Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0040] Such as figure 1 As shown, the intelligent underwater bulldozer has a closed structure as shown in the figure. The hydraulic drive system and power electronic equipment of the intelligent underwater bulldozer are completely isolated from the external water environment through sealing materials, and the internal air flow is poor, so it cannot be forced to dissipate heat through the cooling fan; and When the intelligent underwater bulldozer is working, the heat dissipation requirements of the hydraulic oil in the hydraulic drive system are different from those of the onboard power electronic equipment. Therefore, the present invention designs a cooling system for the intelligent underwater bulldozer.

[0041] Such as figure 2 As shown, a cooling system of an intell...

Abstract

The invention provides an intelligent underwater bulldozer and a cooling system thereof, and belongs to the technical field of intelligent underwater bulldozer manufacturing. The cooling system comprises a hydraulic oil cooling system and a power electronic part cooling system, the hydraulic oil cooling system comprises a hydraulic oil tank, a power unit, a testing unit and a heat exchanger, and the testing unit is used for detecting the temperature of hydraulic oil and the instantaneous flow of the hydraulic oil in a cooling pipeline. The heat exchanger is used for heat exchange between the two cooling systems and the outside and heat exchange between the two cooling systems; and the power electronic part cooling system is provided with two parallel water paths, and the sequence of cooling liquid flowing through a heat dissipation part is arranged according to heat generated by a to-be-cooled part and the heat dissipation needs. A weak-demand cooling system of power electronic parts is used for assisting a strong-demand cooling system in heat dissipation, and the system has the advantages of being simple in structural design and obvious in heat dissipation effect.

Description

technical field [0001] The invention belongs to the technical field of intelligent underwater bulldozer manufacturing, and relates to an intelligent underwater bulldozer and a cooling system thereof. Background technique [0002] The intelligent underwater bulldozer is a fully sealed intelligent construction machinery for underwater operations. It supplies power to the motor drive system and other power electronic equipment through cables, making it free from the problem that traditional internal combustion engine-type amphibious operation machinery is difficult to complete underwater operations. It greatly improves its operation flexibility and work efficiency. The walking drive of the intelligent underwater bulldozer is driven by the drive motor to drive the hydraulic pump to work, and the hydraulic motor is used to output power, and the power is transmitted to the sprocket installed coaxially with the hydraulic motor to drive the crawler. The movement of the bulldozing b...
