Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and in particular to a distribution transformer terminal device with safety protection. Background Technology

[0002] With the advancement of smart grid construction, distribution transformer terminals, as key nodes for power distribution network monitoring and control, face increasingly prominent security risks such as physical environmental interference, electrical faults, and network attacks. It is necessary to strengthen security protection capabilities to ensure the stable and reliable operation of the power distribution system.

[0003] The existing main equipment consists of conventional distribution transformer terminals and distribution automation terminals. Conventional distribution transformer terminals are composed of core control, data acquisition, communication modules and basic protection units. They collect transformer operating parameters, process them and upload them to the main station and receive instructions. The basic protection unit provides simple overcurrent and overvoltage protection. The communication interface module and central processing unit collect and process line information and interact with the main station and other terminals to realize line monitoring and fault isolation. The protection is designed around electrical insulation and basic communication safety.

[0004] Typically, distribution transformer terminal equipment with safety protection features employs a sealed internal design to enhance protection. While this structure effectively blocks external environmental interference, it also leads to poor ventilation inside the equipment. When heat accumulates during operation and the temperature becomes too high, it can easily cause a decrease in equipment operating efficiency and even affect its stability. Furthermore, the installation structure of this type of equipment is often only compatible with fixed sizes, making it difficult to achieve compatible installation with different specifications of supporting equipment. Additional adjustments or replacements of components are required, significantly reducing the convenience of installation and maintenance. Therefore, a distribution transformer terminal equipment with safety protection is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a distribution transformer terminal device with safety protection, which aims to improve the problems of the inability to ventilate and cool down and to install equipment of different sizes in the prior art.

As a further description of the above technical solution: The bottom top inner side is slidably connected to multiple evenly distributed slide rails, the inner side of the slide rails is slidably connected to a movable rod two, the outer periphery of the movable rod two is fixedly connected to a fixed block, the top of the fixed block is fixedly connected to a clamping plate, and the inner side of the clamping plate is threadedly connected to a fixed threaded rod. As a further description of the above technical solution: The base is fixedly connected to a cabinet body at its bottom. Multiple evenly distributed hinges are fixedly connected to the rear of the cabinet body. A cabinet door is fixedly connected to the front of each hinge. A handle is fixedly connected to the rear of the cabinet door. As a further description of the above technical solution: The cabinet body has ventilation holes inside, and the cabinet door has ventilation holes inside; As a further description of the above technical solution: The top of each base is provided with a sliding groove, and the top of each base is provided with a fixing groove; As a further description of the above technical solution: The roller is slidably connected to the inside of the groove, and the fixed threaded rod is slidably connected to the inside of the fixed groove; As a further description of the above technical solution: The base abuts against the front of the cabinet door; As a further description of the above technical solution: A nut is fixedly connected to the top of the threaded rod.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the cooling fan is connected to and rotates synchronously with the rotating block, which can quickly expel hot air from the cabinet through the vents, effectively preventing excessive temperature from affecting equipment operation. The rotating block is securely connected to the connecting rod, which in turn is connected to the movable rod. The rollers on the movable rod can slide flexibly up and down along the slide rail, driving the entire heat dissipation structure to adjust its height to adapt to different heat dissipation needs. This allows the cooling fan to operate efficiently in the appropriate position, ensuring stable internal temperature of the cabinet and thus solving the problem of insufficient ventilation for cooling.

[0008] 2. In this utility model, the base is provided with a sliding groove and a fixing groove. When the roller slides in the sliding groove, it can drive the clamping plate above to move laterally so as to adjust the distance between the two clamping plates according to the equipment specifications.

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.

[0012] Reference Figures 1-2This utility model provides an embodiment of a distribution transformer terminal device with safety protection, including a base 11. A slide rail 3 is fixedly connected to the top of the base 11. Rollers 13 are slidably connected to both the left and right sides inside the slide rail 3. A movable rod 5 is rotatably connected to one side of the rollers 13. A connecting rod 6 is fixedly connected to the outer periphery of the movable rod 5. A rotating block 7 is rotatably connected to the outer periphery of the connecting rod 6. Multiple evenly distributed heat dissipation blades 8 are fixedly connected to the outer periphery of the rotating block 7. The slide rail 3 fixedly connected to the top of the base 11 provides the installation and movement foundation for the entire heat dissipation structure. The rollers 13 slidably connected to the left and right sides inside the slide rail 3 can move up and down along the slide rail 3, thereby driving the movable rod 5 rotatably connected to the opposite side to adjust its height synchronously. The connecting rod 6 fixed to the outer periphery of the movable rod 5 transmits power to the rotating block 7 rotatably connected to its outer periphery, allowing the rotating block 7 to rotate freely. The multiple evenly distributed heat dissipation blades 8 fixed to the outer periphery of the rotating block 7 rotate together with the rotating block 7, forming a complete heat dissipation structure. The thermodynamic component enables the linkage of heat dissipation and position adjustment functions. The bottom of the base 11 is fixedly connected to the cabinet 1. Multiple evenly distributed hinges 10 are fixedly connected to the rear of the cabinet 1. The front of the hinges 10 is fixedly connected to the cabinet door 2. The rear of the cabinet door 2 is fixedly connected to the handle 20. The bottom of the base 11 is fixedly connected to the cabinet 1, forming the basic load-bearing structure of the equipment. The rear of the cabinet 1 is connected to the cabinet door 2 through multiple evenly distributed hinges 10. The hinges 10 provide a stable mounting point for the cabinet door 2 and give it the ability to rotate around the cabinet 1, allowing the cabinet door 2 to open and close flexibly. The handle 20 fixed to the rear of the cabinet door 2 provides a convenient force point for the operator to open and close the cabinet door 2. Through this series of connections, the cabinet 1 and the cabinet door 2 together constitute the protective shell of the equipment, realizing the closed protection of the internal components. Ventilation holes 9 are opened inside the cabinet 1 and the cabinet door 2. The base 11 abuts against the front of the cabinet door 2.

[0013] Reference Figure 1 and Figure 3Multiple evenly distributed slide rails 3 are slidably connected to the inner side of the top of the base 11. A movable rod 14 is slidably connected to the inner side of the slide rails 3. A fixed block 15 is fixedly connected to the outer periphery of the movable rod 14. A clamping plate 16 is fixedly connected to the top of the fixed block 15. A fixed threaded rod 17 is threadedly connected to the inner side of the clamping plate 16. The multiple evenly distributed slide rails 3 slidably connected to the inner side of the top of the base 11 provide a stable sliding track for the movable rod 14. The movable rod 14 can move flexibly along the slide rails 3, and the fixed block 15 fixedly connected to its outer periphery moves along with it, thereby driving the clamping plate 16 fixedly connected to the top of the fixed block 15 to adjust its position synchronously. The fixed threaded rod 17 threadedly connected to the inner side of the clamping plate 16 can move up and down through the threaded engagement, forming a complete adjustment and fixing linkage structure to ensure clamping operation. To ensure stability and flexibility, the top of the base 11 is provided with a sliding groove 12 and a fixing groove 19. The roller 13 is slidably connected to the inside of the sliding groove 12, and the fixed threaded rod 17 is slidably connected to the inside of the fixing groove 19. The roller 13 can slide stably along the trajectory of the sliding groove 12, thereby driving the associated components to achieve position adjustment. The fixed threaded rod 17 is slidably connected to the inside of the fixing groove 19, which not only provides a moving guide for the fixed threaded rod 17, but also forms a stable locking structure through the limiting effect of the fixing groove 19 when it rotates downward and presses against the ground. The two, through the cooperation of the sliding groove 12 and the fixing groove 19, jointly ensure the accuracy and reliability of the equipment adjustment and fixing process. The top of the fixed threaded rod 17 is fixedly connected with a nut 18.

[0014] Working principle: When the heat dissipation blades 8 rotate synchronously with the rotating block 7, they will form a continuous airflow circulation, which will efficiently guide the heat generated inside the cabinet 1 due to the operation of the equipment to the cabinet door 2 and the ventilation holes 9 on the cabinet 1, and quickly exhaust it to the outside of the cabinet 1 through the ventilation holes 9, thereby effectively maintaining a suitable temperature environment inside the cabinet 1. The rotating block 7 is firmly connected to the connecting rod 6, which in turn is tightly connected to the movable rod 5. This interlocking connection structure allows the movable rod 5 to drive the entire heat dissipation assembly to move synchronously. The pulley 4 on the movable rod 5 can roll stably along the track of the slide rail 3. The height of the heat dissipation blades 8 can be flexibly adjusted by sliding up and down to meet the heat dissipation needs of different areas inside the cabinet 1. When it is necessary to fix the equipment, after the equipment is placed stably on the base 11, the roller 13 connected to the movable rod 14 can slide along the slide groove 12. The movable rod 14 is rigidly connected to the clamping plate 16 through the fixing block 15. Therefore, the sliding of the roller 13 will drive the clamping plates 16 on both sides to move laterally synchronously until they are tightly fitted to both sides of the equipment to achieve a stable clamping. At this time, the fixing threaded rod 17 on the inner side of the clamping plate 16 is rotated so that it moves downward along the thread and is embedded in the corresponding fixing groove 19. Through the limiting effect of the fixing groove 19 and the fastening force of the threaded rod, the position of the clamping plate 16 is firmly locked, and finally the reliable fixing of equipment of different specifications is completed.
