Description

Technical Field

[0001] This utility model belongs to the field of switch equipment technology and relates to a structure that satisfies the requirement of having a micro-motion device in the operating hole. Background Technology

[0002] According to the five electrical protection requirements for switchgear, when the handcart inside the switchgear is in the working position, it is strictly forbidden to close the grounding switch, and when the grounding switch is closed, it is strictly forbidden to move the handcart into the working position.

[0003] Currently, emerging switchgear equipment adds an electric propulsion mechanism to the manual propulsion mechanism for the operation of the handcart. The traditional interlocking mechanism is only compatible with the manual propulsion mechanism and cannot provide the five electrical protections for the newly added electric propulsion mechanism. This means that if the operator makes an operational error and fails to pull out the grounding switch operating handle in time, the electric propulsion mechanism can work to push the handcart into the working position, thereby violating the five electrical protection requirements and causing operational hazards. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a structure that satisfies the requirement of having a micro-motion device in the operating hole.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structure with a micro-motion device for an operating hole includes a welded perforated plate, a movable baffle, a tension spring, and a micro switch. The welded perforated plate is fixedly mounted on a door panel, forming a gap between the welded plate and the door panel for the movable baffle to pass through. The two ends of the tension spring are respectively connected to the movable baffle and the door panel to maintain the movable baffle in a set position. The welded perforated plate is provided with a guide hole, and the movable baffle is provided with a limit hole. The welded perforated plate and the micro switch are respectively disposed on opposite sides of the movable baffle in the direction of movement.

[0007] Furthermore, it also includes a bracket, which is fixedly installed on the inside of the door panel, one end of the tension spring is connected to the bracket, and the micro switch is fixedly installed on the bracket.

[0008] Furthermore, a through hole is provided on the door panel, and a lever is provided on the movable baffle, the lever passing through the through hole to the outside of the door panel.

[0009] Furthermore, the limiting hole is configured such that when the movable baffle moves to a set position, the limiting hole communicates with the guide hole and the through hole.

[0010] In summary, the advantages of this utility model are as follows:

[0011] This utility model uses a welded perforated plate, a movable baffle, and a micro switch to form a linkage for the operation of the grounding switch and the operation of the electric propulsion mechanism. The state mode is switched by the movement of the movable baffle. When the movable baffle is aligned with the welded perforated plate so that the operating handle can be inserted to operate the opening and closing of the circuit breaker, the electric propulsion mechanism cannot operate if the micro switch is not triggered. When the movable baffle triggers the micro switch, the electric propulsion mechanism can run. When the movable baffle is misaligned with the welded perforated plate so that the operating handle cannot be inserted, the electrical five-proof requirements for manual operation are met.

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0017] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0018] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0019] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0020] This utility model embodiment provides a structure that satisfies the requirement of having a micro-motion device in the operating hole, which is set at the door panel 1 of the switch cabinet trolley compartment. It is used to link the manual operation of the switch cabinet grounding switch with the electric propulsion mechanism of the trolley, so that when the grounding switch is manually operated, the electric propulsion mechanism of the trolley is terminated and the trolley cannot be pushed into the test position, thus achieving the five electrical protection requirements.

[0021] Specifically, refer to Figure 1 , Figure 2 and Figure 3 A welding perforated plate 2 is provided on the door panel 1 of the handcart compartment. A guide hole 21 for the operating handle to pass through is provided in the middle of the welding perforated plate 2. A through hole 11 is provided on the door panel 1. The welding perforated plate 2 is fixedly provided on the door panel 1 so that the guide hole 21 is aligned and connected with the through hole 11. The guide hole 21 faces the grounding switch in the handcart compartment. The operating handle is guided through the guide hole 21 and passes through the through hole 11 to enter the handcart compartment and connect to the grounding switch, so that the closing and opening operations of the grounding switch can be performed.

[0022] A gap of a predetermined thickness is provided between the welding perforated plate 2 and the door panel 1, allowing a movable baffle 3 to be installed within the gap. The movable baffle 3 is slidably fitted within the gap, allowing it to slide relative to the welding perforated plate 2, moving into and out of the gap. A limiting hole 31 is provided on the movable baffle 3, with a diameter sufficient to allow the operating handle to pass through. During the movement of the movable baffle 3 relative to the welding perforated plate 2, in one predetermined relative position relationship, the limiting hole 31 and the guide hole 21 can be coaxially aligned, allowing the operating handle to pass through simultaneously. In other relative position relationships, the limiting hole 31 and the guide hole 21 are misaligned, preventing the operating handle from passing through.

[0023] Preferably, the welding perforated plate 2 is disposed on the inner side of the door panel 1 relative to the handcart compartment, and the movable baffle 3 is provided with a lever 32. The lever 32 passes through the through hole 11 of the door panel 1 and protrudes to the outer side of the door panel 1, so that the user can adjust the position of the movable baffle 3 from the outside of the handcart compartment by means of the lever 32, so that the limiting hole 31 is aligned with or offset from the guide hole 21.

[0024] Furthermore, a tension spring 33 is also provided on the movable baffle 3. The two ends of the tension spring 33 are connected to the movable baffle 3 and the door panel 1 respectively. When the movable baffle 3 is not subjected to other external forces, the tension spring 33 will maintain the movable baffle 3 in a set position. Preferably, the limiting hole 31 and the guide hole 21 are misaligned in the set position.

[0025] A bracket 4 is also provided on the inner side of the door panel 1. The bracket 4 is fixedly installed on the door panel 1 by bolts or rivets and other connecting parts. A micro switch 5 is provided on the bracket 4. The trigger end of the micro switch 5 is located on the side facing the movable baffle 3. When the movable baffle 3 moves to the set position, the movable baffle 3 contacts and triggers the trigger end of the micro switch 5. Furthermore, the two ends of the tension spring 33 are respectively connected to the movable baffle 3 and the bracket 4.

[0026] The movable baffle 3, under the action of the tension spring 33, keeps the trigger micro switch 5 activated, keeping the electric propulsion mechanism in an active state. At this time, the handcart can move to the test position under the drive of the electric propulsion mechanism, and the limit hole 31 and the guide hole 21 are misaligned, making it impossible to insert the operating handle to perform the grounding switch opening and closing operation. When it is necessary to perform the grounding switch operation, the handcart exits the test position, the user moves the movable baffle 3 to align the limit hole 31 and the guide hole 21, and inserts the operating handle. At this time, the movement of the movable baffle 3 causes the micro switch 5 to open, and then the electric propulsion mechanism stops, making it impossible to drive the handcart to move to the test position, so as to ensure the electrical five-proof requirements when manually operating.

[0027] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
