[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1 As shown, the utility model is a marine thin plate leveling device with a power-assisting device, comprising: a cooling system 1, a variable frequency power supply 2, a hand-push leveler 11, a relay switching unit 5, a main controller 6, and a power-assisting device 36; the variable frequency power supply 2 converts the power supply voltage into a current with a frequency matching the high-efficiency heating, and the main controller 6 can set the equipment parameters and control the operation of the equipment; the cooling system 1 is a closed-loop water cooling system, which removes the heat generated by the hand-push leveler 11 and the variable frequency power supply 2 during the leveling operation of the equipment through circulating cooling water, thereby dissipating heat for the entire equipment; the cooling system 1 is a closed-loop water cooling system, which removes the heat generated by the hand-push leveler 11 and the variable frequency power supply 2 during the leveling operation of the equipment through circulating cooling water, thereby dissipating heat for the entire equipment; The exhaust gas generated by the system 1 is input into the booster device 36 after being compressed by the exhaust gas recovery device and air to achieve booster leveling; the relay switching unit 5 is used for adaptive power factor compensation during the long-distance transmission of high-frequency and high-voltage electricity; the booster device 36 is arranged on the hand-push leveler 11, and its power source comes from the exhaust gas generated by the water cooler during the leveling operation: the gas collecting cover installed on the exhaust fan of the water cooler collects the gas generated by the exhaust fan, transports it to the air compressor 9 for compression, and then inputs it into the high-pressure sealed gas collecting tank 10, and then the high-pressure gas is input into the booster device 36 for booster leveling. The gas collecting cover is a conical gas collecting cover, which is detachably mounted on the outer circumference of the exhaust fan, and includes an exhaust pipe and an air outlet 14 connected to the screw air compressor 9.

[0027] The leveling equipment of the utility model is arranged in a container 3, which is convenient for storage and lifting and handling. The variable frequency power supply 2 converts the power supply voltage into a current of a frequency matching the efficient heating. The equipment parameters are set by the main controller 6, and no adjustment by the operator is required after the trial operation. The controller 6 can be used for ordinary operator control, such as phase switching (for cooling pump rotation) and fault display and reset settings. The cooling system 1 is a closed-loop water cooling system. The entire system is operated by condensing water circulation. The heat generated by the hand-push leveler 11 and the variable frequency power supply 2 during the operation of the system is taken out by circulating cooling water, and discharged from the system through the heat exchange component; it plays a heat dissipation function for the entire set of equipment.

[0028] The relay switching unit 5 is a system energy compensation component, which realizes the adaptive power factor compensation function during the long-distance transmission of high-frequency and high-voltage electricity, and realizes the plug-in conversion of two heaters. The two heaters include an automatic leveler 4 and a handheld leveler 11. The power cable and the water cable are integrated into a cable 7, which is wrapped with heat-resistant and wear-resistant materials. Cable 7 connects the entire set of hand-push levelers 11 to provide a power source for them. During the operation of the marine thin plate leveling equipment, a large amount of exhaust gas is generated. The exhaust fan is connected through the gas collection equipment to collect the waste gas into the high-pressure closed gas collection tank 10, and then discharged by the power assist device 36 to achieve the power assist effect.

[0029] Figure 2-A The utility model shown does not include some structures of the container and the water cooler, including: a conical gas collecting cover, a screw air compressor 9, a high-pressure sealed gas collecting tank 10, and a hand-push leveler 11. The conical gas collecting cover is used to collect the gas generated by the exhaust fan of the cooling system 1 of the electromagnetic induction leveling equipment, and discharge it through the plastic hose connected to the conical gas collecting cover, and the waste gas is transported to the screw air compressor 9 for air compression, and the compressed high-pressure gas is transported to the high-pressure sealed gas collecting tank 10. After the collection is completed, the high-pressure gas is transported to the hand-push leveler 11 to assist the leveling work.

[0030] Figure 2-BThe conical gas collecting cover is a schematic diagram of the structure. The conical gas collecting cover includes: a hanging handle 12, a hanging hook 15, and an exhaust pipe running through the inside of the gas collecting cover at the upper end of the gas collecting cover. An air outlet 14 is provided outside the exhaust pipe for connecting the hose of the screw air compressor 9. The bottom surface of the lower cover is surrounded by an annular side wall, and the upper cover is conical. The bottom surface of the annular side wall is sealed with the outer circumference of the container exhaust fan by using an annular sealing strip 13. The conical gas collecting cover is a gas collector with a shape similar to a cone. The annular sealing strip 13 separates the inside of the gas collecting cover from the outside world to achieve 100% collection of waste gas. The collected waste gas is discharged through the gas outlet 14 of the gas collecting cover. Two handles 12 are installed on the periphery of the lower end of the gas collecting cover for disassembly and assembly of the conical gas collecting cover. If the conical gas collecting cover is always installed at the exhaust port, it may cause high temperature to damage the internal parts and electronic components of the equipment, and may even cause equipment failure and failure. Excessive temperature will cause the performance of the equipment to decline, thereby affecting the leveling effect and work efficiency. The surface temperature of the equipment will rise, which may easily cause burns or discomfort to the operator. Excessive temperature will accelerate the wear and aging of the equipment and shorten the service life of the equipment. Therefore, when the conical gas collecting cover is not in use, it can be placed on the hanging hook 9 on the side wall of the container.

[0031] Figure 3-A , 3-B 3-C is a schematic diagram of the waste gas recovery device and its cross-sectional structure of the utility model. The waste gas recovery device includes a screw air compressor 9 and a high-pressure sealed gas collecting tank 10. The screw air compressor is placed above the high-pressure sealed gas collecting tank 10, and the two are fixed as a whole by screws. The screw air compressor includes a shell 25, a female rotor 23, a male rotor 24, and an engine 17. The engine 17 is connected to the cable 7 to provide an energy source. An air inlet 19 is left at the upper end of the outer shell, which is connected to the above-mentioned conical machine cover through a hose. The side exhaust port 18 is connected to the high-pressure sealed gas collecting tank intake valve 16 through a hard pipe. A pair of mutually meshing spiral male and female rotors are installed inside the shell, and both rotors have multiple concave teeth. The generator drives the male rotor 24 to drive the female rotor 23 to rotate. A transmission shaft that penetrates and moves is connected to one side of the shell. The transmission shaft forms an integrated structure with the spiral male rotor 24. The male rotor end is driven by the motor to mesh with the female rotor. The gap between the rotors and between the casing and the rotor is only 5 to 10 threads. The male and female rotors rotate in opposite directions to achieve the effect of compressed air volume. A tripod 22 is placed under the high-pressure sealed gas collecting tank 10, which can be stably placed on the working surface. It includes an air storage chamber 28, an air charging valve 16 and an air outlet valve 21. The air charging valve 16 is connected to the screw air compressor 9, and the air outlet valve 21 is connected to the power assist device 36 of the handheld leveler. The air storage chamber 28 is sealed and cannot be opened. The air storage chamber 28 and the shell 26 are both cylindrical, and the air storage chamber 28 and the shell 26 are filled with lightweight insulating solid foam material.

[0032] The utility model uses an air energy conversion system, in which a motor drives a screw air compressor 9, collects waste gas discharged by an exhaust fan, compresses the compressor 9 to generate high-pressure gas, enters the air storage chamber 28 through the air inlet valve 16 of a high-pressure sealed air collecting tank 10, and then enters the trolley-type leveler assisting device 36 through its air outlet valve 21. By using a high-pressure air storage tank, a contraction tube, and a screw air compressor to form an air path control system, the energy conversion efficiency and power of the air energy conversion system can be artificially controlled.

The power assist device 36 controls its operation and gas flow rate through the power control line 30. The high-pressure gas flows in through the air inlet pipe 31, which is placed inside the water-electricity integrated cable 7. The flow rate control valve 32 executes the instructions of the main control panel 34, and the device is discharged through the exhaust port after operation. The main control panel is provided with a wind speed adjustment control knob 33 for controlling the gas flow rate, thereby affecting the forward speed of the hand-push leveler.
