Abstract
Description
Technical Field
[0001] This utility model relates to the field of frequency converter technology, specifically to an adaptive protective housing based on the frequency converter structure. Background Technology
[0002] A frequency converter is a power control device used to control the speed and torque of an AC motor. By changing the power supply frequency and voltage, it achieves precise control of the motor's operating status and has advantages such as high efficiency and energy saving, wide speed range, and smooth start-up.
[0003] To ensure the normal operation of the frequency converter, an enclosure is used to protect it. However, when it is impacted, the enclosure will deform, causing damage to the frequency converter and rendering it unusable. At the same time, when the frequency converter is used in different environments, dust and liquids from the outside environment can enter the frequency converter when the external environment is harsh, causing damage and rendering it unusable. Therefore, we propose an adaptive protective enclosure based on the frequency converter structure. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an adaptive protective housing based on the inverter structure. This solves the problem that when the inverter is subjected to a collision, the housing will deform directly, causing damage to the inverter and rendering it unusable. Additionally, when the inverter is used in different environments, dust and liquids from the outside environment can enter the inverter in harsh conditions, causing damage and rendering it unusable.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive protective housing based on a frequency converter structure, comprising a housing, in which the frequency converter is installed, a control panel on the front of the housing, the control panel being electrically connected to the frequency converter in the housing, a front protection unit on the front of the housing for protecting the front of the housing, side protection units on both sides of the front protection unit for protecting the sides of the housing from impact, the front protection unit comprising a protective frame and a limiting component, the protective frame being slidably connected to the periphery of the housing, heat dissipation holes on both sides of the housing, the protective frame being used to cover the heat dissipation holes, and the limiting component being disposed on the top end face of the protective frame for fixing the position of the protective frame relative to the housing.
[0006] Preferably, the limiting component includes:
[0007] A threaded rod is fixedly connected to the top end face of the protective frame;
[0008] A contact seat is fitted onto the outer peripheral wall of the threaded rod, and the contact seat is in contact with the top end face of the housing;
[0009] A spring is sleeved on the outer peripheral wall of a threaded rod, one end of which is fixedly connected to a contact seat. The spring is used to push the contact seat to contact and compress the outer shell.

[0015] This utility model discloses an adaptive protective housing based on a frequency converter structure, which has the following beneficial effects:
[0016] This adaptive protective enclosure based on the inverter structure can adjust the protective frame to move when the inverter inside the enclosure needs to dissipate heat, so that the protective frame does not block the heat dissipation holes on both sides of the enclosure, thus ensuring the heat dissipation effect of the inverter. When the inverter is in a harsh external environment, the protective frame can be adjusted to block the heat dissipation holes on both sides of the enclosure, preventing external dust or liquids from entering the enclosure and damaging the inverter.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] This application provides an adaptive protective housing based on the inverter structure, which solves the problems that when the inverter is hit, the housing 1 will deform directly, causing damage to the inverter and rendering it unusable. It also addresses the issue that when the inverter is used in different environments, dust and liquids can enter the inverter in harsh environments, causing further damage and rendering it unusable. The solution is to adjust the protective frame 31 to ensure that it does not block the ventilation holes on both sides of the housing 1 when the inverter inside the housing 1 needs heat dissipation, thus guaranteeing the inverter's heat dissipation effect. Conversely, when the inverter is in a harsh environment, the protective frame 31 can be adjusted to block the ventilation holes on both sides of the housing 1, preventing dust or liquids from entering the housing 1 and damaging the inverter.
[0025] When the protective frame 31 is impacted by the outside, it is pushed and slides along the outer shell 1. Under the action of the protective frame 31, the front of the outer shell 1 and the control panel 2 are protected and adaptively protected. When the protective frame 31 slides and collides with the outer shell 1, it cannot move. Under the action of the protective frame 31, the outer shell 1 is protected and continuous impact is prevented from colliding with the control panel 2 and the outer shell 1.
[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] This utility model discloses an adaptive protective housing based on a frequency converter structure.
[0028] Example 1:
[0029] According to the appendix Figure 1-3 As shown, the device includes a housing 1, in which a frequency converter is installed. A control panel 2 is provided on the front of the housing 1, and the control panel 2 is electrically connected to the frequency converter in the housing 1. A front protection unit 3 is provided on the front of the housing 1 to protect the front of the housing 1. Side protection units 4 are provided on both sides of the front protection unit 3 to protect the sides of the housing 1 from impact. The front protection unit 3 includes a protective frame 31 and a limiting component 32. The protective frame 31 is slidably connected to the peripheral wall of the housing 1. Heat dissipation holes are provided on both sides of the housing 1, and the protective frame 31 is used to cover the heat dissipation holes. The limiting component 32 is provided on the top end face of the protective frame 31 and is used to fix the position of the protective frame 31 and the housing 1.
[0030] When the inverter inside the housing 1 needs to dissipate heat, the protective frame 31 is moved by adjustment so that the protective frame 31 does not block the heat dissipation holes on both sides of the housing 1, thus ensuring the heat dissipation effect of the inverter. When the inverter is in a harsh external environment, the protective frame 31 is adjusted to block the heat dissipation holes on both sides of the housing 1 to prevent external dust or liquids from entering the housing 1 and damaging the inverter.
[0031] Limiting component 32 includes:
[0032] Threaded rod 321 is fixedly connected to the top end face of protective frame 31;
[0033] The contact seat 322 is sleeved on the outer peripheral wall of the threaded rod 321, and the contact seat 322 is in contact with the top end face of the housing 1;
[0034] Spring 323 is sleeved on the outer peripheral wall of threaded rod 321. One end of spring 323 is fixedly connected to contact seat 322. Spring 323 is used to push contact seat 322 to contact and squeeze the outer shell 1.
[0035] The outer peripheral wall of the threaded rod 321 is threaded with a nut seat 324, and the bottom end face of the nut seat 324 contacts the other end of the spring 323.
[0036] By rotating the nut seat 324, the nut seat 324 compresses the spring 323. At this time, the spring 323 pushes the contact seat 322 to compress the outer shell 1. When the protective frame 31 is impacted by the outside, the protective frame 31 is pushed and slides along the outer shell 1. Under the action of the protective frame 31, the front of the outer shell 1 and the control panel 2 are protected, providing adaptive protection.
[0037] As the protective frame 31 moves, the contact seat 322 moves along with the threaded rod 321. At this time, the contact seat 322 contacts the outer shell 1, limiting the movement of the protective frame 31 and generating a reverse thrust against external impacts, thus protecting the outer shell 1.
[0038] When the protective frame 31 slides and impacts the outer shell 1, the protective frame 31 cannot move. Under the action of the protective frame 31, the outer shell 1 is protected, and continuous impacts are prevented from causing collisions between the control panel 2 and the outer shell 1.
[0039] Example 2:
[0040] According to the appendix Figure 1-3 As shown, the device includes a housing 1, in which a frequency converter is installed. A control panel 2 is provided on the front of the housing 1, and the control panel 2 is electrically connected to the frequency converter in the housing 1. A front protection unit 3 is provided on the front of the housing 1 to protect the front of the housing 1. Side protection units 4 are provided on both sides of the front protection unit 3 to protect the sides of the housing 1 from impact. The front protection unit 3 includes a protective frame 31 and a limiting component 32. The protective frame 31 is slidably connected to the peripheral wall of the housing 1. Heat dissipation holes are provided on both sides of the housing 1, and the protective frame 31 is used to cover the heat dissipation holes. The limiting component 32 is provided on the top end face of the protective frame 31 and is used to fix the position of the protective frame 31 and the housing 1.
[0041] The side protection unit 4 includes a side protection plate 41, and upper and lower protection plates 43 are fixedly connected to both ends of the side protection plate 41.
[0042] The side guard plate 41 is located on the side of the guard frame 31, and the two upper and lower guard plates 43 are located at the upper and lower ends of the guard frame 31, respectively.
[0043] The side guard plate 41 protects the side of the protective frame 31, and the two upper and lower guard plates 43 protect the upper and lower ends of the protective frame 31. When the side guard plate 41 is impacted, it protects the side of the protective frame 31 and thus the side of the outer shell 1. When the upper and lower guard plates 43 are impacted, the side guard plate 41 supports them to prevent damage to the outer shell 1.
[0044] Guide rods 42 are fixedly connected to both sides of the protective frame 31, and the side protective plate 41 is slidably connected to the outer peripheral wall of the guide rods 42.
[0045] The outer peripheral wall of the guide rod 42 is provided with mounting bolts, and the side protective plate 41 is fixedly connected to the guide rod 42 by the mounting bolts.
[0046] When the side guard plate 41 is damaged, it is convenient to replace the side guard plate 41 to ensure continued protection of the guard frame 31.
