Hydraulic system as well as brake method and boosting method thereof

Abstract

The invention discloses a method for braking and boosting by the characteristics of a hydraulic system. The hydraulic system comprises a hydraulic motor, an oil inlet path, an oil returning path, a hydraulic pump, a first solenoid valve, a second solenoid valve, a third solenoid valve and an energy accumulator, wherein the oil inlet path is connected with a first cavity, and the oil returning path is connected with a second cavity; the hydraulic pump charges oil into the hydraulic motor via the oil inlet path; the first solenoid valve controls the oil inlet path to be communicated with the hydraulic pump; the oil inlet path is connected to the first cavity by the third solenoid valve; and the energy accumulator is connected to the first cavity by the third solenoid valve and is connected to the second cavity by the second solenoid valve. In a hydraulic winch adopting the hydraulic system, a winding drum can be braked and buffered in the cable unreeling process, the equipment maintenance cost is lowered, the efficiency on measuring a vertical section is improved, and the A cavity of the hydraulic motor can be subjected to pressure supplementation when a falling body falls so as to assist a cable unreeling process in overcoming the rotational inertia of the winding drum, thereby quickening the falling speed of the falling body.

Description

technical field [0001] The invention relates to the technical field of water body measurement, in particular to a hydraulic system, a braking method and a boosting method thereof. Background technique [0002] At present, with the rapid progress of science and technology, the development, utilization and protection of human water resources (including oceans, rivers and lakes) are also developing by leaps and bounds. To develop and utilize water resources, we must first understand the water body, and hydrographic measurement of the water body is a way to understand the water body. [0003] For example, in physical oceanography, as the temperature and salinity of water layers at different depths change, the speed of sound also changes. Obtaining the above water body parameters in a specific sea area can be used for ocean mapping such as sonar velocity measurement and ranging; and For example, measuring water body parameters such as temperature and salinity (salt content) of s...

AI Technical Summary

Problems solved by technology

[0014] The problem solved by the present invention is that when the existing electric winch releases the falling body, the friction plate of the soft brake is seriously worn out during frequent use, resulting in frequent replacement

[0015] Another problem solved by the present invention is that when the existing electric winch releases the falling body, it is difficult to accelerate to a stable falling speed in a short time
