Description

Technical Field

[0001] This utility model relates to the technical field of transformers, and in particular to an electrical component support mechanism and a gas monitoring device in transformer oil. Background Technology

[0002] In power systems, the operational stability and safety of electrical equipment directly affect the normal operation of the power grid. Especially during the operation and maintenance of critical equipment such as transformers, online monitoring of dissolved gases in oil has become a crucial means of assessing the internal insulation status and potential faults of the equipment. Transformer oil gas monitoring devices, as the core equipment for achieving this function, are typically integrated into substations or field monitoring systems. They contain various precision electrical components, such as sensor modules, data acquisition units, and control circuit boards. These components not only require high installation accuracy but also demand high ease of operation during routine maintenance, commissioning, and replacement.

[0003] Currently, traditional methods of installing electrical components mostly involve using fixed brackets or direct screws to fix them to the internal structure of the equipment. However, during assembly or maintenance, these components are usually located deep inside the equipment, where operating space is limited, leading to difficulties in installation and disassembly and affecting work efficiency. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this utility model provides an electrical component support mechanism and a gas monitoring device in transformer oil.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an electrical component support mechanism, comprising:

[0007] Two guide slots are installed in parallel inside the detection device;

[0008] Both support frames are configured as a grid structure, and the grid structure includes a short shaft and a long shaft. Movable parts are rotatably mounted at both ends of the long shaft, and the movable parts at both ends of the long shaft are slidably mounted in two guide grooves.

[0009] The connector is rotatably mounted to two short shafts, and the connector is provided with a fixing plate for mounting electrical components;

[0010] Each of the two guide slots is equipped with a positioning mechanism, which is used to lock the connection position between the moving part and the guide slot.

[0011] The limiting mechanism is installed in conjunction with the detection device and the connecting parts. The limiting mechanism is used to limit the movement trajectory of the fixed plate.

[0012] Furthermore, the positioning mechanism includes:

[0013] Two mounting parts are symmetrically mounted on the guide groove. A positioning pin is slidably provided inside the mounting part. The positioning pin is connected to the teeth provided on the moving part. An extension is provided on the positioning pin and passes through the inner hole of the mounting part.

[0014] The first spring is mounted on the positioning pin, and the other end of the first spring is connected to the inner groove of the mounting part.

[0015] The transmission mechanism is connected to two extensions on the same guide groove, which is used to connect and disconnect the locating pin from the moving part.

[0016] Furthermore, the transmission mechanism includes:

[0017] A connecting beam is fixedly connected to two extension members. A transmission beam is provided on the connecting beam, and the transmission beam and the connecting beam form a T-shaped structure.

[0018] The drive block is installed at the end of the transmission beam and has an anti-slip structure.

[0019] Furthermore, the two positioning mechanisms on the two guide slots are used to lock the position of the moving parts when the fixed plate is unfolded, and to lock the position of the moving parts when the fixed plate is retracted.

[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 5 As shown;

[0038] An electrical component support mechanism according to an embodiment of this utility model includes:

[0039] The two guide grooves 1 are the sliding base structure of the entire support mechanism, and are installed in parallel inside the detection device;

[0040] The two support frames 2 are the core structure supporting the electrical components. They are set as a grid structure, and the grid structure includes a short shaft 21 and a long shaft 22. Movable parts 3 are rotatably installed at both ends of the long shaft 22. The movable parts 3 at both ends of the long shaft 22 are slidably installed in the two guide grooves 1.

[0041] Connector 4 is rotatably mounted to two short shafts 21, and connector 4 is provided with a fixing plate 5 for mounting electrical components;

[0042] A positioning mechanism 6 is provided on each of the two guide grooves 1. The positioning mechanism 6 is used to lock the connection position between the moving part 3 and the guide groove 1.

[0043] The limiting mechanism 7 is installed in conjunction with the detection device and the connecting piece 4 respectively. The limiting mechanism 7 is used to limit the movement trajectory of the fixed plate 5.

[0044] By adopting the above technical solution, the guide groove 1 provides a sliding base for the moving part 3. The moving parts 3 at both ends of the long shaft 22 of the grid-shaped support frame 2 slide along the guide groove 1, which can drive the entire support mechanism and electrical components to move out or into the testing device, meeting the operational needs during assembly and maintenance. The connecting part 4 is rotatably connected to the short shaft 21, and together with the fixing plate 5, it provides a stable mounting position for the electrical components, ensuring reliable component installation. The positioning mechanism 6 can lock the position of the moving part 3 and the guide groove 1 to prevent the electrical components from accidentally sliding during operation or maintenance / assembly. The limiting mechanism 7 restricts the movement trajectory of the fixing plate 5 to avoid excessive displacement during removal, which could lead to structural damage. The overall structure takes into account both support stability and operational flexibility, making it convenient and efficient to move electrical components inside and outside the testing device, greatly improving the work efficiency of assembly and maintenance.

[0045] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the positioning mechanism 6 includes:

[0046] Two mounting parts 61 are symmetrically mounted on the guide groove 1. A positioning pin 62 is slidably provided inside the mounting part 61. The positioning pin 62 is connected to the teeth provided on the moving part 3. An extension part 63 is provided on the positioning pin 62 and passes through the inner hole of the mounting part 61.

[0047] The first spring 64 is mounted on the positioning pin 62, and the other end of the first spring 64 is connected to the inner groove of the mounting part 61.

[0048] The transmission mechanism 65 is connected to two extensions 63 on the same guide groove 1, and is used to connect and disconnect the positioning pin 62 from the moving part 3.

[0049] Two positioning mechanisms 6 on the two guide slots 1, one for locking the position of the moving part 3 when the fixed plate 5 is unfolded, and the other for locking the position of the moving part 3 when the fixed plate 5 is folded up;

[0050] In this embodiment, the positioning pin 62 inside the mounting component 61 engages with the teeth of the moving component 3 under the elastic force of the first spring 64, which can securely lock the position of the moving component 3. The positioning mechanisms 6 on the two guide grooves 1 correspond to the unfolded and retracted states of the fixed plate 5, ensuring that the electrical components can be stably positioned when working or being moved. The transmission mechanism 65 connects the two extensions 63 of the same guide groove 1, which can simultaneously drive the positioning pin 62 to disengage from the teeth to unlock. The operation is convenient and labor-saving. The overall structure can reliably lock the moving component 3 to prevent accidental sliding, and can also be quickly unlocked through the transmission mechanism 65. With the sliding of the support frame 2, the electrical components can be flexibly unfolded and retracted, improving the efficiency of the assembly and maintenance of electrical components in the testing device and ensuring the safety and stability of the operation process.

[0051] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the transmission mechanism 65 includes:

[0052] A connecting beam 65a is fixedly connected to two extension members 63. A transmission beam 65b is provided on the connecting beam 65a. The transmission beam 65b and the connecting beam 65a form a T-shaped structure.

[0053] A drive block 65c is installed at the end of the transmission beam 65b, and an anti-slip structure is provided on the drive block 65c.

[0054] A guide 66 is provided on the transmission beam 65b, which is used to limit the movement trajectory of the transmission beam 65b.

[0055] In this embodiment, the connecting beam 65a is fixedly connected to the two extensions 63. Together with the T-shaped transmission beam 65b, it can synchronously drive the two positioning pins 62 to disengage from the teeth of the moving part 3, ensuring the consistency of the unlocking action. The anti-slip structure at the end of the drive block 65c increases the grip friction, making it easier to drive the transmission beam 65b with less effort, thus improving the ease of unlocking. The guide 66 restricts the movement trajectory of the transmission beam 65b, ensuring the stability of the operation and the structural strength of the device.

[0056] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, a second spring 8 is provided at both ends of the moving part 3 in the moving direction. The second spring 8 is used to drive the moving part 3 to move after it is disengaged from the positioning pin 62.

[0057] In this embodiment, after the positioning pin 62 disengages from the moving part 3, the second springs 8 at both ends of the moving part 3 can drive the moving part 3 to automatically move along the guide groove 1 through elastic force, so that the moving part 3 can quickly disengage from the positioning pin 62, thereby improving the ease of operation of the electrical component support mechanism.

[0058] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the limiting mechanism 7 includes:

[0059] A movable shaft 71 is mounted on a connector 4, and a limit post 72 is provided on the movable shaft 71.

[0060] Hollow shaft 73 is installed inside the detection device, movable shaft 71 is slidably installed inside the shaft cavity of hollow shaft 73, and limiting post 72 is slidably connected to the limiting slot hole of hollow shaft 73;

[0061] In this embodiment, the movable shaft 71 is slidably installed in the cavity of the hollow shaft 73. The sliding connection between the limiting post 72 and the limiting slot of the hollow shaft 73 can strictly limit the movement direction and stroke of the connecting piece 4, prevent the fixed plate 5 from shifting during unfolding or storage, and avoid internal structural collisions or jamming. This structure provides stable guidance for the connecting piece 4, ensuring that the support frame 2 drives the electrical components to move smoothly along the preset trajectory.

[0062] As a preferred embodiment of the above technical solution, such as Figures 1 to 4 As shown, the fixing plate 5 is provided with multiple assembly key holes;

[0063] In this embodiment, the multiple assembly keyholes on the fixing plate 5 provide diverse installation position options for electrical components of different specifications and types, which can be flexibly adapted according to the size and installation requirements of the electrical components, thereby improving the compatibility of the fixing plate 5 with various electrical components.

[0064] The electrical component support mechanism of this utility model can be used in various types of transformer oil gas monitoring devices;

[0065] Compared with existing electrical component support mechanisms, the electrical component support mechanism of this utility model realizes flexible removal and stable support of electrical components inside and outside the detection device, making the unfolding and storage operations more convenient, improving the installation compatibility of electrical components, and greatly improving the assembly and maintenance efficiency of electrical components. It is especially suitable for detection devices such as transformer oil gas monitoring devices and similar distribution boxes, and adapts to the installation needs of electrical components of different specifications.

[0066] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
