Description

Technical Field

[0001] This application belongs to the field of temperature and humidity detection technology, specifically relating to a multi-functional integrated temperature and humidity controller that can be replaced without power interruption. Background Technology

[0002] Temperature and humidity monitoring is crucial in electrical cabinets, especially switchgear. Excessive temperature causes the metal components to expand, increasing contact resistance, accelerating equipment wear and shortening lifespan. Conversely, excessively low temperatures make insulation materials brittle, reducing insulation performance. High humidity easily leads to condensation, which seeps into components, reducing insulation resistance, causing leakage and short circuits, and causing metal parts to rust and corrode. Furthermore, abnormal temperature and humidity can also cause partial discharge and thermal stability issues. This not only affects the performance and lifespan of electrical equipment but is also key to ensuring the safe and stable operation of the power system, meeting industry standards, and achieving intelligent operation and maintenance.

[0003] When installing or replacing temperature and humidity sensors, the electrical cabinet door needs to be opened. Due to safety requirements and the type of electrical cabinet, power sometimes needs to be cut off, affecting the normal operation of the circuit. Furthermore, the existing electrical cabinets have relatively enclosed spaces with slow airflow. For sudden, localized changes in temperature and humidity, the temperature and humidity sensors lack sufficient response speed and accuracy, affecting the monitoring of the equipment's operating status. On the other hand, since the cabinets are mostly made of metal, which has high thermal conductivity, changes in external temperature may affect the internal temperature, similarly impacting the accurate determination of the internal temperature.

The air guide branch pipe is connected to the outer air guide slot and bends and extends to the rear side. Its end is connected to a three-way valve.

[0014] The first driving mechanism drives the inner and outer air guide tubes to rotate, which in turn drives the first and second row of fan blades to rotate, exhausting air towards the side away from the sealing window panel.

[0022] Compared with the prior art, the beneficial effects of this application are as follows:

[0023] (1) When this application is used, a groove is made on the cabinet door of the electrical cabinet, and the main partition is fixed to the groove of the cabinet door. The maintenance port is set by using the hinged sealing window plate. When installing or replacing the temperature and humidity sensor, there is no need to open the cabinet door. The sensor can be replaced by rotating the sealing window plate, which is conducive to ensuring the continuous operation of the line.

[0024] (2) This application utilizes a sealed window plate to achieve relative isolation between the air inside and outside the cabinet. The inner and outer guide tubes are used to actively draw in the air inside and outside the cabinet, and the exhaust duct that can move back and forth is used to achieve separate discharge of the detection airflow inside and outside the cabinet. This ensures that the device can detect the temperature and humidity of the air inside and outside the cabinet separately, while preventing the air inside and outside the cabinet from merging, which helps to improve the response speed and accuracy of temperature and humidity detection.

[0025] (3) The design of the air guide ears and exhaust fan blades on the inner guide tube and outer guide tube of this application allows the air inside and outside the cabinet to be drawn out while the inner guide tube and outer guide tube rotate, thereby pushing the air inside and outside the cabinet to move away from the sealed window plate, accelerating the air circulation inside and outside the cabinet, and further improving the response speed and response accuracy of temperature and humidity detection.

[0026] (4) In this application, the drive mechanism is located outside the electrical cabinet to prevent the heat generated during its operation from affecting the accuracy of temperature and humidity detection inside the cabinet. Attached Figure Description

[0046] Example 1

[0047] like Figures 1 to 11 As shown, this application provides a multi-functional integrated temperature and humidity controller that can be replaced without power failure, including: a main partition 1, an operation channel through the front and rear sides of the main partition 1, a sealing window 2 hinged to the operation channel, and a sensor seat 5, an air guide mechanism and an exhaust mechanism provided on the sealing window 2.

[0049] The air guiding mechanism includes an outer air guide duct 8 and an inner air guide duct 7 respectively disposed on the front and rear sides of the sealing window plate 2, and the outer air guide duct 8 and the inner air guide duct 7 are movably connected to the detection chamber;

[0050] The ventilation mechanism includes a movable ventilation duct 10 embedded in the sealing window plate 2, and the ventilation section of the ventilation duct 10 moves on the front and rear sides of the sealing window plate 2.

[0051] The air guiding mechanism and the air exhaust mechanism are connected to the detection chamber through the first pipes 14 located on the left and right sides of the sensor base 5. The first driving mechanism 9 that drives the air guiding mechanism and the second driving mechanism 11 that drives the air exhaust mechanism to move are located on the front side of the sealing window plate 2.

[0052] Specifically, a controller and a wireless transmission module are provided on the front side of the main partition 1. The controller is electrically connected to the sensor base 5, the air guide mechanism and the exhaust mechanism, and the wireless communication module is used to upload temperature and humidity data.

[0053] In this application, a slot is cut into the cabinet door of the electrical cabinet, and the main partition 1 is fixed to the slot of the cabinet door. The maintenance port is set up by using the hinged sealing window plate 2. When installing or replacing the temperature and humidity sensor body 6, there is no need to open the cabinet door. The sensor can be replaced by rotating the sealing window plate 2, which helps to ensure the continuous operation of the circuit. This application sets all the drive mechanisms outside the electrical cabinet to prevent the heat generated by their operation from affecting the accuracy of temperature and humidity detection inside the cabinet.

[0054] Specifically, the sensor base 5 is fixed to the rear side of the sealing window plate 2 by the bracket 54. The bottom end of its mounting groove 51 is provided with a rubber ring that matches the size of the temperature and humidity sensor body 6. The top of the sensor base 5 is provided with a wiring terminal 52, which is used for power supply to the temperature and humidity sensor body 6 and communication with the controller.

[0055] As a preferred option, when selecting a model, a cylindrical temperature and humidity sensor body 6 is chosen, the inner circle size of the rubber ring is adapted to the outer diameter of the temperature and humidity sensor body 6, the detection part of the temperature and humidity sensor body 6 is inserted downwards, and the rubber ring achieves elastic clamping of the temperature and humidity sensor body 6 and sealing of the mounting groove 51.

[0056] Specifically, an extension shaft 74 is provided on the front side of the inner air guide duct 7, which rotatably passes through the sealing window plate 2. Several first air guide ears 72 are provided on the front circumference of the inner air guide duct 7, and several first exhaust fan blades 71 are provided on the rear circumference of the inner air guide duct 7. A first air guide groove extending into the inner cavity of the inner air guide duct 7 is opened on the side of the first air guide ear 72 relative to the rotation direction of the inner air guide duct 7. These first air guide grooves converge to form a rearward-extending inner air guide groove 73. A three-way valve 12 communicating with the inner air guide groove 73 is provided at the rear end of the inner air guide duct 7. The outlet of the three-way valve 12 is connected to the detection chamber through a first pipe 14. Several first exhaust fan blades 71 are provided on the rear circumference of the outer air guide duct 8. The second air guide ear 82 has several second row fan blades 81 arranged around its front periphery. The second air guide ear 82 has a second air guide slot extending into the inner cavity of the outer air guide 8 on the side opposite to the rotation direction of the outer air guide duct 8. The second air guide slots converge to form an outer air guide slot 83 extending forward. An air guide branch pipe 13 is rotatably arranged at the front end of the outer air guide duct 8. The air guide branch pipe 13 is connected to the outer air guide slot 83 and bends and extends to the rear. Its end is connected to the three-way valve 12. The first drive mechanism 9 drives the inner air guide duct 7 and the outer air guide duct 8 to rotate, thereby driving the first row fan blades 71 and the second row fan blades 81 to rotate, exhausting air towards the side away from the sealing window plate 2.

[0057] The first drive mechanism 9 includes a first motor 91, a first drive gear 92 and a clutch gear 93. The first drive gear 92 is located at the end of the output shaft of the first motor 91 and meshes with the clutch gear 93. The clutch gear 93 is located between the front end of the extension shaft 74 and the outer air guide 8. The clutch gear 93 is movably connected to the extension shaft 74 and the outer air guide 8 respectively through a clutch assembly.

[0058] The controller controls the clutch assembly of the clutch gear 93 to rotate, causing the clutch gear 93 to rotate with the extension shaft 74 or the outer air duct 8, which is connected to the first motor 91. This drives the first drive gear 92 to rotate, which in turn drives the clutch gear 93 to rotate, which in turn drives the inner air duct 7 or the outer air duct 8 to rotate. The first air guide ear 72 and the second air guide ear 82 enable the active intake of air from both the inside and outside of the electrical cabinet. At the same time, the rotation of the first row of fan blades 71 and the second row of fan blades 81 accelerates the airflow from both the inside and outside of the cabinet.

[0059] Specifically, the clutch gear 93 has circular grooves with radii that are adapted to the outer air guide tube 8 and the extension shaft 74 at the center of its front and rear sides, respectively. The outer air guide tube 8 and the extension shaft 74 are respectively inserted into the corresponding circular grooves. Several clutch grooves are evenly arranged around the central axis on the side walls of the two circular grooves. A telescopic mechanism 931 is embedded in the clutch groove. A dynamic friction plate 932 is provided at the end of the telescopic shaft of the telescopic mechanism 931. A static friction plate 933 is provided around the end side wall of the outer air guide tube 8 and the extension shaft 74 inserted into the circular groove. The clutch assembly includes the telescopic mechanism 931, the dynamic friction plate 932, and the static friction plate 933.

[0060] The controller controls the extension shaft of the telescopic mechanism 931 in the corresponding circular groove to extend, causing the corresponding dynamic friction plate 932 to abut against the corresponding static friction plate 933, and using friction to achieve the connection between the clutch gear 93 and the extension shaft 74 or the outer air guide duct 8.

[0061] Specifically, the exhaust duct 10 includes a drive section 102 and an exhaust section 101 connected front and rear. The rear end of the exhaust section 101 is slidably sleeved on the front and rear extending branch pipe of the first pipeline 14. A plurality of front and rear extending exhaust elongated holes 103 are evenly opened around the central axis of the exhaust section 101. The exhaust duct 10 slides through the sealing window plate 2 in the front and rear direction. The front and rear sides of the sealing window plate 2 are provided with fixed sealing rings 105 relative to the outer periphery of the exhaust duct 10. The outer periphery of the exhaust section 101 and the outer periphery of the drive section 102 are respectively provided with movable sealing rings 104. When the exhaust duct 10 moves back and forth, when the exhaust elongated hole 103 is completely located on the rear side of the sealing window plate 2, the fixed sealing ring 105 and the movable sealing ring 104 on the front side of the sealing window plate 2 abut. When the exhaust elongated hole 103 is completely located on the front side of the sealing window plate 2, the fixed sealing ring 105 and the movable sealing ring 104 on the rear side of the sealing window plate 2 abut.

[0062] The second drive mechanism 11 includes a second motor 111 disposed on one side of the drive section 102. A second drive gear 112 is disposed on the output shaft of the second motor 111. A drive rack 113 is disposed at the bottom of the second drive gear 112. The drive rack 113 extends back and forth and meshes with the second drive gear 112.

[0063] The controller controls the second motor 111 to rotate, which drives the second drive gear 112 to rotate. Under the reaction action of the drive rack 113, the exhaust duct 10 moves back and forth.

[0064] When it is necessary to test the air inside the cabinet, the controller controls the clutch gear 93 to connect with the extension shaft 74, controls the three-way valve 12 to connect the inner air guide groove 73 of the inner air guide duct 7 with the first pipeline 14, and then controls the second motor 111 to rotate, causing the exhaust duct 10 to move backward until the exhaust port 103 of the exhaust section 101 is completely located behind the sealing window plate 2. The controller then controls the first motor 91 to rotate, driving the inner air guide duct 7 to rotate and draw air from inside the cabinet, thereby realizing the test of the air inside the cabinet.

[0065] When it is necessary to detect the air outside the cabinet, the controller controls the clutch gear 93 to connect with the outer guide tube 8, controls the three-way valve 12 to connect the outer air guide groove 83 of the outer air guide tube 8 to the first pipeline 14 through the air guide branch pipe 14, and then controls the second motor 111 to rotate, so that the exhaust tube 10 moves forward until the exhaust long hole 103 of the exhaust section 101 is completely located in front of the sealing window plate 2. Then, the controller controls the first motor 91 to rotate, driving the outer air guide tube 8 to rotate and draw out the air inside the cabinet, so as to realize the detection of the air outside the cabinet.

[0066] This application utilizes the sealing window plate 2 to achieve relative isolation between the air inside and outside the cabinet. The inner guide tube 7 and the outer guide tube 8 actively draw in the air inside and outside the cabinet respectively, and the exhaust duct 10, which can move back and forth, enables the separate discharge of the detection airflow inside and outside the cabinet. This ensures that the device can detect the temperature and humidity of the air inside and outside the cabinet separately, while preventing the air from mixing. This helps to improve the response speed and accuracy of temperature and humidity detection. The changes in temperature and humidity outside the cabinet are used to calibrate and compare the changes in temperature and humidity inside the cabinet.

[0067] This application can also be used for active air exchange between the inside and outside of the cabinet. While drawing in external air using the external air duct 8, the air is discharged into the cabinet using the exhaust duct 10.

[0068] Preferably, a detection tube 53 is provided on the rear end face of the sensor base 5, and a detection solenoid valve is provided in the inner cavity of the detection tube 53. The inner cavity of the detection tube 53 is connected to the detection chamber through the detection solenoid valve, and the detection solenoid valve is electrically connected to the controller.

[0069] The detection tube 53 is used to provide another air flow channel for detecting air inside the cabinet. When the equipment inside the cabinet operates frequently or is under heavy load, the inner guide tube 7, outer guide tube 8, and exhaust tube 10 are used to quickly detect the temperature and humidity of the air inside and outside the cabinet. During the stable period when the equipment inside the cabinet is operating at low power or idle, the detection solenoid valve is opened to stop the air extraction and exhaust of the inner guide tube 7, outer guide tube 8, and exhaust tube 10, thereby reducing the energy consumption of temperature and humidity detection.

[0070] like Figure 10 and11 As shown, the front end face of the sealing window plate 2 is detachably fitted with an outer shell 3, and a handle 21 is also provided on its front side. The rear side of the main partition plate 1 is fitted with an inner shell 4. The outer shell 3 and the inner shell 4 are used for dust protection of the internal and external equipment, and the handle 21 is used for opening and closing the sealing window plate 2.

[0071] In addition to the fixed sealing ring 105 and the movable sealing ring 104, the junction of the sealing window plate 2 and the main partition plate 1 operating channel, the connection between the air guide branch pipe 13 and the sealing window plate 2, and other parts that may cause air to mix inside and outside the cabinet are sealed.

[0072] The controller is an industrial computer device, the telescopic mechanism 931 is a miniature electric cylinder, and the wireless transmission module is a 4G or 5G communication module.

[0073] Example 2

[0074] Based on the above embodiment 1, this application also provides a method for detecting the temperature and humidity of an electrical cabinet, the specific steps of which are as follows:

[0075] S1: The controller controls the clutch gear 93 to connect with the extension shaft 74, controls the three-way valve 12 to connect the inner air guide groove 73 of the inner air guide tube 7 with the first pipeline 14, and then controls the second motor 111 to rotate, causing the exhaust tube 10 to move backward until the exhaust long hole 103 of the exhaust section 101 is completely located behind the sealing window plate 2. The controller then controls the first motor 91 to rotate, driving the inner air guide tube 7 to rotate and draw air from the cabinet, and detect the temperature and humidity inside the cabinet.

[0076] S2: The controller controls the clutch gear 93 to connect with the outer guide tube 8, controls the three-way valve 12 to make the outer air guide groove 83 of the outer air guide tube 8 connected to the first pipeline 14 through the air guide branch pipe 14, and then controls the second motor 111 to rotate, so that the exhaust tube 10 moves forward until the exhaust long hole 103 of the exhaust section 101 is completely located in front of the sealing window plate 2. Then, the controller controls the first motor 91 to rotate, driving the outer air guide tube 8 to rotate and draw air from the cabinet, so as to realize the detection of the air outside the cabinet.
