TECHNICAL FIELD

[0001] The utility model relates to air switch technical field, concretely is an air switch automatic opening and closing device and mechanical arm. BACKGROUND

[0002] Air switch is mainly composed of contact system, arc extinguishing system, operating mechanism, thermal release, electromagnetic release and shell structure, and can automatically cut off the circuit when overload, short circuit and other faults occur in the circuit. Among them, the operating mechanism has manual operation function, and the air switch can be tripped by moving the operating handle, thereby cutting off the circuit in time.

[0003] In the prior art, when it is necessary to actively open and close the air switch, manual operation is generally relied on. If the work scene requires frequent control of the air switch, the operator has to repeatedly manually operate, greatly increasing the labor cost and time cost, and the efficiency is very low. In special scenes where the air switch position is difficult to access, such as the air switch is installed in a narrow, high or closed space, manual operation is almost impossible, which not only seriously hinders the normal work process, but also may cause serious consequences when the circuit fails due to the inability to operate the air switch in time. Therefore, we propose an air switch automatic opening and closing device and a mechanical arm to solve the above problems. UTILITY MODEL CONTENTS

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Embodiment one: please refer to Figures 1 to 3 The utility model discloses an automatic opening and closing device of air switch, including: casing 1, synchronous belt 3 and dial block 5, for solving the problem of inconveniently opening and closing the air switch in prior art.

[0026] Specifically, one side of the casing 1 is provided with a through port 2 for the operation handle of the air switch to extend into the casing 1. In the embodiment, the size of the through port 2 is greater than that of the air switch, so that the operation handle of the air switch can be completely extended into the casing 1 and smoothly contact the synchronous belt 3 in the casing 1.

[0027] In addition, the synchronous belt 3 is arranged in the casing 1, and a driving assembly 4 for driving the synchronous belt 3 to operate is installed in the casing 1. In the embodiment, the driving assembly 4 includes two pulleys 401 rotatably connected in the casing 1 and matched with the synchronous belt 3, and a servo motor 402 is installed outside the casing 1 and in transmission connection with one of the pulleys 401. When the servo motor 402 works, it can drive the corresponding pulley 401 to rotate, thereby driving the synchronous belt 3 to rotate forward or reverse.

[0028] When the synchronous belt 3 rotates, in order to be able to dial the operation handle of the air switch, the dial block 5 is provided with at least one and fixed to the outer surface of the synchronous belt 3 for dialing the operation handle of the air switch. In this way, whether the synchronous belt 3 rotates forward or reverse, the dial block 5 can contact the operation handle to realize the dialing action of the operation handle, and then easily achieve the opening and closing operation of the air switch.

[0029] In the embodiment, the projection of the dial block 5 on the horizontal plane is trapezoidal. In actual operation process, the dial block 5 can realize more ideal interaction with the operation handle of the air switch by virtue of its special geometric shape. The combination of the inclined side and the base of the trapezoid can generate more stable and efficient driving force when the synchronous belt operates to drive the dial block 5 to dial the operation handle, so as to ensure that the air switch can accurately and quickly respond to the control instruction and complete the opening and closing action whether in normal working state or complex working condition.

[0030] With the above structure, when the air switch needs to be turned on or off, the operating handle of the air switch is first passed through the opening 2 on the housing, so that it contacts the synchronous belt 3, causing the contact part of the synchronous belt 3 to deform inward. At this time, based on the tension stress of the synchronous belt 3, the synchronous belt 3 and the operating handle can fit tightly together, forming an inward tangent shape. This shape can ensure good friction and fit between the two, laying a solid foundation for subsequent power transmission.

[0031] Next, the servo motor 402 is started, driving the synchronous belt 3 to rotate in a predetermined direction. As the synchronous belt 3 rotates, the toggle block 5 fixed on its outer surface also moves. When the toggle block 5 touches the operating handle, it will move the operating handle, thus smoothly realizing the opening or closing operation of the air switch. The whole process is efficient and precise.

[0032] Example 2: Please refer to Figures 4 to 5 This embodiment also proposes an automatic air switch opening and closing device. The difference between this embodiment and Embodiment 1 is that the projection of the toggle block 5 onto the horizontal plane is triangular. Compared to the trapezoidal projection of the toggle block 5 in Embodiment 1, this triangular projection toggle block 5 possesses unique geometric features. In practical applications, the acute vertices and three sides of the triangle can provide different force application angles and toggle effects under specific working conditions. Based on actual needs, users can flexibly choose toggle blocks 5 with trapezoidal or triangular projection shapes to adapt to diverse working conditions and optimize the overall performance of the automatic air switch opening and closing device.

[0033] Furthermore, it is important to emphasize that the shape of the toggle block 5 is not limited to the trapezoidal or triangular shapes mentioned earlier. In practical applications, its shape offers extensive customizability, allowing for diverse designs to suit various complex and unique application scenarios.

[0034] For example, in scenarios where there are special requirements for the force and direction of the operating handle, the lever 5 can be designed as a hook. The hook-shaped structure can use its unique bending shape to more accurately hook onto a specific part of the operating handle during the operation of the synchronous belt 3, applying a stable and targeted pulling force, thereby achieving more precise control of the operating handle.

[0035] In summary, the shape of the dial 5 can be customized to have different geometric features according to the actual working conditions, in order to meet various demanding and diverse application requirements.

[0036] Example 3: Please refer to Figure 6The embodiment also provides a mechanical arm, which comprises the air switch automatic opening and closing device provided in the first embodiment or the second embodiment, and further comprises a mechanical arm body 6, and the shell 1 is fixed to the tail end of the mechanical arm body 6. In this way, the air switch automatic opening and closing device can be accurately delivered to various complex environment positions by the flexible movement ability of the mechanical arm body 6, efficient execution of the automatic operation of the air switch is realized, and the application range of the automatic control of the air switch in different scenes is greatly expanded.

[0037] The installation position of the air switch automatic opening and closing device is not limited to the tail end of the mechanical arm, and based on the diversified needs of actual application scenes, the air switch automatic opening and closing device can also be installed at the tail end of other equipment. For example, the air switch automatic opening and closing device is installed at the tail end of an automatic guided vehicle (AGV), so that the AGV can perform automatic operation on the air switch at a specific position when the AGV shuttles in an industrial production workshop, and the smooth advancement of the intelligent production process is facilitated; or the air switch automatic opening and closing device is installed at the bottom of a drone, so that the drone can remotely realize automatic control of the air switch in a scene such as an air switch near an overhead power transmission line without personnel climbing, and the safety and efficiency of the inspection work are significantly improved.

[0038] It should be noted that the relational terms such as first and second and the like in this text are used only to differentiate one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the element defined by the statement "including a" does not exclude the presence of another identical element in the process, method, article or equipment including the element.

[0039] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
