Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, specifically to an electrical control cabinet. Background Technology

[0002] Electrical control cabinets are mainly used to control various power equipment, such as electric motors and generators. In industrial production, the starting, stopping, forward and reverse rotation, and speed regulation of electric motors can be achieved through components such as contactors and circuit breakers in the electrical control cabinet.

[0003] Electrical control cabinets generate a lot of heat during operation due to the large number of internal electrical components. In existing technology, the heat is mainly carried out from the inside of the cabinet by the air blowing action of the cooling fan through convection. However, since the air outlet of the cooling fan is in a single and fixed position, the cooling air is blocked by the electrical components and it is difficult to effectively carry the heat on the surface of the electrical components to the heat dissipation vent. This causes the heat to accumulate inside the cabinet, which in turn affects the internal convection heat dissipation effect of the cabinet.

[0004] Therefore, there is an urgent need for an electrical control cabinet to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical control cabinet, including a cabinet body, wherein the cabinet body is provided with a plurality of mounting rails for installing electrical components, and a cooling fan disposed on one side of the cabinet body, wherein the air inlet of the cooling fan is disposed away from the cabinet body and is fitted with a filter screen plate, wherein the side of the cabinet body away from the cooling fan is provided with a plurality of heat dissipation holes, wherein the cabinet body is provided with a shielding cover on the outer side wall for waterproofing and dustproofing each heat dissipation hole, and wherein the cabinet body is provided with an adjustment component for adjusting the air outlet of the cooling fan according to the layout of the electrical components.

The other end of each connecting pipe is fixedly connected to a conical air outlet hood. The installation pipe is provided with a support assembly for supporting each air outlet hood, and the connecting pipe is provided with a control assembly for controlling the passage of the air outlet hood.

[0007] The support assembly includes a support tube hinged to the side of the mounting tube near the air outlet hood. The support tube is slidably connected to a support rod. The end of the support rod away from the support tube is hinged to the side wall of the connecting tube. The side wall of the support tube is threaded with a bolt, and one end of the bolt abuts against the side wall of the support rod.

[0008] The control component includes a control rod rotatably connected to the connecting pipe, a control plate fixedly connected to the inner side wall of the connecting pipe, a limiting component for limiting the control plate in the connecting pipe, and a rotating ball fixedly connected to one end of the control rod outside the connecting pipe.

[0009] The limiting component includes a limiting frame fixedly connected to the control rod located on the outer side wall of the connecting tube. The limiting frame is connected to a limiting plate through a pressing component. The two opposite side walls of the limiting plate are provided with inclined surfaces.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-6 The diagram shows an electrical control cabinet, including a cabinet body 101. The cabinet body 101 is provided with multiple mounting rails 102 for installing electrical components. It also includes a cooling fan 2 located on one side of the cabinet body 101. The air inlet of the cooling fan 2 is located away from the cabinet body 101 and is fitted with a filter screen 3. Multiple heat dissipation holes 4 are opened on the side of the cabinet body 101 away from the cooling fan 2. The cabinet body 101 is provided with a shield 5 on the outer side wall for waterproofing and dustproofing each heat dissipation hole 4. The cabinet body 101 is provided with an adjustment component for adjusting the air outlet of the cooling fan 2 according to the layout of the electrical components.

[0023] It should be noted that during the use of this electrical control cabinet, by rationally arranging the electrical components inside the cabinet 101, the density of the electrical components is reduced. Under the action of the adjustment and support components, the air outlets of each air hood 605 are adjusted according to the installation status of each electrical component. This reduces the probability of cooling air being blocked by electrical components, ensures that cooling air can flow smoothly between electrical components, reduces heat accumulation, and thus improves the convection heat dissipation effect inside the cabinet 101.

[0024] It is worth noting that the electrical control cabinet mainly controls various power equipment through signal acquisition and transmission, signal processing and judgment, human-machine interface and monitoring, and safety protection functions. As this is existing technology, it will not be elaborated on here.

[0025] Please see Figures 1-4The adjustment component shown in the figure includes an air inlet pipe 601 disposed on the inner wall of the cabinet 101. One end of the air inlet pipe 601 is connected to the air outlet of the cooling fan 2, and the other end of the air inlet pipe 601 is fixedly connected to an installation pipe 602. The side of the installation pipe 602 near the electrical components is connected to a connecting pipe 604 through multiple corrugated pipes 603. The other end of each connecting pipe 604 is fixedly connected to a conical air outlet hood 605. The installation pipe 602 is provided with a support component for supporting each air outlet hood 605, and the connecting pipe 604 is provided with a control component for controlling the passage of the air outlet hood 605.

[0026] It should be noted here that by adjusting the settings of the components, the air outlet of the air outlet cover 605 can be adjusted accordingly based on the installation of the electrical components.

[0027] Please see Figure 3 and Figure 5 The support assembly shown in the figure includes a support tube 701 hinged to the side of the mounting tube 602 near the air outlet hood 605. The support tube 701 is slidably connected to a support rod 702. The end of the support rod 702 away from the support tube 701 is hinged to the side wall of the connecting tube 604. A bolt 703 is threadedly connected to the side wall of the support tube 701. One end of the bolt 703 is abutted against the side wall of the support rod 702.

[0028] It should be noted here that the support components are used to support and fix the adjusted air outlet hood 605, so as to maintain the positional stability of the air outlet hood 605.

[0029] Please see Figure 4 and Figure 6 The control component shown in the figure includes a control rod 801 rotatably connected to the connecting tube 604, a control plate 802 fixedly connected to the control rod 801 on the inner side wall of the connecting tube 604, a limiting component for limiting the control plate 802 in the connecting tube 604, and a rotating ball 803 fixedly connected to one end of the control rod 801 on the outside of the connecting tube 604.

[0030] It should be noted here that by setting the control components, the air outlet duct of the air outlet hood 605 can be opened and closed according to the installation status of the electrical components, thereby achieving targeted cooling of the electrical components and providing the best cooling effect to the electrical components while keeping the power of the cooling fan 2 unchanged.

[0031] Working principle: When using this electrical control cabinet, firstly, the various mounting rails 102 are fixed in an orderly manner according to the electrical components to be installed. Then, the electrical components are reasonably arranged on the mounting rails 102. After the installation and fixing of each electrical component is completed, the air outlets of each air hood 605 can be adjusted according to the installation status of each electrical component. During the adjustment of each air outlet, the hinged support pipe 701 and support rod 702 can be rotated. Under the extension and contraction of the support rod 702 and the deformation of the corrugated pipe 603, the air outlet hood 605 at one end of the connecting pipe 604 is set between two adjacent rows of electrical components.

[0032] After adjusting the air outlet of the air outlet 605, the air outlet channel of the air outlet 605 can be opened by the control component. The air outlet channel of the air outlet 605 on the side without electrical components is closed under the action of the control component, thereby achieving targeted cooling of the electrical components. This allows the cooling fan 2 to provide the best cooling effect to the electrical components without changing the power.

[0033] After adjusting the air outlet of the air hood 605 and opening and closing the air outlet channel, the cooling fan 2 can be started. Under the blowing action of the cooling fan 2, the cooling air flows from the air inlet pipe 601 to the mounting pipe 602, and finally blows from the air hoods 605 with the air outlet channels open to both sides of the electrical components. The cooling air carrying heat flows out from the heat dissipation holes 4, thereby realizing the convective heat dissipation of the electrical components inside the cabinet 101. Since each air hood 605 is located on both sides of each electrical component under the action of the adjustment component and the support component, the probability of the cooling air being blocked by the electrical components is reduced, ensuring that the cooling air can flow smoothly between the electrical components, reducing the accumulation of heat, and thus improving the convective heat dissipation effect inside the cabinet 101.

[0034] Example 2

[0035] Please see Figure 6 This embodiment further illustrates Example 1. The limiting component shown in the figure includes a limiting frame 901 fixedly connected to the control rod 801 located on the outer side wall of the connecting tube 604. The limiting frame 901 is connected to a limiting plate 902 through a pressing component. The two opposite side walls of the limiting plate 902 are provided with inclined surfaces 903. The side wall of the connecting tube 604 is fixedly connected to two U-shaped plates 904 set at ninety degrees.

[0036] It should be noted that, through the setting of the limiting component, during the rotation of the control rod 801, the limiting plate 902 on the limiting frame 901 will rotate. When the limiting plate 902 abuts against the side wall of the U-shaped plate 904, under the interaction force of the inclined surface 903 and the guiding action of the pressing component, the limiting plate 902 will be pushed to retract into the limiting frame 901. When the limiting plate 902 is rotated to be opposite another U-shaped plate 904, the limiting plate 902 will be inserted into the U-shaped plate 904 under the elastic action of the pressing component and abut against the bottom wall of the U-shaped plate 904. Thus, under the pressing action of the limiting plate 902, the control rod 801 is limited, and the control plate 802 is further limited, thereby ensuring the positional stability of the control plate 802 in different states.

[0037] Please see Figure 6 The extrusion assembly shown in the figure includes an extrusion plate 1001 that is slidably connected to a limiting frame 901. One end of a limiting plate 902 is connected to the extrusion plate 1001. A spring 1002 is fixedly connected to the side of the extrusion plate 1001 away from the limiting plate 902. The other end of the spring 1002 is connected to the bottom wall of the limiting frame 901.

[0038] It should be noted here that the compression component is designed to guide and reset the movement of the limit plate 902.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
