Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Fig. 1 is a schematic front view of a sample box for sandy soil saturation detection according to an embodiment of the present invention. Fig. 2 is a schematic diagram of a side view of a sample box for sand saturation detection according to an embodiment of the present invention. Fig. 3 is a cross-sectional view of the sample chamber of fig. 2 taken along line a-a.
Referring to fig. 1-3, the sample box for sand saturation detection of the present invention may include a box body 21, a shelf 22 and a filter layer 23.
More specifically, the case 21 has a substantially square case shape, one side of which is open. Other suitable shapes are of course possible, such as a cylinder. A transparent observation window 211 extending vertically is formed in a side wall of the case, and such a transparent observation window 211 may be formed in one side wall or a plurality of side walls. A plurality of protruding fixing members 212 are formed at the periphery of the bottom plate outside the case 21, and the fixing members 212 are used to fix the case 21 to other devices. For example, the fixing member 212 may be formed with a hole (see fig. 4) with which the case 21 can be fixed.
According to an embodiment of the present invention, the transparent observation window 211 may be formed of glass, such as organic transparent glass, and have a scale formed thereon. The accuracy of the scale can be set to, for example, millimeter, tenth millimeter, etc. as required, and the change in the height of the solution inside the tank 21 can be reflected by the scale, thereby reflecting the change in the volume thereof.
In addition, the box body 21 further includes a plurality of hanging rings 216 formed on a top side wall thereof for facilitating movement of the box body, and the box body may be hung and installed by the hanging rings 216, for example.
As shown in the drawings, a support 213 is formed at the periphery and the middle of the inner bottom plate of the case 21 for supporting the shelf 22. That is, the shelf 22 is placed and substantially fixed on the support 213, thereby constituting a cabinet bottom space 214 together with the bottom and side walls of the cabinet 21 and the support 213. The support 213 may be formed continuously, for example as a ring of supports along the periphery of the tank 21, for example as a continuous strip of supports across the bottom, connected to the ring of supports. Of course, it may be in the form of a plurality of support points formed discontinuously as long as the shelf 22 can be fixedly supported. A plurality of through holes 215 are formed on the side wall of the bottom of the box body 21, and the through holes are communicated with a box body bottom space 214; so that a gas such as carbon dioxide, a liquid such as water, etc. can be introduced into the tank through the through-hole 215. The presence of the bottom space 214 allows for the convenient introduction of liquid or gas without clogging.
Fig. 4 is a schematic top view of a sample box for sand saturation detection according to an embodiment of the present invention, wherein the filter layer is not shown. As shown, the shelf 22 is formed with a plurality of openings 221. So that the introduction of gas and liquid, etc. through the through-hole 215 and the bottom space 214 can further penetrate into the tank.
The shelf 22 may be formed in a flat plate type, and the shelf 22 has a shape and size substantially corresponding to a cross-section of the case such that the shelf 22 can be placed and substantially fixed in the case. The filter layer 23 is placed and fixed on the shelf 22, for example, the filter layer 23 substantially conforms to the shape of the shelf 22. The shelf 22 may also be formed to include a recessed portion and a peripheral flange portion, i.e., formed as a flanged basin. An opening 221 is formed in the recess (i.e. the bottom of the tub) and the surrounding flange portion is supported above the support member 213. The shelf 22 may be designed to include a plurality of such basins. As shown in figure 4, two such basins are shown, formed as a flange in the middle, resting on a support 213 formed in the central part of the bottom of the corresponding tank. The respective openings 221 are formed in the bottom of the tub. Such a design allows a better fixation of the filter layer 23.
The filter layer 23 is disposed on the shelf 22, and a soil sample is placed on the filter layer 23. The provision of said filter layer 23 makes it possible to prevent soil from penetrating to the bottom of the tank, adversely affecting the detection of saturation, while allowing liquids, such as water, and gases, such as carbon dioxide, to pass freely. The filter layer 23 may be a sintered copper filter plate, a sintered steel filter plate, a microporous ceramic filter plate, or the like. For example, the sintered copper filter material can be formed by sintering copper alloy powder at a high temperature, and has the characteristics of high filter precision, good air permeability, high mechanical strength, high material utilization rate and the like. Porous elements of various shapes, structures, different particle sizes, porosities can be produced as desired, such as: a hood, cap, sheet, plate, tube, rod-shaped filter element.
When utilizing the utility model discloses a sample box detects, can with filter layer 23 sets up on shelf 22, then with the soil sample dress on shelf 22. The sample box with the sample is placed in another container such as an outer cylinder device and fixed by a fixing member 212. A liquid such as water and a gas such as carbon dioxide, etc. may then be introduced into the sample chamber through the through hole 215, thereby saturating the sample with moisture. While the observation can be made with the transparent observation window 211. And further the saturation of the sample is detected.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
