Description

Technical Field

[0001] This application relates to the field of image monitoring equipment technology, and in particular to a self-powered monitoring device. Background Technology

[0002] The CT-powered image monitoring device is a device that uses current transformer (CT) technology to power image monitoring equipment, enabling real-time monitoring of power lines and other scenarios.

[0003] In complex and harsh environments, traditional power supply methods often struggle to operate stably or even provide power to monitoring equipment. In such cases, current-driven power supply technology, with its unique working mechanism and significant advantages, becomes a crucial power supply method to ensure the continuous operation of monitoring equipment.

[0004] Existing self-powered monitoring devices, such as a partial discharge monitoring device, system and method for power extraction from a CT in an overhead distribution line (CN119355458A), monitor by fixing the cable inside the CT's electromagnetic induction device. However, since the magnetic induction through-hole for fixing the cable is fixed, this structure can only be used for monitoring one type of cable, resulting in poor versatility. Furthermore, the disassembly and assembly of the cable and the CT's electromagnetic induction device are inconvenient. Utility Model Content

[0005] The purpose of this application is to provide a self-powered monitoring device that can be used to monitor different types of cables.

[0006] To achieve the above objectives, this utility model provides a self-powered monitoring device, including a monitoring device body and a CT magnetic sensing mechanism disposed on the monitoring device body. The CT magnetic sensing mechanism includes a lower magnetic support and an upper magnetic support connected to the lower magnetic support.

[0007] One end of the upper magnetic support is rotatably connected to the lower magnetic support via an automatic locking assembly, and a magnetic induction through hole is formed between the upper and lower magnetic support to allow cables to pass through. The upper magnetic support is flipped by the automatic locking assembly, thereby closing or opening the magnetic induction through hole to allow cables to enter the magnetic induction through hole or to prevent cables from coming out of the magnetic induction through hole.

[0008] To achieve automatic locking between the upper and lower magnetic support, the automatic locking assembly includes a rotating shaft and a locking torsion spring. The rotating shaft is rotatably connected to the lower magnetic support, one end of the upper magnetic support is fixed to the rotating shaft, and the locking torsion spring is fixed to the rotating shaft. One end of the locking torsion spring extends along the outer wall of the upper magnetic support and can apply downward pressure to the upper magnetic support.

[0009] To accommodate different types of cable clamping, the CT magnetic sensing mechanism also includes an automatic clamping component capable of clamping the cable within the magnetic sensing through hole. The automatic clamping component includes a set of opposing clamping torsion springs. One end of the clamping torsion spring is rotatably connected to the lower magnetic support via a pin, and the other end of the clamping torsion spring extends into the magnetic sensing through hole to form a clamping part capable of clamping the cable.

[0010] To achieve automatic clamping, the clamping part of one of the clamping torsion springs can apply downward pressure to the cable, and the clamping part of the other clamping torsion spring can apply upward pressure to the cable. The two clamping parts can keep the cable at the axial position of the magnetic induction through hole.

[0011] To facilitate connection of the monitoring device with other equipment, the bottom of the main body of the monitoring device has several interfaces.

[0012] To ensure power supply, the outer wall of the main body of the monitoring device has several solar panels.

[0013] In summary, this utility model has the following beneficial effects: the self-powered monitoring device, through the special design of the lower magnetic support and the upper magnetic support, can adapt to the monitoring of cables of different sizes or models, while improving the efficiency of cable assembly and disassembly, and is more convenient to use.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "side", "end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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 this utility model.

[0019] like Figure 1-3 The self-powered monitoring device shown includes a monitoring device body 1 and a CT magnetic sensing mechanism disposed on the top of the monitoring device body 1. The bottom of the monitoring device body 1 has several interfaces 5, and the outer wall of the monitoring device body 1 has several solar panels 4. The CT magnetic sensing mechanism includes a lower magnetic support 2 and an upper magnetic support 3 connected to the lower magnetic support 2. A magnetic induction through hole is formed between the upper magnetic support 3 and the lower magnetic support 2, which allows cables to pass through. The upper magnetic support 3 adopts a flip-top structure.

[0020] One end of the upper magnetic support 3 is rotatably connected to the lower magnetic support 2 through an automatic locking component. The upper magnetic support 3 is flipped through the automatic locking component, thereby closing or opening the magnetic induction through hole to allow the cable to enter the magnetic induction through hole or to prevent the cable from coming out of the magnetic induction through hole.

[0021] Specifically, the automatic locking assembly includes a rotating shaft 6 and a locking torsion spring 7. The rotating shaft 6 is rotatably connected to one side of the lower magnetic support 2. One end of the upper magnetic support 3 is fixed to the rotating shaft 6. The upper magnetic support 3 can be flipped through the rotating shaft 6. The locking torsion spring 7 is fixed on the rotating shaft 6. One end of the locking torsion spring 7 extends along the outer wall of the lower magnetic support 2, and the other end extends along the top outer wall of the upper magnetic support 3, forming a rectangular pressure part 8. The pressure part 8 can apply a downward pressure to the upper magnetic support 3, so that the upper magnetic support 3 can automatically close with the lower magnetic support 2.

[0022] In addition, the CT electromagnetic sensing mechanism also includes an automatic clamping assembly capable of clamping the cable within the magnetic induction through-hole. Specifically, the automatic clamping assembly includes a set of clamping torsion springs 10 arranged opposite to each other. One end of the clamping torsion spring 10 is connected to the lower magnetic induction support 2 via a pin 9, and the other end of the clamping torsion spring 10 extends into the magnetic induction through-hole and forms a clamping part 11 capable of clamping the cable. The clamping part 11 has a rectangular structure. The clamping part 11 of one clamping torsion spring 10 can apply downward pressure to the cable, and the clamping part 11 of the other clamping torsion spring 10 can apply upward pressure to the cable. The two clamping parts 11 can keep the cable at the axial position of the magnetic induction through-hole.

[0023] In use, the operator applies a certain force to the upper magnetic support 3 using an auxiliary tool, flipping the upper magnetic support 3 upwards. The high-voltage cable to be monitored can then enter the magnetic induction through hole. At the same time, the auxiliary tool rotates the two clamping parts 11 upwards or downwards, so that the cable enters between the two clamping parts 11. After the operator removes the auxiliary tool, due to the restoring torque of the locking torsion spring 7 and the clamping torsion spring 10, the two clamping parts 11 can clamp the cable. At the same time, the upper magnetic support 3 and the lower magnetic support 2 automatically close, and the entire self-powered monitoring device is suspended on the cable. After power is supplied, it can be monitored.

[0024] The self-powered monitoring device's acquisition unit automatically senses high-voltage current and generates current through magnets and coils. After rectification and filtering, it is converted into DC power to supply power to the base. Through the 485 interface, the transmission board transmits the front-end monitoring images to the back-end platform. The device uses a combination of self-powered power lines and solar panels for power, making it more reliable. The device is also equipped with lithium iron phosphate batteries, which can be charged to ensure stable current. It uses nanocrystalline CT magnetic core material, making the device lighter than those on the market, and it can draw power from the ground when the current is less than 5A.

[0025] This self-powered monitoring device has a wide range of applications. It is not only suitable for conventional medium and low voltage transmission lines, but also for underground mines, tunnels and other places with narrow spaces, damp and dark environments. It can provide stable power to the monitoring equipment, ensuring that the monitoring system can operate normally in harsh environments and achieve continuous and effective monitoring of key areas.

[0026] In the description of the embodiments of this utility model, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," "set up," "equipped with," etc., 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 utility model based on the specific circumstances.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
