Description

Technical Field

[0001] The utility model relates to the technical field of power generation and air compression equipment, in particular to a silent dual-purpose power generation and air compression equipment. Background Art

[0002] In the existing technical field, generator sets and air compressors, as key equipment for energy conversion and gas compression, are widely used in various industrial, commercial and life scenarios. Traditionally, these two types of equipment mostly adopt a split design, that is, the generator set usually uses a diesel engine or other power machinery to drive the generator to generate electricity, while the air compressor converts mechanical energy into gas pressure energy through another mechanical system (such as an independent diesel engine or electric drive); some also adopt an integrated but independently driven design, that is, the diesel engine drives the motor to generate electricity, and then uses the generated electricity to drive the compression host to produce compressed gas. Although these two design methods have met the supply needs of electricity and compressed gas to a certain extent, they also have many shortcomings.

[0003] First, the independently driven, integrated design results in bulky and complex equipment, increasing manufacturing costs and process complexity while also occupying significant space. While the split design is smaller, when both a generator set and an air compressor are required, users must purchase and install two separate units, requiring significant space. This not only increases initial investment but also creates inconvenience during subsequent operations and maintenance.

[0004] Secondly, traditional diesel engines and other power machinery are often designed to operate in open-frame configurations, generating significant noise pollution that negatively impacts both operators and the surrounding environment. Long-term exposure to high noise levels not only affects workers' physical and mental health but can also lead to safety incidents.

[0005] Furthermore, from an energy utilization perspective, traditional designs, where the generator set and air compressor are driven by separate power sources, result in energy waste and reduced efficiency. Especially in applications where both power and air supply are required, operating both devices simultaneously not only increases energy consumption but can also reduce overall efficiency.

[0006] In view of the above problems, the market is in urgent need of a device that can integrate power generation and gas compression functions, has a compact structure, high efficiency and low noise. Utility Model Content

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0026] Example 1:

[0027] See attached Figures 1 to 3. The present embodiment provides a silent dual-purpose power generation and air compression device, comprising a box body with a cavity formed therein; a motor 3, a compression host 2 and a diesel engine 1 are arranged in the box body, and the front and rear ends of the diesel engine 1 are respectively connected to the motor 3 and the compression host 2, and the diesel engine 1 is used to provide power output for the motor 3 and the compression host 2. It can be understood that the present embodiment does not limit the specific structure of the motor 3, the compression host 2 and the diesel engine 1. The motor 3, the compression host 2 and the diesel engine 1 can adopt existing technologies. For example, the compression host 2 can be a screw air compressor. The utility model drives the motor 3 and the compression host 2 to work at the same time through the diesel engine 1, which not only realizes the synchronous supply of electricity and compressed gas, but also greatly improves the energy utilization efficiency and reduces the production cost and operation and maintenance difficulty.

[0028] Example 2:

[0029] See attached Figures 1 to 3 Based on the first embodiment, the silent dual-purpose power generation and air compression device further includes a radiator 4. The motor 3 and the compressor main unit 2 are respectively connected to the radiator 4. The radiator 4 can be located on the side of the diesel engine 1 near the motor 3. The motor 3 can provide power to the radiator 4, and the radiator 4 can be used to dissipate heat for the compressor main unit 2. The radiator 4 can also be implemented using existing technology.

[0030] In this embodiment, the silent dual-purpose power generation and air compression device also includes a control system, to which the motor 3, the compressor main unit 2, and the diesel engine 1 are respectively connected. The operation of the motor 3 and the compressor main unit 2 can be controlled by the control system separately without interfering with each other.

[0031] Specifically, the connection between the diesel engine 1 and the compression host 2 is as follows:

[0032] like Figure 2 As shown, diesel engine 1 is equipped with an intake pipe for communicating with air. A crankshaft pulley 9 is provided at the front end of diesel engine 1, and a flywheel is provided at the rear end of diesel engine 1. The flywheel at the rear end of diesel engine 1 is connected to the main shaft of compressor main unit 2 via coupling 1 and a shaft sleeve. A central bracket 7 is then used to secure diesel engine 1 and compressor main unit 2, both of which can be secured by bolts. The outlet of compressor main unit 2 is connected to an oil separator barrel 5 via an oil pipe, which can be bolted. The oil separator barrel 5 is connected to radiator 4 via a temperature control valve 12, which controls the operation of radiator 4. The oil-gas mixture compressed gas generated by compression in compressor main unit 2 then enters oil separator barrel 5, where the oil and gas are separated, producing compressed gas, which is then discharged through exhaust valve 13. Air filter 14 can be provided on the intake pipe of diesel engine 1, and air filter 2 can be provided on the intake port of compressor main unit 2. Air filter 14 and air filter 2 can effectively filter dust and impurities from the air, thereby increasing the purity of the air entering the combustion chamber or working chamber.

[0033] Specifically, the connection between the diesel engine 1 and the motor 3 is as follows:

[0034] The crankshaft pulley 9 at the front end of the diesel engine 1 is connected to the main shaft of the motor 3 via a coupling 8, which can be secured with bolts. The power output of the motor 3 is connected to the radiator 4, providing power to the radiator 4. The entire process of generating electricity by the generator set is controlled by a circuit control system. A circuit control cabinet 6 can be installed within the box to house the circuit control system.

[0035] Example 3:

[0036] See attached Figures 1 to 3 In this embodiment, based on the second embodiment, the motor 3, the compressor main unit 2, and the diesel engine 1 are all fixed to the housing or to a carrier within the housing via shock-absorbing pads, which are fixedly connected to the housing. The provision of shock-absorbing pads can effectively buffer and reduce vibrations generated during equipment operation.

[0037] In this embodiment, the inner wall of the box is provided with a sound-absorbing material, which can be a sound-absorbing cotton. This material is attached to the inner wall of the box to provide sound insulation and reduce the noise generated by the operation of the diesel engine 1. The outer side of the box can also be provided with a separate removable door panel. Unlike traditional hinged door panels, three removable door panels can be provided on a single side, increasing the inspection space and facilitating maintenance. The door panel joints are separated by shock-absorbing rubber strips to reduce noise generated by door panel vibration.

[0038] The working principle of the silent dual-purpose power generation and air compression device provided by the utility model is:

[0039] First, diesel engine 1 drives the compressor main unit 2, which also drives motor 3. Within the screw compressor main unit, a pair of spiral rotors rotate continuously, drawing air in through intake valve 10. The screw continues to rotate, and as the two screw teeth squeeze each other, the air volume gradually decreases. The compressed air is then sent out of the compressor main unit 2 and into the oil separator 5, where it is separated into compressed gas. Simultaneously, diesel engine 1 drives motor 3, which converts mechanical energy into electrical energy through electromagnetic induction, providing power to radiator 4 and external devices. The generator set and compressor are controlled independently by control systems.
