Device and method for detecting space inclination angle of drill string

The invention discloses a drill string space inclination angle detection device which comprises a racking platform pipe arrangement device, the racking platform pipe arrangement device is connected with a pair of clamping pliers, and the clamping pliers are connected with a tool standard drill rod in a clamping mode. The invention relates to a drill string space inclination angle detection method. The method specifically comprises the following steps: step 1, installing an inclination angle sensor on a tool standard drill rod; step 2, clamping the tool standard drill rod by a pair of clamping pliers; step 3, reading two axial output values by a tilt angle sensor; 4, calculation is conducted according to the property of the diagonal included angle of the cuboid, and the space inclination angle of the tool standard drill rod is determined according to the output numerical value obtained in the step 3; and step 5, outputting the inclination angle theta. According to the drill string space inclination angle detec
