As shown in fig. 4, the first pipeline 15.1 and the second pipeline 15.2 are provided with a hand pump 18 and a flow meter 19, and the first pipeline 15.1 and the second pipeline 15.2 are respectively connected with one end of the on-gas tank 16 and one end of the off-gas tank 17.

As shown in fig. 5, the gas-liquid linkage control system comprises a central processing unit, a wireless module and an electronic control module, wherein the central processing unit is electrically connected with the wireless module and the electronic control module, the wireless module is connected with an angle sensor 8 and a flow meter 19, the electronic control module drives an electromagnetic valve 21 and a direct-current servo motor 14, and the direct-current servo motor 14 drives an adjusting device 13 to work.
The working process is as follows: hydraulic oil is filled in the open gas liquid tank 16 and the closed gas liquid tank 17, when the gas-liquid linkage system does not work, the hydraulic oil accounts for half of the volume of the open gas liquid tank 16 and the closed gas liquid tank 17, when the gas-liquid linkage system works, the central processing unit orders the electromagnetic valve 21 connected with the open gas liquid tank 16 to open, an electromagnetic valve 21 connected with a gas closing tank 17 is closed, natural gas or nitrogen is introduced into an air inlet pipeline 20 to enter a gas opening tank 16, a large amount of gas is gushed from the upper portion of the gas opening tank 16, hydraulic oil at the lower portion of the gas opening tank 16 flows downwards through a first pipeline 15.1 under the pressure, the hydraulic oil is measured by a flow meter 19 and feeds a flow value back to a central processing unit, the hydraulic oil flows into a first cavity 1.1 through a hand pump 18, the first cavity 1.1 is communicated with a third cavity 1.3 through a first flow channel 3.1, and then the third cavity 1.3 is also filled with the hydraulic oil and keeps balance with the air pressure of the first cavity 1.1, so that the mechanical loss of rotor blades is prevented. The governor valve 23 is adjusted to regulate the flow rate therethrough, reducing pressure loss and reducing heating of the hydraulic oil.
The pressure in the first cavity 1.1 and the third cavity 1.3 is large, the pressure in the second cavity 1.2 and the fourth cavity 1.4 is small, and the pressure difference enables the rotor 5 to drive the rotor blade 5.1 to rotate anticlockwise to compress the volumes of the second cavity 1.2 and the fourth cavity 1.4, so that the pressure in the second cavity 1.2 and the fourth cavity 1.4 is increased, hydraulic oil originally in the second pipeline 15.2 is pressed into the gas-closing liquid tank 17 through a hand pump, and the hydraulic oil is measured when flowing through the flowmeter 19 and feeds a flow value back to the central processing unit. When the rotor blade 5.1 is rotated to a given position, the control action is ended and the remaining linear pressure can be released to the atmosphere.
When the rotation angle of the rotor 5 needs to be accurately controlled, the angle sensor 8 feeds back the angle information to the central processing unit through the wireless module, and when the angle reaches a preset value, the central processing unit commands the electric control module to drive the electromagnetic valve 21 connected with the gas-opening liquid tank 16 to be closed, and gas inlet is stopped. Considering that the intake pressure is large, there is a delay in control, and an adjustment device may be used for a minute angle adjustment. The central processing unit orders the electronic control module to drive the direct current servo motor 14 to drive the adjusting device 13 to work, the adjusting device 13 is clamped outside the large gear 12 and the small gear 10, the large gear 12 is firstly adjusted to drive the second screw 11 to push the stop block 6 to carry out coarse adjustment, the small gear 10 is adjusted to drive the first screw 9 to carry out fine adjustment, the angle sensor 8 feeds back the angle size of the central processing unit in real time, the static friction force is considered to exist when the adjustment is just started, the resistance is large, and therefore the angle sensor 8 is connected with the spring 7 to avoid the excessive adjustment. After working for a period of time, because the air tightness problem can cause the situations of oil leakage and the like, the flow rate situation in a period of time can be measured through the flow meters of the first pipeline 15.1 and the second pipeline 15.2, and if the flow rates in a period of time of the first pipeline 15.1 and the second pipeline 15.2 are not balanced, the situation that the gas liquid tank 16 is opened or the gas liquid tank 17 is closed is required to be overhauled in time.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
