Description

Technical Field

[0001] The utility model relates to the technical field of electric power safety, in particular to a safety mechanism of an electric power system of a power plant. Background Art

[0002] The power system of a power plant is a comprehensive system that includes multiple parts such as power generation, transmission, distribution, and control and protection. The power generation system converts various forms of energy into electricity through generators and increases the voltage of electricity through transformers for long-distance transmission. The transmission system uses high-voltage transmission lines and substations to transmit electricity to various load centers, while the distribution system further reduces the voltage of electricity and delivers it to end users through distribution lines. During operation, the power system of a power plant requires the use of safety mechanisms to provide protection for electronic components and personnel. These safety mechanisms include electrical cabinets and relays that can monitor the status of the power system in real time, detect abnormal conditions such as overload, short circuit, or equipment failure, and take prompt measures to protect the safety of equipment and personnel.

[0003] Traditional power safety mechanisms typically consist of electrical cabinets and relays. The electrical cabinets centrally manage and control various devices in the power system, providing necessary protection and control functions. Relays, on the other hand, monitor the power system status in real time and quickly cut off power to protect the system and equipment when abnormal conditions such as overload, short circuit, or equipment failure are detected.

[0004] However, traditional power safety mechanisms often use alarms to warn of abnormal conditions in the power system, and the alarms are usually installed above the electrical cabinet with bolts. When the alarm needs to be maintained or replaced, personnel need to climb to a high place to disassemble and install the alarm. The process is cumbersome and time-consuming, and there are potential risks. Therefore, a safety mechanism for the power system of a power plant is proposed to solve the above problems.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a safety mechanism of the power system of a power plant, including an electric cabinet 1, the electric cabinet 1 is used to provide centralized management and protection for the power system, a support plate 2 is fixedly connected to the inside of the electric cabinet 1, a mounting base 3 is provided on one side of the electric cabinet 1, and an alarm 4 is fixedly connected to the outer wall of the mounting base 3. The alarm 4 is a centralized alarm 4 commonly used on power equipment in the prior art, which can centrally monitor the tripping or power-off conditions of multiple devices and give alarm prompts through sound and light, etc., a rotating plate 5 is rotatably connected to one side of the support plate 2, and a transmission rod 6 in a matrix column shape is rotatably connected to one side of the rotating plate 5, and the transmission rod 6 is used to drive the rotating plate 5 to rotate, and each transmission rod 6 is rotatably connected to a connecting column 7 at one end, and each connecting column 7 is fixedly connected to a slide 8 at one end, and the function of the slide 8 is to provide a support basis for connection and movement, where one of the slides 8 is One side is fixedly connected to a support plate 9, and the other side of the skateboard 8 is fixedly connected to a connecting plate 10. One side of the support plate 9 is fixedly connected to an electric push rod 11, and the connecting plate 10 is fixedly connected to the output end of the electric push rod 11. The support plate 9 is connected to the connecting plate 10 through the electric push rod 11. The electric push rod 11 is used to provide power to drive the connecting plate 10 to move, thereby realizing the adjustment of the skateboard 8. A mounting assembly is provided on one side of the skateboard 8, and the mounting assembly is used to fix the mounting seat 3. The mounting assembly includes a support block 12 and a clamping block 13. The clamping block 13 is fixedly connected to one side of the skateboard 8, and the clamping block 13 is fixedly connected to one side of the support block 12. The support block 12 and the clamping block 13 are both slidably connected to the inside of the mounting seat 3, and the movement of the skateboard 8 is transmitted to the support block 12 and the clamping block 13, so that it can slide inside the mounting seat 3, thereby firmly fixing the mounting seat 3.

[0034] Specifically, when the alarm 4 in the power system needs to be disassembled and assembled, the mounting seat 3 inside the alarm 4 is first inserted into the support block 12 and the card block 13. At this time, the output end of the electric push rod 11 drives the connecting plate 10 to move, and the movement of the connecting plate 10 further pushes the slide plate 8 connected on one side to displace. The movement of the slide plate 8 is further transmitted to the connecting column 7, causing the connecting column 7 to displace. The movement of the connecting column 7 then causes the transmission rod 6 connected to the outer wall to rotate. The rotation of the transmission rod 6 will drive the rotating plate 5 connected to one end to rotate synchronously. The rotation of the rotating plate 5 further drives multiple transmission rods 6 on one side to move in a coordinated manner. These transmission rods 6 push the slide plate 8 to the surroundings. After being subjected to force, each slide plate 8 will also push the support block 12 connected to it to slide inside the support disk 2, so that the support block 12 drives the card block 13 on one side to expand inside the mounting seat 3. At this time, the card block 13 is expanded and locked inside the mounting seat 3, so that the alarm 4 can be firmly fixed, so that the alarm 4 can be quickly disassembled and assembled, ensuring timely maintenance and normal operation of the alarm 4 in the power system.

[0035] Reference Figure 1 、 Figure 4 and Figure 5 , a wire rack 16 is fixedly connected to the inside of the electrical cabinet 1, and the wire rack 16 is used to organize and support cables and other electrical components. A connecting frame 17 is fixedly connected to the inside of the support frame 14, and a turntable 18 is rotatably connected to the inside of the connecting frame 17. The outer wall of the turntable 18 is fixedly connected to a handle 19, and the handle 19 is used to manually operate the turntable 18 so that the rotation of the turntable 18 can drive other components to move. A fixed column 21 is fixedly connected to the inside of the connecting frame 17, and a slide groove 20 is provided inside the turntable 18. The fixed column 21 is slidably connected to the inside of the slide groove 20 to ensure stable rotation and position control of the turntable 18. A connecting rod 22 is rotatably connected to one side of the connecting frame 17, and a blade 23 is rotatably connected to one side of the connecting rod 22. The blade 23 is used to control the opening and closing of the air outlet to achieve the effect of controlling the ventilation rate and dust prevention. A support ring 24 is fixedly connected to the inside of the connecting frame 17, and the blade 23 is rotatably connected to one end of the support ring 24. The support ring 24 is used to provide stable rotation support for the blade 23.

[0036] Specifically, when it is necessary to dissipate heat inside the electrical cabinet 1, the heat dissipation process can be started by toggling the handle 19. The toggling of the handle 19 will drive the internal turntable 18 to rotate in the connecting frame 17. The rotation of the turntable 18 will cause the connecting rod 22 on one side to move. The movement of the connecting rod 22 will then drive the blade 23 connected to one side of it to move accordingly, so that the blade 23 opens and closes under the support of the support ring 24. By adjusting the opening and closing amplitude of the blade 23, the ventilation rate can be controlled according to demand.

[0037] Reference Figure 1 、 Figure 4 and Figure 5 A support frame 14 is fixedly connected to one side of the electrical cabinet 1. A fan 15 is provided inside the support frame 14, which is responsible for effectively dissipating heat inside the electrical cabinet 1 to maintain the normal operating temperature of the equipment. Ventilation holes 25 are opened inside the blades 23. The ventilation holes 25 are used to ensure that air can keep circulating when the air outlet is closed.

[0038] Specifically, the opening and closing movement of the blades 23 causes the air vents in the support frame 14 to open, and the opening of the air vents causes the fan 15 inside the support frame 14 to start to effectively dissipate heat from the inside of the electrical cabinet 1. The fan 15 takes away the heat from the inside of the electrical cabinet 1 through the airflow, thereby reducing the operating temperature of the equipment and ensuring the stability and reliability of the power system. In addition, when encountering windy and rainy weather, the handle 19 can be operated again to cause the movement of the turntable 18, the connecting rod 22 and the blades 23 to close the air vents. The closing of the blades 23 can effectively prevent external rainwater or pollutants from entering the interior of the electrical cabinet 1, and through the ventilation holes 25 opened in the blades 23, the air vents can still maintain stable ventilation when closed, and the aperture of the ventilation holes 25 is small, which can effectively block a large amount of external rainwater and dust, thereby achieving effective protection for the interior of the electrical cabinet 1.

[0039] Working principle: When the alarm 4 in the power system needs to be disassembled and assembled, first insert the mounting seat 3 connected inside the alarm 4 outside the support block 12 and the card block 13. At this time, the output end of the electric push rod 11 drives the connecting plate 10 to move, and the connecting plate 10 is subjected to force to drive the slide plate 8 connected on one side to move, and the slide plate 8 is subjected to force to drive the connecting column 7 connected on one side to move, and the connecting column 7 is subjected to force to drive the transmission rod 6 connected to the outer wall to rotate, and the transmission rod 6 drives the rotating plate 5 connected at one end to rotate. Through the rotation of the rotating plate 5, the other transmission rods 6 on one side are driven to move synchronously, so that multiple transmission rods 6 respectively drive the connected slide plates 8 to move around, and multiple slide plates 8 respectively drive the connected support blocks 12 to slide inside the support disk 2, so that the support block 12 drives the card block 13 connected on one side to expand inside the mounting seat 3, and then it is stuck inside to complete the fixation, thereby achieving The alarm device 4 can be quickly disassembled and assembled to provide an early warning effect to the power system. When the interior of the electric cabinet 1 is to be cooled, the handle 19 can be toggled to drive the turntable 18 to rotate inside the connecting frame 17. The turntable 18 is driven by the force to drive the connecting rod 22 on one side to move, and the connecting rod 22 is driven by the force to drive the blade 23 connected on one side to move, so that the blade 23 opens and closes at one end of the support ring 24. Through the movement of the blade 23, the air outlet in the support frame 14 is opened, and then the fan 15 inside the support frame 14 is started to dissipate heat to the inside of the electric cabinet 1. When the heat dissipation is completed, the ventilation rate can be effectively controlled by adjusting the opening and closing amplitude of the blade 23, so as to adjust the heat dissipation effect inside the electric cabinet 1 as needed. When encountering windy and rainy weather, the blade 23 can be closed to prevent external dust and rainwater from entering the interior of the electric cabinet 1, thereby achieving the effect of controlling the opening and closing of the air outlet to dissipate heat and protect the interior of the electric cabinet 1.
