Description

Technical Field

[0001] The utility model relates to the technical field of generators, and particularly to an internal combustion engine gas generating set. Background Technique

[0002] An internal combustion engine gas generating set is a device that uses an internal combustion engine to burn gaseous fuels (such as natural gas, biogas, liquefied petroleum gas, etc.) to drive a generator to generate electricity. The existing gas generating sets have poor versatility and cannot be applied to various different gas source pressures, so they cannot meet the needs of customers to the greatest extent. Moreover, the existing ordinary gas generating sets cannot well adapt to the ambient temperature, making them inconvenient to use. Therefore, the utility model designs an internal combustion engine gas generating set with high working efficiency and wide application range. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide an internal combustion engine gas generating set with reasonable structural design, strong versatility, applicable to various gas source pressures of high pressure, medium pressure and low pressure; wide applicable media, and adaptable to a variety of generators and engines, facilitating maintenance and repair, and being able to well adapt to the ambient temperature, being more convenient, reliable and practical in use.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: An internal combustion engine gas generating set includes a box body. The box body includes a heat dissipation compartment, a generator compartment and a control room compartment. The heat dissipation compartment and the control room compartment are respectively arranged on both sides of the generator compartment. The unit control cabinet is fixedly installed on the floor in the control room compartment through bolts. A gas engine, a unit base and a generator are arranged in the generator compartment. The generator is connected to the gas engine through bolts. The gas engine and the generator are fixedly installed on the unit base through bolts to form a single unit. The radiator water tank and the intermediate cooler are fixedly installed in the heat dissipation compartment through bolts. The first electronic axial flow fan and the second electronic axial flow fan are fixedly installed on the top of the box body through bolts. The second movable aluminum alloy louver and the third movable aluminum alloy louver are installed on the door panels at both ends of the box body. The first movable aluminum alloy louver is installed at the tail ends on both sides of the box body.

[0005] Preferably, the radiator water tank and the intermediate cooler are connected to the single unit through pipelines.

[0006] Preferably, a muffler is also installed on the top of the box body.

[0007] Preferably, the first movable aluminum alloy louver, the second movable aluminum alloy louver and the third movable aluminum alloy louver are all louvers with adjustable opening degrees.

[0008] Preferably, the unit control cabinet is connected to the single unit set (a single unit set is composed of multiple single units) through wire grooves, cable wires and intermediate connecting wires in the unit chassis.

[0009] The utility model has the following beneficial effects:

[0010] 1. The generator set of the utility model has strong versatility, is applicable to various gas source pressures of high pressure, medium pressure and low pressure; has a wide range of applicable media, and is adapted to a variety of generators and engines. Compared with ordinary gas generator sets, it can better meet the needs of users.

[0011] 2. It can better adapt to the ambient temperature. Compared with ordinary gas generator sets, the structure of the heat dissipation components is changed, and three adjustable aluminum alloy louvers are adopted. When the ambient temperature is low, the first and second aluminum alloy louvers are closed, and the third aluminum alloy louver is opened, and its opening degree is adjusted. Under the condition of meeting the normal operation of the unit, the ventilation air volume of the intercooler can be reduced, and then the cooling amplitude of the intercooler can be reduced, so that the high-temperature gas passing through the engine supercharger can be reduced to an appropriate temperature when passing through the intercooler, but a large amount of condensed water is not generated. This can reduce the failures of the engine caused by excessive condensed water and increase the service life of the engine; when the ambient temperature is high, the third aluminum alloy louver is closed, the first and second aluminum alloy louvers are opened, and their opening degrees are adjusted to increase the air intake volume and enhance the cooling effect.

[0012] 3. It is convenient for maintenance. The cooling components are located at both ends, and there is enough space for the maintenance of the intercooler and the radiator. Description of the Drawings

[0017] Refer to Figure 1-2, this specific embodiment adopts the following technical solution: An internal combustion engine gas generating set, including a box body, the box body includes a heat dissipation compartment 12, a generator compartment 13 and a control room compartment 14. The heat dissipation compartment 12 and the control room compartment 14 are respectively arranged on both sides of the generator compartment 13. On the floor in the control room compartment 14, a unit control cabinet 10 is fixed by bolts. In the generator compartment 13, a gas engine 7, a unit base 8 and a generator 9 are arranged. The generator 9 is connected to the gas engine 7 by bolts, and the gas engine 7 and the generator 9 are fixed on the unit base 8 by bolts to form a single unit. A radiator 3 and an intercooler 4 are fixed in the heat dissipation compartment 12 by bolts. A first electronic axial flow fan 11 and a second electronic axial flow fan 6 are fixed on the top of the box body by bolts. A second movable aluminum alloy shutter 2 and a third movable aluminum alloy shutter 1 are installed on the door panels at both ends of the box body. A first movable aluminum alloy shutter 5 is installed at the tail ends on both sides of the box body.

[0018] It should be noted that the radiator 3 and the intercooler 4 are connected to the single unit through pipelines.

[0019] It should be noted that a muffler is also installed on the top of the box body 3.

[0020] It should be noted that the first movable aluminum alloy shutter 5, the second movable aluminum alloy shutter 2 and the third movable aluminum alloy shutter 1 are all shutters with adjustable opening degrees.

[0021] In addition, the unit control cabinet 10 is connected to the single unit (a single unit is composed of multiple single units) through the wire grooves, cable wires and intermediate connecting wires in the unit chassis.

[0022] The control cabinet of this specific embodiment is fixed on the floor of the control room compartment by bolts. The unit chassis has wire grooves. The control cabinet is connected to the single unit through cable wires, intermediate connecting wires, etc. The engine and the generator are connected by bolts and fixed on the unit base by bolts to form a single unit. The single unit is fixed in each compartment by bolts. The intercooler and the radiator are fixed in the heat dissipation compartment by bolts and connected to the single unit through pipelines. The first and second electronic axial flow fans are fixed on the top of the box body by bolts. The second and third movable aluminum alloy shutters are installed on the door panels at both ends of the box body. The first movable aluminum alloy shutter is installed at the tail ends on both sides of the box body, and the muffler is installed on the top mounting seat of the unit.

[0023] The working principle of this specific embodiment:

[0024] 1. The entire generating set is divided into 3 external functional areas: the control room compartment, the generator compartment, and the heat dissipation compartment;

[0025] 2. The control cabinet is placed in the control cabinet compartment, and the operation of the entire generating set is controlled by the control cabinet;

[0026] 3. Each generator compartment is equipped with two single-unit generators, and there is an electronic axial flow fan above each single unit. During operation, the heat generated by the engine is discharged and fresh air from the outside is inhaled.

[0027] 4. Fresh air is inhaled through an air filter, pressurized by a supercharger, cooled down by an intercooler, mixed with gas in a mixer, and enters each cylinder of the engine through a throttle valve for combustion. The engine rotation drives the generator to generate electricity. The exhaust gas after combustion drives the supercharger to rotate and inhale air, and then is discharged through an exhaust pipe - exhaust extension pipe - muffler;

[0028] 5. When the engine is running, the internal pump makes the coolant flow between the engine and the water tank. The low-temperature coolant flows through the engine to dissipate heat from the engine and becomes high-temperature coolant. The high-temperature coolant flows through the radiator water tank, and the electronic axial flow fan blows air to dissipate heat from the water tank. The high-temperature coolant becomes low-temperature coolant and then flows back to the engine, repeating this process;

[0029] 6. When the high-temperature mixture passes through the intercooler, it dissipates heat and cools down to become a low-temperature mixture. When the ambient temperature is high, the third movable aluminum alloy louver will be completely closed, and the first and second movable aluminum alloy louvers will be opened, enabling the air from the electronic axial flow fan to maximize the heat dissipation of the intercooler and reduce the temperature of the mixture. When the ambient temperature is low, the third movable aluminum alloy louver will be opened, and the first and second movable aluminum alloy louvers will reduce the opening degree or even close, enabling the air from the electronic axial flow fan to slightly dissipate heat from the intercooler to avoid a large amount of condensate water generated after the rapid cooling of the high-temperature mixture.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
