Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a sensor-monitored water-immersion anti-electric shock circuit breaker. Background Art

[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use.

[0003] However, it still has the following disadvantages in actual use:

[0004] The existing circuit breaker casing is usually made of plastic. When it collides with the outside world, the plastic material is relatively fragile and easily breaks, thereby damaging the electrical components inside the circuit breaker and exposing the electrical components inside the circuit breaker, posing a safety hazard and being inconvenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide a sensor-monitored water-immersion anti-electric shock circuit breaker to solve the problem mentioned in the above background technology that the existing circuit breaker casing is usually made of plastic material. When colliding with the outside world, the plastic material is relatively fragile and easily breaks, thereby damaging the electrical components inside the circuit breaker and exposing the electrical components inside the circuit breaker, posing a safety hazard and being inconvenient to use.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a sensor-monitored water-immersion anti-electric shock circuit breaker, comprising:

[0008] A circuit breaker assembly, the circuit breaker assembly comprising a housing;

[0009] A protection assembly, the protection assembly comprising a fixed plate, a telescopic spring, a slide groove, a slide shaft, a support plate and a support column;

[0010] The fixed plate is fixedly connected to the two end positions of the outer side of the shell, the telescopic spring is fixedly connected to the inner position of the fixed plate, the slide groove is opened on both sides of the fixed plate, the slide shaft is placed in the inner position of the slide groove, one end of the support plate is sleeved on the outer surface position of the slide shaft, and the support column is sleeved on the inner position of the other end of the support plate.

[0011] Furthermore, the circuit breaker assembly also includes a switch;

[0012] The switch is located inside the shell, and a leakage sensor is contained inside the shell.

[0013] Furthermore, the other end of the telescopic spring is fixedly connected to the lower end of the support plate, and the support plate is in an inclined state.

[0014] Furthermore, the support column is located at a central position outside the shell, and the sliding groove is opened relative to the sliding shaft.

[0015] Furthermore, it also includes a movable assembly, which includes a support rod, a baffle, a first fixing slot, a second fixing slot, a first electromagnetic lock, and a second electromagnetic lock;

[0016] The support rod is located on both sides of the shell, the baffle is fixedly connected to the top end of the support rod, the first fixed groove is opened at the upper end of the support rod, the second fixed groove is opened at the lower end of the support rod, the first electromagnetic lock is fixedly connected to the upper end of the outer side of the shell, and the second electromagnetic lock is fixedly connected to the lower end of the outer side of the shell.

[0017] Furthermore, the first electromagnetic lock and the second electromagnetic lock are electrically connected to the leakage sensor through a circuit, and the baffle is located outside the shell.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The utility model provides a protective component. When the outside world collides with the circuit breaker housing, the outer end of the support plate contacts the outside world and moves inward under the drive of the outside world. The inward movement of the support plate drives the sliding shaft to move outward, thereby driving the telescopic spring to be compressed. The telescopic spring is compressed to generate elastic force, thereby blocking the movement of the support plate, so that foreign objects will not come into contact with the housing, effectively protecting the housing, and increasing the safety of the circuit breaker.

[0020] 2. Based on the first beneficial effect, by setting up a movable component, when the circuit breaker is flooded, the knife switch automatically opens to avoid electric shock accidents. However, when the knife switch is open, the outside cannot judge whether the water has flooded, and it is easy to close the switch. The lock tongue of the first electromagnetic lock is controlled by the leakage sensor to retract, so that the support rod moves downward and drives the baffle to move downward. At the same time, the lock tongue of the second electromagnetic lock extends outward, so that the second electromagnetic lock fixes the support rod, so that the baffle closes the front end of the shell to avoid operation on the knife switch.

[0032] See also Figure 1-3 As shown, this embodiment is a sensor-monitored water-immersion anti-electric shock circuit breaker, comprising:

[0033] A circuit breaker assembly, the circuit breaker assembly comprising a housing 11;

[0034] A protection assembly, the protection assembly includes a fixing plate 21, a telescopic spring 22, a slide groove 23, a slide shaft 24, a support plate 25 and a support column 26;

[0035] The fixing plate 21 is fixedly connected to both ends of the outer side of the housing 11, the telescopic spring 22 is fixedly connected to the inner side of the fixing plate 21, the slide slot 23 is opened at both sides of the fixing plate 21, the slide shaft 24 is placed inside the slide slot 23, one end of the support plate 25 is sleeved on the outer surface of the slide shaft 24, and the support column 26 is sleeved on the inner side of the other end of the support plate 25;

[0036] The fixed plate 21 is used to support the telescopic spring 22, the telescopic spring 22 is used to limit the support plate 25, the slide groove 23 is used to place the slide shaft 24, the slide shaft 24 is used to drive the support plate 25 to move, the support plate 25 is used to support the support column 26 and contact with the outside world, and the support column 26 is used to connect the two groups of support plates 25;

[0037] The circuit breaker assembly also includes a switch 12;

[0038] The switch 12 is located inside the housing 11, and the housing 11 contains a leakage sensor;

[0039] The switch 12 is used to open and close the circuit breaker assembly;

[0040] The other end of the telescopic spring 22 is fixedly connected to the lower end of the support plate 25, and the support plate 25 is in an inclined state;

[0041] When the support plate 25 tilts and rotates inward, the support plate 25 moves outward driven by the sliding shaft 24;

[0042] The support column 26 is located at the center of the outer side of the housing 11, and the slide slot 23 is opened relative to the slide shaft 24;

[0043] Since the slide slot 23 limits the slide shaft 24, the outer end of the support plate 25 can only move vertically driven by the slide shaft 24;

[0044] Working principle: When the outside world collides with the shell 11, since the outer ends of the two groups of support plates 25 are located outside the shell 11 under the support of the support columns 26, the outer ends of the support plates 25 are in contact with the outside world. The support plates 25 tilt and rotate inward under the collision, and drive the sliding shaft 24 to move along the outside of the slide groove 23. The movement of the lower end of the support plate 25 drives the telescopic spring 22 to be compressed. The compressed telescopic spring 22 generates elastic force to block the movement of the support plate 25, thereby weakening the force of the collision and preventing the outside world from directly contacting the shell 11.

[0045] See also Figure 4 As shown, this embodiment is based on the above embodiment and also includes:

[0046] A movable assembly, the movable assembly includes a support rod 31, a baffle 32, a first fixing slot 33, a second fixing slot 34, a first electromagnetic lock 35 and a second electromagnetic lock 36;

[0047] The support rod 31 is located at both sides of the housing 11, the baffle 32 is fixedly connected to the top of the support rod 31, the first fixing groove 33 is opened at the upper end of the support rod 31, the second fixing groove 34 is opened at the lower end of the support rod 31, the first electromagnetic lock 35 is fixedly connected to the upper end of the outer side of the housing 11, and the second electromagnetic lock 36 is fixedly connected to the lower end of the outer side of the housing 11;

[0048] The support rod 31 is used to support the baffle 32, and the baffle 32 is used to close the outer end of the housing 11. The first fixing groove 33 is used to correspond to the first electromagnetic lock 35, and the second fixing groove 34 is used to correspond to the second electromagnetic lock 36;

[0049] The first electromagnetic lock 35 and the second electromagnetic lock 36 are electrically connected to the leakage sensor through a circuit, and the baffle 32 is located outside the housing 11;

[0050] When the leakage sensor senses water immersion, the states of the first electromagnetic lock 35 and the second electromagnetic lock 36 can be controlled respectively;

[0051] Working principle: When the leakage sensor senses water immersion, it controls the knife gate 12 to open the gate. At this time, the leakage sensor controls the lock tongue of the first electromagnetic lock 35 to shrink and fall off from the first fixed groove 33. The support rod 31 is not blocked from moving downward under the action of gravity, and drives the baffle 32 to move downward. When the baffle 32 moves downward to close the outside of the shell 11, the leakage sensor controls the lock tongue of the second electromagnetic lock 36 to extend outward and enter the second fixed groove 34, so that the support rod 31 is fixed inside the shell 11, and the support rod 31 drives the baffle 32 to be fixed on the outside of the shell 11, so that the outside of the shell 11 is closed and the knife gate 12 cannot be operated.
