 2 and Figure 3 The protective plate 3 has several positioning protrusions 31 integrally formed on the side edge of the air guide shroud 13 that can abut against the inner wall of the box 1; the protective plate 3 has four fixing through holes, the inner wall of the box 1 has fixing screw holes that can coincide with the fixing through holes, and the box 1 has fixing bolts 4.

[0048] When installing the protective plate 3, the four fixing through holes are aligned with the fixing screw holes. Then, the fixing bolts 4 are screwed into the fixing screw holes after passing through the fixing through holes with a tool. After the protective plate 3 is installed, the positioning protrusion 31 abuts against the inner wall of the box 1, so that there is a gap between the protective plate 3 and the inner wall of the box 1 to allow the flow guide 13 to be placed.

[0049] The implementation principle of this application embodiment is as follows:

[0050] An upward-opening airflow guide shroud 13 is provided on the inner wall of the heat dissipation vent 12. It is formed simultaneously by a stamping machine, which not only facilitates heat dissipation inside the housing 1, but also effectively prevents rainwater, dust and other foreign objects from entering, protecting the internal components. The protective plate 3 is installed on the side of the airflow guide shroud 13 away from the heat dissipation vent 12. Its positioning protrusion 31 abuts against the inner wall of the housing 1, forming a clearance for the airflow guide shroud 13. This not only provides space for the airflow guide shroud 13 to ensure its normal airflow and heat dissipation, but also provides a certain degree of protection for the inner wall of the housing 1 and the airflow guide shroud 13, preventing accidental collisions with internal components.

[0051] Example 2:

[0052] Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that an extension plate 32 is vertically fixed on the lower edge of the protective plate 3, and a locking plate 33 is vertically fixed on the upper edge of the protective plate 3. The protective plate 3, the locking plate 33 and the extension plate 32 are integrally bent and formed, and the locking plate 33 and the extension plate 32 are arranged side by side and both face the inner wall of the box 1 where the heat dissipation vent 12 is opened.

[0053] The side of the extension plate 32 away from the protective plate 3 is rotatably connected to the inner wall of the box 1. The side of the extension plate 32 away from the locking plate 33 abuts against the inner wall of the box 1 when the protective plate 3 is rotated to a horizontal state. The box 1 is provided with a locking element 5 to keep the protective plate 3 in a vertically upward state.

[0054] When the electrical equipment inside the enclosure 1 is being repaired, it is convenient for the staff to place the repair tools on the upper side of the horizontal protective plate 3. Under normal conditions, the protective plate 3 can be kept vertical by using the locking piece 5. In this state, the side of the extension plate 32 and the locking plate 33 away from the protective plate 3 abuts against the inner wall of the enclosure 1, so that there is a gap between the protective plate 3 and the inner wall of the enclosure 1 to allow the guide shroud 13 to be placed.

[0055] Reference Figure 5 The locking plate 33 has a locking through hole, and the inner wall of the housing 1 has a locking screw hole that coincides with the locking through hole when the protective plate 3 is in a vertical state. The locking component 5 is a locking bolt 51 that passes through the locking through hole and is screwed into the locking screw hole. The locking bolt 51 is a wing bolt.

[0056] Reference Figure 5 and Figure 6 On the side of the protective plate 3 facing the extension plate 32, a barrier plate 6 can be detachably installed on both sides. The barrier plate 6 has several connecting holes 61 to facilitate gas flow. The length direction of the barrier plate 6 is perpendicular to the length direction of the extension plate 32, and the two ends of the barrier plate 6 face the locking plate 33 and the extension plate 32 respectively.

[0057] When the protective plate 3 is in a horizontal state, the protective plate 3, the extension plate 32, the locking plate 33 and the two barrier plates 6 together form a storage cavity with the tool inserted and the opening facing upward; when the protective plate 3 is in a vertically upward state, the two barrier plates 6 seal the vertical gap between the protective plate 3 and the inner wall of the box 1, reducing the possibility of external impurities entering the interior of the box 1 through this gap.

[0058] Reference Figure 6 and Figure 7 The barrier plate 6 is provided with a connector 7 at the end facing the extension plate 32, which is connected to the protective plate 3. The locking plate 33 is provided with a locking notch 331 for the other end of the barrier plate 6 to be inserted. When the barrier plate 6 is installed, one end of the barrier plate 6 is connected to the protective plate 3 through the connector 7, and the other end of the barrier plate 6 can be inserted into the locking notch 331, thereby realizing the installation and fixation of the barrier plate 6 and the protective plate 3.

[0059] Reference Figure 7 and Figure 8 The connecting component 7 includes a connecting block 71 slidably disposed on the side of the protective plate 3 facing the extension plate 32, and a connecting rod 72 rotatably connected to the connecting block 71 at one end. The connecting block 71 can slide back and forth along the length direction of the extension plate 32, and the other end of the connecting rod 72 is rotatably connected to the end face of the barrier plate 6 facing the extension plate 32. The rotation surfaces of the connecting rod 72 and the barrier plate 6 are both perpendicular to the length direction of the extension plate 32. Several elastic scrapers 63 are fixed on the side of the protective plate 3 away from the protective plate 3.

[0060] When the protective plate 3 is in a horizontal state, the barrier plate 6 can rotate towards the direction of the flow guide 13 to a vertical state. At this time, the elastic scraper 63 can be inserted into the opening of the flow guide 13. Then, when the connecting block 71 slides, it can drive the elastic scraper 63 to slide synchronously, so as to efficiently clean the impurities adhering to the inner wall of the flow guide 13.

[0061] Reference Figure 7 and Figure 8 The protective plate 3 has a guide groove 35 on the side facing the extension plate 32 for the connecting block 71 to be inserted and slid. The connecting block 71 has a limiting protrusion 711 integrally formed on both opposite sides, and a limiting groove 351 for the limiting protrusion 711 to be inserted and slid on the inner wall of the guide groove 35; thereby realizing the sliding connection between the connecting block 71 and the protective plate 3.

[0062] Reference Figure 7 and Figure 8 The end of the barrier plate 6 facing the extension plate 32 is ball-jointed with the end of the connecting rod 72 away from the connecting block 71, wherein the protective plate 3 has the same number of receiving grooves 34 as the elastic scraper 63 on its side facing the extension plate 32.

[0063] When it is not necessary to use the elastic scraper 63 to clean the inner wall of the flow guide shroud 13, the operator can rotate the elastic scraper 63 along with the baffle plate 6 to the side facing the protective plate 3, and then after the baffle plate 6 is engaged with the locking notch 331 at one end, the elastic scraper 63 can be inserted into the receiving groove 34 for storage.

[0064] Reference Figure 9 and Figure 10 The barrier plate 6 is provided with an elastic snap-fit ​​member 73, and the inner wall of the locking notch 331 is provided with a positioning groove 332 for the elastic snap-fit ​​member 73 to snap into. When the barrier plate 6 is snapped into the locking notch 331 with the end of the locking plate 33 facing it, the elastic snap-fit ​​member 73 snaps into the corresponding positioning groove 332, thereby improving the installation stability of the barrier plate 6 in the locking notch 331.

[0065] The elastic snap-fit ​​component 73 specifically includes a compression spring 731 and an arc-shaped protrusion 732. The barrier plate 6 has a placement groove 62 for the compression spring 731 and the arc-shaped protrusion 732 to be placed in. One end of the compression spring 731 presses against one side of the arc-shaped protrusion 732, causing a part of the arc-shaped protrusion 732 to protrude from the opening of the placement groove 62. The protruding part of the arc-shaped protrusion 732 is an arc surface, and the arc length corresponding to the arc surface is a minor arc.

[0066] The implementation principle of this application embodiment is as follows:

[0067] Maintenance tool placement status: When the electrical equipment inside the enclosure 1 is being maintained, the locking piece 5 is released from the locking of the protective plate 3, and the protective plate 3 is rotated to a horizontal position. The side of the extension plate 32 away from the locking plate 33 abuts against the inner wall of the enclosure 1. At this time, the protective plate 3, the extension plate 32, the locking plate 33 and the two barrier plates 6 form a storage cavity, on which maintenance tools can be placed.

[0068] Normal protection state: Under normal conditions, the protective plate 3 is locked in a vertical position with locking bolt 51. The extension plate 32 and locking plate 33 abut against the inner wall of the box 1 away from the protective plate 3, forming a clearance gap for the guide shroud 13. The two barrier plates 6 block the vertical gap to reduce the entry of external impurities.

[0069] Cleaning state of the flow guide 13: First, rotate the protective plate 3 to a horizontal position. During this process, rotate the baffle plate 6 towards the flow guide 13 to a vertical position so that the elastic scraper 63 is inserted into the opening of the flow guide 13. Then, slide the connecting block 71 to drive the elastic scraper 63 to slide and clean the impurities on the inner wall of the flow guide 13. After cleaning, rotate the elastic scraper 63 with the baffle plate 6 to face the side of the protective plate 3 and insert it into the receiving groove 34 for storage.
