Description

Infrared thermal management electrical cabinet for gypsum board production line and thermal management method TECHNICAL FIELD

[0001] The present application relates to the technical field of gypsum board production, in particular to an infrared thermal management electrical cabinet for a gypsum board production line and a thermal management method. BACKGROUND

[0002] A gypsum board production line is usually formed by a combination of various processing equipment and conveying equipment to form an equipment cluster. The power supply and control of these devices require corresponding electrical cabinets to complete. The electrical cabinet needs to control the devices to complete frequent switching actions (intermittent conveying, climbing and descending, etc.), which results in a large instantaneous power on some switch-type electrical components. With long-term use, there is an aging condition at the terminals of the electrical components. At this time, the temperature of the terminal part of the electrical component is prone to overheating due to the 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 provided in a conventional electrical cabinet to monitor the temperature in the electrical cabinet to avoid safety hazards caused by abnormal heating of electrical components. However, such an electrical cabinet with a temperature monitor usually monitors the entire cabinet, that is, it determines whether the electrical components are abnormally heated by monitoring the air temperature in the electrical cabinet. Although this method can monitor the abnormal heating of electrical components in some simple cases (where multiple electrical components overheat and have a greater impact on the air temperature in the cabinet), it is difficult to independently monitor the terminals of the electrical components. Therefore, when a terminal of an electrical component abnormally overheats, it has a smaller impact on the air temperature in the cabinet, making it difficult to detect the overheating problem in time and resulting in certain safety hazards.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present application.

[0043] As shown in Fig. 1, the present application provides an infrared thermal management electrical cabinet for a gypsum board production line, comprising:

[0044] A cabinet body 1, the inside of which comprises sequentially installed electrical components;

[0045] An infrared detection framework 2 is arranged on the cabinet door of the cabinet body 1 to face the electrical components. The infrared detection framework 2 comprises a plurality of infrared detectors 21, which are sequentially installed. 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 combined, the detection field of view of the infrared detection framework 2 covers all the electrical components.

[0046] A communication support 3 is installed on the cabinet door of the cabinet body 1. The communication support 3 comprises a plurality of branch communication supports 31, which are arranged one-to-one corresponding to the installation rails of the electrical components. One end of the plurality of branch communication supports 31 is commonly installed with a main communication support 32. The infrared detectors 21 are detachably installed on the branch communication supports 31 and are powered and fed back detection signals through the branch communication supports 31 and the main communication support 32.

[0047] A thermal management host 4 is installed outside the cabinet body 1 and is connected to the main communication support 32. The thermal management host 4 is used for power supply and receiving detection signals and generates a thermal imaging map based on the detection signals and marks the power connection points of the electrical components in the thermal imaging map to monitor the terminal temperature of each electrical component in real time.

[0048] The electrical cabinet of the embodiment utilizes a plurality of infrared detectors 21 to form an infrared detection framework 2 on the cabinet door of the cabinet body 1. The infrared detectors 21 are detachably installed on the branch communication supports 31 of the communication support 3. The plurality of branch communication supports 31 correspond one-to-one to the installation rails of the electrical components, so that the infrared detectors 21 can adjust the position and quantity according to the sequential installation mode of the electrical components. The temperature data of the plurality of infrared detectors 21 is fed back to the thermal management host 4 to form a thermal imaging map covering all the electrical components. Therefore, the terminal region of the electrical components in the thermal imaging map can be marked to form temperature monitoring and management of the terminal connection of the electrical components and timely warning of abnormal temperature of the electrical components.

[0049] Compared with the existing whole temperature monitoring electrical cabinet, the thermal management electrical cabinet of the embodiment can utilize a plurality of infrared detectors 21 to form an infrared detection framework 2 to face the electrical components for temperature detection. After the temperature data is fed back, the thermal management host 4 can form a thermal imaging map covering all the electrical components. That is, the terminal region of the electrical components can be selected according to the thermal imaging map for real-time monitoring. The purpose of temperature monitoring and management of the terminal region of all the electrical components is achieved. When overheating occurs at the terminal of any electrical component, timely warning can be achieved, and the thermal management is more secure and reliable.

[0050] Based on the above embodiment, a preferred embodiment of the branch communication support 31 is provided as follows.

[0051] As shown in FIG. 2, FIG. 4, the branch communication frame 31 comprises a track frame 311, two power supply tracks 312 and a plurality of communication tracks 313 are arranged on the track frame 311, the power supply tracks 312 are symmetrically arranged and are respectively electrically connected to the positive and negative power supply of the thermal management host 4, and the plurality of communication tracks 313 are arranged between the two power supply tracks 312 and are connected to the signal receiving end of the thermal management host 4 to transmit signals.

[0052] The infrared detector 21 is detachably and slidably mounted on the track frame 311, and the power supply terminals and the communication terminals thereof are respectively slidably abutted on the two power supply tracks 312 and the plurality of communication tracks 313, so as to establish the communication between the infrared detector 21 and the thermal management host 4, and the detection position thereof can be adjusted by sliding or the number thereof can be adjusted by inserting the board according to the number and volume of the electrical components.

[0053] Specifically, the two power supply tracks 312 enable the infrared detector 21 to obtain the voltage and current required for normal operation, and the communication tracks 313 enable the infrared detector 21 to establish the communication with the thermal management host 4, so as to obtain the temperature data (detection signal) fed back by the infrared detector 21.

[0054] The infrared detector 21 can slide on the track frame 311, and the power supply terminals and the communication terminals thereof are respectively slidably abutted on the two power supply tracks 312 and the plurality of communication tracks 313, so that the infrared detector 21 can adjust the detection position thereof according to the distribution position of the electrical components and the volume blockage, and the debugging is facilitated.

[0055] Since the infrared detector 21 is conducted in a sliding contact mode with the power supply tracks 312 and the communication tracks 313, there is a certain use loss of the sliding part. In order to ensure that the infrared detector 21 is not replaced when the loss reaches a certain degree, the following preferred embodiment is provided.

[0056] As shown in FIG. 2, a plug member 22 is arranged at the bottom of the infrared detector 21, the infrared detector 21 is detachably mounted on the plug member 22, a plurality of brush pin columns 221 are arranged at the bottom of the plug member 22, and the power supply terminals and the communication terminals of the infrared detector 21 are inserted into the corresponding plurality of brush pin columns 221 to contact and conduct.

[0057] A carbon brush 222 is arranged at the bottom of each brush pin column 221, and each carbon brush 222 is slidably abutted on the two power supply tracks 312 and the plurality of communication tracks 313, so as to connect the infrared detector 21 with the power supply tracks 312 and the communication tracks 313.

[0058] Specifically, the plug member 22 is mounted on the infrared detector 21 to slide contact with the power supply tracks 312 and the communication tracks 313, so as to avoid the wear of the infrared detector 21, and the use loss of the plug member 22 can be directly replaced during maintenance.

[0059] Of course, since the plug member 22 needs to be in sliding contact with the power supply rail 312 and the communication rail 313, a carbon brush 222 is arranged at the lower end of the brush pin column 221 of the plug member 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 the wear.

[0060] Since there is a certain assembly gap after the plug member 22 is installed on the rail frame 311, the thermal management host 4 cannot be disconnected from the infrared detector 21, and in particular, the infrared detector 21 that is always connected can facilitate the observation of the changes in the thermal imaging image during the movement adjustment process. Based on this, the following preferred embodiments are provided.

[0061] As shown in FIGS. 2 and 3, the lower end of the brush pin column 221 is in a flat structure, and the upper end of the carbon brush 222 is provided with a slot 223, the lower end of the brush pin column 221 is inserted into the slot 223 and movably connected, and a flexible conductive member 224 is arranged in the slot 223, the flexible conductive member 224 connects the lower end of the brush pin column 221 and the slot 223 to push the carbon brush 222 against the power supply rail 312 or the communication rail 313.

[0062] Specifically, the brush pin column 221 is inserted into the slot 223 of the carbon brush 222, and the brush pin column 221 and the carbon brush 222 are connected by the flexible conductive member 224 and are pushed to elongate, so that after the plug member 22 is installed on the rail frame 311, the carbon brush 222 can be pushed by the flexible conductive member 224 to tightly abut against the power supply rail 312 or the communication rail 313, to ensure the stability of the connection.

[0063] During the debugging process of the infrared detector 21, the plug member 22 needs to be manually adjusted for position adjustment, therefore, in order to more conveniently adjust the position of the infrared detector 21, the following preferred embodiments are provided.

[0064] As shown in FIG. 2, 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 rail frame 311;

[0065] A position adjusting motor 24 is arranged on the plug member 22, the shaft of the position adjusting motor 24 extends to the two rubber wheels 23 and is provided with a transmission gear set 241 connected to the two rubber wheels 23, to control the synchronous rolling of the two rubber wheels 23 and adjust the detection position of the infrared detector 21 on the branch communication frame 31;

[0066] The position adjusting motor 24 is in contact with the power supply rail 312 and the communication rail 313 through the plurality of brush pin columns 221 for power supply and communication control.

[0067] Specifically, by arranging the rubber wheels 23 on both sides of the plug-in part 22, the rubber wheels 23 can roll on the outer sidewall of the track frame 311, and when the adjusting motor 24 drives the rubber wheels 23 to rotate through the transmission gear set 241, the plug-in part 22 can move on the track frame 311, so that the position of the plug-in part 22 can be controlled by controlling the adjusting motor 24, the detection position of the infrared detector 21 can be electrically adjusted, the operation is more convenient, and the control adjustment can be directly performed according to the thermal imaging image, which is more intuitive.

[0068] Of course, in order to avoid slipping of the rubber wheels 23 during adjustment, the rubber wheels 23 need to be tightly pressed on the sidewall of the track frame 311 to obtain greater friction force to avoid slipping, and at this time, the distance between the two rubber wheels 23 is less than the width of the track frame 311 (the rubber wheels 23 are deformed after clamping), so that the plug-in part 22 is difficult to install on the track frame 311. Based on this, the following preferred embodiments are provided.

[0069] As shown in FIG. 2, two wing plates 225 are symmetrically and slidingly inserted on the sidewall of the plug-in part 22, two rubber wheels 23 and two transmission gear sets 241 are respectively arranged on the two wing plates 225, and a spring member 226 is arranged between the wing plate 225 and the plug-in part 22 to pull the wing plate 225 to shrink towards the plug-in part 22, so that the two rubber wheels 23 are clamped on the outer sidewall of the track frame 311.

[0070] Among them, the adjusting motor 24 and the transmission gear set 241 are connected through the telescopic shaft 242 to adapt to the expansion and contraction of the rubber wheel 23.

[0071] Specifically, the wing plate 225 is movably arranged on the plug-in part 22 and is pulled tightly by the spring member 226, so that when the plug-in part 22 is installed, the wing plate 225 only needs to be stretched outward, and after installation is completed, the wing plate 225 is pulled tightly by the spring member 226, so that the rubber wheel 23 tightly abuts against the outer sidewall of the track frame 311, thereby reducing the probability of slipping and improving the accuracy of adjustment.

[0072] In order to ensure that the adjusting motor 24 and the transmission gear set 241 do not separate during the movement of the wing plate 225, the telescopic shaft 242 is arranged between the two to adapt to the movement of the wing plate 225.

[0073] Since the rubber wheel 23 has a large resistance in the wheel shaft direction when clamping and fixing the plug-in part 22, the plug-in part 22 may not be installed in place, resulting in poor contact between the brush pin column 221 and the power supply rail 312 and the communication rail 313. Based on this, the following preferred embodiments are provided.

[0074] As shown in FIG. 4, a magnetic strip 314 is arranged at the bottom of the track frame 311, and a magnetic plate 227 is arranged at the bottom of the plug-in part 22. After the plug-in part 22 is installed on the track frame 311, the magnetic strip 314 generates an attractive force on the magnetic plate 227 to make the plug-in part 22 tightly abut against the track frame 311.

[0075] Two groups of rolling balls 228 are arranged at the bottom of the plug-in part 22. Each group of rolling balls 228 is arranged in a straight line and abuts against the track frame 311 to roll on the track frame 311 when the plug-in part 22 moves.

[0076] Specifically, by arranging the magnetic strip 314 at the bottom of the track frame 311 and the magnetic plate 227 at the bottom of the plug-in part 22, the magnetic strip 314 can generate an attractive force on the magnetic plate 227 to attract the plug-in part 22 to move towards the track frame 311. Therefore, when the plug-in part 22 is installed on the opening wing plate 225, the plug-in part 22 can be quickly attracted and abut against the track frame 311, thereby avoiding the gap between the plug-in part 22 and the track frame 311 after installation, which affects the stability of the connection between the brush pin column 221 and the power supply track 312 and the communication track 313.

[0077] Of course, in order to ensure that the plug-in part 22 is tightly pressed against the track frame 311 and can still be smoothly adjusted, the rolling balls 228 are arranged at the bottom of the plug-in part 22 to roll on the track frame 311, which effectively reduces the friction force of sliding, reduces the friction loss, and improves the smoothness of adjustment.

[0078] Based on the above embodiment, the following provides a preferred embodiment of the main communication frame 32.

[0079] As shown in FIG. 1 and FIG. 5, the main communication frame 32 includes a power supply bus 321 and a communication bus 322. The two power supply tracks 312 and the plurality of communication tracks 313 in each branch communication frame 31 are connected to the power supply bus 321 and the communication bus 322, respectively, to establish independent communication between each infrared detector 21 and the thermal management host 4.

[0080] Specifically, the power supply bus 321 and the communication bus 322 are connected to the two power supply tracks 312 and the plurality of communication tracks 313 in each branch communication frame 31, which 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 and the power supply track 312 and the communication track 313.

[0081] Of course, the power supply bus 321 and the communication bus 322 also need to be connected to the external thermal management host 4. Therefore, the following preferred embodiment is provided.

[0082] As shown in FIG. 1, the thermal management host 4 is provided with a power supply port 41 and a communication port 42, one end of the power supply bus 321 extends to the outside of the cabinet 1 to connect the power supply port 41, and one end of the communication bus 322 extends to the outside of the cabinet 1 to connect the communication port 42;

[0083] After the thermal management host 4 receives the detection signal through the communication port 42 and the communication bus 322, an infrared thermal image composed of the detection data of the plurality of infrared detectors 21 is obtained, and the terminal area of the electrical component is marked according to the infrared thermal image, so as to monitor the temperature at the terminal wiring position.

[0084] 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 detector 21 is in rated power operation.

[0085] Based on the above-mentioned infrared thermal management electrical cabinet, an electrical cabinet thermal management method is provided, which comprises the following steps:

[0086] Step 100, fix the branch communication rack of the communication support on the cabinet door, and install a plurality of infrared detectors on the branch communication rack according to the assembly sequence of the electrical component, so that the infrared detector directly detects the temperature data of the electrical component;

[0087] Step 200, the plurality of infrared detectors feed the temperature data to the thermal management host through the communication support, the thermal management host processes the temperature data of the plurality of infrared detectors to form a thermal image, manually marks the terminal area of each electrical component as a monitoring point according to the picture of the thermal image, and obtains the temperature value of each monitoring point;

[0088] Step 300, set the temperature alarm threshold of each electrical component, and start the thermal management host to monitor the temperature;

[0089] Step 400, when the thermal management host monitors that the temperature of a certain monitoring point exceeds the preset threshold, the thermal management host sends a warning signal to the control room and marks the position of the electrical component with high temperature.

[0090] Specifically, in step 100, infrared detectors 21 need to be arranged on both sides of the electrical component with large volume, so as to avoid that the infrared radiation generated by the small electrical component near the infrared detector 21 is difficult to be accepted by the infrared detector 21 and the detection of the four corners is generated;

[0091] In step 200, the temperature data fed back by each infrared detector can generate a thermal image, and a thermal image covering all electrical components is formed by synthesizing the thermal images of the plurality of infrared detectors. Before that, the boundary of each thermal image is overlapped and trimmed, so as to avoid the situation that the warning position is difficult to be accurately positioned due to repeated detection.

[0092] The above examples are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements are also considered to fall within the protection scope of the present application.
