Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0072] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0073] See also Figures 1-12 The embodiment of the present invention provides a modular industrial automation control cabinet, including a control cabinet body 1, and further comprising:

[0074] A main support frame 6, the main support frame 6 is fixedly installed in the control cabinet body 1, and a guide slot 14 is provided on the main support frame 6. A plurality of U-shaped heat dissipation air ducts 8 are slidably installed in the guide slot 14, and each of the U-shaped heat dissipation air ducts 8 is provided with a plurality of air holes 15, and the plurality of air holes 15 are all oriented toward the middle of the control cabinet body 1;

[0075] The control cabinet body 1 is further provided with a heat dissipation fan assembly for inflating air into the plurality of U-shaped heat dissipation ducts 8;

[0076] And a state adjustment component, which is respectively connected to the control cabinet body 1 and the U-shaped heat dissipation duct 8, and is used to drive the position state of multiple U-shaped heat dissipation ducts 8 to change when the temperature of a certain part in the control cabinet body 1 is too high, so as to achieve the purpose of centralized air blowing and heat dissipation.

[0077] See also Figures 1-12 , the state adjustment component is provided with a control system 5, and the control system 5 is electrically connected to the heat dissipation fan component;

[0078] The control system 5 is also electrically connected to a plurality of temperature sensors distributed on the main support frame 6 , and the plurality of temperature sensors are used to monitor the heat generated in different parts of the control cabinet body 1 in real time.

[0079] See also Figure 1 , further comprising: a cabinet door 3, the cabinet door 3 being rotatably connected to the control cabinet body 1, and the cabinet door 3 is also provided with a display panel and a natural ventilation port.

[0080] During the use of the control cabinet body 1, depending on factors such as the use environment, you can choose to dissipate heat only through the natural vents on the cabinet door 3, or you can use the heat dissipation fan assembly in conjunction with the natural vents to achieve mechanical ventilation. When the temperature of a certain part in the control cabinet body 1 is too high, under the detection of the temperature sensor (wherein, the temperature sensor can be installed on the main support frame 6, or can be installed at a specified position in the control cabinet body 1 to achieve comprehensive detection and detection accuracy, which will not be described in detail here), the control system 5 will control the state adjustment component to operate, and drive the position states of multiple U-shaped heat dissipation ducts 8 to change, that is, the state adjustment component will drive the U-shaped heat dissipation duct 8 adjacent to the upper or lower side of the U-shaped heat dissipation duct 8 at the part with too high temperature in the control cabinet body 1 to approach it, so as to achieve the purpose of concentrated blowing and heat dissipation. At the same time, the control system 5 will also control the power of the heat dissipation fan assembly to increase to improve The speed of air flow in the control cabinet body 1 is controlled, thereby achieving the purpose of rapid heat dissipation. When the temperature of each part in the control cabinet body 1 gradually returns to the normal range, the position of each U-shaped heat dissipation duct 8 returns to its original position. When the temperature of a certain part in the control cabinet body 1 is always at an abnormal value, the control system 5 will promptly issue an alarm to the staff's terminal device, so that the relevant staff can conduct timely inspection and processing to avoid further serious accidents, ensure the safe operation of each device in the control cabinet body 1, and extend the service life of the equipment. The operation is simple, not only can multiple U-shaped heat dissipation ducts 8 be distributed in various positions in the control cabinet body 1, ensuring the uniformity of heat dissipation in the control cabinet body 1 and improving the heat dissipation effect, but also the position status of multiple U-shaped heat dissipation ducts 8 can be adjusted according to actual needs, thereby achieving the purpose of adaptive heat dissipation, which is conducive to further improving the heat dissipation effect and extending the service life of each device.

[0081] In one embodiment of the present invention, see Figures 1-12 , the heat dissipation fan assembly includes:

[0082] A heat dissipation fan 4, wherein the heat dissipation fan 4 is fixedly mounted on the control cabinet body 1, and an output end of the heat dissipation fan 4 is connected to one of the U-shaped heat dissipation ducts 8;

[0083] The adjacent U-shaped heat dissipation ducts 8 are connected via a connecting hose 18 , and the length of the connecting hose 18 is greater than the distance between the adjacent U-shaped heat dissipation ducts 8 in a normal use state.

[0084] The connecting hose 18 is made of high-temperature resistant silicone material, and a 10% redundancy is reserved in the length to prevent the U-shaped heat dissipation duct 8 from breaking due to stretching when it moves.

[0085] In one embodiment of the present invention, the control cabinet body 1 further includes: an auxiliary support frame 7, wherein the number of the auxiliary support frames 7 is two, and the two auxiliary support frames 7 are symmetrically distributed on both side walls of the control cabinet body 1;

[0086] And a second guide slide groove 16 , the second guide slide groove 16 is opened on the auxiliary support frame 7 , wherein the U-shaped heat dissipation air duct 8 passes through the second guide slide groove 16 and is slidably connected to the second guide slide groove 16 .

[0087] During normal heat dissipation operation, the heat dissipation fan 4 is started and high-pressure air is injected into the multiple U-shaped heat dissipation ducts 8 through the connecting hose 18, and the high-pressure air is blown to various parts of the control cabinet body 1 through the multiple air holes 15, thereby achieving a good heat dissipation effect. When the position status of the multiple U-shaped heat dissipation ducts 8 needs to be adjusted, the state adjustment component will drive the specified U-shaped heat dissipation duct 8 to move slowly upward or downward in the guide slot 1 14 and the guide slot 2 16 to ensure the smooth movement of the U-shaped heat dissipation duct 8.

[0088] In one embodiment of the present invention, see Figures 1-12 , the state adjustment component includes:

[0089] A reset detection spring 13, wherein the number of the reset detection spring 13 is multiple, one end of the reset detection spring 13 is fixedly connected to the inner wall of the control cabinet body 1, and the other end of the reset detection spring 13 is fixedly connected to the U-shaped heat dissipation duct 8;

[0090] A sliding slot 9 is provided on the control cabinet body 1 and a regulating outer shell 2 is detachably mounted on the sliding slot 9;

[0091] And a positioning drive unit, which is located in the regulating outer shell 2 and passes through the sliding notch 9 to be detachably connected to the U-shaped heat dissipation duct 8.

[0092] The positioning drive unit includes:

[0093] A telescopic cylinder 12, the telescopic cylinder 12 being fixedly mounted in the regulating outer shell 2;

[0094] A lifting drive frame 10, wherein the lifting drive frame 10 is fixedly connected to the output end of the telescopic cylinder 12, and the lifting drive frame 10 is slidably connected to the inner wall of the regulating outer shell 2;

[0095] An adjusting base 11, wherein the number of the adjusting base 11 is multiple, and the multiple adjusting bases 11 are fixedly mounted on the lifting drive frame 10 and are respectively arranged opposite to the multiple U-shaped heat dissipation ducts 8;

[0096] And a Y-shaped telescopic card seat 17, which is inserted into the adjusting base 11 and connected to the adjusting base 11 through an electromagnet, and the Y-shaped telescopic card seat 17 is also detachably connected to the U-shaped heat dissipation duct 8.

[0097] When it is necessary to adjust the position state of multiple U-shaped heat dissipation ducts 8, first, according to the detection data of the temperature sensor, the control system 5 will control the electromagnet on a certain adjustment base 11 to start, wherein a telescopic cavity is provided on the adjustment base 11, and the telescopic cavity can limit the insertion part of the Y-shaped telescopic card seat 17 to prevent the Y-shaped telescopic card seat 17 from falling off from the telescopic cavity, and the insertion part can adopt a magnetic plate structure. Under normal use, the electromagnet will produce a magnetic attraction on the insertion part, so that the insertion part on the Y-shaped telescopic card seat 17 is retracted in the telescopic cavity. At this time, the Y-shaped telescopic card seat 17 and the U-shaped heat dissipation duct 8 are in a state of separation from each other, and under the control of the control system 5, the magnetism of the electromagnet on a certain adjustment base 11 will change. At this time, under the action of the magnetic repulsion force, the Y-shaped telescopic card seat 17 will extend to the outside of the adjustment base 11 and contact the outer wall of the U-shaped heat dissipation duct 8. Then, the control system 5 will control the telescopic cylinder 12 to start, thereby pushing the lifting drive frame 10 to move up or down in the control outer shell 2. When the plurality of adjustment bases 11 are driven to move, the Y-shaped telescopic bracket 17 in contact with the U-shaped heat dissipation duct 8 will drive the designated U-shaped heat dissipation duct 8 to move synchronously, while the Y-shaped telescopic bracket 17 not in contact with the U-shaped heat dissipation duct 8 will not be able to drive the U-shaped heat dissipation duct 8 to move (that is, except for the movement of the designated U-shaped heat dissipation duct 8, the other U-shaped heat dissipation ducts 8 are in a stationary state). The moving U-shaped heat dissipation duct 8 will gradually approach the U-shaped heat dissipation duct 8 at the location where the temperature in the control cabinet body 1 is too high, so as to achieve the purpose of centralized heat dissipation. After the centralized heat dissipation is completed, the various components return to their original positions. During this process, the reset detection spring 13 will, on the one hand, pull or push the designated U-shaped heat dissipation duct 8 to accurately return to the designated position and stop at the original position. On the other hand, through the extension and contraction of the reset detection spring 13, it can be determined whether the designated U-shaped heat dissipation duct 8 is operating normally in the initial adjustment state and the final reset state, thereby further monitoring the working mode of the centralized heat dissipation process to ensure the smooth implementation of the centralized heat dissipation.

[0098] In one embodiment of the present invention, see Figures 1-12 , further comprising: a heat dissipation regulating square tube 19, the heat dissipation regulating square tube 19 being fixedly connected to the U-shaped heat dissipation air duct 8 and communicating with the U-shaped heat dissipation air duct 8;

[0099] The air outlet 22 is provided on the heat dissipation regulating square tube 19 and is arranged facing the middle of the control cabinet body 1;

[0100] And an opening adjustment component, which is connected to the heat dissipation regulating square tube 19 and the air outlet 22 respectively.

[0101] The opening adjustment assembly includes:

[0102] An automatically retractable baffle 21, the automatically retractable baffle 21 is located in the air outlet 22, wherein one end of the automatically retractable baffle 21 is inserted into the cavity on the heat dissipation regulating square tube 19 and is connected to the heat dissipation regulating square tube 19 via a spring;

[0103] And a drawstring 20, one end of which passes through the heat dissipation regulating square tube 19 and is fixedly connected to the bottom end of the automatic telescopic baffle 21, and the other end of the drawstring 20 is connected to the adjacent heat dissipation regulating square tube 19 or the main support frame 6 (such as Figure 9 As shown, the bottom end of the pull strap 20 located at the bottom of the main support frame 6 is fixedly connected to the main support frame 6, and the bottom ends of other pull straps 20 are fixedly connected to adjacent heat dissipation control square tubes 19).

[0104] When the position state of the specified U-shaped heat dissipation duct 8 is adjusted, the movement of the specified U-shaped heat dissipation duct 8 will reduce the air volume in the part before the movement (due to the movement of the U-shaped heat dissipation duct 8, the distance between adjacent U-shaped heat dissipation ducts 8 will increase, thereby causing a gap in the part after the movement, affecting the heat dissipation of this part), and the local temperature of the new position may be too high. Therefore, during the movement of the specified U-shaped heat dissipation duct 8 (for example, the specified U-shaped heat dissipation duct 8 moves downward), the specified U-shaped heat dissipation duct 8 will drive the pull belt 20 above it to move downward, wherein the pull belt 20 can be made of elastic material, and after the pull belt 20 moves down a certain length, it will pull the automatic telescopic baffle 21 to move downward in the cavity, wherein a limit block is provided in the cavity to keep the heat dissipation control square tube 19 in a normal working state, and under the elastic force of the spring and the limiting action of the limit block, the automatic telescopic baffle 21 can be at the highest position in the cavity. The top of the automatic telescopic baffle 21 is spaced a distance from the inner top wall of the air outlet 22, which prevents the air outlet 22 from being completely blocked, which is beneficial to ventilation and heat dissipation under normal working conditions. Under the pulling action of the pull belt 20, the automatic telescopic baffle 21 will overcome the elastic force of the spring at the bottom of the automatic telescopic baffle 21 and move downward in the cavity, thereby increasing the opening size of the air outlet 22, so that a larger amount of air can flow out from the top of the designated U-shaped heat dissipation duct 8, thereby filling the vacancy in the position after the designated U-shaped heat dissipation duct 8 moves, and ensuring uniform heat dissipation. For other pull belts 20 that are in a normal state or a relaxed state, the opening size of the air outlet 22 remains unchanged under the elastic force of the spring and the limiting action of the limit block, and normal ventilation and heat dissipation are carried out, thereby saving resources while performing adaptive heat dissipation operations on various parts of the control cabinet body 1, which is beneficial to improving the heat dissipation effect.

[0105] In one embodiment of the present invention, see Figures 1-12 The workflow of the control system 5 specifically includes the following steps:

[0106] Step 1: Temperature detection and positioning;

[0107] The temperature sensor collects the temperature data of each part in the control cabinet body 1 in real time and transmits it to the control system 5;

[0108] Local temperature deviation: ΔT=T max -T avg , where T max is the maximum temperature, T avg is the average temperature inside the cabinet;

[0109] If ΔT ≥ 10°C, the centralized cooling mode is triggered;

[0110] Step 2: Select the target U-shaped heat dissipation duct 8;

[0111] The control system 5 determines the nearest U-shaped heat dissipation duct (reference duct) and the adjacent duct (target duct) to the high-temperature area based on the coordinates of the temperature sensor;

[0112] Select the target tube on the upper or lower side of the reference tube and move it closer to the reference tube;

[0113] Step 3: Target tube displacement control;

[0114] The electromagnet is energized, and the Y-shaped telescopic holder 17 of the target tube is locked with the target tube;

[0115] The telescopic cylinder 12 drives the lifting drive frame 10 to move, and the displacement d=k·ΔT, where k is the proportional coefficient, which is 0.5mm / °C by default;

[0116] The reset detection spring 13 provides real-time feedback on the displacement status to ensure that the target tube is accurately docked;

[0117] Step 4: Dynamically adjust the air volume;

[0118] The power of the cooling fan 4 is adjusted according to P=P0+α·ΔT, where P0 is the reference power and α is the gain coefficient;

[0119] Step 5: Verify the heat dissipation effect;

[0120] The temperature sensor continuously monitors. If ΔT < 5°C for more than 5 minutes, all components are reset:

[0121] The Y-shaped telescopic holder 17 is unlocked;

[0122] The reset detection spring 13 pulls the target tube back to the initial position;

[0123] The power of cooling fan 4 is restored to P0;

[0124] Step 6: Abnormal alarm;

[0125] If the high temperature persists (ΔT ≥ 15°C for more than 30 minutes), the control system 5 sends an alarm signal to the operation and maintenance terminal via the 4G module, including:

[0126] High temperature coordinate position;

[0127] Historical temperature curve;

[0128] It is recommended to inspect components (such as failure of cooling fan 4 or blockage of air duct, etc.).
