However, existing transformer rectifiers have some shortcomings, such as:

[0003] The low-loss photovoltaic power generation transformer described in application number CN201720486911.9 only focuses on improving the performance of the transformer itself and lacks comprehensive safety protection functions during the operation of the transformer, such as real-time temperature monitoring, active heat dissipation, and emergency fire extinguishing. It is only applicable to photovoltaic power generation scenarios, with a narrow application field, and it is difficult to meet the needs of other different industry scenarios that require transformer rectifiers. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection structure for a transformer rectifier, in order to solve the problem that the existing patents on the market mentioned in the background only focus on improving the performance of the transformer itself and lack comprehensive safety protection functions during the operation of the transformer, such as the lack of real-time temperature monitoring, active heat dissipation, emergency fire extinguishing and other designs. They are only applicable to photovoltaic power generation scenarios, with a narrow application field, and cannot meet the needs of other different industry scenarios that require transformer rectifiers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection structure for a transformer rectifier, comprising a transformer body, a guide pipe, a protective cover, a rotating nozzle, and a battery pack;

[0006] An active protection structure is installed below the transformer body. The active protection structure includes an oil pan, a centrifugal pump, a motor, a guide pipe, and a rotating nozzle. The oil pan is fixedly connected to the bottom of the transformer body. The centrifugal pump and the motor are fixedly connected to the inside of the oil pan. The guide pipe is connected to the centrifugal pump, and the rotating nozzle is installed at the top of the guide pipe.

[0007] As a preferred technical solution of this utility model, a panoramic camera is fixedly connected to the upper surface of the transformer body, and the panoramic camera is equipped with a temperature sensing function. The panoramic camera has a built-in microprocessor and is powered by a battery pack.

[0008] Using the above technical solution, a panoramic camera fixed to the upper surface of the transformer body is equipped with a temperature sensing function. Its built-in microprocessor can process temperature data in real time. Combined with a battery pack power supply design, it can continuously monitor the temperature anomalies of the environment around the transformer and the operating status of the equipment during power outages. By combining 360° panoramic monitoring with temperature sensing early warning, potential safety hazards such as local overheating can be detected in advance, achieving proactive protection and improving the safety and reliability of equipment operation.

[0009] As a preferred technical solution of this utility model, the bottom of the transformer body is fixed with an oil pan by bolts, and the oil pan has an overall U-shaped structure;

[0010] The above technical solution uses a U-shaped oil pan that is fixed to the bottom of the transformer body with bolts. The bolt connection method not only ensures the firm fixation of the oil pan to the transformer body, but also facilitates disassembly and maintenance. Impurities in the oil pan can be cleaned regularly, ensuring the long-term stable operation of the active protection structure.

[0011] As a preferred technical solution of this utility model, a centrifugal pump is fixedly connected to the inner side of the oil pan, and the oil inlet of the centrifugal pump is a grid structure set on the top and side of the centrifugal pump. A motor is fixedly connected to the left side of the centrifugal pump, and the motor is waterproof.

[0012] Using the above technical solution, the centrifugal pump fixed inside the oil pan has oil inlet grilles on its top and sides that can filter particulate impurities in the oil, preventing the pump body from becoming clogged or worn; the waterproof motor on the left can work safely in humid or oily environments, avoiding failure of the active cooling system due to motor failure, ensuring that the centrifugal pump continuously delivers oil to the guide pipe, and maintaining the heat dissipation function of the protective structure.

[0013] As a preferred technical solution of this utility model, the oil pan side is vertically fixed with a guide pipe, the guide pipe is an L-shaped structure, and a protective cover is fitted on the outside of the guide pipe. The protective cover is a rectangular tubular structure and is embedded and fixed on the side of the transformer body.

[0014] Using the above technical solution, the L-shaped guide pipe vertically fixed on the side of the oil pan can change the direction of oil flow to adapt to the structure of the transformer body, so that the oil can be transported upward to the rotating nozzle; the rectangular tubular protective cover on the outside is embedded and fixed on the side of the transformer body, which can protect the guide pipe from external collision damage without affecting the flow of oil, ensuring the smoothness of the heat dissipation oil circuit and the protection of the structure.

[0015] As a preferred technical solution of this utility model, the guide pipe is connected to the centrifugal pump, and the top of the guide pipe has an internal thread structure. A fixing ring is threadedly connected to the top of the guide pipe. The fixing ring is fitted on the outside of the rotating nozzle, and three nozzles are fixedly connected to the side of the rotating nozzle. The nozzles have a conical structure and are distributed in an equilateral triangle.

[0016] Using the above technical solution, the internal thread structure at the top of the guide pipe is threadedly connected to the fixing ring, which facilitates the installation and disassembly of the rotating nozzle; the three cone-shaped nozzles on the side of the rotating nozzle, which are distributed in an equilateral triangle, can form an atomized spray when the oil is sprayed out, reducing the ambient temperature. Adding flame retardants to the transformer oil can achieve active fire extinguishing protection in emergency situations, greatly reducing property damage and danger.

[0017] As a preferred technical solution of this utility model, a limiting groove is provided above the oil pan, and a battery pack is slidably connected inside the oil pan. The battery pack uses a lithium battery, and a handle is fixedly connected to the right side of the battery pack.

One end of the insert rod is fixedly connected to a spring, and the other end of the spring is fixedly connected to the handle. The insert rod is engaged in the limiting groove.

[0018] By adopting the above technical solution, the sliding connection structure between the limiting groove above the oil pan and the battery pack, together with the limiting component consisting of a handle, a plug rod, and a spring, allows the lithium battery pack to be easily removed for charging or replacement. The spring-returned plug rod is engaged in the limiting groove, which can prevent the battery pack from shaking due to vibration during equipment operation, ensuring stable power supply. At the same time, the high energy density of the lithium battery ensures the continuous operation of devices such as panoramic cameras.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. A panoramic camera is fixedly connected to the upper surface of the transformer body. The panoramic camera is equipped with a temperature sensing function, has a built-in microprocessor, and is powered by a battery pack. This design enables 360° monitoring without blind spots through the panoramic camera, real-time temperature sensing of temperature changes, and rapid data processing by the microprocessor. It triggers an alarm when an anomaly is detected, and can continue to work even in the event of a power outage thanks to the battery pack. This enhances the ability to monitor the ambient temperature around the transformer and the operating status of the equipment, achieving proactive protection and improving the safety and reliability of equipment operation.

[0021] 2. The U-shaped oil pan is fixed to the bottom of the transformer body by bolts. The bolt fixing method not only ensures a firm connection between the oil pan and the transformer body, but also facilitates disassembly and maintenance. Impurities in the oil pan can be cleaned regularly, ensuring the long-term stable operation of the active protection structure.

[0022] 3. A centrifugal pump is fixedly connected to the inner side of the oil pan. Its oil inlet is a grid structure set on the top and side, and a waterproof motor is fixedly connected to the left side. The grid oil inlet can filter particulate impurities in the oil, prevent the centrifugal pump from clogging or wearing, and extend its service life. The waterproof motor can operate safely in humid or oily environments, avoiding failure of the active cooling system due to motor failure, ensuring that the centrifugal pump continuously delivers oil to the guide pipe, and maintaining the heat dissipation function of the protective structure.

[0023] 4. An L-shaped guide pipe is vertically fixed to the side of the oil pan, and a rectangular tubular protective cover is fitted and fixed to the side of the transformer body. The top of the guide pipe has an internal thread structure, and a rotating nozzle is fitted by a threaded connection and fixing ring. Three conical nozzles distributed in an equilateral triangle are fixedly connected to the side of the rotating nozzle. A limiting groove is opened above the oil pan, and a battery pack with lithium battery and limited by a handle, plug rod and spring is slidably connected inside. The L-shaped guide pipe can change the direction of oil flow, so that the oil is delivered upward to the rotating nozzle. The protective cover protects the guide pipe from external collision damage. The design of the rotating nozzle and conical nozzles makes the oil spray into an atomized spray. If a flame retardant is added to the transformer oil, active fire extinguishing can be achieved in an emergency, reducing property damage and danger. The battery pack ensures the power supply of the equipment, and its sliding connection and limiting structure make it easy to remove for charging or replacement, ensuring stable power supply.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Please see Figure 1 - Figure 6 The present invention provides a safety protection structure for a transformer rectifier, comprising a transformer body 1, a guide pipe 2, a protective cover 3, a rotating nozzle 4, an oil pan 5, a centrifugal pump 6, a motor 7, a nozzle 8, a fixing ring 9, a spring 10, a plug rod 11, a limiting groove 12, a handle 13, a panoramic camera 14, and a battery pack 15.

[0033] The active protection structure installed below the transformer body 1 consists of an oil pan 5, a centrifugal pump 6, a motor 7, a guide pipe 2, and a rotating nozzle 4. The oil pan 5 is fixed to the bottom of the transformer body 1. The centrifugal pump 6 and the motor 7 are installed inside the oil pan 5. The guide pipe 2 is connected to the centrifugal pump 6 and is equipped with a rotating nozzle 4 at its top. This structure drives the centrifugal pump 6 through the motor 7 to transport the transformer oil in the oil pan 5 to the rotating nozzle 4 through the guide pipe 2. The oil is then atomized and sprayed out by the nozzle to achieve emergency active heat dissipation, forming a dynamic heat dissipation circulation system. Compared with the traditional passive heat dissipation method, this can effectively reduce the operating temperature of the transformer body 1 and improve the equipment load capacity and service life.

[0034] The panoramic camera 14 fixed on the upper surface of the transformer body 1 integrates temperature sensing function, has a built-in microprocessor and is powered by battery pack 15. It can collect 360° environmental images and temperature data around the transformer in real time. The microprocessor analyzes the temperature field distribution through preset algorithm. When the local temperature exceeds the threshold, it automatically triggers the alarm mechanism and links the active protection structure to enhance heat dissipation. At the same time, it supports the storage and remote transmission of monitoring data, providing data support for equipment status assessment and building an intelligent safety protection system that integrates monitoring, early warning and control.

[0035] The oil pan 5 adopts a U-shaped structure and is fixed to the bottom of the transformer body 1 with bolts. This design not only utilizes the U-shaped groove to efficiently collect leaked oil, but also enables disassembly and maintenance through bolt connection. This facilitates regular cleaning of metal debris, sludge and other impurities deposited in the oil pan 5. Combined with the grid oil inlet holes on the top and side of the centrifugal pump 6, a multi-stage filtration mechanism can be formed to prevent impurities from entering the pump body and causing mechanical damage, and to ensure the long-term reliable operation of the active heat dissipation system.

[0036] The guide pipe 2 has an L-shaped structure and is fitted with a rectangular tubular protective cover 3. The protective cover 3 is embedded and fixed to the side of the transformer body 1. This optimizes the oil delivery path by turning the pipe, allowing the oil to be sprayed vertically upwards to the top heat dissipation surface of the transformer body 1. The protective cover 3 also provides physical protection for the guide pipe 2, preventing damage to the pipe due to external impact or foreign object intrusion. The threaded connection between the internal thread at the top of the guide pipe 2 and the fixed ring 9 enables quick installation and removal of the rotating nozzle 4. The three equilateral triangularly distributed conical nozzles 8 atomize the oil, and the atomization coverage area is significantly larger than that of traditional direct injection. Combined with the sliding limit installation structure of the lithium battery pack 15, the hot-swappable replacement of the power supply module is achieved through the linkage of the handle 13, the plug rod 11 and the spring 10, ensuring the continuous operation of the monitoring and heat dissipation protection system.

[0037] Working principle: When using a safety protection structure for a transformer rectifier, the panoramic camera 14 monitors the temperature in real time and triggers an alarm when there is an abnormality. The centrifugal pump 6 driven by the motor 7 draws transformer oil from the U-shaped oil pan 5 and delivers it to the top rotating nozzle 4 through the L-shaped guide pipe 2. The oil is then atomized and sprayed out through three equilateral triangularly distributed conical nozzles 8 to achieve active fire extinguishing. During operation, the oil inlet grille of the centrifugal pump 6 filters impurities, and the outer protective cover 3 of the guide pipe 2 prevents collisions.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
