As used in this description, the terms "may" and "can" include any one of the possible combinations of the terms and / or the associated items.

[0040] The utility model discloses a novel mobile lighting and power supply dual-purpose lighthouse.

[0043] The battery pack is used for supplying power to the LED lamp 30 and supplying power to the outside, the alternating current input interface 11 is used for connecting alternating current, the direct current input interface 12 is used for connecting direct current, and the outer wall of the vehicle body 10 is provided with an alternating current output interface 13 and a direct current output interface 14 for supplying power to the outside in cooperation with the battery pack.

[0044] The main control board is used for converting the alternating current connected through the alternating current input interface 11 into direct current and charging the battery pack through the direct current, converting the direct current connected through the direct current input interface 12 into direct current after voltage conversion and charging the battery pack, and supplying power to the LED lamp 30 through voltage conversion of the direct current output by the battery pack.

[0045] The new mobile lighting and power dual-purpose light tower includes a vehicle body, a telescopic rod fixedly connected to the vehicle body, and an LED lamp installed at the top of the telescopic rod.

It can be seen that the battery pack is used to supply power to the LED lamp, so that the mobile lighting and power dual-purpose light tower can be applied to scenes far away from the city power supply. Further, by setting the AC input interface and the DC input interface, the user can select an AC power source or a DC power source to charge the battery pack according to actual needs, improving the convenience of battery pack charging. Further, the main control board can control the charging process and discharging process of the battery pack, improving the safety of the battery pack charging process. Further, by setting the AC output interface and the DC output interface, the new mobile lighting and power dual-purpose light tower can also be used as an emergency power supply and an industrial mobile power supply.

The inverter is used to convert the DC power output by the battery pack into AC power and output the AC power through the AC output interface 13. The main control board is further used to control the working state of the inverter.

[0047] It can be seen that the cooperation of the inverter and the AC output interface 13 enables the new mobile lighting and power dual-purpose light tower to output AC power, thereby supplying power to AC electrical equipment, making the application scenarios of the new mobile lighting and power dual-purpose light tower more diversified. By setting the DC output interface 14, the new mobile lighting and power dual-purpose light tower can meet the power supply needs of DC electrical equipment.

[0048] The side wall of the vehicle body 10 is provided with a heat dissipation window 15, and a plurality of dustproof plates 16 are installed on the heat dissipation window 15; the dustproof plate 16 comprises a first dustproof part 161 clamped with the side wall of the vehicle body 10, a second dustproof part 162 connected with the first dustproof part 161, and a third dustproof part 163 connected with the second dustproof part 162; the first dustproof part 161 is vertically arranged, the second dustproof part 162 extends downwardly and obliquely, and the third dustproof part 163 is vertically arranged; the top of the second dustproof part 162 is connected with the bottom of the first dustproof part 161, and the top of the third dustproof part 163 is connected with the bottom of the second dustproof part 162.

[0049] It should be noted that the plurality of dustproof plates 16 installed on the heat dissipation window 15 are arranged from top to bottom in sequence. The vertical spacing between adjacent dustproof plates 16 is less than the vertical length of a single dustproof plate 16, and because the first dustproof part 161 is vertically arranged, the second dustproof part 162 extends downwardly and obliquely, and the third dustproof part 163 is vertically arranged, it is difficult for dust from the outside to enter the interior of the vehicle body 10 through the heat dissipation window 15; and the heat inside the vehicle body 10 can be quickly dissipated through the gap between adjacent dustproof plates 16.

[0050] The vehicle body 10 is fixedly installed with an upper fixing part 17 and a lower fixing part 18, and the upper fixing part 17 is installed on the upper side of the lower fixing part 18; the lower fixing part 18 comprises a first fixing part 181 and a second fixing part 182 connected with the first fixing part 181, the first fixing part 181 is fixedly connected with the vehicle body 10, the second fixing part 182 is provided with a plug-in slot, and the bottom of the telescopic rod 20 is plugged into the second fixing part 182 through the plug-in slot; the upper fixing part 17 comprises a third fixing part 171 and a fourth fixing part 172 connected with the third fixing part 171, the third fixing part 171 is fixedly connected with the vehicle body 10, the third fixing part 171 is provided with a first limiting slot 1711 matched with the telescopic rod 20, and the fourth fixing part 172 is provided with a second limiting slot 1721 matched with the telescopic rod 20.

Through the cooperation of the second fixing part 182, the third fixing part 171 and the fourth fixing part 172, the telescopic rod 20 can be firmly fixed on the vehicle body 10.

[0053] As can be seen, through the cooperation of the fixing screw and the screw hole at the bottom of the telescopic rod 20, the telescopic rod 20 and the lower fixing part 18 can be firmly fixed together.

When the external photovoltaic system fails, the photovoltaic input circuit breaker 40 will immediately cut off the circuit, thereby protecting the new mobile lighting and power dual-purpose lighthouse. When the battery pack is charged by the external alternating current power supply, the alternating current input circuit breaker 50 can protect the battery pack from current overload, short circuit, ground fault and the like. When the external alternating current power supply fails, the alternating current input circuit breaker 50 will immediately cut off the circuit, thereby protecting the new mobile lighting and power dual-purpose lighthouse. When the battery pack supplies power to the external alternating current electrical equipment, the alternating current output circuit breaker 60 can protect the battery pack from current overload, short circuit, ground fault and the like. When the external alternating current electrical equipment fails, the alternating current output circuit breaker 60 will immediately cut off the circuit, thereby protecting the new mobile lighting and power dual-purpose lighthouse.

[0056] The outer wall of the vehicle body 10 is further provided with a backup battery interface 19, and the battery pack is used for being connected in parallel with an external battery through the backup battery interface 19. Through the backup battery interface 19, the battery pack can provide power supply for the new mobile lighting and power dual-purpose lighthouse after being connected in parallel with the external battery, so that the power supply of the new mobile lighting and power dual-purpose lighthouse is more secure.
