Description

[0002] During the operation of power equipment in a substation, the display and operating mechanisms, switching switches, operating buttons, and operating holes of the protection devices or measurement and control devices on the existing switch cabinets or protection and automation cabinets need to be isolated and locked for safety reasons to prevent accidents caused by misoperation. However, existing isolation and locking devices include those that lock a single device and those that lock an entire device. Often, the entire isolation and locking device is installed on the switch cabinet or protection and automation cabinet. After installation and fixation, the isolation and locking device is in an undetachable state. When isolation and locking are not required, it is very inconvenient to operate the power equipment, and the isolation and locking device may even interfere with normal equipment operation. In addition, existing isolation and locking devices also have the following problems: there are technical problems such as a large number of individual devices required to be locked and inconsistent locking positions; the overall locking device adopts an overall fixing method, and the switch cabinet or protection and automation cabinet covers multiple or all operating devices on the switch cabinet or protection and automation cabinet, which affects some operating devices that should not be isolated and locked, and seriously affects normal equipment operation.

[0043] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0045] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0046] In order to solve the problems of poor performance and unreliability of isolation and locking devices in the prior art, the present application provides an isolation and locking device.

[0047] like Figure 1 and Figure 2 As shown, the isolation locking device in the present application includes: an isolation panel 10, a locking shaft 30, a locking seat 40 and a limiting mechanism 50; the isolation panel 10 is used to shield and protect the equipment to be isolated on the electrical equipment; the first end of the locking shaft 30 is connected to the isolation panel 10, and the second end of the locking shaft 30 is connected to the locking seat 40; the locking seat 40 can be fixedly set on the electrical equipment, and the locking seat 40 has a connecting portion 41 for the locking shaft 30 to extend into, and the part of the second end of the locking shaft 30 extending into the connecting portion 41 is provided with a locking portion 31; the limiting mechanism 50 is movably connected to the locking seat 40, and the limiting end of the limiting mechanism 50 can enter the locking portion 31 to lock the locking shaft 30 and the locking seat 40, thereby limiting the locking shaft 30 from escaping from the connecting portion 41.

[0048] When using the isolation and locking device of the above structure, the isolation panel 10 can be used to isolate and protect the equipment to be isolated due to the presence of the partition panel, thereby preventing operators from erroneously operating the equipment to be isolated. Furthermore, because the isolation and locking device also includes a locking shaft 30 and a limiting mechanism 50, the locking shaft 30 and the limiting mechanism 50 cooperate to restrain the second end of the locking shaft 30 within the connecting portion 41. Alternatively, after the limiting mechanism 50 engages and locks the locking shaft 30 and the locking seat 40, the second end of the locking shaft 30 can be released from the connecting portion 41, thereby releasing the isolation panel 10 from the isolation protection of the equipment to be isolated, allowing the equipment to be operated.

[0049] Optionally, the locking shaft 30 and the locking seat 40 are detachably pluggable, so that the locking shaft 30 can be inserted into or withdrawn from the connecting portion 41. That is, in the present application, the second end of the locking shaft 30 can be detached from the locking seat 40. When the isolation locking device is needed to isolate and protect the equipment to be isolated, after the isolation panel 10 is placed on the equipment to be isolated, the second end of the locking shaft 30 is inserted into the interior of the locking seat 40, and the locking shaft 30 and the locking seat 40 are locked under the limiting action of the limiting mechanism 50, thereby achieving isolation and protection of the equipment to be isolated.

[0050] In a specific embodiment of the present application, the cross-section of the second end of the locking shaft 30 is one of an ellipse, a polygon, and a combination of an arc and a straight line, so as to limit the axial rotational freedom of the locking shaft 30 .

[0051] Optionally, the locking portion 31 is a locking groove and / or a locking hole, which is provided on the side wall of the locking shaft 30. With this arrangement, after the limiting structure enters the locking groove or the locking hole, the rotation of the locking shaft 30 can be effectively restricted or the second end of the locking shaft 30 can be restricted from being dislodged from the connecting portion 41.

[0052] Preferably, there are multiple locking grooves and / or locking holes, and the multiple locking grooves and / or locking holes are arranged at intervals along the axial direction of the locking shaft 30 .

[0053] In a specific embodiment of the present application, the inlet end of the connecting portion 41 has a stopper 411, and the outer periphery of the locking shaft 30 has an abutment 32. The locking shaft 30 is inserted into the connecting portion 41 so that the abutment 32 abuts against the stopper 411. This arrangement effectively limits the depth to which the locking shaft 30 can be inserted into the connecting portion 41.

[0054] Preferably, the stopping portion 411 is a stopping step surface, and the abutting portion 32 is a stopping flange.

[0055] Optionally, the limiting mechanism 50 is pivotally or slidably connected to the locking seat 40, so that the limiting mechanism 50 has a first position and a second position; in the first position, the limiting end of the limiting mechanism 50 can enter the locking portion 31 to lock the locking shaft 30 with the locking seat 40; in the second position, the limiting end of the limiting mechanism 50 is disengaged from the locking portion 31, releasing the lock between the locking shaft 30 and the locking seat 40. In a specific embodiment of the present application, the limiting mechanism 50 is pivotally connected to the locking seat 40.

[0056] In the present application, the locking seat 40 is provided with a locking assembly 60 for locking the limiting mechanism 50. When the limiting mechanism 50 is in the first position and locks the locking shaft 30 and the locking seat 40, the device to be isolated is under the isolation protection of the isolation locking device. The locking assembly 60 can lock the limiting mechanism 50, so that the limiting mechanism 50 cannot be switched from the first position to the second position when locked. This effectively ensures that the operator cannot remove the isolation locking device from the device to be isolated without obtaining the unlocking authority of the locking assembly 60, and thus cannot operate the device to be isolated.

[0057] Optionally, the locking assembly 60 is a fixed lock, the fixed lock and the locking seat 40 are designed as an integrated structure, and the fixed lock and the limiting mechanism 50 have a locking and limiting connection position.

[0058] Optionally, the limiting mechanism 50 is a locking tongue mechanism of a fixed lock, and the tongue end of the locking tongue mechanism can enter the locking portion 31 to lock the locking shaft 30 .

[0059] Optionally, the limiting mechanism 50 has a locking end that cooperates with the locking tongue mechanism of the fixed lock, and the locking tongue mechanism extends into the locking end and locks the limiting mechanism 50, so that the limiting end of the limiting mechanism 50 is in a locking position with respect to the locking portion 31.

[0060] In a specific embodiment of the present application, the locking assembly 60 is a padlock, the locking seat 40 and / or the limiting mechanism 50 has a locking hole, and the padlock locks the limiting mechanism 50 through the locking hole, so that the limiting end of the limiting mechanism 50 is in a locking position relative to the locking portion 31.

[0061] In a specific embodiment of the present application, the locking seat 40 includes a seat body 42 and a locking plate 43. The seat body 42 has a connecting portion 41; the locking plate 43 is fixed to the seat body 42 and has a first locking hole 431. The limiting mechanism 50 has a second locking hole 51 and is pivotally connected to the seat body 42. After the limiting end of the limiting mechanism 50 is inserted into the locking portion 31, the first locking hole 431 aligns with the second locking hole 51. With this arrangement, after the limiting mechanism 50 locks the locking shaft 30 and the locking seat 40, the locking assembly 60 can be inserted through the first locking hole 431 and the second locking hole 51 respectively to lock the limiting mechanism 50, thereby preventing the limiting mechanism 50 from switching from the first position to the second position.

[0062] Preferably, there are two locking plates 43, spaced apart to form a movable gap, within which the limiting mechanism 50 is located. This arrangement allows the movable gap to define the movement direction of the limiting mechanism 50, thereby allowing the limiting mechanism 50 to more easily extend into the locking portion 31 of the locking shaft 30 after switching from the second position to the first position. Furthermore, this arrangement effectively ensures that the first locking hole 431 is aligned with the second locking hole 51 when the limiting mechanism 50 is in the first position.

[0063] In a specific embodiment of the present application, the limiting mechanism 50 is plate-shaped and has an operating paddle. Moreover, the operating paddle can be more easily operated to switch the limiting mechanism 50 between the first position and the second position.

[0064] The present application also includes one or more supporting connectors 20 for supporting the electrical equipment and the isolation panel 10. This arrangement not only provides support for the isolation panel 10 but also secures it, ensuring the isolation panel 10's protective effect on the equipment being isolated. Furthermore, this arrangement prevents the distance between the isolation panel 10 and the equipment being isolated from being too close, thereby preventing the isolation panel 10 from squeezing the equipment.

[0065] Preferably, at least one supporting connector 20 is provided at at least one corner of the isolation panel 10 , and the supporting connector 20 can be adsorbed and fixed on the electrical equipment.

[0066] Optionally, the supporting connector 20 is a magnetic connector, or the supporting connector 20 is provided with a magnetic connector.

[0067] In one embodiment of the present application, the support connector 20 includes a height adjustment portion that adjusts the distance between the isolation panel 10 and the electrical equipment to match the height of the equipment to be isolated. This arrangement allows the support connector 20 to be adjusted to suit the height of the equipment to be isolated when using the isolation and locking device to protect the equipment to be isolated, thereby ensuring that the isolation panel 10 can effectively isolate and protect the equipment to be isolated.

[0068] Preferably, the supporting connector 20 includes at least two connecting segments connected to each other, and the connection positions of two adjacent connecting segments are adjusted by fasteners to achieve height adjustment of the supporting connector 20 .

[0069] Preferably, at least one connecting segment has a sliding elongated hole, the fastener passes through another connecting segment, and the sliding elongated hole connects the two adjacent connecting segments.

[0070] Specifically, the isolation panel 10 includes at least a front panel and a side wall panel located on at least one side of the front panel, and the locking shaft 30 is connected to the side wall panel.

[0071] In a specific embodiment of the present application, the side wall plate has multiple through holes, and the portion where the locking shaft is connected to the isolation panel 10 is provided with multiple threaded holes corresponding to the through holes, and the isolation panel 10 and the locking shaft are fixed by the cooperation of screws, threaded holes and through holes.

[0072] In a specific embodiment of the present application, the side wall plate is provided with a fixed adjustment portion, which is adjustably connected to the locking shaft 30 and is used to adjust the distance between the front panel and the power equipment to adapt to the height of the equipment to be isolated.

[0073] In a specific embodiment of the present application, the fixed adjustment portion is a plurality of rows of fixed mounting holes 11 spaced apart in a direction perpendicular to the front panel, and the locking shaft 30 is provided with fixed mounting parts corresponding to the fixed mounting holes.

[0074] Specifically, the isolation panel 10 is made of a transparent material, so that operators can observe the status of the isolation equipment through the isolation panel 10.

[0075] In a specific embodiment of the present application, the locking seat 40 is fixedly mounted on the power equipment by means of magnetism, gluing or suction cup. Magnetic, gluing or suction cup installation is simple to operate, especially the magnetic and suction cup installation methods.

[0076] In a specific embodiment of the present application, the power equipment includes a switch cabinet and a protection and automation cabinet, and the device to be isolated is an electrical operating mechanism on the switch cabinet or the protection and automation cabinet that can be shielded and protected by the isolation panel 10.

[0077] Specifically, the electrical operating mechanism includes one or more of a display operating mechanism, a switching switch, an operating button and an operating hole of the protection device or the measurement and control device, wherein the display operating mechanism of the protection device or the measurement and control device includes a display operating button and / or a touch operating screen.

[0078] Specifically, the isolation panel 10 can shield and protect two or more types or more than two electrical operating mechanisms at the same time.

[0079] From the description of the above specific embodiments, it can be seen that the above embodiments of the isolation and locking device of the present invention achieve the following technical effects:

[0080] 1. On the switch cabinet or protection and automation cabinet, a locking seat is set to meet the isolation and locking requirements of the equipment to be isolated on the panel cabinet. The flag-type mechanism design enables the isolation panel to be reused multiple times in multiple locations.

[0081] 2. On the switch cabinet or protection and automation cabinet, the distance between the isolation panel and the switch cabinet or protection and automation cabinet can be adjusted according to the height of the equipment to be isolated on site. It is suitable for different types of equipment to be isolated, and the isolation locking device has a wider range of applicability.

[0082] 3. The adjustable support connector can be adsorbed on the switch cabinet or protection and automation cabinet to increase the fixed adhesion of the isolation locking device, reduce the force of the isolation panel and the locking shaft on the locking seat, and make the isolation locking device locked and fixed on the switch cabinet or protection and automation cabinet more stable.

[0083] 4. When the electrical equipment does not need to be isolated and locked, remove the isolation panel from the locking seat and fix the locking seat in a position that does not affect the operation of the power equipment. The isolation and locking device will not interfere with the normal operation of the equipment.
