Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to an electromagnetic closing mechanism and method for a digital intelligent circuit breaker. Background Art

[0002] A circuit breaker is a switch device that can close, carry and interrupt the current under normal circuit conditions, and can close, carry and interrupt the 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. The boundary between high and low voltage is relatively vague, and those above 3kV are generally called high-voltage electrical appliances.

[0003] A Chinese patent with the authorization announcement number CN110993456B discloses a closing drive device and a closing system for a miniature circuit breaker, comprising: an active miniature circuit breaker and a plurality of slave miniature circuit breakers, wherein the active miniature circuit breaker is linked to the plurality of slave miniature circuit breakers through an assembly rod to realize the closing and opening of the plurality of slave miniature short-circuit breakers; the active miniature circuit breaker and the slave miniature circuit breaker respectively have a first handle and a second handle for controlling the closing and opening of the switches, wherein the first handle has a flip axis, and the active miniature circuit breaker enters a closing state after flipping upward along the flip axis, and enters an opening state after flipping downward, and the second handle also has a flip axis; and each opening and closing unit is touched by a second plug tongue to release the connection between the touched slave miniature circuit breaker and the assembly rod, so that the active miniature circuit breaker is linked to a certain number of slave miniature circuit breakers to realize automatic opening and closing.

[0004] In daily life, some circuit breakers are directly placed in environments with a lot of water mist, such as bathrooms and kitchens. The water mist absorbs heat during the rising process to form water droplets, which are distributed on the circuit breaker and can easily enter the interior of the circuit breaker, causing the circuit breaker to short-circuit, posing a safety hazard. For this reason, we design a closing mechanism for the circuit breaker to increase the waterproof performance of the circuit breaker. Summary of the invention

[0005] The object of the present invention is to provide an electromagnetic closing mechanism and method for a digital intelligent circuit breaker, aiming to solve the problem of poor waterproof performance of circuit breakers in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an electromagnetic closing mechanism of a digital circuit breaker, comprising a circuit breaker body, on which a handle is provided to realize opening or closing of the circuit breaker body; a cover body, movably mounted on the circuit breaker body to cover the handle; a connecting component, whose two ends are respectively connected to the cover body and the handle; and a first driving device, which drives the cover body to move and drives the handle through the connecting component to realize the opening or closing action.

[0007] A further technical solution of the present invention is that the cover can slide up and down along the height direction of the circuit breaker body.

[0008] A further technical solution of the present invention is that two opposite sides of the circuit breaker body are provided with sliding grooves, and the cover body is provided with a sliding part that slidably cooperates with the sliding grooves.

[0009] A further technical solution of the present invention is that the connecting assembly is a connecting rod, one end of the connecting rod is hinged to the cover body, and the other end of the connecting rod is hinged to the handle.

[0010] A further technical solution of the present invention is that the first driving device is two electromagnets 1, the two electromagnets 1 repel each other when powered on, one electromagnet 1 is fixedly arranged on the circuit breaker body, and the other electromagnet 1 is fixedly arranged on the cover.

[0011] A further technical solution of the present invention is that an opening is formed between the lower end of the cover body and the circuit breaker body, the cover body is provided with a bottom structure for opening or closing the opening, and also includes a second driving device for driving the bottom structure to open or close the opening.

[0012] A further technical solution of the present invention is that the bottom structure includes a T-shaped plate slidably connected to the cover body and an elastic member connected between the T-shaped plate and the inner wall of the cover body.

[0013] A further technical solution of the present invention is that the second driving device is two electromagnets 2 that attract each other, one of the electromagnets 2 is fixed on the T-shaped plate, and the other of the electromagnets 2 is fixed on the cover.

[0014] A digital intelligent circuit breaker electromagnetic closing method, characterized by comprising the following steps:

[0015] Step S10: energizing the two electromagnets 2 so that the two electromagnets 2 attract each other and open the opening;

[0016] Step S20: When the two electromagnets are energized, the cover slides up and down relative to the circuit breaker body, and the handle is driven by the connecting assembly to realize the opening or closing action.

[0017] The beneficial effects of the present invention are:

[0018] 1. When the gate needs to be opened or closed, the cover is driven to move by the first driving device, and the gate opening or closing action can be achieved without directly turning the handle, and the cover can always cover the handle to prevent water mist from rising and absorbing heat to form water droplets attached to the handle, thereby preventing water from entering the circuit breaker and causing a short circuit.

[0019] 2. When the bottom structure closes the opening, it can limit the cover from sliding upwards. When the bottom structure opens the opening, it can drive the cover to slide upwards to realize the gate opening action. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] like Figure 1 As shown, a digital circuit breaker electromagnetic closing mechanism includes: a circuit breaker body 10, on which a handle 11 is provided to open or close the circuit breaker body 10; a cover body 20, which is movably mounted on the circuit breaker body 10 to cover the handle 11; a connecting component 30, whose two ends are respectively connected to the cover body 20 and the handle 11; a first driving device 40, which drives the cover body 20 to move, and drives the handle 11 through the connecting component 30 to open or close the circuit breaker.

[0027] In this specific embodiment, when it is necessary to open or close the gate, the cover body 20 is driven to move by the first driving device 40, and the opening or closing action can be achieved without directly turning the handle 11, and the cover body 20 can always cover the handle 11 to prevent water mist from rising and absorbing heat to form water droplets attached to the handle 11, thereby preventing water from entering the circuit breaker and causing a short circuit.

[0028] In another specific embodiment of the present invention, the cover 20 can slide up and down along the height direction of the circuit breaker body 10 , and the circuit breaker body 10 can be opened or closed by sliding the cover 20 upward or downward without touching the handle 11 .

[0029] likeFigure 3 As shown, sliding grooves 12 are formed on two opposite sides of the circuit breaker body 10, and the cover body 20 is provided with a sliding part 21 that slidably cooperates with the sliding grooves 12.

[0030] Specifically, the connecting component 30 is a connecting rod. One end of the connecting rod is hinged to the cover body 20, and the other end is hinged to the handle 11. When the cover body 20 slides upward or downward, one end of the connecting rod rotates relative to the cover body 20, the other end rotates relative to the handle 11, and the included angle with the handle 11 changes, realizing the function of driving the handle 11 to rotate.

[0031] As Figure 2 shown, the first driving device 40 is two electromagnets I 41. The two electromagnets I 41 repel each other when energized. One electromagnet I 41 is fixedly arranged on the circuit breaker body 10, and the other electromagnet I 41 is fixedly arranged on the cover body 20. Wires (not shown in the figure) are provided on the two electromagnets 41. After the two electromagnets 41 are energized, a repulsive phenomenon occurs, forcing the cover body 20 to slide upward, thereby driving the handle to rotate upward to realize the opening action. When powered off, the cover body 20 slides downward under the action of gravity, driving the handle to rotate downward to realize the closing action. It should be noted that by changing the current direction, the two electromagnets 41 attract each other, which can quickly make the cover body 20 descend. When the two electromagnets 41 are always in the state of attracting each other, the movement of the cover body 20 can be restricted.

[0032] As Figure 4 shown, an opening 22 is formed between the lower end of the cover body 20 and the circuit breaker body 10. The cover body 20 is provided with a bottom structure 50 for opening or closing the opening 22, and further includes a second driving device 60 for driving the bottom structure 50 to open or close the opening 22. When the bottom structure 50 closes the opening 22, the upward sliding of the cover body 20 can be restricted. When the bottom structure 20 opens the opening 22, the cover body 20 can be driven to slide upward to realize the opening action.

[0033] Specifically, the bottom structure 50 includes a T-shaped plate 51 slidably connected to the cover body 20 and an elastic member 52 connected between the T-shaped plate 51 and the inner wall of the cover body 20.

[0034] Specifically, the second driving device 60 is two attracting electromagnets II 61. One electromagnet II 61 is fixed on the T-shaped plate 51, and the other electromagnet II 61 is fixed on the cover body 20. When the two electromagnets II attract each other, the elastic member 52 is compressed to open the opening 22. After the two electromagnets II are powered off, the opening 22 is closed under the action of the elastic member 52.

[0035] A digital intelligent circuit breaker electromagnetic closing method, characterized by comprising the following steps:

[0036] Step S10: Energize the two second electromagnets 61 so that the two second electromagnets 61 attract each other and open the opening 22;

[0037] Step S20: Energize the two first electromagnets 41 so that the cover body 20 slides up and down relative to the circuit breaker body 10, and drives the handle 11 through the connecting assembly 30 to perform the opening or closing operation.
