Description

Technical Field

[0001] The invention relates to the field of pole tower force monitoring, in particular to a pole tower force monitoring device. Background Art

[0002] Looking at the extreme meteorological disasters caused by severe low temperature, rain, snow and freezing in the southern region, its characteristics are wide range, high intensity and long duration. Especially in the extreme conditions such as ice coating on large-span overhead lines in high-cold mountainous areas, the ice-covered conductors put too much load on the poles and towers, which will cause pole or tower collapse accidents. The Southern Power Grid has been monitoring the ice coating in the transmission and distribution network line area to ensure the safe and stable operation of the line. Although meteorological monitoring has been carried out on the line corridor, and meteorological conditions and possible ice coating in different regions and terrains have been studied and analyzed, the ice and snow disasters in the south are not accidental, but the main cause of endangering the safety of the line under special geographical and terrain conditions. How to strengthen the line operation maintenance and monitoring of the ice-covered areas of the line corridor is the key to ensuring the safe operation of the line.

[0003] The existing monitoring method generally transmits the detection data remotely to the monitoring platform, and the monitoring platform arranges subsequent work according to the parameters obtained after processing the detection data. However, this remote transmission method is susceptible to interference, resulting in untimely data transmission, transmission failure or data errors. At this time, inspection personnel are extremely important, but inspection personnel can only observe the stress conditions of the tower and cannot know the actual stress conditions.

[0029] The following is combined with Figure 1-2 The present invention is described in further detail.

[0030] Embodiment 1: A tower force monitoring device is disclosed, referring to Figure 1 , including a tension sensor 30, a data acquisition processor 40 and a power supply module; wherein the tension sensor 30 is connected in parallel between the wire clamp of the insulator string 20 and the pole tower 10; the data acquisition processor 40 and the power supply module are both fixed on the pole tower 10; the power supply module supplies power to the tension sensor 30 and the data acquisition processor 40; the data acquisition processor 40 is electrically connected to the tension sensor 30; when working, the tension sensor 30 detects the tension between the pole tower 10 and the guy wire or the conductor and transmits it to the data acquisition processor 40 in the form of electrical signals, and the data acquisition processor 40 processes and stores these electrical signals.

[0031] refer to Figure 1 and Figure 2The data acquisition processor 40 includes a shell 41, a data processing module 44 and a display module 45; the data processing module 44 is arranged in the shell 41; the data processing module 44 is arranged on the shell 41; the data processing module 44 is electrically connected to the tension sensor 30 and the display module 45 respectively; when the tension sensor 30 detects the tension between the pole tower 10 and the guy wire or the conductor and transmits it to the data processing module 44 in the form of an electrical signal, the data processing module 44 stores and processes these electrical signals and displays the tension value through the display module 45, so that the inspection personnel can intuitively view the tension applied by the conductor or the guy wire to the pole tower, so as to make processing easier and more accurately. In order to increase the service life of the data acquisition processor 40, the shell 41 is designed to be waterproof. For example, the shell 41 is made of waterproof and corrosion-resistant materials such as stainless steel and aluminum alloy, the wiring terminals are coated with waterproof glue or special waterproof wiring terminals are used, waterproof sleeves or waterproof connectors are installed at the inlet and outlet ports, and waterproof strips are used at the gaps in the shell. At the same time, the shell 41 is designed to be anti-ice and snow, such as providing a fluorine-containing polymer coating on the shell 41 to effectively prevent the accumulation of ice and snow and enhance the anti-icing ability.

[0032] refer to Figure 1 and Figure 2 , the power supply module includes a solar panel 50, a lithium battery module 43 and a power charge and discharge management circuit; the solar panel 50 is located outside the housing 41 and installed on the pole tower 10; the lithium battery module 43 is installed in the housing 41; when there is sunlight, the solar panel 50 converts light energy into electrical energy, a part of which is stored in the lithium battery module 43, and the other part is used to power the tension sensor 30 and the data acquisition processor 40; when there is no sunlight, the lithium battery module 43 powers the tension sensor 30 and the data acquisition processor 40. The power charge and discharge management circuit monitors the power consumption of the device in real time, timely controls the power supply of each functional module and monitors the charging and discharging status of the lithium battery, ensures that the lithium battery is not overcharged or overdischarged, and ensures that the lithium battery safely provides energy for the equipment. The above method makes full use of solar energy, so that the power supply module can continuously supply power; of course, it can also use urban electricity at the same time, so that when there is a problem with the solar panel 50 and the power in the lithium battery module 43 is exhausted, the tension sensor 30 and the data acquisition processor 40 are powered, making the power supply more stable. In addition, in some places where wind resources are relatively abundant, wind power generation devices can also be integrated, or wind power generation devices can be used instead of solar panels 50, so that the power supply is more stable.

[0033] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that: in order to further facilitate the inspection personnel, refer to Figure 1The monitoring device also includes a mobile control terminal 60, and the data acquisition processor 40 also includes a wireless communication module 42 arranged in the shell 41; the power supply module supplies power to the wireless communication module 42; the wireless communication module 42 is electrically connected to the data processing module 44; the mobile control terminal 60 communicates with the data acquisition processor 40 through the wireless communication module 42; in this way, the inspection personnel can use the mobile control terminal 60 on the ground to realize one-click on-site call for inspection, read the data stored in the data processing module 44 and the data detected in real time, and the data is displayed in the form of tension values; such a short-distance point-to-point transmission method is far more stable and accurate than long-distance data transmission.

[0034] Embodiment 3: Embodiment 3 is different from Embodiment 1 in that: when encountering an emergency situation where the pulling force exceeds the set value, in order to allow the inspection personnel to know the situation more quickly and carry out emergency treatment, the data acquisition processor 40 includes an alarm electrically connected to the data processing module 44, and when encountering the above emergency situation, the alarm sounds an alarm. The alarm can be a sound alarm or a light alarm, or a combination of a sound alarm and a light alarm. Of course, the combination of a sound alarm and a light alarm is the best, so that the alarm is more obvious, and when one of the two has a problem, the alarm function can still be realized.

[0035] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
