Description

Technical Field

[0001] This invention relates to the field of transformer protection technology, and more specifically, to a remote anti-theft special transformer based on the Internet of Things. Background Technology

[0002] A special transformer is a device that converts a fixed voltage into another voltage level for transmission. Transformers are one of the most important pieces of equipment in the power supply link of power grid construction. As the main equipment for the operation of the power system, the safe and stable operation of transformers is of paramount importance, which largely depends on the operating conditions of the transformers. With the rapid development of society, people are also facing more safety issues, especially the safety of transformers in power equipment.

[0003] Considering that transformers are generally installed outdoors, in outdoor settings such as residential areas, parks, and remote suburbs, transformers are easily targeted by thieves due to their exposure and lack of real-time monitoring. At the same time, they also need to withstand the harsh environmental effects of sun, rain, wind and sand erosion for a long time. Traditional protection methods such as installing fences and regular inspections are not only inefficient and costly, but also difficult to achieve real-time protection and remote control. In view of this, we propose a remote anti-theft special transformer based on the Internet of Things. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a remote anti-theft special transformer based on the Internet of Things;

[0005] To achieve the above objectives, the present invention provides a remote anti-theft special transformer based on the Internet of Things, including a base body, a transformer body fixedly connected to the inner cavity of the base body, four support columns fixedly connected to the top of the base body, and a rain shield fixedly connected to the top of the support columns.

[0006] Each of the support columns is equipped with a liftable protective component. When the protective component is lowered, it forms a four-way protective enclosure around the base body. The top of the base body is also equipped with an anti-theft component, which includes a pressure sensing device fixedly connected to the top of the base body and a connecting column set on the surface of the protective component.

[0007] When the protective component is fully lowered, the surface of the connecting column gradually comes into contact with the pressure sensing device, forming an anti-theft monitoring loop. When the protective component is subjected to abnormal external force, the pressure sensing device detects the pressure change and triggers an alarm signal. The outer surfaces of the four supporting columns are jointly fixedly connected to an annular fixing frame. The fixing frame adopts a square frame structure. There are four protective components, which are respectively installed on the four sides of the fixing frame.

[0008] The ring-shaped frame fixing bracket outside the four support columns, together with four liftable protective components, can form a four-way protective enclosure around the base when the protective components are lowered, preventing external environmental factors from damaging the transformer. The pressure sensing device in the anti-theft component and the connecting column set on the surface of the protective component form an anti-theft monitoring loop when the protective component is fully lowered. If there is any prying or impact by a thief, the pressure sensing device can quickly detect the pressure change and trigger an alarm signal, promptly alerting relevant personnel, effectively preventing the transformer from being stolen or maliciously damaged, and ensuring the safety of power facilities.

[0009] As a further improvement to this technical solution, the protective component includes a rotating rod that rotates on the surface of the fixed frame. One end of the roller blind is fixedly connected to the outer circumferential surface of the rotating rod and is wound around the circumferential direction of the rotating rod. A threaded rod is rotatably connected to the inner cavity of the support column. A drive motor is fixedly connected to the end of the threaded rod. The drive motor is located in the inner cavity of the base body. A threaded sleeve is threadedly connected to the surface of the threaded rod. Two connecting rods are fixedly connected to the surface of the threaded sleeve. The outer end of each connecting rod is fixedly connected to the surface of the adjacent roller blind. Two limiting grooves are opened on the surface of the support column. The surface of the connecting rod slides on the inner wall of the limiting groove. A fixed column is fixedly connected to the inner wall of the support column. A threaded rod is rotatably connected to the inner wall of the fixed column. A worm is fixedly connected to the end of the threaded rod. Two worm wheels are meshed on the outer side of the worm. The two worm wheels are asymmetrically distributed on the same side of the worm, and their rotation axes are perpendicular to the axis of the worm. The axis of each worm wheel is fixedly connected to the corresponding rotating rod. The rotating rod is used to wind the roller blind.

[0010] When the threaded rod rotates clockwise, the threaded sleeve moves downward along the threaded rod, and the connecting rod simultaneously drives the roller blind to unfold downward. The downward pull of the roller blind drives the rotating rod to rotate synchronously. If one threaded rod drives two adjacent roller blinds to move, then there are two threaded rods to drive the other two roller blinds to move. When the threaded rod rotates counterclockwise, the threaded sleeve moves upward along the axis of the threaded rod, pulling the adjacent roller blinds upward through the connecting rod. At the same time, the threaded rod drives the worm to rotate counterclockwise synchronously. The worm drives two worm wheels on the same side to rotate in the same direction through tooth surface meshing. The rotation of the worm wheels drives the rotating rod to rotate in the same direction, so that the roller blinds are synchronously rolled up to the surface of the rotating rod. Since the two worm wheels are located on the same side of the worm and are asymmetrically distributed, the single helix direction of the worm, such as right-hand helix, can ensure that the two worm wheels rotate in the same direction, avoiding the problem of opposite rotation caused by the unidirectional helix of the worm in the traditional symmetrical layout.

[0011] As a further improvement to this technical solution, a first monitoring device is fixedly connected to the top of the rain shield, a second monitoring device is fixedly connected to the end of the rain shield away from the first monitoring device, the connecting column is fixedly connected to the bottom of the roller shutter, and a connecting groove is opened on the surface of the pressure sensing device, with the inner wall of the connecting groove in contact with the surface of the connecting column.

[0012] The first monitoring system is responsible for monitoring the external space of the base body, and can promptly capture abnormal activities of surrounding personnel and vehicles, such as suspicious persons approaching or staying abnormally, and provide early warning of potential theft or vandalism. The second monitoring system is used to monitor the internal cavity space of the base body, and can view the operating status of the transformer body in real time, and promptly detect abnormalities inside the equipment. The connecting column is fixed at the bottom of the roller shutter and is adapted to the connecting groove on the surface of the pressure sensing device to form a stable contact.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] In this IoT-based remote anti-theft special transformer, an anti-theft monitoring loop composed of a pressure sensor and connecting column can monitor the status of the protective components in real time. Once an abnormal external force such as prying or impact is encountered, the pressure sensor quickly detects the pressure change and triggers an alarm signal. Compared with traditional methods such as fencing and regular inspections, this greatly improves the response speed to theft, effectively deterring thieves, reducing the risk of transformer theft, and ensuring the safety of power facilities. The liftable protective components form a four-way protective enclosure around the base when descending, effectively resisting the impact of harsh environments such as sun, rain, wind, and sand erosion on the transformer body. When the transformer needs maintenance or inspection, after receiving a legitimate operation command, the protective components can quickly rise to release the protective state, the connecting column disengages from the pressure sensor, and the anti-theft monitoring loop is disconnected, allowing maintenance personnel to easily access the transformer body without a complicated disassembly process.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example

[0028] Please see Figures 1-7 As shown, this embodiment provides a remote anti-theft special transformer based on the Internet of Things, including a base body 1, a transformer body 10 fixedly connected to the inner cavity of the base body 1, four support columns 11 fixedly connected to the top of the base body 1, and a rain shield 12 fixedly connected to the top of the support columns 11.

[0029] Each support column 11 is equipped with a liftable protective component 2. When the protective component 2 is lowered, it forms a four-way surrounding protection for the base body 1. The top of the base body 1 is also equipped with an anti-theft component 3. The anti-theft component 3 includes a pressure sensing device 31 fixedly connected to the top of the base body 1, and a connecting column 32 set on the surface of the protective component 2.

[0030] When the protective component 2 is fully lowered, the surface of the connecting column 32 gradually comes into contact with the pressure sensing device 31, forming an anti-theft monitoring loop. When the protective component 2 is subjected to abnormal external force, the pressure sensing device 31 detects the pressure change and triggers an alarm signal.

[0031] As the protective component 2 descends along the support column 11, it forms a four-sided enclosed structure to prevent external intrusion. The connecting column 32 descends with the protective component 2 and eventually contacts the pressure sensing device 31, forming an anti-theft monitoring circuit. In the normal closed state, the pressure sensing device 31 maintains a stable pressure value. When the roller shutter 25 is subjected to external impact, such as prying, hitting, or forcibly lifting, the contact pressure between the connecting column 32 and the pressure sensing device 31 changes abnormally. The pressure sensing device 31 detects the pressure fluctuation and triggers an alarm signal. When subsequent maintenance is required and a legitimate operation command is received, the lifting mechanism drives the protective component 2 to rise, releasing the protective state. The connecting column 32 disengages from the pressure sensing device 31, the anti-theft monitoring circuit is disconnected, and the device enters a non-alarm mode.

[0032] The improvement in this embodiment is as follows:

[0033] Considering that transformers are generally installed outdoors, in outdoor settings such as residential areas, parks, and remote suburbs, transformers are easily targeted by thieves due to their exposure and lack of real-time monitoring. They also need to withstand harsh environmental conditions such as sun, rain, and wind erosion. Traditional protection methods, such as installing fences and regular inspections, are not only inefficient and costly, but also difficult to achieve real-time protection and remote control. Therefore, the anti-theft monitoring loop formed by the pressure sensor 31 and the connecting column 32 can monitor the status of the protective component 2 in real time. Once it encounters abnormal external forces such as prying or impact, the pressure sensor 31 quickly detects the pressure change and triggers an alarm signal. Compared with traditional methods… Fences and regular inspections greatly improve the response speed to theft, effectively deterring thieves, reducing the risk of transformer theft, and ensuring the safety of power facilities. The liftable protective component 2 forms a four-way protective enclosure around the base body 1 when it descends, effectively resisting the impact of harsh environments such as sun, rain, wind, and sand erosion on the transformer body 10. When the transformer needs to be repaired or inspected, after receiving a legitimate operation command, the protective component 2 can quickly rise to release the protective state, the connecting column 32 disengages from the pressure sensing device 31, and the anti-theft monitoring circuit is disconnected, allowing maintenance personnel to easily access the transformer body 10 without a complicated disassembly process.

[0034] In order to enable the protective components 2 to cover the four sides of the base body 1, the outer surfaces of the four support columns 11 are jointly fixedly connected to the annular fixing frame 14. The fixing frame 14 adopts a square frame structure, and there are four protective components 2, which are respectively installed on the four sides of the fixing frame 14.

[0035] By installing the four protective components 2 on the surface of the mounting bracket 14, the four protective components 2 will surround the four sides of the base body 1, respectively, to protect the transformer body 10 inside the base body 1.

[0036] In order for the protective component 2 to protect the transformer body 10 inside the base body 1, it is necessary to further disclose the parts of the protective component 2. Therefore, the protective component 2 includes a rotating rod 240 that rotates on the surface of the fixed frame 14. One end of the roller shutter 25 is fixedly connected to the outer circumferential surface of the rotating rod 240 and is wound around the circumference of the rotating rod 240. When the rotating rod 240 is driven by the driving mechanism to rotate clockwise, the rotating rod 240 releases the wound roller shutter 25, so that the roller shutter 25 moves downward in the vertical direction and gradually unfolds (at point S1-S2) under the combined action of its own weight and the rotation driving force of the rotating rod 240.

[0037] To enable the roller blind 25 to descend, the driving mechanism of the roller blind 25 needs to be further disclosed. Therefore, a threaded rod 21 is rotatably connected to the inner cavity of the support column 11, and a drive motor is fixedly connected to the end of the threaded rod 21. The drive motor is located in the inner cavity of the base body 1. A threaded sleeve 210 is threadedly connected to the surface of the threaded rod 21, and two connecting rods are fixedly connected to the surface of the threaded sleeve 210. The outer end of each connecting rod is fixedly connected to the surface of the adjacent roller blind 25. When the threaded rod 21 rotates clockwise, the threaded sleeve 210 moves downward along the threaded rod 21, and the connecting rods synchronously drive the roller blind 25 to unfold downward. The downward pull of the roller blind 25 drives the rotating rod 240 to rotate synchronously. One of the threaded rods 21 drives two adjacent roller blinds 25 to move. Therefore, there are two threaded rods 21 to drive the other two roller blinds 25 to move.

[0038] In order to enable the threaded sleeve 210 to move vertically downward, two limiting grooves 110 are provided on the surface of the support column 11, and the surface of the connecting rod slides on the inner wall of the limiting groove 110. When the threaded rod 21 rotates, the threaded sleeve 210 will be threadedly connected to the threaded rod 21. Since the connecting rod is located on the inner wall of the limiting groove 110, the threaded sleeve 210 can move axially and will not rotate due to the rotation of the threaded rod 21.

[0039] Considering that the transformer body 10 also requires frequent maintenance and inspection after installation, a fixed column 22 is fixedly connected to the inner wall of the support column 11, and a threaded rod 21 is rotatably connected to the inner wall of the fixed column 22. A worm 23 is fixedly connected to the end of the threaded rod 21, and two worm wheels 24 are meshed on the outer side of the worm 23. The two worm wheels 24 are asymmetrically distributed on the same side of the worm 23, and their rotation axes are perpendicular to the axis of the worm 23. The axis of each worm wheel 24 is fixedly connected to the corresponding rotating rod 240. The rotating rod 240 is used to wind the roller shutter 25. When the threaded rod 21 rotates counterclockwise, the threaded sleeve 210 moves upward along the axis of the threaded rod 21, and pulls the adjacent roller shutter 25 upward through the connecting rod 211.

[0040] Simultaneously, the threaded rod 21 drives the worm 23 to rotate counterclockwise in sync. The worm 23 drives the two worm wheels 24 on the same side to rotate in the same direction, either clockwise or both counterclockwise, depending on the direction of the worm's rotation. The rotation of the worm wheels 24 drives the rotating rod 240 to rotate in the same direction, causing the roller shutter 25 to roll up to the surface of the rotating rod 240 in sync. Since the two worm wheels 24 are located on the same side of the worm 23 and are asymmetrically distributed, the single direction of rotation of the worm 23, such as right-hand rotation, can ensure that the two worm wheels 24 rotate in the same direction, for example, both clockwise, avoiding the problem of opposite rotation caused by the unidirectional spiral of the worm 23 in the traditional symmetrical layout.

[0041] A first monitoring device 13 is fixedly connected to the top of the rain shield 12, and a second monitoring device 130 is fixedly connected to the end of the rain shield 12 away from the first monitoring device 13. The space outside the base body 1 can be monitored by the first monitoring device 13, while the second monitoring device 130 is used to monitor the space inside the base body 1.

[0042] In order for the connecting post 32 to move downward with the protective component 2, the position of the connecting post 32 needs to be further disclosed. Therefore, the connecting post 32 is fixedly connected to the bottom of the roller shutter 25. The pressure sensing device 31 has a connecting groove 310 on its surface, and the inner wall of the connecting groove 310 is adapted to contact the connecting post 32. When the roller shutter 25 moves downward, it will synchronously drive the connecting post 32 to move downward, so that the surface of the connecting post 32 gradually contacts the inner wall of the connecting groove 310.

[0043] In practical applications, this invention, based on the Internet of Things, utilizes a remote anti-theft special transformer:

[0044] S1 Protection Deployment: The drive motor drives the threaded rod 21 to rotate clockwise, and the threaded sleeve 210 moves downward along the threaded rod 21. The connecting rod pulls the roller blind 25 downward to unfold. At the same time, the downward pull of the roller blind 25 drives the rotating rod 240 to rotate. The four roller blinds 25 unfold and descend synchronously to form a four-way surrounding protection for the base body 1. The connecting column 32 moves down with the roller blind 25 and finally contacts the connecting groove 310 of the pressure sensing device 31 to form an anti-theft monitoring circuit. The pressure sensing device 31 maintains a stable pressure value.

[0045] S2 Anti-theft Monitoring: When the roller shutter 25 is subjected to abnormal external forces such as prying or impact, the pressure between the connecting column 32 and the pressure sensing device 31 changes. After the pressure sensing device 31 detects the pressure fluctuation, it triggers an alarm signal.

[0046] S3 Protection Retraction: Upon receiving a legitimate maintenance instruction, the drive motor drives the threaded rod 21 to rotate counterclockwise, the threaded sleeve 210 moves upward, and the roller shutter 25 is pulled upward through the connecting rod. At the same time, the threaded rod 21 drives the worm gear 23 to rotate counterclockwise synchronously. The worm gear 23 drives the two worm wheels 24 on the same side to rotate in the same direction, thereby driving the rotating rod 240 to rotate, and retracting the roller shutter 25 to the surface of the rotating rod 240. The connecting column 32 disengages from the pressure sensing device 31, the anti-theft monitoring circuit is disconnected, and the device enters the non-alarm mode, which facilitates the maintenance of the transformer body 10. If one threaded rod 21 drives two adjacent roller shutters 25 to move, then there are two threaded rods 21 to drive the other two roller shutters 25 to move.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
