Description

TECHNICAL FIELD

[0001] The present application relates to a tilt alarm system of a tower, in particular, the present application relates to a tilt alarm system of a power transmission tower in a prone-settlement area. BACKGROUND

[0002] It is known that the main cause of the tilt of the power transmission tower is the uneven foundation or the subsidence of the foundation, and the tilt of the power transmission tower is mainly concentrated in the geological disasters caused by the instability of the internal force distribution of the structure caused by the various mine goaf, soft soil area, hilly slope or land slope topographic transition area, once the tilt of the power transmission tower occurs, it will inevitably lead to the partial deformation of the steel structure of the tower, and further lead to the collapse of the power transmission tower and cause major accidents; the tilt of the power transmission tower needs to be considered is that the connection between the tower leg and the lower unevenly settled foundation pile is subjected to the deformation of the lower pull, the soil around the concrete foundation pile is the place where the stress concentration is more obvious, the soil surface in contact with the bottom surface of the concrete foundation pile bears the gravity transmitted by the power transmission tower and the foundation pile, and the soil in contact with the side surface of the concrete foundation pile bears the stress in the direction of the root opening of the foundation, after the deformation of the steel structure of the power transmission tower, the tower leg sinks first, if the settlement problem is found and repaired in time, most of the subsequent accidents can be avoided. SUMMARY

[0003] The purpose of the present application is to disclose a tilt alarm system of a power transmission tower in a prone-settlement area based on the existing deficiencies, the four electrical contacts of the cross-shaped support mechanism are used to perceive the settlement changes of the four tower legs, and once the power supply of the alarm device is turned on, an alarm signal is quickly sent to the power operation and maintenance center.

Four double-inner-folded channel steels are fixed at the same horizontal position on the upper part of the tower legs. The end risers are placed in the C-shaped placement openings of the double-inner-folded channel steels. The lower end of the gravity rod inserted into the pipe hole of the end riser abuts against the bottom plate of the lower end of the double-inner-folded channel steel. The gravity head set at the upper end of the gravity rod is supported by the bottom plate through the gravity rod. A blind hole is set on the lower surface of one side of the gravity head. Contact A is installed on the upper part of the blind hole. A lifting cylinder is set at the lower part of the blind hole. The contact rod is located in the bottom opening of the bottom plate of the lifting cylinder. A gravity block is set at the upper end of the contact rod. Contact B is fixed on the upper surface of the gravity block. There is a gap between contact A and contact B. Contact A is connected to the alarm device through wire A, and contact B is connected to the battery through wire B. When any of the four foundation piles at the bottom of the tower sinks, causing the tower to tilt, the corresponding end riser of the cross-shaped support mechanism is lifted into the air. At this time, the upper end face of the end riser presses against the contact rod, causing the gravity block to rise. Then, contact B comes into contact with contact A, and at the same time, conductor A and conductor B are connected to form a conductor. The alarm device is powered on, and the information management module of the alarm device sends the alarm signal, including location information, tower number, and time information, to the power operation and maintenance center through the remote control interaction module.

[0005] The aforementioned alarm system for tilting transmission towers in areas prone to subsidence has an alarm device installed in the alarm system box located at the junction of the cross-shaped support structure.

[0006] The aforementioned tilt alarm system for power transmission towers in easily subsidence areas includes a cross-shaped support mechanism comprising a connecting box, an alarm system box, an outer sleeve, an inner pull-out tube, and an end riser. An inlet for conductors A and B is provided between the connecting box and the upper-mounted alarm system box. The inner ends of the four outer sleeves are fixedly connected to the connecting box. The inner ends of the four inner pull-out tubes are respectively inserted into the holes of the outer sleeves. The end riser is fixedly connected to the outer ends of the inner pull-out tubes. A through hole is provided in the connection surface between the hole of the end riser and the inner pull-out tube.

[0007] The aforementioned alarm system for tilting transmission towers in easily subsidence areas has four outer sleeves and four inner pull-out tubes, each with a recessed groove structure on the middle of both sides. The inner pull-out tubes are inserted into the outer sleeves, and the outer wall of the inner pull-out tubes and the tube holes of the outer sleeves are matched.

[0008] The aforementioned alarm system for tilting transmission towers in easily subsidence areas has a groove at the through hole on one side of the inner pull-out pipe of each end riser pipe hole.

[0009] The aforementioned alarm system for tilting transmission towers in easily subsidence areas has a fixed cylinder fixed in a blind hole on the lower side of the gravity head. An opening A is provided between the blind hole of the gravity head and one side wall. An opening B is also provided at the corresponding opening A of the fixed cylinder. Openings A and B are used for the entry of conductor A. Contact A is fixed on the upper wall of the fixed cylinder, and a support cylinder is inserted into the lower inner wall of the fixed cylinder.

[0010] The aforementioned alarm system for tilting transmission towers in easily subsidence areas has an opening C on the upper part of one side of the support cylinder.

[0011] Based on the above disclosure, the beneficial effects of the present invention are: The present invention relates to a tower tilt alarm system for easily subsidence areas. The tower legs, each connected to one of the four foundation piles, are equipped with double-inwardly folded channel steel with a bottom plate on their upper parts. The double inward folds prevent the end riser from detaching and stabilize its vertical movement. At this time, the lower end of the gravity rod presses against the bottom plate, creating a gap between the lower end of the contact rod and the upper surface of the end riser. When any of the four foundation piles settles, the bottom plate of the double-inwardly folded channel steel descends, causing the gravity rod to descend as well. Simultaneously, the gravity head descends, causing the contact rod to contact the upper surface of the end riser. The contact rod then moves the gravity rod... The upward force of the block causes contact B to come into contact with contact A. At this time, the wire B connecting contact B and the wire A connecting contact A are connected to form a conductor. The alarm device then connects to the power supply and activates its built-in power signal data processing module. After signal processing and analysis, the power signal data processing module generates information, including location information, tower number, and time information, which is sent to the power operation and maintenance center for handling. This invention has low cost and high sensitivity, and can send information to the power operation and maintenance center immediately after the transmission tower subsidence, avoiding major accidents caused by continued subsidence.
