Specific embodiment
Following explanation is provided to help reader to obtain the comprehensive understanding to method described here, device and/or system.Cause
This, the various change of method described here, device and/or system will be disclosed to those skilled in the art, is changed and equivalent.And
And, it is clear and succinct to increase to save the description to well-known function and construction.
Hereinafter, illustrative embodiments of the invention will be described in detail with reference to the attached drawings.
First, the outdoor examination that the exposure for describing an implementation method of the invention below with reference to Fig. 2 to Fig. 5 accelerates
Test the configuration of equipment.
The open entrance of housing 10 (being provided with artificial light sources lamp 80) be provided with and be formed to open and can
The open and close door 20 of closing, forms sample installation frame 21 to install sample 100 (by sunlight exposure on the preceding surface of open and close door 20
Its state of degrading is tested), support frame 30 is connected by rotary shaft 41 and is supported on the opposite side of open and close door 20,
And motor 40 is installed at any support frame 30 and transmits revolving force to rotary shaft 41 to be engaged by gear.
Here, as shown in Figure 3, it is preferable that install first in the centre of sample installation frame 21, in mutually adjacent position
The pyrheliometer 23 of pyrheliometer 22 and second be used for independent measurement whole radiation energy area (295~2500nm) and ultraviolet region (295~
The amount of radiation energy in 400nm), and install thereunder based on the blackboard temperature of surface temperature by measuring sample installation frame 21
(Black Panel Thermometer, BPT) 24.
Additionally, forming the multiple latch-release cylinders for opening and closing open and close door 20 on housing 10, opposed side wall
50, and housing 10 bottom be connected with pilum 70 via hinge bar 71 and with control housing 10 the anglec of rotation angle control vapour
Cylinder 60 is connected.
Additionally, the rainwater discharge that osculum 12 is used to be externally entering is formed inside housing 10, at bottom margin,
And multiple air blowers 90 are formed at sidewall surfaces so that air forced circulation is so as to control internal temperature.
Meanwhile, detection sensor 15, the closed mode for detecting open and close door 20 are formed in the porch of housing 10, and dash forward
Go out support 25a and 25b to be protruded from open and close door 20 with the corresponding position of detection sensor 15, and the two protrude support 25a
Symmetrical position diagonally to each other is arranged on 25b.
Various types of lamps can be used as artificial light sources lamp 80, and use metal halide in the present embodiment
Lamp, its by by metal halogen compound added to being made with sending close to the white light of daylight in mercury lamp.
The outdoor examination that exposure below with reference to Fig. 6 to Figure 12 embodiment of the present invention of the description with above-mentioned configuration accelerates
Test the using effect of equipment.
First, it is being exposed in the state of the sample 100 of experiment is fixed to sample installation frame 21, is using angle control
Cylinder processed 60 controls housing 10 to make it have certain angle.
That is, because sample installation frame 21 is exposed to outside, open and close door 20 is closed, in sample installing frame
The sample 100 installed on frame 21 is now in the state as shown in Figure 6 and Figure 7 under daylight.
Meanwhile, can be placed in housing 10 and user by will thereon be provided with the sample installation frame 21 of sample 100
Make illuminator 80 and continue light exposure test at whole night.
That is, as shown in Figs. 8 to 11, open and close door 20 opened due to the driving of latch-release cylinder 50 and with housing 10
It is spaced a distance (Fig. 8), open and close door 20 rotates 180 ° (Fig. 9) due to the driving of motor 40 around rotary shaft 41, and
And sample installation frame 21 is positioned with (Figure 10) corresponding with housing 10 along inner side direction.
In the above state, when open and close door 20 is back to its original position and is closed by the driving of latch-release cylinder 50
When, detection sensor 15 is detected simultaneously by closing and driving artificial light sources lamp 80 by being contacted with prominent support 25a and 25b,
So that the sample 100 set at sample installation frame 21 can continue exposed to ultraviolet light.
Additionally, during artificial light sources lamp 80 is driven, the internal temperature of housing 10 by the ON/OFF of air blower 90 control come
Control, and during the open and close of open and close door 20 possibly into rainwater can be quickly discharged by osculum 12.
Additionally, as night is in the past and to the time being arranged in a control unit in the daytime, driven by ON/OFF and
Rotation driving operates open and close door 20 to be exposed outside with by sample installation frame 21 in mode contrary to the above.
Therefore, the open field test equipment that the exposure of embodiments of the present invention accelerates allows basis to change sample with night in the daytime
The position of product installation frame 21 is realizing continuous light exposure test.
Meanwhile, Figure 13 shows the cross-sectional configuration of housing 10 according to another implementation of the invention, wherein, in shell
The inwall of body 10 sets silver foil 11 with the internally reflected radiation sent from artificial light sources lamp 80, is formed in the inlet portion of housing 10
Buffer pad 13 sets elastomeric spring to absorb the impact caused when open and close door 20 is opened and closed inside buffer pad 13
14 to produce Double spring, and forms mounting groove 16 in the side of housing 10 so that an end of elastomeric spring 14 is mounted
In this and it is supported.
Using above-mentioned configuration, during the opening and closing of open and close door 20 are operated, the impact of the inlet portion of housing 10 and shake
The dynamic pad 13 that is buffered absorbs, such that it is able to prevent from separating the damage of open and close door 20 and sample 100 with sample installation frame 21
Phenomenon.
Especially, due to the double elastic function of elastomeric spring 14 being arranged on inside buffer pad 13, pin is further made
Assimilation effect to shock and vibration is maximized, also, stabilization is supported because elastomeric spring 14 is mounted groove 16, it is possible to anti-
The phenomenon generation that only elastomeric spring 14 bends or deforms.
Further, since in the silver foil 11 that sets of inwall of housing 10, the radiant light sent from artificial light sources lamp 80 can be by
Reflection, the advantage of the enhancing exposure effect that the diffusing reflection such that it is able to realize due to ultraviolet light causes.
The open field test equipment that the exposure of the implementation method of the invention described above accelerates can not only in the daytime but also whole
Night also constantly carries out Degrading experiment to polymeric material sample, so as to have and shorten the test period and realize improving experiment
The advantage of the effect of reliability and reappearance.
Although having been described above and illustrating some specific embodiments, pair it will be appreciated by those skilled in the art that, can
The structure of the open field test equipment accelerated with the exposure to embodiments of the present invention carries out various modifications.
However, the implementation method of this modification is without departing from technical spirit of the invention or scope and should be included in such as institute
In the scope of the present invention limited in attached claim.
It is described above multiple embodiments.It is to be understood, however, that various modifications can be carried out to it.For example, such as
Technology described in fruit carry out in a different order and/or if component in described system, framework, equipment or circuit with
Different modes is combined and/or by other components or its equivalent or supplement, can obtain appropriate result.Therefore, its
His implementation method is also within the scope of the appended claims.
