The invention provides an inclination detecting device for a pole and an anti-inclination device. The inclination detecting device for the pole includes that an inclination sensor detects a current angle of the pole inclining relative to the gravity direction and sends the current angle to a controller; the controller compares the current angle with a preset angle, and sends alarm information to an alarm device if the current angle is greater than the preset angle; and a GPRS positioning device sends the position information of the pole to a user terminal. The anti-inclination device includesthe inclination detecting device for the pole and also includes a pedestal. Two ends of the bottom of the pedestal are provided with a first limiting device and a second limiting device. The center ofthe pedestal is provided with a groove. A support part is arranged in the groove. An inner rotary shaft is arranged in the support part. A sleeve is arranged on the inner rotary shaft. A spiral groove and a support shaft inserted into the sleeve and matched with the spiral groove are arranged on the inner side wall of the sleeve. The inclination condition of the pole can be detected timely through the inclination sensor. The anti-inclination device supports the pole and prevents inclination of the pole.
