Description

Novel gravity discharge anchor chain cabin structure

Technical Field

The invention relates to the technical field of ships, in particular to a novel gravity-discharging chain locker structure.

Background

Most ships are equipped with anchor chains for anchoring and positioning of the ships. The chain locker is a cabin for storing chain, generally arranged at the head of the ship, and also provided with a tail anchor, and the chain locker is arranged at the tail of the ship. The chain locker is usually watertight with respect to the other compartments of the vessel. The bottom in chain locker sets up the mud cabin usually, when boats and ships anchor chain was packed up, though can wash during the chain pipe, still can follow seabed area upper portion mud and sea water to bring into the chain locker, mud deposits in the chain locker, and the sea water then gets rid of the outboard through the scavenging cabin pump, and every process a period all needs the manual work to open the bilge cover in chain locker below mud cabin, carries out artifical clearance to mud, consumes manpower and materials.

Usually hawse cabin upper portion is hawse chain storage space, the structure trompil platform is established to the basement, the below is the sludge cabin, the liquid level warning is established to the under-deck, when the warning of anchor chain under-deck liquid level, open and sweep the control valve on the cabin pipe, start the fire pump, fire water passes through hawse cabin jet pump, produce the pressure differential, discharge the water of hawse cabin bottom to the outboard, after sludge accumulation to certain degree, then open the manhole cover that sets up at the sludge cabin, the crew is artifical clears up mud, because seabed mud also often gives off foul smell, produce the pollution to adjacent cabin during the clearance, sludge cabin space is also narrow and small relatively, be difficult to accomplish thoroughly the sanitization.

The existing chain locker structure has the following problems:

1. high cost, and the need of arranging a jet pump for cleaning the cabin, corresponding piping, manhole cover cleaning and the like

2. Low efficiency, automatic cleaning, consumption of electric energy on board, etc

3. High labor intensity, narrow space of sludge cabin and inconvenient manual operation

4. The operation environment is poor, the seabed sludge often emits foul smell, and the secondary pollution of other cabins of the ship can be caused

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the novel gravity-discharge chain locker structure, which can automatically discharge and clean by gravity, save a cabin-sweeping pump and a pipe system, save the ship construction cost, improve the crew operation environment and save the ship chain locker cleaning cost because manual cleaning is not needed, and can not influence the ship stability.

In order to achieve the above object, the present invention provides a novel gravity-discharging chain locker structure, comprising: at least one chain locker body and at least one sewage draining pipe; the chain locker body is formed in a ship body, and the bottom of the chain locker body is in a funnel shape with a large top and a small bottom; the first end of the sewage discharge pipe is connected with the bottom end of the anchor chain cabin body, and the second end of the sewage discharge pipe is communicated with the outside of the ship body; the height of the first end of the sewage draining pipe is larger than that of the second end of the sewage draining pipe.

Preferably, the sewage treatment device further comprises at least one isolation valve, and the isolation valve is arranged on the sewage discharge pipe.

Preferably, the sewage draining pipe is made of watertight steel pipe.

Preferably, the sewage treatment device further comprises at least one dredging flange, and the dredging flange is mounted on the sewage discharge pipe.

Due to the adoption of the technical scheme, the invention has the following beneficial effects:

the bottom of the anchor chain cabin body is directly made into a funnel shape and is directly communicated with the outside of the ship body, and seawater and sludge in the sludge cabin can be directly discharged to the outside of a ship board through gravity.

1. The structure is simple, and a complex piping system is not required to be arranged;

2. the construction cost is low, and a cabin sweeping jet pump, a piping system and the like are omitted;

3. the operation is simple, the gravity type discharge form is adopted for automatic discharge, and manual intervention is not needed;

4. can reduce the operation intensity of the crew and improve the operation environment of the crew.

fig. 2 is a second directional structural schematic diagram of the novel gravity drainage chain locker structure according to the embodiment of the invention.

Detailed Description

The following description of the preferred embodiments of the present invention, with reference to the accompanying drawings 1 and 2, will provide a better understanding of the function and features of the invention.

Referring to fig. 1 and 2, a novel gravity-discharging chain locker structure according to an embodiment of the present invention includes: at least one chain locker body 1 and at least one sewage draining pipe 2; the chain locker body 1 is formed in a ship body 3, and the bottom of the chain locker body 1 is in a funnel shape with a large top and a small bottom; the first end of the blow-off pipe 2 is connected with the bottom end of the anchor chain cabin body 1, and the second end of the blow-off pipe 2 is communicated to the outside of the ship body 3; the height of the first end of the sewage draining pipe 2 is larger than that of the second end of the sewage draining pipe 2.

Make the shape of funnel with anchor chain cabin body 1 bottom, can prevent the mud accumulation, the bottom sets up blow off pipe 2 UNICOM to the hull 3 outside, as outboard discharge hole.

The device also comprises at least one isolating valve 4, and the isolating valve 4 is arranged on the sewage draining pipe 2.

In the design of less boats and ships, the anchor chain cabin body 1 degree of depth is great, because the export of blow off pipe 2 is less apart from the surface of water distance, increases isolating valve 4 on blow off pipe 2, prevents that the sea water from flowing backward into anchor chain cabin body 1. In the design of a large ship, the depth of the chain locker body 1 is relatively small, the distance between the outlet position of the sewage discharge pipe 2 and the water surface is large, and the isolating valve 4 can not be arranged.

The sewage draining pipe 2 is made of watertight steel pipe.

The dredging device also comprises at least one dredging flange, and the dredging flange is arranged on the sewage discharge pipe 2.

According to the novel gravity discharge anchor chain cabin structure provided by the embodiment of the invention, the bottom of the anchor chain cabin body 1 is directly made into a funnel shape and is directly communicated with the outside of the ship body 3, and seawater and sludge in the sludge cabin are directly discharged to the outside of a ship board through gravity.

When the ship design stability is calculated, the bottom of the anchor chain cabin is communicated with the outside, but the bottom of the anchor chain cabin is still watertight with other cabins of the ship body 3, so that the ship stability is not influenced. When the ship is built, the jet pump and the piping system for sweeping the cabin can be saved, and the building cost is reduced. When the ship operates, the anchor chain is stacked on the structural grid platform when being folded, seawater and sludge brought by the folding of the anchor chain directly enter the sludge cabin in the shape of a funnel below through the opening on the structural grid platform and are immediately discharged to the outside through the pipe communicated with the outside, so that the seawater and the sludge do not need to be accumulated in the sludge cabin, a crew does not need to manually clean the sludge in the sludge cabin, the operation intensity of the crew is reduced, and the operation environment of the crew is improved. Establish mediation flange on blow off pipe 2 for blow off pipe 2 is opened mediation flange when blockked up by silt, inserts dredging tool mediation pipeline.

While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
