Abstract
The utility model relates to a mud suction head of an underwater dredger, which comprises a float tank, wherein a water charging and draining hole is formed at the lower part of the float tank; the water charging and draining hole is closed by a screw plug. A mud suction pipe passes through the middle part of the float tank, a trumpet-shaped mud suction swallow opening is formed at the lower end of the mud suction pipe. High-pressure water faucets of which the inward inclined angles are adjustable are installed on the undersurface of the float tank. The high-pressure water faucets are distributed around the mud suction swallow opening; the high-pressure water faucets are communicated with high-pressure water pipes. The utility model can effectively control the concentration of sludge, overcome the phenomenon of clogging and realize continuous work to improve work efficiency. The mud suction head of an underwater dredger can normally work in areas without power. The utility model has the advantages of low manufacturing cost and convenient operation. The mud suction head of an underwater dredger can work in brooks, gutters, ponds and ports.
Description
The utility model relates to the soil-suction head of dredging operation machinery, particularly underwater silt remover under water.
Existing machines for mud clearage comprises strand suction formula, grab type, bucket dredger etc., only is applicable to the engineering of desilting and dredging in large-scale river course, and unit equipment is huge, involves great expense, and can't enter the river road and carry out dredging operation under water.Small-sized underwater silt remover also has multiple, and a kind of way commonly used is to adopt slush pump to dash in a special seal closure to inhale, and inhales a pitting but once can only dash, and can only discontinuous operation, and dredging effect is very undesirable; Also there is the submersible pump of employing to inhale silt under water, but dangerous, can not lack the area construction at power supply again.At present, aspect the research of small-sized submarine mechanical, though through painstaking efforts, it is unresolved such as foreign material how obstruction, the construction operation in non-transformer area, the control of concentration of hydraulic mixture, the hardboard soil layer of pump and pipeline to be dredged problem such as dark.
The purpose of this utility model is to provide a kind of can be implemented under water continuously towards suction, desilting, dredge the soil-suction head of the small-sized underwater silt remover of dark operation.
Solution of the present utility model is: contain a buoyancy tank, the buoyancy tank bottom is provided with fills drain hole, it is airtight by plug screw to fill drain hole, dredging tube passes through from the buoyancy tank middle part, the lower end of dredging tube is provided with and is trumpet-shaped suction mud and gulps down mouth, at the buoyancy tank soffit the adjustable high pressure water nozzle of inclined angle is housed, the high pressure water nozzle be distributed in inhale that mud gulps down mouthful around, high pressure water nozzle and high-pressure water pipe interlink.
Adopt the utility model can control the concentration of mud effectively, overcome the clogging in the desilting engineering under water, can realize working continuously, improved work efficiency, but also normal construction of areas without electricity, and low cost of manufacture, easy to operate, all can construct in river, ditch, fish pond and harbour.
Accompanying drawing is an embodiment of the present utility model.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the upward view of the utility model embodiment;
Fig. 3 is the left view of the utility model embodiment;
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Buoyancy tank 1 is designed to the interlayer seal case of indent, profile is shape, adopting flow is 100 cubic metres of self-priming dredge pumps of no obstruction type hourly, and buoyancy tank is 0.4 square metre to the area that effectively shrouds of mud, can reduce mud that water under high pressure dashed effectively and spread to river is central.The lower housing portion of buoyancy tank 1 is provided with two and fills drain hole, and it is airtight by plug screw 2 respectively to fill drain hole, realizes regulating with the method for filling draining the buoyancy of buoyancy tank, with the grounding pressure of control the utility model complete machine.The lower end of dredging tube 3 is equipped with suction mud and is gulped down mouth 4, suction mud gulps down mouth 4 and is horn-like, dredging tube 3 passes through from buoyancy tank 1 middle part, and flexibly connect with buoyancy tank 1, make suction mud gulp down mouth 4 and can regulate according to the optium concentration of mud layer, reach optimal effectiveness to guarantee the concentration of hydraulic mixture and the flow that suck with the relative altitude of buoyancy tank 1 bottom surface.Dredging tube 3 upper ends link to each other with the import of the self-priming dredge pump of no obstruction type, on buoyancy tank 1 soffit around suction mud gulps down mouth 4 10 high pressure water nozzles 5 are housed, high pressure water nozzle 5 flexibly connects with high-pressure water pipe 6, high-pressure water pipe 6 links to each other with high-pressure pump, the discharge pressure of high pressure water nozzle 5 is regulated by high-pressure pump, dash the requirement of inhaling different mud to adapt to, the inclined angle of high pressure water nozzle 5 is adjustable between 5 °-10 °.
