Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of internet of things circuit breaker, especially relates to a internet of things circuit breaker state feedback system. BACKGROUND

[0002] With the rapid development of internet of things technology, as an intelligent power equipment, internet of things circuit breaker has been widely used in many fields. Through remote control equipment such as mobile phone APP, computer application software, portable equipment, users can easily realize the closing and opening operation of internet of things circuit breaker, which greatly improves the convenience and efficiency of power management and control.

[0003] However, in the current internet of things circuit breaker remote control system, there is a common technical problem that the state displayed on the control equipment terminal may not be consistent with the actual state of the internet of things circuit breaker. Specifically, when the user clicks the closing or opening button on the control equipment terminal (such as mobile phone APP), the system usually indicates the current state of the circuit breaker through preset picture switching. Although this feedback mechanism based on user operation is simple and intuitive, it has significant limitations.

[0004] On the one hand, when the internet of things circuit breaker changes state due to mechanical failure, line protection action or manual operation, etc., these changes cannot be captured and fed back to the control equipment terminal in real time by the remote control system. This means that even if the actual state of the circuit breaker has changed, the state picture displayed on the control equipment terminal remains the same, and cannot truly reflect the current state of the circuit breaker; on the other hand, due to this inconsistency, engineering control personnel may make decisions and operations based on false information, which may cause electrical safety accidents. For example, when the circuit breaker automatically opens due to failure, if the control equipment terminal still displays the closing state, the engineering control personnel may misjudge that the circuit breaker is still in working state and try to perform further closing operation, which may cause short circuit, overload and other electrical faults, and even cause fire and other disastrous consequences in serious cases.

[0005] Therefore, how to provide an internet of things circuit breaker state feedback system that can capture and feed back the real state of the internet of things circuit breaker in real time is a technical problem that needs to be solved by those skilled in the art at present.

[0022] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort fall within the scope of protection of the present application.

[0023] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail in combination with the accompanying drawings and specific implementation.

[0024] Referring to Figure 1 The circuit breaker state feedback system of the Internet of Things provided by the present application comprises a shell 1, an inner wall of which is provided with a mounting groove; a micro switch 2 arranged in the mounting groove, the micro switch 2 being signal-connected with a controller, and the controller being signal-connected with a terminal device; an operating member rotationally connected with the inner wall of the shell 1, the operating member being provided with a rotating block 3, and the operating member having a working position and an initial position; when the operating member is in the working position, the rotating block 3 abuts against a contact piece of the micro switch 2, the micro switch 2 sends a closing signal to the controller; and when the operating member is in the initial position, the rotating block 3 is away from the contact piece of the micro switch 2, and the micro switch 2 sends an opening signal to the controller.

[0025] Specifically, the micro switch 2 is installed in the mounting groove in the shell 1, and is in signal connection with the controller. The micro switch 2 has a sensitive contact piece capable of sensing the action of external mechanical force and converting it into an electrical signal. When the contact piece is abutted by an external object, the micro switch 2 sends a corresponding signal to the controller. The controller, as a core processing unit, is in signal connection with the micro switch 2 and a terminal device (such as a mobile phone APP, a computer application software, etc.). The controller is responsible for receiving the signal sent by the micro switch 2 and sending a corresponding state feedback to the terminal device according to the signal content.

[0026] The operating member is rotationally connected to the inner wall of the shell 1 and can rotate by a certain angle relative to the shell 1, that is, the closing and opening of the Internet of Things circuit breaker is realized by the rotation of the operating member. The operating member is provided with a rotating block 3.

[0027] When the operating member is rotated to the working position (i.e., the Internet of Things circuit breaker is in the closed state), the rotating block 3 abuts against the contact piece of the micro switch 2, so that the micro switch 2 is activated and sends a closing signal to the controller. At this time, the controller sends the closing signal to the terminal device, and the terminal device displays that the circuit breaker is in the closed state.

[0028] When the operating member is rotated to the initial position (i.e., the Internet of Things circuit breaker is in the open state), the rotating block 3 is away from the contact piece of the micro switch 2, the micro switch 2 remains in the inactivated state and sends an opening signal to the controller, and the controller sends the opening signal to the terminal device. The terminal device displays that the circuit breaker is in the open state.

[0029] Through the state feedback system of the Internet of Things circuit breaker provided in the present application, the real state of the circuit breaker can be captured and fed back to the control device terminal in real time. When the state of the circuit breaker changes due to mechanical failure, line protection action or manual operation, etc., the operating member will rotate, driving the rotating block 3 to contact or separate from the contact piece of the micro switch 2, thereby triggering the micro switch 2 to send a corresponding signal to the controller. The controller then forwards the signal to the terminal device, realizing real-time updating and display of the state. Therefore, the state feedback system of the Internet of Things circuit breaker provided in the present application not only improves the reliability and safety of the remote control system of the Internet of Things circuit breaker, but also avoids the risk of misoperation caused by inconsistent states.

[0030] Specifically, the rotation of the operating member to realize the closing and opening of the Internet of Things circuit breaker is a direct use of the existing mature technology, which will not be described here.

[0031] On the basis of the above embodiment, the operating member comprises a connecting rod 4 and an operating handle (not shown in the figure), the first end of the connecting rod 4 is connected with the operating handle, the user controls the state of the circuit breaker by rotating the operating handle, the second end is rotatably connected with the inner wall of the shell 1, the rotating block 3 is connected to the outer peripheral surface of the second end of the connecting rod 4, when the operating handle is rotated, the connecting rod 4 drives the rotating block 3 to approach or move away from the contact of the micro switch 2.

[0032] Specifically, the first end of the connecting rod 4 is connected with the operating handle, the second end of the connecting rod 4 is rotatably connected with the inner wall of the shell 1, which ensures that the rotation of the operating handle can drive the connecting rod 4 to rotate,

[0033] When the operating handle is rotated, the connecting rod 4 will rotate, and the rotating block 3 will rotate with the connecting rod 4 to approach or move away from the contact of the micro switch 2.

[0034] Close operation:

[0035] The user holds the operating handle and rotates it clockwise to the closed position;

[0036] The connecting rod 4 rotates, and the rotating block 3 rotates clockwise with the connecting rod 4, so that it approaches and contacts the contact of the micro switch 2;

[0037] The micro switch 2 is activated and sends a closing signal to the controller;

[0038] After receiving the signal, the controller sends it to the terminal device to update the display of the state of the circuit breaker.

[0039] Open operation:

[0040] The user rotates the operating handle counterclockwise from the closed position to the open position;

[0041] The connecting rod 4 rotates counterclockwise, and the rotating block 3 rotates counterclockwise with the connecting rod 4, so that it moves away from the contact of the micro switch 2;

[0042] The micro switch 2 remains in an inactive state and sends an opening signal to the controller;

[0043] After receiving the signal, the controller also sends it to the terminal device to update the display of the state of the circuit breaker.

[0044] On the basis of the above embodiment, the inner wall of the shell 1 is provided with a bearing, and the second end of the connecting rod 4 is connected with the bearing.

[0045] Specifically, the second end of the connecting rod 4 is connected with the inner ring of the bearing, which can ensure that the connecting rod 4 rotates smoothly and reliably, and the bearing is accurately installed at a predetermined position on the inner wall of the shell 1, and through reasonable layout, it can ensure that the connecting rod 4 can smoothly drive the rotating block 3 to approach or move away from the contact of the micro switch 2 during rotation.

[0046] On the basis of the above-mentioned embodiments, referring to Figure 1 、 Figure 2 The connecting rod 4 is a triangular prism, and the rotating block 3 is provided with a triangular hole 5 matched with the triangular prism.

[0047] That is, the second end (i.e., the end away from the operating handle) of the connecting rod 4 can be inserted into the triangular hole 5 of the rotating block 3 and fixed by interference fit to ensure that the connection between the two is both firm and reliable. The precise matching of the triangular hole 5 with the triangular prism connecting rod 4 can ensure the synchronization and stability of the two during rotation.

[0048] On the basis of the above-mentioned embodiments, the inner wall of the shell 1 is provided with an arc-shaped groove 6 communicating with the mounting groove, and the end of the rotating block 3 away from the connecting rod 4 is provided with a limiting protrusion 7 which can be slidably matched with the arc-shaped groove 6.

[0049] Specifically, on the inner wall of the shell 1, an arc-shaped groove 6 communicating with the mounting groove is provided. The main function of the arc-shaped groove 6 is to serve as a guide and limiting mechanism for the movement of the rotating block 3.

[0050] A limiting protrusion 7 is provided at the end of the rotating block 3 away from the connecting rod 4. The limiting protrusion 7 is used to limit the movement range of the rotating block 3 and ensure that it can maintain a stable trajectory during movement. When the rotating block 3 is rotated under the driving of the connecting rod 4, the limiting protrusion 7 will slide in the arc-shaped groove 6, thereby guiding the rotating block 3 to approach or move away from the contact of the micro switch.

[0051] When the user rotates the connecting rod 4 by operating the handle, the connecting rod 4 will drive the rotating block 3 to rotate together. Due to the close fit of the limiting protrusion 7 and the arc-shaped groove 6, the rotating block 3 will move along the trajectory of the arc-shaped groove 6.

[0052] Specifically, the micro switch 2, the controller, and the terminal device are all connected and communicated through wireless signals, that is, the micro switch 2 will send corresponding signals to the controller when it is activated or not activated. The signals are transmitted wirelessly, avoiding the wiring complexity and maintenance cost brought by traditional wired connection.

[0053] The micro switch 2, the controller, and the terminal device need to follow relevant communication protocols, which can include wireless communication technology standards such as Bluetooth Low Energy, Zigbee, LoRaWAN, etc.

[0054] It should be noted that in the present specification, relational terms such as first and second are used only to distinguish one entity from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities.

[0055] The principle and implementation mode of the present application are described by using specific examples in the present application, and the above examples are only used for helping to understand the method and core idea of the present application. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principle of the present application, and these improvements and modifications also fall within the protection scope of the present application.
