Description

Technical Field

[0001] This utility model relates to the field of relay protection device technology, and in particular to a microcomputer relay protection device for power detection. Background Technology

[0002] Relay protection devices are crucial intelligent devices in modern power systems. They integrate computer technology, digital signal processing technology, and power system protection technology to monitor, protect, and control various electrical equipment in the system (such as generators, transformers, transmission lines, busbars, capacitors, reactors, motors, etc.).

[0003] In special circumstances, relay protection devices need to be installed outdoors, which requires extremely high requirements for their mechanical and electrical design. For example, they need to be installed in places such as wind power, photovoltaic fields, and railway traction substations. Currently, outdoor relay protection device systems are installed in cabinets, and small house structures are built on the outside of the cabinets to achieve sun protection and rain protection.

[0004] However, when current relay protection systems are located outdoors, their required heat dissipation and rain protection performance vary depending on the season and weather conditions. In other words, current relay protection systems cannot be effectively adjusted according to the needs of different weather seasons. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a microcomputer relay protection device for power detection. It can adjust the folding and opening degree of the two covers according to weather and season, as well as heat dissipation requirements, thereby effectively coping with complex conditions in the actual environment, improving the service life of the electromechanical protection unit, and reducing its failure rate.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: a microcomputer relay protection device for power detection, including a relay protection unit, a support platform, two cover components and a water guide channel. The relay protection unit is connected to the upper side of the support platform, and the two cover components are movably connected to the upper side of the support platform. The two cover components form a cylindrical structure with an opening on the upper side. Each cover component is composed of multiple "L"-shaped rods and flexible cloth connected to each other. The "L"-shaped rods are slidably connected to the support platform along the circumferential direction. The cover components can be folded and retracted. The water guide channel is connected to the upper side of the support platform and blocks the opening position.

[0007] Furthermore, it also includes a funnel-shaped water guide channel, a support pipe connected to the middle of the water guide channel, the support pipe passing through the lower side of the support platform, a water distribution pipe connected to the lower end of the support pipe, and the water distribution pipe located on the lower side of the support platform.

[0008] Furthermore, it also includes multiple first sliding members, a first circular rail, multiple second sliding members, and a second circular rail. The multiple first sliding members correspond one-to-one with the "L"-shaped rod. The first sliding members are fixedly connected to the upper end of the "L"-shaped rod. The first circular rail is connected to the upper end of the water guide channel. The first sliding members slide along the first circular rail via guide wheels. The multiple second sliding members are fixedly connected one-to-one with the lower end of the "L"-shaped rod. The second circular rail is connected to the support platform. The second sliding members slide along the second circular rail via guide wheels.

[0009] Furthermore, it also includes sealing plates and mating grooves. The sealing plates are respectively connected to both sides of the support platform. Each side of the sealing plate has a mating groove, which is engaged and sealed with the corresponding "L"-shaped rod.

[0010] Furthermore, it also includes two motors, two gears, and an arc-shaped rack. The two motors are respectively connected to both sides of the support platform, and the two gears are respectively fixed to the output shafts of the motors. Arc-shaped racks mesh on both sides of the gears, and the arc-shaped racks are connected to corresponding "L"-shaped rods. The arc-shaped racks are slidably connected to the side of the support platform.

[0011] The beneficial effects of this utility model are as follows: By setting the relay protection unit on a support platform and shielding it with two cover components, the cover components replace the traditional small house structure. When fully unfolded, the cover components can achieve good rain and sun protection effects. In scenarios requiring rapid heat dissipation or maintenance operations, the cover components on both sides can be folded. The folding and unfolding of the flexible cloth can be achieved by sliding the "L"-shaped rod. After the cover components are folded, the relay protection unit is fully exposed for maintenance. The degree of folding and unfolding of the two cover components can be adjusted according to the weather and season, as well as the heat dissipation requirements, thereby effectively coping with complex situations in the actual environment, improving the service life of the electromechanical protection unit, and reducing its failure rate.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figures 1-6 As shown, this embodiment provides a microcomputer relay protection device for power detection, including a relay protection unit 1, a support platform 2, two cover components 3, and a water guide channel 6. The relay protection unit 1 is connected to the upper side of the support platform 2, and the two cover components 3 are movably connected to the upper side of the support platform 2. The two cover components 3 form a cylindrical structure with an opening on the upper side. The cover component 3 is composed of multiple "L"-shaped rods 4 and flexible cloth 5 connected to each other. The "L"-shaped rods 4 are slidably connected to the support platform 2 along the circumferential direction. The cover component 3 can be folded and retracted. The water guide channel 6 is connected to the upper side of the support platform 2 and blocks the opening position.

[0021] In the above embodiments, the relay protection unit 1 is mounted on the support platform 2 and shielded by two cover components 3. The cover components 3 replace the traditional small house structure. When the cover components 3 are fully unfolded, they can achieve good rain and sun protection effects. In scenarios requiring rapid heat dissipation or maintenance operations, the cover components 3 on both sides can be folded. The folding and unfolding of the flexible cloth 5 can be achieved by sliding the "L"-shaped rod 4. After the cover components 3 are folded, the relay protection unit 1 is fully exposed for maintenance. The degree of folding and unfolding of the two covers can be adjusted according to the weather and season, as well as the heat dissipation requirements, thereby effectively coping with complex situations in the actual environment, improving the service life of the electromechanical protection unit, and reducing its failure rate.

[0022] Specifically, it also includes a funnel-shaped water guide channel 6, a support pipe 7 connected to the middle of the water guide channel 6, the support pipe 7 passing through the lower side of the support platform 2, and a water distribution pipe 8 connected to the lower end of the support pipe 7, with the water distribution pipe 8 located on the lower side of the support platform 2.

[0023] In the above embodiments, the opening on the upper side of the cover 3 is blocked by the water guide channel 6, thereby achieving a complete sealing effect. Rainwater is guided into the support pipe 7 through the funnel-shaped water guide channel 6 and discharged through the water distribution pipe 8 below the support platform 2.

[0024] Specifically, it also includes multiple first sliding members 9, a first circular rail 10, multiple second sliding members 11, and a second circular rail 12. The multiple first sliding members 9 correspond one-to-one with the "L"-shaped rod 4. The first sliding members 9 are fixedly connected to the upper end of the "L"-shaped rod 4. The first circular rail 10 is connected to the upper end of the water guide trough 6. The first sliding members 9 slide along the first circular rail 10 through guide wheels. The multiple second sliding members 11 are fixedly connected one-to-one with the lower end of the "L"-shaped rod 4. The second circular rail 12 is connected to the support platform 2. The second sliding members 11 slide along the second circular rail 12 through guide wheels.

[0025] In the above embodiments, the stable sliding operation of the "L"-shaped rod 4 is achieved through the first sliding member 9, the second sliding member 11, and other structures.

[0026] Specifically, it also includes a sealing plate 13 and a docking groove 14. The sealing plate 13 is connected to both sides of the support platform 2. The sealing plate 13 has a docking groove 14 on both sides. The docking groove 14 is engaged and sealed with the corresponding "L" shaped rod 4.

[0027] In the above embodiments, the sealing performance of the overall device is further improved by the sealing plate 13, so that the relay protection unit 1 can be fully wrapped and shielded when rain protection is required.

[0028] Specifically, it also includes two motors 15, two gears 16 and an arc-shaped rack 17. The two motors 15 are respectively connected to both sides of the support platform 2, and the two gears 16 are respectively fixed to the output shaft of the motors 15. Arc-shaped racks 17 are meshed on both sides of the gears 16. The arc-shaped racks 17 are connected to the corresponding "L"-shaped rods 4 and are slidably connected to the side of the support platform 2.

[0029] In the above embodiments, the motor 15 drives the gear 16 to rotate, and the gear 16 drives the arc-shaped racks 17 on the upper and lower sides, thereby pulling the "L"-shaped rods 4 on both sides of the cover 3, thus realizing the folding and opening of the cover 3.

[0030] The working principle of this utility model is as follows: The support platform 2 is connected to the ground by bolts or cement casting, so that the water distribution pipe 8 is buried in the stratum. The whole device is controlled by a remote control module (the remote control module can use existing technology, and the operation of the motor 15 can be controlled according to the needs). When rain protection is needed, the motor 15 drives the gear 16 to rotate, the gear 16 drives the two corresponding arc racks 17 to move, and the arc racks 17 push the "L"-shaped rods 4 at both ends of the cover 3, so that the "L"-shaped rods 4 slide, the cover 3 unfolds, and the "L"-shaped rods 4 on both sides are engaged in the docking grooves 14 of the sealing plate 13, realizing the all-round wrapping of the relay protection unit 1. During this process, the "L"-shaped rods 4 achieve stable sliding through the first sliding member 9 and the second sliding member 11 above and below.

[0031] When the weather is hot and heat dissipation or maintenance is required, the running motor 15 causes the cover 3 to fold, exposing the relay protection unit 1, thereby achieving rapid heat dissipation and convenient maintenance.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
