Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, and in particular to a dustproof control cabinet. Background Art

[0002] As a device for centralized control and protection of electrical equipment, the control cabinet can not only effectively organize and distribute various electrical components, but also provide a certain degree of electrical isolation and protection through internal structural design to ensure the stable operation of the entire electrical system. However, in actual use, since the staff needs to regularly inspect and maintain the control cabinet, foreign objects such as dust from the outside may enter the control cabinet during the process of opening the device. At the same time, heat dissipation and ventilation devices such as cooling fans will also become channels for dust to enter. Dust will gradually accumulate on the surface of electrical equipment, affecting the heat dissipation effect, and even causing equipment short circuit or damage, thereby affecting the normal operation of the control cabinet. Summary of the invention

[0003] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0004] The control cabinet needs to be inspected and maintained regularly during operation to ensure the normal operation of its internal electrical components. During this process, the opening and closing of the control cabinet becomes a potential risk point for external dust to enter the interior. Once dust enters the control cabinet, it will adhere to the surface of the electrical components, which will not only affect its heat dissipation performance, but may also cause equipment short circuit or damage, thus posing a threat to the stable operation of the entire electrical system.

[0005] Secondly, in order to cope with the heat generated by the operation of electrical components inside the control cabinet, ventilation devices such as cooling fans are usually installed to enhance the heat dissipation effect. However, while these ventilation devices promote air flow, they also become a "gateway" for dust to enter the control cabinet. After dust enters the control cabinet through the ventilation device, it will be deposited on the electrical components, reducing the heat dissipation performance of the equipment, which may cause the electrical components to overheat and even cause equipment damage.

[0006] To this end, an embodiment of the present invention proposes a dustproof control cabinet, which includes a cabinet body, a door body and a dustproof component, the cabinet body includes a frame and multiple side panels, the multiple side panels are arranged around the frame to define a accommodating cavity, the door body is rotatably connected to the cabinet body to open and close the accommodating cavity, and the side panels are provided with ventilation holes; the dustproof component includes a filter frame and a dustproof plate, the filter frame is arranged on the side panel, and the filter frame is located on the side of the side panel facing the accommodating cavity; the dustproof plate is arranged at the opening of the accommodating cavity, and the dustproof plate is provided with an observation window.

[0007] In summary, the dustproof control cabinet provided in the embodiment of the present invention achieves all-round protection for electrical components in the accommodating cavity by cleverly combining the design of the filter frame and the dustproof plate. It not only effectively isolates the invasion of pollutants such as dust, but also provides a convenient observation and maintenance method, providing a solid guarantee for the stable operation of electrical equipment.

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 4As shown, an embodiment of the present invention provides a dustproof control cabinet 100, which includes a cabinet 10, a door 20 and a dustproof assembly 30. The cabinet 10 includes a frame 11 and a plurality of side panels 12. The plurality of side panels 12 are arranged around the frame 11 to define a receiving cavity. The door 20 and the cabinet 10 are rotatably connected to open and close the receiving cavity. The receiving cavity is used to place electrical components. The side panel 12 is provided with a vent 121, which is used to allow airflow to enter the receiving cavity. The dustproof assembly 30 includes a filter frame 31 and a dustproof plate 32. The filter frame 31 is arranged on the side panel 12, and the filter frame 31 is located on the side of the side panel 12 facing the receiving cavity. The dustproof plate 32 is arranged at the opening 13 of the receiving cavity. The dustproof plate 32 is provided with an observation window 321, which can not only facilitate users to observe the operating conditions of the electrical components in the receiving cavity, but also prevent foreign matter such as dust from entering the receiving cavity when the door 20 is opened.

[0031] Specifically, the cabinet 10, as the main structure of the entire dustproof control cabinet 100, is composed of a frame 11 and a plurality of side panels 12, which not only enhances the overall structural strength, but also provides necessary protection for its internal components. The filter frame 31 is arranged on the side of the side panel 12 facing the accommodating cavity, so that when the airflow enters the accommodating cavity through the vent 121, it must pass through the filter frame 31 layer by layer, effectively blocking the invasion of foreign matter such as dust, and ensuring the cleanliness of the electrical components in the accommodating cavity. The dustproof plate 32 is arranged at the opening 13 of the accommodating cavity, that is, the inner side of the door body 20. When the door body 20 is in an open state, the dustproof plate 32 can effectively prevent external dust and debris from entering the accommodating cavity, further improving the dustproof performance of the control cabinet. In addition, an observation window 321 is provided on the dustproof plate 32, so that the user can observe the operating status of the electrical components in the accommodating cavity by opening the door body 20, which greatly improves the convenience and safety of operation.

[0032] In summary, the dustproof control cabinet 100 provided in the embodiment of the present invention achieves all-round protection for the electrical components in the accommodating cavity by cleverly combining the design of the filter frame 31 and the dustproof plate 32. It not only effectively isolates the invasion of pollutants such as dust, but also provides a convenient observation and maintenance method, providing a solid guarantee for the stable operation of electrical equipment.

[0033] like Figure 2 As shown, in some embodiments, a plurality of observation windows 321 are provided, and the plurality of observation windows 321 are distributed in an array. This not only improves the breadth and depth of observation, so that the operator can observe the working state of each electrical component in the accommodating cavity more comprehensively and meticulously, but also enhances the overall structural strength of the dustproof plate 32 to a certain extent, making it more durable while maintaining its lightness, and better able to resist external impact and wear.

[0034] In addition, the position and size of the observation window 321 can be set as needed to ensure that each observation window 321 can provide an optimal field of view, while avoiding the problem of reduced dustproof performance due to too many or too large observation windows 321. This design that takes into account both practicality and aesthetics allows the dustproof control cabinet 100 to ensure the safe operation of electrical components while also showing an excellent sense of industrial design.

[0035] In some embodiments, the dustproof plate 32 is provided with a plurality of dustproof nets 322, and the dustproof nets 322 and the observation windows 321 are staggered in the height direction of the cabinet 10, so that the dustproof plate 32 can maintain high dustproof performance while ensuring that the operator can obtain a good observation field of view at different heights without frequently adjusting the observation angle or position. In other words, the staggered arrangement of the dustproof nets 322 and the observation windows 321 can ensure the effective circulation of the air in the accommodating cavity, avoiding the problem of poor air circulation caused by overly strict dustproof measures. This design that takes into account both dustproof effect and air circulation allows the dustproof control cabinet 100 to maintain a clean internal environment while ensuring normal heat dissipation of electrical components, thereby extending the service life of the equipment.

[0036] Furthermore, a handle groove 323 is provided on the dustproof plate 32, so that the operator can easily and quickly open or close the dustproof plate 32 when needed, so as to observe, maintain or inspect the electrical components. The shape and size of the handle groove 323 can be set as needed, which can ensure that the operator's fingers can be easily inserted and firmly held, and can avoid accidental injuries caused by finger slippage or collision during operation. In this embodiment, two handle grooves 323 are provided, and the two handle grooves 323 are oppositely arranged on both sides of the dustproof plate 32.

[0037] like Figure 3 As shown, in some embodiments, the dustproof control cabinet 100 also includes a connecting component 40, the connecting component 40 includes a movable plunger 42 and an elastic member 41, the dustproof plate 32 has a slide groove 324, the movable plunger 42 is movably arranged in the slide groove 324, one end of the elastic member 41 is connected to the dustproof plate 32, and the other end of the elastic member 41 is connected to the movable plunger 42, and a positioning hole matching the movable plunger 42 is provided on the cabinet body 10.

[0038] Specifically, one end of the elastic member 41 is firmly connected to the dustproof plate 32, and the other end is closely connected to the movable plunger 42, which not only ensures the stability and controllability of the movable plunger 42 during the movement, but also through the elastic force of the elastic member 41, the movable plunger 42 can automatically pop into and be fixed in the positioning hole on the cabinet 10 when it reaches the specified position, thereby realizing a quick and stable connection between the dustproof plate 32 and the cabinet 10. In addition, the positioning hole corresponds to the slide groove 324 one by one, and the positioning hole is used to accommodate the movable plunger 42, ensuring that the movable plunger 42 can accurately find and pop into it during the movement, thereby avoiding the problems of unstable installation or difficult removal of the dustproof plate 32 due to inaccurate positioning. This design not only improves the installation efficiency of the dustproof control cabinet 100, but also ensures that the dustproof plate 32 can always remain stable and reliable during use.

[0039] Furthermore, the elastic member 41 is configured as a spring, and the movable plunger 42 includes a connecting column 421 and a ball head 422 connected to each other, and the connecting column 421 is inserted into the spring. One end of the spring is tightly connected to the dustproof plate 32, and the other end is sleeved with the connecting column 421 in the movable plunger 42, so that when the movable plunger 42 moves in the slide groove 324, the spring can provide the necessary elastic force and guiding effect, ensuring that the movable plunger 42 can move steadily and smoothly, and can automatically pop into the positioning hole on the cabinet 10 when reaching the designated position. The shape of the ball head 422 matches the shape of the positioning hole, and the ball head 422 can extend into the positioning hole.

[0040] Furthermore, the connection components 40 are arranged in multiple groups, and the multiple groups of connection components 40 are symmetrically arranged on both sides of the dustproof plate 32, and the positioning holes are arranged in a one-to-one correspondence with the connection components 40. Not only is the connection strength between the dustproof plate 32 and the cabinet 10 enhanced, but also the balance and stability of the dustproof plate 32 during installation and removal are ensured, and deformation or damage caused by uneven force is avoided. At the same time, in order to match the multiple groups of connection components 40, a plurality of positioning holes are also specially provided on the cabinet 10. These positioning holes correspond to the connection components 40 one by one, ensuring that each movable plunger 42 can accurately find and pop into its corresponding positioning hole. This design not only improves the installation accuracy and efficiency of the dustproof control cabinet 100, but also ensures that the dustproof plate 32 can always maintain a stable and reliable state during use, effectively preventing problems such as dust intrusion or damage to electrical components caused by loose connections.

[0041] like Figure 4As shown, in some embodiments, the dustproof component 30 also includes a dust box 33, a mounting groove 311 is provided at the bottom of the filter frame 31, the dust box 33 is arranged in the mounting groove 311, and an electrostatic plate 34 is provided in the dust box 33, so that dust and other foreign matter in the filter frame 31 are deposited in the dust box 33, and dust and other foreign matter in the filter frame 31 can be effectively collected.

[0042] That is to say, the dust box 33 is placed at the bottom of the filter frame 31, and the principle of gravity can be used to make the filter frame 31 intercept and absorb dust and other tiny particles, and these foreign matter can be naturally deposited in the dust box 33 below. In order to ensure that the dust box 33 can be stably and conveniently installed at the bottom of the filter frame 31, the bottom of the filter frame 31 is specially designed with a mounting groove 311 that matches the shape of the dust box 33. This design not only ensures a tight fit between the dust box 33 and the filter frame 31, effectively preventing dust leakage, but also improves the overall structural strength of the dustproof assembly 30.

[0043] In addition, the electrostatic plate 34 can use the principle of electrostatic adsorption to capture and fix tiny particles such as dust. Its surface is covered with an electrostatic layer, which can efficiently adsorb and fix dust particles that enter the dust box 33 through the filter frame 31. It not only greatly improves the dust removal efficiency of the dust box 33 and ensures the continuous and efficient operation of the filter frame 31, but also effectively extends the service life of the filter frame 31, because the electrostatic plate 34 shares part of the filtering work, reducing the filtering burden of the filter frame 31.

[0044] Furthermore, the filter frame 31 is provided with a through hole connected to the mounting groove 311, and the dust box 33 is slidably arranged in the mounting groove 311 through the through hole, which not only simplifies the installation process of the dust box 33, allowing the operator to easily push or pull the dust box 33 into or out of the mounting groove 311, but also improves the stability and accuracy of the dust box 33 during the installation process, and avoids problems such as dust leakage or structural damage caused by improper installation.

[0045] Furthermore, the side panel 12 is detachably connected to the frame 11, and the filter frame 31 has a lower opening 312 and a side opening 313. The side opening 313 of the filter frame 31 is arranged toward the side panel 12, and the lower opening 312 of the filter frame 31 is arranged toward the dust box 33. Among them, the design of the lower opening 312 allows dust and other foreign matter accumulated in the filter frame 31 to fall smoothly into the dust box 33 below, thereby ensuring the continuous and efficient operation of the dustproof component 30. The side opening 313 is arranged toward the side panel 12, which can conveniently guide the airflow into the filter frame 31 to achieve an efficient filtering function. This design not only improves the filtering efficiency of the dustproof component 30, but also ensures the smooth circulation of the airflow, providing a strong guarantee for the stable operation of the electrical equipment.

[0046] Furthermore, the side panel 12 is firmly and flexibly connected to the frame 11 by means of a connection member such as a bolt or a locking mechanism. This connection method not only ensures the stability of the side panel 12 in daily work, but also enables the operator to easily remove the side panel 12 from the frame 11 when necessary, thereby conveniently performing deep cleaning, detailed maintenance, or component replacement operations on the inside of the dustproof assembly 30. In this embodiment, the side panel 12 is fixed to the frame 11 by screws.

[0047] like Figure 4 As shown, in some embodiments, the dustproof control cabinet 100 further includes a fan 50, which is disposed at the vent 121 of the side panel 12, and the fan 50 and the vent 121 are disposed one-to-one. In this embodiment, two vents 121 are provided, and correspondingly, two fans 50 are provided.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the dust control cabinet 100 further includes a base frame 60, the base frame 60 includes a frame body 61 and pillars 62 located at the four corners of the bottom of the frame body 61, the cabinet body 10 is arranged above the frame body 61, and the frame body 61 is provided with a plurality of ventilation holes 611. In other words, the base frame 60 can enable the dust control cabinet 100 to be stably raised, so that a certain space is formed between the bottom of the cabinet body 10 and the ground, providing more favorable conditions for ventilation and heat dissipation, thereby facilitating the maintenance and cooling operation of the bottom of the cabinet body 10. During the long-term operation of the electrical equipment, a large amount of heat will be generated inside the cabinet body 10, and the ventilation holes 611 can accelerate the air flow at the bottom of the cabinet body 10, so that the heat emitted by the cabinet body 10 is taken away by the air flow, thereby ensuring the stable operation of the electrical equipment.

[0049] like Figure 1 As shown, in some embodiments, a handle 21 is provided on the door body 20. When in use, the staff can open and close the door body 20 by pulling the handle 21 on the door body 20. In addition, a rectangular groove is provided at the center of the front of the door body 20, and a display screen 22 is provided on the inner wall of the rectangular groove. Through the arrangement of the door body 20 and the display screen 22, when in use, some data inside the device can be displayed on the display screen 22 to help the staff understand the status of the device.

[0050] During the use of the dustproof control cabinet provided by the embodiment of the present invention, when the weather is hot or the temperature of the equipment inside the device is high, the staff needs to connect the device to an external power source and start the fan 50, so that the fan 50 cooperates with the vent 121 to accelerate the flow of air inside the device and cool down the equipment in the device. The air entering the device will be filtered by the filter frame 31, leaving the dust in the filter frame 31. After a long period of accumulation, the dust will fall into the dust box 33 at the bottom of the filter frame 31 and be adsorbed by the electrostatic plate 34 in the dust box 33. The staff can pull the dust box 33 out to centrally process the dust in the dust box 33.

[0051] In addition, when the staff needs to check the equipment in the device, they can first open the door 20, and the equipment in the device will correspond to the observation window 321 one by one. The staff can first understand the status of the equipment in the device according to the observation window 321; if it is necessary to operate the equipment in the device, the dustproof plate 32 can be pulled out; after maintenance, the movable plungers 42 on both sides of the dustproof plate 32 are aligned with the positioning holes on the inner wall of the cabinet 10, and the rebound ball head 422 of the elastic member 41 bounces into the positioning hole to achieve the installation of the dustproof plate 32.
