Abstract

The utility model discloses a slide-type underwater slit cleaner pulled by a workboat. The slide-type underwater slit cleaner comprises a bracket formed by a pair of slide-type walking boards (53). A flat plate (55) is mounted at the upper part of the bracket; a through hole for the installation of a mud suction pipe (3) is formed on the flat plate; and a connecting head (2) pulled by the workboat is arranged at the front end of the bracket. Since the area of the flat plate is relatively large, the slit cleaner can be directly supported to float on the interface of a soft silt layer and a clean water layer; just soft slits are sucked during the construction, and the hard soil layer is not damaged, which facilitates the ecological and environmental protection; the proportion of water of sucked slits is remarkably reduced, so that the construction efficiency is improved; moreover, the structure is simple, and the bracket formed by slide-type walking boards is adopted, thereby facilitating the sliding on the hard earth layer along the river bottom with small resistance, facilitating the traction power of the workboat, and reducing the costs of the equipment production and the construction.

Description

Skid formula underwater silt remover

Technical field

The utility model belongs to environmental technology field, particularly a kind of dredger by the operation ship traction of removing river course, lake, reservoir bottom surface mud.

Background technology

Natural waters such as the river of China, river, lake, storehouse and drinking water source ground water quality go from bad to worse, and demand urgently administering.Traditional desilting has environmental protection and two kinds of purposes of engineering usually, the environmental protection class is in order to remove water-bed soft mud, to reduce turbidity, increase water quality, common suction nozzle with suction pipe sinks under water and by dredge pump mud is drawn onto on the operation ship, this mode efficient is low, and the moisture that drinks up is more than mud, and construction cost is too high; Engineering is in order to deepen the depth of water, to open up deep stream, being furnished with excavator, and is bulky, and the cost height also can destroy water-bed ecology, causes water body to lose self-purification capacity.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of improving the skid formula underwater silt remover by operation ship traction that water quality is purpose, and the efficiency of construction height, and cost is low.

The technical solution of the utility model is:

A kind of skid formula underwater silt remover by the operation ship traction is characterized in that the support that a secondary skid shape walking plate constitutes, and a flat board is installed on support top, and this flat board has for the through hole that dredging tube is installed, and the support front end is equipped with the connector that draws for by operation ship.

Described flat board and the height of sled at the end are 30～100mm.

Install for the pipe that is connected with dredging tube on the described dull and stereotyped through hole and connect.

The front end upstream face of described skid shape walking plate is made the sharp side.

Because general river bed is made of the soft mud that precipitates on the hardpan, requirement according to ecological dredging, the utility model is only to soft mud desilting, can not destroy under the basis of ecological environment under water, and the soft mud layer that the bottom is contained a large amount of pollutants is removed.The utlity model has following substantive distinguishing features:

Because platen area is bigger, directly frame floats over soft mud and clear water layer interface, only sucts soft mud during construction and does not destroy the hard soil layer, helps ecology and environmental protection; The moisture ratio significantly reduces in the silt slurry that drinks up, improved efficiency of construction, and it is simple in structure, the support that has adopted skid shape walking plate to constitute, resistance is little by sliding on the hardpan to be easy to along the river the end, helps reducing the traction power of operation ship, reduce device fabrication and construction cost, be specially adapted to the purification of water quality engineering of natural water bodies such as the vast river course of China, lake, reservoir.

The specific embodiment

With reference to accompanying drawing, the support that dredger 5 is made of a secondary skid shape walking plate 53, walking plate 53 bearings are on hard soil layer C.Flat board 55 is installed by angle connector 56 screws in support top, because the degree of depth of soft mud B is generally about 0.5 meter, the dull and stereotyped and design height of sled at the end is 30～100mm; About 8 square metres of dull and stereotyped 55 areas to produce bigger frame buoyancy at soft mud, separate soft mud B and clear water layer A, can only effectively reduce the suction to clear water to soft mud suction.Dull and stereotyped 55 have for the through hole that dredging tube 3 is installed, and install for the pipe that is connected with dredging tube 3 on the through hole and connect 54, and the support front end is equipped with the connector 52 that draws for by operation ship 1, is connected with operation ship 1 by cable wire 4.

For the resistance that moves ahead that reduces to draw, the front end upstream face of skid shape walking plate 53 can be made into sharp side or cambered surface.

Dredge pump 2 is housed on the operation ship 1, and such as sand suction pump or slush pump, its import 22 connects 54 by the pipe that dredging tube 3 connects, and outlet 21 is with in the mud input ship that comes on the pump.

Claims

1, a kind of skid formula underwater silt remover, it is characterized in that the support that a secondary skid shape walking plate (53) constitutes, a flat board (55) is installed on support top, and this flat board has for the through hole that dredging tube (3) is installed, and the support front end is equipped with the connector (52) that draws for by operation ship.

2,, it is characterized in that flat board (55) and the height of sled at the end are 30～100mm according to the described skid formula of claim 1 underwater silt remover.

3,, it is characterized in that installing on the dull and stereotyped through hole pipe that supplies to be connected and connect (54) with dredging tube according to the described skid formula of claim 1 underwater silt remover.

4,, it is characterized in that the front end upstream face of skid shape walking plate (53) is made the sharp side according to the described skid formula of claim 1 underwater silt remover.
