Abstract

The utility model discloses a submersible discharge pipe, comprising a head end point station and a tail end point station. The head end point station is communicated with a dredge. The head end point station is connected with the tail end point station through a submersible flexible pipe. The head end point station comprises a box body floating on water; the box body is inside provided with a dredge pump and a motor driving the dredge pump to rotate; and an inlet of the dredge pump is communicated with the dredge. The tail end point station comprises a box body floating on water; the box body is inside provided with a dredge pump and a motor driving the dredge pump to rotate; and an inlet of the dredge pump is communicated with an outlet of the dredge pump in the head end point station through the submersible flexible pipe. The submersible discharge pipe is beneficial to cross-channel dredging working of the dredge in navigable rivers and has no influence on normal navigation.

Description

The diving mud pipe

Technical field

The utility model relates to a kind of corollary apparatus that is used for dredge boat, relates to a kind of mud that dredge boat is dug out, the diving mud pipe that sewage transport is gone out in particular.

Background technology

Fluviatic navigation channel is after using for a long time, and meeting is plug channel because of the generation of mud, influences the normal current of ship; And, just need use dredge boat in order to remove the mud in the rivers, mud is cleared; When dredge boat is released the mud of rivers bottom,, be impossible for a long time these mud are deposited aboard ship because receive the restriction of hull volume; If hull will be filled in a short period of time like this, can influence the work of dredge boat, therefore; These mud need be transported to the bank through other device, and the way of taking now is that a head-end station with its connection is set near the hull of dredge boat, on the coast or near the place, bank a tail point station is set; Connect through pipeline between two some stations, be equipped with hopper, tugboat and reclamation dredger etc. again, existing pipeline floats on the surface; So one is to influence other ship current in the navigation channel, and this has just limited the working time of dredge boat, and it is bigger to be exactly that pipeline receives the influence of stormy waves in addition; If weather condition is bad, dredge boat still can not be worked, even weather condition meets condition of work; Under the effect of stormy waves, the pipe loss of connection is very fast, and use cost is very high.

The utility model content

The purpose of the utility model is the weak point to prior art, and a kind of diving mud pipe is provided, and in the time of its work, the pipeline that is communicated with head-end station and tail point station sinks under water, and does not receive the influence of stormy waves, does not also influence the current of water surface ship.

The technological solution of the utility model is following

The diving mud pipe comprises head-end station and tail point station, and described head-end station and dredge boat are communicated with, and said head-end station and said tail point station are through the diving soft pipe connection.

Described diving mud pipe, said head-end station comprises the casing that is used at water float, the motor that dredge pump is installed in the said casing and drives said dredge pump rotation, the import of said dredge pump and said blowdown ship are communicated with.

Described diving mud pipe; Said tail point station comprises the casing that is used at water float; Dredge pump and the motor that drives said dredge pump rotation are installed in the said casing, and the blowdown delivery side of pump in the import of this dredge pump and the head-end station is through described diving soft pipe connection.

Described diving mud pipe, described head-end station comprise that also one is carried compressed-air actuated air compressor machine for said diving flexible pipe.

Described diving mud pipe is provided with the one way valve of the said diving flexible pipe of the unidirectional inflow of compressed air that an assurance comes out from air compressor machine between said air compressor machine and the said diving flexible pipe.

The utility model beneficial effect is:

1) economy: the diving flexible pipe that employing can be dived under water, make and dredge boat construction of can not stopping navigation in work improved the efficient of working, reduced construction cost;

2) equipment is simple: because the diving flexible pipe has been arranged, in work, the navigable river construction need not be equipped with hopper, tugboat and reclamation dredger etc., greatly reduces working cost;

3) construction is reliable: mud pipe in the past floats on the surface, and wind-engaging, wave influence are bigger, the work that then sinks under water of diving flexible pipe, and operating mode is than water surface work fashion; Significantly reduced the damage of wave, wind, prolonged spoil disposal pipeline application life mud delivery pipeline;

4) manoeuvrable: this novel features is less, and is divided into head-end station, tail point station and this several sections of diving flexible pipe, installs, dismantles all very simply, only needs dozens of minutes just can accomplish;

5) convenient transportation: the buoyancy aid at head-end station and tail point station all adopts the pin-connected panel body structure, is convenient to transportation.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is this novel work sketch map;

Fig. 2 is this new principle figure.

The specific embodiment

The following stated is merely the preferred embodiment of the utility model, is not that scope to the utility model limits.

Embodiment sees accompanying drawing 1,2, and accompanying drawing 1 is the work sketch map of this diving mud pipe; From accompanying drawing 1, can find out; It comprises head-end station 2 and tail point station 4, and described head-end station and dredge boat 1 are communicated with, and said head-end station and said tail point station are communicated with through diving flexible pipe 3.

See accompanying drawing 2, as can be seen from the figure, said head-end station comprises the casing 201 that is used at water float, the motor 203 that dredge pump 202 is installed in the said casing and drives said dredge pump rotation, and the import of said dredge pump and said blowdown ship are communicated with.

Said tail point station comprises the casing 401 that is used at water float; Dredge pump 402 and the motor 403 that drives said dredge pump rotation are installed in the said casing, and the blowdown delivery side of pump in the import of this dredge pump and the head-end station is through described diving soft pipe connection.The mud from dredge boat 1, extracted out of dredge pump 202, sewage are extracted out by dredge pump 402 after through the diving flexible pipe more like this, are discharged into the bank.

Described head-end station comprises that also one is carried compressed-air actuated air compressor machine 204 for said diving flexible pipe.

Be provided with the one way valve 205 of the said diving flexible pipe of the unidirectional inflow of compressed air that an assurance comes out from air compressor machine between said air compressor machine and the said diving flexible pipe.

Operating principle: have the floating function of diving in order to realize diving flexible pipe waterborne; On the diving flexible pipe, be provided with head-end station and tail point station, head-end station and tail point station all can float on the surface, and start the dredge pump that is located on head-end station and the tail point station; Be the mixture by water and mud this time in the diving flexible pipe; The diving flexible pipe can sink to the river bed when the quantity of water and mud acquires a certain degree, and during spoil disposal, dredge boat just can be through the defeated mud of the mud pipe that dives into the water; When guaranteeing the dredge boat construction like this, can guarantee the navigation in river course.

When construction finishes or need rise when floating midway; The air compressor machine that starts on the head-end station is inflated in the diving flexible pipe, forces the water in the pipeline to be discharged from the tail point station, charges into along with compressed-air actuated; The diving flexible pipe is emerged by head end and tail end piecemeal, accomplishes diving and floating of diving flexible pipe between two stations.
