Description

Technical Field

[0001] The utility model belongs to the technical field of diesel generators, and particularly relates to a cabin structure for a diesel generator and a special vehicle. Background Technique

[0002] The diesel generator is an important part of the temperature control system on a special vehicle. It is installed in the diesel generator cabin of the special vehicle, and the diesel generator cabin is fixed on the chassis of the special vehicle. The main function of this temperature control system is to automatically control the temperature of the thermal insulation cabin. Specifically, when the temperature of the thermal insulation cabin on the special vehicle is higher than +34°C, the diesel generator starts to work, supplies power to the air conditioner in the thermal insulation cabin, and the air conditioner cools the thermal insulation cabin after working; when the temperature of the thermal insulation cabin drops below +30°C, the diesel generator set stops working.

[0003] However, when the diesel generator is working, a large amount of heat is generated by the hot air discharged from its air outlet and the exhaust gas discharged from the exhaust pipe. The space inside the diesel generator cabin is relatively narrow. If the heat accumulated inside the cabin cannot be dissipated in time, the temperature inside the cabin will continue to rise, even exceeding the normal working temperature range of the diesel generator, which is extremely likely to cause problems such as abnormal shutdown of the diesel generator due to high temperature and coking and deformation of its own components, thus affecting the normal operation of the diesel generator. Content of the Utility Model

[0004] Aiming at the above defects or improvement requirements of the prior art, the utility model provides a cabin structure for a diesel generator and a special vehicle, aiming to avoid the problem of continuous temperature rise inside the cabin, and thus avoid the problem that the temperature inside the cabin exceeds the normal working temperature range of the diesel generator, and ensure the normal operation of the diesel generator.

[0005] To achieve the above object, in the first aspect, the utility model provides a cabin structure for a diesel generator, and the cabin structure includes a diesel generator cabin and a heat dissipation assembly;

[0006] A cabin door for sealing the inner cavity of the diesel generator cabin is movably arranged on the diesel generator cabin. The diesel generator cabin is provided with an air inlet, an air outlet and an exhaust outlet, and the air inlet and the air outlet are arranged oppositely;

The axial flow fan is inserted into the air outlet, and one end of the heat insulation sleeve is used to sleeve outside the exhaust pipe of the diesel generator, and the other end of the heat insulation sleeve is communicated with the exhaust outlet.

[0008] Optionally, the heat dissipation component further includes a deflector, which is used to be installed on the diesel generator. The deflector is arranged obliquely and is located below the air inlet and the air outlet to deflect the gas from the air outlet of the diesel generator to between the air inlet and the air outlet.

[0009] Optionally, the diesel generator cabin is of a trapezoidal structure.

[0010] Optionally, a louver is inserted in the air inlet.

[0011] Optionally, the louver is located on the cabin door.

[0012] Optionally, the heat dissipation component further includes an air duct. One end of the air duct is used to communicate with the air inlet of the diesel generator, and the other end of the air duct extends to the air inlet.

[0013] Optionally, the cabin structure further includes a mounting bracket, which is slidably arranged in the diesel generator cabin and is used to mount the diesel generator.

[0014] Optionally, the mounting bracket has a plurality of mounting holes arranged at intervals, and connecting bolts are inserted into the mounting holes to connect the diesel generator.

[0015] Optionally, the heat insulation sleeve is made of alumina.

[0019] For a cabin structure for a diesel generator provided by an embodiment of the present invention, the diesel generator is placed in the diesel generator cabin, and the diesel generator cabin can be fixed on a special vehicle.

[0020] When the diesel generator is working, outside air can enter the diesel generator compartment through the air inlet, and is inhaled into the diesel generator through the air intake port and then mixed with diesel for combustion. The high-temperature exhaust gas generated after the diesel combustion is discharged through the exhaust pipe of the diesel generator, and the temperature of this exhaust pipe is high. The heat insulation sleeve can, on the one hand, timely guide the exhaust gas to the air outlet and then discharge it outside the diesel generator compartment, and on the other hand, prevent heat transfer to the inside of the diesel generator compartment through its heat insulation property, avoiding the problem of continuous increase in the temperature inside the compartment. In addition, during the operation of the diesel generator, hot air will be correspondingly generated and discharged through the air outlet of the diesel generator, and this hot air will be forced to be exhausted outside the diesel generator compartment by the axial flow fan, further avoiding the problem of continuous increase in the temperature inside the compartment, and thus avoiding the problem that the temperature inside the compartment exceeds the normal working temperature range of the diesel generator, ensuring the normal operation of the diesel generator.

[0021] That is to say, a compartment structure for a diesel generator provided by an embodiment of the present invention can avoid the problem of continuous increase in the temperature inside the compartment, and thus avoid the problem that the temperature inside the compartment exceeds the normal working temperature range of the diesel generator, ensuring the normal operation of the diesel generator.

[0031] Embodiment:

[0032] Figure 1 is the front view of a cabin structure for a diesel generator provided by an embodiment of the present utility model, Figure 2 is the cross-sectional view of a cabin structure for a diesel generator provided by an embodiment of the present utility model, combined with Figure 1 andFigure 2 As shown, the cabin structure includes a diesel generator cabin 1 and a heat dissipation component 2.

[0033] A cabin door 11 for sealing the inner cavity of the diesel generator cabin 1 is movably arranged on the diesel generator cabin 1. The diesel generator cabin 1 is provided with an air inlet 12, an air outlet 13 and an exhaust outlet 14, and the air inlet 12 and the air outlet 13 are arranged opposite to each other.

[0034] The heat dissipation component 2 includes an axial flow fan 21 and a heat insulation sleeve 22. The axial flow fan 21 is inserted into the air outlet 13. One end of the heat insulation sleeve 22 is used to sleeve the exhaust pipe 101 of the diesel generator 100, and the other end of the heat insulation sleeve 22 is communicated with the exhaust outlet 14.

[0035] For a cabin structure for a diesel generator provided by an embodiment of the present invention, the diesel generator 100 is placed in the diesel generator cabin 1, and the diesel generator cabin 1 can be fixed on a special vehicle.

[0036] When the diesel generator 100 works, outside air can enter the diesel generator cabin 1 through the air inlet 12 and is sucked into the diesel generator 100 through the air inlet 103 and then mixed with diesel for combustion. The high-temperature waste gas generated after the diesel combustion is discharged through the exhaust pipe 101 of the diesel generator 100, and the temperature of this exhaust pipe 101 is high. The heat insulation sleeve 22 can, on the one hand, timely introduce the waste gas into the exhaust outlet 14 and then discharge it outside the diesel generator cabin 1, and on the other hand, prevent heat from being transferred to the inside of the diesel generator cabin 1 through its heat insulation property, avoiding the problem of continuous increase of the temperature in the cabin. In addition, hot air will be generated correspondingly during the operation of the diesel generator 100 and discharged through the air outlet 102 of the diesel generator 100, and these hot air will be forced to be pumped out of the diesel generator cabin 1 by the axial flow fan 21, thereby further avoiding the problem of continuous increase of the temperature in the cabin, and also avoiding the problem that the temperature in the cabin exceeds the normal working temperature range of the diesel generator 100, ensuring the normal operation of the diesel generator 100.

[0037] That is to say, a cabin structure for a diesel generator provided by an embodiment of the present invention can avoid the problem of continuous increase of the temperature in the cabin, and also avoid the problem that the temperature in the cabin exceeds the normal working temperature range of the diesel generator 100, ensuring the normal operation of the diesel generator 100.

[0038] It should be noted that the heat insulation sleeve 22 can also cover the silencer of the diesel generator 100. In addition, when installing the diesel generator 100 in the diesel generator cabin 1, the air inlet 103 of the diesel generator 100 is close to the air inlet 12, and the air outlet 102 of the diesel generator 100 is close to the air outlet 13, which is convenient for rapid air intake and air outlet.

[0039] Exemplarily, the exhaust port 14 is located at the bottom surface of the diesel generator housing 1, and the air inlet 12 and the air outlet 13 are respectively located at the front and back of the diesel generator housing 1.

[0040] Exemplarily, the heat insulation sleeve 22 is made of alumina and has a good heat insulation effect.

[0041] In an implementation manner of the present utility model, the heat dissipation assembly 2 further includes a deflector 23. The deflector 23 is used to be installed on the diesel generator 100. The deflector 23 is arranged obliquely and is located below the air inlet 12 and the air outlet 13 to deflect the gas from the air outlet 102 (horizontally arranged) of the diesel generator 100 to between the air inlet 12 and the air outlet 13.

[0042] In the above implementation manner, the deflector 23 can direct the hot air discharged from the air outlet 102 of the diesel generator 100 upward, which can ensure the smooth air path between the front and rear plates of the diesel generator housing 1, shorten the travel of the hot air flow, and ensure the efficient outflow of the hot air from the diesel generator housing 1.

[0043] Exemplarily, the deflector 23 can be a U-shaped structure, and it forms an upward channel with the outer shell of the diesel generator housing 1 to deflect the gas from the air outlet 102 of the diesel generator 100 vertically upward.

[0044] In this embodiment, the diesel generator housing 1 is a trapezoidal structure. That is, at least one side ( Figure 1 the right side) of the diesel generator housing 1 is arranged obliquely, which can avoid contact with the wheels of the special vehicle and increase the installation range of the diesel generator housing 1 on the special vehicle.

[0045] Refer to again Figure 1 , a louver 121 is inserted in the air inlet 12, so as to prevent large-size impurities from being carried when the outside air enters the air inlet 12.

[0046] Exemplarily, the louver 121 is located on the hatch 11, which is convenient for processing and installation.

[0047] In this embodiment, the heat dissipation assembly 2 further includes an air duct 24. One end of the air duct 24 is used to communicate with the air inlet 103 of the diesel generator 100, and the other end of the air duct 24 extends to the air inlet 12. The air duct 24 can directly introduce the outside air entering the air inlet 12 into the air inlet 103 of the diesel generator 100, and the air intake efficiency is higher.

[0048] Exemplarily, the air duct 24 can be a PVC pipe.

[0049] In addition, the cabin structure further includes a mounting bracket 3 which is slidably arranged in the diesel generator cabin 1 and is used for mounting the diesel generator 100. The mounting bracket 3 can support and slide the diesel generator cabin 1, thus facilitating the transportation and installation of the diesel generator cabin 1.

[0050] Exemplarily, the mounting bracket 3 has a plurality of mounting holes arranged at intervals, and connecting bolts are inserted into each mounting hole to connect the diesel generator 100, so as to realize the mounting of the diesel generator 100 on the mounting bracket 3 through the connecting bolts.

[0051] It should be noted that the cabin structure has been subjected to a normal temperature static verification test and a 50°C high temperature verification test. The diesel generator 100 runs continuously for two hours respectively under the two conditions. During the test, the diesel generator 100 runs normally. The cabin basically reaches a thermal equilibrium state about half an hour after the diesel generator 100 starts running, and the air temperature in the diesel generator cabin 1 does not exceed the normal working temperature of the diesel generator 100. After the test, check the appearance and panel components of the diesel generator 100 group, and there is no high temperature deformation or damage.

[0052] The embodiment of the present invention also provides a special vehicle, which includes a cabin structure for a diesel generator as described above.

[0053] Those skilled in the art can easily understand that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
