In order to overcome the defects of the handheld sliding inclinometer, the invention provides an intelligent fixed inclinometer, and the fixed inclinometer is used for combining the inclinometer monomers 2 when in operation, and for each measuring point, the inclinometer is installed in equal number according to the number of specified measuring distances, and the inclinometers work simultaneously and perform data acquisition. Through intelligent control, data are acquired in real time, the acquisition frequency is high, the minute level, the data are transmitted to a user side through a wireless communication module after being acquired, the data are checked in real time, the data acquisition is performed manually, the workload is small, and the accuracy of acquired data is high.

When the universal conversion head 231 is connected, the connecting part of the universal conversion head 231 with the threaded joint of the adjacent inclinometer monomers 2 is screwed and fastened in the threaded connecting hole 216 of the sensor top cap 212 of the adjacent other inclinometer monomers 2, and the fixing screw is screwed and fastened in the fixing screw hole 219, so that the universal conversion head 231 is locked in the threaded connecting hole 216 of the sensor top cap 212 through the fixing screw, and the connection between the adjacent two inclinometer monomers 2 is prevented from loosening in the use process of the inclinometer. It should be noted that, since there is no need to connect any other components to the head of the whole fixed inclinometer, there is no need to install a connecting rod 233 (shown in fig. 1) on the head of the whole fixed inclinometer, and a group of guide wheel set main bodies 22 are additionally installed on the end of the whole fixed inclinometer to increase the sliding stability of the inclinometer monomers 2 inside the inclinometer pipe 1 (shown in fig. 1).
In addition, it should be noted that when the plurality of connected and assembled inclinometer monomers 2 sequentially penetrate into the inclinometer pipe 1, it is required to ensure that the fixed guide wheel 222 and the swinging guide wheel 223 in each group of guide wheel set main bodies 22 are clamped into the guide rail 11, and sequentially penetrate into the inclinometer pipe 1, two wires, namely a power wire and a data wire, are reserved after the connection, and after the two wires are connected onto the intelligent control device, measurement can be performed, and after the measurement is completed, the plurality of connected and assembled inclinometer monomers 2 are pulled out from the inclinometer pipe 1.
