Background technology
The heat fire detector that is used for the fire protection warning industry need test to its performance parameter before dispatching from the factory and test, and uses special tooling device in the test, under the temperature conditions of tooling device simulation, accomplishes the detection of heat detection appearance.This kind checkout equipment that the prior art tradition is used mainly is closed loop incubator and high-low temperature test chamber.This closed loop incubator is generally produced by NFA electronic product quality supervision and test centre punch one, and the advantage of this incubator is the application that is applicable under the multiple temperature rise rate, and shortcoming is bulky, and detection time is long, is not suitable for streamline and uses; Power consumption is high, and maximum power dissipation reaches 8KW; The operating process complicacy is loaded down with trivial details, can't satisfy the constant temperature demand, and adjustment is complicated, and inefficiency is had relatively high expectations to environment temperature, and must be stabilized in 20 ± 5 ℃ just can operate as normal.High-low temperature test chamber can be used for parts and the detection of material each item performance index under the situation of high and low temperature (alternation) circulation change of the Related product of multiple industry.Shortcoming is under the hot test situation, to be not suitable for the frequent chamber door of opening, and frequently opens the door to cause and can't realize that accurate temperature control, circulation of air heat waste are big.
Summary of the invention
The objective of the invention is to overcome the shortcoming that exists in the prior art; Provide a kind of volume little, simple in structure, detect required time on-line measuring device short, that detection sensitivity is high, that be exclusively used in point heat detector; The technical scheme that adopts is: a kind of heat detector on-line measuring device; Comprise housing, it is characterized in that: said heat detector on-line measuring device comprises the mount pad that is positioned at housing, is used to install detector to be detected, is used to detect the temperature monitoring part of temperature in the housing; The intensification and the adjustment part that are used for simulated fire temperature rise situation; Be used to accomplish the warning part of signal feedback, said detector to be detected is connected with the part of reporting to the police, and power supply is the part power supply of reporting to the police.
Technical characterictic of the present invention also has: said intensification and temperature regulation section branch comprise well heater and temperature regulator.
Technical characterictic of the present invention also has: said intensification and adjustment part also comprise fan.
Technical characterictic of the present invention also has: said temperature monitoring partly is a digital thermometer, and the temperature measuring head of this digital thermometer places in the said housing.
Beneficial effect of the present invention is: this monitoring device is a kind of heat fire detector pick-up unit of special use; Base with heat detector during use places on the mount pad; As long as detecting device is reported to the police at the appointed time; Prove that promptly this detector is qualified, compare, the advantage that this pick-up unit has is simple in structure, easy to operate, with low cost, detection speed is fast with the traditional detection device; Especially effectively shorten single detector and detected the used time, be applicable to the online detection before heat detector dispatches from the factory.
Description of drawings
Accompanying drawing 1 is a front view of the present invention, and accompanying drawing 2 is vertical views of the present invention, and accompanying drawing 3 is that circuit connects synoptic diagram, wherein, the 1st, housing; The 2nd, fan door, the 3rd, pilot lamp, the 4th, pilot lamp mount pad, the 5th, fan, the 6th, mount pad; The 7th, detector to be detected, the 8th, well heater, the 9th, power supply door, the 10th, control panel; The 11st, power supply, the 12nd, temperature regulator, the 13rd, digital thermometer, the 14th, temperature measuring head.
Embodiment
Below in conjunction with accompanying drawing, the present invention is specified.This pick-up unit designs based on point heat detector, and this point type heat fire detector uses NTC type thermistor as detector unit, and NTC type thermistor has the characteristic that resistance raises and reduces gradually with temperature.Can obtain temperature variant voltage through electric resistance partial pressure, carry out the AD conversion behind this voltage input CPU, after calculating, can draw current environmental temperature.CPU carries out continuous sampling to environment temperature, calculates the temperature and the heating rate of current environment, thereby in official hour, quotes constant temperature fire alarm or differential temperature fire alarm according to heating rate.
In order to realize the purpose of quick online detection; The invention provides a kind of heat detector on-line measuring device, its concrete structure comprises housing 1, is positioned at housing 1, is used to install the mount pad 6 of detector 7 to be detected; Be used to detect the temperature monitoring part of temperature in the housing 1; Be used for intensification and the adjustment part and the warning part that is used to accomplish signal feedback of simulated fire temperature rise situation, detector 7 wherein to be detected is connected with the part of reporting to the police, and power supply 11 is the part power supply of reporting to the police.
Intensification and adjustment part specifically comprise well heater 8, temperature regulator 12 and fan 5, and wind speed is identical with GB (GB4716-2005), and the purpose that fan 5 is set is to keep the harmony of temperature in the whole housing 1.What temperature monitoring partly adopted is a digital thermometer 13, but places housing 1 interior detection at any time to arrive the temperature in the housing 1 temperature measuring head of this digital thermometer 13.
During use, keep temperature constant in the housing 1, higher 45 ℃ than room temperature all the time, during check, detector 7 to be detected is installed on the mount pad 6, put into this pick-up unit then.According to calculating, qualified detector should be quoted fire alarm in 10S.Use is following:
