Description

Technical Field

[0001] The invention relates to the technical field of adaptive switch cabinets, in particular to an electric crank of an adaptive switch cabinet. Background Art

[0002] The adaptive switch cabinet electric crank is an electric operating device designed specifically for switch cabinets. The adaptive switch cabinet electric crank converts electrical energy into mechanical energy through the built-in motor and transmission mechanism, thereby driving the trolley or circuit breaker in the switch cabinet to perform the swing-in and swing-out operation. Its adaptive function is mainly reflected in the automatic recognition and adaptation of the swing hole angles of different switch cabinet trolleys. Through intelligent algorithms and sensor technology, the electric crank can automatically adjust its operating angle and strength to ensure accurate docking and stable operation with the switch cabinet trolley. The adaptive switch cabinet electric crank is widely used in switch cabinet equipment in various power systems.

[0003] For example, the Chinese patent "An Electric Crank of a Trolley Switch Cabinet" with publication number CN216904010U includes a first crank and a second crank, the first crank is inserted into the second crank, the first crank is provided with a guide mechanism, the second crank is provided with a limiting mechanism, the guide mechanism is inserted into the limiting mechanism; the second crank is movably arranged in a mounting plate, the second crank is connected to a torque sensor, a power mechanism is arranged in the mounting plate, the power mechanism is connected to the second crank, a display panel is arranged on the mounting plate, the display panel is electrically connected to the torque sensor and the power mechanism, the guide mechanism includes a mounting plate, the mounting plate is fixedly mounted on the first crank, and the first crank is provided with a first guide plate extending along an axial direction perpendicular to the first crank.

[0004] Although the above-mentioned prior art can realize the use of electric cranks, in actual use, on the one hand, the crank handle is difficult to fold and store, and usually the crank handle rotates together when the crank mechanism is working, causing the rotating crank handle to easily hit the operator, thereby posing a threat to the personal safety of the operator. On the other hand, the plug rod is difficult to replace, and switch cabinets of different sizes require the use of plug rods that match them, resulting in the need to replace different crank mechanisms for operation, thereby reducing the adaptability of the crank mechanism. Therefore, it does not meet the existing needs. In this regard, we propose an adaptive switch cabinet electric crank. Summary of the invention

[0005] The object of the present invention is to provide an adaptive switch cabinet electric crank to solve the problems in the above background technology that the crank is difficult to fold and store, and the plug rod is difficult to replace.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electric crank of an adaptive switch cabinet, comprising a base, a mounting rod is arranged on the upper part of one side of the base, one end of the mounting rod passes through and extends to the other side of the base, and the mounting rod is rotatably connected to the base, a rotating plate is fixedly arranged on one end of the mounting rod located on one side of the base, a storage cavity is arranged below the interior of the rotating plate, the storage cavity is an open structure, a fixing rod is arranged inside the storage cavity, the fixing rod is rotatably connected to the inner wall of the storage cavity, a crank is fixedly arranged on the outer part of the fixing rod, and one end of the crank extends to the outside of the rotating plate.

[0007] Preferably, a rotating motor is fixedly provided at the rear end of the exterior of the rotating plate, and the output shaft of the rotating motor extends into the interior of the storage cavity and is fixedly connected to the fixing rod.

[0008] Preferably, a cross-shaped slot is provided inside the mounting rod on the other side of the base, the cross-shaped slot is an open structure, a connecting seat is provided inside the cross-shaped slot, one end of the connecting seat extends to the outside of the cross-shaped slot, and an insertion rod is fixedly provided on one end of the connecting seat located outside the cross-shaped slot.

[0009] Preferably, two threaded holes are provided at the upper and lower ends of the interior of the mounting rod on the other side of the base and inside the connecting seat. The threaded holes on the connecting seat correspond to the positions of the threaded holes on the mounting rod, and the threaded holes are of a through-type structure. A bolt is provided inside the threaded hole at one end of the mounting rod, and the bolt passes through the connecting seat and extends to the threaded hole at the other end of the mounting rod, and the two bolts are installed in opposite directions.

[0010] Preferably, a driving cavity is provided inside the base, and the mounting rod passes through the driving cavity. A rotating rod is provided below the driving cavity, and the rotating rod is rotatably connected to the inner wall of the driving cavity.

[0011] Preferably, the outer sleeve of the rotating rod in the driving cavity is fixedly provided with a driving gear, and the outer portion of the mounting rod in the driving cavity is fixedly provided with a transmission gear, and the transmission gear is meshingly connected with the driving gear.

[0012] Preferably, a driving motor is fixedly disposed below the other side of the base, and an output shaft of the driving motor extends into the driving cavity and is fixedly connected to the rotating rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can fold and store the crank through the rotating motor and the storage cavity. When the crank mechanism is rotated, the base is fixed by using an external tool, and then the insertion rod is inserted into the switch cabinet. At this time, the rotating motor is turned on to make the output shaft of the rotating motor drive the fixed rod to rotate, and the crank is driven to rotate clockwise by the rotation of the fixed rod until the crank is rotated into the storage cavity. At this time, the driving motor is turned on again to operate electrically. When manual operation is required, the rotating motor is turned on again, and the rotating motor drives the fixed rod to drive the crank to rotate counterclockwise until the crank is rotated to a horizontal state. At this time, the operator holds the crank for manual operation, thereby avoiding the situation where the crank accidentally injures the operator during electric operation.

[0014] 2. The present invention can replace plug rods of different sizes through bolts and connecting seats. When operating different switch cabinets, it is necessary to replace them with plug rods that are compatible with them. At this time, the bolts are rotated to move outward from the threaded holes through the external threads until the bolts are disengaged from the mounting rod. At this time, the old plug rod is removed from the mounting rod, and the connecting seat on the new plug rod is aligned with the opening of the cross-shaped slot and inserted into the cross-shaped slot until the plug rod is moved to a suitable position. At this time, the threaded holes on the connecting seat correspond to the positions of the threaded holes on the mounting rod, and the plug rod is fixed to the mounting rod with bolts, thereby improving the adaptability of the rocking mechanism to switch cabinets of different sizes.

[0015] 3. The present invention can provide protection for the driving gear and the transmission gear by providing a driving cavity. The driving gear and the transmission gear are in direct contact with the external environment when working, which causes moisture and dust in the air to easily adhere to the surface of the driving gear and the transmission gear, thereby causing corrosion on the surface of the driving gear and the transmission gear. The provided driving cavity can isolate the driving gear and the transmission gear from the outside world, and lubricating oil can be provided inside the driving cavity, thereby reducing the friction between the driving gear and the transmission gear.
