Description

Technical Field

[0001] The present invention relates to the field of heat dissipation of electrical appliances, and in particular to an intelligent temperature control system for communication network engineering. Background Art

[0002] Network communication equipment generates significant heat during use. During communications project construction, multiple devices are often placed in the same electrical cabinet for easier centralized management. However, this can also cause the cabinet's temperature to rise rapidly. If heat isn't dissipated promptly, this not only impacts network communication reliability but can also cause fires. Temperature control systems are now commonly incorporated into communications equipment, but these systems rely on air cooling. While this simple cooling method can be detrimental, if a fire breaks out due to excessively high wiring temperatures, the wind can fuel the fire, and delaying wind shutoff can have negative consequences.

[0003] Furthermore, when using air cooling, dust in the air can accumulate on the surfaces of communication equipment and wires. This dust accumulation can also affect the proper heat dissipation of the equipment, leading to localized overheating. Therefore, this solution proposes an intelligent temperature control system for communication network engineering. Summary of the Invention

[0004] The intelligent temperature control system for communication network engineering proposed in the present invention solves the problems in the prior art of communication network engineering temperature control systems that are unable to promptly cut off wind power transmission and extinguish the fire when a line catches fire, and are inconvenient to remove dust attached to the surface of the equipment.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A cabinet body, wherein N partitions are fixed horizontally inside the cabinet body, and the N partitions divide the interior of the cabinet body into N+1 placement spaces, a PLC controller is installed on the outer wall of the cabinet body, and a mounting plate is movably mounted on the bottom of the placement space through a fixing piece;

[0008] The heat dissipation mechanism includes a fixed cover fixed to the outer wall of one side of the cabinet, a plurality of blowers installed on the outer wall of the fixed cover, and a plurality of temperature sensors respectively installed on the top of the plurality of placement spaces. The air outlets of the plurality of blowers are all fixed with air inlet pipes, and the plurality of air inlet pipes are respectively connected to the plurality of placement spaces. The temperature sensors and the blowers are both connected to a PLC controller.

[0009] The fire extinguishing mechanism includes a placement frame fixed to the side wall of the fixed cover, a carbon dioxide storage tank placed in the placement frame, a smoke sensor installed at the top of the placement space, a delivery pipe fixed to the inner wall of one side of the fixed cover, and a linkage assembly installed on the cabinet for delivering gas from the carbon dioxide storage tank to the delivery pipe in the event of a line fire. Multiple air inlet pipes are connected to the delivery pipe through branch pipes, and the smoke sensor is connected to the PLC controller.

[0010] The dust removal mechanism includes multiple air ducts respectively installed on the top of multiple placement spaces, multiple main pipes installed on the bottom of the air ducts through connectors, a powerful fan installed on the top of the fixed cover, and a driving assembly installed inside the fixed cover for driving the multiple main pipes to swing and the multiple mounting plates to vibrate at the same time. The multiple air ducts are all connected to the air outlet of the powerful fan.

[0011] Through the above technical solution, not only can the purpose of intelligent temperature control and fire extinguishing be achieved, but also the dust attached to the surface of the communication equipment can be conveniently removed, thereby avoiding the phenomenon of uneven heat dissipation of the communication equipment and ensuring the stable operation of the communication equipment.

[0012] As a further improvement of the above scheme, the linkage assembly includes a piston cylinder fixed on the outer wall of the cabinet body and having an opening at the bottom, a feed pipe fixed on the top of the piston cylinder and a connecting pipe fixed on the outer periphery of the feed pipe, the feed pipe is equipped with a solenoid valve electrically connected to the PLC controller, and the top of the feed pipe is equipped with a pipe joint for connecting to the outlet pipe of the carbon dioxide storage tank, the feed pipe is also equipped with a one-way valve located on the side of the connecting pipe away from the solenoid valve, the connecting pipe is equipped with a valve, and one end of the valve stem of the valve is fixed with a linkage gear, the other end of the connecting pipe extends to the inside of the fixed cover and is fixed and connected with the delivery pipe, an exhaust pipe is fixed on the top of the piston cylinder, a manual valve is installed on the exhaust pipe, a piston is movably installed in the piston cylinder, a piston rod is fixed to the bottom surface of the piston, and the bottom of the piston rod extends to the outside of the piston cylinder, and a linkage rack meshing with the linkage gear is fixed to the outer periphery of the piston rod.

[0013] Through the above technical solution, carbon dioxide can be delivered to the storage space in time when a fire occurs, thereby isolating the air and achieving the purpose of fire extinguishing.

[0014] As a further improvement of the above scheme, the connecting part includes a rotating shaft rotatably connected to the bottom surface of the air duct and a connecting block fixed on the outer periphery of the rotating shaft. The main pipe is fixed at one end of the connecting block, a fixed gear is fixed at one end of the rotating shaft, and multiple nozzles are installed on the bottom surface of the main pipe.

[0015] Through the above technical solution, the main pipe can rotate with the rotating shaft as the rotation center, so that the nozzle can blow air in different directions.

[0016] As a further improvement of the above-mentioned scheme, the driving assembly includes a transmission shaft rotatably connected to the inner wall of the fixed cover, a transmission member 1 installed inside the fixed cover for driving multiple mounting plates to vibrate, and a transmission member 2 for driving multiple main pipes to swing simultaneously. The transmission shaft is connected to the connecting member 1 and the connecting member 2, and a motor for driving the transmission shaft to rotate is installed inside the fixed cover.

[0017] By means of the above technical solution, the main pipe can be driven to rotate back and forth while the mounting plate can be driven to vibrate back and forth.

[0018] As a further improvement of the above scheme, the outside of the transmission shaft is sleeved with a driving gear 1 and a driving gear 2, and the transmission member 1 includes a fixed shaft 1 rotatably connected to the inner wall of the fixed cover, a connecting gear 1 fixed to the top of the fixed shaft 1, and a connecting rod fixed to the outer wall of the mounting plate close to the fixed cover. The connecting gear 1 is engaged with the driving gear 1, and a connecting rod 1 is hinged at a position where the top surface of the connecting gear 1 deviates from the center of the circle, and the other end of the connecting rod 1 is hinged to a connecting plate 1. The other end of the connecting rod extends to the inside of the fixed cover and is fixed to the outer wall of the connecting plate 1.

[0019] Through the above technical solution, the connecting gear 1 can be driven to rotate when the rotating shaft rotates, and then the connecting plate 1 can be driven to move back and forth, ultimately achieving the purpose of driving multiple mounting plates to vibrate back and forth.

[0020] As a further improvement of the above scheme, the transmission member 2 includes a fixed shaft 2 rotatably connected to the inner wall of the fixed cover, a connecting gear 2 fixed on the top of the fixed shaft 2 and a plurality of movable racks movably connected to the tops of the plurality of placement spaces respectively. A connecting rod 2 is hingedly connected to the top surface of the connecting gear 2 at a position deviating from the center of the circle, and a connecting plate 2 is hingedly connected to the other end of the connecting rod 2. The movable rack in the same placement space is located at the top of the plurality of fixed gears in the placement space, and the movable rack is meshed with the fixed gear. One end of the plurality of movable racks extends to the inside of the fixed cover and is fixedly connected to the outer wall of the connecting plate 2.

[0021] Through the above technical solution, the transmission shaft can be used to drive the connecting gear 2 to rotate, thereby ultimately achieving the purpose of driving multiple movable racks to move back and forth. After the movable racks move, they will drive the main pipe to rotate, thereby changing the air outlet direction of the nozzle.

[0022] As a further improvement of the above scheme, a protective door is installed on the front of the cabinet, and a protective frame is installed on the back of the cabinet. Multiple heat dissipation holes 1 are provided on the long sides of both sides of the protective frame. Side panels that can be moved up and down are installed on the outer walls of the long sides of both sides of the protective frame through mounting parts. Heat dissipation holes 2 corresponding to heat dissipation holes 1 are provided on both side panels. The tops of the two side panels are fixed by a fixing plate. A lever is hinged on the outer wall of one side of the protective frame. The long end of the lever is slidably connected to the bottom of the piston rod, and the short end of the lever is slidably connected to the outer wall of one of the side panels.

[0023] Through the above technical solution, the setting of the protective frame creates a relatively closed environment near the wiring area of ​​the communication equipment. When a fire occurs inside the cabinet, the protective frame is closed to reduce air circulation, so that a large amount of outside air will not enter the inside of the protective frame, thereby preventing the wires in the wiring area from burning.

[0024] As a further improvement of the above-mentioned solution, the interior of the protective frame is fixed with a plurality of dividing bars arranged along its width direction, and the number of dividing bars is the same as the number of partitions. The dividing bars divide the inside of the protective frame into a plurality of wiring areas, and the upper part of each wiring area is rotatably connected to a mounting shaft arranged along the width direction of the protective frame. A cover plate is fixed to the outer periphery of the mounting shaft, and both ends of the mounting shaft extend to the outside of both sides of the protective frame and are fixed with transmission gears. A plurality of tooth grooves meshing with the transmission gears are provided on one long side of the two side plates. When the cover plate is closed in the wiring area, a gap of 1-2 cm is provided between the bottom of the cover plate and the bottom of the wiring area.

[0025] Through the above technical solution, under normal circumstances, the cover is in an open state to facilitate the dissipation of heat inside the protective frame. When a fire occurs, the cover can be automatically closed, thereby effectively reducing the air circulation speed inside and outside the protective frame, so that the air inside the protective frame can be quickly discharged when carbon dioxide enters, thereby preventing the wiring from catching fire.

[0026] As a further improvement of the above-mentioned solution, the top surface of the partition and the bottom inner wall of the cabinet are provided with installation grooves arranged along the width direction of the cabinet. The fixing part includes a limit rod fixed in the installation groove and a limit sleeve movable on the outside of the limit rod. The top of the limit sleeve is fixedly connected to the bottom surface of the mounting plate. The outer movable sleeve of the limit rod is provided with two springs, and the two springs are respectively located at the two ends of the limit sleeve.

[0027] The above technical solution ensures that the mounting plate can move left and right, and the setting of the spring also helps to adjust the position of the mounting plate in the placement space so that the mounting plate will not be too far to the left or right.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Through the setting of the heat dissipation mechanism and the fire extinguishing mechanism, the equipment inside the cabinet can be cooled by the blower under normal heat dissipation conditions. When a fire point appears inside the cabinet, the blower stops working and the solenoid valve opens. The carbon dioxide in the carbon dioxide storage tank enters the multiple placement spaces through the air inlet pipe, so that the placement spaces are filled with carbon dioxide, thereby achieving the purpose of cooling and fire extinguishing.

[0030] 2. Through the setting of the dust removal mechanism, the motor can be started at the same time as the powerful fan is started, so that when the strong wind is ejected from the nozzle, the main pipe can swing back and forth continuously, so that the nozzle can continuously change the direction of the wind, so as to better blow away the dust on the surface of the equipment and wires in the placement space. At the same time, the continuous back and forth vibration of the mounting plate further enhances the falling of dust on the surface of the equipment and the surface of the wires.

[0031] 3. Through the coordination among the protective frame, side panels, lever, piston cylinder, installation and cover plate, when the equipment in the placement space catches fire, the piston rod can be moved downward to drive the two side panels to move upward at the same time, so that the second heat dissipation hole on the side panel and the first heat dissipation hole on the protective frame are staggered, thereby achieving the purpose of blocking the first heat dissipation hole. While the side panel rises, it drives the installation shaft to rotate counterclockwise, so that the cover plate is lowered to cover the wiring area, avoiding air circulation. After the carbon dioxide escaped in the placement space enters the protective frame, it can quickly empty the oxygen inside the protective frame, thereby achieving the purpose of extinguishing the fire and avoiding the burning of the wiring.

[0046] The heat dissipation mechanism includes a fixed cover 6 fixed on the outer wall of one side of the cabinet 1, a plurality of blowers 28 installed on the outer wall of the fixed cover 6, and a plurality of temperature sensors 30 respectively installed on the top of the plurality of placement spaces. The air outlets of the plurality of blowers 28 are fixed with air inlet pipes 8, and the plurality of air inlet pipes 8 are respectively connected to the plurality of placement spaces. The temperature sensor 30 and the blower 28 are both connected to the PLC controller. When the temperature sensor 30 detects a temperature change in the placement space, it will transmit a signal to the PLC controller. The PLC controller then controls the power of the blower 28, thereby controlling the size of the heat dissipation wind. A plurality of ventilation holes connected to the interior of the cabinet 1 are provided on the outer wall of the cabinet 1 away from the fixed cover.

[0047] The fire extinguishing mechanism includes a placement frame 10 fixed on the side wall of the fixed cover 6, a carbon dioxide storage tank 7 placed in the placement frame 10, a smoke sensor 31 installed on the top of the placement space, a delivery pipe 9 fixed on the inner wall of one side of the fixed cover 6, and a linkage component installed on the cabinet 1 for delivering the gas in the carbon dioxide storage tank 7 to the delivery pipe 9 when the line is on fire.

When the smoke sensor 30 detects smoke in the storage space, it will transmit a signal to the PLC controller, and the PLC controller determines that there is a fire in the storage space, thereby immediately shutting down the blower 28 and opening the solenoid valve. When the valve is opened, the gas in the carbon dioxide storage tank 7 enters the piston cylinder 11 through the feed pipe 17 first, so that the piston descends and drives the piston rod 22 and the linkage rack 24 to descend synchronously. The linkage rack 24 descends and drives the linkage gear 19 to rotate, thereby opening the valve. After that, the carbon dioxide gas in the feed pipe 17 enters the delivery pipe 9 through the connecting pipe, and finally the carbon dioxide gas enters the multiple placement spaces through multiple air inlet pipes 8 respectively, thereby discharging the air in the placement space and filling the placement space with carbon dioxide, thereby achieving the purpose of extinguishing the fire.

[0048] The dust removal mechanism includes a plurality of air ducts 45 respectively installed on the top of a plurality of placement spaces, a plurality of main pipes 33 installed on the bottom of the air ducts 45 through connectors, a powerful fan 26 installed on the top of the fixed cover 6, and a driving assembly installed inside the fixed cover 6 for driving the plurality of main pipes 33 to swing and the plurality of mounting plates 35 to vibrate.

The main pipe 33 is fixed to one end of the connecting block, and a fixed gear 32 is fixed to one end of the rotating shaft 46. A plurality of nozzles are installed on the bottom of the main pipe 33. The arrangement of the connector allows the main pipe 33 to swing with the rotating shaft 46 as the rotation center, so that the nozzles can blow air in different directions. The wind ejected from the nozzles is used to blow away the dust on the surface of the equipment or the surface of the wires and wiring to prevent the adhesion of dust from affecting the normal heat dissipation of the equipment.

[0049] The driving assembly includes a transmission shaft 41 rotatably connected to the inner wall of the fixed cover 6, a transmission member 1 installed inside the fixed cover 6 for driving multiple mounting plates 35 to vibrate, and a transmission member 2 for driving multiple main pipes 33 to swing simultaneously. The transmission shaft 41 is transmission-connected to the connecting member 1 and the connecting member 2. A motor for driving the transmission shaft 41 to rotate is installed inside the fixed cover 6. The outer sleeve of the transmission shaft 41 is provided with a driving gear 1 40 and a driving gear 2 42. The transmission member 1 includes a fixed shaft 1 44 rotatably connected to the inner wall of the fixed cover 6, a connecting gear 1 39 fixed on the top of the fixed shaft 1 44, and a connecting rod 50 fixed on the outer wall of the mounting plate 35 near the fixed cover 6. The connecting gear 1 39 is meshed with the driving gear 1 40, and a connecting rod 1 37 is hinged at a position where the top surface of the connecting gear 1 39 deviates from the center of the circle. The other end of the connecting rod 1 37 is hinged to a connecting plate 1 29. The other end of the connecting rod 50 extends to the inner side of the fixed cover 6 and is fixed to the outer wall of the connecting plate 1 29. The transmission member 2 includes a rotating connecting The fixed shaft 2 on the inner wall of the fixed cover 6, the connecting gear 2 43 fixed on the top of the fixed shaft 2 and the multiple movable racks 34 respectively movably connected to the tops of the multiple placement spaces, the top surface of the connecting gear 2 43 is hinged with a connecting rod 2 38 at a position deviating from the center of the circle, and the other end of the connecting rod 2 38 is hinged with a connecting plate 2 36. The movable rack 34 in the same placement space is located at the top of the multiple fixed gears 32 in the placement space, and the movable rack 34 is meshed with the fixed gear 32. One end of the multiple movable racks 34 extends to the inside of the fixed cover 6 and is fixedly connected to the outer wall of the connecting plate 2 36. After the motor rotates, it drives the transmission shaft 41 to rotate. After the transmission shaft 41 rotates, it will drive the connecting gear 1 39 and the connecting gear 2 43 to rotate at the same time. After the connecting gear 1 39 and the connecting gear 2 43 rotate, they will respectively drive the connecting plate 1 29 and the connecting plate 2 36 to move back and forth along the width direction of the cabinet 1, and finally it can achieve the purpose of driving the main pipe 33 to rotate back and forth and the mounting plate 35 to vibrate back and forth.

[0050] The working principle of this embodiment is as follows: when the communication equipment inside the cabinet 1 is operating normally, the blowers 28 are in operation, and the air blown by the multiple blowers 28 enters the multiple storage spaces through the multiple air inlet pipes 8, thereby cooling the communication equipment in the storage spaces. When the temperature sensor detects a change in the temperature of the storage space, it transmits a signal to the PLC controller, which controls the corresponding blower and adjusts its power, thereby increasing the power when the temperature is high and reducing the power when the temperature is low.

[0051] When the smoke sensor 30 detects smoke in the storage space, it will transmit a signal to the PLC controller. The PLC controller determines that there is a fire in the storage space, and immediately shuts down the blower 28 and opens the solenoid valve at the same time. The gas in the carbon dioxide storage tank 7 enters the piston cylinder 11 through the feed pipe 17 first, so that the piston descends and drives the piston rod 22 and the linkage rack 24 to descend synchronously. The descending linkage rack 24 drives the linkage gear 19 to rotate, thereby opening the valve. Thereafter, the carbon dioxide gas in the feed pipe 17 enters the delivery pipe 9 through the connecting pipe, and finally the carbon dioxide gas enters the multiple storage spaces through the multiple air inlet pipes 8 respectively, thereby discharging the air in the storage space and filling the storage space with carbon dioxide, thereby achieving the purpose of fire extinguishing. After the fire extinguishing is completed, the solenoid valve is closed under the control of the PLC controller, and then the manual valve on the exhaust pipe 20 is opened, and the piston rod 22 is lifted up again to restore it to its original position. The valve will also be closed again during the upward movement of the piston rod 22.

[0052] When it is necessary to clean the dust on the surface of the communication equipment and the dust on the wiring, the motor can be started. After the motor rotates, it drives the transmission shaft 41 to rotate. After the transmission shaft 41 rotates, it drives the connecting gear 1 39 and the connecting gear 2 43 to rotate at the same time. After the connecting gear 1 39 rotates, it drives the connecting plate 1 29 to move back and forth, thereby causing the multiple movable racks 34 to move back and forth. After the movable racks move back and forth, they drive the fixed gear 32 to rotate back and forth, thereby causing the main pipe 33 to rotate back and forth with the rotating shaft as the rotation center line, thereby changing the air outlet direction of the nozzle. After the connecting gear 2 43 rotates, it drives the connecting plate 2 36 to move back and forth along the width direction of the cabinet 1. After the connecting plate 2 36 moves back and forth, it drives the mounting plate to move back and forth, thereby achieving the effect of vibrating the mounting plate 35, thereby further accelerating the falling of dust on the white surface of the communication equipment and dust on the surface of the wires.

[0053] Example 2

[0054] Combine Figure 1-3 and Figure 7Based on Example 1, this embodiment is further improved in that: a protective door is installed on the front of the cabinet 1, a protective frame 2 is installed on the back of the cabinet 1, a plurality of heat dissipation holes are opened on the long sides of both sides of the protective frame 2, and side panels 3 that can be moved up and down are installed on the outer walls of the long sides of both sides of the protective frame 2 through mounting parts. The mounting parts include a sleeve rod 15 fixed on the side wall of the protective frame 2 and a sleeve 16 movably sleeved on the outside of the sleeve rod 15, and the sleeve 16 is fixed to the outer wall of the side panel 3.

[0055] The two side panels 3 are each provided with a heat dissipation hole 2 corresponding to the heat dissipation hole 1. When the heat dissipation hole 1 is aligned with the heat dissipation hole 2, the space outside the side protection frame 2 can enter the heat dissipation hole 1 through the heat dissipation hole 2 and then enter the inside of the protection frame 2, so that the air inside and outside the protection frame 2 can be exchanged, which is convenient for the heat dissipation inside the protection frame 2. When the heat dissipation hole 2 is completely staggered with the heat dissipation hole 1, the heat dissipation hole 1 is blocked, reducing the circulation speed of the air inside and outside the protection frame 2. The tops of the two side panels 3 are fixed by a fixing plate. A lever 12 is hinged on the outer wall of one side of the protection frame 2. The long end of the lever 12 is slidably connected to the bottom of the piston rod 22, and the short end of the lever 12 is slidably connected to the outer wall of one of the side plates 3. The lever 12 is a force-saving lever. A slide groove 14 is provided along its length on the short end of the lever 12, and a slide groove 23 is provided along its length on the long end of the lever 12. A fixing column 13 is fixed on the outer wall of the side plate 3, and one end of the fixing column 13 extends into the slide groove 14 and slides with the slide groove 14. A fixing column 2 is fixed on the outer wall of the piston rod 22, and one end of the fixing column 2 extends into the slide groove 23 and slides with the slide groove 23.

[0056] The inside of the protective frame 2 is fixed with multiple dividing bars arranged along its width direction. The number of dividing bars is the same as the number of partitions 27. The dividing bars divide the inside of the protective frame 2 into multiple wiring areas, and the upper part of each wiring area is rotatably connected to the installation shaft 25 arranged along the width direction of the protective frame 2. The outer periphery of the installation shaft 25 is fixed with a cover plate 5. The two ends of the installation shaft 25 extend to the outside of both sides of the protective frame 2 and are fixed with a transmission gear 4. A plurality of tooth grooves that mesh with the transmission gear 4 are provided on the long sides of one side of the two side plates 3. When the cover plate 5 is closed in the wiring area, a gap of 1-2 cm is provided between the bottom of the cover plate 5 and the bottom of the wiring area. The gap is set to leave space for the wiring to avoid the wiring being pressed after the cover plate 5 is closed.

[0057] The working principle of this embodiment is as follows: when a fire occurs inside the cabinet 1, the carbon dioxide in the carbon dioxide storage tank 7 will first enter the piston cylinder 11, thereby causing the piston plate and piston rod 22 to descend. After the piston plate descends, it drives the lever 12 to rotate, causing the long end of the lever 12 to descend and the short end to rise. After the short end of the lever 12 rises, it drives the two side panels 3 to move upward at the same time, thereby completely offsetting the heat dissipation hole 2 on the side panel 3 from the heat dissipation hole 1 on the protective frame 2. At the same time, after the side panel 3 moves upward, it drives the transmission gear 4 to rotate counterclockwise, thereby causing the originally opened cover plate 5 to gradually close until the cover plate 5 completely covers the wiring area, thereby reducing the air exchange rate inside the protective frame 2. The carbon dioxide in the cabinet 1 will then enter the inside of the protective frame 2, further exhausting the oxygen in the protective frame 2, thereby effectively preventing the wiring from catching fire. After the fire is extinguished, with the manual valve on the exhaust pipe 20 open, the two side panels 3 can be directly pressed downward to restore the side panels 3 and the piston rod 22 to their original positions.

Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
