[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention will be further described below in conjunction with the embodiments.

[0034] Embodiment 1:

[0035] Reference Figure 1-7 , which is the first embodiment of the present invention, a digital twin explosion-proof unattended control device includes a controller body 1;

[0036] The controller body 1 includes physical equipment: this is the actual hardware part of the control device, including explosion-proof housing, sensors, actuators and other components. These components work in an explosion-proof environment to ensure the safety and reliability of the device. The physical equipment senses the environment through the sensor system and transmits the sensed data to the digital equipment;

[0037] Digital equipment: Digital equipment is the software and virtual part of the control device, including digital twin models, data processing modules, control algorithms, etc. Digital equipment receives the sensory data transmitted by physical equipment, and processes and analyzes it to achieve control and optimization of physical equipment;

[0038] Twin data: Twin data is the basis of the digital twin model, including the size data, structure data, spatial position and posture data of the physical equipment. These data interact with the digital equipment to jointly support the various functions and services of the digital twin control device;

[0039] Software service: Software service is an important part of the control device. It encapsulates and integrates various functions of physical equipment, digital equipment and twin data, and provides equipment services that are requestable, callable, matchable, reconfigurable and reusable. Software services are also responsible for realizing human-computer interaction and platform integration, so that the control device has efficient operation and maintenance, user-friendliness, scheduling flexibility and decision-making intelligence;

[0040] A heat dissipation fan is arranged in the controller body 1, and also includes two storage chambers 12 opened at the bottom of the controller body 1 and symmetrically on the left and right. An exhaust port 13 is opened at the bottom of the storage chamber 12 through the controller body 1, and an air inlet 15 is opened at one end of the controller body 1. The output end of the heat dissipation fan is connected with the exhaust port 13. The two blocking seats 2 are both slidably installed in the storage chamber 12, and when the adjacent sides of the two blocking seats 2 are fitted and both are located at the center of the storage chamber 12, the exhaust port 13 is just blocked to ensure that external dust and impurities will not enter the controller body 1 from the exhaust port 13, adhere to the surface of the electronic components, affect the normal heat dissipation of the electronic components, and cause the electronic components to fail to work normally;

[0041] The extrusion components all include a rotating seat 3 rotatably installed at the bottom of the two blocking seats 2, and also include extrusion strips 35 that are telescopically and slidably installed on the side walls of the corresponding blocking seats 2. The installation components all include a mounting seat 4 vertically fixedly installed on the two rotating seats 3. When the mounting seat 4 is fully rotated and stored in the corresponding storage cavity 12, the extrusion strip 35 conflicts with the inner cavity wall of the storage cavity 12. The mounting seat 4 is penetrated by a strip hole 41, and the strip hole 41 is penetrated by a mounting screw 42. When the mounting seat 4 is fully rotated and stored in the storage cavity 12, the mounting screw 42 is forced to be limited in the storage cavity 12 and cannot be detached from the storage cavity 12, which also prevents the mounting screw 42 from falling and being lost.

[0042] Embodiment 2:

[0043] Reference Figure 1-2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a cable connector 11 is installed at one end of the controller body 1 away from the air inlet 15, which is convenient for connecting with other input and output devices such as sensors and displays. The exhaust port 13 is arranged at the center of the top of the storage cavity 12, and the cavity length of the exhaust port 13 is less than the sum of the widths of the two blocking seats 2, ensuring that the two blocking seats 2 can completely block the exhaust port 13. Limiting grooves 14 are provided on the inner cavity walls of the two storage cavities 12 on the opposite sides. A filter is installed at the air inlet 15 to prevent external dust and impurities from entering the controller body 1 synchronously through airflow guidance. The two blocking seats 2 are both attached to the inner cavity walls of the corresponding storage cavities 12. The two blocking seats 2 are fixedly installed with limiting sliders 21 at one end close to the corresponding storage cavities 12, and the limiting sliders 21 are respectively slidably installed in the corresponding limiting grooves 14;

[0044] The two limit sliders 21 pass through the inner cavity of the blocking seat 2 to open a telescopic cavity, and the two extrusion strips 35 are respectively slidably installed in the telescopic cavity. The tops of the two blocking seats 2 are embedded with sealing plates 22, and the sealing plates 22 are in conflict with the tops of the corresponding storage cavities 12. The bottoms of the two blocking seats 2 are provided with long rod screws 23, and the long rod screws 23 pass through the corresponding rotating seats 3 and are threadedly installed with the corresponding sealing plates 22. When the long rod screws 23 and the sealing plates 22 are threadedly tightened, the rotating seat 3 and the blocking seat 2 can be squeezed and fixed, thereby preventing the rotating seat 3 and the blocking seat 2 from rotating relative to each other.

[0045] The remaining structures are the same as those of Example 1.

[0046] Embodiment 3:

[0047] Reference Figure 1-6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a limit plate 31 rotatably arranged in the blocking seat 2 is fixedly installed on the top of the rotating seat 3, a gear 32 is fixedly installed on the top of the limit plate 31, and a circular hole is opened through the center of the limit plate 31 and the gear 32 for the long rod screw 23 to pass through. The spacing between the limit plate 31 and the rotating seat 3 is equal to the wall thickness between the outer wall and the inner cavity of the blocking seat 2, and the outer ring wall of the gear 32 is meshed with a rack 33, and one end of the rack 33 is connected to the corresponding extrusion An L-shaped bent rod 34 is fixedly connected between the bars 35, and a roller seat is fixedly installed on the outer side wall of the mounting seat 4. A roller 43 is rotatably installed between the two opposite inner side walls of the roller seat. The roller 43 is in rolling contact with the inner wall of the storage chamber 12. When the mounting seat 4 is rotated and stored in the storage chamber 12, the roller 43 just contacts with the inner wall of the storage chamber 12. The rolling of the roller 43 facilitates the mounting seat 4, that is, the rotating seat 3 and the blocking seat 2 to slide in the storage chamber 12. The position of the blocking seat 2 is adjusted to complete the blocking of the exhaust port 13.

[0048] The remaining structure is the same as that of Example 2.

[0049] Working principle of the present invention:

[0050] The first step is to place the controller body 1 on the mounting rack, and by loosening the long rod screw 23, the rotating seat 3 can rotate relative to the blocking seat 2, thereby driving the corresponding gear 32 to rotate, thereby engaging and driving the corresponding rack 33, L-shaped bent rod 34 and extrusion strip 35 to extend and slide, until the extrusion strip 35 is retracted from the corresponding contraction cavity and no longer squeezes and conflicts with the inner cavity wall of the corresponding storage cavity 12. At this time, the blocking seat 2 can move linearly through the limiting sliding relationship between the limiting slider 21 and the limiting slide groove 14, thereby driving the entire rotating seat 3 including the mounting seat 4 to move. During the movement of the mounting seat 4, the mounting seat 4 is installed. The mounting screw 42 will also slide synchronously, and the mounting screw 42 can adjust the final mounting angle along with the rotation of the mounting base 4, that is, along with the rotation base 3. At the same time, since the mounting screw 42 is set through the strip hole 41, the model and specification of the mounting screw 42 can be replaced, which is convenient for adapting to the threaded hole on the mounting rack in the installation environment. In addition, the mounting screw 42 can also slide in the strip hole 41, so as to facilitate the alignment of the mounting screw 42 with the threaded hole on the mounting rack to complete the final threaded assembly. By fixing at multiple points around the controller body 1, the adaptive installation of the controller body 1 is completed;

[0051] In the second step, as the two blocking seats 2 slide away in the storage cavity 12, the exhaust port 13 is normally exposed. When the controller body 1 is connected to the input and output ends of other sensors, displays, etc. through the cable connector 11 and starts to work normally, the heat dissipation fan in the controller body 1 is started synchronously, and the heat generated by the operation of the electronic components in the controller body 1 is discharged from the exhaust port 13 through the heat dissipation fan, so that the pressure in the controller body 1 is reduced, so that the relatively low temperature outside air is replenished through the air inlet 15 to form a circulating cooling system;

[0052] The third step, when the controller body 1 needs to be disassembled, first unscrew the mounting screws 42 from the mounting frame, and then loosen the long rod screw 23, so that the rotating seat 3 can rotate relative to the blocking seat 2, so that the mounting seat 4 including the mounting screws 42 is completely stored in the storage cavity 12, and when the mounting seat 4 is completely stored in the storage cavity 12, and the roller 43 contacts the inner cavity wall of the storage cavity 12, the extrusion strip 35 just extends out from the telescopic cavity and conflicts with the inner cavity wall of the storage cavity 12, thereby completing the limiting fixation between the blocking seat 2 and the controller body 1, preventing the blocking seat 2 from sliding freely during the movement of the controller body 1, resulting in the exhaust port 13 being exposed, and dust and impurities entering and contaminating the electronic components.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
