Claim 8:
9. An inclinometer, comprising a pure mechanical well deviation wireless measure-while-drilling and mud pulse generation device, an inclinometer outer cylinder and an eccentric rotary column,
wherein the pure mechanical well deviation wireless measure-while-drilling and mud pulse generation device comprises
an outer cylinder and an inner cylinder coaxially arranged inside the outer cylinder of the device,
wherein an inner flow channel is formed inside the inner cylinder, and an annular outer flow channel is formed between the inner cylinder and the outer cylinder of the device;
wherein a flow control valve and a hydraulic turbine are arranged inside the inner flow channel, and the flow control valve is located at an upstream section of the hydraulic turbine;

the device further comprises
a signal generation base arranged between the outer cylinder of the device and the inner cylinder, and
a rotary stopper assembled with the hydraulic turbine;
wherein an overflow hole is formed in the signal generation base and arranged in the annular outer flow channel; and
when the hydraulic turbine drives the rotary stopper to rotate, the rotary stopper periodically shields the overflow hole so as to change overflow area of the outer flow channel;

wherein the outer cylinder of the device is fixedly connected to the inclinometer outer cylinder, the eccentric rotary column is coaxially and rotationally arranged inside the inclinometer outer cylinder, the eccentric rotary column is coaxially and fixedly connected to the flow control valve, and a gravity control module is arranged in the flow control valve.
