Abstract

The utility model relates to a submarine mud cleaning device driven by engine drawing ship, comprising a steel harrow head with harrow teeth below, a harrow pole and a steel wire cable power input for connecting the engine drawing ship. One end of the harrow pole is positioned together and connected with the steel wire cable power input. The other end of the harrow pole is arranged symmetrically and connected with a harrow head. A vibration component is arranged in the harrow head. A power cable connected with the vibrating component by the steel wire cable power input is arranged in the harrow pole. During operation, according to the depth of water, the harrow head is put deeply into the submarine mud and sand by the steel wire cable roller, after turning on the power, the submarine cleaning operation is performed by the harrow repeatedly driven by the engine drawing ship, realizing the purpose of dredging river or cleaning the accumulated mud and sand up in the reservoir. The model has the advantages of brief structure, convenient operation, low cost and good effect on cleaning silt. The model is applicable to plain river bed and all kinds of big, middle and small reservoir to clean the accumulated mud and sand on a big scale.

Description

The towed desilting rake of boat-carrying

Affiliated technical field

The utility model content belongs to the water engineering machinery technical field, relates to a kind of Accrete clearing device that is suitable for removing shoal materials in river course, Plain and all kinds of large, medium and small type reservoir.

Background technology

The plains region is because the river course is easy to pile up silt gently, thereby how effectively to remove silt become a great problem that the particularly all kinds of large, medium and small type reservoirs in river course, Plain must solve in the retaining process.At present this area adopts giant formula dredger to remove mud river course or storehouse in usually, but its correspondingly in actual applications exist complex structure, operation is inconvenient, cost is high and to below the water surface than problems such as depths shoal materials scavenging action are limited.

The utility model content

The purpose of this utility model is the problem that prior art exists is solved, and then provides a kind of simple and practical, easy to operate, with low cost and towed desilting of boat-carrying that have an extensive removing silt alluvial function to harrow.

The technical solution that adopts is so for achieving the above object: the towed desilting rake of the boat-carrying that is provided be removed the device of shoal materials under water for a kind of can the drive by the motor traction ship, it has the steel rake face that a pair is divided into rake teeth, at least two raking arms and one are used for the wirerope power interface that is connected with the motor traction ship, raking arm is made by steel pipe, the one end converges and is connected on the wirerope power interface, the discrete symmetry of the other end is connected on the rake face, in the rake face, be provided with vibrating elements, in raking arm, be provided with power line with vibrating elements and wirerope power interface UNICOM.During work, will harrow the face rake teeth according to the water surface depth and needs by the wirerope capstan winch and place silt under water deeply, connect power supply after, the desilting rake under the motor traction ship drives in the underwater the touring dredging operation that carries out, realize removing the purpose that silt deposits in river course or the storehouse.

Compared with prior art, advantage such as the utlity model has and dredging effect is good rational in infrastructure, easy to operate, with low cost, product especially is being used for fixedly major river bed and remove all kinds of large, medium and small type reservoirs particularly the silt alluvial effect of great rivers estuary silt and large and medium-sized reservoir afterbody is more remarkable of desilting sand surfing reparation in rainy season.

Fig. 2 is a ramp structure schematic diagram embodiment illustrated in fig. 1.

The specific embodiment

Referring to accompanying drawing, the towed desilting rake of boat-carrying described in the utility model is made of steel rake face 1, rake teeth 2, raking arm 3 and wirerope power interface 4.Rake face 1, rake teeth 2, raking arm 3 select for use hardness and the satisfactory high-quality steel of toughness to make according to building trade vibrating head principle, and weight generally should be more than 100 kilograms.Raking arm 3 is made by the steel pipe more than two, one end of each steel pipe converges and is connected on the wirerope power interface 4, and the other end is the discrete symmetry of fan-shaped and is connected on the rake face 1, and the angle between raking arm 3 and the rake face 1 is 90 °, rake teeth 2 should be harrowed face 1 relatively to raking arm 3 direction bendings, to penetrate with among the silt.Be provided with vibrating elements in the rake face 1, in raking arm 3 steel pipes, then be provided with power line with vibrating elements and wirerope power interface 4 UNICOMs.Wirerope power interface 4 can be the interface of cassette, cellular type or other known manner.In actual the use, changeable by winch control according to the water surface depth and needs with the wirerope that the rake body is connected, size, power and the wirerope of traction hull should be harrowed with the vibration desilting and be complementary, during work as not adopting mode of vibration then to need not to connect power supply.In addition, the utility model also can be designed to the structure of non-vibration formula, its design form is that raking arm 3 is made by steel pipe that does not contain power line in it or solid rod iron, one end of each raking arm converges and is connected on the wirerope interface 4, the discrete symmetry of the other end is connected on the rake face 1, vibrating elements also no longer is set in the rake face 1, and the remainder except that above-mentioned is all identical with vibration desilting rake.
