Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a frequency converter cabinet and a soft water production line. Background Technology

[0002] Currently, when making process improvements in a soft water production line, some equipment, such as the power distribution cabinet, needs to be modified to save costs. For example, some power distribution cabinets may be converted into frequency converter cabinets by adding frequency converters to change the frequency and amplitude of the power supply, thereby realizing the frequency conversion function of the pumps in the soft water production line.

[0003] In the existing technology, some old distribution cabinets only rely on natural ventilation for heat dissipation. Since frequency converters generate a lot of heat when they are working, the heat dissipation effect of natural ventilation is limited. Therefore, when converting old distribution cabinets into frequency converter cabinets, cooling fans are usually added inside the cabinet.

[0004] However, the inventors discovered that in actual use, in order to keep the cooling fan working properly, it is necessary to clean the cooling fan regularly, but the cooling fan may be blocked by other parts, making the cleaning operation difficult. Utility Model Content

[0005] The problem solved by this invention is how to reduce the difficulty of cleaning the cooling fan.

[0006] On one hand, this utility model provides a frequency converter cabinet, including a cabinet body, a door panel and a cooling fan; the cabinet body has an internal accommodating cavity; the door panel is used to open or close the accommodating cavity; the door panel has a vent communicating with the accommodating cavity; the cooling fan is installed on the end face of the door panel facing the inside of the accommodating cavity, and the cooling fan covers the vent.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; and the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0031] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0032] like Figure 1 , 2 As shown, this utility model provides a frequency converter cabinet, including a cabinet body 1, a door panel 2, and a cooling fan 3; the cabinet body 1 has an internal accommodating cavity 11; the door panel 2 is used to open or close the accommodating cavity 11; the door panel 2 has a vent 21 communicating with the accommodating cavity 11; the cooling fan 3 is installed on the end face of the door panel 2 facing the inside of the accommodating cavity 11, and the cooling fan 3 covers the vent 21.

[0033] Specifically, the shape of the cabinet body 1 is not limited and depends on actual needs. For example... Figure 1 As shown, the cabinet body 1 is rectangular in shape and has an internal cavity 11. The cabinet body 1 has an opening on its front face that communicates with the cavity 11. A door panel 2 is rotatably positioned at the opening to open or close the cavity 11. The door panel 2 has a through-hole vent 21 along its thickness direction. After the door panel 2 closes the cavity 11, the vent 21 remains open. A cooling fan 3 is installed on the end face of the door panel 2 facing the interior of the cavity 11, and the cooling fan 3 covers the vent 21. Figure 3 As shown, the top of the cabinet body 1 is provided with a cover 12, and the side wall of the cover 12 is provided with a vent 121 communicating with the accommodating cavity 11; when the cooling fan 3 is an intake fan, the vent 121 on the side wall of the cover 12 is an exhaust fan; when the cooling fan 3 is an exhaust fan, the vent 121 on the side wall of the cover 12 is an intake fan.

[0034] In this embodiment, the cooling fan 3 covers the vent 21 of the door panel 2. The cooling fan 3 can realize the flow of air inside the cabinet body 1 from the vent 21 of the door panel 2, so as to realize the heat dissipation of the internal components of the inverter cabinet, such as the inverter 8. When it is necessary to clean the cooling fan 3, the door panel 2 is opened first. Since the cooling fan 3 is installed on the end face of the door panel 2 facing the inside of the accommodating cavity 11, the cooling fan 3 can be exposed when the door panel 2 is fully opened, which makes it easier for the operator to clean the cooling fan 3. Since there is no interference from other components inside the inverter cabinet, the difficulty of cleaning is effectively reduced.

[0035] Optionally, the cooling fan 3 is installed in the middle or lower part of the door panel 2.

[0036] It should be noted that the cabinet body 1 is generally quite tall, between 1.8 meters and 2.2 meters. Operators can only clean the cooling fan 3 when it is installed in a suitable position. Generally, the cooling fan 3 is installed in the middle or lower part of the door panel 2.

[0037] like Figure 1 As shown, the cooling fan 3 is installed at the bottom of the door panel 2, about 50cm from the ground. This way, when the door panel 2 is opened, the cooling fan 3 is exposed within the operator's reach, making it easy to clean.

[0038] Optionally, the cooling fan 3 includes a mounting bracket 31 and a fan body 32; the mounting bracket 31 is connected to the door panel 2 and has a through mounting channel 311; the fan body 32 is installed in the mounting channel 311; at least a portion of the vent 21 is located within the projection range of the mounting channel 311 on the door panel 2.

[0039] Specifically, the cooling fan 3 includes a mounting bracket 31 and a fan body 32; the outer contour shape of the mounting bracket 31 can be square, circular, or other irregular shapes, without limitation, depending on actual needs. Figure 1 As shown, the outer contour of the mounting bracket 31 is square, and it is connected to the door panel 2 and has a through mounting channel 311; the fan body 32 is mounted at the center of the mounting channel 311 by a bracket; at least part of the vent 21 is located within the projection range of the mounting channel 311 on the door panel 2.

[0040] In this optional embodiment, when installing the cooling fan 3, the mounting bracket 31 is first fixedly connected to the door panel 2. At this time, at least part of the vent 21 is located within the projection range of the mounting channel 311 on the door panel 2. Thus, when the cooling fan 3 is an intake fan, the operation of the cooling fan 3 can drive the airflow through the vent 21 into the interior of the cabinet body 1, thereby achieving heat dissipation inside the cabinet body 1.

[0041] Optionally, it also includes a first quick-release structure and a second quick-release structure, and the mounting bracket 31 is detachably connected to the door panel 2 through the first quick-release structure and the second quick-release structure.

[0042] It is important to understand that the cooling fan 3 is installed on the cabinet body 1, so one side of the cooling fan 3 faces the cabinet body 1. When the cooling fan 3 is not disassembled, the side facing the cabinet body 1 cannot be cleaned or can only be cleaned through the air vent 21 of the cabinet body 1, which will result in poor overall cleaning effect.

[0043] In this optional embodiment, the mounting bracket 31 is detachably connected to the door panel 2 via a first quick-release structure and a second quick-release structure, thereby enabling the quick installation and separation of the cooling fan 3 and the door panel 2.

[0044] Optionally, the first quick-release structure includes a mounting post 4 connected to the door panel 2, and the mounting post 4 is provided with a T-shaped track slot 41 with one end open along its length; the second quick-release structure includes a T-shaped guide block 5 connected to the side end face of the mounting bracket 31; the T-shaped guide block 5 is slidably connected to the T-shaped track slot 41.

[0045] Specifically, such as Figure 4 , 5 As shown, the mounting post 4 is vertically mounted on the door panel 2, and the connection between the two is not limited to welding or screw connection. The mounting post 4 has a T-shaped track groove 41 with an open top along its length; the T-shaped guide block 5 is mounted on the side end face of the mounting bracket 31, and the connection between the two is not limited to adhesive or screw connection; the shape of the T-shaped guide block 5 is adapted to the T-shaped track groove 41, and the T-shaped guide block 5 can slide in the T-shaped track groove 41.

[0046] In this optional embodiment, when installing the cooling fan 3, first align the T-shaped guide block 5 connected to the side end face of the mounting bracket 31 with one end opening of the T-shaped track slot 41 of the mounting post 4, and then slide the T-shaped guide block 5 into the T-shaped track slot 41 until the T-shaped guide block 5 can no longer move. At this point, the installation of the cooling fan 3 can be completed.

[0047] Furthermore, T-shaped guide blocks 5 are provided on opposite sides of the mounting bracket 31; the two T-shaped guide blocks 5 are respectively set to correspond to the two mounting posts 4.

[0048] Specifically, such as Figure 5 , 6 As shown, there are two mounting posts 4, which are spaced apart on the door panel 2; T-shaped guide blocks 5 are provided on opposite sides of the mounting bracket 31, and the two T-shaped guide blocks 5 are slidably connected to the two mounting posts 4 respectively.

[0049] In this optional embodiment, the two opposite ends of the mounting bracket 31 are slidably connected to the two mounting posts 4 via T-shaped guide blocks 5. Therefore, after the cooling fan 3 is installed on the door panel 2, not only can the position of the mounting bracket 31 be restricted, but the forces on the opposite ends of the mounting bracket 31 can also be balanced.

[0050] Optionally, the first quick-release structure includes two connecting posts 6 spaced apart on the door panel 2; the two connecting posts 6 are respectively provided with a U-shaped groove structure 61 at one end facing each other, and the groove structure 61 is provided with an inlet at one end face of the connecting post 6 along its length; the second quick-release structure includes two connecting blocks 7 respectively provided at opposite ends of the mounting bracket 31; the two connecting blocks 7 are slidably connected to the two groove structures 61 respectively.

[0051] Specifically, such as Figure 7 , 8 As shown, two connecting columns 6 are vertically and spaced apart on the door panel 2. The connection between the door panel 2 and the connecting columns 6 includes, but is not limited to, welding or screw connection. The two connecting columns 6 are provided with a U-shaped groove structure 61 at their respective ends facing each other. The groove structure 61 has an inlet on the top surface of the connecting column 6. The mounting bracket 31 is provided with connecting blocks 7 at its opposite ends. The two connecting blocks 7 are slidably connected to the two groove structures 61 respectively.

[0052] In this optional embodiment, when installing the cooling fan 3, first align the connecting blocks 7 at both ends of the mounting bracket 31 with the inlet of one end of the groove structure 61 of the two mounting posts 4, and then slide the connecting blocks 7 into the groove structure 61 until the connecting blocks 7 can no longer move. At this point, the installation of the cooling fan 3 can be completed.

[0053] Optionally, the vent 21 includes a plurality of grid units 211, and the cooling fan 3 covers at least one grid unit 211.

[0054] Specifically, the number of grid cells 211 can be two, three, or four, etc., without limitation, depending on the actual needs. For example... Figure 2 As shown, there are four grid units 211. The four grid units 211 are rectangular and arranged in parallel, and the cooling fan 3 covers the four grid units 211.

[0055] In this optional embodiment, the design of multiple grid units 211 can effectively improve airflow resistance, thereby improving the heat dissipation effect of the inverter cabinet.

[0056] Optionally, the mounting bracket 31 is provided with a gripping structure 312.

[0057] Specifically, such as Figure 6 , 9 As shown, the gripping structure 312 is a through groove structure 61 provided on the upper part of the mounting bracket 31. The through groove structure 61 has openings on the top surface and the front surface of the mounting bracket 31, respectively. The shape of the opening can be square, round or other irregular shape, which is not limited here and depends on the actual needs.

[0058] In this optional embodiment, when it is necessary to disassemble the cooling fan 3, the operator can pass his palm through the through-slot structure 61 and hold it, and then pull the cooling fan 3 out of the door panel 2.

[0059] In other embodiments, the grip structure 312 may also be a handle provided on the mounting bracket 31, and the handle may be U-shaped or square-shaped.

[0060] This utility model provides a soft water production line, including a drive pump and a frequency converter cabinet as described above, wherein the drive pump is electrically connected to the frequency converter cabinet.

[0061] Specifically, the inverter cabinet also includes an inverter 8, which is located inside the cabinet body 1 and in the airflow path of the cooling fan 3. The drive pump is electrically connected to the inverter 8. Thus, when the inverter 8 is used in conjunction with the drive pump, variable frequency speed regulation of the drive pump can be achieved, thereby precisely controlling the flow and pressure of the drive pump. In other words, the inverter 8 can automatically adjust the speed of the drive pump according to the actual water demand to achieve energy saving and optimized operation.

[0062] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
