Abstract
The utility model discloses a water resistance test noise-reducing storehouse of an internal combustion locomotive, which comprises a storehouse body, a track at the bottom part of the storehouse body and a smoke discharging tube located at the top part of the storehouse body; underground air inlets are arranged at both sides along the track, the top part of the storehouse body is provided with a venting and radiating passage; and a muffler is arranged on the venting and radiating passage. According to the water resistance test noise-reducing storehouse of the internal combustion locomotive, the reinforced radiation in the storehouse is changed to be natural venting and radiating method, the hot air flow in the storehouse body is discharged through the locomotive and the venting and radiating passage with the muffler so as to keep the uniform air flow field and avoid overheating; the energy consumption generated by the noise reducing measure is zero basically, so that the purpose of saving energy and reducing dissipation is achieved; due to the method of saving energy and reducing dissipation, the energy dissipation generated by a noise reducing facility is reduced largely, decreases the work load for repairing and maintaining the noise reducing facility is decreased, and the labor intensity of the working staff is alleviated. The noise reducing effect of the water resistance test noise-reducing storehouse of the internal combustion locomotive can satisfy the requirement of environment noise standard.
Description
Technical field
The utility model relates to beeliner waterr rheostat test storehouse, refers to a kind of diesel locomotive waterr rheostat test noise reduction storehouse particularly.
Background technology
Satisfying diesel locomotive waterr rheostat test requirement is noise reduction storehouse key for design.The noise that locomotive produces in the time of should reducing waterr rheostat test ensures that again test condition is basic identical with open-air test at present in the storehouse, the real-time working condition of simulation locomotive operation to the influence of surrounding enviroment.
At present, traditional locomotive test has following two kinds:
The one, open-air test, but the noise that locomotive produces during waterr rheostat test is big to the influence of surrounding enviroment, and the employee of near resident and locomotive depot self has strong complaints;
The 2nd, the totally enclosed type private library is set, adopt the mechanical ventilation mode usually, but mechanism is complicated, operate loaded down with trivial detailsly, use cost is higher during test; The noise of blower fan self is difficult to eliminate simultaneously, and noise reduction is undesirable.
Summary of the invention
The purpose of the utility model will overcome the existing in prior technology deficiency exactly, provides a kind of simple in structure, and cost is low, the diesel locomotive waterr rheostat test noise reduction storehouse of natural ventilation, in the time of can effectively solving the test of present diesel locomotive to the problem of the influence of surrounding enviroment.
For realizing above-mentioned purpose; The diesel locomotive waterr rheostat test noise reduction storehouse that the utility model designed; It comprises storehouse body, the track of storehouse body bottom and the smoke exhaust pipe at body top, storehouse; Along both side be provided with underground air intake duct at track, body top, said storehouse is provided with the ventilation and heat passage, and said ventilation and heat passage is provided with sound suppressor.
In the such scheme, the end of said underground air intake duct is provided with sump.Like this, the water in the body of storehouse can flow out from the sump of underground air intake duct end.
Preferably, said underground air intake duct above be provided with the cover plate of iron railings structure.
Like this, fresh air is arranged not only in the body of storehouse, and do not influence the functional structure of storehouse body from underground air intake duct air inlet.
Preferably, body top, said storehouse is provided with two ventilation and heat passages, and said ventilation and heat passage is arranged on the both sides of smoke exhaust pipe.
The beneficial effect of the utility model is: owing to change forced heat radiation in the storehouse into the natural ventilation radiating mode; Thermal current in the body of storehouse is discharged through the locomotive itself and the ventilation and heat passage of band sound suppressor; Can keep air velocity distribution even; Avoid local temperature too high, the energy consumption that noise reduction measure produces is zero basically, thereby has reached the purpose of energy-saving and emission-reduction.This energy-saving and emission-reduction mode greatly reduces the energy consumption that its noise reduction facility produces, and the maintaining workload of noise reduction facility is significantly reduced, and has reduced staff's labour intensity.The noise reduction in this diesel locomotive waterr rheostat test noise reduction storehouse can satisfy the requirement of Standard of Environmental Noise.

Fig. 2 is the plan structure synoptic diagram of Fig. 1.
Fig. 3 is the structural representation of A-A among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail.
The noise reduction of diesel locomotive waterr rheostat test shown in Fig. 1～3 storehouse comprises the track 2 of storehouse body 1, storehouse body 1 bottom and the smoke exhaust pipe 3 at storehouse body 1 top, along both side is provided with underground air intake duct 4 at track 2.Be provided with the cover plate 8 of iron railings structure above the underground air intake duct 4.The end of underground air intake duct 4 is provided with sump 7.Body 1 top in storehouse also is provided with two ventilation and heat passages 5, and ventilation and heat passage 5 is arranged on the both sides of smoke exhaust pipe 3.Ventilation and heat passage 5 is provided with sound suppressor 6.
The course of work of the utility model is following:
As shown in Figure 3, locomotive carries out 5 contrapositions of ventilation and heat passage after entering the storehouse through track 2, and smoke exhaust pipe 3 contrapositions insert testing equipment then, close the gate of storehouse body 1, carry out waterr rheostat test.In the waterr rheostat test; Required fresh air is from underground air intake duct 4 air inlets, and the flue gas that locomotive is produced is in test discharged from smoke exhaust pipe 3, and the thermal current in the body of storehouse is discharged through the ventilation and heat passage 5 of locomotive itself and band sound suppressor 6; Can keep air velocity distribution even, avoid local temperature too high.After test finishes, open the gate of storehouse body 1, locomotive gets into reorganizes and outfit field or maintenance storehouse.When the water quality variation in the storehouse body 1, sewage is discharged from sump 7.
