[0002] Liquid tanks and piping systems are essential components of ships, especially for specialized vessels. Ensuring their proper functioning is a crucial inspection item. To prevent liquids at the bottom of pipes and tanks from affecting their normal operation, an adjustable automatic drainage device is needed to strictly control the liquids remaining in the original system.

[0003] Most automatic drainage devices currently on the market rely on electrically controlled water pumps for liquid level regulation. Traditional automatic drainage devices have several drawbacks: 1. They are overly complex, resulting in high installation and maintenance costs. 2. They have high operating conditions and are unsuitable for harsh environments. 3. Their application range is limited, and they cannot control the drainage threshold. Summary of the Invention

[0005] Furthermore, the negative pressure device includes a negative pressure plate disposed inside the water tank and matching the horizontal cross-section of the water tank, the negative pressure plate being able to move vertically along the water tank; by vertically moving the negative pressure plate, the pressure below the negative pressure plate can be adjusted.

[0006] Furthermore, a liquid level control rod is vertically provided on the upper surface of the negative pressure plate, and the liquid level control rod extends out from the top of the water tank.

[0007] Furthermore, the liquid level control rod has a handle at its end located outside the water tank.

[0008] Furthermore, the liquid level control rod is connected to a power device at the outward end of the water level.

[0009] Furthermore, the hole at the top of the water tank through which the liquid level control rod passes is a screw hole, and the liquid level control rod is a screw that mates with the screw hole.

[0010] Furthermore, the liquid level control rod is provided with a scale to indicate the volume of the space below the negative pressure plate where the water tank is located.

[0011] Furthermore, the water tank is provided with an observation window made of transparent material to display the position of the negative pressure plate.

[0012] Furthermore, a support frame is provided below the water tank.

[0013] The adjustable automatic drainage device provided by this invention has the following advantages over the prior art: This invention can effectively solve the problem of liquid not being able to drain from the bottom of the pipeline and liquid tank in ships. The device is simple to operate, small in size, highly flexible and low in manufacturing cost, and effectively solves the drainage problem of the bottom of the pipeline and liquid tank in ships. Attached Figure Description

[0014] Figure 1 This is a schematic diagram illustrating the principle of the present invention. Detailed Implementation

[0015] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Reference Figure 1 This application proposes an adjustable automatic drainage device. The product consists of a base, a drain outlet, an opening and closing device, a water tank, a liquid level control rod, and other equipment. The water tank is equipped with a negative pressure device to maintain a negative pressure state inside the water tank. The water tank includes a drain outlet and an equipment connection port, and the drain outlet is equipped with an opening and closing device.

[0017] The negative pressure device includes a negative pressure plate installed inside the water tank and matching the horizontal cross-section of the water tank. The negative pressure plate can move vertically along the water tank. By vertically moving the negative pressure plate, the pressure below the negative pressure plate can be adjusted. A liquid level control rod is vertically installed on the upper surface of the negative pressure plate and extends out from the top of the water tank.

[0018] The liquid level control lever has graduations to indicate the volume of the water tank in the space below the negative pressure plate. The water tank has a transparent observation window to display the position of the negative pressure plate. This structure allows the operator to adjust the negative pressure plate to the desired liquid level and flexibly control the system according to the drainage environment.

[0019] In some embodiments of this application, the end of the liquid level control rod located outside the water tank is provided with a handle. With the help of a small-volume water tank, it can be used in some narrow cabin interior application scenarios, and the area under the negative pressure plate can be made to be in a negative pressure state by human power.

[0020] In some other embodiments of this application, the liquid level control rod is connected to a power device at the water-facing end, and in conjunction with a large-volume water tank, the power is provided by an external device to keep the area below the negative pressure plate in a negative pressure state.

[0021] In some other embodiments of this application, the hole through which the liquid level control rod passes at the top of the water tank is a screw hole, and the liquid level control rod is a screw that mates with the screw hole; correspondingly, the connection between the liquid level control rod and the negative pressure plate is a rotatable connection, so that as the liquid level control rod rotates around the axial direction, only the height of the negative pressure plate is adjusted, and the negative pressure plate does not rotate with the liquid level control rod.

[0022] The operating steps and working principle of this application are as follows: 1) Operating steps: Connect the equipment interface ⑥ to the equipment → lower the liquid level control rod to the bottom of the water tank → close the opening and closing device ③ → pull up the liquid level control valve ⑤ to the expected liquid level height → open the opening and closing device ③ to discharge the waste liquid.

[0023] 2) Working principle Connect the equipment interface ⑥ to the equipment and close the opening and closing device ③ to form a closed space between the equipment to be drained and the drainage device. Pull up the liquid level control valve ⑤ to the expected liquid level height to generate negative pressure in the drainage device, thereby sucking out the waste liquid at the bottom of the equipment. Open the opening and closing device ③ to discharge the waste liquid.

[0024] It should be noted that the appendix Figure 1 This is only for the purpose of showing the position and connection relationship of each structure in this application, and does not limit the specific structure of each structure. For example, the water tank is not limited to the rectangular water tank shown in the figure, and the negative pressure plate is not drawn in the figure.

[0025] In summary, these are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope of the present invention.
