Description

Technical Field

[0001] The invention belongs to the technical field of transformer cabinets, and in particular relates to a transformer cabinet with an anti-theft alarm function for a business hall. Background Art

[0002] With the popularization and improvement of the intelligence of modern power systems, substations play an indispensable role in the process of power transmission and distribution, and are widely used in various places. However, in public areas such as business halls, the anti-theft and safety issues of substations have gradually emerged. In particular, with the continuous increase in the types of business in business halls and the dense layout of power equipment, the electrical components and control circuits in the substations have also risen in value. They are not only of high value, but also related to the normal operation of the business hall. If they are damaged or illegally invaded, it may cause equipment damage, business stagnation, or even more serious safety accidents. Therefore, anti-theft protection of substations in business halls is particularly necessary.

[0003] Existing substation cabinets usually focus on the transmission and control functions of the power system. The structural design of the cabinet itself is relatively simple, and no special design is made for anti-theft and alarm functions. Conventional substation cabinet door locks mainly rely on simple mechanical lock structures, and the cabinet doors are opened and closed manually. However, such mechanical lock structures are easy to be damaged, and illegal personnel can enter the cabinet by prying the lock with external force or tools, which makes the substation cabinet have a great safety hazard. In addition, the ordinary mechanical lock design is not connected to the alarm system. Even if the lock is damaged or the cabinet door is illegally opened, it is impossible to issue an alarm in time to notify relevant personnel, and it is impossible to play an effective safety precaution role. Therefore, the substation cabinets in the prior art lack the necessary anti-theft alarm measures in public places, especially in business halls, which can easily lead to criminals stealing or destroying power equipment and affecting the normal operation of the power system.

[0004] In response to the above problems, some technical solutions have begun to try to introduce new lock structures such as electronic locks and password locks. However, these technical solutions often focus on the structural optimization of the lock itself, but fail to effectively combine the anti-theft lock with the alarm system, and cannot achieve real-time and intelligent anti-theft alarm. Even if some technical solutions have initially realized the anti-theft alarm function, their alarm methods are relatively simple and lack multi-level and multi-level security protection measures; at the same time, the sensitivity and response speed of existing alarm devices are limited, and they are prone to false alarms due to external environmental interference or operational errors. In addition, while realizing the alarm, traditional anti-theft alarm technology lacks a precise locking transmission system, and it is difficult to balance the smooth operation of unlocking and locking on the basis of ensuring safety and stability. It cannot meet the dual needs of high-frequency transmission and high safety in actual scenarios. Therefore, the design of a substation cabinet that integrates anti-theft, alarm, and precise unlocking has become an urgent need in the power equipment of the business hall and needs to be solved urgently. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a substation with an anti-theft alarm function for a business hall. The specific technical solution is as follows:

[0006] The present invention provides a substation cabinet with an anti-theft alarm function for a business hall, which comprises a cabinet door hinged and rotatably mounted on a vertically erected substation cabinet body, 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, which comprises a first anti-theft mechanism and a second anti-theft mechanism, and is connected to the three-color warning light, and an unlocking mechanism is inserted in the first anti-theft mechanism, characterized in that a square lock shell is wrapped around the outer periphery of the first anti-theft component, a middle plate is inserted in the lock shell, a motor with contacts is longitudinally fixed to the front end of the middle plate, a power-carrying guide plate is mounted on the side, and a primary transmission wheel is staggeredly arranged on the rotating part of the motor, and a secondary transmission wheel is arranged through a step-by-step coupling connection. Wheel and three-stage transmission wheel are used for accurate transmission of the transmission system. The multi-stage transmission wheels are all transversely penetrated on the middle plate. A reset block is coaxially sleeved on the three-stage transmission wheel. A torch-shaped reset trigger and a locker tightly buckled therewith are spun on the middle plate at the rear end thereof. The locker has a U-shaped opening for docking with a lock tongue embedded in the edge of the cabinet. A reset torsion spring is pressed on the reset trigger, and a locking torsion spring is pressed on the locker for resetting and locking the reset trigger and the locker. A lock core is suspended on the contact, and a wing-shaped lock spring is attached under the lock core. A guide piece is extended from the front end of the bottom of the lock spring, and an elastic paddle is attached to the rear end thereof for connecting the motor circuit to unlock when rotating;

[0007] The first anti-theft mechanism is divided into a locked state and an unlocked state. In the unlocked state, the motor stops, the multi-stage transmission wheel is locked, the locker continues to rotate through the locking torsion spring, and is kept in the locked position by the reset trigger of the reset torsion spring, locking the lock tongue on the cabinet. In the unlocked state, the unlocking mechanism rotates, the guide piece and the paddle thereon are respectively connected to the contact and the guide plate, the motor starts, the multi-stage transmission wheel rotates step by step in sequence, the reset block on the three-stage transmission wheel rotates clockwise, pushing the reset trigger to rotate, the locker is unlocked clockwise along with the locking torsion spring, and the lock tongue is withdrawn.

[0008] As a preferred technical solution 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 stake embedded in the side of the cabinet body, a hollow cylinder with an elastic hole passing through it is mounted on the base plate, and a cylindrical locking bolt is inserted axially along the elastic hole, and an elastic rope is sleeved on the tail end of the cylindrical locking bolt along the elastic hole, a disc-shaped limiter is provided on the locking bolt, and 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, and a bolt hole compatible with the locking bolt is opened on the fixed stake for instant locking of the second anti-theft mechanism.

[0009] As a preferred technical solution of the present invention, the coaxial opposite sides of the three-stage transmission wheel are provided with the same rotating wheel, on which a plurality of annular elastic grooves are arranged in sequence, and elastic ropes are respectively coiled at the upper and lower ends thereof, which can be synchronously tightened and retracted when the three-stage transmission wheel rotates to unlock.

[0010] As a preferred technical solution of the present invention, the first anti-theft mechanism is attached to the inner side of the cabinet door, and the corresponding outer side of the cabinet door is attached with a handle, the upper end of which is penetrated by a lock core, in which a key is inserted for instant unlocking of the cabinet door.

[0011] As a preferred technical solution of the present invention, a warning switch is suspended on the reset block on the coaxial opposite side of the three-stage transmission wheel, which can close and turn off the three-color warning light when the three-stage transmission wheel rotates and unlocks.

[0012] As a preferred technical solution of the present invention, the first anti-theft mechanism has a built-in battery and adopts an independent power supply, and can work for a long time when the external power supply of the transformer cabinet is disconnected.

[0013] As a preferred technical solution of the present invention, the multi-stage transmission wheel is a coaxial large and small planetary wheel arranged alternately, which is used for high-precision transmission in a small range.

[0014] As a preferred technical solution of the present invention, the edge of the U-shaped opening close to the lock tongue is shorter than the edge away from the lock tongue, which is used for resetting and self-locking of the first anti-theft mechanism.

[0015] As a preferred technical solution of the present invention, the interior of the reset trigger is hollowed out to reduce stress concentration caused by high-frequency unlocking knocks.

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

[0017] The beneficial effects of the present invention are:

[0018] The substation with anti-theft alarm function used in the business hall has significant beneficial effects and can effectively make up for the deficiencies of the substation in the anti-theft alarm in the prior art. First of all, the substation integrates the anti-theft and alarm system, and the three-color warning light on the top of the cabinet is directly linked to the anti-theft component. When the anti-theft component detects abnormal opening of the cabinet door or violent vandalism, the warning light will immediately warn the outside world through sound and light alarm, thereby reminding the staff to complete the alarm. This real-time warning function avoids the problem that the existing substation cannot be discovered in time after being illegally damaged because it is not equipped with an alarm system, thereby effectively improving the safety of its internal power equipment.

[0019] Secondly, the first anti-theft mechanism of the system adopts a sophisticated multi-stage transmission design, using a motor and a multi-stage transmission wheel to achieve precise locking and unlocking operations. After authorized unlocking, the motor circuit is connected, and drives the multi-stage transmission wheel to rotate step by step, from the first stage transmission wheel to the second stage and the third stage transmission wheel, so that the transmission process is stable and accurate, thereby ensuring the reliable opening of the cabinet door. In the locked state, the locker and the reset trigger are kept in a locked state through the linkage of the locking torsion spring and the reset torsion spring. Whether it is external force damage or abnormal vibration of the cabinet door, it is difficult to destroy this multi-stage locking structure, ensuring the strong locking of the cabinet door, which improves the anti-destruction performance of the substation cabinet, so that the substation cabinet can maintain a stable locked state when it is illegally operated, and effectively prevents accidental unlocking under external interference.

[0020] Then, in the design of the anti-theft structure, the linkage between the reset trigger, reset block and lock is achieved through the reset torsion spring and the locking torsion spring. When the transmission wheel is unlocked, the reset block on the three-stage transmission wheel rotates and pushes the reset trigger under the action of the motor, so that the locker is unlocked clockwise as the torsion spring rotates, and the lock tongue is automatically withdrawn to achieve the smooth opening of the cabinet door. This not only ensures the smooth opening of the cabinet door in the unlocked state, but also relies on the natural locking action of the torsion spring reset to avoid accidental locking and opening caused by human operation errors. This design optimizes the operational stability of locking and unlocking, ensures that the operator can get a smooth unlocking experience when unlocking, and improves the safety and convenience of operation.

[0021] In addition, the contact structure of the guide plate and the paddle is used in the anti-theft component for motor circuit control during unlocking. Through the precise docking of the guide plate and the paddle, when the unlocking mechanism rotates to a specific position, the contact connects the guide plate and the motor starts to drive the multi-stage transmission wheel to operate. This process realizes efficient control of the transmission system, allowing the unlocking mechanism to start the motor when it reaches the preset position, saving electricity and improving the reliability of the system. It can accurately control the unlocking and reduce safety hazards caused by improper operation and circuit failure.

[0022] In summary, the design of this anti-theft alarm system not only makes up for the shortcomings of traditional substation cabinets in terms of anti-theft alarm function, but also achieves high-precision locking and unlocking effects through multi-stage transmission wheels and precise motor circuit control, ensuring the safe opening of the equipment under specific circumstances, while providing strong locking under abnormal circumstances. The linkage alarm mechanism of the three-color warning light and the anti-theft component further improves the safety of the cabinet, effectively preventing damage and unauthorized opening by unauthorized personnel, providing a reliable protection system for the substation cabinet in the business hall, and effectively ensuring the safe operation of power equipment and the normal operation of the business hall.

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Embodiment 1

[0037] In order to solve the technical problems in the background technology, the following substation cabinet 1 with anti-theft alarm function for use in a business hall is provided:

[0038] Combination Figure 1 As shown, a substation cabinet 1 with an anti-theft alarm function is used in a business hall, which includes a cabinet door 12 hingedly rotatably mounted on a cabinet body 11 of the vertically erected substation cabinet 1, a three-color warning light 5 is mounted on the top of the cabinet body 11, an anti-theft component 4 is embedded at 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 inserted with an unlocking mechanism 3, and is characterized in that a square lock shell 411 is wrapped around the outer periphery of the first anti-theft component 4, a middle plate 416 is inserted in the lock shell 411, a motor 412 with a contact 4121 is longitudinally fixed at the front end of the middle plate 416, a power-carrying guide plate 4122 is mounted on the side, and a primary transmission wheel 413 is staggeredly arranged on the rotating part of the motor 412, and a secondary transmission wheel 414 and a tertiary transmission wheel 414 are arranged through step-by-step coupling connection. 15, used for accurate transmission of the transmission system, the multi-stage transmission wheels are all transversely penetrated on the middle plate 416, the three-stage transmission wheel 415 is coaxially sleeved with a reset block, and a torch-shaped reset trigger 417 and a lock 418 tightly buckled therewith are spun on the middle plate 416 at the rear end thereof, the lock 418 has a U-shaped opening for docking with a lock tongue 42 embedded in the edge of the cabinet 11, the reset trigger 417 is pressed with a reset torsion spring 4171, and the lock 418 is pressed with a locking torsion spring 4181, which is used for resetting and locking the reset trigger 417 and the lock 418, the contact 4121 is suspended with a lock core 31, and a wing-shaped lock spring 32 is attached under the lock core 31, a guide piece 322 is extended from the bottom front end of the lock spring 32, and an elastic paddle 321 is attached to the rear end thereof, which is used 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, the locker 418 continues to rotate through the locking torsion spring 4181, and is kept in the locked position by the reset trigger 417 of the reset torsion spring 4171, locking the lock tongue 42 on the cabinet 11. In the unlocked state, the unlocking mechanism 3 rotates, and the guide piece 322 and the paddle 321 thereon are respectively connected to the contact 4121 and the guide plate 4122, the motor 412 starts, the multi-stage transmission wheel rotates step by step in sequence, and the reset block on the three-stage transmission wheel 415 rotates clockwise, pushing the reset trigger 417 to rotate, and the locker 418 is unlocked clockwise with the locking torsion spring 4181, and the lock tongue 42 is withdrawn.

[0040] First, the substation cabinet 1 integrates an anti-theft and alarm system, and the three-color warning light 5 on the top of the cabinet body 11 is directly linked to the anti-theft component 4. Through the above technical solution, when the anti-theft component 4 detects abnormal opening or violent destruction of the cabinet door 12, the warning light will immediately warn the outside world through sound and light alarms, thereby reminding the staff to complete the alarm. This real-time warning function avoids the problem that the existing substation cabinet 1 cannot be discovered in time after being illegally damaged because it is not equipped with an alarm system, thereby effectively improving the safety of its internal power equipment.

[0041] Secondly, the first anti-theft mechanism 41 of the system adopts a precise multi-stage transmission design, using a motor 412 and a multi-stage transmission wheel to achieve precise locking and unlocking operations. After the unlocking is authorized, the motor 412 circuit is connected, and drives the multi-stage transmission wheel to rotate step by step, from the first-stage transmission wheel 413 to the second-stage and third-stage transmission wheels 415, so that the transmission process is stable and accurate, thereby ensuring the reliable opening of the cabinet door 12. In the locked state, the locker 418 and the reset trigger 417 are kept in a 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 destroy this multi-stage locking structure, ensuring the strong locking of the cabinet door 12, which improves the anti-destruction performance of the substation cabinet 1, so that the substation cabinet 1 can maintain a stable locked state when it is illegally operated, and effectively prevents the accidental unlocking under external force interference.

[0042] Then, in the design of the anti-theft structure, the linkage between the reset trigger 417 and the reset block and the lock 418 is realized through the reset torsion spring 4171 and the locking torsion spring 4181. When the transmission wheel is unlocked, the reset block on the three-stage transmission wheel 415 rotates and pushes the reset trigger 417 under the action of the motor 412, so that the lock 418 is unlocked clockwise with the rotation of the torsion spring, and automatically withdraws the lock tongue 42, so that the cabinet door 12 is opened smoothly, which not only ensures the smooth opening of the cabinet door 12 in the unlocked state, but also relies on the natural locking action of the torsion spring reset to avoid the wrong locking and opening caused by human operation errors. This design optimizes the operational stability of locking and unlocking, ensures that the operator can get a smooth unlocking experience when unlocking, and improves the safety and convenience of operation.

[0043] In addition, the anti-theft component 4 uses the contact 4121 structure of the guide plate 322 and the paddle 321 for controlling the circuit of the motor 412 during unlocking. Through the precise docking of the guide plate 322 and the paddle 321, when the unlocking mechanism 3 rotates to a specific position, the contact 4121 connects to the guide plate 4122, and the motor 412 starts to drive the multi-stage transmission wheel to operate. This process realizes efficient control of the transmission system, so that the unlocking mechanism 3 can start the motor 412 when it reaches the preset position, saving electricity and improving the reliability of the system, and can accurately control the unlocking, reducing the safety hazards caused by improper operation and circuit failure.

[0044] In summary, the design of the anti-theft alarm system not only makes up for the deficiencies of the traditional substation cabinet 1 in terms of anti-theft alarm function, but also achieves high-precision locking and unlocking effects through multi-stage transmission wheels and precise motor 412 circuit control, ensuring the safe opening of the equipment under specific circumstances, while providing strong locking under abnormal circumstances. The linkage alarm mechanism of the three-color warning light 5 and the anti-theft component 4 further improves the safety of the cabinet 11, effectively preventing damage and unauthorized opening by unauthorized personnel, providing a reliable protection system for the substation cabinet 1 in the business hall, and effectively ensuring the safe operation of power equipment and the normal operation of the business hall.

[0045] Embodiment 2

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

[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 stake 435 embedded in the side of the cabinet body 11. A hollow cylinder 432 with an elastic hole 4321 penetrating therein is mounted on the base plate 431, and a cylindrical locking bolt 434 is axially inserted along the elastic hole 4321, and an elastic rope 44 is sleeved on the tail end of the cylindrical locking bolt 434 along the elastic hole 4321. A disc-shaped limiter 4341 is arranged around the locking bolt 434, and 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 along the axial direction, and a bolt hole 4351 matched with the locking bolt 434 is opened on the fixed stake 435 for instant locking of the second anti-theft mechanism 43.

[0048] The coaxial opposite side of the three-stage transmission wheel 415 is sleeved with a coaxial rotating wheel 419, on which a plurality of annular elastic grooves 4191 are arranged in sequence, and elastic ropes 44 are respectively coiled at the upper and lower ends thereof, which can be rotated and unlocked to synchronously tighten and retract the locking bolt 434.

[0049] Through the above-mentioned technical means, the design of the second anti-theft mechanism 43 cleverly increases the anti-theft security of the substation 1, and overcomes the defects of the traditional anti-theft structure of the substation 1 being single and unreliable. First, by arranging a symmetrical base plate 431 structure and a hollow cylinder 432 on the inner side of the cabinet door 12, embedding a cylindrical locking bolt 434 and cooperating with a spring 433 and a bolt hole 4351, the locking bolt 434 can be automatically locked when the cabinet door 12 is closed. Since the cylindrical locking bolt 434 is supported by the spring 433, it is difficult to be opened even if the cabinet body 11 is vibrated by external force. The spring 433 not only improves the firmness of the locking, but also enhances the durability of the system, so that the anti-theft device can still maintain the reliability of the locking function during long-term use.

[0050] Secondly, the coaxially arranged three-stage transmission wheel 415 and the multi-channel annular elastic groove 4191 design further enhance the function of the anti-theft system. The coordination between the three-stage transmission wheel 415 and the same rotating wheel 419 makes the unlocking operation more accurate and sensitive. By winding the elastic cord 44 in the multi-channel elastic groove 4191 of the same rotating wheel 419, the elastic cords 44 at the upper and lower ends can be tightened synchronously when the cabinet door 12 is unlocked. This design ensures that the locking bolt 434 can be smoothly retracted during the unlocking process, and the locking bolt 434 can be firmly inserted into the bolt hole 4351 in the locked state, thereby effectively locking the cabinet door 12. The multi-channel elastic groove 4191 design provides independent tension adjustment, making the tightening and releasing process of the locking bolt 434 more accurate and smooth, avoiding frequent failures caused by uneven tension of the elastic cord 44 in the traditional structure. This synchronous tightening design can also effectively prevent the elastic cord 44 from wearing and falling off during use, thereby improving the service life of the system.

[0051] In addition, the tightness of the elastic cord 44 is combined with the rotation of the three-stage transmission wheel 415, so that the unlocking operation is highly consistent with the locking state of the cabinet 11. Each rotation of the three-stage transmission wheel 415 corresponds to the tightening or loosening of the elastic cord 44, thereby realizing the 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, without the need for manual adjustment, and enhances the automation performance of the system. In public places such as business halls, the substation cabinet 1 is frequently used, and this structure can maintain a stable locking state during daily switch operations, preventing the cabinet door 12 from being opened by mistake under the action of external forces.

[0052] In summary, the second anti-theft mechanism 43 is designed with a spring 433, a cylindrical locking bolt 434 and multiple tension grooves 4191, which not only increases the firmness of locking and the accuracy of unlocking, but also realizes automatic adjustment of tension control. The multi-level and multi-dimensional design of the anti-theft structure greatly improves the anti-theft effect, so that the substation cabinet 1 can still ensure safety in complex public places, significantly improves the safety protection level of the business hall substation cabinet 1, and provides more comprehensive safety protection for internal power facilities.

[0053] Embodiment 3

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

[0055] In this embodiment, the first anti-theft mechanism 41 is attached to the inner side of the cabinet door 12, and the corresponding cabinet door 12 is attached to the outer side with a handle 2, the upper end of which is penetrated by a lock core 31, in which a key 33 is inserted for instant opening of the cabinet door 12.

[0056] A warning switch is suspended on the reset block on the coaxial opposite side of the three-stage transmission wheel 415, which can be closed and turned off the three-color warning light 5 when the three-stage transmission wheel 415 rotates and unlocks.

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

[0058] Through the above technical solution, the alarm capability of the substation 1 when it is illegally opened or damaged is greatly improved, and the problem that the substation 1 in the business hall cannot give an immediate alarm in the traditional technology is solved. Specifically, during the rotation of the three-stage transmission wheel 415, the reset block is linked with the warning switch to ensure that the three-color warning light 5 can light up in time when it is illegally unlocked. The warning light can emit different flashing signals according to different states through red, yellow and blue indications, ensuring that the 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 the substation 1 through color differentiation, which is convenient for quick response.

[0059] In addition, the normal flashing design of the warning light allows the transformer cabinet 1 to continue to provide safety reminders during normal operation, avoiding the neglect of the safety status of the cabinet 11 due to long-term unattended operation. When an abnormality occurs, the warning light can transmit the alarm information to the management personnel or the monitoring system in real time through the connection with the remote server, realizing remote alarm and monitoring. In this way, the staff of the business hall can be notified of the abnormality of the transformer cabinet 1 at the first time, so as to take timely treatment measures, effectively preventing more serious losses caused by failure to discover the problem in time.

[0060] In summary, this anti-theft alarm design, through the organic combination of warning lights, transmission systems and remote servers, not only enhances the security protection capability of the substation 1, but also improves the real-time and accuracy of the alarm, providing a more reliable security guarantee for the business hall, and ensuring that power equipment can be quickly responded to and handled when illegally invaded.

[0061] Embodiment 4

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

[0063] In this embodiment, the first anti-theft mechanism 41 has a built-in battery 4123 and uses an independent power supply, 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 coaxial large and small planets arranged alternately, and are used for high-precision transmission in a small range.

[0065] The edge of the U-shaped opening close to the lock tongue 42 is shorter than the edge away from the lock tongue 42 , and is used for resetting and self-locking of the first anti-theft mechanism 41 .

[0066] The interior of the reset trigger 417 is hollowed out to reduce stress concentration caused by high-frequency unlocking knocks.

[0067] Through the above technical scheme, the security of the business hall substation cabinet 1 is significantly improved, and the problem of insufficient anti-theft ability in the prior art is solved. First, it adopts an independent power supply system with a built-in battery 4123, so that the anti-theft mechanism of the substation cabinet 1 can continue to work when the external power supply is disconnected or damaged, thereby ensuring the reliability and sustainability of the anti-theft system. Secondly, the multi-stage transmission wheel of the substation cabinet 1 adopts a design of staggered coaxial planetary gears, which can achieve high-precision transmission in a small space, effectively reduce the error and wear in the mechanical transmission, reduce the space occupation, and enhance the working stability and precision of the anti-theft mechanism. At the same time, the special design of the U-shaped mouth enables the lock tongue 42 to be automatically locked when reset, avoiding the problem of the lock tongue 42 loosening caused by human interference or mechanical failure, and further enhancing the anti-theft effect. The hollow design of the reset trigger 417 effectively reduces the stress concentration that may be caused by frequent unlocking operations, prolongs the service life of the anti-theft mechanism and improves its maintenance-free performance. These innovative structural designs not only improve the precision and stability of the anti-theft system, but also enhance the anti-destruction ability of the substation 1 in harsh environments, effectively ensure the safety of the substation 1 in the business hall, reduce the harm of external illegal interference to the internal equipment of the substation 1, and greatly improve the safety protection capability of the equipment in the business hall.

[0068] The working principle and use process of the present invention:

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

[0070] When unlocking is required, the key 33 is inserted into the lock cylinder 31 and rotated to the unlocking position. The unlocking rotation action triggers the guide piece 322 and the paddle 321 to contact the contact 4121 of the motor 412 and the conductive guide plate 4122, thereby connecting the motor 412 circuit and starting the motor 412. As the motor 412 runs, the drive transmission system starts to transmit step by step, and the multi-stage transmission wheels rotate in sequence, gradually transmitting power to the three-stage transmission wheel 415. The reset block coaxially sleeved on the three-stage transmission wheel 415 starts to rotate clockwise, thereby pushing the reset trigger 417 to rotate, so that the locker 418 gradually releases the locking state of the locking torsion spring 4181. As the locker 418 rotates to the unlocking position, the lock tongue 42 on the cabinet door 12 disengages from the U-shaped opening, and the cabinet door 12 can be opened at this time, completing the preliminary unlocking.

[0071] During the unlocking process, the reset block on the coaxial opposite side of the three-stage transmission wheel 415 drives the warning switch to operate synchronously, so that the three-color warning light 5 stops 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 corotating wheel 419 through the three-stage transmission wheel 415, driving the elastic rope 44 wound in the elastic 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 on the inner side of the cabinet door 12 withdraws from the bolt hole 4351 of the fixed stake 435, and the second anti-theft mechanism 43 is unlocked synchronously, ensuring that the cabinet door 12 is completely unlocked without any anti-theft locking component being stuck.

[0072] After the cabinet door 12 is opened, the staff can operate and maintain the inside of the cabinet 11. After the operation is completed and the cabinet door 12 is closed, the unlocking mechanism 3 and the reset trigger 417 gradually return to the initial locking state under the elastic force of the locking torsion spring 4181 and the reset torsion spring 4171. At the same time, the three-color warning light 5 returns to the normal flashing state, reminding the monitoring system that the cabinet 11 has been re-locked and restored to the normal monitoring state.

[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. The transformer cabinet 1 can still ensure the normal operation of key components such as the transmission system, reset trigger 417, and locker 418 through the built-in battery 4123 without external power supply, thereby ensuring that the cabinet door 12 is firmly locked and the alarm monitoring is continuously performed.

[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 in the protection scope of the present invention.
