Description

Technical Field

[0001] The present invention relates to the technical field of ring main unit, and in particular to an energy-saving ring main unit with intelligent temperature control and a temperature control method thereof. Background Art

[0002] Ring main unit is a special type of switch cabinet, which is optimized for ring network power supply. That is, compared with the application scenario of standard switch cabinet, it does not require complex protection functions and has high power supply reliability requirements. The internal temperature control of the existing ring main unit is the key link to ensure its stable operation, reduce failure rate and increase service life. During high-load operation, the temperature of internal circuit breakers, cable connectors and other parts can reach above 80°C, which accelerates insulation aging. Local hot spots are prone to discharge and short circuit, leading to equipment failure. The existing temperature control method is mainly through passive heat dissipation design (such as heat dissipation holes and heat sinks in the cabinet), temperature monitoring (such as temperature sensors arranged at multiple points in the cabinet, etc.) and active control (such as starting or regulating forced ventilation, refrigeration, heat pipe radiators, circulating liquid cold plates and other heat dissipation close to heating elements in the cabinet when abnormal temperature is detected) The method is implemented. In the prior art, such as the intelligent ring network cabinet cable temperature monitoring device and the intelligent ring network cabinet disclosed in the Chinese patent document CN115149407A, and the air-insulated intelligent vacuum ring network cabinet disclosed in CN207947548U, all adopt the above-mentioned similar combined temperature control method. However, no matter which active temperature control device or method is used, if it is placed separately on various parts or components in the cabinet, it is more troublesome to independently install and operate multiple devices, and the active temperature control position is not flexible enough and it is difficult to cover the temperature control of the entire cabinet. If an integrated active temperature control device is simply arranged in the cabinet, although it can cover the temperature control of the entire cabinet and the overall control is more convenient, if only a local area or component in the cabinet has abnormal temperature, there is a problem of low efficiency of individual temperature control for various parts or components in the cabinet. Summary of the invention

[0003] In view of this, the purpose of the present invention is to propose an energy-saving ring main unit with intelligent temperature control and a temperature control method thereof, so as to solve the problem that it is difficult for the existing ring main unit to take into account the advantages and disadvantages of both overall active regulation and local independent active regulation of each part or component when controlling its internal temperature, so as to achieve further intelligent energy-saving temperature control effect.

The temperature averaging plate is designed as a hollow structure. The top and bottom ends of the temperature averaging plate are designed as open structures. Multiple fans are arranged horizontally at the top opening of the temperature averaging plate. A guide rail is vertically arranged on the inner wall of the ring network cabinet beside the temperature plate, a detection slider is slidably connected to the guide rail, a temperature measuring component is arranged on the detection slider, a plurality of monitoring positions are arranged in sequence from top to bottom on the guide rail, a telescopic component is connected to the side end of the detection slider facing the temperature plate, and the telescopic component is in an initial contracted state; A plurality of horizontally arranged heat conducting plates are arranged from top to bottom in the temperature equalizing plate, and the upper and lower adjacent heat conducting plates are respectively close to different left and right sides of the temperature equalizing plate, and the plane direction of each heat conducting plate is in an initial position parallel to the plane direction of the temperature equalizing plate, and a rotating shaft is connected to the end of the heat conducting plate, and the rotating shaft is rotatably connected to the inner side of the ring network cabinet, and one end of the rotating shaft passes through the temperature equalizing plate and is connected to a positioning part, which is correspondingly located on the side of the monitoring position. When the detection slider slides to the interval on one side of the positioning part, if the temperature measuring component detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic component is triggered to be extended, and the detection slider continues to slide, and the positioning part is driven to rotate by the extended telescopic component, so that the plane direction of the heat conducting plate is rotated to a vertical position perpendicular to the plane direction of the temperature equalizing plate, and the fan power is triggered to be increased at the same time.

[0005] Preferably, the front and rear sides of the vertical heat conducting plate are respectively pressed against the front and rear sides of the temperature averaging plate.

When the heat conducting plate is rotated to the initial position or the vertical position, the limiting block penetrates into the limiting groove for limitation.

[0008] Preferably, a filter cartridge is rotatably connected to the bottom opening of the temperature equalizing plate, and a barrel shaft is connected to the end of the filter cartridge. The barrel shaft is rotatably connected to the inner side of the temperature equalizing plate, and one end of the barrel shaft passes through the temperature equalizing plate and is connected to a connecting rod.

[0010] Preferably, when the detection slider slides again to the monitoring position where the monitored temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, if the temperature monitored by the temperature measuring component is less than the calibration value, the telescopic component is triggered to extend and the fan power is reduced.

[0011] Preferably, the heat conducting plates are arranged in groups of two, and the two heat conducting plates in the group are transmission connected.

If the temperature measuring component detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic component is triggered to extend, and the detection slider continues to slide. The extended telescopic component drives the positioning part to rotate, so that the plane direction of the heat conduction plate rotates to a vertical position perpendicular to the plane direction of the temperature equalizing plate, and at the same time triggers the increase of the fan power, so as to realize adaptive temperature control of the local temperature abnormality area.

[0013] Preferably, the heat conducting plates are arranged in groups of two, and when the detection slider intermittently slides to the first heat conducting plate in the group, if the temperature measuring component monitors that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic component is triggered to be partially extended, until the detection slider intermittently slides to the second heat conducting plate in the group, if the temperature measuring component monitors that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic component is triggered to continue to extend to a fully extended state, driving the positioning part to rotate, driving the two heat conducting plates in the group to rotate synchronously, and triggering to increase the fan power; if only one of the heat conducting plates in the group monitors that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, an abnormal monitoring report is sent.

[0020] like Figure 1 , Figure 2As shown, an energy-saving ring network cabinet with intelligent temperature control comprises a ring network cabinet body 1, a temperature averaging plate 2 is attached to the inner wall of the ring network cabinet body 1, the temperature averaging plate 2 is designed as a hollow structure, the top and bottom ends of the temperature averaging plate 2 are designed as open structures, and a plurality of fans 3 are arranged horizontally at the top opening of the temperature averaging plate 2, a guide rail 4 is vertically arranged on the inner wall of the ring network cabinet body 1 beside the temperature averaging plate 2, a detection slider 5 is slidably connected to the guide rail 4, a temperature measuring component 6 is arranged on the detection slider 5, a plurality of monitoring positions are arranged in sequence from top to bottom on the guide rail 4, a telescopic component 7 is connected to the side end of the detection slider 5 facing the temperature averaging plate 2, the telescopic component 7 is in an initial contracted state, a plurality of horizontally arranged heat conducting plates 8 are arranged from top to bottom in the temperature averaging plate 2, and the upper and lower adjacent heat conducting plates 8 are respectively close to the temperature averaging plate 2. At different left and right sides of the temperature plate 2, the plane direction of each heat conduction plate 8 is in an initial position parallel to the plane direction of the temperature plate 2. The end of the heat conduction plate 8 is connected to a rotating shaft 9, which is rotatably connected to the inner side of the ring network cabinet. One end of the rotating shaft 9 passes through the temperature plate 2 and is connected to a positioning part 10. The positioning part 10 is correspondingly located on the side of the monitoring position. When the detection slider 5 slides to the interval on one side of the positioning part 10, if the temperature measuring part 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic part 7 is triggered to be extended, and the detection slider 5 continues to slide. The positioning part 10 is driven to rotate by the extended telescopic part 7, so that the plane direction of the heat conduction plate 8 is rotated to a vertical position perpendicular to the plane direction of the temperature plate 2, and the power of the fan 3 is triggered to be increased.

[0021] The present invention is based on the existing structural principle of the ring network cabinet, and a temperature averaging plate 2 is attached to the inner wall of the ring network cabinet body 1, wherein the temperature averaging plate 2 can be optionally arranged on the inner wall of the back of the ring network cabinet body 1, which does not affect the front door opening, and the components in the cabinet are installed closely against the temperature averaging plate 2 from top to bottom. The temperature averaging plate 2 is made of existing materials with high thermal conductivity. In particular, the temperature averaging plate 2 is designed with a hollow structure, and the top and bottom ends of the temperature averaging plate 2 are designed with an open structure. The bottom opening of the temperature averaging plate 2 is designed as an air inlet, and a plurality of fans 3 are arranged horizontally at the top opening of the temperature averaging plate 2 for exhausting air upwards, such as Figure 1 As shown, a straight air outlet channel from bottom to top is formed in the temperature averaging plate 2, so that natural ventilation inside the temperature averaging plate 2 and heat dissipation exposed on the back of the temperature averaging plate 2 are utilized to form an integrated passive temperature control design for the ring network cabinet 1 and the components in the cabinet. Active temperature control is required. For example, during active heat dissipation, the heat in the ring network cabinet 1 and the components in the cabinet is transferred to the temperature averaging plate 2. By turning on the fan 3 to exhaust air upward and adjusting the power of the fan 3, the hot air in the temperature averaging plate 2 is accelerated to be continuously discharged upward, forming an integrated efficient active temperature control design. In addition, in the temperature control design, the dust in the air intake will not directly enter the ring network cabinet 1, thereby avoiding the dust impact on the ring network cabinet. At the same time, a guide rail 4 is vertically provided on the inner wall of the ring network cabinet 1, which is located next to the temperature equalizing plate 2. A detection slider 5 is slidably connected to the guide rail 4, and a temperature measuring component 6 is provided on the detection slider 5. A plurality of monitoring positions are arranged in sequence from top to bottom on the guide rail 4. A telescopic component 7 is connected to the side end of the detection slider 5 facing the temperature equalizing plate 2, and the telescopic component 7 is in an initial contracted state. Specifically, the temperature measuring component 6 can adopt existing conventional temperature sensors and other components, and the telescopic component 7 can adopt existing conventional components such as electric elastic telescopic rods. A linear motor structure can be adopted in the guide rail 4, that is, an existing conventional motor drives the lead screw to rotate, and then The detection slider 5 meshing with the lead screw is driven to slide vertically and linearly. The lead screw can use an existing reciprocating lead screw component, and the start and stop time of the motor is actively set, or existing conventional components such as photoelectric sensors are arranged at each monitoring position to detect the position of the detection slider 5 and trigger the motor to stop intermittently, thereby driving the detection slider 5 to slide up and down in an intermittent reciprocating manner. During the intermittent time when the detection slider 5 moves to the monitoring position, the temperature measuring component 6 is triggered to start temperature measurement, thereby eliminating the need to repeatedly arrange multiple temperature sensors for temperature measurement in the cabinet, and realizing comprehensive temperature monitoring with flexible and adjustable positions; In particular, a plurality of horizontally arranged heat conducting plates 8 are arranged from top to bottom in the temperature homogenizing plate 2, such as Figure 1As shown, the upper and lower adjacent heat conducting plates 8 are respectively close to the left and right sides of the temperature averaging plate 2, and the plane direction of each heat conducting plate 8 is parallel to the initial orientation of the plane direction of the temperature averaging plate 2. The end of the heat conducting plate 8 is connected with a rotating shaft 9, and the rotating shaft 9 is rotatably connected to the inner side of the ring network cabinet. One end of the rotating shaft 9 passes through the temperature averaging plate 2 and is connected with a positioning part 10. The positioning part 10 is located next to the monitoring position. Optionally, the part of the rotating shaft 9 located in the temperature averaging plate 2 can be designed as a thin rod to avoid affecting the air outlet. The heat conducting plate 8 is With the flattened design, when the plane direction of each heat conducting plate 8 is parallel to the initial orientation of the plane direction of the temperature averaging plate 2, the overall heat dissipation from bottom to top in the temperature averaging plate 2 is not greatly affected. The part of the rotating shaft 9 located outside the temperature averaging plate 2 can be designed as a thick rod, which is conducive to the stable connection of the positioning part 10 and driving the heat conducting plate 8 to rotate as a whole. The rotating connection of the rotating shaft 9 can adopt the existing conventional shaft sealing methods such as oil seals, bearing seals, packing seals, etc., and even if there is a small amount of air leakage at the rotating connection, it will not affect the overall heat dissipation of the temperature averaging plate 2. When the detection slider 5 slides to the monitoring position, that is, the interval on one side of the positioning part 10, if the temperature measuring component 6 detects that the temperature at this lateral position is greater than the temperature threshold or the temperature change rate (the temperature rise rate of the same monitoring position) is greater than the speed change threshold, the telescopic component 7 is triggered to be extended, wherein the temperature value detected by the temperature measuring component 6 at each monitoring position will be recorded in the historical data list, which is convenient for comparing the temperature change rate of the same monitoring position. Specifically, a microcontroller such as the existing conventional microcontroller connected to the temperature sensor can be used, and the display connected to the microcontroller can be used for display and control. As the detection slider 5 continues to slide, the positioning part 10 is driven to rotate through the extended telescopic component 7, so that the plane direction of the heat conducting plate 8 is rotated to a vertical position perpendicular to the plane direction of the temperature balancing plate 2, and the power of the fan 3 is triggered to be increased. At this time, on the one hand, the vertically oriented heat conducting plate 8 is bound to bring greater wind resistance, especially when locally overheated, the heat conducting plates 8 in the local area are all rotated to a vertical position, so that the airflow in the local area of ​​the temperature balancing plate 2 rises in a serpentine shape along the heat conducting plate 8, such as Fig. 9As shown, the flow path of the airflow in the temperature equalizing plate 2 is increased (if the overall airflow velocity in the temperature equalizing plate 2 slows down when the power of the fan 3 remains unchanged), and on the other hand, the front and rear sides of the vertical heat conducting plate 8 are respectively pressed against the front and rear sides of the temperature equalizing plate 2, so that the airflow in the local area of ​​the temperature equalizing plate 2 further flows through the heat conducting plate 8 and exchanges heat with the temperature equalizing plate 2, which is equivalent to improving the heat dissipation efficiency in the local area of ​​the temperature equalizing plate 2 (because the heat dissipation path becomes longer and the heat conducting plate 8 contacts the temperature equalizing plate 2 for heat conduction), and reducing the heat dissipation efficiency in the remaining area of ​​the temperature equalizing plate 2. However, since the power of the fan 3 is triggered to be increased at this time (that is, the overall airflow velocity in the temperature equalizing plate 2 is increased), it is equivalent to compensating for the reduced heat dissipation efficiency in the remaining area of ​​the temperature equalizing plate 2, and further improving the heat dissipation efficiency in the local area of ​​the temperature equalizing plate 2. Compared with simply increasing the power of the fan 3 as a whole, adaptive temperature control of the local abnormal area is achieved, which is more energy-saving, and takes into account the advantages of overall active regulation and local independent active regulation of each part or component, so as to achieve the effect of further intelligent energy-saving and temperature control.

[0022] In an embodiment of the present invention, optionally, Figure 1 , Figure 2 , Fig. 9 As shown, when each heat conducting plate 8 rotates to a vertical position, on the one hand, it is used to guide the airflow in the temperature balancing plate 2 to rise in a serpentine shape; on the other hand, the front and rear sides of the heat conducting plate 8 in the vertical position are respectively pressed against the front and rear sides of the temperature balancing plate 2 to increase the heat conduction efficiency.

[0023] More preferably, the front and rear sides of the vertical heat conducting plate 8 can be designed with arc-shaped end faces, and can be designed similar to the existing conventional elastic telescopic tube. A corresponding arc-shaped groove is opened in the temperature balancing plate 2. Then, when the heat conducting plate 8 rotates, the front and rear sides of the heat conducting plate 8 elastically abut against the front and rear sides of the temperature balancing plate 2 until the heat conducting plate 8 rotates to a vertical position. The front and rear sides of the vertical heat conducting plate 8 are attached to the arc-shaped groove, which is conducive to further efficient heat conduction.

[0024] In an embodiment of the present invention, optionally, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the positioning portion 10 includes a positioning rod group arranged outside the rotating shaft 9, the positioning rod group includes two radial rods 101 radially connected to the outer periphery of the rotating shaft 9, and four positioning rod groups are arranged at intervals around the rotating shaft 9. When the telescopic member 7 is in the extended state, as shown in FIG. Figure 1 , Figure 2 , Figure 3As shown, the extended end of the telescopic member 7 is arranged to penetrate the middle gap between the two radial rods 101. More preferably, the extended end of the telescopic member 7 is designed with an arc-shaped end surface. Even if there is a slight deviation in the position between the positioning rod group and the telescopic member 7, it is enough for the extended end of the telescopic member 7 to penetrate the middle gap between the two radial rods 101. As the detection slider 5 continues to slide, the telescopic member 7 has a tendency to elastically return to the initial contracted state, and the extended end of the telescopic member 7 abuts against the radial rod 101. Figure 4 As shown, the radial rod 101 is driven to turn, that is, the positioning rod group, the rotating shaft 9, and the heat conducting plate 8 are driven to rotate until the extended end of the telescopic member 7 is completely separated from the radial rod 101, and the telescopic member 7 is reset to the initial contracted state. More preferably, the telescopic member 7 can also be set to reset to the initial contracted state after a short delay time when the detection slider 5 starts to continue sliding, which is conducive to further stably pushing the heat conducting plate 8 to rotate.

[0025] Among them, if the temperature measuring component 6 initially detects abnormal information that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold during the intermittent monitoring time of the monitoring position, but the abnormal information disappears before the detection slider 5 continues to slide, it means that it may be a previous misdetection. The telescopic component 7 will reset to the initial contracted state, so as not to drive the positioning part 10 to rotate and trigger the power increase of the fan 3, but will send an abnormal monitoring report to the microcontroller for verification and confirmation by the staff. If abnormal monitoring reports are received for the same monitoring position multiple times, it means that the monitoring position may need maintenance and inspection.

[0026] In an embodiment of the present invention, optionally, Figure 1 , Figure 2 As shown, a limiting plate 11 is fixedly connected to one end of the rotating shaft 9 passing through the temperature averaging plate 2. The limiting plate 11 is attached to the side end surface of the outer side of the temperature averaging plate 2 to provide a limiting groove 110, and a corresponding elastically connected limiting block 21 is provided on the outer side wall of the temperature averaging plate 2. More preferably, a plurality of limiting grooves 110 are arranged at intervals along the outer periphery of one side of the limiting plate 11, and the limiting block 21 is designed to be an arc-shaped end surface matching the limiting groove 110. During the rotation of the heat conducting plate 8, the limiting plate 11 pushes the limiting block 21 so that the limiting block 21 elastically retracts into the temperature averaging plate 2 until the heat conducting plate 8 rotates to the initial position or the vertical position, and the limiting block 21 penetrates into the limiting groove 110 for limiting, thereby facilitating the extended end of the telescopic member 7 to push and drive the heat conducting plate 8 to rotate 45° for limiting. On the other hand, the limiting plate 11 also facilitates better sealing at the rotating shaft 9.

[0027] In an embodiment of the present invention, optionally, Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, a filter cartridge 12 is rotatably connected to the bottom opening of the temperature balancing plate 2. The filter cartridge 12 can be designed as a hollow structure, and the outer peripheral surface of the filter cartridge 12 is designed with an opening, which is conducive to ventilation while filtering and blocking dust in the air. The end of the filter cartridge 12 is connected to a barrel shaft 13, and the barrel shaft 13 is rotatably connected to the inner side of the temperature balancing plate 2. One end of the barrel shaft 13 passes through the temperature balancing plate 2 and is connected to a connecting rod 14. Figure 5 As shown, four connecting rods 14 are arranged at intervals along the circumference of the cylinder shaft 13. Specifically, the connecting rod 14 is unidirectionally connected to the cylinder shaft 13. For example, when the detection slider 5 slides down to the bottom end of the guide rail 4, Figure 5 , Figure 6 As shown, the connecting rod 14 is pushed downward by the telescopic member 7 to drive the filter cartridge 12 to rotate axially, and when the detection slider 5 continues to slide upward along the guide rail 4, as shown in FIG. Figure 7 As shown, the telescopic member 7 pushes the connecting rod 14 upward and drives the connecting rod 14 to rotate unidirectionally. Therefore, within a certain sliding period of the detection slider 5, the filter cartridge 12 is regularly driven to rotate axially, so that different surfaces of the filter cartridge 12 face the incoming air for filtering, thereby achieving a better filtering effect.

[0028] The one-way rotation of the connecting rod 14 can be achieved by providing a limiting flange on one side of the rotation connection of the connecting rod 14, or by providing a one-way hinge at the rotation connection, etc., using conventional mechanical methods.

[0029] Among them, the cylindrical shaft 13 can also have the same limit plate 11 and the corresponding limit block 21 designed to achieve a better effect of limiting rotation, and the end of the cylindrical shaft 13 passing through the temperature equalizing plate 2 is longer than the end of the rotating shaft 9 passing through the temperature equalizing plate 2, so that regardless of whether the telescopic part 7 is extended or not, the cylindrical shaft 13 can be driven to rotate.

[0030] In an embodiment of the present invention, optionally, Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a dust collecting chamber 15 is convexly provided on the outer side of the bottom end of the temperature uniform plate 2, and a scraper 16 is connected to the dust collecting chamber 15. One end of the scraper 16 elastically abuts against the outer side of the filter cartridge 12, and a dust collecting box 17 is movably provided at the bottom end of the dust collecting chamber 15. For example, the dust collecting box 17 is a drawer-type structure that can be movably pulled out laterally, which is convenient for cleaning accumulated dust. When the filter cartridge 12 rotates axially, the scraper 16 scrapes off the dust on the outer side of the filter cartridge 12, and the scraped dust falls into the dust collecting box 17 for collection.

[0031] In an embodiment of the present invention, optionally, Figure 1 , Figure 2As shown, because the temperature value detected by the temperature measuring component 6 at each monitoring position will be recorded in the historical data list, when the detection slider 5 slides to the monitoring position where the monitored temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold again, if the temperature detected by the temperature measuring component 6 is less than the calibration value, the telescopic component 7 is triggered to be extended, driving the positioning part 10 to rotate, so that the plane direction of the heat conducting plate 8 at this location is rotated to the initial orientation, and at the same time, the power reduction of the fan 3 is triggered. The calibration value here represents the normal temperature value, that is, no matter whether the temperature detected by the temperature measuring component 6 here is less than the temperature threshold or the temperature change rate is less than the speed change threshold, only when the temperature returns to the calibration value, the return reset of the heat conducting plate 8 and the fan 3 power is triggered.

[0032] In an embodiment of the present invention, optionally, Fig.10 As shown, the heat conducting plates 8 are arranged in groups of two, and the two heat conducting plates 8 in the group are transmission connected, wherein the distance between the heat conducting plates 8 in the group is relatively close, and the distance between the heat conducting plates 8 in different groups is relatively far. The two heat conducting plates 8 in the group may be provided with existing conventional transmission structures such as gear structures, sprocket mechanisms, etc. at their rotating shafts 9, so that the heat conducting plates 8 in the group rotate synchronously. When the detection slider 5 intermittently slides to the first heat conducting plate 8 in the group, if the temperature measuring component 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic component 7 is triggered to be partially extended. At this time, the telescopic component 7 is not enough to extend into the gap of the radial rod 101, until the detection slider 5 intermittently slides to the second heat conducting plate 8 in the group. Since the distance between the heat conducting plates 8 in the group is relatively large, Therefore, the telescopic member 7 is not reset during the sliding process, that is, it maintains a partially extended state. If the temperature measuring member 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic member 7 is triggered to continue to extend to the fully extended state, driving the positioning part 10 to rotate, driving the two heat conducting plates 8 in the group to rotate synchronously, and triggering the power increase of the fan 3. If no abnormal information is detected at any of the heat conducting plates 8 in the group, the telescopic member 7 will obviously not be fully extended. When the detection slider 5 continues to slide to the next group of heat conducting plates 8, the telescopic member 7 is reset to the initial contracted state. In particular, when abnormal information is detected at only one of the heat conducting plates 8 in the group, an abnormal monitoring report will also be sent out. This further avoids misdetection, which is beneficial to intelligent temperature control and energy saving.

[0033] Optionally, the transmission mechanism between the two heat conduction plates 8 can be arranged on the outside of the temperature equalizing plate 2, and the upper and lower positions can be adjusted accordingly, so as to adjust the position of the monitoring position slightly, and realize flexible and slight adjustment of the monitoring position. In actual use, according to the position of the components in the cabinet and the specific power consumption, the redundant monitoring positions can be flexibly adapted to reduce, which is further beneficial to intelligent temperature control and energy saving.

[0034] The present invention also provides a temperature control method for an energy-saving ring network cabinet with intelligent temperature control, comprising the following steps: A temperature averaging plate 2 is attached to the inner wall of the ring network cabinet 1, the temperature averaging plate 2 is designed as a hollow structure, the bottom opening of the temperature averaging plate 2 is designed as an air inlet, and a plurality of fans 3 are arranged horizontally at the top opening of the temperature averaging plate 2 to form an air outlet channel from bottom to top in the temperature averaging plate 2. A plurality of horizontally arranged heat conducting plates 8 are arranged from top to bottom in the temperature averaging plate 2, and the plane direction of each heat conducting plate 8 is in an initial orientation parallel to the plane direction of the temperature averaging plate 2; The detection slider 5 intermittently slides up and down along the guide rail 4. During the intermittent time when the detection slider 5 moves to the monitoring position, the temperature measuring component 6 is triggered to measure the temperature. If the temperature measuring component 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic component 7 is triggered to extend and continue to slide with the detection slider 5. The extended telescopic component 7 drives the positioning part 10 to rotate, so that the planar direction of the heat conduction plate 8 rotates to a vertical position perpendicular to the planar direction of the temperature equalizing plate 2, and at the same time triggers the power of the fan 3 to be increased, so as to realize adaptive temperature control of the local temperature abnormality area.

[0035] More preferably, the bottom opening of the temperature equalizing plate 2 is rotatably connected with a filter cartridge 12, and the detection slider 5 drives the filter cartridge 12 to rotate axially within a certain sliding period, so that different surfaces of the filter cartridge 12 face the incoming air for filtering.

[0036] More preferably, the heat conducting plates 8 are arranged in groups of two. When the detection slider 5 intermittently slides to the first heat conducting plate 8 in the group, if the temperature measuring component 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic component 7 is triggered to be partially extended until the detection slider 5 intermittently slides to the second heat conducting plate 8 in the group. If the temperature measuring component 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, the telescopic component 7 is triggered to continue to extend to a fully extended state, driving the positioning part 10 to rotate, driving the two heat conducting plates 8 in the group to rotate synchronously, and triggering the power increase of the fan 3. If only one heat conducting plate 8 in the group detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the speed change threshold, an abnormal monitoring report is sent.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
