Description

Technical Field

[0001] The utility model belongs to the technical field of measuring density and volume of objects, and particularly relates to a density and volume measuring device for irregular solids based on liquid level height. Background Art

[0002] In real life and production, the objects we come into contact with inevitably have irregular shapes. More precisely, compared with the ideal regular shapes, the objects involved in real life and production are more irregular in shape. For example, due to the processing technology of the objects, there is inevitably a certain error between the finished product and the ideal design shape, or irregular factors caused by avoidance and other reasons. In addition, in addition to the function of the objects, people often have visual needs, which also makes the outline of the objects show a trend of irregularity.

[0003] Volume and density are both basic properties of objects. For some items (such as commodities), the outer packaging at the sales stage usually contains information such as weight, maximum outline dimensions (such as length, width, and height that roughly correspond to the dimensions of the outer packaging), etc. However, such information often remains at the level of transportation and handling experience, and does not accurately characterize the volume and density properties of the item. In theory, for a given item, if the user needs to quantify these two properties, they should be able to obtain them.

[0004] During the learning process, the inventor encountered a question type about measuring the density of solids by the floating and sinking method. Inspired by this processing method, the inventor believes that a reasonable measurement scheme can be given for the volume and density of irregularly shaped objects based on this principle. It should be noted that the irregularly shaped objects mentioned in the utility model should be understood as irregularly shaped, non-absorbent solids. After consulting the relevant materials, the results of the consultation within the scope of the knowledge system mastered and understood by the inventor generally have the shortcomings of complex structures and / or principles. In addition, the measuring equipment adopts a principle different from the aforementioned "floating and sinking method for measuring the density of solids" mentioned by the inventor. For example, the Chinese invention patent with publication number (CN112986048A) discloses a method and device for measuring the volume and density of irregular rock samples. In this document, fixed particles are used to replace liquid to achieve container filling, thereby achieving the measurement of the particle size of the sample to be measured.

[0005] Accordingly, the inventor would like to propose another technical solution to achieve the measurement of irregularly fixed volume and density. Utility Model Content

[0006] In order to solve the above technical problems at least to a certain extent and / or solve at least part of the above technical problems, the utility model patent proposes a density and volume measuring device for irregular solids based on liquid level height.

[0007] In view of this, the utility model provides a density and volume measuring device for irregular solids based on liquid level height, the device comprising: a base having a first mounting position and a second mounting position; a container portion comprising a first container and a second container; at least one distance detecting component; and a float portion, which can be arranged in a floating manner in the liquid in the first container; wherein the first container is arranged in the first mounting position and the first container can contain liquid; wherein the second container can be arranged in a floating manner in the liquid in the first container; wherein the at least one distance detecting component is arranged in the second mounting position, and in the assembled state, the distance detecting component is located above the float portion.

[0008] With such a configuration, it is possible to determine the density and volume of an irregularly shaped object to be measured based on the change in the liquid level through the cooperation of a set of containers, a float portion, and a distance detection component, such as a distance sensor.

[0009] For the above-mentioned density and volume measuring device for irregular solids based on liquid level, in a possible implementation manner, the float part is formed with a reserved space, and the second container is freely accommodated in the reserved space.

[0010] Through such a structure, a relative positional relationship between the float part and the second container is given, such as the reserved space can be located at one side edge or the middle of the float part, and the containing space is a roughly circular open area.

[0011] It should be noted that the free accommodation here should be understood as: on the one hand, the second container is located in the reserved space formed by the float part; on the other hand, the second container can move freely (such as floating slightly) within the liquid level range corresponding to the reserved space without colliding with the float part. When the float and the second container are both in a stable state and there is no contact between them, the density and volume of the irregular solid can be determined based on the detection result of the distance detection component.

[0012] For the above-mentioned density and volume measuring device for irregular solids based on liquid level, in a possible implementation, the float portion is an annular structure, the reserved space is the space in the middle of the annular structure, and the annular structure has an open side along its circumference.

[0013] Through such a configuration, a possible structural form of the float part is given. Through the setting of the open side, the object to be tested can be put into the liquid of the first container through the open side, such as the open side can be a section of arc-shaped structure opened in the circumferential direction of the annular structure. For example, the float part can be a circular ring structure, a rectangular ring structure, an elliptical ring structure, etc. Exemplarily, the float part is roughly a C-shaped structure with a section of arc-shaped opening on the circular ring structure.

[0014] For the above-mentioned density and volume measuring device for irregular solids based on liquid level height, in a possible implementation, the base includes a second part, wherein a plurality of the second mounting positions are provided on the second part, and each of the second mounting positions can be provided with the distance detecting component; or a track is formed on the second part, and the distance detecting component can slide along the track so as to be located at different positions of the track.

[0015] With such a configuration, it is possible to determine the distance (perpendicular distance in the vertical direction) between the distance detection member and the float portion based on the detection results at the plurality of detection points.

[0016] It is understandable that, for the situation where "a plurality of second mounting positions are provided on the second part", those skilled in the art can determine the structural form of the plurality of second mounting positions and the relative positions between the respective second mounting positions according to actual needs.

[0017] It can be understood that, for the case of "a track is formed on the second part", technical personnel in this field can determine the specific shape of the track, the position where the distance detection component can stay, etc. according to actual needs. For example, the track can be an annular structure consistent with the structure of the aforementioned float part, or it can be an S-shaped structure, U-shaped structure or other structures (but it should have several detection points aligned with the float part), the distance detection component can stay at any position or certain positions of the slide rail, etc.

[0018] For the above-mentioned density and volume measuring device for irregular solids based on liquid level, in a possible implementation manner, the track is a ring-shaped structure.

[0019] Through such a configuration, a possible structural form of the track is given, such as a circular ring structure, a rectangular ring structure, an elliptical ring structure, etc.

[0020] For the above-mentioned density and volume measuring device for irregular solids based on liquid level, in a possible implementation manner, the density of the float part is less than the density of the liquid contained in the first container.

[0021] By such a configuration, the detection reliability of the measuring device can be ensured. For example, in order to ensure the reliability of the measurement, the float part should not absorb water. Under this premise, any reasonable material can be selected as the float part.

[0022] For the above-mentioned density and volume measuring device for irregular solids based on liquid level height, in a possible implementation, the base includes a bracket, the second part is arranged near the upper part of the bracket, the base includes a first part, the first part is arranged near the lower part of the bracket, and the first mounting position is formed on the first part.

[0023] Through such a configuration, a possible structural form of the base is provided, such as the first part is a base, etc., and the first installation position is a recessed part arranged on the base, etc.

[0024] For the above-mentioned density and volume measuring device for irregular solids based on liquid level, in a possible implementation manner, at least a portion of the bracket, the first part and the second part are integrally formed or fixedly connected to each other.

[0025] Through such a configuration, a specific composition mode of the matrix is ​​given. Exemplarily, the three are an integrally formed structure.

[0026] Regarding the above-mentioned density and volume measurement device for irregular solids based on liquid level, in a possible implementation manner, the device is provided with a temperature detection component, and the temperature detection component is capable of detecting the temperature of the liquid contained in the first container.

[0027] With such a configuration, it is possible to more accurately obtain the density of the liquid based on the temperature of the liquid, thereby ensuring the accuracy of the measurement.

[0028] For the above-mentioned density and volume measurement device for irregular solids based on liquid level, in a possible implementation manner, the device is equipped with a mass measurement component, and the mass measurement component is used to measure the mass of the object to be measured.

[0029] By such a configuration, it is possible to achieve dual measurement of density and volume according to the measurement result of the mass measuring component, such as the mass measuring component can be a balance. Obviously, it is also possible to determine the mass of the object to be measured by directly reading the outer packaging information or measuring the mass at other positions different from the density and volume measuring device of the irregular solid based on the liquid level without configuring the mass measuring component.

[0056] In addition, in order to better illustrate the present invention, many specific details are given in the specific embodiments below, and those skilled in the art should understand that the present invention can also be implemented without certain specific details. In some examples, principles well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present invention.

[0057] Example 1

[0058] Main reference Figures 1 to 4 In a possible implementation, the density and volume measuring device 100 for irregular solids based on liquid level mainly includes a base 1, a distance sensor 3, a container part and a float part 6, wherein the container part includes a liquid container 4 and a floating container 5, and the liquid container contains a liquid 200, in this example, the liquid 200 is pure water. The floating container 5 can float the liquid in the liquid container, that is, a part of the floating container is located below the liquid surface, and a part is located above the liquid surface. The distance sensor is located above the floating container.

[0059] In a possible embodiment, the base 1 includes a bracket 10, and a first part 11 and a second part 12 extend horizontally below and above the bracket respectively. The second part has a first mounting position such as a recessed structure. The second part is roughly a circular ring structure, and a track 21 is arranged on the circular ring structure. The distance sensor can slide along the track and stay at multiple second mounting positions in the track.

[0060] In a possible embodiment, the float part 6 is roughly a ring structure with an open side along the circumference, and a reserved space 61 is formed in the middle of the ring structure, so that the floating container 5 can be freely accommodated in the reserved space 61 of the ring structure. Specifically, the inner diameter of the ring structure is larger than the outer diameter of the floating container. For example, the material of the float part should meet the two conditions of being less dense than pure water and not absorbing water, so as to ensure that the floating container 5 can float in the pure water in the liquid container and can accurately determine the density and volume of the object to be measured by distance measurement. The object to be measured can be put into the liquid 200 contained in the liquid container 5 through the open side.

[0061] In a possible implementation, a temperature sensor 7 is provided in the liquid container. Referring to Table 1 below, the density of water varies under different temperature conditions, so based on the detection result of the temperature sensor, the density of water under the current temperature condition can be more accurately obtained by looking up the table.

[0062] Table 1 Correspondence between water density and temperature

[0063]

[0064] In addition, the density and volume measuring device 100 of irregular solids based on liquid level of the present invention can be equipped with a balance 400. For example, based on the density of the object to be measured, the mass of the object to be measured can be measured by the balance, and then the volume of the object to be measured can be calculated.

[0065] It can be seen that in the preferred embodiment of the utility model, the volume and density of an irregularly shaped object to be measured can be determined by a set of containers, a float part and a distance detection component. The structure is simple and easy to operate. Through multi-point detection of the distance detection component, the measurement accuracy of the distance can be improved, thereby improving the measurement accuracy of the density and volume of the object to be measured. In addition, by configuring a temperature detection component, the measurement accuracy of the density and volume of the object to be measured can be further improved under the premise of accurately determining the density of the liquid.

[0066] Example 2

[0067] Main reference Figure 5 and Figure 6 And continue to refer to Figures 1 to 4 In this embodiment, the main difference from the embodiment 1 is the structure of the second part 12. Specifically, in this embodiment, the second part has a plurality of extension ends 22 (three extension ends in this example, and it is obvious that those skilled in the art can select the number of extension ends, the structure of each extension end, and the relative position, etc. according to actual needs), and each extension end 22 has a mounting position (second mounting position), and each mounting position can be provided with a distance sensor 3. Other structures and principles are substantially the same as those in the embodiment, and will not be repeated here.

[0068] The following takes the device of Example 1 as an example, mainly referring to Figure 7 In a possible implementation, the method for measuring the density and volume of an irregularly shaped solid mainly includes the following steps:

[0069] S710, determining a first distance between the distance detection component and the float portion without placing the object to be detected;

[0070] S720, when the object to be detected is placed in the floating container, determining a second distance between the distance detection component and the float part;

[0071] S730, when the object to be detected is directly placed in the liquid container, determining a third distance between the distance detection component and the float portion;

[0072] S740, determining the density of the object to be measured according to the first distance, the second distance and the third distance;

[0073] S750: Determine the density and volume of the object to be measured according to the density of the object to be measured and the obtained mass of the object to be measured.

[0074] In a possible implementation manner, the first distance, the second distance and / or the third distance are determined as follows:

[0075] causing the distance detecting member to detect the distance between the distance detecting member and the upper surface of the float portion at a plurality of detection points;

[0076] The first distance, the second distance and / or the third distance are determined according to the multiple distances.

[0077] Obviously, the first distance, the second distance and the third distance should be measured when the float part is in a stable state.

[0078] Main reference Figure 8 In a specific embodiment, the method for measuring the density and volume of an irregularly shaped solid comprises the following steps:

[0079] S81, before the object to be detected is put into the liquid and the floating container, the first distance between the distance sensor and the float part is detected at multiple detection points by the movement of the distance sensor in the track 2, and on this basis, the average value of the first distances corresponding to the multiple detection points is calculated and the average value is used as the first distance h1 between the distance sensor and the upper surface of the float part;

[0080] S82, after the object to be detected is placed in the floating container, the second distance between the distance sensor and the float part is detected at multiple detection points by the movement of the distance sensor in the track, and on this basis, the average value of the second distances corresponding to the multiple detection points is calculated and the average value is used as the second distance h2 between the distance sensor and the upper surface of the float part;

[0081] S83, after taking out the object to be measured from the floating container and directly putting the object to be measured into the liquid, the third distance between the distance sensor and the float part is detected at multiple detection points by the movement of the distance sensor in the track, and on this basis, the average value of the third distances corresponding to the multiple detection points is calculated, and the average value is used as the third distance h3 between the distance sensor and the upper surface of the float part;

[0082] S84. Calculate the density and volume of the object to be measured according to the first distance h1, the second distance h2 and the third distance h3:

[0083] The density of the object to be measured is calculated by the following formula:

[0084]

[0085] Among them, the volume V of the object to be measured 被测物体 It can be calculated by the following formula:

[0086]

[0087] Among them, the mass m of the object to be measured can be directly measured by a balance. 待测物体 .

[0088] In this embodiment, the liquid is preferably pure water, the density of the object to be measured should be higher than that of water, and the density of the float part should be lower than that of the liquid, such as the material is foam. 液体 It can be found in the above Table 1.

[0089] It should be pointed out that, although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effect of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously or in other orders. Some steps can also be added, replaced or omitted. For example, the order of S710-S830 and S81-S83 can be swapped.

[0090] It should be noted that, although the above specific method is introduced as an example, those skilled in the art will understand that the present invention should not be limited thereto. In fact, the user can flexibly adjust the relevant steps and the parameters in the steps according to the actual application scenario, such as determining the first / second / second distance only by one detection value, or determining the first / second / second distance by other calculation methods besides averaging.

[0091] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
