Description

Technical Field

[0001] The utility model relates to the technical field of crank hole padlocks, and specifically relates to a side-sliding open-close padlock device for the crank hole of a circuit breaker. Background Technique

[0002] At present, the locking device for the crank hole of high-voltage circuit breakers in China is a safety device used to prevent unauthorized personnel from operating the circuit breaker. This device is usually installed on the crank hole of the circuit breaker to lock the crank hole and achieve material isolation, thereby preventing the circuit breaker from being misoperated.

[0003] The specific design and working method of the locking device may vary depending on different manufacturers and models. Some locking devices may require the use of special tools or electromagnetic keys to open, while some may use technologies such as electronic passwords and mechanical padlocks.

[0004] Using the locking device for the crank hole of high-voltage circuit breakers is an important safety measure, which can ensure the safe operation of the circuit breaker and prevent accidents caused by misoperation or illegal operation. Therefore, when installing and operating high-voltage circuit breakers, appropriate locking devices should be ensured to be used, and relevant safety operation procedures should be strictly followed.

[0005] Traditional locking devices for the crank hole of high-voltage circuit breakers generally use electromagnetic locks or electronic password locks, among which:

[0006] (1) The electromagnetic lock for the crank hole of high-voltage switchgear circuit breakers is a locking device designed based on the electromagnetic principle. Its working principle is that when the electromagnet is energized, a magnetic field is generated to attract the locking tongue to achieve the locking function; when the electromagnet is de-energized, the magnetic field disappears, and the locking tongue returns to its original position under the action of the return spring to achieve unlocking. This locking method has the characteristics of fast speed and reliability and is widely used in the safety protection of high-voltage switchgear.

[0007] However, in the actual use process, the disadvantages of the electromagnetic lock for the crank hole of high-voltage switchgear circuit breakers mainly include:

[0008] Reliability issues: Since the electromagnetic lock, voltage-dividing porcelain bottle sensor, and wire may all be damaged, this will affect its reliability. In addition, it requires external power supply, which may also affect its reliability;

[0009] Complex structure: Compared with other locks, such as mechanical interlocks and mechanical program locks, the structure of the electromagnetic lock is more complex, so the manufacturing and maintenance costs may be higher;

[0010] Safety issues: Although the electromagnetic lock is designed to improve safety, due to its possible damage and the need for external power supply, this may cause safety problems. For example, if the electromagnetic lock is damaged or the power supply is interrupted, it may lead to unauthorized personnel being able to operate the circuit breaker, thereby causing accidents.

[0011] (2) The core of the electronic password lock lies in the application of cryptography principles. By adopting encryption algorithms and key management, it ensures that only authorized personnel can access and operate the high-voltage switchgear. At the same time, the password lock also adopts various security mechanisms, such as password trial limit, password change prompt, etc., to prevent password leakage and unauthorized access.

[0012] However, in the actual use process, the main disadvantages of the electronic password lock for the breaker crank hole of the high-voltage switchgear include:

[0013] 1. High complexity: The electronic password lock needs to complete the operation of the lock through multiple steps such as mechanical action, electronic conversion, and electronic control. Compared with traditional mechanical locks, its complexity is higher;

[0014] 2. Relatively high failure probability: Since the electronic password lock involves electronic devices, once the electronic devices fail, it may cause the lock to malfunction. In addition, if the password system fails, it may also cause the lock to be unable to be opened or closed;

[0015] 3. Security risks: If there are problems in the design or installation of the electronic password lock, it may lead to password leakage or being maliciously attacked, thus bringing potential safety hazards;

[0016] 4. Dependence on power supply: The electronic password lock requires power supply. If the power supply is interrupted or fails, it may cause the lock to malfunction.

[0017] In addition, the following disadvantages exist when using the simple mechanical padlock for the high-voltage switchgear adopted in the earlier stage:

[0018] 1. Poor versatility and inability to fully adapt to the breaker crank hole positions of most high-voltage switchgears;

[0019] 2. Simple design, designed to open outward, and the shaft position is prone to deformation or cause mechanical injury to the staff.

[0020] Therefore, this application specifically proposes a side-sliding open-close padlock device for the breaker crank hole to solve the above technical problems. Utility Model Content

[0021] The main purpose of this utility model is to provide a side-sliding open-close padlock device for the breaker crank hole to solve the above technical problems.

[0032] The first wedge block is movably arranged in the positioning through hole, and the inclined surface of the first wedge block always faces the movable cover plate.

[0033] Furthermore, the first latch assembly further includes a support plate arranged on the bottom plate. The support plate is located between the movable support plate and the bottom plate and is used to prevent the first wedge block from directly colliding with the bottom plate.

Specific embodiments

[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0055] Embodiment 1.

[0056] For this embodiment part, please refer in detail to Figures 1 to 4 .

[0057] In the prior art, referring to Figure 2 and Figure 3 , a conventional circuit breaker winding handle hole padlock device is arranged on the base plate 1. A winding handle hole main body 11 aligned with the winding handle socket is opened on the base plate 1 for accessing the winding handle to drive the circuit breaker trolley to move.

[0058] At this time, a knob 12 is arranged on the base plate 1, a plate body activity groove 13 communicating with the winding handle hole main body 11 is arranged inside the base plate 1, a movable plate 15 is arranged inside the plate body activity groove 13, the knob 12 is connected to the connecting shaft 14, and the connecting shaft 14 is connected to the top end of the movable plate 15. Therefore, when the knob 12 rotates, it can drive the movable plate 15 to rotate in the plate body activity groove 13 through the connecting shaft 14, controlling the communication of both ends of the winding handle hole main body 11, that is, it can also be used to complete the switching between the communication state and the blocking state of both ends of the winding handle hole main body 11 when the movable plate 15 rotates.

[0059] However, it should be noted that when the two ends of the crank handle hole body 11 are in a communicating state, since there is generally no limiting structure to limit the position and state of the movable plate 15 when the movable plate 15 rotates, under the working state of the crank handle rotation, the movable plate 15 affected by gravity will strike and collide with the crank handle, causing wear.

[0060] Based on the prior art, referring to Figure 1 and Figure 2 , the present utility model provides a side-sliding open-close padlock device for a circuit breaker crank handle hole, including:

[0061] Two groups of limiting slide rails 2, which are arranged horizontally and parallel to each other on the bottom plate 1;

[0062] A cover plate assembly 3, including a movable cover plate 34 that slidably covers the front part of the crank handle hole body 11. The movable cover plate 34 is limited and slid along the horizontal direction on the bottom plate 1 through two groups of limiting slide rails 2, and the movable cover plate 34 is driven and fixed through a padlock assembly and a locking assembly 6;

[0063] A transmission assembly 5, which is arranged on the bottom plate 1 and connects the cover plate assembly 3 and the knob 12, and is used to drive the movable cover plate 34 to slide when the knob 12 rotates.

[0064] Under normal conditions, the movable cover plate 34 covers the front part of the crank handle hole body 11. At this time, the padlock assembly can control the position of the movable cover plate 34 to be fixed. While preventing the movable cover plate 34 from sliding, the transmission assembly 5 can also prevent the knob 12 from rotating. Therefore, by setting the transmission assembly 5, while the knob 12 rotates, the movable cover plate 34 is driven to move, and the double physical protection of the crank handle hole can be completed by using the movable cover plate 34.

[0065] When the knob 12 rotates, the crank handle hole body 11 is communicated. At this time, the transmission assembly 5 can drive the movable cover plate 34 to move along the length direction of the limiting slide rail 2. After moving to a specified position, the locking assembly 6 can drive the position of the movable cover plate 34 to be fixed. Therefore, at this time, the locking assembly 6 can be used to control the position of the movable cover plate 34 to be fixed when the crank handle hole is in an open state, thereby avoiding the movable plate 15 from sagging and colliding with the crank handle under the influence of gravity, resulting in mutual wear between the movable plate 15 and the crank handle. While protecting the device structure, it is also convenient to use the gravity of the movable plate 15 to drive the movable cover plate 34 to quickly move and cover the crank handle hole when the locking of the locking assembly 6 is cancelled, improving the operation efficiency.

[0066] In summary, by designing the side-sliding cover plate structure here, it can effectively prevent unauthorized personnel from accidentally operating or illegally operating the circuit breaker of the high-voltage switchgear. At the same time, due to the setting of side-sliding limits, it can quickly open the protective cover of the circuit breaker crank handle hole, enabling the operator to quickly operate when needed and avoiding repeated actions. Compared with traditional mechanical padlocks, electronic password locks, and electromagnetic locks, the structure of this device is more concise and practical, and the operation is convenient. It can be independent of programs, high-integrated circuits, and power supplies, and does not damage the original 6kV high-voltage switchgear circuit breaker crank handle cabinet door, realizing the physical isolation of electric energy at the crank handle hole part.

[0067] In addition, it can also be supplemented that during the specific use process, safety warning slogans can be printed on the moving cover plate 34, which can more effectively remind the operator and surrounding personnel to pay attention to the importance and risks of the operation and enhance safety awareness.

[0068] In addition, it can also be supplemented that except for the parts not specifically mentioned, other parts of this device whose specific materials are not described adopt materials of 3D printing stereolithography technology. Therefore, the structure of this device has the advantages of sufficient strength, light weight, anti-static, and color matching the equipment.

[0069] Furthermore, the padlock assembly includes a first padlock plate 32 provided at one end of the moving cover plate 34 and a second padlock plate 4 provided on the bottom plate 1. The second padlock plate 4 is located on the moving path of the moving cover plate 34;

[0070] A first lock hole 33 and a second lock hole 41 are respectively provided on the first padlock plate 32 and the second padlock plate 4. The first lock hole 33 and the second lock hole 41 are coaxial, and when the first padlock plate 32 and the second padlock plate 4 are in a mutually attached state, the first lock hole 33 and the second lock hole 41 cooperate with each other for padlocking.

[0071] At this time, by setting coaxial lock holes at one end of the moving cover plate 34 and on the bottom plate 1, it is allowed to use a mechanical padlock for fixation, enhancing the safety protection level of the device and ensuring that only authorized personnel can operate the circuit breaker by unlocking.

[0072] Furthermore, the transmission assembly 5 includes a gear main body 51, a rack main body 52, and a rack bracket 53. The gear main body 51 meshes with the rack main body 52. The rack main body 52 is installed on the moving cover plate 34 through the rack bracket 53. The gear main body 51 is provided on the connecting shaft 14, and the gear main body 51 is coaxially driven to rotate with the connecting shaft 14 through the knob 12.

[0073] Here, the gear-rack meshing is a conventional meshing operation, and specific requirements for the number of gears are not made here, and it can be adjusted correspondingly according to the actual use status on site.

[0074] Furthermore, a handle 31 needs to be provided on the movable cover plate 34 for an operator to manually control the movement of the movable cover plate 34 along the length direction of the limit slide rail 2.

[0075] In specific situations, the movement of the movable cover plate 34 can also be manually driven to further cooperate with the transmission component 5 to control the rotational movement of the movable plate 15, completing the connection of both ends of the crank hole body 11, so as to ensure the normal operation of the operation. Therefore, by manually controlling the movement of the movable cover plate 34 at this time, a new driving method can be provided for the connection control of the crank hole in some special situations (such as the detachment of the knob 12 part, etc.), ensuring the normal use of the device.

[0076] Furthermore, referring to Figure 4 , the locking component 6 includes a cylindrical block 61 provided on the bottom plate 1 and a cylindrical slot 62 opened on the back of the movable cover plate 34, and the cylindrical block 61 is movably engaged with the cylindrical slot 62.

[0077] It should be noted that the cylindrical slot 62 is located at one end of the movable cover plate 34, and both the cylindrical block 61 and the movable cover plate 34 here are elastic plastic structures or elastic metal structures with a certain degree of deformation. The material part is not limited here.

[0078] Therefore, in specific implementation, when the movable cover plate 34 moves to a specified position, the cylindrical block 61 can have a certain amount of deformation and expansion when contacting the movable cover plate 34, ensuring that the cylindrical block 61 can be normally engaged and connected with the cylindrical slot 62 finally, and can also deform when the movable cover plate 34 is forced to move, ensuring its normal detachment.

[0079] Embodiment Two.

[0080] Based on the above Embodiment One, Embodiment Two is proposed to supplement and illustrate another use structure of the locking component 6. For details, refer to Figure 5 .

[0081] A side-sliding open-close padlock device for a circuit breaker crank hole. Based on the above Embodiment One, different from the above embodiment, the locking component 6 adopts other structures, such as Figure 5 as shown, the locking component 6 includes a magnetic attraction block 63 embedded in the bottom plate 1 and a metal part 64 embedded in the back of the movable cover plate 34, and the magnetic attraction block 63 is magnetically connected to the metal part 64.

[0082] In specific implementation, when the magnetic attraction block 63 contacts the metal part 64, the magnetic attraction block 63 can be used to control the position of the movable cover plate 34 to be fixed, and when the movable cover plate 34 is subjected to a certain large force, it can ensure the separation of the magnetic attraction block 63 and the metal part 64, ensuring the normal movement of the movable cover plate 34.

[0083] It should be noted that the metal part 64 here should be a magnetically attractable metal structure, and the magnetic attraction block 63 can also be modified into an externally controllable electromagnetic structure.

[0084] Embodiment III.

[0085] Based on the above Embodiment I, Embodiment III is proposed to supplement and illustrate another use structure of the locking component 6. For details, please refer to Figure 6 and Figure 7 .

[0086] A side-sliding open-close padlock device for the breaker crank hole. Based on the above Embodiment I, different from the above embodiment, the locking component 6 adopts other structures, such as Figure 6 and Figure 7 As shown, the locking component 6 is set as the first clamping block component 65. The first clamping block component 65 includes a positioning through hole 652 opened on the moving cover plate 34, a movable support plate 653, a first wedge-shaped block 654 arranged at one end of the movable support plate 653, and a return hinge 656 arranged at the other end of the movable support plate 653. The return hinge 656 is arranged on the bottom plate 1 and is used to drive the first wedge-shaped block 654 at one end of the movable support plate 653 to be forced to fit against the bottom plate 1.

[0087] At this time, it should be added that the first wedge-shaped block 654 is movably arranged in the positioning through hole 652, and the inclined surface of the first wedge-shaped block 654 always faces the moving cover plate 34.

[0088] In specific implementation, when the moving cover plate 34 moves, after the first wedge-shaped block 654 contacts the moving cover plate 34, the movable support plate 653 elastically moves. The first wedge-shaped block 654 moves on the surface of the moving cover plate 34 until the first wedge-shaped block 654 falls into the positioning through hole 652. After that, when the moving cover plate 34 needs to move, pull the movable support plate 653 to move the first wedge-shaped block 654 out of the positioning through hole 652.

[0089] It can be added that the return hinge 656 here can be regarded as a set of hinge structures and an internal torsion spring structure. The torsion spring structure is used to drive the hinge structure to rotate, so as to ensure that the movable support plate 653 is continuously stressed, and the first wedge-shaped block 654 is always stressed and the stress direction is towards the bottom plate 1.

[0090] Furthermore, the first clamping block component 65 further includes a frame plate 655 arranged on the bottom plate 1. The frame plate 655 is located between the movable support plate 653 and the bottom plate 1 and is used to prevent the first wedge-shaped block 654 from directly colliding with the bottom plate 1.

[0091] It can be added that the frame plate 655 here can also be used to ensure that there is enough space between the movable support plate 653 and the bottom plate 1, which is convenient for the operator to manually pull the movable support plate 653.

[0092] Further, the first card block assembly 65 further includes a groove body 651 provided at one end of the movable cover plate 34, and the positioning through hole 652 is located within the groove body 651;

[0093] During the movement of the movable cover plate 34, the groove body 651 is used to contact the first wedge block 654, and the inclined surface of the first wedge block 654 slides within the groove body 651 until it enters the positioning through hole 652.

[0094] It can be supplemented that the groove body 651 here can ensure that the first wedge block 654 smoothly enters and slides on the surface of the groove body 651, thereby improving the efficiency of the first wedge block 654 entering the positioning through hole 652.

[0095] Embodiment Four.

[0096] Based on the above Embodiment One, Embodiment Four is proposed to supplement and illustrate another use structure of the locking assembly 6. For details, see Figure 8 .

[0097] A side-sliding open-close padlock device for the breaker crank hole. Based on the above Embodiment One, different from the above embodiment, as Figure 8 shown, the locking assembly 6 adopts another structure. The locking assembly 6 is set as the second card block assembly 66. The second card block assembly 66 includes a positioning hole 661 provided on the back of the movable cover plate 34, a frame body movable groove 662 located inside the plate body of the bottom plate 1, a spring 663, a rotating shaft 664, a second wedge block 665, a connecting bracket 666 and a pressing structure. One end of the connecting bracket 666 is rotatably arranged in the frame body movable groove 662 through the rotating shaft 664.

[0098] Specifically, the spring 663 is connected to drive the other end of the connecting bracket 666 to be close to the movable cover plate 34. The pressing structure is arranged on the bottom plate 1 and is connected to the connecting bracket 666. A pressing groove 669 is provided on the bottom plate 1 for limiting the movement of the pressing structure.

[0099] At the same time, a second wedge block 665 is provided at the other end of the connecting bracket 666. The second wedge block 665 is movably arranged in the positioning hole 661, and the inclined surface of the second wedge block 665 is always aligned with the movable cover plate 34.

[0100] In specific implementation, when the movable cover plate 34 moves, the second wedge block 665 contacts the back of the movable cover plate 34 and then elastically moves in an arc around the rotating shaft 664 by using the connecting bracket 666 and the spring 663. The second wedge block 665 moves on the surface of the back of the movable cover plate 34 until the second wedge block 665 falls into the positioning hole 661. After that, when the movable cover plate 34 needs to move, push the pressing structure to move the first wedge block 654 out of the positioning through hole 652.
