Description

Technical Field

[0001] This application relates to the technical field of circuit breakers, and in particular to a direct-acting circuit breaker with anti-accidental contact capability. Background Technology

[0002] An automatic circuit breaker is a type of circuit breaker in which the operating mechanism and the contact system are directly connected by a linear transmission method. Circuit breakers are typically used to control the opening and closing of circuits and are commonly used in power systems, new energy fields, industrial control and other scenarios.

[0003] The related circuit breaker includes a housing, an operating lever rotatably connected to the housing, and a control structure on the housing. The operating lever is connected to the control structure. When the operating lever is rotated, the control structure can control the opening and closing of the circuit.

[0004] When workers are repairing circuit breakers, they may accidentally touch the operating lever, causing the lever to connect the circuit through the control structure, which could lead to a dangerous situation for the workers. Summary of the Invention

[0005] To address the issue of workers potentially accidentally touching the operating lever during maintenance, this application provides a direct-acting circuit breaker designed to prevent accidental contact.

[0006] This application provides a direct-acting circuit breaker with anti-accidental contact feature, which adopts the following technical solution:

[0007] A direct-acting circuit breaker with anti-accidental contact capability includes a housing, an operating rod rotatably connected to the housing, a control structure on the housing, the operating rod rotatably connected to the control structure, a stop plate slidably connected to the housing, a stop block on the stop plate, and a stop groove on the operating rod for the stop block to be inserted into; when the stop block is inserted into the stop groove, the operating rod is fixed to the housing.

[0008] By adopting the above technical solution, the stop block is inserted into the stop groove to limit the operation rod, so that the operation rod cannot rotate on the housing. This allows the operator to fix the operation rod by sliding the stop plate during maintenance, thus preventing the operator from accidentally touching the operation rod.

[0009] Optionally, two waterproof strips are slidably connected to the housing, and waterproof sponges are provided on the waterproof strips. The waterproof strips are located on both sides of the operating rod. When the two waterproof strips abut against each other, the waterproof sponges abut against the operating rod.

[0010] By adopting the above technical solution, two waterproof strips are respectively set on both sides of the operating rod, so that the two waterproof strips can abut against the operating rod, and the water on the outer surface of the operating rod can be absorbed by the waterproof sponge. This prevents the water on the outer surface of the operating rod from spreading into the control structure, reducing the possibility of the control structure being damaged due to excessive moisture.

[0011] Optionally, the stop plate is provided with a first rack, and the waterproof strip is provided with a second rack, and a rotating gear is meshed between the first rack and the second rack; when the stop block is inserted into the stop groove, the waterproof sponge does not abut against the operating rod; when the waterproof sponge abuts against the operating rod, the stop block disengages from the stop groove.

[0012] By adopting the above technical solution, when the worker slides the stop plate and the stop block disengages from the stop groove, the first rack drives the second rack to move through the rotating gear, allowing the waterproof sponge to abut against the operating rod. This enables the waterproof sponge to absorb water from the outer surface of the operating rod, eliminating the need for the worker to move the waterproof strip again and reducing the number of steps required for the worker's operation.

[0013] Optionally, the housing has a receiving cavity, and the waterproof strip and the stop plate are slidably connected in the receiving cavity. The housing has a through hole communicating with the receiving cavity, and a movable strip is slidably connected in the through hole. The waterproof sponge has a receiving block for inserting into the through hole. When the receiving block is located in the through hole, the waterproof sponge does not abut against the operating rod, and at this time the movable strip protrudes from the housing.

[0014] By adopting the above technical solution, when the waterproof strip slides, the waterproof sponge can move to the perforation, allowing the receiving block to move from the receiving cavity to the perforation. The receiving block pushes the moving strip, causing the moving strip to protrude from the classroom, so that the staff can directly observe the position of the moving strip. This allows the staff to directly judge whether the waterproof sponge is in contact with the operating rod, and avoids the staff forgetting to move the waterproof strip, causing water from the outside of the operating rod to enter the control structure.

[0015] Optionally, the housing has a movable groove with a through hole, the movable groove allows the movable strip to slide, the waterproof sponge is slidably connected to the waterproof strip, and the waterproof sponge can be detached from the through hole; when the movable strip is in the movable groove, the movable strip is not in the movement path of the waterproof sponge.

[0016] By adopting the above technical solution, since the waterproof sponge can detach from the perforation, when the receiving block is located in the perforation, the receiving block can pre-fix the waterproof sponge. At this time, the worker moves the moving strip from the perforation to the moving groove, so that the moving strip is not on the moving path of the waterproof sponge detaching from the receiving cavity, thereby allowing the worker to take the waterproof sponge out of the receiving cavity, so as to facilitate the worker to replace the waterproof sponge.

[0017] Optionally, the waterproof sponge is provided with a fixing block, and the waterproof strip is provided with a fixing hole for the fixing block to be inserted. A fixing strip is slidably connected in the fixing hole, and a linkage strip is slidably connected on the housing. The linkage strip is located on the moving path of the fixing strip. When the fixing block is inserted into the fixing hole, the fixing strip protrudes and is located on the moving path of the linkage strip. When the linkage strip is inserted into the receiving cavity, the fixing block disengages from the fixing hole.

[0018] By adopting the above technical solution, the fixing block is inserted into the fixing hole to fix the waterproof strip and the waterproof sponge together, preventing the separation of the waterproof sponge and the waterproof strip. The fixing block pushes the fixing strip to slide in the fixing hole, so that the fixing strip is located on the moving path of the linkage bar, so that the staff can move the fixing strip by the linkage bar. When the staff slides the linkage bar, the linkage bar can push the fixing strip to move, so that the fixing strip can move the fixing block, so that the fixing block can be disengaged from the fixing hole, thereby separating the waterproof sponge and the waterproof strip, so as to facilitate the replacement of the waterproof strip.

[0019] Optionally, the waterproof strip has a dovetail groove, and the waterproof sponge has a dovetail block; when the dovetail block is located in the dovetail groove, the waterproof sponge is fixed to the waterproof strip.

[0020] By adopting the above technical solution, the connection strength between the waterproof sponge and the waterproof strip is increased by placing the dovetail block inside the dovetail groove, thereby further strengthening the reliability between the waterproof sponge and the waterproof strip.

[0021] Optionally, the housing is provided with a waterproof spring, and the waterproof spring is provided with a push block. The waterproof spring drives the waterproof sponge to abut against the operating rod through the push block.

[0022] By adopting the above technical solution, the push block is moved by the waterproof spring, allowing the push block to abut against the waterproof sponge, and the waterproof sponge to abut against the outer surface of the operating rod. When the operating rod rotates, there will be a certain amount of friction between the operating rod and the waterproof sponge, causing the waterproof sponge to be worn by the operating rod. Due to the drive of the waterproof spring, the waterproof sponge and the operating rod are less likely to have gaps due to wear, further increasing the waterproof performance of the operating rod.

[0023] Optionally, the push block has a push ramp, and the distance between the push ramp and the perforation gradually increases along the direction from the waterproof strip to another waterproof sleeve; when the waterproof sponge passes through the perforation, the push ramp is located on the movement path of the waterproof sponge.

[0024] By adopting the above technical solution, when the waterproof sponge is installed at the perforation, the waterproof sponge can push the inclined plane to move the pushing block in the direction of the pushing spring, so that the pushing block is located on the side of the waterproof sponge facing the waterproof strip, thereby allowing the waterproof spring to drive the waterproof sponge to move through the pushing block.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By inserting a stop block into the stop groove, the stop block limits the operation rod, preventing it from rotating on the housing. This allows the operator to slide the stop plate to fix the operation rod during maintenance, preventing accidental operation.

[0027] 2. When the operator slides the stop plate to disengage the stop block from the stop groove, the first rack drives the second rack to move, allowing the waterproof sponge to abut against the operating rod. This enables the waterproof sponge to absorb water from the outer surface of the operating rod, eliminating the need for the operator to move the waterproof strip again and reducing the operator's steps.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This embodiment discloses a direct-acting circuit breaker with anti-accidental contact feature. (Refer to...) Figure 1 A direct-acting circuit breaker with anti-accidental contact capability includes a housing 1, an operating lever 11 rotatably connected to the housing 1, and a control structure 12 fixedly connected to the housing 1. The rotation of the operating lever 11 can realize the opening and closing of the circuit through the control structure 12.

[0036] Reference Figure 1 and Figure 2 The housing 1 has a receiving cavity 2, and two waterproof blocks 212 are slidably connected in the receiving cavity 2. The two waterproof blocks 212 are located on the upper and lower sides of the operating rod 11, respectively.

[0037] Reference Figure 2 and Figure 3 A waterproof strip 21 is fixedly connected to the waterproof block 212. The waterproof strip 21 is arc-shaped, and two waterproof strips 21 are located on the upper and lower sides of the operating rod 11, respectively. A dovetail groove 211 is formed on the end face of the waterproof strip 21 facing the other waterproof strip 21, and the dovetail groove 211 extends along the width of the waterproof strip 21 to the side of the waterproof strip 21. A waterproof sponge 22 is detachably connected to the waterproof strip 21, and the waterproof sponge 22 can absorb moisture from the operating rod 11. A dovetail block 221 is fixedly connected to the waterproof sponge 22, and the dovetail block 221 can slide within the dovetail groove 211. When the dovetail block 221 is located within the dovetail groove 211, the waterproof sponge 22 can be fixed to the waterproof strip 21.

[0038] Reference Figure 2 and Figure 3 The housing 1 has a sliding hole 23 that connects to the receiving cavity 2, and the sliding hole 23 extends vertically. A sliding block 231 is fixedly connected to the waterproof block 212, and the sliding block 231 extends out of the housing 1 through the sliding hole 23. The operator can move the waterproof strip 21 by sliding the sliding block 231.

[0039] Reference Figure 2 and Figure 4 A receiving groove 24 is formed on the end face of the waterproof strip 21 facing another waterproof strip 21, and the receiving groove 24 extends along the length direction of the waterproof strip 21. Multiple waterproof springs 241 are fixedly connected to the bottom wall of the receiving groove 24, and the multiple waterproof springs 241 are arranged in an array along the length direction of the receiving groove 24. A pushing block 242 is fixedly connected to the surface of the waterproof spring 241 away from the bottom wall of the receiving groove 24, and the waterproof spring 241 drives the pushing block 242 to protrude out of the receiving groove 24.

[0040] Reference Figure 2The housing 1 has two through holes 25 that connect to the receiving cavity 2. A movable strip 251 is slidably connected inside the through hole 25, and the movable strip 251 can be completely located inside the through hole 25. A receiving block 222 is fixedly connected to the surface of the waterproof sponge 22. The receiving block 222 is elastic and can be inserted into the through hole 25.

[0041] Reference Figure 2 The housing 1 has a movable groove 252 that connects to the through hole 25. The movable groove 252 allows the movable strip 251 to slide, and the movable groove 252 extends vertically. The movable strip 251 can move from the through hole 25 into the movable groove 252, ensuring that the movable strip 251 is not in the path of the waterproof sponge 22 leaving the receiving cavity 2. At this time, the operator can remove the waterproof sponge 22 from the through hole 25, thus separating the waterproof sponge 22 from the waterproof strip 21.

[0042] Reference Figure 2 and Figure 4 A pushing ramp 243 is formed on the surface of the pushing block 242 facing the perforation 25. The distance between the pushing ramp 243 and the perforation 25 gradually increases along the direction from one waterproof strip 21 to another, and the pushing ramp 243 is located in the insertion path of the waterproof sponge 22. When the waterproof sponge 22 is inserted into the receiving cavity 2 through the perforation 25, the waterproof sponge 22 drives the pushing block 242 to move through the pushing ramp 243, allowing the pushing block 242 to move into the receiving groove 24, so that the pushing block 242 is located on the side of the waterproof sponge 22 facing the waterproof spring 241.

[0043] Reference Figure 2 , Figure 4 and Figure 5 A fixing block 26 is integrally formed on the surface of the waterproof sponge 22, and a fixing hole 261 for inserting the fixing block 26 is formed on the surface of the waterproof strip 21. A fixing strip 262 is slidably connected in the fixing hole 261 and can be inserted into the fixing hole 261. When the fixing strip 262 is in the fixing hole 261, the fixing block 26 can be disengaged from the fixing hole 261, and the waterproof sponge 22 and the waterproof strip 21 can be separated.

[0044] Reference Figure 5 The housing 1 has a linkage hole 263 that connects to the receiving cavity 2. A linkage bar 264 is slidably connected in the linkage hole 263 and can be inserted into the receiving cavity 2. A fixing slope 265 is formed on the surface of the fixing bar 262 facing the linkage hole 263. The distance between the fixing slope 265 and the linkage hole 263 gradually decreases along the direction from one waterproof strip 21 to another, and the fixing slope 265 is located on the moving path of the linkage bar 264.

[0045] Reference Figure 5When the operator slides the linkage bar 264, inserting it into the receiving cavity 2, the linkage bar 264 drives the fixing bar 262 to move through the fixing inclined surface 265, causing the fixing bar 262 to move into the fixing hole 261. At this time, the fixing bar 262 drives the fixing block 26 to move, separating the waterproof sponge 22 from the waterproof strip 21. At this time, the receiving block 222 is located at the perforation 25, and the operator can pull the receiving block 222 to remove the waterproof sponge 22 from the receiving cavity 2, thus replacing the waterproof sponge 22.

[0046] Reference Figure 2 A stop plate 3 is slidably connected inside the receiving cavity 2, and the stop plate 3 slides vertically. A stop block 31 is fixedly connected to the surface of the stop plate 3, and a stop groove 32 for the stop block 31 to be inserted is opened on the outer surface of the operating rod 11. When the stop block 31 is located in the stop groove 32, the operating rod 11 is fixed, and it is difficult for the operator to rotate the operating rod 11.

[0047] Reference Figure 2 A first rack 33 is fixedly connected to the surface of the stop plate 3, and a second rack 34 is fixedly connected to the surface of the waterproof strip 21. A rotating gear 35 meshes between the first rack 33 and the second rack 34. When the waterproof strip 21 slides downward until the waterproof sponge 22 abuts the operating lever 11, the second rack 34 drives the stop plate 3 to slide upward through the rotating gear 35 and the first rack 33, and the stop block 31 disengages from the stop groove 32.

[0048] The implementation principle of a direct-acting circuit breaker with anti-accidental contact in this application embodiment is as follows: the operator moves the waterproof strip 21 by sliding block 231. At this time, the waterproof strip 21 moves the first rack 33 by the second rack 34 and rotating gear 35, so that the stop block 31 is located in the stop groove 32, and the stop plate 3 limits the operation rod 11.
