Description

Technical Field

[0001] This application relates to the field of switchgear technology, and more specifically, to a switchgear cabinet internal switch linkage support device and a switching assembly. Background Technology

[0002] Switchgear, as a core piece of equipment in power systems, is widely used in industrial, commercial, and public utilities for circuit control, protection, and isolation. Externally operated electrical control cabinets, by placing the operating mechanisms outside the cabinet door, significantly improve operator safety and ease of use, and reduce the risk of direct contact with high-voltage components. With the continuous development of power automation technology, switchgear is evolving towards higher reliability, intelligence, and integration to meet the demands of modern power grids for efficient and stable operation, driving the optimization and innovation of equipment design.

[0003] However, the existing technology for connecting switchgear door handles and switch linkages has inherent defects. After repeated use or due to significant vibrations during switch operation, the linkage is prone to loosening and sinking, making it impossible to accurately insert into the keyhole on the door and thus preventing the door from closing. This not only increases maintenance frequency and the risk of operational interruptions but may also delay fault handling in emergencies, affecting the continuity and stability of the power system. The linkage sinking problem is more pronounced in high-frequency operation or vibration environments, requiring operators to repeatedly attempt to close the door, increasing time wastage and potential safety hazards. Furthermore, connection failure due to loosening can trigger cascading failures, such as the door failing to lock, further threatening the safe operation of the equipment. Therefore, the inability to close the door caused by linkage sinking has become a key challenge restricting the reliability and service life of switchgear, urgently requiring solutions to ensure smooth operation and system performance.

[0004] There is currently no effective technical solution to the above problems. Utility Model Content

[0026] Firstly, please refer to Figures 1-2 Some embodiments of this application provide a switch linkage support device inside a switch cabinet, which is installed on the switch cabinet door 1. The switch cabinet door 1 is provided with a keyhole 2 for defining the insertion position of the switch linkage 9. The switch linkage support device inside the switch cabinet includes a support member, which includes an integrally connected mounting part 3 and a support part 4. The mounting part 3 is fixed to the inside of the switch cabinet door 1 and is located below the keyhole 2. The support part 4 includes a first support piece 41 that is inclined upward in the direction away from the switch cabinet door 1 and connected to the mounting part 3 at one end, and a second support piece 42 that is connected to the other end of the first support piece 41 and inclined downward in the direction away from the switch cabinet door 1.

[0027] Specifically, this application introduces a switch linkage support device inside the switch cabinet to effectively solve the problem in the prior art where the switch linkage 9 sinks, causing the cabinet door to fail to close. Through its unique structural design, this device can elastically support and reinforce the switch linkage 9, ensuring that the switch linkage 9 remains in the correct position during operation, thereby significantly improving the operational reliability and service life of the switch cabinet.

[0028] More specifically, the main function of the device in this application is to provide support and positioning for the switch linkage 9, preventing it from sinking or shifting during operation.

[0029] More specifically, the switch cabinet door 1 is a component of the switch cabinet, typically made of metal, used to enclose the electrical components inside and provide an interface for operators to interact with the interior. The keyhole 2 is a specially designed hole on the switch cabinet door 1, its shape and size defining the insertion position and direction of the switch linkage 9. The support component is the core component of the switch linkage support device inside the switch cabinet, its main function being to provide support for the switch linkage 9. The support component can be made of various materials, such as metal, engineering plastics, or composite materials, as long as they provide sufficient strength and elasticity. The mounting part 3 is part of the support component, used to securely fix the support component to the inside of the switch cabinet door 1. The design of the mounting part 3 needs to consider ease of installation and stability after fixing to ensure that the support component does not loosen during long-term use. The support part 4 is another part of the support component, directly responsible for supporting and holding the switch linkage 9. The first support piece 41 and the second support piece 42 are components of the support part 4. They are connected at a specific angle to form a V-shaped or U-shaped support structure. This structure can effectively support and hold the switch linkage 9 inserted from the keyhole 2 by utilizing the elasticity of its joint.

[0030] The device of this application is mounted on the switch cabinet door 1, and the switch cabinet door 1 is provided with a keyhole 2 for defining the insertion position of the switch linkage 9. The keyhole 2 is an essential component of the switch cabinet operation, ensuring that the switch linkage 9 can be guided to the correct operating position. The shape of the keyhole 2 can be circular, square, or irregular, depending on the cross-sectional shape of the switch linkage 9 and the operational requirements. Secondly, the switch linkage support device inside the switch cabinet includes a support member. The support member is the core functional component of this device, and its main function is to provide support for the switch linkage 9. Furthermore, the support member includes an integrally connected mounting part 3 and a support part 4. The mounting part 3 can be designed as a flat plate and fixed to the cabinet door by bolts 6 or rivets; or it can be designed as a structure with snaps or welding points for quick installation. In addition, the mounting part 3 is fixed to the inside of the switch cabinet door 1 and located below the keyhole 2. The position of the mounting part 3 is crucial, as it ensures that the support part 4 can effectively support the switch linkage 9 inserted from the keyhole 2. Finally, the support part 4 includes a first support piece 41, which is inclined upwards in the direction away from the control cabinet door 1 and connected to the mounting part 3 at one end, and a second support piece 42, which is connected to the other end of the first support piece 41 and inclined downwards in the direction away from the control cabinet door 1. The junction of the first support piece 41 and the second support piece 42 elastically supports and holds the switch linkage 9 inserted from the keyhole 2. The first support piece 41 and the second support piece 42 can be formed by bending the same piece of material, or they can be two separate pieces connected by welding, riveting, or bonding. When the switch linkage 9 is inserted, it is elastically supported by the transition junction of the two pieces. This elastic support mechanism effectively absorbs the impact and vibration that may occur to the switch linkage 9 during operation, preventing it from sinking or falling off, thereby ensuring that the switch linkage 9 is always in the correct operating position.

[0031] The switchgear internal switch linkage support device of this application comprises a support member installed inside the switchgear door 1, below the keyhole 2. This support member includes an integrally connected mounting part 3 and a support part 4. The support part 4 consists of an upwardly inclined first support piece 41 and a downwardly inclined second support piece 42, the junction of which elastically supports and holds the switch linkage 9 inserted through the keyhole 2. This design effectively solves the problem in the prior art where the switch linkage 9, due to loosening and sinking, cannot be accurately inserted into the keyhole 2, resulting in the cabinet door being unable to close. By providing stable elastic support, the device of this application ensures the positional accuracy of the switch linkage 9 during operation, significantly improving the reliability and smoothness of switchgear operation, reducing the maintenance frequency and operational interruption risk caused by linkage sinking, thereby improving the continuity and stability of the power system.

[0032] In some preferred embodiments, the support portion 4 retracts from both sides toward the center in a direction away from the cabinet door 1.

[0033] Specifically, the support part 4 shrinks from both sides toward the center, which can be understood as the width or cross-sectional area of ​​the support part 4 gradually decreasing in the direction away from the switch cabinet door 1, which can save the material of the support part 4 while ensuring the support strength and installation stability of the support part 4.

[0034] In some preferred embodiments, the first support piece 41 has an angle of 25-35° with the horizontal plane, and the second support piece 42 has an angle of 15-25° with the horizontal plane.

[0035] Specifically, the first support piece 41 is the part of the support section 4 that is inclined upwards in the direction away from the cabinet door 1. The angle between it and the horizontal plane determines the guiding and supporting force received by the switch linkage 9 during initial insertion. The second support piece 42 is the part of the support section 4 that is inclined downwards in the direction away from the cabinet door 1. The angle between it and the horizontal plane affects the stability and elastic support effect of the switch linkage 9 after it is fully supported. The setting of these angles is intended to ensure that the switch linkage 9 can be effectively guided during insertion and obtain stable support after being supported, while maintaining good elasticity of the support component.

[0036] More specifically, the solution of this application precisely defines the angle between the first support plate 41 and the second support plate 42 and the horizontal plane, so that the switch link 9 can be guided at an optimized angle when inserted into the keyhole 2 and contacting the support part 4. Specifically, the first support plate 41 has an upward tilt angle of 25-35°, providing suitable guidance and initial support force for the initial insertion of the switch link 9, avoiding jamming or shaking of the link due to improper angle during insertion. Subsequently, when the switch link 9 is further inserted and contacts the second support plate 42, the second support plate 42 has a downward tilt angle of 15-25°, which, together with the first support plate 41, forms a moderately elastic V-shaped or U-shaped support structure, ensuring that the switch link 9 can be stably fixed after being fully supported, and allowing necessary small displacements during operation, thereby effectively absorbing operational impacts and preventing the link from falling off or being damaged.

[0037] In some preferred embodiments, the support member is provided with a weight-reducing groove 5.

[0038] Specifically, the weight-reducing groove 5 refers to a recess, hole, or through groove formed on the body of the support component by removing part of the material. This groove is used to reduce the overall weight of the support component while maintaining its necessary structural strength and support function. In practical applications, the weight-reducing groove 5 can be designed in various geometric shapes, such as circular, elliptical, rectangular, polygonal, or irregular shapes, and can be configured as a through hole or a blind hole. The number, size, and distribution of the weight-reducing groove 5 can be optimized according to the specific structure of the support component, the required load-bearing capacity, and the material properties.

[0039] The solution in this application reduces the amount of material used in the support component by setting a weight-reducing groove 5, thereby directly reducing the weight of the support component itself. This reduction in material leads to a lower manufacturing cost for the support component and makes it more convenient to handle and install.

[0040] In some preferred embodiments, the weight reduction groove 5 is located at the connection between the mounting part 3 and the first support piece 41.

[0041] Specifically, the weight-reducing groove 5 is located at the junction of the mounting part 3 and the first support piece 41, i.e., the part where the two structures are connected. In practical applications, this connection can be a transition area, and the weight-reducing groove 5 can be machined in various shapes within this area, for example, by stamping, milling, or injection molding.

[0042] The solution in this application optimizes the local material composition of the support component by placing the weight-reducing groove 5 at the connection between the mounting part 3 and the first support plate 41. This connection is typically an area where structural stress is concentrated, but redundant material may also exist. By setting the weight-reducing groove 5 here, material in some non-critical load-bearing areas can be effectively removed without significantly weakening the overall structural strength and support function of the support component. This achieves both weight reduction of the support component and ensures the connection strength between the mounting part 3 and the first support plate 41, thereby maintaining the stable and elastic support of the switch linkage 9 by the support component.

[0043] In some preferred embodiments, the mounting part 3 is fixed to the inside of the switch cabinet door 1 by a plurality of bolts 6.

[0044] Specifically, the use of multiple bolts 6 is intended to provide multi-point support and fixation to ensure that the mounting part 3 can maintain a stable position and support capacity during long-term use, especially under repeated insertion and removal of the switch linkage 9.

[0045] The solution proposed in this application effectively solves the problem of insufficient stability that may be caused by a single or unclear fixing method by using multiple bolts 6 to fix the mounting part 3. The synergistic effect of multiple bolts 6 creates multiple stress points between the mounting part 3 and the inside of the switch cabinet door 1, thereby significantly enhancing the connection's firmness and seismic resistance. This fixing method can effectively prevent the mounting part 3 from loosening, displacing, or falling off under conditions such as repeated insertion and removal of the switch linkage 9 or external vibration, ensuring that the supporting device is always in the preset working position, thus guaranteeing the accurate insertion and reliable support of the switch linkage 9.

[0046] In some preferred embodiments, the highest point of the support portion 4 is higher than the lowest point of the keyhole 2 and lower than or level with the center height of the keyhole 2.

[0047] Specifically, the highest point of the support part 4 is higher than the lowest point of the keyhole 2. This means that when the support part 4 supports the switch linkage 9, its highest position ensures that the switch linkage 9 is effectively contacted and guided in the initial stage of entering the keyhole 2. This helps prevent the switch linkage 9 from falling due to gravity during insertion, thus avoiding collision or jamming with the lower edge of the keyhole 2. The lowest point of the keyhole 2 can be understood as the lowest vertical position of the lower edge of the keyhole 2. Simultaneously, the highest point of the support part 4 is lower than or level with the center height of the keyhole 2. This means that when the support part 4 supports the switch linkage 9, its highest position will not obstruct the complete insertion of the switch linkage 9 and can guide the switch linkage 9 towards the center position of the keyhole 2. The center height of the keyhole 2 can be understood as the midpoint position in the vertical direction of the keyhole 2. In practical applications, the fact that the highest point of the support part 4 is level with the center height of the keyhole 2 means that the support part 4 can guide the switch linkage 9 to the vicinity of the central axis of the keyhole 2, thereby providing favorable conditions for the precise cooperation between the switch linkage 9 and the switch component 7.

[0048] The solution proposed in this application solves the problems of inaccurate positioning and insertion difficulties that may occur when the switch link 9 is inserted into the keyhole 2 by precisely defining the relative vertical position of the highest point of the support part 4 and the keyhole 2. Specifically, the setting of the highest point of the support part 4 being higher than the lowest point of the keyhole 2 ensures that the switch link 9 can be effectively supported and guided by the support part 4 as soon as it enters the keyhole 2, avoiding the free fall of the switch link 9 and friction or jamming with the lower edge of the keyhole 2. At the same time, the setting of the highest point of the support part 4 being lower than or level with the center height of the keyhole 2 ensures that the support part 4 provides support without hindering the further insertion of the switch link 9, and guides the switch link 9 to be smoothly inserted along the central axis of the keyhole 2, thereby ensuring the accurate fit between the switch link 9 and the switch component 7. It is precisely because of this precise vertical positioning that the insertion process of the switch link 9 is smoother and more efficient.

[0049] In some preferred embodiments, the keyhole 2 is provided with a limiting groove 21 that limits the insertion posture of the switch linkage 9.

[0050] Specifically, the limiting groove 21 can be understood as a structure provided inside or on the edge of the keyhole 2 to guide and constrain the insertion direction and angle of the switch link 9. For example, the keyhole 2 can be designed as a non-circular hole, such as an irregularly shaped hole with a specific keyway, or a protrusion or groove matching the shape of the switch link 9 can be provided on the inner wall of the keyhole 2. The purpose is that when the switch link 9 is inserted, it can only pass smoothly through the keyhole 2 and cooperate with the support when its posture is completely matched with the shape of the limiting groove 21, thereby avoiding misinsertion or oblique insertion of the switch link 9.

[0051] The solution in this application provides a limiting groove 21 in the keyhole 2, which physically constrains the switch linkage 9 during insertion. When the posture of the switch linkage 9 does not match the limiting groove 21, it cannot be fully inserted or will be blocked, thus forcing the operator to adjust the posture of the switch linkage 9 until it conforms to the shape of the limiting groove 21. It is precisely because of this forced posture constraint that the switch linkage 9 can enter the switch cabinet in the preset correct direction and angle, and accurately align with the support part 4 of the support component, thereby achieving reliable elastic support and reinforcement.

[0052] Secondly, please refer to Figure 3 Some embodiments of this application also provide a switch cabinet opening and closing assembly, which includes a switch component 7, a handle 8, a switch linkage 9, and a switch linkage support device inside the switch cabinet as provided in the first aspect. The handle 8 is fixed on the switch cabinet door 1 and has a keyhole 2. The switch component 7 is installed inside the switch cabinet, and the switch linkage 9 can be connected to the switch component 7 by passing through the keyhole 2 and being supported by the support device.

[0053] Specifically, the switching assembly refers to a complete set of mechanisms in the switchgear used to realize the opening and closing operations of the switch element 7. Its core lies in controlling the movement of the switch element 7 by operating the handle 8 to drive the switch linkage 9. The reliability of this assembly directly affects the normal operation of the switchgear and the safety of the power system. The switch element 7 is an electrical device installed inside the switchgear, such as a circuit breaker, disconnector, or load switch, whose main function is to control the on / off state of the circuit. The handle 8 is an operating component located outside the switchgear door 1, allowing for manual operation by the operator. The handle 8 is usually connected to the switch linkage 9, transmitting operating force to the switch linkage 9 through rotation or pushing / pulling actions. The switch linkage 9 is a mechanical transmission component connecting the handle 8 and the switch element 7, its function being to transmit the operating action of the handle 8 to the switch element 7, enabling remote control of the switch element 7.

[0054] The switchgear opening and closing assembly proposed in this application is implemented in various switchgear environments that require operation via the switch linkage 9. This assembly is typically installed on the switchgear door 1 and inside the switchgear, working in conjunction with the keyhole 2 on the door and the switch linkage 9 to form a reliable switch operating system.

[0055] The unique feature of this application is that the switch linkage 9 can connect with the switch component 7 by passing through the keyhole 2 and being supported by the support member. This means that after the switch linkage 9 is inserted into the keyhole 2, its end is elastically supported by the support member, effectively preventing it from sinking or shifting. This elastic support mechanism ensures precise alignment and reliable connection between the switch linkage 9 and the switch component 7, maintaining stability even under frequent operation or vibration environments. For example, when the switch linkage 9 is inserted, its own weight causes it to fall into the support portion 4 of the support member and is supported upward by the elastic force provided by the junction of the first support piece 41 and the second support piece 42, thereby maintaining it at a preset height and position.

[0056] The switchgear opening / closing assembly proposed in this application utilizes a support device to elastically support and reinforce the switch linkage 9, ensuring that the switch linkage 9 remains in the correct operating position after passing through the keyhole 2. This overcomes the inherent defect in the prior art where the switch linkage 9 sinks, preventing the door from closing. Compared to relying solely on the engagement between the handle 8 and the switch linkage 9, the solution in this application provides an additional, stable support point, significantly improving the reliability and smoothness of the connection between the switch linkage 9 and the switch component 7. Therefore, the opening / closing assembly of this application not only improves the operating efficiency and safety of the switchgear but also extends the service life of the equipment, providing a more reliable guarantee for the stable operation of the power system.

[0057] In some preferred embodiments, the handle 8 is fixed to the switch cabinet door 1 by a plurality of bolts 6, and the mounting part 3 is fixed to the inside of the switch cabinet door 1 by a plurality of bolts 6 located at the bottom of the handle 8.

[0058] Specifically, the handle 8 is fixed to the switch cabinet door 1 by multiple bolts 6, which typically pass through and are tightened from the outside of the door. The mounting part 3 is fixed to the inside of the switch cabinet door 1 by sharing multiple bolts 6 located at the bottom of the handle 8. This means that the bolts 6 used to fix the handle 8, after passing through the switch cabinet door 1, can also be used to fix the mounting part 3 of the switch linkage support device inside the switch cabinet. In this way, a structural connection is formed between the mounting part 3 and the handle 8, allowing both to be installed synchronously using the same set of fasteners.

[0059] The solution proposed in this application effectively integrates the installation process of two independent components into a single coordinated operation by using the same set of bolts 6 for fixing the handle 8 and the mounting part 3. When the handle 8 is fixed to the switch cabinet door 1 by the bolts 6, these bolts 6 naturally pass through the cabinet door and extend to the inside. At this time, the mounting part 3 can be directly aligned with the holes of these bolts 6 and simultaneously tightened using these bolts 6. This avoids drilling separate holes for the mounting part 3 or using additional fasteners, thereby simplifying the overall assembly process.

[0061] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
