Technical Field

The invention relates to the technical field of medium-sized deep sea equipment trim balance, in particular to an immersion type double-pump trim balance system.

Background

The trim balance system is a system which adjusts the trim moment of a submarine or a submersible vehicle by adjusting the water quantity in a bow balance water tank and a stern balance water tank so as to ensure the normal posture of the submersible equipment. Mainly comprises a front water tank, a rear water tank, a pipeline, a valve, a pump or a medium-pressure gas source and the like. At present, a submarine uses medium-pressure gas to press water, and the submarine uses a water pump to adjust water. The system for pressurizing water by adopting medium-pressure gas is generally provided with a reversing valve group formed by combining 4 two-position two-way gas valves, the medium-pressure gas is subjected to reversing water pressurization, and two electric valves are used for controlling the connection and the disconnection of a water pipeline; the water pump is mainly adopted for water pumping and is arranged in a midship position of the submersible, and the valve box is used for controlling the water pumping direction of the water pump. When the pitching occurs, the water pump pumps water.

At present, the conventional trim balancing system of the medium-sized deep sea equipment has the following problems:

(1) the displacement of the medium-sized deep sea equipment is generally smaller than that of a submarine, but is larger than that of a common submersible. The medium-pressure air pressure water is used, the flow is large, the water regulating precision is difficult to control, and the influence on the pitching balance effect of the medium-sized deep sea equipment is large;

(2) when a single water pump is adopted, the water pump is arranged in a midship, and when equipment is in a longitudinal inclination angle, a certain distance is reserved between a water inlet of the water pump and the liquid level of the water cabin, and a self-sucking water pump is needed. If the water absorption height difference reaches 5 m or more, the water absorption height difference brings difficulty to the water suction of the self-sucking water pump, even the water suction cannot work, and the length of the medium-sized deep sea equipment is limited.

(3) The self-priming water pump increases the water pumping time along with the increase of the self-priming height, and the water outlet quantity gradually decreases. This also increases the balancing time of the pitch balancing system.

Disclosure of Invention

The applicant provides an immersion type double-pump trim balance system with a reasonable structure aiming at the defects in the prior art, and solves the problem that the water volume shifting precision of the air conditioner for the medium-sized deep sea equipment is poor or the water regulation by a self-sucking pump is influenced by the water level difference.

The technical scheme adopted by the invention is as follows:

an immersion type double-pump trim balance system comprises a stern water tank and a bow water tank, wherein the stern water tank and the bow water tank are connected through a main pipe, two tail ends of the main pipe are respectively connected with a first water pump and a second water pump, two ends of the main pipe are respectively connected with a first branch pipe and a second branch pipe in parallel, the tail ends of the first branch pipe and the second branch pipe are respectively connected to the stern water tank and the bow water tank, a first valve is arranged on the first branch pipe, and a second valve is arranged on the second branch pipe; and the middle part of the main pipe is provided with a flowmeter.

As a further improvement of the above technical solution:

the top parts of the stern water tank and the bow water tank are respectively connected to the plug valves through pipelines, and silencers are further arranged on the pipelines.

The first valve and the second valve are electrically operated valves.

The invention has the following beneficial effects:

the invention has compact and reasonable structure, is beneficial to improving the water transfer efficiency, has high water transfer speed and high water quantity precision, is not limited by the length of equipment, and is suitable for medium-sized deep sea equipment with water discharge. Compared with the conventional medium-pressure air longitudinal-inclination balance system, the system adopts the pump to adjust water, the flow meter monitors the flow, the flow is stable and controllable, and the water adjusting precision is improved conveniently; compare with conventional pump accuse pitch balanced system, avoid adopting self priming pump, reduce the self priming parameter requirement to the water pump, adopt the double pump simultaneously, and the pump soaks in the sump, the sump of not only being convenient for integrates the design, simplifies the outside water pipeline of pitch system, can select the water pump of suitable lift according to equipment length moreover, avoids the pitch system to receive equipment length's influence. Meanwhile, the invention also has the following advantages:

(1) the invention is convenient for the integrated design of the water tank water pump power source, simplifies the external water pipeline and has simple structure.

(2) The invention can stabilize the water regulating speed and improve the water regulating precision.

(3) The invention can reduce the requirement of the pump control trim balance system on the self-suction capacity of the pump, cancel the restriction of the water level difference of the fore and aft water tanks, and is more convenient to apply.

(4) The invention is suitable for medium-sized deep sea equipment with water displacement and has good application prospect.
