Description

Technical Field

[0001] This disclosure relates to the field of electrical equipment technology, and more specifically, to an anti-electric shock device and electrical equipment. Background Technology

[0002] In low-voltage power distribution systems, meter boxes are usually equipped with overvoltage and overcurrent protection devices such as circuit breakers or fuses, or manual power-off devices such as knife switches. However, when replacing or repairing electrical equipment, it is usually necessary to open the meter box to disconnect the internal wiring or remove the fuse to cut off the power before operating the meter box. Accidentally touching live parts can also cause electric shock, posing a significant safety hazard.

[0003] In related technologies, management measures such as the "two-ticket three-system" and setting conspicuous signs in the incomplete power outage switch intervals are adopted to ensure personal safety. However, there are still cases where maintenance personnel accidentally enter the energized intervals during maintenance, resulting in electric shock accidents due to accidentally entering the incomplete power outage intervals. Utility Model Content

[0004] The purpose of this disclosure is to provide an electric shock protection device and electrical equipment that can reduce the possibility of accidental electric shock to maintenance personnel and ensure their safety, thereby at least partially solving the aforementioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this disclosure, an electric shock protection device is provided for a circuit breaker, the electric shock protection device comprising:

[0006] The housing has an interior space for mounting the circuit breaker.

[0007] A conductive element for electrical connection to the circuit breaker;

[0008] A door body, connected to the housing, has an open position and a closed position. In the open position, the door body is used to avoid the circuit breaker and disconnect the conductive element and the circuit breaker. In the closed position, the door body is used to shield the circuit breaker and allow the conductive element and the circuit breaker to pass through.

[0009] A drive mechanism is connected to the door body so that the door body can switch between the open position and the closed position.

[0010] Optionally, the conductive element includes a conductive post electrically connected to the circuit breaker, a disconnecting post electrically connected to the conductive post in an on / off manner, and an elastic element driving the disconnecting post. In the closed position, the door can stop the disconnecting post from moving away from the conductive post, and in the open position, the door can avoid the disconnecting post from moving away from the conductive post.

[0011] Optionally, the anti-electric shock device further includes a mounting block disposed in the installation space, the mounting block having an installation groove formed inside, at least a portion of the power-off post being slidably connected to the installation groove, at least a portion of the conductive post being placed in the installation groove, and the elastic element being connected between the power-off post and the groove wall of the installation groove.

[0012] Optionally, the drive mechanism includes a movable pusher and a drive member connected to the pusher. The pusher is disposed within the installation space and is used to drive the door to switch from the closed position to the open position. The drive member is at least partially located outside the installation space.

[0013] Optionally, the driving mechanism further includes a base block, and the pushing member includes a pushing block slidably connected to the base block. The driving member drives the pushing block to slide toward the door body to switch the door body from the closed position to the open position.

[0014] Optionally, the pushing block includes a first block for pushing the door body to move, a second block arranged parallel to the first block, and a third block connecting the first block and the second block. The third block is provided with a first limiting post and a second limiting post. The base block is formed with a first sliding groove for the first limiting post and the second limiting post to slide, and a second sliding groove for the second limiting post to slide. The second sliding groove is constructed as an arc-shaped groove communicating with the first sliding groove. The distance between the opposite two side walls of the second sliding groove at the end away from the first sliding groove is less than the radial dimension of the second limiting post.

[0015] Optionally, the drive mechanism further includes a linkage assembly, which includes a first linkage and a second linkage rotatably connected to each other. The first linkage is rotatably connected to the push block. The drive component includes a rotating shaft rotatably connected to the base block. The second linkage is fixedly sleeved on the rotating shaft. The end of the rotating shaft away from the second linkage passes through the housing and is fitted with a handwheel. The handwheel is located outside the housing.

[0016] Optionally, the number of the drive mechanisms is set to two, the two drive mechanisms are arranged opposite to each other, the door body is arranged between the two drive mechanisms, and a linkage is provided between the two drive mechanisms.

[0017] Optionally, the anti-electric shock device further includes a locking assembly, which includes a locking block slidably connected to the housing and a locking hole formed in the door body. In the closed position, the locking block is inserted into the locking hole to limit the movement of the door body away from the housing.

[0018] According to a second aspect of this disclosure, an electrical device is provided, including a circuit breaker and an electric shock protection device as described above.

[0019] The above technical solution places the circuit breaker within the internal installation space of the anti-electric shock device housing. When multiple power supply intervals require maintenance, power to a single circuit breaker can be disconnected by opening the door. Simultaneously, the open door serves as a warning, reducing the possibility of maintenance personnel accidentally touching a live circuit breaker and suffering electric shock, thus improving the safety of maintenance personnel. Specifically, when multiple power supply intervals require maintenance, the door of the corresponding circuit breaker is opened via a drive mechanism. When the door is in the open position, it disconnects the conductive components and the circuit breaker, ensuring the safety of maintenance personnel. Simultaneously, the drive mechanism reduces the possibility of maintenance personnel directly contacting the door and accidentally receiving electric shock due to the door or housing being live. When the door is in the closed position, it allows the conductive components and the circuit breaker to remain connected, ensuring the normal operation of the circuit breaker. Furthermore, the door and housing provide protection for the circuit breaker.

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the interior and exterior of the outline of the corresponding component; "far" and "near" refer to the distance of the corresponding component relative to another component in terms of spatial position. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance. When the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0031] The electric shock protection device and electrical equipment in the exemplary embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0032] According to the first aspect of this disclosure, reference to Figures 1 to 4 This disclosure provides an electric shock protection device 10 for a circuit breaker. The electric shock protection device 10 includes a housing 1, a conductive element 2, a door 3, and a drive mechanism 4.

[0033] The housing 1 has an installation space 11 inside for installing a circuit breaker;

[0034] Conductive component 2 is used for electrical connection to the circuit breaker;

[0035] The door 3 is connected to the housing 1. The door 3 has an open position and a closed position. In the open position, the door 3 is used to avoid the circuit breaker and disconnect the conductive component 2 and the circuit breaker. In the closed position, the door 3 is used to shield the circuit breaker and allow the conductive component 2 and the circuit breaker to pass through.

[0036] The drive mechanism 4 drives the door body 3 so that the door body 3 can switch between the open position and the closed position.

[0037] Through the above technical solution, the circuit breaker is installed in the internal installation space 11 of the housing 1 of the anti-electric shock device 10. When multiple power supply intervals need to be inspected, the power to a single circuit breaker can be cut off by opening the door 3. At the same time, the door 3 in the open position can serve as a warning to reduce the possibility of maintenance personnel accidentally touching a live circuit breaker and getting an electric shock, thereby improving the safety of maintenance personnel during work. Specifically, when multiple power supply intervals need to be inspected, the door 3 of the corresponding circuit breaker is opened by the drive mechanism 4. When the door 3 is in the open position, the conductive component 2 and the circuit breaker can be disconnected to ensure the safety of maintenance personnel. At the same time, opening the door 3 by the drive mechanism 4 reduces the possibility of maintenance personnel accidentally getting an electric shock due to direct contact with the door 3 or the housing 1 being live. When the door 3 is in the closed position, the conductive component 2 and the circuit breaker can be connected to the circuit, ensuring the normal operation of the circuit breaker. At the same time, the circuit breaker can be protected by the door 3 and the housing 1.

[0038] In some embodiments, reference Figure 2 and Figure 4 As shown, the conductive component 2 may include a conductive post 21 electrically connected to the circuit breaker, a disconnecting post 22 electrically connected to the conductive post 21, and an elastic component 23 driving the disconnecting post 22. In the closed position, the door 3 can prevent the disconnecting post 22 from moving away from the conductive post 21. In the open position, the door 3 can avoid the disconnecting post 22 from moving away from the conductive post 21. Thus, when multiple power supply intervals need maintenance, the drive mechanism 4 can drive the door 3 from the closed position to the open position. During this process, the elastic component 23 drives the disconnecting post 22 to move away from the conductive post 21, so that the disconnecting post 22 and the conductive post 21 are separated. At this time, the conductive post 21 is not energized, and therefore the circuit breaker is not energized. After the maintenance is completed, the maintenance personnel switch the door 3 from the open position to the closed position. During this process, the door 3 drives the disconnecting post 22 to move closer to the conductive post 21, so that the disconnecting post 22 and the conductive post 21 make contact, and the circuit breaker operates normally.

[0039] It is understood that, after maintenance is completed and circuit safety is ensured, the door 3 can be switched from the open position to the closed position by the drive mechanism 4, or maintenance personnel can switch the door 3 from the open position to the closed position by wearing insulated gloves. This disclosure does not specifically limit this. In addition, the elastic element 23 can be constructed as a spring or elastic band, etc., to provide elastic force to the power-off post 22 toward the side away from the conductive post 21. This disclosure is not limited to this.

[0040] In some embodiments, reference Figure 4As shown, the anti-electric shock device 10 may further include a mounting block 5 disposed within the mounting space 11. The mounting block 5 has a mounting groove 51 formed inside it. At least a portion of the power-off post 22 is slidably connected to the mounting groove 51, and at least a portion of the conductive post 21 is placed within the mounting groove 51. An elastic member 23 is connected between the power-off post 22 and the groove wall of the mounting groove 51. In this disclosure, the elastic member 23 is exemplary constructed as a spring, which is connected between the groove wall of the mounting groove 51 on the side away from the power-off post 22 and the power-off post 22, and provides a spring force to the power-off post 22 toward the side away from the conductive post 21.

[0041] Thus, during maintenance, the door 3 switches from the closed position to the open position to avoid the power-off post 22. The spring drives the power-off post 22 to slide away from the conductive post 21 to disconnect from the conductive post 21, thereby de-energizing the circuit breaker. After maintenance is completed, the door 3 switches from the open position to the closed position, driving the power-off post 22 to slide towards the conductive post 21 to contact it, thereby energizing the circuit breaker. It is understood that an annular connecting plate is circumferentially arranged around the outer wall of the power-off post 22. One end of the spring is connected to the annular connecting plate, and the other end is connected to the side wall of the mounting groove 51 away from the power-off post 22, facilitating the connection of the spring and the sliding of the power-off post 22 driven by the spring. Furthermore, in some other possible alternative embodiments not shown in the accompanying drawings, one end of the spring can be directly connected to the outer wall of the power-off post 22; this disclosure is not limited to this.

[0042] In some embodiments, reference Figure 2 and Figure 3 As shown, the drive mechanism 4 may include a movable pusher 41 and a drive member 42 that drives the pusher 41. The pusher 41 is disposed within the installation space 11 and is used to drive the door 3 from the closed position to the open position. The drive member 42 is at least partially located outside the installation space 11. In this way, maintenance personnel can drive the pusher 41 to open the door 3 by using the drive member 42, which is at least partially located outside the installation space 11, thereby disconnecting the power circuit breaker and ensuring the safety of the maintenance process. The power disconnection process is also more convenient.

[0043] The pusher 41 can be moved in any suitable manner; in some exemplary embodiments, reference is made to... Figure 2 and Figure 3As shown, the drive mechanism 4 may further include a base block 43, and the pusher 41 includes a push block 411 slidably connected to the base block 43. The drive member 42 drives the push block 411 to slide toward the door body 3 to switch the door body 3 from the closed position to the open position. The base block 43 may be connected to the side of the housing 1 near the hinge end of the door body 3, so that the push block 411 can push the door body 3 to rotate a large angle with a small sliding distance, thereby reducing the occupation of the installation space 11. Simultaneously, the door body 3 has a large opening, providing maintenance personnel with a large maintenance space for normal maintenance work.

[0044] It is understood that in some other possible alternative embodiments not shown in the accompanying drawings, the pusher 41 may be rotatably connected to the base block 43 so that it can push the door 3 to rotate by its own rotation so that the door 3 switches from the closed position to the open position, but this disclosure is not limited thereto.

[0045] The push block 411 can be constructed in any suitable manner. This disclosure exemplarily constructs the push block 411 as a Z-shaped block. In some embodiments, reference is made to... Figure 2 and Figure 3 As shown, the pushing block 411 may include a first block 4111 for pushing the door body 3 to move, a second block 4112 arranged parallel to the first block 4111, and a third block 4113 connecting the first block 4111 and the second block 4112. The third block 4113 is provided with a first limiting post 44 and a second limiting post 45. The base block 43 is formed with a first sliding groove 431 for sliding the first limiting post 44 and the second limiting post 45, and a second sliding groove 432 for sliding the second limiting post 45. The second sliding groove 432 is constructed as an arc-shaped groove communicating with the first sliding groove 431.

[0046] Thus, during the process of switching the door 3 from the closed position to the open position, the drive member 42 can drive the push block 411 to slide along the extension direction of the first slide groove 431 to push the door 3 to rotate. When the door 3 rotates to the open position, the drive member 42 can drive the push block 411 to continue rotating. At this time, the second limiting post 45 slides along the second slide groove 432 away from the first slide groove 431, so that the push block 411 rotates around the first limiting post 44. The distance between the opposite two side walls of the second slide groove 432 away from the first slide groove 431 is less than the radial dimension of the second limiting post 45, so as to limit the second limiting post 45. Therefore, the possibility of the second limiting post 45 sliding along the second slide groove 432 towards the first slide groove 431 can be reduced, so that the push block 411 remains in contact with the door 3 when the door 3 is in the open position, so as to stop the rotation of the door 3 towards the direction of the housing 1, so that the door 3 is kept in the open position, which is convenient for maintenance personnel to carry out maintenance work.

[0047] In some embodiments, reference Figure 2 and Figure 3 As shown, the drive mechanism 4 may also include a linkage assembly 46, which includes a first linkage 461 and a second linkage 462 rotatably connected to each other. The first linkage 461 is rotatably connected to the push block 411. The drive member 42 includes a rotating shaft 421 rotatably connected to the base block 43. The second linkage 462 is fixedly sleeved on the rotating shaft 421. The end of the rotating shaft 421 away from the second linkage 462 passes through the housing 1 and is sleeved with a handwheel 422. The handwheel 422 is located outside the housing 1. In this way, when multiple power supply intervals need to be inspected, the maintenance personnel can turn the handwheel 422. The handwheel 422 drives the rotating shaft 421 to rotate, the rotating shaft 421 drives the second connecting rod 462 to rotate, and the second connecting rod 462 drives the first connecting rod 461 to rotate. This first drives the push block 411 to slide. At this time, the first limiting post 44 and the second limiting post 45 slide in the first slide groove 431. When the door 3 is rotated to the open position, the handwheel 422 is turned again to drive the rotating shaft 421 and the second connecting rod 462 to rotate. The first connecting rod 461 drives the push block 411 to rotate. At this time, the second limiting post 45 slides along the second slide groove 432 away from the first slide groove 431, so that the push block 411 rotates around the first limiting post 44 until the second limiting post 45 moves to the end of the second slide groove 432 away from the first slide groove 431. At this time, the second slide groove 432 can limit the second limiting post 45 to keep the door 3 in the open position. After maintenance is completed, the maintenance personnel can rotate the handwheel 422 in the reverse direction. The handwheel 422 drives the rotating shaft 421 to rotate in the reverse direction, the rotating shaft 421 drives the second connecting rod 462 to rotate in the reverse direction, and the second connecting rod 462 drives the first connecting rod 461 to rotate in the reverse direction. This first drives the push block 411 to rotate in the reverse direction around the first limiting post 44. At this time, the second limiting post 45 slides along the second slide groove 432 towards the first slide groove 431 until the second limiting post 45 moves into the first slide groove 431. Then, the handwheel 422 is rotated to drive the rotating shaft 421 and the second connecting rod 462 to rotate. The first limiting post 44 and the second limiting post 45 slide in the first slide groove 431 so that the push block 411 disengages from the door body 3, and the door body 3 can rotate from the open position to the closed position.

[0048] It is understood that a spring-loaded mechanism can be provided between the door body 3 and the housing 1 to allow the door body 3 to rotate from the open position to the closed position. The spring-loaded mechanism can be constructed as a torsion spring or an automatic hydraulic hinge, etc., and this disclosure does not specifically limit it.

[0049] In some embodiments, reference Figure 2 and Figure 3As shown, the number of drive mechanisms 4 can be set to two, with the two drive mechanisms 4 arranged opposite each other. The door body 3 is located between the two drive mechanisms 4. One drive mechanism 4 can be located on one side wall of the housing 1 adjacent to the door body 3, and the other drive mechanism 4 can be located on the other side wall of the housing 1 adjacent to the door body 3. For example, the base block 43 can be connected to the inner side wall of the housing 1, and the push block 411 can be slidably connected to the side of the base block 43 away from the housing 1. In addition, a linkage rod 6 is provided between the two drive mechanisms 4. In this way, maintenance personnel can switch the door body 3 from the closed position to the open position by using the drive mechanism 4 located on the side closer to the hinge side of the door body 3. Furthermore, maintenance personnel can also switch the door body 3 from the closed position to the open position by using the drive mechanism 4 located on the side away from the hinge side of the door body 3, making the operation more convenient.

[0050] It is understood that the linkage 6 can be set in any suitable position. For example, the linkage 6 can be set between the two push blocks 411, or the linkage 6 can be set between the two first linkages 461. This disclosure does not make any specific limitation in this regard.

[0051] In some embodiments, reference Figure 1 and Figure 2 As shown, the electric shock protection device 10 may further include a locking assembly 7, which includes a locking block 71 slidably connected to the housing 1 and a locking hole 72 formed in the door body 3. In the closed position, the locking block 71 is inserted into the locking hole 72 to limit the movement of the door body 3 away from the housing 1. In this way, the door body 3 can be locked in the open position to ensure that the circuit breaker remains in the open state and is in normal working condition.

[0052] For example, a fixing block 73 is formed on the upper part of the housing 1 for sliding of the locking block 71. The locking block 71 can be constructed in an L-shape, and a protrusion 711 facing the door body 3 is formed on the top of the locking block 71. A slot 731 is formed on the fixing block 73 for the protrusion 711 to be inserted into. The protrusion 711 can slide in the slot 731 to drive the locking block 71 to slide relative to the housing 1, so as to be able to be inserted into the locking hole 72 of the door body 3 to limit the door body 3, or to disengage from the locking hole 72 of the door body 3 to release the limitation on the door body 3. A baffle 31 can be connected to the door body 3 to form the locking hole 72. In the closed position, the baffle 31 is located on the side of the housing 1 adjacent to the door body 3. In addition, a lock hole 712 can also be formed on the locking block 71 for locking to limit the sliding of the locking block 71 relative to the housing 1.

[0053] According to a second aspect of this disclosure, an electrical device is provided, including a circuit breaker and the aforementioned electric shock protection device 10, which can be applied to the operating environment of the circuit breaker and has all the beneficial effects of the aforementioned electric shock protection device 10.

[0054] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0056] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
