Technical Field
[0001] This invention relates to the field of gas turbine power vehicle technology, specifically to a 3000kW low-noise, high-density gas turbine power vehicle. Background Technology
[0002] In the field of gas turbine power vehicles, gas turbine power vehicles, as a type of mobile emergency power supply equipment, are widely used in high-density crowd scenarios such as cultural and sports performances, exhibitions, and transportation hubs. These scenarios are characterized by dense crowds, high power loads, and limited space. Traditional diesel generator power vehicles have low power generation density, large space occupation, and high noise levels.
[0003] The traditional solution involves using a larger space and setting up sound barriers around the power vehicle, but the cost of space and sound barriers is too high, wasting manpower and resources. In first-tier cities, there are too many high-density locations such as events and transportation hubs, making the traditional approach even more wasteful. As emergency equipment for high-density crowds or large events, the spatial and noise impacts cannot be ignored. Therefore, there is a need for a gas turbine power vehicle that simultaneously meets the requirements of low noise and high density to solve these problems. Summary of the Invention
[0004] The purpose of this invention is to solve the problems of low power generation density, large space occupation, and high noise of traditional diesel generator sets in existing power vehicles, as well as the high cost of space and sound barriers around the power vehicle, which wastes manpower and resources. Therefore, this invention provides a 3000kW low-noise, high-density gas turbine power vehicle.
[0005] The technical solution adopted by the present invention to solve the above problems is as follows: a 3000kW low-noise high-density gas turbine power vehicle, comprising a vehicle chassis with an engine and a power unit, a soundproof enclosure mounted on the vehicle chassis, a gas turbine generator set and a shock-absorbing frame installed inside the soundproof enclosure, the gas turbine generator set being located on the upper part of the shock-absorbing frame; the gas turbine generator set being connected to an exhaust system and an intake system, the exhaust system being located at the front of the soundproof enclosure and the intake system being located in the middle of the soundproof enclosure; an air intake system being located at the rear of the soundproof enclosure and an exhaust system being located in the middle of the soundproof enclosure; the exhaust system, the intake system, the air intake system and the exhaust system are all equipped with silencers.
[0006] Furthermore, the shock-absorbing base frame is fixed at the middle position of the bottom of the soundproof enclosure; the rear of the soundproof enclosure is also equipped with an electrical control cabinet and a starting system.
[0007] Furthermore, the soundproof enclosure has a sandwich structure in its walls; the soundproof enclosure has doors on both sides, an air inlet louver at the rear, an exhaust louver in the middle, and an exhaust door at the top.
[0008] Furthermore, the sandwich structure is composed of steel plates, sound-absorbing perforated plates, and ultra-fine glass wool, with two layers of sound-absorbing perforated plates placed between the two layers of steel plates and ultra-fine glass wool placed between the two layers of sound-absorbing perforated plates.
[0009] Furthermore, both the air inlet louvers and the air outlet louvers are made of aluminum alloy, and the louver blades are streamlined.
[0010] Furthermore, the gas turbine generator set includes a gas turbine and a generator; the gas turbine and the generator are connected by a coupling, and the gas turbine is connected to the main gas turbine support, the auxiliary gas turbine support, and the shock-absorbing base frame.
[0011] Furthermore, the exhaust system includes an exhaust transition section and an exhaust muffler, which are separated by a compartment; the exhaust transition section is connected to the exhaust port of the gas turbine; the exhaust muffler is equipped with a sound-absorbing baffle, which is a sandwich structure of two layers of sound-absorbing perforated plates with ultra-fine glass wool in between.
[0012] Furthermore, the intake system includes an intake connection section, an intake elbow, and an intake muffler; the intake connection section is connected to the intake muffler via the intake elbow, and the intake connection section is connected to the intake interface of the gas turbine; the intake muffler is internally equipped with a sound-absorbing baffle, which is a sandwich structure of two layers of sound-absorbing perforated plates with ultra-fine glass wool in between.
[0013] Furthermore, the air intake system includes an air intake filter and an air intake silencer. The air intake silencer is made of perforated ultra-fine glass wool substrate. Outside air passes through the air intake louvers, is filtered by the air intake filter to remove dust and impurities, and then enters the soundproof enclosure after noise reduction by the air intake silencer.
[0014] Furthermore, the exhaust system includes an exhaust fan, an exhaust elbow, and an exhaust silencer; the exhaust elbow and the exhaust silencer are connected, and the exhaust silencer is equipped with a sound-absorbing baffle inside, which is a sandwich structure of two layers of sound-absorbing perforated plates with ultra-fine glass wool in between; the hot air inside the soundproof box is driven by the exhaust fan, enters the exhaust silencer through the exhaust elbow to reduce noise, and is finally discharged from the exhaust louvers on both sides of the soundproof box.
[0015] The present invention has the following beneficial technical effects:
[0016] The ventilation system of the gas turbine generator set of this invention adopts an air intake louver at the rear of the soundproof enclosure, through which air enters the enclosure and passes through an intake filter and an intake silencer, supplying the gas turbine generator set with intake and cooling air. Exhaust air, driven by the exhaust fan of the exhaust system, passes through an exhaust silencer and is discharged through exhaust louvers on both sides of the soundproof enclosure. During the operation of the gas turbine generator set, the soundproof enclosure and silencer effectively reduce the noise radiated outwards by the gas turbine generator set, thereby ensuring the normal work and daily life of the people.
[0017] The flue gas from the combustion of the gas turbine generator set in this invention passes through the exhaust transition section of the exhaust system, then through the exhaust silencer, and is discharged through the exhaust valve at the top front of the soundproof enclosure, posing no hazard to surrounding personnel. This invention employs an integrated enclosure design to ensure structural stability and operational safety.
[0018] This invention achieves a noise reduction of up to 45dB, with a full-load output noise of only 79dB at a distance of 1 meter from the enclosure and ventilation openings. In contrast, other power supply vehicles on the market, such as 1000kW diesel engine and gas turbine power supply vehicles, have a full-load output noise of 85dB at a distance of 1 meter from the enclosure. Compared to other products, this invention represents a noise level equivalent to normal conversation in an office, while other products are comparable to the noise level of a busy street. This invention is particularly suitable for scenarios with noise restrictions, such as emergency power supply, municipal services, communications, and large-scale events. From an occupational health perspective, 85dB is the threshold for hearing damage after 8 hours of exposure. The power supply vehicle industry standard is designed only according to this threshold; the noise level of this invention is far below this threshold. Simultaneously, it exhibits low flow resistance loss. The design of the air intake silencer in the air intake system prioritizes minimizing flow resistance loss within limited space.
[0019] The air inlet and exhaust louvers of this invention are made of finished rare earth aluminum alloy louvers, which can be opened to 90 degrees in both electric and manual modes. The blades are streamlined to ensure minimal air resistance.
[0020] This invention is used for emergency power supply. When there is an urgent need for power supply or backup in situations such as large-scale performances, forums, summits, disaster relief and resettlement, the power supply vehicle will rush to provide power supply and ensure power supply. Such places are often located in noise-sensitive areas.
[0021] The power supply vehicle chassis of this invention occupies an area of 29.5㎡ and has an output power of 3000kW. Currently, other power supply vehicles on the market, with the same chassis size, have output power of only 1000kW for diesel engine power supply vehicles and only 1600kW for gas turbine power supply vehicles. Under the same footprint, the power density of this invention is more than 3 times that of diesel engine power supply vehicles and more than 1.8 times that of gas turbine power supply vehicles, far exceeding the current industry level.

[0071] The electrical control cabinet 10 is located on the right side of the soundproof enclosure 2. As the control core of the entire power vehicle, the electrical control cabinet 10 integrates functions such as power control, unit start-up and shutdown, parameter monitoring, and fault alarm. The starting system 11 is located on the left side of the soundproof enclosure 2 to provide starting power for the gas turbine generator set 3, ensuring that the power vehicle can be quickly put into use in an emergency.
[0072] In this embodiment, the soundproof enclosure 2 is an integral box-type structure, which is the core carrier for achieving low noise in the power supply vehicle. Its overall size is adapted to the four-axle automobile chassis 1 (length 11800mm, width 2500mm, height 3990mm). The soundproof enclosure 2 is 9600mm long and includes an enclosure door 201, air inlet louvers 202, air outlet louvers 203, exhaust valve 204, and skirt 205. The enclosure door 201 adopts a sealed design and, together with a soundproof sealing strip, prevents internal noise from leaking out of the enclosure 2. The skirt 205 covers the exposed parts of the automobile chassis 1, taking into account both protection and aesthetics. The main body of the soundproof enclosure 2 is a sandwich structure, consisting of an outer steel plate, a middle ultra-fine glass wool sound-absorbing layer, and an inner sound-absorbing perforated plate. The steel plate ensures the structural strength of the enclosure, while the sound-absorbing perforated plate allows noise waves inside the enclosure to enter the ultra-fine glass wool layer. Through the adhesion and friction of the sound-absorbing material, efficient sound insulation is achieved. The integrated enclosure design also improves the equipment's shock resistance and protection, making it suitable for outdoor mobile use and complex road conditions.
[0073] Furthermore, the air inlet louvers 202 and exhaust louvers 203 on the soundproof enclosure 2 are both made of finished aluminum alloy louvers. This material is lightweight, high-strength, and corrosion-resistant, making it suitable for the outdoor environment requirements of the power supply vehicle. The louvers are equipped with both electric and manual opening methods, and can be fully opened to 90 degrees. The blades adopt a streamlined design to minimize airflow resistance loss during air passage, ensuring the air intake and exhaust efficiency of the ventilation system. At the same time, the aluminum alloy louvers have good sealing performance, and can effectively prevent external impurities from entering the interior of the soundproof enclosure 2 when closed.
[0074] In this embodiment, the various noise reduction components of the power vehicle work together to achieve an overall noise reduction of 45dB. While achieving efficient noise reduction, all noise reduction devices follow the design principle of "minimum flow resistance loss". In particular, the air intake silencer 702 of the air intake system 7 makes full use of the limited space at the rear of the soundproof box 2 for structural optimization, which not only ensures the noise reduction effect, but also avoids the impact of excessive flow resistance on the air intake and cooling efficiency of the gas turbine 301, ensuring that the unit is always in the best working state and stably outputs 3000kW power.
[0075] In addition, this power supply vehicle is based on a four-axle automobile chassis design, with the chassis occupying only 29.5㎡. Combined with an output power of 3000kW, it achieves an ultra-high power density, far exceeding the level of existing diesel generator power supply vehicles and traditional gas turbine power supply vehicles in the industry, solving the pain points of traditional power supply equipment such as "low power generation density and large space occupation".

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
