Description
Technical field
The present invention relates to a kind of temperature measuring equipment of the materials such as grain and oil of storing in a warehouse, or rather, the present invention relates to a kind of cable for measuring temperature assembly of grain information monitoring system.
Background technology
Consult Fig. 1, grain information monitoring system is the necessary equipment of modern grain and oil storage, and major function is for measuring the cereal temperature in silo.Grain information monitoring system has national sector standard.Grain information monitoring system is mainly by computing machine, extension set, the large ingredient of cable for measuring temperature assembly three; The cable for measuring temperature assembly of grain information monitoring system is mainly comprised of some identical cable for measuring temperature, some identical branch line and the main lines of structure of structure again.In figure, shown that cable for measuring temperature assembly is by be disbursed from the cost and expenses line and often show N root cable for measuring temperature and form of main line, a M.
From figure, we are not difficult to find out, cable for measuring temperature assembly is the important component part of grain information monitoring system, and, in the middle of the practical application of grain information monitoring system, the grain heap that each cable for measuring temperature in cable for measuring temperature assembly need to be inserted directly in silo is inner, therefore, the overall mechanical properties of cable for measuring temperature assembly and electric property directly determine the reliability of grain information monitoring system.
Consult Fig. 2, the cable for measuring temperature in current cable for measuring temperature assembly mainly by cable for measuring temperature wire, temperature sensor and encapsulation thereof, the metal collar, send into noose etc. and form; Branch line by No. 1 connector syringe needle, No. 2 connector syringe needles ..., N connector syringe needle, No. 1 branch line wire, No. 2 branch line wires ... 2N branch line wire, No. 1 splitter, No. 2 splitters ..., N splitter, No. 1 connector hole head, No. 2 connector hole heads ... the first-class composition in N connector hole.By the patching of the patching of No. 1 connector hole head and No. 2 connector syringe needles, No. 2 connector hole heads and No. 3 connector syringe needles ...., the patching of N-1 connector hole head and N connector syringe needle, realize the assembling that each lists cable for measuring temperature.
When adopting branch line that cable for measuring temperature that some structures are identical, some structures are identical and main line to connect to form cable for measuring temperature assembly, main line connects also will adopt a series of main line connector syringe needle, main line splitter, main line wire, main line connector hole head, adopts the method for each line of being disbursed from the cost and expenses of assembling to can be assembled into main line.Current cable for measuring temperature assembly is all to adopt this kind of loaded down with trivial details method.
Consult Fig. 1 to Fig. 3, at present this kind of method the production of grain information monitoring system, use and keep in repair in there are some problems, its main manifestations be cable for measuring temperature assembly mechanical property not by force, easily impaired, cause the reliability of system low, electric property also just cannot guarantee, therefore, the failure rate of grain information monitoring system is higher; Raw materials cost, manufacturing cost, use cost and maintenance cost are also higher.End is got up, and current cable for measuring temperature assembly subject matter is as follows:
1. the configuration design of the insulating coating of current cable for measuring temperature wire is reasonable not, and the cross-sectional area of insulating coating is larger, causes wasting insulating material; And when cable for measuring temperature when inserting in the graininess such as grain or powdered substance, the resistance of insertion is larger;
2. while keeping in repair grain information monitoring system, can not use the on-the-spot single-point that carry out temperature sensor to change at grain information monitoring system, and must change the cable for measuring temperature of whole at the temperature sensor place of breaking down, maintenance cost be high;
3. branch line and main line all adopt the generic connectivity wire compared with low-tension, and with the identical connector syringe needle of several structures, connector hole head and the identical connections such as splitter of several structures that several structures are identical, physical strength is low, and stretching resistance is little; Simultaneously, splitter that the connector hole head that the connector syringe needle that several structures are identical, several structures are identical and several structures are identical etc. is easily by the corrosion of the environmental factors such as fumigating medicine of grain insect pest, grain information monitoring system reliability is low, cause grain information monitoring system failure rate high, maintenance cost is high.
4. silo is filled after grain, all cable for measuring temperature of cable for measuring temperature assembly need to be inserted into each inner temperature measurement location of grain heap.The way of inserting is to adopt the metal hanger that inserts Metallic rod top to catch on the noose of sending into of (or Metallic rod top groove withstands) cable for measuring temperature lower end, simultaneously, adopt artificial or mechanical method to insert Metallic rod in grain heap, until cable for measuring temperature is inserted into predetermined depth location, insertion Metallic rod is extracted, cable for measuring temperature is just stayed the predetermined depth position of grain heap again.And so forth, cable for measuring temperature is one by one inserted into each inner temperature measurement location of grain heap.Because the noose of sending into of current cable for measuring temperature is all to adopt to suppress and form with the metal collar after 180 ° of steel wire wire wraparounds in two steel wire wires of cable for measuring temperature wire, and another root steel wire wire is cut short, (two steel wire wires are the two poles of the earth of temperature sensor, between them, need insulation, can not short circuit), therefore, the insertion pulling force of cable for measuring temperature only has a steel wire wire in whole cable for measuring temperature to bear, and metallic sheath rim bearing carries pulling force also large (all inserting pulling force carries by metallic sheath rim bearing), above-mentioned reason causes the physical strength of sending into noose of current cable for measuring temperature low, the pulling force of carrying is little, the metal collar is also easily impaired.
