[0022] The following are specific embodiments of the present application, and the technical solutions of the present application are further described in conjunction with the drawings, but the present application is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required by the solutions of the utility model.

[0023] The principles and structures of the present application will be described in detail below in conjunction with the drawings and embodiments.

[0024] Embodiment one

[0025] As shown in Figure 1 , 2 , a power tower, comprising a tower pole 1, further comprising a support pole 2, the upper end of the support pole 2 is connected with the tower pole 1 through a first shaft hinge 3, so that the support pole 2 can rotate freely relative to the tower pole 1 around the first shaft hinge 3. The rotation shaft of the first shaft hinge 3 is perpendicular to the tower pole 1, when the tower pole 1 is upright, the lower end of the support pole 2 is higher than the ground where the tower pole 1 is located, so that when the tower pole 1 is in the vertical state, the support pole 2 naturally approaches the tower pole 1 and is arranged nearly parallel to the tower pole 1, so as to reduce the occupation of too much bottom space. When the tower pole 1 is inclined, the height of the first shaft hinge 3 from the ground becomes smaller, under the action of gravity, the support pole 2 rotates around the rotation shaft and naturally droops, and then the lower end of the support pole 2 is supported on the ground, thereby playing an auxiliary supporting role and preventing the tower pole 1 from continuing to incline, so as to provide time for workers to repair.

[0026] The tower pole 1 is circumferentially uniformly distributed with a plurality of support poles 2, different support poles 2 are used to support inclination in different directions, in order to achieve better auxiliary support, preferably not less than three support poles 2.

[0027] An electromagnet 54 for attracting the support pole 2 is arranged on the tower pole 1 below the first shaft hinge 3, an inclination sensor (also called an inclination sensor) for detecting the inclination state of the tower pole 1 is arranged on the tower pole 1, and the electromagnet 54 controls the change of the magnetic field according to the detection information of the inclination sensor. The support pole 2 is a steel pipe that can be attracted by a magnetic field, the electromagnet 54 generates a magnetic field to make the support pole 2 be attracted to the tower pole 1, avoiding the free rotation of the support pole 2, and when the inclination of the tower pole 1 is detected, the magnetic field disappears, so that the support pole 2 rotates freely, thereby playing a supporting effect.

[0028] The support rod 2 is equipped with a magnet 5 corresponding to the electromagnet 54 on the tower 1. When the support rod 2 needs to be attracted, the magnetic pole direction of the electromagnet 54 is opposite to that of the magnet, so that the support rod 2 is attracted to the tower 1. However, when the tower 1 is tilted, the magnetic pole direction of the electromagnet 54 is opposite to that of the magnet, so that it generates a repulsive force on the support rod 2, causing the support rod 2 to quickly leave the tower 1, thus providing support.

[0029] The lower end of the support rod 2 is provided with a crossbar 6. The lower end of the support rod 2 is rotatably connected to the crossbar 6 through a second shaft hinge 7. When the tower 1 tilts, the support rod 2 is supported on the ground through the crossbar 6, thereby increasing the contact area with the ground.

[0030] The electromagnet 54 is positioned corresponding to the crossbar 6, so that the electromagnet 54 can simultaneously attract the crossbar 6 and the support rod 2, thereby facilitating better fit between the crossbar 6 and the support rod 2 relative to the tower rod 1 and reducing the space occupied.

[0031] Example 2

[0032] like Figure 3 As shown, the first shaft hinge 3 is mounted on the sliding sleeve 8, which slidably fits onto the tower 1. When the tower 1 tilts, gravity causes the support rod 2 to rotate in the direction of the tilt, thus providing support. A clamp 9, adjustable in height along the tower 1, can be installed on the tower 1, and the sliding sleeve 8 is rotatably supported on the clamp 9.

[0033] To enable the support rod 2 to rotate quickly and accurately to the tilted position, a motor 10 can be installed on the tower 1 to drive the sliding sleeve 8 to rotate. This actively controls the rotation of the sliding sleeve 8, causing the support rod 2 to rotate in the tilted direction, thus providing timely auxiliary support. The tower 1 is equipped with a tilt sensor to detect the tilt state of the tower 1. The motor 10 controls the rotation of the sliding sleeve 8 based on the detection information from the tilt sensor. According to the detected tilt direction, the motor 10 rotates the support rod 2 to the required support position. Specifically, a driven gear 11 can be coaxially fixedly sleeved on the sliding sleeve 8, and a drive gear 12 can be installed on the shaft of the motor 10. The driven gear 11 meshes with the drive gear 12, allowing the motor 10 to drive the sliding sleeve 8 to rotate via the driven gear 11 and the drive gear 12.

[0034] Example 3

[0035] like Figure 4As shown, the tower pole 1 is provided with a displacement sensor for monitoring the distance between the support pole 2 and the tower pole 1, and the displacement sensor is connected to a remote monitoring device through a network signal. The displacement sensor can be a touch switch 13 arranged on the tower pole 1. When the tower pole 1 is upright, the support pole 2 presses the touch switch 13. When the tower pole 1 is tilted, the support pole 2 is away from the tower pole 1 and thus is separated from the touch switch 13, so that the touch switch 13 generates a signal change. The signal can be transmitted to the remote monitoring device through a wireless network, so that the staff can find the tilt of the tower pole 1 in time.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
