Embodiment Construction

[0035] The present invention will be further described in detail below in combination with specific embodiments.

[0036] Such as figure 1 , figure 2 and image 3 As shown, a dynamic positioning jet jetting type trenching machine of the present invention includes a main frame, and the main frame is composed of a front main beam 2 and a rear main beam 5 and is arranged around the front main beam 2 and the rear main beam 5. The skids at both ends constitute, the front sub-beam 9, the middle sub-beam 8 and the tail sub-beam 7, which are all fixed with the skids at both ends, are arranged between the front main beam 2 and the rear main beam 5, that is, the main frame includes There are five beams, all of which are connected to the skids at the left and right ends with bolts through the round flange at the lower part. All are fixed with a thruster 13 in place, and the power supply is respectively transmitted underwater by the low-voltage generator set 62 on board by the power c...

Abstract

The invention discloses a power positioning jet-flow spraying type ditcher, which comprises sliding pries arranged at the left end and the right end of a framework, wherein the sliding pries are floating barrel type sliding pries of which the cross sections are in duck egg shapes; two high-pressure submersible pumps which are symmetric with each other in the transverse direction are arranged on the top of the framework; two high-pressure water-jet guide frames which are symmetric with each other in the transverse direction and connected with the high-pressure submersible pumps on the same side are connected to the front lower side of the frame; the lower front parts of the high-pressure water-jet guide frames are provided with a plurality of high-pressure water nozzles and a plurality of rotary nylon rollers; two sludge suction and drainage pumps which are symmetric with each other in the transverse direction are arranged above the framework; two sludge suction and drainage guide frames which are symmetric with each other in the transverse direction are arranged on the rear lower side of the framework; the lower parts of the sludge suction and drainage guide frames are provided with a plurality of rotary nylon rollers and a plurality of sludge suction and drainage channels which are connected with the sludge suction and drainage pumps on the same side; and both the sludge suction and drainage pumps are connected with a sludge drainage pipe respectively. The ditcher can dive into the water by 250 meters and is high in power, efficiency and reliability, so submarine construction for ditching deep trenches less than or more than 2 meters can be realized safely; and the ditcher has functions of sucking and draining sludge.

Description

technical field [0001] The invention relates to trenching operation equipment for various underwater pipe diameters of oil transportation, gas transportation, water supply and drainage pipelines, in particular to a dynamic positioning jet jet flushing type trenching machine, which can economically, efficiently and environmentally friendly complete underwater trenching operations. Various deep trench digging operations. Background technique [0002] At present, in the field of underwater trenching operations, contact trenching machines are mostly used, that is, the trenching equipment is directly mounted on the submarine pipeline by the guide legs for trenching operations. The structural types of the equipment basically include twisting suction, twisting jet Suction type and suspension jet type have their own advantages. But the main problems are: low equipment power, low efficiency, high cost and high negative pressure on pipelines, especially when digging deep trenches of ...
