Problems solved by technology

In fact, the heat dissipation demand of power electronic components is relatively small, while the heat dissipation demand of hydraulic oil is large. How to use the cooling system with weak demand to assist the strong cooling system to dissipate heat to optimize the cooling effect. At this stage, the cooling structure with this feature is in the water It is difficult to reflect on the unmanned bulldozer

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] like 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] like figure 2 As shown, a cooling system of an intelligent ...

Abstract

The invention provides an intelligent underwater bulldozer and a cooling system thereof, belonging to the technical field of intelligent underwater bulldozer manufacturing. The cooling system includes a hydraulic oil cooling system and a power electronic component cooling system. The hydraulic oil cooling system includes a hydraulic oil tank, a power unit, a test unit and a heat exchanger. The test unit is used to detect the temperature of the hydraulic oil and the hydraulic pressure in the cooling pipeline. The instantaneous flow of oil, the heat exchanger is used for heat exchange between the two cooling systems and the outside world and between the two cooling systems; the power electronic component cooling system has two parallel waterways, which are adjusted according to the heat generated by the components to be cooled and the heat dissipation requirements The order in which the coolant flows through the cooling components is arranged. The invention utilizes the weak-demand cooling system of power electronic components to assist the strong-demand cooling system to dissipate heat, and has the advantages of simple structural design and obvious 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...
