Problems solved by technology

Its disadvantages are as follows: firstly, a long and very expensive deep-water cable is required to provide power on board, and the power provided by the battery pack is not only limited in power, not durable, but also has problems such as poor low-temperature discharge performance; in addition, the above two methods are both It can only provide electric power. To convert electric power into hydraulic power, it is necessary to set up corresponding equipment such as electric motors and hydraulic pumps.
Therefore, there are defects such as large energy consumption, large volume and heavy weight in the prior art

Embodiment 1

[0012] like figure 1 As shown, 1 in the figure is a pressure-resistant container, 2 and 7 are high-speed one-way valves, 3 is a hydraulic cylinder, 4 and 6 are high-speed switching valves, and 5 is a seawater pressure flow control valve block. Among them, the seawater pressure flow control valve block 5 is arranged on the top of the entire hydraulic system, and the seawater pressure flow control valve block 5 communicates with the hydraulic cylinder 3 through the high-speed switching valves 4 and 6: the high-speed switching valves 4 and 6 are respectively set on the top of the hydraulic cylinder 3 , and communicate with the cavities on the left and right sides of the hydraulic cylinder 3; the hydraulic cylinder 3 communicates with the pressure-resistant container 1 arranged at the bottom of the hydraulic drive system through the high-speed check valves 2 and 7: the high-speed check valves 2 and 7 are respectively set It is at the bottom of the hydraulic cylinder 3 and communic...

Embodiment 2

[0018] like figure 2 As shown, the seawater pressure flow control valve block 5 communicates with the hydraulic motor 8 through the high-speed switch valves 4 and 6 , and the hydraulic motor communicates with the pressure-resistant container 1 through the high-speed one-way valves 2 and 7 . Among them, the high-speed on-off valve 4 and the high-speed one-way valve 7 are arranged on one side of the hydraulic motor 8, and communicate with a pair of water inlet and outlet ports on the hydraulic motor 8, and the high-speed on-off valve 6 and the high-speed one-way valve 2 are correspondingly arranged on the hydraulic motor 8. The other side of the hydraulic motor 8 communicates with another pair of water inlet and outlet. The input ends of the high-speed switching valves 4 and 6 are connected to the seawater pressure flow control valve block 5, and the output ends are respectively connected to the two water inlets of the hydraulic motor 8; the input ends of the high-speed check v...

Embodiment 3

[0024] In Embodiment 2, a generator set can be installed coaxially with the hydraulic motor, and the hydraulic motor can be driven to generate electricity while utilizing the pressure of deep sea water to drive the coaxial generator set to generate power in deep sea. The electrical energy that the hydraulic drive system can provide is related to the volume of the pressure vessel, the larger the volume, the greater the electrical energy it can provide. Therefore, the volume of the pressure vessel can be designed according to the actual deep sea operation time. The hydraulic drive system can provide sufficient power resources for the short-term work of the deep-sea resource development operation device, or the deep-sea resource detection device that stays on the seabed for a long time.

[0025] Others are the same as embodiment 2.

Abstract

The invention relates to a hydraulic driving system, in detail a water pressure hydraulic driving system in deep sea. Great energy dissipation, bit cubage and heavy weight in prior hydraulic driving system are conquered. The invention comprises hydraulic acting device, pressure resistant container, high-speed switch valve, high-speed one-way valve and sea water pressure control valve for flow. Sea water pressure control valve for flow is connected with hydraulic acting device by two high-speed switch valves, which is connected with pressure resistant container by two high-speed one-way valves, and hydraulic acting device is hydraulic cylinder or motor. By the hydraulic difference between deep sea circumstance and pressure resistant container, under the control of sea water pressure control valve for flow, hydraulic acting device is driven to work through controlling high-speed switch and one-way valves so that various works in deep sea are realized. It is provided with small cubage, light weight and low energy dissipation.

Description

technical field [0001] The invention relates to a hydraulic drive system, in particular to a deep sea water pressure type hydraulic drive system. Background technique [0002] In the prior art, deep-sea operations generally complete various tasks by setting hydraulic stations in deep-sea operation devices, wherein the hydraulic stations include hydraulic oil tanks, hydraulic pumps, hydraulic actuators, etc., and are powered or powered by the ship when working. Powered by an underwater battery pack, the motor is driven to operate, and the motor drives the hydraulic pump to form high-pressure oil, which drives the hydraulic actuator to perform various deep-sea operations. Its disadvantages are as follows: firstly, a long and very expensive deep-water cable is required to provide power on board, and the power provided by the battery pack is not only limited in power, not durable, but also has problems such as poor low-temperature discharge performance; in addition, the above tw...
