Detailed Implementation

[0016] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0017] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0018] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1 , 2 As shown in Figure 3, the portable remote opening and closing operation tool for the circuit breaker includes a base, an adjustment mechanism, a protective housing 2, an operating lever 3, a drive motor 7, and a control module. The upper side of the base is provided with an adjustment mechanism that allows the protective housing 2 to move left and right and back and forth. The lower inner side of the protective housing 2 is provided with an operating lever 3, which is U-shaped with its opening facing upward. The outer left and right sides of the operating lever 3 are fitted with guide sleeves 5 that are fixedly installed together with the corresponding positions on the inner side of the protective housing 2. The lower middle side of the operating lever 3 is fixed with an actuating rod 4. The lower center of the actuating rod 4 is provided with a threaded hole that runs vertically through it. A screw rod 6 is screwed into the threaded hole. The upper inner side of the protective housing 2 is fixedly installed with a drive motor 7. The lower end of the output shaft of the drive motor 7 is connected to the upper end of the screw rod 6. The drive motor 7 is electrically connected to the control module.

[0019] Depending on the requirements, the control module is a known technology, such as an AHS series button control module or a remote control and programmable control module that are electrically connected together. The operating lever 3 and the touch lever 4 are integrated. The lower end of the touch lever 4 can be fixed with a contact made of flexible material. The drive motor 7 is a known technology, such as a geared motor or a stepper motor with a reducer. The upper end of the screw hole extends to the inside of the operating lever 3.

[0020] During use, the guide sleeve 5 can constrain the vertically moving operating lever 3, preventing it from swinging left and right and causing the circuit breaker opening / closing button 1 or handle to fail to operate. The control module can be set to a safe position to ensure safety during operation. When the touch rod 4 is installed in the forward direction, the operating lever 3 is above the touch rod 4. The drive motor 7 drives the touch rod 4 to move downward. After the lower end of the touch rod 4 moves downward, the circuit breaker opening / closing button 1 can be operated. When the touch rod 4 is installed in the reverse direction, the operating lever 3 is below the touch rod 4. That is, after the touch rod 4 rotates 180 degrees, it is screwed together with the screw rod 6. The drive motor 7 drives the touch rod 4 to move downward. After the lower end of the operating lever 3 moves downward, the circuit breaker opening / closing handle can be operated.

[0021] This application solves the problem that circuit breakers on switchgear cannot be remotely operated in the event of a failure in the background operating unit, thus protecting the personal safety of maintenance personnel. The portable remote opening and closing operation tool for circuit breakers is easy to operate, requires no modification to the current equipment, simulates manual operation, prevents damage to the equipment, and the touch rod 4, which can be installed in both forward and reverse directions, can be used in conjunction with three-dimensional movement and can be adapted to the operation of all current switchgear circuit breakers.

[0022] The aforementioned portable remote opening and closing operation tool for circuit breakers can be further optimized and / or improved according to actual needs: Example 2: As an optimization of the above examples, as shown in the appendix.

[0023] Based on the requirements, a voice-activated switch is a known existing technology. When the lower end of the trigger lever 4 moves downwards, it presses down on the circuit breaker's open / close button 1 or handle. When the circuit breaker's open / close button 1 or handle opens or closes, it will emit a sound. After the voice-activated switch collects the sound information, it sends it back to the control module. Upon receiving the information, the control module stops the drive motor 7. This prevents the drive motor 7 from continuing to rotate and causing the screw 6 to continue moving, which could damage the circuit breaker's open / close button 1 or handle.

Figure 1 , 2As shown, the base includes a front slide 8, a left slide 9 and a fixed plate 10, the fixed plate 10 is L-shaped, the outer side of the left part of the fixed plate 10 is slidingly installed along the front-to-back direction and is provided with the left slide 9, the outer side of the front part of the fixed plate 10 is slidingly installed along the left-to-right direction and is provided with the front slide 8, the upper side of the left slide 9 is fixedly installed with a first fixed rod 11, the right side of the upper part of the first fixed rod 11 is fixedly installed with a first sliding rod 12, the upper left side of the protective shell 2 is provided with a first sliding hole penetrating left and right, the outer side of the right part of the first sliding rod 12 is slidingly installed in the first sliding hole, the upper side of the front slide 8 is fixedly installed with a second fixed rod 13, the rear side of the upper part of the second fixed rod 13 is fixedly installed with a second sliding rod 14, the upper front side of the protective shell 2 is provided with a second sliding hole penetrating front and back and staggered with the first sliding hole vertically, the outer side of the rear part of the second sliding rod 14 is slidingly installed in the second sliding hole.

[0025] According to the needs, the first fixed rod 11 and the first sliding rod 12 are integrally arranged, and the second fixed rod 13 and the second sliding rod 14 are integrally arranged. In the use process, through such arrangement, the fixed rod and the sliding rod can not only support the protective shell 2, but also can drive the protective shell 2 to move left and right and front and back during the movement of the slide, so as to quickly correspond the position of the screw rod 6 with the on-off button 1 or the handle of the circuit breaker on the operating switch cabinet, and facilitate the subsequent operation.

[0026] Embodiment four: as an optimization of the above-mentioned embodiments, as shown in the accompanying drawings Figure 1 As shown, the lower side of the fixed plate 10 is provided with a plurality of downwardly opening installation grooves at intervals along the length direction, and each installation groove is fixedly installed with a magnet 18.

[0027] In the use process, the magnetic attraction method is used to fix the base on the steel panel of the switch cabinet, the position of the protective shell 2 is fixed above the on-off button 1 or the handle of the circuit breaker by adjusting the positions of the front slide 8 and the left slide 9, through such arrangement, the fixed plate 10 and the circuit breaker body can be quickly installed together, and the disassembly and assembly are convenient.

[0033] The driving motor 7 in the embodiment is a step motor with a speed reducer, and 45° forward, 45° reverse, 2mm forward, 2mm backward, and 5 emergency stop switch buttons are arranged on the remote controller. When the operating breaker opening and closing handle, the 45° forward and 45° reverse switch buttons are used, and the 45° forward is defined as the step motor rotating 360° clockwise, which is changed to rotating 45° after the speed reducer (the transmission ratio between the output shaft of the step motor and the screw rod 6 is 8). When the breaker opening and closing button 1 is operated, the 2mm forward and 2mm backward switch buttons are used, and the 45° forward 2mm is defined as the step motor rotating 8 rounds clockwise, which is changed to rotating 1 round after the speed reducer.
