Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a suction port device with a built-in collection cabinet. Background Technology

[0002] Ships have many liquid tanks, and suction ports are designed at the end of the pipelines when pumping liquids. Traditionally, the suction port is placed at the lowest position of the liquid tank to achieve the function of pumping liquids from the tank. However, this technology still has some drawbacks:

[0003] 1. When the suction port is placed at the lowest point inside the tank, space needs to be left below the suction port to pump out the liquid, so it is impossible to completely pump out the liquid inside the tank. For flat-bottomed liquid tanks with a large capacity, a relatively large amount of residual liquid will not be pumped out.

[0004] 2. When there are two or more lowest points in a liquid tank, the traditional design requires the design of suction ports at these lowest points, and each suction pipe needs to be equipped with a valve. When a higher suction point is reached, the valve needs to be closed to prevent air from being sucked in. This design and operation are quite cumbersome in practical applications.

[0005] 3. When using a suction inlet to draw in bilge water from a room, the suction inlet should be designed at the lowest point in the room. According to regulations, the suction inlet must be placed in a container with a volume of not less than 0.3 m³. 3 A sewage well is usually a structural sewage well added at the bottom of the room. The placement of this sewage well requires structural considerations of strength and space. Sometimes, due to space constraints, it is not possible to place a sewage well. Utility Model Content

[0008] The suction device includes a collection cabinet body, the inside of which is a sealed cavity, and a suction port is provided in the sealed cavity.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1-4 As shown, this utility model provides a suction inlet device with a built-in collection cabinet. The suction inlet device includes a suction inlet device 1, a suction pump 10 and a suction valve 20. The suction valve 20 is connected to the suction port of the suction pump 10 through a pipeline, and the suction inlet device 1 is connected to one end of the suction valve 20 through a pipeline.

[0025] The suction device 1 includes a collection cabinet 2, inside which is a sealed cavity 21. A suction port 11 is located within the sealed cavity 21, and a suction flange 111 is attached to one end of the suction port 11. A suction valve 20 is fixed to the suction flange 111 via a pipeline. When the suction pump 10 and the suction valve 20 are opened, the suction pump 10 can draw liquid from the sealed cavity 21 through the suction valve 20. A first inflow flange 12 and a second inflow flange 13 are respectively mounted on one side of the collection cabinet 2. Inflow flange 13 is connected to inflow flange 12, and inflow valve 14 is connected to inflow flange 12. Inflow valve 15 is connected to inflow flange 13. By configuring inflow flange 12, inflow flange 13, inflow valve 14, and inflow valve 15, the pipes at the ends of inflow valve 14 and inflow valve 15 are respectively installed at the two lowest points at the bottom of liquid tank 30. Liquid inside liquid tank 30 can pass through the pipes, inflow flange 12, and inflow flange 15. The inflow flange 13 enters the sealed cavity 21. Inflow valve 14 controls the opening and closing of inflow flange 12, and inflow valve 15 controls the opening and closing of inflow flange 13. A vent valve 16 is installed on the top of the collection cabinet 2, with one end connected to the sealed cavity 21. By opening the vent valve 16, air can be discharged from the sealed cavity 21. A vent plug 17 is detachably installed at the bottom of the collection cabinet 2. By setting a drain plug 17, the liquid in the sealed cavity 21 can be discharged outward through the drain plug 17 after the drain plug 17 is opened. A manhole cover 18 can be detachably installed on the side of the collection cabinet 2 away from the No. 1 inflow flange 12. By setting a manhole cover 18, the sealed cavity 21 can be easily cleaned and maintained after the manhole cover 18 is opened. An observation mirror 19 is installed on the collection cabinet 2. By setting an observation mirror 19, it is easy for the operator to observe the liquid level in the sealed cavity 21.

[0026] Working principle: When in use, first assemble the pipes at the ends of No. 1 inflow valve 14 and No. 2 inflow valve 15 at the two lowest points at the bottom of the liquid tank 30.

[0027] Subsequently, when the liquid is first drawn in, the vent valve 16 is opened, and the No. 1 inflow valve 14 and the No. 2 inflow valve 15 are opened to purge the air from the sealed cavity 21.

[0028] The liquid level in the sealed cavity 21 is observed through the observation mirror 19. When the liquid level reaches the top, the vent valve 16 is closed. At this time, the suction valve 20 is opened and the suction pump 10 is started to complete the suction of liquid in the liquid chamber 30.

[0029] When the sealed cavity 21 needs to be maintained and cleaned, close the No. 1 inflow valve 14 and the No. 2 inflow valve 15, open the vent valve 16, place an external water collection bucket at the bottom of the drain plug 17, then open the drain plug 17 to drain the liquid in the sealed cavity 21, open the manhole cover 18, and clean and maintain the sealed cavity 21.

[0030] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
