Abstract
The invention relates to a mechanical monitoring device used in a high-risk environment. The mechanical monitoring device comprises an inlet door and a storage space, wherein an air suction pipe is arranged in the storage space, the air suction pipe is connected with an exhaust pipe, the exhaust pipe is used for exhausting underground gas to the outdoor space through a first cross-flow fan and a first explosion-proof motor, which are mutually connected, and a U-shaped pipe pressure gauge is further mounted on the outer side of the storage space; and water is injected into the U-shaped pipe pressure gauge, the first end of the U-shaped pipe pressure gauge is directly connected with outdoor air, and the second end of the U-shaped pipe pressure gauge is connected with the air suction pipe positioned in the storage space. An axial flow impeller is mounted in the position on the inlet door. As the mechanical monitoring device disclosed by the invention is not electrified, the shortcomings of an electric monitoring device can be made up; and furthermore, the mechanical monitoring device has double guarantees and low cost, can be greatly improved in the safety and be used for monitoring in gas storage environments with various flammable, toxic, harmful or fresh air.
Description
Technical field
The present invention relates to the monitoring technique field of high-risk environment, particularly relate to a kind of mechanical type supervising device that is used for high-risk environment.
Background technology
Along with closing on of forbidding ODS time limit of pacts such as Montreal protocol regulations; CFCs and HCFCs series products are soon with disabled; Be that the used cold-producing medium of used gas-development agent of refrigerator or air-conditioning will be influenced by it all will; And all there is a problem undoubtedly in novel environment-friend substitution product is exactly inflammable and explosive, like cyclopentane, R290 etc.How that stores, stores is exactly enterprise or a problem that the user faced.The at present general method that adopts is to make up a underground tank as storage space, is equipped with blower fan and takes a breath and control concentration, and be equipped with sensor (like concentration, pressure etc.) this storage space is carried out a monitoring, in case the safety problem that the air regenerating device fault causes.But this type of monitor mode needs electrical control, loses if generation outage or equipment malfunction are then monitored to render a service to the greatest extent, so there is huge potential safety hazard.
Summary of the invention
Technical matters to be solved by this invention provides a kind of mechanical type supervising device that is used for high-risk environment, is applied to the storage space under the negative pressure state, solves the security hidden trouble that existing electric monitor mode exists.
The technical solution adopted for the present invention to solve the technical problems is: a kind of mechanical type supervising device that is used for high-risk environment is provided; Comprise entrance door and storage space; Be provided with aspiration channel in the storage space; Said aspiration channel links to each other with exhaust duct, and said exhaust duct is discharged the gas in the storage space through interconnective first cross flow fan and first fire proof motor outdoor, and the said storage space outside also is equipped with U-tube manometer; Be marked with water in the said U-tube manometer, first end directly links to each other with outdoor air, and second end links to each other with the aspiration channel that is positioned at storage space.
Said exhaust duct also is provided with pressure transducer, and said pressure transducer links to each other with second fire proof motor, and said second fire proof motor drives the second cross flow fan work.
Described entrance door place is equipped with axial-flow leaf.
Said U-tube manometer is marked with scale.
Said U-tube manometer second end links to each other with the aspiration channel that is positioned at storage space through flexible pipe.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art has following advantage and good effect: the present invention is not because charged; Therefore remedied the shortcoming of electric supervising device; And adopt two parts to form, and have double shield, realize with low cost; Security improves greatly, can be used for the monitoring of all kinds of inflammable gas storage conditions.

Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present invention relates to a kind of mechanical type supervising device that is used for high-risk environment, like Fig. 1-shown in Figure 4, comprises entrance door, from entrance door 1, through staircase 2, passes ground level 9 and can enter into storage space 10.Be provided with aspiration channel 15 in the storage space 10; Said aspiration channel 15 links to each other with exhaust duct 3; Said exhaust duct 3 is discharged the gas in the storage space 10 through interconnective cross flow fan 4 and fire proof motor 6 outdoor, generally speaking, and cross flow fan 4 and fire proof motor 6 operate as normal; Gas in the storage space 10 is entered outdoor, keep the negative pressure state in the storage space 10.Pressure transducer 14 is equipped with at 3 places at exhaust duct, can record whether operate as normal of exhaust equipment, in case break down, then can open subsequent use cross flow fan 5 automatically and carry out work with fire proof motor 7.Described entrance door 1 place is equipped with axial-flow leaf 8 (see figure 5)s, and this stylish wind can get into through air intake vent 13 and axial-flow leaf 8, because the existence of pressure reduction; Rotate thereby drive axial-flow leaf 8, the expression gas flow is normal, otherwise; Then explanation has equipment failure, has potential safety hazard.Said storage space 10 outsides also are equipped with U-tube manometer 11 (see figure 6)s; Be marked with water in the said U-tube manometer 11; First end directly links to each other with outdoor air, and second end links to each other with the aspiration channel that is positioned at storage space 10 15 through flexible pipe 12, in like manner; If there is pressure reduction in U-tube manometer 11 surface levels, explain that then inflammable gas concentration is in normal condition.Otherwise then explanation has equipment failure, has potential safety hazard.U-tube manometer 11 is marked with scale makes the observer can know at once whether the water surface exists pressure reduction.
Be not difficult to find that therefore the present invention has remedied the shortcoming of electric supervising device, and adopted two parts to form because not charged, has double shield, realize with low costly that security improves greatly, can be used for the monitoring of all kinds of inflammable gas storage conditions.
