Description
Technical field
The utility model relates to locomotive field of measuring technique, is specifically related to a kind of front-end acquisition device of locomotive fuel oil oil mass.
Background technology
According to National Standard of the People's Republic of China's " prtro-chemistry engineering " GB/T 1885-1998, for " crude oil, lubricating oil and other liquid petroleum product ", first the pseudodensity at a certain temperature must be converted into standard density, again according to standard density, converse the volume-correction coefficient being adapted to standard volume.The locomotive fuel oil volume of different temperatures different densities could be converted into standard volume like this.Unusual trouble in measuring process, can not realize real-time measurement.
The utility model patent " a kind of sensing node device of locomotive fuel oil oil mass " of the applicant's earlier application, the patent No. is: ZL201320278290.7, and need 2 pressure transducers, cost is higher; As long as the utility model pressure transducer just can realize the collection of oil mass.
Utility model content
Technical problem to be solved in the utility model is that providing a kind of does not change the structure of locomotive fuel oil fuel tank, utilizes a fuel tank manhole, installs locomotive fuel quantity harvester, and only needs a pressure transducer, reduce cost.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of locomotive fuel oil oil mass harvester, be placed in fuel tank manhole, comprise the housing that has inner chamber, edge is provided with pilot hole on the housing, corresponding with the original mounting hole of manhole, for harvester is arranged on fuel tank; Need sealing gasket be added during dress, make fuel oil can not from installation site seepage; Described housing upper is provided with upper cover, battery compartment is provided with in described housing, in described battery compartment, battery is installed, be provided with wiring board in described housing, described wiring board is connected in housing by holding screw, is also provided with through hole and blind hole at described housing inner bottom part, it is characterized in that: a pressure transducer is installed in described through hole, be provided with temperature sensor in described blind hole, the fuel oil in described housing cavity and fuel tank is isolated, and described housing cavity is consistent with extraneous air pressure.
Described upper cover inner face connects rubber blanket, is connected to housing upper, is covered by housing by fastening bolt, and described upper cover uses nylon material to make.
Described upper cover some exceed the mounting plane of harvester, the inside of the raised area is provided with antenna, and a hole is arranged at the bottom of described upper cover, fills filtering material in hole.
Described pressure transducer adopts nut, spring pad and red copper pad to be fixed in through hole.
Described wiring board applies three anti-paints.
The intracavity bottom of described housing, casting epoxy resin.
The beneficial effects of the utility model are:
1. need pressure transducer, reduces cost, alleviates the weight of this harvester.
2. upper cover uses nylon material to make, and decreases the shielding of signal.
3. upper cover some exceed the mounting plane of collector, the inside of the raised area fixes up an aerial wire, and makes antenna exceed tank surface as far as possible, decreases the absorption of fuel tank to wireless signal, adds communication distance.
4. a through hole is arranged at the bottom of upper cover, makes the pressure of inner chamber identical with the external world, adds measuring accuracy.
5. wiring board applies three anti-paints, adds the reliability of circuit devcie work.
Accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the utility model vertical view.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
