Description

TECHNICAL FIELD

[0001] The utility model relates to concrete detection technical field, concretely related to a concrete impermeability detection device. BACKGROUND

[0002] Under the background of rapid development of contemporary society and economy, concrete plays an indispensable role in the field of civil engineering construction due to its diversified characteristics and wide applicability. However, the performance of concrete is significantly affected by its formula proportion, and even a small change in composition can lead to a significant difference in the quality of the final product. In view of this, it is particularly important to detect the impermeability of concrete. This is not only a key step to ensure the long-term stability and safety of various infrastructures, but also a necessary requirement to improve engineering durability. Therefore, it is necessary to use a concrete impermeability detection device to detect the impermeability of concrete.

[0003] For example, Chinese patent CN219694843U discloses a device for detecting the impermeability of concrete, which includes a detection device main body, a mounting seat, a placement module, a positioning structure and a limiting structure. The positioning structure constitutes a clamping structure between the positioning ring and the positioning rod, which realizes quick positioning of the placement module and the mounting seat, and facilitates quick installation after disassembly of the placement module. However, the above detection device needs to place all the concrete test pieces to be detected in the placement module before starting the detection, which greatly increases the time required for the entire detection process due to the slow placement by artificial, thereby reducing the detection efficiency of the detection device.

[0004] However, there is no effective solution to the problems in the related art. UTILITY MODEL CONTENTS

[0011] The beneficial effects of the present application are as follows:

[0029] In one embodiment, for the rotating mechanism 4 described above, the rotating mechanism 4 includes a motor 401 arranged at the top end of the base 3, the output end of the motor 401 is connected with a plurality of support rods 402, and the plurality of support rods 402 are evenly arranged and circumferentially distributed on the top of the anti-permeability detection box 1; after the operator places the first anti-permeability test piece 5 on the top end of one of the support rods 402, the support rod 402 is driven to rotate to the bottom of the anti-permeability detection box 1 for anti-permeability detection under the rotating action of the output shaft of the motor 401, and the operator can continue to place the next anti-permeability test piece 5 on the support rod 402 while detecting, so that the anti-permeability test piece 5 can be placed and detected simultaneously, thereby improving the anti-permeability detection efficiency.

[0030] The working principle of the rotating mechanism 4 is as follows: the operator places the first anti-permeability test piece 5 on the top end of the uppermost support rod 402, then fastens the anti-permeability test piece 5 on the top end of the support rod 402 through the fastening mechanism 6, and then rotates the support rod 402 to the bottom of the anti-permeability detection box 1 for anti-permeability detection under the rotating action of the output shaft of the motor 401, so that the operator can continue to place the next anti-permeability test piece 5 on the top end of the next support rod 402, and then continue to rotate, at this time, the first support rod 402 rotates to the bottom of the anti-permeability detection box 1 for anti-permeability detection, and the operator can continue to place the anti-permeability test piece 5 on the top end of the uppermost support rod 402 while detecting, so that the anti-permeability test piece 5 can be placed and detected simultaneously, thereby improving the anti-permeability detection efficiency, and when the detected anti-permeability test piece 5 rotates to the uppermost position again, the operator releases and takes out the detected anti-permeability test piece 5 from the fastening mechanism 6, and then places the next anti-permeability test piece 5 to be detected.

[0031] In one embodiment, for the above-mentioned fastening mechanism 6, the fastening mechanism 6 comprises a plurality of fastening rings 601 arranged outside the impermeable test piece 5, the outer side of the fastening ring 601 is symmetrically provided with a clamping block 602, the top end of the clamping block 602 is provided with an upper baffle 603, the bottom end of the clamping block 602 is provided with a lower baffle 604, the side of the lower baffle 604 away from the clamping block 602 is provided with a telescopic rod 605 connected with the top of the supporting rod 402; the outer side of the bottom of the clamping block 602 is provided with a lifting lug 606 at both ends, the end of the lifting lug 606 away from the impermeable test piece 5 is provided with a threaded rod 607, one end of the threaded rod 607 is provided with a handle 608, both ends of the outer side of the threaded rod 607 are provided with a threaded sleeve 609 matched therewith, and the threaded sleeve 609 is connected with the lifting lug 606 through a bolt; the clamping block 602 and the lower baffle 604 are both semicircular structures, the width of the lower baffle 604 is greater than the width of the upper baffle 603; the height of the impermeable test piece 5 is higher than the height of the clamping block 602; under the action of rotating the handle 608, the threaded sleeves 609 at both ends of the threaded rod 607 can approach each other, and drive the two sets of clamping blocks 602 to approach the impermeable test piece 5, until the two sets of clamping blocks 602 tightly adhere to the fastening ring 601 and cannot move any more, so as to fix the impermeable test piece 5 of different diameters at the top end of the supporting rod 402, and then the impermeable test piece 5 of different diameters can be detected.

[0032] In addition, it should be noted that the above-mentioned fastening ring 601 is made of elastic material for uniformly dispersing pressure.

[0035] In one embodiment, for the above-mentioned fastening ring 601, several fastening rings 601 are evenly arranged and linearly distributed between the outer side of the impermeable test piece 5 and the upper baffle 603 and the lower baffle 604. The fastening mechanism 6 can generate pressure on the impermeable test piece 5, which can be evenly dispersed on the impermeable test piece 5 through the fastening ring 601 under the isolation of the fastening ring 601 between the fastening mechanism 6 and the impermeable test piece 5, thereby preventing the fastening mechanism 6 from generating uneven pressure on the surface of the impermeable test piece 5 during fastening, and thereby avoiding affecting the test results.

[0036] In order to facilitate the understanding of the above technical solutions of the present application, the working principle or operation mode of the present application in the actual process will be described in detail below.

When the first placed impermeable test piece 5 is rotated to the bottom of the impermeable detection box 1, the water inside the impermeable detection box 1 can immerse the bottom surface of the impermeable test piece 5 at the bottom, and there is a distance between the water level in the box and the bottom end of the fastening mechanism 6 outside the impermeable test piece 5, so that the water in the box can gradually penetrate upward through the capillary pores of the impermeable test piece 5, thereby recording the height of the water rising on the side of the impermeable test piece 5 not immersed in water and the corresponding time point through the scale 7, and detecting the impermeability of the impermeable test piece 5. Then, the impermeable test piece 5 is rotated to the uppermost part of the impermeable detection box 1 by the rotating mechanism 4, and the fastening mechanism 6 is loosened to take out the impermeable test piece 5. Finally, according to the diameter of the impermeable test piece 5 and the recorded penetration height, combined with the test time, the impermeability index of the concrete is finally calculated.
