[0001] This utility model relates to the field of high-voltage ring main unit technology, specifically to a high-voltage ring main unit door drive mechanism. Background Technology
[0002] High-voltage ring main units are used in substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories. High-voltage ring main units are designed to improve power supply reliability and allow users to obtain power from two directions. They typically connect the power grid into a ring, and this power supply method is simply called ring network power supply. In AC 10KV power distribution systems in ports and high-rise buildings, where the load capacity is not large, the high-voltage circuit is usually controlled by load switches or vacuum contactors and is equipped with high-voltage fuses for protection.
[0003] The existing high-voltage ring main unit has a cabinet door that is hinged on by a door lock to fix the closed cabinet door, but there is no drive mechanism to drive the cabinet door to open and close. Therefore, a high-voltage ring main unit cabinet door drive mechanism is proposed. The drive motor drives the lead screw to rotate, and pushes the connecting telescopic assembly composed of the plate sleeve and the connecting plate to move through the internal threaded slider, thereby driving the cabinet door to open and close through the fixed assembly.

A second structural plate is welded to the top of one end of the side plate, and the second structural plate is rotatably connected to the inside of the second structural seat through a shaft.
[0010] Specifically, the output shaft on one side of the drive motor is fixedly connected to one end of the lead screw via a connecting sleeve, and an auxiliary rod is fixed inside the rectangular housing on one side of the lead screw by bolts. The auxiliary rod passes through the internal threaded slider.
[0011] Specifically, a reserved groove is provided on one side of the rectangular shell, and rubber sealing strips are glued to the top and bottom of the reserved groove.
[0012] Specifically, mounting blocks are welded at equal intervals to the top of the side of the rectangular shell away from the reserved groove.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] The drive motor drives the lead screw to rotate, which in turn pushes the connecting telescopic assembly consisting of the sleeve and connecting plate to move via the internal threaded slider. This, in turn, drives the cabinet door to open and close via the fixed assembly. Figure 1-4 As shown, the high-voltage ring main unit door drive mechanism of this utility model includes a rectangular housing 1. A drive motor 5 is mounted on one end of the rectangular housing 1 through a mounting bracket. A lead screw 4 is rotatably connected inside the rectangular housing 1 through a bearing. An internal threaded slider 6 is sleeved on the outside of the lead screw 4. A first structural plate 7 is fixed to one side of the internal threaded slider 6 by bolts.
[0024] The first structural plate 7 is provided with a connecting telescopic component 2 at one end. The connecting telescopic component 2 includes a plate sleeve 201. A connecting plate 202 is sleeved on one end of the plate sleeve 201. A fixing component 3 is provided on one end of the connecting plate 202.
[0025] In use, the drive motor 5 drives the lead screw 4 to rotate and push the internal thread slider 6 and the first structural plate 7 on one side to move. The first structural plate 7 drives the fixed component 3 and the cabinet door to rotate through the connecting telescopic assembly 2 composed of the plate sleeve 201 and the connecting plate 202, so as to open and close the cabinet door.
[0026] For example, such as Figure 3 As shown, the present invention also includes a first structural seat 203 provided at one end of the plate sleeve 201, the first structural seat 203 being rotatably connected to one end of the first structural plate 7 via a shaft, a fixing bolt 205 being connected to the top of the plate sleeve 201 via a threaded groove, and a locking hole 206 being provided at equal intervals on the top of the connecting plate 202.
[0027] In use, the first structural base 203 is rotatably connected to one end of the first structural plate 7 via a shaft, allowing the plate sleeve 201 to rotate. Tightening the fixing bolt 205 allows its bottom end to be inserted into the corresponding clip hole 206, which can fix the telescopic connecting plate 202.
[0028] For example, such as Figure 3, Figure 4 As shown, the present invention also includes a second structural base 204 provided at one end of the connecting plate 202, and the fixing component 3 includes a side plate 301. A second structural plate 302 is welded to the top end of one end of the side plate 301. The second structural plate 302 is rotatably connected to the inside of the second structural base 204 through a shaft.
[0029] In use, the second structural plate 302 is rotatably connected to the second structural base 204, allowing the second structural plate 302 to rotate.
[0030] For example, such as Figure 2 As shown, this utility model also includes a drive motor 5 with one output shaft fixedly connected to one end of a lead screw 4 via a connecting sleeve, and an auxiliary rod 11 fixed inside the rectangular housing 1 on one side of the lead screw 4 by bolts, the auxiliary rod 11 passing through the internal threaded slider 6.
[0031] In use, the drive motor 5 drives the lead screw 4 to rotate, and the auxiliary rod 11 can prevent the internal thread slider 6 from rotating with the lead screw 4 without affecting its movement.
[0032] For example, such as Figure 2 As shown, the present invention also includes a reserved groove 8 on one side of the rectangular shell 1, and rubber sealing strips 9 are glued to the top and bottom of the reserved groove 8.
[0033] During use, the reserved groove 8 facilitates the movement of the first structural plate 7, and the rubber sealing strip 9 is used to seal the reserved groove 8.
[0034] For example, such as Figure 1 As shown, the present invention also includes mounting blocks 10 welded at equal intervals to the top of the reserved groove 8 on one side of the rectangular shell 1 away from the pre-reserved groove 8.
[0035] When in use, the mounting block 10 is designed to allow personnel to use bolts to fix the rectangular housing 1 inside the high-voltage ring main unit.
[0036] In use, personnel use bolts to fix the rectangular shell 1 to the inside of the high-voltage ring main unit via the mounting block 10, use bolts to fix the second structural plate 302 to the door of the high-voltage ring main unit, and use a power cord to connect the device to an external power source.
[0037] The drive motor 5 is controlled by an external device. The drive motor 5 drives the lead screw 4 to rotate and push the internal thread slider 6 and the first structural plate 7 on one side to move. The movement of the first structural plate 7 drives the second structural plate 302 and the cabinet door to rotate through the plate sleeve 201 and the connecting plate 202, thereby realizing the opening and closing of the cabinet door.
[0038] One end of the sleeve 201 is rotatably connected to one end of the first structural plate 7 via a shaft, and one end of the connecting plate 202 is rotatably connected to the second structural seat 204 at one end of the connecting plate 202 via a shaft, so that the sleeve 201 and the connecting plate 202 can rotate. The connecting plate 202 is sleeved on one end of the sleeve 201, so that it can extend and retract, providing the space required for the cabinet door to rotate and open and close.
