Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, and in particular to an infrared heat management electrical cabinet and a heat management method for a gypsum board production line. Background Art

[0002] Gypsum board production lines are usually composed of a variety of processing equipment and conveying equipment to form an equipment cluster. The power supply and control of these equipment require corresponding electrical cabinets. The electrical cabinets need to control the equipment to complete frequent switching actions (intermittent transportation, climbing and descending, etc.), resulting in some switch-type electrical components being subjected to large instantaneous power. With long-term use, the terminals of the electrical components are aged. At this time, it is easy for the temperature of the electrical component terminals to overheat due to instantaneous high power. If not maintained in time, it may affect the safety of the electrical cabinet operation.

[0003] Therefore, a temperature monitor is usually installed in a conventional electrical cabinet to monitor the temperature inside the electrical cabinet to avoid abnormal heating of electrical components and potential safety hazards. However, such an electrical cabinet equipped with a temperature monitor is usually monitored as a whole, that is, the air temperature in the electrical cabinet is monitored to determine whether the electrical components are abnormally heated. Although this method can monitor the abnormal heating of electrical components in some simple cases (multiple electrical components overheat and have a great impact on the air temperature in the cabinet), it is difficult to independently monitor the wiring terminals of the electrical components. Therefore, when an electrical component terminal is abnormally heated, it has little effect on the air temperature in the cabinet, and it is difficult to detect the overheating problem in time, which leads to the inability to deal with it in time and there are certain safety hazards. Summary of the invention

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] like Figure 1 As shown, the present invention provides an infrared heat management electrical cabinet for a gypsum board production line, comprising:

[0046] A cabinet 1, which includes electrical components installed in sequence;

[0047] The infrared detection structure 2 is arranged on the cabinet door of the cabinet body 1 to face the electrical components. The infrared detection structure 2 includes a plurality of infrared detectors 21, which are arranged in sequence. Each infrared detector 21 receives infrared radiation from the electrical components in a region. After the detection regions of the plurality of infrared detectors 21 are synthesized, the detection field of the infrared detection structure 2 covers all the electrical components.

[0048] The communication bracket 3 is installed on the cabinet door of the cabinet body 1. The communication bracket 3 includes a plurality of branch communication racks 31 arranged one by one corresponding to the electrical component rails. A main communication rack 32 is commonly installed at one end of the plurality of branch communication racks 31. The infrared detector 21 is detachably installed on the branch communication rack 31, and is powered and fed back detection signals through the branch communication rack 31 and the main communication rack 32.

[0049] The thermal management host 4 is installed outside the cabinet 1 and connected to the main communication frame 32. The thermal management host 4 is used to supply power and receive detection signals, and to generate a thermal image based on the detection signal and mark the power connection points of the electrical components in the thermal image to monitor the terminal temperature of each electrical component in real time.

[0050] The electrical cabinet of this embodiment utilizes a plurality of infrared detectors 21 to form an infrared detection structure 2 on the cabinet door of the cabinet body 1, and the infrared detectors 21 are detachably mounted on the branch communication rack 31 of the communication bracket 3, and the plurality of branch communication racks 31 correspond one-to-one to the mounting rails of the electrical components, so that the infrared detectors 21 can adjust the position and quantity according to the serial installation method of the electrical components, and the temperature data of the plurality of infrared detectors 21 are fed back to the thermal management host 4 to form a thermal imaging map covering all electrical components. Therefore, the terminal area of ​​the electrical components in the thermal imaging map can be marked to form temperature monitoring management for the terminal wiring of the electrical components, and timely warn of electrical components with abnormal temperatures.

[0051] Compared with the existing integrated temperature monitoring electrical cabinet, the thermal management electrical cabinet of this embodiment can use multiple infrared detectors 21 to form an infrared detection architecture 2 to perform temperature detection on electrical components. After the temperature data is fed back, the thermal management host 4 can form a thermal imaging map covering all electrical components, that is, it can select the terminal area of ​​the electrical component according to the thermal imaging map for key real-time monitoring, so as to achieve the purpose of temperature monitoring and management of the terminal areas of all electrical components, so that timely warning can be given when any electrical component terminal is overheated, and thermal management is safer and more reliable.

[0052] Based on the above implementation, a preferred embodiment of a branch communication rack 31 is provided below.

[0053] like Figure 2 , Figure 4As shown, the branch communication rack 31 includes a track rack 311, on which two power supply rails 312 and a plurality of communication rails 313 are arranged, the power supply rails 312 are symmetrically arranged, and are respectively electrically connected to the positive and negative electrodes of the thermal management host 4 for power supply, and a plurality of communication rails 313 are arranged between the two power supply rails 312, and are connected to the signal receiving end of the thermal management host 4 for signal transmission;

[0054] Among them, the infrared detector 21 is detachably slidably installed on the track frame 311, and its power supply terminal and communication terminal are respectively slidably abutted on two power supply rails 312 and multiple communication rails 313 to establish communication between the infrared detector 21 and the thermal management host 4, and can slide and adjust its detection position or adjust its number by plugging in the board according to the number and volume of electrical parts installed.

[0055] Specifically, the two power rails 312 enable the infrared detector 21 to obtain the voltage and current required for normal operation, and the communication rail 313 enables the infrared detector 21 to establish communication with the thermal management host 4, thereby obtaining the temperature data (detection signal) fed back by the infrared detector 21;

[0056] The infrared detector 21 can slide on the track frame 311, and its power supply terminal and communication terminal slide and abut against two power supply rails 312 and multiple communication rails 313 respectively, so that the infrared detector 21 can adjust its detection position according to the distribution position of electrical components and volume obstructions, etc., to facilitate debugging.

[0057] Since the infrared detector 21 is connected to the power rail 312 and the communication rail 313 by sliding contact, the sliding part has a certain wear and tear. In order to ensure that the infrared detector 21 is not replaced when the wear and tear reaches a certain level, the following preferred embodiment is provided.

[0058] like Figure 2 As shown, a plug member 22 is provided at the bottom of the infrared detector 21, and the infrared detector 21 is detachably mounted on the plug member 22. A plurality of brush pins 221 are provided at the bottom of the plug member 22, and the power supply terminals and communication terminals of the infrared detector 21 are inserted into the corresponding plurality of brush pins 221 for contact and conduction;

[0059] A carbon brush 222 is provided at the bottom of each brush pin 221 , and each carbon brush 222 is slidably abutted against two power rails 312 and a plurality of communication rails 313 to connect the infrared detector 21 with the power rails 312 and the communication rails 313 .

[0060] Specifically, the plug 22 is installed on the infrared detector 21 to make sliding contact with the power rail 312 and the communication rail 313, thereby avoiding the wear of the infrared detector 21, and the plug 22 can be directly replaced during maintenance.

[0061] Of course, since the plug component 22 needs to be in sliding contact with the power supply rail 312 and the communication rail 313, a carbon brush 222 is set at the lower end of the brush pin 221 of the plug component 22, so that the carbon brush 222 is in sliding contact with the power supply rail 312 and the communication rail 313, which can effectively reduce wear.

[0062] After the plug 22 is installed on the track frame 311, there is a certain assembly gap, and the thermal management host 4 and the infrared detector 21 cannot be disconnected. Especially when the infrared detector 21 is moved for debugging, the infrared detector 21 that is always connected can conveniently observe the changes in the thermal imaging image during its movement and adjustment. Based on this, the following preferred embodiments are provided.

[0063] like Figure 2 , Figure 3 As shown, the lower end of the brush pin 221 is a flat structure, a slot 223 is provided above the carbon brush 222, the lower end of the brush pin 221 is inserted into the slot 223 for active connection, an elastic conductive member 224 is provided in the slot 223, the elastic conductive member 224 connects the lower end of the brush pin 221 and the slot 223 to push the carbon brush 222 to abut against the power rail 312 or the communication rail 313.

[0064] Specifically, the brush pin 221 is inserted into the slot 223 of the carbon brush 222, and the brush pin 221 and the carbon brush 222 are connected and pushed to stretch by the elastic conductive member 224, so that after the plug member 22 is installed on the track frame 311, the carbon brush 222 can be pushed by the elastic conductive member 224 to press tightly against the power supply rail 312 or the communication rail 313 to ensure the stability of the connection.

[0065] During the debugging process of the infrared detector 21, it is necessary to manually move the plug member 22 to adjust the position. Therefore, in order to more conveniently adjust the position of the infrared detector 21, the following preferred embodiments are provided.

[0066] like Figure 2 As shown, two rubber wheels 23 are symmetrically arranged on the side wall of the plug member 22, and the two rubber wheels 23 roll against the outer side wall of the track frame 311;

[0067] A positioning motor 24 is provided on the plug 22, and both ends of the shaft of the positioning motor 24 extend to the two rubber wheels 23 and are connected with a transmission gear set 241 to control the two rubber wheels 23 to synchronously roll and adjust the detection position of the infrared detector 21 on the branch communication rack 31;

[0068] The positioning motor 24 is in contact with the power supply rail 312 and the communication rail 313 through a plurality of brush pins 221 for power supply and communication control.

[0069] Specifically, by arranging rubber wheels 23 on both sides of the plug component 22, the rubber wheels 23 can roll on the outer wall of the track frame 311. When the positioning motor 24 drives the rubber wheels 23 to rotate through the transmission gear set 241, the plug component 22 can move on the track frame 311. Therefore, the position of the plug component 22 can be controlled by controlling the positioning motor 24, so as to realize the electric adjustment of the detection position of the infrared detector 21, which is more convenient to operate and can be directly controlled and adjusted according to the thermal imaging image, which is more intuitive.

[0070] Of course, in order to prevent the rubber wheel 23 from slipping during the adjustment process, the rubber wheel 23 needs to be pressed tightly against the side wall of the track frame 311 to clamp to obtain greater friction to avoid slipping. At this time, the distance between the two rubber wheels 23 is smaller than the width of the track frame 311 (the rubber wheel 23 is deformed after clamping), which makes it difficult to install the plug component 22 on the track frame 311. Based on this, the following preferred embodiments are provided.

[0071] like Figure 2 As shown, two wing plates 225 are symmetrically and slidably inserted on the side wall of the plug member 22, and two rubber wheels 23 and two transmission gear sets 241 are respectively installed on the two wing plates 225. A spring member 226 is provided between the wing plates 225 and the plug member 22 to pull the wing plates 225 to retract toward the plug member 22, so that the two rubber wheels 23 are tightened and clamped on the outer side wall of the track frame 311;

[0072] A telescopic shaft 242 is provided between the positioning motor 24 and the transmission gear set 241 to connect with each other so as to adapt to the retraction and extension activities of the rubber wheel 23 .

[0073] Specifically, the wing plate 225 is movably mounted on the plug member 22 and is tightened by the spring member 226, so that when installing the plug member 22, it is only necessary to stretch the wing plate 225 outward, and after the installation is completed, the wing plate 225 is tightened by the spring member 226, so that the rubber wheel 23 is tightly pressed against the outer wall of the track frame 311, thereby reducing the probability of slipping and improving the accuracy of adjustment;

[0074] In order to ensure that the positioning motor 24 and the transmission gear set 241 are not separated during the movement of the wing plate 225 , a telescopic shaft 242 is provided between the two to connect them so as to adapt to the movement of the wing plate 225 .

[0075] Since the rubber wheel 23 also has a large resistance in the wheel axis direction when clamping and fixing the plug 22, the plug 22 may not be installed properly, resulting in poor contact between the brush pin 221 and the power rail 312 and the communication rail 313. Based on this, the following preferred embodiments are provided.

[0076] like Figure 4As shown, a magnetic strip 314 is provided at the bottom of the track frame 311, and a magnetic plate 227 is provided at the bottom of the plug 22. After the plug 22 is installed on the track frame 311, the magnetic strip 314 generates an attractive force on the magnetic plate 227, so that the plug 22 is pressed against the track frame 311;

[0077] Two groups of balls 228 are disposed at the bottom of the plug 22 . Each group of balls 228 is arranged in a straight line and abuts against the track frame 311 , so as to roll on the track frame 311 when the plug 22 moves.

[0078] Specifically, by arranging a magnetic strip 314 at the bottom of the track frame 311 and arranging a magnetic plate 227 at the bottom of the plug 22, the magnetic strip 314 can generate suction force on the magnetic plate 227 to attract the plug 22 to move toward the track frame 311, so that when the wing plate 225 is opened to install the plug 22, the plug 22 is quickly adsorbed and attached to the track frame 311, thereby avoiding the occurrence of a gap after the plug 22 is installed, which affects the stability of the connection between the brush pin 221 and the power rail 312 and the communication rail 313;

[0079] Of course, in order to ensure that the plug component 22 is adsorbed and pressed against the track frame 311 and can still slide and adjust smoothly, a ball 228 is set at the bottom of the plug component 22 to roll on the track frame 311, which can effectively reduce the sliding friction, which can reduce friction loss and improve the smoothness of adjustment.

[0080] Based on the above embodiments, a preferred embodiment of a main communication rack 32 is provided below.

[0081] like Figure 1 , Figure 5 As shown, the main communication rack 32 includes a power supply bus 321 and a communication bus 322. The two power supply rails 312 and multiple communication rails 313 in each branch communication rack 31 are respectively connected to the power supply bus 321 and the communication bus 322 to establish independent communication between each infrared detector 21 and the thermal management host 4.

[0082] Specifically, the power supply bus 321 and the communication bus 322 connect the two power supply rails 312 and multiple communication rails 313 in each branch communication rack 31 so that they are connected in parallel. The thermal management host 4 can communicate with the infrared detector 21 through the power supply bus 321 and the communication bus 322 as well as the power supply rail 312 and the communication rail 313.

[0083] Of course, the power supply bus 321 and the communication bus 322 also need to be connected to the external thermal management host 4, so the following preferred embodiments are provided.

[0084] like Figure 1As shown, the thermal management host 4 has a power supply port 41 and a communication port 42, one end of the power supply bus 321 extends to the external connection power supply port 41 of the cabinet 1, and one end of the communication bus 322 extends to the external connection communication port 42 of the cabinet 1;

[0085] After receiving the detection signal through the communication port 42 and the communication bus 322, the heat pipe host 4 obtains an infrared thermal imaging image composed of detection data of multiple infrared detectors 21, and marks the terminal area of ​​the electrical component according to the infrared thermal imaging image to monitor the temperature at the terminal connection point.

[0086] Specifically, the power supply port 41 of the thermal management host 4 can adjust its power supply voltage and power supply current according to the number of infrared detectors 21, so that the infrared detectors 21 work at rated power.

[0087] Based on the above infrared thermal management electrical cabinet, a thermal management method for an electrical cabinet is provided, comprising the following steps:

[0088] Step 100: Fix the branch communication rack of the communication bracket to the cabinet door in accordance with the mounting rail of the electrical components, and install a plurality of infrared detectors on the branch communication rack according to the assembly sequence of the electrical components, so that the infrared detectors detect the electrical components directly to obtain temperature data;

[0089] Step 200: Multiple infrared detectors feed back temperature data to the thermal management host through the communication bracket. The thermal management host processes the temperature data of the multiple infrared detectors to form a thermal image. According to the thermal image, the terminal area of ​​each electrical component is manually marked and set as a monitoring point, thereby obtaining the temperature value of each monitoring point.

[0090] Step 300: Set the temperature alarm threshold of each electrical component and start the thermal management host to perform temperature monitoring;

[0091] Step 400: When the thermal management host detects that the temperature of a certain monitoring point exceeds a preset threshold, the thermal management host sends an early warning signal to the control room and marks the location of the electrical component where the temperature is too high.

[0092] Specifically, in step 100, infrared detectors 21 need to be installed on both sides of the larger electrical component to prevent the infrared radiation generated by the smaller electrical component nearby from being difficult to be received by the infrared detector 21 and causing detection corners;

[0093] In step 200, the temperature data fed back by each infrared detector can generate a thermal image, and the thermal images of multiple infrared detectors are synthesized to form a thermal image covering all electrical components. Prior to this, the boundaries of each thermal image are overlapped and trimmed to avoid repeated detection and the situation where the warning position is difficult to accurately locate.

[0094] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
