A primary and secondary fusion ring network cabinet and a use method thereof

Abstract

This application provides a primary and secondary integrated ring main unit, including a cabinet body. Heat dissipation vents are provided on both side walls of the cabinet body, and each vent is fixedly connected to a mounting frame. Each mounting frame contains a swing-type heat dissipation structure. By setting the swing-type heat dissipation structure, air cooling is achieved through swinging motion within the cabinet body, efficiently dissipating heat outwards. By setting baffles, linkage structures, and heat dissipation structures, the heat dissipation vents can be sealed during rainy weather, preventing rainwater from entering the cabinet body. After sealing, the rainwater is used to dissipate heat from the cabinet body, solving the problem of rainwater easily entering the cabinet body through the heat dissipation vents in existing technologies. By setting connecting frames, a base plate, a fixing plate, threaded rods, moving strips, guide rods, a first connector, an adjusting rod, and a second connector, the cabinet body can be automatically raised during rainy weather. The raised height is relatively high, effectively preventing rainwater from entering from the bottom of the cabinet body, improving the waterproof effect.

Description

Technical Field

[0001] This invention relates to the field of integrated primary and secondary ring main units, and more specifically, to an integrated primary and secondary ring main unit and its usage method. Background Technology

[0002] A ring main unit (RMU) is a set of electrical transmission and distribution equipment, installed in a metal or non-metal insulated cabinet or assembled into a modular ring network power supply unit. Its core components utilize load switches and fuses, offering advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in substations at load centers in urban residential areas, high-rise buildings, large public buildings, factories, and in prefabricated substations, as well as in rural outdoor areas.

[0003] A search revealed that Chinese patent application number CN202123400941.9 discloses "a primary and secondary integrated ring main unit," but it still has the following defects:

[0004] (1) The existing primary and secondary integrated ring main unit dissipates heat through natural heat dissipation. The heat inside the cabinet is not easy to dissipate outwards, and rainwater can easily enter the cabinet through the heat dissipation vents on rainy days.

[0005] (2) In the existing technology, the primary and secondary integrated ring main unit is waterproofed at the bottom by a protective base. The waterproofing effect is not good. When the rainwater accumulation depth is high, rainwater can still easily enter from the bottom.

[0020] This invention also provides a method for using a primary and secondary integrated ring main unit, comprising the following steps:

[0021] S1: When the primary and secondary integrated ring main unit needs heat dissipation during operation, the dual-axis motor is started. The dual-axis motor drives the fan blades to blow air into the cabinet. The other end of the dual-axis motor drives the worm gear to rotate. The worm gear drives the worm wheel, the first rotating rod and the first gear to rotate. The rotation of the first gear drives the second gear, the second rotating rod and the connecting block to rotate, which in turn drives the swing rod to move. This causes the fixed plate, the rotating shaft and the assembly frame to rotate, thereby swinging and blowing air into the cabinet to efficiently dissipate heat from the cabinet.

[0022] S2: When it rains outside, the rain sensor detects rainwater and transmits the signal to the controller. The controller controls the servo motor to work, the servo motor drives the second bevel gear to rotate, the second bevel gear drives the two first bevel gears to rotate synchronously, the rotation of the first bevel gear drives the threaded rod to rotate, the rotation of the threaded rod causes the moving bar to move outward synchronously, thereby moving the adjusting rod and raising the cabinet to prevent rainwater from entering from the bottom.

[0023] S3: In step two, the rotation of the threaded rod drives the connecting shaft and the third bevel gear to rotate. The rotation of the third bevel gear drives the fourth bevel gear, the first connecting shaft, and the fifth bevel gear to rotate. The fifth bevel gear drives the sixth bevel gear and the second connecting shaft to rotate. The rotation of the second connecting shaft drives the first pulley to rotate. The first pulley drives the second pulley to rotate via a belt. The second pulley drives the actuating shaft to rotate. The actuating shaft drives the actuating gear to rotate, thereby causing the rack and baffle to descend, thus sealing the mounting frame and preventing water from entering during rain.

[0024] S4: Rainwater falls into the collection box and collects. The rainwater then enters the cooling pipe and flows through it, carrying away the heat from the cabinet and effectively cooling it. When the rain sensor detects that the rain has stopped, the timer module sets an interval. When the set time is reached, the controller controls the servo motor to reverse, causing the cabinet to descend and reset, while the baffle rises and opens.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In the scheme of this application:

[0027] 1. By setting up a swing-type heat dissipation structure, the swing-type air cooling is realized, which efficiently dissipates the heat inside the cabinet to the outside, solving the problem of heat accumulation and difficulty in dissipation in the existing technology.

[0028] 2. By setting up baffles, linkage structures and heat dissipation structures, the heat dissipation vents can be blocked in rainy weather to prevent rainwater from entering the cabinet. After blocking, the rainwater is used to dissipate heat from the cabinet, which solves the problem that rainwater can easily enter the cabinet through the heat dissipation vents in the existing technology.

[0029] 3. By using a connecting frame, base plate, fixed plate, threaded rod, moving bar, guide rod, first connector, adjusting rod, and second connector, the cabinet can be automatically raised on rainy days. The raised height is relatively high, effectively preventing rainwater from entering from the bottom of the cabinet and improving the waterproof effect. When it is not raining, it is convenient for operators to operate, thus solving the problem of poor waterproof effect at the bottom of the cabinet in the existing technology.

To prevent rainwater from entering from the bottom, the rotation of the threaded rod 8 drives the connecting shaft 1501 and the third bevel gear 1502 to rotate. The rotation of the third bevel gear 1502 drives the fourth bevel gear 1505, the first connecting shaft 1504, and the fifth bevel gear 1506 to rotate. The fifth bevel gear 1506 drives the sixth bevel gear 1509 and the second connecting shaft 1508 to rotate. The rotation of the second connecting shaft 1508 drives the first pulley 1510 to rotate. The first pulley 1510 drives the second pulley 1514 to rotate via the belt 1515. The second pulley 1514 drives the actuating shaft 1512 to rotate. 1512 drives the actuating gear 1513 to rotate, thereby causing the rack 1511 and baffle 4 to descend, thus sealing the mounting frame 2 and preventing water from entering during rain. Rainwater falls into the collection box 1601 and accumulates. The rainwater then enters the cooling pipe 1606, where it flows and carries away the heat from the cabinet 1, effectively cooling it. When the rain sensor 1608 detects that the rain has stopped, the timer module 1609 sets an interval. After the set time is reached, the controller 1610 controls the servo motor 1403 to reverse, causing the cabinet 1 to descend and reset, while the baffle 4 rises and opens.

8. The method of using a primary and secondary integrated ring main unit according to claim 4, characterized in that, Includes the following steps: S1: When the primary and secondary integrated ring main unit needs to dissipate heat during operation, the dual-axis motor (305) is started. The dual-axis motor (305) drives the fan blade (306) to work, thereby blowing air into the cabinet (1). The other end of the dual-axis motor (305) drives the worm gear (307) to rotate. The worm gear (307) drives the worm wheel (3010), the first rotating rod (309) and the first gear (3011) to rotate. The rotation of the first gear (3011) drives the second gear (3014), the second rotating rod (3013) and the connecting block (3015) to rotate, thereby driving the swing rod (3016) to move, thereby causing the fixed plate (3017), the rotating shaft (303) and the assembly frame (304) to rotate, thereby swinging and blowing air into the cabinet (1), efficiently dissipating heat inside the cabinet (1); S2: When it rains outside, the rain sensor (1608) detects rainwater and transmits the signal to the controller (1610). The controller (1610) controls the servo motor (1403) to work. The servo motor (1403) drives the second bevel gear (1404) to rotate. The second bevel gear (1404) drives the two first bevel gears (1401) to rotate synchronously. The rotation of the first bevel gear (1401) drives the threaded rod (8) to rotate. The rotation of the threaded rod (8) causes the moving bar (9) to move outward synchronously, thereby causing the adjusting rod (12) to move, thereby raising the cabinet (1) and preventing rainwater from entering from the bottom. S3: In step two, the rotation of the threaded rod (8) drives the connecting shaft (1501) and the third bevel gear (1502) to rotate. The rotation of the third bevel gear (1502) drives the fourth bevel gear (1505), the first connecting shaft (1504) and the fifth bevel gear (1506) to rotate. The fifth bevel gear (1506) drives the sixth bevel gear (1509) and the second connecting shaft (1508) to rotate. The rotation of the second connecting shaft (1508) drives the first pulley (1510) to rotate. The first pulley (1510) drives the second pulley (1514) to rotate through the belt (1515). The second pulley (1514) drives the actuating shaft (1512) to rotate. The actuating shaft (1512) drives the actuating gear (1513) to rotate, thereby causing the rack (1511) and the baffle (4) to descend, thereby sealing the mounting frame (2) and preventing water from entering when it rains. S4: Rainwater falls into the collection box (1601) and accumulates. The rainwater enters the cooling pipe (1606). The rainwater flows in the cooling pipe (1606) and carries away the heat of the cabinet (1), thereby effectively cooling it. When the rain sensor (1608) detects that the rain has stopped, the timer module (1609) sets the interval time. After the set time is reached, the controller (1610) controls the servo motor (1403) to reverse, so that the cabinet (1) descends and resets. At the same time, the baffle (4) rises and opens.
