Abstract

The utility model discloses a square mud door seal structure, and belongs to the technical field of ship machinery. The square mud door seal structure comprises a mud door; two sides of the mud door are provided with hinge supports; the frame side of the hinge side is a mud cabin door sealed by a seal ring; the mud cabin door is of a box-type panel structure; and a pin shaft is arranged below the panel end part which is additionally provided with a mud guide plate. According to the utility model, a panel of a frame of the hinge side is additionally provided with the mud guide plate, and thus when the mud door is opened, all mud stones slide downward without residual on the frame; and when the mud door is closed, a stone clamping phenomenon does not exists, the mud door seal is ensured, and the economic benefit is improved.

Description

A kind of square mud door sealing structure

Technical field

The utility model relates to the ship machinery technical field, particularly the square mud door sealing structure of a kind of dredge boat.

Background technology

Dredge boat is a kind of ship machinery of extensive use, is mainly used in clearing up water-bed mud and foreign material.Can guarantee the depth of water, be conducive to the normal navigation of ship.The square mud door 1 of dredge boat is opposite opened, and as shown in Figure 1, both sides are by hinge support.The spoil hopper door of dredge boat is the box-shaped slabbed construction, with rubber strip 2 sealings, under the flat board bearing pin 3 is arranged all around.When square mud door is opened, can be at the residual mudstone of the frame of hinge side, residual mudstone and mud doorframe produce extruding when Ni Men closes, and damage hull mud doorframe, the impact sealing.

The utility model content

There is card stone in order to solve the square mud door sealing structure of present dredge boat, damages hull mud doorframe, the problem of impact sealing, the utility model embodiment provides a kind of square mud door sealing structure.Described technical scheme is as follows:

A kind of square mud door sealing structure comprises the mud door, the mud door, there is hinge support on described Ni Men both sides, and described hinge side border side is the spoil hopper door of sealing ring sealing, and described spoil hopper door is the box-shaped slabbed construction, described dull and stereotyped end has bearing pin, and wherein, described dull and stereotyped end is set up and is connected with mud guiding plate.

Preferably, described mud guiding plate is circular arc.

Preferably, described mud guiding plate and described plate welding.

Compared with prior art, the square mud door sealing structure that technique scheme provides has the following advantages: by setting up mud guiding plate at the flat board of hinge side frame, so that mudstone all glides when Ni Men opens, do not remain on the frame, when closing, the mud door do not have card stone phenomenon, guarantee the sealing of mud door, improved economic benefit.

Description of drawings

In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is prior art mud door sealing structure schematic diagram;

Fig. 2 is the mud door sealing structure schematic diagram that provides among the utility model embodiment;

The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.

As shown in Figure 2, the utility model embodiment provides a kind of mud door sealing structure, the square mud door 1 that comprises opposite opened, there is hinge support on mud door 1 both sides, the hinge side frame is provided with the spoil hopper door of sealing ring 2 sealings, the spoil hopper door is dull and stereotyped 5 structures of box-shaped, also is provided with bearing pin 3 under dull and stereotyped 5 ends, sets up in flat board 5 ends of mud door hinge side and is connected with circular arc mud guiding plate 4.This mud guiding plate 4 and dull and stereotyped 2 welds together.Mud guiding plate 4 contacts with sealing ring 2 when mud door 1 opens to limit position, and mudstone 1 all glides through circular arc mud guiding plate 4 and do not remain on the hinge frame.Like this, do not have card stone phenomenon when mud door 1 is closed, mud door 1 opens and closes freely, has also guaranteed the sealing of mud door, and preferably effect is arranged, and has greatly improved economic benefit.

The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
