Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to an anti-collision door device and a switch cabinet. Background Technology

[0002] Switchgear (especially rotary switchgear) is usually equipped with a door that can be opened and closed. When the door is open, a circuit breaker outside the cabinet can be sent into the cabinet through the door or a circuit breaker inside the cabinet can be taken out. However, sometimes when the circuit breaker is sent into the cabinet, the door may not be fully opened. In this case, the circuit breaker may collide with the door, which may damage the door. Utility Model Content

[0003] This utility model addresses the shortcomings of existing methods by proposing an anti-collision valve device and switch cabinet to solve the technical problem in the prior art where the valve is not fully opened but external components pass through unobstructed, causing an impact on the valve body.

[0004] In the first aspect, this utility model provides an anti-collision door device, including a support, a blocking component, a reset component, a door body, and a door frame;

[0005] The door body is movably mounted on the door frame and has an open position and a closed position;

[0006] The support is disposed on the outside of the door body, the blocking component is movably disposed on the support, defining one end of the blocking component as a blocking end, the blocking end is configured to extend into the frame area of ​​the door frame and constitute the passage lock of the frame area, and the reset member is disposed on the support and acts on the blocking component.

[0007] During the movement of the door from the closed position to the open position, when the door contacts and acts on the blocking component, the door drives the blocking end to move towards the support, and when the door reaches the open position, the blocking end releases the passage lock on the area inside the frame.

[0008] Conversely, the door body in the open position moves to the closed position to release the door body from the blocking component, and the reset member drives the blocking end to reset to the passage-locked state.

[0009] Optionally, the blocking assembly includes a stop bar;

[0010] The stop bar and the reset member are disposed in the support, one end of the stop bar is the blocking end, and the reset member acts on the stop bar.

[0012] Optionally, the blocking assembly further includes a pressure bar;

[0013] One end of the pressure rod is rotatably connected between the two ends of the lever arm, and the other end of the pressure rod is the working end;

[0014] As the door moves from the closed position to the open position, it acts on the actuating end to drive the blocking end to move and unlock the area within the frame.

[0015] Optionally, the support is provided with a first guide groove on one side of the stop bar, which is arranged along the movement direction of the stop bar;

[0016] The blocking assembly further includes a stop pin passing through the first guide groove, and the lever arm and the stop rod are respectively rotatably connected to the stop pin.

[0017] Optionally, a second guide groove is provided on one side of the pressure rod, arranged along the movement direction of the pressure rod;

[0018] The blocking assembly further includes a pressure pin passing through the second guide groove, and the lever arm and the pressure rod are respectively rotatably connected to the pressure pin.

[0019] Optionally, the number of lever arms is two;

[0020] The two lever arms are positioned opposite each other on both sides of the pressure bar.

[0021] Optionally, the door body moves in a straight line relative to the door frame.

[0022] Optionally, the central axes of the stop bar and the pressure bar are arranged parallel to each other, and the plane containing the central axes of the two is defined as a first plane, which is arranged parallel to the front of the door.

[0023] Optionally, the door body includes a door panel and a pressure plate disposed at one end of the door panel, the pressure plate being able to act on the blocking assembly to drive the blocking end to unlock the area within the frame.

[0024] Secondly, this utility model embodiment provides a switch cabinet, including a cabinet body, a circuit breaker, and an anti-collision door device as described above;

[0025] The cabinet is provided with a receiving cavity for accommodating the circuit breaker, and at least one side of the receiving cavity is provided with an opening for installing the door frame. The door is configured to open or close the opening.

[0026] The blocking component is located on the outside of the door.

[0027] Optionally, it also includes a mounting rail for guiding the circuit breaker in and out of the receiving cavity;

[0028] The mounting rail is located in the frame area and is arranged along the depth direction of the receiving cavity. The blocking end is configured to block the installation rail along its length direction to prevent the circuit breaker from docking onto the mounting rail and then entering the receiving cavity through the door frame.

[0029] The beneficial technical effects brought about by the technical solution provided by this utility model embodiment include:

[0030] First, the door and the blocking component are linked; the blocking component only opens the door frame after the door reaches the open position. Conversely, when the door is not fully open, the blocking component effectively prevents external components (e.g., a circuit breaker) from passing through, avoiding impact and damage to the door. Second, the direct linkage between the door and the blocking component in this invention results in a simple and reliable structure that effectively prevents impact damage to the door.

[0043] The anti-collision valve device provided by this utility model aims to solve the above-mentioned technical problems in the prior art.

[0044] The technical solution of this utility model and how the technical solution of this utility model solves the above-mentioned technical problems will be described in detail below with specific embodiments.

[0045] This utility model provides an anti-collision gate device, the structural schematic diagram of which is shown below. Figure 1 As shown, it includes:

[0046] The system comprises a support 10, a blocking component 20, a reset component 30, a door body 40, and a door frame 50. The door body 40 is movably disposed on the door frame 50 and has an open position and a closed position. The support 10 is disposed on the outside of the door body 40, and the blocking component 20 is movably disposed on the support 10, defining one end of the blocking component 20 as a blocking end 201. The blocking end 201 is configured to extend into the inner area of ​​the door frame 50 and constitute a passage lock for the inner area. The reset component 30 is disposed on the support 10 and acts on the blocking component 20. During the movement of the door body 40 from the closed position to the open position, it acts on the blocking component 20, driving the blocking end 201 to move closer to the support 10. When the door body 40 reaches the open position, the blocking end 201 releases the passage lock for the inner area. Conversely, when the door body 40 in the open position moves to the closed position, the door body 40 releases its interaction with the blocking component 20, and the reset component 30 drives the blocking end 201 to reset to the passage lock state.

[0047] For example, the support 10 is located outside the projection range of the frame area (more preferably the inner frame area) of the door frame 50, and preferably, when the door body 40 is in the open position, both its entirety and the blocking end 201 are located outside the frame area of ​​the door frame 50, thereby minimizing the interference of these two components (e.g., a circuit breaker) when passing through the door frame 50.

[0048] In this embodiment, the door 40 moves linearly relative to the door frame 50, and the door 40 moves in the vertical direction. The door 40 moves downward to open and upward to close. Thus, the door 40 is in the closed position when it moves to its highest position and in the open position when it moves to its lowest position.

[0049] It can also be understood that the passage area required for an external component (e.g., a circuit breaker) to pass through the door frame 50 may be smaller than the area inside the frame. Therefore, the passage area for an external component (e.g., a circuit breaker) is less than or equal to the area inside the frame. Thus, the passage-locked state of the aforementioned barrier end 201 refers to the barrier end 201 entering the passage area. Therefore, the release of the passage-lock by the barrier end 201 from the area inside the frame corresponds to its withdrawal from the passage area. However, based on the explanation that the passage area is less than or equal to the area inside the frame, if the barrier end 201 withdraws to outside the area inside the frame, it also satisfies the requirement of withdrawing from the passage area. This can be understood as the release of the passage-lock.

[0050] In summary, the door 40 controls the passage of the blocking component 20 in the open position through an interlocking relationship with the blocking component 20 at a specific location. Thus, after the door 40 is fully opened, the blocking component 20 is released from the passage lock to allow external components (in switchgear applications, this external component can be understood as the circuit breaker 70) to pass through the door frame 50. Conversely, any external component that wishes to pass before the passage lock is released is blocked by the blocking component 20.

[0051] Other aspects mentioned in this embodiment, such as the vertical movement of the door 40, and the sliding connection between the door 40 and the door frame 50 via a slider and slide rail mechanism, will not be elaborated here.

[0052] Furthermore, at least one linear guide rail 90 is provided on the door body 40. The linear guide rail 90 is movably arranged relative to the door frame 50. The linear guide rail 90 guides the movement of the door body 40 between the open and closed positions, ensuring the stability of the door body 40 during movement. In addition, the lifting and lowering of the door body 40 can also be achieved by electric opening and closing through the cooperation of a motor and a transmission chain, which will not be elaborated here.

[0053] Optionally, the door body 40 includes a door panel 41 and a pressure plate 42 disposed at one end of the door panel 41. The pressure plate 42 can act on the blocking assembly 20 to drive the blocking end 201 to unlock the area inside the frame.

[0054] Specifically, the pressure plate 42 is positioned on the top of the door panel 41 and extends towards the support 10. The vertical projection of the pressure plate 42 covers the top of the pressure rod 23 (acting end 2301). Thus, the pressure plate 42 acts on the acting end 2301, causing the power arm 22 to rotate clockwise. At the same time, the clockwise rotation of the power arm 22 also causes the stop bar 21 to move downward, that is, the blocking component 20 moves downward to achieve passage and unlocking of the area within the frame.

[0055] Optionally, see Figure 2 and Figure 4 The blocking assembly 20 includes a stop bar 21; the stop bar 21 and the reset member 30 are disposed in the support 10, one end of the stop bar 21 is the blocking end 201, and the reset member 30 acts on the stop bar 21.

[0056] In this embodiment, a stop bar 21 is used as a barrier to block external components. As described above, the top end of the stop bar 21 is the blocking end 201. For example, the reset member 30 is a spring, and the stop bar 21 includes a main rod 211 and a limiting ring 212 located in the middle of the main rod 211. The diameter of the limiting ring 212 is larger than the diameter of the main rod 211. The support 10 has a first shaft hole 1001 and a second shaft hole 1002 that communicate with each other from bottom to top. The first shaft hole 1001 and the second shaft hole 1002 penetrate the support 10, and the diameter of the first shaft hole 1001 is larger than the diameter of the second shaft hole 1002. The stop bar 21 passes through the first shaft hole 1001 and the second shaft hole 1002 from bottom to top. The main rod 211 passes through the first shaft hole 1001 and the second shaft hole 1002, and the limiting ring 212 is located in the first shaft hole 1001 but cannot enter the second shaft hole 1002. The spring is sleeved on the main rod 211 and located below the limiting ring 212. The bottom of the first shaft hole 1001 can be sealed by a sealing plate, which has a through hole for the lower end of the main rod 211 to pass through.

[0057] The key aspect of this embodiment is the linkage process between the door 40 and the blocking assembly 20 when the door 40 opens. The door 40 moves downwards, causing the pressure plate 42 to abut against the top of the pressure rod 23 (actual end 2301), which in turn moves downwards. Simultaneously, the stop rod 21 also moves downwards, causing the main rod 211, along with the limiting ring 212, to move downwards. The bottom end of the main rod 211 can pass through the sealing plate through-hole. The spring is compressed by the limiting ring 212 until the pressure plate 42 reaches its lowest point (the door 40 reaches the open position and is entirely outside the frame area). At this point, the main rod 211 completely exits the frame area, thus releasing the aforementioned passage lock. Conversely, when the door is in the open position, it moves upwards to reset. During this process, the spring returns to push the main rod 211 upwards to reset, and finally, when the pressure plate 42 returns to its highest point, the door 40 is in the closed position.

[0058] Optionally, the blocking assembly 20 also includes a lever arm 22, one end of which is rotatably mounted on the support 10, and the other end is connected to the stop bar 21.

[0059] For example, lever arm 22 is a connecting plate, and one end of lever arm 22 rotates on the middle section of main rod 211. At this time, pressure plate 42 can be selected to act on lever arm 22 to drive stop rod 21 to move downward.

[0060] Optionally, the blocking assembly 20 also includes a pressure rod 23; one end of the pressure rod 23 is connected between the two ends of the lever arm 22, and the other end of the pressure rod 23 is the action end 2301; during the movement of the door body 40 from the open position to the closed position, it acts on the action end 2301 to drive the blocking end 201 to move and unlock the area inside the frame.

[0061] For example, the lower end of the pressure rod 23 is preferably rotatably connected to the midpoint of the lever arm 22. In this embodiment, the length of the pressure rod 23 is less than the length of the stop rod 21, but the rotation center of the lever arm 22 is the end of the lever arm 22 away from the stop rod 21. Thus, the pressure rod 23 is near the rotation center, and the stop rod 21 is far from the rotation center. Therefore, when the pressure rod 23 is pressed down by an external force, the downward stroke of the stop rod 21 is greater than the downward stroke of the pressure rod 23. Because in this embodiment, the pressure plate 42 acts on the top of the pressure rod 23 to drive the lever arm 22 to move the stop rod 21 downward to unlock, the door body 40 can achieve the effect of controlling a large stroke with a small stroke, avoiding the door body 40 directly acting on the stop rod 21 to generate a greater downward movement, and eliminating the need to set more stroke space.

[0062] It should also be noted that the purpose of adding the pressure bar 23 in this embodiment is to allow the action end 2301 of the pressure bar 23 to interact with the door panel 41. Thus, the projection of the pressure plate 42 in the vertical direction covers the action end 2301 without covering the barrier end 201. The barrier end 201 can be used only for blocking, avoiding the risk of collision with external components when the pressure plate 42 presses on the barrier end 201.

[0063] Optionally, the support 10 is provided with a first guide groove 101 on one side of the stop bar 21, which is arranged along the movement direction of the stop bar 21; the blocking assembly 20 also includes a stop bar pin 24 passing through the first guide groove 101, and the lever arm 22 and the stop bar 21 are respectively rotatably connected to the stop bar pin 24.

[0064] In this embodiment, the stop pin 24 is connected to the stop rod 21 and the lever arm 22, and is inserted into the first guide groove 101. The stop pin 24 and the first guide groove 101 guide the movement of the stop rod 21, thereby achieving the stability of the movement of the stop rod 21. Preferably, the stop pin 24 is inserted into the main rod 211.

[0065] Optionally, the support 10 has a second guide groove 102 on one side of the pressure rod 23, arranged along the movement direction of the pressure rod 23; the blocking assembly 20 also includes a pressure rod pin 25 passing through the second guide groove 102, and the lever arm 22 and the pressure rod 23 are rotatably connected to the pressure rod pin 25. Preferably, the pressure rod pin 25 passes through the pressure rod 23.

[0066] In this embodiment, the pressure rod pin 25 is connected to the pressure rod 23 and the lever arm 22 and passes through the second guide groove 102. The stop pin 24 and the second guide groove 102 guide the movement of the pressure rod 23, thereby achieving the stability of the movement of the pressure rod 23.

[0067] More preferably, the lower end of the pressure rod 23 is disposed in the support 10, the first guide groove 101 and the second guide groove 102 are disposed on one side wall of the support 10, and the lever arm 22 is disposed on the outside of the side wall, thereby facilitating the placement of the lever arm 22 outside the support 10 and facilitating the installation of the lever arm 22.

[0068] Optionally, there are two lever arms 22; the two lever arms 22 are arranged opposite to each other on both sides of the pressure bar 23.

[0069] For example, see Figure 3 Both lever arms 22 are disposed outside the support 10. In conjunction with the foregoing, this embodiment preferably provides a first guide groove 101 and a second guide groove 102 on each of the two opposite sidewalls of the support 10. The two ends of the stop pin 24 extend outside the support 10 through one of the first guide grooves 101, and the two lever arms 22 connect to the two ends of the stop pin 24 and the two ends of the pressure pin 25 outside the support 10. This embodiment's technical solution of one stop pin 24 corresponding to two first guide grooves 101 and one pressure pin 25 corresponding to two second guide grooves 102 achieves balanced guidance at both ends of the stop pin 24 and the pressure pin 25, enhancing the stability of the guidance.

[0070] Optionally, the central axes of the stop bar 21 and the pressure bar 23 are arranged parallel to each other, and the plane containing the central axes of the two is defined as the first plane, which is arranged parallel to the front of the door body 40.

[0071] In this embodiment, the spatial position relationship between the stop bar 21 and the pressure bar 23 relative to one side of the door body 40 is defined, and the distance from the central axis of the pressure bar 23 and the central axis of the stop bar 21 to the nearest side of the door body 40 is the same.

[0072] Based on the same utility model concept, see reference Figure 5 and Figure 6 A switch cabinet includes a cabinet body 60, a circuit breaker 70, and an anti-collision door device as described above; the cabinet body 60 is provided with a receiving cavity 601 for housing the circuit breaker 70, and at least one side of the receiving cavity 601 is provided with an opening for installing a door frame 50, and the door body 40 is configured to open or close the opening; a blocking assembly 20 is located outside the door body 40.

[0073] In this embodiment, a switch cabinet with a portable circuit breaker 70 (i.e., the aforementioned external component) is selected, and the cabinet 60 will not be described in detail here.

[0074] This embodiment applies an anti-collision door device to a switch cabinet. The example used is that the pressure plate 42 acts on the actuating end 2301 to drive the stop bar 21. Initially, the door 40 is in the closed position to seal the opening. At this time, the circuit breaker 70 is outside the cabinet 60, and the stop bar 21 locks the passage within the frame. First, the door 40 is opened downwards to the open position. At this time, the pressure bar 23 is acted upon to drive the stop bar 21 downwards until the passage lock is released as described above. Then, the circuit breaker 70 is sent from the opening into the receiving cavity 601.

[0075] Optionally, it also includes a mounting rail 80 for guiding the circuit breaker 70 into and out of the receiving cavity 601; the mounting rail 80 is located in the frame area and arranged along the depth direction of the receiving cavity 601, and the blocking end 201 is configured to block the mounting rail 80 along its length to prevent the circuit breaker 70 from docking to the mounting rail 80 and then entering the receiving cavity 601 through the door frame 50.

[0076] For example, mounting rails 80 are provided on both sides of the receiving cavity 601. The two mounting rails 80 are arranged separately on both sides of the door body 40. One end of the mounting rails 80 extends to the outside of the door body 40. The stop bar 21 can be set on the outside of the door panel 41 near the opening end of the mounting rail 80, so as to realize the blocking function of the stop bar 21 as described above.

[0077] In other embodiments, the stop bar 21 extends from the bottom of the mounting rail 80 to the top of the mounting rail 80.

[0078] Regardless of the type of stop bar 21 used, taking the direction in which the circuit breaker 70 enters the receiving cavity 601 as a reference, it can be seen from the above that the door body 40 is positioned inside the stop bar 21, so that the stop bar 21 can block the circuit breaker 70. In addition, after the door body 40 is fully opened, the circuit breaker 70 is connected to the mounting rail 80 and finally enters the receiving cavity 601.

[0079] The above description is only a partial embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
