Description

Technical Field

[0001] The present application relates to the technical field of distribution box processing, and in particular to an aluminum alloy structure distribution box. Background Art

[0002] A distribution box is a key device in a power system used to centrally house distribution equipment, distribute electrical energy, protect circuits, and control electrical devices. It serves as the dispatching center for the power network, safely and orderly distributing power from the grid to various power terminals.

[0003] In related art, a distribution box consists of a housing and components housed within it. The housing typically features heat dissipation vents, and a wire mesh is installed inside the housing at the vents. Both the housing and the mesh are made of stainless steel, and the mesh is welded to the stainless steel housing. The mesh reduces the possibility of debris entering the housing through the vents and affecting the normal operation of the components within. The mesh typically has large apertures to prevent debris from entering the housing without affecting the heat dissipation of the distribution box.

[0004] However, since the shell of the above-mentioned distribution box is made entirely of stainless steel, the overall weight of the distribution box is relatively large, which is inconvenient to install and transport, and thus needs to be improved. Summary of the Invention

[0005] In order to make the distribution box lighter, the present application provides an aluminum alloy structure distribution box.

[0006] The present application provides an aluminum alloy structure distribution box adopting the following technical solutions: An aluminum alloy structure distribution box includes a shell and components arranged in the shell. The shell is provided with a heat dissipation vent for heat dissipation. The inner wall of the shell is provided with a wire mesh at the heat dissipation vent. The wire mesh is made of stainless steel. The shell is made of aluminum alloy. The inner wall of the shell is provided with a connector at the edge of the heat dissipation vent. A pressure plate is provided on the inside of the shell. A receiving groove is provided on the pressure plate. A through hole connecting the heat dissipation vent and the interior of the shell is provided on the groove wall of the receiving groove. The wire mesh is provided in the receiving groove. The connector is used to detachably connect the pressure plate and the shell.

[0007] By adopting the above technical solution, the housing is made of aluminum alloy, which reduces its overall weight, making the distribution box easier to install or transport. Furthermore, the wire mesh is detachably connected to the housing via a pressure plate and connectors. This allows the mesh to be removed from the housing for cleaning or replacement if damaged or contaminated, facilitating mesh maintenance. Furthermore, the stainless steel wire mesh is physically isolated from the aluminum alloy housing, effectively reducing the possibility of electrochemical corrosion between the housing and the wire mesh when the distribution box is powered on, thereby extending the service life of the distribution box.

[0008] Optionally, the connecting piece is made of aluminum alloy material, and includes a connecting stud welded to the inner wall of the shell, and a connecting nut threadedly connected to the connecting stud, and the pressure plate is provided with a connecting hole for the connecting stud to pass through.

[0009] By adopting the above technical solution, when the pressure plate needs to be removed from the shell, it is only necessary to loosen the connecting nut first, and then move the pressure plate in the direction away from the connecting stud so that the connecting stud moves out of the connecting hole; when the pressure plate needs to be installed on the shell, it is only necessary to move the pressure plate in the direction close to the connecting stud so that the connecting stud extends into the connecting hole, and finally tighten the connecting nut on the connecting stud. After the installation is completed, the connecting nut is located on the side of the pressure plate away from the shell, so that the connecting nut can fix the pressure plate on the shell. The operation is simple, and it is convenient to disassemble and assemble the pressure plate and the wire mesh, while making the connection between the pressure plate and the shell highly stable. In addition, the connecting stud is made of the same aluminum alloy material as the shell, which is convenient for welding the connecting stud to the shell, and then it is convenient to fix the stainless steel wire mesh at the heat dissipation port.

[0010] Optionally, the pressing plate is made of stainless steel, and the wire mesh is connected to the groove wall of the accommodating groove by welding.

[0011] By adopting the above technical solution, it is convenient to fix the wire mesh on the pressure plate. When the wire mesh is installed at the heat dissipation outlet on the inner side of the shell, since the wire mesh is welded to the pressure plate, the connection strength between the wire mesh and the pressure plate is high, which makes it convenient to use the pressure plate to fix the wire mesh on the inner side of the shell, thereby ensuring the filtering effect of the wire mesh on impurities.

[0012] Optionally, two anti-slip grooves arranged opposite to each other are provided on the hole wall of the connecting hole, and a locking piece is provided on the pressure plate. The locking piece includes a stop block and a stop spring arranged in the anti-slip groove, and the stop block is slidably arranged in the anti-slip groove. The stop block is arranged on the side of the stop spring close to the connecting stud, and the stop spring is connected to the groove wall of the anti-slip groove. A limiting groove for the stop block to extend into is provided on the circumferential side wall of the connecting stud, and an unlocking piece for moving the stop block out of the limiting groove is provided on the pressure plate.

[0013] By adopting the above technical solution, when the pressure plate needs to be connected to the housing, the unlocking member can be operated first to move the two stop blocks away from each other, thereby moving the stop blocks out of the connection hole, so that the stop blocks are less likely to hinder the connecting stud from extending into the connection hole. Then, the pressure plate can be moved toward the connecting stud, so that the connecting stud extends into the connection hole, and the unlocking member can be released to allow the stop blocks to extend into the limiting groove. Through the above arrangement, even if the connecting nut becomes loose after long-term use, the groove wall of the limiting groove can still limit the stop blocks, making it difficult for the connecting stud to move out of the connection hole, thereby increasing the connection strength between the pressure plate and the housing and improving the anti-loosening effect of the pressure plate.

[0014] Optionally, a sliding groove is provided on a side wall of the pressure plate close to the connecting nut, and the sliding groove is connected to the anti-slip groove. The unlocking member includes a sliding block slidably arranged in the sliding groove, and the sliding block is provided with a sliding hole for passing the connecting stud. The sliding block is arranged between two stop blocks, and the sliding block extends out of the pressure plate. The width of the sliding block close to the wire mesh is greater than the width of the side away from the wire mesh.

[0015] By adopting the above technical solution, when the stop block needs to be moved out of the limiting groove, it is only necessary to first loosen the connecting nut and then slide the sliding block in a direction away from the wire mesh so that the two side walls of the sliding block respectively abut against the two stop blocks. In the process of sliding the sliding block away from the wire mesh, the side walls of the sliding block push the two stop blocks away from each other, thereby moving the stop block out of the limiting groove, so that the connecting stud can be moved out of the connecting hole, and the pressure plate can be removed from the housing. When the pressure plate needs to be installed on the housing, the sliding block can first be slid in a direction away from the wire mesh so that the stop block is moved out of the connecting hole, so that the connecting stud can be inserted into the connecting hole, and the pressure plate can be installed.

[0016] Optionally, a fixing part for fixing the wire mesh is provided in the accommodating groove, and the fixing part includes a fixing spring respectively arranged on the two groove walls of the accommodating groove close to the sliding block, and a fixing block arranged on different fixing springs, and a guide slope is provided on the fixing block, and the guide slope is inclined along the direction in which the wire mesh extends into the accommodating groove, and the expansion and contraction direction of the fixing spring is perpendicular to the direction in which the wire mesh extends into the accommodating groove, and a fixing groove is opened on the fixing block, and the wire mesh is arranged in the fixing groove.

[0017] By adopting the above technical solution, when the wire mesh needs to be fixed in the receiving groove, the two fixing blocks can be pushed away from each other first, and then the wire mesh is placed in the receiving groove so that the wire mesh is located on the side of the fixing blocks away from the shell. Then, the fixing blocks are released. At this time, the fixing blocks will move towards each other under the action of the fixing springs, so that the wire mesh extends into the fixing groove. The groove wall of the fixing groove can prevent the wire mesh from moving out of the receiving groove, thereby fixing the wire mesh with a good fixing effect. Through the above arrangement, when the wire mesh is damaged or accumulates dirt, the two fixing blocks can be pushed away from each other first, so that the wire mesh moves out of the fixing groove. The wire mesh can be taken out of the receiving groove and then cleaned or a new wire mesh can be installed in the receiving groove without replacing the pressure plate, which is beneficial to saving resources.

[0018] Optionally, a retraction rod is connected to one end of the fixed block close to the sliding block, an unlocking groove connected to the sliding groove is provided on the pressure plate, an unlocking plate is slidably arranged in the unlocking groove, the sliding direction of the unlocking plate is consistent with the sliding direction of the sliding block, the retraction rod is connected to the unlocking plate, and the unlocking plate is connected to the sliding block.

[0019] By adopting the above technical solution, when the two fixed blocks need to be pushed away from each other, it is only necessary to slide the sliding block away from the wire mesh. The sliding block will drive the unlocking plate to slide away from the wire mesh, and the unlocking plate will drive the retraction rod to slide away from the wire mesh, which in turn causes the retraction rod to drive the fixed block to move away from the wire mesh, causing the two fixed blocks to move away from each other. In this way, when installing or removing the pressure plate, it is also necessary to slide the sliding block away from the wire mesh, which can simultaneously drive the fixed blocks to move away from each other, without having to move the fixed blocks away from each other separately. This simplifies the structure of the pressure plate and the operation steps. It can also unlock the fixing parts and the locking parts at the same time, allowing the connecting studs to be removed from the connecting holes and the wire mesh to be removed from the receiving slots, thereby improving the efficiency of assembly and disassembly.

[0020] Optionally, the shell includes side panels, a bottom plate and a top plate, the heat dissipation port is opened on the side panel, a rainproof cover is provided on the outer wall of the heat dissipation port, the rainproof cover is arc-shaped and is open on the side close to the bottom plate, a plurality of support rods are provided on the side of the wire mesh away from the pressure plate, a cleaning plate is rotatably provided on the inner wall of the heat dissipation port close to the top plate, the cleaning plate is arc-shaped, and when the pressure plate is installed on the side panel, the support rod presses the cleaning plate against the rainproof cover, and the arc surface of the cleaning plate fits with the arc surface of the rainproof cover.

[0021] By adopting the above technical solution, when the heat dissipation vent is blocked by debris, the pressure plate can be removed from the side plate first to release the abutment effect of the support rod on the cleaning plate. Then, the cleaning plate will automatically rotate toward the inner side of the shell under the action of gravity, thereby cleaning the debris accumulated in the heat dissipation vent, making it easier to clean the debris in the heat dissipation vent, so that the heat dissipation vent remains unobstructed, which is beneficial to the heat dissipation of the distribution box, thereby ensuring the normal operation of the components in the distribution box.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The shell of the distribution box is made of aluminum alloy, which reduces the overall weight of the distribution box and facilitates transportation and installation of the distribution box. The pressure plate is connected to the shell through aluminum alloy connecting studs, which solves the problem of stainless steel wire mesh being difficult to weld to the aluminum alloy shell. 2. By setting a locking piece in the pressure plate, when the pressure plate is connected to the shell, the stop block can limit the connection stud, making it difficult for the pressure plate to separate from the shell, and having a good anti-loosening effect; 3. A cleaning plate is installed at the heat dissipation port to facilitate cleaning of debris in the heat dissipation port, which is beneficial to ensuring the heat dissipation effect of the distribution box.

[0031] The following is combined with Figure 1-7 This application is described in further detail.

[0032] The embodiment of the present application discloses an aluminum alloy structure distribution box.

[0033] Example 1 Reference Figure 1 and Figure 2 An aluminum alloy distribution box includes a housing 1 and components (not shown) disposed therein. The housing 1 comprises side panels 11, a bottom panel 12, and a top panel 13. Side panels 11 are provided with heat dissipation vents 111 for dissipating heat. A rain cover 112 is provided on the outer wall of the side panel 11, positioned at the heat dissipation vents 111. The rain cover 112 is curved and opens on one side near the bottom panel 12. A wire mesh 2 is provided on the inner wall of the side panel 11, positioned at the heat dissipation vents 111. To ensure effective heat dissipation, the wire mesh 2 is generally designed to be relatively thin. To ensure strength, the wire mesh 2 is made of stainless steel.

[0034] Reference Figure 1 and Figure 2 The housing 1 is entirely made of aluminum alloy with a certain thickness, and reinforcement ribs 3 are provided inside the housing 1 to ensure the structural strength of the housing 1. However, since the screen 2 is relatively thin, if it is made of aluminum alloy, the screen 2 will be insufficiently strong and easily deformed, making it difficult to meet the IP protection requirements.

[0035] Reference Figure 2 and Figure 3 A connector 4 is fixed to the inner wall of the housing 1 at the edge of the heat dissipation vent 111. The connector 4 is made of aluminum alloy and includes a connecting stud 41 welded to the inner wall of the housing 1 and a connecting nut 42 threadedly connected to the connecting stud 41. A stainless steel pressure plate 5 is also provided on the inside of the housing 1. The pressure plate 5 has a connection hole 51 for the connecting stud 41 to pass through.

[0036] Reference Figure 2 and Figure 3 Several fastening studs 43 are welded to the inner wall of the housing 1. The pressure plate 5 is also provided with several fastening holes (not shown) for the fastening studs 43 to pass through. Fastening nuts 44 are threaded onto the fastening studs 43. Both the fastening studs 43 and the fastening nuts 44 are made of aluminum alloy. The pressure plate 5 also has a receiving slot 53 for securing the wire mesh 2. The slot wall of the receiving slot 53 is provided with a through hole 54 that connects the heat dissipation port 111 with the interior of the housing 1, facilitating heat dissipation from the distribution box.

[0037] Reference Figure 3 The wire mesh 2 is welded to the wall of the receiving groove 53, ensuring a strong connection between the wire mesh 2 and the pressure plate 5. By first welding the aluminum alloy connecting studs 41 to the aluminum alloy side plate 11, and then pressing the stainless steel pressure plate 5 onto the side plate 11 via the connecting nuts 42, the wire mesh 2 is secured to the heat dissipation vent 111. This solves the problem of stainless steel wire mesh 2 being difficult to weld to the aluminum alloy side plate 11 due to differences in physical and chemical properties. Furthermore, the wire mesh 2 can be removed from the side plate 11, facilitating its replacement and maintenance.

[0038] The implementation principle of the aluminum alloy structure distribution box in the embodiment of the present application is as follows: the shell 1 is made of aluminum alloy material. Compared with the shell 1 made of stainless steel material, the overall weight of the distribution box is reduced, which is convenient for transportation and installation of the distribution box. When the wire mesh 2 needs to be installed on the side panel 11, it is only necessary to first fix the pressure plate 5 on the side panel 11 so that the connecting stud 41 extends into the connecting hole 51 and the fastening stud 43 extends into the fastening hole 52, and then tighten the connecting nut 42 on the connecting stud 41 and the fastening nut 44 on the fastening stud 43. It is easy to install. When the wire mesh 2 needs to be maintained, it is only necessary to loosen the connecting nut 42 to remove the pressure plate 5 and the wire mesh 2 from the side panel 11. The operation is convenient, so that the wire mesh 2 can be maintained separately without replacing the entire distribution box, saving resources and extending the service life of the distribution box.

[0039] Example 2 Reference Figure 4The difference between this embodiment and embodiment 1 is that a plurality of support rods 21 are fixed to the side of the screen 2 away from the pressure plate 5, and a cleaning plate 113 is rotatably provided on the inner wall of the heat dissipation port 111 near the top plate 13. The cleaning plate 113 is in an arc shape that fits with the rainproof cover 112. With the above arrangement, when the pressure plate 5 is installed on the side plate 11, the support rods 21 will press the cleaning plate 113 against the rainproof cover 112, so that the arc surface of the cleaning plate 113 fits together with the arc surface of the rainproof cover 112. When the pressure plate 5 and the screen 2 are removed, the support rods 21 no longer abut against the cleaning plate 113. At this time, the cleaning plate 113 will rotate in a direction away from the rainproof cover 112 under the action of gravity, thereby cleaning the heat dissipation port 111.

[0040] Reference Figure 4 When there are still debris in the heat dissipation port 111 after the cleaning plates 113 are cleaned, the heat dissipation port 111 can be cleaned separately by manually rotating one of the cleaning plates 113 without using additional cleaning tools, which is convenient and quick.

[0041] Reference Figure 4 and Figure 5 A fixing part 6 for fixing the wire mesh 2 is provided in the accommodating groove 53, and the fixing part 6 includes fixing springs 61 respectively arranged on the two groove walls of the accommodating groove 53 close to the connecting stud 41, and fixing blocks 62 respectively arranged on different fixing springs 61, wherein a guide inclined surface 621 is provided on the fixing block 62, and the guide inclined surface 621 is inclined along the direction in which the wire mesh 2 extends into the accommodating groove 53, and a fixing groove 622 for fixing the wire mesh 2 is also provided on the fixing block 62.

[0042] Reference Figure 4 and Figure 5 In this embodiment, the number of fixing springs 61 is preferably four, with two fixing springs 61 provided on each fixing block 62. In other cases, the specific number of fixing springs 61 can also be selected based on customer needs. The extension and contraction direction of the fixing springs 61 is perpendicular to the direction in which the wire mesh 2 extends into the receiving slot 53. Under the action of the fixing springs 61, the fixing blocks 62 move toward each other, so that the guide slopes 621 abut against the wire mesh 2 and are able to guide the wire mesh 2 into the receiving slot 53. This arrangement allows the wire mesh 2 to be disassembled and maintained separately. When the wire mesh 2 is damaged, only the pressure plate 5 does not need to be replaced, saving resources.

[0043] Reference Figure 6In order to reduce the risk of the connecting nut 42 loosening after long-term use, which may cause the pressure plate 5, the wire mesh 2 and the side plate 11 to separate, a locking member 7 is provided on the pressure plate 5 to prevent loosening. Two anti-slip grooves 511 are provided on the wall of the connecting hole 51. The locking member 7 includes a stop block 71 and a stop spring 72 provided in the anti-slip groove 511. The stop block 71 is slidably provided in the anti-slip groove 511. The stop spring 72 is connected to the wall of the anti-slip groove 511. The stop block 71 is fixed to the side of the stop spring 72 close to the connecting stud 41. Two limiting grooves 411 for the stop block 71 to extend into are provided on the circumferential side wall of the connecting stud 41.

[0044] Reference Figure 6 Through the above arrangement, when the connecting stud 41 extends into the connecting hole 51, the stop block 71 extends into the limiting groove 411 under the action of the stop spring 72. The groove wall of the limiting groove 411 can limit the stop block 71, thereby preventing the connecting stud 41 from moving out of the connecting hole 51, thereby increasing the connection strength between the pressure plate 5 and the side plate 11.

[0045] Reference Figure 6 A sliding groove 55 is provided on one side wall of the pressure plate 5 close to the connecting nut 42, and the sliding groove 55 is connected to the anti-slip groove 511. An unlocking member 8 is provided in the sliding groove 55 for moving the stop block 71 out of the limit groove 411. The unlocking member 8 includes a sliding block 81 slidably arranged in the sliding groove 55. A sliding hole 811 is provided on the sliding block 81 for the connecting stud 41 to pass through, and the inner diameter of the sliding hole 811 is larger than the diameter of the connecting stud 41.

[0046] Reference Figure 7 The two stop blocks 71 extend into the sliding groove 55, and the stop block 71 extends out of the pressure plate 5 along the anti-slip groove 511 and the sliding groove 55. The sliding block 81 is arranged between the two stop blocks 71, and the sliding block 81 extends out of the pressure plate 5, which is convenient for manual operation of the sliding block 81, so that the sliding block 81 slides in the sliding groove 55 toward or away from the wire mesh 2, and the width of the side of the sliding block 81 close to the wire mesh 2 is greater than the width of the side away from the wire mesh 2.

[0047] Reference Figure 6 and Figure 7 Through the above-mentioned setting, when the pressure plate 5 needs to be installed or removed from the side plate 11, it is only necessary to slide the sliding block 81 in the direction away from the wire mesh 2. At this time, the connecting stud 41 slides in the sliding hole 811, and the two stop blocks 71 move away from each other, so that the stop block 71 moves out of the limiting groove 411 and enters the anti-slip groove 511, thereby facilitating the connection stud 41 to move in or out of the connecting hole 51, thereby installing or removing the pressure plate 5.

[0048] Reference Figure 4 、 Figure 5 and Figure 6 To simplify the assembly and disassembly steps of the wire mesh 2, an unlocking slot 56 communicating with the sliding slot 55 is provided on the pressing plate 5. An unlocking plate 561 is slidably disposed in the unlocking slot 56. The unlocking plate 561 is fixedly connected to the sliding block 81, and the sliding direction of the unlocking plate 561 is consistent with the sliding direction of the sliding block 81. The unlocking plate 561 is connected to a retracting rod 562, which is connected to the fixing block 62. When the wire mesh 2 needs to be removed from the receiving slot 53, the sliding block 81 is simply slid away from the wire mesh 2, causing the two fixing blocks 62 to move away from each other. The wire mesh 2 can then be removed from the receiving slot 53, and the stop block 71 is simultaneously moved out of the limiting slot 411, thereby allowing the connecting stud 41 to move out of the connecting hole 51. The pressing plate 5 is then removed from the side plate 11, and the locking member 7 and fixing member 6 are simultaneously released, achieving simultaneous disassembly of the pressing plate 5 and the wire mesh 2, thereby improving the maintenance efficiency of the wire mesh 2.

[0049] Reference Figure 4 and Figure 5 When installing the pressure plate 5, slide the sliding block 81 in the direction away from the wire mesh 2. At this time, the wire mesh 2 may move in the direction of moving out of the receiving groove 53, but since the fixed block 62 is provided with a guide inclined surface 621, after releasing the sliding block 81, the fixed block 62 moves in the direction of approaching each other under the action of the fixed spring 61. At this time, the wire mesh 2 will still move in the direction of extending into the receiving groove 53 under the action of the guide inclined surface 621, thereby fixing the wire mesh 2 in the fixed groove 622.

[0050] The implementation principle of an aluminum alloy structure distribution box in an embodiment of the present application is: when the wire mesh 2 needs to be installed, you only need to slide the sliding block 81 first, so that the fixed block 62 and the stop block 71 move away from each other, and then place the wire mesh 2 in the accommodating groove 53, and then extend the connecting stud 41 into the connecting hole 51, and then loosen the sliding block 81, so that the stop block 71 extends into the limiting groove 411 and the wire mesh 2 is located in the fixing groove 622, and finally tighten the connecting nut 42 on the connecting stud 41, and tighten the fastening nut 44 on the fastening stud 43. The operation is simple, improves the connection stability of the pressure plate 5, the wire mesh 2 and the side panel 11, and facilitates the separate maintenance of the wire mesh 2.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
