Description

Technical Field

[0001] The present invention relates to the technical field of ventilation and heat dissipation of control cabinets, and particularly to an intelligent industrial PLC control cabinet device. Background Art

[0002] In an industrial automation control system, as the core control unit, the working reliability of the electrical components inside the PLC cabinet (including CPU modules, I / O modules, relays, power supplies, etc.) directly determines the stability of the entire system. In extremely low-temperature environments (such as industrial sites in cold regions, cold storages, polar equipment, etc.), the lower limit of the working temperature of the electrical components in a conventional PLC cabinet is -20°C to -25°C, and its low-temperature tolerance ability faces severe challenges.

[0003] Publication No. CN117545210B discloses a ventilation and heat dissipation device for a PLC control cabinet used in an industrial control system, including a cabinet body and a ventilation component. Openings are provided on opposite sides of the cabinet body, and slot holes are provided on the other two sides of the cabinet body. A door body is fitted and installed on the opening, a base is fixed at the bottom of the cabinet body, and the ventilation component includes a cover body, a fan component, and a channel. The cover body is fitted and installed in the slot hole, the two cover bodies are communicated through the channel, and a fan component is fitted and installed at the port of the channel. In the present invention, the sleeve is hermetically connected to the channel, preventing air passing through the long and narrow channel from entering the interior of the cabinet body, and preventing external air from carrying dust into the interior of the cabinet body, thereby effectively reducing the problem of dust accumulation inside the cabinet body. At the same time, it also prevents external humid air from entering the interior of the cabinet body, effectively solving the problem of short circuits of equipment caused by humid air and accumulated dust.

[0004] During the actual use of the above device, in an extremely low-temperature environment, it cannot play a heat preservation role for the electrical components inside the cabinet, thus affecting the normal operation of the electrical components. Summary of the Invention

[0005] By providing an intelligent industrial PLC control cabinet device, the present application solves the technical problem in the prior art that in an extremely low-temperature environment, it cannot play a heat preservation role for the electrical components inside the cabinet, thus affecting the normal operation of the electrical components. By squeezing the film with a moving roller, the two films are tightly attached to each other and block the ventilation openings, playing a heat preservation role for the cabinet box, and preventing the normal operation of the electrical components inside the cabinet box from being affected by the extremely low-temperature environment.

[0006] This application provides an intelligent industrial PLC control cabinet device. The cabinet further includes a set of heat dissipation components. The heat dissipation components include symmetrically arranged heat dissipation frames. Between the two heat dissipation frames, there are symmetrically arranged air guiding members, pull ropes, and films. A ventilation opening is formed between the two air guiding members. A moving roller is provided inside the air guiding member, and a clamping block is fixed on the pull rope. By pulling the pull rope to drive the clamping block to squeeze the film, the two films move closer to each other, closely adhere to and block the ventilation opening, reducing heat dissipation and playing a heat preservation role for the electrical components in the cabinet. One side of the cabinet is hinged with a cabinet door. A temperature detector is also arranged inside the cabinet. Each set of heat dissipation components is arranged from top to bottom on both sides of the cabinet for dissipating heat from different areas inside the cabinet.

[0007] The two heat dissipation frames are symmetrically fixed on the side of the cabinet and are provided with channels communicating with the ventilation opening. One end of the heat dissipation frame is provided with a heat dissipation member. The upper end of the heat dissipation frame is fixed with an acting plate, and a circular groove is opened at the bottom of the acting plate. The heat dissipation component further includes a fixed shaft. One end of the fixed shaft is fixed in the circular groove of the acting plate, and the other end is fixed at the bottom inside the heat dissipation frame. A support plate is sleeved inside the fixed shaft and is clamped at the bottom inside the heat dissipation frame. The fixed shaft is rotatably connected with a rotating shaft with blades. The bottom of the rotating shaft is rotatably connected inside the support plate through a bearing, and the rotation of the rotating shaft cannot drive the support plate to rotate. The rotating shaft can slide up and down on the fixed shaft. An iron block is fixed at the upper end of the rotating shaft. An electromagnet is fixed in the circular groove of the acting plate. The electromagnet can magnetically attract the iron block to move the rotating shaft upward and drive the support plate upward. Both ends of the air guiding member are respectively fixed on the heat dissipation frames in the corresponding directions. A first inner cavity is opened inside the air guiding member. A curved frame is fixed in the middle of the air guiding member. A film is also fixed on the curved frame and is close to the ventilation opening. An extrusion cavity is formed by the curved frame and the film. One end of the pull rope is fixed at one end of the air guiding member, and the other end respectively passes through the other end of the air guiding member and the curved frame and is fixed with the support plate. A guiding hook for limiting the pull rope is arranged inside the air guiding member. An inner through groove for the clamping block to pass through is opened at one end of the curved frame. By the upward movement of the support plate to pull the pull rope to pass through the inner through groove to squeeze the moving roller, the moving roller squeezes the film, making the two films closely adhere to each other. A moving cavity is opened at the middle bottom surface of the first inner cavity. A spring is fixed at one end inside the moving cavity, and the other end of the spring is fixed with a moving block. A moving roller is arranged at the upper end of the moving block and is inside the extrusion cavity. A guiding rod is arranged at the upper end of the moving roller, and a guiding groove for limiting the guiding rod is opened at the upper end of the air guiding member. Due to the elastic force of the spring, the moving roller can return to its original position when not being squeezed.

[0008] Further, a temperature detector is provided at a position corresponding to each set of heat dissipation components in the cabinet; an outer groove is equidistantly formed on the outer cross-section of the moving roller from top to bottom, and a magnet block is fixed in the outer groove; an embedding block is fixed in the film, and a magnetic material is installed in the embedding block; a rotating motor is fixed at the upper end of the moving block, and the bottom of the moving roller is rotatably connected to the outer cross-section of the moving block through a bearing; the output end of the rotating motor is connected to the bottom of the moving roller.

[0009] Further, the magnet blocks are divided into a first magnet, a second magnet, and a third magnet with different lengths; the length ratio of the first magnet to the second magnet is 3:2, and the length ratio of the first magnet to the third magnet is 3:1.

[0010] Further, a plurality of strip-shaped capsules are arranged in the embedding block, and iron powder is filled in the strip-shaped capsules.

[0017] Embodiment 1: As Figures 1 to 6As shown in the figure, an intelligent industrial PLC control cabinet device of the present application. The cabinet 100 further includes 3 groups of heat dissipation components 200. The heat dissipation component 200 includes symmetrically arranged heat dissipation frames 210. Between the two heat dissipation frames 210, a wind guiding member 220, a pulling rope 230, and a thin film 240 are symmetrically arranged; a ventilation opening is formed between the two wind guiding members 220; a moving roller 250 is arranged in the wind guiding member 220, and a clamping block 260 is fixed on the pulling rope 230; by pulling the pulling rope 230 to drive the clamping block 260 to squeeze the thin film 240, the two thin films 240 approach each other, tightly adhere to and block the ventilation opening, reducing heat dissipation and playing a heat preservation role for the electrical components in the cabinet 100; One side of the cabinet 100 is hinged with a cabinet door 110; a temperature detector 120 is also arranged in the cabinet 100; each group of heat dissipation components 200 is arranged on both sides of the cabinet 100 from top to bottom for dissipating heat from different areas in the cabinet 100.

[0018] The two heat dissipation frames 210 are symmetrically fixed on the side of the cabinet 100 and are provided with channels communicating with the ventilation opening; one end of the heat dissipation frame 210 is provided with a heat dissipation member 211; a function disk 212 is fixed at the upper end of the heat dissipation frame 210, and a circular groove is opened at the bottom of the function disk 212; the heat dissipation component 200 further includes a fixed shaft 213, one end of the fixed shaft 213 is fixed in the circular groove of the function disk 212, and the other end is fixed at the bottom in the heat dissipation frame 210; a support disk 214 is sleeved in the fixed shaft 213 and is clamped at the bottom in the heat dissipation frame 210; the fixed shaft 213 is rotatably connected with a rotating shaft 215 with blades; the bottom of the rotating shaft 215 is rotatably connected in the support disk 214 through a bearing, and the rotation of the rotating shaft 215 cannot drive the support disk 214 to rotate; the rotating shaft 215 can slide up and down on the fixed shaft 213; An iron block 216 is fixed at the upper end of the rotating shaft 215; an electromagnet 217 is fixed in the circular groove of the function disk 212; the electromagnet 217 can magnetically attract the iron block 216 to move the rotating shaft 215 upward and drive the support disk 214 to move upward; Both ends of the wind guiding member 220 are respectively fixed on the heat dissipation frames 210 in the corresponding directions; a first inner cavity 221 is opened in the wind guiding member 220; a curved frame 222 is fixed in the middle of the wind guiding member 220; a thin film 240 is also fixed on the curved frame 222 and is close to the ventilation opening; an extrusion cavity is formed by the curved frame 222 and the thin film 240; One end of the drawstring 230 is fixed to one end of the air guide member 220, and the other end passes through the other end of the air guide member 220 and the curved frame 222 respectively and is fixed to the support disk 214; a guiding hook for limiting the drawstring 230 is arranged inside the air guide member 220; an inner through groove for the clamping block 260 to pass through is formed at one end of the curved frame 222; when the support disk 214 moves upward to pull the drawstring 230 to pass through the inner through groove to squeeze the moving roller 250, the moving roller 250 squeezes the film 240, so that the two films 240 are closely attached to each other face to face; A moving cavity 223 is formed in the middle bottom surface of the first inner cavity 221, a spring 224 is fixed at one end inside the moving cavity 223, and a moving block 225 is fixed at the other end of the spring 224; a moving roller 250 is arranged at the upper end of the moving block 225, and the moving roller 250 is inside the extrusion cavity; a guiding rod is arranged at the upper end of the moving roller 250, and a guiding groove for limiting the guiding rod is formed at the upper end of the air guide member 220; due to the elastic force of the spring 224, the moving roller 250 can return to its original position when not being squeezed.

[0019] Specific implementation: When the temperature detector 120 in the cabinet 100 detects that the temperature in the cabinet reaches -25°C, the upper and lower groups of the three groups of heat dissipation components 200 start the electromagnet 217 to magnetically attract the iron block 216, so that the rotating shaft 215 moves upward. The upward movement of the rotating shaft 215 drives the support disk 214 to move upward. The upward movement of the support disk 214 pulls the drawstring 230. The drawstring 230 is driven by the tension to drive the clamping block 260 to move into the extrusion cavity and squeeze the moving roller 250. The moving roller 250 squeezes the film 240 towards the ventilation opening, so that the two films 240 are closely attached to each other face to face and block the ventilation opening; thus, the heat dissipation path in the cabinet 100 can only dissipate heat through the ventilation opening of the middle heat dissipation component 200, and the heat dissipation speed slows down, so as to play a heat preservation role; when the temperature in the cabinet 100 reaches -10°C, the electromagnet 217 is turned off, the rotating shaft 215 returns to its original position, the drawstring 230 is no longer pulled by the support disk 214 and returns to its original position, the clamping block 260 no longer squeezes the moving roller 250, and the moving roller 250 and the moving block 225 return to their original positions due to the elastic force of the spring 224, and the film 240 is no longer closely attached and a ventilation opening is formed.

[0020] Beneficial effects: By squeezing the film 240 with the moving roller 250, the two films 240 are closely attached to each other face to face and block the ventilation opening, playing a heat preservation role for the inside of the cabinet 100 and preventing the normal operation of the electrical components inside the cabinet 100 from being affected by extreme low temperature environments.

[0021] Embodiment 2: When the upper and lower groups of heat dissipation components 200 block the ventilation opening, when some electrical components in the cabinet 100 age, the heat generated may accumulate at the ventilation opening of the middle heat dissipation component 200, causing the electrical components near the middle to heat up and affecting their performance; in view of the above technical problems, the present application proposes the following technical solutions, specifically: AsFigure 7 and Figure 8 As shown, a temperature detector 120 is provided at the position corresponding to each group of heat dissipation components 200 in the cabinet 100; three outer grooves 251 are equidistantly formed on the outer cross-section of the moving roller 250 from top to bottom, and magnet blocks 252 are fixed in the outer grooves 251; an embedding block 253 is fixed in the film 240, and the embedding block 253 is filled with a magnetic material; a rotating motor 2251 is fixed at the upper end of the moving block 225, and the bottom of the moving roller 250 is rotatably connected to the outer cross-section of the moving block 225 through a bearing; the output end of the rotating motor 2251 is connected to the bottom of the moving roller 250; the magnet block 252 magnetically attracts the embedding block 253, and the embedding block 253 moves towards the magnet block 252 to drive the film 240 to form a concave shape, thereby forming a heat dissipation hole.

[0022] Specific implementation: When the temperature detector 120 in the middle detects that the temperature around the middle group of heat dissipation components 200 rises, and the temperature around the upper or lower group of heat dissipation components 200 also rises, start the rotating motor 2251 of the corresponding group of heat dissipation components 200 with the increased surrounding temperature, so that the moving roller 250 rotates to make the magnet block 252 magnetically attract the embedding block 253 to drive the film 240 to form a concave shape, forming a heat dissipation hole, and dissipating heat evenly.

[0023] One or more technical solutions provided in this application have at least the following technical effects or advantages: By rotating the moving roller 250 to make the magnet block 252 magnetically attract the embedding block 253 to form a heat dissipation hole, the heat dissipated by the aging electrical components in different regions can be evenly dissipated through the corresponding heat dissipation holes, preventing heat from accumulating in a certain place and affecting the operation of normal electrical components, and the heat dissipation holes formed by the film 240 in the three groups of heat dissipation components 200 can effectively dissipate the heat in the corresponding regions in a timely manner.

[0024] Embodiment 3: Since the number of heat dissipation holes opened in each group of heat dissipation components 200 is fixed and cannot cope with the heat of different temperatures; in response to the above technical problems, the following technical solutions are proposed in this application, specifically: As Figure 9 shown, the magnet block 252 is divided into a first magnet 2521, a second magnet 2522, and a third magnet 2523 with different lengths; the length ratio of the first magnet 2521 to the second magnet 2522 is 3:2, and the length ratio of the first magnet 2521 to the third magnet 2523 is 3:1; rotating the angle of the moving roller 250 can control the number of heat dissipation holes formed by the first magnet 2521, the second magnet 2522, and the third magnet 2523 with different lengths magnetically attracting the embedding block 253 to drive the film 240, so as to cope with the heat of different temperatures and dissipate heat.

[0025] Specific implementation: By rotating the moving roller 250, when one-third of the length of the first magnet 2521 corresponds to the embedding block 253, the embedding block 253 corresponding to the first magnet 2521 drives the film 240 to concave to form heat dissipation holes; when two-thirds of the length of the first magnet 2521 corresponds to the embedding block 253, the embedding blocks 253 corresponding to the second magnet 2522 and the first magnet 2521 drive the film 240 to concave to form heat dissipation holes; when the full length of the first magnet 2521 corresponds to the embedding block 253, the embedding blocks 253 corresponding to the first magnet 2521, the second magnet 2522, and the third magnet 2523 drive the film 240 to concave to form heat dissipation holes.

[0027] Embodiment 4: In order to accurately cope with the heat of different temperatures; in response to the above technical problems, this application proposes the following technical solutions, specifically: As Figures 10 to 12 shown, a plurality of strip-shaped capsules 254 are arranged in the embedding block 253, and iron powder is contained in the strip-shaped capsules 254; by the magnetic attraction of the first magnet 2521, the second magnet 2522, and the third magnet 2523 on the iron powder in the embedding block 253, the film 240 forms a corrugated film wall, improving the heat dissipation speed; by the magnitude of the rotation angle of the first magnet 2521, the second magnet 2522, and the third magnet 2523, the amount of magnetism on the iron powder can be adjusted, so that the iron powder in different regions moves towards the direction of the first magnet 2521, the second magnet 2522, and the third magnet 2523, thereby making the film 240 form a curved shape and improving the heat dissipation speed.

[0028] One or more technical solutions provided in this application have at least the following technical effects or advantages: By the magnitude of the rotation angle of the first magnet 2521, the second magnet 2522, and the third magnet 2523, the amount of magnetic action on the iron powder in the embedding block 253 can be adjusted, so that the iron powder in different regions moves towards the direction of the first magnet 2521, the second magnet 2522, and the third magnet 2523, thereby making the film 240 form a curved film wall and improving the heat dissipation speed; through the fluidity of the iron powder in the strip-shaped capsules 254, the bending radian of the film 240 can be dynamically adjusted with the change of the magnetic field, realizing fine adjustment of the heat dissipation hole size and the air flow path, so as to accurately match the heat dissipation requirements at different temperatures.
