Description
Technical Field
[0001] The utility model relates to the technical field of operation and maintenance management, and specifically to a monitoring mechanism and intelligent operation and maintenance risk management and control equipment for a substation. Background Art
[0002] Substations are places where voltage is changed. To transmit electricity generated by power plants to distant locations, the voltage must be stepped up to high voltage. Once the electricity reaches the user, the voltage is then stepped down as needed. This voltage stepping up and down is accomplished by substations. The main equipment in substations is switches and transformers. During operation, substations require monitoring, maintenance, and control to ensure their normal operation.
[0003] In the prior art, since there are many control switches in the substation, when monitoring the internal temperature, once one of the switches is damaged due to excessive temperature, a fire may even occur. Therefore, different temperature monitoring devices need to be installed for different switches. The following disadvantages will occur during monitoring: a large number of temperature monitoring devices are required, which greatly increases the monitoring cost. Once the temperature monitoring equipment is damaged, the cost of repairing the large number of equipment will also increase significantly, and the practicality is poor. Therefore, the present invention proposes a monitoring mechanism and a substation intelligent operation and maintenance risk control device to solve the above problems. Utility Model Content

[0006] A threaded rod is provided in the rotating sleeve of the lifting frame, a moving block is threadedly sleeved on the threaded rod, support plates are fixedly connected on both sides of the moving block, and a temperature sensor is fixedly installed on one side of the support plate.
[0007] Preferably, two long-stroke cylinders are provided and arranged symmetrically about the central plane of the lifting frame, and the long-stroke cylinders are electrically connected to the drive control box.

[0014] Compared with the prior art, the present invention has the following beneficial effects: by activating the output end of the large-stroke cylinder to extend, the sprocket is indirectly driven to move upward; the end of the chain fixedly connected to the fixed seat is the fixed end, and the end of the chain fixed to the lifting frame is the movable end. As the sprocket moves upward, it engages with the chain, and the movable end of the chain pulls the lifting frame upward for a certain distance, so that the temperature sensors installed on both sides of the lifting frame are at the same height as the first row of switches. Then, the rotation of the threaded rod drives the moving block to move along the axis of the threaded rod, thereby driving the temperature sensors fixed on one side of the support plate to pass through the first row of switches one by one, thereby achieving temperature monitoring and measurement of the first row of switches. Then, the output end of the large-stroke cylinder is further driven to extend, indirectly driving the temperature sensor to rise to the position of the second row of switches, and then the threaded rod is rotated in the opposite direction to achieve stable monitoring and measurement of the second row of switches. This reciprocating process can monitor multiple rows of switches one by one, and only one temperature sensor is needed to achieve full-range monitoring operation. In addition, temperature sensors are provided on both sides of the moving block, so that the temperature of the switches on both sides can be monitored simultaneously, thereby improving monitoring efficiency and expanding the monitoring area.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0023] For the purpose of simplicity and illustration, the principles of the embodiments are described primarily with reference to examples. In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring the understanding of these embodiments. In addition, all embodiments may be used in combination with each other.
[0024] Example 1: Please refer to Figures 1 to 4 The utility model provides a technical solution: a monitoring mechanism and substation intelligent operation and maintenance risk management equipment, including: a drive control box 1, a large-stroke cylinder 2 is provided on one side of the drive control box 1, a sprocket 3 is rotatably installed on the output end of the large-stroke cylinder 2, a chain 4 is engaged on the sprocket 3, one end of the chain 4 is fixedly connected to a fixed seat 5, and the other end of the chain 4 is fixedly connected to a lifting frame 6, a threaded rod 7 is rotatably sleeved in the lifting frame 6, a moving block 8 is threadedly sleeved on the threaded rod 7, support plates 9 are fixedly connected on both sides of the moving block 8, and a temperature sensor 10 is fixedly installed on one side of the support plate 9.
[0025] During monitoring, the output end of the large-stroke cylinder 2 can be extended by starting to indirectly push the sprocket 3 to move upward. The end of the chain 4 fixedly connected to the fixed seat 5 is the fixed end, and the end of the chain 4 fixed to the lifting frame 6 is the movable end. As the sprocket 3 moves upward, it engages with the chain 4, and then the movable end of the chain 4 pulls the lifting frame 6 upward for a distance. In this way, the temperature sensors 10 set on both sides of the lifting frame 6 and the first row of switches are at the same height. Then, the moving block 8 is driven to move along the axial direction of the threaded rod 7 by the rotation of the threaded rod 7, thereby driving the temperature sensor fixedly installed on one side of the support plate 9. The temperature sensor 10 passes through the first row of switches one by one, thereby realizing temperature monitoring and measurement of the first row of switches, and then continues to drive the output end of the large-stroke cylinder 2 to extend, indirectly driving the temperature sensor 10 to rise to the position of the second row of switches, and then makes the threaded rod 7 rotate in the opposite direction to realize stable monitoring and measurement of the second row of switches, and so on and so forth. In this way, multiple rows of switches can be monitored one by one, and only one temperature sensor 10 is needed to realize full-range monitoring operation. In addition, temperature sensors 10 are provided on both sides of the moving block 8, and thus the temperature of the switches on both sides can be monitored at the same time, thereby improving the monitoring efficiency and expanding the monitoring area.
[0026] Example 2: On the basis of Example 1, two long-stroke cylinders 2 are provided and symmetrically arranged about the central plane of the lifting frame 6. The long-stroke cylinders 2 are electrically connected to the drive control box 1. The long-stroke cylinders 2 are symmetrically arranged on both sides of the lifting frame 6, thereby simultaneously lifting and lowering both sides of the lifting frame 6, thereby improving the stability of the lifting frame 6. The bottom of the long-stroke cylinder 2 is fixedly connected to the base 11, the lower surface of the fixing seat 5 is fixedly connected to one side of the upper surface of the base 11, and a vertical rod 12 is fixedly installed on the other side of the upper surface of the base 11. The base 11 is fixed to the ground, thereby providing fixed support for the long-stroke cylinder 2. The fixed seat 5 and the vertical rod 12 are both fixedly mounted on the upper surface of the base 11, one side of the vertical rod 12 is fixedly connected to the limiting rail 13, the output end of the large-stroke cylinder 2 is fixedly connected to the U-shaped frame 14, the sprocket 3 is rotatably sleeved on the U-shaped frame 14, and both ends of the chain 4 are fixedly connected to the fixed seat 5 and the lifting frame 6 through the limiting rod 19. The vertical rod 12 fixes the limiting rail 13, the sprocket 3 is limited by the U-shaped frame 14, and the sprocket 3 is rotatably mounted on the U-shaped frame 14, one end of the chain 4 is fixedly connected to the fixed seat 5 through the limiting rod 19, and the other end of the chain 4 is fixedly connected to the end of the lifting frame 6 through the limiting rod 19.
[0027] During monitoring, the drive control box 1 drives the large-stroke cylinder 2 to operate, and the output end of the large-stroke cylinder 2 extends, thereby driving the sprocket 3 to move upward under the limit of the U-shaped frame 14, and the sprocket 3 engages with the chain 4 for transmission. One end of the chain 4 is fixedly connected to the fixed seat 5 through the limit rod 19, and this end is the fixed end. The other end of the chain 4 is fixedly connected to the end of the lifting frame 6 through the limit rod 19, and this end is the movable end. Therefore, when the sprocket 3 moves upward, it is engaged with the chain 4 to make the movable end of the chain 4 pull the lifting frame 6 to move. The lifting frame 6 slides upward for a distance under the limit of the limit rail 13, so that the temperature sensor 10 can be indirectly driven to be at the same height as the first row of switches, thereby facilitating the temperature monitoring of the first row of switches, and then the output end of the large-stroke cylinder 2 continues to extend, thereby indirectly driving the temperature sensor 10 to rise to the position of the second row of switches. This reciprocating movement allows the temperature sensor 10 to reach the position of each row of switches, thereby facilitating the monitoring of multiple rows of switches one by one.
[0028] Embodiment 3: On the basis of embodiment 2, the limiting rail 13 is slidably connected to the side wall of the lifting frame 6, the two sides of the threaded rod 7 are rotatably sleeved in the limiting bearing 15, one end of the threaded rod 7 is fixedly connected to the output end of the motor 16, and a limiting groove is provided on the side wall of the lifting frame 6. The limiting groove is adapted to the limiting rail 13, and the threaded rod 7 is limited by the limiting bearings 15 on both sides thereof. The threaded rod 7 is fixedly connected to the output end of the motor 16, thereby driving the threaded rod 7 to rotate. The lower surface of the motor 16 is fixedly connected to the lifting frame 6, and the bottom of the moving block 8 is slidably connected to the slide rail 17, which is fixedly mounted on the lifting frame. Inside the lowering frame 6, a wireless signal transmitter 18 is provided on the upper side of the moving block 8, and slide grooves are provided on both sides of the bottom of the moving block 8. The slide grooves are adapted to the slide rails 17, and the moving block 8 is limited by the slide rails 17. The wireless signal transmitter 18 is fixedly installed on the top of the lifting frame 6, so that the temperature data can be transmitted to the drive control box 1 through the wireless signal transmitter 18. The motor 16 and the wireless signal transmitter 18 are electrically connected to the drive control box 1, and the wireless signal transmitter 18 is electrically connected to the temperature sensor 10. A display screen is installed on the drive control box 1, which facilitates viewing the monitored temperature data.
[0029] When the lifting frame 6 lifts the temperature sensor 10 to the same height as the first row of switches, the motor 16 is started by driving the control box 1. The motor 16 drives the threaded rod 7 to rotate under the limit of the limit bearing 15, so that the threaded rod 7 drives the threaded sleeve movable block 8 thereon to move along the axial direction of the threaded rod 7 from one end of the threaded rod 7 to the other end, thereby monitoring the first row of switches and performing temperature monitoring and measurement one by one. Then the lifting frame 6 continues to lift, so that the temperature sensor 10 moves to a position with the same height as the second row of switches. At this time, the motor 16 is controlled to rotate in the opposite direction, so that the movable block 8 drives the temperature sensor 10 on the support plate 9 to perform temperature monitoring and measurement on the second row of switches one by one. This reciprocating process can monitor the temperature of multiple rows of switches one by one. Only one temperature sensor 10 is needed to achieve full-range monitoring operation. The temperature data is transmitted to the display screen on the drive control box 1 through the wireless signal transmitter 18, so that it is convenient for the operator to view.
