Description

Technical Field

[0001] The utility model relates to the technical field of power transmission equipment, in particular to a line anti-icing device. Background Art

[0002] The transmission of electric energy is achieved by stepping up the voltage of the electric energy generated by the generator through a transformer, and then connecting it to the transmission line through control equipment such as circuit breakers. Transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines require transmission towers and are exposed to the natural environment. If the overhead transmission lines encounter cold and snowy weather, it is easy for snow and ice to accumulate on the wires, thereby increasing the load on the towers and racks, which has a great impact on safe power transmission. In severe cases, the towers collapse, the wires are damaged, and it is difficult to restore them in time, affecting people's normal life and production, and causing serious economic losses.

[0003] Therefore, it is necessary to use anti-icing devices to protect the lines and remove the accumulated snow and ice on the transmission lines. At present, the methods of snow and ice removal for transmission lines are mostly DC ice melting, drone ice removal and mechanical impact ice removal, which can effectively remove snow and ice. However, DC ice melting cannot remove ice when the line is energized, and cannot meet the needs of removing ice and snow from the ground wire; considering the cost and efficiency of ice removal, drone ice removal and mechanical impact ice removal methods are only used after a certain amount of snow or ice accumulates on the transmission line. Deicing operations are not started by drones or impact methods as soon as snow or ice accumulates. However, in the process of accumulating a sufficient amount of snow or ice on the transmission line, as the weight of the transmission line increases, the sag increases, and the distance between the wire and the ground decreases, so flashover accidents may also occur. While the sag increases, under the action of wind, the two wires or the wire and the ground may collide, causing short circuit tripping, burns or even burnout of the wire. It can be seen that this method that cannot remove ice and snow at any time still has limitations.

[0004] Therefore, there is a need for a device that can remove ice and snow on the ground wire of a transmission line at any time, is not affected by the amount of snow or ice accumulated on the transmission line, can check the amount of ice and snow covering the transmission line at any time, and then remove ice according to demand. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a line anti-icing device, which removes ice and snow by installing vibration devices at both ends of the transmission line. At the same time, multiple information collection devices are installed, so that various types of information of the transmission line can be viewed in real time, thereby achieving the effect of removing ice and snow in time.

[0006] The utility model discloses a line anti-icing device through an embodiment, including a vibration device, an information collection module, a processor, a communication module, a power supply, a controller, a first protection box and a second protection box. The vibration device is installed in the first protection box; the power supply, the processor, the controller and the communication module are installed in the second protection box; the vibration device is connected to the power supply, and the controller is set on the circuit of the vibration device and the power supply to control the opening and closing of the vibration device; the information collection module is connected to the power supply, and the information collection module and the controller are respectively connected to the communication module by electrical signals; the processor is connected to the information collection module, the communication module and the controller by electrical signals. When using the device, the processor receives the information of the information collection module and determines whether to control the vibration of the vibration device through the controller; or the communication module receives the remote control instruction, and then the controller controls the vibration of the vibration device, and finally drives the transmission line to vibrate, so as to achieve the purpose of removing ice and snow.

[0007] Furthermore, the power supply includes a battery. Since the voltages of the electric energy transmitted by each transmission line are not exactly the same, and it is not convenient to use the electric energy on the transmission tower as the power supply for driving the vibration device, a unified power supply is provided for the anti-icing device of this line.

[0008] Preferably, the line anti-icing device also includes a power generation device, which is connected to a power source to charge the power source. Since the transmission line is a long-term use device, its battery also needs to be able to replenish the power supply in time.

[0009] Furthermore, it also includes a ground master control device, which is connected to the information acquisition module, the processor, the power generation device and the controller respectively. The ground master control device further controls each device by obtaining information from the information acquisition module, the processor, the power generation device and the controller. For example, the operator obtains the remaining power information of the power supply, determines whether it is necessary to supplement the power, and if necessary, controls the power generation device to charge the power supply.

[0010] Furthermore, the power generation device includes one or more of a solar panel, a wind power generation device and a gasoline engine power generation device. When in use, solar energy, wind power or gasoline can be used to generate electricity to supplement the battery. Since there are a large number of transmission towers, and some are erected on mountains with inconvenient transportation, it is best for the line anti-icing device to have its own power generation device to charge the battery, so that it can be used uninterruptedly for a long time.

[0011] Furthermore, the vibration device includes a vibration motor, and preferably the vibration motor includes a high-frequency low-amplitude vibration motor. The high-frequency low-amplitude vibration motor has a better vibration effect and can better remove the ice and snow accumulated on the transmission line.

[0012] Furthermore, the communication module includes one or more of an NB-IoT communication module, a 4G communication module, a 5G communication module, a ZigBee communication module or a GPRS communication module, which receives control information through radio signals, or transmits relevant parameter information of the transmission line collected by the information collection module, thereby being able to remotely grasp the snow and ice conditions of the transmission line and remove snow and ice in a timely manner.

[0013] Furthermore, the information acquisition module includes one or two of an ice and snow thickness monitoring device and a video monitoring device, or also includes one or more of a temperature acquisition device, a humidity acquisition device, a wind direction monitoring device, a wind speed monitoring device, a power current monitoring device, and an ultrasonic monitoring device. The aforementioned various information acquisition devices are installed inside or outside the second protection box according to the actual use situation and their own installation requirements to collect various data. Among them, the ice and snow thickness monitoring device and the video monitoring device can collect the ice and snow coverage on the transmission line, and then transmit the data to the processor, and the processor determines whether to turn on the vibration device to remove the ice and snow; the temperature acquisition device, the humidity acquisition device, the wind direction monitoring device, the wind speed monitoring device, the power current monitoring device, and the ultrasonic monitoring device are used to monitor their respective corresponding information, and after collecting this information, the communication module is used to send it, so that the collected information is more complete and convenient for the background staff to monitor. It is worth noting here that the various types of information collected by the information acquisition module can also be sent to the ground main control center or machine room by the communication module, and the ground control personnel can view various information of the transmission line in real time.

[0014] Furthermore, the first protection box includes a first box body and a first box door, the first box body and the first box door are connected by a hinged manner; a sealing strip is also provided between the first box body and the first box door, which can effectively prevent water vapor and dust from entering the box body and affecting the vibration device inside the box body. Similarly, the second protection box includes a second box body and a second box door, the second box body and the second box door are connected by a hinged manner; a sealing strip is also provided between the second box body and the second box door, which can effectively prevent water vapor and dust from entering the box body and affecting the power supply and other devices inside the box body.

[0015] The technical principle of the utility model is: in snowy weather, the user can transmit a signal through the communication module to control the controller to turn on the switch of the vibration device, and turn on the vibration device to perform vibration snow removal and ice removal. The various information collection devices in the information collection module can also collect various parameter information of the power transmission line, and according to the information of the tension sensor on the transmission line, the processor determines whether to control the vibration device to start for vibration snow removal and ice removal.

[0016] Compared with the prior art, the utility model has the following beneficial effects: through the communication module and the information collection module, the ice and snow coverage of the transmission line in snowy weather can be obtained in real time. When the transmission line is found to be covered with ice and snow, the vibration device is turned on through the communication module to remove snow or ice in time; the processor can also judge whether it is necessary to turn on the vibration device for deicing based on the data of the information collection module and the data of the tension sensor on the transmission line. The entire line anti-icing device has the characteristics of high automation, ability to remove ice and snow at any time, and saving manpower. BRIEF DESCRIPTION OF THE DRAWINGS
