Referring to fig. 1-3, fig. 1-3 show a front view, a top view, and a left side view of a portable concrete electric flux detector according to an embodiment of the present application. As can be seen from the attached drawings 1-3, the embodiment of the utility model provides a portable concrete electric flux detector includes automobile body 1 and detector body 2. The vehicle body 1 is a support carrier of the portable concrete electric flux detector provided by the embodiment of the application, and is mainly used for supporting and carrying the detector body 2, so that the detector body 2 is arranged on the vehicle body 1. The detector body 2 is a detection part of the portable concrete electric flux detector provided by the embodiment of the application and is used for detecting a concrete sample.
Specifically, the vehicle body 1 includes a floor 8, a stationary backplate 9, a tie rod 10, and the like.

Since the test site may be changed as needed and the test environments are different, the portable concrete electric flux tester needs to be carried or moved frequently. In order to facilitate carrying and placing a portable concrete electric flux detector everywhere, wheels 3 are arranged at the bottom of the vehicle body 1. Specifically, the wheels 3 are arranged at the joint of the fixed back plate 9 and the bottom plate 8, so that the portable concrete electric flux detector is convenient to move. When the portable concrete electric flux measuring apparatus is moved to a measuring place, the vehicle body 1 needs to be fixed in order to prevent the detection accuracy from being affected by the rolling of the wheels 3. Therefore, in the embodiment of the present application, the surface of the bottom plate 8 facing away from the monitor body 2 is provided with the support column 12, that is, the side of the bottom plate 8 facing the ground is provided with the support column 12. Meanwhile, the support column 12 is arranged on one side of the bottom plate 8 far away from the wheel 3, at the moment, the wheel 3 and the support column 12 form a stable supporting relation, and further the balance effect of the supporting vehicle body 1 can be achieved.
Further, because the height of a user of the portable concrete electric flux detector is not fixed, a pull rod 10 is arranged at the top of the fixed back plate 9 so as to facilitate the movement of the user with different heights to the portable concrete electric flux detector. The pull rod 10 can be extended and retracted into the inside of the stationary backplate 9 to reduce the space occupation. The top of the pull rod 10 is also fixedly provided with a handle 11 so as to facilitate the pushing and pulling of a user.
The tester body 2 has a rectangular structure, and an integrated circuit (not shown) is disposed inside the tester body. The integrated circuit is used to control the movement of the components in the test assembly 7 and the testing of the concrete sample. The outer side wall of the detector body 2 is provided with a control panel 4, and the control panel 4 is electrically connected with the integrated circuit. When the user uses the control panel 4, since the control panel 4 is electrically connected to the integrated circuit, the movement of the detecting member 7 and the detection of the concrete sample can be controlled by the integrated circuit. Further, in order to display the detection result of the concrete sample, a display screen 13 is further arranged on the outer side wall of the detector body 2, and the display screen 13 is electrically connected with the integrated circuit. In order to facilitate the arrangement of the control panel 4, the detection table 5 and the display 13, the control panel 4 is located on the same outer side wall of the detector body 2. Furthermore, in order to prevent the display screen 13 from being damaged due to improper operation of a user or other external force factors, a layer of organic glass can be arranged outside the display screen 13, so as to protect the display screen 13.
In this application embodiment, still all be equipped with on the relative both sides wall outer wall of detector body 2 and examine test table 5 and cable through hole 6, the both sides of detector body 2 symmetry all are provided with respectively promptly and examine test table 5 and cable through hole 6. In addition, two opposite detection tables 5 are respectively positioned at two sides of the control panel 4, so that the detector body 2 is in a symmetrical structure. The detection platform 5 is a component for placing and detecting a concrete sample, and the cable through hole 6 is a component for connecting the test cable 701 with the integrated circuit and a detection electrode on the detection platform 5.
Specifically, detect fixed being provided with multiunit determine module 7 on the platform 5, every group determine module 7 can realize the clamp of a concrete sample and detect, therefore detect platform 5 in this application embodiment can realize the clamp of multiunit concrete sample and detect simultaneously. The number of the sets of the detecting assemblies 7 is not particularly limited in the embodiments of the present application, and the structure of the detecting table 5 described in the portable concrete electric flux detector provided in the embodiments of the present application is within the protection scope of the present application.
Referring to fig. 4, fig. 4 shows a schematic structural diagram of a set of detecting elements 7. As shown in fig. 4, each set of detecting elements 7 has a symmetrical structure, and includes a testing cable 701, a threaded rod 707, and a moving plate 702, a clamping table 703 and a fixing block 706, all of which are symmetrically disposed. Specifically, the fixing block 706 is fixedly disposed on the inspection table 5 and is a supporting member of the inspection unit 7. A threaded rod 707 is provided between the two fixed blocks 706 disposed opposite to each other, and both ends of the threaded rod 707 are respectively provided on the two fixed blocks 706 disposed opposite to each other via bearings 708, whereby the threaded rod 707 can rotate between the two bearings 708. The fixed block 706 is provided with a driving motor 714 inside, and an output shaft of the driving motor 714 is connected with an end of the threaded rod 707, so that when the driving motor 714 rotates, the threaded rod 707 can be driven to rotate between the two bearings 708. Further, to facilitate control of the activation and deactivation of the drive motor 714, the drive motor 714 is also electrically connected to the control panel 4.
A connecting snap ring 709 is fixedly arranged on the threaded rod 707, and the threaded rod 707 is also in threaded connection with the two moving plates 702. Specifically, a connecting snap ring 709 is fixedly arranged in the middle of the threaded rod 707. Threaded rod 707 penetrates through two moving plates 702, and at the contact position of threaded rod 707 and moving plates 702, moving plates 702 are provided with threads which are matched with the threads on threaded rod 707. Thus, drive motor 714 rotatably drives threaded rod 707 between bearings 708, which causes two moving plates 702 to be driven on threaded rod 707. To clamp the concrete sample, the two moving plates 702 should be moved toward each other so that the threads of the threaded rod 707 on both sides of the connecting snap ring 709 are opposite. Since the two moving plates 702 are respectively located at both sides of the connection snap ring 709, the screw threads on the two moving plates 702 are opposite in direction. At this time, when the driving motor 714 in one of the fixed blocks 706 rotates, the threaded rod 707 is driven to rotate, and the two moving plates 702 are driven to move towards each other, so as to finally clamp the concrete sample. When the driving motor 714 rotates reversely, the threaded rod 707 is driven to rotate reversely, and then the two moving plates 702 are driven to move reversely, and finally the concrete sample is disassembled.
Further, to prevent the moving plate 702 from being angularly displaced during the movement, the detection assembly 7 further comprises a first slide bar 710 located below the threaded rod 707. The two ends of the first sliding bar 710 are respectively fixed on the two fixed blocks 706, and the first sliding bar 710 penetrates through the two moving plates 702. Furthermore, a second sliding bar 711 is disposed above the threaded bar 707, two ends of the second sliding bar 711 are also fixed to the two fixed blocks 706, and the second sliding bar 711 also penetrates through the two moving plates 702. To move the moving plate 702 smoothly, the axes of the second slide 711, the threaded rod 707, and the first slide 710 overlap in the vertical direction, as shown in fig. 5.
The moving plate 702 is provided with a clamping platform 703 and an electrode testing block 704, wherein the electrode testing block 704 is a part for clamping and testing a concrete sample, and the clamping platform 703 is a part for arranging a tray 705. Specifically, the electrode test block 704 is disposed on the upper portion of the moving plate 702, and the two electrode test blocks 704 are located inside the opposite surfaces of the two moving plates 702. To facilitate clamping of the concrete sample, the sides of the electrode test block 704 facing away from the moving plate 702 are each provided with a groove 712. When the two electrode test blocks 704 clamp the concrete sample, one end of the concrete sample can be first placed into the groove 712 of one of the electrode test blocks 704. In the process that the moving plate 702 drives the electrode test blocks 704 to move towards each other, the other one of the concrete samplesThe end enters the recess 712 of the other electrode test block 704, whereby the concrete sample is received and clamped by the recess 712, and thus does not slip off between the two electrode test blocks 704. In addition, when testing the durability of the concrete sample, NaCl solution and NaOH solution are respectively injected into two ends of the concrete sample so as to pass Cl-The ions achieve the detection of the electric flux. In order to facilitate the injection of the NaCl solution and the NaOH solution, in the portable concrete electric flux detector provided in the embodiment of the present application, a through hole 713 is further provided at the top of the electrode testing block 704, and the through hole 713 is communicated with the groove 712, so that the solution enters the end of the concrete sample through the through hole 713 and the groove 712.
In the portable concrete electric flux detector provided in the embodiment of the present application, the positive and negative electrodes of the two electrode test blocks 704 are not limited, and only one electrode test block is a positive electrode test block, and the other electrode test block is a negative electrode test block. In addition, the bottom of the groove 712 is provided with an electrode plate 717, so that the test cable 701 and the concrete sample are communicated through the electrode plate 717.
When the two moving plates 702 move towards each other, the two electrode testing blocks 704 also move towards each other, and the electrode testing blocks 704 directly clamp the concrete sample. When the electrode test blocks 704 move in opposite directions and there is no concrete sample between the two electrode test blocks 704, if the driving motor 714 always drives the moving plate 702 to move in opposite directions, the two electrode test blocks 704 are pressed against each other and wear occurs, so that the electrode test blocks 704 are damaged. To prevent excessive compression between the two electrode test bricks 704, the width of the connection snap ring 709 is greater than or equal to the sum of the widths of the two electrode test bricks 704. At this time, the moving plate 702 does not move any more after moving to the connecting snap ring 709, and thus the two electrode test blocks 704 do not collide with each other. Preferably, the width of the connection clamp ring 709 is equal to the sum of the widths of the two electrode test blocks 704, so that a concrete sample with a smaller thickness can be clamped between the two electrode test blocks 704.
Since the NaCl solution and the NaOH solution are injected into both ends of the concrete sample, respectively, when testing the durability of the concrete sample, the leakage prevention member 14 is disposed at the electrode test block 704 to prevent the leakage of the NaCl solution and the NaOH solution. As shown in fig. 6, the side of the electrode test block 704 facing away from the moving plate 702 is further provided with a gasket groove 715, the gasket groove 715 is communicated with the groove 712, and the groove 712 is located between the gasket groove 715 and the moving plate 702. The gasket groove 715 of the electrode test block 704 is used to movably couple the leak prevention member 14. Specifically, the leakage preventing member 14 includes a gasket 1401, an external thread 1403 is provided on the outer side of the gasket 1401, the electrode test block 704 is provided with an internal thread 716 at the gasket groove 715, and the external thread 1403 is matched with the internal thread 716. Thus, the leakage preventing member 14 can be fastened to the electrode test block 704 by the external and internal threads 1403 and 716, thereby preventing the solution from leaking from the groove 712.
Further, the grommet 14 further includes a rubber ring 1402 closely contacting the gasket 1401, and the rubber ring 1402 has a strong elasticity. Preferably, the gasket 1401 and the rubber ring 1402 are integrally formed. The outside of the rubber ring 1402 is provided with a freely adjustable locking band 1404. When it is desired to test a concrete sample, one end of the concrete sample is placed into the recess 712 of one of the electrode test blocks 704, and the leak prevention member 14 is fastened to the electrode test block 704 by the external and internal threads 1403 and 716. During the process that the moving plate 702 drives the electrode testing block 704 to move towards each other, the other end of the concrete sample enters into the other leakage-proof piece 14 and the groove 712 of the electrode testing block 704. After the concrete sample is clamped, the rubber ring 1402 is tightened on the concrete sample by the locking band 1404. Thereby, the electrode test block 704 and the concrete sample are further locked, and the effect of preventing the solution from leaking is achieved.
In the embodiment of the present application, the locking band 1404 may be an elastic ring structure component or a strip-shaped locking component. When the locking band 1404 is an elastic circular ring structural member, the diameter of the locking band 1404 is smaller than the diameter of the concrete sample to facilitate tightening of the rubber ring 1402 on the concrete sample. When the locking band 1404 is a strip-shaped locking part, one end of the locking band 1404 is provided with a clamping piece, and the other end is provided with a limiting hole, so that the rubber ring 1402 is tightened on the concrete sample through the locking of the clamping piece and the limiting hole. The embodiment of the present application does not limit the specific style of the locking band 1404, and the locking band 1404 capable of tightening the rubber ring 1402 on the concrete sample is within the protection scope of the present application.
Further, if the leak-proof member 14 is aged and not found to be renewed in time, a tray 705 is provided below the two electrode test blocks 704 in order to prevent the solution from leaking. Specifically, two opposite inner side surfaces of the two moving plates 702 are symmetrically provided with two clamping platforms 703, and the two clamping platforms 703 are located below the electrode testing block 704. The symmetrically arranged clamping platforms 703 are movably provided with a tray 705. After the two electrode test blocks 704 clamp the concrete sample, the tray 705 is removably snapped onto the two clamping platforms 703. Then, the NaCl solution and the NaOH solution are injected into the two ends of the concrete sample through the through holes 713 and the grooves 712, and the excess NaCl solution and the NaOH solution fall into the tray 705 along the bottom of the grooves 712, so that the tray 705 supports the solutions to prevent the leakage of the solutions. The arrangement of the clamping table and the tray on the movable plate can also prevent the solution from corroding the electric flux instrument after leaking, effectively reduces the loss of the instrument and prolongs the service life of the electric flux instrument.
The test cable 701 is a part for connecting the electrode test block 704 with the integrated circuit, and thus one end of the test cable 701 is connected to the electrode pad 717 in the electrode test block 704 and the other end is connected to the integrated circuit through the cable through-hole 6. The experimental data measured by the electrode test block 704 are transmitted to the integrated circuit through the test cable 701, and then displayed by the display 13. If the test cable 701 enters the inside of the tester body 2 from above the electrode test block 704, the electrode test block 704 may scrape the test cable 701 in the moving process of the moving plate 702, which causes problems such as dropping of the test cable 701, and thus the cable through hole 6 is located below the test table 5 in the embodiment of the present invention.
In the portable concrete electric flux detector that this application embodiment provided, multiunit determine module 7 parallel arrangement, and every group determine module 7 all is on a parallel with detector body 2, as shown in attached figure 1. At this time, the test cables 701 respectively connected to the two electrode test blocks 704 respectively enter the cable through holes 6 after respectively passing around the test table 5.
Or, in the portable concrete electric flux detector provided in the embodiment of the present application, multiple sets of detection assemblies 7 are arranged in parallel, and each set of detection assembly 7 is perpendicular to the detector body 2, as shown in fig. 6. At this time, the test cable 701 connected to one electrode test block 704 enters the cable through hole 6 after bypassing the test table 5; the test cable 701 connected to the other electrode test block 704 penetrates the test stage 5 and enters the cable through hole 6.
The above lists only two arrangements of the plurality of sets of detecting elements 7 in the embodiment of the present application, but the present application is not limited to the above two arrangements as long as the connection of the electrode testing block 704 to the integrated circuit can be realized through the testing cable 701.
The application method of the portable concrete electric flux detector provided by the embodiment of the application comprises the following steps:
