Description

Technical Field

[0001] This utility model relates to the field of high-voltage switchgear technology, specifically to an improved switchgear door panel device. Background Technology

[0002] High-voltage switchgear refers to electrical products used in power systems for switching, control, or protection in power generation, transmission, distribution, energy conversion, and consumption. Classified by voltage level of 3.6kV, high-voltage switchgear mainly includes several categories such as high-voltage circuit breakers, high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgear itself. Existing box-type fixed metal-enclosed switchgear typically has its operating buttons located on the door panel. For ease of operation, the door panel usually needs hinges to open for operation. However, this design presents safety hazards, as operators can easily access the high-voltage equipment inside the switchgear once the door is opened.

[0003] A closing device for a high-voltage switchgear door panel disclosed in Chinese Utility Model Patent Application Publication No. CN211829637U, while improving safety by inserting a pin into the plug to block it and prevent it from being squeezed between the rollers, creating a gap between the door panel and the side panel to avoid accidental closing and finger injury, does not address the issue that if a component malfunctions after the device is installed on the switchgear door panel, the entire device needs to be disassembled and replaced with a new one. Since other parts of the device are undamaged, discarding it results in significant losses. Furthermore, in existing box-type fixed metal-enclosed switchgear or switchgear, the operating buttons are usually located inside the switchgear door panel. When the door is opened, operators can easily access the high-voltage equipment inside the switchgear, posing a safety hazard. Therefore, we propose a novel device to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an improved switchgear door panel device, which solves the problem that the control buttons are located inside the switchgear door panel, requiring operators to open the door panel to operate the control buttons, and that operators may accidentally touch the high-voltage equipment inside the switchgear after the door panel is opened.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an improved switch cabinet door panel device, comprising a bracket, a support plate fixedly connected to one side of the bracket, a support seat fixedly connected to one side of the support plate, a support bolt threaded through the internal thread of the support seat, a door frame snapped into the inside of the support plate, a spring telescopic rod fixedly connected to the inside of the door frame, a limit block fixedly connected to the upper surface of the spring telescopic rod, a limit rod fixedly connected to the lower surface of the limit block, a connecting seat fixedly connected to one side of the door frame, a connecting rod rotatably connected to the inside of the connecting seat, a connecting shaft seat rotatably connected to the surface of the connecting rod, a fixed door panel rotatably connected to the surface of the connecting rod, a threaded post fixedly connected to the lower surface of the connecting rod, a nut threaded through the surface of the threaded post, a positioning seat rotatably connected to the inside of the fixed door panel, a positioning rod inserted into the inside of the positioning seat, and a positioning plate fixedly connected to one side of the positioning seat.

[0008] Optionally, the bracket has two holes inside, and the size of both holes is adapted to the size of the operation buttons on the switch cabinet door panel.

[0009] Optionally, the support plate has a fixing groove inside, and the upper surface of the limiting block has a protrusion, the size of the fixing groove being adapted to the size of the protrusion.

[0010] Optionally, a fixing groove is provided on the upper surface of the door frame, and the door frame is slidably connected to the limiting block through the fixing groove.

[0011] Optionally, a limiting hole is provided inside the door frame, and the door frame is slidably connected to the limiting rod through the limiting hole.

[0012] Optionally, a positioning groove is provided inside the door frame, and the door frame is adapted to the positioning plate through the positioning groove.

[0013] Optionally, a cross-shaped groove is provided on one side of the positioning plate, and the size of the cross-shaped groove is adapted to the size of the positioning rod.

[0014] Optionally, the fixed door panel has internal threads through which fixing bolts pass, and the fixed door panel has fixing seats through which fixing bolts pass. There are four fixing bolts and four fixing seats. A glass door is fixedly connected to one side of the fixing seat.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model has a reasonable structure. By placing the bracket on one side of the switch cabinet door panel and covering the switch button on the door panel through the hole, the support bolts are tightened to pass through the support base and the switch cabinet door panel, fixing the bracket, support plate, and support base to the switch cabinet door panel. By pulling down the limit rod near the upper part of the door frame and pulling up the limit rod near the lower part of the door frame, the spring telescopic rod retracts, and the limit block slides into the interior of the door frame, then the door frame is snapped into the interior of the support plate. By releasing all the limit rods, the spring telescopic rod releases pressure, allowing the protrusion of the limit block to insert into the fixing groove, thus connecting and fixing the door frame to the support plate. By connecting the connecting shaft seat to the connecting base, and passing the connecting rod through the connecting shaft seat and the connecting base, and then rotating the nut, the nut moves upward. This design limits the connecting rod, thereby connecting the fixed door panel to the door frame. By contacting the glass door with the fixed door panel and tightening the fixing bolts, the fixing bolts pass through the fixing seat and the fixed door panel, thus fixing the glass door to the fixed door panel. If any of the door frame, fixed door panel, glass door, or bracket is damaged, it can be directly disassembled and replaced with a new part. This reduces the need to disassemble the entire device and replace it with a new one when a part fails after the device is installed on the switch cabinet door panel. This avoids situations where other parts of the device are not damaged and are discarded, resulting in significant losses. The design achieves the effect that if a part of the device is damaged, it can be disassembled and a new part can be installed to allow the device to continue to be used.

[0017] 2. In this utility model, by inserting the positioning rod through the positioning seat and into the positioning plate, and then rotating the positioning rod to rotate the positioning plate into the positioning groove of the door frame, the fixed door panel can be prevented from opening, and vice versa. This reduces the safety hazards associated with existing box-type fixed metal enclosed switchgear or switch cabinets, where the operating buttons are usually located inside the switch cabinet door panel. When the door panel is opened, operators can easily access the high-voltage equipment inside the switch cabinet. By installing the switch button on the switch cabinet door panel and then blocking the switch button position with the fixed door panel, the risk of accidental switch button operation is reduced. At the same time, when the switch button needs to be operated, it can be operated by opening the fixed door panel, thereby reducing the risk of operators accidentally touching high-voltage equipment due to the need to directly open the switch cabinet door panel to operate the switch button.

[0024] Example: Reference Figures 1-4 An improved switch cabinet door panel device is shown, comprising a bracket 1, a support plate 2 fixedly connected to one side of the bracket 1, a support seat 3 fixedly connected to one side of the support plate 2, a support bolt 4 threaded through the internal thread of the support seat 3, a door frame 5 snapped into the internal thread of the support plate 2, a spring telescopic rod 6 fixedly connected to the internal thread of the door frame 5, a limit block 7 fixedly connected to the upper surface of the spring telescopic rod 6, a limit rod 8 fixedly connected to the lower surface of the limit block 7, a connecting seat 9 fixedly connected to one side of the door frame 5, a connecting rod 10 rotatably connected to the internal thread of the connecting seat 9, a connecting shaft seat 101 rotatably connected to the surface of the connecting rod 10, a fixed door panel 11 rotatably connected to the surface of the connecting rod 10, a threaded post 12 fixedly connected to the lower surface of the connecting rod 10, a nut 13 threaded through the surface of the threaded post 12, a positioning seat 14 rotatably connected to the internal thread of the fixed door panel 11, a positioning rod 15 inserted into the internal thread of the positioning seat 14, and a positioning plate 16 fixedly connected to one side of the positioning seat 14.

[0025] As a preferred embodiment of this example, Figures 1-4As shown, a support plate 2 is fixedly connected to one side of the bracket 1. The bracket 1 has two holes inside, both of which are sized to match the operating buttons on the switch cabinet door panel. A support base 3 is fixedly connected to one side of the support plate 2. A support bolt 4 passes through the internal thread of the support base 3. A door frame 5 is snapped into the inside of the support plate 2. A spring telescopic rod 6 is fixedly connected inside the door frame 5. A limit block 7 is fixedly connected to the upper surface of the spring telescopic rod 6. A fixing groove is provided inside the support plate 2. A protrusion is provided on the upper surface of the limit block 7, and the size of the fixing groove matches the size of the protrusion. A fixing groove is provided on the upper surface of the door frame 5. The door frame 5 is slidably connected to the limit block 7 through the fixing groove. A limit rod 8 is fixedly connected to the lower surface of the limit block 7. The door frame 5 has a limiting hole inside, and the door frame 5 is slidably connected to the limiting rod 8 through the limiting hole. A connecting seat 9 is fixedly connected to one side of the door frame 5. A connecting rod 10 is rotatably connected inside the connecting seat 9. A connecting shaft seat 101 is rotatably connected to the surface of the connecting rod 10. A fixed door panel 11 is rotatably connected to the surface of the connecting rod 10. A threaded post 12 is fixedly connected to the lower surface of the connecting rod 10. A nut 13 is threaded through the surface of the threaded post 12. A fixing bolt 17 is threaded through the inside of the fixed door panel 11. A fixing seat 18 is threaded through the fixing bolt 17 on the fixed door panel 11. There are four fixing bolts 17 and four fixing seats 18. A glass door 19 is fixedly connected to one side of the fixing seat 18. During use, the bracket 1 is placed on the switch cabinet door panel. On one side, the switch button on the switch cabinet door panel is covered through a hole. By tightening the support bolt 4, the support bolt 4 passes through the support base 3 and the switch cabinet door panel, fixing the bracket 1, support plate 2, and support base 3 to the switch cabinet door panel. By pulling down the limit rod 8 near the upper part of the door frame 5 and pulling up the limit rod 8 near the lower part of the door frame 5, the spring telescopic rod 6 retracts, and at the same time, the limit block 7 slides into the interior of the door frame 5, then the door frame 5 is snapped into the interior of the support plate 2. By releasing all the limit rods 8, the spring telescopic rod 6 releases pressure, allowing the protrusion of the limit block 7 to insert into the fixing groove, thus connecting and fixing the door frame 5 to the support plate 2. By connecting the connecting shaft seat 101 to the connecting seat 9, the connecting rod 10 passes through the connecting shaft seat 101. The connecting rod 10 is limited by rotating the connecting seat 9 and rotating the nut 13 to move the nut 13 upwards, thereby connecting the fixed door panel 11 to the door frame 5. The glass door 19 is then brought into contact with the fixed door panel 11, and the fixing bolt 17 is tightened, allowing it to pass through the fixing seat 18 and the fixed door panel 11, thus fixing the glass door 19 to the fixed door panel 11. If any one of the door frame 5, fixed door panel 11, glass door 19, or bracket 1 is damaged, it can be directly disassembled and replaced with a new one. This reduces the need to disassemble the entire device and replace it if a single part fails after the device is installed on the switch cabinet door panel, ensuring that only one part is damaged while the others remain undamaged.Directly discarding it would cause significant losses. This solution achieves the goal of allowing the device to continue functioning after a damaged part is disassembled and replaced with a new one.

[0026] like Figure 4 As shown, in this embodiment, a positioning seat 14 is rotatably connected inside the fixed door panel 11, and a positioning rod 15 is inserted into the positioning seat 14. A positioning plate 16 is fixedly connected to one side of the positioning seat 14. A positioning groove is provided inside the door frame 5, and the door frame 5 is adapted to the positioning plate 16 through the positioning groove. A cross groove is provided on one side of the positioning plate 16, and the size of the cross groove is adapted to the size of the positioning rod 15. In use, by passing the positioning rod 15 through the positioning seat 14 to insert the positioning rod 15 into the positioning plate 16, and then by rotating the positioning rod 15, the positioning plate 16 is rotated into the positioning groove of the door frame 5, thus preventing the fixed door panel 11 from opening. Conversely, the door panel 11 cannot be opened. This allows the fixed door panel 11 to be opened, reducing the risk of accidental contact with high-voltage equipment. In existing box-type fixed metal-enclosed switchgear or switch cabinets, the operating buttons are usually located on the switch cabinet door panel. When the door panel is opened, operators can easily access the high-voltage equipment inside the switch cabinet, posing a safety hazard. By installing the switch button inside the switch cabinet door panel and then covering the switch button location with the fixed door panel 11, the risk of accidental contact with the switch button is reduced. At the same time, when it is necessary to operate the switch button, it can be operated by opening the fixed door panel 11, thereby reducing the risk of operators accidentally touching high-voltage equipment due to the need to directly open the switch cabinet door panel to operate the switch button.

[0027] The working principle of this practical application is as follows:

[0028] During use, the bracket 1 is placed on one side of the switch cabinet door panel, covering the switch button on the switch cabinet door panel through the hole. By tightening the support bolt 4, the support bolt 4 passes through the support base 3 and the switch cabinet door panel, fixing the bracket 1, support plate 2, and support base 3 to the switch cabinet door panel. By pulling down the limit rod 8 near the upper part of the door frame 5 and pulling up the limit rod 8 near the lower part of the door frame 5, the spring telescopic rod 6 retracts, and the limit block 7 slides into the interior of the door frame 5, then the door frame 5 is snapped into the interior of the support plate 2. By releasing all the limit rods 8, the spring telescopic rod 6 releases pressure, allowing the protrusion of the limit block 7 to insert into the fixing groove, thus connecting and fixing the door frame 5 to the support plate 2. By connecting the connecting shaft seat 101 to the connecting seat 9, the connecting rod 10 passes through the connecting shaft seat 101. Connecting the connecting seat 9, and then rotating the nut 13 to move the nut 13 upward, thereby limiting the connecting rod 10, thus connecting the fixed door panel 11 to the door frame 5. By contacting the glass door 19 with the fixed door panel 11, and by tightening the fixing bolt 17, the fixing bolt 17 passes through the fixing seat 18 and the fixed door panel 11, thereby fixing the glass door 19 to the fixed door panel 11. If any of the door frame 5, the fixed door panel 11, the glass door 19, and the bracket 1 is damaged, it can be directly disassembled and replaced with a new part. By passing the positioning rod 15 through the positioning seat 14 to insert the positioning rod 15 into the positioning plate 16, and then by rotating the positioning rod 15, the positioning plate 16 rotates into the positioning groove of the door frame 5, thus preventing the fixed door panel 11 from opening, and vice versa, allowing the fixed door panel 11 to open.
