[0018] The beneficial effects of this utility model are:

[0019] Through further design optimization, this utility model not only improves the safety performance of the electrical protector in a water immersion environment, but also enhances the stability and functionality of its overall structure, specifically in the following aspects:

[0020] Firstly, the protective components not only provide effective physical shielding for the main body of the power protector, preventing direct impact from external water flow, but also enable automatic power-off protection when water immersion is detected through the intelligent linkage between the electric cylinder and the immersion sensor, further reducing the risk of electric shock. At the same time, the baffle effectively limits the movement range of the baffle, ensuring that the working end of the electric cylinder can accurately press the reset button on the main body of the power protector, improving the reliability and response speed of the system.

[0021] Secondly, by setting up the support and reset assembly, not only is stable support for the arc-shaped mesh plate achieved through the combination of slider, support rod and arc-shaped sealing plate, but also the automatic reset function of the arc-shaped sealing plate is achieved through the clever cooperation of guide rod and reset spring. This design not only simplifies the operation process and improves the ease of use, but also cleverly adjusts the opening and closing state of the air outlet through the setting of the wind baffle when the fan is working, effectively improving the heat dissipation efficiency. At the same time, it can prevent external water from entering the housing when water immersion occurs, and facilitates the drainage operation of water that enters the housing.

[0022] Furthermore, the water-blocking components, especially the combination of strip plates, L-shaped plates, limit bolts, and water-blocking pads, provide a comprehensive protective barrier for the wiring holes of the main body of the power protector. The silicone material of the water-blocking pad not only has good sealing performance, but also deforms when subjected to external pressure, thus better adapting to wires of different thicknesses and ensuring a sealing effect. The water-blocking plug further enhances the waterproof capability of the housing's inlet hole, effectively preventing the intrusion of external moisture.

[0023] In summary, the electrical protector with a water-immersion anti-electric shock structure proposed in this utility model has outstanding performance in ensuring electrical safety, improving equipment stability, optimizing heat dissipation efficiency, and preventing electric shock during water immersion, providing users with safer and more reliable electrical protection.

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Reference Figure 1-7An electrical protector with a water-immersion anti-electric shock structure includes a housing 1, an arc-shaped mesh plate 12, an electrical protector body 2, a mounting plate 21, a fan 5, an electric cylinder 44, and a water immersion sensor 45. One side of the housing 1 is open and hinged with a door 11. The front and rear sides of the door 11 are in movable sealing contact with the inner walls of the front and rear sides of the opening of the housing 1. An air inlet and an air outlet are respectively opened on the top inner wall and the bottom inner wall of the housing 1. The arc-shaped mesh plate 12 is fixedly installed in the housing 1 and adapted to the air outlet. The mounting plate 21 is fixedly installed in the housing 1. The electrical protector body 2 is fixedly installed on the mounting plate 21.

[0035] An arc-shaped opening is provided on the mounting plate 21, and an arc-shaped baffle 4 is slidably installed inside the arc-shaped opening. An elastic spring 43 is fixedly installed on the bottom side of the baffle 4 away from the main body 2 of the power protector. The elastic spring 43 is fixedly installed on the side of the mounting plate 21 away from the main body 2 of the power protector. The electric cylinder 44 and the water immersion sensor 45 are both fixedly installed on the baffle 4, which can provide shielding and protection for the main body 2 of the power protector, and at the same time provide stable support for the electric cylinder 44 and the water immersion sensor 45. A stop bar 42 is fixedly installed on the baffle 4, and the stop bar 42 moves and abuts against the side of the mounting plate 21 away from the main body 2 of the power protector, which can provide a limiting effect for the baffle 4 and prevent the working end of the electric cylinder 44 from being misaligned with the reset button of the main body 2 of the power protector. The working end of the electric cylinder 44 and the reset button of the main body 2 of the power protector are located on the same axis, and the water immersion sensor 45 is electrically connected to the electric cylinder 44 through the controller, which can realize the effect of water immersion monitoring and can cut off the power in time after detecting water immersion, thereby achieving the purpose of preventing electric shock.

[0036] The fan 5 is fixedly installed on the mounting plate 21. The mounting plate 21 has a groove on the side near the main body 2 of the power protector. A slider 63 is slidably installed in the groove. A support rod 6 is fixedly installed on the slider 63. The bottom end of the support rod 6 extends to the bottom of the arc-shaped mesh plate 12 and is fixedly installed with an arc-shaped sealing plate 61. The support rod 6 and the arc-shaped mesh plate 12 are slidably connected. A guide rod 64 is fixedly installed in the groove and is slidably connected to the slider 63. A return spring 65 is movably sleeved on the outside of the guide rod 64. The two ends of the return spring 65 are fixedly connected to the bottom inner wall of the groove and the bottom side of the slider 63, respectively. It can control the slider 63 to drive the arc-shaped sealing plate 61 to return upward through the support rod 6. The top end of the support rod 6 extends to the bottom of the air outlet of the fan 5 and is fixedly installed with a baffle plate 62. When the fan 5 is working, it can control the baffle plate 62 to drive the arc-shaped sealing plate 61 to disengage from the arc-shaped mesh plate 12 through the support rod 6. This enables the fan 5 to automatically adjust the opening and closing of the air outlet according to its working state.

[0037] A strip plate 3 is fixedly installed on the bottom side of the wiring terminal of the main body 2 of the power protector. Multiple limiting bolts 32 extending into the wiring hole are threaded on the main body of the power protector. An L-shaped plate 31 is rotatably installed on each of the multiple limiting bolts 32. An arc groove is opened on the side of the strip plate 3 and the multiple L-shaped plates 31 that are close to each other. There are multiple arc grooves on the strip plate 3 and they correspond to the arc grooves on the multiple L-shaped plates 31. A water-blocking pad 33 is fixedly installed on the inner wall of the multiple arc grooves. The multiple water-blocking pads 33 are in movable sealing contact with the outside of the wire extending from the wiring hole of the main body 2 of the power protector, which can prevent water from entering the wiring hole of the main body 2 of the power protector. The water-blocking pads 33 and water-blocking plugs 34 are both made of silicone. The silicone material not only has good sealing performance, but can also deform when squeezed by external force, so as to better adapt to wires of different thicknesses and ensure the sealing effect.

[0038] In this embodiment, in order to provide stable guidance for the baffle 4, two rotating shafts arranged in parallel are rotatably installed on the inner walls of the front and rear sides of the arc-shaped opening. Multiple guide wheels 41 are fixedly sleeved on both rotating shafts, and the multiple guide wheels 41 are in rolling contact with the bottom side of the baffle 4.

[0039] In this embodiment, to prevent water from entering the inlet hole, the housing 1 is provided with multiple inlet holes on the side away from the door 11. Each inlet hole is provided with a water-blocking plug 34, and the wires connected to the main body 2 of the power protector pass through the corresponding water-blocking plugs 34.

[0040] The electric cylinder, fan, main body of the power protection device, and the circuits, electronic components and module mechanisms involved are all based on existing technology, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software, circuits and methods.

[0041] Working principle: When in use, first turn on the power supply, and the power protector will immediately enter the standby state. At this time, the fan 5 is in a non-working state. Under the elastic force of the return spring 65, the wind baffle 62 pushes the support rod 6 and the arc-shaped sealing plate 61 to stick tightly to the bottom of the arc-shaped mesh plate 12, sealing the air outlet and effectively preventing external dust or foreign objects from entering the housing 1, ensuring the cleanliness and safety of the electrical environment.

[0042] When the electrical equipment is operating normally and there is no water immersion, the water immersion sensor 45 will not trigger a signal to the controller, the electric cylinder 44 will remain stationary, and the baffle 4 will be held in its initial position by the elastic force of the elastic spring 43. This will not affect the reset button of the main body 2 of the power protector, ensuring that the normal function of the power protector is not interfered with.

[0043] However, once the electrical environment is flooded, the water immersion sensor 45 immediately senses the moisture and sends a signal to the controller. The controller then controls the electric cylinder 44 to start. The working end of the electric cylinder 44 precisely presses the reset button on the main body 2 of the power protector to achieve emergency power cut-off and effectively prevent electric shock accidents.

[0044] After a power outage, if the power protector needs to be reactivated, first open the casing door 11, then lift the baffle 4 upwards. The baffle 4 moves to the upper left and maintains a stable movement under the guidance of the guide wheel. At the same time, a force is applied to the elastic spring 43, causing the baffle 4 to remove its obstruction of the reset button on the main body 2 of the power protector. The operator can then manually reset it. After resetting, slowly release the baffle 4. Under the reaction force of the elastic spring 43, the baffle 4 resets and restores its obstruction of the main body 2 of the power protector, preparing for the next power protection task.

[0045] In addition, when heat dissipation or maintenance is required, the fan 5 can be started. The start of the fan 5 drives the airflow into the housing 1 from the air inlet. The airflow impacts the baffle plate 62, which overcomes the elastic force of the return spring 65 and drives the arc-shaped sealing plate 61 to separate from the arc-shaped mesh plate 12 through the support rod 6. At this time, the air outlet is opened and the airflow is discharged smoothly, effectively reducing the temperature inside the housing 1 and protecting the internal electrical components from high temperature damage. When the fan 5 stops working, the return spring 65 automatically resets the arc-shaped sealing plate 61 and re-closes the air outlet.

[0046] By installing a water-blocking plug 34 in the inlet hole and using a strip plate 3 in conjunction with an L-shaped plate 31 and a water-blocking pad 33 at the wiring terminal of the main body 2 of the power protector, not only is the impact on the wire connection avoided, but moisture is also effectively prevented from entering the power connection hole of the main body 2 of the power protector from the wiring hole, thus ensuring stable operation of the equipment and personnel safety.

[0047] The present invention provides a detailed description of an electrical protector with a water-immersion anti-electric shock structure. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
