[0002] An industrial intelligent gateway is a hardware device that connects industrial field equipment and information systems. An industrial gateway is also called an industrial Internet of Things intelligent gateway, a wireless data acquisition gateway, a communication acquisition gateway, a PLC wireless gateway, and an industrial communication gateway. Its main functions include data acquisition, protocol conversion, and data transmission. An industrial gateway is mainly composed of a housing, an internal storage module, a processor, a power supply, a communication interface, and a heat dissipation structure. The communication interface is used to provide a connection port for the wires of equipment such as PLCs. PLC refers to a programmable logic controller, which is usually used in computers of industrial automation control systems. It is specially designed to monitor production processes, machinery and equipment, and various parameters and conditions in industrial processes.

[0003] During the use of the industrial gateway, the electronic components inside it will generate a lot of heat. To ensure the normal operation of the industrial gateway, it is usually necessary to cool the electronic components inside the industrial gateway through structures such as heat dissipation holes or fans.

[0004] However, since industrial gateways are generally installed at industrial sites where there are a lot of dust and other impurities, a lot of dust and other impurities will be blown into the casing of the industrial gateway during the cooling process of the fan.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below.

[0020] Since industrial gateways are generally installed in dusty industrial sites, a large amount of dust and other impurities will be blown into the casing of the industrial gateway during the cooling process of the fan. Long-term use will cause the heat dissipation holes of the industrial gateway to be blocked, affecting the heat dissipation of the industrial gateway. Even dust adhering to the electronic components in the industrial gateway will directly affect its normal operation, thereby reducing the stability of the industrial gateway operation.

A torsion spring is fixedly connected between the rotating ring 6, and three fixed frames 7 evenly distributed in the circumferential direction are fixedly connected to the rotating ring 6. A sliding rod 8 is slidably connected in the fixed frame 7. An elastic member is fixedly connected between the fixed frame 7 and the adjacent sliding rod 8, wherein the elastic member is a compression spring, and the elastic force of the elastic member on the fixed frame 7 is greater than the torsion force of the torsion spring on the rotating ring 6, which is used to make the torsion spring on the rotating ring 6 twist first when the sliding rod 8 is blocked, and then the elastic member on the fixed frame 7 is contracted again, and a first wedge block 9 is fixedly connected to the position where the sliding rod 8 is away from the rotating ring 6, and the inclined side of the first wedge block 9 faces the position away from the rotating ring 6 Position, a second fixed plate 10 is fixedly connected to the first wedge blocks 9 evenly distributed in the circumference in the bellows 2, and second wedge blocks 11 evenly distributed in the circumference and squeezed and matched with all the first wedge blocks 9 are fixedly connected to the second fixed plate 10, and the inclined side of the second wedge blocks 11 faces the position of the rotating ring 6, which is used to squeeze the first wedge blocks 9, so that when the first wedge blocks 9 move along the inclined side of the adjacent second wedge blocks 11, the first wedge blocks 9 move and compress the elastic parts of the adjacent sliding rods 8, and the rear side of the sliding rods 8 is fixedly connected to a cleaning plate 12 with a brush.

[0022] Combination Figure 4 and Figure 6 As shown, a plurality of circumferentially distributed inclined sieve plates are provided on the first filter plate 301 , and the front sides of the inclined sieve plates on the first filter plate 301 are in contact with the cleaning plate 12 , so as to clean the first filter plate 301 through the cleaning plate 12 .

[0023] Combination Figure 2-Figure 4 and Figure 6As shown, a scraper 13 is fixedly connected to the first filter plate 301, and a plurality of arc-shaped tooth brushes distributed in a straight line are arranged on the scraper 13, and the arc-shaped tooth brushes on the scraper 13 are used to scrape impurities on the cleaning plate 12, and gaps are arranged between adjacent arc-shaped tooth brushes on the scraper 13 for impurities scraped from the cleaning plate 12 to enter, and a collecting channel 14 is arranged near the scraper 13 on the front side of the gateway shell 1, and the gap on the scraper 13 is connected with the collecting channel 14, and a collecting shell 15 is detachably connected to the collecting channel 14 on the gateway shell 1 through threads, and the collecting shell 15 is connected with the collecting channel 14, and is used to collect impurities scraped from the cleaning plate 12, and a second filter plate 16 symmetrically distributed front and back is installed on the collecting shell 15, and the second filter plate 16 is used to block impurities such as dust to facilitate the collection of dust.

[0024] When the operator needs to use the device to interconnect the network, the operator first fixes the device at a specified position through the hook on the left side of the gateway housing 1, and then inserts several PLC wires into different communication interfaces on the right side of the gateway housing 1 (hereinafter, the PLC wires are referred to as wires). The operator turns on the power and directly uses the device. During the use of the device, the operation of the electronic components inside the gateway housing 1 will cause the internal temperature to rise. At this time, the temperature sensor in the gateway housing 1 senses the temperature rise, and the temperature sensor converts the temperature change into an electrical signal and starts the motor 4 through the control terminal. The temperature in the gateway housing 1 is different, and the temperature sensed by the temperature sensor is different, so that the electrical signal received by the control terminal is different, and the speed of the output shaft of the motor 4 is automatically adjusted. The higher the temperature, the faster the speed of the output shaft of the motor 4, and the faster the speed at which the output shaft of the motor 4 drives the blade fan 5 to rotate. The blade fan 5 rotates and introduces the external airflow into the bellows 2, and then the airflow in the bellows 2 enters the heat dissipation holes on the front side of the gateway housing 1 through the first filter plate 301. The airflow enters the gateway housing 1 and cools the electronic components inside it. Finally, the airflow is discharged to the outside through the heat dissipation holes on the rear side of the gateway housing 1.

[0025] When the airflow enters the gateway housing 1 and cools down the internal electronic components, the output shaft of the motor 4 rotates and drives the rotating ring 6 to rotate through the torsion spring, and the rotating ring 6 drives the fixed frames 7 evenly distributed in the circumference to rotate counterclockwise (the rotation direction is Figure 1As the main view of the reference point is taken as the reference point), the fixed frame 7 drives the adjacent sliding rod 8 to rotate, and the sliding rod 8 drives the adjacent first wedge block 9 to rotate. When the first wedge block 9 rotates to contact the adjacent second wedge block 11, along with the movement of the first wedge block 9, the movement of the first wedge block 9 is temporarily blocked by the adjacent second wedge block 11, so that the sliding rod 8 and the adjacent fixed frame 7 temporarily stop rotating, and the rotating ring 6 temporarily stops rotating. The output shaft of the motor 4 drives the torsion spring of the rotating ring 6 to rotate and store force. When the torsion spring of the rotating ring 6 stores force to the limit state, the output shaft of the motor 4 rotates and drives it to rotate again through the torsion spring of the rotating ring 6, and the rotating ring 6 is The fixed frame 7 drives the adjacent sliding rod 8 to rotate, and the fixed frame 7 drives the adjacent first wedge block 9 to rotate. The first wedge block 9 moves along the inclined surface of the adjacent second wedge block 11, and the first wedge block 9 drives the adjacent sliding rod 8 to move in the direction of the rotating ring 6. At this time, the sliding rod 8 drives the adjacent cleaning plate 12 to move, and the elastic part of the sliding rod 8 is gradually compressed. The sliding rod 8 drives the adjacent cleaning plate 12 to move in the direction of the rotating ring 6. The cleaning plate 12 wipes the adjacent inclined screen plate on the first filter plate 301 during the movement and rotation process, and this cycle is repeated, and the above steps are continuously repeated to wipe and clean the first filter plate 301.

[0026] When the first wedge block 9 moves to lose contact with the inclined surface of the adjacent second wedge block 11, the second wedge block 11 loses its squeeze on the adjacent first wedge block 9, the torsion spring of the rotating ring 6 twists and resets, and the rotating ring 6 drives the adjacent sliding rod 8 to rotate quickly through the fixed frame 7, and the sliding rod 8 drives the adjacent cleaning plate 12 to rotate quickly, and at this time, the elastic part of the fixed frame 7 rebounds and resets to drive the adjacent sliding rod 8 to move quickly, and the sliding rod 8 drives the adjacent cleaning plate 12 to move quickly. The cleaning plate 12 quickly wipes the adjacent inclined screen plate on the first filter plate 301 during the movement and rotation process. The faster the rotation speed of the cleaning plate 12, the faster the torsion spring of the rotating ring 6 accumulates force, the higher the energy conversion efficiency of the torsion spring, and the torsion spring of the rotating ring 6 is. The faster the spring rebound speed is, the stronger the cleaning force of the cleaning plate 12 on the first filter plate 301 is. During the rotation of the blade fan 5, external dust enters the bellows 2 and adheres to the first filter plate 301. At this time, the cleaning plate 12 can continuously and quickly wipe the inclined screen plate on the first filter plate 301 to avoid dust adhering to the first filter plate 301 and causing it to be blocked, thereby affecting the cooling force of the airflow on the electronic components in the gateway housing 1. The faster the rotation speed of the blade fan 5 is, the faster the speed at which the external airflow carries impurities through the first filter plate 301 is. The wiping speed of the first filter plate 301 by the cleaning plate 12 will also be correspondingly accelerated, thereby realizing adaptive adjustment of the wiping speed of the first filter plate 301.

[0027] After the cleaning plate 12 wipes off the impurities on the first filter plate 301, the cleaning plate 12 rotates to contact the scraper 13. As the cleaning plate 12 moves up and down, several arc-shaped tooth brushes on the scraper 13 jointly scrape the impurities on the adjacent cleaning plates 12, so that the impurities on the cleaning plates 12 fall off into several gaps on the scraper 13. The airflow drives the impurities through the collection channel 14 into the collection shell 15, and then the airflow is discharged to the outside through the two second filter plates 16. The two layers of the second filter plates 16 block the impurities carried by the airflow, and the impurities are collected in the collection channel 14 and the collection shell 15. When the amount of impurities collected in the collection channel 14 and the collection shell 15 is too much, the operator removes the collection shell 15 and cleans the collection channel 14 and the collection shell 15, and finally installs the collection shell 15 back to its original position with threads.

[0028] When the temperature of the electronic components in the gateway housing 1 returns to normal, the temperature sensor senses the temperature change and turns off the motor 4 through the control terminal. When the operator stops using the device, he turns off the power and cleans the device.

[0029] During the use of the gateway, if the gateway moves due to accidental touching, the wires of its communication socket will be detached, and when an outsider touches the wires accidentally or maliciously, the wires will easily be pulled out of the communication socket, causing the external connection device to lose connection with the gateway, thereby affecting the stability of the operation of the external connection device.

[0030] Embodiment 2: Based on Embodiment 1, Figure 2 and Figure 7-Figure 9 As shown, it also includes a slide groove frame 17 which is symmetrically distributed up and down. The symmetrically distributed slide groove frames 17 are all fixedly connected to the front side of the gateway shell 1. A sliding frame 18 is slidingly connected in the slide groove frame 17. A connecting rod 19 is slidingly connected between the sliding frames 18 which are symmetrically distributed up and down. An elastic member is fixedly connected between the sliding frame 18 and the connecting rod 19, wherein the elastic member is a compression spring. A clamping frame 20 is slidingly connected to the sliding frame 18 in the upper limit position. An elastic member is fixedly connected between the sliding frame 18 and the adjacent clamping frame 20, wherein the elastic member is a compression spring. Inclined surfaces are provided on the opposite sides of the two clamping frames 20. The two symmetrically distributed clamping frames 20 contact and cooperate with each other. The inclined surface is used to enable the wires to pass through the two clamping frames 20 smoothly and enter between the two sliding frames 18. The distance between the symmetrically distributed slide groove frames 17 gradually decreases from left to right, so that when the two sliding frames 18 move to the right, the two sliding frames 18 gradually clamp the wires.

[0031] Combination Figure 7-Figure 9As shown, a first hydraulic telescopic rod 21 is fixedly connected to the front side of the gateway shell 1, and a first clamping plate 22 is fixedly connected to the telescopic end of the first hydraulic telescopic rod 21. An electromagnetic slider fixed to the first clamping plate 22 is slidably connected to the gateway shell 1 through an electromagnetic slide rail, and the electromagnetic slider is electrically connected to the control panel. A second clamping plate 23 is slidably connected to the first clamping plate 22, and an elastic member is fixed between the first clamping plate 22 and the second clamping plate 23, wherein the elastic member is a tension spring, and the sliding frame 18 is limitedly matched with the second clamping plate 23, and the sliding frame 18 is squeezed with the first clamping plate 22. When the first clamping plate 22 moves to the right, the first clamping plate 22 squeezes the two sliding frames 18 to move to the right. When the first clamping plate 22 moves to the left, the first clamping plate 22 will first drive the elastic member of the second clamping plate 23 to stretch, and then drive the second clamping plate 23 to move to the left, and the second clamping plate 23 drives the two sliding frames 18 to move to the left.

[0032] Combination Fig.10 and Fig.11 As shown, a second hydraulic telescopic rod 24 is fixedly connected to the gateway shell 1, and the second hydraulic telescopic rod 24 is connected to the first hydraulic telescopic rod 21 through a conduit. The telescopic end of the second hydraulic telescopic rod 24 is fixedly connected to a limit frame 25, and the limit frame 25 is slidingly connected to the gateway shell 1. The shape of the limit frame 25 is approximately C-shaped, and the limit frame 25 is located on the lower side of the gateway shell 1. A plurality of limit rods 26 in a linear array and symmetrically distributed are fixedly connected to the limit frame 25, and the number of the limit rods 26 is twice the number of the communication interface on the gateway shell 1.

[0033] In the initial state, after the wire is inserted into the adjacent communication interface on the gateway housing 1, the limit rod 26 is located on the right side of the adjacent communication interface on the gateway housing 1, and is used to block the wire inserted into the communication interface on the gateway housing 1 to prevent the wire from being pulled out of the adjacent communication interface.

[0034] When the operator inserts several wires into different communication interfaces on the right side of the gateway shell 1 respectively, the operator squeezes the two clamping frames 20 through the wires, and the clamping frames 20 move and drive their elastic parts to stretch, so that the two clamping frames 20 move back to back. After the wires pass through the two clamping frames 20, the elastic parts of the clamping frames 20 rebound and drive them to reset. In this way, all the wires are clamped between the two clamping frames 20 and the two sliding frames 18 to prevent the wires from being entangled with each other at the gateway shell 1. When the gateway shell 1 falls or the wires are accidentally pulled out of the communication interface, the wires rely on friction to pull the two sliding frames 18 to the right, and the sliding frames 18 move to the right along the adjacent slide groove frames 17 (in the process of the sliding frames 18 moving to the right, the two sliding frames 18 jointly drive the second clamping plate 23 to move to the right, and the elastic parts of the second clamping plate 23 are gradually stretched). The two sliding frames 18 move towards each other to clamp the wires, and the two elastic parts of the connecting rod 19 are gradually stretched to prevent the wires from being pulled out due to accidental touch, resulting in disconnection of the network card, thereby affecting the stability of the external connection device.

[0035] If the operator needs to disconnect the communication interface on the gateway housing 1 from the adjacent wires, the operator needs to control the electromagnetic slider on the first clamping plate 22 to move to the left through the control terminal, so that the first clamping plate 22 moves to the left while driving the telescopic end of the first hydraulic telescopic rod 21 to contract, and the first clamping plate 22 moves to the left and stretches the elastic part of the second clamping plate 23. When the elastic part of the second clamping plate 23 is stretched to the limit position, the first clamping plate 22 drives the second clamping plate 23 to move to the left through the elastic part of the second clamping plate 23, and the second clamping plate 23 drives the two sliding frames 18 to move to the left. The sliding frames 18 move to the left along the adjacent slide groove frame 17, and the two sliding frames 18 move back to back, so that the two elastic parts of the connecting rod 19 are gradually compressed, and the two sliding frames 18 lose their clamping on the cable.

[0036] During the contraction of the telescopic end of the first hydraulic telescopic rod 21, the hydraulic oil in the first hydraulic telescopic rod 21 flows along the conduit into the second hydraulic telescopic rod 24, so that the telescopic end of the second hydraulic telescopic rod 24 extends and drives the limit frame 25 to move downward, and the limit frame 25 drives several limit rods 26 thereon to move downward, and the limit rods 26 gradually move away from the adjacent communication interface on the gateway shell 1, so that the end of the wire can be pulled out from the adjacent communication interface on the gateway shell 1. Through the above steps, the wire is prevented from being directly pulled out, thereby preventing outsiders from maliciously disconnecting the connection between the gateway shell 1 and the wire, thereby increasing the stability of the connection between the gateway shell 1 and the wire.

[0037] When the operator needs to plug the wire back into the adjacent communication interface on the gateway housing 1 again, the operator repeats the above steps to place the wire between the two sliding frames 18, and then controls the electromagnetic slider of the first clamping plate 22 to move rightward and reset through the control terminal, so that the first clamping plate 22 moves rightward and drives the telescopic end of the first hydraulic telescopic rod 21 to extend and reset, and the first clamping plate 22 drives the second clamping plate 23 to move rightward, so that the elastic member of the second clamping plate 23 contracts and resets, and the first clamping plate 22 pushes the two sliding frames 18 along the adjacent slide groove frames respectively. 17 moves to the right, and the two sliding frames 18 gradually clamp the wires, and at this time the hydraulic oil in the second hydraulic telescopic rod 24 is pumped back into the first hydraulic telescopic rod 21 through the conduit, the telescopic end of the second hydraulic telescopic rod 24 shrinks and resets and drives the limit frame 25 to move upward, the limit frame 25 drives all the limit rods 26 to move upward and reset, the limit rods 26 move to align with the adjacent communication interface on the gateway housing 1, the limit rods 26 block the adjacent wire ends from detaching, and prevent the wires from being disconnected from the gateway housing 1 due to accidental or malicious touch by outsiders.

[0038] Embodiment 3: Based on Embodiment 2, Figure 1 and Fig.11As shown, a flexible block 27 is also included. The flexible block 27 is fixed between the gateway shell 1 and the limit frame 25. When the limit frame 25 moves up and down, the flexible block 27 will deform to buffer the gateway shell 1. The gateway shell 1 is fixed with a weight block 28 symmetrically distributed front and back near the flexible block 27.

[0039] Combination Figure 1 and Fig.11 As shown, a stopper 29 is fixed to the upper part of the front side of the gateway housing 1, and the thickness of the front weight 28 and the stopper 29 are both greater than the thickness of the bellows 2, which is used to prevent the bellows 2 from contacting the ground when the front side of the gateway housing 1 contacts and collides with the ground.

[0040] When the gateway shell 1 falls, due to the influence of the two weights 28, the lower side of the gateway shell 1 first contacts the ground, the limit frame 25 collides with the ground and moves upward, so that the flexible block 27 is compressed and deformed, and the limit frame 25 squeezes the telescopic end of the second hydraulic telescopic rod 24 to move upward, and the hydraulic oil in the second hydraulic telescopic rod 24 is pressurized and flows into the first hydraulic telescopic rod 21 through the conduit. The hydraulic oil in the second hydraulic telescopic rod 24 buffers the movement of the limit frame 25, and the telescopic end of the first hydraulic telescopic rod 21 extends and drives the two sliding frames 18 to move to the right along the adjacent slide frame 17 through the first clamping plate 22. The two sliding frames 18 gradually clamp the wires, and while buffering the fall of the gateway shell 1, prevent the wires from falling off from the gateway shell 1, causing the connection between the external connection equipment to be disconnected, thereby affecting the operation of the external equipment.

[0041] When the gateway housing 1 falls, if the gateway housing 1 tilts forward, the stopper 29 and the front weight 28 first contact the ground to prevent the bellows 2 from contacting the ground and causing damage to its internal parts, thereby protecting the blades 5 and other parts.

[0042] In summary, the invention includes but is not limited to the above embodiments. Any equivalent substitution or partial improvement made under the spirit and principle of the invention shall be deemed to be within the protection scope of the invention.
