Miniature gas turbine housing

Technical Field

This equipment is applied to miniature gas turbine field, especially relates to a miniature combustion engine housing.

Background

The large-scale gas turbine has a long industrial history, and the technology of matched auxiliary equipment is relatively mature; however, with the continuous development of the science and technology of society, the micro combustion engine is produced at the same time, and the main driving characteristic of the micro combustion engine is small, so that not only is the combustion engine small, but also auxiliary equipment of the combustion engine is small. A complete set of auxiliary equipment of the combustion engine needs to comprise: compared with a large-scale combustion engine, the micro combustion engine has the advantages that the requirement on shock absorption is improved, and the functional requirement is more.

The existing miniature gas turbine housing in the current market only has primary basic functions of sound insulation, rain protection, sun protection and the like, and cannot simultaneously meet the effects of small size, high sound insulation, shock absorption and the like. Because of limited space, how to meet the requirements of high sound insulation quantity and the air intake and ventilation functions of a combustion engine, and simultaneously have the damping function, and more importantly, the functions are integrated in a casing which is as small as possible, which is the key and difficult point of the technology.

Disclosure of Invention

The utility model aims to provide a miniature combustion engine housing which has the ultra-silent sound insulation and noise reduction functions.

The technical scheme of the utility model is as follows: the utility model provides a miniature combustion engine housing, includes housing body and chassis, is equipped with air inlet system, exhaust system and air intake system at the inside top of housing body, and this housing is whole to be rectangular bodily form, characterized by: the side wall of the housing is provided with a soundproof door, and a double-layer sealing rubber strip structure is arranged at the door seam position of the soundproof door.

The door gap structure of the soundproof door is designed to be Z-shaped.

And a shock absorber is arranged at the lower part of the chassis.

An electric control chamber is arranged in the housing body.

The side wall of the electric control chamber is composed of the sound insulation door, and a display screen is arranged on the sound insulation door.

The special double-layer sealing rubber strip structure is adopted at the crack position of the soundproof door, the crack structure is designed to be Z-shaped, noise does not pass through the crack directly but needs to be transmitted through a plurality of bends, leakage of the noise at the crack position can be effectively reduced, and the sound insulation and noise reduction effects of the gas turbine housing are greatly improved.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings and examples.

The integrated ultra-silent vibration reduction micro gas turbine housing mainly comprises a shock absorber 1, a chassis 2, a soundproof door 3, an air inlet system 4, an air exhaust system 5, an air inlet system 6, an electric control chamber 7 and a housing body 8.

The housing body 8 mainly realizes the functions of sound insulation and noise reduction.

The basic functions of the chassis 2 and the shock absorber 1 are to support the micro gas turbine and have a shock absorption function at the same time.

The soundproof door 3 has a soundproof function, and realizes the function that personnel can enter the housing to overhaul and maintain.

The air inlet system 4 and the air exhaust system 5 realize the function of maintaining the temperature in the housing to be in a proper range, and protect the combustion engine to effectively run for a long time.

The air inlet system 6 has a filtering function, and the cleanliness of air entering the internal part of the combustion engine is guaranteed.

The electric control chamber 7 is used for placing electric equipment of the gas turbine and controlling the gas turbine, the electric control chamber of the gas turbine is integrated in the housing, and meanwhile, the sound insulation effect is good. The lateral wall of automatically controlled room comprises the sound proof door, has set up outside display screen on the sound proof door of automatically controlled room, and operating personnel stands outside the housing and can operate, also very big saving the space simultaneously.

The key improvement points of the utility model are as follows:

1) according to the utility model, the special double-layer

sealing rubber strips

31 and 32 are adopted at the door gap position of the soundproof door, the door gap structure is designed into a Z shape, and the noise is not a straight passing gap part but needs to be transmitted through a plurality of bends, so that the leakage of the noise at the door gap position can be effectively reduced, and the soundproof and noise reduction effects of the enclosure of the gas turbine are greatly improved; simultaneously, the important auxiliary system of three big combustion engines of air inlet system, exhaust system and air intake system all sets up at the top of the inside of housing, through effectively dividing into a plurality of regions with the headspace, every region is relatively independent, realizes the function of ventilating and admitting air, sets up the silencer in each system simultaneously, guarantees the holistic sound insulation of housing and falls the function of making an uproar. The average noise at 1 meter of the box body is less than or equal to 65 +/-2 dB (A), and the noise requirement of the traditional combustion engine auxiliary equipment is less than or equal to 85dB, so that the overall sound insulation and noise reduction effect is improved, and the ultra-silent sound insulation and noise reduction effect is realized; the double-layer adhesive tape structure is shown in figure 4.

2) Although the size of the auxiliary equipment of the micro gas turbine is smaller, the air inlet system and the air exhaust system are integrated in the housing, and the air inlet system, the air inlet system and the air exhaust system are integrated at the top of the housing, so that the space is greatly saved, and the occupied space of the equipment is reduced; good ventilation can ensure that the temperature inside the housing is in a proper range, the temperature rise inside the box body is less than or equal to 8 ℃, the running environment of the combustion engine can be improved, the service life of the combustion engine is prolonged, and the point of temperature control cannot be abandoned due to small size.

3) The bottom of the device is provided with a shock absorber, so that the shock absorption function of the micro gas turbine during operation is realized;

4) the electric control room of the gas turbine is arranged in the housing through effective planning and division of space, the display screen mounting hole is formed in the soundproof door of the electric control room, the electric control room of the gas turbine does not need to be additionally arranged, space is saved, an operator can operate and observe an electric control system of the gas turbine on the premise that the operator does not need to enter the housing, and physical and mental health of the operator is guaranteed to a certain extent.
