Technical Field

[0001] This invention relates to the field of power transmission tower settlement protection, and in particular to a device and method for monitoring, early warning and protection against power transmission tower settlement. Background Technology

[0002] Transmission towers, as the support points for overhead lines, have high safety requirements. my country's power grid is widely distributed across diverse geological conditions, inevitably traversing challenging geological zones such as rocky areas, soft soil areas, and coal mining areas during transmission tower construction.

[0003] Due to adverse geological conditions, transmission tower foundations are prone to uneven settlement, which can lead to tower tilting or even collapse, causing significant disruption to production and daily life, resulting in substantial economic losses and posing significant safety hazards. Therefore, effective monitoring, early warning, and protection against transmission tower settlement are crucial for preventing such accidents. Traditional building settlement monitoring primarily employs leveling, a method requiring regular manual on-site measurements. This method is dependent on weather conditions, presents significant construction challenges, has low efficiency, and cannot provide real-time monitoring. Furthermore, this method requires recording monitoring data for each instance and comparing it to obtain the tower's settlement status, which is not timely and poses a considerable safety risk. Therefore, this invention aims to design a device capable of real-time monitoring, wireless early warning transmission, and protective measures when tower settlement exceeds warning thresholds. Summary of the Invention

[0005] In a first aspect, the present invention provides a device for monitoring, early warning, and protecting against settlement of power transmission towers, applied to power transmission towers, comprising:

[0006] The spiral support column includes a column body and a circumferential spiral around the column body. The spiral support column is connected to four corner piles by a telescopic connecting rod. The four corner piles are set at the four corners of the bottom of the transmission tower body. The top of the column body of the spiral support column is horizontally aligned with the top of the four corner piles.

[0007] Settlement monitoring equipment and settlement early warning equipment are installed at the top of the spiral support column;

The four scale columns are respectively connected to the four corners of the bottom of the transmission tower body via crossbars. The disc is installed at the lower end of the four scale columns. The lower end of the disc is connected to the springs, and the springs are connected to the settlement early warning device.

[0009] Furthermore, the telescopic connecting rod includes: a hollow cylinder, a piston rod that slides in the hollow cylinder, and connecting pieces respectively disposed at the ends of the piston rod and the hollow cylinder; the connecting pieces at both ends of the telescopic connecting rod 14 connect the spiral support column and the four corner piles.

[0012] Furthermore, the scale column is provided with scale values. The settlement value of the transmission tower is obtained by comparing the existing scale of the scale column with the original calibration scale. The original calibration scale is the scale at the beginning of the installation of the transmission tower settlement monitoring, early warning and protection device. The settlement amount obtained by the scale column is used to verify the settlement data received by the settlement early warning device.

[0013] Secondly, the present invention provides a method for monitoring, early warning, and protection against settlement of transmission towers, applied to the aforementioned device for monitoring, early warning, and protection against settlement of transmission towers, comprising:

[0014] The transmission towers are numbered, and a mapping relationship is established between the transmission tower numbers and the MAC addresses of the signal transmitting equipment in the aforementioned transmission tower settlement monitoring, early warning and protection device;

[0015] When the settlement early warning device periodically receives the settlement data of the transmission tower through the signal transmitting device, it determines the transmission tower to which the settlement data belongs based on the MAC address and the mapping relationship, and iterates through all the settlement data to check whether it exceeds the preset early warning value.

[0016] Furthermore, the settlement data received by the settlement early warning device is periodically verified using the settlement amount obtained from the scale column in the aforementioned power transmission tower settlement monitoring, early warning and protection device.

[0017] Furthermore, the alarm indicates the number of the transmission tower. Maintenance is performed on the corresponding transmission tower according to the number indicated in the alarm. After the foundation of the transmission tower is stabilized, the transmission tower settlement monitoring, early warning and protection device is recalibrated.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0031] Example 1

[0032] See Figure 1 As shown, this embodiment of the invention provides a settlement monitoring, early warning, and protection system for power transmission towers, applied to power transmission tower 1, comprising:

[0033] A spiral support column 2, consisting of a column body and a surrounding spiral, is integrally connected to four corner piles 13 via telescopic connecting rods 14. The four corner piles 13 are located at the bottom of the transmission tower 1, serving as supports for the transmission tower 1.

[0034] See also Figure 1 and Figure 3 As shown, the four corner piles 13 are arranged in a rectangular array, and the spiral support columns 2 are installed at the intersection of the diagonals of the array. (See reference...) Figure 1 and Figure 2As shown, when installing the power transmission tower and a power transmission tower settlement monitoring, early warning, and protection device, the top of the spiral support column 2 is horizontally aligned with the top of the four corner piles 13 to form a settlement observation benchmark. The spiral around the column can increase the friction between the spiral support column 2 and the soil, thereby enhancing the bearing capacity of the spiral support column 2 and reducing the impact of the settlement of the four corner piles 13 on the spiral support column 2.

[0035] In the specific implementation process, refer to Figure 1 and Figure 5 As shown, the telescopic connecting rod 14 includes: a hollow cylinder 16, a piston rod 15 sliding on the hollow cylinder 16, and connecting pieces 17 respectively disposed at the ends of the piston rod 15 and the hollow cylinder 16. The connecting pieces 17 at both ends of the telescopic connecting rod 14 connect the spiral support column 2 and the four corner piles 13. Specifically, the diameter of the opening of the hollow cylinder 16 is smaller than the diameter of the cylinder body and the diameter of the piston rod 15, allowing the piston rod 15 to move in a piston-like motion within the hollow cylinder 16. The connecting pieces 17 are hinged. During installation, a reserved sliding allowance is left between the hollow cylinder 16 and the piston rod 15. If the settlement of the transmission tower exceeds the reserved distance, the telescopic connecting rod 14 will be stretched by the settlement pressure of the four corner piles 13 to form a tie rod, which, together with the spiral support column 2, provides tensile support to the four corner piles 13, preventing excessive settlement of the transmission tower.

[0036] See Figure 4 As shown, the top of the spiral support column 2 is provided with a chamber 3 having four perforations. Settlement monitoring equipment and settlement early warning equipment are installed in the chamber 3, with the settlement early warning equipment installed below the settlement monitoring equipment.

[0037] In specific implementation, the settlement monitoring device includes: a disc 6, scale columns 5, and springs 7 installed at the top of the spiral support column 2. The scale columns 5, passing through the perforations, are connected to the four corners of the bottom of the transmission tower 1 via crossbars 4. Specifically, one end of the crossbar 4 is welded to the four corners of the bottom of the transmission tower 1, and the other end is welded to the top of the scale columns 5. When the transmission tower settles, the pressure and settlement of the tower body can be transmitted to the scale columns 5 through the crossbars 4. The disc 6 is installed at the lower end of the four scale columns 5 to increase the contact area with the scale columns 5, facilitating force monitoring. The lower end of the disc 6 is connected to the springs 7, which play a role in shock absorption and conversion when the transmission tower 1 settles, protecting the settlement early warning device at the lower end. When the transmission tower 1 sinks, it will cause the scale columns 5 to sink as well. The amount of settlement of the transmission tower 1 can be directly reflected from the change in the scale value of the scale columns 5. The scale column 5 needs to be calibrated during installation, and the original scale data of the initial design of the transmission tower 1 needs to be recorded so that the settlement amount can be calculated by comparing the data when the transmission tower 1 settles.

[0038] In specific implementation, the settlement early warning device includes: a piezoelectric pressure sensor 8, a charge amplifier 9, a signal converter 10, a signal transmitting device 11, and a signal receiving device 12. The piezoelectric pressure sensor 8 is electrically connected to the charge amplifier 9, the charge amplifier 9 is electrically connected to the signal converter 10, and the signal converter 10 is electrically connected to the signal transmitting device 11. The piezoelectric pressure sensor 8 is connected to the lower end of the spring 7 and receives the pressure transmitted by the spring 7. The settlement amount reflected by the scale column 5 is converted into elastic force information by the spring 7 and acts on the piezoelectric pressure sensor 8. The piezoelectric pressure sensor 8 is made using the positive piezoelectric effect. When the piezoelectric pressure sensor receives pressure from above, it generates an electric charge and transmits it to the charge amplifier 9. The charge amplifier 9 can convert the weak electric charge signal output by the sensor into an amplified voltage signal, and the electrical signal is proportional to the pressure at the upper end. The charge amplifier 9 processes the charge and transmits it to the signal converter 10. The signal converter 10 receives the voltage signal from the charge amplifier 9, calculates the settlement of the transmission tower based on the positive piezoelectric principle of the piezoelectric pressure sensor 8, and transmits it to the signal transmitting device 11. The signal transmitting device 11 sends the settlement data of the transmission tower to the remote signal receiving device 12. If the settlement of the transmission tower exceeds the warning value, the signal receiving device 12 will issue a warning to remind the staff that the tower has settled.

[0039] In practical applications, the settlement data received by the signal receiving device 12 is calibrated using the scale values ​​on the scale column 5.

[0040] The working principle of the power transmission tower settlement monitoring, early warning and protection device provided by the present invention is as follows:

[0041] When the transmission tower 1 settles, the transmission tower 1 transmits pressure to the scale column 5 through the crossbar 4, causing the scale column 5 to sink. The scale column 5 causes the disk 6 and the spring 7 to sink together. The spring 7 converts the settlement amount into elastic force and transmits it to the piezoelectric pressure sensor 8. The piezoelectric pressure sensor 8 generates charge due to the elastic force and transmits it to the charge amplifier 9. The charge amplifier 9 converts the weak charge signal into an amplified voltage signal and transmits it to the signal converter 10. The signal converter 10 converts the voltage signal into a digital signal that can reflect the magnitude of the transmission tower settlement and transmits it to the signal transmitting device 11. The signal transmitting device 11 wirelessly transmits the settlement data of the transmission tower to the remote signal receiving device 12. The signal receiving device 12 processes the data and alerts the staff that the transmission tower has settled. Meanwhile, if the settlement of the four corner piles 13 is too large, exceeding the distance reserved between the piston rod 15 and the hollow cylinder 16, the piston rod 15 and the hollow cylinder 16 will move relative to each other and stretch to form a tie rod. Together with the spiral support column 2, this tie rod provides tensile support to the four corner piles 13, preventing excessive settlement of the transmission tower foundation from triggering safety issues and providing time for emergency repairs. Based on this, when excessive settlement triggers the alarm system, workers can compare the existing scale of the scale column 5 with the original calibration scale to obtain the transmission tower settlement value and calibrate the data received by the signal receiving device 12.

If it exceeds the early warning value, it alarms via the signal receiving device, and the alarm indicates the transmission tower number.
