Description

Technical Field

[0001] The utility model belongs to the technical field of gas content detection of building mortar, and particularly relates to a high-precision gas content detection device for building mortar. Background Art

[0002] In today's construction industry, mortar, as an important building material, is widely used in the construction of various building structures. Its performance is directly related to the overall quality and durability of the building. As a key performance indicator, the air content in mortar has a significant impact on many aspects of the mortar, including strength, impermeability, and frost resistance.

[0003] Traditional methods and devices for measuring mortar air content have exposed a series of problems in practical applications. In the past, common measurement devices were relatively simple in structure and design, with relatively single functions. Many devices relied solely on simple gas injection and measurement methods to estimate air content, lacking effective intervention and treatment methods for the distribution of bubbles within the mortar. Because the complex characteristics of mortar were not fully considered, these devices often failed to achieve the ideal level of measurement accuracy and were unable to accurately reflect the actual air content in the mortar, thus introducing greater uncertainty in material evaluation and quality control in construction.

[0004] At the same time, some devices only use simple stirring methods, which cannot effectively break the agglomerated structure in the mortar, making it difficult for the bubbles to be evenly dispersed, resulting in large deviations in the measurement results.

[0005] Secondly, traditional devices haven't paid sufficient attention to the role of vibration in measuring mortar air content. The lack of an effective vibration mechanism prevents the mortar from fully expelling excess air during measurement, leading to uneven bubble distribution and inaccurate air content measurements. For example, some devices struggle to control stirring speed and intensity during mixing, resulting in localized vortices and dead spots within the mortar, trapping bubbles and preventing their uniform distribution throughout the mortar.

[0006] Due to insufficient stirring and vibration, traditional devices for measuring mortar air content not only struggle to guarantee accuracy but also suffer from poor repeatability and stability. This significantly impacts the evaluation and quality control of mortar performance during construction, and can easily lead to problems such as insufficient structural strength, reduced impermeability, and decreased frost resistance.

[0007] To this end, we have proposed a high-precision device for measuring the air content of construction mortar. Through the synergistic effect of stirring and vibration, the device makes the air bubbles in the mortar more evenly distributed, thereby being able to measure the air content more accurately and reduce measurement errors. Utility Model Content

[0008] The purpose of this utility model is to provide a high-precision measuring device for the air content of building mortar, which makes the air bubbles in the mortar more evenly distributed through the synergistic effect of stirring and vibration, thereby being able to measure the air content more accurately and reduce measurement errors.

[0009] The technical solutions adopted in this application are as follows:

[0010] A high-precision measurement device for the air content of building mortar, comprising a base, two symmetrical slide grooves are provided on the top of the base, an elastic movable component is provided inside each of the slide grooves, an arc-shaped bracket is provided on the top of the elastic movable component, a connecting plate and a first arc-shaped magnetic block are provided on one side of the arc-shaped bracket from top to bottom, a bearing cylinder for bearing mortar is installed at one end of the connecting plate away from the arc-shaped bracket, a sealing cover is provided on the sealing cover, a pressure gauge is provided, and a dual-axis motor is installed at the bottom of the bearing cylinder, a stirring assembly located inside the bearing cylinder is installed at one output end of the dual-axis motor, a rotating disk is installed at the other output end of the dual-axis motor, and a second arc-shaped magnetic block that repels the first arc-shaped magnetic block is provided on the outside of the rotating disk.

[0011] Furthermore, the bearing tube and the sealing cover are connected by bolts.

[0012] Furthermore, the stirring assembly includes a rotating rod connected to the output end of the dual-axis motor, the rotating rod is located inside the carrying cylinder, and a stirring rod is provided on the outside of the rotating rod.

[0013] Furthermore, the elastic moving component includes a fixed shaft arranged inside the sliding groove, a slider and a spring are sleeved on the fixed shaft, the springs are arranged on both sides of the slider, and the top of the slider is connected to the arc-shaped bracket.

[0014] Furthermore, the sliding block matches the sliding groove.

[0015] Furthermore, a reduction motor is provided on the dual-axis motor.

[0016] The technical effects achieved by this utility model are:

[0017] First, mortar is placed inside the carrier tube, which is then sealed with a sealing cover. The dual-axis motor is then started, and one output end of the dual-axis motor drives the stirring assembly to stir the mortar inside the carrier tube, making the gas content evenly distributed. Simultaneously, the other output end of the dual-axis motor drives the rotating disk to rotate. When the rotating disk rotates to one arc-shaped bracket, the first arc-shaped magnetic block aligns with the second arc-shaped magnetic block, generating a repulsive force. This, through the action of the elastic moving assembly, causes the entire carrier tube to move and vibrate. When the rotating disk rotates to the other arc-shaped bracket, the first arc-shaped magnetic block on it aligns with the second arc-shaped magnetic block, generating a repulsive force, causing the entire carrier tube to move and vibrate. This reciprocating process causes the carrier tube to vibrate. This vibration and rotation help to more evenly distribute the bubbles in the mortar and improve the accuracy of gas content measurement. By observing the reading on the pressure gauge, the gas content of the mortar can be accurately measured. The device achieves a more even distribution of bubbles in the mortar through the synergistic effect of stirring and vibration, enabling more accurate gas content measurement and reducing measurement errors.

[0024] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0025] like Figure 1-4As shown, the technical solution adopted by the present invention is as follows: a high-precision measuring device for the air content of building mortar, comprising a base 1, two symmetrical chutes 2 are provided on the top of the base 1, an elastic moving component is provided inside each chute 2, an arc-shaped bracket 3 is provided on the top of the elastic moving component, a connecting plate 4 and a first arc-shaped magnetic block 5 are provided on one side of the arc-shaped bracket 3 from top to bottom, a supporting tube 6 for supporting the mortar is installed at the end of the connecting plate 4 away from the arc-shaped bracket 3, a sealing cover 7 is provided on the top of the supporting tube 6, a pressure gauge 8 is provided on the sealing cover 7, the model of the pressure gauge is a Y-40 direct pressure gauge, and a dual-axis motor 9 is installed at the bottom of the supporting tube 6, a stirring component located inside the supporting tube 6 is installed at one output end of the dual-axis motor 9, a rotating disk 10 is installed at the other output end of the dual-axis motor 9, and a second arc-shaped magnetic block 11 that repels the first arc-shaped magnetic block 5 is provided on the outside of the rotating disk 10.

[0026] The supporting tube 6 and the sealing cover 7 are connected by bolts 12 , which ensures the sealing of the container during the measurement process and prevents gas leakage.

[0027] At the same time, the supporting tube 6, the sealing cover 7 and the pressure gauge 8 constitute a mortar air content measuring instrument in the prior art.

[0028] The structure of the mortar air content tester is:

[0029] 1. Container: used to hold the mortar to be measured.

[0030] 2. Sealing device: ensure the sealing of the container during the measurement process to prevent gas leakage.

[0031] 3. Pressure measuring component: usually a pressure gauge 8 or a pressure sensor, used to measure the pressure changes in the container.

[0032] 4. Inlet and exhaust valves: used to control the inlet and outlet of gas.

[0033] Working principle:

[0034] First, pour the well-mixed mortar into the measuring instrument's container and install a seal. Next, a predetermined amount of gas is introduced into the container through the inlet valve. Once the specified pressure is reached, the inlet valve is closed. The air content in the mortar is calculated based on the pressure change and known parameters such as the container volume. Alternatively, the air content can be indirectly determined by measuring the volume of the exhausted gas. Finally, the pressure measurement component displays or calculates the air content of the mortar.

[0035] The mortar air content measuring instrument belongs to the existing technology and will not be described in detail here.

[0036] The stirring assembly includes a rotating rod 13 connected to the output end of the dual-axis motor 9. The rotating rod 13 is located inside the supporting cylinder 6, and a stirring rod 14 is provided on the outside of the rotating rod 13. When the dual-axis motor 9 rotates, it drives the rotating rod 13 to rotate. The rotating rod 13 drives the stirring rod 14 to stir the mortar inside the supporting cylinder 6, so that the air content is evenly distributed.

[0037] In order to prevent the rotating disk 10 from rotating too fast and causing the bearing cylinder 6 to vibrate too much, a reduction motor (not shown in the figure) can be provided on the dual-axis motor 9 to reduce the rotation speed of the reduction motor.

[0038] It should be noted that the connection method between the dual-axis motor and the reduction motor has been disclosed in the prior art and will not be described in detail here.

[0039] The elastic moving component includes a fixed shaft 15 arranged inside the slide groove 2, a slider 16 and a spring 17 are sleeved on the fixed shaft 15, springs 17 are provided on both sides of the slider 16, and the top of the slider 16 is connected to the arc bracket 3.

[0040] When the arc-shaped bracket 3 moves, the slider 16 is driven to move on the fixed shaft 15 and squeeze the spring 17. The elastic force of the spring 17 causes the load-bearing member to vibrate, thereby performing work.

[0041] The slider 16 matches the chute 2 , and matching here means that the slider 16 can move smoothly inside the chute 2 without getting stuck.

[0042] The dual-shaft motor 9 is a motor with two output shafts. There are many types of dual-shaft motors, and the most common ones are a DC dual-shaft motor 9 and an AC dual-shaft motor 9 .

[0043] structure:

[0044] The dual-axis motor 9 primarily consists of a stator, rotor, front and rear end covers, bearings, brushes (for DC motors), and windings. The stator, which contains an iron core and windings, provides a magnetic field; the rotor, typically composed of an iron core and conductors, rotates within the magnetic field. The two output shafts of the dual-axis motor 9 extend from each end of the motor.

[0045] Working principle:

[0046] 1. DC dual-axis motor 9: The stator generates a fixed magnetic field, which supplies power to the rotor winding through brushes and a commutator, causing the current direction in the rotor winding to continuously change, thereby generating torque under the action of the stator magnetic field, driving the two output shafts to rotate.

[0047] 2. AC dual-axis motor 9: divided into asynchronous motor and synchronous motor.

[0048] Asynchronous motor: Alternating current is passed through the stator winding to generate a rotating magnetic field, and an induced current is generated in the rotor winding. The induced current interacts with the rotating magnetic field to generate electromagnetic torque, driving the rotor to rotate, thereby driving the two output shafts to rotate.

[0049] Synchronous motor: The stator winding generates a rotating magnetic field. The magnetic poles on the rotor interact with the stator rotating magnetic field, causing the rotor to rotate at the same speed as the stator magnetic field, achieving synchronous rotation of the two output shafts.

[0050] The dual-axis motor 9 belongs to the prior art and will not be described in detail here.

[0051] The working principle of the utility model is as follows: first, the mortar is placed inside the supporting tube 6, and then the inside of the supporting tube 6 is sealed by the sealing cover 7, and then the dual-axis motor 9 is started, and one output end of the dual-axis motor 9 drives the stirring assembly to stir the mortar inside the supporting tube 6 to make the gas content evenly distributed. At the same time, the other output end of the dual-axis motor 9 drives the rotating disk 10 to rotate. When the rotating disk rotates to an arc-shaped bracket 3, the first arc-shaped magnetic block 5 corresponds to the position of the second arc-shaped magnetic block 11, thereby generating a repulsive force. Therefore, through the action of the elastic moving component, the entire supporting tube 6 moves to generate vibration. When rotating to another arc-shaped bracket 3, the first arc-shaped magnetic block 5 and the second arc-shaped magnetic block 11 thereon correspond to the position, thereby generating a repulsive force. The entire supporting tube 6 moves to generate vibration, and reciprocates in sequence, and the supporting tube 6 generates vibration. This vibration and rotation help to distribute the bubbles in the mortar more evenly and improve the measurement accuracy of the gas content. By observing the reading on the pressure gauge 8, the gas content of the mortar can be accurately measured. The device makes the bubbles in the mortar more evenly distributed through the synergistic effect of stirring and vibration, thereby being able to measure the gas content more accurately and reduce measurement errors.

[0052] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
