Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to a high-protection distribution box. Background Art

[0002] Distribution boxes, also known as distribution cabinets, serve as integrated units within motor control centers and play a crucial role in power systems. Their compact size, ease of installation, unique technical features, fixed location, specialized functional configuration, strong environmental adaptability, wide applicability, stable and reliable operation, efficient space utilization, small footprint, and significant environmental benefits make them the preferred equipment for power distribution and management.

[0003] Traditionally, a typical distribution box design consists of a main body and two doors. These doors are hinged to the main body at one edge, facing away from the other. The other edge is removably secured to the main body with a conventional lock. To ensure effective heat dissipation from the electrical components within the distribution box, designers typically carefully arrange multiple cooling vents on the side walls to promote air circulation and reduce internal temperatures.

[0004] However, when these distribution boxes are deployed outdoors, a significant concern arises: insects can exploit these heat dissipation vents as a gateway to infiltrate the box. This can not only disrupt the normal operation of the electrical equipment within, reducing its efficiency, but can also cause safety hazards such as short circuits and faults, threatening the stable operation of the power system. This presents room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a highly protected distribution box to solve the problem that when the above-mentioned distribution box is used outdoors, external insects may enter the box through the heat dissipation port, affecting the performance of the electrical equipment inside the box.

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

[0007] A high-protection distribution box comprises a box body and two box doors, wherein a partition plate is fixedly provided in the middle part of the box body in the vertical direction, one side of the box door is hinged to the box body, and the other side of the box body is detachably connected to the partition plate, and a plurality of heat dissipation holes are provided on the vertical side wall of the box body away from the partition plate; a blocking plate for blocking the heat dissipation holes is fixedly provided on the inner side surface of the box body, and a blocking hole coinciding with the heat dissipation hole is provided on the blocking plate, and a limiting groove is provided on the side of the blocking plate close to the heat dissipation hole, and a blocking net located in the limiting groove is fixedly provided on the inner wall of the box body.

[0008] By adopting the above technical solution, after the barrier plate is installed, due to the installation of the barrier net on the inner wall of the box, the barrier net is simultaneously located inside the limiting sink, further limiting the installation of the barrier net; the barrier net is used to reduce the possibility of external insects entering the box through the heat dissipation holes, thereby improving the performance of the electrical equipment in the box.

[0009] Optionally, an upper protective cover with an upward opening is fixedly provided on the side of the blocking plate away from the box body at the opening edge of the blocking hole, and a lower protective cover with a downward opening is fixedly provided on the outer opening edge of the heat dissipation hole of the box body.

[0010] By adopting the above technical solution, during the application of the distribution box, due to the coordinated setting of the upper protective cover and the lower protective cover, the opening size of the heat dissipation holes and the barrier holes can be reduced, further reducing the possibility of external insects entering, and also reducing the possibility of external rainwater entering the box through the heat dissipation holes and the barrier holes.

[0011] Optionally, a plurality of support cross bars for mounting electrical equipment are provided inside the box body, positioning blocks are fixed at both ends of the support cross bars, and positioning slots for the positioning blocks to be embedded and fixed are provided on the side walls of the box body away from the door.

[0012] By adopting the above technical solution, during the installation of the supporting cross bar, due to the matching setting of the positioning block and the positioning slot, the positioning block on the supporting cross bar can be embedded into the positioning slot on the inner wall of the box, thereby improving the installation efficiency of the supporting cross bar; and the electrical equipment inside the box can be installed on the supporting cross bar, thereby improving the space utilization inside the box.

[0013] Optionally, an elastic clamping piece is provided on the side surface of the positioning plug-in block, and a positioning groove for the elastic clamping piece to be clamped into is formed on the inner wall of the positioning slot.

[0014] By adopting the above technical solution, when the positioning block is inserted into the positioning slot, the elastic clip and the positioning groove are matched so that the elastic clip can be snapped into the positioning groove, thereby improving the installation stability of the positioning block in the positioning slot.

[0015] Optionally, a locking rod is provided on the inner wall of the box body for sliding in the vertical direction, and a control member is provided inside the box body for driving the locking rod to slide up and down in the vertical direction; a locking block is fixedly provided on the side of the locking rod and located below the supporting cross bar, a limiting plug is fixedly provided on the upper side of the locking block, and a limiting slot is provided on the supporting cross bar for inserting the limiting plug.

[0016] By adopting the above technical solution, due to the combined setting of the locking rod and the control member, when the control member drives the locking rod to slide upward, it also drives the locking block and the limit plug block to move upward, so that the limit plug block is inserted into the limit slot on the supporting cross bar, thereby improving the installation stability of the supporting cross bar.

[0017] Optionally, the control member is a control rod with one end hinged to the partition plate, the rotating surface of the control rod is parallel to the bottom side surface of the box body, and a guide bevel is fixed on the edge of the lower end of the locking rod; the control rod can rotate along the guide bevel to a state of abutting against the lower end of the locking rod, thereby allowing the limit plug to be inserted into the limit slot.

[0018] By adopting the above technical solution, during the use of the control part, the staff can rotate the control rod along the guide slope to a state of abutment with the lower end of the locking rod, so that the limit plug is inserted into the limit slot, thereby driving the locking rod to slide upward in the vertical direction, further locking the supporting cross bar.

[0019] Optionally, the lower part of the blocking plate is rotatably connected to the inner wall of the box, and the upper part of the blocking plate is detachably connected to the inner wall of the box; when the control rod is rotated to a state perpendicular to the side of the partition plate, the blocking plate can be rotated downward to a horizontal state and abut against the upper side of the control rod.

[0020] By adopting the above technical solution, when the inside of the distribution box needs to be inspected and the lock of the supporting cross bar is released, the blocking plate is rotated downward to a horizontal state due to the hinged setting of the blocking plate. In this state, the control rod supports the lower side of the blocking plate, and the opening of the limiting groove is facing upward. The removed screws can be placed inside the limiting groove on the blocking plate, reducing the possibility of losing the screws that are subsequently removed.

[0021] Optionally, a limiting notch is provided on the side of the blocking plate facing the control rod, and the upper edge of the control rod can be inserted into the limiting notch when the blocking plate rotates downward.

[0022] By adopting the above technical solution, due to the setting of the limiting notch, when the blocking plate is rotated downward to a horizontal state, the upper edge of the control rod can be inserted into the limiting notch on the bottom side of the blocking plate, thereby improving the supporting stability of the control rod on the blocking plate.

[0023] Optionally, a guide block is fixedly provided on the inner wall of the box body, and a guide through hole is opened on the guide block for the locking rod to pass through. A limiting protrusion located above the guide block is fixedly provided on the outer periphery of the locking rod, and the lower side surface of the limiting protrusion can abut against the upper side surface of the guide block.

[0024] By adopting the above technical solution, due to the combined setting of the guide block and the limiting protrusion, the sliding limitation of the locking rod is achieved, thereby enhancing the stability of the locking rod during the sliding process; the downward sliding stroke of the locking rod is also limited, thereby preventing the locking rod from sliding excessively downward.

[0025] Optionally, a receiving block located below the guide block is fixedly provided on the outer periphery of the locking rod, and a compression spring in a compressed state is provided inside the box body, and the two ends of the compression spring are respectively fixedly connected to the upper side of the receiving block and the lower side of the guide block, and the compression spring can squeeze the receiving block to make the limiting plug fall out of the limiting slot.

[0026] By adopting the above technical solution, after the control rod is rotated out from under the locking rod, due to the combination of the receiving block and the compression spring, the compression spring squeezes the receiving block, driving the locking rod and the limit plug to move downward as a whole, so that the limit plug can automatically disengage from the limit slot, facilitating the subsequent disassembly of the supporting cross bar.

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

[0028] 1. Due to the installation of the barrier net on the inner wall of the box, after the barrier plate is installed, the barrier net is simultaneously located inside the limiting sink, further limiting the installation of the barrier net; the barrier net can reduce the possibility of external insects entering the box through the heat dissipation holes, thereby improving the performance of the electrical equipment in the box.

DETAILED DESCRIPTION

[0040] The present application is further described in detail below in conjunction with all the accompanying drawings. Example

[0041] Reference Figure 1 、 Figure 2 and Figure 3 A high-protection distribution box includes a box body 1 and two box doors 2, wherein a partition plate 11 is fixedly provided in the middle part of the box body 1 in the vertical direction, one side of the box door 2 is hinged to the box body 1, and the other side edge of the box body 1 is detachably connected to the partition plate 11 through a conventional lock structure (not shown in the figure). The distribution box has a double-door structure; a plurality of heat dissipation holes 12 are evenly opened on the vertical side wall of the box body 1 away from the partition plate 11.

A blocking hole 31 is opened on the blocking plate 3 and coincides with the heat dissipation hole 12. A limited position sinking groove 32 is opened on the side of the blocking plate 3 close to the heat dissipation hole 12. A blocking net 4 is fixed on the inner wall of the box body 1 by screws;

[0043] The barrier net 4 is used to prevent external insects from entering the interior of the box 1 through the heat dissipation holes 12; after the barrier plate 3 is installed, the barrier net 4 is simultaneously located inside the limiting sink 32, further limiting the installation of the barrier net 4 and enhancing the installation stability of the barrier net 4.

[0046] During the application of the distribution box, a combination of the upper protective cover 33 and the lower protective cover 13 is used to reduce the opening size of the heat dissipation hole 12 and the barrier hole 31, thereby reducing the possibility of external insects and rainwater entering the interior of the box body 1; and the installation of the barrier net 4 can further prevent external insects from entering the interior of the box body 1 through the heat dissipation hole 12. Example

[0047] Reference Figure 5 、 Figure 6 and Figure 7 The embodiment of the present application differs from the embodiment 1 in that four support cross bars 5 for fixing the electrical equipment by clamping (or fixing with screws) are provided inside the box body 1. Positioning blocks 51 are fixed at both ends of the support cross bars 5. Positioning slots 14 for the positioning blocks 51 to be inserted and fixed are provided on the side wall of the box body 1 away from the box door 2. Elastic clamping members 52 are provided on the side surfaces of the positioning blocks 51, and positioning grooves 141 are provided on the inner walls of the positioning slots 14.

[0048] When the support cross bar 5 is installed, the positioning block 51 is inserted into the corresponding positioning slot 14, and at the same time, the elastic clip 52 on the positioning block 51 is snapped into the corresponding positioning groove 141, thereby improving the installation stability of the positioning block 51 in the positioning slot 14; after the support cross bar 5 is installed, the corresponding electrical equipment can be installed on the support cross bar 5, thereby improving the corresponding space utilization.

[0049] Reference Figure 6 and Figure 7The elastic clamping member 52 includes a spring 521 and an arc-shaped protrusion 522. The positioning plug 51 is provided with a placement groove 511 for the spring 521 and the arc-shaped protrusion 522 to be placed. The spring 521 squeezes the arc-shaped protrusion 522 so that a part of the arc-shaped protrusion 522 protrudes from the opening of the placement groove 511, and the outer side surface of the protruding part is an arc surface; when the positioning plug 51 is inserted into the positioning slot 14, the spring 521 squeezes the arc-shaped protrusion 522 so that a part of the arc-shaped protrusion 522 can be snapped into the positioning groove 141.

[0050] Reference Figure 6 and Figure 8 A locking rod 6 is provided on the inner wall of the box body 1 for sliding in the vertical direction, wherein a control member 7 is provided inside the box body 1 for driving the locking rod 6 to slide up and down in the vertical direction; a locking block 61 is fixedly provided on the side of the locking rod 6 and is located below the supporting cross bar 5, and a limiting plug 62 is fixedly provided on the upper side of the locking block 61, and a limiting slot 53 for inserting the limiting plug 62 is provided on the supporting cross bar 5; when the control member 7 drives the locking rod 6 to slide upward, the locking block 61 and the limiting plug 62 are driven to move upward, and then the limiting plug 62 is inserted into the limiting slot 53 on the supporting cross bar 5.

[0051] Reference Figure 8 The control member 7 is a control rod 71 hinged at one end to the partition plate 11, wherein the rotating surface of the control rod 71 is parallel to the bottom side of the box body 1, and a guide inclined surface 66 is fixed on the edge of the lower end of the locking rod 6; the control rod 71 can be rotated along the guide inclined surface 66 until it abuts against the lower end of the locking rod 6, thereby inserting the limit plug 62 into the limit slot 53, thereby driving the locking rod 6 to slide upward in the vertical direction.

[0052] Reference Figure 8 A guide block 15 is fixed to the inner wall of the box body 1 by screws, wherein a guide through hole 151 is opened on the guide block 15 for the locking rod 6 to pass through, and a limiting protrusion 63 is fixed on the outer periphery of the locking rod 6 and located above the guide block 15. The lower side of the limiting protrusion 63 can abut against the upper side of the guide block 15; firstly, the guide block 15 can limit the up and down sliding of the locking rod 6, and secondly, the setting of the limiting protrusion 63 can limit the downward sliding stroke of the locking rod 6.

[0053] Reference Figure 8 A receiving block 64 is fixedly provided on the outer periphery of the locking rod 6 and is located below the guide block 15. A compression spring 65 is provided inside the box body 1 in a compressed state, and the two ends of the compression spring 65 are respectively fixedly connected to the upper side of the receiving block 64 and the lower side of the guide block 15; when the control rod 71 is rotated out from the bottom of the locking rod 6, the compression spring 65 squeezes the receiving block 64, driving the locking rod 6 and the limiting plug 62 to move downward as a whole, thereby causing the limiting plug 62 to disengage from the limiting slot 53.

[0054] Reference Figure 8 and Figure 9 The lower part of the blocking plate 3 is rotatably connected to the inner wall of the box body 1, wherein the upper part of the blocking plate 3 is detachably connected to the inner wall of the box body 1 by a butterfly bolt, and a limiting notch 34 is provided on the side of the blocking plate 3 facing the control rod 71;

[0055] When it is necessary to inspect the inside of the distribution box, first rotate the control rod 71 to a position perpendicular to the side of the partition plate 11, then rotate the blocking plate 3 downward to a horizontal position, and the upper edge of the control rod 71 can be inserted into the limiting notch 34 on the bottom side of the blocking plate 3, so that the control rod 71 supports the lower side of the blocking plate 3.

[0056] The implementation principle of the embodiment of this application is:

[0057] When the distribution box is in normal use, the installation stability of the support cross bar 5 is enhanced due to the coordinated arrangement of the control rod 71 and the locking rod 6; when the electrical equipment installed on the support cross bar 5 in the distribution box needs to be repaired, the control rod 71 is rotated to a state perpendicular to the side of the partition plate 11, and then the blocking plate 3 is rotated downward to a horizontal state. At this time, the lock on the support cross bar 5 is released, and the removed screws can be placed inside the limiting groove 32 on the blocking plate 3, reducing the possibility of the screws being lost later.
