[0003] Chinese patent CN216767484U discloses a gas-fired power generation device, comprising: a bearing; a rotating shaft passing through the bearing, on which a turbine is coaxially fixed; a generator assembly including a magnetic rotor mounted on the rotating shaft and a stator sleeved outside the rotating shaft, the stator and the magnetic rotor being positionally matched; a gas inlet pipe communicating with the area between the bearing and the rotating shaft, and for supplying gas toward the turbine to drive the turbine to rotate; and a gas outlet pipe communicating with the area between the bearing and the rotating shaft, and for discharging the gas used to drive the turbine to rotate, capable of converting the pressure energy of the gas into electrical energy. However, this device and the prior art still have the following technical problems: 1. This device uses natural gas or high-pressure exhaust gas to drive a turbine to rotate, so that the magnetic rotor of the motor rotates relative to the stator of the motor, which can convert the pressure energy of the gas into electrical energy. However, it has not been applied to industrial inert gases commonly used in industrial production, and the related technical field is still a blank in the industry.

[0004] 2. The device supplies gas to the turbine through the gas inlet pipe to drive the turbine to rotate. The external gas required needs a stable supply source. However, common vaporizer devices are prone to icing due to frequent use during operation, and the ice layer at the top edge of the vaporizer is difficult to remove, which can easily disrupt the original stable gas supply.

[0022] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0023] In some embodiments, please refer to the accompanying drawings. Figures 1-6 A device for energy-saving power generation by utilizing the pressure drop of liquefied gas includes a base 1; It also includes a liquid storage tank 2, a vaporizer pressurization and gas supply mechanism 3, and a high-pressure gas output regulating mechanism 4; The vaporizer pressurization and gas supply mechanism 3 includes an ambient temperature vaporizer 31 and a top auxiliary de-icing component 32. The ambient temperature vaporizer 31 is fixedly connected to the upper end of the base 1, and the top auxiliary de-icing component 32 is installed on the upper end of the base 1. The high-pressure gas output regulating mechanism 4 includes a regulating component 41, a regulating valve 42, and an output component 43. Both the regulating component 41 and the output component 43 are mounted on the upper end of the base 1. The input end of the regulating component 41 is connected to the output end of the ambient temperature vaporizer 31, the output end of the regulating valve 42 is connected to the output end of the regulating component 41, and the output ends of both the regulating component 41 and the regulating valve 42 are connected to the input end of the output component 43.

[0024] In this invention, the liquefied gas in the liquid storage tank 2 is vaporized by the ambient air vaporizer 31 and transported to the regulating component 41. After the high-pressure gas is depressurized by the regulating component 41, it can be supplied to the outside and powered through the output component 43. The top auxiliary de-icing component 32 can effectively help remove the ice layer that is difficult to clean from the upper edge of the ambient air vaporizer 31 to ensure the stable operation of the ambient air vaporizer 31. The regulating valve 42 can ensure stable gas supply when the regulating component 41 is under maintenance.

[0025] Please see Figures 1-6 The top auxiliary de-icing component 32 includes a mounting bracket 321, a vacuum tube 324, and a tracking focusing component. The mounting bracket 321 is fixedly connected to the upper end of the base 1, multiple sets of vacuum tubes 324 are fixedly connected to the upper end of the mounting bracket 321, and two sets of tracking focusing components are installed at symmetrical positions at the top of the mounting bracket 321. The outer end of the vacuum tube 324 is coated with a selective absorption coating, and the inside is filled with heat-conducting oil. The tracking focusing assembly includes an arc-shaped focusing plate 322, a hydraulic cylinder 323, a rotating shaft 325, a connecting shaft 326, and ear plates 327. The rotating shaft 325 is rotatably connected to the upper end of the mounting bracket 321. The lower end of the arc-shaped focusing plate 322 is fixedly connected to the side end of the rotating shaft 325. The connecting shaft 326 is fixedly connected to the outer end of the arc-shaped focusing plate 322. Two pairs of ear plates 327 are fixedly connected to the side end of the mounting bracket 321. Two sets of hydraulic cylinders 323 are respectively hinged to the inner ends of the two pairs of ear plates 327. The output end of the hydraulic cylinder 323 is hinged to the side end of the connecting shaft 326. The two sets of hydraulic cylinders 323 that track the concentrator are automatically started and stopped by an external sunlight tracking device and controller.

[0026] In this invention, multiple sets of vacuum tubes 324 at the upper end of the mounting bracket 321 are used to absorb and store the heat of sunlight reflected by the tracking concentrator. The output end of the hydraulic cylinder 323, which is hinged to the inner end of the ear plate 327, drives the connecting shaft 326 to rotate around the rotating shaft 325, thereby causing the arc-shaped concentrator 322 to adjust its orientation according to the sun's height. This allows the top of the air-temperature vaporizer 31 to exchange heat under the heating of the vacuum tubes 324 even in environments with poor light, thereby assisting in the de-icing operation of the top edge of the air-temperature vaporizer 31. The solar tracking device is a mature existing technology, with the publication number CN205263662U. By inputting the latitude and longitude information of the location of the solar tracking device, the accurate direction of the sun can be calculated. Then, the hydraulic cylinder 323 is controlled by the drive controller to complete the flipping action of the arc-shaped concentrator 322. The two sets of tracking and concentrating components are used to absorb the heat of the sun at different times.

[0027] Please see Figures 1-2 The regulating component 41 includes an intake valve 411, an expander 412, and an exhaust valve 413.

The output end of the intake valve 411 is fixedly connected to the expansion end of the expander 412.

The generator 432 is fixedly connected to the upper end of the base 1. The detection end of the pressure sensor 431 is fixedly connected to the output end of the air outlet valve 413 and the output end of the regulating valve 42. The output ends of the air outlet valve 413 and the regulating valve 42 are fixedly connected to an external conveying pipeline. The input end of the generator 432 is fixedly connected to the boosting end of the air outlet valve 413.

[0028] In this utility model, by opening the inlet valve 411 and the outlet valve 413, the high-pressure gas vaporized by the ambient air vaporizer 31 is guided to the expansion end of the expander 412 to be depressurized and output. After being depressurized to the specified pressure, it is transported to the user's pipeline network through an external pipeline. When the high-pressure gas is depressurized in the expander 412, it will drive the generator 432 to run and generate electricity while driving the booster end of the expander 412 to do work. When the expander 412 needs maintenance, the inlet valve 411 and outlet valve 413 can be closed, and the regulating valve 42 of another passage can be opened. The high-pressure gas will be depressurized through the regulating valve 42 and flow directly to the external pipeline and to the user's gas supply end. In the external pipeline connected to the outlet valve 413 and the output end of the regulating valve 42, there is a pressure sensor 431 for real-time monitoring of the gas pressure supplied to the user.
