Abstract

Claims (32)

1 . A system, comprising:

a turbine engine;

an exhaust subsystem of the turbine engine configurable into an operational state and an idle state distinct from the operational state; and

a load drivable by the turbine engine from an exhaust end of the turbine engine via at least one driving shaft that passes through walls of an exhaust duct of the exhaust subsystem, the exhaust duct being connected to an exhaust side of the turbine engine and being separate from the turbine engine;

wherein the turbine engine, the exhaust subsystem, and the load are installed on a common base.

2 . The system of claim 1 , wherein the exhaust subsystem is disposed between the exhaust end of the turbine engine and the load.

3 . The system of claim 2 , wherein the exhaust subsystem comprises the exhaust duct and an exhaust silencer.

4 . The system of claim 3 , wherein a first end of the exhaust duct is coupled to the exhaust end of the turbine engine, and is configured to guide an output exhaust of the turbine engine from horizontal to upward through a second end of the exhaust duct.

5 . The system of claim 4 , wherein the exhaust silencer is coupled to the second end of the exhaust duct via a pivotal connection.

6 . The system of claim 5 , further comprising a turnover mechanism configured to drive the exhaust silencer to rotate around the pivotal connection.

7 . The system of claim 6 , wherein the turnover mechanism is configured to:

drive the exhaust silencer to an operational position in the operational state such that the exhaust silencer conformably couples to the second end of the exhaust duct to guide the output exhaust of the turbine engine through an internal passage of the exhaust silencer upward; and

drive the exhaust silencer to an idle position in the idle state such that the internal passage is decoupled from the second end of the exhaust duct and an overall height of the exhaust subsystem is reduced.

8 . The system of claim 7 , wherein the turnover mechanism is driven hydraulically or electrically.

9 . The system of claim 7 , wherein the system further comprises a position sensor for detecting a rotational position of the exhaust silencer relative to the exhaust duct.

10 . The system of claim 9 , wherein the positional sensor is configured to generate signals to control a switching between the operational position and the idle position for the exhaust silencer.

11 . The system of claim 7 , further comprising a reduction gearbox disposed between the exhaust subsystem and the load.

12 . The system of claim 7 , wherein the exhaust silencer rests away from the turbine engine in the idle position.

13 . The system of claim 7 , further comprising an air intake assembly for the turbine engine.

14 . The system of claim 13 , wherein the air intake assembly is disposed above the turbine engine.

15 . The system of claim 14 , wherein the air intake assembly is disposed lower than an exit of the output exhaust of the turbine engine at the exhaust silencer in the operation position.

16 . The system of claim 14 , wherein the exhaust silencer comprises a silencer section and an extended section to guide the output exhaust of the turbine engine higher than the air intake assembly.

17 . The system of claim 7 , wherein the load comprises a plunger pump or an electric generator.

18 . The system of claim 7 , further comprising a cap pivotally connected to the second end of the exhaust duct and slidably coupled to the exhaust silencer.

19 . A system, comprising:

a turbine engine;

an exhaust subsystem of the turbine engine configurable into an operational state and an idle state distinct from the operational state; and

a load drivable by the turbine engine from an exhaust end of the turbine engine via at least one driving shaft that passes through walls of an exhaust duct of the exhaust subsystem, the exhaust duct being connected to an exhaust side of the turbine engine and being separate from the turbine engine;

wherein the exhaust subsystem comprises the exhaust duct and an exhaust silencer;

wherein the turbine engine, the exhaust subsystem, and the load are installed on a common base;

wherein the system further comprises a turnover mechanism comprising an extendable and contractible telescopic structure; and

wherein one end of the extendable and contractible telescopic structure is anchored on the common base and another end of the extendable and contractible telescopic structure is anchored to an outer wall of the exhaust silencer.
