[0002] In modern life, the problem of electrical safety has always been highly concerned. Especially in some special environments, such as basements, garages, outdoors, etc., due to various reasons, water may invade electrical equipment, thus triggering electric shock accidents. Although traditional circuit breakers can protect electrical safety to a certain extent, in a waterlogged environment, their water-proof performance is often insufficient and cannot effectively prevent electric shock accidents. Therefore, there is an urgent need in the market for a circuit breaker that can effectively protect electrical equipment in a waterlogged and water-inlet environment.

[0003] In the prior art, although there are some water-proof circuit breakers, they usually only have basic water-proof functions, lack targeted designs for waterlogged environments, and these water-proof circuit breakers often cannot give an alarm in time after water ingress, resulting in users being unable to take measures in time and increasing potential safety hazards.

[0004] Therefore, the utility model proposes an electric protector for a circuit breaker against water immersion, water-proof and electric shock to solve the above problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions of the present utility model in combination with specific embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0028] Refer to Figures 1-4, an electric protector for a circuit breaker against waterlogging, waterproofing and electric shock, comprising a housing 1, a housing door 11, a rotating plate 13 and a circuit breaker main body 2. An installation opening is formed in the housing 1, and the housing door 11 is hingedly installed in the installation opening. The circuit breaker main body 2 is fixedly installed in the housing 1. A plurality of inlet holes are formed in the bottom inner wall of the housing 1 directly below the wiring part of the circuit breaker main body 2. In order to avoid the influence on the wires when water enters the housing 1, a wire bundling tube 12 is fixedly installed in the inlet holes. A drain port is formed at the lowest point of the bottom of the housing 1. The same rotating shaft 131 is rotatably installed on the inner walls on the front and rear sides of the drain port. The rotating plate 13 is radially fixedly installed on the rotating shaft 131. A water level sensor 31 is fixedly installed on the bottom inner wall of the housing 1, and a controller 3 is fixedly installed on the circuit breaker main body 2. The water level sensor 31 is used to detect the water level height inside the housing 1, and the controller 3 is used to receive the signal of the water level sensor 31 and control the on-off state of the circuit breaker main body 2 according to the signal;

[0029] An installation groove is formed at the lower position on the outer side of the housing 1, and an audible and visual alarm 32 electrically connected to the controller 3 is fixedly installed in the installation groove. When the water level sensor 31 detects that the water level exceeds the preset safe water level, the controller 3 controls the audible and visual alarm 32 to emit an audible and visual alarm signal to remind the user to timely deal with the accumulated water problem, thereby avoiding the occurrence of electric shock accidents. A guide rod is fixedly installed on the handle of the circuit breaker main body 2. A strip-shaped plate 4 is vertically slidably installed on the bottom inner wall of the housing 1. A guide frame 41 is fixedly installed on the top side of the strip-shaped plate 4. The guide rod extends into the guide frame 41 and is in movable contact with the inner side wall of the guide frame 41, so that the handle of the circuit breaker main body 2 can be controlled by controlling the strip-shaped plate 4. The bottom side of the strip-shaped plate 4 extends below the housing 1 and is fixedly installed with a pressing block 42, which is convenient for the operator to directly reset the circuit breaker main body 2 to the power-on state without opening the housing door 11.

[0030] In this embodiment, in order to avoid scratches on the strip-shaped plate 4 when the operator operates it and reduce the discomfort during operation, the pressing block 42 is made of insulating rubber.

[0031] In this embodiment, in order to avoid excessive deflection of the rotating plate 13, a limiting strip 132 is fixedly installed on the inner wall of one side of the drain port. The limiting strip 132 is located below the rotating plate 13 and can provide a limit for the rotating plate 13, so as to avoid excessive deflection of the rotating plate 13.

[0032] In this embodiment, in order to not affect the drainage from the housing 1 to the outside while being able to timely close the drain port under the action of buoyancy when the housing 1 is waterlogged, thereby greatly reducing the speed of water entering the housing 1, the rotating plate 13 is made of a lightweight foam board.

[0033] In this embodiment, in order to provide stable support for the circuit breaker body 2 while preventing water on the side wall of the housing 1 from invading the circuit breaker body 2, a plurality of support blocks 21 arranged in a V shape are fixedly installed on the back side of the circuit breaker body 2, and the plurality of support blocks 21 are all fixedly installed on the side wall of the housing 1.

[0034] In this embodiment, in order to facilitate observing the situation of the circuit breaker body 2 in the housing 1 without opening the housing door 11 and at the same time facilitate the opening and closing operation of the housing door 11, an observation window 111 is provided on the housing door 11, and a handle 112 is fixedly installed on the housing door 11.

[0035] For the controllers, water level sensors, audible and visual alarms involved, as well as the circuits, electronic components, and module mechanisms required during the installation process, etc., existing technologies are adopted, which can be fully realized by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software, circuits, and methods.

[0036] Working principle: When in use, first install the housing 1 at the required position. When water enters the housing 1, the water is directly discharged through the drain port. When the housing 1 is in a flooded state, since the rotating plate 13 is made of a lightweight foam board, the rotating plate 13 can close the drain port under the action of buoyancy, thereby reducing the water inflow speed. When the water in the housing 1 reaches the position of the water level sensor 31, the water level sensor 31 feeds back and sends a signal to the controller 3. The controller 3 controls the audible and visual alarm 32 to give an audible and visual warning to remind the user to deal with the accumulated water in time and at the same time controls the circuit breaker body 2 to cut off the power, thereby avoiding the occurrence of electric shock accidents. Through the setting of the cable duct 12, the wires connected to the circuit breaker body 2 can be prevented from being invaded by water. When the user eliminates the danger, by pressing the pressing block 42, the strip plate 4 is controlled to drive the guiding frame 41 to move upward, so that the circuit breaker body 2 can be directly controlled to return to the powered-on state under the cooperation of the guiding rod, and the operation can be carried out without opening the housing door 11, greatly improving the convenience of user operation.

[0037] The above has introduced in detail a power protector for a circuit breaker against flooding, water resistance, and electric shock provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
