Description

Technical Field

[0001] This utility model relates to the field of power auxiliary equipment technology, specifically a quantum communication terminal device for a low-voltage distribution cabinet with a physical locking structure. Background Technology

[0002] With the deep integration of smart grids and quantum communication technology, quantum secure switches, as core equipment to ensure the secure transmission of power data, are widely used in low-voltage distribution cabinets. Through technologies such as quantum key distribution and quantum encryption, quantum secure switches build a communication channel for the power system that is "uninterceptable and unbreakable," effectively preventing data leakage and malicious tampering, and significantly improving the security and reliability of power grid operation.

[0003] A search revealed that patent publication number CN110418213A discloses a quantum optical switch. Several quantum optical switch bodies are housed within a cabinet. Heat exchange vents are located on the left and right sides of each switch body. A water-cooled outdoor unit is located on the top of the cabinet. An inner water-cooled spiral tube is wrapped around the outer side of each switch body in the left and right circumferential direction. This inner water-cooled spiral tube extends spirally from back to front, with both ends extending to the right. A return pipe extending horizontally backward is connected to the front end of the inner water-cooled spiral tube. The rear ends of the return pipe and the inner water-cooled spiral tube are respectively connected to vertically upward-extending main flow pipes. The two main flow pipes extend vertically upward, with their upper ends extending out of the cabinet and connecting to the inlet and outlet of the water-cooled outdoor unit, respectively. This invention uses an inner water-cooled spiral tube spirally wound around the outside of the quantum optical switch body for sealed water-cooling heat dissipation, achieving full-coverage heat dissipation of the quantum optical switch body in one circumferential direction. This provides excellent heat dissipation and helps ensure constant-temperature operation of the quantum optical switch body.

[0004] However, in practical applications, traditional low-voltage distribution cabinets often use bolts or simple slots to fix quantum secure switches. While this fixes the equipment, it results in cumbersome disassembly and assembly, and low maintenance efficiency. Workers need to repeatedly remove screws with tools, which is time-consuming and labor-intensive. Frequent disassembly and assembly can also cause wear and tear on the cabinet or equipment interfaces, reducing the equipment's lifespan. Furthermore, low-voltage distribution cabinets face complex working environments, such as mechanical vibrations in industrial plants, bumps during transportation, and impacts from the start-up and shutdown of power equipment. These vibrations and impacts can easily cause the precision electronic components inside the quantum secure switch to loosen, fail to connect, or even be damaged, thus affecting the stability and security of quantum communication. Therefore, a quantum communication terminal device for low-voltage distribution cabinets with a physical locking structure is designed. Utility Model Content

[0005] In view of the defects or deficiencies of quantum communication terminal equipment for low-voltage distribution cabinets, the purpose of this utility model is to provide a quantum communication terminal equipment for low-voltage distribution cabinets with a physical locking structure, which can quickly complete the installation and disassembly of quantum security switches without the need for external tools, greatly shorten maintenance time, improve the emergency response speed of the power system, and reduce equipment downtime.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

The physical locking mechanisms are connected to a quantum security switch through shock absorbers.

[0008] The physical lock fixing mechanism is provided with a pressing component and a locking component. When the pressing component moves downward along the Y-axis, it will exert a certain pressing force on the locking component in the X-axis direction, thereby locking the locking component against the pressing component. The physical lock fixing mechanism is provided with a support block for positioning and installing the pressing component. The physical lock fixing mechanism is also provided with an unlocking component for unlocking the pressing component after exerting a certain pressing force on the locking component in the X-axis direction. The unlocking component is located between the locking component and the support block.

[0009] Preferably, the support block is installed at both ends of the upper surface of the fixed base plate, and a plum blossom-shaped positioning hole is provided at the center of the end wall of the support block.

[0010] Preferably, the extrusion assembly is provided with an installation plate, and the installation plate is located on top of the plum blossom-shaped positioning posts. Plum blossom-shaped positioning posts are installed at both ends of the lower surface of the installation plate, and the other end of the plum blossom-shaped positioning posts is installed in the plum blossom-shaped positioning holes. An extrusion plate is installed on one outer wall of the installation plate, and a slot is formed on one outer wall of the extrusion plate.

[0011] Preferably, the locking assembly is provided with a side plate, which is installed on the other side of the upper surface of the fixed base plate. A rectangular limiting slot is provided on the upper outer wall of the side plate, and a card plate is provided in the rectangular limiting slot. A second limiting plate is installed on one end of the card plate, and the other end of the card plate is located in the card slot. A protrusion is provided on one side of the lower surface of the card plate.

[0012] Preferably, a guide post is installed on the outer wall of the protrusion, and the other end of the guide post passes through the guide hole on the outer wall of the side plate and is connected to the first limiting plate. The guide post, the first limiting plate and the protrusion are all connected by thread. A spring is sleeved on the outer side of the outer wall of the guide post, and the spring is located between the side plate and the protrusion.

[0013] Preferably, the unlocking component is provided with two first connecting plates and two second connecting plates. The two first connecting plates are respectively located at the front and rear ends of the upper surface of the fixed base plate, and the two second connecting plates are respectively located on both sides of the front end of the fixed base plate. A rotating roller is installed between each pair of adjacent first connecting plates, and the rotating roller is located on one side of the protrusion.

[0014] Preferably, a push plate is provided on the circumferential outer wall of the rotating roller, and the connecting shafts on both ends of the rotating roller pass through the bearings on the outer walls of the two first connecting plates respectively. A turbine is provided on the connecting shaft on one end of the rotating roller, and worm gears are provided between each pair of adjacent second connecting plates. Both ends of the worm gears pass through the bearings on the outer walls of the two second connecting plates respectively, and a rotating handwheel is provided at one end of the worm gear. The turbine gear and the worm gear are meshed together.

[0015] Preferably, the top end of the shock absorber is fixedly connected to the bottom end of the quantum security switch by fastening bolts, and the bottom end of the shock absorber is fixedly connected to the top end of the mounting plate by fastening bolts.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. In this utility model, through a series of coordinated structural arrangements, when the operator fixes the quantum safe switch, the operator moves the quantum safe switch downwards in the Y-axis direction. The compression assembly connected to the bottom of the quantum safe switch via a shock absorber is positioned directly above the support block. During the process of aligning the plum blossom-shaped positioning post with the plum blossom-shaped positioning hole on the support block and installing the plum blossom-shaped positioning post into the plum blossom-shaped positioning hole, the compression plate on the compression assembly exerts a certain compression force on the locking plate on the locking assembly in the X-axis direction. The locking plate will displace in a certain direction. When the plum blossom-shaped positioning post is fully installed into the plum blossom-shaped positioning hole, the locking plate, under the action of the spring return force, will cause one end of the locking plate to engage in the slot. At this time, the locking assembly locks the compression assembly, thus completing the installation and fixation of the quantum safe switch. When the operator disassembles the quantum safe switch... The operator rotates the handwheel on the unlocking component. This rotation indirectly drives the push plate on the rotating roller to rotate. The push plate's rotation exerts pressure on the protrusion on the locking component along the X-axis, causing the locking plate to shift in a certain direction. One end of the locking plate then moves out of the slot. Once this end is out, the operator moves the quantum security switch upwards along the Y-axis, completing the disassembly. This invention allows for the rapid installation and disassembly of the quantum security switch without the need for external tools. Compared to traditional bolt fastening methods, this significantly reduces maintenance time and labor costs. This tool-free disassembly feature is particularly suitable for emergency fault diagnosis and routine maintenance, improving the emergency response speed of the power system and reducing equipment downtime.

[0018] 2. In this utility model, through a series of coordinated structural arrangements, the shock absorber can buffer and reduce vibration of the quantum secure switch. The buffering effect of the shock absorber effectively alleviates the mechanical damage of vibration to the quantum secure switch, avoids problems such as solder joint detachment and interface loosening caused by long-term vibration, reduces the impact of vibration on the precision components inside the quantum secure switch, significantly reduces the probability of equipment failure caused by vibration, ensures the continuous and stable operation of the quantum communication system, extends the service life of the quantum secure switch, and reduces the maintenance cost of the equipment throughout its entire life cycle.

A support frame 110 is installed at the bottom of the low-voltage distribution cabinet 100. Physical locking mechanisms 300 are installed on both sides of the top of the support frame 110. The physical locking mechanisms 300 are connected to a quantum secure switch 200 through a shock absorber 400. The shock absorber 400 can buffer and reduce vibration on the quantum secure switch. The buffering effect of the shock absorber 400 effectively alleviates the mechanical damage of vibration to the quantum secure switch, avoids problems such as solder joint detachment and interface loosening caused by long-term vibration, reduces the impact of vibration on the precision components inside the quantum secure switch 200, significantly reduces the probability of equipment failure caused by vibration, ensures the continuous and stable operation of the quantum communication system, extends the service life of the quantum secure switch 200, and reduces the maintenance cost of the equipment throughout its entire life cycle.

[0038] The physical lock fixing mechanism 300 is provided with a pressing component 310 and a locking component 330. When the pressing component 310 moves downward along the Y-axis, it will exert a certain pressing force on the locking component 330 in the X-axis direction, which will cause the locking component 330 to lock the pressing component 310.

The plum blossom-shaped positioning posts 312 and the plum blossom-shaped positioning hole 351 not only play a role in limiting and guiding the extrusion assembly 310 to be installed on the support block 350, but also play a role in limiting and guiding the extrusion plate 313 to extrude the clamping plate 331, thus avoiding misalignment during the extrusion process of the extrusion plate 313 to extrude the clamping plate 331.

[0041] The locking assembly 330 is provided with a side plate 333, which is installed on the other side of the upper surface of the fixed base plate 320. A rectangular limiting slot is provided on the upper part of the outer wall of the side plate 333, and a locking plate 331 is provided in the rectangular limiting slot. The rectangular limiting slot can limit and guide the movement of the locking plate 331.

[0042] A guide post 335 is installed on the outer wall of the protrusion 332. The other end of the guide post 335 passes through the guide hole on the outer wall of the side plate 333 and is connected to the first limiting plate 334. The guide post 335, the first limiting plate 334 and the protrusion 332 are all threadedly connected. A spring 337 is sleeved on the outer side of the outer wall of the guide post 335 and the spring 337 is located between the side plate 333 and the protrusion 332. The guide post 335 and the guide hole can limit and guide the movement of the protrusion 332.

[0043] The unlocking component 340 is provided with two first connecting plates 341 and two second connecting plates 345. The two first connecting plates 341 are respectively located at the front and rear ends of the upper surface of the fixed base plate 320, and the two second connecting plates 345 are respectively located on both sides of the front end of the fixed base plate 320. A rotating roller 342 is installed between each pair of adjacent first connecting plates 341, and the rotating roller 342 is located on one side of the protrusion 332.

[0044] A push plate 343 is provided on the circumferential outer wall of the rotating roller 342. The connecting shafts on both ends of the rotating roller 342 pass through the bearings on the outer walls of the two first connecting plates 341 respectively. A worm gear 344 is provided on the connecting shaft on one end of the rotating roller 342. Worms 347 are provided between each pair of adjacent second connecting plates 345. Both ends of the worm gear 347 pass through the bearings on the outer walls of the two second connecting plates 345 respectively. A rotating handwheel 346 is provided on one end of the worm gear 347. The worm gear 344 and the worm gear 347 are meshed. When the rotating handwheel 346 rotates, it will drive the worm gear 347 to rotate. When the worm gear 347 rotates, it will drive the worm gear 344 to rotate. When the worm gear 344 rotates, it will drive the rotating roller 342 to rotate. When the rotating roller 342 rotates, it will drive the push plate 343 to rotate.

[0045] The top of the shock absorber 400 is fixedly connected to the bottom of the quantum security switch 200 by fastening bolts, and the bottom of the shock absorber 400 is fixedly connected to the top of the mounting plate 311 by fastening bolts.

[0046] Working principle: When the operator fixes the quantum secure switch 200, the operator moves the quantum secure switch 200 downward in the Y-axis direction. The compression assembly 310, connected to the bottom of the quantum secure switch 200 via the shock absorber 400, is positioned directly above the support block 350. The operator aligns the plum blossom-shaped positioning post 312 with the plum blossom-shaped positioning hole 351 on the support block 350 and installs the plum blossom-shaped positioning post 312 into the plum blossom-shaped positioning hole 351. During this process, the compression plate 31 on the compression assembly 310... 3. A certain compressive force will be applied to the locking plate 331 on the locking assembly 330 in the X-axis direction. The locking plate 331 will shift in a certain direction. When the plum blossom-shaped positioning post 312 is fully installed into the plum blossom-shaped positioning hole 351, the locking plate 331 will be engaged into the slot 314 under the rebound force of the spring 337. At this time, the locking assembly 330 locks the compression assembly 310, thus completing the installation and fixation of the quantum security switch 200. When the staff disassembles the quantum security switch 200... During disassembly, the operator rotates the handwheel 346 on the unlocking component 340. The rotation of the handwheel 346 indirectly drives the push plate 343 on the rotating roller 342 to rotate. During this rotation, the push plate 343 exerts a certain pressure on the protrusion 332 on the locking component 330 in the X-axis direction. This pressure causes the locking plate 331 to shift in a certain direction, resulting in one end of the locking plate 331 moving out of the slot 314. When one end of 31 is removed from the slot 314, the staff can move the quantum security switch 200 upward in the Y-axis direction to complete the disassembly of the quantum security switch 200. Thus, this utility model can quickly complete the installation and disassembly of the quantum security switch 200 without the aid of external tools. Compared with the traditional bolt fastening method, it greatly shortens the maintenance time and reduces the maintenance labor cost. This tool-free disassembly and assembly feature is especially suitable for emergency fault diagnosis and daily maintenance scenarios, improves the emergency response speed of the power system, and reduces equipment downtime.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
