Description

Technical Field

Background Art

[0002] Traditional fixed switch cabinets have few control circuits and occupy a large space, which brings great inconvenience to production, storage, and maintenance. Moreover, they mainly rely on manual direct operation, unable to achieve computer intelligent management, and it is relatively difficult to implement more complex control logics. With the development of power grid infrastructure construction and power energy investment, the demand for electrical complete sets of equipment has increased year by year, the product upgrade speed has accelerated, the production equipment and processing technology have been significantly improved, and the performance of electrical equipment such as intelligentization, primary-secondary integration technology, and integrated integration has been significantly improved. Its content includes the acquisition and monitoring of distribution network data, distribution geographic information system, and customer management. Intelligent switch cabinets have emerged as the times require.

[0003] Intelligent switch cabinets are based on existing ordinary switch cabinets with analog meters and relays as monitoring and control equipment, cooperate with new intelligent meters, and are connected to the computer system in the central control room through their network communication interfaces to monitor electrical parameters such as voltage, current, active power, reactive power, power factor, frequency, and electricity consumption of each power supply and distribution circuit, monitor the opening and closing states and fault information of circuit breakers, control the opening and closing states of circuit breakers, and cooperate with various perfect remote monitoring software to achieve functions such as "four remote controls".

[0004] Intelligent switch cabinets have changed the concept of traditional switch cabinets and have characteristics such as multi-function, digitalization, networking, intelligentization, compact structure, and easy maintenance. They can meet the future needs of the power industry and have many advantages such as preventing / avoiding accidents, reducing equipment maintenance and repair time, and realizing data resource sharing. However, whether it is armored withdrawable or armored fixed switch cabinets, the basis for realizing intelligentization is first the electrification of switch cabinet operations. For armored fixed switch cabinets, typical solutions include that the upper disconnector, upper earthing switch, lower disconnector, and earthing switch must all achieve electric operation, so that the intelligentization (intelligent control) of the switch cabinet can be better realized.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 11 As shown, a multi-station programmed electric operating mechanism of the present invention comprises a frame 8, a driving motor 1 mounted on the frame 8, a transmission mechanism, a faceplate 2, a dial 3, a cam 6 and a micro switch 7. The faceplate 2, the dial 3 and the cam 6 are all rotatably mounted on the frame 8 through a rotating shaft. The driving motor 1 drives the dial 3 and the cam 6 to rotate synchronously through the transmission mechanism. A toggle mechanism is provided between the faceplate 2 and the dial for toggling the faceplate 2 to rotate 90° when the dial 3 rotates one circle. A release mechanism is provided between the cam 6 and the micro switch 7 for releasing the driving rod of the micro switch 7 to cut off the power supply of the driving device when the cam 6 rotates one circle. The driving motor 1 is energized to rotate forward or reversely for one circle to drive the faceplate 2 to reverse or rotate forward by 90°. At the same time, the micro switch 7 cuts off the power supply of the driving motor 1, so that the driving motor 1 completes the forward or reverse operation at any position, and at the same time, the faceplate 2 performs intermittent reverse or forward rotation by 90°.

[0034] In this embodiment, the dial 3 and the cam 6 are coaxially mounted, and the transmission mechanism adopts a gear pair, which is specifically composed of a large gear 4 and a small gear 5. The small gear 5 is mounted on the power output shaft of the driving motor 1, and the inner hexagonal hole of the small gear 5 cooperates with the outer hexagonal shaft 1.1 (power output shaft) of the driving motor 1, and the driving motor 1 drives the small gear 5 to rotate; the large gear 4 is mounted on the rotating shaft of the dial 3 and the cam 6, and the inner hexagonal hole of the large gear 4 cooperates with the main shaft 3.4 (outer hexagonal shaft) of the dial 3, and rotates simultaneously with the dial 3. The gear pair composed of the small gear 5 and the large gear 4 plays the role of transmitting motion and force.

[0035] In this embodiment, the toggle mechanism is composed of a notched roller groove 2.1 provided on the faceplate 2 and a pair of rotatable rollers 3.1 provided on the dial 3. The rollers 3.1 are adapted to the roller groove 2.1. Figure 9 As shown, there are eight roller grooves 2.1 evenly distributed on the circumference of the faceplate 2; Figure 10 , Figure 11 The dial 3 shown includes a mounting plate 3.3, a pin shaft 3.2, a main shaft 3.4 (a rotating shaft of the dial and the cam) and a roller 3.1. The mounting plate 3.3, the pin shaft 3.2 and the main shaft 3.4 are connected as a whole. The two pin shafts 3.2 are symmetrical and eccentric to the center of the main shaft 3.4 and are fixed on the mounting plate 3.3. The roller 3.1 forms a rotational fit with the pin shaft 3.2. The roller 3.1 can rotate forward and backward with the pin shaft 3.2 as the center.

[0036] In this embodiment, the release mechanism is composed of a small roller groove 6.1 provided on the cam 6 and a small roller 7.1 provided on the driving rod of the micro switch 7. Figure 6 As shown, the small roller groove 6.1 is a notched fan-shaped groove. The small roller 7.1 is driven into the small roller groove 6.1 as the cam 6 rotates and rolls along its inclined surface to release the driving rod of the micro switch 7 to cut off the power supply of the driving motor 1. The angle α between the center position of the small roller groove 6.1 and the inner hole of the cam 6 is 9°, and the vertex angle β of the small roller groove 6.1 is 132°, both of which are theoretical design values. The inner semicircular hole of the cam 6 cooperates with the outer semicircular hole of the main shaft 3.4 of the dial 3 to rotate simultaneously with the dial 3. The small roller groove 6.1 is a fan-shaped groove, which can adapt to the small roller 7.1 on the driving rod of the micro switch 7 to freely enter the small roller groove 6.1 when the cam 6 rotates forward or reverse, and cut off the power supply line of the driving motor 1.

[0037] like Figures 1 to 6, the frame 8 is composed of a first support plate 8.1, a second support plate 8.2, and a third support plate 8.3 that are arranged in sequence and fixed together. They are arranged at unequal distances and support the installation of the drive motor 1 and the microswitch 7, as well as the rotation of the gear pair composed of the large gear 4 and the small gear 5, the dial 3, the faceplate 2, and the cam 6. The drive motor 1 is installed on the first support plate 8.1, the faceplate 2 and the dial 3 are installed between the first support plate 8.1 and the second support plate 8.2, the large gear 4 and the small gear 5 are installed between the second support plate 8.2 and the third support plate 8.3, and the cam 6 and the microswitch 7 are installed on the outer side surface of the third support plate 8.3.

[0038] When the drive motor 1 is powered on, it drives the small gear 5 to rotate. The small gear 5 drives the large gear 4 to rotate. The large gear 4 is fitted and installed with the main shaft 3.4 on the dial 3 and rotates together with the dial 3. The pin shaft 3.2 fixed to the dial 3 drives the roller 3.1 that cooperates with the pin shaft 3.2 to rotate. The rotating roller 3.1 enters the roller groove 2.1 of the faceplate 2 and drives the faceplate 2 to rotate; the cam 4 is fitted and installed with the main shaft 3.4 on the dial 3 and rotates together with the dial 3. The microswitch 7 is fixedly installed on the third support plate 8.3.

[0039] The transmission principle of the present invention is:

[0040] ⑴ When the drive motor is powered on, the drive motor rotates in reverse, the drive motor drives the small gear to rotate in reverse, the small gear drives the large gear to rotate forward, and the dial rotates forward. When the dial rotates one circle, the cam releases the small roller on the microswitch drive rod, and the microswitch cuts off the power supply of the drive motor, and the drive motor stops rotating, completing the reverse rotation of the faceplate by 90°. The transmission process is shown in Figure 12 .

[0041] ⑵ When the drive motor is powered on, continue to drive the drive motor to rotate in reverse, drive the small gear to rotate in reverse, the small gear drives the large gear to rotate forward, and the dial rotates forward. When the dial rotates one circle, the cam releases the small roller on the microswitch drive rod, and the microswitch cuts off the power supply of the drive motor, and the drive motor stops rotating, completing the reverse rotation of the faceplate by another 90°.

[0042] ⑶ When the drive motor is powered on, the drive motor rotates forward, drives the small gear to rotate forward, the small gear drives the large gear to rotate in reverse, and the dial rotates in reverse. When the dial rotates one circle, the cam releases the small roller on the microswitch drive rod, and the microswitch cuts off the power supply of the drive motor, and the drive motor stops rotating, completing the forward rotation of the faceplate by 90°.

[0043] That is: When the drive motor is powered on and rotates in reverse, the turntable rotates 90°. The microswitch cuts off the power supply of the drive motor, and the drive motor stops rotating, completing the rotation of the turntable by 90°. Then, the drive motor rotates in reverse again to drive the turntable to rotate 90°, and the turntable rotates intermittently in the forward direction, each time rotating 90°. Conversely, when the drive motor is powered on and rotates forward, the turntable rotates 90°. The microswitch cuts off the power supply of the drive motor, and the drive motor stops rotating, completing the rotation of the turntable by 90°. Then, the drive motor rotates forward again to drive the turntable to rotate 90°, and the turntable rotates intermittently in the reverse direction, each time rotating 90°. In addition, the drive motor can complete forward or reverse rotation at any position, change the rotation direction of the motor, and perform forward or reverse rotation operations at any position. The turntable can also rotate intermittently in the forward and reverse directions, each time rotating 90°. Its working logic is as Figure 13 shown.
