Description

Technical Field

[0001] This application relates to the field of low-voltage capacitor banks, and more specifically, to a safety lock device for low-voltage capacitor banks. Background Technology

[0002] Low-voltage capacitor banks have a wide range of applications and can be used as reactive power compensation devices to compensate for reactive power in power supply systems with a rated voltage of 380V in various industries. In specific applications, reactive power compensation can be performed manually or automatically according to the needs of the power grid, stabilizing the voltage quality of the power grid, reducing losses in the transmission and distribution system and transformers, thereby achieving the goals of energy saving and improving the power supply quality of the power grid.

[0003] When staff inspect the inside of the cabinet, they need to open the cabinet door. When not inspecting, the cabinet door is usually closed. However, in the current technology, the cabinet door is only equipped with a closing device and there is no protective structure. This makes it easy for unauthorized personnel to open the cabinet door, which can easily cause danger.

[0004] A safety lock device for a low-voltage capacitor bank is now provided. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section above, some embodiments of this application provide a safety lock device for a low-voltage capacitor bank, comprising: a cabinet; two cabinet doors, symmetrically hinged to the cabinet; a mounting groove on the right-hand cabinet door; a rotating shaft, rotatably mounted on the mounting groove; a fixing rod, fixedly connected to the rotating shaft and disposed on the mounting groove; and a handle, fixedly connected to the rotating shaft and disposed on the outside. A connecting groove is provided on the left-hand cabinet door, and the connecting groove corresponds to the fixing rod; a fixing groove is provided on the fixing rod; a fixing rubber is fixed to the inner wall of the connecting groove, and the fixing rubber corresponds to the fixing groove; a snap-fit ​​groove is provided on the fixing rod; a fixing component is provided on the connecting groove, and the fixing component corresponds to the snap-fit ​​groove; wherein, the fixing component is used to further fix the fixing rod.

[0007] When the door needs to be closed, the handle can be turned, causing the pivot to rotate and the fixing rod to rotate into the connecting groove. When the fixing rod rotates to contact the limiting strip, the limiting strip abuts against the fixing rod, preventing it from rotating further. At this point, the fixing rubber is compressed and deformed, allowing it to engage with the fixing groove, thus initially limiting and fixing it, and initially closing both cabinet doors. Then, under the action of the fixing spring, the sliding rod engages with the engaging groove, further securing the fixing rod and ensuring the cabinet door closes stably. The baffle plate blocks the lever, improving the safety factor. The limiting rubber also compresses the baffle plate, improving the stability of the baffle plate installation. When it needs to be opened, the baffle plate is opened, and then the sliding rod can be moved using the lever.

[0008] In some embodiments, the fixing assembly includes a sleeve and a slide rod. The sleeve is fixedly connected to the inside of the connecting groove, and the slide rod is slidably mounted on the sleeve and corresponds to the fixing groove. A fixing spring is fixedly connected between the slide rod and the inner wall of the sleeve. A lever is fixedly connected to the slide rod, and an opening corresponding to the lever is opened in the connecting groove.

[0009] In some embodiments, a baffle plate is hinged to the inner wall of the opening, and the baffle plate corresponds to the lever, and a pull rod is fixed to the baffle plate.

[0010] In some embodiments, an overlap plate is fixed to the inner wall of the opening, and the overlap plate corresponds to the baffle plate, and a limiting rubber for squeezing the baffle plate is fixed to the overlap plate.

[0011] In some implementations, the slide bar is cylindrical.

[0012] In some implementations, a handle is fixed to the cabinet door on the left end.

[0013] In some implementations, the retaining spring is disposed inside the sleeve.

[0014] In some embodiments, a limiting strip is fixed to the inner wall of the connecting groove, and the limiting strip is used to limit the fixing rod.

[0015] In some implementations, the limiting strip is square.

[0016] In some implementations, the handle is U-shaped.

[0017] The beneficial effects of this application are as follows: By setting a fixed rod, a sliding rod, a sleeve, and a rotating shaft, when it is necessary to close the door, the handle can be turned, thereby causing the rotating shaft to rotate, which in turn causes the fixed rod to rotate into the connecting groove. When the fixed rod rotates to contact the limiting strip, it abuts against the fixed rod under the action of the limiting strip, preventing the fixed rod from rotating. At this time, the fixing rubber is compressed and deformed, allowing the fixing rubber to engage with the fixing groove, thus initially limiting and fixing it, thereby initially closing the two cabinet doors. Then, under the action of the fixing spring, the sliding rod engages with the engaging groove, thereby further fixing the fixed rod, thus making the cabinet door close stably. Furthermore, under the action of the baffle, the lever is blocked, thereby improving the safety factor. Under the action of the limiting rubber, the baffle is compressed, thereby improving the stability of the baffle installation. When it is necessary to open, the baffle is opened, and then the sliding rod can be moved by the lever. Attached Figure Description

Two cabinet doors 2 are provided and symmetrically hinged to the cabinet body 1. The mounting groove 3 is located on the right-hand cabinet door 2. The rotating shaft 4 is rotatably mounted on the mounting groove 3. The fixing rod 7 is fixed to the rotating shaft 4 and is positioned on the mounting groove 3. The handle 17 is fixed to the rotating shaft 4 and is located on the outside. The connecting groove 8 is located on the left-hand cabinet door 2 and corresponds to the fixing rod 7. The fixing groove 5 is located on the fixing rod 7. The fixing rubber 6 is fixed to the inner wall of the connecting groove 8 and corresponds to the fixing groove 5. The snap-fit ​​groove 9 is located on the fixing rod 7. The fixing component is located on the connecting groove 8 and corresponds to the snap-fit ​​groove 9. The fixing component is used to further fix the fixing rod 7.

[0028] The low-voltage capacitor bank fixing assembly includes a sleeve 11 and a slide rod 21. The sleeve 11 is fixedly connected to the inside of the connecting groove 8, and the slide rod 21 is slidably installed on the sleeve 11. The slide rod 21 corresponds to the fixing groove 5. A fixing spring 10 is fixedly connected between the slide rod 21 and the inner wall of the sleeve 11. A lever 14 is fixedly connected to the slide rod 21, and an opening 12 corresponding to the lever 14 is opened on the connecting groove 8.

[0029] A baffle plate 15 is hinged to the inner wall of the opening 12 of the low-voltage capacitor cabinet, and the baffle plate 15 corresponds to the lever 14, and a pull rod 16 is fixed to the baffle plate 15.

[0030] An overlapping plate 19 is fixedly connected to the inner wall of the opening 12 of the low-voltage capacitor bank, and the overlapping plate 19 corresponds to the baffle plate 15. A limiting rubber 18 for squeezing the baffle plate 15 is fixedly connected to the overlapping plate 19. The sliding rod 21 of the low-voltage capacitor bank is cylindrical. A handle 13 is fixedly connected to the cabinet door 2 at the left end of the low-voltage capacitor bank.

[0031] The low-voltage capacitor bank fixing spring 10 is installed inside the sleeve 11.

[0032] Working process: When it is necessary to close the door, the handle 17 can be turned, which causes the rotating shaft 4 to rotate, thereby causing the fixed rod 7 to rotate into the connecting groove 8. When the fixed rod 7 rotates to contact the limiting strip 20, it abuts against the fixed rod 7 under the action of the limiting strip 20, so that the fixed rod 7 stops rotating. At this time, the fixing rubber 6 is squeezed and deformed, which allows the fixing rubber 6 to be locked onto the fixing groove 5, thereby initially limiting and fixing it, thus initially closing the two cabinet doors 2. Then, under the action of the fixing spring 10, the sliding rod 21 is locked onto the locking groove 9, thereby further fixing the fixed rod 7, thus making the cabinet door 2 close stably. Under the action of the baffle plate 15, the lever 14 is blocked, thereby improving the safety factor. Under the action of the limiting rubber 18, the baffle plate 15 is squeezed, thereby improving the stability of the baffle plate 15 installation. When it is necessary to open, the baffle plate 15 is opened, and then the sliding rod 21 can be moved by the lever 14.
