Description

Technical Field

[0001] This invention relates to a circuit breaker indicator and a switch operating mechanism, belonging to the technical field of high-voltage electrical operating mechanisms. Background Technology

[0002] In the prior art, the fast grounding mechanism installed on power equipment usually uses a circuit breaker indicator ball to indicate the circuit breaker status. Specifically, the circuit breaker indicator ball is rotated by the rotation of the output shaft of the mechanism to change the indication status of the circuit breaker indicator ball.

[0003] Currently, the direction of the opening and closing indication of the fast grounding mechanism generally needs to be changed according to the user's convenience. When the opening and closing indication direction is perpendicular to the direction of the mechanism's output shaft, that is, when the rotation axis of the opening and closing indicator ball is perpendicular to the rotation axis of the mechanism's output shaft, the traditional solution is to set a pair of meshing bevel gears between the mechanism's output shaft and the opening and closing indicator ball.

[0004] However, the above-mentioned traditional solutions have significant limitations. Specifically, the processing technology of bevel gears is complex and requires high processing accuracy and assembly. If the processing accuracy is low or the assembly is not up to standard, the operation will result in noise and severe wear, which will reduce the service life. If the processing accuracy of bevel gears is high, the cost will also be high, which will reduce the competitiveness of the product. Summary of the Invention

[0005] The purpose of this invention is to provide a circuit breaker opening / closing indicator device to solve the problem of high cost and reduced product competitiveness caused by changing the circuit breaker opening / closing indication direction through bevel gears in the prior art; the purpose of this invention is also to provide a switch operating mechanism to solve the above problems.

[0006] To address the aforementioned issues, the opening and closing indicator device of this invention employs the following technical solution:

The support rod, connecting rod, and crank arm together form a parallelogram mechanism with the switch operating mechanism. The circuit breaker opening / closing indicator also includes an indicator for displaying the opening / closing status and a rotating shaft fixedly connected to the indicator and rotatably mounted on the main body of the mechanism. The axis of the rotating shaft is perpendicular to the axis of the output shaft. A connecting component assembly is provided between the rotating shaft and the connecting rod to drive the rotating shaft to rotate when the connecting rod is activated.

[0008] The beneficial effects of the above technical solution are as follows: This invention innovatively proposes a circuit breaker indicator device. In this circuit breaker indicator device, the support rod fixedly connected to the output shaft, the crank arm rotatably mounted on the switch operating mechanism, and the connecting rod hinged between the support rod and the crank arm together with the switch operating mechanism form a parallelogram mechanism. Furthermore, since the indicator for displaying the circuit breaker status is fixedly connected to a rotating shaft rotatably mounted on the main body of the mechanism, and a connecting component assembly is provided between the rotating shaft and the connecting rod to drive the rotating shaft to rotate when the connecting rod moves, when the output shaft rotates, it can drive the above-mentioned parallelogram mechanism to move, and then drive the rotating shaft to rotate through the connecting component assembly to realize the change of the circuit breaker status. Compared with the bevel gear meshing transmission in the prior art, since the circuit breaker indicator device of this invention is composed of a support rod, connecting rod, crank arm, and connecting component assembly, the structure is simple, easy to process and manufacture, which helps to reduce costs and improve product competitiveness.

[0009] Furthermore, the connecting component assembly includes a connecting plate that is anti-rotatingly connected to the rotating shaft, and a driving structure is provided on the connecting rod for driving the connecting plate to rotate around the axis of the rotating shaft.

[0010] The beneficial effects of the above technical solution are as follows: the connecting plate and drive structure not only facilitate the drive of the rotating shaft, but also simplify the connecting parts assembly to a certain extent, which is conducive to the processing of the connecting parts assembly.

[0011] Furthermore, the connecting component assembly also includes a transmission rod that is connected to the connecting plate for transmission, and the driving structure is a socket or slot provided on the connecting rod for the transmission rod to be inserted; or, the driving structure is a transmission rod fixed on the connecting rod, and the connecting plate is provided with a socket or slot for the transmission rod to be inserted.

[0012] The beneficial effects of the above technical solution are as follows: by cooperating with the transmission rod and the insertion hole or slot, it is not only convenient for the connecting rod to drive the rotation of the connecting plate, but also to a certain extent to increase the distance between the connecting plate and the parallelogram mechanism, which helps to avoid motion interference between the connecting plate and the parallelogram mechanism.

[0013] Furthermore, a socket or slot is provided on the connecting rod, which includes a connecting rod body and a fixing block provided on the connecting rod body, and the socket or slot is provided on the fixing block.

[0015] Furthermore, the transmission rod is arranged parallel to the rotating shaft.

[0016] The beneficial effects of the above technical solution are: it optimizes the structural layout between the transmission rod and the rotating shaft, saves space in the arrangement direction between the transmission rod and the rotating shaft, and facilitates the arrangement of both.

[0017] Furthermore, the opening and closing indicator device also includes a mounting base for fixing to the main body of the mechanism. The mounting base includes a fixing plate for fixing to the main body of the mechanism and side plates fixed on opposite sides of the fixing plate. The rotating shaft is rotatably mounted on the two side plates.

[0018] The beneficial effects of the above technical solution are as follows: the mounting base facilitates the rotational installation of the rotating shaft on the main body of the mechanism; the mounting base facilitates the fixing between the mounting base and the main body of the mechanism through the fixing plate, and the two side plates facilitate the rotational installation of the rotating shaft on the mounting base.

[0019] Furthermore, the rotating shaft is stepped, comprising a large-diameter section and a small-diameter section. The small-diameter section is rotatably mounted on the mounting base, and the stepped end face between the large-diameter section and the small-diameter section is used to engage with the side plate for a stop.

[0020] The beneficial effects of the above technical solution are that it can achieve a fixed connection with the indicator through the large diameter section of the rotating shaft, and can also achieve the rotational installation of the rotating shaft on the mounting base through the small diameter section of the rotating shaft. At the same time, the stability of the rotating shaft on the mounting base can be ensured by the stop fit between the stepped end face between the large diameter section and the small diameter section and the side plate.

[0021] Furthermore, the crank arm is used to prevent rotation of the drive shaft of the auxiliary switch of the switch operating mechanism, so that after the output shaft rotates to the position, the drive shaft is driven to rotate a certain angle through the parallelogram mechanism, and then the main body of the control mechanism is stopped by the auxiliary switch.

[0022] The beneficial effects of the above technical solution are as follows: by connecting the crank arm and the drive shaft of the auxiliary switch to prevent rotation, the linkage between the output shaft and the drive shaft of the auxiliary switch can be realized through the parallelogram mechanism. After the output shaft rotates to the position, the main body of the mechanism can be stopped by the auxiliary switch, which is beneficial to the reliability of the main body of the mechanism.

[0023] Furthermore, the crank arm is V-shaped and includes a first connecting arm and a second connecting arm. One of the first connecting arm and the second connecting arm is hinged to the connecting rod, and the other is used to connect the drive shaft of another auxiliary switch in the main body of the switch operating mechanism.

[0024] The beneficial effects of the above technical solution are that it can facilitate the hinge connection between the crank arm and the connecting rod through the first connecting arm, and at the same time, it can facilitate the linkage between the crank arm and another auxiliary switch in the switch operating mechanism through the second connecting arm.

[0027] The beneficial effects of the above technical solution are as follows: This invention innovatively proposes a switch operating mechanism. In this switch operating mechanism, the support rod fixedly connected to the output shaft, the crank arm rotatably mounted on the switch operating mechanism, and the connecting rod hinged between the support rod and the crank arm together with the switch operating mechanism form a parallelogram mechanism. Furthermore, since the indicator for displaying the opening and closing status is fixedly connected to a rotating shaft rotatably mounted on the main body of the mechanism, and a connecting component assembly is provided between the rotating shaft and the connecting rod to drive the rotating shaft to rotate when the connecting rod moves, when the output shaft rotates, it can drive the above-mentioned parallelogram mechanism to move, and then drive the rotating shaft to rotate through the connecting component assembly to realize the change of the opening and closing indication status.

Detailed Implementation

[0046] Embodiment 1 of the switch operating mechanism in this invention:

[0047] This invention innovatively proposes a switch operating mechanism. The mechanism comprises a support rod, connecting rod, and crank arm forming a parallelogram, and a rotating shaft rotatably mounted on the main body of the mechanism and fixedly connected to an indicator for displaying the open / closed status. A connecting component assembly is provided between the rotating shaft and the connecting rod to drive the rotating shaft's rotation when the connecting rod moves. Thus, when the output shaft of the mechanism rotates, it drives the parallelogram mechanism, which in turn drives the rotating shaft to rotate via the connecting component assembly, thereby changing the open / closed status indication. Compared to the bevel gear meshing transmission in the prior art, the open / closed indicator device of this invention, composed of a support rod, connecting rod, crank arm, and connecting component assembly, has a simple structure, is easy to manufacture, helps reduce costs, and improves product competitiveness.

[0048] Specifically, the switch operating mechanism includes a main body and an opening / closing indicator device. The main body includes a frame 10. In this embodiment, the opening / closing indicator device is used to display the opening / closing status of the fast grounding mechanism, such as... Figure 1As shown, the opening and closing indicator device includes a support rod 30, a connecting rod 40, and a crank arm 50. The connecting rod 40 is anti-rotatingly connected to the output shaft 20, and the axis of the output shaft 20 extends horizontally. The crank arm 50 is fixedly connected to the drive shaft 61 of the auxiliary switch 60 in the fast grounding mechanism. The crank arm 50 is rotatably mounted on the fast grounding mechanism through its fixed connection with the drive shaft 61. The crank arm 50 is V-shaped and includes a first connecting arm 51 and a second connecting arm 52. The second connecting arm 52 is used for transmission connection with the drive shaft of another auxiliary switch in the fast grounding mechanism. One end of the connecting rod 40 is hinged to the end of the support rod 30 away from the output shaft 20, and the other end is hinged to the first connecting arm 51. The support rod 30, connecting rod 40, crank arm 50, and quick grounding mechanism together form a parallelogram mechanism. When the output shaft 20 rotates, the output shaft 20 can drive the parallelogram mechanism to move, which in turn can drive the transmission shaft 61 of the auxiliary switch 60 to move. That is, the output shaft 20 can achieve linkage with the transmission shaft 61 through the parallelogram mechanism. After the output shaft 20 rotates to the position, the output shaft 20 can drive the transmission shaft 61 to rotate a certain angle through the parallelogram mechanism. In addition, the auxiliary switch 60 can cut off the power supply line of the output shaft rotation drive motor, control the main body of the mechanism to stop working, and ensure the rotation angle of the output shaft 20.

[0049] like Figure 1 As shown, the opening and closing indicator device also includes an indicator for displaying the opening and closing status, a rotating shaft 90 fixedly connected to the indicator, and a mounting base 100 fixed on the mechanism frame 10. The mounting base 100 is U-shaped and includes a fixing plate 101 fixed to the mechanism frame 10, and an upper side plate 102 and a lower side plate 103 fixedly connected to opposite sides of the fixing plate 101. In this embodiment, the indicator is an opening and closing indicator ball 110. The axis of the rotating shaft 90 extends vertically and is perpendicular to the axis of the output shaft 20. The rotating shaft 90 is stepped and includes a large-diameter section 91 and a small-diameter section 92. The opening and closing indicator ball 110 is fixed to the end of the large-diameter section 91. The small-diameter section 92 is rotatably mounted on the upper side plate 102 and the lower side plate 103, and the stepped end face between the large-diameter section 91 and the small-diameter section 92 engages with the upper side plate 102.

[0050] When the parallelogram mechanism operates, the connecting rod 40 moves in the left-right direction. A connecting component assembly is provided between the rotating shaft 90 and the connecting rod 40 to drive the rotating shaft 90 to rotate when the connecting rod 40 operates. Figure 1As shown, the connecting component assembly includes a connecting plate 80 and a transmission rod 70. The connecting plate 80 is anti-rotatingly connected to the rotating shaft 90, and the transmission rod 70 is arranged parallel to the rotating shaft 90. One end of the transmission rod 70 is drivingly connected to the connecting plate 80. The connecting rod 40 is provided with an insertion slot for inserting the other end of the transmission rod 70. Specifically, the connecting rod 40 includes a connecting rod body 41 and a fixing block 42 fixed on the connecting rod body 41. The slot is provided on the fixing block 42 and is a U-shaped groove. When the connecting rod 40 moves left and right, the U-shaped groove and the transmission rod 70 cooperate to drive the transmission rod 70 to swing around the axis of the rotating shaft 90, thereby driving the connecting plate 80 to rotate around the axis of the rotating shaft 90. The rotation of the connecting plate 80 can drive the rotation of the rotating shaft 90, thereby changing the indication state of the opening and closing indicator ball 110. The U-shaped groove constitutes a driving structure provided on the connecting rod for driving the connecting plate 80 to rotate around the axis of the rotating shaft 90.
