[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] Power transmission lines are frequently affected by ice and snow in winter, especially in cold regions. Icing on power lines severely impacts power supply stability and can even lead to line breaks and equipment damage. Moreover, transmission lines prone to icing are often located in mountainous or remote areas. Existing de-icing equipment for transmission lines mostly relies on mechanical methods or heat conduction for de-icing operations. These methods are limited in scope and time, resulting in low de-icing efficiency. In extreme conditions, there is a lack of highly efficient emergency response methods. Utility Model Content

[0004] To address the technical problems existing in the prior art, this utility model provides a power transmission line de-icing device based on high-temperature and high-pressure water flow. The device heats and pressurizes the pure water inside, and the high-temperature and high-pressure water flow can quickly and effectively flush away the ice layer on the power line, preventing the ice layer from causing equipment failure or line breakage, and ensuring the stable operation of the power system.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A de-icing device for power transmission lines based on high-temperature and high-pressure water flow includes a hollow housing. Inside the housing is a hollow high-temperature and high-pressure container. The container has an inlet at the top and an outlet on one side below. The outlet is connected to a spray structure via an electromagnetic control valve. An electric heating plate is attached to the bottom of the container and connected to a power source. A high-pressure pump is positioned between the housing and the container, connected to the container via a pipeline. A mounting structure is detachably installed at the center of the top of the housing. This mounting structure consists of a grid-shaped frame formed by multiple metal beams, fixed to the housing at their intersections.

[0007] A further technical solution is that the top side of the shell has an opening opposite the water inlet, and the other side of the top of the shell has a accommodating chamber.

[0008] In a further technical solution, a control unit and a battery unit connected thereto are fixedly installed inside the accommodating compartment.

[0009] In a further technical solution, the battery unit is connected to the control unit, the electric heating plate, the high-pressure pump, and the electromagnetic control valve, respectively.

[0010] In a further technical solution, the outlet of the high-temperature and high-pressure vessel is also equipped with a temperature sensor and a pressure sensor.

[0011] In a further technical solution, the temperature sensor and pressure sensor communicate with the control unit via a wireless communication module.

[0012] In a further technical solution, the electric heating plate is controlled by a solid-state relay, and the solid-state relay is connected to the control unit.

[0013] In a further technical solution, the high-pressure pump is controlled by a motor drive controller, which is connected to a control unit.

[0014] In a further technical solution, the electromagnetic control valve is connected to the control unit.

[0015] In a further technical solution, the control unit communicates wirelessly with the remote control device.

[0016] The beneficial effects of this utility model are:

[0017] This invention can efficiently remove ice by heating and pressurizing the pure water inside the device. The nozzle design expands the de-icing operation range. The high-temperature and high-pressure water flow can quickly and effectively flush away the ice layer on the power lines, preventing the ice layer from causing equipment failure or line breakage and ensuring the stable operation of the power system.

[0018] This invention offers high safety by using pure water as the de-icing medium. Furthermore, due to the high resistance of pure water, it can be used safely in energized environments. If de-icing is required during a power outage, a de-icing agent can be added to the pure water to enhance the de-icing effect.

[0019] This invention enables real-time monitoring of temperature and pressure through a control unit, and automatically controls the operation of the electric heating plate and high-pressure pump to ensure stable equipment operation.

[0020] Transmission lines prone to icing are mostly located in high mountains or remote areas. This invention can be carried to the work site by a heavy-duty drone or helicopter, adapting to different operational needs and environmental conditions. It is easy to operate and reduces the complexity and danger of manual operation. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, this utility model embodiment provides a power transmission line de-icing device based on high-temperature and high-pressure water flow, including a housing 1, which is hollow. A hollow high-temperature and high-pressure container 2 is disposed inside the housing 1. A water inlet 3 is disposed at the top of the high-temperature and high-pressure container 2, and a water outlet is disposed at the bottom of one side. The water outlet is connected to a spray structure through an electromagnetic control valve 6. An electric heating plate 4 is disposed close to the bottom of the high-temperature and high-pressure container 2 and is connected to a power source. A high-pressure pump 5 is disposed between the housing 1 and the high-temperature and high-pressure container 2, and the high-pressure pump 5 is connected to the high-temperature and high-pressure container 2 through a pipeline.

[0028] In this embodiment, the shell 1 has an overall cylindrical structure and is made of aluminum alloy or carbon fiber composite material, which can protect the internal components and avoid mechanical damage during transportation or operation. The inner wall of the shell is equipped with heat insulation material (a heat insulation layer is set, using materials such as ceramic fiber or aerogel) to maintain the water temperature inside the high-temperature and high-pressure container and reduce energy loss. The shell also provides mounting bases for various internal components, such as the high-temperature and high-pressure container, high-pressure pump, electric heating plate, etc., to ensure the stable operation of each component. When working with electricity, the shell material has insulation properties to prevent leakage or short circuit.

[0029] The shell 1 has an opening on one side of its top, opposite the water inlet 3 of the high-temperature and high-pressure container 2; a mounting structure is detachably installed at the top center, allowing it to be carried by a heavy-duty drone or helicopter; a accommodating compartment is located on the other side of the top of the shell 1, housing the control unit and battery unit. Specifically, when using a heavy-duty drone, the mounting structure can be adapted to the drone's existing equipment to maintain a secure mounting, ensuring the stability of the device and drone during water spraying; when using a helicopter, the device can be directly fixed to a base inside the helicopter's cabin facing the power line to ensure stability. The de-icing device can be carried by a heavy-duty drone or helicopter. The RTK positioning device on the drone or helicopter is used to determine the device's location information. The power line's location information can be obtained through existing lidar scanning data. Operators can compare and determine the working distance using a handheld terminal. After reaching the designated location, the control unit can be remotely controlled via a remote controller.

[0030] Furthermore, the mounting structure is a quick-release hoisting frame, consisting of four intersecting metal beams (such as aviation aluminum alloy beams) forming a "well" shaped frame. Connection holes are pre-drilled at the intersections and corresponding positions on the top of the casing 1, allowing the mounting structure to be bolted to the top of the device. Lifting rings are installed at the four corners of the frame, allowing direct attachment of the drone's slings or hooks. To prevent the lifting rings from detaching and the device from accidentally falling, spring locking plates are added to the inside of the lifting rings to prevent accidental detachment.

[0031] Furthermore, the battery unit is connected to the control unit, electric heating plate 4, high-pressure pump 5, and solenoid control valve 6 via wires to provide power to each component. An external power interface 7 is located on the lower side of one side of the housing 1. The power interface is internally connected to each internal component via wires and externally connected to an external power source to provide power to each component, namely the control unit, electric heating plate 4, high-pressure pump 5, and solenoid control valve 6. In other words, each component can be powered by either an external power source or by the device's own battery.

[0032] There is an annular gap between the side wall of the shell 1 and the high-temperature and high-pressure container 2. The wires are arranged along the side wall of the shell 1. The wires are high-temperature resistant wires and are wrapped and protected by high-temperature resistant insulating sleeves.

[0033] Furthermore, the control unit is implemented using a control chip, such as the STM32 series chip, which integrates a wireless communication module and boasts powerful performance. The specific model of the control chip can be selected according to the actual situation, and no specific limitation is made here.

[0034] In this embodiment, the high-temperature and high-pressure container 2 has a cylindrical structure that is compatible with the shell 1. A container support is provided at the bottom of the shell 1 to firmly fix the high-temperature and high-pressure container 2.

[0035] The outlet of the high-temperature and high-pressure vessel 2 is also equipped with a temperature sensor and a pressure sensor, which communicate with the control unit through a wireless communication module to transmit the real-time collected water temperature and pressure to the control unit for real-time monitoring of water temperature and pressure.

[0036] Both the temperature and pressure sensors are high-temperature resistant and high-precision devices. The temperature sensor can be either DS18B20 or PT100, and the pressure sensor can be either MPX5700 or MPS20N0040D-S. The wireless communication module uses Bluetooth. The models of these components can be flexibly selected according to actual needs and are not specifically limited.

[0037] An electric heating plate 4 is attached tightly to the bottom of the high-temperature and high-pressure container 2 and secured with clips or bolts. Insulation material is added between the electric heating plate 4 and the shell 1 to prevent heat loss and external overheating. The electric heating plate 4 is powered by a battery or external power source and heats the working water, i.e., the pure water inside the high-temperature and high-pressure container 2. A temperature sensor collects the water temperature in real time and transmits it to the control unit. The control unit compares the real-time water temperature with a set temperature threshold. If the real-time water temperature reaches the set temperature threshold, the control unit sends a control command to a solid-state relay to stop the electric heating plate 4 from heating.

[0038] Furthermore, the output terminal of the solid-state relay is connected to the electric heating plate 4. When the output terminal of the solid-state relay is turned on or off, the circuit of the electric heating plate 4 will turn on or off, controlling whether the electric heating plate 4 is powered on and working. The control unit controls the input terminal of the solid-state relay through a control signal. Specifically, the control unit determines whether the set temperature threshold has been reached based on the real-time water temperature feedback from the temperature sensor and through its built-in comparison logic. When the water temperature reaches the set temperature threshold, the control unit sends a control signal to the input terminal of the solid-state relay. After receiving the control signal, the solid-state relay switches the circuit of the electric heating plate 4 through its internal electronic switching element. If the set temperature is reached, the solid-state relay will disconnect the circuit of the electric heating plate 4 and stop the electric heating plate 4 from heating.

[0039] A high-pressure pump 5 is fixedly installed in the annular gap between the shell 1 and the high-temperature and high-pressure vessel 2 to maintain water pressure. The high-pressure pump 5 is fixed inside the shell 1 by a shock-absorbing pad to reduce the impact of vibration. A pressure sensor collects water pressure in real time and transmits it to the control unit. The control unit compares the actual water pressure with the set pressure threshold. If the real-time water pressure reaches the set pressure threshold, the control unit sends a control command to the motor drive controller to stop the high-pressure pump 5 from continuing to pressurize.

[0040] Furthermore, the high-pressure pump 5 is typically driven by a motor. A motor drive controller is installed to control the motor inside the high-pressure pump 5. The motor drive controller is connected to the control unit via a communication protocol and can send a stop signal. When the control unit determines through the pressure sensor that the real-time water pressure has reached the set pressure threshold, the control unit sends a stop pressurization signal to the motor drive controller. This signal causes the motor drive controller to cut off the motor power supply or reduce the motor speed to zero, thereby stopping the pressurization operation of the high-pressure pump 5.

[0041] In some implementations, the power transmission line de-icing device is also equipped with a temperature and pressure tiered control system. Different operating distances correspond to different temperature and pressure thresholds, and heating stops when these values ​​are reached. Specifically, a knob is installed on the outer wall of the housing, with settings for different levels and corresponding temperature and pressure thresholds. These thresholds are stored in the control unit. Preferably, the knob can be set to three levels, corresponding to level one, level two, and level three. The temperature and pressure thresholds for each level are set according to actual conditions and are not specifically limited.

[0042] The knob (rotary switch) is connected to the GPIO pin of the control unit via a signal line. When the knob is rotated to the corresponding position, the control unit reads the position signal (e.g., 00 = level 1, 01 = level 2, 10 = level 3) and retrieves the corresponding threshold value. Based on the corresponding threshold value, temperature and pressure control are achieved.

[0043] In some implementations, the high-pressure pump 5 can be either a plunger pump or a centrifugal pump to pressurize the water.

[0044] High-temperature and high-pressure containers 2 are typically made of stainless steel or composite carbon fiber and can withstand high-temperature and high-pressure environments.

[0045] When performing de-icing operations while the system is powered on, pure water is placed inside the high-temperature, high-pressure container 2 for de-icing. Pure water has a high resistance value, ensuring operational safety. When performing de-icing operations while the system is powered off, a de-icing agent can be added to the water in the unit to enhance the de-icing effect.

[0046] In this embodiment, the spray structure includes a spray pipe 8 and a nozzle 9 connected to the end of the spray pipe 8. The head of the spray pipe 8 is connected to the outlet of the high-temperature and high-pressure container 2. When the control unit controls the electromagnetic control valve 6 to open, the high-temperature and high-pressure water in the device will be sprayed out, using the impact force and temperature of the water flow to perform the ice-melting operation.

[0047] The electromagnetic control valve 6 is connected to the control unit, which controls the electromagnetic control valve 6 via a GPIO interface and communicates wirelessly with the remote control device via a wireless communication module. After a heavy-duty drone or helicopter carries the power line de-icing device to the work location, the operator controls the electromagnetic control valve 6 to open or close via a remote control. When the electromagnetic control valve 6 opens, it releases a high-temperature, high-pressure water flow to melt the ice. Specifically, after the device reaches the set working distance, the remote control device sends an opening or closing command to the control unit via its built-in wireless communication module (Bluetooth module). Upon receiving the opening command, the control unit checks if the current water temperature and pressure have reached the set temperature and pressure thresholds. If both the temperature and pressure reach the thresholds, the control unit outputs an opening control signal to the electromagnetic control valve 6, causing it to open. Similarly, upon receiving a closing command, the control unit directly outputs a closing command to the electromagnetic control valve 6, causing it to close.

[0048] In some implementations, the nozzle is equipped with a variety of different water flow nozzles, and the appropriate water flow nozzle can be selected as needed.

[0049] like Figure 3 As shown, the control circuit of the solenoid valve shows that the first power supply terminal is connected to the first end of the first resistor R1. The second end of the first resistor R1 is connected to the normally open contact of the pressure switch, the first end of the capacitor C, and the first end of the second resistor R2. The normally open contact of the pressure switch is connected in series with the normally open contact of the temperature switch. The normally open contact of the temperature switch is grounded, and the second end of the capacitor C is grounded. The first end of the second resistor R2 is connected to the NOT gate, and the second end is connected to the base of the transistor. The emitter of the transistor is grounded, and the collector of the transistor is connected to the second end of the relay J. The first end of the relay J is connected to the second power supply terminal. The second end of the relay J is also connected to the positive terminal of the freewheeling diode D. The negative terminal of the diode is connected to the second power supply terminal and the normally open contact J of the relay J, and is also grounded through the connection of the solenoid control valve 6.

[0050] When both temperature and pressure reach the set thresholds, the corresponding temperature and pressure switches change from "open" to "closed." At this time, the input of the NOT gate is low and the output is high, which turns on the transistor, energizes the coil of relay J, and causes its normally open contact J to close. The solenoid valve then opens. When the temperature and pressure do not reach the set values, the control process is the reverse of the above process.

[0051] Detailed explanation of working principle:

[0052] In the de-icing device, an electric heating plate 4 heats the pure water in the high-temperature, high-pressure container 2. The control unit monitors the water temperature in real time via a temperature sensor and compares it with a set temperature threshold. Once the water temperature reaches the set temperature and pressure, the control unit stops heating via a solid-state relay. When the water temperature and pressure reach the set threshold, operators arrive at the designated work location via helicopter or a heavy-duty drone. The operator controls the opening and closing of the electromagnetic control valve 6 via a remote control. The electromagnetic control valve 6 opens, and the high-temperature, high-pressure water is sprayed out through the nozzle 8, using the impact force and heat of the water flow to melt the ice layer on the power lines. Simultaneously, during the operation, the high-pressure pump 5, driven by a motor, pressurizes the pure water in the high-temperature, high-pressure container 2. A pressure sensor monitors the water pressure in real time and compares it with a set pressure threshold to maintain the water flow pressure. The electric heating plate 4 can be heated by a battery pack to maintain the water flow temperature as much as possible; the temperature does not need to be fully maintained at the temperature threshold during spraying.

[0053] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
