One end of the main support rod is fixedly connected to the front and sides of the transformer, and the other end of the main support rod is provided with a secondary support rod. One end of the secondary support rod is movably connected to the other end of the main support rod.
[0007] Preferably, the other end of the secondary support rod is provided with a baffle, the back of the baffle is fixedly connected to the other end of the secondary support rod, the front of the baffle is provided with several rollers, the two sides of the rollers are provided with roller shafts, one end of two roller shafts passes through the roller and extends into the interior, and several heat dissipation holes are opened on the surface of the roller.

Bolts are provided on both sides of the bottom of the bracket, and a heat-conducting plate is provided at the bottom of the bracket, with the bottom of the heat-conducting plate in contact with the top of the transformer.

[0011] Preferably, a cooling fan is provided on the front of the heat dissipation tank.
[0012] Preferably, the heat dissipation pipe structure is an elastic buffer device, and the pipe body is made of elastic material.
[0013] Compared with the prior art, the technical solution of the present invention has the following advantages:
[0014] (1) Highly efficient integration of heat dissipation and protection functions, improving equipment reliability and applicability. This liquid-cooled containerized protective dry-type transformer for power generation innovatively integrates the heat dissipation system with the anti-collision structure, solving the problem that traditional transformers cannot balance heat dissipation and protection. The heat dissipation pipe structure adopts an elastic tube design, with a main support frame, springs, and a secondary support frame inside. During normal operation, it serves as a liquid cooling circulation channel. When encountering external impact, the elastic tube deformation combined with the spring buffer mechanism can effectively absorb the impact energy and reduce damage to the transformer body. In addition, the heat dissipation pipes are distributed on the front and sides of the transformer, ensuring uniform heat dissipation while forming an all-round protective barrier, which is especially suitable for container environments with limited space. The liquid cooling system consists of a heat dissipation tank, a water pump, and a cooling fan. When the thermal sensing structure detects an abnormal temperature, it automatically starts to ensure efficient heat dissipation. This integrated design not only reduces the installation requirements of additional protective devices but also improves the stability and service life of the equipment, making it suitable for high-load power scenarios.
[0015] (2) Intelligent temperature control and rodent-proof design enhance safety and environmental adaptability. This transformer effectively solves the shortcomings of traditional equipment in temperature management and biological protection through intelligent temperature control and rodent-proof structure. The heat-sensing structure consists of a heat-conducting plate, an expansion airbag, and a sensing electrode. When the transformer temperature rises, the heat is conducted to the expansion airbag, causing it to expand and push the contact head and sensing head to close, triggering the alarm and starting the liquid cooling system to achieve automated temperature control and avoid the risk of overheating. At the same time, multiple layers of rollers are set on the baffle. Their rotation characteristics can prevent rodents from climbing, while the heat dissipation holes on the surface of the rollers do not affect ventilation and heat dissipation, thus taking into account both rodent-proof and auxiliary heat dissipation functions. This design is particularly suitable for environments with frequent rodent infestations, such as field substations and industrial plants, avoiding the problem of traditional rodent-proof nets hindering heat dissipation. The combination of intelligent temperature control and physical rodent prevention significantly improves the safety and environmental adaptability of the equipment and reduces failures caused by biological attacks or temperature runaway.
[0016] (3) Modular elastic support structure optimizes seismic performance and reduces maintenance costs. The elastic design of the transformer's support structure and heat dissipation pipes significantly improves seismic resistance and maintainability. The support structure adopts a movable connection between the main support rod and the auxiliary support rod, combined with baffles to form a buffer layer. When subjected to impact, the impact force is dispersed through deformation, reducing the impact on the transformer body. The elastic material and internal springs of the heat dissipation pipe structure further enhance seismic resistance, making it suitable for areas prone to transportation vibrations or earthquakes. In addition, the modular design means that when there is local damage such as baffle deformation or support rod breakage, only the corresponding parts need to be replaced, without the need for overall disassembly, which greatly reduces maintenance costs and time. The independent design of the cooling water tank and water pump also facilitates coolant replacement and system maintenance. Overall, this solution improves the maintainability and economy of the equipment while ensuring protective performance through optimized structural design and material selection, making it suitable for power application scenarios with high requirements for reliability and cost control.

[0035] An expansion airbag 905 is provided on the top of the heat-conducting plate 907, and a contact head 909 is provided on the top of the expansion airbag 905.

[0036] A cooling water tank 4 is provided on the back of the transformer 1. A water inlet is provided on one side of the top of the cooling water tank 4, and the water inlet is fixedly connected to the heat dissipation pipe structure 8. A water outlet is provided on the other side of the top of the cooling water tank 4. A water pump 6 is provided on one side of the cooling water tank 4. One side of the water pump 6 is fixedly connected to the water outlet. The top of the water pump 6 is fixedly connected to the heat dissipation pipe structure 8. The top of the water pump 6 is connected to the other end of the power line 906 in the circuit.
[0037] A cooling fan 5 is installed on the front of the heat dissipation tank 4.
[0038] The heat pipe structure 8 is an elastic buffer device, and the pipe body 801 is made of elastic material.
[0039] The working principle and usage process of this invention: This invention combines a liquid cooling system with an anti-impact shock absorption device. Under normal operating conditions, the liquid cooling system does not work. When the temperature exceeds the normal range, the heat sensing structure 9 located on top of the transformer 1 starts to work. The specific process is as follows: When the heat of the transformer 1 is transferred to the expansion bladder 905 through the heat conduction plate 907, it expands. During the expansion process, the contact head 909 on the top of the expansion bladder 905 moves upward continuously and contacts the sensing head 908, triggering the sensing electrode 901. The switch then powers the water pump 6 and the cooling fan 5 through the power line 906, enabling the liquid cooling system to start working. At the same time, the alarms 902 on both sides of the sensing electrode 901 start to alarm, notifying the staff that the transformer 1 temperature has risen and that they need to pay close attention to prevent malfunctions. During the operation of the liquid cooling system, the cooling water tank 4 pumps coolant into the heat dissipation pipe structure 8 through the water pump 6. The coolant flows in the pipe body 801, absorbs the heat generated by the transformer 1, and then flows back to the cooling water tank 4 for cooling. The cooling fan 5 accelerates the heat dissipation of the cooling water tank 4, forming a highly efficient liquid cooling circulation system. The tube body 801 also contains several anti-collision devices consisting of a main support frame 802, a spring 803, and a secondary support frame 804. Because the tube body 801 is made of elastic material, it can deform upon impact. The main support frame 802 and secondary support frame 804 move closer together, stretching the spring 803. This process dissipates the impact potential energy and mitigates damage to the transformer 1. Several baffles 2 are installed outside the transformer 1. The baffle 2 and the transformer 1 body are directly connected through the support structure 7. When an impact occurs, the baffle 2 makes contact with the impact immediately, causing the support structure 7 to undergo compression deformation. The hydraulic characteristics generate damping to further reduce the impact force. The baffle 2 and the heat dissipation pipe structure 7 work together to reduce the impact. The baffle 2 is also equipped with multiple layers of rollers 3 for rodent prevention. When rodents attempt to climb the outer baffle 2 of the transformer 1, they will be unable to climb due to the rotation of the rollers 3. The multiple layers of rollers 3 ensure safety. At the same time, the surface of the rollers 3 is provided with several heat dissipation holes to further help dissipate heat.
