Description

Technical Field

[0001] The present invention belongs to the technical field of bus ducts, and specifically relates to an intelligent temperature control monitoring system for bus ducts based on Internet of Things technology. Background Technique

[0002] Internet of Things technology refers to the technology that interconnects various objects, devices, and systems through the Internet, enabling them to communicate and exchange data with each other; in the Internet of Things, objects (such as sensors, intelligent devices, machines, etc.) can collect, transmit, and receive information through embedded sensors, software, and network connections, thus realizing intelligent and automated applications.

[0003] A bus duct is a device used for power transmission, usually used to transmit power from a transformer or a distribution device to distribution equipment. The bus duct has a high current-carrying capacity and is widely used in large buildings and industrial equipment; an intelligent temperature control monitoring system is a system that can monitor and control temperature in real time. An intelligent temperature control monitoring system usually includes sensors, a data processing unit, and a user interface; it can obtain temperature data in real time and issue an alarm or take automatic measures when the temperature is abnormal; and an intelligent temperature control monitoring system for bus ducts based on Internet of Things technology means that the temperature control monitoring system inside the bus duct can transmit temperature data to the cloud or a mobile device through the network, allowing users to remotely monitor.

[0004] A bus duct refers to a closed metal device composed of copper or aluminum busbars. Since the bus duct is often affected by the external environment, the oxidation and corrosion of the bus duct insulator are caused, resulting in too large a resistance of the bus duct conductor, an increase in temperature, and thus a reduction in the working stability and reliability of the bus duct, posing a potential safety hazard for electricity use. The existing method for monitoring the bus duct only installs temperature sensors at fixed points. The temperature sensors installed at fixed points cannot comprehensively monitor the temperature of the bus duct. At the same time, it can only perform the function of temperature monitoring. When the temperature is too high, it can only let workers arrive at the scene for handling by means of an alarm and cannot perform safety control. Therefore, in view of the above problems, improvements are now needed. Summary of the Invention

[0005] To achieve the above object, the present invention provides the following technical solutions: An intelligent temperature control monitoring system for bus ducts based on Internet of Things technology, including a bus duct body. A temperature measuring optical fiber cable is installed on one side of the bus duct body. Above one end of the bus duct body, there is a protective box installed on the indoor roof. One side of the protective box is an open structure, and a control box is installed on the other side of the protective box. At the top inside the protective box, there is a slide rail extending outside the protective box and located directly above the bus duct body. A sealing door is installed on the open side of the protective box. At the bottom of the slide rail, there is a U-shaped moving plate. At the bottom of the U-shaped moving plate, there is a fixedly installed inverted T-shaped fixing block. On both sides of the inverted T-shaped fixing block, there are lifting frames installed. At the lower parts of the two lifting frames, there are vertical plates installed. Between the two vertical plates, there is a semiconductor radiator installed. At the lower parts of the two lifting frames, there are drive components for opening and closing the sealing door.

[0006] Preferably, the bottom of the slide rail is provided with an inverted convex-shaped moving groove. On both sides of the middle of the inverted convex-shaped moving groove, there are symmetrically arranged inclined plane structures. The U-shaped moving plate is located inside the inverted convex-shaped moving groove, and two adjusting shafts are rotatably installed on the upper part of the U-shaped moving plate. At both ends of the two adjusting shafts located inside the inverted convex-shaped moving groove, there are fixedly installed tapered rollers matching the inclined plane structures. Through the setting of the inclined plane structure of the inverted convex-shaped moving groove and the tapered rollers, it can move on a curved track.

[0007] Preferably, in the middle of the two adjusting shafts located inside the U-shaped moving plate, there are fixedly installed worm gears. At the bottom inside the U-shaped moving plate, there is a double-output shaft motor connected to the controller. Both output ends of the double-output shaft motor are connected to worm gears meshing with the two worm gears. At both ends of the slide rail, there are fixedly installed blocks for sealing both ends of the inverted convex-shaped moving groove, so that the U-shaped moving plate can move effectively.

[0008] Preferably, the two drive components include mounting plates fixedly installed on the two vertical plates. At the bottom of the two mounting plates, there are fixedly installed racks. On both end faces of the protective box, there are two rotating pins rotatably installed. At the ends of the four rotating pins located outside the protective box, there are fixedly installed rotating arms. At the upper parts of the four rotating arms, they are rotatably connected to the end faces of the sealing door. One end of one of the rotating pins on any end face of the protective box extends into the protective box and is fixedly installed with a gear. The two gears are respectively meshed with the two racks, so as to effectively open and close the sealing door.

[0009] Preferably, on the lower parts of both sides inside the protective box, there are horizontally square sliding grooves opened. On the opposite sides of the two vertical plates, there are fixedly installed square sliders slidably installed inside the horizontally square sliding grooves, so that the mounting plates and the racks can stably move horizontally for transmission adjustment.

[0010] Preferably, both of the lifting frames include X-shaped movable frames. A connecting plate is installed between the middles of the two X-shaped movable frames, and both of the X-shaped movable frames are rotatably connected to the connecting plate. Adjusting rods A are rotatably connected between the two ends of the upper parts of the two X-shaped movable frames and the lower parts on both sides of the inverted T-shaped fixing blocks, and adjusting rods B are rotatably connected between the two ends of the lower parts of the two X-shaped movable frames and the two vertical plates respectively.

[0011] Preferably, an installation inner groove is formed at the bottom of the inverted T-shaped fixing block. An electric telescopic rod is installed inside the installation inner groove. The electric telescopic rod is connected to the controller. The telescopic end of the electric telescopic rod is fixedly connected to the middle of the top of the connecting plate, so as to effectively adjust the lifting of the semiconductor radiator.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] (1) The intelligent temperature control monitoring system for busbars based on the Internet of Things technology can comprehensively monitor the temperature of the busbars in real time. At the same time, when the temperature of the busbars exceeds the set value, the temperature control device is moved to the high-temperature position through the Internet of Things device for cooling treatment, thus effectively avoiding the reduction of the working stability and reliability of the busbars due to high temperature of the busbars, and avoiding the potential safety hazards of electricity use brought by high temperature. And it can perform safety control before the workers arrive, thus effectively improving the safety of using the busbars;

[0014] At the same time, the intelligent temperature control monitoring system for busbars based on the Internet of Things technology has a simple structure design, is convenient and easy to use, and the control operation is stable and reliable. Its performance can meet the requirements of the safe use of busbars;

[0015] (2) The temperature of the busbar body is comprehensively monitored through the temperature measurement optical fiber cable. The temperature measurement optical fiber cable transmits the temperature of the busbar body to the controller. The controller transmits the signal to the information processor for analysis and processing and then feeds it back to the controller. When the temperature exceeds the set value, the controller turns on the light alarm and the sound alarm for alarming. At the same time, the controller controls the U-shaped moving plate to drive the semiconductor radiator to move on the slide rail and opens the sealing door through the transmission component, so that the semiconductor radiator moves to the position where the busbar body generates high temperature. Then the controller controls the lifting frame to extend and drive the semiconductor radiator to move down and turns on the semiconductor radiator, so that the semiconductor radiator contacts the high-temperature part of the busbar body, and the semiconductor radiator dissipates heat from the high-temperature part, thus providing enough reaction time for manual maintenance;

[0016] (3) Start the double-output shaft motor through the controller, so that the double-output shaft motor drives two worm gears to rotate. The rotation of the two worm gears drives two worm wheels to drive two adjusting shafts to rotate. The rotation of the two adjusting shafts drives four conical rollers to rotate. The four conical rollers roll on the inclined surface structure to drive the U-shaped moving plate to move, and the movement of the U-shaped moving plate drives the inverted T-shaped fixing block, two vertical plates, the semiconductor radiator and the transmission component to move;

[0017] (4) When the U-shaped moving plate, the inverted T-shaped fixing block, two vertical plates and the semiconductor radiator are moved out of the inside of the protection box, the mounting plate drives the rack to move. The movement of the rack drives two gears to rotate and drives the rotating pin to rotate. The rotation of the rotating pin drives the rotating arm to rotate. The rotation of the rotating arm drives the sealing door to be removed from the opening of the protection box and move to the lower side of one side of the protection box without blocking the movement of the semiconductor radiator. Finally, the rack will be separated from the gear, so that the U-shaped moving plate, the inverted T-shaped fixing block, two vertical plates and the semiconductor radiator can effectively move out of the inside of the protection box; when the U-shaped moving plate, the inverted T-shaped fixing block, two vertical plates and the semiconductor radiator move to the inside of the protection box, the sealing door seals the opening of the protection box through the transmission of the rack to the gear, so as to protect the unused semiconductor radiator from dust.

[0018] (5) When the semiconductor radiator moves to the part of the busbar trunk body where high temperature is generated, start the electric telescopic rod to extend through the controller to push the connecting plate to move downward. The downward movement of the connecting plate causes two X-shaped movable frames, four adjusting rods A and four adjusting rods B to rotate and adjust to drive two vertical plates to move downward. The downward movement of the two vertical plates drives the semiconductor radiator to move downward and makes the semiconductor radiator contact with the part of the busbar trunk body where high temperature is generated.

[0028] Embodiment 1, given by Figures 1 to 5 The present invention includes a busbar trunking body 1. A temperature measurement optical fiber cable 2 is installed on one side of the busbar trunking body 1. Above one end of the busbar trunking body 1, there is a protection box 3 installed on the indoor roof. One side of the protection box 3 is an open structure.

The busbar trunking body 1 is installed on the indoor roof through a hanging bracket 31. The top of the slide rail 5 outside the protection box 3 is installed on the indoor roof through a fixing block 32 and expansion bolts, so as to effectively install the busbar trunking body 1 and the slide rail 5.

The temperature-measuring optical fiber cable 2 transmits the temperature of the busbar trunking body 1 to the controller. The controller transmits the signal to the information processor for analysis and processing and then feeds it back to the controller. When the temperature exceeds the set value, the controller turns on the light alarm and the sound alarm for alarming. At the same time, the controller controls the U-shaped moving plate 7 to drive the semiconductor radiator 10 to move on the sliding rail 5 and opens the sealing door 6 through the transmission component, so that the semiconductor radiator 10 moves to the position where the busbar trunking body 1 generates high temperature. Then the controller controls the lifting frame to extend to drive the semiconductor radiator 10 to move down and turns on the semiconductor radiator 10, so that the semiconductor radiator 10 contacts the high-temperature part of the busbar trunking body 1, and the semiconductor radiator 10 dissipates heat from the high-temperature part, thereby providing enough reaction time for manual maintenance.

[0033] The intelligent temperature control monitoring system for busbar trunking based on the Internet of Things technology can monitor the temperature of the busbar trunking in real time and comprehensively.

And it can carry out safety control before the workers arrive, thus effectively improving the safety of the use of the busbar trunking. At the same time, the intelligent temperature control monitoring system for busbar trunking based on the Internet of Things technology has a simple structure design, is convenient and easy to use, and the control operation is stable and reliable. Its performance can meet the requirements of the safe use of the busbar trunking.

At the bottom inside the U-shaped moving plate 7, a double-output shaft motor 16 connected to the controller is installed. Both output ends of the double-output shaft motor 16 are connected with worms 17 meshing with the two worm wheels 15. At both ends of the slide rail 5, stoppers 18 for sealing both ends of the reverse convex moving groove 11 are fixedly installed, so that the U-shaped moving plate 7 can move effectively;

[0036] By starting the double-output shaft motor 16 through the controller, the double-output shaft motor 16 drives the two worms 17 to rotate.
