[0002] In substations, power plants, and other electrical scenarios, it is often necessary to switch circuits based on circuit status or other unforeseen circumstances, such as main / backup power switching, maintenance and repair, and fault occurrences. Currently, switching circuits typically requires on-site workers to monitor the circuit status. When a circuit switch is needed, workers must manually operate the switches one by one at each piece of equipment, which is manpower-intensive, slow, and inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide a remotely controllable electrical distribution switching device to solve the technical problems in the prior art that require workers to be stationed at each site to monitor the circuit status and workers to manually switch the power distribution.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0005] A remotely controllable electrical power distribution switching device includes a display control box installed at a remote control terminal, and a switch mechanism and a monitoring camera respectively installed at the site of the power switch and electrically connected to the display control box. The display control box is installed at the remote control terminal, and the number of the switch mechanism and the number of the monitoring camera correspond one-to-one with the number of power switches.

[0006] Each lever mechanism is arranged adjacent to each power switch and includes a drive motor, a lever block, and a slot. The drive motor is located outside the swing direction of the power switch and its power output end is connected to the power input end of the lever block. The slot is located at the power output end of the lever block, with its opening facing the power switch and on the same horizontal plane as the power switch. The width of the slot is greater than the width of the power switch. The lever block has the freedom to drive the power switch to perform a levering action under the drive of the drive motor.

[0007] The surveillance camera is pointed at the corresponding tripping mechanism and power switch.

[0008] The display control box is equipped with a display screen and control buttons. The monitoring camera is connected to the display screen via a signal. The control buttons correspond one-to-one with the switch mechanism and are electrically connected to the switch mechanism.

[0009] The drive motor is also equipped with a signal receiving and conversion module, and the control button is electrically connected to the drive motor through the signal receiving and conversion module.

[0010] Both the power switch and the lever mechanism are mounted on the outer casing. The lever mechanism also includes a sliding part, the extension direction of which is the same as the extension direction of the swing shaft of the power switch. The drive motor is mounted on the sliding part and has the freedom to drive the slot to engage or disengage from the power switch along the extension direction of the sliding part.

[0011] The sliding part includes a sliding groove, a sliding block and a baffle. The sliding groove is disposed on the outer casing, and the sliding block is disposed in the sliding groove and has the freedom to slide along the sliding groove.

[0012] The side wall of the outer casing is provided with a limiting groove that communicates with the slide groove and is perpendicular to the extension direction of the slide groove. The baffle is inserted into the slide groove through the limiting groove. The distance between the limiting groove and the end of the slide groove near the power switch is the same as the length of the sliding block.

[0013] When the sliding block is located at one end of the slide groove near the power switch, the slot is engaged with the power switch; when the sliding block is located at one end away from the power switch, the slot is completely disengaged from the power switch.

[0014] The outer casing is also equipped with an audible and visual alarm mechanism, which is electrically connected to the display control box.

[0015] The audible and visual alarm mechanism includes an alarm light and a buzzer, which are electrically connected to the display control box.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a remotely controllable electrical distribution switching device. By setting up a switching mechanism, a monitoring camera, and a display control box, the monitoring camera monitors the status of each power switch, and the information is displayed to the staff in real time on the display screen on the control box. The staff can automatically switch the power switches by pressing the corresponding control buttons according to the monitoring information on the display screen, which is convenient and quick. It eliminates the need to arrange multiple staff members to monitor the circuit status and switch the switches on-site. Only a small number of staff members or even just one staff member are needed to monitor the display screen, greatly reducing the workload of staff.

[0017] In addition, in case of any abnormal situation and the switch cannot be switched normally, the operator can slide the sliding block away from the power switch to disengage the power switch from the slot, and then manually switch it. The manual / automatic switching of the switching device is convenient and facilitates the handling of abnormal situations.

[0022] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides a remotely controllable electrical power distribution switching device, which includes a display control box set at the remote control terminal, and a toggle mechanism and a monitoring camera 8 respectively set at the site of the power switch 2 and electrically connected to the display control box. The number of monitoring cameras 8 and power switches 2 can be one-to-one or one-to-many. In this embodiment, since the power switches 2 are relatively dispersed, in order to clearly monitor the status of the power switches 2, the number of toggle mechanisms and monitoring cameras 8 are respectively one-to-one with the number of power switches 2. The monitoring camera 8 points to the corresponding toggle mechanism and power switch 2. The monitoring camera 8 monitors the circuit status at the site and displays it to the staff through the display control box. The display control box controls the toggle mechanism to act, thereby driving the power switch 2 to switch the power distribution.

[0024] Specifically, such as Figure 2As shown, the power switch 2 and the lever mechanism are both mounted on the outer casing 3. Each lever mechanism is arranged adjacent to each power switch 2 and includes a drive motor 5, a lever block 6, and a slot 7. The drive motor 5 is located outside the swing direction of the power switch 2, and its power output end is connected to the power input end of the lever block 6. By controlling the drive motor 5 to swing at a corresponding angle, the power switch 2, which is locked in the slot 7 of the lever block 6, is driven to perform a lever action. To achieve this function, the slot 7 is located at the power output end of the lever block 6. The opening of the slot 7 faces the power switch 2 and is on the same horizontal plane as the power switch 2. The width of the slot 7 is greater than the width of the power switch 2. The lever block 6 has the freedom to swing under the drive of the drive motor 5 to drive the power switch 2 to perform a lever action.

[0025] Furthermore, to facilitate remote observation and control by staff, the display control box in this embodiment is equipped with a display screen 9 and control buttons 10. The monitoring camera 8 is signal-connected to the display screen 9, and the control buttons 10 correspond one-to-one with the switch mechanism and are electrically connected to the switch mechanism.

[0026] Meanwhile, in order to convert the action command issued by the control button 10 into the action signal of the drive motor 5, the drive motor 5 is also provided with a signal receiving and conversion module 11 for receiving the signal issued by the control button 10 and controlling the action of the drive motor 5. The control button 10 is electrically connected to the drive motor 5 through the signal receiving and conversion module 11.

[0027] Furthermore, in order to enable manual operation when the tripping mechanism fails to operate normally in an abnormal situation, the tripping mechanism in this embodiment also includes a sliding part, wherein the sliding part includes a sliding groove 13, a sliding block 4 and a baffle 12. The sliding groove 13 is disposed on the outer casing 3, the sliding block 4 is embedded in the sliding groove 13 and has the degree of freedom to slide relative to the sliding groove 13, and the drive motor 5 is disposed on the sliding block 4 and has the degree of freedom to drive the slot 7 to engage or disengage from the power switch 2 along the extension direction of the sliding groove 13 under the drive of the sliding block 4. To limit the sliding block 4 when the lever block 6 engages the power switch 2, preventing it from sliding freely and causing the lever block 6 to disengage from the power switch 2, in this embodiment, the side wall of the outer casing 3 has a limiting groove that communicates with the slide groove 13 and is perpendicular to the extension direction of the slide groove 13. The baffle 12 is inserted into the slide groove 13 through the limiting groove. The distance between the limiting groove and the end of the slide groove 13 closest to the power switch 2 is the same as the length of the sliding block 4. The baffle 12 can limit the sliding block 4, thereby ensuring stable operation. In this embodiment, the length of the slide groove 13 should be greater than the depth of the locking groove 7, so that when the sliding block 4 is located at the end of the slide groove 13 closest to the power switch 2, the locking groove 7 engages the power switch 2; when the sliding block 4 is located at the end furthest from the power switch 2, the locking groove 7 completely disengages from the power switch 2.

[0028] Furthermore, in order to issue an alarm when the circuit is abnormal, the outer casing 3 in this embodiment is also equipped with an audible and visual alarm mechanism, which specifically includes an alarm light 14 and a buzzer 15. The alarm light 14 and the buzzer 15 are electrically connected to the display control box, respectively, and emit flashing and sound reminders when a circuit abnormality occurs, thereby reminding the staff to switch the circuit in time.
