Description

Technical Field

[0001] This invention relates to the field of power machinery technology, specifically a novel power machine that integrates a closed-loop cycle of four energy sources: electrical energy, pneumatic energy, kinetic energy, and hydraulic energy, and employs a dual-power gas generation structure of an electric air pump and phase change expansion. It can be widely used in automobiles, large mining machinery, industrial plant power equipment, and other scenarios, replacing traditional internal combustion engines and single-power drive devices. This equipment is not a traditional dual-fuel hybrid combustion structure, and supports independent operation of a single energy source and dual-energy selection mode, belonging to the category of energy-saving and environmentally friendly power equipment technology. Background Technology

[0002] Currently, traditional fuel-powered equipment generally suffers from high energy consumption, significant emissions, and low energy utilization. Furthermore, conventional hybrid power equipment only achieves a simple combination of single or dual energy sources, resulting in a limited power supply mode, a lack of backup power sources, and insufficient operational stability. Meanwhile, existing pneumatic-hydraulic power devices generally lack a closed-loop energy recovery structure, with waste gas generated during braking and energy conversion being directly emitted, causing substantial energy waste. Additionally, the equipment's steering system has a complex structure and relatively high power loss.

[0003] To address the aforementioned issues, this invention integrates dual-power gas production, four-energy coupling conversion, and residual gas closed-loop recovery technologies into a single system. Multiple key technologies are combined into a unified inventive concept, eliminating the need for separate applications and effectively resolving existing technological deficiencies, thereby improving the energy efficiency and operational stability of the power unit. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing power equipment technology and provides a closed-loop coupled phase change expansion power machine that integrates electric energy, gas energy, kinetic energy, and hydraulic energy. It uses an electric air pump and phase change expansion gas production as dual independent power sources, with two independent operating modes that can be flexibly selected according to actual working conditions. It can be used in a single-fuel mode to meet small-scale working conditions, or it can operate independently of traditional fuels using phase change technology to achieve high-pressure gas energy storage, which drives the equipment after gas-liquid pressurization and hydraulic energy storage. At the same time, it is equipped with a waste gas closed-loop recovery system to achieve the effects of recycling four energy sources, energy saving and consumption reduction, stable power, and versatility in multiple scenarios. Multiple key technologies are integrated into a unified inventive concept, eliminating the need for separate applications.

[0005] The core of this power unit is an integrated structure featuring dual-power gas production, four-energy conversion, closed-loop drive, and waste gas recovery. It achieves closed-loop recycling of electrical energy, gas energy, kinetic energy, and hydraulic energy throughout the entire process, with no unnecessary energy loss. The specific structure and working principle are as follows:

[0006] This power unit is equipped with two independent and parallel gas-generating power sources, sharing a single gas storage tank. There is no need for two separate downstream mechanisms. The two power sources operate independently and can be selected for individual operation as needed, or they can form a dual-energy collaborative working mode depending on the operating conditions: an electric air pump, powered by electricity, compresses air to generate high-pressure gas, which is then delivered to the gas storage tank, converting electrical energy into gas energy. This can be used independently as a single energy source for small-scale operations. The phase change expansion gas-generating mechanism utilizes the principle of phase change expansion of the medium, generating high-pressure gas directly through volume expansion caused by changes in the physical state of the medium. This gas is simultaneously delivered to the gas storage tank, serving as an independent gas-generating power source that can operate independently of traditional fuels, relying solely on phase change technology. The high-pressure gas generated by both power sources is stored uniformly in the gas storage tank, which maintains a constant pressure of 8 standard atmospheres to ensure stable downstream power output.

[0007] The gas storage tank outputs high-pressure gas energy at 8 standard air pressures, which is sent to the gas-liquid booster device. The gas-liquid booster device boosts the gas pressure energy into high-pressure hydraulic energy, which is then delivered to the high-pressure storage tank by the high-pressure pump. The high-pressure storage tank maintains a constant hydraulic pressure of 20 standard air pressures, completing the efficient conversion of gas energy into hydraulic energy and realizing high-pressure power energy storage.

[0008] Using the high-pressure hydraulic energy of 20 standard hydraulic pressures in the high-pressure storage tank as the core driving power: on the one hand, the hydraulic drive mechanism directly drives the equipment steering components, completely eliminating the original vehicle's traditional electric steering gear and mechanical steering gear, simplifying the equipment structure and reducing power transmission loss; on the other hand, it directly replaces the traditional internal combustion engine as the main power source, providing kinetic energy for automobiles, mining machinery, and industrial equipment, completing the conversion of hydraulic energy into kinetic energy, and realizing four-energy coupling drive.

[0009] This power unit is equipped with a dedicated air pressure recovery device to form an energy closed-loop circulation system: it collects the residual gas generated by the equipment braking and the excess residual gas generated by the operation of the gas-liquid booster device, and returns both types of residual gas to the gas storage tank to participate in the gas production, boosting, and driving process again, realizing the recycling of gas energy, further reducing the energy consumption of dual power sources, and achieving four-energy closed-loop operation. Beneficial effects

[0010] 1. Reasonable patent integration and layout: This invention integrates multiple key technologies into a unified inventive concept, eliminating the need for separate applications, resulting in more comprehensive overall technical protection and avoiding the shortcomings of fragmented protection.

[0011] 2. Dual power source with strong adaptability: The electric air pump and phase change expansion are two independent gas production modes that can be freely selected and put into operation. It can be used for small-scale operation with a single energy source or combined to form a dual energy configuration to adapt to high-power conditions. It can be flexibly switched between single fuel mode and phase change fuelless mode as needed, making it suitable for a variety of scenarios.

[0012] 3. Four-energy closed-loop high efficiency and energy saving: Electric energy, gas energy, kinetic energy and hydraulic energy are cyclically converted, and residual gas is recovered and reused throughout the process, which greatly improves the energy utilization rate and the energy consumption is far lower than that of traditional power equipment, resulting in significant energy saving and consumption reduction effects.

[0013] 4. Simplified structure and convenient maintenance: The traditional steering gear is eliminated and a hydraulic direct drive structure is adopted, which reduces redundant mechanical parts, lowers the equipment failure rate and maintenance costs, and makes the structure more compact and adaptable.

[0014] 5. Strong versatility across multiple scenarios: It can directly replace traditional internal combustion engines and is applicable to multiple fields such as automobiles, large mining machinery, and power equipment in industrial plants. It has a wide range of applications and broad market prospects. Attached Figure Description

[0015] Figure 1 This is a block diagram illustrating the overall system structure of the present invention.

[0016] Figure 1 It includes an electric air pump, a phase change expansion gas generation mechanism, an air storage tank, a gas-liquid booster device, a high-pressure pump, a high-pressure storage tank, a hydraulic drive mechanism, and a gas pressure recovery device.

[0017] The workflow is as follows: the electric air pump and the phase change expansion gas generation mechanism generate high-pressure gas, which flows into the air storage tank. The high-pressure gas output from the air storage tank is transported to the high-pressure storage box via the gas-liquid booster device and the high-pressure pump. Then, the high-pressure storage box outputs power to the hydraulic drive mechanism. The air pressure recovery device collects the excess gas and brake gas from the system and returns them to the air storage tank, forming a four-energy closed-loop cycle working mode. Detailed Implementation

[0018] During installation, the electric air pump and phase change expansion gas generation mechanism are sealed and connected to the air storage tank through pressure-resistant pipelines, and the working pressure of the air storage tank is set to 8 standard air pressures; the gas-liquid booster device is connected to the air storage tank and the high-pressure storage box, and the hydraulic pressure of the high-pressure storage box is set to 20 standard air pressures; the air pressure recovery device is connected to the braking system, the gas-liquid booster device and the air storage tank respectively.

[0019] During operation, either the electric air pump or the phase change expansion mechanism can operate independently, depending on the usage requirements. It can be used for small-scale operation with a single fuel source, or for independent operation without fuel using phase change technology, depending on the working conditions. The electric air pump or the phase change expansion mechanism can be started independently to produce gas, or both power sources can be started simultaneously for combined gas supply. High-pressure gas energy is converted into high-pressure hydraulic energy through gas-liquid conversion, driving the equipment's operation and steering. During operation, the gas pressure recovery device automatically recovers residual gas and returns it to the gas storage tank, achieving a four-energy closed-loop cycle drive. No additional energy replenishment is required throughout the process, resulting in significant energy savings.
