Description

Technical Field

[0001] The utility model relates to a switch cabinet, in particular to a dustproof structure of the switch cabinet. Background Art

[0002] Switchgear plays a role of switching, controlling and protecting in the power generation, transmission and distribution, and power conversion of the power system. Especially in the transformer, the substation will be equipped with a switchgear with a transformer installed on one side of the high-voltage busbar, which can reduce the high voltage of 10kV to the low voltage of 380V, and provide power for the 220V and 380V used in the substation. In the process of voltage conversion, a lot of heat will be generated, so generally holes need to be opened on the switchgear for heat dissipation. After the heat dissipation holes are set, external dust will enter the interior of the switchgear through the heat dissipation holes, affecting the performance of the electrical components in the equipment.

[0003] The existing dust-proof structure of the switch cabinet often adopts the method of making the heat dissipation holes inclined to prevent dust from entering the interior of the switch cabinet through the heat dissipation holes in a straight line. However, if the heat dissipation holes are too large, it is easy for a large amount of dust such as water to overflow into the heat dissipation holes, and the dust-proof effect is weak. If the heat dissipation holes are too small, it is easy for the heat to not be dissipated in time. Although the dust-proof effect is improved, the heat cannot be removed in time, which runs counter to the purpose of setting the heat dissipation holes.

[0004] Therefore, this case aims to provide a dustproof structure for a switch cabinet, which can not only effectively prevent dust under normal conditions and prevent a large amount of dust from entering the equipment, but also can promptly and quickly remove heat without affecting the heat dissipation effect of the equipment. Utility Model Content

[0005] The utility model provides a dustproof structure for a switch cabinet, which can effectively solve the above problems.

[0006] The utility model is achieved in this way:

[0007] A dustproof structure of a switch cabinet, comprising: a mounting card plate matched with the switch cabinet, a bent clamp plate is provided on the side of the mounting card plate facing the switch cabinet, at least two mounting holes are provided on the mounting card plate, a plurality of heat sinks are provided on the front of the mounting card plate, and the heat sink and the mounting card plate form a heat dissipation channel, and the dustproof structure also includes:

[0008] The air-guiding dust-blocking assembly, wherein the heat sink protrudes outward toward a side away from the mounting card plate, and the air-guiding dust-blocking assembly comprises an inclined barrier seat arranged in the heat dissipation channel, and the barrier seats in the same row are connected by a horizontal axis, and the hot air in the switch cabinet is guided by the barrier seat and discharged downward through the inner wall of the heat sink.

[0009] As a further improvement, the barrier seat includes a connecting guide plate that fits the bottom edge of the heat dissipation channel and is connected to the horizontal axis. An inclined seat is arranged above the connecting guide plate, and the inclined seat gradually extends in height along one side of the hot air output.

[0010] As a further improvement, a screen is provided on one side of the upper edge of the inclined seat close to the heat sink.

[0011] As a further improvement, the tilting angle of the tilting seat is 25 to 30 degrees.

[0012] As a further improvement, the heat sink is an outer arc plate structure away from the mounting card plate, and the hot air is guided by the inclined seat and discharged downward through the outer arc plate structure.

[0013] As a further improvement, the transverse axis is fixed in the heat dissipation channel, and the distance between the inclined seat and the inner side wall of the heat sink is fixed.

[0014] As a further improvement, the side of the transverse axis away from the heat sink is driven by a driving structure, and the driving structure includes a guide arm connected to the transverse axis, and the guide arm is driven by two push rod motors.

[0015] As a further improvement, the two push rod motors are mounted on the side walls of the mounting card.

[0016] The beneficial effects of the utility model are:

[0017] In the existing dust-proof structure, the size of the heat dissipation hole opening is always controversial. If the opening is large, although it is conducive to heat dissipation, the dust-proof effect is poor. If the opening is small, although it is not conducive to heat dissipation, the dust-proof effect is higher. In this regard, the utility model adds an air-guiding dust-blocking component. First, the diameter of the entire heat dissipation channel is enlarged to ensure a certain ventilation effect. Then, a barrier seat is set in the heat dissipation channel, so that the inclined barrier seat can prevent dust from entering the equipment while guiding the hot air to be discharged, thereby avoiding the influence of the dust treatment effect after the aperture is expanded. At the same time, the linkage setting of the horizontal axis and the barrier seat can achieve the effect of precise fixing and movement, whether in the stage of installing the fixed barrier seat or setting the barrier seat to be movable.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0024] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] Reference Figure 1 to Figure 4As shown, a dustproof structure of a switch cabinet comprises: a mounting card plate 10 matched with the switch cabinet, a bent clamp plate 20 is provided on the side of the mounting card plate 10 facing the switch cabinet, at least two mounting holes are provided on the mounting card plate 10, a plurality of heat sinks 30 are provided on the front of the mounting card plate 10, the heat sink 30 and the mounting card plate 10 form a heat dissipation channel A, the dustproof structure further comprises: an air-guiding dust-blocking component, the heat sink 30 protrudes outward toward the side away from the mounting card plate 10, the air-guiding dust-blocking component comprises an inclined barrier seat 41 arranged in the heat dissipation channel A, the barrier seats 41 in the same row are connected by a horizontal axis 42, and the hot air in the switch cabinet is guided by the barrier seat 41 and then discharged through the inner wall of the heat sink 30.

[0026] During installation, the mounting card plate 10 is locked onto the switch cabinet through the mounting hole, and in order to improve the sealing and matching effect, the outer wall of the mounting card plate 10 is bent to form a bent clamping plate 20, so that it can better match with the switch cabinet.

[0027] exist Figure 1 It can be seen that the heat sink 30 in this embodiment is arranged at a higher density, and correspondingly, the number of the barrier seats 41 and the horizontal axis 42 is also larger. If the intervals between the heat sinks 30 are larger, resulting in a smaller purpose of the heat sink 30, then the number of the barrier seats 41 and the horizontal axis 42 is also reduced accordingly.

[0028] In the stage of setting the heat dissipation channel A, the width of the existing heat sink is generally 3-4 cm. However, in this embodiment, the width of the heat dissipation channel A is set to 6 cm, thereby increasing the exhaust speed of hot air.

[0029] After the heat dissipation channel A becomes larger, this embodiment adds an air-guiding dust-blocking component. First, the diameter of the entire heat dissipation channel A is enlarged to ensure a certain ventilation effect, and then a blocking seat 41 is set in the heat dissipation channel A, so that the inclined blocking seat 41 can prevent dust from entering the equipment while guiding the hot air to be discharged, thereby avoiding the influence of the dust treatment effect after the aperture is enlarged. At the same time, the linkage setting of the horizontal axis 42 and the blocking seat 41 can achieve the effect of precise fixing and movement, whether in the stage of installing and fixing the blocking seat 41 or setting the blocking seat 41 to be movable.

[0030] Specifically, the barrier seat 41 includes a connecting guide plate 411 that is in contact with the bottom edge of the heat dissipation channel A and connected to the horizontal axis 42. An inclined seat 412 is arranged above the connecting guide plate 411. The inclined seat 412 gradually extends in height along one side of the hot air output. Since the inclined seat 412 is lower on the left and higher on the right, the hot air can be guided outward while dust cannot enter from the higher end, thereby greatly improving the heat dissipation and dust blocking effect.

[0031] However, if the height of the inclined seat 412 is simply increased, it is not conducive to the discharge of hot air. Therefore, the inclination angle of the inclined seat 412 in this embodiment is 25 to 30°, and the actual selection is generally around 30°, so as to achieve the guiding effect without causing obstruction.

[0032] In order to improve the hot air guidance effect, the heat sink 30 is an outer arc plate structure away from the mounting card plate 10. The hot air is guided by the inclined seat 412 and then discharged downward through the outer arc plate structure. Although the arc-shaped convex design of the heat sink 30 is an existing structure, it can achieve the effects of gas storage, gas stagnation and gas guidance when used in conjunction with the inclined inclined seat 412.

[0033] In this embodiment, the entire air-guiding and dust-blocking assembly is in a fixed setting state, that is, the positions of the horizontal axis 42 and the inclined seat 412 always remain unchanged. Specifically, the horizontal axis 42 is fixed in the heat dissipation channel A, and the distance between the inclined seat 412 and the inner wall of the heat sink 30 is fixed, achieving a fixed adjustment effect.

[0034] In other embodiments, the entire air guide and dust blocking assembly can be movably arranged. Specifically, the side of the horizontal axis 42 away from the heat sink 30 is driven by a driving structure, and the driving structure includes a guide arm 51 connected to the horizontal axis 42. The guide arm 51 is driven by two push rod motors 52, thereby achieving the effect of adjusting the width of the heat dissipation channel A.

[0035] In order to improve the dust blocking effect of the air-guiding dust blocking assembly, a screen 413 is provided on the upper edge of the inclined seat 412 close to the heat sink 30. When the driving structure is pushed to the stroke limit, the screen 413 fits against the inner wall of the heat sink 30. The screen 413 can also be set without setting a driving structure, and only the position cannot be adjusted, but the dust blocking effect still exists.

[0036] In order to prevent the hot air from directly affecting the push rod motor 52, the two push rod motors 52 are installed on the side walls of the mounting card 10, and a barrier setting is performed, such as setting a partition, an accordion cover, an interlayer, etc. to slightly separate the push rod motor 52 from the flow path of the hot air, so as to prevent the high temperature hot air from continuously affecting the push rod motor 52.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
