[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0033] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Existing data acquisition and monitoring devices for sulfur hexafluoride (SF6) detection can basically meet daily usage needs, but there are still some shortcomings. First, most of these devices are fixedly installed in detection boxes, making installation and disassembly cumbersome and increasing maintenance costs. Second, most existing SF6 data acquisition and monitoring devices use spot welding for electrical connections, which can easily cause the welds to detach during use due to vibrations, affecting the stability of data transmission. Third, these devices have poor impact resistance, making them susceptible to sensor damage from impacts, thus affecting their lifespan and the monitoring effectiveness of high-voltage substations, making it difficult to accurately predict defects in high-voltage substations.

[0038] refer to Figures 1-5 This embodiment provides a data acquisition and monitoring device, including a sensor 1, a cable box 2, and a buffer mechanism. The snap-fit ​​connection between the sensor 1 and the cable box 2 allows for quick connection or disconnection; the insertion hole 11 and insertion assembly 21 ensure a secure connection between the sensor 1 and the cable box 2, preventing vibration interference; finally, the buffer mechanism connects to other devices requiring monitoring. When the sensor 1 encounters vibration or impact on other devices, the buffer mechanism effectively absorbs the vibration and impact, reducing damage to the data acquisition and monitoring device and extending its lifespan, thus supporting data acquisition and substation smart gateway applications within substations.

[0039] Sensor 1 includes a plug hole 11; cable box 2 is snapped into one side of sensor 1, cable box 2 includes a plug assembly 21, plug assembly 21 can be inserted into plug hole 11 to make electrical connection between sensor 1 and cable box 2, the outer surface of plug assembly 21 can elastically abut against the inner surface of plug hole 11; buffer mechanism includes a first buffer assembly 31 and a second buffer assembly 32, the first buffer assembly 31 is connected to the other side of cable box 2, and the second buffer assembly 32 is elastically connected to the first buffer assembly 31.

[0040] The snap-fit ​​connection between sensor 1 and cable box 2 on one side allows for quick installation and removal of sensor 1 from cable box 2, reducing the maintenance cost of the data acquisition and monitoring device. Because the outer surface of the plug-in component 21 can elastically abut against the inner surface of the plug-in hole 11, it ensures that the outer surface of the plug-in component 21 remains in contact with the inner surface of the plug-in hole 11 during vibration or shaking, guaranteeing a stable electrical connection. A buffer mechanism reduces damage to sensor 1 from impacts. The first buffer component 31 is connected to cable box 2, and the second buffer component 32 is used to connect other equipment. The first elastic component 31 and the second elastic component 32 are elastically connected. When the equipment vibrates or is impacted, the first elastic component 31 and the second elastic component 32 can effectively absorb the vibration and impact, preventing damage to the internal components of the data acquisition and monitoring device, extending the service life of the data acquisition and monitoring device, ensuring the monitoring effect of high-voltage substation equipment, and enabling timely and accurate early warning of defects in high-voltage substation equipment.

[0041] Furthermore, the sensor 1 also includes a display screen 16, which is located on the side of the sensor 1 away from the cable box 2. The display screen 16 can display parameters such as gas density and moisture content, making it convenient for maintenance personnel to view.

[0042] Specifically, the sensor 1 also includes a snap-fit ​​component 15, and the cable box 2 also includes a snap-fit ​​base 26. The snap-fit ​​component 15 can snap onto the snap-fit ​​base 26, so that the sensor 1 can snap onto the cable box 2, and the connection and disassembly of the data acquisition and monitoring device and the cable box 2 are convenient and quick, reducing the maintenance difficulty of the data acquisition and monitoring device.

[0043] Specifically, the plug-in assembly 21 includes a plug post 211, a connecting piece 212, and a first elastic member 213. The connecting piece 212 is disposed around the plug post 211, and the first elastic member 213 is disposed between the connecting piece 212 and the plug post 211. The side of the connecting piece 212 away from the plug post 211 can abut against the wall of the plug hole 11. By providing the first elastic member 213 between the connecting piece 212 and the plug post 211, there is elasticity between the connecting piece 212 and the plug post 211. When the plug post 211 drives the connecting piece 212 to be inserted into the plug hole 11, the connecting piece 212 will be squeezed by the wall of the plug hole 11 towards the plug post 211. At this time, the first elastic member 213 gives the connecting piece 212 a force away from the plug post 211, so that the connecting piece 212 can abut tightly against the wall of the plug hole 11. Moreover, due to the presence of the first elastic element 213, when vibration or shaking occurs, the first elastic element 213 can absorb energy, so that the connecting piece 212 can still tightly abut against the wall of the insertion hole 11 under vibration, ensuring a reliable electrical connection between the sensor 1 and the cable box 2.

[0044] The type of the first elastic element 213 is not limited here. In this embodiment, the first elastic element 213 is a compression spring, which ensures that the connecting piece 212 provides force against the wall of the connecting hole when it is inserted into the insertion hole 11. In other embodiments, the first elastic element 213 can also be rubber or the like. It should be ensured that when the connecting piece 212 is not inserted into the insertion hole 11 and is not subjected to other external forces, the distance from the connecting piece 212 to the insertion post 211 is greater than the radius of the insertion hole 11.

[0045] There is no limitation on the number of connecting pieces 212. In this embodiment, three connecting pieces 212 are provided to ensure the stability of the connecting pieces 212 during movement. In other embodiments, the number of connecting pieces 212 can be specifically set as needed.

[0046] The connecting pieces 212 are arc-shaped and can form a circle between each other, facilitating the insertion of the connecting pieces 212 and their fit against the inner wall of the insertion hole 11. Furthermore, the end of the connecting pieces 212 facing the sensor 1 has an angle, so that the diameter of the circle formed by the connecting pieces 212 near the sensor 1 is smaller than the diameter of the insertion hole 11, making it easier for the operator to insert the insertion assembly 21 into the insertion hole 11.

[0047] Specifically, the plug-in post 211 is provided with a guide hole 2111, and the connecting piece 212 is provided with a guide post 2121. The guide post 2121 can be slidably inserted into the guide hole 2111. The first elastic member 213 is sleeved on the periphery of the guide post 2121. The connecting piece 212 can move along the axis of the guide post 2121. The guide post 2121 and the guide hole 2111 guide the movement of the connecting piece 212, ensuring the stability of the movement of the connecting piece 212. This further ensures the fit between the outer surface of the connecting piece 212 and the wall of the plug-in hole 11 after the plug-in assembly 21 is inserted into the plug-in hole 11.

[0048] Specifically, the cable box 2 is provided with a connecting groove 22, the plug-in assembly 21 is provided in the connecting groove 22, the sensor 1 is provided with a connecting frame 12, the plug-in hole 11 is provided in the connecting frame 12, the connecting frame 12 can be embedded in the connecting groove 22, a sealing element 13 is provided between the outer peripheral surface of the connecting frame 12 and the inner peripheral surface of the connecting groove 22, the connecting frame 12 and the connecting groove 22 can form a sealed space, ensuring that the plug-in assembly 21 and the plug-in hole 11 are in the sealed space, preventing dust or moisture from entering and affecting the electrical connection between the sensor 1 and the cable box 2.

[0049] Furthermore, sensor 1 is provided with a limiting post 14, and cable box 2 is provided with a limiting hole 23. The limiting post 14 can be inserted into the limiting hole 23 to further limit the connection between sensor 1 and cable box 2, ensuring a reliable connection and facilitating the operator to insert the device.

[0050] There is no limitation on the number of limiting holes 23 and limiting posts 14. In this embodiment, there are two limiting holes 23 and two limiting posts 14. The two limiting holes 23 are respectively located on both sides of the cable box 2, and the two limiting posts 14 are respectively located on both sides of the connecting frame 12 to ensure a firm connection.

[0051] The first buffer assembly 31 includes a first vertical plate 311 and a first horizontal plate 312, and the second buffer assembly 32 includes a second vertical plate 321 and a second horizontal plate 322. A second elastic element 33 is provided between the first vertical plate 311 and the second vertical plate 321, and a third elastic element 34 is provided between the first horizontal plate 312 and the second horizontal plate 322. By vertically arranging the first horizontal plate 312 and the second horizontal plate 322 with the first vertical plate 311 and the second vertical plate 321, the first elastic element 313 and the second elastic element 33 can remain stable, better absorb vibration and impact, ensure the buffering effect of the buffer mechanism, and avoid damage to the data acquisition and monitoring device under vibration or impact.

[0052] There is no limitation on the types of the second elastic element 33 and the third elastic element 34. In this embodiment, the second elastic element 33 and the third elastic element 34 are both compression springs. In other embodiments, the second elastic element 33 and the third elastic element 34 may also be rubber.

[0053] Specifically, both ends of the second horizontal plate 322 are provided with limiting plates 3221, forming a limiting space between the two limiting plates 3221. The first horizontal plate 312 is disposed within the limiting space, with each end of the first horizontal plate 312 abutting against one of the limiting plates 3221. A buffer member 35 is provided between the first horizontal plate 312 and the limiting plates 3221, reducing the relative movement between the first buffer assembly 31 and the second buffer assembly 32 in other directions, ensuring the stability of the connection, and preventing damage to the connection between the first buffer assembly 31 and the second buffer assembly 32 during vibration. The buffer member 35 can reduce lateral vibration and prevent wear between the first horizontal plate 312 and the limiting plates 3221.

[0054] Furthermore, the second horizontal plate 322 is provided with a limiting rod 3222, one end of which can abut against the first horizontal plate 312. Multiple third elastic elements 34 are provided, and the multiple elastic elements are evenly spaced around the limiting rod 3222 to limit the compression stroke of the third elastic element 34, so as to avoid excessive compression that could lead to fatigue failure of the third elastic element 34 or damage to the connection between the third elastic element 34 and other components.

[0055] This embodiment also provides a high-voltage substation equipment, including the equipment body and the aforementioned data acquisition and monitoring device. The equipment body is connected to the second buffer component 32. When the high-voltage substation equipment is subjected to impact or vibration, the buffer mechanism can absorb the vibration and impact, stabilizing the connection between the data acquisition and monitoring device and the cable box 2 and extending the service life of the data acquisition and monitoring device, thus ensuring the accuracy of the data acquisition and monitoring device's detection. This ensures that the data acquisition and monitoring device can accurately detect sulfur hexafluoride within the high-voltage substation equipment, ensuring real-time monitoring of the high-voltage substation equipment, enabling timely and accurate early warning of defects in the high-voltage substation equipment, ensuring the safe operation of the high-voltage substation equipment, protecting the personal safety of personnel, and supporting the application of data acquisition and substation intelligent gateways within the substation.
