Description

Technical Field

[0001] The invention relates to the technical field of power supply equipment, and in particular to a modular outdoor rectifier cabinet and a processing device thereof. Background Art

[0002] A rectifier cabinet is a device used in power electronic systems. Its main function is to convert alternating current into direct current; this conversion process is called rectification.

[0003] In the prior art, outdoor rectifier cabinets, as key components in power conversion systems, are usually deployed in outdoor environments with relatively harsh environmental conditions. In order to ensure that the electronic components inside the rectifier cabinets can still operate stably under adverse conditions such as high temperature, humidity or dust, their design must take into account both efficient heat dissipation performance and excellent sealing.

[0004] However, the existing outdoor rectifier cabinets still have the following defects during use:

[0005] In the design of outdoor rectifier cabinets, achieving a balance between efficient heat dissipation and good sealing is a major challenge. It is often difficult to have both: increasing ventilation to improve heat dissipation efficiency will weaken the sealing effect and threaten equipment safety; while enhancing sealing may restrict air circulation, causing heat accumulation, affecting the operating temperature of components, reducing efficiency and shortening life. Summary of the invention

[0021] Beneficial effects of the present invention:

[0022] 1. By setting up a heat dissipation mechanism, the driving mechanism is responsible for controlling the rotation of the heat dissipation plate. When the heat dissipation plate starts to rotate and the through hole opens, this action also causes the filter cloth connected to it to gradually unfold. In this way, while ensuring the air circulation efficiency, the impurities in the air are effectively filtered through the filter cloth, achieving the dual functions of ventilation and isolation of dust and other undesirable substances. When the heat dissipation plate is fully unfolded, the angle between it and the through hole formed on the side of the upper cabinet exceeds sixty degrees. This design ensures that the unfolding area of ​​the filter cloth is larger than the cross-sectional area of ​​the through hole. Therefore, the outside air is first introduced into the system through the filter cloth. This structure not only increases the amount of air introduced, but also enhances the heat dissipation efficiency and filtering effect, thereby effectively improving the operating performance and stability of the overall equipment.

[0023] 2. By setting a driving mechanism, the distance between the lower cabinet and the upper cabinet of the two modular structures can be adjusted, so that when the temperature inside the rectifier cabinet is high, the overall space inside the rectifier cabinet can be increased to form a negative pressure, so that the outside air can be quickly sucked into the rectifier cabinet body for cooling; at the same time, the driving mechanism can synchronously drive the heat sink to rotate, so that the through hole is opened, further improving the heat dissipation effect;

[0024] 3. By setting up a tensioning mechanism, the winding mechanism can be driven to unwind through the linkage mechanism during the rotation of the heat sink. During this process, the filter cloth can be unfolded in a tensioned state, so that the heat sink can effectively filter the air through the filter cloth when rotating at different angles, ensuring the filtering effect, realizing ventilation and heat dissipation work under different temperature conditions in the rectifier cabinet body, and ensuring that the rectifier cabinet body is effectively isolated from the outside world, ensuring safety in use and service life;

[0025] 4. By setting up a control mechanism, the pressure applied is controlled to cause the clamping block to deform and bend, so as to firmly clamp the limiting shaft, thereby achieving stable locking of the filter cloth; when the clamping block is bent and tightly matched with the limiting shaft, it and the winding shaft together form a circular structure with a standard outer diameter; this design ensures that the filter cloth can be rolled and unfolded evenly and stably, maintaining smoothness and consistency during operation.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] A modular outdoor rectifier cabinet, please refer to Figure 1-Figure 2 , including a rectifier cabinet body 1 with a ventilation net 2; a heat dissipation mechanism 3 is arranged on the side wall of the rectifier cabinet body 1; the heat dissipation mechanism 3 includes a heat sink 31, a filter cloth 32 and a driving mechanism 33. Among them, a through hole is opened on the rectifier cabinet body 1; the heat sink 31 is hinged to the rectifier cabinet body 1 and is used to open or close the through hole; it can be understood that the heat sink 31 has good thermal conductivity, such as aluminum alloy; when there is no need for better heat dissipation in the rectifier cabinet body 1, the heat sink 31 closes the through hole, and the heat is dissipated by the thermal conductivity of the heat sink 31, ensuring a good sealing effect of the rectifier cabinet body 1 when used outdoors; when the temperature in the rectifier cabinet body 1 is high, the heat sink 31 is driven to rotate and the through hole is opened, so that the outside air can enter the rectifier cabinet body 1 for rapid ventilation and heat dissipation, thereby improving the heat dissipation efficiency.

[0042] See also Figure 1-Figure 2 The filter cloth 32 is arranged between the through hole and the heat sink 31; the driving mechanism 33 is arranged on the rectifier cabinet body 1, and the driving mechanism 33 is used to drive the heat sink 31 to rotate; when the driving mechanism 33 drives the heat sink 31 to rotate, the filter cloth 32 can be driven to unfold, so that the outside air can enter the rectifier cabinet body 1 after being filtered by the filter cloth 32.

[0043] It should be noted that, when the through hole of the heat sink 31 is opened, the outside air is directly connected to the inside of the rectifier cabinet body 1. At this time, due to the complex outdoor environment, the outside air is directly connected to the inside of the rectifier cabinet body 1, which is easy to bring in moisture and dust. Therefore, a filter cloth 32 is provided to achieve filtering and ensure that the rectifier cabinet body 1 is relatively isolated from the outside. Specifically, the heat sink 31 is driven to rotate by the driving mechanism 33, and then the filter cloth 32 can be driven to unfold, so that the air is filtered by the filter cloth 32. It should be noted that the filter cloth 32 is provided on multiple sides of the heat sink 31, that is, when the heat sink 31 is rotated to open the through hole, the outside air can only enter the rectifier cabinet body 1 through the through hole after being filtered by the filter cloth 32.

[0044] When the heat sink 31 is fully expanded, the angle between it and the through hole exceeds sixty degrees. This design ensures that the expanded area of ​​the filter cloth 32 is larger than the cross-sectional area of ​​the through hole. Therefore, the outside air is first introduced into the system through the filter cloth 32. This structure not only increases the amount of air introduced, but also enhances the heat dissipation efficiency and filtering effect, thereby effectively improving the operating performance and stability of the overall equipment.

[0045] See also Figure 1-Figure 6 In order to ensure that the filter cloth 32 is in a tightened state when the heat sink 31 rotates at different angles, which is conducive to filtering air, a tightening mechanism 34 is provided; specifically, the heat sink 3 also includes a tightening mechanism 34; the tightening mechanism 34 is used to keep the filter cloth 32 in a tightened state during the rotation of the heat sink 31; the tightening mechanism 34 includes a retracting mechanism 341, a linkage mechanism and a pair of baffles 343; the filter cloth 32 is wound around the retracting mechanism 341, and the pair of baffles 343 are provided on the rectifier cabinet body 1; the linkage mechanism is provided on the baffle 3 43 and the winding mechanism 341; when the heat sink 31 rotates, the filter cloth 32 can be driven to unwind or rewind through the linkage mechanism; it can be understood that during the rotation of the heat sink 31, the opposite side surfaces of the heat sink 31 are always in close contact with the baffle 343, as in the accompanying drawings used as an example, the baffle 343 is in close contact with the left and right side surfaces of the heat sink 31; at this time, one end of the filter cloth 32 is connected to a side of the heat sink 31 away from the rotating position, and the other end of the filter cloth 32 is connected to the side wall of the through hole away from the rotating position of the heat sink 31.

[0046] It should be noted that when the heat sink 31 is driven by the driving mechanism 33 to rotate and open the through hole, as the heat sink 31 rotates, the winding mechanism 341 is driven to unwind through the linkage mechanism. In this process, the filter cloth 32 can be unfolded in a taut state, so that the heat sink 31 can effectively filter the air through the filter cloth 32 when rotating at different angles, thereby ensuring the filtering effect, realizing ventilation and heat dissipation work under different temperature conditions in the rectifier cabinet body 1, and ensuring that the rectifier cabinet body 1 is effectively isolated from the outside world, thereby ensuring safety of use and service life.

[0047] See also Figure 5-Figure 7 The winding mechanism 341 includes a winding shaft 3411 and a limiting shaft 3413; the middle position of the filter cloth 32 is connected to the limiting shaft 3413, the limiting shaft 3413 is fixed to the winding shaft 3411, and the filter cloth 32 is wound around the winding shaft 3411; it should be noted that when the middle part of the filter cloth 32 is fixed to the limiting shaft 3413 and the winding shaft 3411 is driven to rotate by the linkage mechanism, the folded filter cloth 32 is wound or unwound on the winding shaft 3411 in one direction; and the filter cloth 32 can be quickly wound or unwound by the winding shaft 3411 with a larger diameter to adapt to the rotation of the heat sink 31.

[0048] See also Figure 2 and Figure 4-Figure 7 , the present application does not limit the specific structure and installation method of the linkage mechanism, and only provides a feasible technical solution below; the linkage mechanism includes a pair of gears 342, the pair of gears 342 are coaxially fixed on the winding shaft 3411, a first slide groove 344 is provided on the baffle 343, and a tooth groove 345 meshing with the gear 342 is provided in the first slide groove 344; the first slide groove 344 is an arc groove structure with the rotation point of the heat sink 31 as the center; when the heat sink 31 rotates, it can drive the gear 342 to slide along the arc groove; a torsion spring 346 is provided between the winding shaft 3411 and the gear 342; the gear 342 is coaxially sleeved on the winding shaft 3411, and the gear 342 and the winding shaft 3411 are connected by the torsion spring 346.

[0049] It should be noted that when the heat sink 31 rotates, the gear 342 on the winding shaft 3411 is driven to slide in the first slide groove 344, and the gear 342 can be driven to rotate through the tooth groove 345, and then the winding shaft 3411 is driven to rotate, so as to realize the unwinding or winding of the filter cloth 32, so that the filter cloth 32 is in a taut state during the unwinding or winding process, that is, the heat sink 31 can stay in any angle range at this time, so that the through hole can be opened to any degree for ventilation, which is convenient for use in conjunction with the temperature change in the rectifier cabinet body 1, ensuring effective heat dissipation and sealing isolation balance, which is conducive to outdoor use.

[0050] See also Figure 1-Figure 4 The rectifier cabinet body 1 includes a lower cabinet 11, an upper cabinet 12 and a protective door 14 with a door frame 13; the door frame 13 is fixed to the lower cabinet 11, and the upper cabinet 12 is slidably connected to the door frame 13; a slot 15 is provided at the bottom of the lower cabinet 11, and a plug board matched with the slot 15 is fixed at the top of the upper cabinet 12, and the lower cabinet 11 is connected to the upper cabinet 12 through the slot 15 and the plug board.

[0051] It should be noted that, in order to improve the convenience of transportation, the rectifier cabinet body 1 is generally designed as a modular assembly structure, that is, the rectifier cabinet body 1 is assembled from a lower cabinet 11, an upper cabinet 12, a door frame 13 and a protective door 14; and the electronic components in the rectifier cabinet body 1 are installed in the lower cabinet 11 through a mounting plate, and the mounting plate extends upward into the lower cabinet 11, and the mounting plate and the lower cabinet 11 are slidably connected through a slide rail; and through the coordinated use of the slot 15 and the plug-in board, the assembly convenience and stability of the lower cabinet 11 and the upper cabinet 12 can be improved.

[0052] See also Figure 1-Figure 2 , Figure 4 and Figure 8 The driving mechanism 33 includes a first driving member 331 and a connecting rope 332; it can be understood that the first driving member 331 is a prior art, such as the cylinder structure in the attached figure as an example; the first driving member 331 is installed between the lower cabinet 11 and the upper cabinet 12, the heat dissipation mechanism 3 is arranged on the upper cabinet 12, one end of the connecting rope 332 is wrapped around the rotation connection position of the heat dissipation plate 31, and the other end of the connecting rope 332 is fixed to the lower cabinet 11; when the first driving member 331 drives the upper cabinet 12 away from the lower cabinet 11, the connecting rope 332 is tightened, so that the connecting rope 332 drives the heat dissipation plate 31 to rotate; a second slide groove 333 is opened on the baffle 343, and the connecting rope 332 is slidably connected to the second slide groove 333.

[0053] It should be noted that when there is a greater demand for heat dissipation in the rectifier cabinet body 1, the upper cabinet body 12 is first driven to rise through the driving mechanism 33, so that the upper cabinet body 12 is separated from the lower cabinet body 11. At this time, the overall space inside the rectifier cabinet body 1 increases to form a negative pressure, and then the outside air can be quickly sucked into the rectifier cabinet body 1 for cooling; and in the process of the upper cabinet body 12 moving upward, the rectifier cabinet body 1 is still relatively isolated from the outside world through the setting of the slot 15 and the plug board, and the operation of the electronic components inside the rectifier cabinet body 1 is not affected; and as the upper cabinet body 12 continues to move upward, the connecting rope 332 is tightened, and the heat sink 31 is pulled to rotate by the connecting rope 332, so as to drive the through hole to open, thereby further increasing the ventilation volume of the outside air entering the rectifier cabinet body 1 and improving the heat dissipation effect.

[0054] See also Figure 9-12A processing device for a modular outdoor rectifier cabinet includes a mounting seat 4 and a control mechanism 5 arranged on the mounting seat 4; a winding shaft 3411 is arranged on the mounting seat 4, and a limiting shaft 3413 is arranged in a limiting groove 3412 of the winding shaft 3411; a limiting groove 3412 matched with the limiting shaft 3413 is opened on the winding shaft 3411, and the limiting shaft 3413 is arranged in the limiting groove 3412; a clamping block 3414 is arranged on the winding shaft 3411; the control mechanism 5 is used to squeeze the clamping block 3414, so that it is deformed and cooperates with the winding shaft 3411 to cover the limiting shaft 3413.

[0055] It should be noted that it is necessary to ensure that the heat sink 31 (such as Figure 5 As shown in FIG. 1 ), the filter cloth 32 (as shown in FIG. Figure 5 As shown in the figure, the filter cloth 32 is always kept in a taut state during winding and unwinding, so the filter cloth 32 needs to have a certain initial winding diameter to adapt to the rotation speed of the heat sink 31; and if the middle position of the filter cloth 32 is pasted on the winding shaft 3411, the filter cloth 32 is easily caused to fall off from the winding shaft 3411 during the frequent use of the filter cloth 32 driven by the heat sink 31, which affects the service life. Therefore, the middle position of the filter cloth 32 is fixed on the winding shaft 3411 by setting an extrusion locking method, thereby improving the service life of the filter cloth 32;

[0056] Specifically: first, the winding shaft 3411 is positioned on the mounting seat 4, and then the limiting shaft 3413 is placed in the limiting groove 3412; then, the clamping block 3414 is squeezed by the control mechanism 5 to cause it to deform, until the clamping block 3414 bends and clamps the limiting shaft 3413, thereby completing the clamping and locking of the filter cloth 32. At this time, the clamping block 3414 and the winding shaft 3411 together form a circular structure with a standard outer diameter, so as to facilitate the uniform winding and unfolding of the filter cloth 32.

[0057] See also Figure 9-12 The control mechanism 5 includes a mounting frame 51, a plurality of extrusion wheels 52 and two groups of second driving members 53; it can be understood that the second driving member 53 is a prior art, such as the cylinder structure in the exemplary figure; the plurality of extrusion wheels 52 are rotatably connected to the mounting frame 51; the plurality of second driving members 53 are arranged on the mounting seat 4; the output ends of the two groups of second driving members 53 are both connected to the mounting frame 51, and the axis of the output shaft of the second driving member 53 is kept perpendicular to the axis of the winding shaft 3411, so that the extrusion wheel 52 can face the extrusion clamping block 3414.

[0058] It should be noted that when the limiting shaft 3413 is assembled with the winding shaft 3411, the second driving member 53 drives the mounting frame 51 to move, thereby driving the multiple extrusion wheels 52 to move, and the extrusion wheels 52 squeeze the clamping block 3414 until the clamping block 3414 is close to the limiting shaft 3413, thereby locking the filter cloth 32.
