Due to reasons such as tank car manufacturing process, errors, the actual volume value of each tank car and volume corresponding to same electrolyte level are different.Before each tank car manufacture is dispatched from the factory, must examine and determine through volume measurement, and the tank car of volume measurement assay approval is provided to loading table, the volume table number of corresponding loading table is coated with and beats the assigned address at tank body.
For safety of railway traffic, when loading the dangerous liquid goods such as diesel oil, gasoline, crude oil, cooking oil, heavy chemicals, the loaded weight of goods must not be greater than the load carrying ability of tank car mark, must leave expansion space simultaneously, the volumetric quantity upper limit that regular general cargo loads must not be greater than 95% of tank body mark volume, and lower limit must not be less than 83% of mark volume.
At present, in liquid class tank car shipment, control the shipping amount of goods by controlling the height of pot liquid, what the measurement of pot liquid height adopted is manual method.The method is to open manhole cover, puts into special-purpose dipping, reads electrolyte level on dipping, by volume table number, finds loading table, calculates actual load volume.This actual load volume is also for the handing-over of material.But there is following defect in this kind of method of measurement: tank car is during the liquid dangerous freight of transportation, can in tank, evaporate hazardous gas, survey crew is when opening manhole cover, hazardous gas easily damages human body, also to environment, therefore the safety precaution of survey crew is had to higher requirement; The method result of a measurement of manual read's scale is affected by human factors, and error in reading is larger, and goods handing-over both sides are because the difference of take off data is easily controversial separately.
Summary of the invention
The purpose of this utility model is exactly to overcome the defect that prior art exists, provide a kind of easy to operate, measured error is little and can guarantee the liquid class tank car volume intelligent metering device of staff's safety.
For achieving the above object, the liquid class tank car volume intelligent metering device that the utility model is designed, comprise the sensor installation seat that is arranged on tank body top, its special character is: on described sensor installation seat, be respectively arranged with the distance measuring sensor for detection of liquid level situation in tank body, temperature sensor and pressure sensor, described distance measuring sensor, the signal output part of temperature sensor and pressure sensor is connected with the signal input part of data handler by signal transmission feeder, the signal output part of described data handler shows that by communication cable and hand-held the input end of storage element is connected.
Further, described hand-held shows that the mouth of storage element is also connected with extraneous computing machine or other system control equipment by the PORT COM arranging on communication cable.Like this, can conveniently connect other handheld devices or computing machine.
Further, described distance measuring sensor periphery is provided with splashproof sheath, and described splashproof sheath is fixed in the mounting hole on sensor installation seat.Can prevent that like this distance measuring sensor is impaired when measuring.
Further, described data handler is arranged in connection box, and described connection box is fixed on sensor installation seat.Like this, normal work that can protected data treater, prevents from damaging etc.
Further, described sensor installation seat is arranged on tank body top center line place.Like this, can guarantee the accuracy of take off data.
Principle of work of the present utility model is such: while filling liquid in tank body, liquid level in tank raises, with distance measuring sensor, detect the vertical distance of liquid level and tank deck, with temperature sensor, detect the temperature in tank, with pressure sensor, detect the pressure in tank, by two data below, the vertical distance of liquid level and tank deck is carried out to correction-compensation, obtain the actual height of liquid containing, then by the loading table of vehicle, converse the actual volume amount of vehicle loading liquid.
The utility model has the advantage of: designed liquid class tank car volume intelligent metering device can show the volumetric quantity of loading in real time, while reaching nominal volume amount, show in time, effectively avoided the underload of vehicle cargo or overload to occur, thereby the economic loss that has significantly reduced shipper, has guaranteed transportation safety.Meanwhile, this apparatus structure is simple, simple operation, and maintenance is convenient, is applicable to the surveying work at all kinds of loading liquid goods scene.
