Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of gateway devices, and specifically refers to an edge gateway device with a heat dissipation mechanism. Background Art

[0002] An edge gateway is an intelligent device deployed at the edge of a network, located between Internet of Things devices and a cloud computing platform, and is used to process and analyze data and perform computing tasks near the data source or user. It connects the physical world and the digital world to achieve data collection, processing, transmission, and storage, reducing data transmission latency and improving system response speed. It is a new generation of communication system device.

[0003] A Raspberry Pi edge gateway with a heat dissipation mechanism mentioned in an existing Chinese published patent (authorization announcement number: CN216795021U). It includes a housing, a heat dissipation mechanism, and a device gateway body. The heat dissipation mechanism is installed on the housing. The heat dissipation mechanism is provided with heat sinks. The top of the heat sink is fixed with a ventilation box through fixing columns, and the bottom of the heat sink is screwed to the device gateway body through a connecting rod. A through groove is provided at the center of the bottom of the ventilation box, and a ventilation blade is rotatably provided in the through groove; a partition is provided above the through groove, and the partition divides the ventilation box into a primary air adjustment port and a secondary air adjustment port. A first exhaust fan with a push plate seal is provided at the top of the primary air adjustment port. A semiconductor refrigeration sheet is embedded at the bottom of the secondary air adjustment port and a rotating door is provided at the top; second exhaust fans are provided on opposite sides of the side wall of the housing. The present invention solves the drawbacks of low heat dissipation efficiency and inability to perform hierarchical heat dissipation of existing Raspberry Pi edge gateway devices and is suitable for popularization and use.

[0004] In a communication system device, a gateway device generates heat during use. Traditional gateway devices design many heat dissipation holes on the bottom surface of the device for heat dissipation. Dust in the air will enter the traditional circulating heat dissipation gateway device through the heat dissipation holes. In addition, components in the traditional circulating heat dissipation gateway device generate static electricity. After long-term use, a large amount of dust will be adsorbed and accumulated on these components, which will shorten the service life of the circulating heat dissipation gateway device. The dust accumulated in the holes will gradually block the heat dissipation holes, resulting in a gradual deterioration of the heat dissipation effect. At this time, the heat dissipation gateway device needs to be cleaned regularly to restore a good heat dissipation effect. When cleaning the traditional circulating heat dissipation gateway device, cleaning tools are needed to clean the dust in the holes, and this process will raise dust, and the dust will float into the interior of the device, thus affecting the normal use of the device. Summary of the Invention

[0005] The object of the present application is to: To solve the problem that in the existing gateway device in the new generation of communication system equipment, heat dissipation is carried out by setting holes, which is likely to cause the holes to be blocked by dust, resulting in a decrease in the heat dissipation effect, and also cause dust adhesion, making the components generate static electricity. The present application provides an edge gateway device with a heat dissipation mechanism.

[0006] In order to achieve the above object, the present application specifically adopts the following technical solutions: An edge gateway device with a heat dissipation mechanism, including a gateway body, a circuit board is fixedly connected inside the gateway body, several electrical components are fixedly connected inside the circuit board, a driving motor is fixedly connected to the outer surface of the gateway body, the output end of the driving motor penetrates the gateway body and is fixedly connected to a driving rod, the driving rod is rotatably connected to the inside of the gateway body, several fans are installed inside the gateway body, one end of the fan is fixedly connected to a cooling bevel gear one, several cooling bevel gears two are fixedly connected to the outer surface of the driving rod, the outer surface of the cooling bevel gear one meshes with the cooling bevel gear two, a dust blocking plate is slidably arranged inside the gateway body, a connecting roller is rotatably connected inside the gateway body, a filter screen is sleeved on the outer surface of the connecting roller, a brush is arranged on the outer surface of the gateway body, and a dust prevention structure is arranged inside the gateway body.

[0007] By adopting the above technical solutions, when the gateway body operates, when the edge gateway is in use, the heat inside it gradually accumulates with the use time. While the edge gateway is in use, start the driving motor to drive the driving rod to rotate. Through the rotation of the driving rod, several cooling bevel gears two are driven to rotate, so that the cooling bevel gear two drives the cooling bevel gear one to rotate. With the rotation of each cooling bevel gear one, the corresponding fan is driven to rotate, thereby generating a flow of air. Let the air flow through the filter screen and then enter the inside of the gateway body to flow, so as to dissipate heat and cool down the electrical components on the circuit board. Then the air flow flows out of the gateway body through the dust blocking plate. When the air flow enters the gateway body, the filter screen will block the outside dust from entering the inside of the gateway body, avoiding the influence of dust on the electrical components. At the same time, the brush will automatically rotate to clean the dust on the filter screen, avoiding the blockage of the filter screen. The dust blocking plate can seal the inside of the gateway body when the edge gateway is not in use to prevent dust from entering. When it is necessary to clean the dust, the dust blocking plate can be pulled out from the gateway body and then cleaned. Through the above treatment method of dust, the dust generated during cleaning is avoided, and the cleaned dust will fall outside the gateway body to be cleaned, so that the dust will not adhere to the electrical components and affect the service life of the equipment. At the same time, the edge gateway device can effectively dissipate heat and cool down during long-term use, and also makes the device more convenient to clean dust.

[0008] Furthermore, the dust-proof structure includes a connecting bevel gear I fixedly connected to the end of the driving rod. A connecting column is rotatably connected inside the gateway body. One end of the connecting column is fixedly connected with a connecting bevel gear II. The outer surface of the connecting bevel gear I meshes with the connecting bevel gear II. The other end of the connecting column is fixedly connected with a cleaning bevel gear I. A cleaning bevel gear II meshes with the outer surface of the cleaning bevel gear I. One side of the cleaning bevel gear II is fixedly connected with a cleaning rod. The filter net is sleeved on the outer surface of the cleaning rod. The end of the cleaning rod is rotatably connected with the gateway body.

[0009] By adopting the above technical solution, as the driving rod rotates, the connecting bevel gear I at its end also rotates. The rotation of the connecting bevel gear I drives the connecting bevel gear II meshing with it, thereby driving the connecting column to rotate. This makes the cleaning bevel gear I fixedly connected to the other end of the connecting column also rotate accordingly. The cleaning bevel gear II meshing with the cleaning bevel gear I drives the cleaning rod to rotate. While the cleaning rod rotates, it drives the filter net to rotate. The dust in the air flow will not accumulate on the same part of the filter net when being filtered by the filter net, but will be evenly distributed on the surface of the filter net during the rotation of the filter net. After the dust adheres to the filter net and moves one week, it is cleaned by the brush. Since the adhered dust is cleaned in time, dust is not likely to accumulate on the filter net, which also makes it difficult to generate dust during the cleaning process, reduces the dust adhering to the electrical components, and protects the service life of the device. Moreover, when the air flow passes through, the filter net forms two layers to filter the dust in the air flow twice, further enhancing the dust filtering effect of the device and reducing the possibility of dust entering the gateway body during the heat dissipation work.

[0010] Furthermore, a cleaning roller is rotatably connected inside the gateway body. The end of the cleaning roller penetrates the gateway body and is fixedly connected with the brush. Belts are sleeved on the outer surfaces of both the cleaning roller and the cleaning rod.

[0011] By adopting the above technical solution, the cleaning roller rotates synchronously with the cleaning rod through the belt. This makes the cleaning roller drive the brush to rotate to clean the surface of the filter net. Since the adhered dust is cleaned in time, dust is not likely to accumulate on the filter net, which also makes it difficult to generate dust during the cleaning process, reduces the dust adhering to the electrical components, and protects the service life of the device.

[0012] Furthermore, a fixed column is fixedly connected to the outer surface of the gateway body. An arc-shaped collecting plate is rotatably connected to the outer surface of the fixed column. A cleaning torsion spring is sleeved outside the fixed column. Both ends of the cleaning torsion spring are fixedly connected with the arc-shaped collecting plate and the fixed column respectively.

[0013] By adopting the above technical solution, when dust is brushed off the surface of the filter screen by the brush, the arc-shaped collecting plate will maintain a certain opening angle under the action of the cleaning torsion spring, which will make the arc-shaped collecting plate continuously resist the bristles of the brush, so that the dust collected on the bristles can be scraped off by the arc-shaped collecting plate during the rotation of the brush, and the fallen dust will fall onto the upper surface of the arc-shaped collecting plate, achieving centralized collection of the dust. This also cleans the brush and prevents the brush from causing secondary pollution of dust scattering due to excessive dust accumulation during long-term operation.

[0014] Furthermore, a guiding column is fixedly connected inside the gateway body. The outer surface of the guiding column is slidably connected with a dust-blocking plate, and a handle is fixedly connected to one end of the dust-blocking plate.

[0015] By adopting the above technical solution, the dust-blocking plate can seal the inside of the gateway body when the edge gateway is not in use to prevent dust from entering. When it is necessary to clean the dust, the handle can be pulled to extract the dust-blocking plate from the gateway body. During the movement of the dust-blocking plate, it is guided by the guiding column to make the movement of the dust-blocking plate more stable. When the dust-blocking plate leaves the gateway body, the dust-blocking plate can be cleaned intensively, and the space of the dust-blocking plate is also opened to make it more convenient for manual maintenance of the inside of the gateway body. By the above dust treatment method, the dust generation during dust cleaning is avoided.

[0016] Furthermore, a rotating column is rotatably connected inside the gateway body. A cleaning plate is fixedly connected to the outer surface of the rotating column, and a scraping plate is fixedly connected to the end of the cleaning plate.

[0017] By adopting the above technical solution, while the dust-blocking plate is moving, the cleaning plate and the scraping plate at its end scrape and clean the dust attached to the outside of the dust-blocking plate.

[0018] Furthermore, a pressing torsion spring is sleeved outside the rotating column, and both ends of the pressing torsion spring are fixedly connected to the cleaning plate and the gateway body respectively.

[0019] By adopting the above technical solution, under the action of the pressing torsion spring, the cleaning plate and the scraping plate at its end are helped to closely adhere to the surface of the filter screen, strengthening the scraping effect of the dust on the dust-blocking plate.

[0020] Furthermore, a liquid storage box is fixedly connected inside the gateway body. A cooling pipe is fixedly connected inside the circuit board. One end of the cooling pipe is fixedly connected with a connecting pipe, and the lower end of the connecting pipe is fixedly connected with the liquid storage box.

[0021] By adopting the above technical solution, as the coolant flows, when it passes through the cooling pipe, it absorbs the heat generated by the circuit board to achieve the cooling effect on the circuit board. Then the coolant passes through the cooling pipe again and flows back to the liquid storage box through the connecting pipe. Subsequently, the coolant enters the cooling pipe again for heat dissipation circulation.

[0022] Furthermore, the other end of the cooling pipe is fixedly connected to a liquid inlet pipe, the end of the liquid inlet pipe is fixedly connected to a water pump, one side of the water pump is fixedly connected to a heat-conducting copper pipe, the heat-conducting copper pipe is distributed in an S shape, the end of the heat-conducting copper pipe is fixedly connected to a liquid outlet pipe, and the end of the liquid outlet pipe is fixedly connected to the liquid storage box.

[0023] By adopting the above technical solution, the rotating fan will generate an air flow to continuously take away the temperature of the heat-conducting copper pipe 9 to cool it down. The heat-conducting copper pipe is distributed in an S shape inside the gateway body, greatly increasing the contact area between the heat-conducting copper pipe and the air flow and improving the cooling efficiency of the heat-conducting copper pipe. At the same time, the S-shaped heat-conducting copper pipe also has a larger contact area with the coolant, and the coolant is in contact with the heat-conducting copper pipe for a longer time, enabling the coolant passing through the heat-conducting copper pipe to be restored to a suitable temperature for cooling. This ensures that the device will not experience a decline in cooling effect due to the increase in the temperature of the coolant during long-term use. Subsequently, the cooled coolant is pumped by the water pump and enters the liquid inlet pipe through the inside of the water pump. As the coolant flows, it enters the cooling pipe through the liquid inlet pipe, and the cooling pipe is cooled by the movement of the coolant in the cooling pipe. The cooling pipe absorbs the heat generated by the circuit board, thereby achieving the effect of cooling the circuit board. Then, the coolant flows back to the liquid storage box through the connecting pipe after passing through the cooling pipe, and then the coolant flows back into the heat-conducting copper pipe through the liquid outlet pipe again, completing a heat dissipation cycle.

[0024] Furthermore, a first conduction gear plate is fixedly connected to the upper surface of the liquid storage box, a second conduction gear plate is fixedly connected to the lower surface of the circuit board, the outer surfaces of the first conduction gear plate and the second conduction gear plate are both distributed with alternately fixed racks, and both the first conduction gear plate and the second conduction gear plate are made of heat-conducting copper plates. By adopting the above technical solution, the first conduction gear plate on the upper surface of the liquid storage box meshes with the second conduction gear plate on the lower surface of the circuit board, increasing the contact area between the liquid storage box and the circuit board and enabling the heat generated by the circuit board to be quickly transferred to the liquid storage box directly through the first conduction gear plate and the second conduction gear plate, further improving the heat dissipation efficiency.

[0025] In summary, the present application includes at least one of the following beneficial effects; 1. In the present application, when the device needs to dissipate heat, the driving motor is started to drive the driving rod to rotate. The rotation of the driving rod drives several fans to rotate, thereby generating wind flow. At the same time, the rotation of the driving rod also drives the cleaning rod to rotate, and the cleaning roller is rotated synchronously with the cleaning rod through the belt, so that the cleaning roller drives the brush to rotate and the brush cleans the surface of the filter. Since the filter continues to reciprocate like a conveyor belt, the dust in the airflow will not be attached to the same part of the filter when it is filtered by the filter, but will be evenly distributed on the surface of the filter during the rotation of the filter, and the dust will be cleaned by the brush after the filter moves for one circle after being attached to the filter. The arc-shaped collection plate will maintain a certain opening angle under the action of the cleaning torsion spring, which will make the arc-shaped collection plate continuously resist the bristles of the brush, so that the dust collected on the bristles will be scraped off by the arc-shaped collection plate during the rotation of the brush, and the fallen dust will fall to the upper surface of the arc-shaped collection plate to collect the dust in a centralized manner. The above dust treatment method avoids the dust caused by cleaning the accumulated dust, and the cleaned dust will fall on the outside of the gateway body for cleaning, so that the dust will not adhere to the electrical components and affect the service life of the equipment. At the same time, the edge gateway device can effectively dissipate heat and cool down when used for a long time, and it also makes the device more convenient to clean dust.

[0026] 2. In the present application, when the edge gateway is not in use, the dust blocking plate seals the inside of the gateway body to prevent dust from entering. When dust needs to be cleaned, the handle can be pulled out of the dust blocking plate from the gateway body. The cleaning plate and the shovel plate at its end are tightly attached to the surface of the filter screen under the action of the torsion spring to scrape and clean the dust attached to the outside of the dust blocking plate. The above dust handling method avoids the dust caused by cleaning the accumulated dust, and the cleaned dust will fall on the outside of the gateway body to be cleaned, making the device more convenient when cleaning dust.

[0027] 3. In the present application, when the device is dissipating heat, the water pump draws the coolant inside the liquid storage box into the heat-conducting copper tube through the liquid outlet pipe, and the rotating fan generates wind flow to continuously take away the temperature of the heat-conducting copper tube to cool it down, and cools the coolant through the heat-conducting copper tube. The cooled coolant is drawn by the water pump and allowed to pass through the inside of the water pump into the liquid inlet pipe. As the coolant flows, it passes through the liquid inlet pipe, the cooling pipe, and the connecting pipe and finally returns to the liquid storage box to complete a heat dissipation cycle. At the same time, the heat generated by the circuit board can be directly transferred to the liquid storage box through the conduction tooth plate 1 and the conduction tooth plate 2, which further improves the heat dissipation efficiency. Through the above structure, the heat dissipation effect of the device combines the advantages of air cooling and water cooling, further improving the heat dissipation effect of the gateway body when in use.

Detailed implementation manners

[0030] Next, in combination with the Figures 1 - 11, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 With Figure 2 , Figure 3 , the present invention provides a technical solution: an edge gateway device with a heat dissipation mechanism, including a gateway body 1, a circuit board 2 is fixedly connected inside the gateway body 1, a plurality of electrical components 3 are fixedly connected inside the circuit board 2, a drive motor 5 is fixedly connected to the outer surface of the gateway body 1, the output end of the drive motor 5 penetrates the gateway body 1 and is fixedly connected to a drive rod 7, the drive rod 7 is rotatably connected to the inside of the gateway body 1, a plurality of fans 10 are installed inside the gateway body 1, one end of the fan 10 is fixedly connected to a cooling bevel gear one 11, a plurality of cooling bevel gears two 12 are fixedly connected to the outer surface of the drive rod 7, the outer surface of the cooling bevel gear one 11 meshes with the cooling bevel gear two 12, a dust blocking plate 6 is slidably arranged inside the gateway body 1, a connecting roller 16 is rotatably connected to the inside of the gateway body 1, a filter screen 4 is sleeved on the outer surface of the connecting roller 16, a brush 29 is arranged on the outer surface of the gateway body 1, and a dust prevention structure is arranged inside the gateway body 1.

[0032] When the edge gateway connects the physical world and the digital world to realize data collection, processing, transmission and storage, the heat inside it gradually accumulates over time. While the edge gateway is in use, start the drive motor 5 to drive the drive rod 7 to rotate. The rotation of the drive rod 7 drives several cooling bevel gears II 12 to rotate, so that the cooling bevel gears II 12 drive the cooling bevel gears I 11 to rotate. With the rotation of each cooling bevel gear I 11, the corresponding fan 10 is driven to rotate, thereby generating an air current. Let the air current pass through the filter screen 4 and then enter the gateway body 1 for internal flow, so as to dissipate heat and cool the electrical components 3 on the circuit board 2. Then the air current flows to the outside of the gateway body 1 through the dust blocking plate 6. When the air flow enters the gateway body 1, the filter screen 4 will block the outside dust from entering the gateway body 1, avoiding the influence of dust on the electrical components 3. At the same time, the brush 29 will automatically rotate to clean the dust on the filter screen 4, avoiding the blockage of the filter screen 4. The dust blocking plate 6 can close the inside of the gateway body 1 when the edge gateway is not in use to prevent dust from entering. When it is necessary to clean the dust, the dust blocking plate 6 can be pulled out from the gateway body 1 and then cleaned. Through the above dust treatment method, the dust generated during cleaning is avoided, and the cleaned dust will fall outside the gateway body 1 to be cleaned, so that the dust will not adhere to the electrical components 3 and affect the service life of the equipment. At the same time, the edge gateway device can effectively dissipate heat and cool down during long-term use, and it is also more convenient for the device to clean dust.

[0033] Refer to Figure 3 And Figure 4 , Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 11 , the dust-proof structure includes a connecting bevel gear I 17 fixedly connected to the end of the drive rod 7. A connecting column 19 is rotatably connected inside the gateway body 1. One end of the connecting column 19 is fixedly connected with a connecting bevel gear II 18. The outer surface of the connecting bevel gear I 17 meshes with the connecting bevel gear II 18. The other end of the connecting column 19 is fixedly connected with a cleaning bevel gear I 20. A cleaning bevel gear II 21 meshes with the outer surface of the cleaning bevel gear I 20. One side of the cleaning bevel gear II 21 is fixedly connected with a cleaning rod 22. The filter screen 4 is sleeved on the outer surface of the cleaning rod 22. The end of the cleaning rod 22 is rotatably connected to the gateway main body 1. A cleaning roller 27 is rotatably connected inside the gateway body 1. The end of the cleaning roller 27 penetrates through the gateway body 1 and is fixedly connected with the brush 29. Belts 28 are sleeved on the outer surfaces of the cleaning roller 27 and the cleaning rod 22. A fixed column 31 is fixedly connected to the outer surface of the gateway body 1. An arc-shaped collecting plate 30 is rotatably connected to the outer surface of the fixed column 31. A cleaning torsion spring 32 is sleeved outside the fixed column 31. Two ends of the cleaning torsion spring 32 are respectively fixedly connected with the arc-shaped collecting plate 30 and the fixed column 31; Inside the gateway body 1, a guiding column 35 is fixedly connected. The outer surface of the guiding column 35 is slidably connected to the dust-proof plate 6. One end of the dust-proof plate 6 is fixedly connected to a grip 15. Inside the gateway body 1, a rotating column 36 is rotatably connected. The outer surface of the rotating column 36 is fixedly connected to a cleaning plate 33. The end of the cleaning plate 33 is fixedly connected to a scraping plate 34. A pressing torsion spring 37 is sleeved outside the rotating column 36. Two ends of the pressing torsion spring 37 are respectively fixedly connected to the cleaning plate 33 and the gateway body 1. When the device needs to dissipate heat, start the drive motor 5 to drive the drive rod 7 to rotate. Through the rotation of the drive rod 7, a number of cooling bevel gears II 12 are driven to rotate, so that the cooling bevel gears II 12 drive the cooling bevel gears I 11 to rotate. With the rotation of each cooling bevel gear I 11, the corresponding fan 10 is driven to rotate, thereby generating a wind current. At the same time, with the rotation of the drive rod 7, the connecting bevel gear I 17 at its end also rotates. The rotation of the connecting bevel gear I 17 drives the meshing connecting bevel gear II 18, thereby driving the connecting column 19 to rotate. This makes the cleaning bevel gear I 20 fixedly connected to the other end of the connecting column 19 also rotate accordingly. The cleaning bevel gear II 21 meshing with the cleaning bevel gear I 20 drives the cleaning rod 22 to rotate. While the cleaning rod 22 rotates, it drives the filter net 4 to rotate. At the same time, the rotation of the cleaning rod 22 drives the belt 28 to rotate. The belt 28 drives the cleaning roller 27 to rotate. This makes the cleaning roller 27 drive the brush 29 to rotate to clean the surface of the filter net 4. Since the filter net 4 continuously rotates in a reciprocating manner like a conveyor belt, the dust in the air flow will not accumulate on the same part of the filter net 4 when being filtered by the filter net 4, but will be evenly distributed on the surface of the filter net 4 during the rotation of the filter net 4. After the dust adheres to the filter net 4 and moves one week, it is cleaned by the brush 29. Since the adhering dust is cleaned in time, dust is not likely to accumulate on the filter net 4, which also makes it not easy to generate dust during the cleaning process, reducing the dust adhering to the electrical components 3 and protecting the service life of the device. Moreover, when the air flow passes through, the filter net 4 forms two layers to filter the dust in the air flow twice, further enhancing the dust filtering effect of the device and reducing the possibility of dust entering the gateway body 1 during the heat dissipation work. When the dust is brushed off the surface of the filter net 4 by the brush 29, the arc-shaped collecting plate 30 will maintain a certain opening angle under the action of the cleaning torsion spring 32. This will make the arc-shaped collecting plate 30 continuously resist the bristles of the brush 29, so that during the rotation of the brush 29, the dust collected on the bristles is scraped off by the arc-shaped collecting plate 30, and the fallen dust falls onto the upper surface of the arc-shaped collecting plate 30 for centralized collection. This also cleans the brush 29 and prevents the brush 29 from causing secondary pollution of dust scattering due to excessive dust accumulation during long-term work. When cleaning the dust in the arc-shaped collecting plate 30, just wipe it from one end to the other end of the arc-shaped collecting plate 30 with a wet wipe to clean it, making the cleaning of the arc-shaped collecting plate 30 very convenient. While the dust blocking plate 6 can enclose the inside of the gateway body 1 when the edge gateway is not in use to prevent dust from entering, when dust needs to be cleaned, the grip 15 can be pulled to extract the dust blocking plate 6 from the gateway body 1. During the movement of the dust blocking plate 6, it is guided by the guide post 35 to make the movement of the dust blocking plate 6 more stable. While the dust blocking plate 6 is moving, the cleaning plate 33 and the scraper plate 34 at its end are tightly attached to the surface of the filter screen 4 under the action of the compression spring 37 to scrape and clean the dust attached to the outside of the dust blocking plate 6. When the dust blocking plate 6 leaves the gateway body 1, the dust blocking plate 6 can be cleaned intensively, and the space of the dust blocking plate 6 is also opened to make it more convenient for manual maintenance of the inside of the gateway body 1. By the above dust treatment method, the dust generated during cleaning is avoided, and the cleaned dust will fall outside the gateway body 1 to be cleaned, so that the dust will not adhere to the electrical components 3 and affect the service life of the equipment. At the same time, the edge gateway device can effectively dissipate heat and cool down during long-term use, and it is also more convenient for the device to clean dust.

[0034] Refer to Figure 3 And Figure 7 , Figure 8 , a liquid storage box 23 is fixedly connected inside the gateway body 1, a cooling pipe 14 is fixedly connected inside the circuit board 2, one end of the cooling pipe 14 is fixedly connected with a connecting pipe 38, and the lower end of the connecting pipe 38 is fixedly connected with the liquid storage box 23. The other end of the cooling pipe 14 is fixedly connected with a liquid inlet pipe 13, the end of the liquid inlet pipe 13 is fixedly connected with a water pump 8, one side of the water pump 8 is fixedly connected with a heat conduction copper pipe 9, the heat conduction copper pipe 9 is distributed in an S shape, the end of the heat conduction copper pipe 9 is fixedly connected with a liquid outlet pipe 26, and the end of the liquid outlet pipe 26 is fixedly connected with the liquid storage box 23. A conduction tooth plate one 24 is fixedly connected to the upper surface of the liquid storage box 23, a conduction tooth plate two 25 is fixedly connected to the lower surface of the circuit board 2, the outer surfaces of the conduction tooth plate one 24 and the conduction tooth plate two 25 are both distributed with alternately fixed racks, and the conduction tooth plate one 24 and the conduction tooth plate two 25 are both heat conduction copper plates.

[0035] When the device dissipates heat, the water pump 8 is started to work. The water pump 8 pumps the coolant inside the liquid storage box 23 into the heat-conducting copper tube 9 through the liquid outlet pipe 26. The rotating fan 10 generates an air current to continuously take away the temperature of the heat-conducting copper tube 9 to cool it down. The heat-conducting copper tube 9 is distributed in an S shape inside the gateway main body 1, greatly increasing the contact area between the heat-conducting copper tube 9 and the air current and improving the cooling efficiency of the heat-conducting copper tube 9. At the same time, the S-shaped distributed heat-conducting copper tube 9 also makes the contact area between the coolant and the heat-conducting copper tube 9 larger, and the time for the coolant to be cooled by the heat-conducting copper tube 9 is longer, enabling the coolant passing through the heat-conducting copper tube 9 to be restored to a suitable temperature for cooling. This ensures that the cooling effect of the device will not decrease due to the increase in the temperature of the coolant during long-term use. Subsequently, the cooled coolant is pumped by the water pump 8 and passes through the inside of the water pump 8 and into the liquid inlet pipe 13. As the coolant flows, it enters the cooling pipe 14 through the liquid inlet pipe 13, and the cooling pipe 14 is cooled by the movement of the coolant inside the cooling pipe 14. The cooling pipe 14 absorbs the heat generated by the circuit board 2 to achieve the cooling effect on the circuit board 2. Then, the coolant passes through the cooling pipe 14 and then flows back to the liquid storage box 23 through the connecting pipe 38. Subsequently, the coolant flows back into the heat-conducting copper tube 9 through the liquid outlet pipe 26 again to complete a heat dissipation cycle. At the same time, the conduction tooth plate 1 24 on the upper surface of the liquid storage box 23 meshes with the conduction tooth plate 2 25 on the lower surface of the circuit board 2, increasing the contact area between the liquid storage box 23 and the circuit board 2 and enabling the heat generated by the circuit board 2 to be quickly transferred to the liquid storage box 23 directly through the conduction tooth plate 1 24 and the conduction tooth plate 2 25, further improving the heat dissipation efficiency. Through the above structure, the heat dissipation effect of the device combines the advantages of air cooling and water cooling, further enhancing the heat dissipation effect when the gateway body 1 is in use.

[0036] Working principle: When the device needs to dissipate heat, the drive motor 5 is started. The drive motor 5 drives the drive rod 7 to rotate. The rotation of the drive rod 7 drives several cooling bevel gears II 12 to rotate, causing the cooling bevel gears II 12 to drive the cooling bevel gears I 11 to rotate. With the rotation of each cooling bevel gear I 11, the corresponding fan 10 is driven to rotate, thereby generating an air current. At the same time, with the rotation of the drive rod 7, the connecting bevel gear I 17 at its end also rotates. The rotation of the connecting bevel gear I 17 drives the meshing connecting bevel gear II 18, thereby driving the connecting column 19 to rotate. This makes the cleaning bevel gear I 20 fixedly connected to the other end of the connecting column 19 also rotate. The cleaning bevel gear II 21 meshing with the cleaning bevel gear I 20 drives the cleaning rod 22 to rotate. While the cleaning rod 22 rotates, it drives the filter net 4 to rotate. At the same time, the rotation of the cleaning rod 22 drives the belt 28 to rotate. The belt 28 drives the cleaning roller 27 to rotate. This makes the cleaning roller 27 drive the brush 29 to rotate, and the brush 29 cleans the surface of the filter net 4. Since the filter net 4 continuously rotates in a reciprocating manner like a conveyor belt, the dust in the air current will not accumulate on the same part of the filter net 4 when being filtered by the filter net 4, but will be evenly distributed on the surface of the filter net 4 during the rotation of the filter net 4. After the dust adheres to the filter net 4 and moves one week, it is cleaned by the brush 29. Since the adhered dust is cleaned in time, it is not easy to accumulate dust on the filter net 4. This also makes it not easy to generate dust during the cleaning process, reducing the dust adhering to the electrical components 3 and protecting the service life of the device. Moreover, when the air current passes through, the filter net 4 forms two layers to filter the dust in the air current twice, further enhancing the dust filtering effect of the device and reducing the possibility of dust entering the gateway body 1 during the heat dissipation work. When the dust is brushed off the surface of the filter net 4 by the brush 29, the arc-shaped collecting plate 30 will maintain a certain opening angle under the action of the cleaning torsion spring 32. This will make the arc-shaped collecting plate 30 continuously contact the bristles of the brush 29, so that the dust collected on the bristles is scraped off by the arc-shaped collecting plate 30 during the rotation of the brush 29, and the fallen dust falls onto the upper surface of the arc-shaped collecting plate 30 for centralized collection. This also cleans the brush 29 and prevents the brush 29 from causing secondary pollution of dust scattering due to excessive dust accumulation during long-term work. When cleaning the dust in the arc-shaped collecting plate 30, it can be cleaned by wiping the arc-shaped collecting plate 30 from one end to the other with a wet wipe, making the cleaning of the arc-shaped collecting plate 30 very convenient; The dust-blocking plate 6 can seal the inside of the gateway body 1 when the edge gateway is not in use to prevent dust from entering. When dust needs to be cleaned, the grip 15 can be pulled to extract the dust-blocking plate 6 from the gateway body 1. During the movement of the dust-blocking plate 6, it is guided by the guide post 35 to make the movement of the dust-blocking plate 6 more stable. While the dust-blocking plate 6 is moving, the cleaning plate 33 and the scraper plate 34 at its end are pressed against the surface of the filter net 4 under the action of the compression spring 37 to scrape and clean the dust attached to the outside of the dust-blocking plate 6. When the dust-blocking plate 6 leaves the gateway body 1, the dust-blocking plate 6 can be cleaned intensively, and the space of the dust-blocking plate 6 is also opened to make it more convenient for manual maintenance of the inside of the gateway body 1. Through the above dust treatment method, the dust generated during cleaning is avoided, and the cleaned dust will fall outside the gateway body 1 to be cleaned, so that the dust will not adhere to the electrical components 3 and affect the service life of the equipment. At the same time, the edge gateway device can effectively dissipate heat and cool down during long-term use, and it is also more convenient for the device to clean dust; When the device dissipates heat, the water pump 8 is started to work. The water pump 8 pumps the coolant in the liquid storage box 23 into the heat conduction copper tube 9 through the liquid outlet pipe 26. The rotating fan 10 will generate air flow to continuously take away the temperature of the heat conduction copper tube 9 to cool it down. The heat conduction copper tube 9 is distributed in an S shape inside the gateway main body 1, which greatly increases the contact area between the heat conduction copper tube 9 and the air flow and improves the cooling efficiency of the heat conduction copper tube 9. At the same time, the S-shaped distribution of the heat conduction copper tube 9 also makes the contact area between the coolant and the heat conduction copper tube 9 larger, and the time for the coolant to be cooled by the heat conduction copper tube 9 is longer, so that the coolant passing through the heat conduction copper tube 9 can be restored to a suitable cooling temperature. This ensures that the cooling effect of the device will not decrease due to the increase in the temperature of the coolant during long-term use. Subsequently, the cooled coolant is pumped by the water pump 8 and enters the liquid inlet pipe 13 through the inside of the water pump 8. As the coolant flows, it enters the cooling pipe 14 through the liquid inlet pipe 13, and the cooling pipe 14 is cooled by the movement of the coolant in the cooling pipe 14. The cooling pipe 14 absorbs the heat generated by the circuit board 2 to achieve the cooling effect on the circuit board 2. Then the coolant passes through the cooling pipe 14 and flows back to the liquid storage box 23 through the connecting pipe 38. Subsequently, the coolant flows back into the heat conduction copper tube 9 through the liquid outlet pipe 26 again to complete a heat dissipation cycle. At the same time, the conduction tooth plate one 24 on the upper surface of the liquid storage box 23 meshes with the conduction tooth plate two 25 on the lower surface of the circuit board 2, which increases the contact area between the liquid storage box 23 and the circuit board 2, and enables the heat generated by the circuit board 2 to be quickly transferred to the liquid storage box 23 directly through the conduction tooth plate one 24 and the conduction tooth plate two 25, further improving the heat dissipation efficiency. Through the above structure, the heat dissipation effect of the device combines the advantages of air cooling and water cooling, and further improves the heat dissipation effect when the gateway body 1 is in use.
