Problems solved by technology

When the above scheme is adopted, the transmission efficiency of the entire underwater mud pump device is low, and due to the heavy weight of the equipment, the cost of the bridge frame for installing the carrier of the underwater mud pump device is increased to meet the needs of strength and rigidity, so that related equipment And the parameters of the ship will increase, which will eventually lead to an increase in the cost of ship construction and affect the economic benefits of the project

Embodiment Construction

[0007] Below in conjunction with all accompanying drawings the present invention will be further described, and preferred embodiment of the present invention is: see appended figure 1 , The underwater mud pump device described in this embodiment includes a mud pump 1, a waterproof motor 2, and an elastic coupling 3, wherein the waterproof motor 2 is installed on the mud suction frame 4, and is connected to one end of the elastic coupling 3 , the other end of the elastic coupling 3 is connected to the mud pump 1 installed on the mud suction frame 4 to provide power for the mud pump 1; the mud pump 1 is connected to the cutting device 6 through the mud suction pipe 5. After adopting the above solution, the waterproof motor 2 directly drives the underwater mud pump 1 through the elastic coupling 3 . Compared with the traditional submerged mud pump device, the reduction gearbox and transmission shafting are reduced. This scheme not only saves the expensive frequency conversion dr...

Abstract

The invention provides an underwater mud pump device for suction dredging ships, which includes a mud pump, a waterproof motor, and an elastic coupling, wherein the waterproof motor is installed on the mud suction frame, and is connected with the mud pump. One end of the elastic coupling is connected, and the other end of the elastic coupling is connected with the mud pump installed on the mud suction frame to provide power for the mud pump; the mud pump is connected with the cutting device through the mud suction pipe. After adopting the above scheme, the present invention not only saves the expensive frequency conversion drive system and saves investment, but also greatly improves the transmission efficiency and stability during work due to the shortened transmission distance. Especially obvious.

Description

technical field [0001] The invention relates to the technical field of underwater dredging, in particular to an underwater mud pump device for a suction dredging ship. Background technique [0002] Suction-lift dredging ships are widely used in the treatment of inland rivers and sea channels and port maintenance. When the dredging depth is large, underwater dredging technology is generally used to increase the mud concentration. That is to say, the prime mover is installed above the waterline, and the mud pump is driven through a long transmission shaft; since the performance characteristics of the mud pump, the displacement and the pressure head correspond to the speed of the mud pump, in order to reasonably match the work between the motor and the mud pump, According to the working conditions of the actual ship, it is necessary to calculate according to the dredging theory of the dredger to determine the displacement, pressure head and speed of the underwater dredge pump, ...
