Description

Technical Field

[0001] The invention relates to the technical field of water seepage detection, and in particular to a water seepage detection device for a building wall. Background Art

[0002] Moisture meter is an instrument that can detect the water content in various organic and inorganic solid, liquid, gas and other samples. It can be classified into two categories according to the measurement principle: physical measurement method and chemical measurement method. Commonly used physical measurement methods include weight loss method, distillation stratification method, gas chromatography analysis method, etc. Chemical measurement methods mainly include Karl Fischer method, toluene method, etc. The International Organization for Standardization has set the Karl Fischer method as the international standard for measuring trace moisture, and our country has also set this method as the national standard for measuring trace moisture.

[0003] After the construction of the building wall is completed, the water seepage of the wall needs to be tested. The traditional testing method is to sprinkle water on one side of the wall, and then observe the water seepage on the other side of the wall to understand the water seepage of the wall. During the testing process, the testers will also use portable moisture meters to assist in the detection. Since the moisture meter is manually picked up for testing, the detection accuracy is reduced, and manual testing will cause detection errors due to manual intervention. Faced with multiple water seepage tests on the wall, it takes a lot of time for manual operation, that is, the current building wall water seepage detection efficiency is low.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 5 , the present invention provides a technical solution:

[0030] A water seepage detection device for a building wall comprises a base 1, the upper end of the base 1 is connected to a limit column 3, a rack 4 is slidably connected to the limit column 3, one side of the rack 4 is rotatably connected to a moisture meter 6, one end of the moisture meter 6 is connected to a detection contact 17, and the moisture meter 6 can detect the moisture content of the wall surface by abutting against the wall surface through the detection contact 17, so as to understand the water seepage situation of the wall surface;

[0031] The upper part of the base 1 is connected with a deflection claw 8 for limiting the height of the rack 4. When the height of the rack 4 rises, the deflection claw 8 will be repeatedly deflected, and the rack 4 can be limited by the deflection claw 8 to prevent the rack 4 from falling and allow the rack 4 to rise in height. When it is necessary to reset the height of the rack 4 structure, the deflection claw 8 can be pulled to ensure that the upper end of the deflection claw 8 is separated from the rack 4, so that the rack 4 structure falls freely to complete the reset, and the upper end of the deflection claw 8 abuts against the rack 4. A clip 7 is connected to the base 1, and a deflection shaft 22 is connected between the clips 7. The deflection claw 8 is rotatably connected to the deflection shaft 22. The lower end of the deflection claw 8 is connected to a deflection disk 21. The stability of the connection of the deflection spring 9 is improved by setting the deflection disk 21. A deflection spring 9 is connected between the deflection disk 21 and the clip 7. The deflection spring 9 is sleeved on the deflection shaft 22. The effect of the setting of the deflection spring 9 is to ensure that the upper end of the deflection claw 8 can deflect toward one side of the rack 4.

[0032] A lifting gear 25 is provided on one side of the rack 4 to drive the rack 4 to rise in height. When the lifting gear 25 is separated from the rack 4, the moisture meter 6 can perform wall water seepage detection. When the lifting gear 25 drives the rack 4 to rise in height, the moisture meter 6 is in the process of rising in height, and the contact between the detection contact 17 and the wall is unstable, which will cause the inspection data of the moisture meter 6 to fluctuate. Such fluctuating data will not be recorded, and the moisture meter 6 will only record stable data under stable conditions. A connecting plate 10 is connected to one side of the limit column 3, and a rotating mechanism is connected to the connecting plate 10 to drive the lifting gear 25 to rotate.

[0033] Specifically, Figure 1 As shown, a fixing block 2 is symmetrically connected to the outer side of the base 1, and a hole is opened on the fixing block 2. The operator can stabilize the connection position of the base 1 by inserting a rod-shaped structure into the hole.

[0034] Specifically, Figure 1 As shown, a connecting frame 5 is connected to the outside of the rack 4, and a rotating shaft 16 is connected to the outside of the moisture meter 6. The rotating shaft 16 is rotatably connected to the connecting frame 5, and the connecting frame 5 is slidably sleeved on the outside of the limit column 3. By setting the connecting frame 5, it is ensured that the rack 4 and the moisture meter 6 maintain synchronous lifting and lowering, and the square-shaped connecting frame 5 can also ensure the stability of the structural lifting and lowering.

[0035] Specifically, Figure 2 As shown, a fixing frame 14 is connected to the connecting frame 5, and a detection cylinder 15 is connected to the fixing frame 14. The detection cylinder 15 is arranged above the moisture meter 6. By arranging the detection cylinder 15, the deflection state of the moisture meter 6 can be corrected to ensure that the detection contact 17 can be stably abutted against the wall surface, thereby avoiding the moisture meter 6 structure from tilting during detection and interfering with the detection accuracy.

[0036] Specifically, Figure 4 and Figure 5 As shown, the rotating mechanism includes an F-shaped frame 32. The F-shaped frame 32 is arranged to avoid interfering with the deflection of the extension rod 35, so as to ensure that the extension rod 35 can be stably driven to rotate, thereby driving the lifting gear 25 to rotate. A translation bar 11 is horizontally slidably connected to one side of the connecting plate 10. A slide groove 30 is provided on the translation bar 11. A slider 31 is slidably connected to the slide groove 30. By providing the slide groove 30, the stability of the structure when the slider 31 is lifted up and down is improved. The F-shaped frame 32 is fixedly connected to the slider 31. A slide bar 24 is connected to one side of the slider 31. The slide bar 24 and the connecting plate 10 are in a vertical state. A bending groove 20 is provided on the connecting plate 10. The bending groove 20 is L-shaped and consists of a horizontal part and a vertical part. The slide bar 24 is slidably connected to the bending groove 20. A telescopic cylinder 13 is rotatably connected to the slide bar 11. The telescopic cylinder 13 is rotatably connected to one side of the connecting plate 10, and the lifting gear 25 is rotatably connected to one side of the translation bar 11.

[0037] A connecting block 33 is connected to the outer side of the lifting gear 25, and a rotating frame 1 34 is connected to the connecting block 33. A rotating frame 2 36 is rotatably connected to the rotating frame 1 34, and an extension rod 35 is connected to the rotating frame 2 36. The connecting block 33 and the extension rod 35 are abutted against each other. By setting the structure of the rotating frame 1 34 and the rotating frame 2 36, the extension rod 35 and the connecting block 33 are rotatably connected. Under normal conditions, the extension rod 35 can be in a state of abutment with the connecting block 33 at one end due to the action of gravity. However, in order to improve the stability of the connection between the extension rod 35 and the connecting block 33, a torsion spring structure can be set at the connection between the rotating frame 1 34 and the rotating frame 2 36, wherein the extension rod 35 can only deflect upward around one end of the connecting block 33.

[0038] Specifically, Figure 4As shown, the connecting plate 10 is connected to a slide rail 37 , and a slide clamp 23 is slidably connected to the slide rail 37 . The slide clamp 23 is fixedly connected to the translation bar 11 . The sliding stability of the translation bar 11 sliding on one side of the connecting plate 10 is improved by providing the slide clamp 23 .

[0039] Specifically, Figure 4 As shown, a rotating hole 26 is opened on the connecting plate 10, and a cylinder shaft 38 is rotatably connected to the rotating hole 26, and a cylinder sleeve 18 is connected to the cylinder shaft 38. The cylinder sleeve 18 is fixedly connected to the outside of the telescopic cylinder 13, and a push ring 19 is connected to the telescopic end of the telescopic cylinder 13. The push ring 19 is sleeved on the slide rod 24. During the telescopic process of the telescopic cylinder 13, the telescopic cylinder 13 itself will also rotate. The cylinder shaft 38 is provided to improve the rotation stability of the telescopic cylinder 13, wherein the rotating hole 26 is opened through the connecting plate 10.

[0040] Specifically, Figure 5 As shown, the upper end of the translation bar 11 is connected to a connecting frame 12, one end of the connecting frame 12 is connected to a spring disk 27, the spring disk 27 is connected to a gear shaft 29, the lifting gear 25 is rotatably connected to the gear shaft 29, and a reset spring 28 is connected between the lifting gear 25 and the spring disk 27. By setting the reset spring 28, the lifting gear 25 can automatically reset after rotation.

[0041] To sum up, the water seepage detection device for a building wall provided in the present embodiment needs to be moved to one side of the wall when water seepage detection of the building wall is needed, wherein the detection contact 17 needs to abut against the wall surface, and the operator can use the fixed block 2 to fix the device at the position to be detected, and then start the moisture meter 6 and the telescopic cylinder 13, wherein the moisture meter 6 can contact the wall surface through the detection contact 17 to detect the water content at the position, thereby understanding the water seepage condition of the wall surface at the position.

[0042] When the telescopic cylinder 13 is started and extended, the push ring 19 connected to the telescopic end of the telescopic cylinder 13 can push the slide bar 24 to slide on the bending groove 20. In the initial stage, the slide bar 24 slides horizontally on the bending groove 20. At this time, as the slide bar 24 moves in the horizontal direction, it can hook and push the translation bar 11 structure to move toward the rack 4. At this time, the lifting gear 25 moves synchronously toward the rack 4 until the slide bar 24 slides to one end of the horizontal part of the bending groove 20. At this time, the lifting gear 25 and the rack 4 are meshed with each other.

[0043] When the telescopic cylinder 13 continues to extend, the slide bar 24 will slide to the vertical part of the bending groove 20. At this time, the slide bar 24 starts to move downward in vertical height, driving the slider 31 to slide vertically downward on the slide groove 30. At this time, the position of the translation bar 11 remains unchanged, so the lifting gear 25 maintains the state of mutual meshing with the rack 4. When the height of the slider 31 decreases, it can drive the F-shaped frame 32 to decrease in height, so that the extension rod 35 is pulled downward by the F-shaped frame 32. At this time, the lifting gear 25 rotates, synchronously driving the gear 25 to rotate. The rack 4 is raised in height, wherein the limiting structure provided at the upper end of the deflection claw 8 can prevent the rack 4 from falling in height, and allow the rack 4 to rise in height, wherein the upper surface of the limiting structure provided at the upper end of the deflection claw 8 is a horizontal structure, and the lower surface thereof is an inclined structure, when the rack 4 rises in height, the deflection claw 8 is in a state of repeated small-angle deflection, and the lower end of the deflection claw 8 rotates around the deflection shaft 22, wherein the deflection spring 9 structure provided can drive the deflection claw 8 structure to deflect to one side of the rack 4, thereby preventing the rack 4 from falling in height;

[0044] When the slider 31 is lowered, the lifting gear 25 starts to rotate, and the return spring 28 starts to accumulate force. When the telescopic cylinder 13 is extended to the maximum state, the lifting gear 25 is deflected, and the rack 4 rises to a certain height. Then the telescopic cylinder 13 begins to shrink, and the F-frame 32 rises in height. At this time, the lifting gear 25 is limited by the rack 4, and the rack 4 is limited by the deflection claw 8. Therefore, the lifting gear 25 stops rotating, and the extension rod 35 is deflected by the F-frame 32, so that the F-frame 32 rises in height but does not drive the lifting gear 25 to rotate. When the slide bar 24 slides to the horizontal part of the bending groove 20 under the action of the telescopic cylinder 13, the lifting gear 25 is away from the rack 4. When the lifting gear 25 is separated from the rack 4, the lifting gear 25 is reset under the action of the return spring 28. At this time, the connecting block 33 and the extension rod 35 are in a state of abutting each other at one end again.

[0045] When the telescopic cylinder 13 contracts, the detection cylinder 15 begins to extend, thereby pushing the moisture meter 6 to deflect to a horizontal state. Since the moisture meter 6 is driven by the rack 4 structure to rise in height, the detection contact 17 contacts the wall and is affected by the wall, causing the moisture meter 6 to deflect obliquely downward. The function of the detection cylinder 15 is to restore the moisture meter 6 to a horizontal state, ensuring that the detection contact 17 can completely abut against the wall, thereby improving the detection accuracy. Since the moisture meter 6 rises in height intermittently and the height of each rise is fixed, water seepage detection can be performed on different heights on the same vertical line of the wall. Since the moisture meter 6 also performs water seepage detection when the height rises, but the detection value is inaccurate, it is necessary to take the stable data when the moisture meter 6 stops rising in height for the detection data, and perform water seepage detection at equidistant height rises, which can improve the detection accuracy. Among the different detection data, only the height of the detection wall changes, and the detection process is automatically completed, thereby avoiding errors caused by manual detection and improving the detection data accuracy and detection efficiency.
