Description

Technical Field

[0001] This invention relates to the field of thermal insulation material testing technology, and in particular to an intelligent testing device for the density of thermal insulation materials. Background Technology

[0002] Organic thermal insulation materials, as a core component of building envelope energy-saving systems, play a crucial role in achieving near-zero energy building goals through performance optimization. These polymer-based insulation systems not only need to meet increasingly stringent thermal performance specifications but also require the coordination of knowledge from multiple disciplines, including materials science and heat transfer, to achieve a balance between lightweighting, resource conservation, and engineering applicability. Density, a core parameter throughout the entire process of material research, development, production, and application, directly determines insulation performance, structural safety, and service life; its precise control becomes an economic lever for balancing performance and cost. Any irrational adjustment to density can trigger a chain reaction of problems, such as decreased insulation performance, increased safety hazards, or shortened project lifespan. Therefore, density testing and monitoring from the laboratory to the engineering site are the cornerstones for ensuring material quality standards are met.

[0003] However, current density testing of thermal insulation materials generally relies on traditional manual operation methods, involving manual measurement of sample three-dimensional dimensions, repeated weighing, and tedious calculations. This method involves a large amount of repetitive work, lengthy operation steps, significantly extended testing cycles, and is easily affected by operator experience and environmental factors, resulting in high data volatility and insufficient reliability.

[0029] Traditional methods for testing the density of thermal insulation materials largely rely on manual operation, resulting in repetitive workloads and lengthy testing times. Improving testing efficiency while ensuring measurement accuracy has become a key focus in the industry. Current technologies still face challenges in achieving efficient and accurate measurement of thermal insulation material density, failing to meet the growing demands of building energy efficiency standards for rapid material performance evaluation.

[0030] Please refer to the following for details. Figures 1 to 3 This application proposes an intelligent testing device for the density of thermal insulation materials. The device consists of a main body 1, a weighing platform 2, a testing frame 3, and a telescopic measuring device 4. The top surface 31, right side 34, and front surface 35 of the testing frame 3 are movable, and the telescopic measuring device 4 measures these displacements, thereby realizing the automated measurement of the weight and volume of the thermal insulation material and calculating its density, effectively improving testing efficiency and accuracy.

[0031] The main body 1 can be a box structure, for example, formed by welding or bolting together metal sheets. The box can integrate electronic components such as power modules and data processing units. The main body 1 is designed to provide a stable foundation to support the weight of all components above and resist vibrations that may occur from the external environment, thus ensuring the accuracy of the measurement process. The weighing platform 2 is located on top of the main body 1; it can be a flat support plate with multiple weighing sensors integrated underneath. For example, resistance strain gauge sensors can be used, evenly distributed at the bottom of the weighing platform 2, to detect the deformation and obtain the weight of the insulation material placed on the weighing platform 2. The surface of the weighing platform 2 can be made of a wear-resistant and easy-to-clean material to ensure the stability of the insulation material.

[0032] The test frame 3 is mounted on the weighing platform 2, with its bottom surface 32 in close contact with the platform 2, for placing the insulation material to be tested. The top surface 31, right side 34, and front surface 35 of the test frame 3 are designed to be movable. The top surface 31, right side 34, and front surface 35 can be moved manually or driven by an external mechanism. For example, the top surface 31 can be raised and lowered using a pair of externally arranged vertical guide rails and a drive motor to accommodate insulation materials of different heights. The right side 34 and front surface 35 can be moved laterally using externally arranged horizontal guide rails and a drive motor, thereby adjusting the internal dimensions of the test frame 3 to accommodate insulation materials of different widths and lengths. The left side 33, back side 36, and bottom surface 32 can be designed as fixed structures, serving as reference surfaces for measurement.

[0033] The telescopic measuring device 4 is disposed outside the test frame 3 to measure the displacement of the top surface 31, right surface 34, and front surface 35. For example, non-contact sensors, such as laser displacement sensors or ultrasonic sensors, can be used. These sensors can be fixed to a bracket outside the test frame 3, with their measuring beam or sound wave aligned with the movable top surface 31, right surface 34, or front surface 35. As these surfaces move, the sensors can detect changes in the distance between themselves and the surface in real time, thereby obtaining accurate displacement data. These sensors can operate independently, measuring the displacement of their respective surfaces separately.

[0034] This device provides stable support through the main body 1, and the weighing platform 2 accurately obtains the weight of the insulation material. The movable top surface 31, right side 34, and front surface 35 of the test frame 3, combined with the external telescopic measuring device 4 for precise measurement of displacement, enable automated determination of the insulation material volume. Therefore, the device can automatically calculate and output the density data of the insulation material, effectively solving the problems of repetitive work and time-consuming processes in traditional manual testing methods. This significantly improves the efficiency and accuracy of insulation material density testing, meeting the needs of the building energy conservation field for rapid material performance evaluation.

[0035] This application further proposes a test frame 3 comprising a plurality of connected fasteners and telescopic members, the telescopic members being adapted to move relative to the fasteners such that the top surface 31 is adapted to approach or move away from the bottom surface 32, the right surface 34 is adapted to approach or move away from the left surface 33, and the front surface 35 is adapted to approach or move away from the back surface 36.

[0036] Specifically, the fasteners are the basic structure of the test frame 3, and their function is to provide stable support and positioning, ensuring that the test frame 3 remains rigid and undeformed during measurement. The fasteners can be made of high-strength metal materials (such as aluminum alloys and stainless steel) through welding, bolting, or integral molding processes to form a robust skeleton. For example, they can include vertical columns and horizontal beams, which are interconnected to form the stable periphery of the test frame 3.

[0037] The telescopic component is a key part for realizing the variable internal space of the test frame 3. It is defined as a mechanism capable of changing its own length or position to achieve relative movement with other components. The telescopic component can be implemented in various forms; for example, it can be a linear motion unit consisting of a linear guide rail and a sliding rod, where the sliding rod moves precisely on the guide rail via a drive device (such as a stepper motor or servo motor in conjunction with a lead screw, rack and pinion, or synchronous belt).

[0038] The telescopic component can move precisely and controllably relative to the fixed component, allowing the top surface 31, right side 34, and front surface 35 of the test frame 3 to move flexibly closer to or further away from their opposite surfaces. This enables the test frame 3 to efficiently and accurately adapt to insulation materials of different sizes and shapes. Whether adjusting the height to accommodate materials of different thicknesses or adjusting the width and depth to accommodate materials of different cross-sections, this can be achieved through the precise displacement of the telescopic component.

[0039] like Figure 1 and Figure 2 As shown, this application further proposes that the main body 1 is provided with a first display screen 11 and a control and analysis mechanism, and the telescopic measuring device 4 is electrically connected to the first display screen 11 and the control and analysis mechanism.

[0040] Specifically, the main body 1 can be an integrated device housing or console to house and protect the internal electronic components and provide an operating interface. The first display screen 11 is an electronic display device for real-time display of measurement data, such as an LCD screen, an OLED screen, or a touch screen, which can intuitively present the displacement, calculated density value, and other relevant parameters. The control and analysis mechanism is the core processing unit of the device, responsible for receiving, processing, and analyzing data from the telescopic measuring device 4 and performing tasks such as density calculation. Data transmission and communication between the telescopic measuring device 4, the first display screen 11, and the control and analysis mechanism are achieved through electrical connections.

[0041] Through the above technical solution, the displacement data collected in real time by the telescopic measuring device 4 can be rapidly transmitted to the control and analysis mechanism for automated processing via electrical connection. For example, combined with the mass data provided by the weighing platform 2, the density of the insulation material can be accurately calculated. Simultaneously, the first display screen 11 can instantly and intuitively display these measurement results and analysis data, greatly improving operational convenience and testing efficiency. Users do not need to manually record and calculate, reducing human error and ensuring data accuracy, thus making the density testing process of the insulation material more intelligent, efficient, and precise.

[0042] like Figure 4 As shown, this application further proposes that the test frame 3 is provided with at least one second display screen 37, which is used to display displacement data of the top surface 31, right surface 34, or front surface 35. The second display screen 37 can be an electronic display device capable of receiving and presenting data information. Specifically, the second display screen 37 can directly display the displacement values ​​in each direction (top surface 31, right surface 34, front surface 35) in digital form, and obtain data such as the length, width, and height of the insulation material.

[0043] This application further proposes that the intelligent testing device for the density of thermal insulation materials includes three expansion and contraction measuring devices 4, one expansion and contraction measuring device 4 is set on the top surface 31, one expansion and contraction measuring device 4 is set on the right side 34, and one expansion and contraction measuring device 4 is set on the front side 35.

[0044] Specifically, the telescopic measuring device 4 is a device used to accurately measure the displacement of an object. It can be implemented using a contact-type linear displacement sensor, such as a potentiometer or magnetostrictive sensor, which senses and outputs a displacement signal through mechanical contact. These telescopic measuring devices 4 can all convert physical displacement into processable electrical or digital signals.

[0045] A telescopic measuring device 4 is positioned corresponding to the top surface 31, designed to accurately capture the displacement changes of the top surface 31 of the test frame 3 in the vertical direction. For example, the telescopic measuring device 4 can be installed above the test frame 3 with its measuring end pointing towards the top surface 31, continuously monitoring the distance change of the top surface 31 relative to the bottom surface 32 in a non-contact or slight-contact manner.

[0046] A telescopic measuring device 4 is positioned corresponding to the right side 34, designed to accurately capture the horizontal displacement changes of the right side 34 of the test frame 3. For example, the telescopic measuring device 4 can be installed outside the test frame 3 with its measuring end pointing towards the right side 34, continuously monitoring the distance change of the right side 34 relative to the left side 33 in a non-contact or slight-contact manner.

[0047] A telescopic measuring device 4 is positioned corresponding to the front 35 and is designed to accurately capture the displacement changes of the front 35 of the test frame 3 in the depth direction. For example, the telescopic measuring device 4 can be mounted on the outside of the test frame 3 with its measuring end pointing towards the front 35, continuously monitoring the distance change of the front 35 relative to the back 36 in a non-contact or slight-contact manner.

[0048] Through the above technical solution, the intelligent testing device for thermal insulation material density is equipped with three independent telescopic measuring devices 4, specifically designed to measure the displacement of the top surface 31, right side 34, and front surface 35 of the test frame 3. This allows for the step-by-step acquisition of displacement data in three orthogonal directions, thus avoiding the cumbersome process of multiple adjustments required in traditional methods and significantly improving testing efficiency. Furthermore, each telescopic measuring device 4 focuses on displacement measurement in a specific direction, enabling more precise capture of minute deformations in that direction.

[0049] Please refer to the reference. Figure 1 and Figure 5This application further proposes a telescopic measuring device 4 including a body 41 and a telescopic measuring element 42. One end of the telescopic measuring element 42 is connected to the body 41, and the other end is connected to the top surface 31, the right surface 34, or the front surface 35. The body 41 is adapted to drive the telescopic measuring element 42 to telescopically extend or retract relative to the body 41, so that no interaction force is generated between the telescopic measuring element 42 and the top surface 31, the right surface 34, and the front surface 35.

[0050] Specifically, the body 41 refers to the fixed part or base of the telescopic measuring device 4, which provides stable support and a driving platform for the telescopic measuring component 42. The body 41 can be a bracket fixed to the main body 1, or it can be a cavity integrated into the external structure of the test frame 3. Its function is to provide a stable reference point and power source, ensuring that the telescopic measuring component 42 can accurately perform telescopic movements and avoiding errors introduced during measurement due to its own instability. The telescopic measuring component 42 refers to the telescopic part of the telescopic measuring device 4 that directly contacts the top surface 31, right side 34, or front surface 35 of the test frame 3 and performs displacement measurement. The telescopic measuring component 42 can take various forms; for example, it can be a push rod with a displacement sensor, driven by an internal spring or motor for telescopic movement.

[0051] The body 41 is adapted to drive the telescopic measuring element 42 to extend and retract relative to the body 41. That is, the body 41 integrates a drive mechanism inside or outside, which can actively control the movement of the telescopic measuring element 42. The drive mechanism can take various forms. For example, it can be a micro stepper motor combined with a lead screw transmission mechanism, which drives the linear extension and retraction of the telescopic measuring element 42 by precisely controlling the rotation of the motor; it can also be a pneumatic or hydraulic drive system, which pushes the telescopic measuring element 42 to extend and retract by controlling air pressure or hydraulic pressure.

[0052] Through the above technical solution, the body 41 of the telescopic measuring device 4 serves as a stable support and driving platform, enabling precise control of the movement of the telescopic measuring component 42. After the telescopic measuring component 42 is connected to the top surface 31, right side 34, or front surface 35 of the test frame 3, the body 41 can actively drive the telescopic measuring component 42 to extend or retract. During this process, a precise control mechanism ensures that no significant interaction force is generated between the telescopic measuring component 42 and the corresponding surface of the test frame 3 when measuring displacement. This zero-force measurement method effectively avoids the problem that traditional measuring devices may apply additional pressure to the test frame 3, leading to deformation of the insulation material, displacement distortion, or inaccurate measurement results. Especially when measuring soft and easily deformable insulation materials, this solution can minimize the interference of the measurement process on the physical state of the material, ensuring that the measured displacement data truly reflects the actual size of the insulation material. By combining the above-mentioned three telescopic measuring devices 4 respectively corresponding to the top surface 31, right surface 34 and front surface 35, this application can simultaneously perform high-precision and interference-free displacement measurement of the length, width and height of the insulation material, thereby providing more accurate and reliable raw data for subsequent density calculation, and significantly improving the overall measurement accuracy and reliability of the intelligent testing device for insulation material density.

[0053] This application further proposes a telescopic measuring device 4 including a plurality of telescopic measuring elements 42, which are spaced apart on the side of the body 41 facing the test frame 3.

[0054] Specifically, the telescopic measuring element 42 is the core component of the telescopic measuring device 4, used to directly contact the surface being measured and sense its displacement. It typically includes a telescopic rod-like or columnar structure with an integrated displacement sensor that converts mechanical displacement into an electrical signal. The telescopic measuring device 4 no longer relies on a single telescopic measuring element 42 for displacement measurement; instead, it uses multiple telescopic measuring elements 42. These telescopic measuring elements 42 are spaced apart on the side of the body 41 facing the test frame 3, enabling synchronous or quasi-synchronous displacement measurement of multiple points on the insulation material, significantly improving the comprehensiveness and accuracy of the displacement measurement. When the surface of the insulation material may be uneven, locally deformed, or large in size, a single measuring point is prone to local errors or may not effectively cover the entire measuring surface, leading to deviations in the overall density calculation. The spaced arrangement of multiple telescopic measuring elements 42 ensures that the measuring points are evenly distributed on the corresponding surface of the test frame 3, enabling a more comprehensive capture of the actual dimensional changes of the insulation material and effectively avoiding a decrease in overall accuracy due to local measurement errors. Understandably, measurement errors can be reduced by calculating the average data of multiple telescopic measuring elements 42 on the same telescopic measuring device 4.

[0055] This application further proposes that multiple telescopic measuring elements 42 be arranged in two rows on the body 41. For example, these telescopic measuring elements 42 can be evenly distributed in two parallel straight lines along the length or width direction of the body 41, thereby ensuring that measurement points are covered in both main dimensions of the measurement area, providing more comprehensive displacement data. Alternatively, the telescopic measuring elements 42 can be arranged in two staggered (e.g., zigzag or quincunx) arrangements, such that the first row of telescopic measuring elements 42 is offset from the second row of telescopic measuring elements 42 by a certain distance along the axial direction of the body 41. This staggered arrangement can further improve the density and uniformity of measurement points, effectively reducing measurement blind spots.

[0056] This application further proposes that the number of multiple telescopic measuring elements 42 be three in the first column and four in the second column. For example, when measuring a surface that may have non-uniform deformation in the width or length direction, the asymmetrical arrangement of three and four telescopic measuring elements 42 can make the measurement points more densely distributed or more representative in the key areas, thereby capturing displacement information more comprehensively.

[0057] This application further proposes that the multiple telescopic measuring elements in the second column are all located in the second plane, and the orthographic projection of the telescopic measuring elements in the first column onto the second plane is located between two adjacent telescopic measuring elements in the second column.

[0058] By setting the number of multiple telescopic measuring elements 42 to three in the first column and four in the second column, this asymmetrical 3-4 configuration can optimize the distribution of measuring points on the measured surface according to the actual size and deformation characteristics of the test frame 3. This ensures that the displacement is collected more evenly and comprehensively throughout the entire measurement area, avoiding blind spots or excessive concentration in local areas, thereby significantly improving the accuracy and stability of displacement measurement.

[0059] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
