Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transformer technology, specifically a power transformer with alarm function. Background Technology
[0002] As a core piece of equipment in the power grid system, power transformers are often installed outdoors and face threats from theft, vandalism, and environmental factors. In the current technology, traditional transformers lack protective measures or use simple fences or enclosed enclosures, which have limited anti-theft capabilities and lack active alarm functions. Their mechanical locks are easily damaged or opened by technology.
[0003] For example, the authorized patent document with application number CN202323150345.9 discloses a power transformer with an oil leakage prevention function. This design has a simple structure. The oil is filtered through a filter screen and can be reused. A liquid level sensor detects the liquid level inside the oil leakage collection seat. When the liquid level inside the oil leakage collection seat rises, it indicates an oil leak, and an alarm is triggered. Oil can be replenished in time to avoid affecting the normal operation of the power transformer. It includes a power transformer with an oil filling port on the top. The top of the power transformer is connected to a bend pipe, and an oil replenishment mechanism is connected to the bend pipe. The bottom of the power transformer is equipped with an oil leakage collection seat. The oil leakage collection seat has a hollow structure and a filter screen is installed inside. The oil is filtered through the filter screen and can be reused. The oil replenishment mechanism is connected to the oil leakage collection seat. Two mounting brackets are symmetrically arranged at the bottom of the oil leakage collection seat. A rectangular limiting strip is fixedly installed on the top of the oil leakage collection seat.
[0004] The aforementioned patents have limited anti-theft capabilities and lack active alarm functions. Their mechanical locks are easily damaged or technically opened. Therefore, we need to provide a power transformer with an alarm function. Utility Model Content

Combined with an audible and visual alarm, it realizes real-time intrusion alarm, reducing the risk of theft. The inclined buckle and the elastic pin rod, together with the spring abutment, realize the locking self-reset function. The locking force is enhanced when damaged by external force. The pin rod requires a special key to trigger, which improves the anti-theft performance. This solves the problems mentioned in the background technology, such as limited anti-theft capability, lack of active alarm function, and easy damage or technical opening of mechanical locks.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-6 This utility model provides a technical solution: a power transformer with an alarm function, comprising:
[0028] Fence 1, and a protective box 2 with a roof installed inside fence 1;
[0029] The transformer body 3 is installed inside the protective box 2 via a mounting bracket. The surface of the protective box 2 is hinged with a cabinet door 4. An anti-theft lock mechanism 5 is installed between the protective box 2 and the cabinet door 4 for anti-theft purposes.
[0030] The inside of the fence 1 is equipped with an alarm mechanism 6 to protect the transformer body 3;
[0031] Specifically, the dual structure design of the fence 1 and the canopy-covered protective box 2 extends the transformer's lifespan. The infrared beam detector 61 and the monitoring probe 7 form a blind-spot-free monitoring system, which, combined with the audible and visual alarm 63, enables real-time intrusion alarms and reduces the risk of theft. The slanted buckle 51 and the elastic pin 54, along with the spring 552, achieve a self-resetting locking function, and the locking force is enhanced when damaged by external force. The pin 54 requires a special key to trigger, improving anti-theft performance.
[0032] In this embodiment, the fence 1 serves as the first line of defense, preventing unauthorized personnel or animals from easily approaching the transformer. It employs a spring-driven pin 54 and buckle 51 structure, automatically locking when the cabinet door 4 is closed. The transmitter 611 and receiver 612 of the infrared beam detector 61 are respectively installed on both sides of the fence 1, forming one or more invisible beam defense lines. When a person or object enters and blocks the infrared beam, an alarm signal is triggered. The alarm controller 62 receives the signal from the infrared detector and determines whether an alarm has been triggered. It can link the monitoring probe 7 to record video and activate the audible and visual alarm 63. When the cabinet door 4 is closed, the pin 54 automatically inserts into the slot 52 of the buckle 51 under the action of the spring 552, completing the locking and achieving self-locking. No manual locking is required; a special key must be inserted, and when the key is turned, the abutment rod 564 pushes the follower block 551, compressing the spring 552 and pulling out the pin 54 before the door can be opened.
[0033] The alarm mechanism 6 includes an infrared beam detector 61, an alarm controller 62, and an audible and visual alarm 63. The alarm controller 62 and the audible and visual alarm 63 are both installed at the bottom of the ceiling, and a monitoring probe 7 is installed at the bottom of the ceiling.
[0034] Furthermore, the transmitter 611 (infrared LED) and receiver 612 (photoelectric sensor) are used in pairs and installed on the inner walls of both sides of the fence 1 to form one or more infrared beam defense lines. Under normal circumstances, the receiver 612 continuously receives the infrared signal from the transmitter 611. When a person or object enters and blocks the beam, the signal of the receiver 612 is interrupted, and a trigger signal is immediately sent to the alarm controller 62. An adjustable angle bracket is used to ensure that the beam covers key areas horizontally or obliquely. The dustproof and waterproof design is suitable for outdoor environments. The alarm controller 62 is close to the sound and light alarm 63 for easy wiring and management. It receives the signal from the infrared beam detector 61 and has a built-in logic judgment module that can be set to delay the alarm (such as not triggering if there is a brief blockage). It is powered by the power supply of the transformer body 3. The infrared beam detector 61 is fixed with anti-tamper screws. The alarm mechanism 6 achieves multi-level protection through the coordinated design of infrared detection, sound and light deterrence and monitoring probe 7. It has real-time response, high reliability and easy maintenance, effectively improving the anti-theft and security capabilities of the power transformer.
[0035] The infrared beam detector 61 consists of a transmitter 611 and a receiver 612, which are respectively installed on the inner walls of both sides of the fence 1.
[0036] The infrared beam detector 61 consists of a transmitter 611 and a receiver 612 in pairs. The two must be strictly aligned to ensure stable transmission of the infrared beam. The transmitter 611 and the receiver 612 are respectively fixed on the inner walls on both sides of the fence 1 to form one or more parallel beam defense lines.
[0037] The anti-theft lock mechanism 5 includes a buckle 51 fixedly installed on one side of the inner wall of the protective box 2. A slot 52 is provided on one side of the buckle 51. Two mounting seats 53 are fixedly installed on the surface of the cabinet door 4. A pin rod 54 is slidably installed inside the two mounting seats 53. An elastic abutment 55 is provided on the surface of the pin rod 54 for inserting the pin rod 54 into the slot 52. An unlocking part 56 is provided on the surface of the cabinet door 4 for pushing the pin rod 54 to slide. One side of the buckle 51 and one end of the pin rod 54 are both set as bevels.
[0038] It should be noted that when the cabinet door 4 is closed, the inclined end of the latch 54 first contacts the inclined side of the buckle 51. Under the pressure of the door, the inclined structure generates a lateral force, which pushes the latch 54 to move and compresses the spring 552. When the latch 54 is aligned with the slot 52, the restoring force of the spring 552 pushes the latch 54 to quickly insert into the slot 52, completing the automatic locking (no manual operation required). When a special key is inserted into the lock hole 561, since the abutment rod 564 is rotatably installed in the groove 563, as the lock rod 562 rotates, the abutment rod 564 falls due to gravity. Rotating the abutment rod 564 again will push the follower block to move, thereby driving the movement of the latch 54 and separating the latch 54 from the buckle 51.
[0039] The elastic abutment 55 includes a follower block 551 fixedly installed on the surface of the pin 54. A spring 552 is provided between the surface of the follower block 551 and the mounting seat 53 away from the follower block 551. The spring 552 is movably sleeved on the surface of the pin 54.
[0040] It is worth noting that a follower block 551 is fixed on the surface of the pin 54, and a spring 552 is provided between the follower block 551 and the mounting base 53, which is sleeved on the pin 54 to form an elastic reset mechanism. When the cabinet door 4 is closed, the pin 54 is compressed and retracted, and the spring 552 stores energy. After aligning with the slot 52, the spring 552 releases energy to push the pin 54 to lock automatically. Locking can be completed without manual intervention, and the operation is simple.
[0041] An anti-detachment block 8 is fixedly installed on the surface of the follower block 551, and an anti-detachment groove 9 for the sliding of the anti-detachment block 8 is provided on the surface of the cabinet door 4.
[0042] Furthermore, the follower block 551 has an anti-detachment block 8 fixed on its surface, and an anti-detachment groove 9 is opened at the corresponding position of the cabinet door 4. This restricts the anti-detachment block 8 to slide only along the groove, ensuring that the pin rod 54 can only move horizontally in a straight line, preventing deflection or derailment, and forcing the pin rod 54 to move along a fixed trajectory, thereby improving the locking accuracy. The follower block 551 cannot be directly moved from the outside, thus enhancing its resistance to damage.
[0043] The unlocking component 56 includes a lock hole 561 opened in the cabinet door 4, a lock rod 562 slidably installed inside the lock hole 561, a groove 563 opened inside the lock rod 562, and an abutment rod 564 for pushing the follower block 551 rotatably installed inside the groove 563.
[0044] It should be noted that when the key is inserted into the lock hole 561 and the lock bar 562 is rotated, the abutment rod 564 in the groove 563 inside the lock bar 562 rotates accordingly. Since the abutment rod 564 is rotatably installed in the groove 563, as the lock bar 562 rotates, the abutment rod 564 falls due to gravity. When the abutment rod 564 is rotated again, the vertical abutment rod 564 will push the follower block to move, thereby driving the pin rod 54 to move, so that the pin rod 54 separates from the buckle 51.
[0045] A magnetic block 10 is embedded in the side of the follower block 551 near the lock hole 561, and the abutment rod 564 is a metal rod.
[0046] The magnetic block 10 is positioned on the side of the follower block 551 near the lock hole 561. When the metal abutment rod 564 rotates and falls, the magnetic block 10 will attract the abutment rod 564 closer, making it easier for the abutment rod 564 to push the follower block 551.
[0047] The enclosure 1 of this device serves as the first line of defense, preventing unauthorized personnel or animals from easily approaching the transformer. It employs a spring-driven pin 54 and latch 51 structure, automatically locking when the cabinet door 4 is closed. The transmitter 611 and receiver 612 of the infrared beam detector 61 are installed on both sides of the enclosure 1, forming one or more invisible beam defense lines. When a person or object enters and blocks the infrared beam, an alarm signal is triggered. The alarm controller 62 receives the signal from the infrared detector and determines whether an alarm has been triggered. It can link with the monitoring probe 7 to record video and activate the audible and visual alarm 63. When the cabinet door 4 is closed, the pin 54 automatically inserts into the latch 51's slot 52 under the action of the spring 552, completing the locking and achieving self-locking. No manual locking is required; a special key must be inserted, and turning the key causes the abutment rod 564 to push the follower block 551, compressing the spring 552 and pulling out the pin 54 before the door can be opened.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
