Description

Technical Field

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

[0002] A ring main unit is a special type of switchgear, optimized for ring network power supply. That is, compared with the application scenarios of standard switchgears, it does not require complex protection functions and has high requirements for power supply reliability. The internal temperature control of existing ring main units is a key link to ensure their stable operation, reduce failure rates, and extend service life. When operating at high loads, the temperatures of internal circuit breakers, cable joints and other parts can reach over 80°C, accelerating insulation aging. Local hot spots are prone to cause discharges and short circuits, leading to equipment failures. Existing temperature control methods mainly combine passive heat dissipation designs (such as heat dissipation holes and heat sinks in the cabinet), temperature monitoring (such as temperature sensors arranged at multiple points in the cabinet), and active regulation (such as starting or regulating forced ventilation, Peltier coolers, heat pipe radiators, circulating liquid cooling plates, etc. in the cabinet to dissipate heat near heat-generating components) when abnormal temperatures are detected. In the prior art, such as the intelligent ring main unit cable temperature monitoring device and intelligent ring main unit disclosed in Chinese patent document CN115149407A, and an air-insulated intelligent vacuum ring main unit disclosed in CN207947548U, all adopt similar combined temperature control methods. However, no matter which active temperature control device or method is used, if it is placed separately on each part or component in the cabinet, the independent installation and operation control of multiple devices are relatively troublesome, and the active temperature control position is not flexible enough and it is difficult to cover the entire cabinet for temperature control. If a monolithic active temperature control device is simply set in the cabinet, although it can cover the entire cabinet for temperature control and the overall control is relatively convenient, when only local areas or components in the cabinet have abnormal temperatures, there is a problem of low efficiency in separately controlling the temperature of each part or component in the cabinet Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an intelligent temperature-controlled energy-saving ring main unit and a temperature control method thereof, so as to solve the problem that it is difficult to balance the advantages and disadvantages of monolithic active regulation and local independent active regulation on each part or component during the internal temperature control of existing ring main units, and achieve a further intelligent energy-saving temperature control effect

[0004] Based on the above purpose, the present invention provides an intelligent temperature-controlled energy-saving ring main unit, including a ring main unit body:

[0005] A heat pipe is attached to the inner wall of the ring main unit body. The heat pipe has a hollow structure design, and the top and bottom of the heat pipe are open. A plurality of fans are horizontally arranged at the top opening of the heat pipe

[0006] On the inner wall of the ring network cabinet body, a guide rail is vertically arranged beside the heat dissipation plate. A detection slider is slidably connected to the guide rail, and a temperature measuring component is arranged on the detection slider. The guide rail is successively provided with a plurality of monitoring positions at intervals from top to bottom. One side end of the detection slider facing the heat dissipation plate is connected with a telescopic component, and the telescopic component is in an initial contracted state;

[0007] A plurality of horizontally arranged heat conduction plates are arranged in the heat dissipation plate from top to bottom. The adjacent upper and lower heat conduction plates are respectively close to different positions on the left and right sides inside the heat dissipation plate. The plane directions of the heat conduction plates are in an initial orientation parallel to the plane direction of the heat dissipation plate. The end of the heat conduction plate is connected with a rotating shaft, and the rotating shaft is rotatably connected to the inside of the ring network cabinet body. One end of the rotating shaft penetrates out of the heat dissipation plate and is connected with a positioning part. The positioning part is correspondingly located beside the monitoring position. When the detection slider slides to the intermittent position on one side of the positioning part, if the temperature measuring component monitors that the temperature is greater than the temperature threshold or the temperature change rate is greater than the change rate threshold, the telescopic component is triggered to be in an extended state. As 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 into a vertical orientation perpendicular to the plane direction of the heat dissipation plate, and at the same time, the power of the lifting fan is triggered.

[0008] Preferably, the front and rear sides of the heat conduction plate in the vertical orientation respectively abut against the front and rear sides inside the heat dissipation plate. When each heat conduction plate rotates into the vertical orientation, it is used to guide the air flow inside the heat dissipation plate to rise in a serpentine shape.

[0009] Preferably, the positioning part includes a positioning rod group arranged on the outer side of the rotating shaft. The positioning rod group includes two radial rods radially connected to the outer circumference of the rotating shaft. The positioning rod group is arranged at intervals around the circumference of the rotating shaft. When the telescopic component is in an extended state, the extended end of the telescopic component passes through the middle gap between the two radial rods. As the detection slider continues to slide, the extended telescopic component drives the positioning rod group to rotate.

[0010] Preferably, a limiting plate is fixedly connected to the end of the rotating shaft passing through the heat dissipation plate. A limiting groove is opened on the side end face of the limiting plate attached to the outer side of the heat dissipation plate. A limiting block is elastically connected to the corresponding side wall outside the heat dissipation plate. When the heat conduction plate rotates to the initial orientation or the vertical orientation, the limiting block penetrates into the limiting groove for limiting.

[0011] Preferably, a filter cylinder is rotatably connected to the opening at the bottom end of the heat dissipation plate. The end of the filter cylinder is connected with a cylinder shaft, and the cylinder shaft is rotatably connected to the inside of the heat dissipation plate. One end of the cylinder shaft penetrates out of the heat dissipation plate and is connected with a connecting rod. Four connecting rods are arranged at intervals along the circumference of the cylinder shaft. When the detection slider slides to the bottom end of the guide rail, the connecting rod is pushed by the telescopic component to drive the filter cylinder to rotate axially.

[0012] Preferably, a dust collection cavity is convexly arranged on the outer side of the bottom end of the heat dissipation plate. A scraping plate is connected inside the dust collection cavity. One end of the scraping plate elastically abuts against the outer side of the filter cylinder. A dust collection box is movably arranged at the bottom end inside the dust collection cavity. When the filter cylinder rotates axially, the dust accumulated on the outer side of the filter cylinder is scraped off by the scraping plate, and the scraped dust falls into the dust collection box for collection.

[0013] Preferably, when the detection slider slides to the monitoring position again where the monitored temperature is greater than the temperature threshold or the temperature change rate is greater than the variable speed threshold, if the temperature measured by the temperature measuring component is less than the calibration value, the telescopic component is triggered to be in the extended state, and at the same time, the fan power is triggered to be reduced.

[0014] Preferably, the heat conducting plates are arranged in pairs, and the two heat conducting plates in a group are drivingly connected. 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 variable speed threshold, the telescopic component is triggered to be in a partially extended state 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 variable speed threshold, the telescopic component is triggered to be in the fully extended state and drives the positioning part to rotate.

[0015] The present invention also provides a temperature control method for an intelligent temperature-controlled energy-saving ring main unit, including the following steps:

[0016] By pasting a temperature equalizing plate on the inner wall of the ring main unit body, the temperature equalizing plate is designed with a hollow structure, the bottom opening of the temperature equalizing plate is designed as an air inlet, and a plurality of fans are horizontally arranged at the top opening of the temperature equalizing plate to form an air outlet channel from bottom to top in the temperature equalizing plate. A plurality of horizontally arranged heat conducting plates are arranged from top to bottom in the temperature equalizing plate, and the plane directions of the heat conducting plates are in an initial orientation parallel to the plane direction of the temperature equalizing plate.

[0017] The detection slider makes an intermittent reciprocating sliding movement along the guide rail. During the intermittent time when the detection slider moves to the monitoring position, the temperature measuring component is triggered to measure the temperature. If the temperature measuring component monitors that the temperature is greater than the temperature threshold or the temperature change rate is greater than the variable speed threshold, the telescopic component is triggered to be in the extended state. As the detection slider continues to slide, the positioning part is driven to rotate by the extended telescopic component, so that the plane direction of the heat conducting plate rotates into a vertical orientation perpendicular to the plane direction of the temperature equalizing plate, and at the same time, the fan power is triggered to be increased, realizing temperature control for the local temperature abnormal area adaptively.

[0018] Preferably, the heat conducting plates are arranged in pairs. 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 variable speed threshold, the telescopic component is triggered to be in a partially extended state 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 variable speed threshold, the telescopic component is triggered to continue to extend into the fully extended state, driving the positioning part to rotate, driving the two heat conducting plates in the group to rotate synchronously, and triggering the fan power to be increased. If the temperature is greater than the temperature threshold or the temperature change rate is greater than the variable speed threshold at only one heat conducting plate in the group of heat conducting plates, an abnormal monitoring report is sent out.

[0019] Advantages of the present invention: By attaching a heat pipe on the inner wall of the ring network cabinet body, the heat pipe is designed with a hollow structure. The bottom opening of the heat pipe is designed as an air inlet, and a plurality of fans are horizontally arranged at the top opening of the heat pipe to form an air outlet channel from bottom to top in the heat pipe. A plurality of horizontally arranged heat conduction plates are arranged from top to bottom in the heat pipe, and the plane direction of each heat conduction plate is in an initial orientation parallel to the plane direction of the heat pipe. The detection slider makes an intermittent reciprocating sliding movement up and down along the guide rail. During the intermittent time when the detection slider moves to the monitoring position, the temperature measuring element is triggered to measure the temperature. If the temperature measuring element detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the change rate threshold, the telescopic member is triggered to be in an extended state. As the detection slider continues to slide, the positioning portion is driven to rotate by the extended telescopic member, so that the plane direction of the heat conduction plate rotates to a vertical orientation perpendicular to the plane direction of the heat pipe. At the same time, the fan power is increased, realizing temperature control of the local temperature abnormal area adaptively, which is more energy-saving, taking into account the advantages of overall active regulation and local independent active regulation of each part or component, and achieving the effect of further intelligent energy-saving temperature control.

[0035] Such as Figure 1 、 Figure 2As shown in the figure, an energy-saving ring main unit with intelligent temperature control includes a ring main unit body 1. A heat dissipation plate 2 is attached to the inner wall of the ring main unit body 1. The heat dissipation plate 2 is designed with a hollow structure, and the top and bottom of the heat dissipation plate 2 are designed with open structures. A plurality of fans 3 are horizontally arranged at the top opening of the heat dissipation plate 2. A guide rail 4 is vertically arranged on the inner wall of the ring main unit body 1 beside the heat dissipation plate 2. A detection slider 5 is slidably connected to the guide rail 4. A temperature measuring element 6 is arranged on the detection slider 5. The guide rail 4 is provided with a plurality of monitoring positions at intervals from top to bottom. One side end of the detection slider 5 facing the heat dissipation plate 2 is connected with a telescopic member 7, and the telescopic member 7 is in an initial contracted state. A plurality of horizontally arranged heat conduction plates 8 are arranged in the heat dissipation plate 2 from top to bottom. The adjacent upper and lower heat conduction plates 8 are respectively close to different positions on the left and right sides inside the heat dissipation plate 2. The plane directions of the heat conduction plates 8 are in an initial orientation parallel to the plane direction of the heat dissipation plate 2. The end of the heat conduction plate 8 is connected with a rotating shaft 9, and the rotating shaft 9 is rotatably connected to the inside of the ring main unit body. One end of the rotating shaft 9 passes through the heat dissipation plate 2 and is connected with a positioning portion 10. The positioning portion 10 is correspondingly located beside the monitoring position. When the detection slider 5 slides to the intermittent position on one side of the positioning portion 10, if the temperature measuring element 6 monitors that the temperature is greater than the temperature threshold or the temperature change rate is greater than the change rate threshold, the telescopic member 7 is triggered to be in an extended state. As the detection slider 5 continues to slide, the positioning portion 10 is driven to rotate by the extended telescopic member 7, so that the plane direction of the heat conduction plate 8 rotates into a vertical orientation perpendicular to the plane direction of the heat dissipation plate 2, and at the same time, the power of the fan 3 is triggered to be increased.

[0036] Based on the existing structural principle of the ring main unit, by attaching a heat dissipation plate 2 to the inner wall of the ring main unit body 1. Optionally, the heat dissipation plate 2 can be arranged on the inner wall of the back of the ring main unit body 1 without affecting the front door opening. Each component inside the cabinet is installed closely against the heat dissipation plate 2 from top to bottom. The heat dissipation plate 2 is made of an existing material with a high heat conduction coefficient. In particular, the heat dissipation plate 2 is designed with a hollow structure, and the top and bottom of the heat dissipation plate 2 are designed with open structures. The bottom opening of the heat dissipation plate 2 is designed as an air inlet, and a plurality of fans 3 are horizontally arranged at the top opening of the heat dissipation plate 2 for exhausting air upward. As Figure 1 shown in the figure, a linear air outlet channel from bottom to top is formed inside the heat dissipation plate 2, so as to utilize the natural ventilation inside the heat dissipation plate 2 and the external heat dissipation on the back of the heat dissipation plate 2 to form an overall passive temperature control design for the inside of the ring main unit body 1 and each component inside the cabinet. When active temperature control is required, such as active heat dissipation, the heat of each component inside the ring main unit body 1 and inside the cabinet is conducted to the heat dissipation plate 2. By turning on the fan 3 to exhaust air upward and regulating the power of the fan 3, the hot air inside the heat dissipation plate 2 is accelerated to continuously discharge upward, forming an overall efficient active temperature control design. Moreover, the incoming air dust will not directly enter the ring main unit body 1 during the temperature control design, avoiding the dust impact on the ring main unit.

[0037] Meanwhile, a guide rail 4 is vertically provided on the inner wall of the ring network cabinet body 1 beside the heat dissipation plate 2. A detection slider 5 is slidably connected to the guide rail 4, and a temperature measuring component 6 is arranged on the detection slider 5. A plurality of monitoring positions are arranged on the guide rail 4 at intervals from top to bottom. One side end of the detection slider 5 facing the heat dissipation plate 2 is connected with a telescopic component 7, and the telescopic component 7 is in an initial contracted state. Specifically, the temperature measuring component 6 can adopt existing conventional components such as temperature sensors, and the telescopic component 7 can adopt existing conventional components such as electric elastic telescopic rods. A linear motor structure can be adopted inside the guide rail 4, that is, an existing conventional motor drives a lead screw to rotate, and then drives the detection slider 5 meshed with the lead screw to perform vertical linear sliding movement. The lead screw can select an existing reciprocating lead screw component, and by actively setting the start and stop time of the motor, or arranging existing conventional components such as photoelectric sensors at each monitoring position to detect the position of the detection slider 5 and trigger the intermittent stop of the motor, so as to drive the detection slider 5 to perform intermittent sliding movement up and down reciprocally. During the intermittent time when the detection slider 5 moves to the monitoring position, the temperature measuring component 6 is triggered to start measuring temperature, so that it is not necessary to repeatedly arrange a plurality of temperature sensors for temperature measurement in the cabinet, and comprehensive temperature monitoring with flexible adjustable positions can be realized;

[0038] Particularly, a plurality of horizontally arranged heat conduction plates 8 are arranged in the heat dissipation plate 2 from top to bottom, 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 Figure 9As shown, the flow path of the air current inside the heat pipe 2 is increased (if the power of the fan 3 remains unchanged, the overall air current velocity inside the heat pipe 2 becomes slower). On the other hand, the front and rear sides of the heat conduction plate 8 in the vertical direction are respectively abutted against the front and rear sides inside the heat pipe 2. Then, the air current in this local area inside the heat pipe 2 further flows through the heat conduction plate 8 and exchanges heat with the heat pipe 2. Thus, it is equivalent to improving the heat dissipation efficiency in this local area inside the heat pipe 2 (because the heat dissipation path becomes longer and the heat conduction plate 8 contacts the heat pipe 2 for heat conduction). The heat dissipation efficiency in the remaining area inside the heat pipe 2 is reduced. However, since the power of the fan 3 is triggered to increase at this time (i.e., the overall air current velocity inside the heat pipe 2 is increased), it is equivalent to making up for the reduced heat dissipation efficiency in the remaining area inside the heat pipe 2, and further improving the heat dissipation efficiency in this local area inside the heat pipe 2. Compared with simply increasing the power of the fan 3 as a whole, it realizes adaptive temperature control of local abnormal areas, is more energy-saving, takes into account the advantages of overall active regulation and local independent active regulation on each part or component, and achieves the effect of further intelligent energy-saving temperature control.

[0039] In an embodiment of the present invention, optionally, as Figure 1 , Figure 2 , Figure 9 shown, when each heat conduction plate 8 rotates to the vertical direction, on the one hand, it is used to guide the air current inside the heat pipe 2 to rise in a serpentine shape, and on the other hand, the front and rear sides of the heat conduction plate 8 in the vertical direction are respectively abutted against the front and rear sides inside the heat pipe 2, increasing the heat conduction efficiency.

[0040] More preferably, the front and rear sides of the heat conduction plate 8 in the vertical direction can be designed with arc-shaped end faces, and can be designed similar to the existing conventional elastic telescopic cylinder. Arc-shaped grooves are correspondingly opened inside the heat pipe 2. Then, when the heat conduction plate 8 rotates, the front and rear sides of the heat conduction plate 8 elastically abut against the front and rear sides inside the heat pipe 2 until the heat conduction plate 8 rotates to the vertical direction, and the front and rear sides of the heat conduction plate 8 in the vertical direction are attached to the arc-shaped grooves, which is beneficial to further efficient heat conduction.

[0041] In an embodiment of the present invention, optionally, as Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, the positioning part 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 circumference of the rotating shaft 9. The positioning rod group is circumferentially arranged around the rotating shaft 9 at intervals of four. When the telescopic part 7 is in the extended state, as Figure 1 , Figure 2 , Figure 3As shown, the extended end of the telescopic member 7 passes through the middle gap between the two radial rods 101. Preferably, the extended end of the telescopic member 7 is designed with an arc-shaped end face. Even if there is a slight deviation in the position between the positioning rod group and the telescopic member 7, it is sufficient for the extended end of the telescopic member 7 to penetrate into 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 reset to its initial contracted state, and the extended end of the telescopic member 7 abuts against the radial rod 101, as Figure 4 shown, and drives the radial rod 101 to turn, that is, drives the positioning rod group, the rotating shaft 9, and the heat conducting plate 8 to rotate until the extended end of the telescopic member 7 completely disengages from the radial rod 101, and the telescopic member 7 resets to its initial contracted state. Preferably, the telescopic member 7 can also be reset to its initial contracted state after a short delay time when the detection slider 5 starts to continue sliding, which is beneficial to further stably push the heat conducting plate 8 to rotate.

[0042] Among them, if the temperature measuring member 6 monitors abnormal information that the temperature is greater than the temperature threshold or the temperature change rate is greater than the change rate threshold during the intermittent monitoring time at the monitoring position, but the abnormal information disappears before the detection slider 5 continues to slide, it may indicate a previous mismeasurement. Then the telescopic member 7 resets to its initial contracted state, so that it will not drive the positioning part 10 to rotate and trigger an increase in the power of the lifting fan 3, but will send an abnormal monitoring report to the microcontroller for the staff to verify and confirm. If multiple abnormal monitoring reports of the same monitoring position are received, it indicates that the monitoring position may need maintenance and inspection.

[0043] In the embodiment of the present invention, optionally, as Figure 1 、 Figure 2 shown, a limiting plate 11 is fixedly connected to the end of the rotating shaft 9 passing through the temperature equalizing plate 2. A limiting groove 110 is opened on the side end face of the limiting plate 11 attached to the outside of the temperature equalizing plate 2. A limiting block 21 is elastically connected to the corresponding outer side wall of the temperature equalizing plate 2. Preferably, a plurality of limiting grooves 110 are arranged at intervals along the outer circumference of one side of the limiting plate 11, and the limiting block 21 is designed with an arc-shaped end face matching the limiting groove 110. During the rotation of the heat conducting plate 8, the limiting plate 11 pushes against the limiting block 21, so that the limiting block 21 elastically contracts into the temperature equalizing 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. Thus, it is beneficial for the extended end of the telescopic member 7 to push and drive the heat conducting plate 8 to rotate by 45° for limiting. On the other hand, the limiting plate 11 is also beneficial for better sealing at the rotating shaft 9.

[0044] In the embodiment of the present invention, optionally, as 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 heat pipe 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 openings, which is conducive to ventilation while filtering and blocking dust in the air. The end of the filter cartridge 12 is connected to a cartridge shaft 13, and the cartridge shaft 13 is rotatably connected to the inside of the heat pipe 2. One end of the cartridge shaft 13 passes through the heat pipe 2 and is connected to a connecting rod 14, as Figure 5 shown. Four connecting rods 14 are circumferentially arranged at intervals along the cartridge shaft 13. Specifically, the connecting rods 14 are unidirectionally connected to the cartridge shaft 13. For example, when the detection slider 5 slides down to the bottom end of the guide rail 4, as Figure 5 、 Figure 6 shown, the connecting rod 14 is pushed downward by the telescopic member 7 to drive the axial rotation of the filter cartridge 12. When the detection slider 5 continues to slide upward along the guide rail 4, as Figure 7 shown, the telescopic member 7 pushes the connecting rod 14 upward and drives the connecting rod 14 to rotate unidirectionally. Thus, 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 filtration, achieving a better filtration effect.

[0045] Among them, the unidirectional rotation of the connecting rod 14 can be realized by conventional mechanical methods such as arranging a limiting flange on one side of the rotation connection of the connecting rod 14 or setting a one-way hinge at the rotation connection.

[0046] Among them, the same limiting plate 11 and corresponding limiting block 21 can also be designed in cooperation on the cartridge shaft 13 to achieve a better limiting rotation effect, and the end of the cartridge shaft 13 passing through the heat pipe 2 is longer than the end of the rotating shaft 9 passing through the heat pipe 2, so that the cartridge shaft 13 can be driven to rotate regardless of whether the telescopic member 7 extends or not.

[0047] In the embodiment of the present invention, optionally, as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 shown, a dust collection chamber 15 is convexly provided on the outer side of the bottom end of the heat pipe 2. A scraping plate 16 is connected in the dust collection chamber 15. One end of the scraping plate 16 elastically abuts against the outside of the filter cartridge 12. A dust collection box 17 is movably provided at the bottom end in the dust collection chamber 15. For example, the dust collection box 17 is a drawer-type structure that can be laterally pulled out for easy cleaning of the accumulated dust. When the filter cartridge 12 rotates axially, the accumulated dust on the outside of the filter cartridge 12 is scraped off by the scraping plate 16, and the scraped dust falls into the dust collection box 17 for collection.

[0048] In the embodiment of the present invention, optionally, as 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.

[0049] In an embodiment of the present invention, optionally, Figure 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.

[0050] 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.

[0051] The present invention also provides a temperature control method for an energy-saving ring network cabinet with intelligent temperature control, comprising the following steps:

[0052] By attaching a heat pipe 2 to the inner wall of the ring network cabinet 1, the heat pipe 2 is designed with a hollow structure. The bottom opening of the heat pipe 2 is designed as an air inlet, and a plurality of fans 3 are horizontally arranged at the top opening of the heat pipe 2 to form an air outlet channel from bottom to top in the heat pipe 2. A plurality of horizontally arranged heat conducting plates 8 are arranged in the heat pipe 2 from top to bottom, and the plane direction of each heat conducting plate 8 forms an initial orientation parallel to the plane direction of the heat pipe 2.

[0053] The detection slider 5 slides intermittently 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 element 6 is triggered to measure the temperature. If the temperature measuring element 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the change rate threshold, the telescopic member 7 is triggered to be in the extended state. As the detection slider 5 continues to slide, the positioning portion 10 is driven to rotate by the extended telescopic member 7, so that the plane direction of the heat conducting plate 8 rotates to a vertical orientation perpendicular to the plane direction of the heat pipe 2, and at the same time, the power of the fan 3 is increased to adaptively control the temperature of the local temperature abnormal area.

[0054] More preferably, a filter cylinder 12 is rotatably connected to the bottom opening of the heat pipe 2. During a certain sliding period of the detection slider 5, the filter cylinder 12 is driven to rotate axially, so that different surfaces of the filter cylinder 12 face the air inlet for filtration.

[0055] More preferably, the heat conducting plates 8 are arranged in pairs. When the detection slider 5 intermittently slides to the first heat conducting plate 8 in the pair, if the temperature measuring element 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the change rate threshold, the telescopic member 7 is triggered to be in a partially extended state until the detection slider 5 intermittently slides to the second heat conducting plate 8 in the pair. If the temperature measuring element 6 detects that the temperature is greater than the temperature threshold or the temperature change rate is greater than the change rate threshold, the telescopic member 7 is triggered to continue to extend to a fully extended state, driving the positioning portion 10 to rotate, driving the two heat conducting plates 8 in the pair to rotate synchronously, and triggering the power of the fan 3 to be increased. If the temperature is greater than the temperature threshold or the temperature change rate is greater than the change rate threshold only at one of the heat conducting plates 8 in the pair of heat conducting plates 8, an abnormal monitoring report is sent out.

[0056] Those of ordinary skill in the art should understand that the discussion of any embodiment above is only exemplary and is not intended to imply that the scope of the present invention is limited to these examples; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above, which are not provided in detail for the sake of brevity.
