Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an environmental test apparatus having an immersion function.
[0002]
[Prior art]
Conventionally, various materials used outdoors such as metal and paint are deteriorated by various environmental factors such as light, rain, condensation, temperature and humidity. In order to accurately reproduce this deterioration, an outdoor exposure test is required in which exposure is performed outdoors only for the years of use in areas where various materials are used. However, the areas where various materials are used are diverse, and the environmental factors in each area are often different. Therefore, a test method for performing tests according to various environmental factors in order with a test apparatus corresponding to each environmental factor, that is, a test method for performing light irradiation test, salt spray test, immersion test, drying test, etc. in a single order. Was adopted.
[0003]
However, in such a test method that combines a single test device, it takes time to test and it is difficult to always move the test sample between the devices under the same conditions. The deterioration (corrosion) could not be reproduced well.
[0004]
In view of this, a so-called combined cycle test apparatus for testing while adding various environmental factors in one apparatus housing has been developed and used (see, for example, Japanese Patent Application Laid-Open No. 7-20035).
[0005]
On the other hand, countermeasures have been sought when there is an explosion risk due to abnormally high temperatures in the specimen under test according to environmental factors.
[0006]
As a countermeasure, it is conceivable that water is introduced into the apparatus housing when the specimen is heated, ignited or smoked, and the specimen is immersed. As such, when the specimen is heated, ignited or smoked, a large amount of water must be used in order to completely immerse the specimen and quench it. It is conceivable to increase the depth of the immersion bat so that it can be accommodated.
[0007]
[Problems to be solved by the invention]
However, in the apparatus as described above, since the specimen is placed in the immersion bat and a series of tests are performed, as described above, when the immersion bat is deepened, It becomes difficult to put in and take out the sample.
[0008]
This invention is made | formed in view of this point, and it aims at providing the environmental test apparatus which can perform rapid cooling operation in an emergency, without making taking in and out of a specimen difficult.
[0009]
[Means for Solving the Problems]
An environmental test apparatus according to the present invention is an environmental test apparatus for performing an environmental test related to temperature, humidity, pressure, gas, liquid, etc., and an apparatus housing having an article entrance and an article entrance of the apparatus housing are closed so as to be openable and closable. An article entry / exit door, a watertight tank provided inside the apparatus housing so as to be able to enter / exit through the article entry / exit and having an opening formed in a vertical wall corresponding to the article entry / exit, and the watertight tank in the apparatus housing A water-injecting means disposed above the water-tight tank and capable of pouring water into the water-tight tank; and a water-tight plate that closes an opening of the water-tight tank, and the water-tight plate is supported by the article access door. And a watertight operation means that alternatively takes the second state of closing the opening of the watertight tank in a watertight manner. Here, the watertight tank may be an integral structure with the apparatus housing, or may be a separate structure so that it can be carried out of the apparatus housing. The opening may be a so-called large hole, or it may be a notch that is partially open, and if it has a size that allows the sample to be taken in and out, Is not particularly limited. Furthermore, the switching between the first state and the second state by the watertight operation means may be performed by manual operation of the operator, or some signal (for example, an immersion signal, a rapid cooling signal, or an emergency signal) is input. It may be automatically performed at the time.
[0010]
Therefore, in a normal state, the watertight plate is in the first state supported by the article entrance door by the watertight operation means. Therefore, if the article entrance door is opened to open the article entrance, the watertight board Can be opened together. At this time, the opening of the watertight tank is not closed by the watertight plate and is open. For this reason, the specimen can be freely taken in and out of the watertight tank through the opening, and the specimen can be easily taken in and out regardless of the depth of the watertight tank.
[0011]
On the other hand, at the time of immersion or rapid cooling, the watertight plate is brought into a second state in which the opening of the watertight tank is closed in a watertight manner by the watertight operation means. In this state, the water-tight tank is filled with water by the water injection means, so that the specimen can be completely immersed or rapidly cooled.
[0012]
Further, the watertight tank has a side wall and a bottom wall so as to form a double wall inside the apparatus housing, and a moving means is provided on the lower surface of the bottom wall so that the watertight tank can be moved. For example, the watertight tank can be carried out from the inside of the apparatus housing, which is convenient.
[0013]
If the specimen is immersed when it is heated, ignited or smoked, it cannot be drained until it is completely cooled down and it can be confirmed that no abnormality will occur again. If a moving means is provided as described above, a separate watertight tank for storing abnormal products (test samples) in the immersed state is taken out of the device housing as long as a separate watertight tank is prepared. By carrying in the spare watertight tank instead of the above, it becomes possible for the test apparatus to perform a similar test on another specimen. In this case as well, it is necessary to support the watertight plate for the spare watertight tank on the article access door. In particular, if the water-tight plate is formed of a transparent material, it is convenient to see the internal state when it is carried out of the apparatus.
[0014]
The watertight operation means is provided on the article entrance door and is provided on the watertight tank side with a plurality of support members capable of supporting appropriate portions of left and right side edges or lower edges of the watertight plate, and the support The support of the watertight plate by the member is released, and the opening can be closed by attracting to the watertight tank side, and a watertight holding member that can hold the state can be provided.
[0015]
If it does in this way, a watertight board will be stably supported by the door for goods entrance / exit by supporting the suitable location of the right-and-left side edge part or lower edge part of a watertight board normally by a plurality of support members. (First state). On the other hand, at the time of immersion or rapid cooling (emergency), the support of the watertight plate is released by the watertight holding member, and then the released watertight plate is attracted to the watertight tank side, and the opening is opened by the watertight plate. The part is closed watertight (second state). By pouring water into the watertight tank in a state where the opening of the watertight tank is watertightly closed by the watertight plate, it becomes possible to completely immerse the specimen or to quench it with a large amount of water.
[0016]
The watertight holding member has an inclined surface that contacts the right and left side edges or the lower edge of the watertight plate and moves the watertight plate obliquely upward toward the watertight tank, and the watertight tank has the opening A stopper for restricting the upward movement of the watertight plate can be provided above both sides of the portion.
[0017]
In this way, it is possible to easily move the watertight plate obliquely upward toward the watertight tank side by using the inclined surface, and the stopper restricts the upward movement of the watertight plate. By doing so, the watertight plate is stopped at a predetermined position in relation to the stopper, and the watertight plate is brought into a state of being watertightly crimped to the periphery of the opening of the watertight tank.
[0018]
Furthermore, the water injection means may include a water storage tank provided on the upper side of the device housing.
[0019]
If there is no water storage tank, it is necessary to supply water by pumping from tap water or another tank, and it will take time to soak, but it is necessary to install a water storage tank on the upper side of the device housing. It is possible to drop the water inside the watertight tank at once, without using a pump, and to inject water, which is very effective as a rapid cooling operation.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0021]
FIG. 1 is a diagram showing a schematic configuration of an embodiment of an environmental test apparatus having an immersion function and incorporating a watertight tank that can be carried out.
[0022]
In FIG. 1, reference numeral 1 denotes an environmental test apparatus for performing an environmental test related to temperature, humidity, pressure, gas, liquid and the like. Inside the apparatus housing 2 of the environmental test apparatus 1, a box-shaped watertight tank 3 having an open upper surface and a deep depth is disposed so as to be removable.
[0023]
An article entry / exit 4 having a size that allows the watertight tank 3 to be taken in / out is formed on the front wall of the apparatus housing 2, and the article entry / exit 4 is closed by an article entry / exit door 5 so as to be opened and closed. ing. The article entry / exit port 4 also functions as an opening for taking in / out the sample to / from the watertight tank 3.
[0024]
Moreover, the inside of the apparatus housing 2 is divided up and down by a ceiling plate 8 having an air outlet 6 and an air intake 7, and the upper side of the ceiling plate 8 is the temperature, humidity and test in the apparatus housing 2. A humidity control chamber 9 for adjusting the surface temperature is used, and a lower side of the ceiling plate 8 is a test chamber 10 in which an environmental test is performed. A filter 61 is provided at the air outlet 6.
[0025]
The temperature control / humidity control chamber 9 is provided with a cooler 11, a heater unit 12, and a fan 14 that is rotationally driven by an outdoor motor 13 in that order from the air inlet 7 side toward the air outlet 6 side. Yes. Then, the air in the test chamber 10 is sucked by the fan 14, adjusted to a predetermined temperature and humidity in the temperature control and humidity chamber 9, and blown into the test chamber 10 at a predetermined wind speed, and the inside of the test chamber 10 is predetermined. The surface of the specimen in the watertight tank 3 is held at a predetermined temperature.
[0026]
Below the air outlet 6 of the ceiling plate 8, the air temperature-controlled and humidity-controlled in the temperature-controlled humidity control chamber 9 can be blown as uniformly as possible to each sample in the watertight tank 3. Further, a louver 15 for adjusting the wind direction is attached.
[0027]
A plurality of water injection nozzles 16 are provided below the ceiling plate 8 and below the louver 15 for dipping operation or rapid cooling operation. The water injection nozzle 16 is located above the watertight tank 3 and is arranged so that water can be injected into the watertight tank 3.
[0028]
On the other hand, the watertight tank 3 has a rectangular bottom wall 21 and four vertical walls 22, 23, 24, and 25 that are connected to the periphery of the bottom wall 21 and extend substantially vertically upward. Of the four vertical walls 22 to 25, a rectangular notch 26 (opening) opened upward is formed in the vertical wall 22 at a position corresponding to the article entrance / exit 4 of the device housing 2. Yes. Further, an exhaust partition wall 27 is provided inside the vertical wall 24 opposite to the vertical wall 22 so as to constitute an exhaust passage 28 through which air flows from the lower side to the upper side. A concave portion 29 that functions as a humidifying dish is formed in a portion of the bottom wall 21 that faces the lower end of the exhaust partition wall 27.
[0029]
Between the article access door 5 and the watertight tank 3, a watertight operation means 32 having a watertight plate 31 that closes the notch 26 of the vertical wall 22 in the watertight tank 3 is disposed. The watertight operation means 32 is specifically configured as shown in FIGS. 4 and 5, and a first state (see FIG. 4) in which the watertight plate 31 is supported by the article access door 5 and the watertightness. The second state (see FIG. 5) in which the notch portion 26 of the tank 3 is closed in a watertight manner is alternatively set.
[0030]
As shown in FIG. 2, packing 33 is provided on the outer peripheral edge of the notch 26, and when the notch 26 is closed by the watertight plate 31, the watertight plate 31 is watertight against the watertight tank 3. It is comprised so that it may be crimped | bonded to. Further, as will be described later, a protruding portion 34 that functions as a stopper that restricts the upward movement of the watertight plate 31 is provided at the upper end of the left and right side portions of the cutout portion 26, so that the watertightness can be more reliably ensured. I am doing so.
[0031]
Below the bottom wall 21 of the watertight tank 3, casters 35 (moving means) are provided at four corners so that the watertight tank 3 itself can be moved. Therefore, the watertight tank 3 can be easily taken in and out of the apparatus housing 2 through the article entrance 4.
[0032]
The watertight operation means 32 is provided on the indoor side of the article access door 5 and supports a plurality of support members 41A that can support appropriate portions of the right and left side edges of the watertight plate 31 and appropriate portions of the lower edge. A plurality of support members 41B that are possible and provided outside the watertight tank 3, and when necessary, the support of the watertight plate 31 by the support members 41A and 41B is released, and the watertight plate 31 that has been released from the support is released. The notch portion 26 is closed by pulling to the side 3, and the watertight holding members 42A and 42B that can hold the watertight plate 31 in that state are provided. Therefore, normally, by opening the door 5 for entering and exiting the article, the specimen can be freely put into and taken out of the watertight tank 3 through the notch 26, and a watertight tank having a completely watertight structure only when necessary. And will be able to.
[0033]
Specifically, as shown in FIG. 4, the support members 41A and 41B include shaft portions 43A and 43B that are rotatably supported by the boss portions 5a and 5b of the article access door 5, and the shaft portions 43A and 43B. 43B has inner and outer support portions 44A, 44B and 45A, 45B which are fixed with a gap slightly wider than the thickness of the watertight plate 31 and have different heights in the circumferential direction, and both the support portions 44A, 44B. In addition, by sandwiching a plurality of locations on the left and right side edge portions or the lower edge portion of the watertight plate 31 between 45A and 45B, the watertight plate 31 is detachably supported. That is, since both the support portions 44A, 44B and 45A, 45B have different heights in the circumferential direction, when the support members 41A, 41B are rotated and come to a portion where the height is low, the water-tight plate 31 is supported. Is to be canceled.
[0034]
On the other hand, the watertight holding members 42A and 42B are rotatably provided on the watertight tank 3 side corresponding to the support members 41A and 41B, and are rotatably supported by a boss portion (not shown) of the watertight tank 3. Shaft portions 46A and 46B, and operation portions 47A and 47B that are provided at the tips of the shaft portions 46A and 46B and can support the watertight plate 31 released from the support. Since the watertight holding members 42A and 42B are partly in contact with the corresponding inner support portions 44A and 44B, the operation portions 47A and 47B (watertight holding members 42A and 42B) are rotated to rotate the inner support portions. The entire support members 41A and 41B can be rotated via the portions 44A and 44B, and the support of the watertight plates 31 of both the support portions 44A and 44B and 45A and 45B can be released as described above. The watertight plate 31 released from the support is lifted and supported by the inclined surfaces 48A and 48B of the operation portions 47A and 47B.
[0035]
The inclined surfaces 48A and 48B have a guide surface shape for moving the watertight plate 31 obliquely upward toward the watertight tank 3 side. When the watertight plate 31 is moved obliquely upward toward the watertight tank 3, the watertight plate 31 collides with the protrusion 34 in the upper part of the watertight tank 3, and the upward movement of the watertight plate 31 is restricted. As a result, the watertight holding members 42 </ b> A and 42 </ b> B hold the state where the watertight plate 31 is crimped to the peripheral edge of the cutout portion 26 of the watertight tank 3. As described above, since the watertight plate 31 must be moved obliquely upward in order to press the watertight plate 31 to the periphery of the cutout portion 26 of the watertight tank 3, the top of the watertight plate 31 supported by the article entry / exit door 5 is used. A clearance L for operation is provided between the edge portion and the protruding portion 34.
[0036]
If comprised as mentioned above, the watertight board 31 will be pinched | interposed between inner side support part 44A, 44B and outer side support part 45A, 45B in the normal state, and is supported by the door 5 for goods in / out. Therefore, in this state, the notch 26 of the watertight tank 3 is opened.
[0037]
In the state where the notch portion 26 is opened, even if the article entrance door 5 is opened, even if the depth of the watertight tank 3 is deep, the test article can be placed inside the notch portion 26 through the notch portion 26. It can be done easily.
[0038]
On the other hand, in the case of an emergency in which the specimen is heated, ignited or smoked during the test, it is necessary to close the notch 26 and make the watertight tank 3 into a watertight structure for soaking. To remove the watertight plate 31 from the article entry / exit door 5 and close the notch 26.
[0039]
That is, by rotating the watertight holding members 42A and 42B and rotating the support members 41A and 41B with an operation handle (not shown), the support of the watertight plate 31 by both the support portions 44A and 44B and 45A and 45B is released. The watertight plate 31 is moved onto the inclined surfaces 48A and 48B of the operation portions 47A and 47B and supported by the watertight holding members 42A and 42B. Then, by continuing further rotation, the watertight plate 31 moves obliquely upward toward the watertight tank 3 side while the right and left side edges and the lower edge of the watertight plate 31 are guided along the inclined surfaces 48A and 48B. Finally, it contacts the protrusion 34 in the upper part of the watertight tank 3, and further movement is restricted. At this time, the watertight plate 31 is pressure-bonded to the peripheral edge portion of the notch portion 26 via the packing 33. Thus, the watertight tank 3 having a deep watertight structure in which only the upper surface portion is opened and the upper end portion reaches the vicinity of the ceiling plate 8 is formed. In this state, the watertight plate 31 is supported on the watertight tank 3 side via the operation portions 47A and 47B (watertight holding members 42A and 42B).
[0040]
In this state, water is supplied from the tap water or the storage tank to the water injection nozzle 16 by a pump, the water is injected into the watertight tank 3, the specimen is completely immersed, and rapid cooling is performed. In this case, since the watertight tank 3 has casters 35, the watertight tank 3 including the specimen under abnormal condition is taken out of the apparatus housing 2, and a spare watertight tank is used as a test apparatus. Different tests can be performed on different specimens. Therefore, it is not necessary to play the environmental test apparatus 1 even if the test sample is heated, ignited or smoked.
[0041]
In addition, not only during rapid cooling, but also in the case where a normal immersion test is performed, such as a battery immersion test in the safety evaluation standard of the battery (SAB G 1101), if a watertight structure is similarly used, It is possible to perform an immersion test in which the product is completely immersed. Further, since the depth of the watertight tank 3 can be increased, the immersion test can be performed even if the specimen is large.
[0042]
Although one embodiment of the environmental test apparatus of the present invention has been described above, the present invention is not limited thereto, and various modifications can be made as exemplarily shown below.
[0043]
(1) Although water supplied by a pump from a tap water or a water storage tank is injected into the watertight tank 3 using the water injection nozzle 16, it takes time to soak the water. Therefore, for example, as shown by a chain line in FIG. 1, a water storage tank 51 is provided on the upper side of the apparatus housing 2, and an open / close valve (not shown) is provided in the middle of the pipe connecting the water storage tank 51 and the water injection nozzle 16. At the time of rapid cooling, by opening the on-off valve, water can be dropped into the watertight tank 3 having a watertight structure at once using the gravity without using a pump. This is advantageous as an emergency quenching measure.
[0044]
(2) The watertight operation means 32 employs a type in which the support members 41A and 41B and the watertight holding members 42A and 42B come into contact with each other and mechanically interlock with each other. By adopting a type in which members having the same function are electrically synchronized, the same function and effect can be exhibited. The configuration of the watertight operation means is not limited to the support members 41A and 41B and the watertight holding members 42A and 42B, and the first state in which the watertight plate 31 is supported by the article access door 5; Any mechanism may be employed as long as it is a mechanism that can alternatively take the second state in which the cutout portion 26 of the watertight tank 3 is watertightly closed.
[0045]
(3) Although the watertight operation means 32 is operated by manual operation, the watertight operation means 32 is operated based on an electrical signal such as an immersion signal, a rapid cooling signal, or an emergency signal due to high temperature or smoke. It is also possible to automatically perform the watertight operation as described above (so that the watertight holding members 42A and 42B rotate).
[0046]
(4) The operation handle for rotating the watertight holding members 42A and 42B to perform the dipping operation can be shared with the door opening / closing operation handle of the article entry / exit door 5; It is also possible to increase the nature.
[0047]
【The invention's effect】
The present invention is implemented in the form as described above, and has the following effects.
[0048]
In the environmental test apparatus according to the present invention, an opening is formed in a watertight tank disposed in the apparatus housing, and a watertight plate that closes the opening of the watertight tank is supported by the article entrance door by a watertight operation means. Since the first state and the second state in which the opening of the watertight tank is watertightly closed can be taken alternatively, the freedom of taking in and out of the test sample in the watertight tank is possible. It is possible to ensure complete immersion or rapid cooling by filling the watertight tank with water during immersion or rapid cooling.
[0049]
Further, the watertight tank has a side wall and a bottom wall so as to form a double wall inside the apparatus housing, and a moving means for allowing the watertight tank to move on the lower surface of the bottom wall of the watertight tank. If a spare watertight tank is prepared separately, the watertight tank for storing the abnormal product is carried out from the inside of the device housing, and instead of that, the spare watertight tank is carried into the device housing. As a test apparatus, it is possible to perform a similar test on another specimen, and it is not necessary to leave the apparatus idle.
[0050]
The watertight operation means is provided on the article access door and is provided with a plurality of support members capable of supporting appropriate portions of the right and left side edges or the lower edge of the watertight board, and the support of the watertight board by the support members is released. A support releasing member that is provided on the watertight tank side, and a watertight plate that is supported by the support releasing member and that is released by attracting the watertight tank to the watertight tank side to close the opening, and is capable of maintaining the state. By having the holding member, it is possible to easily switch the state of the watertight plate.
[0051]
The watertight holding member has an inclined surface that is in contact with the left and right side edge portions or the lower edge portion of the watertight plate and moves the watertight plate obliquely upward toward the watertight tank side, and the watertight tank includes the opening. If a stopper for restricting the upward movement of the watertight plate is provided above both sides of the part, the first state and the second state of the watertight plate can be obtained with a simple structure using an inclined surface. Can be easily switched.
[0052]
If the water injection means is a water storage tank provided on the upper side of the device housing, the water in the water storage tank can be dropped into the watertight tank at once without using a pump, and water can be injected as a rapid cooling operation. Is extremely effective.
