Description

Technical Field

[0001] The utility model relates to the technical field of electric operating tools, in particular to an operating rod. Background Art

[0002] High-voltage insulated operating rods are indispensable tools in the power industry, primarily used to operate pole-mounted switchgear, disconnectors, and drop-out switches in distribution networks while energized. These devices are typically installed at heights of up to 10 meters or more above the ground. Operators must use multiple sections of high-voltage insulated operating rods to extend their lengths and reach the elevated equipment. However, due to their slender structure and low rigidity, high-voltage insulated operating rods are susceptible to vibration caused by gravity and operating forces. This can make it difficult to align the operating rod with the operating hole of the target device, or it can slip from the device structure during operation, leading to misoperation or complete inability to operate, severely impacting operational efficiency and safety.

[0003] The design of traditional high-voltage insulated operating rods lacks adequate consideration for maintaining stability during operation. This can exacerbate the rod's vibration, especially in the presence of wind or the operator's slightest movement, making operation more difficult. Furthermore, because the length of the high-voltage insulated operating rod is adjustable, the joints between the multiple sections can become unstable, further reducing operational accuracy and safety. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems in the prior art. To this end, the present invention provides an operating rod that can improve the stability of operation, reduce vibration and improve the accuracy of operation.

[0005] According to a first embodiment of the present invention, an operating lever includes:

[0006] The rod assembly includes an armrest portion provided at the head end of the rod assembly, an operating portion provided at the tail end of the rod assembly, and a hollow installation cavity provided on the inner side of the rod assembly;

[0007] A stabilizing assembly is provided at the end of the mounting cavity, the stabilizing assembly is provided corresponding to the operating portion, the stabilizing assembly includes an inertia flywheel assembly and a drive motor, and the drive motor is transmission-connected to the inertia flywheel assembly;

[0008] a trigger assembly, disposed at the head end of the mounting cavity, the trigger assembly being disposed corresponding to the armrest portion, the trigger assembly comprising a trigger button, and the trigger button being electrically connected to the drive motor;

[0009] The trigger button is used to control the driving motor to rotate or stop, thereby controlling the rotation state of the inertia flywheel assembly.

[0010] An operating lever according to an embodiment of the present utility model has at least the following beneficial effects: by arranging a stabilizing assembly consisting of an inertial flywheel group and a drive motor inside the operating lever, the stabilizing torque generated by the high-speed rotating inertial flywheel can be used to effectively offset the vibration of the operating lever caused by its own gravity and operating force when the operating part of the operating lever is working, thereby significantly improving the accuracy and stability of the operation; the introduction of the trigger assembly enables the operator to conveniently remotely control the start and stop of the drive motor through the trigger button, thereby controlling the rotation state of the inertial flywheel group, realizing instant activation or shutdown of the stabilizing assembly, and enhancing the flexibility and response speed of the operation; because the inertial stabilizing device can significantly reduce the vibration of the operating lever, the risk of slipping or mispositioning with the target equipment during operation is reduced, thereby improving the safety of operation and reducing the potential dangers in power maintenance and repair work; the combination of the trigger assembly and the stabilizing assembly enables the operating lever to adapt to different operating environments and work requirements, and the operator can adjust the working state of the stabilizing assembly at any time according to actual conditions, thereby improving the versatility and applicability of the equipment.

[0011] According to some embodiments of the present invention, a coupling is provided between the inertial flywheel assembly and the drive motor. The coupling is a permanent magnet coupling. The characteristics of a permanent magnet coupling allow for more precise control of the inertial flywheel assembly's rotational state, ensuring smooth transitions when the motor starts and stops, avoiding shocks caused by sudden acceleration or deceleration, and further improving operational stability and accuracy.

[0012] According to some embodiments of the present invention, the rod assembly further includes a replaceable operating head connected to the operating portion via a slot. The quick-change mechanism of the operating head saves time in preparing and switching tools, allowing operators to quickly respond to different operating tasks on site without having to carry multiple specialized tools, significantly improving work efficiency.

[0013] According to some embodiments of the present invention, the rod assembly is composed of a plurality of telescopic round tubes connected end to end. The connection method of the telescopic round tubes is generally relatively simple, and the operator can quickly adjust the length of the operating rod without complicated assembly steps, thereby improving work efficiency.

[0014] According to some embodiments of the present invention, the rod assembly includes a plurality of connecting rods, each of which has a threaded connection at its head and tail, and the plurality of connecting rods are connected via the threaded connection. The threaded connection provides a reliable mechanical connection method, ensuring the tightness and stability of the connection. Even when subjected to large torques during operation, the connection remains secure, avoiding operational failures or safety accidents caused by unstable connections.

[0015] According to some embodiments of the present utility model, the drive motor is a DC motor. The start-up and stop response times of a DC motor are short, and it can quickly reach the required rotational speed, which is very beneficial for high-voltage operation scenarios that require quick response.

[0016] According to some embodiments of the present utility model, the rod body assembly is made of insulating material. An operating rod made of insulating material can be safely used on various electrical devices. Whether it is an outdoor power line or an indoor power distribution cabinet, it can provide necessary electrical isolation.

[0030] Referring to Figures 1 to 3 , an operating lever, comprising:

[0031] A rod body assembly 110, including an armrest portion 100 provided at the head end of the rod body assembly 110, an operating portion is provided at the end of the rod body assembly 110, and a hollow installation cavity is provided inside the rod body assembly 110;

[0032] A stabilizing assembly, provided at the end of the installation cavity, the stabilizing assembly is provided corresponding to the operating portion, and the stabilizing assembly includes an inertia flywheel group 140 and a driving motor, and the driving motor is in transmission connection with the inertia flywheel group 140;

[0033] A triggering assembly, provided at the head end of the installation cavity, the triggering assembly is provided corresponding to the armrest portion 100, and the triggering assembly includes a triggering button, and the triggering button is electrically connected to the driving motor;

[0034] Wherein, the triggering button is used to control the rotation or stop of the driving motor, and further control the rotation state of the inertia flywheel group 140.

[0035] By setting up a stabilization assembly composed of an inertial flywheel group 140 and a drive motor inside the joystick, when the operating part of the joystick is working, the stabilizing torque generated by the high-speed rotating inertial flywheel can effectively offset the flutter of the joystick caused by its own gravity and operating force, significantly improving the accuracy and stability of the operation; the introduction of the trigger assembly enables the operator to conveniently control the start and stop of the drive motor remotely through the trigger button, and then control the rotation state of the inertial flywheel group 140, realizing the instant activation or shutdown of the stabilization assembly, enhancing the flexibility and response speed of the operation; since the inertial stabilization device can significantly reduce the flutter of the joystick, reducing the risk of slipping or inaccurate positioning with the target device during the operation, thus improving the safety of the operation and reducing the potential hazards in power maintenance and repair work; the combination of the trigger assembly and the stabilization assembly enables the joystick to adapt to different operating environments and work requirements, and the operator can adjust the working state of the stabilization assembly at any time according to the actual situation, improving the versatility and application range of the device.

[0036] A coupling is provided between the inertial flywheel group 140 and the drive motor, and the coupling is a permanent magnet coupling 150. The characteristics of the permanent magnet coupling 150 allow for more precise control of the rotation state of the inertial flywheel group 140, ensuring a smooth transition when the motor starts and stops, avoiding the impact caused by sudden acceleration or deceleration, and further enhancing the stability and accuracy of the operation. It can be understood that bearings can also be provided at both ends of the inertial flywheel group 140 to improve the stability during the operation of the inertial flywheel group 140. The use of bearings can significantly reduce the radial and axial runout when the inertial flywheel group 140 rotates, ensuring the smoothness of the flywheel group during high-speed rotation, reducing the flutter phenomenon caused by mechanical vibration, and improving the stability of the joystick.

[0037] Refer to Figures 1 to 3 , the rod body assembly 110 further includes a replaceable operating head 120, and the operating head 120 is connected to the operating part through a card slot. The quick replacement mechanism of the operating head 120 saves the time for preparing and switching tools. The operator can quickly respond to different operating tasks on-site without carrying a variety of special tools, significantly improving the work efficiency.

[0038] It is understandable that the rod assembly 110 can be composed of a variety of rods. In a first embodiment, the rod assembly 110 is composed of a plurality of telescopic round tubes connected end to end. The connection method of the telescopic round tubes is usually relatively simple, and the operator can quickly adjust the length of the operating rod without the need for complicated assembly steps, thereby improving work efficiency. In a second embodiment, the rod assembly 110 includes a plurality of connecting rods, and the head and tail of the connecting rods are respectively provided with threaded connection parts, and the plurality of connecting rods are connected by the threaded connection parts. The threaded connection provides a reliable mechanical connection method, ensuring the tightness and stability of the connection part. Even if it is subjected to a large torque during operation, the connection can remain firm, avoiding operational failure or safety accidents caused by unstable connection.

[0039] In this embodiment, the drive motor is preferably a DC motor 160. The DC motor 160 has a short start and stop response time and can quickly reach the required speed, which is very beneficial for high-voltage operation scenarios that require fast response.

[0040] The rod assembly 110 is made of insulating material. The operating rod made of insulating material can be safely used on a variety of electrical equipment, whether it is an outdoor power line or an indoor distribution cabinet, and can provide necessary electrical isolation.

[0041] The trigger button is connected to a Bluetooth transmitter module 170, and the drive motor is connected to a Bluetooth receiver module. The Bluetooth receiver module is used to receive wireless remote control signals from the Bluetooth transmitter module 170, thereby controlling the start and stop of the drive motor and achieving remote control of the inertial flywheel assembly 140. By controlling the drive motor via Bluetooth wireless remote control signals, the operator can control the start and stop of the inertial stabilizer from a safe distance away from high-voltage equipment, significantly improving operational safety and reducing the risk of electric shock.

[0042] A lithium battery module 180 is provided in the rod body assembly 110. The lithium battery module 180 is provided in the installation cavity. The lithium battery module 180 is electrically connected to the drive motor, the Bluetooth receiving module and the Bluetooth transmitting module 170. The built-in lithium battery module 180 frees the operating rod from dependence on an external power source. The operator can operate it at any location without worrying about the limitations of the power cord, thereby improving the flexibility and portability of the operation. It is understandable that the lithium battery module 180 is also equipped with a lithium battery protection board, which can monitor the charging and discharging status of the battery to prevent the battery from being overcharged or over-discharged, which helps to extend the service life of the lithium battery and avoid battery damage or safety hazards caused by overcharging or over-discharging.

[0043] An insulating gasket 130 is also provided at the end of the rod assembly 110. The insulating gasket 130 is adapted to the inner side wall of the rod assembly 110. When the insulating gasket 130 covers the end of the rod assembly 110, a sealed cavity is formed in the rod assembly 110. The insulating gasket 130 can effectively prevent dust, moisture and other impurities from entering the interior of the rod assembly 110, protect the electronic components and mechanical parts from the external environment, and extend the service life of the equipment.

[0044] In this embodiment, an inertial stabilization device applicable to a high-voltage insulating operating rod aims to improve the operating stability and safety of the operating rod in a high-voltage environment through the principle of the gyroscopic effect. The device consists of an inertial flywheel group 140, a DC motor 160, a permanent magnet coupling 150, a Bluetooth motor transmitting module, a Bluetooth receiving module, a lithium battery module 180 and a lithium battery charging protection board. The rotation state of the inertial flywheel is controlled by remotely controlling the motor through Bluetooth wireless remote control, so as to eliminate the flutter phenomenon.

[0045] When the operator issues a start command by triggering a button, the Bluetooth motor remote control board receives the signal and controls the start of the DC motor 160 through wireless remote control. The DC motor 160 drives the inertial flywheel to rotate at a high speed, generating a huge angular momentum, stabilizing the rod head of the operating rod and eliminating the flutter. When not affected by external forces, the rotation axis of the inertial flywheel will always stably point in one direction, improving the operation accuracy and stability. After the operation is completed, the operator triggers the button again, the motor stops, and the inertial flywheel gradually decelerates. It can significantly reduce the tremor of the operating rod in a high-voltage environment and improve the operation accuracy and safety. The inertial stabilization device of this embodiment is particularly suitable for high-voltage operations in the distribution network, such as opening and closing pole-mounted switchgear, isolating switches, drop-out switches, etc. Especially when the operating equipment is installed on a pole more than 5 meters above the ground, it can significantly improve the operation efficiency and safety.

[0046] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
