Since the device shell 10 is internally provided with the water storage device 5, the problem of needing to separately provide a water source when using the ice removing device can be overcome. Similarly, the water storage device 5 can also not be arranged in the device shell 10, but a water inlet can be arranged on the device shell 10, and water in an external water source can be conveyed to the water pump 2 through the water inlet.

[0034] The heater 1 comprises a heater shell 11 and a storage tank 12 storing molten salt, the inside of the heater shell 11 is a storage tank installation cavity, the middle of the storage tank installation cavity is fixedly provided with the storage tank 12, the inner wall of the heater shell 11 and the outer wall of the storage tank 12 form a heating cavity, and the heating cavity comprises a first heating cavity 13 and a second heating cavity 14 which are independent of each other.

[0035] The gas outlet of the first heating cavity 13 is communicated with the gas inlet of the flow mixer 4, the liquid inlet of the first heating cavity 13 is communicated with the water outlet of the water pump 2, and the water inlet of the water pump 2 is communicated with the water outlet of the water storage device 5.

[0036] The gas outlet of the second heating cavity 14 is communicated with the gas inlet of the flow mixer 4, the gas inlet of the second heating cavity 14 is communicated with the gas outlet of the fan 3, the gas inlet of the fan 3 is communicated with the atmosphere, and the flow mixer 4 is provided with a nozzle 41, the gas inlet of the nozzle 41 is communicated with the gas outlet of the flow mixer 4, and the gas outlet of the nozzle 41 is located outside the device shell 10. The flow mixer 4 is used for mixing the fluid entering the inside of the flow mixer 4 uniformly and then spraying the fluid from the gas outlet.

[0037] In the above implementation manner, the molten salt has the advantages of high working temperature, wide use temperature range, strong heat transfer capacity, small system pressure, good economy and the like, and the molten salt energy storage can be applied to various energy storage application scenes. The heater shell 11 can be made of a heat insulation material to avoid heating other equipment in the device shell 10 and also to reduce heat loss of the molten salt in the storage tank 12. When deicing the power transmission line, the water pump 2 is started, the water pumped out of the water pump 2 absorbs the heat of the molten salt in the storage tank 12 to become high-temperature steam after entering the first heating cavity 13, the high-temperature steam is sprayed from the gas outlet after passing through the flow mixer 4; the fan 3 is started, the air output by the fan 3 absorbs the heat of the molten salt in the storage tank 12 to become hot air after passing through the second heating cavity 14, the hot air is sprayed from the gas outlet after passing through the flow mixer 4; and the water pump 2 and the fan 3 are started at the same time, so that the high-temperature steam and the hot air are mixed through the flow mixer 4 and then sprayed through the nozzle 41.

[0038] The flow distributor 6 is further arranged between the gas inlet of the second heating cavity 14 and the gas outlet of the fan 3, the gas inlet of the flow distributor 6 is communicated with the gas outlet of the fan 3 through the first pipeline 61, one gas outlet of the flow distributor 6 is communicated with the gas inlet of the second heating cavity 14 through the second pipeline 62, and the other gas outlet of the flow distributor 6 is communicated with the gas inlet of the flow mixer 4 through the third pipeline 63.

[0039] In the above implementation, the air blown by the fan 3 enters the flow distributor 6 through the first pipeline 61, the flow distributor 6 has two air outlets, and the flow distributor 6 can distribute the air flow of the two air outlets to adjust the flow of the natural wind and the hot air entering the mixing device 4. By changing the flow of the air entering the first heating cavity 13 and the flow of the air entering the second heating cavity 14 through the flow distributor 6, the proportion of the hot air and the natural wind entering the mixing device 4 is adjusted, and the temperature of the air blown from the mixing device 4 is changed.

[0040] The flow distributor 6 can be controlled according to the specific ice removal mode selected by the user.

At this time, the water pump 2 can be selected to be turned on or not turned on, when the water pump 2 is not turned on, the ice removal device only provides natural wind to the outside, and when the water pump 2 is turned on, the water output by the water pump 2 is heated to high-temperature steam by absorbing the heat of the molten salt in the storage tank 12 after passing through the first heating cavity 13, and the high-temperature steam enters the mixing device 4 and mixes with the natural wind, and the ice removal device provides mixed high-temperature steam and natural wind to the outside. For the ice on the power transmission line that is difficult to remove, all the air output by the fan 3 can be controlled by the flow distributor 6 to enter the second heating cavity 14 through the second pipeline 62, and the air is heated to hot air by absorbing the heat of the molten salt in the storage tank 12 after passing through the second heating cavity 14, and then enters the mixing device 4; at the same time, the water pump 2 is turned on to deliver water to the first heating cavity 13, and the water is heated to high-temperature steam in the first heating cavity 13 and then enters the high-temperature steam mixing device 4 to mix with the hot air, and the ice removal device provides mixed high-temperature steam and hot air to the outside, which can quickly melt the ice that is difficult to remove and make it fall off from the power transmission line.

[0041] The ice removal device further comprises a pulser 8, one pulse signal output end of the pulser 8 is connected with the control end of the flow distributor 6, and the other pulse signal output end of the pulser 8 is connected with the control end of the fan 3, and the pulser 8 is arranged in the inside of the device housing 10.

[0042] The ice removal device further comprises a controller 7, one control signal output end of the controller 7 is connected with the control end of the water pump 2, and the other control signal output end of the controller 7 is connected with the control end of the pulser 8, and the controller 7 is arranged in the inside of the device housing 10.

[0043] In the above implementation manner, the controller 7 is configured to control the pulser 8 to output the pulse signal. One pulse signal output end of the pulser 8 is configured to output the pulse signal and control the gas flow of the two gas outlets of the flow distributor 6 through the pulse signal, so as to change the flow of the gas in the second pipeline 62 and the third pipeline 63. Compared with continuously outputting hot air, the use of the pulse control manner can reduce the heat exchange of the hot molten salt as much as possible under the premise of ensuring high deicing efficiency, that is, a little loss of pulse current is exchanged for more loss of heat of the hot molten salt, so that the persistence of the use of the portable deicing device can be further increased. Another pulse signal output end of the pulser 8 is configured to output the pulse signal and control the start-stop and rotating speed of the fan 3 through the pulse signal.

[0044] The deicing device further comprises a battery 9, the battery 9 is arranged in the inside of the device shell 10, and the battery 9 supplies power for the water pump 2, the fan 3, the controller 7 and the pulser 8.

[0045] In the above implementation manner, the battery 9 can be a lithium battery or other storage battery, and other self-provided power sources can also be used to supply power for the deicing device.

[0046] The gas outlet of the first heating cavity 13 is connected with the gas inlet of the flow mixer 4 through the fourth pipeline 15, and the valve 16 is arranged on the fourth pipeline 15. The speed of the high-temperature steam can be controlled by adjusting the opening degree of the valve 16.

[0047] The storage tank 12 is detachably arranged in the heater 1, and after being used for a period of time, the storage tank 12 can be disassembled and replaced. The inside of the heater 1 is provided with a base 17 for supporting and fixing the storage tank 12, and the base 17 is provided with an electric heating device which can be connected with an external power source.

[0048] In the above implementation manner, the electric heating device heats the whole storage tank 12 after being connected with the external power source, so that the molten salt in the storage tank 12 absorbs and stores heat. The electric heating device can be a resistance wire, and the resistance wire is attached to the storage tank 12. When the resistance wire is electrified, heat is generated to heat the storage tank 12 and the molten salt in the inside of the storage tank 12. The electric heating device can also be an electromagnetic induction type heater, and in this case, the storage tank 12 is made of a metal material with a high melting point, for example, 304 stainless steel. The electromagnetic induction type heater comprises a high-frequency coil. When high-frequency alternating current is input into the high-frequency coil, Joule heat makes the temperature of the metal tank body of the storage tank 12 rise, and the molten salt in the inside of the storage tank 12 is heated. The reheating of the cooled storage tank 12 through the base 17 can avoid repeatedly disassembling and assembling the device shell 10 and the heater shell 11 due to the replacement of the storage tank 12, and the use of the deicing device is more convenient.

[0049] In addition, the present application further provides a use method of the deicing device, and the use method of the deicing device comprises:

[0050] When deicing the transmission line, the water pump 2 and the air blower 3 are turned on to respectively heat the water in the first heating cavity 13 and the air in the second heating cavity 14 by the heat of the molten salt in the storage tank 12, so that the high-temperature steam and the hot air are mixed in the mixing device 4 and sprayed out.

[0051] When deicing the transmission line, the flow distributor 6 and the pulser 8 are turned on, and the pulser 8 is controlled by the controller 7 to send a pulse signal to control the flow distributor 6 to adjust the flow of the hot air and the natural air sprayed out of the mixing device 4.

[0052] The deicing device can provide multiple deicing modes for the operator to select, including:

[0053] a. Natural air deicing: The air blower 3 is turned on, and the flow distributor 6 is controlled to make the air outlet of the air blower 3 not communicate with the air inlet of the second heating cavity 14, and the air outlet of the air blower 3 communicate with the air inlet of the mixing device 4, at this time the air jet port on the mixing device 4 sprays natural air (i.e. unheated air);

[0054] b. Hot air deicing: The air blower 3 is turned on, and the flow distributor 6 is controlled to make the air outlet of the air blower 3 communicate with the air inlet of the second heating cavity 14, at this time the air jet port on the mixing device 4 sprays hot air;

[0055] c. Alternating natural air and hot air deicing: The air blower 3 is turned on, and the flow distributor 6 is controlled to make the air outlet of the air blower 3 alternately communicate with the air inlet of the second heating cavity 14 and the air inlet of the mixing device 4, at this time the air jet port on the mixing device 4 alternately sprays natural air and hot air;

[0056] d. High-temperature steam deicing: The water pump 2 is turned on, and the water pumped out of the water pump 2 is heated and gasified to form high-temperature steam after flowing into the second heating cavity 14, at this time the air jet port on the mixing device 4 sprays high-temperature steam;

[0057] e. High-temperature steam mixed with natural air deicing: The water pump 2 and the air blower 3 are turned on, and the flow distributor 6 is controlled to make the air outlet of the air blower 3 not communicate with the air inlet of the second heating cavity 14, and the air outlet of the air blower 3 communicate with the air inlet of the mixing device 4, at this time the air jet port on the mixing device 4 sprays natural air mixed with high-temperature steam;

[0058] f. High-temperature steam mixed with hot air deicing: The water pump 2 and the air blower 3 are turned on, and the flow distributor 6 is controlled to make the air outlet of the air blower 3 communicate with the air inlet of the second heating cavity 14, at this time the air jet port on the mixing device 4 sprays hot air mixed with high-temperature steam;

[0059] g. High-temperature steam mixed with natural wind and hot wind for deicing: the water pump 2 and the fan 3 are turned on, and the flow distributor 6 is controlled to alternately connect the air outlet of the fan 3 with the air inlet of the second heating cavity 14 and the air inlet of the flow mixer 4, at this time the air jet nozzles on the flow mixer 4 alternately spray natural wind mixed with high-temperature steam and hot wind mixed with high-temperature steam.

[0060] The above deicing mode can be realized by setting a fixed control program in the controller 7.

[0061] In actual deicing operation, the ice attached to the power transmission line can be ice debris and ice blocks that are easy to remove, or ice blocks and ice layers that are difficult to remove and are firmly condensed on the line, and it is difficult for the operator to directly determine whether the ice blocks attached to the power transmission line are easy to remove. Therefore, the following steps can be performed during deicing:

[0062] Step one: the air jet nozzles 41 on the flow mixer 4 are aimed at the power transmission line, the fan 3 is turned on, and the flow distributor 6 is controlled to connect the air outlet of the fan 3 with the air inlet of the second heating cavity 14 and not connect the air outlet of the fan 3 with the air inlet of the flow mixer 4, at this time the flow mixer 4 continuously sprays natural wind to the power transmission line, and after 5-10 minutes, it is observed whether the ice blocks on the power transmission line fall off:

[0063] If the ice blocks on the power transmission line gradually fall off, it indicates that the ice attached to the power transmission line is ice debris and ice blocks that are easy to remove, at this time step two is entered to quickly deice the power transmission line; if the ice blocks on the power transmission line do not fall off, it indicates that the ice attached to the power transmission line is ice blocks or ice layers that are difficult to remove, at this time step three is entered to use high-temperature steam to melt the ice blocks that are difficult to remove.

[0064] Step two:

[0065] The fan 3 is kept on, and the flow distributor 6 is controlled to act by the pulse generator 8 to alternately connect the air outlet of the fan 3 with the air inlet of the second heating cavity 14 and the air inlet of the flow mixer 4, at this time the air jet nozzles 41 on the flow mixer 4 alternately spray hot wind and natural wind to the power transmission line.

[0066] Step three:

[0067] The fan 3 is kept on, the water pump 2 is turned on, and the flow distributor 6 is controlled to act by the pulse generator 8 to alternately connect the air outlet of the fan 3 with the air inlet of the second heating cavity 14 and the air inlet of the flow mixer 4, at this time the air jet nozzles 41 on the flow mixer 4 alternately spray natural wind mixed with high-temperature steam and hot wind mixed with high-temperature steam to the power transmission line.

[0068] Through the above steps, ice debris, ice blocks, and stubborn ice layers on the power transmission line can be quickly and efficiently removed.

[0069] The principles of the present application are described as follows:

[0070] By setting the heater 1, water pump 2, fan 3 and mixer 4 in the shell 10, and setting the storage tank 12 for storing molten salt in the heater shell 11 of the heater 1, setting the first cavity and the second cavity outside the storage tank 12, when deicing the power line, the water output by the water pump 2 absorbs the heat of the molten salt in the storage tank 12 after passing through the first heating cavity 13 and becomes high-temperature steam, the air output by the fan 3 absorbs the heat of the molten salt in the storage tank 12 after passing through the second heating cavity 14 and becomes hot air, and the high-temperature steam and the hot air are mixed by the mixer 4 and sprayed through the nozzle 41.
