Description

Technical Field

[0001] This invention relates to the field of power sensor technology, and in particular to a flexible shaft magnetic induction sensor device. Background Technology

[0002] Various transfer switches and disconnectors are widely used in power supply systems. To intelligently detect the switching status of transfer switches or disconnectors, a variety of magnetic induction sensor devices have emerged. However, for primary equipment with rotating shaft structures like transfer switches and disconnectors, internal space is often limited, generally lacking space and connection mechanisms for magnetic induction sensor devices. Therefore, most existing magnetic induction sensor devices are incompatible with currently used transfer switches and disconnectors, and their sensing angle and range are also limited. Furthermore, due to high design, manufacturing, and installation costs and long production cycles, existing magnetic induction sensor devices lack versatility and adaptability. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to provide a flexible shaft magnetic induction sensor device that solves the problems of limited versatility and adaptability of existing magnetic induction sensor devices.

[0004] To achieve this objective, the present invention adopts the following technical solution: a flexible shaft magnetic induction sensor device, comprising a flexible shaft, a sensor detection component, and a clamping component;

[0005] The sensor detection assembly is installed around the switch or knife switch that needs to be detected. The sensor detection assembly includes a detection rotating shaft and a detection receiving end, with the detection receiving end facing the detection transmitting end of the detection rotating shaft.

[0006] The first end of the flexible shaft is fixedly connected to the detection rotating shaft, the first end of the flexible shaft is coaxial with the detection rotating shaft, and the flexible shaft drives the detection rotating shaft to rotate.

[0007] The second end of the flexible shaft is connected to the clamp assembly; the clamp assembly is sleeved on the outer wall of the rotating shaft of the switch or knife switch to be tested, or the clamp assembly is connected in series to one end of the rotating shaft of the switch or knife switch to be tested along its length; the clamp assembly rotates with the rotating shaft; the second end of the flexible shaft is parallel to the rotating shaft, or the second end of the flexible shaft is coaxially installed with the rotating shaft.

[0008] It is worth noting that the flexible shaft magnetic induction sensor device also includes a first male connector and a first female connector, with one end of the first male connector and one end of the first female connector cooperating and connecting with each other;

[0009] The other end of the first male connector is inserted into the detection rotating shaft, and the first male connector is coaxially arranged with the detection rotating shaft. The other end of the first female connector is sleeved on the first end of the flexible shaft, and the first female connector is coaxially arranged with the first end of the flexible shaft.

[0010] Alternatively, the other end of the first connecting male component is coaxially arranged and connected to the first end of the flexible shaft, and the other end of the first connecting female component is coaxially arranged and connected to the detection rotation shaft.

[0011] Optionally, the flexible shaft magnetic induction sensor device further includes a second male connector and a second female connector, wherein one end of the second male connector and one end of the second female connector are connected to each other.

[0012] The other end of the second male connector is installed in the mounting groove of the clamp assembly, and the second male connector is parallel to or coaxial with the rotating shaft. The other end of the second female connector is sleeved on the second end of the flexible shaft, and the second female connector is coaxial with the second end of the flexible shaft.

[0013] Alternatively, the other end of the second connecting male component is coaxially arranged and connected to the second end of the flexible shaft, the other end of the second connecting female component is installed in the mounting groove of the clamp assembly, and the second connecting female component is parallel to the rotating shaft or coaxial with the rotating shaft.

[0014] Specifically, the clamp assembly includes a clamp body and a pressure plate, the pressure plate being detachably connected to the outer wall of the clamp body; the inner wall of the pressure plate faces the outer wall of the clamp body, the mounting groove is formed on the inner wall of the pressure plate, and / or the mounting groove is formed on the outer wall of the clamp body.

[0015] Preferably, the clamp assembly is divided into a first clamp and a second clamp, both of which are semi-circular structures. The first clamp and the second clamp are connected to each other and are sleeved on the outer wall of the rotating shaft.

[0016] It is worth noting that the detection transmitting end of the detection rotating shaft is a magnet, the detection receiving end is equipped with a reed switch, and the detection transmitting end is set on the side wall of the detection rotating shaft and rotates with the detection rotating shaft.

[0017] Optionally, the detection receiving end includes a first receiving end and a second receiving end, which are arranged around the detection rotation axis. When the switch or knife switch is in the open state, the first receiving end faces the detection transmitting end, and when the switch or knife switch is in the closed state, the second receiving end faces the detection transmitting end.

[0018] Specifically, the sensor detection assembly further includes an outer cover, and the detection rotating shaft and the detection receiving end are both disposed inside the outer cover;

[0019] The outer cover is provided with an arc-shaped groove, which is arranged around the detection rotation axis, and the center of the arc-shaped groove is located on the axis of the detection rotation axis;

[0020] The first receiving end and the second receiving end are slidably connected to the arc-shaped groove.

[0021] Preferably, the sensor detection assembly further includes a fixing screw, which passes through the first receiving end and / or the second receiving end and enters the arc-shaped groove, thereby fixing the first receiving end and / or the second receiving end to the arc-shaped groove.

[0022] It is worth noting that the outer cover has a cable opening, through which the communication cable passes and is electrically connected to the first receiving end and / or the second receiving end.

[0023] One of the above technical solutions has the following beneficial effects: In the flexible shaft magnetic induction sensor device, the flexible shaft can drive the detection rotation shaft of the sensor detection assembly, which is installed outside the switch or knife switch to be detected, to rotate. When the detection transmitter approaches the detection receiver, the detection receiver reacts by generating an electrical signal, thereby detecting the current state of the switch or knife switch. Since the sensor detection assembly can be installed outside the switch or knife switch to be detected, the sensing angle and range of the sensor detection assembly are not limited, and it is also convenient to install and maintain, thus improving its versatility and adaptability.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The following is combined Figures 1 to 5 This invention describes a flexible shaft magnetic induction sensor device according to an embodiment of the present invention, including a flexible shaft 1, a sensor detection component 2, and a clamping component 3;

[0037] The sensor detection assembly 2 is installed around the switch or knife switch that needs to be detected. The sensor detection assembly 2 includes a detection rotating shaft 21 and a detection receiving end 23. The detection receiving end 23 faces the detection transmitting end 22 of the detection rotating shaft 21.

[0038] The first end of the flexible shaft 1 is fixedly connected to the detection rotating shaft 21. The first end of the flexible shaft 1 is coaxially arranged with the detection rotating shaft 21, and the flexible shaft 1 drives the detection rotating shaft 21 to rotate.

[0039] The second end of the flexible shaft 1 is connected to the clamp assembly 3, such as Figure 1 , 4 The clamp assembly 3 shown in Figures 5 and 6 is sleeved on the outer wall of the rotating shaft 4 of the switch or knife switch to be tested, or as shown in Figures 6 and 7. Figure 7 The clamp assembly 3 shown is connected in series to one end of the length direction of the rotating shaft 4 of the switch or knife switch to be tested; the clamp assembly 3 rotates with the rotating shaft 4; as shown Figure 1 , 4 The second end of the flexible shaft 1 shown in Figures 5 and 6 is parallel to the rotation axis 4, or as shown in Figures 6 and 7. Figure 7 The second end of the flexible shaft 1 shown is coaxially mounted with the rotating shaft 4; in one embodiment, the clamping assembly 3 directly clamps the shaft core of the second end of the flexible shaft 1.

[0040] In the flexible shaft magnetic induction sensor device, the flexible shaft 1 drives the detection rotation shaft 21 of the sensor detection assembly 2, which is installed outside the switch or knife switch to be detected, to rotate. When the detection transmitter 22 approaches the detection receiver 23, the detection receiver 23 reacts by generating an electrical signal, thereby detecting the current state of the switch or knife switch. Since the sensor detection assembly 2 can be installed outside the switch or knife switch to be detected, the sensing angle and range of the sensor detection assembly 2 are not limited, and it is also convenient to install and maintain, thus improving its versatility and adaptability.

[0041] like Figure 1 , 4 As shown in Figures 5, 6, and 7, when the switch or knife switch is opened or closed, the rotating shaft 4 of the switch or knife switch rotates. The second end of the flexible shaft 1, which is clamped by the clamp assembly 3, swings and rotates with the rotating shaft 4. At the same time, the second end of the flexible shaft 1 flips relative to the stationary ground plane, thereby driving the first end of the flexible shaft 1 to rotate through the middle section of the flexible shaft 1, thus realizing the rotation of the flexible shaft 1. In this way, the first end of the flexible shaft 1 can drive the detection rotating shaft 21 to rotate.

[0042] In this embodiment, the core of the flexible shaft 1 is composed of a core wire and multiple layers of spring material wound around the core wire in both directions, thus forming a multi-strand steel wire with different outer diameters. In this embodiment, the flexible shaft 1 is installed close to the side of the sensor detection component 2, and the installation position and angle of the clamp component 3 are selected according to the rotation direction of the rotating shaft 4, so that the flexible shaft 1 can rotate freely with the rotating shaft 4 in a rotation space of about 100°. The flexible shaft 1 rotates on its own second end as it rotates around the rotating shaft 4, and moves naturally as one end of it moves. That is, the flexible shaft 1 will naturally change its spatial shape and move naturally like a steel wire rope. As long as the bending angle of the flexible shaft 1 in the air is not very small (such as a forced sharp bend), it will swing naturally, so there will be no phenomenon of the flexible shaft 1 becoming taut and pulling the sensor detection component 2.

[0043] In some embodiments, the flexible shaft magnetic induction sensor device further includes a first male connector 5 and a first female connector 6, one end of the first male connector 5 and one end of the first female connector 6 being mutually connected; the other end of the first male connector 5 is inserted into the detection rotating shaft 21, and the first male connector 5 is coaxially arranged with the detection rotating shaft 21; the other end of the first female connector 6 is sleeved on the first end of the flexible shaft 1, and the first female connector 6 is coaxially arranged with the first end of the flexible shaft 1; or the other end of the first male connector 5 is coaxially arranged and connected with the first end of the flexible shaft 1, and the other end of the first female connector 6 is coaxially arranged and connected with the detection rotating shaft 21.

[0044] like Figure 1 As shown, the first male connector 5 and the first female connector 6 facilitate the installation and disassembly of the flexible shaft 1 and the detection rotating shaft 21, thereby facilitating maintenance of the sensor detection assembly 2 by personnel. In this embodiment, both the first male connector 5 and the first female connector 6 are provided with corresponding through holes. After the first male connector 5 is inserted into the first female connector 6 and the through hole of the first female connector 6 is aligned with the through hole of the first male connector 5, the first female connector 6 and the first male connector 5 can be locked by passing the screw through both through holes simultaneously. Specifically, the first male connector 5 is a hexagonal male connector, and the first female connector 6 is a hexagonal female connector. The hexagonal structure of the hexagonal male and female connectors prevents rotation between them.

[0045] It is worth noting that the flexible shaft magnetic induction sensor device also includes a second male connector 7 and a second female connector 8. One end of the second male connector 7 and one end of the second female connector 8 are connected to each other. The other end of the second male connector 7 is installed in the mounting groove 31 of the clamp assembly 3, and the second male connector 7 is parallel to the rotating shaft 4 or coaxial with the rotating shaft 4. The other end of the second female connector 8 is sleeved on the second end of the flexible shaft 1, and the second female connector 8 is coaxial with the second end of the flexible shaft 1. Alternatively, the other end of the second male connector 7 is coaxial with and connected to the second end of the flexible shaft 1, and the other end of the second female connector 8 is installed in the mounting groove 31 of the clamp assembly 3, and the second female connector 8 is parallel to the rotating shaft 4 or coaxial with the rotating shaft 4.

[0046] like Figure 1 As shown, the second male connector 7 and the second female connector 8 facilitate the installation and disassembly of the flexible shaft 1 and the clamp assembly 3, thereby making it easier for workers to replace and maintain the flexible shaft 1 and the clamp assembly 3. In this embodiment, both the second male connector 7 and the second female connector 8 are provided with corresponding through holes. After the second male connector 7 is inserted into the second female connector 8 and the through hole of the second female connector 8 is aligned with the through hole of the second male connector 7, the second female connector 8 and the second male connector 7 can be locked by passing the screw through both through holes simultaneously. Specifically, the second male connector 7 is a hexagonal male connector, and the second female connector 8 is a hexagonal female connector. The hexagonal structure of the hexagonal male and female connectors prevents rotation between them.

[0047] Optionally, the clamp assembly 3 includes a clamp body 33 and a pressure plate 32, wherein the pressure plate 32 is detachably connected to the outer wall of the clamp body 33; the inner wall of the pressure plate faces the outer wall of the clamp body 33, and the mounting groove 31 is formed in the inner wall of the pressure plate 32, and / or the mounting groove 31 is formed in the outer wall of the clamp body 33. Figure 3As shown, in one embodiment, both the pressure plate 32 and the clamp body 33 have mounting grooves on their outer walls. After the pressure plate 32 is placed in the groove, the mounting groove 31 on the pressure plate 32 and the mounting groove 31 on the outer wall of the clamp body 33 are combined into a mounting hole, through which the other end of the second connecting male 7 or the other end of the second connecting female 8 can pass and connect. In this embodiment, the pressure plate 32 has a through hole, and the outer wall of the clamp body 33 has a screw hole corresponding to the through hole of the pressure plate 32. After aligning the through hole of the pressure plate 32 with the screw hole on the outer wall of the clamp body 33, the pressure plate 32 can be fixed to the outer wall of the clamp body 33 by a screw. Specifically, the outer wall of the clamp body 33 has a groove that is complementary in shape to the pressure plate 32. Placing the pressure plate 32 in the groove can restrict the swing of the pressure plate 32. In another embodiment, the mounting groove 31 is formed in the pressure plate 32, and the mounting groove 31 and the outer wall of the clamp body 33 form a mounting hole for the other end of the second connecting male 7 or the other end of the second connecting female 8 to pass through and connect. In another embodiment, the mounting groove 31 is formed in the outer wall of the clamp body 33, and the mounting groove 31 and the inner wall of the pressure plate 32 form a mounting hole for the other end of the second connecting male 7 or the other end of the second connecting female 8 to pass through and connect.

[0048] Preferably, the clamp assembly 3 is divided into a first clamp member 331 and a second clamp member 332. Both the first clamp member 331 and the second clamp member 332 have a semi-circular structure. The first clamp member 331 and the second clamp member 332 are connected to each other and sleeved on the outer wall of the rotating shaft 4. In use, firstly, the first clamp member 331 is sleeved on the rotating shaft 4, then the second clamp member 332 is sleeved on the rotating shaft 4, and the first clamp member 331 and the second clamp member 332 are symmetrically arranged about the rotating shaft 4. Finally, the first clamp member 331 and the second clamp member 332 are connected to install the clamp assembly 3 on the rotating shaft 4. In this embodiment, the first clamp member 331 and the second clamp member 332 have corresponding through holes. After aligning the through holes of the first clamp member 331 and the second clamp member 332, a screw is passed through and locked to fix the clamp assembly 3 to the rotating shaft 4.

[0049] In some embodiments, the detection transmitter 22 of the detection rotating shaft 21 is a magnet, and the detection receiver 23 is equipped with a reed switch. The detection transmitter 22 is disposed on the side wall of the detection rotating shaft 21 and rotates with the detection rotating shaft 21. The detection rotating shaft 21 rotates under the drive of the flexible shaft 1, which in turn drives the detection transmitter 22 to rotate. The detection transmitter 22 rotates about the central axis of the detection rotating shaft 21. When the detection transmitter 22 of the detection rotating shaft 21 approaches the detection receiver 23, the magnet structure of the detection transmitter 22 generates a magnetic field with the reed switch of the detection receiver 23. The reed switch actuates to generate an electrical signal, which can identify the open / closed state of the switch or knife switch.

[0050] It is worth noting that the detection receiver 23 includes a first receiver 231 and a second receiver 232, which are arranged around the detection rotation axis 21. When the switch or knife switch is in the open state, the first receiver 231 faces the detection transmitter 22; when the switch or knife switch is in the closed state, the second receiver 232 faces the detection transmitter 22. Figure 2 As shown, in this embodiment, the first receiving end 231 is set at the position to which the detection transmitting end 22 rotates when the switch or knife switch is in the open state, and the second receiving end 232 is set at the position to which the detection transmitting end 22 rotates when the switch or knife switch is in the closed state. In this way, the open and closed states of the switch or knife switch can be obtained through magnetic induction.

[0051] Optionally, the sensor detection assembly 2 further includes an outer cover 24, within which the detection rotation shaft 21 and the detection receiving end 23 are both disposed. The outer cover 24 is provided with an arc-shaped groove 241, which surrounds the detection rotation shaft 21, with its center located on the axis of the detection rotation shaft 21. Thus, the distance from the arc-shaped groove 241 to the axis of the detection rotation shaft 21 is equidistant everywhere. The first receiving end 231 and the second receiving end 232 are slidably connected to the arc-shaped groove 241. By sliding the first receiving end 231 and / or the second receiving end 232 along the arc-shaped groove 241, the relative position between the first receiving end 231 and / or the second receiving end 232 and the detection transmitting end 22 can be adjusted, thereby adapting to the opening and closing strokes of different switching switches or knife switches. In this embodiment, the sensor detection assembly 2 further includes a cover plate, which is used to cover the outer cover 24, thereby protecting the detection rotating shaft 21 and the detection receiving end 23 located inside the outer cover 24.

[0052] Specifically, the sensor detection assembly 2 further includes a fixing screw 25, which passes through the first receiving end 231 and / or the second receiving end 232 and enters the arc-shaped sliding groove 241, fixing the first receiving end 231 and / or the second receiving end 232 to the arc-shaped sliding groove 241. Loosening the fixing screw 25 allows the first receiving end 231 and / or the second receiving end 232 to slide along the arc-shaped sliding groove 241, adjusting the relative position between the first receiving end 231 and / or the second receiving end 232 and the detection transmitting end 22. Tightening the fixing screw 25 fixes the first receiving end 231 and / or the second receiving end 232 to the arc-shaped sliding groove 241, preventing inaccurate detection due to the first receiving end 231 and / or the second receiving end 232 deviating from its original position caused by shaking.

[0053] Preferably, the outer casing 24 has cable openings, through which the communication cable 26 passes and is electrically connected to the first receiving end 231 and / or the second receiving end 232. The communication cable 26 is used to transmit signals generated by the first receiving end 231 and / or the second receiving end 232 reflecting the opening and closing of a switching switch or knife switch to the host computer. In this embodiment, the outer casing 24 has multiple cable openings. In actual installation, the communication cable 26 can be inserted through the cable opening closest to the first receiving end 231 and / or the second receiving end 232, thus facilitating wiring.
