Description

Technical Field

[0001] This invention belongs to the field of transformer cabinet technology, and specifically relates to a transformer cabinet with anti-theft alarm function for use in business halls. Background Technology

[0002] With the widespread adoption and increasing intelligence of modern power systems, substations play an indispensable role in power transmission and distribution, and are widely used in various locations. However, theft prevention and security issues of substations in public areas such as business halls have gradually become apparent. Especially with the increasing variety of services offered in business halls and the dense arrangement of electrical equipment, the electrical components and control circuits within the substations have also become increasingly valuable. These components are not only expensive but also crucial to the normal operation of the business hall. If they are vandalized or illegally intruded upon, it could lead to equipment damage, business disruptions, or even more serious security incidents. Therefore, theft prevention and protection of substations in business halls is particularly necessary.

[0003] Existing substation cabinets typically prioritize power transmission and control functions, resulting in relatively simple cabinet designs without dedicated anti-theft or alarm features. Conventional substation cabinet door locks rely on simple mechanical structures, requiring manual unlocking. However, these mechanical locks are easily compromised, allowing unauthorized personnel to pry open the locks and enter the cabinet, posing a significant security risk. Furthermore, ordinary mechanical locks are not integrated with alarm systems; even if the lock is damaged or the door is illegally opened, no alarm will be triggered in time, rendering them ineffective. Therefore, existing substation cabinets, especially in public areas like business halls, lack necessary anti-theft alarm measures, making them vulnerable to theft or damage to electrical equipment and disrupting the normal operation of the power system.

[0004] To address the aforementioned issues, some technical solutions have begun to incorporate new lock structures such as electronic locks and combination locks. However, these solutions often focus on optimizing the lock's structure itself, failing to effectively integrate the anti-theft lock with the alarm system, thus failing to achieve real-time, intelligent anti-theft alarm functionality. Even when some solutions initially achieve anti-theft alarm functionality, their alarm methods are relatively simple, lacking multi-layered and multi-level security protection measures. Furthermore, existing alarm devices have limited sensitivity and response speed, making them prone to false alarms due to external environmental interference or operational errors. In addition, traditional anti-theft alarm technologies, while providing alarm functionality, lack a precise locking transmission system, making it difficult to ensure both security and stability while simultaneously ensuring smooth unlocking and locking operations. This fails to meet the dual demands of high-frequency transmission and high security in real-world scenarios. Therefore, designing a substation cabinet that integrates anti-theft, alarm, and precise unlocking functions has become an urgent need for solutions in the electrical equipment of business halls. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a substation with an anti-theft alarm function for business halls. The specific technical solution is as follows:

[0006] This invention provides a substation cabinet with anti-theft alarm function for use in business halls. It includes a vertically erected cabinet body with a hinged and swivel cabinet door. A three-color warning light is mounted on the top of the cabinet body. An anti-theft component is embedded in the middle edge of the cabinet door, comprising a first anti-theft mechanism and a second anti-theft mechanism, connected to the three-color warning light. The first anti-theft mechanism has an unlocking mechanism. The first anti-theft component is characterized by a square lock shell surrounding its outer periphery, with a middle plate inserted inside the lock shell. A motor with contacts is longitudinally fixed at the front end of the middle plate, and a conductive plate is mounted on its side. The rotating part of the motor has primary transmission wheels arranged in an alternating pattern, and secondary transmission wheels are arranged through progressively coupled connections. The system includes a multi-stage transmission wheel and a three-stage transmission wheel for precise transmission. The multi-stage transmission wheel is transversely mounted on the middle plate. A reset block is coaxially sleeved on the three-stage transmission wheel. A torch-shaped reset trigger and a locking device tightly fastened to it are screwed onto the middle plate at the rear end of the three-stage transmission wheel. The locking device has a U-shaped opening for engaging with the locking tongue embedded on the edge of the cabinet. A reset torsion spring is pressed onto the reset trigger, and a locking torsion spring is pressed onto the locking device for resetting and locking the reset trigger and locking device. A lock cylinder is suspended at the contact point. A wing-shaped lock spring is attached to the bottom of the lock cylinder. A guide plate extends from the front end of the bottom of the lock spring, and an elastic lever is attached to its rear end for connecting the motor circuit to unlock when rotating.

[0007] The first anti-theft mechanism has two states: locked and unlocked. In the unlocked state, the motor stops, the multi-stage transmission wheels are locked, the locking device rotates continuously through the locking torsion spring, and maintains the locked position with the help of the reset trigger of the reset torsion spring, locking the latch on the cabinet. In the unlocked state, the unlocking mechanism rotates, and the guide plate and lever on it connect the contacts and the guide plate respectively. The motor starts, the multi-stage transmission wheels rotate sequentially, and the reset block on the third-stage transmission wheel rotates clockwise, pushing the reset trigger to rotate. The locking device unlocks clockwise with the locking torsion spring, releasing the latch.

[0008] As a preferred embodiment of the present invention, the second anti-theft mechanism includes a base plate symmetrically attached to the inner side of the cabinet door and a fixed post embedded in the side of the cabinet. A hollow cylinder with a through-hole is mounted on the base plate, and a cylindrical locking bolt is inserted along the axial direction of the hole. An elastic rope is sleeved at the tail end of the locking bolt along the hole. A disc-shaped limiter is provided around the locking bolt. A spring is sleeved on the locking bolt section between the limiter and the hollow cylinder, which can be squeezed and stretched along the axial direction. The fixed post has a bolt hole adapted to the locking bolt for immediate locking of the second anti-theft mechanism.

[0009] As a preferred embodiment of the present invention, a rotating wheel is sleeved on the coaxial opposite side of the three-stage transmission wheel, and multiple annular tension grooves are arranged on it in sequence, with tension ropes wound around the upper and lower ends respectively, which can be tightened and retracted as the three-stage transmission wheel rotates to unlock.

[0010] As a preferred embodiment of the present invention, the first anti-theft mechanism is attached to the inside of the cabinet door, and a handle is attached to the outside of the corresponding cabinet door. A lock cylinder is inserted at the top of the handle, and a key is inserted therein for immediate unlocking of the cabinet door.

[0011] As a preferred embodiment of the present invention, a warning switch is suspended on the reset block on the coaxial side of the three-stage transmission wheel, which can close and close the three-color warning light when the three-stage transmission wheel is rotated to unlock.

[0012] As a preferred embodiment of the present invention, the first anti-theft mechanism has a built-in battery and is powered independently, allowing it to operate for extended periods even when the external power supply to the transformer cabinet is disconnected.

[0013] As a preferred embodiment of the present invention, the multi-stage transmission wheels are coaxially arranged with alternating large and small planets for high-precision transmission over a small range.

[0014] As a preferred embodiment of the present invention, the edge of the U-shaped opening near the latch is shorter than the edge away from the latch, which is used for the reset self-locking of the first anti-theft mechanism.

[0015] As a preferred embodiment of the present invention, the interior of the reset trigger is hollowed out to reduce stress concentration from high-frequency unlocking strikes.

[0016] As a preferred embodiment of the present invention, the three-color indicator light is designed with red, yellow and blue segments, flashes in a normal cycle, and is connected to a remote server for alarm monitoring of the substation.

[0017] The beneficial effects of this invention are:

[0018] Using substations with burglar alarms in the business hall offers significant advantages, effectively addressing the shortcomings of existing substation technologies in this area. Firstly, the substation integrates a burglar alarm system, with a three-color warning light on the top of the cabinet directly linked to the burglar alarm components. When the burglar alarm components detect unauthorized opening or forced entry, the warning light immediately alerts the outside world with an audible and visual alarm, prompting staff to call the police. This real-time alert function avoids the problem of existing substations lacking alarm systems, which often fail to detect illegal damage promptly, thus effectively improving the security of the internal electrical equipment.

[0019] Secondly, the system's primary anti-theft mechanism employs a sophisticated multi-stage transmission design, utilizing a motor and multi-stage transmission wheels to achieve precise locking and unlocking operations. Upon authorized unlocking, the motor circuit is activated, driving the multi-stage transmission wheels to rotate sequentially, from the first-stage to the second and third-stage transmission wheels, ensuring a stable and precise transmission process and guaranteeing reliable opening of the cabinet door. In the locked state, the locking device and reset trigger maintain the locked state through the linkage of the locking and reset torsion springs. Neither external force nor abnormal vibration of the cabinet door can easily damage this multi-stage locking structure, ensuring a strong lock on the cabinet door. This enhances the substation's resistance to damage, allowing it to maintain a stable locked state even under unauthorized operation, effectively preventing accidental unlocking under external interference.

[0020] Subsequently, in the design of this anti-theft structure, the linkage between the reset trigger, reset block, and locking device is achieved through a reset torsion spring and a locking torsion spring. When the transmission wheel is unlocked, the reset block on the three-stage transmission wheel rotates under the action of the motor, pushing the reset trigger. This causes the locking device to release its locking state clockwise with the rotation of the torsion spring and automatically disengage the bolt, enabling the cabinet door to open smoothly. This not only ensures smooth opening of the cabinet door in the unlocked state but also avoids accidental locking and unlocking caused by human error due to the natural locking action of the torsion spring's reset. This design optimizes the operational stability of locking and unlocking, ensuring that operators have a smooth unlocking experience and improving the safety and convenience of operation.

[0021] Furthermore, the anti-theft component utilizes a contact structure with guide plates and levers for motor circuit control during unlocking. Through precise engagement of the guide plates and levers, when the unlocking mechanism rotates to a specific position, the contacts connect to the guide plate, and the motor begins to drive the multi-stage transmission wheels. This process achieves efficient control of the transmission system, enabling the unlocking mechanism to start the motor when it reaches the preset position, saving power and improving system reliability. It also allows for accurate unlocking control, reducing security risks caused by improper operation and circuit failures.

[0022] In summary, this anti-theft alarm system not only overcomes the shortcomings of traditional substations in terms of anti-theft alarm functionality, but also achieves high-precision locking and unlocking through multi-stage transmission wheels and precise motor circuit control. This ensures safe opening of equipment under specific circumstances and provides strong locking in abnormal situations. The linkage alarm mechanism between the three-color warning lights and the anti-theft components further enhances the security of the cabinet, effectively preventing unauthorized damage and unauthorized opening. It provides a reliable protection system for the substations in the business hall, effectively ensuring the safe operation of power equipment and the normal operation of the business hall.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] Example 1

[0037] To address the technical problems in the background section, the following is provided: A substation with burglar alarm function for business halls:

[0038] Combination Figure 1 As shown, the business hall uses a transformer cabinet 1 with anti-theft alarm function, which includes a cabinet body 11 vertically erected and a cabinet door 12 hinged and rotated on it. A three-color warning light 5 is mounted on the top of the cabinet body 11. An anti-theft component 4 is embedded in the middle edge of the cabinet door 12, which includes a first anti-theft mechanism 41 and a second anti-theft mechanism 43, and is connected to the three-color warning light 5. The first anti-theft mechanism 41 is equipped with an unlocking mechanism 3. The first anti-theft component 4 is characterized by having a square lock shell 411 wrapped around its outer periphery. A middle plate 416 is inserted inside the lock shell 411. A motor 412 with contacts 4121 is longitudinally fixed at the front end of the middle plate 416. A conductive plate 4122 is mounted on its side. The rotating part of the motor 412 is staggered with a first-stage transmission wheel 413, and a second-stage transmission wheel 414 and a third-stage transmission wheel 413 are arranged through step-by-step coupling. 15. For precise transmission of the transmission system, the multi-stage transmission wheels are all transversely mounted on the middle plate 416. The three-stage transmission wheel 415 is coaxially fitted with a reset block. The rear end of the middle plate 416 is screwed with a torch-shaped reset trigger 417 and a locking device 418 tightly fastened to it. The locking device 418 has a U-shaped opening that mates with the locking tongue 42 embedded on the edge of the cabinet 11. The reset trigger 417 is pressed with a reset torsion spring 4171, and the locking device 418 is pressed with a locking torsion spring 4181 for resetting and locking the reset trigger 417 and the locking device 418. The contact point 4121 is suspended with a lock cylinder 31. The lock cylinder 31 is attached to the bottom of the wing-shaped lock spring 32. The bottom front end of the lock spring 32 is extended with a guide plate 322, and the rear end is attached with an elastic paddle 321 for connecting the motor 412 circuit to unlock when rotating.

[0039] The first anti-theft mechanism 41 is divided into a locked state and an unlocked state. In the unlocked state, the motor 412 stops, the multi-stage transmission wheel is locked, and the locking device 418 continues to rotate through the locking torsion spring 4181 and maintains the locked position with the help of the reset trigger 417 of the reset torsion spring 4171, locking the latch 42 on the cabinet 11. In the unlocked state, the unlocking mechanism 3 rotates, and the guide plate 322 and the lever 321 on it respectively connect the contact 4121 and the guide plate 4122. The motor 412 starts, and the multi-stage transmission wheel rotates in sequence. The reset block on the third-stage transmission wheel 415 rotates clockwise, pushing the reset trigger 417 to rotate. The locking device 418 unlocks clockwise with the locking torsion spring 4181 and releases the latch 42.

[0040] Firstly, the substation 1 integrates an anti-theft and alarm system. The tri-color warning light 5 on the top of the cabinet 11 is directly linked to the anti-theft component 4. Through this technical solution, when the anti-theft component 4 detects abnormal opening or forced entry of the cabinet door 12, the warning light will immediately issue an audible and visual alarm, alerting staff to call the police. This real-time warning function avoids the problem of existing substation 1 systems lacking alarm systems, which prevent timely detection of illegal damage, thus effectively improving the security of its internal electrical equipment.

[0041] Secondly, the first anti-theft mechanism 41 of the system adopts a precise multi-stage transmission design, using a motor 412 and multi-stage transmission wheels to achieve precise locking and unlocking operations. After authorized unlocking, the motor 412 circuit is connected, driving the multi-stage transmission wheels to rotate sequentially, from the first-stage transmission wheel 413 to the second-stage and third-stage transmission wheels 415, making the transmission process stable and precise, thereby ensuring the reliable opening of the cabinet door 12. In the locked state, the locking device 418 and the reset trigger 417 maintain the locked state through the linkage of the locking torsion spring 4181 and the reset torsion spring 4171. Whether it is external force damage or abnormal vibration of the cabinet door 12, it is difficult to damage this multi-stage locking structure, ensuring the strong locking of the cabinet door 12. This improves the anti-vandalism performance of the substation 1, enabling the substation 1 to maintain a stable locked state when subjected to illegal operation, effectively preventing accidental unlocking under external interference.

[0042] Subsequently, in the design of this anti-theft structure, the linkage between the reset trigger 417, the reset block, and the locking device 418 is achieved through the reset torsion spring 4171 and the locking torsion spring 4181. When the transmission wheel is unlocked, the reset block on the third-stage transmission wheel 415 rotates under the action of the motor 412, pushing the reset trigger 417. This causes the locking device 418 to release its locking state clockwise with the rotation of the torsion spring and automatically disengage the latch 42, enabling the cabinet door 12 to open smoothly. This not only ensures the smooth opening of the cabinet door 12 in the unlocked state but also avoids accidental locking and unlocking caused by human error due to the natural locking action of the torsion spring reset. This design optimizes the operational stability of locking and unlocking, ensuring that operators can obtain a smooth unlocking experience and improving the safety and convenience of operation.

[0043] Furthermore, the anti-theft component 4 utilizes a contact structure 4121 between the guide plate 322 and the lever 321 for motor 412 circuit control during unlocking. Through precise engagement of the guide plate 322 and the lever 321, when the unlocking mechanism 3 rotates to a specific position, the contact 4121 connects to the guide plate 4122, and the motor 412 begins to drive the multi-stage transmission wheels. This process achieves efficient control of the transmission system, enabling the unlocking mechanism 3 to start the motor 412 when it reaches the preset position, saving power and improving system reliability. It also allows for accurate unlocking control, reducing security risks caused by improper operation and circuit failures.

[0044] In summary, the design of this anti-theft alarm system not only compensates for the shortcomings of traditional transformer cabinet 1 in terms of anti-theft alarm functions, but also achieves high-precision locking and unlocking effects through multi-stage transmission wheels and precise motor 412 circuit control, ensuring safe opening of equipment under specific circumstances and providing strong locking in abnormal situations. The linkage alarm mechanism between the three-color warning light 5 and the anti-theft component 4 further enhances the security of cabinet 11, effectively preventing unauthorized personnel from damaging or opening it, providing a reliable protection system for transformer cabinet 1 in the business hall, and effectively ensuring the safe operation of power equipment and the normal operation of the business hall.

[0045] Example 2

[0046] like Figure 2 As shown, based on the above embodiments, this embodiment further provides the following:

[0047] In this embodiment, the second anti-theft mechanism 43 includes a base plate 431 symmetrically attached to the inner side of the cabinet door 12 and a fixed post 435 embedded in the side of the cabinet body 11. A hollow cylinder 432 with a through tension hole 4321 is mounted on the base plate 431, and a cylindrical locking bolt 434 is inserted axially along the tension hole 4321. A tension rope 44 is sleeved at the tail end of the bolt 4321. A disc-shaped limiter 4341 is provided around the locking bolt 434. A spring 433 is sleeved on the locking bolt 434 section between the limiter 4341 and the hollow cylinder 432, which can be squeezed and stretched axially. The fixed post 435 has a bolt hole 4351 adapted to the locking bolt 434 for immediate locking of the second anti-theft mechanism 43.

[0048] The three-stage transmission wheel 415 is fitted with a rotating wheel 419 on the opposite side of the coaxial axis. Multiple annular tension grooves 4191 are arranged on the wheel, and tension ropes 44 are wound around the upper and lower ends of the wheel respectively. The locking bolt 434 can be tightened and retracted synchronously with the rotation of the three-stage transmission wheel 415 to unlock.

[0049] Through the aforementioned technical means, the second anti-theft mechanism 43 is cleverly designed to increase the anti-theft security of the transformer cabinet 1, overcoming the shortcomings of traditional transformer cabinet 1's simple anti-theft structure and insufficient reliability. Firstly, by arranging symmetrical base plate 431 structures and hollow cylinders 432 on the inner side of the cabinet door 12, embedding cylindrical locking bolts 434, and cooperating with springs 433 and bolt holes 4351, the locking bolts 434 can be automatically locked when the cabinet door 12 is closed. Because the cylindrical locking bolts 434 are supported by springs 433, even if the cabinet 11 is subjected to external vibration, it is difficult to open. Springs 433 not only improve the locking's firmness but also enhance the system's durability, allowing the anti-theft device to maintain the reliability of its locking function even during long-term use.

[0050] Secondly, the coaxially arranged three-stage transmission wheel 415 and multiple annular tension grooves 4191 further enhance the functionality of the anti-theft system. The coordinated operation of the three-stage transmission wheel 415 and the rotating wheel 419 results in higher precision and sensitivity in the unlocking operation. By winding the tension rope 44 around the multiple tension grooves 4191 of the rotating wheel 419, the tension rope 44 at both ends can be tightened synchronously when the cabinet door 12 is unlocked. This design ensures that the locking bolt 434 retracts smoothly during the unlocking process, and in the locked state, the locking bolt 434 is firmly inserted into the bolt hole 4351, thereby effectively locking the cabinet door 12. The multiple tension grooves 4191 design provides independent tension adjustment, making the tightening and releasing process of the locking bolt 434 more precise and smooth, avoiding frequent malfunctions caused by uneven tension of the tension rope 44 in traditional structures. This synchronous tightening design can also effectively prevent wear and tear and detachment of the tension rope 44 during use, extending the service life of the system.

[0051] Furthermore, the tension of the elastic cord 44, combined with the rotation of the three-stage transmission wheel 415, ensures that the unlocking operation and the locking state of the cabinet 11 are highly consistent. Each rotation of the three-stage transmission wheel 415 corresponds to the tightening or loosening of the elastic cord 44, thereby achieving synchronous control of the locking bolt 434. This mechanism makes the unlocking and locking actions of the entire anti-theft system more flexible and stable, eliminating the need for manual adjustment and enhancing the system's automation performance. In public places such as business halls, the transformer cabinet 1 is frequently used, and this structure can maintain a stable locking state during daily switching operations, preventing the cabinet door 12 from being accidentally opened under external force.

[0052] In summary, the second anti-theft mechanism 43, combining a spring 433, a cylindrical locking bolt 434, and multiple tensioning grooves 4191, not only increases the locking strength and unlocking accuracy but also achieves automatic tension control. This multi-layered and multi-dimensional design of the anti-theft structure greatly enhances the anti-theft effect, ensuring the safety of the transformer cabinet 1 even in complex public spaces. It significantly improves the security level of the transformer cabinet 1 in the business hall, providing more comprehensive security for the internal power facilities.

[0053] Example 3

[0054] like Figure 2 As shown, based on the above embodiments, this embodiment further provides the following:

[0055] In this embodiment, the first anti-theft mechanism 41 is attached to the inside of the cabinet door 12, and a handle 2 is attached to the outside of the corresponding cabinet door 12. A lock cylinder 31 is inserted at the upper end of the handle 2, and a key 33 is inserted therein for immediate opening of the cabinet door 12.

[0056] A warning switch is suspended on the reset block on the opposite side of the coaxial third-stage transmission wheel 415, which can close and turn off the three-color warning light 5 when the third-stage transmission wheel 415 is rotated to unlock.

[0057] The three-color indicator light is designed with red, yellow and blue segments, flashes in a normal cycle, and is connected to a remote server for alarm monitoring of substation 1.

[0058] The above technical solution significantly improves the alarm capability of substation 1 in the event of unauthorized opening or damage, solving the problem of the inability of substation 1 in the business hall to provide an immediate alarm in traditional technologies. Specifically, during the rotation of the three-stage transmission wheel 415, the reset block and the warning switch are linked to ensure that the three-color warning light 5 illuminates promptly in the event of unauthorized unlocking. The warning light uses red, yellow, and blue indicators to emit different flashing signals according to different states, ensuring that staff can clearly identify abnormal situations. This design not only improves the sensitivity of the alarm but also intuitively displays the current safety status of substation 1 through color differentiation, facilitating rapid response.

[0059] Furthermore, the constant flashing design of the warning lights ensures that transformer cabinet 1 provides continuous safety alerts during normal operation, preventing the safety status of cabinet 11 from being overlooked due to prolonged unattended operation. In the event of an anomaly, the warning lights, connected to a remote server, can transmit alarm information to management personnel or the monitoring system in real time, enabling remote alarm and monitoring. This allows staff in the business hall to receive immediate notification of any abnormalities in transformer cabinet 1, enabling timely intervention and effectively preventing more serious losses due to delayed problem detection.

[0060] In summary, this anti-theft alarm design, through the organic integration of warning lights, transmission system and remote server, not only enhances the security protection capability of substation 1, but also improves the real-time performance and accuracy of the alarm, providing more reliable security for the business hall and ensuring that power equipment can be quickly responded to and dealt with when illegally intruded.

[0061] Example 4

[0062] like Figure 2 As shown, based on the above embodiments, this embodiment further provides the following:

[0063] In this embodiment, the first anti-theft mechanism 41 has a built-in battery 4123, which is independently powered and can work for a long time when the external power supply of the transformer cabinet 1 is disconnected.

[0064] The multi-stage transmission wheels are coaxially arranged with alternating large and small planetary configurations, used for high-precision transmission over a small area.

[0065] The edge of the U-shaped opening near the latch 42 is shorter than the edge away from the latch 42, and is used for the reset self-locking of the first anti-theft mechanism 41.

[0066] The reset trigger 417 has a hollow design inside to reduce stress concentration from high-frequency unlocking strikes.

[0067] The above technical solutions significantly improve the security of the substation 1 in the business hall, solving the problem of insufficient anti-theft capabilities in existing technologies. Firstly, it adopts an independent power supply system with a built-in battery 4123, ensuring the anti-theft mechanism of substation 1 continues to operate even when the external power supply is disconnected or damaged, thus ensuring the reliability and continuity of the anti-theft system. Secondly, the multi-stage transmission wheels of substation 1 use a coaxial planetary gear staggered arrangement design, enabling high-precision transmission in a confined space, effectively reducing errors and wear in mechanical transmission, minimizing space occupation, and enhancing the working stability and precision of the anti-theft mechanism. Simultaneously, the special design of the U-shaped opening allows the locking tongue 42 to automatically lock upon reset, avoiding the problem of the locking tongue 42 loosening due to human interference or mechanical failure, further enhancing the anti-theft effect. The hollow design of the reset trigger 417 effectively reduces stress concentration that may occur due to frequent unlocking operations, extending the service life of the anti-theft mechanism and improving its maintenance-free performance. These innovative structural designs not only improve the precision and stability of the anti-theft system, but also enhance the resistance of the transformer cabinet 1 to damage in harsh environments, effectively ensuring the security of the transformer cabinet 1 in the business hall, reducing the harm of external illegal interference to the internal equipment of the transformer cabinet 1, and greatly improving the security protection capability of the business hall equipment.

[0068] Working principle and usage process of this invention:

[0069] First, close the cabinet door 12 and confirm that the anti-theft component 4 is locked. At this time, the multi-stage transmission wheel on the cabinet 11 is locked, and the locking device 418 rotates under the action of the locking torsion spring 4181, driving the reset torsion spring 4171 to fix the reset trigger 417 in the locked position, thereby ensuring that the lock tongue 42 firmly locks the cabinet door 12, achieving the initial anti-theft state. The three-color warning light 5 flashes continuously in a cycle on the top of the cabinet 11, usually displaying red, yellow, and blue colors in sequence, indicating that the transformer cabinet 1 is in a safety monitoring state, and is monitored in real time through a connected remote server.

[0070] When unlocking is required, key 33 is inserted into lock cylinder 31 and rotated to the unlock position. The unlocking rotation triggers guide plate 322 and lever 321 to contact contact point 4121 and conductive guide plate 4122 of motor 412, thereby connecting the motor 412 circuit and starting motor 412. As motor 412 runs, the drive transmission system begins to transmit power step by step, with multi-stage transmission wheels rotating sequentially to gradually transmit power to the third-stage transmission wheel 415. The reset block, coaxially sleeved on the third-stage transmission wheel 415, begins to rotate clockwise, thereby pushing the reset trigger 417 to rotate, causing the locking device 418 to gradually release the locking torsion spring 4181 from its locked state. As the locking device 418 rotates to the unlock position, the latch 42 on cabinet door 12 disengages from the U-shaped opening, at which point cabinet door 12 can be opened, completing the initial unlocking.

[0071] During the unlocking process, the reset block on the opposite side of the three-stage transmission wheel 415 drives the warning switch to operate synchronously, causing the three-color warning light 5 to stop flashing, indicating that the cabinet door 12 is unlocked. At this time, the unlocking mechanism 3 also applies a rotational action to the coaxially mounted rotating wheel 419 through the three-stage transmission wheel 415, causing the tension rope 44 wound in the tension groove 4191 to tighten and retract the locking bolt 434 into the hollow cylinder 432, so that the cylindrical locking bolt 434 on the base plate 431 located inside the cabinet door 12 exits from the bolt hole 4351 of the fixed stake 435. The second anti-theft mechanism 43 unlocks simultaneously, ensuring that the cabinet door 12 is completely unlocked and that no anti-theft locking components are stuck.

[0072] After cabinet door 12 is opened, staff can perform operations and maintenance on the inside of cabinet 11. After the operation is completed and cabinet door 12 is closed, the unlocking mechanism 3 and the reset trigger 417 gradually return to their initial locked state under the elastic force of the locking torsion spring 4181 and the reset torsion spring 4171. At the same time, the tri-color warning light 5 resumes its normal flashing state, reminding the monitoring system that cabinet 11 has been relocked and normal monitoring has resumed.

[0073] When the power is disconnected, the anti-theft component 4 can be powered by the built-in independent battery 4123 to ensure the continuous operation of the anti-theft alarm system. Even without external power supply, the transformer cabinet 1 can still ensure the normal operation of key components such as the transmission system, reset trigger 417, and locking device 418 through the built-in battery 4123, thereby ensuring that the cabinet door 12 is securely locked and the alarm monitoring continues.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
