Description

Technical Field

[0001] This invention relates to a control cabinet, specifically an electrical heat dissipation control cabinet based on PLC control, belonging to the technical field of automated electrical control equipment. Background Technology

[0002] In general, PLC control is a commonly used electrical control system in automatic control systems, with wide applications in various control scenarios. PLC control devices can realize data acquisition, processing, storage, and output control, replacing traditional data acquisition cards, mechanical switches, and electromagnetic contactors. When constructing a PLC control system, various functional modules such as digital signal acquisition modules, analog signal acquisition modules, input / output modules, power supplies, and controllers can be combined according to control requirements to achieve complex control functions. Its control devices and modules are generally centrally installed in a control cabinet, and there are certain requirements for the operating environment and heat dissipation.

[0003] Currently, PLC electrical automation control devices on the market, while ensuring external airflow into the interior during heat dissipation, only electronic components near the air inlet receive good heat dissipation because the inlet position remains unchanged. Other electronic components within the enclosure experience poor heat dissipation, which may affect the efficiency and lifespan of these components over time. Furthermore, the lack of dust removal equipment or structures allows dust to fall into the device during prolonged use, further impacting its heat dissipation performance. In short, this process is often inconvenient.

[0004] Therefore, the key to solving the above technical problems lies in developing a safe, reliable, and efficient PLC-based electrical heat dissipation control cabinet. Summary of the Invention

[0096] In this invention, the electronic component 2 is installed inside the cabinet 1 after being connected by the side plates on both sides. The side plates on both sides are used to connect the electronic component 2 inside the cabinet.

[0097] Furthermore, such as Figure 5 As shown, the first heat dissipation component 5 includes:

[0098] Two first transmission rods 51 are arranged opposite to each other and are vertically rotatably connected to the opening inside the cabinet 1.

[0099] The first motor 52 is located on the top of the cabinet 1, and the output shaft of the first motor 52 is connected to the end of one of the first transmission rods 51.

[0100] The movable block 53 has two ends connected to the two first transmission rods 51 respectively.

[0101] Air guide block 54 is connected to the inner side of movable block 53;

[0102] Multiple sets of nozzles 55 are connected to the air guide block 54.

[0103] In this invention, connecting pipes are fixedly installed on the top of the movable block 53 and the bottom of the air pump 4, and the connecting pipe on the top of the movable block 53 is connected to the air guide block 54.

[0104] Specifically, both of the first transmission rods 51 are lead screws, or the one connected to the first motor 52 is a lead screw, and the other is a smooth guide rod;

[0105] A protective block 56 is also provided above the first motor 52;

[0106] A movable groove 531 is also provided below the movable block 53. A dust removal component 57 is slidably installed in the movable groove 531. The dust removal component 57 is connected to the air guide block 54 through an air supply hose. The dust removal component 57 is equipped with an air nozzle and a control valve.

[0107] In this invention, the protective block 56 can protect the first motor 52 while also achieving noise reduction and vibration damping. The dust removal component 57 consists of a telescopic tube, a jet nozzle connected to the end of the telescopic tube, and a control valve. The bottom of the movable block 53 is provided with a movable groove 531 for use with the dust removal component 57. The dust removal component 57 can blow air to a specific area. When the staff is installing and repairing electronic components 2 in the cabinet 1, they can move the dust removal component 57 to perform special dust removal treatment.

[0108] More specifically, the connection component 6 includes:

[0109] Connecting block 61 is connected through to the top plate of cabinet 1;

[0110] A scroll 62 is rotatably connected inside a connecting block 61.

[0111] A coil spring is disposed between the coil shaft 62 and the connecting block 61;

[0112] Gas delivery hose, the gas delivery hose is adapted to be connected to the reel 62;

[0113] One end of the air supply hose is connected to the air outlet of the air pump 4, and the other end of the air supply hose is connected to the air inlet of the air guide block 54.

[0114] In this invention, one end of the coil spring is fixed to the connecting block 61, and the other end is fixed to the roller 62; the coil spring provided between the roller 62 and the connecting block 61 enables the air delivery hose to automatically retract onto the roller 62; furthermore, one end of the air delivery hose is connected to the air outlet of the air pump 4, and the other end of the air delivery hose is connected to the connecting pipe above the movable block 53.

[0115] In use, the first motor 52 drives the first transmission rod 51 connected to it to rotate inside the cabinet 1, thereby driving the movable block 53 connected to the first transmission rod 51 to move up and down inside the cabinet 1. Then, with the cooperation of the air pump 4, the air guide block 54 and multiple sets of nozzles 55, the electronic components 2 inside the cabinet 1 can be cooled. This solves the technical problem that in current PLC electrical automation control devices on the market, when external airflow enters the interior, only the electronic components 2 near the air inlet can get a good heat dissipation effect because the position of the air inlet does not change. The heat dissipation effect of electronic components 2 in other areas of the cabinet 1 is poor, which may affect the working efficiency and service life of other electronic components 2 inside the cabinet after long-term use.

[0116] Furthermore, the second heat dissipation component 7 includes:

[0117] Fan 71 is located in the middle of the bottom plate of cabinet 1;

[0118] The second motor 72 is located above the fan 71;

[0119] The output shaft of the second motor 72 is connected to the rotating shaft of the fan 71.

[0120] In this invention, the second motor 72 causes the fan 71 to rotate inside the cabinet 1, thereby achieving the effect of cooling and heat dissipation.

[0121] Specifically, it also includes a filter assembly located below the second heat dissipation assembly 7, the filter assembly comprising:

[0122] Filter box 73 is connected to the bottom of the cabinet 1 base plate directly below the fan 71;

[0123] Filter plate 74 is slidably mounted on filter box 73;

[0124] One end of the filter plate 74 is equipped with a pull handle.

[0125] In this invention, the filter box 73 has grooves at both ends, and a filter plate 74 is slidably installed in the grooves. The filter plate 74 has sliding grooves at both ends that fit the grooves. A fan 71 is fixedly installed on the top of the filter box 73, and a second motor 72 is fixedly connected to the top of the fan 71. The fan 71 is located above the filter plate 74, and multiple sets of filter holes are opened on the bottom of the filter box 73. Through the cooperation between the filter box 73 and the filter plate 74, a certain filtering and isolation effect can be achieved against external dust, preventing dust from entering the cabinet 1 and affecting the performance of the electronic components 2 inside the cabinet 1. When it is necessary to clean the filter plate 74, the filter plate 74 can be pulled out of the filter box 73 by holding the pull handle, thereby achieving the effect of cleaning the filter plate 74.

[0126] Furthermore, the bottom of the cabinet 1 is also symmetrically provided with support legs 11, and the bottom of the support legs 11 is also provided with anti-slip rubber pads.

[0127] The cabinet door 3 is equipped with a display screen 31 above it, several buttons 32 below it, and a safety lock 33 and a handle 34 at the non-connecting end of the cabinet door 3.

[0128] In this invention, the support leg 11 and the anti-slip rubber pad at the bottom of the support leg 11 can make the entire cabinet 1 stand stably on the ground for use; through the cooperation between the display screen 31 and button 32 on the cabinet door 3 and the safety lock 33 and handle 34, the entire PLC's automated electrical control equipment can be put into normal use.

[0129] More specifically, the protective component 8 includes:

[0130] Fixing blocks 81 are symmetrically arranged on the cabinet doors 3 on both sides of the button 32;

[0131] The work box 82 is connected below the two fixed blocks 81;

[0132] The third motor 83 is connected to one side of the inside of the work box 82;

[0133] Two second transmission rods 84 are arranged opposite to each other, and the end of one of the second transmission rods 84 is connected to the output shaft of the third motor 83.

[0134] The protrusion 85 is movably mounted on the two second transmission rods 84 respectively;

[0135] Movable plate 86, which is connected between two protrusions 85;

[0136] The movable plate 86 is located outside the button 32.

[0137] In this invention, when the third motor 83 drives the second transmission rod 84 to rotate, the rotation of the second transmission rod 84 causes the movable plate 86 to move up and down along the fixed block 81. When the button 32 is not needed, the movable plate 86 can protect the button 32 to prevent the button 32 from being exposed to the air for a long time. When it is needed, the third motor 83 drives the second transmission rod 84 to rotate, causing the movable plate 86 to move downward, thereby removing the movable plate 86 from above the button 32.

[0138] More specifically, a dust baffle 87 is provided above the fixing block 81, and the dust baffle 87 is located above the button 32;

[0139] Both of the second transmission rods 84 are lead screws, or the one connected to the third motor 83 is a lead screw, and the other is a smooth guide rod;

[0140] A cleaning strip 88 is also fixedly installed on the inner side of the movable plate 86.

[0141] In this invention, the dust baffle 87 can prevent dust from adhering to the button 32 through the gaps; the cleaning strip 88 fixedly installed on the inner side of the movable plate 86 can clean the button 32 itself when the movable plate 86 moves downward.

[0142] More specifically, the movable plate 86 is provided with an observation window 861, which is made of transparent material.

[0143] In this invention, the observation window 861 on the active panel 86 allows for a direct observation of the button 32.

[0144] In this invention, the first motor 52 of the first heat dissipation component 5, the second motor 72 of the second heat dissipation component 7, and the third motor 83 of the protection component 8 are centrally controlled by a central control system. The control system receives signals from sensors, operating interfaces, or other input devices and determines the operating status of each motor according to preset logic or algorithms. In the centralized control scheme, there may not be a physical switch directly corresponding to each motor, but rather control is achieved through buttons, switches, or knobs on the software interface. This structure is a very mature approach in the prior art, and the motor configuration is not the main innovation.

[0145] In summary, a more specific embodiment of the present invention is as follows:

[0146] Example 1

[0147] Before using the above-mentioned PLC-controlled electrical heat dissipation control cabinet, the completed cabinet needs to be moved to the designated work location by appropriate handling equipment or manually.

[0148] When in use, the first heat dissipation component 5 starts to operate, the first motor 52 starts, and the first motor 52 drives the first transmission rod 51 connected to it to rotate inside the cabinet 1, thereby driving the movable block 53 connected to the first transmission rod 51 to move up and down inside the cabinet 1. Then, with the cooperation of the air pump 4, the air guide block 54 and the multiple sets of nozzles 55, the electronic components 2 inside the cabinet 1 can be cooled and dissipated.

[0149] At the same time, the second heat dissipation component 7 also operates synchronously, the second motor 72 starts, and the rotation of the second motor 72 causes the fan 71 to rotate inside the cabinet 1, thereby achieving the effect of cooling and heat dissipation.

[0150] By adopting the first heat dissipation component 5, the technical problem of only electronic components 2 near the air inlet receiving good heat dissipation due to the unchanged air inlet position in current equipment, while the heat dissipation of electronic components 2 in other areas of the cabinet 1 is poor, which may affect the working efficiency and service life of other electronic components 2 in the cabinet after long-term use, can be solved. In addition, by simultaneously dissipating heat and cooling the first heat dissipation component 5 and the second heat dissipation component 7, the problem of poor heat dissipation of PLC electrical automation control devices on the market can be solved, thereby improving working efficiency and service life.

[0151] During the above-mentioned use, the protective component 8 is also provided to protect the several buttons 32 on the cabinet door 3, and at the same time, it can also clean the buttons 32. When the protective component 8 is activated, the third motor 83 drives the second transmission rod 84 to rotate. The rotation of the second transmission rod 84 causes the movable plate 86 to move up and down along the fixed block 81, thereby moving the movable plate 86 downward and removing it from above the button 32, so that the button 32 can be operated. When the movable plate 86 moves downward, the cleaning strip 88 fixedly installed on the inner side of the movable plate 86 can clean the button 32 itself. When the button 32 is not in use, the movable plate 86 can protect the button 32 by reversing the control of the third motor 83, so as to prevent the button 32 from being exposed to the air for a long time. In addition, a dust baffle 87 is provided above the fixed block 81 to prevent dust from adhering to the button 32 from the gaps.

[0152] Because a filter assembly is provided below the second heat dissipation assembly 7, the filter box 73 and the filter plate 74 work together to filter and isolate external dust to prevent dust from entering the cabinet 1 and affecting the performance of the electronic components 2 in the cabinet 1. When the filter plate 74 needs to be cleaned, it can be pulled out from the filter box 73 by holding the pull handle, thereby achieving the effect of cleaning the filter plate 74.

[0153] Example 2

[0154] This embodiment 2 is the same as embodiment 1, except that a dust removal component 57 is also provided in the movable groove 531 below the movable block 53.

[0155] When the above structure is in use, the dust removal component 57 can blow air to a certain area. When the staff is installing and repairing electronic components 2 in the cabinet 1, they can move the dust removal component 57 to carry out special dust removal. After use, the dust removal component 57 will automatically resize and reset.

[0156] Other specific installation and usage procedures are the same as in Example 1, and will not be repeated here.

[0157] Throughout the entire implementation process described above, the size of the PLC-based electrical heat dissipation control cabinet can be adjusted according to the size and quantity of the control components to be installed inside. This patented solution requires only four I / O channels to complete all motion control, including three motors and one air pump. A separate I / O module can be configured as needed, or backup or redundant I / O channels can be used during PLC selection and design. For the entire control system, using fewer control resources to solve the heat dissipation problem of the components inside the control cabinet and improve operational reliability is an excellent technical solution.

[0158] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
