Description

Technical Field

[0001] This application relates to the field of time synchronization devices, and particularly to a time synchronization device for power system applications. Background Art

[0002] A time synchronization system is a system that can receive an external time reference signal and output a time synchronization signal and time information according to the required time accuracy. It can align and synchronize other clocks in the network. Generally speaking, time synchronization is to take technical measures to implement high-precision clock alignment for the clocks in the network. A substation needs to use a time synchronization device in cooperation. When the substation time synchronization device is used for a long time, its computing function will decline, resulting in an impact on the accuracy of time synchronization. In order to avoid time synchronization errors, it needs to be detected. Therefore, a substation time synchronization monitoring device is required.

[0003] Although the existing substation time synchronization monitoring devices can monitor the time synchronization device during use to prevent errors in its information synchronization, the substation time synchronization monitoring devices need to run continuously. When the device is used in hot weather, the internal heat cannot be dissipated in time, which easily causes damage to the electrical components inside the substation time synchronization monitoring device.

[0004] In view of the above related technologies, currently, a fan is mostly used to dissipate heat from the components. However, when the weather is too hot, the temperature of the components is high, and the heat dissipation efficiency of the fan is very low, unable to dissipate heat from the components in time, affecting the normal operation of the components and even damaging the components.

Every four sections of the winding ropes are set into two groups. Each group of winding ropes is connected to one end of the absorbent paper. The two winding ropes in the same group are respectively connected to two corners of the absorbent paper. The guiding roller is arranged in front of the winding roller. When the guiding roller descends to abut against the end of the metal plate, the absorbent paper fits against the upper and lower sides of the metal plate.

[0011] Optionally, the drying part further includes a laying rack arranged to be lifted and lowered on the drying rack, a laying roller arranged on the laying rack, and a feeding group for controlling the feeding of the laying roller.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. The fan is used to blow air to dissipate heat for the time synchronization monitoring mechanism. However, in the actual heat dissipation process, if the temperature drops slowly or the fan does not dissipate heat effectively after a long period of blowing, the heating component needs to be controlled to accelerate the cooling effect. 2. The nozzle sprays liquid cryogenic gas at a 45° angle to sweep the surface. After the spraying is completed, the temperature of the metal plate can be close to -50°C, so the metal plate is pre-cooled. When the metal plate is pre-cooled and placed for a period of time, the conveying electric push rod is controlled to continue to push the metal plate to move. Through the cooperation of the two winding motors and the two winding rollers, the absorbent paper moves to the front of the front end of the metal plate. The bracket is continued to be controlled to move forward, and the winding rope is continued to be released. The metal plate begins to fold the absorbent paper until the tail end of the metal plate moves to a position close to the guide roller. At this time, the guide roller is controlled to move downward. The guide roller moves the two ends of the absorbent paper toward the upper and lower sides of the tail end of the metal plate respectively until the guide roller completely guides the absorbent paper to fit the metal plate. The absorbent paper begins to dry the upper and lower sides of the metal plate. When the drying of the absorbent paper is completed, the two winding rollers begin to rotate and the guide roller moves upward to wind the absorbent paper toward one of the winding rollers until the winding rope is pulled to the position of the metal plate. The metal plate is dry and can continue to be pushed into the box; 3. The structure of the transfer part can achieve the effect of transporting the metal plate step by step above the fan.

Detailed Description of the Invention

[0018] The following Figures 1-4 further describes the present application in detail with reference to the attached

[0019] The embodiment of the present application discloses a time synchronization device for power system applications. Refer to Figures 1-4, A time synchronization device for power system applications includes a box body 1 and a time synchronization monitoring mechanism 2 disposed within the box body 1. The time synchronization monitoring mechanism 2 includes a synchronization source input module, a CPU processing and management module, a synchronization signal output module, a conventional signal conditioning module, an on-line monitoring module, a power supply module, a general-purpose interface bus, and a human-machine interaction module. The synchronization source input module is unidirectionally electrically connected to the CPU processing and management module through the general-purpose interface bus. The CPU processing and management module, the on-line monitoring module, and the human-machine interaction module are bidirectionally electrically connected through the general-purpose interface bus. The conventional signal conditioning module is unidirectionally electrically connected to the CPU processing and management module through the general-purpose interface bus. The power supply module supplies power to the synchronization source input module, the CPU processing and management module, the synchronization signal output module, the conventional signal conditioning module, the on-line monitoring module, and the human-machine interaction module through the general-purpose interface bus. The specific operation conditions will not be elaborated in this embodiment.

[0020] A temperature sensor for measuring the temperature of the time synchronization monitoring mechanism 2 and a heat dissipation mechanism for dissipating heat from the time synchronization monitoring mechanism 2 are also disposed within the box body 1; the temperature sensor is used to monitor the temperature of the time synchronization monitoring mechanism 2. In this embodiment, the temperature sensor can be in contact with or just close to the time synchronization monitoring mechanism 2. When the time synchronization monitoring mechanism 2 overheats, the temperature sensor can monitor that the temperature exceeds the set value, and thus heat dissipation is required.

[0021] The heat dissipation mechanism includes an air-cooling component and an acceleration component for accelerating the heat dissipation speed; the air-cooling component includes a fan 36 disposed below the time synchronization monitoring mechanism 2, and the fan 36 is used to blow air for heat dissipation of the time synchronization monitoring mechanism 2. However, in the actual heat dissipation process, if the temperature drops slowly, or the heat dissipation effect of the fan 36 blowing air for a long time is not good, then the heating component needs to be controlled to start accelerating the cooling effect; the acceleration component includes an acceleration box 3, a metal plate 5 for conducting heat and cooling the time synchronization monitoring mechanism 2, an energy supply part for providing a cold source, and a drying part for drying the metal plate 5; the acceleration box 3 is disposed on the back of the box body 1 and does not affect the normal wiring work of the time synchronization monitoring mechanism 2. A sealing part is provided between the acceleration box 3 and the box body 1. The box body 1 is provided with an acceleration port 4, and the acceleration box 3 covers the outside of the acceleration port 4. The metal plate 5 enters the box body 1 from the acceleration port 4, and in this embodiment, there is just enough space for the metal plate 5 to enter between the fan 36 and the time synchronization monitoring mechanism 2. When the metal plate 5 enters above the fan 36, the top of the metal plate 5 just contacts the lower part of the time synchronization monitoring mechanism 2. The energy supply part is used to pre-cool the metal plate 5. After the pre-cooled metal plate 5 contacts the time synchronization monitoring mechanism 2, it can quickly cool the time synchronization monitoring mechanism 2, greatly improving the heat dissipation speed. At this time, the fan 36 can work depending on the situation. Generally, the fan 36 does not need to work anymore.

[0022] The closing part includes a closing plate 6 arranged to move up and down at the acceleration port 4 and a closing electric push rod 7 for controlling the movement of the closing plate 6. A rubber ring can also be arranged on the outer wall of the closing plate 6 to further ensure the separation effect between the acceleration box 3 and the box body 1. When the metal plate 5 needs to enter the box body 1 from the acceleration box 3, the closing plate 6 needs to be opened.

[0023] The energy supply part includes a bracket 8 movably arranged in the acceleration box 3, a wiping group for wiping the metal plate 5, a conveying electric push rod 9 for controlling the sliding of the bracket 8, a storage tank 10 for storing compressed air, and a nozzle 11. The metal plate 5 is arranged on the bracket 8. The bracket 8 is in a frame shape, and a baffle 12 is arranged at one end of the bracket 8 close to the conveying electric push rod 9. The nozzle 11 is arranged obliquely and faces the metal plate 5 directly. The storage tank 10 is arranged in the external environment. The conveying electric push rod 9 is arranged at a position in the acceleration box 3 far from the acceleration port 4. The height dimension of the abutting plate is just adapted to the metal plate 5, that is, when the metal plate 5 is placed on the bracket 8, the upper surface of the metal plate 5 is just flush with the upper surface of the baffle 12. The bracket 8 is arranged in a concave frame shape, and the bottom of the metal plate 5 is also exposed; the setting of the abutting plate is mainly to ensure that during the wiping process of the wiping group on the metal plate 5, since the metal plate 5 is moving towards the inside of the box body 1, the frictional force between the wiping group and the metal plate 5 may cause the metal plate 5 to move towards the direction of the baffle 12, but due to the existence of the baffle 12, the position of the metal plate 5 will not change.

[0024] The wiping group is arranged at a position before the metal plate 5 moves towards the nozzle 11. The wiping group includes a drying cloth 13 arranged to move up and down in the acceleration box 3. The drying cloth 13 is used to wipe the metal plate 5. The main function of the drying cloth 13 for wiping the surface of the metal plate 5 is to avoid impurities on the metal plate 5. If the metal plate 5 is sprayed with liquid cryogenic gas subsequently, first, it will affect the cleanliness of the metal plate 5, resulting in subsequent contamination of the time synchronization monitoring mechanism 2 in the box body 1. Second, if there are impurities on the surface of the metal plate 5, the spraying of the liquid cryogenic gas on the metal plate 5 is uneven, resulting in uneven temperature, affecting the cooling effect; in this embodiment, both the nozzle 11 and the storage tank 10 are arranged upside down, and the inclination angle of the nozzle 11 is set to 45°. The nozzle 11 sprays liquid cryogenic gas (the temperature can be as low as -50°C), and the optimal distance from the metal block is 10 - 15 cm, and it sweeps the surface at a 45° angle to avoid local overcooling caused by concentrating on one point. The temperature of the metal plate 5 after spraying can be close to -50°C, so as to achieve the effect of pre-cooling the metal plate 5. And during the spraying process, the conveying electric push rod 9 gradually conveys the bracket 8 and the metal plate 5 forward to ensure uniform temperature on the metal plate 5.

[0025] Since the temperature of the metal plate 5 is low, in order to avoid condensation or dew formation, it is necessary to leave the metal plate 5 stationary for a period of time and to perform a water absorption operation on the surface of the metal plate 5. Since the inside of the box body 1 is basically in a dry environment, the probability of condensation occurring inside the box body 1 is low, but it is also necessary to ensure that there is no moisture on the metal plate 5. In this embodiment, a heat-insulating material can be coated on the bottom of the metal plate 5 to further reduce the probability of condensation at the bottom of the metal plate 5. The drying part is mainly used to dry the metal plate 5; the drying part includes a drying rack 14, a plurality of absorbent papers 15 movably arranged on the drying rack 14, and a guiding group for guiding the absorbent papers 15. The area of the absorbent paper 15 is larger than the area of the metal plate 5. The absorbent paper 15 moves along the vertical direction. When the metal plate 5 moves to the position of the absorbent paper 15, the absorbent paper 15 is lowered, and as the metal plate 5 continues to move, the guiding plate guides the absorbent paper 15 to the upper and lower sides of the metal plate 5. The length and width dimensions of the absorbent paper 15 are both larger than the length and width dimensions of the metal plate 5, so that the absorbent paper 15 can wrap the metal plate 5. In this embodiment, the moving direction of the absorbent paper 15 is along the vertical direction.

[0026] The guiding group includes two winding rollers 16, two winding motors 17, a plurality of winding ropes 18, two guiding frames 19 arranged vertically on the drying rack 14, and a guiding roller 20 rotatably arranged on the guiding frame 19. The two guiding frames 19 are respectively arranged on the upper and lower sides of the metal plate 5. The two winding rollers 16 are respectively arranged on the upper and lower sides of the metal plate 5. Every four winding ropes 18 are set into two groups. Each group of winding ropes 18 is connected to one end of the absorbent paper 15. The two winding ropes 18 in the same group are respectively connected to two corners of the absorbent paper 15. The guiding roller 20 is arranged in front of the winding roller 16. When the guiding roller 20 descends to abut against the end of the metal plate 5, the absorbent paper 15 fits against the upper and lower sides of the metal plate 5. In this embodiment, every four winding ropes 18 respectively fix the four corners of the absorbent paper 15 to ensure the stability of the absorbent paper 15 during movement. Moreover, in the initial state, the four winding ropes 18 are in the moving direction of the metal plate 5. After the absorbent paper 15 finishes working, the metal plate 5 can pass through between the two corresponding winding ropes 18. Since the area of the absorbent paper 15 is larger than the area of the metal plate 5, the gap between the two corresponding winding ropes 18 is significantly larger than the width dimension of the metal plate 5, and the winding ropes 18 will not affect the normal movement of the metal plate 5. A plurality of absorbent papers 15 are arranged at intervals.

[0027] The winding motor 17 is set as a servo motor or a stepper motor. The two winding motors 17 rotate at the same frequency. The length direction of the guiding roller 20 is arranged along the width direction of the metal plate 5. The position of the guiding roller 20 is close to the winding roller 16 but in front of the winding roller 16. In this embodiment, the direction in which the metal plate 5 moves from the acceleration box 3 towards the inside of the box body 1 is defined as the front. When the metal plate 5 is pre-cooled and left for a period of time, at this time, the conveying electric push rod 9 is controlled to continue pushing the metal plate 5 to move. Through the mutual cooperation of the two winding motors 17 and the two winding rollers 16, the absorbent paper 15 moves to the front of the front end of the metal plate 5. The bracket 8 is continuously controlled to move forward, and the winding rope 18 is continuously released. The metal plate 5 starts to fold the absorbent paper 15 until the tail end of the metal plate 5 moves to a position close to the guiding roller 20. At this time, the guiding roller 20 is controlled to move downward. The guiding roller 20 moves the two ends of the absorbent paper 15 towards the upper and lower sides of the tail end of the metal plate 5 respectively until the guiding roller 20 completely guides the absorbent paper 15 to be attached to the metal plate 5. The absorbent paper 15 starts to dry the upper and lower sides of the metal plate 5. When the drying work of the absorbent paper 15 is completed, the two winding rollers 16 start to rotate and the guiding roller 20 moves upward to wind the absorbent paper 15 towards one of the winding rollers 16 until the winding rope 18 is pulled to the position of the metal plate 5. The metal plate 5 is dried and can continue to be pushed into the box body 1.

[0028] Since a dry environment needs to be ensured inside the box body 1, the upper surface of the metal plate 5 needs to be dried. In this embodiment, it is default that no condensation phenomenon occurs on the bottom coating of the metal plate 5. The drying part further includes a laying frame 21 that is vertically arranged on the drying frame 14, a laying roller 22 arranged on the laying frame 21, and a feeding group for controlling the feeding of the laying roller 22. The length direction of the laying roller 22 is arranged along the width direction of the metal plate 5. A plurality of laying holes 23 are arranged on the side of the laying roller 22 facing the metal plate 5. The plurality of laying holes 23 are equidistantly arranged along the length direction of the laying roller 22. The laying roller 22 is filled with silica gel particles. The silica gel particles have high hygroscopicity, are non-toxic and chemically inert. Therefore, even if condensation occurs on the upper surface of the metal plate 5 inside the box body 1, the silica gel particles can quickly absorb water and dry. And even when the lower part of the time synchronization monitoring mechanism 2 contacts the upper surface of the metal plate 5, some silica gel particles may adhere to the lower part of the time synchronization monitoring mechanism 2. However, since the silica gel particles are non-corrosive and the adhesion amount is extremely small, and the particle size of the silica gel particles is small, very few silica gel particles will move due to the friction between the time synchronization monitoring mechanism 2 and the metal plate 5. Therefore, silica gel particles are selected in this embodiment to pre-treat the upper surface of the metal plate 5.

[0029] The number of laying holes 23 does not need to be excessive, as long as it can ensure that the inside of the metal plate 5 can be normally and evenly laid. The feeding group includes an arc plate 24, a gear 25, a ring gear 26, a feeding motor 27 and a feeding plate 28 that are rotatably arranged on the laying frame 21. The arc plate 24 fits and rotates with the laying roller 22, and the cross-sectional arc of the arc plate 24 is not less than 180°. The feeding motor 27 is arranged on the laying frame 21 and controls the rotation of the gear 25. The ring gear 26 is meshed and connected with the gear 25. The ring gear 26 is arranged on the outer wall of the arc plate 24. The feeding plate 28 is fixed at the end of the arc plate 24. In the initial state, the arc plate 24 blocks the laying hole 23. When the arc plate 24 rotates to be separated from the laying hole 23, the feeding plate 28 moves to a position close to the metal plate 5 and levels the silica gel particles on the metal plate 5. The cross-sectional arc of the ring gear 26 is not less than 90°, and it is necessary to ensure that there is enough distance to ensure that the arc plate 24 separates from the bottom of the laying hole 23, so as to open the laying hole 23. The main function of the arc plate 24 is to block the laying hole 23.

[0030] When the metal plate 5 moves below the laying roller 22, at this time, the feeding motor 27 controls the rotation of the gear 25. The gear 25 drives the ring gear 26 to rotate. The ring gear 26 drives the arc plate 24 to move and the arc plate 24 moves away from the laying hole 23. The silica gel particles in the laying roller 22 start to fall from the laying hole 23 onto the metal plate 5. At the same time, the scraper moves above the metal plate 5. And in this embodiment, when the arc plate 24 separates from the laying hole 23 during the movement process, the scraper moves to a state perpendicular to the metal plate 5, and the bottom end of the scraper is close to the position of the metal plate 5. As the metal plate 5 moves, the scraper can play a role in leveling the silica gel particles. At this time, it is necessary to start the closing plate 6 and continue to push the bracket 8, and the metal plate 5 enters the box body 1.

[0031] The box body 1 is also provided with a transfer part for transferring the metal plate 5 between the air-cooling component and the time synchronization monitoring mechanism 2. The transfer part includes a slide bar 31, two sliders 32, a first electromagnet 33, a two-way oil cylinder 34 and two second electromagnets 35. One end of the slide bar 31 is fixedly connected to the box body 1, and the other end of the slide bar 31 is close to the position of the air-cooling component. The two second electromagnets 35 are respectively fixedly connected to the two sliders 32. The second electromagnet 35 adsorbs on the slide bar 31. The first electromagnet 33 is arranged on any one of the sliders 32 and adsorbs on the bottom of the metal plate 5. The two ends of the two-way oil cylinder 34 are respectively connected to the two sliders 32. The exposed part of the slide bar 31 below the bracket 8 is inside.

[0032] In this embodiment, a metal that can be magnetically attracted needs to be selected. Therefore, when the metal plate 5 enters the box body 1, the first electromagnet 33 starts to adsorb the bottom of the metal plate 5. The second electromagnet 35 at the front end is powered off and separated from the slide rod 31, and the second electromagnet 35 at the rear end is powered on and adsorbed to the slide rod 31. The two-way oil cylinder 34 controls the slider 32 at the front end to move forward, and the metal plate 5 moves upward towards the fan 36. Then the second electromagnet 35 at the rear end is powered off, the second electromagnet 35 at the front end is powered on and adsorbs to the slide rod 31, and the two-way oil cylinder 34 controls the slider 32 at the rear end to move forward, thereby gradually conveying the metal plate 5 forward. When the front end of the metal plate 5 moves above the fan 36, since the fan 36 in this embodiment adopts a structure with a housing, it also has the effect of supporting the metal plate 5. At this time, the first electromagnet 33 is powered off and the two-way oil cylinder 34 moves backward according to the above steps until it moves to the acceleration port 4, and then by analogy with the above steps, the metal plate 5 is conveyed above the fan 36 step by step and abuts against the lower part of the time synchronization monitoring mechanism 2. In this embodiment, the structure of the transfer part is selected mainly because if the bracket 8 adopts the structure of an electric push rod, first, there is no space in the box body 1 for installation, and second, the structure of the transfer part can achieve the effect of conveying the metal plate 5 above the fan 36 step by step.

[0033] After the metal plate 5 contacts the lower part of the time synchronization monitoring mechanism 2, at this time, the fan 36 does not need to be turned on, and heat transfer starts between the metal plate 5 and the time synchronization monitoring mechanism 2, which can quickly cool and dissipate heat from the time synchronization monitoring mechanism 2.

[0034] The wiping group further includes a material receiving box 29 and an air extraction member 30. The output end of the air extraction member 30 is communicated with the bottom of the material receiving box 29 opposite to it. The material receiving box 29 is located below the wiping group. When the cooling operation of the metal plate 5 is completed, at this time, the metal plate 5 is conveyed into the acceleration box 3 through the transfer part and is conveyed onto the bracket 8. Then, subsequently, the dry cloth 13 can be abutted against the metal plate 5, and the conveying direction of the conveying electric push rod 9 is controlled to ensure that the metal plate 5 is completely located on the bracket 8. At this time, the dry cloth 13 is pulled upward as long as it can wipe the silica gel particles on the metal plate 5. As the bracket 8 moves, the dropped silica gel particles are affected by the air extraction member 30, and the silica gel particles fall into the material receiving box 29. The air extraction member 30 can be selected as the structure of an air extractor to complete the collection effect of the silica gel particles.

[0035] The implementation principle of a time synchronization device for power system applications in an embodiment of this application is as follows: The nozzle 11 sprays liquid cryogenic gas to sweep the surface at an angle of 45°. After the spraying is completed, the temperature of the metal plate 5 can be close to -50°C, thus achieving the effect of pre-cooling the metal plate 5. When the pre-cooling of the metal plate 5 is completed and it is placed for a period of time, at this time, control the conveying electric push rod 9 to continue pushing the metal plate 5 to move. Through the mutual cooperation of two winding motors 17 and two winding rollers 16, the absorbent paper 15 moves to the front of the front end of the metal plate 5. Continue to control the bracket 8 to move forward and continue to release the winding rope 18. The metal plate 5 starts to fold the absorbent paper 15 until the tail end of the metal plate 5 moves to a position close to the guide roller 20. At this time, control the guide roller 20 to move downward. The guide roller 20 moves the two ends of the absorbent paper 15 to the upper and lower sides of the tail end of the metal plate 5 respectively until the guide roller 20 completely guides the absorbent paper 15 to fit with the metal plate 5. The absorbent paper 15 starts to dry the upper and lower sides of the metal plate 5. When the drying work of the absorbent paper 15 is completed, the two winding rollers 16 start to rotate and the guide roller 20 moves upward to wind the absorbent paper 15 towards one of the winding rollers 16 until the winding rope 18 is pulled to the position of the metal plate 5. The metal plate 5 is dried and can continue to be pushed into the box body 1.

[0036] When the metal plate 5 moves below the laying roller 22, at this time, the feeding motor 27 controls the gear 25 to rotate. The gear 25 drives the ring gear 26 to rotate. The ring gear 26 drives the arc plate 24 to move and the arc plate 24 moves away from the laying hole 23. The silica gel particles in the laying roller 22 start to fall from the laying hole 23 onto the metal plate 5. At the same time, the scraper moves above the metal plate 5. And in this embodiment, when the arc plate 24 separates from the laying hole 23 during the movement process, the scraper moves to a state perpendicular to the metal plate 5, and the bottom end of the scraper is close to the position of the metal plate 5. As the metal plate 5 moves, the scraper can achieve the effect of making the silica gel particles uniform. At this time, it is necessary to start the closing plate 6 and continue to push the bracket 8, and the metal plate 5 enters the box body 1.

[0037] The structure of the transmission part can achieve the effect of transporting the metal plate 5 step by step above the fan 36. After the metal plate 5 comes into contact with the lower part of the time synchronization monitoring mechanism 2, at this time, there is no need to turn on the fan 36. The metal plate 5 and the time synchronization monitoring mechanism 2 start to conduct heat transfer, and can quickly cool down and dissipate heat from the time synchronization monitoring mechanism 2.

[0038] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
