Abstract
The utility model proposes the simulation teching experimental provision of a kind of tunnel smoke evacuation, comprise the passage body and controller be made up of transparent material, transverse fan is provided with in this passage body, vertical blower fan, temperature-sensing element, smoking device, this temperature-sensing element is connected with temperature indicator, and described controller is electrically connected with described transverse fan and vertical wind machine respectively.The utility model can simulation tunnel smoke evacuation various practical situation, for learner provides a practical operation drilling platforms, facilitate learner to the understanding of entire system and study.
Description
Technical field
The utility model belongs to teaching experimental equipment technical field, is specifically related to the simulation teching experimental provision of a kind of tunnel smoke evacuation.
Background technology
Tunnel smoke evacuation system is made up of smoke exhaust fan, blower fan tunnel, heat detector, its feature is when tunnel breaking out of fire accident, start smoke exhaust fan, smog in tunnel is discharged outside tunnel, for personnel, vehicle dispersal and fire fighting and rescue personnel provide fresh air, and form good airflow circulating.
At present, the main mode of learning of this systematic knowledge and technology is: one is grasped by theories of learning principle knowledge and system diagram, due to theoretical property, nature static, the non-intuitive of written knowledge, make learner be difficult to grasp system technical details and dynamic state of run, be difficult to reach good results of learning; Two is by field observation, and is grasped by the engineering practice of regular period, and this not easily realizes for students.The experiment device for teaching of tunnel smoke evacuation system is not also had for Students ' Learning and experiment in prior art.
Utility model content
The purpose of this utility model is the simulation teching experimental provision proposing the smoke evacuation of a kind of tunnel, can tunnel that is virtually reality like reality smoke evacuation sight be easy to observation of students.
The technical solution of the utility model is achieved in that the simulation teching experimental provision of discharging fume in a kind of tunnel, comprise the passage body and controller be made up of transparent material, transverse fan is provided with in this passage body, vertical blower fan, temperature-sensing element, smoking device, this temperature-sensing element is connected with temperature indicator, and described controller is electrically connected with described transverse fan and vertical wind machine respectively.
By controlling transverse fan and vertical blower fan respectively, the difference of natural draught system and mechanical smoke extraction in demonstration passage, and the difference of horizontal mechanical smoke extraction and vertical mechanical smoke extraction; The relation of itself and smoke discharging effect is demonstrated by controlling fan delivery; The impact of diverse location on smoke evacuation is demonstrated by the position control of smoking device; By temperature monitoring, demonstration intra passage temperature is on the impact of smoke evacuation.
Further, one end of described passage body is provided with jacking gear.Jacking gear for regulating the degree of tilt of passage body, to demonstrate the impact of the gradient on smoke discharging effect.
The utility model can simulation tunnel smoke evacuation various practical situation, for learner provides a practical operation drilling platforms, facilitate learner to the understanding of entire system and study.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-passage body, 2-transverse fan, the vertical blower fan of 3-, 4-temperature-sensing element, 5-temperature indicator, 6-smoking device, 7-controller, 8-jacking gear.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The simulation teching experimental provision of tunnel smoke evacuation as shown in Figure 1, comprises the passage body 1 and controller 7 be made up of transparent material, is provided with the vertical blower fan of two transverse fans 2,3, three temperature-sensing elements 4 and a smoking device 6 in this passage body 1; Each temperature-sensing element 4 is all connected with temperature indicator 5, for the temperature in display channel body 1; Smoking device 6 can be realized by the prior art such as smoke generator, smoke-pot, also by install combustion platform, is fuming by burn combustible thing; Described controller 7 is prior art, is electrically connected respectively with described transverse fan 2 and vertical blower fan 3, for controlling switch and the open amount of blower fan; One end of described passage body 1 is provided with jacking gear 8, and this jacking gear 8 can adopt machinery or the hydraulic lift of prior art.
During demonstration, smoking device 6 is fuming, and fills cigarette in passage body 1, the smog in passage got rid of by unlatching transverse fan 2 and vertical blower fan 3 respectively, temperature in temperature-sensing element 4 Measurement channel 1 is also shown by temperature indicator 5, regulates jacking gear 8 to observe the change of smoke discharging effect in certain slope.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
