Description

Technical Field

[0001] This utility model relates to the field of ice-melting equipment technology, specifically to a lightweight DC ice-melting power supply. Background Technology

[0002] High-voltage transmission lines are a core component of power transmission and play a vital role in the power system. In southern my country, low winter temperatures, abundant rainfall, and high humidity make transmission lines prone to icing. If ice accumulation is not removed promptly, exceeding the permissible ice thickness can cause incalculable damage to the power system.

[0003] Currently, cable de-icing methods mainly include AC short-circuit current de-icing and DC current de-icing. AC short-circuit current de-icing is a complex and time-consuming operation with low efficiency. DC current de-icing is more practical than AC current de-icing, but the widely used DC de-icing equipment is large and can only be transported by large vehicles, resulting in poor mobility and difficulty in reaching mountainous or other terrain-challenged areas for de-icing operations. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a lightweight DC de-icing power supply, solving the problem of existing equipment being bulky and inconvenient to transport and move.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a lightweight DC ice-melting power supply, comprising:

[0007] The storage battery is fixed inside the unit frame and electrically connected to the rotor generator module via cables;

[0008] The switch module is fixed on the outer wall of the unit frame and is electrically connected to the integrated controller fixed inside the unit frame. The integrated controller is electrically connected to the battery and the rotor generator module.

[0009] The unit frame has a display screen on its outer wall near the switch module, and casters are installed at the bottom of the unit frame.

[0010] Preferably, the rotor power generation module includes a rotor starter and a rotor generator, wherein the rotor starter is used to start the rotor generator; both the rotor starter and the rotor generator are electrically connected to the battery via cables.

[0011] Preferably, the unit frame is equipped with a radiator for cooling the rotor generator.

[0012] Preferably, the heat sink comprises:

[0013] A heat dissipation grille is provided with a first flow channel inside the heat dissipation grille. The two ends of the first flow channel are connected to a second flow channel provided on the rotor generator through pipes to form a coolant circulation channel.

[0014] The fan is fixed on the side of the heat dissipation grille near the rotor generator and is used to drive airflow toward the heat dissipation grille.

[0015] Preferably, the rotor generator is equipped with a water pump, and the inlet and outlet of the water pump are connected to the coolant circulation channel.

[0016] Preferably, a first pulley is fixed on the shaft of the water pump, and a second pulley is fixed on the shaft of the rotor generator, with the first pulley and the second pulley being driven by a synchronous belt.

[0017] Preferably, the exhaust pipe end of the rotor generator is provided with a muffler, which is fixed to the unit frame by a clamp.

[0018] Preferably, an air filter is provided at the end of the air intake pipe of the rotor generator.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model integrates all major components such as the rotor generator module, battery, and integrated controller into the same unit frame. The rotor generator has high power density, small size, and light weight.

The casters at the bottom of the unit frame allow the entire device to be easily moved and transported as a whole unit, greatly improving deployment speed and flexibility, and making it particularly suitable for meeting the de-icing needs of different locations.

[0023] The radiator of this invention adopts a forced circulation coolant circulation system and fan-assisted heat dissipation, which can effectively remove the large amount of heat generated by the rotor generator, prevent the equipment from overheating and shutting down, and ensure stable operation in working conditions such as ice melting that require long-term high power output; the water pump is directly driven by the generator main shaft through a synchronous belt, without the need for additional power to drive the water pump, which saves energy, reduces potential electrical fault points, and improves the mechanical reliability of the system.

[0024] The silencer designed in this invention significantly reduces the exhaust noise generated during the operation of the rotor generator, making it more suitable for use near residential areas or in locations with noise restrictions. The shock absorber also helps reduce mechanical vibration noise. Attached Figure Description

[0036] Example 1

[0037] like Figures 1 to 7 As shown, Embodiment 1 of this utility model provides a lightweight DC de-icing power supply, including a unit frame 9, a rotor generator module 1, a battery 10, and a control module. The unit frame 9 is made of steel and includes a cubic frame with a bottom plate, a top plate, and four side plates fixed to it by bolts. Four universal wheels 13 with locking function are installed at the bottom of the unit frame 9 to facilitate equipment movement and fixation. A partition 17 is installed at the bottom of the inner cavity of the unit frame 9 through rubber shock absorbers 14, and the rotor generator module 1 is fixed to the partition 17 by bolts. The rubber shock absorbers 14 can significantly reduce vibration transmission. A 20mm gap is maintained between the partition 17 and the side wall to avoid resonance transmission. An oil tank 2 is fixed on the upper side of the inner cavity of the unit frame 9. The oil tank 2 is connected to an oil pump 5 through a pipe, and the oil pump 5 can deliver fuel to the oil supply line of the rotor generator module 1.

[0038] The control module includes a comprehensive controller 11, a display screen 7, and a switch module 8. The battery 10 is fixed to the bottom corner of the frame and connected to the rotor generator module 1 and the comprehensive controller 11 via a flame-retardant cable. The display screen 7 is fixed to the side panel, and the switch module 8 is fixed to the side panel below the display. Both the display and the switch module 8 are electrically connected to the comprehensive controller 11. The display screen 7 can display the output voltage, current, and equipment status parameters in real time. The busbar 12 is fixed to the side panel below the oil tank 2 and is electrically connected to the comprehensive controller 11. The lightweight DC de-icing power supply supplies power externally through the busbar 12. Each de-icing power supply is equipped with two busbars 12 for parallel and series connection, respectively, which can be replaced by the user before use as needed. All busbar 12 outputs have short connectors for positive and long connectors for negative. The connectors on the busbar 12 are designed to prevent incorrect insertion, effectively preventing users from mis-inserting the connectors.

[0039] The rotor generator module 1 includes a rotor starter and a rotor generator. The rotor starter is powered by the battery 10 and is used to start the rotor generator. After the rotor generator starts successfully, it continuously generates electricity and stores the electricity in the battery 10. The switch module 8 can control the power output of the battery 10 through the integrated controller 11, and use it to output the power to the ice melting equipment through the busbar 12.

[0040] The casters 13 at the bottom of the unit frame 9 make this utility model easy to move, and the side plates on both sides are also equipped with handles 15 to facilitate users to lift and move it.

[0041] Example 2

[0042] Based on Embodiment 1, Embodiment 2 further optimizes the heat dissipation system by adding a radiator 3 within the unit frame 9, comprising an aluminum heat dissipation grille 32 and an axial flow fan 31. The heat dissipation grille 32 has a serpentine first flow channel inside, which connects to a second flow channel inside the rotor generator housing via a high-temperature resistant hose, forming a closed coolant circulation loop. The fan 31 is fixed to the side of the heat dissipation grille 32 facing away from the generator, forcing airflow through the fins on the heat dissipation grille 32 to enhance heat dissipation. An exhaust vent is provided on the side plate near the heat dissipation grille 32 to prevent obstructed airflow to the fan 31.

[0043] A water pump 18 is fixed to the housing of the rotor generator. The inlet of the water pump 18 is connected to the outlet of the second flow channel, and the outlet is connected to the inlet of the first flow channel. To achieve power-free drive, one end of the shaft of the water pump 18 is fixedly connected to a first pulley, and a second pulley is installed on the output shaft of the rotor generator. The two are driven by a polyurethane synchronous belt 19. In this way, the residual kinetic energy of the generator can be used to drive the coolant to circulate in the circulation loop, reducing additional energy consumption.

[0044] Example 3

[0045] Based on Embodiments 1 and 2, this invention adds a multi-stage air filter 6 to the intake pipe end of the rotor generator to prevent dust particles in the air from entering the cylinder of the rotor generator. A composite muffler 4 is connected to the end of the exhaust pipe of the rotor generator. The muffler 4 is fixed to the side plate by a stainless steel clamp 16, which can effectively reduce the exhaust noise of the rotor generator.

[0046] During operation, the operator controls the power supply through the switch module 8. After the integrated controller 11 is powered on, various status information, operating information, and alarm information are displayed on the display screen 7 for the operator to read. During operation, the integrated controller 11 reads the information of each component and controls the rotor generator module 1 to operate, providing power to the ice melting equipment.

[0047] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
