Description
Technical Field
The utility model discloses possibly relate to technical field such as radiation dose detection, range unit's application, in particular to non-contact range finding location surface contamination detector.
Background
JJG478-2016 [ alpha, beta surface contamination Instrument test protocol ]: the standard measurement distance α is 5mm and the standard measurement distance β is 10 mm. In practical practice, the measurement distance of the surface contamination detector is generally required to be kept between 5mm and 10mm in order to ensure the measurement accuracy of the α and β activities at the same time. In the prior art, two methods are mainly used for ensuring the distance between a surface pollution detector and a measured surface. One method is to judge through experience or eye observation, the method is greatly influenced by the operation skill of personnel and the space of a site, and because the measurement distance is only 5-10mm, the surface pollution detector is easily contacted with the measured surface due to improper operation, so that parts are damaged or are polluted by radioactivity, the other method is to install a positioning column on the surface pollution detector, the height of the positioning column is adjusted according to the requirement, during measurement, 4 supporting legs of the positioning column are completely contacted with the measured surface, the method can always keep the measurement distance, but the positioning column needs to be installed before operation every time, after the use is finished and the positioning column is disassembled, the operation and the use are inconvenient, the radioactive pollution is easily diffused, and in addition, when the surface of soft surfaces of clothes, plastic films and the like or the surface of precision instruments and equipment is measured, the positioning column cannot be applied.
Disclosure of Invention
The utility model provides a technical problem: the surface pollution detector is convenient and quick to use, accurate in measurement result and good in safety.
The technical scheme of the utility model: the utility model provides a non-contact range finding location surface contamination detector, the detector include distancer and detector, install a plurality of distancers on the detector, the work reference surface of detector with the work reference surface of distancer is parallel.
Preferably, at least one distance meter is mounted on the probe.
Preferably, the working reference plane of the detector and the working reference plane of the range finder are located in the same plane.
Preferably, a distance indicator lamp is arranged on the distance measuring instrument.
Preferably, the detector further comprises a display controller, and the display controller is electrically crosslinked with the distance meter and the detector.
Preferably, the detector further comprises a handle, and a power supply is installed in the handle.
Preferably, the range finder is a laser or infrared or ultrasonic range finder.
Preferably, the detector is a radiation dose detection device.
The utility model has the advantages that:
1. the surface pollution detector does not need to be in contact with the surface to be detected, does not need to be disassembled and assembled, does not need to be cleaned by decontamination, and is convenient to operate and use.
2. The distance between the surface pollution detector and the measured surface can be kept within a specified range, and the measurement precision is improved.
3. The device is suitable for measuring hard and soft surfaces, the internal surfaces in narrow space and the surfaces of precision instruments and equipment.

Detailed Description
The non-contact distance measuring and positioning surface pollution detector provided by the embodiment comprises a distance measuring instrument 1, a detector 2, a display controller 3 and a handle 4. 1 symmetry of distancer is installed around the detector frame, and its lower edge is along the parallel and level with detector 2, the distancer is totally 4, and every distancer includes range unit and 2 LED pilot lamps, and wherein 1 is the red light, 1 is the green light. The detector comprises an alpha induction component, a beta induction component and a signal conversion component. Display accuse ware 3 is responsible for controlling distancer 1, detector 2, display the accuse ware and include the control unit, data processing and memory cell, display screen, control button and data transmission interface. The battery is housed within the handle 4 of the meter.
A low-power high-precision distance meter is adopted, the maximum measuring distance is 50mm, and the measuring precision is 1 mm; a high-sensitivity detector of 170cm2 is adopted, so that alpha and beta can be simultaneously monitored; 2G high-capacity data automatic storage Flash is selected, and measurement data can be stored for more than 6 months; a universal USB interface is equipped to realize the data communication function with a computer; the number 5 battery or the rechargeable lithium battery is adopted for power supply, and the battery can be continuously used for more than 12 hours after being charged once.
When the non-contact distance measuring and positioning surface pollution detector provided by the embodiment is used, the non-contact distance measuring and positioning surface pollution detector is close to the measured surface, and if the measured distance is within a set interval value, a green lamp on the distance measuring instrument is turned on to prompt that the measured distance is correct; if the distance is less than the lower limit of the set interval, the red light on the distance meter is on, and the display controller sends out an alarm prompt tone; if the distance is larger than the upper limit of the set interval, the red light and the green light on the distance meter are not lighted.
