Description

Technical Field

[0001] The invention belongs to the technical field of substation maintenance, and in particular relates to an adaptive opening and closing device and method. Background Art

[0002] With the rapid development of modern power systems, the application of integrated switchgear in substations has become more and more common. The switchgear used in 10kV to 35kV power distribution systems is equipped with primary circuits or circuit breakers for transmitting high-voltage lines. When there is a fault in the primary circuit and the opening and closing switch operation is required, it may cause a fire or explosion in the line, which may threaten the personal safety of the operator in serious cases. At present, there are devices based on remote control to operate the opening and closing switches. However, due to the different sizes of the opening and closing switch buttons in the station, the existing remote control device can only operate individual opening and closing switches that match the device, which has certain limitations.

[0003] The prior art discloses a mechanical arm end operation work (CN115446868A) that integrates pressing and twisting. When the twisting function is used, the mechanical arm advances to a certain position according to the distance between the driving handle 11 and the operating object, causing the low-rigidity spring 13 to be compressed, that is, the driving handle 11 is connected to the operating object, and then the steering gear is started and starts to rotate. While rotating, under the action of the elastic force of the low-rigidity spring 13, when the driving handle 11 and the operating object are just aligned, the driving handle 11 automatically inserts into the operating object hole and starts the twisting operation. However, the shortcoming of the prior art is that it cannot adapt to the rotation of any size knob, and can only be used for the opening and closing operation of the 10kV switch cabinet of a conventional substation, and does not have the value of wide application and promotion.

[0004] To solve the above problems, it is necessary to improve the existing remote control opening and closing device so that it can operate the opening and closing switches of all switch cabinets in the substation, further ensuring the life safety of the operators. Summary of the invention

The steel column-spring switch head 17 includes a spring module 10, a cylindrical steel pipe module 11, a steel bracket structure 15 and a cylindrical groove 16. The cylindrical groove 16 is a U-shaped structure. The outer side of the bottom of the U-shaped structure is fixedly connected to the rotating unit. The spring module 10 and the steel bracket structure 15 are arranged inside the cylindrical groove 16. The cylindrical groove 16 is used to limit the deformation of the spring module 10 so that it can only be pulled in a specified direction. One end of the spring module 10 is fixedly connected to the bottom surface of the inner side of the U-shaped structure of the columnar groove 16, and the other end is fixedly connected to the columnar steel pipe module 11. A steel bracket structure 15 is fixedly arranged on the inner side of the opening of the U-shaped structure of the columnar groove 16, which is tightly fitted with the columnar steel pipe module 11 and is used to limit the activity of the columnar steel pipe module 11. In the natural state, a part of the columnar steel pipe module 11 is located inside the columnar groove 16. When the external pressure is applied, the columnar steel pipe module 11 squeezes the spring module 10, and more parts enter the columnar groove 16. Figure 3 and Figure 4 As shown, it is a schematic diagram of a single set of steel column-spring switch head 17 in a natural state and a squeeze spring module 10 in a state.

[0058] The power supply unit includes a device power switch 5, a charging port 6 and a battery pack 7. The power switch 5 is arranged on the top surface of the shell near the tail end, and is used to control whether the power supply unit is discharged. The charging port 6 is arranged on the outer surface of the tail end of the shell and is electrically connected to the battery pack 7. The battery pack 7 is fixedly arranged at the tail end inside the shell.

[0059] The camera unit includes a fill light illumination switch 2, a fill light illumination 3 and a camera module 4. The fill light illumination switch 2 is used to control the switch of the fill light illumination 3. There are two fill light illuminations 3, which are symmetrically arranged on the upper and lower sides of the fill light illumination switch 2. The camera module 4 is arranged at the bottom of the camera unit. The camera unit is powered by a power supply unit. The fill light illumination 3 is used to provide lighting for the camera module in the device when the light is dim. The camera module 4 is used to record the entire working process during operation and upload it to the background in real time, as well as observe the changes of other signal lights on the switch cabinet.

[0060] The proximal opening and closing device of the adaptive opening and closing device provided in the embodiment of the present invention also includes a servo motor 8 and a device reset button 9. The servo motor 8 is connected between the power supply unit and the rotating unit. The servo motor 8 is used to drive the opening and closing operating unit to rotate to realize the opening and closing operation. The servo motor 8 is electrically connected to the power supply unit, and the power supply unit is used to supply energy to the servo motor 8. The device reset button 9 is arranged on the side of the shell and is electrically connected to the power supply unit. The device reset button is used to reset the adaptive opening and closing device.

[0061] The models and sizes of the switch cabinet opening and closing operation buttons in the substation are diverse.

When the opening and closing operation is not required, the spring is extended, and all the steel columns in the device remain in contact with the outermost plane of the device; when the opening and closing operation is required, the device of the present invention is tightly attached to the opening and closing button of the switch cabinet through the magnetic attraction effect. Since the opening and closing button has a certain hardness, the steel column of the present invention attached to the opening and closing button can be compressed into the inside of the device together with the spring, while the part of the steel column that is not in contact with the opening and closing button is not compressed, thereby ensuring that the device of the present invention is completely in contact with the opening and closing button; finally, the servo motor inside the present invention is used to drive the steel column to rotate to achieve the opening and closing operation.

[0062] Embodiment 2

[0063] Embodiment 2 of the present invention provides an adaptive opening and closing method. Figure 2 ~Attached Figure 5 The present invention is used to describe the method for implementing the opening and closing operation, including:

[0064] Step 1: The adaptive opening and closing device is adsorbed on the surface of the opening and closing button of the switch cabinet by a magnetic fixing belt. At this time, the opening and closing button is completely inserted into the device, and the opening and closing operation unit compresses the device and its corresponding cylindrical steel pipe module into the device through the spring module;

[0065] Step 2, the servo motor inside the device is controlled to rotate by the remote control device, and the rotation of the servo motor drives the cylindrical steel pipe module to rotate, and then the switch cabinet opening and closing buttons follow the rotation, thereby realizing the opening and closing operation;

[0066] The outstanding feature of the present invention is that the spring-steel column type opening and closing operating mechanism designed by the present invention can adapt to opening and closing buttons of any size, so that the device has a wider range of applications and has great application value.

[0067] Embodiment 3

[0068] Embodiment 3 of the present invention provides a support structure suitable for enhancing the physical stability of the adaptive opening and closing device during operation. Figure 7As shown, the support structure 14 is installed on the bottom surface near the rear end of the housing, and the support structure 14 includes an annular sleeve 19 and a retractable support 18. The retractable support 18 is arranged on the annular sleeve 19, and the annular sleeve 19 is sleeved on the housing of the proximal opening and closing device. The support structure 14 is used to support the rear end of the proximal opening and closing device, and cooperates with the magnetic fixing belt 12 to prevent the opening and closing device from falling or instability during operation, thereby improving its working stability. In a preferred but non-limiting embodiment of the present invention, the number of retractable supports 18 is 3. The annular sleeve can be sleeved on the opening and closing device, and the retractable support can retract the length of the support, which is simple and convenient.

[0069] The adaptive opening and closing device in the present invention is adsorbed on the switch cabinet by magnetic attraction, but the weight of the opening and closing device itself can easily cause it to fall during the adsorption process. The present invention provides a bracket structure adapted to the opening and closing device, through which the force point of the opening and closing device can be changed during operation to ensure the stability of the device.

[0070] Embodiment 4

[0071] Embodiment 4 of the present invention provides a method for using a support structure suitable for enhancing the physical stability of an adaptive opening and closing device during operation, comprising:

[0072] Step 1, see attached Figure 6 As shown, when the adaptive opening and closing device needs to work, the annular sleeve of the bracket structure is sleeved on the side of the near-end opening and closing device close to the switch cabinet;

[0073] Step 2, open the retractable bracket of the bracket structure, and use it to support the power supply side of the proximal opening and closing device, that is, the bottom end of the side away from the switch cabinet, to complete the support of the bracket structure. This can prevent the proximal opening and closing device from falling or becoming unstable during operation. By using this bracket structure, the force points of various parts of the adaptive opening and closing device can be changed during operation, thereby improving its working stability.

[0074] Embodiment 5

[0075] Embodiment 5 of the present invention provides a portable emergency safety opening and closing method, including:

[0076] Step 1: Put the annular sleeve on the side of the near-end opening and closing device close to the switch cabinet, open the retractable bracket to support the other side of the near-end opening and closing device, and press the device reset button;
