Description
Technical field:
The utility model relates to the shading coefficient detector of a kind of probe along circular swing motion, and it belongs to the pick-up unit of the shading coefficient of building external sunshade device.
Background technology:
Sunshade is the emphasis and the key of southern area energy-saving building technology, and the solar radiation that sees through window summer gets the hot 30%-40% that air conditioning energy consumption accounts for the total air conditioning energy consumption of building that consumes.Existing shading product is of a great variety, and quality is uneven, is necessary its shaded effects are detected.
In the existing Chinese patent application number the 200620145309.0th a kind of " sunshade detector " disclosed, constant temperature low-temperature receiver and cold table that it comprises the detector main body, is used to support the rotation regulating mechanism of detector main body, is connected with the detector main body; Its primary structure is: detector main body, the rotation regulating mechanism that is used to support the detector main body, the constant temperature low-temperature receiver that is connected with the detector main body and cold table; Described detector main body comprises standard meter measuring tank, tester measuring tank and protective housing, and described standard meter measuring tank, tester measuring tank place in the protective housing; Fan coil is installed on the inwall of standard meter measuring tank, tester measuring tank and protective housing; The constant temperature low-temperature receiver is connected with fan coil by water pipe.The standard meter measuring tank is positioned at the top of tester measuring tank, and its structure, size, materials are identical.The principle of work of this sunshade detector is " a protective hot box pairing comparision ", is called for short: hot case method.During detection, tested solar protection devices is installed on the window of tester measuring tank, starts fan coil, make the temperature unanimity in two batch meters.Since the existence of solar protection devices, the sun of tester measuring tank get hot will get less than the sun of standard meter measuring tank hot, so the cold that it obtains from fan coil will be less than the cold that the standard meter measuring tank obtains from fan coil.If ignore the motor of fan coil thermal value, ignore the heat that passes away from tank wall and, measure the cold of two fan coils outputs from the outside dispersed heat of casing window, the difference of the two is exactly to be got hot by the sun that above-mentioned solar protection devices covers.And the in fact above-mentioned heat of ignoring all must detect and estimate.Obviously, use hot case method test shading coefficient to exist the experimental provision complexity, can't deficiency such as test to being installed in shading product in the actual building.
The measuring method that adopts the pyranometer pairing comparision is also arranged in the prior art.During detection, a pyranometer is installed in tested solar protection devices back, does not have the place of blocking fully what another piece pyranometer was installed in tested solar protection devices next door.The ratio of the data that two pyranometers record is shading coefficient.It is the total solar radiation of 0.3-3 μ m that pyranometer generally is used for the measure spectrum scope, also can be used to measure the solar radiation of inciding on the inclined-plane, can measure reflected radiation downwards as sensitive surface, as adds shade and can measure scattered radiation.Therefore, it can be widely used in the measurement that solar radiation energy is done by department such as the aging and atmospheric pollution of sun power utilization, meteorology, agricultural, building materials.The conventional using method of pyranometer is to be fixed in a certain position (its response time is 30 seconds, and supplier thinks that he is not suitable for detecting in motion state).The shading coefficient that adopts pyranometer to detect the external sunshade device is thought unfavorable by the insider, because many solar protection devices are the blinds solar protection devices particularly, it is understanding level or vertical stripes shape hot spot light and dark under the exterior window upslide under sunlight direct projection, the spacing of the hot spot that different shading products produce is often inequality, and its spacing and position change along with the variation of solar angle, to be difficult to the influence that the above-mentioned situation of accurate response is brought when adopting fixing pyranometer to test, therefore the data that record often also can't correctly reflect the sunshade situation.
Summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, measure convenient, measurement data accurately, with the shading coefficient detector of the dynamic pyranometer pairing comparision probe that is ultimate principle along circular swing motion.
The purpose of this utility model is achieved in that
A kind of probe is along the shading coefficient detector of circular swing motion, and it comprises base, reducing motor, detection probe, main shaft, reference probe and data collecting instrument, and described detection probe is connected with data collecting instrument by the radiation signal line with the reference probe; It is characterized in that it comprises that also an end is hinged on fork on the base, is arranged on slide block or the linear bearing on the fork and an end is fixed on the main shaft, the other end and the hinged crank of slide block, is connected with a belt gear combination that is driven by reducing motor on described main shaft.
End at described fork is provided with extension rod, and described detection probe is arranged on the extension rod.
Described extension rod is provided with adjustment hole, and described extension rod connects with fork by the adjusting screw that is arranged in the adjustment hole.
Described base is provided with sucker.
Detection probe of the present utility model is moved along the form of circular swing motion, be applicable to the shading coefficient that detects sun-shading louver, its detection probe can be passed through the striated hot spot that light and shade replaces, and so just can overcome the irregular influence that brings of the test zone light and shade that is caused by sun-shading louver.The utility model is simple in structure, reliable, cheap, and detecting operation is flexible, not only it can be installed on the rotation platform solar tracking is detected, and can also the external sunshade product of actual installation in the building be detected, and obtains.Detect the shading coefficient of various external sunshade devices more accurately.
