Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission and distribution isolation operating mechanisms, and particularly relates to an Internet of Things electric isolation operating mechanism. Background Art

[0002] With the rapid development of the Internet of Things (IoT) technology, more and more devices are connected to the network, forming a huge device ecosystem. These devices generate a large amount of data during their daily operations, and the processing and analysis of this data are of great significance for the efficient management and intelligent application of the devices.

[0003] Currently, in a switch cabinet a, a disconnector (such as Figure 7 ) is generally installed. The opening and closing operations of the disconnector can generally be realized through an operating mechanism, which is mainly divided into an electric isolation operating mechanism and a manual isolation operating mechanism. The existing electric isolation operating mechanism usually has two motors that drive the isolation shaft and the grounding shaft respectively through a transmission mechanism to realize the opening and closing operations of the isolation and the opening and closing operations of the grounding. A spring energy storage mechanism is connected between the isolation shaft and the grounding shaft to realize the compression and release of energy required by the isolation shaft and the grounding shaft. For example, the document of the national patent application CN202322681419.5 records a double-motor-controlled isolation operating mechanism. By setting an isolation driving motor and a grounding driving motor to separately control the isolation operating shaft and the grounding operating shaft, the isolation driving motor and the isolation operating shaft are driven through a first reduction transmission component (gear set), and the grounding driving motor and the grounding operating shaft are driven through a second reduction transmission component (gear set). During grounding operation, the isolation driving motor is operated to cause the isolation operating shaft to rotate to the open position, and the grounding driving motor is operated to cause the grounding operating shaft to rotate to the closed position, and the main shaft acts accordingly to achieve grounding closing; during isolation operation, the grounding driving motor is operated to cause the grounding operating shaft to rotate to the open position, and the isolation driving motor is operated to cause the isolation operating shaft to rotate to the closed position, and the main shaft acts accordingly to achieve isolation closing. This isolation operating mechanism has a simple and reliable structure, low production cost, and is very convenient for later maintenance.

[0004] However, when a spring energy storage mechanism is connected between the isolation shaft and the grounding shaft, if this spring energy storage mechanism is damaged, during the opening and closing operations of the isolation shaft and the grounding shaft for isolation and the opening and closing operations of the grounding, it will affect both the isolation shaft and the grounding shaft at the same time, thereby reducing the stability and reliability of the disconnector and the grounding switch, and increasing the difficulty of later maintenance. Summary of the Utility Model

[0005] In view of the problem in the prior art that when a spring energy storage mechanism is connected between the isolating shaft and the earthing shaft and the spring energy storage mechanism is damaged, during the opening and closing operations for isolating the isolating shaft and the earthing shaft and the opening and closing operations for earthing, it will affect both the isolating shaft and the earthing shaft at the same time, thus reducing the stability and reliability of the disconnector and the earthing switch and increasing the difficulty of later maintenance, the following technical solutions are proposed:

[0006] An Internet of Things electric isolating operating mechanism includes an operating mechanism, on which there is a frame. The frame includes a first panel and a second panel. An isolating shaft is connected to the frame, and a number of disconnectors are installed on the isolating shaft. The mechanism further includes:

[0007] A driving mechanism, which is installed on the first panel, and the isolating shaft is connected to the driving mechanism;

[0008] An energy storage mechanism, which is located between the first panel and the second panel and is connected to the isolating shaft.

[0009] As a preference of the above technical solution, the energy storage mechanism includes a transmission frame, which is installed around the isolating shaft. There are protrusions on the transmission frame. An energy storage component is installed between the first panel and the second panel. The energy storage component includes a first spring seat and a second spring seat. The first spring seat is installed between the first panel and the second panel, and the second spring seat is installed inside the transmission frame. A guide rod and a spring are respectively connected between the first spring seat and the second spring seat.

[0010] As a preference of the above technical solution, two limit posts are installed between the first panel and the second panel, and recessed parts for cooperating with the limit posts are provided on both sides of the protrusions.

[0011] As a preference of the above technical solution, the driving mechanism includes a servo motor, which is installed on the first panel. A main gear is provided at the output end of the servo motor. A driven gear is installed around the isolating shaft, and the main gear meshes with the driven gear.

[0012] As a preference of the above technical solution, a control mechanism is installed on the isolating shaft and the first panel. The control mechanism includes a cam, which is installed around the isolating shaft. A first microswitch and a second microswitch are respectively installed on the first panel. The cam touches the first microswitch or the second microswitch during the process of rotating around the isolating shaft.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model separately sets an energy storage mechanism at the isolating shaft. In this way, when the energy storage mechanism is damaged, it only affects the isolating shaft and does not affect the earthing shaft, thus ensuring the stability and reliability of the disconnector and reducing the difficulty of later maintenance;

[0015] 2. The utility model is provided with an energy storage mechanism. During application, the energy storage mechanism plays a role in assisting the rotation of the transmission frame, improving the speed of the disconnector during opening and closing, thereby enhancing the safety during operation. At the same time, the limit post limits the transmission frame to prevent excessive rotation of the isolation shaft, thus avoiding damage. Most importantly, it improves the stability and reliability of the disconnector during opening and closing.

[0016] 3. The utility model is provided with a control mechanism. Through the control mechanism, the servo motor can be accurately controlled to stop running, enabling the isolation shaft to stop rotating at a relatively accurate position and preventing damage to the isolation shaft caused by excessive rotation.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0027] First of all, it should be noted that the Internet of Things is a network that connects any item to the Internet through information sensing devices, exchanges and communicates information according to agreed protocols, and realizes intelligent identification, positioning, tracking, monitoring, and management. This case is precisely based on Internet of Things technology to achieve remote control of disconnectors, and can control the disconnectors to switch between the closed state and the open state.

[0028] Embodiment

[0029] As Figures 1 - 6 shown, an Internet of Things electric isolating operating mechanism includes an operating mechanism 1. A frame 2 is provided on the operating mechanism 1. The frame 2 includes a first panel 21 and a second panel 22. An isolating shaft 7 is connected to the frame 2, and a number of disconnectors 5 are installed on the isolating shaft 7; The mechanism further includes:

[0030] A driving mechanism 3, the driving mechanism 3 is installed on the first panel 21, and the isolating shaft 7 is connected to the driving mechanism 3;

[0031] An energy storage mechanism 4, the energy storage mechanism 4 is located between the first panel 21 and the second panel 22 and is connected to the isolating shaft 7.

[0032] In actual application of this embodiment, the driving mechanism 3 drives the isolating shaft 7 to rotate, and at the same time the energy storage mechanism 4 assists the isolating shaft 7 to rotate, thereby ensuring the stability when the isolating shaft 7 rotates, and further ensuring the stability and reliability of the disconnector 5.

[0033] The advantage of the present utility model is that on the basis of the existing technology, the isolating shaft 7 and the grounding shaft are separately arranged, so that the isolating shaft 7 is used for a separate energy storage mechanism 4. In this way, when the energy storage mechanism 4 is damaged, only the isolating shaft 7 is affected, rather than the grounding shaft, thereby ensuring the stability and reliability of the disconnector 5 and reducing the difficulty of later maintenance.

[0034] Furthermore, the energy storage mechanism 4 includes a transmission frame 41. The transmission frame 41 is installed around the isolating shaft 7. A protrusion 411 is provided on the transmission frame 41. An energy storage member 42 is installed between the first panel 21 and the second panel 22. The energy storage member 42 includes a first spring seat 421 and a second spring seat 422. The first spring seat 421 is installed between the first panel 21 and the second panel 22, and the second spring seat 422 is installed inside the transmission frame 41. A guide rod 423 and a spring 424 are respectively connected between the first spring seat 421 and the second spring seat 422.

[0035] Among them, the guide rod 423 is telescopic, so as to provide a compression space for the spring 424, and the spring 424 is always in a compressed state.

[0036] In actual application of this embodiment, the isolation shaft 7 rotates to drive the transmission frame 41 to rotate. During the rotation of the transmission frame 41, the guide rod 423 contracts, and the spring 424 continues to be compressed for energy storage. When the transmission frame 41 rotates to be in the same straight line as the guide rod 423, the spring 424 will release energy to press the transmission frame 41 downward, thereby assisting the transmission frame 41 to rotate and making the disconnecting switch 5 in the open state; on the contrary, when the isolation shaft 7 rotates in the opposite direction, the spring 424 releases energy to squeeze the transmission frame 41 laterally, also assisting the transmission frame 41 to rotate and making the disconnecting switch 5 in the closed state; in this way, the speed of the disconnecting switch 5 during opening and closing can be increased, thereby improving the safety during operation.

[0037] Further, two limit posts 43 are installed between the first panel 21 and the second panel 22, and recessed portions for cooperating with the limit posts 43 are provided on both sides of the protrusion 411.

[0038] In actual application of this embodiment, the limit posts 43 can limit the transmission frame 41 after the transmission frame 41 rotates, avoiding excessive rotation of the isolation shaft 7 and thus damage. Most importantly, it improves the stability and reliability of the disconnecting switch 5 during opening and closing.

[0039] Further, the driving mechanism 3 includes a servo motor 31. The servo motor 31 is installed on the first panel 21, a main gear 32 is provided at the output end of the servo motor 31, and a driven gear 33 is installed around the isolation shaft 7. The main gear 32 meshes with the driven gear 33.

[0040] In actual application of this embodiment, by starting the servo motor 31, the main gear 32 rotates, thereby driving the driven gear 33 to rotate, and further rotating the isolation shaft 7.

[0041] Further, a control mechanism 6 is installed on the isolation shaft 7 and the first panel 21. The control mechanism 6 includes a cam 61. The cam 61 is installed around the isolation shaft 7. A microswitch one 62 and a microswitch two 63 are respectively installed on the first panel 21. The cam 61 touches the microswitch one 62 or the microswitch two 63 during the rotation around the isolation shaft 7.

[0042] Among them, the microswitch one 62 and the microswitch two 63 are connected to an external control unit, the control unit is connected to the servo motor 31, the microswitch one 62 and the microswitch two 63 transmit signals to the control unit, and the control unit controls the servo motor 31 to stop running according to the signals, thereby controlling the stop rotation of the isolation shaft 7.

[0043] In actual application of this embodiment, when the isolation shaft 7 rotates, it will drive the cam 61 to rotate. During the rotation of the cam 61, it will touch either the microswitch one 62 or the microswitch two 63. When it touches the microswitch one 62 or the microswitch two 63, the servo motor 31 stops running, the isolation shaft 7 stops rotating, and the disconnecting switch 5 is in the open or closed state, making the position of the isolation shaft 7 accurate when it stops rotating and preventing damage to the isolation shaft 7 caused by excessive rotation of the isolation shaft 7.

[0044] Working principle: Based on the Internet of Things remote control technology, when the disconnecting switch 5 needs to be in the closed state, the external control unit controls the servo motor 31 to start. Through the cooperation of the main gear 32 and the driven gear 33, the isolation shaft 7 rotates. At this time, the transmission frame 41 rotates, the guide rod 423 contracts, and the spring 424 continues to be compressed for energy storage. When the transmission frame 41 rotates to be in the same straight line as the guide rod 423, the spring 424 will release energy and squeeze the transmission frame 41 sideways, thereby assisting the transmission frame 41 to rotate until the protrusion 411 on the transmission frame 41 is blocked by the limit post 43. At the same time, the cam 61 slowly approaches the microswitch one 62 until it touches the microswitch one 62, so that the microswitch one 62 transmits a signal to the external control unit to control the servo motor 31 to stop running. At this time, the disconnecting switch 5 is in the closed state; when the disconnecting switch 5 needs to be in the open state, the external control unit controls the servo motor 31 to rotate in the reverse direction, so that the isolation shaft 7 rotates in the reverse direction and the transmission frame 41 rotates in the reverse direction. When the transmission frame 41 rotates to be in the same straight line as the guide rod 423, the spring 424 will release energy and press the transmission frame 41 downward, thereby assisting the transmission frame 41 to rotate until the protrusion 411 on the transmission frame 41 is blocked by another limit post 43. At the same time, the cam 61 moves away from the microswitch one 62 and slowly approaches the microswitch two 63 until it touches the microswitch two 63, so that the microswitch two 63 transmits a signal to the external control unit to control the servo motor 31 to stop running. At this time, the disconnecting switch 5 is in the open state.

[0045] The above-mentioned external control unit can be a mobile phone APP or a computer control terminal.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
