DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] The present invention provides an intelligent distributed station terminal based on the Internet of Things architecture, such as Figures 1 to 3 As shown, it includes a ring network cabinet 1, and a common unit cabinet 2 and an interval unit cabinet 3 inside the ring network cabinet 1.

The common unit is installed in the common unit cabinet 2, and the interval unit is connected to the common unit signal. A plurality of cabinet doors 4 are arranged on the surface of the ring network cabinet 1. Among them, the interval unit has the functions of measuring, protecting, controlling and automating the power distribution of the switch, and communicates with the common unit to complete information collection and upload. The common unit is responsible for collecting information from the interval unit, and is responsible for communicating with the master station system to complete information collection and upload.

[0019] A heat dissipation frame 5 is arranged on the top of the ring network cabinet 1, a partition 6 is arranged between the bottom of the heat dissipation frame 5 and the ring network cabinet 1, and a plurality of heat dissipation grooves 7 are arranged on the surface of the partition 6. An intermediate plate 8 is arranged at the center of the heat dissipation frame 5, and the intermediate plate 8 separates the heat dissipation frame 5. Two inner grooves are formed inside the heat dissipation frame 5, and the two inner grooves of the heat dissipation frame 5 are arranged oppositely. Exhaust pipes 9 are arranged on both end surfaces of the heat dissipation frame 5. The heat generated by the common unit cabinet 2 and the interval unit cabinet 3 during operation will dissipate inside the ring network cabinet 1. When the cabinet door 4 is in a blocked state, the heat inside the ring network cabinet 1 enters the inner groove of the heat dissipation frame 5 through the plurality of heat dissipation grooves 7, and the heat inside the inner groove is discharged through the exhaust pipe 9, and the daily heat dissipation of the ring network cabinet 1 is completed by the exhaust pipe 9. When the cabinet door 4 is opened to inspect the common unit cabinet 2 and the interval unit cabinet 3, the heat inside the ring network cabinet 1 is quickly dissipated directly through the door frame of the ring network cabinet 1, and the rapid heat dissipation of the ring network cabinet 1 is completed, so as to avoid excessive temperature inside the ring network cabinet 1.

[0020] exist Figures 1 to 4In the embodiment, a filter element 10 is inserted into the exhaust pipe 9, and the outer circumferential side of the filter element 10 is fitted with the inner wall of the exhaust pipe 9. A collar 11 is sleeved on the outer side of the filter element 10, and the outer circumferential side of the filter element 10 is connected to the inner wall of the collar 11 by a plurality of connecting strips 12. The collar 11 is slidably sleeved on the outer circumferential side of the exhaust pipe 9, and the inner side of the connecting strip 12 is fitted with the end face of the exhaust pipe 9. The ends of the filter element 10 are correspondingly inserted into the exhaust pipe 9, and the collar 11 is pushed close to the exhaust pipe 9. The filter element 10 gradually enters the exhaust pipe 9 until the collar 11 is sleeved on the surface of the exhaust pipe 9. The outer end of the filter element 10 is conveniently limited by the collar 11 to prevent the filter element 10 from falling out of the exhaust pipe 9 under the push of hot air. Pull the ring 11, and the ring 11 uses the connecting strip 12 to drive the filter element 10 to be pulled out from the exhaust pipe 9, so as to facilitate the replacement of the filter element 10 that has been used for a long time, and insert the new filter element 10 into the exhaust pipe 9. The filter element 10 prevents foreign matter from entering the heat dissipation frame 5 through the exhaust pipe 9, and prevents foreign components from clogging the exhaust pipe 9.

[0021] exist Figures 5 to 7 In the figure, a push rod 13 is arranged inside the inner groove of the heat dissipation frame 5, and the end of the push rod 13 corresponds to the inner end of the exhaust pipe 9. A pushing component for pushing the push rod 13 to move is arranged inside the inner groove, and the pushing component includes a limiting ring 14, and the limiting ring 14 is sleeved on the surface of the push rod 13. A bottom plate 15 is fixed at the bottom of the limiting ring 14, and sliding sleeves 16 are arranged at both ends of the bottom plate 15. Two parallel cross bars 17 are arranged inside the inner groove, and the two sliding sleeves 16 correspond to the two cross bars 17 one by one, and the sliding sleeves 16 are sleeved on the surface of the cross bars 17. A spring 18 is sleeved on the inner side of the cross bar 17, and one end of the spring 18 is connected to the side of the middle plate 8, and the other end of the spring 18 is connected to the sliding sleeve 16, and the spring 18 is in a compressed state. The elastic force of the spring 18 makes the moving sleeve 16 slide on the surface of the cross bar 17 when the sliding sleeve 16 approaches the exhaust pipe 9. The two cross bars 17 cooperate with the two sliding sleeves 16 to limit the bottom plate 15, so that the bottom plate 15 drives the limiting ring 14 to move smoothly. At this time, the limiting ring 14 uses the pushing component to drive the push rod 13 to approach the exhaust pipe 9 until the outer end of the push rod 13 is correspondingly inserted into the exhaust pipe 9. At this time, the push rod 13 blocks the exhaust pipe 9, and multiple cabinet doors 4 close the ring network cabinet 1 to prevent outside air from directly entering the interior of the ring network cabinet 1, so that the oxygen content inside the burning ring network cabinet 1 is gradually reduced, so as to achieve the purpose of quickly extinguishing the fire of the ring network cabinet 1.

[0022] The bottom surface of the bottom plate 15 is connected with a plate 20 by using a plurality of vertical rods 19, and the vertical rods 19 pass through the heat dissipation slots 7, and the top surface of the plate 20 is in contact with the bottom surface of the partition 6, and the sliding limiting ring 14 drives the push rod 13 to move synchronously by using the pushing component. When the bottom plate 15 moves, the moving bottom plate 15 drives the plate 20 to slide on the bottom surface of the partition 6 by using the vertical rods 19, and at this time, the vertical rod 19 slides inside the heat dissipation slot 7, and the plate 20 limits the bottom of the limiting ring 14 through the plurality of vertical rods 19, and the cross bar 17 cooperates with the sliding sleeve 16 to limit the two sides of the limiting ring 14, so as to avoid the deviation in the process of the limiting ring 14 driving the push rod 13 to move synchronously.

[0023] exist Figures 5 to 8 In the figure, the pushing component also includes a slide plate 21, which is located between the bottom plate 15 and the partition 6, and the slide plate 21 is sleeved on the surface of multiple vertical rods 19. The movable pushing component uses multiple vertical rods 19 to drive the slide plate 21 to move synchronously. The bottom surface of the slide plate 21 is connected to multiple spring pieces 22, and the bottom surface of the spring pieces 22 is in contact with the top surface of the partition 6. The side of the slide plate 21 is connected to the side of the middle plate 8 by a fireproof strip 23. A dry powder belt 24 is provided on the side of the inner groove away from the middle plate 8, and the dry powder belt 24 corresponds to the slide plate 21, and the dry powder belt 24 is placed on the top surface of the partition 6. When a fire occurs inside the ring network cabinet 1, high-temperature heat enters the inner groove of the heat dissipation frame 5 through the heat dissipation groove 7. At this time, the fireproof strip 23 breaks after contacting the high-temperature heat. At this time, the fireproof strip 23 cannot continue to pull the slide plate 21, and the elastic force of the spring 18 makes the bottom plate 15 gradually approach the exhaust pipe 9. The moving exhaust pipe 9 drives the slide plate 21 to approach the dry powder belt 24 through multiple vertical rods 19 until the moving slide plate 21 impacts the surface of the dry powder belt 24. At this time, the outer end of the push rod 13 is inserted into the exhaust pipe 9, and the push rod 13 blocks the exhaust pipe 9 accordingly, and the dry powder belt 24 is broken under the action of the impact force, and the dry powder inside the dry powder belt 24 is dispersed under the impact. At this time, the dry powder inside the inner groove enters the ring network cabinet 1 through multiple heat dissipation grooves 7, and the dry powder adheres to the surface of the common unit cabinet 2 and the interval unit cabinet 3, further improving the fire extinguishing effect of the ring network cabinet 1.

[0024] The elastic force of the spring 18 causes the moving slide plate 21 to impact the surface of the dry powder belt 24. The broken dry powder belt 24 absorbs the elastic force of the spring 18 to prevent the slide plate 21 from impacting the inner wall of the heat dissipation frame 5, thereby avoiding collision damage to the heat dissipation frame 5 caused by the impact force.

[0025] A support rod 25 corresponding to the slide plate 21 is fixed to the side of the middle plate 8. An inclined portion is provided at the outer end of the support rod 25, and the slide plate 21 is slidably sleeved on the surface of the inclined portion of the support rod 25. An inclined groove 26 corresponding to the inclined portion is provided at the end of the slide plate 21. When the slide plate 21 gradually moves away from the middle plate 8 during the sliding process, the sliding slide plate 21 slides on the surface of the inclined portion using the inclined groove 26, and the slide plate 21 gradually approaches the partition 6 during the sliding process. When the slide plate 21 gradually approaches the dry powder belt 24, the slide plate 21 slides on the surface of the inclined portion of the support rod 25 using the inclined groove 26, and the slide plate 21 drives the spring piece 22 synchronously. Since the inclined portion limits the slide plate 21 using the inclined groove 26, the moving slide plate 21 cooperates with the partition 6 to squeeze the spring piece 22, and the elastic force of the spring piece 22 is used to absorb the impact force of the slide plate 21 during the sliding process, so as to avoid excessive impact force of the slide plate 21 and prevent the slide plate 21 from colliding with the inner wall of the heat dissipation frame 5.

[0026] exist Figure 5 and Figure 6 In the embodiment, the outer side of the limiting ring 14 is provided with a side plate 27, and the inner side of the outer side of the push rod 13 is provided with a side plate corresponding to the side plate 27. The outer side of the side plate is fixed with an insertion rod 28 that penetrates the side plate 27. The surface of the insertion rod 28 is sleeved with an elastic member 29, and one end of the elastic member 29 is connected to the side plate, and the other end of the elastic member 29 is connected to the side plate 27. The outer end of the insertion rod 28 is spirally sleeved with a nut 30. The movable sliding sleeve 16 moves the limiting ring 14 through the bottom plate 15. Under the elastic force of the elastic member 29, the moving limiting ring 14 drives the push rod 13 to move synchronously through the nut 30. The restriction of the end of the insertion rod 28 by the nut 30 and the elastic force of the elastic member 29 make the push rod 13 limitedly inserted inside the limiting ring 14. At this time, the moving bottom plate 15 drives the push rod 13 to move synchronously by using the limiting ring 14. When the outer end of the moving push rod 13 enters the exhaust pipe 9, the push rod 13 that continues to move gradually approaches the filter element 10 until the push rod 13 impacts the inner end of the filter element 10. At this time, the elastic member 29 absorbs the reaction force of the filter element 10 on the push rod 13, preventing the push rod 13 from rebounding to the inside of the heat dissipation frame 5 under the action of the reaction force. The push rod 13 that enters the exhaust pipe 9 always blocks the exhaust pipe 9, preventing outside air from entering the heat dissipation frame 5 through the exhaust pipe 9.

[0027] The push rod 13 impacting the filter element 10 pushes the filter element 10 to move inside the exhaust pipe 9, and the moving filter element 10 gradually moves out of the exhaust pipe 9 until the filter element 10 falls from the exhaust pipe 9. The sound of the filter element 10 falling on the ground and the filter element 10 on the ground can remind the staff. The staff can know that the temperature inside the ring network cabinet 1 is too high or that combustion has occurred inside the ring network cabinet 1, which facilitates the staff to escape from the fire scene.

[0028] Working principle of the present invention: Reference Figures 1 to 8 As shown, the heat generated by the common unit cabinet 2 and the interval unit cabinet 3 during operation will dissipate inside the ring network cabinet 1. When the cabinet door 4 is in a blocked state, the heat inside the ring network cabinet 1 enters the inner groove of the heat dissipation frame 5 through multiple heat dissipation grooves 7, and the heat inside the inner groove is discharged through the exhaust pipe 9, and the exhaust pipe 9 is used to complete the daily heat dissipation of the ring network cabinet 1. When the cabinet door 4 is opened to inspect the common unit cabinet 2 and the interval unit cabinet 3, the heat inside the ring network cabinet 1 is directly dissipated quickly through the door frame of the ring network cabinet 1, completing the rapid heat dissipation of the ring network cabinet 1 and avoiding excessive temperature inside the ring network cabinet 1.

[0029] When a fire occurs inside the ring network cabinet 1, high-temperature heat enters the inner groove of the heat dissipation frame 5 through the heat dissipation groove 7. At this time, the fireproof strip 23 breaks after contacting the high-temperature heat. At this time, the fireproof strip 23 cannot continue to pull the slide plate 21, and the elastic force of the spring 18 makes the bottom plate 15 gradually approach the exhaust pipe 9. The moving exhaust pipe 9 drives the slide plate 21 to approach the dry powder belt 24 through multiple vertical rods 19 until the moving slide plate 21 impacts the surface of the dry powder belt 24. At this time, the outer end of the push rod 13 is inserted into the exhaust pipe 9, and the push rod 13 blocks the exhaust pipe 9 accordingly, and the dry powder belt 24 is broken under the action of the impact force, and the dry powder inside the dry powder belt 24 is dispersed under the impact. At this time, the dry powder inside the inner groove enters the ring network cabinet 1 through multiple heat dissipation grooves 7, and the dry powder adheres to the surface of the common unit cabinet 2 and the interval unit cabinet 3, further improving the fire extinguishing effect of the ring network cabinet 1.

[0030] When the slide plate 21 gradually approaches the dry powder belt 24, the slide plate 21 slides on the surface of the inclined portion of the support rod 25 by means of the inclined groove 26, and the slide plate 21 drives the spring piece 22 synchronously. Since the inclined portion limits the slide plate 21 by means of the inclined groove 26, the moving slide plate 21 cooperates with the partition plate 6 to squeeze the spring piece 22, and the elastic force of the spring piece 22 is used to absorb the impact force of the slide plate 21 during the sliding process, so as to avoid excessive impact force of the slide plate 21 and prevent collision damage between the slide plate 21 and the inner wall of the heat dissipation frame 5. The elastic force of the spring 18 causes the moving slide plate 21 to impact on the surface of the dry powder belt 24, and the broken dry powder belt 24 is used to absorb the elastic force of the spring 18, so as to prevent the slide plate 21 from impacting on the inner wall of the heat dissipation frame 5 and prevent collision damage between the heat dissipation frame 5 and the heat dissipation frame 5 due to the impact force.

[0031] When the outer end of the moving push rod 13 enters the exhaust pipe 9, the push rod 13 that continues to move gradually approaches the filter element 10 until the push rod 13 impacts the inner end of the filter element 10. At this time, the elastic member 29 absorbs the reaction force of the filter element 10 on the push rod 13, preventing the push rod 13 from rebounding to the inside of the heat dissipation frame 5 under the action of the reaction force. The push rod 13 that enters the exhaust pipe 9 always blocks the exhaust pipe 9, preventing outside air from entering the heat dissipation frame 5 through the exhaust pipe 9.

[0032] The push rod 13 impacting the filter element 10 pushes the filter element 10 to move inside the exhaust pipe 9, and the moving filter element 10 gradually moves out of the exhaust pipe 9 until the filter element 10 falls from the exhaust pipe 9. The sound of the filter element 10 falling on the ground and the filter element 10 on the ground can remind the staff. The staff can know that the temperature inside the ring network cabinet 1 is too high or that combustion has occurred inside the ring network cabinet 1, which facilitates the staff to escape from the fire scene.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
