[0001] The present invention relates to the technical field of circuit breakers, and in particular to a safe and leakage-proof intelligent circuit breaker. Background Art

[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time. A circuit breaker is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a release, a casing, etc.

[0003] After searching, for example, the patent number CN115346838A discloses an intelligent circuit breaker, including: a circuit breaker body; and an intelligent control mechanism, which is detachably mounted on the circuit breaker body; wherein the circuit breaker body is provided with a handle and a reset button, the handle is used to control the state of the circuit breaker body, and the reset button is used to control whether the internal structure of the circuit breaker body is reset; the intelligent control mechanism includes: a fixed shell, the interior of which forms a placement cavity with an open bottom; an automatic control module, which is movably arranged in the placement cavity through a fixed bracket; a manual control module, which is arranged on the automatic control module; a reset module, which is movably arranged at the side end of the automatic control module. According to the present invention, it does not require manual direct contact operation of the circuit breaker, and can effectively protect the staff. At the same time, the present invention has a reasonable layout, a compact structure, and a small footprint, and has a broad market application value.

[0004] However, the circuit breaker in the above patent still has the following shortcomings: During the long-term use of the circuit breaker, as the circuit breaker is tripped many times, the circuit breaker needs to be maintained and repaired after a certain number of trips to maintain the functional effect of the circuit breaker. However, the current circuit breaker lacks the necessary tripping number reminder structure. Therefore, some users cannot accurately determine the number of trips of the circuit breaker during use. This leads to the phenomenon that the users cannot perform maintenance and repair on the circuit breaker in time, which increases the safety hazards during the use of the circuit breaker. Summary of the invention

[0005] In view of this, the present invention provides a safe and leakage-proof intelligent circuit breaker, which solves the problem that the current circuit breaker lacks the necessary tripping times reminder structure. Therefore, some users cannot accurately determine the tripping times of the circuit breaker during use, which leads to the phenomenon that the users cannot perform maintenance and repair on the circuit breaker in time, increasing the potential safety hazard during the use of the circuit breaker.

[0006] The present invention provides a safe and anti-leakage intelligent circuit breaker, which specifically includes: a body; a through-type circular through-slot structure is provided on the right side of the body; a switch handle is rotatably provided on the front side of the body; a cylindrical slide bar is slidably provided in the circular through-slot on the right side of the body, the left end of the first slide bar adopts a sharp structure, and a spring is sleeved on the outer side of the slide bar. When the switch handle is turned on, it contacts the left end of the slide bar; a first rack is fixedly provided on one side of the top of the slide bar; when a short circuit occurs, the switch handle is disconnected and rotated upward, and when the switch handle rotates, it loses the blocking effect on the slide bar, and the slide bar slides to the left along the circular through-slot on the front side of the body under the action of the outer spring, contacts the mark plate on the left, and inserts the hole in the mark plate through the sharp end, thereby leaving a mark on the mark plate, so that a mark can be left on the mark plate during each short circuit process.

[0007] Furthermore, a top plate of a rectangular plate structure is fixedly provided on the top of the main body, and a group of through-type circular through-groove structures are opened on both sides of the top of the top plate; a group of limiting rods of a cylindrical structure are slidably provided in the circular through-grooves on both sides of the top plate, and the two groups of limiting rods are fixedly connected; a group of connecting rods of a Z-shaped structure are fixedly connected to one side of the limiting rod; a group of first gears are rotatably provided at the upper left corner of the front wall of the main body, and the first gear is meshed and connected with the first rack.

[0008] Furthermore, an inner ratchet is fixedly connected to the front side of the first gear; and a second gear is rotatably arranged on the front side of the upper left corner of the body.

[0009] Furthermore, an outer ratchet is fixedly connected to the rear side of the second gear, the outer ratchet has a circular ring structure, and is engaged with the inner ratchet through ratchet teeth; a fixed rod with an L-shaped rod structure is fixed to the left end of the front side of the main body; a second rack is slidably provided on the outer side of the fixed rod, and the second rack is meshed with the second gear.

[0010] Furthermore, the front bottom of the second rack is fixedly connected with a mounting groove of a rectangular plate structure, the front side of the mounting groove is provided with a rectangular groove structure, and one side of the mounting groove is provided with a through-type screw hole structure; a connecting plate with a rectangular plate structure is fixedly connected in the rectangular groove on the front side of the mounting groove, and one side of the connecting plate is provided with a through-type screw hole structure; a bolt is rotatably provided in the screw hole on one side of the mounting groove through threaded cooperation; a marking plate with a rectangular plate structure is fixedly connected to the front side of the connecting plate, and the marking plate is made of cardboard material, and the position of the marking plate corresponds to the position of the sliding rod; when replacing the marking plate, after removing the bolts, the marking plate and the connecting plate can be taken out from the mounting groove for replacement. Beneficial Effects

[0011] In the present invention, when a short circuit occurs, the switch handle is disconnected and rotated upward. When the switch handle rotates, it loses its blocking effect on the sliding rod, leaving a mark on the marking plate, so that a mark can be left on the marking plate during each short circuit. At the same time, it can be ensured that the area touched by the sliding rod is different each time, thereby avoiding the marking plate from being recorded repeatedly, resulting in inaccurate number of records. The number of times the switch handle trips is recorded by the mark on the marking plate, and the number of times the body trips can be accurately known by observing the number of marks, so that the time for maintenance of the body can be determined according to the number of trips, thereby avoiding a long period of lack of maintenance of the body due to lack of records, affecting the normal operation of the body, and causing certain safety hazards. It is more convenient for users to perform maintenance and repairs.

[0012] In addition, when the main body trips too many times and a certain number of times are recorded on the marker plate, the connecting rod will be pressed to limit the position, making it unable to move upward. At the same time, the two sets of limit rods cannot slide upward to reset, and the switch handle is limited, making it impossible to close the switch and continue to use it. This can further force the user and the unit to perform maintenance and repair on the main body, avoiding the situation where the user directly resets and uses it without observing the recorded number of times, and forcing the user to replace and reset the marker plate. At the same time, it is forced to remind the user to perform maintenance and repair on the main body before it can continue to be reset and used, further improving the standardization of the use of the main body and helping to reduce safety hazards.

[0020] Example 1: Please refer to Figures 1 to 8 : The present invention proposes a safe and anti-leakage intelligent circuit breaker, comprising: a body 1; a through circular through slot structure is provided on the right side of the body 1; a switch handle 101 is rotatably provided on the front side of the body 1; a cylindrical slide bar 105 is slidably provided in the circular through slot on the right side of the body 1, the left end of the first slide bar 105 adopts a sharp structure, and a spring is sleeved on the outer side of the slide bar 105. When the switch handle 101 is turned on, it contacts the left end of the slide bar 105; a first rack 106 is fixedly provided on one side of the top of the slide bar 105.

[0021] An inner ratchet 108 is fixedly connected to the front side of the first gear 107 ; and a second gear 109 is rotatably arranged on the front side of the upper left corner of the body 1 .

[0022] Among them, an outer ratchet 110 is fixedly connected to the rear side of the second gear 109, the outer ratchet 110 adopts a circular ring structure, and the outer ratchet 110 is engaged with the inner ratchet 108 through ratchet teeth; a fixed rod 111 with an L-shaped rod structure is fixedly provided at the left end of the front side of the main body 1; a second rack 112 is slidably provided on the outer side of the fixed rod 111, and the second rack 112 is meshed and connected with the second gear 109.

[0023] Among them, a mounting groove 113 of a rectangular plate structure is fixedly connected to the bottom of the front side of the second rack 112, a rectangular groove structure is opened on the front side of the mounting groove 113, and a through-type screw hole structure is opened on one side of the mounting groove 113; a connecting plate 114 of a rectangular plate structure is fixedly connected in the rectangular groove on the front side of the mounting groove 113, and a through-type screw hole structure is opened on one side of the connecting plate 114; a bolt 115 is rotatably arranged in the screw hole on one side of the mounting groove 113 through threaded cooperation; a marking plate 116 of a rectangular plate structure is fixedly connected to the front side of the connecting plate 114, and the marking plate 116 is made of cardboard material, and the position of the marking plate 116 corresponds to the position of the sliding rod 105.

[0024] Specific usage and function of this embodiment: In the present invention, when in use, after the body 1 is installed in the use area, if a short circuit occurs, the switch handle 101 is disconnected and rotated upward. When the switch handle 101 rotates, it loses the blocking effect on the slide bar 105. Under the action of the outer spring, the slide bar 105 slides to the left along the circular through groove on the front side of the body 1, contacts the marking plate 116 on the left, and inserts the hole of the marking plate 116 through the sharp end, thereby leaving an imprint on the marking plate 116, so that the marking plate 116 is Each time a short circuit occurs, a mark is left. When the slide bar 105 slides, the top first rack 106 is synchronously driven to slide to the left, thereby driving the first gear 107 to rotate through the first rack 106, and the first gear 107 drives the inner ratchet 108 to rotate. In this process, the outer ratchet 110 can be synchronously driven to rotate through the ratchet teeth on the outer side of the inner ratchet 108 and the engagement of the outer ratchet 110, and the second gear 109 can be driven to rotate through the outer ratchet 110. During the rotation of the second gear 109, the second rack 112 is driven along the fixed The rod 111 slides downward and simultaneously drives the mounting slot 113 to slide downward. In this process, the connecting plate 114 and the marking plate 116 installed on the front side of the mounting slot 113 are driven to slide downward synchronously for a certain distance, thereby ensuring that the area touched by the slide rod 105 is different each time, avoiding the phenomenon that the marking plate 116 is repeatedly recorded, resulting in inaccurate number of times recorded. The number of times the switch handle 101 trips is recorded through the marks on the marking plate 116. The number of times the body 1 trips can be accurately known by observing the number of marks, so that the decision can be made based on the number of trips. The time for maintenance and repair of the main body 1 can be determined to avoid long-term lack of maintenance and repair of the main body 1 due to lack of records, which will affect the normal operation of the main body 1 and cause certain safety hazards; when resetting the switch handle 101, the slide bar 105 can be reset first. During this process, since the ratchet teeth on the outside of the inner ratchet 108 cannot engage with the outer ratchet 110, the first gear 107 cannot drive the second gear 109 to rotate, and it is also impossible to drive the marking plate 116 to move, so that the marking plate 116 can remain in the adjusted position.

[0025] Example 2: Based on Example 1, please refer to Figures 1 to 8 : Among them, a top plate 102 of a rectangular plate structure is fixedly set on the top of the main body 1, and a group of through-type circular through groove structures are opened on both sides of the top of the top plate 102; a group of cylindrical limit rods 103 are slidably set in the circular through grooves on both sides of the top plate 102, and the two groups of limit rods 103 are fixedly connected; a group of Z-shaped connecting rods 104 are fixedly connected to one side of the limit rod 103; a group of first gears 107 are rotatably set at the upper left corner of the front wall of the main body 1, and the first gear 107 is meshed and connected with the first rack 106.

[0026] Specific usage and function of this embodiment: when the main body 1 trips too many times and a certain number of times are recorded on the marking plate 116, that is, when the tripping reaches a certain number of times, the second rack 112 and the mounting groove 113 will slide to the bottom of the fixed rod 111, thereby pressing and limiting the connecting rod 104, so that the connecting rod 104 cannot move upward, and at the same time, the two sets of limit rods 103 cannot slide upward and reset, and the switch handle 101 is limited, so that the switch handle 101 cannot be closed and continued to be used, thereby further forcing the user and the unit to perform maintenance and repair on the main body 1, avoiding the situation where the user directly resets and uses it without observing the recorded number of times, and forcing the user to replace and reset the marking plate 116, and at the same time forcing the user to perform maintenance and repair on the main body 1 before continuing to reset and use it, further improving the standardization of the use of the main body 1, which is conducive to reducing safety hazards; when replacing the marking plate 116, after removing the bolts 115, the marking plate 116 and the connecting plate 114 can be taken out from the mounting groove 113 for replacement.
