Description

Technical Field

[0001] This utility model relates to the technical field of electrical switch cabinet bases, specifically a quick-installation base for switch cabinets used in electrical equipment. Background Technology

[0002] In modern power systems, switchgear is the core equipment for power distribution and control. The ease of installation and stability of switchgear directly affect the construction efficiency and operational safety of the power system. To meet the needs of rapid construction and efficient operation and maintenance, existing switchgear quick-installation bases, through structural designs such as snap-fit ​​and bolt quick-connect, can achieve rapid positioning and fixing of switchgear and base, which greatly shortens the installation time and improves the efficiency of engineering construction.

[0003] However, existing quick-installation bases still have significant shortcomings in practical applications. On the one hand, most bases focus on the speed of mechanical connection, using metal materials or lacking insulation design, which cannot effectively isolate the potential conduction between the switch cabinet and the ground. When leakage or insulation failure occurs inside the switch cabinet, the current can easily be conducted to the ground through the base, which may not only cause equipment short circuits and damage, but also pose a serious threat to the personal safety of operators. On the other hand, during the opening, maintenance or fault repair of the switch cabinet, existing bases cannot provide additional insulation protection measures. If operators come into contact with live parts during operation, a current loop can easily be formed through the base connected to the ground, leading to electric shock accidents. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-installation base for switch cabinets used in electrical equipment, which has the advantages of double insulation protection and safety isolation, and solves the problems of lack of base insulation performance and lack of safety protection during maintenance mentioned in the background technology.

[0005] To achieve the aforementioned purpose of double insulation protection and safety isolation, this utility model provides the following technical solution: It includes a base, the outer wall of which is fitted with an insulating plate. A sliding groove is formed through one side of the bottom of the base's inner cavity. A foot pedal is slidably connected to the inner cavity of the sliding groove, and the foot pedal penetrates the base. Swing grooves are formed through both the left and right sides of one side of the insulating plate. A connecting groove is formed between the two swing grooves. A connecting rod is slidably connected inside the connecting groove. Support rods are fixedly connected to both sides of the connecting rod, and the support rods swing within the swing grooves. Two limiting grooves are formed through the upper part of the foot pedal on the side closest to the swing groove. Slide plates are slidably connected to both sides of the inner cavity of the two limiting grooves. A rotating rod is fixedly connected between the two slide plates. The side of the support rod away from the connecting rod is rotatably connected to the middle of the outer wall of the rotating rod.

[0006] As a further embodiment of this utility model: the top of the base is provided with an installation groove, and compression grooves are provided on both sides of the installation groove. A retaining plate is slidably connected to the inner cavity of one side of the compression groove. Limiting plates are fixedly connected to both sides of the retaining plate, and the limiting plates slide in the compression groove. A spring is fixedly connected to one side of the inner cavity of the compression groove, and the other end of the spring is fixedly connected to the retaining plate.

[0007] As a further embodiment of this utility model: a threaded rod is fixedly connected to the base and the insulating plate through the middle of the side of the card plate near the compression groove, and a nut is threadedly connected to the outer wall of the side of the card plate through the insulating plate.

[0008] As a further embodiment of this utility model: a motor is installed on the outer wall of the insulating plate away from the foot pedal, the output end of the motor passes through the insulating plate and the base and is fixedly connected to a lead screw, and the side of the lead screw away from the motor passes through the middle of the foot pedal and is threadedly connected.

[0009] As a further improvement of this utility model: a controller is installed inside the top side of the base, and a control switch is installed on one side of the controller.

[0010] As a further improvement of this utility model: a switch cabinet is provided on the top of the base, a connecting plate is fixedly connected to the bottom of the switch cabinet, and the connecting plate cooperates with the mounting groove. Slots are provided on both sides of the connecting plate, and the slots cooperate with the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the starter motor drives the lead screw to rotate, allowing the foot pedal to slide out smoothly. During the extension process, the support rod, connecting rod one, rotating rod two, and sliding plate work together in a coordinated manner. Through the precise guidance of the connecting groove and the limiting groove, a stable triangular support structure is formed, ensuring the stability of the foot pedal. At the same time, the insulating plate in close contact with the ground plays an isolation role, cutting off the ground potential conduction path and keeping the entire operating platform in an insulated state. When workers stand on it to work, the risk of leakage can be effectively avoided, providing a safe and reliable insulated space for maintenance work and significantly improving the safety and convenience of operation.

[0013] 2. In this utility model, when installing the switchgear, the operator only needs to align the connecting plate at the bottom of the cabinet and insert it vertically into the mounting slot. During the insertion process, the side of the connecting plate will abut against the two side plates, pushing the plates to slide inward along the compression groove, thereby compressing the spring. When the connecting plate is fully embedded in the mounting slot, the plates will quickly rebound under the elastic restoring force of the spring and accurately snap into the slot, thus achieving fast and stable installation of the switchgear. The whole process does not require additional tools, greatly improving assembly efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6In this embodiment of the present invention, a quick-installation base for a switch cabinet for electrical equipment includes a base 1. An insulating plate 2 is fitted onto the outer wall of the base 1. After installation, the insulating plate 2 is tightly fitted to the ground, forming a reliable insulating barrier. This effectively blocks the current conduction path between the switch cabinet 23 and the ground. Even if the switch cabinet 23 experiences a leakage fault, it can prevent current from being conducted to the ground, thereby ensuring the personal safety of the operator and preventing electrical equipment from malfunctioning due to poor grounding. A sliding groove 3 is provided through one side of the bottom of the inner cavity of the base 1, and a foot pedal is slidably connected to the inner cavity of the sliding groove 3. 4. The foot pedal 4 penetrates through the base 1, and the left and right sides of the insulating plate 2 are both penetrated and have swing grooves 5. A connecting groove 6 is provided between the two swing grooves 5. A connecting rod 7 is slidably connected inside the connecting groove 6. Support rods 8 are fixedly connected to both sides of the connecting rod 7, and the support rods 8 swing within the swing grooves 5. Two limiting grooves 9 are provided on the upper part of the side of the foot pedal 4 closest to the swing grooves 5. Slide plates 10 are slidably connected to both sides of the inner cavity of the two limiting grooves 9. A rotating rod 11 is fixedly connected between the two slide plates 10. The side of the support rod 8 away from the connecting rod 7 is rotatably connected to the rotating rod 11. At the middle of the outer wall of the second moving rod 11, during the movement of the foot pedal 4, the mechanical linkage structure drives the support rod 8 to swing within the connecting groove 6. Simultaneously, the first connecting rod 7 slides downward along the connecting groove 6, thereby causing the rotating rod 11 and the sliding plate 10, which are connected to the other end of the support rod 8, to slide within the limiting groove 9. The coordinated movement of multiple components provides stable support for the foot pedal 4, ensuring its stability and reliability during outward extension. Workers can safely stand on the foot pedal 4 to perform various operations and maintenance on the switch cabinet 23. The motor 1 is installed on the outer wall of the insulating plate 2 away from the foot pedal 4. 2. The output end of the motor 12 passes through the insulating plate 2 and the base 1 and is fixedly connected to the lead screw 13. The side of the lead screw 13 away from the motor 12 passes through the middle of the foot pedal 4 and is threaded. The motor 12 drives the lead screw 13 to rotate, driving the foot pedal 4 to slide smoothly outward along the slide groove 3. The top side of the base 1 is equipped with a controller 21. The side of the controller 21 is equipped with a control switch 22. When the switch cabinet 23 needs to be used, debugged, or repaired and maintained, the operator presses the control switch 22. The control signal is transmitted to the motor 12 through the controller 21, and the motor 12 starts running.

[0023] The top of the base 1 has a mounting groove 14, and compression grooves 15 are formed on both sides of the mounting groove 14. A retaining plate 16 is slidably connected to the inner cavity of one side of the compression groove 15. Limiting plates 17 are fixedly connected to both sides of the retaining plate 16 and slide within the compression groove 15. A spring 18 is fixedly connected to one side of the inner cavity of the compression groove 15, and the other end of the spring 18 is fixedly connected to the retaining plate 16. A threaded rod 19 is fixedly connected to the middle of the side of the retaining plate 16 near the compression groove 15, penetrating the base 1 and the insulating plate 2. A nut 20 is threadedly connected to the outer wall of the side of the retaining plate 16 penetrating the insulating plate 2. When disassembling the switch cabinet 23, the operator rotates the nut 20 to drive the threaded rod 19 to slide outward. The movement of the threaded rod 19 drives the retaining plate 16 to disengage from the retaining groove 25, releasing the locking state of the switch cabinet 23. This design makes the disassembly process of the switch cabinet 23 simple and fast. Compared to traditional disassembly methods, this method significantly shortens disassembly time and greatly improves equipment maintenance efficiency. The top of the base 1 is equipped with a switch cabinet 23, and the bottom of the switch cabinet 23 is fixedly connected to a connecting plate 24. The connecting plate 24 cooperates with the mounting groove 14. Both sides of the connecting plate 24 are provided with slots 25, and the slots 25 cooperate with the clamping plates 16. When installing the switch cabinet 23, the operator only needs to align the connecting plate 24 at the bottom of the cabinet and insert it vertically into the mounting groove 14. During the insertion process, the side of the connecting plate 24 will abut against the clamping plates 16 on both sides, pushing the clamping plates 16 to slide inward along the compression groove 15, thereby compressing the spring 18. When the connecting plate 24 is fully embedded in the mounting groove 14, the clamping plates 16 will quickly rebound under the elastic restoring force of the spring 18 and accurately clamp into the slots 25, thereby achieving a fast and stable installation of the switch cabinet 23.

[0024] The working principle of this utility model is as follows: When installing the switch cabinet 23, the operator only needs to align the connecting plate 24 at the bottom of the cabinet and insert it vertically into the mounting groove 14. During the insertion process, the side of the connecting plate 24 will abut against the clamping plates 16 on both sides, pushing the clamping plates 16 to slide inward along the compression groove 15, thereby compressing the spring 18. When the connecting plate 24 is fully embedded in the mounting groove 14, the clamping plate 16 will quickly rebound under the elastic restoring force of the spring 18 and accurately snap into the clamping groove 25, thereby achieving a fast and stable installation of the switch cabinet 23. The whole process does not require additional tools, greatly improving assembly efficiency.

[0025] When the switchgear 23 needs to be used, debugged, or repaired, the operator presses the control switch 22. The control signal is transmitted to the motor 12 through the controller 21. The motor 12 then starts running and drives the lead screw 13 to rotate, driving the foot pedal 4 to slide smoothly outward along the slide groove 3. During the movement of the foot pedal 4, the mechanical linkage structure drives the support rod 8 to swing in the connecting groove 6. At the same time, the connecting rod 7 slides down along the connecting groove 6, which in turn causes the rotating rod 11 and the sliding plate 10 connected to the other end of the support rod 8 to slide in the limiting groove 9. The coordinated movement of multiple components provides a stable support for the foot pedal 4, ensuring that it remains stable and reliable during the outward extension. The staff can safely stand on the foot pedal 4 to perform various operations and repairs on the switchgear 23. It can effectively isolate the ground potential, provide a safe and insulated operating space for the workers, and significantly reduce the risk of electric shock.

[0026] After the operation is completed, press the control switch 22 again. The controller 21 controls the motor 12 to run in reverse, and the lead screw 13 reverses accordingly, accurately retracting the foot pedal 4 into the slide groove 3. At the same time, the related structures that provide support for the foot pedal 4 are also reset and restored to their initial state for easy use later.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
