[0023] Working principle: When in use, the utility model uses a water pump and an external water supply pipeline to discharge water to the bottom end of the pressure tank 1 along the water inlet 3, and the water outlet 4 is connected to the ballast water tank through a connecting pipeline, so that when water is taken in to the bottom end of the pressure tank 1 along the water inlet 3 through the water pump and the external water supply pipeline, the water at the bottom end of the pressure tank 1 will enter the ballast water tank, so that water is replenished into the ballast water tank through the pressure tank 1, and at the same time, by turning on the external air pump, when the external air pump is turned on, the air will be exhausted and pressurized into the pressure tank 1 through the air inlet 5, and the internal gas pressure of the air pressure tank 1 entering the air inlet 5 can be controlled by the air pressure control valve 6. When the air is exhausted and pressurized into the pressure tank 1 through the air inlet 5, the air pressure will squeeze the water at the bottom end of the pressure tank 1, so that the internal pressure of the pressure tank 1 is consistent with the internal pressure of the ballast water tank, so that by adjusting and controlling the internal pressure of the pressure tank 1, it can be convenient to adjust and control the internal pressure of the ballast water tank;

[0024] At the same time, when the pressure inside the pressure tank 1 is adjusted and controlled, the water level inside the pressure tank 1 will change with the size of the pressure at the upper end of the pressure tank 1. When the water level inside the pressure tank 1 drops, the float 10 will move downward along the inner wall of the liquid level tube 8. When the float 10 moves downward, the float 10 will block the lower infrared sensor receiving end 14 through the transparent window 9, so that the lower infrared sensor receiving end 14 cannot receive the infrared signal emitted by the lower infrared sensor transmitting end 20. When the lower infrared sensor receiving end 14 cannot receive the infrared signal emitted by the lower infrared sensor transmitting end 20, a water shortage signal will be generated, so that the controller will automatically control the water pump to start the pressure The inside of the tank 1 is replenished with water. When the water pump is automatically turned on by the controller to replenish the inside of the pressure tank 1 with water, the float 10 will move upward along the liquid level tube 8. When the float 10 moves upward, the float 10 will block the upper infrared sensor receiving end 26 through the transparent window 9. The upper infrared sensor receiving end 26 cannot receive the infrared signal emitted by the lower infrared sensor transmitting end 20, and a full water signal will be generated, so that the water pump is automatically turned off by the controller to replenish the inside of the pressure tank 1 with water, so that it is easy to adjust and control the internal pressure of the ballast water tank, and the pressure tank 1 is automatically replenished with water, so that the internal pressure of the pressure tank 1 and the ballast water tank remains stable;

[0025] At the same time, by rotating the first adjusting screw 15 and the second adjusting screw 22 respectively, when the first adjusting screw 15 and the second adjusting screw 22 rotate, the force generated by the threaded connection will drive the first upper slider 17, the first lower slider 18, the second upper slider 24, and the second lower slider 25 to move linearly inward or outward synchronously. When the first upper slider 17, the first lower slider 18, the second upper slider 24, and the second lower slider 25 move linearly inward or outward synchronously, the upper infrared sensor transmitting end 19, the lower infrared sensor transmitting end 20 and the lower infrared sensor transmitting end 20, the lower infrared sensor receiving end 14 will be driven to move linearly inward or outward synchronously, thereby achieving the effect of adjusting the distance between the upper infrared sensor transmitting end 19, the lower infrared sensor transmitting end 20 and the lower infrared sensor transmitting end 20, the lower infrared sensor receiving end 14.
